Item 1.01. Entry into a Material Definitive Agreement.

Amendment of Business Combination Agreement

As previously disclosed in the Current Report on Form 8-K (the “Signing 8-K”) filed on July 19, 2021 by Altimar Acquisition Corp. II, a Cayman Islands exempted company (“Altimar”), Altimar entered into a definitive business combination agreement (as it may be amended, restated, amended and restated or otherwise supplemented from time to time, the “Business Combination Agreement”), dated as of July 15, 2021, by and among Altimar, Fathom Holdco, LLC, a Delaware limited liability company (“Fathom”), Rapid Merger Sub, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of Altimar (“Rapid Merger Sub”), and the other parties thereto, a copy of which is attached to the Signing 8-K as Exhibit 2.1 and incorporated herein by reference. Capitalized terms used but not otherwise defined in this Current Report have the meanings given to such terms in the Business Combination Agreement.

On November 16, 2021, Altimar, Fathom, Rapid Merger Sub and the other parties thereto entered into an amendment of the Business Combination Agreement (the “BCA Amendment”) to amend the agreement as follows:

(a) to reduce the minimum Available Cash Amount required on the Closing Date to $90 million (the “Amended Minimum Available Cash Amount”);

(b) to reflect a subscription commitment by the Backstop Investors (as defined below) to purchase up to an aggregate of $10 million of Altimar Class A Common Stock at a purchase price of $10 per share (the “Backstop Shares”), solely to the extent necessary to satisfy the Amended Minimum Available Cash Amount (the “CORE Backstop Subscription”);

(c) to amend the definition of Balance Sheet Contribution Amount to reflect the mutual agreement of the parties (as permitted by such definition) to reduce the required Balance Sheet Contribution Amount to $10 million or such lesser amount mutually agreed in writing by Fathom and Altimar;

(d) to amend the definition of Debt Pay-Down Amount to reflect the mutual agreement of the parties (as permitted by such definition) to reduce the required Debt Pay-Down Amount to $20 million or such lesser amount mutually agreed upon by Fathom and Altimar;

(e) to eliminate certain of the existing mechanics and definitions (including the definitions Altimar Stockholder Redemption Ratio and Redemption Forfeiture Ratio) relating to the potential forfeiture at the Closing of Altimar Class C Common Stock held by the Founders on a formulaic basis relating to the number of Altimar Class A Ordinary Shares redeemed in connection with the Altimar Stockholder Redemption, and to provide instead that 2,587,500 shares of Altimar Class A Common Stock held by the Founders shall be automatically forfeited at the Closing;

(f) to amend the definition of Closing Seller Equity Consideration to increase the aggregate number of shares of Altimar Class A Common Stock and New Fathom Class A Units by 1,293,750;

(g) to attach a new form of Investor Rights Agreement, substantially in the form attached hereto as Exhibit B to the BCA Amendment, which has been modified to clarify that any Fathom shares acquired by the Backstop Investors pursuant to the CORE PIPE Subscription (after giving effect to conversion of the Altimar Class A Common Stock in the Fathom Merger) are not Covered Shares (as defined in the form of Investor Rights Agreement);

(h) to attach a new form of Registration Rights Agreement, substantially in the form attached hereto as Exhibit C to the BCA Amendment, which, among other things, clarifies that the Backstop Shares shall be excluded from the definition of “Registrable Security” for purposes of the Registration Rights Agreement;

1

(i) to attach a new form of Tax Receivable Agreement, substantially in the form attached hereto as Exhibit D to the BCA Amendment, which has been modified to clarify certain definitions and provisions set forth in the form of the agreement initially attached to the Business Combination Agreement; and

(j) to make related, conforming changes to other definitions and provisions of the Business Combination Agreement to reflect the amendments described above.

The foregoing description of the BCA Amendment is not complete and is subject to and qualified in its entirety by reference to the BCA Amendment, a copy of which is attached to this Current Report as Exhibit 2.1, and the terms of which are incorporated by reference herein.

