PRELIMINARY PROXY STATEMENT/PROSPECTUS DATED AUGUST 11, 2021, SUBJECT TO COMPLETION

Dear Stockholder:

On May 8, 2021, Star Peak Corp II, a Delaware corporation (“STPC”), entered into an Agreement and Plan of Merger (the “merger agreement”) with STPC II Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of STPC (“Merger Sub”), and Benson Hill, Inc., a Delaware corporation (“Benson Hill”). If the merger agreement is adopted by Benson Hill’s stockholders, the merger agreement and the transactions contemplated thereby, including the issuance of common stock of STPC (“New Benson Hill Common Stock”) to be issued or reserved as the merger consideration, is approved by STPC’s stockholders, and the merger is subsequently completed, Merger Sub will merge with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC (the “merger”).

Immediately prior to the effective time of the merger, each outstanding share of Benson Hill common stock, including common stock held by prior owners of Benson Hill preferred stock (other than shares owned by Benson Hill as treasury stock and dissenting shares) (“Existing Benson Hill Common Stock”), will be cancelled and converted into the right to receive a pro rata portion of approximately 147,562,680 shares of New Benson Hill Common Stock (on a fully-diluted basis but subject to adjustment depending on the final allocation of Earn Out Shares and Earn Out Awards (each, as defined below)), consisting of (i) 130,000,000 shares of New Benson Hill Common Stock, including the portion of such shares of New Benson Hill Common Stock reserved for issuance upon the future exercise of options (less the Exercise Price Options, as defined below) and warrants to purchase capital stock of Benson Hill outstanding immediately prior to the merger and converted into options (“Net New Benson Hill Options”) or warrants (“New Benson Hill Warrants”) to purchase New Benson Hill Common Stock and (ii) 17,562,680 restricted shares of New Benson Hill Common Stock that will be held in escrow until, and vest upon, the achievement of certain earn-out thresholds prior to the third anniversary of the closing of the merger (the “Earn Out Shares”), in each case in accordance with the merger agreement. In addition to the foregoing, incentive equity awards (“Earn Out Awards”) with a value equivalent to 2,037,320 shares of New Benson Hill Common Stock will be granted under the proposed New Incentive Plan (as defined in the merger agreement) to certain holders of Benson Hill Options. The number of Earn Out Shares and Earn Out Awards may be adjusted prior to the closing of the merger on a one-for-one basis pursuant to the terms and subject to the conditions set forth in the merger agreement such that the number of shares of New Benson Hill Common Stock issued as Earn Out Shares or being reserved for or subject to the Earn Out Awards granted shall not exceed 19,600,000 shares of New Benson Hill Common Stock in the aggregate. In addition, a portion of the shares of New Benson Hill Common Stock reserved for issuance under the New Incentive Plan shall be used for Benson Hill options to be assumed under such plan, representing a number of shares of New Benson Hill Common Stock determined at closing and equal to the Aggregate Exercise Price (as defined in the merger agreement) divided by $10.00 (the “Exercise Price Options”, together with the Net New Benson Hill Options, the “New Benson Hill Options”).

Subject to the assumptions set forth under “Basis of Presentation and Glossary” in the accompanying proxy statement/prospectus and assuming that the merger effective date were            , 2021, the record date for the STPC Special Meeting (as defined below), the exchange ratio would have been approximately           of a share of New Benson Hill Common Stock for each share of Existing Benson Hill Common Stock (assuming for purposes of such calculation that all shares of Benson Hill preferred stock and all options and warrants to purchase capital stock of Benson Hill, in each case outstanding immediately prior to the effective time of the merger, have converted into New Benson Hill Common Stock) except, in each case, for any resulting fractional shares of New Benson Hill Common Stock (which will instead be paid in cash in an amount equal to the fractional amount multiplied by $10.00).

The total number of shares of New Benson Hill Common Stock expected to be issued or reserved for issuance pursuant to and at the closing of the merger is approximately 149,600,000 (including the Earn Out Shares and assuming the issuance of all shares of New Benson Hill Common Stock underlying any Net New Benson Hill Options, any New Benson Hill Warrants and any Earn Out Awards, but excluding the Exercise Price Options), and holders of shares of Existing Benson Hill Common Stock as of immediately prior to the closing of the merger (and following the conversion of Benson Hill preferred stock into New Benson Hill Common Stock) will hold, in the aggregate, approximately    % and    % of the issued

and outstanding shares of New Benson Hill Common Stock immediately following the closing of the merger, assuming no shares of STPC common stock are redeemed and the maximum number of shares of STPC common stock are redeemed, respectively.

STPC’s units, Class A Common Stock and public warrants are publicly traded on the New York Stock Exchange (the “NYSE”). We intend to list the combined company’s common stock and public warrants on the NYSE under the symbols BHIL and BHIL WS, respectively, upon the closing of the merger. STPC will not have units traded following closing of the merger.

STPC will hold a special meeting in lieu of the 2021 annual meeting of stockholders (the “STPC Special Meeting”) to consider matters relating to the proposed merger. STPC and Benson Hill cannot complete the merger unless STPC’s stockholders consent to the approval of the merger agreement and the transactions contemplated thereby, including the issuance of New Benson Hill Common Stock to be issued as the merger consideration, and Benson Hill’s stockholders consent to adoption and approval of the merger agreement and the transactions contemplated thereby. STPC and Benson Hill are sending you this proxy statement/prospectus to ask you to vote in favor of these and the other matters described in this proxy statement/prospectus.

The STPC Special Meeting will be held on            , 2021, at         Eastern Time, via a virtual meeting. In light of the novel coronavirus disease (referred to as “COVID-19”) pandemic and to support the well-being of STPC’s stockholders and partners, the STPC Special Meeting will be completely virtual. You may attend the meeting and vote your shares electronically during the meeting via live audio webcast by visiting https://www.cstproxy.com/starpeakcorpii/2021. You will need the control number that is printed on your proxy card to enter the STPC Special Meeting. STPC recommends that you log in at least 15 minutes before the meeting to ensure you are logged in when the STPC Special Meeting starts. Please note that you will not be able to attend the STPC Special Meeting in person.

YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF SHARES OF CLASS A COMMON STOCK YOU OWN. To ensure your representation at the STPC Special Meeting, please complete and return the enclosed proxy card or submit your proxy by following the instructions contained in this proxy statement/prospectus and on your proxy card. Please submit your proxy promptly whether or not you expect to attend the meeting. Submitting a proxy now will NOT prevent you from being able to vote online at the meeting. If you hold your shares in “street name,” you should instruct your broker, bank or other nominee how to vote in accordance with the voting instruction form you receive from your broker, bank or other nominee.

The STPC board of directors has unanimously approved the merger agreement and the transactions contemplated thereby and recommends that STPC stockholders vote “FOR” the approval of the merger agreement, “FOR” the issuance of New Benson Hill Common Stock to be issued as the merger consideration and “FOR” the other matters to be considered at the STPC Special Meeting.

This proxy statement/prospectus provides you with detailed information about the proposed merger. It also contains or references information about STPC and Benson Hill and certain related matters. You are encouraged to read this proxy statement/prospectus carefully. In particular, you should read the “Risk Factors” section beginning on page 26 for a discussion of the risks you should consider in evaluating the proposed merger and how it will affect you.

Sincerely,

/s/ Eric Scheyer

Any representation to the contrary is a criminal offense.

This proxy statement/prospectus is dated            , 2021, and is first being mailed to stockholders of STPC on or about            , 2021.

NOTICE IS HEREBY GIVEN that a special meeting in lieu of the 2021 annual meeting of the stockholders (the “STPC Special Meeting”), of Star Peak Corp II, a Delaware corporation (which is referred to as “STPC”) will be held virtually, conducted via live audio webcast at https://www.cstproxy.com/starpeakcorpii/2021,      Eastern Time, on      , 2021. You will need the control number that is printed on your proxy card to enter the STPC Special Meeting. STPC recommends that you log in at least 15 minutes before the STPC Special Meeting to ensure you are logged in when the meeting starts. Please note that you will not be able to attend the STPC Special Meeting in person. You are cordially invited to attend the STPC Special Meeting for the following purposes:

1.

The Business Combination Proposal — To consider and vote upon a proposal to approve and adopt the Agreement and Plan of Merger, dated as of May 8, 2021 (as it may be amended and/or restated from time to time, the “merger agreement”), by and among STPC, STPC II Merger Sub Corp., a Delaware corporation and wholly-owned subsidiary of STPC (“Merger Sub”), and Benson Hill, Inc., a Delaware corporation (“Benson Hill”), and to approve the transactions contemplated thereby. If the merger agreement is adopted by Benson Hill’s stockholders, the merger agreement and the transactions contemplated thereby, including the issuance of common stock of STPC (“New Benson Hill Common Stock”) to be issued as the merger consideration, is approved by STPC’s stockholders, and the merger is subsequently completed, Merger Sub will merge with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC (the “merger”). A copy of the merger agreement is attached to this proxy statement/prospectus as Annex A (Proposal No. 1);

2.

The Charter Proposals — To consider and vote upon (collectively, the “Charter Proposals”):

a.

separate proposals to approve the following amendments to STPC’s current amended and restated certificate of incorporation (the “Existing Charter”) as set forth in the proposed second amended and restated certificate of incorporation of STPC (the “Proposed Charter”) that will be in effect upon the closing of the merger (the “closing”), a copy of which is attached to this proxy statement/​prospectus as Annex B:

i.

to eliminate the Class B Common Stock classification and provide for a single class of common stock (Proposal No. 2);

ii.

to provide that amendments to STPC’s waiver of corporate opportunities will be prospective only and provide certain other clarificatory amendments to the waiver of corporate opportunities provision (Proposal No. 3);

iii.

to provide that, prior to            , 2024, the affirmative vote of at least 662∕3% of the voting power of the outstanding shares of capital stock outstanding and entitled to vote thereon, voting together as a single class, shall be required to (A) adopt, amend or repeal the bylaws by action of the stockholders of New Benson Hill, or (B) to amend or repeal any provision of the Proposed Charter in Article V (Board of Directors), Article VI (Amendment of the Governing Documents) Article VII (Stockholder Action), Article VIII (Limitation of Director Liability and Indemnification), Article IX (Business Combinations), Article X (Corporate Opportunity), Article XI (Forum Selection) or Article XII (Miscellaneous) (Proposal No. 4); and

b.

conditioned upon the approval of Proposals No. 2 through No. 4 above, a proposal to approve the Proposed Charter, which includes the approval of all other changes in the Proposed Charter in connection with replacing the Existing Charter with the Proposed Charter, including changing STPC’s name from “Star Peak Corp II” to “Benson Hill, Inc.” as of the closing of the merger (Proposal No. 5);

3.

The NYSE Proposal — To consider and vote upon a proposal to approve, for purposes of complying with applicable listing rules of the New York Stock Exchange (the “NYSE”): (i) the issuance of shares of New Benson Hill Common Stock immediately following the consummation of the merger, pursuant

to the PIPE Agreements (as defined herein); (ii) the issuance of shares of New Benson Hill Common Stock pursuant to the merger agreement; and (iii) the related change of control of STPC that will occur in connection with consummation of the merger and the other transactions contemplated by the merger agreement and PIPE Agreements (Proposal No. 6);

4.

The Incentive Plan Proposal — To consider and vote upon a proposal to approve and adopt the Incentive Plan (as defined herein) (Proposal No. 7); and

5.

The Adjournment Proposal — To consider and vote upon a proposal to adjourn the STPC Special Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the STPC Special Meeting, there are not sufficient votes to approve the Business Combination Proposal, the Charter Proposals, the NYSE Proposal or the Incentive Plan Proposal, or holders of STPC’s Class A Common Stock have elected to redeem an amount of Class A Common Stock such that STPC would have less than $5,000,001 of net tangible assets (Proposal No. 8).

Only holders of record of Class A Common Stock and Class B Common Stock (each as defined herein) at the close of business on            , 2021 are entitled to notice of the STPC Special Meeting and to vote at the STPC Special Meeting and any adjournments or postponements of the STPC Special Meeting. A complete list of STPC stockholders of record entitled to vote at the STPC Special Meeting will be available for ten (10) days before the STPC Special Meeting at the principal executive offices of STPC for inspection by stockholders during ordinary business hours for any purpose germane to the STPC Special Meeting. The eligible STPC stockholder list will also be available at that time on the STPC Special Meeting website for examination by any stockholder attending the STPC Special Meeting live audio webcast.

Pursuant to STPC’s Existing Charter, STPC will provide holders (“public stockholders”) of its Class A Common Stock, par value $0.0001 per share (“Class A Common Stock”) with the opportunity to redeem their shares of Class A Common Stock for cash equal to their pro rata share of the aggregate amount on deposit in the trust account (the “Trust Account”), which holds the proceeds of STPC’s initial public offering (“IPO”) as of two (2) business days prior to the consummation of the transactions contemplated by the Business Combination Proposal (including interest earned on the funds held in the Trust Account and not previously released to STPC to pay taxes) upon the closing of the transactions contemplated by the merger agreement. For illustrative purposes, based on funds in the Trust Account of approximately $402.6 million on June 30, 2021, the estimated per share redemption price would have been approximately $10.00, excluding additional interest earned on the funds held in the Trust Account and not previously released to STPC to pay taxes. Public stockholders may elect to redeem their shares even if they vote for the Business Combination Proposal. A public stockholder, together with any of his, her or its affiliates or any other person with whom he, she or it is acting in concert or as a “group” ​(as defined in Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to more than an aggregate of 15% of the Class A Common Stock. Star Peak Sponsor II LLC, a Delaware limited liability company (the “Sponsor”), and STPC’s officers and directors have agreed to waive their redemption rights in connection with the consummation of the merger with respect to any shares of Class A Common Stock they may hold. Currently, the Sponsor owns approximately 20% of STPC’s common stock, consisting of Class B Common Stock, par value $0.0001 per share (“Class B Common Stock” and, together with the Class A Common Stock, the “common stock”), initially purchased by the Sponsor in a private placement (together with any shares of Class A Common Stock issued upon the conversion thereof, “Founder Shares”). Founder Shares will be excluded from the pro rata calculation used to determine the per share redemption price. The Sponsor and STPC’s directors and officers have agreed to vote any shares of common stock owned by them in favor of the Business Combination Proposal.

Approval of each of the Business Combination Proposal, the NYSE Proposal and the Incentive Plan Proposal requires the affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present.

Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the then-outstanding shares of STPC common stock, voting together as a single class, and the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting separately as a single class. Approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes

cast by holders of common stock, voting together as a single class, regardless of whether a quorum is present. The STPC board of directors has already approved each of the proposals.

As of June 30, 2021, there was approximately $402.6 million in the Trust Account, which STPC intends to use for the purposes of consummating a business combination within the time period described in this proxy statement/prospectus and to pay approximately $14,087,500 in deferred underwriting commissions to the underwriters of STPC’s IPO. Each redemption of Class A Common Stock by its public stockholders will decrease the amount in the Trust Account. STPC will not consummate the merger if the redemption of Class A Common Stock would result in STPC’s failure to have at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) (or any successor rule).

If STPC stockholders fail to approve the Business Combination Proposal or the NYSE Proposal, or, unless otherwise waived by Benson Hill and STPC, the Charter Proposals or the Incentive Plan Proposal, the merger will not occur. The Charter Proposals and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal and the NYSE Proposal. The Adjournment Proposal is not conditioned on the approval of any other proposal. The proxy statement/prospectus accompanying this notice explains the merger agreement and the transactions contemplated thereby, as well as the proposals to be considered at the STPC Special Meeting. Please review the proxy statement/prospectus carefully.

The STPC board of directors has set      , 2021 as the record date for the STPC Special Meeting. Only holders of record of shares of STPC common stock at the close of business on      , 2021 will be entitled to notice of and to vote at the STPC Special Meeting and any adjournments or postponements thereof. Any stockholder entitled to attend and vote at the STPC Special Meeting may attend the meeting virtually and is entitled to appoint a proxy to attend and vote on such stockholder’s behalf. Such proxy need not be a holder of shares of STPC common stock.

YOUR VOTE IS VERY IMPORTANT, REGARDLESS OF THE NUMBER OF SHARES OF STPC COMMON STOCK YOU OWN. Whether or not you plan to attend the STPC Special Meeting, please complete, sign, date and mail the enclosed proxy card in the postage-paid envelope provided at your earliest convenience. You may also submit a proxy by telephone or via the Internet by following the instructions printed on your proxy card. If you hold your shares through a broker, bank or other nominee, you should direct the vote of your shares in accordance with the voting instruction form received from your broker, bank or other nominee.

The STPC board of directors has unanimously approved the merger agreement and the transactions contemplated thereby and recommends that you vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposals, “FOR” the NYSE Proposal and “FOR” the Incentive Plan Proposal.

If you have any questions or need assistance with voting, please contact Morrow Sodali, STPC’s proxy solicitor, toll-free at (800) 662-5200 (banks and brokers call (203) 658-9400) or email Morrow Sodali at STPC.info@investor.morrowsodali.com.

QUESTIONS AND ANSWERS

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

QUESTIONS AND ANSWERS ABOUT THE MERGER

Q:

WHAT IS THE MERGER?

A:

STPC, Merger Sub and Benson Hill have entered into an Agreement and Plan of Merger, dated as of May 8, 2021, (as it may be amended and/or restated from time to time, the “merger agreement”), pursuant to which Merger Sub will merge with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC.

STPC will hold a special meeting in lieu of the 2021 annual meeting of STPC stockholders (the “STPC Special Meeting”) to, among other things, obtain the approvals required for the merger and the other transactions contemplated by the merger agreement and you are receiving this proxy statement/prospectus in connection with such meeting. Benson Hill is also providing consent solicitation materials to the holders of Existing Benson Hill Common Stock and the holders of Benson Hill’s preferred stock, par value $0.001, designated as “Series A Preferred Stock,” “Series B Preferred Stock,” “Series C Preferred Stock” ​(including the preferred stock designated as “Series C-1 Preferred Stock”) and “Series D Preferred Stock” in its Amended and Restated Certificate of Incorporation (as amended, the “Benson Hill certificate”) (collectively, the “Benson Hill Preferred Stock”) to solicit, among other things, the required written consent to adopt and approve in all respects the merger agreement and the merger (the “Business Combination Proposal”). See “The Merger Agreement” beginning on page 171. In addition, a copy of the merger agreement is attached to this proxy statement/prospectus as Annex A. We urge you to carefully read this proxy statement/prospectus and the merger agreement in their entirety.

Q:

WHY AM I RECEIVING THIS DOCUMENT?

A:

STPC is sending this proxy statement/prospectus to its stockholders to help them decide how to vote their shares of STPC common stock with respect to the matters to be considered at the STPC Special Meeting.

The merger cannot be completed unless STPC’s stockholders approve the Business Combination Proposal, the Charter Proposals, the NYSE Proposal and the Incentive Plan Proposal, set forth in this proxy statement/prospectus. Information about the STPC Special Meeting, the merger and the other business to be considered by stockholders at the STPC Special Meeting is contained in this proxy statement/prospectus.

This document constitutes a proxy statement and a prospectus of STPC. It is a proxy statement because the board of directors of STPC is soliciting proxies using this proxy statement/prospectus from its stockholders. It is a prospectus because STPC, in connection with the merger, is offering shares of New Benson Hill Common Stock in exchange for the outstanding shares of Existing Benson Hill Common Stock. See “The Merger Agreement — Merger Consideration.”

Q:

WHAT WILL HAPPEN TO STPC’S SECURITIES UPON CONSUMMATION OF THE MERGER?

A:

STPC’s units, Class A Common Stock and public warrants are publicly traded on the NYSE under the symbols “STPC.U,” “STPC,” and “STPC WS,” respectively. Upon consummation of the merger, STPC will have one class of common stock that will be listed on the NYSE under the symbol BHIL and its warrants will be listed on the NYSE under the symbol BHIL WS. STPC will not have units traded on the NYSE following the consummation of the merger and such units will automatically be separated into their component securities without any action needed to be taken on the part of the holders. STPC warrant holders and those stockholders who do not elect to have their shares redeemed need not

vi

deliver their shares of Class A Common Stock or warrant certificates to STPC or STPC’s transfer agent and they will remain outstanding.

Q:

WHAT WILL BENSON HILL STOCKHOLDERS RECEIVE IN THE MERGER?

A:

Immediately prior to the effective time of the merger, each outstanding share of Existing Benson Hill Common Stock, including common stock held by prior owners of Benson Hill Preferred Stock (other than shares owned by Benson Hill as treasury stock and dissenting shares) will be cancelled and converted into the right to receive a pro rata portion (on a fully-diluted basis) of approximately 147,562,680 shares of New Benson Hill Common Stock (including 130,000,000 shares of New Benson Hill Common Stock, 8,781,340 $14 Earn Out Shares and 8,781,340 $16 Earn Out Shares) (including the portion of such shares of New Benson Hill Common Stock reserved for issuance upon the future exercise of any Net New Benson Hill Options and any New Benson Hill Warrants after the closing in accordance with the merger agreement). In addition to the foregoing, Earn Out Awards with a value equivalent to 2,037,320 shares of New Benson Hill Common Stock will be granted under the Incentive Plan to certain holders of Benson Hill Options. The number of Earn Out Shares and Earn Out Awards may be adjusted prior to the closing of the merger on a one-for-one basis pursuant to the terms and subject to the conditions set forth in the merger agreement such that the number of shares of New Benson Hill Common Stock issued as Earn Out Shares or being reserved for or subject to the Earn Out Awards granted shall not exceed 19,600,000 shares of New Benson Hill Common Stock in the aggregate. In addition, a portion of the New Benson Hill Common Stock shares reserved for issuance under the Incentive Plan shall be used for the Exercise Price Options.

Subject to the assumptions set forth under “Basis of Presentation and Glossary” in the accompanying proxy statement/prospectus and assuming that the merger effective date were            , 2021, the record date for the STPC Special Meeting (as defined below), the exchange ratio would have been approximately            of a share of New Benson Hill Common Stock for each share of Existing Benson Hill Common Stock (assuming for purposes of such calculation that all outstanding shares of Benson Hill Preferred Stock have converted into Existing Benson Hill Common Stock), except for any resulting fractional shares of New Benson Hill Common Stock (which will instead be paid in cash in an amount equal to the fractional amount multiplied by $10.00).

Q:

WILL HOLDERS OF EXISTING BENSON HILL COMMON STOCK BE SUBJECT TO U.S. FEDERAL INCOME TAX ON THE NEW BENSON HILL COMMON STOCK RECEIVED IN THE MERGER?

A:

As discussed more fully under the Section titled “Material U.S. Federal Income Tax Consequences,” subject to the qualifications and limitations discussed thereunder, the merger should qualify as a “reorganization” within the meaning of Section 368(a). However, such position is not binding upon the Internal Revenue Service (the “IRS”) or the courts, and there can be no assurance that the IRS or a court will not take a contrary position. Benson Hill and STPC do not intend to request a ruling from the IRS regarding any aspect of the U.S. federal income tax consequences of the merger. Subject to the qualifications and limitations set forth in “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders” and ‘‘— Tax Consequences to Non-U.S. Holders,’’ if the merger qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, holders of Existing Benson Hill Common Stock will generally not recognize any gain or loss as a result of the merger. For more information on the material U.S. federal income tax consequences of the merger to holders of Existing Benson Hill Common Stock, see “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Tax Consequences of the Merger to U.S. Holders of Existing Benson Hill Common Stock” and “Material U.S. Federal Income Tax Consequences — Tax Consequences to Non-U.S. Holders — U.S. Federal Income Tax Consequences of the Merger to Non-U.S. Holders of Existing Benson Hill Common Stock’’ below. Holders of Existing Benson Hill Common Stock are urged to consult their tax advisors to determine the tax consequences to them (including the application and effect of any state, local or other income and other tax laws) of the merger.

Q:

WHEN WILL THE MERGER BE COMPLETED?

A:

The parties currently expect that the merger will be completed during the third quarter of 2021.

vii

However, neither STPC nor Benson Hill can assure you of when or if the merger will be completed and it is possible that factors outside of the control of both companies could result in the merger being completed at a different time or not at all. STPC must first obtain the approval of STPC stockholders for each of the proposals set forth in this proxy statement/prospectus for their approval (other than the Adjournment Proposal) and STPC and Benson Hill must also first obtain certain necessary regulatory approvals and satisfy other closing conditions. See “The Merger Agreement — Conditions to the Merger” beginning on page 184.

Q:

WHAT HAPPENS TO BENSON HILL STOCKHOLDERS IF THE MERGER IS NOT COMPLETED?

A:

If the merger is not completed, Benson Hill stockholders will not receive any consideration for their shares of Existing Benson Hill Common Stock, and such shares will not be converted into STPC common stock.

Instead, Benson Hill will remain an independent company. See “The Merger Agreement — Termination” and “Risk Factors” beginning on page 185 and page 26, respectively.

QUESTIONS AND ANSWERS ABOUT THE STPC SPECIAL MEETING

Q:

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

A:

STPC stockholders are being asked to vote on the following proposals:

1.

Proposal No. 1 — The Business Combination Proposal: To approve the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A, and the transactions contemplated thereby, including the merger of Merger Sub with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC, and the issuance of New Benson Hill Common Stock to Benson Hill equity holders as merger consideration;

2.

Proposals No. 2 through No. 5 — The Charter Proposals:

a.

separate proposals to approve the following amendments to STPC’s Existing Charter, as set forth in the proposed second amended and restated certificate of incorporation of STPC (the “Proposed Charter”), a copy of which is attached to this proxy statement/prospectus as Annex B, that will be in effect upon the closing of the merger:

i.

to eliminate the Class B Common Stock classification and provide for a single class of common stock (Proposal No. 2);

ii.

to provide that amendments to STPC’s waiver of corporate opportunities will be prospective only and provide certain other clarificatory amendments to the waiver of corporate opportunities provision (Proposal No. 3);

iii.

to provide that, prior to           , 2024, the affirmative vote of at least 662∕3% of the voting power of the outstanding shares of capital stock outstanding and entitled to vote thereon, voting together as a single class, shall be required to (A) adopt, amend or repeal the bylaws by action of the stockholders of New Benson Hill, or (B) to amend or repeal any provision of the Proposed Charter in Article V (Board of Directors), Article VI (Amendment of the Governing Documents) Article VII (Stockholder Action), Article VIII (Limitation of Director Liability and Indemnification), Article IX (Business Combinations), Article X (Corporate Opportunity), Article XI (Forum Selection) or Article XII (Miscellaneous) (Proposal No. 4); and

b.

conditioned upon the approval of Proposals No. 2 through No. 4 above, to approve the Proposed Charter, which includes the approval of all other changes in the Proposed Charter in connection with replacing the Existing Charter with the Proposed Charter, including changing STPC’s name from “Star Peak Corp II” to “Benson Hill, Inc.” as of the closing of the merger (Proposal No. 5);

viii

3.

Proposal No. 6 — The NYSE Proposal: To approve, for purposes of complying with applicable listing rules of the NYSE: (i) the issuance of shares of New Benson Hill Common Stock immediately following the consummation of the merger, pursuant to the PIPE Agreements; (ii) the issuance of shares of New Benson Hill Common Stock pursuant to the merger agreement; and (iii) the related change of control of STPC that will occur in connection with consummation of the merger and the other transactions contemplated by the merger agreement and PIPE Agreements;

4.

Proposal No. 7 — The Incentive Plan Proposal: To approve and adopt the Incentive Plan; and

5.

Proposal No. 8 — The Adjournment Proposal: To approve the adjournment of the STPC Special Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if, based upon the tabulated vote at the time of the STPC Special Meeting, there are not sufficient votes to approve the Business Combination Proposal, the Charter Proposals, the NYSE Proposal or the Incentive Plan Proposal, or holders of STPC’s Class A Common Stock have elected to redeem an amount of Class A Common Stock such that STPC would have less than $5,000,001 of net tangible assets.

The adoption of the Business Combination Proposal is required under Delaware law and the approval of the merger is required under STPC’s Existing Charter. The approval of the NYSE Proposal is required under NYSE Rules. In addition, approval of such proposals by STPC stockholders is also a condition to the closing of the merger under the merger agreement.

If STPC stockholders fail to approve the Business Combination Proposal or the NYSE Proposal, or, unless otherwise waived by Benson Hill and STPC, the Charter Proposals or the Incentive Plan Proposal, the merger will not occur.

Q:

ARE THE PROPOSALS CONDITIONED UPON ONE ANOTHER?

A:

The Charter Proposals and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal and the NYSE Proposal. Additionally, Proposal No. 5 is conditioned upon the approval of the other Charter Proposals (Proposals No. 2 through No. 4). The Adjournment Proposal is not conditioned on the approval of any other proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the stockholders for a vote.

It is important to note that if STPC stockholders fail to approve the Business Combination Proposal or the NYSE Proposal, or, unless otherwise waived by Benson Hill and STPC, the Charter Proposals or the Incentive Plan Proposal, the merger will not occur.

Q:

WHY IS STPC PROPOSING THE MERGER?

A:

STPC was organized to effect a merger, capital stock exchange, asset acquisition, share purchase, reorganization or other similar business combination with one or more businesses (collectively, a “business combination”).

On January 8, 2021, STPC completed its initial public offering (“IPO”). A total of $402,500,000, comprised of $394,450,000 of the proceeds from STPC’s IPO (including aggregate fees of approximately $14.1 million as deferred underwriting commissions) and $8,050,000 of the proceeds from the concurrent sale of the Private Placement Warrants, were placed in a trust account (the “Trust Account”). Since STPC’s IPO, STPC’s activity has been limited to the evaluation of business combination candidates.

Benson Hill is a values-driven food technology company with a vision to build a healthier and happier world by unlocking nature’s genetic diversity with their food innovation engine. Their purpose is to catalyze and broadly empower innovation from plant to plate so great tasting, healthy, affordable, and sustainable food choices are available to everyone. The Company combines cutting-edge technology with an innovative business approach to bring product innovations to customers and consumers. Their CropOS® technology platform uniquely combines data science, plant science, and food science to create innovative food, ingredient, and feed products — starting with a better seed. Their go-to-market

ix

strategy consists of building an integrated supply chain to catalyze demand for their proprietary products, which they believe will allow them to establish partnerships and licensing arrangements to drive broad adoption. The Company believes this approach will allow them not only to ensure the integrity and traceability of their products, but also to measure the positive environmental impact created by their innovations.

Today, their business is comprised of two segments — their Ingredients Business and their Fresh Business. Their Ingredients Business is currently focused on enhancing soybean and yellow pea products, including soy-based vegetable oils, animal feed, and ultra high protein (UHP) soybeans that have the potential to reduce costly water- and energy-intensive processing associated with producing protein concentrates and isolates, alleviating supply constraints to help bring plant-based proteins to scale. Their Fresh Business is being built to serve the growing consumer interest in the convergence between food and health. Today this segment includes their subsidiary, J&J Produce, Inc., where they sell fresh produce products to major retail and food service customers. They have initiated the establishment of research and development operations where they intend to use their CropOS® platform to unlock flavor, nutrition, and sustainability benefits in fresh produce over the long-term.

Based on its due diligence investigations of Benson Hill and the industry in which it operates, including the financial and other information provided by Benson Hill in the course of their negotiations in connection with the merger agreement, STPC believes that Benson Hill aligns well with the objectives laid out in its investment thesis which focused on identifying a business that is a market leader in, and/or benefitting from the increasing global initiatives to improve sustainability and/or reduce global emissions.

Consistent with STPC’s objectives, Benson Hill’s mission is to create food made better from the beginning. As a result, STPC believes that a merger with Benson Hill will provide STPC stockholders with an opportunity to participate in the ownership of a publicly-listed company with significant growth potential at an attractive valuation. See the section entitled “The Merger — Recommendation of the STPC Board of Directors and Reasons for the Merger.”

Q:

DID THE STPC BOARD OBTAIN A THIRD-PARTY VALUATION OR FAIRNESS OPINION IN DETERMINING WHETHER OR NOT TO PROCEED WITH THE MERGER?

A:

STPC’s board of directors did not obtain a third-party valuation or fairness opinion in connection with their determination to approve the merger. STPC’s officers, directors and advisors have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and backgrounds, together with the experience and sector expertise of STPC’s financial advisors, enabled them to make the necessary analyses and determinations regarding the merger. In addition, STPC’s officers, directors and advisors have substantial experience with mergers and acquisitions. Accordingly, investors will be relying solely on the judgment of STPC’s board of directors and advisors in valuing Benson Hill’s business.

Q:

DO I HAVE REDEMPTION RIGHTS?

A:

If you are a holder of Class A Common Stock, you have the right to demand that STPC redeem such shares for a pro rata portion of the cash held in the Trust Account, which holds the proceeds of STPC’s IPO, as of two (2) business days prior to the consummation of the transactions contemplated by the Business Combination Proposal (including interest earned on the funds held in the Trust Account and not previously released to STPC to pay taxes) upon the closing of the transactions contemplated by the merger agreement (such rights, “redemption rights”).

Notwithstanding the foregoing, a holder of Class A Common Stock, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group” ​(as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption with respect to more than 15% of the Class A Common Stock. Accordingly, no shares of Class A Common Stock in excess of 15% held by a public stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will be redeemed.

x

Holders of the outstanding public warrants of STPC do not have redemption rights with respect to such warrants in connection with the transactions contemplated by the Business Combination Proposal.

Under STPC’s Existing Charter, the merger may be consummated only if STPC has at least $5,000,001 of net tangible assets after giving effect to all holders of Class A Common Stock that properly demand redemption of their shares for cash.

Q:

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

A:

No. You may exercise your redemption rights whether you vote your shares of Class A Common Stock for or against, or whether you abstain from voting on, the Business Combination Proposal or any other proposal described in this proxy statement/prospectus. As a result, the Business Combination Proposal can be approved by stockholders who will redeem their Class A Common Stock and no longer remain stockholders and the merger may be consummated even though the funds available from the Trust Account and the number of public stockholders are substantially reduced as a result of redemptions by public stockholders. With fewer shares of Class A Common Stock and public stockholders, the trading market for Class A Common Stock may be less liquid than the market for Class A Common Stock prior to the merger and STPC may not be able to meet the listing standards of a national securities exchange. In addition, with fewer funds available from the Trust Account, the capital infusion from the Trust Account into New Benson Hill’s business will be reduced and the amount of working capital available to New Benson Hill following the merger may be reduced. Your decision to exercise your redemption rights with respect to shares of Class A Common Stock will have no effect on public warrants of STPC you may also hold.

Q:

HOW DO I EXERCISE MY REDEMPTION RIGHTS?

A:

If you are a holder of Class A Common Stock and wish to exercise your redemption rights, you must demand that STPC redeem your shares for cash no later than 5:00 p.m., Eastern Time, on the second business day preceding the vote on the Business Combination Proposal by delivering your stock to STPC’s transfer agent physically or electronically using Depository Trust Company’s DWAC (Deposit and Withdrawal at Custodian) system prior to the vote at the STPC Special Meeting. Any holder of Class A Common Stock will be entitled to demand that such holder’s shares be redeemed for a full pro rata portion of the amount then in the Trust Account (which, for illustrative purposes, was approximately $402.6 million, or $10.00 per share, as of June 30, 2021). Such amount, including interest earned on the funds held in the Trust Account and not previously released to STPC to pay its taxes, will be paid promptly upon consummation of the merger. However, under Delaware law, the proceeds held in the Trust Account could be subject to claims that could take priority over those of STPC’s public stockholders exercising redemption rights, regardless of whether such holders vote for or against the Business Combination Proposal. Therefore, the per share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. Your vote on any proposal other than the Business Combination Proposal will have no impact on the amount you will receive upon exercise of your redemption rights.

