3. Calculated based on 8,625,000 redeemable warrants (the “Public Warrants”) and 9,900,000 redeemable warrants (the “Private Placement Warrants”), in each case issued by Altimar II, which will become warrants to purchase shares of Class A common stock in connection with the Business Combination.

4. Pursuant to Rule 416(a) of the Securities Act of 1933, as amended (the “Securities Act”), there are also being registered an indeterminable number of additional securities as may be issued to prevent dilution resulting from share splits, share dividends or similar transactions.

5.

After careful consideration, Altimar II’s board of directors has determined that each of the proposals set forth above is in the best interests of Altimar II and its shareholders and unanimously recommends that you vote or give instruction to vote “FOR” each of those proposals.

iv

The existence of financial and personal interests of Altimar II’s directors may result in a conflict of interest on the part of one or more of the directors between what he or they may believe is in the best interests of Altimar II and its shareholders and what he or they may believe is best for himself or themselves in determining to recommend that shareholders vote for the proposals. See the section entitled “The Business Combination Proposal — Interests of Altimar II Directors and Officers in the Business Combination” in the proxy statement/prospectus when it becomes available for a further discussion.

Under the Business Combination Agreement, the approval of each of the Condition Precedent Proposals is a condition to the consummation of the Business Combination. The adoption of each Condition Precedent Proposal is conditioned on the approval of all of the Condition Precedent Proposals. The Advisory Charter Proposals and the Adjournment Proposal are not conditioned on the approval of any other proposal. If our shareholders do not approve each of the Condition Precedent Proposals, the Business Combination may not be consummated.

In connection with our initial public offering, on February 4, 2021, Sponsor and our officers and directors at the time of our initial public offering entered into a letter agreement (the “IPO Letter Agreement”) pursuant to which they agreed, among other things, to vote their Class B ordinary shares purchased prior to our initial public offering (“founder shares”), as well as any Class A ordinary shares sold by us in our initial public offering (“public shares”) purchased by them during or after our initial public offering, in favor of Altimar II’s initial business combination (including the proposal recommended by Altimar II’s board of directors in connection with such business combination).

Accordingly, we expect them to vote their shares in favor of all proposals being presented at the Special Meeting. In addition, pursuant to the Forfeiture and Support Agreement, dated July 15, 2021 and as amended on November 16, 2021 (as may be further amended from time to time, the “Forfeiture and Support Agreement”), the parties, agreed, among other things, effective upon the Closing that, (a) Sponsor, on behalf of itself and the other Altimar II Founders, will waive the anti-dilution adjustments set forth in Altimar II’s existing Memorandum and Articles of Association and which will be set forth in Altimar II’s Certificate of Incorporation in connection with the Business Combination, (b) the Altimar II Founders will forfeit and surrender for no additional consideration the Forfeited Shares (as defined herein) and (c) Sponsor, from the date of the Business Combination Agreement until the earlier of Closing or the termination of the Business Combination Agreement in accordance with its terms, will refrain from taking (and not cause Altimar II to take) any action the effect of which would be to cause Altimar II to breach its non-solicitation obligations set forth in Section 9.08 of the Business Combination Agreement. In addition, the Altimar II Founders agreed, among other things, (i) from the date of the Business Combination Agreement until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, to not redeem any Class A ordinary shares (or, if applicable, shares of Altimar II Class A common stock) held by them and (ii) prior to the consummation of Business Combination or the termination of the Business Combination Agreement, to vote or cause to be voted, all of the Altimar II shares beneficially owned by the Altimar II Founders, at every meeting of the shareholders of Altimar II at which such matters are considered and at every adjournment or postponement thereof: (1) in favor of (A) the Business Combination and the Business Combination Agreement and the other transactions contemplated thereby (including any proposals recommended by Altimar II’s Board of Directors in connection with the Business Combination) and (B) any proposal to adjourn or postpone such meeting of shareholders to a later date if there are not sufficient votes to approve the Business Combination; (2) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of Altimar II under the Business Combination Agreement; and (3) against (A) any proposal or offer from any person concerning (I) a merger, consolidation, liquidation, recapitalization, share exchange or other business combination transaction involving Altimar II, or (II) the issuance or acquisition of shares of capital stock or other Altimar II equity securities (other than as contemplated or permitted by the Business Combination Agreement); and (B) any action, proposal, transaction or agreement that would reasonably be expected to (x) impede the fulfillment of Altimar II’s conditions under the Business Combination Agreement or change in any manner the voting rights of any class of Altimar II’s shares or (y) result in a breach of any covenant, representation or warranty or other obligation or agreement of Sponsor or any of the other Altimar II Founders contained in the Forfeiture and Support Agreement.

v

Pursuant to Altimar II’s Existing Organizational Documents, a holder of public shares (“Public Shareholder”) may request that Altimar II redeem all or a portion of its public shares (which would become shares of Class A common stock in the Domestication) for cash if the Business Combination is consummated. For the purposes of Article 49.3 of the Existing Organizational Documents and the Cayman Islands Companies Act (As Revised), the exercise of redemption rights shall be treated as an election to have such public shares repurchased for cash and references in the proxy statement/prospectus relating to the Business Combination shall be interpreted accordingly. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i) (a) hold public shares or (b) hold units and you elect to separate your units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii) prior to                 5:00 p.m., Eastern Time, on                 , 2021, (a) submit a written request to Continental Stock Transfer & Trust Company, Altimar II’s transfer agent (the “transfer agent”), that Altimar II redeem your public shares for cash and (b) deliver your public shares to the transfer agent, physically or electronically through Depository Trust Company (“DTC”).

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent, directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares even if they vote for the Business Combination Proposal. If the Business Combination is not consummated, the public shares will not be redeemed for cash. If a Public Shareholder properly exercises its right to redeem its public shares and timely delivers its shares to the transfer agent, we will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account established in connection with our initial public offering (the “Trust Account”), calculated as of two business days prior to the consummation of the Business Combination, including interest, less income taxes payable, divided by the number of then issued and outstanding public shares. For illustrative purposes, as of                 , 2021, this would have amounted to approximately $    per public share. If a public shareholder exercises its redemption rights, then it will be exchanging its redeemed public shares for cash and will no longer own such shares. See “The Extraordinary General Meeting — Redemption Rights” in the proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to redeem your public shares for cash.

Notwithstanding the foregoing, a Public Shareholder, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (“Exchange Act”)), will be restricted from redeeming its public shares with respect to more than an aggregate of 15% of the public shares. Accordingly, if a Public Shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

The total consideration to be paid to the Fathom Blocker Owners and the Continuing Fathom Unitholders (each as defined herein), including CORE Industrial Partners Fund I, LP, at the Closing shall equal the aggregate of:

(a) (i) All the cash proceeds from the Trust Account established for the purpose of holding the net proceeds of Altimar II’s initial public offering, net of any amounts paid to Altimar II’s shareholders that exercise their redemption rights in connection with the Business Combination, together with the proceeds from the PIPE Investment (as defined herein) (the “Available Cash Amount”), (ii) minus $10,000,000 to be contributed by Altimar II to the balance sheet of Fathom OpCo, (iii) minus $20,000,000 to be used to pay down certain indebtedness of Fathom OpCo, (iv) minus certain transaction expenses of Fathom OpCo and Altimar II, which include fees and expenses of various advisors, transfer taxes, employee transaction bonuses, and filing and listing fees (the “Closing Cash Consideration”);

vi

(b) A number of shares of Class A common stock and newly issued Class A units of Fathom OpCo (the “New Fathom Units”) (together with one share of Class B common stock to be issued at par value for cash in respect of each New Fathom Units), to be allocated as set forth on a schedule, dated as of the Closing Date, setting forth (i) the name of each Continuing Fathom Unitholder and Fathom Blocker Owner, and (ii) the allocation of the Closing Cash Consideration, the Closing Seller Equity Consideration and the Earnout Shares at the Closing to each of the Continuing Fathom Unitholders and Fathom Blocker Owners (the “Allocation Schedule”), in an aggregate number (rounded up to the nearest whole share) equal to (a) the quotient of (i) the result of (A) $1,200,000,000 minus (B) the Closing Cash Consideration divided by (ii) $10.00 plus (b) 1,293,750, in each case of clauses (a) and (b), to be allocated as set forth on the Allocation Schedule (the “Closing Seller Equity Consideration”); and

(c) An aggregate of 9,000,000 shares of earnout equity consideration (in Class A common stock and New Fathom Units) (the “Earnout Shares”). These earnout shares will vest in three equal tranches of 3,000,000 shares, with each tranche vesting at each of the following share price thresholds: $12.50, $15.00 and $20.00, in each case subject to the vesting and forfeiture provisions set forth in the Investor Rights Agreement (as defined herein) and Fathom OpCo’s Amended and Restated Limited Liability Company Agreement (the “Fathom Operating Agreement”). The earnout period will be five years from the date of the closing of the Business Combination. The achievement of the price threshold will be determined based on a VWAP for 20 trading days within any 30-trading day period or a change of control transaction of Fathom that implies the same per share valuation as the applicable price threshold.

The Closing is subject to certain customary conditions, including, among other things: (i) the approval of the Business Combination and other matters by Altimar II’s shareholders; (ii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and receipt of certain additional regulatory approvals; (iii) the Available Cash Amount equaling no less than $90,000,000 (after giving effect to the receipt of proceeds from the Backstop Investment (as defined below), if applicable) at the Closing (such condition, the “Available Cash Amount Condition”); (iv) (x) fundamental representations and warranties (which includes Organization, Due Authorization, Holding Company; Ownership and Brokers’ Fees) bring down conditions to an “all material respects” standard, (y) general representations and warranties bring down conditions to a “material adverse effect” standard and (z) capitalization representation bring down condition to a “de minimis” standard; (v) covenant bring down conditions to an “all material respects” standard; (vi) the absence of a material adverse effect on the respective parties; and (vii) the effectiveness of this registration statement and the listing of Fathom Class A common stock to be issued in the Business Combination on the New York Stock Exchange (“NYSE”). To the extent permitted by law, the conditions in the Business Combination Agreement may be waived by the parties thereto.

In connection with entering into the Business Combination Agreement, Altimar II and Fathom OpCo entered into subscription agreements (the “Original PIPE Subscription Agreements”), each dated as of July 15, 2021, with certain institutional and other accredited investors (the “Original PIPE Investors”), pursuant to which, among other things, the PIPE Investors party thereto agreed to purchase an aggregate of 8,000,000 shares of Class A common stock following the Domestication and immediately prior to the Closing at a cash purchase price of $10.00 per share (the “Original PIPE Investment”). The Original PIPE Subscription Agreements contain customary representations, warranties, covenants and agreements of Altimar II, Fathom OpCo and the Original PIPE Investors and are subject to customary closing conditions (including, without limitation, that there is no amendment or modification to the Business Combination Agreement that is material and adverse to the Original PIPE Investor) and termination rights (including a termination right if the transaction contemplated by the Original PIPE Subscription Agreement has not been consummated by December 31, 2021, other than as a result of breach by the terminating party).

On November 16, 2021, Altimar II and Fathom OpCo entered into a subscription agreement with the CORE Investors (as defined below in “Selected Definitions”) pursuant to which, the CORE Investors (the “Backstop Investors”) agreed to purchase an aggregate of up to 1,000,000 shares of Class A common stock following the

vii

Domestication and immediately prior to the Closing at a cash purchase price of $10.00 per share (the “Backstop Investment” and together with the Original PIPE Investment, the “PIPE Investment”) only if (i) the Available Cash Amount is less than $90,000,000 and (ii) the Available Cash Shortfall (as defined below in “Selected Definitions”) does not exceed $10,000,000 (such agreement, the “CORE Backstop Agreement” and together with the Original PIPE Subscription Agreements, the “PIPE Subscription Agreements”).

Many of the terms used in this proxy statement/prospectus, including Adjusted EBITDA and Pro Forma Adjusted EBITDA, may not be comparable to similarly titled measures used by other companies. Further, Adjusted EBITDA and Pro Forma Adjusted EBITDA are not measures of performance calculated in accordance with GAAP. We use Adjusted EBITDA and Pro Forma Adjusted EBITDA as measures of operating performance, not as measures of liquidity. They should not be considered in isolation or as substitutes for operating income, net income, operating cash flows or other income or cash flow statement data prepared in accordance with GAAP. The use of these measures without consideration of related GAAP measures is not adequate due to the adjustments described above. Our management compensates for these limitations by using non-GAAP measures as supplemental measures to our GAAP results. We present these measures to provide a more complete understanding of our performance as our management measures it. Amounts and percentages throughout this proxy statement/prospectus may reflect rounding adjustments and consequently totals may not appear to sum. For reconciliations of non-GAAP measures used by Fathom OpCo to Fathom OpCo’s GAAP results, see “Fathom OpCo’s Management’s Discussion and Analysis of Financial Condition and Results of Operations — Reconciliation of Consolidated GAAP Financial Measures to Certain Non-GAAP Measures”.

Share Calculations and Ownership Percentages

Unless otherwise specified, the share calculations and ownership percentages set forth in this proxy statement/prospectus with respect to the ownership of Fathom immediately following the completion of the Business Combination are for illustrative purposes only and assume the following:

1. The Original PIPE Investors acquire 8,000,000 shares of Class A common stock in connection with the Closing, for an aggregate purchase price of $80 million.

2. No Altimar II Public Shareholders exercise their redemption rights in connection with the Business Combination and as a result of the foregoing assumption, no Class A common stock will be forfeited by the Altimar II Founders.

3. The balance of the Trust Account as of the Closing is, and (as a result of the foregoing assumptions) the available proceeds from the Trust Account are, approximately $345 million. As a result, the Available Cash Amount is equal to approximately $425 million.

4. The Debt Pay-Down Amount (i.e., amount of the indebtedness of Fathom OpCo to be paid down at the Closing from funds in the Trust Account) is equal to $20 million.

5. The Balance Sheet Contribution is equal to $10 million.

6. None of the Warrants have been exercised and no shares of Class A common stock reserved for issuance under the proposed 2021 Omnibus Plan and the ESPP Plan have been issued.

8. Earnout Shares and Sponsor Earnout Shares are not vested.

10. Pro rata forfeiture by Altimar II Founders of an aggregate of 2,587,500 shares of Class A common stock.

As a result of the assumptions set forth above:

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

AND THE EXTRAORDINARY GENERAL MEETING

The following are answers to certain questions that you may have regarding the Business Combination and the shareholder meeting. We urge you to read carefully the remainder of this proxy statement/prospectus because the information in this section may not provide all the information that might be important to you in determining how to vote. Additional important information is also contained in the annexes to this proxy statement//prospectus.

QUESTIONS AND ANSWERS ABOUT THE BUSINESS COMBINATION

Q: WHAT IS THE BUSINESS COMBINATION?

A: Altimar II and Fathom OpCo have entered into the Business Combination Agreement, dated as of July 15, 2021 and subsequently amended on November 16, 2021, pursuant to which, among other things:

(a) Altimar II will change its jurisdiction of incorporation by deregistering as an exempted company in the Cayman Islands and continuing and domesticating as a corporation under the laws of the State of Delaware (the “Domestication”), upon which Altimar II will change its name to “Fathom Digital Manufacturing Corporation.”

(b) Fathom OpCo will issue managing member interests in Fathom OpCo to Altimar II in exchange for a nominal cash payment; and

(c) Following a series of reorganization transactions among certain equity holders of Fathom OpCo’s businesses (the “Fathom Blockers”) and Altimar II, as specified in the Business Combination Agreement, Rapid Merger Sub, LLC, a wholly owned subsidiary of Altimar II, will merge with and into Fathom OpCo (the “Fathom Merger”), with Fathom OpCo as the surviving entity of the Fathom Merger (Fathom OpCo, in its capacity as the surviving entity of the Fathom Merger, is sometimes referred to as the “Fathom Surviving Entity”). Following the Fathom Merger, the Fathom Surviving Entity will be owned by Altimar II and all other holders of Fathom OpCo units outstanding as of immediately prior to the Fathom Merger (such other holders, excluding Altimar II, are referred to as the “Continuing Fathom Unitholders”).

Upon consummation of the transactions contemplated by the Business Combination Agreement, the combined company will be organized in an “Up-C” structure, in which substantially all of the assets and business of the combined company will be held by Fathom OpCo. Altimar II and the Continuing Fathom Unitholders will be issued Class A units of Fathom OpCo (“New Fathom Units”). Altimar II will be the managing member of Fathom OpCo. Altimar II will issue to Continuing Fathom Unitholders for cash at par value a number of shares of Class B common stock equal to the number New Fathom Units held by the Continuing Fathom Unitholders. Altimar II’s other stockholders will hold Class A common stock of the combined company. Shares of Class A common stock will be entitled to economic rights and one vote per share and shares of Class B common stock will be entitled to one vote per share but no economic rights. The combined company’s business will continue to operate through Fathom OpCo.

Altimar II will hold the Special Meeting to, among other things, obtain the approvals required for the Business Combination and the other transactions contemplated by the Business Combination Agreement and you are receiving this proxy statement/prospectus in connection with such meeting. See “The Business Combination Agreement” beginning on page 102. In addition, a copy of the Business Combination Agreement is attached to this proxy statement/prospectus as Annex C. We urge you to read carefully this proxy statement/prospectus and the Business Combination Agreement in their entirety.

A: Altimar II is sending this proxy statement /prospectus to its shareholders to help them decide how to vote their shares of Altimar II ordinary shares with respect to the matters to be considered at the Special Meeting.

This document constitutes a proxy statement of Altimar II and a prospectus of Altimar II.

Assuming maximum redemptions by Altimar II Public Shareholders and subject to the other assumptions set forth in “Unaudited Pro Forma Condensed Combined Financial Information”, Altimar II’s non-redeeming Public Shareholders will own 0% of the fully-diluted common equity of Fathom following the Business Combination.

Q: WHAT WILL ALTIMAR II FOUNDERS OWN AS A RESULT OF THE BUSINESS COMBINATION?

(a) (i) All the cash proceeds from the Trust Account established for the purpose of holding the net proceeds of Altimar II’s initial public offering, net of any amounts paid to Altimar II’s shareholders that exercise their redemption rights in connection with the Business Combination, together with the proceeds from the PIPE Investment (as defined herein) (the “Available Cash Amount”), (ii) minus $10,000,000 to be contributed by Altimar II to the balance sheet of Fathom OpCo, (iii) minus $20,000,000 to be used to pay down certain indebtedness of Fathom OpCo, (iv) minus certain transaction expenses of Fathom OpCo and Altimar II, which include fees and expenses of various advisors, transfer taxes, employee transaction bonuses, and filing and listing fees (the “Closing Cash Consideration”);

(b) A number of shares of Class A common stock and New Fathom Units (together with one share of Class B common stock to be issued at par value for cash in respect of each New Fathom Units), to be allocated in accordance with the allocation schedule to be delivered at the Closing (the “Allocation Schedule”), in an aggregate number (rounded up to the nearest whole share) equal to (a) the quotient of (i) the result of (A) $1,200,000,000 minus (B) the Closing Cash Consideration divided by (ii) $10.00 (the “Closing Seller

15

Equity Consideration”) plus (ii) 1,293,750 in each case of clauses (a) and (b), to be allocated as set forth on the Allocation Schedule (the “Closing Seller Equity Consideration); and

(c) An aggregate of 9,000,000 shares of Class A common stock and New Fathom Units (the “Earnout Shares”). These earnout shares will be issued in three equal tranches of 3,000,000 shares and allocated in accordance with the Allocation Schedule, with each tranche vesting at each of the following share price thresholds: $12.50, $15.00 and $20.00, in each case subject to the vesting and forfeiture provisions set forth in the Investor Rights Agreement (as defined herein) and Fathom OpCo’s Amended and Restated Limited Liability Company Agreement (the “Fathom Operating Agreement”). The earnout period will be five years from the date of the closing of the Business Combination. The achievement of the price threshold will be determined based on a VWAP for 20 trading days within any 30-trading day period or a change of control transaction of Fathom that implies the same per share valuation as the applicable price threshold.

The methodology to be followed in the Allocation Schedule at the Closing will provide for the payment of approximately $             of the Closing Cash Consideration to direct and indirect holders of outstanding preferred units of Fathom OpCo (including accrued but unpaid preferred distributions thereon), and will allocate the balance of the Closing Cash Consideration and the total Closing Seller Equity Consideration to direct and indirect holders of outstanding common units of Fathom OpCo, on a pro rata basis in accordance with the number of outstanding common units held. The Earnout Shares will be allocated in accordance with the Allocation Schedule to the direct and indirect holders of outstanding common units of Fathom OpCo on a pro rata basis in accordance with the number of outstanding common units held. The portion of the Closing Cash Consideration to be paid to direct and indirect holders of outstanding preferred units of Fathom OpCo as described above assumes, for illustration, the inclusion of accrued preferred distributions through                     , 2021. The total amount to be paid to the holders of preferred units will vary to reflect the accrued preferred distributions as of the Closing Date.

Q: WHAT INFLUENCE WILL THE CORE INVESTORS HAVE ON FATHOM’S MANAGEMENT AND POLICIES FOLLOWING THE BUSINESS COMBINATION?

A: Immediately following completion of the Business Combination and assuming no redemptions by Altimar II’s Public Shareholders, the CORE Investors will beneficially own approximately 46.1% of our Class A common stock and Class B common stock (or 63.7% assuming maximum redemptions by Altimar II Public Shareholders and not counting the Backstop Shares as part of the CORE Investors’ pro forma ownership). The Class A common stock and Class B common stock generally will vote together on matters submitted to a vote of our stockholders, including the election of directors. As a result, the CORE Investors will have the ability to influence our business and affairs through “negative control” rights resulting from their ownership of our Class A common stock and Class B common stock combined with certain supermajority voting provisions of the Proposed Charter and Proposed Bylaws, their general ability to vote on the election of directors to our board and the provisions in the Investor Rights Agreement described below.

In addition, in connection with the Business Combination, we will enter into the Investor Rights Agreement with the CORE Investors which will provide for an initial eleven-person board of directors, initially consisting of nine individuals to be designated by the CORE Investors, and one independent director to be mutually agreed by the CORE Investors and the Sponsor. The CORE Investors will have certain continued nomination rights for a number of directors ranging from the majority of the board of directors to one director, while they beneficially own shares of common stock in excess of certain ownership percentage of the amount owned by the CORE Investors at Closing, as determined in accordance with the Investor Rights Agreement. See “The Business Combination Agreement – Related Agreements – Investor Rights Agreement and Registration Rights Agreement” for more details with respect to the Investor Rights Agreement.

16

Q: WHEN WILL THE BUSINESS COMBINATION BE COMPLETED?

A: The parties currently expect that the Business Combination will be completed in December 2021. However, neither Altimar II nor Fathom OpCo can assure you of when or if the Business Combination will be completed, and it is possible that factors outside of the control of Altimar II and Fathom OpCo could result in the Business Combination being completed at a different time or not at all. The outside date for consummation of the Business Combination is December 31, 2021. Altimar II must first obtain the approval of Altimar II shareholders for each of the Condition Precedent Proposals, Fathom OpCo must obtain the approval of its members, and Altimar II and Fathom OpCo must also first obtain certain necessary regulatory approvals and satisfy other closing conditions. See “The Business Combination Agreement — Conditions to Closing of the Business Combination Agreement.”

Q: WHAT HAPPENS IF THE BUSINESS COMBINATION IS NOT COMPLETED?

A: If Altimar II does not complete the Business Combination with Fathom OpCo for any reason, Altimar II would need to search for another target business with which to complete a business combination. If Altimar II does not complete the Business Combination with Fathom OpCo or a business combination with another target business by February 9, 2023, Altimar II must redeem 100% of the outstanding Class A ordinary shares, at a per-share price, payable in cash, equal to the amount then held in the Trust Account (less income taxes paid or payable, if any, and up to $100,000 of interest to pay dissolution expenses) divided by the number of then outstanding Class A ordinary shares. The Sponsor has no redemption rights in the event a business combination is not effected in the required time period and, accordingly, its founder shares will be worthless. Additionally, in the event of such liquidation, there will be no distribution with respect to Altimar II’s outstanding warrants. Accordingly, such warrants will expire worthless.

QUESTIONS AND ANSWERS ABOUT OUR EXTRAORDINARY GENERAL MEETING

Q: WHAT AM I BEING ASKED TO VOTE ON AND WHY IS THIS APPROVAL NECESSARY?

A: Altimar II shareholders are being asked to vote on the following Shareholder Proposals:

1. the Business Combination Proposal;

2. the Domestication Proposal;

3. the Organizational Documents Proposal;

4. the Advisory Charter Proposals;

5. the Stock Issuance Proposal;

6. the Business Combination Issuance Proposal;

7. the Equity Incentive Plan Proposal;

8. the ESPP Proposal; and

9. the Adjournment Proposal.

The Business Combination is conditioned upon the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal and the EPP Proposal, subject to the terms of the Business Combination Agreement. The Business Combination is not conditioned on the approval of the Advisory Charter Proposals or the Adjournment Proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the shareholders for a vote.

Q: WHY IS ALTIMAR II PROPOSING THE BUSINESS COMBINATION?

A: Altimar II was incorporated to effect a merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more businesses or entities (each, a “business combination”).

17

On February 9, 2021, Altimar II completed its IPO, generating gross proceeds of $345,000,000 (including the full exercise of the underwriters’ over-allotment option). Since Altimar II’s initial public offering, Altimar II’s activity has been limited to the evaluation of business combination candidates.

Fathom OpCo, doing business as Fathom Digital Manufacturing, is a leading on-demand digital manufacturing platform in North America, providing comprehensive product development and manufacturing services to many of the largest and most innovative companies in the world.

The board of directors of Altimar II and the board of managers of Fathom OpCo have unanimously approved the proposed transaction. The proposed Business Combination will create a publicly traded leader in the $25 billion low-to-mid volume on-demand manufacturing industry.

Based on its due diligence investigation of Fathom OpCo and the industry in which it operates, including the financial and other information provided by Fathom OpCo in the course of its negotiations in connection with the Business Combination Agreement, Altimar II believes that Fathom will have a uniquely attractive financial profile due to its compelling growth trajectory, robust margins, strong software platform and the highly fragmented, opportunity rich $25 billion low-to-mid volume market in which it operates. Specifically, Fathom’s unique “one-stop-shop” solution and scale will be difficult to replicate. As a result, Altimar II believes that Fathom will be well positioned to be a long-term leader in the $25 billion low-to-mid volume on-demand manufacturing industry, and that the Business Combination with Fathom OpCo will provide Altimar II shareholders with an opportunity to participate in the ownership of a company with significant growth potential.

Q: DID THE ALTIMAR II BOARD OBTAIN A THIRD-PARTY VALUATION OR FAIRNESS OPINION IN DETERMINING WHETHER OR NOT TO PROCEED WITH THE BUSINESS COMBINATION?

A: Altimar II’s board of directors did not obtain a third-party valuation or fairness opinion in connection with its determination to approve the Business Combination.

Altimar II’s officers, directors and advisors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of Altimar II’s financial advisors, enabled them to make the necessary analyses and determinations regarding the Business Combination. In addition, Altimar II’s officers, directors and advisors have substantial experience with mergers and acquisitions. Accordingly, investors will be relying solely on the judgment of Altimar II’s officers, board of directors and advisors in valuing Fathom OpCo’s business.

Q: DO I HAVE REDEMPTION RIGHTS?

A: If you are a holder of Class A ordinary shares, you have the right to demand that Altimar II redeem such shares for a pro rata portion of the cash held in the Trust Account, which holds the proceeds of Altimar II’s IPO, as of two business days prior to the consummation of the transactions contemplated by the Business Combination Proposal (including interest earned on the funds held in the Trust Account and not previously released to Altimar II to pay its taxes) upon the closing of the transactions contemplated by the Business Combination Agreement (such rights, “Redemption Rights”).

Notwithstanding the foregoing, a holder of Class A ordinary shares, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption with respect to more than 15% of the Class A ordinary shares. Accordingly, all Class A ordinary shares in excess of 15% held by a Public Shareholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group”, will not be redeemed.

If passed, the Organizational Documents Proposal would remove the requirement that Altimar II have at least $5,000,001 of net tangible assets after giving effect to the redemption of all such shares.

18

Q: WILL HOW I VOTE AFFECT MY ABILITY TO EXERCISE REDEMPTION RIGHTS?

A: No. You may exercise your redemption rights whether you vote your Class A ordinary shares for or against, or whether you abstain from voting on, the Business Combination Proposal or any other Shareholder Proposal. As a result, the Business Combination Proposal can be approved by shareholders who will redeem their Class A ordinary shares and no longer remain shareholders and subject to the terms and conditions of the BCA, the Business Combination may be consummated even though the funds available from the Trust Account and the number of Public Shareholders are substantially reduced as a result of redemptions by Public Shareholders. Also, with fewer Class A ordinary shares and Public Shareholders, the trading market for Altimar II Class A ordinary shares may be less liquid than the market for Altimar II Class A ordinary shares prior to the Business Combination and Altimar II may not be able to meet the listing standards of a national securities exchange. In addition, with fewer funds available from the Trust Account, the capital infusion from the Trust Account into Fathom OpCo’s business will be reduced.

Q: HOW DO I EXERCISE MY REDEMPTION RIGHTS?

A: If you are a holder of Class A ordinary shares and wish to exercise your redemption rights, you must demand that Altimar II redeem your shares for cash no later than the second business day preceding the vote on the Business Combination Proposal by delivering your share certificates (if any) and other redemption forms to Altimar II’s transfer agent physically or electronically using Depository Trust Company’s DWAC (Deposit and Withdrawal at Custodian) system prior to the vote at the Special Meeting. Holders of units must elect to separate the underlying Class A ordinary shares and public warrants prior to exercising redemption rights with respect to the Class A ordinary shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into underlying Class A ordinary shares and public warrants, or if a holder holds units registered in its own name, the holder must contact Continental Stock Transfer & Trust Company, Altimar II’s transfer agent, directly and instruct them to do so. Any holder of Class A ordinary shares will be entitled to demand that such holder’s shares be redeemed for a full pro rata portion of the amount then in the Trust Account (which, for illustrative purposes, was approximately $                million, or $                per share, as of                 , 2021, the record date). Such amount, including interest earned on the funds held in the Trust Account and not previously released to Altimar II to pay its taxes, if any (less up to $100,000 of interest to pay dissolution expenses), will be paid promptly upon consummation of the Business Combination. However, the proceeds deposited in the Trust Account could become subject to the claims of Altimar II’s creditors, if any, which could have priority over the claims of Altimar II’s Public Shareholders, regardless of whether such Public Shareholders vote for or against the Business Combination Proposal. Therefore, the per-share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. Your vote on any Shareholder Proposal will have no impact on the amount you will receive upon exercise of your redemption rights.

Any request for redemption made by a holder of Class A ordinary shares may not be withdrawn once submitted to Altimar II unless the board of directors of Altimar II determines (in its sole discretion) to permit the withdrawal of such redemption request (which it may do in whole or in part).

Any written demand of redemption rights must be received by Altimar II’s transfer agent prior to the vote taken on the Business Combination Proposal at the Special Meeting. No demand for redemption will be honored unless the holder’s share certificates (if any) and other redemption forms have been delivered (either physically or electronically) to the transfer agent prior to the vote at the Special Meeting.

If a holder of Class A ordinary shares properly makes a request for redemption and the certificates for the Class A ordinary shares (if any) along with the redemption forms are delivered as described to Altimar II’s transfer agent as described herein, then, if the Business Combination is consummated, Altimar II will redeem these shares for a pro rata portion of funds deposited in the Trust Account. If you exercise your redemption rights, then you will be exchanging your Class A ordinary shares for cash.

19

Q: WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF EXERCISING MY REDEMPTION RIGHTS?

A: We expect that a U.S. holder (as defined in “Material U.S. Federal Income Tax Considerations — U.S. Holders” below) that exercises its redemption rights to receive cash from the Trust Account in exchange for its public shares will generally be treated as selling such public shares resulting in the recognition of capital gain or capital loss. There may be certain circumstances in which the redemption may be treated as a distribution for U.S. federal income tax purposes depending on the amount of Fathom common stock that a U.S. holder owns or is deemed to own (including through the ownership of Fathom warrants). For a more complete discussion of the U.S. federal income tax considerations of an exercise of redemption rights, see “Material U.S. Federal Income Tax Considerations”. Additionally, because the Domestication will occur immediately prior to the redemption of U.S. holders that exercise redemption rights, U.S. holders exercising redemption rights will be subject to the potential tax consequences of Section 367 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”) and the potential tax consequences of the rules applicable to a company treated as a “passive foreign investment company” (“PFIC”), as a result of the Domestication. The tax consequences of exercising redemption rights are discussed more fully below under “Material U.S. Federal Income Tax Considerations — U.S. Holders — Effect to U.S. Holders of Altimar II Ordinary Shares Exercising Redemption Rights.”

Q: DO I HAVE APPRAISAL RIGHTS IN CONNECTION WITH THE PROPOSED BUSINESS COMBINATION AND THE PROPOSED DOMESTICATION?

A: No. Neither Altimar II shareholders nor Altimar II warrantholders have appraisal rights in connection with the Business Combination or the Domestication under Cayman Islands law or under the DGCL.

Q: WHY IS ALTIMAR II PROPOSING THE DOMESTICATION?

A: Altimar II’s board of directors believes that there are significant advantages to Fathom that will arise as a result of a change of domicile to Delaware, including, (i) the prominence, predictability and flexibility of Delaware law, (ii) Delaware’s well-established principles of corporate governance and (iii) the increased ability for Delaware corporations to attract and retain qualified directors, each of the foregoing as discussed in greater detail in the section entitled “Proposal No. 2 — The Domestication Proposal — Reasons for the Domestication.” Altimar II’s board of directors believes that any direct benefit that Delaware law provides to a corporation also indirectly benefits shareholders, who are the owners of the corporation. Additionally, Fathom OpCo has required the Domestication as a condition to consummating the Business Combination.

To effect the Domestication, Altimar II will file a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and file a certificate of incorporation and a certificate of corporate domestication with the Secretary of State of the State of Delaware, under which Altimar II will be domesticated and continue as a Delaware corporation, at which time Altimar II will change its name to “Fathom Digital Manufacturing Corporation.”

The approval of the Domestication Proposal is a condition to the closing of the transactions contemplated by the Business Combination Agreement. The approval of the Domestication Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as a vote cast at the Special Meeting. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Domestication Proposal.

Q: HOW WILL THE DOMESTICATION AFFECT MY PUBLIC SHARES, PUBLIC WARRANTS AND UNITS?

A: On the effective date of the Domestication, (a) each outstanding Class A ordinary share will automatically convert into one share of Fathom Class A common stock, (b) each outstanding Class B ordinary share will

20

automatically convert into one share of Fathom Class C common stock (and subsequently at the closing of the Business Combination, each outstanding share of Fathom Class C common stock will automatically convert into Fathom Class A common stock prior to the pro rata forfeiture by the Altimar II Founders of an aggregate of 2,587,500 of their Class A common stock pursuant to the Forfeiture and Support Agreement as described herein) and (c) the outstanding warrants to purchase Class A ordinary shares will automatically become exercisable for shares of Fathom Class A common stock. At a moment in time after the effectiveness of the Domestication and before the closing of the Business Combination, each outstanding unit of Altimar II (each of which consists of one share of Altimar II Class A ordinary shares and one-fourth of one warrant to purchase one share of Altimar II Class A ordinary shares) will be separated into its component common stock and warrant. Such warrants will become exercisable into shares of Class A common stock any time after the later of the one year following the completion of Altimar II’s IPO and 30 days following the completion of the Business Combination.

Q: WHAT HAPPENS TO THE FUNDS DEPOSITED IN THE TRUST ACCOUNT AFTER CONSUMMATION OF THE BUSINESS COMBINATION?

A: The net proceeds of Altimar II’s initial public offering, together with funds raised from the sale of Private Placement Warrants simultaneously with the consummation of Altimar II’s initial public offering, was placed in the Trust Account immediately following Altimar II’s initial public offering. After consummation of the Business Combination, the funds in the Trust Account will be used to pay holders of the Class A ordinary shares who exercise redemption rights, to pay fees and expenses incurred in connection with the Business Combination (including aggregate fees of approximately $12,075,000 as deferred underwriting commissions related to Altimar II’s initial public offering) and, together with the proceeds of the PIPE Investment, to pay the Closing Cash Consideration.

Q: WHAT ARE THE U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE DOMESTICATION?

A: As discussed more fully under “Material U.S. Federal Income Tax Considerations” below, it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison LLP that the Domestication should qualify as a reorganization within the meaning of Section 368(a)(l)(F) of the Code. However, due to the absence of direct guidance on the application of Section 368(a)(1)(F) to a statutory conversion of a corporation holding only investment-type assets such as Altimar II, this result is not entirely clear. Assuming that the Domestication so qualifies, U.S. holders (as defined in “Material U.S. Federal Income Tax Considerations — U.S. Holders” below) of Altimar II ordinary shares will be subject to Section 367(b) of the Code and, as a result:

• A U.S. holder of Altimar II ordinary shares whose Altimar II ordinary shares have a fair market value of less than $50,000 at the time of the Domestication should not recognize any gain or loss and generally should not be required to include any part of Altimar II’s earnings in income;

• A U.S. holder of Altimar II ordinary shares whose Altimar II ordinary shares have a fair market value of $50,000 or more on the date of the Domestication, but who at the time of the Domestication owns (actually and constructively) less than 10% of the total combined voting power of all classes of Altimar II ordinary shares entitled to vote and less than 10% of the total value of all classes of Altimar II ordinary shares will generally recognize gain (but not loss) as a result of the Domestication. As an alternative to recognizing gain, such U.S. holders may file an election to include in income as a dividend earnings and profits (as defined in the U.S. Treasury regulations (“Treasury Regulations”) under Section 367 of the Code) attributable to its Altimar II ordinary shares provided certain other requirements are satisfied. Altimar II does not expect that Altimar II’s cumulative earnings and profits will be material at the time of the Domestication.

• A U.S. holder of Altimar II ordinary shares who at the time of the Domestication owns (actually and constructively) 10% or more of the total combined voting power of all classes of Altimar II ordinary shares or 10% of the total value of all classes of Altimar II shares entitled to vote will

21

generally be required to include in income as a dividend earnings and profits (as defined in the Treasury Regulations under Section 367 of the Code) attributable to its Altimar II ordinary shares. Altimar II does not expect that Altimar II’s cumulative earnings and profits will be material at the time of domestication. If Altimar II were to be treated as a PFIC for U.S. federal income tax purposes, certain U.S. holders may be subject to adverse tax consequences as a result of the Domestication. Pursuant to a start-up exception, a corporation will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if (i) no predecessor of the corporation was a PFIC; (ii) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year; and (iii) the corporation is not in fact a PFIC for either of those two years. Altimar II believes, although subject to uncertainty, that Altimar II’s 2021 taxable year may be the start-up year and that Altimar II may not be treated as a PFIC for 2021. The application of the start-up exception will depend, in part, on whether the Domestication is consummated in 2021. In addition, the application of the start-up exception to the present transaction involves the application of complicated rules with respect to which there is no clear authority. Accordingly, there can be no assurance with respect to Altimar II’s status as a PFIC for 2021. All holders are urged to consult their tax advisors concerning the application of the PFIC rules to Altimar II under such holder’s particular circumstances, including the potential to make a “qualified electing fund” election or a protective “qualified electing fund” election. The requirement to qualify for the start-up exception and the potential application of the PFIC rules to the Domestication are discussed more fully under “Material U.S. Federal Income Tax Considerations — U.S. Holders — PFIC Considerations”.

Additionally, the Domestication may cause non-U.S. holders (as defined in “Material U.S. Federal Income Tax Considerations — Non-U.S. Holders” below) to become subject to U.S. federal income withholding taxes on any dividends in respect of such non-U.S. holder’s Fathom common stock (or warrants) subsequent to the Domestication.

The tax consequences of the Domestication are complex and will depend on a holder’s particular circumstances. All holders are strongly urged to consult their tax advisor for a full description and understanding of the tax consequences of the Domestication, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws. For a more complete discussion of the U.S. federal income tax considerations of the Domestication, see “Material U.S. Federal Income Tax Considerations”.

Q: HOW DOES THE SPONSOR INTEND TO VOTE ON THE SHAREHOLDER PROPOSALS?

A: The Sponsor owns of record and is entitled to vote an aggregate of approximately 20% of the outstanding shares of Altimar ordinary shares. The Sponsor has agreed to vote any founder shares and any Class A ordinary shares held by it as of the record date in favor of the Shareholder Proposals. See “The Business Combination Agreement — Related Agreements — Forfeiture and Support Agreement”. In addition, each of Sponsor and the other Altimar II Founders agreed, among other things, (i) from the date of the Business Combination Agreement until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, to not redeem any Class A ordinary shares (or, if applicable, shares of Class A common stock) held by it and (ii) prior to the consummation of Business Combination or the termination of the Business Combination Agreement, to vote or cause to be voted, all of the Altimar II shares beneficially owned by Sponsor or such other Founder Holder, at every meeting of the shareholders of Altimar II at which such matters are considered and at every adjournment or postponement thereof: (1) in favor of (A) the Business Combination and the Business Combination Agreement and the other transactions contemplated thereby (including any proposals recommended by Altimar II’s Board of Directors in connection with the Business Combination) and (B) any proposal to adjourn or postpone such meeting of shareholders to a later date if there are not sufficient votes to approve the Business Combination; (2) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of Altimar II under the Business Combination

22

Agreement; and (3) against (A) any proposal or offer from any person concerning (I) a merger, consolidation, liquidation, recapitalization, share exchange or other business combination transaction involving Altimar II, or (II) the issuance or acquisition of shares of capital stock or other Altimar II equity securities (other than as contemplated or permitted by the Business Combination Agreement); and (B) any action, proposal, transaction or agreement that would reasonably be expected to (x) impede the fulfillment of Altimar II’s conditions under the Business Combination Agreement or change in any manner the voting rights of any class of Altimar II’s shares or (y) result in a breach of any covenant, representation or warranty or other obligation or agreement of Sponsor or any of the other Altimar II Founders contained in the Forfeiture and Support Agreement. See also “Certain Relationships and Related Party Transactions — Forfeiture and Support Agreement.”

Q: WHAT CONSTITUTES A QUORUM AT THE SPECIAL MEETING?

A: The holders of a majority of the voting power of the issued and outstanding Altimar II ordinary shares entitled to vote at the Special Meeting must be present, in person or virtually or represented by proxy, at the Special Meeting to constitute a quorum and in order to conduct business at the Special Meeting. Abstentions and broker non-votes will be counted as present for the purpose of determining a quorum. The holders of the founder shares, who currently own approximately 20% of the issued and outstanding shares of Altimar II ordinary shares, will count towards this quorum. In the absence of a quorum, the chairman of the Special Meeting has power to adjourn the Special Meeting. As of the record date for the Special Meeting, holders of                Altimar II ordinary shares would be required to be present to achieve a quorum.

Q: WHAT VOTE IS REQUIRED TO APPROVE EACH PROPOSAL AT THE SPECIAL MEETING?

A: The Business Combination Proposal: The approval of the Business Combination Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Altimar II shareholders must approve the Business Combination Proposal in order for the Business Combination to occur. If Altimar II shareholders fail to approve the Business Combination Proposal, the Business Combination will not occur. Pursuant to the IPO Letter Agreement and as further discussed in the section entitled “The Business Combination Agreement — Related Agreements — Forfeiture and Support Agreement,” the Sponsor and the other Altimar II Founders have agreed to vote shares representing approximately 20% of the aggregate voting power of the Altimar II ordinary shares in favor of the Business Combination Proposal.

The Domestication Proposal: The approval of the Domestication Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Domestication Proposal is conditioned on the approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal is not approved, the Domestication Proposal will have no effect, even if approved by Altimar II’s Public Shareholders. Pursuant to the IPO Letter Agreement and the Forfeiture and Support Agreement, the Sponsor and the other Altimar II Founders have agreed to vote shares representing approximately 20% of the aggregate voting power of the Altimar II ordinary shares in favor of the Domestication Proposal. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Domestication Proposal.

The Organizational Documents Proposal: The approval of the Organizational Documents Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Organizational Documents Proposal is conditioned on the approval of the Domestication Proposal, and, therefore, also conditioned on approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal or the Domestication Proposal is not approved, the Organizational Documents Proposal will have no effect, even if approved by Altimar II’s Public

23

Shareholders. Pursuant to the Forfeiture and Support Agreement, the Sponsor and the other Altimar II Founders have agreed to vote shares representing approximately 20% of the aggregate voting power of the Altimar II ordinary shares in favor of the Organizational Documents Proposal. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Organizational Documents Proposal.

The Advisory Charter Proposals: The approval of any of the Advisory Charter Proposals is not otherwise required by Cayman Islands law or Delaware law separate and apart from the Organizational Documents Proposal, but pursuant to SEC guidance, Altimar II is required to submit these provisions to its stockholders separately for approval. However, the stockholder votes regarding these proposals are advisory votes, and are not binding on Altimar II or the Altimar II Board (separate and apart from the approval of the Organizational Documents Proposal). Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Proposals (separate and apart from approval of the Organizational Documents Proposal).

The Stock Issuance Proposal: The approval of the Stock Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Stock Issuance Proposal is conditioned on the approval of the Organizational Documents Proposal, and, therefore, also conditioned on approval of the Domestication Proposal and the Business Combination Proposal. Therefore, if any of the Business Combination Proposal, the Domestication Proposal or the Organizational Documents Proposal is not approved, the Stock Issuance Proposal will have no effect, even if approved by Altimar II’s Public Shareholders. Pursuant to the IPO Letter Agreement and the Forfeiture and Support Agreement, the Sponsor and the other Altimar II Founders have agreed to vote shares representing approximately 20% of the aggregate voting power of the Altimar II ordinary shares in favor of the Stock Issuance Proposal.

The Business Combination Issuance Proposal: The approval of the Business Combination Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Business Combination Issuance Proposal is conditioned on the approval of the Stock Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal and the Equity Incentive Plan Proposal. Therefore, if any of those Shareholder Proposals is not approved, the Business Combination Issuance Proposal will have no effect, even if approved by Altimar II’s Public Shareholders. Pursuant to the IPO Letter Agreement and the Forfeiture and Support Agreement, the Sponsor and the other Altimar II Founders have agreed to vote shares representing approximately 20% of the aggregate voting power of the Altimar II ordinary shares in favor of the Business Combination Issuance Proposal.

The Equity Incentive Plan Proposal: The approval of the Equity Incentive Plan Proposal requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Equity Incentive Plan Proposal is conditioned on the approval of the Business Combination Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposals and Stock Issuance Proposal. Therefore, if any of those proposals is not approved, the Equity Incentive Plan Proposal will have no effect, even if approved by Altimar II’s Public Shareholders.

The ESPP Proposal: The approval of the ESPP Proposal requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The ESPP Proposal is conditioned on the approval of the Business Combination Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposals and Stock

The Adjournment Proposal: The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Adjournment Proposal is not conditioned upon any other Shareholder Proposal.

Q: DO ANY OF ALTIMAR II’S DIRECTORS OR OFFICERS HAVE INTERESTS IN THE BUSINESS COMBINATION THAT MAY DIFFER FROM OR BE IN ADDITION TO THE INTERESTS OF ALTIMAR II SHAREHOLDERS?

A: Altimar II’s executive officers and certain non-employee directors may have interests in the Business Combination that may be different from, or in addition to, the interests of Altimar II’s shareholders generally. The Altimar II board of directors was aware of and considered these interests to the extent such interests existed at the time, among other matters, in approving the Business Combination Agreement and in recommending that the Business Combination Agreement and the transactions contemplated thereby be approved by the shareholders of Altimar II . See “The Business Combination Proposal — Interests of Altimar II Directors and Officers in the Business Combination.”

For additional information regarding pre-existing relationships between certain of the parties to the Business Combination Agreement and certain of their affiliates, see “Risk Factors — Risks Related to the Business Combination and Altimar II — Pre-existing relationships between participants in the Business Combination and the related transactions or their affiliates could give rise to actual or perceived conflicts of interest in connection with the Business Combination.”

Q: WHAT DO I NEED TO DO NOW?

A: After carefully reading and considering the information contained in this proxy statement/prospectus, please submit your proxies as soon as possible so that your shares will be represented at the Special Meeting. Please follow the instructions set forth on the proxy card or on the voting instruction form provided by your broker, bank or other nominee if your shares are held in the name of your broker, bank or other nominee.

Q: HOW DO I VOTE?

A: If you are a shareholder of record of Altimar II as of                , 2021 (the “record date”) you may submit your proxy before the Special Meeting in any of the following ways, if available:

• use the toll-free number shown on your proxy card;

• visit the website shown on your proxy card to vote via the Internet; or

• complete, sign, date and return the enclosed proxy card in the enclosed postage-paid envelope.

If you are a shareholder of record of Altimar II as of the record date, you may also cast your vote at the Special Meeting.

If your shares are held in “street name” through a broker, bank or other nominee, your broker, bank or other nominee will send you separate instructions describing the procedure for voting your shares. “Street name” shareholders who wish to vote at the Special Meeting will need to obtain a proxy form from their broker, bank or other nominee.

Q: WHEN AND WHERE IS THE SPECIAL MEETING?

A: The Special Meeting will be held on                , 2021, at                 local time. For the purposes of Altimar II’s Amended and Restated Memorandum and Articles of Association, the physical place of the meeting will

25

be Boundary Hall, Cricket Square, Grand Cayman, KY1-1102, Cayman Islands. In light of the novel coronavirus pandemic and to support the well-being of Altimar II’s shareholders, directors and officers, Altimar II encourages you to use remote methods of attending the Special Meeting or to attend via proxy. You may attend the Special Meeting and vote your shares electronically during the Special Meeting via live webcast by visiting https://www.cstproxy.com/altimarii/2021. You will need the meeting control number that is printed on your proxy card to enter the Special Meeting. You may also attend the meeting telephonically by dialing +1 877-770-3647 (within the U.S. and Canada and toll-free) or +1 312-780-0854 (outside of the U.S. and Canada, standard rates apply). All Altimar II shareholders as of the record date, or their duly appointed proxies, may attend the Special Meeting.

Q: IF MY SHARES ARE HELD IN “STREET NAME” BY A BROKER, BANK OR OTHER NOMINEE, WILL MY BROKER, BANK OR OTHER NOMINEE VOTE MY SHARES FOR ME?

A: If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares. Please follow the voting instructions provided by your broker, bank or other nominee. Please note that you may not vote shares held in “street name” by returning a proxy card directly to Altimar II or by voting at the Special Meeting unless you provide a “legal proxy”, which you must obtain from your broker, bank or other nominee. In addition to such legal proxy, if you plan to attend the Special Meeting, but are not a shareholder of record because you hold your shares in “street name”, please have evidence of your beneficial ownership of your shares (e.g., a copy of a recent brokerage statement showing the shares) and valid photo identification with you at the Special Meeting.

Under the rules of the NYSE, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that the NYSE determines to be “non-routine” without specific instructions from the beneficial owner. It is expected that all of the Shareholder Proposals are “non-routine” matters. Broker non-votes occur when a broker or nominee is not instructed by the beneficial owner of shares to vote on a particular Shareholder Proposal for which the broker does not have discretionary voting power.

If you are an Altimar II shareholder holding your shares in “street name” and you do not instruct your broker, bank or other nominee on how to vote your shares, your broker, bank or other nominee will not vote your shares on the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal or the Adjournment Proposal. Such abstentions and broker non-votes will have no effect on the vote count for any of the proposals.

Q: WHAT IF I ATTEND THE SPECIAL MEETING AND ABSTAIN OR DO NOT VOTE?

A: For purposes of the Special Meeting, an abstention occurs when a shareholder attends the meeting and does not vote or returns a proxy with an “abstain” vote.

If you are an Altimar II shareholder that attends the Special Meeting and fails to vote on the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal or the Adjournment Proposal, or if you respond to such proposals with an “abstain” vote, your failure to vote or “abstain” vote in each case will have no effect on the vote count for such proposals.

26

Q: WHAT WILL HAPPEN IF I RETURN MY PROXY CARD WITHOUT INDICATING HOW TO VOTE?

A: If you sign and return your proxy card without indicating how to vote on any particular Shareholder Proposal, the Altimar II shares represented by your proxy will be voted as recommended by the Altimar II board of directors with respect to that Shareholder Proposal.

Q: MAY I CHANGE MY VOTE AFTER I HAVE DELIVERED MY PROXY OR VOTING INSTRUCTION CARD?

A: Yes. You may change your vote at any time before your proxy is voted at the Special Meeting. You may do this in one of three ways:

• filing a notice with Altimar II or its proxy solicitor;

• mailing a new, subsequently dated proxy card; or

• by attending the Special Meeting and electing to vote your shares.

If you are a shareholder of record of Altimar II and you choose to send a written notice or to mail a new proxy, you must submit your notice of revocation or your new proxy to Altimar II, 40 West 57th Street, 33rd Floor, New York, NY, 10019 and it must be received at any time before the vote is taken at the Special Meeting. Any proxy that you submitted may also be revoked by submitting a new proxy by mail, or online or by telephone, not later than 5:00 p.m. New York City time on                  , 2021, or by voting at the Special Meeting. Simply attending the Special Meeting will not revoke your proxy. If you have instructed a broker, bank or other nominee to vote your shares of Altimar II ordinary shares, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your vote.

Q: WHAT HAPPENS IF I FAIL TO TAKE ANY ACTION WITH RESPECT TO THE SPECIAL MEETING?

A: If you fail to take any action with respect to the Special Meeting and the Business Combination is approved by shareholders and consummated, you will continue to be a shareholder of Altimar II. Failure to take any action with respect to the Special Meeting will not affect your ability to exercise your redemption rights. If you fail to take any action with respect to the Special Meeting and the Business Combination is not approved, you will continue to be a shareholder of Altimar II while Altimar II searches for another target business with which to complete a business combination.

Q: WHAT SHOULD I DO IF I RECEIVE MORE THAN ONE SET OF VOTING MATERIALS?

A: Shareholders may receive more than one set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered under more than one name, you will receive more than one proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares.

Q: WHOM SHOULD I CONTACT IF I HAVE ANY QUESTIONS ABOUT THE PROXY MATERIALS OR VOTING?

A: If you have any questions about the proxy materials, need assistance submitting your proxy or voting your shares or need additional copies of this proxy statement/prospectus or the enclosed proxy card, you should contact Innisfree M&A Incorporated, the proxy solicitor for Altimar II, toll-free at (817) 750-8129 (banks and brokers call (212) 750-5833).

Altimar II will issue to Continuing Fathom Unitholders for cash at par value a number of shares of Class B common stock equal to the number of New Fathom Units held by the Continuing Fathom Unitholders. Altimar II’s other shareholders will hold Class A common stock of the combined company.

The Private Placement

In connection with entering into the Business Combination Agreement, on July 15, 2021, Altimar II and Fathom OpCo entered into the Original PIPE Subscription Agreements with certain institutional and other accredited investors (the “Original PIPE Investors”), pursuant to which, among other things, the Original PIPE Investors party thereto agreed to purchase an aggregate of 8,000,000 shares of Class A common stock following the Domestication and immediately prior to the Closing at a cash purchase price of $10.00 per share, resulting in aggregate proceeds of $80.0 million (the “Original PIPE Investment”).

The Original PIPE Subscription Agreements contain customary representations, warranties, covenants and agreements of Altimar II, Fathom OpCo and the Original PIPE Investors and are subject to customary closing conditions (including, without limitation, that there is no amendment or modification to the Business Combination Agreement that is material and adverse to the Original PIPE Investors) and termination rights (including a termination right if the transactions contemplated by the Original PIPE Subscription Agreements have not been consummated by December 31, 2021, other than as a result of breach by the terminating party). The Original PIPE Investments are expected to close immediately prior to the Closing.

On November 16, 2021, Altimar II and Fathom OpCo entered into a Backstop Agreement with the CORE Investors (the “Backstop Investors”) pursuant to which the Backstop Investors agreed to purchase an aggregate of up to 1,000,000 shares of Class A common stock following the Domestication and immediately prior to the Closing at a cash purchase price of $10.00 per share (the “CORE Backstop Agreement”), resulting in aggregate proceeds of up to $10.0 million (the “Backstop Investment”) only if (i) the Available Cash Condition is not satisfied and (ii) the Available Cash Shortfall does not exceed $10.0 million and subject to other the terms and conditions of the CORE Backstop Agreement.

If the conditions to the consummation of the Backstop Investment are triggered, the Backstop Investment is expected to close immediately prior to the Closing, subject to the terms and conditions of the CORE Backstop Agreement.

There are important differences between the rights of holders of shares of Class A common stock and holders of Altimar II Class A ordinary shares. See “The Domestication Proposal—Comparison of Corporate Governance and Shareholders” for a discussion of the different rights associated with holding these securities. In addition, the Altimar II Class A ordinary shares were originally sold in the Altimar II IPO as a component of the Altimar II units for $10.00 per unit. The Altimar II units consist of one Class A ordinary share and one-fourth of one redeemable Altimar II warrant.

31

Consideration to be Received in the Business Combination

The total consideration to be paid to the Fathom Blocker Owners and the Continuing Fathom Unitholders (each as defined herein), including CORE Industrial Partners Fund I, LP, at the Closing shall equal the aggregate of:

(a) (i) All the cash proceeds from the Trust Account established for the purpose of holding the net proceeds of Altimar II’s initial public offering, net of any amounts paid to Altimar II’s shareholders that exercise their redemption rights in connection with the Business Combination, together with the proceeds from the PIPE Investment (as defined herein) (the “Available Cash Amount”), (ii) minus $10,000,000 to be contributed by Altimar II to the balance sheet of Fathom OpCo, (iii) minus $20,000,000 to be used to pay down certain indebtedness of Fathom OpCo, (iv) minus certain transaction expenses of Fathom OpCo and Altimar II, which include fees and expenses of various advisors, transfer taxes, employee transaction bonuses, and filing and listing fees (the “Closing Cash Consideration”); and

(b) A number of shares of Class A common stock and newly issued Class A units of Fathom OpCo (the “New Fathom Units”) (together with one share of Class B common stock to be issued at par value for cash in respect of each New Fathom Units), to be allocated as set forth on the Allocation Schedule, in an aggregate number (rounded up to the nearest whole share) equal to (a) the quotient of (i) the result of (A) $1,200,000,000 minus (B) the Closing Cash Consideration divided by (b) $10.00 plus (ii) 1,293,750 in each case of clauses (a) and (b), to be allocated as set forth on the Allocation Schedule (the “Closing Seller Equity Consideration”).

For more information, see the section entitled “The Business Combination Agreement—Consideration to be Received in the Business Combination.”

Earnout

In addition to the Closing Seller Equity Consideration, an aggregate of 9,000,000 shares of Class A common stock and New Fathom Units (the “Earnout Shares”) will be issued in three equal tranches of 3,000,000 shares and allocated in accordance with the Allocation Schedule, with each tranche vesting at each of the following share price thresholds: $12.50, $15.00 and $20.00, in each case subject to the vesting and forfeiture provisions set forth in the Investor Rights Agreement (as defined herein) and Fathom’s Amended and Restated Limited Liability Company Agreement (the “Fathom Operating Agreement”). The earnout period will be five years from the date of the closing of the Business Combination. The achievement of the price threshold will be determined based on a VWAP for 20 trading days within any 30-trading day period or a change of control transaction of Fathom that implies the same per share valuation as the applicable price threshold.

For more information, see the section entitled “The Business Combination Agreement — Earnout.”

Allocation Schedule

The methodology to be followed in the Allocation Schedule at the Closing will provide for the payment of approximately $             of the Closing Cash Consideration to direct and indirect holders of outstanding preferred units of Fathom OpCo (including accrued but unpaid preferred distributions thereon), and will allocate the balance of the Closing Cash Consideration and the total Closing Seller Equity Consideration to direct and indirect holders of outstanding common units of Fathom OpCo, on a pro rata basis in accordance with the number of outstanding common units held. The Earnout Shares will be allocated in accordance with the Allocation Schedule to the direct and indirect holders of outstanding common units of Fathom OpCo on a pro rata basis in accordance with the number of outstanding common units held. The portion of the Closing Cash Consideration to be paid to direct and indirect holders of outstanding preferred units of Fathom OpCo as described above assumes, for illustration, the inclusion of accrued preferred distributions through                 , 2021. The total amount to be paid to the holders of preferred units will vary to reflect the accrued preferred distributions as of the Closing Date.

32

Altimar II Extraordinary Meeting and the Proposals

The Special Meeting will be held at                  a.m., Eastern Time, on,                  2021. For the purposes of complying with Altimar II’s Amended and Restated Memorandum and Articles of Association, the physical place of the meeting will be Boundary Hall, Cricket Square, Grand Cayman, KY1-1102, Cayman Islands. In light of the novel coronavirus pandemic and to support the well-being of Altimar II’s shareholders, directors and officers, Altimar II encourages you to use remote methods of attending the Special Meeting or to attend via proxy. You may attend the Special Meeting and vote your shares electronically during the Special Meeting via live webcast by visiting https://www.cstproxy.com/altimarii/2021. You will need the meeting control number that is printed on your proxy card to enter the Special Meeting. You may also attend the meeting telephonically by dialing: +1 877-770-3647 (within the U.S. and Canada and toll-free) or +1 312-780-0854 (outside of the U.S. and Canada, standard rates apply). At the Special Meeting, Altimar II’s shareholders will be asked to approve the Business Combination Proposal, the Domestication Proposal, Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal (if necessary).

The Altimar II board of directors has fixed the close of business on                  (the “record date”) as the record date for determining the holders of Altimar II ordinary shares entitled to receive notice of and to vote at the Special Meeting. As of the record date, there were                  shares of Altimar II Class A ordinary shares and                  shares of Altimar II Class B ordinary shares outstanding and entitled to vote at the Special Meeting. Each share of Altimar II ordinary shares entitles the holder to one vote at the Special Meeting on each proposal to be considered at the Special Meeting. As of the record date, the Sponsor and Altimar II’s directors and officers and their affiliates owned and were entitled to vote                  shares of Altimar II ordinary shares, representing approximately 20% of the shares of Altimar II ordinary shares outstanding on that date. Altimar II currently expects that the Sponsor and its directors and officers will vote their shares in favor of the Shareholder Proposals and, pursuant to the IPO Letter Agreement and the Forfeiture and Support Agreement, the Sponsor and directors and officers have agreed to do so. As of the record date, Fathom did not beneficially hold any shares of Altimar II ordinary shares.

A majority of the voting power of the issued and outstanding Altimar II ordinary shares entitled to vote at the Special Meeting must be present, in person or virtually or represented by proxy, at the Special Meeting to constitute a quorum and in order to conduct business at the Special Meeting.

Approval of the Business Combination Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Approval of the Domestication Proposal, the Organizational Documents Proposal and the Advisory Charter Proposals require a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Domestication Proposal and the Organizational Documents Proposal. Approval of the Advisory Charter Proposals, Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal, the ESPP Proposal and the Adjournment Proposal (if necessary) each requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting.

The Business Combination is conditioned upon the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal and the ESPP Proposal subject to the terms of the Business Combination Agreement. The Business Combination is not conditioned on the Advisory Charter Proposals or the Adjournment Proposal. If the Business Combination Proposal is not approved, the other Shareholder Proposals (except the Adjournment Proposal) will not be presented to the shareholders for a vote.

33

Recommendation of Altimar II’s Board of Directors

Altimar II’s board of directors has unanimously determined that the Business Combination Proposal is in the best interests of Altimar II and its shareholders, has unanimously approved the Business Combination Proposal, and unanimously recommends that shareholders vote “FOR” the Business Combination Proposal, “FOR” the Domestication Proposal, “FOR” the Organizational Documents Proposal, “FOR” each of the Advisory Charter Proposals, “FOR” the Stock Issuance Proposal, “FOR” the Business Combination Issuance Proposal, “FOR” for the Equity Incentive Plan Proposal, “FOR” the ESPP Proposal and “FOR” the Adjournment Proposal, in each case, if presented to the Special Meeting.

Altimar II ’s Board of Directors’ Reasons for Approval of the Business Combination

On July 15, 2021, the Board unanimously (i) approved the signing of the Business Combination Agreement and the transactions contemplated thereby and (ii) directed that the Business Combination Agreement, related transaction documentation and other Shareholder Proposals be submitted to Altimar II’s shareholders for approval and adoption, and recommended that Altimar II’s shareholders approve and adopt the Business Combination Agreement, related transaction documentation and such other Shareholder Proposals. In light of the number and wide variety of factors considered in connection with its evaluation of the Business Combination, the Board did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination and supporting its decision. The Altimar II board of directors did not seek to obtain a third-party valuation or fairness opinion in connection with their determination to approve the Business Combination. The Altimar II board of directors viewed its decision as being based on all of the information available and the factors presented and considered by it. In addition, individual directors may have given different weight to different factors. For more information, see the section entitled “ The Business Combination Agreement—Altimar Board of Directors’ Reasons for the Approval of the Business Combination.” This explanation of Altimar II’s reasons for the Business Combination and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Statement Regarding Forward-Looking Statements.”

Consistent with its investment philosophy and strategy, Altimar II planned to identify a high-quality business run by exceptional teams pursuing growth and large market opportunities. These criteria were not intended to be exhaustive, and the evaluation relating to the merits of Altimar II’s initial business combination would be based, to the extent relevant, on these general guidelines as well as other considerations, factors and criteria that Altimar II’s management team deemed relevant. In considering the Business Combination with Fathom OpCo, the Board concluded that it met all of the above criteria.

The Board also gave consideration to certain risks related to the Business Combination, which are described in this proxy statement/prospectus under the caption “Risk Factors”.

The parties will use their respective reasonable best efforts to promptly file all notices, reports and other documents required to be filed by such party with any governmental authority with respect to the Business Combination, and to submit promptly any additional information requested by any such governmental authority. The parties will use their respective reasonable best efforts to promptly obtain all authorizations, approvals, clearances, consents, actions or non-actions of any governmental authority in connection with the applicable filings, applications or notifications. Each party will promptly inform the other parties of any material communication between itself or its representatives and any governmental authority regarding the Business Combination. If a party or any of its affiliates receives any request for supplemental information or documentary material from any governmental authority with respect to the Business Combination, then the party, to the extent necessary and advisable, shall provide a reasonable response to such request as promptly as reasonably practicable.

34

Additionally, each party’s obligation to complete the Business Combination is subject to the waiting period (and any extension thereof) applicable to the consummation of the Business Combination under the Hart–Scott–Rodino Antitrust Improvements Act of 1976 having expired or been terminated.

Conditions to Closing

The Closing is subject to certain customary conditions, including, among other things: (i) the approval of the Business Combination and other matters by Altimar II’s shareholders; (ii) the expiration or termination of any applicable waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, and receipt of certain additional regulatory approvals; (iii) the Available Cash Amount (as defined herein) equaling no less than $90,000,000 at the Closing (after giving effect to the receipt of proceeds from the Backstop Investment, if applicable); (iv) (x) fundamental representations and warranties (which includes Organization, Due Authorization, Holding Company; Ownership and Brokers’ Fees) bring down conditions to an “all material respects” standard, (y) general representations and warranties bring down conditions to a “material adverse effect” standard and (z) capitalization representation bring down condition to a “de minimis” standard; (v) covenant bring down conditions to an “all material respects” standard; (vi) the absence of a material adverse effect on the respective parties; and (vii) the effectiveness of this registration statement and the listing of Altimar II Class A common stock to be issued in the Business Combination on the New York Stock Exchange (“NYSE”). To the extent permitted by law, the conditions in the Business Combination Agreement may be waived by the parties thereto.

Termination

The Business Combination Agreement may be terminated by Altimar II or Fathom OpCo under certain circumstances, including, among others, (i) by mutual written consent of Fathom OpCo and Altimar II, (ii) by Fathom OpCo or Altimar II if the Closing has not occurred on or before December 31, 2021 (the “Outside Date”), (iii) by Fathom OpCo or Altimar II in the case of material uncured breach by the other party to the Business Combination Agreement (subject to notice and an opportunity to cure, if curable), (iv) by Fathom OpCo if, prior to obtaining approval of Altimar II’s shareholders, Altimar II’s board of directors made a change in recommendation and (v) by Fathom OpCo or Altimar II if Altimar II has not obtained the required approval of its shareholders.

Redemption Rights

Public Shareholders may seek to redeem the public shares that they hold, regardless of whether they vote for the Business Combination, against the Business Combination or do not vote in relation to the Business Combination. Any Public Shareholder may request redemption of their public shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest, less income taxes payable, divided by the number of then issued and outstanding public shares. If a holder properly seeks redemption as described in this section and the Business Combination is consummated, the holder will no longer own these shares following the Business Combination.

Notwithstanding the foregoing, a Public Shareholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act) will be restricted from seeking redemption rights with respect to 15% or more of the shares of the public shares. Accordingly, if a Public Shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

Altimar II’s initial shareholders will not have redemption rights with respect to any ordinary shares owned by them, directly or indirectly.

35

You will be entitled to receive cash for any public shares to be redeemed only if you:

(i) (a) hold public shares or (b) hold units and you elect to separate your units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii) prior to                 p.m., Eastern Time, on                  , 2021, (a) submit a written request to the transfer agent that Altimar II redeem your public shares for cash and (b) deliver your share certificates for your public shares (if any) to the transfer agent, physically or electronically through DTC.

An Altimar II shareholder may not withdraw a redemption request once submitted to Altimar II unless the board of directors of Altimar II determines (in its sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). Furthermore, if a holder of a public share delivers its certificate (if any) and other redemption forms in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request that Altimar II permit the withdrawal of the redemption request and instruct its transfer agent to return the certificate (physically or electronically). The holder can make such request by contacting the transfer agent, at the address or email address listed in this proxy statement/prospectus.

If the Business Combination is not approved or completed for any reason, then Altimar II’s Public Shareholders who elected to exercise their redemption rights will not be entitled to redeem their shares. In such case, Altimar II will promptly return any shares previously delivered by public holders.

If a Public Shareholder exercises its redemption rights, then it will be exchanging its redeemed public shares for cash and will no longer own those public shares. You will be entitled to receive cash for your public shares only if you properly exercise your right to redeem the public shares that you will hold upon the Domestication, no later than the close of the vote on the Business Combination Proposal, and deliver your ordinary shares (either physically or electronically) to the transfer agent, prior to                                  5:00 p.m., Eastern Time, on                 , 2021, and the Business Combination is consummated.

In order for Public Shareholders to exercise their redemption rights in respect of the Business Combination, Public Shareholders must properly exercise their right to redeem the public shares that you will hold upon the Domestication no later than the close of the vote on the Business Combination Proposal and deliver their ordinary shares (either physically or electronically) to the transfer agent, prior to                                  5:00 p.m., Eastern Time on                 , 2021. Therefore, the exercise of redemption rights occurs prior to the Domestication. For the purposes of Article 49.3 of the Amended and Restated Memorandum and Articles of Association of Altimar II and Cayman Islands law, the exercise of redemption rights shall be treated as an election to have such public shares repurchased for cash and references in this proxy statement/prospectus shall be interpreted accordingly. Immediately following the Domestication and the consummation of the Business Combination, Public Shareholders who properly exercised their redemption rights in respect of their public shares shall be paid.

No Appraisal Rights

Altimar II’s shareholders will not have appraisal rights under Cayman Islands law or otherwise in connection with the Business Combination Proposal or the other Shareholder Proposals.

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person. Altimar II has engaged Innisfree M&A Incorporated to assist in the solicitation of proxies. If a shareholder grants a proxy, it may still vote its shares in person if it revokes its proxy before the Special Meeting. A shareholder also may change its vote by submitting a later-dated proxy as described in the section entitled “The Extraordinary General Meeting — Revoking Your Proxy.”

36

Interests of Altimar II Directors and Officers in the Business Combination

In considering the recommendation of the board of directors of Altimar II to vote in favor of approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal and the other Shareholder Proposals, shareholders should keep in mind that the Sponsor and certain members of the board of directors and officers of Altimar II and the Sponsor, including its directors and officers, have interests in such Shareholder Proposals that are different from, or in addition to, those of Altimar II’s shareholders generally. In particular:

• If Altimar II does not consummate a business combination by February 9, 2023 (unless such date is extended in accordance with the Amended and Restated Memorandum and Articles of Association), it would cease all operations except for the purpose of winding up, redeeming all of the outstanding Class A ordinary shares for cash and, subject to the approval of its remaining shareholders and its board of directors, dissolving and liquidating, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In such event, the 8,625,000 Class B ordinary shares would be worthless because following the redemption of the Class A ordinary shares, Altimar II would likely have few, if any, net assets and because the holders of our Class B ordinary shares have agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Class B ordinary shares if we fail to complete a Business Combination within the required period. Sponsor purchased the Class B ordinary shares prior to our initial public offering for approximately $0.003 per share. The 4,770,000 shares of Class A common stock that the Altimar II Founders will hold following the Business Combination (excluding the Sponsor Earnout Shares), if unrestricted and freely tradable, would have had aggregate market value of $                                  based upon the closing price of $                                  per share of public share on the NYSE on                 , the record date. Given such shares will be subject to lock-up restrictions, we believe such shares have less value.

• Sponsor purchased 9,900,000 private placement warrants, each exercisable to purchase one Class A ordinary share at $11.50 per share, subject to adjustment, at a price of $1.00 per warrant, and such private placement warrants will expire and be worthless if a business combination is not consummated within 24 months of the consummation of the IPO (unless such date is extended in accordance with the Existing Organizational Documents).

• Altimar II’s existing directors and officers will be eligible for continued indemnification and continued coverage under Altimar II’s directors’ and officers’ liability insurance after the Business Combination.

• In order to protect the amounts held in the Trust Account, Sponsor has agreed that it will be liable to Altimar II if and to the extent any claims by a vendor for services rendered or products sold to Altimar II, or a prospective target business with which Altimar II has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under our indemnity of the underwriters of Altimar II’s initial public offering against certain liabilities, including liabilities under the Securities Act.

• Following consummation of the Business Combination, Sponsor, our officers and directors and their respective affiliates would be entitled to reimbursement for certain reasonable out-of-pocket expenses related to identifying, investigating and consummating an initial business combination, and repayment of any other loans, if any, and on such terms as to be determined by Altimar II from time to time, made by Sponsor or certain of our officers and directors to finance transaction costs in connection with an intended initial business combination. However, if Altimar II fails to consummate a business combination within the required period, Sponsor and Altimar II’s officers and directors and their respective affiliates will not have any claim against the Trust Account for reimbursement.

37

• Pursuant to the Registration Rights Agreement, the Altimar II Founders Holders will have customary registration rights, including demand, shelf and piggy-back rights, subject to cooperation and cut-back provisions, with respect to the shares of Fathom Class A common stock and warrants held by such parties.

• For additional information regarding pre-existing relationships between certain of the parties to the Business Combination Agreement and certain of their affiliates, see “Risk Factors — Risks Related to the Business Combination and Altimar II — Pre-existing relationships between participants in the Business Combination and the related transactions or their affiliates could give rise to actual or perceived conflicts of interest in connection with the Business Combination.”

CORE Investors’ Ability to Influence Fathom Management and Policies Following the Business Combination

Immediately following completion of the Business Combination and assuming no issuance of the Backstop Shares, the CORE Investors will beneficially own approximately 46.1% of our Class A common stock and Class B common stock (or 64.4% assuming maximum redemptions by Altimar II Public Shareholders (and including the Backstop Shares)). The Class A common stock and Class B common stock generally will vote together on matters submitted to a vote of our stockholders, including the election of directors. As a result, the CORE Investors will have the ability to influence our business and affairs through “negative control” rights resulting from their ownership of our Class A common stock and Class B common stock combined with certain supermajority voting provisions of the Proposed Charter and Proposed Bylaws, their general ability to vote on the election of directors to our board and the provisions in the Investor Rights Agreement described below.

With the Business Combination, we will enter into the Investor Rights Agreement with the CORE Investors which will provide for an initial ten-person board of directors, consisting of nine individuals to be designated by the CORE Investors, and one independent director to be mutually agreed by the CORE Investors and the Sponsor. The CORE Investors will have certain continued nomination rights for a number of directors ranging from the majority of the board of directors to one director, while they beneficially own shares of common stock in excess of certain ownership percentage of the amount owned by the CORE Investors at Closing, as determined in accordance with the Investor Rights Agreement. See “The Business Combination Agreement – Related Agreements – Investor Rights Agreement and Registration Rights Agreement” for more details with respect to the Investor Rights Agreement.

Stock Exchange Listing

We expect to list the shares of Fathom Class A common stock and warrants to purchase shares of Class A common stock on the NYSE under the proposed symbols “FATH” and “FATH.WS,” respectively.

Sources and Uses of Funds

The following tables summarize the estimated sources and uses for funding the Business Combination assuming (i) that none of Altimar II’s outstanding Class A ordinary shares are redeemed in connection with the Business Combination (“No Redemptions”) and (ii) that 34.5 million outstanding Class A ordinary shares are redeemed in connection with the Business Combination (representing all the outstanding Public Shares (“Maximum Redemptions”)). The number of Class A ordinary shares redeemable assuming Maximum Redemptions assumes that the per share Redemption Price is $10.00; the actual per share Redemption Price will be equal to the pro rata portion of the Trust Account calculated as of two business days prior to the consummation of the Business Combination.

38

Estimated Sources and Uses (No Redemptions, in millions)

Sources			Uses
Proceeds from Trust Account	$	345	Balance Sheet Contribution	$	10
Original PIPE Investment		80	Closing Cash Consideration		335
			Debt Pay-Down Amount		20
			Transaction Costs		60
Total Sources	$	425	Total Uses	$	425

Estimated Sources and Uses (Maximum Redemptions, in millions)

Sources			Uses
Proceeds from Trust Account	$	0	Balance Sheet Contribution	$	10
Backstop Investment	$	10
Original PIPE Investment		80	Closing Cash Consideration		0
			Debt Pay-Down Amount		20
			Transaction Costs		60
Total Sources	$	90	Total Uses	$	90

The foregoing has been prepared using the following assumptions:

• Assuming No Redemptions: This “minimum scenario” presentation assumes that none of the 34,500,000 Public Shares outstanding as of the record date are redeemed by Altimar II’s Public Shareholders.

• Assuming Maximum Redemptions: This presentation assumes that Altimar II’s Public Shareholders redeem 34,500,000 shares of Altimar II’s Class A ordinary shares. This calculation assumes that the full $90 million in aggregate proceeds are received from the PIPE Investment, including the Backstop Investment, and that the amount in the Trust Account (prior to any redemptions) is equal to $345 million (approximately the amount in the Trust Account as of September 30, 2021), resulting in an aggregate redemption payment (based on an estimated redemption price per share of approximately $10) of $345 million. This scenario results in the following adjustments to the consideration payable at closing:

• Fathom OpCo Owner Consideration: A reduction to the amount of the Closing Cash Consideration of $335 million, such that there will be no Closing Cash Consideration (assuming the Balance Sheet Contribution is $10 million and the Debt Pay-Down Amount is equal to $20 million), and a corresponding increase in the number of shares of Class A common stock and New Fathom Units that comprise the Closing Seller Equity Consideration equal to 33,500,000 (equal to the amount by which Closing Cash Consideration is reduced in this scenario divided by $10), such that the Closing Seller Equity Consideration will be an aggregate number of shares of Class A common stock and Class B common stock equal to 121,293,750.00.

For additional information, including the assumptions underlying the no redemptions and maximum redemptions scenarios presented above, see “Unaudited Pro Forma Condensed Combined Financial Information.”

Accounting Treatment of the Business Combination

The Business Combination will be accounted for using the acquisition method under the provisions of ASC 805, with Fathom being considered the acquiring entity and Fathom OpCo being considered the acquiree. For

39

accounting purposes, the acquirer is the entity that has obtained control of another entity and thus, consummated a business combination. The determination of whether control has been obtained begins with the evaluation of whether control should be evaluated based on the variable interest or voting interest model pursuant to ASC 810. As defined by U.S. GAAP, if the acquiree is a variable interest entity, the primary beneficiary would always be the accounting acquirer. Fathom OpCo meets the definition of a variable interest entity and Fathom, which will be the managing member, has been determined to be the primary beneficiary. As a result, Fathom is considered to be the accounting acquirer.

Comparison of Corporate Governance and Shareholder Rights

Following the consummation of the Business Combination, the rights of Altimar II shareholders who become Fathom stockholders in the Business Combination will no longer be governed by Altimar II’s Amended and Restated Memorandum and Articles of Association (the “Existing Organizational Documents”) and instead will be governed by the Proposed Charter and the Proposed Bylaws of Fathom. See “The Domestication Proposal — Comparison of Corporate Governance and Shareholders.”

Summary of Risk Factors

You should consider carefully all of the risks described below, together with the other information contained in this proxy statement/prospectus, before voting on the Shareholder Proposals. For purposes of the below summary of risk factors, “we” and “our” refers to Fathom OpCo or Fathom, as the context may require. Such risks include, but are not limited to:

• We are subject to risks related to the ongoing COVID-19 pandemic;

• We may be subject to cybersecurity risks and changes to data protection regulation;

• We face increasing competition in many aspects of our business;

• We may not realize the anticipated benefits of our business acquisitions, and any acquisition, strategic relationship, joint venture or investment could disrupt our business and harm our operating results and financial condition;

• If we are unable to manage our growth and expand our operations successfully, our reputation, brands, business and results of operations may be harmed;

• Our success depends on our ability to deliver on-demand manufacturing capabilities and custom parts that meet the needs of our customers and to effectively respond to changes in our industry;

• Our failure to meet our customers’ expectations regarding quick turnaround time, price or quality could adversely affect our business and results of operations;

• We are subject to risks related to our dependency on our key management members and other key personnel, as well as attracting, retaining and developing qualified personnel in a highly competitive talent market;

• The Proposed Charter will not limit the ability of the CORE Investors and their affiliates to compete with us;

• Through their ownership of our common stock, “negative control” rights and their rights to nominate directors to our board under the Investor Rights Agreement, the CORE Investors will have substantial influence over our management and policies;

• We are subject to risks related to our dependency on Fathom OpCo to pay dividends, taxes, make payments under the Tax Receivable Agreement and pay other expenses;

40

• We may be subject to litigation risks and may face liabilities and damage to our professional reputation as a result;

• Our businesses are subject to extensive domestic and foreign regulations that may subject us to significant costs and compliance requirements;

• We are subject to risks related to effectuating the Domestication including potentially adverse tax consequences and less favorable shareholder rights under the DGCL than under Cayman Islands Law;

• We are subject to risks related to the Tax Receivable Agreement;

• We may be subject to risks related to our status as an emerging growth company within the meaning of the Securities Act;

• In the event that the CORE Investors own more than 50% of Fathom’s outstanding common stock as a result of the Business Combination, we would be subject to the risks related to Fathom being categorized as a “controlled company” within the meaning of the NYSE listing standards;

• Because the Company will become a publicly traded company by means other than a traditional underwritten initial public offering, the Company’s stockholders may face additional risks and uncertainties;

• Altimar II and Fathom OpCo are subject to risks that may prevent the consummation and completion of the Business Combination, including the approval of each Condition Precedent Proposal, the failure to meet closing conditions and the failure of the PIPE Investment to close;

• Some of Altimar II’s officers and directors may have conflicts of interest that may influence or have influenced them to support or approve the Business Combination without regard to your interests or in determining whether Fathom is appropriate for Altimar II’s initial business combination;

• Pre-existing relationships between participants in the Business Combination and the related transactions or their affiliates could give rise to actual or perceived conflicts of interest in connection with the Business Combination;

• If third parties bring claims against Altimar II, the proceeds held in the Trust Account could be reduced and the per share redemption amount received by shareholders may be less than $10.00 per share;

• You may only be able to exercise your Public Warrants on a “cashless basis” under certain circumstances, and if you do so, you will receive fewer Class A common stock from such exercise than if you were to exercise such warrants for cash;

• The grant of registration rights to certain of our investors and the future exercise of such rights may adversely affect the market price of our Class A common stock;

• We may have been a PFIC, which could result in adverse United States federal income tax consequences to U.S. investors;

• We may amend the terms of the warrants in a manner that may be adverse to holders of Public Warrants with the approval by the holders of at least 50% of the then outstanding Public Warrants. As a result, the exercise price of the warrants could be increased, the exercise period could be shortened and the number of Class A ordinary shares purchasable upon exercise of a warrant could be decreased, all without approval of each warrant affected;

• We have identified material weaknesses in our internal control over financial reporting. Failure to achieve and maintain effective internal control over financial reporting could result in our failure to accurately or timely report our financial condition or results of operations which could have a material adverse effect on our business and stock price; and

• The compliance obligations of Altimar II and us under the Sarbanes-Oxley Act require substantial financial and management resources, and increase the time and costs of completing an acquisition.

41

Emerging Growth Company

Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement under the Securities Act declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. We have elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, we, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of Altimar II’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

We will remain an emerging growth company until the earlier of: (1) the last day of the fiscal year (a) following the fifth anniversary of the closing of Altimar II’s IPO, (b) in which we have total annual gross revenue of at least $1.07 billion, or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common equity that is held by non-affiliates exceeds $700 million as of the end of the prior fiscal year’s second fiscal quarter; and (2) the date on which we have issued more than $1.00 billion in non-convertible debt securities during the prior three-year period. References herein to “emerging growth company” have the meaning associated with it in the JOBS Act.

Fathom OpCo management uses Adjusted EBITDA to evaluate Fathom OpCo’s core operating performance and trends, and to make strategic decisions regarding the allocation of capital and new investments. We believe Adjusted EBITDA is useful in evaluating our operating performance, as they are similar to measures reported by our public competitors and are regularly used by security analysts, institutional investors and other interested parties in analyzing operating performance and prospects. Adjusted EBITDA is not intended to be a substitute for any U.S. GAAP financial measure and, as calculated, may not be comparable to other similarly titled measures of performance of other companies in other industries or within the same industry.

SUMMARY UNAUDITED PRO FORMA CONDENSED COMBINED

FINANCIAL INFORMATION OF FATHOM OPCO

The following unaudited pro forma condensed combined financial information presents the combination of the financial information of Altimar Acquisition Corp. II (“Altimar II”) and Fathom Holdco, LLC (“Fathom OpCo”), adjusted to give effect to the Business Combination, the acquisitions of Incodema, Dahlquist, Majestic Metals, Mark Two, Newchem, and GPI completed in 2020 (collectively, the “2020 Acquisitions”) as discussed in further detail in Note 3 – Business Combination in the Fathom Holdco LLC Notes to the Consolidated Financial Statements and the acquisitions of Summit, Centex, Laser, Micropulse West and PPC completed in 2021 (collectively, the “2021 Acquisitions”) as discussed in further detail in Note 20 in the Fathom Holdco LLC Notes to the Consolidated Financial Statements. The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X.

The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2020 combines the historical statements of operations of Altimar II and Fathom OpCo, and gives effect to the 2020 Acquisitions and the 2021 Acquisitions for such period on a pro forma basis as if the Business Combination and the 2020 Acquisitions and 2021 Acquisitions had been consummated and completed on January 1, 2020, the beginning of the period presented. The unaudited condensed combined balance sheet as of September 30, 2021 gives effect to the Business Combination as if it had been completed on September 30, 2021. The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations would have been had the Business Combination, the 2020 Acquisitions and the 2021 Acquisitions taken place on January 1, 2020, nor are they indicative of the future consolidated results of operations or financial position of Fathom Digital Manufacturing Corporation (“Fathom”), the post-combination company.

The unaudited pro forma condensed combined financial statements have been developed from and should be read in conjunction with:

• the accompanying notes to the unaudited pro forma condensed combined financial statements;

• the historical audited financial statements of Altimar II for the period from inception (December 7, 2020) through December 31, 2020 and related notes, found elsewhere in this proxy statement/prospectus;

• the historical audited financial statements of Fathom OpCo for the year ended December 31, 2020, found elsewhere in this proxy statement/prospectus;

• the historical combined audited financial statements of Incodema and Newchem for the year ended December 31, 2019, found elsewhere in this proxy statement/prospectus;

• the historical audited financial statements of Dahlquist for the nine months ended September 30, 2020, found elsewhere in this proxy statement/prospectus;

• the historical audited financial statements of Majestic Metals for the nine months ended September 30, 2020, found elsewhere in this proxy statement/prospectus; and

• other information relating to Altimar II and Fathom OpCo contained in this proxy statement/prospectus, including the Business Combination Agreement and the description of certain terms thereof set forth in the section entitled “The Business Combination.”

Notwithstanding the legal form of the business combination pursuant to the Business Combination Agreement, the Business Combination will be accounted for in accordance with ASC 805, Business Combinations, using the acquisition method. For accounting purposes, the acquirer is the entity that has obtained control of another entity and, thus, consummated a business combination. The determination of whether control has been obtained begins

46

with the evaluation of whether control should be evaluated based on the variable interest or voting interest model pursuant to ASC Topic 810, Consolidation (“ASC 810”). In all redemption scenarios, Fathom has been determined to be the accounting acquirer based on evaluation of the following factors:

• Fathom OpCo is a variable interest entity (“VIE”). Fathom will be the sole managing member and primary beneficiary who has full and complete charge of all affairs of Fathom OpCo, and the Class A units of Fathom OpCo do not have substantive participating or kick out rights; and

• No single party controls Fathom pre and post transaction, hence, the Business Combination is not considered a common control transaction.

The factors discussed above support the conclusion that Fathom will acquire a controlling financial interest in Fathom OpCo and will be the accounting acquirer. Fathom is the primary beneficiary of Fathom OpCo, which is a VIE, since it has the power to direct the activities of Fathom OpCo that most significantly impact Fathom OpCo’s economic performance through its role as the sole managing member of Fathom OpCo, and Fathom’s variable interests in Fathom OpCo include ownership of Fathom OpCo, which results in the right (and obligation) to receive benefits (and absorb losses) of Fathom OpCo that could potentially be significant to Fathom OpCo. Therefore, the Business Combination will be accounted for using the acquisition method. Under this method of accounting, Fathom is treated as the acquirer and Fathom OpCo is treated as the acquired company for financial statement reporting purposes. Upon the consummation of the Business Combination, the assets and liabilities of Fathom OpCo will be recognized at fair value, and any consideration in excess of the fair value of the net assets acquired (including identifiable intangible assets) will be recognized as goodwill.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption into cash of Altimar II’s Public Shares:

• Assuming No Redemptions: This “minimum scenario” presentation assumes that none of the 34,500,000 Public Shares outstanding as of the record date are redeemed by Altimar II’s Public Shareholders.

• Assuming Maximum Redemptions: This presentation assumes that Altimar II’s Public Shareholders redeem 34,500,000 shares of Altimar II’s Class A ordinary shares. This calculation assumes that the full $90 million in aggregate proceeds are received from the PIPE Investment and that the amount in the Trust Account (prior to any redemptions) is equal to $345 million (approximately the amount in the Trust Account as of September 30, 2021), resulting in an aggregate redemption payment (based on an estimated redemption price per share of approximately $10) of $345 million. This scenario results in the following adjustments to the consideration payable at closing:

• Fathom OpCo Owner Consideration: A reduction to the amount of the Closing Cash Consideration of $335 million, such that there will be no Closing Cash Consideration (assuming the Balance Sheet Contribution is $10 million and the Debt Pay-Down Amount is equal to $20 million), and a corresponding increase in the number of shares of Class A common stock and New Fathom Units that comprise the Closing Seller Equity Consideration equal to 33,500,000 (equal to the amount by which Closing Cash Consideration is reduced in this scenario divided by $10), such that the Closing Seller Equity Consideration will be an aggregate number of shares of Class A common stock and Class B common stock equal to 121,293,750.00.

(1) The table below presents our Non-GAAP Pro Forma Adjusted EBITDA reconciled to pro forma net loss, the closest U.S. GAAP measure, for the period indicated.

Pro Forma Adjusted EBITDA is a non-GAAP performance measure presented to supplement our pro forma operating results prepared in accordance with U.S. GAAP, which we believe is useful in evaluating our pro forma operating performance presented above. Pro Forma Adjusted EBITDA, here prepared to give effect to the 2020 Acquisitions and 2021 Acquisitions as if they had been completed on January 1, 2020 is not intended to be a substitute for any U.S. GAAP financial measure and, as calculated, may not be comparable to other similarly titled measure of performance of other companies in other industries or within the same industry. We define and calculate Pro Forma Adjusted EBITDA as pro forma net losses before the impact of interest income or expense, income tax expense and depreciation and amortization, and further adjusted for the following items: stock-based compensation, transaction-related costs, and certain other non-cash and non-core items, as described in the reconciliation below:

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA

PER SHARE FINANCIAL INFORMATION

The following table sets forth historical comparative per share information of Fathom OpCo, on a stand-alone basis, and the unaudited pro forma condensed combined per share information after giving effect to the Business Combination, assuming No Redemptions and Maximum Redemptions, respectively.

The historical information should be read in conjunction with the sections of this proxy statement/prospectus entitled “Fathom OpCo’s Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Altimar II’s Management’s Discussion and Analysis of Financial Condition and Results of Operations,” as well as the historical financial statements and related notes thereto of each of Altimar II and Fathom OpCo included elsewhere in this proxy statement/prospectus. The unaudited pro forma condensed combined per share information is derived from, and should be read in conjunction with, the information contained in the section of this proxy statement/prospectus entitled “Unaudited Pro Forma Condensed Combined Financial Information.”

The unaudited pro forma combined share information does not purport to represent what the actual results of operations of Fathom OpCo would have been had the Business Combination been completed or to project Fathom OpCo’s results of operations that may be achieved after the Business Combination. The unaudited pro forma combined net income per share information below does not purport to represent what the actual results of operations of Fathom OpCo would have been had the Business Combination been completed or to project Fathom OpCo’s results of operations that may be achieved after the Business Combination. The unaudited pro forma shareholders’ equity per share information below does not purport to represent what the value of Altimar II equity and Fathom OpCo equity would have been had the Business Combination been completed nor the shareholders’ equity per share for any future date or period.

The following table sets forth:

• Historical per share information of Altimar II for period from inception (December 7, 2020) through December 31, 2020;

• Historical per share information of Fathom OpCo for the year ended December 31, 2020; and

• Unaudited pro forma per share information of the combined company for the year ended December 31, 2020 after giving effect to the Business Combination, assuming the redemption scenarios as follows:

• Assuming No Redemptions: The “No Redemptions” scenario assumes that no Altimar II Public Shareholders elect to redeem their shares of Altimar II Class A ordinary shares for a pro rata portion of the proceeds on deposit in the Trust Account, and thus the full amount held in the Trust Account as of the date of closing is available for the Business Combination; and

• Assuming Interim Redemptions: This presentation assumes that Public Shareholders holding 17,250,000 shares of Altimar II Class A ordinary shares will exercise redemption rights with respect to their Public Shares for a pro rata share (approximately $10.00 per share) of the funds in the Trust Account.

• Assuming Maximum Redemptions: This presentation assumes that Altimar II’s Public Shareholders redeem 34,500,000 shares of Altimar II’s Class A ordinary shares. This calculation assumes that the full $90 million in aggregate proceeds are received from the PIPE Investment and that the amount in the Trust Account (prior to any redemptions) is equal to $345 million (the amount in the Trust Account as of September 30, 2021), resulting in an aggregate redemption payment (based on an estimated redemption price per share of approximately $10) of $345 million.

RISK FACTORS

In addition to the other information contained in this proxy statement/prospectus, the following risks have the potential to impact the business and operations of Fathom and Fathom OpCo. These risk factors are not necessarily exhaustive. We may face additional risks and uncertainties that are not presently known to us, or that we presently assess to be immaterial, which may also impair our business, financial condition or prospects. All investors are encouraged to perform their own investigation with respect to the business, financial condition and prospects of Fathom and the Business Combination. Unless otherwise indicated or the context otherwise requires, references in this “Risk Factors” section to “Fathom,” the “Company,” “we,” “our,” “us” and other similar terms refer to Fathom and its consolidated subsidiaries, including Fathom OpCo and each of its subsidiaries, after giving effect to the Business Combination.

Risks Related to Our Business Following the Business Combination

Following the Business Combination, the Company will be a holding company with no direct operations that relies on dividends, distributions, loans and other payments, advances and transfers of funds from Fathom OpCo to pay dividends, pay expenses and meet its other obligations. Accordingly, the Company’s securityholders will be subject to all of the risks of Fathom OpCo’s business following the Business Combination. Unless the context otherwise requires, all references in this section to the “Company,” “we,” “us” or “our” refer to Fathom OpCo’s business prior to the completion of the Business Combination, which will be the business of the combined company following the completion of the Business Combination. Accordingly, the risks described below relating to Fathom OpCo could also materially and adversely affect the combined company after the completion of the Business Combination.

Business Risks

We face significant competition and expect to face increasing competition in many aspects of our business, which could cause our operating results to suffer.

The digital manufacturing industry in which we operate is fragmented and highly competitive. We compete for customers with a wide variety of custom parts manufacturers and methods. Some of our current and potential competitors include captive in-house production capabilities, other custom parts manufacturers, brokers of custom parts and additive manufacturing vendors, including those utilizing 3D printing processes. Moreover, some of our existing and potential competitors are researching, designing, developing and marketing other types of products and manufacturing capabilities. We also expect that future competition may arise from the development or improvement of allied or related techniques for digital manufacturing, including from the issuance of patents to other companies that may inhibit our ability to compete effectively. Furthermore, our competitors may attempt to adopt and improve upon key aspects of our business model, such as development of technology that automates much of the manual labor conventionally required to quote and manufacture custom parts, implementation of interactive web-based and automated user interface and quoting systems and/or building scalable operating models specifically designed for efficient custom parts production. Third-party CAD software companies may develop software that mold-makers, injection molders and CNC machine shops could use to compete with our business model. Additive manufacturers may develop stronger, higher temperature resins or introduce other improvements that could more effectively compete with us on part quality. We may also, from time to time, establish alliances or relationships with other competitors or potential competitors, including 3D printer OEMs. To the extent companies terminate such relationships and establish alliances and relationships with our competitors, our business could be harmed.

Existing and potential competitors may have substantially greater financial, technical, marketing and sales, manufacturing, distribution and other resources and name recognition than us, as well as experience and expertise in intellectual property rights, any of which may enable them to compete effectively against us. For example, a number of companies that possess substantial resources have announced that they are beginning digital manufacturing initiatives, which will further strengthen the competition we face.

53

Though we plan to continue to expend resources to develop new technologies, processes and manufacturing capabilities, we cannot assure you that we will be able to maintain our current competitive position or continue to compete successfully against current and future sources of competition. Our challenge in developing new business opportunities is identifying custom parts for which our automated quotation and digital manufacturing processes offer an attractive value proposition, and we may not be able to identify any new custom parts categories with favorable economics similar to our existing offerings. If we do not keep pace with technological change, demand for our offerings may decline and our operating results may suffer.

Our success depends on our ability to deliver on-demand manufacturing capabilities and custom parts that meet the needs of our customers and to effectively respond to changes in our industry.

We derive almost all of our revenue from the manufacture and sale to our customers of quick-turn, low volume custom parts for prototyping, support of internal manufacturing and limited quantity product release up to mid volume production requirements. Our business has been and, we believe, will continue to be, affected by changes in our customers’ new product and product line introductions, requirements and preferences, rapid technological change and the emergence of new standards and practices, any of which could render our technology and manufacturing capabilities less attractive, uneconomical or obsolete. To the extent that our customers’ need for quick-turn to mid-volume production parts decreases significantly for any reason, it would likely have a material adverse effect on our business and operating results and harm our competitive position. In addition, CAD simulation and other technologies may reduce the demand for physical prototype parts. Therefore, we believe that to remain competitive, we must continually expend resources to enhance and improve our technology and manufacturing capabilities.

In particular, we plan to increase our research and development efforts and to continue to focus a significant portion of those efforts to further develop our technology in areas such as our interactive project management platform and manufacturing processes, technology offerings and broaden the range of parts that we are able to manufacture. We believe successful execution of this part of our business plan is critical for our ability to compete in our industry and grow our business, and there are no guarantees we will be able to do so in a timely fashion, or at all. Broadening the range of parts and technologies that we are able to manufacture is of particular importance because limitations in manufacturability are the primary reason we are not able to fulfill many quotation requests. There are no guarantees that the resources we devote to executing on this aspect of our business plan will improve our business and operating results or result in increased demand for our custom parts and manufacturing capabilities. Failures in this area could adversely impact our operating results and harm our reputation and brands. Even if we are successful in executing in this area, our industry is subject to rapid and significant technological change, and our competitors may develop new technologies and manufacturing capabilities that are superior to ours.

Any failure to properly meet the needs of our customers or respond to changes in our industry on a cost-effective and timely basis, or at all, would likely have a material adverse effect on our business and operating results and harm our competitive position.

Our failure to meet our customers’ expectations regarding quick turnaround time, price or quality could adversely affect our business and results of operations.

We believe many of our customers are facing increased pressure from global competitors to be first to market with their finished products, often resulting in a need for quick turnaround of custom parts. We believe our ability to quickly quote, manufacture and ship custom parts has been an important factor in our results to date. There are no guarantees we will be able to meet customers’ increasing expectations regarding quick turnaround time. If we fail to meet our customers’ expectations regarding turnaround time in any given period, our business and results of operations will likely suffer.

Demand for our custom parts and manufacturing capabilities is sensitive to price. We believe our competitive pricing has been an important factor in our results to date. Therefore, changes in our pricing

54

strategies can have a significant impact on our business and ability to generate revenue. Many factors, including our production and personnel costs and our competitors’ pricing and marketing strategies, can significantly impact our pricing strategies. If we fail to meet our customers’ price expectations in any given period, demand for our custom parts and manufacturing capabilities could be negatively impacted and our business and results of operations could suffer.

Most of our customers have a need for specific quality of quick-turn, on-demand custom parts. We believe our ability to create parts meeting our customers’ specifications and quality expectations is an important factor in our results to date. We cannot assure you that we will be able to continue to consistently manufacture custom parts that achieve the production specifications and quality that our customer expect. If we fail to meet our customers’ specifications and quality expectations in any given period, demand for our custom parts and manufacturing capabilities could be negatively impacted and our business and results of operations could suffer.

The strength of our brands is important to our business, and any failure to maintain and enhance our brands would hurt our ability to retain and expand our customer base as well as further penetrate existing customers.

Because our custom parts and manufacturing capabilities are sold primarily through our website, the success of our business depends upon our ability to attract new and repeat customers to our website in order to increase business and grow our revenue. Customer awareness and the perceived value of our brands will depend largely on the success of our marketing efforts, as well as our ability to consistently provide quality custom parts within the required timeframes and positive customer experiences, which we may not do successfully. A primary component of our business strategy is the continued promotion and strengthening of our brands. We may choose to increase our branding expense materially, but we cannot be sure that this investment will be profitable. If we are unable to successfully maintain and enhance our brands, this could have a negative impact on our business and ability to generate revenue.

Sales efforts to large customers involve risks that may not be present or that are present to a lesser extent with respect to sales to smaller organizations.

Attracting and retaining business from large enterprise customers is an element of our business strategy. Sales to large customers involve risks that may not be present or that are present to a lesser extent with sales to smaller organizations, such as longer sales cycles, more complex customer requirements, substantial upfront sales costs, less predictability in completing some of our sales and extended payment terms. A number of factors influence the length and variability of our sales cycle, including the need to educate potential customers about the uses and benefits of our platform, the various technologies available and manufacturing capabilities, the longer period of time for large customers to evaluate and test our project management platform prior to making a purchase decision and placing an order, the discretionary nature of purchasing and budget cycles and the competitive nature of evaluation and purchasing approval processes. As a result, the length of our sales cycle, from identification of the opportunity to deal closure, may vary significantly from customer to customer, with sales to large enterprises typically taking longer to complete. Moreover, larger organizations may demand more customization, which would increase our upfront investment in the sales effort with no guarantee that these customers will seek to use our manufacturing capabilities widely enough across their organization to justify our substantial upfront investment. A portion of these customers may purchase our offerings on payment terms, requiring us to assume a credit risk for non-payment in the ordinary course of business. If we fail to effectively manage these risks associated with sales to large customers, our business, financial condition and results of operations may be affected.

Our business depends in part on our ability to process a large volume of new custom part designs from a diverse group of customers and successfully identify significant opportunities for our business based on those submissions.

We believe the volume of new custom part designs we process and the size and diversity of our customer base give us valuable insight into the needs of our prospective customers. We utilize this industry knowledge to

55

determine where we should focus our development resources. If the number of new custom part designs we process or the size and diversity of our customer base decrease, our ability to successfully identify significant opportunities for our business and meet the needs of customers could be negatively impacted. In addition, even if we do continue to process a large number of new custom part designs and work with a significant and diverse customer base, there are no guarantees that any industry knowledge we extract from those interactions will be successfully utilized to help us identify significant business opportunities or better understand the needs of our existing or prospective customers.

Wage increases and pressure in certain geographies may prevent us from sustaining our competitive advantage and may reduce our profit margin.

Measures are being taken in the United States and globally to increase minimum wages, and there is a shortage of skilled labor in certain locations leading to increased wage pressure. Similarly, with an increased global focus on environmental, social and corporate-governance concerns and sustainability, input costs have been steadily rising. In addition, enhanced federally subsidized unemployment benefits during the ongoing COVID-19 pandemic may have been contributing to labor shortages at some of our facilities. Accordingly, we may need to increase the levels of labor compensation more rapidly than in the past to remain competitive in attracting and retaining the quality and amount of labor that our business requires. To the extent that we are not able to control or share wage increases, wage increases may reduce our margins and cash flows, which could adversely affect our business.

The loss of one or more key members of our management team or personnel, or our failure to attract, integrate and retain additional personnel in the future, could harm our business and negatively affect our ability to successfully grow our business.

We are highly dependent upon the continued service and performance of the key members of our management team and other personnel. The loss of any of these individuals, each of whom is “at will” and may terminate his or her employment relationship with us at any time, could disrupt our operations and significantly delay or prevent the achievement of our business objectives. We believe that our future success will also depend in part on our continued ability to identify, hire, train and motivate qualified personnel. High demand exists for senior management and other key personnel (including technical, engineering, product, finance and sales personnel) in the digital manufacturing industry. A possible shortage of qualified individuals in the regions where we operate might require us to pay increased compensation to attract and retain key employees, thereby increasing our costs. In addition, we face intense competition for qualified individuals from numerous companies, many of whom have substantially greater financial and other resources and name recognition than us. We may be unable to attract and retain suitably qualified individuals who are capable of meeting our growing operational, managerial and other requirements, or we may be required to pay increased compensation in order to do so. For example, our failure to attract and retain shop floor employees may inhibit our ability to fulfill production orders for our customers. Our failure to attract, hire, integrate and retain qualified personnel could impair our ability to achieve our business objectives.

All of our employees are at-will employees, meaning that they may terminate their employment relationship with us at any time, and their knowledge of our business and industry would be extremely difficult to replace. We generally enter into non-competition agreements with our employees and certain consultants. These agreements prohibit our employees and applicable consultants from competing directly with us or working for our competitors or customers while they work for us, and in some cases, for a limited period after they cease working for us. We may be unable to enforce these agreements under the laws of the jurisdictions in which our employees and applicable consultants work and it may be difficult for us to restrict our competitors from benefiting from the expertise that our former employees or consultants developed while working for us. If we cannot demonstrate that our legally protectable interests will be harmed, we may be unable to prevent our competitors from benefiting from the expertise of our former employees or consultants and our ability to remain competitive may be diminished.

Our growth strategy relies on business acquisitions. We may not realize the anticipated benefits of such acquisitions, and any acquisition, strategic relationship, joint venture or investment could disrupt our business and harm our operating results and financial condition.

Our business and customer base have been built in part through organic growth, but also through acquisitions of businesses that increase market share in our current markets or expand into other markets, or broaden our technology, intellectual property or product line capabilities. We have completed 13 acquisitions during the last three years, and we intend to continue to aggressively pursue attractive opportunities to enhance or expand our offerings through acquisitions, strategic relationships, joint ventures or investments that we believe may allow us to implement our growth strategy. For example, in December 2019, we acquired ICOMold to enable us to expand our existing SEO and SEM capabilities; during 2020 and 2021 to date, we completed six acquisitions that added CNC machining to our manufacturing capabilities, and three acquisitions that added precision sheet metal fabrication to our offerings. We cannot forecast the number, timing or size of any future acquisitions or other similar strategic transactions, or the effect that any such transactions might have on our operating or financial results. We may not be able to successfully identify future acquisition opportunities or complete any such acquisitions if we cannot reach agreement on commercially favorable terms, if we lack sufficient resources to finance the transaction on our own and cannot obtain financing at a reasonable cost or if regulatory authorities prevent such transactions from being completed.

Although we have substantial experience engaging in these types of transactions, such transactions may be complex, time consuming and expensive, and may present numerous challenges and risks including:

• an acquired company, asset or technology not furthering our business strategy as anticipated;

• difficulties entering and competing in new product or geographic markets and increased competition, including price competition;

• integration challenges;

• challenges in working with strategic partners and resolving any related disagreements or disputes;

• high valuation for a company, asset or technology, or changes in the economic or market conditions or assumptions underlying our decision to make an acquisition;

• significant problems or liabilities associated with acquired businesses, assets or technologies, including increased intellectual property and employment-related litigation exposure;

• acquisition of a significant amount of goodwill, which could result in future impairment charges that would reduce our earnings; and

• requirements to record substantial charges and amortization expense related to certain purchased intangible assets, deferred stock compensation and other items, as well as other charges or expenses.

Any one of these challenges or risks could impair our ability to realize any benefit from our acquisitions, strategic relationships, joint ventures or investments after we have expended resources on them, as well as divert our management’s attention. Any failure to successfully address these challenges or risks could disrupt our business and harm our operating results and financial condition. Moreover, any such transaction may not be viewed favorably by investors or other stakeholders.

If we proceed with a particular acquisition, we may have to use cash, issue new equity securities with dilutive effects on existing stockholders, incur indebtedness, assume contingent liabilities, or amortize assets or expenses in a manner that might have a material adverse effect on our financial condition and results of operations. Acquisitions will also require us to record certain acquisition-related costs and other items as current period expenses, which would have the effect of reducing our reported earnings in the period in which an acquisition is consummated. In addition, we could also face unknown liabilities or write-offs due to our acquisitions, which could result in a significant charge to our earnings in the period in which they occur. We will also be required to record any goodwill or other long-lived asset impairment charges in the periods in which they occur, which could result in a significant charge to our earnings in any such period.

57

Achieving the expected returns and synergies from future acquisitions will depend, in part, upon our ability to integrate the products and services, technology, administrative functions and personnel of these businesses into our offering lines in an efficient and effective manner. We cannot assure you that we will be able to do so, that any acquired businesses will perform at levels and on the timelines anticipated by our management or that we will be able to obtain these synergies. In addition, acquired technologies and intellectual property may be rendered obsolete or uneconomical by our own or our competitors’ technological advances. Management resources may also be diverted from operating our existing businesses to certain acquisition integration challenges. If we are unable to successfully integrate acquired businesses, our anticipated revenues and profits may be lower. Our profit margins may also be lower, or diluted, following the acquisition of companies whose profit margins are less than those of our existing businesses.

In addition, from time to time we may enter into negotiations for acquisitions, relationships, joint ventures or investments that are not ultimately consummated. These negotiations could result in significant diversion of management time, as well as substantial out-of-pocket costs.

If we are unable to manage our growth and expand our operations successfully, our reputation and brands may be damaged, and our business and results of operations may be harmed.

Over the past several years, we have experienced rapid growth. For example, we have grown from 44 full-time employees as of October 31, 2018 to 668 full-time employees as of September 30, 2021. We expect this growth to continue and the number of facilities from which we operate to increase in the future. Our ability to effectively manage our anticipated growth and expansion of our operations will require us to do, among other things, the following:

• enhance our operational, financial and management controls and infrastructure, human resource policies, and reporting systems and procedures;

• effectively scale our operations, including accurately predicting the need for floor space, equipment, and additional staffing; and

• successfully identify, recruit, hire, train, develop, maintain, motivate and integrate additional employees.

These enhancements and improvements will require significant capital expenditures and allocation of valuable management and employee resources. Furthermore, our growth has placed, and will continue to place, a strain on our operational, financial and management infrastructure. Our future financial performance and our ability to execute on our business plan will depend, in part, on our ability to effectively manage any future growth and expansion. There are no guarantees we will be able to do so in an efficient or timely manner, or at all. Our failure to effectively manage growth and expansion could have a material adverse effect on our business, results of operations, financial condition, prospects, reputation and brands, including impairing our ability to perform to our customers’ expectations.

We may not timely and effectively scale and adapt our existing technology, processes and infrastructure to meet the needs of our business.

A key element to our continued growth is the ability to quickly and efficiently quote an increasing number of customer submissions across geographic regions and to manufacture the related custom parts. This will require us to timely and effectively scale and adapt our existing technology, processes and infrastructure to meet the needs of our business. With respect to our website, project management platform and quoting technology, it may become increasingly difficult to maintain and improve their performance, especially during periods of heavy usage and as our solutions become more complex and our user traffic increases across geographic regions. Similarly, our manufacturing automation technology may not enable us to process the large numbers of unique designs and efficiently manufacture the related custom parts in a timely fashion to meet the needs of our

58

customers as our business continues to grow. Any failure in our ability to timely and effectively scale and adapt our existing technology, processes and infrastructure could negatively impact our ability to retain existing customers and attract new customers, damage our reputation and brands, result in lost revenue, and otherwise substantially harm our business and results of operations.

We may require additional capital to support business growth, and this capital might not be available on acceptable terms, if at all. If we are unable to raise additional capital when needed, our financial condition could be adversely affected and we may not be able to execute our growth strategy.

We intend to continue to make acquisitions and other investments to support our business growth and may require additional funds to respond to business challenges, including the need to complement our growth strategy, increase market share in our current markets or expand into other markets, or broaden our technology, intellectual property or manufacturing capabilities. Accordingly, we may need to obtain equity or debt financings to secure additional funds. If we raise additional funds through future issuances of equity or convertible debt securities, our existing stockholders could suffer significant dilution, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. We may not be able to obtain additional financing on terms favorable to us, if at all. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to support our business growth and to respond to business challenges could be significantly impaired, and our business may be adversely affected.

Numerous factors may cause us not to maintain the revenue growth that we have historically experienced.

Although our revenue has grown from $20.6 million for the year ended December 31, 2019 to $61.3 million for the year ended December 31, 2020, we may not be able to maintain our historical rate of revenue growth. We believe that our continued revenue growth will depend on many factors, a number of which are out of our control, including among others, our ability to:

• retain and further penetrate existing customers, as well as attract new customers;

• consistently execute on custom part orders in a manner that satisfies our customers’ product needs and provides them with a superior experience;

• develop new technologies or manufacturing processes and broaden the range of custom parts we offer;

• capitalize on customers’ product expectations for access to comprehensive, user-friendly e-commerce capabilities 24 hours per day, 7 days per week;

• increase the strength and awareness of our brands across geographic regions;

• respond to changes in customers’ needs, technology and our industry;

• react to challenges from existing and new competitors; and

• respond to an economic recession which negatively impacts manufacturers’ ability to innovate and bring new products to market.

• We cannot assure you that we will be successful in addressing the factors above and continuing to grow our business and revenue.

Errors or defects in the software we use or custom parts we manufacture could cause us to incur additional costs, lose revenue and business opportunities, damage our reputation and expose us to potential liability.

The sophisticated software we use and the often complex custom parts we manufacture may contain errors, defects or other performance problems at any point in the life of the software or custom parts. If errors or defects

59

are discovered in our current or future software or in the custom parts we manufacture for customers, we may not be able to correct them in a timely manner or provide an adequate response to our customers. We may therefore need to expend significant financial, technical and management resources, or divert some of our development resources, in order to resolve or work around those defects. We may also experience an increase in our service and warranty costs. Particularly in the medical sector, errors or defects in our software or custom parts we manufacture could lead to claims by patients against us and our customers and expose us to lawsuits that may damage our and our customers’ reputations. Claims may be made by individuals or by classes of users. Our product liability and related insurance policies may not apply or sufficiently cover any product liability lawsuit that arises from defective software we may use or the custom parts we manufacture. Customers such as our collaboration partners may also seek indemnification for third party claims allegedly arising from breaches of warranties under our collaboration agreements.

Errors, defects or other performance problems in the software we use or custom parts we manufacture may also result in the loss of, or delay in, the market acceptance of our platform and digital manufacturing capabilities. Such difficulties could also cause us to lose customers and, particularly in the case of our largest customers, the potentially substantial associated revenue which would have been generated by our sales to companies participating in our customer’s supply chain. Technical problems, or the loss of a customer with a particularly important national or global reputation, could also damage our own business reputation and cause us to lose new business opportunities.

Interruptions to or other problems with our website, project management platform, information technology systems, manufacturing processes or other operations could damage our reputation and brands and substantially harm our business and results of operations.

The satisfactory performance, reliability, consistency, security and availability of our website and interactive project management platform, information technology systems, manufacturing processes and other operations are critical to our reputation and brands, and to our ability to effectively service customers. Any interruptions or other problems that cause any of our website, interactive project management platform or information technology systems to malfunction or be unavailable, or negatively impact our manufacturing processes or other operations, may damage our reputation and brands, result in lost revenue, cause us to incur significant costs seeking to remedy the problem and otherwise substantially harm our business and results of operations.

A number of factors or events could cause such interruptions or problems, including among others: human and software errors, design faults, challenges associated with upgrades, changes or new facets of our business, power loss, telecommunication failures, fire, flood, extreme weather, political instability, acts of terrorism, war, break-ins and security breaches, contract disputes, labor strikes and other workforce-related issues, capacity constraints due to an unusually large number of customers and potential customers accessing our website or project management platform or ordering parts at the same time, and other similar events. These risks are augmented by the fact that our customers come to us largely for our quick-turn low to mid-volume manufacturing capabilities and that accessibility and turnaround speed are often of critical importance to these customers. We are dependent upon our facilities through which we satisfy all of our production demands and in which we house all of the computer hardware necessary to operate our website and systems as well as managerial, customer service, sales, marketing and other similar functions, and we have not identified alternatives to these facilities or established fully redundant systems in multiple locations. In addition, we are dependent in part on third parties for the implementation and maintenance of certain aspects of our communications and production systems, and therefore preventing, identifying and rectifying problems with these aspects of our systems is to a large extent outside of our control.

Moreover, the business interruption insurance that we carry may not be sufficient to compensate us for the potentially significant losses, including the potential harm to the future growth of our business that may result from interruptions in our offerings and manufacturing processes as a result of system failures.

60

If a natural or man-made disaster strikes any of our manufacturing facilities, we may be unable to manufacture our products for a substantial period of time and our sales will decline.

We manufacture all of our products in 12 manufacturing facilities located in the United States. These facilities and the manufacturing equipment we use would be costly to replace if damaged by a natural or man-made disaster, and could require substantial lead time to repair or replace. Our facilities may be harmed by natural or man-made disasters, including, without limitation, earthquakes, floods, tornadoes, fires, hurricanes, tsunamis, nuclear disasters, terrorist attacks, or as a result of the ongoing COVID-19 pandemic. In the event any of our facilities are affected by a disaster, we may:

• be unable to meet the shipping deadlines of our customers;

• experience disruptions in our ability to process submissions and generate quotations, manufacture and ship parts, provide marketing and sales support and customer service and otherwise operate our business, any of which could negatively impact our business;

• be forced to rely on third-party manufacturers;

• need to expend significant capital and other resources to address any damage caused by the disaster; and

• lose customers and be unable to reacquire those customers.

Although we possess insurance for damage to our property and the disruption of our business from casualties, this insurance may not be sufficient to cover all of our potential losses and may not continue to be available to us on acceptable terms, or at all.

If our present single or limited source suppliers become unavailable or inadequate, our customer relationships, results of operations and financial condition may be adversely affected.

We acquire substantially all of the manufacturing equipment and certain of our materials that are critical to the ongoing operation and future growth of our business from third parties. We do not have long-term supply contracts with any of our suppliers and operate on a purchase-order basis. While most manufacturing equipment and materials for our products are available from multiple suppliers, certain of those items are only available from single or limited sources. Should any of our present single or limited source suppliers for manufacturing equipment or materials become unavailable or inadequate, or impose terms unacceptable to us such as increased pricing terms, we could be required to spend a significant amount of time and expense to develop alternate sources of supply, and we may not be successful in doing so on terms acceptable to us, or at all. Natural disasters, such as hurricanes or tornadoes, may affect our supply of materials, particularly resins, from time to time, and we may purchase larger amounts of certain materials in anticipation of future shortages or increases in pricing. In addition, if we were unable to find a suitable supplier for a particular type of manufacturing equipment or material, we could be required to modify our existing manufacturing processes and offerings to accommodate the situation. As a result, the loss of a single or limited source supplier could adversely affect our relationship with our customers and our results of operations and financial condition.

We are subject to payment-related risks.

We accept payments using a variety of methods, including credit card, customer invoicing, physical bank check and payment upon delivery. As we offer new payment options to our customers, we may be subject to additional regulations, compliance requirements and fraud risk. For certain payment methods, including credit and debit cards, we pay interchange and other fees, which may increase over time and raise our operating costs and lower profitability. We rely on third parties to provide payment processing services, including the processing of credit cards, debit cards or electronic checks, and it could disrupt our business if these companies become unwilling or unable to provide these services to us. We are also subject to payment card association operating rules, certification requirements and rules governing electronic funds transfers, which could change or be

61

reinterpreted to make it difficult or impossible for us to comply. If we fail to comply with these rules or requirements, we may be subject to fines and higher transaction fees and lose our ability to accept credit and debit card payments from our customers, process electronic funds transfers, or facilitate other types of online payments, and our business and operating results could be adversely affected.

Workplace accidents or environmental damage could result in substantial remedial obligations and damage to our reputation.

Accidents or other incidents that occur at our manufacturing and other facilities or involve our personnel or operations could result in claims for damages against us. In addition, in the event we are found to be financially responsible, as a result of environmental or other laws or by court order, for environmental damages alleged to have been caused by us or occurring on our premises, we could be required to pay substantial monetary damages or undertake expensive remedial obligations. The amount of any costs, including fines or damages payments that we might incur under such circumstances, could substantially exceed any insurance we have to cover such losses. Any of these events, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations and could adversely affect our reputation.

Interruptions, delays in service or inability to increase capacity at third-party data center facilities could adversely affect our business and reputation.

Our business, brands, reputation and ability to attract and retain customers depend upon the satisfactory performance, reliability and availability of our project management platform, depend upon the availability of the internet and our third-party service providers. We rely on third party data center facilities operated by Amazon Web Services (“AWS”), Ace Cloud Hosting (“Ace”), and Right Networks (“Right Networks”) to host our main servers. We do not control the operation of any of AWS’, Ace’s or Right Networks’ data center hosting facilities, and they may be subject to damage or interruption from earthquakes, floods, fires, power loss, telecommunications failures, terrorist attacks and similar events. They may also be subject to interruptions due to system failures, computer viruses, software errors or subject to breaches of computer hardware and software security, break-ins, sabotage, intentional acts of vandalism and similar misconduct. And while we rely on service level agreements with our hosting providers, if they do not properly maintain their infrastructure or if they incur unplanned outages, our customers may experience performance issues or unexpected interruptions and we may not meet our service level agreement terms with our customers. We have experienced, and expect that in the future we may experience interruptions, delays and outages in service and availability from time to time due to a variety of factors, including infrastructure changes, human or software errors, website hosting disruptions and capacity constraints. These and other similar events beyond our control could negatively affect the use, functionality or availability of our services.

Any damage to, or failure of, our systems, or those of our third-party providers, could interrupt or hinder the use or functionality of our website or project management platform. Resulting impairment of or interruptions of our business may reduce revenue, subject us to claims and litigation, cause customers to terminate their contracts and adversely affect our ability to attract new customers. If we are forced to switch hosting facilities, we may not be successful in finding an alternative service provider on acceptable terms or in hosting the computer servers ourselves. Our business will also be harmed if customers and potential customers believe our systems are unreliable.

The audit report we received with respect to our audited financial statements for the years ended December 31, 2020 and December 31, 2019 included emphasis of a matter regarding going concern. We must raise additional capital before April 29, 2022 to refinance our debt, and funding of the credit facilities provided for under our New Credit Agreement for this purpose is conditioned upon the completion of the Business Combination.

As of the date of this proxy statement/prospectus, the principal amount outstanding under Fathom OpCo’s 2021 Term Loan was $170 million. The 2021 Term Loan matures for repayment on April 29, 2022. If Fathom

62

OpCo is unable to complete a significant capital transaction such as the Business Combination prior to April 9, 2022, and obtain funding of the credit facilities provided for under the New Credit Agreement, Fathom OpCo expects that it would not have sufficient funds on hand and from cash flow from operations to repay the 2021 Term Loan when it matures on April 29, 2022, which could result in our inability to continue as a going concern. The Business Combination is subject to customary closing conditions, some of which are out of Fathom OpCo’s control and, as a consequence, there can be no guarantee that the Business Combination and the funding of the credit facilities provided for under the New Credit Agreement will be completed. Accordingly, Grant Thornton LLP, Fathom OpCo’s independent registered public accounting firm, without modifying its opinion included a going concern emphasis paragraph in its audit report covering the audited financial statements of Fathom OpCo included in this proxy statement/prospectus. See the section entitled “Fathom Indebtedness” for a description of the 2021 Term Loan and the New Credit Agreement.

Industry Risks

The COVID-19 pandemic has adversely affected our business and results of operations. The duration and extent to which it will continue to adversely impact our business and results of operations remains uncertain and could be material.

The COVID-19 pandemic has resulted in a widespread public health crisis and numerous significant disease control measures being taken to limit its spread, including travel bans and restrictions, quarantines, shelter-in-place orders and shutdowns. These measures have materially impacted and may impact our workforce and operations, the operations of our customers, and those of our respective vendors and suppliers. Our operations are located in the United States, and domestic and global measures taken in effort to contain the pandemic has caused disruptions at some of our manufacturing operations and facilities as well as supplier facilities. Further such disruptions could occur in the future and any such disruptions could materially adversely affect our business. The impact of the pandemic on our business has included and could in the future include:

• disruptions to or restrictions on our ability to ensure the continuous provision of our manufacturing services and solutions;

• reductions in our capacity utilization levels;

• temporary closures of our direct and indirect suppliers, resulting in adverse effects to our supply chain, and other supply chain disruptions, which adversely affect our ability to procure sufficient inventory to support customer orders;

• temporary shortages of skilled employees available to staff manufacturing facilities due to shelter-in-place orders and travel restrictions within as well as into and out of countries;

• restrictions or disruptions of transportation, such as reduced availability of air transport, port closures and increased border controls or closures;

• increases in operational expenses and other costs related to requirements implemented to mitigate the impact of the pandemic;

• delays or limitations on the ability of our customers to perform or make timely payments;

• reductions in short- and long-term demand for our manufacturing services and solutions, or other disruptions in technology buying patterns;

• workforce disruptions due to illness, quarantines, governmental actions, other restrictions and/or the social distancing measures we have taken to mitigate the impact of COVID-19 at our locations in an effort to protect the health and well-being of our employees, customers, suppliers and of the communities in which we operate (including certain employees working from home, restricting the number of employees attending events or meetings in person, limiting the number of people in our buildings and factories at any one time, further restricting access to our facilities and suspending employee travel); and

63

• our management team continuing to commit significant time, attention and resources to monitoring the COVID-19 pandemic and seeking to mitigate its effects on our business and workforce.

The global spread of COVID-19 also has created significant macroeconomic uncertainty, volatility and disruption, which may adversely affect our and our customers’ and suppliers’ liquidity, cost of capital and ability to access the capital markets. Even after the COVID-19 pandemic has subsided, we may continue to experience adverse impacts to our business as a result of the pandemic’s global economic impact, including any recession, economic downturn, government spending cuts, tightening of credit markets or increased unemployment that has occurred or may occur in the future, which could cause our customers and potential customers to postpone or reduce spending on our manufacturing services and solutions.

Global economic conditions may harm our ability to do business, increase our costs and negatively affect our stock price.

Our performance depends on the financial health and strength of our customers, which in turn is dependent on the economic conditions of the markets in which we and our customers operate. Declines in the global economy, difficulties in the financial services sector and credit markets, continuing geopolitical uncertainties, and other macroeconomic factors all affect the spending behavior of existing and potential customers.

We also face risks from financial difficulties or other uncertainties experienced by our suppliers, distributors or other third parties on which we rely. If third parties are unable to supply us with required materials or services or otherwise assist us in operating our business, our business could be harmed.

For example, the possibility of an ongoing trade war between the United States and China may impact the cost of raw materials, finished products or other materials used in our offerings and our ability to sell our offerings in China. Other changes in U.S. social, political, regulatory, and economic conditions or in laws and policies governing foreign trade, manufacturing, development and investment could also adversely affect our business. We could experience interruptions in production due to the processing of customs formalities or reduced customer spending in the wake of weaker economic performance. If global economic conditions remain volatile for a prolonged period our results of operations could be adversely affected.

If demand for our offerings and manufacturing capabilities does not grow as expected, or if market adoption of digital manufacturing does not continue to develop, or develops more slowly than expected, our revenues may stagnate or decline and our business may be adversely affected.

The industrial manufacturing market, which today is dominated by conventional manufacturing processes that do not involve digital manufacturing technology, is undergoing a shift towards digital manufacturing. We may not be able to develop effective strategies to raise awareness among potential customers of the benefits of digital manufacturing technologies or our offerings and manufacturing capabilities may not address the specific needs or provide the level of functionality required by potential customers to encourage the continuation of this shift towards digital manufacturing. If digital manufacturing technology does not continue to gain broader market acceptance as an alternative to conventional manufacturing processes, or if the marketplace adopts digital manufacturing technologies and capacities developed by our competitors, we may not be able to increase or sustain the level of sales of our offerings and our operating results would be adversely affected as a result.

We could face liability if our digital manufacturing solutions are used by our customers to print dangerous objects.

Customers may use our digital manufacturing offerings to produce parts that could be used in a harmful way or could otherwise be dangerous. For example, there have been news reports that 3D printers were used to print guns or other weapons. We have little, if any, control or knowledge over the parts we manufacture for our customers using our offerings, and it may be difficult, if not impossible, for us to monitor and prevent customers

64

from having certain components of weapons or other dangerous objects manufactured with our services. While we have never digitally manufactured weapons for customers, there can be no assurance that we will not be held liable if someone were injured or killed by a weapon or other dangerous object containing a component part or parts manufactured for a customer using one of our offerings.

Because the digital manufacturing market is rapidly evolving, forecasts of market growth in this proxy statement/prospectus may not be accurate.

Market opportunity estimates and growth forecasts included in this proxy statement/prospectus are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The forecasts and estimates in this proxy statement/prospectus relating to the expected size and growth of the markets for digital manufacturing technology and other markets in which we participate may prove to be inaccurate. Even if these markets experience the forecasted growth described in this proxy statement/prospectus, we may not grow our business at similar rates, or at all. Our future growth is subject to many factors, including continued market adoption of our offerings, which is subject to many risks and uncertainties. Accordingly, the forecasts and estimates of market size and growth described in this proxy statement/prospectus should not be taken as indicative of our future growth. In addition, these forecasts do not consider the impact of the ongoing global COVID-19 pandemic, and we cannot assure you that these forecasts will not be materially and adversely affected as a result.

Our actual results may be significantly different from our projections, estimates, targets or forecasts.

The projections, estimates, targets and forecasts contained in this proxy statement/prospectus are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond our control. While all projections, estimates, targets and forecasts are necessarily speculative, we believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out in time the projection, estimate, target or forecast extends from the date of preparation. The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those contained in such projections, estimates, targets and forecasts. Our projections, estimates, targets and forecasts should not be regarded as an indication that Fathom OpCo or its representatives considered or consider such financial projections, estimates, targets and forecasts to be a reliable prediction of future events.

Intellectual Property and Infrastructure-Related Risks

We may not be able to adequately protect or enforce our intellectual property rights, which could impair our competitive position.

Our success and future revenue growth will depend, in part, on our ability to protect our intellectual property. We rely primarily on patents, licenses, trademarks and trade secrets, as well as non-disclosure agreements and other methods, to protect our proprietary technologies and processes globally. Despite our efforts to protect our proprietary technologies and processes, it is possible that competitors or other unauthorized third parties may obtain, copy, use or disclose our technologies and processes or invent around our patents. We cannot assure you that any of our existing or future patents will not be challenged or invalidated in court or patent office proceedings that could be time-consuming, expensive and distract us from operating our business. In addition, competitors could circumvent our patents by inventing around them. As such, any rights granted under these patents may not provide us with meaningful protection. We may not be able to obtain foreign patents corresponding to our United States patents. Even if foreign patents are granted, effective enforcement in foreign countries may not be available. If our patents and other intellectual property do not adequately protect our proprietary technology, our competitors may be able to offer product lines similar to ours. Our competitors may also be able to develop similar technology independently or design around our patents. Any of the foregoing events would lead to increased competition and lower revenue or gross margin, which would adversely affect our net income.

65

We may incur substantial costs enforcing or acquiring intellectual property rights and defending against third-party claims as a result of litigation or other proceedings. Our failure to expand our intellectual property portfolio could adversely affect the growth of our business and results of operations.

We may incur substantial expense and costs in protecting, enforcing and defending our intellectual property rights against third parties. Intellectual property disputes may be costly and can be disruptive to our business operations by diverting attention and energies of management and key technical personnel and by increasing our costs of doing business. Third-party intellectual property claims asserted against us could subject us to significant liabilities, require us to enter into royalty and licensing arrangements on unfavorable terms, prevent us from providing our offerings to customers, subject us to injunctions prohibiting or restricting our sale of our offerings, or require us to redesign our offerings, causing severe disruptions to our operations or the marketplaces in which we compete or require us to satisfy indemnification commitments with our customers, including contractual provisions under various license arrangements. In addition, we may incur significant costs in acquiring the necessary third-party intellectual property rights for use in our offerings. Any of these could have an adverse effect on our business and financial condition.

Patent applications in the United States and most other countries are confidential for a period of time until they are published, and the publication of discoveries in scientific or patent literature typically lags actual discoveries by several months or more. As a result, the nature of claims contained in unpublished patent filings around the world is unknown to us, and we cannot be certain that we were the first to conceive inventions covered by our patents or patent applications or that we were the first to file patent applications covering such inventions. Furthermore, it is not possible to know in which countries patent holders may choose to extend their filings under the Patent Cooperation Treaty or other mechanisms.

In addition, we may be subject to intellectual property infringement claims from individuals, vendors and other companies, including those that are in the business of asserting patents, but are not commercializing products or services in the field of digital manufacturing, or our customers may seek to invoke indemnification obligations to involve us in such intellectual property infringement claims. Furthermore, although we maintain certain procedures to screen custom parts we manufacture on behalf of customers for infringement on the intellectual property rights of others, we cannot be certain that our procedures will be effective in preventing any such infringement. Any third-party lawsuits or other assertion to which we are subject, alleging infringement of trademarks, patents, trade secrets or other intellectual property rights either by us or by our customers may have a significant adverse effect on our financial condition.

Cybersecurity risks and cyber incidents, including cyber-attacks, could adversely affect our business by causing a disruption to our operations, a compromise or corruption of our confidential information and confidential information in our possession and damage to our business relationships, any of which could negatively impact our business, financial condition and operating results.

There has been an increase in the frequency and sophistication of the cyber and security threats we face, with attacks ranging from those common to businesses generally to those that are more advanced and persistent, which may target us due to our substantial reliance on information technology or otherwise. Cyber-attacks and other security threats could originate from a wide variety of sources, including cyber criminals, nation state hackers, hacktivists and other outside parties. As a result of the generally increasing frequency and sophistication of cyber-attacks, and our substantial reliance on technology, we may face a heightened risk of a security breach or disruption with respect to sensitive information resulting from an attack by computer hackers, foreign governments or cyber terrorists.

The operation of our business is dependent on computer hardware and software systems, as well as data processing systems and the secure processing, storage and transmission of information, which are vulnerable to security breaches and cyber incidents. A cyber incident is considered to be any adverse event that threatens the confidentiality, integrity or availability of our information resources. These incidents may be an intentional attack or

66

an unintentional event and could involve gaining unauthorized access to our information systems for purposes of misappropriating assets, stealing confidential information, corrupting data or causing operational disruption. In addition, we and our employees may be the target of fraudulent emails or other targeted attempts to gain unauthorized access to proprietary or other sensitive information. The result of these incidents may include disrupted operations, misstated or unreliable financial data, fraudulent transfers or requests for transfers of money, liability for stolen information, increased cybersecurity protection and insurance costs, litigation and damage to our business relationships, causing our business and results of operations to suffer. Our reliance on information technology is substantial, and accordingly the risks posed to our information systems, both internal and those provided by third-party service providers are critical. We have implemented processes, procedures and internal controls designed to mitigate cybersecurity risks and cyber intrusions and rely on industry accepted security measures and technology to securely maintain confidential and proprietary information maintained on our information systems; however, these measures, as well as our increased awareness of the nature and extent of a risk of a cyber-incident, do not guarantee that a cyber-incident will not occur and/or that our financial results, operations or confidential information will not be negatively impacted by such an incident, especially because the cyber-incident techniques change frequently or are not recognized until launched and because cyber-incidents can originate from a wide variety of sources.

Those risks are exacerbated by the rapidly increasing volume of highly sensitive data, including our and our customers’ proprietary business information and intellectual property, and personally identifiable information of our employees and customers, that we collect and store in our data centers and on our networks. The secure processing, maintenance and transmission of this information are critical to our operations. A significant actual or potential theft, loss, corruption, exposure, fraudulent use or misuse of employee, customer or other personally identifiable or our or our customers’ proprietary business data, whether by third parties or as a result of employee malfeasance (or the negligence or malfeasance of third party service providers that have access to such confidential information) or otherwise, non-compliance with our contractual or other legal obligations regarding such data or intellectual property or a violation of our privacy and security policies with respect to such data could result in significant remediation and other costs, fines, litigation or regulatory actions against us and significant reputational harm.

Our proprietary digital manufacturing software contains third-party open-source software components. Our use of such open-source software may expose us to additional risks and harm our intellectual property and failure to comply with the terms of the underlying open-source software licenses could restrict our ability to sell our offerings.

Our proprietary digital manufacturing software contains components that are licensed under so-called “open source,” “free” or other similar licenses. Open source software is made available to the general public on an “as-is” basis under the terms of a non-negotiable license. We currently combine our proprietary software with open source software, but not in a manner that we believe requires the release of the source code of our proprietary software to the public. We do not plan to integrate our proprietary software with open source software in ways that would require the release of the source code of our proprietary software to the public; however, our use of open source software may entail greater risks than use of third-party commercial software. Open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. In addition, if we combine our proprietary software with open source software in a certain manner, we could, under certain open source licenses, be required to release to the public or remove the source code of our proprietary software. As is standard practice among technology companies, Fathom OpCo leverages open source software in the development of its internal software. Open source software is commonly used as a foundation to which Fathom OpCo develops upon, allowing us to customize the software based on the specific needs of Fathom. This approach enables faster development of high quality software. We may also face claims alleging noncompliance with open source license terms or infringement or misappropriation of proprietary software. These claims could result in litigation, require us to purchase a costly license or remove the open source software. In addition, if the license terms for open source software that we use change, we may be forced to re-engineer our solutions, incur additional costs or discontinue the sale of certain of our offerings if re-engineering could not be accomplished on a timely basis. Although we

67

monitor our use of open source software to avoid subjecting our offerings to unintended conditions, there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our offerings. We cannot guarantee that we have incorporated open source software in our proprietary software in a manner that will not subject us to liability or in a manner that is consistent with our current policies and procedures.

Compliance-Related Risks

Government regulation of the Internet and e-commerce is evolving, and unfavorable changes or failure by us to comply with these regulations could substantially harm our business and results of operations.

We are subject to general business regulations and laws as well as regulations and laws specifically governing the Internet and e-commerce. Existing and future laws and regulations may impede the growth of the Internet or other online services. These regulations and laws may cover taxation, restrictions on imports and exports, customs, tariffs, user privacy, data protection, pricing, content, copyrights, distribution, electronic contracts and other communications, consumer protection, the provision of online payment services, broadband residential Internet access and the characteristics and quality of the types of custom parts we manufacture or may manufacture in the future. It is not clear how existing laws governing issues such as property use and ownership, sales and other taxes, fraud, libel and personal privacy apply to the Internet and e-commerce, especially where these laws were adopted prior to the advent of the Internet and do not contemplate or address the unique issues raised by the Internet or e-commerce. Those laws that do reference the Internet are being interpreted by the courts and their applicability and reach are therefore uncertain. The costs of compliance with these regulations may increase in the future as a result of changes in the regulations or the interpretation of them. Further, any failures on our part to comply with these regulations may subject us to significant liabilities. Those current and future laws and regulations or unfavorable resolution of these issues may substantially harm our business and results of operations.

Aspects of our business are subject to privacy, data use and data security regulations, which may impact the way we use data to target customers.

Privacy and security laws and regulations may limit the use and disclosure of certain information and require us to adopt certain cybersecurity and data handling practices that may affect our ability to effectively market our manufacturing capabilities to current, past or prospective customers. In many jurisdictions consumers must be notified in the event of a data security breach, and such notification requirements continue to increase in scope and cost. The changing privacy laws in the United States, Europe and elsewhere — including the General Data Protection Regulation (GDPR) in the European Union, which became effective May 25, 2018, and the California Consumer Privacy Act of 2018, which was enacted on June 28, 2018 and became effective on January 1, 2020 — create new individual privacy rights and impose increased obligations, including disclosure obligations, on companies handling personal data. The impact of these continuously evolving laws and regulations could have a material adverse effect on the way we use data to digitally market and pursue our customers.

Our business involves the use of hazardous materials, and we and our suppliers must comply with environmental, health and safety laws and regulations, which can be expensive and restrict how we do business.

Our business involves the controlled storage, use and disposal of hazardous materials. We and our suppliers are subject to federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of these hazardous materials. Although we believe that the safety procedures utilized by us and our suppliers for handling and disposing of these materials comply with the standards prescribed by these laws and regulations, we cannot eliminate the risk of accidental contamination or injury from these materials. In the event of an accident, federal, state or local authorities may curtail the use of these materials and interrupt our business

68

operations. We do not currently maintain hazardous materials insurance coverage. If we are subject to any liability as a result of activities involving hazardous materials, our business and financial condition may be adversely affected and our reputation and brands may be harmed.

If we are unable to meet regulatory quality standards applicable to our manufacturing and quality processes for the parts we manufacture, our business, financial condition or operating results could be harmed.

As a manufacturer of CNC-machined and injection-molded custom parts, we conform to certain international standards, including International Organization for Standardization, or ISO, 9001:2015 for our injection molding facilities and the AS9100:2016 standard for our CNC-machining facilities in Hartland, WI, Pflugerville, TX, Tempe, AZ, Newark, NY. We conform to the ISO 9001:2015 standard for our plastics manufacturing and the AS9100:2016 standard for our metals manufacturing in In Hartland, WI, Pflugerville, TX, Tempe, AZ, and Newark, NY. We conform to the ISO 9001:2015 for our sheet metal custom parts and the AS9100:2016 standards for our CNC-machined custom parts in Hartland, WI, Pflugerville, TX, Tempe, AZ, and Newark, NY. We also conform to international standard ISO 9001:2015 at our manufacturing facilities in Hartland, WI, Oakland, CA, Newark, NY, Pflugerville, TX, Denver, CO, Round Rock, TX, Tempe, AZ, Miami Lakes, FL, and Elk Grove, IL. We conform to the NIST 800-171 standard at our facilities in Oakland, CA and Tempe, AZ. We conform to the ITAR standard at our facilities in Hartland, WI, Oakland, CA, Ithaca, NY, Denver, CO, Tempe, AZ, and Newark, NY. Additionally, we conform to international standard ISO 13485 at our manufacturing facilities in Round Rock, TX and Miami Lakes, FL. If any system inspection reveals that we are not in compliance with applicable standards, registrars may take action against us, including issuing a corrective action request or discontinuing our certifications. If any of these actions were to occur, it could harm our reputation as well as our business, financial condition and operating results.

We are subject to environmental, health and safety laws and regulations related to our operations and the use of our digital manufacturing systems and consumable materials, which could subject us to compliance costs and/or potential liability in the event of non-compliance.

We are subject to environmental laws and regulations governing our manufacturing operations, including, but not limited to, emissions into the air and water and the use, handling, disposal and remediation of hazardous substances. A certain risk of environmental liability is inherent in our production activities. These laws and regulations govern, among other things, the generation, use, storage, registration, handling and disposal of chemicals and waste materials, the emission and discharge of hazardous materials into the ground, air or water, the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals and other waste materials, and the health and safety of our employees. Under these laws, regulations and requirements, we could also be subject to liability for improper disposal of chemicals and waste materials. Accidents or other incidents that occur at our facilities or involve our personnel or operations could result in claims for damages against us. In the event we are found to be financially responsible, as a result of environmental or other laws or by court order, for environmental damages alleged to have been caused by us or occurring on our premises, we could be required to pay substantial monetary damages or undertake extensive remedial obligations. If our operations fail to comply with such laws or regulations, we may be subject to fines and other civil, administrative or criminal sanctions, including the revocation of permits and licenses necessary to continue our business activities. In addition, we may be required to pay damages or civil judgments in respect of third-party claims, including those relating to personal injury (including exposure to hazardous substances that we generate, use, store, handle, transport, manufacture or dispose of), property damage or contribution claims. Some environmental laws allow for strict and joint and several liabilities for remediation costs, regardless of fault. We may be identified as a potentially responsible party under such laws. The amount of any costs, including fines or damages payments that we might incur under such circumstances, could substantially exceed any insurance we have to cover such losses. Any of these events, alone or in combination, could have a material adverse effect on our business, financial condition and results of operations and could adversely affect our reputation.

69

The cost of complying with current and future environmental, health and safety laws applicable to our operations, or the liabilities arising from past releases of, or exposure to, hazardous substances, may result in future expenditures. Any of these developments, alone or in combination, could have an adverse effect on our business, financial condition and results of operations.

We are subject to anti-corruption laws, trade controls, economic sanctions and similar laws and regulations. Our failure to comply with these laws and regulations could subject us to civil, criminal and administrative penalties and harm our reputation.

We service customers located in a number of countries throughout the world. Doing business with foreign customers subjects us to U.S. and other anti-corruption laws and regulations imposed by governments around the world with jurisdiction over such commerce with foreign customers, including the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act 2010, as well as the laws of the countries where we do business. Failure to comply with these anti-corruption laws and regulations could subject us to civil, criminal, and administrative penalties and harm our reputation. We are also subject to various U.S., international, and regional trade laws, including trade and economic sanctions and export controls, imposed by governments around the world with jurisdiction over our commerce with foreign customers. We are also subject to embargoes, sanctions, and trade and export controls imposed by the United States and other governments restricting or prohibiting sales to or transactions with specific persons or jurisdictions or the provision of certain items, based on their classification, to certain jurisdictions or persons or for certain end use purposes. Failure to comply with these embargoes, sanctions, and trade and export controls could subject us to civil, criminal and administrative penalties and harm our reputation. These embargoes, sanctions, and trade and export controls can change rapidly with little to no notice, and therefore, our current and future offerings could become subject to heightened restrictions, which could increase our compliance costs and our risks of potential non-compliance in these areas.

Risks of Being a Public Company

Our management team has limited experience managing a public company and may not successfully manage our transition to public company status.

Most members of our management team have limited experience managing a publicly-traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage our transition to being a public company that is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could harm our business, results of operations and financial condition.

The requirements of being a public company may strain our resources, divert management’s attention and affect its ability to attract and retain qualified board members.

After the completion of the Business Combination, we will be subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and any rules promulgated thereunder, as well as the rules of NYSE. The requirements of these rules and regulations increase our legal and financial compliance costs, make some activities more difficult, time-consuming or costly, and increase demand on its systems and resources. The Sarbanes-Oxley Act requires, among other things, that we maintain effective disclosure controls and procedures and internal controls for financial reporting. In order to maintain and, if required, improve our disclosure controls and procedures and internal control over financial reporting to meet this standard, significant resources and management oversight will be required and, as a result, management’s attention may be diverted from other business concerns. These rules and regulations can also make it more difficult for us to attract and retain qualified independent members of

70

our board of directors. Additionally, these rules and regulations make it more difficult and more expensive for us to obtain director and officer liability insurance. We may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. The increased costs of compliance with public company reporting requirements and our potential failure to satisfy these requirements can have a material adverse effect on our operations, business, financial condition or results of operations.

We have identified material weaknesses in our internal control over financial reporting. resulting from control deficiencies in our IT general controls and process level controls. Failure to achieve and maintain effective internal control over financial reporting could result in our failure to accurately or timely report our financial condition or results of operations, which could have a material adverse effect on our business and stock price.

Upon consummation of the Business Combination, Fathom will be required to comply with the SEC’s rules implementing Sections 302 and 404 of the Sarbanes-Oxley Act, which will require management to certify financial and other information in our quarterly and annual reports and provide an annual management report on the effectiveness of our controls over financial reporting. Although we will be required to disclose changes made in our internal controls and procedures on a quarterly basis, we will not be required to make our first annual assessment of our internal controls over financial reporting pursuant to Section 404 until our annual report on Form 10-K for the fiscal year ending December 31, 2022. This assessment will need to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting, as well as a statement that our independent registered public accounting firm has issued an opinion on the effectiveness of our internal control over financial reporting, provided that our independent registered public accounting firm will not be required to attest to the effectiveness of our internal control over financial reporting until our first annual report required to be filed with the Securities and Exchange Commission, or SEC, following the later of the date we are deemed to be an “accelerated filer” or a “large accelerated filer,” each as defined in the Exchange Act, or the date we are no longer an emerging growth company, as defined in the JOBS Act.

In connection with the audit of our financial statements for the year ended December 31, 2020, we identified material weaknesses relating to our internal control over financial reporting relating to IT general controls, the design of our financial reporting system and the segregation of duties in the financial reporting process. A “material weakness” is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our consolidated financial statements will not be prevented or detected on a timely basis.

Management is working to remediate the material weaknesses by hiring additional qualified accounting and financial reporting personnel, and further evolving our accounting processes. We may not be able to fully remediate these material weaknesses until these steps have been completed and have been operating effectively for a sufficient period of time. We cannot assure you that the measures we have taken to date and plan to take will be sufficient to remediate the material weakness we identified or avoid the identification of additional material weaknesses in the future. If we are not able to maintain effective internal control over financial reporting, our financial statements and related disclosures may be inaccurate, which could have a material adverse effect on our business and our stock price.

Through their ownership of our common stock, “negative control” rights and their rights to nominate directors to our board under the Investor Rights Agreement, the CORE Investors will have substantial influence over our management and policies, and their interests may conflict with ours or yours in the future.

Immediately following completion of the Business Combination and assuming no redemptions by Altimar II’s Public Shareholders, the CORE Investors will beneficially own approximately 46.1% of our Class A common stock and Class B common stock, which will generally vote together as a single class on matters submitted to a vote of our stockholders, including the election of directors (or 64.4% assuming maximum redemptions by Altimar II Public Shareholders (including the Backstop Shares). As a result, the CORE Investors

71

will have the ability to influence our business and affairs through “negative control” rights through their ownership of our Class A common stock combined with certain supermajority voting provisions of the Proposed Charter and Proposed Bylaws, their general ability to vote on the election of directors to our board and the provisions in the Investor Rights Agreement described below. If the other holders of our Class A common stock are dissatisfied with the performance of our board of directors, they have no ability to remove any of our directors, unless for cause and then only upon the affirmative vote of holders of 66-2/3% of our outstanding Class A common stock and Class B common stock, voting as a single class. Assuming maximum redemptions by Altimar II Public Shareholders, approximately 63.7% of the Company’s Common Stock will be held by the CORE Investors. In the event of maximum redemptions by Altimar II Public Shareholders, the Company will be deemed a “controlled company” within the meaning of applicable rules of the NYSE upon the completion of the Business Combination. Under these rules, a company in which more than 50% of the voting power for the election of the company’s directors is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain corporate governance requirements.

In addition, in connection with the Business Combination, we will enter into the Investor Rights Agreement with the CORE Investors which will provide for an initial ten-person board of directors, consisting of nine individuals to be designated by the CORE Investors, and one independent director to be mutually agreed by the CORE Investors and the Sponsor. The CORE Investors will have certain continued nomination rights for a number of directors ranging from the majority of the board of directors to one director, while they beneficially own shares of common stock in excess of certain ownership percentage of the amount owned by the CORE Investors at Closing, as determined in accordance with the Investor Rights Agreement. In addition, for so long as the CORE Investors beneficially own shares of common stock representing at least 5% of the amount owned by the CORE Investors at Closing, the CORE Investors will have the right to designate a person to attend meetings of our board (including any meetings of any committees thereof) in a non-voting observer capacity. See “The Business Combination Agreement – Related Agreements – Investor Rights Agreement and Registration Rights Agreement” for more details with respect to the Investor Rights Agreement.

The CORE Investors and their affiliates engage and will continue to engage in a broad spectrum of activities, including investments in the manufacturing and industrial industries generally, and engage and may continue to engage in the same or similar activities or related lines of business as those in which we are engaged or may engage in, directly or indirectly. In the ordinary course of their business activities, the CORE Investors and their affiliates may engage in activities in which their interests conflict with our interests or those of our other shareholders, such as investing in or advising businesses that directly or indirectly compete with certain portions of our business or are suppliers or partners of ours. Our Proposed Charter will provide that none of the CORE Investors, any of their affiliates or any director who is not employed by us (including any non-employee director who serves as one of our officers in both his director and officer capacities) or its affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which we operate. The CORE Investors and their affiliates also may pursue acquisition opportunities that may be complementary to our business and, as a result, those acquisition opportunities may not be available to us. In addition, the CORE Investors and their affiliates may have an interest in pursuing acquisitions, divestitures and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you.

In certain circumstances, Fathom would qualify as, and would expect to elect to be treated as, a “controlled company” within the meaning of the NYSE listing standards and, as a result, our stockholders may not have certain corporate governance protections that are available to stockholders of companies that are not controlled companies.

Immediately following the completion of the Business Combination and assuming no redemptions by Altimar II’s Public Shareholders, the CORE Investors are expected to beneficially own approximately 46.1% of our Class A common stock and Class B common stock, which will generally vote together as a single class on matters submitted to a vote of our stockholders, including the election of directors (or 63.7% assuming maximum

72

redemptions by Altimar II Public Shareholders (and including the Backstop Shares)). If more than 50% of the voting power for the election of directors of Fathom is held by an individual, a group or another company, including the CORE Investors, Fathom would qualify as a “controlled company” under the NYSE listing requirements. If following the completion of the Business Combination, the CORE Investors control a majority of the voting power of our outstanding capital stock, Fathom would qualify as, and would expect to elect to be treated as, a “controlled company” under the NYSE listing standards and in such case would not be subject to the requirements that would otherwise require us to have: (i) a majority of “independent directors,” as defined under the listing standards of the NYSE; (ii) a nominating committee comprised solely of independent directors; (iii) compensation of our executive officers determined by a majority of the independent directors or a compensation committee comprised solely of independent directors; and (iv) director nominees selected, or recommended for the Board’s selection, either by a majority of the independent directors or a nominating committee comprised solely of independent directors.

In the event that Fathom is categorized as a “controlled company” following the completion of the Business Combination, the CORE Investors may have their interest in Fathom diluted due to future equity issuances by Fathom or their own actions in selling shares of Class A common stock, in each case, which could result in a loss of the “controlled company” exemption under the NYSE listing rules. Fathom would then be required to comply with those provisions of the NYSE listing requirements.

Under SEC Rules, we will be an “emerging growth company” and a “smaller reporting company” and the reduced SEC disclosure requirements applicable to emerging growth companies and smaller reporting companies may make our common stock less attractive to investors.

As a newly public company, we will be “emerging growth company,” as defined in the JOBS Act. As an emerging growth company we may follow reduced disclosure requirements and do not have to make all of the disclosures that public companies that are not emerging growth companies do. We will remain an emerging growth company until the earlier of (a) the last day of the fiscal year in which we have total annual gross revenues of $1.0 billion or more (as adjusted for inflation); (b) the last day of the fiscal year following the fifth anniversary of the date of the completion of the initial public offering of Fathom; (c) the date on which we have issued more than $1 billion in nonconvertible debt during the previous three years; or (d) the date on which we are deemed to be a large accelerated filer under the rules of the SEC, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30. For so long as we remain an emerging growth company, we are permitted and intend to rely on exemptions from certain disclosure requirements that are applicable to other public companies that are not emerging growth companies. These exemptions include:

• not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act;

• not being required to comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (i.e., an auditor discussion and analysis);

• reduced disclosure obligations regarding executive compensation in our periodic reports, proxy statements and registration statements; and

• exemptions from the requirements of holding a nonbinding advisory vote of stockholders on executive compensation, stockholder approval of any golden parachute payments not previously approved and having to disclose the ratio of the compensation of our chief executive officer to the median compensation of our employees.

In addition, the JOBS Act provides that an emerging growth company can take advantage of an extended transition period for complying with new or revised accounting standards. This allows an emerging growth

73

company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use the extended transition period for complying with new or revised accounting standards; and as a result of this election, our financial statements may not be comparable to companies that comply with public company effective dates.

We may choose to take advantage of some, but not all, of the available exemptions for emerging growth companies. We cannot predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock and our share price may be more volatile.

In order to satisfy our obligations as a public company, we will need to hire qualified accounting and financial personnel with appropriate public company experience.

As a newly public company, we will need to establish and maintain effective disclosure and financial controls and make changes in our corporate governance practices. We may need to hire additional accounting and financial personnel with appropriate public company experience and technical accounting knowledge, and it may be difficult to recruit and retain such personnel. Even if we are able to hire appropriate personnel, our existing operating expenses and operations will be impacted by the direct costs of their employment and the indirect consequences related to the diversion of management resources from research and development efforts.

The Company may be subject to securities litigation, which is expensive and could divert management attention.

Following the Business Combination, the per share price of the Class A common stock may be volatile and, in the past, companies that have experienced volatility in the market price of their stock have been subject to securities litigation, including class action litigation. Litigation of this type could result in substantial costs and diversion of management’s attention and resources, which could have a material adverse effect on our business, financial condition, and results of operations. Any adverse determination in litigation could also subject the Company to significant liabilities.

Because the Company will become a publicly traded company by means other than a traditional underwritten initial public offering, the Company’s stockholders may face additional risks and uncertainties.

Because the Company will become a publicly traded company by means of consummating the Business Combination rather than by means of a traditional underwritten initial public offering, there is no independent third-party underwriter selling the shares of the Company’s Class A common stock, and, accordingly, the Company’s stockholders will not have the benefit of an independent review and investigation of the type normally performed by an unaffiliated, independent underwriter in a public securities offering. Due diligence reviews typically include an independent investigation of the background of the company, any advisors and their respective affiliates, review of the offering documents and independent analysis of the plan of business and any underlying financial assumptions. Although Altimar II performed a due diligence review and investigation of Fathom OpCo in connection with the Business Combination, the lack of an independent due diligence review and investigation increases the risk of investment in the Company because Altimar II’s due diligence review and investigation may not have uncovered facts that would be important to a potential investor.

In addition, because the Company will not become a publicly traded company by means of an traditional underwritten initial public offering, security or industry analysts may not provide, or be less likely to provide, coverage of the Company. Investment banks may also be less likely to agree to underwrite secondary offerings on behalf of the Company than they might otherwise be if the Company became a publicly traded company by means of a traditional underwritten initial public offering because they may be less familiar with the Company as a result of more limited coverage by analysts and the media. The failure to receive research coverage or support in the market for the Company’s Class A common stock could have an adverse effect on the Company’s ability to develop a liquid market for the Company’s Class A common stock.

Risks Related to our Structure and Governance

Upon completion of the Business Combination, the rights of holders of Fathom’s common stock arising under the DGCL will differ from and may be less favorable to the rights of holders of Altimar II’s ordinary shares arising under Cayman Islands law.

Upon completion of the Business Combination, the rights of holders of Fathom’s common stock will arise under the DGCL. The DGCL contains provisions that differ in some respects from those in the Cayman Islands Companies Act, and, therefore, some rights of holders of Fathom’s common stock could differ from the rights that holders of Altimar II ordinary shares currently possess. For instance, while class action lawsuits are generally not available to shareholders under Cayman Islands law, such actions are generally available under Delaware law. This change could increase the likelihood that Fathom becomes involved in costly litigation, which could have a material adverse effect on Fathom

For a more detailed description of the rights of holders of Fathom’s common stock under the DGCL and how they may differ from the rights of holders of Altimar II ordinary shares under Cayman Islands law, please see the section entitled “The Domestication Proposal — Comparison of Corporate Governance and Shareholders.”

Delaware law, the Proposed Charter and Proposed Bylaws will contain certain provisions, including anti-takeover provisions, that limit the ability of stockholders to take certain actions and could delay or discourage takeover attempts that stockholders may consider favorable.

The Proposed Charter and Proposed Bylaws that will be in effect upon completion of the Business Combination differ from the Amended and Restated Memorandum and Articles of Association. Among other differences, the Proposed Charter and the DGCL contain provisions that could have the effect of rendering more difficult, delaying, or preventing an acquisition deemed undesirable by the Fathom Board and therefore depress the trading price of Fathom’s Class A common stock. These provisions could also make it difficult for stockholders to take certain actions, including electing directors who are not nominated by the current members of the Fathom Board or taking other corporate actions, including effecting changes in management. Among other things, the Proposed Charter and Proposed Bylaws include provisions regarding:

• a classified board of directors with three-year staggered terms, which could delay the ability of stockholders to change the membership of a majority of the Fathom Board;

• the ability of the Fathom Board to issue shares of preferred stock, including “blank check” preferred stock and to determine the price and other terms of those shares, including preferences and voting rights, without stockholder approval, which could be used to significantly dilute the ownership of a hostile acquirer;

• the limitation of the liability of, and the indemnification of, Fathom’s directors and officers;

• the right of the Fathom Board to elect a director to fill a vacancy created by the expansion of the Fathom Board or the resignation, death or removal of a director, which prevents stockholders from being able to fill vacancies on the Fathom Board;

• the requirement that directors may only be removed from the Fathom Board for cause;

• the requirement that a special meeting of stockholders may be called only by the Fathom Board or the chairman of the Fathom Board, which could delay the ability of stockholders to force consideration of a proposal or to take action, including the removal of directors;

• controlling the procedures for the conduct and scheduling of the Fathom Board and stockholder meetings;

• the ability of the Fathom Board to amend the Proposed Bylaws, which may allow the Fathom Board to take additional actions to prevent an unsolicited takeover and inhibit the ability of an acquirer to amend the Proposed Bylaws to facilitate an unsolicited takeover attempt; and

75

• advance notice procedures with which stockholders must comply to nominate candidates to the Fathom Board or to propose matters to be acted upon at a stockholders’ meeting, which could preclude stockholders from bringing matters before annual or special meetings of stockholders and delay changes in the composition of the Fathom Board and also may discourage or deter a potential acquirer from conducting a solicitation of proxies to elect the acquirer’s own slate of directors or otherwise attempting to obtain control of the Company.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in the Fathom board or management.

In addition, as a Delaware corporation, Fathom will generally be subject to provisions of Delaware law, including the DGCL, although Fathom will elect not to be governed by Section 203 of the DGCL.

Any provision of the Proposed Charter, Proposed Bylaws or Delaware law that has the effect of delaying or preventing a change in control could limit the opportunity for stockholders to receive a premium for their shares of Fathom’s capital stock and could also affect the price that some investors are willing to pay for Fathom’s common stock.

The form of the Proposed Charter is attached as Annex A to this proxy statement/prospectus, and the form of the Proposed Bylaws is attached as Annex B to this proxy statement/prospectus, and we urge you to read each of them.

In addition, the provisions of the Investor Rights Agreement, as described herein, provide the stockholders party thereto with certain board representation and other consent rights that could also have the effect of delaying or preventing a change in control.

The Proposed Charter will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by Fathom’s stockholders, which could limit Fathom’s stockholders’ ability to obtain a favorable judicial forum for disputes with Fathom or its directors, officers or other employees.

The Proposed Charter will provide that, unless Fathom consents in writing to the selection of an alternative forum, (a) any derivative action or proceeding brought on behalf of Fathom, (b) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of Fathom to Fathom or Fathom’s stockholders, or any claim for aiding and abetting such alleged breach, (c) any action asserting a claim against Fathom or any current or former director, officer, other employee, agent or stockholder of Fathom (i) arising pursuant to any provision of the DGCL, the Proposed Charter (as it may be amended or restated) or the Proposed Bylaws or (ii) as to which the DGCL confers jurisdiction on the Delaware Court of Chancery or (d) any action asserting a claim against Fathom or any current or former director, officer, other employee, agent or stockholder of Fathom governed by the internal affairs doctrine of the law of the State of Delaware shall, as to any action in the foregoing clauses (a) through (b), to the fullest extent permitted by law, be solely and exclusively brought in the Delaware Court of Chancery; provided, however, that the foregoing shall not apply to any claim arising under federal securities laws, including the Securities Act as to which the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum. Notwithstanding the foregoing, the provisions of Article XI of the Proposed Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act, or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Further, Section 22 of the Securities Act of 1933 creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by that act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce this forum selection provision as written as to claims arising under the Securities Act.

This choice-of-forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with Fathom or its directors, officers, stockholders, agents or other employees, which

76

may discourage such lawsuits. Alternatively, if a court were to find this provision of the Proposed Charter inapplicable or unenforceable with respect to one or more of the specified types of actions or proceedings, Fathom may incur additional costs associated with resolving such matters in other jurisdictions, which could materially and adversely affect Fathom’s business, financial condition and results of operations and result in a diversion of the time and resources of Fathom’s management and board of directors.

The Proposed Charter will not limit the ability of the CORE Investors to compete with us.

The CORE Investors and their affiliates engage in a broad spectrum of activities, including investments in the financial services and technology industries. In the ordinary course of their business activities, the CORE Investors and their affiliates may engage in activities where their interests conflict with Fathom’s interests or those of its stockholders. The Proposed Charter will provide that none of the CORE Investors, any of their affiliates or any director who is not employed by Fathom (including any non-employee director who serves as one of its officers in both his director and officer capacities) or its affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which Fathom operates. The CORE Investors and their affiliates also may pursue, in their capacities other than as directors of Fathom, acquisition opportunities that may be complementary to Fathom’s business, and, as a result, those acquisition opportunities may not be available to Fathom. In addition, the CORE Investors may have an interest in pursuing acquisitions, divestitures and other transactions that, in their judgment, could enhance their investment, even though such transactions might involve risks to you.

Risks Related to the Business Combination and Altimar II

Our Sponsor has agreed to vote in favor of the Business Combination, regardless of how our Public Shareholders vote.

Unlike some other blank check companies in which the initial shareholders agree to vote their shares in accordance with the majority of the votes cast by the public shareholders in connection with an initial business combination, Sponsor has agreed, among other things, (i) from the date of the Business Combination Agreement until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, to not redeem any Class A ordinary shares (or, if applicable, shares of Altimar II Class A common stock) held by it and (ii) prior to the consummation of Business Combination or the termination of the Business Combination Agreement, to vote or cause to be voted, all of the Altimar II shares beneficially owned by Sponsor, at every meeting of the shareholders of Altimar II at which such matters are considered and at every adjournment or postponement thereof: (1) in favor of (A) the Business Combination and the Business Combination Agreement and the other transactions contemplated thereby (including any proposals recommended by Altimar II’s Board of Directors in connection with the Business Combination) and (B) any proposal to adjourn or postpone such meeting of shareholders to a later date if there are not sufficient votes to approve the Business Combination; (2) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of Altimar II under the Business Combination Agreement; and (3) against (A) any proposal or offer from any person concerning (I) a merger, consolidation, liquidation, recapitalization, share exchange or other business combination transaction involving Altimar II, or (II) the issuance or acquisition of shares of capital stock or other Altimar II equity securities (other than as contemplated or permitted by the Business Combination Agreement); and (B) any action, proposal, transaction or agreement that would reasonably be expected to (x) impede the fulfillment of Altimar II’s conditions under the Business Combination Agreement or change in any manner the voting rights of any class of Altimar II’s shares or (y) result in a breach of any covenant, representation or warranty or other obligation or agreement of Sponsor contained in the Forfeiture and Support Agreement.

As of the date of this proxy statement/prospectus, the Sponsor owns approximately 20% of the issued and outstanding ordinary shares.

77

If the conditions to the Business Combination Agreement are not met, the Business Combination may not occur.

Even if the Business Combination Agreement is approved by the shareholders of Altimar II, specified conditions must be satisfied or waived before the parties to the Business Combination Agreement are obligated to complete the Business Combination, including, among other things, certain approvals. For a list of the material closing conditions contained in the Business Combination Agreement, see the section entitled “The Business Combination Agreement — Conditions to Closing of the Business Combination Agreement.” Altimar II and Fathom may not satisfy all of the closing conditions in the Business Combination Agreement. If the closing conditions are not satisfied or waived, the Business Combination will not occur, or will be delayed pending later satisfaction or waiver, and such delay may cause Altimar II and Fathom OpCo to each lose some or all of the intended benefits of the Business Combination.

Some of Altimar II’s officers and directors may have conflicts of interest that may influence or have influenced them to support or approve the Business Combination without regard to your interests or in determining whether Fathom is appropriate for Altimar II’s initial business combination.

The personal and financial interests of Altimar II’s Sponsor, officers and directors may influence or have influenced their motivation in identifying and selecting a target for the Business Combination, their support for completing the Business Combination and the operation of Fathom following the Business Combination.

Altimar II’s Sponsor and independent directors own 8,450,000 and 175,000 Class B ordinary shares, respectively, which were initially acquired prior to Altimar II’s IPO for an aggregate purchase price of $0.003 per share and Altimar II’s officers have pecuniary interests in such ordinary shares through indirect ownership interests in the Sponsor. Such shares had an aggregate market value of approximately $                based on the last sale price of $                per share on the NYSE on        , the record date. In addition, the Sponsor purchased an aggregate of 9,900,000 Private Placement Warrants, each exercisable for one ordinary share of Altimar II at $11.50 per share, for a purchase price of $9,900,000, or $1.00 per warrant. Altimar II’s Amended and Restated Memorandum and Articles of Association require Altimar II to complete an initial business combination (which will be the Business Combination should it occur) within 24 months from the closing of the IPO, or February 9, 2023 (the “Combination Period”) (unless Altimar II submits and its shareholders approve an extension of such date). If the Business Combination is not completed and Altimar II is forced to wind up, dissolve and liquidate in accordance with the Amended and Restated Memorandum and Articles of Association, the 8,450,000 and 175,000 Class B ordinary shares currently held by Altimar II’s Sponsor and independent directors, respectively, and the Private Placement Warrants held by the Sponsor will be worthless (as the holders have waived liquidation rights with respect to such ordinary shares).

Altimar II’s Sponsor, directors and officers, and their respective affiliates have incurred significant out-of-pocket expenses in connection with performing due diligence on suitable targets for business combinations and the negotiation of the Business Combination. At the Closing of the Business Combination, Altimar II’s Sponsor, directors and officers, and their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on Altimar II’s behalf such as identifying potential target businesses and performing due diligence on suitable targets for business combinations. As of September 30, 2021, Sponsor and its affiliates are awaiting reimbursement from Altimar II for approximately $12,570 in out-of-pocket expenses paid by Sponsor and its affiliates on behalf of Altimar II. If an initial business combination is not completed prior to February 9, 2023, Altimar II’s Sponsor, directors and officers, or any of their respective affiliates will not be eligible for any such reimbursement.

Pre-existing relationships between participants in the Business Combination and the related transactions or their affiliates could give rise to actual or perceived conflicts of interest in connection with the Business Combination.

Certain of the participants in the Business Combination and the PIPE financing or their affiliates have pre-existing relationships that could give rise to actual or perceived conflicts of interest in connection with the

78

Business Combination and related transactions. For example, certain of the PIPE investors are associated with entities affiliated with Sponsor and with the CORE Investors, respectively. See “Certain Relationships and Related Party Transactions.”

The same investment banks are acting as co-placement agents to Altimar II in connection with the PIPE Investment and as financial advisors to Fathom OpCo in connection with the Business Combination, and will be paid fees with respect to each role and deferred underwriting compensation from any such bank’s role as an underwriter to Altimar II in its initial public offering upon the consummation of the Business Combination, which might result in actual or potential conflicts of interest.

Fathom OpCo has engaged each of J.P. Morgan Securities LLC (“J.P. Morgan”)’s M&A Advisory Group and Stifel, Nicolaus & Company (“Stifel”) to act as Fathom OpCo’s financial advisors in connection with the Business Combination. Altimar II has engaged (i) J.P. Morgan’s Equity Capital Markets Group to act as co-placement agent and capital markets advisor and (ii) Stifel to act as co-placement agent (together, in their capacity as placement agents, the “Placement Agents”) in connection with the PIPE Investment. In addition, J.P. Morgan acted as an underwriter to Altimar II in its initial public offering. Pursuant to these engagements, (i) Fathom OpCo will pay J.P. Morgan and Stifel advisory fees at the Closing; (ii) Altimar II will pay J.P. Morgan and Stifel placement agent fees upon the consummation of the PIPE Investment and (iii) Altimar II will pay J.P. Morgan deferred underwriting compensation at the Closing.

Because (i) J.P. Morgan and Stifel will only be paid the advisory fees for acting as Fathom OpCo’s financial advisors upon the consummation of the Business Combination; (ii) J.P. Morgan will only be paid deferred underwriting compensation upon the consummation of the Business Combination; and (iii) J.P. Morgan and Stifel will only be paid the placement agent fees upon the consummation of the PIPE Investment, each of J.P. Morgan and Stifel have financial interests in both the PIPE Investment and the Business Combination being consummated. Such interests may have presented, and may in the future present, one or more conflicts of interest. You should consider the various roles of the investment banks with respect to the Business Combination in evaluating “Proposal No. 1—The Business Combination Proposal” and the other proposals.

The exercise of Altimar II’s directors’ and executive officers’ discretion in agreeing to changes or waivers in the terms of the Business Combination may result in a conflict of interest when determining whether changes to the terms of the Business Combination or waivers of conditions are appropriate and in Altimar II’s shareholders’ best interest.

In the period leading up to the closing of the Business Combination, events may occur that, pursuant to the Business Combination Agreement, may require Altimar II to agree to amend the Business Combination Agreement, to consent to certain actions taken by Fathom OpCo or to waive rights that Altimar II is entitled to under the Business Combination Agreement. Such events could arise because of changes in the course of Fathom OpCo’s business, a request by Fathom OpCo to undertake actions that would otherwise be prohibited by the terms of the Business Combination Agreement or the occurrence of other events that would have a material adverse effect on Fathom OpCo’s business and would entitle Altimar II to terminate the Business Combination Agreement. In any of such circumstances, it would be at Altimar II’s discretion, acting through its board of directors, to grant its consent or waive those rights. The existence of financial and personal interests of one or more of the directors described in the preceding risk factors may result in a conflict of interest on the part of such director(s) between what he or they may believe is best for Altimar II and its shareholders and what he or they may believe is best for himself or themselves in determining whether or not to take the requested action. As of the date of this proxy statement/prospectus, Altimar II does not believe there will be any changes or waivers that Altimar II’s directors and executive officers would be likely to make after shareholder approval of the Business Combination Proposal has been obtained. While certain changes could be made without further shareholder approval, Altimar II will circulate a new or amended proxy statement/prospectus and resolicit Altimar II’s shareholders if changes to the terms of the transaction that would have a material impact on its shareholders are required prior to the vote on the Business Combination Proposal.

79

A portion of our total outstanding shares are restricted from immediate resale but may be sold into the market in the near future. This could cause the market price of our Class A common stock to drop significantly, even if Fathom’s business is doing well.

Sales of a substantial number of shares of the Class A common stock in the public market could occur at any time. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of the Class A common stock. While the Legacy Fathom Owners and the Altimar II Founders have agreed, and will continue to be subject, to certain restrictions regarding the transfer of the Class A common stock, these shares may be sold after the expiration of the applicable restrictions. Fathom may file one or more registration statements prior to or shortly after the closing of the Business Combination to provide for the resale of such shares from time to time. As restrictions on resale end and the registration statements are available for use, the market price of the Class A common stock could decline if the holders of currently restricted shares sell them or are perceived by the market as intending to sell them.