CORE Backstop Subscription

On November 16, 2021, Altimar and Fathom entered into an agreement with CORE Industrial Partners Fund I, L.P. and CORE Industrial Partners Fund I Parallel, L.P. (together with their permitted transferees and assigns, 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, resulting in aggregate proceeds of up to $10.0 million (the “CORE Backstop Agreement”) only if (i) the Amended Minimum Available Cash Amount is not satisfied and (ii) the positive difference, if applicable, between the Amended Minimum Available Cash Amount and the Available Cash Amount does not exceed $10.0 million, and subject to the other terms and conditions of the CORE Backstop Agreement.

The CORE Backstop Agreement contains customary representations, warranties, covenants and agreements of Altimar, Fathom and the Backstop Investors and is 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 Backstop Investors) and termination rights (including a termination right if the transactions contemplated by the Business Combination Agreement have not been consummated by December 31, 2021, other than as a result of breach by the terminating party). If the conditions to the consummation of the CORE Backstop Subscription are triggered, the CORE Backstop Subscription is expected to close immediately prior to the Closing, subject to the terms and conditions of the CORE Backstop Agreement.

The foregoing description of the CORE Backstop Agreement is not complete and is subject to and qualified in its entirety by reference to the CORE Backstop Agreement, a copy of which is attached to this Current Report as Exhibit 10.1, and the terms of which are incorporated by reference herein

In addition and as also disclosed in the Signing 8-K, the Founders, Altimar, Fathom and the other parties thereto entered into the Forfeiture and Support Agreement, dated as of July 15, 2021 (the “Forfeiture and Support Agreement”).

On November 16, 2021, the Founders, Altimar, Fathom and the other parties thereto entered into an amendment of the Forfeiture and Support Agreement (the “FSA Amendment” and together with the “Forfeiture and Support Agreement,” the “Amended Forfeiture and Support Agreement”) to amend the agreement as follows:

(a) to reduce the strike price for Altimar Sponsor II, LLC’s earnout from $15.00 per share to $12.50 per share;

(b) to remove the current definition of “Forfeited Shares” and replace it in its entirety with: 2,587,500 aggregate shares of Altimar Class A Common Stock with such forfeiture allocated among the Founders as set forth in Schedule B of the Amended Forfeiture and Support Agreement (the “Revised Forfeited Shares”);

(c) to provide for the forfeiture by the Founders of the Revised Forfeited Shares;

2

(d) to reflect the issuance of 1,293,750 additional newly issued shares of Altimar Class A Common Stock to direct and indirect equityholders of Fathom, which shall be allocated in accordance with the terms and conditions of the Business Combination Agreement, as amended by the BCA Amendment, and the Allocation Schedule; and

(e) to make related, conforming changes to other definitions and provisions of the Forfeiture and Support Agreement to reflect the amendments described above.

The foregoing description of the FSA Amendment is not complete and is subject to and qualified in its entirety by reference to the FSA Amendment, a copy of which is attached to this Current Report as Exhibit 10.2, and the terms of which are incorporated by reference herein.

Additional Information

Important Information About the Business Combination and Where to Find It

In connection with the proposed Business Combination, Altimar has filed with the SEC a registration statement on Form S-4 (the “Registration Statement”) which includes a preliminary proxy statement/prospectus, and certain other related documents, which are both the proxy statement to be distributed to holders of Altimar’s ordinary shares in connection with Altimar’s solicitation of proxies for the vote by Altimar’s shareholders with respect to the Business Combination and other matters as may be described in the Registration Statement, as well as the prospectus relating to the offer and sale of the securities of Fathom to be issued in the Business Combination. Altimar’s shareholders and other interested persons are advised to read the preliminary proxy statement/prospectus included in the Registration Statement and the amendments thereto and, when available, the definitive proxy statement/prospectus, as these materials will contain important information about the parties to the Business Combination Agreement, Altimar and the Business Combination. After the Registration Statement is declared effective, the definitive proxy statement/prospectus will be mailed to shareholders of Altimar as of a record date to be established for voting on the Business Combination and other matters as may be described in the Registration Statement. Shareholders will also be able to obtain copies of the proxy statement/prospectus and other documents filed with the SEC that will be incorporated by reference in the proxy statement/prospectus, without charge, once available, at the SEC’s website at www.sec.gov, or by directing a request to: Altimar Acquisition Corp. II, 40 West 57th Street, 33rd Floor, New York, New York 10019, or by calling (212) 287-6767.