Any request for redemption, once made by a holder of Class A Common Stock, may be withdrawn at any time up to the time the vote is taken with respect to the Business Combination Proposal at the STPC Special Meeting. If you deliver your shares for redemption to STPC’s transfer agent and later decide prior to the STPC Special Meeting not to elect redemption, you may request that STPC’s transfer agent return the shares (physically or electronically).

Any corrected or changed proxy card or written demand of redemption rights must be received by STPC’s transfer agent prior to the vote taken on the Business Combination Proposal at the STPC Special Meeting. No demand for redemption will be honored unless the holder’s stock has been delivered (either physically or electronically) to the transfer agent no later than 5:00 p.m., Eastern Time, on the second business day prior to the vote at the STPC Special Meeting.

If a holder of Class A Common Stock properly makes a request for redemption and the shares of Class A Common Stock are delivered as described to STPC’s transfer agent as described herein, then, if the merger is consummated, STPC will redeem these shares for a pro rata portion of funds deposited

xi

in the Trust Account. If you exercise your redemption rights, then you will be exchanging your shares of Class A Common Stock for cash.

For a discussion of the material U.S. federal income tax considerations for holders of Class A Common Stock with respect to the exercise of these redemption rights, see “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders” beginning on page 205 and "Material U.S. Federal Income Tax Consequences — Tax Consequences to Non-U.S. Holders" beginning on page 209.

Q:

HOW DO REDEMPTIONS AFFECT THE VALUE OF MY NEW BENSON HILL COMMON STOCK?

A:

The value of shares of New Benson Hill Common Stock held by a non-redeeming STPC public stockholder may be impacted by the number of shares that are redeemed, as well as other events that may significantly dilute the value of such shares of New Benson Hill Common Stock. For example, the following table shows the potential impact of varying levels of redemptions and certain dilutive events on the per share value of the New Benson Hill Common Stock held by non-redeeming STPC public stockholders, in each case assuming an enterprise value of $1.35 billion for New Benson Hill upon consummation of the merger (which assumed enterprise valuation does not include the Exercise Price Options, which accordingly are not reflected in the table below).

The foregoing table is provided for illustrative purposes only and there can be no assurance that the New Benson Hill Common Stock will trade at the illustrative per share values set forth therein, regardless of the levels of redemption. See ‘‘Risk Factors — Additional Risks Relating to Ownership of New Benson Hill Common Stock Following the Merger — New Benson Hill’s stock price may change significantly following the merger and you could lose all or part of your investment as a result.’’ Further, we have not received any indications from stockholders regarding their intentions to redeem or retain their shares of Class A Common Stock upon consummation of the merger and have not formulated any expectation as to which, if any, of the illustrative scenarios included in the foregoing table is most likely.

Q:

WHAT HAPPENS TO THE FUNDS DEPOSITED IN THE TRUST ACCOUNT AFTER CONSUMMATION OF THE MERGER?

A:

The net proceeds of STPC’s IPO, together with funds raised from the private sale of warrants simultaneously with the consummation of STPC’s IPO, were placed in the Trust Account immediately following STPC’s IPO. After consummation of the merger, the funds in the Trust Account will be used to pay holders of the Class A Common Stock who exercise redemption rights, to pay fees and expenses incurred in connection with the merger (including aggregate fees of approximately $14,087,500 as deferred underwriting commissions related to STPC’s IPO) and for New Benson Hill’s working capital and general corporate purposes, which may include future strategic transactions.

Q:

WHAT HAPPENS IF THE MERGER IS NOT CONSUMMATED?

A:

If STPC does not complete the merger with Benson Hill for any reason, STPC would search for another target business with which to complete a business combination. If STPC does not complete the merger with Benson Hill or another target business by January 8, 2023, STPC must redeem 100% of the outstanding shares of Class A Common Stock, at a per share price, payable in cash, equal to the amount then held in the Trust Account divided by the number of outstanding shares of Class A Common Stock. The Sponsor has no redemption rights in the event a business combination is not effected in the required time period and, accordingly, its Founder Shares (as defined herein) will be worthless. Additionally, in the event of such liquidation, there will be no distribution with respect to STPC’s outstanding warrants. Accordingly, such warrants will expire worthless.

Q:

HOW DOES THE SPONSOR INTEND TO VOTE ON THE PROPOSALS?

A:

The Sponsor owns of record and is entitled to vote an aggregate of approximately 20% of the outstanding shares of STPC common stock. Pursuant to an agreement among the Sponsor, STPC’s officers and directors have entered into an agreement with STPC (the “Letter Agreement”), the Sponsor has agreed to vote any Founder Shares and any shares of Class A Common Stock held by it as of the STPC record date, in favor of the proposals. See “Other Agreements — STPC Letter Agreement,” beginning on page 188 of this proxy statement/prospectus.

Q:

WHAT CONSTITUTES A QUORUM AT THE STPC SPECIAL MEETING?

A:

A majority of the voting power of the issued and outstanding STPC common stock entitled to vote at the STPC Special Meeting as of the STPC record date must be present virtually or by proxy, at the STPC Special Meeting to constitute a quorum and in order to conduct business at the STPC Special Meeting. Abstentions and broker non-votes will be counted as present for the purpose of determining a quorum. The holders of the Founder Shares, who currently own approximately 20% of the issued and outstanding shares of STPC common stock, will count towards this quorum. In the absence of a quorum,

xiii

the chairman of the STPC Special Meeting has power to adjourn the STPC Special Meeting. As of the STPC record date,        shares of STPC common stock would be required to achieve a quorum.

Q:

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

A:

Proposal No. 1 — The Business Combination Proposal:   The affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present, is required to approve the Business Combination Proposal. Accordingly, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have no effect on the Business Combination Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Business Combination Proposal.

Proposals No. 2 through No. 5 — The Charter Proposals:   The affirmative vote of the holders of a majority of the then-outstanding shares of STPC common stock, voting together as a single class, and the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting separately as a single class, is required to approve the Charter Proposals. Accordingly, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have the same effect as a vote “AGAINST” each of the Charter Proposals.

Proposal No. 6 — The NYSE Proposal:   The affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present, is required to approve the NYSE Proposal. Accordingly, under Delaware law, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have no effect on the NYSE Proposal. For purposes of NYSE rules, however, abstentions are treated as “votes cast” and will be counted as votes “AGAINST” this proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

Proposal No. 7 — The Incentive Plan Proposal:   The affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present, is required to approve the Incentive Plan Proposal. Accordingly, under Delaware law, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have no effect on the Incentive Plan Proposal. For purposes of NYSE rules, however, abstentions are treated as “votes cast” and will be counted as votes “AGAINST” this proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established.

Proposal No. 8 — The Adjournment Proposal:   The affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class, regardless of whether a quorum is present, is required to approve the Adjournment Proposal. Accordingly, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have no effect on the Adjournment Proposal. Abstentions will be counted in connection with the determination of whether a valid quorum is established but will have no effect on the Adjournment Proposal.

Q:

DO ANY OF STPC’S DIRECTORS OR OFFICERS HAVE INTERESTS IN THE MERGER THAT MAY DIFFER FROM OR BE IN ADDITION TO THE INTERESTS OF STPC STOCKHOLDERS?

A:

STPC’s executive officers and certain non-employee directors may have interests in the merger that may be different from, or in addition to, the interests of STPC stockholders generally. The STPC board of directors was aware of and considered these interests to the extent such interests existed at the time, among other matters, in approving the merger agreement and in recommending that the merger agreement and the transactions contemplated thereby be approved by the stockholders of STPC. See “The Merger — Interests of STPC’s Directors and Executive Officers in the Merger” beginning on page 166 of this proxy statement/prospectus.

Q:

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

Q:

WHEN AND WHERE IS THE STPC SPECIAL MEETING?

A:

The STPC Special Meeting of stockholders will be held on            , 2021, unless postponed or adjourned to a later date. In light of the novel coronavirus disease (referred to as “COVID-19”) pandemic and to support the well-being of STPC’s stockholders and partners, the STPC Special Meeting will be completely virtual. All STPC stockholders as of the STPC record date, or their duly appointed proxies, may attend the STPC Special Meeting. Registration will begin at       Eastern Time.

Q:

HOW CAN STPC’S STOCKHOLDERS ATTEND THE SPECIAL MEETING?

A:

As a registered stockholder, you received a Notice and Access instruction form or proxy card from Continental Stock Transfer & Trust Company (“CST”). Both forms contain instructions on how to attend the virtual STPC Special Meeting including the URL address, along with your control number. You will need your control number for access. If you do not have your control number, contact CST at the phone number or e-mail address below. CST’s contact information is as follows: +1 (917) 262-2373, or email proxy@continentalstock.com.

Q:

WHY IS THE SPECIAL MEETING A VIRTUAL MEETING?

A:

STPC has decided to hold the STPC Special Meeting virtually due to the COVID-19 pandemic; STPC is sensitive to the public health and travel concerns of STPC’s stockholders and employees and the protocols that federal, state and local governments may impose. STPC believes that hosting a virtual meeting will enable greater stockholder attendance and participation from any location around the world.

Q:

WHAT IF DURING THE CHECK-IN TIME OR DURING THE SPECIAL MEETING I HAVE TECHNICAL DIFFICULTIES OR TROUBLE ACCESSING THE VIRTUAL MEETING WEBSITE?

A:

If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support number that will be posted on the virtual stockholder meeting log in page.

Q:

WHAT IS THE DIFFERENCE BETWEEN A STOCKHOLDER OF RECORD AND A “STREET NAME” HOLDER?

A:

If your shares are registered directly in your name with STPC’s transfer agent, CST, you are considered the stockholder of record with respect to those shares, and access to proxy materials is being provided directly to you. If your shares are held in a stock brokerage account or by a bank or other nominee, then you are considered the beneficial owner of those shares, which are considered to be held in “street name.” Access to proxy materials is being provided to you by your broker, bank or other nominee who is considered the stockholder of record with respect to those shares.

Q:

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

A:

If your shares are held in “street name” in a stock brokerage account or by a broker, bank or other nominee, you must provide the record holder of your shares with instructions on how to vote your shares.

Please follow the voting instructions provided by your broker, bank or other nominee. Please not that you may not vote shares held in “street name” by returning a proxy card directly to STPC or by voting online at the STPC Special Meeting unless you provide a “legal proxy,” which you must obtain from your broker, bank or other nominee.

Under the rules of the NYSE, brokers who hold shares in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers are not permitted to exercise their voting discretion with respect to the approval of matters that the NYSE determines to be “non-routine” without specific instructions from the beneficial owner. We believe the proposals presented to the stockholders at the STPC Special Meeting will be considered non-routine and, therefore, your broker, bank, or other nominee cannot vote your shares without your instruction on any of the proposals presented at the STPC Special Meeting. If you do not submit voting instructions, your broker, bank, or other nominee may deliver a proxy card expressly indicating that it is NOT voting your shares; this indication that a broker, bank, or nominee is not voting your shares is referred to as a “broker non-vote.” Broker non-votes will not be counted for the purposes of determining the existence of a quorum or for purposes of determining the number of votes cast at the Special Meeting. Your bank, broker, or other nominee can vote your shares only if you provide instructions on how to vote. You should instruct your broker to vote your shares in accordance with directions you provide.

A broker non-vote will be the equivalent of a vote “AGAINST” the Charter Proposals, but will not have any effect on the outcome of any other proposals.

xvi

Q:

WHAT HAPPENS IF I SELL MY SHARES OF CLASS A COMMON STOCK BEFORE THE STPC SPECIAL MEETING?

A:

The record date for the STPC Special Meeting will be earlier than the date of the consummation of the merger. If you transfer your shares of Class A Common Stock after the record date, but before the STPC Special Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the STPC Special Meeting. However, you will not be able to seek redemption of your shares of Class A Common Stock because you will no longer be able to deliver them for cancellation upon the consummation of the merger in accordance with the provisions described herein.

If you transfer your shares of Class A Common Stock prior to the STPC record date, you will have no right to vote those shares at the STPC Special Meeting or redeem those shares for a pro rata portion of the proceeds held in the Trust Account.

Q:

WHAT ARE THE RECOMMENDATIONS OF THE STPC BOARD OF DIRECTORS?

A:

The STPC board of directors believes that the Business Combination Proposal and the other proposals to be presented at the STPC Special Meeting are in the best interest of STPC and its stockholders and unanimously recommends that STPC’s stockholders vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposals, “FOR” the NYSE Proposal, “FOR” the Incentive Plan Proposal, and “FOR” the Adjournment Proposal (if necessary).

Q:

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

A:

If you sign and return your proxy card without indicating how to vote on any particular proposal, the STPC stock represented by your proxy will be voted as recommended by the STPC board of directors with respect to that proposal.

Q:

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

A:

At the STPC Special Meeting, we will count a properly executed proxy marked “ABSTAIN” with respect to a particular proposal as present for purposes of determining whether a quorum is present.

For purposes of approval, a failure to vote or an abstention will have no effect on the Business Combination Proposal and the Adjournment Proposal. However, an abstention or failure to vote will have the same effect as a vote “AGAINST” the Charter Proposals. In addition, for purposes of the NYSE Proposal and the Incentive Plan Proposal, the NYSE considers an abstention vote as a “vote cast”, and therefore, an abstention will have the same effect as a vote “AGAINST” such proposals, while a failure to vote will have no effect on these two proposals.

Q:

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

A:

Yes. You may change your vote at any time before your proxy is voted at the STPC Special Meeting.

You may do this in one of three ways:

•

filing a notice with the corporate secretary of STPC;

•

mailing a new, subsequently dated proxy card; or

•

by attending the STPC Special Meeting virtually and electing to vote your shares online.

If you are a stockholder of record of STPC and you choose to send a written notice or to mail a new proxy, you must submit your notice of revocation or your new proxy to Star Peak Corp II, 1603 Orrington Avenue, 13th Floor, Evanston, Illinois 60201, and it must be received at any time before the vote is taken at the STPC Special Meeting. Any proxy that you submitted may also be revoked by submitting a new proxy by mail, or online or by telephone, not later than 11:59 p.m. Eastern Time on            , 2021, or by voting online at the STPC Special Meeting. Simply attending the STPC Special Meeting will not revoke your proxy. If you have instructed a broker, bank or other nominee to vote your shares of

xvii

STPC common stock, you must follow the directions you receive from your broker, bank or other nominee in order to change or revoke your vote.

Q:

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

A:

If you fail to take any action with respect to the STPC Special Meeting and the merger is approved by stockholders and consummated, you will continue to be a stockholder of STPC. Failure to take any action with respect to the STPC Special Meeting will not affect your ability to exercise your redemption rights. If you fail to take any action with respect to the STPC Special Meeting and the merger is not approved, you will continue to be a stockholder of STPC while STPC searches for another target business with which to complete a business combination.

Q:

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

A:

Stockholders may receive more than one (1) set of voting materials, including multiple copies of this proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold your shares in more than one (1) brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold shares. If you are a holder of record and your shares are registered under more than one (1) name, you will receive more than one (1) proxy card. Please complete, sign, date and return each proxy card and voting instruction card that you receive in order to cast a vote with respect to all of your shares.

Q:

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

A:

If you have any questions about the proxy materials, need assistance submitting your proxy or voting your shares or need additional copies of this proxy statement/prospectus or the enclosed proxy card, you should contact Morrow Sodali, STPC’s proxy solicitor, toll-free at (800) 662-5200 (banks and brokers call (203) 658-9400) or email Morrow Sodali at STPC.info@investor.morrowsodali.com.

SUMMARY

This summary highlights selected information included in this proxy statement/prospectus and does not contain all of the information that may be important to you. You should read this entire document and its annexes and the other documents to which we refer before you decide how to vote. Each item in this summary includes a page reference directing you to a more complete description of that item.

The Merger and the Merger Agreement (pages 147 and 171)

The terms and conditions of the merger are contained in the merger agreement, which is attached as Annex A to this proxy statement/prospectus. We encourage you to read the merger agreement carefully, as it is the legal document that governs the merger.

If the merger agreement is approved and adopted and the merger is subsequently completed, Merger Sub will merge with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC.

Merger Consideration (page 171)

At the effective time of the merger, each outstanding share of Existing Benson Hill Common Stock, including common stock held by prior owners of Benson Hill Preferred Stock and Benson Hill Warrants (other than shares owned by Benson Hill as treasury stock and dissenting shares) will be cancelled and converted into the right to receive a pro rata portion (on a fully-diluted basis) of approximately 147,562,680 shares of New Benson Hill Common Stock (including 130,000,000 shares of New Benson Hill Common Stock, 8,781,340 $14 Earn Out Shares and 8,781,340 $16 Earn Out Shares) (including the portion of such shares of New Benson Hill Common Stock reserved for issuance upon the future exercise of any Net New Benson Hill Options and any New Benson Hill Warrants after the closing in accordance with the merger agreement). In addition to the foregoing, Earn Out Awards with a value equivalent to 2,037,320 shares of New Benson Hill Common Stock will be granted under the Incentive Plan to certain holders of Benson Hill Options. The number of Earn Out Shares and Earn Out Awards may be adjusted prior to the closing of the merger on a one-for-one basis pursuant to the terms and subject to the conditions set forth in the merger agreement such that the number of shares of New Benson Hill Common Stock issued as Earn Out Shares or being reserved for or subject to the Earn Out Awards granted shall not exceed 19,600,000 shares of New Benson Hill Common Stock in the aggregate. In addition, a portion of the New Benson Hill Common Stock shares reserved for issuance under the Incentive Plan shall be used to grant the Exercise Price Options.

Recommendation of the Benson Hill Board of Directors and Reasons for the Merger (page 161)

After consideration, the Benson Hill board of directors adopted resolutions determining that the merger agreement, the merger and the other transactions contemplated by the merger agreement were advisable and in the best interests of Benson Hill and its stockholders, authorizing and approving the merger agreement, the merger and the transactions contemplated thereby and directing that the merger agreement be submitted to the holders of Existing Benson Hill Common Stock and Benson Hill Preferred Stock for consideration. The Benson Hill board of directors recommends that Benson Hill stockholders adopt the merger agreement by submitting a written consent and thereby approve the merger and the other transactions contemplated by the merger agreement.

For a description of various factors considered by the Benson Hill board of directors in reaching its decision to adopt the merger agreement and approve the merger and the other transactions contemplated by the merger agreement, see the section titled “The Merger — Recommendation of the Benson Hill Board of Directors and Reasons for the Merger” beginning on page 161.

Recommendation of the STPC Board of Directors and Reasons for the Merger (page 163)

The STPC board of directors has unanimously determined that the merger, on the terms and conditions set forth in the merger agreement, is advisable and in the best interests of STPC and its stockholders and has directed that the proposals set forth in this proxy statement/prospectus be submitted to its stockholders for approval at the STPC Special Meeting on the date and at the time and place set forth in this proxy

statement/prospectus. The STPC board of directors unanimously recommends that STPC’s stockholders vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposals, “FOR” the NYSE Proposal, “FOR” the Incentive Plan Proposal and “FOR” the Adjournment Proposal (if necessary). See “The Merger — Recommendation of the STPC Board of Directors and Reasons for the Merger” beginning on page 163.

STPC Special Meeting of Stockholders (page 71)

The STPC Special Meeting will be held on            , 2021, at                  Eastern Time, via a virtual meeting. At the STPC Special Meeting, STPC stockholders will be asked to approve the Business Combination Proposal, the Charter Proposals, the NYSE Proposal, the Incentive Plan Proposal and the Adjournment Proposal (if necessary).

The STPC board of directors has fixed the close of business on            , 2021 (“STPC record date”) as the record date for determining the holders of STPC common stock entitled to receive notice of and to vote at the STPC Special Meeting. As of the STPC record date, there were      shares of Class A Common Stock and 10,062,500 shares of Class B Common Stock outstanding and entitled to vote at the STPC Special Meeting held by holders of record. Each share of STPC common stock entitles the holder to one (1) vote at the STPC Special Meeting on each proposal to be considered at the STPC Special Meeting. As of the STPC record date, the Sponsor and STPC’s directors and executive officers and their affiliates owned and were entitled to vote 10,062,500 shares of STPC common stock, representing approximately 20% of the shares of STPC common stock outstanding on that date. STPC currently expects that the Sponsor and its directors and officers will vote their shares in favor of the proposals set forth in this proxy statement/prospectus, and, pursuant to an agreement entered into in connection with STPC’s IPO, the Sponsor and STPC’s directors have agreed to do so. As of the STPC record date, Benson Hill did not beneficially hold any shares of STPC common stock.

A majority of the voting power of the issued and outstanding STPC common stock entitled to vote at the STPC Special Meeting must be present, online or represented by proxy, at the STPC Special Meeting to constitute a quorum and in order to conduct business at the STPC Special Meeting.

Approval of the Business Combination Proposal, the NYSE Proposal and the Incentive Plan Proposal require the affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present.

Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the then-outstanding shares of STPC common stock, voting together as a single class, and the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting separately as a single class. Approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class, regardless of whether a quorum is present. The STPC board of directors has already approved each of the proposals.

If STPC stockholders fail to approve the Business Combination Proposal or the NYSE Proposal or, unless otherwise waived by Benson Hill and STPC in accordance with the merger agreement, the Charter Proposals or the Incentive Plan Proposal, the merger will not occur. The Charter Proposals and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal and the NYSE Proposal. The Adjournment Proposal is not conditioned on the approval of any other proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the stockholders for a vote.

STPC’s Directors and Executive Officers Have Financial Interests in the Merger (page 166)

Certain of STPC’s executive officers and directors may have interests in the merger that may be different from, or in addition to, the interests of STPC’s stockholders. The members of the STPC board of directors were aware of and considered these interests, among other matters, when they approved the merger agreement and recommended that STPC stockholders approve the proposals required to effect the merger. See “The Merger — Interests of STPC Directors and Executive Officers in the Merger” beginning on page 166.

Treatment of Benson Hill Equity Awards (page 172)

As of the effective time, each Benson Hill Option, whether vested or unvested, and each Benson Hill Warrant, in each case, that is outstanding immediately prior to the effective time will, by virtue of the occurrence of the effective time and without any action on the part of Benson Hill, STPC or any holder of Benson Hill equity thereof, be assumed and converted into a New Benson Hill Option (an “Assumed Option”) or a New Benson Hill Warrant (an “Assumed Warrant”). Each Assumed Option will be converted into an option with respect to a number of shares of New Benson Hill Common Stock equal to the number of shares of Existing Benson Hill Common Stock subject to such Benson Hill Option immediately prior to the effective time multiplied by the exchange ratio set forth in the merger agreement (rounded down to the nearest whole share) and at an exercise price per share of New Benson Hill Common Stock equal to the exercise price per share of Existing Benson Hill Common Stock subject to such Benson Hill Option divided by the exchange ratio set forth in the merger agreement (rounded up to the nearest whole cent). Each Assumed Warrant will be converted into a warrant with respect to the number of shares of New Benson Hill Common Stock equal to the number of shares of Existing Benson Hill Common Stock subject to such Benson Hill Warrant immediately prior to the effective time multiplied by the exchange ratio set forth in the merger agreement (rounded down to the nearest whole share) and at an exercise price per share of New Benson Hill Common Stock equal to the exercise price per share of Existing Benson Hill Common Stock subject to such Benson Hill Warrant divided by the exchange ratio set forth in the merger agreement (rounded up to the nearest whole cent). A portion of the shares of New Benson Hill Common Stock comprising merger consideration will be reserved for issuance upon exercise of certain outstanding options and warrants to purchase capital stock of Benson Hill that remain outstanding after the merger.

Regulatory Approval Required for the Merger (page 168)

Completion of the merger is subject to approval under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”). STPC and Benson Hill agreed to use their reasonable best efforts to obtain all required regulatory approvals. Under the HSR Act, and related rules, the transactions may not be completed until notifications have been filed with and certain information has been furnished to the Antitrust Division of the Department of Justice (the “Antitrust Division”) and the Federal Trade Commission (the “FTC”) and all statutory waiting period requirements have been satisfied. STPC and Benson Hill filed Notification and Report Forms with the Antitrust Division and the FTC on May 21, 2021. The waiting period expired at 11:59 p.m. (ET) on June 21, 2021. The regulatory approval to which completion of the merger is subject is described in more detail in the section of this proxy statement/prospectus entitled “Regulatory Approval Required For The Merger” beginning on page 168.

Notwithstanding any Company Change in Recommendation or the making of any Acquisition Proposal, unless the merger agreement has been validly terminated, (A) in no event will Benson Hill or any of its subsidiaries enter into any letter of intent or contracts with respect to an Acquisition Proposal, (B) Benson Hill will otherwise remain subject to the terms of the merger agreement, including Benson Hill’s obligation to take all actions necessary to cause the written consent approving the merger agreement and the merger to be duly executed and delivered, and (C) Benson Hill will not release any third-party from, or waive, amend or modify any standstill or confidentiality provision with respect to an Acquisition Proposal involving the sale of more than 50% of the voting securities of Benson Hill or 50% or more the consolidated net revenue, net income or assets of Benson Hill and its subsidiaries.

From the date of the execution of the merger agreement until the earlier of the closing of the merger agreement or the termination of the merger agreement in accordance with its terms, STPC and Merger Sub shall not, and each of them shall cause their representatives not to on behalf of the STPC and Merger Sub, directly or indirectly: (i) accept, initiate, respond to, knowingly encourage, solicit, negotiate, provide information with respect to or discuss other offers with respect to any merger, capital stock exchange, asset acquisition, stock purchase, reorganization, recapitalization or similar business combination with any person other than the Company and its representatives (each, a “STPC Proposal”), (ii) issue or execute any contract, indication of interest, memorandum of understanding, letter of intent, or any other similar agreement with respect to a STPC Proposal, (iii) commence, continue or otherwise participate in any discussions or negotiations regarding, or cooperate in any way in connection with a STPC Proposal, or (iv) commence, continue or renew any due diligence investigation regarding a STPC Proposal.

Notwithstanding any Company Change in Recommendation or the making of any Acquisition Proposal, unless the merger agreement has been validly terminated, (A) in no event shall STPC or Merger Sub execute or enter into any letter of intent or contracts relating to any STPC Proposal or terminate the merger agreement in connection therewith, and (B) STPC and Merger Sub shall otherwise remain subject to the terms of the merger agreement.

Termination (page 185)

The merger agreement may be terminated by written consent of each of STPC and Benson Hill, or as set forth in this section.

5

Mutual termination rights.

The merger agreement may be terminated by either STPC or Benson Hill:

•

by written consent of Benson Hill and STPC;

•

by written notice from either Benson Hill or STPC to the other if the STPC Special Meeting has been held (including any adjournment or postponement thereof), has concluded, STPC’s stockholders have duly voted, and the approval of the merger agreement and the transactions contemplated thereby are not obtained;

•

by written notice from either Benson Hill or STPC to the other if the closing has not occurred on or prior to February 28, 2022 (subject to a two-month extension as a result in delays in obtaining necessary regulatory or stock exchange approvals) for any reason other than delay and/or nonperformance of the party seeking such termination;

•

by written notice from either Benson Hill or STPC to the other if a governmental authority has issued an order or taken an action permanently enjoining, restraining or otherwise prohibiting the transactions contemplated by the merger agreement or any ancillary document and such order has become final and nonappealable; or

•

by either STPC or the Company if the STPC Special Meeting has been held (including any adjournment or postponement thereof), has concluded, STPC’s stockholders have duly voted, and the STPC Stockholder Approval was not obtained.

Benson Hill termination rights.

The merger agreement may be terminated by Benson Hill if:

•

by written notice to STPC from Benson Hill, if Benson Hill is not in breach of the closing conditions applicable to it in the merger agreement and if the representations and warranties of either of STPC or Merger Sub are not true and correct or if either of STPC or Merger Sub has failed to perform any covenant or agreement to be performed by STPC or Merger Sub, as applicable, in such a way that the conditions to closing in the merger agreement would not be satisfied and such breach or breaches are not or cannot be cured before the earlier of (i) thirty (30) days after written notice of any such breach is delivered to STPC and (ii) February 28, 2022 (subject to a two-month extension as a result in delays in obtaining necessary regulatory or stock exchange approvals).

Other Agreements (page 188)

STPC Letter Agreement

Pursuant to the terms of a letter agreement (the “Letter Agreement”) entered into with STPC, the Sponsor and STPC’s officers and directors have agreed to vote shares representing approximately 20% of

6

the aggregate voting power of the STPC common stock in favor of the Business Combination Proposal. The Sponsor, STPC’s officers and directors and their permitted transferees own at least 20% of its outstanding common stock entitled to vote thereon. The quorum and voting thresholds at the STPC Special Meeting and the Letter Agreement may make it more likely that STPC will consummate the merger. In addition, pursuant to the terms of the Letter Agreement, the Sponsor and STPC’s officers and directors have agreed to waive their redemption rights with respect to any Founder Shares and any shares of Class A Common Stock held by them in connection with the completion of a business combination. See “Other Agreements — STPC Letter Agreement” beginning on page 188.

Subscription Agreements

In connection with the execution of the merger agreement, each of STPC and certain third-party investors (the “PIPE Investors”) entered into subscription agreements (the “PIPE Agreements”) pursuant to which the PIPE Investors have respectively subscribed for 22.5 million shares of Class A Common Stock of STPC to be issued immediately following the effective time of the merger. The obligations to consummate the subscriptions contemplated by the PIPE Agreements are conditioned upon, among other things, customary closing conditions and the consummation of the merger as set forth in the PIPE Agreements. See “Other Agreements — Subscription Agreements” beginning on page 188.

Support Agreements

Concurrent with the execution of the merger agreement, certain holders representing approximately 67% of the outstanding shares of Existing Benson Hill Common Stock and Benson Hill Preferred Stock (determined on an as-converted basis) (“supporting holders”) entered into support agreements (the “support agreements”) with STPC. Under the support agreements, the supporting holders agreed, among other things, to execute and deliver a written consent adopting and approving the merger agreement and the merger within two (2) business days after the date on which this proxy statement/prospectus is declared effective by the SEC. As of the execution date of the merger agreement, the current directors and executive officers of Benson Hill held approximately 2.53% of the outstanding shares of Existing Benson Hill Common Stock and Benson Hill Preferred Stock (determined on an as-converted basis) and entered into support agreements with respect to such shares. See “Other Agreements — Support Agreements” beginning on page 188.

Investor Rights Agreement

In connection with the consummation of the merger, New Benson Hill will enter into an investor rights agreement (the “IRA”) with STPC, the holders of Founder Shares (including the Sponsor) and certain equityholders of Benson Hill, which will provide for customary “demand” and “piggyback” registration rights for certain stockholders. The IRA will also provide the Sponsor with certain director designation rights for three years following the closing. The IRA will become effective upon the consummation of the merger. See “Other Agreements — Investor Rights Agreement” beginning on page 189.

Sponsor Support Agreement

Concurrent with the execution of the merger agreement, STPC entered into a support agreement with the Sponsor and certain other holders of Founder Shares (the “Class B Holders”) pursuant to which (i) the Class B Holders agreed to vote any shares of STPC common stock owned by them in favor of the transactions contemplated by the merger agreement, (ii) the Sponsor agreed to convert 1,996,500 shares of its Class B Common Stock into New Benson Hill Common Stock subject to substantially the same terms and restrictions as apply to Earn Out Shares (but which are not held in escrow) (the “Sponsor Earn Out Shares”) and (iii) on behalf of itself and the other Class B Holders, Sponsor has agreed to waive certain of their anti-dilution and conversion rights. See “Other Agreements — Sponsor Support Agreement” beginning on page 189.

Lock-Up Agreements

In connection with the execution of the merger agreement, the parties agreed that members of Benson Hill management and certain holders of Existing Benson Hill Common Stock and Benson Hill Preferred Stock (or any securities convertible into Existing Benson Hill Common Stock or Benson Hill Preferred Stock)

7

not party to the IRA (the “Lock-Up Parties”) enter into a lock-up agreement (the “Lock-Up Agreement”) with STPC or any successor entity thereto at the closing, pursuant to which the Lock-Up Parties will not be able to transfer shares beneficially owned or otherwise held by them for a period of six (6) months, subject to certain customary exceptions. See “Other Agreements — Lock-Up Agreements” beginning on page 189.

Earn Out Shares Escrow Agreement

In connection with the consummation of the merger, New Benson Hill will enter into an earnout escrow agreement (the “Escrow Agreement”) with the Holder Representative and the escrow agent, which will provide that the Earn Out Shares be placed in escrow until the time that such shares have vested in the manner set forth in the merger agreement. If the thirty six- (36-) month period following the closing of the merger (“the Earn Out Period”) expires and the Earn Out Shares have not vested, such shares shall be released to New Benson Hill for cancellation. See “Other Agreements — Earn Out Shares Escrow Agreement” beginning on page 189.

Public Trading Markets (page 170)

The Class A Common Stock is listed on the NYSE under the symbol “STPC.” Following the merger, New Benson Hill Common Stock (including common stock issuable in the merger) and public warrants will be listed on the NYSE under the symbols “BHIL” and “BHIL WS,” respectively.

Comparison of Stockholders’ Rights (page 215)

Following the merger, the rights of public holders who become New Benson Hill stockholders in the merger will no longer be governed by STPC’s Existing Charter and bylaws and instead will be governed by New Benson Hill’s Proposed Charter and amended and restated bylaws. See “Comparison of Stockholders’ Rights” beginning on page 215.

Risk Factors (page 26)

You should consider all the information contained in this proxy statement/prospectus in deciding how to vote for the proposals presented in the proxy statement/prospectus. In particular, you should carefully read and consider the factors described under “Risk Factors Summary” below, and “Risk Factors” beginning on page 26.

Risk Factors Summary

The transactions described in this proxy statement/prospectus involve various risks, and you should carefully read and consider the factors discussed under “Risk Factors.” The following is a summary of some of these risks.

Risks Relating to Benson Hill’s Business and Industry

•

We have a limited operating history, which makes it difficult to evaluate our current business and prospects and may increase the risk of investment.

•

We have a history of net losses and we may not achieve or maintain profitability.

•

We face significant competition and many of our competitors have substantially greater financial, technical and other resources than we do.

•

Our business activities are currently conducted at a limited number of locations, which makes us susceptible to damage or business disruptions caused by natural disasters or acts of vandalism.

•

To compete effectively, we must introduce new products that achieve market acceptance.

•

The overall agricultural industry is susceptible to commodity price changes and we are exposed to market risks from changes in commodity prices.

•

Adverse weather conditions, natural disasters, crop disease, pests and other natural conditions can impose significant costs and losses on our business.

8

•

The regulatory environment in the United States for our current and future products is uncertain and evolving.

•

The regulatory environment outside the United States varies greatly from jurisdiction to jurisdiction and there is less certainty how our products will be regulated.

•

Government policies and regulations, particularly those affecting the agricultural sector and related industries, could adversely affect our operations and profitability.

•

Patents and patent applications involve highly complex legal and factual questions, which, if determined adversely to us, could negatively impact our competitive position.

•

We will not seek to protect our intellectual property rights in all jurisdictions throughout the world and we may not be able to adequately enforce our intellectual property rights even in the jurisdictions where we seek protection.

Risks Relating to the Merger

•

STPC stockholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

•

The market price of shares of New Benson Hill Common Stock after the merger may be affected by factors different from those currently affecting the prices of shares of Class A Common Stock.

•

STPC has not obtained an opinion from an independent investment banking firm, and consequently, there is no assurance from an independent source that the merger consideration is fair to its stockholders from a financial point of view.