If the sale of some or all of the PIPE Investment fails to close and sufficient shareholders exercise their Redemption Rights in connection with the Business Combination, Altimar II may lack sufficient funds to consummate the Business Combination.

In connection with the Business Combination Agreement, Altimar II and Fathom OpCo entered into the PIPE Subscription Agreements with the PIPE Investors which provide for the purchase of an aggregate of up to 9,000,000 shares of Class A common stock (the “PIPE Securities”) following the Domestication and immediately prior to the Closing in a private placement to close concurrently with, and contingent upon, the closing of the Business Combination, for a purchase price of $10.00 per share, or an aggregate of up to $90.0 million. Purchases of 8,000,000 of such shares will be made regardless of whether any Class A ordinary shares are redeemed by Altimar II’s Public Shareholders and up to 1,000,000 of such shares will be purchased pursuant to the Backstop Investment, if applicable. The proceeds from the sale of the PIPE Securities will be part of the Business Combination consideration. In addition, prior to giving effect to the exercise of any Redemption Rights, the Trust Account has approximately $345,000,000, plus accrued interest since the completion of the Altimar II IPO. However, if the sale of the PIPE Securities does not close by reason of the failure by some or all of the PIPE Investors to fund the purchase price for their PIPE Securities, for example, and a sufficient number of holders of Class A ordinary shares exercise their redemption rights in connection with the Business Combination, we may lack sufficient funds to consummate the Business Combination. Additionally, the PIPE Investors’ obligations to purchase the PIPE Securities are subject to termination prior to the closing of the sale of the PIPE Securities by mutual written consent of Altimar II, Fathom OpCo and each of the PIPE Investors, or if the Business Combination is not consummated on or before December 31, 2021. The PIPE Investors’ obligations to purchase the PIPE Securities are subject to fulfillment of customary closing conditions, including that the Business Combination must be consummated substantially concurrently with, and immediately following, the purchase of the PIPE Securities. In the event of any such failure to fund, any obligation is so terminated or any such condition is not satisfied and not waived, we may not be able to obtain additional funds to account for such shortfall on terms favorable to us or at all. Any such shortfall would also reduce the amount of funds that we have available for working capital of the post-business combination Company. While the PIPE Investors represented to us that they have sufficient funds to satisfy their obligations under the PIPE Subscription Agreements, we have not obligated them to reserve funds for such obligations. The Business Combination Agreement includes a minimum condition to Fathom OpCo’s obligation to consummate the Business Combination that at least $90.0 million in cash is available to Altimar II from the PIPE Investment together with any cash remaining in the Trust Account after giving effect to any exercise of Redemption Rights by Altimar II’s shareholders.

For information on the consequences if the Business Combination is not completed or must be restructured, please see the section of this proxy statement/prospectus entitled “Risk Factors — Risks Related to the Business Combination and Altimar II.”

80

Subsequent to the completion of the Business Combination, Fathom may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on its financial condition and its share price, which could cause you to lose some or all of your investment.

Altimar II cannot assure you that the due diligence Altimar II has conducted on Fathom will reveal all material issues that may be present with regard to Fathom, or that factors outside of Altimar II’s or Fathom’s control will not later arise. As a result of unidentified issues or factors outside of Altimar II’s or Fathom’s control, Fathom may be forced to later write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in reporting losses. Even if Altimar II’s due diligence successfully identifies certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with the preliminary risk analysis conducted by Altimar II. Even though these charges may be non-cash items that would not have an immediate impact on Fathom’s liquidity, the fact that Fathom reports charges of this nature could contribute to negative market perceptions about Fathom or its securities. In addition, charges of this nature may cause Fathom to violate leverage or other covenants to which it may be subject. Accordingly, any shareholders who choose to remain shareholders following the Business Combination could suffer a reduction in the value of their shares from any such write-down or write-downs.

Altimar II’s Public Shareholders will experience dilution due to the issuance to Legacy Fathom Owners of securities entitling them to a significant voting stake in Fathom.

Based upon the assumptions described under the section entitled “Unaudited Pro Forma Condensed Combined Financial Information,” Altimar II’s current Public Shareholders, the PIPE Investors and the Altimar II Founders would hold in the aggregate approximately 25.5%, 5.9% and 3.5%, respectively, of the outstanding economic interests in Fathom (in each case, assuming no redemptions by Altimar II’s Public Shareholders), following the consummation of the Business Combination. Assuming maximum redemptions by Altimar II’s Public Shareholders and subject to the other assumptions described under the section entitled “Unaudited Pro Forma Condensed Combined Financial Information”, Altimar II’s non-redeeming Public Shareholders, the PIPE Investors (including the Backstop Investors) and the Altimar II Founders would hold in the aggregate approximately 0%, 6.7% and 3.5%, respectively, of the outstanding economic interests in Fathom following the consummation of the Business Combination. For purposes of the foregoing Maximum Redemptions presentation only, PIPE Investors also includes the Backstop Investors pursuant to the CORE Backstop Agreement. Without limiting the other assumptions described under the section entitled “Unaudited Pro Forma Condensed Combined Financial Information,” these ownership percentages do not take into account:

• any warrants or options to purchase the Class A common stock, including the Public Warrants and the Private Placement Warrants, that will be outstanding following the Business Combination;

• any equity awards that may be issued by Fathom; and

• the Earnout Shares or the Sponsor Earnout Shares.

If any shares of Class A common stock are redeemed in connection with the Business Combination, the percentage of Fathom’s outstanding voting stock held by the current holders of Altimar II will decrease relative to the percentage held if none of the Class A ordinary shares are redeemed. To the extent that any of the outstanding Public Warrants and Private Placement Warrants are exercised for shares of Class A common stock, Altimar II’s existing shareholders may experience substantial dilution. The Altimar II Founders’ pro forma economic ownership of Fathom (assuming exercise of the Public Warrants and the Private Placement Warrants) is set forth below:

	Assuming No Redemptions								Assuming Maximum Redemptions(1)
	Shares		Ownership %(2)			Voting %(2)			Shares		Ownership %(2)			Voting %(2)
Altimar II Founders(3)		14,670,000		9.6	%		9.6	%		14,670,000		9.6	%		9.6	%

81

(1) This presentation assumes maximum redemptions in which the Altimar II Public Shareholders redeem all 34,500,000 outstanding shares of Altimar II’s Class A ordinary shares.

(2) Percentage calculations assume the exercise and conversion of: (i) 8,625,000 Public Warrants and (ii) 9,900,000 Private Placement Warrants held by Sponsor. Percentage calculations exclude: (i) the Earnout Shares and the Sponsor Earnout Shares (each as defined herein), all of which will be unvested as of the Closing and (ii) shares and awards issuable under the 2021 Omnibus Plan.

(3) Holdings of Altimar II Founders consists of (i) the shares of Class A common stock held by the Sponsor and the other Altimar II Founders upon automatic conversion of their Class B ordinary shares into Class C common stock as a result of the Business Combination which shares of Class C common stock will then convert into Class A common stock prior to pro rata forfeiture by the Altimar II Founders of an aggregate of 2,587,500 shares of Class A common stock and (ii) 9,900,000 shares issuable upon exercise of the Private Placement Warrants held by Sponsor. Holdings of Sponsor excludes 1,267,500 shares of Class A common stock held by Sponsor that constitute Sponsor Earnout Shares (as defined herein).

Altimar II Public Shareholders who do not redeem their Class A ordinary shares will have a reduced ownership and voting interest after the Business Combination and will exercise less influence over management of Fathom.

Upon the issuance of Fathom Class A and Class B common stock in connection with the Business Combination, the percentage ownership of Public Shareholders who do not redeem their shares of Class A ordinary shares will be diluted. The percentage of the Fathom Class A common stock that will be owned by Public Shareholders as a group will vary based on the number of Class A ordinary shares for which the holders thereof request redemption in connection with the Business Combination. To illustrate the potential ownership percentages of Public Shareholders under different redemption levels, based on the number of issued and outstanding shares of Altimar II Class A and Class B ordinary shares on September 30, 2021, and based on the Fathom Class A and Class B Common Stock expected to be issued in the Business Combination and the Class A Common Stock expected to be issued as part of the PIPE Investment, non-redeeming Public Shareholders, as a group, will own:

• if there are no redemptions of Public Shares, 26% of Fathom’s Common Stock expected to be outstanding immediately after the Business Combination;

• if there are redemptions of 50% of maximum redemptions, 13% of Fathom’s Common Stock expected to be outstanding immediately after the Business Combination; or

• if there are maximum redemptions, 0% of Fathom’s Common Stock expected to be outstanding immediately after the Business Combination.

Because of this, Public Shareholders, as a group, will have less influence on the board of directors, management and policies of Fathom than they now have on the board of directors, management and policies of Altimar II. For further discussion of the assumptions underlying the no, low, high and maximum redemptions scenarios set forth above, please see “Unaudited Pro Forma Condensed Combined Financial Information.”

The ownership percentage with respect to Fathom following the Business Combination does not take into account the following potential issuances of securities, which will result in further dilution to Public Shareholders who do not redeem their Public Shares:

• the issuance of up to 8,625,000 shares upon exercise of the Public Warrants at a price of $11.50 per share;

• the issuance of up to 9,900,000 shares upon exercise of the Private Placement Warrants held by the Sponsor at a price of $11.50 per share;

• the issuance of the Earnout Shares and the Sponsor Earnout Shares (each as defined herein); and

• the issuance of shares under the 2021 Omnibus Plan.

82

If all such shares were issued immediately after the Business Combination, based on the number of issued and outstanding shares of Altimar II Class A and Class B ordinary shares, and based on the Class A and Class B common stock expected to be issued in the Business Combination and the Class A common stock expected to be issued as part of the PIPE Investment, non-redeeming Public Shareholders, as a group, would own:

• if there are no redemptions of Public Shares, 25% of Fathom’s Common Stock outstanding assuming all such shares were issued immediately after the Business Combination;

• if there are redemptions of 50% of maximum redemptions, 15% of Fathom’s Common Stock outstanding assuming all such shares were issued immediately after the Business Combination;

or

• if there are maximum redemptions of the outstanding Public Shares, 5% of Fathom’s Common Stock outstanding assuming all such shares were issued immediately after the Business Combination.

Altimar II has not obtained an opinion from an independent investment banking firm or another independent firm, and consequently, you may have no assurance from an independent source that the terms of the Business Combination are fair to Altimar II from a financial point of view.

The Altimar II Board did not obtain a third-party valuation or fairness opinion in connection with their determination to approve the Business Combination. Altimar II is not required to obtain an opinion from an independent investment banking firm that is a member of FINRA or from another independent firm that the price it is paying is fair to Altimar II from a financial point of view. In analyzing the Business Combination, the Altimar II Board and Altimar II’s management conducted due diligence on Fathom OpCo and researched the industry in which Fathom OpCo operates and concluded that the Business Combination was in the best interest of its shareholders. Accordingly, Altimar II’s shareholders will be relying solely on the judgment of the Altimar II Board in determining the value of the Business Combination, and the Altimar II Board may not have properly valued such business. The lack of a third-party valuation or fairness opinion may also lead an increased number of shareholders to vote against the Business Combination or demand redemption of their shares, which could potentially impact our ability to consummate the Business Combination. For more information about our decision-making process, see the section entitled “The Business Combination Agreement — Altimar II’s Board of Director’s Reasons for the Approval of the Business Combination.”

If the Adjournment Proposal is not approved, and an insufficient number of votes have been obtained to authorize the consummation of the Business Combination and the Domestication, the Altimar II board of directors will not have the ability to adjourn the Special Meeting to a later date in order to solicit further votes, and, therefore, the Business Combination will not be approved, and, therefore, the Business Combination may not be consummated.

The Altimar II Board is seeking approval to adjourn the Special Meeting to a later date or dates if, at the Special Meeting, based upon the tabulated votes, there are insufficient votes to approve each of the Condition Precedent Proposals or they determine that one or more of the closing conditions under the Business Combination Agreement is not satisfied or waived. If the Adjournment Proposal is not approved, the Altimar II Board will not have the ability to adjourn the Special Meeting to a later date and, therefore, will not have more time to solicit votes to approve the Condition Precedent Proposals. In such event, the Business Combination would not be completed.

The unaudited pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” may not be representative of Fathom’s results if the Business Combination is completed.

Altimar II and Fathom OpCo currently operate as separate companies and have had no prior history as a combined entity. The pro forma financial information included in this proxy statement/prospectus is presented

for informational purposes only and is not necessarily indicative of the financial position or results of operations that would have actually occurred had the Business Combination been completed at or as of the dates indicated, nor is it indicative of the future operating results or financial position of Fathom OpCo. The pro forma statement of operations does not reflect future nonrecurring charges resulting from the Business Combination. The unaudited pro forma financial information does not reflect future events that may occur after the Business Combination and does not consider potential impacts of future market conditions on revenues or expenses. The pro forma financial information included in the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” has been derived from Altimar II’s and Fathom OpCo’s historical financial statements and certain adjustments and assumptions have been made regarding Fathom after giving effect to the Business Combination. There may be differences between preliminary estimates in the pro forma financial information and the final acquisition accounting, which could result in material differences from the pro forma information presented in this proxy statement/prospectus in respect of the estimated financial position and results of operations of Fathom.

In addition, the assumptions used in preparing the pro forma financial information may not prove to be accurate and other factors may affect Fathom’s financial condition or results of operations following the Closing. Any potential decline in Fathom’s financial condition or results of operations may cause significant variations in the stock price of Fathom.

During the pendency of the Business Combination, Altimar II will not be able to solicit, initiate or take any action to facilitate or encourage any inquiries or the making, submission or announcement of, or enter into a business combination with another party because of restrictions in the Business Combination Agreement.

During the pendency of the Business Combination, Altimar II will not be able to enter into a business combination with another party because of non-solicitation provisions in the Business Combination Agreement which prohibit Altimar II from soliciting other business combinations. If the Business Combination is not completed, these non-solicitation provisions will make it more difficult to complete an alternative business combination following the termination of the Business Combination Agreement due to the passage of time during which these provisions have remained in effect.

Because Altimar II is incorporated under the laws of the Cayman Islands, in the event the Business Combination is not completed, you may face difficulties in protecting your interests, and your ability to protect your rights through the U.S. Federal courts may be limited.

Because Altimar II is currently incorporated under the laws of the Cayman Islands, you may face difficulties in protecting your interests and your ability to protect your rights through the U.S. Federal courts may be limited prior to the Domestication. Altimar II is currently an exempted company under the laws of the Cayman Islands. As a result, it may be difficult for investors to effect service of process within the United States upon Altimar II’s directors or officers, or enforce judgments obtained in the United States courts against Altimar II’s directors or officers.

Until the Domestication is effected, Altimar II’s corporate affairs are governed by the Amended and Restated Memorandum and Articles of Association, the Cayman Islands Companies Act and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of its directors to Altimar II under the laws of the Cayman Islands are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from English common law, the decisions of whose courts are of persuasive authority, but are not binding on a court in the Cayman Islands. The rights of Altimar II’s shareholders and the fiduciary responsibilities of its directors under Cayman Islands law are different from what they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a different body of securities laws as compared to the United States, and certain states, such as Delaware, may have more fully developed and

84

judicially interpreted bodies of corporate law. In addition, Cayman Islands companies may not have standing to initiate a shareholders derivative action in a Federal court of the United States.

The courts of the Cayman Islands are unlikely (i) to recognize or enforce against Altimar II judgments of courts of the United States predicated upon the civil liability provisions of the federal securities laws of the United States or any state; and (ii) in original actions brought in the Cayman Islands, to impose liabilities against Altimar II predicated upon the civil liability provisions of the federal securities laws of the United States or any state, so far as the liabilities imposed by those provisions are penal in nature. In those circumstances, although there is no statutory enforcement in the Cayman Islands of judgments obtained in the United States, the courts of the Cayman Islands will recognize and enforce a foreign money judgment of a foreign court of competent jurisdiction without retrial on the merits based on the principle that a judgment of a competent foreign court imposes upon the judgment debtor an obligation to pay the sum for which judgment has been given provided certain conditions are met. For a foreign judgment to be enforced in the Cayman Islands, such judgment must be final and conclusive and for a liquidated sum, and must not be in respect of taxes or a fine or penalty, inconsistent with a Cayman Islands judgment in respect of the same matter, impeachable on the grounds of fraud or obtained in a manner, or be of a kind the enforcement of which is, contrary to natural justice or the public policy of the Cayman Islands (awards of punitive or multiple damages may well be held to be contrary to public policy). A Cayman Islands court may stay enforcement proceedings if concurrent proceedings are being brought elsewhere.

The Public Shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the Altimar II Board or controlling shareholders than they would as public shareholders of a United States company.

Fathom will be a holding company and its only material asset after completion of the Business Combination will be its interest in Fathom OpCo, and it is accordingly dependent upon distributions made by Fathom OpCo to pay dividends, taxes, and other expenses, including payments under the Tax Receivable Agreement.

Upon completion of the Business Combination, Fathom will be a holding company with no material assets other than its New Fathom Units. As a result, Fathom will have no independent means of generating revenue or cash flow. Fathom’s ability to pay dividends, taxes, and other expenses, including payments under the Tax Receivable Agreement, will depend on the financial results and cash flows of Fathom OpCo and its subsidiaries and the distributions Fathom receives from Fathom OpCo. Deterioration in the financial condition, earnings or cash flow of Fathom OpCo and its subsidiaries for any reason could limit or impair Fathom OpCo’s ability to pay such distributions. Additionally, to the extent that Fathom needs funds and Fathom OpCo and/or its subsidiaries are restricted from making such distributions under applicable law or regulation or under the terms of any financing arrangements, or Fathom OpCo and/or its subsidiaries are otherwise unable to provide such funds, it could materially adversely affect Fathom’s liquidity and financial condition.

Subject to the discussion herein, Fathom OpCo will continue to be treated as a partnership for U.S. federal income tax purposes and, as such, generally will not be subject to any entity-level U.S. federal income tax. Instead, taxable income will be allocated to holders of New Fathom Units. Accordingly, Fathom will be required to pay income taxes on its allocable share of any net taxable income of Fathom OpCo. Under the terms of the Fathom Operating Agreement, Fathom OpCo is obligated to make tax distributions to holders of the New Fathom Units (including Fathom) calculated at certain assumed tax rates. In addition to tax expenses, Fathom will also incur expenses related to its operations, including Fathom’s payment obligations under the Tax Receivable Agreement, which could be significant, and some of which will be reimbursed by Fathom OpCo (excluding payment obligations under the Tax Receivable Agreement). Fathom intends to cause Fathom OpCo to make ordinary distributions and tax distributions to holders of New Fathom Units on a pro rata basis in amounts sufficient to cover all applicable taxes, relevant operating expenses, payments by Fathom under the Tax Receivable Agreement and dividends, if any, declared by Fathom. However, as discussed above, Fathom OpCo’s ability to make such distributions may be subject to various limitations and restrictions including, but not limited

85

to, retention of amounts necessary to satisfy the obligations of Fathom OpCo and its subsidiaries and restrictions on distributions that would violate any applicable restrictions contained in Fathom OpCo’s or its subsidiaries’ debt agreements, or any applicable law, or that would have the effect of rendering Fathom OpCo or a subsidiary insolvent. To the extent that Fathom is unable to make payments under the Tax Receivable Agreement for any reason, such payments will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments under the Tax Receivable Agreement, which could be substantial.

Additionally, although Fathom OpCo and its subsidiaries generally will not be subject to any entity-level U.S. federal income tax, they may be liable for audit adjustments to prior year tax returns, absent an election to the contrary. In the event Fathom OpCo’s calculations of taxable income are incorrect, Fathom OpCo, its subsidiaries and/or their respective owners, including Fathom, in later years may be subject to material liabilities as a result of such audits.

If Fathom OpCo were treated as a corporation for U.S. federal income tax or state tax purposes, then the amount available for distribution by Fathom OpCo could be substantially reduced and the value of Fathom common stock could be adversely affected.

An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes (such as Fathom OpCo) may nonetheless be treated as, and taxable as, a corporation if it is a “publicly traded partnership” unless an exception to such treatment applies. An entity that would otherwise be classified as a partnership for U.S. federal income tax purposes will be treated as a “publicly traded partnership” if interests in such entity are traded on an established securities market or interests in such entity are readily tradable on a secondary market or the substantial equivalent thereof. If Fathom OpCo were determined to be treated as a “publicly traded partnership” (and taxable as a corporation) for U.S. federal income tax purposes, Fathom OpCo would be taxable on its income at the U.S. federal income tax rates applicable to corporations and distributions by Fathom OpCo to its partners (including Fathom) could be taxable as dividends to such partners to the extent of the earnings and profits of Fathom OpCo. In addition, Fathom would no longer have the benefit of increases in the tax basis of Fathom OpCo’s assets as a result of exchanges of New Fathom Units for shares of Fathom Class A common stock. Pursuant to the Fathom Operating Agreement, the Exchange TRA Parties (as defined in the Tax Receivable Agreement) may, from time to time, subject to the terms of the Fathom Operating Agreement, exchange their interests in Fathom OpCo and have such interests redeemed by Fathom OpCo for cash or Fathom stock. While such exchanges could be treated as trading in the interests of Fathom OpCo for purposes of testing “publicly traded partnership” status, the Fathom Operating Agreement requires Fathom to impose restrictions on exchanges that Fathom determines to be necessary or advisable so that Fathom OpCo is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. Accordingly, while such position is not free from doubt, Fathom OpCo is expected to be operated such that it is not treated as a “publicly traded partnership” taxable as a corporation for U.S. federal income tax purposes and we intend to take the position that Fathom OpCo is not so treated as a result of exchanges of its interests pursuant to the Fathom Operating Agreement.

Pursuant to the Tax Receivable Agreement, Fathom will be required to make payments to Blocker TRA Parties and Exchange TRA Parties (each as defined in the Tax Receivable Agreement) for certain tax benefits Fathom may claim and those payments may be substantial.

The Exchange TRA Parties (as defined in the Tax Receivable Agreement) will sell or exchange certain interests in Fathom OpCo pursuant to the transactions contemplated by the Business Combination Agreement and may in the future exchange their New Fathom Units, together with the cancellation of an equal number of shares of Class B common stock, for shares of Fathom Class A common stock, or cash pursuant to the Fathom Operating Agreement. Such transactions are expected to result in increases in Fathom’s allocable share of the tax basis of the tangible and intangible assets of Fathom OpCo and its subsidiaries. These increases in tax basis may increase (for income tax purposes) depreciation and amortization deductions and therefore reduce the amount of income or franchise tax that Fathom would otherwise be required to pay in the future had such sales and

86

exchanges never occurred. Additionally, in connection with the closing of the Business Combination Agreement, Fathom will acquire the Fathom Blockers from the Blocker TRA Parties (as defined in the Tax Receivable Agreement). Certain tax assets and attributes of the Fathom Blockers may be available to reduce the amount of income or franchise tax that Fathom would otherwise be required to pay in the future had it not acquired the Fathom Blockers.

In connection with the Business Combination, Fathom will enter into the Tax Receivable Agreement, which generally provides for the payment by it of 85% of the net cash savings, if any, in U.S. federal, state and local, income and franchise tax (computed using certain assumptions to address the impact of state and local taxes) that it actually realizes (or in certain cases is deemed to realize) as a result of tax basis in certain assets and other tax attributes of the Fathom Blockers and of Fathom at the time of the Business Combination (including as a result of any cash payments made to FathomOpCo in exchange for New Fathom Units pursuant to the Business Combination), any increases in tax basis and other tax benefits related to the payment of cash consideration pursuant to the Business Combination Agreement and any increases in tax basis and other tax benefits resulting from any exchange of New Fathom Units for shares of Class A common stock or cash in the future and tax benefits related to entering into and making payments under the Tax Receivable Agreement. Fathom will retain the benefit of the remaining 15% of such tax savings.

Payments under the Tax Receivable Agreement are the obligation of Fathom and not of Fathom OpCo. The actual increase in Fathom’s allocable share of Fathom OpCo’s tax basis in its assets, as well as estimating the amount and timing of any payments due to the TRA Parties based on future exchanges under the Tax Receivable Agreement, is by its nature, imprecise. For purposes of the Tax Receivable Agreement, savings in tax generally are calculated by comparing Fathom’s actual tax liability (determined by using the actual applicable U.S. federal income tax rate and assumed combined state and local income tax rate) to the amount that Fathom would have been required to pay had it not been able to utilize any of the tax benefits subject to the Tax Receivable Agreement. The amounts payable, as well as the timing of any payments under the Tax Receivable Agreement will vary depending upon a number of factors, including the timing of exchanges, the market price of the Class A common stock at the time of the exchange, the extent to which such exchanges are taxable, the depreciation and amortization periods that will apply to any increases in tax basis, the U.S. federal income tax rate then applicable, and the amount and timing of the recognition of Fathom’s income. While many of the factors that will determine the amount of payments that Fathom will make under the Tax Receivable Agreement are outside of its control, Fathom expects that the payments it will make under the Tax Receivable Agreement will be substantial. At this time, Fathom is not able to provide a meaningful range of the total amount of payments to be made under the Tax Receivable Agreement resulting from future exchanges of New Fathom Units for shares of Class A common stock with any specificity or reliability for the reasons discussed above. However, Fathom estimates that the total amount of payments anticipated to be made in the future as a result of the tax basis of Fathom at the time of the Business Combination will be $93.8 million assuming there is no redemption of outstanding Public Shares in connection with the Business Combination and $13.1 million assuming there is a maximum redemption of outstanding Public Shares in connection with the Business Combination. The amount of these payments is based upon the assumptions that (i) Fathom’s share price at the Business Combination will be equal to $10 per share, (ii) there are no changes in future income tax rates or tax laws, (iii) Fathom is able to fully utilize tax attributes arising in connection with the Business Combination in future tax periods, and (iv) there is no acceleration of amounts due under the Tax Receivable Agreement on account of early termination. The fair value of the liability associated with these payments is recognized in the “Pro Forma Condensed Combined Balance Sheet as of September 30, 2021.”

Any payments made by Fathom under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to Fathom. To the extent that Fathom is unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid; however, nonpayment for a specified period may constitute a breach of a material obligation under the Tax Receivable Agreement and therefore accelerate payments due under the Tax Receivable Agreement, as further described below. Furthermore, Fathom’s future obligation to make payments

87

under the Tax Receivable Agreement could make Fathom a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that may be realized or deemed realized under the Tax Receivable Agreement. See the section entitled “The Business Combination Agreement — Related Agreements — Tax Receivable Agreement.”

In certain cases, payments under the Tax Receivable Agreement may exceed the actual tax benefits Fathom realizes or be accelerated.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that Fathom determines under the procedures and assumptions set forth in the Tax Receivable Agreement, and the IRS or another taxing authority may challenge all or any part of the tax basis increases, as well as other tax positions that Fathom takes, and a court may sustain such a challenge. In the event that any tax benefits initially claimed by Fathom are disallowed, the Exchange TRA Parties and the Blocker TRA Parties (each as defined in the Tax Receivable Agreement) will not be required to reimburse Fathom for any excess payments that may previously have been made under the Tax Receivable Agreement, for example, due to adjustments resulting from examinations by taxing authorities. Rather, excess payments made to such holders will be netted against any future cash payments otherwise required to be made by Fathom under the Tax Receivable Agreement, if any, after the determination of such excess. However, a challenge to any tax benefits initially claimed by Fathom may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments that Fathom might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments against which to net. Actual tax benefits realized by Fathom may differ from tax benefits calculated under the Tax Receivable Agreement as a result of the use of certain assumptions in the Tax Receivable Agreement, including the use of an assumed weighted-average state and local income tax rate to calculate tax benefits. As a result, in certain circumstances Fathom could make payments under the Tax Receivable Agreement in excess of Fathom’s actual income or franchise tax savings, which could materially impair Fathom’s financial condition.

Moreover, the Tax Receivable Agreement provides that, in certain events, including a change of control, breach of a material obligation under the Tax Receivable Agreement, or Fathom’s exercise of early termination rights, Fathom’s obligations under the Tax Receivable Agreement will accelerate and Fathom will be required to make a lump-sum cash payment to the Exchange TRA Parties and the Blocker TRA Parties (each as defined in the Tax Receivable Agreement) and other applicable parties to the Tax Receivable Agreement equal to the present value of all forecasted future payments that would have otherwise been made under the Tax Receivable Agreement, which lump-sum payment would be based on certain assumptions, including those relating to Fathom’s future taxable income. The lump-sum payment could be substantial and could exceed the actual tax benefits that Fathom realizes subsequent to such payment because such payment would be calculated assuming, among other things, that Fathom would have certain tax benefits available to it and that Fathom would be able to use the potential tax benefits in future years. Assuming no material changes in the relevant tax law, we expect that if we experienced a change of control or the Tax Receivable Agreement were terminated immediately after the Business Combination, the estimated lump-sum payment would be approximately $266.3 million (calculated using a discount rate equal to a per annum rate of LIBOR plus 100 basis points, applied against an undiscounted liability of approximately $300.5 million).

There may be a material negative effect on Fathom’s liquidity if the payments required to be made by Fathom under the Tax Receivable Agreement exceed the actual income or franchise tax savings that Fathom realizes. Furthermore, Fathom’s obligations to make payments under the Tax Receivable Agreement could also have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control.

88

Fathom OpCo may directly or indirectly make distributions of cash to us substantially in excess of the amounts we use to make distributions to our stockholders and pay our expenses (including our taxes and payments by Fathom under the Tax Receivable Agreement). To the extent we do not distribute such excess cash as dividends to our shareholders, the direct or indirect holders of New Fathom Units would benefit from any value attributable to such cash as a result of their ownership of our stock upon an exchange of their New Fathom Units.

Following the Business Combination, we will receive a pro rata portion of any distributions made by Fathom OpCo. Any cash received from such distributions will first be used to satisfy any tax liability and then to make any payments required to be made by Fathom under the Tax Receivable Agreement. Subject to having available cash and subject to limitations imposed by applicable law and contractual restrictions, the Fathom Operating Agreement requires Fathom OpCo to make certain distributions to holders of New Fathom Units (including Fathom) pro rata to facilitate the payment of taxes with respect to the income of Fathom OpCo that is allocated to them. To the extent that the tax distributions we directly or indirectly receive exceed the amounts we actually require to pay taxes, Tax Receivable Agreement payments and other expenses (which is likely to be the case given that the assumed tax rate for such distributions will generally exceed our effective tax rate), we will not be required to distribute such excess cash. Our board of directors may, in its sole discretion, choose to use such excess cash for certain purposes, including to make distributions to the holders of our stock. Unless and until our board of directors chooses, in its sole discretion, to declare a distribution, we will have no obligation to distribute such cash (or other available cash other than any declared dividend) to our stockholders.

No adjustments to the exchange ratio of New Fathom Units for shares of our common stock will be made as a result of either (i) any cash distribution by us or (ii) any cash that we retain and do not distribute to our stockholders. To the extent we do not distribute such cash as dividends and instead, for example, hold such cash balances or use such cash for certain other purposes, this may result in shares of our stock increasing in value relative to the New Fathom Units. The holders of New Fathom Units may benefit from any value attributable to such cash balances if they acquire shares of our stock in an exchange of New Fathom Units.

The Domestication may result in adverse tax consequences for holders of Altimar II ordinary shares and warrants, including Public Shareholders exercising Redemption Rights.

U.S. holders (as defined in “Material U.S. Federal Income Tax Considerations — U.S. Holders” below) may be subject to U.S. federal income tax as a result of the Domestication. As discussed more fully under “Material U.S. Federal Income Tax Considerations” below, it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison LLP that the Domestication should qualify as a reorganization within the meaning of Section 368(a)(l)(F) of the Code. However, due to the absence of direct guidance on the application of Section 368(a)(1)(F) to a statutory conversion of a corporation holding only investment-type assets such as Altimar II, this result is not entirely clear.

Assuming the Domestication qualifies as a reorganization under Section 368(a)(1)(F) of the Code, U.S. holders of Altimar II ordinary shares will be subject to Section 367(b) of the Code, and as a result:

• a U.S. holder of Altimar II ordinary shares whose Altimar II ordinary shares have a fair market value of less than $50,000 on the date of the Domestication should not recognize any gain or loss and generally should not be required to include any part of Altimar II’s earnings in income pursuant to the Domestication;

• a U.S. holder of Altimar II ordinary shares whose Altimar II ordinary shares have a fair market value of $50,000 or more on the date of the Domestication, but who on the date of the Domestication owns (actually and constructively) less than 10% of the total combined voting power of all classes of Altimar II ordinary shares entitled to vote and less than 10% of the total value of all classes of Altimar II ordinary shares will generally recognize gain (but not loss) with respect to the Domestication, as if such U.S. holder exchanged its Altimar II ordinary shares for Fathom common stock in a taxable

89

transaction. As an alternative to recognizing gain, such U.S. holders may file an election to include in income as a dividend the “all earnings and profits amount” (as defined in Treasury Regulation Section 1.367(b)-2(d)) attributable to their Altimar II ordinary shares, provided certain other requirements are satisfied. Altimar II does not expect that Altimar II’s cumulative earnings and profits will be material at the time of Domestication; and

• a U.S. holder of Altimar II ordinary shares who on the date of the Domestication owns (actually and constructively) 10% or more of the total combined voting power of all classes of Altimar II ordinary shares entitled to vote or 10% or more of the total value of all classes of Altimar II ordinary shares will generally be required to include in income as a dividend the “all earnings and profits amount” (as defined in Treasury Regulation Section 1.367(b)-2(d)) attributable to its Altimar II ordinary shares. Any such U.S. holder that is a corporation may, under certain circumstances, effectively be exempt from taxation on a portion or all of the deemed dividend pursuant to Section 245A of the Code. Altimar II does not expect that Altimar II’s cumulative earnings and profits will be material at the time of the Domestication.

If Altimar II were to be treated as a PFIC, for U.S. federal income tax purposes, certain U.S. Holders may be subject to adverse tax consequences as a result of the Domestication. Pursuant to a start-up exception, a corporation will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if (i) no predecessor of the corporation was a PFIC; (ii) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year; and (iii) the corporation is not in fact a PFIC for either of those two years. Altimar II believes, although subject to uncertainty, that Altimar II’s 2021 taxable year may be the start-up year and that Altimar II may not be treated as a PFIC for 2021. The application of the start-up exception will depend, in part, on whether the Domestication is consummated in 2021. In addition, the application of the start-up exception to the present transaction involves the application of complicated rules with respect to which there is no clear authority. Accordingly, there can be no assurance with respect to Altimar II’s status as a PFIC for 2021. All holders are urged to consult their tax advisors concerning the application of the PFIC rules to Altimar II under such holder’s particular circumstances, including the potential to make a “qualified electing fund” election or a protective “qualified electing fund” election. For a more complete discussion of the requirements to qualify for the start-up exception and the potential application of the PFIC rules to U.S. holders as a result of the Domestication, see “Material U.S. Federal Income Tax Considerations — U.S. Holders — PFIC Considerations.”

Additionally, the Domestication may cause non-U.S. holders (as defined in “Material U.S. Federal Income Tax Considerations — Non-U.S. Holders” below) to become subject to U.S. federal withholding taxes on any dividends paid in respect of such non-U.S. holder’s Fathom common stock after the Domestication.

Furthermore, because the Domestication will occur immediately prior to the redemption of U.S. holders that exercise Redemption Rights, U.S. holders exercising Redemption Rights will be subject to the potential tax consequences of the Domestication.

The tax consequences of the Domestication are complex and will depend on a holder’s particular circumstances. All holders are strongly urged to consult their tax advisors for a full description and understanding of the tax consequences of the Domestication, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws. For a more complete discussion of the U.S. federal income tax consequences of the Domestication, see the discussion in the section entitled “Material U.S. Federal Income Tax Considerations.”

Fathom’s business and operations could be negatively affected if it becomes subject to any securities litigation or shareholder activism, which could cause Fathom to incur significant expense, hinder execution of business and growth strategy and impact its stock price.

In the past, following periods of volatility in the market price of a company’s securities, securities class action litigation has often been brought against that company. Shareholder activism, which could take many

90

forms or arise in a variety of situations, has been increasing recently. Volatility in the stock price of Fathom’s Class A common stock or other reasons may in the future cause it to become the target of securities litigation or shareholder activism. Securities litigation and shareholder activism, including potential proxy contests, could result in substantial costs and divert management’s and the board of directors’ attention and resources from Fathom’s business. Additionally, such securities litigation and shareholder activism could give rise to perceived uncertainties as to Fathom’s future, adversely affect its relationships with service providers and make it more difficult to attract and retain qualified personnel. Also, Fathom may be required to incur significant legal fees and other expenses related to any securities litigation and activist shareholder matters. Further, its stock price could be subject to significant fluctuation or otherwise be adversely affected by the events, risks and uncertainties of any securities litigation and shareholder activism.

In connection with the Business Combination, the Sponsor, the other Altimar II Founders, directors, executive officers, advisors and their affiliates may elect to purchase shares or Public Warrants from Public Shareholders, which may influence a vote on a proposed business combination and reduce the public “float” of our Class A ordinary shares.

In connection with the Business Combination, the Sponsor, the other Altimar II Founders, directors, executive officers, advisors or their affiliates may purchase shares or Public Warrants in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination, although they are under no obligation to do so. However, other than as expressly stated herein, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds in the Trust Account will be used to purchase shares or Public Warrants in such transactions.

In the event that the Sponsor, the other Altimar II Founders, directors, executive officers, advisors or their affiliates purchase shares in privately negotiated transactions from public shareholders who have already elected to exercise their Redemption Rights, such selling shareholders would be required to revoke their prior elections to redeem their shares. The purpose of any such purchases of shares would be to vote such shares in favor of the Business Combination and thereby increase the likelihood of obtaining shareholder approval of the Business Combination or to satisfy the Available Cash Amount Condition, where it appears that such requirement would otherwise not be met. The purpose of any such purchases of Public Warrants would be to reduce the number of Public Warrants outstanding or to vote such warrants on any matters submitted to the warrant holders for approval in connection with our initial business combination. Any such purchases of our securities may result in the completion of our initial business combination that may not otherwise have been possible. Any such purchases will be reported pursuant to Section 13 and Section 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements.

In addition, if such purchases are made, the public “float” of our Class A ordinary shares or Public Warrants and the number of beneficial holders of our securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of our securities on a national securities exchange.

There is no guarantee that a shareholder’s decision whether to redeem its shares for a pro rata portion of the Trust Account will put the shareholder in a better future economic position.

We can give no assurance as to the price at which a shareholder may be able to sell its Class A common stock in the future following the completion of the Business Combination or any alternative business combination. Certain events following the consummation of any initial business combination, including the Business Combination, may cause an increase in our share price, and may result in a lower value realized now than a shareholder might realize in the future had the shareholder not redeemed its shares. Similarly, if a shareholder does not redeem its shares, the shareholder will bear the risk of ownership of the Class A common stock after the consummation of the Business Combination, and there can be no assurance that a shareholder can sell its shares in the future for a greater amount than the redemption price set forth in this proxy statement/

91

prospectus. A shareholder should consult the shareholder’s own financial advisor for assistance on how this may affect his, her or its individual situation.

If a shareholder fails to receive notice of our offer to redeem our Class A ordinary shares in connection with the Business Combination, such shares may not be redeemed.

We will comply with the proxy rules when conducting redemptions in connection with the Business Combination. Despite our compliance with these rules, if a shareholder fails to receive our proxy solicitation, such shareholder may not become aware of the opportunity to redeem its shares. In addition, the proxy solicitation that we furnish to holders of our Class A ordinary shares in connection with the Business Combination describes the various procedures that must be complied with in order to validly redeem or tender Class A ordinary shares. In the event that a shareholder fails to comply with these procedures, its shares may not be redeemed.

If you or a “group” of shareholders are deemed to hold in excess of 15% of our Class A ordinary shares, you will lose the ability to redeem all such shares in excess of 15% of our Class A ordinary shares.

The Amended and Restated Memorandum and Articles of Association of Altimar II provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from seeking Redemption Rights with respect to more than an aggregate of 15% of the shares sold in the IPO without our prior consent, which we refer to as the “Excess Shares.” However, we would not be restricting our shareholders’ ability to vote all of their shares (including Excess Shares) for or against the Business Combination. Your inability to redeem the Excess Shares will reduce your influence over our ability to complete the Business Combination and you could suffer a material loss on your investment in us if you sell Excess Shares in open market transactions. Additionally, you will not receive redemption distributions with respect to the Excess Shares if we complete the Business Combination. As a result, you will continue to hold that number of shares exceeding 15% and, in order to dispose of such shares, would be required to sell your shares in open market transactions, potentially at a loss.

If third parties bring claims against us, the proceeds held in the Trust Account could be reduced and the per-share redemption amount received by shareholders may be less than $10.00 per share.

Our placing of funds in the Trust Account may not protect those funds from third party claims against us. Since the consummation of the IPO, we have sought and will continue to seek to have vendors, service providers, prospective target businesses, including the Continuing Fathom Unitholders in the Business Combination, and other entities with which we do business execute agreements with us waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of our Public Shareholders. However, in certain instances we have not been able to obtain such a waiver in agreements that we have executed. Further, under certain circumstances, parties that have executed such a waiver may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case, in order to gain advantage with respect to a claim against our assets, including the funds held in the Trust Account. In determining whether to enter into an agreement with a third party that refuses to execute a waiver of such claims to the monies held in the Trust Account, our management has and will consider whether competitive alternatives are reasonably available to us, and have historically only entered into agreements with third parties without such a waiver in situations where management believes that such third party’s engagement is in the best interests of Altimar II under the circumstances.

Upon redemption of our Class A ordinary shares, if we are unable to complete the initial business combination within the prescribed timeframe, or upon the exercise of a redemption right in connection with the initial business combination, we may be required to provide for payment of claims of creditors that were not waived that may be brought against us within the ten years following redemption. Although no such claims have

92

been brought against us or threatened to date, the per-share redemption amount received by Public Shareholders could be less than the $10.00 per Public Share initially held in the Trust Account, due to claims of such creditors to the extent they are brought in the future. Pursuant to a letter agreement, the Sponsor agreed that it will be liable to us if and to the extent any claims by a third party for services rendered or products sold to us, or a prospective target business with which we entered into a written letter of intent, confidentiality or other similar agreement or business combination agreement reduces the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, in each case less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under our indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act. However, we have not asked the Sponsor to reserve for such indemnification obligations, nor have we independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and we believe that the Sponsor’s only assets are securities of our company. Therefore, we cannot assure you that the Sponsor would be able to satisfy those obligations. None of our officers or directors will indemnify us for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Our directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to our Public Shareholders.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.00 per share and (ii) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per share due to reductions in the value of the trust assets, in each case less taxes payable, and the Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, our independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While we currently expect that our independent directors would take legal action on our behalf against the Sponsor to enforce its indemnification obligations to us, it is possible that our independent directors in exercising their business judgment and subject to their fiduciary duties may choose not to do so in any particular instance. If our independent directors choose not to enforce these indemnification obligations, the amount of funds in the Trust Account available for distribution to our Public Shareholders may be reduced below $10.00 per share.

We may not have sufficient funds to satisfy indemnification claims of our directors and executive officers.

We agreed to indemnify our officers and directors to the fullest extent permitted by law. However, our officers and directors agreed to waive any right, title, interest or claim of any kind in or to any monies in the Trust Account and to not seek recourse against the Trust Account for any reason whatsoever (except to the extent they are entitled to funds from the Trust Account due to their ownership of Public Shares).

Accordingly, any indemnification provided will be able to be satisfied by us only if (i) we have sufficient funds outside of the Trust Account or (ii) we consummate an initial business combination (which shall be the Business Combination should it occur). Our obligation to indemnify our officers and directors may discourage shareholders from bringing a lawsuit against our officers or directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against our officers and directors, even though such an action, if successful, might otherwise benefit us and our shareholders. Furthermore, a shareholder’s investment may be adversely affected to the extent we pay the costs of settlement and damage awards against our officers and directors pursuant to these indemnification provisions.

93

If, after we distribute the proceeds in the Trust Account to our Public Shareholders, we file a bankruptcy or winding-up petition or an involuntary or winding-up bankruptcy petition is filed against us that is not dismissed, a bankruptcy court may seek to recover such proceeds, and the members of our board of directors may be viewed as having breached their fiduciary duties to our creditors, thereby exposing the members of our board of directors and us to claims of punitive damages.

If, after we distribute the proceeds in the Trust Account to our Public Shareholders, we file a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against us that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or bankruptcy or insolvency laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by our shareholders. In addition, our board of directors may be viewed as having breached its fiduciary duty to our creditors and/or having acted in bad faith, thereby exposing itself and us to claims of punitive damages, by paying Public Shareholders from the Trust Account prior to addressing the claims of creditors.

If, before distributing the proceeds in the Trust Account to our Public Shareholders, we file a bankruptcy or winding-up petition or an involuntary or winding-up bankruptcy petition is filed against us that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of our shareholders and the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.

If, before distributing the proceeds in the Trust Account to our Public Shareholders, we file a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against us that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in our bankruptcy estate and subject to the claims of third parties with priority over the claims of our shareholders. To the extent any bankruptcy or insolvency claims deplete the Trust Account, the per-share amount that would otherwise be received by our shareholders in connection with our liquidation may be reduced.

You may only be able to exercise your Public Warrants on a “cashless basis” under certain circumstances, and if you do so, you will receive fewer Class A common stock from such exercise than if you were to exercise such warrants for cash.

The warrant agreement provides that in the following circumstances holders of warrants who seek to exercise their warrants will not be permitted to do for cash and will, instead, be required to do so on a cashless basis in accordance with Section 3(a)(9) of the Securities Act: (i) if the Class A common stock issuable upon exercise of the warrants are not registered under the Securities Act in accordance with the terms of the warrant agreement; (ii) if we have so elected and the Class A common stock are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of “covered securities” under Section 18(b)(1) of the Securities Act; and (iii) if we have so elected and we call the Public Warrants for redemption. If you exercise your Public Warrants on a cashless basis, you would pay the warrant exercise price by surrendering all of the warrants for that number of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of Class A common stock underlying the warrants, multiplied by the excess of the “fair market value” of our Class A common stock (as defined in the next sentence) over the exercise price of the warrants by (y) the fair market value. The “fair market value” is the average reported last sale price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable. As a result, you would receive fewer shares of Class A common stock from such exercise than if you were to exercise such warrants for cash.

The grant of registration rights to certain holders, including pursuant to the Subscription Agreements, and the future exercise of such rights may adversely affect the market price of our Class A common stock.

Upon the completion of the Business Combination, the Registration Rights Agreement will be entered into by and among Fathom Digital Manufacturing Corporation and certain other parties thereto, replacing Altimar II’s

94

existing registration rights agreement. The Registration Rights Agreement in substantially the form it will be executed in connection with the Closing is attached to this proxy statement/prospectus as Annex F. Pursuant to the Registration Rights Agreement, the Legacy Fathom Owners, Sponsor and other Altimar II Founders, and, in each case, their permitted transferees and assigns will have customary registration rights (including demand, shelf and piggy-back rights, subject to cooperation and cut-back provisions) with respect to their shares of common stock, other than the Backstop Shares. Further, pursuant to the Subscription Agreements, we agreed that we will use commercially reasonable best efforts (i) to file within 30 days after the closing of the Business Combination a registration statement with the SEC for (x) in the case of the Original PIPE Investment, a secondary offering of the PIPE Securities and (y) in the case of the Backstop Investment, a secondary offering of the Backstop Shares, (ii) to cause such registration statement to be declared effective promptly thereafter and (iii) to maintain the effectiveness of such registration statement until the earlier of (a) the date on which Sponsor and all of the independent directors cease to hold the securities covered thereby, and (b) the date all of the securities covered thereby can be sold publicly without restriction or limitation under Rule 144 under the Securities Act. In addition, the Subscription Agreements provide these holders will have certain “piggy-back” registration rights to include their securities in other registration statements filed by us. We will bear the cost of registering these securities. The registration and availability of such a significant number of securities for trading in the public market may have an adverse effect on the market price of the Class A common stock of Fathom.

We may have been a PFIC, which could result in adverse United States federal income tax consequences to U.S. investors.

Pursuant to a start-up exception, a corporation will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if (i) no predecessor of the corporation was a PFIC; (ii) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year; and (iii) the corporation is not in fact a PFIC for either of those two years. Altimar II believes, although subject to uncertainty, that Altimar II’s 2021 taxable year may be the start-up year and that Altimar II may not be treated as a PFIC for 2021. The application of the start-up exception will depend, in part, on whether the Domestication is consummated in 2021. In addition, the application of the start-up exception to the present transaction involves the application of complicated rules with respect to which there is no clear authority. Accordingly, there can be no assurance with respect to Altimar II’s status as a PFIC for 2021. If we have been a PFIC for any taxable year (or portion thereof) that is included in the holding period of a beneficial owner of Altimar II ordinary shares or warrants that is a “U.S. holder” as that term is defined in the section entitled “Material U.S. Federal Income Tax Considerations – U.S. Holders – PFIC Considerations,” such U.S. holder may be subject to certain adverse U.S. federal income tax consequences and may be subject to additional reporting requirements, including as a result of the Domestication. Our PFIC status for any taxable year will not be determinable until after the end of such taxable year. If we determine we are a PFIC for any taxable year, upon written request, Altimar II will endeavor to provide to a U.S. holder such information as the IRS may require, including a PFIC annual information statement, in order to enable the U.S. holder to make and maintain a “qualified electing fund” election, but there can be no assurance that we will timely provide such required information, and such election would be unavailable with respect to Altimar II warrants in all cases. The PFIC rules are complex and will depend on a holder’s particular circumstances. All U.S. holders are strongly urged to consult their tax advisors regarding the application and effect of the PFIC rules, including as a result of the Domestication, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws. For a more complete discussion of the potential application of the PFIC rules to U.S. holders as a result of the Domestication, “Material U.S. Federal Income Tax Considerations – U.S. Holders – PFIC Considerations.”

The provisions of the Amended and Restated Memorandum and Articles of Association that relate to the rights of holders of our Class A ordinary shares (and corresponding provisions of the agreement governing the release of funds from our Trust Account) may be amended with the approval of holders of at least two-thirds of our ordinary shares who attend and vote at a general meeting of Altimar II, which is a lower amendment threshold than that of some other blank check companies. It may be easier for us, therefore, to amend the Amended and Restated Memorandum and Articles of Association to facilitate the completion of the Business Combination that some of our shareholders may not support.

Some other blank check companies have a provision in their charter which prohibits the amendment of certain of its provisions, including those which relate to the rights of a company’s shareholders, without approval by a certain percentage of the company’s shareholders. In those companies, amendment of these provisions typically requires approval by between 90% and 100% of the company’s shareholders. The Amended and Restated Memorandum and Articles of Association provide that any of its provisions related to the rights of holders of our Class A ordinary shares (including the requirement to deposit proceeds of the IPO and the Private Placement of Warrants into the Trust Account and not release such amounts except in specified circumstances, and to provide Redemption Rights to Public Shareholders as described herein) may be amended if approved by special resolution, meaning holders of at least two-thirds of our ordinary shares who attend and vote at a general meeting of Altimar II, and corresponding provisions of the trust agreement governing the release of funds from our Trust Account may be amended if approved by holders of 65% of our ordinary shares; provided that the provisions of our Amended and Restated Memorandum and Articles of Association governing the appointment or removal of directors prior to our initial business combination may only be amended by a special resolution passed by not less than two-thirds of our ordinary shares who attend and vote at our general meeting which shall include the affirmative vote of a simple majority of our Class B ordinary shares. Altimar II’s Sponsor and its permitted transferees, if any, who collectively beneficially owned 20% of our issued and outstanding Class A ordinary shares, will participate in any vote to amend the Amended and Restated Memorandum and Articles of Association and/or trust agreement and will have the discretion to vote in any manner they choose. As a result, we may be able to amend the provisions of the Amended and Restated Memorandum and Articles of Association which govern our pre-Business Combination actions more easily than some other special purpose acquisition companies, and this may increase our ability to complete the Business Combination with which you may not agree. Our shareholders may pursue remedies against us for any breach of the Amended and Restated Memorandum and Articles of Association.

Sponsor, executive officers and directors agreed, pursuant to agreements with us, that they will not propose any amendment to the Amended and Restated Memorandum and Articles of Association to modify the substance or timing of our obligation to provide for the redemption of our Class A ordinary shares in connection with the Business Combination or to redeem 100% of our Class A ordinary shares if we do not complete the Business Combination within 24 months from the closing of the IPO or with respect to any other provision relating to the rights of holders of our Class A ordinary shares, unless we provide our Public Shareholders with the opportunity to redeem their Class A ordinary shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our income taxes, if any, divided by the number of then outstanding Class A ordinary shares. Our shareholders are not parties to, or third-party beneficiaries of, these agreements and, as a result, will not have the ability to pursue remedies against Sponsor, executive officers or directors for any breach of these agreements. As a result, in the event of a breach, our shareholders would need to pursue a shareholder derivative action, subject to applicable law.

96

We may amend the terms of the warrants in a manner that may be adverse to holders of Public Warrants with the approval by the holders of at least 50% of the then outstanding Public Warrants. As a result, the exercise price of the warrants could be increased, the exercise period could be shortened and the number of Class A ordinary shares purchasable upon exercise of a warrant could be decreased, all without approval of each warrant affected.

Our warrants were issued in registered form under a warrant agreement between Continental Stock Transfer and Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then outstanding Public Warrants approve of such amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the warrants, convert the warrants into cash, shorten the exercise period or decrease the number of Class A ordinary shares or Class A common stock, as applicable, purchasable upon exercise of a warrant.

We may redeem unexpired warrants prior to their exercise at a time that is disadvantageous to holders of warrants, thereby making such warrants worthless.

We have the ability to redeem outstanding warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided that the last sale price of our Class A ordinary shares or Class A common stock, as applicable, equals or exceeds $18.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) on each of 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which notice of such redemption is given. We will not redeem the warrants unless an effective registration statement under the Securities Act covering the Class A ordinary shares or Class A common stock, as applicable, issuable upon exercise of the warrants is effective and a current prospectus relating to those Class ordinary shares or Class A common stock, as applicable, is available throughout the 30-day redemption period, except if the warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under the Securities Act. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding warrants could force holders thereof to (i) exercise warrants and pay the exercise price therefor at a time when it may be disadvantageous for such holder to do so, (ii) sell warrants at the then-current market price when such holder might otherwise wish to hold warrants or (iii) accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely to be substantially less than the market value of such warrants. None of the Private Placement Warrants will be redeemable by us so long as they are held by their initial purchasers or their permitted transferees.

In addition, we may redeem warrants after they become exercisable for a number of Class A common stock determined based on the redemption date and the fair market value of our Class A common stock. Any such redemption may have similar consequences to a cash redemption described above. In addition, such redemption may occur at a time when the warrants are “out-of-the-money,” in which case holders thereof would lose any potential embedded value from a subsequent increase in the value of the Class A common stock had such warrants remained outstanding.

Our warrants may have an adverse effect on the market price of our Class A common stock.

We issued warrants to purchase 8,625,000 of our Class A ordinary shares as part of the units offered in the IPO and, simultaneously with the closing of the IPO, we issued in a private placement an aggregate of 9,900,000 Private Placement Warrants, each exercisable to purchase one Class A ordinary share at $11.50 per share. Upon

97

the Domestication, the warrants will entitle the holders to purchase shares of Class A common stock of Fathom. Such warrants, when exercised, will increase the number of issued and outstanding Class A common stock and reduce the value of the Class A common stock.

Compliance obligations under the Sarbanes-Oxley Act may make it more difficult for us to effectuate the Business Combination, require substantial financial and management resources, and increase the time and costs of completing an acquisition.

Section 404 of the Sarbanes-Oxley Act requires that we evaluate and report on our system of internal controls beginning with our Annual Report on Form 10-K for the year ending December 31, 2022. Only in the event we are deemed to be a large accelerated filer or an accelerated filer and no longer qualify as an emerging growth company will we be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting. Further, for as long as we remain an emerging growth company, we will not be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting. Following the Business Combination, we will be required to assure that we are in compliance with the provisions of the Sarbanes-Oxley Act regarding adequacy of our internal controls. The development of the internal control system to achieve compliance with the Sarbanes-Oxley Act may increase the time and costs necessary to complete the Business Combination as well as impose obligations on Fathom following the Business Combination.

The nominal purchase price paid by the Sponsor for its founder shares may significantly dilute the implied value of the Public Shares in the event we complete an initial business combination. In addition, the value of the Sponsor’s founder shares will be significantly greater than the amount the Sponsor paid to purchase such shares in the event we complete an initial business combination, even if the business combination causes the trading price of Fathom’s common stock to materially decline.

Sponsor invested an aggregate of $9,925,000 in us, comprised of the $25,000 purchase price for the founder shares and the $9,900,000 purchase price for the Private Placement Warrants. The amount held in our Trust Account was approximately $345,000,000 as of September 30, 2021, implying a value of $10 per Public Share.

The following table shows the Public Shareholders’ and the Altimar II Founders’ (including the Sponsor’s) investment per share and how these compare to the implied value of one share of Fathom common stock upon the completion of our initial business combination. The following table assumes that (i) our valuation is $345,000,000 (which is the approximate amount in the Trust Account as of September 30, 2021), (ii) no additional interest is earned on the funds held in the Trust Account, (iii) no Public Shares are redeemed in connection with our initial business combination and (iv) all founder shares are held by the Sponsor and independent directors upon completion of our initial business combination and not forfeited, and does not take into account other potential impacts on our valuation at the time of the initial business combination such as (a) the value of our Public Warrants and Private Placement Warrants, (b) the trading price of our common stock, (c) the initial business combination transaction costs (including payment of $12,075,000 of deferred underwriting commissions), (d) any equity issued or cash paid to the Legacy Fathom Owners, (e) any equity issued to other third party investors, or (f) Fathom’s business itself.

Public Shares held by Public Shareholders	34,500,000 shares
Founder shares held by the Sponsor and Altimar II independent directors	8,625,000 shares
Total number of ordinary shares	43,125,000 shares

Total funds in trust at the initial business combination	$	345,000,000
Public Shareholders’ investment per Public Share (1)	$	10.00
The Sponsor’s investment per founder share (2)	$	0.03
Implied value per share of Fathom common stock upon the initial business combination	$	8.00

98

(1) While the Public Shareholders’ investment is in both the Public Shares and the Public Warrants, for purposes of this table, the full investment amount is ascribed to the Public Shares only.

(2) The Sponsor’s total investment in the equity of the company, inclusive of the founder shares and the Sponsor’s $9,900,000 investment in the Private Placement Warrants, is $9,925,000. For purposes of this table, the full investment amount is ascribed to the founder shares only.

Based upon these assumptions, each share of Fathom common stock would have an implied value of $8.00 per share upon completion of our initial business combination, representing a 20% decrease from the initial implied value of $10.00 per Public Share. While the implied value of $8.00 per share upon completion of our initial business combination would represent a dilution to our Public Shareholders, this would represent a significant increase in value for the Sponsor relative to the price it paid for each founder share. At $8.00 per share, the 8,625,000 shares of Fathom common stock that Sponsor and our independent directors holding founder shares would own upon completion of our initial business combination would have an aggregate implied value of $69,000,000. As a result, even if the trading price of the Fathom Class A common stock significantly declines, the value of the founder shares held by Sponsor and independent directors will be significantly greater than the amount Sponsor paid to purchase such shares. In addition, the Sponsor could potentially recoup its entire investment, inclusive of its investment in the Private Placement Warrants, even if the trading price of the Fathom common stock after the initial business combination is lower than $8.00 per share. As a result, the Sponsor and independent directors holding founder shares are likely to earn a substantial profit on their investment in us upon disposition of shares of Fathom common stock even if the trading price of the Fathom common stock declines after we complete our initial business combination. Sponsor and independent directors holding founder shares may therefore be economically incentivized to complete an initial business combination with a riskier, weaker-performing or less-established target business, or on terms less favorable to the Public Shareholders, rather than liquidating Altimar II. This dilution would increase to the extent that Public Shareholders seek redemptions from the Trust Account for their Public Shares.

Public Shareholders who redeem their shares of Altimar II Class A Ordinary Shares may continue to hold any Public Warrants they own, which results in additional dilution to non-redeeming holders upon exercise of the Public Warrants.

Public Shareholders who redeem their shares may continue to hold any Public Warrants they owned prior to redemption, which results in additional dilution to non-redeeming holders upon exercise of such Public Warrants. Assuming (i) all redeeming Public Shareholders acquired units in the IPO and continue to hold the Public Warrants that were included in the units, and (ii) maximum redemption of the Class A ordinary shares held by the redeeming Public Shareholders, 8,625,000 Public Warrants would be retained by redeeming Public Shareholders with a value of $10,781,250, based on the market price of $1.25 of the Public Warrants as of September 30, 2021. As a result, the redeeming Public Shareholders would recoup their entire investment and continue to hold Public Warrants with an aggregate market value of $10,781,250, while non-redeeming Public Shareholders would suffer additional dilution in their percentage ownership and voting interest in Fathom upon exercise of the Public Warrants held by redeeming Public Shareholders.

THE BUSINESS COMBINATION AGREEMENT

This section describes the material provisions of the Business Combination Agreement and certain additional agreements entered into or to be entered into at Closing pursuant to the Business Combination Agreement (the “Related Agreements”) but does not purport to describe all of the terms thereof or include all of the additional agreements entered into or to be entered into pursuant to the Business Combination Agreement. The following summary is qualified in its entirety by reference to the complete text of the Business Combination Agreement and each of the Related Agreements. Shareholders and other interested parties are urged to read the Business Combination Agreement and such Related Agreements in their entirety.

Explanatory Note Regarding the Business Combination Agreement

The Business Combination Agreement and this summary are included to provide you with information regarding the terms of the Business Combination Agreement. The Business Combination Agreement contains representations and warranties by Altimar II and Fathom OpCo. The representations, warranties and covenants made in the Business Combination Agreement by Altimar II and Fathom OpCo were qualified and subject to important limitations agreed to by Altimar II and Fathom OpCo in connection with negotiating the terms of the Business Combination Agreement. In particular, in your review of the representations and warranties contained in the Business Combination Agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the Business Combination Agreement may have the right not to consummate the Business Combination if the representations and warranties of the other party were to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the Business Combination Agreement, rather than establishing or attempting to set forth matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC and some representations, warranties and covenants were qualified by the matters contained in the confidential disclosure letters that Altimar II and Fathom OpCo each delivered in connection with the Business Combination Agreement and certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this proxy statement/prospectus, may have changed since the date of the Business Combination Agreement.

For the foregoing reasons, the representations and warranties or any descriptions of those provisions should not be read alone or relied upon as presenting the actual state of facts or condition of Altimar II or Fathom OpCo, or any of their respective subsidiaries or affiliates. Instead, such provisions or descriptions should be read only in conjunction with the other information provided elsewhere in this document or incorporated by reference into this proxy statement/prospectus. Please see the section entitled “Where You Can Find More Information.” Altimar II will provide additional disclosures in its public reports to the extent it is aware of the existence of any material facts that are required to be disclosed under federal securities laws and that might otherwise contradict the terms and information contained in the Business Combination Agreement and will update such disclosure as required by federal securities laws.

Background of the Business Combination

The following chronology summarizes the key meetings and events that led to the signing of the Business Combination Agreement. This chronology does not purport to catalogue every conversation or correspondence among representatives of Altimar II, Fathom OpCo, their respective representatives or any other party.

Altimar II is a blank check company incorporated on December 7, 2020 as a Cayman Islands exempted company for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. Our sponsor, Altimar Sponsor II, LLC (the “Sponsor”), is affiliated with HPS Investment Partners, LLC (“HPS”), a global investment firm with approximately $75 billion of assets under management as of September 30, 2021. Altimar II’s strategy is to pursue companies that it believes

101

are poised to experience strong growth and possess business models that are or will be strong cash flow generators and to leverage HPS’ deal sourcing platform and the deep relationships of HPS’ experienced principals to identify such companies in four key industries: (1) technology, media and telecommunications, (2) healthcare, (3) financial services / financial technology and (4) consumer. Altimar II’s focus on these industries was driven in part by the expertise, experience and extensive contacts of its Sponsor with participants in each of those industries, including financial services, however Altimar II was not constrained to pursue opportunities in only these industries.

On February 4, 2021, Altimar II announced the pricing of its IPO.

On February 5, 2021, Altimar II’s capital stock began trading on NYSE. Prior to the consummation of the IPO, neither Altimar II, nor anyone on its behalf, had any substantive discussions, formal or otherwise, with respect to a potential business combination transaction with Altimar II.

After its IPO, Altimar II commenced an active search for prospective businesses and assets to acquire. Representatives of Altimar II and our Sponsor contacted and were contacted by a number of individuals and entities with respect to business combination opportunities. As part of this process, representatives of Altimar II considered and evaluated over 50 potential acquisition targets in a wide variety of industry sectors and entered into non-disclosure agreements with 19 such potential acquisition targets (including, on May 16, 2021, a non-disclosure agreement with Fathom OpCo).

As part of its regular evaluation of potential acquisition targets, Altimar II’s Board and management would meet on a regular basis to discuss the status of management’s discussions with potential acquisition targets. These updates would generally address the potential targets under consideration and the status of the discussions, if any, with the respective acquisition targets, and the updates continued throughout the period of time when Altimar II was evaluating various acquisition targets.

Of the 19 potential acquisition targets with respect to which Altimar II entered into non-disclosure agreements, representatives of Altimar II and the Sponsor participated in management presentations and engaged in due diligence and discussions directly with the applicable senior executives, shareholders and bankers of Fathom OpCo and four other potential acquisition targets. Altimar II submitted bids for each of the five potential acquisition targets and entered into letters of intent with two of the five potential acquisition targets (including Fathom OpCo). Altimar II did not proceed with finalizing a potential transaction with any potential acquisition targets other than Fathom OpCo due to variety of factors, including the absence of a mutually acceptable agreement on valuation and other key deal terms and decisions to pursue potential alternative transactions.

The proposed Business Combination with Fathom OpCo follows a search for a potential transaction utilizing the global network and investing and operating experience of Altimar II’s executive officers, principals of the Sponsor and its affiliates, and the members of Altimar II’s Board. The terms of the Business Combination Agreement and the Business Combination are the result of an arm’s length negotiation between representatives of Altimar II and Fathom OpCo following a competitive process to select a SPAC partner conducted by Fathom OpCo and CORE Industrial Partners (“CORE”, a private equity firm and majority owner of Fathom OpCo).

Altimar II decided to pursue an acquisition of Fathom OpCo because it determined that Fathom OpCo represented a compelling opportunity given its existing operations and financial performance, strong management team, strong growth and margin profile, and fast-growing and large market opportunity.

On May 18, 2021, a representative of Altimar II had a no-names discussion with Stifel, Nicolaus & Company, Incorporated (“Stifel”) regarding a potential opportunity for Altimar II.

Also on May 18, 2021, Stifel provided preliminary information about Fathom and a draft non-disclosure agreement (the “NDA”) to be executed by Altimar II in order that it may be granted access to additional information and to facilitate its due diligence review and participation in a competitive process.

Altimar II’s Board of Directors’ Reasons for Approval of the Business Combination

The Board, in evaluating the business transaction, consulted with Altimar II’s management, legal counsel and financial advisor. In reaching its conclusion to recommend that Altimar II’s shareholders approve the Business Combination Agreement and the transactions contemplated thereby, including the Business Combination, our Board considered and evaluated a number of factors, including, but not limited to, the factors discussed below. In light of the complexity of those factors, Altimar II’s directors considered these factors as a whole, and did not consider it practicable to, nor did it attempt to, quantify or otherwise assign relative weights to the specific factors it took into account in reaching its decision. Individual members of the Board may have given different weight to different factors. This explanation of the reasons for the Board approval of the Business Combination, and all other information presented in this section, is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Cautionary Statement Regarding Forward-Looking Statements.”

Before reaching its decision, the Board reviewed the results of the due diligence review conducted by its management, employees of Sponsor and its affiliates and their respective advisors, which included:

• numerous meetings and calls with the management team and advisors of Fathom OpCo regarding operations and forecasts;

• review of material contracts, material liabilities and other material matters;

• financial, legal, insurance, and accounting due diligence;

• consultation with Altimar II management and legal counsel and financial advisor;

• review of Fathom OpCo’s historical financial performance (including audited and unaudited financials) and management projections for the business; and

• financial and valuation analyses of the business of Fathom.

In the prospectus for the IPO, Altimar II identified certain criteria that Altimar II believed would be important in evaluating prospective target businesses, namely businesses with world class management teams and a compelling organic growth plan, coupled with a compelling business model that is materially cash generative at maturity. Altimar II indicated that its goal was to deliver public shareholders an opportunity to own a long term, durable compounding equity investment that can produce strong returns.

Based on its review of the industry data and the operational, financial and other relevant information related to the Fathom business, provided by Fathom and presented to the Board, the factors considered by Altimar II Board included, but were not limited to, the following:

• Fathom OpCo is an Attractive Business Opportunity. The Board considered the fact that the Fathom OpCo business (i) is of a sufficient size relevant to the public marketplace, (ii) has a strong existing management team, (iii) has a significant total addressable market and growth expansion opportunities, and (iv) would benefit from the consummation of the Business Combination by becoming a public company, which the Board believed would improve the ability of business to grow.

• Large and Expanding Growth Industry. Fathom is a leading on-demand manufacturing company in a $25+ billion low-to-mid volume manufacturing market, with robust long-standing operations and strong cash flow generation. Fathom expects wider adoption of Industry 4.0 technologies, which include additive manufacturing, CNC machining, injection molding, precision metal fabrication and other ancillary technologies, as the industry shifts from a focus on prototyping to adoption by mass manufacturers. In addition, Fathom OpCo expects the Industry 4.0 to benefit from the reshaping of new product development cycles as corporations continue to re-shore manufacturing activities, digitalize product development, mass customize products and search for higher value add, all at lower cost with shorter lead times.

• Growth Prospects. Fathom OpCo has an extensive product offering and has historically demonstrated customer demand across a diverse array of industries with little account concentration. In addition, customer demand for Fathom OpCo’s products and services is expected to position Fathom to realize strong growth prospects within the low-to-mid volume manufacturing market and adjacent markets.

108

• Platform Supports Further Growth Initiatives. Fathom OpCo has a highly attractive solutions platform with the potential to yield strong organic growth driven by the acceleration in on-demand manufacturing capabilities, including additive manufacturing and injection molding technologies. Fathom OpCo is positioned to capture growth across several markets through its robust portfolio growth with healthy upside to expand across a diversified revenue profile and technology offerings.

• Industry Leading Technology Platform and Proprietary Information. Fathom OpCo’s Industry 4.0 solutions are highly differentiated and supported by a broad technology portfolio of proprietary and differentiated technologies. Fathom is uniquely positioned as the only “full service” outsourced solution built to serve the manufacturing needs of enterprise-grade customers.

• Deep Relationships with a Broad and Diverse Customer Base. Fathom OpCo has a broad, diversified and growing customer base with demonstrated customer demand across a variety of industries.

• Attractive Valuation. The Board’s view, after consulting with its financial advisor and consultants, and supported by financial analysis performed by the Sponsor and its affiliates, that the Business Combination offers an attractive valuation for Altimar II’s shareholders. In reaching this conclusion, the Board considered various financial ratios of Fathom OpCo and its peer groups based on historical performance and projected financial performance.

• Experienced and Proven Management Team. Following completion of the Business Combination, the combined business will be led by a senior management team composed of the same senior management teams that have operated Fathom OpCo prior to the Business Combination and developed Fathom OpCo into the highly reputable and successful company that it is today. Fathom OpCo’s management team has a proven track record of operational excellence, financial performance and growth. In addition, Fathom OpCo’s Board will be comprised of experienced directors, including, among others, Robert Nardelli, former Chairman and CEO of Chrysler Corporation and The Home Depot.

• Continued Ownership by the Key Holders. The Board considered that Legacy Fathom Owners would own approximately 65% of the economic interests in Fathom following the Business Combination (assuming no redemptions by Altimar II Public Shareholders and the other assumptions set forth in “Unaudited Pro Forma Condensed Combined Financial Information”), reflecting their confidence in the Fathom business and the continued growth prospects of the Fathom business going forward. Additionally, Fathom’s current equityholders will receive part of their share of the consideration from the Business Combination in the form of unvested equity which will be subject to certain vesting terms and conditions.

• Due Diligence. Due diligence examinations of Fathom OpCo conducted by Altimar II and its advisors in several areas, including financial, legal, insurance, and accounting, and related discussions between Altimar II and such advisors with Fathom OpCo’s management in connection therewith.

• Terms and Conditions of the Business Combination Agreement. The terms and conditions of the Business Combination Agreement and the transactions contemplated thereby, including the Business Combination, were, in the opinion of the Board, consistent with similar transactions and the product of arm’s-length negotiations between the parties.

• Stockholder Liquidity. The obligation in the Business Combination Agreement to have Class A common stock issued as consideration listed on the NYSE, a major U.S. stock exchange, which the Board believes has the potential to offer stockholders enhanced liquidity.

• Involvement of the Original PIPE Investors. The Board considered that the agreement of the Original PIPE Investors to invest $80 million in the combined business at Closing at $10.00 per share was a validation of the valuation being ascribed to, and future prospects of, the combined business.

• Changes to Altimar II Capital Structure. Altimar II Founders agreed to enter into a Forfeiture and Support Agreement in connection with the Business Combination which provides, among other things, that Sponsor will waive any additional anti-dilution rights on behalf of Sponsor and the other Altimar II Founders. Additionally, the Altimar II Founders agreed to forfeit up to 15% of their Class A common stock pursuant to the terms of the Business Combination Agreement and the Forfeiture and Support Agreement, which they would otherwise receive at the closing of the Business Combination upon the automatic conversion of their Class B ordinary shares.

109

• Altimar II Shares Subject to Vesting. Pursuant to the Forfeiture and Support Agreement, 15% of Sponsor’s Class B ordinary shares (or, following the Domestication, shares of Class C common stock or Class A common stock, as applicable) will be unvested and restricted. Such shares will vest automatically upon (a) the VWAP of the Class A common stock equaling or exceeding $12.50 per share for any 20 trading days within a period of 30 consecutive trading days and (b) a change of control of Altimar II. If the unvested shares have not vested on or before the fifth anniversary of the Closing Date, such unvested shares will be automatically forfeited.

In the course of its deliberations, in addition to the various other risks associated with the combined business, as described in the section entitled “Risk Factors” appearing elsewhere in this proxy statement/prospectus, the Board also considered a variety of uncertainties, risks and other potentially negative reasons relevant to the business combination, including the following:

• Macroeconomic Risks. Macroeconomic uncertainty, including the potential impact of the COVID-19 pandemic, and the effects they could have on the combined company’s revenues and financial performance.

• Business Plan and Projections May Not Be Achieved. The risk that the combined business may not be able to execute on its business plan, and realize the financial performance as set forth in the financial projections, in each case, presented to management of Altimar II and that the historical returns attributable to Fathom OpCo may not be indicative of the future results of the combined business, which could materially affect its valuation.

• Potential Misalignment of Interests between Fathom and the Public Stockholders. The interests of the Fathom equityholders may not be aligned with the interests of the Class A common stock holders relating to, among other things, the nomination and appointment of directors to Fathom’s Board and the conduct of Fathom’s business.

• Growth Initiatives May Not be Achieved. The risk that Fathom’s growth initiatives may not be fully achieved or may not be achieved within the expected timeframe.

• No Third-Party Valuation. The fact that Altimar II did not obtain a third-party valuation or fairness opinion in connection with the Business Combination.

• Liquidation. The risks and costs to Altimar II if the Business Combination is not completed, including the risk of diverting management focus and resources from other businesses combination opportunities, which could result in Altimar II being unable to effect a business combination within the completion window which would require Altimar II to liquidate.

• Exclusivity. The fact that the Business Combination Agreement includes non-solicitation provision that prohibits Altimar II from soliciting other initial business combination proposals, which restricts Altimar II’s ability to consider other potential initial business combinations prior to the Closing or termination of the Business Combination Agreement. Altimar II’s Board, in certain circumstances, may change its recommendation in favor of the Business Combination, subject to the terms and conditions of the Business Combination Agreement.

• Restrictions in the Conduct of Business. The requirement that Fathom OpCo conducts its business in the ordinary course and the other restrictions on the conduct of Fathom OpCo’s business prior to the consummation of the Business Combination, which may delay or prevent Fathom OpCo from undertaking business opportunities that may arise pending the completion of the Business Combination.

• Distraction to Operations. The risk that the potential diversion of the management of the business and employee attention as a result of the Business Combination and the fact that Fathom OpCo will become a public company may adversely affect operations of the business.

• Shareholder Vote. The risk that Altimar II’s shareholders may object to and challenge the Business Combination and take action that may prevent or delay the consummation of the Business Combination, including to vote down the proposals at the special meeting, not vote in favor of any extension of Altimar II’s time frame to complete the Business Combination or redeem their shares.

110

• Closing Conditions. The fact that completion of the Business Combination is conditioned on the satisfaction of certain closing conditions that are not within Altimar II’s control.

• Altimar II Shareholders Holding a Minority Position in the Post-Combination Company. Following completion of the Business Combination, Altimar II’s Public Shareholders will own approximately 25.5% of the common stock of Fathom (assuming that no shares of Altimar II’s Class A ordinary shares are elected to be redeemed by Altimar II Public Shareholders).

• Governance and Structure of the Fathom Board. The fact that the Fathom Board will be a classified board, and will be initially comprised of ten directors, as follows: nine directors designated by CORE, and one independent director to be jointly designated by CORE and the Sponsor.

• Control of Fathom’s Board. The fact that following the Business Combination, CORE will have the right to nominate to the Board a number of designees equal to at least 50% of the total number of directors, so long as CORE beneficially owns shares of Fathom’s common stock representing at least a majority of the amount owned by CORE at the time of the consummation of the Business Combination. In addition, CORE will have other rights, preferences or privileges not available to other shareholders, including the right to appoint a non-voting observer to Altimar II’s Board for as long as CORE owns at least 5% of the shares owned by CORE at the Closing.

• Litigation. The possibility of litigation challenging the Business Combination or that an adverse judgment granting permanent injunctive relief could indefinitely enjoin consummation of the Business Combination.

• Fees and Expenses. The fees and expenses associated with completing the Business Combination.

• Redemptions. The risk that current Altimar II Public Shareholders would exercise their redemption rights, thereby depleting the amount of cash available in the Trust Account.

• NYSE Listing. The potential inability to maintain listing of Fathom’s securities on NYSE following the Business Combination.

In addition to considering the factors described above, the Altimar II Board also considered that:

• Interests of Certain Persons. Some officers and directors of Altimar II may have interests in the Business Combination as individuals that are in addition to, and that may be different from, the interests of Altimar II’s shareholders. See the section entitled “Certain Relationships and Related Party Transactions” for more information. Altimar II’s directors reviewed and considered these interests during the negotiation of the Business Combination and in evaluating and unanimously approving, as members of the Altimar II Board, the Business Combination Agreement and the transactions contemplated therein, including the Business Combination.

• Other Risks Factors. Various other risk factors associated with the business of Fathom and the combined business described in the section entitled “Risk Factors” beginning on page 53 of this proxy statement/prospectus.

After considering the foregoing, the Board concluded that the potential benefits to Altimar II and its shareholders relating to the Business Combination outweighed the potentially negative factors relating to the Business Combination. Accordingly, the Altimar II board of directors determined that the Business Combination Agreement and the transactions contemplated thereby, including the Business Combination, were advisable, fair to, and in the best interests of Altimar II and its shareholders. The Board therefore recommends that the shareholders of Altimar II vote to approve the proposals to be submitted to the shareholders of Altimar II with respect to the transactions contemplated by the Business Combination Agreement and the Business Combination, among other things.

Certain Projected Financial Information

Fathom OpCo does not, as a matter of general practice, publicly disclose long-term forecasts or internal projections of its future performance, revenues, earnings, financial condition or other results due to, among other reasons, the uncertainty of the underlying assumptions and estimates. However, the prospective financial information of Fathom OpCo for fiscal years 2021 through 2025, each ended December 31, prepared by Fathom

111

OpCo’s management team (the “Initial Projections”), was provided to the Altimar II Board in connection with the Altimar II Board’s consideration of the proposed Business Combination. Fathom OpCo’s management team prepared the Initial Projections as of July 15, 2021.

Fathom OpCo’s management team regularly assesses Fathom OpCo’s business outlook and financial forecasts based on the most accurate and current information available. Since the Initial Projections were finalized on July 15, 2021, Fathom OpCo’s management team identified factors likely to impact Fathom OpCo’s near-term outlook. These factors primarily relate to supply chain disruptions which have delayed certain orders expected in 2021. These supply chain disruptions are common across the additive and traditional manufacturing industries and are primarily the result of the ongoing COVID-19 pandemic and related COVID-19 restrictions and protocols which have adversely affected the global and domestic supply chains. The supply chain disruptions primarily impacted Fathom OpCo’s near-term outlook, and there has been no material change to Fathom OpCo’s long-term outlook reflected in the Initial Projections.

Fathom OpCo’s management team has prepared updated projections reflecting the expected impact of the supply chain disruptions on Fathom OpCo’s near-term outlook (such updated projections, the “Current Projections” and, together with the Initial Projections, the “Projections”). The Current Projections are included in this proxy statement/prospectus and the Altimar II Board has reviewed and discussed the Current Projections. The Current Projections do not take into account any circumstances or events occurring after the date on which the Current Projections were prepared, which was September 23, 2021.

Assumptions

In connection with the preparation of the Current Projections and the Initial Projections, Fathom OpCo’s management team considered various material assumptions, including, but not limited to, the following:

• Further market adoption and growth of additive manufacturing and Fathom’s ability to capture the revenue opportunity associated with such growth.

• Continued market penetration into Fathom’s existing core manufacturing technologies: additive manufacturing, CNC machining, precision sheet metal fabrication and injection molding.

• Cohort-based customer sales forecast model with projected revenue growth driven by share of wallet growth with existing customers, acquisition of new customers and cross-selling of recently acquired, complementary manufacturing technologies.

• Key customer projections assumptions include:

• Annual customer retention remains in line with historical rate of 91%;

• Sales growth with existing strategic customers is between 15% and 25% annually beginning in 2022;

• New customer sales growth is between 30% and 45% annually beginning in 2022; and

• The addition of approximately 150 new strategic customers beginning in 2022 through 2025 at an average initial annual spend of $250,000 per customer, growing to an average annual spend of $400,000 per customer over time.

• Expected cost of goods sold ranging from $85 million in 2021 to $193 million in 2025.

• Increasing gross profit margin from 48% in 2021 to 53% in 2025 driven by positive manufacturing technology sales mix, continued price optimization initiatives, technology advancements and factory efficiencies.

• Expected operating expenses increasing from $38 million in 2021 to $101 million in 2025, primarily attributable to increases in headcount, including salesforce expansion and marketing expenses.

• Projected annual capital expenditures increasing from $8 million in 2021 to $36 million in 2025, primarily towards the purchase/procurement of manufacturing equipment and technology infrastructure.

While presented with numerical specificity, the Projections are forward-looking and reflect numerous estimates and assumptions with respect to future industry performance under various industry scenarios as well as assumptions for competition, general business, economic, market and financial conditions and other future

112

events, as well as matters specific to the business of Fathom OpCo, all of which are difficult to predict and many of which are beyond Fathom OpCo’s control including, among other things, the matters described in the sections herein entitled “Cautionary Statement Regarding Forward-Looking Statements” and “Risk Factors.”

Initial Projections and Current Projections

The Initial Projections and the Current Projections are set forth below. The Initial Projections were previously included in Fathom OpCo’s Investor Presentation, which was filed with the SEC by Altimar II on July 16, 2021 as an exhibit to a Form 8-K. The Current Projections were previously included in Fathom OpCo’s Investor Presentation, which was filed with the SEC by Altimar II on September 23, 2021 as an exhibit to a Form 8-K. The footnotes to the tables below have been updated and modified to conform to the presentation in this proxy statement/prospectus. The tables set forth, on a non-GAAP basis, Fathom OpCo’s unaudited, adjusted results and future projections reviewed by the Altimar II Board for purposes of its consideration of the Business Combination:

(1) Information for 2020 and 2021E reflects various adjustments to give pro forma effect to the Prior Acquisitions and the 2021 Acquisitions as though such transactions occurred on January 1, 2020. This unaudited, adjusted financial data does not conform to SEC Regulation S-X or Public Company Accounting Oversight Board standards.

(2) Pro Forma Adjusted EBITDA is a non-GAAP measure and such measure for 2020 and 2021E is not comparable to Adjusted EBITDA presented elsewhere in this proxy statement/prospectus as it includes pro forma adjustments for acquisitions. Adjustments to EBITDA also include transaction and integration costs, non-recurring and non-cash items, compensation normalization and other accounting adjustments. Pro Forma Adjusted EBITDA presented above for 2020 and 2021E is most comparable to Pro Forma Adjusted EBITDA presented elsewhere in this proxy statement/Prospectus.

The Projections were prepared solely for internal use and not with a view toward public disclosure or toward complying with GAAP, the published guidelines of the SEC regarding projections or the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information. The Projections have not been audited. None of the independent registered public accounting firms of Fathom OpCo or Altimar II or any other independent accountants, have compiled, examined or performed any review or other procedures with respect to the Projections contained herein, nor have they expressed any opinion or any other form of assurance on such information or their achievability, and the independent accounting firms of Fathom OpCo and Altimar II assume no responsibility for, and disclaim any association with, the Projections.

The Projections included in this proxy statement/prospectus have been prepared by, and are the sole responsibility of, Fathom OpCo’s management team. The Projections were prepared in good faith by Fathom OpCo’s management team based on its reasonable best estimates and assumptions with respect to the expected future financial performance of Fathom OpCo as of the respective dates on which the Current Projections and Initial Projections were prepared and speak only as of such dates.

The Projections are included in this proxy statement/prospectus solely to provide Altimar II’s shareholders access to information made available in connection with the Altimar II Board’s consideration of the proposed Business Combination. The Projections are being provided for information purposes only and are not and should not be viewed as public guidance regarding the future performance of Fathom OpCo or Fathom. The actual future performance of Fathom OpCo or Fathom may vary materially from the forecasts contained in the Projections. Furthermore, the Projections do not take into account any circumstances or events occurring after September 23, 2021.

Fathom OpCo has not warranted the accuracy, reliability, appropriateness or completeness of the Projections to anyone, including Altimar II. None of Fathom OpCo’s management nor any of its representatives has made or makes any representations to any person regarding the ultimate performance of Fathom OpCo relative to the Projections. The Projections are not fact. The Projections are not a guarantee of actual future performance. The future financial results of Fathom OpCo may differ materially from those expressed in the Projections due to factors beyond Fathom OpCo’s ability to control or predict.

The Projections are included in this proxy statement/prospectus solely for informational purposes and not to induce any Altimar II shareholders to vote in favor of any of the proposals at the Special Meeting.

Altimar II and Fathom OpCo encourage you to review the financial statements of Fathom OpCo included in this proxy statement/ prospectus, as well as the financial information in the sections entitled “Fathom OpCo’s

114

Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Financial Information” and “Unaudited Pro Forma Condensed Combined Financial Information” in this proxy statement/prospectus and to not rely on any single financial measure.

None of Altimar II, Fathom OpCo or any of their respective affiliates intends to, and, except to the extent required by applicable law, each of them expressly disclaims any obligation to, update, revise or correct the Projections to reflect circumstances existing or arising after the date such Projections were generated or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying the Projections are shown to be in error or any of the Projections otherwise would not be realized.

The Projections include certain non-GAAP financial measures that are not prepared in accordance with GAAP and that may be different from non-GAAP financial measures used by other companies. Each of Fathom OpCo and Altimar II believes that the use of these non-GAAP financial measures provides an additional tool for investors and potential investors to use in evaluating Fathom OpCo’s ongoing operating results and trends. These non-GAAP measures should not be considered in isolation from, or as an alternative to, financial measures determined in accordance with GAAP. To the extent that forward-looking non-GAAP financial measures are provided, they are presented on a non-GAAP basis without reconciliations of such forward-looking non-GAAP measures to the most comparable GAAP measures due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation.

Transaction Structure

(a) Altimar II will change its jurisdiction of incorporation by deregistering as an exempted company in the Cayman Islands and continuing and domesticating as a corporation under the laws of the State of Delaware (the “Domestication”), upon which Altimar II will change its name to “Fathom Digital Manufacturing Corporation.”

(b) Fathom OpCo will issue managing member interests in Fathom OpCo to Altimar II in exchange for a nominal cash payment;

(c) Following step (b) above, each of CORE Fund I Blocker-5 LLC, a Delaware limited liability company (“Fathom Blocker 1”), CORE Fund I Blocker-2 LLC, a Delaware limited liability company (“Fathom Blocker 2”), and SG (MCT) Blocker, LLC, a Delaware limited liability company (Fathom Blocker 3” and, together with Fathom Blocker 1 and Fathom Blocker 2, the “Fathom Blockers”), will merge with and into Rapid Blocker 1 Merger Sub, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 1”), Rapid Blocker 2 Merger Sub, LLC , a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 2”), and Rapid Blocker 3 Merger Sub, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 3” and, together with Blocker Merger Sub 1 and Blocker Merger Sub 2, the “Blocker Merger Subs”), respectively, in each case, with the Fathom Blockers surviving as the surviving companies and wholly owned subsidiaries of Altimar II (collectively, the “Surviving Fathom Blockers”);

(d) Immediately following step (c) above, the Surviving Fathom Blockers will each merge with and into Altimar II (the “Blocker Altimar Mergers”), in each case, with Altimar II as the surviving company; and

(e) Immediately following the Blocker Altimar Mergers, Rapid Merger Sub will merge with and into Fathom OpCo (the “Fathom Merger”), with Fathom OpCo as the surviving entity of the Fathom Merger (Fathom OpCo, in its capacity as the surviving entity of the Fathom Merger, is sometimes referred to as the “Fathom Surviving Entity”). Following the Fathom Merger, the Fathom Surviving Entity will be owned by Altimar II and all other holders of Fathom OpCo units outstanding as of immediately prior to the Fathom Merger (such other holders, excluding Altimar II are referred to as the “Continuing Fathom Unitholders”).

Upon consummation of the transactions contemplated by the Business Combination Agreement, the combined company will be organized in an “Up-C” structure, in which substantially all of the assets and business of the

115

combined company will be held by Fathom OpCo. Altimar II and the Continuing Fathom Unitholders will be issued Class A units of Fathom OpCo (“New Fathom Units”). Altimar II will be the managing member of Fathom OpCo. Altimar II will issue to Continuing Fathom Unitholders for cash at par value a number of shares of Class B common stock equal to the number of New Fathom Units held by the Continuing Fathom Unitholders. Altimar II’s other shareholders will hold Class A common stock of the combined company. Shares of Class A common stock will be entitled to economic rights and one vote per share and shares of Class B common stock will be entitled to one vote per share but no economic rights. The combined company’s business will continue to operate through Fathom OpCo.

Post-Business Combination Ownership Structure

The diagram below depicts a simplified version of Fathom’s organizational structure and ownership immediately following the completion of the Domestication and the Business Combination (assuming (i) none of the 34,500,000 Public Shares outstanding as of the record date are redeemed by Altimar II’s Public Shareholders and (ii) no Backstop Shares are issued).

Notes:

1. Altimar II Founders include Altimar Sponsor II, LLC and the seven current directors of Altimar II.

2. The warrants held by Public Shareholders are Public Warrants and the warrants held by Altimar Sponsor II, LLC are Private Placement Warrants.

116

3. Legacy Fathom Owners include Fathom Blocker Owners and Continuing Fathom Unitholders, which include the CORE Investors.

4. The Class B common stock is non-economic, voting stock of Fathom.

5. New Fathom Units owned by the Continuing Fathom Unitholders are exchangeable on a one-for-one basis for shares of Class A common stock (with corresponding surrender of an equal number of shares of Class B common stock for cancellation by Fathom), in accordance with the Fathom Operating Agreement.

6. PIPE Investors exclude the Backstop Investors as no Backstop Shares are issued in this illustration assuming no redemptions.

Closing Funding

At the Closing, Fathom OpCo will use all amounts then available in the Trust Account (net of amounts required to redeem any Altimar Public Shareholders exercising their respective Redemption Rights) plus the proceeds of the Original PIPE Investment and Backstop Investment, if applicable, to finance the Business Combination. Fathom OpCo will use any remaining amounts to pay the transaction expenses of Altimar II, Fathom OpCo and otherwise for general corporate purposes.

Consideration to be Received in the Business Combination

The total consideration to be paid to the Fathom Blocker Owners and the Continuing Fathom Unitholders (each as defined herein), including CORE Industrial Partners Fund I, LP, at the Closing shall equal the aggregate of:

(a) (i) All the cash proceeds from the Trust Account established for the purpose of holding the net proceeds of Altimar II’s initial public offering, net of any amounts paid to Altimar II’s shareholders that exercise their redemption rights in connection with the Business Combination, together with the proceeds from the PIPE Investment (as defined herein) (the “Available Cash Amount”), (ii) minus $10,000,000 to be contributed by Altimar II to the balance sheet of Fathom OpCo (the “Balance Sheet Contribution”), (iii) minus $20,000,000 to be used to pay down certain indebtedness of Fathom OpCo, (iv) minus certain transaction expenses of Fathom OpCo and Altimar II, which include fees and expenses of various advisors, transfer taxes, employee transaction bonuses, and filing and listing fees (the “Closing Cash Consideration”); and

(b) A number of shares of Class A common stock and newly issued Class A units of Fathom OpCo (the “New Fathom Units”) (together with one share of Class B common stock to be issued at par value for cash in respect of each New Fathom Units), to be allocated as set forth on the Allocation Schedule, in an aggregate number (rounded up to the nearest whole share) equal to (a) the quotient of (i) the result of (A) $1,200,000,000 minus (B) the Closing Cash Consideration divided by (ii) $10.00 plus (b) 1,293,750, in each case of clauses (a) and (b), to be allocated as set forth on the Allocation Schedule (the “Closing Seller Equity Consideration”).

Earnout

In addition to the Closing Seller Equity Consideration, an aggregate of 9,000,000 additional shares or units of earnout equity consideration consisting of Fathom Class A common stock and New Fathom Units (collectively, the “Earnout Shares”) will be issued to the Continuing Fathom Unitholders (who will receive New Fathom Units together with shares of Altimar Class B Common Stock) and the Fathom Blocker Members (who will receive Fathom Class A common stock) pursuant to the terms of the Business Combination Agreement. The Earnout Shares will vest in three equal tranches of an aggregate amount of 3,000,000 shares of Fathom Class A common stock or New Fathom Units, as applicable, and be allocated in accordance with the Allocation Schedule, with each tranche vesting at each of the following share price thresholds: $12.50, $15.00 and $20.00, in each case subject to the

117

vesting and forfeiture provisions set forth in the Investor Rights Agreement and the Fathom Operating Agreement. The earnout period will be five years from the date of the closing of the Business Combination. The achievement of the price threshold will be determined based on the volume-weighted average share price for 20 trading days within any 30-trading day period or a change of control transaction of Fathom that implies the same per share valuation as the applicable price threshold.

Allocation Schedule

The methodology to be followed in the Allocation Schedule at the Closing will provide for the payment of the Closing Cash Consideration to direct and indirect holders of outstanding preferred units of Fathom OpCo (including accrued but unpaid preferred distributions thereon), and will allocate the balance of the Closing Cash Consideration and the total Closing Seller Equity Consideration to direct and indirect holders of outstanding common units of Fathom OpCo, on a pro rata basis in accordance with the number of outstanding common units held. The Earnout Shares will be allocated in accordance with the Allocation Schedule to the direct and indirect holders of outstanding common units of Fathom OpCo on a pro rata basis in accordance with the number of outstanding common units held. The portion of the Closing Cash Consideration to be paid to direct and indirect holders of outstanding preferred units of Fathom OpCo as described above assumes, for illustration, the inclusion of accrued preferred distributions through                  , 2021. The total amount to be paid to the holders of preferred units will vary to reflect the accrued preferred distributions as of the Closing Date.

Representations and Warranties

In General

The parties to the Business Combination Agreement have made customary representations, warranties and covenants in the Business Combination Agreement, including, among others, covenants with respect to the conduct of Altimar II, Fathom OpCo and the Fathom Blockers and their respective applicable businesses prior to the Closing. Each of Altimar II and Fathom OpCo has agreed to cooperate and use commercially reasonable efforts to cause the Business Combination to be consummated.

In addition, Fathom OpCo will have the option to elect to repay, refinance or obtain debt financing up to an aggregate amount of $175,000,000, which election will be made in consultation with Altimar II.

Sponsor also agreed to fund certain transaction expenses of Altimar II which exceed the $27,000,000 cap set forth in Section 4.03(b) of the Business Combination Agreement (other than transaction expenses in respect of (i) 50% of transfer taxes, (ii) fees and expenses of certain advisors that are, or have been, retained at the request of Fathom OpCo or (iii) printer, transfer agent and proxy solicitation fees which exceed $1,300,000, when taken together, or $27,000,000, when combined with up to $25,700,000 of the aggregate amounts of other transaction expenses of Altimar II, which excess will not be borne by Sponsor).

Material Adverse Effect

Material Adverse Effect with respect to Fathom Business

Accordingly, we expect them to vote their shares in favor of all proposals being presented at the Special Meeting.

In addition, the Altimar II Founders agreed, among other things, (i) from the date of the Business Combination Agreement until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, to not redeem any Class A ordinary shares (or, if applicable, shares of Altimar II Class A common stock) held by them and (ii) prior to the consummation of Business Combination or the termination of the Business Combination Agreement, to vote or cause to be voted, all of the Altimar II shares beneficially owned by the Altimar II Founders, at every meeting of the shareholders of Altimar II at which such matters are considered and at every adjournment or postponement thereof: (1) in favor of (A) the Business Combination and the Business Combination Agreement and the other transactions contemplated thereby (including any proposals recommended by Altimar II’s Board of Directors in connection with the Business Combination) and (B) any proposal to adjourn or postpone such meeting of shareholders to a later date if there are not sufficient votes to approve the Business Combination; (2) against any action, proposal, transaction or agreement that could reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of Altimar II under the Business Combination Agreement; and (3) against (A) any proposal or offer from any person concerning (I) a merger, consolidation, liquidation, recapitalization, share exchange or other business combination transaction involving Altimar II, or (II) the issuance or acquisition of shares of capital stock or other Altimar II equity securities (other than as contemplated or permitted by the Business Combination Agreement); and (B) any action, proposal, transaction or agreement that would reasonably be expected to (x) impede the fulfillment of Altimar II’s conditions under the Business Combination Agreement or change in any manner the voting rights of any class of Altimar II’s shares or (y) result in a breach of any covenant, representation or warranty or other obligation or agreement of Sponsor or any of the other Altimar II Founders contained in the Forfeiture and Support Agreement.

In addition, Sponsor and each of the other Altimar II Founders, in their capacity as holders of Altimar II Class B ordinary shares, have also agreed (a) not to, prior to the consummation of Business Combination or the

126

termination of the Business Combination Agreement, transfer any of the their Class B ordinary shares (or shares of Class C common stock received in the Business Combination), and in the case of Sponsor, its warrants to acquire Altimar II Class A ordinary shares, except to certain permitted transferees that agree to be bound by the terms of the Forfeiture and Support Agreement and (b) for the period beginning on the Closing Date and ending on the earlier to occur of (i) the one (1)-year anniversary of the Closing Date and (ii) the last day of the Qualifying Period (as defined below), if the VWAP of the Class A common stock equals or exceeds $12.00 per share for any twenty (20) Trading Days (as defined in the Forfeiture and Support Agreement) within a period of thirty (30) consecutive Trading Days commencing at least 150 days after the Closing Date (the “Qualifying Period”), not to transfer any of such Sponsor’s or other Altimar II Founder’s Altimar ordinary shares or Altimar common stock (other than in the case of the Sponsor, shares of Class A common stock acquired pursuant to the PIPE Investment).

Under the terms of the Forfeiture and Support Agreement, Sponsor agreed that, from and after the Closing, 1,267,500 Altimar II Class B ordinary shares (or, following the Domestication, shares of Class C common stock or Class A common stock, as applicable) held by Sponsor (other than any shares of Altimar II common stock issued to Sponsor pursuant to the PIPE Investment) (the “Sponsor Earnout Shares”) will be unvested and restricted and that such shares will vest automatically if (a) the VWAP of the Altimar II Class A common stock equals or exceeds $12.50 per share for any twenty (20) trading days within a period of thirty (30) consecutive trading days and (b) there is a change of control of Altimar II, unless the per share consideration to be received by the holders of Class A common stock in such change of control transaction is less than the vesting threshold applicable to the Sponsor Earnout Shares (each of (a) and (b), a “Vesting Event”). To the extent that, on or prior to the fifth (5th) anniversary of the Closing Date, a Vesting Event did not occur, all outstanding unvested Sponsor Earnout Shares will automatically be forfeited.

Sponsor also agreed to, at the Closing and subject to the terms and conditions of the Business Combination Agreement, provide funds to Altimar II to satisfy the funding of certain transaction expenses, after utilizing the unused portion of the working capital amount funded by Sponsor to Altimar II prior to the execution of the Business Combination Agreement, that are in excess of the aggregate $27,000,000 cap referenced in Section 4.03(b) of the Business Combination Agreement. All obligations of Altimar II to Sponsor for borrowed money or any payments made to or on behalf of Altimar II will be settled in cash and not through the issuance of warrants or other equity securities of Altimar II.

Pursuant to the Tax Receivable Agreement, Fathom will be required to pay 85% of certain tax benefits, if any, that it realizes (or in certain cases is deemed to realize) as a result of tax basis in certain assets and other tax attributes of Fathom at the time of the Business Combination, any increases in tax basis and other tax benefits related to the payment of cash consideration pursuant to the Business Combination Agreement and any increases in tax basis and other tax benefits resulting from any exchange of New Fathom Units for shares of Class A common stock or cash in the future.

127

Fathom’s obligations under the Tax Receivable Agreement accelerate upon a change in control and certain other termination events, as defined therein.

Investor Rights Agreement

Upon the completion of the Business Combination, Fathom will enter into an investor rights agreement (the “Investor Rights Agreement”) with CORE Industrial Partners Fund I, L.P., CORE Industrial Partners Fund I Parallel, L.P. (together, the “CORE Investors”), and certain equityholders of Fathom and/or Fathom OpCo named therein. The Investor Rights Agreement provides for an initial ten-person board of directors, consisting of nine individuals to be designated by the CORE Investors, which initially will include Carey Chen, TJ Chung (Chair), Caralynn Nowinski Collens, David Fisher, Maria Green, Peter Leemputte, Ryan Martin, John May and Robert Nardelli, and Adam DeWitt, our independent director mutually agreed upon by the CORE Investors and the Sponsor. The CORE Investors have certain continued nomination rights for a number of directors ranging from the majority of the board of directors to one director, while they beneficially own shares of common stock in excess of certain ownership percentages of the amount owned by the CORE Investors at Closing, as determined in accordance with the Investor Rights Agreement. In particular, from and after the Closing Date, the CORE Investors shall have the right, but not the obligation, to nominate to the Fathom board a number of designees equal to at least: (i) a majority of the board’s seats, so long as the CORE Investors beneficially own shares of common stock representing at least 50% of the total shares of Fathom common stock beneficially owned by the CORE Investors immediately after the Closing (the “Original Amount”), (ii) 35% of the board’s seats, in the event that the CORE Investors beneficially own shares of common stock representing at least 20% but less than 35% of the Original Amount, (iii) 20% of the board’s seats, in the event that the CORE Investors beneficially own shares of common stock representing at least 10% but less than 20% of the Original Amount and (iv) one director, in the event that the CORE Investors beneficially own shares of common stock representing at least 5% of the Original Amount. For purposes of calculating the number of directors that the CORE Investors are entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the nearest whole number (e.g., 11/4 directors shall equate to 2 directors) and any such calculations shall be made after taking into account any increase in the size of the board. In addition, for so long as the CORE Investors beneficially own shares of common stock representing at least 5% of the Original Amount, CORE Investors will have the right to designate a person to attend meetings of the board (including any meetings of any committees thereof) in a non-voting observer capacity.

The parties to the Investor Rights Agreement will agree (subject to exceptions for permitted transfers) to a contractual lock-up on the sale of Class A common stock for the period beginning on the Closing Date and ending one hundred eighty (180) days thereafter (the “Lock-Up Period”). The Lock-Up Period shall not apply to the Backstop Shares.

In addition, the CORE Investors and the other parties to the Investor Rights Agreement will agree to the vesting terms of the Earnout Shares. After expiration of the Lock-Up Period, the unvested Earnout Shares will not be transferable and those already vested Earnout Shares will only be transferable to those permitted transferees under the Investor Rights Agreement. In the event that any unvested Earnout Shares have not vested on or prior to the fifth (5th) anniversary of the Closing Date, those Earnout Shares that have not vested will automatically be forfeited and surrendered to Fathom for no consideration.

Registration Rights Agreement

Upon Closing, Fathom will enter into a Registration Rights Agreement. Under the terms of the Registration Rights Agreement, Fathom will grant to the Legacy Fathom Owners, including the CORE Investors, Sponsor and the other Altimar II Founders customary demand, shelf and piggyback registration rights with respect to their shares of Fathom common stock, other than the Backstop Shares. Fathom is required to file within thirty days of the Closing a shelf registration statement (“Shelf Registration Statement”) registering the public resale of the shares of common stock of Fathom held by such stockholders (“Shelf Registration Statement”), and cause the Shelf Registration Statement to be declared effective as promptly as practicable after the filing thereof and no

128

later than the earlier of (A) 60 calendar days after the filing thereof (or, in the event the SEC reviews and has written comments to the Shelf Registration Statement, the 90th calendar day following the filing thereof) and (B) the 10th business day after the date Fathom is notified (orally or in writing, whichever is earlier) by the SEC that it will not review the Shelf Registration Statement.

Fathom Operating Agreement

On the Closing Date, Fathom OpCo, Fathom and the other members named therein will enter into the Fathom Operating Agreement. The Fathom Operating Agreement will provide for a redemption right with respect to the vested New Fathom Units, pursuant to which each vested New Fathom Units will be redeemable, subject to certain limitations, for either one share of Class A common stock, or, at Fathom’s or Fathom OpCo’s election, cash of an equivalent value, pursuant to and in accordance with the terms of the Fathom Operating Agreement.

• consider and vote upon a proposal to approve by ordinary resolution, assuming the Stock Issuance Proposal and the Business Combination Issuance Proposal are approved and adopted, the ESPP, a copy of which is attached to this proxy statement/prospectus as Annex I (we refer to this proposal as the “ESPP Proposal”); and

• consider and vote upon a proposal to approve by ordinary resolution the adjournment of the Special Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the general meeting, any of the Condition Precedent Proposals would not be duly approved and adopted by our shareholders or we determine that one or more of the

132

closing conditions under the Business Combination Agreement is not satisfied or waived (we refer to this proposal as the “Adjournment Proposal”).

Recommendation of Altimar II’s Board of Directors

Altimar II’s board of directors has unanimously determined that the Business Combination Proposal is in the best interests of Altimar II and its shareholders, has unanimously approved the Business Combination Proposal, and unanimously recommends that shareholders vote “FOR” the Business Combination Proposal, “FOR” the Domestication Proposal, “FOR” the Organizational Documents Proposal, “FOR” each of the Advisory Charter Proposals, “FOR” the Stock Issuance Proposal, “FOR” the Business Combination Issuance Proposal, “FOR” the Equity Incentive Plan Proposal, “FOR” the ESPP Proposal and “FOR” the Adjournment Proposal, in each case, if presented to the Special Meeting.

The existence of financial and personal interests of Altimar II’s directors may result in a conflict of interest on the part of one or more of the directors between what he or they may believe is in the best interests of Altimar II and its shareholders and what he or they may believe is best for himself or themselves in determining to recommend that shareholders vote for the proposals. See the section entitled “The Business Combination Proposal — Interests of Altimar II Directors and Officers in the Business Combination” for a further discussion.

Record Date; Who Is Entitled to Vote

Altimar II has fixed the close of business on                 , 2021, as the “record date” for determining Altimar II shareholders entitled to notice of and to attend and vote at the Special Meeting. As of the close of business on                 , 2021, there were ordinary shares outstanding and entitled to vote. Each ordinary share is entitled to one vote per share at the general meeting.

In connection with our initial public offering, our initial shareholders (consisting of our Sponsor) and our independent directors at the time of our initial public offering entered into letter agreements to vote their founder shares, as well as any public shares purchased during or after our initial public offering, in favor of the Business Combination Proposal and we also expect them to vote their shares in favor of all other Shareholder Proposals in accordance with the terms of the Forfeiture and Support Agreement. As of the date hereof, our Sponsor owns approximately 20% of our total outstanding ordinary shares.

Quorum

The presence, in person, virtually or by proxy, of the holders of a majority of the outstanding ordinary shares entitled to vote constitutes a quorum at the general meeting.

Abstentions and Broker Non-Votes

Proxies that are marked “abstain” and proxies relating to “street name” shares that are returned to Altimar II but marked by brokers as “not voted” will be treated as shares present for purposes of determining the presence of a quorum on all matters. They will also not be treated as shares voted on the matter. If a shareholder does not give the broker voting instructions, under applicable self-regulatory organization rules, its broker may not vote its shares on “non-routine” proposals, such as the Business Combination Proposal and the Domestication Proposal.

Vote Required for Approval

The approval of the Business Combination Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting.

The approval of the Domestication Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to

133

vote at the Special Meeting, vote at the Special Meeting. The Domestication Proposal is conditioned on the approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal is not approved, the Domestication Proposal will have no effect, even if approved. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Domestication Proposal.

The approval of the Organizational Documents Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Organizational Documents Proposal is conditioned on the approval of the Domestication Proposal, and, therefore, also conditioned on approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal or the Domestication Proposal is not approved, the Organizational Documents Proposal will have no effect, Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Organizational Documents Proposal.

The approval of any of the Advisory Charter Proposals is not otherwise required by Cayman Islands law or Delaware law separate and apart from the Organizational Documents Proposal, but pursuant to SEC guidance, Altimar II is required to submit these provisions to its stockholders separately for approval. However, the stockholder votes regarding these proposals are advisory votes, and are not binding on Altimar II or the Altimar II Board (separate and apart from the approval of the Organizational Documents Proposal). Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Proposals (separate and apart from approval of the Organizational Documents Proposal).

The approval of the Stock Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the holders of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Stock Issuance Proposal is conditioned on the approval of the Organizational Documents Proposal, and, therefore, also conditioned on approval of the Domestication Proposal and the Business Combination Proposal. Therefore, if the Business Combination Proposal, the Domestication Proposal or the Organizational Documents Proposal is not approved, the Stock Issuance Proposal will have no effect, even if approved by our public shareholders.

The approval of the Business Combination Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Business Combination Issuance Proposal is conditioned on the approval of the Stock Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Equity Incentive Plan Proposal and the Organizational Documents Proposal. Therefore, if any of those proposals are not approved, the Business Combination Issuance Proposal will have no effect, even if approved by our public shareholders.

The approval of the Equity Incentive Plan Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Equity Incentive Plan Proposal is conditioned on the approval of the Business Combination Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposals and Stock Issuance Proposal. Therefore, if any of those proposals is not approved, the Equity Incentive Plan Proposal will have no effect, even if approved by Altimar II’s Public Shareholders.

The approval of the ESPP Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The ESPP Proposal is conditioned on the approval of the Business Combination Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposals and Stock Issuance Proposal.

134

Therefore, if any of those proposals is not approved, the ESPP Proposal will have no effect, even if approved by Altimar II’s Public Shareholders.

The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Adjournment Proposal is not conditioned upon any other proposal.

In each case, abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as a vote cast at the Special Meeting.

Voting Your Shares

Each ordinary share that you own in your name entitles you to one vote. Your proxy card shows the number of ordinary shares that you own. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. There are two ways to vote your ordinary shares at the Special Meeting:

• You Can Vote By Signing and Returning the Enclosed Proxy Card. If you vote by proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares will be voted as recommended by Altimar II’s board “FOR” the Business Combination Proposal, “FOR” the Domestication Proposal, “FOR” each of the separate Organizational Documents Proposal, “FOR” the Stock Issuance Proposal, “FOR” each of the Advisory Charter Proposals, “FOR” the Business Combination Issuance Proposal, “FOR” the Equity Incentive Plan Proposal, “FOR” the ESPP Proposal and “FOR” the Adjournment Proposal, in each case, if presented to the Special Meeting. Votes received after a matter has been voted upon at the Special Meeting will not be counted.

• You Can Attend the Special Meeting and Vote in Person. You will receive a ballot when you arrive. However, if your shares are held in the name of your broker, bank or another nominee, you must get a valid legal proxy from the broker, bank or other nominee. That is the only way Altimar II can be sure that the broker, bank or nominee has not already voted your shares.

Revoking Your Proxy

If you are an Altimar II shareholder and you give a proxy, you may revoke it at any time before it is exercised by doing any one of the following:

• you may send another proxy card with a later date;

• you may notify Innisfree M&A Incorporated, Altimar II’s proxy solicitor , in writing before the Special Meeting that you have revoked your proxy; or

• you may attend the Special Meeting, revoke your proxy, and vote in person or virtually, as indicated above.

Who Can Answer Your Questions About Voting Your Shares

If you are a shareholder and have any questions about how to vote or direct a vote in respect of your ordinary shares, you may call Innisfree M&A Incorporated, our proxy solicitor, by calling (877) 750-8129, or banks and brokers can call collect at (212) 750-5833.

Redemption Rights

Public Shareholders may seek to redeem the public shares that they hold, regardless of whether they vote for the Business Combination, against the Business Combination or do not vote in relation to the Business Combination. Any Public Shareholder may request redemption of their public shares for a per-share price,

135

payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest, less income taxes payable, divided by the number of then issued and outstanding public shares. If a holder properly seeks redemption as described in this section and the Business Combination is consummated, the holder will no longer own these shares following the Business Combination.

Notwithstanding the foregoing, a Public Shareholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” (as defined in Section 13(d)(3) of the Exchange Act) will be restricted from seeking redemption rights with respect to 15% or more of the shares of the public shares. Accordingly, if a Public Shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the public shares, then any such shares in excess of that 15% limit would not be redeemed for cash.

Altimar II’s initial shareholders will not have redemption rights with respect to any ordinary shares owned by them, directly or indirectly.

You will be entitled to receive cash for any public shares to be redeemed only if you:

(i) (a) hold public shares or (b) hold public shares through units and you elect to separate your units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii) prior to 5:00 p.m., Eastern Time, on                 , 2021, (a) submit a written request to the transfer agent that Altimar II redeem your public shares for cash and (b) deliver your share certificates for your public shares (if any) to the transfer agent, physically or electronically through DTC.

If you hold the shares in street name, you will have to coordinate with your broker to have your shares certificated or delivered electronically. Public shares that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $80 and it would be up to the broker whether or not to pass this cost on to the redeeming shareholder. In the event the Business Combination is not consummated this may result in an additional cost to shareholders for the return of their shares.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent, directly and instruct them to do so.

An Altimar II shareholder may not withdraw a redemption request once submitted to Altimar II unless the board of directors of Altimar II determines (in its sole discretion) to permit the withdrawal of such redemption request (which they may do in whole or in part). Furthermore, if a holder of a public share delivers its certificate (if any) and other redemption forms in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request Altimar II to permit the withdrawal of the redemption request and instruct its transfer agent to return the certificate (physically or electronically). The holder can make such request by contacting the transfer agent, at the address or email address listed in this proxy statement/prospectus.

If the Business Combination is not approved or completed for any reason, then Altimar II’s public shareholders who elected to exercise their redemption rights will not be entitled to redeem their shares. In such case, Altimar II will promptly return any shares previously delivered by public holders.

The closing price of ordinary shares on                 , 2021, the record date, was $    . Prior to exercising redemption rights, shareholders should verify the market price of ordinary shares as they may receive higher

136

proceeds from the sale of their ordinary shares in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. Altimar II cannot assure its shareholders that they will be able to sell their ordinary shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when its shareholders wish to sell their shares.

If a Public Shareholder exercises its redemption rights, then it will be exchanging its redeemed public shares for cash and will no longer own those public shares. You will be entitled to receive cash for your public shares only if you properly exercise your right to redeem the public shares that you will hold upon the Domestication, no later than the close of the vote on the Business Combination Proposal, and deliver your ordinary shares (either physically or electronically) to the transfer agent, prior to 5:00 p.m. Eastern Time on                 , 2021, and the Business Combination is consummated.

In order for Public Shareholders to exercise their redemption rights in respect of the Business Combination, Public Shareholders must properly exercise their right to redeem the public shares that you will hold upon the Domestication no later than the close of the vote on the Business Combination Proposal and deliver their ordinary shares (either physically or electronically) to the transfer agent, prior to 5:00 p.m., Eastern Time on                 , 2021. Therefore, the exercise of redemption rights occurs prior to the Domestication. For the purposes of Article 49.3 of the amended and restated memorandum and articles of association of Altimar II and Cayman Islands law, the exercise of redemption rights shall be treated as an election to have such public shares repurchased for cash and references in this proxy statement/prospectus shall be interpreted accordingly. Immediately following the Domestication and the consummation of the business combination, Public Shareholders who properly exercised their redemption rights in respect of their public shares shall be paid.

No Appraisal Rights

Neither Altimar II shareholders nor Altimar II warrant holders have appraisal rights in connection with the business combination or the Domestication under Cayman Islands law or under the DGCL.

Proxy Solicitation Costs

Altimar II is soliciting proxies on behalf of its board of directors. This solicitation is being made by mail but also may be made by telephone or in person. Altimar II and its directors, officers and employees may also solicit proxies in person, by telephone or by other electronic means. Altimar II will bear the cost of the solicitation.

Altimar II has hired Innisfree M&A Incorporated to assist in the proxy solicitation process. Altimar II will pay that firm a customary fee for its services. Such fee will be paid with non-Trust Account funds.

Altimar II will ask banks, brokers and other institutions, nominees and fiduciaries to forward the proxy materials to their principals and to obtain their authority to execute proxies and voting instructions. Altimar II will reimburse them for their reasonable expenses.

PROPOSAL NO. 1 — THE BUSINESS COMBINATION PROPOSAL

Holders of Altimar II ordinary shares are being asked to approve the Business Combination Agreement and the transactions contemplated thereby, including the Business Combination. Altimar II shareholders should read carefully this proxy statement/prospectus in its entirety for more detailed information concerning the Business Combination Agreement, substantially in the form attached as Annex C to this proxy statement/prospectus. Please see the sections entitled “The Business Combination Agreement” in this proxy statement/prospectus for additional information regarding the Business Combination and a summary of certain terms of the Business Combination Agreement. You are urged to read carefully the Business Combination Agreement in its entirety before voting on this proposal.

Altimar II may consummate the Business Combination only if it is approved by the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting.

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that Altimar II’s entry into the Business Combination Agreement, dated as of July 15, 2021 and as subsequently amended on November 16, 2021, by and among Altimar II, Fathom Holdco, LLC and the other parties thereto (in the form attached to the proxy statement/prospectus as Annex C), and the transactions contemplated by the Business Combination Agreement (the “Business Combination”) be confirmed, ratified and approved in all respects.”

Interests of Altimar II Directors and Officers in the Business Combination

In considering the recommendation of the board of directors of Altimar II to vote in favor of approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal and the other Shareholder Proposals, shareholders should keep in mind that certain members of the board of directors and officers of Altimar II and the Sponsor, including its directors and officers, have interests in such proposals that are different from, or in addition to, those of Altimar II’s shareholders generally. In particular:

• If Altimar II does not consummate a business combination by February 9, 2023 (unless such date is extended in accordance with the Amended and Restated Memorandum and Articles of Association), it would cease all operations except for the purpose of winding up, redeeming all of the outstanding Class A ordinary shares for cash and, subject to the approval of its remaining shareholders and its board of directors, dissolving and liquidating, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In such event, the 8,625,000 Class B ordinary shares would be worthless because following the redemption of the Class A ordinary shares, Altimar II would likely have few, if any, net assets and because the holders of our Class B ordinary shares have agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Class B ordinary shares if we fail to complete a Business Combination within the required period. Sponsor purchased the Class B ordinary shares prior to our initial public offering for approximately $0.003 per share. The shares of Class A common stock that the existing holders of Class B ordinary shares will hold following the Business Combination, if unrestricted and freely tradable, would have had aggregate market value of $    based upon the closing price of $    per share of public share on the NYSE on                 , the record date. Given such shares will be subject to lock-up restrictions, we believe such shares have less value.

• Sponsor purchased 9,900,000 Private Placement Warrants, each exercisable to purchase one Class A ordinary share at $11.50 per share, subject to adjustment, at a price of $1.00 per warrant, and such Private Placement Warrants will expire and be worthless if a business combination is not consummated within 24 months of the consummation of the IPO (unless such date is extended in accordance with the Existing Organizational Documents).

138

• Altimar II’s existing directors and officers will be eligible for continued indemnification and continued coverage under Altimar II’s directors’ and officers’ liability insurance after the Business Combination.

• In order to protect the amounts held in the Trust Account, Sponsor has agreed that it will be liable to Altimar II if and to the extent any claims by a vendor for services rendered or products sold to Altimar II, or a prospective target business with which Altimar II has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under our indemnity of the underwriters of Altimar II’s initial public offering against certain liabilities, including liabilities under the Securities Act.

• Following consummation of the Business Combination, Sponsor, our officers and directors and their respective affiliates would be entitled to reimbursement for certain reasonable out-of-pocket expenses related to identifying, investigating and consummating an initial business combination, and repayment of any other loans, if any, and on such terms as to be determined by Altimar II from time to time, made by Sponsor or certain of our officers and directors to finance transaction costs in connection with an intended initial business combination. However, if Altimar II fails to consummate a business combination within the required period, Sponsor and Altimar II’s officers and directors and their respective affiliates will not have any claim against the Trust Account for reimbursement.

• Under the terms of the Registration Rights Agreement, Fathom grants the Legacy Fathom Owners and Altimar II Founders certain customary demand, shelf and piggyback registration rights with respect to their shares of Fathom Class A common stock, other than the Backstop Shares.

Vote Required for Approval

The approval of this Business Combination Proposal (and consequently, the transactions contemplated by the Business Combination Agreement, including the Business Combination) requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting.

Failure to submit a proxy or to vote in person or virtually at the Special Meeting, an abstention from voting or a broker non-vote will have no effect on the Business Combination Proposal.

The Business Combination is conditioned upon the approval of the Business Combination Proposal, subject to the terms of the Business Combination Agreement. If the Business Combination Proposal is not approved, the other Shareholder Proposals (except the Adjournment Proposal, as described below) will not be presented to the shareholders for a vote.

The Sponsor and Altimar II’s directors and officers have agreed to vote the founder shares and any Class A ordinary shares owned by them in favor of the Business Combination Proposal. See “The Business Combination Agreement — Related Agreements — Forfeiture and Support Agreement” for more information.

Recommendation of the Altimar II Board of Directors

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE BUSINESS COMBINATION PROPOSAL.

139

PROPOSAL NO. 2 — THE DOMESTICATION PROPOSAL

Overview

As discussed in this proxy statement/prospectus, if the Business Combination Proposal is approved, then Altimar II is asking its shareholders to approve the Domestication Proposal. Under the Business Combination Agreement, the approval of the Domestication Proposal is also a condition to the consummation of the Business Combination. If, however, the Domestication Proposal is approved, but the Business Combination Proposal is not approved, then neither the Domestication nor the Business Combination will be consummated.

As a condition to closing the Business Combination pursuant to the terms of the Business Combination Agreement, the board of directors of Altimar II has unanimously approved a change of Altimar II’s jurisdiction of incorporation from the Cayman Islands to the State of Delaware by deregistering as an exempted company in the Cayman Islands and continuing and domesticating as a corporation incorporated under the laws of the State of Delaware (the “Domestication”). To effect the Domestication, Altimar II will file a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and file a certificate of incorporation and a certificate of corporate Domestication with the Secretary of State of the State of Delaware, under which Altimar II will be domesticated and continue as a Delaware corporation. On the effective date of the domestication, (a) each outstanding Class A ordinary share will automatically convert into one share of Class A common stock, (b) each outstanding Class B ordinary share will automatically convert into one share of Class C common stock, which shares will then automatically convert into one share of Class A common stock and (c) the outstanding warrants to purchase Class A ordinary shares will automatically become exercisable for shares of Class A common stock. In addition, at a moment in time after the effectiveness of the Domestication and before the closing of the Business Combination, each outstanding unit (each of which will consist of one share of Class A common stock and one-fourth of one warrant to purchase one share of Class A common stock) will be separated into its component common stock and warrant.

The Domestication Proposal, if approved, will approve a change of Altimar II’s jurisdiction of incorporation from the Cayman Islands to the State of Delaware. Accordingly, while Altimar II is currently governed by the Cayman Islands Companies Act, upon Domestication, Altimar II will be governed by the Delaware General Corporation Law (the “DGCL”). We urge shareholders to carefully consult the information set out below under “The Domestication Proposal — Comparison of Corporate Governance and Shareholder Rights.” Additionally, we note that if the Domestication Proposal is approved, then Altimar II will also ask its shareholders to approve the Organizational Documents Proposal (discussed below), which, if approved, will replace our current amended and restated memorandum and articles of association under the Cayman Islands law (the “Existing Organizational Documents”) with a new certificate of incorporation and bylaws of Fathom under the DGCL (the “Proposed Organizational Documents”). The Proposed Organizational Documents differ in certain material respects from the Existing Organizational Documents and we urge shareholders to carefully consult the information set out below under “The Organizational Documents Proposal,” the Existing Organizational Documents of Altimar II, attached hereto as Annex K and the Proposed Charter and Proposed Bylaws, attached hereto as Annex A and Annex B, respectively.

Reasons for the Domestication

Our board of directors believes that there are significant advantages to Altimar II that will arise as a result of a change of domicile to Delaware. Further, our board of directors believes that any direct benefit that Delaware law provides to a corporation also indirectly benefits the shareholders, who are the owners of the corporation. The board of directors believes that there are several reasons why a reincorporation in Delaware is in the best interests of Altimar II and its shareholders, including:

Prominence, Predictability, and Flexibility of Delaware Law. For many years Delaware has followed a policy of encouraging incorporation in its state and, in furtherance of that policy, has been a leader in adopting, construing, and implementing comprehensive, flexible corporate laws responsive to the legal and business needs

140

of corporations organized under its laws. Many corporations have chosen Delaware initially as a state of incorporation or have subsequently changed corporate domicile to Delaware. Because of Delaware’s prominence as the state of incorporation for many major corporations, both the legislature and courts in Delaware have demonstrated the ability and a willingness to act quickly and effectively to meet changing business needs. The DGCL is frequently revised and updated to accommodate changing legal and business needs and is more comprehensive, widely used and interpreted than other state corporate laws. This favorable corporate and regulatory environment is attractive to businesses such as ours. Based on publicly available data, over half of publicly-traded corporations in the United States and over 67% of all Fortune 500 companies are incorporated in Delaware.

Well-Established Principles of Corporate Governance. There is substantial judicial precedent in the Delaware courts as to the legal principles applicable to measures that may be taken by a corporation and to the conduct of a corporation’s board of directors, such as under the business judgment rule and other standards. Because the judicial system is based largely on legal precedents, the abundance of Delaware case law provides clarity and predictability to many areas of corporate law. Such clarity would be advantageous to Altimar II, its board of directors and management to make corporate decisions and take corporate actions with greater assurance as to the validity and consequences of those decisions and actions. Further, investors and securities professionals are generally more familiar with Delaware corporations, and the laws governing such corporations, increasing their level of comfort with Delaware corporations relative to other jurisdictions. The Delaware courts have developed considerable expertise in dealing with corporate issues, and a substantial body of case law has developed construing Delaware law and establishing public policies with respect to corporate legal affairs. Moreover, Delaware’s vast body of law on the fiduciary duties of directors provides appropriate protection for Altimar II’s shareholders from possible abuses by directors and officers.

Increased Ability to Attract and Retain Qualified Directors. Reincorporation from the Cayman Islands to Delaware is attractive to directors, officers, and shareholders alike. Altimar II’s incorporation in Delaware may make Altimar II more attractive to future candidates for our board of directors, because many such candidates are already familiar with Delaware corporate law from their past business experience. To date, we have not experienced difficulty in retaining directors or officers, but directors of public companies are exposed to significant potential liability. Thus, candidates’ familiarity and comfort with Delaware laws — especially those relating to director indemnification (as discussed below) — draw such qualified candidates to Delaware corporations. Our board of directors therefore believes that providing the benefits afforded directors by Delaware law will enable Fathom, following completion of the Business Combination, to compete more effectively with other public companies in the recruitment of talented and experienced directors and officers. Moreover, Delaware’s vast body of law on the fiduciary duties of directors provides appropriate protection for our shareholders from possible abuses by directors and officers.

The frequency of claims and litigation pursued against directors and officers has greatly expanded the risks facing directors and officers of corporations in carrying out their respective duties. The amount of time and money required to respond to such claims and to defend such litigation can be substantial. While both Cayman Islands and Delaware law permit a corporation to include a provision in its governing documents to reduce or eliminate the monetary liability of directors for breaches of fiduciary duty in certain circumstances, we believe that, in general, Delaware law is more developed and provides more guidance than Cayman Islands law on matters regarding a corporation’s ability to limit director liability. As a result, we believe that the corporate environment afforded by Delaware will enable the surviving corporation to compete more effectively with other public companies in attracting and retaining new directors.

Anticipated Accounting Treatment of the Domestication

There will be no accounting effect or change in the carrying amount of the consolidated assets and liabilities of Altimar II as a result of Domestication. The business, capitalization, assets and liabilities and financial statements of Altimar II immediately following the Domestication will be the same as those of Altimar II immediately prior to the Domestication.

141

Comparison of Corporate Governance and Shareholders

Altimar II is an exempted company incorporated under the Cayman Islands Companies Act. The Cayman Islands Companies Act and Altimar II’s Existing Organizational Documents govern the rights of its shareholders. The Cayman Islands Companies Act differs in some material respects from laws generally applicable to United States corporations and their stockholders. In addition, the Existing Organizational Documents will differ in certain material respects from the Proposed Organizational Documents. As a result, when you become a stockholder of Fathom, your rights will differ in some regards as compared to when you were a shareholder of Altimar II.

Below is a summary chart outlining important similarities and differences in the corporate governance and stockholder/shareholder rights associated with each of Altimar II and Fathom according to applicable law and/or the organizational documents of Altimar II and Fathom. You also should review the Proposed Charter and Proposed Bylaws attached hereto as Annex A and Annex B, respectively, to this proxy statement/prospectus, as well as the Delaware corporate law and corporate laws of the Cayman Islands, including the Cayman Islands Companies Act, to understand how these laws apply to Altimar II and Fathom.

	Delaware	Cayman Islands
Stockholder/Shareholder Approval of Business Combinations	Mergers generally require approval of a majority of all outstanding shares.	Mergers require a special resolution, and any other authorization as may be specified in the relevant articles of association. Parties holding certain security interests in the constituent companies must also consent.
	Mergers in which less than 20% of the acquirer’s stock is issued generally do not require acquirer stockholder approval.	All mergers (other than parent/subsidiary mergers) require shareholder approval — there is no exception for smaller mergers.
	Mergers in which one corporation owns 90% or more of a second corporation may be completed without the vote of the second corporation’s board of directors or stockholders.	Where a bidder has acquired 90% or more of the shares in a Cayman Islands company, it can compel the acquisition of the shares of the remaining shareholders and thereby become the sole shareholder. A Cayman Islands company may also be acquired through a “scheme of arrangement” sanctioned by a Cayman Islands court and approved by 50% + 1 in number and 75% in value of shareholders in attendance and voting at a general meeting.

Appraisal Rights	Generally a stockholder of a publicly traded corporation does not have appraisal rights in connection with a merger, except in certain circumstances.	Minority shareholders that dissent from a merger are entitled to be paid the fair market value of their shares, which if necessary may ultimately be determined by the court.
Inspection of Books and Records	Any stockholder may inspect the corporation’s books and records for a proper purpose during the usual hours for business.	Shareholders generally do not have any rights to inspect or obtain copies of the register of shareholders or other corporate records of a company.
Stockholder/Shareholder Lawsuits	A stockholder may bring a derivative suit subject to procedural requirements (including adopting Delaware as the exclusive forum as per Organizational Documents Proposal 3E).	In the Cayman Islands, the decision to institute proceedings on behalf of a company is generally taken by the company’s board of directors. A shareholder may be entitled to bring a derivative action on behalf of the company, but only in certain limited circumstances.
Fiduciary Duties of Directors	Directors must exercise a duty of care and duty of loyalty and good faith to the company and its stockholders.	A director owes fiduciary duties to a company, including to exercise loyalty, honesty and good faith to the company as a whole.
		In addition to fiduciary duties, directors owe a duty of care, diligence and skill. Such duties are owed to the company but may be owed direct to creditors or shareholders in certain limited circumstances

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as a special resolution, that Altimar II be de-registered in the Cayman Islands pursuant to Article 49 of the Amended and Restated Memorandum and Articles of Association of Altimar II (annexed to the prospectus/proxy statement as Annex K, the “Existing Organizational Documents”) and be registered by way of continuation as a corporation in the State of Delaware and conditional upon, and with effect from, the registration of Altimar II in the State of Delaware as a corporation with the laws of the State of Delaware, the name of Altimar Acquisition Corp. II be changed to “Fathom Digital Manufacturing Corporation” (the “Domestication” and the post-Domestication company, “Fathom”).”

Vote Required for Approval

If the Business Combination Proposal is not approved, the Domestication Proposal will not be presented at the Special Meeting. The approval of this Domestication Proposal requires a special resolution under the Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Domestication Proposal.

The Business Combination is conditioned upon the approval of the Domestication Proposal, subject to the terms of the Business Combination Agreement. Notwithstanding the approval of the Domestication Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the Domestication Proposal will not be effected.

144

PROPOSAL NO. 3 — THE ORGANIZATIONAL DOCUMENTS PROPOSAL

Overview

As discussed in this proxy statement/prospectus, if the Business Combination Proposal and the Domestication Proposal are approved, then Altimar II is asking its shareholders to approve the Organizational Documents Proposal. Under the Business Combination Agreement, the approval of the Organizational Documents Proposal is also a condition to the consummation of the Business Combination. If, however, the Organizational Documents Proposal is approved but either the Business Combination Proposal or the Domestication Proposal is not approved, then neither the Business Combination nor the Domestication will be consummated.

If each of the other Condition Precedent Proposals and the Organizational Documents Proposal are each approved and the Business Combination is to be consummated, then the Proposed Charter and the Proposed Bylaws will be substantially in the form set forth on Annex A and Annex B, respectively, and each of the matters contemplated by the Advisory Charter Proposals will be included in the Proposed Charter adopted by Fathom. The approval or lack thereof of any of the Advisory Charter Proposals will not affect the effectiveness of the Organizational Documents Proposals if approved by Altimar II’s shareholders.

All shareholders are encouraged to read the Proposed Organizational Documents in their entirety for a more complete description of their terms.

Reasons for the Organizational Documents Proposal

Each of the Proposed Charter and the Proposed Bylaws was negotiated as part of the Business Combination. The Board’s specific reasons for each of the Advisory Charter Proposals (each of which are included in the Proposed Charter) are set forth in the Section “The Advisory Charter Proposals.”

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as a special resolution, that the Existing Organizational Documents be amended and restated by their deletion and replacement in their entirety with the certificate of incorporation (the “Proposed Charter”) and bylaws of Fathom (annexed to the prospectus/proxy statement as Annex A and Annex B, respectively), which be approved and adopted as the certificate of incorporation and bylaws, respectively, of Fathom, effective upon the effectiveness of the Domestication.”

Vote Required for Approval

If the Business Combination Proposal and the Domestication Proposal are not approved, the Organizational Documents Proposal will not be presented at the Special Meeting. The approval of this Organizational Documents Proposal requires a special resolution under the Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the special meeting. Under the Amended and Restated Memorandum and Articles of Association, prior to the closing of a business combination (as defined therein) only the holders of Altimar II Class B ordinary shares will be entitled to vote on the Organizational Documents Proposal.

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE ORGANIZATIONAL DOCUMENTS PROPOSAL.

145

PROPOSAL NO. 4 — THE ADVISORY CHARTER PROPOSALS

As required by SEC guidance to give stockholders the opportunity to present their separate views on important corporate governance provisions, Altimar II is requesting that our stockholders vote upon, on a non-binding advisory basis, the Advisory Charter Proposals, which are separately being presented in accordance with SEC guidance and which will be voted upon on a non-binding advisory basis. This separate vote is not otherwise required by Delaware law or Cayman Islands law separate and apart from the Organizational Documents Proposal. However, the stockholder vote regarding each of the Advisory Charter Proposals is an advisory vote, and is not binding on the Company or our Board (separate and apart from the approval of the Organizational Documents Proposal). Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Proposals (separate and apart from approval of the Organizational Documents Proposal). Accordingly, regardless of the outcome of the non-binding advisory vote on the Advisory Charter Proposals, Altimar II intends that the Proposed Charter will take effect upon the Closing (assuming approval of the Organizational Documents Proposal).

The following table sets forth a summary of the principal changes proposed to be made between the Existing Organizational Documents and the Proposed Organizational Documents. This summary is qualified by reference to the complete text of the Proposed Organizational Documents, copies of which are attached to this proxy statement/prospectus as Annex A and Annex B, respectively.

Prior to the closing of a business combination, holders of the Class B ordinary shares have the exclusive right to remove any director and holders of Class A ordinary shares have no right to vote on the election or removal of any director. Following the closing of a business combination, directors may be removed by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock.	Our Proposed Organizational Documents provide that the election of directors shall be determined by a plurality of the votes cast by the stockholders present in person or represented by proxy at the meeting and entitled to vote thereon, voting together as a single class or, in the event that holders of any class or series of capital stock are entitled to elect one or more directors, a plurality of the votes cast by such holders. Our Proposed Charter provides that newly-created directorships or any vacancy on the board of directors may be filled solely and exclusively by a majority vote of the remaining directors then in office, even if less than a quorum, or by the sole remaining director. Our Proposed Organizational Documents provide for the removal of directors only for cause and only upon (a) prior to the first date on which CORE and its Affiliated Companies first cease to own at least 50% of the Original Amount, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of all the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class and (b) after the first date on which CORE and its Affiliated Companies cease to own at least 50% of the Original Amount, the

Voting Rights (Proposal 4F)	Our Existing Organizational Documents provide that each holder of record of Class A ordinary shares and Class B ordinary shares shall be entitled to one vote per share on all matters which shareholders are entitled to vote.	The Proposed Charter provides that each holder of record of Class A common stock, Class B common stock and Class C common stock (solely prior to the automatic conversion thereof to shares of Class A common stock as a result of the Business Combination) shall be entitled to one vote per share on all matters which stockholders generally are entitled to vote.
Dividends and Distributions (Proposal 4G)	Our Existing Organizational Documents provide that all dividends and other distributions shall be paid according to the par value of the shares held be each shareholder.	The Proposed Organizational Documents provide that subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and the Proposed Charter, the holders of shares of Class A common stock and, solely prior to the automatic conversion thereof upon and as a result of the Business Combination, holders of Class C common stock, in each case shall be entitled to receive ratably in proportion to the number of shares of Class A common stock and Class C common stock (as applicable) held by them such dividends and distributions (payable in cash, stock or

There will be no disparate consideration or treatment with respect to dividends and distributions, if any, declared or payable in respect of each share of the Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination), on the one hand, and a New Fathom Unit, on the other hand. Dividends and other distributions shall not be declared or paid on the Class B common stock unless (i) the dividend consists of shares of Class B common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B common stock paid proportionally with respect to each outstanding share of Class B common stock and (ii) a dividend consisting of shares of Class A common stock, Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A common stock (to the extent a similar or contemptuous dividend or distribution is not paid on the New Fathom Units) or Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) on equivalent terms is simultaneously paid to the holders of Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon

If dividends are declared on the Class A common stock, the Class B common stock or the Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) that are payable in shares of common stock, or securities convertible into, or exercisable or exchangeable for common stock, the dividends payable to the holders of Class A common stock shall be paid only in shares of Class A common stock (or securities convertible into, or exercisable or exchangeable for Class A common stock), the dividends payable to the holders of Class B common stock shall be paid only in shares of Class B common stock (or securities convertible into, or exercisable or exchangeable for Class B common stock), the dividends payable to the holders of Class C common stock shall be paid only in shares of Class C common stock (or securities convertible into, or exercisable or exchangeable for Class C common stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively (or securities convertible into, or exercisable or exchangeable for the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively).

Reasons for the Advisory Charter Proposals

(i) Authorized Shares (Proposal 4A)

Our Existing Organizational Documents authorized 555,000,000 shares, consisting of (a) 500,000,000 Class A ordinary shares, (b) 50,000,000 Class B ordinary shares and (c) 5,000,000 preference shares. Proposal 4A decreases the authorized number of shares to 500,000,000 shares, consisting of (a) 300,000,000 shares of Class A common stock, (b) 180,000,000 shares of Class B common stock, (c) 10,000,000 shares of Class C common stock and (d) 10,000,000 shares of preferred stock. The shares would be issuable as consideration for the Business Combination and the other transactions contemplated in this proxy statement/prospectus, and for any proper corporate purpose, including future acquisitions, capital raising transactions consisting of equity or convertible debt, stock dividends or issuances under current and any future stock incentive plans.

Our board of directors believes that this capital structure is appropriate for a newly public company such as Fathom.

(ii) Amendments to the Organizational Documents (Proposal 4B)

The Existing Organizational Documents provide that certain amendments may only be made pursuant to a special resolution under Cayman Islands law, which would require the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote on the amendment, vote on such amendment, including amendments to (i) change Altimar II’s name, (ii) alter or add to the articles of association, (iii) alter or add to the memorandum of association with respect to any objects, power or other matters specified therein, and (iv) reduce Altimar II’s share capital or any capital redemption reserve fund. The Proposed Organizational Documents allow for the Proposed Charter to be amended, altered or repealed, or any provision of the Proposed Charter inconsistent therewith may be adopted by (i) in the case of Articles 5, 6,7, 10 and 11 of the Proposed Charter, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of all the then outstanding shares of stock entitled to vote, voting together as a single class, at a meeting of the stockholders of Fathom called for that purpose and (ii) in the case of Articles 8 and 9 of the Proposed Charter, the affirmative vote of the holders of at least eighty percent (80%) of all the then outstanding shares of stock entitled to vote, voting together as a single class, at a meeting of the stockholders of Fathom called for that purpose, in each case, in addition to any other vote required by the Proposed Charter or otherwise required by law. The Board believes that the amendment approval standards contemplated by Proposal 4B are more appropriate for a public company with Fathom’s capital structure.

(iii) Director Election, Director Vacancies and Removal (Proposal 4C)

At present, our Existing Organizational Documents provide that, prior to the closing of a business combination, holders of the Class B ordinary shares have the exclusive right to elect any director and holders of Class A ordinary shares have no right to vote on the election of any director, and, following the closing of a business combination, directors may be elected by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock. Our Existing Organizational Documents also provide that newly-created directorships or any vacancy on the board of directors may be filled solely and exclusively by a majority vote of the remaining directors then in office, even if less than a quorum, or by the sole remaining

151

director. Our Existing Organizational Documents further provide that, prior to the closing of a business combination, holders of the Class B ordinary shares have the exclusive right to remove any director and holders of Class A ordinary shares have no right to vote on the removal of any director, and, following the closing of a business combination, directors may be removed by the affirmative vote of holders of a majority of the voting power of all then outstanding shares of capital stock. Proposal 4C provides that the Proposed Organizational Documents will permit for the election of directors by a plurality of the votes cast in respect of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors or, in the event that holders of any class or series of capital stock are entitled to elect one or more directors, a plurality of the votes cast by such holders. Proposal 4C also provides that newly-created directorships or any vacancy on the board of directors may be filled by a majority vote of the remaining directors then in office, even if less than a quorum or by the sole remaining director. With respect to removal of directors, Proposal 4C provides that any or all of the directors may be removed for cause and only upon (a) prior to the first date on which CORE and its affiliated companies first cease to own at least 50% of the Original Amount, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of all the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class and (b) after the first date on which CORE and its affiliated companies cease to own at least 50% of the Original Amount, the affirmative vote of the holders of at least a majority of the total voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors. The Board believes that the amendments contemplated by Proposal 4C are more appropriate for a public company, like Fathom, in which CORE, as the largest shareholder upon closing of the Business Combination, will exert substantial influence on the affairs of Fathom.

(iv) DGCL Section 203 and Business Combinations (Proposal 4D)

Under our Existing Organizational Documents, Altimar II is not governed by Section 203 of the DGCL. Proposal 4D provides that Altimar II shall not be governed by Section 203 of the DGCL. We believe that the election not to be governed by Section 203 of the DGCL provides Altimar II with increased flexibility as to future, potentially value creating, transactions.

(v) Forum Selection (Proposal 4E)

Our Existing Organizational Documents do not contain an exclusive forum provision. Proposal 4E provides that the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, another state or federal court located within the State of Delaware, shall be the exclusive forum for certain actions and claims. This amendment is intended to assist Altimar II in avoiding multiple lawsuits in multiple jurisdictions regarding the same matter. The ability to require such claims to be brought in a single forum will help to assure consistent consideration of the issues, the application of a relatively known body of case law and level of expertise, and should promote efficiency and cost-savings in the resolutions of such claims. We believe that the Delaware courts are best suited to address disputes involving such matters given that Altimar II intends to incorporate in Delaware (pending approval of the Domestication Proposal discussed above), Delaware law generally applies to such matters, and the Delaware courts have a reputation for expertise in corporate law matters. Delaware offers a specialized Court of Chancery to address corporate law matters, with streamlined procedures and processes to accelerate the timeline of legal decisions. This accelerated schedule can minimize the time, cost and uncertainty of litigation for all parties. The Court of Chancery has developed considerable expertise with respect to corporate law issues, as well as a substantial and influential body of case law construing Delaware’s corporate law and long-standing precedent regarding corporate governance. This provides shareholders and Altimar II with more predictability regarding the outcome of intra-corporate disputes. In the event the Court of Chancery does not have jurisdiction, the other state courts located in Delaware would be the most appropriate forums because these courts have more expertise on matters of Delaware law compared to other jurisdictions.

In addition, this amendment is intended to promote judicial fairness and avoid conflicting results, as well as make Altimar II’s defense of applicable claims less disruptive and more economically feasible, principally by avoiding duplicative discovery. At the same time, we believe that Altimar II should retain the ability to consent

152

to an alternative forum on a case-by-case basis where Altimar II determines that its interests and those of its shareholders are best served by permitting such a dispute to proceed in a forum other than in Delaware.

The foregoing exclusive forum provision shall not apply to any claim arising under federal securities laws, including the Securities Act as to which the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum. Notwithstanding the foregoing, the provisions of Article XI of the Proposed Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act, or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Further, Section 22 of the Securities Act of 1933 creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by that act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce this forum selection provision as written as to claims arising under the Securities Act.

(vi) Voting Rights (Proposal 4F)

Our Existing Organizational Documents provide that each holder of record of Class A ordinary shares and Class B ordinary shares shall be entitled to one vote per share on all matters which shareholders are entitled to vote. Proposal 4F provides that each holder of record of Class A common stock, Class B common stock and Class C common stock (solely prior to the automatic conversion thereof to shares of Class A common stock as a result of the Business Combination) shall be entitled to one vote per share on all matters which stockholders generally are entitled to vote. We believe that the Company’s success rests on the ability to undertake a long-term view and the voting rights set forth in the Proposed Charter will enhance the Company’s ability to focus on long-term value creation.

(vii) Dividends and Distributions (Proposal 4G)

Our Existing Organizational Documents provide that all dividends and other distributions shall be paid according to the par value of the shares held be each shareholder. Proposal 4G provides that subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and the Proposed Charter, the holders of shares of Class A common stock and, solely prior to the automatic conversion thereof upon and as a result of the Business Combination, holders of Class C common stock, in each case shall be entitled to receive ratably in proportion to the number of shares of Class A common stock and Class C common stock (as applicable) held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the Board of Directors at any time and from time to time out of any funds of Fathom legally available therefor. There will be no disparate consideration or treatment with respect to dividends and distributions, if any, declared or payable in respect of each share of the Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination), on the one hand, and a New Fathom Unit, on the other hand. Dividends and other distributions shall not be declared or paid on the Class B common stock unless (i) the dividend consists of shares of Class B common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B common stock paid proportionally with respect to each outstanding share of Class B common stock and (ii) a dividend consisting of shares of Class A common stock, Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A common stock (to the extent a similar or contemptuous dividend or distribution is not paid on the New Fathom Units) or Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) on equivalent terms is simultaneously paid to the holders of Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination). If dividends are declared on the Class A common stock, the Class B common stock or the Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) that are payable in shares of common stock, or securities convertible into, or exercisable or exchangeable for common stock, the dividends payable to the holders of Class A common stock shall be paid only in shares of Class A common stock (or securities convertible into, or exercisable or exchangeable for

153

Class A common stock), the dividends payable to the holders of Class B common stock shall be paid only in shares of Class B common stock (or securities convertible into, or exercisable or exchangeable for Class B common stock), the dividends payable to the holders of Class C common stock shall be paid only in shares of Class C common stock (or securities convertible into, or exercisable or exchangeable for Class C common stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively (or securities convertible into, or exercisable or exchangeable for the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively). We believe that the Company’s success rests on the ability to undertake a long-term view and procedures concerning our dividends and distributions will enhance the Company’s ability to focus on long-term value creation.

(viii) Removal of Blank Check Company Provisions (Proposal 4H)

Our Existing Organizational Documents contain various provisions applicable only to blank check companies. Proposal 4H eliminates certain provisions related to our status as a blank check company, including the provisions requiring that Altimar II have net tangible assets of at least $5,000,001 immediately prior to, or upon such consummation of, a business combination, which is desirable because these provisions will serve no purpose following the Business Combination. For example, these proposed amendments remove the requirement to dissolve Altimar II and allow it to continue as a corporate entity with perpetual existence following consummation of the Business Combination. Perpetual existence is the usual period of existence for corporations, and we believe it is the most appropriate period for Altimar II following the Business Combination. In addition, certain other provisions in our Existing Organizational Documents require that proceeds from Altimar II’s initial public offering be held in the Trust Account until a business combination or liquidation of merger has occurred. These provisions cease to apply once the Business Combination is consummated.

Anti-Takeover Effects of the Proposed Organizational Documents and Certain Provisions of Delaware Law

The Proposed Organizational Documents will contain, and the DGCL contains, provisions that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of our board of directors to maximize shareholder value in connection with any unsolicited offer to acquire Altimar II. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of Altimar II by means of a tender offer, a proxy contest or other takeover attempt that a shareholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of common stock held by shareholders. See “Description of Fathom’s Capital Stock — Anti-Takeover Effects of Provisions of Delaware Law and our Proposed Charter and Proposed Bylaws” for more information.

“RESOLVED, as a special resolution, on a non-binding advisory basis, that the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, another state or federal court located within the State of Delaware, shall be the exclusive forum for certain actions and claims.”

“RESOLVED, as a special resolution, on a non-binding advisory basis, that each holder of record of Class A common stock, Class B common stock and Class C common stock (solely prior to the automatic conversion thereof to shares of Class A common stock as a result of the Business Combination) shall be entitled to one vote per share on all matters which stockholders generally are entitled to vote.”

“RESOLVED, as a special resolution, on a non-binding advisory basis, that subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and the Proposed Charter, the holders of shares of Class A common stock and, solely prior to the automatic conversion thereof upon and as a result of the Business Combination, holders of Class C common stock, in each case shall be entitled to receive ratably in proportion to the number of shares of Class A common stock and Class C common stock (as applicable) held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the board of directors at any time and from time to time out of any funds of Fathom legally available therefor. There will be no disparate consideration or treatment with respect to dividends and distributions, if any, declared or payable in respect of each share of the Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon and as a result of

155

the Business Combination), on the one hand, and a New Fathom Unit (as defined in the proxy statement/prospectus), on the other hand. Dividends and other distributions shall not be declared or paid on the Class B common stock unless (i) the dividend consists of shares of Class B common stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B common stock paid proportionally with respect to each outstanding share of Class B common stock and (ii) a dividend consisting of shares of Class A common stock, Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A common stock (to the extent a similar or contemptuous dividend or distribution is not paid on the New Fathom Units) or Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) on equivalent terms is simultaneously paid to the holders of Class A common stock and Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination). If dividends are declared on the Class A common stock, the Class B common stock or the Class C common stock (solely prior to the automatic conversion thereof upon and as a result of the Business Combination) that are payable in shares of common stock, or securities convertible into, or exercisable or exchangeable for common stock, the dividends payable to the holders of Class A common stock shall be paid only in shares of Class A common stock (or securities convertible into, or exercisable or exchangeable for Class A common stock), the dividends payable to the holders of Class B common stock shall be paid only in shares of Class B common stock (or securities convertible into, or exercisable or exchangeable for Class B common stock), the dividends payable to the holders of Class C common stock shall be paid only in shares of Class C common stock (or securities convertible into, or exercisable or exchangeable for Class C common stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively (or securities convertible into, or exercisable or exchangeable for the same number of shares (or fraction thereof) on a per share basis of the Class A common stock, Class B common stock and Class C common stock, respectively).”

“RESOLVED, as a special resolution, on a non-binding advisory basis, to eliminate various provisions in the Existing Organizational Documents applicable only to blank check companies, including the provisions requiring that Altimar II have net tangible assets of at least $5,000,001 immediately prior to, or upon such consummation of, a business combination.”

Vote Required for Approval

The approval of each of the Advisory Charter Proposals, each of which is a non-binding advisory vote, requires a special resolution under the Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting. As discussed above, the Advisory Charter Proposals are advisory votes and therefore are not binding on Altimar II or our Board. Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Proposals (separate and apart from approval of the Organizational Documents Proposal). Accordingly, regardless of the outcome of the non-binding advisory vote on the Advisory Charter Proposals, Altimar II intends that the Proposed Charter will take effect upon the Closing (assuming approval of the Organizational Documents Proposal).

Recommendation of the Altimar II Board of Directors

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE ADVISORY CHARTER PROPOSALS.

156

PROPOSAL NO. 5 — THE STOCK ISSUANCE PROPOSAL

Prior to and in connection with the Business Combination, we intend to effect the issuance and sale of 8,000,000 shares of Class A common stock to the Original PIPE Investors pursuant to the Original PIPE Subscription Agreements. If necessary, we intend to effect the issuance and sale of up to 1,000,000 shares of Class A common stock to the Backstop Investors pursuant to the CORE Backstop Agreement.

Why Altimar II Needs Shareholder Approval

We are seeking shareholder approval in order to comply with Rule 312.03 of the NYSE Listed Company Manual.

Under Rule 312.03 of the NYSE Listed Company Manual, shareholder approval is required prior to the issuance of shares of common stock in certain circumstances, including (unless one or more exceptions in Rule 312.03 of NYSE Listed Company Manual apply), (a) if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance or such shares have voting power equal to or in excess of 20 percent of the voting power outstanding before the issuance or (b) if such issuance is to a Related Party (as defined in Rule 312.03 of the NYSE Listed Company Manual) and the number of shares of common stock to be issued exceeds one percent of the number of shares of common stock outstanding before the issuance. The maximum aggregate number of shares of Class A common stock issuable pursuant to the PIPE Subscription Agreements represents greater than 20% of the number of shares of Class A common stock outstanding before such issuance. Moreover, to the extent that one or more of the PIPE Investors is a Related Party of Altimar II, such issuance may require shareholder approval under Rule 312.03 of the NYSE Listed Company Manual. As a result, shareholder approval of the issuance of shares of Class A common stock issuable pursuant to the PIPE Subscription Agreements is being sought under the NYSE regulations.

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that, for the purposes of complying with the applicable New York Stock Exchange (“NYSE”) listing rules, the issuance of shares of Class A common stock of Fathom to the PIPE Investors pursuant to the PIPE Subscription Agreements (as defined in the proxy statement/prospectus) be confirmed, ratified and approved in all respects.”

Vote Required for Approval

If any of the Business Combination Proposal, the Domestication Proposal or the Organizational Documents Proposal is not approved, the Stock Issuance Proposal will not be presented at the Special Meeting. The approval of this Stock Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the majority of the of the holders of the ordinary shares who, being present (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting.

Failure to submit a proxy or to vote in person at the Special Meeting, an abstention from voting or a broker non-vote will have no effect on the Stock Issuance Proposal.

The Business Combination is conditioned upon the approval of the Stock Issuance Proposal, subject to the terms of the Business Combination Agreement. Notwithstanding the approval of the Stock Issuance Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the Stock Issuance Proposal will not be effected.

The Sponsor and the other Altimar II Founders have agreed to vote the founder shares and any Class A ordinary shares owned by them in favor of the Stock Issuance Proposal. See “The Business Combination Agreement — Related Agreements — Forfeiture and Support Agreement” for more information.

Recommendation of the Altimar II Board of Directors

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE STOCK ISSUANCE PROPOSAL.

157

PROPOSAL NO. 6 — THE BUSINESS COMBINATION ISSUANCE PROPOSAL

In connection with the Business Combination, we intend to effect the issuance of shares of Class A common stock, Class B common stock and Class C common stock (i) pursuant to the terms of the Business Combination Agreement, (ii) upon the exchange of New Fathom Units pursuant to the Fathom Operating Agreement and (iii) upon the conversion, in accordance with our Proposed Charter, of any such common stock issued pursuant to (i) or (ii).

Why Altimar II Needs Shareholder Approval

We are seeking shareholder approval in order to comply with Rule 312.03 of the NYSE Listed Company Manual.

Under Rule 312.03 of the NYSE Listed Company Manual, shareholder approval is required prior to the issuance of shares of common stock in certain circumstances, including (unless one or more exceptions in Rule 312.03 of NYSE Listed Company Manual apply), (a) if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance or such shares have voting power equal to or in excess of 20 percent of the voting power outstanding before the issuance, (b) if such issuance is to a Related Party (as defined in Rule 312.03 of the NYSE Listed Company Manual) and the number of shares of common stock to be issued exceeds one percent of the number of shares of common stock outstanding before the issuance, or (c) if such issuance will result in a change of control of the issuer. The issuance of shares of Class A common stock, Class B common stock and Class C common stock (i) pursuant to the terms of the Business Combination Agreement, (ii) upon the exchange of New Fathom Units pursuant to the Fathom Operating Agreement and (iii) upon the conversion, in accordance with our Proposed Charter, of any such common stock issued pursuant to (i) or (ii) will equal or exceed 20% of the number of shares of Company common stock outstanding before the issuance and have voting power equal to or in excess of 20 percent of the voting power of the Company’s voting securities outstanding before the issuance and such issuance may be deemed to result in a change of control of Altimar II. Furthermore, to the extent any person receiving Company common stock pursuant to the Business Combination Agreement is, at the time of issuance or in the future upon exchange of New Fathom Units or conversion of any such class of common stock, a Related Party, such issuance may require shareholder approval under Rule 312.03 of the NYSE Listed Company Manual. As a result, shareholder approval of the issuance of shares Company common stock pursuant to the Business Combination Agreement is being sought under the NYSE regulations.

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that, for the purposes of complying with the applicable listing rules of the NYSE (including any rules applicable to a “change of control”), the issuance of shares of Class A common stock, Class B common stock and Class C common stock (i) pursuant to the terms of the Business Combination Agreement, (ii) upon the exchange of New Fathom Units pursuant to the Fathom Operating Agreement (annexed to the proxy statement/prospectus as Annex G) and (iii) upon the conversion, in accordance with our Proposed Charter, of any such common stock issued pursuant to (i) or (ii), in each case, be confirmed, ratified and approved in all respects.”

Vote Required for Approval

If any of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal or the Stock Issuance Proposal is not approved, the Business Combination Issuance Proposal will not be presented at the Special Meeting. The approval of this Business Combination Issuance Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a majority of the of the holders of

158

the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting.

Recommendation of the Altimar II Board of Directors

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE BUSINESS COMBINATION ISSUANCE PROPOSAL.

159

PROPOSAL NO. 7 — THE EQUITY INCENTIVE PLAN PROPOSAL

The Board expects to approve the Fathom 2021 Omnibus Incentive Plan (the “2021 Omnibus Plan”) and adopt the 2021 Omnibus Plan, effective as of the Closing, subject to the approval of our shareholders. We are seeking shareholder approval of the 2021 Omnibus Plan (i) in order for incentive stock options to meet the requirements of the Code and (ii) in order to comply with the NYSE listing rules.

The Board believes that the approval of the 2021 Omnibus Plan by the shareholders will benefit the compensation structure and strategy of Fathom. Fathom’s ability to attract, retain and motivate top quality management, employees, partners, consultants, advisors and non-employee directors is material to its success, and the Board has concluded that this would be enhanced by the ability to make grants under the 2021 Omnibus Plan. In addition, the Board believes that the interests of Fathom and shareholders will be advanced if Fathom can offer employees and non-employee directors the opportunity to acquire or increase their proprietary interests in Fathom.

Set forth below is a summary of the material terms of the 2021 Omnibus Plan. This summary is qualified in its entirety by reference to the complete text of the 2021 Omnibus Plan, a copy of which is attached to this proxy statement/prospectus as Annex H. We urge our shareholders to read carefully the entire 2021 Omnibus Plan before voting on this proposal.

If approved by our shareholders, the 2021 Omnibus Plan will become effective upon the consummation of the Business Combination.

Summary of Material Terms of the 2021 Omnibus Plan

The following is a summary of the material features of the 2021 Omnibus Plan. The summary is qualified in its entirety by reference to the complete text of the 2021 Omnibus Plan attached as Annex H to this proxy statement/ prospectus.    

Purpose; Types of Awards

The purpose of the 2021 Omnibus Plan is to attract, retain and appropriately reward employees, directors, and consultants in order to motivate their performance in the achievement of Fathom’s business objectives and align their interests with the long-term interests of Fathom’s stockholders. To accomplish this purpose, the 2021 Omnibus Plan permits the granting of awards in the form of incentive stock options within the meaning of Section 422 of the Code, nonqualified stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance based awards (including performance shares, performance units and performance bonus awards), and other stock-based or cash-based awards.

Shares Subject to the 2021 Omnibus Plan

An amount equal to 13% of total outstanding shares of Fathom Class A common stock determined as of the Closing will be reserved and available for issuance under the 2021 Omnibus Plan. The maximum number of shares that may be issued pursuant to options intended to be incentive stock options will be equal to this reserve (and for the avoidance of doubt, will be set forth as a specified number of shares in the plan document, in Compliance with the Code). Non-employee directors may only be granted and paid up to $900,000 (when taken together with any fees paid to such non-employee director) in compensation per fiscal year; provided, that any Awards granted under the Plan or other compensation received by a non-employee director related to the settlement, conversion or substitution of the non-employee director’s award(s) under the Fathom Holdco, LLC Phantom Equity Bonus Plan shall not count against such limit..

If an award granted under the 2021 Omnibus Plan is forfeited, canceled, settled, or otherwise terminated the shares underlying that award will again become available for issuance under the 2021 Omnibus Plan. However, none of the following shares will be available for issuance under the 2021 Omnibus Plan: (i) shares delivered to

160

or withheld to pay withholding taxes or any applicable exercise price, (ii) shares subject to any exercised stock-settled SAR or options. In addition, any shares tendered to exercise outstanding options or other awards or repurchased on the open market using exercise price proceeds will not be available for issuance under the 2021 Omnibus Plan. Any substitute awards shall not reduce the shares authorized for grant under the 2021 Omnibus Plan.

Administration of the 2021 Omnibus Plan

The 2021 Omnibus Plan will be administered by the plan administrator, who is the board of directors of Fathom or a committee that the board of directors of Fathom designates. The plan administrator has the power to determine the terms of the awards granted under the 2021 Omnibus Plan, including the exercise price, the number of shares subject to each award, and the exercisability and vesting terms of the awards. The plan administrator also has the power to determine the persons to whom and the time or times at which awards will be made and to make all other determinations and take all other actions advisable for the administration of the 2021 Omnibus Plan. All decisions made by the administrator pursuant to the provisions of the 2021 Omnibus Plan will be final, conclusive and binding.

Participation

Participation in the 2021 Omnibus Plan will be open to employees, non-employee directors, or consultants, who have been selected as an eligible recipient under the 2021 Omnibus Plan by the plan administrator. Awards of incentive stock options, however, will be limited to employees of Fathom or its affiliates. As of September 30, 2021, we had 668 employees, all of whom following the consummation of the Business Combination may be eligible to participate in the 2021 Omnibus Plan. Awards will typically be limited to approximately 250 employees of Fathom and its subsidiaries. Following the consummation of the Business Combination, it is also expected that approximately 10 of our non-employee directors as well as 0 consultants will be eligible to participate in the 2021 Omnibus Plan.

Types of Awards

The types of awards that may be made under the 2021 Omnibus Plan are described below. All of the awards described below are subject to the conditions, limitations, restrictions, vesting and forfeiture provisions determined by the plan administrator, subject to the 2021 Omnibus Plan.

Stock Options

The 2021 Omnibus Plan provides for grants of both nonqualified and incentive stock options. A nonqualified stock option entitles the recipient to purchase our shares at a fixed exercise price. The exercise price per share will be determined by the compensation committee but such price will never be less than 100% of the fair market value of a share of common stock on the date of grant. Fair market value will generally be the closing price of a share of common stock on NYSE on the date of grant. Nonqualified stock options under the 2021 Omnibus Plan generally must be exercised within ten years from the date of grant. A nonqualified stock option is an option that does not meet the qualifications of an incentive stock option as described below.

An incentive stock option is a stock option that meets the requirements of Section 422 of the Code. Incentive stock options may be granted only to employees and the aggregate fair market value of a share of common stock determined at the time of grant with respect to incentive stock options that are exercisable for the first time by a participant during any calendar year may not exceed $100,000. No incentive stock option may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of our total combined voting power or that of any of our affiliates unless (i) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (ii) the term of the incentive stock option does not exceed five years from the date of grant.

161

Unless otherwise determined by the plan administrator, each vested and outstanding option granted under the 2021 Omnibus Plan will automatically be exercised on the last business day of the applicable option term, to the extent that, as of such date, (i) the exercise price of such option is less than the fair market value of a share, and (ii) the holder of such option remains actively in service.

Stock Appreciation Rights

A SAR entitles the holder to receive an amount equal to the difference between the fair market value of a share of common stock on the exercise date and the exercise price of the SAR (which may not be less than 100% of the fair market value of a share of our common stock on the grant date), multiplied by the number of shares of common stock subject to the SAR (as determined by the plan administrator). Unless otherwise determined by the plan administrator, each vested and outstanding SAR granted under the 2021 Omnibus Plan will automatically be exercised on the last business day of the applicable SAR term, to the extent that, as of such date, (i) the exercise price of such SAR is less than the fair market value of a share, and (ii) the holder of such SAR remains actively in service.

Restricted Stock

A restricted stock award is an award of shares of common stock that vest in accordance with the terms and conditions established by the plan administrator. The plan administrator will determine in the award agreement whether the participant will be entitled to receive dividends on such shares of restricted stock.

Restricted Stock Units

A restricted stock unit is a right to receive shares or the cash equivalent of common stock at a specified date in the future, subject to forfeiture of such right. If the restricted stock unit has not been forfeited, then on the date specified in the restricted stock unit grant, Fathom must deliver to the holder of the restricted stock unit unrestricted shares of common stock (or, in the plan administrator’s sole discretion, in cash equal to the shares that would otherwise be delivered, or partly in cash and partly in shares).

Other Stock-Based Awards

We may grant or sell to any participant a right or other interest that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of common stock, including unrestricted common stock under the 2021 Omnibus Plan or a dividend equivalent. A dividend equivalent is a right to receive payments, based on dividends with respect to shares of our common stock. To the extent that an award contains a right to receive dividends or dividend equivalents while the award remains unvested, the dividends and dividend equivalents will be accumulated and paid once and to the extent that the underlying award vests.

Other Cash-Based Awards

We may grant cash awards under the 2021 Omnibus Plan, including cash awards as a bonus or upon the attainment of certain performance goals.

Performance-Based Awards

We may grant an award conditioned on satisfaction of certain performance criteria. Such performance-based awards include performance-based restricted shares and restricted stock units. Any dividends or dividend equivalents payable or credited to a participate with respect to any unvested performance-based award will be subject to the same performance goals as the shares or units underlying the performance-based award.

162

Performance Goals

If the plan administrator determines that an award under the 2021 Omnibus Plan will be earned subject to the achievement of performance goals, the plan administrator may select one or more performance criteria upon which to grant such award, which may include, but are not limited to, any one or more of the following: earnings before interest and taxes; earnings before interest, taxes, depreciation and amortization; net operating profit after tax; cash flow; revenue; net revenues; sales; days sales outstanding; income; net income; operating income; net operating income, operating margin; earnings; earnings per share; return on equity; return on investment; return on capital; return on assets; return on net assets; total stockholder return; economic profit; market share; appreciation in the fair market value, book value or other measure of value of a share of common stock; expense/cost control; working capital; customer satisfaction; employee retention or employee turnover; employee satisfaction or engagement; environmental, health, or other safety goals; individual performance; strategic objective milestones; any other criteria specified by the plan administrator in its sole discretion; or, as applicable, any combination of, or a specified increase or decrease in, any of the foregoing.

Equitable Adjustments

In the event of a merger, consolidation, reclassification, recapitalization, spin-off, spin-out, repurchase or other reorganization or corporate transaction or event, extraordinary dividend, stock split or reverse stock split, combination or exchange of shares, or other change in corporate structure or payment of any other distribution, the maximum number and kind of shares of common stock reserved for issuance or with respect to which awards may be granted under the 2021 Omnibus Plan will be adjusted to reflect such event, and the plan administrator will make such adjustments as it deems appropriate and equitable in the number, kind and exercise price of common stock covered by outstanding awards made under the 2021 Omnibus Plan, and in any other matters that relate to awards and that are affected by the changes in the shares referred to in this section.

Change in Control

In the event of any proposed change in control (as defined in the 2021 Omnibus Plan), the plan administrator will take any action as it deems appropriate and equitable to effectuate the purposes of the 2021 Omnibus Plan and to protect the participants who hold outstanding awards under the 2021 Omnibus Plan, which action may include, without limitation, the following: (i) the continuation of any award, if Fathom is the surviving corporation; (ii) the assumption of any award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any award, provided, however, that any such substitution with respect to options and SARs shall occur in accordance with the requirements of Section 409A of the Code; or (iv) settlement of any award for the change in control price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the change in control price or if the plan administrator determines that the award cannot reasonably become vested pursuant to its terms, such award shall terminate and be canceled without consideration.

Amendment and Termination

The plan administrator may alter, amend, modify, or terminate the 2021 Omnibus Plan at any time, provided that the approval of our stockholders will be obtained for any amendment to the 2021 Omnibus Plan that requires stockholder approval under the rules of the stock exchange(s) on which our common stock is then listed or in accordance with other applicable law, including, but not limited to, an increase in the number of shares of our common stock reserved for issuance, a reduction in the exercise price of options or other entitlements, an extension of the maximum term of any award, or an amendment that grants the plan administrator additional powers to amend the 2021 Omnibus Plan. In addition, no modification of an award will, without the prior written consent of the participant, adversely alter or impair any rights or obligations under any award already granted under the 2021 Omnibus Plan, unless the plan administrator expressly reserved the right to do so at the time of the award.

163

Material U.S. Federal Income Tax Effects

The following discussion of certain relevant United States federal income tax effects applicable to certain awards granted under the 2021 Omnibus Plan is only a summary of certain of the United States federal income tax consequences as of the date hereof applicable to United States residents under the 2021 Omnibus Plan, and reference is made to the Code for a complete statement of all relevant federal tax provisions. No consideration has been given to the effects of foreign, state, local and other laws (tax or other) on the 2021 Omnibus Plan or on a participant, which laws will vary depending upon the particular jurisdiction or jurisdictions involved. In particular, participants who are stationed outside the United States may be subject to foreign taxes as a result of the 2021 Omnibus Plan.

Nonqualified Stock Options

An optionee subject to United States federal income tax will generally not recognize taxable income for United States federal income tax purposes upon the grant of a nonqualified stock option. Rather, at the time of exercise of the nonqualified stock option, the optionee will recognize ordinary income, subject to wage and employment tax withholding, and Fathom will be entitled to a deduction, in an amount equal to the excess of the fair market value of the shares on the date of exercise over the exercise price. If the shares acquired upon the exercise of a nonqualified stock option are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of such shares on the date of such exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the optionee), depending upon the length of time such shares were held by the optionee.

Incentive Stock Options

An optionee subject to United States federal income tax will generally not recognize taxable income for United States federal income tax purposes upon the grant of an incentive stock option (within the meaning of Section 422 of the Code) and Fathom will not be entitled to a deduction at that time. If the incentive stock option is exercised during employment or within 90 days following the termination thereof (or within one year following termination, in the case of a termination of employment due to death or disability, as such terms are defined in the 2021 Omnibus Plan), the optionee will not recognize any income and Fathom will not be entitled to a deduction. The excess of the fair market value of the shares on the exercise date over the exercise price, however, is includible in computing the optionee’s alternative minimum taxable income. Generally, if an optionee disposes of shares acquired by exercising an incentive stock option either within two years after the date of grant or one year after the date of exercise, the optionee will recognize ordinary income, and Fathom will be entitled to a deduction, in an amount equal to the excess of the fair market value of the shares on the date of exercise (or the sale price, if lower) over the exercise price. The balance of any gain or loss will generally be treated as a capital gain or loss to the optionee. If the shares are disposed of after the two-year and one-year periods described above, Fathom will not be entitled to any deduction, and the entire gain or loss for the optionee will be treated as a capital gain or loss.

SARs

A participant subject to United States federal income tax who is granted a SAR will not recognize ordinary income for United States federal income tax purposes upon receipt of the SAR. At the time of exercise, however, the participant will recognize ordinary income, subject to wage and employment tax withholding, equal to the value of any cash received and the fair market value on the date of exercise of any shares received. Fathom will not be entitled to a deduction upon the grant of a SAR, but generally will be entitled to a deduction for the amount of income the participant recognizes upon the participant’s exercise of the SAR. The participant’s tax basis in any shares received will be the fair market value on the date of exercise and, if the shares are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of the shares on the date of exercise will generally be taxable as long-term or short-term capital gain or loss (if the stock is a capital asset of the participant) depending upon the length of time such shares were held by the participant.

164

Restricted Stock

A participant subject to United States federal income tax generally will not be taxed upon the grant of a restricted stock award, but rather will recognize ordinary income for United States federal income tax purposes in an amount equal to the fair market value of the shares at the time the restricted stock is no longer subject to a substantial risk of forfeiture (within the meaning of the Code). Fathom generally will be entitled to a deduction at the time when, and in the amount that, the participant recognizes ordinary income on account of the lapse of the restrictions. A participant’s tax basis in the shares will equal the fair market value of those shares at the time the restrictions lapse, and the participant’s holding period for capital gains purposes will begin at that time. Any cash dividends paid on the shares before the restrictions lapse will be taxable to the participant as additional compensation (and not as dividend income). Under Section 83(b) of the Code, a participant may elect to recognize ordinary income at the time the restricted shares are awarded in an amount equal to their fair market value at that time, notwithstanding the fact that such shares are subject to restrictions and a substantial risk of forfeiture. If such an election is made, no additional taxable income will be recognized by such participant at the time the restrictions lapse, the participant will have a tax basis in the restricted shares equal to their fair market value on the date of their award, and the participant’s holding period for capital gains purposes will begin at that time. Fathom generally will be entitled to a tax deduction at the time when, and to the extent that, ordinary income is recognized by such participant.

Restricted Stock Units

A participant subject to United States federal income tax who is granted a restricted stock unit will not recognize ordinary income for United States federal income tax purposes upon the receipt of the restricted stock unit, but rather will recognize ordinary income in an amount equal to the fair market value of the shares at the time the award is settled into shares, subject to wage and employment tax withholding, and Fathom will have a corresponding deduction at that time.

Other Stock-Based and Other Cash-Based Awards

In the case of other stock-based and other cash-based awards, depending on the form of the award, a participant subject to United States federal income tax will not be taxed upon the grant of such an award, but, rather, will recognize ordinary income for United States federal income tax purposes when such an award vests or otherwise is free of restrictions. In any event, Fathom will be entitled to a deduction at the time when, and in the amount that, a participant recognizes ordinary income.