Participants in the Solicitation

Altimar and its directors and executive officers may be deemed participants in the solicitation of proxies from Altimar’s shareholders with respect to the Business Combination. A list of the names of those directors and executive officers and a description of their interests in Altimar is contained in Altimar’s final prospectus from its initial public offering, which was filed with the SEC on February 5, 2021 and in the Registration Statement, and is available free of charge at the SEC’s website at www.sec.gov, or by directing a request to Altimar Acquisition Corp. II, 40 West 57th Street, 33rd Floor, New York, New York 10019, or by calling (212) 287-6767.

Fathom and its respective managers and executive officers may also be deemed to be participants in the solicitation of proxies from Altimar’s shareholders in connection with the Business Combination. A list of the names of such directors and executive officers and information regarding their interests in the Business Combination are contained in the Registration Statement.

Forward-Looking Statements

This Current Report on Form 8-K includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. Altimar’s and Fathom’s actual results may differ from their expectations, estimates and projections and consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” “target,” “goal,” and similar expressions are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, Altimar’s and Fathom’s expectations with respect to future

3

performance and anticipated financial impacts of the Business Combination, the satisfaction of the closing conditions to the Business Combination and the timing of the completion of the Business Combination. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside Altimar’s and Fathom’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) the outcome of any legal proceedings that may be instituted against Altimar and/or Fathom following the announcement of the Business Combination Agreement and the transactions contemplated therein; (2) the inability of Altimar to complete the contemplated transactions with Fathom; (3) the occurrence of any event, change or other circumstance that could give rise to the termination of the Business Combination Agreement or could otherwise cause the transactions contemplated therein to fail to close; (4) the ability to meet the NYSE’s listing standards following the consummation of the transactions contemplated by the proposed Business Combination; (5) the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination; (6) the ability to recognize the anticipated benefits of the Business Combination, which may be affected by, among other things, the amount of funds available in Altimar’s trust account following any redemptions by Altimar’s shareholders; (7) costs related to the Business Combination; (8) the possibility that Fathom or the combined company may be adversely affected by other economic, business, and/or competitive factors; and (9) other risks and uncertainties indicated from time to time in the proxy statement/prospectus relating to the Business Combination, including those under “Risk Factors” in the Registration Statement, and in Altimar’s other filings with the SEC, including those factors discussed in the registration statement and final prospectus relating to Altimar’s initial public offering filed with the SEC on February 5, 2021 and Item 1A. Risk Factors of the Form 10-Q for the quarters ended March 31, 2021 filed with the SEC on June 1, 2021, June 30 2021 filed with the SEC on August 12, 2021 and September 30, 2021 filed with the SEC on November 10, 2021. Altimar cautions that the foregoing list of factors is not exclusive. Altimar cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. Altimar does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions or circumstances on which any such statement is based.

No Offer or Solicitation

This Current Report on Form 8-K shall not constitute a solicitation of a proxy, consent or authorization with respect to any securities or in respect of the Business Combination. This Current Report on Form 8-K shall also not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any states or jurisdictions in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of section 10 of the Securities Act.

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.

5

(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.

ARTICLE II.

CORPORATE GOVERNANCE MATTERS

2.1 Initial Board Composition; Classified Board. Effective as of the Closing Date, the Board shall satisfy all applicable rules and regulations of the Securities and Exchange Commission and the Exchange and is anticipated to be comprised of eleven (11) Directors, as follows: (i) ten (10) Directors designated by the CORE Designator (who shall be the initial CORE Nominees), and (ii) one (1) Director, to be jointly designated as mutually agreed by the CORE Designator and Altimar Sponsor II, LLC, who shall be independent as required by the Securities and Exchange Commission and applicable listing exchange rules and regulations. The initial chairman of the Board (the “Chairman”) is anticipated to be TJ Chung. Mr. Chung shall be appointed as the Chairman for so long as he is a member of the Board, and, thereafter, the Chairman shall be elected by a majority of the Board. The parties hereto acknowledge and agree that, consistent with the Company Charter, the Board shall be divided into three classes designated as Class I, Class II and Class III and that the Directors initially shall be allocated among such classes as set forth on Schedule B hereto.