•

The consummation of the merger is subject to a number of conditions and if those conditions are not satisfied or waived, the merger agreement may be terminated in accordance with its terms and the merger may not be completed.

•

The merger will result in changes to the board of directors of New Benson Hill that may affect the strategy of New Benson Hill.

•

Because of STPC’s limited resources and the significant competition for business combination opportunities, if the merger is not completed, it may be more difficult for it to complete an initial business combination. If STPC is unable to complete an initial business combination, its public stockholders may receive only approximately $10.00 per share on its redemption of its shares of Class A Common Stock, or less than such amount in certain circumstances, based on the balance of its Trust Account (as of June 30, 2021), and its warrants will expire worthless.

•

STPC does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for STPC to consummate an initial business combination with which a substantial majority of STPC’s stockholders do not agree.

•

STPC stockholders may be held liable for claims by third parties against STPC to the extent of distributions received by them upon redemption of their shares.

•

STPC’s ability to successfully effect the merger and the other transactions contemplated by the merger agreement and New Benson Hill’s ability to successfully operate the business thereafter will be largely dependent upon the efforts of certain key personnel of Benson Hill, all of whom STPC expects to stay with the combined company following the consummation of the merger. Any loss of such key personnel could negatively impact the operations and financial results of the combined business.

Additional Risks Relating to Ownership of New Benson Hill Common Stock Following the Merger

•

The NYSE may delist New Benson Hill’s securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject New Benson Hill to additional trading restrictions.

•

If New Benson Hill is unable to remediate the material weaknesses in its internal control over financial reporting, or if New Benson Hill identifies additional material weaknesses in the future or

9

otherwise fails to maintain an effective system of internal control over financial reporting, this may result in material misstatements of Benson Hill’s consolidated financial statements or failure to meet its periodic reporting obligations.

•

New Benson Hill’s stock price may change significantly following the merger and you could lose all or part of your investment as a result.

•

Because there are no current plans to pay cash dividends on New Benson Hill Common Stock for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

•

Future sales, or the perception of future sales, by New Benson Hill or its stockholders in the public market following the merger could cause the market price for New Benson Hill Common Stock to decline.

•

Certain of New Benson Hill’s stockholders, including the Sponsor, may engage in business activities which compete with New Benson Hill or otherwise conflict with New Benson Hill’s interests.

Risks Relating to Redemption

•

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

•

If STPC public stockholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their shares of Class A Common Stock for a pro rata portion of the funds held in the Trust Account.

Summary of the Transactions

Set forth below is a summary of transactions that are contemplated to occur in connection with following the merger.

Conversion of Equity Interests

As of the effective time, each Benson Hill Option, whether vested or unvested, and each Benson Hill Warrant, in each case, that is outstanding immediately prior to the effective time will, by virtue of the occurrence of the effective time and without any action on the part of Benson Hill, STPC or any holder of Benson Hill equity thereof, be assumed and converted into an Assumed Option or an Assumed Warrant. Each Assumed Option will be converted into a number of shares of New Benson Hill Common Stock equal to the number of shares of Existing Benson Hill Common Stock subject to such Benson Hill Option immediately prior to the effective time multiplied by the exchange ratio set forth in the merger agreement (rounded down to the nearest whole share) and at an exercise price per share of STPC common stock equal to the exercise price per share of Existing Benson Hill Common Stock subject to such Benson Hill Option divided by the exchange ratio set forth in the merger agreement (rounded up to the nearest whole cent). Each Assumed Warrant will be converted into a warrant with respect to the number of shares of New Benson Hill Common Stock equal to the number of shares of Existing Benson Hill Common Stock subject to such Benson Hill Warrant immediately prior to the effective time multiplied by the exchange ratio set forth in the merger agreement (rounded down to the nearest whole share) and at an exercise price per share of STPC common stock equal to the exercise price per share of Existing Benson Hill Common Stock subject to such Benson Hill Warrant divided by the exchange ratio set forth in the merger agreement (rounded up to the nearest whole cent). A portion of the shares of New Benson Hill Common Stock comprising merger consideration will be reserved for issuance upon exercise of certain outstanding options and warrants to purchase capital stock of Benson Hill that remain outstanding after the merger.

PIPE Investment

Contemporaneously with the execution and delivery of the merger agreement, STPC and the PIPE Investors entered into the PIPE Agreements pursuant to which the PIPE Investors have committed (the “PIPE Investment”), on the terms and subject to the conditions of the PIPE Agreements, to subscribe for and purchase 22.5 million shares of Class A Common Stock of STPC for consideration in an aggregate amount of $225.0 million (such amount the “PIPE Investment Amount”).

As of the date of this proxy statement/prospectus, there are      shares of STPC common stock issued and outstanding, including 10,062,500 shares of Class B Common Stock, which will be converted into shares of Class A Common Stock on a one-for-one basis. As of the date of this proxy statement/prospectus, there are an aggregate of 10,062,500 public warrants and 6,553,454 Private Placement Warrants outstanding. Each whole warrant entitles the holder thereof to purchase one (1) share of Class A Common Stock. Therefore, as of the date of this proxy statement/prospectus (without giving effect to the merger and assuming no redemptions), assuming that each outstanding warrant is exercised and one (1) share of Class A Common Stock is issued as a result of such exercise, the STPC fully-diluted stock capital would be      shares of common stock.

The following table illustrates varying beneficial ownership levels in New Benson Hill immediately following consummation of the merger and the closing of the PIPE Investment, assuming the levels of redemptions by the public stockholders of STPC indicated:

​	Share Ownership in New Benson Hill (1)
​	No Redemption (2)				Maximum Possible Redemption (3)
​	Number of Shares		Percentage of Outstanding Shares		Number of Shares		Percentage of Outstanding Shares
Former equityholders of Benson Hill (1)	​	136,841,207	​	65.3%	​	136,841,207	​	80.8%
STPC’s public stockholders	​	40,250,000	​	19.2%	​	—	​	—
Holders of STPC’s Class B Common Stock (1)	​	10,062,500	​	4.8%	​	10,062,500	​	5.9%
PIPE Investors	​	22,500,000	​	10.7%	​	22,500,000	​	13.3%

(1)

Figures and percentages include the 17.6 million Earn Out Shares and the 2.0 million Sponsor Earn Out Shares but exclude the 13.0 million shares of New Benson Hill Common Stock reserved for issuance under the Incentive Plan. See “Proposal No. 7  —  The Incentive Plan Proposal” for additional information. See “Basis of Presentation and Glossary” for additional information with respect to assumptions underlying New Benson Hill share calculations and ownership percentages.

(2)

This scenario assumes that no shares of Class A Common Stock are redeemed.

(3)

This scenario assumes that 40,250,000 shares of Class A Common Stock are redeemed for an aggregate payment of approximately $402,629,000 from the Trust Account, which is the maximum amount of redemptions that would satisfy STPC having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) remaining after the closing.

SUMMARY UNAUDITED PRO FORMA
COMBINED FINANCIAL INFORMATION

The summary unaudited pro forma combined financial information gives effect to the merger and other transactions contemplated by the merger agreement, as more fully described below. The merger will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, STPC will be treated as the “acquired” company for accounting purposes and the merger will be treated as the equivalent of Benson Hill issuing stock for the net assets of STPC, accompanied by a recapitalization. The net assets of STPC will be stated at historical cost, with no goodwill or other intangible assets recorded.

The summary unaudited pro forma combined balance sheet of the combined company as of June 30, 2021 and the summary unaudited pro forma combined statements of operations of the combined company for the six months ended June 30, 2021 and the year ended December 31, 2020 present the combination of the financial information of STPC and Benson Hill after giving effect to the following transactions:

•

the reverse recapitalization between Benson Hill and STPC pursuant to the merger,

•

the consummation of STPC’s IPO which occurred on January 8, 2021,

•

the conversion of Benson Hill preferred stock warrants into redeemable convertible preferred stock and subsequent conversion of all redeemable convertible preferred stock into Existing Benson Hill Common Stock (the “Benson Hill Preferred Conversion”),

•

the payoff by Benson Hill of its outstanding term debt and notes payable (the “Debt Payoff”), and

•

the issuance of an aggregate of 22.5 million shares of Class A Common Stock of STPC at a price of $10.00 per share pursuant to the PIPE Investment.

Collectively these transactions are referred to as the “Transaction Adjustments”. The summary unaudited pro forma combined statements of operations for the six months ended June 30, 2021 and the year ended December 31, 2020 give effect to the Transaction Adjustments as if they had occurred on January 1, 2020. The unaudited pro forma condensed combined balance sheet as of June 30, 2021 gives effect to the Transaction Adjustments as if they had occurred on June 30, 2021.

The unaudited pro forma combined financial information has been prepared after giving effect to the Transaction Adjustments, assuming two alternative levels of redemption of shares of STPC Class A Common Stock into cash:

•

Assuming No Redemptions: This presentation assumes that no STPC stockholders exercise redemption rights with respect to their shares of Class A Common Stock.

•

Assuming Maximum Redemptions: This scenario assumes that 40,250,000 shares of STPC’s Class A Common Stock are redeemed pursuant to their redemption rights at a redemption price of approximately $10.00 per share. The maximum redemption amount is derived to ensure a minimum consolidated cash balance of $225 million. This minimum cash balance is calculated before giving effect to payment of estimated transaction expenses of $49.7 million. This scenario includes all adjustments contained in the above scenario but presents additional adjustments to reflect the effect of the maximum redemptions.

The historical financial information has been adjusted to give pro forma effect to certain transaction adjustments to provide relevant information necessary for an accurate understanding of the combined company upon consummation of the merger and the PIPE Investment.

The historical financial information of STPC was derived from the unaudited condensed consolidated financial statements of STPC as of and for the six months ended June 30, 2021 and the audited financial statements of STPC as of December 31, 2020 and for the period from October 8, 2020 (inception) through December 31, 2020, which are included elsewhere in this proxy statement/prospectus. The historical financial information of Benson Hill was derived from the unaudited condensed consolidated financial statements of Benson Hill as of and for the six months ended June 30, 2021 and the audited consolidated financial statements of Benson Hill as of and for the year ended December 31, 2020, which are included elsewhere in this proxy statement/prospectus.

18

The summary pro forma information has been derived from, and should be read in conjunction with, the unaudited pro forma combined financial information of the combined company appearing elsewhere in this proxy statement/prospectus and the accompanying notes. The unaudited pro forma combined financial information is based upon, and should be read in conjunction with, the historical consolidated financial statements of Benson Hill and STPC and related notes included in this proxy statement/prospectus. The summary of unaudited pro forma combined financial information is for illustrative purposes only. The financial results may have been different had the companies actually been combined as of January 1, 2020. You should not rely on the unaudited pro forma combined financial information as being indicative of the historical results that would have been achieved had the companies actually been combined as of January 1, 2020 or the future results that the combined company will experience. Benson Hill and STPC have not had any historical relationship prior to the merger. Accordingly, no pro forma adjustments were required to eliminate activities between the companies.

UNAUDITED HISTORICAL COMPARATIVE AND PRO FORMA
COMBINED PER SHARE INFORMATION OF STPC AND BENSON HILL

The following table sets forth the unaudited historical comparative share information for Benson Hill and STPC on a stand-alone basis and the unaudited pro forma combined share information for the six months ended June 30, 2021 and the year ended December 31, 2020, after giving effect to the merger and the PIPE Investment, assuming two alternative levels of redemption of shares of STPC Class A Common Stock into cash:

•

Assuming No Redemptions: This presentation assumes that no STPC stockholders exercise redemption rights with respect to their shares of Class A Common Stock.

•

Assuming Maximum Redemptions: This scenario assumes that 40,250,000 shares of STPC’s Class A Common Stock are redeemed pursuant to their redemption rights at a redemption price of approximately $10.00 per share. The maximum redemption amount is derived to ensure a minimum consolidated cash balance of $225 million. This minimum cash balance is calculated before giving effect to payment of estimated transaction expenses of $49.7 million. This scenario includes all adjustments contained in above scenario but presents additional adjustments to reflect the effect of the maximum redemptions.

You should read the information in the following table in conjunction with the summary historical financial information included elsewhere in this proxy statement/prospectus, and the historical financial statements of Benson Hill and STPC and related notes that are included elsewhere in this proxy statement/prospectus. The unaudited pro forma combined share information is derived from, and should be read in conjunction with, the unaudited pro forma combined financial statements and related notes included elsewhere in this proxy statement/prospectus.

The unaudited pro forma combined share information below does not purport to represent what the actual results of operations or the earnings per share would have been had the companies been combined during the periods presented, nor to project STPC’s results of operations or earnings per share for any future date or period. The unaudited pro forma combined stockholders’ equity per share information below does not purport to represent what the value of Benson Hill and STPC would have been had the companies been combined during the periods presented.

RISK FACTORS

In addition to the other information contained in this proxy statement/prospectus, including the matters addressed under the heading “Forward-Looking Statements,” you should carefully consider the following risk factors in deciding how to vote on the proposals presented in this proxy statement/prospectus. Although we have organized risks generally according to these categories in the discussion below, many of the risks may have ramifications in more than one category. These categories, therefore, should be viewed as a starting point for understanding the significant risks facing us and not as a limitation on the potential impact of the matters discussed. References in this section to “we,” “our,” or “us” generally refer to Benson Hill, unless otherwise specified.

Risks Relating to Benson Hill’s Business and Industry

Unless otherwise indicated or the context otherwise requires, references in this section to “we,” “us,” “our” and other similar terms refer to Benson Hill and its consolidated subsidiaries prior to the merger and to New Benson Hill and its consolidated subsidiaries after giving effect to the merger.

Risks Relating to Our Business and Operations

We have a limited operating history, which makes it difficult to evaluate our current business and prospects and may increase the risk of investment.

We are an early-stage food-technology company with a limited operating history that to date has been focused primarily on research and development (“R&D”), software development, conducting field trials, pursuing initial commercialization efforts and building our management team. Investment in food technology development is a highly speculative endeavor. It entails substantial upfront R&D investment and there is significant risk that we will not be able to edit the genes in a particular plant to express a desired trait, or, once edited, we will not be able to replicate that trait across entire crops in order to commercialize the product candidate. Moreover, the regulatory pathway for our product candidates can be uncertain and could add significant additional cost and time to development.

Our limited operating history may make it difficult to evaluate our current business and our prospects. We have encountered, and will continue to encounter, risks and difficulties frequently experienced by growing companies in rapidly developing and changing industries, including challenges in forecasting accuracy, determining appropriate investments of our limited resources, gaining market acceptance of the products made using our gene-editing and speed breeding platform, crop prototyping process, managing a complex regulatory landscape and developing new product candidates. We may also face challenges in scaling our supply chain in a cost-effective manner, as we will rely on contracting with seed production companies, seed distributors, farmers, crushers, millers, refiners, food companies and retailers, and logistics and transportation providers, in order to get our products to market. In addition, there is limited crushing and processing capacity for our soybean-based products which could restrict our ability to scale production of these products. Our current operating model may require changes for us to scale our operations efficiently. We may not be able to fully implement or execute on our business strategy or realize, in whole or in part within our expected time frames, the anticipated benefits of our growth strategies. You should consider our business and prospects considering the risks and difficulties we face as an early-stage company focused on developing products in the field of food technology.

We have a history of net losses and we may not achieve or maintain profitability.

Our net losses for the six months ended June 30, 2021 were $49.8 million and for the years ended December 31 were $67.2 million for 2020, $43.9 million for 2019 and $18.1 million for 2018. As of June 30, 2021, we had an accumulated deficit of $204.1 million. We will need to generate significant revenues to achieve profitability, and we may not be able to achieve and maintain profitability in the near future or at all, which may depress our stock price. Through June 30, 2021, we have derived substantially all of our revenues through the acquisitions of existing businesses. Our future success will depend, in part, on our ability to grow revenue associated with closed loop production, production partnerships and the licensing of our intellectual property and our ability to market and sell additional products from our pipeline of product candidates.

26

The net losses we incur may fluctuate significantly from year-to-year and quarter-to-quarter, such that a period-to-period comparison of our results of operations may not be a good indication of our future performance.

We cannot assure you that we will generate increases in our revenues, successfully commercialize products or generate revenue from licensing or attain a level of profitable operations. Based on our history of losses, we do not expect that we will be able to fund our longer-term capital and liquidity needs through our cash balances and operating cash flow alone. To fund our longer-term capital and liquidity needs, we expect we will need to secure additional capital. Our business plan and financing needs are subject to change depending on, among other things, the success of our efforts to grow revenue and our efforts to continue to effectively manage expenses.

We face significant competition and many of our competitors have substantially greater financial, technical and other resources than we do.

The market for plant-based products is highly competitive, and we face significant direct and indirect competition in several aspects of our business. Mergers and acquisitions in the plant science, specialty food ingredient and agricultural biotechnology, and seed industries may result in even more resources being concentrated among a smaller number of our competitors.

Most of these competitors have substantially greater financial, technical, marketing, sales, distribution, supply chain infrastructure, and other resources than we do, such as larger R&D staff, more experienced marketing, manufacturing, and supply chain organizations and more well-established sales forces. As a result, we may be unable to compete successfully against our current or future competitors, which may result in price reductions, reduced margins and the inability to achieve market acceptance for our products. We expect to continue to face significant competition in the markets in which we intend to commercialize our products.

Many of our competitors engage in ongoing R&D, and technological developments by our competitors could render our products less competitive or obsolete, resulting in reduced sales compared to our expectations. Our ability to compete effectively and to achieve commercial success depends, in part, on our ability to: control manufacturing and marketing costs; effectively price and market our products; successfully develop an effective marketing program and an efficient supply chain; develop new products with properties attractive to customers; and commercialize our products quickly without incurring major regulatory costs. We may not be successful in achieving these factors and any such failure may adversely affect our business, results of operations and financial condition.

From time to time, certain companies that are potential competitors of ours may seek new traits or trait development technologies and may seek to license our technology. We have, in the past, entered such licensing arrangements and may continue to enter such arrangements in the future. Some of these companies may have significantly greater financial resources and may even compete with our business. In such circumstances, competitors could use our technologies to develop their own products that would compete with our products.

We also anticipate increased competition in the future as new companies enter the market and new technologies become available, particularly in the area of gene editing. Our technology may be rendered obsolete or uneconomical by technological advances or entirely different approaches developed by one or more of our competitors that are more effective or that enable them to develop and commercialize products more quickly or with lower expense than we are able to. If for any reason our technology becomes obsolete or uneconomical relative to our competitors’ technologies, this would prevent or limit our ability to generate revenues from the commercialization of our products.

Our business activities are currently conducted at a limited number of locations, which makes us susceptible to damage or business disruptions caused by natural disasters or acts of vandalism.

Our current headquarters and research and development facilities, which include an office, labs, greenhouses, field testing acreage, and a demonstration test kitchen, are primarily located in St. Louis, Missouri. Our seed production, field-testing and production and research take place primarily in the United States, with concentration in certain geographic regions. Third party warehousing for seed storage, and

27

our limited number of processing partners (e.g., storage, transportation, crushers and refiners) are all currently located in the United States. We take precautions to safeguard our facilities, including insurance and health and safety protocols. Particularly in the case of insurance, our insurance may not cover certain losses, or our losses may exceed our coverage limits. A natural disaster, such as a hurricane, drought, fire, flood, tornado, earthquake, or other intentional or negligent acts, including acts of vandalism, could damage or destroy our equipment, inventory, development projects, field trials or data, and cause us to incur significant additional expenses to repair or replace the damaged physical facilities, which in the case of seed production may be the result of years of development work that is not easily or quickly reproduced, and increase the development schedule for our pipeline of product candidates.

To compete effectively, we must introduce new products that achieve market acceptance.

In order to remain competitive and increase revenue, we must introduce new products from our pipeline of product candidates. If we fail to anticipate or respond to technological developments, market requirements, or consumer preferences, or if we are significantly delayed in developing and introducing products, our revenues will not increase.

Development of successful agricultural products using gene-editing technologies requires significant levels of investment in R&D, including laboratory, greenhouse and field testing, to demonstrate product effectiveness and can take several years or more. We incurred R&D expenses of $15.9 million in the six months ended June 30, 2021, $29.5 million in the year ended December 31, 2020, $24.8 million in the year ended December 31, 2019, and $13.4 million in the year ended December 31, 2018. We must commit significant resources and may incur obligations (such as royalty obligations or milestone fees) to develop new products before knowing whether our investments will result in products the market will accept and without knowing the levels of revenue, if any, that may be derived from these products.

Development of new or improved agricultural products involve risks of failure inherent in the development of products based on innovative and complex technologies. These risks include the possibility that:

•

our products may not perform as expected in the field;

•

our products may not receive necessary regulatory permits and governmental clearances in the markets in which we intend to sell them;

•

consumer preferences, which are unpredictable and can vary greatly, may change quickly, making our products no longer desirable;

•

our competitors may develop new products that taste better or have other more appealing characteristics than our products;

•

our products may be viewed as too expensive by our customers as compared to competitive products;

•

our products may be difficult to produce on a large scale or may not be economical to grow;

•

intellectual property and other proprietary rights of third parties may prevent us or our collaborators from marketing and selling our products;

•

we may be unable to patent or otherwise obtain intellectual property protection for our discoveries in the necessary jurisdictions;

•

we or our collaborators may be unable to fully develop or commercialize products in a timely manner or at all; and

•

third parties may develop superior or equivalent products.

Accordingly, if we experience any significant delays in the development or introduction of new products or if our new products do not achieve market acceptance, our business, operating results and financial condition would be adversely affected.

Any collaboration arrangements that we may enter in the future may not be successful, which could adversely affect our ability to develop and commercialize our product candidates.

We may seek collaboration arrangements with third parties for the development or commercialization of our products. We will face, to the extent that we decide to enter collaboration arrangements, significant

28

competition in seeking appropriate partners. Moreover, collaboration arrangements are complex and time-consuming to negotiate, document, implement and maintain. We may not be successful in our efforts to establish and implement collaboration or other alternative arrangements should we so chose to enter such arrangements. The terms of any collaborations or other arrangements that we may establish may not be favorable to us.

If our early testing of pipeline products is unsuccessful, we may be unable to complete the development of product candidates on a timely basis or at all.

We rely on early testing and research, including greenhouse activities and field trials, to demonstrate the efficacy of product candidates that we develop and evaluate. Field trials allow us to test product candidates in the field as well as to increase seed production, and to measure performance across multiple geographies and conditions. Successful completion of early testing is critical to the success of our product development efforts. If our ongoing or future testing is unsuccessful or produces inconsistent results or unanticipated adverse effects on the agronomic performance of our crops, or if the testing does not produce reliable data, our product development efforts could be delayed, subject to additional regulatory review or abandoned entirely. In addition, in order to support our commercialization efforts, it is necessary to collect data across multiple growing seasons and from different geographies. Even in cases where initial field trials are successful, we cannot be certain that additional field trials conducted on a greater number of acres or in different geographies will also be successful. Many factors that are beyond our control may adversely affect the success of these field trials, including unique geographic conditions, weather and climatic variations, disease or pests, or acts of protest or vandalism. Field trials, which may take up to two to three years, are costly, and any field trial failures that we may experience may not be covered by insurance and, therefore, could result in increased costs, which may negatively impact our business and results of operations.

The successful commercialization of our products depends on our ability to produce high-quality products cost-effectively on a large scale and to accurately forecast demand for our products, and we may be unable to do so.

The production of commercial-scale quantities of seeds and products requires the multiplication of the plants or seeds through a succession of plantings and seed harvests. The cost-effective production of high-quality, high-volume quantities of any product candidates we successfully develop depends on our ability to scale our production processes to produce plants and seeds in enough quantity to meet demand. For example, food ingredients such as soybean oil and soy protein concentrate will require optimized production and commercialization of the underlying plant and seed harvests. We cannot assure that our existing or future seed production techniques will enable us to meet our large-scale production goals cost-effectively for the products in our pipeline. Even if we are successful in developing ways to minimize yield drag and enhance quality, we may not be able to do so cost- effectively or on a timely basis, which could adversely affect our ability to achieve profitability. If we are unable to maintain or enhance the quality of our plants and seeds as we increase our production capacity, including through the expected use of third parties, we may experience reductions in customer or farmer demand, higher costs and increased inventory write-offs.

In addition, because of the length of time it takes to produce commercial quantities of marketable seeds, we will need to make seed production decisions well in advance of product sales. Our ability to accurately forecast supply can be adversely affected by several factors outside of our control, including changes in market conditions, environmental factors, such as pests and diseases, and adverse weather conditions. A shortfall in the supply of our products may reduce product revenue, damage our reputation in the market and adversely affect relationships. Any product surplus we have on hand may negatively impact cash flows, reduce the quality of our inventory and ultimately result in write-offs of inventory.

Additionally, we will take financial risk in our inventory given that we will have to keep the inventory at its net realizable value on our balance sheet. Fluctuations in the spot price of our crops in inventory could have negative impacts on our consolidated financial statements. Any failure on our part to produce enough inventory, or overproduction of a product, could harm our business, results of operations and financial condition. In addition, our customers may cancel orders, request a decrease in quantity, or make returns, which may lead to a surplus of our products.

29

While we estimate that the potential size of our target markets for our products is significant, that estimate has not been independently verified and is based on certain assumptions that may not prove to be accurate. Our ability to accurately forecast demand is dependent on the timing of customer decisions, qualification cycles, and other factors outside of our control. As a result, these estimates could differ materially from actual market sizes, which could result in decreased demand for our products and therefore adversely impact our future business prospects, results of operation and financial condition.

If we fail to manage our future growth effectively, our business could be materially adversely affected.

We have grown rapidly since inception and anticipate further growth. For example, our revenues increased from $4.3 million in 2018 to $114.3 million in 2020. Our full-time employee count as of December 31, 2020 has grown by 400% since December 31, 2018. This growth has placed significant demands on our management, financial, operational, technological and other resources. The anticipated growth and expansion of our business and our product offerings will continue to place significant demands on our management and operations teams and require significant additional resources to meet our needs, which may not be available in a cost-effective manner, or at all. If we do not effectively manage our growth, we may not be able to execute on our business plan, respond to competitive pressures, take advantage of market opportunities, satisfy customer requirements or maintain high-quality product offerings, any of which could harm our business, brand, results of operations and financial condition.

The successful commercialization of our products may face challenges from public perceptions of gene-edited products and ethical, legal, environmental, health and social concerns.

The successful commercialization of our product candidates depends, in part, on public acceptance of gene-edited agricultural products.

Consumers may not understand the nature of our technologies or the scientific distinction between our non-transgenic gene-edited products and transgenic products of competitors. Non-transgenic gene-edited products are final products that do not contain any genes foreign to the plant species. As a result, they may transfer negative perceptions and attitudes regarding transgenic products to our products and product candidates. A lack of understanding of our technologies may also make consumers more susceptible to the influence of negative information provided by opponents of biotechnology. Some opponents of biotechnology actively seek to raise public concern about gene editing, whether transgenic or non-transgenic, by claiming that plant products developed using biotechnology are unsafe for consumption or their use, pose a risk of damage to the environment, or creates legal, social and ethical dilemmas. The commercial success of our products and product candidates may be adversely affected by such claims, even if unsubstantiated. In addition, opponents of biotechnology have vandalized the fields of farmers planting biotech seeds and facilities used by biotechnology companies. Any such acts of vandalism targeting the fields of our farmers, our field-testing sites or our research, production or other facilities, could adversely affect our sales and our costs.

Negative public perceptions about gene editing can also affect the regulatory environment in the jurisdictions in which we are targeting the sale of our products and the commercialization of our product candidates. Any increase in such negative perceptions or any restrictive government regulations in response thereto, could have a negative effect on our business and may delay or impair the sale of our products or the development or commercialization of our product candidates. Even in light of compliance with regulatory protocols or following receipt of confirmation of non- regulated status in a jurisdiction, public pressure may lead to increased regulation of products produced using biotechnology, further legislation regarding novel trait development technologies, or administrative litigation concerning prior regulatory determinations, each of which could adversely affect our ability to sell our product or commercialize our product candidates. In addition, labeling requirements could heighten public concerns and make consumers less likely to purchase food products containing gene-edited ingredients.

If our products become adulterated, misbranded, or mislabeled, we might need to recall those items and may experience product liability claims if consumers or animals are injured.

We are targeting sale of our products in the human and animal food market segments. If our products become adulterated, misbranded, or mislabeled we may need to recall such products. A widespread product recall could result in significant losses due to the costs of a recall, the destruction of product inventory,

30

and lost sales due to the unavailability of product for a period of time. We could also suffer losses from a significant product liability judgment against us. A significant product recall or product liability case could also result in adverse publicity, damage to our reputation, and a loss of consumer or purchaser confidence in our products, which could have an adverse effect on our business, results of operations and financial condition and the value of our brands.

Products that we develop, and food containing our products, may fail to meet standards established by third-party non-GMO verification organizations, which could reduce the value of our products to customers.

Certain third-party organizations offer verification programs that seek to identify non-GMO products to consumers. These organizations verify the status of products (such as foods, beverages and vitamins) as non-GMO based on independently developed standards, and often authorize the display of specific markers or labels illustrating such status on the verified product’s packaging. Standards established by such third-party organizations for the verification of non-GMO status may differ from applicable regulatory legal standards applied by regulators in the United States. As a result, notwithstanding a determination as to the non-regulated status of a product pursuant to the regulatory procedures of the Animal and Plant Health Inspection Service (APHIS) of the U.S. Department of Agriculture (“USDA”) (or a similar determination in other jurisdictions), our products, and third-party products that utilize our gene-edited products as ingredients, may fail to meet more restrictive or non-scientific standards imposed by these independent verification organizations.

If we are sued for defective products and if such lawsuits were determined adversely, we could be subject to substantial damages, for which insurance coverage is not available.

We may be held liable if any product we develop, or any product that uses or incorporates any of our technologies, is found unsuitable during marketing, sale or consumption. For example, the detection of an unintended trait in a commercial seed variety or the crops and products produced may result in governmental actions such as mandated crop destruction, product recalls or environmental cleanup or monitoring. Concerns about seed quality could also lead to additional regulations being imposed on our business, such as regulations related to testing procedures, mandatory governmental reviews of biotechnology advances, or additional regulations relating to the integrity of the food supply chain from the farm to the finished product.

Benson Hill has identified a material weakness in its internal control over financial reporting. If Benson Hill is unable to remediate the material weakness, or if Benson Hill identifies additional material weaknesses in the future or otherwise fails to maintain an effective system of internal control over financial reporting, this may result in material misstatements or restatements of Benson Hill’s consolidated financial statements or cause Benson Hill to fail to meet its periodic reporting obligations.

As a public company, Benson Hill will be required to provide management’s attestation on internal control over financial reporting. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that will be applicable after the Business Combination. If Benson Hill is not able to implement the additional requirements of Section 404(a) of the Sarbanes-Oxley Act in a timely manner or with adequate compliance, it may not be able to assess whether its internal control over financial reporting is effective, which may subject it to adverse regulatory consequences and could harm investor confidence.

In connection with the preparation and audit of Benson Hill’s consolidated financial statements as of December 31, 2020 and 2019 and for each of the years ended December 31, 2020, 2019 and 2018, a material weakness was identified in its internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of Benson Hill’s annual or interim financial statements will not be prevented or detected on a timely basis.

Benson Hill did not design or maintain an effective control environment commensurate with its financial reporting requirements. Specifically, Benson Hill did not maintain a sufficient complement of personnel to appropriately analyze, record and disclose accounting matters commensurate with its accounting and reporting requirements. Further, Benson Hill did not design and maintain formal accounting policies,

31

procedures and controls over significant accounts and disclosures to achieve complete, and accurate financial accounting, reporting and disclosures.

The material weakness related to formal accounting policies, procedures and controls resulted in adjustments to certain accounts and disclosures. The material weakness could result in a misstatement of account balances or disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected.

Benson Hill has begun implementation of a plan to remediate these material weaknesses. These remediation measures are ongoing and include hiring additional accounting and financial reporting personnel and implementing additional policies, procedures and controls.

In order to maintain and improve the effectiveness of its internal control over financial reporting, Benson Hill has expended, and anticipates that New Benson Hill will continue to expend, significant resources, including accounting-related costs and significant management oversight. New Benson Hill’s independent registered public accounting firm is not required to formally attest to the effectiveness of its internal control over financial reporting until after it is no longer an “emerging growth company” as defined in the JOBS Act. At such time, New Benson Hill’s independent registered public accounting firm may issue a report that is adverse in the event it is not satisfied with the level at which its internal control over financial reporting is documented, designed, or operating. Any failure to maintain effective disclosure controls and internal control over financial reporting could adversely affect the business and operating results after the Business Combination and could cause a decline in the price of New Benson Hill Common Stock.

We may need to raise additional funding to achieve our goals, and a failure to obtain this necessary capital when needed on acceptable terms, or at all, may force us to delay, limit, reduce or terminate our product development efforts or other operations.

Since our inception, substantially all of our resources have been dedicated to the development of our core technology and product platforms, including purchases of property, plant and equipment. We believe that we will continue to expend substantial resources for the foreseeable future as we build and enhance our capabilities and commercialize our products. These expenditures are expected to include costs associated with research and development, manufacturing and supply, as well as marketing and selling existing and new products. In particular, the high-tech greenhouse agriculture business is extremely capital intensive, and we expect to expend significant resources to complete the buildout of our facilities. These expenditures are expected to include working capital, costs of acquiring and building out new facilities, costs associated with planting and harvesting, such as the purchase of seeds and growing supplies, and the cost of attracting and retaining a skilled local labor force. In addition, other anticipated costs may arise due to the unique nature of these controlled environment agriculture facilities. In addition, other unanticipated costs may arise.

As of June 30, 2021, we had cash and cash equivalents of $13.0 million and marketable securities of $29.6 million, term debt and notes payable of $28.9 million and an accumulated deficit of $204.1 million. During the six months ended June 30, 2021, the Company incurred a net loss of $49.8 million, had negative cash flows from operating activities of $47.3 million, and violated certain financial covenants under its term debt agreement, which were subsequently amended or waived, as applicable. As a result of these conditions, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are available to be issued.

The Company’s business prospects are subject to risks, expenses, and uncertainties frequently encountered by companies in the early stages of commercial operations. To date, the Company has been funded primarily by equity and debt financings, including the issuance of redeemable convertible preferred stock and term debt, as well as the use of a revolving line of credit, which is subject to renewal in September of 2021. Certain of these debt financings require the Company’s wholly-owned subsidiary, Dakota Dry Bean, to comply with financial covenants that will likely require financial support from Benson Hill, the Parent Company, to remain in compliance with the financial covenants during 2021. Further, these same debt financings require the Parent Company to maintain a minimum cash balance. If the Company further breaches these covenants, the holder of the debt may declare all amounts immediately due and payable. If the covenants are further breached, the Company plans to attempt to secure a waiver of the covenants or an amendment that modifies the covenants but there are no assurances that the Company will be able to

32

comply with its future covenants without such a waiver or that the Company will be successful in obtaining a waiver or an amendment during 2021.

The attainment of profitable operations is also dependent upon future events, including obtaining adequate financing to complete and commercialize the Company’s research and development activities, obtaining adequate grower relationships, building its customer base, successfully executing its business and marketing strategy and hiring appropriate personnel.