Tax Effects for Fathom

In addition to the tax impact to Fathom described above, Fathom’s deduction may also be limited by Section 280G or Section 162(m) of the Code. In general, Section 162(m) of the Code denies a publicly held corporation a deduction for United States federal income tax purposes for compensation in excess of $1,000,000 per year per covered employee.

New Plan Benefits

As of the date hereof, no awards have been granted under the 2021 Omnibus Plan. As explained in more detail below, the aggregate number of shares and aggregate total dollar value of potential future awards under the 2021 Omnibus Plan that may be made to any of our named executive officers or to our executive officers, non-executive officer employees or non-executive directors as a group are not yet determinable.

If the Business Combination and 2021 Omnibus Plan are approved, as previously disclosed, all vested time-based phantom unit awards under the Combined Phantom Plan outstanding immediately prior to the consummation of the Business Combination and held by individuals who are employed by or performing services

165

for Fathom OpCo or its subsidiaries or affiliates as of the Closing, will be forfeited and cancelled and such holders shall receive grants of restricted shares of Fathom Class A Common Stock under the 2021 Omnibus Plan. The restricted shares shall not vest until the date the Form S-8 is filed registering the 2021 Omnibus Plan shares; provided, that, the vested, unrestricted shares received in settlement of the Restricted Shares (as provided in the 2021 Omnibus Plan) shall be subject to such other transfer restrictions as set forth in the award agreements related thereto and described in more detail above under Post-Business Combination Company Executive Compensation. The exact number of restricted shares that will be granted to holders of vested time-based phantom unit awards is not currently known. Approximately 720 vested phantom unit awards under the Combined Phantom Plan were outstanding as of the date of the Business Combination Agreement.

In addition, if the Business Combination and 2021 Omnibus Plan are approved, as previously disclosed, all unvested time-based phantom unit awards and performance-based phantom unit awards held by individuals who are employed by or performing services for Fathom OpCo or its subsidiaries or affiliates as of the Closing shall be forfeited and cancelled and such holders shall receive grants of restricted stock units (“RSUs”) with respect to Fathom Class A Common Stock under the 2021 Omnibus Plan and such RSUs shall be subject to time-based vesting or performance-based vesting and such other transfer restrictions as set forth in the 2021 Omnibus Plan and the award agreements related thereto and described in more detail above under Post-Business Combination Company Executive Compensation. The exact number of RSUs that will be granted to holders of unvested time-based and performance-based phantom unit awards is not currently known. Approximately 12,941 unvested phantom unit awards under the Combined Phantom Plan were outstanding as of the date of the Business Combination Agreement.

The dollar value of any of potential restricted share and RSU award granted under the 2021 Omnibus Plan is not yet determinable. The exact number of vested phantom units to restricted shares and of unvested phantom units to RSUs, as previously disclosed above under the description of the Fathom OpCo Long-Term Equity Incentives, will equal 6.25% of the total value receivable by the Fathom OpCo common unit holders in connection with the Business Combination. Since the conversion ratio for phantom units is based on the total value payable to the common unit holders of Fathom OpCo, the amount receivable by each phantom unit holder at the Closing is not yet determinable. Such value is determined by taking the total merger consideration and subtracting the capital contributions and accrued interest owed to the Fathom OpCo preferred unit holders. Because interest accrues daily, the exact amount received by the Fathom OpCo common unit holders will not be determinable until the date of Closing is determinable. At such time, 6.25% of the value received by Fathom OpCo common unit holders will be divided by $10.00 (the price per share of one share of Fathom Class A common stock, determined as of the Closing) resulting in the total share pool that will be used to determine the number of shares each phantom unit holder will receive under the 2021 Omnibus Plan in the form of restricted shares or RSUs, respectively. Additionally, the awards granted under the 2021 Omnibus Plan in respect of phantom units will depend on a number of factors, including the fair market value of Fathom Class A Common Stock on future dates, the service milestones achieved by participants prior to the Closing, and the extent to which any applicable performance goals necessary for vesting or payment are achieved.

Registration with the SEC

If the 2021 Omnibus Plan is approved by our stockholders and becomes effective, Fathom is expected to file a registration statement on Form S-8 registering the shares reserved for issuance under the 2021 Omnibus Plan as soon as reasonably practicable after becoming eligible to use such form.

Equity Compensation Plan Information

Altimar II did not maintain, or have any securities authorized for issuance under, any equity compensation plans as of December 31, 2020.

Recommendation of the Altimar II Board of Directors

ALTIMAR II’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS SHAREHOLDERS VOTE “FOR” THE EQUITY INCENTIVE PLAN PROPOSAL.

167

PROPOSAL NO. 8 — THE ESPP PROPOSAL

Overview

The Board expects to approve the Fathom 2021 Employee Stock Purchase Plan (the “ESPP”) and adopt the ESPP, effective as of the Closing, subject to the approval of our shareholders. We are seeking shareholder approval of the ESPP (i) to qualify the ESPP as an “employee stock purchase plan” under Section 423 of the Code and the related regulations and (ii) in order to comply with the NYSE listing rules.

The purpose of the ESPP is to encourage employee stock ownership, thus aligning employee interests with those of our stockholders, and to enhance the ability of Fathom to attract, motivate and retain qualified employees. We believe that the ESPP will offer a convenient means for our employees who might not otherwise own our common stock to purchase and hold shares.

This summary is qualified in its entirety by reference to the complete text of the ESPP, a copy of which is attached to this proxy statement/prospectus as Annex I. We urge our shareholders to read carefully the entire ESPP before voting on this proposal. If approved by our shareholders, the ESPP will become effective upon the consummation of the Business Combination.

Summary of Material Terms of the ESPP

The following is a summary of the material features of the ESPP. The summary is qualified in its entirety by reference to the complete text of the ESPP attached as Annex I to this proxy statement/ prospectus.

Shares Subject to the ESPP

The 2021 ESPP will cover an aggregate of the total number of shares of Fathom Class A common stock that will be reserved and that may be issued under the ESPP will automatically increase on the first trading day of each calendar year, beginning with calendar year 2023, by a number of shares equal to 1% of the total number of shares of Fathom Class A common stock outstanding on the last day of the prior calendar year. The plan administrator may act prior to January 1 of a given year to provide that there will be no increase in the share reserve for that year, or that the increase in the share reserve will be smaller than as provided in the ESPP.

To prevent dilution or enlargement of the rights of participants under the ESPP, appropriate adjustments will be made if any change is made to our outstanding common stock by reason of any merger, reorganization, consolidation, recapitalization, dividend or distribution, stock split, reverse stock split, spin-off or similar transaction or other change in corporate structure affecting our common stock or its value.

ESPP Participants

Generally, all of our employees will be eligible to participate if they are customarily employed by us, or any participating subsidiary, for at least 20 hours per week and more than five months in any calendar year. However, the plan administrator has certain discretion to vary the eligibility requirements. Specifically, the plan administrator may, prior to an enrollment date for all options granted on such enrollment date in an offering, determine that any of the following is or is not eligible to participate in such offering period: an employee who (i) has not completed at least two years of service (or a lesser period of time determined by the plan administrator) since his or her last hire date, (ii) customarily works not more than 20 hours per week (or a lesser period of time determined by the plan administrator), (iii) customarily works not more than five months per calendar year (or a lesser period of time determined by the plan administrator), (iv) is a highly compensated employee within the meaning of Section 414(q) of the Code or (v) is a highly compensated employee within the meaning of Section 414(q) of the Code with compensation above a certain level or is an officer or subject to disclosure requirements under Section 16(a) of the Exchange Act. Following the consummation of the Business Combination, it is expected that approximately 668 employees, 0 non-employee directors and 0 consultants will be eligible to participate in the ESPP.

168

However, an employee may not be granted rights to purchase shares of Fathom Class A common stock under the ESPP if such employee immediately after the grant would own capital stock possessing 5% or more of the total combined voting power or value of all classes of our capital stock; or holds rights to purchase shares of our common stock under all of our employee stock purchase plans that accrue at a rate that exceeds $25,000 worth of shares of our common stock for each calendar year.

Administration

The 2021 ESPP will be administered by the Board or any committee designated by the Board. The plan administrator has broad power to make determinations under the ESPP, to interpret the terms of the ESPP and to establish rules and regulations for its administration. The plan administrator determines whether offers will be made and the beginning and ending dates of the related purchase periods. The plan administrator will have full and exclusive discretionary authority to construe, interpret and apply the terms of the ESPP, delegate ministerial duties to any of our employees, supply omissions or correct defects in the ESPP, designate separate offerings under the ESPP, designate our subsidiaries and affiliates as participating in the ESPP, determine eligibility, adjudicate all disputed claims filed under the ESPP and establish procedures that it deems necessary for the administration of the ESPP. The plan administrator’s findings, decisions and determinations are final and binding on all participants to the full extent permitted by law.

Purchases Under ESPP

The plan administrator will determine the length of each offering period. An offering period may be more than 27 months. We anticipate initiating the ESPP with 12-month offering periods, with each offering period having two 6-month purchase periods. The plan administrator determines the purchase price at which shares may be purchased by participants, which will not be less than the lesser of 85% of the fair market value per share of the Fathom Class A common stock on the first day of the purchase period or 85% of the fair market value per share on the last day of the purchase period. The plan administrator will determine whether the participants will be subject to any minimum holding period for the shares of common stock purchased under the ESPP. The plan administrator currently intends to require a minimum holding period of six months from the end of each applicable purchase period.

Prior to the first day of each offering period, each participant will make an election to participate during the offering period. At the end of each purchase period, the participant will receive a number of shares, determined on the last day of the purchase period, equal to the payroll deductions credited during the purchase period divided by the applicable purchase price, except that no fractional shares may be purchased under the ESPP. We intend to initially set the purchase price at a 15% discount from the lesser of the closing price on the first day of the offering period and the closing price on the purchase date. A participant may not purchase shares with a fair market value greater than $25,000 under the ESPP in any calendar year. The plan administrator may, however, modify at its discretion the discount, purchase period, purchase date and other aspects of the ESPP design within the ESPP parameters from time to time.

Participants may purchase shares only by submitting an election form during the election period established by the plan administrator prior to the beginning of each offering period, stating the participant’s election to have after-tax payroll deductions made for the purpose of participating in the ESPP. After initial enrollment in the ESPP, payroll deductions will continue from offering period to offering period unless the participant makes another election to terminate his or her payroll deductions, terminates his or her employment with Fathom or becomes ineligible to participate in the ESPP. The amounts deducted will be credited to the participant’s account under the ESPP until the purchase date, but we will not pay any interest on the deducted amounts.

Participants may end their participation at any time during an offering period in accordance with any applicable insider trading policies by submitting to Fathom’s stock administration office a written notice of withdrawal in the form determined by the plan administrator or by following an electronic or other withdrawal

169

procedure determined by the plan administrator. In such case, participants will be paid their accrued contributions that have not yet been used to purchase shares of our common stock. Additionally, participation ends automatically upon termination of employment with us. If sufficient shares are not available in any purchase period under the ESPP, the available shares will be allocated pro rata among the participants in that purchase period in a uniform manner as determined by the plan administrator for that purchase period. Any amounts not applied to the purchase of common stock will be refunded to the participants after the end of the purchase period without interest.

Restriction on Transfer

The right to acquire shares under the ESPP is not transferable.

Change in Control

If there is a change in control of Fathom, each right to purchase shares under the ESPP will be assumed or an equivalent right to purchase shares will be substituted by the successor corporation or a parent or subsidiary of such corporation. If the successor corporation fails to assume or substitute for the ESPP purchase rights, the plan administrator will shorten the offering period covered by such ESPP purchase right by setting a new exercise date on which such offering period will end. The new exercise date will occur before the change in control. The plan administrator will notify each participant in writing or electronically prior to the new exercise date, that the exercise date for the participant’s purchase rights has been changed to the new exercise date and the participant’s purchase rights will be exercised automatically on the new exercise date, unless prior to such date the participant has withdrawn from the offering period.

Amendment and Termination of the ESPP

The plan administrator has the authority to amend, suspend or terminate the ESPP unless the amendment requires stockholder approval pursuant to Section 423 of the Code, other applicable laws or stock exchange rules. No amendment or termination will adversely affect any right to purchase shares that has been granted under the ESPP without the consent of the participant. The 2021 ESPP shall continue in effect for ten (10) years after the date of stockholder approval.

Application of Funds

We may use the proceeds from the sale of our common stock pursuant to the ESPP for any corporate purpose.

Material U.S. Federal Income Tax Consequences

The following discussion of certain relevant United States federal income tax consequences applicable to the purchase of shares under the ESPP is only a summary of certain of the United States federal income tax consequences applicable to United States residents under the ESPP as of the date hereof, and reference is made to the Code for a complete statement of all relevant federal tax provisions. No consideration has been given to the effects of foreign, state, local and other laws (tax or other) on the ESPP or on a participant, which laws will vary depending upon the particular jurisdiction or jurisdictions involved. In particular, participants who are stationed outside the United States may be subject to foreign taxes as a result of the ESPP.

No taxable income will be recognized by a participant, and no deductions will be allowable to Fathom, upon either the grant or the exercise of rights to purchase shares. A participant only will recognize income when the shares acquired under the ESPP are sold or otherwise disposed of.

The tax due upon sale or other disposition of the acquired shares depends on the length of time that the participant holds the shares.

170

If the participant sells or otherwise disposes of the purchased shares within two years after the start date of the offering period pursuant to which the shares were acquired or within one year after the actual purchase date of those shares, the participant generally will recognize ordinary income in the year of sale or disposition equal to the amount by which the fair market value of the shares on the purchase date exceeded the purchase price paid for those shares. Fathom will be entitled to a corresponding income tax deduction for the amount of income recognized for the taxable year in which such disposition occurs. The amount of this ordinary income will be added to the participant’s basis in the shares, and any additional gain or loss recognized upon the sale or disposition will be a capital gain or loss. If the shares have been held for more than one year since the date of purchase, the gain or loss will be long-term capital gain.

If the participant sells or disposes of the purchased shares more than two years after the start date of the offering period pursuant to which the shares were acquired and more than one year after the actual purchase date of those shares, then the participant generally will recognize ordinary income in the year of sale or disposition equal to the lesser of (i) the amount by which the fair market value of the shares on the sale or disposition date exceeded the purchase price paid for those shares, or (ii) 15% of the fair market value of the shares on the start date of that offering period. Any additional gain upon the disposition will be taxed as a long-term capital gain. Alternatively, if the fair market value of the shares on the date of the sale or disposition is less than the purchase price, there will be no ordinary income and any loss recognized will be a long-term capital loss. Fathom will not be entitled to an income tax deduction with respect to such disposition.

The tax consequences to a participant may vary depending upon the participant’s individual situation. In addition, various state laws may provide for tax consequences that vary significantly from those described above.

New Plan Benefits

Participation in the ESPP is entirely within the discretion of the eligible employees. Because we cannot presently determine the participation levels by employee, the rate of contributions by employees and the eventual purchase price under the ESPP, it is not possible to determine the value of benefits which may be obtained by executive officers and other employees under the ESPP. Non-employee directors are not eligible to participate in the ESPP.

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that the Fathom 2021 Employee Stock Purchase Plan (annexed to the proxy statement/prospectus as Annex I) be approved and adopted in all respects.”

Vote Required for Approval

If the Business Combination Proposal is not approved, the ESPP Proposal will not be presented at the Special Meeting. The approval of this ESPP Proposal requires an ordinary resolution under Cayman Islands law, being the majority of the holders of the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting.

Failure to submit a proxy or to vote in person at the Special Meeting, an abstention from voting or a broker non-vote will have no effect on the ESPP.

The Business Combination is conditioned upon the approval of the ESPP Proposal, subject to the terms of the Business Combination Agreement. Notwithstanding the approval of the ESPP Proposal, if the Business Combination is not consummated for any reason, the actions contemplated by the ESPP Proposal will not be effected.

171

The Sponsor and the other Altimar II Founders have agreed to vote the founder shares and any Class A ordinary shares owned by them in favor of the ESPP Proposal. See “The Business Combination Agreement—Related Agreements—Forfeiture and Support Agreement” for more information.

172

PROPOSAL NO. 9 — THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal, if adopted, will allow Altimar II’s board of directors to adjourn the Special Meeting to a later date or dates, if necessary, to permit further solicitation of proxies if, based upon the tabulated vote at the time of the Special Meeting, there are not sufficient votes to approve the Business Combination Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal or the ESPP Proposal or if Altimar II’s board of directors determines that one or more of the closing conditions under the Business Combination Agreement is not satisfied or waived. In no event will Altimar II’s board of directors adjourn the Special Meeting or consummate the Business Combination beyond the date by which it may properly do so under our Existing Organizational Documents and Cayman Islands law.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by Altimar II’s shareholders, Altimar II’s board of directors may not be able to adjourn the Special Meeting to a later date in the event that there are insufficient votes for the approval of the Business Combination Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Business Combination Issuance Proposal, the Equity Incentive Plan Proposal or the ESPP Proposal. If we do not consummate the Business Combination and fail to complete an initial business combination by February 9, 2023 (subject to the requirements of law), we will be required to dissolve and liquidate our Trust Account by returning the then remaining funds in such account to the public shareholders.

Resolution to be Voted Upon

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that the adjournment of the EGM to a later date or dates to be determined by the chairman of the EGM, if necessary, to permit further solicitation and vote of proxies be confirmed, ratified and approved in all respects.”

Vote Required for Approval

The approval of the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the majority of the holders of the ordinary shares who, being present in person (or represented by proxy) and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting. Abstentions and broker non-votes, while considered present for purposes of establishing quorum, will not count as a vote cast at the Special Meeting.

Failure to submit a proxy or to vote in person at the Special Meeting, an abstention from voting or a broker non-vote will have no effect on the Adjournment Proposal.

The Business Combination is not conditioned upon the approval of the Adjournment Proposal.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following summary is a discussion of U.S. federal income tax considerations of the Domestication, an exercise of Redemption Rights and the Business Combination generally applicable to holders of Altimar II ordinary shares or warrants and Fathom common stock or warrants, and with respect to non-U.S. holders (as defined below) the ownership and disposition of Fathom common stock and warrants after the Domestication and Business Combination. This section applies only to holders that hold their Altimar II ordinary shares and warrants or Fathom common stock and warrants as capital assets for U.S. federal income tax purposes (generally, property held for investment) and does not address the Sponsor or their affiliates, representatives, employees or other stakeholders.

This section is general in nature and does not discuss all aspects of U.S. federal income taxation that might be relevant to a particular holder in light of such holder’s circumstances or status, nor does it address tax considerations applicable to a holder subject to special rules, including:

• financial institutions;

• governments or agencies or instrumentalities thereof;

• insurance companies;

• dealers or traders subject to a mark-to-market method of tax accounting with respect to Altimar II ordinary shares or warrants or Fathom common stock or warrants;

• persons holding Altimar II ordinary shares or warrants or Fathom common stock or warrants as part of a “straddle,” hedge, integrated transaction or similar transaction, or persons deemed to sell the Altimar II ordinary shares or warrants or Fathom common stock or warrants under constructive sale provisions of the Code;

• U.S. holders (as defined below) whose functional currency is not the U.S. dollar;

• partnerships or other pass-through entities for U.S. federal income tax purposes or investors in such entities;

• holders who are controlled foreign corporations or passive foreign investment companies;

• regulated investment companies;

• real estate investment trusts;

• persons who acquired Altimar II ordinary shares or warrants or Fathom common stock or warrants through the exercise or cancellation of employee stock options or otherwise as compensation for their services;

• U.S. holders (as defined below) owning (actually or constructively) 10% or more of the total combined voting power of all classes of stock entitled to vote of, or 10% or more of the total value of all classes of shares of, Altimar II or Fathom;

• U.S. holders (as defined below) that hold their Altimar II ordinary shares or warrants and Fathom common stock or warrants through a non-U.S. broker or other non-U.S. intermediary;

• persons who are, or may become, subject to the expatriation provisions of the Code;

• persons that are subject to “applicable financial statement rules” under Section 451(b); or

• tax-exempt entities.

This discussion is based on the Code, and administrative pronouncements, judicial decisions and final, temporary and proposed Treasury Regulations all as of the date hereof, changes to any of which subsequent to the date of this prospectus may affect the tax consequences described herein (possibly with retroactive effect).

174

This discussion does not take into account proposed changes in such tax laws and does not address any aspect of state, local or non-U.S. taxation, or any U.S. federal taxes other than income taxes (such as estate or gift tax consequences, the alternative minimum tax or the Medicare tax on investment income). Each of the foregoing is subject to change, possibly with retroactive effect. You should consult your tax advisors with respect to the application of U.S. federal tax laws to your particular situation, as well as any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction.

We have not and do not intend to seek any rulings from the U.S. Internal Revenue Service (the “IRS”) regarding the Domestication, an exercise of Redemption Rights, the Business Combination, or any other matters discussed herein. There can be no assurance that the IRS will not take positions concerning the tax consequences of the transactions that are inconsistent with the considerations discussed below or that any such positions would not be sustained by a court.

Because Altimar II units (each unit consisting of one Altimar II Class A ordinary share and one Altimar II warrant) can be separated into their component parts at the option of the holder, a beneficial owner of an Altimar II public unit should be treated as the owner of the underlying Altimar II securities for U.S. federal income tax purposes. The discussion below with respect to Altimar II securities should also apply to holders of Altimar II public units (as the deemed owner of the underlying Altimar II securities). References in this discussion to “ordinary shares” refers to Altimar II Class A ordinary shares and references in this discussion to “common stock” refers to Fathom common stock and references to “warrants” refer to Altimar II warrants or Fathom warrants, as the context may require.

If a partnership (or any entity or arrangement so characterized for U.S. federal income tax purposes) holds Altimar II ordinary shares or warrants or Fathom common stock or warrants, the tax treatment of such partnership and a person treated as a partner of such partnership will generally depend on the status of the partner and the activities of the partnership. Partnerships holding any Altimar II ordinary shares or warrants or Fathom common stock or warrants and persons that are treated as partners of such partnerships should consult their tax advisors as to the particular U.S. federal income tax consequences of the Domestication, an exercise of Redemption Rights and the Business Combination to them.

THE FOLLOWING IS FOR INFORMATIONAL PURPOSES ONLY. ALL SHAREHOLDERS SHOULD CONSULT THEIR TAX ADVISORS REGARDING THE TAX CONSEQUENCES OF THE DOMESTICATION, AN EXERCISE OF REDEMPTION RIGHTS AND THE BUSINESS COMBINATION, INCLUDING THE EFFECTS OF U.S. FEDERAL, STATE AND LOCAL AND NON-U.S. TAX LAWS.

U.S. Holders

This section applies to you if you are a “U.S. holder.” A U.S. holder is a beneficial owner of Altimar II ordinary shares or warrants or Fathom common stock or warrants who or that is, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States as determined for U.S. federal income tax purposes;

• a corporation (or other entity treated as a corporation) that is created or organized (or treated as created or organized) under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

• a trust, if (i) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more “United States persons” (within the meaning of the Code) have the authority to control all substantial decisions of the trust, or (ii) the trust has validly elected to be treated as a United States person for U.S. federal income tax purposes.

175

Consequences of the Domestication to U.S. Holders—F Reorganization

The U.S. federal income tax consequences of the Domestication will depend primarily upon whether the Domestication qualifies as a “reorganization” within the meaning of Section 368 of the Code.

Under Section 368(a)(1)(F) of the Code, a reorganization (an “F Reorganization”) is a “mere change in identity, form or place of organization of one corporation, however effected.” Pursuant to the Domestication, Altimar II will change its jurisdiction of incorporation from the Cayman Islands to Delaware, and, after the Domestication will change its name to Fathom Digital Manufacturing Corporation.

Based on, and subject to, the assumptions, qualifications and limitations set forth in the opinion included as Exhibit 8.1 hereto, it is the opinion of Paul, Weiss, Rifkind, Wharton & Garrison LLP that the Domestication should qualify as an F Reorganization for U.S. federal income tax purposes. However, due to the absence of direct guidance on the application of Section 368(a)(1)(F) of the Code to a statutory conversion of a corporation holding only investment-type assets such as Altimar II, this result is not entirely clear. Accordingly, due to the absence of such guidance, it is not possible to predict whether the IRS or a court considering the issue would take a contrary position. The remainder of this discussion assumes the Domestication so qualifies. Assuming the Domestication so qualifies, U.S. holders generally will not recognize taxable gain or loss on the Domestication for U.S. federal income tax purposes, except as provided below under the caption headings “— Effect of Section 367 to U.S. Holders” and “— PFIC Considerations”, and the Domestication will be treated for U.S. federal income tax purposes as if Altimar II (i) transferred all of its assets and liabilities to Fathom in exchange for all of the outstanding common stock and warrants of Fathom; and (ii) then distributed the common stock and warrants of Fathom to the shareholders and warrant holders of Altimar II in liquidation of Altimar II. The taxable year of Altimar II will be deemed to end on the date of the Domestication.

Assuming the Domestication qualifies as an F Reorganization: (i) the tax basis of a share of Fathom common stock or a Fathom warrant received by a U.S. holder in the Domestication will equal the U.S. holder’s adjusted tax basis in the Altimar II ordinary share or warrant, as the case may be, surrendered in exchange therefor, increased by any amount included in the income of such U.S. holder as a result of Section 367 of the Code (as discussed below) and (ii) the holding period for a share of Fathom common stock or a Fathom warrant received by a U.S. holder will include such U.S. holder’s holding period for the Altimar II ordinary share or warrant surrendered in exchange therefor.

If the Domestication fails to qualify as an F Reorganization, a U.S. holder generally would recognize gain or loss with respect to its Altimar II ordinary shares and warrants in an amount equal to the difference between the fair market value of Fathom common stock and warrants received in the Domestication and the U.S. holder’s adjusted tax basis in its Altimar II ordinary shares and warrants surrendered in the Domestication. In such event, such U.S. holder’s basis in Fathom common stock and warrants would be equal to their fair market value on the date of the Domestication, and such U.S. holder’s holding period for Fathom common stock and warrants would begin on the day following the date of the Domestication. Shareholders who hold different blocks of Altimar II ordinary shares and warrants (generally, ordinary shares and warrants of Altimar II purchased or acquired on different dates or at different prices) should consult their tax advisors to determine how the above rules apply to them.

Because the Domestication will occur prior to the redemption of U.S. holders that exercise Redemption Rights, U.S. holders exercising such Redemption Rights will be subject to the potential tax consequences of the Domestication. All U.S. holders considering exercising Redemption Rights are urged to consult with their tax advisors with respect to the potential tax consequences of the Domestication and an exercise of Redemption Rights to them.

ALL U.S. HOLDERS CONSIDERING EXERCISING REDEMPTION RIGHTS ARE URGED TO CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE POTENTIAL TAX CONSEQUENCES OF THE DOMESTICATION AND AN EXERCISE OF REDEMPTION RIGHTS TO THEM.

176

Effect of Section 367 to U.S. Holders

Section 367 of the Code applies to certain non-recognition transactions involving foreign corporations, including a domestication of a foreign corporation in an F Reorganization. Section 367 of the Code imposes income tax on certain U.S. persons in connection with transactions that would otherwise be tax-free. Section 367(b) of the Code generally will apply to U.S. holders that exchange Altimar II ordinary shares for Fathom common stock as part of the Domestication. Because the Domestication will occur immediately prior to the redemption of holders that exercise Redemption Rights, U.S. holders exercising Redemption Rights will be subject to the potential tax consequences of Section 367 of the Code as a result of the Domestication.

U.S. Holders That Own Altimar II Ordinary Shares with a Fair Market Value of $50,000 or More But Less Than 10 Percent of Altimar II

A U.S. holder who, at the time of the Domestication, beneficially owns (directly, indirectly, or constructively, including as a result of applicable attribution rules that would take into account a holder’s ownership of Altimar II warrants) Altimar II ordinary shares with a fair market value of $50,000 or more but less than 10% of the total combined voting power of all classes of Altimar II ordinary shares entitled to vote and less than 10% of the total value of all classes of Altimar II ordinary shares will generally recognize gain (but not loss) with respect to the Fathom common stock received in the Domestication unless such holder elects to recognize the “all earnings and profits” amount attributable to such holder as described below. Complex attribution rules apply in determining whether a U.S. holder owns 10% or more of the total combined voting power of all classes of our ordinary shares entitled to vote or owns 10% or more of the total value of all classes of our ordinary shares. All U.S. holders are urged to consult their tax advisors with respect to those attribution rules.

Unless a U.S. holder makes the “all earnings and profits” election as described below, such holder generally must recognize gain (but not loss) with respect to its Altimar II ordinary shares exchanged for Fathom common stock pursuant to the Domestication. Any such gain would be equal to the excess of the fair market value of such Fathom common stock received over the U.S. holder’s adjusted tax basis in the Altimar II ordinary shares deemed to be surrendered in exchange therefor. Subject to the PFIC rules discussed below, such gain would be capital gain, and should be long-term capital gain if the U.S. holder held the Altimar II ordinary shares for longer than one year.

In lieu of recognizing any gain as described in the preceding paragraph, a U.S. holder may elect to include in income the “all earnings and profits amount” attributable to its Altimar II ordinary shares. There are, however, strict conditions for making this election. This election must comply with applicable Treasury Regulations and generally must include, among other things:

• a statement that the Domestication is a Section 367(b) exchange;

• a complete description of the Domestication;

• a description of any stock, securities or other consideration transferred or received in the Domestication;

• a statement describing the amounts required to be taken into account for U.S. federal income tax purposes as income or as an adjustment to basis, earnings and profits or other tax attributes;

• a statement that the U.S. holder is making the election that includes (A) a copy of the information that the U.S. holder received from Altimar II (or Fathom) establishing and substantiating the U.S. holder’s “all earnings and profits amount” with respect to the U.S. holder’s Altimar II ordinary shares, and (B) a representation that the U.S. holder has notified Altimar II (or Fathom) that the U.S. holder is making the election; and

• certain other information required to be furnished with the U.S. holder’s tax return or otherwise furnished pursuant to the Code or the Treasury Regulations.

177

The election must be attached by the U.S. holder to its timely filed U.S. federal income tax return for the year of the Domestication, and the U.S. holder must send notice of making the election to Fathom no later than the date such tax return is filed. In connection with this election, Altimar II intends to provide each U.S. holder eligible to make such an election with information regarding Altimar II’s earnings and profits upon request. Altimar II does not expect that Altimar II’s cumulative earnings and profits will be material at the time of domestication.

U.S. HOLDERS ARE STRONGLY URGED TO CONSULT A TAX ADVISOR REGARDING THE CONSEQUENCES OF MAKING THE ELECTION DESCRIBED ABOVE AND THE APPROPRIATE FILING REQUIREMENTS WITH RESPECT TO SUCH ELECTION.

U.S. Holders that Own Altimar II Ordinary Shares with a Fair Market Value of Less Than $50,000

A U.S. holder who, at the time of the Domestication, owns (or is considered to own) Altimar II ordinary shares with a fair market value of less than $50,000 should not be required to recognize any gain or loss under Section 367(b) of the Code in connection with the Domestication, and generally should not be required to include any part of the “all earnings and profits amount” in income.

ALL U.S. HOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE DOMESTICATION TO THEM.

PFIC Considerations

In addition to Section 367(b) of the Code, the Domestication may be a taxable event to U.S. holders to the extent that Section 1291(f) of the Code applies, if Altimar II is or ever was a PFIC under Section 1297 of the Code.

General. A foreign corporation generally will be a PFIC for U.S. federal income tax purposes with respect to a taxable year of the foreign corporation if:

• at least 75% of its gross income in such taxable year, including its pro rata share of the gross income of any corporation in which it is considered to own at least 25% of the shares by value, is passive income; or

• at least 50% of its assets in such taxable year, ordinarily determined based on fair market value and averaged quarterly over the year, including its pro rata share of the assets of any corporation in which it is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income.

Passive income generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets.

Pursuant to a start-up exception, a corporation will not be a PFIC for the first taxable year the corporation has gross income (the “start-up year”), if (i) no predecessor of the corporation was a PFIC; (ii) the corporation satisfies the IRS that it will not be a PFIC for either of the first two taxable years following the start-up year; and (iii) the corporation is not in fact a PFIC for either of those two years. Altimar II believes, although subject to uncertainty, that Altimar II’s 2021 taxable year may be the start-up year and that Altimar II may not be treated as a PFIC for 2021. The application of the start-up exception will depend, in part, on whether the Domestication is consummated in 2021. In addition, the application of the start-up exception to the present transaction involves the application of complicated rules with respect to which there is no clear authority. Accordingly, there can be no assurance with respect to Altimar II’s status as a PFIC for 2021. All holders are urged to consult their tax advisors concerning the application of the PFIC rules to Altimar II under such holder’s particular circumstances, including the potential to make a “qualified electing fund” election or a protective “qualified electing fund” election.

178

Consequences if a PFIC. If Altimar II is determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. holder of Altimar II’s ordinary shares or warrants and, in the case of ordinary shares, the U.S. holder did not make a timely qualified electing fund (“QEF”) election for Altimar II’s first taxable year as a PFIC in which the U.S. holder held (or was deemed to hold) such ordinary shares, did not make a QEF election along with a “purging election,” or did not make a timely mark-to-market election as discussed below, then as described below, such holder generally will be subject to special rules with respect to: (i) any gain recognized by the U.S. holder on the sale or other disposition of its Altimar II ordinary shares or warrants; and (ii) any “excess distribution” made to the U.S. holder (generally, any distributions to such U.S. holder during a taxable year of the U.S. holder that are greater than 125% of the average annual distributions received by such U.S. holder in respect of the ordinary shares during the three preceding taxable years of such U.S. holder or, if shorter, such U.S. holder’s holding period for the Altimar II ordinary shares).

Under these rules:

• the U.S. holder’s gain or excess distribution will be allocated ratably over the U.S. holder’s holding period for the Altimar II ordinary shares or warrants;

• the amount of gain allocated to the U.S. holder’s taxable year in which the U.S. holder recognized the gain or received the excess distribution, or to the period in the U.S. holder’s holding period before the first day of the first taxable year in which Altimar II is a PFIC, will be taxed as ordinary income;

• the amount of gain allocated to other taxable years (or portions thereof) of the U.S. holder and included in its holding period will be taxed at the highest tax rate in effect for that year and applicable to the U.S. holder; and

• the interest charge generally applicable to underpayments of tax will be imposed in respect of the tax attributable to each such other taxable year of the U.S. holder.

QEF Election. In general, if Altimar II is determined to be a PFIC, a U.S. holder may avoid the PFIC tax consequences described above in respect to its Altimar II ordinary shares by making a timely QEF election to include in income its pro rata share of Altimar II’s net capital gains (as long-term capital gain) and other earnings and profits (as ordinary income), on a current basis, in each case whether or not distributed, in each taxable year of the U.S. holder in which or with which Altimar II’s taxable year ends. The QEF election is made on a shareholder-by-shareholder basis and, once made, can be revoked only with the consent of the IRS. A U.S. holder generally makes a QEF election by attaching a completed IRS Form 8621 (Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund), including the information provided in a “PFIC Annual Information Statement,” to a timely filed U.S. federal income tax return for the tax year to which the election relates. Retroactive QEF elections generally may be made only by filing a protective statement with such return and if certain other conditions are met or with the consent of the IRS. U.S. holders should consult their tax advisors regarding the availability and tax consequences of a retroactive QEF election under their particular circumstances. However, in order to comply with the requirements of a QEF election, a U.S. holder must receive a PFIC annual information statement from Altimar II. Upon written request, Altimar II will endeavor to provide to a U.S. holder such information as the IRS may require, including a PFIC annual information statement, in order to enable the U.S. holder to make and maintain a QEF election, but there can be no assurance that we will timely provide such required information.

A U.S. holder may not make a QEF election with respect to its Altimar II warrants. As a result, if a U.S. holder of Altimar II warrants sells or otherwise disposes of such warrants, any gain recognized will be subject to the special tax and interest charge rules treating the gain as an excess distribution, as described above, if Altimar II was a PFIC at any time during the period the U.S. holder held the Altimar II warrants.

Mark-to-Market Election. Alternatively, if a U.S. holder, at the close of its taxable year, owns shares in a PFIC that are treated as marketable stock, the U.S. holder may make a mark-to-market election with respect to such shares for such taxable year. If the U.S. holder makes a valid mark-to-market election for the first taxable

179

year of the U.S. holder in which the U.S. holder holds (or is deemed to hold) Altimar II ordinary shares and for which Altimar II is determined to be a PFIC, such holder generally will not be subject to the PFIC rules described above in respect of its ordinary shares. Instead, in general, the U.S. holder will include as ordinary income each year the excess, if any, of the fair market value of its ordinary shares at the end of its taxable year over the adjusted basis in its ordinary shares. The U.S. holder also will be allowed to take an ordinary loss in respect of the excess, if any, of the adjusted basis of its ordinary shares over the fair market value of its ordinary shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). The U.S. holder’s basis in its Altimar II ordinary shares will be adjusted to reflect any such income or loss amounts, and any further gain recognized on a sale or other taxable disposition of the Altimar II ordinary shares will be treated as ordinary income. Currently, a mark-to-market election may not be made with respect to warrants.

The mark-to-market election is available only for stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including the New York Stock Exchange (on which Altimar II ordinary shares have been listed), or on an exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. U.S. holders are urged to consult their tax advisors regarding the availability and tax consequences of a mark-to-market election in respect to our ordinary shares under their particular circumstances.

Effect of PFIC Rules on the Domestication. Even if the Domestication qualifies as an F Reorganization, Section 1291(f) of the Code requires that, to the extent provided in Treasury Regulations, a U.S. person that disposes of stock of a PFIC (including rights to acquire stock of a PFIC) must recognize gain notwithstanding any other provision of the Code. No final Treasury Regulations are currently in effect under Section 1291(f) of the Code. Proposed Treasury Regulations under Section 1291(f), or the “Proposed Regulations”, were promulgated in 1992, with a retroactive effective date once they become finalized. If finalized in their current form, the Proposed Regulations may require taxable gain recognition by a U.S. holder subject to the PFIC rules with respect to its exchange of Altimar II ordinary shares or warrants for Fathom common stock or warrants in the Domestication if Altimar II were classified as a PFIC at any time during such U.S. holder’s holding period in Altimar II ordinary shares or warrants. Therefore, U.S. holders of Altimar II ordinary shares that have not made a timely QEF election or a mark-to-market election (as described above) and U.S. holders of Altimar II warrants may, pursuant to the Proposed Regulations, be subject to taxation on the Domestication to the extent their shares and/or warrants have a fair market value in excess of their tax basis. Any such gain would generally be treated as an “excess distribution” made in the year of the Domestication and subject to the special tax and interest charge rules discussed above.

It is difficult to predict whether, in what form and with what effective date, final Treasury Regulations under Section 1291(f) of the Code will be adopted. The rules dealing with PFICs and with the QEF election and purging election (or a mark-to-market election) are very complex and are affected by various factors in addition to those described above. Accordingly, a U.S. holder of Altimar II ordinary shares or warrants should consult its tax advisors concerning the application of the PFIC rules to such securities under such holder’s particular circumstances.

Effect to U.S. Holders of Altimar II Ordinary Shares Exercising Redemption Rights

This section is addressed to U.S. holders of Altimar II ordinary shares (which will be exchanged for Fathom common stock in the Domestication) that elect to exercise Redemption Rights to receive cash in exchange for Altimar II ordinary shares and is subject in its entirety to the discussion of the Domestication, the PFIC rules and Section 367 of the Code as discussed above.

The U.S. federal income tax consequences to a U.S. holder of Altimar II ordinary shares (which become Fathom common stock in the Domestication) that exercises its Redemption Rights to receive cash from the Trust Account in exchange for all or a portion of its common stock will depend on whether the redemption qualifies as

180

a sale of the Fathom common stock redeemed under Section 302 of the Code or is treated as a distribution under Section 301 of the Code. If the redemption qualifies as a sale of such U.S. holder’s Fathom common stock redeemed, the holder will generally recognize capital gain or capital loss equal to the difference, if any, between the amount of cash received and such holder’s tax basis in the Fathom common stock redeemed (which basis will depend on the treatment of the Domestication, including under Section 367 of the Code and the PFIC rules, as described above).

Whether a redemption qualifies for sale treatment will depend largely on the total amount of Fathom common stock treated as held by the U.S. holder (including any shares constructively owned by the U.S. holder as a result of owning warrants) relative to all of Fathom common stock outstanding both before and after the redemption (which will include any Fathom common stock issued under the Stock Issuance Proposal). The redemption of Fathom common stock will generally be treated as a sale of the Fathom common stock (rather than as a corporate distribution) if the redemption (i) is “substantially disproportionate” with respect to the U.S. holder, (ii) results in a “complete termination” of the U.S. holder’s interest in Fathom or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. holder.

In determining whether any of the foregoing tests are satisfied, a U.S. holder takes into account not only Fathom common stock actually owned by the U.S. holder, but also Fathom common stock constructively owned by the U.S. holder. A U.S. holder may constructively own, in addition to shares owned directly, shares owned by certain related individuals and entities in which the U.S. holder has an interest or that have an interest in such U.S. holder, as well as any shares the U.S. holder has a right to acquire by exercise of an option, which would generally include Fathom common stock which could be acquired pursuant to an exercise of any Fathom warrants by such U.S. holder.

In order to meet the substantially disproportionate test, the percentage of the Fathom outstanding voting shares actually and constructively owned by the U.S. holder immediately following the redemption of Fathom common stock must, among other requirements, be less than 80% of the percentage of the Fathom outstanding voting shares actually and constructively owned by the U.S. holder immediately before the redemption. Prior to the Business Combination, the Altimar II ordinary shares and Fathom common stock may not be considered voting shares for this purpose and, consequently, this substantially disproportionate test may not be applicable. There will be a complete termination of such U.S. holder’s interest if either (i) all of the Fathom common stock actually and constructively owned by such U.S. holder are redeemed or (ii) all of the Fathom common stock actually owned by such U.S. holder are redeemed and such U.S. holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of any Fathom common stock actually and constructively owned by certain family members and such U.S. holder does not constructively own any other Fathom common stock and otherwise complies with specific conditions. The redemption of common stock will not be essentially equivalent to a dividend if the redemption results in a “meaningful reduction” of the U.S. holder’s proportionate interest in Fathom. Whether the redemption will result in a meaningful reduction in a U.S. holder’s proportionate interest in Fathom will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a minority stockholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction”.

If the redemption does not qualify as a sale of the Fathom common stock redeemed, the U.S. holder will be treated as receiving a corporate distribution from Fathom. Such distribution will generally be treated as a dividend for U.S. federal income tax purposes to the extent the distribution is paid out of Fathom’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of any such earnings and profits will generally be applied against and reduce the U.S. holder’s basis in its other Fathom common stock (but not below zero) and, to the extent in excess of such basis, will be treated as capital gain from the sale or exchange of such redeemed shares. After the application of these rules, any remaining tax basis of the U.S. holder in such holder’s redeemed Fathom common stock will generally be added to the U.S. Holder’s adjusted tax basis in its remaining Fathom common stock, or, if it has none, to the U.S. Holder’s adjusted tax basis in its Fathom warrants or possibly in other Fathom common stock shares constructively owned by such holder.

181

Because the Domestication will occur immediately prior to the redemption of U.S. holders that exercise Redemption Rights, U.S. holders exercising Redemption Rights will be subject to the potential tax consequences of Section 367 of the Code as a result of the Domestication discussed further above.

U.S. holders who actually or constructively own five percent or more of Fathom stock (by vote or value) may be subject to special reporting requirements with respect to a redemption, and such holders should consult with their tax advisors with respect to any applicable reporting requirements.

All U.S. holders are urged to consult with their tax advisors as to the tax consequences of a redemption of all or a portion of their Fathom common stock pursuant to an exercise of Redemption Rights.

Effect of the Business Combination on U.S. Holders of Fathom Common Stock and Warrants

U.S. holders that hold Fathom common stock and warrants after the Domestication should not recognize gain or loss for U.S. federal income tax purposes solely as a result of the Business Combination.

Non-U.S. Holders

The following describes U.S. federal income tax considerations relating to the ownership and disposition of Fathom common stock and warrants by a non-U.S. holder after the Domestication. A “non-U.S. holder” is a beneficial owner of Fathom common stock or warrants that is, for U.S. federal income tax purposes:

• a non-resident alien individual;

• a foreign corporation; or

• an estate or trust that is not a U.S. holder.

Such term, however, generally does not include an individual who is present in the United States for 183 days or more in the taxable year of disposition. If you are such an individual, you are urged to consult your tax advisor regarding the U.S. federal income tax consequences of the sale or other disposition of Fathom common stock or warrants.

Dividends

Any distribution of cash or property (or a constructive distribution) Fathom makes to a non-U.S. holder of Fathom common stock or warrants, to the extent paid out of Fathom’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles), generally will constitute a dividend for U.S. federal income tax purposes. Any such dividends paid or deemed paid to a non-U.S. holder in respect of Fathom common stock (or warrants) that is not effectively connected with the non-U.S. holder’s conduct of a trade or business within the United States, as described below, generally will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividend, unless such non-U.S. holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate (usually on an IRS Form W-8BEN or W-8BEN-E, as applicable). In satisfying the foregoing withholding obligation with respect to a distribution, the applicable withholding agent may withhold up to 30% of either (i) the gross amount of the entire distribution, even if the amount of the distribution is greater than the amount constituting a dividend, as described above, or (ii) the amount of the distribution Fathom projects will be a dividend, based upon a reasonable estimate of both its current and accumulated earnings and profits for the taxable year in which the distribution is made. If U.S. federal income tax is withheld on the amount of a distribution in excess of the amount constituting a dividend, the non-U.S. holder may obtain a refund of all or a portion of the excess amount withheld by timely filing a claim for refund with the IRS. Any such distribution not constituting a dividend generally will be treated, for U.S. federal income tax purposes, first as reducing the non-U.S. holder’s adjusted tax basis in such Fathom common stock or warrants (but not below zero) and, to the

182

extent such distribution exceeds the non-U.S. holder’s adjusted tax basis, as gain from the sale or other taxable disposition of such Fathom common stock or warrants, which will be treated as described under “— Gain on Sale, Taxable Exchange or Other Taxable Disposition of Fathom Common Stock and Warrants” below.

Dividends (including constructive dividends) Fathom pays to a non-U.S. holder that are effectively connected with such non-U.S. holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base of the non-U.S. holder) generally will not be subject to the foregoing U.S. federal withholding tax, provided such non-U.S. holder complies with certain certification and disclosure requirements (usually by providing an IRS Form W-8ECI). Instead, unless an applicable income tax treaty provides otherwise, such dividends generally will be subject to U.S. federal income tax, net of certain deductions, at the same regular U.S. federal income tax rates applicable to a comparable U.S. holder. In addition, if the non-U.S. holder is a corporation, such holder’s effectively connected earnings and profits (subject to adjustments) may be subject to a U.S. federal “branch profits tax” at a rate of 30% (or such lower rate as may be specified by an applicable income tax treaty).

Gain on Sale, Taxable Exchange or Other Taxable Disposition of Fathom Common Stock and Warrants

A non-U.S. holder generally will not be subject to U.S. federal income tax in respect of gain recognized on a sale, exchange or other disposition of Fathom common stock or warrants unless:

• the gain is effectively connected with the conduct of a trade or business by the non-U.S. holder within the United States (and, if required by an applicable income tax treaty, is attributable to a United States permanent establishment or fixed base of the non-U.S. holder);

• the non-U.S. holder is an individual who is present in the United States for 183 days or more in the taxable year of disposition (subject to certain exceptions as a result of the COVID pandemic) and certain other conditions are met; or

• Fathom is or has been a “United States real property holding corporation” (“USRPHC”) for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the non-U.S. holder’s holding period, and either (i) Fathom’s common stock has ceased to be regularly traded on an established securities market or (ii) the non-U.S. holder has owned or is deemed to have owned under constructive ownership rules, at any time within the five-year period preceding the disposition or the non-U.S. holder’s holding period, whichever period is shorter, more than 5% of Fathom’s Class A common stock.

Unless an applicable tax treaty provides otherwise, any gain described in the first bullet point above generally will be subject to U.S. federal income tax, net of certain deductions, at the same regular U.S. federal income tax rates applicable to a comparable U.S. holder and, in addition, a non-U.S. holder described in the first bullet point that is a foreign corporation will be subject to U.S. federal “branch profits tax” at a 30% rate (or a lower applicable tax treaty rate) on such non-U.S. holder’s effectively connected earnings and profits (subject to adjustments). Any gain of a non-U.S. holder described in the second bullet point above (which may be offset by U.S. source capital losses during the taxable year of the disposition) generally will be subject to a flat 30% U.S. federal income tax rate (or a lower applicable tax treaty rate).

Unless an applicable tax treaty provides otherwise, any gain described in the third bullet point above that is recognized by such non-U.S. holder on the sale, exchange or other disposition of Fathom common stock or warrants generally will be subject to tax at generally applicable U.S. federal income tax rates. In addition, a buyer of such Fathom common stock or warrants from a non-U.S. holder may be required to withhold U.S. income tax at a rate of 15% of the amount realized upon such disposition if such stock or warrants are not treated as “regularly traded on an established securities market.” Fathom will generally be classified as a “U.S. real property holding corporation” if the fair market value of its “United States real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used

183

or held for use in a trade or business, as determined for U.S. federal income tax purposes. Fathom does not expect to be classified as a “U.S. real property holding corporation” following the Business Combination. However, such determination is factual in nature and subject to change, and no assurance can be provided as to whether Fathom is or will be a U.S. real property holding corporation with respect to a non-U.S. holder following the Business Combination or at any future time.

Tax Consequences to Non-U.S. Holders That Elect to Exercise Redemption Rights

This section is addressed to non-U.S. holders of Fathom common stock that elect to exercise Redemption Rights to receive cash in exchange for all or a portion of their Fathom common stock. For purposes of this discussion, a “redeeming non-U.S. holder” is a non-U.S. holder that elects to exercise Redemption Rights in respect of all or a portion of its Fathom common stock.

Because the Domestication will occur immediately prior to the redemption of non-U.S. holders that exercise Redemption Rights with respect to Fathom common stock, the U.S. federal income tax consequences to a redeeming non-U.S. holder will depend on whether the redemption qualifies as a sale of the Fathom common stock redeemed, as described above under “— U.S. Holders — Tax Consequences to U.S. Holders That Elect to Exercise Redemption Rights.” If such a redemption qualifies as a sale of Fathom common stock, the U.S. federal income tax consequences to the redeeming non-U.S. holder generally will be as described above under “— Gain on Sale, Taxable Exchange or Other Taxable Disposition of Fathom Common Stock and Warrants.” If such a redemption does not qualify as a sale of Fathom common stock, the redeeming non-U.S. holder generally will be treated as receiving a distribution, the U.S. federal income tax consequences of which are described above under “— Dividends.”

ALL NON-U.S. HOLDERS ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING THE U.S. FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE DOMESTICATION TO THEM.

Information Reporting and Backup Withholding

Dividend payments with respect to Fathom common stock and proceeds from the sale, exchange or redemption of Fathom common stock or warrants may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status.

A Non-U.S. holder generally will eliminate the requirement for information reporting (other than with respect to dividends) and backup withholding by providing certification of its non-U.S. status on a duly-executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s U.S. federal income tax liability, and a holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Foreign Account Tax Compliance Act

Pursuant to the Foreign Account Tax Compliance Act (“FATCA”), set forth in Sections 1471 through 1474 of the Code, foreign financial institutions (which include hedge funds, private equity funds, mutual funds and any other investment vehicles regardless of their size) must comply with information reporting rules with respect to their U.S. account holders and investors or bear a withholding tax on certain payments made to them (including such payments made to them in their capacity as intermediaries). Generally, if a foreign financial institution or

184

certain other foreign entity does not comply with these reporting requirements, “withholdable payments” to the noncomplying entity will be subject to a 30% withholding tax. For this purpose, withholdable payments include U.S.-source payments otherwise subject to nonresident withholding tax and, subject to the discussion of the proposed Treasury Regulations below, the entire gross proceeds from the sale of certain equity or debt instruments of U.S. issuers. This withholding tax will apply to a non-compliant foreign financial institution regardless of whether the payment would otherwise be exempt from U.S. nonresident withholding tax.

Withholding under FATCA will generally apply to payments of dividends on Fathom common stock to foreign financial institutions that are not in compliance with FATCA. The U.S. Department of the Treasury released proposed regulations which, if finalized in their present form, would eliminate the U.S. federal withholding tax of 30% applicable to the gross proceeds of a sale or disposition of equity interests. In its preamble to the proposed regulations, the U.S. Treasury stated that taxpayers may generally rely on the proposed regulations until final regulations are issued.

Similar withholding requirements to the foregoing apply to dividends on and, subject to the proposed regulations, gross proceeds from the sale of, Fathom common stock held by an investor that is a non-financial foreign entity unless such entity provides certain information regarding the entity’s “substantial United States owners,” which the applicable withholding agent will in turn be required to provide to the Secretary of the Treasury.

If a dividend payment is both subject to withholding under FATCA and subject to the withholding tax discussed above, the withholding under FATCA may be credited against, and therefore reduce, such other withholding tax. Each non-U.S. holder is urged to consult its tax advisor regarding these rules and whether they may be relevant to such non-U.S. holder’s ownership and disposition of Fathom common stock and warrants.

Foreign entities located in jurisdictions that have entered into intergovernmental agreements with the United States in connection with FATCA may be subject to different rules.

186

On July 16, 2021, Altimar Acquisition Corp. II entered into a definitive business combination agreement with Fathom Holdings, LLC, which agreement was amended on November 16, 2021. Notwithstanding the legal form of the business combination pursuant to the Business Combination Agreement, the Business Combination will be accounted for in accordance with ASC Topic 805, Business Combinations (“ASC 805”), using the acquisition method. For accounting purposes, the acquirer is the entity that has obtained control of another entity and, thus, consummated a business combination. The determination of whether control has been obtained begins with the evaluation of whether control should be evaluated based on the variable interest or voting interest model pursuant to ASC Topic 810, Consolidation (“ASC 810”). In all redemption scenarios, Fathom has been determined to be the accounting acquirer based on evaluation of the following factors:

• Fathom OpCo is a variable interest entity (“VIE”). Fathom will be the sole managing member and primary beneficiary which has full and complete charge of all affairs of Fathom OpCo, and the New Fathom Units of Fathom OpCo do not have substantive participating or kick out rights; and

• No single party controls Fathom pre and post transaction, hence, the Business Combination is not considered a common control transaction.

The factors discussed above support the conclusion that Fathom will acquire a controlling financial interest in Fathom OpCo and will be the accounting acquirer. Fathom is the primary beneficiary of Fathom OpCo, which is a VIE, since it has the power to direct the activities of Fathom OpCo that most significantly impact Fathom OpCo’s economic performance through its role as the sole managing member of Fathom OpCo, and Fathom’s variable interests in Fathom OpCo include ownership of Fathom OpCo, which results in the right (and obligation) to receive benefits (and absorb losses) of Fathom OpCo that could potentially be significant to Fathom. Therefore, the Business Combination will be accounted for using the acquisition method. Under this method of accounting, Fathom is treated as the acquirer and Fathom OpCo is treated as the acquired company for financial statement reporting purposes. Upon the consummation of the Business Combination, the assets and liabilities of Fathom OpCo will be recognized at fair value, and any consideration in excess of the fair value of the net assets acquired (including identifiable intangible assets) will be recognized as goodwill.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption into cash of Altimar II’s Public Shares:

• Assuming No Redemptions: This “minimum scenario” presentation assumes that none of the 34,500,000 Public Shares outstanding as of the Record Date are redeemed by Altimar II Public Shareholders.

• Assuming Maximum Redemptions: This “maximum redemptions” presentation assumes that Altimar II’s Public Shareholders redeem 34,500,000 shares of Altimar II’s Class A ordinary shares. This calculation assumes that the full $90 million in aggregate proceeds are received from the PIPE Investment and that the amount in the Trust Account (prior to any redemptions) is equal to $345 million (the approximate amount in the Trust Account as of September 30, 2021), resulting in an aggregate redemption payment (based on an estimated redemption price per share of approximately $10) of $345 million. This scenario results in the following adjustments to the consideration payable at closing:

• Existing Fathom Owner Consideration: A reduction to the amount of the Closing Cash Consideration of $335 million, such that there will be no Closing Cash Consideration (assuming the Balance Sheet contribution is $10 million and the Debt Pay-Down Amount is equal to $20 million), and an increase in the number of shares of Class A common stock and New Fathom Units that comprise the Closing Seller Equity Consideration equal to 33,500,000 (equal to the amount by which Closing Cash Consideration is reduced in this scenario divided by $10), such that the Closing Seller Equity Consideration will be an aggregate number of shares of Class A common stock and New Fathom Units stock equal to 121,293,750.

• Forfeited Shares: Under all scenarios, the Altimar II Founders will forfeit 2,587,500 shares of Class A common stock.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

1. Basis of Presentation

Overview

Under either the no redemption or maximum redemption scenarios, the Business Combination will be accounted for in accordance with ASC 805. For accounting purposes, the acquirer is the entity that has obtained control of another entity and, thus, consummated a business combination. The determination of whether control has been obtained begins with the evaluation of whether control should be evaluated based on the variable interest or voting interest model pursuant to ASC 810. If the acquiree is a variable interest entity, the primary beneficiary would be the accounting acquirer. Fathom OpCo meets the definition of a variable interest entity and Fathom, which will be the managing member, has been determined to be the primary beneficiary. Under this method of accounting, Fathom is treated as the acquirer and Fathom OpCo is treated as the acquired company for financial statement reporting purposes.

The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2021 and the year ended December 31, 2020 gives pro forma effect to the Business Combination as if it had been consummated on January 1, 2020.

The unaudited pro forma condensed combined balance sheet as of September 30, 2021 gives pro forma effect to the Business Combination as if it had been consummated on September 30, 2021.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

The pro forma adjustments reflecting the consummation of the Business Combination are based on certain currently available information and certain assumptions and methodologies that management believes are reasonable under the circumstances. The unaudited condensed combined pro forma adjustments, which are described in the accompanying notes, may be revised as additional information becomes available and is evaluated. Therefore, it is likely that the actual adjustments will differ from the pro forma adjustments and it is possible the difference may be material.

Management believes that its assumptions and methodologies provide a reasonable basis for presenting all of the significant effects of the Business Combination based on information available to management at the time and that the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the unaudited pro forma condensed combined financial information.

The unaudited pro forma condensed combined financial information is not necessarily indicative of what the actual results of operations would have been had the Business Combination taken place on the dates indicated, nor are they indicative of the future consolidated results of operations or financial position of the post-combination company. They should be read in conjunction with the historical financial statements and notes thereto of Fathom OpCo, Altimar II, Incodema, Dahquist, and Majestic Metals included elsewhere in this proxy statement/prospectus.

Description of Business Combination

Altimar Acquisition Corp. II is a blank check company incorporated on December 7, 2020 as a Cayman Islands exempted company organized for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses.

In connection with the Closing:

(a) Altimar II will change its jurisdiction of incorporation by deregistering as an exempted company in the Cayman Islands and continuing and domesticating as a corporation under the laws of the State of Delaware (the “Domestication”), upon which Altimar II will change its name to “Fathom Digital Manufacturing Corporation.”

192

(b) Fathom OpCo will issue managing member interests in Fathom OpCo to Altimar II in exchange for a nominal cash payment;

(c) Following step (b) above, each of CORE Fund I Blocker-5 LLC, a Delaware limited liability company (“Fathom Blocker 1”), CORE Fund I Blocker-2 LLC, a Delaware limited liability company (“Fathom Blocker 2”), and SG (MCT) Blocker, LLC, a Delaware limited liability company (Fathom Blocker 3” and, together with Fathom Blocker 1 and Fathom Blocker 2, the “Fathom Blockers”), will merge with and into Rapid Blocker 1 Merger Sub, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 1”), Rapid Blocker 2 Merger Sub, LLC , a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 2”), and Rapid Blocker 3 Merger Sub, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar II (“Blocker Merger Sub 3” and, together with Blocker Merger Sub 1 and Blocker Merger Sub 2, the “Blocker Merger Subs”), respectively, in each case, with the Fathom Blockers surviving as the surviving companies and wholly owned subsidiaries of Altimar II (collectively, the “Surviving Fathom Blockers”);

(d) Immediately following step (c) above, the Surviving Fathom Blockers will each merge with and into Altimar II (the “Blocker Altimar Mergers”), in each case, with Altimar II as the surviving company; and

(e) Immediately following the Blocker Altimar Mergers, Rapid Merger Sub will merge with and into Fathom OpCo (the “Fathom Merger”), with Fathom OpCo as the surviving entity of the Fathom Merger (Fathom, in its capacity as the surviving entity of the Fathom Merger, is sometimes referred to as the “Fathom Surviving Entity”). Following the Fathom Merger, the Fathom Surviving Entity will be owned by Altimar II and all other holders of Fathom OpCo units outstanding as of immediately prior to the Fathom Merger (such other holders, excluding Altimar II, are referred to as the “Continuing Fathom Unitholders”).

Upon consummation of the transactions contemplated by the Business Combination Agreement, the combined company will be organized in an “Up-C” structure, in which substantially all of the assets and business of the combined company will be held by Fathom OpCo. Altimar II and the Continuing Fathom Unitholders will be issued Class A units of Fathom OpCo (“New Fathom Units”). Altimar II will be the managing member of Fathom OpCo. Altimar II will issue to Continuing Fathom Unitholders for cash at par value a number of shares of Class B common stock equal to the number New Fathom Units held by the Continuing Fathom Unitholders. Altimar II’s other stockholders will hold Class A common stock of Altimar II. Shares of Class A common stock will be entitled to economic rights and one vote per share and shares of Class B common stock will be entitled to one vote per share but no economic rights. The combined company’s business will continue to operate through Fathom OpCo.

Preliminary Purchase Price Allocation

The preliminary consideration and allocation of the purchase price to the fair value of Fathom OpCo’s assets acquired and liabilities assumed, as if the acquisition date was September 30, 2021, is presented below. Fathom has not completed the detailed valuations necessary to estimate the fair value of the assets acquired and the liabilities assumed and, accordingly, the adjustments to record the assets acquired and liabilities assumed at fair value reflect the best estimates of Fathom OpCo based on the information currently available and are subject to change once additional analyses are completed. The final purchase price of the Business Combination is subject to the determination of certain items that are subject to adjustment at Closing pursuant to the Business Combination Agreement.

(2) Refers to the historical results of Incodema, Dahlquist, Majestic Metals, Mark Two, Newchem, GPI, Summit, Centex, Laser, Precision Process, and Micropoulse West prior to their respective acquisitions. Note that each of the Mark Two, GPI, Summit, Centex, Laser, Micropulse West and PPC acquisitions is individually insignificant under S-X Rule 3-05.

a) Cost of revenue

Cost of revenue is impacted by $1.0 million due to increased inventory balances caused by the non-cash impact of the step up to fair value of the inventory.

b) Depreciation and amortization

Adjustments to depreciation and amortization of $9.8 million represent the depreciation and amortization expense related to the step up of the fair value of real property and intangibles assets.

c) Interest Expense

Increase in interest expense of $5.0 million caused by the increase in bank debt incurred to finance the 2021 Acquisitions.

(1) Refers to the historical audited financial statements of Fathom OpCo.

196

(2) Refers to the historical results of Summit, Centex, Laser, Precision Process, and Micropulse West prior to their respective acquisitions.

a) Depreciation and Amortization

Adjustments to depreciation and amortization of $1.1 million represent the depreciation and amortization expense related to the step up of the fair value of real property and intangibles assets.

b) Interest expense/(income)

Adjustments to eliminate interest expense of $8.9 million because the maturity of the loan issued to finance the 2021 Acquisitions is 12 months. Upon the acquisition of Fathom Opco by Fathom, long-term financing will be issued.

4. Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations for the Year Ended December 31, 2020

The unaudited pro forma condensed combined 2020 Income Statement has been prepared to illustrate the effect of the business combination and has been prepared for informational purposes only.

Fathom OpCo and Altimar II have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The following adjustments are incorporated in the unaudited pro forma condensed combined financial information:

a) Cost of Revenue

Cost of revenue is impacted by $5.2 million due to increased inventory balances caused by the non-cash impact of the step up to fair value of the inventory and increased amortization of intangible assets.

b) Selling, general, and administrative

Adjustments to selling, general, and administrative expenses of $41.5 million represent transaction expenses incurred in conjunction with the Business Combination and $1.0 million of stock compensation expenses which will accelerate as a result of the business combination. These adjustments were partially offset by an adjustment of $(0.7) million related to the removal of management fees previously paid.

c) Depreciation and Amortization

Adjustments to depreciation and amortization of $6.2 million represent the depreciation and amortization expense related to the step up of the fair value of real property and intangibles assets.

d) Interest Expense

Adjustments to interest expense represents the increase to interest expense resulting from the incurrence of new debt associated with the closing of the Business Combination of $6.1 million, consisting of cash interest of $5.6 million and the amortization of deferred issuance costs of $0.5 million, which were a result of the Company refinancing its debt in conjunction with the Business Combination, offset by interest expense of $9.3 million related to prior debt which was entered into in order to effectuate the 2020 Acquisitions described in Note 3 to Fathom OpCo’s historical financial statements.

e) Income Taxes

Fathom OpCo has been, and will continue to be, treated as a partnership for U.S. federal and state income tax purposes. As such, Fathom OpCo’s profits and losses will flow through to its partners,

197

including Fathom, and are generally not subject to tax at the Fathom OpCo level. Following the consummation of the Business Combination, Fathom will be subject to U.S. federal, state, and local taxes.

As a result, we expect a portion of our income after our corporate reorganization to be taxable in jurisdictions in which it previously had not been taxable. We expect the blended federal and state tax rate on income attributable to Altimar II to be approximately 26.86% before giving effect to whether or not deferred tax assets are able to be realized by Altimar II. As it is more likely than not that Altimar II’s deferred tax assets will not be realized in accordance with ASC 740, no income tax benefit is recognized.

f) Net (loss) income per share

The net loss per share is calculated using the weighted average shares outstanding, and the issuance of additional Company shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2020. As the Business Combination and related transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable relating to the Business Combination have been outstanding for the entire periods presented. The unaudited pro forma condensed combined financial information has been prepared assuming two alternative levels of redemption by Altimar II’s Public Shareholders of shares of Altimar II’s Class A ordinary shares for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account (calculated based on the amount in the Trust Account as of September 30, 2021).

	Assuming No Redemptions			Assuming Maximum Redemptions
	For the year ended December 31, 2020			For the year ended December 31, 2020

Pro Forma net loss attributable to holders of Class A Common Stock		(31,358	)		(21,460	)
Weighted average shares of Class A Common Stock outstanding — basic and diluted		73,849,425			50,534,508
Net loss per share — basic and diluted	$	(0.42	)	$	(0.42	)

g) Noncontrolling Interest

As described in the section entitled “Proposal No. 1 — The Business Combination Proposal — Structure of the Business Combination,” upon completion of the Business Combination, the Company will control Fathom OpCo as the sole managing member and the Company will be a holding company with no assets or operations other than its equity interest in Fathom OpCo.

Assuming No Redemptions, as a result of the Business Combination, the Company will initially own approximately 54.7% of the economic interest of Fathom OpCo, but will have 100% of the voting power and will control the management of Fathom OpCo. Immediately following the completion of the Business Combination, the non-voting ownership percentage held by the noncontrolling interest will be approximately 45.3%.

Assuming Maximum Redemptions, as a result of the Business Combination, the Company will initially own approximately 37.4% of the economic interest of Fathom OpCo, but will have 100% of the voting power and will control the management of Fathom OpCo. Immediately following the completion of the Business Combination, the non-voting ownership percentage held by the noncontrolling interest will be approximately 62.6%.

198

5. Adjustments to Unaudited Pro Forma Condensed Combined Statement of Operations for the Nine Months Ended September 30, 2021

The unaudited pro forma condensed combined statement of operations for the nine months ended September 30, 2021 has been prepared to illustrate the effects of the business combination and has been prepared for informational purposes only.

Fathom OpCo and Altimar II have not had any historical relationship prior to the Business Combination. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

The following adjustments are incorporated in the unaudited pro forma condensed combined financial information:

a) Cost of Revenue

Cost of revenue is impacted by $1.3 million due to increased inventory balances caused by the non-cash impact of the step up to fair value of the inventory and increased amortization of intangible assets.

b) Selling, general, and administrative

Adjustments to selling, general, and administrative expenses of $1.4 million related to the removal of management fees previously paid.

c) Depreciation and Amortization

Adjustments to depreciation and amortization of $6.4 million represent the depreciation and amortization expense related to the step up of the fair value of real property and intangibles assets.

d) Interest Expense

Adjustments to interest expense represents the decrease to interest expense resulting from the incurrence of new debt associated with the closing of the Business Combination of $4.5 million.

e) Income Taxes

Fathom Opco, LLC has been, and will continue to be, treated as a partnership for U.S. federal and state income tax purposes. As such, Fathom Opco, LLCs profits and losses will flow through to its partners, including Fathom, and are generally not subject to tax at the Fathom Opco, LLC level. Following the consummation of the Business Combination, Fathom will be subject to U.S. federal, state, and local taxes.

As a result, we expect a portion of our income after our corporate reorganization to be taxable in jurisdictions in which it previously had not been taxable. We expect the blended federal and state tax rate on income attributable to Pubco to be approximately 26.86% before given effect to whether or not deferred tax assets are able to be realized by Pubco. As it is more likely than not that Pubco’s deferred tax assets will not be realized in accordance with ASC 740, no income tax benefit is recognized.

f) Net (loss) income per share

The net loss per share is calculated using the weighted average shares outstanding, and the issuance of additional Company shares in connection with the Business Combination, assuming the shares were outstanding since January 1, 2020. As the Business Combination and related transactions are being reflected as if they had occurred at the beginning of the period presented, the calculation of weighted average shares outstanding for basic and diluted net loss per share assumes that the shares issuable relating to the Business Combination have been outstanding for the entire periods presented. The unaudited pro forma condensed combined financial information has been prepared assuming two alternative levels of redemption by Altimar II’s Public

Shareholders of shares of Altimar II’s Class A ordinary shares for cash equal to their pro rata share of the aggregate amount on deposit in the Trust Account (calculated based on the amount in the Trust Account as of September 30, 2021).

Net income per share – basic and diluted	$	(0.05	)	$	(0.07	)

g) Noncontrolling Interest

As described in the section entitled “Proposal No. 1 — The Business Combination Proposal — Structure of the Business Combination,” upon completion of the Business Combination, the Company will control Fathom OpCo as the sole managing member and the Company will be a holding company with no assets or operations other than its equity interest in Fathom OpCo.

Assuming No Redemptions, as a result of the Business Combination, the Company will initially own approximately 54.7% of the economic interest of Fathom OpCo, but will have 100% of the voting power and will control the management of Fathom OpCo. Immediately following the completion of the Business Combination, the non-voting ownership percentage held by the noncontrolling interest will be approximately 45.3%.

Assuming Maximum Redemptions, as a result of the Business Combination, the Company will initially own approximately 37.4% of the economic interest of Fathom OpCo, but will have 100% of the voting power and will control the management of Fathom OpCo. Immediately following the completion of the Business Combination, the non-voting ownership percentage held by the noncontrolling interest will be approximately 62.6%.

6. Adjustments to Unaudited Pro Forma Condensed Combined Balance Sheet as of September 30, 2021

The adjustments included in the unaudited pro forma condensed combined balance sheet as of September 30, 2021 are as follows:

a) Reflects the proceeds of $80.0 million from the issuance of 8,000,000 shares of Class A common stock with a par value of $0.0001 from the PIPE Investment based on estimated commitments received.

b) Reflects the entry into a $125.0 million term loan and a $27.0 million revolver, net of deferred financing fees of $2.4 million, payment of the historical debt of $170.3 million, and payment of accrued interest of $0.9 million.

c) A total of $60.0 million of expected transaction costs are to be incurred with the Business Combination, including $2.4 million of deferred financing costs. Of the total costs, $12.1 million relate to deferred IPO fees described in (f).

d) Reflects the reclassification of $345.0 million of cash and cash equivalents held in the Trust Account of Altimar that will become available for transaction consideration, transaction expenses, and the operating activities in conjunction with the Business Combination.

200

e) Represents the adjustment for the estimated preliminary purchase price allocation for the acquisition of Fathom OpCo resulting from the Business Combination. The preliminary calculation of total consideration is presented above in Note 1 above.

$1,336.4 million and $1,324.8 million has been allocated to goodwill assuming No Redemptions and Maximum Redemptions, respectively. Goodwill represents the excess of the gross consideration over the fair value of the underlying net tangible and identifiable intangible assets acquired. Qualitative factors that contribute to the recognition of goodwill include certain intangible assets that are not recognized as separate identifiable intangible assets. Goodwill represents future economic benefits arising from acquiring Fathom OpCo, primarily due to its strong market position, that are not individually identified and separately recognized as intangible assets. An adjustment of $83.1 million was made to remove Fathom OpCo’s historical goodwill.

In accordance with ASC Topic 350, Goodwill and Other Intangible Assets (“ASC 350”), goodwill will not be amortized, but instead will be tested for impairment at least annually or more frequently if certain indicators are present. In the event that the value of goodwill and/or intangible assets has become impaired, an accounting charge for impairment during the quarter in which the determination is made may be recognized.

This adjustment additionally eliminates the historical accumulated deficit of Fathom OpCo of $22.3 million and establishes additional paid-in-capital of $917.4 million and $684.2 million assuming No Redemptions and Maximum Redemptions, respectively, based upon the value of the business acquired. The additional paid-in capital balance was established by recording the purchase price of $1,454.6 million to the additional paid in capital account. The PIPE Investment of $80.0 million was also recorded to additional paid-in capital. An adjustment of $16.1 million was made to reduce additional paid-in capital for the payment of transaction costs. Adjustments of $318.0 million and $0.0 million were made assuming No Redemptions and Maximum Redemptions, respectively, to reduce additional paid-in capital for the payment cash consideration. Adjustments to increase additional paid-in capital by $335.0 million and $0.0 million were made assuming No Redemptions and Maximum Redemptions, respectively, in order to record the conversion of redeemable share. As discussed below, adjustments of $612.1 million and $845.3 million were made in order to record the non-controlling interest assuming No Redemptions and Maximum Redemptions, respectively. The legacy equity of Fathom OpCo was eliminated through an adjustment of $54.1 million.

Deferred tax assets, additional paid-in capital, and non-controlling interest in the partnership are recognized to reflect the difference between the financial statement and tax basis in the investment in Fathom OpCo, including the deferred tax asset that results from the step-up for tax purposes of certain assets of Fathom OpCo. The realizability of the deferred tax assets is subject to various estimates and assumptions, including preliminary projections of future taxable income.

f) Reflects the payment of deferred IPO fees which includes $12.1 million of deferred underwriters’ and professional fees in connection with Altimar’s IPO.

g) Represents the pro forma adjustments to reclassify Altimar Class B common stock, which will be converted to Altimar Class C common stock as a required step for the Domestication of Altimar and subsequently and immediately converted to Altimar Class A common stock and Altimar redeemable Class A common stock that will be converted to Class A common stock following the Business Combination.

h) Represents the pro forma adjustments to record a non-controlling interest related to the interest held by the Continuing Fathom Unitholders.

As described in the section entitled “Proposal No. 1 — The Business Combination Proposal — Structure of the Business Combination,” upon completion of the Business Combination, the Company will control Fathom OpCo as the sole managing member and the Company will be a holding company with no assets or operations other than its equity interest in Fathom OpCo.

201

The following summarizes the number of shares of Company Class A common stock outstanding upon completion of the Business Combination excluding 9,000,000 Earnout Shares and 1,267,500 Sponsor Earnout Shares:

	Assuming No Redemptions					Assuming Interim Low Redemptions					Assuming Maximum Redemptions
	Shares		Ownership %			Shares		Ownership %			Shares		Ownership %
Altimar II Public Shareholders		34,500,000		46.7	%		17,250,000		27.9	%		—		0.0	%
PIPE Investors		8,000,000		10.8	%		8,000,000		12.9	%		9,000,000		17.8	%
Altimar II Founders		4,770,000		6.5	%		4,770,000		7.7	%		4,770,000		9.4	%
Legacy Fathom Equity Holders		26,579,425		36.0	%		31,801,837		51.4	%		36,764,508		72.8	%
Total Class A Common Shares		73,849,425		100	%		61,821,837		100	%		50,534,508		100	%

i) Represents the impact of the maximum redemption scenario at an estimated per share redemption price. Upon the maximum redemption scenario, $345.0 million in cash will be paid to redeemable shareholders with the offset to additional paid-in capital. In addition, a decrease in cash consideration used in the Business Combination was offset with an increase in equity consideration. In addition, under the maximum redemption scenario, Fathom will own 37.4% of the economic interest of Fathom OpCo, and the Continuing Fathom Unitholders will own the remaining 62.6%, and therefore, this adjustments reflects changes to non-controlling interest as a result of this change.

j) Upon completion of the Business Combination, Fathom will be party to a Tax Receivable Agreement (“TRA”). As described under “Certain Relationships and Related-Party Transactions — Tax Receivable Agreement,” in connection with this Business Combination, Fathom will enter into a TRA with the existing members of Fathom OpCo. The agreement will require the Company to pay to such members (or their owners) 85% of the amount of tax savings, if any, that the Company realizes in certain circumstances as a result of (i) increases in tax basis resulting from the Business Combination, (ii) certain tax attributes of the Fathom OpCo existing prior to the Business Combination, and (iii) tax benefits attributable to payments made under this TRA, generating a liability (the “TRA liability”). The deferred tax asset and the TRA liability for the TRA assume: (A) only exchanges associated with this Business Combination, (B) a share price equal to $10 per share, (C) a constant income tax rate, (D) no material changes in tax law, (E) the ability to utilize tax attributes, (F) no adjustment for potential remedial allocations, and (G) future TRA payments.

Assuming No Redemptions, the TRA has an estimated value of $21.8 million and assuming Maximum Redemptions, the TRA has an estimated value of $4.5 million.

INFORMATION ABOUT ALTIMAR II

General

Altimar II is a blank check company incorporated on December 7, 2020 as a Cayman Islands exempted company organized for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “initial business combination”).

Altimar II’s sponsor, Altimar Sponsor II LLC (the “Sponsor”), is affiliated with HPS Investment Partners, LLC (“HPS”). HPS is a global investment firm with approximately $75 billion of assets under management as of September 30, 2021. Founded in 2007, HPS manages various investment strategies that invest across the capital structure, from privately negotiated senior secured debt and mezzanine investments, asset-based leasing and private equity to syndicated leveraged loans and high yield bonds. HPS is headquartered in New York with 11 additional offices worldwide. As of December 31, 2020, HPS had 152 investment professionals and over 380 employees globally. The scale and breadth of HPS’s platform offers its clients the flexibility to invest in companies large and small, through standard or customized solutions. HPS is led by Chief Executive Officer and Governing Partner Scott Kapnick, who, prior to founding HPS, served as a Management Committee member, Partner and Co-Head of Global Investment Banking at The Goldman Sachs Group, Inc.

Altimar II’s Business Strategy

Building on HPS’s experience in investing in high-quality businesses globally since 2007, Altimar II’s strategy is to acquire a compelling asset with a world class management team that is poised for growth. Altimar II’s goal is to deliver public shareholders an opportunity to own a long term, durable compounding equity investment that can produce strong returns.

Fair Market Value of Target Business

The New York Stock Exchange (the “NYSE”) rules require that the initial business combination must occur with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust) at the time of Altimar II signing a definitive agreement in connection with the initial business combination. Altimar II’s board of directors has determined that this test was met in connection with the proposed business combination at the time the Business Combination Agreement was signed.

Initial Public Offering and Private Placement

On February 9, 2021, Altimar II consummated its initial public offering of 34,500,000 units (the “Units”), which included 4,500,000 units issued pursuant to the full exercise by the underwriters of their over-allotment option. Each Unit consists of one Class A ordinary share, $0.0001 par value per share (the “Class A ordinary shares”), and one-fourth of one redeemable warrant (the “Public Warrants”), each whole Public Warrant entitling the holder thereof to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $345,000,000.

Concurrently with the completion of Altimar II’s initial public offering, the Sponsor entered into a Private Placement Warrants Purchase Agreement, pursuant to which the Sponsor purchased 9,900,000 private placement warrants (the “Private Warrants”), each exercisable to purchase one Class A ordinary share at $11.50 per share, subject to adjustment, at a price of $1.00 per warrant.

205

Effecting the Initial Business Combination

General

Altimar II is not presently engaged in any operations other than to seek an initial business combination. Altimar II intends to effectuate the initial business combination using cash from the proceeds of its initial public offering and the sale of the Private Placement Warrants to the Sponsor, the PIPE Investment described herein and the Closing Seller Equity Consideration.

Shareholder Approval of the Business Combination and Redemption

Pursuant to the terms of the proposed business combination, as described in the section titled “The Extraordinary General Meeting” in this proxy statement/prospectus, Altimar II is seeking shareholder approval at a meeting called for such purpose at which Public Shareholders may seek to redeem all or a portion of their Class A ordinary shares for cash at a price per share equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the proposed business combination, including interest earned on the funds held in the Trust Account and not previously released to Altimar II to pay its income taxes, if any, divided by the number of then-outstanding Class A ordinary shares in accordance with the procedures set forth in this proxy statement/prospectus. The redemption rights require that a beneficial holder must identify itself in order to validly redeem its shares. There will be no redemption rights upon the completion of the proposed business combination with respect to Altimar II’s warrants. Further, Altimar II will not proceed with redeeming its Class A ordinary shares, even if a public shareholder has properly elected to redeem its shares, if the proposed business combination does not close.

The approval of the Business Combination requires an ordinary resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. A majority of the voting power of the issued and outstanding Altimar II Class A ordinary shares and Class B ordinary shares entitled to vote at the Special Meeting must be present, in person or represented by proxy, at the Special Meeting to constitute a quorum and in order to conduct business at the Special Meeting. The holders of the founder shares, who currently own approximately 20% of the issued and outstanding Class A ordinary shares, will count towards this quorum.

Voting Restrictions in Connection with Shareholder Meeting

The Sponsor and each member of Altimar II’s management team have entered into an agreement with Altimar II, pursuant to which they have agreed to waive their redemption rights with respect to any founder shares and public shares held by them in connection with (i) the completion of the proposed business combination, and (ii) a shareholder vote to approve the amendments to Altimar II’s amended and restated memorandum and articles of association (A) that would modify the substance or timing of Altimar II’s obligation to provide holders of its Class A ordinary shares the right to have their shares redeemed in connection with the proposed business combination or to redeem 100% of its public shares if Altimar II does not complete the initial business combination within 24 months from the closing of its initial public offering or during any extension period or (B) with respect to any other provision relating to the rights of holders of Altimar II’s Class A ordinary shares. No consideration was received by the Sponsor or the members of Altimar II’s management team for their waiver of redemption rights.

Liquidation If No Initial Business Combination

Altimar II’s amended and restated memorandum and articles of association provide that it will have only 24 months from the closing of its initial public offering to consummate an initial business combination. If Altimar II has not consummated an initial business combination within 24 months from the closing of its initial public offering, it will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds

206

held in the Trust Account and not previously released to Altimar II to pay its income taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of Altimar II’s remaining shareholders and its board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to Altimar II’s warrants, which will expire and be worthless if Altimar II fails to consummate an initial business combination within 24 months from the closing of its initial public offering. Altimar II’s amended and restated memorandum and articles of association provide that, if it winds up for any other reason prior to the consummation of the initial business combination, Altimar II will follow the foregoing procedures with respect to the liquidation of the Trust Account as promptly as reasonably possible but not more than ten business days thereafter, subject to applicable Cayman Islands law.

The Sponsor and each member of Altimar II’s management team have entered into an agreement with Altimar II, pursuant to which they have agreed to waive their rights to liquidating distributions from the Trust Account with respect to any founder shares they hold if Altimar II fails to consummate an initial business combination within 24 months from the closing of its initial public offering or during any extension period (although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if Altimar II fails to complete the initial business combination within the prescribed time frame).

The Sponsor and Altimar II’s executive officers and directors have agreed, pursuant to a written agreement with Altimar II, that they will not propose any amendment to Altimar II’s amended and restated memorandum and articles of association (A) that would modify the substance or timing of Altimar II’s obligation to provide holders of Altimar II’s Class A ordinary shares the right to have their shares redeemed in connection with the initial business combination or to redeem 100% of Altimar II’s public shares if it does not complete the initial business combination within 24 months from the closing of its initial public offering or (B) with respect to any other provision relating to the rights of holders of Altimar II’s Class A ordinary shares, unless Altimar II provides its public shareholders with the opportunity to redeem their public shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to Altimar II to pay its income taxes, if any, divided by the number of the then-outstanding public shares.

Altimar II expects that all costs and expenses associated with implementing its plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the $1,000,000 held outside the Trust Account plus up to $100,000 of funds from the Trust Account available to Altimar II to pay dissolution expenses, although Altimar II cannot assure you that there will be sufficient funds for such purpose.

If Altimar II were to expend all of the net proceeds of its initial public offering and the sale of the Private Placement Warrants, other than the proceeds deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account, the per-share redemption amount received by shareholders upon Altimar II’s dissolution would be $10.00. The proceeds deposited in the Trust Account could, however, become subject to the claims of Altimar II’s creditors which would have higher priority than the claims of Altimar II’s public shareholders. Altimar II cannot assure you that the actual per-share redemption amount received by shareholders will not be less than $10.00. While Altimar II intends to pay such amounts, if any, Altimar II cannot assure you that it will have funds sufficient to pay or provide for all creditors’ claims.

Although Altimar II will seek to have all vendors, service providers, prospective target businesses and other entities with which it does business execute agreements with it waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of its public shareholders, there is no guarantee that they will execute such agreements or even if they execute such agreements that they would be prevented from bringing claims against the Trust Account including, but not limited, to fraudulent inducement, breach of

207

fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain an advantage with respect to a claim against Altimar II’s assets, including the funds held in the Trust Account. If any third party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, Altimar II’s management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third party that has not executed a waiver if management believes that such third party’s engagement would be significantly more beneficial to Altimar II than any alternative. Examples of possible instances where Altimar II may engage a third party that refuses to execute a waiver include the engagement of a third party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver. Goldman Sachs & Co. LLC and J.P. Morgan Securities LLC, as joint book-running managers in connection with Altimar II’s initial public offering, did not execute an agreement with Altimar II waiving such claims to the monies held in the Trust Account.

In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with Altimar II and will not seek recourse against the Trust Account for any reason. In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to Altimar II if and to the extent any claims by (A) a third party for services rendered or products sold to Altimar II (other than Altimar II’s independent registered public accounting firm), or (B) a prospective target business with which Altimar II has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per public share due to reductions in the value of the trust assets, in each case net of the interest that may be withdrawn to pay Altimar II’s tax obligations, provided that such liability will not apply to any claims by a third party or prospective target business that executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under Altimar II’s indemnity of the underwriters of its initial public offering against certain liabilities, including liabilities under the Securities Act. In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. However, Altimar II has not asked the Sponsor to reserve for such indemnification obligations, nor has Altimar II independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and Altimar II believes that the Sponsor’s only assets are securities of Altimar II. Therefore, Altimar II cannot assure you that the Sponsor would be able to satisfy those obligations. None of Altimar II’s officers or directors will indemnify Altimar II for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per public share due to reductions in the value of the trust assets, in each case, net of the amount of interest which may be withdrawn to pay Altimar II’s income tax obligations, and the Sponsor asserts that it is unable to satisfy its indemnification obligations or that it has no indemnification obligations related to a particular claim, Altimar II’s independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations. While Altimar II currently expects that its independent directors would take legal action on Altimar II’s behalf against the Sponsor to enforce its indemnification obligations to Altimar II, it is possible that Altimar II’s independent directors in exercising their business judgment may choose not to do so in any particular instance. Accordingly, Altimar II cannot assure you that due to claims of creditors the actual value of the per-share redemption price will not be less than $10.00 per public share.

Altimar II will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, prospective target businesses or other entities with which Altimar II does business execute agreements with it waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Sponsor will also not be liable as to any claims

208

under Altimar II’s indemnity of the underwriters of its initial public offering against certain liabilities, including liabilities under the Securities Act. Altimar II has had access to up to $1,000,000 following its initial public offering and the sale of the Private Placement Warrants with which to pay any such potential claims (including costs and expenses incurred in connection with its liquidation, currently estimated to be no more than approximately $100,000). In the event that Altimar II liquidates and it is subsequently determined that the reserve for claims and liabilities is insufficient, shareholders who received funds from Altimar II’s Trust Account could be liable for claims made by creditors, however such liability will not be greater than the amount of funds from the Trust Account received by any such shareholder.

If Altimar II files a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against Altimar II that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy or insolvency law, and may be included in its bankruptcy or insolvency estate and subject to the claims of third parties with priority over the claims of Altimar II’s shareholders. To the extent any bankruptcy or insolvency claims deplete the Trust Account, Altimar II cannot assure you it will be able to return $10.00 per public share to its public shareholders. Additionally, if Altimar II files a bankruptcy or winding-up petition or an involuntary bankruptcy or winding-up petition is filed against it that is not dismissed, any distributions received by shareholders could be viewed under applicable debtor/creditor and/or bankruptcy or insolvency laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy or insolvency court could seek to recover some or all amounts received by Altimar II’s shareholders. Furthermore, Altimar II’s board of directors may be viewed as having breached its fiduciary duty to Altimar II’s creditors and/or may have acted in bad faith, and thereby exposing itself and Altimar II to claims of punitive damages, by paying public shareholders from the Trust Account prior to addressing the claims of creditors. Altimar II cannot assure you that claims will not be brought against Altimar II for these reasons.

Altimar II’s public shareholders will be entitled to receive funds from the Trust Account only (i) in the event of the redemption of Altimar II’s public shares if it does not complete the initial business combination within 24 months from the closing of its initial public offering, (ii) in connection with a shareholder vote to amend Altimar II’s amended and restated memorandum and articles of association (A) to modify the substance or timing of its obligation to provide holders of its Class A ordinary shares the right to have their shares redeemed in connection with the initial business combination or to redeem 100% of its public shares if it does not complete the initial business combination within 24 months from the closing of its initial public offering or (B) with respect to any other provision relating to the rights of holders of Altimar II’s Class A ordinary shares, or (iii) if they redeem their respective shares for cash upon the completion of the initial business combination. Public shareholders who redeem their Class A ordinary shares in connection with a shareholder vote described in clause (ii) in the preceding sentence shall not be entitled to funds from the Trust Account upon the subsequent completion of an initial business combination or liquidation if Altimar II has not consummated an initial business combination within 24 months from the closing of its initial public offering, with respect to such Class A ordinary shares so redeemed. In no other circumstances will a shareholder have any right or interest of any kind to or in the Trust Account. In connection with the proposed business combination, a shareholder’s voting alone will not result in a shareholder’s redeeming its shares to Altimar II for an applicable pro rata share of the Trust Account. Such shareholder must have also exercised its redemption rights described above.

Facilities

Altimar II currently maintains its executive offices at 40 West 57th Street, 33rd Floor, New York, NY 10019. The cost for Altimar II’s use of this space is included in the $10,000 per month fee it will pay to an affiliate of the Sponsor for office space, administrative and support services. Altimar II considers its current office space adequate for its current operations.

Upon consummation of the Business Combination, the principal executive offices of Fathom will be those at 1050 Walnut Ridge Dr., Hartland, Wisconsin 53029, at which time nothing more will be paid to such affiliate of the Sponsor.

209

Employees

Altimar II currently has two executive officers. These individuals are not obligated to devote any specific number of hours to Altimar II’s matters but they intend to devote as much of their time as they deem necessary to Altimar II’s affairs until it has completed the initial business combination. The amount of time they will devote in any time period will vary based on the stage of the business combination process Altimar II is in. Altimar II does not intend to have any full time employees prior to the completion of the initial business combination.

Periodic Reporting and Financial Information

Altimar II’s units, Class A ordinary shares and warrants are registered under the Exchange Act, and Altimar II has reporting obligations, including the requirement that it file annual, quarterly and current reports with the SEC. In accordance with the requirements of the Exchange Act, Altimar II’s annual reports contain financial statements audited and reported on by its independent registered public accountants.

Altimar II will be required to evaluate its internal control procedures for the fiscal year ending December 31, 2022 as required by the Sarbanes-Oxley Act. Only in the event that Altimar II is deemed to be a large accelerated filer or an accelerated filer and no longer qualifies as an emerging growth company, will Altimar II not be required to comply with the independent registered public accounting firm attestation requirement on its internal control over financial reporting.

Altimar II is a Cayman Islands exempted company. Exempted companies are Cayman Islands companies conducting business mainly outside the Cayman Islands and, as such, are exempted from complying with certain provisions of the Cayman Islands Companies Act. As an exempted company, Altimar II has applied for and received a tax exemption undertaking from the Cayman Islands government that, in accordance with Section 6 of the Tax Concessions Act (2018 Revision) of the Cayman Islands, for a period of 20 years from the date of the undertaking, no law which is enacted in the Cayman Islands imposing any tax to be levied on profits, income, gains or appreciations will apply to Altimar II or its operations and, in addition, that no tax to be levied on profits, income, gains or appreciations or which is in the nature of estate duty or inheritance tax will be payable (i) on or in respect of Altimar II’s shares, debentures or other obligations or (ii) by way of the withholding in whole or in part of a payment of dividend or other distribution of income or capital by Altimar II to its shareholders or a payment of principal or interest or other sums due under a debenture or other obligation of Altimar II.

Altimar II is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act. As such, Altimar II is eligible to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not “emerging growth companies” including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in Altimar II’s periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. If some investors find Altimar II’s securities less attractive as a result, there may be a less active trading market for Altimar II’s securities and the prices of its securities may be more volatile.

In addition, Section 107 of the JOBS Act also provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. In other words, an “emerging growth company” can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. Altimar II intends to take advantage of the benefits of this extended transition period.

Altimar II will remain an emerging growth company until the earlier of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of Altimar II’s initial public offering, (b) in which Altimar II

210

has total annual gross revenue of at least $1.07 billion, or (c) in which Altimar II is deemed to be a large accelerated filer, which means the market value of its Class A ordinary shares that are held by non-affiliates exceeds $700 million as of the prior June 30, and (2) the date on which Altimar II has issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

Additionally, Altimar II is a “smaller reporting company” as defined in Item 10(f)(1) of Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. Altimar II will remain a smaller reporting company until the last day of the fiscal year in which (1) the market value of its ordinary shares held by non-affiliates exceeds $250 million as of the prior June 30, or (2) its annual revenues exceeded $100 million during such completed fiscal year and the market value of its ordinary shares held by non-affiliates exceeds $700 million as of the prior June 30.

Legal Proceedings

In connection with the Business Combination, certain purported Altimar II shareholders have sent demand letters, one of which includes a draft complaint, alleging breaches of fiduciary duty and threatening litigation. Altimar II believes that these threatened lawsuits are without merit and, if filed, intends to defend the matters vigorously. Altimar II is currently unable to reasonably determine the outcome of any potential litigation or estimate any potential losses, and, as such, has not recorded a loss contingency. There is no other material litigation, arbitration or governmental proceeding currently pending against Altimar II or any members of its management team in their capacity as such.

Our target market is comprised of the highly fragmented U.S. low- to mid-volume manufacturing market of CNC machining, injection molding, precision sheet metal and additive manufacturing. This market is projected to grow from $25 billion in 2020 to $33 billion in 2025, fueled by growth in demand for additive manufacturing and continuation of the trend of customers increasingly outsourcing their product development prototyping and low- to mid-volume manufacturing needs.

Industry Opportunities

Overall, manufacturing is a very large but highly fragmented market undergoing disruptive changes driven by rapid advances in how products are being designed and manufactured enabled by the adoption of Industry 4.0 practices.

The overall manufacturing market is one of the largest industries in the world, using industrial design processes to turn raw materials into components and finished goods ranging from aircraft to microelectronics. Taking a new product from customer requirements through a design concept, the product development cycle and eventually to manufacture is a complex, costly and time-consuming process. Product development and manufacturing processes are undergoing disruptive changes driven by Industry 4.0 practices, the next wave of the Industrial Revolution.

According to IBIS World, a research firm, there are over 570,000 manufacturing businesses in the US employing over 11.3 million employees. The manufacturing industry is highly fragmented with over 75% of these manufacturing businesses employing less than 20 people, according to a study by SCORE, a research firm. The US Bureau of Labor Statistics reported that there are approximately 2.7 million engineers and technicians with about 75% employed in the manufacturing, professional, scientific, technical, and government sectors.

Within the overall manufacturing market, the highly fragmented low- to mid- volume precision sheet metal fabrication, injection molding, CNC machining, and additive manufacturing market is estimated to be approximately $25 billion.

Shorter product life cycles and demanding customer requirements are changing how companies develop and manufacture new products.

Over the past decade, R&D spending in the manufacturing sector has increased from $445 billion in 2010 to an expected $600+ billion in 2021. Over this period, new products have contributed a growing share of total corporate revenue, requiring an ever-increasing speed and frequency of new product launches. In 2010, 220,000 new products were launched, while in 2021 355,000 new product launches are projected. These trends are

218

pushing companies to innovate faster by accelerating product development cycles to increase their frequency of product launches. Companies must be very agile to be successful.

Product designs are also becoming more complex as companies strive to launch more differentiated and higher functioning products and push manufacturing constraints using increasingly advanced manufacturing processes. As their product portfolio becomes more diverse and customized, companies must manage their manufacturing supply chain to be more localized and on-demand. By digitizing their product lifecycle companies can simplify and consolidate their supply chain.

Deployment of maturing Industry 4.0 practices shortens product time-to-market and provides agility but requires companies to seek out advanced manufacturing partners.

Industry 4.0 is primarily driven by the digitization of manufacturing including the commercialization of additive manufacturing complemented by advanced traditional manufacturing technologies. Advancements in software tools and the use of artificial intelligence/machine learning techniques help to digitize the entire product development and manufacturing lifecycle. The digitization of manufacturing is changing how new products are designed, manufactured and serviced, generating a large need for more on-demand manufacturing at the same time.

Additive manufacturing, complemented by key advanced traditional manufacturing technologies, offers greater agility and flexibility than traditional manufacturing technologies. These technologies are capable of meeting the rigorous demands of corporate customers in the aerospace, automotive, industrial, medical and consumer sectors where products are highly engineered with precise specifications.

On-demand manufacturing technologies allow custom production of parts in low- to mid- volume quantities with condensed turnaround times. As summarized below, these technologies are highly flexible and adaptive:

• Additive manufacturing can produce highly complex parts using printed materials which would otherwise be extremely difficult to produce via traditional methods.

• CNC machining is a subtractive manufacturing process that utilizes a variety of precision computer guided tools. This process yields products with precision and repeatability, while offering high-quality surface finish optionality.

• Injection molding offers the ability to rapidly produce complex parts using molten material, formed in molds. This process delivers consistency, quality, and cost-effectiveness for larger-scale production.

• Precision sheet metal fabrication involves cutting and bending of metal sheets, resulting in parts which are highly durable. Lower production expenses make this a highly attractive fabrication process for low-volume jobs with fewer timing constraints.

Technological advancements are expected to drive continued growth in on-demand digital manufacturing technologies.

• As advances in additive manufacturing make it better suited for higher-volume applications, it is expected to take share from traditional manufacturing processes. Additive manufacturing offers the benefits of speed, part consolidation, weight reduction, and the ability to create complex geometries.

• CNC machining has exhibited rapid technological advances over the past five to ten years and has gained significant share as a result. CNC workflow improvements have streamlined the process, reducing costs.

• While injection molding production serves a mature market, advances in fast-turnaround applications are driving growth which should not be overlooked.

• Precision sheet metal fabrication is projected to grow at an accelerated rate between 2020 and 2025.

219

These technologies have driven significant advancements, improving speed, volumes, material capabilities, and the overall customer experience. Companies leveraging these advanced technologies, particularly the largest and most innovative, are likely to see significant improvements in efficiencies across their entire manufacturing supply chain. In search of further efficiencies, large enterprise companies are regionalizing and shortening their supply chain and consolidating their supplier partners

These same companies are working to take advantage of Industry 4.0 technologies and advancement in the hybridized model of additive manufacturing and advance traditional manufacturing technologies to optimize new product development and manufacturing. Through technological advances, additive manufacturing and other traditional processes are expected to become more accessible, enabling in-house adoption. However, in-house production lines are often underutilized, inefficient, and are not cost effective when used solely for internal needs. In-house manufacturing options often lack the scale and capabilities to deliver end-to-end solutions required by corporate customers.

Within the $25 billion low- to mid- volume market for precision sheet metal fabrication, injection molding, CNC machining, and additive manufacturing, we estimate that approximately 40% is handled in-house, 55%+ is serviced by regional design services bureaus, and the remaining ~5% is captured by legacy digital manufacturers.

There are thousands of small regional design services bureaus nationwide, most of which possess specialized and limited-service offerings. Some of these regional bureaus serve large enterprise companies but are constrained by inability to scale to meet the requirements of these demanding customers along with the scarcity of skilled labor and limited capacity. Legacy on-demand digital manufacturers are focused on prosumers and we believe their focus on automation often compromises the flexibility required to meet the evolving needs of corporate customers. We also believe that these legacy digital manufacturers are best-suited for simple, template-based part production and that their low-touch business model typically is predicated on serving thousands of individual product developers. On-demand digital manufacturing brokers have limited in-house production and must therefore outsource much of their own production needs, limiting oversight of the production process and hindering quality control and the ability to deliver complex parts. Involving multiple manufacturing suppliers also increases customer concerns relating to the safeguarding of intellectual property.

We believe that large enterprise companies, which represent 50-60% of the outsourced portion of this $25 billion low- to mid-volume manufacturing market, are seeking collaborative, long-term partnerships with their key manufacturing suppliers, and in particular a partner that can advance Industry 4.0 practices to scale with them and ultimately allow them to simplify and shorten their supply chain. Fathom OpCo’s value proposition and strategic partnership approach positions the Company to continue taking share from regional design bureaus and legacy digital manufacturers in the $25 billion low- to mid-volume manufacturing market.

We have optimized our platform to streamline the integration of new companies into the Fathom OpCo ecosystem, allowing us to deploy our proprietary playbook and realize synergies.

Sales and Marketing

Our sales and marketing teams are foundational to acquiring new corporate customers and maintaining our existing relationships. Given the multiple purchasing points of contact we regularly encounter within our individual customer accounts, we approach sales relationships through a “land and expand” model. Once we have established an existing relationship, we expand our customer points of contact using our unique digital marketing and commercial strategy within an account by delivering excellent project outcomes, resulting in organic word-of-mouth recommendations within those organizations. This “land and expand” strategy has been an effective model, allowing us to leverage initial customer acquisition costs within these accounts and delivering profitable growth.

We have built a successful enterprise selling team located throughout the US that is focused on acquiring and growing corporate accounts. We also have an internal business development sales team that works to nurture prospect accounts and turn them into customers. Our sales team works closely with our software platform and quoting team to provide our customers the best solution for the outcome they are looking to achieve by leveraging our technology agnostic approach. If customers desire design or manufacturing input, we have a team of sales engineers who have extensive expertise to assist customers in solving for their key project criteria (e.g., budget, performance requirements, timelines, etc.). We offer customers the technologies and experience to deliver within some of the most challenging and complex project constraints.

Our proprietary manufacturing enablement software platform, alongside our commercial strategy, gives us a scalable lever with our unique digital marketing strategy to acquire new customers and contacts within existing customers, which supports our “land and expand” model.

Our automated software platform gives customers access to Fathom OpCo’s comprehensive capabilities and experts enabling an impactful and accelerated solution. We have an industry-leading 30-second injection molding automated quotation solution, as well as instant quoting capabilities for additive manufacturing.

During the twelve months ended March 31, 2021, 91% of our existing customer base utilized our platform to place additional orders, and no one customer accounted for more than 6% of revenue, demonstrating the repeatability and diversification of our customer base. We offer our clients engineering and design support, technical responsiveness, and access to our extensive materials knowledge, while providing superior production speed and quality, in a process tailored to deliver the level of hands-on engagement that suits each customer’s needs.

We operate in a large, fragmented, and competitive industry, competing for customers with a range of digital manufacturers, such as Proto Labs, Inc., digital manufacturing brokers, such as Xometry, and thousands of regional design bureaus. We believe we are uniquely positioned as the only full-service outsourced solution built specifically to cater to the manufacturing needs of enterprise-level corporate customers.

We believe we compare favorably to other industry participants based on the following competitive factors:

• We believe Fathom OpCo owns the widest breadth of advanced manufacturing processes, including additive 2.0 and emerging technologies

• We have a proven track record of serving blue-chip, enterprise-level corporate customers

• Our unified digital customer experience supplemented with embedded engineering driven support teams offer customers unique access to our expertise

• With our twelve manufacturing facilities spread across all U.S. timezones, we offer our clients turnaround times in as little as 24-hours, nationwide

• Fathom OpCo provides one of the industry’s only team of dedicated customer-facing engineers, unlocking the broadest parts envelope and providing customers with high-value customized parts

• We have earned key manufacturing industry certifications which validate our capabilities and precision (tight tolerances, handling of sensitive client data, etc.)

• We possess a wealth of material expertise, technical design capabilities, and engineering resources which we leverage to deliver superior customer results regardless of manufacturing process and production material

Research and Development

Our research and development efforts are focused primarily on software development and the evaluation of new manufacturing technologies and materials to add to the Fathom OpCo digital manufacturing platform, both internally and through our supply chain partners. The digital manufacturing landscape is evolving quickly, with new technologies and materials being brought to market at an increasingly rapid pace. Our research and development, operations and supply chain teams have deep relationships with the leading hardware and materials providers, allowing us to stay current on new technologies coming to market. Our research and development team regularly evaluates opportunities in new technologies and materials across a range of factors including customer demand, technology maturity, and production workflow. Additionally, our research and development team work closely with hardware OEMs and materials providers to ensure production quality and efficiency for our customers.

Intellectual Property

Our ability to drive innovation in the digital manufacturing market depends in part upon our ability to protect our core technology and software know-how. We attempt to protect our intellectual property rights

225

through a combination of patent, trademark and trade secret laws, as well as through contractual provisions and restrictions on access to our proprietary technology which includes both nondisclosure and invention assignment agreements with our consultants and employees and non-disclosure agreements with our vendors and business partners. While unpatented research, development, know-how and engineering skills are important to our business, we pursue patent protection when we believe it is possible and consistent with our overall strategy for safeguarding intellectual property. Our existing patents are expected to expire between March 2034 through August 2038.

As of July 15, 2021, we own two issued United States patents and five pending United States patent applications. Our patents and patent applications are directed to proprietary technology used in data aggregation and analytics for digital manufacturing, systems and methods for producing three-dimensional objects, and printing systems and methods for fabricating injection molds.

As of July 15, 2021, we own five United States trademark registrations, two pending United States trademark applications and one Arizona trademark registration. We have registered “INCODEMA”, “ICOMold”, “SMARTQUOTE”, “FATHOM” and “FATHOM and Design” as trademarks in the United States.

Government Regulations

We are subject to various laws, regulations and permitting requirements of federal, state, and local authorities, including related to environmental and health and safety. We are also subject to various U.S. and foreign laws and regulations related to anti-corruption, embargoes, sanctions, and trade and export controls, including those of the jurisdictions in which we operate, source from, or make sales to. We believe that we are in material compliance with all such laws, regulations, and permitting requirements.

Environmental Matters

We are subject to domestic environmental laws and regulations governing our operations, including, but not limited to, emissions into the air and water and the use, handling, disposal, and remediation of hazardous substances. A certain risk of environmental liability is inherent in our production activities. These laws and regulations govern, among other things, the generation, use, storage, registration, handling, and disposal of chemicals and waste materials, the presence of specified substances in electrical products, the emission and discharge of hazardous materials into the ground, air, or water, the cleanup of contaminated sites, including any contamination that results from spills due to our failure to properly dispose of chemicals and other waste materials, and the health and safety of our employees. We are required to obtain environmental permits from governmental authorities for certain operations.

Facilities

Fathom OpCo’s corporate headquarters are located in Hartland, Wisconsin in a facility that we lease containing approximately 117,000 square feet of office and manufacturing space. We maintain manufacturing facilities in the following locations (square footage amounts are approximate):

• 12,000 square-foot facility leased in Holland, OH

• 20,500 combined square feet across 4 leased facilities leased in Oakland, CA

• 27,000 square-foot facility leased in Ithaca, NY

• 17,500 square-foot facility leased in Newark, NY

• 23,000 square-foot facility leased in Miami Lakes, FL

• 32,000 square-foot facility leased in Tempe, AZ

• 87,000 square-foot facility leased in Denver, CO

226

• 7,500 square-foot facility leased in Pflugerville, TX

• 34,000 square-foot facility leased in Round Rock, TX

• 27,000 square-foot facility owned in McHenry, IL

• 28,000 square-foot facility owned in Ham Lake, MN

• 19,000 square-foot facility owned in Elk Grove, IL

We believe our combined facilities are adequate for our development and production needs in the near future. Should we need to add space or transition into new facilities, we believe we have the ability to expand our footprint on commercially reasonable terms.

Employees

Our employees are the foundation of Fathom OpCo’s enterprise and are essential to maintaining our business model and competitive advantages. As of September 30, 2021, we had 668 employees working across our US locations. Our employees are distributed across functions, including engineering, production, sales, marketing, and general corporate functions. To date, we have not experienced any work stoppages and consider our relationship with our employees to be in good health. None of our employees are subject to a collective bargaining agreement or represented by a labor union.

Our human capital resource objectives include, as applicable, identifying, recruiting, retaining, incentivizing and integrating our existing and additional employees. The principal purpose of our equity incentive plans are to attract, retain and motivate selected employees, consultants and directors through the granting of equity-based compensation awards and cash-based performance bonus awards.

The health and well-being of our employees is critical to our ongoing ability to operate and serve our customers. We are committed to ensuring the safety and well-being of our employees across each location and job function – this includes providing broad benefits to support their health and wellness needs. In order to address the challenges posed by COVID-19, we implemented a number of measures across our locations to ensure maximum protection for our employees and their families, including allowing remote work arrangements where possible. We continue to place the utmost importance on complying with governmental regulations and health authority guidance to ensure that the appropriate steps are taken to protect the well-being of all people engaged with our business.

Legal Proceedings

We are from time to time subject to various claims, lawsuits, and other legal and administrative proceedings arising in the ordinary course of business. Some of these claims, lawsuits, and other proceedings may involve highly complex issues that are subject to substantial uncertainties, and could result in damages, fines, penalties, non-monetary sanctions, or relief. Due to the inherent uncertain nature of litigation, the ultimate outcome or actual cost of settlement may materially vary from estimates.

ALTIMAR II’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL

CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with the financial statements and related notes of Altimar II included elsewhere in this proxy statement/prospectus. This discussion contains forward-looking statements reflecting Altimar II’s current expectations, estimates and assumptions concerning events and financial trends that may affect Altimar II’s future operating results or financial position. Actual results and timing of events may differ materially from those contained in these forward-looking statements due to a number of factors, including those discussed in the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

Overview

We are a blank check company incorporated in the Cayman Islands on December 7, 2020 formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities. We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, our share capital, debt or a combination of cash, share capital and debt.

We expect to continue to incur significant costs in the pursuit of an initial business combination . We cannot assure you that our plans to complete an initial business combination, including the Business Combination with Fathom OpCo, will be successful.

Restatement of Previously Issued Financial Statements

During the preparation of the Company’s unaudited interim condensed financial statements as of September 30, 2021, management determined it should restate its (i) audited balance sheet as of February 9, 2021, filed with the SEC by the Company in a Current Report on Form 8-K on February 16, 2021, (ii) unaudited interim condensed financial statements as of and for the three months ended March 31, 2021 included in the Company’s Quarterly Report on Form 10-Q, filed with the SEC on June 1, 2021, (iii) unaudited interim condensed financial statements as of and for the three and six months ended June 30, 2021 included in the Company’s Quarterly Report on Form 10-Q, filed with the SEC on August 12, 2021, and (iv) unaudited interim condensed financial statements as of and for the three and nine months ended September 30, 2021 included in the Company’s Quarterly Report on Form 10-Q, filed with the SEC on November 10, 2021 (the “Restatement” and the foregoing periods subject to Restatement, the “Affected Periods”). For a discussion of the Restatement and the impact of the Restatement on the unaudited interim condensed financial statements, see Note 1A of Notes to Unaudited Interim Condensed Financial Statements.

Management previously determined the Class A Ordinary Shares subject to possible redemption to be equal to the redemption value of $10.00 per Class A Ordinary Shares while also taking into consideration a redemption cannot result in net tangible assets being less than $5,000,001. Management subsequently determined that the Class A Ordinary Shares issued in connection with the Initial Public Offering can be redeemed or become redeemable subject to the occurrence of future events considered outside the Company’s control. Therefore, management concluded that the redemption value should include all the Class A Ordinary Shares subject to possible redemption, resulting in the Class A Ordinary Shares subject to possible redemption being equal to their redemption value. As a result, management has noted a reclassification adjustment related to temporary equity and permanent equity. This resulted in an adjustment to the initial carrying value of the Class A Ordinary Shares subject to possible redemption with the offset recorded to additional paid-in capital (to the extent available), accumulated deficit and the Class A Ordinary Shares.

In connection with the change in presentation for the Class A Ordinary Shares subject to possible redemption, the Company also restated its earnings per share calculation to allocate net income (loss) pro rata to

228

Class A and Class B Ordinary Shares. The presentation contemplates a Business Combination as the most likely outcome, in which case, both the Class A Ordinary Shares and the Class B Ordinary Shares share pro rata in the income (loss) of the Company.

The Company’s management has concluded that, as a result of the events leading to the Restatement for the Affected Periods described above, a material weakness existed and the Company’s disclosure controls and procedures were not effective for the quarterly period ended September 30, 2021. In light of the material weakness identified and the related Restatement described further in Note 1A to the unaudited interim condensed financial statements, the Company plans to enhance its processes to identify and appropriately apply applicable accounting requirements to better evaluate and understand the nuances of the complex accounting standards that apply to its financial statements. The Company’s plans at this time include providing enhanced access to accounting literature, research materials and documents and increased communication among its personnel and third-party professionals with whom the Company consults regarding complex accounting applications. The elements of its remediation plan can only be accomplished over time, and the Company can offer no assurance that these initiatives will ultimately have the intended effects.

There has been no change in the Company’s total assets, liabilities or operating results.

For more information regarding the Restatement for the Affected Periods, see Note 1A to the unaudited interim condensed financial statements.

Results of Operations

We have neither engaged in any operations nor generated any revenues through September 30, 2021. All activity for the period from December 7, 2020 (inception) through September 30, 2021 were organizational activities, those necessary to prepare for the Initial Public Offering as described below and, subsequent to the closing of the Initial Public Offering, identifying a target company for a Business Combination, and activities in connection with the proposed business combination with Fathom Holdco, LLC. We do not expect to generate any operating revenues until after the completion of our Business Combination. We generate non-operating income in the form of interest income on investments held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended September 30, 2021, we had a net income of $2,602,517, which consists of the decrease in the fair value of warrant liability of $3,718,348, operating costs of $1,121,132, and interest income on investments held in the Trust Account of $5,301.

For the nine months ended September 30, 2021, we had a net income of $755,552, which consists of operating costs of $1,691,620 and transaction costs allocated to the Warrants of $755,071, offset by a decrease in the fair value of warrant liability of $3,190,546 and interest income on investments held in the Trust Account of $11,697.

Liquidity and Capital Resources

On February 9, 2021, we consummated the Initial Public Offering of 34,500,000 Units at $10.00 per Unit, generating gross proceeds of $345,000,000 as described in Note 3 to the condensed financial statements. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 9,900,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant in a private placement transaction to the Sponsor, generating gross proceeds of $9,900,000 as described in Note 4 to the condensed financial statements.

Following the Initial Public Offering, the full exercise of the over-allotment option and the sale of the Private Placement Warrants, a total of $345,000,000 was placed in the Trust Account. We incurred $19,490,958 in costs related to the Initial Public Offering, consisting of $6,900,000 of underwriting fees, $12,075,000 of deferred underwriting fees and $515,958 of other offering costs.

229

For the nine months ended September 30, 2021, cash used in operating activities was $2,176,537. Net income of $755,552 was affected by a decrease in the fair value of warrant liability of $(755,071), transaction costs allocated to the Warrants of $(3,190,546) and interest earned on investments held in the Trust Account of $11,697. Changes in operating assets and liabilities used $484,917 of cash for operating activities.

As of September 30, 2021, we had investments held in the Trust Account of $345,011,697 (including $11,697 of interest income) consisting of money market funds, which are invested primarily in U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of September 30, 2021, we had cash of $331,112 held outside of the Trust Account. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or an affiliate of the Sponsor, or certain of the Company’s executive officers and directors may, but are not obligated to, loan the Company funds as may be required. If we complete a Business Combination, we would repay such Working Capital Loans. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such Working Capital Loans but no proceeds from the Trust Account would be used for such repayment. Up to $2,000,000 of such Working Capital Loans may be convertible into warrants at a price of $1.00 per warrant, at the option of the lender. The warrants would be identical to the Private Placement Warrant.

We do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business. However, if our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination is less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our Business Combination. Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of the Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.

Off-Balance Sheet Arrangements

We had no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2021. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities or purchased any non-financial assets.

Contractual Obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay an affiliate of the Sponsor a sum of $10,000 per month for office space and secretarial and administrative services. We began incurring these fees on February 4, 2021 and will continue to incur these fees monthly until the earlier of the completion of the Business Combination and our liquidation.

230

The underwriters are entitled to a deferred underwriting fee of $0.35 per Unit, or $12,075,000 in the aggregate. The deferred underwriting fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Critical Accounting Policies

The preparation of condensed financial statements and related disclosures in conformity with GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. We have identified the critical accounting policies set forth below.

Warrant Liability

We account for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the Warrants’ specific terms and applicable authoritative guidance in the FASB ASC Topic 480, “Distinguishing Liabilities from Equity,” and ASC Topic 815, “Derivatives and Hedging.” The assessment considers whether the Warrants are freestanding financial instruments pursuant to ASC Topic 480, whether Warrants meet the definition of a liability pursuant to ASC Topic 480 and whether the Warrants meet all of the requirements for equity classification under ASC Topic 815, including whether the Warrants are indexed to the Class A Ordinary Shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of issuance of the Warrants and as of each subsequent quarterly period end date while the Warrants are outstanding.

For issued or modified Warrants that meet all of the criteria for equity classification, the Warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified Warrants that do not meet all the criteria for equity classification, the Warrants are required to be recorded at their initial fair value on the date of issuance and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The fair value of the Public Warrants was determined using the closing price of the Public Warrants, and the fair value of the Private Placement Warrants was estimated using a Monte Carlo simulation approach.

Class A Ordinary Shares Subject to Possible Redemption

We account for the Class A Ordinary Shares subject to possible redemption in accordance with the guidance in ASC Topic 480, “Distinguishing Liabilities from Equity.” Class A Ordinary Shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable Class A Ordinary Shares (including Class A Ordinary Shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A Ordinary Shares are classified as shareholders’ equity. The Class A Ordinary Shares feature certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, the Class A Ordinary Shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ equity section of our condensed balance sheets.

Net Income (Loss) Per Ordinary Share

The Company has two classes of ordinary shares, which are referred to as Class A Ordinary Shares and Class B Ordinary Shares. Income and losses are shared pro rata between the two classes of ordinary shares. Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding for the period. The calculation of diluted income (loss) per share does not consider the effect of the Public Warrants issued in connection with the Initial Public Offering and the sale of the Private Placement Warrants, because the exercise of the warrants is contingent upon the occurrence of future events.

231

Recent Accounting Standards

In August 2020, the FASB issued Accounting Standards Update No. 2020-06, “Debt—Debt with Conversion and Other Options (Subtopic 470-20)” and “Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity,” which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. We adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on our condensed financial statements.

Our management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our condensed financial statements.

FATHOM OPCO’s MANAGEMENT’S DISCUSSION AND ANALYSIS OF

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with Fathom OpCo’s financial statements and notes thereto included elsewhere in this filing on Form 8-K. This discussion and analysis contains forward-looking statements that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward- looking statements as a result of various factors, including those set forth elsewhere in this proxy statement/prospectus.

Overview

Fathom Holdco, LLC (“Fathom OpCo”) was formed in Delaware in 2021. However, our roots stretch back over 35 years with the founding of several of our subsidiaries. The terms “Fathom OpCo,” the “Company,” “we,” “us,” and “our” as used herein refer to the business and operations of Fathom OpCo and its subsidiaries.

We are a leading national on-demand digital manufacturing platform at the forefront of the Industry 4.0 revolution. Industry 4.0 utilizes e-commerce, automation, and data sharing in a cyber-physical system to communicate and cooperate in the manufacturing process over the Internet of Things (IoT). Using our expansive manufacturing footprint and extensive expertise in both additive and traditional manufacturing, we provide comprehensive product development and on-demand manufacturing services to many of the largest and most innovative companies in the world. Our unified suite of manufacturing technologies, processes, and proprietary software enables us to deliver hybridized solutions that meet the specific needs of our customers, empowering them to tackle complex manufacturing problems and accelerate product development cycles.

Our differentiated strategy focuses on speed, problem solving, adaptive technical responsiveness, and manufacturing to meet customers’ design intent, which allows our customers to iterate faster, often shortening their product development and production cycles from months to days.

We seamlessly blend in-house capabilities consisting of plastic and metal additive technologies, injection molding and tooling, computer numerical control (“CNC”) machining, and precision sheet metal fabrication. We operate over 530 advanced manufacturing systems across 25 unique manufacturing processes and a 450,000 sq. ft. manufacturing footprint, spanning 12 facilities located primarily within the United States. We believe we are positioned to serve the largest geographic markets in which our customers are located and enable cost effective and rapid turnaround times for our customers. Our scale and the breadth of offerings allow our customers to consolidate their supply chain and product development needs through the ability to source through a single manufacturing supplier. Fathom’s manufacturing technologies and capacity are further extended through the utilization of a selected group of highly qualified suppliers that specialize in injection molding and tooling and CNC machining.

We have experienced significant growth since inception both organically and through our successful and proven acquisition playbook, which is enabled by our proprietary software platform that allows for a streamlined integration of acquired companies. Over the past three years, we have successfully completed 13 acquisitions to bolster our operations and offerings. Fathom started as Midwest Composite Technologies, LLC (“MCT”), a leader in prototyping and low-volume services. Founded in 1984, MCT specialized in model making, industrial design, and rapid prototyping. Today, MCT serves companies through a variety of in-house additive manufacturing technologies, including 3D printing and processing, CNC machining, injection molding, and industrial design capabilities. In September 2019, we acquired Kemeera, LLC d/b/a FATHOM (“FATHOM”) to expand our additive, CNC machining injection molding, and development and engineering services, as well as bring urethane casting capabilities. In December 2019, we acquired ICOMold, LLC (“ICOMold”) to expand our injection molding capabilities and significantly enhance our customer experience by bringing in-house an interactive, automated quotation system capable of providing feedback in 30 seconds with an intuitive, customer-

233

facing project management portal, which we have continued to develop and enhance. Our acquisition of ICOMold also expanded our capabilities into China. In July 2020, we acquired Incodema, LLC (“Incodema”) and Newchem, LLC (“Newchem”) to expand our in-house manufacturing processes to include precision sheet metal engineering solutions, including a broad array of sheet metal cutting and forming solutions such as laser cutting, micro waterjet, specialty stamping, and photochemical etching, among others, for quick and complex, tight tolerance parts. In August 2020, we acquired GPI Prototype & Manufacturing Services, LLC (“GPI”) to expand our additive manufacturing capabilities. GPI was one of the first metal additive manufacturing service providers in the United States, bringing metallurgical expertise in-house and enabling the Company to produce metal parts with complex geometries for on-demand manufacturing applications. In December 2020, we acquired Dahlquist Machine, LLC (“Dahlquist”) to expand our precision machining capabilities with state-of-the-art CNC mills and lathes for high-speed precision machining of light metals, aluminum, and plastics. In December 2020, we also acquired Majestic Metals, LLC, (“Majestic Metals”) further expanding our precision sheet metal fabrication capabilities. Further, in December 2020, we acquired Mark Two Engineering, LLC (“Mark Two”) expanding our precision machining services and footprint in the medical device industry. In February 2021, we acquired Summit Tooling, Inc. and Summit Plastics LLC, (collectively, “Summit”) further expanding our plastic injection mold manufacturing capabilities. In April 2021, we acquired Centex Machine and Welding Inc. (“Centex”) and Laser Manufacturing, Inc. “(Laser) to expand our high-precision manufacturing services specializing in CNC Machining and medical device manufacturing. In April 2021, we also acquired Sureshot Precision LLC d/b/a Micropulse West (“Micropulse West”) expanding our Electrical Discharge Machine (“EDM”) services, and CNC and manual machining capabilities. Further, in April 2021, we acquired Precision Process LLC specializing in CNC machining, engineering support, and EDM services.

We continue to invest significantly in the enhancement and expansion of our technologies, processes, and capabilities with the aim of better serving the needs of a broader set of customers and end-markets. As a result of our efforts described above, we have developed a loyal base of approximately 3,000 customers, including many of the most innovative companies in the world. Our customers span across a diverse range of end-markets, including, but not limited to, the aerospace, defense, technology, medical, automotive, and IoT sectors. This diverse customer base has allowed for no single customer to represent more than 4.0% and 6.4% of our revenue in 2020 and 2019, respectively, and 5.4% and 4.7% of our revenue for the nine months ended September 30, 2021 and 2020, respectively. Our overall customer retention rate is 91%, with retained customers representing 86% and 88% of our revenue in 2020 and 2019, respectively, and 88% and 87% of our revenue for the nine months ended September 30, 2021 and 2020, respectively.

We believe the market for our on-demand digital manufacturing services across manufacturing applications is largely unsaturated as companies continue to realize the efficiency and effectiveness of our rapid quotation system and 3D CAD driven manufacturing processes. Our market is projected to grow from $25 billion in 2020 to $33 billion in 2025, fueled by growth in demand for additive manufacturing and continuation of the trend of customers increasingly outsourcing their prototyping and low-to-medium volume production needs. We believe our position as the only on-demand digital manufacturing platform purpose-built to serve the rapid prototyping and low-to-medium volume production needs of the largest and most innovative companies, coupled with our competitive strengths, will allow us to maintain and extend our market leading position.

Our revenues were $61.3 million and $20.6 million for the years ended December 31, 2020 and 2019, respectively, and $107.9 million and $42.2 million for the nine months ended September 30, 2021 and 2020, respectively. Our operating expenses were $27.0 million and $10.1 million for the years ended December 31, 2020 and 2019, respectively, and $38.8 and $16.3 million for the nine months ended September 30, 2021 and 2020, respectively. Our recent growth in revenue has been accompanied by increased cost of revenue and operating expenses. We expect to increase investment in our operations to support anticipated future growth as discussed more fully below.

Going Concern

On April 30, 2021, the Company completed a financing transaction whereby it issued a $172 million term loan due April 2022 (the “2021 Term Loan”) in order to finance the acquisitions of Centex Machine and

Welding, Inc. (“Centex”), Laser Manufacturing, Inc. (“Laser”), Sureshot Precision, LLC d/b/a Micropulse West (“Micropulse West”), and Precision Process Corporation (“PPC”), as well as to refinance the Company’s existing debt, as described in Note 8 — Long-Term Debt in the accompanying Notes to the audited Consolidated Financial Statements. See Note 8 — Debt in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information regarding the April 30, 2021 financing transaction.

As the Company does not have sufficient cash on hand and cash flow from operations to repay the 2021 Term Loan, the maturity of the 2021 Term Loan raises substantial doubt about our ability to continue as a going concern within the next twelve months. If we are unable to repay, refinance or restructure our 2021 Term Loan, our assets may not be sufficient to repay in full the amounts owed.

To address the upcoming maturity of the 2021 Term Loan, the Company has entered into a new credit facility with its existing creditors (the “New Credit Agreement”). The New Credit Agreement includes a $50 million revolving credit facility and $125 million term loan, and matures in 2026. The proceeds from these loans will be used to repay the 2021 Term Loan. Upon the closing of the Business Combination, which is expected to satisfy the requirements of a SPAC Transaction (as defined below), the Company intends to use proceeds from borrowings under the New Credit Agreement to repay in full the 2021 Term Loan.

The funding of the New Credit Agreement is contingent on the Company closing a definitive business combination with a publicly traded Special Purpose Acquisition Company (“SPAC”) before April 9, 2022 (the “SPAC Transaction”). In addition, the cash proceeds of such SPAC Transaction must be at least $313 million, or a lesser amount if mutually agreed by the Company and the SPAC. If the SPAC Transaction is not completed prior to April 9, 2022, the Company will not receive any funds nor incur any indebtedness from the New Credit Agreement. Given the SPAC Transaction will be subject to regulatory and market conditions, as well as approval by a SPAC’s shareholders, and the SPAC securing adequate financing, it is not within the Company’s control and therefore cannot be deemed probable. As a result, the Company has concluded that management’s plans described above do not alleviate substantial doubt about the Company’s ability to continue as a going concern for the next twelve months.

The accompanying financial statements of Fathom OpCo do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the financial statements have been prepared on a basis that assumes that Fathom OpCo will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Key Factors Affecting Our Results

Our financial position and results of operations depend to a significant extent on the following actors:

Industry Opportunity and Competitive Landscape

As discussed above, the market in which we operate is projected to grow from $25 billion in 2020 to $33 billion in 2025, fueled by growth in demand for additive manufacturing and continuing trends in customer outsourcing of production needs. We operate in a large, fragmented, and competitive industry, competing for customers with a range of digital manufacturers, digital manufacturing brokers, and regional design bureaus. We believe we are uniquely positioned as the only full-service outsourced solution built specifically to cater to the manufacturing needs of enterprise-level corporate customers. In particular, we believe we compare favorably to other industry participants on the basis of the following competitive factors:

• Fathom OpCo owns a wide breadth of advanced manufacturing processes, including additive 2.0 and emerging technologies

• We have a proven track record of serving blue-chip, enterprise-level corporate customers

235

• We offer our clients turnaround times in as little as 24-hours, nationwide

• Our unified digital customer experience supplemented by with embedded support teams

• Fathom OpCo provides the industry’s only team of dedicated customer-facing engineers, unlocking the broadest parts envelope and providing customers with high-value customized parts

• Our list of certifications validates our capabilities and precision (tight tolerances, handling of sensitive client data, etc.)

• We possess a wealth of material expertise, technical design capabilities, and engineering resources which we leverage to deliver superior customer results regardless of manufacturing process and production material

• Our successful and proven acquisition integration playbook for strategic growth opportunities

Customer Product Life Cycle and Connectivity

We believe that a number of trends affecting our industry have affected our results of operations and may continue to do so. For example, we believe that many of our target customers are facing three mega trends which are disrupting long-term product growth models including (i) increased pressure to shorten product life-cycles, (ii) manufactured parts on-demand, and (iii) expectation to deliver products that are personalized and customized to unique customer specifications. We believe we continue to be well positioned to benefit from these trends given our proprietary technology alignment with Industry 4.0 trends that enables us to automate and integrate processes involved in manufacturing custom parts. The COVID-19 pandemic has also impacted the manufacturing environment. For example, the pandemic accelerated the digitization of manufacturing as companies pivoted to a work-from-home and socially-distanced manufacturing plant environment. As a result, the adoption of e-commerce was accelerated, which allows opportunity for us to provide valuable solutions to manufacturers looking to build resiliency in their supply chains through fast, on-demand manufacturers. While our business may be positively affected by these trends, our results may also be favorably or unfavorably impacted by other trends that affect product developer and engineer orders for custom parts in low volumes, including, among others, economic conditions, changes in product developer and engineer preferences or needs, developments in our industry and among our competitors, and developments in our customers’ industries. For a more complete discussion of the risks facing our business, see “Risk Factors” in this proxy statement/prospectus.

Manufacturing Facilities and Capacity

We believe our combined facilities are adequate for our development and production needs in the near future. Should we need to add space or transition into new facilities, we believe we have the ability to expand our footprint on commercially reasonable terms.

Impacts of the COVID-19 pandemic

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus as a “pandemic.” First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the Consolidated Financial Statements and Interim Consolidated Financial Statements, our operations have not been significantly impacted, but we continue to monitor the situation. No impairments were recorded as of the interim consolidated balance sheet date, as no triggering events or changes in circumstances had occurred during fiscal 2021 through the issuance of the interim consolidated condensed financial statements; however, due to uncertainty surrounding the situation, and specifically as it pertains to the current global supply chain disruptions, management’s judgment regarding this could change in the future. In addition, while our results of operations, cash flows and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time. The health and well-being of our employees is critical to our ongoing ability to operate and serve our customers. We are committed to ensuring the safety and well-being of our employees across each location and job function,

236

which includes providing broad benefits to support their health and wellness needs. In order to address the challenges posed by COVID-19, we implemented a number of measures across our locations to ensure maximum protection for our employees and their families, including allowing remote work arrangements where possible. We continue to place the utmost importance on complying with governmental regulations and health authority guidance to ensure that the appropriate steps are taken to protect the well-being of all people engaged with our business.

Non-GAAP Information

This proxy statement/prospectus includes Adjusted EBITDA and Pro Forma Adjusted EBITDA, which are non-GAAP performance measures that we use to supplement our results presented in accordance with U.S. GAAP. We believe Adjusted EBITDA and Pro Forma Adjusted EBITDA are useful in evaluating our operating performance, as they are similar to measures reported by our public competitors and are regularly used by security analysts, institutional investors and other interested parties in analyzing operating performance and prospects. Adjusted EBITDA and Pro Forma Adjusted EBITDA are not intended to be substitutes for any U.S. GAAP financial measure and, as calculated, may not be comparable to other similarly titled measures of performance of other companies in other industries or within the same industry.

During 2019 and 2020 we completed the acquisitions of FATHOM, ICO Mold, Incodema, Newchem, GPI, Dahlquist, Majestic Metals, and Mark Two, (the “Prior Acquisitions”) as discussed in further detail in Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements. During 2021 we completed the acquisitions of Summit, Centex, Laser, Micropulse West and PPC (the “2021 Acquisitions”) as discussed in further detail in Note 3 – Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements.

We define and calculate Adjusted EBITDA as net losses before the impact of interest income or expense, income tax expense and depreciation and amortization, and further adjusted for the following items: stock-based compensation, transaction-related costs, and certain other non-cash and non-core items, as described in the reconciliation below. We define and calculate Pro Forma Adjusted EBITDA as pro forma net loss before the impact of interest income or expense, income tax expense or benefit and depreciation and amortization, and further adjusted for the same items as Adjusted EBITDA.

We include these non-GAAP financial measures because they are used by management to evaluate Fathom’s OpCo’s core operating performance and trends and to make strategic decisions regarding the allocation of capital and new investments. Adjusted EBITDA excludes certain expenses that are required in accordance with U.S. GAAP because they are non-recurring (for example, in the case of transaction-related costs), non-cash (for example, in the case of depreciation and amortization, stock-based compensation) or are not related to our underlying business performance (for example, in the case of interest income and expense). Pro Forma Adjusted EBITDA excludes the same categories of expenses and is prepared for the nine months ended September 30, 2021, the nine months ended September 30, 2020, and the year ended December 31, 2020 to give pro forma effect to the Prior Acquisitions and 2021 Acquisitions as if they had occurred on January 1, 2020, and for the year ended December 31, 2019, to give pro forma effect to the Prior Acquisitions as if they had occurred on January 1, 2019.

Pro Forma Adjusted EBITDA

The table below presents our Non-GAAP Pro Forma Adjusted EBITDA reconciled to pro forma net income (loss), the closest U.S. GAAP measure, for the periods indicated.

Pro forma net income (loss) for the nine months ended September 30, 2021 and year ended December 31, 2020 is based on Fathom OpCo’s pro forma financial information found in the Notes to Unaudited Pro Forma Condensed Combined Financial Information set forth in the section titled “Unaudited Pro Forma Condensed Combined Financial Information.”

Pro forma net income (loss) for the nine months ended September 30, 2020 and for the year ended December 31, 2019 is based on pro forma financial information found within this section titled “Fathom OpCo’s Management’s Discussion and Analysis of Financial Condition and Results of Operations”.

Due to differences in pro forma assumptions, the information presented for the years ended December 31, 2020 and 2019 are not comparable. Notably, pro forma information for 2020 gives effect to the 2021 Acquisitions as though such transactions occurred on January 1, 2020 while the pro forma information for 2019 does not give effect to the 2021 Acquisitions.

Key Financial Measures and Trends

Revenue

Our operations are comprised of one operating segment in the United States, with limited operations in China. Revenue is derived from our additive manufacturing, injection molding, CNC machining, and sheet metal product lines. Additive manufacturing revenue consists of sales of custom 3D-printed parts. Injection molding revenue consists of sales of custom tooling and injection molded parts. CNC machining revenue consists of sales of CNC-machined custom parts. Precision sheet metal revenue consists of sales of fabricated sheet metal custom parts. Other product lines include, but are not limited to, urethane casting as well as in-house assistance, industrial design, and engineering services. Our revenue is generated from a diverse customer base, with no single customer representing more than 4.0% and 6.4% of our revenue in 2020 and 2019, respectively, and 5.4% of our revenue for the nine months ended September 30, 2021. Our historical and current efforts to increase revenue have been directed at gaining new customers and selling to our existing customer base by increasing marketing and selling activities, including:

• Capitalizing on outsourcing trends in prototyping and low-to-medium volume manufacturing

• Increased penetration of our existing customer base and expansion through new enterprise-level corporate customers

• Further expansion of our “land and expand” customer relationship model

• Expanded offering of additive manufacturing services

• Further expansion of our software and digital capabilities

• Promotion of customer supply chain consolidation synergies with quality and rapid turnaround times

• Completion of eight strategic acquisitions to expand capabilities and expertise, add scale, and increase our customer-base

• Continued pursuit of strategic acquisitions

The economic uncertainty arising from the COVID-19 pandemic has impacted the number of customers who purchase our products. However, our acquisition-related activities have offset such impact and we expect the number of customers served to grow in the long-term despite the challenges posed by the COVID-19 pandemic on the global economy. Although steps taken by national and local governments to slow the spread of the virus, including business shutdowns and shelter in place orders, hindered our customer’s ability to proceed with some development and commercialization projects on the same scale as they have historically, we are seeing significant improvements in the marketplace as vaccination and reopening efforts take effect. We believe some of the Industry 4.0 trends, including opportunities from reshoring and our supply chain management services, will further offset and limit the impacts of the COVID-19 pandemic going forward.

Cost of Revenue, Gross Profit and Gross Margin

Cost of revenue consists primarily of raw materials, equipment depreciation, employee compensation including benefits, facilities costs and overhead allocations associated with the manufacturing process for molds, tools, and custom parts. We expect our personnel-related costs to increase in order to retain and attract top talent and remain competitive in the market. Overall, we expect cost of revenue to increase in absolute dollars, but remain relatively constant as a percentage of total revenue.

239

Our business model requires that we invest in our manufacturing capacity well in advance of demand to ensure we can meet customer expectations for quick delivery of our products. Therefore, during each of period presented, we have made significant investments in equipment and infrastructure as well as software development and IT. As we expect to continue to grow in future periods, we anticipate the need for additional investments in equipment and software development. However, we believe that these additional costs will be offset by increased revenue growth, economies of scale, and a migration to a multiple-shift manufacturing system, which will maximize plant utilization and help realize operating efficiencies, allowing us to improve our margins over time.

We define gross profit as our revenue less our cost of revenue, and we define gross margin as gross profit expressed as a percentage of revenue. Our gross profit and gross margin are affected by many factors, including our mix of revenue by product line, pricing, sales volume, manufacturing costs, the costs associated with increasing production capacity, the mix between domestic and foreign revenue sources and foreign exchange rates.

Operating Expenses

Operating expenses consist of selling, general, and administrative expenses, which consists primarily of employee compensation, benefits, stock-based compensation, professional service fees related to accounting, tax and legal and other related overhead as well as depreciation and amortization related to the declining residual value of our tangible and intangible assets. Our recent growth in selling, general and administrative expenses is mainly due to higher headcounts and transaction costs to support our growth and expansion, and we expect that trend to continue. Our business strategy is to continue to build a leading digital manufacturing platform aligned with Industry 4.0 trends, utilizing e-commerce, automation, and data sharing in smart factories to produce quick- turn, on-demand custom parts. In order to achieve our goals, we anticipate continued substantial investments in technology and personnel, resulting in increased operating expenses. We expect our operating expenses to increase on an absolute basis and as a percentage of revenue as we continue to grow and expand our operations and develop the infrastructure necessary to operate as a public company. These expenses will include increased audit and legal fees, costs of compliance with securities and other regulations, implementation costs for compliance with the provisions of the Sarbanes-Oxley Act, investor relations expense and higher insurance premiums.

Our recent increase in depreciation and amortization expenses is mainly due to our continued acquisition strategy to support our growth and expansion, and we expect that trend to continue as well. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the individual assets. Leasehold improvements are amortized over the shorter of the useful life or the lease.

Other Expense, Net

Other expense, net, which consists of interest expense, other expense and other income primarily consists of gain/loss on the sale of assets, foreign currency-related gains and losses, interest expense from servicing debt, and interest income on cash balances and investments as well as acquisition-related expenses and changes in fair value of contingent consideration. Our gain/loss on the sale of assets will vary each reporting period depending on occurrence of activity. Our foreign currency-related gains and losses will vary each reporting period depending upon movements in underlying exchange rates. Our interest expense will vary each reporting period based on the current level of variable interest rates associated with our outstanding debt obligations. Our interest income will vary each reporting period depending on our average cash balances during the period, composition of our marketable security portfolio and the current level of interest rates. Our acquisition-related expenses will vary each period based on activity and the appropriate treatment method of related costs. The fair value of our contingent consideration is subject to change each reporting period due to remeasurement under U.S. GAAP.

240

Income Taxes

Provision for income taxes primarily consists of federal and state income taxes for taxable subsidiaries. As we expand the scale of our business activities, any changes in the U.S. taxation of such activities may increase our overall provision for income taxes in the future. We currently do not have a valuation allowance for our U.S. deferred tax assets, including federal and state net operating losses (“NOLs”). No income tax expense or benefits have been recognized associated with uncertain tax positions.

241

Revenue for the nine months ended September 30, 2021 grew by $65.6 million or 155% compared with the same period in 2020, of which $1.9 million was organic and $63.7 million was inorganic through acquisition-related activity.

For the nine months ended September 30, 2021, our revenue growth by product line consisted of organic and inorganic growth as follows. Our additive revenue increased by $0.6 million, or 4%, of which 100% was organic revenue. Our injection molding revenue grew by $7.6 million, or 57%, of which 41% was organic and 59% was inorganic, driven by the Summit acquisition. Our CNC machining revenue grew by $22.0 million, or 271%, of which 100% of growth was inorganic driven by the Dahlquist, Mark Two, PPC, MPC, Centex, and Laser acquisitions. Our precision sheet metal revenue grew by $34.3 million, or 828%, of which 100% was inorganic, driven by the Incodema, Newcut, and Majestic acquisitions. Our other revenue grew by $1.2 million, or 29%, of which 100% was organic.

Our revenue increase in 2021 was the result of an increase in the volume of customers we served, primarily through acquisition-related activity as noted above. See Note 3 — Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information. We expect the number of customers served to grow in the long-term despite the challenges posed by the COVID-19 pandemic on the global economy. Steps taken by national and local governments to slow the spread of the virus, including business shutdowns and shelter in place orders, have hindered the ability and willingness of customers to proceed with development and commercialization projects on the same scale as they have historically. At this time, it is difficult to predict the future given the current economic uncertainty and evolving market conditions.

Cost of Revenue, Gross Profit and Gross Margin

Cost of Revenue. Cost of revenue increased $39.1 million, or 173%, for the nine months ended September 30, 2021 compared to the same period in 2020, which was approximately the same rate of revenue increase for the periods. The increase in cost of revenue was primarily driven by sales volume growth resulting from acquisition-related activities during the period. See Note 3 — Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Gross Profit and Gross Margin. Gross profit increased from $19.6 million for the nine months ended September 30, 2020 to $46.1 million for the same period in 2021 primarily due to an increase in revenue mainly attributable to sales volume growth resulting from acquisition-related activities during the period. Gross margin decreased from 46% of revenue for the nine months ended September 30, 2020 to 43% of revenue for the same period in 2021.

Operating Expenses

Selling, general, and administrative. Our selling, general, and administrative expense increased $16.0 million, or 119%, for the nine months ended September 30, 2021 compared to the same period in 2020 due to increases in salaries, wages, and commissions as well as digital marketing and professional fees driven by acquisition-related activities during the period. See Note 3 — Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Depreciation and amortization. Our depreciation and amortization expense increased $6.5 million, or 233%, for the nine months ended September 30, 2021 compared to the same period in 2020 due to increased fixed and intangible assets acquired with finite useful lives. The increases were primarily driven by acquisition-related activities during the period. See Note 3 — Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Income from Operations

Income from operations increased $4.0 million, or 120%, for the nine months ended September 30, 2021 compared with the same period in 2020. The increase in income from operations is primarily driven by the increases in revenue.

242

Other Expense, Net

We recognized other expense, net of $14.6 million for the nine months ended September 30, 2021, an increase of $10.2 million compared to other expense, net of $4.4 million for the same period in 2020. Other expense, net primarily consisted of $8.8 million and $2.3 million in interest expense, $9.0 million and $2.5 million in other expense, partially offset by $3.2 million and $0.4 million in other income for the nine months ended September 30, 2021 and 2020, respectively. The increase in interest expense during the current period was driven by debt-related activities during 2021 and 2020 in relation to acquisition-related activities in each respective period. See Note 3 — Business Combinations and Note 8 — Debt in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information. The increase in other expense during the current period was driven by acquisition-related activities in each respective period. See Note 3 — Business Combinations in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information. The increase in other income during the current period was driven by the change in fair value on contingent consideration and Paycheck Protection Program (“PPP”) loan forgiveness. See Note 8 — Debt and Note 12 — Fair Value Measurement in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Income Taxes

The Company’s effective income tax rate was 11.1% for the nine months ended September 30, 2021 compared with 0.0% in the same period in 2020, and the Company’s income tax expense was $0.8 million and $0.0 million for the periods, respectively. Refer to Note 14 — Income Taxes in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Total revenue	$	61,289		100	%	$	20,618		100	%	$	40,671		197	%

Revenue for the year ended December 31, 2020 grew by $40.7 million or 197% compared with 2019, of which 14% was organic and 86% was inorganic through acquisition-related activity. Our organic revenue was $19.4 million and $13.5 million or 32% and 66% of total revenue for the years ended December 31, 2020 and 2019, respectively.

For the year ended December 31, 2020, our revenue growth by product line consisted of organic and inorganic growth as follows. Our additive revenue grew by $7.6 million, or 66%, of which 14% was organic and 86% was inorganic, driven by $5.9 million from the FATHOM acquisition. Our injection molding revenue grew by $15.0 million, or 731%, of which 10% was organic and 90% was inorganic, driven by $10.1 million from the ICOMold acquisition and $3.4 million from the FATHOM acquisition. Our CNC machining revenue grew by $5.3 million, or 139%, of which 40% was organic and 60% was inorganic, driven by $2.7 million from the FATHOM acquisition. Our precision sheet metal revenue grew by $9.8 million, of which 100% was inorganic, driven by $6.5 million from the Incodema acquisition, $2.4 million from the Newchem acquisition, and $0.9 million from the Majestic Metals acquisition. Our other revenue grew by $2.9 million, or 89%, of which 41% was organic and 59% was inorganic, driven by the Incodema and FATHOM acquisitions.

Our revenue increase in 2020 was the result of an increase in the volume of customers we served, primarily through acquisition-related activity as noted above. See Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements for further information. We expect the number of customers served to grow in the long-term despite the challenges posed by the COVID-19 pandemic on the global economy. Steps taken by national and local governments to slow the spread of the virus, including business shutdowns and shelter in place orders, have hindered the ability and willingness of customers to proceed with development and commercialization projects on the same scale as they have historically. At this time, it is difficult to predict the future given the current economic uncertainty and evolving market conditions.

Cost of Revenue, Gross Profit and Gross Margin

Cost of Revenue. Cost of revenue increased $22.1 million, or 207%, for 2020 compared to 2019, which was more than the rate of revenue increase of 197% for 2020 compared to 2019. The increases were driven by raw material increases of $13.4 million as well as outsourced services and subcontract services increases of $5.5 million. The increase in cost of revenue was primarily driven by acquisition-related activities during the period. See Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements for further information.

Gross Profit and Gross Margin. Gross profit increased from $9.9 million in 2019 to $28.5 million in 2020 primarily due to an increase in revenue mainly attributable to an increase in Injection Molding and CNC Machining revenue for FATHOM and revenue from sales of parts for ICO Mold as compared to 2019. Gross margin decreased from 48% of revenue in 2019 to 46% of revenue in 2020 due to an increase of direct materials cost of ICOMold and MCT as compared to 2019.

244

Operating Expenses

Selling, general, and administrative. Our selling, general, and administrative expense increased $13.7 million, or 162%, for 2020 compared to 2019 due to an increase in salaries, wages and commissions of $5.9 million, an increase in advertising and marketing costs of $1.0 million, and an increase in professional fee expenses of $1.2 million. The increases in salaries, wages, and commissions as well as professional fees was primarily driven by acquisition-related activities during the period. See Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements for further information.

Depreciation and amortization. Our depreciation and amortization expense increased $3.2 million, or 201%, for 2020 compared to 2019 due to increased fixed and intangible assets acquired with finite useful lives. The increases were primarily driven by acquisition-related activities during the period. See Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements for further information.

Income from Operations

Income from operations increased $1.6 million, or 1,025%, for 2020 compared with 2019. The increase in income from operations is primarily driven by the increases in revenue.

Other Expense, Net

We recognized other expense, net of $9.4 million in 2020, an increase of $4.8 million compared to other expense, net of $4.6 million for 2019. Other expense, net for 2020 primarily consisted of $3.4 million in interest expense and $3.1 million in acquisition expenses. Other expense, net for 2019 primarily consisted of $1.5 million in interest expense and $2.0 million in acquisition expenses. The increase in interest expense during the current period was driven by debt-related activities during 2020 and 2019 in relation to acquisition-related activities in each respective period. See Note 3 — Business Combination and Note 8 — Long-term Debt in the accompanying Notes to the audited Consolidated Financial Statements for further information.

Liquidity and Capital Resources

We measure liquidity in terms of our ability to fund the cash requirements of our business operations, including working capital and capital expenditure needs, contractual obligations and other commitments, with cash flows from operations and other sources of funding. Our current working capital needs relate mainly to our growth strategies, including business combination activity, capital equipment investments, and business development efforts, as well as compensation and benefits of our employees. In addition, under our credit agreements, the Company is subject to various financial covenants, including quarterly fixed-charge coverage ratio; total leverage ratio; and minimum adjusted earnings before interest, taxes, depreciation, and amortization (AEBITDA). As of the Nine months Ended September 30, 2021, the Company has remained in compliance with all covenant requirements. Our ability to expand and grow our business will depend on many factors, including our working capital needs and the evolution of our operating cash flows.

In addition, as of September 30, 2021 we have contingent consideration payable to former shareholders of $8.6 million related to acquisitions made in 2020 and 2021. This amount represents our best estimate of the fair value of the contingent consideration that will ultimately be paid in future periods as of the period ended September 30, 2021. However, the amount could be materially higher or lower depending on future economic performance of the acquired businesses. See Note 12 — Fair Value Measurement in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

We had $10.5 million in cash as of September 30, 2021. We believe our operating cash flows, together with amounts available under our term loan and revolving credit facility, our cash on hand and the cash we expect to

245

obtain from the New Credit Agreement as a result of the Business Combination will be sufficient to meet our working capital and capital expenditure requirements once the Business Combination closes. See the Going Concern section above for discussion of the committed financing expected to be funded upon closing of the Business Combination.

We may, however, need additional cash resources due to changed business conditions or other developments, including unanticipated regulatory developments, significant acquisitions and competitive pressures. We expect our capital expenditures and working capital requirements to continue to increase in the immediate future, as we seek to expand our product offerings across more of the United States. Our recent annual capital expenditures have varied between 3.0% and 4.0% of annual revenue. We believe future growth capital expenditures, excluding any expenditures for buildings and maintenance capital we might purchase for our operations, are likely to vary between approximately 3.0% and 5.0% of annual revenue. To the extent that our current resources are insufficient to satisfy our cash requirements, we may need to seek additional equity or debt financing. If the needed financing is not available, or if the terms of financing are less desirable than we expect, we may be forced to decrease our level of investment in new product launches and related marketing initiatives or to scale back our existing operations, which could have an adverse impact on our business and financial prospects. See Note 3 — Business Combination to our audited Consolidated Financial Statements and unaudited Condensed Consolidated Financial Statements included elsewhere in this proxy statement/prospectus.

Borrowings and Lines of Credit

We had $170.3 million in total debt outstanding as of September 30, 2021. Our debt has primarily been used in the financing of our business combinations.

On August 31, 2018, the Company entered into a $15 million term loan, a $10 million delayed draw term loan, and a revolving credit agreement permitting aggregate borrowings of up to $1.5 million with a bank that provided a secured, unsubordinated term loan credit facility with a maturity of August 23, 2023. On December 2, 2019, the Company entered into the third amendment to the 2018 Credit Facilities. Pursuant to the amendment, an additional $15 million term loan was issued as part of financing for the ICOMold acquisition as described in Note 3 — Business Combination to our audited Consolidated Financial Statements. Collectively, this debt is referred to as the “2018 and 2019 Credit Facilities.” On August 18, 2020, the Company drew $2 million on the delayed draw term loan as part of financing for the GPI acquisition as described in Note 3 — Business Combination to our audited Consolidated Financial Statements.

On July 27, 2020, the Company entered into a $34.5 million secured, unsubordinated credit facility (the “2020 Credit Facilities”) with a financial institution, consisting of a $19.5 million term loan and a $15 million delayed draw term loan, with a maturity of July 27, 2026. At closing, $19.5 million was funded and along with cash on the Company’s balance sheet, used to finance the acquisition of Incodema and Newchem as discussed in Note 3 — Business Combination to our audited Consolidated Financial Statements. On December 16, 2020, the Company entered into the first amendment to the 2020 Credit Facility. Pursuant to the amendment, the availability on the delayed draw term loan was increased to $40.5 million and was drawn on as part of the financing as part of the Dahlquist, Mark Two, and Majestic Metals as discussed in Note 3 — Business Combination to our audited Consolidated Financial Statements.

During the year ended December 31, 2020, the Company received a PPP loan in the amount of $1.6 million through the Small Business Administration (SBA) under the Coronavirus Aid, Relief, and Economic Security (CARES). All PPP loans have been forgiven as of September 30, 2021.

As previously discussed in the Going Concern section, on April 30, 2021, the Company completed a financing transaction whereby it issued a $172 million term loan due April 2022 (the “2021 Term Loan”) in order to finance the acquisitions of Centex Machine and Welding, Inc. (“Centex”), Laser Manufacturing, Inc. (“Laser”), Sureshot Precision, LLC d/b/a Micropulse West (“Micropulse West”), and Precision Process

246

Corporation (“PPC”), as well as to refinance the Company’s existing debt, as described above and in Note 8 — Long-Term Debt and Note 20 — Subsequent Events in the accompanying Notes to the audited Consolidated Financial Statements.

To address the upcoming maturity of the 2021 Term Loan and a lack of sufficient cash on hand and cash flow from operations to repay the Term Loan, the Company has entered into a new credit facility with its existing creditors (the “New Credit Agreement”). The New Credit Agreement includes a $50 million revolving credit facility and $125 million term loan and matures in 2026. The proceeds from these loans will be used to repay the 2021 Term Loan; however, the funding of the New Credit Agreement is contingent on the Company closing a definitive business combination with a publicly traded Special Purpose Acquisition Company (“SPAC”) before April 9, 2022 (the “SPAC Transaction”). See the Going Concern section above for further discussion of the committed financing expected to be funded upon closing of the SPAC Transaction. Additionally, see Note 8 — Debt in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements.

Cash Flows

The following table summarizes our cash flows for the each of the periods presented:

	Nine months Ended September 30,						Year Ended December 31,
($ in thousands)	2021			2020			2020			2019
Cash provided by (used in):
Operating activities	$	1,737		$	2,789		$	1,870		$	(591	)
Investing activities		(74,076	)		(41,693	)		(96,038	)		(44,368	)
Financing activities		74,682			44,335			101,330			43,766
Net increase (decrease) in cash	$	2,343		$	5,431		$	7,162		$	(1,193	)

Sources of Liquidity

We finance our operations and capital expenditures through cash flows from operations while our acquisition-related activities are primarily financed through the issuance of long-term debt as discussed above. We had cash of $10.5 million as of September 30, 2021, an increase of $4.1 million from September 30, 2020. The increase in our cash was due primarily to cash generated through obtaining additional debt financing offset by cash used for acquisitions.

As of September 30, 2021, the amount of cash held by foreign subsidiaries was $0.5 million. Our intent is to continue to permanently reinvest these funds outside the U.S. and our current plans do not demonstrate a need to repatriate them to fund our domestic operations. We believe that our existing cash together with cash generated from operations as well as closings of the New Credit Agreement and the Business Combination will be sufficient to meet our working capital expenditure requirements for at least the next 12 months. See the Going Concern section above for discussion of the committed financing expected to be funded upon closing of the Business Combination.

Cash Flows from Operating Activities

The cash flow from operating activities for the nine months ended September 30, 2021 compared to the same period in 2020 decreased $1.1 million due to a greater net loss reported in the period resulting from higher operating expenses, as well as a carrying a higher accounts payable balance at the end of the period, both of which were driven by acquisition and integration-related activities. These drivers were partially offset by the changes in receivables.

247

The cash flow from operating activities during 2020 compared to 2019 increased $2.5 million due to increases in revenue from new product lines, which were partially offset by increased costs associated with these new product lines.

Cash Flows used in Investing Activities

Cash used in investing activities was $74.1 million for the nine months ended September 30, 2021 compared to $41.7 million for the nine months ended September 30, 2020 with the increase due to cash used for the acquisitions of Summit, Centex, Laser, Micropulse West, and PPC.

Cash used in investing activities was $96.0 million for the year ended December 31, 2020 compared to $44.4 million for the year ended December 31, 2019 with the increase due to cash used for the acquisitions of Incodema, Newchem, Dahlquist, Mark Two and Majestic Metals.

Cash Flows from Financing Activities

Cash generated from financing activities was $74.7 million for the nine months ended September 30, 2021, consisting of $183.5 million in proceeds from the issuance of new debt, partially offset by $104.1 million in repayments on debt, $1.7 million in debt issuance cost payments, and $3.0 million in contingent considerations payments. Cash generated in financing activities was $44.3 million for the nine months ended September 30, 2020, consisting of $22.7 million in proceeds from the issuance of new debt and $21.6 million in proceeds from the issuance of members’ units. The increase in cash was driven by financing requirements for the acquisitions made by the Company in 2020 and 2021.

Cash generated in financing activities was $101.3 million for the year ended December 31, 2020, consisting of $65.1 million in proceeds from the issuance of new debt, and $40.5 million in proceeds from issuances of members’ units, partially offset by $1.7 million in repayments on debt and $1.4 million of payments for contingent considerations. Cash generated in financing activities was $43.8 million for the year ended December 31, 2019, consisting of $32.1 million in proceeds from issuances of members’ units and $16 million in proceeds from the issuance of new debt, partially offset by $3.5 million in payments for contingent considerations. The increase in cash was driven by financing requirements for the acquisitions made by the Company in 2020.

Contractual Obligations

We extend a variety of financial guarantees to third parties in support of our business. We also have obligations arising from environmental, health and safety, tax and employment matters. Circumstances that could cause the contingent obligations and liabilities arising from these arrangements to come to fruition include changes in an underlying transaction, non-performance under a contract or deterioration in the financial condition of the guaranteed party.

As of September 30, 2021, our contractual obligations and the effect such obligations are expected to have on our liquidity and cash flows in future periods were as follows:

($ in thousands)	Total		Less than 1 Year		2 to 3 Years		4 to 5 Years		Thereafter
Operating leases	$	14,659	$	3,683	$	6,201	$	2,738	$	2,037
Contingent consideration		8,630		6,330		2,300		—		—
Debt — principal		172,000		172,000		—		—		—
Interest on debt		8,338		8,338		—		—		—
Total contractual obligations	$	203,627	$	190,351	$	8,501	$	2,738	$	2,037

248

Our commitments for operating leases relate to future contractual payments on our leases for land and buildings, vehicles and machinery and equipment at our United States manufacturing facilities and our China manufacturing facility.

Debt includes current maturities. See Note 8 — Debt in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements.

Interest on debt represents our best estimate of future interest payments based on contractual terms. This amount could be materially higher or lower depending on future interest rate fluctuations and their impact on our variable rate debt. See Note 8 — Debt in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements.

Contingent consideration relates to amounts payable to former shareholders as a result of acquisitions made in 2020 and 2021. This amount represents our best estimate of the fair value of the contingent consideration that will ultimately be paid in future periods as of the period September 30, 2021. However, the amount could be materially higher or lower depending on future economic performance of the acquired businesses. See Footnote 12 — Fair Value Measurement in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Off-Balance Sheet Arrangements

Since our inception, we have not engaged in any off-balance sheet arrangements, including the use of structured finance, special purpose entities or variable interest entities.

Critical Accounting Policies and Use of Estimates

Preparation of our financial statements requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, sales and expenses. Note 2 — Significant Accounting Policies in the accompanying Notes to the audited Consolidated Financial Statements describes the significant accounting policies used in preparation of the Consolidated Financial Statements. We believe that the most complex and sensitive judgments, because of their potential significance to the Consolidated Financial Statements, result primarily from the need to make estimates about the effects of matters that are inherently uncertain and are described subsequently. Actual results could differ from management’s estimates.

Business Combinations

We account for business acquisitions in accordance with ASC 805, Business Combinations. We measure the cost of an acquisition as the aggregate of the acquisition date fair values of the assets transferred and liabilities assumed and equity instruments issued. Transaction costs directly attributable to the acquisition are expensed as incurred. We record goodwill for the excess of (i) the total costs of acquisition, fair value of any non-controlling interests and acquisition date fair value of any previously held equity interest in the acquired business over (ii) the fair value of the identifiable net assets of the acquired business.

The acquisition method of accounting requires us to exercise judgment and make estimates and assumptions based on available information regarding the fair values of the elements of a business combination as of the date of acquisition, including the fair values of identifiable intangible assets, deferred tax asset valuation allowances, liabilities related to uncertain tax positions and contingencies. We must also refine these estimates over a one-year measurement period, to reflect any new information obtained about facts and circumstances that existed as of the acquisition date that, if known, would have affected the measurement of the amounts recognized as of that date. If we are required to retroactively adjust provisional amounts that we have recorded for the fair value of assets and liabilities in connection with an acquisition, these adjustments could materially impact our results of operations and financial position. Estimates and assumptions that we must make in estimating the fair value of

249

future acquired technology, user lists and other identifiable intangible assets include future cash flows that we expect to generate from the acquired assets. If the subsequent actual results and updated projections of the underlying business activity change compared with the assumptions and projections used to develop these values, we could record impairment charges. In addition, we have estimated the economic lives of certain acquired assets and these lives are used to calculate depreciation and amortization expense. If our estimates of the economic lives change, depreciation or amortization expenses could be accelerated or slowed, which could materially impact our results of operations.

Goodwill and Intangible Assets

We recognize goodwill in accordance with ASC 350, Intangibles—Goodwill and Other. Goodwill is the excess of cost of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually as of October 1st of each year, and is tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. An impairment charge for goodwill is recognized only when the estimated fair value of a reporting unit, including goodwill, is less than its carrying amount. In 2020, we performed a qualitative and quantitative analysis based on the significance of the fair value over the carrying value in prior period assessments. As of December 31, 2020 and September 30, 2021, no impairment charges for goodwill have been recognized.

We recognize intangibles assets in accordance with ASC 350, Intangibles—Goodwill and Other. Acquired intangible assets subject to amortization are stated at cost and are amortized using the straight-line method over the estimated useful lives of the assets. Intangible assets that are subject to amortization are reviewed for potential impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. Assets not subject to amortization are tested for impairment at least annually. As of December 31, 2020 and September 30, 2021, no impairment charges for intangible assets have been recognized.

The estimates of fair value are based on the best information available as of the date of the assessment, which primarily incorporates management assumptions about expected future cash flows. Although these assets are not currently impaired, there can be no assurance that future impairments will not occur. See Note 3 — Business Combination and Note 7 — Goodwill and Intangible Assets in the accompanying Notes to the audited Consolidated Financial Statements and Note 3 – Business Combination and Note 7 — Goodwill and Intangible Assets in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for further information.

Revenue Recognition from Contracts with Customers

On January 1, 2019, the Company adopted ASC 606, Revenue from Contracts with Customers, using the modified retrospective approach. Most of the Company’s revenue has one performance obligation and is recognized on a point-in-time basis upon shipment. The majority of the Company’s injection molding contracts have multiple performance obligations including one obligation to produce the mold and sample part and a second obligation to produce production parts. For injection molding contracts with multiple performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price and recognizes revenue for each performance obligation on a point-in-time basis upon shipment. We generally determine standalone selling price based on the price charged to customers. The Company’s payments terms are consistent with industry standards and never exceed 12 months. The adoption of ASC 606 did not have a material impact on our Consolidated Financial Statements.

Contingent Liabilities

Our contingent liabilities, which are included within the “other long-term liabilities” caption on our consolidated balance sheets, are uncertain by nature and their estimation requires significant management

250

judgment as to the probability and estimation of the amount of liability. These contingencies include, but may not be limited to, earnout payments, litigation, and management’s evaluation of complex laws and regulations, including those relating to indirect taxes, and the extent to which they may apply to our business and industry. See Note 17 — Fair Value Measurement and Note 18 — Commitments and Contingencies in the accompanying Notes to the audited Consolidated Financial Statements and Note 12 — Fair Value Measurement and Note 13 — Commitments and Contingencies in the accompanying Notes to the unaudited Condensed Consolidated Financial Statements for more information.

We regularly review our contingencies to determine whether the likelihood of la liability is probable and to assess whether a reasonable estimate of the liability can be made. Determination of whether a liability estimate can be made is a complex undertaking that considers the judgement of management, third-party research, the prospect of negotiation and interpretations by regulators and courts, among other information. When liabilities can be reasonably estimated, an estimated contingent liability is recorded. We continually reevaluate our indirect tax and other positions for appropriateness.

Share-Based Compensation

We determine our share-based compensation in accordance with ASC 718, Compensation—Stock Compensation (ASC 718), which requires the measurement and recognition of compensation expense for all share-based payment awards made to employees based on the grant date fair value of the award.

Determining the appropriate fair value model and calculating the fair value of phantom award grants requires the input of subjective assumptions. We use the Black-Scholes pricing model to value our phantom awards. Share-based compensation expense is calculated using our best estimates, which involve inherent uncertainties and the application of management’s judgment. Significant estimates include our expected volatility. If different estimates and assumptions had been used, our phantom unit valuations could be significantly different and related share-based compensation expense may be materially impacted.

The Black-Scholes pricing model requires inputs such as the risk-free interest rate, expected term, expected volatility and expected dividend yield. We base the risk-free interest rate that we use in the Black-Scholes pricing model on zero coupon U.S. Treasury instruments with maturities similar to the expected term of the award being valued. The expected term of phantom awards is estimated from the vesting period of the award and represents the weighted average period that our phantom awards are expected to be outstanding. We estimated the volatility based on the historic volatility of our guideline companies, which we feel best represent our company. We have never paid and do not anticipate paying any cash dividends in the foreseeable future and, therefore, we use an expected dividend yield of zero in the pricing model. We account for forfeitures as they occur.

The fair value of each award granted was estimated on the date of grant for the periods below using the Black-Scholes pricing model with the following weighted-average assumptions:

	2020			2019
Risk-free interest rate		0.28	%		2.24	%
Expected term		4.65			4.47
Expected volatility		76.67	%		73.55	%
Expected dividend yield		0.00	%		0.00	%
Weighted average grant date fair value, time-vested units	$	57.69		$	98.37
Weighted average grant date fair value, performance-vested units	$	49.96		$	87.51

If in the future we determine that another method for calculating the fair value of our phantom awards is more reasonable, or if another method for calculating the above input assumptions is prescribed by authoritative guidance, the fair value calculated for our phantom awards could change significantly.

251

There are significant differences among valuation models, and this may result in a lack of comparability with other companies that use different models, methods and assumptions. If factors change and we employ different assumptions in the application of ASC 718 in future periods, or if we decide to use a different valuation model, such as a lattice model, the share-based compensation expense that we record in the future under ASC 718 may differ significantly from what we have recorded using the Black-Scholes pricing model and could materially affect our operating results.

We allocate share-based compensation expense for time-vested awards on a straight-line basis over the requisite service period. We recorded share-based compensation expense of $31 thousand and $22 thousand for the nine months ended September 30, and September 30, 2020, respectively. We recorded share-based compensation expense of $34 thousand and $21 thousand during 2020 and 2019, respectively. As of December 31, 2020, we had $554 thousand of unrecognized share- based compensation costs, net of estimated forfeitures, that is expected to be recognized over a weighted average period of 2.8 years.

Performance-vested awards are contingent on a change-in-control event or on the closing of a transaction with a special purpose acquisition company (SPAC). Recognition of share-based compensation expense for these awards is based on the likelihood of a change-in-control event or SPAC transaction being probable, which per U.S. GAAP is not considered probable until the such an event occurs.

In future periods, our share-based compensation expense is expected to increase due to the issuance additional share-based awards, potential for a change-in-control event, and our existing unrecognized share-based compensation.

Phantom Award Valuation

The fair value of our phantom units is used to determine the expense recognition of equity-based payments made to employees. Because we are a privately held company with no public market for our equity units, our board of directors has considered numerous objective and subjective factors in determining the value of phantom units in accordance with the guidance provided by the American Institute of Certified Public Accountants Practice Aid, Valuation of Privately-Held-Company Equity Securities Issued as Compensation. These objective and subjective factors include:

• recent valuation analysis furnished by either an independent third-party valuation specialist or a professional investor in our company;

• our stage of development;

• actual and forecasted operating and financial performance;

• our capital resources or financial condition;

• trends and risks in our industry;

• U.S. and global capital market conditions;

• the preferences of our preferred and common units relative to those of common stock;

• the lack of a public market for our equity units; and

• the prospects for increased liquidity in our equity units through an initial public offering, sale of our company or otherwise.

Valuations that we have performed require significant use of estimates and assumptions. If different estimates and assumptions had been used, our equity unit valuations could be significantly different and related share-based compensation expense may be materially impacted.

The following table summarizes, by grant date, the number of vesting-type units underlying phantom awards granted since January 1, 2019 and the grant date fair value as of the respective valuation dates.

In April 2021, our board of directors obtained valuation analyses as of each of the valuation dates noted in the table above from an independent third-party valuation specialist, which it utilized in part in connection with its fair value determination for the respective award grants. The January 1, 2019, October 1, 2019, and October 1, 2020 valuations dates relate to MCT Holdings, while the July 27, 2020 valuation date relates to Incodema Holdings. The approach for both entities was the same. In determining the fair value of our phantom units for these grants, our board used the market approach and income approach valuation methods that were also used by the third-party valuation specialist. Market approaches are a general way of determining a value indication of a business ownership interest or security by using one or more methods that compare the subject to similar businesses, business ownership interests, or securities that are publicly traded or have been sold. In the market approach, estimates of market value are developed by comparing our company to selected publicly traded companies or acquired companies that possess similar business risks and returns. On the basis of the comparative analysis, valuation multiples derived from the guideline companies are applied to financial data of our company to develop an indication of the enterprise value.

In the income approach, our board utilized the discounted cash flow method to determine an indication of value. In the discounted cash flow method, several years of future cash flows are estimated. These cash flows are then discounted to a present value using a discount rate that our board believed to be appropriate to compensate for the risk of attaining the projected cash flows. The discounted cash flow method is a multi-period income approach because it considers multiple years of income and cash flow. This valuation method is highly sensitive to projected future performance as well as selected terminal multiples and discount rates. A weighted average cost of capital of 15.9%, 14.9%, 23.5%, and 14% for each of the subsidiary valuation dates January 1, 2019, October 1, 2019, July 27, 2020, and October 1, 2020, respectively, were used in our board’s analysis. Our board believed the discounted cash flow method provided the most relevant indication of our company’s enterprise value given our projected growth. Our board concluded that it was appropriate to rely on the valuations as of each date for purposes of the respective grants in the table above, in large part based on its determination that there were no significant changes in our business, including our recent and forecasted financial results, between each of the grant dates and the date of their respective valuations.

Recently adopted accounting pronouncements

During the year ended 2020, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers, which is intended to provide financial statement users with a single model for accounting for revenue arising from contracts with customers and supersedes previous revenue guidance, including industry-specific revenue guidance. The adoption of this guidance had no material impact on our Consolidated Financial Statements.

Recently issued accounting pronouncements

See Note 2 — Significant Accounting Policies to our audited Consolidated Financial Statements included in this filing on Form 8-K for a description of recently issued accounting pronouncements applicable to our financial statements.

Emerging Growth Company Accounting Election

Section 102(b)(1) of the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”) exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can choose not to take advantage of the extended transition period and comply with the requirements that apply to non-emerging growth companies, and any such election to not take advantage of the extended transition period is irrevocable. Altimar II is an “emerging growth company” as defined in Section 2(a) of the Securities Act of 1933, as amended, and has elected to take advantage of the benefits of this extended transition period. Following the consummation of the Business Combination, Fathom is expected to remain an emerging growth company at least through the end of the 2021 fiscal year and is expected to continue to take advantage of the benefits of the extended transition period. This may make it difficult or impossible to compare Fathom financial results with the financial results of another public company that is either not an emerging growth company or is an emerging growth company that has chosen not to take advantage of the extended transition period exemptions for emerging growth companies because of the potential differences in accounting standards used.

Supplemental Unaudited Pro Forma Combined Financial Information

Comparability of Pro Forma Financial Results

During 2019 we completed the acquisitions of FATHOM and ICO Mold (the “2019 Acquisitions”). During 2020 we completed the acquisitions of Incodema, Newchem, GPI, Dahlquist, Majestic Metals, and Mark Two (the “2020 Acquisitions” and together with the 2019 Acquisitions, the “Prior Acquisitions”). During 2021 we completed the acquisitions of Summit, Centex, Laser, Precision Process, and Micropulse West (the “2021 Acquisitions”) as discussed in further detail in Note 3 — Business Combination in the accompanying Notes to the audited Consolidated Financial Statements and Interim Consolidated Financial Statements. The Prior Acquisitions and 2021 Acquisitions resulted in, among other things, a considerable increase in amortizable intangible assets and goodwill. The amortization of acquired intangibles has materially increased our consolidated depreciation and amortization expense for periods after the acquisition and is expected to continue to do so for the foreseeable future.

The preceding discussion of our results of operations for the twelve months ended December 30, 2019 and 2020 and for the nine months ended September 30, 2021 and 2020 includes the financial results of the Prior Acquisitions and 2021 Acquisitions from the date following the respective acquisitions through September 30, 2021. Accordingly, our consolidated results of operations for the twelve months ended December 31, 2020 and the nine months ended September 30, 2021 are not comparable to our consolidated results of operations for prior periods and may not be comparable with our consolidated results for future periods. To facilitate comparability between periods, we have included in this proxy statement/prospectus a supplemental discussion of our unaudited pro forma results of operations for the twelve months ended December 31, 2020 compared with the same period in 2019, and for the nine months ended September 30, 2021 compared with the same period in 2020.

The pro forma results for the years ended December 31, 2020 and 2019 were prepared giving effect to the Prior Acquisitions as if they had been consummated on January 1, 2019. The pro forma results for the nine months ended September 30, 2021 and 2020 were prepared giving effect to the 2020 Acquisitions and 2021 Acquisitions as if they had been consummated on January 1, 2020.

Unaudited Pro Forma Results for the Nine months Ended September 30, 2021 Compared to the Nine months Ended September 30, 2020

The following tables summarize our pro forma results of operations for the nine months ended September 30, 2021 and 2020. They are not the results that would have been realized had the Prior Acquisitions actually occurred on January 1, 2019 and the 2021 Acquisitions actually occurred on January 1, 2020 and are not indicative of our consolidated results of operations for future periods.