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.

6

(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 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.

7

(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 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.

8

(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 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

9

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

7

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

8

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 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

10

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 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

11

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).

12

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.

15

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.

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.

16

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.

17

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 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

18

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 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

19

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.

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).

(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).

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

16

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.

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.

17

(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 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.

18

(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 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.”

19

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.

20

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.

21

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

22

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 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

23

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.

Section 7.5.    Severability.

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.

Section 7.6.    Assignments; Amendments; Successors; No Waiver.

25

(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.

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.

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

26

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 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

27

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 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.

28

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.

WHEREAS, in connection with the Transactions, Subscriber desires to subscribe for and purchase from the Company, following the Domestication but immediately prior to the consummation of the Transactions, that number of the Company’s Class A Common Stock, par value $0.0001 per share (the “Class A Common Shares”), determined in accordance with the Backstop Condition Formula (as defined below) (such number of shares determined in accordance with the Backstop Condition Formula and as specified in the Closing Notice, the “Subscribed Shares”) for a purchase price of $10.00 per share (the “Per Share Price” and the aggregate of such Per Share Price for all Subscribed Shares being referred to herein as the “Purchase Price”), if and only if the sum of: (i) the expected balance in the Company’s Trust Account after giving effect to the Altimar Stockholder Redemption following the deadline to validly submit redemption requests (it being understood that this clause (i) shall not take into account any potential or actual reversals of redemption requests and it being further understood that the Trust Account balance after giving effect to the Altimar Stockholder Redemption in this clause (i) shall be certified or otherwise documented by the Company’s transfer agent as promptly as practicable following the redemption deadline) and (ii) the gross proceeds from the Original PIPE Investment actually received by the Company (or its validly designated escrow agent) or reasonably expected by the Company to be received by the Company (or its validly designated escrow agent) prior to the Closing Date (the sum of foregoing clauses (i) and (ii), the “Available Closing Date Cash”)), is less than $90,000,000 (such $90,000,000 amount, the “Minimum Cash Condition” and such condition to Subscriber’s purchase, the “Backstop Condition”);

1

WHEREAS, the number of Subscribed Shares to be purchased by Subscriber shall equal: (i) the positive difference of the Minimum Cash Condition minus the Available Closing Date Cash (such amount, if applicable, the “Shortfall Amount”) divided by (ii) 10, provided, that (A) Subscriber’s obligation to purchase Subscribed Shares shall be conditioned upon the Shortfall Amount being no greater than $10,000,000 and provided, further that (B) Subscriber shall in no event be obligated to purchase more than 1,000,000 Subscribed Shares for an aggregate Subscription amount of $10,000,000 (the “Backstop Condition Formula”); and

WHEREAS, if and only if the Backstop Condition is triggered (such determination to be made by the Company in its sole and absolute discretion, subject to Subscriber’s confirmation, such confirmation which shall not be unreasonably withheld by Subscriber), the Company desires to issue and sell to Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price by or on behalf of Subscriber to the Company (or its validly designated escrow agent).

NOW, THEREFORE, in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions (including the Backstop Condition), 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”). For avoidance of doubt, the respective obligations of CORE Fund I and CORE Fund I Parallel to purchase Subscribed Shares hereunder is expressly limited to the number of the Subscribed Shares listed by such fund’s respective name on Subscriber’s signature page hereto (and in no event will either of CORE Fund I or CORE Fund I Parallel be obligated to purchase a greater number of the Subscribed Shares than so listed by such fund’s name on Subscriber’s signature page hereto). Subscriber understands that, pursuant to the Domestication, the Subscribed Shares that will be issued pursuant hereto shall be shares of common stock in a Delaware corporation. Upon Subscriber’s request, the Company shall deliver to Subscriber: (i) a duly completed and executed Internal Revenue Service Form W-9 or W-8BenE, as applicable and (ii) the names, email addresses and telephone numbers of two company contacts (the “Wire Verification Information”). The Company shall deliver the Wire Verification Information as soon as practicable upon receiving such request from the Subscriber.

Section 2. Closing.