Based on our history of losses, we do not expect that we will be able to fund our longer-term capital and liquidity needs to execute our business plan and pursue our strategic goals through our cash balances and operating cash flow alone. To fund our longer-term capital and liquidity needs, we expect we will need to secure additional capital. However, our business plan and financing needs are subject to change depending on, among other things:

•

the number and characteristics of any additional products or manufacturing processes we develop or acquire to serve new or existing markets;

•

the scope, progress, results and costs of researching and developing future products or improvements to existing products or manufacturing processes;

•

the expenses associated with our sales and marketing initiatives;

•

our investment in manufacturing to expand our manufacturing and production capacity;

•

the costs required to fund domestic and international growth;

•

any lawsuits related to our products or commenced against us;

•

the expenses needed to attract and retain skilled personnel;

•

the costs associated with being a public company;

•

the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing intellectual property claims, including litigation costs and the outcome of such litigation; and

•

the timing, receipt and amount of sales of, or royalties on, any future approved products, if any.

We may obtain future additional funds through public or private equity or debt financings or other sources, such as strategic collaborations. Such financings may result in dilution to stockholders, issuance of securities with priority as to liquidation and dividend and other rights more favorable than common stock, imposition of debt covenants and repayment obligations, or other restrictions that may adversely affect our business. In addition, we may seek additional capital due to favorable market conditions or strategic considerations even if we believe that we have sufficient funds for current or future operating plans. There can be no assurance that financing will be available to us on favorable terms, or at all. The inability to obtain financing when needed may make it more difficult for us to operate our business or implement our growth plans and we may be required to delay, limit, reduce or terminate our manufacturing, research and development activities, growth and expansion plans, establishment of sales and marketing capabilities or other activities that may be necessary to generate revenue and achieve profitability.

We depend on key management personnel and attracting, training and retaining other qualified personnel, and our business could be harmed if we lose key management personnel or cannot attract, train and retain other qualified personnel.

Our success and future growth depend largely upon the technical skills and continued service of our executive officers as well as other key employees. These executives and key employees have been primarily responsible for determining the strategic direction of the business and executing our growth strategy and are integral to our brand, culture and reputation with distributors and others in the industry. From time to time, there may be changes in our executive management team or other key employees resulting from the hiring or departure of these personnel. The loss of one or more executive officers or the failure by the executive team to effectively work with employees and lead the company, could harm our business.

Additionally, the majority of our personnel is involved in research, development, and regulatory activities and competition for these highly skilled employees is intense. Our business is therefore dependent on our

33

ability to recruit, train and retain a highly skilled and educated workforce with expertise in a range of disciplines, including biology, biochemistry, plant genetics, agronomics, mathematics, agribusiness, and other subjects relevant to our operations. If we are unable to hire and retain skilled and highly educated personnel could limit our growth and hinder our research and development efforts. There can be no assurance that we will be successful in attracting or retaining such personnel and the failure to do so could have a material adverse effect on our business, financial condition, and results of operations.

Further, our success depends in part upon our ability to attract, train and retail a sufficient number of employees who understand and appreciate our culture and can represent our brand effectively and establish credibility with our business partners and consumers. We believe a critical component of our success has been our company culture and long-standing core values. We have invested substantial time and resources in building our team. If we are unable to hire and retain employees capable of meeting our business needs and expectations, or if we fail to preserve our company culture among a larger number of employees dispersed in various geographic regions as we continue to grow and develop the infrastructure associated with being a more mature public company, our business and brand image may be impaired. Any failure to meet our staffing needs or any material increase in turnover rates of our employees may adversely affect our business, results of operations and financial condition.

Our management has limited experience in operating a public company.

Our executive officers have limited experience in the management of a publicly traded company. Our management team may not successfully or effectively manage our transition to a public company that will be subject to significant regulatory oversight and reporting obligations under federal securities laws. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management and growth of our company. We may not have adequate personnel with the appropriate level of knowledge, experience, and training in the accounting policies, practices or internal controls over financial reporting required of public companies in the United States. The development and implementation of the standards and controls necessary for us to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public company, which will increase out operating costs in future periods.

We will incur increased costs as a result of operating as a public company, and our management will devote substantial time to new compliance initiatives.

As a public company, we will incur significant legal, accounting and other expenses that we did not incur as a private company, and these expenses may increase even more after we are no longer an emerging growth company, as defined in Section 2(a) of the Securities Act. As a public company, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), the Dodd-Frank Wall Street Reform and Consumer Protection Act, as well as rules adopted, and to be adopted, by the SEC and NYSE. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, we expect these rules and regulations to substantially increase our legal and financial compliance costs and to make some activities more time-consuming and costly. The increased costs will increase our net loss. For example, we expect these rules and regulations to make it more difficult and more expensive for it to obtain director and officer liability insurance and we may be forced to accept reduced policy limits or incur substantially higher costs to maintain the same or similar coverage. We cannot predict or estimate the amount or timing of additional costs we may incur to respond to these requirements. The impact of these requirements could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as executive officers.

We rely on information technology systems and any inadequacy, failure, interruption or security breaches of those systems may harm our ability to effectively operate our business.

We are dependent on various information technology systems, including, but not limited to, networks, applications and outsourced services in connection with the current and planned operation of our business.

34

A failure of these information technology systems to perform as anticipated could cause our business to suffer. In addition, our information technology systems may be vulnerable to damage or interruption from circumstances beyond our control, including fire, natural disasters, systems failures, viruses and security breaches. Any such damage or interruption could negatively impact our business.

The extent to which the COVID-19 pandemic and resulting deterioration of worldwide economic conditions adversely impact our business, financial condition, and operating results will depend on future developments, which are difficult to predict.

As a result of the COVID-19 pandemic, governmental authorities have implemented numerous and rapidly evolving measures to try to contain the virus, such as travel bans and restrictions, limits on gatherings, quarantines, shelter-in-place orders, and business shutdowns. In response to the COVID-19 pandemic and in accordance with governmental orders, we have also modified our business practices and implemented proactive measures to protect the health and safety of employees, including restricting employee travel, requiring, at times, remote work arrangements for non-laboratory employees, implementing social distancing, and enhanced sanitary measures in our headquarters, and cancelling attendance at events and conferences. Many of the suppliers, vendors, and service providers on whom we rely on have made similar modifications. To date, with the exception of us modifying our physical business practices, including lower travel, and delays in the receipt of certain laboratory supplies and the performance of related services, we have not experienced a material impact on business operations from the effects of COVID-19. There is no certainty measures implemented by government authorities will be sufficient to mitigate the risks posed by, or the impacts and disruptions of, the COVID-19 pandemic.

As a result of the COVID-19 pandemic and government actions to contain it, related volatility in the financial markets and deterioration of national and global economic conditions, we could experience material adverse operational and financial impacts, including:

•

overall lower expenditures by potential commercial partners as a result of challenging economic circumstances arising from the COVID-19 pandemic and potentially continuing after the immediate crisis subsides;

•

disruptions and delays to our R&D pipeline resulting from a shutdown of our headquarters due to expanded governmental restrictions or illness among our personnel as a result of COVID-19, increased absenteeism among employees, or delays with respect to raw materials necessary for our R&D activities;

•

interruptions or delays in seed production or grain sales resulting from supply chain disruptions, including as a result of restrictions or disruptions to transportation or operational disruptions at warehousing, storage, crushing and/or refining facilities;

•

overall reduced operational productivity resulting from challenges associated with remote work arrangements, limited resources available to our employees (particularly with respect to our business development employees for whom in-person access to our customers and customer prospects has been significantly limited) and increased cybersecurity risks as a result of remote access to our information systems; and

•

constraints on financing opportunities resulting from dislocations in the capital markets, which may make it too costly or difficult for us to pursue public or private equity or debt financings on acceptable terms.

The degree to which COVID-19 impacts our business and results will depend on future developments, which are highly uncertain and cannot be predicted, including, but not limited to, the severity, duration and geographic spread of the outbreak, and the global, national, and regional actions to contain the virus and address its impact, including travel restrictions imposed, business closures or business disruption.

The resumption of normal business operations after interruptions caused by COVID-19 may be delayed or constrained by lingering effects of COVID-19 on us or our suppliers, third-party service providers, counterparties in collaboration arrangement or licenses, or customers. Even after the COVID-19 outbreak has subsided, we may experience material and adverse impacts on its business, operating results, and financial

35

condition as a result of the global economic impact of COVID-19 outbreak, including any recession that has occurred or may occur in the future.

The impact of COVID-19 may also exacerbate other risks discussed in this “Risk Factors” section, any of which could have a material effect on us. This situation is changing rapidly, and additional impacts may arise that we are not aware of currently.

Disruptions in the worldwide economy may adversely affect our business, results of operations and financial condition.

The global economy can be negatively impacted by a variety of factors such as the spread or fear of spread of contagious diseases (such as the recent COVID-19 pandemic) in locations where our products are sold, man-made or natural disasters, actual or threatened war, terrorist activity, political unrest, civil strife and other geopolitical uncertainty. Such adverse and uncertain economic conditions may impact distributor, retailer, foodservice and consumer demand for our products. In addition, our ability to manage normal commercial relationships with our suppliers, co-manufacturers, distributors, retailers, restaurant and foodservice customers and consumers and creditors may suffer. Consumers may shift purchases to lower-priced or other perceived value offerings during economic downturns as a result of various factors, including job losses, inflation, higher taxes, reduced access to credit, change in federal economic policy and recent international trade disputes. In particular, consumers may reduce the amount of plant-based food products that they purchase where there are conventional animal-based protein offerings, which generally have lower retail prices. In addition, consumers may choose to purchase private label products rather than branded products because they are generally less expensive. A decrease in consumer discretionary spending may also result in consumers reducing the frequency and amount spent on food prepared away from home. Distributors, retailers and foodservice customers may become more conservative in response to these conditions and seek to reduce their inventories. Our results of operations depend upon, among other things, our ability to maintain and increase sales volume with our existing distributors, retailer and foodservice customers, our ability to attract new consumers, the financial condition of our consumers and our ability to provide products that appeal to consumers at the right price. Decreases in demand for our products without a corresponding decrease in costs would put downward pressure on margins and would negatively impact our financial results. Prolonged unfavorable economic conditions or uncertainty may have an adverse effect on our sales and profitability and may result in consumers making long-lasting changes to their discretionary spending behavior on a more permanent basis.

The estimates and assumptions on which our financial projections are based may prove to be inaccurate, which may cause our actual results to materially differ from such projections, and which may adversely affect our future profitability, cash flows and the market price of our common stock.

Our financial projections included in this proxy statement/prospectus under “The Merger — Unaudited Prospective Financial Information of Benson Hill” are dependent on certain estimates and assumptions related to, among other things, growth assumptions that are inherently subject to significant uncertainties and contingencies, as well as, among other things, matters related specifically to the recent operational performance and anticipated development of our business, and are subject to significant economic, competitive, industry and other uncertainties, and may not be achieved in full, at all, or within projected timeframes. The financial projections also reflect numerous assumptions with respect to general business, economic, market, regulatory and financial conditions and various other factors, all of which are difficult to predict and many of which are beyond our control. Furthermore, the financial projections do not take into account any circumstances or event occurring after the date they were prepared. The financial projections were not prepared with a view toward public disclosure, nor was it prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the Public Company Accounting Oversight Board for preparation and presentation of prospective financial information. Accordingly, none of STPC, WithumSmith+Brown, PC, STPC’s independent registered public accounting firm, and Ernst & Young LLP, Benson Hill’s independent registered accounting firm, nor any other independent accountants, has compiled, examined or performed any procedures with respect to the financial projections contained herein, nor have they expressed any opinion or any other form of assurance on such projections or their achievability. The report of the independent registered public accounting firm to Benson Hill, Inc. contained in the audited financial statements for the year ended December 31, 2020, which is included in this

36

proxy statement/prospectus, relates to historical financial information of Benson Hill, and such report does not extend to the financial projections included below and should not be read to do so. The financial projections were based on historical experience and on various other estimates and assumptions that our management believed to be reasonable under the circumstances and at the time they were made. There will be differences between actual and projected financial results, and actual results may be materially greater or materially less than those contained in the financial projections, especially in light of the increased difficulty in making such estimates and assumptions as a result of the COVID-19 pandemic. Any material variation between our financial projections and our actual results may adversely affect our future profitability, cash flows and the market price of our common stock. See “The Merger — Unaudited Prospective Financial Information of Benson Hill” beginning on page 147.

Future acquisitions or investments could disrupt our business and harm our financial condition.

In the future, we may pursue acquisitions or investments that we believe will help us achieve our strategic objectives. We may not be able to find suitable acquisition candidates, and even if we do, we may not be able to complete acquisitions on favorable terms, if at all. If we do complete acquisitions, we may not ultimately achieve our goals or realize the anticipated benefits. The pursuit of acquisitions and any integration process will require significant time and resources and could divert management time and focus from operation of our then-existing business, and we may not be able to manage the process successfully. Any acquisitions we complete could be viewed negatively by our customers or consumers. An acquisition, investment or business relationship may result in unforeseen operating difficulties and expenditures, including disrupting our ongoing operations and subjecting us to additional liabilities, increasing our expenses, and adversely impacting our business, financial condition and operating results. Moreover, we may be exposed to unknown liabilities related to the acquired company or product, and the anticipated benefits of any acquisition, investment or business relationship may not be realized if, for example, we fail to successfully integrate such acquisition into our company. To pay for any such acquisitions, we would have to use cash, incur debt, or issue equity securities, each of which may affect our financial condition or the value of our common stock and could result in dilution to our stockholders. If we incur more debt it would result in increased fixed obligations and could also subject us to covenants or other restrictions that would impede our ability to manage our operations. Our acquisition strategy could require significant management attention, disrupt our business and harm our business, financial condition and results of operations.

Risks Relating to Our Industry

The overall agricultural industry is susceptible to commodity price changes and we are exposed to market risks from changes in commodity prices.

Conditions in the U.S. agricultural industry significantly impact our operating results. Changes in the prices of commodities products could result in higher overall cost along the agricultural supply chain, which may negatively affect our ability to commercialize our products. We will be susceptible to changes in costs in the agricultural industry as a result of factors beyond our control, such as general economic conditions, seasonal fluctuations, weather conditions, demand, food safety concerns, product recalls and government regulations. As a result, we may not be able to anticipate or react to changing costs by adjusting our practices, which could cause our operating results to deteriorate.

Adverse weather conditions, natural disasters, crop disease, pests and other natural conditions can impose significant costs and losses on our business.

The ability to grow our products is vulnerable to adverse weather conditions, including windstorms, floods, drought and temperature extremes, which are quite common but difficult to predict, the effects of which may be influenced and intensified by ongoing global climate change. Unfavorable growing conditions can reduce both crop size and crop quality. In extreme cases, entire harvests may be lost in some geographic areas. Such adverse conditions can result in harvesting delays or loss of crops for farmers and cause us to be delayed, or to fail entirely in delivering product to customers, resulting in loss of revenue. Furthermore, significant fluctuations in market prices for agricultural inputs and crops could also have an adverse effect on the prices of our products.

37

The ability to grow our products is also vulnerable to crop disease and to pests, which may vary in severity and effect, depending on the stage of production at the time of infection or infestation, the type of treatment applied, climatic conditions and the risks associated with ongoing global climate change. The costs to control disease and other infestations vary depending on the severity of the damage and the extent of the plantings affected. Moreover, there can be no assurance that available technologies to control such infestations will continue to be effective. These infestations can also increase costs, decrease revenues and lead to additional charges to earnings, which may have a material adverse effect on our business, financial position and results of operations.

Risks Relating to Regulatory and Legal Matters

The regulatory environment in the United States for our current and future products is uncertain and evolving.

Changes in applicable regulatory requirements could result in a substantial increase in the time and costs associated with developing our products and negatively impact our operating results. While the USDA and U.S. Food and Drug Administration (“FDA”) currently have petition processes that we have successfully completed in the past, these processes and the manner in which the USDA and FDA interpret their own regulations may change in the future, negatively impacting our speed to market and cost to launch product candidates. We cannot predict whether advocacy groups will challenge existing regulations and USDA or FDA determinations or whether the USDA or FDA will alter the manner in which it interprets its own regulations or institutes new regulations, or otherwise modifies regulations in a way that will subject our products to more burdensome standards, thereby substantially increasing the time and costs associated with developing our product candidates.

The regulatory environment outside the United States varies greatly from jurisdiction to jurisdiction and there is less certainty how our products will be regulated.

The regulatory environment around gene editing in plants for food ingredients is greatly uncertain outside of the United States and varies greatly from jurisdiction to jurisdiction. Each jurisdiction may have its own regulatory framework regarding genetically modified foods, which may include restrictions and regulations on planting and growing genetically modified plants and in the consumption and labeling of genetically modified foods, and which may encapsulate our products. To the extent regulatory frameworks outside of the United States are not receptive to our gene-editing technologies, this may limit our ability to expand into other global markets.

Complying with the regulatory requirements outside the United States will be costly and time-consuming, and there is no guarantee we will be able to commercialize our products outside the United States.

We cannot predict whether or when any jurisdiction will change its regulations with respect to our products. Advocacy groups have engaged in publicity campaigns and filed lawsuits in various countries against companies and regulatory authorities, seeking to halt regulatory approval or clearance activities or influence public opinion against genetically engineered and/or gene-edited products. In addition, governmental reaction to negative publicity concerning our products could result in greater regulation of genetic research and derivative products or regulatory costs that render our products cost prohibitive.

The scale of the commodity food and agricultural industry may make it difficult to monitor and control the distribution of our products. As a result, our products may be sold inadvertently within jurisdictions where they are not approved for distribution. Such sales may lead to regulatory challenges or lawsuits against us, which could result in significant expenses and management attention.

Government policies and regulations, particularly those affecting the agricultural sector and related industries, could adversely affect our operations and profitability.

Agricultural production and trade flows are subject to government policies and regulations. Governmental policies and approvals of technologies affecting the agricultural industry, such as taxes, tariffs, duties, subsidies, incentives and import and export restrictions on agricultural commodities and commodity products can influence the planting of certain crops, the location and size of crop production,

38

and the volume and types of imports and exports. In addition, as we grow our business, we may be required to secure additional permits and licenses. For example, we get a seed permit from each state where we sell seed and, as we expand into additional states, we will be required to acquire seed permits in those additional states. Finally, future government policies in the United States or in other countries may discourage our customers from using our products or encourage the use of products more advantageous to our competitors, which would put us at a commercial disadvantage and could negatively impact our future revenues and results of operations.

We may use biological materials in our business and are subject to numerous environmental, health and safety laws and regulations. Compliance with such laws and regulations and any claims relating to improper handling, storage or disposal of these materials could be time consuming and costly.

We are subject to numerous federal, state, local and foreign environmental, health and safety laws and regulations, including those governing laboratory procedures, the handling, use, storage, treatment, manufacture and disposal of hazardous materials and wastes, discharge of pollutants into the environment and human health and safety matters. Our R&D processes involve the controlled use of hazardous materials, including biological materials. We may be sued for any injury or contamination that results from our use or the use by third parties of these materials, or may otherwise be required to remediate such contamination, and our liability may exceed any insurance coverage and our total assets. Compliance with environmental, health and safety laws and regulations may be expensive and may impair our R&D efforts. If we fail to comply with these requirements, we could incur substantial costs and liabilities, including civil or criminal fines and penalties, clean-up costs or capital expenditures for control equipment or operational changes necessary to achieve and maintain compliance. In addition, we cannot predict the impact on our business of new or amended environmental, health and safety laws or regulations or any changes in the way existing and future laws and regulations are interpreted and enforced. These current or future laws and regulations may impair our research, development or production efforts or result in increased expense of compliance.

Litigation or legal proceedings could expose us to significant liabilities and have a negative impact on our reputation or business.

From time to time, we may be party to various claims and litigation proceedings. We evaluate these claims and litigation proceedings to assess the likelihood of unfavorable outcomes and to estimate, if possible, the amount of potential losses. Based on these assessments and estimates, we may establish reserves, as appropriate. These assessments and estimates are based on the information available to management at the time and involve a significant amount of management judgment. Actual outcomes or losses may differ materially from our assessments and estimates. We are not currently party to any material litigation. Even when not merited, the defense of these lawsuits may divert management’s attention, and we may incur significant expenses in defending these lawsuits. The results of litigation and other legal proceedings are inherently uncertain, and adverse judgments or settlements in some of these legal disputes may result in adverse monetary damages, penalties or injunctive relief against us, which could negatively impact our financial position, cash flows or results of operations. Any claims or litigation, even if fully indemnified or insured, could damage our reputation and make it more difficult to compete effectively or to obtain adequate insurance in the future.

Furthermore, while we maintain insurance for certain potential liabilities, such insurance does not cover all types and amounts of potential liabilities and is subject to various exclusions as well as caps on amounts recoverable. Even if we believe a claim is covered by insurance, insurers may dispute our entitlement to recovery for a variety of potential reasons, which may affect the timing and, if the insurers prevail, the amount of our recovery.

Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the merger or other ownership changes.

We have incurred losses during our history and do not expect to become profitable in the near future and may never achieve profitability. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. As of December 31, 2020, we had U.S. federal net operating loss carryforwards of approximately $136.9 million.

39

Under the Tax Cuts and Jobs Act (the “Tax Act”), as modified by the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), U.S. federal net operating loss carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to the Tax Act or the CARES Act.

In addition, our net operating loss carryforwards are subject to review and possible adjustment by the U.S. Internal Revenue Services (the “IRS”), and state tax authorities. Under Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), our federal net operating loss carryforwards and other tax attributes may become subject to an annual limitation in the event of certain cumulative changes in our ownership. An “ownership change” pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Our ability to utilize our net operating loss carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including potential changes in connection with the business combination or other transactions. Similar rules may apply under state tax laws. We have not yet determined the amount of the cumulative change in our ownership resulting from the merger or other transactions, or any resulting limitations on our ability to utilize our net operating loss carryforwards and other tax attributes. If we earn taxable income, such limitations could result in increased future income tax liability to us and our future cash flows could be adversely affected. We have recorded a valuation allowance related to our net operating loss carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets.

Risks Relating to Intellectual Property

Patents and patent applications involve highly complex legal and factual questions, which, if determined adversely to us, could negatively impact our competitive position.

The patent positions of biotechnology companies and other actors in our fields of business can be highly uncertain and involve complex scientific, legal and factual analyses. The interpretation and breadth of claims allowed in some patents covering biological compositions may be uncertain and difficult to determine and are often affected materially by the facts and circumstances that pertain to the patented compositions and the related patent claims. The issuance and scope of patents cannot be predicted with certainty. Patents, if issued, may be challenged, invalidated, narrowed or circumvented. Challenges to our or our licensors’ patents and patent applications, if successful, may result in the denial of our or our licensors’ patent applications or the loss or reduction in their scope. In addition, defending against such challenges may be costly and involve the diversion of significant management time. Accordingly, rights under any of our patents may not provide us with enough protection against competitive products or processes and any loss, denial or reduction in scope of any of such patents and patent applications may have a material adverse effect on our business.

Even if not challenged, our patents and patent applications may not adequately protect our product candidates or technology or prevent others from designing their products or technology to avoid being covered by our patent claims. If the breadth or strength of protection provided by the patents we own or license is threatened, it could dissuade companies from partnering with us to develop, and could threaten our ability to successfully commercialize, our product candidates.

If we fail to obtain and maintain patent protection and trade secret protection of our product candidates and technology, we could lose our competitive advantage and competition we face would increase, reducing any potential revenues and have a material adverse effect on our business.

We will not seek to protect our intellectual property rights in all jurisdictions throughout the world and we may not be able to adequately enforce our intellectual property rights even in the jurisdictions where we seek protection.

Filing, prosecuting and defending patents in all countries and jurisdictions throughout the world would be prohibitively expensive. Patent prosecution must be sought on a country-by-country basis, which is an

40

expensive and time-consuming process with uncertain outcomes. Our intellectual property rights in some countries outside the United States could be less extensive than those in the United States, assuming that rights are obtained in the United States. In addition, the laws of some foreign countries do not protect intellectual property rights to the same extent as federal and state laws in the United States. Consequently, we may not be able to prevent third parties from practicing our inventions in all countries outside the United States, or from selling or importing products made using our inventions in and into the United States or other jurisdictions.

Competitors may use our technologies in jurisdictions where we or our licensors do not pursue and obtain patent protection. Further, competition may export otherwise infringing products to territories where we or our licensors have patent protection, but where the ability to enforce those patent rights is not as strong as in the United States. These products may compete with our products and our intellectual property rights and such rights may not be effective or enough to prevent such competition.

In addition, changes in, or different interpretations of, patent laws in the United States and other countries may permit others to use our discoveries or to develop and commercialize our technology and products without providing any notice or compensation to us or may limit the scope of patent protection that we or our licensors are able to obtain. The laws of some countries do not protect intellectual property rights to the same extent as United States laws and those countries may lack adequate rules and procedures for defending our intellectual property rights.

Furthermore, proceedings to enforce our patent rights and other intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, could put our or our licensors’ patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate, and the damages or other remedies awarded to us, if any, may not be commercially meaningful, while the damages and other remedies we may be ordered to pay such third parties may be significant. Accordingly, our efforts to enforce our intellectual property rights around the world may be inadequate to obtain a significant commercial advantage from the intellectual property that we develop or license.

Third parties may assert rights to inventions we develop or otherwise regard as our own.

Third parties may in the future make claims challenging the inventorship or ownership of our or our licensors’ intellectual property. We may face claims by third parties that our agreements with employees, contractors, or consultants obligating them to assign intellectual property to us are ineffective or are in conflict with prior or competing contractual obligations of assignment. Litigation may be necessary to resolve an ownership dispute, and if we are not successful, we may be precluded from using certain intellectual property and associated products and technology or may lose our rights in that intellectual property.

We may be unsuccessful in developing, licensing or acquiring intellectual property that may be required to develop and commercialize our product candidates.

Our programs may involve additional product candidates that may require the use of intellectual property or proprietary rights held by third parties; the growth of our business may depend in part on our ability to acquire, in-license or use these intellectual property and proprietary rights.

However, we may be unable to acquire or in-license any third-party intellectual property or proprietary rights that may be key to development. Even if we can acquire or in-license such rights, we may be unable to do so on commercially reasonable terms. The licensing and acquisition of third-party intellectual property and proprietary rights is a competitive area, and several more established companies are also pursuing strategies to license or acquire third-party intellectual property and proprietary rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources and agricultural development and commercialization capabilities.

In addition, companies that perceive us to be a competitor may be unwilling to assign or license intellectual property and proprietary rights to us. We also may be unable to license or acquire third-party intellectual property and proprietary rights on terms that would allow us to make an appropriate return on

41

our investment or at all. If we are unable to successfully acquire or in-license rights to required third-party intellectual property and proprietary rights or maintain the existing intellectual property and proprietary rights we have, we may have to cease development of the relevant program, product or product candidate, which could have a material adverse effect on our business.

Risks Relating to the Merger

STPC public stockholders will have a reduced ownership and voting interest after the merger and will exercise less influence over management.

Upon the issuance of the New Benson Hill Common Stock to Benson Hill stockholders as merger consideration, current STPC public stockholders’ percentage ownership will be diluted. Subject to the assumptions set forth under “Basis of Presentation and Glossary” and assuming no public stockholders exercise their redemption rights, current STPC public stockholders’ percentage ownership in New Benson Hill following the issuance of shares to Benson Hill stockholders as merger consideration and after giving effect to the PIPE Investment would be 19.2%. Under the same assumptions and assuming that 40,250,000 shares of Class A Common Stock (the maximum number of shares of Class A Common Stock that could be redeemed in connection with the merger) are redeemed in connection with the merger and excluding any shares issuable pursuant to STPC’s outstanding warrants, current STPC public stockholders would not have any ownership in New Benson Hill following the issuance of shares of New Benson Hill Common Stock to Benson Hill stockholders as merger consideration. Additionally, of the expected members of the New Benson Hill board of directors after the completion of the merger, only two will be current directors of STPC or appointed by current stockholders of STPC and the rest will be current directors of Benson Hill or appointed by current stockholders of Benson Hill. The percentage of New Benson Hill Common Stock that will be owned by current STPC public stockholders as a group will vary based on the number of shares of Class A Common Stock for which the holders thereof request redemption in connection with the merger. To illustrate the potential ownership percentages of current STPC public stockholders under different redemption levels, based on the number of issued and outstanding shares of STPC common stock, Existing Benson Hill Common Stock and Benson Hill Preferred Stock on            , 2021, current STPC public stockholders, as a group, will own (1) if there are no redemptions, 19.2% of New Benson Hill Common Stock expected to be outstanding immediately after the merger and after giving effect to the PIPE Investment or (2) if there are redemptions of 100% of the outstanding shares of STPC common stock (which is the maximum amount of redemptions that would satisfy STPC having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act)), no shares of the New Benson Hill Common Stock expected to be outstanding immediately after the merger. Because of this, current STPC public stockholders, as a group, will have less influence on the board of directors, management and policies of New Benson Hill than they now have on the board of directors, management and policies of STPC.

The market price of shares of New Benson Hill Common Stock after the merger may be affected by factors different from those currently affecting the prices of shares of Class A Common Stock.

Upon completion of the merger, holders of shares of Existing Benson Hill Common Stock and Benson Hill Preferred Stock will become holders of shares of New Benson Hill Common Stock. Prior to the merger, STPC has had limited operations. Upon completion of the merger, New Benson Hill’s results of operations will depend upon the performance of Benson Hill’s businesses, which are affected by factors that are different from those currently affecting the results of operations of STPC.

STPC has not obtained an opinion from an independent investment banking firm, and consequently, there is no assurance from an independent source that the merger consideration is fair to its stockholders from a financial point of view.

STPC is not required to, and has not, obtained an opinion from an independent investment banking firm that the merger consideration it is paying for Benson Hill is fair to STPC’s stockholders from a financial point of view. The fair market value of Benson Hill has been determined by STPC’s board of directors based upon the financial analysis of Benson Hill generally used to approve the transactions. Specifically, the board determined that the consideration being paid in the merger, which amount was negotiated at arm’s

42

length, was fair to and in the best interests of STPC and its stockholders and appropriately reflected Benson Hill’s value. In reaching this determination, the board concluded that it was appropriate to base such valuation in part on qualitative factors such as management strength and depth, competitive positioning, customer relationships, and technical skills, as well as quantitative factors such as Benson Hill’s historical growth rate and its potential for future growth in revenue and profits. STPC’s stockholders will be relying on the judgment of its board of directors with respect to such matters.

Because Benson Hill will become a publicly traded company through a merger as opposed to an underwritten public offering, no underwriter has conducted due diligence in connection with the transaction.

In an underwritten public offering, underwriters typically conduct due diligence on the issuer in order to establish a due diligence defense against liability claims under federal securities laws. Because STPC is already a publicly traded company, no underwriter has conducted due diligence in connection with the transaction. While sponsors, private investors and management in a business combination undertake a certain level of due diligence, it is not necessarily the same level of due diligence undertaken by an underwriter in an underwritten public offering and, therefore, there could be a heightened risk of an incorrect valuation of the business or material misstatements or omissions in this proxy statement/prospectus.

If the merger’s benefits do not meet the expectations of financial analysts, the market price of New Benson Hill Common Stock may decline.

The market price of the New Benson Hill Common Stock may decline as a result of the merger if New Benson Hill does not achieve the perceived benefits of the merger as rapidly, or to the extent anticipated by, financial analysts or the effect of the merger on New Benson Hill’s financial results is not consistent with the expectations of financial analysts. Accordingly, holders of New Benson Hill Common Stock may experience a loss as a result of a decline in the market price of New Benson Hill Common Stock. In addition, a decline in the market price of New Benson Hill Common Stock could adversely affect New Benson Hill’s ability to issue additional securities and to obtain additional financing in the future.

The consummation of the merger is subject to a number of conditions and if those conditions are not satisfied or waived, the merger agreement may be terminated in accordance with its terms and the merger may not be completed.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include: approval of the proposals required to effect the merger by STPC stockholders, as well as receipt of all requisite regulatory approvals, absence of orders prohibiting completion of the merger, effectiveness of the registration statement of which this proxy statement/prospectus is a part, approval of the shares of New Benson Hill Common Stock to be issued to Benson Hill stockholders for listing on the NYSE, meeting the Minimum Cash Condition, the accuracy of the representations and warranties by both parties (subject to the materiality standards set forth in the merger agreement) and the performance by both parties of their covenants and agreements. These conditions to the closing of the merger may not be fulfilled in a timely manner or at all, and, accordingly, the merger may not be completed. In addition, the parties can mutually decide to terminate the merger agreement at any time, before or after stockholder approval, or STPC or Benson Hill may elect to terminate the merger agreement in certain other circumstances. See “The Merger Agreement — Termination” beginning on page 185.

Termination of the merger agreement could negatively impact Benson Hill and STPC.

If the merger is not completed for any reason, including as a result of Benson Hill stockholders declining to adopt the merger agreement or STPC stockholders declining to approve the proposals required to effect the merger, the ongoing businesses of Benson Hill and STPC may be adversely impacted and, without realizing any of the anticipated benefits of completing the merger, Benson Hill and STPC would be subject to a number of risks, including the following:

•

Benson Hill or STPC may experience negative reactions from the financial markets, including negative impacts on STPC’s stock price (including to the extent that the current market price reflects a market assumption that the merger will be completed);

43

•

Benson Hill may experience negative reactions from its customers, vendors and employees;

•

Benson Hill and STPC will have incurred substantial expenses and will be required to pay certain costs relating to the merger, whether or not the merger is completed; and

•

since the merger agreement restricts the conduct of Benson Hill’s and STPC’s businesses prior to completion of the merger, each of Benson Hill and STPC may not have been able to take certain actions during the pendency of the merger that would have benefitted it as an independent company, and the opportunity to take such actions may no longer be available (see the section entitled “The Merger Agreement — Covenants and Agreements” beginning on page 173 of this proxy statement/prospectus for a description of the restrictive covenants applicable to Benson Hill and STPC).

If the merger agreement is terminated and Benson Hill’s board of directors seeks another merger or business combination, Benson Hill stockholders cannot be certain that Benson Hill will be able to find a party willing to offer equivalent or more attractive consideration than the consideration STPC has agreed to provide in the merger or that such other merger or business combination is completed. If the merger agreement is terminated and STPC’s board of directors seeks another merger or business combination, STPC stockholders cannot be certain that STPC will be able to find another acquisition target that would constitute a business combination or that such other merger or business combination will be completed. See “The Merger Agreement — Termination” on page 185.

Benson Hill will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Benson Hill and consequently on STPC. These uncertainties may impair Benson Hill’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with Benson Hill to seek to change existing business relationships with Benson Hill. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with the business, New Benson Hill’s business following the merger could be negatively impacted. In addition, the merger agreement restricts Benson Hill from making certain expenditures and taking other specified actions without the consent of STPC until the merger occurs. These restrictions may prevent Benson Hill from pursuing attractive business opportunities that may arise prior to the completion of the merger. See “The Merger Agreement — Covenants and Agreements” beginning on page 173.

STPC directors and officers may have interests in the merger different from the interests of STPC Stockholders.

Executive officers of STPC negotiated the terms of the merger agreement with their counterparts at Benson Hill, and the STPC board of directors determined that entering into the merger agreement was in the best interests of STPC and its stockholders, declared the merger agreement advisable and recommended that STPC stockholders approve the proposals required to effect the merger. In considering these facts and the other information contained in this proxy statement/prospectus, you should be aware that STPC’s executive officers and directors may have financial interests in the merger that may be different from, or in addition to, the interests of STPC stockholders. The STPC board of directors and the audit committee thereof was aware of and considered these interests, among other matters, in reaching the determination to approve the terms of the merger and in recommending to STPC’s stockholders that they vote to approve the merger. For a detailed discussion of the special interests that STPC’s directors and executive officers may have in the merger, please see the section entitled “The Merger — Interests of STPC Directors and Executive Officers in the Merger” beginning on page 166.