Pro Forma Revenue by Product Line

Pro forma revenue by product line and the related changes for the nine months ended September 30, 2021 and 2020 is summarized as follows:

	Pro Forma (unaudited) Nine months Ended September 30,
($ in thousands)	2021					2020					Change
	$		% of Total Revenue			$		% of Total Revenue			$			%
Revenue
Additive manufacturing		13,316		11	%		12,827		11	%		489			4%
Injection molding		21,353		18	%		17,962		16	%		3,391			19%
CNC machining		40,331		34	%		44,674		40	%		(4,343	)		(10%)
Precision sheet metal		38,189		32	%		31,613		28	%		6,576			21%
Other revenue		5,065		4	%		4,869		4	%		196			4%
Total revenue		118,254		100	%		111,945		100	%		6,309			6%

By product line, our revenue increase was driven by a 21% increase in Precision Sheet Metal revenue, a 19% increase in Injection Molding revenue, a 4% increase to Additive Manufacturing revenue, and a 4% increase in other revenue, offset by a 10% decrease in CNC machining revenue for the nine months ended September 30, 2021 compared with the same period in 2020.

Revenue. Pro forma revenue increased by $6.3 million, or 6%, to $118.3 million for the nine months ended September 30, 2021 from $111.9 million for the nine months ended September 30, 2020. Our revenue growth was driven by our strategic account focused sales and marketing strategy as well as increases to our injection molding product line, resulting from more hybridized customer solutions combining our additive and injection molding product lines, and our precision sheet metal product line.

Cost of revenue. Pro forma cost of revenue increased by $8.0 million, or 14%, to $66.2 million for the nine months ended September 30, 2021 from $58.2 million for the nine months ended September 30, 2020. This increase is driven by higher order volumes and modest raw material price increase compared to the prior year.

Selling, general, and administrative expenses. Pro forma selling, general, and administrative expenses decreased by $0.5 million, or 1%, to $32.9 million for the nine months ended September 30, 2021 from $33.3 million for the nine months ended September 30, 2020. This decrease was driven by utilities and professional services fee decreases.

Depreciation and amortization. Pro forma depreciation and amortization expense decreased by $0.7 million, or 7%, to $10.5 million for the nine months ended September 30, 2021 from $11.2 million for the nine months ended September 30, 2020. This decrease was primarily attributable to the consolidation of manufacturing for select acquired entities and the disposition and ending of service life of certain assets.

Interest expense. Pro forma interest expense decreased by $7.0 million, or 100%, for the nine months ended September 30, 2021 from the nine months ended September 30, 2020, because the debt would have been repaid.

Other expense. Pro forma other expense increased by $6.0 million to $9.4 million for the nine months ended September 30, 2021 from $3.4 million for the nine months ended September 30, 2020. This increase was driven by higher transaction expenses.

Other income. Pro forma other income increased by $3.5 million to $3.9 million for the nine months ended September 30, 2021 from $0.4 million for the nine months ended September 30, 2020. This increase was driven by the forgiveness of Paycheck Protection Program loans and the change in fair value of contingent consideration.

258

Income taxes. Pro forma income taxes increased by $0.5 million to $0.9 million for the nine months ended September 30, 2021 from $0.4 million for the nine months ended September 30, 2020. This decrease was driven primarily by a decrease in taxable income at certain entities.

Net income (loss). Pro forma net income increased by $3.4 million to $2.3 million for the nine months ended September 30, 2021 from a net loss of $1.2 million for the nine months ended September 30, 2020, for the reasons discussed above.

Pro Forma Revenue by Product Line

Pro Forma revenue by product line and the related changes for 2020 and 2019 is summarized as follows:

	Pro Forma (unaudited) Year Ended December 31,
($ in thousands)	2020					2019					Change
	$		% of Total Revenue			$		% of Total Revenue			$		%
Revenue
Additive manufacturing	$	19,228		17	%	$	19,048		20	%	$	180		1	%
Injection molding		17,269		16			12,074		12			5,195		43
CNC machining		22,739		21			18,076		19			4,663		26
Precision sheet metal		45,103		41			41,597		43			3,506		8
Other revenue		6,244		5			6,225		6			19		0
Total revenue	$	110,583		100	%	$	97,020		100	%	$	13,563		14	%

By product line, our revenue increase was driven by a 43% increase in Injection Molding revenue, a 26% increase in CNC Machining revenue, an 8% increase in Precision Sheet Metal, and a 1% increase in Additive Manufacturing revenue in each case for 2020 compared with 2019.

Revenue. Pro forma revenue increased by $13.6 million, or 14%, to $110.6 million in 2020 from $97.0 million in 2019. Our revenue growth was driven by our strategic account focused sales and marketing strategy as well as increases to our injection molding product line, resulting from more hybridized customer solutions combining our additive and injection molding product lines, and our CNC machining product line.

Cost of revenue. Pro forma cost of revenue increased by $3.7 million, or 7%, to $57.5 million in 2020 from $53.8 million in 2019. This increase is driven by higher order volumes and modest raw material price increase compared to the prior year.

Selling, general, and administrative expenses. Pro forma selling, general, and administrative expenses increased by $8.2 million, or 29%, to $36.6 million in 2020 from $28.4 million in 2019. This increase was driven by headcount growth and related fringe benefit costs as well as insurance, utilities, and professional services fee increases.

Depreciation and amortization. Pro forma depreciation and amortization expense decreased by $0.7 million, or 6%, to $11.5 million in 2020 from $12.3 million in 2019. This decrease was primarily attributable to the consolidation of manufacturing for select acquired entities and the disposition and ending of service life of certain assets.

Interest expense. Pro forma interest expense increased $0.6 million, or 9%, to $7.5 million in 2020 from $6.9 million in 2019 due to additional interest related to our outstanding credit facilities.

Other expense. Pro forma other expense increased by $0.6 million, or 9%, to $7.8 million in 2020 from $7.1 million in 2019. This increase was driven by lower transaction expenses.

Other income. Pro forma other income increased by $2.6 million to $2.8 million in 2020 from $0.2 million in 2019. This increase was driven by forgiveness of PPP loans.

Net income (loss). Pro forma net income (loss) decreased by $3.8 million, or 34%, to $(7.4) million in 2020 from $(11.2) million in 2019, for the reasons discussed above.

Quantitative and Qualitative Disclosure of Market Risks

We are exposed to fluctuations in foreign currency exchange rates and interest rates.

Foreign Currency Exposures

As a result of our foreign operations, we have revenue, expenses, assets and liabilities that are denominated in foreign currency. We generate revenue and incur production costs and operating expenses in Chinese Yuan.

Our operating results and cash flows are adversely impacted when the United States dollar appreciates relative to other foreign currencies. As we expand internationally, our results of operations and cash flows will become increasingly subject to changes in foreign currency exchange rates.

We have not used forward contracts or currency borrowings to hedge our exposure to foreign currency risk. Foreign currency risk can be assessed by estimating the change in results of operations or financial position resulting from a hypothetical 10% adverse change in foreign exchange rates. We believe such a change would generally not have a material impact on our financial position, or on our results of operations. We recognized foreign currency gain of $0.1 million for the nine months ended September 30, 2021, a foreign currency loss of $0.1 million for the year ended December 31, 2020 and no foreign currency activity for the year ended December 31, 2019.

Interest Rate Exposures

Our long-term debt consists of variable-rate instruments, which exposes us to changes in interest rates and may impact our pretax earnings and cash flows. At September 30, 2021, we had total variable rate debt outstanding under our New Credit Agreement of approximately $170 million. If the effective interest rate of our variable rate debt outstanding as of September 30, 2021 were to increase by 100 basis points (1%), our interest expense for the first nine months ended September 30, 2021 would increase by approximately $1.3 million. Currently, we do not hold any derivative contracts that hedge our interest rate exposures, but may consider such strategies in the future.

EXECUTIVE COMPENSATION

Altimar II Executive and Director Compensation

The following disclosure concerns the compensation of Altimar II’s executive officers and directors from inception (i.e., pre-business combination).

None of Altimar II’s executive officers or directors have received any cash compensation for services rendered to Altimar II. Since the consummation of Altimar II’s initial public offering and until the earlier of the consummation of the initial business combination and Altimar II’s liquidation, Altimar II will reimburse the Sponsor for office space and secretarial and administrative services provided to Altimar II, in an amount not to exceed $10,000 per month. In addition, Altimar II’s Sponsor, executive officers and directors and their respective affiliates are being reimbursed for any out-of-pocket expenses incurred in connection with activities conducted on Altimar II’s behalf, such as identifying potential target businesses and performing due diligence on suitable business combinations. Altimar II’s audit committee reviews all payments that Altimar II makes to the Sponsor, executive officers and directors and their respective affiliates on a quarterly basis. Any such payments prior to an initial business combination are made using funds held outside of the Trust Account. Other than quarterly audit committee review of such reimbursements, Altimar II does not have any additional controls in place for governing reimbursement payments to its directors and executive officers for their out-of-pocket expenses incurred on behalf of Altimar II and in connection with identifying and consummating an initial business combination. Other than these payments and reimbursements, no compensation of any kind, including finder’s and consulting fees, is paid by Altimar II to the Sponsor, executive officers and directors or any of their respective affiliates, prior to completion of the initial business combination.

Pre-Business Combination Company Executive Officer and Director Compensation

Introduction

As an emerging growth company, we have opted to comply with the executive compensation disclosure rules applicable to “smaller reporting companies,” as such term is defined in the rules promulgated under the Securities Act. This section discusses the material components of the executive compensation program for our Chief Executive Officer and our two other most highly compensated officers whom we refer to as our “Named Executive Officers”.

Background on Named Executive Officer Determination

Fathom OpCo was formed in 2021, at which time, in connection with a series of transactions (the “Reorganization”) it became the direct parent to MCT Group Holdings, LLC (and its subsidiaries), a Delaware limited liability company (“MCT Holdings”), and Incodema Holdings, LLC, a Delaware limited liability company (“Incodema”). As of December 31, 2020, MCT and Incodema were under the common control of CORE Industrial Partners. Fathom OpCo’s named executive officers (“Named Executive Officers” or “NEOs”) for purposes of this disclosure were determined by reviewing the total compensation for the 2020 fiscal year for each employee of MCT Holdings (and its subsidiaries) and Incodema Holdings (and its subsidiaries) who would be considered an executive officer of such entities, or Fathom OpCo if it had existed on December 31, 2020 and was then the direct parent of MCT Holdings and Incodema. Because Incodema was not acquired by CORE Industrial Partners until July 15, 2020, the three most highly compensated executive officers serving on December 31, 2020 for Fathom OpCo for purposes of this disclosure were all employees of MCT Holdings (and its subsidiaries) (the “MCT Group”).

For the year ended December 31, 2020, Fathom OpCo’s NEOs were:

• Ryan Martin, Chief Executive Officer of MCT Group;

• Richard Stump, Chief Commercial Officer of MCT Group; and

• Brian Freeburg, Chief Financial Officer of MCT Group.

267

Our Compensation Program

The objective of Fathom OpCo’s compensation program is to provide a total compensation package to each NEO that will enable Fathom OpCo to attract, motivate and retain outstanding individuals, align the interests of our executive team with those of our stockholders, encourage individual and collective contributions to the successful execution of our short and long-term business strategies, and reward NEOs for performance. The board of managers of MCT Group has historically determined the compensation for Fathom OpCo’s 2020 NEOs.

The 2020 compensation program for the NEOs consisted of base salary, short-term cash incentives, and long-term equity incentives, each as described below:

• Base Salary. Base salary is paid to attract and retain qualified talent and is set at a level that is commensurate with the executive’s duties and authorities, contributions, prior experience and sustained performance. Mr. Freeburg’s base salary was increased from $195,000 to $220,000 in June 2020; the other NEOs received a base salary increase in 2020.

• Short-Term Cash Incentives. Annual cash bonuses are paid under an annual cash incentive plan to incentivize the NEOs to achieve certain annual financial and operating performance metrics. Prior to the Reorganization, our NEOs’ annual cash bonuses were paid at the discretion of the board of managers of MCT Holdings. Following the Reorganization, annual cash bonus payments shall be made based on performance against annual financial targets and strategic goals subject to approval by the board of managers of Fathom OpCo. In 2020, Messrs. Martin and Stump had target bonus opportunities equal to an initial target of 40% of their base salaries, up to a maximum of 80% of their base salaries, and Mr. Freeburg had a target bonus opportunity equal to 40% of his base salary.

• Long-Term Equity Incentives. Historically, Fathom OpCo maintained the MCT Group Holdings, LLC 2019 Phantom Equity Bonus Plan (the “MCT Phantom Plan”) and the Incodema Holdings LLC 2020 Phantom Equity Bonus Plan (the “Incodema Phantom Plan”, together with the MCT Phantom Plan, the “Prior Phantom Plans”). The NEOs participated under the MCT Phantom Plan and were eligible to receive awards of phantom equity at the discretion of the board of managers of MCT Holdings. In 2020, no phantom equity awards were granted to the NEOs.

Phantom equity awarded to the NEOs under the MCT Phantom Plan was subject to the following vesting conditions: (i) 25% would vest subject to the NEO’s continued service with the MCT Group on each of the first four anniversaries of the NEO’s employment commencement date, and would be accelerated in connection with a change in control of MCT Holdings; and (ii) 75% would vest if MCT Holdings’ investors realized a multiple on invested capital equal to at least 2.0x in connection with a change in control of MCT Holdings. In connection with the Reorganization, the Prior Phantom Plans and all awards thereunder were terminated and replaced by a single phantom equity plan sponsored by Fathom OpCo and new awards thereunder, all of which contain terms and conditions that are substantially similar to the Prior Phantom Plans (the “Combined Phantom Plan”) and awards. The Combined Phantom Plan has a pool of phantom units equal to up to 10% of the total value receivable by common unit holders of Fathom OpCo on a sale of Fathom OpCo. Only 62.5% of the pool, or 6.25% of the total value receivable by common unit holders of Fathom OpCo on a sale of Fathom OpCo, has been granted.

The plan permits a discretionary match. In 2020, MCT provided eligible employees with matching contributions equal to 25% of a participant’s eligible 401(k) compensation, subject to limitations imposed under the Code.

As provided in the NEO’s phantom unit award agreements, the time-based vesting portion of the phantom unit award agreements would accelerate in connection with a change in control of MCT Holdings and the performance-based vesting portion of the phantom unit award agreements would vest if MCT Holdings investors realize a multiple of invested capital equal to at least 2.0x in connection with a change in control of MCT Holdings.

Post-Business Combination Company Executive Compensation

Following the completion of the Business Combination, Fathom intends to develop an executive compensation program that is designed to align compensation with Fathom’s business objectives and the creation of stockholder value, while enabling Fathom to attract, motivate and retain individuals who contribute to the long-term success of Fathom. Decisions on the executive compensation program will be made by the compensation committee of the board of directors.

In addition, following the consummation of the Business Combination, all vested time-based phantom unit awards under the Combined Phantom Plan outstanding immediately prior to the consummation of the Merger and held by individuals who are employed by or performing services for Fathom OpCo or its subsidiaries or affiliates as of the Closing, will be forfeited and cancelled and such holders shall receive grants of restricted shares of Fathom Class A Common Stock under the 2021 Omnibus Plan. The restricted shares shall not vest until the date the Form S-8 is filed registering the 2021 Omnibus Plan shares; provided, that, the vested, unrestricted shares of Fathom Class A common stock received in settlement of the restricted shares shall be subject to the following transfer restrictions: (i) 25% of the shares received may be traded upon the expiration of the lock-up period applicable to the shares of Fathom Class A common stock held by the CORE Investors and the CORE Affiliates; (ii) 25% of the shares received may be traded if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 60%; (iii) 25% of the shares received may be traded if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 80%; and (iv) 25% of the shares received may be traded if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 95% (the “Fathom Transfer Restrictions”).

271

In addition, following the consummation of the Business Combination, all unvested time-based phantom unit awards and performance-based phantom unit awards held by individuals who are employed by or performing services for Fathom OpCo or its subsidiaries or affiliates as of the Closing shall be forfeited and cancelled and such holders shall receive grants of restricted stock units (“RSUs”) with respect to Fathom Class A Common Stock under the 2021 Omnibus Plan, with time-based RSUs being granted to replace time-based phantom units and performance-based RSUs being granted to replace performance-based phantom units. The time-based vesting RSUs shall have the same vesting schedule as the time-based vesting units. Once a time-based RSU is vested, any share deliverable to the RSU holder will be subject to the Fathom Transfer Restrictions.

The performance-based vesting RSUs shall vest subject to the holder’s continued service through each of the following vesting events: (i) 25% of the RSUs will vest if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 60%; (ii) 25% of the RSUs will vest if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 80%; and (iii) 50% of the RSUs will vest if the CORE Investors and the CORE Affiliates collectively Sell-Down an Investor Cumulative Sale Percentage equal to at least 95%.

For purposes of this section, the following terms have the following meanings:

“CORE Investors” means CORE Industrial Partners Fund I, L.P., a Delaware limited partnership, CORE Industrial Partners Fund I Parallel, L.P., a Delaware limited partnership, CORE Fund I Holdings-2, L.P., a Delaware limited partnership, and CORE Fund I Holdings-5 LP, a Delaware limited partnership.

“CORE Affiliates” means, with respect to the CORE Investors, any person directly controlled by, directly controlling or under direct common control with the CORE Investors. For the avoidance of doubt, CORE Affiliates shall not include co-investors of the CORE Investors.

“Investor Cumulative Sale Percentage” means, on any date of determination, in the case of a Going Public Transaction, a percentage equal to the quotient of (A) a number equal to the aggregate number of shares of Fathom Class A common stock subject to a Sell-Down by the CORE Investors and the CORE Affiliates from and after the consummation of the Fathom OpCo’s Going Public Transaction and to and including such date, divided by (B) the aggregate number of shares of Fathom Class A common stock held by the CORE Investors and the CORE Affiliates upon the consummation of the Going Public Transaction and prior to any Sell-Down by the CORE Investors and the CORE Affiliates. The Investor Cumulative Sale Percentage may be adjusted to account for any stock splits, reverse stock splits, combinations, or similar structural changes to the shares of Fathom Class A common stock. For the avoidance of doubt, if, on the date of determination, the calculation of the Investor Cumulative Sale Percentage results in either the vesting of RSUs or the removal of certain restrictions on the transfer of shares of Fathom Class A common stock as described herein, then any release of any earn-out shares shall not negate the result of such vesting trigger being achieved or transfer restriction being removed.

“Going Public Transaction” means (i) the consummation of Fathom OpCo’s first underwritten Public Offering of its common stock under the Securities Act of 1933, as amended, or (ii) whether in one or a series of transactions, any merger, consolidation or other business combination pursuant to which the business of Fathom OpCo is combined with that of a special purpose acquisition company or other blank-check company that has a class of equity securities publicly listed on the New York Stock Exchange or Nasdaq.

“Public Offering” means the sale in an underwritten public offering registered under the Securities Act of equity securities of Fathom OpCo or a corporate successor to Fathom OpCo.

“Sell-Down” means, with respect to any person, (i) any sale by such person pursuant to a registered public offering under the Securities Act, and (ii) any sale by such person to the public pursuant to Rule 144 promulgated under the Securities Act effected through a broker, dealer or market maker (other than pursuant to Rule 144(b) prior to a Public Offering).

Board of Managers Compensation

As previously discussed above under the Background on Named Executive Officer Determination section, since the formation of Fathom OpCo and the Reorganization occurred in April 2021, Fathom OpCo’s non-employee managers for purposes of this disclosure are the members of the board of managers of both MCT Holdings and Incodema Holdings. The boards of managers for MCT Holdings and Incodema Holdings set non-employee manager compensation based on each manager’s prior experience. The compensation program is designed to provide competitive compensation necessary to attract and retain high quality non-employee managers and to encourage ownership of Fathom OpCo’s equity to further align their interests with those of its equityholders. As reflected below, Messrs. Chung, May, Puglisi, Papa and Rascia are ineligible to receive compensation for their service on the board of managers of MCT Holdings and/or Incodema Holdings, as each is serving on behalf of CORE Industrial Partners. Messrs. Nardelli and Chen, who served as non-employee managers of MCT Holdings, were eligible for the following compensation in connection with their role as managers:

• An annual cash retainer, the amount of which is based on the manager’s past experience, with Mr. Nardelli receiving $50,000 per year and Mr. Chen receiving $40,000 per year; and

• An initial phantom unit award consisting of units of MCT Holdings, subject to the following vesting conditions: (i) 25% would vest subject to the non-employee manager’s continued service with MCT Holdings or Incodema Holdings on each of the first four anniversaries of the non-employee manager’s board commencement date, and would be accelerated in connection with a change in control of MCT Holdings; and (ii) 75% would vest if MCT Holdings investors realized a multiple on invested capital equal to at least 2.0x in connection with a change in control of MCT Holdings. Messrs. Nardelli and Chen received initial grants of 500 phantom units and 250 phantom units of MCT Holdings, respectively, on January 1, 2020. Like the NEOs, members of the MCT Holdings and Incodema Holdings boards of managers with phantom awards under the Prior Phantom Plans had their awards terminated in connection with the Reorganization and received new awards under the Combined Phantom Plan.

As part of his board of managers’ compensation package, Mr. Nardelli was eligible to enter into a co-investment arrangement with the Company, described in more detail under “Fathom OpCo Related Person Transactions – Nardelli Investment.” In addition, in connection with his service as a manager of the board, Mr. Chen entered into a consulting agreement, dated August 3, 2020, with MCT Holdings, under which he provided consulting services to MCT Holdings to improve their operational processes in exchange for a monthly consulting fee of $3,333.33 per month (the “Chen Consulting Agreement”). Mr. Chen also served as Chief Executive Officer of the Incodema Group starting in August of 2020.

The same restrictions applicable to the restricted shares and RSUs granted to executive officer holders of phantom units following the Closing and described above under Post-Business Combination Company Executive Compensation generally will apply to Fathom’s go-forward non-employee directors who held phantom units in Fathom OpCo.

Executive Officers

The following persons are expected to be the executive officers of Fathom following the completion of the Business Combination:

Name	Position with Fathom	Age as of Special Meeting
Ryan Martin	Chief Executive Officer	42
Richard Stump	Chief Commercial Officer	41
Mark Frost	Chief Financial Officer	58

Biographical information for Messrs. Martin, Stump and Frost is set forth under “Management of Fathom OpCo Prior to the Business Combination.”

Board Composition

Our Proposed Charter and Proposed Bylaws provide for a classified board of directors consisting of three classes of directors, each serving staggered three-year terms, as follows:

Our Class I directors are Caralynn Nowinski Collens, Adam DeWitt and Ryan Martin, and their initial term will expire at the initial annual meeting of stockholders for the calendar year ended December 31, 2022.

Our Class II directors are Maria Green, Peter Leemputtee and Robert Nardelli, and their terms will expire at the annual meeting of stockholders for the calendar year ended December 31, 2023.

Our Class III directors are Carey Chen, TJ Chung, David Fisher and John May, and their terms will expire at the annual meeting of stockholders for the calendar year ended December 31, 2024.

Upon expiration of the term of a class of directors, directors for that class will be elected for three-year terms at the annual meeting of stockholders in the year in which that term expires. Each director’s term continues until the election and qualification of his or her successor or his or her earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of an equal number of directors.

In addition, in connection with the Business Combination, we entered into an investor rights agreement pursuant to which we granted to the CORE Investors the right to designate nominees to our Board of Directors subject to the maintenance of certain ownership requirements. See “Certain Relationships and Related Party Transactions—Investor Rights Agreement” for additional information.

Director Independence

NYSE listing standards require that a majority of the board of directors be independent, subject to the controlled company exception. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or any other individual having a relationship which in the opinion of the board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director.

Potential Controlled Company Exemption

Immediately following the completion of the Business Combination and assuming no redemption by Altimar II’s Public Shareholders, the CORE Investors are expected to beneficially own approximately 46.1% of our Class A common stock and Class B common stock, which will generally vote together as a single class on matters submitted to a vote of our stockholders, including the election of directors (or 63.7% assuming maximum

278

redemptions by Altimar II Public Shareholders and without counting the Backstop Shares as part of the CORE Investors’ pro forma ownership). If more than 50% of the voting power for the election of directors of Fathom is held by an individual, a group or another company, including the CORE Investors, Fathom would qualify as a “controlled company” under the NYSE listing requirements. If following the completion of the Business Combination, the CORE Investors control a majority of the voting power of our outstanding capital stock, Fathom would qualify as, and would expect to elect to be treated as, a “controlled company” under the NYSE listing standards and in such case would not be subject to the requirements that would otherwise require us to have: (i) a majority of “independent directors,” as defined under the listing standards of the NYSE; (ii) a nominating committee comprised solely of independent directors; (iii) compensation of our executive officers determined by a majority of the independent directors or a compensation committee comprised solely of independent directors; and (iv) director nominees selected, or recommended for the Board’s selection, either by a majority of the independent directors or a nominating committee comprised solely of independent directors.

Pursuant to the New York Stock Exchange listing standards, if following the completion of the Business Combination Fathom is categorized as a controlled company, Fathom will not be required to have a board of directors composed of a majority of independent directors. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or any other individual having a relationship which in the opinion of the board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director.

Compensation Committee Interlocks and Insider Participation

Following the consummation of the Business Combination, Fathom’s compensation committee will consist of Caralynn Nowinski Collens, David Fisher, Maria Green and Peter Leemputtee. None of the expected members of Fathom’s compensation committee has at any time been an officer or employee of Altimar II. None of Fathom’s executive officers currently serves, or in the past fiscal year has served, as a member of the board of directors or compensation committee (or other board committee performing equivalent functions or, in the absence of any such committee, the entire board of directors) of any entity that has one or more executive officers on Altimar II’s or Fathom’s compensation committee or board of directors. In certain circumstances, Fathom would qualify as, and would expect to elect to be treated as, a “controlled company” within the meaning of the NYSE listing standards. In such event, the composition of Fathom’s compensation committee may be modified and as a result, the composition of the committee might not be comprised solely of “independent directors” as defined under the listing standards of the NYSE.

Code of Business Conduct and Ethics

Effective upon the consummation of the Business Combination, Fathom will adopt a code of business conduct and ethics that will apply to all of its employees, officers and directors, including those officers responsible for financial reporting. The code of business conduct and ethics will be available after the Closing on Fathom’s website at www.                .com. Fathom expects that, to the extent required by law, any amendments to the code, or any waivers of its requirements, will be disclosed on its website.

Limitation on Liability and Indemnification Matters

Fathom’s certificate of incorporation that will become effective immediately following the consummation of the Business Combination and will contain provisions that limit the personal liability of Fathom’s directors for monetary damages to the fullest extent permitted by Delaware law. Consequently, Fathom’s directors will not be personally liable to Fathom or its stockholders arising from a breach of fiduciary duty as a director, unless:

• the presumption that directors are acting in good faith, on an informed basis, and with a view to the best interests of Fathom and its stockholders has been rebutted; and

• it is proven that the director’s act or failure to act constituted a breach of his or her fiduciary duties as a director and such breach involved intentional misconduct, a knowing violation of law or receipt of an improper personal benefit.

279

Post-Combination Company Executive Compensation

Overview

Following the closing of the Business Combination, we expect Fathom’s executive compensation program to be consistent with Fathom OpCo’s existing compensation policies and philosophies, which are designed to:

• attract, retain and motivate senior management leaders who are capable of advancing our mission and strategy and ultimately, creating and maintaining our long-term equity value. Such leaders must engage in a collaborative approach and possess the ability to execute our business strategy in an industry characterized by competitiveness and growth;

• reward senior management in a manner aligned with our financial performance; and

• align senior management’s interests with our equity owners’ long-term interests through equity participation and ownership.

Following the closing of the Business Combination, decisions with respect to the compensation of our executive officers will be made by the compensation committee of the board of directors of Fathom. The following discussion is based on the present expectations as to the compensation of our executive officers and directors following the Business Combination. The actual compensation of our executive officers will depend on the judgment of the members of the compensation committee of the board of directors of Fathom and may differ from that set forth in the following discussion.

We anticipate that compensation for our executive officers will have the following components: base salary, cash bonus opportunities, long-term incentive compensation, broad-based employee benefits, supplemental executive perquisites and severance benefits. These benefits will be designed to attract and retain senior management talent. We also expect to use annual cash bonuses and long-term equity awards to promote performance-based pay that aligns the interests of our executive officers with the long-term interests of our equity-owners and to enhance executive retention. At the time of this filing, no new employment agreements with any executive officers of Fathom are contemplated.

Base Salary

We expect that our executive officers’ base salaries in effect prior to the Business Combination will continue, subject to potential increases made in connection with the negotiation of any employment agreements or Fathom’s annual review of its executive officers’ base salaries. Following the Business Combination, our executive officers’ base salaries will be reviewed annually by the compensation committee of the board of directors of Fathom.

Annual Bonuses

We expect that Fathom will use annual cash incentive bonuses for the executive officers to motivate their achievement of short-term performance goals and tie a portion of their cash compensation to performance. We expect that, near the beginning of each year, the compensation committee of the board of directors of Fathom will select the performance targets, target amounts, target award opportunities and other terms and conditions of annual cash bonuses for the executive officers, subject to the terms of their employment agreements. Following the end of each year, the compensation committee of the Fathom board of directors will determine the extent to which the performance targets were achieved and the amount of the award that is payable to the executive officers.

Stock-Based Awards

We expect Fathom to use stock-based awards in future years as an incentive for executives to remain in our service and aligning the executives’ interests with those of Fathom’s equityholders. Any stock-based awards will

280

be awarded in future years under the 2021 Omnibus Plan. For a description of the 2021 Omnibus Plan, please see “Proposal No. 7 — The Equity Incentive Plan Proposal.”

Other Compensation

We expect Fathom to continue to maintain various employee benefit plans currently maintained by Fathom OpCo, including medical, dental, vision, life insurance and 401(k) plans, paid time off and holidays and employee assistance program benefits in which the executive officers will participate. We also expect Fathom to continue to provide its executive officers with specified perquisites and personal benefits currently provided by Fathom OpCo that are not generally available to all employees. For additional details, please see “Executive and Director Compensation of Fathom OpCo.”

In addition, to encourage employee stock ownership, we expect to offer employees an opportunity to participate in an employee stock purchase plan under the ESPP to align employee interests with those of Fathom’s stockholders, and to enhance the ability of Fathom to attract, motivate and retain qualified employees. An employee stock ownership plan will offer a convenient means for our employees who might not otherwise own our common stock to purchase and hold shares. For a description of the ESPP, please see “Proposal No. 8 - The ESPP Proposal.”

Director Compensation

Following the Business Combination, non-employee directors of Fathom will receive varying levels of compensation for their services as directors and members of committees of Fathom’s board of directors. Fathom anticipates determining non-employee director compensation in accordance with industry practice and standards. Altimar II and Fathom OpCo have agreed to an annual limit of $900,000 on non-employee director compensation with respect to the board of directors of Fathom; provided, that any Awards granted under the Plan or other compensation received by a non-employee director related to the settlement, conversion or substitution of the non-employee director’s award(s) under the Fathom Holdco, LLC Phantom Equity Bonus Plan (also referred to as the Combined Phantom Plan) shall not count against such limit.

Related Party Transaction Policy Following the Business Combination

Upon consummation of the Business Combination, Fathom will adopt a written related person transaction policy that sets forth the following policies and procedures for the review and approval or ratification of related person transactions.

A “Related Person Transaction” is a transaction, arrangement or relationship in which Fathom or any of its subsidiaries was, is or will be a participant, the amount of which involved exceeds $120,000, and in which any related person had, has or will have a direct or indirect material interest.

A “Related Person” means:

• any person who is, or at any time during the applicable period was, one of the Fathom’s officers or one of Fathom’s directors;

287

• any person who is known by Fathom to be the beneficial owner of more than five percent (5%) of its voting stock;

• any immediate family member of any of the foregoing persons, which means any child, stepchild, parent, stepparent, spouse, sibling, mother-in-law, father-in-law, daughter-in-law, brother-in-law or sister-in-law of a director, officer or a beneficial owner of more than five percent (5%) of its voting stock, and any person (other than a tenant or employee) sharing the household of such director, officer or beneficial owner of more than five percent (5%) of its voting stock; and

• any firm, corporation or other entity in which any of the foregoing persons is a partner or principal or in a similar position or in which such person has a ten percent (10%) or greater beneficial ownership interest.

Fathom will have policies and procedures designed to minimize potential conflicts of interest arising from any dealings it may have with its affiliates and to provide appropriate procedures for the disclosure of any real or potential conflicts of interest that may exist from time to time. Specifically, pursuant to its charter, the audit committee will have the responsibility to review related party transactions.

All of the transactions described in this section were entered into prior to the adoption of this policy. Certain of the foregoing disclosures are summaries of certain provisions of our related party agreements, and are qualified in their entirety by reference to all of the provisions of such agreements. Because these descriptions are only summaries of the applicable agreements, they do not necessarily contain all of the information that you may find useful. Copies of certain of the agreements (or forms of the agreements) have been filed as exhibits to the registration statement of which this prospectus is a part, and are available electronically on the website of the SEC at www.sec.gov..

Indemnification

Effective immediately upon the consummation of the Business Combination, we will enter into indemnification agreements with each of the newly elected directors and newly appointed executive officers which provide that we will indemnify such directors and executive officers under the circumstances and to the extent provided for therein, from and against all losses, claims, damages, liabilities, joint or several, expenses (including legal fees and expenses), judgments, fines, penalties, interest, settlements or other amounts arising from any and all threatened, pending or completed claim, demand, action, suit or proceeding, whether civil, criminal, administrative or investigative, and whether formal or informal, and including appeals, in which he or she may be involved, or is threatened to be involved, as a party or otherwise, to the fullest extent permitted under Delaware law and our by-laws.

On July 15, 2021, HPS Partners Holdings II, LLC, an affiliate of Sponsor, entered into an Original PIPE Subscription Agreement to subscribe for 1,000,000 shares of Class A common stock at a purchase price of $10,000,000.

On July 15, 2021, The Scott B. Kapnick 2016 Revocable Trust entered into an Original PIPE Subscription Agreement to subscribe for 1,000,000 shares of Class A common stock at a purchase price of $10,000,000.

For a detailed description of the Original PIPE Subscription Agreements, see the section entitled, “The Business Combination Agreement – Subscription Agreements.”

Other

On December 15, 2020, the Sponsor paid $25,000, or approximately $0.003 per share, to cover certain of Altimar II’s offering and formation costs in consideration of 8,625,000 Class B ordinary shares, par value $0.0001.

On January 28, 2021, the Sponsor transferred 25,000 founder shares to certain of Altimar II’s directors, namely Kevin L. Beebe, Payne D. Brown, Richard M. Jelinek, Roma Khanna, Michael Rubenstein, Vijay K. Sondhi and Michael Vorhaus, resulting in the Sponsor holding 8,450,000 Founder Shares. Up to 1,125,000 founder shares were subject to forfeiture by the Sponsor depending on the extent to which the underwriters exercised their over-allotment option in connection with Altimar II’s IPO. As a result of the underwriters’ election to fully exercise their over-allotment option on February 9, 2021, the 1,125,000 founder shares were not subject to forfeiture. The founder shares (including the Class A ordinary shares issuable upon exercise thereof) may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder.

The Sponsor purchased, pursuant to a written agreement, an aggregate of 9,900,000 Private Placement Warrants for a purchase price of $1.00 per whole warrant in a private placement that occurred concurrently with the closing of the IPO. Each private placement warrant entitles the holder to purchase one Class A ordinary share at $11.50 per share, subject to adjustment. The Private Placement Warrants (including the Class A ordinary shares issuable upon exercise thereof) may not, subject to certain limited exceptions, be transferred, assigned or sold by the holder until 30 days after the completion of an initial business combination.

Altimar II currently maintains its executive offices at 40 West 57th Street, 33rd Floor, New York, NY 10019. The cost for Altimar II’s use of this space is included in the $10,000 per month fee Altimar II pays to an affiliate of the Sponsor for office space and secretarial and administrative services. Upon completion of an initial business combination or Altimar II’s liquidation, Altimar II will cease paying these monthly fees.

No compensation of any kind, including finder’s and consulting fees, will be paid to the Sponsor, officers and directors, or their respective affiliates, for services rendered prior to or in connection with the completion of an initial business combination. However, these individuals will be reimbursed for any out-of-pocket expenses incurred in connection with activities on Altimar II’s behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Altimar II’s audit committee will review on a quarterly basis all payments that were made by Altimar II to the Sponsor, officers, directors or their affiliates and will determine which expenses and the amount of expenses that will be reimbursed. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on Altimar II’s behalf.

On December 15, 2020, Altimar II issued an unsecured promissory note (the “Promissory Note”) to the Sponsor, pursuant to which Altimar II could borrow up to an aggregate principal amount of $300,000. The Promissory Note was non-interest bearing and payable on the earlier of (i) December 31, 2021 and (ii) the completion of the IPO. The outstanding balance under the Promissory Note of $94,890 was repaid at the closing of the Initial Public Offering on February 9, 2021.

In addition, in order to finance transaction costs in connection with an intended initial business combination, the Sponsor or an affiliate of the Sponsor or certain of Altimar II’s officers and directors may, but are not obligated to, loan Altimar II funds as may be required (the “Working Capital Loans”). If Altimar II completes an initial business combination, it may repay such loaned amounts out of the proceeds of the Trust Account released to Altimar II. In the event that the initial business combination does not close, Altimar II may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from the Trust Account would be used for such repayment. Except for the foregoing, the terms of the Working Capital Loans, if any, have not been determined and no written agreements exist with respect to the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,000,000 of the Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the

289

Private Placement Warrants. As of December 31, 2020, there were no amounts outstanding under the Working Capital Loans. Altimar II does not expect to seek loans from parties other than the Sponsor, its affiliates or its management team as it does not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in the Trust Account.

In connection with the IPO, Altimar II entered into a registration and shareholder rights agreement pursuant to which our initial shareholders are entitled to certain registration rights with respect to the Private Placement Warrants, the warrants issuable upon conversion of working capital loans (if any) and the Class A ordinary shares issuable upon exercise of the foregoing and upon conversion of the founder shares, and, upon consummation of an initial business combination, to nominate three individuals for appointment to Altimar II’s board of directors, as long as the initial shareholders hold any securities covered by the registration and shareholder rights agreement. Altimar II will bear the expenses incurred in connection with the filing of any such registration statements.

Policy for Approval of Related Party Transactions

The audit committee of Altimar II’s board of directors has adopted a charter providing for the review, approval and/or ratification of “related party transactions,” which are those transactions required to be disclosed pursuant to Item 404 of Regulation S-K as promulgated by the SEC, by the audit committee. At its meetings, the audit committee shall be provided with the details of each new, existing, or proposed related party transaction, including the terms of the transaction, any contractual restrictions that Altimar II has already committed to, the business purpose of the transaction, and the benefits of the transaction to Altimar II and to the relevant related party. Any member of the committee who has an interest in the related party transaction under review by the committee shall abstain from voting on the approval of the related party transaction, but may, if so requested by the chairman of the committee, participate in some or all of the committee’s discussions of the related party transaction. Upon completion of its review of the related party transaction, the committee may determine to permit or to prohibit the related party transaction.

FATHOM INDEBTEDNESS

2021 Term Loan

On April 30, 2021, Fathom OpCo obtained a $172 million term loan (the “2021 Term Loan”) from JPMorgan Chase Bank, N.A., as lender and administrative agent for the other lenders from time to time party thereto (collectively, the “April 2021 Lenders’) in order to (i) finance its acquisitions of Centex Machine and Welding, Inc., Laser Manufacturing, Inc., Sureshot Precision, LLC d/b/a MicropulseWest, and Precision Process Corporation, and (ii) refinance Fathom OpCo’s then outstanding long-term debt. The 2021 Term Loan is due for repayment on April 29, 2022.

The interest rate per annum applicable to 2021 Term Loan is, at the option of Fathom OpCo, equal to either an alternate base rate (“ABR Loans”) or an adjusted LIBO rate for a one-, two-, three-, six- or twelve month interest period (“LIBO Loans”), in each case plus an applicable margin. The alternate base rate, means the greatest of (i) JPMorgan Chase Bank, N.A.’s prime rate, (ii) one-half of 1% over the weighted average of rates on overnight Federal Funds as published by the Federal Reserve Bank of New York, (iii) the adjusted LIBO rate for a one month interest period and (iv) 1%. The adjusted LIBO rate is determined by reference to settlement rates established for deposits in the currency of the applicable borrowing in the London or European interbank market for a period equal to the interest period of the applicable loan and the maximum reserve percentages established by the Board of Governors of the U.S. Federal Reserve to which the administrative agent is subject.    The applicable margin with respect to any portion of the 2021 Term Loan comprised of ABR Loans ranges from 2.50% to 3.00% depending on the gross leverage ratio, subject to prospective adjustment on a quarterly basis. The applicable margin with respect to any portion of the 2021 Term Loan comprised of LIBO Loans ranges from 3.50% to 4.00% depending on the gross leverage ratio, subject to prospective adjustment on a quarterly basis.

Additionally, the applicable margin with respect to the 2021 Term Loan is subject to step ups of 100 percentage points for each period of 90 days that the 2021 Term Loan remains outstanding after the initial draw date thereof (with such step-up component capping out a 400 percentage points in the aggregate). As of the date of this proxy statement/prospectus, the per annum rate of interest applicable to the entire 2021 Term Loan is the adjusted LIBO rate for a 3-month interest period. Additionally, the principal amount outstanding under the 2021 Term Loan as of September 30, 2021 was $170 million and there was no availability for further drawdowns under the facility.

The 2021 Term Loan was undertaken as bridge financing while Fathom OpCo sought to identify and complete a significant capital transaction such as the Business Combination that would enable Fathom OpCo to obtain long-term refinancing of its debt on commercially reasonable terms. If Fathom OpCo is unable to complete a significant capital transaction such as the Business Combination prior to April 9, 2022, and obtain funding of the credit facilities provided for under the New Credit Agreement described below, it expects that it would not have sufficient funds on hand and from cash flow from operations to repay the 2021 Term Loan when it matures on April 29, 2022. The Business Combination Agreement and the Closing are subject to customary closing conditions, some of which as is typical are out of Fathom OpCo’s control and, as a consequence, there can be no guarantee that the Business Combination and the funding of the New Credit Agreement will be completed. Accordingly, Grant Thornton LLP, Fathom OpCo’s independent registered public accounting firm/independent certified public accountants, included a going concern emphasis paragraph in its audit report covering the audited financial statements of Fathom OpCo included in this proxy statement/prospectus. See “Risk Factors – Risks Related to the Business Combination and Altimar II –The audit report we received with respect to our audited financial statements for the years ended December 31, 2020 and December 31, 2019 included emphasis of a matter regarding going concern. We must raise additional capital before April 29, 2022 to refinance our debt, and funding of the credit facilities provided for under our New Credit Agreement for this purpose is conditioned upon the completion of the Business Combination.”

291

New Credit Agreement

On July 9, 2021, Fathom OpCo agreed to enter into a new credit agreement (the “New Credit Agreement”) with JPMorgan Chase Bank, N.A. and certain other lenders (the “New Lenders”) which, when funded, will provide a $50 million revolving credit facility and a $125 million term loan. The proceeds from the New Credit Agreement will be used to repay the 2021 Term Loan. The loans to be made under the New Credit Agreement will mature in 2026. Funding of loans under the New Credit Agreement is conditioned upon Fathom OpCo completing a business combination with a publicly traded special purpose acquisition company, such as the Business Combination with Altimar II, before April 9, 2022 (the “SPAC Transaction”). In addition, funding of the loans under the New Credit Agreement is further conditioned on the cash proceeds of the SPAC Transaction being in excess of $313 million (or a lesser amount if mutually agreed by Fathom OpCo and Altimar II) of which not less than $30 million shall be contributed to Fathom OpCo to repay certain indebtedness and to fund balance sheet cash.

The revolving credit facility under the New Credit Agreement will be available for working capital and other general corporate purposes and will include a letter of credit sub-facility of up to $5 million. The New Credit Agreement will also include an uncommitted incremental facility, which, subject to certain conditions, will provide for additional term loan facilities, an increase in commitments under the New Credit Agreement and/or an increase in commitments under the revolving credit facility, in an aggregate amount of up to $100 million.

Fathom OpCo’s obligations under the New Credit Agreement will be guaranteed by Fathom OpCo and its subsidiaries, subject to certain exceptions. Loans under the New Credit Agreement will be secured by substantially all of the tangible and intangible assets of Fathom OpCo and the guarantors under the New Credit Agreement, subject to permitted liens and certain exceptions. Fathom OpCo and its subsidiaries will be subject under the New Credit Agreement to customary affirmative and negative covenants, including limitations on their ability to incur additional indebtedness and engage in certain business transactions, such as distributions and other restricted payments, acquisitions and other investments and mergers. In addition, the New Credit Agreement contains two financial maintenance covenants, which will require Fathom OpCo to (1) comply with a maximum Net Leverage Ratio (as defined in the New Credit Agreement) and (2) maintain a minimum Interest Coverage Ratio (as defined in the New Credit Agreement). Events of default under the New Credit Agreement include, among other things, nonpayment of principal when due, nonpayment of interest, fees or other amounts after a grace period, material inaccuracy of representations and warranties, violation of covenants (subject, in the case of certain affirmative covenants, to a grace period) cross-event of default to material debt, bankruptcy events, certain ERISA events, default under uninsured material judgments, certain changes of control, actual or asserted invalidity of the New Credit Agreement and non-perfection of the security interest on any material portion of the collateral. If an event of default occurs under the New Credit Agreement, after the expiration of any applicable cure period, the New Lenders will be permitted to declare all outstanding borrowings under the New Credit Agreement immediately due and payable. If the New Credit Agreement is funded, there can be no guarantee that Fathom OpCo will be able to maintain compliance with all covenants under the New Credit Facility in the future and, if Fathom OpCo fails to comply with any such covenants, that waivers from the New Lenders will be obtained.

292

DESCRIPTION OF FATHOM’S CAPITAL STOCK

The following summary of certain provisions of Fathom’s capital stock does not purport to be complete and is subject to the Proposed Charter, the Proposed Bylaws, the Investor Rights Agreement and the provisions of applicable law. Copies of the Proposed Charter, the Proposed Bylaws and the Investor Rights Agreement are attached to this proxy statement/prospectus as Annex A, Annex B and Annex E, respectively.

Authorized Capitalization

General

The Proposed Charter will authorize the issuance of 500,000,000 shares of capital stock, par value $0.0001 per share, of Fathom, consisting of:

• 300,000,000 shares of Class A common stock,

The following summary describes all material provisions of our capital stock. We urge you to read the Proposed Charter, the Proposed Bylaws and the Investor Rights Agreement (copies of which are attached to this proxy statement/prospectus as Annex A, Annex B and Annex E, respectively).

Common Stock

Class A common stock

We expect to have approximately 135,063,750 shares of Class A common stock outstanding immediately after the consummation of the Business Combination, assuming that none of Altimar II’s outstanding Class A ordinary shares are redeemed in connection with the Business Combination. The 135,063,750 shares of Class A common stock includes (i) 8,000,000 shares of Class A common stock issued as part of the PIPE investment, (ii) 4,770,000 shares of Class A common stock resulting from the conversion of the Altimar II Founders’ Class B ordinary shares into Class C common stock as part of the Business Combination and subsequent automatic conversion into shares of Class A common stock and pro rata forfeiture by the Altimar II Founders of the Forfeited Shares, (iii) the conversion of Altimar II’s 34,500,000 shares of Class A ordinary shares into 34,500,000 shares of Class A common stock and (iv) 87,793,750 shares of Class A common stock issued as part of the merger consideration contemplated by the Business Combination Agreement. The 135,063,750 shares of Class A common stock excludes (i) the Sponsor Earnout, (ii) the Earnout and (iii) Class A common stock underlying the Public Warrants and the Private Placement Warrants.

We expect to have approximately 135,063,750 shares of Class A common stock outstanding immediately after the consummation of the Business Combination, assuming the maximum redemptions scenario described in this proxy statement/prospectus. The 135,063,750 shares of Class A common stock includes (i) 9,000,000 shares of Class A common stock issued pursuant to the PIPE Subscription Agreements, including the Backstop Agreement, (ii) 4,770,000 shares of Class A common stock resulting from the conversion of the Altimar II Founders’ Class B ordinary shares into Class C common stock as part of the Business Combination and subsequent automatic conversion into shares of Class A common stock and pro rata forfeiture by the Altimar II Founders of the Forfeited Shares, and (iii) 121,293,750 shares of Class A common stock issued as part of the merger consideration contemplated by the Business Combination Agreement. The 135,063,750 shares of Class A common stock excludes (i) the Sponsor Earnout, (ii) the Earnout and (iii) Class A common stock underlying the Public Warrants and the Private Placement Warrants.

Voting rights. Each holder of Class A common stock is entitled to one vote for each share of Class A common stock held of record by such holder on all matters on which stockholders generally are entitled to vote. Holders of Class A common stock will vote together with the holders of Class B common stock and Class C

293

common stock as a single class on all matters presented to the Company’s stockholders for their vote or approval. Generally, subject to the Investor Rights Agreement and except for certain matters requiring supermajority approval by the Proposed Charter as described below under “ — Supermajority Approval Requirements,” all matters to be voted on by stockholders must be approved by a majority (or, in the case of election of directors, by a plurality) of the votes entitled to be cast by all stockholders present in person or represented by proxy, voting together as a single class. Stockholders do not have the ability to cumulate votes for the election of directors. The Proposed Charter provides for a classified board of directors consisting of three classes of approximately equal size, each serving staggered three-year terms. Only one class of directors will be elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms.

Notwithstanding the foregoing, to the fullest extent permitted by law, holders of common stock, as such, will have no voting power with respect to, and will not be entitled to vote on, any amendment to the Proposed Charter (including any certificate of designations relating to any series of preferred stock) that relates solely to the terms of one or more outstanding series of preferred stock, if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to the Proposed Charter (including any certificate of designations relating to any series of preferred stock) or pursuant to the DGCL.

Dividend Rights. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of shares of Class A common stock will be entitled to receive ratably such dividends, if any, as may be declared from time to time on Common Stock having dividend rights by our board of directors out of funds legally available therefor.

Rights upon liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs, the holders of Class A common stock will be entitled to share ratably in all assets remaining after payment of Fathom’s debts and other liabilities, subject to pari passu and prior distribution rights of preferred stock or any class or series of stock having a preference over the Class A common stock, then outstanding, if any.

Other rights. Except as provided in the Investor Rights Agreement (as applicable), the holders of Class A common stock will have no preemptive or conversion rights or other subscription rights. There will be no redemption or sinking fund provisions applicable to the Class A common stock. The rights, preferences and privileges of holders of the Class A common stock will be subject to those of the holders of any shares of the preferred stock the Company may issue in the future and to the Investor Rights Agreement, as applicable.

Subject to the transfer and exchange restrictions set forth in the Fathom Operating Agreement, holders of Fathom OpCo Units may exchange these units for shares of our Class A common stock, on a one-for-one basis or, at the election of an exchange committee of Fathom OpCo, for cash. When a Fathom OpCo Unit is exchanged, a corresponding share of our Class B common stock, depending on the holder, will automatically be transferred to us and retired for no consideration.

Class B common stock

Upon completion of the Business Combination, and assuming that none of Altimar II’s outstanding Class A ordinary shares are redeemed in connection with the Business Combination, we expect there to be approximately 67,489,588 shares of our Class B common stock outstanding (including shares of Class B common stock corresponding to the portion of Earnout Shares issued initially in the form of New Fathom Units and subject to vesting and forfeiture events). Shares of Class B common stock will be issued to Continuing Fathom Unitholders who are receiving New Fathom Units (i) in connection with the Business Combination and (ii) upon the occurrence of a Triggering Event with respect to a Seller Earnout Unit (as determined pursuant to the formulation and definition described under “The Business Combination Agreement—Earnout”). All shares of Class B common stock to be issued in connection with the Business Combination will be fully paid and non-assessable. There is no trading market for the Class B common stock.

294

Voting Rights. Holders of our Class B common stock will be entitled to one vote for each share held of record on all matters submitted to a vote of stockholders. Following the consummation of the Business Combination, holders of Class B common stock will vote together with holders of Class A common stock and Class C common stock as a single class on all matters presented to Fathom’s stockholders for their vote or approval, except as otherwise required by the Proposed Charter and applicable law.

Dividend Rights. Holders of the Class B common stock will not be entitled to dividends in respect of their shares of Class B common stock.

Rights upon liquidation. The holders of shares of Class B common stock, as such, shall not be entitled to receive any assets of Fathom in the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs. We refer to the Class B common stock as “vote-only” shares.

Redemption of Class B common stock for Class A common stock. Shares of Class B common stock are redeemable for shares of Class A common stock on the terms and subject to the conditions set forth in the Fathom Operating Agreement. The Company may satisfy its or its affiliates’ obligations in respect of any redemption of shares of Class B common stock under the Fathom Operating Agreement by delivering (either directly or indirectly through an affiliate) to the holder of shares of Class B common stock upon such redemption, in lieu of newly issued shares of Class A common stock, cash in the amount permitted by and provided in the Fathom Operating Agreement or shares of Class A common stock which are held in the treasury of Fathom. All shares of Class A common stock that may be issued upon any such redemption will, upon issuance in accordance with the Fathom Operating Agreement, be validly issued, fully paid and non-assessable. All shares of Class B common stock so redeemed for Class A common stock shall be cancelled.

Other rights. Except as provided in the Investor Rights Agreement (as applicable), the holders of Class B common stock will have no preemptive or other subscription rights. The rights, preferences and privileges of holders of the Class B common stock will be subject to those of the holders of any shares of the preferred stock Fathom may issue in the future and to the Investor Rights Agreement, as applicable.

Issuance and Transfer. There will be no further issuances of Class B common stock except in connection with (i) a stock split, stock dividend, reclassification or similar transaction, (ii) an issuance of Fathom OpCo Units or (iii) a Triggering Event occurring with respect to a Seller Earnout Unit. When a Fathom OpCo Unit is exchanged pursuant to the Fathom Operating Agreement, a corresponding share of our Class B common stock will automatically be transferred to us and retired for no consideration. Class B common stock is not transferable unless a corresponding number of Fathom OpCo Units are simultaneously transferred to the same person.

Class C common stock

Upon the effectiveness of the Domestication, there will be 8,625,000 shares of our Class C common stock outstanding resulting from the conversion of a like number of Class B ordinary shares. Upon consummation of the Business Combination, all remaining shares of Class C common stock then outstanding will automatically convert into shares of Class A common stock prior to pro rata forfeiture by the Altimar II Founders of an aggregate of 2,587,500 shares of Class A common stock pursuant to the Forfeiture and Support Agreement as described herein, and no further shares of Class C common stock will thereafter be issued.

Voting rights. Holders of our Class C common stock will be entitled to one vote for each share held of record on all matters submitted to a vote of stockholders.

Dividend Rights. Subject to preferences that may be applicable to any outstanding preferred stock, the holders of shares of Class C common stock will be entitled to receive ratably such dividends, if any, as may be declared from time to time on Common Stock having dividend rights by our board of directors out of funds legally available therefor.

295

Rights upon liquidation. In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs, the holders of Class C common stock will be entitled to share ratably in all assets remaining after payment of the Company’s debts and other liabilities, subject to prior distribution rights of preferred stock or any class or series of stock having a preference over the Class C common stock, then outstanding, if any.

Conversion into Class A common stock. Shares of Class C common stock automatically convert into shares of Class A common stock on a one-for-one basis (the “Initial Conversion Ratio”) (a) at any time and from time to time at the option of the holder thereof; and (b) automatically on the day of the closing of a business combination. Notwithstanding the Initial Conversion Ratio, if additional shares of Class A common stock or any other equity-linked securities, are issued or deemed issued in excess of the number offered in the IPO and related to the closing of a business combination, the ratio at which the outstanding shares of Class C common stock convert into shares of Class A common stock is adjusted (unless the holders of a majority of the outstanding shares of Class C common stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all outstanding shares of Class C common stock will equal, in the aggregate, 20% of the sum of all shares of Class A ordinary shares and Class B ordinary shares outstanding upon completion of the IPO plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with such business combination, excluding any shares or equity-linked securities issued, or to be issued, to any seller in a such business combination.

Under the terms of the Forfeiture and Support Agreement, Sponsor agreed that, from and after the Closing, 1,267,500 shares of Altimar II Class B ordinary shares (or, following the Domestication, shares of Class C common stock or Class A common stock, as applicable) held by Sponsor (other than any shares of Altimar II common stock issued to Sponsor pursuant to the PIPE Investment) (the “Sponsor Earnout Shares”) will be unvested and restricted and that such shares will vest automatically if (a) the VWAP of the Altimar II Class A Common Stock equals or exceeds $12.50 per share for any twenty (20) trading days within a period of thirty (30) consecutive trading days and (b) there is a change of control of Altimar II, unless the per share consideration to be received by the holders of Class A common stock in such change of control transaction is less than the vesting threshold applicable to the Sponsor Earnout Shares (each of (a) and (b), a “Vesting Event”). To the extent that, on or prior to the fifth (5th) anniversary of the Closing Date, a Vesting Event did not occur, all outstanding unvested Sponsor Earnout Shares will automatically be forfeited. In addition, pursuant to the Forfeiture and Support Agreement and the Business Combination Agreement, the Altimar II Founders also agreed that, effective upon and subject to the consummation of the Business Combination, they will irrevocably automatically forfeit and surrender, for no additional consideration and without any further action on the part of any other person, the Forfeited Shares.

Other rights. The holders of Class C common stock will have no preemptive or conversion rights or other subscription rights. There will be no redemption or sinking fund provisions applicable to the Class C common stock. The rights, preferences and privileges of holders of the Class C common stock will be subject to those of the holders of any shares of the preferred stock the Company may issue in the future.

Preferred Stock

No shares of preferred stock will be issued or outstanding immediately after the completion of the Business Combination. The Proposed Charter will authorize the board of directors to establish one or more series of preferred stock in one or more classes or series and to fix the rights, preferences, privileges and related restrictions, including dividend rights, dividend rates, conversion rights, voting rights, the right to elect directors, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any class or series, or the designation of the class or series, without the approval of our stockholders.

296

The authority of our board of directors to issue preferred stock without approval of our stockholders may have the effect of delaying, deferring or preventing a change in control of Fathom and may adversely affect the voting and other rights of the holders of our common stock. The issuance of preferred stock with voting and conversion rights may adversely affect the voting power of the holders of our common stock, including the loss of voting control to others. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of the Class A common stock. At present, we have no plans to issue any preferred stock.

Authorized but Unissued Capital Stock

Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of The New York Stock Exchange, which would apply so long as the Class A common stock remains listed on the New York Stock Exchange, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of Class A common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings, to raise additional capital or to facilitate acquisitions.

One of the effects of the existence of unissued and unreserved common stock or preferred stock may be to enable our board of directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of our company by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management and possibly deprive the stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

Anti-Takeover Effects of Provisions of Delaware Law and the Proposed Charter and Proposed Bylaws

Certain provisions of Charter and Proposed Bylaws could discourage potential acquisition proposals and could delay or prevent a change in control. These provisions are intended to enhance the likelihood of continuity and stability in the composition of our board of directors and in the policies formulated by our board of directors and to discourage certain types of transactions that may involve an actual or threatened change of control. These provisions are designed to reduce our vulnerability to an unsolicited acquisition proposal or proxy fight. Such provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they also may inhibit fluctuations in the market price of our Class A common stock that could result from actual or rumored takeover attempts. Such provisions also may have the effect of preventing changes in our management or delaying or preventing a transaction that might benefit you or other minority stockholders.

These provisions include:

No Action by Written Consent; Special Meetings of Stockholders. The DGCL permits stockholder action by written consent unless otherwise provided by our certificate of incorporation. The Proposed Charter precludes holders of Common Stock from taking action by written consent. If permitted by the applicable certificate of designation, future series of preferred stock may take action by written consent. The Proposed Charter and the Proposed Bylaws provide that special meetings of stockholders may be called (i) only by the board of directors or the chairman of the board of directors pursuant to a written resolution adopted by the affirmative vote of the number of directors equal to a majority of the board assuming no vacancies or (ii) prior to the date on which CORE and its affiliates cease to beneficially own in the aggregate (directly or indirectly) at least 25% of the then outstanding Common Stock, by the chairman of the board of directors at the written request of holders of at least a majority of the then outstanding Common Stock. Further, any business transacted at any special meeting of stockholders is limited to the purpose or purposes included in the notice may be considered at such special meeting.

Election and Removal of Directors. The DGCL provides that stockholders are not entitled to the right to cumulate votes in the election of directors unless the certificate of incorporation provides otherwise. The

297

Proposed Charter does not expressly provide for cumulative voting. Directors may be removed, but only for cause (and subject to the Investor Rights Agreement), upon the affirmative vote of holders of 66-2/3% of the voting power of the outstanding shares of our capital stock entitled to vote generally in the election of directors, voting together as a single class. In addition, the certificate of designation pursuant to which a particular series of preferred stock is issued may provide holders of that series of preferred stock with the right to elect additional directors. In addition, under the Proposed Charter, our board of directors is divided into three classes of directors, each of which will hold office for a three-year term. The existence of a classified board could delay a successful tender offeror from obtaining majority control of our board of directors, and the prospect of that delay might deter a potential offeror.

Supermajority Approval Requirements. The Proposed Charter and Proposed Bylaws provide that our Board is expressly authorized to make, alter, amend, change, add to, rescind or repeal, in whole or in part, the Proposed Bylaws without a stockholder vote in any matter not inconsistent with the laws of the State of Delaware and the Proposed Charter. In addition, any amendment, alteration, change, addition, rescission or repeal of the Proposed Bylaws by our stockholders will require the affirmative vote of holders of 66-2/3% in voting power of the outstanding shares of our stock entitled to vote on such amendment, alteration, change, addition, rescission or repeal.

The DGCL provides generally that the affirmative vote of a majority of the outstanding shares entitled to vote thereon, voting together as a single class, is required to amend a corporation’s certificate of incorporation, unless the certificate of incorporation requires a greater percentage. The Proposed Charter provides that the following provisions in the Proposed Charter may be amended, altered, repealed or rescinded only by the affirmative vote of the holders of at least 66-2/3% (or, 80%, for the provision indicated below) in voting power of all the then-outstanding shares of stock of Fathom entitled to vote thereon, voting together as a single class:

• the provision requiring a 66-2/3% supermajority vote for stockholders to amend the Proposed Bylaws;

• the provisions providing for the manner of establishing the size of the board and for a classified board (the election and term of our directors);

• the provisions regarding resignation and removal of directors;

• the provisions regarding entering into business combinations with interested stockholders (requiring at least an 80% supermajority vote);

• the provisions precluding stockholder action by written consent;

• the provisions regarding calling special meetings of stockholders;

• the provisions regarding filling vacancies on our Board and newly created directorships;

• the provisions regarding the establishment of Delaware as the exclusive forum for certain types of legal proceedings against Fathom, its directors, officers and employees;

• the provisions eliminating monetary damages for breaches of fiduciary duty by a director; and

• the amendment provision requiring that the above provisions be amended only with a 66-2/3% supermajority vote.

The combination of the classification of our Board, the lack of cumulative voting and the supermajority voting requirements will make it more difficult for our existing stockholders to replace our Board as well as for another party to obtain control of us by replacing our Board. Because our Board has the power to retain and discharge our officers, these provisions could also make it more difficult for existing stockholders or another party to effect a change in management.

Authorized but Unissued Shares. The authorized but unissued shares of common stock and preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the listing

298

rules of The New York Stock Exchange. The existence of authorized but unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise. See “Description of Fathom’s Capital Stock—Preferred Stock” and “Description of Fathom’s Capital Stock—Authorized but Unissued Capital Stock” above.

Business Combinations with Interested Stockholders. In general, Section 203 of the DGCL, an anti-takeover law, prohibits a publicly held Delaware corporation from engaging in a business combination, such as a merger, with a person or group owning 15% or more of the corporation’s voting stock, which person or group is considered an interested stockholder under the DGCL, for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the business combination or the transaction in which the person became an interested stockholder is approved in a prescribed manner.

We elected in the Proposed Charter not to be subject to Section 203.

Other Limitations on Stockholder Actions. The Proposed Bylaws also impose some procedural requirements on stockholders who wish to:

• make nominations in the election of directors;

• propose that a director be removed; or

• propose any other business to be brought before an annual or special meeting of stockholders.

Under these procedural requirements, in order to bring a proposal before a meeting of stockholders, a stockholder must deliver timely notice of a proposal pertaining to a proper subject for presentation at the meeting to our corporate secretary containing, among other things, the following:

• the stockholder’s name and address;

• the number of shares beneficially owned by the stockholder and evidence of such ownership;

• the names of all persons with whom the stockholder is acting in concert and a description of all arrangements and understandings with those persons;

• a description of any agreement, arrangement or understanding reached with respect to shares of our stock, such as borrowed or loaned shares, short positions, hedging or similar transactions;

• a description of the business or nomination to be brought before the meeting and the reasons for conducting such business at the meeting; and

• any material interest of the stockholder in such business.

The Proposed Bylaws set out the timeliness requirements for delivery of notice.

In order to submit a nomination for our board of directors, a stockholder must also submit any information with respect to the nominee that we would be required to include in a proxy statement, as well as some other information. If a stockholder fails to follow the required procedures, the stockholder’s proposal or nominee will be ineligible and will not be voted on by our stockholders.

Limitations on Liability and Indemnification of Officers and Directors

The Proposed Charter and Proposed Bylaws provide indemnification for our directors and officers to the fullest extent permitted by the DGCL. We plan to enter into indemnification agreements with each of our directors and executive officers that may, in some cases, be broader than the specific indemnification provisions contained under Delaware law. In addition, as permitted by Delaware law, the Proposed Charter includes provisions that eliminate the personal liability of our directors for monetary damages resulting from breaches of certain fiduciary duties as a director. The effect of this provision is to restrict our rights and the rights of our

299

stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duties as a director, except that a director will be personally liable for:

• any breach of his duty of loyalty to us or our stockholders;

• acts or omissions not in good faith, or which involve intentional misconduct or a knowing violation of law;

• unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; or

• any transaction from which the director derived an improper personal benefit.

These provisions may be held not to be enforceable for violations of the federal securities laws of the United States.

Exclusive Forum

The Proposed Charter will provide that, unless the Company consents in writing to the selection of an alternative forum, (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of the Company to the Company or the Company’s stockholders, or any claim for aiding and abetting such alleged breach, (iii) any action asserting a claim against the Company or any current or former director, officer, other employee, agent or stockholder of the Company (a) arising pursuant to any provision of the DGCL, the Proposed Charter (as it may be amended or restated) or the Proposed Bylaws or (b) as to which the DGCL confers jurisdiction on the Delaware Court of Chancery or (iv) any action asserting a claim against the Company or any current or former director, officer, other employee, agent or stockholder of the Company governed by the internal affairs doctrine of the law of the State of Delaware shall, as to any action in the foregoing clauses (i) through (iv), to the fullest extent permitted by law, be solely and exclusively brought in the Delaware Court of Chancery; provided, however, that the foregoing shall not apply to any claim (a) as to which the Delaware Court of Chancery determines that there is an indispensable party not subject to the jurisdiction of the Delaware Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten days following such determination), (b) which is vested in the exclusive jurisdiction of a court or forum other than the Delaware Court of Chancery, or (c) arising under federal securities laws, including the Securities Act of 1933, as amended, as to which the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum. Notwithstanding the foregoing, the provisions of Article XI of the Proposed Charter will not apply to suits brought to enforce any liability or duty created by the Exchange Act, or any other claim for which the federal district courts of the United States of America shall be the sole and exclusive forum. Further, Section 22 of the Securities Act of 1933 creates concurrent jurisdiction for federal and state courts over all suits brought to enforce any duty or liability created by that act or the rules and regulations thereunder. Accordingly, there is uncertainty as to whether a court would enforce this forum selection provision as written as to claims arising under the Securities Act. Any person or entity purchasing or otherwise acquiring any interest in any shares of the Company’s capital stock shall be deemed to have notice of and to have consented to the forum provisions in the Proposed Charter. If any action the subject matter of which is within the scope of the forum provisions is filed in a court other than a court located within the State of Delaware (a “foreign action”) in the name of any stockholder, such stockholder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of Delaware in connection with any action brought in any such court to enforce the forum provisions (an “enforcement action”); and (y) having service of process made upon such stockholder in any such enforcement action by service upon such stockholder’s counsel in the foreign action as agent for such stockholder. However, it is possible that a court could find the Company’s forum selection provisions to be inapplicable or unenforceable. Although the Company believes this provision benefits it by providing increased consistency in the application of Delaware law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuits against the Company’s directors, officers and other employees.

Stockholder Registration Rights

Under the terms of the Registration Rights Agreement, Fathom granted to the Legacy Fathom Owners, Sponsor and certain other former Altimar II equityholders customary demand, shelf and piggyback registration rights. Fathom is required to file within thirty days of the Closing a shelf registration statement registering the public resale of the shares of common stock of Fathom (“Shelf Registration Statement”), and cause the Shelf Registration Statement to be declared effective as promptly as practicable after the filing thereof and no later than the earlier of (A) 60 calendar days after the filing thereof (or, in the event the SEC reviews and has written comments to the Shelf Registration Statement, the 90th calendar day following the filing thereof) and (B) the 10th business day after the date Fathom is notified (orally or in writing, whichever is earlier) by the SEC that it will not review the Shelf Registration Statement. See “Certain Relationships and Related Party Transactions — Fathom Related Person Transactions — Registration Rights Agreement.” The PIPE Investors also have been granted certain, customary registration rights pursuant to the Original PIPE Subscription Agreements and the CORE Backstop Agreement.

Warrants

Public Shareholders’ Warrants. Each whole warrant entitles the registered holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed below, at any time commencing on the later of one year from the closing of the IPO and 30 days after the completion of our initial business combination, except as discussed in the immediately succeeding paragraph. Pursuant to the warrant agreement, a warrant holder may exercise its warrants only for a whole number of Class A ordinary shares. This means only a whole warrant may be exercised at a given time by a warrant holder. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. The warrants will expire five years after the completion of our initial business combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

We will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to our satisfying our obligations described below with respect to registration, or a valid exemption from registration is available. No warrant will be exercisable and we will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will we be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the Class A ordinary share underlying such unit.

We have agreed that as soon as practicable, but in no event later than 20 business days after the closing of our initial business combination, we will use our commercially reasonable efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, and we will use our commercially reasonable efforts to cause the same to become effective within 60 business days following the closing of our initial business combination, and to maintain the effectiveness of such registration statement and a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement; provided that if our Class A ordinary shares are at the time of any exercise of a public warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, we may, at our option, require holders of public warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event we so elect, we will not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, but we will use our commercially reasonably efforts to register or qualify for sale the shares under applicable blue sky laws to the extent an exemption is not available. If a

301

registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60th day after the closing of the initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when we will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a) (9) of the Securities Act or another exemption, but we will use our commercially reasonably efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available. In such event, each holder would pay the exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” (defined below) over the exercise price of the warrants by (y) the fair market value and (B) 0.361 per warrant. The “fair market value” as used in this paragraph shall mean the volume weighted average price of the Class A ordinary shares for the 10 trading days ending on the trading day prior to the date on which the notice of exercise is received by the warrant agent.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00

Once the warrants become exercisable, we may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and

• if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading “ —Warrants—Public Shareholders’ Warrants—Anti-Dilution Adjustments”) for any twenty (20) trading days within a thirty (30)-trading day period ending on the third trading day prior to the date on which we send the notice of redemption to the warrant holders.

We will not redeem the warrants as described above unless a registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants is then effective and a current prospectus relating to those Class A ordinary shares is available throughout the 30-day redemption period. If and when the warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws.

If we call the warrants for redemption as described above, our management will have the option to require all holders that wish to exercise warrants to do so on a “cashless basis.” In determining whether to require all holders to exercise their warrants on a “cashless basis,” our management will consider, among other factors, our cash position, the number of warrants that are outstanding and the dilutive effect on our shareholders of issuing the maximum number of Class A ordinary shares issuable upon the exercise of our warrants. In such event, each holder would pay the exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the lesser of (A) the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the excess of the “fair market value” of our Class A ordinary shares over the exercise price of the warrants by (y) the fair market value and (B) 0.361 per warrant.

We have established the last of the redemption criterion discussed above to prevent a redemption call unless there is at the time of the call a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and we issue a notice of redemption of the warrants, each warrant holder will be entitled to exercise his, her or its warrant prior to the scheduled redemption date. Any such exercise would not be done on a “cashless” basis and would require the exercising warrant holder to pay the exercise price for each warrant being exercised. However, the price of the Class A ordinary shares may fall below the $18.00 redemption trigger price (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading “—Warrants—Public Shareholders’ Warrants—Anti-Dilution Adjustments”) as well as the $11.50 (for whole shares) warrant exercise price after the redemption notice is issued.

302

Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00

Once the warrants become exercisable, we may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

• in whole and not in part;

• at $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined by reference to the table below, based on the redemption date and the “fair market value” of our Class A ordinary shares (as defined below) except as otherwise described below; and

• if, and only if, the closing price of our Class A ordinary shares equals or exceeds $10.00 per public share (as adjusted for adjustments to the number of shares issuable upon exercise or the exercise price of a warrant as described under the heading “ — Warrants—Public Shareholders’ Warrants—Anti-Dilution Adjustments”) on the trading day prior to the date on which we send the notice of redemption to the warrant holders.

Beginning on the date the notice of redemption is given until the warrants are redeemed or exercised, holders may elect to exercise their warrants on a cashless basis. The numbers in the table below represent the number of Class A ordinary shares that a warrant holder will receive upon such cashless exercise in connection with a redemption by us pursuant to this redemption feature, based on the “fair market value” of our Class A ordinary shares on the corresponding redemption date (assuming holders elect to exercise their warrants and such warrants are not redeemed for $0.10 per warrant), determined for these purposes and in “—Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00” above based on volume weighted average price of our Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants, and the number of months that the corresponding redemption date precedes the expiration date of the warrants, each as set forth in the table below. We will provide our warrant holders with the final fair market value no later than one business day after the 10-trading day period described above ends.

Pursuant to the warrant agreement, references above to Class A ordinary shares shall include a security other than Class A ordinary shares into which the Class A ordinary shares have been converted or exchanged for in the event we are not the surviving company in our initial business combination. The numbers in the table below will not be adjusted when determining the number of Class A ordinary shares to be issued upon exercise of the warrants if we are not the surviving entity following our initial business combination.

The share prices set forth in the column headings of the table below will be adjusted as of any date on which the number of shares issuable upon exercise of a warrant or the exercise price of a warrant is adjusted as set forth under the heading “— Anti-Dilution Adjustments” below. If the number of shares issuable upon exercise of a warrant is adjusted, the adjusted share prices in the column headings will equal the share prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the exercise price of the warrant after such adjustment and the denominator of which is the exercise price of the warrant immediately prior to such adjustment. In such an event, the number of shares in the table below shall be adjusted by multiplying such share amounts by a fraction, the numerator of which is the number of shares deliverable upon exercise of a warrant immediately prior to such adjustment and the denominator of which is the number of shares deliverable upon exercise of a warrant as so adjusted. If the exercise price of a warrant is adjusted, (a) in the case of an adjustment pursuant to the fifth paragraph under the heading “— Anti-Dilution Adjustments” below, the adjusted share prices in the column headings will equal the unadjusted share price multiplied by a fraction, the numerator of which is the higher of the Market Value and the Newly Issued Price as set forth under the heading “— Anti-Dilution Adjustments” and the denominator of which is $10.00 and (b) in the case of an adjustment pursuant to the second paragraph under the heading “— Anti-Dilution Adjustments” below, the adjusted share prices in the column

303

headings will equal the unadjusted share price less the decrease in the exercise price of a warrant pursuant to such exercise price adjustment.

The exact fair market value and redemption date may not be set forth in the table above, in which case, if the fair market value is between two values in the table or the redemption date is between two redemption dates in the table, the number of Class A ordinary shares to be issued for each warrant exercised will be determined by a straight-line interpolation between the number of shares set forth for the higher and lower fair market values and the earlier and later redemption dates, as applicable, based on a 365 or 366-day year, as applicable. For example, if the volume weighted average price of our Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the warrants is $11.00 per share, and at such time there are 57 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.277 Class A ordinary shares for each whole warrant. For an example where the exact fair market value and redemption date are not as set forth in the table above, if the volume weighted average price of our Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the warrants is $13.50 per share, and at such time there are 38 months until the expiration of the warrants, holders may choose to, in connection with this redemption feature, exercise their warrants for 0.298 Class A ordinary shares for each whole warrant. In no event will the warrants be exercisable on a cashless basis in connection with this redemption feature for more than 0.361 Class A ordinary shares per warrant (subject to adjustment). Finally, as reflected in the table above, if the warrants are out of the money and about to expire, they cannot be exercised on a cashless basis in connection with a redemption by us pursuant to this redemption feature, since they will not be exercisable for any Class A ordinary shares.

This redemption feature differs from the typical warrant redemption features used in many other blank check offerings, which typically only provide for a redemption of warrants for cash (other than the Private Placement Warrants) when the trading price for the Class A ordinary shares exceeds $18.00 per share for a specified period of time. This redemption feature is structured to allow for all of the outstanding warrants to be redeemed when the Class A ordinary shares are trading at or above $10.00 per public share, which may be at a

304

time when the trading price of our Class A ordinary shares is below the exercise price of the warrants. We have established this redemption feature to provide us with the flexibility to redeem the warrants without the warrants having to reach the $18.00 per share threshold set forth above under “ — Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00.” Holders choosing to exercise their warrants in connection with a redemption pursuant to this feature will, in effect, receive a number of shares for their warrants based on an option pricing model with a fixed volatility input as of this proxy statement/prospectus. This redemption right provides us with an additional mechanism by which to redeem all of the outstanding warrants, and therefore have certainty as to our capital structure as the warrants would no longer be outstanding and would have been exercised or redeemed. We will be required to pay the applicable redemption price to warrant holders if we choose to exercise this redemption right and it will allow us to quickly proceed with a redemption of the warrants if we determine it is in our best interest to do so. As such, we would redeem the warrants in this manner when we believe it is in our best interest to update our capital structure to remove the warrants and pay the redemption price to the warrant holders.

As stated above, we can redeem the warrants when the Class A ordinary shares are trading at a price starting at $10.00, which is below the exercise price of $11.50, because it will provide certainty with respect to our capital structure and cash position while providing warrant holders with the opportunity to exercise their warrants on a cashless basis for the applicable number of shares. If we choose to redeem the warrants when the Class A ordinary shares are trading at a price below the exercise price of the warrants, this could result in the warrant holders receiving fewer Class A ordinary shares than they would have received if they had chosen to wait to exercise their warrants for Class A ordinary shares if and when such Class A ordinary shares were trading at a price higher than the exercise price of $11.50.

No fractional Class A ordinary shares will be issued upon exercise. If, upon exercise, a holder would be entitled to receive a fractional interest in a share, we will round down to the nearest whole number of the number of Class A ordinary shares to be issued to the holder. If, at the time of redemption, the warrants are exercisable for a security other than the Class A ordinary shares pursuant to the warrant agreement (for instance, if we are not the surviving company in our initial business combination), the warrants may be exercised for such security. At such time as the warrants become exercisable for a security other than the Class A ordinary shares, the Company (or surviving company) will use its commercially reasonable efforts to register under the Securities Act the security issuable upon the exercise of the warrants.

Redemption Procedures

A holder of a warrant may notify us in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to the warrant agent’s actual knowledge, would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of the Class A ordinary shares issued and outstanding immediately after giving effect to such exercise.

Anti-Dilution Adjustments

If the number of outstanding Class A ordinary shares is increased by a capitalization or share dividend payable in Class A ordinary shares, or by a split-up of ordinary shares or other similar event, then, on the effective date of such capitalization or share dividend, split-up or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding ordinary shares. A rights offering made to all or substantially all holders of ordinary shares entitling holders to purchase Class A ordinary shares at a price less than the “historical fair market value” (as defined below) will be deemed a share dividend of a number of Class A ordinary shares equal to the product of (i) the number of Class A ordinary shares actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for Class A ordinary shares) and (ii) one minus the quotient of (x) the price per Class A ordinary share paid in such rights offering and (y) the historical fair market

305

value. For these purposes, (i) if the rights offering is for securities convertible into or exercisable for Class A ordinary shares, in determining the price payable for Class A ordinary shares, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “historical fair market value” means the volume weighted average price of Class A ordinary shares as reported during the 10 trading day period ending on the trading day prior to the first date on which the Class A ordinary shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if we, at any time while the warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities or other assets to all or substantially all of the holders of the Class A ordinary shares on account of such Class A ordinary shares (or other securities into which the warrants are convertible), other than (a) as described above, (b) any cash dividends or cash distributions which, when combined on a per share basis with all other cash dividends and cash distributions paid on the Class A ordinary shares during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed $0.50 (as adjusted to appropriately reflect any other adjustments and excluding cash dividends or cash distributions that resulted in an adjustment to the exercise price or to the number of Class A ordinary shares issuable on exercise of each warrant) but only with respect to the amount of the aggregate cash dividends or cash distributions equal to or less than $0.50 per share, (c) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a proposed initial business combination, (d) to satisfy the redemption rights of the holders of Class A ordinary shares in connection with a shareholder vote to amend our Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of our obligation to provide holders of our Class A ordinary shares the right to have their shares redeemed in connection with our initial business combination or to redeem 100% of our public shares if we do not complete our initial business combination within 24 months from the closing of the IPO or (B) with respect to any other provision relating to the rights of holders of our Class A ordinary shares, or (e) in connection with the redemption of our public shares upon our failure to complete our initial business combination, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each Class A ordinary share in respect of such event.

If the number of outstanding Class A ordinary shares is decreased by a consolidation, combination, reverse share sub-division or reclassification of Class A ordinary shares or other similar event, then, on the effective date of such consolidation, combination, reverse share subdivision, reclassification or similar event, the number of Class A ordinary shares issuable on exercise of each warrant will be decreased in proportion to such decrease in outstanding Class A ordinary shares.

Whenever the number of Class A ordinary shares purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of Class A ordinary shares purchasable upon the exercise of the warrants immediately prior to such adjustment and (y) the denominator of which will be the number of Class A ordinary shares so purchasable immediately thereafter.

In addition, if (x) we issue additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of our initial business combination at an issue price or effective issue price of less than $9.20 per ordinary share (with such issue price or effective issue price to be determined in good faith by our board of directors and, in the case of any such issuance to our initial shareholders or their respective affiliates, without taking into account any founder shares held by our initial shareholders or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of our initial business combination on the date of the consummation of our initial business combination (net of redemptions), and (z) the volume weighted average trading price of our Class A ordinary shares during the 20 trading day period starting on the trading day after the day on which we consummate our initial business combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be

306

adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share redemption trigger price described above under “—Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00” and “—Redemption of warrants when the price per Class A ordinary shares equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price described above under “—Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00” will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

In case of any reclassification or reorganization of the outstanding Class A ordinary shares (other than those described above or that solely affects the par value of such Class A ordinary shares), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which we are the continuing corporation and that does not result in any reclassification or reorganization of our outstanding Class A ordinary shares), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which we are dissolved, the holders of the warrants will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the Class A ordinary shares immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of Class A ordinary shares or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised their warrants immediately prior to such event. However, if such holders were entitled to exercise a right of election as to the kind or amount of securities, cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets for which each warrant will become exercisable will be deemed to be the weighted average of the kind and amount received per share by such holders in such consolidation or merger that affirmatively make such election, and if a tender, exchange or redemption offer has been made to and accepted by such holders (other than a tender, exchange or redemption offer made by the company in connection with redemption rights held by shareholders of the company as provided for in our Amended and Restated Memorandum and Articles of Association or as a result of the redemption of Class A ordinary shares by the company if a proposed initial business combination is presented to the shareholders of the company for approval) under circumstances in which, upon completion of such tender or exchange offer, the maker thereof, together with members of any group (with-in the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning of Rule 13d-3 under the Exchange Act) more than 50% of the issued and outstanding Class A ordinary shares, the holder of a warrant will be entitled to receive the highest amount of cash, securities or other property to which such holder would actually have been entitled as a shareholder if such warrant holder had exercised the warrant prior to the expiration of such tender or exchange offer, accepted such offer and all of the Class A ordinary shares held by such holder had been purchased pursuant to such tender or exchange offer, subject to adjustment (from and after the consummation of such tender or exchange offer) as nearly equivalent as possible to the adjustments provided for in the warrant agreement. If less than 70% of the consideration receivable by the holders of Class A ordinary shares in such a transaction is payable in the form of Class A ordinary shares in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within thirty days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the warrant agreement based on the Black-Scholes value (as defined in the warrant agreement) of the warrant. The purpose of such exercise price reduction is to provide additional value to holders of the warrants when an extraordinary transaction occurs during the exercise period of the warrants pursuant to which the holders of the warrants otherwise do not receive the full potential value of the warrants.

307

The warrants were issued in registered form under a warrant agreement between Continental Stock Transfer & Trust Company, as warrant agent, and us. The warrant agreement provides that the terms of the warrants may be amended without the consent of any holder for the purpose of (i) curing any ambiguity or correct any mistake, including to conform the provisions of the warrant agreement to the description of the terms of the warrants and the warrant agreement set forth in this prospectus, or defective provision (ii) amending the provisions relating to cash dividends on ordinary shares as contemplated by and in accordance with the warrant agreement or (iii) adding or changing any provisions with respect to matters or questions arising under the warrant agreement as the parties to the warrant agreement may deem necessary or desirable and that the parties deem to not adversely affect the rights of the registered holders of the warrants, provided that the approval by the holders of at least 50% of the then-outstanding public warrants is required to make any change that adversely affects the interests of the registered holders. A copy of the warrant agreement, which was filed as an exhibit to the registration statement for the IPO, contains a complete description of the terms and conditions applicable to the warrants.

The warrant holders do not have the rights or privileges of holders of ordinary shares and any voting rights until they exercise their warrants and receive Class A ordinary shares. After the issuance of Class A ordinary shares upon exercise of the warrants, each holder will be entitled to one vote for each share held of record on all matters to be voted on by shareholders.

No fractional warrants will be issued upon separation of the units and only whole warrants will trade. If, upon exercise of the warrants, a holder would be entitled to receive a fractional interest in a share, we will, upon exercise, round down to the nearest whole number the number of Class A ordinary shares to be issued to the warrant holder.

We have agreed that, subject to applicable law, any action, proceeding or claim against us arising out of or relating in any way to the warrant agreement will be brought and enforced in the courts of the State of New York or the United States District Court for the Southern District of New York, and we irrevocably submit to such jurisdiction, which jurisdiction will be the exclusive forum for any such action, proceeding or claim. This provision applies to claims under the Securities Act but does not apply to claims under the Exchange Act or any claim for which the federal district courts of the United States of America are the sole and exclusive forum.

Private Placement Warrants. Except as described below, the Private Placement Warrants have terms and provisions that are identical to those of the warrants sold as part of the units in the IPO. The Private Placement Warrants (including the Class A common stock issuable upon exercise of the Private Placement Warrants) will not be transferable, assignable or salable until 30 days after the completion of our initial business combination (except pursuant to limited exceptions to our officers and directors and other persons or entities affiliated with the initial purchasers of the Private Placement Warrants) and they will not be redeemable by us so long as they are held by the Sponsor or its permitted transferees. Sponsor, or its permitted transferees, has the option to exercise the Private Placement Warrants on a cashless basis. If the Private Placement Warrants are held by holders other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by us in all redemption scenarios and exercisable by the holders on the same basis as the warrants included in the units being sold in the IPO. Any amendment to the terms of the Private Placement Warrants or any provision of the warrant agreement with respect to the Private Placement Warrants will require a vote of holders of at least 50% of the number of the then outstanding Private Placement Warrants.

If holders of the Private Placement Warrants elect to exercise them on a cashless basis, they would pay the exercise price by surrendering his, her or its warrants for that number of Class A common stock equal to the quotient obtained by dividing (x) the product of the number of Class A common stock underlying the warrants, multiplied by the excess of the “Sponsor fair market value” (defined below) over the exercise price of the warrants by (y) the Sponsor fair market value. For these purposes, the “Sponsor fair market value” means the average reported closing price of the Class A common stock for the 10 trading days ending on the third trading day prior to the date on which the notice of warrant exercise is sent to the warrant agent. The reason that Altimar II agreed that these warrants will be exercisable on a cashless basis so long as they are held by the Sponsor and

308

its permitted transferees is because it was not known at the time of the IPO whether they will be affiliated with us following a business combination. If they remain affiliated with us, their ability to sell our securities in the open market will be significantly limited. We have policies in place that restrict insiders from selling our securities except during specific periods of time. Even during such periods of time when insiders are permitted to sell our securities, an insider cannot trade in our securities if he or she is in possession of material non-public information. Accordingly, unlike public shareholders who could exercise their warrants and sell the Class A common stock received upon such exercise freely in the open market in order to recoup the cost of such exercise, the insiders could be significantly restricted from selling such securities. As a result, we believe that allowing the holders to exercise such warrants on a cashless basis is appropriate.

In order to fund working capital deficiencies or finance transaction costs in connection with an intended initial business combination by Altimar II, the Sponsor or an affiliate of the Sponsor or certain of Altimar II’s officers and directors may, but are not obligated to, loan us funds as may be required. Up to $2,000,000 of such loans may be convertible into warrants of Fathom at a price of $1.00 per warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants.

Transfer Agent, Warrant Agent and Registrar

The transfer agent and registrar for the Fathom common stock and the warrant agent for the Fathom public warrants and Private Placement Warrants will be Continental Stock Transfer and Trust Company.

Listing

We intend to list our Class A common stock and our warrants to purchase Class A common stock on The New York Stock Exchange under the symbols “FATH” and “FATH.WS,” respectively.

309

SECURITIES ACT RESTRICTIONS ON RESALE OF CLASS A COMMON STOCK

Rule 144

Pursuant to Rule 144 under the Securities Act (“Rule 144”), a person who has beneficially owned restricted common stock or warrants of Fathom for at least six months would be entitled to sell their securities provided that (i) such person is not deemed to have been one of our affiliates at the time of, or at any time during the three months preceding, a sale and (ii) we are subject to the Exchange Act periodic reporting requirements for at least three months before the sale and have filed all required reports under Section 13 or 15(d) of the Exchange Act during the 12 months (or such shorter period as we were required to file reports) preceding the sale.

Persons who have beneficially owned restricted common stock or warrants of Fathom for at least six months but who are our affiliates at the time of, or at any time during the three months preceding, a sale, would be subject to additional restrictions, by which such person would be entitled to sell within any three-month period only a number of securities that does not exceed the greater of:

• 1% of the total number of shares of Fathom common stock then outstanding (as of the date of this proxy statement/prospectus, Altimar II has                  ordinary shares outstanding); or

• the average weekly reported trading volume of Fathom common stock during the four calendar weeks preceding the filing of a notice on Form 144 with respect to the sale.

Sales by our affiliates under Rule 144 are also limited by manner of sale provisions and notice requirements and to the availability of current public information about us.

Restrictions on the Use of Rule 144 by Shell Companies or Former Shell Companies

Rule 144 is not available for the resale of securities initially issued by shell companies (other than business combination-related shell companies) or issuers that have been at any time previously a shell company. However, Rule 144 also includes an important exception to this prohibition if the following conditions are met:

• the issuer of the securities that was formerly a shell company has ceased to be a shell company;

• the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act;

• the issuer of the securities has filed all Exchange Act reports and material required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such reports and materials), other than Form 8-K reports; and

• at least one year has elapsed from the time that the issuer filed current Form 10 type information with the SEC reflecting its status as an entity that is not a shell company.

As a result, our initial shareholders will be able to sell their founder shares and Private Placement Warrants, as applicable, pursuant to Rule 144 without registration one year after we have completed the Business Combination.

We anticipate that following the consummation of the Business Combination, we will no longer be a shell company, and so, once the conditions set forth in the exceptions listed above are satisfied, Rule 144 will become available for the resale of the above noted restricted securities.

NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Altimar Acquisition Corp. II (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on December 7, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”). The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of September 30, 2021, the Company had not commenced any operations. All activity for the period from December 7, 2020 (inception) through September 30, 2021 relates to the Company’s formation, the Company’s initial public offering (the “Initial Public Offering”) which is described below, subsequent to the completion of the Initial Public Offering, identifying a target company for a Business Combination, and activities in connection with the proposed business combination with Fathom Holdco, LLC (see Note 6). The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Registration Statement on Form S-1 (File No. 333-252260) (the “Registration Statement”) for the Initial Public Offering was declared effective on February 4, 2021. On February 9, 2021, the Company consummated the Initial Public Offering of 34,500,000 units (the “Units” and, with respect to the Class A Ordinary Shares and the warrants included in the Units, the “Public Shares” and the “Public Warrants,” respectively), which includes the full exercise by the underwriters of their over-allotment option in the amount of 4,500,000 Units, at $10.00 per Unit, generating gross proceeds of $345,000,000, as described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 9,900,000 warrants (the “Private Placement Warrants” and, together with the Public Warrants, the “Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to Altimar Sponsor II, LLC (the “Sponsor”), generating gross proceeds of $9,900,000, as described in Note 4.

Transaction costs amounted to $19,490,958, consisting of $6,900,000 of underwriting fees, $12,075,000 of deferred underwriting fees (see Note 6) and $515,958 of other offering costs. $755,071 of the transaction costs was expensed through the condensed statement of operation on the date of the Initial Public Offering. The remaining transaction costs were charged to equity. 

Following the closing of the Initial Public Offering on February 9, 2021, an amount of $345,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Warrants was placed in a trust account (the “Trust Account”) and will be invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all

of the net proceeds are intended to be applied generally toward consummating a Business Combination. The New York Stock Exchange listing rules require that the Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (excluding the amount of deferred underwriting commissions and taxes payable on the income earned on the Trust Account) at the time of the signing a definitive agreement in connection with the initial Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to complete a Business Combination successfully.

The Company will provide the holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two business days prior to the consummation of the Business Combination (initially anticipated to be $10.00 per Public Share), including interest (which interest shall be net of taxes payable), divided by the number of the then issued and outstanding Public Shares, subject to certain limitations as described in the Registration Statement. The per-Public Share amount to be distributed to the Public Shareholders who properly redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters in the Initial Public Offering (as discussed in Note 6). There will be no redemption rights in connection with a Business Combination with respect to the Warrants.

The Company will not redeem Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 (so that it does not then become subject to the U.S. Securities and Exchange Commission’s (the “SEC”) “penny stock” rules) or any greater net tangible asset or cash requirement that may be contained in the agreement relating to the Business Combination. If the Company seeks shareholder approval of the Business Combination, the Company will proceed with a Business Combination only if the Company receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the ordinary shares represented in person or by proxy and entitled to vote thereon and who vote at a general meeting, or such other vote as required by applicable law or stock exchange rules. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to the Company’s amended and restated memorandum and articles of association (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the SEC and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote the Founder Shares (as defined below) and any Public Shares purchased during or after the Initial Public Offering in favor of approving a Business Combination. Additionally, the Public Shareholders may elect to redeem their Public Shares without voting and, if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in

concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its Public Shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

Each of the Sponsor and the Company’s executive officers and directors have agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with a Business Combination and (b) not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination prior to February 9, 2023 (the “Combination Period”) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-Public Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the amount on deposit in the Trust Account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares.

The Company will have until February 9, 2023 to consummate a Business Combination. However, if the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned and not previously released to the Company to pay taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of the then issued and outstanding Public Shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Public Shareholders and its board of directors, liquidate and dissolve, subject, in each case, to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares held by the Sponsor if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of its affiliates acquires Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company fails to complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the offering price per Unit ($10.00).

In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.00 per Public Share and (2) the actual amount per Public Share held

in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share, due to reductions in the value of trust assets, in each case, net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party that executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriters in the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

NOTE 1A. RESTATEMENT OF PREVIOUSLY ISSUED FINANCIAL STATEMENTS

In connection with the preparation of the Company’s unaudited interim condensed financial statements as of September 30, 2021, management determined it should restate its previously reported unaudited interim condensed financial statements. The Company had previously determined the Class A Ordinary Shares subject to possible redemption to be equal to the redemption value of $10.00 per Class A Ordinary Shares while also taking into consideration a redemption cannot result in net tangible assets being less than $5,000,001. Management has also determined that the Class A Ordinary Shares issued in connection with the Initial Public Offering can be redeemed or become redeemable subject to the occurrence of future events considered outside the Company’s control. Therefore, management has concluded that the redemption value should include all the Class A Ordinary Shares subject to possible redemption, resulting in the Class A Ordinary Shares subject to possible redemption being equal to their redemption value. In connection with the change in presentation for the Class A Ordinary Shares subject to possible redemption, the Company also restated its earnings per share calculation to allocate net income (loss) pro rata to Class A and Class B Ordinary Shares. The presentation contemplates a Business Combination as the most likely outcome, in which case, both the Class A Ordinary Shares and the Class B Ordinary Shares share pro rata in the income (loss) of the Company. 

In accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” and SEC Staff Accounting Bulletin No. 108, “Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements,” the Company evaluated the changes and has determined that the related impact was material to the previously filed financial statements that contained the error, reported in the Company’s Form 10-Qs for the quarterly periods ended March 31, 2021 and June 30, 2021 as well as the audited balance sheet reported in the Current Report on Form 8-K filed as of February 9, 2021, the closing date of the Initial Public Offering (collectively, the “Prior Affected Periods”). Therefore, the Company, in consultation with its Audit Committee, concluded that the Prior Affected Periods should be restated to present all Class A Ordinary Shares subject to possible redemption in temporary equity and to recognize accretion from the initial book value to redemption value at the time of its Initial Public Offering as well as to restate net income (loss) per share. As such, the Company is reporting these restatements to the Prior Affected Periods.

There has been no change in the Company’s total assets, liabilities or operating results.

The accompanying unaudited condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to the Quarterly Report on Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in condensed financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all of the information and footnotes necessary for a complete presentation of financial position, results of operations or cash flows. In the opinion of the Company’s management, the accompanying unaudited condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, results of operations and cash flows for the periods presented.

The interim results for the three and nine months ended September 30, 2021 are not necessarily indicative of the results to be expected for the year ending December 31, 2021 or for any future periods.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), and may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies, including, among others, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a registration statement under the Securities Act declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is

irrevocable. The Company has elected not to opt out of such extended transition period which means that, when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of the condensed financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed financial statements and the reported amounts of revenues and expenses during the reporting period.

Making estimates requires the Company’s management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed financial statements, which the Company’s management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

One of the more significant accounting estimates included in these condensed financial statements is the determination of the fair value of the warrant liability. Such estimates may be subject to change as more current information becomes available and accordingly the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. As of September 30, 2021 the Company held $345,011,697 in a money market fund in the Trust Account. The Company did not have any cash equivalents as of December 31, 2020.

Offering Costs

Offering costs consist of legal, accounting and underwriting fees and other costs incurred through the balance sheet date that are directly related to the Initial Public Offering. Offering costs amounted to $19,490,958, of which $18,735,887 were charged to Class A Ordinary Shares subject to possible redemption upon the completion of the Initial Public Offering and $755,071 were expensed on the condensed statement of operations.

Class A Ordinary Shares Subject to Possible Redemption

The Company accounts for the Class A Ordinary Shares subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” Class A Ordinary Shares subject to mandatory redemption are classified as a liability instrument and are measured at fair value. Conditionally redeemable Class A Ordinary Shares (including Class A Ordinary Shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A Ordinary Shares are classified as shareholders’ equity. The Class A Ordinary Shares feature

F-14

ALTIMAR ACQUISITION CORP. II

NOTES TO CONDENSED FINANCIAL STATEMENTS

September 30, 2021

(Unaudited)

certain redemption rights that are considered to be outside of the Company’s control and subject to occurrence of uncertain future events. Accordingly, as of September 30, 2021 and December 31, 2020, 34,500,000 and zero, respectively, Class A Ordinary Shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ equity section of the Company’s condensed balance sheets.

The Company recognizes changes in redemption value immediately as they occur and adjusts carrying value of redeemable Ordinary Shares to equal the redemption value at the end of the reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of the redeemable Class A Ordinary Shares resulted in charges against additional paid-in capital and accumulated deficit.

At September 30, 2021 the Class A Ordinary Shares reflected in the condensed balance sheet are reconciled in the following table:

Gross proceeds	$	345,000,000
Plus / (less) adjustments to carrying value:
Proceeds allocated to the Public Warrants		(12,933,516	)
Class A Ordinary Shares issuance costs		(18,735,887	)
Plus:
Accretion of carrying value to redemption value		31,669,403
Class A Ordinary Shares subject to possible redemption	$	345,000,000

Warrant Liability

The Company accounts for the Warrants as either equity-classified or liability-classified instruments based on an assessment of the Warrants’ specific terms and applicable authoritative guidance in the Financial Accounting Standards Board (the “FASB”) ASC Topic 480, “Distinguishing Liabilities from Equity,” and ASC Topic 815, “Derivatives and Hedging.” The assessment considers whether the Warrants are freestanding financial instruments pursuant to ASC Topic 480, whether Warrants meet the definition of a liability pursuant to ASC Topic 480 and whether the Warrants meet all of the requirements for equity classification under ASC Topic 815, including whether the Warrants are indexed to the Class A Ordinary Shares, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of issuance of the Warrants and as of each subsequent quarterly period end date while the Warrants are outstanding.

For issued or modified Warrants that meet all of the criteria for equity classification, the Warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified Warrants that do not meet all the criteria for equity classification, the Warrants are required to be recorded at their fair value on the date of issuance and each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss on the statements of operations. The fair value of the Public Warrants was determined using the closing price of the Public Warrants, and the fair value of the Private Placement Warrants was estimated using a Monte Carlo simulation approach (see Note 9).

Income Taxes

The Company accounts for income taxes under ASC Topic 740, “Income Taxes,” which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax

F-15

ALTIMAR ACQUISITION CORP. II

NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of September 30, 2021 and December 31, 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented.

Net Income (Loss) per Ordinary Share

The Company complies with accounting and disclosure requirements of ASC Topic 260, “Earnings Per Share.” The Company has two classes of ordinary shares, which are referred to as Class A Ordinary Shares and Class B Ordinary Shares. Income and losses are shared pro rata between the two classes of ordinary shares.

Net income (loss) per ordinary share is computed by dividing net income (loss) by the weighted average number of ordinary shares outstanding for the period. The calculation of diluted income (loss) per share does not consider the effect of the Public Warrants issued in connection with the Initial Public Offering and the sale of the Private Placement Warrants, because the exercise of the Warrants is contingent upon the occurrence of future events. Accretion associated with the redeemable shares of the Class A Ordinary Shares is excluded from earnings per share as the redemption value approximates fair value.

The following table reflects the calculation of basic and diluted net income (loss) per ordinary share (in dollars, except per share amounts):

	Three Months Ended September 30, 2021		Nine Months Ended September 30, 2021
Redeemable Class A Ordinary Shares
Numerator:
Allocation of net income (loss)	$	2,082,014	$	587,479
Denominator:
Basic and diluted weighted average shares outstanding		34,500,000		29,571,429
Basic and diluted net income (loss) per share	$	0.06	$	0.02
Class B Ordinary Shares
Numerator:
Allocation of net income (loss)	$	520,503	$	168,073
Denominator:
Basic and diluted weighted average shares outstanding		8,625,000		8,460,165
Basic and diluted net income (loss) per share	$	0.06	$	0.02

For the three and nine months ended September 30, 2021, basic and diluted shares are the same as there are no redeemable and non-redeemable securities that are dilutive to the Company’s shareholders.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which at times may exceed the Federal Depository Insurance Corporation coverage limit of $250,000. The Company has not experienced losses on these accounts and the Company’s management believes the Company is not exposed to significant risks on such account.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying condensed balance sheets, primarily due to their short-term nature, except for the warrant liability (see Note 9).

Recent Accounting Standards

In August 2020, the FASB issued Accounting Standards Update No. 2020-06, ”Debt — Debt with Conversion and Other Options (Subtopic 470-20)” and “Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity” (“ASU 2020-06”), which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. ASU 2020-06 removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception and it also simplifies the diluted earnings per share calculation in certain areas. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2020-06 effective as of January 1, 2021. The adoption of ASU 2020-06 did not have an impact on the Company’s condensed financial statements as the Company did not hold convertible instruments prior to January 1, 2021.

The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s condensed financial statements.

NOTE 3. INITIAL PUBLIC OFFERING

The Company sold 34,500,000 Units in the Initial Public Offering, which includes a full exercise by the underwriters of their over-allotment option in the amount of 4,500,000 Units at a purchase price of $10.00 per Unit. Each Unit consists of one Class A Ordinary Share and one-fourth of one redeemable Public Warrant. Each whole Public Warrant entitles the holder to purchase one Class A Ordinary Share at an exercise price of $11.50 per Class A Ordinary Share (see Note 8).

NOTE 4. PRIVATE PLACEMENT

Simultaneously with the closing of the Initial Public Offering and the underwriters’ full exercise of their over-allotment option, the Sponsor purchased an aggregate of 9,900,000 Private Placement Warrants at a price of $1.00 per Private Placement Warrant, for an aggregate purchase price of $9,900,000 in a private placement transaction. Each Private Placement Warrant is exercisable to purchase one Class A Ordinary Share at a price of $11.50 per Class A Ordinary Share, subject to adjustment (see Note 8). A portion of the proceeds from the sale of the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares, subject to the requirements of applicable law, and the Private Placement Warrants will expire worthless.

NOTE 5. RELATED PARTY TRANSACTIONS

Founder Shares

On January 28, 2021, the Sponsor transferred 25,000 Founder Shares to certain of the Company’s directors, resulting in the Sponsor holding 8,450,000 Founder Shares. The Founder Shares included an aggregate of up to 1,125,000 Founder Shares that were subject to forfeiture depending on the extent to which the underwriters’ over-allotment option was exercised, so that the number of the Founder Shares would equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. As a result of the underwriters’ election to fully exercise their over-allotment option on February 9, 2021, the 1,125,000 Founder Shares are no longer subject to forfeiture.

The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier of (A) one year after the completion of a Business Combination and (B) subsequent to a Business Combination, (x) if the closing price of the Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property.

Administrative Services Agreement

The Company entered into an agreement, commencing on February 4, 2021, through the earlier of the Company’s consummation of a Business Combination and its liquidation, to pay an affiliate of the Sponsor a sum of $10,000 per month for office space and secretarial and administrative services. For the three and nine months ended September 30, 2021, the Company incurred $30,000 and $80,000, respectively, in fees for these services, of which $10,000 is included in accrued expenses in the accompanying condensed balance sheet as of September 30, 2021.

Promissory Note — Related Party

On December 15, 2020, the Company issued an unsecured promissory note (the “Promissory Note”) to the Sponsor, pursuant to which the Company may borrow up to an aggregate principal amount of $300,000. The Promissory Note was non-interest bearing and payable on the earlier of (i) December 31, 2021 and (ii) the completion of the Initial Public Offering. The outstanding balance under the Promissory Note of $94,890 was repaid at the closing of the Initial Public Offering on February 9, 2021, at which point the Promissory Note was no longer available to the Company.

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s executive officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust

Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of the Working Capital Loans, if any, have not been determined and no written agreements exist with respect to the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,000,000 of the Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of September 30, 2021 and December 31, 2020, there were no amounts outstanding under the Working Capital Loans.

NOTE 6. COMMITMENTS AND CONTINGENCIES 

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that, while it is reasonably possible that the COVID-19 pandemic could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these condensed financial statements. The condensed financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Registration and Shareholder Rights

Pursuant to a registration and shareholder rights agreement entered into on February 4, 2021, the holders of the Founder Shares, the Private Placement Warrants and any warrants that may be issued upon conversion of the Working Capital Loans (and any Class A Ordinary Shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans) will be entitled to registration rights pursuant to a registration and shareholder rights agreement. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination. However, the registration and shareholder rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lockup period. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The underwriters are entitled to a deferred underwriting fee of $0.35 per Unit, or $12,075,000 in the aggregate. The deferred underwriting fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Business Combination Agreement

On July 15, 2021, the Company entered into a definitive business combination agreement (the “Business Combination Agreement”), by and among the Company and Fathom Holdco, LLC to form “Fathom Digital Manufacturing Corporation” (“Fathom”), a publicly-traded industrial technology company that provides digital manufacturing services focused on prototype development and low volume production for blue chip corporate clients.

Pursuant to the transaction, the Company will combine with Fathom at an estimated $1.5 billion pro forma equity value. Cash proceeds in connection with the transaction will be funded through a combination of the Company’s cash in its Trust Account and a $80 million fully committed, common stock private investment in common equity at $10.00 per share.

The transaction will be consummated subject to the deliverables and provisions as further described in the Business Combination Agreement.

NOTE 7. SHAREHOLDERS’ EQUITY

Preference Shares — The Company is authorized to issue 5,000,000 preference shares, with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of September 30, 2021 and December 31, 2020, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue 500,000,000 Class A Ordinary Shares, with a par value of $0.0001 per share. Holders of the Class A Ordinary Shares are entitled to one vote for each Class A Ordinary Share. As of September 30, 2021, there were none issued and outstanding, excluding 34,500,000 Class A Ordinary Shares subject to possible redemption. As of December 31, 2020, there were no Class A Ordinary Shares issued or outstanding.

Class B Ordinary Shares — The Company is authorized to issue 50,000,000 Class B Ordinary Shares, with a par value of $0.0001 per share. Holders of the Class B Ordinary Shares are entitled to one vote for each Class B Ordinary Shares. As of September 30, 2021 and December 31, 2020, there were 8,625,000 Class B ordinary shares issued and outstanding.

Only holders of the Class B Ordinary Shares will have the right to vote on the election of directors prior to the Business Combination. Holders of the Class A Ordinary Shares and the Class B Ordinary Shares will vote together as a single class on all other matters submitted to a vote of shareholders, except as required by law. In connection with a Business Combination, the Company may enter into a shareholders agreement or other arrangements with the shareholders of the target or other investors to provide for voting or other governance arrangements that differ from those in effect upon completion of the Initial Public Offering.

The Class B Ordinary Shares will automatically convert into the Class A Ordinary Shares at the time of a Business Combination, or earlier at the option of the holders thereof, at a ratio such that the number of the Class A Ordinary Shares issuable upon conversion of all of the Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of ordinary shares issued and outstanding upon completion of the Initial Public Offering, plus (ii) the total number of the Class A Ordinary Shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of a Business Combination, excluding the Class A Ordinary Shares or equity-linked securities exercisable for or convertible into the Class A Ordinary Shares issued, deemed issued or to be issued to any seller of an interest in the target to the Company in a Business Combination and any Private Placement Warrants issued to the Sponsor, its affiliates or any member of the Company’s management team upon conversion of the Working Capital Loans. In no event will the Class B Ordinary Shares convert into the Class A Ordinary Shares at a rate of less than one-to-one.

NOTE 8. WARRANT LIABILITY

As of September 30, 2021, there were 8,625,000 Public Warrants outstanding. As of December 31, 2020, there were no Public Warrants outstanding. Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (i) 30 days after the completion of a Business Combination and (ii) one year from the closing of the Initial Public Offering. The Public Warrants will expire five years from the completion of a Business Combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any Class A Ordinary Shares pursuant to the exercise of a Public Warrant and will have no obligation to settle such exercise unless a registration statement under the Securities Act with respect to the Class A Ordinary Shares underlying the Public Warrant is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration, or a valid exemption from registration is available. No Public Warrant will be exercisable and the Company will not be obligated to issue a Class A Ordinary Share upon exercise of a Public Warrant unless the Class A Ordinary Share issuable upon such exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the Public Warrant.

The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of a Business Combination, it will use its commercially reasonable efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A Ordinary Shares issuable upon exercise of the Public Warrants, and the Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days following the closing of a Business Combination, and to maintain the effectiveness of such registration statement and a current prospectus relating to those Class A Ordinary Shares until the Public Warrants expire or are redeemed, as specified in the warrant agreement; provided, however, that, if the Class A Ordinary Shares are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their Public Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Class A Ordinary Shares issuable upon exercise of the Public Warrants, but the Company will use its commercially reasonable efforts to register or qualify for sale the Class A Ordinary Shares under applicable blue sky laws to the extent an exemption is not available. If a registration statement covering the Class A Ordinary Shares issuable upon exercise of the Public Warrants is not effective by the 60th day after the closing of a Business Combination, holders of Public Warrants may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption, but the Company will use its commercially reasonable efforts to register or qualify the Class A Ordinary Shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of the Warrants when the price per Class A Ordinary Share equals or exceeds $18.00. Once the Warrants become exercisable, the Company may redeem the outstanding Warrants (except as described with respect to the Private Placement Warrants):

• in whole and not in part;

• at a price of $0.01 per Warrant;

• upon a minimum of 30 days’ prior written notice of redemption to each holder of the Warrant; and

F-21

ALTIMAR ACQUISITION CORP. II

NOTES TO CONDENSED FINANCIAL STATEMENTS

(Unaudited)

• if, and only if, the closing price of the Class A Ordinary Shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the holders of the Warrants.

If and when the Warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of the Warrants when the price per Class A Ordinary Share equals or exceeds $10.00. Once the Warrants become exercisable, the Company may redeem the outstanding Warrants:

• in whole and not in part;

• at a price of $0.10 per Warrant upon a minimum of 30 days’ prior written notice of redemption; provided, however, that holders will be able to exercise their Warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A Ordinary Shares; and

 

• if, and only if, the closing price of the Class A Ordinary Shares equal or exceeds $10.00 per Class A Ordinary Share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company sends the notice of redemption of the holders of the Warrants.

If the Company calls the Public Warrants for redemption, as described above, the Company’s management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of the Class A Ordinary Shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of the Class A Ordinary Shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of the Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to their Public Warrants. Accordingly, the Public Warrants may expire worthless.

In addition, if (x) the Company issues additional Class A Ordinary Shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per Class A Ordinary Share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or holders of the Class B Ordinary Shares or their respective affiliates, without taking into account any Founder Shares held by the Sponsor, holders of the Class B Ordinary Shares or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the consummation of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of its Class A Ordinary Shares during the 20 trading day period starting on the trading day after the day on which the Company consummates its Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market

Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

As of September 30, 2021, there were 9,900,000 Private Placement Warrants outstanding. As of December 31, 2020, there were no Private Placement Warrants outstanding. The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A Ordinary Shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

NOTE 9. FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial assets and liabilities reflects the Company’s management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

• Level 1 — Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

• Level 2 — Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

• Level 3 — Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

As of September 30, 2021, assets held in the Trust Account were comprised of $345,011,697 in money market funds, which are invested primarily in U.S. Treasury securities.

The following table presents information about the Company’s assets and liabilities that are measured at fair value on a recurring basis as of September 30, 2021 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

Description	Level		September 30, 2021
Assets:
Investments held in the Trust Account		1		345,011,697
Liabilities:
Warrant liability — Public Warrants		1	$	9,070,433

The Warrants were accounted for as liabilities in accordance with ASC 815-40 and are presented within warrant liability in the accompanying condensed balance sheet. The warrant liabilities are measured at fair value at inception and on a recurring basis, with changes in fair value presented within change in fair value of warrant liabilities in the condensed statement of operations. The Warrants were initially valued using a Monte Carlo simulation model, which is considered to be a Level 3 fair value measurement for which there are uncertainties involved. If factors or assumptions change, the estimated fair values could be materially different. The Monte Carlo simulation model’s primary unobservable input utilized in determining the fair value of the Warrants is the expected volatility of the ordinary shares. The expected volatility as of the closing date of the Initial Public Offering was derived from observable public warrant pricing on comparable ‘blank-check’ companies without an identified target. The expected volatility as of subsequent valuation dates was implied from the Company’s own public warrant pricing. A Monte Carlo simulation methodology was used in estimating the fair value of the Public Warrants for periods where no observable traded price was available, using the same expected volatility as was used in measuring the fair value of the Private Warrants. The Public Warrants have detached from the Units and the Public Warrants were moved from Level 3 to Level 1. For periods subsequent to the detachment, the closing price of the Public Warrants will be used as the fair value as of each relevant date.

The following table provides quantitative information regarding Level 3 fair value measurements:

	As of September 30, 2021

To the Shareholders and the Board of Directors of

Altimar Acquisition Corp. II

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Altimar Acquisition Corp. II (the “Company”) as of December 31, 2020, the related statements of operations, changes in shareholder’s equity and cash flows for the period from December 7, 2020 (inception) through December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020, and the results of its operations and its cash flows for the period from December 7, 2020 (inception) through December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

NOTES TO FINANCIAL STATEMENTS

Note 1 — Organization and Plan of Business Operations

Altimar Acquisition Corp. II (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on December 7, 2020. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”).

The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of December 31, 2020, the Company had not commenced any operations. All activity for the period from December 7, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the proposed initial public offering (“Proposed Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Proposed Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a Proposed Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”) at $10.00 per Unit (or 34,500,000 Units if the underwriters’ over-allotment option is exercised in full), which is discussed in Note 3, and the sale of 9,000,000 warrants (or 9,900,000 warrants if the underwriters’ over-allotment option is exercised in full) (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant in a private placement to Altimar Sponsor II, LLC (the “Sponsor”), that will close simultaneously with the Proposed Public Offering.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The stock exchange listing rules require that the Business Combination must be with one or more operating businesses or assets with a fair market value equal to at least 80% of the assets held in the Trust Account (as defined below) (excluding the amount of deferred underwriting commissions and taxes payable on the income earned on the Trust Account). The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Public Offering, management has agreed that $10.00 per Unit sold in the Proposed Public Offering, including proceeds of the sale of the Private Placement Warrants, will be held in a trust account (the “Trust Account”) and invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or in any open-ended investment company that holds itself out as a money market fund investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below.

The Company will provide the holders of the public shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their public shares either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek

F-30

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two business days prior to the consummation of the Business Combination (initially anticipated to be $10.00 per Public Share), including interest (which interest shall be net of taxes payable), divided by the number of then issued and outstanding public shares, subject to certain limitations as described in the prospectus. The per-share amount to be distributed to the Public Shareholders who properly redeem their shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 6). There will be no redemption rights in connection with a Business Combination with respect to the Company’s warrants. The Class A ordinary shares will be recorded at redemption value and classified as temporary equity upon the completion of the Proposed Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.”

The Company will not redeem Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001 (so that it does not then become subject to the SEC’s “penny stock” rules) or any greater net tangible asset or cash requirement that may be contained in the agreement relating to the Business Combination. If the Company seeks shareholder approval of the Business Combination, the Company will proceed with a Business Combination only if the Company receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who attend and vote at a general meeting of the Company, or such other vote as required by law or stock exchange rule. If a shareholder vote is not required and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (the “SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased during or after the Proposed Public Offering in favor of approving a Business Combination. Additionally, each Public Shareholder may elect to redeem their Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the Trust account and not previously released to pay taxes, divided by the number of then issued and outstanding Public Shares.

F-31

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

The Company will have until 24 months from the closing of the Proposed Public Offering to consummate a Business Combination (the “Combination Period”). However, if the Company has not completed a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned and not previously released to us to pay our taxes, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding Public Shares, which redemption will completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidating distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Public Shareholders and its Board of Directors, liquidate and dissolve, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Company’s warrants, which will expire worthless if the Company fails to complete a Business Combination within the Combination Period.

The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares it will receive if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period, and in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Proposed Public Offering price per Unit ($10.00).

In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below the lesser of (1) $10.00 per Public Share and (2) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share, due to reductions in the value of trust assets, in each case net of the interest that may be withdrawn to pay taxes. This liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriters of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). In the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Note 2 — Significant Accounting Policies

Basis of Presentation

The accompanying financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the rules and regulations of the SEC.

F-32

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

The Company does not have sufficient liquidity to meet its anticipated obligations over the next year from the date of issuance of these financial statements. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” management has determined that the Company has access to funds from the Sponsor that are sufficient to fund the working capital needs of the Company until the earlier of the consummation of the Proposed Public Offering and one year from the date of issuance of these financial statements.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Deferred Offering Costs

Deferred offering costs consist of legal, accounting and other expenses incurred through the balance sheet date that are directly related to the Proposed Public Offering and that will be charged to shareholder’s equity upon the completion of the Proposed Public Offering. Should the Proposed Public Offering prove to be unsuccessful, these deferred costs, as well as additional expenses incurred, will be charged to operations.

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

Income Taxes

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2020, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented.

Net Loss Per Ordinary Share

Net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares issued and outstanding during the period, excluding ordinary shares subject to forfeiture. Weighted average shares were reduced for the effect of an aggregate of 1,125,000 Class B ordinary shares that are subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised (see Note 5). At December 31, 2020, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted loss per ordinary share is the same as basic loss per ordinary share for the period presented.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times may exceed the Federal Depository Insurance Coverage of $250,000. The Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on such accounts.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheet, primarily due to their short-term nature.

Recent Accounting Standards

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company’s financial statements.

Pursuant to the Proposed Public Offering, the Company will offer for sale up to 30,000,000 Units (or 34,500,000 Units if the underwriters’ over-allotment option is exercised in full) at a purchase price of $10.00 per Unit. Each Unit will consist of one Class A ordinary share and one-fourth of one redeemable warrant (“Public Warrant”). Each whole Public Warrant will entitle the holder to purchase one Class A ordinary share at an exercise price of $11.50 per whole share (see Note 7).

Note 4 — Private Placement

The Sponsor has committed to purchase an aggregate of 9,000,000 Private Placement Warrants (or 9,900,000 Private Placement Warrants if the underwriters’ over-allotment option is exercised in full) at a price of $1.00 per Private Placement Warrant, for an aggregate purchase price of $9,000,000 (or $9,900,000 if the underwriters’ over-allotment option is exercised in full), in a private placement that will occur simultaneously with the closing of the Proposed Public Offering. Each Private Placement Warrant is exercisable to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment (see Note 7). A portion of the proceeds from the Private Placement Warrants will be added to the proceeds from the Proposed Public Offering to be held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless.

Note 5 — Related Party Transactions

Founder Shares

On December 15, 2020, the Sponsor paid $25,000 to cover certain offering and formation costs of the Company in consideration for 8,625,000 Class B ordinary shares (the “Founder Shares”). The Founder Shares include an aggregate of up to 1,125,000 shares that are subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised, so that the number of Founder Shares will equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Proposed Public Offering.

The Sponsor has agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier of (A) one year after the completion of a Business Combination and (B) subsequent to a Business Combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

Administrative Services Agreement

The Company will enter into an agreement, commencing on the date that the securities are first listed on the NYSE through the earlier of the Company’s consummation of a Business Combination and its liquidation, to pay an affiliate of the Sponsor a sum of $10,000 per month for office space and secretarial and administrative services.

Promissory Note — Related Party

On December 15, 2020, the Company issued an unsecured promissory note (the “Promissory Note”) to the Sponsor, pursuant to which the Company may borrow up to an aggregate principal amount of $300,000. The Promissory Note is non-interest bearing and payable on the earlier of (i) December 31, 2021 and (ii) the completion of the Proposed Public Offering. As of December 31, 2020, there was $5,000 in borrowings outstanding under the Promissory Note.

NOTES TO FINANCIAL STATEMENTS

Related Party Loans

In order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,000,000 of such Working Capital Loans may be convertible into warrants of the post-Business Combination entity at a price of $1.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of December 31, 2020, the Company had no outstanding borrowings under the Working Capital Loans.

Note 6 — Commitments and Contingencies

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 global pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations, close of the Proposed Public Offering and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Registration and Shareholders Rights

The holders of the Founder Shares, Private Placement Warrants and any warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans) will be entitled to registration rights pursuant to a registration and shareholder rights agreement to be signed prior to or on the effective date of the Proposed Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of a Business Combination. However, the registration and shareholder rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lockup period. The registration rights agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company will grant the underwriters a 45-day option to purchase up to 4,500,000 additional Units to cover over-allotments at the Proposed Public Offering price, less the underwriting discounts and commissions.

The underwriters will be entitled to a cash underwriting discount of $0.20 per Unit, or $6,000,000 in the aggregate (or $6,900,000 if the underwriters’ over-allotment option is exercised in full), payable upon the closing of the Proposed Public Offering. In addition, the underwriters will be entitled to a deferred fee of $0.35 per Unit,

F-36

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

or $10,500,000 in the aggregate (or $12,075,000 in the aggregate if the underwriters’ over-allotment option is exercised in full). The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.​​​​​​​

Note 7 — Shareholder’s Equity

Preference Shares — The Company is authorized to issue 5,000,000 preference shares with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. At December 31, 2020, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue 500,000,000 Class A ordinary shares, with a par value of $0.0001 per share. Holders of Class A ordinary shares are entitled to one vote for each share. At December 31, 2020, there were no Class A ordinary shares issued or outstanding.

Class B Ordinary Shares — The Company is authorized to issue 50,000,000 Class B ordinary shares, with a par value of $0.0001 per share. Holders of the Class B ordinary shares are entitled to one vote for each share. At December 31, 2020, there were 8,625,000 Class B ordinary shares issued and outstanding, of which an aggregate of up to 1,125,000 shares are subject to forfeiture depending on the extent to which the underwriters’ over-allotment option is exercised, so that the number of Class B ordinary shares will equal 20% of the Company’s issued and outstanding ordinary shares after the Proposed Public Offering.

Only holders of the Class B ordinary shares will have the right to vote on the election of directors prior to the Business Combination. Holders of Class A ordinary shares and Class B ordinary shares will vote together as a single class on all other matters submitted to a vote of shareholders, except as required by law. In connection with a Business Combination, the Company may enter into a shareholders agreement or other arrangements with the shareholders of the target or other investors to provide for voting or other governance arrangements that differ from those in effect upon completion of the Proposed Public Offering.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of a Business Combination or earlier at the option of the holders thereof at a ratio such that the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the sum of (i) the total number of ordinary shares issued and outstanding upon completion of the Proposed Public Offering, plus (ii) the total number of Class A ordinary shares issued or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of a Business Combination, excluding Class A ordinary shares or equity-linked securities exercisable for or convertible into Class A ordinary shares issued, deemed issued, or to be issued, to any seller of an interest in the target to the Company in a Business Combination and any Private Placement Warrants issued to the Sponsor, its affiliates or any member of the Company’s management team upon conversion of Working Capital Loans. In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than one-to-one.

Warrants — Public Warrants may only be exercised for a whole number of shares. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination and (b) one year from the closing of the Proposed Public Offering. The Public Warrants will expire five years from the completion of a Business Combination or earlier upon redemption or liquidation.

F-37

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

The Company will not be obligated to deliver any Class A ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the Class A ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration, or a valid exemption from registration is available. No warrant will be exercisable and the Company will not be obligated to issue a Class A ordinary share upon exercise of a warrant unless the Class A ordinary share issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants.

The Company has agreed that as soon as practicable, but in no event later than 20 business days, after the closing of a Business Combination, it will use its commercially reasonable efforts to file with the SEC a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, and the Company will use its commercially reasonable efforts to cause the same to become effective within 60 business days following the closing of a Business Combination, and to maintain the effectiveness of such registration statement and a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement; provided that if the Class A ordinary shares are at the time of any exercise of a public warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Class A ordinary shares issuable upon exercise of the warrants, but the Company will use its commercially reasonable efforts to register or qualify for sale the shares under applicable blue sky laws to the extent an exemption is not available. If a registration statement covering the Class A ordinary shares issuable upon exercise of the warrants is not effective by the 60th day after the closing of a Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption, but the Company will use its commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $18.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described with respect to the Private Placement Warrants):

• in whole and not in part;

• at a price of $0.01 per warrant;

• upon a minimum of 30 days’ prior written notice of redemption to each warrant holder; and

• if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders.

If and when the warrants become redeemable by the Company, the Company may exercise its redemption right even if it is unable to register or qualify the underlying securities for sale under all applicable state securities laws.

Redemption of warrants when the price per Class A ordinary share equals or exceeds $10.00. Once the warrants become exercisable, the Company may redeem the outstanding warrants:

• in whole and not in part;

F-38

ALTIMAR ACQUISITION CORP. II

NOTES TO FINANCIAL STATEMENTS

• at $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption; provided that holders will be able to exercise their warrants on a cashless basis prior to redemption and receive that number of shares determined based on the redemption date and the fair market value of the Class A ordinary shares;

• if, and only if, the closing price of the Class A ordinary shares equal or exceeds $10.00 per public share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company send the notice of redemption of the warrant holders.

If the Company calls the Public Warrants for redemption, as described above, its management will have the option to require any holder that wishes to exercise the Public Warrants to do so on a “cashless basis,” as described in the warrant agreement. The exercise price and number of ordinary shares issuable upon exercise of the Public Warrants may be adjusted in certain circumstances including in the event of a share dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation. However, except as described below, the Public Warrants will not be adjusted for issuances of ordinary shares at a price below its exercise price. Additionally, in no event will the Company be required to net cash settle the Public Warrants. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of Public Warrants will not receive any of such funds with respect to their Public Warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with respect to such Public Warrants. Accordingly, the Public Warrants may expire worthless.

In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per Class A ordinary share (with such issue price or effective issue price to be determined in good faith by the Company’s board of directors and, in the case of any such issuance to the Sponsor or holders of the Class B ordinary shares or their respective affiliates, without taking into account any Founder Shares held by the Sponsor, holders of the Class B ordinary shares or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of a Business Combination on the date of the consummation of a Business Combination (net of redemptions), and (z) the volume weighted average trading price of its Class A ordinary shares during the 20 trading day period starting on the trading day after the day on which the Company consummates its Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price, and the $10.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants will be identical to the Public Warrants underlying the Units being sold in the Proposed Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon the exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except as described above, so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Note 1 — Nature of Business

Fathom Holdco, LLC (the “Company”) was formed on April 16, 2021 as a limited liability company in accordance with the provisions of the Delaware Limited Liability Company Act, as amended (the “Delaware Act”), for the purpose of holding a 100 percent equity interest in MCT Group Holdings, LLC and its subsidiaries (“MCT Holdings”) and holding a 100 percent equity interest in Incodema Holdings, LLC and its subsidiaries (“Incodema Holdings”). For purposes of this report, “Fathom Holdco,” the “Company,” “we,” “our,” “us,” or similar references mean Fathom Holdco, LLC and our consolidated subsidiaries unless the context requires otherwise.

On April 30, 2021, the Company completed a common control reorganization (the “Reorganization”) whereby the interests in both MCT Holdings and Incodema Holdings were contributed to the Company. Prior to and subsequent to the Reorganization, MCT Holdings, Incodema Holdings, and the Company were each, directly or indirectly, under the common control of CORE Industrial Partners Fund I, L.P. (“CORE”) As such, after the completion of the Reorganization, the historical financial statements of the Company were retrospectively updated in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) guidance for common control transactions.

The Company and its subsidiaries offer prototyping and low-volume services across a variety of in-house additive manufacturing technologies, as well as precision sheet metal and finishing services ranging from prototype through mid-volume production including internal sheet metal cutting and forming solutions, as well as chemical etching for customers in the aerospace and defense, electronics, medical, automotive, and various other industries. In addition to three-dimensional (“3D”) printing and processing, the Company also offers computer numerical control (“CNC”) machining, injection molding and industrial design capabilities to a diversified customer base in various industries and geographical locations.

Going Concern

In accordance with U.S. GAAP, the Company is required to evaluate whether there are conditions or events that exist as of the date of issuance of these Unaudited Condensed Consolidated Financial Statements that raise doubt as to the Company’s ability to continue as a going concern within the twelve months following issuance.

On April 30, 2021, the Company completed a financing transaction whereby it issued a $172,000 term loan due April 2022 (the “2021 Term Loan”) in order to finance the acquisitions of Centex Machine and Welding, Inc. (“Centex”), Laser Manufacturing, Inc. (“Laser”), Sureshot Precision, LLC d/b/a Micropulse West (“Micropulse West”), and Precision Process Corporation (“PPC”), as well as to refinance the Company’s existing debt, as described in Note 8.

As the Company does not have sufficient cash on hand and cash flow from operations to repay the 2021 Term Loan, the maturity of the 2021 Term Loan raises substantial doubt about our ability to continue as a going concern within the next twelve months. If we are unable to repay, refinance or restructure our 2021 Term Loan, our assets may not be sufficient to repay in full the amounts owed.

To address the upcoming maturity of the 2021 Term Loan, the Company has entered into a new credit facility with its existing creditors (the “New Credit Agreement”). The New Credit Agreement includes a $50,000 revolving credit facility and $125,000 term loan and matures in 2026. The proceeds from these loans will be used to repay the April 2021 Term Loan.

The funding of the New Credit Agreement is contingent on the Company closing a definitive business combination with a publicly traded Special Purpose Acquisition Company (“SPAC”) before April 9, 2022 (the

F-45

“SPAC Transaction”). In addition, the cash proceeds of such SPAC Transaction must be in excess of $313,000, or a lesser amount if mutually agreed by the Company and the SPAC.

The Company intends to use the proceeds from the New Credit Agreement to repay the April 2021 Term Loan. If the SPAC Transaction is not completed prior to April 9, 2022, the Company will not receive any funds nor incur any indebtedness from the New Credit Agreement. Given the SPAC Transaction will be subject to regulatory and market conditions, approval by a SPAC’s shareholders, and the SPAC securing adequate financing, it is not within the Company’s control and therefore cannot be deemed probable as of the issuance of these unaudited condensed consolidated financial statements. As a result, the Company has concluded that management’s plans described above do not alleviate substantial doubt about the Company’s ability to continue as a going concern for the next twelve months.

The accompanying unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Announcement of the SPAC Transaction

On July 16, 2021, the Company and Altimar Acquisition Corp. II (NYSE:ATMR)(“Altimar”), a special purpose acquisition company, announced that they have entered into a definitive business combination agreement (the “Business Combination Agreement”) pursuant to which the Company and Altimar will combine, and after which the combined company will become a publicly-traded company. Upon completion of the transaction, the combined company expects to be listed on the New York Stock Exchange.

As discussed further in Note 15, on November 16, 2021, Altimar and the Company executed amendment No. 1 to the Business Combination Agreement (the “Amendment No. 1 to the Business Combination Agreement”) that amended certain terms of the business combination agreement executed on July 16, 2021. Amendment No.1 to the Business Combination Agreement does not alter the fact that, upon closing of the transaction, the combined company, to be name Fathom Digital Manufacturing Company, will become a publicly traded company that is listed on the New York Stock Exchange.

New Credit Agreement

On July 9, 2021, the Company entered into a financing transaction, which included a $50,000 revolving credit facility and $125,000 term loan, which will be funded at a later date assuming certain subsequent conditions are met including the closing of the SPAC Transaction noted above. See Going concern section of Note 1 and Note 15 for additional information.

Note 2 — Significant Accounting Policies

Basis of Presentation

These Unaudited Condensed Consolidated Financial Statements of the Company are comprised of the Company’s subsidiaries from the date on which they were acquired. Each subsidiary is wholly owned by either MCT Holdings or Incodema Holdings, both of which are wholly owned by the Company.

The Unaudited Condensed Consolidated Financial Statements have been prepared in conformity with U.S. GAAP pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, they do not include all of the information and notes required by U.S. GAAP for complete financial statements. In the opinion of the Company, these Unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of only recurring adjustments, necessary for a fair representation of the Company’s financial position as of September 30, 2021, its results of operations for the nine

F-46

months ended September 30, 2021 and September 30, 2020, and its cash flows for the nine months ended September 30, 2021 and September 30, 2020.

The Unaudited Condensed Consolidated Balance Sheet as of December 31, 2020, included herein for comparative purposes, was derived from the Company’s audited consolidated balance sheet for the year ended December 31, 2020.

These Unaudited Condensed Consolidated Financial Statements do not contain certain footnote disclosures that were included as part of the Company’s audited annual financial statements. As such, these Unaudited Condensed Consolidated Financial Statements should be read in conjunction with the Company’s audited annual financial statements for the years ended December 31, 2020 and 2019, which describes the Company’s significant accounting policies and includes all disclosures required by U.S. GAAP for annual reporting periods.

Income Taxes

The Company wholly owns Summit Tooling, Inc. (“Summit Tooling”), Centex, and Laser, which are treated as taxpaying C corporations in the U.S. Each of the Company’s taxpaying subsidiaries were acquired in 2021. Accordingly, the Company provides current and deferred taxes for these entities. The Company and its other subsidiaries are treated as flow-through entities for federal and state income tax purposes and are not subject to income tax as the LLC members are responsible for the tax consequences of each member’s proportionate share of the flow-through income or loss of the remaining Company operations. The Company’s flow-through operations are subject to certain state and local income and franchise taxes, which are included in the Consolidated Statements of Comprehensive Loss as other income, net. In addition, MCT Holdings’ wholly owned subsidiary, ICO Mold (Shenzhen), LLC, is subject to income tax within the jurisdiction of the People’s Republic of China. Foreign income tax expense was insignificant during both the nine months ended September 30, 2021 and September 30, 2020. As such, the Company’s tax provision pertains solely to the taxpaying C corporation subsidiaries.

The Company’s taxable subsidiaries account for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the future tax consequences of temporary differences between the book carrying values and the tax basis of the assets, liabilities, and tax attributes (e.g., NOLs) of the taxable subsidiaries. The Company is in a net deferred tax liability position which is classified as noncurrent on the Unaudited Condensed Consolidated Balance Sheet. The Company establishes a valuation allowance when necessary to reduce deferred tax assets to the amount that are more likely than not to be realized. The Company has evaluated the need for a valuation allowance and has determined that deferred tax assets are more likely than not to be realized.

The Company evaluates tax positions taken or expected to be taken in a tax return for financial statement recognition. A tax position is recognized when it is more likely than not that the tax position will be sustained upon examination, including the resolution of appeals or litigation. The Company records the amount of benefits from tax positions taken that have a greater than 50% likelihood of being realized upon settlement with taxing authorities. Interest and penalties related to unrecognized tax benefits are recognized in the income tax benefits in the accompanying Unaudited Condensed Consolidated Statements of Comprehensive Loss. No interest and penalties were recognized for the periods presented.

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus as a “pandemic”. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of these Unaudited Condensed Consolidated Financial Statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the Consolidated Balance Sheet dates, as no triggering events or changes in circumstances had occurred as of year-end or as of the most

F-47

recent quarter-end; however, due to uncertainty surrounding the situation, and specifically as it pertains to the current global supply chain disruptions, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

Recent Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, which will supersede the current lease requirements in ASC 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The new lease guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a modified retrospective transition method to either the beginning of the earliest period presented or the beginning of the year of adoption. The new lease standard is expected to have a significant effect on the Company’s financial statements as a result of the Company’s operating leases, that will be reported on the balance sheet at adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

The FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments including trade receivables and available for sale debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company continues to evaluate the impact of this ASU on its Consolidated Financial Statements.

Note 3 — Business Combinations

The transactions below met the requirements to be considered a business combination under Accounting Standards Codification (“ASC”) 805. The accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s financial statements from the date of acquisition. The Company has allocated the purchase price to the tangible assets, identifiable intangible assets and liabilities based on their estimated fair market values at the acquisition date as required under ASC 805. The excess of the purchase price over the fair value of the net identifiable tangible assets, intangible assets and liabilities was recorded as goodwill.

The pro forma consolidated results do not purport to project future results of combined operations, nor do they reflect the expected realization of any revenue or cost synergies.

Note 4 — Revenue

The Company accounts for revenue in accordance with ASC 606, Revenue from Contracts with Customers, which the Company adopted on January 1, 2019, using the modified retrospective method. The adoption of ASC 606 did not have a material impact on our Unaudited Condensed Consolidated Financial Statements.

2018 and 2019 Credit Facilities

During 2018, the Company entered a revolving credit agreement, a term loan and a delayed draw term loan (“DDTL”) credit agreement, which collectively make up the “2018 Credit Facilities”, to support its operations, cash requirements and acquisition growth strategy. During 2019, the Company entered into the second and third amendments to the 2018 Credit Facilities. Under the credit agreement, the Company is subject to various financial covenants, including quarterly fixed-charge coverage ratio; total leverage ratio; and minimum earnings before interest, taxes, depreciation, and amortization (“EBITDA”). The credit facility also includes a capital expenditure limit of $3,100 for the year ended December 31, 2020. As of December 31, 2020, the Company was in compliance with all covenant requirements. The 2018 DDTL had unused capacity of $510 December 31, 2020 and was fully repaid as of September 30, 2021.

2020 Credit Facilities

On July 27, 2020, the Company entered into a $34,500 secured, unsubordinated credit facility with a financial institution, consisting of a $19,500 term loan and a $15,000 delayed draw term loan, with a maturity of July 27, 2026. At closing, $19,500 was funded and along with cash on the Company’s balance sheet, used to finance the acquisition of Incodema and Newchem. The term loan credit facility resulted in issuance costs of $520, which were capitalized. The loan is secured by pledged equity interests and the assets of the Company, including, but not limited to, cash and deposits, inventory, property, plant, and equipment, and intangible assets. Under the agreements, the Company is subject to various financial covenants, including a fixed charge coverage ratio and total net leverage ratio, and required to make quarterly principal installments commencing on

F-56

September 30, 2020 and March 31, 2021 through the end of the term in the amounts of $50 and $100 for the term loan and delayed draw term loan, respectively. Commencing with the year ending December 31, 2021, mandatory prepayments are required from the Company’s Excess Cash Flow, as defined by the Credit Agreement. Borrowing under the Term Loan Facility is in U.S. Dollars and bears interest at a variable interest rate based on LIBOR plus a net leverage-based margin, which was 7.738% per annum as of December 31, 2020.

On December 16, 2020, the Company entered into the first amendment to the 2020 Credit Facility. Pursuant to the amendment, the availability on the delayed draw term loan was increased to $40,500. The Company is charged a Commitment Fee of 0.5% for the initial six month period and 1.0% following the six month period on the unused portion of the delayed draw term loan. The amendment resulted in issuance costs of $692 of which $660 were capitalized and $32 were expensed. Borrowings on the delayed draw term loan amount were not drawn until acquisitions of Dahlquist, Mark Two, and Majestic Metals beginning mid-December. The 2020 DDTL was fully drawn as of December 31, 2020 and was repaid as of September 30, 2021.

2021 Term Loan

On April 30, 2021, the Company completed a financing transaction whereby it issued a $172,000 term loan due April 2022 (the “2021 Term Loan”) in order to finance the acquisitions of Centex, Laser, Micropulse West, and PPC, as well as to refinance the Company’s existing debt. The 2021 Term Loan is due for repayment on April 29, 2022. As discussed further in Notes 1 and 15, on July 9, 2021 the Company entered into an agreement to refinance the 2021 Term Loan on a permanent basis, subject to certain conditions. As of September 30, 2021, the Company was in compliance with all 2021 Term Loan covenants. See Notes 1 and 15 for further information.

Paycheck Protection Program Loan

During the year ended December 31, 2020, the Company received a Paycheck Protection Program (“PPP”) loan in the amount of $1,624 through the Small Business Administration (“SBA”) under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act.

In April 2021, the Company’s PPP loan was forgiven in full by the SBA and the Company recorded a gain of $1,624 which was recorded to other income on the Company’s Unaudited Condensed Consolidated Statement of Comprehensive Loss for the nine months ended September 30, 2021.

Included in interest expense, net on the accompanying Unaudited Condensed Consolidated Statements of Comprehensive Loss is amortization of debt issuance costs of $1,342 and $153 that were expensed for the nine months ended September 30, 2021 and September 30, 2020, respectively.

New Credit Agreement

On July 9, 2021, the Company entered into a financing transaction, which included a $50,000 revolving credit facility and $125,000 term loan, which will be funded at a later date assuming certain subsequent conditions are met including the closing of the SPAC Transaction noted above. The loans made under the New Credit Agreement will mature in 2026. Funding of loans under the New Credit Agreement is conditioned upon completing the SPAC Transaction noted above before April 9, 2022. In addition, funding of the loans under the New Credit Agreement is further conditioned on the cash proceeds of the SPAC Transaction being in excess of $313 million, or a lesser amount if mutually agreed. The Company expects that the proceeds from the SPAC Transaction will be less than $313,000, however the Company and Altimar have mutually agreed that the New Credit Agreement will be funded despite the cash proceeds being less than $313,000.

F-58

The revolving credit facility under the New Credit Agreement will be available for working capital and other general corporate purposes and will include a letter of credit sub-facility of up to $5 million. The New Credit Agreement will also include an uncommitted incremental facility, which, subject to certain conditions, will provide for additional term loan facilities, an increase in commitments under the New Credit Agreement and/or an increase in commitments under the revolving credit facility, in an aggregate amount of up to $100,000. See Going concern section of Note 1 for additional information.

Note 10 — Earnings Per Unit

Basic and diluted earnings per common unit is presented in conformity with the two-class method required for participating securities. The holders of the Company’s Class A Preferred Units are entitled to accrue cumulative dividends at the rate of 8% per annum. The Company considered its contingently redeemable preferred units to be participating securities and, in accordance with the two-class method, earnings allocated to preferred units have been excluded from the computation of basic and diluted net income or loss per common unit.

Basic net loss per unit is computed based on the weighted average number of common units outstanding. Diluted net loss per unit is computed based on the weighted average number of common units outstanding, increased by the number of any additional units that would have been outstanding had any potentially dilutive common units been issued and reduced by the number of units the Company could have repurchased from the proceeds from issuance of the potentially dilutive units. The Company had no dilutive instruments outstanding as of September 30, 2021 and September 30, 2020. As a result, basic and diluted earnings per units are the same as of September 30, 2021 and September 30, 2020.

The Company’s Class A and Class B common units participate equally in the Company’s undistributed earnings. As such, the Company’s undistributed earnings are allocated pro-rata to the Class A and Class B common units based on the weighted Class A common and Class B common units outstanding as of September 30, 2021 and September 30, 2020 such that earnings per unit for Class A and Class B common units are the same in each period.

For the nine months ended September 30, 2021 and September 30, 2020, the Company incurred expenses related to such management fees of $1,431 and $355, respectively.

See Note 3 for additional disclosure of transaction fees paid to the same entity related through common ownership to the majority member.

Note 12 — Fair Value Measurement

Accounting standards require certain assets and liabilities be reported at fair value in the financial statements and provide a framework for establishing that fair value. The framework for determining fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. There are three levels of inputs that may be used to measure fair value:

Fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques considering the characteristics of the asset.

F-60

In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

The Company used the following methods and significant assumptions to estimate fair value:

Contingent Consideration: The fair values for earnouts payable are determined by using a discounted cash flow (“DCF”) approach with unobservable inputs and is classified as a Level 3 liability in the fair value hierarchy. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

Assets and liabilities measured at fair value on a recurring basis, are summarized below:

	Fair Value Measurement at September 30, 2021 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Contingent consideration	$	—	$	—	$	8,630	$	8,630

	Fair Value Measurement at December 31, 2020 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Contingent consideration	$	—	$	—	$	11,439	$	11,439

The table below presents a reconciliation of all liabilities measured at fair value on a recurring basis using significant on observable inputs (Level 3) as of and for the nine months ended September 30, 2021 and as of and for the twelve months ended December 31, 2020:

	Contingent Consideration
	September 30, 2021			December 31, 2020
Balance of recurring Level 3 liabilities at January 1	$	11,439		$	—
Total gains or losses for the period:

Transfers into Level 3		—			—
Transfers out of Level 3		—			—
Balance of recurring Level 3 liabilities at end of period	$	8,630		$	11,439

The valuation techniques used to determine the fair value of the contingent consideration as of September 30, 2021 and December 31, 2020 included a combination of discounted cash flow, Black Scholes-Merton model, and Monte Carlo simulation. The significant unobservable inputs used in the calculation of fair value include the discount rate, volatility, and credit spreads. The discount rates range from 2.9% to 18.8%, the volatility ranges from 15.3% to 80.2%, and the credit spreads range from 5.2% to 6.6%.

Debt: As of September 30, 2021, the fair value of the 2021 Term Loan approximates its carrying value.

Note 13 — Commitments and Contingencies

The Company is subject to various claims and lawsuits that arise in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material effect on the consolidated financial position of the Company.

In July 2021, the Company entered into a settlement agreement in a hybrid collective/class action complaint filed by one of its former employees for alleged violations of the Fair Labor Standards Act and Wisconsin wage and hour law. The settlement amount did not have a material effect on the consolidated financial position of the Company.

Note 14 — Income Taxes

The Company and most of its subsidiaries are treated as flow-through entities for federal and state income tax purposes and are not subject to income tax as the LLC members are responsible for the tax consequences of each member’s proportionate share of the flow-through income or loss. As such, the Company’s tax provision pertains solely to its subsidiaries which are taxable C corporations for U.S. federal income tax purposes.

The Company’s effective income tax rate was (11.1%) and 0.0% for the nine months ended September 30, 2021 and September 30, 2020, respectively. The change in the Company’s effective income tax rate for the nine months ended September 30, 2020 and compared to the nine months ended September 30, 2021 relates to the acquisitions of three taxable C corporations during 2021. The effective tax rate for the nine months ended September 30, 2021 differs from the statutory tax rate of 21% primarily as a result of operations held in flow-through entities, state taxes, and the impact of certain transaction costs which were capitalized for tax purposes, but are not expected to result in deduction is future tax periods.

As of September 30, 2021, the Company did not recognize income tax expense or benefits associated with uncertain tax positions.

Significant components of the Company’s tax expense for the nine months ended September 30, 2021 and September 30, 2020, are as follows (in thousands):

• The minimum cash condition required to close the transaction was reduced from $313,000 to $90,000

• The amount of cash to be contributed to the Company’s balance sheet upon closing of the transactions was reduced from $25,000 to $10,000

• The minimum amount of Company debt to be paid down upon closing of the transaction was reduced from $22,000 to $20,000

• Provisions relating to the forfeiture of certain shares in the surviving company by Altimar’s founders based on the level of redemptions were amended and restated to provide for a forfeiture of by such founders of 2,587,500 shares

• The equity consideration payable to the owners of the Company was increased by 1,293,750 shares

• Provisions were added to reflect the backstop commitment by affiliates of the majority member of the Company to purchase up to 1,000 shares of Altimar at an aggregate price of up to $10,000 to the extent necessary to satisfy the revised minimum cash condition

As a result of Amendment No. 1 to Business Combination Agreement, the Company continues to expect to combine with Altimar and the combined company, to be named Fathom Digital Manufacturing Corporation, will be publicly traded and listed on the New York Stock Exchange.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Managers and Members

Fathom Holdco, LLC

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Fathom Holdco, LLC (a Delaware limited liability company) and subsidiaries (the “Company”) as of December 31, 2020 and 2019, the related consolidated statements of comprehensive loss, Class A contingently redeemable preferred units and members’ equity, and cash flows for each of the two years in the period ended December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Going concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, as of December 31, 2020, the Company does not have sufficient cash on hand and cash flows from operations to repay debt maturing during April 2022. On July 9, 2021 the Company entered into a new credit facility with its existing creditors. The new credit facility includes a $50,000,000 revolver and $125,000,000 term loan, both of which will mature in 2026. The proceeds from these loans will be used to repay existing debt maturing April 2022. Funding under the new credit facility is contingent on the Company closing a definitive business combination with a publicly traded Special Purpose Acquisition Company (“SPAC”), which is subject to customary conditions including, among others, the approval of the SPAC stockholders and the SPAC having a minimum level of available cash, which are outside of the Company’s control. There is no guarantee that the business combination contemplated in the new credit facility will be completed and therefore the Company has concluded that substantial doubt exists about the Company’s ability to continue as a going concern.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

F-64

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ GRANT THORNTON LLP

We have served as the Company’s auditor since 2021.

Fathom Holdco, LLC

Notes to Consolidated Financial Statements

(dollars in thousands, unless otherwise noted)

Note 1 — Nature of Business

Fathom Holdco, LLC (the “Company”) was formed on April 16, 2021 as a limited liability company in accordance with the provisions of the Delaware Limited Liability Company Act, as amended (the “Delaware Act”), for the purpose of holding a 100 percent equity interest in MCT Group Holdings, LLC and its subsidiaries (“MCT Holdings”) and holding a 100 percent equity interest in Incodema Holdings, LLC and its subsidiaries (“Incodema Holdings”). As of December 31, 2020, both MCT Holdings and Incodema Holdings were under the common control of CORE Industrial Partners Fund I, L.P. (“CORE”).

MCT Holdings was formed on August 27, 2018 as a limited liability company in accordance with the Delaware Act for the purpose of holding 100 percent of the equity interest in Midwest Composite Technologies, LLC, acquired on August 31, 2018, acquiring 100 percent of the equity interest in Kemeera, LLC d/b/a FATHOM (“FATHOM”) on September 23, 2019, and acquiring 100 percent of the equity interest in ICO Mold, LLC on December 2, 2019, as further described in Note 3.

Incodema Holdings was formed on July 15, 2020 as a limited liability company in accordance with the Delaware Act for the purpose of acquiring 100 percent of the equity interest in Incodema, LLC and Newchem, LLC on July 27, 2020, acquiring Dahlquist Machine, LLC on December 15, 2020, acquiring Majestic Metals, LLC on December 17, 2020 and acquiring Mark Two Engineering, LLC on December 18, 2020, as further described in Note 3.

On April 30, 2021, CORE completed a reorganization whereby the interests in both MCT Holdings and Incodema Holdings were contributed to the Company. As such, the Company determined that the financial statements being presented should be the consolidated financial statements of the Company, inclusive of its wholly owned subsidiaries MCT Holdings and Incodema Holdings, with Incodema Holdings being reflected in the consolidated financial statements effective as of July 27, 2020, or the date it came under common control with MCT Holdings. Accordingly, the contingently redeemable Series A Preferred Units, members’ equity, and earnings per unit of the Company is retrospectively presented on a consolidated basis in these consolidated financial statements

The Company and its subsidiaries offer prototyping and low-volume services across a variety of in-house additive manufacturing technologies, as well as precision sheet metal and finishing services ranging from prototype through mid-volume production including internal sheet metal cutting and forming solutions, as well as chemical etching for customers in the aerospace and defense, electronics, medical, automotive, and various other industries. In addition to three-dimensional (“3D”) printing and processing, the Company also offers computer numerical control (“CNC”) machining, injection molding and industrial design capabilities to a diversified customer base in various industries and geographical locations. The Company’s principal operations are located in or in the surrounding areas of Newark, New York; Ithaca, New York; Denver, Colorado; Miami, Florida; Minneapolis, Minnesota; Oakland, California; Toledo, Ohio; Hartland, Wisconsin; Seattle, Washington; and Shenzhen, China.

Going Concern

In accordance with U.S. GAAP, the Company is required to evaluate whether there are conditions or events that exist as of the date of issuance of these consolidated financial statements that raise doubt as to the Company’s ability to continue as a going concern within the twelve months following issuance.

On April 30, 2021, the Company completed a financing transaction whereby it issued a $172,000 term loan due April 2022 (the “2021 Term Loan”) in order to finance the acquisitions of Centex Machine and Welding, Inc.

F-70

(“Centex”), Laser Manufacturing, Inc. (“Laser”), Sureshot Precision, LLC d/b/a Micropulse West (“Micropule West”), and Precision Process Corporation (“PPC”), as well as to refinance the Company’s existing debt, as described in Note 8.

As the Company does not have sufficient cash on hand and cash flow from operations to repay the 2021 Term Loan, the maturity of the 2021 Term Loan raises substantial doubt about our ability to continue as a going concern within the next twelve months. If we are unable to repay, refinance or restructure our 2021 Term Loan, our assets may not be sufficient to repay in full the amounts owed.

To address the upcoming maturity of the 2021 Term Loan, the Company has entered into a new credit facility with its existing creditors (the “New Credit Agreement”). The New Credit Agreement includes a $50,000 revolving credit facility and $125,000 term loan and matures in 2026. The proceeds from these loans will be used to repay the 2021 Term Loan.

The funding of the New Credit Agreement is contingent on the Company closing a definitive business combination with a publicly traded Special Purpose Acquisition Company (“SPAC”) before April 9, 2022 (the “SPAC Transaction”). In addition, the cash proceeds of such SPAC Transaction must be in excess of $313,000, or a lesser amount if mutually agreed by the Company and the SPAC.

The Company intends to use the proceeds from the New Credit Agreement to repay the 2021 Term Loan. If the SPAC Transaction is not completed prior to April 9, 2022, the Company will not receive any funds nor incur any indebtedness from the New Credit Agreement. Given the SPAC Transaction will be subject to regulatory and market conditions, approval by a SPAC’s shareholders, and the SPAC securing adequate financing, it is not within the Company’s control and therefore cannot be deemed probable as of the issuance of these consolidated financial statements. As a result, the Company has concluded that management’s plans described above do not alleviate substantial doubt about the Company’s ability to continue as a going concern for the next twelve months.

The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. Accordingly, the financial statements have been prepared on a basis that assumes the Company will continue as a going concern and which contemplates the realization of assets and satisfaction of liabilities and commitments in the ordinary course of business.

Note 2 — Significant Accounting Policies

Basis of Presentation of the Consolidated Financial Statements

The consolidated financial statements of the Company are comprised of the Company’s subsidiaries from the date on which they were acquired. Each subsidiary is wholly owned by either MCT Holdings or Incodema Holdings, both of which are wholly owned by the Company. The Company’s subsidiaries include: Midwest Composite Technologies, LLC (a Wisconsin Limited Liability Company); Kemeera LLC (a California Limited Liability Company); ICO Mold, LLC (a Delaware Limited Liability Company), Incodema, LLC (a New York Limited Liability Company); Newchem, LLC (a New York Limited Liability Company); Dahlquist Machine, LLC (a Minnesota Limited Liability Company); Majestic Metals, LLC (a Colorado Limited Liability Company); and Mark Two Engineering, LLC (a Florida Limited Liability Company).

The Consolidated Financial Statements as of December 31, 2020 and 2019 have been prepared in accordance with accounting principles generally accepted in the United States of America. All material intercompany accounts and transactions have been eliminated in consolidation.

F-71

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus as a “pandemic”. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the Consolidated Financial Statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the Consolidated Balance Sheet dates, as no triggering events or changes in circumstances had occurred as of year-end; however, due to uncertainty surrounding the situation, and specifically as it pertains to the current global supply chain disruptions, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

Correction of an Immaterial Error

The Consolidated Balance Sheet as of December 31, 2020 includes the correction of an immaterial error related to contingent consideration. The correction relates to a reclassification of certain amounts between assets and liabilities comprised of a decrease in (short-term) contingent consideration of $8,726, a decrease to accounts receivable of $101, and decrease to other current assets of $144, a decrease to property and equipment, net of $418, a decrease to other non-current assets of $48, an increase to accounts payable of $253, an increase of $389 to other non-current liabilities, and an increase to long-term contingent consideration of $7,373.

Cash and Cash Equivalents

Cash and cash equivalents include cash and other short-term investments with original maturities of three months or less at the date of purchase. The Company maintains cash in bank deposit accounts which at times may exceed federally insured deposit limits. The Company has not experienced any losses on such accounts and considers such associated credit risk to be immaterial to the Company’s financial statements.

Credit Risk, Major Customers, and Suppliers

The Company extends trade credit to its customers on terms that are generally practiced in the industry. During the years ended December 31, 2020 and 2019, the Company did not have any customers that accounted for more than 10% of revenue. During the years ended December 31, 2020 and 2019, approximately 19% and 12%, respectively, of inventory purchases were from a single related party supplier, Fathom Precision International Ltd. See Note 15.

Trade Accounts Receivable, Unbilled Revenue and Allowance for Doubtful Accounts

Accounts receivable are stated at net invoice amounts. Unbilled revenue represents receivables due from customers as either the performance obligation has been completed for revenue recognized over time or the product has shipped and the customer invoice has yet to be generated. The balance in unbilled revenue, included in accounts receivable, was $173 and $634 as of December 31, 2020 and 2019, respectively. An allowance for doubtful accounts is established based on a specific assessment of all invoices that remain unpaid following normal customer payment periods. In addition, a general valuation allowance is established for the remaining accounts receivable that have not been specifically assessed based on historical loss experience as well as geographic and general economic conditions. All amounts deemed to be uncollectible are charged against the allowance for doubtful accounts in the period that determination is made. The allowance for doubtful accounts on accounts receivable balances was $649 as of December 31, 2020 and $386 as of December 31, 2019.

Inventory

Inventory is stated at the lower of cost or net realizable value (“NRV”), with NRV based on selling prices in the ordinary course of business, less costs of completion, disposal, and transportation. Costs are determined on the first-in, first-out (“FIFO”) method.

F-72

Property and Equipment

Property and equipment are recorded at cost or fair value, if acquired in the business combinations, as described in Note 3. The straight-line method is used for computing depreciation and amortization. Assets are depreciated over their estimated useful lives. The cost of leasehold improvements are amortized over the lesser of the length of the related leases or the estimated useful lives of the assets. Costs of maintenance and repairs are charged to expense when incurred.

Asset	Useful Lives (In Years)
Property and leasehold Improvements	4-20
Machinery & equipment	1-6
Furniture & fixtures	1-7
Vehicles and equipment	1-4
Capitalized software	1-2

Goodwill

The Company recognizes goodwill in accordance with ASC 350, Intangibles—Goodwill and Other. Goodwill is the excess of costs of an acquired entity over the amounts assigned to assets acquired and liabilities assumed in a business combination. Goodwill is not amortized. Goodwill is tested for impairment annually on October 1st of each year and is tested for impairment between annual tests if an event occurs or circumstances change that would indicate the carrying amount may be impaired. During the years ended December 31, 2020 and 2019, the Company performed a quantitative analysis, which indicated that no impairment charges for goodwill were required to be recognized.

Intangible Assets

Acquired intangible assets subject to amortization are stated at cost and are amortized using the straight-line method over the estimated useful lives of the assets. Intangible assets that are subject to amortization are reviewed for potential impairment whenever events or circumstances indicate that carrying amounts may not be recoverable. During 2019 and 2020 there were no impairments of intangible assets.

Foreign Currency Exchange and Translation

The expression of assets and liabilities in a foreign currency amount gives rise to exchange gains and losses when such obligations are paid in United States dollars. Foreign currency exchange rate adjustment (i.e., differences between amounts recorded and actual amounts owed or paid) are reported in the Consolidated Statements of Comprehensive Loss as foreign currency fluctuations occur. Foreign currency exchange rate adjustments are reported in the Consolidated Statements of Cash Flows using the exchange rates in effect at the time of the cash flows. Adjustments for the years ended December 31, 2020 and 2019 were immaterial.

Assets and liabilities of the Company’s operations in China are translated into U.S. dollars at the rate of exchange in effect at the close of the period. Income and expenses are translated at an average rate of exchange for the period. The aggregate effect of translating the financial statements is included in other comprehensive loss.

Fair Value Measurements

Accounting standards require certain assets and liabilities be reported at fair value in the financial statements and provide a framework for establishing that fair value. The framework for determining fair value is based on a hierarchy that prioritizes the inputs and valuation techniques used to measure fair value. There are three levels of inputs that may be used to measure fair value:

Fair values determined by Level 1 inputs use quoted prices in active markets for identical assets or liabilities that the Company has the ability to access.

F-73

Fair values determined by Level 2 inputs use other inputs that are observable, either directly or indirectly. These Level 2 inputs include quoted prices for similar assets and liabilities in active markets and other inputs such as interest rates and yield curves that are observable at commonly quoted intervals.

Level 3 inputs are unobservable inputs, including inputs that are available in situations where there is little, if any, market activity for the related asset. These Level 3 fair value measurements are based primarily on management’s own estimates using pricing models, discounted cash flow methodologies, or similar techniques considering the characteristics of the asset.

In instances whereby inputs used to measure fair value fall into different levels in the above fair value hierarchy, fair value measurements in their entirety are categorized based on the lowest level input that is

significant to the valuation. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

Debt Issuance Costs

Debt issuance costs were incurred by the Company in connection with obtaining the debt to finance the acquisitions disclosed in Note 3. If such financing is settled or replaced prior to maturity with debt instruments that have substantially different terms, the settlement is treated as an extinguishment and the unamortized costs are charged to gain or loss on extinguishment of debt. If such financing is settled or replaced with debt instruments from the same lender that do not have substantially different terms, the new debt agreement is accounted for as a modification of the prior debt agreement and the unamortized costs remain capitalized, the new original issuance discount costs are capitalized, and any new third-party costs are charged to expense. These costs are recorded as a reduction in the recorded balance of the outstanding debt. The costs are amortized over the term of the related debt and reported as a component of interest expense by using the straight-line method which is not materially different than the effective interest method.

Revenue Recognition

On January 1, 2019, the Company adopted ASC 606, Revenue from Contracts with Customers, using the modified retrospective approach. Most of the Company’s revenue has one performance obligation and is recognized on a point-in-time basis upon shipment. The majority of the Company’s injection molding contracts have multiple performance obligations including one obligation to produce the mold and sample part and a second obligation to produce production parts. For injection molding contracts with multiple performance obligations, the Company allocates revenue to each performance obligation based on its relative standalone selling price and recognizes revenue for each performance obligation on a point-in-time basis upon shipment. We generally determine standalone selling price based on the price charged to customers. The Company’s payments terms are consistent with industry standards and never exceed 12 months.

Income Taxes

As a limited liability company, the Company has elected to report as a partnership for federal and state income tax purposes at a consolidated level. Consequently, federal income taxes are not payable or provided for by the Company. Members are taxed individually on their pro-rata ownership share of the Company’s earnings. The Company’s net income or loss is allocated among the members in accordance with the Company’s operating agreement. The Company is subject to certain state and local income and franchise taxes, which are included in the Consolidated Statements of Comprehensive Loss as other income, net. In addition, MCT Holding’s wholly owned subsidiary, ICO Mold (Shenzhen), LLC, is subject to income within the jurisdiction of the People’s Republic of China. Foreign income tax expense was insignificant during both the year ended December 31, 2020 and the year ended December 31, 2019.

F-74

Other Comprehensive Loss

Accounting principles generally require that recognized revenue, expenses, gains and losses be included in net income. Certain changes in assets and liabilities, however, such as foreign currency translation adjustments, are reported as a direct adjustment to the equity section of the Consolidated Balance Sheets. Such items, along with net income, are considered components of comprehensive loss.

Use of Estimates

The preparation of Consolidated Financial Statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Recent Accounting Pronouncements

The Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases, which will supersede the current lease requirements in ASC 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The new lease guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a modified retrospective transition method to either the beginning of the earliest period presented or the beginning of the year of adoption. The Company is still evaluating which method it will apply. The new lease standard is expected to have a significant effect on the Company’s financial statements as a result of the Company’s operating leases, as disclosed in Note 9, that will be reported on the balance sheet at adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

The FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326), which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses on certain types of financial instruments, including trade receivables and available for sale debt securities. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, with early adoption permitted. The Company continues to evaluate the impact of this ASU on its Consolidated Financial Statements.

The FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract, which requires a customer in a cloud computing arrangement that is a service contract to follow the internal-use software guidance in ASC Topic 350-40 to determine which implementation costs to defer and recognize as an asset. ASU 2018-15 will be effective for annual periods, and interim periods within annual periods, beginning after December 15, 2020 and interim periods within annual periods beginning after December 15, 2021. Early adoption is permitted, including adoption in any interim period, for all entities. The Company continues to evaluate the impact the adoption of ASU 2018-15 will have on its Consolidated Financial Statements.

The FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (ASU 2019-12). ASU 2019-12 attempts to simplify aspects of accounting for franchise taxes and enacted changes in tax laws or rates and clarifies the accounting for transactions that result in a step-up in the tax basis of goodwill. ASU 2019-12 is effective for fiscal years beginning after December 15, 2020, including interim periods within that fiscal year. The Company does not anticipate any material impact on the Company’s Consolidated Financial Statements upon adoption.

F-75

The FASB issued ASU 2020-04, Facilitating the effects of Reference Rate Reform on Financial Reporting, which provide optional expedients and exceptions for applying generally accepted accounting principles (“GAAP”) to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The amendments in this Update apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. The expedients and exceptions provided by the amendments do not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022, that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The amendments in this Update are effective for all entities as of March 12, 2020 through December 31, 2022. The Company continues to evaluate the impact of the adoption of ASU 2020-04 will have on its Consolidated Financial Statements.

Note 3 — Business Combination

The transactions below met the requirements to be considered a business combination under ASC 805. The accounts, affected for preliminary adjustments to reflect fair market values assigned to assets purchased and liabilities assumed, and results of operations, are included in the Company’s Consolidated Financial Statements from the date of acquisition. The Company has allocated the purchase price to the tangible and identifiable intangible assets based on their estimated fair market values at the acquisition date as required under ASC 805. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets was recorded as goodwill.

Acquisition of Kemeera, LLC. d/b/a FATHOM

MCT Group Holdings, LLC completed an acquisition of Kemeera, LLC d/b/a FATHOM (“FATHOM”) on September 23, 2019 in which it acquired 100 percent of the membership interest of FATHOM. FATHOM provides a mix of prototype and production manufacturing services in addition to development and engineering services. FATHOM’s prototype services include 3D printing and additive manufacturing, CNC machining, urethane casting, tooling, injection molding, and part assembly and finishing. Additional services include industrial and engineering support and contract research and development projections. The primary reason for the acquisition was to expand the Company’s capabilities in 3-D printing and manufacturing and expand its customer base of high-quality manufacturing and industrial technology companies in North America.

The transaction was accounted for using the acquisition method of accounting and the fair value of the total purchase consideration transferred consisted of the following:

Note 4 — Revenue

The Company accounts for revenue in accordance with ASC 606, Revenue from Contracts with Customers, which the Company adopted on January 1, 2019, using the modified retrospective method. The adoption of ASC 606 did not have a material impact on our Consolidated Financial Statements.

Revenue is recognized in five steps. The Company identifies the contract with the customer, identifies the performance obligations in the contract, determines the transaction price, allocates the transaction price to the performance obligations, and recognizes revenue when (or as) each performance obligation is satisfied. Collectability is a required component of a valid contract. The Company assesses collectability based on a number of factors, including the customer’s past payment history and current creditworthiness. If collectability is not considered probable at inception, the Company will not have a valid contract.

The Company provides high quality, advanced rapid prototyping, precision manufacturing and finishing services in low-to-mid volume production scenarios. The Company’s suite of on-demand digital manufacturing services includes additive manufacturing, machining, and molding technologies as well as sheet metal cutting, etching, and forming solutions for customers in the aerospace and defense, electronics, medical, automotive, consumer, and industrial industries, among others. As a result, the majority of revenue recognized in a reporting period is based on completed, invoiced contracts.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in ASC 606. The majority of the Company’s Additive Manufacturing, CNC Machining, Urethane Casting, Precision Sheet Metal, and Chemical Etching contracts have a single performance obligation. The majority of the Company’s injection molding contracts have multiple performance obligations including one obligation to produce the mold and sample part and a second obligation to produce production parts. For injection molding contracts with multiple performance obligations, we allocate revenue to each performance obligation based on its relative standalone selling price. We generally determine standalone selling price based on the price charged to customers.

Below is a listing of the Company’s major sales product lines and their recognition patterns:

Additive Manufacturing

Our Additive Manufacturing product line utilizes plastic and metal 3D printing technology to provide a wide-variety of high-quality, precision rapid prototyping solutions and low volume production. Performance obligations are dictated by the contractual shipping terms agreed upon by the Company and its customers. Revenue is recognized at a point in time based on shipping terms.

Injection Molding

Our Injection Molding product line uses our 3D CAD machining technology for the automated design and manufacture custom tooling and small to medium part production runs. Tooling and sampling production and part production runs are recognized at a point in time based on shipping terms.

Computer Numerical Control (“CNC”) Machining

Our CNC Machining product line delivers high-quality precision parts by way of modern machining methods to drive more outstanding results. Performance obligations are dictated by the contractual shipping terms agreed upon by the Company and its customers. Revenue is recognized at a point in time based on shipping terms.

F-84

Precision Sheet Metal

Our Precision Sheet Metal product line includes efficient quick-turn custom sheet metal parts from prototype to mid-volume production runs. In addition, the Precision Sheet Metal product line includes chemical etching. Chemical etching provides customers the ability to quickly make complex precision parts and decorative items – beyond hard tool capability and without the cost – fabricated in dead soft or full hard material without burrs or metal distortion. Performance obligations for the Precision Sheet Metal product line are dictated by the contractual shipping terms agreed upon by the Company and its customers. Revenue is recognized at a point in time based on shipping terms.

Other Product Lines

Urethane Casting

Our Urethane Casting product line is most commonly used during prototyping, including finished looking parts for final tests and presentations, and low volume production. Performance obligations are dictated by the contractual shipping terms agreed upon by the Company and its customers. Revenue is recognized at a point in time based on shipping terms.

The remaining other product lines include, but are not limited to, in-house assistance, and industrial design, engineering services, finishing and assembly services, and customer crating and packaging. Revenue is recognized over time for professional services based on hours incurred as periodically invoiced and at a point in time based on shipping terms for the other manufacturing-related services. Services related revenues are immaterial to the Company’s consolidated financial statements.

Revenue by product line for the years ended December 31, 2020 and 2019 was as follows:

	Year ended December 31,

Total revenue	$	61,289	$	20,618

The Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within selling, general, and administrative expenses.

The Company’s deferred revenue balance as of December 31, 2020 and 2019 is $1,210 and $368, respectively. Deferred revenue is the result of billings in excess of revenue being recognized and is recorded in other current liabilities on the Company’s balance sheet. Deferred revenue is recognized fully in the following period due to the short-term nature of the customer contracts.

Note 5 — Inventory

Inventory consists primarily of finished goods, raw materials and work in process, which are recorded at the lower of cost or net realizable value, which approximates first-in, first-out (“FIFO”) cost.

On December 16, 2020, the Company entered into the first amendment to the 2020 Credit Facility. Pursuant to the amendment, the availability on the delayed draw term loan was increased to $40,500. The Company is charged a Commitment Fee of 0.5% for the initial 6 month period and 1.0% following the six month period on the unused portion of the delayed draw term loan. The amendment resulted in issuance costs of $692 of which

F-88

$660 were capitalized and $32 were expensed. Borrowings on the delayed draw term loan amount were not drawn until acquisitions of Dahlquist, Mark Two, and Majestic Metals beginning mid-December as described in Note 3. The 2020 DDTL was fully drawn as of December 31, 2020.

The 2020 Credit Facilities mature on July 27, 2026.

Paycheck Protection Program Loan

During the year ended December 31, 2020, the Company received a Paycheck Protection Program (“PPP”) loan in the amount of $1,624 through the Small Business Administration (“SBA”) under the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. At the time of submission of the application and at the time the PPP Loan was funded, the Company satisfied and the Company continues to satisfy all of the applicable criteria for the PPP Loan set forth in the Small Business Act (15 U.S.C. 636(a)) and the CARES Act. Under the terms of this program, the loan may be fully or partially forgiven if the loan proceeds are spent on qualifying expenses and if staffing level and salary maintenance requirements are met. The Company was permitted to use the funds on qualifying expenses over a covered period of up to 24 weeks. At the conclusion of the covered period, any balance that is not forgiven by the SBA will be repaid within two years from issuance date with interest accruing at a rate of 1.0 percent, with monthly payments of principal and interest beginning ten months after the conclusion of the covered period.

Additionally, the Company assumed additional PPP loans during the year ended December 31, 2020 in the amount of $991 through the acquisitions of Dahlquist and Mark Two as discussed in Note 3. For PPP loans assumed through these acquisitions (the “Assumed PPP Loans”), the applicable seller agreed to indemnify the Company of all losses which the Company may suffer, sustain or become subject to as a result of or related to any applicable Assumed PPP Loan. As such, an indemnification asset of $991 was recorded as of the acquisition of each company and the balance thereof is included in other assets.

Any request for forgiveness is subject to review and approval by the lender and the SBA, including review of qualifying expenditures and staffing and salary levels.

Subsequent to December 31, 2020, the Company has submitted requests for forgiveness. The Company expects to receive forgiveness for the entire loan balance in 2021. There can be no assurance that any portion of the PPP loans will be forgiven.