(a) The consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the closing date of the Transactions contemplated by the Transaction Agreement (the “Closing Date”), immediately prior to or substantially concurrently with the consummation of the Transactions to be completed on the Closing Date. The Company and Subscriber hereby agree that, if the Backstop Condition is triggered, the Purchase Price proceeds shall be applied towards satisfying the Minimum Cash Condition.

(b) At least two (2) Business Days before the anticipated Closing Date, the Company shall deliver written notice to Subscriber (the “Closing Notice”) which shall: (i) indicate that the Backstop Condition has been triggered, (ii) specify the anticipated Closing Date, (iii) specify (x) the number of Subscribed Shares to be purchased by Subscriber in accordance with the Backstop Condition Formula and (y) the Purchase Price, (iv) provide the wire instructions for delivery of the Purchase Price to the Company and (v) confirm the Wire Verification Information, if previously provided to Subscriber upon request by Subscriber. No later than 5:00 PM New York

City time on one (1) Business Day prior to the Closing Date, Subscriber shall deliver the Purchase Price for the Subscribed Shares by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice, such funds to be held by the Company in escrow until the Closing, and deliver to the Company such information as is reasonably requested in the Closing Notice in order for the Company to issue the Subscribed Shares to Subscriber, including, without limitation, the legal name(s) of the person(s) in whose name the Subscribed Shares are to be issued and a duly completed and executed Internal Revenue Service Form W-9 or appropriate Form W-8. Upon satisfaction (or, if applicable, waiver) of the conditions set forth in this Section 2, the Company shall deliver to Subscriber (i) at the Closing, the Subscribed Shares in book entry form, free and clear of any liens or other restrictions (other than those arising under this Backstop Subscription Agreement or applicable securities laws), in the name of Subscriber (or its nominee in accordance with its delivery instructions), and (ii) as promptly as practicable after the Closing, evidence from the Company’s transfer agent of the issuance to Subscriber of the Subscribed Shares on and as of the Closing Date. In the event that (i) the Company does not accept the Subscription or (ii) the consummation of the Transactions does not occur within three (3) Business Days after the anticipated Closing Date specified in the Closing Notice, unless otherwise agreed to in writing by the Company and Subscriber, the Company shall promptly (but in no event later than two (2) Business Days after the anticipated Closing Date specified in the Closing Notice) return the funds so delivered by Subscriber to the Company by wire transfer in immediately available funds to the account specified by Subscriber, and any book entries shall be deemed cancelled. 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 Backstop 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. For the purposes of this Backstop Subscription Agreement, “Business Day” means any day other than a Saturday, Sunday or any other day on which commercial banks are required or authorized to close in the State of New York.

(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 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

3

(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 Backstop 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 Backstop Subscription Agreement to be performed, satisfied or complied with by it at or prior to the Closing.

For purposes of this Backstop 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.

(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 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 Backstop Subscription Agreement, no registration under the Securities Act is required for the offer and sale of the Subscribed Shares by the Company to Subscriber.

(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.

(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) 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.

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.

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

12

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

13

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.

(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:

14

(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

15

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 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.

16

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.

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

17

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.

(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

18

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.

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 and Fathom will rely on the acknowledgments, understandings, agreements, representations and warranties of Subscriber contained in this Backstop Subscription Agreement. Prior to the Closing, Subscriber agrees to promptly notify the Company and Fathom 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 will rely on the respective acknowledgments, understandings, agreements, representations and warranties made by each of the Company and Fathom contained in this Backstop Subscription Agreement. Prior to the Closing, each of the Company and Fathom agree to promptly notify Subscriber 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 and 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 Backstop 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.

19

(d) Subscriber shall pay all of its own expenses in connection with this Backstop Subscription Agreement and the transactions contemplated herein, except as expressly set forth herein.

(e) Neither this Backstop 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 Backstop 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 Backstop 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 Backstop 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 Backstop 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.

(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 Backstop Subscription Agreement with the Commission as an exhibit to a periodic report of the Company or a registration statement of the Company.

(h) This Backstop Subscription Agreement may not be amended, modified or waived except by an instrument in writing, signed by each of the parties hereto.

(i) This Backstop 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.

20

(j) Except as otherwise provided herein (including the next sentence hereof), this Backstop 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 Backstop 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 Backstop 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 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 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 Backstop 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 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.