The merger will result in changes to the board of directors of New Benson Hill that may affect the strategy of New Benson Hill.

If the parties complete the merger, the composition of New Benson Hill board of directors will change from the current boards of directors of STPC and Benson Hill. The board of directors of New Benson Hill will consist of Daniel Jacobi, Matthew Crisp, DeAnn Brunts, J. Stephan Dolezalek, Adrienne Elsner,

44

David Lee, Craig Rohr, Anderw Wheeler and Linda Whitley-Taylor after the completion of the merger. This new composition of the New Benson Hill board of directors may affect the business strategy and operating decisions of New Benson Hill upon the completion of the merger.

The merger agreement contains provisions that may discourage other companies from trying to acquire Benson Hill for greater merger consideration.

The merger agreement contains provisions that may discourage a third-party from submitting a business combination proposal to Benson Hill that might result in greater value to Benson Hill’s stockholders than the merger or may result in a potential competing acquirer proposing to pay a lower per share price to acquire Benson Hill than it might otherwise have proposed to pay absent such provisions. These provisions include a general prohibition on Benson Hill from soliciting, or entering into discussions with any third-party regarding any acquisition proposal or offers for competing transactions. Benson Hill also has an unqualified obligation to submit the proposal to adopt the merger agreement to a vote by its stockholders, even if Benson Hill receives an alternative acquisition proposal that its board of directors believes is superior to the merger, unless the merger agreement has been terminated in accordance with its terms.

The unaudited pro forma combined financial information included in this proxy statement/prospectus is preliminary and the actual financial condition and results of operations after the merger may differ materially.

The unaudited pro forma financial information included in this proxy statement/prospectus is presented for illustrative purposes only and is not necessarily indicative of what New Benson Hill’s actual financial position or results of operations would have been had the merger been completed on the date(s) indicated. The preparation of the pro forma financial information is based upon available information and certain assumptions and estimates that STPC and Benson Hill currently believe are reasonable.

The unaudited pro forma financial information in this proxy statement/prospectus reflects adjustments which are based on a number of assumptions and estimates including, but not limited to, Benson Hill being considered the accounting acquirer in the merger, the debt obligations and the cash and cash equivalents of Benson Hill immediately following the consummation of the merger, and the number of shares of STPC Class A Common Stock that are redeemed in connection with the merger. Accordingly, such pro forma financial information may not be indicative of our future operating or financial performance and our actual financial condition and results of operations may vary materially from our pro forma results of operations and balance sheet contained elsewhere in this proxy statement/prospectus, including as a result of such assumptions not being accurate. Additionally, the final acquisition accounting adjustments could differ materially from the unaudited pro forma adjustments presented in this proxy statement/prospectus. See “Unaudited Pro Forma Combined Financial Information” beginning on page 62.

STPC and Benson Hill will incur transaction costs in connection with the merger.

Each of STPC and Benson Hill has incurred and expects that it will incur significant, non-recurring costs in connection with consummating the merger. STPC and Benson Hill may also incur additional costs to retain key employees. STPC and Benson Hill will also incur significant legal, financial advisor, accounting, banking and consulting fees, fees relating to regulatory filings and notices, SEC filing fees, printing and mailing fees and other costs associated with the merger. STPC estimates that it will incur approximately $14.1 million in deferred underwriting fees and $14.2 million in fees related to the PIPE Investment and $7.0 million in transaction costs. Benson Hill estimates that it will incur approximately $14.7 million in transaction costs associated with the merger. Some of these costs are payable regardless of whether the merger is completed. See “The Merger — Terms of the Merger” beginning on page 147.

Benson Hill’s stockholders will have their rights as stockholders governed by New Benson Hill’s organizational documents.

As a result of the completion of the merger, holders of shares of Existing Benson Hill Common Stock and Benson Hill Preferred Stock will become holders of shares of New Benson Hill Common Stock, which will be governed by New Benson Hill’s organizational documents. As a result, there will be differences between the rights currently enjoyed by Benson Hill stockholders and the rights that Benson Hill stockholders

45

who become New Benson Hill stockholders will have as stockholders of New Benson Hill. See “Comparison of Stockholders’ Rights” beginning on page 215.

If the merger does not qualify as a “reorganization” under Section 368(a) of the Code, U.S. Holders of Existing Benson Hill Common Stock may be required to pay substantial U.S. federal income taxes.

As discussed more fully under “Material U.S. Federal Income Tax Consequences,” subject to the qualifications and limitations discussed thereunder, the merger should qualify as a “reorganization” within the meaning of Section 368(a). However, such position is not binding upon the IRS or the courts, and there can be no assurance that the IRS or a court will not take a contrary position. Benson Hill and STPC do not intend to request a ruling from the IRS regarding any aspect of the U.S. federal income tax consequences of the merger. If the merger does not qualify as a “reorganization” within the meaning of Section 368(a) of the Code, then a U.S. Holder that exchanges its Existing Benson Hill Common Stock for New Benson Hill Common Stock would recognize any gain in connection with the merger and may be subject to substantial U.S. federal income taxes. For more information on the material U.S. federal income tax consequences of the merger to U.S. Holders of Existing Benson Hill Common Stock, see “Material U.S. Federal Income Tax Consequences — Tax Consequences to U.S. Holders — Tax Consequences of the Merger to U.S. Holders of Existing Benson Hill Common Stock.’’

The Sponsor has agreed to vote in favor of the proposals at the STPC Special Meeting, regardless of how public stockholders vote.

As of the date hereof, the Founder Shares owned by STPC’s Sponsors represent approximately 20% of the voting power of the outstanding STPC common stock. Pursuant to the Sponsor Support Agreement, the Sponsor has agreed to vote its Founder Shares and any shares of Class A Common Stock held by it in favor of each of the proposals at the STPC Special Meeting, regardless of how public stockholders vote. Accordingly, the agreement by the Sponsor to vote in favor of each of the proposals at the STPC Special Meeting will increase the likelihood that STPC will receive the requisite stockholder approval for the merger and the transactions contemplated thereby.

Because of STPC’s limited resources and the significant competition for business combination opportunities, if the merger is not consummated, it may be more difficult for it to complete an initial business combination. If STPC is unable to complete an initial business combination, its public stockholders may receive only approximately $10.00 per share on its redemption of its shares of Class A Common Stock, or less than such amount in certain circumstances, based on the balance of its Trust Account (as of June 30, 2021), and its warrants will expire worthless.

If the merger is not consummated, STPC will continue looking for business combination opportunities. STPC encounters competition from other entities having a business objective similar to its own, including private investors (which may be individuals or investment partnerships), other blank check companies and other entities competing for the types of businesses it intends to acquire. Many of these individuals and entities are well-established and have extensive experience in identifying and effecting, directly or indirectly, acquisitions of companies operating in or providing services to various industries. Many of these competitors possess similar technical, human and other resources to those of STPC, and its financial resources will be relatively limited when contrasted with those of many of these competitors. While STPC believes there are numerous target businesses it could potentially acquire with the net proceeds of its IPO and the sale of the Private Placement Warrants if the merger is not consummated, STPC’s ability to compete with respect to the acquisition of certain target businesses that are sizable will be limited by its available financial resources. This inherent competitive limitation gives others an advantage in pursuing the acquisition of certain target businesses.

Furthermore, because STPC is obligated to pay cash for the shares of Class A Common Stock its public stockholders redeem in connection with an initial business combination, target companies will be aware that this may reduce the resources available to STPC for the initial business combination. This may place STPC at a competitive disadvantage in successfully negotiating an initial business combination. If it is unable to complete an initial business combination, STPC’s public stockholders may only receive $10.00

46

per share on the liquidation of its Trust Account, based on the balance of the Trust Account (as of June 30, 2021), and its warrants will expire worthless.

STPC may not be able to consummate the merger or an initial business combination within the required time period, in which case it would cease all operations except for the purpose of winding up and it would redeem the Class A Common Stock and liquidate, in which case the holders of Class A Common Stock may only receive $10.00 per share, or less than such amount in certain circumstances, and the public warrants will expire worthless.

The Existing Charter provides that STPC must complete an initial business combination by January 8, 2023. If STPC is unable to consummate the merger or complete another initial business combination before January 8, 2023, STPC will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten (10) business days thereafter, redeem the Class A Common Stock, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to STPC to pay its taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding shares of Class A Common Stock, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining stockholders and STPC’s board of directors, dissolve and liquidate, subject in each case to STPC’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to its warrants, which will expire worthless if STPC fails to complete an initial business combination within the 24 month time period. In certain circumstances, the holders of Class A Common Stock may receive less than $10.00 per share on the redemption of their shares.

STPC’s Sponsor, directors, officers, advisors and their affiliates may elect to purchase shares or warrants from holders of Class A Common Stock, which may influence the vote on the Business Combination Proposal and reduce the public float of the Class A Common Stock.

STPC’s Sponsor, directors, officers, advisors or their affiliates may purchase Class A Common Stock or public warrants or a combination thereof in privately negotiated transactions or in the open market either prior to or following the consummation of the merger and the other transactions contemplated by the merger agreement, although they are under no obligation to do so. However, they have no current commitments, plans or intentions to engage in such transactions and have not formulated any terms or conditions for any such transactions. None of the funds in the Trust Account will be used to purchase Class A Common Stock or public warrants in such transactions.

Such a purchase may include a contractual acknowledgement that such stockholder, although still the record holder of Class A Common Stock is no longer the beneficial owner thereof and therefore agrees not to exercise its redemption rights. In the event that STPC’s Sponsor, directors, officers, advisors or their affiliates purchase shares in privately negotiated transactions from holders of Class A Common Stock who have already elected to exercise their redemption rights, such selling stockholders would be required to revoke their prior elections to redeem their shares. The purpose of such purchases could be to vote such shares in favor of the Business Combination Proposal and thereby increase the likelihood of obtaining stockholder approval of the Business Combination Proposal. The purpose of any such purchases of public warrants could be to reduce the number of public warrants outstanding or to vote such warrants on any matters submitted to the warrantholders for approval in connection with the merger or the other transactions contemplated by the merger agreement. Any such purchases of STPC securities may result in consummation of the merger, which may not otherwise have been possible. Any such purchases will be reported pursuant to Sections 13 and 16 of the Exchange Act to the extent such purchasers are subject to such reporting requirements.

In addition, if such purchases are made, the public float of Class A Common Stock or public warrants and the number of beneficial holders of STPC securities may be reduced, possibly making it difficult to maintain the quotation, listing or trading of STPC securities on a national securities exchange.

47

Neither STPC nor its stockholders will have the protection of any indemnification, escrow, price adjustment or other provisions that allow for a post-closing adjustment to be made to the total merger consideration in the event that any of the representations and warranties made by Benson Hill in the merger agreement ultimately proves to be inaccurate or incorrect.

The representations and warranties made by Benson Hill and STPC to each other in the merger agreement will not survive the consummation of the merger. As a result, STPC and its stockholders will not have the protection of any indemnification, escrow, price adjustment or other provisions that allow for a post-closing adjustment to be made to the total merger consideration if any representation or warranty made by Benson Hill in the merger agreement proves to be inaccurate or incorrect. Accordingly, to the extent such representations or warranties are incorrect, STPC would have no indemnification claim with respect thereto and its financial condition or results of operations could be adversely affected.

Either STPC or Benson Hill may waive one or more of the conditions to the merger or certain of the other transactions contemplated by the merger agreement.

Either STPC or Benson Hill may agree to waive, in whole or in part, some of the conditions to our obligations to consummate the merger or certain of the other transaction contemplated by the merger agreement, to the extent permitted by the Existing Charter and applicable laws. For example, it is a condition to our obligations to consummate the merger that certain of Benson Hill’s representations and warranties are true and correct in all respects as of the closing, except where the failure of such representations and warranties to be true and correct, taken as a whole, would not result in a material adverse effect. However, if STPC’s board of directors determines that it is in the best interest of the STPC stockholders to waive any such breach, then the board may elect to waive that condition and consummate the merger. No party is able to waive the condition that STPC stockholders approve the Business Combination Proposal.

STPC does not have a specified maximum redemption threshold. The absence of such a redemption threshold may make it possible for STPC to consummate an initial business combination with which a substantial majority of STPC’s stockholders do not agree.

The Existing Charter does not provide a specified maximum redemption threshold, except that in no event will STPC redeem the Class A Common Stock in an amount that would cause its net tangible assets to be less than $5,000,001 upon consummation of an initial business combination and after payment of underwriters’ fees and commissions (such that STPC is not subject to the SEC’s “penny stock” rules). As a result, STPC may be able to consummate the merger even if a substantial majority of its stockholders do not agree with the merger and have redeemed their shares. Though STPC does not expect such a result in connection with the merger, in the event the aggregate cash consideration STPC would be required to pay for all shares of Class A Common Stock that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the merger agreement exceed the aggregate amount of cash available to STPC, STPC will not complete the merger or redeem any shares, all shares of Class A Common Stock submitted for redemption will be returned to the holders thereof, and STPC instead may search for an alternate business combination.

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

STPC’s placing of funds in the Trust Account may not protect those funds from third-party claims against STPC. Although STPC has sought to have all vendors, service providers, prospective target businesses and other entities with which it does business (except its independent registered accounting firm) execute agreements with STPC waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of the holders of Class A Common Stock, such parties may not execute such agreements, or even if they execute such agreements they may not be prevented from bringing claims against the Trust Account, including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against STPC’s assets, including the funds held in the Trust Account. If any third-party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, STPC’s management will perform an analysis of the alternatives available to it and will

48

only enter into an agreement with a third-party that has not executed a waiver if management believes that such third-party’s engagement would be significantly more beneficial to STPC than any alternative. STPC is not aware of any product or service providers who have not or will not provide such waiver other than the underwriters of its IPO and STPC’s independent registered public accounting firm.

STPC’s directors may decide not to enforce the indemnification obligations of the Sponsor, resulting in a reduction in the amount of funds in the Trust Account available for distribution to the holders of Class A Common Stock.

In the event that the proceeds in the Trust Account are reduced below the lesser of (i) $10.00 per public share and (ii) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, and the Sponsor asserts that it is unable to satisfy its obligations or that it has no indemnification obligations related to a particular claim, STPC’s independent directors would determine whether to take legal action against the Sponsor to enforce its indemnification obligations.

While STPC currently expects that its independent directors would take legal action on its behalf against the Sponsor to enforce its indemnification obligations to STPC, it is possible that STPC’s independent directors in exercising their business judgment and subject to their fiduciary duties may choose not to do so in any particular instance if, for example, the cost of such legal action is deemed by the independent directors to be too high relative to the amount recoverable or if the independent directors determine that a favorable outcome is not likely. If STPC’s independent directors choose not to enforce these indemnification obligations, the amount of funds in the Trust Account available for distribution to the holders of Class A Common Stock may be reduced below $10.00 per share.

STPC may not have sufficient funds to satisfy indemnification claims of its directors and executive officers.

STPC has agreed to indemnify its officers and directors to the fullest extent permitted by law. However, STPC’s officers and directors have agreed to waive any right, title, interest or claim of any kind in or to any monies in the Trust Account and not to seek recourse against the Trust Account for any reason whatsoever. Accordingly, any indemnification provided will be able to be satisfied by STPC only if (i) STPC has sufficient funds outside of the Trust Account or (ii) STPC consummates an initial business combination. STPC’s obligation to indemnify its officers and directors may discourage stockholders from bringing a lawsuit against its officers or directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against STPC’s officers and directors, even though such an action, if successful, might otherwise benefit STPC and its stockholders. Furthermore, a stockholder’s investment may be adversely affected to the extent STPC pays the costs of settlement and damage awards against its officers and directors pursuant to these indemnification provisions.

If, after STPC distributes the proceeds in the Trust Account to the holders of Class A Common Stock, it files a bankruptcy petition or an involuntary bankruptcy petition is filed against STPC that is not dismissed, a bankruptcy court may seek to recover such proceeds, and STPC and its board may be exposed to claims of punitive damages.

If, after STPC distributes the proceeds in the Trust Account to its stockholders, it files a bankruptcy petition or an involuntary bankruptcy petition is filed against STPC that is not dismissed, any distributions received by STPC’s stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover all amounts received by STPC’s stockholders. In addition, the STPC board may be viewed as having breached its fiduciary duty to its creditors and/or having acted in bad faith, thereby exposing itself and STPC to claims of punitive damages, by paying STPC’s stockholders from the Trust Account prior to addressing the claims of creditors.

49

If, before distributing the proceeds in the Trust Account to the holders of Class A Common Stock, STPC files a bankruptcy petition or an involuntary bankruptcy petition is filed against STPC that is not dismissed, the claims of creditors in such proceeding may have priority over the claims of STPC’s stockholders and the per-share amount that would otherwise be received by STPC’s stockholders in connection with STPC’s liquidation may be reduced.

If, before distributing the proceeds in the Trust Account to the holders of Class A Common Stock, STPC files a bankruptcy petition or an involuntary bankruptcy petition is filed against STPC that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in STPC’s bankruptcy estate and subject to the claims of third parties with priority over the claims of STPC’s stockholders. To the extent any bankruptcy claims deplete the Trust Account, the per-share amount that would otherwise be received by STPC’s stockholders in connection with STPC’s liquidation may be reduced.

STPC stockholders may be held liable for claims by third parties against STPC to the extent of distributions received by them upon redemption of their shares.

Under the General Corporation Law of the State of Delaware (the “DGCL”), stockholders may be held liable for claims by third parties against a corporation to the extent of distributions received by them in a dissolution. The pro rata portion of the Trust Account distributed to the holders of Class A Common Stock upon the redemption of the Class A Common Stock in the event STPC does not complete an initial business combination within the timeframe set forth in the Existing Charter may be considered a liquidating distribution under Delaware law. If a corporation complies with certain procedures set forth in Section 280 of the DGCL intended to ensure that it makes reasonable provision for all claims against it, including a 60-day notice period during which any third-party claims can be brought against the corporation, a 90-day period during which the corporation may reject any claims brought, and an additional 150-day waiting period before any liquidating distributions are made to stockholders, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would be barred after the third anniversary of the dissolution. However, it is STPC’s intention to redeem the Class A Common Stock as soon as reasonably possible in the event it does not complete its initial business combination and, therefore, STPC does not intend to comply with the foregoing procedures.

Because STPC will not comply with Section 280, Section 281(b) of the DGCL requires STPC to adopt a plan, based on facts known to STPC at such time that will provide for STPC’s payment of all existing and pending claims or claims that may be potentially brought against STPC within the ten (10) years following its dissolution. However, because STPC is a blank check company, rather than an operating company, and STPC’s operations are limited to searching for prospective target businesses to acquire, the only likely claims to arise would be from STPC’s vendors (such as lawyers, investment bankers, etc.) or prospective target businesses. If STPC’s plan of distribution complies with Section 281(b) of the DGCL, any liability of stockholders with respect to a liquidating distribution is limited to the lesser of such stockholder’s pro rata share of the claim or the amount distributed to the stockholder, and any liability of the stockholder would likely be barred after the third anniversary of the dissolution. STPC cannot assure you that it will properly assess all claims that may be potentially brought against it. As such, STPC’s stockholders could potentially be liable for any claims to the extent of distributions received by them (but no more) and any liability of STPC’s stockholders may extend beyond the third anniversary of such date. Furthermore, if the pro rata portion of the Trust Account distributed to the holders of Class A Common Stock upon the redemption of the Class A Common Stock in the event STPC does not complete an initial business combination within the timeframe set forth in the Existing Charter is not considered a liquidating distribution under Delaware law and such redemption distribution is deemed to be unlawful (potentially due to the imposition of legal proceedings that a party may bring or due to other circumstances that are currently unknown), then pursuant to Section 174 of the DGCL, the statute of limitations for claims of creditors could then be six (6) years after the unlawful redemption distribution, instead of three (3) years, as in the case of a liquidating distribution.

STPC may not be able to complete the PIPE Investment in connection with the merger.

STPC may not be able to complete the PIPE Investment on terms that are acceptable to STPC, or at all. If STPC does not complete the PIPE Investment, STPC may not be able to consummate the merger or

50

certain other transactions contemplated by the merger agreement. The terms of any alternative financing may be more onerous to the combined company than the PIPE Investment, and STPC may be unable to obtain alternative financing on terms that are acceptable to it, or at all. The failure to secure additional financing could have a material adverse effect on the continued development or growth of the combined company.

None of STPC’s officers, directors or stockholders is required to provide any financing to STPC in connection with or after the consummation of the merger.

STPC may amend the terms of its warrants in a manner that may be adverse to holders of public warrants with the approval by the holders of at least 65% of the then-outstanding warrants. As a result, the exercise price of the warrants could be increased, the exercise period could be shortened and the number of shares of Class A Common Stock purchasable upon exercise of a public warrant could be decreased, all without your approval.

The STPC Warrants were issued in registered form under the Warrant Agreement (as defined herein) between CST, as warrant agent, and STPC. The Warrant Agreement provides that the terms of STPC’s warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 65% of the then-outstanding warrants to make any change that adversely affects the interests of the registered holders of the public warrants. Accordingly, STPC may amend the terms of the public warrants in a manner adverse to a holder if holders of at least 65% of the then-outstanding warrants approve of such amendment.

Although STPC’s ability to amend the terms of the public warrants with the consent of at least 65% of the then-outstanding warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the warrants, convert the warrants into cash or stock, shorten the exercise period or decrease the number of shares of Class A Common Stock purchasable upon exercise of a warrant.

STPC may redeem your unexpired warrants prior to their exercise at a time that is disadvantageous to you, thereby making your warrants worthless.

STPC has the ability to redeem outstanding warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per warrant, provided that the last reported sales price of Class A Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any twenty (20) trading days within a thirty (30) trading-day period commencing once the warrants become exercisable and ending on the third trading day prior to the date on which STPC gives proper notice of such redemption and provided certain other conditions are met. If and when the warrants become redeemable by STPC, STPC may not exercise its redemption right if the issuance of shares of common stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or it is unable to effect such registration or qualification. STPC will use its best efforts to register or qualify such shares of common stock under the blue sky laws of the state of residence in those states in which the warrants were offered. Redemption of the outstanding warrants could force you (i) to exercise your warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (ii) to sell your warrants at the then-current market price when you might otherwise wish to hold your warrants or (iii) to accept the nominal redemption price which, at the time the outstanding warrants are called for redemption, is likely to be substantially less than the market value of your warrants. None of the Private Placement Warrants will be redeemable by STPC so long as they are held by the Sponsor or its permitted transferees.

Subsequent to the consummation of the merger and the other transactions contemplated by the merger agreement, New Benson Hill may be required to take write-downs or write-offs, or the combined company may be subject to restructuring, impairment or other charges that could have a significant negative effect on the combined company’s financial condition, results of operations and the price of New Benson Hill Common Stock, which could cause you to lose some or all of your investment.

Although STPC has conducted due diligence on Benson Hill, this diligence may not reveal all material issues that may be present with Benson Hill’s business. Factors outside of Benson Hill’s and STPC’s respective control may, at any time, arise. As a result of these factors, New Benson Hill may be forced to later

51

write-down or write-off assets, restructure operations, or incur impairment or other charges that could result in the combined company reporting losses. Even if STPC’s due diligence successfully identified certain risks, unexpected risks may arise and previously known risks may materialize in a manner not consistent with STPC’s preliminary risk analysis. Even though these charges may be non-cash items and therefore not have an immediate impact on the combined company’s liquidity, the fact that the combined company reports charges of this nature could contribute to negative market perceptions about the combined company or its securities. In addition, charges of this nature may cause the combined company to be unable to obtain future financing on favorable terms or at all.

New Benson Hill’s failure to timely and effectively implement controls and procedures required by Section 404(a) of the Sarbanes-Oxley Act that will be applicable to it after the merger is consummated could have a material adverse effect on its business.

Benson Hill is currently not subject to Section 404 of the Sarbanes-Oxley Act. However, following the consummation of the merger and the other transactions contemplated by the merger agreement, the combined company will be required to provide management’s attestation on internal controls commencing with New Benson Hill’s annual report for the year ending December 31, 2021 in accordance with applicable SEC guidance. The standards required for a public company under Section 404(a) of the Sarbanes-Oxley Act are significantly more stringent than those required of Benson Hill as a privately-held company. Management may not be able to effectively and timely implement controls and procedures that adequately respond to the increased regulatory compliance and reporting requirements that will be applicable after the merger. If the combined company is not able to implement the additional requirements of Section 404(a) in a timely manner or with adequate compliance, it may not be able to assess whether its internal controls over financial reporting are effective, which may subject it to adverse regulatory consequences and could harm investor confidence and the market price of its securities.

New Benson Hill will qualify as an “emerging growth company” within the meaning of the Securities Act, and if it takes advantage of certain exemptions from disclosure requirements available to emerging growth companies, it could make New Benson Hill’s securities less attractive to investors and may make it more difficult to compare New Benson Hill’s performance to the performance of other public companies.

New Benson Hill will qualify as an “emerging growth company” as defined in Section 2(a)(19) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As such, the combined company will be eligible for and intends to take advantage of certain exemptions from various reporting requirements applicable to other public companies that are not emerging growth companies for as long as it continues to be an emerging growth company, including, but not limited to, (a) not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act, (b) reduced disclosure obligations regarding executive compensation in New Benson Hill’s periodic reports and proxy statements and (c) exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. As a result, New Benson Hill’s stockholders may not have access to certain information they may deem important. New Benson Hill will remain an emerging growth company until the earliest of (1) the last day of the fiscal year (a) following January 8, 2026, (b) in which New Benson Hill has total annual gross revenue of at least $1.07 billion, or (c) in which New Benson Hill is deemed to be a large accelerated filer, which means the market value of its common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th subject to compliance with periodic reporting requirements for a period of at least twelve (12) months, and (2) the date on which New Benson Hill has issued more than $1.0 billion in non-convertible debt securities during the prior three (3) year period. STPC cannot predict whether investors will find New Benson Hill’s securities less attractive because it will rely on these exemptions. If some investors find the combined company’s securities less attractive as a result of the combined company’s reliance on these exemptions, the trading prices of the combined company’s securities may be lower than they otherwise would be, there may be a less active trading market for New Benson Hill’s securities and the trading prices of the combined company’s securities may be more volatile.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities

52

registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. STPC has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, it, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of STPC’s financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

The future exercise of registration rights may adversely affect the market price of New Benson Hill Common Stock.

Certain New Benson Hill stockholders will have registration rights for restricted securities. In connection with the consummation of the merger, New Benson Hill will enter into the IRA with STPC, the Sponsor and certain other stockholders of New Benson Hill, which will provide for customary “demand” and “piggyback” registration rights for certain stockholders that will own an aggregate of 99,790,758 shares of New Benson Hill Common Stock upon consummation of the merger, representing approximately 58.9% of the outstanding shares of New Benson Hill Common Stock assuming the maximum number of shares of STPC’s Class A Common Stock are redeemed in connection with the merger or approximately 47.6% of the outstanding shares of New Benson Hill Common Stock assuming no shares of STPC’s Class A Common Stock are redeemed in connection with the merger. Sales of a substantial number of shares of New Benson Hill Common Stock pursuant to the resale registration statement in the public market could occur at any time the registration statement remains effective. In addition, certain registration rights holders can request underwritten offerings to sell their securities. These sales, or the perception in the market that the holders of a large number of shares intend to sell shares, could reduce the market price of New Benson Hill Common Stock.

STPC Warrants will become exercisable for New Benson Hill Common Stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to New Benson Hill stockholders.

Outstanding STPC Warrants to purchase an aggregate of 16.6 million shares of New Benson Hill Common Stock will become exercisable on the later of thirty (30) days after the completion of the merger or twelve (12) months from the consummation of STPC’s IPO. Each warrant entitles the holder thereof to purchase one (1) share of New Benson Hill Common Stock at a price of $11.50 per whole share, subject to adjustment. STPC Warrants may be exercised only for a whole number of shares of New Benson Hill Common Stock. To the extent such warrants are exercised, additional shares of New Benson Hill Common Stock will be issued, which will result in dilution to the then existing holders of New Benson Hill Common Stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of New Benson Hill Common Stock.

STPC’s ability to successfully effect the merger and the other transactions contemplated by the merger agreement and New Benson Hill’s ability to successfully operate the business thereafter will be largely dependent upon the efforts of certain key personnel of Benson Hill, all of whom STPC expects to stay with the combined company following the consummation of the merger. Any loss of such key personnel could negatively impact the operations and financial results of the combined business.

STPC’s ability to successfully effect the merger and the other transactions contemplated by the merger agreement and New Benson Hill’s ability to successfully operate the business following the consummation of the merger is dependent upon the efforts of certain key personnel of Benson Hill. Although STPC expects key personnel to remain with the combined company following the consummation of the merger, there can be no assurance that they will do so. It is possible that Benson Hill will lose some key personnel, the loss of which could negatively impact the operations and profitability of the combined company. Furthermore, following the consummation of the merger, certain of the key personnel of Benson Hill may be unfamiliar

53

with the requirements of operating a company regulated by the SEC, which could cause the combined company to have to expend time and resources helping them become familiar with such requirements.

The Existing Charter requires, to the fullest extent permitted by law, that derivative actions brought in STPC’s name, actions against STPC’s directors, officers, other employees or stockholders for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel, which may have the effect of discouraging lawsuits against STPC’s directors, officers, other employees or stockholders.

The Existing Charter requires, to the fullest extent permitted by law, that derivative actions brought in STPC’s name, actions against STPC’s directors, officers, other employees or stockholders for breach of fiduciary duty and other similar actions may be brought only in the Court of Chancery in the State of Delaware and, if brought outside of Delaware, the stockholder bringing the suit will be deemed to have consented to service of process on such stockholder’s counsel except any action (A) as to which the Court of Chancery in the State of Delaware determines that there is an indispensable party not subject to the jurisdiction of the Court of Chancery (and the indispensable party does not consent to the personal jurisdiction of the Court of Chancery within ten (10) days following such determination), (B) which is vested in the exclusive jurisdiction of a court or forum other than the Court of Chancery, (C) for which the Court of Chancery does not have subject matter jurisdiction, or (D) any action arising under the Securities Act, as to which the Court of Chancery and the federal district court for the District of Delaware will have concurrent jurisdiction. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock will be deemed to have notice of and consented to the forum provisions in our Existing Charter. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with STPC or any of its directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims, although such stockholders will not be deemed to have waived STPC’s compliance with federal securities laws and the rules and regulations thereunder. However, there is no assurance that a court would enforce the choice of forum provision contained in the Existing Charter. If a court were to find such provision to be inapplicable or unenforceable in an action, STPC may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition.

The Existing Charter provides that the exclusive forum provision will be applicable to the fullest extent permitted by applicable law. Section 27 of the Exchange Act creates exclusive federal jurisdiction over all suits brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. As a result, the exclusive forum provision will not apply to suits brought to enforce any duty or liability created by the Exchange Act or any other claim for which the federal courts have exclusive jurisdiction.

Additional Risks Relating to Ownership of New Benson Hill Common Stock Following the Merger

The NYSE may delist New Benson Hill’s securities from trading on its exchange, which could limit investors’ ability to make transactions in its securities and subject New Benson Hill to additional trading restrictions.

Currently, STPC’s units, Class A Common Stock and public warrants are publicly traded on the NYSE. We intend to list the combined company’s common stock and public warrants on the NYSE under the symbols BHIL and BHIL WS, respectively, upon the closing of the merger. STPC will not have units traded following closing of the merger. STPC cannot assure you that its securities will continue to be listed on the NYSE following the merger. In order to continue listing its securities on the NYSE following the merger, New Benson Hill will be required to maintain certain financial, distribution and stock price levels. Generally, New Benson Hill will be required to maintain a minimum market capitalization (generally $50,000,000) and a minimum number of holders of our securities (generally 300 public holders). Additionally, in connection with the merger, New Benson Hill will be required to demonstrate compliance with NYSE’s initial listing requirements, which are more rigorous than NYSE’s continued listing requirements, in order to continue to maintain the listing of its securities on the NYSE. For instance, New Benson Hill’s stock price would generally be required to be at least $4.00 per share and New Benson Hill’s market capitalization would generally be required to be at least $150,000,000. In addition to the listing requirements for the New

54

Benson Hill Common Stock, the NYSE imposes listing standards on warrants. We cannot assure you that New Benson Hill will be able to meet those initial listing requirements at that time.

If NYSE delists New Benson Hill’s securities from trading on its exchange and New Benson Hill is not able to list its securities on another national securities exchange, we expect our securities could be quoted on an over-the-counter market. If this were to occur, we could face significant material adverse consequences, including:

•

a limited availability of market quotations for our securities;

•

reduced liquidity for our securities;

•

a determination that the New Benson Hill Common Stock is a “penny stock” which will require brokers trading in New Benson Hill Common Stock to adhere to more stringent rules and possibly result in a reduced level of trading activity in the secondary trading market for our securities;

•

a limited amount of news and analyst coverage; and

•

a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Since STPC’s units, Class A Common Stock and public warrants are listed on the NYSE, they are covered securities. Although the states are preempted from regulating the sale of its securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. While STPC is not aware of a state having used these powers to prohibit or restrict the sale of securities issued by blank check companies, other than the State of Idaho, certain state securities regulators view blank check companies unfavorably and might use these powers, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if STPC was no longer listed on the NYSE, its securities would not be covered securities and it would be subject to regulation in each state in which it offers its securities, including in connection with the initial business combination.

The SPTC Warrants are accounted for as liabilities and the changes in value of such warrants could have a material effect on New Benson Hill’s financial results following the merger.

On April 12, 2021, the Acting Director of the Division of Corporation Finance and Acting Chief Accountant of the SEC together issued a statement regarding the accounting and reporting considerations for warrants issued by special purpose acquisition companies entitled “Staff Statement on Accounting and Reporting Considerations for Warrants Issued by Special Purpose Acquisition Companies (‘SPACs’)” ​(the “SEC Statement”). Specifically, the SEC Statement focused on certain settlement terms and provisions related to certain tender offers following a business combination, which terms are similar to those contained in the warrant agreement governing the STPC Warrants.

As a result of the SEC Statement, STPC reevaluated the accounting treatment of its public warrants and Private Placement Warrants, and determined to classify the warrants as derivative liabilities measured at fair value, with changes in fair value each period reported in earnings. STPC conducted a valuation of its warrants and restated its previously issued post-IPO balance sheet dated as of January 8, 2021 and related notes and included on such balance sheet are derivative liabilities related to embedded features contained within the STPC Warrants. Accounting Standards Codification 815, Derivatives and Hedging, provides for the remeasurement of the fair value of such derivatives at each balance sheet date, with a resulting non-cash gain or loss related to the change in the fair value being recognized in earnings in the statement of operations. Following the merger, New Benson Hill’s consolidated financial statements and results of operations may fluctuate quarterly, as a result of the recurring fair value measurement of the STPC Warrants, based on factors which are outside of New Benson Hill’s control. Due to the recurring fair value measurement, New Benson Hill may recognize non-cash gains or losses on the STPC Warrants each reporting period and that the amount of such gains or losses could be material. The impact of changes in fair value on earnings may have an adverse effect on the market price of New Benson Hill’s securities.

55

New Benson Hill’s stock price may change significantly following the merger and you could lose all or part of your investment as a result.