Note 9 — Operating Leases

The Company accounts for leases in accordance with ASC 840, Leases. The Company enters into leases in the normal course of business primarily for office space, manufacturing facilities and certain company vehicles and equipment and finance leases for certain company equipment. The Company is obligated under non-cancellable lease agreements for certain facilities, which frequently include renewal options and escalation clauses. For leases that contain predetermined fixed escalations, we recognize the related rent expense on a straight-line basis and record the difference between the recognized rent expense and amounts payable under the lease as Deferred Rent. The Company includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Company will exercise the option. The Company’s leases have remaining lease terms ranging from 2 to 7 years.

The Company determines if an arrangement is a lease at inception. Operating leases are off balance sheet arrangements with rent expense included in Cost of revenue and Selling, general and administrative in the Consolidated Statements of Comprehensive Loss. Future noncancelable operating lease commitments are as follows (in thousands):

Class A Preferred Units		702,493		702,493	$	45.32	$	31,836	$	3,209	$	35,045

The rights and preferences of holders of the redeemable convertible preferred stock are as follows:

Dividends

The Company’s Class A Contingently Redeemable Preferred Units (“Class A Preferred Units”) were issued at $100 par per unit and accumulate a preferred return at 8.0 percent, compounded on the first business day of each calendar quarter in respect of the prior calendar quarter.

The Company does not record any changes in carrying value of the Class A Preferred Units due to cumulative unpaid dividends. Dividends are accrued at the time they are declared by the Company’s Board of Managers. No dividends were declared or paid on the Class A Preferred Units in the years ended December 31, 2020 and December 31, 2019.

Voting Rights

Class A Contingently Redeemable Preferred unitholders are not entitled to voting rights.

Redemption

The Company shall make a distribution to each of the Class A Preferred unitholders in an amount equal to the aggregate Class A Preferred unpaid yield and Class A Preferred unreturned capital, effective upon the

F-91

occurrence of any of the following events (referred to as a “redemption event”): the sale, lease, license, transfer, conveyance or other disposition of a majority of the assets of the subsidiaries of the Company; the merger, consolidation, recapitalization, reorganization or sale of securities; any merger, consolidation, joint venture or other business combination pursuant to which the Company is combined with that of a special purpose acquisition company or other blank-check company which has a class of equity securities publicly listed on a national securities exchange; or a Public Offering with respect to Holdings LLC or any of its Subsidiaries, the reorganization of Holdings LLC or any of its Subsidiaries from a limited liability company to a corporation (whether or not in connection with a Public Offering) or an election by Holdings LLC to be treated as a corporation for U.S. federal income tax purposes.

As a result, the Class A Preferred Units are recorded separately from members’ equity because they are redeemable upon the occurrence of redemption events that are considered not solely within the Company’s control.

The Company expensed issuance costs related to the Class A Preferred Stock as incurred for the twelve months ended December 31, 2020 and December 31, 2020. The amounts expensed were immaterial to the Company’s financial statements.

Note 13 — Members’ Equity

The Company’s equity consists of Class A Common Units and Class B Common Units.

See Note 3 for member units issued as part of business combination transactions in 2020 and 2019.

Unit holders of Class A common units Class B common units share equally in the undistributed income of the Company after consideration of the cumulative unpaid dividends related to the Class A Preferred Units. Allocations and distributions to incentive units are subject to certain participation thresholds set by the managers of Company. Unit holders of Class A Common Units are entitled to one vote per Class A Common Unit held and unit holders of Class B Common Units are not entitled to vote.

The following table represents a summary of the Company’s Member’s Equity as of December 31, 2020 and December 31, 2019:

	December 31, 2020		December 31, 2019

Note 14 — Earnings Per Unit

Basic and diluted earnings per common unit is presented in conformity with the two-class method required for participating securities. The holders of the Company’s Class A Preferred Units are entitled to accrue cumulative dividends at the rate of 8% per annum. The Company considered its contingently redeemable preferred units to be participating securities and, in accordance with the two-class method, earnings allocated to preferred units have been excluded from the computation of basic and diluted net income or loss per common unit.

F-92

Basic net income (loss) per unit is computed based on the weighted average number of common units outstanding. Diluted net income (loss) per unit is computed based on the weighted average number of common units outstanding, increased by the number of any additional units that would have been outstanding had any potentially dilutive common units been issued and reduced by the number of units the Company could have repurchased from the proceeds from issuance of the potentially dilutive units. The Company had no dilutive instruments outstanding as of December 31, 2020 and December 31, 2019. As a result, basic and diluted earnings per units are the same as of December 31, 2020 and December 31, 2019.

The Company’s Class A and Class B common units participate equally in the Company’s undistributed earnings. As such, the Company’s undistributed earnings are allocated pro-rata to the Class A and Class B common units based on the weighted Class A common and Class B common units outstanding in 2020 and 2019 such that earnings per unit for Class A and Class B common units are the same in each period.

The computation of basic and diluted earnings per Class A common and Class B common unit for all periods disclosed was calculated using the shares issued to previous unitholders in connection with the Company’s reorganization on April 30th, 2021 which is further described in Note 1, Note 2, and Note 20.

Note 16 — Share Based Compensation

The Company has two share-based compensation plans as described below. Total compensation cost that has been charged against income for those plans was $34 and $21 for 2020 and 2019, respectively.

MCT Holdings 2019 Phantom Equity Bonus Plan (the “MCT Plan”) and Incodema Holdings’ 2020 Phantom Equity Bonus Plan (the “Incodema Plan”), both of which are unitholder approved, permit the grant of phantom units to eligible employee recipients for up to 10,000 phantom units for each respective plan. The awards were established for the purpose of providing recipients with a financial incentive through the opportunity to earn bonus compensation tied to appreciation in the equity value of MCT Holdings and Incodema Holdings, respectively.

The awards under both plans have two vesting components: (1) time vesting and; (2) performance vesting. A quarter (25%) of the awards vest ratably, in equal installments, on each of first four employment commencement date anniversaries or vest in full upon the consummation of the sale of the Company. The remaining three-quarters (75%) of the awards vest if the MCT Holdings and Incodema Holdings investors realize a Multiple on Invested Capital (“MOIC”) of at least 2x upon the consummation of such sale of each company.

The award units are representative of a percentage of the proceeds from the sale, allowing for up to 10,000 units to be awarded and 10% of the value of the sale to be paid-out so long as the investors realize a MOIC of at least 2x for each respective company. The time vesting component, or service condition, is designed to retain talent for the lesser of four years or the consummation of the sale. As such, as long as grantees are in good standing with the company upon a sale, they are entitled to a minimum of a quarter (25%) of the units granted and the resulting payout regardless of the performance condition (outside of the Sale) being met.

Awards will be settled in cash based on the percentage of proceeds they represent in accordance with the outlined calculations in the plans. However, the administrator, in its sole discretion, can determine if any or all proceeds payable are to be in a form other than cash or marketable securities. Awards shall be payable in the same mix of consideration received by all such holders of equity in the company. If the administrator determines to pay such awards in a form other than cash, then the fair market value of such consideration shall be determined by the administrator in good faith.

The fair value of awards granted was determined using the Black-Scholes pricing model and the following weighted-average assumptions in the table below as of the grant date. Expected volatility is based on the historic volatility of our guideline companies, which we believe best represent our company.

	2020			2019
Risk-free interest rate		0.28	%		2.24	%
Expected Term		4.65			4.47
Expected Volatility		76.67	%		73.55	%
Expected dividend yield		0.00	%		0.00	%

The Company’s accounting policy is to record forfeitures as they occur, however there were no forfeitures in the years ended December 31, 2020 and 2019.

As of December 31, 2020, there was $554 of total unrecognized compensation cost related to the Phantom Units granted under the Plan. The cost is expected to be recognized over a weighted average period of 2.8 years. The total fair value of shares vested during the years ended December 31, 2020 was $34. No cash payments related to the Phantom Units were made during 2020.

No cash payments related to the Phantom Units were made during 2019.

Note 17 — Fair Value Measurement

The Company used the following methods and significant assumptions to estimate fair value:

Contingent Consideration: The fair values for earnouts payable are determined by using a discounted cash flow (“DCF”) approach with unobservable inputs and is classified as a Level 3 liability in the fair value hierarchy. The Company’s assessment of the significance of particular inputs to these fair value measurements requires judgment and considers factors specific to each asset or liability.

Assets and liabilities measured at fair value on a recurring basis, are summarized below:

	Fair Value Measurement at December 31, 2020 Using:
	Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Total
Contingent consideration	$	—	$	—	$	11,439	$	11,439

Contingent consideration	$	11,439

The valuation techniques used to determine the fair value of the contingent consideration as of December 31, 2020 included a combination of discounted cash flow, Black-Scholes-Merton model, and Monte Carlo simulation. The significant unobservable inputs used in the calculation of fair value include the discount rate, volatility, and credit spreads. The discount rates range from 2.9% to 18.8%, the volatility ranges from 15.3% to 80.2%, and the credit spreads range from 5.2% to 6.6%.

Note 18 — Commitments and Contingencies

PPP Loan Forgiveness and Indemnification Assets

As part of the Coronavirus Aid, Relief, and Economic Security Act of 2020 (“CARES Act”), certain companies were eligible to receive a Paycheck Protection Program (“PPP”) Loan, which is forgivable under the CARES Act as long as the loan proceeds are used for specific purposes. As disclosed in Note 3, the Company acquired certain businesses which had PPP Loan balances outstanding at the time of acquisition, and thus assumed the applicable PPP Loans. As part of these acquisitions, the Company agreed to take all actions reasonably required to pursue forgiveness of the loans in accordance with the CARES Act. In the event the Assumed PPP Loans are not approved for forgiveness by the U.S. Small Business Administration (“SBA”), the Company has the contractual right to require repayment from the former owners of the acquired businesses that received such loans. As of each acquisition date, an amount equal to the then outstanding principal balance of the Assumed PPP Loans was disbursed to an escrow account to be held until such time that the SBA determines whether the Assumed PPP Loans will be forgiven or not. In such case that the loan is forgiven by the SBA, the funds held in escrow will be distributed to the respective former owners of the applicable acquired business. In such case that the loan is not forgiven, the funds held in escrow will be distributed to the Company within 10 days of notice of the SBA’s decision not to forgive the Assumed PPP Loan. The term of the contractual guarantee from the sellers is from the date of acquisition until the date of the SBA’s forgiveness decision. The ultimate date of the SBA’s forgiveness decision is not known or knowable as of the date of the financial statements, but is reasonably expected to occur in fiscal 2021.

As a result of this contractual right to reimbursement, the Company is indemnified for the principal balance of the Assumed PPP Loans, either through forgiveness from the SBA or through reimbursement from the sellers. As such, the Company has recorded an indemnification asset equal to the principal balance of the PPP Loans assumed.

The total indemnification assets are recorded as other assets on the Company’s balance sheet as of December 31, 2020 in the amount of $991 as an offset to the Assumed PPP Loans acquired which are held at the following consolidated subsidiaries:

◾ Mark Two — $473 PPP Loan received on April 17, 2020.

◾ Dahlquist — $518 PPP loan received on April 21, 2020.

Litigation

The Company is subject to various claims and lawsuits that arise in the ordinary course of business. It is the opinion of management that the disposition or ultimate resolution of such claims and lawsuits will not have a material effect on the consolidated financial position of the Company.

F-96

Additionally, the Company is a defendant in a hybrid collective/class action complaint filed by one of its former employees for alleged violations of the Fair Labor Standards Act and Wisconsin wage and hour law. Management notes that at this stage in the proceedings, no opinion as to the probable outcome can be offered. The parties have agreed to engage in settlement discussions and at this time an estimate of the settlement is unknown.

Note 19—Segment Reporting

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker in deciding how to allocate resources and in assessing operating performance. In consideration of Accounting Standards Codification (ASC) 280, “Segment Reporting,” we are not organized around specific services or geographic regions. Our chief operating decision maker uses consolidated financial information to evaluate our performance, which is the same basis upon which the results and performance of the Company are communicated to the Board of Directors. The chief operating decision maker bases all significant decisions regarding the allocation of our resources on a consolidated basis. Based on the information described above and in accordance with the applicable literature, management has concluded that we are organized and operate as one operating and reportable segment.

Notes to Combined Financial Statements

June 30, 2020 and 2019

Note 1 — Nature of Business

Incodema, Inc. (Incodema) began operations in 2001 and is a prototype and short run sheet metal stamping provider which produces high quality items as sheet metal stampings, intricate metal formings, short run production stamping, laser cutting, and photo chemical machining (PCM).

NewChem, Inc. (NewChem) began operations after acquiring the assets of another entity on September 7, 2011. NewChem is a photochemical milling company located in Newark, NY. The process involves coating material specified with a light sensitive polymer, imaging with a photo tool using UV light, developing and then chemically etching.

Incodema and NewChem are collectively referred to as the “Company” throughout the combined financial statements.

Note 2 — Significant Accounting Policies

Basis of Presentation

The unaudited combined financial statements of the Company have been prepared in accordance with accounting principles generally accepted accounting principles in the United States of America (U.S. GAAP) for interim financial information and with the instructions to Article 10 of Regulation S-X. In the opinion of management, all adjustments necessary for a fair presentation have been included and are of a normal recurring nature. Interim results are not necessarily indicative of the results that may be expected for the year.

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from those estimates.

The unaudited combined interim financial statements and footnotes should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2019.

Principles of Combination

The accompanying combined financial statements include the accounts of Incodema and NewChem, which are under common ownership. All material intercompany accounts and transactions have been eliminated in combination.

Cash Equivalents

For the purpose of the accompanying financial statements, the Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The carrying amount reported in the balance sheet for cash and cash equivalents approximates fair value due to the short-term nature of these investments.

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company places its temporary cash investments with high credit quality financial institutions and attempts to limit its amount of credit exposure to any one financial institution. However, at various times during the period, the Company’s cash balances exceeded the federally insured limits.

F-103

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

June 30, 2020 and 2019

Accounts Receivable

The Company’s accounts receivable and unsecured customer obligations due under normal trade terms ordinarily requiring payment within (30) days from the invoice date. The company often has receivables paid net ninety (90) days for both automotive and aerospace industries. Accounts receivable are stated at the amount billed to the customer. The company does not accrue interest on accounts receivable. As of June 30, 2020 and December 31, 2019, management believed that all accounts receivable would be collected and as such did not record an allowance.

Inventory

Inventory is stated at the lower of cost or net realizable value (NRV), with NRV based on selling price in the ordinary course of business, less costs of completion, disposal, and and transportation. Cost are determined on a first-in, first-out (FIFO) method.

Property and Equipment

Property and equipment are recorded at cost. Both straight-line and accelerated methods are used for computing depreciation and amortization. Assets are depreciated over their estimated useful lives. The cost of leasehold improvements is depreciated over the lesser of the length of the related leases or the estimated useful lives of the assets. Costs of maintenance and repairs are charged to expense when incurred.

Goodwill

The recorded amounts of goodwill from prior business combinations are based on management’s best estimates of the fair values of assets acquired and liabilities assumed at the date of acquisition. Goodwill is not amortized, but rather is assessed at least on an annual basis for impairment.

No impairment charge was recognized during the six-months ended June 30, 2020 and 2019.

Employee Stock Ownership Plan

Compensation expense is recognized for the Employee Stock Ownership Plan (ESOP) equal to the average fair value of shares committed to be released for allocation to participant accounts. Any difference between the average fair value of shares committed to be released for allocation and the ESOP’s original acquisition cost is charged or credited to stockholders’ equity (additional paid-in capital). The cost of unallocated ESOP shares (shares not yet released for allocation) is reflected as a reduction of stockholders’ equity.

Revenue and Cost Recognition

The Company offers precision manufacturing and finishing services ranging from prototype through high-volume production, including internal sheet metal cutting and forming solutions, chemical etching, and medical device production for customers in the aerospace and defense, electronics, medical, automotive, and various other industries. The parts are shipped upon receipt of purchase orders and completion of the manufacturing process to customers who are located primarily in the United States.

During the six months ending June 30, 2020 and 2019, the Company recognized revenue from contracts with customers of $9,954,911 and $7,562,253, respectively. All revenue was recognized at a point in time. The Company did not recognize any contract assets or liabilities.

F-104

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

June 30, 2020 and 2019

Timing of Satisfaction

Contract terms do not include cancellation provisions that would result in an enforceable right to payment for performance completed to date, and, as a result, revenue is recognized at a point in time.

The Company satisfies its performance obligations as goods are produced or goods are delivered.

Parts are typically shipped “FOB Shipping Point” based on the purchase order. For parts shipped as FOB Destination, ownership of goods in transit remains with the Company, and the Company bears the associated risks (e.g., loss, damage, or delay). In other cases, the customer will take delivery directly from the Company’s inventory (“FOB Shipping Point”), at which point ownership and the associated risk pass to the customer.

Contracts with customers usually contain only one performance obligation that is satisfied at point in time. Contracts recognized at a point in time have no satisfied performance obligations that would result in contract assets other than trade accounts receivable.

Determining the Transaction Price

The transaction price of a contract is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer. Transaction prices do not include amounts collected on behalf of third parties (e.g., sales taxes).

To determine the transaction price of a contract, the Company considers its customary business practices and the terms of the contract. For the purpose of determining transaction prices, the Company assumes that the goods or services will be transferred to the customer as promised in accordance with existing contracts and that the contracts will not be canceled, renewed, or modified. All of the Company’s contracts with customers have fixed transaction prices that are denominated in U.S. dollars and payable in cash.

Significant Payment Terms

Payment for goods and services sold by the Company is typically due within 30 days after an invoice is sent to the customer.

Nature of Promises to Transfer

In most cases, goods that the Company contracts to transfer to customers are manufactured by the Company for sale. In no case does the Company act as an agent (i.e., the Company does not provide a service of arranging for another party to transfer goods or services to the customer).

Shipping and Handling

With respect to sales of goods shipped FOB Shipping Point, the Company performs shipping and handling activities after its customers obtain control of the goods in some cases. The Company’s policy is to account for shipping and handling as activities to fulfill its promise to transfer the good (i.e., shipping and handling activities are expensed). With respect to sales of parts that are shipped “FOB Shipping Point,” the Company recognizes revenue before it performs shipping and handling activities, and the costs are accrued at that time.

Income Taxes

Pursuant to provisions of the Internal Revenue Code, the Company has elected to be taxed as an S corporation. Generally, the income of an S corporation is not subject to federal income tax at the corporate level,

F-105

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

June 30, 2020 and 2019

but rather the stockholders are required to include a pro-rata share of the corporation’s taxable income or loss in their personal income tax returns, irrespective of whether dividends have been paid. Accordingly, no provision for federal income taxes has been made in the accompanying financial statements.

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Credit Risk, Major Customers, and Suppliers

In 2020 and 2019, sales to one customer comprised of 31% and 6% of total Company revenues, respectively. Management notes that sales to specific customers tend to be cyclical and customer concentrations frequently shift. In 2020 and 2019, outstanding receivables to one customer comprised of 36% and 16%, respectively.

In 2020 and 2019, purchases from a supplier comprised of 8% and 7% of total Company revenues, respectively. Management toes that purchases from specific customers could cause the Company to experience delays and reduce efficiencies in operations if supplier were to cease supplying services to the Company. In 2020 and 2019, outstanding payables to one customer comprised of 7% and 21%, respectively.

Upcoming Accounting Pronouncements

The Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases, which will supersede the current lease requirements in ASC 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The reporting of lease-related expenses in the statements of operations and cash flows will be generally consistent with the current guidance. The new lease guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a modified retrospective transition method to either the beginning of the earliest period presented or the beginning of the year of adoption. The Company is still evaluating which method it will apply. The new lease standard is expected to have a significant effect on the Company’s financial statements as a result of the Company’s operating leases, as disclosed in Note 10, that will be reported on the balance sheet at adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to-use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU includes changes to the accounting and measurement of financial assets including the Company’s accounts receivable and held-to-maturity debt securities by requiring the Company to recognize an allowance for all expected losses over the life of the financial asset at origination. This is different from the current practice where an allowance is not recognized until the losses are considered probable. The ASU also changes the way credit losses are recognized for available-for-sale debt securities. Credit losses are recognized

F-106

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

June 30, 2020 and 2019

through the recording of an allowance rather than as a write-down of the carrying value. The new guidance will be effective for the Company’s year ending December 31, 2021. Upon adoption, the ASU will be applied using a modified retrospective transition method to the beginning of the earliest period presented. The Company does not believe the adoption of the new standard will have a significant effect on the combined financial statements.

Subsequent Events

The financial statements and related disclosures include evaluation of events up through and including July 28, 2021, which is the date the financial statements were available to be issued.

Incodema sponsors a leveraged employee stock ownership plan (the “ESOP” or the “Plan”) that was established January 1, 2017. Employees are eligible to participate in the plan upon attainment of age 21 and completion of one-thousand (1,000) hours of service in an eligibility computation period. All Employees employed by the Company on January 1, 2017, were immediately eligible to participate in the Plan. The purpose of the Plan is to provide retirement benefits for eligible employees. The Plan is intended to qualify as an employee stock ownership plan under Sections 401(a) and 4975(3)(7) of the Code as well as Section 407(d)(6) of ERISA.

The ESOP originally purchased 43,011 shares of Incodema common stock using proceeds of a $4,000,000 loan issued from Incodema. This ESOP loan bears interest at 3.04 percent per annum, and matures on April 30, 2038. The loan payments are funded through contributions to the Plan made by Incodema.

Notes to Combined Financial Statements

June 30, 2020 and 2019

In accordance with applicable accounting standards, the loan between Incodema and the ESOP is not presented as an asset within the combined balance sheet but rather a contra equity account described as “unearned ESOP shares.” The shares held by the ESOP are allocated to participant accounts, as the repayments are made by the Plan. Shares are released based on debt service paid and allocated to active participants based on a formula of the participants’ pro rata shares of eligible compensation. The unearned ESOP shares account reported as contra equity is reduced as compensation expense is recognized under the Plan.

Upon retirement, the value of the participant’s accrued benefit payable as recalculated as of the most recent valuation date prior to the date of distribution. If the participant chooses to receive their benefit in installment payments, the accrued benefit payable will be redetermined on each subsequent valuation date until there is a complete distribution.

Note 14 — Stock Appreciation Reward Plan

The Company has established a stock appreciation reward program (the “Program”) that is offered to certain members of management. Under the Program, units are issued at the discretion of the Company. Each unit is valued at the intrinsic value, which is the difference between (i) $66.00 and (ii) the price of the Company’s stock on the reporting date. The units fully vest as of the determination date. The determination date is defined by the agreement as the first to occur of (a) December 31, 2026 or (b) a change in control has occurred. An obligation and compensation expense would be recorded when the occurrence of the determination date is deemed to be probable. Compensation expense of $456,914 has been recorded in 2019. As of June 30, 2020 and June 30, 2019, there were 6,000 stock appreciation reward units granted and assigned to certain members of management. As of June 30, 2020 and December 31, 2019, there were no stock appreciation rewards available to be granted.

Note 15 — Warrants

On May 1, 2018, a warrant to purchase 6,000 shares of the Incodema Inc.’s common stock was issued to the majority stockholder. The warrants have an exercise price of $79 per share. The obligations under the warrant are subordinated to certain bank obligations (see Note 7) as provided by a the substantiated agreement between the bank the majority stockholder. The obligations of the exercise period take effect at the 5-year period commencing on the earlier of the (i) sixth anniversary of the date of the warrants were granted or (ii) repayment in full of the note payable to the bank (see Note 7). The warrant term is the earlier of 11 years or contingent on repayment in full of the bank loan referenced above. As further discussed in Note 16 the warrants were cancelled in July 2020.

Note 16 — Subsequent Events

On July 23, 2020, the Company entered into a business combination event in which 100 percent of the ownership interest of Incodema, Inc. and NewChem, Inc. was sold to a new majority member for a total consideration of approximately $47,100,000. Prior to the transaction, Incodema, Inc. and NewChem, Inc. were converted to limited liability companies as part of a reorganization event.

June 30, 2020 and 2019

In conjunction with the sale, the Incodema ESOP received cash for all allocated and unallocated shares and was converted to a 401K plan, the Stock Appreciation Rights (SAR) were settled for an amount materially consistent with the liability recorded at June 30, 2020. In addition, the warrants described in Note 15 were cancelled.

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus pandemic. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the financial statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the balance sheet date, as no triggering events or changes in circumstances had occurred as of May 27, 2021; however, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows, and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

Board of Directors

Incodema, Inc. and NewChem, Inc.

We have audited the accompanying combined financial statements of Incodema, Inc. and New Chem Inc., which comprise the combined balance sheets as of December 31, 2019 and 2018, and the related combined statements of operations, stockholders’ equity, and cash flows for the years then ended, and the related notes to the financial statements.

Management’s responsibility for the financial statements

Management is responsible for the preparation and fair presentation of these combined financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of combined financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express an opinion on these combined financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the combined financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the combined financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the combined financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the combined financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the combined financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the combined financial statements referred to above present fairly, in all material respects, the financial position of Incodema, Inc. and NewChem, Inc. as of December 31, 2019 and 2018, and the results of their operations and their cash flows for the years then ended in accordance with accounting principles generally accepted in the United States of America.

Notes to Combined Financial Statements

December 31, 2019 and 2018

Note 1 — Nature of Business

Incodema, Inc. (Incodema) began operations in 2001 and is a prototype and short run sheet metal stamping provider which produces high quality items as sheet metal stampings, intricate metal formings, short run production stamping, laser cutting, and photo chemical machining (PCM).

NewChem, Inc. (NewChem) began operations after acquiring the assets of another entity on September 7, 2011. NewChem is a photochemical milling company located in Newark, NY. The process involves coating material specified with a light sensitive polymer, imaging with a photo tool using UV light, developing and then chemically etching.

Incodema and NewChem are collectively referred to as the “Company” throughout the combined financial statements.

Note 2 — Significant Accounting Policies

Basis of Presentation

The combined financial statements of the Company have been prepared on the basis of generally accepted accounting principles in the United States of America (U.S. GAAP). The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from those estimates.

Principles of Combination

The accompanying combined financial statements include the accounts of Incodema and NewChem, which are under common ownership. All material intercompany accounts and transactions have been eliminated in combination.

Cash Equivalents

For the purpose of the accompanying financial statements, the Company considers all highly liquid investments purchased with original maturities of three months or less to be cash equivalents. The carrying amount reported in the balance sheets for cash and cash equivalents approximates fair value due to the short-term nature of these investments.

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company places its temporary cash investments with high credit quality financial institutions and attempts to limit its amount of credit exposure to any one financial institution. However, at various times during the period, the Company’s cash balances exceeded the federally insured limits.

Accounts Receivable

The Company’s accounts receivable and unsecured customer obligations due under normal trade terms ordinarily requiring payment within (30) days from the invoice date. The company often has receivables paid net ninety (90) days for both automotive and aerospace industries. Accounts receivable are stated at the amount billed to the customer. The company does not accrue interest on accounts receivable. As of December 31, 2019 and December 31, 2018, management believed that all accounts receivable would be collected and as such did not record an allowance.

F-118

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

December 31, 2019 and 2018

Inventory

Inventory is stated at the lower of cost or net realizable value (NRV), with NRV based on selling price in the ordinary course of business, less costs of completion, disposal, and transportation. Cost are determined on a first-in, first-out (FIFO) method.

Property and Equipment

Property and equipment are recorded at cost. Both straight-line and accelerated methods are used for computing depreciation and amortization. Assets are depreciated over their estimated useful lives. The cost of leasehold improvements is depreciated over the lesser of the length of the related leases or the estimated useful lives of the assets. Costs of maintenance and repairs are charged to expense when incurred.

Goodwill

The recorded amounts of goodwill from prior business combinations are based on management’s best estimates of the fair values of assets acquired and liabilities assumed at the date of acquisition. Goodwill is not amortized, but rather is assessed at least on an annual basis for impairment.

No impairment charge was recognized during the years ended December 31, 2019 and 2018.

Employee Stock Ownership Plan

Compensation expense is recognized for the Employee Stock Ownership Plan (ESOP) equal to the average fair value of shares committed to be released for allocation to participant accounts. Any difference between the average fair value of shares committed to be released for allocation and the ESOP’s original acquisition cost is charged or credited to stockholders’ equity (additional paid-in capital). The cost of unallocated ESOP shares (shares not yet released for allocation) is reflected as a reduction of stockholders’ equity.

Revenue and Cost Recognition

The Company offers precision manufacturing and finishing services ranging from prototype through high-volume production, including internal sheet metal cutting and forming solutions, chemical etching, and medical device production for customers in the aerospace and defense, electronics, medical, automotive, and various other industries. The parts are shipped upon receipt of purchase orders and completion of the manufacturing process to customers who are located primarily in the United States.

During the year ended December 31, 2019 and 2018, the Company recognized revenue from contracts with customers of $15,135,876 and $12,694,259, respectively. All revenue was recognized at a point in time. The Company did not recognize any contract assets or liabilities.

Timing of Satisfaction

Contract terms do not include cancellation provisions that would result in an enforceable right to payment for performance completed to date, and, as a result, revenue is recognized at a point in time.

The Company satisfies its performance obligations as goods are produced or goods are delivered.

F-119

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

December 31, 2019 and 2018

Parts are typically shipped “FOB Shipping Point” based on the purchase order. For parts shipped as FOB Destination, ownership of goods in transit remains with the Company, and the Company bears the associated risks (e.g., loss, damage, or delay). In other cases, the customer will take delivery directly from the Company’s inventory (FOB Shipping Point), at which point ownership and the associated risk pass to the customer.

Contracts with customers usually contain only one performance obligation that is satisfied at a point in time. Contracts recognized at a point in time have no satisfied performance obligations that would result in contract assets other than trade accounts receivable.

Determining the Transaction Price

The transaction price of a contract is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer. Transaction prices do not include amounts collected on behalf of third parties (e.g., sales taxes).

To determine the transaction price of a contract, the Company considers its customary business practices and the terms of the contract. For the purpose of determining transaction prices, the Company assumes that the goods or services will be transferred to the customer as promised in accordance with existing contracts and that the contracts will not be canceled, renewed, or modified. All of the Company’s contracts with customers have fixed transaction prices that are denominated in U.S. dollars and payable in cash.

Significant Payment Terms

Payment for goods and services sold by the Company is typically due within 30 days after an invoice is sent to the customer.

Nature of Promises to Transfer

In most cases, goods that the Company contracts to transfer to customers are manufactured by the Company for sale. In no case does the Company act as an agent (i.e., the Company does not provide a service of arranging for another party to transfer goods or services to the customer).

Shipping and Handling

With respect to sales of goods shipped FOB Shipping Point, the Company performs shipping and handling activities after its customers obtain control of the goods in some cases. The Company’s policy is to account for shipping and handling as activities to fulfill its promise to transfer the good (i.e., shipping and handling activities are expensed). With respect to sales of parts that are shipped “FOB Shipping Point,” the Company recognizes revenue before it performs shipping and handling activities, and the costs are accrued at that time.

Income Taxes

Pursuant to provisions of the Internal Revenue Code, the Company has elected to be taxed as an S corporation. Generally, the income of an S corporation is not subject to federal income tax at the corporate level, but rather the stockholders are required to include a pro-rata share of the corporation’s taxable income or loss in their personal income tax returns, irrespective of whether dividends have been paid. Accordingly, no provision for federal income taxes has been made in the accompanying financial statements.

Incodema, Inc. and NewChem, Inc.

Notes to Combined Financial Statements

December 31, 2019 and 2018

Use of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Credit Risk, Major Customers, and Suppliers

In 2019 and 2018, sales to one customer comprised of 22 and 17 percent of total Company revenue, respectively. Management notes that sales to specific customers tend to be cyclical and customer concentrations frequently shift. In 2019 and 2018, outstanding receivables to one customer comprised of 17 and 12 percent, respectively.

In 2019 and 2018, purchases from a supplier comprised of 6 and 5 percent of total Company revenue, respectively. Management notes that purchases from specific vendors could cause the Company to experience delays and reduce efficiencies in operations if supplier were to cease supplying services to the Company. In 2019 and 2018, outstanding payables to one customer comprised of 13 and 12 percent, respectively.

Upcoming Accounting Pronouncements

The Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases, which will supersede the current lease requirements in ASC 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The reporting of lease-related expenses in the statements of operations and cash flows will be generally consistent with the current guidance. The new lease guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a modified retrospective transition method to either the beginning of the earliest period presented or the beginning of the year of adoption. The Company is still evaluating which method it will apply. The new lease standard is expected to have a significant effect on the Company’s financial statements as a result of the Company’s operating leases, as disclosed in Note 11, that will be reported on the balance sheet at adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to-use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

In June 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2016-13, Financial Instruments — Credit Losses: Measurement of Credit Losses on Financial Instruments. The ASU includes changes to the accounting and measurement of financial assets including the Company’s accounts receivable and held-to-maturity debt securities by requiring the Company to recognize an allowance for all expected losses over the life of the financial asset at origination. This is different from the current practice where an allowance is not recognized until the losses are considered probable. The ASU also changes the way credit losses are recognized for available-for-sale debt securities. Credit losses are recognized through the recording of an allowance rather than as a write-down of the carrying value. The new guidance will be effective for the Company’s year ending December 31, 2021. Upon adoption, the ASU will be applied using a modified retrospective transition method to the beginning of the earliest period presented. The Company does not believe the adoption of the new standard will have a significant effect on the combined financial statements.

Subsequent Events

The financial statements and related disclosures include evaluation of events up through and including July 28, 2021, which is the date the financial statements were available to be issued.

Note 3 — Adoption of New Accounting Standard

As of January 1, 2019, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. The ASU is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted the new standard using the modified retrospective method to all contracts effective January 1, 2019 and is using a portfolio approach to group contracts with similar characteristics. Modified retrospective adoption requires entities to apply the standard retrospectively to the most current period presented in the financial statements, requiring the cumulative effect of the retrospective application as an adjustment to the opening balance of retained earnings at the date of initial application. Prior periods have not been adjusted. No cumulative-effect adjustment in net assets was recorded as the adoption of ASU did not significantly impact the Company’s reported historical revenue. There was not a significant impact on the amount of revenue recognized from contracts with customers for the year ended December 31, 2019 and 2018 as a result of adopting the new guidance.

Note 12 — Retirement Plans

The Company adopted a 401(K) safe harbor plan for employees in October 2002. Employees are eligible to participate after successful completion of their ninety-day probationary period, if applicable, attaining 21 years of age and a minimum of 1,000 hours of service. Vesting is immediate. The Company matches 100 percent of each dollar of employee contribution up to 3 percent of annual compensation. For the fourth and fifth percent an employee defers, the Company matches 50 percent. The maximum match per year is 4 percent of the employees’ W-2 compensation. Contribution expense for the years ended December 31, 2019 and 2018 was $115,212 and $101,705, respectively.

Note 13 — Employee Stock Ownership Plan (ESOP)

Incodema sponsors a leveraged employee stock ownership plan (the “ESOP” or the “Plan”) that was established January 1, 2017. Employees are eligible to participate in the plan upon attainment of age 21 and completion of one-thousand (1,000) hours of service in an eligibility computation period. All Employees employed by the Company on January 1, 2017, were immediately eligible to participate in the Plan. The purpose of the Plan is to provide retirement benefits for eligible employees. The Plan is intended to qualify as an employee stock ownership plan under Sections 401(a) and 4975(3)(7) of the Code as well as Section 407(d)(6) of ERISA.

The ESOP originally purchased 43,011 shares of Incodema comment stock using proceeds of a $4,000,000 loan issued from Incodema. This ESOP loan bears interest at 3.04 percent per annum, and matures on April 30, 2038. The loan payments are funded through contributions to the Plan made by Incodema.

In accordance with applicable accounting standards, the loan between Incodema and the ESOP is not presented as an asset within the combined balance sheet but rather a contra equity account described as “unearned ESOP shares.” The shares held by the ESOP are allocated to participant accounts, as the repayments are made by the Plan. Shares are released based on debt service paid and allocated to active participants based on a formula of the participants’ pro rata shares of eligible compensation. The unearned ESOP shares account reported as contra equity is reduced as compensation expense is recognized under the Plan. For the years ended December 31, 2019 and December 31, 2018, the Company accrued and made contributions to the ESOP of $587,995 and $267,240, respectively. The Company reported related compensation expense of $1,754,544 and $488,116 for the years ended December 31, 2019 and December 31, 2018, respectively. The amounts were paid by the end of 2019 and 2018, respectively and contribution amount was determined based on eligible employees’ compensation.

Upon retirement, the value of the participant’s accrued benefit payable as recalculated as of the most recent valuation date prior to the date of distribution. If the participant chooses to receive their benefit in installment payments, the accrued benefit payable will be redetermined on each subsequent valuation date until there is a complete distribution.

The obligations under the warrant are subordinated to certain bank obligations (see Note 8) as provided by a the subordinated agreement between the bank the majority stockholder. The obligations of the exercise period take effect at the 5-year period commencing on the earlier of the (i) sixth anniversary of the date of the warrants were granted or (ii) repayment in full of the note payable to the bank (see Note 8).

Note 16 — Subsequent Events

On July 26, 2020, the Company entered into a business combination event in which 100 percent of ownership interest of Incodema, Inc. and NewChem, Inc. was sold to a new majority member for a total consideration of approximately $47,100,000. Prior to the transaction, Incodema, Inc. and NewChem, Inc. were converted to limited liability companies as part of a reorganization event.

In addition, the warrants described in Note 15 were cancelled.

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus pandemic. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the financial statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the balance sheet date, as no triggering events or changes in circumstances had occurred as of May 27, 2021; however, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows, and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

Notes to Financial Statements

September 30, 2020 and December 31, 2019

Note 1 — Nature of Business

Majestic Metals, LLC a Colorado Limited Liability Company (the “Company”), is a subcontract manufacturer of sheet metal components and assemblies. The Company provides a wide range of manufacturing processes including final finishing and assembly to a diverse group of industries including medical electronics, computer electronics, lighting, and industrial applications.

The financial statements herein include the period from January 1, 2020 to September 30, 2020 (hereinafter referred to as “the period ended September 30, 2020”) and the year ending December 31, 2019.

Note 2 — Significant Accounting Policies

Basis of Presentation

The financial statements of the Company have been prepared on the basis of accounting principles generally accepted in the United States of America (U.S. GAAP). The preparation of financial statements in conformity with generally accepted accounting principles in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus pandemic. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the financial statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the balance sheet date, as no triggering events or changes in circumstances had occurred as of September 30, 2020; however, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows, and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

Accounts Receivable

The Company grants credit to its customers in the ordinary course of business. The allowance for doubtful accounts is based on management’s assessment of the collectability of specific customer accounts and includes consideration of the credit worthiness and financial condition of those specific customers. The Company records an allowance to reduce the specific receivables to the amount that is reasonably believed to be collectible. The Company also records an allowance for all other trade receivables based on multiple factors including historical experience with bad debts, the general economic environment, the financial condition of the Company’s distributions channels, and the aging of such receivables. Amounts are considered past due based upon contractual terms. Accounts are written off when they are deemed uncollectible based on management’s judgment. The Company does not charge interest on past due receivables. The allowance for doubtful accounts was $50,000 as of September 30, 2020 and December 31, 2019. There was no bad debt expense for the period ended September 30, 2020 and year ended December 31, 2019.

Concentration Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash. The Company places its cash with high credit quality financial institutions and attempts to

F-133

Majestic Metals, LLC

Notes to Financial Statements

September 30, 2020 and December 31, 2019

limit its amount of credit exposure to any one financial institution. However, at various times during the year, the Company’s cash balances exceeded the federally insured limits. The FDIC (Federal Deposit Insurance Corporation) insures cash deposits up to $250,000.

The majority of the Company’s sales and accounts receivable are with local and regional manufacturing customers. Sales to two major customers represent 32% and 33% of total sales for the period ended September 30, 2020 and year ended December 31, 2019, respectively. Accounts receivable from these major customers represents 31% and 34% of total accounts receivable at September 30, 2020 and December 31, 2019, respectfully.

Inventory

Inventory consists of purchased parts and work-in-process, and are valued at the lower of cost or net realizable value. Costs are determined on the first-in, first-out (FIFO) method. The Company evaluates inventory for slow-moving and obsolete items and records an allowance as necessary. Based on management’s analysis, no allowance for slow-moving and obsolete inventory was deemed necessary at September 30, 2020 and December 31, 2019.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is computed using the straight-line method for computer equipment and software, office furniture and equipment applied to individual property items based on estimated useful lives. Costs of maintenance and repairs are charged to expense when incurred. The cost of leasehold improvements is depreciated over the lesser of the length of the related leases or the estimated useful lives of the assets.

Revenue Recognition

The Company offers precision manufacturing and finishing services ranging from prototype through high-volume production, including internal sheet metal cutting and forming solutions, chemical etching, and medical device production for customers in the aerospace and defense, electronics, medical, automotive, and various other industries. The parts are shipped upon receipt of purchase orders and completion of the manufacturing process to customers who are located primarily in the United States.

During the period ended September 30, 2020 and the year ended December 31, 2019, the Company recognized revenue from contracts with customers of $17,233,964 and $25,733,700. The Company did not recognize any contract assets or liabilities.

Timing of Satisfaction

Contract terms do not include cancellation provisions that would result in an enforceable right to payment for performance completed to date, and, as a result, revenue is recognized at a point in time.

The Company satisfies its performance obligations once goods are produced and shipped.

Good associated with contracts are primarily shipped “FOB Shipping Point” based on the contractual terms. For contract terms shipped FOB Shipping Point, the customer will take title directly from the Company upon shipment, at which point ownership and the associated risk pass to the customer. For a small portion of contracts, contract terms are FOB Destination, where ownership of the goods in transit remains with the Company and the Company bears the associated risks (e.g., loss, damage, or delay) until it is delivered to the customer location.

Notes to Financial Statements

September 30, 2020 and December 31, 2019

Contracts with customers contain only one performance obligation that is satisfied at a point in time based on contractual terms. Contracts recognized at a point in time have no satisfied performance obligations that would result in contract assets or liabilities.

Determining the Transaction Price

The transaction price of a contract is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer. The Company does not collect sales tax on behalf of third parties, as the Company’s customer base is largely tax exempt. For a small portion of contracts where sales tax is applicable, the Company will accrue the related tax at the point the contract is completed.

To determine the transaction price of a contract, the Company considers its customary business practices and the terms of the contract. For the purpose of determining transaction prices, the Company assumes that the goods or services will be transferred to the customer as promised in accordance with existing contracts and that the contracts will not be canceled, renewed, or modified. All the Company’s contracts with customers have fixed transaction prices that are denominated in U.S. dollars and payable in cash.

Significant Payment Terms

Payment for goods and services sold by the Company is typically due within 30 days after an invoice is sent to the customer.

Nature of Promises to Transfer

In all cases, goods that the Company contracts to transfer to customers are manufactured by the Company for sale. In no case does the Company act as an agent (i.e., the Company does not provide a service of arranging for another party to transfer goods or services to the customer).

Shipping and Handling

With respect to contracts with shipped FOB Shipping Point terms, the Company may perform shipping and handling activities after its customers obtain control of the goods. The Company’s policy is to account for shipping and handling as activities to fulfill its promise to transfer the good (i.e., shipping and handling activities are expensed) and included in cost of sales.

Warranties

The Company offers a 30-day general warranty and no extended warranty. The Company will either scrap the returned material and issue customer credits for the original sales amount or perform repairs over defective products. Repairs and scrap costs are expensed as products are received. The Company does not have a return policy.

Income Taxes

The Company is treated as a partnership for federal income tax purposes. Consequently, federal income taxes are not payable or provided for by the Company. Members are taxed individually on their pro-rata ownership share of the Company’s earnings. The Company’s net income or loss is allocated among the members in accordance with the Company’s operating agreement.

Notes to Financial Statements

September 30, 2020 and December 31, 2019

No federal income tax provision has been included in the financial statements since income or loss of the Company is required to be reported by the respective members on their income tax returns. The Company is subject to certain state and local income and franchise taxes, which are included in the financial statements.

New Accounting Pronouncements

The Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2016-02, Leases, which will supersede the current lease requirements in Accounting Standards Codification (ASC) 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The reporting of lease-related expenses in the statements of operations and cash flows will be generally consistent with the current guidance. On June 3, 2020, the FASB issued ASU 2020-05, which amended the effective date ASU 2016-02 to give immediate relief to certain entities as a result of the widespread adverse economic effects and business disruptions caused by the coronavirus disease 2019 (COVID-19) pandemic. The new lease guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a current period adjustment method to the beginning of the year of adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to-use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant, as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

Under the terms of this program, the loan may be fully or partially forgiven if the loan proceeds are spent on qualifying expenses and if staffing level and salary maintenance requirements were met. The Company may use the funds on qualifying expenses over a covered period of up to 24 weeks. At the conclusion of the covered period, any balance that is not forgiven by the SBA would be repaid within two years from issuance date with interest accruing at a rate of 1 percent, with monthly payments of principal and interest beginning ten months after the conclusion of the covered period. Based on the loan amount, irrespective of any potential forgiveness that may be granted in the future, monthly principal payments would be approximately $115,000 during the repayment period.

Management’s responsibility for the financial statements

Management is responsible for the preparation and fair presentation of these financial statements in accordance with accounting principles generally accepted in the United States of America; this includes the design, implementation, and maintenance of internal control relevant to the preparation and fair presentation of financial statements that are free from material misstatement, whether due to fraud or error.

Auditor’s responsibility

Our responsibility is to express an opinion on these financial statements based on our audit. We conducted our audit in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free from material misstatement.

An audit involves performing procedures to obtain audit evidence about the amounts and disclosures in the financial statements. The procedures selected depend on the auditor’s judgment, including the assessment of the risks of material misstatement of the financial statements, whether due to fraud or error. In making those risk assessments, the auditor considers internal control relevant to the entity’s preparation and fair presentation of the financial statements in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the entity’s internal control. Accordingly, we express no such opinion. An audit also includes evaluating the appropriateness of accounting policies used and the reasonableness of significant accounting estimates made by management, as well as evaluating the overall presentation of the financial statements.

We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our audit opinion.

Opinion

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of Dahlquist Machine, Inc. as of September 30, 2020, and the results of its operations and its cash flows for the nine-month period ended September 30, 2020 in accordance with accounting principles generally accepted in the United States of America.

Notes to Financial Statements

September 30, 2020

Note 1 — Nature of Business

Dahlquist Machine, Inc. (the “Company”) a Minnesota corporation, is a precision machining company located in Ham Lake, Minnesota. The Company was founded in 1969 and specializes in high-speed machining of aluminum, light metals, and plastic parts for consumers across a wide variety of industries.

Note 2 — Significant Accounting Policies

Basis of Presentation

The financial statements of the Company have been prepared on the basis of accounting principles generally accepted in the United States of America (GAAP). The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Actual results could differ from those estimates.

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of a respiratory disease caused by a new coronavirus pandemic. First identified in late 2019 and now known as COVID-19, the outbreak has impacted millions of individuals worldwide. As of the date of issuance of the financial statements, the Company’s operations have not been significantly impacted, but the Company continues to monitor the situation. No impairments were recorded as of the balance sheet date, as no triggering events or changes in circumstances had occurred as of September 30, 2020. However, due to significant uncertainty surrounding the situation, management’s judgment regarding this could change in the future. In addition, while the Company’s results of operations, cash flows, and financial condition were not significantly impacted, the extent of any future impact cannot be reasonably estimated at this time.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all investments with an original maturity of three months or less when purchased to be cash equivalents.

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents. The Company places its temporary cash investments with high credit quality financial institutions and attempts to limit its amount of credit exposure to any one financial institution. However, at various times during the period, the Company’s cash balances exceeded the federally insured limits. As of September 30, 2020, the Company had $5,390,918 on deposit with financial institutions in excess of the federally insured limits.

Accounts Receivable

Accounts receivable are stated at invoice cost. Based on management’s review of outstanding receivable balances and historical collection information, management’s best estimate is that all balances will be collected. Accordingly, the Company has not established an allowance for doubtful accounts.

F-145

Dahlquist Machine, Inc.

Notes to Financial Statements

September 30, 2020

Credit Risk and Major Customers

The majority of the Company’s sales and accounts receivable are with local and regional manufacturing customers. The Company grants credit to its customers during the normal course of business. The Company performs ongoing credit evaluations of its customers’ financial condition and generally does not require collateral from its customers. Sales to two major customers represent 42% of total sales at September 30, 2020. Accounts receivable from these major customers represents 43% of total accounts receivable at September 30, 2020.

Inventory

Inventory consists of primarily finished goods from purchased parts and work-in-process, which are valued at the lower of cost or net realizable value, as determined by the first-in, first-out method. The Company evaluates inventory for slow-moving and obsolete items and records an allowance as necessary. Based on management’s analysis, an allowance for slow-moving and obsolete inventory was recorded in the amount of $226,657 as of September 30, 2020.

Property and Equipment

Property and equipment are recorded at cost. Depreciation is computed using the straight line or accelerated method based on estimated useful lives. Costs of maintenance and repairs are charged to expense when incurred. The cost of leasehold improvements is depreciated over the lesser of the length of the related leases or the estimated useful lives of the assets.

Property and equipment are reviewed for potential impairment whenever events or circumstances indicate that carrying amounts may not be recoverable.

Revenue and Cost Recognition

The Company is a precision machining company that specializes in short to medium-run quantities for high precision parts, focusing on machining aluminum, light metals, and plastic parts. The Company sells primarily to customers in the aerospace and defense, electronics, medical, and various other industries who are located primarily in the United States.

During the nine-month period ended September 30, 2020 the Company recognized revenue from contracts with customers of $6,043,145. The Company did not recognize any contract assets or liabilities. Accounts receivable at September 30, 2020 and January 1, 2020 was $1,204,535 and $861,959, respectively.

Timing of Satisfaction

Contract terms do not include cancellation provisions that would result in an enforceable right to payment for performance completed to date, and, as a result, revenue is recognized at a point in time.

Contracts with customers usually contain only one performance obligation that is satisfied at a point in time. The timing of satisfaction is dictated by the contractual shipping terms agreed upon by both parties.

Parts are typically shipped “FOB Shipping Point” based on the purchase order. The Company satisfies its performance obligations as goods are prepared for shipment and isolated from inventory. Upon shipment, ownership of goods and the associated risk pass to the customer. For a small portion of contracts, shipping terms are “FOB Destination”, whereas the Company retains ownership of goods in transit and thus bears the associated risks (e.g., loss, damage, or delay) until the goods are delivered to the customer location.

F-146

Dahlquist Machine, Inc.

Notes to Financial Statements

September 30, 2020

Contracts recognized at a point in time have no satisfied performance obligations that would result in contract assets other than trade accounts receivable.

Determining the Transaction Price

The transaction price of a contract is the amount of consideration to which the Company expects to be entitled in exchange for transferring promised goods or services to a customer. Transaction prices do not include amounts collected on behalf of third parties (e.g., sales taxes).

To determine the transaction price of a contract, the Company considers its customary business practices and the terms of the contract. For the purpose of determining transaction prices, the Company assumes that the goods or services will be transferred to the customer as promised in accordance with existing contracts and that the contracts will not be cancelled, renewed, or modified. All of the Company’s contracts with customers have fixed transaction prices that are denominated in U.S. dollars and payable in cash.

Significant Payment Terms

Payment for goods and services sold by the Company is typically due within 30 days after an invoice is sent to the customer.

Nature of Promises to Transfer

In most cases, goods that the Company contracts to transfer to customers are manufactured by the Company for sale. In no case does the Company act as an agent (i.e., the Company does not provide a service of arranging for another party to transfer goods or services to the customer).

Shipping and Handling Costs

Shipping and handling activities are carried out either by the customer or arranged by the Company. The Company considers all shipping and handling costs as costs to fulfill the contract.

Income Taxes

Pursuant to provisions of the Internal Revenue Code, the Company has elected to be taxed as an S corporation. Generally, the income of an S corporation is not subject to federal income tax at the corporate level, but rather the stockholders are required to include a pro-rata share of the corporation’s taxable income or loss in their personal income tax returns, irrespective of whether dividends have been paid. Accordingly, no provision for federal income taxes has been made in the accompanying financial statements.

Upcoming Accounting Pronouncements

The Financial Accounting Standards Board (FASB) issued ASU 2016-02, Leases, which will supersede the current lease requirements in Accounting Standards Codification (ASC) 840. The ASU requires lessees to recognize a right-to-use asset and related lease liability for all leases, with a limited exception for short-term leases. Leases will be classified as either finance or operating, with the classification affecting the pattern of expense recognition in the statement of operations. Currently, leases are classified as either capital or operating, with only capital leases recognized on the balance sheet. The reporting of lease-related expenses in the statements of operations and cash flows will be generally consistent with the current guidance. The new lease

guidance will be effective for the Company’s year ending December 31, 2022 and will be applied using a modified retrospective transition method to either the beginning of the earliest period presented or the beginning of the year of adoption. Upon adoption, the Company will recognize a lease liability and corresponding right-to-use asset based on the present value of the minimum lease payments. The effects on the results of operations are not expected to be significant, as recognition and measurement of expenses and cash flows for leases will be substantially the same under the new standard.

Note 5 — Paycheck Protection Program Loan

During the nine-month period ended September 30, 2020, the Company received a Paycheck Protection Program (PPP) loan in the amount of $518,100. The PPP loan program was created under the Coronavirus Aid, Relief, and Economic Security (CARES) Act and is administered by the Small Business Administration (SBA). Under the terms of this program, the loan may be fully or partially forgiven if the loan proceeds are spent on qualifying expenses and if staffing level and salary maintenance requirements were met. The Company may use the funds on qualifying expenses over a covered period of up to 24 weeks. At the conclusion of the covered period, any balance that is not forgiven by the SBA would be repaid within two years from issuance date with interest accruing at a rate of 1 percent, with monthly payments of principal and interest beginning ten months after the conclusion of the covered period. Based on the loan amount, irrespective of any potential forgiveness that may be granted in the future, monthly principal payments would be approximately $29,200 during the repayment period.

Fathom Digital Manufacturing Corporation, a corporation organized and existing under the laws of the State of Delaware, does hereby certify as follows:

ARTICLE ONE

The name of the corporation is Fathom Digital Manufacturing Corporation (the “Corporation”).

ARTICLE TWO

The address of the Corporation’s registered office in the State of Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle, Delaware, 19801. The name of its registered agent at such address is The Corporation Trust Company.

ARTICLE THREE

The nature and purpose of the business of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”). The Corporation is being incorporated in connection with the domestication of Altimar Acquisition Corp. II, a Cayman Islands exempted company (“Altimar Cayman”), as a Delaware corporation (the “Domestication”), and this Certificate of Incorporation (as hereinafter defined) and the Certificate of Corporate Domestication of Altimar Cayman are being filed simultaneously with the Secretary of State of the State of Delaware.

ARTICLE FOUR

Section 1. Authorized Shares. The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is 500,000,000 shares, consisting of the following:

1. 10,000,000 shares of Preferred Stock, par value $0.0001 per share (the “Preferred Stock”);

2. 300,000,000 shares of Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock”);

3. 180,000,000 shares of Class B Common Stock, par value $0.0001 per share (the “Class B Common Stock”); and

4. 10,000,000 shares of Class C Common Stock, par value $0.0001 per share (the “Class C Common Stock” and, together with the Class A Common Stock and Class B Common Stock, the “Common Stock”).

Upon the effectiveness of the Domestication and this Certificate of Incorporation (A) each Class A ordinary share, par value $0.0001 per share (a “Class A Cayman Share”), of Altimar Cayman that is outstanding immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation will, for all purposes, be deemed to be one issued and outstanding, fully paid and non-assessable share of Class A Common Stock of the Corporation, without any action required on the part of the Corporation or the holders thereof,

A-1

(B) each Class B ordinary share, par value $0.0001 per share (a “Class B Cayman Share”), of Altimar Cayman that is outstanding immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation will, for all purposes, be deemed to be one issued and outstanding, fully paid and non-assessable share of Class C Common Stock of the Corporation, without any action required on the part of the Corporation or the holders thereof, and (C) any stock certificate that, immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation, represented Class A Cayman Shares or Class B Cayman Shares will, from and after the effectiveness of the Domestication and this Certificate of Incorporation, automatically and without the necessity of presenting the same for exchange, represent an identical number of shares of Class A Common Stock or Class C Common Stock (respectively) of the Corporation, as applicable. Notwithstanding anything to the contrary herein, following the filing and effectiveness of this Certificate of Incorporation with the Secretary of State of the State of Delaware, the Corporation shall not issue additional shares of Class C Common Stock.

The Preferred Stock and the Common Stock shall have the designations, rights, powers and preferences and the qualifications, restrictions and limitations thereof, if any, set forth below. The number of authorized shares of Class A Common Stock, Class B Common Stock, Class C Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the approval of the Board of Directors of the Corporation (the “Board of Directors”) and by the affirmative vote of the holders of a majority in voting power of the then-outstanding shares of capital stock of the Corporation entitled to vote generally in an election of directors, and no vote of the holders of any of Class A Common Stock, Class B Common Stock, Class C Common Stock or Preferred Stock voting separately as a class shall be required therefor, regardless of the provisions of Section 242(b)(2) of the DGCL (or any successor provisions thereto). No stockholder shall, by reason of the holding of shares of any class or series of capital stock of the Corporation, have any preemptive or preferential right to acquire or subscribe for any shares or securities of any class or series, whether now or hereafter authorized, which may at any time be issued, sold or offered for sale by the Corporation, unless specifically provided for in a Preferred Stock Designation (as hereinafter defined). The Corporation has the authority to create and issue rights, warrants and options entitling the holders thereof to acquire from the Corporation any shares of its capital stock of any class or classes, with such rights, warrants and options to be evidenced by or in instrument(s) approved by the Board of Directors. The Board of Directors is empowered to set the exercise price, duration, times for exercise and other terms and conditions of such rights, warrants or options. Notwithstanding the foregoing, the consideration to be received for any shares of capital stock issuable upon exercise thereof may not be less than the par value thereof. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of capital stock a number of shares of the class of capital stock issuable pursuant to any such rights, warrants and options outstanding from time to time.

Section 2. Preferred Stock. The Board of Directors is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions for the issuance of shares of Preferred Stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series, and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, restrictions or limitations thereof, as are stated and expressed herein and in the resolution or resolutions providing for the issue of such class or series adopted by the Board of Directors and included in a certificate or certificates of designation (each, a “Preferred Stock Designation”). The powers (including voting powers), preferences, and relative, participating, optional and other special rights of each series of Preferred Stock and the qualifications, restrictions or limitations thereof, if any, may differ from those of any and all other series at any time outstanding. Except as otherwise required by law, holders of a series of Preferred Stock, as such, shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Certificate of Incorporation (including any Preferred Stock Designation relating to such series).

Section 3. Common Stock.

(a) Except as otherwise provided by the DGCL or this Certificate of Incorporation (as it may be amended, the “Certificate of Incorporation”), and subject to the rights of holders of any series of Preferred Stock, all of the

A-2

voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any Preferred Stock Designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate of Incorporation (including any Preferred Stock Designation relating to any series of Preferred Stock) or pursuant to the DGCL.

(b) Except as otherwise required by law or expressly provided in this Certificate of Incorporation, each share of Common Stock shall have the same powers, rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

(c) Subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and this Certificate of Incorporation, the holders of shares of Class A Common Stock and, solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction (as hereinafter defined), holders of Class C Common Stock, in each case shall be entitled to receive ratably in proportion to the number of shares of Class A Common Stock and Class C Common Stock (as applicable) held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the Board of Directors at any time and from time to time out of any funds of the Corporation legally available therefor. There will be no disparate consideration or treatment with respect to dividends and distributions, if any, declared or payable in respect of each share of the Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction), on the one hand, and a Class A Unit (as defined in the LLC Agreement (as hereinafter defined)), on the other hand. Dividends and other distributions shall not be declared or paid on the Class B Common Stock unless (i) the dividend consists of shares of Class B Common Stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B Common Stock paid proportionally with respect to each outstanding share of Class B Common Stock and (ii) a dividend consisting of shares of Class A Common Stock, Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A Common Stock (to the extent a similar or contemporaneous dividend or distribution is not paid on the Class A Units) or Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) on equivalent terms is simultaneously paid to the holders of Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction). If dividends are declared on the Class A Common Stock, the Class B Common Stock or the Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) that are payable in shares of Common Stock, or securities convertible into, or exercisable or exchangeable for Common Stock, the dividends payable to the holders of Class A Common Stock shall be paid only in shares of Class A Common Stock (or securities convertible into, or exercisable or exchangeable for Class A Common Stock), the dividends payable to the holders of Class B Common Stock shall be paid only in shares of Class B Common Stock (or securities convertible into, or exercisable or exchangeable for Class B Common Stock), the dividends payable to the holders of Class C Common Stock shall be paid only in shares of Class C Common Stock (or securities convertible into, or exercisable or exchangeable for Class C Common Stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock, Class B Common Stock and Class C Common Stock, respectively (or securities convertible into, or exercisable or exchangeable for the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock, Class B Common Stock and Class C Common Stock, respectively). For purposes of this Certificate of Incorporation, “BCA Transaction” means the business combination transactions contemplated by that certain Business Combination Agreement, dated as of July 15, 2021, by and among Altimar Cayman, Fathom Holdco, LLC and other Persons party thereto, as the same may be amended, restated, supplemented or waived from time to time (the “BCA”).

A-3

(d) In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after distribution in full of the preferential amounts, if any, to be distributed to the holders of shares of Preferred Stock or any series thereof, the holders of shares of Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) shall be entitled to receive all of the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Class A Common Stock and Class C Common Stock (as applicable) held by them. The holders of shares of Class B Common Stock, as such, shall not be entitled to receive any assets of the Corporation in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Corporation. A dissolution, liquidation or winding-up of the Corporation, as such terms are used in this paragraph (d), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other corporation or corporations or other entity or a sale, lease, exchange or conveyance of all or a part of the assets of the Corporation; provided, that notwithstanding anything to the contrary herein, in the event of any such merger, sale, lease, exchange or conveyance, or any other similar transaction or recapitalization, the holders of shares of Class B Common Stock shall not be entitled to any consideration in connection therewith other than the right to receive securities with equivalent terms and conditions as the Class B Common Stock, and the consideration payable in respect of a share of Class A Common Stock shall equal the consideration payable in respect of a Class A Unit.

(e) Shares of Class B Common Stock shall be redeemable for shares of Class A Common Stock on the terms and subject to the conditions set forth in the Second Amended and Restated Limited Liability Company Agreement of Fathom Holdco, LLC, dated as of [                    ], 2021, as it may be amended from time to time in accordance with its terms (the “LLC Agreement”). The Corporation will at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of issuance upon redemption of the outstanding shares of Class B Common Stock for Class A Common Stock pursuant to the LLC Agreement, such number of shares of Class A Common Stock that shall be issuable upon any such redemption pursuant to the LLC Agreement; provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its or its affiliates’ obligations in respect of any such redemption of shares of Class B Common Stock pursuant to the LLC Agreement by delivering (either directly or indirectly through an affiliate) to the holder of shares of Class B Common Stock upon such redemption, in lieu of newly issued shares of Class A Common Stock, cash in the amount permitted by and provided in the LLC Agreement or shares of Class A Common Stock which are held in the treasury of the Corporation. All shares of Class A Common Stock that may be issued upon any such redemption shall, upon issuance in accordance with the LLC Agreement, be validly issued, fully paid and non-assessable. All shares of Class B Common Stock redeemed shall not be disposed of out of treasury or otherwise reissued and shall be cancelled.

(f) Conversion of Class C Common Stock.

(i) Shares of Class C Common Stock shall automatically convert into shares of Class A Common Stock on a one-for-one basis (the “Initial Conversion Ratio”): (A) at any time and from time to time at the option of the holder thereof; or (B) automatically and without further action by the Corporation or the holder thereof on the day of the closing of a Business Combination, which for the avoidance of doubt will be the closing of the BCA Transaction.

(ii) Notwithstanding the Initial Conversion Ratio, in the case that additional shares of Class A Common Stock or any other Equity-linked Securities (as hereinafter defined), are issued or deemed issued in excess of the amounts offered in the IPO and related to the closing of a Business Combination, all outstanding shares of Class C Common Stock shall automatically convert into shares of Class A Common Stock at the time of the closing of a Business Combination at such ratio (unless the holders of a majority of the outstanding shares of Class C Common Stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) that results in the number of shares of Class A Common Stock issuable upon conversion of all outstanding shares of Class C Common Stock be equal to, in the aggregate, 20% of the sum of all shares of Class A Common Stock and Class C Common Stock outstanding upon completion of the IPO plus all shares of

A-4

Class A Common Stock and Equity-linked Securities issued or deemed issued in connection with a Business Combination, excluding any shares or Equity-linked Securities issued, or to be issued, to any seller in an initial Business Combination.

(iii) Notwithstanding anything to the contrary contained herein, the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional shares of Class A Common Stock or Equity-linked Securities by the written consent or agreement of holders of a majority of the outstanding shares of Class C Common Stock consenting or agreeing separately as a separate class.

(iv) The foregoing conversion ratio shall also be adjusted to account for any subdivision (by share split, subdivision, exchange, capitalization, rights issue, reclassification, recapitalization or otherwise) or combination (by reverse share split, share consolidation, exchange, reclassification, recapitalization or otherwise) or similar reclassification or recapitalizations of the outstanding shares of Class A Common Stock into a greater or lesser number of shares occurring after the Effective Date without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalization of the outstanding shares of Class C Common Stock.

(v) Each share of Class C Common Stock shall convert into its pro rata number of shares of Class A Common Stock pursuant to this Section 3(f). The pro rata share for each holder of shares of Class C Common Stock will be determined as follows: each share of Class C Common Stock shall convert into such number of shares of Class A Common Stock as is equal to the product of one multiplied by a fraction, the numerator of which shall be the total number of shares of Class C Common Stock into which all of the outstanding shares of Class C Common Stock in issue shall be converted pursuant to this Section 3(f) and the denominator of which shall be the total number of outstanding shares of Class C Common Stock at the time of conversion.

(vi) Notwithstanding anything to the contrary in this Section 3(f), in no event may any share of Class C Common Stock convert into shares of Class A Common Stock at a ratio that is less than one-for-one

(vii) As used in this Section 3(f):

(A) “converted”, “conversion” or “exchange” shall have its ordinary meaning under Delaware law, and thereby shall have the same effect as a compulsory redemption without notice of shares of Class C Common Stock of any stockholder and, on behalf of such stockholders, automatic application of such redemption proceeds in paying for such new shares of Class A Common Stock into which the shares of Class C Common Stock have been converted or exchanged at a price per share of Class C Common Stock necessary to give effect to a conversion or exchange calculated on the basis that the shares of Class A Common Stock to be issued as part of the conversion or exchange will be issued at par. The shares of Class A Common Stock to be issued on an exchange or conversion shall be registered in the name of such stockholder or in such name as the stockholder may direct;

(B) “Equity-linked Securities” means any debt or equity securities that are convertible, exercisable or exchangeable for shares of Class A Common Stock issued in a financing transaction in connection with a Business Combination, including, but not limited to, a private placement of equity or debt; and

(C) “IPO” means the initial public offering of Altimar Cayman.

(viii) Shares of Class C Common Stock converted into shares of Class A Common Stock pursuant to Section 3(f) shall be cancelled by the Corporation and may not be reissued. At any time after consummation of a Business Combination, when there are no longer any shares of Class C Common Stock outstanding, the Corporation shall take all necessary action to retire and eliminate the Class C Common Stock, and shall amend this Certificate of Incorporation to eliminate references thereto.

(xi) Nothing in Section 3(f) of this Certificate of Incorporation shall limit or amend any obligation or agreement of any party to the Sponsor Agreement. To the extent of any conflict or inconsistency between the terms and

A-5

provisions of the Sponsor Agreement and the terms and provisions of this Certificate of Incorporation, including (without limitation) Section 3(f) hereof, the terms and provisions of the Sponsor Agreement shall control. For purposes of this Certificate of Incorporation, “Sponsor Agreement” means that certain Sponsor Agreement referred to in the BCA pursuant to which, among other things, the Sponsor Persons (as defined in the BCA) have agreed to (i) vote in favor of, and take all actions necessary to consummate, the BCA Transactions, (ii) the lock-up period and conditions described therein, (iii) following the consummation of the Mergers (as defined in the BCA), a certain amount of their Class A Common Stock will be subject to vesting restrictions described therein, (iv) as holder of a majority of the Class B Cayman Shares prior to the Domestication and a majority of the shares of Class C Common Stock at the filing of this Certificate of Incorporation with the Secretary of State of the State of Delaware to waive certain anti-dilution adjustments set forth in Section 17.3 of Altimar Cayman’s Memorandum and Articles of Association and Section 3(f) of this Certificate of Incorporation in connection with the transactions contemplated by the BCA and (y) to forfeit certain shares of Class A Common Stock received upon the automatic conversion of its shares of Class C Common Stock upon the closing of the transactions contemplated by the BCA for no consideration; and (v) to the conversion of Class C Common Stock into Class A Common Stock automatically upon consummation the BCA Transaction.

(g) No Transfer of any shares of Common Stock or shares of Preferred Stock may be made, except in compliance with the Investor Rights Agreement (as hereinafter defined) or Sponsor Agreement (if and as applicable) and applicable federal and state securities laws. No Transfer of shares of Class B Common Stock may be made, unless such transferor also Transfers an equal number of applicable Class A Units to the applicable transferee in accordance with the terms and conditions of the LLC Agreement. The Corporation may place customary restrictive legends on the certificates or book entries representing the shares of Common Stock and, if applicable, the shares of Preferred Stock subject to this Section 3(g) and remove such restrictive legends at the time the applicable restrictions under this Section 3(g) are no longer applicable to the shares of Common Stock or shares of Preferred Stock represented by such certificates or book entries. To the extent shares of Common Stock and, if applicable, shares of Preferred Stock subject to this Section 3(g) are uncertificated, the Corporation shall give notice of the restrictions set forth in this Section 3(g) in accordance with the DGCL. For purposes of this Certificate of Incorporation, “Transfer” has the meaning set forth in the Investor Rights Agreement or Sponsor Agreement, as applicable.

At each annual meeting of stockholders after the Commencement Date, directors elected to replace those of a class whose terms expire at such annual meeting shall be elected to hold office until the third succeeding annual meeting after their election and until their respective successors shall have been duly elected and qualified.

During any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal.

In recognition and anticipation that (i) certain of the directors, partners, principals, officers, members, managers and/or employees of CORE Industrial Partners, LLC (“CORE”) or its Affiliated Companies (as hereinafter defined) may serve as directors or officers of the Corporation and (ii) CORE and its Affiliated Companies engage and may continue to engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, and (iii) that the Corporation and its Affiliated Companies may engage in material business transactions with CORE and its Affiliated Companies, and that the Corporation is expected to benefit therefrom, the provisions of this ARTICLE EIGHT are set forth to regulate and define to the fullest extent permitted by law the conduct of certain affairs of the Corporation as they may involve CORE and/or its Affiliated Companies and/or their respective directors, partners, principals, officers, members, managers and/or employees, including any of the foregoing who serve as officers or directors of the Corporation (collectively, the “Exempted Persons”), and the powers, rights, duties and liabilities of the Corporation and its officers, directors and stockholders in connection therewith. As used in this Certificate of Incorporation, “Affiliated Companies” shall mean (a) in respect of CORE, any entity that controls, is controlled by or under common control with CORE (other than the Corporation and any company that is controlled by the Corporation) and any investment funds managed by CORE and (b) in respect of the Corporation, any company controlled by the Corporation.

Section 2. Competition and Corporate Opportunities. To the fullest extent permitted by applicable law, none of the Exempted Persons shall have any fiduciary duty to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Corporation or any of its Affiliated Companies, and no Exempted Person shall be liable to the Corporation or its stockholders for breach of any fiduciary duty solely by reason of any such activities of CORE, its Affiliated Companies or such Exempted Person. To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its Affiliated Companies, renounces any interest or expectancy of the Corporation and its Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to the Exempted Persons, even if the opportunity is one that the Corporation or its Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Exempted Person shall have no duty to communicate or offer such business opportunity to the Corporation or its Affiliated Companies and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation, any of its Affiliated Companies or its stockholders for breach of any fiduciary or other duty, as a director, officer or stockholder of the Corporation solely, by reason of the fact that CORE, its Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any of its Affiliated Companies. Notwithstanding anything to the contrary in this Section 2, the Corporation does not renounce any interest or expectancy it may have in any business opportunity that is expressly offered to any Exempted Person solely in his or her capacity as a director or officer of, or through his or her service to, or pursuant to a contract with, the Corporation, and not in any other capacity. Nothing in this Certificate of Incorporation shall be deemed to supersede any other agreement to which an Exempted Person may be a party or the rights of any other party thereto restricting such Exempted Person’s ability to have certain business interests or engage in certain business activities or ventures.

Section 3. Certain Matters Deemed Not Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this ARTICLE EIGHT, a corporate opportunity shall not be deemed to belong to the Corporation if it is a business opportunity the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 4. Amendment of this Article. Notwithstanding anything to the contrary elsewhere contained in this Certificate of Incorporation, subject to the rights of the holders of any series of Preferred Stock then outstanding,

A-9

and in addition to any vote required by applicable law, the affirmative vote of the holders of at least eighty percent (80%) of the voting power of the then outstanding shares of Voting Stock, voting together as a single class, shall be required to alter, amend or repeal, or to adopt any provision inconsistent with, this ARTICLE EIGHT; provided however, that, to the fullest extent permitted by law, neither the alteration, amendment or repeal of this ARTICLE EIGHT nor the adoption of any provision of this Certificate of Incorporation inconsistent with this ARTICLE EIGHT shall apply to or have any effect on the liability or alleged liability of any Exempted Person for or with respect to any activities or opportunities which such Exempted Person becomes aware prior to such alteration, amendment, repeal or adoption.

Section 5. Deemed Notice. Any person or entity purchasing or otherwise acquiring or holding any interest in any shares of capital stock of the Corporation shall be deemed to have notice of and to have consented to the provisions of this ARTICLE EIGHT.

Section 2. Business Combinations with Interested Stockholders. Notwithstanding any other provision in this Certificate of Incorporation to the contrary, the Corporation shall not engage in any Business Combination (as hereinafter defined), at any point in time at which the Common Stock is registered under Section 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), with any Interested Stockholder (as hereinafter defined) for a period of three years following the time that such stockholder became an Interested Stockholder, unless:

(a) prior to such time the Board of Directors (without taking into account the consent or approval of the Interested Stockholder or its designees if represented on the Board of Directors) approved either the Business Combination or the transaction which resulted in such stockholder becoming an Interested Stockholder;

(b) upon consummation of the transaction which resulted in such stockholder becoming an Interested Stockholder, such stockholder owned at least eighty-five percent (85%) of the Voting Stock of the Corporation outstanding at the time the transaction commenced, excluding for purposes of determining the Voting Stock outstanding (but not the outstanding Voting Stock owned by such Interested Stockholder) those shares owned (i) by Persons (as defined hereinafter) who are directors and also officers of the Corporation and (ii) employee stock plans of the Corporation in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or

(c) at or subsequent to such time, the Business Combination is approved by the Board of Directors and authorized at an annual or special meeting of stockholders, and not by written consent, by the affirmative vote of at least sixty-six and two-thirds percent (66 2/3%) of the outstanding Voting Stock which is not owned by such Interested Stockholder.

Section 3. Exceptions to Prohibition on Interested Stockholder Transactions. The restrictions contained in this ARTICLE NINE shall not apply if:

(a) a stockholder becomes an Interested Stockholder inadvertently and (i) as soon as practicable divests itself of ownership of sufficient shares so that the stockholder ceases to be an Interested Stockholder; and (ii) would not, at any time within the three-year period immediately prior to a Business Combination between the Corporation and such stockholder, have been an Interested Stockholder but for the inadvertent acquisition of ownership; or

A-10

(b) the Business Combination is proposed prior to the consummation or abandonment of and subsequent to the earlier of the public announcement or the notice required hereunder of a proposed transaction which (i) constitutes one of the transactions described in the second sentence of this Section 3(b) of ARTICLE NINE; (ii) is with or by a Person who either was not an Interested Stockholder during the previous three years or who became an Interested Stockholder with the approval of the Board of Directors (without taking into account the consent or approval of the Interested Stockholder or its designees if represented on the Board of Directors); and (iii) is approved by a majority of the directors then in office (but not less than one) who were directors prior to any Person becoming an Interested Stockholder during the previous three years or were recommended for election or elected to succeed such directors by a majority of such directors. The proposed transactions referred to in the preceding sentence are limited to (x) a merger or consolidation of the Corporation (except for a merger in respect of which, pursuant to Section 251(f) of the DGCL, no vote of the stockholders of the Corporation is required); (y) a sale, lease, exchange, mortgage, pledge, transfer or other disposition (in one transaction or a series of transactions), whether as part of a dissolution or otherwise, of assets of the Corporation or of any direct or indirect majority-owned subsidiary of the Corporation (other than to any direct or indirect wholly-owned subsidiary or to the Corporation) having an aggregate market value equal to fifty percent (50%) or more of either that aggregate market value of all of the assets of the Corporation determined on a consolidated basis or the aggregate market value of all the outstanding Stock (as hereinafter defined) of the Corporation; or (z) a proposed tender or exchange offer for fifty percent (50%) or more of the outstanding Voting Stock of the Corporation. The Corporation shall give not less than 20 days’ notice to all Interested Stockholders prior to the consummation of any of the transactions described in clause (x) or (y) of the second sentence of this Section 3(b) of ARTICLE NINE.

A-12

ownership of shares in excess of the fifteen percent (15%) limitation set forth herein is the result of action taken solely by the Corporation, provided that, for purposes of this clause (z) only, such Person shall be an Interested Stockholder if thereafter such Person acquires additional shares of Voting Stock of the Corporation, except as a result of further action by the Corporation not caused, directly or indirectly, by such Person; provided, that, for the purpose of determining whether a Person is an Interested Stockholder, the Voting Stock of the Corporation deemed to be outstanding shall include Stock deemed to be owned by the Person through application of this definition of “owned” but shall not include any other unissued Stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise;

(f) “Owner,” including the terms “own” and “owned,” when used with respect to any Stock, means a Person that individually or with or through any of its Affiliates or Associates beneficially owns such Stock, directly or indirectly; or has (A) the right to acquire such Stock (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the owner of Stock tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered Stock is accepted for purchase or exchange; or (B) the right to vote such Stock pursuant to any agreement, arrangement or understanding; provided, however, that a Person shall not be deemed the owner of any Stock because of such Person’s right to vote such Stock if the agreement, arrangement or understanding to vote such Stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more Persons; or (C) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in (B) of this Section 4(f) of ARTICLE NINE), or disposing of such Stock with any other Person that beneficially owns, or whose Affiliates or Associates beneficially own, directly or indirectly, such Stock;

(g) “Person” means any individual, corporation, partnership, unincorporated association or other entity;

(h) “Stock” means, with respect to any corporation, any capital stock of such corporation and, with respect to any other entity, any equity interest of such entity; and

(i) “Voting Stock” means, with respect to any corporation, Stock of any class or series entitled to vote generally in the election of directors and, with respect to any entity that is not a corporation, any equity interest entitled to vote generally in the election of the governing body of such entity. Every reference to a percentage of Voting Stock in this ARTICLE NINE shall refer to such percentage of the votes of such Voting Stock.

ARTICLE TEN

Section 1. Amendments to the Bylaws. Subject to the rights of holders of any series of Preferred Stock then outstanding, in furtherance and not in limitation of the powers conferred by law, the Bylaws may be amended, altered or repealed and new bylaws made by (i) the Board of Directors or (ii) in addition to any of the holders of any class or series of capital stock of the Corporation required herein (including any Preferred Stock Designation relating to any series of Preferred Stock), the Bylaws or applicable law, the affirmative vote of the holders of at least sixty-six and two-thirds percent (66 2/3%) of the voting power of the then outstanding Voting Stock, voting together as a single class.

Section 2. Amendments to this Certificate of Incorporation. Subject to the rights of holders of any series of Preferred Stock then outstanding, in addition to any affirmative vote of the holders of any particular class or series of the capital stock required by law, this Certificate of Incorporation, or otherwise, (a) no provision of ARTICLE FIVE, ARTICLE SIX, ARTICLE SEVEN, ARTICLE TEN or ARTICLE ELEVEN of this Certificate of Incorporation may be altered, amended or repealed in any respect, nor may any provision of this Certificate of

A-13

Incorporation inconsistent therewith be adopted, unless in addition to any other vote required by this Certificate of Incorporation or otherwise required by law, such alteration, amendment, repeal or adoption is approved by the affirmative vote of holders of at least sixty-six and two-thirds percent (66 2/3%) of the voting power of all outstanding shares of Voting Stock, voting together as a single class, at a meeting of the Corporation’s stockholders called for that purpose and (b) no provision of ARTICLE NINE of this Certificate of Incorporation may be altered, amended or repealed in any respect, nor may any provision of this Certificate of Incorporation inconsistent therewith be adopted, unless in addition to any other vote required by this Certificate of Incorporation or otherwise required by law, such alteration, amendment, repeal or adoption is approved by the affirmative vote of holders of at least eighty percent (80%) of the voting power of all outstanding shares of Voting Stock, voting together as a single class, at a meeting of the Corporation’s stockholders called for that purpose.

ARTICLE ELEVEN

Section 1. Exclusive Forum. Unless this Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, this Certificate of Incorporation or the Bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine; provided that for the avoidance of doubt, this provision, including for any “derivative action,” will not apply to suits to enforce a duty or liability created by the Securities Act, the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Failure to enforce the foregoing provisions would cause the Corporation irreparable harm and the Corporation shall be entitled to equitable relief, including injunctive relief and specific performance, to enforce the foregoing provisions. To the fullest extent permitted by law, any Person purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article Eleven.

Section 2. Notice. Any Person purchasing or otherwise acquiring or holding any interest in shares of capital stock of the Corporation (including, without limitation, shares of Common Stock) shall be deemed to have notice of and to have consented to the provisions of this ARTICLE ELEVEN.

A Delaware corporation

(Adopted as of                 , 2021)

ARTICLE I

OFFICES

Section 1. Offices. Fathom Digital Manufacturing Corporation (the “Corporation”) may have an office or offices other than its registered office at such place or places, either within or outside the State of Delaware, as the Board of Directors of the Corporation (the “Board of Directors”) may from time to time determine or the business of the Corporation may require. The registered office of the Corporation in the State of Delaware shall be as stated in the corporation’s certificate of incorporation as then in effect (the “Certificate of Incorporation”).

ARTICLE II

MEETINGS OF STOCKHOLDERS

Section 1. Place of Meetings. The Board of Directors may designate a place, if any, either within or outside the State of Delaware, as the place of meeting for any annual meeting or for any special meeting of stockholders.

Section 2. Annual Meeting. An annual meeting of the stockholders shall be held at such date and time as is specified by resolution of the Board of Directors. At the annual meeting, stockholders shall elect directors to succeed those whose terms expire at such annual meeting and transact such other business as properly may be brought before the annual meeting pursuant to Section 11 of this ARTICLE II of these Amended and Restated Bylaws (these “Bylaws”). The Board of Directors may postpone, reschedule or cancel any annual meeting of stockholders previously scheduled by the Board of Directors.

Section 3. Special Meetings. Special meetings of the stockholders may only be called in the manner provided in the Certificate of Incorporation. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. The Board of Directors may postpone, reschedule or cancel any special meeting of stockholders previously scheduled by the Board of Directors.

Section 4. Notice of Meetings. Whenever stockholders are required or permitted to take action at a meeting, notice of the meeting shall be given that shall state the place, if any, date, and time of the meeting of the stockholders, the means of remote communications, if any, by which stockholders and proxyholders not physically present may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given, not less than 10 nor more than 60 days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting, except as otherwise provided herein or required by law (meaning, here and hereinafter, as required from time to time by the General Corporation Law of the State of Delaware (the “DGCL”)) or the Certificate of Incorporation.

B-1

(a) Form of Notice. All such notices shall be delivered in writing or in any other manner permitted by the DGCL. If mailed, such notice shall be deemed given when deposited in the United States mail, postage prepaid, addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. If delivered by courier service, notice shall be deemed given at the earlier of when the notice is received or left at such stockholder’s address as the same appears on the records of the Corporation. If given by electronic mail, notice shall be deemed given when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by the DGCL. Notice to stockholders may also be given by other forms of electronic transmission consented to by the stockholder. If given by facsimile telecommunication, such notice shall be deemed given when directed to a number at which the stockholder has consented to receive notice by facsimile. If given by a posting on an electronic network together with separate notice to the stockholder of such specific posting, such notice shall be deemed given upon the later of (x) such posting and (y) the giving of such separate notice. If notice is given by any other form of electronic transmission, such notice shall be deemed given when directed to the stockholder. An affidavit of the secretary or an assistant secretary of the Corporation, the transfer agent of the Corporation or any other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(b) Waiver of Notice. Whenever notice is required to be given under any provisions of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver thereof, signed by the stockholder entitled to notice, or a waiver by electronic transmission given by the stockholder entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Neither the business to be transacted at, nor the purpose of, any meeting of the stockholders of the Corporation need be specified in any waiver of notice of such meeting. Attendance of a stockholder of the Corporation at a meeting of such stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened and does not further participate in the meeting.

(c) Notice by Electronic Transmission. Notwithstanding Section 4(a) of this ARTICLE II, a notice may not be given by electronic transmission from and after the time: (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices given by the Corporation; and (ii) such inability becomes known to the secretary or an assistant secretary of the Corporation or to the transfer agent or other person responsible for the giving of notice. However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. For purposes of these Bylaws, except as otherwise limited by applicable law, the term “electronic transmission” means any form of communication not directly involving the physical transmission of paper, including the use of, or participation in, one or more electronic networks or databases (including one or more distributed networks or databases), that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such recipient through an automated process. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation. A notice by electronic mail will include any files attached thereto and any information hyperlinked to a website if such electronic mail includes the contact information of an officer or agent of the corporation who is available to assist with accessing such files or information.

Section 5. List of Stockholders. The Corporation shall prepare, at least 10 days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, provided, however, if the record date for determining the stockholders entitled to vote is less than 10 days before the meeting date, the list shall reflect the stockholders entitled to vote as of the 10th day before the meeting date, arranged in alphabetical order and showing the address of each such stockholder and the number of shares registered in the name of each such stockholder. Nothing contained in this section shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least 10 days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. In the event

B-2

the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held at a place, the list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the list shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 5 or to vote in person or by proxy at any meeting of stockholders.

Section 6. Quorum. The holders of a majority in voting power of the outstanding capital stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by law, by the Certificate of Incorporation or these Bylaws. If a quorum is not present, the chair of the meeting or the holders of a majority of the voting power present in person or represented by proxy at the meeting and entitled to vote at the meeting may adjourn the meeting to another time and/or place from time to time until a quorum shall be present or represented by proxy. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a separate class or series, the holders of a majority in voting power of the outstanding stock of such class or series entitled to vote thereon shall constitute a quorum (as to such class or series) for the transaction of such item of business. A quorum once established at a meeting shall not be broken by the withdrawal of enough votes to leave less than a quorum.

Section 7. Adjourned Meetings. Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix a new record date for notice of such adjourned meeting, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors and, except as otherwise required by law, shall not be more than 60 days nor less than 10 days before the date of such adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date fixed for notice of such adjourned meeting.

Section 8. Vote Required. Subject to the rights of the holders of any series of preferred stock then outstanding, when a quorum has been established, all matters other than the election of directors shall be determined by the affirmative vote of the majority of voting power of capital stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter, unless by express provisions of the DGCL or other applicable law, the rules of any stock exchange upon which the Corporation’s securities are listed, any regulation applicable to the Corporation or its securities, the Certificate of Incorporation or these Bylaws a minimum or different vote is required, in which case such minimum or different vote shall be the required vote for such matter.

Section 12. Fixing a Record Date for Stockholder Meetings.

If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the Close of Business on the next day preceding the day on which notice is first given, or, if notice is waived, at the Close of Business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting in conformity herewith; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned

meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 12 at the adjourned meeting.

Section 13. Action by Stockholders Without a Meeting. So long as preferred stockholders of the Corporation have the right to act by written consent in accordance with Section 1 of ARTICLE SEVEN of the Certificate of Incorporation, the following provisions shall apply:

(a) Record Date. For the purpose of determining the stockholders entitled to consent to corporate action in writing without a meeting as may be permitted by the Certificate of Incorporation or the certificate of designation relating to any outstanding class or series of preferred stock, the Board of Directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than ten (10) (or the maximum number permitted by applicable law) days after the date on which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take action by written consent shall, by written notice delivered to the Secretary at the Corporation’s principal place of business during regular business hours, request that the Board of Directors fix a record date, which notice shall include the text of any proposed resolutions. Notices delivered pursuant to Section 13(a) of this ARTICLE II will be deemed received on any given day only if received prior to the Close of Business on such day (and otherwise shall be deemed received on the next succeeding Business Day). The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such written notice is properly delivered to and deemed received by the Secretary, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 13(a)). If no record date has been fixed by the Board of Directors pursuant to this Section 13(a) or otherwise within ten (10) days of receipt of a valid request by a stockholder, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required pursuant to applicable law, shall be the first date after the expiration of such ten (10) day time period on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation pursuant to Section 13(b); provided, however, that if prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall in such an event be at the Close of Business on the day on which the Board of Directors adopts the resolution taking such prior action.

(b) Generally. No written consent shall be effective to take the corporate action referred to therein unless written consents signed by a sufficient number of stockholders to take such action are delivered to the Corporation, in the manner required by this Section 13, within sixty (60) (or the maximum number permitted by applicable law) days of the date of the earliest dated consent delivered to the Corporation in the manner required by applicable law. The validity of any consent executed by a proxy for a stockholder pursuant to an electronic transmission transmitted to such proxy holder by or upon the authorization of the stockholder shall be determined by or at the direction of the Secretary. A written record of the information upon which the person making such determination relied shall be made and kept in the records of the proceedings of the stockholders. Any such consent shall be inserted in the minute book as if it were the minutes of a meeting of stockholders. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given by the Corporation (at its expense) to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consent signed by a sufficient number of holders to take the action were delivered to the Corporation.

Section 14. Conduct of Meetings.

do not convene in any one location, the annual meeting of the Board of Directors shall be held at the principal offices of the Corporation immediately after the annual meeting of the stockholders.

Section 3. Regular Meetings and Special Meetings. Regular meetings, other than the annual meeting, of the Board of Directors may be held without notice at such time and at such place as shall from time to time be determined by resolution of the Board of Directors and publicized among all directors. Special meetings of the Board of Directors may be called (i) by the Chair of the Board, if any, (ii) by the Secretary upon the written request of a majority of the directors then in office, (iii) prior to the first date on which CORE and its Affiliated Companies (as defined in the Certificate of Incorporation) first cease to beneficially own in the aggregate (directly or indirectly) shares of Common Stock representing at least 50% of the Original Amount (as defined in the Investor Rights Agreement), and if the Board of Directors then includes a director nominated or designated for nomination by CORE, by any director nominated or designated for nomination by CORE, or (iv) after the first date on which CORE and its Affiliated Companies first cease to beneficially own in the aggregate (directly or indirectly) shares of Common Stock representing at least 50% of the Original Amount, by written request of any two directors, and in each case shall be held at the place, if any, on the date and at the time as he, she or they shall fix. Any and all business may be transacted at a special meeting of the Board of Directors.

Section 4. Notice of Meetings. Notice of regular meetings of the Board of Directors need not be given except as otherwise required by law or these Bylaws. Notice of each special meeting of the Board of Directors, and of each regular and annual meeting of the Board of Directors for which notice is required, shall be given by the Secretary as hereinafter provided in this Section 4. Such notice shall be state the date, time and place, if any, of the meeting. Notice of any special meeting, and of any regular or annual meeting for which notice is required, shall be given to each director at least (a) twenty-four (24) hours before the meeting if by telephone or by being personally delivered or sent by overnight courier, telecopy, electronic transmission, email or similar means or (b) five (5) days before the meeting if delivered by mail to the director’s residence or usual place of business. Such notice shall be deemed to be delivered when deposited in the United States mail so addressed, with postage prepaid, or when transmitted if sent by telex, telecopy, electronic transmission, email or similar means. Neither the business to be transacted at, nor the purpose of, any special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting.

Section 5. Waiver of Notice. Any director may waive notice of any meeting of directors by a writing signed by the director or by electronic transmission. Any member of the Board of Directors or any committee thereof who is present at a meeting shall have waived notice of such meeting except when such member attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened and does not further participate in the meeting. Such member shall be conclusively presumed to have assented to any action taken unless his or her dissent shall be entered in the minutes of the meeting or unless his or her written dissent to such action shall be filed with the person acting as the secretary of the meeting before the adjournment thereof or shall be forwarded by registered mail to the secretary of the Corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to any member who voted in favor of such action.

Section 6. Chair of the Board, Quorum, Required Vote and Adjournment. The Board of Directors may elect a Chair of the Board. Notwithstanding the foregoing, for so long as CORE beneficially owns in the aggregate (directly or indirectly) at least 20% or more of the voting power of the then outstanding shares of capital stock of the Corporation then entitled to vote generally in the election of directors, the Chair of the Board of Directors may be designated by a majority of the directors nominated or designated for nomination by CORE. The Chair of the Board must be a director and may be an officer of the Corporation. Subject to the provisions of these Bylaws and the direction of the Board of Directors, he or she shall perform all duties and have all powers which are commonly incident to the position of Chair of the Board or which are delegated to him or her by the Board of Directors, preside at all meetings of the stockholders and Board of Directors at which he or she is present and have such powers and perform such duties as the Board of Directors may from time to time prescribe. If the Chair of the Board is not present at a meeting of the Board of Directors, the Chair’s designee shall preside at such

B-13

meeting, or if the Chair has made no such designation or if the designee is not present at such meeting, a majority of the directors present at such meeting shall elect one of the directors present at the meeting to so preside. At all meetings of the Board of Directors, a majority of the directors then in office shall constitute a quorum for the transaction of business, provided, however, that a quorum shall never be less than one-third the total number of directors. Unless a different vote is required by express provision of an applicable law, the Certificate of Incorporation or these Bylaws, the vote of a majority of directors present at a meeting at which a quorum is present shall be the act of the Board of Directors. At any meeting of the Board of Directors, business shall be transacted in such order and manner as the Board of Directors may from time to time determine. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may, to the fullest extent permitted by law, adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

Section 7. Committees.

(a) The Board of Directors may designate one or more committees, including an executive committee, consisting of one or more of the directors of the Corporation, and any committees required by the rules and regulations of such exchange as any securities of the Corporation are listed. The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Except to the extent restricted by applicable law or the Certificate of Incorporation, each such committee, to the extent provided by the DGCL and in the resolution creating it, shall have and may exercise all the powers and authority of the Board of Directors. Each such committee shall serve at the pleasure of the Board of Directors. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors upon request.

(b) Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. All matters shall be determined by a majority vote of the members present at a meeting at which a quorum is present. Unless otherwise provided in such a resolution, in the event that a member and that member’s alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, the member or members present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member.

Section 8. Action by Written Consent. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of the Board of Directors or such committee, as the case may be, consent thereto in writing or by electronic transmission. After the action is taken, the consent or consents relating thereto shall be filed with the minutes of proceedings of the board or committee in the same paper form or electronic form as the minutes are maintained.

Section 9. Compensation. The Board of Directors shall have the authority to fix the compensation, including fees, reimbursement of expenses and equity compensation, of directors for services to the Corporation in any capacity, including for attendance of meetings of the Board of Directors or participation on any committees. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 10. Reliance on Books and Records. A member of the Board of Directors, or a member of any committee designated by the Board of Directors shall, in the performance of such member’s duties, be fully protected in relying in good faith upon records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of the Corporation’s officers or employees, or committees of the Board of

B-14

Directors, or by any other person as to matters the member reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation.

Section 11. Telephonic and Other Meetings. Unless restricted by the Certificate of Incorporation, any one or more members of the Board of Directors or any committee thereof may participate in a meeting of the Board of Directors or such committee by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other. Participation by such means shall constitute presence in person at a meeting.

ARTICLE V

CERTIFICATES OF STOCK

Section 1. Form. The shares of stock of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution that some or all of any or all classes or series of its stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. If shares are represented by certificates, the certificates shall be in such form as required by applicable law and as determined by the Board of Directors. Each certificate shall certify the number of shares owned by such holder in the Corporation and shall be signed by, or in the name of the Corporation by two authorized officers of the Corporation including, but not limited to, the Chair of the Board (if an officer), the President, a Vice President, the Treasurer, the Secretary and an Assistant Secretary of the Corporation. Any or all signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed, or whose facsimile signature or signatures have been used on, any such certificate or certificates shall cease to be such officer, transfer agent or registrar of the Corporation whether because of death, resignation or otherwise before such certificate or certificates have been issued by the Corporation, such certificate or certificates may nevertheless be issued as though the person or persons who signed such certificate or certificates or whose facsimile signature or signatures have been used thereon had not ceased to be such officer, transfer agent or registrar of the Corporation at the date of issue. All certificates for shares shall be consecutively numbered or otherwise identified. The Board of Directors may appoint a bank or trust company organized under the laws of the United States or any state thereof to act as its transfer agent or registrar, or both in connection with the transfer of any class or series of securities of the Corporation. The Corporation, or its designated transfer agent or other agent, shall keep a book or set of books to be known as the stock transfer books of the Corporation, containing the name of each holder of record, together with such holder’s address and the number and class or series of shares held by such holder and the date of issue. When shares are represented by certificates, the Corporation shall issue and deliver to each holder to whom such shares have been issued or transferred, certificates representing the shares owned by such holder, and shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation or its designated transfer agent or other agent of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the

B-17

duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates and record the transaction on its books. When shares are not represented by certificates, shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, with such evidence of the authenticity of such transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps, and within a reasonable time after the issuance or transfer of such shares, the Corporation shall, if required by applicable law, send the holder to whom such shares have been issued or transferred a written statement of the information required by applicable law. Unless otherwise provided by applicable law, the Certificate of Incorporation, Bylaws or any other instrument, the rights and obligations of the holders of uncertificated stock and the rights and obligations of the holders of certificates representing stock of the same class and series shall be identical.

Section 2. Lost Certificates. The Corporation may issue or direct a new certificate or certificates or uncertificated shares to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the owner of the lost, stolen or destroyed certificate. When authorizing such issue of a new certificate or certificates or uncertificated shares, the Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond in such sum as it may direct, sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Section 3. Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its records as the owner of shares of stock to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner, except as otherwise required by applicable law. The Corporation shall not be bound to recognize any equitable or other claim to or interest in such share or shares of stock on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise required by applicable law.

Section 4. Fixing a Record Date for Purposes Other Than Stockholder Meetings or Actions by Written Consent. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes of any other lawful action (other than stockholder meetings and stockholder written consents which are expressly governed by Sections 12 and 13 of ARTICLE II hereof), the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the Close of Business on the day on which the Board of Directors adopts the resolution relating thereto.

ARTICLE VI

Notwithstanding the foregoing, no seal shall be required by virtue of this Section.

Section 6. Voting Securities Owned By Corporation. Voting securities in any other corporation or entity held by the Corporation shall be voted by the Chair of the Board, Chief Executive Officer, the President or the Chief Financial Officer, unless the Board of Directors specifically confers authority to vote with respect thereto, which authority may be general or confined to specific instances, upon some other person or officer. Any person authorized to vote securities shall have the power to appoint proxies, with general power of substitution.

Section 7. Facsimile Signatures. In addition to the provisions for use of facsimile signatures elsewhere specifically authorized in these Bylaws and subject to applicable law, facsimile signatures of any officer or officers of the Corporation may be used.

Section 9. Inconsistent Provisions. In the event that any provision (or part thereof) of these Bylaws is or becomes inconsistent with any provision of the Certificate of Incorporation, the DGCL, any other applicable law or the Investor Rights Agreement, the provision (or part thereof) of these Bylaws shall be deemed to have been revised to conform to the applicable provision of the Certificate of Incorporation, the DGCL, other applicable law or the Investor Rights Agreement, as the case may be, the applicable provisions of which shall be deemed incorporated herein by reference, so as to eliminate any such inconsistency.

ARTICLE VII

INDEMNIFICATION

Section 1. Right to Indemnification and Advancement. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes or penalties under the Employee Retirement Income Security Act of 1974, as amended from time to

B-19

time (“ERISA”) and any other penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s heirs, executors and administrators; provided, however, that, except as provided in this Section 2 of this ARTICLE VII with respect to proceedings to enforce rights to indemnification and advance of expenses (as defined below), the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized in the specific case by the Board of Directors of the Corporation. The rights to indemnification and advance of expenses conferred in this Section 1 of ARTICLE VII shall be contract rights. In addition to the right to indemnification conferred herein, an indemnitee shall also have the right, to the fullest extent not prohibited by law, to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (an “advance of expenses”); provided, however, that if and to the extent that the DGCL requires, an advance of expenses shall be made only upon delivery to the Corporation of an undertaking (an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 1 or otherwise. The Corporation may also, by action of its Board of Directors, provide indemnification and advancement to employees and agents of the Corporation. Any reference to an officer of the Corporation in this ARTICLE VII shall be deemed to refer exclusively to the Chair of the Board of Directors, Chief Executive Officer, President, Secretary and Treasurer of the Corporation appointed pursuant to ARTICLE IV, and to any Vice President, Assistant Secretary, Assistant Treasurer or other officer of the Corporation appointed by the Board of Directors pursuant to ARTICLE IV of these By-laws, and any reference to an officer of any other enterprise shall be deemed to refer exclusively to an officer appointed by the board of directors or equivalent governing body of such other entity pursuant to the certificate of incorporation and bylaws or equivalent organizational documents of such other enterprise. The fact that any person who is or was an employee of the Corporation or an employee of any other enterprise has been given or has used the title of “Vice President” or any other title that could be construed to suggest or imply that such person is or may be an officer of the Corporation or of such other enterprise shall not result in such person being constituted as, or being deemed to be, an officer of the Corporation or of such other enterprise for purposes of this ARTICLE VII.

Section 2. Procedure for Indemnification. Any claim for indemnification or advance of expenses by an indemnitee under this Section 2 of ARTICLE VII shall be made promptly, and in any event within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), upon the written request of the indemnitee. If the Corporation denies a written request for indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the indemnitee has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), the right to indemnification or advances as granted by this ARTICLE VII shall be enforceable by the indemnitee in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation to the fullest extent permitted by applicable law. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 1 of this ARTICLE VII, if any, has been tendered to the Corporation) that the claimant has not met the applicable standard of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proof shall be on the Corporation to the fullest extent permitted by law. Neither the failure of the Corporation (including its Board of Directors, a committee thereof, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

B-20

Section 3. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was or has agreed to become a director, officer, employee or agent of the Corporation or is or was serving at the request of the Corporation as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify such person against such expenses, liability or loss under the DGCL.

Section 4. Service for Subsidiaries. Any person serving as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at least 50% of whose equity interests are owned by the Corporation (a “subsidiary” for purposes of this ARTICLE VII) shall be conclusively presumed to be serving in such capacity at the request of the Corporation.

Section 5. Reliance. Persons who served as directors or officers of Altimar Cayman (as defined in the Certificate of Incorporation), and Persons who after the date of the adoption of this provision become or remain directors or officers of the Corporation or who, while a director or officer of the Corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this ARTICLE VII in entering into or continuing such service. To the fullest extent permitted by law, the rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof. Any amendment, alteration or repeal of this ARTICLE VII that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

Section 6. Non-Exclusivity of Rights; Continuation of Rights of Indemnification. The rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall not be exclusive of any other right which any person may have or hereafter acquire under the Certificate of Incorporation or under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise. All rights to indemnification under this ARTICLE VII shall be deemed to be a contract between the Corporation and each director or officer of the Corporation who serves or served in such capacity at any time while this ARTICLE VII is in effect. Any repeal or modification of this ARTICLE VII or repeal or modification of relevant provisions of the DGCL or any other applicable laws shall not in any way diminish any rights to indemnification and advancement of expenses of such director or officer or the obligations of the Corporation arising hereunder with respect to any proceeding arising out of, or relating to, any actions, transactions or facts occurring prior to the final adoption of such repeal or modification.

Section 7. Merger or Consolidation. For purposes of this ARTICLE VII, references to the “Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this ARTICLE VII with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.

Section 8. Savings Clause. To the fullest extent permitted by law, if this ARTICLE VII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and advance expenses to each person entitled to indemnification under Section 1 of this ARTICLE VII as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, ERISA

B-21

excise taxes and penalties and any other penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification and advancement of expenses is available to such person pursuant to this ARTICLE VII to the fullest extent permitted by any applicable portion of this ARTICLE VII that shall not have been invalidated.

ARTICLE VIII

AMENDMENTS

Until a duly, completely and validly executed Letter of Transmittal has been delivered as contemplated by this Section 4.05, from and after the Closing, each former Fathom Unit and each former equity interest in a Fathom Blocker shall be deemed at all times to represent only the right to receive upon delivery of such Letter of Transmittal the consideration to which such Fathom Blocker Owner or Continuing Fathom Unitholder is entitled pursuant to Article III. For the avoidance of doubt, delivery of any Letter of Transmittal shall not be a condition to or otherwise delay the Closing.

The Parties shall use commercially reasonable efforts to make alternative arrangements for such disclosure where the restrictions in the preceding sentence apply.

Fathom acknowledges that substantially all of Altimar’s assets consist of the cash proceeds of its initial public offering (the “IPO”) and/or certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon), and all of those proceeds were deposited in the Trust Account for the benefit of Altimar’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of Altimar entering into this Agreement and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, each of Fathom and the Fathom Blockers hereby irrevocably waives (on its own behalf and shall cause each of their respective Subsidiaries and controlled Affiliates to waive) any and all right, title and interest, or any claim of any kind it has or may have in the future, as a result of or arising out of this Agreement or the transactions contemplated hereby, in or to any monies in the Trust Account (or distributions therefrom to Altimar public stockholders upon the redemption of their shares, the “Trust Distributions”), and agrees not to seek recourse against the Trust Account or the Trust Distributions, for any reason whatsoever as a result of or arising out of this Agreement. Each of Fathom and the Fathom Blockers agrees and acknowledges that such irrevocable waiver is material to this Agreement and specifically relied upon by Altimar to induce Altimar to enter in this Agreement, and Fathom and the Fathom Blockers further intend and understand such waiver to be valid, binding and enforceable against Fathom and the Fathom Blockers and each of their respective Subsidiaries and controlled Affiliates that they have the authority to bind under applicable Law.

(c) Fathom and the Fathom Blockers acknowledge and agree that the Fathom Written Consent and the Fathom Blockers Written Consents that have been delivered in connection with this Agreement shall become automatically effective upon the Form S-4 becoming effective.

Section 8.05 Equityholder Notices; Information Statement.

Prior to the Closing, except for this Agreement and any other Transaction Agreements, Fathom and the Fathom Blockers shall take, and cause to be taken, all actions necessary to cause all Fathom Related Party Transactions and all Blocker Related Party Transactions to be terminated as of or prior to the Closing without any further cost or Liability to Altimar or its Subsidiaries following the Closing, other than as set forth on Schedule 8.06 of the Fathom Schedules.

Fathom shall, and shall cause its Affiliates and Representatives to, immediately cease any and all existing discussions or negotiations with any Person conducted prior to the Execution Date with respect to, or which is reasonably likely to give rise to or result in, an Acquisition Transaction.

ARTICLE IX

COVENANTS OF ALTIMAR

Section 9.01 Indemnification and Insurance.

(a) From and after the Fathom Effective Time, Altimar agrees that (to the maximum extent permitted by applicable Law) it shall indemnify and hold harmless each present and former director, manager and officer of Fathom, the Fathom Blockers and Altimar and each of their respective Subsidiaries against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or Liabilities incurred in connection with any Action, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the Fathom Effective Time, whether asserted or claimed prior to, at or after such effective time, to the fullest extent that Fathom, the Fathom Blockers, Altimar or their respective Subsidiaries, as the case may be, would have been permitted under applicable Law and their respective certificate of incorporation, bylaws or other organizational documents in effect on the Execution Date to indemnify such Person (including the advancing of expenses as incurred to the fullest extent permitted under applicable Law). Without limiting the foregoing, following the Closing, Altimar shall and shall cause each of its Subsidiaries (including Fathom) to, (i) maintain for a period of not less than six (6) years from the Closing provisions in its certificate of incorporation, bylaws and other organizational documents concerning the indemnification and exoneration (including provisions relating to expense advancement) of officers and directors/managers that are no less favorable to those Persons than the provisions of such certificates of incorporation, bylaws and other organizational documents as of the Execution Date and (ii) not amend, repeal or otherwise modify such provisions in any respect that would adversely affect the rights of those Persons thereunder, in each case, except as required by Law.

(b) For a period of six (6) years from the Closing, Altimar shall, or shall cause one or more of its Subsidiaries to, maintain in effect directors’ and officers’ liability insurance covering those Persons who are

C-72

currently covered by Altimar’s, a Fathom Blocker’s, Fathom’s or any of their respective Subsidiaries’ directors’ and officers’ liability insurance policies (true, correct and complete copies of which have been heretofore made available to Fathom or Altimar, as applicable, or their respective agents or representatives) on terms not less favorable than the terms of such current insurance coverage, except that in no event shall Altimar or its Subsidiaries be required to pay an annual premium for such insurance in excess of 300% of the aggregate annual premium payable by the Fathom Blockers, Fathom and its Subsidiaries and Altimar and its Subsidiaries for such insurance policy for the year ended December 31, 2021; provided, however, that Fathom and Altimar may, in the alternative, cause coverage to be extended under such Fathom Blocker’s, Fathom’s or Altimar’s, as applicable, current directors’ and officers’ liability insurance by obtaining a six-year “tail” policy containing terms not less favorable than the terms of such current insurance coverage with respect to claims existing or occurring at or prior to the Closing (the “D&O Tail”), except that in no event shall Altimar or its Subsidiaries be required to pay an annual premium for such insurance in excess of 300% of the aggregate annual premium payable by such Fathom Blocker, Fathom and its Subsidiaries or Altimar and its Subsidiaries, as applicable, for such current insurance.

(c) Altimar, the Fathom Blockers and Fathom hereby acknowledge (on behalf of themselves and their respective Subsidiaries) that the indemnified Persons under this Section 9.01 may have certain rights to indemnification, advancement of expenses and/or insurance provided by current equityholders, members, or other Affiliates of such equityholders or members (“Indemnitee Affiliates”) separate from the indemnification obligations of Altimar, the Fathom Blockers, Fathom and their respective Subsidiaries hereunder. The Parties hereby agree, following the Closing, (i) that Altimar, Fathom and their respective Subsidiaries are the indemnitors of first resort (i.e., its obligations to the indemnified Persons under this Section 9.01 are primary and any obligation of any Indemnitee Affiliate to advance expenses or to provide indemnification for the same expenses or Liabilities incurred by the indemnified Persons under this Section 9.01 are secondary), (ii) that Altimar, Fathom and their respective Subsidiaries shall be required to advance the full amount of expenses incurred by the indemnified Persons under this Section 9.01 and shall be liable for the full amount of all expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and required by Altimar’s or Fathom’s and their respective Subsidiaries’ governing documents or any director or officer indemnification agreements, without regard to any rights the indemnified Persons under this Section 9.01 may have against any Indemnitee Affiliate, subject to such indemnified Person providing an undertaking to refund any and all such advances to Altimar in the event that it is determined (by a final non-appealable judgment) that such indemnified Person is not entitled to indemnification, and (iii) except with respect to employees and as set forth in the immediately preceding clause (ii), that the Parties (on behalf of themselves and their respective Subsidiaries) irrevocably waive, relinquish and release the Indemnitee Affiliates from any and all claims against the Indemnitee Affiliates for contribution, subrogation or any other recovery of any kind in respect thereof.

(d) Notwithstanding anything contained in this Agreement to the contrary, this Section 9.01 shall survive the consummation of the Mergers indefinitely and shall be binding, jointly and severally, on the Altimar Surviving Entity and the Fathom Surviving Entity, and all successors and assigns of the Altimar Surviving Entity and the Fathom Surviving Entity. In the event that the Altimar Surviving Entity or the Fathom Surviving Entity or any of their respective successors or assigns consolidates with or merges into any other Person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or transfers or conveys all or substantially all of its properties and assets to any Person, then, and in each such case, Altimar shall take reasonable best efforts to ensure that proper provision shall be made so that the successors and assigns of the Altimar Surviving Entity or the Fathom Surviving Entity, as the case may be, shall succeed to the obligations set forth in this Section 9.01.

Section 9.02 Conduct of Altimar During the Interim Period.

(a) During the Interim Period, except as set forth on Schedule 9.02 of the Altimar Schedules or as contemplated by this Agreement or as consented to by Fathom in writing (which consent shall not be

(v) (A) enter into, renew or amend in any material respect, any transaction or Contract relating to Altimar Transaction Expenses if such entry, renewal or amendment would result in additional Altimar Transaction Expenses that, individually or in the aggregate, exceed $5,000,000 (and in all cases subject to Section 9.02(a)(iv)), (B) cause or permit any Altimar Transaction Expenses of the type contemplated by clauses (i) through (viii) of the definition thereof to be incurred if the sum of (1) the amounts contemplated by clauses (i) through (viii) of the definition thereof, up to a maximum amount of $25,700,000, plus (2) the amounts contemplated by clauses (ix), (x) and (xi) of the definition thereof, exceeds $27,000,000 in the aggregate, or (C) incur any material Altimar Transaction Expenses of the type contemplated by clauses (x) or (xi) of the definition thereof without the prior written consent of Fathom (not to be unreasonably withheld);

Prior to the Closing, Altimar shall exercise, consistent with the terms and conditions of this Agreement, control over its business.

If, at any time prior to obtaining the approval of the Altimar Stockholder Matters in the Special Meeting, the Altimar Board determines in good faith, in response to an Intervening Event, after consultation with its outside legal counsel, that the failure to make an Altimar Change in Recommendation would be a breach of its fiduciary duties under applicable Law, the Altimar Board may, prior to obtaining the approval of the Altimar Stockholder Matters in the Special Meeting, make an Altimar Change in Recommendation; provided, that Altimar will not be entitled to make, or agree or resolve to make, an Altimar Change in Recommendation unless (i) Altimar delivers to Fathom a written notice (an “Intervening Event Notice”) advising Fathom that the Altimar Board proposes to take such action and containing the material facts underlying the Altimar Board’s determination that an Intervening Event has occurred, and (ii) at or after 5:00 p.m., New York City time, on the fifth (5th) Business Day immediately following the day on which Altimar delivered the Intervening Event Notice (such period from the time the Intervening Event Notice is provided until 5:00 p.m. New York City time on the fifth (5th) Business Day immediately following the day on which Altimar delivered the Intervening Event Notice (it being understood that any material development with respect to an Intervening Event shall require a new notice but with an additional four (4) Business Day (instead of five (5) Business Day) period from the date of such notice), the “Intervening Event Notice Period”), the Altimar Board reaffirms in good faith (after consultation with its outside legal counsel) that the failure to make an Altimar Change in Recommendation would be a breach of its fiduciary duties under applicable Law. Altimar will use its reasonable best efforts to cause its Representatives to, during the Intervening Event Notice Period, engage in good faith negotiations with Fathom and its Representatives to make such adjustments in the terms and conditions of this Agreement so as to obviate the need for an Altimar Change in Recommendation.

C-78

(including, with respect to filings pursuant to the HSR Act, by its “Ultimate Parent Entities”, as that term is defined in the HSR Act) as promptly as reasonably practicable and advisable to any Governmental Authority information and documents relating to such party as requested by such Governmental Authority or necessary, proper or advisable to permit consummation of the Transactions, including filing any notification and report form and related material required under the HSR Act, any necessary or appropriate filings pursuant to FINRA Rule 1017 and any other filing or notice that may be required with any other Governmental Authority as promptly as reasonably practicable and advisable after the Execution Date (and, in the case of the initial filing under the HSR Act and FINRA, no later than 10 Business Days after the Execution Date), and thereafter to respond as promptly as reasonably practicable and advisable to any request for additional information or documentary material relating to such party that may be made (including under the HSR Act and any similar Antitrust Law regarding preacquisition notifications for the purpose of competition reviews or by FINRA).

In furtherance and not in limitation of the foregoing, each Party shall provide, or cause to be provided, all agreements, documents, instruments, affidavits, statements or information that may be required or requested by any Governmental Authority relating to (i) such Party (including any of its directors, officers, employees, partners, members, shareholders or control persons) and (ii) such Party’s structure, ownership, businesses, operations, regulatory and legal compliance, assets, liabilities, financing, financial condition or results of operations, or any of its or their directors, officers, employees, partners, members, shareholders or Affiliates.

(c) If any objections are asserted with respect to the Transactions under any applicable Law or if any Action is instituted by any Governmental Authority or any private party challenging any of the Transactions as violative of any applicable Law, each of the Parties shall cooperate with one another in good faith and use their reasonable best efforts to: (i) oppose or defend against any action to prevent or enjoin consummation of this Agreement (and the Transactions), and (ii) take such action as reasonably necessary to overturn any regulatory action by any Governmental Authority to prevent or enjoin consummation of this Agreement (and the Transactions), including by defending any Action brought by any Governmental Authority in order to avoid entry of, or to have vacated, overturned or terminated, including by appeal if necessary, in order to resolve any such objections or challenge as such Governmental Authority or private party may have to any of the Transactions under such applicable Law so as to permit the consummation of the Transactions in their entity; provided, however, that any decision by the Parties to litigate in connection with such matters must be mutually agreed by Altimar and Fathom.

(d) Notwithstanding the foregoing, Altimar shall, and shall cause its controlled Affiliates to, take any and all actions necessary to obtain any authorization, consent or approval of a Governmental Authority (including in connection with any Governmental Filings) necessary or advisable so as to enable the consummation of the Transactions to occur as expeditiously as possible (and in any event, no later than the Termination Date) and to resolve, avoid or eliminate any impediments or objections, if any, that may be asserted with respect to the Transactions under any Law, or to otherwise oppose, avoid the entry of, or to effect the dissolution of, any order, decree, judgment, preliminary or permanent injunction that would otherwise have the effect of preventing, prohibiting, restricting, or delaying the consummation of the Transactions, including: (i) proposing, negotiating, committing to and effecting, by consent decree, hold separate order or otherwise, the sale, divestiture, licensing or disposition of, or holding separate of, businesses, product lines, rights or assets of Altimar or its controlled Affiliates and any interest therein

C-79

(including entering into customary ancillary agreements relating to any such sale, divestiture, licensing or disposition of such businesses, product lines, rights or assets) and (ii) otherwise taking or committing to take actions that after the Closing Date would limit Altimar’s or its controlled Affiliates’ freedom of action with respect to, or its ability to retain or control, one or more of the businesses, product lines, rights or assets of Altimar and its controlled Affiliates or interest therein, in each case as may be required in order to enable the consummation of the Transactions to occur as expeditiously as possible (and in any event no later than the Termination Date).

(e) From the Execution Date until Closing, Altimar shall not acquire or agree to acquire, by merging with or into or consolidating with, or by purchasing a substantial portion of the assets of or any equity in, or by any other manner, any assets or Person, or take any other action, if the execution and delivery of a definitive agreement relating to, or the consummation of, such acquisition, or the taking of any other action, could in any material respect (individually or in the aggregate): (i) impose any delay in obtaining, or increase the risk of not obtaining, consents of a Governmental Authority necessary to consummate the Transactions or the expiration or termination of any applicable waiting period, (ii) increase the risk of a Governmental Authority seeking or entering a Governmental Order prohibiting the consummation of the Transactions, (iii) increase the risk of not being able to remove any such Governmental Order on appeal or otherwise, or (iv) otherwise prevent or delay the consummation of the Transactions.

Notwithstanding anything in this Agreement or any Transaction Agreement to the contrary, any Seller Related Person or Altimar Related Person may designate any materials provided to a Governmental Authority that contain sensitive or confidential information in respect of such Seller Related Person or Altimar Related Person or any of their respective Affiliates, as applicable, as such “Seller Related Person only” or “Altimar Related Person only” and such materials and the information contained therein shall not be disclosed to any other Person or Governmental Authority without such Seller Related Person’s or Altimar Related Person’s, as applicable, prior written consent, and such Seller Related Person may provide that any such sensitive or confidential information may only be provided on an outside counsel-only basis or directly to the applicable Governmental Authority requesting such information and all appearances, submissions, presentations, briefs, and proposals made or submitted by or on behalf of such Seller Related Person or Altimar Related Person or any of their respective Affiliates before any Governmental Authority shall be controlled by such Seller Related Person or Altimar Related Person, as applicable. No breach or violation shall be deemed to have occurred as a result of the failure of any Seller Related Person or Altimar Related Person to provide information not required to be provided by this provision or any other provision of this Agreement.

(ii) Altimar shall duly call, give notice of, convene and hold the Special Meeting as promptly as practicable after the Execution Date, in accordance with applicable Law. Notwithstanding anything to the contrary contained in this Agreement, Altimar shall be entitled to (and, in the case of the following clauses (ii) and (iii), at the request of Fathom, shall) postpone or adjourn the Special Meeting for a period of no longer than 29 days (without Fathom’s prior written consent): (i) to ensure that any supplement or amendment to the Proxy Statement/Consent Solicitation Statement/Prospectus that the board of directors of Altimar has determined in good faith is required by applicable Law is disclosed to Altimar’s stockholders and for such supplement or amendment to be promptly disseminated to Altimar’s stockholders prior to the Special Meeting; (ii) if, as of the time for which the Special Meeting is originally scheduled (as set forth in the Proxy Statement/Consent Solicitation Statement/Prospectus), there are insufficient Cayman Class A Shares and Cayman Class B Shares represented (either in person or by proxy) to constitute a quorum necessary to conduct the business to be conducted at the Special Meeting; or (iii) in order to solicit additional proxies from stockholders for purposes of obtaining approval of the Required Altimar Stockholder Approvals or satisfying the condition set forth in Section 11.03(c) hereof; provided, that in the event of any such postponement or adjournment, the Special Meeting shall be reconvened as promptly as practicable following such time as the matters described in such clauses have been resolved.

(a) Altimar and Fathom shall each pay fifty percent (50%) of all transfer, documentary, sales, use, stamp, registration, value added or other similar Taxes incurred in connection with the Transactions (collectively, the “Transfer Taxes”) and file all necessary Tax Returns with respect to all Transfer Taxes, and, if required by applicable Law, the Parties shall, and shall cause their respective Affiliates to, join in the execution of any such Tax Returns and other document.

(b) For U.S. federal income tax purposes (and for purposes of any applicable state or local income tax that follows U.S. federal income tax treatment), each of the Parties intends that (i) the Domestication will constitute a “reorganization” within the meaning of Section 368(a)(1)(F) of the Code, (ii) the conversion of Altimar Class C Common Stock into Altimar Class A Common Stock will constitute a “reorganization” within the meaning of Section 368(a)(1)(E) of the Code, (iii) in connection with the Blocker Mergers and

the Blocker Altimar Mergers, (A) (1) the Fathom Blocker 1 Merger and the Fathom Blocker 1 Altimar Merger, (2) the Fathom Blocker 2 Merger and the Fathom Blocker 2 Altimar Merger, and (3) the Fathom Blocker 3 Merger and the Fathom Blocker 3 Altimar Merger, each taken together in the manner consistent with Revenue Ruling 2001-46, will each separately qualify as a “reorganization” within the meaning of Section 368(a) of the Code (for the avoidance of doubt, with each of clauses (1), (2) and (3) separately constituting a “reorganization” within the meaning of Section 368(a) of the Code), (B) the issuance of the applicable Fathom Earnout Consideration will be treated for Tax purposes as eligible for non-recognition treatment under the Code and the Treasury Regulations in connection with the reorganizations described in clause (A) and will not be treated as “other property” within the meaning of Section 356 of the Code and (C) the Closing Cash Consideration payable to the Fathom Blocker Owners as set forth in the Allocation Schedule and the right to receive certain payments under the Tax Receivable Agreement will be treated as “other property” within the meaning of Section 356 of the Code in connection with the reorganizations described in clause (A), (iv) in connection with the Fathom Merger, (A) the acquisition of interests in Fathom from the Continuing Fathom Unitholders by Altimar for the Closing Cash Consideration as set forth in the Allocation Schedule and the right to receive certain payments under the Tax Receivable Agreement (the “Cash Sale”) will be treated as a transaction described in Section 741 of the Code giving rise to an adjustment to Altimar’s basis in the direct and indirect assets of Fathom pursuant to Section 743 of the Code and (B) the contribution of cash by Altimar to Fathom as contemplated by Section 2.09 will be treated as an acquisition of an interest in Fathom by Altimar in a transaction governed by Section 721 of the Code, (v) the receipt by the Continuing Fathom Unitholders of New Fathom Class A Units and the applicable Fathom Earnout Consideration shall be treated as not giving rise to an exchange for U.S. federal income tax purposes and (vi) the payments and contribution of the Available Cash Amount contemplated by Section 4.02 will be treated as an acquisition of an interest in Fathom by Altimar in a transaction governed by Section 721 of the Code (clauses (i) through (vi), together, the “Intended Tax Treatment”). This Agreement is hereby adopted as and shall constitute a “plan of reorganization” within the meaning of Treasury Regulations Section 1.368-2(g) with respect to the Blocker Mergers and the Blocker Altimar Mergers.

(c) Altimar and Fathom and its Subsidiaries intend for the Transactions to qualify for the Intended Tax Treatment and will not take any inconsistent position on any Tax Return or during the course of any audit, litigation or other proceeding with respect to Taxes, except as otherwise required by a determination within the meaning of Section 1313(a) of the Code or a change in applicable Law after the date hereof, based on a breach of a representation or covenant in this Agreement, or as the result of any action required pursuant to this Agreement. Each of the Parties agrees to use reasonable best efforts to promptly notify the Unitholder Representative of any challenge to the Intended Tax Treatment by any Governmental Authority.

(d) Except as otherwise required pursuant to this Agreement, no Party shall take or cause to be taken any action, or knowingly fail to take or cause to be taken any action, which action or failure to act would reasonably be expected to prevent the Transactions from so qualifying for the Intended Tax Treatment.

(e) The Unitholder Representative shall prepare, or cause to be prepared, at the expense of Fathom, all income Tax Returns with respect to Pass-Through Income Taxes of Fathom (and its Subsidiaries) for any Pre-Closing Tax Period (other than the portion of any Straddle Period ending on the Closing Date) that are due after the Closing Date (taking into account applicable extensions) (each, a “Pass-Through Return”). Each Pass-Through Return shall be prepared in a manner consistent with Fathom’s (or such Subsidiary’s) past practice except to the extent not “more likely than not” to be upheld under applicable Law. Each Pass-Through Return, as prepared by the Unitholder Representative, shall be submitted to Altimar for its review and comment no later than 30 days prior to its due date (taking into account applicable extensions). The Unitholder Representative shall consider in good faith any timely comments received from Altimar with respect to such Pass-Through Returns.

(f) All Tax Returns of Fathom and its Subsidiaries other than Pass-Through Returns described in Section 10.04(e) that are due after the Closing Date (taking into account applicable extensions) shall be prepared and filed in accordance with the terms of the Fathom Operating Agreement, provided that

C-84

Fathom’s Pass-Through Returns for the taxable year that includes the Closing Date shall include an election under Section 754 of the Code to the extent such an election is not already in effect.

(g) In the event of any proposed audit, adjustment, assessment, examination, claim or other controversy or proceeding relating to Pass-Through Income Taxes or any Pass-Through Return (a “Tax Contest”) with respect to a Straddle Period, Altimar will, within 15 days of it (or any of its Subsidiaries) being notified of such Tax Contest, notify the Unitholder Representative of such Tax Contest in writing. All Tax Contests for any taxable periods initiated or continuing after the Closing Date shall be controlled in accordance with the terms of the Fathom Operating Agreement.

(h) After the Closing, Altimar (and its Subsidiaries) will not, without the consent of the Unitholder Representative (which consent will not be unreasonably withheld, conditioned or delayed), (I) amend or otherwise modify any Pass-Through Return, (II) extend or waive, or cause to be extended or waived, any statute of limitations or other period for the assessment of any Pass-Through Income Taxes for Pre-Closing Tax Periods (other than the portion of any Straddle Period ending on the Closing Date) or audit of any Pass-Through Return, or (III) make or change any income election or accounting method or practice with respect to Pass-Through Income Taxes for Pre-Closing Tax Periods (other than the portion of any Straddle Period ending on the Closing Date) or Pass-Through Returns.

(i) Within 90 days following the Closing Date, (i) Altimar will prepare, and deliver to the Unitholder Representative, an allocation statement allocating the applicable portion of the Closing Cash Consideration and any other amounts treated as consideration for U.S. federal income Tax purposes in the Cash Sale among the direct and indirect assets of Fathom (and entities disregarded as separate from Fathom) in accordance with Section 1060 of the Code (and any other applicable section of the Code), the Treasury Regulations thereunder (and any similar provision of state or local Law) and the methodologies set forth on Schedule 10.04(i) (the “Allocation”). The Allocation shall contain sufficient detail to permit the Parties to make the computations and adjustments required under Sections 743(b), 751 and 755 of the Code and the Treasury Regulations thereunder. Within 45 days after the receipt of the Allocation, the Unitholder Representative will propose any changes, and the Unitholder Representative and Altimar shall cooperate in good faith to resolve any disagreements. If Altimar and the Unitholder Representative do not, within 14 days, resolve all disagreements, each disagreement shall be submitted to a mutually acceptable nationally recognized independent accounting firm (acting as expert, not as arbitrator), which shall resolve such disagreements as soon as reasonably practicable; provided that such accounting firm utilizes the methodologies for determining fair market value as set forth on Schedule 10.04(i). The determination(s) of such accounting firm shall be final and binding. The fees of such accounting firm shall be borne equally by the Unitholder Representative and Altimar. The Allocation, as mutually agreed or as finally determined by such accounting firm, shall be final and binding.

(j) Each Party and the Unitholder Representative shall reasonably cooperate (and cause its Affiliates to reasonably cooperate), as and to the extent reasonably requested by each other Party and the Unitholder Representative, in connection with the preparation and filing of Tax Returns or any Tax Contest. Such cooperation shall include the provision of available records and information that are reasonably relevant to any such matter and making employees available on a mutually convenient basis to provide additional information and explanation with respect thereto.

(k) Following the Blocker Altimar Mergers, and prior to the Fathom Merger, Altimar may, but shall not be required to, cause CL Buyer Corp., a Delaware corporation, and Summit Tooling Holding, Inc., a Delaware corporation, to merge with and into the Altimar Surviving Entity (the “Subsidiary Mergers”), with the Altimar Surviving Entity being the surviving entity of the Subsidiary Mergers.

In the event an individual designated in accordance with Section 10.07(a) does not satisfy any requirement of a Governmental Authority or the NYSE to serve as a director, then (x) there shall be no obligation to appoint such individual pursuant to Section 10.07(a) and (y) Fathom shall be entitled to designate a replacement director in lieu of such person, which replacement director shall be designated in consultation with Altimar; provided, further, that in no event shall Closing be delayed or postponed in connection with or as a result of the foregoing.

Fathom shall have the option to elect to repay, refinance or obtain any Debt Financing up to an aggregate principal amount of $175,000,000, in each case which election shall be made in consultation with Altimar. To the extent Fathom determines, in consultation with Altimar, to obtain any Debt Financing, Fathom shall, and shall cause its Subsidiaries to, use its reasonable best efforts to do all things necessary or appropriate to arrange for and obtain such Debt Financing, including using reasonable best efforts to (i) negotiate, syndicate and enter into definitive agreements with respect to such Debt Financing, (ii) satisfy on a timely basis all terms, conditions and covenants that may be required in connection with such Debt Financing, including with respect to the payment of any commitment, engagement or placement fees, and (iii) otherwise consummate and cause such Debt Financing to be funded at or prior the Closing; provided, that, (x) Fathom shall reasonably consult with Altimar in respect of the foregoing and consider in good faith any comments provided by Altimar in respect thereof and (y) Altimar and its Representatives shall reasonably cooperate in connection therewith.

Notwithstanding anything to the contrary set forth herein, in no event will Fathom be in breach of any of its obligations under this Agreement, including with respect to its covenants set forth in this Section 10.08, due solely to any failure of any amount to be funded in accordance with the PIPE Investment when otherwise required in accordance with the terms of thereof, or to the extent related to the amount of the Available Cash Amount, in each case in and of itself and without any other breach by Fathom that is a proximate cause of such failure of such amount to be funded in accordance with the PIPE Investment.

Section 13.06 Governing Law. This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of Laws of another jurisdiction.

All references herein to Schedules and Exhibits shall be deemed references to such parts of this Agreement, unless the context shall otherwise require. Any disclosure made by a Party in the Schedules with reference to any section or schedule of this Agreement shall be deemed to be a disclosure with respect to all other sections or schedules to which such disclosure may apply solely to the extent the relevance of such disclosure is reasonably apparent on the face of the disclosure in such Schedule.

Section 13.09 Entire Agreement. This Agreement (together with the Schedules and Exhibits to this Agreement), the other Transaction Agreements and that certain letter agreement, dated as of May 23, 2021, by and between Fathom and Altimar (as amended, modified or supplemented from time to time, the “Confidentiality Agreement”), constitute the entire agreement among the Parties relating to the transactions contemplated hereby and supersede any other agreements, whether written or oral, that may have been made or entered into by or among any of the Parties or any of their respective Subsidiaries relating to the transactions contemplated hereby, including this Agreement. No representations, warranties, covenants, understandings, agreements, oral or otherwise, relating to the transactions contemplated by this Agreement exist between the Parties except as expressly set forth or referenced in this Agreement, the other Transaction Agreements and the Confidentiality Agreement.

C-94

Section 13.10 Amendments. This Agreement may be amended or modified in whole or in part, only by a duly authorized agreement in writing executed in the same manner as this Agreement and which makes reference to this Agreement. The approval of this Agreement by the members or equityholders of any of the Parties shall not restrict the ability of the board of directors (or other body or entity performing similar functions) of any of the Parties to terminate this Agreement in accordance with Section 12.01 or, subject to applicable Law, including the DGCL and the Cayman Islands Companies Act (2021 Revision), to cause such Party to enter into an amendment to this Agreement pursuant to this Section 13.10.

Section 13.11 Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The Parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the Parties.

Section 13.12 Jurisdiction; WAIVER OF TRIAL BY JURY. Any Action based upon, arising out of or related to this Agreement or the transactions contemplated hereby may be brought in federal and state courts located in the State of Delaware, and each of the Parties irrevocably submits to the exclusive jurisdiction of each such court in any such Action, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Action shall be heard and determined only in any such court, and agrees not to bring any Action arising out of or relating to this Agreement or the transactions contemplated hereby in any other court. Nothing herein contained shall be deemed to affect the right of any Party to serve process in any manner permitted by Law or to commence legal proceedings or otherwise proceed against any other Party in any other jurisdiction, in each case, to enforce judgments obtained in any Action brought pursuant to this Section 13.12. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Section 13.13 Enforcement. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate this Agreement) or any Transaction Agreement in accordance with its specified terms or otherwise breach such provisions. The Parties acknowledge and agree that (i) the Parties shall be entitled to an injunction, specific performance, or other equitable relief, to prevent breaches of this Agreement or any Transaction Agreement and to enforce specifically the terms and provisions hereof and thereof, without proof of damages, prior to the valid termination of this Agreement in accordance with Section 12.01, this being in addition to any other remedy to which they are entitled under this Agreement or any Transaction Agreement, and (ii) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, none of the Parties would have entered into this Agreement. Each Party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other Parties have an adequate remedy at Law or that an award of specific performance is not an appropriate remedy for any reason at Law or equity. The Parties acknowledge and agree that any Party seeking an injunction to prevent breaches of this Agreement or any Transaction Agreement and to enforce specifically the terms and provisions of this Agreement or any Transaction Agreement in accordance with this Section 13.13 shall not be required to provide any bond or other security in connection with any such injunction. Without limiting the generality of the foregoing, Altimar acknowledges and agrees that Fathom may, without breach of this Agreement, with respect to any Transaction Agreement to which Fathom is a party, institute or pursue an Action directly against the counterparty(ies) to such Transaction Agreement seeking, or seek or obtain a court order against the counterparty(ies) to such Transaction Agreement for, injunctive relief, specific performance, or other equitable relief with respect to such Transaction Agreement.

C-95

Section 13.14 Non-Recourse. Subject in all respects to the last sentence of this Section 13.14, this Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly named as Parties and then only with respect to the specific obligations set forth herein with respect to such Party. Except to the extent a Party hereto (and then only to the extent of the specific obligations undertaken by such Party in this Agreement), (a) no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney, advisor or representative or Affiliate of any Party and (b) no past, present or future director, officer, employee, incorporator, member, partner, stockholder, Affiliate, agent, attorney, advisor or representative or Affiliate of any of the foregoing shall have any Liability (whether in contract, tort, equity or otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of any one or more of Fathom, the Fathom Blockers or the Altimar Parties under this Agreement of or for any claim based on, arising out of, or related to this Agreement or the transactions contemplated hereby. Notwithstanding the foregoing, nothing in this Section 13.14 shall limit, amend or waive any rights of any party to any Transaction Agreement under such Transaction Agreement; provided such rights can only be enforced against the actual parties to the applicable Transaction Agreements in accordance with the terms thereof.

Section 13.15 Nonsurvival of Representations, Warranties and Covenants. None of the representations, warranties, covenants, obligations or other agreements in this Agreement or in any certificate, statement or instrument delivered pursuant to this Agreement, including any rights arising out of any breach of such representations, warranties, covenants, obligations, agreements and other provisions, shall survive the Closing and instead shall terminate and expire upon the occurrence of the Closing (and there shall be no liability after the Closing in respect thereof), except for (a) those covenants and agreements contained herein that by their terms expressly apply in whole or in part at or after the Closing and then only with respect to any breaches occurring at or after the Closing (including, for the avoidance of doubt Section 10.05(b)) and (b) this Article XIII.

Section 13.16 Acknowledgements.

(a) Each of the Parties acknowledges and agrees (on its own behalf and on behalf of its respective Affiliates and its and their respective Representatives) that: (i) it has conducted its own independent investigation of the financial condition, results of operations, assets, liabilities, properties and projected operations of the other Parties (and their respective Subsidiaries) and has been afforded satisfactory access to the books and records, facilities and personnel of the other Parties (and their respective Subsidiaries) for purposes of conducting such investigation; (ii) the Fathom Representations constitute the sole and exclusive representations and warranties of Fathom; (iii) the Altimar Representations constitute the sole and exclusive representations and warranties of Altimar; (iv) the Fathom Blocker Representations constitute the sole and exclusive representations and warranties of the Fathom Blockers; (v) except for the Fathom Representations by Fathom, the Altimar Representations by the Altimar Parties and the Fathom Blocker Representations by the Fathom Blockers, none of the Parties or any other Person makes, or has made, any other express or implied representation or warranty with respect to any Party (or any Party’s Subsidiaries), including any implied warranty or representation as to condition, merchantability, suitability or fitness for a particular purpose or trade as to any of the assets of the such Party or its Subsidiaries or the transactions contemplated by this Agreement and all other representations and warranties of any kind or nature expressed or implied (including any relating to the future business, condition (financial or otherwise), results of operations, prospects, assets or liabilities of any Party (or its Subsidiaries)) are specifically disclaimed by all Parties and their respective Subsidiaries and all other Persons (including the Representatives and Affiliates of any Party or its Subsidiaries); and (vi) each Party and its respective Affiliates have not relied and are not relying on any representations and warranties (or the omission of any representations) in connection with the Transactions except the Fathom Representations by Fathom, the Altimar Representations by the Altimar Parties and the Fathom Blocker Representations by the Fathom Blockers, and the certifications pursuant to Section 11.02(d) or Section 11.03(d). The foregoing does not limit any rights of any Party pursuant to any other Transaction Agreement against any other Party pursuant to such Transaction Agreement to which it is a party or an express third party beneficiary thereof.

C-96

(b) Effective upon Closing, each of the Parties waives, on its own behalf and on behalf of its respective Affiliates and Representatives, to the fullest extent permitted under applicable Law, any and all rights, Actions and causes of action it may have against any other Party or their respective Subsidiaries and any of their respective current or former Affiliates or Representatives relating to the operation of any Party or its Subsidiaries or their respective businesses or relating to the subject matter of this Agreement, the Schedules, or the Exhibits to this Agreement, whether arising under or based upon any federal, state, local or foreign statute, Law, ordinance, rule or regulation or otherwise. Each Party acknowledges and agrees that it will not assert, institute or maintain any Action, suit, investigation, or proceeding of any kind whatsoever, including a counterclaim, cross-claim, or defense, regardless of the legal or equitable theory under which such liability or obligation may be sought to be imposed, that makes any claim contrary to the agreements and covenants set forth in this Section 13.16. Notwithstanding anything herein to the contrary, nothing in this Section 13.16(b) shall preclude any Party from seeking any remedy for Fraud by a Party with respect to the making of the representations and warranties pursuant to Article V, Article VI or Article VII (as applicable). Each Party shall have the right to enforce this Section 13.16 on behalf of any Person that would be benefitted or protected by this Section 13.16 if they were a party hereto. The foregoing agreements, acknowledgements, disclaimers and waivers are irrevocable. For the avoidance of doubt, nothing in this Section 13.16 shall limit, modify, restrict or operate as a waiver with respect to, any rights any Party may have under any written agreement entered into in connection with the transactions that are contemplated by this Agreement, including any other Transaction Agreement.

EXHIBIT A

FINAL FORM

CERTIFICATE OF INCORPORATION

OF

FATHOM DIGITAL MANUFACTURING CORPORATION

Fathom Digital Manufacturing Corporation, a corporation organized and existing under the laws of the State of Delaware, does hereby certify as follows:

ARTICLE ONE

The name of the corporation is Fathom Digital Manufacturing Corporation (the “Corporation”).

ARTICLE TWO

The address of the Corporation’s registered office in the State of Delaware is 1209 Orange Street, in the City of Wilmington, County of New Castle, Delaware, 19801. The name of its registered agent at such address is The Corporation Trust Company.

ARTICLE THREE

The nature and purpose of the business of the Corporation is to engage in any lawful act or activity for which corporations may be organized under the General Corporation Law of the State of Delaware (the “DGCL”). The Corporation is being incorporated in connection with the domestication of Altimar Acquisition Corp. II, a Cayman Islands exempted company (“Altimar Cayman”), as a Delaware corporation (the “Domestication”), and this Certificate of Incorporation (as hereinafter defined) and the Certificate of Corporate Domestication of Altimar Cayman are being filed simultaneously with the Secretary of State of the State of Delaware.

ARTICLE FOUR

Section 1. Authorized Shares. The total number of shares of all classes of capital stock which the Corporation shall have authority to issue is [●] shares, consisting of three classes as follows:

1. 50,000,000 shares of Preferred Stock, par value $0.0001 per share (the “Preferred Stock”);

2. [●] shares of Class A Common Stock, par value $0.0001 per share (the “Class A Common Stock”);

3. [●] shares of Class B Common Stock, par value $0.0001 per share (the “Class B Common Stock”); and

4. [●] shares of Class C Common Stock, par value $0.0001 per share (the “Class C Common Stock” and, together with the Class A Common Stock and Class B Common Stock, the “Common Stock”).

Upon the effectiveness of the Domestication and this Certificate of Incorporation (A) each Class A ordinary share, par value $0.0001 per share (a “Class A Cayman Share”), of Altimar Cayman that is outstanding immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation will, for all purposes, be deemed to be one issued and outstanding, fully paid and non-assessable share of Class A Common Stock, without any action required on the part of the Corporation or the holders thereof, (B) each Class B

C-103

ordinary share, par value $0.0001 per share (a “Class B Cayman Share”), of Altimar Cayman that is outstanding immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation will, for all purposes, be deemed to be one issued and outstanding, fully paid and non-assessable share of Class C Common Stock, without any action required on the part of the Corporation or the holders thereof, and (C) any stock certificate that, immediately prior to the effectiveness of the Domestication and this Certificate of Incorporation, represented Class A Cayman Shares or Class B Cayman Shares will, from and after the effectiveness of the Domestication and this Certificate of Incorporation, automatically and without the necessity of presenting the same for exchange, represent an identical number of shares of Class A Common Stock or Class C Common Stock (respectively) of the Corporation, as applicable. Notwithstanding anything to the contrary herein, following the filing and effectiveness of this Certificate of Incorporation with the Secretary of State of the State of Delaware, the Corporation shall not issue additional shares of Class C Common Stock.

The Preferred Stock and the Common Stock shall have the designations, rights, powers and preferences and the qualifications, restrictions and limitations thereof, if any, set forth below. The number of authorized shares of Class A Common Stock, Class B Common Stock, Class C Common Stock or Preferred Stock may be increased or decreased (but not below the number of shares thereof then outstanding) by the approval of the Board of Directors of the Corporation (the “Board of Directors”) and by the affirmative vote of the holders of a majority in voting power of the then-outstanding shares of capital stock of the Corporation entitled to vote generally in an election of directors, and no vote of the holders of any of Class A Common Stock, Class B Common Stock, Class C Common Stock or Preferred Stock voting separately as a class shall be required therefor, regardless of the provisions of Section 242(b)(2) of the DGCL (or any successor provisions thereto). No stockholder shall, by reason of the holding of shares of any class or series of capital stock of the Corporation, have any preemptive or preferential right to acquire or subscribe for any shares or securities of any class or series, whether now or hereafter authorized, which may at any time be issued, sold or offered for sale by the Corporation, unless specifically provided for in a Preferred Stock Designation (as hereinafter defined). The Corporation has the authority to create and issue rights, warrants and options entitling the holders thereof to acquire from the Corporation any shares of its capital stock of any class or classes, with such rights, warrants and options to be evidenced by or in instrument(s) approved by the Board of Directors. The Board of Directors is empowered to set the exercise price, duration, times for exercise and other terms and conditions of such rights, warrants or options. Notwithstanding the foregoing, the consideration to be received for any shares of capital stock issuable upon exercise thereof may not be less than the par value thereof. The Corporation shall at all times reserve and keep available out of its authorized but unissued shares of capital stock a number of shares of the class of capital stock issuable pursuant to any such rights, warrants and options outstanding from time to time.

Section 2. Preferred Stock. The Board of Directors is authorized, subject to limitations prescribed by law, to provide, by resolution or resolutions for the issuance of shares of Preferred Stock in one or more series, and with respect to each series, to establish the number of shares to be included in each such series, and to fix the voting powers (if any), designations, powers, preferences, and relative, participating, optional or other special rights, if any, of the shares of each such series, and any qualifications, restrictions or limitations thereof, as are stated and expressed herein and in the resolution or resolutions providing for the issue of such class or series adopted by the Board of Directors and included in a certificate or certificates of designation (each, a “Preferred Stock Designation”). The powers (including voting powers), preferences, and relative, participating, optional and other special rights of each series of Preferred Stock and the qualifications, restrictions or limitations thereof, if any, may differ from those of any and all other series at any time outstanding. Except as otherwise required by law, holders of a series of Preferred Stock, as such, shall be entitled only to such voting rights, if any, as shall expressly be granted thereto by this Certificate of Incorporation (including any Preferred Stock Designation relating to such series).

Section 3. Common Stock.

(a) Except as otherwise provided by the DGCL or this Certificate of Incorporation (as it may be amended, the “Certificate of Incorporation”), and subject to the rights of holders of any series of Preferred Stock, all of the

C-104

voting power of the stockholders of the Corporation shall be vested in the holders of the Common Stock. Each share of Common Stock shall entitle the holder thereof to one vote for each share held by such holder on all matters voted upon by the stockholders of the Corporation; provided, however, that, except as otherwise required by law, holders of Common Stock, as such, shall not be entitled to vote on any amendment to this Certificate of Incorporation (including any Preferred Stock Designation relating to any series of Preferred Stock) that relates solely to the terms of one or more outstanding series of Preferred Stock if the holders of such affected series are entitled, either separately or together with the holders of one or more other such series, to vote thereon pursuant to this Certificate of Incorporation (including any Preferred Stock Designation relating to any series of Preferred Stock) or pursuant to the DGCL.

(b) Except as otherwise required by law or expressly provided in this Certificate of Incorporation, each share of Common Stock shall have the same powers, rights and privileges and shall rank equally, share ratably and be identical in all respects as to all matters.

(c) Subject to the rights of the holders of Preferred Stock and to the other provisions of applicable law and this Certificate of Incorporation, the holders of shares of Class A Common Stock and, solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction, holders of Class C Common Stock, in each case shall be entitled to receive ratably in proportion to the number of shares of Class A Common Stock and Class C Common Stock (as applicable) held by them such dividends and distributions (payable in cash, stock or otherwise), if any, as may be declared thereon by the Board of Directors at any time and from time to time out of any funds of the Corporation legally available therefor. There will be no disparate consideration or treatment with respect to dividends and distributions, if any, declared or payable in respect of each share of the Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction), on the one hand, and a Class A Unit (as defined in the LLC Agreement (as hereinafter defined)), on the other hand. Dividends and other distributions shall not be declared or paid on the Class B Common Stock unless (i) the dividend consists of shares of Class B Common Stock or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class B Common Stock paid proportionally with respect to each outstanding share of Class B Common Stock and (ii) a dividend consisting of shares of Class A Common Stock, Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) or of rights, options, warrants or other securities convertible or exercisable into or exchangeable for shares of Class A Common Stock (to the extent a similar or contemptuous dividend or distribution is not paid on the Class A Units) or Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) on equivalent terms is simultaneously paid to the holders of Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction). If dividends are declared on the Class A Common Stock, the Class B Common Stock or the Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) that are payable in shares of Common Stock, or securities convertible into, or exercisable or exchangeable for Common Stock, the dividends payable to the holders of Class A Common Stock shall be paid only in shares of Class A Common Stock (or securities convertible into, or exercisable or exchangeable for Class A Common Stock), the dividends payable to the holders of Class B Common Stock shall be paid only in shares of Class B Common Stock (or securities convertible into, or exercisable or exchangeable for Class B Common Stock), the dividends payable to the holders of Class C Common Stock shall be paid only in shares of Class C Common Stock (or securities convertible into, or exercisable or exchangeable for Class C Common Stock), and such dividends shall be paid in the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock, Class B Common Stock and Class C Common Stock, respectively (or securities convertible into, or exercisable or exchangeable for the same number of shares (or fraction thereof) on a per share basis of the Class A Common Stock, Class B Common Stock and Class C Common Stock, respectively). For purposes of this Certificate of Incorporation, “BCA Transaction” means the business combination transactions contemplated by that certain Business Combination Agreement, dated as of July [    ], 2021, by and among the Corporation, Fathom Holdco, LLC and other Persons party thereto, as the same may be amended, restated, supplemented or waived from time to time (the “BCA”).

C-105

(d) In the event of any voluntary or involuntary liquidation, dissolution or winding-up of the Corporation, after distribution in full of the preferential amounts, if any, to be distributed to the holders of shares of Preferred Stock or any series thereof, the holders of shares of Class A Common Stock and Class C Common Stock (solely prior to the automatic conversion thereof upon and as a result of the BCA Transaction) shall be entitled to receive all of the remaining assets of the Corporation available for distribution to its stockholders, ratably in proportion to the number of shares of Class A Common Stock and Class C Common Stock (as applicable) held by them. The holders of shares of Class B Common Stock, as such, shall not be entitled to receive any assets of the Corporation in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of the Corporation. A dissolution, liquidation or winding-up of the Corporation, as such terms are used in this paragraph (d), shall not be deemed to be occasioned by or to include any consolidation or merger of the Corporation with or into any other corporation or corporations or other entity or a sale, lease, exchange or conveyance of all or a part of the assets of the Corporation; provided, that notwithstanding anything to the contrary herein, in the event of any such merger, sale, lease, exchange or conveyance, or any other similar transaction or recapitalization, the holders of shares of Class B Common Stock shall not be entitled to any consideration in connection therewith other than the right to receive securities with equivalent terms and conditions as the Class B Common Stock, and the consideration payable in respect of a share of Class A Common Stock shall equal the consideration payable in respect of a Class A Unit.

(e) Shares of Class B Common Stock shall be redeemable for shares of Class A Common Stock on the terms and subject to the conditions set forth in the Second Amended and Restated Limited Liability Company Agreement of Fathom Holdco, LLC, dated as of [                    ], 2021, as it may be amended from time to time in accordance with its terms (the “LLC Agreement”). The Corporation will at all times reserve and keep available out of its authorized but unissued shares of Class A Common Stock, solely for the purpose of issuance upon redemption of the outstanding shares of Class B Common Stock for Class A Common Stock pursuant to the LLC Agreement, such number of shares of Class A Common Stock that shall be issuable upon any such redemption pursuant to the LLC Agreement; provided that nothing contained herein shall be construed to preclude the Corporation from satisfying its or its affiliates’ obligations in respect of any such redemption of shares of Class B Common Stock pursuant to the LLC Agreement by delivering (either directly or indirectly through an affiliate) to the holder of shares of Class B Common Stock upon such redemption, in lieu of newly issued shares of Class A Common Stock, cash in the amount permitted by and provided in the LLC Agreement or shares of Class A Common Stock which are held in the treasury of the Corporation. All shares of Class A Common Stock that may be issued upon any such redemption shall, upon issuance in accordance with the LLC Agreement, be validly issued, fully paid and non-assessable. All shares of Class B Common Stock redeemed shall not be disposed of out of treasury or otherwise reissued and shall be cancelled.

(f) Conversion of Class C Common Stock.

(i) Shares of Class C Common Stock shall automatically convert into shares of Class A Common Stock on a one-for-one basis (the “Initial Conversion Ratio”): (A) at any time and from time to time at the option of the holder thereof; or (B) automatically and without further action by the Corporation or the holder thereof on the day of the closing of a Business Combination, which for the avoidance of doubt will be the closing of the BCA Transaction.

(ii) Notwithstanding the Initial Conversion Ratio, in the case that additional shares of Class A Common Stock or any other Equity-linked Securities (as hereinafter defined), are issued or deemed issued in excess of the amounts offered in the IPO and related to the closing of a Business Combination, all outstanding shares of Class C Common Stock shall automatically convert into shares of Class A Common Stock at the time of the closing of a Business Combination at such ratio (unless the holders of a majority of the outstanding shares of Class C Common Stock agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) that results in the number of shares of Class A Common Stock issuable upon conversion of all outstanding shares of Class C Common Stock be equal to, in the aggregate, 20% of the sum of all shares of Class A Common Stock and Class C Common Stock outstanding upon completion of the IPO plus all shares of

C-106

Class A Common Stock and Equity-linked Securities issued or deemed issued in connection with a Business Combination, excluding any shares or Equity-linked Securities issued, or to be issued, to any seller in an initial Business Combination.

(iii) Notwithstanding anything to the contrary contained herein, the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional shares of Class A Common Stock or Equity-linked Securities by the written consent or agreement of holders of a majority of the outstanding shares of Class C Common Stock consenting or agreeing separately as a separate class.

(iv) The foregoing conversion ratio shall also be adjusted to account for any subdivision (by share split, subdivision, exchange, capitalization, rights issue, reclassification, recapitalization or otherwise) or combination (by reverse share split, share consolidation, exchange, reclassification, recapitalization or otherwise) or similar reclassification or recapitalizations of the outstanding shares of Class A Common Stock into a greater or lesser number of shares occurring after the Effective Date without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalization of the outstanding shares of Class C Common Stock.

(v) Each share of Class C Common Stock shall convert into its pro rata number of shares of Class A Common Stock pursuant to this Section 3(f). The pro rata share for each holder of shares of Class C Common Stock will be determined as follows: each share of Class C Common Stock shall convert into such number of shares of Class A Common Stock as is equal to the product of one multiplied by a fraction, the numerator of which shall be the total number of shares of Class C Common Stock into which all of the outstanding shares of Class C Common Stock in issue shall be converted pursuant to this Section 3(f) and the denominator of which shall be the total number of outstanding shares of Class C Common Stock at the time of conversion.

(vi) Notwithstanding anything to the contrary in this Section 3(f), in no event may any share of Class C Common Stock convert into shares of Class A Common Stock at a ratio that is less than one-for-one

(vii) As used in this Section 3(f):

(A) “converted”, “conversion” or “exchange” shall have its ordinary meaning under Delaware law, and thereby shall have the same effect as a compulsory redemption without notice of shares of Class C Common Stock of any stockholder and, on behalf of such stockholders, automatic application of such redemption proceeds in paying for such new shares of Class A Common Stock into which the shares of Class C Common Stock have been converted or exchanged at a price per share of Class C Common Stock necessary to give effect to a conversion or exchange calculated on the basis that the shares of Class A Common Stock to be issued as part of the conversion or exchange will be issued at par. The shares of Class A Common Stock to be issued on an exchange or conversion shall be registered in the name of such stockholder or in such name as the stockholder may direct;

(B) “Equity-linked Securities” means any debt or equity securities that are convertible, exercisable or exchangeable for shares of Class A Common Stock issued in a financing transaction in connection with a Business Combination, including, but not limited to, a private placement of equity or debt; and

(C) “IPO” means the initial public offering of Altimar Cayman.

(viii) Shares of Class C Common Stock converted into shares of Class A Common Stock pursuant to Section 3(f) shall be cancelled by the Corporation and may not be reissued. At any time after consummation of a Business Combination, when there are no longer any shares of Class C Common Stock outstanding, the Corporation shall take all necessary action to retire and eliminate the Class C Common Stock, and shall amend this Certificate of Incorporation to eliminate references thereto.

(xi) Nothing in Section 3(f) of this Certificate of Incorporation shall limit or amend any obligation or agreement of any party to the Sponsor Agreement. To the extent of any conflict or inconsistency between the terms and

C-107

provisions of the Sponsor Agreement and the terms and provisions of this Certificate of Incorporation, including (without limitation) Section 3(f) hereof, the terms and provisions of the Sponsor Agreement shall control. For purposes of this Certificate of Incorporation, “Sponsor Agreement” means that certain Sponsor Agreement referred to in the BCA pursuant to which, among other things, the Sponsor Persons (as defined in the BCA) have agreed to (i) vote in favor of, and take all actions necessary to consummate, the BCA Transactions, (ii) the lock-up period and conditions described therein, (iii) following the consummation of the Mergers (as defined in the BCA), a certain amount of their Class A Common Stock will be subject to vesting restrictions described therein, (iv) as holder of a majority of the Class B Cayman Shares prior to the Domestication and a majority of the shares of Class C Common Stock at the filing of this Certificate of Incorporation with the Secretary of State of the State of Delaware to waive certain anti-dilution adjustments set forth in Section 17.3 of Altimar Cayman’s Memorandum and Articles of Association and Section 3(f) of this Certificate of Incorporation in connection with the transactions contemplated by the BCA and (y) to forfeit certain shares of Class A Common Stock received upon the automatic conversion of its shares of Class C Common Stock upon the closing of the transactions contemplated by the BCA for no consideration; and (v) to the conversion of Class C Common Stock into Class A Common Stock automatically upon consummation the BCA Transaction.

(g) No Transfer of any shares of Common Stock or shares of Preferred Stock may be made, except in compliance with the Investor Rights Agreement (as hereinafter defined) or Sponsor Agreement (if and as applicable) and applicable federal and state securities laws. No Transfer of shares of Class B Common Stock may be made, unless such transferor also Transfers an equal number of applicable Class A Units to the applicable transferee in accordance with the terms and conditions of the LLC Agreement. The Corporation may place customary restrictive legends on the certificates or book entries representing the shares of Common Stock and, if applicable, the shares of Preferred Stock subject to this Section 3(g) and remove such restrictive legends at the time the applicable restrictions under this Section 3(g) are no longer applicable to the shares of Common Stock or shares of Preferred Stock represented by such certificates or book entries. To the extent shares of Common Stock and, if applicable, shares of Preferred Stock subject to this Section 3(g) are uncertificated, the Corporation shall give notice of the restrictions set forth in this Section 3(g) in accordance with the DGCL. For purposes of this Certificate of Incorporation, “Transfer” has the meaning set forth in the Investor Rights Agreement or Sponsor Agreement, as applicable.

During any period when the holders of any series of Preferred Stock, voting separately as a series or together with one or more series, have the right to elect additional directors, then upon commencement and for the duration of the period during which such right continues: (i) the then otherwise total authorized number of directors of the Corporation shall automatically be increased by such specified number of directors, and the holders of such Preferred Stock shall be entitled to elect the additional directors so provided for or fixed pursuant to said provisions, and (ii) each such additional director shall serve until such director’s successor shall have been duly elected and qualified, or until such director’s right to hold such office terminates pursuant to said provisions, whichever occurs earlier, subject to his or her earlier death, resignation, disqualification or removal.

Section 1. Certain Acknowledgments. In recognition and anticipation that (i) certain of the directors, partners, principals, officers, members, managers and/or employees of CORE Industrial Partners, LLC (“CORE”) or its Affiliated Companies (as hereinafter defined) may serve as directors or officers of the Corporation and (ii) CORE and its Affiliated Companies engage and may continue to engage in the same or similar activities or related lines of business as those in which the Corporation, directly or indirectly, may engage and/or other business activities that overlap with or compete with those in which the Corporation, directly or indirectly, may engage, and (iii) that the Corporation and its Affiliated Companies may engage in material business transactions with CORE and its Affiliated Companies, and that the Corporation is expected to benefit therefrom, the provisions of this ARTICLE EIGHT are set forth to regulate and define to the fullest extent permitted by law the conduct of certain affairs of the Corporation as they may involve CORE and/or its Affiliated Companies and/or their respective directors, partners, principals, officers, members, managers and/or employees, including any of the foregoing who serve as officers or directors of the Corporation (collectively, the “Exempted Persons”), and the powers, rights, duties and liabilities of the Corporation and its officers, directors and stockholders in connection therewith.

To the fullest extent permitted by applicable law, the Corporation, on behalf of itself and its Affiliated Companies, renounces any interest or expectancy of the Corporation and its Affiliated Companies in, or in being offered an opportunity to participate in, business opportunities that are from time to time presented to the Exempted Persons, even if the opportunity is one that the Corporation or its Affiliated Companies might reasonably be deemed to have pursued or had the ability or desire to pursue if granted the opportunity to do so, and each Exempted Person shall have no duty to communicate or offer such business opportunity to the Corporation or its Affiliated Companies and, to the fullest extent permitted by applicable law, shall not be liable to the Corporation, any of its Affiliated Companies or its stockholders for breach of any fiduciary or other duty, as a director, officer or stockholder of the Corporation solely, by reason of the fact that CORE, its Affiliated Companies or any such Exempted Person pursues or acquires such business opportunity, sells, assigns, transfers or directs such business opportunity to another person or fails to present such business opportunity, or information regarding such business opportunity, to the Corporation or any of its Affiliated Companies. Notwithstanding anything to the contrary in this Section 2, the Corporation does not renounce any interest or expectancy it may have in any business opportunity that is expressly offered to any Exempted Person solely in his or her capacity as a director or officer of, or through his or her service to, or pursuant to a contract with, the Corporation, and not in any other capacity. Nothing in this Certificate of Incorporation shall be deemed to supersede any other agreement to which an Exempted Person may be a party or the rights of any other party thereto restricting such Exempted Person’s ability to have certain business interests or engage in certain business activities or ventures.

Section 3. Certain Matters Deemed Not Corporate Opportunities. In addition to and notwithstanding the foregoing provisions of this ARTICLE EIGHT, a corporate opportunity shall not be deemed to belong to the Corporation if it is a business opportunity the Corporation is not financially able or contractually permitted or legally able to undertake, or that is, from its nature, not in the line of the Corporation’s business or is of no practical advantage to it or that is one in which the Corporation has no interest or reasonable expectancy.

Section 251(g) of the DGCL; (C) pursuant to a dividend or distribution paid or made, or the exercise, exchange or conversion of securities exercisable for, exchangeable for or convertible into Stock of the Corporation or any such subsidiary which security is distributed, pro rata to all holders of a class or series of Stock of the Corporation subsequent to the time the Interested Stockholder became such; (D) pursuant to an exchange offer by the Corporation to purchase Stock made on the same terms to all holders of such Stock; or (E) any issuance or transfer of Stock by the Corporation; provided however, that in no case under items (C)-(E) of this Section 4(c)(iii) of ARTICLE NINE shall there be an increase in the Interested Stockholder’s proportionate share of the Stock of any class or series of the Corporation or of the Voting Stock of the Corporation;

(iv) any transaction involving the Corporation or any direct or indirect majority-owned subsidiary of the Corporation which has the effect, directly or indirectly, of increasing the proportionate share of the Stock of any class or series, or securities convertible into the Stock of any class or series, of the Corporation or of any such subsidiary which is owned by the Interested Stockholder, except as a result of immaterial changes due to fractional share adjustments or as a result of any purchase or redemption of any shares of Stock not caused, directly or indirectly, by the Interested Stockholder; or

(v) any receipt by the Interested Stockholder of the benefit, directly or indirectly (except proportionately as a stockholder of the Corporation), of any loans, advances, guarantees, pledges or other financial benefits (other than those expressly permitted in Sections 4(c)(i)-(iv) of ARTICLE NINE) provided by or through the Corporation or any direct or indirect majority-owned subsidiary of the Corporation;

(d) “Control,” including the terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a Person, whether through the ownership of Voting Stock, by contract or otherwise. A Person who is the owner of twenty percent (20%) or more of the outstanding Voting Stock of any corporation, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary; notwithstanding the foregoing, a presumption of control shall not apply where such Person holds Voting Stock, in good faith and not for the purpose of circumventing this ARTICLE NINE, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group (as such term is used in Rule 13d-5 under the Exchange Act, as such Rule is in effect as of the date of this Certificate of Incorporation) have control of such entity;

(e) “Interested Stockholder” means any Person (other than the Corporation and any direct or indirect majority-owned subsidiary of the Corporation) that (i) is the owner of fifteen percent (15%) or more of the outstanding Voting Stock of the Corporation, or (ii) is an Affiliate or Associate of the Corporation and was the owner of fifteen percent (15%) or more of the outstanding Voting Stock of the Corporation at any time within the three-year period immediately prior to the date on which it is sought to be determined whether such Person is an Interested Stockholder, and the Affiliates and Associates of such Person. Notwithstanding anything in this ARTICLE NINE to the contrary, the term “Interested Stockholder” shall not include: (x) CORE or any of its Affiliated Companies, or any other Person with whom any of the foregoing are acting as a group or in concert for the purpose of acquiring, holding, voting or disposing of shares of Stock of the Corporation, in each case so long as such Persons beneficially own at least fifteen percent (15%) or more of the outstanding Voting Stock of the Corporation, (y) any Person who would otherwise be an Interested Stockholder either in connection with or because of a transfer, sale, assignment, conveyance, hypothecation, encumbrance, or other disposition of five percent (5%) or more of the outstanding Voting Stock of the Corporation (in one transaction or a series of transactions) by CORE or any of its Affiliates or Associates of such Person (for so long as Core and its Affiliates or Associates together beneficially own at least fifteen percent (15%) or more of the outstanding Voting Stock of the Corporation); provided, however, that such Person was not an Interested Stockholder prior to such transfer, sale, assignment, conveyance, hypothecation, encumbrance, or other disposition; or (z) any Person whose ownership of shares in excess of the fifteen percent (15%) limitation set forth herein is the result of action taken solely by the Corporation, provided that, for purposes of this clause (z) only, such Person shall be an Interested Stockholder if thereafter such Person acquires additional shares of Voting Stock of the Corporation, except as a

C-114

result of further action by the Corporation not caused, directly or indirectly, by such Person; provided, that, for the purpose of determining whether a Person is an Interested Stockholder, the Voting Stock of the Corporation deemed to be outstanding shall include Stock deemed to be owned by the Person through application of this definition of “owned” but shall not include any other unissued Stock of the Corporation which may be issuable pursuant to any agreement, arrangement or understanding, or upon exercise of conversion rights, warrants or options, or otherwise;

(f) “Owner,” including the terms “own” and “owned,” when used with respect to any Stock, means a Person that individually or with or through any of its Affiliates or Associates beneficially owns such Stock, directly or indirectly; or has (A) the right to acquire such Stock (whether such right is exercisable immediately or only after the passage of time) pursuant to any agreement, arrangement or understanding, or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise; provided, however, that a Person shall not be deemed the owner of Stock tendered pursuant to a tender or exchange offer made by such Person or any of such Person’s Affiliates or Associates until such tendered Stock is accepted for purchase or exchange; or (B) the right to vote such Stock pursuant to any agreement, arrangement or understanding; provided, however, that a Person shall not be deemed the owner of any Stock because of such Person’s right to vote such Stock if the agreement, arrangement or understanding to vote such Stock arises solely from a revocable proxy or consent given in response to a proxy or consent solicitation made to 10 or more Persons; or (C) has any agreement, arrangement or understanding for the purpose of acquiring, holding, voting (except voting pursuant to a revocable proxy or consent as described in (B) of this Section 4(f) of ARTICLE NINE), or disposing of such Stock with any other Person that beneficially owns, or whose Affiliates or Associates beneficially own, directly or indirectly, such Stock;

(g) “Person” means any individual, corporation, partnership, unincorporated association or other entity;

(h) “Stock” means, with respect to any corporation, any capital stock of such corporation and, with respect to any other entity, any equity interest of such entity; and

(i) “Voting Stock” means, with respect to any corporation, Stock of any class or series entitled to vote generally in the election of directors and, with respect to any entity that is not a corporation, any equity interest entitled to vote generally in the election of the governing body of such entity. Every reference to a percentage of Voting Stock in this ARTICLE NINE shall refer to such percentage of the votes of such Voting Stock.

C-115

outstanding shares of Voting Stock, voting together as a single class, at a meeting of the Corporation’s stockholders called for that purpose and (b) no provision of ARTICLE NINE of this Certificate of Incorporation may be altered, amended or repealed in any respect, nor may any provision of this Certificate of Incorporation inconsistent therewith be adopted, unless in addition to any other vote required by this Certificate of Incorporation or otherwise required by law, such alteration, amendment, repeal or adoption is approved by the affirmative vote of holders of at least eighty percent (80%) of the voting power of all outstanding shares of Voting Stock, voting together as a single class, at a meeting of the Corporation’s stockholders called for that purpose.

ARTICLE ELEVEN

Section 1. Exclusive Forum. Unless this Corporation consents in writing to the selection of an alternative forum, the Court of Chancery of the State of Delaware shall, to the fullest extent permitted by law, be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer, employee or stockholder of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware, this Certificate of Incorporation or the Bylaws or (iv) any action asserting a claim governed by the internal affairs doctrine; provided that for the avoidance of doubt, this provision, including for any “derivative action,” will not apply to suits to enforce a duty or liability created by the Securities Act, the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction. Unless the Corporation consents in writing to the selection of an alternative forum, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended. Failure to enforce the foregoing provisions would cause the Corporation irreparable harm and the Corporation shall be entitled to equitable relief, including injunctive relief and specific performance, to enforce the foregoing provisions.

FINAL FORM

AMENDED AND RESTATED BYLAWS

OF

FATHOM DIGITAL MANUFACTURING CORPORATION

A Delaware corporation

(Adopted as of                 , 2021)

ARTICLE I

OFFICES

Section 1. Offices. Fathom Digital Manufacturing Corporation (the “Corporation”) may have an office or offices other than its registered office at such place or places, either within or outside the State of Delaware, as the Board of Directors of the Corporation (the “Board of Directors”) may from time to time determine or the business of the Corporation may require. The registered office of the Corporation in the State of Delaware shall be as stated in the corporation’s certificate of incorporation as then in effect (the “Certificate of Incorporation”).

ARTICLE II

MEETINGS OF STOCKHOLDERS

Section 1. Place of Meetings. The Board of Directors may designate a place, if any, either within or outside the State of Delaware, as the place of meeting for any annual meeting or for any special meeting of stockholders.

Section 2. Annual Meeting. An annual meeting of the stockholders shall be held at such date and time as is specified by resolution of the Board of Directors. At the annual meeting, stockholders shall elect directors to succeed those whose terms expire at such annual meeting and transact such other business as properly may be brought before the annual meeting pursuant to Section 11 of this ARTICLE II of these Amended and Restated Bylaws (these “Bylaws”). The Board of Directors may postpone, reschedule or cancel any annual meeting of stockholders previously scheduled by the Board of Directors.

Section 3. Special Meetings. Special meetings of the stockholders may only be called in the manner provided in the Certificate of Incorporation. Business transacted at any special meeting of stockholders shall be limited to the purposes stated in the notice. The Board of Directors may postpone, reschedule or cancel any special meeting of stockholders previously scheduled by the Board of Directors.

Section 4. Notice of Meetings. Whenever stockholders are required or permitted to take action at a meeting, notice of the meeting shall be given that shall state the place, if any, date, and time of the meeting of the stockholders, the means of remote communications, if any, by which stockholders and proxyholders not physically present may be deemed to be present in person and vote at such meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called, shall be given, not less than 10 nor more than 60 days before the date on which the meeting is to be held, to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting, except as otherwise provided herein or required by law (meaning, here and hereinafter, as required from time to time by the General Corporation Law of the State of Delaware (the “DGCL”)) or the Certificate of Incorporation.

(a) Form of Notice. All such notices shall be delivered in writing or in any other manner permitted by the DGCL. If mailed, such notice shall be deemed given when deposited in the United States mail, postage prepaid,

C-118

addressed to the stockholder at his, her or its address as the same appears on the records of the Corporation. If delivered by courier service, notice shall be deemed given at the earlier of when the notice is received or left at such stockholder’s address as the same appears on the records of the Corporation. If given by electronic mail, notice shall be deemed given when directed to such stockholder’s electronic mail address unless the stockholder has notified the Corporation in writing or by electronic transmission of an objection to receiving notice by electronic mail or such notice is prohibited by the DGCL. Notice to stockholders may also be given by other forms of electronic transmission consented to by the stockholder. If given by facsimile telecommunication, such notice shall be deemed given when directed to a number at which the stockholder has consented to receive notice by facsimile. If given by a posting on an electronic network together with separate notice to the stockholder of such specific posting, such notice shall be deemed given upon the later of (x) such posting and (y) the giving of such separate notice. If notice is given by any other form of electronic transmission, such notice shall be deemed given when directed to the stockholder. An affidavit of the secretary or an assistant secretary of the Corporation, the transfer agent of the Corporation or any other agent of the Corporation that the notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

(b) Waiver of Notice. Whenever notice is required to be given under any provisions of the DGCL, the Certificate of Incorporation or these Bylaws, a written waiver thereof, signed by the stockholder entitled to notice, or a waiver by electronic transmission given by the stockholder entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Neither the business to be transacted at, nor the purpose of, any meeting of the stockholders of the Corporation need be specified in any waiver of notice of such meeting. Attendance of a stockholder of the Corporation at a meeting of such stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends for the express purpose of objecting at the beginning of the meeting to the transaction of any business because the meeting is not lawfully called or convened and does not further participate in the meeting.

(c) Notice by Electronic Transmission. Notwithstanding Section 4(a) of this ARTICLE II, a notice may not be given by electronic transmission from and after the time: (i) the Corporation is unable to deliver by electronic transmission two (2) consecutive notices given by the Corporation; and (ii) such inability becomes known to the secretary or an assistant secretary of the Corporation or to the transfer agent or other person responsible for the giving of notice. However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action. For purposes of these Bylaws, except as otherwise limited by applicable law, the term “electronic transmission” means any form of communication not directly involving the physical transmission of paper, including the use of, or participation in, one or more electronic networks or databases (including one or more distributed networks or databases), that creates a record that may be retained, retrieved and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such recipient through an automated process. A notice by electronic mail must include a prominent legend that the communication is an important notice regarding the Corporation. A notice by electronic mail will include any files attached thereto and any information hyperlinked to a website if such electronic mail includes the contact information of an officer or agent of the corporation who is available to assist with accessing such files or information.

Section 5. List of Stockholders. The Corporation shall prepare, at least 10 days before each meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, provided, however, if the record date for determining the stockholders entitled to vote is less than 10 days before the meeting date, the list shall reflect the stockholders entitled to vote as of the 10th day before the meeting date, arranged in alphabetical order and showing the address of each such stockholder and the number of shares registered in the name of each such stockholder. Nothing contained in this section shall require the Corporation to include electronic mail addresses or other electronic contact information on such list. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting for a period of at least 10 days prior to the meeting: (a) on a reasonably accessible electronic network, provided that the information required to gain access to such list is provided with the notice of the meeting, or (b) during ordinary business hours, at the principal place of business of the Corporation. In the event the Corporation determines to make the list available on an electronic network, the Corporation may take reasonable steps to ensure that such information is available only to stockholders of the Corporation. If the meeting is to be held

C-119

at a place, the list shall also be produced and kept at the time and place of the meeting during the whole time thereof, and may be inspected by any stockholder who is present. If the meeting is to be held solely by means of remote communication, then the list shall also be open to the examination of any stockholder during the whole time of the meeting on a reasonably accessible electronic network, and the information required to access such list shall be provided with the notice of the meeting. Except as otherwise provided by law, the list shall be the only evidence as to who are the stockholders entitled to examine the list of stockholders required by this Section 5 or to vote in person or by proxy at any meeting of stockholders.