(m) If any provision of this Backstop 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.

21

(n) No failure or delay by a party hereto in exercising any right, power or remedy under this Backstop 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 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.

(p) This Backstop 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.

Re: Amendment to Forfeiture and Support Agreement

Ladies and Gentlemen:

Reference is made to that certain Forfeiture and Support Agreement, dated as of July 15, 2021 (as the same may be amended, restated or amended and restated from time to time in accordance with its terms, the “Forfeiture and Support Agreement”), by and among Altimar Acquisition Corp. II, a Cayman Islands exempted company (the “Buyer”), Altimar Sponsor II, LLC, a Delaware limited liability company (the “Sponsor”), the individuals identified on the signature pages thereto (each, an “Individual Class B Holder”), CORE Industrial Partners, LLC, a Delaware Limited Liability Company (“CORE”), Fathom Holdco, LLC, a Delaware limited liability company (“Fathom”), 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”). Unless otherwise expressly provided herein, capitalized terms shall have the respective meanings assigned to them in the Forfeiture and Support Agreement.

RECITALS

WHEREAS, Buyer, Sponsor and the Individual Class B Holders have entered into the Forfeiture and Support Agreement;

WHEREAS, pursuant to Section 13 of the Forfeiture and Support Agreement, such agreement may only be changed, amended or modified by a written instrument executed by all parties thereto (including each addressee thereof); and

WHEREAS, Buyer, Sponsor, the Individual Class B Holders, CORE, Fathom and the Fathom Blockers desire to amend certain provisions of the Forfeiture and Support Agreement as set forth herein.

NOW, THEREFORE, in consideration of the premises and mutual agreements hereinafter set out and of other good and valuable consideration (the receipt and sufficiency of which are hereby acknowledged), the parties hereby agree as follows:

1.    Amendments to the Forfeiture and Support Agreement. Effective as of the date hereof:

a.    Amendment to Section 2. Section 2 of the Forfeiture and Support Agreement is hereby amended and replaced in its entirety with the following:

“Effective upon and subject to the Closing, (a) Sponsor and each Individual Class B Holder shall irrevocably automatically forfeit and surrender, for no additional consideration and without any further action on the part of any other Person, its respective allocable portion of the Forfeited Shares (as defined below), which would otherwise be held by the Sponsor or such Individual Class B Holders as a result of the automatic conversion of shares of Altimar Class C Common Stock after giving effect to the Anti-dilution Waiver (the “Forfeiture”), the Domestication and the Closing and (b) Buyer acknowledges and agrees to, immediately following the Forfeiture, issue 1,293,750 additional newly issued shares of Altimar Class A Common Stock which shall be allocated in accordance with the terms and conditions of the Business Combination Agreement and the Allocation Statement.”

b.    Amendment to Section 11. Clause (a) of Section 11 of the Forfeiture and Support Agreement is hereby amended to replace “$15.00 per share” with “$12.50 per share”.

c.    Amendment to Section 12(d). Section 12(d) of the Forfeiture and Support Agreement is hereby amended and replaced in its entirety with the following:

““Forfeited Shares” means 2,587,500 aggregate shares of Altimar Class A Common Stock allocated among Sponsor and the Individual Class B Holders as set forth in Schedule B. “Forfeited” shall have a correlative meaning to “Forfeiture” for purposes of this Agreement.”

2

d.    Additional Schedules. Schedule A and Schedule B to this Letter Agreement are hereby added, respectively, as Schedule A and Schedule B to the Forfeiture and Support Agreement.

2.    Miscellaneous. The terms, conditions and provisions of the Forfeiture and Support Agreement, as amended by this Letter Agreement, remain in full force and effect. The execution, delivery and effectiveness of this Letter Agreement shall not operate as a waiver of any right, power or remedy of any party under the Forfeiture and Support Agreement, nor constitute a waiver or amendment of any provision of the Forfeiture and Support Agreement. This Letter Agreement shall be governed by, and otherwise construed in accordance with, the terms of the Forfeiture and Support Agreement, as though the other provisions of this Letter Agreement were set forth in the Forfeiture and Support Agreement. This Letter Agreement 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.