The trading price of the New Benson Hill Common Stock is likely to be volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares at an attractive price due to a number of factors such as those listed in “— Risks Relating to Benson Hill’s Business and Industry” and the following:

•

results of operations that vary from the expectations of securities analysts and investors;

•

results of operations that vary from those of New Benson Hill’s competitors;

•

the impact of the COVID-19 pandemic and its effect on New Benson Hill’s business and financial conditions;

•

changes in expectations as to New Benson Hill’s future financial performance, including financial estimates and investment recommendations by securities analysts and investors;

•

declines in the market prices of stocks generally;

•

strategic actions by New Benson Hill or its competitors;

•

announcements by New Benson Hill or its competitors of significant contracts, acquisitions, joint ventures, other strategic relationships or capital commitments;

•

any significant change in New Benson Hill’s management;

•

changes in general economic or market conditions or trends in New Benson Hill’s industry or markets;

•

changes in business or regulatory conditions, including new laws or regulations or new interpretations of existing laws or regulations applicable to New Benson Hill’s business;

•

future sales of New Benson Hill Common Stock or other securities;

•

investor perceptions or the investment opportunity associated with New Benson Hill Common Stock relative to other investment alternatives;

•

the public’s response to press releases or other public announcements by New Benson Hill or third parties, including New Benson Hill’s filings with the SEC;

•

litigation involving New Benson Hill, New Benson Hill’s industry, or both, or investigations by regulators into New Benson Hill’s operations or those of New Benson Hill’s competitors;

•

guidance, if any, that New Benson Hill provides to the public, any changes in this guidance or New Benson Hill’s failure to meet this guidance;

•

the development and sustainability of an active trading market for New Benson Hill’s stock;

•

actions by institutional or activist stockholders;

•

changes in accounting standards, policies, guidelines, interpretations or principles; and

•

other events or factors, including those resulting from natural disasters, war, acts of terrorism or responses to these events.

These broad market and industry fluctuations may adversely affect the market price of New Benson Hill Common Stock, regardless of New Benson Hill’s actual operating performance. In addition, price volatility may be greater if the public float and trading volume of New Benson Hill Common Stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If New Benson Hill was involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from New Benson Hill’s business regardless of the outcome of such litigation.

56

Because there are no current plans to pay cash dividends on New Benson Hill Common Stock for the foreseeable future, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

New Benson Hill intends to retain future earnings, if any, for future operations, expansion and debt repayment and there are no current plans to pay any cash dividends for the foreseeable future. The declaration, amount and payment of any future dividends on shares of New Benson Hill Common Stock will be at the sole discretion of New Benson Hill’s board of directors. New Benson Hill’s board of directors may take into account general and economic conditions, New Benson Hill’s financial condition and results of operations, New Benson Hill’s available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax, and regulatory restrictions, implications on the payment of dividends by New Benson Hill to its stockholders or by its subsidiaries to it and such other factors as New Benson Hill’s board of directors may deem relevant. In addition, New Benson Hill’s ability to pay dividends is limited by covenants of Benson Hill’s existing and outstanding indebtedness and may be limited by covenants of any future indebtedness New Benson Hill incurs. As a result, you may not receive any return on an investment in New Benson Hill Common Stock unless you sell New Benson Hill Common Stock for a price greater than that which you paid for it.

If securities analysts do not publish research or reports about New Benson Hill’s business or if they downgrade New Benson Hill’s stock or New Benson Hill’s sector, New Benson Hill’s stock price and trading volume could decline.

The trading market for New Benson Hill Common Stock will rely in part on the research and reports that industry or financial analysts publish about New Benson Hill or its business. New Benson Hill will not control these analysts. In addition, some financial analysts may have limited expertise with Benson Hill’s model and operations. Furthermore, if one or more of the analysts who do cover New Benson Hill downgrade its stock or industry, or the stock of any of its competitors, or publish inaccurate or unfavorable research about its business, the price of New Benson Hill’s stock could decline. If one or more of these analysts ceases coverage of New Benson Hill or fails to publish reports on it regularly, New Benson Hill could lose visibility in the market, which in turn could cause its stock price or trading volume to decline.

Future sales, or the perception of future sales, by New Benson Hill or its stockholders in the public market following the merger could cause the market price for New Benson Hill Common Stock to decline.

The sale of shares of New Benson Hill Common Stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of New Benson Hill Common Stock. These sales, or the possibility that these sales may occur, also might make it more difficult for New Benson Hill to sell equity securities in the future at a time and at a price that it deems appropriate.

Upon consummation of the merger, using the value of the Trust Account as of June 30, 2021, and subject to the assumptions set forth in “Basis of Presentation and Glossary,” New Benson Hill would have a total of approximately 209.7 million shares of common stock (assuming no redemptions) outstanding. All shares issued in the merger will be freely tradable without registration under the Securities Act and without restriction by persons other than New Benson Hill’s “affiliates” ​(as defined under Rule 144 of the Securities Act, “Rule 144”), including New Benson Hill’s directors, executive officers and other affiliates.

In connection with the merger, certain substantial holders of Benson Hill’s common stock (determined on an as-converted basis) (the “New Holders”) have agreed with STPC, subject to certain exceptions, (i) not to transfer or dispose of their New Benson Hill Common Stock until (x) the earlier of six (6) months after the consummation of the merger and (y) the date after the closing on which New Benson Hill completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of New Benson Hill’s stockholders having the right to exchange their equity holdings in New Benson Hill for cash, securities or other property, and (ii) not engage, directly or indirectly, in any short sales or other hedging or derivative transactions involving STPC’s common stock or warrants beginning on the date that the merger agreement is executed and ended six (6) months after the consummation of the merger. In addition, STPC’s current officers and directors and their affiliates, New Benson Hill’s Chief Executive Officer and Chairman (together with the New Holders, the “Investors”) have agreed with STPC, subject to certain exceptions, not to transfer or dispose of their New Benson Hill Common Stock during the period from the

57

date of the closing of the merger through the earlier of (i) the first anniversary of the consummation of merger, (ii) the date that the closing price of the New Benson Hill Common Stock equals or exceeds $12.00 (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like), for twenty (20) trading days within any thirty (30) trading day period following the 150th day following the merger and (iii) the consummation of a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of New Benson Hill’s stockholders having the right to exchange their shares of New Benson Hill Common Stock for cash, securities or other property.

Upon the expiration or waiver of the lock-ups described above, shares held by the Investors and certain other stockholders of New Benson Hill will be eligible for resale, subject to volume, manner of sale and other limitations under Rule 144, when such rule becomes applicable to STPC. In addition, pursuant to the IRA, the Investors and certain other stockholders will have the right, subject to certain conditions, to require New Benson Hill to register the sale of their shares of New Benson Hill Common Stock under the Securities Act. By exercising their registration rights and selling a large number of shares, these stockholders could cause the prevailing market price of New Benson Hill Common Stock to decline. Following completion of the merger, the shares covered by registration rights (including in respect of the shares issued in connection with the PIPE Investment) will represent approximately       % of the then-outstanding New Benson Hill Common Stock.

As restrictions on resale end or if these stockholders exercise their registration rights, the market price of shares of New Benson Hill Common Stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for New Benson Hill to raise additional funds through future offerings of New Benson Hill’s shares of Class A Common Stock or other securities.

In addition, the shares of New Benson Hill Common Stock reserved for future issuance under New Benson Hill’s equity incentive plans will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements, lock-up agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. The number of shares of New Benson Hill Common Stock expected to be reserved for future issuance under its equity incentive plans is equal to       % of the aggregate number of shares of New Benson Hill Common Stock outstanding at closing, reduced by the number of shares of STPC common stock, if any, that are subject to STPC options. The compensation committee of New Benson Hill’s board of directors may determine the exact number of shares to be reserved for future issuance under its equity incentive plans at its discretion. New Benson Hill is expected to file one or more registration statements on Form S-8 under the Securities Act to register shares of New Benson Hill Common Stock or securities convertible into or exchangeable for shares of New Benson Hill Common Stock issued pursuant to New Benson Hill’s equity incentive plans. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

In the future, New Benson Hill may also issue its securities in connection with investments or acquisitions. The amount of shares of New Benson Hill Common Stock issued in connection with an investment or acquisition could constitute a material portion of New Benson Hill’s then-outstanding shares of common stock. Any issuance of additional securities in connection with investments or acquisitions may result in additional dilution to New Benson Hill’s stockholders.

Anti-takeover provisions in New Benson Hill’s organizational documents could delay or prevent a change of control.

Certain provisions of New Benson Hill’s second amended and restated certificate of incorporation and amended and restated bylaws to become effective upon the consummation of the merger may have an anti-takeover effect and may delay, defer or prevent a merger, acquisition, tender offer, takeover attempt or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by New Benson Hill’s stockholders.

These provisions, among other things:

58

•

authorize New Benson Hill’s board of directors to issue new series of preferred stock without stockholder approval and create, subject to applicable law, a series of preferred stock with preferential rights to dividends or our assets upon liquidation, or with superior voting rights to our existing common stock;

•

eliminate the ability of stockholders to call special meetings of stockholders;

•

eliminate the ability of stockholders to fill vacancies on New Benson Hill’s board of directors;

•

establish advance notice requirements for nominations for election to New Benson Hill’s board of directors or for proposing matters that can be acted upon by stockholders at our annual stockholder meetings;

•

permit New Benson Hill’s board of directors to establish the number of directors, provided that the board must consist of at least five and no more than fifteen directors;

•

provide that New Benson Hill’s board of directors is expressly authorized to make, alter or repeal New Benson Hill’s amended and restated bylaws;

•

require, prior to            , 2024, the affirmative vote of at least 662∕3% of the voting power of the outstanding shares of capital stock entitled to vote thereon, voting together as a single class, to amend New Benson Hill’s amended and restated bylaws and specific provisions of New Benson Hill’s second amended and restated certificate of incorporation; and

•

limit the jurisdictions in which certain stockholder litigation may be brought.

As a Delaware corporation, New Benson Hill will be subject to the anti-takeover provisions of Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in a business combination specified in the statute with an interested stockholder (as defined in the statute) for a period of three (3) years after the date of the transaction in which the person first becomes an interested stockholder, unless the business combination is approved in advance by a majority of the independent directors or by the holders of at least two-thirds of the outstanding disinterested shares. The application of Section 203 of the DGCL could also have the effect of delaying or preventing a change of control of our company.

These anti-takeover provisions could make it more difficult for a third-party to acquire New Benson Hill, even if the third-party’s offer may be considered beneficial by many of New Benson Hill’s stockholders. As a result, New Benson Hill’s stockholders may be limited in their ability to obtain a premium for their shares. These provisions could also discourage proxy contests and make it more difficult for you and other stockholders to elect directors of your choosing and to cause New Benson Hill to take other corporate actions you desire. See “Description of New Benson Hill Capital Stock” beginning on page 231.

New Benson Hill’s second amended and restated certificate of incorporation will designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by New Benson Hill’s stockholders, which could limit New Benson Hill’s stockholders’ ability to obtain a favorable judicial forum for disputes with New Benson Hill or its directors, officers, employees or stockholders.

New Benson Hill’s second amended and restated certificate of incorporation will provide that, unless New Benson Hill consents in writing to the selection of an alternative forum, the sole and exclusive forum, to the fullest extent permitted by law, for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (3) any action asserting a claim against us or any director, officer, or other employee arising pursuant to the DGCL, (4) any action to interpret, apply, enforce, or determine the validity of our second amended and restated certificate of incorporation or amended and restated bylaws, or (5) any other action asserting a claim that is governed by the internal affairs doctrine, shall be the Court of Chancery of the State of Delaware (or another state court or the federal court located within the State of Delaware if the Court of Chancery does not have or declines to accept jurisdiction), in all cases subject to the court’s having jurisdiction over indispensable parties named as defendants. In addition, New Benson Hill’s second amended and restated certificate of incorporation will provide that the federal district court for the District of Delaware (or, in the event such court does not have jurisdiction, the federal district courts of the United

59

States) will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act but that the forum selection provision will not apply to claims brought to enforce a duty or liability created by the Exchange Act. Although we believe these provisions benefit New Benson Hill by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers. Alternatively, if a court were to find the choice of forum provision contained in New Benson Hill’s second amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, financial condition, and operating results. For example, under the Securities Act, federal courts have concurrent jurisdiction over all suits brought to enforce any duty or liability created by the Securities Act, and investors cannot waive compliance with the federal securities laws and the rules and regulations thereunder. Any person or entity purchasing or otherwise acquiring any interest in our shares of capital stock shall be deemed to have notice of and consented to this exclusive forum provision, but will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder.

Certain of New Benson Hill’s stockholders, including the Sponsor, may engage in business activities which compete with New Benson Hill or otherwise conflict with New Benson Hill’s interests.

The Sponsor is in the business of making investments in companies and may from time to time acquire and hold interests in businesses that compete directly or indirectly with New Benson Hill. New Benson Hill’s second amended and restated certificate of incorporation will provide that none of the Sponsor, any of their respective affiliates or any director who is not employed by New Benson Hill (including any non-employee director who serves as one of New Benson Hill’s officers in both his director and officer capacities) or his or her affiliates will have any duty to refrain from engaging, directly or indirectly, in the same business activities or similar business activities or lines of business in which New Benson Hill operates. The Sponsor also may pursue acquisition opportunities that may be complementary to New Benson Hill’s business and, as a result, those acquisition opportunities may not be available to New Benson Hill.

Risks Relating to Redemption

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

No assurance can be given as to the price at which a public stockholder may be able to sell the shares of New Benson Hill Common Stock in the future following the completion of the merger. Certain events following the consummation of any business combination, including the merger, may cause an increase in New Benson Hill’s stock price, and may result in a lower value realized now than an STPC stockholder might realize in the future had the stockholder not elected to redeem such stockholder’s shares of Class A Common Stock. Similarly, if an STPC public stockholder does not redeem his, her or its shares, such stockholder will bear the risk of ownership of New Benson Hill Common Stock after the consummation of the merger, and there can be no assurance that a stockholder can sell his, her or its shares of New Benson Hill Common Stock in the future for a greater amount than the redemption price set forth in this proxy statement/prospectus. See ‘‘Questions and Answers — Questions and Answers About the STPC Special Meeting — How do redemptions affect the value of my New Benson Hill Common Stock?’’

Furthermore, all public warrants will remain outstanding after consummation of the merger even if all shares of Class A Common Stock are redeemed by STPC public stockholders. Based on the average of the high and low trading prices of the public warrants on the NYSE on June 18, 2021, the public warrants had an aggregate value of $15.1 million. However, there can be no assurance that the trading price of the public warrants or the shares of New Benson Hill Common Stock issuable upon exercise of the public warrants will increase due to redemptions of the Class A Common Stock. See “— Additional Risks Relating to Ownership of New Benson Hill Common Stock Following the Merger — New Benson Hill’s stock price may change significantly following the merger and you could lose all or part of your investment as a result.”

An STPC public stockholder should consult his, her or its own tax and/or financial advisor for assistance on how this may affect its individual situation.

60

If STPC public stockholders fail to comply with the redemption requirements specified in this proxy statement/prospectus, they will not be entitled to redeem their shares of Class A Common Stock for a pro rata portion of the funds held in the Trust Account.

To exercise their redemption rights, holders of Class A Common Stock are required to deliver their stock, either physically or electronically using Depository Trust Company’s DWAC System, to STPC’s transfer agent no later than 5:00 p.m., Eastern Time, on the second business day prior to the vote at the STPC Special Meeting. If a holder fails to properly seek redemption as described in this proxy statement/prospectus and the merger with Benson Hill is consummated, such holder will not be entitled to redeem these shares for a pro rata portion of funds deposited in the Trust Account. See the section entitled “STPC Special Meeting of Stockholders — Redemption Rights” for additional information on how to exercise your redemption rights.

If you or a “group” of stockholders of which you are a part are deemed to hold an aggregate of more than 15% of the shares of Class A Common Stock, you (or, if a member of such a group, all of the members of such group in the aggregate) will lose the ability to redeem all such shares in excess of 15% of the Class A Common Stock.

A public stockholder, together with any of his, her or its affiliates or any other person with whom it is acting in concert or as a “group” ​(as defined in Section 13(d)(3) of the Exchange Act), will be restricted from redeeming in the aggregate his, her or its shares of Class A Common Stock or, if part of such a group, the group’s Class A Common Stock, in excess of 15% of the shares of Class A Common Stock. Your inability to redeem any such excess shares of Class A Common Stock could resulting in you suffering a material loss on your investment in STPC if you sell such excess Class A Common Stock in open market transactions. STPC cannot assure you that the value of such excess Class A Common Stock will appreciate over time following the merger or that the market price of the Class A Common Stock will exceed the per-share redemption price.

There is uncertainty regarding the federal income tax consequences of the redemption to the holders of Class A Common Stock.

There is some uncertainty regarding the federal income tax consequences to holders of Class A Common Stock who exercise their redemption rights. The uncertainty of tax consequences relates primarily to the individual circumstances of the taxpayer and include (i) whether the redemption results in a dividend, taxable as ordinary income, or a sale, taxable as capital gain, and (ii) whether such capital gain is “long-term” or “short-term.” Whether the redemption qualifies for sale treatment, resulting in taxation as capital gain rather than ordinary income, will depend largely on whether the holder owns (or is deemed to own) any shares of Class A Common Stock following the redemption, and if so, the total number of shares of Class A Common Stock held by the holder both before and after the redemption relative to all shares of Class A Common Stock outstanding both before and after the redemption. The redemption generally will be treated as a sale, rather than a dividend, if the redemption (i) is “substantially disproportionate” with respect to the holder, (ii) results in a “complete termination” of the holder’s interest in STPC or (iii) is “not essentially equivalent to a dividend” with respect to the holder. Due to the personal and subjective nature of certain of such tests and the absence of clear guidance from the IRS, there is uncertainty as to whether a holder who elects to exercise its redemption rights will be taxed on any gain from the redemption as ordinary income or capital gain. See the section entitled “Material U.S. Federal Income Tax Consequences.”

UNAUDITED PRO FORMA COMBINED FINANCIAL INFORMATION

Introduction

STPC is providing the following unaudited pro forma condensed combined financial information to aid you in your analysis of the financial aspects of the merger and other transactions contemplated by the merger agreement, as more fully described below. The following unaudited pro forma condensed combined balance sheet of New Benson Hill as of June 30, 2021 and the unaudited pro forma condensed combined statements of operations of New Benson Hill for the six months ended June 30, 2021 and the year ended December 31, 2020 present the combination of the financial information of STPC and Benson Hill after giving effect to the following transactions:

•

the reverse recapitalization between Benson Hill and STPC pursuant to the merger,

•

the consummation of STPC’s IPO which occurred on January 8, 2021,

•

the Benson Hill Preferred Conversion,

•

the Debt Payoff, and

•

the issuance of an aggregate of 22.5 million shares of Class A Common Stock of STPC at a price of $10.00 per share pursuant to the PIPE Investment.

Collectively these transactions are referred to as the “Transaction Adjustments”, described in the accompanying notes. STPC and Benson Hill are collectively referred to herein as the “Companies,” and the Companies, subsequent to the merger, STPC’s IPO, the Benson Hill Preferred Conversion, the Debt Payoff and the PIPE Investment, are referred to herein as “New Benson Hill.”

The unaudited pro forma condensed combined statements of operations for the six months ended June 30, 2021 and the year ended December 31, 2020 give effect to the Transaction Adjustments as if they had occurred on January 1, 2020. The unaudited pro forma condensed combined balance sheet as of June 30, 2021 gives effect to the Transaction Adjustments as if they had occurred on June 30, 2021. The unaudited pro forma condensed combined financial statements have been presented for illustrative purposes only and do not necessarily reflect what New Benson Hill’s financial condition or results of operations would have been had the Transaction Adjustments occurred on the dates indicated. Further, the unaudited pro forma condensed combined financial information also may not be useful in predicting the future financial condition and results of operations of New Benson Hill. The actual financial position and results of operations may differ significantly from the pro forma amounts reflected herein due to a variety of factors. The Transaction Adjustments represent management’s estimates based on information available as of the date of these unaudited pro forma condensed combined financial statements and are subject to change as additional information becomes available and analyses are performed.

The historical financial information of STPC was derived from the unaudited condensed consolidated financial statements of STPC as of and for the six months ended June 30, 2021 and the audited financial statements of STPC as of December 31, 2020 and for the period from October 8, 2020 (inception) through December 31, 2020, which are included elsewhere in this proxy statement/prospectus. The historical financial information of Benson Hill was derived from the unaudited condensed consolidated financial statements of Benson Hill as of and for the six months ended June 30, 2021 and the audited consolidated financial statements of Benson Hill as of and for the year ended December 31, 2020, which are included elsewhere in this proxy statement/prospectus. The unaudited pro forma condensed combined financial information is based on and should be read in conjunction with the audited and unaudited historical financial statements of each of STPC and Benson Hill and the notes thereto, as well as the disclosures contained in the sections titled “STPC’s Management’s Discussion and Analysis of Financial Condition and Results of Operations” and “Benson Hill’s Management’s Discussion and Analysis of Financial Condition and Results of Operations” and other financial information included elsewhere in this proxy statement/prospectus.

Description of the Transaction

On May 8, 2021, STPC, Merger Sub and Benson Hill entered into the merger agreement, pursuant to which Benson Hill will be merged with and into Merger Sub, with Benson Hill surviving the merger. After

62

giving effect to the merger, STPC will own, directly or indirectly, all of the issued and outstanding equity interests of Benson Hill and its subsidiaries and will become New Benson Hill. Existing Benson Hill equity holders will hold a portion of the common stock of New Benson Hill.

Subject to the terms and conditions of the merger agreement, the consideration to be received by the Existing Benson Hill equity holders in connection with the merger will be 130 million shares of New Benson Hill Common Stock, valued at $10.00 per share for total merger consideration of $1.3 billion. These shares will be allocated pro-rata among the holders of Existing Benson Hill Common Stock on a fully-diluted and as-converted to Existing Benson Hill Common Stock basis, including the number of shares of Existing Benson Hill Common Stock issuable upon the Benson Hill Preferred Conversion and the number of shares of Existing Benson Hill Common Stock subject to outstanding Benson Hill Options. If the merger took place on June 30, 2021 on a pro forma basis, out of the 130 million shares of New Benson Hill Company Stock that would be received by Pre-Closing Holders, approximately 119.3 million shares would be allocated to holders of Existing Benson Hill Common Stock and Benson Hill Preferred Stock and 13.0 million shares would be reserved for New Benson Hill Options (comprised of 10.7 million Net New Benson Hill Options and 2.3 million Exercise Price Options) to be issued in exchange for corresponding Benson Hill Options.

In addition, immediately after the completion of the merger, certain investors have agreed to subscribe for and purchase an aggregate of $225.0 million of New Benson Hill Common Stock in connection with the PIPE Investment at a value of $10.00 per share.

In connection with the merger, certain Pre-Closing Holders will receive approximately 17.6 million Earn Out Shares contingent upon achieving certain market share price milestones within the Earn Out Period. These Earn Out Shares will be forfeited if the set milestones are not reached. The Earn Out Shares include voting rights and are eligible to receive nonforfeitable dividends to the extent dividends are declared but does not contractually obligate the holders of such shares to participate in losses.

All settlement scenarios associated with the Earn Out Shares, including those under fundamental change events, are indexed to New Benson Hill’s own common stock. As such, the Earn Out Shares are treated as an equity classified contract.

Earn Out Awards with a value equivalent to 2.0 million shares of New Benson Hill Common Stock, which are subject to the same vesting terms and conditions as the Earn Out Shares, are not incorporated into the unaudited condensed combined financial information because they will be granted only subsequent to the merger under the Incentive Plan to certain holders of Benson Hill Options. The value of the Earn Out Awards, to be determined at issuance subsequent to the merger, is expected to be recognized as a stock compensation expense consistent with GAAP.

The following summarizes the number of shares of New Benson Hill Common Stock outstanding following the consummation of the merger, STPC’s IPO, and the PIPE Investment under the two scenarios, at the consummation of the merger excluding the potential dilutive effect of the exercise or vesting of warrants and stock options:

​	No redemption scenario				Maximum redemption scenario
​	Shares		%		Shares		%
Benson Hill Stockholders(1)	​	136,841,207	​	65.3%	​	136,841,207	​	80.8%
STPC Public Stockholders	​	40,250,000	​	19.2%	​	—	​	—
STPC Founder Shares(1)	​	10,062,500	​	4.8%	​	10,062,500	​	5.9%
Total STPC Shares	​	50,312,500	​	24.0%	​	10,062,500	​	5.9%
PIPE Investors	​	22,500,000	​	10.7%	​	22,500,000	​	13.3%
Total	​	209,653,707	​	100.0%	​	169,403,707	​	100.0%

(1)

Figures and percentages include the 17.6 million Earn Out Shares and the 2.0 million Sponsor Earn Out Shares but exclude the 13.0 million New Benson Hill Options (comprised of 10.7 million Net New Benson Hill Options and 2.3 million Exercise Price Options). See “Proposal No. 7  —  The Incentive

63

Plan Proposal” for additional information. See “Basis of Presentation and Glossary” for additional information with respect to assumptions underlying New Benson Hill share calculations and ownership percentages.

Accounting Treatment

The merger will be accounted for as a reverse recapitalization because Benson Hill has been determined to be the accounting acquirer in accordance with GAAP under both the no redemption and maximum redemption scenarios. Under this method of accounting, STPC will be treated as the “acquired” company for financial reporting purposes. Accordingly, the merger will be treated as the equivalent of Benson Hill issuing stock for the net assets of STPC, accompanied by a recapitalization. The net assets of STPC will be stated at historical cost, with no goodwill or other intangible assets recorded. Operations prior to the merger will be those of Benson Hill. This accounting treatment determination was primarily based on the following:

•

The Pre-Closing Holders will hold the majority of voting rights in New Benson Hill or be the largest single voting interest block in New Benson Hill, in the maximum and minimum redemption scenarios, respectively;

•

The pre-combination directors of Benson Hill will be the majority of the directors on the board of directors of New Benson Hill;

•

Senior management of Benson Hill will comprise the senior management of New Benson Hill; and

•

Operations of Benson Hill will comprise the ongoing operations of New Benson Hill.

Basis of Pro Forma Presentation

The following unaudited pro forma condensed combined financial information has been prepared in accordance with Article 11 of Regulation S-X. The historical financial information of STPC and Benson Hill has been adjusted in the unaudited pro forma condensed combined financial information to give effect to events that are (1) directly attributable to the merger, the consummation of STPC’s IPO, the Benson Hill Preferred Conversion, the Debt Payoff and the PIPE Investment, (2) factually supportable, and (3) with respect to the statement of operations, expected to have a continuing impact on the combined results.

The unaudited pro forma condensed combined financial information has been prepared using the assumptions below with respect to the potential redemption of shares of STPC Class A Common Stock into cash:

•

Assuming No Redemptions: This presentation assumes that no STPC stockholders exercise redemption rights with respect to their shares of Class A Common Stock.

•

Assuming Maximum Redemptions: This scenario assumes that 40,250,000 shares of STPC’s Class A Common Stock are redeemed pursuant to their redemption rights at a redemption price of approximately $10.00 per share. The maximum redemption amount is derived to ensure a minimum consolidated cash balance of $225 million. This minimum cash balance is calculated before giving effect to payment of estimated transaction expenses of $49.7 million. This scenario includes all adjustments contained in above scenario but presents additional adjustments to reflect the effect of the maximum redemptions.

Management has made significant estimates and assumptions in its determination of the pro forma adjustments. As the unaudited pro forma condensed combined financial information has been prepared based on these preliminary estimates, the final amounts recorded may differ materially from the information presented.

If the actual facts are different than these assumptions, then the amounts and shares outstanding in the unaudited pro forma condensed combined financial information will be different. The unaudited pro forma condensed combined financial information do not reflect the income tax effects of the pro forma adjustments as any change in the deferred tax balance would be offset by an increase in the valuation allowance given that Benson Hill incurred significant losses during the historical periods presented.

64

The unaudited pro forma condensed combined information contained herein assumes that the STPC stockholders approve the merger. STPC’s public stockholders may elect to redeem their shares of Class A Common Stock for cash even if they approve the merger. STPC cannot predict how many of its public stockholders will exercise their right to have their shares of Class A Common Stock redeemed for cash. As a result, New Benson Hill has provided the unaudited pro forma condensed combined financial information under two different redemption scenarios, which produce different allocations of total New Benson Hill equity between holders of the ordinary shares. The first scenario, or “no redemption scenario,” assumes that none of STPC’s public stockholders will exercise their right to have their shares of Class A Common Stock redeemed for cash, and the second scenario, or “maximum redemption scenario,” assumes that holders of the maximum number of shares of Class A Common Stock that could be redeemed for cash while still leaving sufficient cash available to consummate the merger will exercise their right to have their shares redeemed for cash. The actual results will be within the parameters described by the two scenarios. However, there can be no assurance regarding which scenario will be closest to the actual results.

Transaction Adjustments

Adjustments included in the unaudited pro forma condensed combined balance sheet as of June 30, 2021 are as follows:

All Scenario Transaction Adjustments

68

(a)

Represents the reclassification of marketable securities held in a STPC trust account that becomes available to fund the merger.

(b)

Represents the issuance to certain investors, as part of the PIPE Investment, of 22.5 million shares of Class A Common Stock of STPC pursuant to the PIPE Agreements at a price of $10.00 per share.

(c)

Reflects payment of transaction costs anticipated in consummating the merger in the amount of approximately $50.0 million ($0.3 million of which was prepaid), including the payment of deferred underwriting and other transaction fees of $14.1 million associated with STPC’s IPO.

STPC SPECIAL MEETING OF STOCKHOLDERS

General

STPC is furnishing this proxy statement/prospectus to its stockholders as part of the solicitation of proxies by the board of directors for use at the STPC Special Meeting to be held on            , 2021 and at any adjournment or postponement thereof. This proxy statement/prospectus provides STPC’s stockholders with information they need to know to be able to vote or direct their vote to be cast at the STPC Special Meeting.

Date, Time and Place

The STPC Special Meeting will be held on            , 2021, at       Eastern Time, via a virtual meeting. On or about      , 2021, STPC commenced mailing this proxy statement/prospectus and the enclosed form of proxy to its stockholders entitled to vote at the STPC Special Meeting.

Purpose of STPC Special Meeting

STPC stockholders are being asked to vote on the following proposals:

1.

the Business Combination Proposal;

2.

the Charter Proposals;

3.

the NYSE Proposal;

4.

the Incentive Plan Proposal; and

5.

the Adjournment Proposal (if necessary).

Recommendation of the STPC Board of Directors

The STPC board of directors has unanimously determined that the merger, on the terms and conditions set forth in the merger agreement, is advisable and in the best interests of STPC and its stockholders and has directed that the proposals set forth in this proxy statement/prospectus be submitted to its stockholders for approval at the STPC Special Meeting on the date and at the time and place set forth in this proxy statement/prospectus. The STPC board of directors unanimously recommends that STPC’s stockholders vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposals, “FOR” the NYSE Proposal, “FOR” the Incentive Plan Proposal and “FOR” the Adjournment Proposal (if necessary).

Voting Power; Record Date

You will be entitled to vote or direct votes to be cast at the STPC Special Meeting if you owned shares of STPC common stock at the close of business on            , 2021, which is the record date for the STPC Special Meeting. You are entitled to one (1) vote for each share of STPC common stock that you owned as of the close of business on the STPC record date. If your shares are held in “street name” or are in a margin or similar account, you should contact your broker, bank or other nominee to ensure that votes related to the shares you beneficially own are properly counted. On the STPC record date, there were      shares of common stock outstanding, of which     are shares of Class A Common Stock and 10,062,500 are Founder Shares.

Vote of the Sponsor and STPC’s Directors and Officers

STPC has entered into agreements with the Sponsor and STPC’s officers and directors pursuant to which (i) each has agreed to vote any shares of STPC common stock owned by it in favor of the Business Combination Proposal, (ii) each has agreed to waive certain of their anti-dilution and conversion rights and (iii) Sponsor has agreed to convert 1,996,500 shares of its Class B Common Stock into the Sponsor Earn Out Shares.

71

The Sponsor has waived any redemption rights, including with respect to shares of STPC common stock purchased in STPC’s IPO or in the aftermarket, in connection with merger. The Founder Shares held by the Sponsor have no redemption rights upon STPC’s liquidation and will be worthless if no business combination is effected by STPC by January 8, 2023. However, the Sponsor is entitled to redemption rights upon STPC’s liquidation with respect to any shares of Class A Common Stock they may own.

Quorum and Required Vote for Proposals for the STPC Special Meeting

A quorum of STPC stockholders is necessary to hold a valid meeting. A quorum will be present at the STPC Special Meeting if a majority of the issued and outstanding STPC common stock entitled to vote as of the STPC record date at the STPC Special Meeting is represented virtually or by proxy. Abstentions and broker non-votes will be counted as present for the purpose of determining a quorum. The holders of the Founder Shares, who currently own 20% of the issued and outstanding shares of STPC common stock, will count towards this quorum. As of the STPC record date for the STPC Special Meeting,      shares of STPC common stock would be required to achieve a quorum.

Approval of the Business Combination Proposal, the NYSE Proposal and the Incentive Plan Proposal require the affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class at a meeting at which a quorum is present.

Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the then-outstanding shares of STPC common stock, voting together as a single class, and the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting separately as a single class. Approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast by holders of common stock, voting together as a single class, regardless of whether a quorum is present. The STPC board of directors has already approved each of the proposals.

If STPC stockholders fail to approve the Business Combination Proposal or the NYSE Proposal, or, unless otherwise waived by Benson Hill and STPC, the Charter Proposals or the Incentive Plan Proposal, the merger will not occur. The Charter Proposals and the Incentive Plan Proposal are conditioned on the approval of the Business Combination Proposal and the NYSE Proposal. The Adjournment Proposal is not conditioned on the approval of any other proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the stockholders for a vote. It is important for you to note that in the event that the Business Combination Proposal does not receive the requisite vote for approval, then the merger may not be consummated. If STPC does not consummate the merger and fails to complete an initial business combination by January 8, 2023, STPC will be required to dissolve and liquidate its Trust Account by returning the then remaining funds in such account to the public stockholders.

Recommendation of the STPC Board of Directors

STPC’s board of directors unanimously determined that the merger agreement and the transactions contemplated thereby, including the merger, were advisable and in the best interests of, STPC and its stockholders. Accordingly, STPC’s board of directors unanimously recommends that its stockholders vote “FOR” the Business Combination Proposal and the other proposals hereby.

When you consider the recommendation of STPC’s board of directors in favor of approval of these proposals, you should keep in mind that STPC’s directors and officers have interests in the merger that are different from or in addition to (and which may conflict with) your interests as a stockholder. These interests include, among other things:

•

If the merger or another business combination is not consummated by January 8, 2023, STPC will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Class A Common Stock for cash and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating. In such event, the 10,062,500 Founder Shares held by the Sponsor, our directors and our senior advisor, which was acquired for an aggregate purchase price of $25,000 prior to STPC’s IPO, would be worthless because the holders are not entitled to participate in any

72

redemption or distribution with respect to such shares. Such shares had an estimated aggregate market value of $ based upon the closing price of $ per public share on the NYSE on      , 2021, the STPC record date.

•

The Sponsor purchased an aggregate of 6,553,454 Private Placement Warrants from STPC for an aggregate purchase price of $13,106,909 (or $2.00 per warrant) in a private placement. These purchases took place on a private placement basis simultaneously with the consummation of STPC’s IPO. A portion of the proceeds STPC received from these purchases were placed in the Trust Account. Such warrants had an estimated aggregate value of $      based on the closing price of $     per public warrant on the NYSE on      , 2021, the STPC record date. The Private Placement Warrants will become worthless if STPC does not consummate a business combination by January 8, 2023.