Section 6. Quorum. The holders of a majority in voting power of the outstanding capital stock entitled to vote at the meeting, present in person or represented by proxy, shall constitute a quorum at all meetings of the stockholders, except as otherwise provided by law, by the Certificate of Incorporation or these Bylaws. If a quorum is not present, the chair of the meeting or the holders of a majority of the voting power present in person or represented by proxy at the meeting and entitled to vote at the meeting may adjourn the meeting to another time and/or place from time to time until a quorum shall be present or represented by proxy. When a specified item of business requires a vote by a class or series (if the Corporation shall then have outstanding shares of more than one class or series) voting as a separate class or series, the holders of a majority in voting power of the outstanding stock of such class or series entitled to vote thereon shall constitute a quorum (as to such class or series) for the transaction of such item of business. A quorum once established at a meeting shall not be broken by the withdrawal of enough votes to leave less than a quorum.

Section 7. Adjourned Meetings. Any meeting of stockholders, annual or special, may adjourn from time to time to reconvene at the same or some other place. When a meeting is adjourned to another time and place, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting. If after the adjournment a new record date for stockholders entitled to vote is fixed for the adjourned meeting, the Board of Directors shall fix a new record date for notice of such adjourned meeting, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors and, except as otherwise required by law, shall not be more than 60 days nor less than 10 days before the date of such adjourned meeting, and shall give notice of the adjourned meeting to each stockholder of record entitled to vote at such adjourned meeting as of the record date fixed for notice of such adjourned meeting.

Section 8. Vote Required. Subject to the rights of the holders of any series of preferred stock then outstanding, when a quorum has been established, all matters other than the election of directors shall be determined by the affirmative vote of the majority of voting power of capital stock present in person or represented by proxy at the meeting and entitled to vote on the subject matter, unless by express provisions of the DGCL or other applicable law, the rules of any stock exchange upon which the Corporation’s securities are listed, any regulation applicable to the Corporation or its securities, the Certificate of Incorporation or these Bylaws a minimum or different vote is required, in which case such minimum or different vote shall be the required vote for such matter. Directors shall be elected by a plurality of the votes cast.

Section 9. Voting Rights. Subject to the rights of the holders of any series of preferred stock then outstanding, except as otherwise provided by the DGCL, the Certificate of Incorporation or these Bylaws, each stockholder entitled to vote at any meeting of stockholders shall be entitled to one vote in person or by proxy for each share of capital stock held by such stockholder which has voting power upon the matter in question. Voting at meetings of stockholders need not be by written ballot.

Section 10. Proxies. Each stockholder entitled to vote at a meeting of stockholders or to express consent to corporate action in writing without a meeting may authorize another person or persons to act for such stockholder by proxy, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. A duly executed proxy shall be irrevocable if it states that it is irrevocable and if, and only as

C-120

long as, it is coupled with an interest sufficient in law to support an irrevocable power. A proxy may be made irrevocable regardless of whether the interest with which it is coupled is an interest in the stock itself or an interest in the Corporation generally.

Section 11. Advance Notice of Stockholder Business and Director Nominations.

(a) Business at Annual Meetings of Stockholders.

(i) Only such business (other than nominations of persons for election to the Board of Directors, which must be made in compliance with and are governed exclusively by Section 11(b) of this ARTICLE II) shall be conducted at an annual meeting of the stockholders as shall have been brought before the meeting (A) as specified in the notice of meeting (or any supplement thereto) given by or at the direction of the Board of Directors or any duly authorized committee thereof, (B) by or at the direction of the Board of Directors or any duly authorized committee thereof, or (C) by any stockholder of the Corporation who (1) was a stockholder of record at the time of giving of notice provided for in Section 11(a)(iii) of this ARTICLE II, on the record date for determination of stockholders of the Corporation entitled to vote at the meeting, and at the time of the annual meeting, (2) at the time of the meeting, is entitled to vote at the meeting and (3) complies with the notice procedures set forth in Section 11(a)(iii) of this ARTICLE II. For the avoidance of doubt, the foregoing clause (C) of this Section 11(a)(i) of ARTICLE II shall be the exclusive means for a stockholder to propose such business (other than business included in the Corporation’s proxy materials pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or business brought by CORE (as defined below) and any entity that controls, is controlled by or under common control with CORE (other than the Corporation and any company that is controlled by the Corporation) and any investment funds managed by CORE (the “CORE Affiliates”) at any time prior to the Advance Notice Trigger Date (as defined below)) before an annual meeting of stockholders.

Notices delivered pursuant to this Section 11(b) of ARTICLE II will be deemed received on any given day if received prior to the Close of Business on such day (and otherwise on the next succeeding day).

Section 12. Fixing a Record Date for Stockholder Meetings.

If the Board of Directors so fixes a date, such date shall also be the record date for determining the stockholders entitled to vote at such meeting unless the Board of Directors determines, at the time it fixes such record date, that a later date on or before the date of the meeting shall be the date for making such determination. If no record date is fixed by the Board of Directors, the record date for determining stockholders entitled to notice of or to vote at a meeting of stockholders shall be the Close of Business on the next day preceding the day on which notice is first given, or, if notice is waived, at the Close of Business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board of Directors may fix a new record date for the adjourned meeting in conformity herewith; and in such case shall also fix as the record date for stockholders entitled to notice of such adjourned meeting the same or an earlier date as that fixed for determination of stockholders entitled to vote in accordance with the foregoing provisions of this Section 12 at the adjourned meeting.

C-127

Section 13. Action by Stockholders Without a Meeting. So long as preferred stockholders of the Corporation have the right to act by written consent in accordance with Section 1 of ARTICLE SEVEN of the Certificate of Incorporation, the following provisions shall apply:

(a) Record Date. For the purpose of determining the stockholders entitled to consent to corporate action in writing without a meeting as may be permitted by the Certificate of Incorporation or the certificate of designation relating to any outstanding class or series of preferred stock, the Board of Directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the Board of Directors, and which record date shall not be more than ten (10) (or the maximum number permitted by applicable law) days after the date on which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take action by written consent shall, by written notice delivered to the Secretary at the Corporation’s principal place of business during regular business hours, request that the Board of Directors fix a record date, which notice shall include the text of any proposed resolutions. Notices delivered pursuant to Section 13(a) of this ARTICLE II will be deemed received on any given day only if received prior to the Close of Business on such day (and otherwise shall be deemed received on the next succeeding Business Day). The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such written notice is properly delivered to and deemed received by the Secretary, adopt a resolution fixing the record date (unless a record date has previously been fixed by the Board of Directors pursuant to the first sentence of this Section 13(a)). If no record date has been fixed by the Board of Directors pursuant to this Section 13(a) or otherwise within ten (10) days of receipt of a valid request by a stockholder, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the Board of Directors is required pursuant to applicable law, shall be the first date after the expiration of such ten (10) day time period on which a signed written consent setting forth the action taken or proposed to be taken is delivered to the Corporation pursuant to Section 13(b); provided, however, that if prior action by the Board of Directors is required by applicable law, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall in such an event be at the Close of Business on the day on which the Board of Directors adopts the resolution taking such prior action.

(b) Generally. No written consent shall be effective to take the corporate action referred to therein unless written consents signed by a sufficient number of stockholders to take such action are delivered to the Corporation, in the manner required by this Section 13, within sixty (60) (or the maximum number permitted by applicable law) days of the date of the earliest dated consent delivered to the Corporation in the manner required by applicable law. The validity of any consent executed by a proxy for a stockholder pursuant to an electronic transmission transmitted to such proxy holder by or upon the authorization of the stockholder shall be determined by or at the direction of the Secretary. A written record of the information upon which the person making such determination relied shall be made and kept in the records of the proceedings of the stockholders. Any such consent shall be inserted in the minute book as if it were the minutes of a meeting of stockholders. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given by the Corporation (at its expense) to those stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for notice of such meeting had been the date that written consent signed by a sufficient number of holders to take the action were delivered to the Corporation.

Section 14. Conduct of Meetings.

(a) Generally. Meetings of stockholders shall be presided over by the Chair of the Board, if any, or in the Chair’s absence or disability, the Chair’s designee, or if the Chair has made no such designation or in the designee’s absence or disability, by a chair designated by the Board of Directors, or in the absence or disability of such person, by a chair chosen at the meeting. The Secretary shall act as secretary of the meeting, but in the Secretary’s absence or disability the chair of the meeting may appoint any person to act as secretary of the meeting.

C-128

(b) Rules, Regulations and Procedures. The Board of Directors may adopt by resolution such rules, regulations and procedures for the conduct of any meeting of stockholders of the Corporation as it shall deem appropriate including, without limitation, such guidelines and procedures as it may deem appropriate regarding the participation by means of remote communication of stockholders and proxyholders not physically present at a meeting. Except to the extent inconsistent with such rules, regulations and procedures as adopted by the Board of Directors, the chair of any meeting of stockholders shall have the right and authority to prescribe such rules, regulations and procedures and to do all such acts as, in the judgment of such chair, are appropriate for the proper conduct of the meeting. Such rules, regulations or procedures, whether adopted by the Board of Directors or prescribed by the chair of the meeting, may include, without limitation, the following: (i) the establishment of an agenda or order of business for the meeting; (ii) rules and procedures for maintaining order at the meeting and the safety of those present; (iii) limitations on attendance at or participation in the meeting to stockholders of record of the Corporation, their duly authorized and constituted proxies or such other persons as the chair of the meeting shall determine; (iv) restrictions on entry to the meeting after the time fixed for the commencement thereof; (v) limitations on the time allotted to questions or comments by participants; and (vi) restrictions on the use of mobile phones, audio or video recording devices and similar devices at the meeting. The chair of the meeting of stockholders, in addition to making any other determinations that may be appropriate to the conduct of the meeting, shall, if the facts warrant, determine and declare to the meeting that a nomination or matter or business was not properly brought before the meeting and if such chair should so determine, such chair shall so declare to the meeting and any such matter or business not properly brought before the meeting shall not be transacted or considered. Unless and to the extent determined by the Board of Directors or the chair of the meeting, meetings of stockholders shall not be required to be held in accordance with the rules of parliamentary procedure. The chair of the meeting shall announce at the meeting when the polls for each matter to be voted upon at the meeting will be opened and closed. After the polls close, no ballots, proxies or votes or any revocations or changes thereto may be accepted. The chair of the meeting shall have the power, right and authority, for any or no reason, to convene, recess and/or adjourn any meeting of stockholders.

(c) Inspectors of Elections. The Corporation may, and to the extent required by law shall, in advance of any meeting of stockholders, appoint one or more inspectors of election to act at the meeting and make a written report thereof. One or more other persons may be designated as alternate inspectors to replace any inspector who fails to act. If no inspector or alternate is able to act at a meeting of stockholders, the chair of the meeting shall appoint one or more inspectors to act at the meeting. Unless otherwise required by law, inspectors may be officers, employees or agents of the Corporation. No person who is a candidate for an office at an election may serve as an inspector at such election. Each inspector, before entering upon the discharge of such inspector’s duties, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of such inspector’s ability. The inspector shall have the duties prescribed by law and, when the vote is completed, shall make a certificate of the result of the vote taken and of such other facts as may be required by law.

Such right to dissent shall not apply to any member who voted in favor of such action.

Section 6. Chair of the Board, Quorum, Required Vote and Adjournment. The Board of Directors may elect a Chair of the Board.

At any meeting of the Board of Directors, business shall be transacted in such order and manner as the Board of Directors may from time to time determine. If a quorum shall not be present at any meeting of the Board of Directors, the directors present thereat may, to the fullest extent permitted by law, adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum shall be present.

The Board of Directors may designate one or more directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Except to the extent restricted by applicable law or the Certificate of Incorporation, each such committee, to the extent provided by the DGCL and in the resolution creating it, shall have and may exercise all the powers and authority of the Board of Directors. Each such committee shall serve at the pleasure of the Board of Directors. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors upon request.

(b) Each committee of the Board of Directors may fix its own rules of procedure and shall hold its meetings as provided by such rules, except as may otherwise be provided by a resolution of the Board of Directors designating such committee. Unless otherwise provided in such a resolution, the presence of at least a majority of the members of the committee shall be necessary to constitute a quorum. All matters shall be determined by a majority vote of the members present at a meeting at which a quorum is present. Unless otherwise provided in such a resolution, in the event that a member and that member’s alternate, if alternates are designated by the Board of Directors, of such committee is or are absent or disqualified, the member or members present at any meeting and not disqualified from voting, whether or not such member or members constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in place of any such absent or disqualified member.

Section 8. Action by Written Consent. Unless otherwise restricted by the Certificate of Incorporation or these Bylaws, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of the Board of Directors or such committee, as the case may be, consent thereto in writing or by electronic transmission. After the action is taken, the consent or consents relating thereto shall be filed with the minutes of proceedings of the board or committee in the same paper form or electronic form as the minutes are maintained.

Section 9. Compensation. The Board of Directors shall have the authority to fix the compensation, including fees, reimbursement of expenses and equity compensation, of directors for services to the Corporation in any capacity, including for attendance of meetings of the Board of Directors or participation on any committees. No such payment shall preclude any director from serving the Corporation in any other capacity and receiving compensation therefor.

Section 10. Reliance on Books and Records. A member of the Board of Directors, or a member of any committee designated by the Board of Directors shall, in the performance of such member’s duties, be fully protected in relying in good faith upon records of the Corporation and upon such information, opinions, reports or statements presented to the Corporation by any of the Corporation’s officers or employees, or committees of the Board of Directors, or by any other person as to matters the member reasonably believes are within such other person’s professional or expert competence and who has been selected with reasonable care by or on behalf of the Corporation.

C-131

Section 11. Telephonic and Other Meetings. Unless restricted by the Certificate of Incorporation, any one or more members of the Board of Directors or any committee thereof may participate in a meeting of the Board of Directors or such committee by means of conference telephone or other communications equipment by means of which all persons participating in the meeting can hear each other. Participation by such means shall constitute presence in person at a meeting.

Section 11. Appointed Officers. In addition to officers designated by the Board of Directors in accordance with this ARTICLE IV, the Chief Executive Officer shall have the authority, subject to the prior consent of the Board of Directors, to appoint other officers below the level of Board-appointed Vice President as the Chief Executive Officer may from time to time deem expedient and may designate for such officers titles that appropriately reflect their positions and responsibilities. Such appointed officers shall have such powers and shall perform such

C-133

duties as may be assigned to them by the Chief Executive Officer or the senior officer to whom they report (in each case, in consultation with the Board of Directors), consistent with corporate policies. An appointed officer shall serve until the earlier of such officer’s resignation or such officer’s removal by the Board of Directors, or by the Chief Executive Officer with the consent of the Board of Directors, at any time, either with or without cause.

Section 12. Other Officers, Assistant Officers and Agents.

ARTICLE V

CERTIFICATES OF STOCK

Section 1. Form. The shares of stock of the Corporation shall be represented by certificates, provided that the Board of Directors may provide by resolution that some or all of any or all classes or series of its stock shall be uncertificated shares. Any such resolution shall not apply to shares represented by a certificate until such certificate is surrendered to the Corporation. If shares are represented by certificates, the certificates shall be in such form as required by applicable law and as determined by the Board of Directors. Each certificate shall certify the number of shares owned by such holder in the Corporation and shall be signed by, or in the name of the Corporation by two authorized officers of the Corporation including, but not limited to, the Chair of the Board (if an officer), the President, a Vice President, the Treasurer, the Secretary and an Assistant Secretary of the Corporation. Any or all signatures on the certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed, or whose facsimile signature or signatures have been used on, any such certificate or certificates shall cease to be such officer, transfer agent or registrar of the Corporation whether because of death, resignation or otherwise before such certificate or certificates have been issued by the Corporation, such certificate or certificates may nevertheless be issued as though the person or persons who signed such certificate or certificates or whose facsimile signature or signatures have been used thereon had not ceased to be such officer, transfer agent or registrar of the Corporation at the date of issue. All certificates for shares shall be consecutively numbered or otherwise identified. The Board of Directors may appoint a bank or trust company organized under the laws of the United States or any state thereof to act as its transfer agent or registrar, or both in connection with the transfer of any class or series of securities of the Corporation. The Corporation, or its designated transfer agent or other agent, shall keep a book or set of books to be known as the stock transfer books of the Corporation, containing the name of each holder of record, together with such holder’s address and the number and class or series of shares held by such holder and the date of issue. When shares are represented by certificates, the Corporation shall issue and deliver to each holder to whom such shares have been issued or transferred, certificates representing the shares owned by such holder, and shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof or by such holder’s attorney duly authorized in writing, upon surrender to the Corporation or its designated transfer agent or other agent of the certificate or certificates for such shares endorsed by the appropriate person or persons, with such evidence of the authenticity of such endorsement, transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps. In that event, it shall be the duty of the Corporation to issue a new certificate to the person entitled thereto, cancel the old certificate or certificates and record the transaction on its books. When shares are not represented by certificates, shares of stock of the Corporation shall only be transferred on the books of the Corporation by the holder of record thereof

C-134

or by such holder’s attorney duly authorized in writing, with such evidence of the authenticity of such transfer, authorization and other matters as the Corporation may reasonably require, and accompanied by all necessary stock transfer stamps, and within a reasonable time after the issuance or transfer of such shares, the Corporation shall, if required by applicable law, send the holder to whom such shares have been issued or transferred a written statement of the information required by applicable law. Unless otherwise provided by applicable law, the Certificate of Incorporation, Bylaws or any other instrument, the rights and obligations of the holders of uncertificated stock and the rights and obligations of the holders of certificates representing stock of the same class and series shall be identical.

Section 2. Lost Certificates. The Corporation may issue or direct a new certificate or certificates or uncertificated shares to be issued in place of any certificate or certificates previously issued by the Corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the owner of the lost, stolen or destroyed certificate. When authorizing such issue of a new certificate or certificates or uncertificated shares, the Corporation may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his or her legal representative, to give the Corporation a bond in such sum as it may direct, sufficient to indemnify the Corporation against any claim that may be made against the Corporation on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate or uncertificated shares.

Section 3. Registered Stockholders. The Corporation shall be entitled to recognize the exclusive right of a person registered on its records as the owner of shares of stock to receive dividends, to vote, to receive notifications and otherwise to exercise all the rights and powers of an owner, except as otherwise required by applicable law. The Corporation shall not be bound to recognize any equitable or other claim to or interest in such share or shares of stock on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise required by applicable law.

Section 4. Fixing a Record Date for Purposes Other Than Stockholder Meetings or Actions by Written Consent. In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment or any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purposes of any other lawful action (other than stockholder meetings and stockholder written consents which are expressly governed by Sections 12 and 13 of ARTICLE II hereof), the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the Close of Business on the day on which the Board of Directors adopts the resolution relating thereto.

ARTICLE VI

GENERAL PROVISIONS

Section 1. Dividends. Subject to and in accordance with applicable law, the Certificate of Incorporation and any certificate of designation relating to any series of preferred stock, dividends upon the shares of capital stock of the Corporation may be declared and paid by the Board of Directors, in accordance with applicable law. Dividends may be paid in cash, in property or in shares of the Corporation’s capital stock, subject to the provisions of applicable law and the Certificate of Incorporation. Before payment of any dividend, there may be set aside out of any funds of the Corporation available for dividends a reserve or reserves for any proper purpose. The Board of Directors may modify or abolish any such reserves in the manner in which they were created.

Section 2. Checks, Notes, Drafts, Etc. All checks, notes, drafts or other orders for the payment of money of the Corporation shall be signed, endorsed or accepted in the name of the Corporation by such officer, officers, person or persons as from time to time may be designated by the Board of Directors or by an officer or officers authorized by the Board of Directors to make such designation.

C-135

In addition to the powers otherwise granted to officers pursuant to ARTICLE IV hereof, the Board of Directors may authorize any officer or officers, or any agent or agents, in the name and on behalf of the Corporation to enter into or execute and deliver any and all deeds, bonds, mortgages, contracts and other obligations or instruments, and such authority may be general or confined to specific instances.

Section 4. Fiscal Year. The fiscal year of the Corporation shall be fixed by resolution of the Board of Directors.

Section 5. Corporate Seal. The Board of Directors may provide a corporate seal which shall be in the form of a circle and shall have inscribed thereon the name of the Corporation and the words “Corporate Seal, Delaware.” The seal may be used by causing it or a facsimile thereof to be impressed or affixed or reproduced or otherwise. Notwithstanding the foregoing, no seal shall be required by virtue of this Section.

Section 6. Voting Securities Owned By Corporation. Voting securities in any other corporation or entity held by the Corporation shall be voted by the Chair of the Board, Chief Executive Officer, the President or the Chief Financial Officer, unless the Board of Directors specifically confers authority to vote with respect thereto, which authority may be general or confined to specific instances, upon some other person or officer. Any person authorized to vote securities shall have the power to appoint proxies, with general power of substitution.

Section 7. Facsimile Signatures. In addition to the provisions for use of facsimile signatures elsewhere specifically authorized in these Bylaws and subject to applicable law, facsimile signatures of any officer or officers of the Corporation may be used.

Section 8. Section Headings. Section headings in these Bylaws are for convenience of reference only and shall not be given any substantive effect in limiting or otherwise construing any provision herein.

Section 9. Inconsistent Provisions. In the event that any provision (or part thereof) of these Bylaws is or becomes inconsistent with any provision of the Certificate of Incorporation, the DGCL, any other applicable law or the Investor Rights Agreement, the provision (or part thereof) of these Bylaws shall be deemed to have been revised to conform to the applicable provision of the Certificate of Incorporation, the DGCL, other applicable law or the Investor Rights Agreement, as the case may be, the applicable provisions of which shall be deemed incorporated herein by reference, so as to eliminate any such inconsistency.

ARTICLE VII

INDEMNIFICATION

Section 1. Right to Indemnification and Advancement. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved (including involvement, without limitation, as a witness) in any actual or threatened action, suit or proceeding, whether civil, criminal, administrative or investigative (a “proceeding”), by reason of the fact that he or she is or was a director or officer of the Corporation or, while a director or officer of the Corporation, is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director or officer or in any other capacity while serving as a director or officer, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the DGCL, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Corporation to provide broader indemnification rights than permitted prior thereto), against all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, excise taxes or penalties under the Employee Retirement Income Security Act of 1974, as amended from time to time (“ERISA”) and any other penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith and such indemnification shall continue as to an indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the indemnitee’s

C-136

heirs, executors and administrators; provided, however, that, except as provided in this Section 2 of this ARTICLE VII with respect to proceedings to enforce rights to indemnification and advance of expenses (as defined below), the Corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized in the specific case by the Board of Directors of the Corporation. The rights to indemnification and advance of expenses conferred in this Section 1 of ARTICLE VII shall be contract rights. In addition to the right to indemnification conferred herein, an indemnitee shall also have the right, to the fullest extent not prohibited by law, to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition (an “advance of expenses”); provided, however, that if and to the extent that the DGCL requires, an advance of expenses shall be made only upon delivery to the Corporation of an undertaking (an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 1 or otherwise. The Corporation may also, by action of its Board of Directors, provide indemnification and advancement to employees and agents of the Corporation. Any reference to an officer of the Corporation in this ARTICLE VII shall be deemed to refer exclusively to the Chair of the Board of Directors, Chief Executive Officer, President, Secretary and Treasurer of the Corporation appointed pursuant to ARTICLE IV, and to any Vice President, Assistant Secretary, Assistant Treasurer or other officer of the Corporation appointed by the Board of Directors pursuant to ARTICLE IV of these By-laws, and any reference to an officer of any other enterprise shall be deemed to refer exclusively to an officer appointed by the board of directors or equivalent governing body of such other entity pursuant to the certificate of incorporation and bylaws or equivalent organizational documents of such other enterprise. The fact that any person who is or was an employee of the Corporation or an employee of any other enterprise has been given or has used the title of “Vice President” or any other title that could be construed to suggest or imply that such person is or may be an officer of the Corporation or of such other enterprise shall not result in such person being constituted as, or being deemed to be, an officer of the Corporation or of such other enterprise for purposes of this ARTICLE VII.

Section 2. Procedure for Indemnification. Any claim for indemnification or advance of expenses by an indemnitee under this Section 2 of ARTICLE VII shall be made promptly, and in any event within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the director or officer has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), upon the written request of the indemnitee. If the Corporation denies a written request for indemnification or advance of expenses, in whole or in part, or if payment in full pursuant to such request is not made within forty-five days (or, in the case of an advance of expenses, twenty days, provided that the indemnitee has delivered the undertaking contemplated by Section 1 of this ARTICLE VII if required), the right to indemnification or advances as granted by this ARTICLE VII shall be enforceable by the indemnitee in any court of competent jurisdiction. Such person’s costs and expenses incurred in connection with successfully establishing his or her right to indemnification, in whole or in part, in any such action shall also be indemnified by the Corporation to the fullest extent permitted by applicable law. It shall be a defense to any such action (other than an action brought to enforce a claim for the advance of expenses where the undertaking required pursuant to Section 1 of this ARTICLE VII, if any, has been tendered to the Corporation) that the claimant has not met the applicable standard of conduct which make it permissible under the DGCL for the Corporation to indemnify the claimant for the amount claimed, but the burden of proof shall be on the Corporation to the fullest extent permitted by law. Neither the failure of the Corporation (including its Board of Directors, a committee thereof, independent legal counsel or its stockholders) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the DGCL, nor an actual determination by the Corporation (including its Board of Directors, independent legal counsel or its stockholders) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

Section 3. Insurance. The Corporation may purchase and maintain insurance on its own behalf and on behalf of any person who is or was or has agreed to become a director, officer, employee or agent of the Corporation or is

C-137

or was serving at the request of the Corporation as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, joint venture, limited liability company, trust or other enterprise against any expense, liability or loss asserted against him or her and incurred by him or her in any such capacity, or arising out of his or her status as such, whether or not the Corporation would have the power to indemnify such person against such expenses, liability or loss under the DGCL.

Section 4. Service for Subsidiaries. Any person serving as a director, officer, partner, member, trustee, administrator, employee or agent of another corporation, partnership, limited liability company, joint venture, trust or other enterprise, at least 50% of whose equity interests are owned by the Corporation (a “subsidiary” for purposes of this ARTICLE VII) shall be conclusively presumed to be serving in such capacity at the request of the Corporation.

Section 5. Reliance. Persons who served as directors or officers of Altimar Cayman (as defined in the Certificate of Incorporation), and Persons who after the date of the adoption of this provision become or remain directors or officers of the Corporation or who, while a director or officer of the Corporation, become or remain a director, officer, employee or agent of a subsidiary, shall be conclusively presumed to have relied on the rights to indemnity, advance of expenses and other rights contained in this ARTICLE VII in entering into or continuing such service. To the fullest extent permitted by law, the rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall apply to claims made against an indemnitee arising out of acts or omissions which occurred or occur both prior and subsequent to the adoption hereof. Any amendment, alteration or repeal of this ARTICLE VII that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit, eliminate, or impair any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment or repeal.

Section 6. Non-Exclusivity of Rights; Continuation of Rights of Indemnification. The rights to indemnification and to the advance of expenses conferred in this ARTICLE VII shall not be exclusive of any other right which any person may have or hereafter acquire under the Certificate of Incorporation or under any statute, by-law, agreement, vote of stockholders or disinterested directors or otherwise. All rights to indemnification under this ARTICLE VII shall be deemed to be a contract between the Corporation and each director or officer of the Corporation who serves or served in such capacity at any time while this ARTICLE VII is in effect. Any repeal or modification of this ARTICLE VII or repeal or modification of relevant provisions of the DGCL or any other applicable laws shall not in any way diminish any rights to indemnification and advancement of expenses of such director or officer or the obligations of the Corporation arising hereunder with respect to any proceeding arising out of, or relating to, any actions, transactions or facts occurring prior to the final adoption of such repeal or modification.

Section 7. Merger or Consolidation. For purposes of this ARTICLE VII, references to the “Corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this ARTICLE VII with respect to the resulting or surviving corporation as he or she would have with respect to such constituent corporation if its separate existence had continued.

Section 8. Savings Clause. To the fullest extent permitted by law, if this ARTICLE VII or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the Corporation shall nevertheless indemnify and advance expenses to each person entitled to indemnification under Section 1 of this ARTICLE VII as to all expense, liability and loss (including attorneys’ fees and related disbursements, judgments, fines, ERISA excise taxes and penalties and any other penalties and amounts paid or to be paid in settlement) actually and reasonably incurred or suffered by such person and for which indemnification and advancement of expenses is

C-138

available to such person pursuant to this ARTICLE VII to the fullest extent permitted by any applicable portion of this ARTICLE VII that shall not have been invalidated.

ARTICLE VIII

AMENDMENTS

These Bylaws may be amended, altered, changed or repealed or new Bylaws adopted only in accordance with Section 1 of ARTICLE ELEVEN of the Certificate of Incorporation.

2.2 Election of Directors.

(a) From the Effective Date, CORE Designator shall have the right, but not the obligation, to nominate to the Board a number of designees (such persons, the “CORE Nominees”) equal to at least: (i) a majority of the Total Number of Directors (as defined below), so long as the CORE Investors Beneficially Own shares of Common Stock representing at least 50% of the Original Amount (as defined below), (ii) 35% of the Total Number of Directors, in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 20% but less than 35% of the Original Amount, (iii) 20% of the Total Number of Directors, in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 10% but less than 20% of the Original Amount and (iv) 1 (one) Director (as defined below), in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 5% of the Original Amount. For purposes of calculating the number of directors that CORE Designator is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the nearest whole number (e.g., 11/4 Directors shall equate to 2 Directors) and any such calculations shall be made after taking into account any increase in the Total Number of Directors.

(b) In the event that CORE Designator has nominated less than the total number of designees that CORE Designator is entitled to nominate pursuant to Section 2.2(a), CORE Designator shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action, to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable CORE Designator to nominate and effect the election or appointment of such additional individuals, whether by increasing the size of the Board, or otherwise and (y) to designate such additional individuals nominated by CORE Designator to fill such newly created vacancies or to fill any other existing vacancies.

C-146

(c) In addition to the nomination rights set forth in Section 2.2(a) above, from the Effective Date, for so long as the CORE Investors Beneficially Own shares of Common Stock representing at least 5% of the Original Amount, CORE Designator shall have the right, but not the obligation, to designate a person (a “Non-Voting Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting observer capacity. Any such Non-Voting Observer shall be permitted to attend all meetings of the Board. CORE Designator shall have the right to remove and replace its Non-Voting Observer at any time and from time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to Directors and (ii) copies of any materials prepared for meetings of the Board that are furnished to the Directors no later than the time such materials are furnished to the Directors; provided, that (x) such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality agreements of the Company generally applicable to directors of the Company or as the Company reasonably requests and (y) the Company reserves the right to withhold any information and to exclude such Non-Voting Observer from any meeting or portion thereof to the extent access to such materials or attendance at such meeting would be reasonably likely to adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest; provided, further, that failure to deliver notice, or materials, to such Non-Voting Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not, by itself, impair the validity of any action taken by such Board at such meeting.

(d) The Company shall pay all reasonable out-of-pocket expenses incurred by the CORE Nominees and the Non-Voting Observer in connection with the performance of his or her duties as a Director or a Non-Voting Observer and in connection with his or her attendance at any meeting of the Board. In addition, as promptly as practicable following the request by any CORE Nominee who is serving as a Director, the Company shall enter into an indemnification agreement with such CORE Nominee in the form entered into with the other members of the Board.

(e) No reduction in the number of shares of Common Stock that the CORE Investors Beneficially Own shall shorten the term of any incumbent director who is serving as a CORE Nominee.

(f) In the event that any CORE Nominee shall cease to serve for any reason, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate such person’s successor in accordance with this Agreement and the Board shall promptly fill the vacancy with such successor nominee; it being understood that any such designee shall serve the remainder of the term of the director whom such designee replaces.

(g) If a CORE Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate promptly another nominee and the director position for which the original CORE Nominee was nominated shall not be filled pending such designation.

(h) So long as CORE Designator has the right to nominate CORE Nominees under Section 2.2(a) or any such CORE Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage in an amount determined by the Board to be reasonable and customary, and the Company Charter and Amended and Restated Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification, exculpation and advancement of expenses to the fullest extent permitted under applicable law. Upon the removal or resignation of any CORE Nominee as a Director for any reason, the Company shall use commercially reasonable efforts to take all actions reasonably necessary to extend such director’s official liability insurance coverage for a period of not less than six (6) years from any such event in respect or any act or omission occurring at or prior to such event.

C-147

(i) If the size of the Board is expanded, CORE Designator shall be entitled to nominate a number of CORE Nominees to fill the newly created vacancies such that the total number of CORE Nominees serving on the Board following such expansion will be equal to that number of CORE Nominees that CORE Designator would be entitled to nominate in accordance with Section 2.2(a) if such expansion occurred immediately prior to any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall appoint such CORE Nominees to the Board.

(j) During such time as the Company is required by applicable law or the New York Stock Exchange or such other principal United States securities exchange on which the Class A Common Stock is listed, quoted, or admitted to trading (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable phase-in periods), CORE Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other “independent directors” then serving on the Board that are not CORE Nominees, the Board is comprised of a majority of “independent directors.”

(k) At any time that CORE Designator shall have any nomination rights under Section 2.2, except as required by Law or the rules and regulations of the Exchange, the Company shall not take any action, including making or recommending any amendment to the Company Charter or the Company’s Amended and Restated Bylaws that could reasonably be expected to adversely affect CORE Designator’s rights, respectively, under this Agreement, in each case without the prior written consent of CORE Designator.

(l) Any CORE Nominee will be subject to the Company’s customary due diligence process, including its review of a completed questionnaire and a background check. Based on the foregoing, the Company may object to any CORE Nominee if (a) it does so in good faith and (b) such objection is based upon any of the following: (i) such CORE Nominee was convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses); (ii) such CORE Nominee was the subject of any order, judgment, or decree not subsequently reversed, suspended or vacated of any court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice; or (B) engaging in any activity in connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws; (iii) such CORE Nominee was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated, of any federal or state authority barring, suspending or otherwise limiting for more than sixty (60) days the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such activity; (iv) such CORE Nominee was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission has not been subsequently reversed, suspended or vacated; (v) such CORE Nominee was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree or finding, not subsequently reversed, suspended or vacated, relating to a violation of any federal or state securities laws or regulations; or (vi) any other reason(s) that apply by reason of applicable Law, the rules and regulations of the Exchange or Company policy. In the event the Board reasonably finds the CORE Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (vi) and reasonably objects to the identified director, the CORE Designator shall be entitled to propose a different CORE Nominee to the Board within thirty (30) calendar days of the Company’s notice to the CORE Designator of its objection to the CORE Nominee and such replacement CORE Nominee shall be subject to the review process outlined above.

2.3 Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date that the CORE Investors cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each CORE Nominee is included in the Board’s slate of nominees to the stockholders (the “Board Slate”) for each election of directors; and (ii) each CORE Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement

C-148

thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. CORE Designator will promptly provide reporting to the Company after CORE Designator ceases to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, such that Company is informed of when this obligation terminates. The calculation of the number of CORE Nominees that CORE Designator is entitled to nominate to the Board Slate for any election of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by CORE (“CORE Voting Control”), as applicable, immediately prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission). Unless CORE Designator notifies the Company otherwise prior to the mailing to stockholders of the Director Election Proxy Statement relating to an election of directors, the CORE Nominees for such election shall be presumed to be the same CORE Nominees currently serving on the Board, and no further action shall be required of CORE Designator for the Board to include such CORE Nominees on the Board’s Slate; provided, that, in the event CORE Designator is no longer entitled to nominate the full number of CORE Nominees then serving on the Board, CORE Designator shall provide advance written notice to the Company, of which currently serving CORE Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of CORE Nominees. If CORE Designator fails to provide such notice prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then serving on the Board shall determine which of the CORE Nominees of CORE Designator then serving on the Board will be included in the Board Slate.

2.4 Compensation. Except to the extent any CORE Designator may otherwise notify the Company with respect to such CORE Designator’s CORE Nominees, each CORE Nominee shall be entitled to compensation consistent with the Director compensation received by other Directors, including any fees and equity awards.

2.5 Other Rights of CORE Nominees. Except as provided in Section 2.3, each CORE Nominee serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of the foregoing, the Company shall, to the maximum extent permitted by applicable Law, indemnify, exculpate, and reimburse fees and expenses of the CORE Nominees (including by entering into an indemnification agreement in a form substantially similar to the Company’s form director indemnification agreement) and provide the CORE Nominees with director and officer insurance to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the Company Charter or Amended and Restated Bylaws of the Company, applicable Law or otherwise.

2.6 Director Independence. Notwithstanding anything to the contrary herein, the parties hereto shall ensure the composition of the Board will continue to meet all requirements for a company listed on the New York Stock Exchange (or such other stock exchange on which the Class A Common Stock may be listed from time to time), including with respect to director independence.

REGISTRATIONS AND OFFERINGS

2.1 Shelf Registration.

2.1.1 Filing. The Company shall file within 30 days of the Closing Date, and use commercially reasonable efforts to cause to be declared effective as soon as practicable thereafter, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a Shelf Registration on Form S¬3 (the “Form S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on a delayed or continuous basis. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. The

C-164

Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3 and, in any event, within 10 days following such date.

2.1.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

2.1.3 Additional Registerable Securities. In the event that any Investor holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a CORE Investor or any Sponsor Investor, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, the Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof.

2.1.4 Requests for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf is on file with the Commission, any CORE Investor or any Sponsor Investor (any of such Investors being, in such case, a “Demanding Investor”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other coordinated offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the Demanding Investor with a total offering price reasonably expected to exceed, in the aggregate, $50 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. The Demanding Investor initiating the request shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval (which shall not be unreasonably withheld, conditioned or delayed). Notwithstanding anything to the contrary in this Section 2.1.4 and this Agreement, there shall be no limit to the number of Underwritten Shelf Takedowns that may be requested by any Demanding Investor. Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Investors and the Investors requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Investors”) (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Investors and the Requesting Investors (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, before including any shares of Common Stock or other equity securities proposed to be sold by Company or by other holders of Common Stock or other equity securities the following: (i) first, the Registrable Securities of the Demanding Investors and the Requesting Investors (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Investor and Requesting Investor (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities that the Demanding Investors and Requesting Investors have requested be included in such Underwritten Shelf Takedown) that can be sold without exceeding the Maximum Number of Securities, (ii) second, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i), the Common Stock or other equity securities that Company desires to sell, which can be sold without exceeding the Maximum Number of Securities and (iii) third, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i) and 2.1.5 (ii), the Common Stock or other equity securities of any other Investor or any other person that Company is obligated to include in such Underwritten Offering pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities. To facilitate the allocation of Registrable Securities in accordance with the above provisions, the Company or the Underwriters may round the number of shares allocated to any Investor to the nearest 100 shares. The Company shall not be required to include any Registrable Securities in such Underwritten Shelf Takedown unless the Investors accept the terms of the underwriting as agreed upon between the Company and its Underwriters.

2.1.6 Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, a majority-in-interest of the Demanding Investors initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided that any Core Investor or a Sponsor Investor may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by such Investors or any of their respective Permitted Transferees, as applicable. If withdrawn, a demand for an Underwritten Shelf Takedown shall not constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Investors that had elected to participate in such Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6.

2.2 Piggyback Registration.

2.2.1 Piggyback Rights. Subject to Section 2.4.3, if the Company or any Investor proposes to conduct a registered offering of, or if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten Shelf

Subject to Section 2.2.2, the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Investors pursuant to this Section 2.2.1 to be included therein on the same terms and conditions as any similar securities of the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Investor’s Registrable Securities in a Piggyback Registration shall be subject to such Investor’s agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering.

2.2.2 Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration, in good faith, advises the Company and the Investors of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares of Common Stock or other equity securities that the Company desires to sell, taken together with (i) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Investors of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(a) If the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration or registered offering (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Investors exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Investor has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Investors have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(b) If the Registration or registered offering is pursuant to a request by persons or entities other than the Investors of Registrable Securities, then the Company shall include in any such Registration or registered offering (A) first, the shares of Common Stock or other equity securities, if any, of such requesting

C-167

persons or entities, other than the Investors of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Investors exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Investor has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Investors have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities; and

(c) If the Registration or registered offering is pursuant to a request by Investor(s) of Registrable Securities pursuant to Section 2.1 hereof, then the Company shall include in any such Registration or registered offering securities pursuant to Section 2.1.5.

2.2.3 Piggyback Registration Withdrawal. Any Investor of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from an Underwritten Shelf Takedown, and related obligations, shall be governed by Section 2.1.6) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration, the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.6), the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

2.2.4 Unlimited Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6, any Piggyback Registration effected pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4 hereof.

2.3 Market Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade), each Investor is given an opportunity to participate in the Underwritten Offering pursuant to the terms of this Agreement agrees that it shall not Transfer any shares of Common Stock or other equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during the 90-day period beginning on the date of pricing of such offering or such shorter period during which the Company agrees not to conduct an underwritten primary offering of Common Stock, except in the event the Underwriters managing the offering otherwise agree by written consent. Each Investor agrees to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Investors).

2.4 Block Trades.

2.4.1 Notwithstanding the foregoing, at any time and from time to time when an effective Shelf is on file with the Commission and effective, if a Demanding Investor wishes to engage in an underwritten or other coordinated registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), with a total offering price reasonably expected to exceed, in the aggregate, either (x) $50 million or (y) all remaining Registrable Securities held by the Demanding Investor, then notwithstanding the time

C-168

periods provided for in Section 2.1.4, such Demanding Investor need only to notify the Company of the Block Trade at least five (5) business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Block Trade; provided that the Demanding Investors representing a majority of the Registrable Securities wishing to engage in the Block Trade shall use reasonable best efforts to work with the Company and any Underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade.

2.4.2 Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade, a majority-in-interest of the Demanding Investors initiating such Block Trade shall have the right to submit a Withdrawal Notice to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade prior to its withdrawal under this Section 2.4.2.

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (or such shorter period of time as may be necessary in order to comply with the Securities Act, the Exchange Act, and the rules and regulations promulgated under the Securities Act or Exchange Act, as applicable), furnish a copy thereof to each seller of such Registrable Securities or its counsel (excluding any exhibits thereto and any filing made under the Exchange Act that is to be incorporated by reference therein);

3.1.9 notify the Investors at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

3.1.10 permit a representative of the Investors, the Underwriters, if any, and any attorney or accountant retained by such Investors or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriters agree to confidentiality arrangements reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.11 obtain a “comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, in customary form and covering such matters of the type customarily covered by “comfort” letters as the managing Underwriter or other similar type of sales agent or placement agent may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Investors;

legal matters with respect to the Registration in respect of which such opinion is being given as the Investors, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority-in-interest of the participating Investors;

3.1.13 in the event of any Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, enter into and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary form, with the managing Underwriter, sales agent or placement agent of such offering;

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investors, in connection with such Registration.

Notwithstanding the foregoing, the Company shall not be required to provide any documents or information to an Underwriter or other sales agent or placement agent if such Underwriter or other sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Investors that the Investors shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ or agents’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Investors.

3.3 Requirements for Participation in Registration Statement Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Investor does not provide the Company with its requested Investor Information, the Company may exclude such Investor’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the registration and such Investor continues thereafter to withhold such information. No person may participate in any Underwritten Offering or other coordinated offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such arrangements. The exclusion of an Investor’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Investors shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being

C-171

understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.4.2 If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the majority of the Board such Registration, be seriously detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Investors, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.4.2, the Investors agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

3.4.3 (a) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated Registration and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf Registration Statement, or (b) if, pursuant to Section 2.1.4, Investors have requested an Underwritten Shelf Takedown and the Company and such Investors are unable to obtain the commitment of underwriters to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Investors, delay any other registered offering pursuant to Section 2.1.4 or 2.4. Notwithstanding anything to the contrary contained in this Agreement and except for the obligations set forth in Section 2.1.1 and Section 2.2.2, no Registration shall be effected or permitted, no Registration Statement shall become effective, and no notice shall be refused to be delivered with respect to any Registrable Securities held by any Investor, until after the expiration of the Lock-Up Period applicable to the securities.

3.5 Reporting Obligations. As long as any Investor shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Investors with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Investors pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Investor may reasonably request, all to the extent required from time to time to enable such Investor to sell shares of Common Stock held by such Investor without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Investor, the Company shall deliver to such Investor a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Investor of Registrable Securities, its officers, directors and agents and each person who controls such Investor (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without

C-172

limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Investor expressly for use therein.

4.1.2 In connection with any Registration Statement in which an Investor of Registrable Securities is participating, such Investor shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Investor Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Investor expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Investors of Registrable Securities, and the liability of each such Investor of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Securities pursuant to such Registration Statement. The Investors of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Investor of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Investor’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the

C-173

indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Investor under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Investor in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

The Attribute Schedule shall also list any limitations on the ability of the Corporation to utilize any Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets under applicable laws (including as a result of the operation of Section 382 of the Code or Section 383 of the Code).

Section 2.2. Tax Benefit Schedule.

(a) Tax Benefit Schedule. Following the Closing Date, within ninety (90) calendar days after the filing of the Form 1120 (or any successor form) of the Corporation for any Taxable Year, the Corporation shall provide

C-195

to the TRA Party Representative a schedule showing, in reasonable detail, the calculation of the Tax Benefit Payment in respect of each TRA Party for such Taxable Year and the calculation of the Realized Tax Benefit and Realized Tax Detriment and the components thereof for such Taxable Year (a “Tax Benefit Schedule”). Each Tax Benefit Schedule will become final as provided in Section 2.3(a) and may be amended as provided in Section 2.3(b) (subject to the procedures set forth in Section 2.3(b)).

(b) Applicable Principles. For purposes of calculating the Realized Tax Benefit or Realized Tax Detriment for any period, carryovers or carrybacks of any Tax item attributable to the Blocker Pre-BCA Covered Tax Assets and the Exchange Covered Tax Assets shall be considered to be subject to the rules of the Code and the Treasury Regulations, as applicable, or other applicable law, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type.

Section 2.3. Procedures, Amendments.

(a) Procedure. Every time the Corporation delivers to the TRA Party Representative a Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.3(b), and any Early Termination Schedule or amended Early Termination Schedule, the Corporation shall also deliver schedules, valuation reports, if any, and work papers, as determined by the Corporation or reasonably requested by the TRA Party Representative, providing reasonable detail regarding the preparation of the Schedule, and allow the TRA Party Representative reasonable access at no cost to the appropriate representatives of the Corporation, as determined by the Corporation or requested by the TRA Party Representative, in connection with the review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporation delivers to the TRA Party Representative a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporation shall also deliver to the TRA Party Representative a reasonably detailed calculation of the applicable Hypothetical Tax Liability, a reasonably detailed calculation of the applicable Actual Tax Liability, as well as any other work papers considered relevant by the Corporation or requested by the TRA Party Representative, provided that the Corporation shall not be required to provide any information that it reasonably believes is unnecessary for purposes of determining the items in the applicable Schedule or amendment thereto. Subject to Section 2.3(b), an applicable Schedule or amendment thereto shall become final and binding on all parties thirty (30) calendar days after the first date on which the TRA Party Representative has received the applicable Schedule or amendment thereto unless (i) the TRA Party Representative provides the Corporation before such date with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) the TRA Party Representative provides a written waiver of such right of any Objection Notice before such date (in which case such Schedule or amendment thereto becomes binding on the date such waiver has been received by the Corporation). If the Corporation and the TRA Party Representative, for any reason, are unable to successfully resolve the issues raised in an Objection Notice within thirty (30) calendar days after receipt by the Corporation of an Objection Notice, then the Corporation and the TRA Party Representative shall employ the reconciliation procedures described in Section 7.8 of this Agreement (the “Reconciliation Procedures”).

(b) Amended Schedule. The applicable Attribute Schedule or Tax Benefit Schedule for any Taxable Year may be amended from time to time by the Corporation (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified after the date the Schedule was provided to the TRA Party Representative, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, or (v) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year (any such Schedule, an “Amended Schedule”). The Corporation shall provide to the TRA Party Representative an Amended Schedule, along with reasonable detail regarding the preparation of the applicable portion of such Amended Schedule, within sixty (60) calendar days of the occurrence of an event referenced in clauses (i) through (v) of the first sentence of this Section 2.3(b).

C-196

ARTICLE III.

TAX BENEFIT PAYMENTS

Section 3.1. Timing and Amount of Tax Benefit Payments.

(a) Within five (5) Business Days after a Tax Benefit Schedule delivered to the TRA Party Representative becomes final in accordance with Section 2.3(a), the Corporation shall pay or cause to be paid to each TRA Party for such Taxable Year an amount equal to the excess, if any, of (i) the Tax Benefit Payment in respect of such TRA Party for such Taxable Year determined pursuant to Section 3.1(b) over (ii) the aggregate amount of Advance Payments previously made to such TRA Party in respect of such Taxable Year; provided that, if the Corporation makes Advance Payments, it shall make Advance Payments to all parties eligible to receive payments under this Agreement with respect to a particular Taxable Year in proportion to their respective amount of anticipated payments under this Agreement in respect of such Taxable Year. Each such Tax Benefit Payment or such Advance Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such TRA Party to the Corporation or as otherwise agreed by the Corporation and such TRA Party. The Corporation shall use its commercially reasonable efforts to respond to any reasonable inquiry of a TRA Party in regard to the calculation of the amount payable to such TRA Party pursuant to any Schedule delivered under this Agreement, including the calculation of the Tax Benefit Payment in respect of such TRA Party for such Taxable Year.

(b) A “Tax Benefit Payment” in respect of a TRA Party means an amount, not less than zero, equal to the sum of the portion of the Net Tax Benefit that is Attributable to such TRA Party and the Interest Amount with respect thereto. A Net Tax Benefit is “Attributable” to a Blocker TRA Party to the extent that it is derived from a Blocker Pre-BCA Covered Tax Asset with respect to a Blocker. A Net Tax Benefit is “Attributable” to an Exchange TRA Party to the extent that it is derived from an Exchange Covered Tax Asset with respect to Company Units that were Exchanged by such TRA Party. The “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the sum of the total amount of payments previously made under Section 3.1(a) (excluding payments attributable to Interest Amounts) and the Advance Payments previously made under Section 3.1(b) of this Agreement (excluding any portion of Advance Payments in respect of anticipated Interest Amounts); provided, for the avoidance of doubt, that a TRA Party shall not be required to return any portion of any previously made Tax Benefit Payment or Advance Payment it receives under this Agreement. The “Interest Amount” in respect of the TRA Party shall equal the interest on the amount of the unpaid Net Tax Benefit Attributable to such TRA Party for a Taxable Year, which interest shall accrue on any unpaid Net Tax Benefit from and after the due date (without extensions) for filing the IRS Form 1120 (or any successor form) for the Corporation for such Taxable Year, calculated at the Agreed Rate, until the date such unpaid amounts are paid. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but instead shall be treated as additional consideration in the Business Combination or an Exchange, as applicable, unless otherwise required by law. “Advance Payments” in respect of a TRA Party for a Taxable Year means the payments made by the Corporation to such TRA Party as an advance of such TRA Party’s anticipated Tax Benefit Payment for such Taxable Year. The Corporation shall be entitled at its option with the approval of a majority of the Independent Directors to make Advance Payments. Notwithstanding anything to the contrary in this Agreement, after any lump-sum payment under Article IV of this Agreement in respect of present or future Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets, such Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets shall no longer be considered Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets, as applicable, for purposes of determining Tax Benefit Payments or the Net Tax Benefit.

Section 3.2 No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed consistent with such intent.

C-197

Section 3.3. Pro Rata Payments.

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate amount of the tax benefit to the Corporation from the reduction in Tax liability as a result of the Blocker Pre-BCA Covered Tax Assets or the Exchange Covered Tax Assets is limited in a particular Taxable Year because the Corporation does not have sufficient taxable income to fully utilize available deductions and other attributes, the aggregate Net Tax Benefit for such Taxable Year shall be deemed Attributable to each TRA Party for purposes of Section 3.1(b) in proportion to the portion of such Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) if the Corporation had sufficient taxable income so that there were no such limitation; provided, that, for the avoidance of doubt, for purposes of allocating among the TRA Parties the aggregate Net Tax Benefit with respect to any Taxable Year, the operation of this Section 3.3(a) with respect to any prior Taxable Years shall be taken into account so as to eliminate as quickly as possible, proportionately, the difference with respect to each TRA Party between (i) the aggregate Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) if the Corporation had sufficient taxable income so that there were no limitation under this Section 3.3(a) and (ii) the actual aggregate Net Tax Benefit deemed Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) by operation of this this Section 3.3(a). Consistent with the foregoing, the Attribute Schedule for a given Taxable Year shall reflect the operation of this Section 3.3(a) in respect of previous Taxable Years, with the Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets described in such Attribute Schedule that are Attributable to a TRA Party being adjusted to reflect payments received in respect of such Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets (the intention of the parties being to avoid duplicative payments and maintain records sufficient to allow the Corporation to allocate Tax Benefit Payments consistent with the terms of this Section 3.3(a)).

(b) After taking into account Section 3.3(a), if for any reason the Corporation does not fully satisfy its payment obligations to make Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year (for example, as a result of having insufficient cash to make the Tax Benefit Payments due hereunder), then the Corporation and the TRA Parties agree that (i) the Corporation shall make payments due hereunder to the TRA Parties in respect of a Taxable Year in the same proportion as such payments would have been made if the relevant payment had been made in full by the Corporation, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been paid.

(c) To the extent the Corporation makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account Sections 3.3(a) and (b)) in an amount in excess of the amount of such payment that should have been made to the TRA Party in respect of such Taxable Year, then (i) the TRA Party shall not receive further payments under Section 3.1(a) until the TRA Party has forgone an amount of payments equal to such excess and (ii) the Corporation shall pay the amount of the TRA Party’s forgone payments to other TRA Parties (to the extent applicable) in a manner such that each of the other TRA Parties, to the extent possible, shall have received aggregate payments under Sections 3.1(a) and (b) in the amount it would have received if there had been no excess payment to the TRA Party.

Section 3.4. Withholding. The Corporation and its affiliates and representatives shall be entitled to deduct and withhold from any payment that is payable to any TRA Party pursuant to this Agreement such amounts as are required to be deducted or withheld with respect to the making of such payment in accordance with the Code or any provision of U.S. state, local or foreign tax law (including for this purpose any withholding required by the Corporation or its affiliates that may be required in connection with an Exchange). To the extent that amounts are so deducted or withheld and promptly paid over to the appropriate Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid by the Corporation to the relevant TRA Party. The Corporation shall provide evidence of such payment to each TRA Party in respect of which such deduction or withholding is required, to the extent that such evidence is available. Each TRA Party shall promptly provide the Corporation with any applicable tax forms and certifications reasonably requested by the Corporation in connection with determining whether any such deductions and withholdings are required under the Code or any

C-198

provision of U.S. state, local or foreign tax law. The Corporation will consider in good faith any applicable certificates, forms or documentation provided by a TRA Party that in such TRA Party’s reasonable determination reduce or eliminate any such withholding.

ARTICLE IV.

TERMINATION

Section 4.1. Early Termination of Agreement; Breach of Agreement.

(a) With the prior written approval of the Board (or any Person(s) to whom the Board has delegated such authority), the Corporation may terminate this Agreement with respect to all amounts payable to the TRA Parties at any time by paying to each TRA Party the Early Termination Payment in respect of the TRA Party; provided, however, that (i) this Agreement shall only terminate pursuant to this Section 4.1(a) upon the receipt in full of the Early Termination Payment by the TRA Parties, (ii) the Corporation shall deliver an Early Termination Notice only if it is able to make all required Early Termination Payments under this Agreement, and (iii) the Corporation may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid.

(b) In the event that the Corporation breaches any of its material obligations under this Agreement, whether as a result of a failure to make any payment when due, a failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, and the Corporation fails to cure such breach within 20 Business Days of the TRA Party Representative informing the Corporation of such breach, then, at the election of the TRA Party Representative, all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach. Procedures similar to the procedures of Section 4.2 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation pursuant to this Section 4.1(b). Notwithstanding the foregoing, in the event that the Corporation breaches any of its material obligations under this Agreement, the TRA Party Representative shall be entitled to elect on behalf of all TRA Parties to receive the amounts referred to in this Section 4.1(b) or to seek specific performance of the terms of this Agreement. The parties agree that the failure to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3) months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of a material obligation of this Agreement if the Corporation fails to make any Tax Benefit Payment when due to the extent that the Corporation has insufficient funds to make such payment; provided, (i) the Corporation has used reasonable efforts to obtain such funds (including by causing the Company or any other Subsidiaries of the Company to distribute or lend funds to facilitate such payment, and by accessing any revolving credit facilities or other sources of available credit to fund any such amounts) and (ii) that the interest provisions of Section 5.3 shall apply to such late payment (unless the Corporation does not have sufficient funds to make such payment as a result of limitations imposed by any Senior Obligations, in which case Section 5.3 shall apply, but the Default Rate shall be replaced by the Agreed Rate).

(c) In connection with a Change of Control, all obligations under this Agreement with respect to the applicable TRA Parties shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the closing date of the Change of Control. Section 4.2 and Section 4.3 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation.

Section 4.2. Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1(a) above, the Corporation shall deliver to the TRA Party Representative written notice of such intention to exercise such right (“Early Termination Notice”). In addition, if the Corporation chooses to exercise

C-199

its right of early termination under Section 4.1(a) above, or the obligations under this Agreement are accelerated under Section 4.1(b) or Section 4.1(c) above, the Corporation shall deliver to the TRA Party Representative a schedule (the “Early Termination Schedule”) showing in reasonable detail the calculation of the Early Termination Payment due to each TRA Party. Such Early Termination Schedule shall become final and binding on all parties consistent with the procedures described in Section 2.3(a). The date on which the Early Termination Schedule becomes final shall be the “Early Termination Effective Date.”

Section 4.3. Payment upon Early Termination.

(a) Within three (3) calendar days after an Early Termination Effective Date, the Corporation shall pay to the TRA Parties an amount equal to the Early Termination Payment in respect of such TRA Party; provided, however, that any amount payable pursuant to this Agreement as a result of a Change of Control shall be paid concurrently with the consummation of such Change of Control. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the TRA Party or as otherwise agreed by the Corporation and such TRA Party.

(b) “Early Termination Payment” in respect of a TRA Party shall equal (i) the present value, discounted at the Early Termination Rate, as of the date of the Early Termination Notice, of all Tax Benefit Payments in respect of such TRA Party that would be required to be paid by the Corporation beginning from the date of the Early Termination Notice and assuming that the Valuation Assumptions in respect of such TRA Party are applied and that each such Tax Benefit Payment for each relevant Taxable Year would be paid on the due date (including extensions) under applicable law as of the Early Termination Date for filing of IRS Form 1120 (or any successor form) of the Corporation for each such Taxable Year, plus (ii) any Tax Benefit Payment due and payable with respect to such TRA Party that is unpaid as of the date of the Early Termination Notice.

(c) Upon the payment of the Early Termination Payment by the Corporation to a TRA Party, the Corporation shall not have any further payment obligations under this Agreement in respect of such TRA Party.

ARTICLE V.

SUBORDINATION; CERTAIN TAX COVENANTS; LATE PAYMENTS

Section 5.1. Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment or Early Termination Payment required to be made by the Corporation under this Agreement shall rank subordinate and junior in right of payment to any principal, interest, or other amounts due and payable in respect of any obligations owed in respect of secured or unsecured indebtedness for borrowed money of the Corporation and its Subsidiaries (“Senior Obligations”) and shall rank pari passu in right of payment with all current or future unsecured obligations of the Corporation that are not Senior Obligations. To the extent that any payment under this Agreement is not permitted to be made at the time payment is due as a result of this Section 5.1 and the terms of the agreements governing Senior Obligations, such payment obligation nevertheless shall accrue for the benefit of the applicable TRA Parties and the Corporation shall make such payments at the first opportunity that such payments are permitted to be made in accordance with the terms of the Senior Obligations (it being understood that interest shall accrue on the amount of such unpaid obligation in accordance with the terms hereof). Payments under any tax receivable agreement or similar agreement (excluding, for the avoidance of doubt, this Agreement) entered into after the date hereof or as part of any transaction entered into after the date hereof in which the Corporation, the Company or their Subsidiaries would be required to pay the parties thereto for tax attributes shall be subordinate to all payments owed pursuant to this Agreement, and no such payments shall be made for so long as the Corporation has any current unpaid obligation pursuant this Agreement. The Corporation shall use its commercially reasonable efforts to maintain sufficient available funds for the purpose of making required payments under this Agreement and avoid entering into credit agreements or Senior Obligations that could be reasonably anticipated to materially delay the timing of any payments under this Agreement.

Section 5.2. Certain Tax Covenants.

(a) The Corporation hereby agrees and warrants to each TRA Party (i) that it will not cause the Company or any material Subsidiary of the Company to convert into, or elect to be treated as, a corporation for Tax purposes without the prior written consent of the TRA Party Representative, (ii) that it will not cause the Company to contribute any of its material assets into one or more Subsidiaries that are treated as corporations for Tax purposes, or cause the Company to liquidate or distribute in kind any of its material non-cash assets to its members, without the prior written consent of the TRA Party Representative, and (iii) that it will cause the Company, and any material Subsidiary that is treated as a partnership for Tax purposes, to make valid Section 754 elections (and all comparable elections under applicable state and local tax law) for its first Taxable Year ending after the date of this Agreement and it will not seek to revoke any such election until the Corporation has received all material tax benefits from all Exchange Party Basis Adjustments and Imputed Interest in respect of which the Corporation may be required to make any payments under this Agreement to the TRA Parties.

(b) The Corporation hereby agrees that prior to (i) any proposed Interest Sale (as defined in Section 5.2(c)) or (ii) any proposed sale or other disposition of all or any substantial part of the non-cash assets of the Company, it shall deliver to each TRA Party notice of such proposed transaction at least thirty (30) days prior to the consummation thereof and afford each TRA Party that still holds Company Units the opportunity to Exchange all or part of such Company Units prior to such date.

(c) For purposes of this Agreement, (i) any sale or other disposition of all or any part of the Corporation’s interest in the Company (an “Interest Sale”) shall be deemed to be comprised of a sale or other disposition of a pro rata portion of each of the separate interests held by the Corporation (i.e., the original interest of the Corporation as of the date of this Agreement and each additional interest acquired hereafter by Exchange or otherwise), regardless of whether such separate interests can be (or are) identified and separately conveyed, and (ii) notwithstanding any provision herein to the contrary, for purposes of determining the payments due to the TRA Parties hereunder attributable to such Interest Sale, each such separate interest that was acquired from a TRA Party pursuant to an Exchange shall be treated as a Reference Asset and the Exchange Party Basis Adjustment with respect thereto shall be the excess of the tax basis of the Corporation in such interest immediately after such Exchange over the tax basis of such TRA Party in the applicable Company Units immediately before such Exchange (with such Exchange Party Basis Adjustment to be increased as appropriate to reflect payments by the Corporation to such TRA Party pursuant to this Agreement and to be decreased as appropriate to reflect the depreciation or amortization attributable to the correlative Exchange Party Basis Adjustments to the underlying assets of the Company).

Section 5.3. Late Payments by the Corporation. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment or other payment under this Agreement not made to the TRA Parties when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment, Early Termination Payment or other payment was due and payable.

ARTICLE VI.

TAX MATTERS; CONSISTENCY; COOPERATION

Section 6.1. Participation in the Corporation’s and the Company’s Tax Matters. Except as otherwise provided in this Agreement, the Business Combination Agreement or the Company LLC Agreement, the Corporation shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporation, the Company and their Subsidiaries, including the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing,

(i) the Corporation shall notify the TRA Party Representative in writing of the commencement of, and keep the TRA Party Representative reasonably informed with respect to, the portion of any audit of the

C-201

Corporation, the Company or any of their Subsidiaries by a Taxing Authority the outcome of which would reasonably be expected to materially affect the rights and obligations of a TRA Party under this Agreement, including the Tax Benefit Payments payable to TRA Parties,

(ii) shall provide to the TRA Party Representative reasonable opportunity (at the cost and expense of the TRA Party Representative, on behalf of the TRA Parties) to participate in or provide information and other input to the Corporation, the Company and their Subsidiaries, as applicable, and their respective advisors concerning the conduct of any such portion of such audit, which the Corporation, the Company and their Subsidiaries (including their advisors) shall consider in good faith; and

(iii) the Corporation, the Company and their Subsidiaries, as applicable, shall not enter into any settlement with respect to any such portion of such audit that could have a material adverse effect on the TRA Parties’ rights to receive payments under this Agreement without the written consent of the TRA Party Representative, such consent not to be unreasonably withheld, conditioned or delayed.

Section 6.2. Reconciliation. In the event that the Corporation and the TRA Party Representative are unable to resolve a disagreement with respect to a Schedule (a “Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to such parties. The Expert shall be a partner or principal in a nationally recognized accounting firm. If the Corporation and the TRA Party Representative are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the selection of an Expert shall be treated as a dispute subject to Section 7.8 and an arbitration panel shall pick an Expert. The Expert shall resolve any matter relating to a Schedule or an amendment thereto as soon as reasonably practicable and in any event within thirty (30) calendar days after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporation, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporation except as provided in the next sentence. The Corporation and the TRA Party Representative shall bear their own costs and expenses of such proceeding, unless (i) the Expert entirely adopts the position of the TRA Party Representative, in which case the Corporation shall reimburse the TRA Party Representative for any reasonable and documented out-of-pocket costs and expenses in such proceeding, or (ii) the Expert entirely adopts the Corporation’s position, in which case Tax Benefit Payments to the TRA Parties that would have increased Tax Benefit Payments if the position of the TRA Party Representative had been adopted shall be reduced proportionately in the aggregate by any reasonable and documented out-of-pocket costs and expenses in such proceeding. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 6.2 shall be binding on the Corporation and the TRA Parties and may be entered and enforced in any court having competent jurisdiction.

Section 6.3. Consistency. The Corporation and the TRA Parties agree to report and cause to be reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related items (including, without limitation, the Exchange Party Basis Adjustments, Blocker Party Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that specified in any Schedule finalized consistent with the terms of this Agreement, unless otherwise required by a contrary Determination by an applicable Taxing Authority.

Section 6.4. Cooperation. Each of the Corporation, the Company and the TRA Parties shall (a) furnish to the other parties in a timely manner such information, documents and other materials as the other party may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or defending any audit, examination or controversy with any Taxing Authority, (b) make itself reasonably available to the other parties and their respective representatives to provide explanations of documents and material and such other information as the other party or its representatives may

C-202

reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and the Corporation shall reimburse each TRA Party for any reasonable third-party costs and expenses incurred pursuant to this Section 6.4 at the request of the Corporation or the Company.

Section 6.5. Tax Characterization. The parties intend that (a) each Exchange shall give rise to Exchange Party Basis Adjustments and (b) payments to Exchange TRA Parties pursuant to this Agreement with respect to an Exchange (except with respect to amounts that constitute Imputed Interest) shall be treated as consideration in respect of such Exchange that give rise to additional Exchange Party Basis Adjustments.

Section 6.6. Change in Tax Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in Tax law, a TRA Party reasonably believes that the existence of this Agreement could increase the amount of income (other than income arising from receipt of a payment under this Agreement) recognized by such TRA Party upon any Exchange which is treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income and all applicable state and local Tax purposes or would have other material adverse Tax consequences to the TRA Party and/or its direct or indirect owners, then at the election of such TRA Party and to the extent specified by the TRA Party, this Agreement (i) shall cease to have further effect with respect to such TRA Party, (ii) shall not apply to an Exchange by the TRA Party occurring after a date specified by it, or (iii) shall otherwise be amended in a manner determined by the TRA Party to waive any benefits to which such TRA Party would otherwise be entitled under this Agreement, provided that such amendment shall not result in an increase in or acceleration of payments under this Agreement at any time as compared to the amounts and times of payments that would have been due in the absence of such amendment or increase the Corporation’s administrative burden in complying with this Agreement.

Delivery of an executed signature page to this Agreement by facsimile transmission or electronic mail shall be as effective as delivery of a manually signed counterpart of this Agreement.

Section 7.3. Entire Agreement; No Third Party Beneficiaries. This Agreement constitutes the entire agreement and supersedes all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter hereof. This Agreement shall be binding upon and inure solely to the benefit of each Party hereto and their respective successors and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

Section 7.4. Governing Law. This Agreement and its enforcement and any controversy arising out of or relating to the making or performance of this Agreement shall be governed by, and construed in accordance with, the law of the State of Delaware, without regard to the conflicts of laws principles thereof that would mandate the application of the laws of another jurisdiction.

Section 7.5. Severability. If any term or other provision of this Agreement, or the application of such term or provision to any Person or circumstance or in any jurisdiction, is invalid, illegal or incapable of being enforced, to any extent, by any law or public policy, all other terms and provisions of this Agreement shall nevertheless remain in full force and effect to the fullest extent permitted by law. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, such term or provision is hereby deemed modified to give effect to the original written intent of the parties to the greatest extent consistent with being valid and enforceable under applicable law. No party hereto shall assert, and each party shall cause its Affiliates or related parties not to assert, that this Agreement or any part hereof is invalid, illegal or unenforceable.

Section 7.6. Assignments; Amendments; Successors; No Waiver.

(a) Assignment. No TRA Party is permitted to assign, sell, transfer, pledge, delegate, or otherwise dispose of any interest, right or obligation under this Agreement without the prior written approval of the Board (not to be unreasonably withheld, conditioned or delayed); provided, that to the extent Company Units are transferred in accordance with the terms of the Company LLC Agreement, the transferring TRA Party shall

C-204

assign to the transferee of such Company Units the transferring TRA Party’s rights under this Agreement as long as such transferee has executed and delivered or, in connection with such transfer, executes and delivers, a Joinder agreeing to become a “TRA Party” for all purposes of this Agreement.

(b) Amendments. No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporation and by TRA Parties who would be entitled to receive more than fifty percent (50%) of the aggregate amount of the Early Termination Payments payable to all TRA Parties hereunder if the Corporation had exercised its right of Early Termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Party pursuant to this Agreement since the date of such most recent Exchange); provided, however, that no such amendment shall be effective if such amendment would have a disproportionate effect on the payments certain TRA Parties will or may receive under this Agreement unless all such disproportionately affected TRA Parties consent in writing to such amendment; provided, further, that amendment of the definition of Change of Control or any approval rights granted to the Independent Directors will also require the written approval of a majority of the Independent Directors.

(c) Successors. Except as provided in Section 7.6(a), all of the terms and provisions of this Agreement shall be binding upon, and shall inure to the benefit of and be enforceable by, the parties hereto and their respective successors, permitted assigns, heirs, executors, administrators and legal representatives. The Corporation shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place.

(d) Waiver. Neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No party shall be deemed to have waived any claim arising out of this Agreement, or any right, remedy, power or privilege under this Agreement, unless the waiver of such claim, right, remedy, power or privilege is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 7.7. Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

Section 7.8. Resolution of Disputes.

(a) Any and all disputes which cannot be settled amicably after good faith negotiations, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in the state of Delaware in accordance with the then-existing Rules of Arbitration of the International Chamber of Commerce. If the parties to the dispute fail to agree on the selection of an arbitrator within ten (10) calendar days of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b) Notwithstanding the provisions of Section 7.8(a), the Corporation and the TRA Party Representative may bring an action or special proceeding in any court of competent jurisdiction for the purpose of compelling another party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration

C-205

hereunder, and/or enforcing an arbitration award and, for the purposes of this Section 7.8(b), each TRA Party (i) expressly consents to the application of Section 7.8(b) to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporation as each TRA Party’s agent for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise such TRA Party of any such service of process, shall be deemed in every respect effective service of process upon such TRA Party in any such action or proceeding.

(c)          (i) EACH TRA PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN THE STATE OF DELAWARE FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF SECTION 7.8(B), OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the forum designated by this Section 7.8(c) has a reasonable relation to this Agreement, and to the parties’ relationship with one another.

        (ii) The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in Section 7.8(c)(i) of this Section 7.8 and such parties agree not to plead or claim the same.

Section 7.9. Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER OR RELATE TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE BREACH OR VALIDITY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ACTION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.9.

Section 7.10. Confidentiality. Each TRA Party and its assignees acknowledges and agrees that the information of the Corporation and its Affiliates provided pursuant to this Agreement is confidential and, except in the course of performing any duties as necessary for the Corporation and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such Person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters of the Corporation and its Affiliates and successors acquired pursuant to this Agreement. This Section 7.10 shall not apply to (i) any information that has been made publicly available by the Corporation, becomes public knowledge (except as a result of an act of any TRA Party in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to the extent necessary for a TRA Party to prosecute or defend claims arising under or relating to this Agreement, (iii) the disclosure of information to the extent necessary for a TRA Party to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such Tax Returns, and (iv) the disclosure to any potential assignee or transferee of information in connection with an assignment, sale, pledge, alienation or

C-206

transfer of any interest in this Agreement pursuant to Section 7.6(a) so long as such potential assignee or transferee agrees to be subject to the provisions of this Section 7.10. Notwithstanding anything to the contrary in this Agreement, to the extent required by applicable law or to the extent reasonably necessary for a TRA Party to comply with any applicable reportable transaction requirements under applicable law, each TRA Party (and each employee, representative or other agent of the TRA Party, as applicable) may disclose the Tax treatment and Tax structure of the Corporation, the Company and their Subsidiaries, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that are provided to the TRA Party relating to such Tax treatment and Tax structure.

Section 7.11. Interest Rate Limitation. Notwithstanding anything to the contrary contained herein, the interest paid or agreed to be paid hereunder with respect to amounts due to any TRA Party hereunder shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If any TRA Party shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the Tax Benefit Payment, Advance Payment or Early Termination Payment, as applicable (but in each case exclusive of any component thereof comprising interest) or, if it exceeds such unpaid non-interest amount, refunded to the Corporation. In determining whether the interest contracted for, charged, or received by any TRA Party exceeds the Maximum Rate, such TRA Party may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the payment obligations owed by the Corporation to such TRA Party hereunder. Notwithstanding the foregoing, it is the intention of the parties hereto to conform strictly to any applicable usury laws.

Section 7.12. Independent Nature of Rights and Obligations.

(a) The rights and obligations of the each TRA Party hereunder are several and not joint with the rights and obligations of any other Person. A TRA Party shall not be responsible in any way for the performance of the obligations of any other Person hereunder, nor shall a TRA Party have the right to enforce the rights or obligations of any other Person hereunder (other than the Corporation). Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any TRA Party pursuant hereto or thereto, shall be deemed to constitute the TRA Parties acting as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the TRA Parties are in any way acting in concert or as a group with respect to such rights or obligations or the transactions contemplated hereby, and the Corporation acknowledges that the TRA Parties are not acting in concert or as a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated hereby.

(b) Except as otherwise explicitly provided in this Agreement, the actions of a TRA Party pursuant to and in accordance with this Agreement shall be binding only with respect to such TRA Party and not with respect to the any other TRA Party. To the fullest extent permitted by law, no TRA Party shall owe any duties (fiduciary or otherwise) to any other TRA Party or any other Person in determining to take or refrain from taking any action or decision under or in connection with this Agreement.

(c) Tax Distributions.

(i) With respect to each Fiscal Year or portion thereof ending after the Effective Date, the Company shall, to the extent permitted by applicable Law, make cash distributions (“Tax Distributions”) to each Member in an amount to ensure that each such Member receives a distribution at least equal to such Member’s Assumed Tax Liability, if any, with respect to the relevant taxable period to which the distribution relates. For the avoidance of doubt, such Tax Distributions shall be determined in accordance with Section 4.01(c)(ii). Tax Distributions pursuant to this Section 4.1(c)(i) shall be estimated by the Company on a quarterly basis and, to the extent feasible, shall be distributed to the Members (together with a statement showing the calculation of such Tax Distribution and an estimate of the Company’s net taxable income allocable to each Member for such period) on a quarterly basis five business days prior to April 15th, June 15th, September 15th and January 15th (of the succeeding year) (or such other dates for which individuals are required to make quarterly estimated tax payments for U.S. federal income tax purposes) (each, a “Quarterly Tax Distribution”); provided, that the foregoing shall not restrict the Company from making a Tax Distribution on any other date. Quarterly Tax Distributions shall take into account the estimated taxable income or loss of the Company for the Fiscal Year through the end of the relevant quarterly period. A final accounting for Tax Distributions shall be made for each Fiscal Year after the allocation of the Company’s actual net taxable income or loss has been determined and any shortfall in the amount of Tax Distributions a Member received for such Fiscal Year based on such final accounting shall promptly be distributed to such Member. For the avoidance of doubt, any excess Tax Distributions a Member receives with respect to any Fiscal Year shall reduce future Tax Distributions otherwise required to be made to such Member with respect to any subsequent Fiscal Year.

(ii) A Tax Distribution to a Member in respect of any Unit shall be charged against current or future distributions to which such Member would otherwise have been entitled under Section 4.01(a) or Section 9.03(c) in respect of such Unit; provided, however, that all Units shall participate in distributions made pursuant to this Section 4.01(c) on a pro rata basis. Notwithstanding the foregoing, (A) any distributions made pursuant to this Section 4.01(c) shall be made to the Members on a pro rata basis, (B) to the extent of Available Cash, the pro rata amount to be distributed to each Member shall be calculated based on the distribution to the Member that would have the highest Tax Distribution under this Section 4.01(c) on a per-Unit basis, calculated without regard to this sentence and (C) if there is insufficient Available Cash to make all of the distributions described in clause (B), the amount that would have been distributed to each Member pursuant to clause (B) shall be reduced on a pro rata basis and the Company shall make future Tax Distributions as soon as there is sufficient Available Cash to pay the remaining portion of the Tax Distributions to which such Members were otherwise entitled under clause (B).

(iii) In the event of any audit by a taxing authority that has been finally settled and as such, affects the calculation of any Member’s Assumed Tax Liability for any taxable year (other than an audit conducted pursuant to the Partnership Audit Provisions for which no election is made pursuant to Section 6226 thereof and the Treasury Regulations promulgated thereunder), or in the event the Company files an amended tax return, each Member’s Assumed Tax Liability with respect to such year shall be recalculated by giving effect to such event (for the avoidance of doubt, taking into account interest or penalties). Any shortfall in the amount of Tax Distributions the Members and former Members received for the relevant taxable years based on such recalculated Assumed Tax Liability promptly shall be distributed to such Members and the successors of such former Members, except, for the avoidance of doubt, to the extent Distributions were made to such Members and former Members pursuant to Section 4.01(a) and this Section 4.01(c) in the relevant taxable years sufficient to cover such shortfall.

C-227

(d) Notwithstanding anything to the contrary set forth herein, the Managing Member shall cause any distributions paid to any Subsidiary of the Managing Member who holds Units to distribute the full amount of such distribution to the Managing Member, and the Managing Member shall take all actions necessary to cause such distributions.

Section 4.03. Limitations on Distribution.

This Section 5.05(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

Any special allocations of income or gain pursuant to Sections 5.05(b) or 5.05(c) hereof shall be taken into account in computing subsequent allocations pursuant to Section 5.04 and this Section 5.05(f), so that the net amount of any items so allocated and all other items allocated to each Member shall, to the extent possible, be equal to the net amount that would have been allocated to each Member if such allocations pursuant to Sections 5.05(b) or 5.05(c) had not occurred.

C-229

(g) Notwithstanding anything to the contrary contained in this Agreement, (1) no allocation (of Profits or Losses or otherwise) shall be made in respect of any Earnout Units in determining Capital Accounts unless and until such Units are vested upon the occurrence of an Earnout Vesting Event, if any, and (2) in the event the Carrying Value of any Company asset is adjusted pursuant to clause (d) of the definition of Carrying Value, any Profits or Losses resulting from such adjustment shall, in the manner reasonably determined by the Managing Member, be allocated among the Members such that the Capital Account balance relating to each Class A Unit (excluding any Unvested Earnout Units) is equal in amount immediately after making such allocation, after taking into account the non-distribution amounts (as applicable) in accordance with principles similar to those set forth in Treasury Regulations Section 1.704- 1(b)(2)(iv)(s); provided, that if the foregoing allocations pursuant to clause (2) are insufficient to cause the Capital Account balance relating to each Class A Unit to be so equal in amount, then the Managing Member, in its reasonable discretion, shall cause a Capital Account reallocation in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(3) to cause the Capital Account balance relating to each Class A Unit to be so equal in amount.

Section 5.06. Tax Allocations. For U.S. federal income tax purposes, each item of income, gain, loss and deduction of the Company shall be allocated among the Members in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that in the case of any asset the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated, solely for income tax purposes, to account for such difference using the “traditional method” without curative allocations under Treasury Regulations Section 1.704-3(b).

Section 5.07. Tax Advances. To the extent the Managing Member reasonably believes that the Company is required by law to withhold or to make tax payments on behalf of or with respect to any Member, or the Company is subjected to tax itself by reason of the status of any Member (including any taxes paid pursuant to Section 6225 of the Code) (“Tax Advances”), the Managing Member may cause the Company to withhold such amounts and cause the Company to make such tax payments as so required. All Tax Advances made on behalf of a Member shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Member. For all purposes of this Agreement such Member shall be treated as having received the amount of the distribution that is equal to the Tax Advance. Each Member hereby agrees to indemnify and hold harmless the Company and the other Members from and against any liability (including any liability for taxes, penalties, additions to tax or interest, but excluding any penalties, additions to tax or interest imposed as a result of the Company’s failure to withhold or make a tax payment on behalf of such Member which withholding or payment is required pursuant to applicable Law) with respect to income or Tax Advances attributable to such Member; provided, that any remaining Tax Advance with respect to any Member shall be required to be repaid by such Member in full prior to or in connection with (and as a condition of) any Transfer or any Class A Exchange. The obligation of a Member set forth in this Section 5.07 shall survive the withdrawal of a Member from the Company or any Transfer of a Member’s interest.

Section 5.08. Tax Matters. The Managing Member shall act as or designate a Person to act as the “partnership representative” pursuant to the Partnership Audit Provisions (the “Partnership Representative”) and such Person shall have the power to exercise any and all rights that it is or may be entitled to exercise in that capacity. The Partnership Representative shall keep the Continuing Members timely and reasonably informed as to all material tax audits, actions, examinations or proceedings relating to the Company or any of its Subsidiaries (“Tax Proceedings”). The Partnership Representative shall have the exclusive right to represent the Company in respect of any Tax Proceedings. The Members shall cooperate as reasonably requested by the Partnership Representative in connection with any election or decision made by the Partnership Representative acting in that capacity (including by filing amended tax returns and providing information requested).

Section 5.09. Other Allocation Provisions. Certain of the foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations.

C-230

In addition to amendments effected in accordance with Section 11.12 or otherwise in accordance with this Agreement, Sections 5.03, 5.04 and 5.05 may also, so long as any such amendment does not materially change the relative economic interests of the Members and the prior written consent of the Continuing Member Representative has been obtained, be amended at any time by the Managing Member if necessary, in the opinion of tax counsel to the Company, to comply with such regulations or any applicable Law.

COMPANY UNITS

Section 7.01. Units.

(a) Units. Subject to the provisions of this Agreement and subject to the approval of the Board of Directors, the Company shall be authorized to issue from time to time such number of Units and other Equity Securities as the Managing Member shall determine in accordance with and subject to the restrictions in this Section 7.01 and Section 7.02. Subject to this Section 7.01 and Section 7.02, each authorized Unit may be issued pursuant to such agreements as the Managing Member shall approve, including pursuant to warrants, options, or other rights or property to acquire Units or that may be converted into Units. Subject to the approval of the Board of Directors, the Company may reissue any Units that have been repurchased or acquired by the Company; provided that any such issuance, and the admission of any Person as a Member in connection therewith, is otherwise made in accordance with and subject to the restrictions in this LLC Agreement.

Notwithstanding the foregoing, other than in connection with any subdivision or combination in accordance with Section 7.01(j) or (k) or any Reclassification Event, from and after the Effective Date the Managing Member shall not be authorized to issue any Earnout Units. The Units shall be uncertificated. The Company shall not, and the Managing Member shall not cause the Company to, issue any Units if such issuance would result in the Company having more than 100 partners, within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)).

(b) Outstanding Units. Immediately after the Fathom Effective Time, the Units comprise Class A Units (including the Earnout Units, comprising Tier 1 Earnout Units, Tier 2 Earnout Units and Tier 3 Earnout Units). Except as otherwise provided in this Agreement, each outstanding Class A Unit (other than the Earnout Units) shall be identical to each other Class A Unit (other than the Earnout Units), each outstanding Tier 1 Earnout Unit shall be identical to each other Tier 1 Earnout Unit, each outstanding Tier 2 Earnout Unit shall be identical to each other Tier 2 Earnout Unit, and each outstanding Tier 3 Earnout Unit shall be identical to each other Tier 3 Earnout Unit. The Managing Member’s interest in its capacity as such shall be a non-economic interest in the Company, which does not entitle the Managing Member, solely in its capacity as such, to any Units, distributions or Tax Distributions.

(c) Schedule of Members. The Company shall maintain a schedule, appended hereto as Exhibit A (as updated and amended from time to time in accordance with the terms of this Agreement and current as of the date set forth therein), which shall include: (i) the name and address of each Member; (ii) the aggregate number of and type of Units issued and outstanding and held by each Member; and (iii) each Member’s Capital Contributions following the Fathom Effective Time. The number of Units of each Class held by each Member at the completion of the Equity Transactions is as set forth in the Schedule of Members (as of the Effective Date).

C-232

(d) Earnout Units. Each Earnout Unit will be held in accordance with this Agreement unless and until an Earnout Vesting Event occurs with respect to such Earnout Unit or such Earnout Unit is forfeited in accordance with Section 7.01(d)(ii).

(i) From and after the Effective Date until the occurrence of the applicable Earnout Vesting Event, each Tier 1 Earnout Unit, Tier 2 Earnout Unit and Tier 3 Earnout Unit shall be an Unvested Earnout Unit. Upon the occurrence of (i) a Tier 1 Earnout Vesting Event, with respect to the Tier 1 Earnout Units, (ii) a Tier 2 Earnout Vesting Event, with respect to the Tier 2 Earnout Units or (iii) a Tier 3 Earnout Vesting Event, with respect to the Tier 3 Earnout Units, such Earnout Units shall immediately and automatically without any further action on the part of the holder thereof or any other Person (including the Company and the Managing Member) vest and thereafter shall have all rights and privileges of a Class A Unit under this Agreement from and after the Earnout Vesting Date (together with the right to receive any applicable distributions under Section 4.01(b)). On the Effective Date, with respect to any Earnout Unit issued to a Continuing Member, Pubco shall issue to such Continuing Member one share of Class B Common Stock at par value for cash.

(ii) To the extent that, on or before the fifth (5th) anniversary of the Effective Date, an applicable Earnout Vesting Event has not occurred with respect to an Earnout Unit (and as a result such Earnout Unit is an Unvested Earnout Unit), then immediately and without any further action under this Agreement, on the date that is the fifth (5th) anniversary of the Effective Date, any such Earnout Units shall automatically be forfeited and surrendered to the Company and be canceled and extinguished for no consideration and each corresponding share of Class B Common Stock shall automatically be forfeited and surrendered to Pubco and be canceled and extinguished for no consideration.

(iii) [Reserved.]

(iv) The parties hereto intend that, for U.S. federal income tax purposes, (a) the Earnout Units received by the Continuing Members in connection with the transaction contemplated in the Business Combination Agreement not be treated as being received in connection with the performance of services and (b) no such Member be treated as having taxable income or gain as a result of such receipt of such Earnout Units or as a result of holding any such Earnout Units at the time of any Earnout Vesting Event (for avoidance of doubt, excluding any allocations as a result of the last sentence of Section 5.03) and the Company shall prepare and file all tax returns consistent therewith unless otherwise required by a “determination” within the meaning of Section 1313 of the Code. Notwithstanding (and without limiting) the foregoing, each of the Members shall, within thirty (30) days of the Effective Date, file with the IRS (via certified mail, return receipt requested) on a protective basis a completed election under Section 83(b) of the Code and the Treasury Regulations thereunder with respect to any Earnout Units so received and, upon such filing, shall thereafter notify the Company that such Member has made such timely filing and provide the Company with a copy of such election.

Restricted stock granted under any such employee benefit plan shall be treated as outstanding for purposes of Section 7.01(g)(i).

(iii) In the event any outstanding Equity Security of Pubco is exercised or otherwise converted and, as a result, any shares of Class A Common Stock or other Equity Securities of Pubco are issued, (x) the corresponding Equity Security outstanding at the Company, if any, shall be similarly exercised or otherwise converted, if applicable, (y) an equivalent number of Class A Units or equivalent Equity Securities of the Company shall be issued to Pubco, and (z) Pubco shall concurrently contribute to the Company, the net proceeds received by Pubco from any such exercise or conversion (provided, that, the Company shall not be required to reimburse hereunder any costs or expenses which were netted off the gross proceeds received).

(h) Pubco Debt Issuance. If at any time Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) issues Debt Securities, Pubco or such Subsidiary shall transfer to the Company, the net proceeds received by Pubco or such Subsidiary, as applicable, in exchange for such Debt Securities in a manner that directly or indirectly burdens the Company with the repayment of the Debt Securities (provided, that, the Company shall not be required to reimburse hereunder any costs or expenses which were netted off the gross proceeds received).

(i) New Company Issuances. Except pursuant to Section 8.04, (x) the Company may not issue any additional Units to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers an equal number of newly-issued shares of Class A Common Stock (or relevant Equity Security of such Subsidiary) to another Person or Persons, and (ii) such issuance is in accordance with Section 7.01(g), and (y) the Company may not issue any other Equity Securities of the Company to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers, to another Person, an equal number of newly-issued shares of Equity Securities of Pubco or such Subsidiary with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of the Company, and (ii) such issuance is in accordance with Section 7.01(g).

(j) Repurchases and Redemptions.

C-234

redeem, repurchase or otherwise acquire from Pubco or such Subsidiary an equal number of Class A Units for the same price per security, if any, or (B) any other Equity Securities of Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) pursuant to a Board of Directors approved repurchase plan or program (or otherwise in connection with a transaction approved by the Board of Directors), provided that substantially simultaneously therewith, the Company shall redeem, repurchase or otherwise acquire from Pubco or such Subsidiary an equal number of the corresponding class or series of Equity Securities of the Company with the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of Pubco or such Subsidiary for the same price per security, if any, and substantially equivalent form of consideration.

(ii) The Company may not redeem, repurchase or otherwise acquire (x) any Class A Units from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) an equal number of shares of Class A Common Stock for the same price per security from holders thereof or (y) any other Equity Securities of the Company from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) for the same price, and substantially equivalent form of consideration, per security an equal number of Equity Securities of Pubco (or such Subsidiary) of a corresponding class or series with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of Pubco or such Subsidiary.

(k) Equity Subdivisions and Combinations.

(i) The Company shall not in any manner effect any subdivision (by any equity split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of the outstanding Units unless approved by the Board of Directors and accompanied by an identical subdivision or combination, as applicable, of the outstanding Pubco Common Stock or other related class or series of Equity Security of Pubco, with corresponding changes made with respect to any other exchangeable or convertible Equity Securities of the Company and Pubco.

(ii) Except in accordance with Section 8.04(c), Pubco shall not in any manner effect any subdivision (by any equity split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of the outstanding Pubco Common Stock or any other class or series of Equity Security of Pubco, unless approved by the Board of Directors and accompanied by an identical subdivision or combination, as applicable, of the outstanding Units or other related class or series of Equity Security of the Company, with corresponding changes made with respect to any applicable exchangeable or convertible Equity Securities of the Company and Pubco.

If, notwithstanding the provisions of this Section 8.03(a), all or any portion of a Member’s Units are Transferred by such Member in violation of this Section 8.03(a), involuntarily, by operation of Law or otherwise, the Transferee of such Units (or portion thereof) shall not be admitted to the Company as a Member nor be entitled to any rights as a Member under this Agreement, and the Transferor will continue to be bound by all obligations under this Agreement. Any attempted or purported Transfer of all or a portion of a Member’s Units in violation of this Section 8.03(a) shall, to the fullest extent permitted by Law, be null and void ab initio and of no force or effect whatsoever. Subject to the restrictions set forth herein, (i) no shares of Class B Common Stock may be Transferred by a Member unless an equal number of Class A Units are Transferred therewith in accordance with this Agreement (including in respect of those Transfers permitted by Section 8.03(b)), and (ii) no Class A Units may be Transferred by a Member holding Class B Common Stock unless an equal number of shares of Class B Common Stock are Transferred therewith in accordance with this Agreement (including in respect of those Transfers permitted by Section 8.03(b)).

(b) The Transfer restrictions contained in Section 8.03(a) shall not apply to any Transfer (each, a “Permitted Transfer”): (i) in connection with a Class A Exchange effected in accordance with the provisions of this Agreement, (ii) by a Member to Pubco or any of its wholly-owned Subsidiaries, or (iii) by a Member to any of such Member’s Permitted Transferees, in each case, in accordance with this Section 8.03, provided, however, that, following any Permitted Transfer pursuant to clause (iii), the restrictions contained in this Agreement will continue to apply to such Units and, as a condition to such Transfer, the Transferee shall be required to execute a joinder to this Agreement and agree in writing to be bound by the provisions of this Agreement.

(i) A Class A Exchanging Member shall exercise its right to make a Class A Exchange as set forth in Section 8.04(a) above by providing such Class A Exchange Notice during normal business hours at the principal executive office of Pubco and the Company (or otherwise in accordance with Section 11.02). Within three (3) Business Days following its receipt of a Class A Exchange Notice, the Managing Member may elect to settle all or a portion of the Class A Exchanged Units in cash in an amount equal to the Class A Cash Amount (in lieu of shares of Class A Common Stock), by giving written notice of such election to the Class A Exchanging Member within such three (3) Business Day period (such notice, the “Cash Exchange Notice”). The Cash Exchange Notice shall set forth the portion of the Class A Exchanged Units subject to the Class A Exchange which shall be exchanged for cash in lieu of Class A Common Stock. To the extent any Class A Exchange relates to the exercise of the Class A Exchanging Member’s registration rights under the Registration Rights Agreement, Pubco and the Company shall cooperate in good faith with such Class A Exchanging Member to exercise such Class A Exchange in a manner which preserves such Class A Exchanging Member’s rights thereunder. At any time following the delivery of a Cash Exchange Notice and prior to the Class A Exchange Date, the Managing Member may elect (by giving written notice of such election to the Class A Exchanging Member) to revoke the Cash Exchange Notice with respect to all or any portion of the Class A Exchanged Units and instead deliver the applicable Class A Exchanged Shares with respect to any such Class A Exchanged Units on the Class A Exchange Date.

(ii) [Reserved].

(iii) Each Class A Exchange shall be consummated on the Class A Exchange Date. On the Class A Exchange Date (to be effective immediately prior to the close of business on the Class A Exchange Date), (a) Pubco shall contribute to the Company for delivery to the Class A Exchanging Member (x) the Class A Exchanged Shares with respect to such Class A Exchanged Units not subject to a Cash Exchange Notice and (y) the Class A Cash Amount with respect to any Class A Exchanged Units subject to a Cash Exchange Notice, (b) the Class A Exchanging Member shall transfer and surrender the Class A Exchanged Units to the Company, free and clear of all liens and encumbrances, (c) the Company shall issue to Pubco a number of Class A Units equal to the number of shares of Class A Common Stock to be delivered pursuant to clause (a)(x), (d) solely to the extent necessary in connection with a Class A Exchange, Pubco shall undertake all actions, including an issuance, reclassification, distribution, division or recapitalization, with respect to the Class A Common Stock necessary in order to maintain a one-to-one ratio between the number of Class A Units owned by Pubco, directly or indirectly, and the number of outstanding shares of Class A Common Stock, taking into account the issuance in clause (c), any Class A Exchanged Shares, and any other action taken in connection with this Section 8.04, (e) the Company shall (x) cancel the redeemed Class A Units which were Class A Exchanged Units held by the Class A Exchanging Member and (y) transfer to the Class A Exchanging Member the Class A Cash Amount and/or the Class A Exchanged Shares, as applicable, and (f) Pubco shall cancel the surrendered shares of Class B Common Stock. Upon the Class A Exchange of all of a Member’s Class A Units, such Class A Member shall cease to be a Class A Member of the Company.

(iv) The Company and each Class A Exchanging Member shall bear their own expenses in connection with the consummation of any Class A Exchange, except that the Company shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Class A Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered in a name other than that of the Class A Exchanging Member, then such Class A Exchanging Member and/or the person in whose name such shares are to be delivered shall pay to the Company the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange or shall establish to the reasonable satisfaction of the Company that such tax has been paid or is not payable (and shall indemnify the Company in the event such transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange are not so paid).

C-238

(v) Pubco may adopt reasonable procedures for the implementation of the Class A Exchange provisions set forth in this Section 8.04; provided that without the consent of each Continuing Member, Pubco shall not adopt any procedures inconsistent with or that impair or adversely affect the rights of a Member to Exchange Class A Units pursuant to this Agreement. A Class A Exchanging Member may not revoke a Class A Exchange Notice delivered pursuant to Section 8.04(a) above without the consent of the Managing Member, which consent may not be unreasonably withheld, delayed or conditioned.

(vi) Notwithstanding anything to the contrary herein, additional restrictions may be imposed on Class A Exchanges by the Managing Member as provided in Section 8.06(b).

(c) Adjustment. If there is: (i) any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Class A Units that is not accompanied by an identical subdivision or combination of the Class A Common Stock; or (ii) any subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Common Stock that is not accompanied by an identical subdivision or combination of the Units, then, in each case, to the extent necessary to maintain the economic equivalency in the value surrendered for exchange and the value received, the Managing Member shall in good faith adjust the number of shares of Class A Common Stock for which a Class A Unit is entitled to be exchanged under this Section 8.04 accordingly. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed into another security, securities or other property, then upon any subsequent Class A Exchange, a Class A Exchanging Member shall be entitled to receive the amount of such security, securities or other property that such Class A Exchanging Member would have received if such Class A Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. Except as may be required in the immediately preceding sentence, no adjustments in respect of distributions shall be made upon a Class A Exchange.

(d) Class A Common Stock to be Issued.

(i) Pubco shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon a Class A Exchange, such number of shares of Class A Common Stock as shall be deliverable upon any such Class A Exchange; provided that nothing contained herein shall be construed to preclude the Company from satisfying its obligations in respect of the Class A Exchange by delivery of shares of Class A Common Stock which are held in the treasury of Pubco or any of its subsidiaries (other than the Company or any of its subsidiaries) or by delivery of purchased shares of Class A Common Stock (which may or may not be held in the treasury of Pubco or any subsidiary thereof). Pubco and the Company covenant that all Class A Common Stock issued upon a Class A Exchange will, upon issuance, be validly issued, fully paid and non-assessable.

(ii) Pubco and the Company covenant and agree that, to the extent that a Registration Statement under the Securities Act is effective and available for shares of Class A Common Stock to be delivered with respect to any Class A Exchange, shares that have been registered under the Securities Act shall be delivered in respect of such Class A Exchange. In the event that any Class A Exchange in accordance with this Agreement is to be effected at a time when any required registration has not become effective or otherwise is unavailable, upon the request and with the reasonable cooperation of the applicable Class A Exchanging Member, Pubco and the Company shall use commercially reasonable efforts to promptly facilitate such Exchange pursuant to any reasonably available exemption from such registration requirements. Pubco and the Company shall use

C-239

commercially reasonable efforts to list the Class A Common Stock required to be delivered upon a Class A Exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Class A Common Stock may be listed or traded at the time of such delivery.

(e) Pubco Offers. In the event that a tender offer, share exchange offer, or take-over bid or similar transaction with respect to Class A Common Stock or another Equity Security of Pubco (a “Pubco Offer”) is proposed by Pubco or is proposed to Pubco or its stockholders, the holders of Class A Units (or such other Equity Security of the Company corresponding to such Pubco Equity Security) shall be permitted to participate in such Pubco Offer by delivery of a Class A Exchange Notice (which Class A Exchange Notice shall be effective immediately prior to the consummation of such Pubco Offer (and, for the avoidance of doubt, shall be contingent upon such Pubco Offer and not be effective if such Pubco Offer is not consummated)). In the case of a Pubco Offer, Pubco shall use its reasonable best efforts to take all such actions and do all such things as are necessary or desirable to enable and permit the holders of Class A Units or other Equity Security to participate in such Pubco Offer to the same extent or on an economically equivalent basis as the holders of shares of Class A Common Stock or other Equity Security without discrimination; provided that, without limiting the generality of this sentence (and without limiting the ability of any Member holding Class A Units or such other Equity Security to consummate a Class A Exchange at any time pursuant to the terms of this Agreement), the Managing Member shall use its reasonable best efforts to ensure that such holders of Class A Units or such other Equity Security may participate in such Pubco Offer without being required to effect a Class A Exchange of their Class A Units and cancel their shares of Class B Common Stock, as the case may be, (or, if so required, to ensure that any such Class A Exchange and cancelation shall be effective only upon, and shall be conditional upon, the closing of the transactions contemplated by the Pubco Offer). For the avoidance of doubt, in no event shall the holders of Class A Units be entitled to receive in such Pubco Offer aggregate consideration for each Class A Unit and share of Class B Common Stock, taken together, that is greater than or less than the consideration payable in respect of each share of Class A Common Stock in connection with such Pubco Offer (it being understood that payments under or in respect of the Tax Receivable Agreement shall not be considered part of any such consideration, and shall be in addition thereto).

(f) Pubco Call Rights. Notwithstanding anything to the contrary contained in this Section 8.04, with respect to any Class A Exchange Notice, a Class A Exchanging Member shall be deemed to have offered to sell its Class A Exchanged Units as described in any Class A Exchange Notice directly to Pubco (rather than to the Company), and Pubco may, by delivery of a written notice to the Class A Exchanging Member no later than three (3) Business Days following the giving of a Class A Exchange Notice, in accordance with, and subject to the terms of, this Section 8.4(f) (such notice, a “Pubco Call Notice”), elect to purchase directly and acquire such Class A Exchanged Units on the Class A Exchange Date by paying to the Class A Exchanging Member (or such other Person specified in the Class A Exchange Notice) the Class A Exchanged Shares and/or Class A Cash Amount with respect to the Class A Exchanged Units, whereupon Pubco shall acquire the Class A Exchanged Units on the Class A Exchange Date and be treated for all purposes of this Agreement as the owner of such Class A Units. Except as otherwise provided in this Section 8.04(f), an exercise of the call right of Pubco set forth in this Section 8.04(f) shall be consummated pursuant to the same timeframe and in the same manner as the relevant Class A Exchange would have been consummated if Pubco had not given a Pubco Call Notice, in each case as relevant.

(g) Distribution Rights. No Class A Exchange shall impair the right of the Class A Exchanging Member to receive any distributions payable on the Units redeemed pursuant to such Class A Exchange in respect of a record date that occurs prior to the Class A Exchange Date for such Class A Exchange. No Class A Exchanging Member, or a Person designated by a Class A Exchanging Member to receive shares of Class A Common Stock, shall be entitled to receive, with respect to such record date, distributions or dividends both on Class A Units redeemed by the Company from such Class A Exchanging Member and on shares of Class A Common Stock received by such Class A Exchanging Member, or other Person so designated, if applicable, in such Class A Exchange.

C-240

(h) Tax Treatment. For U.S. federal and applicable state and local income tax purposes, each of the Class A Exchanging Member, the Company and Pubco agree to treat each Class A Exchange as a sale by the Class A Exchanging Member of the Class A Exchanging Member’s Class A Units (together with a corresponding number of outstanding shares of Class B Common Stock, which shares shall not be allocated economic value in excess of par value) to Pubco in exchange for the Class A Common Stock.

Section 8.05. [Reserved].

Section 8.06. Further Restrictions.

(a) Notwithstanding any contrary provision in this Agreement, other than with respect to Transfers in accordance with Section 8.04, in no event may any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that:

(i) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit;

(ii) such Transfer would require the registration of such transferred Unit or of any Class of Unit pursuant to any applicable U.S. federal or state securities laws (including, without limitation, the Securities Act or the Exchange Act) or other non-U.S. securities laws (including Canadian provincial or territorial securities laws) or would constitute a non-exempt distribution pursuant to applicable provincial or state securities laws; or

(iii) such Transfer would cause (i) all or any portion of the assets of the Company to (A) constitute “plan assets” (under ERISA, the Code or any applicable Similar Law) of any existing or contemplated Member, or (B) be subject to the provisions of ERISA, Section 4975 of the Code or any applicable Similar Law, or (ii) the Managing Member to become a fiduciary with respect to any existing or contemplated Member, pursuant to ERISA, any applicable Similar Law, or otherwise.

(b) Notwithstanding any contrary provision in this Agreement, in no event shall any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that such Transfer would pose a material risk that such Transfer would (i) be considered to be effected on or through an “established securities market” or a “secondary market or the substantial equivalent thereof” as such terms are used in Treasury Regulations Section 1.7704-1, (ii) result in the Company having more than 100 partners, within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)), or (iii) cause the Company to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the Treasury Regulations promulgated thereunder. In addition, notwithstanding any contrary provision in this Agreement, to the extent the Managing Member reasonably determines that additional restrictions on Transfers (including, for the avoidance of doubt, Class A Exchanges) are advisable to minimize the risk that the Company is not treated as a “publicly traded partnership” under Section 7704 of the Code, the Managing Member shall impose such additional restrictions on Transfers as the Managing Member reasonably determines to be so advisable.

(c) To the fullest extent permitted by law, any Transfer in violation of this Article VIII shall be deemed null and void ab initio and of no effect.

Section 8.07. Rights of Assignees. The Transferee of any Permitted Transfer permitted pursuant to this Article VIII will be an assignee only (“Assignee”), and only will receive, to the extent transferred, the distributions and allocations of income, gain, loss, deduction, credit or similar item to which the Member which transferred its Units would be entitled, and such Assignee will not be entitled or enabled to exercise any other rights or powers of a Member, such other rights, and all obligations relating to, or in connection with, such interest remaining with the transferring Member, unless and until such time as such Transferee is admitted to the Company as a Member pursuant to Section 8.09. The transferring Member will remain a Member even if it has transferred all of its Units to one or more Assignees until such time as all such Assignee(s) have been admitted to the Company as a Member pursuant to Section 8.09.

C-241

Section 8.08. Admissions, Resignations and Removals.

(a) Pubco shall not, by any means, resign as, cease to be or be replaced as Managing Member except in compliance with this Section 8.08 and except with the approval of a majority of the independent directors serving on the Board of Directors. No termination or replacement of Pubco as Managing Member shall be effective unless proper provision is made, in compliance with this Agreement, so that the obligations of Pubco, its successor by merger (if applicable) and any new Managing Member and the rights of all Members under this Agreement and applicable Law remain in full force and effect. No appointment of a Person other than Pubco (or its successor by merger, as applicable) as Managing Member shall be effective unless (a) the new Managing Member executes a joinder to this Agreement and agrees to be bound by the terms and conditions in this Agreement, and (b) Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable) provide all other Members with contractual rights, directly enforceable by such other Members against Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable), to cause (i) Pubco to comply with all Pubco’s obligations under this Agreement (including its obligations under Section 8.04 and 7.01(c)(iii)) other than those that must necessarily be taken solely in its capacity as Managing Member and (ii) the new Managing Member to comply with all the Managing Member’s obligations under this Agreement.

(b) No Member will be removed or entitled to resign from being a Member of the Company except in accordance with Section 8.10 hereof. Any additional Managing Member or substitute Managing Member admitted as a Managing Member of the Company pursuant to this Section 8.08 is hereby authorized to, and shall, continue the Company without dissolution.

(c) Except as otherwise provided in Article IX or the Act, no admission, substitution, resignation or removal of a Member will cause the dissolution of the Company. To the fullest extent permitted by law, any purported admission, resignation or removal that is not in accordance with this Agreement shall be null and void.

Section 8.09. Admission of Assignees as Substitute Members. An Assignee will become a substitute Member only if and when each of the following conditions is satisfied:

(a) the Managing Member consents in writing to such admission (to the extent required in accordance with Section 8.03);

(b) if required by the Managing Member, the Managing Member receives written instruments (including, without limitation, copies of any instruments of Transfer) that are in a form satisfactory to the Managing Member; and

(c) such Assignee signs a joinder or counterpart to this Agreement agreeing to become a party to and bound by this Agreement as a substitute Member.

Section 8.10. Resignation and Removal of Members. Subject to Section 8.07, if a Member (other than the Managing Member) ceases to hold any Units, then such Member shall cease to be a Member and to have the power to exercise any rights or powers of a member of the Company, and shall be deemed to have resigned from the Company.

ARTICLE IX

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 9.01. No Dissolution. Except as required by the Act, the Company shall not be dissolved by the admission of additional Members or resignation of Members in accordance with the terms of this Agreement. The Company may be dissolved, liquidated, wound up and terminated only pursuant to the provisions of this Article IX, and the Members hereby irrevocably waive any and all other rights they may have to cause a dissolution of the Company or a sale or partition of any or all of the Company assets.

C-242

Section 9.02. Events Causing Dissolution. The Company shall be dissolved and its affairs shall be wound up upon the occurrence of any of the following events (each, a “Dissolution Event”):

(a) the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act upon the finding by a court of competent jurisdiction that it is not reasonably practicable to carry on the business of the Company in conformity with this Agreement;

(b) any event which makes it unlawful for the business of the Company to be carried on by the Members;

(c) the written consent of all Members;

(d) at any time there are no Members, unless the Company is continued in accordance with the Act; or

(e) the determination of the Managing Member, with the consent of the Continuing Member Representative for so long as the Continuing Members hold Units; provided that in the event of a dissolution pursuant to this clause (e), the relative economic rights of each Class of Units immediately prior to such dissolution shall be preserved to the greatest extent practicable with respect to distributions made to Members pursuant to Section 9.03 below in connection with the winding up of the Company, taking into consideration tax and other legal constraints that may adversely affect one or more parties hereto and subject to compliance with applicable laws and regulations, unless, and to the extent that, with respect to any Class of Units, holders of not less than 75% of the Units of such Class consent in writing to a treatment other than as described above; provided, that prior to the occurrence of a Tier 1 Earnout Vesting Event, a Tier 2 Earnout Vesting Event or a Tier 3 Earnout Vesting Event with respect to the Tier 1 Earnout Units, the Tier 2 Earnout Units and the Tier 3 Earnout Units, respectively, such Units shall not have any economic rights under this Agreement.

Section 9.03. Distribution upon Dissolution. Upon dissolution, the Company shall not be terminated and shall continue until the winding up of the affairs of the Company is completed. Upon the winding up of the Company, the Managing Member, or any other Person designated by the Managing Member (the “Liquidation Agent”), shall take full account of the assets and liabilities of the Company and shall, unless the Managing Member determines otherwise, liquidate the assets of the Company as promptly as is consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be applied and distributed in the following order:

(a) First, to the satisfaction of debts and liabilities of the Company (including satisfaction of all indebtedness to Members and/or their Affiliates to the extent otherwise permitted by law) including the expenses of liquidation, and including the establishment of any reserve which the Liquidation Agent shall deem reasonably necessary for any contingent, conditional or unmatured contractual liabilities or obligations of the Company (“Contingencies”). Any such reserve may be paid over by the Liquidation Agent to any attorney-at-law, or acceptable party, as escrow agent, to be held for disbursement in payment of any Contingencies and, at the expiration of such period as shall be deemed advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter provided in this Section 9.03;

(b) Second, to the satisfaction of (i) any payments due pursuant to Section 4.01(b), if any, to the Members holding Class A Units for which such distributions are due, pro rata in accordance with all such Members’ respective Class A Units for which such distributions are due; and

(c) The balance, if any, to the Members, pro rata in accordance with the Members’ respective Class A Units other than Unvested Earnout Units.

Section 9.04. Time for Liquidation. A reasonable amount of time shall be allowed for the orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation.

C-243

Section 9.05. Termination. The Company shall terminate when all of the assets of the Company, after payment of or due provision for all debts, liabilities and obligations of the Company, shall have been distributed to the holders of Units in the manner provided for in this Article IX, and the Certificate shall have been cancelled in the manner required by the Act.

Section 9.06. Claims of the Members. The Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members shall have no recourse against the Company or any other Member or any other Person. No Member with a negative balance in such Member’s Capital Account shall have any obligation to the Company or to the other Members or to any creditor or other Person to restore such negative balance during the existence of the Company, upon dissolution or termination of the Company or otherwise, except to the extent required by the Act.

Section 9.07. Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the provisions of Section 5.07, Section 5.08, Section 10.02, Section 11.09 and Section 11.10 shall survive the termination of the Company.

ARTICLE X

LIABILITY AND INDEMNIFICATION

Section 10.01. Liability of Members.

(a) No Member and no Affiliate, manager, member, employee or agent of a Member shall be liable for any debt, obligation or liability of the Company or of any other Member or have any obligation to restore any deficit balance in its Capital Account solely by reason of being a Member of the Company, except to the extent required by the Act.

(b) This Agreement is not intended to, and does not, create or impose any duty (including any fiduciary duty) on any of the Members (other than the Managing Member in its capacity as such) hereto or on their respective Affiliates. Further, notwithstanding any other provision of this Agreement or any duty otherwise existing at law or in equity, the parties hereto agree that no Member (other than the Managing Member, in its capacity as such, as set forth in Section 3.06) shall, to the fullest extent permitted by law, have any duties (including fiduciary duties) to any other Member or to the Company, and in doing so, the parties recognize, acknowledge and agree that their duties and obligations to one another and to the Company are only as expressly set forth in this Agreement; provided, however, that each Member shall have the duty to act in accordance with the implied contractual covenant of good faith and fair dealing.

(c) To the extent that, at law or in equity, any Member has duties (including fiduciary duties) and liabilities relating thereto to the Company, to another Member or to another Person who is a party to or is otherwise bound by this Agreement, the Members (other than the Managing Member in its capacity as such) acting under this Agreement will not be liable to the Company, to any such other Member or to any such other Person who is a party to or is otherwise bound by this Agreement, for their good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Member otherwise existing at law or in equity, are agreed by the Members to replace to that extent such other duties and liabilities of the Members relating thereto.

(d) The Managing Member may consult with legal counsel, accountants and financial or other advisors selected by it, and any act or omission taken by the Managing Member on behalf of the Company or in furtherance of the interests of the Company in good faith in reliance upon and in accordance with the advice of such Person as to matters the Managing Member reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance with such opinion or advice, and the Managing Member will be fully protected in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care.

C-244

Section 10.02. Indemnification.

(a) Exculpation and Indemnification. Notwithstanding any other provision of this Agreement, whether express or implied, to the fullest extent permitted by law, no Indemnitee shall be liable to the Company or any Member for any act or omission in relation to the Company or this Agreement or any transaction contemplated hereby taken or omitted by an Indemnitee in good faith and in the reasonable belief that such act or omission was in the best interests of the Company. To the fullest extent permitted by law, as the same exists or hereafter be amended (but in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the Company to provide prior to such amendment), the Company shall indemnify any Indemnitee who was or is made or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Company or otherwise), whether civil, criminal, administrative, arbitrative or investigative, and whether formal or informal (hereinafter a “Proceeding”), including appeals, by reason of his or her or its status as an Indemnitee or by reason of any action alleged to have been taken or omitted to be taken by an Indemnitee in such capacity, from and against all loss and liability suffered and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by such Indemnitee in connection with such action, suit or proceeding, including appeals; provided that such Indemnitee shall not be entitled to indemnification hereunder if, but only to the extent that, such Indemnitee’s conduct constituted fraud, bad faith, gross negligence or willful misconduct. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to indemnify an Indemnitee in connection with any action, suit or proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member, and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent. The indemnification of an Indemnitee of the type identified in clause (e) of the definition of Indemnitee shall be secondary to any and all indemnification to which such Indemnitee is entitled from the relevant other Person (including any payment made to such Indemnitee under any insurance policy issued to or for the benefit of such Person or Indemnitee) (the “Primary Indemnification”), and will only be paid to the extent the Primary Indemnification is not paid and/or does not provide coverage (e.g., a self-insured retention amount under an insurance policy). No such Person shall be entitled to contribution or indemnification from or subrogation against the Company. The indemnification of any other Indemnitee shall, to the extent not in conflict with such policy, be secondary to any and all payment to which such Indemnitee is entitled from any relevant insurance policy issued to or for the benefit of the Company or any Indemnitee. For the avoidance of doubt, this Agreement shall not affect the indemnification and advancement of rights provided pursuant to the Existing Agreement in favor of any Person relating to proceedings arising out of actions or omissions occurring in whole or in part prior to the effectiveness of this Agreement.

(b) Advancement of Expenses. To the fullest extent permitted by law, the Company shall promptly pay reasonable expenses (including attorneys’ fees) incurred by any Indemnitee in appearing at, participating in or defending any Proceeding in advance of the final disposition of such Proceeding, including appeals, upon presentation of an undertaking on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Section 10.02 or otherwise. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to pay expenses of an Indemnitee in connection with any Proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent.

(c) Unpaid Claims. If a claim for indemnification (following the final disposition of such Proceeding) or advancement of expenses under this Section 10.02 is not paid in full within thirty (30) days after a written claim therefor by any Indemnitee has been received by the Company, such Indemnitee may file proceedings to recover the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of

C-245

prosecuting such claim. In any such action the Company shall have the burden of proving that such Indemnitee is not entitled to the requested indemnification or advancement of expenses under applicable Law.

(d) Insurance. To the fullest extent permitted by law, the Company may purchase and maintain insurance on behalf of any person described in Section 10.02(a) against any liability asserted against such person, whether or not the Company would have the power to indemnify such person against such liability under the provisions of this Section 10.02 or otherwise.

(i) In the event of any payment by the Company under this Section 10.02, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee from any relevant other Person or under any insurance policy issued to or for the benefit of the Company, such relevant other Person, or any Indemnitee. Each Indemnitee agrees to execute all papers required and take all action necessary to secure such rights, including the execution of such documents as are necessary to enable the Company to bring suit to enforce any such rights in accordance with the terms of such insurance policy or other relevant document. The Company shall pay or reimburse all expenses actually and reasonably incurred by the Indemnitee in connection with such subrogation.

(ii) The Company shall not be liable under this Section 10.02 to make any payment of amounts otherwise indemnifiable hereunder (including, but not limited to, judgments, fines and amounts paid in settlement, and excise taxes with respect to an employee benefit plan or penalties) if and to the extent that the applicable Indemnitee has otherwise actually received such payment under this Section 10.02 or any insurance policy, contract, agreement or otherwise.

(i) to select those Eligible Recipients who shall be Participants;

(ii) to determine whether and to what extent Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units, Other Share-Based Awards, Other Cash-Based Awards or a combination of any of the foregoing, are to be granted hereunder to Participants;

(iii) to determine the number of Shares to be made subject to each Award;

(vi) to determine Fair Market Value;

(vii) to determine the duration and purpose of leaves of absence which may be granted to a Participant without constituting termination of the Participant’s employment for purposes of Awards granted under the Plan;

(viii) to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable;

(ix) to reconcile any inconsistency in, correct any defect in and/or supply any omission in the Plan, any Award Agreement or other instrument or agreement relating to the Plan or an Award granted under the Plan; and

C-260

(x) to construe and interpret the terms and provisions of the Plan and any Award issued under the Plan (and any Award Agreement relating thereto), and to otherwise supervise the administration of the Plan and to exercise all powers and authorities either specifically granted under the Plan or necessary and advisable in the administration of the Plan.

(c) All decisions made by the Administrator pursuant to the provisions of the Plan shall be final, conclusive and binding on all persons, including the Company and the Participants. No member of the Board or the Committee, or any officer or employee of the Company or any Subsidiary thereof acting on behalf of the Board or the Committee, shall be personally liable for any action, omission, determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Board or the Committee and each and any officer or employee of the Company and of any Subsidiary thereof acting on their behalf shall, to the maximum extent permitted by law, be fully indemnified and protected by the Company in respect of any such action, omission, determination or interpretation.

Section 4. Shares Reserved for Issuance Under the Plan and Limitations on Awards.

(a) Subject to adjustment in accordance with Section 5 of the Plan, the Administrator is authorized to deliver with respect to Awards granted under the Plan an aggregate of [●] shares of Common Stock.

(b) Notwithstanding anything herein to the contrary, the maximum number of Shares subject to Awards granted during any fiscal year to any Non-Employee Director, taken together with any cash fees paid to such Non-Employee Director during the fiscal year with respect to such Director’s service as a Non-Employee Director, shall not exceed $900,000 (calculating the value of any such Awards based on the grant date Fair Market Value of such Awards for financial reporting purposes); provided, that any Awards granted under the Plan or other compensation received by a Non-Employee Director related to the settlement, conversion or substitution of the Non-Employee Director’s award(s) under the Prior Plan shall not count against such limit.

(c) Shares issued under the Plan may, in whole or in part, be authorized but unissued Shares or Shares that shall have been or may be reacquired by the Company in the open market, in private transactions or otherwise. Any shares of Common Stock subject to an Award under the Plan that, after the Effective Date, are forfeited, canceled, settled or otherwise terminated without a distribution of Shares to a Participant will thereafter be deemed to be available for Awards with respect to shares of Common Stock. In applying the immediately preceding sentence, if (i) Shares otherwise issuable or issued in respect of, or as part of, any Award are withheld to cover taxes or any applicable Exercise Price, such Shares shall be treated as having been issued under the Plan and shall not be available for issuance under the Plan, and (ii) any Share-settled Stock Appreciation Rights or Options are exercised, the aggregate number of Shares subject to such Stock Appreciation Rights or Options shall be deemed issued under the Plan and shall not be available for issuance under the Plan. In addition, Shares (x) tendered to exercise outstanding Options or other Awards, (y) withheld to cover applicable taxes on any Awards or (z) repurchased on the open market using Exercise Price proceeds shall not be available for issuance under the Plan. For the avoidance of doubt, (A) Shares underlying Awards that are subject to the achievement of performance goals shall be counted against the Share reserve based on the target value of such Awards unless and until such time as such Awards become vested and settled in Shares, and (B) Awards that, pursuant to their terms, may be settled only in cash shall not count against the Share reserve set forth in Section 4(a).

(d) Substitute Awards shall not reduce the Shares authorized for grant under the Plan. In the event that a company acquired by the Company or any Affiliate or with which the Company or any Affiliate combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan; provided, that Awards using such available Shares shall

C-261

not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not employed by or providing services to the Company or its Affiliates immediately prior to such acquisition or combination.

(e) In the event that the Company or an Affiliate thereof consummates a transaction described in Code Section 424(a) (e.g., the acquisition of property or stock from an unrelated corporation), persons who become Employees or Directors in account of such transaction may be granted Substitute Awards in substitution for awards granted by their former employer, and any such substitute Options or Stock Appreciation Rights may be granted with an Exercise Price less than the Fair Market Value of a Share on the grant date thereof; provided, however, the grant of such substitute Option or Stock Appreciation Right shall not constitute a “modification” as defined in Code Section 424(h)(3) and the applicable Treasury regulations.

Section 5. Equitable Adjustments.

In the event of any Change in Capitalization, including, without limitation, a Change in Control, an equitable substitution or proportionate adjustment shall be made, in each case, as may be determined by the Administrator, in its sole discretion, in (a) the aggregate number of Shares reserved for issuance under the Plan, (b) the kind, number and Exercise Price subject to outstanding Options and Stock Appreciation Rights granted under the Plan; provided, however, that any such substitution or adjustment with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A, and (c) the kind, number and purchase price of Shares subject to outstanding Restricted Shares or Other Share-Based Awards granted under the Plan, in each case as may be determined by the Administrator, in its sole discretion; provided, however, that any fractional Shares resulting from the adjustment shall be eliminated. Such other equitable substitutions or adjustments shall be made as may be determined by the Administrator, in its sole discretion. Without limiting the generality of the foregoing, in connection with a Change in Capitalization, the Administrator may provide, in its sole discretion, for the cancellation of any outstanding Award granted hereunder (i) in exchange for payment in cash or other property having an aggregate Fair Market Value of the Shares covered by such Award, reduced by the aggregate Exercise Price or purchase price thereof, if any, and (ii) with respect to any Awards for which the Exercise Price or purchase price per share of Common Stock is greater than or equal to the then current Fair Market Value per share of Common Stock, for no consideration. Notwithstanding anything contained in the Plan to the contrary, any adjustment with respect to an Incentive Stock Option due to an adjustment or substitution described in this Section 5 shall comply with the rules of Code Section 424(a), and in no event shall any adjustment be made which would render any Incentive Stock Option granted hereunder to be disqualified as an incentive stock option for purposes of Code Section 422. The Administrator’s determinations pursuant to this Section 5 shall be final, binding and conclusive.

Section 6. Eligibility.

The Participants under the Plan shall be selected from time to time by the Administrator, in its sole discretion, from among Eligible Recipients.

Section 7. Options.

(a) General. The Administrator may, in its sole discretion, grant Options to Participants. Solely with respect to Participants who are Employees, the Administrator may grant Incentive Stock Options, Nonqualified Stock Options or a combination of both. With respect to all other Participants, the Administrator may grant only Nonqualified Stock Options. Each Participant who is granted an Option shall enter into an Award Agreement with the Company, containing such terms and conditions as the Administrator shall determine, in its sole discretion, which Award Agreement shall specify whether the Option is an Incentive Stock Option or a Nonqualified Stock Option and shall set forth, among other things, the Exercise Price of the Option, the term of the Option and provisions regarding exercisability of the Option granted thereunder. The provisions of each Option need not be the same with respect to each Participant. More than one Option may be granted to the same

C-262

Participant and be outstanding concurrently hereunder. Options granted under the Plan shall be subject to the terms and conditions set forth in this Section 7 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable and set forth in the applicable Award Agreement. The prospective recipient of an Option shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(b) Limits on Incentive Stock Options. If the Administrator grants Incentive Stock Options, then to the extent that the aggregate fair market value of Shares with respect to which Incentive Stock Options are exercisable for the first time by any individual during any calendar year (under all plans of the Company) exceeds $100,000, such Options will be treated as Nonqualified Stock Options to the extent required by Code Section 422. Subject to Section 5, the maximum number of shares that may be issued pursuant to Options intended to be Incentive Stock Options is [●] Shares and, for the avoidance of doubt, such share limit shall not be subject to the annual adjustment provided in Section 4(a).

(c) Exercise Price. The Exercise Price of Shares purchasable under an Option shall be determined by the Administrator in its sole discretion at the time of grant; provided, however, that (i) in no event shall the Exercise Price of an Option be less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant, and (ii) no Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) shall have an Exercise Price per Share less than one-hundred ten percent (110%) of the Fair Market Value of a Share on such date.

(d) Option Term. The maximum term of each Option shall be fixed by the Administrator, but in no event shall (i) an Option be exercisable more than ten (10) years after the date such Option is granted, and (ii) an Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) be exercisable more than five (5) years after the date such Option is granted. Each Option’s term is subject to earlier expiration pursuant to the applicable provisions in the Plan and the Award Agreement. Notwithstanding the foregoing, the Administrator shall have the authority to accelerate the exercisability of any outstanding Option at such time and under such circumstances as the Administrator, in its sole discretion, deems appropriate. Notwithstanding any contrary provision in this Plan (including, without limitation, Section 7(h)), if, on the date an outstanding Option would expire, the exercise of the Option, including by a “net exercise” or “cashless” exercise, would violate applicable securities laws or any insider trading policy maintained by the Company from time to time, the expiration date applicable to the Option will be extended, except to the extent such extension would violate Code Section 409A, to a date that is thirty (30) calendar days after the date the exercise of the Option would no longer violate applicable securities laws or any such insider trading policy.

(e) Exercisability. Each Option shall be exercisable at such time or times and subject to such terms and conditions, including the attainment of pre-established Performance Goals, as shall be determined by the Administrator in the applicable Award Agreement. The Administrator may also provide that any Option shall be exercisable only in installments, and the Administrator may waive such installment exercise provisions at any time, in whole or in part, based on such factors as the Administrator may determine in its sole discretion. Notwithstanding anything to the contrary contained herein, an Option may not be exercised for a fraction of a share.

(f) Method of Exercise. Options may be exercised in whole or in part by giving written notice of exercise to the Company specifying the number of Shares to be purchased, accompanied by payment in full of the aggregate Exercise Price of the Shares so purchased in cash or its equivalent, as determined by the Administrator. As determined by the Administrator, in its sole discretion, with respect to any Option or category of Options, payment in whole or in part may also be made (i) by means of consideration received under any cashless exercise procedure approved by the Administrator (including the withholding of Shares otherwise issuable upon exercise),

C-263

(ii) in the form of unrestricted Shares already owned by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such Option shall be exercised, (iii) any other form of consideration approved by the Administrator and permitted by applicable law, or (iv) any combination of the foregoing. In determining which methods a Participant may utilize to pay the Exercise Price, the Administrator may consider such factors as it determines are appropriate; provided, however, that with respect to Incentive Stock Options, all such discretionary determinations shall be made by the Administrator at the time of grant and specified in the Award Agreement.

(g) Rights as Stockholder. A Participant shall have no rights to dividends or any other rights of a stockholder with respect to the Shares subject to an Option until the Participant has given written notice of the exercise thereof, has paid in full for such Shares and has satisfied the requirements of Section 16 of the Plan.

(h) Termination of Employment or Service. Unless the applicable Award Agreement provides otherwise, in the event that the employment or service of a Participant with the Company and all Affiliates thereof shall terminate, the following terms and conditions shall apply:

(i) In the event of the termination of a Participant’s employment or service by the Company without Cause or due to a resignation by the Participant for any reason, (A) Options granted to such Participant, to the extent that they are exercisable at the time of such termination, shall remain exercisable until the date that is ninety (90) days after such termination (with such period being extended to one (1) year after the date of such termination in the event of the Participant’s death during such ninety (90) day period), on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(ii) In the event of the termination of a Participant’s employment or service as a result of the Participant’s Disability or death, (A) Options granted to such Participant, to the extent that they were exercisable at the time of such termination, shall remain exercisable until the date that is one (1) year after such termination, on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(iii) In the event of the termination of a Participant’s employment or service for Cause, all outstanding Options granted to such Participant shall expire at the commencement of business on the date of such termination.

(iv) For purposes of determining which Options are exercisable upon termination of employment or service for purposes of this Section 7(h), Options that are not exercisable solely due to a blackout period shall be considered exercisable.

(v) Notwithstanding anything herein to the contrary, an Incentive Stock Option may not be exercised more than three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability. In the event that an Option is exercisable following the date that is three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability, such Option shall be deemed to be a Nonqualified Stock Option.

(i) Other Change in Employment Status. An Option may be affected, both with regard to vesting schedule and termination, by leaves of absence, changes from full-time to part-time employment, partial disability or other changes in the employment status or service of a Participant, as evidenced in a Participant’s Award Agreement.

(j) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Options shall be subject to Section 12 of the Plan.

(k) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable

C-264

Option outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. In the sole discretion of the Administrator, payment of the exercise price of any such Option shall be made pursuant to Section 7(f)(i) or (ii), and the Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 7(k) shall not apply to an Option if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Option with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 7(k).

Section 8. Stock Appreciation Rights.

(a) General. Stock Appreciation Rights may be granted either alone (“Free Standing Rights”) or in conjunction with all or part of any Option granted under the Plan (“Related Rights”). Any Related Right that relates to a Nonqualified Stock Option may be granted at the same time the Option is granted or at any time thereafter, but before the exercise or expiration of the Option. Any Related Right that relates to an Incentive Stock Option must be granted at the same time the Incentive Stock Option is granted. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Stock Appreciation Rights shall be made, the number of Shares to be awarded, the price per Share, and all other conditions of Stock Appreciation Rights. Notwithstanding the foregoing, no Related Right may be granted for more Shares than are subject to the Option to which it relates and any Stock Appreciation Right must be granted with an Exercise Price not less than the Fair Market Value of a Share on the date of grant. The provisions of Stock Appreciation Rights need not be the same with respect to each Participant. Stock Appreciation Rights granted under the Plan shall be subject to the following terms and conditions set forth in this Section 8 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable, as set forth in the applicable Award Agreement.

(b) Awards; Rights as Stockholder. The prospective recipient of a Stock Appreciation Right shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Participants who are granted Stock Appreciation Rights shall have no rights as stockholders of the Company with respect to the grant or exercise of such rights.

(c) Exercisability.

(i) Stock Appreciation Rights that are Free Standing Rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Stock Appreciation Rights that are Related Rights shall be exercisable only at such time or times and to the extent that the Options to which they relate shall be exercisable in accordance with the provisions of Section 7 above and this Section 8 of the Plan.

(d) Payment Upon Exercise.

(i) Upon the exercise of a Free Standing Right, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the price per share specified in the Free Standing Right multiplied by the number of Shares in respect of which the Free Standing Right is being exercised.

(ii) A Related Right may be exercised by a Participant by surrendering the applicable portion of the related Option. Upon such exercise and surrender, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of

C-265

the Fair Market Value as of the date of exercise over the Exercise Price specified in the related Option multiplied by the number of Shares in respect of which the Related Right is being exercised. Options which have been so surrendered, in whole or in part, shall no longer be exercisable to the extent the Related Rights have been so exercised.

(iii) Notwithstanding the foregoing, the Administrator may determine to settle the exercise of a Stock Appreciation Right in cash (or in any combination of Shares and cash).

(e) Termination of Employment or Service.

(i) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Free Standing Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Related Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as set forth in the related Options.

(f) Term.

(i) The term of each Free Standing Right shall be fixed by the Administrator, but no Free Standing Right shall be exercisable more than ten (10) years after the date such right is granted.

(ii) The term of each Related Right shall be the term of the Option to which it relates, but no Related Right shall be exercisable more than ten (10) years after the date such right is granted.

(g) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Stock Appreciation Rights shall be subject to Section 12 of the Plan.

(h) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Stock Appreciation Right outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. The Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 8(h) shall not apply to a Stock Appreciation Right if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Stock Appreciation Right with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 8(h).

Section 9. Restricted Shares.

(a) General. Each Award of Restricted Shares granted under the Plan shall be evidenced by an Award Agreement. Restricted Shares may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Shares shall be made; the number of Shares to be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares; the Restricted Period, if any, applicable to Restricted Shares; the Performance Goals (if any) applicable to Restricted Shares; and all other conditions of the Restricted Shares. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Shares in accordance with the terms of the grant. The terms and conditions applicable to the Restricted Shares need not be the same with respect to each Participant.

C-266

(b) Awards and Certificates. The prospective recipient of Restricted Shares shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Except as otherwise provided in herein, (i) each Participant who is granted an Award of Restricted Shares may, in the Company’s sole discretion, be issued a stock certificate in respect of such Restricted Shares; and (ii) any such certificate so issued shall be registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to any such Award. The Company may require that the stock certificates, if any, evidencing Restricted Shares granted hereunder be held in the custody of the Company until the restrictions thereon shall have lapsed, and that, as a condition of any award of Restricted Shares, the Participant shall have delivered a stock power, endorsed in blank, relating to the Shares covered by such Award. Notwithstanding anything in the Plan to the contrary, any Restricted Shares (whether before or after any vesting conditions have been satisfied) may, in the Company’s sole discretion, be issued in uncertificated form pursuant to the customary arrangements for issuing shares in such form.

(c) Restrictions and Conditions. The Restricted Shares granted pursuant to this Section 9 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or thereafter:

(i) The Restricted Shares shall be subject to the restrictions on transferability set forth in the Award Agreement and in the Plan.

(ii) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(iii) Subject to this Section 9(c)(ii), the Participant shall generally have the rights of a stockholder of the Company with respect to Restricted Shares during the Restricted Period. In the Administrator’s discretion and as provided in the applicable Award Agreement, a Participant may be entitled to dividends or dividend equivalents on an Award of Restricted Shares, which will be payable in accordance with the terms of such grant as determined by the Administrator in accordance with Section 18 of the Plan. Certificates for unrestricted Shares may, in the Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without forfeiture in respect of such Restricted Shares, except as the Administrator, in its sole discretion, shall otherwise determine.

(iv) The rights of Participants granted Restricted Shares upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Shares shall be subject to Section 12 of the Plan.

Section 10. Restricted Stock Units.

(a) General. Restricted Stock Units may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Stock Units shall be made; the number of Restricted Stock Units to be awarded; the Restricted Period, if any, applicable to Restricted Stock Units; the Performance Goals (if any) applicable to Restricted Stock Units; and all other conditions of the Restricted Stock Units. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Stock Units in accordance with the terms of the grant. The provisions of Restricted Stock Units need not be the same with respect to each Participant.

C-267

(b) Award Agreement. The prospective recipient of Restricted Stock Units shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Restrictions and Conditions. The Restricted Stock Units granted pursuant to this Section 10 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or, subject to Code Section 409A, thereafter:

(i) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(ii) Participants holding Restricted Stock Units shall have no voting rights. A Restricted Stock Unit may, at the Administrator’s discretion, carry with it a right to dividend equivalents, subject to Section 18 of the Plan. Such right would entitle the holder to be credited with an amount equal to all cash dividends paid on one Share while the Restricted Stock Unit is outstanding. The Administrator, in its discretion, may grant dividend equivalents from the date of grant or only after a Restricted Stock Unit is vested.

(iii) The rights of Participants granted Restricted Stock Units upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Settlement of Restricted Stock Units. Settlement of vested Restricted Stock Units shall be made to Participants in the form of Shares, unless the Administrator, in its sole discretion, provides for the payment of the Restricted Stock Units in cash (or partly in cash and partly in Shares) equal to the value of the Shares that would otherwise be distributed to the Participant.

(e) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Stock Units shall be subject to Section 12 of the Plan.

Section 11. Other Share-Based or Cash-Based Awards.

(a) The Administrator is authorized to grant Awards to Participants in the form of Other Share-Based Awards or Other Cash-Based Awards, as deemed by the Administrator to be consistent with the purposes of the Plan and as evidenced by an Award Agreement. The Administrator shall determine the terms and conditions of such Awards, consistent with the terms of the Plan, at the date of grant or thereafter, including any Performance Goals and performance periods. Shares or other securities or property delivered pursuant to an Award in the nature of a purchase right granted under this Section 11 shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, Shares, other Awards, notes or other property, as the Administrator shall determine, subject to any required corporate action.

(b) The prospective recipient of an Other Share-Based Award or Other Cash-Based Award shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Other Share-Based Awards and Other Cash-Based Awards shall be subject to Section 12 of the Plan.

C-268

Section 12. Change in Control.

The Administrator may provide in the applicable Award Agreement that an Award will vest on an accelerated basis upon the Participant’s termination of employment or service in connection with a Change in Control or upon the occurrence of any other event that the Administrator may set forth in the Award Agreement. If the Company is a party to an agreement that is reasonably likely to result in a Change in Control, such agreement may provide for: (i) the continuation of any Award by the Company, if the Company is the surviving corporation; (ii) the assumption of any Award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any Award, provided, however, that any such substitution with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A; or (iv) settlement of any Award for the Change in Control Price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the Change in Control Price or if the Administrator determines that Award cannot reasonably become vested pursuant to its terms, such Award shall terminate and be canceled without consideration. To the extent that Restricted Shares, Restricted Stock Units or other Awards settle in Shares in accordance with their terms upon a Change in Control, such Shares shall be entitled to receive as a result of the Change in Control transaction the same consideration as the Shares held by stockholders of the Company as a result of the Change in Control transaction. For purposes of this Section 12, “Change in Control Price” shall mean (A) the price per Share paid to stockholders of the Company in the Change in Control transaction, or (B) the Fair Market Value of a Share upon a Change in Control, as determined by the Administrator. To the extent that the consideration paid in any such Change in Control transaction consists all or in part of securities or other non-cash consideration, the value of such securities or other non-cash consideration shall be determined in good faith by the Administrator.

Section 13. Amendment and Termination.

(a) The Board or the Committee may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would adversely alter or impair the rights of a Participant under any Award theretofore granted without such Participant’s prior written consent.

(b) Notwithstanding the foregoing, (i) approval of the Company’s stockholders shall be obtained for any amendment that would require such approval in order to satisfy the requirements of Code Section 422, if applicable, any rules of the stock exchange on which the Shares are traded or other applicable law, and (ii) without stockholder approval to the extent required by the rules of any applicable national securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, except as otherwise permitted under Section 5 of the Plan, (A) no amendment or modification may reduce the Exercise Price of any Option or Stock Appreciation Right, (B) the Administrator may not cancel any outstanding Option or Stock Appreciation Right and replace it with a new Option or Stock Appreciation Right, another Award or cash and (C) the Administrator may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer quotation system.

(c) Subject to the terms and conditions of the Plan and Code Section 409A, the Administrator may modify, extend or renew outstanding Awards under the Plan, or accept the surrender of outstanding Awards (to the extent not already exercised) and grant new Awards in substitution of them (to the extent not already exercised).

(d) Notwithstanding the foregoing, no alteration, modification or termination of an Award will, without the prior written consent of the Participant, adversely alter or impair any rights or obligations under any Award already granted under the Plan.

Section 14. Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. Neither the Company, the Board nor the Committee shall be required to establish any special or separate fund or to segregate any assets to

C-269

assure the performance of its obligations under the Plan. With respect to any payments not yet made or Shares not yet transferred to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general unsecured creditor of the Company.

Section 15. Deferrals of Payment.

To the extent permitted by applicable law, the Administrator, in its sole discretion, may determine that the delivery of Shares or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award, shall be deferred. The Administrator may also, in its sole discretion, establish one or more programs under the Plan to permit selected Participants the opportunity to elect to defer receipt of any such consideration, including any applicable election procedures, the timing of such elections, the mechanisms for payments of amounts, shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program. Deferrals by Participants (or deferred settlement or payment required by the Administrator) shall be made in accordance with Code Section 409A, if applicable, and any other applicable law.

Section 16. Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for federal, state and/or local income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind, domestic or foreign, required by law or regulation to be withheld with respect to the Award. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award granted hereunder, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any federal, state and local withholding tax requirements related thereto. Whenever Shares are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related federal, state and local taxes, domestic or foreign, to be withheld and applied to the tax obligations. With the approval of the Administrator, a Participant may satisfy the foregoing requirement by electing to have the Company withhold from delivery of Shares or by delivering already owned unrestricted Shares, in each case, having a value equal to the amount required to be withheld or other greater amount not exceeding the maximum statutory rate required to be collected on the transaction under applicable law, as applicable to the Participant, if such other greater amount would not, as determined by the Administrator, result in adverse financial accounting treatment (including in connection with the effectiveness of FASB Accounting Standards Update 2016-09). Such Shares shall be valued at their Fair Market Value on the date of which the amount of tax to be withheld is determined. Fractional share amounts shall be settled in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant to an Award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Option or other Award (including by a “net exercise” or broker assisted “cashless” exercise procedure approved by the Administrator).

Section 17. Certain Forfeitures.

The Administrator may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain events, in addition to the applicable vesting conditions of an Award. Such events may include, without limitation, breach of any non-competition, non-solicitation, confidentiality, or other restrictive covenants that are contained in an Award Agreement or that are otherwise applicable to the Participant, a termination of the Participant’s employment for Cause, or other conduct by the Participant that is detrimental to the business or reputation of the Company and its Subsidiaries and/or its Affiliates.

C-270

Section 18. Dividends; Dividend Equivalents.

Notwithstanding anything in this Plan to the contrary, to the extent that an Award contains a right to receive dividends or dividend equivalents while such Award remains unvested, such dividends or dividend equivalents will be accumulated and paid once and to the extent that the underlying Award vests, and forfeited to the extent the underlying Award is forfeited.

Section 19. Non-United States Employees.

Without amending the Plan, the Administrator may grant Awards to eligible persons residing in non-United States jurisdictions on such terms and conditions different from those specified in the Plan, including the terms of any award agreement or plan, adopted by the Company or any Subsidiary thereof to comply with, or take advantage of favorable tax or other treatment available under, the laws of any non-United States jurisdiction, as may in the judgment of the Administrator be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in furtherance of such purposes the Administrator may make such modifications, amendments, procedures, sub-plans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Subsidiaries operates or has employees.

Section 20. Transfer of Awards.

No purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator, and other than by will or by the laws of descent and distribution. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio, and shall not create any obligation or liability of the Company, and any person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a holder of such Shares. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative. Under no circumstances will a Participant be permitted to transfer an Option or Stock Appreciation Right to a third-party financial institution without prior stockholder approval.

Section 21. Continued Employment.

The adoption of the Plan shall not confer upon any Eligible Recipient any right to continued employment or service with the Company or an Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or an Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time.

Section 22. Effective Date.

The Plan will be effective as of the date of consummation of the transactions contemplated by that certain business combination agreement, dated as of July 15, 2021, by and among Altimar Acquisition Corp. II, a Cayman Islands corporation, Fathom HoldCo LLC, a Delaware limited liability company and such other parties to the agreement as set forth therein and as subject to approval by the Company’s stockholders (the “Effective Date”). The Plan will be unlimited in duration and, in the event of Plan termination, will remain in effect as long as any Shares awarded under it are outstanding and not fully vested; provided, however, that no Awards will be made under the Plan on or after the tenth anniversary of the Effective Date.

C-271

Section 23. Code Section 409A.

The intent of the parties is that payments and benefits under the Plan be either exempt from Code Section 409A or comply with Code Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered consistent with such intent. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Code Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required in order to avoid accelerated taxation and/or tax penalties under Code Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon a “separation from service” to a Participant who is a “specified employee” shall be paid on the first business day after the date that is six (6) months following the Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, for purposes of the Plan, each amount to be paid or benefit to be provided to the Participant pursuant to the Plan, which constitute deferred compensation subject to Code Section 409A, shall be construed as a separate identified payment for purposes of Code Section 409A. Nothing contained in the Plan or an Award Agreement shall be construed as a guarantee of any particular tax effect with respect to an Award. The Company does not guarantee that any Awards provided under the Plan will be exempt from or in compliance with the provisions of Code Section 409A, and in no event will the Company be liable for any or all portion of any taxes, penalties, interest or other expenses that may be incurred by a Participant on account of any Award being subject to, but not in compliance with, Code Section 409A.

Section 24. Compliance with Laws.

(a) The obligation of the Company to settle Awards in Shares or other consideration shall be subject to (i) all applicable laws, rules, and regulations, (ii) such approvals as may be required by governmental agencies or the applicable national securities exchange on which the Shares may be admitted, and (iii) policies maintained by the Company from time to time in order to comply with applicable laws, rules, regulations and corporate governance requirements, including, without limitation, with respect to insider trading restrictions. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any Shares pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such Shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the Shares to be offered or sold under the Plan. The Administrator shall have the authority to provide that all Shares or other securities of the Company issued under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted and any other applicable federal, state, local or non-U.S. laws, rules, regulations and other requirements, and the Administrator may cause a legend or legends to be put on certificates representing Shares or other securities of the Company issued under the Plan to make appropriate reference to such restrictions or may cause such Shares or other securities of the Company issued under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it, in its sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

(b) The Administrator may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of Shares from the public markets, the Company’s issuance of Shares to the Participant, the Participant’s acquisition of Shares from the Company and/or the Participant’s sale of Shares to the public

C-272

markets, illegal, impracticable or inadvisable. If the Administrator determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply with Code Section 409A, (i) pay to the Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the Shares subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the Shares would have been vested or issued, as applicable), over (B) the aggregate Exercise Price (in the case of an Option or Stock Appreciation Right) or any amount payable as a condition of issuance of Shares (in the case of any other Award), and such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof, or (ii) in the case of Restricted Shares, Restricted Stock Units or Other Share-Based Awards, provide the Participant with a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Shares, Restricted Stock Units or Other Share-Based Awards, or the underlying Shares in respect thereof.

Section 25. No Interference.

The existence of the Plan, any Award Agreement, and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company, the Board, the Committee, or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization, or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, warrants, or rights to purchase stock or of bonds, debentures, or preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or that are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of the Company or any Affiliate, or any sale or transfer of all or any part of their assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

Section 26. Erroneously Awarded Compensation; Clawback.

The Plan and all Awards issued hereunder shall be subject to any compensation recovery and/or recoupment policy adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or to comport with good corporate governance practices, including on a retroactive basis, as such policies may be amended from time to time. Notwithstanding anything to the contrary contained herein, the Administrator also may cancel an Award if the Participant, without the consent of the Company, (a) has engaged in or engages in activity that is in conflict with or adverse to the interests of the Company or any Affiliate while employed by or providing services to the Company or any Affiliate, including fraud or conduct contributing to any financial restatements or irregularities or (b) violates a non-competition, non-solicitation, non-disparagement or non-disclosure covenant or agreement with the Company or any Affiliate, as determined by the Administrator, or if the Participant’s employment or service is terminated for Cause. The Administrator may also provide in an Award Agreement that in any such event the Participant will forfeit any compensation, gain or other value realized thereafter on the vesting, exercise or settlement of such Award, the sale or other transfer of such Award, or the sale of shares of Common Stock acquired in respect of such Award, and must promptly repay such amounts to the Company. The Administrator may also provide in an Award Agreement that if the Participant receives any amount in excess of what the Participant should have received under the terms of the Award for any reason (including without limitation by reason of a financial restatement, mistake in calculations or other administrative error), all as determined by the Administrator, then the Participant shall be required to promptly repay any such excess amount to the Company. In addition, the Company shall retain the right to bring an action at equity or law to enjoin the Participant’s activity and recover damages resulting from such activity.

Section 27. Whistleblower Acknowledgements.

Notwithstanding anything to the contrary herein, nothing in this Plan or any Award Agreement will (a) prohibit a Participant from making reports of possible violations of federal law or regulation to any

C-273

governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the Exchange Act or Section 806 of the Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of federal law or regulation, or (b) require prior approval by the Company or any of its Affiliates of any reporting described in clause (a).

Section 28. Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law of such state.

Section 29. Plan Document Controls.

The Plan and each Award Agreement together constitute the entire agreement with respect to the subject matter hereof and thereof; provided, that in the event of any inconsistency between the Plan and such Award Agreement, the terms and conditions of the Plan shall control.

C-274

C-277

have committed to provide equity financing solely for purposes of consummating the Transactions in the aggregate amount of $80,000,000 plus the amount of the CORE PIPE Investment of up to $10,000,000, if any (such aggregate amount, the “PIPE Investment Amount”). To the knowledge of Altimar, with respect to each PIPE Investor, the PIPE Subscription Agreement with such PIPE Investor is in full force and effect and has not been withdrawn or terminated, or otherwise amended, modified or waived, in any respect, and no withdrawal, termination, amendment or modification is contemplated by Altimar. Each PIPE Subscription Agreement is a legal, valid and binding obligation of Altimar and, to the knowledge of Altimar, each PIPE Investor, and neither the execution or delivery by Altimar nor the performance of Altimar’s obligations under any such PIPE Subscription Agreement violates any Laws. The PIPE Subscription Agreements provide that Altimar is a party thereto and is entitled to enforce such agreements against the PIPE Investor. There are no other agreements, side letters, or arrangements between Altimar and any PIPE Investor relating to any PIPE Subscription Agreement that could affect the obligation of such PIPE Investors to contribute to Altimar the applicable portion of the PIPE Investment Amount set forth in the PIPE Subscription Agreement of such PIPE Investor, and, as of the Execution Date (or, in the case of the CORE Subscription Agreement, on the date of execution and delivery thereof), Altimar does not know of any facts or circumstances that would reasonably be expected to result in any of the conditions set forth in any PIPE Subscription Agreement not being satisfied, or the PIPE Investment Amount not being available to Altimar, on the Closing Date. As of the Execution Date (or, in the case of the CORE Subscription Agreement, on the date of execution and delivery thereof), no event has occurred that, with or without notice, lapse of time or both, would constitute a default or breach on the part of Altimar under any material term or condition of any PIPE Subscription Agreement that it will be unable to satisfy in all material respects on a timely basis any term or condition of closing to be satisfied by it contained in any PIPE Subscription Agreement. The PIPE Subscription Agreements contain all of the conditions precedent (other than the conditions contained in the other Transaction Agreements) to the obligations of the PIPE Investors to contribute to Company the applicable portion of the PIPE Investment Amount set forth in the PIPE Subscription Agreements on the terms therein.

(o) Section 11.03(b) is hereby amended and restated in entirety to read as follows:

Available Closing Date Cash Amount. The Available Cash Amount shall not be less than $90,000,000.

2. Miscellaneous. The terms, conditions and provisions of the Business Combination Agreement, as amended by this Amendment, remain in full force and effect. The execution, delivery and effectiveness of this Amendment shall not operate as a waiver of any right, power or remedy of any Party under the Business Combination Agreement, nor constitute a waiver or amendment of any provision of the Business Combination Agreement. This Amendment shall be governed by, and otherwise construed in accordance with, the terms of the Business Combination Agreement, as though the other provisions of this Amendment were set forth in the Business Combination Agreement. This Amendment may be executed in counterparts (including by means of facsimile or scanned and emailed signature pages), any one of which need not contain the signatures of more than one Party, but all such counterparts taken together shall constitute one and the same agreement.

(b) In the event that CORE Designator has nominated less than the total number of designees that CORE Designator is entitled to nominate pursuant to Section 2.2(a), CORE Designator shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action, to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable CORE Designator to nominate and effect the election or appointment of such additional individuals, whether by increasing the size of the Board, or otherwise and (y) to designate such additional individuals nominated by CORE Designator to fill such newly created vacancies or to fill any other existing vacancies.

(c) In addition to the nomination rights set forth in Section 2.2(a) above, from the Effective Date, for so long as the CORE Investors Beneficially Own shares of Common Stock representing at least 5% of the Original Amount, CORE Designator shall have the right, but not the obligation, to designate a person (a “Non-Voting Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting

C-293

observer capacity. Any such Non-Voting Observer shall be permitted to attend all meetings of the Board. CORE Designator shall have the right to remove and replace its Non-Voting Observer at any time and from time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to Directors and (ii) copies of any materials prepared for meetings of the Board that are furnished to the Directors no later than the time such materials are furnished to the Directors; provided, that (x) such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality agreements of the Company generally applicable to directors of the Company or as the Company reasonably requests and (y) the Company reserves the right to withhold any information and to exclude such Non-Voting Observer from any meeting or portion thereof to the extent access to such materials or attendance at such meeting would be reasonably likely to adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest; provided, further, that failure to deliver notice, or materials, to such Non-Voting Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not, by itself, impair the validity of any action taken by such Board at such meeting.

(d) The Company shall pay all reasonable out-of-pocket expenses incurred by the CORE Nominees and the Non-Voting Observer in connection with the performance of his or her duties as a Director or a Non-Voting Observer and in connection with his or her attendance at any meeting of the Board. In addition, as promptly as practicable following the request by any CORE Nominee who is serving as a Director, the Company shall enter into an indemnification agreement with such CORE Nominee in the form entered into with the other members of the Board.

(e) No reduction in the number of shares of Common Stock that the CORE Investors Beneficially Own shall shorten the term of any incumbent director who is serving as a CORE Nominee.

(f) In the event that any CORE Nominee shall cease to serve for any reason, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate such person’s successor in accordance with this Agreement and the Board shall promptly fill the vacancy with such successor nominee; it being understood that any such designee shall serve the remainder of the term of the director whom such designee replaces.

(g) If a CORE Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate promptly another nominee and the director position for which the original CORE Nominee was nominated shall not be filled pending such designation.

(h) So long as CORE Designator has the right to nominate CORE Nominees under Section 2.2(a) or any such CORE Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage in an amount determined by the Board to be reasonable and customary, and the Company Charter and Amended and Restated Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification, exculpation and advancement of expenses to the fullest extent permitted under applicable law. Upon the removal or resignation of any CORE Nominee as a Director for any reason, the Company shall use commercially reasonable efforts to take all actions reasonably necessary to extend such director’s official liability insurance coverage for a period of not less than six (6) years from any such event in respect or any act or omission occurring at or prior to such event.

(i) If the size of the Board is expanded, CORE Designator shall be entitled to nominate a number of CORE Nominees to fill the newly created vacancies such that the total number of CORE Nominees serving on the Board following such expansion will be equal to that number of CORE Nominees that CORE Designator would be entitled to nominate in accordance with Section 2.2(a) if such expansion occurred immediately prior to

C-294

any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall appoint such CORE Nominees to the Board.

(j) During such time as the Company is required by applicable law or the New York Stock Exchange or such other principal United States securities exchange on which the Class A Common Stock is listed, quoted, or admitted to trading (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable phase-in periods), CORE Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other “independent directors” then serving on the Board that are not CORE Nominees, the Board is comprised of a majority of “independent directors.”

(k) At any time that CORE Designator shall have any nomination rights under Section 2.2, except as required by Law or the rules and regulations of the Exchange, the Company shall not take any action, including making or recommending any amendment to the Company Charter or the Company’s Amended and Restated Bylaws that could reasonably be expected to adversely affect CORE Designator’s rights, respectively, under this Agreement, in each case without the prior written consent of CORE Designator.

(l) Any CORE Nominee will be subject to the Company’s customary due diligence process, including its review of a completed questionnaire and a background check. Based on the foregoing, the Company may object to any CORE Nominee if (a) it does so in good faith and (b) such objection is based upon any of the following: (i) such CORE Nominee was convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses); (ii) such CORE Nominee was the subject of any order, judgment, or decree not subsequently reversed, suspended or vacated of any court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice; or (B) engaging in any activity in connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws; (iii) such CORE Nominee was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated, of any federal or state authority barring, suspending or otherwise limiting for more than sixty (60) days the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such activity; (iv) such CORE Nominee was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission has not been subsequently reversed, suspended or vacated; (v) such CORE Nominee was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree or finding, not subsequently reversed, suspended or vacated, relating to a violation of any federal or state securities laws or regulations; or (vi) any other reason(s) that apply by reason of applicable Law, the rules and regulations of the Exchange or Company policy. In the event the Board reasonably finds the CORE Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (vi) and reasonably objects to the identified director, the CORE Designator shall be entitled to propose a different CORE Nominee to the Board within thirty (30) calendar days of the Company’s notice to the CORE Designator of its objection to the CORE Nominee and such replacement CORE Nominee shall be subject to the review process outlined above.

2.3 Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date that the CORE Investors cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each CORE Nominee is included in the Board’s slate of nominees to the stockholders (the “Board Slate”) for each election of directors; and (ii) each CORE Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. CORE Designator will promptly provide reporting to the Company after CORE Designator ceases to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, such that Company is informed of when this

C-295

obligation terminates. The calculation of the number of CORE Nominees that CORE Designator is entitled to nominate to the Board Slate for any election of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by CORE (“CORE Voting Control”), as applicable, immediately prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission). Unless CORE Designator notifies the Company otherwise prior to the mailing to stockholders of the Director Election Proxy Statement relating to an election of directors, the CORE Nominees for such election shall be presumed to be the same CORE Nominees currently serving on the Board, and no further action shall be required of CORE Designator for the Board to include such CORE Nominees on the Board’s Slate; provided, that, in the event CORE Designator is no longer entitled to nominate the full number of CORE Nominees then serving on the Board, CORE Designator shall provide advance written notice to the Company, of which currently serving CORE Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of CORE Nominees. If CORE Designator fails to provide such notice prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then serving on the Board shall determine which of the CORE Nominees of CORE Designator then serving on the Board will be included in the Board Slate.

2.4 Compensation. Except to the extent any CORE Designator may otherwise notify the Company with respect to such CORE Designator’s CORE Nominees, each CORE Nominee shall be entitled to compensation consistent with the Director compensation received by other Directors, including any fees and equity awards.

2.5 Other Rights of CORE Nominees. Except as provided in Section 2.3, each CORE Nominee serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of the foregoing, the Company shall, to the maximum extent permitted by applicable Law, indemnify, exculpate, and reimburse fees and expenses of the CORE Nominees (including by entering into an indemnification agreement in a form substantially similar to the Company’s form director indemnification agreement) and provide the CORE Nominees with director and officer insurance to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the Company Charter or Amended and Restated Bylaws of the Company, applicable Law or otherwise.

2.6 Director Independence. Notwithstanding anything to the contrary herein, the parties hereto shall ensure the composition of the Board will continue to meet all requirements for a company listed on the New York Stock Exchange (or such other stock exchange on which the Class A Common Stock may be listed from time to time), including with respect to director independence.

REGISTRATIONS AND OFFERINGS

2.1.1 Filing. The Company shall file within 30 days of the Closing Date, and use commercially reasonable efforts to cause to be declared effective as soon as practicable thereafter, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a Shelf Registration on Form S¬3 (the “Form S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on a delayed or

C-312

continuous basis. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3 and, in any event, within 10 days following such date.

2.1.2 Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

2.1.3 Additional Registerable Securities. In the event that any Investor holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a CORE Investor or any Sponsor Investor, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, the Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof.

2.1.4 Requests for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf is on file with the Commission, any CORE Investor or any Sponsor Investor (any of such Investors being, in such case, a “Demanding Investor”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other coordinated offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the Demanding Investor with a total offering price reasonably expected to exceed, in the aggregate, $50 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. The Demanding Investor initiating the request shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval (which shall not be unreasonably withheld, conditioned or delayed). Notwithstanding anything to the contrary in this Section 2.1.4 and this Agreement, there shall be no limit to the number of Underwritten Shelf Takedowns that may be requested by any Demanding Investor. Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten

C-313

Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

2.1.5 Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Investors and the Investors requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Investors”) (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Investors and the Requesting Investors (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, before including any shares of Common Stock or other equity securities proposed to be sold by Company or by other holders of Common Stock or other equity securities the following: (i) first, the Registrable Securities of the Demanding Investors and the Requesting Investors (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Investor and Requesting Investor (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities that the Demanding Investors and Requesting Investors have requested be included in such Underwritten Shelf Takedown) that can be sold without exceeding the Maximum Number of Securities, (ii) second, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i), the Common Stock or other equity securities that Company desires to sell, which can be sold without exceeding the Maximum Number of Securities and (iii) third, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i) and 2.1.5 (ii), the Common Stock or other equity securities of any other Investor or any other person that Company is obligated to include in such Underwritten Offering pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities. To facilitate the allocation of Registrable Securities in accordance with the above provisions, the Company or the Underwriters may round the number of shares allocated to any Investor to the nearest 100 shares. The Company shall not be required to include any Registrable Securities in such Underwritten Shelf Takedown unless the Investors accept the terms of the underwriting as agreed upon between the Company and its Underwriters.

2.1.6 Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, a majority-in-interest of the Demanding Investors initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided that any Core Investor or a Sponsor Investor may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by such Investors or any of their respective Permitted Transferees, as applicable. If withdrawn, a demand for an Underwritten Shelf Takedown shall not constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Investors that had elected to participate in such Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6.

In connection with any Shelf and/or Shelf Takedown, the Company shall use its commercially reasonable efforts to effect such Registration to permit the sale of such Registrable Securities in accordance with the intended plan of distribution thereof, and pursuant thereto the Company shall, as expeditiously as possible:

3.1.1 prepare and file with the Commission as soon as practicable a Registration Statement with respect to such Registrable Securities and use its reasonable best efforts to cause such Registration Statement to become effective and remain effective until all Registrable Securities have ceased to be Registrable Securities;

3.1.2 prepare and file with the Commission such amendments and post-effective amendments to the Registration Statement, and such supplements to the Prospectus, as may be reasonably requested by any Investor or as may be required by the rules, regulations or instructions applicable to the registration form used by the Company or by the Securities Act or rules and regulations thereunder to keep the Registration Statement effective until all Registrable Securities covered by such Registration Statement are sold in accordance with the intended plan of distribution set forth in such Registration Statement or supplement to the Prospectus;

3.1.3 prior to filing a Registration Statement or Prospectus, or any amendment or supplement thereto, furnish without charge to the Underwriters, if any, and the Investors of Registrable Securities included in such Registration, and such Investors’ legal counsel, copies of such Registration Statement as proposed to be filed, each amendment and supplement to such Registration Statement (in each case including all exhibits thereto and documents incorporated by reference therein), the Prospectus included in such Registration Statement (including each preliminary Prospectus), and such other documents as the Underwriters and the Investors of Registrable Securities included in such Registration or the legal counsel for any such Investors may request in order to facilitate the disposition of the Registrable Securities owned by such Investors;

C-317

3.1.4 prior to any public offering of Registrable Securities (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Investors of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request (or provide evidence satisfactory to such Investors that the Registrable Securities are exempt from such registration or qualification) and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Investors of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.5 cause all such Registrable Securities to be listed on each national securities exchange on which similar securities issued by the Company are then listed;

3.1.6 provide a transfer agent or warrant agent, as applicable, and registrar for all such Registrable Securities no later than the effective date of such Registration Statement;

3.1.7 advise each seller of such Registrable Securities, promptly after it shall receive notice or obtain knowledge thereof, of the issuance of any stop order by the Commission suspending the effectiveness of such Registration Statement or the initiation or threatening of any proceeding for such purpose and promptly use its reasonable best efforts to prevent the issuance of any stop order or to obtain its withdrawal if such stop order should be issued;

3.1.8 at least five (5) days prior to the filing of any Registration Statement or Prospectus or any amendment or supplement to such Registration Statement or Prospectus (or such shorter period of time as may be necessary in order to comply with the Securities Act, the Exchange Act, and the rules and regulations promulgated under the Securities Act or Exchange Act, as applicable), furnish a copy thereof to each seller of such Registrable Securities or its counsel (excluding any exhibits thereto and any filing made under the Exchange Act that is to be incorporated by reference therein);

3.1.9 notify the Investors at any time when a Prospectus relating to such Registration Statement is required to be delivered under the Securities Act, of the happening of any event as a result of which the Prospectus included in such Registration Statement, as then in effect, includes a Misstatement, and then to correct such Misstatement as set forth in Section 3.4 hereof;

3.1.10 permit a representative of the Investors, the Underwriters, if any, and any attorney or accountant retained by such Investors or Underwriter to participate, at each such person’s own expense, in the preparation of the Registration Statement, and cause the Company’s officers, directors and employees to supply all information reasonably requested by any such representative, Underwriter, attorney or accountant in connection with the Registration; provided, however, that such representatives or Underwriters agree to confidentiality arrangements reasonably satisfactory to the Company, prior to the release or disclosure of any such information;

3.1.11 obtain a “comfort” letter from the Company’s independent registered public accountants in the event of an Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, in customary form and covering such matters of the type customarily covered by “comfort” letters as the managing Underwriter or other similar type of sales agent or placement agent may reasonably request, and reasonably satisfactory to a majority-in-interest of the participating Investors;

3.1.12 on the date the Registrable Securities are delivered for sale pursuant to such Registration, obtain an opinion, dated such date, of counsel representing the Company for the purposes of such Registration,

C-318

addressed to the Investors, the placement agent or sales agent, if any, and the Underwriters, if any, covering such legal matters with respect to the Registration in respect of which such opinion is being given as the Investors, placement agent, sales agent, or Underwriter may reasonably request and as are customarily included in such opinions and negative assurance letters, and reasonably satisfactory to a majority-in-interest of the participating Investors;

3.1.13 in the event of any Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, enter into and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary form, with the managing Underwriter, sales agent or placement agent of such offering;

3.1.14 make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect);

3.1.15 if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million with respect to an Underwritten Offering pursuant to Section 2.1.4, use its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.16 otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investors, in connection with such Registration.

Notwithstanding the foregoing, the Company shall not be required to provide any documents or information to an Underwriter or other sales agent or placement agent if such Underwriter or other sales agent or placement agent has not then been named with respect to the applicable Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement.

3.2 Registration Expenses. The Registration Expenses of all Registrations shall be borne by the Company. It is acknowledged by the Investors that the Investors shall bear all incremental selling expenses relating to the sale of Registrable Securities, such as Underwriters’ or agents’ commissions and discounts, brokerage fees, Underwriter marketing costs and, other than as set forth in the definition of “Registration Expenses,” all reasonable fees and expenses of any legal counsel representing the Investors.

3.3 Requirements for Participation in Registration Statement Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Investor does not provide the Company with its requested Investor Information, the Company may exclude such Investor’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the registration and such Investor continues thereafter to withhold such information. No person may participate in any Underwritten Offering or other coordinated offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such arrangements. The exclusion of an Investor’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

3.4 Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1 Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Investors shall forthwith discontinue disposition of Registrable Securities

C-319

until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.4.2 If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the majority of the Board such Registration, be seriously detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Investors, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.4.2, the Investors agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

3.4.3 (a) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated Registration and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf Registration Statement, or (b) if, pursuant to Section 2.1.4, Investors have requested an Underwritten Shelf Takedown and the Company and such Investors are unable to obtain the commitment of underwriters to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Investors, delay any other registered offering pursuant to Section 2.1.4 or 2.4. Notwithstanding anything to the contrary contained in this Agreement and except for the obligations set forth in Section 2.1.1 and Section 2.2.2, no Registration shall be effected or permitted, no Registration Statement shall become effective, and no notice shall be refused to be delivered with respect to any Registrable Securities held by any Investor, until after the expiration of the Lock-Up Period applicable to the securities.

3.5 Reporting Obligations. As long as any Investor shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Investors with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Investors pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Investor may reasonably request, all to the extent required from time to time to enable such Investor to sell shares of Common Stock held by such Investor without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Investor, the Company shall deliver to such Investor a written certification of a duly authorized officer as to whether it has complied with such requirements.

ARTICLE IV

INDEMNIFICATION AND CONTRIBUTION

4.1 Indemnification.

4.1.1 The Company agrees to indemnify, to the extent permitted by law, each Investor of Registrable Securities, its officers, directors and agents and each person who controls such Investor (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without

C-320

limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Investor expressly for use therein.

4.1.2 In connection with any Registration Statement in which an Investor of Registrable Securities is participating, such Investor shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Investor Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Investor expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Investors of Registrable Securities, and the liability of each such Investor of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Securities pursuant to such Registration Statement. The Investors of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3 Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4 The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each Investor of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Investor’s indemnification is unavailable for any reason.

4.1.5 If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the

C-321

indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Investor under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Investor in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

5.5.2 EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY ACTION BASED UPON, ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Following the Closing Date, within ninety (90) calendar days after the filing of the Form 1120 (or any successor form) of the Corporation for any Taxable Year, the Corporation shall provide to the TRA Party Representative a schedule showing, in reasonable detail, the calculation of the Tax Benefit Payment in respect of each TRA Party for such Taxable Year and the calculation of the Realized Tax Benefit and Realized Tax Detriment and the components thereof for such Taxable Year (a “Tax Benefit Schedule”). Each Tax Benefit Schedule will become final as provided in Section 2.3(a) and may be amended as provided in Section 2.3(b) (subject to the procedures set forth in Section 2.3(b)).

(b) Applicable Principles. For purposes of calculating the Realized Tax Benefit or Realized Tax Detriment for any period, carryovers or carrybacks of any Tax item attributable to the Blocker Pre-BCA Covered Tax Assets and the Exchange Covered Tax Assets shall be considered to be subject to the rules of the Code and the Treasury Regulations, as applicable, or other applicable law, governing the use, limitation and expiration of carryovers or carrybacks of the relevant type. If a carryover or carryback of any Tax item includes a portion that is attributable to a Blocker Pre-BCA Covered Tax Asset or an Exchange Covered Tax Asset and another portion that is not, such respective portions shall be considered to be used in accordance with the “with and without” methodology.

Section 2.3. Procedures, Amendments.

(a) Procedure. Every time the Corporation delivers to the TRA Party Representative a Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.3(b), and any Early Termination Schedule or amended Early Termination Schedule, the Corporation shall also deliver schedules, valuation reports, if any, and work papers, as determined by the Corporation or reasonably requested by the TRA Party Representative, providing reasonable detail regarding the preparation of the Schedule, and allow the TRA Party Representative reasonable access at no cost to the appropriate representatives of the Corporation, as determined by the Corporation or requested by the TRA Party Representative, in connection with the review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporation delivers to the TRA Party Representative a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporation shall also deliver to the TRA Party Representative a reasonably detailed calculation of the applicable Hypothetical Tax Liability, a reasonably detailed calculation of the applicable Actual Tax Liability, as well as any other work papers considered relevant by the Corporation or requested by the TRA Party Representative, provided that the Corporation shall not be required to provide any information that it reasonably believes is unnecessary for purposes of determining the items in the applicable Schedule or amendment thereto. Subject to Section 2.3(b), an applicable Schedule or amendment thereto shall become final and binding on all parties thirty (30) calendar days after the first date on which the TRA Party Representative has received the applicable Schedule or amendment thereto unless (i) the TRA Party Representative provides the Corporation before such date with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) the TRA Party Representative provides a written waiver of such right of any Objection Notice before such date (in which case such Schedule or amendment thereto becomes binding on the date such waiver has been received by the Corporation). If the Corporation and the TRA Party Representative, for any reason, are unable to successfully resolve the issues raised in an Objection Notice within thirty (30) calendar days after receipt by the Corporation of an Objection Notice, then the Corporation and the TRA Party Representative shall employ the reconciliation procedures described in Section 7.8 of this Agreement (the “Reconciliation Procedures”).

(b) Amended Schedule. The applicable Attribute Schedule or Tax Benefit Schedule for any Taxable Year may be amended from time to time by the Corporation (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified after the date the Schedule was provided to the TRA Party Representative, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, or (v) to reflect a

C-344

change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year (any such Schedule, an “Amended Schedule”). The Corporation shall provide to the TRA Party Representative an Amended Schedule, along with reasonable detail regarding the preparation of the applicable portion of such Amended Schedule, within sixty (60) calendar days of the occurrence of an event referenced in clauses (i) through (v) of the first sentence of this Section 2.3(b).

ARTICLE III.

TAX BENEFIT PAYMENTS

Section 3.1. Timing and Amount of Tax Benefit Payments.

(a) Within five (5) Business Days after a Tax Benefit Schedule delivered to the TRA Party Representative becomes final in accordance with Section 2.3(a), the Corporation shall pay or cause to be paid to each TRA Party for such Taxable Year an amount equal to the excess, if any, of (i) the Tax Benefit Payment in respect of such TRA Party for such Taxable Year determined pursuant to Section 3.1(b) over (ii) the aggregate amount of Advance Payments previously made to such TRA Party in respect of such Taxable Year; provided that, if the Corporation makes Advance Payments, it shall make Advance Payments to all parties eligible to receive payments under this Agreement with respect to a particular Taxable Year in proportion to their respective amount of anticipated payments under this Agreement in respect of such Taxable Year. Each such Tax Benefit Payment or such Advance Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such TRA Party to the Corporation or as otherwise agreed by the Corporation and such TRA Party. The Corporation shall use its commercially reasonable efforts to respond to any reasonable inquiry of a TRA Party in regard to the calculation of the amount payable to such TRA Party pursuant to any Schedule delivered under this Agreement, including the calculation of the Tax Benefit Payment in respect of such TRA Party for such Taxable Year.

(b) A “Tax Benefit Payment” in respect of a TRA Party means an amount, not less than zero, equal to the sum of the portion of the Net Tax Benefit that is Attributable to such TRA Party and the Interest Amount with respect thereto. A Net Tax Benefit is “Attributable” to a Blocker TRA Party to the extent that it is derived from a Blocker Pre-BCA Covered Tax Asset with respect to a Blocker. A Net Tax Benefit is “Attributable” to an Exchange TRA Party to the extent that it is derived from an Exchange Covered Tax Asset with respect to Company Units that were Exchanged by such TRA Party. The “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the sum of the total amount of payments previously made under Section 3.1(a) (excluding payments attributable to Interest Amounts) and the Advance Payments previously made under Section 3.1(b) of this Agreement (excluding any portion of Advance Payments in respect of anticipated Interest Amounts); provided, for the avoidance of doubt, that a TRA Party shall not be required to return any portion of any previously made Tax Benefit Payment or Advance Payment it receives under this Agreement. The “Interest Amount” in respect of the TRA Party shall equal the interest on the amount of the unpaid Net Tax Benefit Attributable to such TRA Party for a Taxable Year, which interest shall accrue on any unpaid Net Tax Benefit from and after the due date (without extensions) for filing the IRS Form 1120 (or any successor form) for the Corporation for such Taxable Year, calculated at the Agreed Rate, until the date such unpaid amounts are paid. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but instead shall be treated as additional consideration in the Business Combination or an Exchange, as applicable, unless otherwise required by law. “Advance Payments” in respect of a TRA Party for a Taxable Year means the payments made by the Corporation to such TRA Party as an advance of such TRA Party’s anticipated Tax Benefit Payment for such Taxable Year. The Corporation shall be entitled at its option with the approval of a majority of the Independent Directors to make Advance Payments. Notwithstanding anything to the contrary in this Agreement, after any lump-sum payment under Article IV of this Agreement in respect of present or future Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets, such Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets shall no longer be considered Blocker Pre-BCA Covered Tax Assets or

C-345

Exchange Covered Tax Assets, as applicable, for purposes of determining Tax Benefit Payments or the Net Tax Benefit.

Section 3.2. No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed consistent with such intent.

Section 3.3. Pro Rata Payments.

(a) Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate amount of the tax benefit to the Corporation from the reduction in Tax liability as a result of the Blocker Pre-BCA Covered Tax Assets or the Exchange Covered Tax Assets is limited in a particular Taxable Year because the Corporation does not have sufficient taxable income to fully utilize available deductions and other attributes, the aggregate Net Tax Benefit for such Taxable Year shall be deemed Attributable to each TRA Party for purposes of Section 3.1(b) in proportion to the portion of such Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) if the Corporation had sufficient taxable income so that there were no such limitation; provided, that, for the avoidance of doubt, for purposes of allocating among the TRA Parties the aggregate Net Tax Benefit with respect to any Taxable Year, the operation of this Section 3.3(a) with respect to any prior Taxable Years shall be taken into account so as to eliminate as quickly as possible, proportionately, the difference with respect to each TRA Party between (i) the aggregate Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) if the Corporation had sufficient taxable income so that there were no limitation under this Section 3.3(a) and (ii) the actual aggregate Net Tax Benefit deemed Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) by operation of this this Section 3.3(a). Consistent with the foregoing, the Attribute Schedule for a given Taxable Year shall reflect the operation of this Section 3.3(a) in respect of previous Taxable Years, with the Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets described in such Attribute Schedule that are Attributable to a TRA Party being adjusted to reflect payments received in respect of such Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets (the intention of the parties being to avoid duplicative payments and maintain records sufficient to allow the Corporation to allocate Tax Benefit Payments consistent with the terms of this Section 3.3(a)).

(b) After taking into account Section 3.3(a), if for any reason the Corporation does not fully satisfy its payment obligations to make Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year (for example, as a result of having insufficient cash to make the Tax Benefit Payments due hereunder), then the Corporation and the TRA Parties agree that (i) the Corporation shall make payments due hereunder to the TRA Parties in respect of a Taxable Year in the same proportion as such payments would have been made if the relevant payment had been made in full by the Corporation, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been paid.

(c) To the extent the Corporation makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account Sections 3.3(a) and (b)) in an amount in excess of the amount of such payment that should have been made to the TRA Party in respect of such Taxable Year, then (i) the TRA Party shall not receive further payments under Section 3.1(a) until the TRA Party has forgone an amount of payments equal to such excess and (ii) the Corporation shall pay the amount of the TRA Party’s forgone payments to other TRA Parties (to the extent applicable) in a manner such that each of the other TRA Parties, to the extent possible, shall have received aggregate payments under Sections 3.1(a) and (b) in the amount it would have received if there had been no excess payment to the TRA Party.

Section 3.4. Withholding. The Corporation and its affiliates and representatives shall be entitled to deduct and withhold from any payment that is payable to any TRA Party pursuant to this Agreement such amounts as are required to be deducted or withheld with respect to the making of such payment in accordance with the Code or any provision of U.S. state, local or foreign tax law (including for this purpose any withholding required by

C-346

the Corporation or its affiliates that may be required in connection with an Exchange). To the extent that amounts are so deducted or withheld and promptly paid over to the appropriate Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid by the Corporation to the relevant TRA Party. The Corporation shall provide evidence of such payment to each TRA Party in respect of which such deduction or withholding is required, to the extent that such evidence is available. Each TRA Party shall promptly provide the Corporation with any applicable tax forms and certifications reasonably requested by the Corporation in connection with determining whether any such deductions and withholdings are required under the Code or any provision of U.S. state, local or foreign tax law. The Corporation will consider in good faith any applicable certificates, forms or documentation provided by a TRA Party that in such TRA Party’s reasonable determination reduce or eliminate any such withholding.

ARTICLE IV.

TERMINATION

Section 4.1. Early Termination of Agreement; Breach of Agreement.

(a) With the prior written approval of the Board (or any Person(s) to whom the Board has delegated such authority), the Corporation may terminate this Agreement with respect to all amounts payable to the TRA Parties at any time by paying to each TRA Party the Early Termination Payment in respect of the TRA Party; provided, however, that (i) this Agreement shall only terminate pursuant to this Section 4.1(a) upon the receipt in full of the Early Termination Payment by the TRA Parties, (ii) the Corporation shall deliver an Early Termination Notice only if it is able to make all required Early Termination Payments under this Agreement, and (iii) the Corporation may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid.

(b) In the event that the Corporation breaches any of its material obligations under this Agreement, whether as a result of a failure to make any payment when due, a failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, and the Corporation fails to cure such breach within 20 Business Days of the TRA Party Representative informing the Corporation of such breach, then, at the election of the TRA Party Representative, all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach. Procedures similar to the procedures of Section 4.2 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation pursuant to this Section 4.1(b). Notwithstanding the foregoing, in the event that the Corporation breaches any of its material obligations under this Agreement, the TRA Party Representative shall be entitled to elect on behalf of all TRA Parties to receive the amounts referred to in this Section 4.1(b) or to seek specific performance of the terms of this Agreement. The parties agree that the failure to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3) months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of a material obligation of this Agreement if the Corporation fails to make any Tax Benefit Payment when due to the extent that the Corporation has insufficient funds to make such payment; provided, (i) the Corporation has used reasonable efforts to obtain such funds (including by causing the Company or any other Subsidiaries of the Company to distribute or lend funds to facilitate such payment, and by accessing any revolving credit facilities or other sources of available credit to fund any such amounts) and (ii) that the interest provisions of Section 5.3 shall apply to such late payment (unless the Corporation does not have sufficient funds to make such payment as a result of limitations imposed by any Senior Obligations, in which case Section 5.3 shall apply, but the Default Rate shall be replaced by the Agreed Rate).

(c) In connection with a Change of Control, all obligations under this Agreement with respect to the applicable TRA Parties shall be accelerated and such obligations shall be calculated as if an Early Termination

C-347

Notice had been delivered on the closing date of the Change of Control. Section 4.2 and Section 4.3 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation.

Section 4.2. Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1(a) above, the Corporation shall deliver to the TRA Party Representative written notice of such intention to exercise such right (“Early Termination Notice”). In addition, if the Corporation chooses to exercise its right of early termination under Section 4.1(a) above, or the obligations under this Agreement are accelerated under Section 4.1(b) or Section 4.1(c) above, the Corporation shall deliver to the TRA Party Representative a schedule (the “Early Termination Schedule”) showing in reasonable detail the calculation of the Early Termination Payment due to each TRA Party. Such Early Termination Schedule shall become final and binding on all parties consistent with the procedures described in Section 2.3(a). The date on which the Early Termination Schedule becomes final shall be the “Early Termination Effective Date.”

Section 4.3. Payment upon Early Termination.

(a) Within three (3) calendar days after an Early Termination Effective Date, the Corporation shall pay to the TRA Parties an amount equal to the Early Termination Payment in respect of such TRA Party; provided, however, that any amount payable pursuant to this Agreement as a result of a Change of Control shall be paid concurrently with the consummation of such Change of Control. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the TRA Party or as otherwise agreed by the Corporation and such TRA Party.

(b) “Early Termination Payment” in respect of a TRA Party shall equal (i) the present value, discounted at the Early Termination Rate, as of the date of the Early Termination Notice, of all Tax Benefit Payments in respect of such TRA Party that would be required to be paid by the Corporation beginning from the date of the Early Termination Notice and assuming that the Valuation Assumptions in respect of such TRA Party are applied and that each such Tax Benefit Payment for each relevant Taxable Year would be paid on the due date (including extensions) under applicable law as of the Early Termination Date for filing of IRS Form 1120 (or any successor form) of the Corporation for each such Taxable Year, plus (ii) any Tax Benefit Payment due and payable with respect to such TRA Party that is unpaid as of the date of the Early Termination Notice.

(c) Upon the payment of the Early Termination Payment by the Corporation to a TRA Party, the Corporation shall not have any further payment obligations under this Agreement in respect of such TRA Party.

ARTICLE V.

SUBORDINATION; CERTAIN TAX COVENANTS; LATE PAYMENTS

Section 5.1. Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment or Early Termination Payment required to be made by the Corporation under this Agreement shall rank subordinate and junior in right of payment to any principal, interest, or other amounts due and payable in respect of any obligations owed in respect of secured or unsecured indebtedness for borrowed money of the Corporation and its Subsidiaries (“Senior Obligations”) and shall rank pari passu in right of payment with all current or future unsecured obligations of the Corporation that are not Senior Obligations. To the extent that any payment under this Agreement is not permitted to be made at the time payment is due as a result of this Section 5.1 and the terms of the agreements governing Senior Obligations, such payment obligation nevertheless shall accrue for the benefit of the applicable TRA Parties and the Corporation shall make such payments at the first opportunity that such payments are permitted to be made in accordance with the terms of the Senior Obligations (it being understood that interest shall accrue on the amount of such unpaid obligation in accordance with the terms hereof). Payments under any tax receivable agreement or similar agreement (excluding, for the avoidance of doubt, this Agreement) entered into after the date hereof or as part of any transaction entered into after the date hereof in which the Corporation, the Company or their Subsidiaries would be required to pay the

C-348

parties thereto for tax attributes shall be subordinate to all payments owed pursuant to this Agreement, and no such payments shall be made for so long as the Corporation has any current unpaid obligation pursuant this Agreement. The Corporation shall use its commercially reasonable efforts to maintain sufficient available funds for the purpose of making required payments under this Agreement and avoid entering into credit agreements or Senior Obligations that could be reasonably anticipated to materially delay the timing of any payments under this Agreement.

Section 5.2. Certain Tax Covenants.

(a) The Corporation hereby agrees and warrants to each TRA Party (i) that it will not cause the Company or any material Subsidiary of the Company to convert into, or elect to be treated as, a corporation for Tax purposes without the prior written consent of the TRA Party Representative, (ii) that it will not cause the Company to contribute any of its material assets into one or more Subsidiaries that are treated as corporations for Tax purposes, or cause the Company to liquidate or distribute in kind any of its material non-cash assets to its members, without the prior written consent of the TRA Party Representative, and (iii) that it will cause the Company, and any material Subsidiary that is treated as a partnership for Tax purposes, to make valid Section 754 elections (and all comparable elections under applicable state and local tax law) for its first Taxable Year ending after the date of this Agreement and it will not seek to revoke any such election until the Corporation has received all material tax benefits from all Exchange Party Basis Adjustments and Imputed Interest in respect of which the Corporation may be required to make any payments under this Agreement to the TRA Parties.

(b) The Corporation hereby agrees that prior to (i) any proposed Interest Sale (as defined in Section 5.2(c)) or (ii) any proposed sale or other disposition of all or any substantial part of the non-cash assets of the Company, it shall deliver to each TRA Party notice of such proposed transaction at least thirty (30) days prior to the consummation thereof and afford each TRA Party that still holds Company Units the opportunity to Exchange all or part of such Company Units prior to such date.

(c) For purposes of this Agreement, (i) any sale or other disposition of all or any part of the Corporation’s interest in the Company (an “Interest Sale”) shall be deemed to be comprised of a sale or other disposition of a pro rata portion of each of the separate interests held by the Corporation (i.e., the original interest of the Corporation as of the date of this Agreement and each additional interest acquired hereafter by Exchange or otherwise), regardless of whether such separate interests can be (or are) identified and separately conveyed, and (ii) notwithstanding any provision herein to the contrary, for purposes of determining the payments due to the TRA Parties hereunder attributable to such Interest Sale, each such separate interest that was acquired from a TRA Party pursuant to an Exchange shall be treated as a Reference Asset and the Exchange Party Basis Adjustment with respect thereto shall be the excess of the Tax basis of the Corporation in such interest immediately after such Exchange over the Tax basis of such TRA Party in the applicable Company Units immediately before such Exchange (with such Exchange Party Basis Adjustment to be increased as appropriate to reflect payments by the Corporation to such TRA Party pursuant to this Agreement and to be decreased as appropriate to reflect the depreciation or amortization attributable to the correlative Exchange Party Basis Adjustments to the underlying assets of the Company).

Section 5.3. Late Payments by the Corporation. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment or other payment under this Agreement not made to the TRA Parties when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment, Early Termination Payment or other payment was due and payable.

C-349

ARTICLE VI.

TAX MATTERS; CONSISTENCY; COOPERATION

Section 6.1. Participation in the Corporation’s and the Company’s Tax Matters. Except as otherwise provided in this Agreement, the Business Combination Agreement or the Company LLC Agreement, the Corporation shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporation, the Company and their Subsidiaries, including the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing,

(i) the Corporation shall notify the TRA Party Representative in writing of the commencement of, and keep the TRA Party Representative reasonably informed with respect to, the portion of any audit of the Corporation, the Company or any of their Subsidiaries by a Taxing Authority the outcome of which would reasonably be expected to materially affect the rights and obligations of a TRA Party under this Agreement, including the Tax Benefit Payments payable to TRA Parties,

(ii) shall provide to the TRA Party Representative reasonable opportunity (at the cost and expense of the TRA Party Representative, on behalf of the TRA Parties) to participate in or provide information and other input to the Corporation, the Company and their Subsidiaries, as applicable, and their respective advisors concerning the conduct of any such portion of such audit, which the Corporation, the Company and their Subsidiaries (including their advisors) shall consider in good faith; and

(iii) the Corporation, the Company and their Subsidiaries, as applicable, shall not enter into any settlement with respect to any such portion of such audit that could have a material adverse effect on the TRA Parties’ rights to receive payments under this Agreement without the written consent of the TRA Party Representative, such consent not to be unreasonably withheld, conditioned or delayed.

Section 6.2. Reconciliation. In the event that the Corporation and the TRA Party Representative are unable to resolve a disagreement with respect to a Schedule (a “Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to such parties. The Expert shall be a partner or principal in a nationally recognized accounting firm. If the Corporation and the TRA Party Representative are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the selection of an Expert shall be treated as a dispute subject to Section 7.8 and an arbitration panel shall pick an Expert. The Expert shall resolve any matter relating to a Schedule or an amendment thereto as soon as reasonably practicable and in any event within thirty (30) calendar days after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporation, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporation except as provided in the next sentence. The Corporation and the TRA Party Representative shall bear their own costs and expenses of such proceeding, unless (i) the Expert entirely adopts the position of the TRA Party Representative, in which case the Corporation shall reimburse the TRA Party Representative for any reasonable and documented out-of-pocket costs and expenses in such proceeding, or (ii) the Expert entirely adopts the Corporation’s position, in which case Tax Benefit Payments to the TRA Parties that would have increased Tax Benefit Payments if the position of the TRA Party Representative had been adopted shall be reduced proportionately in the aggregate by any reasonable and documented out-of-pocket costs and expenses in such proceeding. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 6.2 shall be binding on the Corporation and the TRA Parties and may be entered and enforced in any court having competent jurisdiction.

Section 6.3. Consistency. The Corporation and the TRA Parties agree to report and cause to be reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related

C-350

items (including, without limitation, the Exchange Party Basis Adjustments, Blocker Party Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that specified in any Schedule finalized consistent with the terms of this Agreement, unless otherwise required by a contrary Determination by an applicable Taxing Authority.

Section 6.4. Cooperation. Each of the Corporation, the Company and the TRA Parties shall (a) furnish to the other parties in a timely manner such information, documents and other materials as the other party may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or defending any audit, examination or controversy with any Taxing Authority, (b) make itself reasonably available to the other parties and their respective representatives to provide explanations of documents and material and such other information as the other party or its representatives may reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and the Corporation shall reimburse each TRA Party for any reasonable third-party costs and expenses incurred pursuant to this Section 6.4 at the request of the Corporation or the Company.

Section 6.5. Tax Characterization. The parties intend that (a) each Exchange shall give rise to Exchange Party Basis Adjustments and (b) payments to Exchange TRA Parties pursuant to this Agreement with respect to an Exchange (except with respect to amounts that constitute Imputed Interest) shall be treated as consideration in respect of such Exchange that give rise to additional Exchange Party Basis Adjustments.

Section 6.6. Change in Tax Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in Tax law, a TRA Party reasonably believes that the existence of this Agreement could increase the amount of income (other than income arising from receipt of a payment under this Agreement) recognized by such TRA Party upon any Exchange which is treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income and all applicable state and local Tax purposes or would have other material adverse Tax consequences to the TRA Party and/or its direct or indirect owners, then at the election of such TRA Party and to the extent specified by the TRA Party, this Agreement (i) shall cease to have further effect with respect to such TRA Party, (ii) shall not apply to an Exchange by the TRA Party occurring after a date specified by it, or (iii) shall otherwise be amended in a manner determined by the TRA Party to waive any benefits to which such TRA Party would otherwise be entitled under this Agreement, provided that such amendment shall not result in an increase in or acceleration of payments under this Agreement at any time as compared to the amounts and times of payments that would have been due in the absence of such amendment or increase the Corporation’s administrative burden in complying with this Agreement.

No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporation and by TRA Parties who would be entitled to receive more than fifty percent (50%) of the aggregate amount of the Early Termination Payments payable to all TRA Parties hereunder if the Corporation had exercised its right of Early Termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Party pursuant to this Agreement since the date of such most recent Exchange); provided, however, that no such amendment shall be effective if such amendment would have a disproportionate effect on the payments certain TRA Parties will or may receive under this Agreement unless all such disproportionately affected TRA Parties consent in writing to such amendment; provided, further, that amendment of the definition of Change of Control or any approval rights granted to the Independent Directors will also require the written approval of a majority of the Independent Directors.

The Corporation shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place.

(d) Waiver. Neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No party shall be deemed to have waived any claim arising out of this Agreement, or any right, remedy, power or privilege under this Agreement, unless the waiver of such claim, right, remedy, power or privilege is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

(c) (i) EACH TRA PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN THE STATE OF DELAWARE FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF SECTION 7.8(B), OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT.

Section 7.9. Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER OR RELATE TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE BREACH OR VALIDITY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

         Section 7.10. Confidentiality. Each TRA Party and its assignees acknowledges and agrees that the information of the Corporation and its Affiliates provided pursuant to this Agreement is confidential and, except in the course of performing any duties as necessary for the Corporation and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such Person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters of the Corporation and its Affiliates and successors acquired pursuant to this Agreement. This Section 7.10 shall not apply to (i) any information that has been made publicly available by the Corporation, becomes public knowledge (except as a result of an act of any

C-354

TRA Party in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to the extent necessary for a TRA Party to prosecute or defend claims arising under or relating to this Agreement, (iii) the disclosure of information to the extent necessary for a TRA Party to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such Tax Returns, and (iv) the disclosure to any potential assignee or transferee of information in connection with an assignment, sale, pledge, alienation or transfer of any interest in this Agreement pursuant to Section 7.6(a) so long as such potential assignee or transferee agrees to be subject to the provisions of this Section 7.10. Notwithstanding anything to the contrary in this Agreement, to the extent required by applicable law or to the extent reasonably necessary for a TRA Party to comply with any applicable reportable transaction requirements under applicable law, each TRA Party (and each employee, representative or other agent of the TRA Party, as applicable) may disclose the Tax treatment and Tax structure of the Corporation, the Company and their Subsidiaries, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that are provided to the TRA Party relating to such Tax treatment and Tax structure.

Section 7.11. Interest Rate Limitation. Notwithstanding anything to the contrary contained herein, the interest paid or agreed to be paid hereunder with respect to amounts due to any TRA Party hereunder shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If any TRA Party shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the Tax Benefit Payment, Advance Payment or Early Termination Payment, as applicable (but in each case exclusive of any component thereof comprising interest) or, if it exceeds such unpaid non-interest amount, refunded to the Corporation. In determining whether the interest contracted for, charged, or received by any TRA Party exceeds the Maximum Rate, such TRA Party may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the payment obligations owed by the Corporation to such TRA Party hereunder. Notwithstanding the foregoing, it is the intention of the parties hereto to conform strictly to any applicable usury laws.

Section 7.12. Independent Nature of Rights and Obligations.

(a) The rights and obligations of the each TRA Party hereunder are several and not joint with the rights and obligations of any other Person. A TRA Party shall not be responsible in any way for the performance of the obligations of any other Person hereunder, nor shall a TRA Party have the right to enforce the rights or obligations of any other Person hereunder (other than the Corporation). Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any TRA Party pursuant hereto or thereto, shall be deemed to constitute the TRA Parties acting as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the TRA Parties are in any way acting in concert or as a group with respect to such rights or obligations or the transactions contemplated hereby, and the Corporation acknowledges that the TRA Parties are not acting in concert or as a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated hereby.

(b) Except as otherwise explicitly provided in this Agreement, the actions of a TRA Party pursuant to and in accordance with this Agreement shall be binding only with respect to such TRA Party and not with respect to the any other TRA Party. To the fullest extent permitted by law, no TRA Party shall owe any duties (fiduciary or otherwise) to any other TRA Party or any other Person in determining to take or refrain from taking any action or decision under or in connection with this Agreement.

Section 2.3.    Procedures, Amendments.

(a)    Procedure. Every time the Corporation delivers to the TRA Party Representative a Schedule under this Agreement, including any Amended Schedule delivered pursuant to Section 2.3(b), and any Early Termination Schedule or amended Early Termination Schedule, the Corporation shall also deliver schedules, valuation reports, if any, and work papers, as determined by the Corporation or reasonably requested by the TRA Party Representative, providing reasonable detail regarding the preparation of the Schedule, and allow the TRA Party Representative reasonable access at no cost to the appropriate representatives of the Corporation, as determined by the Corporation or requested by the TRA Party Representative, in connection with the review of such Schedule. Without limiting the application of the preceding sentence, each time the Corporation delivers to the TRA Party Representative a Tax Benefit Schedule, in addition to the Tax Benefit Schedule duly completed, the Corporation shall also deliver to the TRA Party Representative a reasonably detailed calculation of the applicable Hypothetical Tax Liability, a reasonably detailed calculation of the applicable Actual Tax Liability, as well as any other work papers considered relevant by the Corporation or requested by the TRA Party Representative, provided that the Corporation shall not be required to provide any information that it reasonably believes is unnecessary for purposes of determining the items in the applicable Schedule or amendment thereto. Subject to Section 2.3(b), an applicable Schedule or amendment thereto shall become final and binding on all parties thirty (30) calendar days after the first date on which the TRA Party Representative has received the applicable Schedule or amendment thereto unless (i) the TRA Party Representative provides the Corporation before such date with notice of a material objection to such Schedule (“Objection Notice”) made in good faith or (ii) the TRA Party Representative provides a written waiver of such right of any Objection Notice before such date (in which case such Schedule or amendment thereto becomes binding on the date such waiver has been received by the Corporation). If the Corporation and the TRA Party Representative, for any reason, are unable to successfully resolve the issues raised in an Objection Notice within thirty (30) calendar days after receipt by the Corporation of an Objection Notice, then the Corporation and the TRA Party Representative shall employ the reconciliation procedures described in Section 7.8 of this Agreement (the “Reconciliation Procedures”).

(b)    Amended Schedule. The applicable Attribute Schedule or Tax Benefit Schedule for any Taxable Year may be amended from time to time by the Corporation (i) in connection with a Determination affecting such Schedule, (ii) to correct inaccuracies in the Schedule identified after the date the Schedule was provided to the TRA Party Representative, (iii) to comply with the Expert’s determination under the Reconciliation Procedures, (iv) to reflect a change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to a carryback or carryforward of a loss or other tax item to such Taxable Year, or (v) to reflect a

D-14

change in the Realized Tax Benefit or Realized Tax Detriment for such Taxable Year attributable to an amended Tax Return filed for such Taxable Year (any such Schedule, an “Amended Schedule”). The Corporation shall provide to the TRA Party Representative an Amended Schedule, along with reasonable detail regarding the preparation of the applicable portion of such Amended Schedule, within sixty (60) calendar days of the occurrence of an event referenced in clauses (i) through (v) of the first sentence of this Section 2.3(b).

ARTICLE III.

TAX BENEFIT PAYMENTS

Section 3.1.    Timing and Amount of Tax Benefit Payments.

(a)    Within five (5) Business Days after a Tax Benefit Schedule delivered to the TRA Party Representative becomes final in accordance with Section 2.3(a), the Corporation shall pay or cause to be paid to each TRA Party for such Taxable Year an amount equal to the excess, if any, of (i) the Tax Benefit Payment in respect of such TRA Party for such Taxable Year determined pursuant to Section 3.1(b) over (ii) the aggregate amount of Advance Payments previously made to such TRA Party in respect of such Taxable Year; provided that, if the Corporation makes Advance Payments, it shall make Advance Payments to all parties eligible to receive payments under this Agreement with respect to a particular Taxable Year in proportion to their respective amount of anticipated payments under this Agreement in respect of such Taxable Year. Each such Tax Benefit Payment or such Advance Payment shall be made by wire transfer of immediately available funds to the bank account previously designated by such TRA Party to the Corporation or as otherwise agreed by the Corporation and such TRA Party. The Corporation shall use its commercially reasonable efforts to respond to any reasonable inquiry of a TRA Party in regard to the calculation of the amount payable to such TRA Party pursuant to any Schedule delivered under this Agreement, including the calculation of the Tax Benefit Payment in respect of such TRA Party for such Taxable Year.

(b)    A “Tax Benefit Payment” in respect of a TRA Party means an amount, not less than zero, equal to the sum of the portion of the Net Tax Benefit that is Attributable to such TRA Party and the Interest Amount with respect thereto. A Net Tax Benefit is “Attributable” to a Blocker TRA Party to the extent that it is derived from a Blocker Pre-BCA Covered Tax Asset with respect to a Blocker. A Net Tax Benefit is “Attributable” to an Exchange TRA Party to the extent that it is derived from an Exchange Covered Tax Asset with respect to Company Units that were Exchanged by such TRA Party. The “Net Tax Benefit” for a Taxable Year shall be an amount equal to the excess, if any, of 85% of the Cumulative Net Realized Tax Benefit as of the end of such Taxable Year over the sum of the total amount of payments previously made under Section 3.1(a) (excluding payments attributable to Interest Amounts) and the Advance Payments previously made under Section 3.1(b) of this Agreement (excluding any portion of Advance Payments in respect of anticipated Interest Amounts); provided, for the avoidance of doubt, that a TRA Party shall not be required to return any portion of any previously made Tax Benefit Payment or Advance Payment it receives under this Agreement. The “Interest Amount” in respect of the TRA Party shall equal the interest on the amount of the unpaid Net Tax Benefit Attributable to such TRA Party for a Taxable Year, which interest shall accrue on any unpaid Net Tax Benefit from and after the due date (without extensions) for filing the IRS Form 1120 (or any successor form) for the Corporation for such Taxable Year, calculated at the Agreed Rate, until the date such unpaid amounts are paid. For the avoidance of doubt, for Tax purposes, the Interest Amount shall not be treated as interest but instead shall be treated as additional consideration in the Business Combination or an Exchange, as applicable, unless otherwise required by law. “Advance Payments” in respect of a TRA Party for a Taxable Year means the payments made by the Corporation to such TRA Party as an advance of such TRA Party’s anticipated Tax Benefit Payment for such Taxable Year. The Corporation shall be entitled at its option with the approval of a majority of the Independent Directors to make Advance Payments. Notwithstanding anything to the contrary in this Agreement, after any lump-sum payment under Article IV of this Agreement in respect of present or future Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets, such Blocker Pre-BCA Covered Tax Assets or Exchange Covered Tax Assets shall no longer be considered Blocker Pre-BCA Covered Tax Assets or

D-15

Exchange Covered Tax Assets, as applicable, for purposes of determining Tax Benefit Payments or the Net Tax Benefit.

Section 3.2.    No Duplicative Payments. It is intended that the provisions of this Agreement will not result in duplicative payment of any amount (including interest) required under this Agreement. The provisions of this Agreement shall be construed consistent with such intent.

Section 3.3.    Pro Rata Payments.

(a)    Notwithstanding anything in Section 3.1 to the contrary, to the extent that the aggregate amount of the tax benefit to the Corporation from the reduction in Tax liability as a result of the Blocker Pre-BCA Covered Tax Assets or the Exchange Covered Tax Assets is limited in a particular Taxable Year because the Corporation does not have sufficient taxable income to fully utilize available deductions and other attributes, the aggregate Net Tax Benefit for such Taxable Year shall be deemed Attributable to each TRA Party for purposes of Section 3.1(b) in proportion to the portion of such Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) if the Corporation had sufficient taxable income so that there were no such limitation; provided, that, for the avoidance of doubt, for purposes of allocating among the TRA Parties the aggregate Net Tax Benefit with respect to any Taxable Year, the operation of this Section 3.3(a) with respect to any prior Taxable Years shall be taken into account so as to eliminate as quickly as possible, proportionately, the difference with respect to each TRA Party between (i) the aggregate Net Tax Benefit that would be Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) if the Corporation had sufficient taxable income so that there were no limitation under this Section 3.3(a) and (ii) the actual aggregate Net Tax Benefit deemed Attributable to such TRA Party under Section 3.1(b) with respect to each such Taxable Year (on a cumulative basis) by operation of this this Section 3.3(a). Consistent with the foregoing, the Attribute Schedule for a given Taxable Year shall reflect the operation of this Section 3.3(a) in respect of previous Taxable Years, with the Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets described in such Attribute Schedule that are Attributable to a TRA Party being adjusted to reflect payments received in respect of such Blocker Pre-BCA Covered Tax Assets and Exchange Covered Tax Assets (the intention of the parties being to avoid duplicative payments and maintain records sufficient to allow the Corporation to allocate Tax Benefit Payments consistent with the terms of this Section 3.3(a)).

(b)    After taking into account Section 3.3(a), if for any reason the Corporation does not fully satisfy its payment obligations to make Tax Benefit Payments due under this Agreement in respect of a particular Taxable Year (for example, as a result of having insufficient cash to make the Tax Benefit Payments due hereunder), then the Corporation and the TRA Parties agree that (i) the Corporation shall make payments due hereunder to the TRA Parties in respect of a Taxable Year in the same proportion as such payments would have been made if the relevant payment had been made in full by the Corporation, and (ii) no Tax Benefit Payment shall be made in respect of any Taxable Year until all Tax Benefit Payments in respect of prior Taxable Years have been paid.

(c)    To the extent the Corporation makes a payment to a TRA Party in respect of a particular Taxable Year under Section 3.1(a) of this Agreement (taking into account Sections 3.3(a) and (b)) in an amount in excess of the amount of such payment that should have been made to the TRA Party in respect of such Taxable Year, then (i) the TRA Party shall not receive further payments under Section 3.1(a) until the TRA Party has forgone an amount of payments equal to such excess and (ii) the Corporation shall pay the amount of the TRA Party’s forgone payments to other TRA Parties (to the extent applicable) in a manner such that each of the other TRA Parties, to the extent possible, shall have received aggregate payments under Sections 3.1(a) and (b) in the amount it would have received if there had been no excess payment to the TRA Party.

Section 3.4.    Withholding. The Corporation and its affiliates and representatives shall be entitled to deduct and withhold from any payment that is payable to any TRA Party pursuant to this Agreement such amounts as are required to be deducted or withheld with respect to the making of such payment in accordance with the Code or any provision of U.S. state, local or foreign tax law (including for this purpose any withholding required by

D-16

the Corporation or its affiliates that may be required in connection with an Exchange). To the extent that amounts are so deducted or withheld and promptly paid over to the appropriate Taxing Authority, such amounts shall be treated for all purposes of this Agreement as having been paid by the Corporation to the relevant TRA Party. The Corporation shall provide evidence of such payment to each TRA Party in respect of which such deduction or withholding is required, to the extent that such evidence is available. Each TRA Party shall promptly provide the Corporation with any applicable tax forms and certifications reasonably requested by the Corporation in connection with determining whether any such deductions and withholdings are required under the Code or any provision of U.S. state, local or foreign tax law. The Corporation will consider in good faith any applicable certificates, forms or documentation provided by a TRA Party that in such TRA Party’s reasonable determination reduce or eliminate any such withholding.

ARTICLE IV.

TERMINATION

Section 4.1.    Early Termination of Agreement; Breach of Agreement.

(a)    With the prior written approval of the Board (or any Person(s) to whom the Board has delegated such authority), the Corporation may terminate this Agreement with respect to all amounts payable to the TRA Parties at any time by paying to each TRA Party the Early Termination Payment in respect of the TRA Party; provided, however, that (i) this Agreement shall only terminate pursuant to this Section 4.1(a) upon the receipt in full of the Early Termination Payment by the TRA Parties, (ii) the Corporation shall deliver an Early Termination Notice only if it is able to make all required Early Termination Payments under this Agreement, and (iii) the Corporation may withdraw any notice to execute its termination rights under this Section 4.1(a) prior to the time at which any Early Termination Payment has been paid.

(b)    In the event that the Corporation breaches any of its material obligations under this Agreement, whether as a result of a failure to make any payment when due, a failure to honor any other material obligation required hereunder or by operation of law as a result of the rejection of this Agreement in a case commenced under the Bankruptcy Code or otherwise, and the Corporation fails to cure such breach within 20 Business Days of the TRA Party Representative informing the Corporation of such breach, then, at the election of the TRA Party Representative, all obligations hereunder shall be accelerated and such obligations shall be calculated as if an Early Termination Notice had been delivered on the date of such breach. Procedures similar to the procedures of Section 4.2 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation pursuant to this Section 4.1(b). Notwithstanding the foregoing, in the event that the Corporation breaches any of its material obligations under this Agreement, the TRA Party Representative shall be entitled to elect on behalf of all TRA Parties to receive the amounts referred to in this Section 4.1(b) or to seek specific performance of the terms of this Agreement. The parties agree that the failure to make any payment due pursuant to this Agreement within three (3) months of the date such payment is due shall be deemed to be a breach of a material obligation under this Agreement for all purposes of this Agreement, and that it will not be considered to be a breach of a material obligation under this Agreement to make a payment due pursuant to this Agreement within three (3) months of the date such payment is due. Notwithstanding anything in this Agreement to the contrary, it shall not be a breach of a material obligation of this Agreement if the Corporation fails to make any Tax Benefit Payment when due to the extent that the Corporation has insufficient funds to make such payment; provided, (i) the Corporation has used reasonable efforts to obtain such funds (including by causing the Company or any other Subsidiaries of the Company to distribute or lend funds to facilitate such payment, and by accessing any revolving credit facilities or other sources of available credit to fund any such amounts) and (ii) that the interest provisions of Section 5.3 shall apply to such late payment (unless the Corporation does not have sufficient funds to make such payment as a result of limitations imposed by any Senior Obligations, in which case Section 5.3 shall apply, but the Default Rate shall be replaced by the Agreed Rate).

(c)    In connection with a Change of Control, all obligations under this Agreement with respect to the applicable TRA Parties shall be accelerated and such obligations shall be calculated as if an Early Termination

D-17

Notice had been delivered on the closing date of the Change of Control. Section 4.2 and Section 4.3 shall apply, mutatis mutandis, with respect to the determination of the amounts payable by the Corporation.

Section 4.2.    Early Termination Notice. If the Corporation chooses to exercise its right of early termination under Section 4.1(a) above, the Corporation shall deliver to the TRA Party Representative written notice of such intention to exercise such right (“Early Termination Notice”). In addition, if the Corporation chooses to exercise its right of early termination under Section 4.1(a) above, or the obligations under this Agreement are accelerated under Section 4.1(b) or Section 4.1(c) above, the Corporation shall deliver to the TRA Party Representative a schedule (the “Early Termination Schedule”) showing in reasonable detail the calculation of the Early Termination Payment due to each TRA Party. Such Early Termination Schedule shall become final and binding on all parties consistent with the procedures described in Section 2.3(a). The date on which the Early Termination Schedule becomes final shall be the “Early Termination Effective Date.”

Section 4.3.    Payment upon Early Termination.

(a)    Within three (3) calendar days after an Early Termination Effective Date, the Corporation shall pay to the TRA Parties an amount equal to the Early Termination Payment in respect of such TRA Party; provided, however, that any amount payable pursuant to this Agreement as a result of a Change of Control shall be paid concurrently with the consummation of such Change of Control. Such payment shall be made by wire transfer of immediately available funds to a bank account or accounts designated by the TRA Party or as otherwise agreed by the Corporation and such TRA Party.

(b)    “Early Termination Payment” in respect of a TRA Party shall equal (i) the present value, discounted at the Early Termination Rate, as of the date of the Early Termination Notice, of all Tax Benefit Payments in respect of such TRA Party that would be required to be paid by the Corporation beginning from the date of the Early Termination Notice and assuming that the Valuation Assumptions in respect of such TRA Party are applied and that each such Tax Benefit Payment for each relevant Taxable Year would be paid on the due date (including extensions) under applicable law as of the Early Termination Date for filing of IRS Form 1120 (or any successor form) of the Corporation for each such Taxable Year, plus (ii) any Tax Benefit Payment due and payable with respect to such TRA Party that is unpaid as of the date of the Early Termination Notice.

(c)    Upon the payment of the Early Termination Payment by the Corporation to a TRA Party, the Corporation shall not have any further payment obligations under this Agreement in respect of such TRA Party.

ARTICLE V.

SUBORDINATION; CERTAIN TAX COVENANTS; LATE PAYMENTS

Section 5.1.    Subordination. Notwithstanding any other provision of this Agreement to the contrary, any Tax Benefit Payment or Early Termination Payment required to be made by the Corporation under this Agreement shall rank subordinate and junior in right of payment to any principal, interest, or other amounts due and payable in respect of any obligations owed in respect of secured or unsecured indebtedness for borrowed money of the Corporation and its Subsidiaries (“Senior Obligations”) and shall rank pari passu in right of payment with all current or future unsecured obligations of the Corporation that are not Senior Obligations. To the extent that any payment under this Agreement is not permitted to be made at the time payment is due as a result of this Section 5.1 and the terms of the agreements governing Senior Obligations, such payment obligation nevertheless shall accrue for the benefit of the applicable TRA Parties and the Corporation shall make such payments at the first opportunity that such payments are permitted to be made in accordance with the terms of the Senior Obligations (it being understood that interest shall accrue on the amount of such unpaid obligation in accordance with the terms hereof). Payments under any tax receivable agreement or similar agreement (excluding, for the avoidance of doubt, this Agreement) entered into after the date hereof or as part of any transaction entered into after the date hereof in which the Corporation, the Company or their Subsidiaries would

D-18

be required to pay the parties thereto for tax attributes shall be subordinate to all payments owed pursuant to this Agreement, and no such payments shall be made for so long as the Corporation has any current unpaid obligation pursuant this Agreement. The Corporation shall use its commercially reasonable efforts to maintain sufficient available funds for the purpose of making required payments under this Agreement and avoid entering into credit agreements or Senior Obligations that could be reasonably anticipated to materially delay the timing of any payments under this Agreement.

Section 5.2.    Certain Tax Covenants.

(a)    The Corporation hereby agrees and warrants to each TRA Party (i) that it will not cause the Company or any material Subsidiary of the Company to convert into, or elect to be treated as, a corporation for Tax purposes without the prior written consent of the TRA Party Representative, (ii) that it will not cause the Company to contribute any of its material assets into one or more Subsidiaries that are treated as corporations for Tax purposes, or cause the Company to liquidate or distribute in kind any of its material non-cash assets to its members, without the prior written consent of the TRA Party Representative, and (iii) that it will cause the Company, and any material Subsidiary that is treated as a partnership for Tax purposes, to make valid Section 754 elections (and all comparable elections under applicable state and local tax law) for its first Taxable Year ending after the date of this Agreement and it will not seek to revoke any such election until the Corporation has received all material tax benefits from all Exchange Party Basis Adjustments and Imputed Interest in respect of which the Corporation may be required to make any payments under this Agreement to the TRA Parties.

(b)    The Corporation hereby agrees that prior to (i) any proposed Interest Sale (as defined in Section 5.2(c)) or (ii) any proposed sale or other disposition of all or any substantial part of the non-cash assets of the Company, it shall deliver to each TRA Party notice of such proposed transaction at least thirty (30) days prior to the consummation thereof and afford each TRA Party that still holds Company Units the opportunity to Exchange all or part of such Company Units prior to such date.

(c)    For purposes of this Agreement, (i) any sale or other disposition of all or any part of the Corporation’s interest in the Company (an “Interest Sale”) shall be deemed to be comprised of a sale or other disposition of a pro rata portion of each of the separate interests held by the Corporation (i.e., the original interest of the Corporation as of the date of this Agreement and each additional interest acquired hereafter by Exchange or otherwise), regardless of whether such separate interests can be (or are) identified and separately conveyed, and (ii) notwithstanding any provision herein to the contrary, for purposes of determining the payments due to the TRA Parties hereunder attributable to such Interest Sale, each such separate interest that was acquired from a TRA Party pursuant to an Exchange shall be treated as a Reference Asset and the Exchange Party Basis Adjustment with respect thereto shall be the excess of the Tax basis of the Corporation in such interest immediately after such Exchange over the Tax basis of such TRA Party in the applicable Company Units immediately before such Exchange (with such Exchange Party Basis Adjustment to be increased as appropriate to reflect payments by the Corporation to such TRA Party pursuant to this Agreement and to be decreased as appropriate to reflect the depreciation or amortization attributable to the correlative Exchange Party Basis Adjustments to the underlying assets of the Company).

Section 5.3.    Late Payments by the Corporation. The amount of all or any portion of any Tax Benefit Payment, Early Termination Payment or other payment under this Agreement not made to the TRA Parties when due under the terms of this Agreement shall be payable together with any interest thereon, computed at the Default Rate and commencing from the date on which such Tax Benefit Payment, Early Termination Payment or other payment was due and payable.

D-19

ARTICLE VI.

TAX MATTERS; CONSISTENCY; COOPERATION

Section 6.1.    Participation in the Corporation’s and the Company’s Tax Matters. Except as otherwise provided in this Agreement, the Business Combination Agreement or the Company LLC Agreement, the Corporation shall have full responsibility for, and sole discretion over, all Tax matters concerning the Corporation, the Company and their Subsidiaries, including the preparation, filing or amending of any Tax Return and defending, contesting or settling any issue pertaining to Taxes. Notwithstanding the foregoing,

(i)    the Corporation shall notify the TRA Party Representative in writing of the commencement of, and keep the TRA Party Representative reasonably informed with respect to, the portion of any audit of the Corporation, the Company or any of their Subsidiaries by a Taxing Authority the outcome of which would reasonably be expected to materially affect the rights and obligations of a TRA Party under this Agreement, including the Tax Benefit Payments payable to TRA Parties,

(ii)    shall provide to the TRA Party Representative reasonable opportunity (at the cost and expense of the TRA Party Representative, on behalf of the TRA Parties) to participate in or provide information and other input to the Corporation, the Company and their Subsidiaries, as applicable, and their respective advisors concerning the conduct of any such portion of such audit, which the Corporation, the Company and their Subsidiaries (including their advisors) shall consider in good faith; and

(iii)    the Corporation, the Company and their Subsidiaries, as applicable, shall not enter into any settlement with respect to any such portion of such audit that could have a material adverse effect on the TRA Parties’ rights to receive payments under this Agreement without the written consent of the TRA Party Representative, such consent not to be unreasonably withheld, conditioned or delayed.

Section 6.2.    Reconciliation. In the event that the Corporation and the TRA Party Representative are unable to resolve a disagreement with respect to a Schedule (a “Reconciliation Dispute”), the Reconciliation Dispute shall be submitted for determination to a nationally recognized expert (the “Expert”) in the particular area of disagreement mutually acceptable to such parties. The Expert shall be a partner or principal in a nationally recognized accounting firm. If the Corporation and the TRA Party Representative are unable to agree on an Expert within fifteen (15) calendar days of receipt by the respondent(s) of written notice of a Reconciliation Dispute, the selection of an Expert shall be treated as a dispute subject to Section 7.8 and an arbitration panel shall pick an Expert. The Expert shall resolve any matter relating to a Schedule or an amendment thereto as soon as reasonably practicable and in any event within thirty (30) calendar days after the matter has been submitted to the Expert for resolution. Notwithstanding the preceding sentence, if the matter is not resolved before any payment that is the subject of a disagreement would be due (in the absence of such disagreement) or any Tax Return reflecting the subject of a disagreement is due, the undisputed amount shall be paid on the date prescribed by this Agreement and such Tax Return may be filed as prepared by the Corporation, subject to adjustment or amendment upon resolution. The costs and expenses relating to the engagement of such Expert or amending any Tax Return shall be borne by the Corporation except as provided in the next sentence. The Corporation and the TRA Party Representative shall bear their own costs and expenses of such proceeding, unless (i) the Expert entirely adopts the position of the TRA Party Representative, in which case the Corporation shall reimburse the TRA Party Representative for any reasonable and documented out-of-pocket costs and expenses in such proceeding, or (ii) the Expert entirely adopts the Corporation’s position, in which case Tax Benefit Payments to the TRA Parties that would have increased Tax Benefit Payments if the position of the TRA Party Representative had been adopted shall be reduced proportionately in the aggregate by any reasonable and documented out-of-pocket costs and expenses in such proceeding. The Expert shall finally determine any Reconciliation Dispute and the determinations of the Expert pursuant to this Section 6.2 shall be binding on the Corporation and the TRA Parties and may be entered and enforced in any court having competent jurisdiction.

Section 6.3.    Consistency. The Corporation and the TRA Parties agree to report and cause to be reported for all purposes, including federal, state and local Tax purposes and financial reporting purposes, all Tax-related

D-20

items (including, without limitation, the Exchange Party Basis Adjustments, Blocker Party Basis Adjustments and each Tax Benefit Payment) in a manner consistent with that specified in any Schedule finalized consistent with the terms of this Agreement, unless otherwise required by a contrary Determination by an applicable Taxing Authority.

Section 6.4.    Cooperation. Each of the Corporation, the Company and the TRA Parties shall (a) furnish to the other parties in a timely manner such information, documents and other materials as the other party may reasonably request for purposes of making any determination or computation necessary or appropriate under this Agreement, preparing any Tax Return or defending any audit, examination or controversy with any Taxing Authority, (b) make itself reasonably available to the other parties and their respective representatives to provide explanations of documents and material and such other information as the other party or its representatives may reasonably request in connection with any of the matters described in clause (a) above, and (c) reasonably cooperate in connection with any such matter, and the Corporation shall reimburse each TRA Party for any reasonable third-party costs and expenses incurred pursuant to this Section 6.4 at the request of the Corporation or the Company.

Section 6.5.    Tax Characterization. The parties intend that (a) each Exchange shall give rise to Exchange Party Basis Adjustments and (b) payments to Exchange TRA Parties pursuant to this Agreement with respect to an Exchange (except with respect to amounts that constitute Imputed Interest) shall be treated as consideration in respect of such Exchange that give rise to additional Exchange Party Basis Adjustments.

Section 6.6.    Change in Tax Law. Notwithstanding anything herein to the contrary, if, in connection with an actual or proposed change in Tax law, a TRA Party reasonably believes that the existence of this Agreement could increase the amount of income (other than income arising from receipt of a payment under this Agreement) recognized by such TRA Party upon any Exchange which is treated as ordinary income rather than capital gain (or otherwise taxed at ordinary income rates) for U.S. federal income and all applicable state and local Tax purposes or would have other material adverse Tax consequences to the TRA Party and/or its direct or indirect owners, then at the election of such TRA Party and to the extent specified by the TRA Party, this Agreement (i) shall cease to have further effect with respect to such TRA Party, (ii) shall not apply to an Exchange by the TRA Party occurring after a date specified by it, or (iii) shall otherwise be amended in a manner determined by the TRA Party to waive any benefits to which such TRA Party would otherwise be entitled under this Agreement, provided that such amendment shall not result in an increase in or acceleration of payments under this Agreement at any time as compared to the amounts and times of payments that would have been due in the absence of such amendment or increase the Corporation’s administrative burden in complying with this Agreement.

Section 7.4.    Governing Law.

D-22

Section 7.6.    Assignments; Amendments; Successors; No Waiver.

(a)    Assignment. No TRA Party is permitted to assign, sell, transfer, pledge, delegate, or otherwise dispose of any interest, right or obligation under this Agreement without the prior written approval of the Board (not to be unreasonably withheld, conditioned or delayed); provided, that to the extent Company Units are transferred in accordance with the terms of the Company LLC Agreement, the transferring TRA Party shall assign to the transferee of such Company Units the transferring TRA Party’s rights under this Agreement as long as such transferee has executed and delivered or, in connection with such transfer, executes and delivers, a Joinder agreeing to become a “TRA Party” for all purposes of this Agreement.

(b)    Amendments. No provision of this Agreement may be amended unless such amendment is approved in writing by each of the Corporation and by TRA Parties who would be entitled to receive more than fifty percent (50%) of the aggregate amount of the Early Termination Payments payable to all TRA Parties hereunder if the Corporation had exercised its right of Early Termination on the date of the most recent Exchange prior to such amendment (excluding, for purposes of this sentence, all payments made to any TRA Party pursuant to this Agreement since the date of such most recent Exchange); provided, however, that no such amendment shall be effective if such amendment would have a disproportionate effect on the payments certain TRA Parties will or may receive under this Agreement unless all such disproportionately affected TRA Parties consent in writing to such amendment; provided, further, that amendment of the definition of Change of Control or any approval rights granted to the Independent Directors will also require the written approval of a majority of the Independent Directors.

(c)    Successors. Except as provided in Section 7.6(a), all of the terms and provisions of this Agreement shall be binding upon, and shall inure to the benefit of and be enforceable by, the parties hereto and their respective successors, permitted assigns, heirs, executors, administrators and legal representatives. The Corporation shall require and cause any direct or indirect successor (whether by purchase, merger, consolidation or otherwise) to all or substantially all of the business or assets of the Corporation, by written agreement, expressly to assume and agree to perform this Agreement in the same manner and to the same extent that the Corporation would be required to perform if no such succession had taken place.

(d)    Waiver. Neither the failure nor delay on the part of any party hereto to exercise any right, remedy, power or privilege under this Agreement shall operate as a waiver thereof, nor shall any single or partial exercise of any right, remedy power or privilege preclude any other or further exercise of the same or of any other right, remedy, power or privilege, nor shall any waiver of any right, remedy, power or privilege with respect to any occurrence be construed as a waiver of such right, remedy, power or privilege with respect to any other occurrence. No party shall be deemed to have waived any claim arising out of this Agreement, or any right, remedy, power or privilege under this Agreement, unless the waiver of such claim, right, remedy, power or privilege is expressly set forth in a written instrument duly executed and delivered on behalf of such party; and any such waiver shall not be applicable or have any effect except in the specific instance in which it is given.

Section 7.7.    Titles and Subtitles. The titles of the sections and subsections of this Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

Section 7.8.    Resolution of Disputes.

(a)    Any and all disputes which cannot be settled amicably after good faith negotiations, including any ancillary claims of any party, arising out of, relating to or in connection with the validity, negotiation, execution, interpretation, performance or non-performance of this Agreement (including the validity, scope and enforceability of this arbitration provision) shall be finally settled by arbitration conducted by a single arbitrator in the state of Delaware in accordance with the then-existing Rules of Arbitration of the International Chamber of

Commerce. If the parties to the dispute fail to agree on the selection of an arbitrator within ten (10) calendar days

D-23

of the receipt of the request for arbitration, the International Chamber of Commerce shall make the appointment. The arbitrator shall be a lawyer and shall conduct the proceedings in the English language. Performance under this Agreement shall continue if reasonably possible during any arbitration proceedings.

(b)    Notwithstanding the provisions of Section 7.8(a), the Corporation and the TRA Party Representative may bring an action or special proceeding in any court of competent jurisdiction for the purpose of compelling another party to arbitrate, seeking temporary or preliminary relief in aid of an arbitration hereunder, and/or enforcing an arbitration award and, for the purposes of this Section 7.8(b), each TRA Party (i) expressly consents to the application of Section 7.8(b) to any such action or proceeding, (ii) agrees that proof shall not be required that monetary damages for breach of the provisions of this Agreement would be difficult to calculate and that remedies at law would be inadequate, and (iii) irrevocably appoints the Corporation as each TRA Party’s agent for service of process in connection with any such action or proceeding and agrees that service of process upon such agent, who shall promptly advise such TRA Party of any such service of process, shall be deemed in every respect effective service of process upon such TRA Party in any such action or proceeding.

(c)    (i) EACH TRA PARTY HEREBY IRREVOCABLY SUBMITS TO THE JURISDICTION OF COURTS LOCATED IN THE STATE OF DELAWARE FOR THE PURPOSE OF ANY JUDICIAL PROCEEDING BROUGHT IN ACCORDANCE WITH THE PROVISIONS OF SECTION 7.8(B), OR ANY JUDICIAL PROCEEDING ANCILLARY TO AN ARBITRATION OR CONTEMPLATED ARBITRATION ARISING OUT OF OR RELATING TO OR CONCERNING THIS AGREEMENT. Such ancillary judicial proceedings include any suit, action or proceeding to compel arbitration, to obtain temporary or preliminary judicial relief in aid of arbitration, or to confirm an arbitration award. The parties acknowledge that the forum designated by this Section 7.8(c) has a reasonable relation to this Agreement, and to the parties’ relationship with one another.

(ii)    The parties hereby waive, to the fullest extent permitted by applicable law, any objection which they now or hereafter may have to personal jurisdiction or to the laying of venue of any such ancillary suit, action or proceeding brought in any court referred to in Section 7.8(c)(i) of this Section 7.8 and such parties agree not to plead or claim the same.

Section 7.9.    Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER OR RELATE TO THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE EACH PARTY HERETO HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY ACTION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE BREACH OR VALIDITY OF THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. EACH PARTY HERETO CERTIFIES AND ACKNOWLEDGES THAT (i) NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH OTHER PARTY WOULD NOT, IN THE EVENT OF ACTION, SEEK TO ENFORCE THE FOREGOING WAIVER, (ii) EACH SUCH PARTY UNDERSTANDS AND HAS CONSIDERED THE IMPLICATIONS OF THIS WAIVER, (iii) EACH SUCH PARTY MAKES THIS WAIVER VOLUNTARILY, AND (iv) EACH SUCH PARTY HAS BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION 7.9.

Section 7.10.    Confidentiality. Each TRA Party and its assignees acknowledges and agrees that the information of the Corporation and its Affiliates provided pursuant to this Agreement is confidential and, except in the course of performing any duties as necessary for the Corporation and its Affiliates, as required by law or legal process or to enforce the terms of this Agreement, such Person shall keep and retain in the strictest confidence and not disclose to any Person any confidential matters of the Corporation and its Affiliates and successors acquired pursuant to this Agreement. This Section 7.10 shall not apply to (i) any information that has

D-24

been made publicly available by the Corporation, becomes public knowledge (except as a result of an act of any TRA Party in violation of this Agreement) or is generally known to the business community, (ii) the disclosure of information to the extent necessary for a TRA Party to prosecute or defend claims arising under or relating to this Agreement, (iii) the disclosure of information to the extent necessary for a TRA Party to prepare and file its Tax Returns, to respond to any inquiries regarding the same from any Taxing Authority or to prosecute or defend any action, proceeding or audit by any Taxing Authority with respect to such Tax Returns, and (iv) the disclosure to any potential assignee or transferee of information in connection with an assignment, sale, pledge, alienation or transfer of any interest in this Agreement pursuant to Section 7.6(a) so long as such potential assignee or transferee agrees to be subject to the provisions of this Section 7.10. Notwithstanding anything to the contrary in this Agreement, to the extent required by applicable law or to the extent reasonably necessary for a TRA Party to comply with any applicable reportable transaction requirements under applicable law, each TRA Party (and each employee, representative or other agent of the TRA Party, as applicable) may disclose the Tax treatment and Tax structure of the Corporation, the Company and their Subsidiaries, and any of their transactions, and all materials of any kind (including opinions or other Tax analyses) that are provided to the TRA Party relating to such Tax treatment and Tax structure.

Section 7.11.    Interest Rate Limitation. Notwithstanding anything to the contrary contained herein, the interest paid or agreed to be paid hereunder with respect to amounts due to any TRA Party hereunder shall not exceed the maximum rate of non-usurious interest permitted by applicable law (the “Maximum Rate”). If any TRA Party shall receive interest in an amount that exceeds the Maximum Rate, the excess interest shall be applied to the Tax Benefit Payment, Advance Payment or Early Termination Payment, as applicable (but in each case exclusive of any component thereof comprising interest) or, if it exceeds such unpaid non-interest amount, refunded to the Corporation. In determining whether the interest contracted for, charged, or received by any TRA Party exceeds the Maximum Rate, such TRA Party may, to the extent permitted by applicable law, (a) characterize any payment that is not principal as an expense, fee, or premium rather than interest, (b) exclude voluntary prepayments and the effects thereof and (c) amortize, prorate, allocate, and spread in equal or unequal parts the total amount of interest throughout the contemplated term of the payment obligations owed by the Corporation to such TRA Party hereunder. Notwithstanding the foregoing, it is the intention of the parties hereto to conform strictly to any applicable usury laws.

Section 7.12.    Independent Nature of Rights and Obligations.

(a)    The rights and obligations of the each TRA Party hereunder are several and not joint with the rights and obligations of any other Person. A TRA Party shall not be responsible in any way for the performance of the obligations of any other Person hereunder, nor shall a TRA Party have the right to enforce the rights or obligations of any other Person hereunder (other than the Corporation). Nothing contained herein or in any other agreement or document delivered at any closing, and no action taken by any TRA Party pursuant hereto or thereto, shall be deemed to constitute the TRA Parties acting as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the TRA Parties are in any way acting in concert or as a group with respect to such rights or obligations or the transactions contemplated hereby, and the Corporation acknowledges that the TRA Parties are not acting in concert or as a group and will not assert any such claim with respect to such rights or obligations or the transactions contemplated hereby.

(b)    Except as otherwise explicitly provided in this Agreement, the actions of a TRA Party pursuant to and in accordance with this Agreement shall be binding only with respect to such TRA Party and not with respect to the any other TRA Party. To the fullest extent permitted by law, no TRA Party shall owe any duties (fiduciary or otherwise) to any other TRA Party or any other Person in determining to take or refrain from taking any action or decision under or in connection with this Agreement.

2.2    Election of Directors.

(a)    From the Effective Date, CORE Designator shall have the right, but not the obligation, to nominate to the Board a number of designees (such persons, the “CORE Nominees”) equal to at least: (i) a majority of the Total Number of Directors (as defined below), so long as the CORE Investors Beneficially Own shares of Common Stock representing at least 50% of the Original Amount (as defined below), (ii) 35% of the Total Number of Directors, in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 20% but less than 35% of the Original Amount, (iii) 20% of the Total Number of Directors, in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 10% but less than 20% of the Original Amount and (iv) 1 (one) Director (as defined below), in the event that the CORE Investors Beneficially Own shares of Common Stock representing at least 5% of the Original Amount. For purposes of calculating the number of directors that CORE Designator is entitled to designate pursuant to the immediately preceding sentence, any fractional amounts shall automatically be rounded up to the nearest whole number (e.g., 11/4 Directors shall equate to 2 Directors) and any such calculations shall be made after taking into account any increase in the Total Number of Directors.

(b)    In the event that CORE Designator has nominated less than the total number of designees that CORE Designator is entitled to nominate pursuant to Section 2.2(a), CORE Designator shall have the right, at any time, to nominate such additional designees to which it is entitled, in which case, the Company and the Directors shall take all necessary corporation action, to the fullest extent permitted by applicable law (including with respect to fiduciary duties under Delaware law), to (x) enable CORE Designator to nominate and effect the election or appointment of such additional individuals, whether by increasing the size of the Board, or otherwise and (y) to designate such additional individuals nominated by CORE Designator to fill such newly created vacancies or to fill any other existing vacancies.

(c)    In addition to the nomination rights set forth in Section 2.2(a) above, from the Effective Date, for so long as the CORE Investors Beneficially Own shares of Common Stock representing at least 5% of the

E-7

Original Amount, CORE Designator shall have the right, but not the obligation, to designate a person (a “Non-Voting Observer”) to attend meetings of the Board (including any meetings of any committees thereof) in a non-voting observer capacity. Any such Non-Voting Observer shall be permitted to attend all meetings of the Board. CORE Designator shall have the right to remove and replace its Non-Voting Observer at any time and from time to time. The Company shall furnish to any Non-Voting Observer (i) notices of Board meetings no later than, and using the same form of communication as, notice of Board meetings are furnished to Directors and (ii) copies of any materials prepared for meetings of the Board that are furnished to the Directors no later than the time such materials are furnished to the Directors; provided, that (x) such Non-Voting Observer shall be required to execute or otherwise become subject to any codes of conduct or confidentiality agreements of the Company generally applicable to directors of the Company or as the Company reasonably requests and (y) the Company reserves the right to withhold any information and to exclude such Non-Voting Observer from any meeting or portion thereof to the extent access to such materials or attendance at such meeting would be reasonably likely to adversely affect the attorney-client privilege between the Company and its counsel or result in disclosure of trade secrets or a conflict of interest; provided, further, that failure to deliver notice, or materials, to such Non-Voting Observer in connection with such Non-Voting Observer’s right to attend and/or review materials with respect to, any meeting of the Board shall not, by itself, impair the validity of any action taken by such Board at such meeting.

(d)    The Company shall pay all reasonable out-of-pocket expenses incurred by the CORE Nominees and the Non-Voting Observer in connection with the performance of his or her duties as a Director or a Non-Voting Observer and in connection with his or her attendance at any meeting of the Board. In addition, as promptly as practicable following the request by any CORE Nominee who is serving as a Director, the Company shall enter into an indemnification agreement with such CORE Nominee in the form entered into with the other members of the Board.

(e)    No reduction in the number of shares of Common Stock that the CORE Investors Beneficially Own shall shorten the term of any incumbent director who is serving as a CORE Nominee.

(f)    In the event that any CORE Nominee shall cease to serve for any reason, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate such person’s successor in accordance with this Agreement and the Board shall promptly fill the vacancy with such successor nominee; it being understood that any such designee shall serve the remainder of the term of the director whom such designee replaces.

(g)    If a CORE Nominee is not appointed or elected to the Board because of such person’s death, disability, disqualification, withdrawal as a nominee or for other reason is unavailable or unable to serve on the Board, CORE Designator shall be entitled, for so long as CORE Designator retains the right to nominate a CORE Nominee to fill the applicable vacant seat, to designate promptly another nominee and the director position for which the original CORE Nominee was nominated shall not be filled pending such designation.

(h)    So long as CORE Designator has the right to nominate CORE Nominees under Section 2.2(a) or any such CORE Nominee is serving on the Board, the Company shall use its reasonable best efforts to maintain in effect at all times directors and officers indemnity insurance coverage in an amount determined by the Board to be reasonable and customary, and the Company Charter and Amended and Restated Bylaws (each as may be further amended, supplemented or waived in accordance with its terms) shall at all times provide for indemnification, exculpation and advancement of expenses to the fullest extent permitted under applicable law. Upon the removal or resignation of any CORE Nominee as a Director for any reason, the Company shall use commercially reasonable efforts to take all actions reasonably necessary to extend such director’s official liability insurance coverage for a period of not less than six (6) years from any such event in respect or any act or omission occurring at or prior to such event.

(i)    If the size of the Board is expanded, CORE Designator shall be entitled to nominate a number of CORE Nominees to fill the newly created vacancies such that the total number of CORE Nominees serving on

E-8

the Board following such expansion will be equal to that number of CORE Nominees that CORE Designator would be entitled to nominate in accordance with Section 2.2(a) if such expansion occurred immediately prior to any meeting of the stockholders of the Company called with respect to the election of members of the Board, and the Board shall appoint such CORE Nominees to the Board.

(j)    During such time as the Company is required by applicable law or the New York Stock Exchange or such other principal United States securities exchange on which the Class A Common Stock is listed, quoted, or admitted to trading (the “Exchange”) listing standards to have a majority of the Board comprised of “independent directors” (subject in each case to any applicable phase-in periods), CORE Nominees shall include a number of persons that qualify as “independent directors” under applicable law and the Exchange listing standards such that, together with any other “independent directors” then serving on the Board that are not CORE Nominees, the Board is comprised of a majority of “independent directors.”

(k)    At any time that CORE Designator shall have any nomination rights under Section 2.2, except as required by Law or the rules and regulations of the Exchange, the Company shall not take any action, including making or recommending any amendment to the Company Charter or the Company’s Amended and Restated Bylaws that could reasonably be expected to adversely affect CORE Designator’s rights, respectively, under this Agreement, in each case without the prior written consent of CORE Designator.

(l)    Any CORE Nominee will be subject to the Company’s customary due diligence process, including its review of a completed questionnaire and a background check. Based on the foregoing, the Company may object to any CORE Nominee if (a) it does so in good faith and (b) such objection is based upon any of the following: (i) such CORE Nominee was convicted in a criminal proceeding or is a named subject of a pending criminal proceeding (excluding traffic violations and other minor offenses); (ii) such CORE Nominee was the subject of any order, judgment, or decree not subsequently reversed, suspended or vacated of any court of competent jurisdiction, permanently or temporarily enjoining such proposed director from, or otherwise limiting, the following activities: (A) engaging in any type of business practice; or (B) engaging in any activity in connection with the purchase or sale of any security or in connection with any violation of federal or state securities laws; (iii) such CORE Nominee was the subject of any order, judgment or decree, not subsequently reversed, suspended or vacated, of any federal or state authority barring, suspending or otherwise limiting for more than sixty (60) days the right of such person to engage in any activity described in clause (ii)(B), or to be associated with persons engaged in such activity; (iv) such CORE Nominee was found by a court of competent jurisdiction in a civil action or by the Commission to have violated any federal or state securities law, and the judgment in such civil action or finding by the Commission has not been subsequently reversed, suspended or vacated; (v) such CORE Nominee was the subject of, or a party to any federal or state judicial or administrative order, judgment, decree or finding, not subsequently reversed, suspended or vacated, relating to a violation of any federal or state securities laws or regulations; or (vi) any other reason(s) that apply by reason of applicable Law, the rules and regulations of the Exchange or Company policy. In the event the Board reasonably finds the CORE Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (vi) and reasonably objects to the identified director, the CORE Designator shall be entitled to propose a different CORE Nominee to the Board within thirty (30) calendar days of the Company’s notice to the CORE Designator of its objection to the CORE Nominee and such replacement CORE Nominee shall be subject to the review process outlined above.

2.3    Company Obligations. The Company agrees to use its reasonable best efforts to ensure that prior to the date that the CORE Investors cease to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, (i) each CORE Nominee is included in the Board’s slate of nominees to the stockholders (the “Board Slate”) for each election of directors; and (ii) each CORE Nominee is included in the proxy statement prepared by management of the Company in connection with soliciting proxies for every meeting of the stockholders of the Company called with respect to the election of members of the Board (each, a “Director Election Proxy Statement”), and at every adjournment or postponement thereof, and on every action or approval by written consent of the stockholders of the Company or the Board with respect to the election of members of the Board. CORE Designator will promptly provide reporting to the

E-9

Company after CORE Designator ceases to Beneficially Own shares of Common Stock representing at least 5% of the total voting power of the then outstanding Common Stock, such that Company is informed of when this obligation terminates. The calculation of the number of CORE Nominees that CORE Designator is entitled to nominate to the Board Slate for any election of directors shall be based on the percentage of the total voting power of the then outstanding Common Stock then Beneficially Owned by CORE (“CORE Voting Control”), as applicable, immediately prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission). Unless CORE Designator notifies the Company otherwise prior to the mailing to stockholders of the Director Election Proxy Statement relating to an election of directors, the CORE Nominees for such election shall be presumed to be the same CORE Nominees currently serving on the Board, and no further action shall be required of CORE Designator for the Board to include such CORE Nominees on the Board’s Slate; provided, that, in the event CORE Designator is no longer entitled to nominate the full number of CORE Nominees then serving on the Board, CORE Designator shall provide advance written notice to the Company, of which currently serving CORE Nominee(s) shall be excluded from the Board Slate, and of any other changes to the list of CORE Nominees. If CORE Designator fails to provide such notice prior to the mailing to shareholders of the Director Election Proxy Statement relating to such election (or, if earlier, the filing of the definitive Director Election Proxy Statement with the U.S. Securities and Exchange Commission), a majority of the independent directors then serving on the Board shall determine which of the CORE Nominees of CORE Designator then serving on the Board will be included in the Board Slate.

2.4    Compensation. Except to the extent any CORE Designator may otherwise notify the Company with respect to such CORE Designator’s CORE Nominees, each CORE Nominee shall be entitled to compensation consistent with the Director compensation received by other Directors, including any fees and equity awards.

2.5    Other Rights of CORE Nominees. Except as provided in Section 2.3, each CORE Nominee serving on the Board shall be entitled to the same rights and privileges applicable to all other members of the Board generally or to which all such members of the Board are entitled. In furtherance of the foregoing, the Company shall, to the maximum extent permitted by applicable Law, indemnify, exculpate, and reimburse fees and expenses of the CORE Nominees (including by entering into an indemnification agreement in a form substantially similar to the Company’s form director indemnification agreement) and provide the CORE Nominees with director and officer insurance to the same extent it indemnifies, exculpates, reimburses and provides insurance for the other members of the Board pursuant to the Company Charter or Amended and Restated Bylaws of the Company, applicable Law or otherwise.

2.6    Director Independence. Notwithstanding anything to the contrary herein, the parties hereto shall ensure the composition of the Board will continue to meet all requirements for a company listed on the New York Stock Exchange (or such other stock exchange on which the Class A Common Stock may be listed from time to time), including with respect to director independence.

The Company shall file within 30 days of the Closing Date, and use commercially reasonable efforts to cause to be declared effective as soon as practicable thereafter, a Registration Statement for a Shelf Registration on Form S-1 (the “Form S-1 Shelf”) or, if the Company is eligible to use a Registration Statement on Form S-3, a Shelf Registration on Form S¬3 (the “Form S-3 Shelf”), in each case, covering the resale of all the Registrable Securities (determined as of two business days prior to such filing) on a delayed or continuous basis. Such Shelf shall provide for the resale of the Registrable Securities included therein pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. The Company shall maintain a Shelf in accordance with the terms hereof, and shall prepare and file with the SEC such amendments, including post-effective amendments, and supplements as may be necessary to keep a Shelf continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. In the event the Company files a Form S-1 Shelf, the Company shall use its commercially reasonable efforts to convert the Form S-1 Shelf (and any Subsequent Shelf Registration) to a Form S-3 Shelf as soon as practicable after the Company is eligible to use Form S-3 and, in any event, within 10 days following such date.

2.1.2    Subsequent Shelf Registration. If any Shelf ceases to be effective under the Securities Act for any reason at any time while Registrable Securities are still outstanding, the Company shall, subject to Section 3.4, use its commercially reasonable efforts to as promptly as is reasonably practicable cause such Shelf to again become effective under the Securities Act (including obtaining the prompt withdrawal of any order suspending the effectiveness of such Shelf), and shall use its commercially reasonable efforts to as promptly as is reasonably practicable amend such Shelf in a manner reasonably expected to result in the withdrawal of any order suspending the effectiveness of such Shelf or file an additional registration statement as a Shelf Registration (a “Subsequent Shelf Registration”) registering the resale of all Registrable Securities (determined as of two business days prior to such filing), and pursuant to any method or combination of methods legally available to, and requested by, any Investor named therein. If a Subsequent Shelf Registration is filed, the Company shall use its commercially reasonable efforts to (i) cause such Subsequent Shelf Registration to become effective under the Securities Act as promptly as is reasonably practicable after the filing thereof (it being agreed that the Subsequent Shelf Registration shall be an automatic shelf registration statement (as defined in Rule 405 promulgated under the Securities Act) if the Company is a well-known seasoned issuer (as defined in Rule 405 promulgated under the Securities Act) at the most recent applicable eligibility determination date) and (ii) keep such Subsequent Shelf Registration continuously effective, available for use and in compliance with the provisions of the Securities Act until such time as there are no longer any Registrable Securities. Any such Subsequent Shelf Registration shall be on Form S-3 to the extent that the Company is eligible to use such form. Otherwise, such Subsequent Shelf Registration shall be on another appropriate form.

2.1.3    Additional Registerable Securities. In the event that any Investor holds Registrable Securities that are not registered for resale on a delayed or continuous basis, the Company, upon request of a CORE Investor or any Sponsor Investor, shall promptly use its commercially reasonable efforts to cause the resale of such Registrable Securities to be covered by either, at the Company’s option, the Shelf (including by means of a post-effective amendment) or a Subsequent Shelf Registration and cause the same to become effective as soon as practicable after such filing and such Shelf or Subsequent Shelf Registration shall be subject to the terms hereof.

2.1.4    Requests for Underwritten Shelf Takedowns. At any time and from time to time when an effective Shelf is on file with the Commission, any CORE Investor or any Sponsor Investor (any of such Investors being, in such case, a “Demanding Investor”) may request to sell all or any portion of its Registrable Securities in an Underwritten Offering or other coordinated offering that is registered pursuant to the Shelf (each, an “Underwritten Shelf Takedown”); provided that the Company shall only be obligated to effect an Underwritten Shelf Takedown if such offering shall include Registrable Securities proposed to be sold by the

F-6

Demanding Investor with a total offering price reasonably expected to exceed, in the aggregate, $50 million (the “Minimum Takedown Threshold”). All requests for Underwritten Shelf Takedowns shall be made by giving written notice to the Company, which shall specify the approximate number of Registrable Securities proposed to be sold in the Underwritten Shelf Takedown. The Demanding Investor initiating the request shall have the right to select the Underwriters for such offering (which shall consist of one or more reputable nationally recognized investment banks), subject to the Company’s prior approval (which shall not be unreasonably withheld, conditioned or delayed). Notwithstanding anything to the contrary in this Section 2.1.4 and this Agreement, there shall be no limit to the number of Underwritten Shelf Takedowns that may be requested by any Demanding Investor. Notwithstanding anything to the contrary in this Agreement, the Company may effect any Underwritten Offering pursuant to any then effective Registration Statement, including a Form S-3, that is then available for such offering.

2.1.5    Reduction of Underwritten Offering. If the managing Underwriter or Underwriters in an Underwritten Shelf Takedown, in good faith, advises the Company, the Demanding Investors and the Investors requesting piggy back rights pursuant to this Agreement with respect to such Underwritten Shelf Takedown (the “Requesting Investors”) (if any) in writing that the dollar amount or number of Registrable Securities that the Demanding Investors and the Requesting Investors (if any) desire to sell, taken together with all other shares of Common Stock or other equity securities that the Company desires to sell and all other shares of Common Stock or other equity securities, if any, that have been requested to be sold in such Underwritten Offering pursuant to separate written contractual piggy-back registration rights held by any other stockholders, exceeds the maximum dollar amount or maximum number of equity securities that can be sold in the Underwritten Offering without adversely affecting the proposed offering price, the timing, the distribution method, or the probability of success of such offering (such maximum dollar amount or maximum number of such securities, as applicable, the “Maximum Number of Securities”), then the Company shall include in such Underwritten Offering, before including any shares of Common Stock or other equity securities proposed to be sold by Company or by other holders of Common Stock or other equity securities the following: (i) first, the Registrable Securities of the Demanding Investors and the Requesting Investors (if any) (pro rata based on the respective number of Registrable Securities that each Demanding Investor and Requesting Investor (if any) has requested be included in such Underwritten Shelf Takedown and the aggregate number of Registrable Securities that the Demanding Investors and Requesting Investors have requested be included in such Underwritten Shelf Takedown) that can be sold without exceeding the Maximum Number of Securities, (ii) second, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i), the Common Stock or other equity securities that Company desires to sell, which can be sold without exceeding the Maximum Number of Securities and (iii) third, to the extent that the Maximum Number of Securities has not been reached under Section 2.1.5(i) and 2.1.5 (ii), the Common Stock or other equity securities of any other Investor or any other person that Company is obligated to include in such Underwritten Offering pursuant to separate written contractual arrangements with such persons and that can be sold without exceeding the Maximum Number of Securities. To facilitate the allocation of Registrable Securities in accordance with the above provisions, the Company or the Underwriters may round the number of shares allocated to any Investor to the nearest 100 shares. The Company shall not be required to include any Registrable Securities in such Underwritten Shelf Takedown unless the Investors accept the terms of the underwriting as agreed upon between the Company and its Underwriters.

2.1.6    Withdrawal. Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used for marketing such Underwritten Shelf Takedown, a majority-in-interest of the Demanding Investors initiating an Underwritten Shelf Takedown shall have the right to withdraw from such Underwritten Shelf Takedown for any or no reason whatsoever upon written notification (a “Withdrawal Notice”) to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Shelf Takedown; provided that any Core Investor or a Sponsor Investor may elect to have the Company continue an Underwritten Shelf Takedown if the Minimum Takedown Threshold would still be satisfied by the Registrable Securities proposed to be sold in the Underwritten Shelf Takedown by such Investors or any of their respective Permitted Transferees, as applicable. If withdrawn, a demand for an Underwritten Shelf Takedown shall not constitute a demand for an Underwritten Shelf Takedown for purposes of Section 2.1.4. Following the receipt of any Withdrawal Notice, the Company shall promptly forward such Withdrawal Notice to any other Investors that had

F-7

elected to participate in such Shelf Takedown. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a Shelf Takedown prior to its withdrawal under this Section 2.1.6.

2.2    Piggyback Registration.

2.2.1    Piggyback Rights. Subject to Section 2.4.3, if the Company or any Investor proposes to conduct a registered offering of, or if the Company proposes to file a Registration Statement under the Securities Act with respect to the Registration of, equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into equity securities, for its own account or for the account of stockholders of the Company (or by the Company and by the stockholders of the Company including, without limitation, an Underwritten Shelf Takedown pursuant to Section 2.1 hereof), other than a Registration Statement (or any registered offering with respect thereto) (i) filed in connection with any employee stock option or other benefit plan, (ii) pursuant to a Registration Statement on Form S-4 (or similar form that relates to a transaction subject to Rule 145 under the Securities Act or any successor rule thereto), (iii) for an offering of debt that is convertible into equity securities of the Company or, (iv) for a dividend reinvestment plan or (v) for a rights offering, then the Company shall give written notice of such proposed offering to all of the Investors of Registrable Securities as soon as practicable but not less than ten (10) days before the anticipated filing date of such Registration Statement or, in the case of an Underwritten Offering pursuant to a Shelf Registration, the applicable “red herring” prospectus or prospectus supplement used for marketing such offering, which notice shall (A) describe the amount and type of securities to be included in such offering, the intended method(s) of distribution, and the name of the proposed managing Underwriter or Underwriters, if any, in such offering, and (B) offer to all of the Investors of Registrable Securities the opportunity to include in such registered offering such number of Registrable Securities as such Investors may request in writing within five (5) days after receipt of such written notice (such registered offering, a “Piggyback Registration”). Subject to Section 2.2.2, the Company shall, in good faith, cause such Registrable Securities to be included in such Piggyback Registration and, if applicable, shall use its commercially reasonable efforts to cause the managing Underwriter or Underwriters of such Piggyback Registration to permit the Registrable Securities requested by the Investors pursuant to this Section 2.2.1 to be included therein on the same terms and conditions as any similar securities of the Company included in such registered offering and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. The inclusion of any Investor’s Registrable Securities in a Piggyback Registration shall be subject to such Investor’s agreement to enter into an underwriting agreement in customary form with the Underwriter(s) selected for such Underwritten Offering.

2.2.2    Reduction of Piggyback Registration. If the managing Underwriter or Underwriters in an Underwritten Offering that is to be a Piggyback Registration, in good faith, advises the Company and the Investors of Registrable Securities participating in the Piggyback Registration in writing that the dollar amount or number of shares of Common Stock or other equity securities that the Company desires to sell, taken together with (i) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been demanded pursuant to separate written contractual arrangements with persons or entities other than the Investors of Registrable Securities hereunder, (ii) the Registrable Securities as to which registration has been requested pursuant to Section 2.2 hereof, and (iii) the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to separate written contractual piggy-back registration rights of other stockholders of the Company, exceeds the Maximum Number of Securities, then:

(a)    If the Registration or registered offering is undertaken for the Company’s account, the Company shall include in any such Registration or registered offering (A) first, the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Investors exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Investor has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Investors have requested to be included in such

F-8

Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; and (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities, if any, as to which Registration or a registered offering has been requested pursuant to written contractual piggy-back registration rights of other stockholders of the Company, which can be sold without exceeding the Maximum Number of Securities;

(b)    If the Registration or registered offering is pursuant to a request by persons or entities other than the Investors of Registrable Securities, then the Company shall include in any such Registration or registered offering (A) first, the shares of Common Stock or other equity securities, if any, of such requesting persons or entities, other than the Investors of Registrable Securities, which can be sold without exceeding the Maximum Number of Securities; (B) second, to the extent that the Maximum Number of Securities has not been reached under the foregoing clause (A), the Registrable Securities of Investors exercising their rights to register their Registrable Securities pursuant to Section 2.2.1, pro rata, based on the respective number of Registrable Securities that each Investor has requested be included in such Underwritten Offering and the aggregate number of Registrable Securities that the Investors have requested to be included in such Underwritten Offering, which can be sold without exceeding the Maximum Number of Securities; (C) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A) and (B), the shares of Common Stock or other equity securities that the Company desires to sell, which can be sold without exceeding the Maximum Number of Securities; and (D) fourth, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (A), (B) and (C), the shares of Common Stock or other equity securities for the account of other persons or entities that the Company is obligated to register pursuant to separate written contractual arrangements with such persons or entities, which can be sold without exceeding the Maximum Number of Securities; and

(c)    If the Registration or registered offering is pursuant to a request by Investor(s) of Registrable Securities pursuant to Section 2.1 hereof, then the Company shall include in any such Registration or registered offering securities pursuant to Section 2.1.5.

2.2.3    Piggyback Registration Withdrawal. Any Investor of Registrable Securities (other than a Demanding Holder, whose right to withdrawal from an Underwritten Shelf Takedown, and related obligations, shall be governed by Section 2.1.6) shall have the right to withdraw from a Piggyback Registration for any or no reason whatsoever upon written notification to the Company and the Underwriter or Underwriters (if any) of his, her or its intention to withdraw from such Piggyback Registration prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Piggyback Registration or, in the case of a Piggyback Registration pursuant to a Shelf Registration, the filing of the applicable “red herring” prospectus or prospectus supplement with respect to such Piggyback Registration used for marketing such transaction. Notwithstanding anything to the contrary in this Agreement (other than Section 2.1.6), the Company shall be responsible for the Registration Expenses incurred in connection with the Piggyback Registration prior to its withdrawal under this Section 2.2.3.

2.2.4    Unlimited Piggyback Registration Rights. For purposes of clarity, subject to Section 2.1.6, any Piggyback Registration effected pursuant to Section 2.2 hereof shall not be counted as a demand for an Underwritten Shelf Takedown under Section 2.1.4 hereof.

2.3    Market Stand-off. In connection with any Underwritten Offering of equity securities of the Company (other than a Block Trade), each Investor is given an opportunity to participate in the Underwritten Offering pursuant to the terms of this Agreement agrees that it shall not Transfer any shares of Common Stock or other equity securities of the Company (other than those included in such offering pursuant to this Agreement), without the prior written consent of the Company, during the 90-day period beginning on the date of pricing of such offering or such shorter period during which the Company agrees not to conduct an underwritten primary offering of Common Stock, except in the event the Underwriters managing the offering otherwise agree by written consent. Each Investor agrees to execute a customary lock-up agreement in favor of the Underwriters to such effect (in each case on substantially the same terms and conditions as all such Investors).

F-9

2.4    Block Trades.

2.4.1    Notwithstanding the foregoing, at any time and from time to time when an effective Shelf is on file with the Commission and effective, if a Demanding Investor wishes to engage in an underwritten or other coordinated registered offering not involving a “roadshow,” an offer commonly known as a “block trade” (a “Block Trade”), with a total offering price reasonably expected to exceed, in the aggregate, either (x) $50 million or (y) all remaining Registrable Securities held by the Demanding Investor, then notwithstanding the time periods provided for in Section 2.1.4, such Demanding Investor need only to notify the Company of the Block Trade at least five (5) business days prior to the day such offering is to commence and the Company shall as expeditiously as possible use its commercially reasonable efforts to facilitate such Block Trade; provided that the Demanding Investors representing a majority of the Registrable Securities wishing to engage in the Block Trade shall use reasonable best efforts to work with the Company and any Underwriters prior to making such request in order to facilitate preparation of the registration statement, prospectus and other offering documentation related to the Block Trade.

2.4.2    Prior to the filing of the applicable “red herring” prospectus or prospectus supplement used in connection with a Block Trade, a majority-in-interest of the Demanding Investors initiating such Block Trade shall have the right to submit a Withdrawal Notice to the Company and the Underwriter or Underwriters (if any) of their intention to withdraw from such Block Trade. Notwithstanding anything to the contrary in this Agreement, the Company shall be responsible for the Registration Expenses incurred in connection with a block trade prior to its withdrawal under this Section 2.4.2.

2.4.3    Notwithstanding anything to the contrary in this Agreement, Section 2.2 hereof shall not apply to a Block Trade initiated by a Demanding Investor pursuant to this Agreement.

2.4.4    The Demanding Investor initiating a Block Trade shall have the right to select the Underwriters for such Block Trade (which shall consist of one or more reputable, nationally recognized investment banks).

each preliminary Prospectus), and such other documents as the Underwriters and the Investors of Registrable Securities included in such Registration or the legal counsel for any such Investors may request in order to facilitate the disposition of the Registrable Securities owned by such Investors;

3.1.4    prior to any public offering of Registrable Securities (i) register or qualify the Registrable Securities covered by the Registration Statement under such securities or “blue sky” laws of such jurisdictions in the United States as the Investors of Registrable Securities included in such Registration Statement (in light of their intended plan of distribution) may request (or provide evidence satisfactory to such Investors that the Registrable Securities are exempt from such registration or qualification) and (ii) take such action necessary to cause such Registrable Securities covered by the Registration Statement to be registered with or approved by such other governmental authorities as may be necessary by virtue of the business and operations of the Company and do any and all other acts and things that may be necessary or advisable to enable the Investors of Registrable Securities included in such Registration Statement to consummate the disposition of such Registrable Securities in such jurisdictions; provided, however, that the Company shall not be required to qualify generally to do business in any jurisdiction where it would not otherwise be required to qualify or take any action to which it would be subject to general service of process or taxation in any such jurisdiction where it is not then otherwise so subject;

3.1.13    in the event of any Underwritten Offering or other coordinated offering that is registered pursuant to a Registration Statement, enter into and perform its obligations under an underwriting agreement, sales agreement or placement agreement, in usual and customary form, with the managing Underwriter, sales agent or placement agent of such offering;

3.1.14    make available to its security holders, as soon as reasonably practicable, an earnings statement covering the period of at least twelve (12) months beginning with the first day of the Company’s first full calendar quarter after the effective date of the Registration Statement which satisfies the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder (or any successor rule then in effect);

3.1.15    if the Registration involves the Registration of Registrable Securities involving gross proceeds in excess of $50 million with respect to an Underwritten Offering pursuant to Section 2.1.4, use its reasonable efforts to make available senior executives of the Company to participate in customary “road show” presentations that may be reasonably requested by the Underwriter in such Underwritten Offering; and

3.1.16    otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by the Investors, in connection with such Registration.

3.3    Requirements for Participation in Registration Statement Underwritten Offerings. Notwithstanding anything in this Agreement to the contrary, if any Investor does not provide the Company with its requested Investor Information, the Company may exclude such Investor’s Registrable Securities from the applicable Registration Statement or Prospectus if the Company determines, based on the advice of counsel, that such information is necessary to effect the registration and such Investor continues thereafter to withhold such information. No person may participate in any Underwritten Offering or other coordinated offering for equity securities of the Company pursuant to a Registration initiated by the Company hereunder unless such person (i) agrees to sell such person’s securities on the basis provided in any arrangements approved by the Company and (ii) completes and executes all customary questionnaires, powers of attorney, indemnities, lock-up agreements, underwriting or other agreements and other customary documents as may be reasonably required under the terms of such arrangements. The exclusion of an Investor’s Registrable Securities as a result of this Section 3.3 shall not affect the registration of the other Registrable Securities to be included in such Registration.

F-12

3.4    Suspension of Sales; Adverse Disclosure; Restrictions on Registration Rights.

3.4.1    Upon receipt of written notice from the Company that a Registration Statement or Prospectus contains a Misstatement, each of the Investors shall forthwith discontinue disposition of Registrable Securities until it has received copies of a supplemented or amended Prospectus correcting the Misstatement (it being understood that the Company hereby covenants to prepare and file such supplement or amendment as soon as practicable after the time of such notice), or until it is advised in writing by the Company that the use of the Prospectus may be resumed.

3.4.2    If the filing, initial effectiveness or continued use of a Registration Statement in respect of any Registration at any time would (a) require the Company to make an Adverse Disclosure, (b) require the inclusion in such Registration Statement of financial statements that are unavailable to the Company for reasons beyond the Company’s control, or (c) in the good faith judgment of the majority of the Board such Registration, be seriously detrimental to the Company and the majority of the Board concludes as a result that it is essential to defer such filing, initial effectiveness or continued use at such time, the Company may, upon giving prompt written notice of such action to the Investors, delay the filing or initial effectiveness of, or suspend use of, such Registration Statement for the shortest period of time determined in good faith by the Company to be necessary for such purpose. In the event the Company exercises its rights under this Section 3.4.2, the Investors agree to suspend, immediately upon their receipt of the notice referred to above, their use of the Prospectus relating to any Registration in connection with any sale or offer to sell Registrable Securities.

3.4.3    (a) During the period starting with the date sixty (60) days prior to the Company’s good faith estimate of the date of the filing of, and ending on a date one hundred and twenty (120) days after the effective date of, a Company-initiated Registration and provided that the Company continues to actively employ, in good faith, all reasonable efforts to maintain the effectiveness of the applicable Shelf Registration Statement, or (b) if, pursuant to Section 2.1.4, Investors have requested an Underwritten Shelf Takedown and the Company and such Investors are unable to obtain the commitment of underwriters to firmly underwrite such offering, the Company may, upon giving prompt written notice of such action to the Investors, delay any other registered offering pursuant to Section 2.1.4 or 2.4. Notwithstanding anything to the contrary contained in this Agreement and except for the obligations set forth in Section 2.1.1 and Section 2.2.2, no Registration shall be effected or permitted, no Registration Statement shall become effective, and no notice shall be refused to be delivered with respect to any Registrable Securities held by any Investor, until after the expiration of the Lock-Up Period applicable to the securities.

3.5    Reporting Obligations. As long as any Investor shall own Registrable Securities, the Company, at all times while it shall be a reporting company under the Exchange Act, covenants to file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of the Exchange Act and to promptly furnish the Investors with true and complete copies of all such filings; provided that any documents publicly filed or furnished with the Commission pursuant to the Electronic Data Gathering, Analysis and Retrieval System shall be deemed to have been furnished or delivered to the Investors pursuant to this Section 3.5. The Company further covenants that it shall take such further action as any Investor may reasonably request, all to the extent required from time to time to enable such Investor to sell shares of Common Stock held by such Investor without registration under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act (or any successor rule then in effect). Upon the request of any Investor, the Company shall deliver to such Investor a written certification of a duly authorized officer as to whether it has complied with such requirements.

4.1    Indemnification.

4.1.1    The Company agrees to indemnify, to the extent permitted by law, each Investor of Registrable Securities, its officers, directors and agents and each person who controls such Investor (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information or affidavit so furnished in writing to the Company by such Investor expressly for use therein.

4.1.2    In connection with any Registration Statement in which an Investor of Registrable Securities is participating, such Investor shall furnish to the Company in writing such information and affidavits as the Company reasonably requests for use in connection with any such Registration Statement or Prospectus (the “Investor Information”) and, to the extent permitted by law, shall indemnify the Company, its directors, officers and agents and each person who controls the Company (within the meaning of the Securities Act) against all losses, claims, damages, liabilities and out-of-pocket expenses (including without limitation reasonable outside attorneys’ fees) resulting from any untrue or alleged untrue statement of material fact contained in any Registration Statement, Prospectus or preliminary Prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing by such Investor expressly for use therein; provided, however, that the obligation to indemnify shall be several, not joint and several, among such Investors of Registrable Securities, and the liability of each such Investor of Registrable Securities shall be in proportion to and limited to the net proceeds received by such Investor from the sale of Registrable Securities pursuant to such Registration Statement. The Investors of Registrable Securities shall indemnify the Underwriters, their officers, directors and each person who controls such Underwriters (within the meaning of the Securities Act) to the same extent as provided in the foregoing with respect to indemnification of the Company.

4.1.3    Any person entitled to indemnification herein shall (i) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not materially prejudiced the indemnifying party) and (ii) unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist with respect to such claim, permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent (but such consent shall not be unreasonably withheld). An indemnifying party who is not entitled to, or elects not to, assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of any indemnified party a conflict of interest may exist between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

4.1.4    The indemnification provided for under this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director or controlling person of such indemnified party and shall survive the transfer of securities. The Company and each

F-14

Investor of Registrable Securities participating in an offering also agrees to make such provisions as are reasonably requested by any indemnified party for contribution to such party in the event the Company’s or such Investor’s indemnification is unavailable for any reason.

4.1.5    If the indemnification provided under Section 4.1 hereof from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and out-of-pocket expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and out-of-pocket expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action; provided, however, that the liability of any Investor under this Section 4.1.5 shall be limited to the amount of the net proceeds received by such Investor in such offering giving rise to such liability. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth in Sections 4.1.1, 4.1.2 and 4.1.3 above, any legal or other fees, charges or out-of-pocket expenses reasonably incurred by such party in connection with any investigation or proceeding. The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.1.5 were determined by pro rata allocation or by any other method of allocation, which does not take account of the equitable considerations referred to in this Section 4.1.5. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 4.1.5 from any person who was not guilty of such fraudulent misrepresentation.

ARTICLE I DEFINITIONS

Section 1.01. Definitions. Capitalized terms used herein without definition have the following meanings (such meanings being equally applicable to both the singular and plural form of the terms defined):

“Act” means, the Delaware Limited Liability Company Act, 6 Del. C. Section 18-101, et seq., as it may be amended or supplemented from time to time and any successor thereto.

The foregoing definition of Adjusted Capital Account Balance is intended to comply with the provisions of Treasury Regulations Section 1.704-1(b)(2)(ii)(d) and shall be interpreted consistently therewith.

“Affiliate” means, with respect to a specified Person, any other Person that directly, or indirectly through one or more intermediaries, Controls, is Controlled by, or is under common Control with, such specified Person.

“Assumed Tax Rate” means the highest effective marginal combined U.S. federal, state and local income tax rate (including, without limitation, the “Medicare” contribution tax imposed on certain investment income under Section 1411 of the Code) for a taxable year prescribed for an individual (or, if greater, a corporation) resident in the city of New York, New York (or such other resident for which the Managing Member determines to have a higher effective marginal combined U.S. federal, state and local income tax rate) at the time of such distribution, taking into account (a) the deductibility of state and local income taxes for U.S. federal income tax purposes (if applicable, and taking into account any limitations thereon, provided, that, for administrative convenience, it shall be assumed that no portion of any state or local taxes shall be deductible for so long as the limitation set forth in Section 164(b)(6)(B) of the Code as of the date hereof remains unchanged), and (b) the character (e.g., long-term or short-term capital gain or ordinary or exempt income) of the applicable income. For the avoidance of doubt, the Assumed Tax Rate shall be the same for all Members.

G-5

“Available Cash” means the amount of cash on hand, available borrowings, and other funds available for Tax Distributions (including cash on hand, available borrowings, and other funds available to be lent or distributed to the Company by any Subsidiary of the Company for such purpose), as reasonably determined by the Managing Member, taking into account all debts, liabilities and obligations of the Company then due as well as any reserves established in accordance with GAAP.

“Board of Directors” means the board of directors of Pubco at any time.

“Business Combination Agreement” means the Business Combination Agreement, dated as of July 15, 2021, by and among the Managing Member, the Company, the Fathom Blockers and the other parties thereto, as the same may be amended, restated, supplemented and/or otherwise modified from time to time.

“Business Day” means a day, other than a Saturday or Sunday or other day on which commercial banks in New York City are open for the general transaction of business.

“Capital Account” means the separate capital account maintained for each Member in accordance with Section 5.03 hereof.

“Capital Contribution” means, with respect to any Member, the aggregate amount of money contributed to the Company and the Carrying Value of any property (other than money), net of any liabilities assumed by the Company upon contribution or to which such property is subject, contributed to the Company pursuant to Article V.

“Carrying Value” means, with respect to any Company asset, the asset’s adjusted basis for U.S. federal income tax purposes, except that the initial carrying value of assets contributed to the Company shall be their respective gross fair market values on the date of contribution, and the Carrying Values of all Company assets shall be adjusted to equal their respective fair market values, in accordance with the rules set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(f), except as otherwise provided herein, as of: (a) the date of the acquisition of any additional limited liability company interest in the Company by any new or existing Member in exchange for more than a de minimis Capital Contribution; (b) the date of the distribution of more than a de minimis amount of Company assets to a Member; (c) the date a limited liability company interest in the Company is relinquished to the Company; (d) the vesting of any Earnout Unit upon the occurrence of an Earnout Vesting Event, in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s) or (e) any other date specified in the Treasury Regulations; provided, however, that adjustments pursuant to clauses (a) through (e) above shall be made only if such adjustments are deemed necessary or appropriate by the Managing Member in its reasonable discretion to reflect the relative economic interests of the Members. The Carrying Value of any Company asset distributed to any Member shall be adjusted immediately before such distribution to equal its fair market value. In the case of any asset that has a Carrying Value that differs from its adjusted tax basis, Carrying Value shall be adjusted by the amount of depreciation calculated for purposes of the definition of “Profits” and “Losses” rather than the amount of depreciation determined for U.S. federal income tax purposes, and depreciation shall be calculated by reference to Carrying Value rather than tax basis once Carrying Value differs from tax basis.

“Cash Exchange Notice” has the meaning set forth in Section 8.04(b)(ii).

“Certificate” means the Certificate of Formation of the Company as filed in the office of the Secretary of State of Delaware on April 16, 2021, as amended.

“Change of Control” means the occurrence of any transaction or series of related transactions in which: (a) any Person or any group of Persons (other than Pubco or any of its Subsidiaries) that would constitute a “group” for purposes of Section 13(d) of the Exchange Act becomes the beneficial owner, directly or indirectly, of securities of Pubco or the Company representing more than 50% of the combined voting power of Pubco’s or

G-6

the Company’s, as applicable, then outstanding voting securities, (b) there is consummated a merger or consolidation of Pubco or the Company with any other Person, and, immediately after the consummation of such merger or consolidation, the outstanding voting securities of Pubco or the Company, as applicable, immediately prior to such merger or consolidation do not continue to represent or are not converted into more than 50% of the combined voting power of the then outstanding voting securities of the Person resulting from such merger or consolidation or, if Pubco or the Company, as applicable (or its successor) is a Subsidiary of such Person, the ultimate parent thereof, or (c) there is consummated an agreement or series of related agreements resulting in the sale or transfer, directly or indirectly, by Pubco of all or substantially all of Pubco’s and its Subsidiaries’ assets (including equity interests in the Company). Notwithstanding the foregoing, a “Change of Control” shall not be deemed to have occurred by virtue of the consummation of any transaction or series of related transactions (including by way of merger or consolidation) immediately following which the record holders of the shares of Pubco immediately prior to such transaction or series of related transactions continue to have substantially the same proportionate ownership in, and voting control over, and own substantially all of the shares of, an entity which owns, directly or indirectly, all or substantially all of the assets of Pubco immediately following such transaction or series of related transactions.

“Class” means the classes of Units into which the limited liability company interests in the Company may be classified or divided from time to time by the Managing Member in its sole discretion pursuant to the provisions of this Agreement. As of the date of this Agreement the only Class is the Class A Units (which includes the Earnout Units). For all purposes hereunder and under the Act, only such Classes expressly established under this Agreement, including by the Managing Member in accordance with this Agreement, shall be deemed to be a class of limited liability company interests in the Company.

The Officers of the Company shall have such titles and powers and perform such duties as shall be determined from time to time by the Managing Member and otherwise as shall customarily pertain to such offices. Any number of offices may be held by the same individual. In its sole discretion, the Managing Member may choose not to fill any office for any period as it may deem advisable. All Officers and other individuals providing services to or for the benefit of the Company shall be subject to the supervision and direction of the Managing Member and may be removed, with or without cause, from such office by the Managing Member and the authority, duties or responsibilities of any employee, agent or officer of the Company may be suspended by the Managing Member from time to time, in each case in the sole discretion of the Managing Member. The Managing Member shall not cease to be a Managing Member of the Company as a result of the delegation of any duties hereunder. No Officer of the Company, in his or her capacity as such, shall be considered a Managing Member of the Company by agreement, as a result of the performance of his or her duties hereunder or otherwise.

Section 3.05. Authority of Members. No Member (other than the Managing Member, in its capacity as such) shall participate in or have any control over the business of the Company, except as expressly provided herein. Except as expressly provided herein, the Units do not confer any rights upon the Members to participate in the affairs of the Company described in this Agreement. No Member (other than the Managing Member) shall have any right to vote on any matter involving the Company, including with respect to any merger, consolidation,

G-17

combination or conversion of the Company, or any other matter that a Member might otherwise have the ability to vote on or consent with respect to under the Act, at law, in equity or otherwise. The conduct, control and management of the Company shall be vested exclusively in the Managing Member, subject to the terms of this Agreement. In all matters relating to or arising out of the conduct of the operation of the Company, the decision of the Managing Member shall be the decision of the Company. Except as required or permitted by Law, or expressly provided herein, including in the ultimate sentence of this Section 3.05 or by separate agreement with the Company, no Member who is not also the Managing Member (and acting in such capacity) shall take any part in the management or control of the operation or business of the Company in its capacity as a Member, nor shall any Member who is not also the Managing Member (and acting in such capacity) have any right, authority or power to act for or on behalf of or bind the Company in his or its capacity as a Member in any respect or assume any obligation or responsibility of the Company or of any other Member. Notwithstanding the foregoing, the Company may from time to time appoint one or more Members as Officers or employ one or more Members as employees, and such Members, in their capacity as officers or employees of the Company (and not, for clarity, in their capacity as Members of the Company), may take part in the control and management of the business of the Company to the extent such authority and power to act for or on behalf of the Company has been delegated to them by the Managing Member.

Section 3.06. Fiduciary Duties.

(a) Notwithstanding any other provision to the contrary in this Agreement, except as set forth in Section 3.06(b), (i) the Managing Member shall, in its capacity as Managing Member, and not in any other capacity, have the same fiduciary duties to the Company and the Members as a member of the board of directors of a Delaware corporation; and (ii) each officer of the Company shall, in his or her capacity as such, and not in any other capacity, have the same fiduciary duties to the Company and Members as an officer of a Delaware corporation

(b) In connection with the performance of its duties as the Managing Member of the Company, the Managing Member (solely in its capacity as such) will owe to the other Members the same fiduciary duties as it would owe to the stockholders of a Delaware corporation if it were a member of the board of directors of such a corporation and the other Members were stockholders of such corporation. The Managing Member will use commercially reasonable and appropriate efforts and means, as determined in good faith by the Managing Member, to minimize any conflict of interest between the Members, on the one hand, and the stockholders of the Managing Member, on the other hand, and to effectuate any transaction that involves or affects any of the Company, the Managing Member, the Members and/or the stockholders of the Managing Member in a manner that does not (i) disadvantage the Members of their interests relative to the stockholders of the Managing Member; (ii) advantage the stockholders of the Managing Member relative to the Members; or (iii) treat the Members and the stockholders of the Managing Member differently.

ARTICLE IV

DISTRIBUTIONS

Section 4.01. Distributions

(a) The Managing Member, in its sole discretion, may authorize distributions by the Company to the Class A Members, which distributions shall be made pro rata in accordance with the Members’ respective Class A Units (other than Unvested Earnout Units) on the date the distribution is made.

(b) Notwithstanding anything in Section 4.01(a) of this Agreement to the contrary, no distribution shall be made in respect of any Unvested Earnout Units. However, upon the vesting of Unvested Earnout Units the holder of each applicable Earnout Unit shall be entitled to a cash payment from the Company in an amount equal to the distributions such Member would have received pursuant to Section 4.01(a) had such Unvested Earnout Unit

G-18

been vested beginning at the Fathom Effective Time and ending on the day prior to the date such Unvested Earnout Unit vests.

(c) Tax Distributions.

(i) With respect to each Fiscal Year or portion thereof ending after the Effective Date, the Company shall, to the extent permitted by applicable Law, make cash distributions (“Tax Distributions”) to each Member in an amount to ensure that each such Member receives a distribution at least equal to such Member’s Assumed Tax Liability, if any, with respect to the relevant taxable period to which the distribution relates. For the avoidance of doubt, such Tax Distributions shall be determined in accordance with Section 4.01(c)(ii). Tax Distributions pursuant to this Section 4.1(c)(i) shall be estimated by the Company on a quarterly basis and, to the extent feasible, shall be distributed to the Members (together with a statement showing the calculation of such Tax Distribution and an estimate of the Company’s net taxable income allocable to each Member for such period) on a quarterly basis five business days prior to April 15th, June 15th, September 15th and January 15th (of the succeeding year) (or such other dates for which individuals are required to make quarterly estimated tax payments for U.S. federal income tax purposes) (each, a “Quarterly Tax Distribution”); provided, that the foregoing shall not restrict the Company from making a Tax Distribution on any other date. Quarterly Tax Distributions shall take into account the estimated taxable income or loss of the Company for the Fiscal Year through the end of the relevant quarterly period. A final accounting for Tax Distributions shall be made for each Fiscal Year after the allocation of the Company’s actual net taxable income or loss has been determined and any shortfall in the amount of Tax Distributions a Member received for such Fiscal Year based on such final accounting shall promptly be distributed to such Member. For the avoidance of doubt, any excess Tax Distributions a Member receives with respect to any Fiscal Year shall reduce future Tax Distributions otherwise required to be made to such Member with respect to any subsequent Fiscal Year.

(ii) A Tax Distribution to a Member in respect of any Unit shall be charged against current or future distributions to which such Member would otherwise have been entitled under Section 4.01(a) or Section 9.03(c) in respect of such Unit; provided, however, that all Units shall participate in distributions made pursuant to this Section 4.01(c) on a pro rata basis. Notwithstanding the foregoing, (A) any distributions made pursuant to this Section 4.01(c) shall be made to the Members on a pro rata basis, (B) to the extent of Available Cash, the pro rata amount to be distributed to each Member shall be calculated based on the distribution to the Member that would have the highest Tax Distribution under this Section 4.01(c) on a per-Unit basis, calculated without regard to this sentence and (C) if there is insufficient Available Cash to make all of the distributions described in clause (B), the amount that would have been distributed to each Member pursuant to clause (B) shall be reduced on a pro rata basis and the Company shall make future Tax Distributions as soon as there is sufficient Available Cash to pay the remaining portion of the Tax Distributions to which such Members were otherwise entitled under clause (B).

(iii) In the event of any audit by a taxing authority that has been finally settled and as such, affects the calculation of any Member’s Assumed Tax Liability for any taxable year (other than an audit conducted pursuant to the Partnership Audit Provisions for which no election is made pursuant to Section 6226 thereof and the Treasury Regulations promulgated thereunder), or in the event the Company files an amended tax return, each Member’s Assumed Tax Liability with respect to such year shall be recalculated by giving effect to such event (for the avoidance of doubt, taking into account interest or penalties). Any shortfall in the amount of Tax Distributions the Members and former Members received for the relevant taxable years based on such recalculated Assumed Tax Liability promptly shall be distributed to such Members and the successors of such former Members, except, for the avoidance of doubt, to the extent Distributions were made to such Members and former Members pursuant to Section 4.01(a) and this Section 4.01(c) in the relevant taxable years sufficient to cover such shortfall.

(d) Notwithstanding anything to the contrary set forth herein, the Managing Member shall cause any distributions paid to any Subsidiary of the Managing Member who holds Units to distribute the full amount of

G-19

such distribution to the Managing Member, and the Managing Member shall take all actions necessary to cause such distributions.

Section 4.02. Distributions Upon Liquidation. Distributions made upon dissolution of the Company shall be made as provided in Section 9.03.

Section 4.03. Limitations on Distribution. Notwithstanding any provision to the contrary contained in this Agreement, the Managing Member shall not make a distribution to any Member if such distribution would violate Section 18-607 of the Act or other applicable Law or any applicable debt instrument.

ARTICLE V

CAPITAL CONTRIBUTIONS; CAPITAL ACCOUNTS;

TAX ALLOCATIONS; TAX MATTERS

Section 5.01. Initial Capital Contributions. The Members have made, on or prior to the date hereof, Capital Contributions and, in exchange, the Company has issued to the Members the number of Class A Units, including the number of Earnout Units (if applicable), as specified in the Schedule of Members (as of the Effective Date).

Section 5.02. No Additional Capital Contributions. Except as otherwise provided in this Article V, no Member shall be required to make additional Capital Contributions to the Company without the consent of such Member or permitted to make additional capital contributions to the Company without the consent of the Managing Member, which may be granted or withheld in its sole discretion.

Section 5.03. Capital Accounts. A separate Capital Account shall be established and maintained for each Member in accordance with the provisions of Treasury Regulations Section 1.704-1(b)(2)(iv). The Capital Account of each Member shall be credited with such Member’s Capital Contributions, if any, all Profits allocated to such Member pursuant to Section 5.04 and any items of income or gain which are specially allocated pursuant to Section 5.05; and shall be debited with all Losses allocated to such Member pursuant to Section 5.04, any items of loss or deduction of the Company specially allocated to such Member pursuant to Section 5.05, and all cash and the Carrying Value of any property (net of liabilities assumed by such Member and the liabilities to which such property is subject) distributed by the Company to such Member. Any references in any Section of this Agreement to the Capital Account of a Member shall be deemed to refer to such Capital Account as the same may be credited or debited from time to time as set forth above. In the event of any transfer of any interest in the Company in accordance with the terms of this Agreement, the Transferee shall succeed to the Capital Account of the transferor to the extent it relates to the transferred interest. Upon the vesting of any Earnout Units upon an Earnout Vesting Event, the parties intend that the allocations and capital maintenance rules shall be governed under Treasury Regulations Section 1.704-3 with adjustments being made in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s) and consistent with the principles of Section 704(c) of the Code and the Treasury Regulations thereunder in order to effectuate the Members’ agreed upon economic sharing of items within the Company.

Section 5.04. Allocations of Profits and Losses. Except as otherwise provided in this Agreement, Profits and Losses (and, to the extent necessary, individual items of income, gain or loss or deduction of the Company) shall be allocated in a manner such that the Capital Account of each Member after giving effect to the special allocations set forth in Section 5.05 is, as nearly as possible, equal (proportionately) to

(i) the distributions that would be made pursuant to Section 9.03 if the Company were dissolved, its affairs wound up and its assets sold for cash equal to their Carrying Value in a hypothetical liquidation, all Company liabilities were satisfied (limited with respect to each non-recourse liability to the Carrying Value of the assets securing such liability) and the net assets of the Company were distributed to the Members pursuant to this Agreement, minus (ii) such Member’s share of Company Minimum Gain and Member Nonrecourse Debt

G-20

Minimum Gain, computed immediately prior to the hypothetical sale of assets. Notwithstanding the foregoing, such allocations may be adjusted as reasonably deemed necessary by the Managing Member, acting in good faith, to give economic effect to the provisions of this Agreement.

Section 5.05. Special Allocations. Notwithstanding any other provision in this Article V:

(a) Minimum Gain Chargeback. If there is a net decrease in Company Minimum Gain or Member Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any Company taxable year, the Members shall be specially allocated items of Company income and gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 5.05(a) is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and shall be interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

(b) Qualified Income Offset. If any Member unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Company income and gain shall be specially allocated to such Member in an amount and manner sufficient to eliminate the deficit balance in such Member’s Adjusted Capital Account Balance created by such adjustments, allocations or distributions as promptly as possible; provided that an allocation pursuant to this Section 5.05(b) shall be made only to the extent that a Member would have a deficit Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if this Section 5.05(b) were not in this Agreement. This Section 5.05(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

(c) Gross Income Allocation. If any Member has a deficit Capital Account at the end of any taxable year which is in excess of the sum of (i) the amount such Member is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Member is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Section 1.704-2(g)(1) and 1.704- 2(i)(5), each such Member shall be specially allocated items of Company income and gain in the amount of such excess as quickly as possible; provided that an allocation pursuant to this Section 5.05(c) shall be made only if and to the extent that a Member would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article V have been tentatively made as if Section 5.05(b) and this Section 5.05(c) were not in this Agreement.

(d) Nonrecourse Deductions. Nonrecourse Deductions shall be allocated to the Members in accordance with their interests in the Company.

(e) Member Nonrecourse Deductions. Member Nonrecourse Deductions for any taxable period shall be allocated to the Member who bears the economic risk of loss with respect to the liability to which such Member Nonrecourse Deductions are attributable in accordance with Treasury Regulations Section 1.704-2(j).

(f) Ameliorative Allocations. Any special allocations of income or gain pursuant to Sections 5.05(b) or 5.05(c) hereof shall be taken into account in computing subsequent allocations pursuant to Section 5.04 and this Section 5.05(f), so that the net amount of any items so allocated and all other items allocated to each Member shall, to the extent possible, be equal to the net amount that would have been allocated to each Member if such allocations pursuant to Sections 5.05(b) or 5.05(c) had not occurred.

(g) Notwithstanding anything to the contrary contained in this Agreement, (1) no allocation (of Profits or Losses or otherwise) shall be made in respect of any Earnout Units in determining Capital Accounts unless and

G-21

until such Units are vested upon the occurrence of an Earnout Vesting Event, if any, and (2) in the event the Carrying Value of any Company asset is adjusted pursuant to clause (d) of the definition of Carrying Value, any Profits or Losses resulting from such adjustment shall, in the manner reasonably determined by the Managing Member, be allocated among the Members such that the Capital Account balance relating to each Class A Unit (excluding any Unvested Earnout Units) is equal in amount immediately after making such allocation, after taking into account the non-distribution amounts (as applicable) in accordance with principles similar to those set forth in Treasury Regulations Section 1.704- 1(b)(2)(iv)(s); provided, that if the foregoing allocations pursuant to clause (2) are insufficient to cause the Capital Account balance relating to each Class A Unit to be so equal in amount, then the Managing Member, in its reasonable discretion, shall cause a Capital Account reallocation in accordance with principles similar to those set forth in Treasury Regulations Section 1.704-1(b)(2)(iv)(s)(3) to cause the Capital Account balance relating to each Class A Unit to be so equal in amount.

Section 5.06. Tax Allocations. For U.S. federal income tax purposes, each item of income, gain, loss and deduction of the Company shall be allocated among the Members in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided that in the case of any asset the Carrying Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss and deduction with respect to such asset shall be allocated, solely for income tax purposes, to account for such difference using the “traditional method” without curative allocations under Treasury Regulations Section 1.704-3(b). Section 5.07. Tax Advances. To the extent the Managing Member reasonably believes that the Company is required by law to withhold or to make tax payments on behalf of or with respect to any Member, or the Company is subjected to tax itself by reason of the status of any Member (including any taxes paid pursuant to Section 6225 of the Code) (“Tax Advances”), the Managing Member may cause the Company to withhold such amounts and cause the Company to make such tax payments as so required. All Tax Advances made on behalf of a Member shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Member or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Member. For all purposes of this Agreement such Member shall be treated as having received the amount of the distribution that is equal to the Tax Advance. Each Member hereby agrees to indemnify and hold harmless the Company and the other Members from and against any liability (including any liability for taxes, penalties, additions to tax or interest, but excluding any penalties, additions to tax or interest imposed as a result of the Company’s failure to withhold or make a tax payment on behalf of such Member which withholding or payment is required pursuant to applicable Law) with respect to income or Tax Advances attributable to such Member; provided, that any remaining Tax Advance with respect to any Member shall be required to be repaid by such Member in full prior to or in connection with (and as a condition of) any Transfer or any Class A Exchange. The obligation of a Member set forth in this Section 5.07 shall survive the withdrawal of a Member from the Company or any Transfer of a Member’s interest.

Section 5.08. Tax Matters. The Managing Member shall act as or designate a Person to act as the “partnership representative” pursuant to the Partnership Audit Provisions (the “Partnership Representative”) and such Person shall have the power to exercise any and all rights that it is or may be entitled to exercise in that capacity. The Partnership Representative shall keep the Continuing Members timely and reasonably informed as to all material tax audits, actions, examinations or proceedings relating to the Company or any of its Subsidiaries (“Tax Proceedings”). The Partnership Representative shall have the exclusive right to represent the Company in respect of any Tax Proceedings. The Members shall cooperate as reasonably requested by the Partnership Representative in connection with any election or decision made by the Partnership Representative acting in that capacity (including by filing amended tax returns and providing information requested).

Section 5.09. Other Allocation Provisions. Certain of the foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b) and shall be interpreted and applied in a manner consistent with such regulations. In addition to amendments effected in accordance with Section 11.12 or otherwise in accordance with this Agreement, Sections 5.03, 5.04 and 5.05 may also, so long as any such amendment does not materially change

G-22

the relative economic interests of the Members and the prior written consent of the Continuing Member Representative has been obtained, be amended at any time by the Managing Member if necessary, in the opinion of tax counsel to the Company, to comply with such regulations or any applicable Law.

With respect to any schedules, annexes or exhibits to this Agreement, each Member (other than the Managing Member) shall only be entitled to receive and review any such schedules, annexes and exhibits relating to such Member and shall not be entitled to receive or review any schedules, annexes or exhibits relating to any other Member (other than the Managing Member).

Upon the occurrence of (i) a Tier 1 Earnout Vesting Event, with respect to the Tier 1 Earnout Units, (ii) a Tier 2 Earnout Vesting Event, with respect to the Tier 2 Earnout Units or (iii) a Tier 3 Earnout Vesting Event, with respect to the Tier 3 Earnout Units, such Earnout Units shall immediately and automatically without any further action on the part of the holder thereof or any other Person (including the Company and the Managing Member) vest and thereafter shall have all rights and privileges of a Class A Unit under this Agreement from and after the Earnout Vesting Date (together with the right to receive any applicable distributions under Section 4.01(b)).

(ii) To the extent that, on or before the fifth (5th) anniversary of the Effective Date, an applicable Earnout Vesting Event has not occurred with respect to an Earnout Unit (and as a result such Earnout Unit is an Unvested Earnout Unit), then immediately and without any further action under this Agreement, on the date that is the fifth (5th) anniversary of the Effective Date, any such Earnout Units shall automatically be forfeited and surrendered to the Company and be canceled and extinguished for no consideration and each corresponding share of Class B Common Stock shall automatically be forfeited and surrendered to Pubco and be canceled and extinguished for no consideration.

Restricted stock granted under any such employee benefit plan shall be treated as outstanding for purposes of Section 7.01(g)(i).

(iii) In the event any outstanding Equity Security of Pubco is exercised or otherwise converted and, as a result, any shares of Class A Common Stock or other Equity Securities of Pubco are issued, (x) the corresponding Equity Security outstanding at the Company, if any, shall be similarly exercised or otherwise converted, if applicable, (y) an equivalent number of Class A Units or equivalent Equity Securities of the Company shall be issued to Pubco, and (z) Pubco shall concurrently contribute to the Company, the net proceeds received by Pubco from any such exercise or conversion (provided, that, the Company shall not be required to reimburse hereunder any costs or expenses which were netted off the gross proceeds received).

(h) Pubco Debt Issuance. If at any time Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) issues Debt Securities, Pubco or such Subsidiary shall transfer to the Company, the net proceeds received by Pubco or such Subsidiary, as applicable, in exchange for such Debt Securities in a manner that directly or indirectly burdens the Company with the repayment of the Debt Securities (provided, that, the Company shall not be required to reimburse hereunder any costs or expenses which were netted off the gross proceeds received).

(i) New Company Issuances. Except pursuant to Section 8.04, (x) the Company may not issue any additional Units to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers an equal number of newly-issued shares of Class A Common Stock (or relevant Equity Security of such Subsidiary) to another Person or Persons, and (ii) such issuance is in accordance with Section 7.01(g), and (y) the Company may not issue any other Equity Securities of the Company to Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless (i) substantially simultaneously therewith Pubco or such Subsidiary issues or transfers, to another Person, an equal number of newly-issued shares of Equity Securities of Pubco or such Subsidiary with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of the Company, and (ii) such issuance is in accordance with Section 7.01(g).

G-26

simultaneously therewith, the Company shall redeem, repurchase or otherwise acquire from Pubco or such Subsidiary an equal number of the corresponding class or series of Equity Securities of the Company with the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of Pubco or such Subsidiary for the same price per security, if any, and substantially equivalent form of consideration.

(ii) The Company may not redeem, repurchase or otherwise acquire (x) any Class A Units from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) an equal number of shares of Class A Common Stock for the same price per security from holders thereof or (y) any other Equity Securities of the Company from Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) unless substantially simultaneously Pubco or such Subsidiary redeems, repurchases or otherwise acquires pursuant to a repurchase plan or program approved by the Board of Directors (or otherwise in connection with a transaction approved by the Board of Directors) for the same price, and substantially equivalent form of consideration, per security an equal number of Equity Securities of Pubco (or such Subsidiary) of a corresponding class or series with substantially the same rights to dividends and distributions (including distributions upon liquidation) and other economic rights as those of such Equity Securities of Pubco or such Subsidiary.

(iii) Notwithstanding the foregoing clauses (i) and (ii), to the extent that any consideration payable by Pubco in connection with the redemption, repurchase or acquisition of any shares of Class A Common Stock or other Equity Securities of Pubco or any of its Subsidiaries (other than the Company and its Subsidiaries) consists (in whole or in part) of shares of Class A Common Stock or such other Equity Securities (including in connection with the cashless exercise of an option or warrant (or other convertible right or security)) other than under Pubco’s employee benefit plans for which there is no corresponding Class A Units or other Equity Securities of the Company, then the redemption, repurchase or acquisition of the corresponding Class A Units or other Equity Securities of the Company shall be effectuated in an equivalent manner.

(k) Equity Subdivisions and Combinations.

(i) The Company shall not in any manner effect any subdivision (by any equity split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of the outstanding Units unless approved by the Board of Directors and accompanied by an identical subdivision or combination, as applicable, of the outstanding Pubco Common Stock or other related class or series of Equity Security of Pubco, with corresponding changes made with respect to any other exchangeable or convertible Equity Securities of the Company and Pubco.

(ii) Except in accordance with Section 8.04(c), Pubco shall not in any manner effect any subdivision (by any equity split, equity distribution, reclassification, recapitalization or otherwise) or combination (by reverse equity split, reclassification, recapitalization or otherwise) of the outstanding Pubco Common Stock or any other class or series of Equity Security of Pubco, unless approved by the Board of Directors and accompanied by an identical subdivision or combination, as applicable, of the outstanding Units or other related class or series of Equity Security of the Company, with corresponding changes made with respect to any applicable exchangeable or convertible Equity Securities of the Company and Pubco.

G-27

be permitted to undertake all actions, including an issuance, redemption, reclassification, distribution, division or recapitalization, with respect to the Units to maintain at all times a one-to-one ratio between (i) the number of Class A Units owned by Pubco and its Subsidiaries (excluding the Company’s Subsidiaries), directly or indirectly, and the number of outstanding shares of Class A Common Stock, and (ii) the number of outstanding shares of Class B Common Stock held by any Person and the number of Class A Units held by such Person (other than Pubco or any of its Subsidiaries, but excluding the Company’s Subsidiaries), disregarding, for purposes of maintaining the one-to-one ratios in clause (i), (A) options, rights or securities of Pubco issued under any plan involving the issuance of any Equity Securities that are convertible into or exercisable or exchangeable for Class A Common Stock, (B) treasury stock, or (C) preferred stock or other debt or equity securities (including warrants, options or rights) issued by Pubco that are convertible or into or exercisable or exchangeable for Class A Common Stock (but in each case prior to such conversion or exchange).

Section 7.02. Register; Certificates; Legends. The Company shall maintain a schedule of Units, other Company securities and all Members setting forth: (i) the name and address of each Member; (ii) the aggregate number of Units and the aggregate number of each Class or series of Units or other Company securities; (iii) the aggregate number of Units and the aggregate number of each Class or series of Units or other Company securities held by each Member or Assignee; and (iv) the Capital Contributions made or deemed made by each Member (such schedule, as amended and/or restated in accordance with this Agreement, the “Schedule of Members”). To the fullest extent permitted by applicable Law, the Schedule of Members shall be the definitive record of ownership of each Unit and all relevant information with respect to each Member. Unless the Managing Member in its sole discretion shall determine otherwise, Units shall be uncertificated and recorded in the Schedule of Members. Certificates, if any, representing Units that are issued to any Member shall bear a legend in substantially the following form:

THE SECURITIES PRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY OTHER STATE OR FOREIGN SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD, OR TRANSFERRED EXCEPT IN COMPLIANCE THEREWITH THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE ALSO SUBJECT TO ADDITIONAL RESTRICTIONS ON TRANSFER AS SET FORTH IN THE SECOND AMENDED AND RESTATED LIMITED LIABILITY COMPANY AGREEMENT OF FATHOM HOLDCO, LLC DATED AS OF [•], AS AMENDED FROM TIME TO TIME A COPY OF WHICH WILL BE FURNISHED BY FATHOM HOLDCO, LLC UPON REQUEST.

Section 7.03. Registered Members. The Company shall be entitled to recognize the exclusive right of a Person listed on the Schedule of Members as the owner of Units for all purposes and shall not be bound to recognize any equitable or other claim to or interest in Units on the part of any other Person, whether or not it shall have express or other notice thereof, except as otherwise provided by the Act or other applicable Law.

Section 7.04. Reclassification Events of Pubco. If a Reclassification Event occurs, the Managing Member or its successor as a result of such Reclassification Event, as the case may be, shall, as and to the extent necessary, amend this Agreement in compliance with Section 11.12, and enter into any necessary supplementary or additional agreements, to ensure that, following the effective date of the Reclassification Event: (a) the exchange rights of holders of Units set forth in Section 8.04 provide that each Class A Unit (together with the surrender and delivery of one (1) share of Class B Common Stock) is exchangeable for the same amount and same type of property, securities or cash (or combination thereof) that one (1) share of Class A Common Stock (subject to Section 8.04(c)) becomes exchangeable for or converted into as a result of the Reclassification Event and (b) Pubco or the successor to Pubco as a result of such Reclassification Event, as applicable, is obligated to deliver such property, securities or cash upon such exchange. Pubco shall not consummate or agree to consummate any Reclassification Event unless the successor Person as a result of such Reclassification Event, if any, becomes obligated to comply with the obligations of Pubco (in whatever capacity) under this Agreement.

EXCHANGES; TRANSFER RESTRICTIONS

Section 8.01. [Reserved.]

Section 8.02. [Reserved.]

Section 8.03. Member Transfers.

(a) No Member shall be permitted to Transfer all or any portion of its Units, except Transfers made in accordance with the provisions of Section 8.03(b). If, notwithstanding the provisions of this Section 8.03(a), all or any portion of a Member’s Units are Transferred by such Member in violation of this Section 8.03(a), involuntarily, by operation of Law or otherwise, the Transferee of such Units (or portion thereof) shall not be admitted to the Company as a Member nor be entitled to any rights as a Member under this Agreement, and the Transferor will continue to be bound by all obligations under this Agreement. Any attempted or purported Transfer of all or a portion of a Member’s Units in violation of this Section 8.03(a) shall, to the fullest extent permitted by Law, be null and void ab initio and of no force or effect whatsoever. Subject to the restrictions set forth herein, (i) no shares of Class B Common Stock may be Transferred by a Member unless an equal number of Class A Units are Transferred therewith in accordance with this Agreement (including in respect of those Transfers permitted by Section 8.03(b)), and (ii) no Class A Units may be Transferred by a Member holding Class B Common Stock unless an equal number of shares of Class B Common Stock are Transferred therewith in accordance with this Agreement (including in respect of those Transfers permitted by Section 8.03(b)).

(b) The Transfer restrictions contained in Section 8.03(a) shall not apply to any Transfer (each, a “Permitted Transfer”): (i) in connection with a Class A Exchange effected in accordance with the provisions of this Agreement, (ii) by a Member to Pubco or any of its wholly-owned Subsidiaries, or (iii) by a Member to any of such Member’s Permitted Transferees, in each case, in accordance with this Section 8.03, provided, however, that, following any Permitted Transfer pursuant to clause (iii), the restrictions contained in this Agreement will continue to apply to such Units and, as a condition to such Transfer, the Transferee shall be required to execute a joinder to this Agreement and agree in writing to be bound by the provisions of this Agreement. In the case of a Permitted Transfer of any Class A Units by a Continuing Member, such Transferring Member shall be required to Transfer an equal number of shares of Class B Common Stock to such Transferee. All Permitted Transfers are subject to the additional limitations set forth in Section 8.06.

Section 8.04. Class A Exchanges.

(a) Right to Exchange for Class A Common Stock.

(i) Subject to adjustment as provided in Section 8.04(c), to any restrictions imposed by the Managing Member as provided in Section 8.06(b) and to the provisions of this Agreement, each Member holding Class A Units (together with its Affiliates, including other Continuing Members, and Permitted Transferees), other than the Managing Member and its Subsidiaries who shall not have the right to effect a Class A Exchange, (i) that is not a CORE Party or an Affiliate or Permitted Transferee thereof, shall be entitled to cause the Company to effect a Class A Exchange up to one (1) time per calendar quarter by delivering a Class A Exchange Notice to the Company and the Managing Member and (ii) that is a CORE Party or any Affiliate or Permitted Transferee thereof shall be entitled to cause the Company to effect a Class A Exchange up to two (2) times per calendar quarter, collectively, by delivering a Class A Exchange Notice to the Managing Member and to the Company. Any Class A Exchange under this Section 8.04 must be with respect to a number of Class A Units at least equal to the Maximum Exchange Amount.

(ii) For the avoidance of doubt, Unvested Earnout Units are not permitted to be exchanged pursuant to this Section 8.04, and in no event shall the Company or Pubco effect an exchange of an Earnout Unit unless and until an Earnout Vesting Event and Earnout Vesting Date has occurred with respect to such Earnout Unit and it has vested in accordance with the terms hereof.

G-29

(b) Exchange Procedures.

(i) A Class A Exchanging Member shall exercise its right to make a Class A Exchange as set forth in Section 8.04(a) above by providing such Class A Exchange Notice during normal business hours at the principal executive office of Pubco and the Company (or otherwise in accordance with Section 11.02). Within three (3) Business Days following its receipt of a Class A Exchange Notice, the Managing Member may elect to settle all or a portion of the Class A Exchanged Units in cash in an amount equal to the Class A Cash Amount (in lieu of shares of Class A Common Stock), by giving written notice of such election to the Class A Exchanging Member within such three (3) Business Day period (such notice, the “Cash Exchange Notice”). The Cash Exchange Notice shall set forth the portion of the Class A Exchanged Units subject to the Class A Exchange which shall be exchanged for cash in lieu of Class A Common Stock. To the extent any Class A Exchange relates to the exercise of the Class A Exchanging Member’s registration rights under the Registration Rights Agreement, Pubco and the Company shall cooperate in good faith with such Class A Exchanging Member to exercise such Class A Exchange in a manner which preserves such Class A Exchanging Member’s rights thereunder. At any time following the delivery of a Cash Exchange Notice and prior to the Class A Exchange Date, the Managing Member may elect (by giving written notice of such election to the Class A Exchanging Member) to revoke the Cash Exchange Notice with respect to all or any portion of the Class A Exchanged Units and instead deliver the applicable Class A Exchanged Shares with respect to any such Class A Exchanged Units on the Class A Exchange Date.

(ii) [Reserved].

(iii) Each Class A Exchange shall be consummated on the Class A Exchange Date. On the Class A Exchange Date (to be effective immediately prior to the close of business on the Class A Exchange Date), (a) Pubco shall contribute to the Company for delivery to the Class A Exchanging Member (x) the Class A Exchanged Shares with respect to such Class A Exchanged Units not subject to a Cash Exchange Notice and (y) the Class A Cash Amount with respect to any Class A Exchanged Units subject to a Cash Exchange Notice, (b) the Class A Exchanging Member shall transfer and surrender the Class A Exchanged Units to the Company, free and clear of all liens and encumbrances, (c) the Company shall issue to Pubco a number of Class A Units equal to the number of shares of Class A Common Stock to be delivered pursuant to clause (a)(x), (d) solely to the extent necessary in connection with a Class A Exchange, Pubco shall undertake all actions, including an issuance, reclassification, distribution, division or recapitalization, with respect to the Class A Common Stock necessary in order to maintain a one-to-one ratio between the number of Class A Units owned by Pubco, directly or indirectly, and the number of outstanding shares of Class A Common Stock, taking into account the issuance in clause (c), any Class A Exchanged Shares, and any other action taken in connection with this Section 8.04, (e) the Company shall (x) cancel the redeemed Class A Units which were Class A Exchanged Units held by the Class A Exchanging Member and (y) transfer to the Class A Exchanging Member the Class A Cash Amount and/or the Class A Exchanged Shares, as applicable, and (f) Pubco shall cancel the surrendered shares of Class B Common Stock. Upon the Class A Exchange of all of a Member’s Class A Units, such Class A Member shall cease to be a Class A Member of the Company.

(iv) The Company and each Class A Exchanging Member shall bear their own expenses in connection with the consummation of any Class A Exchange, except that the Company shall bear any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, any Class A Exchange; provided, however, that if any shares of Class A Common Stock are to be delivered in a name other than that of the Class A Exchanging Member, then such Class A Exchanging Member and/or the person in whose name such shares are to be delivered shall pay to the Company the amount of any transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange or shall establish to the reasonable satisfaction of the Company that such tax has been paid or is not payable (and shall indemnify the Company in the event such transfer taxes, stamp taxes or duties, or other similar taxes in connection with, or arising by reason of, such Class A Exchange are not so paid).

G-30

(v) Pubco may adopt reasonable procedures for the implementation of the Class A Exchange provisions set forth in this Section 8.04; provided that without the consent of each Continuing Member, Pubco shall not adopt any procedures inconsistent with or that impair or adversely affect the rights of a Member to Exchange Class A Units pursuant to this Agreement. A Class A Exchanging Member may not revoke a Class A Exchange Notice delivered pursuant to Section 8.04(a) above without the consent of the Managing Member, which consent may not be unreasonably withheld, delayed or conditioned.

(vi) Notwithstanding anything to the contrary herein, additional restrictions may be imposed on Class A Exchanges by the Managing Member as provided in Section 8.06(b).

(c) Adjustment. If there is: (i) any subdivision (by any unit split, unit distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse unit split, reclassification, reorganization, recapitalization or otherwise) of the Class A Units that is not accompanied by an identical subdivision or combination of the Class A Common Stock; or (ii) any subdivision (by any stock split, stock dividend or distribution, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse stock split, reclassification, reorganization, recapitalization or otherwise) of the Class A Common Stock that is not accompanied by an identical subdivision or combination of the Units, then, in each case, to the extent necessary to maintain the economic equivalency in the value surrendered for exchange and the value received, the Managing Member shall in good faith adjust the number of shares of Class A Common Stock for which a Class A Unit is entitled to be exchanged under this Section 8.04 accordingly. If there is any reclassification, reorganization, recapitalization or other similar transaction in which the Class A Common Stock is converted or changed into another security, securities or other property, then upon any subsequent Class A Exchange, a Class A Exchanging Member shall be entitled to receive the amount of such security, securities or other property that such Class A Exchanging Member would have received if such Class A Exchange had occurred immediately prior to the effective date of such reclassification, reorganization, recapitalization or other similar transaction, taking into account any adjustment as a result of any subdivision (by any split, distribution or dividend, reclassification, reorganization, recapitalization or otherwise) or combination (by reverse split, reclassification, recapitalization or otherwise) of such security, securities or other property that occurs after the effective time of such reclassification, reorganization, recapitalization or other similar transaction. Except as may be required in the immediately preceding sentence, no adjustments in respect of distributions shall be made upon a Class A Exchange.

(d) Class A Common Stock to be Issued.

(i) Pubco shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the purpose of issuance upon a Class A Exchange, such number of shares of Class A Common Stock as shall be deliverable upon any such Class A Exchange; provided that nothing contained herein shall be construed to preclude the Company from satisfying its obligations in respect of the Class A Exchange by delivery of shares of Class A Common Stock which are held in the treasury of Pubco or any of its subsidiaries (other than the Company or any of its subsidiaries) or by delivery of purchased shares of Class A Common Stock (which may or may not be held in the treasury of Pubco or any subsidiary thereof). Pubco and the Company covenant that all Class A Common Stock issued upon a Class A Exchange will, upon issuance, be validly issued, fully paid and non-assessable.

(ii) Pubco and the Company covenant and agree that, to the extent that a Registration Statement under the Securities Act is effective and available for shares of Class A Common Stock to be delivered with respect to any Class A Exchange, shares that have been registered under the Securities Act shall be delivered in respect of such Class A Exchange. In the event that any Class A Exchange in accordance with this Agreement is to be effected at a time when any required registration has not become effective or otherwise is unavailable, upon the request and with the reasonable cooperation of the applicable Class A Exchanging Member, Pubco and the Company shall use commercially reasonable efforts to promptly facilitate such Exchange pursuant to any reasonably available exemption from such registration requirements. Pubco and the Company shall use

G-31

commercially reasonable efforts to list the Class A Common Stock required to be delivered upon a Class A Exchange prior to such delivery upon each national securities exchange or inter-dealer quotation system upon which the outstanding Class A Common Stock may be listed or traded at the time of such delivery.

(e) Pubco Offers. In the event that a tender offer, share exchange offer, or take-over bid or similar transaction with respect to Class A Common Stock or another Equity Security of Pubco (a “Pubco Offer”) is proposed by Pubco or is proposed to Pubco or its stockholders, the holders of Class A Units (or such other Equity Security of the Company corresponding to such Pubco Equity Security) shall be permitted to participate in such Pubco Offer by delivery of a Class A Exchange Notice (which Class A Exchange Notice shall be effective immediately prior to the consummation of such Pubco Offer (and, for the avoidance of doubt, shall be contingent upon such Pubco Offer and not be effective if such Pubco Offer is not consummated)). In the case of a Pubco Offer, Pubco shall use its reasonable best efforts to take all such actions and do all such things as are necessary or desirable to enable and permit the holders of Class A Units or other Equity Security to participate in such Pubco Offer to the same extent or on an economically equivalent basis as the holders of shares of Class A Common Stock or other Equity Security without discrimination; provided that, without limiting the generality of this sentence (and without limiting the ability of any Member holding Class A Units or such other Equity Security to consummate a Class A Exchange at any time pursuant to the terms of this Agreement), the Managing Member shall use its reasonable best efforts to ensure that such holders of Class A Units or such other Equity Security may participate in such Pubco Offer without being required to effect a Class A Exchange of their Class A Units and cancel their shares of Class B Common Stock, as the case may be, (or, if so required, to ensure that any such Class A Exchange and cancelation shall be effective only upon, and shall be conditional upon, the closing of the transactions contemplated by the Pubco Offer). For the avoidance of doubt, in no event shall the holders of Class A Units be entitled to receive in such Pubco Offer aggregate consideration for each Class A Unit and share of Class B Common Stock, taken together, that is greater than or less than the consideration payable in respect of each share of Class A Common Stock in connection with such Pubco Offer (it being understood that payments under or in respect of the Tax Receivable Agreement shall not be considered part of any such consideration, and shall be in addition thereto).

(f) Pubco Call Rights. Notwithstanding anything to the contrary contained in this Section 8.04, with respect to any Class A Exchange Notice, a Class A Exchanging Member shall be deemed to have offered to sell its Class A Exchanged Units as described in any Class A Exchange Notice directly to Pubco (rather than to the Company), and Pubco may, by delivery of a written notice to the Class A Exchanging Member no later than three (3) Business Days following the giving of a Class A Exchange Notice, in accordance with, and subject to the terms of, this Section 8.4(f) (such notice, a “Pubco Call Notice”), elect to purchase directly and acquire such Class A Exchanged Units on the Class A Exchange Date by paying to the Class A Exchanging Member (or such other Person specified in the Class A Exchange Notice) the Class A Exchanged Shares and/or Class A Cash Amount with respect to the Class A Exchanged Units, whereupon Pubco shall acquire the Class A Exchanged Units on the Class A Exchange Date and be treated for all purposes of this Agreement as the owner of such Class A Units. Except as otherwise provided in this Section 8.04(f), an exercise of the call right of Pubco set forth in this Section 8.04(f) shall be consummated pursuant to the same timeframe and in the same manner as the relevant Class A Exchange would have been consummated if Pubco had not given a Pubco Call Notice, in each case as relevant.

(g) Distribution Rights. No Class A Exchange shall impair the right of the Class A Exchanging Member to receive any distributions payable on the Units redeemed pursuant to such Class A Exchange in respect of a record date that occurs prior to the Class A Exchange Date for such Class A Exchange. No Class A Exchanging Member, or a Person designated by a Class A Exchanging Member to receive shares of Class A Common Stock, shall be entitled to receive, with respect to such record date, distributions or dividends both on Class A Units redeemed by the Company from such Class A Exchanging Member and on shares of Class A Common Stock received by such Class A Exchanging Member, or other Person so designated, if applicable, in such Class A Exchange.

G-32

(h) Tax Treatment. For U.S. federal and applicable state and local income tax purposes, each of the Class A Exchanging Member, the Company and Pubco agree to treat each Class A Exchange as a sale by the Class A Exchanging Member of the Class A Exchanging Member’s Class A Units (together with a corresponding number of outstanding shares of Class B Common Stock, which shares shall not be allocated economic value in excess of par value) to Pubco in exchange for the Class A Common Stock.

Section 8.06. Further Restrictions.

(a) Notwithstanding any contrary provision in this Agreement, other than with respect to Transfers in accordance with Section 8.04, in no event may any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that:

(i) such Transfer is made to any Person who lacks the legal right, power or capacity to own such Unit;

(ii) such Transfer would require the registration of such transferred Unit or of any Class of Unit pursuant to any applicable U.S. federal or state securities laws (including, without limitation, the Securities Act or the Exchange Act) or other non-U.S. securities laws (including Canadian provincial or territorial securities laws) or would constitute a non-exempt distribution pursuant to applicable provincial or state securities laws; or

(iii) such Transfer would cause (i) all or any portion of the assets of the Company to (A) constitute “plan assets” (under ERISA, the Code or any applicable Similar Law) of any existing or contemplated Member, or (B) be subject to the provisions of ERISA, Section 4975 of the Code or any applicable Similar Law, or (ii) the Managing Member to become a fiduciary with respect to any existing or contemplated Member, pursuant to ERISA, any applicable Similar Law, or otherwise.

(b) Notwithstanding any contrary provision in this Agreement, in no event shall any Transfer of a Unit be made by any Member or Assignee if the Managing Member determines in its reasonable discretion that such Transfer would pose a material risk that such Transfer would (i) be considered to be effected on or through an “established securities market” or a “secondary market or the substantial equivalent thereof” as such terms are used in Treasury Regulations Section 1.7704-1, (ii) result in the Company having more than 100 partners, within the meaning of Treasury Regulations Section 1.7704-1(h) (determined taking into account the rules of Treasury Regulations Section 1.7704-1(h)(3)), or (iii) cause the Company to be treated as a “publicly traded partnership” within the meaning of Section 7704 of the Code and the Treasury Regulations promulgated thereunder. In addition, notwithstanding any contrary provision in this Agreement, to the extent the Managing Member reasonably determines that additional restrictions on Transfers (including, for the avoidance of doubt, Class A Exchanges) are advisable to minimize the risk that the Company is not treated as a “publicly traded partnership” under Section 7704 of the Code, the Managing Member shall impose such additional restrictions on Transfers as the Managing Member reasonably determines to be so advisable.

(c) To the fullest extent permitted by law, any Transfer in violation of this Article VIII shall be deemed null and void ab initio and of no effect.

Section 8.07. Rights of Assignees. The Transferee of any Permitted Transfer permitted pursuant to this Article VIII will be an assignee only (“Assignee”), and only will receive, to the extent transferred, the distributions and allocations of income, gain, loss, deduction, credit or similar item to which the Member which transferred its Units would be entitled, and such Assignee will not be entitled or enabled to exercise any other rights or powers of a Member, such other rights, and all obligations relating to, or in connection with, such interest remaining with the transferring Member, unless and until such time as such Transferee is admitted to the Company as a Member pursuant to Section 8.09. The transferring Member will remain a Member even if it has transferred all of its Units to one or more Assignees until such time as all such Assignee(s) have been admitted to the Company as a Member pursuant to Section 8.09.

Section 8.08. Admissions, Resignations and Removals.

(a) Pubco shall not, by any means, resign as, cease to be or be replaced as Managing Member except in compliance with this Section 8.08 and except with the approval of a majority of the independent directors serving on the Board of Directors. No termination or replacement of Pubco as Managing Member shall be effective unless proper provision is made, in compliance with this Agreement, so that the obligations of Pubco, its successor by merger (if applicable) and any new Managing Member and the rights of all Members under this Agreement and applicable Law remain in full force and effect. No appointment of a Person other than Pubco (or its successor by merger, as applicable) as Managing Member shall be effective unless (a) the new Managing Member executes a joinder to this Agreement and agrees to be bound by the terms and conditions in this Agreement, and (b) Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable) provide all other Members with contractual rights, directly enforceable by such other Members against Pubco (or its successor by merger, as applicable) and the new Managing Member (as applicable), to cause (i) Pubco to comply with all Pubco’s obligations under this Agreement (including its obligations under Section 8.04 and 7.01(c)(iii)) other than those that must necessarily be taken solely in its capacity as Managing Member and (ii) the new Managing Member to comply with all the Managing Member’s obligations under this Agreement.

(b) No Member will be removed or entitled to resign from being a Member of the Company except in accordance with Section 8.10 hereof. Any additional Managing Member or substitute Managing Member admitted as a Managing Member of the Company pursuant to this Section 8.08 is hereby authorized to, and shall, continue the Company without dissolution.

(c) Except as otherwise provided in Article IX or the Act, no admission, substitution, resignation or removal of a Member will cause the dissolution of the Company. To the fullest extent permitted by law, any purported admission, resignation or removal that is not in accordance with this Agreement shall be null and void.

Section 8.09. Admission of Assignees as Substitute Members. An Assignee will become a substitute Member only if and when each of the following conditions is satisfied:

(a) the Managing Member consents in writing to such admission (to the extent required in accordance with Section 8.03);

(b) if required by the Managing Member, the Managing Member receives written instruments (including, without limitation, copies of any instruments of Transfer) that are in a form satisfactory to the Managing Member; and

(c) such Assignee signs a joinder or counterpart to this Agreement agreeing to become a party to and bound by this Agreement as a substitute Member.

Section 8.10. Resignation and Removal of Members. Subject to Section 8.07, if a Member (other than the Managing Member) ceases to hold any Units, then such Member shall cease to be a Member and to have the power to exercise any rights or powers of a member of the Company, and shall be deemed to have resigned from the Company.

ARTICLE IX

DISSOLUTION, LIQUIDATION AND TERMINATION

Section 9.01. No Dissolution. Except as required by the Act, the Company shall not be dissolved by the admission of additional Members or resignation of Members in accordance with the terms of this Agreement. The Company may be dissolved, liquidated, wound up and terminated only pursuant to the provisions of this Article IX, and the Members hereby irrevocably waive any and all other rights they may have to cause a dissolution of the Company or a sale or partition of any or all of the Company assets.

G-34

Section 9.02. Events Causing Dissolution. The Company shall be dissolved and its affairs shall

be wound up upon the occurrence of any of the following events (each, a “Dissolution Event”):

(a) the entry of a decree of judicial dissolution of the Company under Section 18-802 of the Act upon the finding by a court of competent jurisdiction that it is not reasonably practicable to carry on the business of the Company in conformity with this Agreement;

(b) any event which makes it unlawful for the business of the Company to be carried on by the Members;

(c) the written consent of all Members;

(d) at any time there are no Members, unless the Company is continued in accordance with the Act; or

(e) the determination of the Managing Member, with the consent of the Continuing Member Representative for so long as the Continuing Members hold Units; provided that in the event of a dissolution pursuant to this clause (e), the relative economic rights of each Class of Units immediately prior to such dissolution shall be preserved to the greatest extent practicable with respect to distributions made to Members pursuant to Section 9.03 below in connection with the winding up of the Company, taking into consideration tax and other legal constraints that may adversely affect one or more parties hereto and subject to compliance with applicable laws and regulations, unless, and to the extent that, with respect to any Class of Units, holders of not less than 75% of the Units of such Class consent in writing to a treatment other than as described above; provided, that prior to the occurrence of a Tier 1 Earnout Vesting Event, a Tier 2 Earnout Vesting Event or a Tier 3 Earnout Vesting Event with respect to the Tier 1 Earnout Units, the Tier 2 Earnout Units and the Tier 3 Earnout Units, respectively, such Units shall not have any economic rights under this Agreement.

Section 9.03. Distribution upon Dissolution. Upon dissolution, the Company shall not be terminated and shall continue until the winding up of the affairs of the Company is completed. Upon the winding up of the Company, the Managing Member, or any other Person designated by the Managing Member (the “Liquidation Agent”), shall take full account of the assets and liabilities of the Company and shall, unless the Managing Member determines otherwise, liquidate the assets of the Company as promptly as is consistent with obtaining the fair value thereof. The proceeds of any liquidation shall be applied and distributed in the following order:

(a) First, to the satisfaction of debts and liabilities of the Company (including satisfaction of all indebtedness to Members and/or their Affiliates to the extent otherwise permitted by law) including the expenses of liquidation, and including the establishment of any reserve which the Liquidation Agent shall deem reasonably necessary for any contingent, conditional or unmatured contractual liabilities or obligations of the Company (“Contingencies”). Any such reserve may be paid over by the Liquidation Agent to any attorney-at-law, or acceptable party, as escrow agent, to be held for disbursement in payment of any Contingencies and, at the expiration of such period as shall be deemed advisable by the Liquidation Agent for distribution of the balance in the manner hereinafter provided in this Section 9.03;

(b) Second, to the satisfaction of (i) any payments due pursuant to Section 4.01(b), if any, to the Members holding Class A Units for which such distributions are due, pro rata in accordance with all such Members’ respective Class A Units for which such distributions are due; and

(c) The balance, if any, to the Members, pro rata in accordance with the Members’ respective Class A Units other than Unvested Earnout Units.

Section 9.04. Time for Liquidation. A reasonable amount of time shall be allowed for the orderly liquidation of the assets of the Company and the discharge of liabilities to creditors so as to enable the Liquidation Agent to minimize the losses attendant upon such liquidation.

G-35

Section 9.05. Termination. The Company shall terminate when all of the assets of the Company, after payment of or due provision for all debts, liabilities and obligations of the Company, shall have been distributed to the holders of Units in the manner provided for in this Article IX, and the Certificate shall have been cancelled in the manner required by the Act.

Section 9.06. Claims of the Members. The Members shall look solely to the Company’s assets for the return of their Capital Contributions, and if the assets of the Company remaining after payment of or due provision for all debts, liabilities and obligations of the Company are insufficient to return such Capital Contributions, the Members shall have no recourse against the Company or any other Member or any other Person. No Member with a negative balance in such Member’s Capital Account shall have any obligation to the Company or to the other Members or to any creditor or other Person to restore such negative balance during the existence of the Company, upon dissolution or termination of the Company or otherwise, except to the extent required by the Act.

Section 9.07. Survival of Certain Provisions. Notwithstanding anything to the contrary in this Agreement, the provisions of Section 5.07, Section 5.08, Section 10.02, Section 11.09 and Section 11.10 shall survive the termination of the Company.

ARTICLE X

LIABILITY AND INDEMNIFICATION

Section 10.01. Liability of Members.

(a) No Member and no Affiliate, manager, member, employee or agent of a Member shall be liable for any debt, obligation or liability of the Company or of any other Member or have any obligation to restore any deficit balance in its Capital Account solely by reason of being a Member of the Company, except to the extent required by the Act.

(b) This Agreement is not intended to, and does not, create or impose any duty (including any fiduciary duty) on any of the Members (other than the Managing Member in its capacity as such) hereto or on their respective Affiliates. Further, notwithstanding any other provision of this Agreement or any duty otherwise existing at law or in equity, the parties hereto agree that no Member (other than the Managing Member, in its capacity as such, as set forth in Section 3.06) shall, to the fullest extent permitted by law, have any duties (including fiduciary duties) to any other Member or to the Company, and in doing so, the parties recognize, acknowledge and agree that their duties and obligations to one another and to the Company are only as expressly set forth in this Agreement; provided, however, that each Member shall have the duty to act in accordance with the implied contractual covenant of good faith and fair dealing.

(c) To the extent that, at law or in equity, any Member has duties (including fiduciary duties) and liabilities relating thereto to the Company, to another Member or to another Person who is a party to or is otherwise bound by this Agreement, the Members (other than the Managing Member in its capacity as such) acting under this Agreement will not be liable to the Company, to any such other Member or to any such other Person who is a party to or is otherwise bound by this Agreement, for their good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they restrict or eliminate the duties and liabilities relating thereto of any Member otherwise existing at law or in equity, are agreed by the Members to replace to that extent such other duties and liabilities of the Members relating thereto.

(d) The Managing Member may consult with legal counsel, accountants and financial or other advisors selected by it, and any act or omission taken by the Managing Member on behalf of the Company or in furtherance of the interests of the Company in good faith in reliance upon and in accordance with the advice of such Person as to matters the Managing Member reasonably believes to be within such Person’s professional or expert competence shall be conclusively presumed to have been done or omitted in good faith and in accordance

G-36

with such opinion or advice, and the Managing Member will be fully protected in so acting or omitting to act so long as such counsel or accountants or financial or other advisors were selected with reasonable care.

Section 10.02. Indemnification.

(a) Exculpation and Indemnification. Notwithstanding any other provision of this Agreement, whether express or implied, to the fullest extent permitted by law, no Indemnitee shall be liable to the Company or any Member for any act or omission in relation to the Company or this Agreement or any transaction contemplated hereby taken or omitted by an Indemnitee in good faith and in the reasonable belief that such act or omission was in the best interests of the Company. To the fullest extent permitted by law, as the same exists or hereafter be amended (but in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the Company to provide prior to such amendment), the Company shall indemnify any Indemnitee who was or is made or is threatened to be made a party to or is otherwise involved in any threatened, pending or completed action, suit or proceeding (brought in the right of the Company or otherwise), whether civil, criminal, administrative, arbitrative or investigative, and whether formal or informal (hereinafter a “Proceeding”), including appeals, by reason of his or her or its status as an Indemnitee or by reason of any action alleged to have been taken or omitted to be taken by an Indemnitee in such capacity, from and against all loss and liability suffered and expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement reasonably incurred by such Indemnitee in connection with such action, suit or proceeding, including appeals; provided that such Indemnitee shall not be entitled to indemnification hereunder if, but only to the extent that, such Indemnitee’s conduct constituted fraud, bad faith, gross negligence or willful misconduct. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to indemnify an Indemnitee in connection with any action, suit or proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member, and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent. The indemnification of an Indemnitee of the type identified in clause (e) of the definition of Indemnitee shall be secondary to any and all indemnification to which such Indemnitee is entitled from the relevant other Person (including any payment made to such Indemnitee under any insurance policy issued to or for the benefit of such Person or Indemnitee) (the “Primary Indemnification”), and will only be paid to the extent the Primary Indemnification is not paid and/or does not provide coverage (e.g., a self-insured retention amount under an insurance policy). No such Person shall be entitled to contribution or indemnification from or subrogation against the Company. The indemnification of any other Indemnitee shall, to the extent not in conflict with such policy, be secondary to any and all payment to which such Indemnitee is entitled from any relevant insurance policy issued to or for the benefit of the Company or any Indemnitee. For the avoidance of doubt, this Agreement shall not affect the indemnification and advancement of rights provided pursuant to the Existing Agreement in favor of any Person relating to proceedings arising out of actions or omissions occurring in whole or in part prior to the effectiveness of this Agreement.

(b) Advancement of Expenses. To the fullest extent permitted by law, the Company shall promptly pay reasonable expenses (including attorneys’ fees) incurred by any Indemnitee in appearing at, participating in or defending any Proceeding in advance of the final disposition of such Proceeding, including appeals, upon presentation of an undertaking on behalf of such Indemnitee to repay such amount if it shall ultimately be determined that such Indemnitee is not entitled to be indemnified under this Section 10.02 or otherwise. Notwithstanding the preceding sentence, except as otherwise provided in Section 10.02(c), the Company shall be required to pay expenses of an Indemnitee in connection with any Proceeding (or part thereof) (i) commenced by such Indemnitee only if the commencement of such action, suit or proceeding (or part thereof) by such Indemnitee was authorized by the Managing Member and (ii) by or in the right of the Company only if the Managing Member has provided its prior written consent.

(c) Unpaid Claims. If a claim for indemnification (following the final disposition of such Proceeding) or advancement of expenses under this Section 10.02 is not paid in full within thirty (30) days after a written claim therefor by any Indemnitee has been received by the Company, such Indemnitee may file proceedings to recover

G-37

the unpaid amount of such claim and, if successful in whole or in part, shall be entitled to be paid the expense of prosecuting such claim. In any such action the Company shall have the burden of proving that such Indemnitee is not entitled to the requested indemnification or advancement of expenses under applicable Law.

(d) Insurance. To the fullest extent permitted by law, the Company may purchase and maintain insurance on behalf of any person described in Section 10.02(a) against any liability asserted against such person, whether or not the Company would have the power to indemnify such person against such liability under the provisions of this Section 10.02 or otherwise.

(i) In the event of any payment by the Company under this Section 10.02, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of the Indemnitee from any relevant other Person or under any insurance policy issued to or for the benefit of the Company, such relevant other Person, or any Indemnitee. Each Indemnitee agrees to execute all papers required and take all action necessary to secure such rights, including the execution of such documents as are necessary to enable the Company to bring suit to enforce any such rights in accordance with the terms of such insurance policy or other relevant document. The Company shall pay or reimburse all expenses actually and reasonably incurred by the Indemnitee in connection with such subrogation.

(ii) The Company shall not be liable under this Section 10.02 to make any payment of amounts otherwise indemnifiable hereunder (including, but not limited to, judgments, fines and amounts paid in settlement, and excise taxes with respect to an employee benefit plan or penalties) if and to the extent that the applicable Indemnitee has otherwise actually received such payment under this Section 10.02 or any insurance policy, contract, agreement or otherwise.

(e) Non-Exclusivity of Rights. The provisions of this Section 10.02 shall be applicable to all actions, claims, suits or proceedings made or commenced after the date of this Agreement, whether arising from acts or omissions to act occurring before or after its adoption. The provisions of this Section 10.02 shall be deemed to be a contract between the Company and each person entitled to indemnification under this Section 10.02 (or legal representative thereof) who serves in such capacity at any time while this Section 10.02 and the relevant provisions of applicable Law, if any, are in effect, and any amendment, modification or repeal hereof shall not affect any rights or obligations then existing with respect to any state of facts or any action, suit or proceeding then or theretofore existing, or any action, suit or proceeding thereafter brought or threatened based in whole or in part on any such state of facts. If any provision of this Section 10.02 shall be found to be invalid or limited in application by reason of any law or regulation, it shall not affect the validity of the remaining provisions hereof. The rights of indemnification provided in this Section 10.02 shall neither be exclusive of, nor be deemed in limitation of, any rights to which any person may otherwise be or become entitled or permitted by contract, this Agreement or as a matter of law, both as to actions in such person’s official capacity and actions in any other capacity, it being the policy of the Company that indemnification of any person whom the Company is obligated to indemnify pursuant to Section 10.02(a) shall be made to the fullest extent permitted by law.

(f) ARTICLE EIGHT of the Pubco Charter shall apply mutatis mutandis to this Agreement as if it were incorporated herein.

(g)

(i) For purposes of this Article X, (x) “Affiliate” shall mean (A) in respect of a member of the Board of Directors, any Person that, directly or indirectly, is controlled by such member of the Board of Directors (other than the Company and any entity that is controlled by the Company), (B) in respect of any of the Stockholder Parties, a Person that, directly or indirectly, is controlled by any of the Stockholder Parties, controls any of the Stockholder Parties or is under common control with any of the Stockholder Parties and shall include any principal, member, director, partner, stockholder, officer, employee or other representative of any of the foregoing (other than the Company and any entity that is controlled by the Company) and (C) in respect of the Company, any Person that, directly or indirectly, is controlled by the Company and (y) “Person” shall mean any

G-38

individual, corporation, general or limited partnership, limited liability company, joint venture, trust, association or any other entity.

(ii) For the purposes of this Article, “control,” including the terms “controlling,” “controlled by” and “under common control with,” means the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person, whether through the ownership of voting stock, by contract, or otherwise. A person who is the owner of 20% or more of the outstanding voting stock of a corporation, partnership, unincorporated association or other entity shall be presumed to have control of such entity, in the absence of proof by a preponderance of the evidence to the contrary. Notwithstanding the foregoing, a presumption of control shall not apply where such person holds voting stock, in good faith and not for the purpose of circumventing this Section (F) of Article X, as an agent, bank, broker, nominee, custodian or trustee for one or more owners who do not individually or as a group have control of such entity.

(iii) For purposes of this Section 10.02, references to “fines” shall include any excise taxes assessed on a person with respect to an employee benefit plan.

(iv) This Section 10.02 shall not limit the right of the Company, to the extent and in the manner permitted by law, to indemnify and to advance expenses to, and purchase and maintain insurance on behalf of, persons other than persons described in Section 10.02(a).

(iv) to determine the terms and conditions, not inconsistent with the terms of the Plan, of each Award granted hereunder, including, but not limited to, (A) the restrictions applicable to Awards and the conditions under which restrictions applicable to such Awards shall lapse, (B) the Performance Goals and performance periods applicable to Awards, if any, (C) the Exercise Price of each Award, (D) the vesting schedule applicable to each Award, (E) any confidentiality or restrictive covenant provisions applicable to the Award, and (F) subject to the requirements of Code Section 409A (to the extent applicable), any amendments to the terms and conditions of outstanding Awards, including, but not limited to, extending the exercise period of such Awards and accelerating the vesting schedule of such Awards;

(v) to determine the terms and conditions, not inconsistent with the terms of the Plan, which shall govern all Award Agreements evidencing Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units or Other Share-Based Awards, Other Cash-Based Awards or any combination of the foregoing granted hereunder;

(vi) to determine Fair Market Value;

(vii) to determine the duration and purpose of leaves of absence which may be granted to a Participant without constituting termination of the Participant’s employment for purposes of Awards granted under the Plan;

(viii) to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable;

(ix) to reconcile any inconsistency in, correct any defect in and/or supply any omission in the Plan, any Award Agreement or other instrument or agreement relating to the Plan or an Award granted under the Plan; and

H-7

(x) to construe and interpret the terms and provisions of the Plan and any Award issued under the Plan (and any Award Agreement relating thereto), and to otherwise supervise the administration of the Plan and to exercise all powers and authorities either specifically granted under the Plan or necessary and advisable in the administration of the Plan.

(c) All decisions made by the Administrator pursuant to the provisions of the Plan shall be final, conclusive and binding on all persons, including the Company and the Participants. No member of the Board or the Committee, or any officer or employee of the Company or any Subsidiary thereof acting on behalf of the Board or the Committee, shall be personally liable for any action, omission, determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Board or the Committee and each and any officer or employee of the Company and of any Subsidiary thereof acting on their behalf shall, to the maximum extent permitted by law, be fully indemnified and protected by the Company in respect of any such action, omission, determination or interpretation.

Section 4. Shares Reserved for Issuance Under the Plan and Limitations on Awards.

(a) Subject to adjustment in accordance with Section 5 of the Plan, the Administrator is authorized to deliver with respect to Awards granted under the Plan an aggregate of [●] shares of Common Stock.

(b) Notwithstanding anything herein to the contrary, the maximum number of Shares subject to Awards granted during any fiscal year to any Non-Employee Director, taken together with any cash fees paid to such Non-Employee Director during the fiscal year with respect to such Director’s service as a Non-Employee Director, shall not exceed $900,000 (calculating the value of any such Awards based on the grant date Fair Market Value of such Awards for financial reporting purposes); provided, that any Awards granted under the Plan or other compensation received by a Non-Employee Director related to the settlement, conversion or substitution of the Non-Employee Director’s award(s) under the Prior Plan shall not count against such limit.

(c) Shares issued under the Plan may, in whole or in part, be authorized but unissued Shares or Shares that shall have been or may be reacquired by the Company in the open market, in private transactions or otherwise. Any shares of Common Stock subject to an Award under the Plan that, after the Effective Date, are forfeited, canceled, settled or otherwise terminated without a distribution of Shares to a Participant will thereafter be deemed to be available for Awards with respect to shares of Common Stock. In applying the immediately preceding sentence, if (i) Shares otherwise issuable or issued in respect of, or as part of, any Award are withheld to cover taxes or any applicable Exercise Price, such Shares shall be treated as having been issued under the Plan and shall not be available for issuance under the Plan, and (ii) any Share-settled Stock Appreciation Rights or Options are exercised, the aggregate number of Shares subject to such Stock Appreciation Rights or Options shall be deemed issued under the Plan and shall not be available for issuance under the Plan. In addition, Shares (x) tendered to exercise outstanding Options or other Awards, (y) withheld to cover applicable taxes on any Awards or (z) repurchased on the open market using Exercise Price proceeds shall not be available for issuance under the Plan. For the avoidance of doubt, (A) Shares underlying Awards that are subject to the achievement of performance goals shall be counted against the Share reserve based on the target value of such Awards unless and until such time as such Awards become vested and settled in Shares, and (B) Awards that, pursuant to their terms, may be settled only in cash shall not count against the Share reserve set forth in Section 4(a).

(d) Substitute Awards shall not reduce the Shares authorized for grant under the Plan. In the event that a company acquired by the Company or any Affiliate or with which the Company or any Affiliate combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the Shares authorized for grant under the Plan; provided, that Awards using such available Shares shall

H-8

not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not employed by or providing services to the Company or its Affiliates immediately prior to such acquisition or combination.

(e) In the event that the Company or an Affiliate thereof consummates a transaction described in Code Section 424(a) (e.g., the acquisition of property or stock from an unrelated corporation), persons who become Employees or Directors in account of such transaction may be granted Substitute Awards in substitution for awards granted by their former employer, and any such substitute Options or Stock Appreciation Rights may be granted with an Exercise Price less than the Fair Market Value of a Share on the grant date thereof; provided, however, the grant of such substitute Option or Stock Appreciation Right shall not constitute a “modification” as defined in Code Section 424(h)(3) and the applicable Treasury regulations.

Section 5. Equitable Adjustments.

In the event of any Change in Capitalization, including, without limitation, a Change in Control, an equitable substitution or proportionate adjustment shall be made, in each case, as may be determined by the Administrator, in its sole discretion, in (a) the aggregate number of Shares reserved for issuance under the Plan, (b) the kind, number and Exercise Price subject to outstanding Options and Stock Appreciation Rights granted under the Plan; provided, however, that any such substitution or adjustment with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A, and (c) the kind, number and purchase price of Shares subject to outstanding Restricted Shares or Other Share-Based Awards granted under the Plan, in each case as may be determined by the Administrator, in its sole discretion; provided, however, that any fractional Shares resulting from the adjustment shall be eliminated. Such other equitable substitutions or adjustments shall be made as may be determined by the Administrator, in its sole discretion. Without limiting the generality of the foregoing, in connection with a Change in Capitalization, the Administrator may provide, in its sole discretion, for the cancellation of any outstanding Award granted hereunder (i) in exchange for payment in cash or other property having an aggregate Fair Market Value of the Shares covered by such Award, reduced by the aggregate Exercise Price or purchase price thereof, if any, and (ii) with respect to any Awards for which the Exercise Price or purchase price per share of Common Stock is greater than or equal to the then current Fair Market Value per share of Common Stock, for no consideration. Notwithstanding anything contained in the Plan to the contrary, any adjustment with respect to an Incentive Stock Option due to an adjustment or substitution described in this Section 5 shall comply with the rules of Code Section 424(a), and in no event shall any adjustment be made which would render any Incentive Stock Option granted hereunder to be disqualified as an incentive stock option for purposes of Code Section 422. The Administrator’s determinations pursuant to this Section 5 shall be final, binding and conclusive.

Section 6. Eligibility.

The Participants under the Plan shall be selected from time to time by the Administrator, in its sole discretion, from among Eligible Recipients.

Section 7. Options.

(a) General. The Administrator may, in its sole discretion, grant Options to Participants. Solely with respect to Participants who are Employees, the Administrator may grant Incentive Stock Options, Nonqualified Stock Options or a combination of both. With respect to all other Participants, the Administrator may grant only Nonqualified Stock Options. Each Participant who is granted an Option shall enter into an Award Agreement with the Company, containing such terms and conditions as the Administrator shall determine, in its sole discretion, which Award Agreement shall specify whether the Option is an Incentive Stock Option or a Nonqualified Stock Option and shall set forth, among other things, the Exercise Price of the Option, the term of the Option and provisions regarding exercisability of the Option granted thereunder. The provisions of each Option need not be the same with respect to each Participant. More than one Option may be granted to the same

H-9

Participant and be outstanding concurrently hereunder. Options granted under the Plan shall be subject to the terms and conditions set forth in this Section 7 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable and set forth in the applicable Award Agreement. The prospective recipient of an Option shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(b) Limits on Incentive Stock Options. If the Administrator grants Incentive Stock Options, then to the extent that the aggregate fair market value of Shares with respect to which Incentive Stock Options are exercisable for the first time by any individual during any calendar year (under all plans of the Company) exceeds $100,000, such Options will be treated as Nonqualified Stock Options to the extent required by Code Section 422. Subject to Section 5, the maximum number of shares that may be issued pursuant to Options intended to be Incentive Stock Options is [●] Shares and, for the avoidance of doubt, such share limit shall not be subject to the annual adjustment provided in Section 4(a).

(c) Exercise Price. The Exercise Price of Shares purchasable under an Option shall be determined by the Administrator in its sole discretion at the time of grant; provided, however, that (i) in no event shall the Exercise Price of an Option be less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant, and (ii) no Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) shall have an Exercise Price per Share less than one-hundred ten percent (110%) of the Fair Market Value of a Share on such date.

(d) Option Term. The maximum term of each Option shall be fixed by the Administrator, but in no event shall (i) an Option be exercisable more than ten (10) years after the date such Option is granted, and (ii) an Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) be exercisable more than five (5) years after the date such Option is granted. Each Option’s term is subject to earlier expiration pursuant to the applicable provisions in the Plan and the Award Agreement. Notwithstanding the foregoing, the Administrator shall have the authority to accelerate the exercisability of any outstanding Option at such time and under such circumstances as the Administrator, in its sole discretion, deems appropriate. Notwithstanding any contrary provision in this Plan (including, without limitation, Section 7(h)), if, on the date an outstanding Option would expire, the exercise of the Option, including by a “net exercise” or “cashless” exercise, would violate applicable securities laws or any insider trading policy maintained by the Company from time to time, the expiration date applicable to the Option will be extended, except to the extent such extension would violate Code Section 409A, to a date that is thirty (30) calendar days after the date the exercise of the Option would no longer violate applicable securities laws or any such insider trading policy.

(e) Exercisability. Each Option shall be exercisable at such time or times and subject to such terms and conditions, including the attainment of pre-established Performance Goals, as shall be determined by the Administrator in the applicable Award Agreement. The Administrator may also provide that any Option shall be exercisable only in installments, and the Administrator may waive such installment exercise provisions at any time, in whole or in part, based on such factors as the Administrator may determine in its sole discretion. Notwithstanding anything to the contrary contained herein, an Option may not be exercised for a fraction of a share.

(f) Method of Exercise. Options may be exercised in whole or in part by giving written notice of exercise to the Company specifying the number of Shares to be purchased, accompanied by payment in full of the aggregate Exercise Price of the Shares so purchased in cash or its equivalent, as determined by the Administrator. As determined by the Administrator, in its sole discretion, with respect to any Option or category of Options, payment in whole or in part may also be made (i) by means of consideration received under any cashless exercise procedure approved by the Administrator (including the withholding of Shares otherwise issuable upon exercise),

H-10

(ii) in the form of unrestricted Shares already owned by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the Shares as to which such Option shall be exercised, (iii) any other form of consideration approved by the Administrator and permitted by applicable law, or (iv) any combination of the foregoing. In determining which methods a Participant may utilize to pay the Exercise Price, the Administrator may consider such factors as it determines are appropriate; provided, however, that with respect to Incentive Stock Options, all such discretionary determinations shall be made by the Administrator at the time of grant and specified in the Award Agreement.

(g) Rights as Stockholder. A Participant shall have no rights to dividends or any other rights of a stockholder with respect to the Shares subject to an Option until the Participant has given written notice of the exercise thereof, has paid in full for such Shares and has satisfied the requirements of Section 16 of the Plan.

(h) Termination of Employment or Service. Unless the applicable Award Agreement provides otherwise, in the event that the employment or service of a Participant with the Company and all Affiliates thereof shall terminate, the following terms and conditions shall apply:

(i) In the event of the termination of a Participant’s employment or service by the Company without Cause or due to a resignation by the Participant for any reason, (A) Options granted to such Participant, to the extent that they are exercisable at the time of such termination, shall remain exercisable until the date that is ninety (90) days after such termination (with such period being extended to one (1) year after the date of such termination in the event of the Participant’s death during such ninety (90) day period), on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(ii) In the event of the termination of a Participant’s employment or service as a result of the Participant’s Disability or death, (A) Options granted to such Participant, to the extent that they were exercisable at the time of such termination, shall remain exercisable until the date that is one (1) year after such termination, on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(iii) In the event of the termination of a Participant’s employment or service for Cause, all outstanding Options granted to such Participant shall expire at the commencement of business on the date of such termination.

(iv) For purposes of determining which Options are exercisable upon termination of employment or service for purposes of this Section 7(h), Options that are not exercisable solely due to a blackout period shall be considered exercisable.

(v) Notwithstanding anything herein to the contrary, an Incentive Stock Option may not be exercised more than three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability. In the event that an Option is exercisable following the date that is three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability, such Option shall be deemed to be a Nonqualified Stock Option.

(i) Other Change in Employment Status. An Option may be affected, both with regard to vesting schedule and termination, by leaves of absence, changes from full-time to part-time employment, partial disability or other changes in the employment status or service of a Participant, as evidenced in a Participant’s Award Agreement.

(j) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Options shall be subject to Section 12 of the Plan.

(k) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable

H-11

Option outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. In the sole discretion of the Administrator, payment of the exercise price of any such Option shall be made pursuant to Section 7(f)(i) or (ii), and the Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 7(k) shall not apply to an Option if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Option with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 7(k).

Section 8. Stock Appreciation Rights.

(a) General. Stock Appreciation Rights may be granted either alone (“Free Standing Rights”) or in conjunction with all or part of any Option granted under the Plan (“Related Rights”). Any Related Right that relates to a Nonqualified Stock Option may be granted at the same time the Option is granted or at any time thereafter, but before the exercise or expiration of the Option. Any Related Right that relates to an Incentive Stock Option must be granted at the same time the Incentive Stock Option is granted. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Stock Appreciation Rights shall be made, the number of Shares to be awarded, the price per Share, and all other conditions of Stock Appreciation Rights. Notwithstanding the foregoing, no Related Right may be granted for more Shares than are subject to the Option to which it relates and any Stock Appreciation Right must be granted with an Exercise Price not less than the Fair Market Value of a Share on the date of grant. The provisions of Stock Appreciation Rights need not be the same with respect to each Participant. Stock Appreciation Rights granted under the Plan shall be subject to the following terms and conditions set forth in this Section 8 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable, as set forth in the applicable Award Agreement.

(b) Awards; Rights as Stockholder. The prospective recipient of a Stock Appreciation Right shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Participants who are granted Stock Appreciation Rights shall have no rights as stockholders of the Company with respect to the grant or exercise of such rights.