•

If STPC is unable to complete a business combination within the required time period, its executive officers will be personally liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by STPC for services rendered or contracted for or products sold to STPC. If STPC consummates a business combination, on the other hand, STPC will be liable for all such claims.

•

STPC’s officers and directors, and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on STPC’s behalf, such as identifying and investigating possible business targets and business combinations. Out-of-pocket expenses reimbursed to officers, directors and their affiliates total approximately $25,000. However, if STPC fails to consummate a business combination within the required period, they will not have any claim against the Trust Account for reimbursement. Accordingly, STPC may not be able to reimburse these expenses if the merger or another business combination, are not completed by January 8, 2023.

•

The continued indemnification of current directors and officers and the continuation of directors’ and officers’ liability insurance.

Abstentions and Broker Non-Votes

Abstentions and broker non-votes will be counted as present for the purpose of determining a quorum. For purposes of approval, a failure to vote, an abstention or a broker non-vote will have no effect on the Business Combination Proposal and the Adjournment Proposal. However, a failure to vote, an abstention or a broker non-vote will have the same effect as a vote “AGAINST” the Charter Proposals. Under Delaware law, a stockholder’s failure to vote, as well as an abstention from voting and a broker non-vote, will have no effect on the NYSE Proposal and the Incentive Plan Proposal. However, for purposes of the NYSE Proposal and the Incentive Plan Proposal, the NYSE considers an abstention vote as a “vote cast”, and therefore, an abstention will have the same effect as a vote “AGAINST” such proposals.

Voting Your Shares

Each share of STPC common stock that you own in your name entitles you to one (1) vote on each of the proposals for the STPC Special Meeting. Your one or more proxy cards show the number of shares of STPC common stock that you own. There are several ways to have your shares of common stock voted:

•

You can submit a proxy to vote your shares by calling the toll-free number shown on your proxy card and voting over the phone.

•

You can submit a proxy to vote your shares by visiting the website shown on your proxy card and voting via the internet.

•

You can submit a proxy to vote your shares by completing, signing, dating and returning the enclosed proxy card in the postage-paid envelope provided. If you hold your shares in “street name” through a bank, broker or other nominee, you will need to follow the instructions provided to you by your bank, broker or other nominee to ensure that your shares are represented and voted at the STPC Special Meeting. If you submit a proxy card, your “proxy,” whose name is listed on the proxy card, will vote your shares as you instruct on the proxy card. If you sign and return the proxy card but do not give instructions on how to vote your shares, your shares of STPC common stock will be

73

voted as recommended by STPC’s board of directors. STPC’s board of directors unanimously recommends that STPC’s stockholders vote “FOR” the Business Combination Proposal, “FOR” the Charter Proposals, “FOR” the NYSE Proposal, “FOR” the Incentive Plan Proposal and “FOR” the Adjournment Proposal (if necessary).

•

You can attend the STPC Special Meeting and vote virtually even if you have previously voted by submitting a proxy pursuant to any of the methods noted above. However, if your shares of STPC common stock are held in the name of your broker, bank or other nominee, you must get a proxy from the broker, bank or other nominee. That is the only way STPC can be sure that the broker, bank or nominee has not already voted your shares of STPC common stock.

Revoking Your Proxy

If you are a record owner of your shares and you give a proxy, you may change or revoke it at any time before it is exercised by doing any one of the following:

•

you may send another proxy card with a later date;

•

you may notify STPC’s secretary in writing before the STPC Special Meeting that you have revoked your proxy; or

•

you may attend the STPC Special Meeting virtually, revoke your proxy, and vote online as described above.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker for information on how to change or revoke your voting instructions.

No Additional Matters May be Presented at the STPC Special Meeting

The STPC Special Meeting has been called only to consider the approval of the Business Combination Proposal, the Charter Proposals, the NYSE Proposal, the Incentive Plan Proposal and the Adjournment Proposal (if necessary). Under STPC’s bylaws, no other matters may be considered at the STPC Special Meeting if they are not included in this proxy statement/prospectus, which serves as the notice of the STPC Special Meeting.

Who Can Answer Your Questions About Voting

If have any questions about how to vote or direct a vote in respect of your shares of STPC common stock, you may call Morrow Sodali, STPC’s proxy solicitor, toll-free at (800) 662-5200 (banks and brokers call (203) 658-9400) or email Morrow Sodali at STPC.info@investor.morrowsodali.com.

Redemption Rights

Holders of Class A Common Stock may seek to redeem their shares for cash, regardless of whether they vote for or against, or whether they abstain from voting on, the Business Combination Proposal. Any stockholder holding Class A Common Stock may demand that STPC redeem such shares for a full pro rata portion of the Trust Account (which, for illustrative purposes, was $10.00 per share as of June 30, 2021, calculated as of two (2) business days prior to the anticipated consummation of the merger). If a holder properly seeks redemption as described in this section and the merger with Benson Hill is consummated, STPC will redeem these shares for a pro rata portion of funds deposited in the Trust Account and the holder will no longer own these shares following the merger.

Notwithstanding the foregoing, a holder of Class A Common Stock, together with any affiliate of his or any other person with whom he is acting in concert or as a “group” ​(as defined in Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to more than 15% of the Class A Common Stock. Accordingly, no shares of Class A Common Stock in excess of 15% held by a public stockholder, together with any affiliate of such holder or any other person with whom such holder is acting in concert or as a “group,” will be redeemed for cash.

Holders of Founder Shares will not have redemption rights with respect to such shares.

74

Holders may demand redemption by delivering their stock, either physically or electronically using Depository Trust Company’s DWAC System, to STPC’s transfer agent no later than 5:00 p.m., Eastern Time, on the second business day prior to the vote at the STPC Special Meeting. If you hold the shares in “street name,” you will have to coordinate with your broker to have your shares certificated or delivered electronically. Certificates that have not been tendered (either physically or electronically) in accordance with these procedures will not be redeemed for cash. There is a nominal cost associated with this tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $100.00 and it would be up to the broker whether or not to pass this cost on to the redeeming stockholder. In the event the proposed merger is not consummated this may result in an additional cost to stockholders for the return of their shares.

STPC’s transfer agent can be contacted at the following address:

Continental Stock Transfer & Trust Company
One State Street, 30th Floor
New York, New York 10004
Attention: Mark Zimkind
mzimkind@continentalstock.com

Any request to redeem such shares, once made, may be withdrawn at any time up to the vote on the Business Combination Proposal. Furthermore, if a holder of a public share delivered its certificate in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request that the transfer agent return the certificate (physically or electronically).

If the merger is not approved or completed for any reason, then STPC’s public stockholders who elected to exercise their redemption rights will not be entitled to redeem their shares for a full pro rata portion of the Trust Account, as applicable. In such case, STPC will promptly return any shares delivered by public holders. If STPC would be left with less than $5,000,001 of net tangible assets as a result of the holders of Class A Common Stock properly demanding redemption of their shares for cash or the Minimum Cash Condition would not be satisfied, STPC will not be able to consummate the merger.

The closing price of Class A Common Stock on            , 2021, the STPC record date, was $      . The cash held in the Trust Account on such date was approximately $      million ($       per public share). Prior to exercising redemption rights, stockholders should verify the market price of Class A Common Stock as they may receive higher proceeds from the sale of their common stock in the public market than from exercising their redemption rights if the market price per share is higher than the redemption price. STPC cannot assure its stockholders that they will be able to sell their shares of Class A Common Stock in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when its stockholders wish to sell their shares.

If a holder of Class A Common Stock exercises his, her or its redemption rights, then he, she or it will be exchanging its shares of Class A Common Stock for cash and will no longer own those shares. You will be entitled to receive cash for these shares only if you properly demand redemption no later than 5:00 p.m., Eastern Time, on the second business day prior to the vote on the Business Combination Proposal by delivering your stock (either physically or electronically) to STPC’s transfer agent, and the merger is consummated.

For a detailed discussion of the material U.S. federal income tax considerations for stockholders with respect to the exercise of these redemption rights, see “Material U.S. Federal Income Tax Consequences” beginning on page 205. The consequences of a redemption to any particular stockholder will depend on that stockholder’s particular facts and circumstances. Accordingly, you are urged to consult your tax advisor to determine your tax consequences from the exercise of your redemption rights, including the applicability and effect of U.S. federal, state, local and non-U.S. income and other tax laws in light of your particular circumstances.

Appraisal Rights

Appraisal rights are not available to holders of shares of STPC common stock in connection with the merger.

75

Proxy Solicitation Costs

STPC is soliciting proxies on behalf of its board of directors. This solicitation is being made by mail but also may be made by telephone. STPC and its directors, officers and employees may also solicit proxies online. STPC will file with the SEC all scripts and other electronic communications as proxy soliciting materials. STPC will bear the cost of the solicitation.

STPC has hired Morrow Sodali to assist in the proxy solicitation process. STPC will pay to Morrow Sodali a fee of $        , plus disbursements.

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

The Sponsor

As of           , 2021, the STPC record date, the Sponsor and STPC’s directors owned of record and were entitled to vote an aggregate of 10,062,500 Founder Shares that were issued prior to STPC’s IPO. Such shares currently constitute 20% of the outstanding shares of STPC common stock. The Sponsor and STPC’s officers and directors have agreed to vote the Founder Shares, as well as any shares of STPC common stock acquired in the aftermarket, in favor of each of the proposals being presented at the STPC Special Meeting. The Founder Shares have no right to participate in any redemption distribution and will be worthless if no business combination is effected by STPC.

76

INFORMATION ABOUT STPC

References in this section to “we,” “our,” “us,” the “Company,” or “STPC” generally refer to Star Peak Corp II.

General

STPC is a blank check company incorporated in Delaware for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. STPC is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

Initial Public Offering and Private Placement

In October 2020, our Sponsor purchased an aggregate of 10,062,500 Founder Shares for an aggregate purchase price of $25,000, or approximately $0.003 per share. Prior to the initial investment in the company of $25,000 by our Sponsor, the company had no assets, tangible or intangible. On January 4, 2021, our Sponsor transferred 40,000 Founder Shares to each of Desirée Rogers and C. Park Shaper, our independent directors.

On January 8, 2021, STPC completed its IPO of 40,250,000 units generating gross proceeds of $402,500,000. On January 8, 2021, the underwriters fully exercised the over-allotment option and purchased an additional 5,250,000 units, at a price of $10.00 per unit (“units”), generating gross proceeds of $52,500,000. Each unit consists of one (1) share of Class A Common Stock, par value $0.0001, and one-fourth (1/4) of one (1) redeemable warrant. Each whole warrant entitles the holder thereof to purchase one (1) share of Class A Common Stock at a price of $11.50 per share, subject to certain adjustments.

Concurrently with the completion of STPC’s IPO, the Sponsor purchased an aggregate of 6,553,454 Private Placement Warrants, including an additional 525,000 Private Placement Warrants that were issued in connection with the exercise of the underwriters’ overallotment option, at a price of $2.00 per warrant, or $13,106,909 in the aggregate. The purchase price of the Private Placement Warrants was added to the net proceeds of STPC’s IPO and placed in the Trust Account such that the Trust Account held $402,500,000 million at the time of closing of STPC’s IPO. Each whole Private Placement Warrant entitles the holder thereof to purchase one (1) share of Class A Common Stock at a price of $11.50 per share, subject to certain adjustments.

Fair Market Value of Target Business

The NYSE rules require that STPC’s initial business combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting discounts and commissions and taxes payable on the income earned on the Trust Account) at the time of the agreement to enter into the initial business combination. The fair market value of the target or targets is determined by STPC’s board of directors based on one or more standards generally accepted by the financial community, such as discounted cash flow valuation or value of comparable businesses. STPC’s board of directors determined that this test was met in connection with the proposed business combination with Benson Hill as described in the section titled “The Merger” in this proxy statement/prospectus.

Stockholder Approval of Merger and Redemptions

Under STPC’s Existing Charter, in connection with any proposed business combination, STPC is required to seek stockholder approval of a business combination at a meeting called for such purpose. Pursuant to the terms of this transaction as described in the section titled “STPC Special Meeting of Stockholders” in this proxy statement/prospectus, STPC is seeking stockholder approval at a meeting called for such purpose at which public stockholders may seek to redeem their Class A Common Stock upon the completion of an initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial business combination, including interest earned on the funds held in the trust account and not previously

77

released to STPC to pay its taxes, including franchise and income taxes, divided by the number of then-outstanding public shares. Public stockholders may redeem all or a portion of their shares, regardless of whether they vote for or against the proposed business combination, subject to the limitations described and procedures set forth in this proxy statement/prospectus. There will be no redemption rights upon the completion of an initial business combination with respect to STPC Warrants.

STPC will complete the merger only if the holders of a majority of the outstanding shares of the STPC common stock, voting together as a single class, vote in favor of the merger. A majority of the voting power of the issued and outstanding STPC common stock entitled to vote at the STPC Special Meeting must be present online or represented by proxy, at the STPC Special Meeting to constitute a quorum and in order to conduct business. The holders of the Founder Shares, who collectively beneficially own approximately 20% of the issued and outstanding shares of STPC common stock, will count toward this quorum.

Voting Restrictions in Connection with Stockholder Meeting

Pursuant to the terms of the Letter Agreement entered into with STPC, the Sponsor and STPC’s officers and directors have agreed to vote any Founder Shares held by them and any shares of Class A Common Stock purchased during or after STPC’s IPO in favor of an initial business combination. See “Other Agreements — STPC Letter Agreement,” beginning on page 188 of this proxy statement/prospectus, for more information. The Sponsor, STPC’s directors and officers and their permitted transferees own at least 20% of its outstanding common stock entitled to vote thereon. The quorum and voting thresholds at the STPC Special Meeting the Letter Agreement may make it more likely that STPC will consummate the merger. In addition, pursuant to the terms of the Letter Agreement, the Sponsor and STPC’s officers and directors have agreed to waive their redemption rights with respect to any Founder Shares and any shares of Class A Common Stock held by them in connection with the completion of an initial business combination.

Liquidation if No Initial Business Combination

STPC’s Existing Charter provides that it has until January 8, 2023 to complete an initial business combination. If STPC is unable to complete an initial business combination by such date, STPC will: (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Class A Common Stock, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to STPC to pay its taxes, including franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding shares of Class A Common Stock, which redemption will completely extinguish public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law; and (iii) as promptly as reasonably possible following such redemption, subject to the approval of its remaining stockholders and STPC’s board of directors, dissolve and liquidate, subject in each case to STPC’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to its warrants, which will expire worthless if STPC fails to complete an initial business combination by January 8, 2023.

Pursuant to the Letter Agreement, the Sponsor and STPC’s officers and directors have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares they hold if STPC fails to consummate an initial business combination within 24 months from the closing of STPC’s IPO. The Sponsor and STPC’s directors and officers will be entitled to liquidating distributions from the Trust Account with respect to any shares of Class A Common Stock they hold if STPC fails to complete its initial business combination within the prescribed time frame.

Pursuant to the Letter Agreement, the Sponsor and STPC’s executive officers and directors have agreed that they will not propose any amendment to STPC’s Existing Charter that would modify the substance or timing of STPC’s obligation to provide holders of its Class A Common Stock the right to have their shares redeemed in connection with its initial business combination or to redeem 100% of STPC’s public shares if it does not complete its initial business combination within 24 months from the closing of its IPO or with respect to any other provision relating to the rights of holders of STPC’s Class A Common

Stock unless STPC provides its public stockholders with the opportunity to redeem their shares of Class A Common Stock upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, including franchise and income taxes, divided by the number of the then-outstanding shares of Class A Common Stock. However, STPC will not redeem its Class A Common Stock in an amount that would cause its net tangible assets to be less than $5,000,001.

STPC expects that all costs and expenses associated with implementing its plan of dissolution, as well as payments to any creditors, will be funded from amounts remaining out of the approximately $      million of proceeds held outside the Trust Account as of                 , 2021, although STPC cannot assure you that there will be sufficient funds for such purpose. However, if those funds are not sufficient to cover the costs and expenses associated with implementing its plan of dissolution, to the extent that there is any interest accrued in the Trust Account not required to pay taxes, STPC may request the trustee to release to it an additional amount of up to $100,000 of such accrued interest to pay those costs and expenses.

If STPC were to expend all of the net proceeds of its IPO and the sale of the Private Placement Warrants, other than the proceeds deposited in the Trust Account, and without taking into account interest, if any, earned on the Trust Account, the per-share redemption amount received by stockholders upon STPC’s dissolution would be approximately $10.00. The proceeds deposited in the Trust Account could, however, become subject to the claims of STPC’s creditors which would have higher priority than the claims of its public stockholders. STPC cannot assure you that the actual per-share redemption amount received by stockholders will not be reduced to less than $10.00 per public share. While STPC intends to pay such amounts, if any, it cannot assure you that it will have funds sufficient to pay or provide for all creditors’ claims.

Although STPC seeks to have all vendors, service providers (except STPC’s independent registered public accounting firm), prospective target businesses or other entities with which it does business execute agreements with it waiving any right, title, interest or claim of any kind in or to any monies held in the Trust Account for the benefit of its public stockholders, such parties may not execute such agreements, or even if they execute such agreements, they may not be prevented from bringing claims against the Trust Account including, but not limited to, fraudulent inducement, breach of fiduciary responsibility or other similar claims, as well as claims challenging the enforceability of the waiver, in each case in order to gain advantage with respect to a claim against STPC’s assets, including the funds held in the Trust Account. If any third-party refuses to execute an agreement waiving such claims to the monies held in the Trust Account, STPC’s management will perform an analysis of the alternatives available to it and will only enter into an agreement with a third-party that has not executed a waiver if management believes that such third-party’s engagement would be significantly more beneficial to STPC than any alternative. Examples of possible instances where STPC may engage a third-party that refuses to execute a waiver include the engagement of a third-party consultant whose particular expertise or skills are believed by management to be significantly superior to those of other consultants that would agree to execute a waiver or in cases where management is unable to find a service provider willing to execute a waiver.

In addition, there is no guarantee that such entities will agree to waive any claims they may have in the future as a result of, or arising out of, any negotiations, contracts or agreements with STPC and will not seek recourse against the Trust Account for any reason. Upon redemption of the Class A Common Stock, if STPC is unable to complete its initial business combination within the prescribed time frame, or upon the exercise of a redemption right in connection with its initial business combination, STPC will be required to provide for payment of claims of creditors that were not waived that may be brought against STPC within the ten (10) years following redemption. The Sponsor has agreed that it will be liable to STPC if and to the extent any claims by a third-party (other than STPC’s independent registered public accounting firm and the underwriters of its IPO) for services rendered or products sold to STPC, or a prospective target business with which STPC has entered into a written letter of intent, confidentiality or any other similar agreement or business combination agreement, reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per public share and (ii) the actual amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per share due to reductions in the value of the trust assets, in each case net of the interest which may be withdrawn to pay taxes, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver

79

of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable) nor will it apply to any claims under STPC’s indemnity of the underwriters of its IPO against certain liabilities, including liabilities under the Securities Act. STPC has not asked its Sponsor to reserve for such indemnification obligations, nor has it independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and STPC believes that the Sponsor’s only assets are securities of its company. Therefore, STPC cannot assure you that its Sponsor would be able to satisfy those obligations. As a result, if any such claims were successfully made against the Trust Account, the funds available for STPC’s initial business combination and redemptions could be reduced to less than $10.00 per public share. None of STPC’s officers or directors will indemnify STPC for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

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

STPC will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than its independent registered public accounting firm), prospective target businesses or other entities with which STPC does business, execute agreements with it waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account. The Sponsor will also not be liable as to any claims under the indemnity of the underwriters of STPC’s IPO against certain liabilities, including liabilities under the Securities Act. STPC will have access to up to $      million of the proceeds held outside the Trust Account as of                 , 2021, with which to pay any such potential claims (including costs and expenses incurred in connection with its liquidation, currently estimated to be no more than approximately $      million). In the event that STPC liquidates and it is subsequently determined that the reserve for claims and liabilities is insufficient, stockholders who received funds from STPC’s Trust Account could be liable for claims made by creditors.

If STPC files a bankruptcy petition or an involuntary bankruptcy petition is filed against it that is not dismissed, the proceeds held in the Trust Account could be subject to applicable bankruptcy law, and may be included in STPC’s bankruptcy estate and subject to the claims of third parties with priority over the claims of STPC’s stockholders. To the extent any bankruptcy claims deplete the Trust Account, the per-share amount that would otherwise be received by our stockholders in connection with our liquidation may be reduced. Additionally, if the bankruptcy petition is not dismissed, any distributions received by stockholders could be viewed under applicable debtor/creditor and/or bankruptcy laws as either a “preferential transfer” or a “fraudulent conveyance.” As a result, a bankruptcy court could seek to recover some or all amounts received by STPC’s stockholders. Furthermore, STPC’s board may be viewed as having breached its fiduciary duty to STPC’s creditors and/or may have acted in bad faith, thereby exposing itself and STPC to claims of punitive damages, by paying public stockholders from the Trust Account prior to addressing the claims of creditors. STPC cannot assure you that claims will not be brought against STPC for these reasons.

STPC’s public stockholders will be entitled to receive funds from the Trust Account only upon the earliest to occur of: (i) the completion of the initial business combination; (ii) the redemption of any Class A Common Stock properly tendered in connection with a stockholder vote to amend STPC’s Existing Charter (A) to modify the substance or timing of STPC’s obligation to provide holders of STPC’s Class A Common Stock the right to have their shares redeemed in connection with its initial business combination or to redeem 100% of STPC’s Class A Common Stock if it does not complete the initial business combination within 24 months from the closing of its IPO, subject to applicable law and as further described herein, or (B) with respect to any other provisions relating to the rights of holders of STPC’s Class A Common Stock,

80

and (iii) the redemption of STPC’s Class A Common Stock if it has not consummated its business combination within 24 months from the closing of its IPO. Stockholders will not have any rights or interests in funds from the Trust Account, except under certain limited circumstances. In connection with the merger, a stockholder’s vote in connection with the initial business combination alone will not result in a stockholder’s redeeming its shares of STPC for an applicable pro rata share of the Trust Account. Such stockholder must have also exercised its redemption rights.

Facilities

Our executive offices are located at 1603 Orrington Avenue, 13th Floor, Evanston, Illinois 60201, and our telephone number is (847) 905-4500. The cost for our use of this space is included in the $10,000 per month fee we will pay to an affiliate of our Sponsor for office space, utilities, secretarial support and administrative services. We consider our current office space adequate for our current operations.

Employees

We currently have three officers. These individuals are not obligated to devote any specific number of hours to our matters but they intend to devote as much of their time as they deem necessary to our affairs until we have completed our initial business combination. The amount of time that they will devote in any time period will vary based on whether a target business has been selected for our initial business combination and the stage of the business combination process we are in.

Periodic Reporting and Financial Information

STPC has registered its units, Class A Common Stock and warrants under the Exchange Act and has reporting obligations, including the requirement that it file annual, quarterly and current reports with the SEC. In accordance with the requirements of the Exchange Act, STPC’s annual reports contain financial statements audited and reported on by its independent registered public accountants.

Legal Proceedings

There is no material litigation, arbitration or governmental proceeding currently pending against STPC or any members of its management team in their capacity as such.

Executive Compensation and Director Compensation

The following disclosure concerns the compensation of STPC’s executive officers and directors for the fiscal year ended December 31, 2020 (i.e., pre-business combination).

None of STPC’s executive officers or directors have received any cash compensation for services rendered to STPC. Commencing at the consummation of STPC’s initial public offering, STPC reimburses the sponsor for office space, secretarial and administrative services provided to the company in an amount not to exceed $10,000 per month.

In addition, STPC’s Sponsor, executive officers and directors, or any of their respective affiliates are being reimbursed for any out-of-pocket expenses incurred in connection with activities conducted on STPC’s behalf such as identifying potential target businesses and performing due diligence on suitable business combinations. Our audit committee reviews all payments that the company makes to the Sponsor, executive officers or directors, or their affiliates on a quarterly basis. Any such payments prior to an initial business combination are made using funds held outside the Trust Account. Other than quarterly audit committee review of such reimbursements, STPC does not have any additional controls in place for governing reimbursement payments to its directors and executive officers for their out-of-pocket expenses incurred on behalf of the company and in connection with identifying and consummating an initial business combination. Other than these payments and reimbursements, no compensation of any kind, including finder’s and consulting fees, is paid by STPC to our Sponsor, executive officers and directors, or any of their respective affiliates, prior to completion of the initial business combination.

After the completion of the initial business combination, directors or members of its management team who remain with New Benson Hill may be paid consulting or management fees from the combined company. For more information on post-combination company executive compensation, see “Management of Benson Hill After the Merger” beginning on page 139. It is unlikely the amount of management and executive compensation will be known at the time of the proposed business combination, because the directors of New Benson Hill will be responsible for determining executive officer and director compensation. Any compensation to be paid to STPC’s executive officers will be determined, or recommended to the board of directors of New Benson Hill for determination, by a compensation committee constituted solely of independent directors or a majority of the independent directors on New Benson Hill’s board of directors.

STPC’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

References to the “Company,” “our,” “us” or “we” refer to Star Peak Corp II. The following discussion and analysis of STPC’s financial condition and results of operations should be read in conjunction with STPC’s financial statements and the notes thereto contained elsewhere in this proxy statement/prospectus. Certain information contained in the discussion and analysis set forth below includes forward-looking statements that involve risks and uncertainties.

Overview

We are a blank check company incorporated in Delaware on October 8, 2020, and formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses. We intend to complete our initial business combination using cash from the proceeds of our IPO and the private placement of the Private Placement Warrants, our capital stock, debt or a combination of cash, stock and debt.

The registration statement for our IPO was declared effective on January 5, 2021. On January 8, 2021, we consummated the IPO of 40,250,000 units, which includes the full exercise by the underwriters of the over-allotment option to purchase an additional 5,250,000 units, at $10.00 per unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.9 million, inclusive of approximately $14.1 million in deferred underwriting commissions.

Simultaneously with the closing of the IPO, we consummated the private placement of 6,553,454 Private Placement Warrants at a price of $2.00 per warrant to our Sponsor, generating proceeds of approximately $13.1 million.

Upon the closing of the IPO and the private placement, an amount of $402.5 million ($10.00 per unit) from the net proceeds of the IPO and certain of the proceeds of the private placement was placed in a Trust Account located in the United States with CST acting as trustee, and invested only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as determined by us, until the earlier of: (i) the completion of a business combination and (ii) the distribution of the Trust Account as described below.

If we are unable to complete a business combination within 24 months from the closing of the IPO, or January 8, 2023, we will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the shares of Class A Common Stock, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, including franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding shares of Class A Common Stock , which redemption will completely extinguish the public stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to our obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

Proposed Business Combination

On May 8, 2021, we entered into the merger agreement with Merger Sub and Benson Hill, and certain related agreements, as further described in Note 1 to our condensed consolidated financial statements.

Liquidity and Capital Resources

As of June 30, 2021, we had approximately $1.6 million in cash, and a working capital deficit of approximately $48,000 (without taking into account tax obligations of approximately $141,000 that may be paid using investment income earned in the Trust Account).

87

Our liquidity needs prior to the consummation of the IPO were satisfied through the payment of $25,000 from our Sponsor to cover certain offering costs on our behalf in exchange for issuance of founder shares and loan proceeds from our Sponsor of $150,000 under a promissory note. We repaid the promissory note in full on January 8, 2021. Subsequent to the consummation of the IPO, our liquidity needs have been satisfied through the net proceeds from the consummation of the IPO and the private placement held outside of the Trust Account.

Based on the foregoing, management believes that we will have sufficient working capital and borrowing capacity to meet our needs through the earlier of the consummation of a business combination or one year from this filing. Over this time period, we will be using the funds held outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial business combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the business combination.

Results of Operations

Our entire activity from inception through June 30, 2021 has been related to our formation, the preparation for the IPO, and since the closing of the IPO, the search for a business combination target, including activities in connection with the proposed acquisition of Benson Hill. We have neither engaged in any operations nor generated any revenues to date. We will not generate any operating revenues until after completion of our initial business combination. We will generate non-operating income in the form of interest income on cash and cash equivalents. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses in connection with searching for, and completing, a business combination.

For the three months ended June 30, 2021, we had a net loss of approximately $3.6 million, which consisted of general and administrative expenses of approximately $2.6 million, franchise tax expense of approximately $49,000, and change in fair value of derivative liabilities of approximately $0.9 million, partially offset by investment income on the Trust Account of approximately $13,000.

For the six months ended June 30, 2021, we had a net loss of approximately $9.8 million, which consisted of general and administrative expenses of approximately $4.4 million, franchise tax expense of approximately $142,000, change in fair value of derivative liabilities of approximately $4.5 million, and financing costs to derivative warrant liabilities of approximately $828,000, partially offset by investment income on the Trust Account of approximately $129,000.

Contractual Obligations

Registration Rights

The holders of founder shares, Private Placement Warrants and warrants that may be issued upon conversion of working capital loans that may be issued to the Company (no such loans have been issued to date) by the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors in connection with funding an initial business combination, if any, (and any shares of Class A Common Stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of working capital loans) are entitled to registration rights pursuant to a registration rights agreement signed upon the consummation of the IPO. The holders of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial business combination. We will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

We granted the underwriters a 45-day option from the date of IPO to purchase up to 5,250,000 additional units to cover over-allotments, if any, at the IPO price less the underwriting discounts and commissions. The underwriters exercised the over-allotment option in full on January 8, 2021.

88

The underwriters were entitled to an underwriting discount of $0.20 per unit, or approximately $8.1 million in the aggregate, paid upon the closing of the IPO. In addition, the underwriters are entitled to a deferred fee of $0.35 per unit, or approximately $14.1 million in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete a business combination, subject to the terms of the underwriting agreement.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on our financial position, results of our operations and/or search for a target company, the specific impact is not readily determinable as of the date of the condensed consolidated financial statements. The condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Critical Accounting Policies

This management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to fair value of financial instruments and accrued expenses. We base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. We have identified the following as our critical accounting policies:

Class A Common Stock Subject to Possible Redemption

We account for our Class A Common Stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Class A Common Stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A Common Stock (including Class A Common Stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) are classified as temporary equity. At all other times, Class A Common Stock is classified as stockholders’ equity. Our Class A Common Stock feature certain redemption rights that are considered to be outside of our control and subject to the occurrence of uncertain future events. Accordingly, as of June 30, 2021, 35,236,895 shares of Class A Common Stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the condensed consolidated balance sheets, respectively. As of December 31, 2020, there were no shares of Class A Common Stock subject to possible redemption.

Derivative Warrant Liabilities

We do not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. We evaluate all of our financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and ASC 815-15. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The 10,062,500 warrants issued in connection with the IPO and the 6,553,454 Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, we recognize the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in our statement of operations. The fair value of the public warrants issued in connection with the IPO and Private Placement Warrants were initially measured at fair value using the Black-Scholes Option Pricing Method (“BSM”) and subsequently, the fair value of the Private Placement

89

Warrants has been estimated using the BSM each measurement date. The fair value of public warrants issued in connection with the IPO have subsequently been measured based on the listed market price of such warrants.

Net Loss Per Share of Common Stock

Our condensed statements of operations include a presentation of net income (loss) per share for Class A Common Stock subject to possible redemption in a manner similar to the two-class method of net income (loss) per common stock. Net income (loss) per share of common stock, basic and diluted, for Class A Common Stock is calculated by dividing the interest income earned on the Trust Account, less interest available to be withdrawn for the payment of taxes, by the weighted average number of shares of Class A Common Stock outstanding for the periods. Net income (loss) per share of common stock, basic and diluted, for Class B Common Stock is calculated by dividing the net income (loss), adjusted for income attributable to Class A Common Stock, by the weighted average number of shares of Class B Common Stock outstanding for the periods. Class B Common Stock includes the founder shares as these shares of common stock do not have any redemption features and do not participate in the income earned on the Trust Account.

The calculation of diluted net income (loss) per share of common stock does not consider the effect of the warrants issued in connection with the (i) IPO, (ii) exercise of over-allotment and (iii) private placement since the exercise price of the warrants is in excess of the average common stock price for the period and therefore the inclusion of such warrants would be anti-dilutive.

Recent Accounting Standards

Our management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying unaudited condensed financial statements.

In August 2020, the Financial Accounting Standards Board issued Accounting Standard Update (ASU) No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. As permitted by the standard, we have elected to early adopt this standard in our first quarter of 2021 with no impact upon adoption.

Off-Balance Sheet Arrangements

As of June 30, 2021, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K.

JOBS Act

The JOBS Act contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and under the JOBS Act are allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, the financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging

90

growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our IPO or until we are no longer an “emerging growth company,” whichever is earlier.

INFORMATION ABOUT BENSON HILL

Unless the context otherwise requires, all references in this section to “we,” “us,” or “our” refer to Benson Hill and its subsidiaries prior to the consummation of the merger.

Overview

Our purpose is to create food made better from the beginning.

We are a values-driven food technology company with a vision to build a healthier and happier world by unlocking nature’s genetic diversity with our food innovation engine. Our purpose is to catalyze and broadly empower innovation from plant to plate so great-tasting, healthy, affordable and sustainable food choices are available to everyone. Our CropOS® technology platform uniquely combines data science, plant science and food science to create innovative food, ingredient, and feed products — starting with a better seed.

Genomics has been used for decades to develop crops for our food system, but most agricultural companies have focused almost exclusively on increasing the yield of a few crops, resulting in commodity ingredients and a food system based on the quantity of calories available. While focus on quantity is important, it came with trade-offs in nutrient density and flavor. Minimal diversity in ingredient options also led food manufacturers to add costly water- and energy-intensive processing steps, and additives like sugar and salt to make up for attributes that were muted in crops over time.

Consumers are demanding food choices with simpler ingredients that benefit their health and the health of our planet. By combining proprietary data with artificial intelligence capabilities as well as advances in plant genomics with our go-to-market strategy, we believe we can accelerate the development and delivery of food and ingredient options that are designed to be better from the beginning — with a focus on both quantity and quality. Our approach aims to develop food, feed and ingredients that fuel affordable scaling and product differentiation for evolving consumer preferences, such as the exploding plant-based food market and interest in functional foods.

Our CropOS® food innovation engine is a proprietary, continuously learning and expanding product design and development platform that uses predictive breeding and other advanced breeding tools like CRISPR gene editing technology to tap into the vast, underutilized natural genetic diversity within a plant to unlock and restore desired attributes. We believe that the combination of the predictive capability of the CropOS® platform, the precision of our genomic tools, our Crop Accelerator (a controlled environment research facility anticipated to be operational by the end of 2021), and our extensive field testing network will enable us to develop differentiated products with targeted attributes much more quickly and cost effectively than traditional methods.

We are building an integrated go-to-market approach, leveraging the existing parts of the supply chain to create efficiencies and feedback loops between consumers, farmers, and seed developers that has been lacking across our siloed agri-food value chain. We are working to design products with the consumer in mind, contract with farmers to grow and buy back the harvest, preserve the product identity through processing, and ultimately sell food and ingredients directly to food companies and retailers. We believe this integration and control of the product throughout the complete supply chain will allow us to link data to outcomes in our CropOS® platform to fuel the next generation of products. Additionally, we believe this product information linkage will enable us to optimize environmental and social impacts, as well as traceability throughout product production.