(c) Exercisability.

(i) Stock Appreciation Rights that are Free Standing Rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Stock Appreciation Rights that are Related Rights shall be exercisable only at such time or times and to the extent that the Options to which they relate shall be exercisable in accordance with the provisions of Section 7 above and this Section 8 of the Plan.

(d) Payment Upon Exercise.

(i) Upon the exercise of a Free Standing Right, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the price per share specified in the Free Standing Right multiplied by the number of Shares in respect of which the Free Standing Right is being exercised.

(ii) A Related Right may be exercised by a Participant by surrendering the applicable portion of the related Option. Upon such exercise and surrender, the Participant shall be entitled to receive up to, but not more than, that number of Shares, determined using the Fair Market Value, equal in value to the excess of

H-12

the Fair Market Value as of the date of exercise over the Exercise Price specified in the related Option multiplied by the number of Shares in respect of which the Related Right is being exercised. Options which have been so surrendered, in whole or in part, shall no longer be exercisable to the extent the Related Rights have been so exercised.

(iii) Notwithstanding the foregoing, the Administrator may determine to settle the exercise of a Stock Appreciation Right in cash (or in any combination of Shares and cash).

(e) Termination of Employment or Service.

(i) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Free Standing Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii) Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Related Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as set forth in the related Options.

(f) Term.

(i) The term of each Free Standing Right shall be fixed by the Administrator, but no Free Standing Right shall be exercisable more than ten (10) years after the date such right is granted.

(ii) The term of each Related Right shall be the term of the Option to which it relates, but no Related Right shall be exercisable more than ten (10) years after the date such right is granted.

(g) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Stock Appreciation Rights shall be subject to Section 12 of the Plan.

(h) Automatic Exercise. Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Stock Appreciation Right outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. The Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 8(h) shall not apply to a Stock Appreciation Right if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Stock Appreciation Right with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 8(h).

Section 9. Restricted Shares.

(a) General. Each Award of Restricted Shares granted under the Plan shall be evidenced by an Award Agreement. Restricted Shares may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Shares shall be made; the number of Shares to be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares; the Restricted Period, if any, applicable to Restricted Shares; the Performance Goals (if any) applicable to Restricted Shares; and all other conditions of the Restricted Shares. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Shares in accordance with the terms of the grant. The terms and conditions applicable to the Restricted Shares need not be the same with respect to each Participant.

H-13

(b) Awards and Certificates. The prospective recipient of Restricted Shares shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Except as otherwise provided in herein, (i) each Participant who is granted an Award of Restricted Shares may, in the Company’s sole discretion, be issued a stock certificate in respect of such Restricted Shares; and (ii) any such certificate so issued shall be registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to any such Award. The Company may require that the stock certificates, if any, evidencing Restricted Shares granted hereunder be held in the custody of the Company until the restrictions thereon shall have lapsed, and that, as a condition of any award of Restricted Shares, the Participant shall have delivered a stock power, endorsed in blank, relating to the Shares covered by such Award. Notwithstanding anything in the Plan to the contrary, any Restricted Shares (whether before or after any vesting conditions have been satisfied) may, in the Company’s sole discretion, be issued in uncertificated form pursuant to the customary arrangements for issuing shares in such form.

(c) Restrictions and Conditions. The Restricted Shares granted pursuant to this Section 9 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or thereafter:

(i) The Restricted Shares shall be subject to the restrictions on transferability set forth in the Award Agreement and in the Plan.

(ii) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(iii) Subject to this Section 9(c)(ii), the Participant shall generally have the rights of a stockholder of the Company with respect to Restricted Shares during the Restricted Period. In the Administrator’s discretion and as provided in the applicable Award Agreement, a Participant may be entitled to dividends or dividend equivalents on an Award of Restricted Shares, which will be payable in accordance with the terms of such grant as determined by the Administrator in accordance with Section 18 of the Plan. Certificates for unrestricted Shares may, in the Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without forfeiture in respect of such Restricted Shares, except as the Administrator, in its sole discretion, shall otherwise determine.

(iv) The rights of Participants granted Restricted Shares upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Shares shall be subject to Section 12 of the Plan.

Section 10. Restricted Stock Units.

(a) General. Restricted Stock Units may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Stock Units shall be made; the number of Restricted Stock Units to be awarded; the Restricted Period, if any, applicable to Restricted Stock Units; the Performance Goals (if any) applicable to Restricted Stock Units; and all other conditions of the Restricted Stock Units. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Stock Units in accordance with the terms of the grant. The provisions of Restricted Stock Units need not be the same with respect to each Participant.

H-14

(b) Award Agreement. The prospective recipient of Restricted Stock Units shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Restrictions and Conditions. The Restricted Stock Units granted pursuant to this Section 10 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or, subject to Code Section 409A, thereafter:

(i) The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(ii) Participants holding Restricted Stock Units shall have no voting rights. A Restricted Stock Unit may, at the Administrator’s discretion, carry with it a right to dividend equivalents, subject to Section 18 of the Plan. Such right would entitle the holder to be credited with an amount equal to all cash dividends paid on one Share while the Restricted Stock Unit is outstanding. The Administrator, in its discretion, may grant dividend equivalents from the date of grant or only after a Restricted Stock Unit is vested.

(iii) The rights of Participants granted Restricted Stock Units upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d) Settlement of Restricted Stock Units. Settlement of vested Restricted Stock Units shall be made to Participants in the form of Shares, unless the Administrator, in its sole discretion, provides for the payment of the Restricted Stock Units in cash (or partly in cash and partly in Shares) equal to the value of the Shares that would otherwise be distributed to the Participant.

(e) Change in Control. Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Stock Units shall be subject to Section 12 of the Plan.

Section 11. Other Share-Based or Cash-Based Awards.

(a) The Administrator is authorized to grant Awards to Participants in the form of Other Share-Based Awards or Other Cash-Based Awards, as deemed by the Administrator to be consistent with the purposes of the Plan and as evidenced by an Award Agreement. The Administrator shall determine the terms and conditions of such Awards, consistent with the terms of the Plan, at the date of grant or thereafter, including any Performance Goals and performance periods. Shares or other securities or property delivered pursuant to an Award in the nature of a purchase right granted under this Section 11 shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, Shares, other Awards, notes or other property, as the Administrator shall determine, subject to any required corporate action.

(b) The prospective recipient of an Other Share-Based Award or Other Cash-Based Award shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c) Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Other Share-Based Awards and Other Cash-Based Awards shall be subject to Section 12 of the Plan.

H-15

Section 12. Change in Control.

The Administrator may provide in the applicable Award Agreement that an Award will vest on an accelerated basis upon the Participant’s termination of employment or service in connection with a Change in Control or upon the occurrence of any other event that the Administrator may set forth in the Award Agreement. If the Company is a party to an agreement that is reasonably likely to result in a Change in Control, such agreement may provide for: (i) the continuation of any Award by the Company, if the Company is the surviving corporation; (ii) the assumption of any Award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any Award, provided, however, that any such substitution with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A; or (iv) settlement of any Award for the Change in Control Price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the Change in Control Price or if the Administrator determines that Award cannot reasonably become vested pursuant to its terms, such Award shall terminate and be canceled without consideration. To the extent that Restricted Shares, Restricted Stock Units or other Awards settle in Shares in accordance with their terms upon a Change in Control, such Shares shall be entitled to receive as a result of the Change in Control transaction the same consideration as the Shares held by stockholders of the Company as a result of the Change in Control transaction. For purposes of this Section 12, “Change in Control Price” shall mean (A) the price per Share paid to stockholders of the Company in the Change in Control transaction, or (B) the Fair Market Value of a Share upon a Change in Control, as determined by the Administrator. To the extent that the consideration paid in any such Change in Control transaction consists all or in part of securities or other non-cash consideration, the value of such securities or other non-cash consideration shall be determined in good faith by the Administrator.

Section 13. Amendment and Termination.

(a) The Board or the Committee may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would adversely alter or impair the rights of a Participant under any Award theretofore granted without such Participant’s prior written consent.

(b) Notwithstanding the foregoing, (i) approval of the Company’s stockholders shall be obtained for any amendment that would require such approval in order to satisfy the requirements of Code Section 422, if applicable, any rules of the stock exchange on which the Shares are traded or other applicable law, and (ii) without stockholder approval to the extent required by the rules of any applicable national securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, except as otherwise permitted under Section 5 of the Plan, (A) no amendment or modification may reduce the Exercise Price of any Option or Stock Appreciation Right, (B) the Administrator may not cancel any outstanding Option or Stock Appreciation Right and replace it with a new Option or Stock Appreciation Right, another Award or cash and (C) the Administrator may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer quotation system.

(c) Subject to the terms and conditions of the Plan and Code Section 409A, the Administrator may modify, extend or renew outstanding Awards under the Plan, or accept the surrender of outstanding Awards (to the extent not already exercised) and grant new Awards in substitution of them (to the extent not already exercised).

(d) Notwithstanding the foregoing, no alteration, modification or termination of an Award will, without the prior written consent of the Participant, adversely alter or impair any rights or obligations under any Award already granted under the Plan.

Section 14. Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. Neither the Company, the Board nor the Committee shall be required to establish any special or separate fund or to segregate any assets to

H-16

assure the performance of its obligations under the Plan. With respect to any payments not yet made or Shares not yet transferred to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general unsecured creditor of the Company.

Section 15. Deferrals of Payment.

To the extent permitted by applicable law, the Administrator, in its sole discretion, may determine that the delivery of Shares or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award, shall be deferred. The Administrator may also, in its sole discretion, establish one or more programs under the Plan to permit selected Participants the opportunity to elect to defer receipt of any such consideration, including any applicable election procedures, the timing of such elections, the mechanisms for payments of amounts, shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program. Deferrals by Participants (or deferred settlement or payment required by the Administrator) shall be made in accordance with Code Section 409A, if applicable, and any other applicable law.

Section 16. Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for federal, state and/or local income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind, domestic or foreign, required by law or regulation to be withheld with respect to the Award. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award granted hereunder, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any federal, state and local withholding tax requirements related thereto. Whenever Shares are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related federal, state and local taxes, domestic or foreign, to be withheld and applied to the tax obligations. With the approval of the Administrator, a Participant may satisfy the foregoing requirement by electing to have the Company withhold from delivery of Shares or by delivering already owned unrestricted Shares, in each case, having a value equal to the amount required to be withheld or other greater amount not exceeding the maximum statutory rate required to be collected on the transaction under applicable law, as applicable to the Participant, if such other greater amount would not, as determined by the Administrator, result in adverse financial accounting treatment (including in connection with the effectiveness of FASB Accounting Standards Update 2016-09). Such Shares shall be valued at their Fair Market Value on the date of which the amount of tax to be withheld is determined. Fractional share amounts shall be settled in cash. Such an election may be made with respect to all or any portion of the Shares to be delivered pursuant to an Award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Option or other Award (including by a “net exercise” or broker assisted “cashless” exercise procedure approved by the Administrator).

Section 17. Certain Forfeitures.

The Administrator may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon the occurrence of certain events, in addition to the applicable vesting conditions of an Award. Such events may include, without limitation, breach of any non-competition, non-solicitation, confidentiality, or other restrictive covenants that are contained in an Award Agreement or that are otherwise applicable to the Participant, a termination of the Participant’s employment for Cause, or other conduct by the Participant that is detrimental to the business or reputation of the Company and its Subsidiaries and/or its Affiliates.

H-17

Section 18. Dividends; Dividend Equivalents.

Notwithstanding anything in this Plan to the contrary, to the extent that an Award contains a right to receive dividends or dividend equivalents while such Award remains unvested, such dividends or dividend equivalents will be accumulated and paid once and to the extent that the underlying Award vests, and forfeited to the extent the underlying Award is forfeited.

Section 19. Non-United States Employees.

Without amending the Plan, the Administrator may grant Awards to eligible persons residing in non-United States jurisdictions on such terms and conditions different from those specified in the Plan, including the terms of any award agreement or plan, adopted by the Company or any Subsidiary thereof to comply with, or take advantage of favorable tax or other treatment available under, the laws of any non-United States jurisdiction, as may in the judgment of the Administrator be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in furtherance of such purposes the Administrator may make such modifications, amendments, procedures, sub-plans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Subsidiaries operates or has employees.

Section 20. Transfer of Awards.

No purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator, and other than by will or by the laws of descent and distribution. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio, and shall not create any obligation or liability of the Company, and any person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a holder of such Shares. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative. Under no circumstances will a Participant be permitted to transfer an Option or Stock Appreciation Right to a third-party financial institution without prior stockholder approval.

Section 21. Continued Employment.

The adoption of the Plan shall not confer upon any Eligible Recipient any right to continued employment or service with the Company or an Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or an Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time.

Section 22. Effective Date.

The Plan will be effective as of the date of consummation of the transactions contemplated by that certain business combination agreement, dated as of July 15, 2021, by and among Altimar Acquisition Corp. II, a Cayman Islands corporation, Fathom HoldCo LLC, a Delaware limited liability company and such other parties to the agreement as set forth therein and as subject to approval by the Company’s stockholders (the “Effective Date”). The Plan will be unlimited in duration and, in the event of Plan termination, will remain in effect as long as any Shares awarded under it are outstanding and not fully vested; provided, however, that no Awards will be made under the Plan on or after the tenth anniversary of the Effective Date.

H-18

Section 23. Code Section 409A.

The intent of the parties is that payments and benefits under the Plan be either exempt from Code Section 409A or comply with Code Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered consistent with such intent. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Code Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required in order to avoid accelerated taxation and/or tax penalties under Code Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon a “separation from service” to a Participant who is a “specified employee” shall be paid on the first business day after the date that is six (6) months following the Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, for purposes of the Plan, each amount to be paid or benefit to be provided to the Participant pursuant to the Plan, which constitute deferred compensation subject to Code Section 409A, shall be construed as a separate identified payment for purposes of Code Section 409A. Nothing contained in the Plan or an Award Agreement shall be construed as a guarantee of any particular tax effect with respect to an Award. The Company does not guarantee that any Awards provided under the Plan will be exempt from or in compliance with the provisions of Code Section 409A, and in no event will the Company be liable for any or all portion of any taxes, penalties, interest or other expenses that may be incurred by a Participant on account of any Award being subject to, but not in compliance with, Code Section 409A.

Section 24. Compliance with Laws.

(a) The obligation of the Company to settle Awards in Shares or other consideration shall be subject to (i) all applicable laws, rules, and regulations, (ii) such approvals as may be required by governmental agencies or the applicable national securities exchange on which the Shares may be admitted, and (iii) policies maintained by the Company from time to time in order to comply with applicable laws, rules, regulations and corporate governance requirements, including, without limitation, with respect to insider trading restrictions. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any Shares pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such Shares may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the Shares to be offered or sold under the Plan. The Administrator shall have the authority to provide that all Shares or other securities of the Company issued under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted and any other applicable federal, state, local or non-U.S. laws, rules, regulations and other requirements, and the Administrator may cause a legend or legends to be put on certificates representing Shares or other securities of the Company issued under the Plan to make appropriate reference to such restrictions or may cause such Shares or other securities of the Company issued under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it, in its sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

(b) The Administrator may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of Shares from the public markets, the Company’s issuance of Shares to the Participant, the Participant’s acquisition of Shares from the Company and/or the Participant’s sale of Shares to the public

H-19

markets, illegal, impracticable or inadvisable. If the Administrator determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply with Code Section 409A, (i) pay to the Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the Shares subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the Shares would have been vested or issued, as applicable), over (B) the aggregate Exercise Price (in the case of an Option or Stock Appreciation Right) or any amount payable as a condition of issuance of Shares (in the case of any other Award), and such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof, or (ii) in the case of Restricted Shares, Restricted Stock Units or Other Share-Based Awards, provide the Participant with a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Shares, Restricted Stock Units or Other Share-Based Awards, or the underlying Shares in respect thereof.

Section 25. No Interference.

The existence of the Plan, any Award Agreement, and the Awards granted hereunder shall not affect or restrict in any way the right or power of the Company, the Board, the Committee, or the stockholders of the Company to make or authorize any adjustment, recapitalization, reorganization, or other change in the Company’s capital structure or its business, any merger or consolidation of the Company, any issue of stock or of options, warrants, or rights to purchase stock or of bonds, debentures, or preferred or prior preference stocks whose rights are superior to or affect the Common Stock or the rights thereof or that are convertible into or exchangeable for Common Stock, or the dissolution or liquidation of the Company or any Affiliate, or any sale or transfer of all or any part of their assets or business, or any other corporate act or proceeding, whether of a similar character or otherwise.

Section 26. Erroneously Awarded Compensation; Clawback.

The Plan and all Awards issued hereunder shall be subject to any compensation recovery and/or recoupment policy adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or to comport with good corporate governance practices, including on a retroactive basis, as such policies may be amended from time to time. Notwithstanding anything to the contrary contained herein, the Administrator also may cancel an Award if the Participant, without the consent of the Company, (a) has engaged in or engages in activity that is in conflict with or adverse to the interests of the Company or any Affiliate while employed by or providing services to the Company or any Affiliate, including fraud or conduct contributing to any financial restatements or irregularities or (b) violates a non-competition, non-solicitation, non-disparagement or non-disclosure covenant or agreement with the Company or any Affiliate, as determined by the Administrator, or if the Participant’s employment or service is terminated for Cause. The Administrator may also provide in an Award Agreement that in any such event the Participant will forfeit any compensation, gain or other value realized thereafter on the vesting, exercise or settlement of such Award, the sale or other transfer of such Award, or the sale of shares of Common Stock acquired in respect of such Award, and must promptly repay such amounts to the Company. The Administrator may also provide in an Award Agreement that if the Participant receives any amount in excess of what the Participant should have received under the terms of the Award for any reason (including without limitation by reason of a financial restatement, mistake in calculations or other administrative error), all as determined by the Administrator, then the Participant shall be required to promptly repay any such excess amount to the Company. In addition, the Company shall retain the right to bring an action at equity or law to enjoin the Participant’s activity and recover damages resulting from such activity.

Section 27. Whistleblower Acknowledgements.

Notwithstanding anything to the contrary herein, nothing in this Plan or any Award Agreement will (a) prohibit a Participant from making reports of possible violations of federal law or regulation to any

H-20

governmental agency or entity in accordance with the provisions of and rules promulgated under Section 21F of the Exchange Act or Section 806 of the Sarbanes-Oxley Act of 2002, or of any other whistleblower protection provisions of federal law or regulation, or (b) require prior approval by the Company or any of its Affiliates of any reporting described in clause (a).

Section 28. Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law of such state.

Section 29. Plan Document Controls.

The Plan and each Award Agreement together constitute the entire agreement with respect to the subject matter hereof and thereof; provided, that in the event of any inconsistency between the Plan and such Award Agreement, the terms and conditions of the Plan shall control.

Offering Periods will expire on the earliest to occur of (i) the completion of the purchase of Shares on the last Exercise Date occurring within twenty-seven (27) months of the applicable Enrollment Date on which the option to purchase Shares was granted, or (ii) such shorter period as may be established by the Administrator from time to time, in its discretion and on a uniform and nondiscriminatory basis, prior to an Enrollment Date for all options to be granted on such Enrollment Date.

5.    Participation. An Eligible Employee may participate in the Plan by (i) submitting to the Company’s stock administration office (or its designee) a properly completed subscription agreement authorizing Contributions in the form provided by the Administrator for such purpose or (ii) following an electronic or other enrollment procedure determined by the Administrator, in either case on or before a date determined by the Administrator prior to an applicable Enrollment Date.

6.    Contributions.

(a)    At the time a Participant enrolls in the Plan pursuant to Section 5, he or she will elect to have Contributions (in the form of payroll deductions or otherwise, to the extent permitted by the Administrator) made on each pay day during the Offering Period in an amount that will be subject to such limits as the Administrator may establish from time to time, in its discretion and on a uniform and nondiscriminatory basis, for all options to be granted on any Enrollment Date. The Administrator, in its sole discretion, may permit all Participants in a specified Offering to contribute amounts to the Plan through payment by cash, check or other means set forth in the subscription agreement prior to each Exercise Date of each Purchase Period. A Participant’s subscription agreement will remain in effect for successive Offering Periods unless terminated as provided in Section 10 hereof.

I-5

(b)    In the event Contributions are made in the form of payroll deductions, such payroll deductions for a Participant will commence on the first pay day following the Enrollment Date and will end on the last pay day on or prior to the last Exercise Date of such Offering Period to which such authorization is applicable, unless sooner terminated by the Participant as provided in Section 10 hereof.

(c)    All Contributions made for a Participant will be credited to his or her account under the Plan and Contributions will be made in whole percentages of his or her Compensation only. A Participant may not make any additional payments into such account.

(d)    A Participant may discontinue his or her participation in the Plan as provided under Section 10. Except as may be permitted by the Administrator, as determined in its sole discretion, a Participant may not change the rate of his or her Contributions during an Offering Period.

(e)    Notwithstanding the foregoing, to the extent necessary to comply with Section 423(b)(8) of the Code and Section 3(c), a Participant’s Contributions may be decreased to zero percent (0%) at any time during a Purchase Period. Subject to Section 423(b)(8) of the Code and Section 3(c) hereof, Contributions will recommence at the rate originally elected by the Participant effective as of the beginning of the first Purchase Period scheduled to end in the following calendar year, unless terminated by the Participant as provided in Section 10.

(f)    Notwithstanding any provisions to the contrary in the Plan, the Administrator may allow Participants to participate in the Plan via cash contributions instead of payroll deductions if (i) payroll deductions are not permitted under applicable local law, or (ii) the Administrator determines that cash contributions are permissible under Section 423 of the Code.

(g)    At the time the option is exercised, in whole or in part, or at the time some or all of the Common Stock issued under the Plan is disposed of (or any other time that a taxable event related to the Plan occurs), the Participant must make adequate provision for the Company’s or Employer’s federal, state, local or any other tax liability payable to any authority including taxes imposed by jurisdictions outside of the U.S., national insurance, social security or other tax withholding obligations, if any, which arise upon the exercise of the option or the disposition of the Common Stock (or any other time that a taxable event related to the Plan occurs). At any time, the Company or the Employer may, but will not be obligated to, withhold from the Participant’s compensation the amount necessary for the Company or the Employer to meet applicable withholding obligations, including any withholding required to make available to the Company or the Employer any tax deductions or benefits attributable to sale or early disposition of Common Stock by the Eligible Employee. In addition, the Company or the Employer may, but will not be obligated to, withhold from the proceeds of the sale of Common Stock or any other method of withholding the Company or the Employer deems appropriate to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

7.    Grant of Option. On the Enrollment Date of each Offering Period, each Eligible Employee participating in such Offering Period will be granted an option to purchase on each Exercise Date during such Offering Period (at the applicable Purchase Price) up to a number of Shares of Common Stock determined by dividing such Eligible Employee’s Contributions accumulated prior to such Exercise Date and retained in the Eligible Employee’s account as of the Exercise Date by the applicable Purchase Price; provided that in no event will an Eligible Employee be permitted to purchase during each Purchase Period more than a maximum number of Shares of Common Stock determined by the Administrator prior to the first Offering Period, if any (with such number subject to any adjustment pursuant to Section 19) and provided further that such purchase will be subject to the limitations set forth in Sections 3(c) and 13. The Eligible Employee may accept the grant of such option by electing to participate in the Plan in accordance with the requirements of Section 5. The Administrator may, for future Offering Periods, increase or decrease, in its absolute discretion, the maximum number of Shares of Common Stock that an Eligible Employee may purchase during each Purchase Period. Exercise of the option will occur as provided in Section 8, unless the Participant has withdrawn pursuant to Section 10. The option will expire on the last day of the Offering Period.

I-6

8.    Exercise of Option.

(a)    Unless a Participant withdraws from the Plan as provided in Section 10, his or her option for the purchase of Shares of Common Stock will be exercised automatically on each Exercise Date, and the maximum number of full Shares subject to the option will be purchased for such Participant at the applicable Purchase Price with the accumulated Contributions from his or her account. No fractional Shares of Common Stock will be purchased; any Contributions accumulated in a Participant’s account that are not sufficient to purchase a full Share will be retained in the Participant’s account for the subsequent Purchase Period or Offering Period, subject to earlier withdrawal by the Participant as provided in Section 10. Any other funds left over in a Participant’s account after the Exercise Date will be returned to the Participant. During a Participant’s lifetime, a Participant’s option to purchase Shares hereunder is exercisable only by him or her.

(b)    If the Administrator determines that, on a given Exercise Date, the number of Shares of Common Stock with respect to which options are to be exercised may exceed (i) the number of Shares of Common Stock that were available for sale under the Plan on the Enrollment Date of the applicable Offering Period, or (ii) the number of Shares of Common Stock available for sale under the Plan on such Exercise Date, the Administrator may in its sole discretion (x) provide that the Company will make a pro rata allocation of the Shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all Participants exercising options to purchase Common Stock on such Exercise Date, and continue all Offering Periods then in effect or (y) provide that the Company will make a pro rata allocation of the Shares of Common Stock available for purchase on such Enrollment Date or Exercise Date, as applicable, in as uniform a manner as will be practicable and as it will determine in its sole discretion to be equitable among all participants exercising options to purchase Common Stock on such Exercise Date, and terminate any or all Offering Periods then in effect pursuant to Section 20. The Company may make a pro rata allocation of the Shares available on the Enrollment Date of any applicable Offering Period pursuant to the preceding sentence, notwithstanding any authorization of additional Shares for issuance under the Plan by the Company’s stockholders subsequent to such Enrollment Date.

9.    Delivery. As soon as reasonably practicable after each Exercise Date on which a purchase of Shares of Common Stock occurs, the Company will arrange the delivery to each Participant of the Shares purchased upon exercise of his or her option in a form determined by the Administrator (in its sole discretion) and pursuant to rules established by the Administrator. The Company may permit or require that Shares be deposited directly with a broker designated by the Company or to a designated agent of the Company, and the Company may utilize electronic or automated methods of Share transfer. The Company may require that Shares be retained with such broker or agent for a designated period of time and/or may establish other procedures to permit tracking of disqualifying dispositions of such Shares. No Participant will have any voting, dividend, or other stockholder rights with respect to Shares of Common Stock subject to any option granted under the Plan until such Shares have been purchased and delivered to the Participant as provided in this Section 9.

10.    Withdrawal.

(a)    A Participant may withdraw all but not less than all the Contributions credited to his or her account and not yet used to exercise his or her option under the Plan at any time, subject to any limitations imposed by the Administrator and/or by Company policies, by (i) submitting to the Company’s stock administration office (or its designee) a written notice of withdrawal in the form determined by the Administrator for such purpose, or (ii) following an electronic or other withdrawal procedure determined by the Administrator. All of the Participant’s Contributions credited to his or her account will be paid to such Participant promptly after receipt of notice of withdrawal and such Participant’s option for the Offering Period will be automatically terminated, and no further Contributions for the purchase of Shares will be made for such Offering Period. If a Participant withdraws from an Offering Period, Contributions will not resume at the beginning of the succeeding Offering Period, unless the Participant re-enrolls in the Plan in accordance with the provisions of Section 5.

I-7

(b)    A Participant’s withdrawal from an Offering Period will not have any effect on his or her eligibility to participate in any similar plan that may hereafter be adopted by the Company or in succeeding Offering Periods that commence after the termination of the Offering Period from which the Participant withdraws.

11.    Termination of Employment. Upon a Participant’s ceasing to be an Eligible Employee for any reason, he or she will be deemed to have elected to withdraw from the Plan and the Contributions credited to such Participant’s account during the Offering Period but not yet used to purchase Shares of Common Stock under the Plan will be returned to such Participant or, in the case of his or her death, to the person or persons entitled thereto under Section 15, and such Participant’s option will be automatically terminated. Unless otherwise provided by the Administrator, a Participant whose employment transfers between entities through a termination with an immediate rehire (with no break in service) by the Company or a Designated Company will not be treated as terminated under the Plan.

12.    Interest. No interest will accrue on the Contributions of a participant in the Plan, except as may be required by Applicable Law, as determined by the Company, and if so required by the laws of a particular jurisdiction, except to the extent otherwise permitted by U.S. Treasury Regulation Section 1.423-2(f).

13.    Stock.

(a)    Subject to adjustment upon changes in capitalization of the Company as provided in Section 19 hereof, the maximum number of Shares of Common Stock that will be made available for sale under the Plan will be [●] Shares of Common Stock1; provided, that the total number of Shares that will be reserved, and that may be issued, under the Plan will automatically increase on the first trading day of each calendar year, beginning with calendar year 2023, by a number of Shares equal to one percent (1%) of the total number of Outstanding Shares on the last day of the prior calendar year. Notwithstanding the foregoing, the Administrator may act prior to January 1 of a given year to provide that there will be no such increase in the share reserve for that year or that the increase in the share reserve for such year will be a lesser number of Shares than provided herein.

(b)    Shares issued under the Plan may, in whole or in part, be authorized but unissued Shares or Shares that shall have been or may be reacquired by the Company in the open market, in private transactions or otherwise.

(c)    Until the Shares of Common Stock are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), a Participant will have only the rights of an unsecured creditor with respect to such Shares, and no right to vote or receive dividends or any other rights as a stockholder will exist with respect to such Shares.

(d)    Shares of Common Stock to be delivered to a Participant under the Plan will be registered in the name of the Participant or in the name of the Participant and his or her spouse, as the Participant may elect.

14.    Administration. The Plan will be administered by the Board or a Committee appointed by the Board, which Committee will be constituted to comply with Applicable Laws. The Administrator will have full and exclusive discretionary authority to: (i) construe, interpret and apply the terms of the Plan, (ii) delegate ministerial duties to any of the Company’s employees, (iii) supply omissions or correct defects in the Plan, (iv) designate separate Offerings under the Plan, (v) designate Subsidiaries of the Company as participating in the Plan, (vi) determine eligibility, (vii) adjudicate all disputed claims filed under the Plan and (viii) establish such procedures that it deems necessary for the administration of the Plan (including, without limitation, to adopt such procedures and sub-plans as are necessary or appropriate to permit the participation in the Plan by employees who are foreign nationals or employed outside the U.S., the terms of which sub-plans may take precedence over other provisions of this Plan, with the exception of Section 13(a) hereof, but unless otherwise

1  Note to Draft: Initial share reserve to equal 1% of total Shares.

I-8

superseded by the terms of such sub-plan, the provisions of this Plan will govern the operation of such sub-plan). Without limiting the generality of the foregoing, the Administrator is specifically authorized to adopt rules and procedures regarding eligibility to participate, the definition of Compensation, handling of Contributions, making of Contributions to the Plan (including, without limitation, in forms other than payroll deductions), establishment of bank or trust accounts to hold Contributions, payment of interest, conversion of local currency, obligations to pay payroll tax, determination of beneficiary designation requirements, withholding procedures and handling of stock certificates that vary with applicable local requirements. The Administrator also is authorized to determine that, to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f), the terms of an option granted under the Plan or an Offering to citizens or residents of a non-U.S. jurisdiction will be less favorable than the terms of options granted under the Plan or the same Offering to employees residing solely in the U.S. Every finding, decision, and determination made by the Administrator will, to the full extent permitted by law, be final and binding upon all parties.

15.    Designation of Beneficiary.

(a)    If permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any Shares of Common Stock and cash, if any, from the Participant’s account under the Plan in the event of such Participant’s death subsequent to an Exercise Date on which the option is exercised but prior to delivery to such Participant of such Shares and cash. In addition, if permitted by the Administrator, a Participant may file a designation of a beneficiary who is to receive any cash from the Participant’s account under the Plan in the event of such Participant’s death prior to exercise of the option. If a Participant is married and the designated beneficiary is not the spouse, spousal consent will be required for such designation to be effective.

(b)    Such designation of beneficiary may be changed by the Participant at any time by notice in a form determined by the Administrator. In the event of the death of a Participant and in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company will deliver such Shares and/or cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such Shares and/or cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company, then to such other person as the Company may designate.

(c)    All beneficiary designations will be in such form and manner as the Administrator may designate from time to time. Notwithstanding Sections 15(a) and (b) above, the Company and/or the Administrator may decide not to permit such designations by Participants in non-U.S. jurisdictions to the extent permitted by U.S. Treasury Regulation Section 1.423-2(f).

16.    Transferability. Neither Contributions credited to a Participant’s account nor any rights with regard to the exercise of an option or to receive Shares of Common Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 15 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition will be without effect, except that the Company may treat such act as an election to withdraw funds from an Offering Period in accordance with Section 10 hereof.

17.    Use of Funds. The Company may use all Contributions received or held by it under the Plan for any corporate purpose, and the Company will not be obligated to segregate such Contributions. Until Shares of Common Stock are issued, Participants will have only the rights of an unsecured creditor with respect to such Contributions and such Shares.

18.    Reports. Individual accounts will be maintained for each Participant in the Plan. Statements of account will be given to participating Eligible Employees at least annually, which statements will set forth the

I-9

amounts of Contributions, the Purchase Price, the number of Shares of Common Stock purchased and the remaining cash balance, if any.

19.    Adjustments, Dissolution, Liquidation, Merger, or Change in Control.

(a)    Adjustments. In the event that any dividend or other distribution (whether in the form of cash, Common Stock, other securities, or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Common Stock or other securities of the Company, or other change in the corporate structure of the Company affecting the Common Stock occurs, the Administrator, in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, will, in such manner as it may deem equitable, adjust the number and class of Common Stock that may be delivered under the Plan, the Purchase Price per share and the number of shares of Common Stock covered by each option under the Plan that has not yet been exercised, and the numerical limits of Sections 7 and 13.

(b)    Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, any Offering Period then in progress will be shortened by setting a New Exercise Date, and will terminate immediately prior to the consummation of such proposed dissolution or liquidation, unless provided otherwise by the Administrator. The New Exercise Date will be before the date of the Company’s proposed dissolution or liquidation. The Administrator will notify each Participant in writing or electronically, prior to the New Exercise Date, that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

(c)    Change in Control. In the event of a Change in Control, each outstanding option will be assumed or an equivalent option substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation fails to assume or substitute for the option, the Offering Period with respect to which such option relates will be shortened by setting a New Exercise Date on which such Offering Period will end. The New Exercise Date will occur before the date of the Company’s proposed merger or Change in Control. The Administrator will notify each Participant in writing or electronically prior to the New Exercise Date that the Exercise Date for the Participant’s option has been changed to the New Exercise Date and that the Participant’s option will be exercised automatically on the New Exercise Date, unless prior to such date, the Participant has withdrawn from the Offering Period as provided in Section 10 hereof.

20.    Amendment or Termination.

(a)    The Administrator, in its sole discretion, may amend, suspend, or terminate the Plan, or any part thereof, at any time and for any reason. If the Plan is terminated, the Administrator, in its discretion, may elect to terminate all outstanding Offering Periods either immediately or upon completion of the purchase of Shares of Common Stock on the next Exercise Date (which may be sooner than originally scheduled, if determined by the Administrator in its discretion), or may elect to permit Offering Periods to expire in accordance with their terms (and subject to any adjustment pursuant to Section 19). If the Offering Periods are terminated prior to expiration, all amounts then credited to Participants’ accounts that have not been used to purchase Shares of Common Stock will be returned to the Participants (without interest thereon, except as otherwise required under Applicable Laws, as further set forth in Section 12 hereof) as soon as administratively practicable.

(b)    Without stockholder consent and without limiting Section 20(a), the Administrator will be entitled to change the Offering Periods or Purchase Periods, designate separate Offerings, limit the frequency and/or number of changes in the amount withheld during an Offering Period, establish the exchange ratio applicable to amounts withheld in a currency other than U.S. dollars, permit Contributions in excess of the amount designated by a Participant in order to adjust for delays or mistakes in the Company’s processing of properly completed Contribution elections, establish reasonable waiting and adjustment periods and/or

I-10

accounting and crediting procedures to ensure that amounts applied toward the purchase of Common Stock for each Participant properly correspond with Contribution amounts, and establish such other limitations or procedures as the Administrator determines in its sole discretion advisable that are consistent with the Plan.

(c)    In the event the Administrator determines that the ongoing operation of the Plan may result in unfavorable financial accounting consequences, the Administrator may, in its discretion and, to the extent necessary or desirable, modify, amend or terminate the Plan to reduce or eliminate such accounting consequence including, but not limited to:

(i)    amending the Plan to conform with the safe harbor definition under the Financial Accounting Standards Board Accounting Standards Codification Topic 718 (or any successor thereto), including with respect to an Offering Period underway at the time;

(ii)    altering the Purchase Price for any Offering Period or Purchase Period including an Offering Period or Purchase Period underway at the time of the change in Purchase Price;

(iii)    shortening any Offering Period or Purchase Period by setting a New Exercise Date, including an Offering Period or Purchase Period underway at the time of the Administrator action;

(iv)    reducing the maximum percentage of Compensation a Participant may elect to set aside as Contributions; and

(v)    reducing the maximum number of Shares of Common Stock a Participant may purchase during any Offering Period or Purchase Period.

Such modifications or amendments will not require stockholder approval or the consent of any Participants.

21.    Notices. All notices or other communications by a Participant to the Company under or in connection with the Plan will be deemed to have been duly given when received in the form and manner specified by the Company at the location, or by the person, designated by the Company for the receipt thereof.

22.    Conditions Upon Issuance of Shares. Shares of Common Stock will not be issued with respect to an option unless the exercise of such option and the issuance and delivery of such Shares pursuant thereto will comply with all applicable provisions of law, domestic or foreign, including, without limitation, the U.S. Securities Act of 1933, as amended, the Exchange Act, the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the Shares may then be listed, and will be further subject to the approval of counsel for the Company with respect to such compliance.

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned applicable provisions of law.

23.    Section 409A of the Code. The Plan is exempt from the application of Section 409A of the Code and any ambiguities herein will be interpreted to so be exempt from Section 409A of the Code. In furtherance of the foregoing and notwithstanding any provision in the Plan to the contrary, if the Administrator determines that an option granted under the Plan may be subject to Section 409A of the Code or that any provision in the Plan would cause an option under the Plan to be subject to Code Section 409A, the Administrator may amend the terms of the Plan and/or of an outstanding option granted under the Plan, or take such other action the Administrator determines is necessary or appropriate, in each case, without the Participant’s consent, to exempt any outstanding option or future option that may be granted under the Plan from or to allow any such options to comply with Section 409A of the Code, but only to the extent any such amendments or action by the Administrator would not violate Code Section 409A. Notwithstanding the foregoing, the Company will have no liability to a Participant or any other party if any option to purchase Common Stock under the Plan that is intended to be exempt from or compliant with Section 409A of the Code is not so exempt or compliant or for any

I-11

action taken by the Administrator with respect thereto. The Company makes no representation that any option to purchase Common Stock under the Plan is compliant with Section 409A of the Code.

24.    Term of Plan. The Plan will become effective upon approval by the stockholders. It will continue in effect for a term of ten (10) years, unless sooner terminated under Section 20.

25.    Stockholder Approval. The Plan will be subject to approval by the stockholders of the Company within twelve (12) months after the date the Plan is adopted by the Board. Such stockholder approval will be obtained in the manner and to the degree required under Applicable Laws.

26.    Governing Law. The Plan will be governed by, and construed in accordance with, the laws of the State of Delaware (except its choice-of-law provisions).

27.    No Right to Employment. Participation in the Plan by a Participant will not be construed as giving a Participant the right to be retained as an employee of the Company or a Subsidiary or affiliate of the Company, as applicable. Further, the Company or a Subsidiary or affiliate of the Company may dismiss a Participant from employment at any time, free from any liability or any claim under the Plan.

28.    Severability. If any provision of the Plan is or becomes or is deemed to be invalid, illegal, or unenforceable for any reason in any jurisdiction or as to any Participant, such invalidity, illegality or unenforceability will not affect the remaining parts of the Plan, and the Plan will be construed and enforced as to such jurisdiction or Participant as if the invalid, illegal or unenforceable provision had not been included.

29.    Compliance with Applicable Laws. The terms of this Plan are intended to comply with all Applicable Laws and will be construed accordingly.

Notwithstanding such return or cancellation (x) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (y) unless and until this Subscription Agreement is terminated in accordance with Section 7 herein, Subscriber shall remain obligated (A) to redeliver funds to the Company in escrow following the Company’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 2.

(ii) all conditions precedent to the closing of the Transactions set forth in the Transaction Agreement shall have been satisfied (as determined by the parties to the Transaction Agreement) or waived (other than those conditions which, by their nature, are to be satisfied at the closing of the Transactions pursuant to the Transaction Agreement or by the Closing itself, but subject to their

J-2

satisfaction or valid waiver at the closing of the Transactions), and the closing of the Transactions shall be scheduled to occur substantially concurrently with or immediately following the Closing; and

(iii) no governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making the consummation of the transactions contemplated hereby illegal or otherwise restraining or prohibiting consummation of the transactions or the Subscription contemplated hereby and no such governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition.

(d) The obligation of the Company to consummate the Closing shall be subject to the satisfaction or valid waiver in writing by the Company of the additional conditions that, on the Closing Date:

(i) all representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined below), which representations and warranties shall be true and correct in all respects) at and as of the Closing Date; and

(ii) Subscriber shall not be in material breach of any covenant, agreement or condition required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

(a) The Company (i) is duly organized, validly existing and in good standing under the laws of its jurisdiction of incorporation, (ii) has the requisite power and authority to own, lease and operate its properties, to carry on its business as it is now being conducted and to enter into, deliver and perform its obligations under this Subscription Agreement, and (iii) is duly licensed or qualified to conduct its business and, if applicable, is in good standing under the laws of each jurisdiction (other than its jurisdiction of incorporation) in which the conduct of its business or the ownership of its properties or assets requires such license or qualification, except, with respect to the foregoing clause (iii), where the failure to be in good standing would not reasonably be

J-3

expected to have a Company Material Adverse Effect. For purposes of this Subscription Agreement, a “Company Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to the Company and its subsidiaries, taken together as a whole (on a consolidated basis), that, individually or in the aggregate, would reasonably be expected to have a material adverse effect on the Company’s ability to consummate the transactions contemplated hereby, including the issuance and sale of the Subscribed Shares.

(b) As of the Closing Date, the Subscribed Shares will be duly authorized and, when issued and delivered to Subscriber against full payment therefor in accordance with the terms of this Subscription Agreement, will be validly issued, fully paid and non-assessable and will not have been issued in violation of any preemptive rights created under the Company’s organizational documents (as adopted on or prior to the Closing Date), by contract, or the laws of its jurisdiction of incorporation.

(c) This Subscription Agreement has been duly authorized, executed and delivered by the Company, and assuming the due authorization, execution and delivery of the same by Subscriber and Fathom, this Subscription Agreement constitutes the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

(d) The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect.

(e) The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including a national securities exchange such as the New York Stock Exchange (such national securities exchange, the “Stock Exchange”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable state securities laws, (ii), the filing of the Registration Statement pursuant to Section 6 below, (iii) those required by the Stock Exchange, including with respect to obtaining stockholder approval, (iv) those required to consummate the Transactions as provided under the Transaction Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, and (vi) other filings, the failure of which to obtain would not reasonably be expected to have a Company Material Adverse Effect.

(f) Except for such matters as have not had and would not reasonably be expected to have a Company Material Adverse Effect, there is no (i) suit, action, investigation, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or any of its directors or officers in their capacities as such or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against the Company or any of its directors or officers in their capacities as such.

(g) Assuming the accuracy of Subscriber’s representations and warranties set forth in Section 5 of this Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Shares by the Company to Subscriber.

J-4

(h) Neither the Company nor any person acting on its behalf has engaged or will engage in any form of general solicitation or general advertising (within the meaning of Regulation D under the Securities Act) in connection with any offer or sale of the Collective Subscribed Shares. Neither the Company nor any person acting on its behalf has offered or will offer any of the Collective Subscribed Shares in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

(i) The Company is in compliance with all applicable laws and has not received any written communication from a governmental entity that alleges that the Company is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

(j) Except for J.P. Morgan Securities LLC (“JPM”) and Stifel, Nicolaus & Company, Incorporated (“Stifel” and together with JPM, the “Placement Agents”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares to Subscriber.

(k) The Company has filed each form, report, statement, schedule, prospectus, proxy and registration statement (the “SEC Documents”) that the Company was required to file with the Securities and Exchange Commission (the “Commission”) since its initial registration of the Class A Common Shares with the Commission and through the date hereof. As of their respective filing dates (the “Filing Dates”), the SEC Documents complied in all material respects with the requirements of the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder and currently in effect at the Filing Date, and none of the SEC Documents, when filed, or if amended prior to the date of this Subscription Agreement, as of the date of such amendment with respect to those disclosures that were amended, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. A copy of each SEC Document is available to Subscriber via the Commission’s EDGAR system. As of the date hereof, there are, and upon Closing there shall be, no outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the Commission with respect to any of the SEC Documents.

(l) As of the date hereof, the Company’s issued and outstanding Class A ordinary shares (“Class A ordinary shares”) are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “ATMR” (it being understood that the trading symbol will be changed in connection with the Transactions). Except as disclosed in the SEC Documents, as of the date hereof, there is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company by NYSE or the SEC, respectively, to prohibit or terminate the listing of the Company’s shares on NYSE or to deregister the shares under the Exchange Act. The Company has taken no action that is designed to terminate the registration of the shares under the Exchange Act. Upon consummation of the Transactions, the issued and outstanding shares of Class A Common Shares will continue to be registered pursuant to Section 12(b) of the Exchange Act and will be listed for trading on the Stock Exchange (as defined herein).

(m) The Company is not, and immediately after receipt of payment for the Subscribed Shares and consummation of the Transactions, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(n) Other than the Other Subscription Agreements entered into with the Other Subscribers, neither the Company nor Fathom has entered into any side letter or similar agreement that materially benefits any Other Subscriber (in such Other Subscriber’s capacity as an Other Subscriber) with respect to the terms of the Subscription. No Other Subscription Agreement or other document with respect to any PIPE Investment includes terms and conditions with respect to the Subscription that are more materially advantageous to any Other Subscriber (in such Other Subscriber’s capacity as an Other Subscriber) or other party than to Subscriber

J-5

hereunder, and there has been no amendment, modification or waiver under any such Other Subscription Agreements following the date of the Subscription Agreement.

(o) As of the date of this Subscription Agreement, the authorized capital stock of the Company consists of (a) 500,000,000 shares of Class A ordinary shares, par value $0.0001 per share, of which 34,500,000 are issued and outstanding, (b) 50,000,000 shares of Class B ordinary shares, par value $0.0001 per share (“Class B ordinary shares”), of which 8,625,000 are issued and outstanding, and (c) 5,000,000 preference shares, par value $0.0001 per share (“Preferred Shares”), of which no shares are issued and outstanding.

(c) The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by Fathom with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Fathom pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Fathom is a party or by which Fathom is bound or to which any of the property or assets of Fathom is subject; (ii) the organizational documents of Fathom; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Fathom or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Fathom Material Adverse Effect.

(e) Subscriber understands that the Subscribed Shares are being offered in transactions not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber understands that the Subscribed Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and as a result of these transfer restrictions, Subscriber may not be able to readily resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed Shares for an indefinite period of time.

(a) The Company agrees that the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”) no later than (30) calendar days after the Closing Date, and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days after the filing thereof (or, in the event the Commission reviews and has written comments to the Registration Statement, the ninetieth (90th) calendar day following the

J-10

filing thereof) and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review ((i) and (ii) collectively, the “Effectiveness Deadline”); provided, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business. The Company will use its commercially reasonable efforts to provide a draft of the Registration Statement to the undersigned for review and comment at least two (2) Business Days in advance of filing the Registration Statement; provided that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. Unless otherwise agreed to in writing by Subscriber, Subscriber shall not be identified as a statutory underwriter in the Registration Statement unless requested by the Commission or another regulatory agency; provided, that if the Commission or another regulatory agency requests that a Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement prior to the Registration Statement becoming effective upon its prompt written request to the Company. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number of Subscribed Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule 415 under the Securities Act, the Company shall amend the Registration Statement or file a new Registration Statement to register such additional Subscribed Shares that were not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the Company will use its commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber until the earlier of (i) two years from the issuance of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). If requested by Subscriber, the Company shall use its commercially reasonable efforts to (i) cause the removal of the restrictive legends from any Subscribed Shares being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of such Registrable Securities (as defined below) and, at the request of a Holder (as defined below), cause the removal of all restrictive legends from any Registrable Securities held by such Holder that may be sold by such Holder without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions, and (ii) cause its legal counsel to deliver an opinion, if necessary, to the transfer agent in connection with the instruction under subclause (i) to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, in each case upon the receipt of customary representations and other documentation, if any, from the Holder as reasonably requested by the Company, its counsel or the transfer agent, establishing that restrictive legends are no longer required. Any costs related to the foregoing, including fees of the transfer agent, DTC and legal counsel to the Company shall be borne by the Company. The Company will use commercially reasonable efforts to make and keep public information available (as those terms are understood and defined in Rule 144) and file all reports, and provide all customary and reasonable cooperation, necessary to enable Holder to resell Registrable Securities pursuant to the Registration Statement or Rule 144, as applicable, qualify the Registrable Securities for listing on the applicable stock exchange on which the Company’s Class A Common Shares are then listed and update or amend the Registration Statement as necessary to include Registrable Securities. “Registrable Securities” shall mean, as of any date of determination, the Subscribed Shares and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, provided, however, that such securities shall cease to be Registrable Securities at

J-11

the earliest of (A) three (3) years, (B) the date all Subscribed Shares held by a Holder may be sold by such Holder without volume or manner of sale limitations pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), (C) the date on which such securities have actually been sold by a Holder, or (D) when such securities shall have ceased to be outstanding. “Holder” shall mean Subscriber or any affiliate of Subscriber to which the rights under this Section 6 shall have been assigned. The Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer Subscriber Shares. In the case of the registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained herein, the Company may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if, in the reasonable determination of the Company’s board of directors, upon advice of legal counsel, such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially adversely affect the Company (each such circumstance, a “Suspension Event”); provided, that, (w) the Company shall not so delay filing or so suspend the use of the Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period and (x) the Company shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter.

(b) In the case of the registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. At its expense the Company shall:

(i) advise Subscriber, as expeditiously as possible:

(i) when a Registration Statement or any amendment thereto has been filed with the Commission;

(ii) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(iv) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Company

J-12

other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (i) through (iv) above constitutes material, nonpublic information regarding the Company.

(ii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iii) upon the occurrence of any event contemplated in Section 6(b)(i)(iv) above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Subscribed Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(iv) use its commercially reasonable efforts to allow Subscriber to review disclosure regarding Subscriber in the Registration Statement; and

(v) otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by Subscriber, consistent with the terms of this Subscription Agreement, in connection with the registration of the Subscribed Shares.

(c) Upon receipt of any written notice from the Company (which notice shall not contain any material non-public information regarding the Company) of the occurrence of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, the undersigned agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by the Company, the undersigned will deliver to the Company, or in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (w) to the extent the undersigned is required to retain a copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up.

Section 7. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is validly terminated in accordance with its terms without being consummated, (b) upon the mutual written agreement of all parties hereto to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transactions, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated or (d) by written notice from Subscriber or any other party given anytime on or after December 31, 2021, if the Closing has not occurred by such date and the terminating party’s breach was not the primary reason

J-13

the Closing failed to occur by such date, (the termination events described in clauses (a)–(d) above, collectively, the “Termination Events”); provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination or common law intentional fraud in the making of any representation or warranty hereunder, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach or fraud. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof. Upon the occurrence of any Termination Event, except as set forth in the proviso to the first sentence of this Section 7, this Subscription Agreement shall be void and of no further effect and any portion of the Purchase Price paid by Subscriber to Company in connection herewith shall promptly (and in any event within two business days) following the Termination Event be returned to Subscriber.

Section 8. Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, in each case arising out of or as a result of, in connection with or relating in any way to this Subscription Agreement and the transactions contemplated by this Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of this Subscription Agreement and the transactions contemplated by this Subscription Agreement, and (c) will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of shares of Class A Common Shares of the Company acquired by any means other than pursuant to this Subscription Agreement.

Section 9. Indemnity.

(a) The Company agrees to indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, and officers, employees, and agents, and each person who controls Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of Subscriber (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by or on behalf of Subscriber expressly for use therein.

(b) Subscriber agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements, to indemnify and hold harmless the Company, its directors, officers, employees and agents, and each person who controls the Company (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Company against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements

J-14

therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing to the Company by or on behalf of Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by the Company upon the sale of the Subscribed Shares purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation. Each of the Company and Fathom acknowledge and agree that each purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of each of the respective acknowledgments, understandings, agreements, representations and warranties herein (as modified by such notice) made by each of the Company and Fathom as of the time of such purchase.

(c) Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Subscribed Shares purchased pursuant to this Subscription Agreement.

(e) If the indemnification provided under this Section 9 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 9 from any person who was not guilty of such fraudulent misrepresentation. Any contribution pursuant to this Section 9(e) by any seller of Subscribed Shares shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Subscribed Shares pursuant to the Registration Statement. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Subscription Agreement.

J-15

Section 10. Miscellaneous.

(a) All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date and time of transmission to such recipient, provided that no electronic mail is undeliverable or other rejection notice is generated, (iii) one Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address or electronic mail address, as applicable, specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 10(a).

(b) Subscriber acknowledges that the Company, Fathom and the Placement Agents will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company, Fathom and the Placement Agents if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that each purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase. Each of the Company and Fathom acknowledge that Subscriber and Placement Agents will rely on the respective acknowledgments, understandings, agreements, representations and warranties made by each of the Company and Fathom contained in this Subscription Agreement. Prior to the Closing, each of the Company and Fathom agree to promptly notify Subscriber and Placement Agents if they become aware that any of their respective acknowledgments, understandings, agreements, representations and warranties set forth herein are no longer accurate in all material respects.

(c) Each of the Company, Fathom, the Placement Agents, Subscriber and any other person or entity against whom a claim is brought with respect to the purchase of the Subscribed Shares is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.

(d) Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein, except as expressly set forth herein.

(e) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired hereunder and Subscriber’s rights under Section 6 hereof) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transactions and exclusively to another entity under the control of, or under common control with, the Company), provided that no such assignment shall relieve the Company of its obligations hereunder if any such assignee fails to perform such obligations. Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates, other investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber or, with the Company’s prior written consent, to another person, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations.

(f) All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transactions, all representations, warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transactions and remain in full force and effect.

J-16

(g) The Company may request from Subscriber such additional information as the Company may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares and to register the Subscribed Shares for resale, and Subscriber shall provide such information as may be reasonably requested to the extent readily available and to the extent consistent with Subscriber’s internal policies and procedures; provided that the Company agrees to keep any such information provided by Subscriber confidential except to the extent such disclosure is required in connection with registration of the Subscribed Shares for resale, by law, at the request of the staff of the Commission or under the regulations of the Stock Exchange. Subscriber acknowledges that subject to the conditions set forth in Section 10(t), the Company may file a copy of this Subscription Agreement with the Commission as an exhibit to a periodic report of the Company or a registration statement of the Company.

(h) This Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto.

(i) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.

(j) Except as otherwise provided herein (including the next sentence hereof), this Subscription Agreement is intended for the benefit of the parties hereto and their respective affiliates and their respective heirs, executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. Except as set forth in Section 10(b), Section 10(c), Section 10(e) and this Section 10(j), this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns, and the parties hereto acknowledge that such persons so referenced are third party beneficiaries of this Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions.

(k) The parties hereto acknowledge and agree that (i) this Subscription Agreement is being entered into in order to induce the Company and Fathom to execute and deliver the Transaction Agreement and (ii) irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company and Fathom shall each be entitled to specifically enforce Subscriber’s obligations to fund the Subscription Amount and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 10(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(l) In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document, instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred and documented by the

J-17

prevailing party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby.

(m) If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(n) No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

(o) This Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(p) This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

(q) EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.

(r) The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the United States District Court for the Southern District of New York, the Supreme Court of the State of New York or the federal courts of the United States of America located in the State of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any

J-18

dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 10(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

Section 1. Subscription. Subject to the terms and conditions hereof, at the Closing (as defined below), Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such subscription and issuance, the “Subscription”).

Notwithstanding such return or cancellation (x) a failure to close on the anticipated Closing Date shall not, by itself, be deemed to be a failure of any of the conditions to Closing set forth in this Section 2 to be satisfied or waived on or prior to the Closing Date, and (y) unless and until this Subscription Agreement is terminated in accordance with Section 7 herein, Subscriber shall remain obligated (A) to redeliver funds to the Company in escrow following the Company’s delivery to Subscriber of a new Closing Notice and (B) to consummate the Closing upon satisfaction of the conditions set forth in this Section 2.

(i) all representations and warranties of Subscriber contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Subscriber Material Adverse Effect (as defined below), which representations and warranties shall be true and correct in all respects) at and as of the Closing Date; and

(ii) Subscriber shall not be in material breach of any covenant, agreement or condition required by this Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

(c) This Subscription Agreement has been duly authorized, executed and delivered by the Company, and assuming the due authorization, execution and delivery of the same by Subscriber and Fathom, this Subscription Agreement constitutes the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

(d) The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect.

(e) The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including a national securities exchange such as the New York Stock Exchange (such national securities exchange, the “Stock Exchange”)) or other person in connection with the execution, delivery and performance of this Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable state securities laws, (ii), the filing of the Registration Statement pursuant to Section 6 below, (iii) those required by the Stock Exchange, including with respect to obtaining stockholder approval, (iv) those required to consummate the Transactions as provided under the Transaction Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, and (vi) other filings, the failure of which to obtain would not reasonably be expected to have a Company Material Adverse Effect.

(f) Except for such matters as have not had and would not reasonably be expected to have a Company Material Adverse Effect, there is no (i) suit, action, investigation, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or any of its directors or officers in their capacities as such or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against the Company or any of its directors or officers in their capacities as such.

acting on its behalf has offered or will offer any of the Collective Subscribed Shares in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

(i) The Company is in compliance with all applicable laws and has not received any written communication from a governmental entity that alleges that the Company is not in compliance with or is in default or violation of any applicable law, except where such non-compliance, default or violation would not, individually or in the aggregate, reasonably be expected to have a Company Material Adverse Effect.

(j) Except for J.P. Morgan Securities LLC (“JPM”) and Stifel, Nicolaus & Company, Incorporated (“Stifel” and together with JPM, the “Placement Agents”), no broker or finder is entitled to any brokerage or finder’s fee or commission solely in connection with the sale of the Subscribed Shares to Subscriber.

(k) The Company has filed each form, report, statement, schedule, prospectus, proxy and registration statement (the “SEC Documents”) that the Company was required to file with the Securities and Exchange Commission (the “Commission”) since its initial registration of the Class A Common Shares with the Commission and through the date hereof. As of their respective filing dates (the “Filing Dates”), the SEC Documents complied in all material respects with the requirements of the Securities Act, the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the Commission promulgated thereunder and currently in effect at the Filing Date, and none of the SEC Documents, when filed, or if amended prior to the date of this Subscription Agreement, as of the date of such amendment with respect to those disclosures that were amended, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. A copy of each SEC Document is available to Subscriber via the Commission’s EDGAR system. As of the date hereof, there are, and upon Closing there shall be, no outstanding or unresolved comments in comment letters from the staff of the Division of Corporation Finance of the Commission with respect to any of the SEC Documents.

(l) As of the date hereof, the Company’s issued and outstanding Class A ordinary shares (“Class A ordinary shares”) are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the New York Stock Exchange (“NYSE”) under the symbol “ATMR” (it being understood that the trading symbol will be changed in connection with the Transactions). Except as disclosed in the SEC Documents, as of the date hereof, there is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company by NYSE or the SEC, respectively, to prohibit or terminate the listing of the Company’s shares on NYSE or to deregister the shares under the Exchange Act. The Company has taken no action that is designed to terminate the registration of the shares under the Exchange Act. Upon consummation of the Transactions, the issued and outstanding shares of Class A Common Shares will continue to be registered pursuant to Section 12(b) of the Exchange Act and will be listed for trading on the Stock Exchange (as defined herein).

(m) The Company is not, and immediately after receipt of payment for the Subscribed Shares and consummation of the Transactions, will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

(n) Other than the Other Subscription Agreements entered into with the Other Subscribers, neither the Company nor Fathom has entered into any side letter or similar agreement that materially benefits any Other Subscriber (in such Other Subscriber’s capacity as an Other Subscriber) with respect to the terms of the Subscription. No Other Subscription Agreement or other document with respect to any PIPE Investment includes terms and conditions with respect to the Subscription that are more materially advantageous to any Other Subscriber (in such Other Subscriber’s capacity as an Other Subscriber) or other party than to Subscriber hereunder, and there has been no amendment, modification or waiver under any such Other Subscription Agreements following the date of the Subscription Agreement.

(c) The execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by Fathom with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of Fathom pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Fathom is a party or by which Fathom is bound or to which any of the property or assets of Fathom is subject; (ii) the organizational documents of Fathom; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Fathom or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Fathom Material Adverse Effect.

(e) Subscriber understands that the Subscribed Shares are being offered in transactions not involving any public offering within the meaning of the Securities Act and that the Subscribed Shares have not been registered under the Securities Act. Subscriber understands that the Subscribed Shares may not be offered, resold, transferred, pledged or otherwise disposed of by Subscriber absent an effective registration statement under the Securities Act, except (i) to the Company or a subsidiary thereof, or (ii) pursuant to an applicable exemption from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and as a result of these transfer restrictions, Subscriber may not be able to readily resell the Subscribed Shares and may be required to bear the financial risk of an investment in the Subscribed Shares for an indefinite period of time. Subscriber acknowledges and agrees that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or

J-35

disposition pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”) until at least one year from the Closing Date. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the Subscribed Shares.

Subscriber further acknowledges that there have not been, and Subscriber hereby agrees that it is not relying on, any of the respective representations, warranties, covenants or agreements made to Subscriber by each of the Company, Fathom, the Placement Agents, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives, any other party to the Transactions or any other person or entity, expressly or by implication, other than the respective representations, warranties, covenants and agreements of each of the Company and Fathom expressly set forth in this Subscription Agreement. Subscriber acknowledges that certain information provided to Subscriber was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections. Subscriber agrees that neither of the Placement Agents, nor any of their respective affiliates or any of their or their respective affiliates’ control persons, officers, directors or employees, shall be liable to Subscriber pursuant to this Subscription Agreement for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Subscribed Shares. On behalf of itself and its affiliates, Subscriber releases each of the Placement Agents in respect of any losses, claims, damages, obligations, penalties, judgments, awards, liabilities, costs, expenses or disbursements related to this Subscription Agreement or the transactions contemplated hereby.

(g) In making its decision to purchase the Subscribed Shares, Subscriber has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the Company and its subsidiaries and the Transactions. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Without limiting the generality of the foregoing, Subscriber acknowledges that it has received (or in the case of documents filed with the Commission, had access to) the Company’s filings with the Commission and any disclosure documents provided by or on behalf of the Company or Fathom in connection with this Subscription. Subscriber acknowledges that no statement or printed material contrary to any such disclosure documents has been made or given to Subscriber by or on behalf of the Company or Fathom. Subscriber acknowledges and agrees that none of the Placement Agents, or any affiliate of the Placement Agents, has provided Subscriber with any information or advice with respect to the Subscribed Shares nor is such information or advice necessary or desired. None of the Placement Agents or any of their respective affiliates has made or makes any representation as to the Company or Fathom or the quality or value of the Subscribed Shares and the Placement Agents and any of their respective affiliates may have acquired non-public information with respect to the Company or the Acquired Companies which Subscriber agrees need not be provided to it. In connection with the issuance of the Subscribed Shares to Subscriber, (a) none of the Placement Agents or any of their respective affiliates has acted as a financial advisor or fiduciary to Subscriber, and (b) each of the Placement Agents is acting solely as placement agent to the Company and is not acting as an underwriter or in any other capacity or as a fiduciary for the Company, Fathom or any other person or entity in connection with the Transaction and (c) none of the Placement Agents or any of their respective affiliates has prepared any disclosure or offering document in connection with the offer and sale of the Subscribed Shares. Subscriber acknowledges that the Placement Agents and their respective directors, officers, employees, representatives and controlling persons have made no independent investigation with respect to the Company, Fathom or the Subscribed Shares or the accuracy, completeness or adequacy of any information supplied to Subscriber by the Company and/or Fathom.

(h) Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact between Subscriber and the Company, Fathom, or their respective representatives or affiliates, or by means of

J-36

contact from the Placement Agents and the Subscribed Shares were offered to Subscriber solely by direct contact between Subscriber and the Company, Fathom or their respective affiliates. Subscriber did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means. Subscriber acknowledges that the Company represents and warrants that the Subscribed Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

(i) Subscriber acknowledges and agrees that (i) the Placement Agents have not made and will not make any representation or warranty, whether express or implied, of any kind or character and have not provided any advice or recommendation in connection with the Transactions, and (ii) the Placement Agents will have no responsibility with respect to (A) any representations, warranties or agreements made by any person or entity under or in connection with the Transactions or any of the documents furnished pursuant thereto or in connection therewith, or the execution, legality, validity or enforceability (with respect to any person) or any thereof, or (B) the business, affairs, financial condition, operations, properties or prospects of, or any other matter concerning the Company, Fathom or the Transactions.

(j) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares. Subscriber has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, and Subscriber has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as Subscriber has considered necessary to make an informed investment decision.

(k) Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

(l) Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment.

(m) Subscriber is not, and is not owned or controlled by or acting on behalf of (in connection with the Transactions), a Sanctioned Person. Subscriber is not a non-U.S. shell bank or providing banking services to a non-U.S. shell bank. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber also represents that it maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed for the screening of any investors against Sanctions-related lists of blocked or restricted persons. Subscriber further represents and warrants that, to its best knowledge, the funds held by Subscriber and used to purchase the Subscribed Shares are derived from lawful activities. For purposes of this Agreement, “Sanctioned Person” means at any time any person or entity: (a) listed on any Sanctions-related list of designated or blocked or restricted persons; (b) that is a national of, the government of, or any agency or instrumentality of the government of, or resident in, or organized under the laws of, a country or territory that is the target of comprehensive Sanctions from time to time (as of the date of this Agreement, Cuba, Iran, North Korea, Syria, and the Crimea region); or (c) owned or controlled by or acting on behalf of any of the foregoing. “Sanctions” means those trade, economic and financial sanctions laws, regulations, embargoes, and restrictive measures (in each case having the force of law) administered, enacted or enforced from time to time by (a) the United States (including without limitation the U.S. Department of the Treasury, Office of Foreign Assets Control, the U.S. Department of State, and the U.S. Department of

Part 800.244) will acquire a substantial interest in the Company as a result of the purchase and sale of Subscribed Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R. Part 800.208) over the Company from and after the Closing as a result of the purchase and sale of Subscribed Shares hereunder.

(p) If Subscriber is an employee benefit plan that is subject to Title I of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”), a plan, an individual retirement account or other arrangement that is subject to section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”) or an employee benefit plan that is a governmental plan (as defined in section 3(32) of ERISA), a church plan (as defined in section 3(33) of ERISA), a non-U.S. plan (as described in section 4(b)(4) of ERISA) or other plan that is not subject to the foregoing but may be subject to provisions under any other federal, state, local, non-U.S. or other laws or regulations that are similar to such provisions of ERISA or the Code, or an entity whose underlying assets are considered to include “plan assets” of any such plan, account or arrangement (each, a “Plan”) subject to the fiduciary or prohibited Transactions provisions of ERISA or section 4975 of the Code, Subscriber represents and warrants that (i) neither the Company, nor any of its respective affiliates (the “Transactions Parties”) has acted as the Plan’s fiduciary, or has been relied on for advice, with respect to its decision to acquire and hold the Subscribed Shares, and none of the Transactions Parties shall at any time be relied upon as the Plan’s fiduciary with respect to any decision to acquire, continue to hold or transfer the Subscribed Shares and (ii) none of the acquisition, holding and/or transfer or disposition of the Subscribed Shares will result in a non-exempt prohibited Transactions under ERISA or Section 4975 of the Code or any similar law or regulation.

Section 6. Registration of Subscribed Shares.

(a) The Company agrees that the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”) no later than (30) calendar days after the Closing Date, and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days after the filing thereof (or, in the event the Commission reviews and has written comments to the Registration Statement, the ninetieth (90th) calendar day following the

J-38

filing thereof) and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review ((i) and (ii) collectively, the “Effectiveness Deadline”); provided, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business. The Company will use its commercially reasonable efforts to provide a draft of the Registration Statement to the undersigned for review and comment at least two (2) Business Days in advance of filing the Registration Statement; provided that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. Unless otherwise agreed to in writing by Subscriber, Subscriber shall not be identified as a statutory underwriter in the Registration Statement unless requested by the Commission or another regulatory agency; provided, that if the Commission or another regulatory agency requests that a Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement prior to the Registration Statement becoming effective upon its prompt written request to the Company. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number of Subscribed Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule 415 under the Securities Act, the Company shall amend the Registration Statement or file a new Registration Statement to register such additional Subscribed Shares that were not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the Company will use its commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber until the earlier of (i) two years from the issuance of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). If requested by Subscriber, the Company shall use its commercially reasonable efforts to (i) cause the removal of the restrictive legends from any Subscribed Shares being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of such Registrable Securities (as defined below) and, at the request of a Holder (as defined below), cause the removal of all restrictive legends from any Registrable Securities held by such Holder that may be sold by such Holder without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions, and (ii) cause its legal counsel to deliver an opinion, if necessary, to the transfer agent in connection with the instruction under subclause (i) to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, in each case upon the receipt of customary representations and other documentation, if any, from the Holder as reasonably requested by the Company, its counsel or the transfer agent, establishing that restrictive legends are no longer required. Any costs related to the foregoing, including fees of the transfer agent, DTC and legal counsel to the Company shall be borne by the Company. The Company will use commercially reasonable efforts to make and keep public information available (as those terms are understood and defined in Rule 144) and file all reports, and provide all customary and reasonable cooperation, necessary to enable Holder to resell Registrable Securities pursuant to the Registration Statement or Rule 144, as applicable, qualify the Registrable Securities for listing on the applicable stock exchange on which the Company’s Class A Common Shares are then listed and update or amend the Registration Statement as necessary to include Registrable Securities. “Registrable Securities” shall mean, as of any date of determination, the Subscribed Shares and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, provided, however, that such securities shall cease to be Registrable Securities at

J-39

the earliest of (A) three (3) years, (B) the date all Subscribed Shares held by a Holder may be sold by such Holder without volume or manner of sale limitations pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), (C) the date on which such securities have actually been sold by a Holder, or (D) when such securities shall have ceased to be outstanding. “Holder” shall mean Subscriber or any affiliate of Subscriber to which the rights under this Section 6 shall have been assigned. The Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer Subscriber Shares. In the case of the registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained herein, the Company may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if, in the reasonable determination of the Company’s board of directors, upon advice of legal counsel, such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially adversely affect the Company (each such circumstance, a “Suspension Event”); provided, that, (w) the Company shall not so delay filing or so suspend the use of the Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period and (x) the Company shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter.

(b) In the case of the registration effected by the Company pursuant to this Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. At its expense the Company shall:

(i) advise Subscriber, as expeditiously as possible:

(i) when a Registration Statement or any amendment thereto has been filed with the Commission;

(ii) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(iv) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading.

Notwithstanding anything to the contrary set forth herein, the Company shall not, when so advising Subscriber of such events, provide Subscriber with any material, nonpublic information regarding the Company

J-40

other than to the extent that providing notice to Subscriber of the occurrence of the events listed in (i) through (iv) above constitutes material, nonpublic information regarding the Company.

(ii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iii) upon the occurrence of any event contemplated in Section 6(b)(i)(iv) above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Subscribed Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(iv) use its commercially reasonable efforts to allow Subscriber to review disclosure regarding Subscriber in the Registration Statement; and

(v) otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by Subscriber, consistent with the terms of this Subscription Agreement, in connection with the registration of the Subscribed Shares.

(c) Upon receipt of any written notice from the Company (which notice shall not contain any material non-public information regarding the Company) of the occurrence of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, the undersigned agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by the Company, the undersigned will deliver to the Company, or in the undersigned’s sole discretion destroy, all copies of the prospectus covering the Subscribed Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (w) to the extent the undersigned is required to retain a copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up.

Section 7. Termination. This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is validly terminated in accordance with its terms without being consummated, (b) upon the mutual written agreement of all parties hereto to terminate this Subscription Agreement, (c) if, on the Closing Date of the Transactions, any of the conditions to Closing set forth in Section 2 of this Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Subscription Agreement are not consummated or (d) by written notice from Subscriber or any other party given anytime on or after December 31, 2021, if the Closing has not occurred by such date and the terminating party’s breach was not the primary reason

J-41

the Closing failed to occur by such date, (the termination events described in clauses (a)–(d) above, collectively, the “Termination Events”); provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination or common law intentional fraud in the making of any representation or warranty hereunder, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach or fraud. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof. Upon the occurrence of any Termination Event, except as set forth in the proviso to the first sentence of this Section 7, this Subscription Agreement shall be void and of no further effect and any portion of the Purchase Price paid by Subscriber to Company in connection herewith shall promptly (and in any event within two business days) following the Termination Event be returned to Subscriber.

Section 8. Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, in each case arising out of or as a result of, in connection with or relating in any way to this Subscription Agreement and the transactions contemplated by this Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of this Subscription Agreement and the transactions contemplated by this Subscription Agreement, and (c) will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of shares of Class A Common Shares of the Company acquired by any means other than pursuant to this Subscription Agreement.

Section 9. Indemnity.

(a) The Company agrees to indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, and officers, employees, and agents, and each person who controls Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of Subscriber (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by or on behalf of Subscriber expressly for use therein.

(b) Subscriber agrees, severally and not jointly with any person that is a party to the Other Subscription Agreements, to indemnify and hold harmless the Company, its directors, officers, employees and agents, and each person who controls the Company (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Company against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements

J-42

therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing to the Company by or on behalf of Subscriber expressly for use therein. In no event shall the liability of Subscriber be greater in amount than the dollar amount of the net proceeds received by the Company upon the sale of the Subscribed Shares purchased pursuant to this Subscription Agreement giving rise to such indemnification obligation. Each of the Company and Fathom acknowledge and agree that each purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of each of the respective acknowledgments, understandings, agreements, representations and warranties herein (as modified by such notice) made by each of the Company and Fathom as of the time of such purchase.

(c) Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Subscribed Shares purchased pursuant to this Subscription Agreement.

(e) If the indemnification provided under this Section 9 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 9 from any person who was not guilty of such fraudulent misrepresentation. Any contribution pursuant to this Section 9(e) by any seller of Subscribed Shares shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Subscribed Shares pursuant to the Registration Statement. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Subscription Agreement.

J-43

Section 10. Miscellaneous.

(a) All notices, requests, demands, claims, and other communications hereunder shall be in writing. Any notice, request, demand, claim, or other communication hereunder shall be deemed duly given (i) when delivered personally to the recipient, (ii) when sent by electronic mail, on the date and time of transmission to such recipient, provided that no electronic mail is undeliverable or other rejection notice is generated, (iii) one Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid), or (iv) four (4) Business Days after being mailed to the recipient by certified or registered mail, return receipt requested and postage prepaid, and, in each case, addressed to the intended recipient at its address or electronic mail address, as applicable, specified on the signature page hereof or to such electronic mail address or address as subsequently modified by written notice given in accordance with this Section 10(a).

(b) Subscriber acknowledges that the Company, Fathom and the Placement Agents will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company, Fathom and the Placement Agents if it becomes aware that any of the acknowledgments, understandings, agreements, representations and warranties of Subscriber set forth herein are no longer accurate in all material respects. Subscriber acknowledges and agrees that each purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of the acknowledgments, understandings, agreements, representations and warranties herein (as modified by any such notice) by Subscriber as of the time of such purchase. Each of the Company and Fathom acknowledge that Subscriber and Placement Agents will rely on the respective acknowledgments, understandings, agreements, representations and warranties made by each of the Company and Fathom contained in this Subscription Agreement. Prior to the Closing, each of the Company and Fathom agree to promptly notify Subscriber and Placement Agents if they become aware that any of their respective acknowledgments, understandings, agreements, representations and warranties set forth herein are no longer accurate in all material respects.

(c) Each of the Company, Fathom, the Placement Agents, Subscriber and any other person or entity against whom a claim is brought with respect to the purchase of the Subscribed Shares is irrevocably authorized to produce this Subscription Agreement or a copy hereof to any interested party in any administrative or legal proceeding or official inquiry with respect to the matters covered hereby.

(d) Subscriber shall pay all of its own expenses in connection with this Subscription Agreement and the transactions contemplated herein, except as expressly set forth herein.

(e) Neither this Subscription Agreement nor any rights that may accrue to Subscriber hereunder (other than the Subscribed Shares acquired hereunder and Subscriber’s rights under Section 6 hereof) may be transferred or assigned. Neither this Subscription Agreement nor any rights that may accrue to the Company hereunder may be transferred or assigned (provided, that, for the avoidance of doubt, the Company may transfer the Subscription Agreement and its rights hereunder solely in connection with the consummation of the Transactions and exclusively to another entity under the control of, or under common control with, the Company), provided that no such assignment shall relieve the Company of its obligations hereunder if any such assignee fails to perform such obligations. Notwithstanding the foregoing, Subscriber may assign its rights and obligations under this Subscription Agreement to one or more of its affiliates, other investment funds or accounts managed or advised by the investment manager who acts on behalf of Subscriber or, with the Company’s prior written consent, to another person, provided that no such assignment shall relieve Subscriber of its obligations hereunder if any such assignee fails to perform such obligations.

(f) All the agreements, representations and warranties made by each party hereto in this Subscription Agreement shall survive the Closing. For the avoidance of doubt, if for any reason the Closing does not occur prior to the consummation of the Transactions, all representations, warranties, covenants and agreements of the parties hereunder shall survive the consummation of the Transactions and remain in full force and effect.

J-44

(g) The Company may request from Subscriber such additional information as the Company may reasonably deem necessary to evaluate the eligibility of Subscriber to acquire the Subscribed Shares and to register the Subscribed Shares for resale, and Subscriber shall provide such information as may be reasonably requested to the extent readily available and to the extent consistent with Subscriber’s internal policies and procedures; provided that the Company agrees to keep any such information provided by Subscriber confidential except to the extent such disclosure is required in connection with registration of the Subscribed Shares for resale, by law, at the request of the staff of the Commission or under the regulations of the Stock Exchange. Subscriber acknowledges that subject to the conditions set forth in Section 10(t), the Company may file a copy of this Subscription Agreement with the Commission as an exhibit to a periodic report of the Company or a registration statement of the Company.

(h) This Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto.

(i) This Subscription Agreement constitutes the entire agreement, and supersedes all other prior agreements, understandings, representations and warranties, both written and oral, among the parties, with respect to the subject matter hereof.

(j) Except as otherwise provided herein (including the next sentence hereof), this Subscription Agreement is intended for the benefit of the parties hereto and their respective affiliates and their respective heirs, executors, administrators, successors, legal representatives, and permitted assigns and is not for the benefit of, nor may any provision hereof be enforced by, any other person. Except as set forth in Section 10(b), Section 10(c), Section 10(e) and this Section 10(j), this Subscription Agreement shall not confer any rights or remedies upon any person other than the parties hereto, and their respective successor and assigns, and the parties hereto acknowledge that such persons so referenced are third party beneficiaries of this Subscription Agreement for the purposes of, and to the extent of, the rights granted to them, if any, pursuant to the applicable provisions.

(k) The parties hereto acknowledge and agree that (i) this Subscription Agreement is being entered into in order to induce the Company and Fathom to execute and deliver the Transaction Agreement and (ii) irreparable damage would occur in the event that any of the provisions of this Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Subscription Agreement and to enforce specifically the terms and provisions of this Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise. The parties hereto acknowledge and agree that the Company and Fathom shall each be entitled to specifically enforce Subscriber’s obligations to fund the Subscription Amount and the provisions of the Subscription Agreement, in each case, on the terms and subject to the conditions set forth herein. The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 10(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(l) In any dispute arising out of or related to this Subscription Agreement, or any other agreement, document, instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing

J-45

party an appropriate percentage of the costs and attorneys’ fees reasonably incurred and documented by the prevailing party in connection with the adjudication and the enforcement of its rights under this Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby.

(m) If any provision of this Subscription Agreement shall be invalid, illegal or unenforceable, the validity, legality or enforceability of the remaining provisions of this Subscription Agreement shall not in any way be affected or impaired thereby and shall continue in full force and effect.

(n) No failure or delay by a party hereto in exercising any right, power or remedy under this Subscription Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

(o) This Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

(p) This Subscription Agreement shall be governed by, and construed in accordance with, the laws of the State of New York, without regard to the principles of conflicts of laws that would otherwise require the application of the law of any other state.

(q) EACH PARTY AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY HEREBY WAIVES ITS RESPECTIVE RIGHTS TO A TRIAL BY JURY OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OR RELATED TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY IN ANY ACTION, PROCEEDING OR OTHER LITIGATION OF ANY TYPE BROUGHT BY ANY PARTY AGAINST ANY OTHER PARTY OR ANY AFFILIATE OF ANY OTHER SUCH PARTY, WHETHER WITH RESPECT TO CONTRACT CLAIMS, TORT CLAIMS OR OTHERWISE. THE PARTIES AGREE THAT ANY SUCH CLAIM OR CAUSE OF ACTION SHALL BE TRIED BY A COURT TRIAL WITHOUT A JURY. WITHOUT LIMITING THE FOREGOING, THE PARTIES FURTHER AGREE THAT THEIR RESPECTIVE RIGHT TO A TRIAL BY JURY IS WAIVED BY OPERATION OF THIS SECTION AS TO ANY ACTION, COUNTERCLAIM OR OTHER PROCEEDING WHICH SEEKS, IN WHOLE OR IN PART, TO CHALLENGE THE VALIDITY OR ENFORCEABILITY OF THIS SUBSCRIPTION AGREEMENT OR ANY PROVISION HEREOF. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS TO THIS SUBSCRIPTION AGREEMENT.

(r) The parties agree that all disputes, legal actions, suits and proceedings arising out of or relating to this Subscription Agreement must be brought exclusively in the United States District Court for the Southern District of New York, the Supreme Court of the State of New York or the federal courts of the United States of America located in the State of New York (collectively the “Designated Courts”). Each party hereby consents and submits to the exclusive jurisdiction of the Designated Courts. No legal action, suit or proceeding with respect to this Subscription Agreement may be brought in any other forum. Each party hereby irrevocably waives all claims of immunity from jurisdiction, and any objection which such party may now or hereafter have to the laying of venue

J-46

of any suit, action or proceeding in any Designated Court, including any right to object on the basis that any dispute, action, suit or proceeding brought in the Designated Courts has been brought in an improper or inconvenient forum or venue. Each of the parties also agrees that delivery of any process, summons, notice or document to a party hereof in compliance with Section 10(a) of this Subscription Agreement shall be effective service of process for any action, suit or proceeding in a Designated Court with respect to any matters to which the parties have submitted to jurisdiction as set forth above.

(s) This Subscription Agreement may only be enforced against, and any claim, action, suit or other legal proceeding based upon, arising out of, or related to this Subscription Agreement, or the negotiation, execution or performance of this Subscription Agreement, may only be brought against the entities that are expressly named as parties or third party beneficiaries hereto and then only with respect to the specific obligations set forth herein with respect to such party or third party beneficiary. No past, present or future director, officer, employee, incorporator, manager, member, partner, stockholder, affiliate, agent, attorney or other representative of any party hereto or of any affiliate of any party hereto, or any of their successors or permitted assigns, shall have any liability for any obligations or liabilities of any party hereto under this Subscription Agreement or for any claim, action, suit or other legal proceeding based on, in respect of or by reason of the transactions contemplated hereby.

(t) Subscriber hereby consents to the publication and disclosure in any press release issued by the Company, Fathom or any of their respective affiliates, any Form 8-K or Form 6-K or other filing with a governmental authority filed by the Company, Fathom or any of their respective affiliates with the Commission in connection with the execution and delivery of the Transaction Agreement or the transactions contemplated thereby and the Proxy Statement/Consent Solicitation Statement/Prospectus (as defined in the Transaction Agreement) (and, as and to the extent otherwise required by the federal securities laws, exchange rules, the Commission or any other securities authorities or any rules and regulations promulgated thereby, any other documents or communications provided by the Company, Fathom or any of their respective affiliates to any governmental entity or to any securityholders of the Company) of Subscriber’s identity and beneficial ownership of the Subscribed Shares and the nature of Subscriber’s commitments, arrangements and understandings under and relating to this Agreement and, if deemed appropriate by the Company, Fathom or any of their respective affiliates, a copy of this Agreement, all solely to the extent determined by such person or entity to be required by applicable law or any regulation or stock exchange listing requirement. Subscriber will promptly provide any information reasonably requested by the Company, Fathom or any of their respective affiliates for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the Commission). Notwithstanding the foregoing, any such person shall provide to Subscriber a copy of any proposed disclosure relating to Subscriber in accordance with the provisions of this Section 10(t) a reasonable period of time in advance of any publication thereof and shall include such revisions to such proposed disclosure as Subscriber shall reasonably request.

(u) The Company shall, by 9:00 a.m., New York City time, on the second (2nd) Business Day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the Commission a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements and the Transactions. Notwithstanding anything in this Subscription Agreement to the contrary, neither the Company nor Fathom shall (i) publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any press release, without the prior written consent of Subscriber or (ii) publicly disclose the name of Subscriber or any of its affiliates or advisers, or include the name of Subscriber or any of its affiliates or advisers in any filing with the Commission or any regulatory agency or trading market, without the prior written consent of Subscriber, except (A) as required by the federal securities law and (B) to the extent such disclosure is required by law, at the request of the staff of the Commission or regulatory agency or under the regulations of the Stock Exchange. Subscriber will promptly provide any information reasonably requested by the Company, Fathom or any of their respective affiliates for any regulatory application or filing made or approval sought in connection with the Transactions (including filings with the Commission).

J-47

(v) The obligations of Subscriber under this Subscription Agreement are several and not joint with the obligations of any Other Subscriber or any other investor under the Other Subscription Agreements, and Subscriber shall not be responsible in any way for the performance of the obligations of any Other Subscriber under this Subscription Agreement or any Other Subscriber or other investor under the Other Subscription Agreements. The decision of Subscriber to purchase Subscribed Shares pursuant to this Subscription Agreement has been made by Subscriber independently of any Other Subscriber or any other investor and independently of any information, materials, statements or opinions as to the business, affairs, operations, assets, properties, liabilities, results of operations, condition (financial or otherwise) or prospects of the Company, Fathom or any of their respective subsidiaries which may have been made or given by any Other Subscriber or investor or by any agent or employee of any Other Subscriber or investor, and neither Subscriber nor any of its agents or employees shall have any liability to any Other Subscriber or investor (or any other person) relating to or arising from any such information, materials, statements or opinions. Nothing contained herein or in any Other Subscription Agreement, and no action taken by Subscriber or investor pursuant hereto or thereto, shall be deemed to constitute Subscriber and Other Subscribers or other investors as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Subscriber and Other Subscribers or other investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Subscription Agreement and the Other Subscription Agreements. Subscriber acknowledges that no Other Subscriber has acted as agent for Subscriber in connection with making its investment hereunder and no Other Subscriber will be acting as agent of Subscriber in connection with monitoring its investment in the Subscribed Shares or enforcing its rights under this Subscription Agreement. Subscriber shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Subscriber or investor to be joined as an additional party in any proceeding for such purpose.

If the Shares in question were issued in conjunction with rights, options, warrants or units issued pursuant to the Articles on terms that one cannot be transferred without the other, the Directors shall refuse to register the transfer of any such Share without evidence satisfactory to them of the like transfer of such right, option, warrant or unit.

The transferor shall be deemed to remain the holder of a Share until the name of the transferee is entered in the Register of Members.

8 Redemption, Repurchase and Surrender of Shares

8.1 Subject to the provisions of the Statute, and, where applicable, the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or otherwise under Applicable Law, the Company may issue Shares that are to be redeemed or are liable to be redeemed at the option of the Member or the Company. The redemption of such Shares, except Public Shares, shall be effected in such manner and upon such other terms as the Company may, by Special Resolution, determine before the issue of such Shares. With respect to redeeming or repurchasing the Shares:

(a) Members who hold Public Shares are entitled to request the redemption of such Shares in the circumstances described in the Business Combination Article hereof;

K-8

(b) Class B Shares held by the Founders shall be surrendered by the Founders for no consideration to the extent that the Over-Allotment Option is not exercised in full so that the Founders will own 20 per cent of the Company’s issued Shares after the IPO (exclusive of any securities purchased in a private placement simultaneously with the IPO); and

(c) Public Shares shall be repurchased by way of tender offer in the circumstances set out in the Business Combination Article hereof.

8.2 Subject to the provisions of the Statute, and, where applicable, the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or otherwise under Applicable Law, the Company may purchase its own Shares (including any redeemable Shares) in such manner and on such other terms as the Directors may agree with the relevant Member. For the avoidance of doubt, redemptions, repurchases and surrenders of Shares in the circumstances described in the Article above shall not require further approval of the Members.

10 Variation of Rights of Shares

10.1 Subject to Article 3.1, if at any time the share capital of the Company is divided into different classes of Shares, all or any of the rights attached to any class (unless otherwise provided by the terms of issue of the Shares of that class) may, whether or not the Company is being wound up, be varied without the consent of the holders of the issued Shares of that class where such variation is considered by the Directors not to have a material adverse effect upon such rights; otherwise, any such variation shall be made only with the consent in writing of the holders of not less than two thirds of the issued Shares of that class (other than with respect to a waiver of the provisions of the Class B Ordinary Share Conversion Article hereof, which as stated therein shall only require the consent in writing of the holders of a majority of the issued Shares of that class), or with the approval of a resolution passed by a majority of not less than two thirds of the votes cast at a separate meeting of the holders of the Shares of that class. For the avoidance of doubt, the Directors reserve the right, notwithstanding that any such variation may not have a material adverse effect, to obtain consent from the holders of Shares of the relevant class. To any such meeting all the provisions of the Articles relating to general meetings shall apply mutatis mutandis, except that the necessary quorum shall be one person holding or representing by proxy at least one third of the issued Shares of the class and that any holder of Shares of the class present in person or by proxy may demand a poll.

10.2 For the purposes of a separate class meeting, the Directors may treat two or more or all the classes of Shares as forming one class of Shares if the Directors consider that such class of Shares would be affected in the same way by the proposals under consideration, but in any other case shall treat them as separate classes of Shares.

10.3 The rights conferred upon the holders of the Shares of any class issued with preferred or other rights shall not, unless otherwise expressly provided by the terms of issue of the Shares of that class, be deemed to be varied: (i) by the creation or issue of further Shares ranking pari passu therewith or Shares issued with preferred or other rights; or (ii) where the constitutional documents of the Company are amended or new constitutional documents of the Company are adopted, in each case, as a result of the Company undertaking a transfer by way of continuation in a jurisdiction outside the Cayman Islands.

K-9

11 Commission on Sale of Shares

The Company may, in so far as the Statute permits, pay a commission to any person in consideration of his subscribing or agreeing to subscribe (whether absolutely or conditionally) or procuring or agreeing to procure subscriptions (whether absolutely or conditionally) for any Shares. Such commissions may be satisfied by the payment of cash and/or the issue of fully or partly paid-up Shares. The Company may also on any issue of Shares pay such brokerage as may be lawful.

12 Non Recognition of Trusts

The Company shall not be bound by or compelled to recognise in any way (even when notified) any equitable, contingent, future or partial interest in any Share, or (except only as is otherwise provided by the Articles or the Statute) any other rights in respect of any Share other than an absolute right to the entirety thereof in the holder.

13 Lien on Shares

13.1 The Company shall have a first and paramount lien on all Shares (whether fully paid-up or not) registered in the name of a Member (whether solely or jointly with others) for all debts, liabilities or engagements to or with the Company (whether presently payable or not) by such Member or his estate, either alone or jointly with any other person, whether a Member or not, but the Directors may at any time declare any Share to be wholly or in part exempt from the provisions of this Article. The registration of a transfer of any such Share shall operate as a waiver of the Company’s lien thereon. The Company’s lien on a Share shall also extend to any amount payable in respect of that Share.

13.2 The Company may sell, in such manner as the Directors think fit, any Shares on which the Company has a lien, if a sum in respect of which the lien exists is presently payable, and is not paid within fourteen clear days after notice has been received or deemed to have been received by the holder of the Shares, or to the person entitled to it in consequence of the death or bankruptcy of the holder, demanding payment and stating that if the notice is not complied with the Shares may be sold.

13.3 To give effect to any such sale the Directors may authorise any person to execute an instrument of transfer of the Shares sold to, or in accordance with the directions of, the purchaser. The purchaser or his nominee shall be registered as the holder of the Shares comprised in any such transfer, and he shall not be bound to see to the application of the purchase money, nor shall his title to the Shares be affected by any irregularity or invalidity in the sale or the exercise of the Company’s power of sale under the Articles.

13.4 The net proceeds of such sale after payment of costs, shall be applied in payment of such part of the amount in respect of which the lien exists as is presently payable and any balance shall (subject to a like lien for sums not presently payable as existed upon the Shares before the sale) be paid to the person entitled to the Shares at the date of the sale.

14 Call on Shares

14.1 Subject to the terms of the allotment and issue of any Shares, the Directors may make calls upon the Members in respect of any monies unpaid on their Shares (whether in respect of par value or premium), and each Member shall (subject to receiving at least fourteen clear days’ notice specifying the time or times of payment) pay to the Company at the time or times so specified the amount called on the Shares. A call may be revoked or postponed, in whole or in part, as the Directors may determine. A call may be required to be paid by instalments. A person upon whom a call is made shall remain liable for calls made upon him notwithstanding the subsequent transfer of the Shares in respect of which the call was made.

14.2 A call shall be deemed to have been made at the time when the resolution of the Directors authorising such call was passed.

14.3 The joint holders of a Share shall be jointly and severally liable to pay all calls in respect thereof.

K-10

14.4 If a call remains unpaid after it has become due and payable, the person from whom it is due shall pay interest on the amount unpaid from the day it became due and payable until it is paid at such rate as the Directors may determine (and in addition all expenses that have been incurred by the Company by reason of such non-payment), but the Directors may waive payment of the interest or expenses wholly or in part.

14.5 An amount payable in respect of a Share on issue or allotment or at any fixed date, whether on account of the par value of the Share or premium or otherwise, shall be deemed to be a call and if it is not paid all the provisions of the Articles shall apply as if that amount had become due and payable by virtue of a call.

14.6 The Directors may issue Shares with different terms as to the amount and times of payment of calls, or the interest to be paid.

14.7 The Directors may, if they think fit, receive an amount from any Member willing to advance all or any part of the monies uncalled and unpaid upon any Shares held by him, and may (until the amount would otherwise become payable) pay interest at such rate as may be agreed upon between the Directors and the Member paying such amount in advance.

14.8 No such amount paid in advance of calls shall entitle the Member paying such amount to any portion of a Dividend or other distribution payable in respect of any period prior to the date upon which such amount would, but for such payment, become payable.

15 Forfeiture of Shares

15.1 If a call or instalment of a call remains unpaid after it has become due and payable the Directors may give to the person from whom it is due not less than fourteen clear days’ notice requiring payment of the amount unpaid together with any interest which may have accrued and any expenses incurred by the Company by reason of such non-payment. The notice shall specify where payment is to be made and shall state that if the notice is not complied with the Shares in respect of which the call was made will be liable to be forfeited.

15.2 If the notice is not complied with, any Share in respect of which it was given may, before the payment required by the notice has been made, be forfeited by a resolution of the Directors. Such forfeiture shall include all Dividends, other distributions or other monies payable in respect of the forfeited Share and not paid before the forfeiture.

15.3 A forfeited Share may be sold, re-allotted or otherwise disposed of on such terms and in such manner as the Directors think fit and at any time before a sale, re-allotment or disposition the forfeiture may be cancelled on such terms as the Directors think fit. Where for the purposes of its disposal a forfeited Share is to be transferred to any person the Directors may authorise some person to execute an instrument of transfer of the Share in favour of that person.

15.4 A person any of whose Shares have been forfeited shall cease to be a Member in respect of them and shall surrender to the Company for cancellation the certificate for the Shares forfeited and shall remain liable to pay to the Company all monies which at the date of forfeiture were payable by him to the Company in respect of those Shares together with interest at such rate as the Directors may determine, but his liability shall cease if and when the Company shall have received payment in full of all monies due and payable by him in respect of those Shares.

15.5 A certificate in writing under the hand of one Director or Officer that a Share has been forfeited on a specified date shall be conclusive evidence of the facts stated in it as against all persons claiming to be entitled to the Share. The certificate shall (subject to the execution of an instrument of transfer) constitute a good title to the Share and the person to whom the Share is sold or otherwise disposed of shall not be bound to see to the application of the purchase money, if any, nor shall his title to the Share be affected by any irregularity or invalidity in the proceedings in reference to the forfeiture, sale or disposal of the Share.

15.6 The provisions of the Articles as to forfeiture shall apply in the case of non payment of any sum which, by the terms of issue of a Share, becomes payable at a fixed time, whether on account of the par value of the Share or by way of premium as if it had been payable by virtue of a call duly made and notified.

K-11

16 Transmission of Shares

16.1 If a Member dies, the survivor or survivors (where he was a joint holder), or his legal personal representatives (where he was a sole holder), shall be the only persons recognised by the Company as having any title to his Shares. The estate of a deceased Member is not thereby released from any liability in respect of any Share, for which he was a joint or sole holder.

16.2 Any person becoming entitled to a Share in consequence of the death or bankruptcy or liquidation or dissolution of a Member (or in any other way than by transfer) may, upon such evidence being produced as may be required by the Directors, elect, by a notice in writing sent by him to the Company, either to become the holder of such Share or to have some person nominated by him registered as the holder of such Share. If he elects to have another person registered as the holder of such Share he shall sign an instrument of transfer of that Share to that person. The Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution, as the case may be.

16.3 A person becoming entitled to a Share by reason of the death or bankruptcy or liquidation or dissolution of a Member (or in any other case than by transfer) shall be entitled to the same Dividends, other distributions and other advantages to which he would be entitled if he were the holder of such Share. However, he shall not, before becoming a Member in respect of a Share, be entitled in respect of it to exercise any right conferred by membership in relation to general meetings of the Company and the Directors may at any time give notice requiring any such person to elect either to be registered himself or to have some person nominated by him be registered as the holder of the Share (but the Directors shall, in either case, have the same right to decline or suspend registration as they would have had in the case of a transfer of the Share by the relevant Member before his death or bankruptcy or liquidation or dissolution or any other case than by transfer, as the case may be). If the notice is not complied with within ninety days of being received or deemed to be received (as determined pursuant to the Articles), the Directors may thereafter withhold payment of all Dividends, other distributions, bonuses or other monies payable in respect of the Share until the requirements of the notice have been complied with.

17 Class B Ordinary Share Conversion

17.1 The rights attaching to the Class A Shares and Class B Shares shall rank pari passu in all respects, and the Class A Shares and Class B Shares shall vote together as a single class on all matters (subject to the Variation of Rights of Shares Article and the Appointment and Removal of Directors Article hereof) with the exception that the holder of a Class B Share shall have the conversion rights referred to in this Article.

17.2 Class B Shares shall automatically convert into Class A Shares on a one-for-one basis (the “Initial Conversion Ratio”): (a) at any time and from time to time at the option of the holders thereof; and (b) automatically on the day of the closing of a Business Combination.

17.3 Notwithstanding the Initial Conversion Ratio, in the case that additional Class A Shares or any other Equity-linked Securities are issued or deemed issued, by the Company in excess of the amounts offered in the IPO and related to the closing of a Business Combination, all Class B Shares in issue shall automatically convert into Class A Shares at the time of the closing of a Business Combination at an adjusted ratio so that the number of Class A Shares issuable upon conversion of all Class B Shares will equal, in the aggregate, 20 per cent of the sum of: (a) the total number of Class A Shares and Class B Shares issued and outstanding upon completion of the IPO, plus (b) the total number of Class A Shares issued or deemed issued or issuable upon conversion or exercise of any Equity-linked Securities or rights issued, or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A Shares or Equity-linked Securities exercisable for or convertible into Class A Shares issued, deemed issued, or to be issued, to any seller in the initial Business Combination and any private placement warrants or units issued to the Sponsor, its Affiliates or any Director or Officer upon conversion of working capital loans made to the Company.

K-12

17.4 Notwithstanding anything to the contrary contained herein, the foregoing adjustment to the Initial Conversion Ratio may be waived as to any particular issuance or deemed issuance of additional Class A Shares or Equity-linked Securities by the written consent or agreement of holders of a majority of the Class B Shares then in issue consenting or agreeing separately as a separate class in the manner provided in the Variation of Rights of Shares Article hereof.

17.5 The foregoing conversion ratio shall also be adjusted to account for any subdivision (by share subdivision, exchange, capitalisation, rights issue, reclassification, recapitalisation or otherwise) or combination (by share consolidation, exchange, reclassification, recapitalisation or otherwise) or similar reclassification or recapitalisation of the Class A Shares in issue into a greater or lesser number of shares occurring after the original filing of the Articles without a proportionate and corresponding subdivision, combination or similar reclassification or recapitalisation of the Class B Shares in issue.

17.6 Each Class B Share shall convert into its pro rata number of Class A Shares pursuant to this Article. The pro rata share for each holder of Class B Shares will be determined as follows: each Class B Share shall convert into such number of Class A Shares as is equal to the product of 1 multiplied by a fraction, the numerator of which shall be the total number of Class A Shares into which all of the Class B Shares in issue shall be converted pursuant to this Article and the denominator of which shall be the total number of Class B Shares in issue at the time of conversion.

17.7 References in this Article to “converted”, “conversion” or “exchange” shall mean the compulsory redemption without notice of Class B Shares of any Member and, on behalf of such Members, automatic application of such redemption proceeds in paying for such new Class A Shares into which the Class B Shares have been converted or exchanged at a price per Class B Share necessary to give effect to a conversion or exchange calculated on the basis that the Class A Shares to be issued as part of the conversion or exchange will be issued at par. The Class A Shares to be issued on an exchange or conversion shall be registered in the name of such Member or in such name as the Member may direct.

17.8 Notwithstanding anything to the contrary in this Article, in no event may any Class B Share convert into Class A Shares at a ratio that is less than one-for-one.

23.2 A person may participate at a general meeting by conference telephone or other communications equipment by means of which all the persons participating in the meeting can communicate with each other. Participation by a person in a general meeting in this manner is treated as presence in person at that meeting.

23.7 The chairman may, with the consent of a meeting at which a quorum is present (and shall if so directed by the meeting) adjourn the meeting from time to time and from place to place, but no business shall be transacted at any adjourned meeting other than the business left unfinished at the meeting from which the adjournment took place.

23.8 When a general meeting is adjourned for thirty days or more, notice of the adjourned meeting shall be given as in the case of an original meeting. Otherwise it shall not be necessary to give any such notice of an adjourned meeting.

23.9 If, prior to a Business Combination, a notice is issued in respect of a general meeting and the Directors, in their absolute discretion, consider that it is impractical or undesirable for any reason to hold that general meeting at the place, the day and the hour specified in the notice calling such general meeting, the Directors may postpone the general meeting to another place, day and/or hour provided that notice of the place, the day and the hour of the rearranged general meeting is promptly given to all Members. No business shall be transacted at any postponed meeting other than the business specified in the notice of the original meeting.

23.10 When a general meeting is postponed for thirty days or more, notice of the postponed meeting shall be given as in the case of an original meeting. Otherwise it shall not be necessary to give any such notice of a postponed meeting. All proxy forms submitted for the original general meeting shall remain valid for the postponed meeting. The Directors may postpone a general meeting which has already been postponed.

23.11 A resolution put to the vote of the meeting shall be decided on a poll.

23.14 In the case of an equality of votes the chairman shall be entitled to a second or casting vote.

24 Votes of Members

24.1 Subject to any rights or restrictions attached to any Shares, including as set out at Article 31.4, every Member present in any such manner shall have one vote for every Share of which he is the holder.

24.2 In the case of joint holders the vote of the senior holder who tenders a vote, whether in person or by proxy (or, in the case of a corporation or other non-natural person, by its duly authorised representative or proxy), shall be accepted to the exclusion of the votes of the other joint holders, and seniority shall be determined by the order in which the names of the holders stand in the Register of Members.

24.7 A Member holding more than one Share need not cast the votes in respect of his Shares in the same way on any resolution and therefore may vote a Share or some or all such Shares either for or against a resolution and/or abstain from voting a Share or some or all of the Shares and, subject to the terms of the instrument appointing him, a proxy appointed under one or more instruments may vote a Share or some or all of the Shares in respect of which he is appointed either for or against a resolution and/or abstain from voting a Share or some or all of the Shares in respect of which he is appointed.

25 Proxies

25.1 The instrument appointing a proxy shall be in writing and shall be executed under the hand of the appointor or of his attorney duly authorised in writing, or, if the appointor is a corporation or other non-natural person, under the hand of its duly authorised representative. A proxy need not be a Member.

25.2 The Directors may, in the notice convening any meeting or adjourned meeting, or in an instrument of proxy sent out by the Company, specify the manner by which the instrument appointing a proxy shall be deposited and the place and the time (being not later than the time appointed for the commencement of the meeting or adjourned meeting to which the proxy relates) at which the instrument appointing a proxy shall be deposited. In the absence of any such direction from the Directors in the notice convening any meeting or adjourned meeting or in an instrument of proxy sent out by the Company, the instrument appointing a proxy shall be deposited physically at the Registered Office not less than 48 hours before the time appointed for the meeting or adjourned meeting to commence at which the person named in the instrument proposes to vote.

25.4 The instrument appointing a proxy may be in any usual or common form (or such other form as the Directors may approve) and may be expressed to be for a particular meeting or any adjournment thereof or generally until revoked. An instrument appointing a proxy shall be deemed to include the power to demand or join or concur in demanding a poll.

25.5 Votes given in accordance with the terms of an instrument of proxy shall be valid notwithstanding the previous death or insanity of the principal or revocation of the proxy or of the authority under which the proxy was executed, or the transfer of the Share in respect of which the proxy is given unless notice in writing of such death, insanity, revocation or transfer was received by the Company at the Registered Office before the commencement of the general meeting, or adjourned meeting at which it is sought to use the proxy.

26 Corporate Members

26.1 Any corporation or other non-natural person which is a Member may in accordance with its constitutional

K-19

documents, or in the absence of such provision by resolution of its directors or other governing body, authorise such person as it thinks fit to act as its representative at any meeting of the Company or of any class of Members, and the person so authorised shall be entitled to exercise the same powers on behalf of the corporation which he represents as the corporation could exercise if it were an individual Member.

26.2 If a Clearing House (or its nominee(s)), being a corporation, is a Member, it may authorise such persons as it sees fit to act as its representative at any meeting of the Company or at any meeting of any class of Members provided that the authorisation shall specify the number and class of Shares in respect of which each such representative is so authorised. Each person so authorised under the provisions of this Article shall be deemed to have been duly authorised without further evidence of the facts and be entitled to exercise the same rights and powers on behalf of the Clearing House (or its nominee(s)) as if such person was the registered holder of such Shares held by the Clearing House (or its nominee(s)).

27 Shares that May Not be Voted

Shares in the Company that are beneficially owned by the Company shall not be voted, directly or indirectly, at any meeting and shall not be counted in determining the total number of outstanding Shares at any given time.

28 Directors

28.1 There shall be a board of Directors consisting of not less than one person provided however that the Company may by Ordinary Resolution increase or reduce the limits in the number of Directors.

28.2 The Directors shall be divided into three classes: Class I, Class II and Class III. The number of Directors in each class shall be as nearly equal as possible. Upon the adoption of the Articles, the existing Directors shall by resolution classify themselves as Class I, Class II or Class III Directors. The Class I Directors shall stand appointed for a term expiring at the Company’s first annual general meeting, the Class II Directors shall stand appointed for a term expiring at the Company’s second annual general meeting and the Class III Directors shall stand appointed for a term expiring at the Company’s third annual general meeting. Commencing at the Company’s first annual general meeting, and at each annual general meeting thereafter, Directors appointed to succeed those Directors whose terms expire shall be appointed for a term of office to expire at the third succeeding annual general meeting after their appointment. Except as the Statute or other Applicable Law may otherwise require, in the interim between annual general meetings or extraordinary general meetings called for the appointment of Directors and/or the removal of one or more Directors and the filling of any vacancy in that connection, additional Directors and any vacancies in the board of Directors, including unfilled vacancies resulting from the removal of Directors for cause, may be filled by the vote of a majority of the remaining Directors then in office, although less than a quorum (as defined in the Articles), or by the sole remaining Director. All Directors shall hold office until the expiration of their respective terms of office and until their successors shall have been appointed and qualified. A Director appointed to fill a vacancy resulting from the death, resignation or removal of a Director shall serve for the remainder of the full term of the Director whose death, resignation or removal shall have created such vacancy and until his successor shall have been appointed and qualified.

29 Nomination of Directors

29.1 Subject to Article 31.1, nominations of persons for appointment as Directors may be made at an annual general meeting only by:

In no event shall the public announcement of an adjournment or postponement of an annual general meeting, or such adjournment or postponement, commence a new time period or otherwise extend any time period for the giving of a Member’s notice as described herein. Members may nominate a person or persons (as the case may be) for appointment as Directors only as provided in this Article and only for such class(es) as are specified in the notice of annual general meeting as being up for appointment at such annual general meeting.

29.3 Each such notice of a Member’s intent to make a nomination of a Director shall set forth:

29.4 No person shall be eligible for appointment as a Director unless nominated in accordance with the procedures set forth in the Articles. Except as otherwise provided by Applicable Law or the Articles, the chairman or co-chairman of any annual general meeting to appointment Directors or the Directors may, if the facts warrant, determine that a nomination was not made in compliance with the foregoing procedure or if the Member solicits proxies in support of such Member’s nominee(s) without such Member having made the representation required by Article 29.3(c); and if the chairman, co-chairman or the Directors should so determine, it shall be so declared to the annual general meeting, and the defective nomination shall be disregarded. Notwithstanding anything in the Articles to the contrary, unless otherwise required by the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or otherwise under Applicable Law, if a Member intending to make a nomination at an annual general meeting in accordance with this Article does not:

(a) is not and will not become a party to:

(i) any agreement, arrangement or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if appointed as a Director, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the Company; or

(ii) any Voting Commitment that could limit or interfere with such person’s ability to comply, if appointed as a Director, with such person’s duties under Applicable Law;

33.6 The continuing Directors (or a sole continuing Director, as the case may be) may act notwithstanding any vacancy in their body, but if and so long as their number is reduced below the number fixed by or pursuant to the Articles as the necessary quorum of Directors the continuing Directors or Director may act for the purpose of increasing the number of Directors to be equal to such fixed number, or of summoning a general meeting of the Company, but for no other purpose.

33.9 A Director may be represented at any meetings of the board of Directors by a proxy appointed in writing by him. The proxy shall count towards the quorum and the vote of the proxy shall for all purposes be deemed to be that of the appointing Director.

Such right to dissent shall not apply to a Director who voted in favour of such action.

A Director shall be at liberty to vote in respect of any contract or transaction in which he is interested provided that the nature of the interest of any Director in any such contract or transaction shall be disclosed by him at or prior to its consideration and any vote thereon.

35.5 A general notice that a Director is a shareholder, director, officer or employee of any specified firm or company and is to be regarded as interested in any transaction with such firm or company shall be sufficient disclosure for the purposes of voting on a resolution in respect of a contract or transaction in which he has an interest, and after such general notice it shall not be necessary to give special notice relating to any particular transaction.

An Officer may vacate his office at any time if he gives notice in writing to the Company that he resigns his office.

38 No Minimum Shareholding

39 Remuneration of Directors

39.1 The remuneration to be paid to the Directors, if any, shall be such remuneration as the Directors shall determine, provided that no cash remuneration shall be paid to any Director by the Company prior to the consummation of a Business Combination. The Directors shall also, whether prior to or after the consummation of a Business Combination, be entitled to be paid all travelling, hotel and other expenses properly incurred by them in connection with their attendance at meetings of Directors or committees of Directors, or general meetings of the Company, or separate meetings of the holders of any class of Shares or debentures of the Company, or otherwise in connection with the business of the Company or the discharge of their duties as a Director, or to receive a fixed allowance in respect thereof as may be determined by the Directors, or a combination partly of one such method and partly the other.

40 Seal

41 Dividends, Distributions and Reserve

41.1 Subject to the Statute and this Article and except as otherwise provided by the rights attached to any Shares, the Directors may resolve to pay Dividends and other distributions on Shares in issue and authorise payment of the Dividends or other distributions out of the funds of the Company lawfully available therefor. A Dividend shall be deemed to be an interim Dividend unless the terms of the resolution pursuant to which the Directors resolve to pay such Dividend specifically state that such Dividend shall be a final Dividend. No Dividend or other distribution shall be paid except out of the realised or unrealised profits of the Company, out of the share premium account or as otherwise permitted by law.

41.2 Except as otherwise provided by the rights attached to any Shares, all Dividends and other distributions shall be paid according to the par value of the Shares that a Member holds. If any Share is issued on terms providing that it shall rank for Dividend as from a particular date, that Share shall rank for Dividend accordingly.

41.3 The Directors may deduct from any Dividend or other distribution payable to any Member all sums of money (if any) then payable by him to the Company on account of calls or otherwise.

41.4 The Directors may resolve that any Dividend or other distribution be paid wholly or partly by the distribution of specific assets and in particular (but without limitation) by the distribution of shares, debentures, or securities of any other company or in any one or more of such ways and where any difficulty arises in regard to such distribution, the Directors may settle the same as they think expedient and in particular may issue fractional Shares and may fix the value for distribution of such specific assets or any part thereof and may determine that cash payments shall be made to any Members upon the basis of the value so fixed in order to adjust the rights of all Members and may vest any such specific assets in trustees in such manner as may seem expedient to the Directors.

41.5 Except as otherwise provided by the rights attached to any Shares, Dividends and other distributions may be paid in any currency. The Directors may determine the basis of conversion for any currency conversions that may be required and how any costs involved are to be met.

41.6 The Directors may, before resolving to pay any Dividend or other distribution, set aside such sums as they think proper as a reserve or reserves which shall, at the discretion of the Directors, be applicable for any purpose of the Company and pending such application may, at the discretion of the Directors, be employed in the business of the Company.

41.7 Any Dividend, other distribution, interest or other monies payable in cash in respect of Shares may be paid by wire transfer to the holder or by cheque or warrant sent through the post directed to the registered address of the holder or, in the case of joint holders, to the registered address of the holder who is first named on the Register of Members or to such person and to such address as such holder or joint holders may in writing direct. Every such cheque or warrant shall be made payable to the order of the person to whom it is sent. Any one of two or more joint holders may give effectual receipts for any Dividends, other distributions, bonuses, or other monies payable in respect of the Share held by them as joint holders.

41.8 No Dividend or other distribution shall bear interest against the Company.

41.9 Any Dividend or other distribution which cannot be paid to a Member and/or which remains unclaimed after six months from the date on which such Dividend or other distribution becomes payable may, in the

K-28

discretion of the Directors, be paid into a separate account in the Company’s name, provided that the Company shall not be constituted as a trustee in respect of that account and the Dividend or other distribution shall remain as a debt due to the Member. Any Dividend or other distribution which remains unclaimed after a period of six years from the date on which such Dividend or other distribution becomes payable shall be forfeited and shall revert to the Company.

42 Capitalisation

The Directors may at any time capitalise any sum standing to the credit of any of the Company’s reserve accounts or funds (including the share premium account and capital redemption reserve fund) or any sum standing to the credit of the profit and loss account or otherwise available for distribution; appropriate such sum to Members in the proportions in which such sum would have been divisible amongst such Members had the same been a distribution of profits by way of Dividend or other distribution; and apply such sum on their behalf in paying up in full unissued Shares for allotment and distribution credited as fully paid-up to and amongst them in the proportion aforesaid. In such event the Directors shall do all acts and things required to give effect to such capitalisation, with full power given to the Directors to make such provisions as they think fit in the case of Shares becoming distributable in fractions (including provisions whereby the benefit of fractional entitlements accrue to the Company rather than to the Members concerned). The Directors may authorise any person to enter on behalf of all of the Members interested into an agreement with the Company providing for such capitalisation and matters incidental or relating thereto and any agreement made under such authority shall be effective and binding on all such Members and the Company.

43 Books of Account

43.1 The Directors shall cause proper books of account (including, where applicable, material underlying documentation including contracts and invoices) to be kept with respect to all sums of money received and expended by the Company and the matters in respect of which the receipt or expenditure takes place, all sales and purchases of goods by the Company and the assets and liabilities of the Company. Such books of account must be retained for a minimum period of five years from the date on which they are prepared. Proper books shall not be deemed to be kept if there are not kept such books of account as are necessary to give a true and fair view of the state of the Company’s affairs and to explain its transactions.

43.2 The Directors shall determine whether and to what extent and at what times and places and under what conditions or regulations the accounts and books of the Company or any of them shall be open to the inspection of Members not being Directors and no Member (not being a Director) shall have any right of inspecting any account or book or document of the Company except as conferred by Statute or authorised by the Directors or by the Company in general meeting.

43.3 The Directors may cause to be prepared and to be laid before the Company in general meeting profit and loss accounts, balance sheets, group accounts (if any) and such other reports and accounts as may be required by law.

44 Audit

44.1 The Directors may appoint an Auditor of the Company who shall hold office on such terms as the Directors determine.

44.2 Without prejudice to the freedom of the Directors to establish any other committee, if the Shares (or depositary receipts therefor) are listed or quoted on the Designated Stock Exchange, and if required by the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or otherwise under Applicable Law, the Directors shall establish and maintain an Audit Committee as a committee of the Directors and shall adopt a formal written Audit Committee charter and review and assess the adequacy of the formal written charter on an annual basis.

K-29

The composition and responsibilities of the Audit Committee shall comply with the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or otherwise under Applicable Law.

44.3 If the Shares (or depositary receipts therefor) are listed or quoted on the Designated Stock Exchange, the Company shall conduct an appropriate review of all related party transactions on an ongoing basis and shall utilise the Audit Committee for the review and approval of potential conflicts of interest.

44.4 The remuneration of the Auditor shall be fixed by the Audit Committee (if one exists).

44.5 If the office of Auditor becomes vacant by resignation or death of the Auditor, or by his becoming incapable of acting by reason of illness or other disability at a time when his services are required, the Directors shall fill the vacancy and determine the remuneration of such Auditor.

44.6 Every Auditor of the Company shall have a right of access at all times to the books and accounts and vouchers of the Company and shall be entitled to require from the Directors and Officers such information and explanation as may be necessary for the performance of the duties of the Auditor.

44.7 Auditors shall, if so required by the Directors, make a report on the accounts of the Company during their tenure of office at the next annual general meeting following their appointment in the case of a company which is registered with the Registrar of Companies as an ordinary company, and at the next extraordinary general meeting following their appointment in the case of a company which is registered with the Registrar of Companies as an exempted company, and at any other time during their term of office, upon request of the Directors or any general meeting of the Members.

45 Notices

45.1 Notices shall be in writing and may be given by the Company to any Member either personally or by sending it by courier, post, cable, telex, fax or e-mail to him or to his address as shown in the Register of Members (or where the notice is given by e-mail by sending it to the e-mail address provided by such Member). Notice may also be served by Electronic Communication in accordance with the rules and regulations of the Designated Stock Exchange, the Securities and Exchange Commission and/or any other competent regulatory authority or by placing it on the Company’s Website.

45.2 Where a notice is sent by:

(a) courier; service of the notice shall be deemed to be effected by delivery of the notice to a courier company, and shall be deemed to have been received on the third day (not including Saturdays or Sundays or public holidays) following the day on which the notice was delivered to the courier;

(b) post; service of the notice shall be deemed to be effected by properly addressing, pre paying and posting a letter containing the notice, and shall be deemed to have been received on the fifth day (not including Saturdays or Sundays or public holidays in the Cayman Islands) following the day on which the notice was posted;

(c) cable, telex or fax; service of the notice shall be deemed to be effected by properly addressing and sending such notice and shall be deemed to have been received on the same day that it was transmitted;

(e) placing it on the Company’s Website; service of the notice shall be deemed to have been effected one hour after the notice or document was placed on the Company’s Website.

K-30

45.3 A notice may be given by the Company to the person or persons which the Company has been advised are entitled to a Share or Shares in consequence of the death or bankruptcy of a Member in the same manner as other notices which are required to be given under the Articles and shall be addressed to them by name, or by the title of representatives of the deceased, or trustee of the bankrupt, or by any like description at the address supplied for that purpose by the persons claiming to be so entitled, or at the option of the Company by giving the notice in any manner in which the same might have been given if the death or bankruptcy had not occurred.

45.4 Notice of every general meeting shall be given in any manner authorised by the Articles to every holder of Shares carrying an entitlement to receive such notice on the record date for such meeting except that in the case of joint holders the notice shall be sufficient if given to the joint holder first named in the Register of Members and every person upon whom the ownership of a Share devolves by reason of his being a legal personal representative or a trustee in bankruptcy of a Member where the Member but for his death or bankruptcy would be entitled to receive notice of the meeting, and no other person shall be entitled to receive notices of general meetings.

46 Winding Up

46.1 If the Company shall be wound up, the liquidator shall apply the assets of the Company in satisfaction of creditors’ claims in such manner and order as such liquidator thinks fit. Subject to the rights attaching to any Shares, in a winding up:

(a) if the assets available for distribution amongst the Members shall be insufficient to repay the whole of the Company’s issued share capital, such assets shall be distributed so that, as nearly as may be, the losses shall be borne by the Members in proportion to the par value of the Shares held by them; or

(b) if the assets available for distribution amongst the Members shall be more than sufficient to repay the whole of the Company’s issued share capital at the commencement of the winding up, the surplus shall be distributed amongst the Members in proportion to the par value of the Shares held by them at the commencement of the winding up subject to a deduction from those Shares in respect of which there are monies due, of all monies payable to the Company for unpaid calls or otherwise.

46.2 If the Company shall be wound up the liquidator may, subject to the rights attaching to any Shares and with the approval of a Special Resolution of the Company and any other approval required by the Statute, divide amongst the Members in kind the whole or any part of the assets of the Company (whether such assets shall consist of property of the same kind or not) and may for that purpose value any assets and determine how the division shall be carried out as between the Members or different classes of Members. The liquidator may, with the like approval, vest the whole or any part of such assets in trustees upon such trusts for the benefit of the Members as the liquidator, with the like approval, shall think fit, but so that no Member shall be compelled to accept any asset upon which there is a liability.

47 Indemnity and Insurance

47.1 Every Director and Officer (which for the avoidance of doubt, shall not include auditors of the Company), together with every former Director and former Officer (each an “Indemnified Person”) shall be indemnified out of the assets of the Company against any liability, action, proceeding, claim, demand, costs, damages or expenses, including legal expenses, whatsoever which they or any of them may incur as a result of any act or failure to act in carrying out their functions other than such liability (if any) that they may incur by reason of their own actual fraud, wilful neglect or wilful default. No Indemnified Person shall be liable to the Company for any loss or damage incurred by the Company as a result (whether direct or indirect) of the carrying out of their functions unless that liability arises through the actual fraud, wilful neglect or wilful default of such Indemnified Person. No person shall be found to have committed actual fraud, wilful neglect or wilful default under this Article unless or until a court of competent jurisdiction shall have made a finding to that effect.

K-31

47.2 The Company shall advance to each Indemnified Person reasonable attorneys’ fees and other costs and expenses incurred in connection with the defence of any action, suit, proceeding or investigation involving such Indemnified Person for which indemnity will or could be sought. In connection with any advance of any expenses hereunder, the Indemnified Person shall execute an undertaking to repay the advanced amount to the Company if it shall be determined by final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification pursuant to this Article. If it shall be determined by a final judgment or other final adjudication that such Indemnified Person was not entitled to indemnification with respect to such judgment, costs or expenses, then such party shall not be indemnified with respect to such judgment, costs or expenses and any advancement shall be returned to the Company (without interest) by the Indemnified Person.

47.3 The Directors, on behalf of the Company, may purchase and maintain insurance for the benefit of any Director or Officer against any liability which, by virtue of any rule of law, would otherwise attach to such person in respect of any negligence, default, breach of duty or breach of trust of which such person may be guilty in relation to the Company.

(a) submit such Business Combination to its Members for approval; or

(b) provide Members with the opportunity to have their Shares repurchased by means of a tender offer for a per-Share repurchase price payable in cash, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two business days prior to the consummation of such Business Combination, including interest earned on the Trust Account (net of taxes paid or payable, if any), divided by the number of then issued Public Shares, provided that the Company shall not repurchase Public Shares in an amount that would exceed the Redemption Limitation.

If so demanded, the Company shall pay any such redeeming Member, regardless of whether he is voting for or against such proposed Business Combination, a per-Share redemption price payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest earned on the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then issued Public Shares (such redemption price being referred to herein as the “Redemption Price”), but only in the event that the applicable proposed Business Combination is approved and consummated. The Company shall not redeem Public Shares in an amount that would exceed the Redemption Limitation.

(c) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining Members and the Directors, liquidate and dissolve,

subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and other requirements of Applicable Law.

51.8 In the event that any amendment is made to the Articles:

(a) to modify the substance or timing of the Company’s obligation to allow redemption in connection with a Business Combination or redeem 100 per cent of the Public Shares if the Company does not consummate a Business Combination within 24 months from the consummation of the IPO, or such later time as the Members may approve in accordance with the Articles; or

(b) with respect to any other provision relating to Members’ rights or pre-Business Combination activity,

each holder of Public Shares who is not the Sponsor, a Founder, Officer or Director shall be provided with the opportunity to redeem their Public Shares upon the approval or effectiveness of any such amendment at a per-Share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes paid or payable) earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, divided by the number of then outstanding Public Shares. The Company’s ability to provide such redemption in this Article is subject to the Redemption Limitation.

51.11 A Director may vote in respect of a Business Combination in which such Director has a conflict of interest with respect to the evaluation of such Business Combination. Such Director must disclose such interest or conflict to the other Directors.

51.12 As long as the securities of the Company are listed on the New York Stock Exchange, the Company must complete one or more Business Combinations having an aggregate fair market value of at least 80 per cent

K-34

of the assets held in the Trust Account (net of amounts previously disbursed to the Company’s management for taxes and excluding the amount of deferred underwriting discounts held in the Trust Account) at the time of the Company’s signing a definitive agreement in connection with a Business Combination. A Business Combination must not be effectuated with another blank cheque company or a similar company with nominal operations.

51.13 The Company may enter into a Business Combination with a target business that is Affiliated with the Sponsor, a Founder, a Director or an Officer. In the event the Company seeks to consummate a Business Combination with a target that is Affiliated with the Sponsor, a Founder, a Director or an Officer, the Company, or a committee of Independent Directors, will obtain an opinion from an independent investment banking firm or another valuation or appraisal firm that regularly renders fairness opinions on the type of target business the Company is seeking to acquire that is a member of the United States Financial Industry Regulatory Authority or an independent accounting firm that such a Business Combination is fair to the Company from a financial point of view.

52 Certain Tax Filings

Each Tax Filing Authorised Person and any such other person, acting alone, as any Director shall designate from time to time, are authorised to file IRS forms SS-4, W-8 BEN, W-8 IMY, W-9, 8832 and 2553 and such other similar tax forms as are customary to file with any US state or federal governmental authorities or foreign governmental authorities in connection with the formation, activities and/or elections of the Company and such other tax forms as may be approved from time to time by any Director or Officer. The Company further ratifies and approves any such filing made by any Tax Filing Authorised Person or such other person prior to the date of the Articles.

53 Business Opportunities

53.1 To the fullest extent permitted by Applicable Law, no individual serving as a Director or an Officer (“Management”) shall have any duty, except and to the extent expressly assumed by contract, to refrain from engaging directly or indirectly in the same or similar business activities or lines of business as the Company. To the fullest extent permitted by Applicable Law, the Company renounces any interest or expectancy of the Company in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for Management, on the one hand, and the Company, on the other. Except to the extent expressly assumed by contract, to the fullest extent permitted by Applicable Law, Management shall have no duty to communicate or offer any such corporate opportunity to the Company and shall not be liable to the Company or its Members for breach of any fiduciary duty as a Member, Director and/or Officer solely by reason of the fact that such party pursues or acquires such corporate opportunity for itself, himself or herself, directs such corporate opportunity to another person, or does not communicate information regarding such corporate opportunity to the Company.

53.2 Except as provided elsewhere in this Article, the Company hereby renounces any interest or expectancy of the Company in, or in being offered an opportunity to participate in, any potential transaction or matter which may be a corporate opportunity for both the Company and Management, about which a Director and/or Officer who is also a member of Management acquires knowledge.

53.3 To the extent a court might hold that the conduct of any activity related to a corporate opportunity that is renounced in this Article to be a breach of duty to the Company or its Members, the Company hereby waives, to the fullest extent permitted by Applicable Law, any and all claims and causes of action that the Company may have for such activities. To the fullest extent permitted by Applicable Law, the provisions of this Article apply equally to activities conducted in the future and that have been conducted in the past.

(c) This Backstop Subscription Agreement has been duly authorized, executed and delivered by the Company, and assuming the due authorization, execution and delivery of the same by Subscriber and Fathom, this Backstop Subscription Agreement constitutes the valid and legally binding obligation of the Company, enforceable against the Company in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.

(d) The execution and delivery of this Backstop Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by the Company with all of the provisions of this Backstop Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Company pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject; (ii) the organizational documents of the Company; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over the Company or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Company Material Adverse Effect.

(e) The Company is not required to obtain any consent, waiver, authorization or order of, give any notice to, or make any filing or registration with, any court or other federal, state, local or other governmental authority, self-regulatory organization (including a national securities exchange such as the New York Stock Exchange (such national securities exchange, the “Stock Exchange”)) or other person in connection with the execution, delivery and performance of this Backstop Subscription Agreement (including, without limitation, the issuance of the Subscribed Shares), other than (i) filings required by applicable state securities laws, (ii), the filing of the Registration Statement pursuant to Section 6 below, (iii) those required by the Stock Exchange, including with respect to obtaining stockholder approval, (iv) those required to consummate the Transactions as provided under

L-4

the Transaction Agreement, (v) the filing of notification under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, if applicable, and (vi) other filings, the failure of which to obtain would not reasonably be expected to have a Company Material Adverse Effect.

(f) Except for such matters as have not had and would not reasonably be expected to have a Company Material Adverse Effect, there is no (i) suit, action, investigation, proceeding or arbitration before a governmental authority or arbitrator pending, or, to the knowledge of the Company, threatened in writing against the Company or any of its directors or officers in their capacities as such or (ii) judgment, decree, injunction, ruling or order of any governmental authority or arbitrator outstanding against the Company or any of its directors or officers in their capacities as such.

Except as disclosed in the SEC Documents, as of the date hereof, there is no suit, action, proceeding or investigation pending or, to the knowledge of the Company, threatened against the Company by NYSE or the SEC, respectively, to prohibit or terminate the listing of the Company’s shares on NYSE or to deregister the shares under the Exchange Act.

(c) The execution and delivery of this Backstop Subscription Agreement, the issuance and sale of the Subscribed Shares and the compliance by Fathom with all of the provisions of this Backstop Subscription Agreement and the consummation of the transactions contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or

L-6

imposition of any lien, charge or encumbrance upon any of the property or assets of Fathom pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which Fathom is a party or by which Fathom is bound or to which any of the property or assets of Fathom is subject; (ii) the organizational documents of Fathom; or (iii) any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over Fathom or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a Fathom Material Adverse Effect.

For purposes of this Backstop Subscription Agreement, a “Subscriber Material Adverse Effect” means an event, change, development, occurrence, condition or effect with respect to Subscriber that would reasonably be expected to have a material adverse effect on Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase of the Subscribed Shares.

(d) Subscriber (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), (7) (8), (9), (12) or (13) under the Securities Act) satisfying the applicable requirements set forth on Annex A, (ii) is acquiring the Subscribed Shares only for its own account and not for the account of others, or if Subscriber is subscribing for the Subscribed Shares as a fiduciary or agent for one or more investor accounts, each owner of such account is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act) or an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3), (7) (8), (9), (12) or (13) under the Securities Act), and Subscriber has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Subscribed Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and has provided the Company with the requested information on Annex A following the signature page hereto).

Subscriber acknowledges and agrees that the Subscribed Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”) until at least one year from the Closing Date. Subscriber understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the Subscribed Shares.

Subscriber acknowledges that certain information provided to Subscriber was based on projections, and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projections.

(g) In making its decision to purchase the Subscribed Shares, Subscriber has relied solely upon independent investigation made by Subscriber. Subscriber acknowledges and agrees that Subscriber has received such information as Subscriber deems necessary in order to make an investment decision with respect to the Subscribed Shares, including with respect to the Company and its subsidiaries and the Transactions. Subscriber represents and agrees that Subscriber and Subscriber’s professional advisor(s), if any, have had the opportunity to ask such questions, receive such answers and obtain such information as Subscriber and such undersigned’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Subscribed Shares. Without limiting the generality of the foregoing, Subscriber acknowledges that it has received (or in the case of documents filed with the Commission, had access to) the Company’s filings with the Commission and any disclosure documents provided by or on behalf of the Company or Fathom in connection with this Subscription. Subscriber acknowledges that no statement or printed material contrary to any such disclosure documents has been made or given to Subscriber by or on behalf of the Company or Fathom.

(h) Subscriber became aware of this offering of the Subscribed Shares solely by means of direct contact between Subscriber and the Company, Fathom, or their respective representatives or affiliates, and the Subscribed Shares were offered to Subscriber solely by direct contact between Subscriber and the Company, Fathom or their respective affiliates. Subscriber did not become aware of this offering of the Subscribed Shares, nor were the Subscribed Shares offered to Subscriber, by any other means.

(i) Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed Shares.

L-8

(j) Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares and determined that the Subscribed Shares are a suitable investment for Subscriber and that Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total loss of Subscriber’s investment in the Company. Subscriber acknowledges specifically that a possibility of total loss exists.

(k) Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Subscribed Shares or made any findings or determination as to the fairness of this investment.

(l) Subscriber is not, and is not owned or controlled by or acting on behalf of (in connection with the Transactions), a Sanctioned Person. Subscriber is not a non-U.S. shell bank or providing banking services to a non-U.S. shell bank. Subscriber represents that if it is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.), as amended by the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), that Subscriber maintains, either directly or through the use of a third-party administrator, policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act.

Part 800.244) will acquire a substantial interest in the Company as a result of the purchase and sale of Subscribed Shares hereunder such that a declaration to the Committee on Foreign Investment in the United States would be mandatory under 31 C.F.R. Part 800.401, and no foreign person will have control (as defined in 31 C.F.R.

Section 6. Registration of Subscribed Shares.

(a) The Company agrees that the Company will file with the Commission (at the Company’s sole cost and expense) a registration statement registering the resale of the Subscribed Shares (the “Registration Statement”) no later than (30) calendar days after the Closing Date, and the Company shall use its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) sixty (60) calendar days after the filing thereof (or, in the event the Commission reviews and has written comments to the Registration Statement, the ninetieth (90th) calendar day following the filing thereof) and (ii) the tenth (10th) business day after the date the Company is notified (orally or in writing, whichever is earlier) by the Commission that the Registration Statement will not be “reviewed” or will not be subject to further review ((i) and (ii) collectively, the “Effectiveness Deadline”); provided, that if such day falls on a Saturday, Sunday or other day that the Commission is closed for business, the Effectiveness Deadline shall be extended to the next Business Day on which the Commission is open for business. The Company will use its commercially reasonable efforts to provide a draft of the Registration Statement to the undersigned for review and comment at least two (2) Business Days in advance of filing the Registration Statement; provided that, for the avoidance of doubt, in no event shall the Company be required to delay or postpone the filing of such Registration Statement as a result of or in connection with Subscriber’s review. Unless otherwise agreed to in writing by Subscriber, Subscriber shall not be identified as a statutory underwriter in the Registration Statement unless requested by the Commission or another regulatory agency; provided, that if the Commission or another regulatory agency requests that a Subscriber be identified as a statutory underwriter in the Registration Statement, Subscriber will have the opportunity to withdraw from the Registration Statement prior to the Registration Statement becoming effective upon its prompt written request to the Company. Notwithstanding the foregoing, if the Commission prevents the Company from including any or all of the shares proposed to be registered under the Registration Statement due to limitations on the use of Rule 415 of the Securities Act for the resale of the Subscribed Shares by the applicable stockholders or otherwise, such Registration Statement shall register for resale such number of Subscribed Shares which is equal to the maximum number of Subscribed Shares as is permitted by the Commission. In such event, the number of Subscribed Shares to be registered for each selling stockholder named in the Registration Statement shall be reduced pro rata among all such selling stockholders and as promptly as practicable after being permitted to register additional Subscribed Shares under Rule 415 under the Securities Act, the Company shall amend the Registration Statement or file a new Registration Statement to register such additional Subscribed Shares that were not included in the initial Registration Statement and cause such amendment or Registration Statement to become effective as promptly as practicable. The Company agrees that, except for such times as the Company is permitted hereunder to suspend the use of the prospectus forming part of a Registration Statement, the Company will use its commercially reasonable efforts to cause such Registration Statement to remain effective with respect to Subscriber until the earlier of (i) two years from the issuance of the Subscribed Shares, (ii) the date on which all of the Subscribed Shares shall have been sold, or (iii) on the first date on which the undersigned can sell all of its Subscribed Shares (or shares received in exchange therefor) under Rule 144 without limitation as to the manner of sale or the amount of such securities that may be sold and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable). If requested by Subscriber, the Company shall use its commercially reasonable efforts to (i) cause the removal of the restrictive legends from any Subscribed Shares being sold under the Registration Statement or pursuant to Rule 144 at the time of sale of such Registrable Securities (as defined below) and, at the request of a Holder (as defined below), cause the removal of all restrictive legends from any Registrable Securities held by such Holder

L-10

that may be sold by such Holder without restriction under Rule 144, including without limitation, any volume and manner of sale restrictions, and (ii) cause its legal counsel to deliver an opinion, if necessary, to the transfer agent in connection with the instruction under subclause (i) to the effect that the removal of such restrictive legends in such circumstances may be effected under the Securities Act, in each case upon the receipt of customary representations and other documentation, if any, from the Holder as reasonably requested by the Company, its counsel or the transfer agent, establishing that restrictive legends are no longer required. Any costs related to the foregoing, including fees of the transfer agent, DTC and legal counsel to the Company shall be borne by the Company. The Company will use commercially reasonable efforts to make and keep public information available (as those terms are understood and defined in Rule 144) and file all reports, and provide all customary and reasonable cooperation, necessary to enable Holder to resell Registrable Securities pursuant to the Registration Statement or Rule 144, as applicable, qualify the Registrable Securities for listing on the applicable stock exchange on which the Company’s Class A Common Shares are then listed and update or amend the Registration Statement as necessary to include Registrable Securities. “Registrable Securities” shall mean, as of any date of determination, the Subscribed Shares and any other equity security issued or issuable with respect to the Subscribed Shares by way of share split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, provided, however, that such securities shall cease to be Registrable Securities at the earliest of (A) three (3) years, (B) the date all Subscribed Shares held by a Holder may be sold by such Holder without volume or manner of sale limitations pursuant to Rule 144 and without the requirement for the Company to be in compliance with the current public information required under Rule 144(c)(1) (or Rule 144(i)(2), if applicable), (C) the date on which such securities have actually been sold by a Holder, or (D) when such securities shall have ceased to be outstanding. “Holder” shall mean Subscriber or any affiliate of Subscriber to which the rights under this Section 6 shall have been assigned. The Company’s obligations to include the Subscribed Shares in the Registration Statement are contingent upon Subscriber furnishing in writing to the Company such information regarding Subscriber, the securities of the Company held by Subscriber and the intended method of disposition of the Subscribed Shares as shall be reasonably requested by the Company to effect the registration of the Subscribed Shares, and Subscriber shall execute such documents in connection with such registration as the Company may reasonably request that are customary of a selling stockholder in similar situations, including providing that the Company shall be entitled to postpone and suspend the effectiveness or use of the Registration Statement during any customary blackout or similar period or as permitted hereunder; provided that Subscriber shall not in connection with the foregoing be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer Subscriber Shares. In the case of the registration effected by the Company pursuant to this Backstop Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. Subscriber shall not be entitled to use the Registration Statement for an underwritten offering of Subscribed Shares. Notwithstanding anything to the contrary contained herein, the Company may delay or postpone filing of such Registration Statement, and from time to time require Subscriber not to sell under the Registration Statement or suspend the use or effectiveness of any such Registration Statement if it determines that in order for the registration statement to not contain a material misstatement or omission, an amendment thereto would be needed, or if, in the reasonable determination of the Company’s board of directors, upon advice of legal counsel, such filing or use could materially affect a bona fide business or financing transaction of the Company or would require premature disclosure of information that could materially adversely affect the Company (each such circumstance, a “Suspension Event”); provided, that, (w) the Company shall not so delay filing or so suspend the use of the Registration Statement for a period of more than sixty (60) consecutive days or more than two (2) times in any three hundred sixty (360) day period and (x) the Company shall use commercially reasonable efforts to make such registration statement available for the sale by the undersigned of such securities as soon as practicable thereafter.

L-11

(b) In the case of the registration effected by the Company pursuant to this Backstop Subscription Agreement, the Company shall, upon reasonable request, inform Subscriber as to the status of such registration. At its expense the Company shall:

(i) advise Subscriber, as expeditiously as possible:

(i) when a Registration Statement or any amendment thereto has been filed with the Commission;

(ii) after it shall receive notice or obtain knowledge thereof, of the issuance by the Commission of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose;

(iii) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Subscribed Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and

(iv) subject to the provisions in this Backstop Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in light of the circumstances under which they were made) not misleading.

(ii) use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable;

(iii) upon the occurrence of any event contemplated in Section 6(b)(i)(iv) above, except for such times as the Company is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a Registration Statement, the Company shall use its commercially reasonable efforts to as soon as reasonably practicable prepare a post-effective amendment to such Registration Statement or a supplement to the related prospectus, or file any other required document so that, as thereafter delivered to purchasers of the Subscribed Shares included therein, such prospectus will not include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading;

(iv) use its commercially reasonable efforts to allow Subscriber to review disclosure regarding Subscriber in the Registration Statement; and

(v) otherwise, in good faith, cooperate reasonably with, and take such customary actions as may reasonably be requested by Subscriber, consistent with the terms of this Backstop Subscription Agreement, in connection with the registration of the Subscribed Shares.

(c) Upon receipt of any written notice from the Company of the occurrence of any Suspension Event during the period that the Registration Statement is effective or if as a result of a Suspension Event the Registration Statement or related prospectus contains any untrue statement of a material fact or omits to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made (in the case of the prospectus) not misleading, the undersigned agrees that (i) it will immediately discontinue offers and sales of the Subscribed Shares under the Registration Statement (excluding, for the avoidance of doubt, sales conducted pursuant to Rule 144) until the undersigned receives copies of a supplemental or amended prospectus (which the Company agrees to promptly prepare) that corrects the misstatement(s) or omission(s) referred to above and receives notice that any post-effective amendment has become effective or unless otherwise notified by the Company that it may resume such offers and sales, and (ii) it will maintain the confidentiality of any information included in such written notice delivered by the Company unless otherwise required by law, subpoena or regulatory request or requirement. If so directed by the Company, the undersigned will deliver to the Company, or in the undersigned’s sole discretion destroy, all copies of the

L-12

prospectus covering the Subscribed Shares in the undersigned’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Subscribed Shares shall not apply (w) to the extent the undersigned is required to retain a copy of such prospectus (A) in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or (B) in accordance with a bona fide pre-existing document retention policy or (x) to copies stored electronically on archival servers as a result of automatic data back-up.

Section 7. Termination. This Backstop Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earliest to occur of (a) such date and time as the Transaction Agreement is validly terminated in accordance with its terms without being consummated, (b) upon the mutual written agreement of all parties hereto to terminate this Backstop Subscription Agreement, (c) if, on the Closing Date of the Transactions, (i) any of the conditions to Closing set forth in Section 2 of this Backstop Subscription Agreement have not been satisfied as of the time required hereunder to be so satisfied or waived by the party entitled to grant such waiver and, as a result thereof, the transactions contemplated by this Backstop Subscription Agreement are not consummated or (ii) the Minimum Cash Condition is satisfied without regard or giving effect to this Backstop Subscription Agreement (including any purchase of Subcribed Shares by Subscriber) or (d) by written notice from Subscriber or any other party given anytime on or after December 31, 2021, if the Closing has not occurred by such date and the terminating party’s breach was not the primary reason the Closing failed to occur by such date, (the termination events described in clauses (a)–(d) above, collectively, the “Termination Events”); provided, that nothing herein will relieve any party from liability for any willful breach hereof prior to the time of termination or common law intentional fraud in the making of any representation or warranty hereunder, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from such breach or fraud. The Company shall notify Subscriber of the termination of the Transaction Agreement promptly after the termination thereof. Upon the occurrence of any Termination Event, except as set forth in the proviso to the first sentence of this Section 7, this Backstop Subscription Agreement shall be void and of no further effect and any portion of the Purchase Price paid by Subscriber to Company in connection herewith shall promptly (and in any event within two business days) following the Termination Event be returned to Subscriber.

Section 8. Trust Account Waiver. Subscriber hereby acknowledges that the Company has established a trust account (the “Trust Account”) containing the proceeds of its initial public offering (the “IPO”) and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time thereon) for the benefit of the Company’s public stockholders and certain other parties (including the underwriters of the IPO). For and in consideration of the Company entering into this Backstop Subscription Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Subscriber hereby (a) agrees that it does not now and shall not at any time hereafter have any right, title, interest or claim of any kind in or to any assets held in the Trust Account, and shall not make any claim against the Trust Account, in each case arising out of or as a result of, in connection with or relating in any way to this Backstop Subscription Agreement and the transactions contemplated by this Backstop Subscription Agreement, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released Claims”), (b) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future as a result of, or arising out of this Backstop Subscription Agreement and the transactions contemplated by this Backstop Subscription Agreement, and (c) will not seek recourse against the Trust Account for any reason whatsoever; provided, however, that nothing in this Section 8 shall be deemed to limit any Subscriber’s right to distributions from the Trust Account in accordance with the Company’s amended and restated certificate of incorporation in respect of shares of Class A Common Shares of the Company acquired by any means other than pursuant to this Backstop Subscription Agreement.

L-13

Section 9. Indemnity.

(a) The Company agrees to indemnify and hold harmless, to the extent permitted by law, Subscriber, its directors, and officers, employees, and agents, and each person who controls Subscriber (within the meaning of the Securities Act or the Exchange Act) and each affiliate of Subscriber (within the meaning of Rule 405 under the Securities Act) from and against any and all losses, claims, damages, liabilities and expenses (including, without limitation, any reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) caused by any untrue or alleged untrue statement of material fact contained in any Registration Statement, prospectus included in any Registration Statement or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as the same are caused by or contained in any information furnished in writing to the Company by or on behalf of Subscriber expressly for use therein.

(b) Subscriber severally but not jointly agrees to indemnify and hold harmless the Company, its directors, officers, employees and agents, and each person who controls the Company (within the meaning of the Securities Act or the Exchange Act) and each affiliate of the Company against any losses, claims, damages, liabilities and expenses (including, without limitation, reasonable attorneys’ fees and expenses incurred in connection with defending or investigating any such action or claim) resulting from any untrue statement of material fact contained in the Registration Statement, prospectus or preliminary prospectus or any amendment thereof or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information or affidavit so furnished in writing to the Company by or on behalf of Subscriber expressly for use therein. In no event shall the liability of either of CORE Fund I or CORE Fund I Parallel be greater in amount than the dollar amount of the net proceeds received by the Company upon the sale of the portion of the Subscribed Shares purchased by CORE Fund I or CORE Fund I Parallel, respectively, pursuant to this Backstop Subscription Agreement giving rise to such indemnification obligation. Each of the Company and Fathom acknowledge and agree that each purchase by Subscriber of Subscribed Shares from the Company will constitute a reaffirmation of each of the respective acknowledgments, understandings, agreements, representations and warranties herein (as modified by such notice) made by each of the Company and Fathom as of the time of such purchase.

(c) Any person entitled to indemnification herein shall (1) give prompt written notice to the indemnifying party of any claim with respect to which it seeks indemnification (provided that the failure to give prompt notice shall not impair any person’s right to indemnification hereunder to the extent such failure has not prejudiced the indemnifying party) and (2) permit such indemnifying party to assume the defense of such claim with counsel reasonably satisfactory to the indemnified party. If such defense is assumed, the indemnifying party shall not be subject to any liability for any settlement made by the indemnified party without its consent. An indemnifying party who elects not to assume the defense of a claim shall not be obligated to pay the fees and expenses of more than one counsel for all parties indemnified by such indemnifying party with respect to such claim, unless in the reasonable judgment of legal counsel to any indemnified party a conflict of interest exists between such indemnified party and any other of such indemnified parties with respect to such claim. No indemnifying party shall, without the consent of the indemnified party, consent to the entry of any judgment or enter into any settlement which cannot be settled in all respects by the payment of money (and such money is so paid by the indemnifying party pursuant to the terms of such settlement) or which settlement does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation.

(d) The indemnification provided for under this Backstop Subscription Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of the indemnified party or any officer, director, employee, agent, affiliate or controlling person of such indemnified party and shall survive the transfer of the Subscribed Shares purchased pursuant to this Backstop Subscription Agreement.

L-14

(e) If the indemnification provided under this Section 9 from the indemnifying party is unavailable or insufficient to hold harmless an indemnified party in respect of any losses, claims, damages, liabilities and expenses referred to herein, then the indemnifying party, in lieu of indemnifying the indemnified party, shall contribute to the amount paid or payable by the indemnified party as a result of such losses, claims, damages, liabilities and expenses in such proportion as is appropriate to reflect the relative fault of the indemnifying party and the indemnified party, as well as any other relevant equitable considerations. The relative fault of the indemnifying party and indemnified party shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, was made by, or relates to information supplied by or on behalf of, such indemnifying party or indemnified party, and the indemnifying party’s and indemnified party’s relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or payable by a party as a result of the losses or other liabilities referred to above shall be deemed to include, subject to the limitations set forth above, any legal or other fees, charges or expenses reasonably incurred by such party in connection with any investigation or proceeding. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution pursuant to this Section 9 from any person who was not guilty of such fraudulent misrepresentation. Any contribution pursuant to this Section 9(e) by any seller of Subscribed Shares shall be limited in amount to the amount of net proceeds received by such seller from the sale of such Subscribed Shares pursuant to this Backstop Subscription Agreement. Any contribution by either of CORE Fund I or CORE Fund I Parallel pursuant to this Section 9(e) shall be limited in amount to the amount of net proceeds received by the Company upon the sale of the portion of the Subscribed Shares purchased by CORE Fund I or CORE Fund I Parallel, respectively, pursuant to this Backstop Subscription Agreement. Notwithstanding anything to the contrary herein, in no event will any party be liable for consequential, special, exemplary or punitive damages in connection with this Backstop Subscription Agreement.

(k) The parties hereto acknowledge and agree that (i) this Backstop Subscription Agreement is being entered into in order to induce the Company and Fathom to execute and deliver the Transaction Agreement and (ii) irreparable damage would occur in the event that any of the provisions of this Backstop Subscription Agreement were not performed in accordance with their specific terms or were otherwise breached and that money or other legal remedies would not be an adequate remedy for such damage. It is accordingly agreed that the parties shall be entitled to equitable relief, including in the form of an injunction or injunctions to prevent breaches or threatened breaches of this Backstop Subscription Agreement and to enforce specifically the terms and provisions of this Backstop Subscription Agreement, this being in addition to any other remedy to which such party is entitled at law, in equity, in contract, in tort or otherwise.

The parties hereto further acknowledge and agree: (x) to waive any requirement for the security or posting of any bond in connection with any such equitable remedy; (y) not to assert that a remedy of specific enforcement pursuant to this Section 10(k) is unenforceable, invalid, contrary to applicable law or inequitable for any reason; and (z) to waive any defenses in any action for specific performance, including the defense that a remedy at law would be adequate.

(l) In any dispute arising out of or related to this Backstop Subscription Agreement, or any other agreement, document, instrument or certificate contemplated hereby, or any transactions contemplated hereby or thereby, the applicable adjudicating body shall award to the prevailing party, if any, the costs and attorneys’ fees reasonably incurred by the prevailing party in connection with the dispute and the enforcement of its rights under this Backstop Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby and, if the adjudicating body determines a party to be the prevailing party under circumstances where the prevailing party won on some but not all of the claims and counterclaims, the adjudicating body may award the prevailing party an appropriate percentage of the costs and attorneys’ fees reasonably incurred and documented by the prevailing party in connection with the adjudication and the enforcement of its rights under this Backstop Subscription Agreement or any other agreement, document, instrument or certificate contemplated hereby or thereby.

No single or partial exercise of any right, power or remedy under this Backstop Subscription Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Backstop Subscription Agreement shall entitle the party receiving such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

(o) This Backstop Subscription Agreement may be executed and delivered in one or more counterparts (including by facsimile or electronic mail or in .pdf) and by different parties in separate counterparts, with the same effect as if all parties hereto had signed the same document. All counterparts so executed and delivered shall be construed together and shall constitute one and the same agreement.

Reference is made to that certain Business Combination Agreement of even date herewith (as the same may be amended, restated or amended and restated from time to time in accordance with its terms, “Business Combination Agreement”), by and among Altimar Acquisition Corp.

Unless otherwise expressly provided herein, capitalized terms shall have the respective meanings assigned to them in the Business Combination Agreement.

Pursuant to Article 17.2 of Buyer’s Memorandum and Articles of Association, outstanding Buyer Class B ordinary shares, par value of US$0.0001 per share (“Cayman Class B Shares”), shall automatically convert into Buyer Class A ordinary shares, par value of US$0.0001 per share (“Cayman Class A Shares”), on a one- for-one basis automatically on the day of the closing of a Business Combination (as defined in the Buyer’s Articles and Memorandum of Association as in effect on the date hereof (the “Cayman Charter”)), subject to certain anti-dilution adjustments if additional Cayman Class A Shares or any other Equity-linked Securities (as defined in the Cayman Charter) are issued or deemed issued in excess of the amounts offered in Buyer’s initial public offering and related to the closing of a Business Combination (as defined in the Cayman Charter), which anti-dilution adjustments may be waived by the holders of a majority of the outstanding Cayman Class B Shares, consenting as a separate class.

M-1

Section 2.02 of the Business Combination Agreement contemplates that following the Pre-Closing Reorganization but prior to the consummation of the PIPE Investment, Buyer will domesticate as a Delaware corporation in accordance with Section 388 of the DGCL and de-register as a Cayman Islands exempted company (the “Domestication”). As a result of the Domestication, each then issued and outstanding Cayman Class B Share will become a share of Class C Common Stock, par value $0.0001 (“Altimar Class C Common Stock”), which shares of Class C Common Stock shall convert into shares of Altimar Class A Common Stock, par value $0.0001 (“Altimar Class A Common Stock”), on a one-for-one basis automatically on the day of the closing of a Business Combination (as defined in the Altimar Charter, which will be filed by Buyer with the Secretary of State of the State of Delaware in connection with the Domestication (the “Delaware Charter”, and together with the Cayman Charter, the “Charter Documents”)), subject to certain anti-dilution adjustments if additional shares of Altimar Class A Common Stock or any other Equity-linked Securities (as defined in the Delaware Charter) are issued or deemed issued in excess of the amounts offered in Buyer’s initial public offering and related to the closing of a Business Combination (as defined in the Delaware Charter), which anti-dilution adjustments may be waived by the holders of a majority of the outstanding shares of Altimar Class C Common Stock.

1. Effective upon and subject to the Closing, Sponsor, as holder of a majority of the outstanding Cayman Class B Shares (and as prospective holder of a majority of the shares of Altimar Class C Common Stock, which will result from the Domestication), pursuant to Article 17.4 of the Cayman Charter and Section 4.3(f)(iii) of the Delaware Charter irrevocably waives all of the anti-dilution adjustments set forth in each of Article 17.3 of Cayman Charter and Section 4.3(f)(ii) of the Delaware Charter in connection with the transactions contemplated by the Business Combination Agreement (the “Anti-dilution Waiver”).

2. Effective upon and subject to the Closing, and without duplication of the forfeiture of Cayman Class B Ordinary Shares contemplated in Section 2.02 of the Business Combination Agreement, Sponsor shall irrevocably automatically forfeit and surrender, for no additional consideration and without any further action on the part of any other Person, the Forfeited Shares (as defined below), which would otherwise be held by the Sponsor as a result of the automatic conversion of shares of Altimar Class C Common Stock after giving effect to the Closing, the Domestication and the Anti-dilution Waiver (the “Forfeiture”).

3. Effective upon and subject to the Closing, Buyer acknowledges the Anti-dilution Waiver and agrees to give effect to the Forfeiture set forth in the preceding paragraph.

4. Each of Sponsor and the Individual Class B Holders hereby confirms that (i) it consents to Buyer’s entering into the Business Combination Agreement, and (ii) from the date of the Business Combination Agreement until the earlier of the Closing or the termination of the Business Combination Agreement in accordance with its terms, Sponsor or such Individual Class B Holder agrees to not redeem any Cayman Class A Shares (or, if applicable, shares of Altimar Class A Common Stock) held by it. Buyer agrees that it shall not waive Sponsor’s or any Individual Class B Holder’s obligations under this Section 4 without the consent of all other parties hereto (including each addressee hereof). At the Closing, subject to the terms and conditions of the Business Combination Agreement, Sponsor shall provide funds to Buyer to satisfy the funding of such Altimar Transaction Expenses, after utilizing the unused portion of the working capital amount funded by Sponsor to Buyer prior to the date hereof, that are in excess of the aggregate $27,000,000 cap referenced in, Section 4.03(b) of the Business Combination Agreement. All obligations of Buyer to Sponsor for borrowed money or any payments made to or on behalf of Buyer shall be settled in cash and not through the issuance of warrants or other Equity Securities.

AGREEMENT

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, the Securityholder hereby covenants and agrees as follows:

1. Agreement to Vote. Subject to the earlier termination of this Agreement in accordance with Section 3, the Securityholder, in its capacity as an equityholder of the Company, irrevocably and unconditionally acknowledges

N-1

and agrees that it has validly executed and delivered, and has caused any other holder of record of any of any of the Securityholder’s Covered Units to validly execute and deliver, in each case to the Company, on the date first written above and automatically effective as of the first Business Day following the date that the Proxy Statement/Consent Solicitation Statement/Prospectus included in the Form S-4 is disseminated by Altimar to its shareholders (following the date that the Form S-4 becomes effective), the written consent attached hereto as Exhibit A in respect of all of the Securityholder’s Covered Units. In addition, prior to the Termination Date (as defined herein), the Securityholder, in its capacity as an equityholder of the Company, irrevocably and unconditionally agrees that, at any meeting of the equityholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting, however called and including any adjournment or postponement thereof) and in connection with any written consent of the equityholders of the Company, the Securityholder shall, and shall cause any other holder of record of any of the Securityholder’s Covered Units to:

(a) if and when such meeting is held, appear at such meeting or otherwise cause the Securityholder’s Covered Units to be counted as present thereat for the purpose of establishing a quorum;

(b) vote (or execute and return an action by written consent), or cause to be voted at such meeting (or validly execute and return and cause such consent to be granted with respect to), all of the Securityholder’s Covered Units owned as of the record date for such meeting (or the date that any written consent is executed by the Securityholder) in favor of the Mergers and the adoption of the Business Combination Agreement and any other matters necessary or reasonably requested by the Company for consummation of the Mergers and the other transactions contemplated by the Business Combination Agreement; and

(c) vote (or execute and return an action by written consent), or cause to be voted at such meeting, or validly execute and return and cause such consent to be granted with respect to, all of the Securityholder’s Covered Units against any equityholder proposal and any other action that (i) would reasonably be expected to materially impede, interfere with, delay, postpone or adversely affect the Mergers or any of the other transactions contemplated by the Business Combination Agreement or result in a breach of any covenant, representation or warranty or other obligation or agreement of the Company under the Business Combination Agreement that or (ii) would result in the failure of any condition set forth in Section 11.01 or Section 11.02 of the Business Combination Agreement to be satisfied or result in a breach of any covenant, representation or warranty or other obligation or agreement of the Securityholder contained in this Agreement.

The obligations of the Securityholder specified in this Section 1 shall apply whether or not the Mergers or any action described above are recommended by the Board of Managers of the Company. For purposes of this Agreement, “Person” shall mean individual, corporation, partnership, limited partnership, limited liability company, syndicate, person (including, without limitation, a “person” as defined in Section 13(d)(3) of the Exchange Act), trust, association or entity or government, political subdivision, agency or instrumentality of a government.

2. No Inconsistent Agreements. The Securityholder hereby covenants and agrees that the Securityholder shall not, at any time prior to the Termination Date, (i) enter into any voting agreement or voting trust with respect to any of the Securityholder’s Covered Units that is inconsistent in any respect with the Securityholder’s obligations pursuant to this Agreement, (ii) grant a proxy or power of attorney with respect to any of the Securityholder’s Covered Units that is inconsistent with the Securityholder’s obligations pursuant to this Agreement, or (iii) enter into any agreement or undertaking that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying, its obligations pursuant to this Agreement.

3. Termination. This Agreement shall automatically terminate, without any notice or other action by any party, be void ab initio and no party shall have any further obligations or liabilities under this Agreement, upon the earliest of (i) the termination of the Business Combination Agreement in accordance with its terms, (ii) the time this Agreement is terminated upon the mutual written agreement of the Company, Altimar, Merger Sub and the Securityholder, or (iii) the election of the Securityholder in its sole discretion to terminate this Agreement following any material modification or amendment to, or the waiver of any provision of, the Business

N-2

Combination Agreement, as in effect on the date hereof, that reduces the aggregate Fathom Consideration or changes the form of consideration payable to the Securityholder in the Mergers, (in each case, without the Securityholder’s prior written consent) (the earliest such date under clause (i), (ii) and (iii) being referred to herein as the “Termination Date”); provided, that the provisions set forth in Sections 9 to 22 shall survive the termination of this Agreement; provided, further, that termination of this Agreement shall not relieve any party hereto from any liability for any Willful Breach of this Agreement prior to such termination.

4. Representations and Warranties of the Securityholder. The Securityholder hereby represents and warrants to Altimar as to itself as follows:

(a) The Securityholder is the only record and a beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good, valid and marketable title to, the Owned Units, free and clear of Liens other than as created by this Agreement and Permitted Liens. As of the date hereof, other than the Owned Units and any other equity securities of the Company that become Covered Units that the Securityholder acquires record or beneficial ownership after the date hereof that is either permitted pursuant to, or acquired in accordance with, the Business Combination Agreement, the Securityholder does not own beneficially or of record any equity securities of the Company (or any securities convertible into equity securities of the Company).

(b) The Securityholder (i) except as provided in this Agreement, has full voting power, full power of disposition and full power to issue instructions with respect to the matters set forth herein, in each case, with respect to the Securityholder’s Covered Units, (ii) has not entered into any voting agreement or voting trust with respect to any of the Securityholder’s Covered Units that is inconsistent with the Securityholder’s obligations pursuant to this Agreement other than the Fathom LLCA, (iii) has not granted a proxy or power of attorney with respect to any of the Securityholder’s Covered Units that is inconsistent with the Securityholder’s obligations pursuant to this Agreement and (iv) has not entered into any agreement or undertaking that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying, its obligations pursuant to this Agreement.

(c) The Securityholder is duly organized, validly existing and, to the extent such concept is applicable, in good standing under the Laws of the jurisdiction of its organization and has all requisite corporate or other power and authority and has taken all corporate or other action necessary in order to, execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereby. This Agreement has been duly executed and delivered by the Securityholder and constitutes a valid and binding agreement of the Securityholder enforceable against the Securityholder in accordance with its terms, subject to the Enforceability Exceptions.

(d) Other than the filings, notices and reports pursuant to, in compliance with or required to be made under the Exchange Act, no filings, notices, reports, consents, registrations, approvals, permits, waivers, expirations of waiting periods or authorizations are required to be obtained by the Securityholder from, or to be given by the Securityholder to, or be made by the Securityholder with, any Governmental Authority in connection with the execution, delivery and performance by the Securityholder of this Agreement, the consummation of the transactions contemplated hereby (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement).

(e) The execution, delivery and performance of this Agreement by the Securityholder do not, and the consummation of the transactions contemplated hereby (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement) will not, constitute or result in (i) if the Securityholder is a legal entity, a breach or violation of, or a default under, the limited liability company agreement or similar governing documents of the Securityholder, (ii) with or without notice, lapse of time or both, a breach or violation of, a termination (or right of termination) of or a default under, the loss of any benefit under, the creation, modification or acceleration of any obligations

N-3

under or the creation of a Lien on the Covered Units (other than Permitted Liens) pursuant to any contract binding upon the Securityholder or, assuming (solely with respect to performance of this Agreement and the transactions contemplated hereby), compliance with the matters referred to in Section 4(d), under any applicable Law to which the Securityholder is subject or (iii) any change in the rights or obligations of any party under any contract legally binding upon the Securityholder, except, in the case of clause (ii) or (iii) directly above, for any such breach, violation, termination, default, creation, loss, acceleration, Lien or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay or impair the Securityholder’s ability to perform its obligations hereunder or to consummate the transactions contemplated hereby (including, for the avoidance of doubt, those covenants, agreements and obligations under this Agreement that relate to the provisions of the Business Combination Agreement).

(f) As of the date of this Agreement, there is no action, proceeding or, to the Securityholder’s knowledge, investigation pending against the Securityholder or, to the knowledge of the Securityholder, threatened against the Securityholder that questions the beneficial or record ownership of the Securityholder’s Owned Units, the validity of this Agreement or the performance by the Securityholder of its obligations under this Agreement.

(g) The Securityholder understands and acknowledges that the Altimar and Merger Sub entered into the Business Combination Agreement in reliance upon Securityholder’s execution and delivery of this Agreement and the representations, warranties, covenants and other agreements of the Securityholder contained herein.

5. Certain Covenants of the Securityholder. Except in accordance with the terms of this Agreement, the Securityholder hereby covenants and agrees as follows:

(a) The Securityholder hereby agrees not to, directly or indirectly, prior to the Termination Date, except in connection with the consummation of the Mergers, (i) sell, transfer, pledge, encumber, assign, hedge, swap, convert or otherwise dispose of (including by merger (including by conversion into securities or other consideration), by tendering into any tender or exchange offer, by operation of Law or otherwise), either voluntarily or involuntarily (collectively, “Transfer”), or enter into any contract or option with respect to the Transfer of any of the Securityholder’s Covered Units, (ii) amend, modify, supplement, withdraw, revoke or otherwise rescind the written consent attached hereto as Exhibit A in respect of all of the Securityholder’s Covered Units, or (iii) take any action that would make any representation or warranty of the Securityholder contained herein untrue or incorrect or have the effect of preventing or materially delaying the Securityholder from or in performing its obligations under this Agreement; provided, however, that nothing herein shall prohibit a Transfer (A) to an Affiliate of the Securityholder, (B) occurring by will, testamentary document or intestate succession upon the death of a Securityholder who is an individual or (C) pursuant to community property laws or divorce decree (each, a “Permitted Transfer”); provided, further, that any Permitted Transfer shall be permitted only if, as a precondition to such Transfer, the transferee also agrees in a writing, reasonably satisfactory in form and substance to the Company, to assume all of the obligations of the Securityholder under, and be bound by all of the terms of, this Agreement in respect of the Covered Units so Transferred and any Covered Units subsequently acquired; provided, further, that any Transfer permitted under this Section 5(a) shall not relieve the Securityholder of its obligations under this Agreement. Any Transfer in violation of this Section 5(a) with respect to the Securityholder’s Covered Units shall be null and void. Nothing in this Agreement shall prohibit direct or indirect transfers of equity or other interests in a Securityholder.

(b) The Securityholder hereby authorizes the Company to maintain a copy of this Agreement at either the executive office or the registered office of the Company.

6. Further Assurances. From time to time, at Altimar’ request and without further consideration, the Securityholder shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or reasonably requested to effect the actions and consummate the transactions contemplated by this Agreement.

N-4

The Securityholder hereby authorizes the Company and Altimar to publish and disclose in any announcement or disclosure to the extent required by law, rule or regulation by the SEC the Securityholder’s identity and ownership of the Covered Units and the nature of the Securityholder’s obligations under this Agreement; provided, that prior to any such publication or disclosure the Company and Altimar have provided the Securityholder with a reasonable opportunity to review and comment upon such announcement or disclosure, which comments the Company and Altimar will consider in good faith.

8. Changes in Capital Securities. In the event of a split, dividend or distribution, or any change in the Company’s capital securities by reason of any split-up, reverse split, recapitalization, combination, reclassification, exchange of units or the like, the terms “Owned Units” and “Covered Units” shall be deemed to refer to and include such securities as well as all such security dividends and distributions and any securities into which or for which any or all of such units may be changed or exchanged or which are received in such transaction.

14. No Third-Party Beneficiaries. The Securityholder hereby agrees that its representations, warranties and covenants set forth herein are solely for the benefit of Altimar and Merger Sub in accordance with and subject to the terms of this Agreement, and this Agreement is not intended to, and does not, confer upon any Person other than the parties hereto any rights or remedies hereunder, including the right to rely upon the representations and warranties set forth herein, and the parties hereto hereby further agree that this Agreement may only be enforced against, and any Action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement may only be made against, the Persons expressly named as parties hereto; provided, that the Company shall be an express third party beneficiary with respect to Section 4, Section 5(a), Section 5(b) and Section 7 hereof.

15. Governing Law and Venue; Service of Process; Waiver of Jury Trial.

(a) This Agreement, and all claims or causes of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby, shall be governed by, and construed in accordance with, the Laws of the State of Delaware, without giving effect to any choice or conflict of law provision or rule.

(b) Each party to this Agreement (a) irrevocably and unconditionally submits to the personal jurisdiction of the federal courts of the United States of America located in the State of Delaware and the Court of Chancery of the State of Delaware, (b) agrees that it will not attempt to deny or defeat such personal jurisdiction by motion or other request for leave from any such court, (c) agrees that any actions or proceedings arising in connection with this Agreement or the Business Combination Agreement or the transactions contemplated hereby or by the Business Combination Agreement shall be brought, tried and determined only in the Delaware Court of Chancery (or, only if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware), (d) waives any claim of improper venue or any claim that those courts are an inconvenient forum and (e) agrees that it will not bring any action relating to this Agreement or the Business Combination Agreement or the transactions contemplated hereunder or thereunder in any court other than the aforesaid courts. The parties to this Agreement agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in Section 11 or

N-6

in such other manner as may be permitted by applicable Law, shall be valid and sufficient service thereof. EACH OF THE PARTIES HERETO HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATED TO THE BUSINESS COMBINATION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

16. Assignment; Successors. No party hereto shall assign this Agreement or any part hereof without the prior written consent of the other parties hereto. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Any attempted assignment in violation of the terms of this Section 16 shall be null and void, ab initio.

17. Enforcement. The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. The parties acknowledge and agree that (a) the parties shall be entitled to an injunction, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, including the Securityholder’s obligations to vote its Covered Units as provided in this Agreement or the written consent attached hereto as Exhibit A, without proof of damages, this being in addition to any other remedy to which they are entitled under this Agreement, and (b) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, none of the parties would have entered into this Agreement. Each party agrees that it will not oppose the granting of specific performance and other equitable relief on the basis that the other parties have an adequate remedy at Law or that an award of specific performance is not an appropriate remedy for any reason at Law or equity. The parties acknowledge and agree that any party seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this Section 17 shall not be required to provide any bond or other security in connection with any such injunction.

18. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, the other provisions of this Agreement shall remain in full force and effect. The parties further agree that if any provision contained herein is, to any extent, held invalid or unenforceable in any respect under the Laws governing this Agreement, they shall take any actions necessary to render the remaining provisions of this Agreement valid and enforceable to the fullest extent permitted by Law and, to the extent necessary, shall amend or otherwise modify this Agreement to replace any provision contained herein that is held invalid or unenforceable with a valid and enforceable provision giving effect to the intent of the parties.

19. Counterparts. This Agreement may be executed in two (2) or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. This Agreement shall become effective when each party shall have received a counterpart hereof signed by all of the other parties. Signatures delivered electronically or by facsimile shall be deemed to be original signatures.

20. Interpretation and Construction. Unless the express context otherwise requires:

(a) the words “hereof,” “herein” and “hereunder” and words of similar import, when used in this Agreement, shall refer to this Agreement as a whole and not to any particular provision of this Agreement;

PART II: INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

The Cayman Islands Companies Act does not limit the extent to which a company’s memorandum and articles of association may provide for indemnification of officers and directors. However, such provision may be held by the Cayman Islands courts to be unenforceable, to the extent it seeks to indemnify or exculpate a fiduciary in respect of their actual fraud or willful default, or for the consequences of committing a crime. Altimar II’s Existing Organizational Documents provide for indemnification of its officers and directors to the maximum extent permitted by law, including for any liability incurred in their capacities as such, except through their own actual fraud, willful default or willful neglect. Altimar II has also entered into agreements with its directors and officers to provide contractual indemnification in addition to the indemnification provided for in our amended and restated memorandum and articles of association. Altimar II has also purchased a policy of directors’ and officers’ liability insurance that insures its officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures Altimar II against its obligations to indemnify its officers and directors.

Such limitation of liability and indemnification does not affect the availability of equitable remedies. In addition, Altimar II has been advised that, in the opinion of the Securities and Exchange Commission, indemnification for liabilities arising under the Securities Act of 1933, as amended (the “Securities Act”), is against public policy as expressed in the Securities Act and is therefore unenforceable.

Fathom is governed by the Delaware General Corporation Law, as the same exists or may hereafter be amended (the “DGCL”). Section 145 of the DGCL (“Section 145”) provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation) by reason of the fact that such person is or was a director, officer, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnification may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful. Section 145 also provides that a Delaware corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of such corporation, under the same conditions, except that such indemnification is limited to expenses (including attorneys’ fees) actually and reasonably incurred by such person, and except that no indemnification is permitted without judicial approval if such person is adjudged to be liable to such corporation. Where an officer or director of a corporation is successful, on the merits or otherwise, in the defense of any action, suit or proceeding referred to above, or any claim, issue or matter therein, the corporation must indemnify that person against the expenses (including attorneys’ fees) which such officer or director actually and reasonably incurred in connection therewith.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would otherwise have the power to indemnify such person against such liability under Section 145.

The Registrant’s Proposed Charter and Proposed Bylaws provide that Fathom will indemnify to the fullest extent permitted by law any person made or threatened to be made a party to an action or proceeding, whether

II-1

criminal, civil, administrative or investigative, by reason of the fact that he, his testator or intestate is or was a director, officer or employee of Fathom or any predecessor of Fathom, or serves or served at any other corporation, partnership, joint venture, trust or other enterprise as a director, officer, employee or agent at the request of Fathom or any predecessor of Fathom.

The Registrant’s Proposed Bylaws provide for mandatory indemnification to the fullest extent permitted by DGCL against all expenses (including attorney’s fees), judgments, fines, ERISA excise taxes or penalties and amounts paid in settlements.

The Registrant’s Proposed Charter eliminates the liability of a director of Fathom to the fullest extent under applicable law. Pursuant to Section 102(b)(7) of the DGCL, a corporation may eliminate the personal liability of a director to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except for liabilities arising (i) from any breach of the director’s duty of loyalty to the corporation or its stockholders, (ii) from acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) from any transaction from which the director derived an improper personal benefit.

These provisions may be held not to be enforceable for certain violations of the federal securities laws of the United States.

The Registrant’s directors and executive officers are covered by insurance maintained by Fathom against specified liabilities for actions taken in their capacities as such, including liabilities under the Securities Act. In addition, Fathom has entered into contracts with its directors and executive officers providing indemnification of such directors and executive officers by Fathom to the fullest extent permitted by law, subject to certain limited exceptions.

Item 22. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement: (i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement (notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement); and (iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(6) That, prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the registrant undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

II-5

(7) That every prospectus (i) that is filed pursuant to the immediately preceding paragraph, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment has become effective, and that for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(8) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(9) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of, and included in, this registration statement when it became effective.

(10) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers, and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission, such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer, or controlling person of the registrant in the successful defense of any action, suit, or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