Today, our business is comprised of two segments — our Ingredients Business and our Fresh Business. Our Ingredients Business is designed to fuel the fast-growing plant-based protein movement with a pipeline of soy products anticipated to launch near-term and yellow pea products anticipated to launch in the medium-term, including differentiated soy-based vegetable oils, animal feed, and our upcoming ultra high protein (UHP) soybeans, that are targeted to be commercialized in 2022. UHP soybeans, and other products in our pipeline, have the potential to reduce the costly water- and energy-intensive processing steps associated with producing protein concentrates and isolates, alleviating supply constraints to bring plant-based proteins to scale.

92

Our Fresh Business is being built to serve the growing consumer interest in the convergence between food and health. Today that segment includes our subsidiary, J&J Produce, Inc. (doing business as “J&J Family of Farms”), where we sell fresh produce products to major retail customers. We have initiated the establishment of research and development operations where we intend to use our CropOS® platform to unlock flavor, nutrition, and sustainability benefits in fresh produce over the long-term.

We strongly believe that our commitment to environmental and social issues impacting our planet and our purpose-driven culture are fundamental to our ability to achieve our mission. Environmental, Social and Governance (ESG) issues help guide our thinking and approach throughout the development and commercialization of our products, and our innovative culture is rooted in our Core Values — Be Bold, Be Inspired and Be Real. Our mission is to partner with nature using technology as the gateway, leveraging genomics as a proven lever to advance the food system. We believe our leading technology platform, go-to-market strategy, and purpose-driven culture will allow us to bridge the divide between evolving consumer preferences and quality traits already present within the genetic diversity of plants, and we believe we are positioned to drive the evolution of the food system.

Evolving Food Industry

The current global food system was designed decades ago to increase calories to help feed a growing population. However, rapidly changing consumer trends and enabling technology such as cloud computing, artificial intelligence and gene sequencing create the opportunity for us to design food and ingredients that are better from the beginning by leveraging the natural genetic diversity within plants.

Food- and diet-related health issues, including obesity and diabetes, are some of the most widespread health issues today and continue to increase. According to the Centers for Disease Control and Prevention, more than 65% of American adults are either overweight or have obesity and approximately 90% of Americans do not eat the recommended daily amount of fruits and vegetables. Based on data from the United States Department of Agriculture and the Milken Institute, Americans spend more on diet-related illnesses than on food itself.

The current food system has a substantial environmental impact on the planet. According to McKinsey, 27% of total greenhouse gas emissions are caused by agriculture and eight gigatons of carbon dioxide equivalent (GtCO2e) emissions are caused by cattle and dairy worldwide, equivalent to total U.S. emissions in 2016. As the existence of climate change has become more widely accepted, 67% of consumers are open to changing their eating habits that harm the environment according to The European Consumer Organisation, 39% of Americans are actively trying to incorporate more plant-based foods into their diets according to The Nielsen Corporation, and more than 50% of Americans are willing to reduce their meat intake according to a Yale Program on Climate Change Communication report.

As awareness of diet-related health issues and environmental concerns grow, consumers are emphasizing a healthier lifestyle and a desire for nutritionally rich foods that are better tasting, less processed, and more sustainable. These trends are increasing demand for higher valued, premium segments of the food industry, such as plant-based protein products. Companies across the value chain are working to formulate new products for this category with a focus on taste, nutrition, traceability, and sustainability. Achieving cost parity with meat and affordable scaling is profoundly important to realize the full potential of this product category. As a result of these major trends, food companies are looking for specialty ingredients and foods that satisfy customers’ evolving needs and drive sustainable practices.

We believe the current food supply chain is siloed with fundamental disconnects that prevent it from adapting to rapidly changing consumer demand. Grain processors and food manufacturers are largely limited to commodity ingredients which often require additives and masking agents to deliver an acceptable taste and texture profile for consumers.

We believe there is a better way.

It starts with seed made better from the beginning from plant to plate, and delivered in a manner that benefits both farmers and consumers as well as our planet. At Benson Hill, we are building such a system

93

with our leading technology platform and a go-to-market strategy that we believe will bridge the divide between evolving consumer preferences and the quality needed to deliver more nutritious foods and ingredients.

Our Strengths and Solution: Technology and CropOS® Platform

Designing crops that are better from the beginning means our design process starts with the consumer in mind. This approach to product development requires a unique assemblage of disciplines — specifically data science, plant science and food science. We designed our headquarters in St. Louis, Missouri to foster this intentional gathering of disciplines under one roof. Benson Hill occupies the majority of the approximately 160,000-square-foot facility, which boasts approximately 25,000 square feet of lab space. We are working on capturing consumer-relevant data on products through our food science department, along with insights from our integrated supply chain, from which we will draw meaningful and actionable linkages back to plants’ genetics and direct product development through a process we call food digitization.

We are developing products with our CropOS® platform through a three step, iterative “Design, Build, Test” process that improves in precision and intelligence with each turn of the flywheel. The key inputs to our approach are twofold. The first is an unparalleled data library comprising genotypic, phenotypic, and other ‘omic data on our crops, consumer insight data on our ingredients, and environmental data on our growing sites. The second is a robust machine learning capability, which leverages our data library to design before we build. We believe this combination of relevant data and advanced simulation gives us the opportunity to get our products to market more efficiently, faster, and on timelines that can more effectively respond to evolving consumer preferences and farmer needs.

In our Design step, the CropOS® platform employs a diverse array of simulations and predictions to execute the most efficient and cost-effective path to novel product development. The platform can consider billions of data points in millions of pipeline configurations to identify the starting parental plant breeding combinations, predict gene targets, and analyze optimal farm management and environmental conditions to guide eventual placement of improved varieties in the field. These state-of-the-art platform capabilities and enabling technologies allow us to assess the probability of success early in the research and development process, focusing resources and avoiding potentially expensive late-stage failures. In turn, this allows for a larger breadth of products to be designed.

Once an optimal path is identified, we enter our Build step. In this stage of our development process, candidate products are created through predictive breeding and genome editing. Our proprietary suite of gene editing technologies and intellectual property portfolio enable us to predictably and precisely edit the plant’s genome. We can leverage our knowledge of plant gene functions to unlock and restore lost or muted genetic variation that is within the natural diversity of the plant or knock out genes that are unwanted. This approach is distinguished from transgenic, or “GMO,” technology in that we are advancing natural genetic variation that could be achieved using traditional breeding approaches rather than introducing genes foreign to the species, as is the case in GMO technology.

Once construction is complete on our Crop Accelerator facility in St. Louis, Missouri, the Build step of our process will be accelerated using a controlled environment indoor product development facility (expected to be operational in late 2021). This approximately 47,000 square-foot facility will feature approximately 20,000 square feet of dynamically adaptive Conviron® growth houses and chambers that will be equipped with sophisticated sensor and environmental controls, including multi-channel LEDs, imaging capabilities, additive carbon dioxide, and temperature, humidity, and lighting controls. We believe this will enable rapid prototyping for product development with the goal of more than doubling annual crop growth cycles.

After a potential commercial product is built, it then enters our Test step where it is evaluated within our testing network (comprised of internal and third-party sites and capabilities) of approximately 100 field-level testing research sites and over 260 production sites. We believe our predictive optimization capability has the potential to maximize the return on our genetics by using proprietary placement models built on environmental and performance data to predict where to contract acres to lift protein content. We then use digital agriculture technology to collect on-farm data through our grower data partnership program and other relationships to enhance the CropOS® platform, further feeding our data flywheel. We believe grower data partnership programs and other relationships with our farmers will be integral to developing and executing our ESG strategy.

94

Environmental, Social and Governance Strategy

Environmental and social impact is inherent to our purpose and guides decisions and work across our company. We believe our ESG strategy is fundamental to achieving our vision and long-term profitability. We are striving to optimize the environmental impact of our facilities and operations, but we recognize the greatest potential for impact is through our product development process of designing seeds, ingredients, and food that drives social and environmental benefit throughout the food value chain, providing benefits to all stakeholders.

At the farm level, we believe our integrated business model will enable additional revenue opportunities for farmers through ecosystem service markets and allow us to drive conservation and regeneration farming practices. At the processing level, we are designing products that we believe will reduce water and energy intensive processing steps. And at the product level, we are designing products that we believe will enable improved scaling, affordability, and adoption of end products with environmental and social benefits, such as plant-based meats.

Benson Hill has developed an internal strategy including critical policies and processes to manage and assess our ESG success and impact. As a company, some of our primary ESG goals are the following:

•

Improve consumer access to nutrient rich and sustainable food choices. Driven by Millennial and Gen Z consumer behavior, 90% of U.S. consumers see food products with simple ingredients as healthier, according to Food Dive. In addition, according to Food Dive, 65% want their food to be functional, recognizing that food impacts one’s health. Our ESG strategy is focused on developing ingredients and products that meet the sustainability and nutritional demands of consumers. Benson Hill uses state of the art breeding tools and crop production practices across the crop portfolio to deliver on these endpoints. As an example, we are currently working on creating high protein ingredient options for plant-based meat manufacturers to develop and mature their existing ingredient supply chains. We believe our products are positioned to assist those manufacturers in meeting ingredient demand and reducing environmental impacts, facilitating the expansion of plant-based foods, and improving affordability and accessibility for such products across the US.

•

Develop nutrient rich and sustainable products and ingredient options food companies and retailers. Driven by growing consumer demand and climate-related risks, many food manufacturers have set ESG measurement and reporting programs, such as reporting on their own greenhouse gas (GHG) emission production. Benson Hill is positioned to assist in meeting food manufacturers' goals of reducing GHG emissions in their scope 3 supply chains by developing products with reduced environmental impact. For example, Benson Hill has conducted a consultant-led life cycle assessment on our UHP soybean meal product, and our preliminary results show a significant reduction in required GHG emissions and water use due to the reduction of processing steps, when compared to the average commodity soy protein concentrate. We believe this reduction in GHG emissions and water, among other product claims, will support our food manufacturer customers’ ESG objectives.

•

Improve farm cost-effectiveness and sustainability. Our farmers and growers are critical to our commercial success, and we value these partnerships greatly. Benson Hill’s on-farm ESG strategy addresses two key concerns for growers — first, ongoing pressure to reduce food production costs, and second, best practices for land and soil stewardship to ensure long-term viability. Our strategy is to directly collect agronomic performance data from the farm and provide recommendations for land conservation and regenerative practices, as well as enable profitable opportunities through input reduction or alternative revenue streams. Agronomic data collection will inform data-based decision making in our product life cycle assessments, company GHG emissions assessments, product development and many other business functions.

•

Meet consumer demands for supply chain transparency and traceability. Through our business model, we intend to maintain the integrity of our proprietary products through each stage of the supply chain, until the product is sold to our customers. We believe this enables us to enhance transparency and traceability, which is appealing to our customers. This approach provides us direct line of sight to data we intend to collect, as well as creates strong partnerships with our seed growers, farmers, and processing partners. We are working toward being able to measure the environmental impact at the farm through processing as well as the product level. Through improved traceability capabilities,

95

Benson Hill will also continue to seek out and leverage third-party certifications, such as the Non-GMO Project Verified certification, meeting both food manufacturer and consumer demands.

•

Recruit and retain purpose-driven talent. Current research suggests employees are increasingly interested in working for companies that have an integrated ESG mission and purpose. Benson Hill has developed processes and internal programs, such as employee-led committees, that promote working together and re-thinking how we do business within our company, with our partners, and across the supply chain. We are working to develop teams that are grounded in a spirit of diversity, equality, and inclusion, and encouraged to think more innovatively, boldly, and transparently. Our goal is a workplace that is not just productive, but one of mutual respect and an environment for team members to continuously develop as professionals.

In order to measure and accelerate our ongoing work around ESG impacts, we have a highly experienced ESG team that is working to formalize our structure and focus in 2021 and beyond. With a depth of knowledge in food retail, distribution, agricultural production, and government relations, our sustainability team is committed to cultivating sustainability within the food system. As an organization, we are committed to continuous improvement. The team will focus on advancing our strategy, policies, and practices and is committed to quantifying our environmental, social impact, and corporate governance efforts both within Benson Hill and in our work across the value chain.

Benson Hill’s ESG strategy and business objectives will continue to progress and evolve based on industry shifts and stakeholders' needs. We strongly believe our long-term profitability goals and our ESG strategy are mutually inclusive concepts, and are aligned with the following UN Sustainable Development Goals:

Business Segments, Growth Strategies, and Products

Benson Hill’s business is comprised of two segments — our Ingredients Business and our Fresh Business — which aim to combine our seed innovation through our CropOS® platform with critical infrastructure capabilities and best practices in the field to develop and commercialize differentiated products. We are currently developing a diversified portfolio spanning four key markets — plant-based foods, animal feed, vegetable oils, and fresh produce. For each product, our research and development efforts are focused on quality-centric traits, such as nutrient density, flavor, ingredient functionality, and sustainability, as well as yield potential and agronomic improvements.

Our planned portfolio of products across our targeted markets are as follows:

96

Integral to our go-to-market strategy are our infrastructure capabilities along with our partnerships across the supply chain. Unlike traditional agriculture-focused crop improvement companies that focus their impact on development of the seed and sale to the farmer, we are building an integrated supply chain through directly owned or controlled assets, tolling agreements, and strategic partnerships in order to provide adequate capacity and influence throughout the food and ingredient supply chain. We strongly believe this approach ensures the integrity of our products, and enables the efficient development, commercialization, and scaling of our product offerings. Importantly, it also enables a more direct and intimate relationship with those who will be realizing the benefits of those products — i.e. retailers, consumer packaged goods (CPG) companies, and consumers — which informs our product development.

Our partnerships with farmers are an essential part of our supply chain. Within the traditional agriculture industry supply chain, farmers typically sell to elevators or processors who operate a high volume/​low margin business to store commodity crops and convert them into largely animal feed and industrial products. Our strategy is to partner with farmers who grow our seeds using appropriate agronomic and identity preservation practices and, in turn, we purchase their harvest for ultimate sale to an end-user customer. We believe structuring the relationship in this way will better allow us to drive best practices for on-farm sustainability, ensure traceability of our products, and help create new markets and profitable opportunities for farmers.

Once we obtain the harvest from the farmer, we secure the processing and distribution capacity that is appropriate for the product to meet our customers where they are. CPG and retailer customers sell directly to consumers. We share their focus on the end consumer in order to better align incentives, focus product development, and deliver our products through a channel that best serves their supply chain with the high quality standards, traceability, and sustainability data that consumers desire.

Our growth strategy for our business segments is based on a replicable process that we believe will enable us to remain at the forefront of food and agriculture innovation.

•

Step 1: Create the foundation — At this initial step, we are focused on market entry, selling non-proprietary products to processors, food and ingredient companies, animal feed customers, and retailers. We use this time to build relationship across the value chain and invest in the data to inform our CropOS® platform with low capital investment.

•

Step 2: Integrated route to market — In this step, we introduce our proprietary products in the channel to prove the product concept, scale, ensure traceability, and catalyze customer demand for our differentiated products. This stage includes the use of third party processors and exploring capital investment and strategic partnerships that can further expand production capacities.

•

Step 3: Broad adoption — We believe this will be the most asset-light step of our strategy where we intend to focus on maximizing the benefit and scale of our proprietary products by building partnerships and licensing relationships for our products. In this step, it is envisioned that we will grow beyond our proving ground acreage and increase commercial and supply chain efficiencies by leveraging others’ existing infrastructure. We intend for these commercial agreements to maintain product traceability and measure environmental impact.

As part of our growth strategy, we also intend to pursue selective merger and acquisition opportunities to expand our capabilities and grow our industry and geographic footprint. Our management has a demonstrated track record of execution and integration for strategic mergers and acquisitions, including Dakota Ingredients and J&J Family of Farms.

Ingredients Business Segment

Our Ingredients Business is focused on enhancing soy and yellow pea ingredients for multiple protein markets, including the fast-growing plant-based meat substitute market. This market is growing rapidly and is expected to exceed $140 billion over the next ten years, according to Kearney industry research. According to the Good Food Institute, in the U.S. alone, plant-based retail sales grew over 27 percent over the past year to reach a total of $7 billion. Our targeted end markets for the Ingredients Business include plant-based foods, animal feed, cooking oil, pet food, and aquaculture. Our target customer base includes ingredient companies, CPG companies, animal production and feed companies, food-service operations, and grocery retail.

Soy Ingredient Products

We are in Step 2 of our growth playbook for our soy ingredients business, and are currently working to develop and commercialize a portfolio of proprietary soy products targeted toward the plant-based food, animal feed, and cooking oil markets, which include the following:

•

Our plant-based protein ingredient derived from UHP soybeans for application in human food markets targeted to be commercialized in 2022.

•

Bright Day™ high protein and low anti-nutrient soybean meal for animal feed and aquaculture markets targeted to launch in 2021.

•

Veri™ high oleic cooking oil that was launched in 2020.

The foundation of our soybean genetics derives from certain assets we acquired in 2019 from Schillinger Genetics, Inc., an Iowa-based company that used traditional breeding methods for over 20 years to develop high-protein and specialty, non-GMO soybean varieties. We use our CropOS® platform to develop and test our soybean varieties, help identify the best environments for protein production, and advance our breeding pipeline.

As part of our soy ingredient business, we partner with growers across the Midwest to plant our eMerge Genetics® seeds for ingredient production, enabling local growers to tap into price premiums for food- and feed-grade, identity-preserved, non-GMO soybeans needed by the food and feed markets.

In addition, we also partner with processors as needed to obtain the crushing, processing, and refining capacity for our growing business in soy ingredients. In 2020, we entered into a commercial relationship with Rose Acre Farms in Indiana in order to help scale our production of protein ingredients. Over the next several years, we intend to engage in further capital investments to add capacity for additional demand.

•

Plant-Based Food Market: Soy, specifically soy protein concentrate (SPC), is the number one protein ingredient used in plant-based meat applications. This ingredient is largely made through the processing of defatted soy flour — which is costly and water- and energy-intensive. Our UHP soybean product is designed to provide a functional, scalable, and cost-effective solution to SPC in plant-based meat applications. By leveraging the plant’s genetic diversity, we have optimized the protein content of our soybeans to a level that we believe effectively disintermediates a processing step necessary to arrive at a protein level that is suitable for plant-based meat applications. We plan to market this proprietary ingredient as a sustainable alternative to SPC for plant-based meat applications.

•

Animal Feed: Soybean meal is an ideal protein source for swine, poultry, and fish due to its availability, cost, high protein content, and balanced amino acid profile. According to the Michigan State University Extension, over 90% of soybeans produced in the United States are fed to animals. However, its use is restricted because — like many plant proteins — soybean meal has a high concentration of anti-nutritional compounds (ANCs), including oligosaccharides such as raffinose and stachyose that can have a negative effect on protein digestibility, leading to low energy values, poor metabolism, and excessive secretion impacting water quality in aquaculture systems. Apart from antinutritional factors, the steady decline in protein content of soy — an unintended consequence of breeding primarily for yield and other agronomic traits — has rendered soy meal a continually less valuable feed ingredient.

Our Bright Day™ pipeline of soy products for animal feed includes a high protein soymeal that is low in anti-nutrients and a low-cost, sustainable SPC substitute. As we build this portfolio of products, we intend to devote additional R&D resources toward developing future generations of products with increased protein compositions and lower anti-nutrient qualities in order to improve the quality of feed ingredients options available to formulators that seek to prioritize animal health, sustainability, and profitability of their operations.

•

Vegetable Oils: According to a Research and Markets report, the global vegetable oil market was estimated at approximately $230 billion in 2020, comprised of predominately four crops (palm, soy, rapeseed, and sunflower). According to an Allied Marked Research report, by 2022, the global cooking oil and fats market is forecasted to grow to $65 billion globally and includes both frying and baking applications, as well as shelf-stable products like salad dressings.

98

Recognizing these trends, we recently launched Veri™, a non-GMO, high-heat soy cooking oil that is rich with heart-healthy omega-9 fatty acids.(1) Our Veri™ brand soy oil is high in oleic acid and low in linoleic acid with an optimized fatty acid profile from both a human consumption and food service operations standpoint. In our pipeline of products, we are also developing a vegetable oil product that is intended to be a sustainable vegetable oil with omega-9 fatty acids.

Yellow Pea Ingredients

We are in Step 1 of our growth playbook for yellow pea, and over the medium-term, we expect to commercialize proprietary yellow pea products through our existing supply chain infrastructure.

Despite being the fastest growing protein ingredient for plant-based meats, yellow pea has received comparatively little genomic innovation to date. The pea-based protein ingredient primarily used today by many plant-based meat companies, such as Beyond Meat, is pea protein isolate (PPI). The PPI production process, similar to SPC, is expensive as well as water- and energy- intensive; however, such processing is necessary to concentrate protein to higher levels and help ameliorate native off-putting flavors of pea.

We have sequenced and assembled a reference genome for yellow pea — a high resolution “genomic map” — that, in combination with our CropOS® platform, is enabling us to accelerate our yellow pea breeding program. As a result, we believe we will develop differentiated varieties of yellow pea for commercialization in the medium-term. We are working on a pipeline of products that has the potential to significantly reduce off-flavors, increase the protein content of the plant, and ultimately reduce or displace the need for expensive, water- and energy-intensive processing steps typically required for ingredients used in plant-based alternatives. We have several yellow pea product candidates in development which we expect to bring to market in the medium- to long-term, including texturized pea protein, a next-generation pea protein ingredient product, and premium yellow pea protein concentrate.

Our subsidiary Dakota Dry Beans, Inc. (doing business as “Dakota Ingredients”), an upper Midwest-based yellow pea processor, has an established channel with commodity pea protein concentrate, split peas, pea flour and pea fiber. We have expanded and upgraded the capabilities of Dakota Ingredients to better serve the pet and human food markets. Through our elite grower program and integrated production capabilities, the operation can now test premium yellow pea varieties and supply ingredients that are traceable and meet certain food-grade, kosher, and non-GMO certification standards. We are currently engaged with pet and human food ingredient customers interested in the next generation of yellow pea protein ingredients and are working to establish sustainability best practices across our supply chain.

Fresh Business Segment

Our Fresh Business is focused on combining the breeding power of our CropOS® platform over the long-term with the extensive grower base, distribution network, and retail relationships of our wholly-owned subsidiary, J&J Family of Farms, a field produce company. With this combination, we believe our Fresh Business is well-positioned over the coming years to execute on the development and ultimately the commercialization of differentiated produce and “functional foods.” This business segment is in Step 1 of our growth playbook today as we operate our J&J Family of Farms subsidiary and prepare to serve this large market opportunity long-term. While we do not have any proprietary genetics to differentiate fresh produce products on the market today, we are making investments in this area and intend to develop a pipeline of product candidates. Additionally, we are making strategic investments in our supply chain to deliver premium product to our customers, including an investment in a new facility and growing operation in Vero Beach, Florida, which is scheduled to be completed by the end of 2021. This new facility is intended to expand J&J Family of Farms’ capacity to grow fresh produce, execute research and development, and conduct seed variety trials. We have made sustainability a key design element at this new operation, including investing in infrastructure to support drip irrigation and precision nutrient and crop protection application.

Supportive but not conclusive scientific evidence suggests that daily consumption of about 11∕2 tablespoons (20 grams) of oils containing high levels of oleic acid, when replaced for fats and oils higher in saturated fat, may reduce the risk of coronary heart disease. To achieve this possible benefit, oleic acid-containing oils should not increase the total number of calories you eat in a day. One serving of high oleic soybean oil provides 10 grams of oleic acid (which is 11 grams of monounsaturated fatty acid).

99

J&J Family of Farms is a Florida-based leading national grower, packer and shipper of field-grown vegetables and fruits and value-added produce on over 11,000 acres of farmland under management and multiple packing and cooling facilities. In addition to being prepared to grow a significant volume of sweet and hot peppers, yellow squash, zucchini, cucumbers, eggplant, and melon for commercial distribution, J&J Family of Farms has long-standing retail, grocer, and food service relationships and is actively working on new grower relationships to further expand capacity to deliver premium quality produce throughout the year to retail and food service customers.

Competitive Strengths

Our competitive strengths are rooted in a combination of technology and product innovation with our go-to-market strategy, including our willingness to vertically integrate to offer differentiated ingredient solutions and sustainability throughout the supply chain.

We believe the following strengths differentiate us and position us well to develop and commercialize high-value and innovative products, and to help bridge a historical divide between farmer and consumer demands in our commodity-focused food system.

•

Innovative product development process intensely focused on consumer needs.   Our most important competitive strength is our product development process that starts with the consumer in mind. This approach differs from traditional agricultural companies, and it requires different data sets and core competencies to develop quality-focused traits and characteristics related to nutrient density, flavor, and ingredient functionality. Integrating food science data on end-products, consumer sensory panel data, and supply chain insights to front-end product design is not traditionally a focus of the seed industry and leveraging best-in-class technological solutions to tap into the natural genetic diversity of plants as a source of end-product differentiation is not traditionally a focus of the ingredient and CPG industries.

•

Leverage proprietary technologies that we believe will enable us to create products faster and for less cost.   CropOS® is our proprietary platform that we believe will allow us to accelerate plant breeding, genome editing, and the product optimization processes. Front-end prediction and in silico simulation within the CropOS® platform has the potential to save significant time and cost in the product development process. Outside of the prediction and in silico simulation, our proprietary CRISPR gene editing technology and capabilities as well as our speed breeding process will enable rapid product development and testing.

•

Current products and pipeline focused on large, rapidly expanding markets.   We are currently working to develop and commercialize a diverse product portfolio spanning four target markets — plant-based foods, animal feed, vegetable oils and fresh produce. These markets are large and growing rapidly as consumers become more concerned with health and sustainability. The total U.S. fruit and vegetable market is projected to reach approximately $1.1 trillion by 2025 according to Grand View Research Inc., and the global cooking oil and fats market is forecasted to reach approximately $65 billion by 2022 according to Allied Market Research.

•

Crop and market-agnostic approach we believe will enable us to innovate at the pace of consumer trends.   While the four target markets mentioned above are our focus today, we believe our technologies and business model can be applied to different crops and markets, enabling a ‘rinse and repeat’ approach to quickly capitalize on emerging food trends. We believe that the CropOS® platform has the potential to be leveraged as an iterative, crop-agnostic development tool to aim at interesting or emerging markets

•

Integrated go-to-market approach, enabling us to reduce adoption risk, accelerate time to market, and increase margin capture.   We are building an integrated supply chain through directly-owned assets, tolling agreements, and strategic partnerships in order to provide adequate capacity and influence throughout the food and ingredient supply chain. We believe this approach enables accelerated product deployment, improved value-capture, and that more direct relationships with our end-customers, such as plant-based CPG companies and retailers, will provide for long-term, successful and collaborative relationships over many product life cycles.

•

World-class management team with deep industry expertise. Our senior leadership team has more than 300 years of collective experience in the agri-food fields, including agricultural supply chains, research and product development, and commercial operations. Members of our senior team have managed billions of dollars of revenue and cost at large multinational corporations, and have previously worked at well-known technology and seed, agri-business, food and fresh produce companies including Bayer Crop Science (formerly Monsanto), Solae, Kellogg’s, Conagra, Bunge, TreeHouse Foods, Mastronardi Produce, and Nestle Purina.

We plan to continue to build our supply chain infrastructure in instances where access to capacity and customers are limited, when accelerated time to market is imperative, or opportunistically as our business grows in size and scope. We intend to invest appropriately to establish the integrated model to prove product concepts, meet our customers where they are, and catalyze demand for our products.

Competitors

We believe that our technology platform coupled with our integrated go-to-market approach is unique to Benson Hill and sets us apart from others in the agriculture and food markets, but we do compete with others in certain areas of our business. We compete with seeds and trait companies as well as smaller biotechnology and ag-tech companies, particularly for grower contracting and access to acres. Key competitors in this space include Bayer, Corteva, Syngenta, and Pairwise. As our ingredient and fresh products are commercialized, we will compete more with food and feed ingredient companies and fresh produce companies, and key competitors in this space include ADM, Roquette, Cargill, and Lipman. Advancements in gene editing, digital agriculture, data science, and artificial intelligence may enable disruptive technology that could alter the competitive landscape for food and agriculture.

Intellectual Property

Our success depends in part on our ability to obtain and maintain intellectual property and proprietary protection for our product candidates and technology related to our business, defend and enforce our intellectual property rights, in particular, our patent rights, preserve the confidentiality of our trade secrets, and operate without infringing valid and enforceable intellectual property rights of others. We seek to protect our proprietary position by, among other things, licensing and filing United States and certain non-U.S. patents and patent applications related to our technology, products and product candidates, and improvements that are important to the development of our business, where patent protection is available. We also rely on trade secrets and/or contractual provisions to develop and maintain our proprietary position and protect aspects of our business that are not amenable to, or that we do not consider appropriate for, patent protection. We seek to protect our proprietary technologies, in part, by confidentiality agreements with our employees, consultants, scientific advisors, and contractors. Notwithstanding these efforts, we cannot be sure that patents will be granted with respect to any patent applications we have licensed or filed or may license or file in the future, and we cannot be sure that any patents we have licensed or patents that may be licensed or granted to us in the future will not be challenged, invalidated, or circumvented or that such patents will be commercially useful in protecting our product candidates and technology. Moreover, trade secrets can be difficult to protect. While we have confidence in the measures we take to protect and preserve our trade secrets, such measures can be breached, and we may not have adequate remedies for any such breach. In addition, our trade secrets may otherwise become known or be independently discovered by competitors. For more information regarding the risks related to our intellectual property, please see “Risk Factors — Risks Relating to Benson Hill’s Business and Industry — Risks Relating to Intellectual Property.”

As of July 30 2021, we have filed patents and patent applications in approximately 21 distinct non-plant germplasm patent families, including approximately 13 granted U.S. patents, 14 pending U.S. patent applications, 3 granted non-U.S. patents, and 105 pending Patent Cooperation Treaty (PCT) and non-U.S. patent applications. Within this portfolio, approximately 81 patents and patent applications relate to the trait genes of plants and 21 relate to enabling technology (including gene editing-focused patents and patent applications). The Company also has approximately 47 granted and 49 pending soybean patents. In addition to these patents and patent applications filed by Benson Hill, we also hold licenses from other parties related to certain products and activities.

101

We anticipate that our currently granted U.S. and non-U.S. patents will expire approximately between 2024 and 2038, subject to potential extensions. Individual patent terms extend for varying periods of time, depending upon the date of filing of the patent application, the date of patent issuance, and the legal term of patents in the countries in which they are obtained. In most countries in which patent applications are filed, including the United States, the patent term is 20 years from the date of filing of the first non-provisional application to which priority is claimed. Under certain circumstances, a patent term can be extended. For example, in the United States, a patent’s term may be lengthened by patent term adjustment, which compensates a patentee for administrative delays by the U.S. Patent and Trademark Office in reviewing and granting a patent or may be shortened if a patent is terminally disclaimed over an earlier-filed patent. However, the actual protection afforded by a patent varies on a product-by-product basis, from country-to-country, and depends upon many factors, including the type of patent, the scope of its coverage, the availability of legal remedies in a particular country, and the validity and enforceability of the patent.

As of July 30, 2021, we had 22 U.S. trademarks and 8 pending U.S. trademark applications, and we had 79 registered non-U.S. trademarks and 5 pending non-U.S. trademark applications.

Research and Development

As of June 30, 2021, we had approximately 135 employees dedicated to our product and platform development. This team has technical expertise in data science, machine learning software, genome engineering, molecular biology, biochemistry, genetics and genetic engineering, plant physiology, and plant breeding. The activities of this team are conducted principally at our St. Louis, Missouri facilities. We have made, and will continue to make, substantial investments in this capability. Our research and development expenses were $15.9 million for the six months ended June 30, 2021 and $29.5 million, $24.8 million and $13.4 million for the years ended December 31, 2020, 2019 and 2018, respectively.

Employees

As of June 30, 2021, we employed approximately 330 full-time employees, of whom over 135 hold an advanced degree and approximately 40% of whom are involved in product and platform development.

Facilities

Our principal executive office is a leased office and research and development facility located at 1001 N. Warson Rd., St. Louis, Missouri 63132. We lease certain greenhouse facilities in Earth City, Missouri, as well as research and development facilities at the Donald Danforth Plant Science Center located in St. Louis, Missouri. In addition, we are currently constructing an approximately 47,000 square-foot controlled environment research facility building located in St. Louis, Missouri. This facility will be leased and is expected to be operational by the end of 2021.

Across our subsidiaries, J&J Family of Farms leases an office, packaging, and distribution facility in Westlake, Florida, and owns a packaging and distribution facility in Adel, Georgia. In addition, we are in the process of building out new farmland on approximately 1,000 acres of owned agricultural land near Vero Beach, Florida, which includes the construction of a new packaging, distribution, and warehouse facility, as well as office space and research and development operations. The new facility is a budgeted investment of approximately $26 to $27 million in our strategic infrastructure growth designed to expand our capacity to grow fresh produce, engage in commercial distribution and conduct seed variety trials. As of June 30, 2021, we have spent approximately $16.1 million toward the project. Benson Hill is overseeing the construction of the facility and is working with various contractors and sub-contractors to complete the work. This new facility will be owned and is scheduled to be completed by the end of 2021, at which time our current operations at our Westlake, Florida and Adel, Georgia facilities will be consolidated in the new Vero Beach, Florida facility.

Dakota Ingredients owns processing facilities in Crary, North Dakota, Devils Lake, North Dakota, and Lansford, North Dakota, as well as a leased office facility in Grand Forks, North Dakota.

We believe that our facilities are sufficient to meet our current needs and that suitable additional space will be available as and when needed.

102

Regulatory

We are subject to laws and regulations in the jurisdictions in which we operate. This includes laws and regulations governing biotechnology and food companies related to the development, approval, manufacturing, import, marketing, and sale of our products.

Regulation of Plant Biotechnology Products

The three primary agencies with responsibility for regulation of plant biotechnology products in the United States are the U.S. Department of Agriculture’s (“USDA”) Animal and Plant Health Inspection Services (“APHIS”), the U.S. Environmental Protection Agency (“EPA”), and the U.S. Food and Drug Administration (“FDA”). APHIS regulates plant biotechnology products to ensure that they do not pose a plant pest risk under the Plant Protection Act. EPA regulates pesticides (including plant-incorporated protectants) pursuant to the Federal Insecticide, Fungicide, and Rodenticide Act (“FIFRA”). FDA regulates food and animal feed under the Federal Food, Drug, and Cosmetic Act (“FDCA”).

Plant gene editing uses relatively new technology and the regulatory landscape continues to evolve in this area. Under the USDA’s recently revised regulations, certain categories of our products currently in development using gene editing may be exempt from certain regulations related to genetic engineering under the Plant Protection Act because they could otherwise have been developed through conventional breeding techniques, which may include gene edited soybeans or yellow peas. Other plant biotechnology products currently in development may be subject to certain regulations related to genetic engineering under the Plant Protection Act in the future. FDA offers a voluntary consultation process to determine whether foods derived from plant biotechnology products would require regulatory review and approval before marketing such products.

Other countries also have laws and regulations that apply to plant biotechnology products. The regulatory landscape around gene edited plant biotechnology products varies in each country and continues to evolve.

Regulation of Food and Ingredient Products

We are also subject to laws and regulations administered by various federal, state and local government agencies in the United States, such as FDA, the Federal Trade Commission, the EPA, the Occupational Safety and Health Administration, and the USDA, related to the processing, packaging, distribution, sale, marketing, labeling, quality, safety, and transportation of our products, as well as our occupational safety and health practices.

Among other things, the facilities in which our products are grown, packed or processed may be required to register with the FDA, and comply with regulatory schemes including the Food Safety Modernization Act (“FSMA”), among other laws and regulations implemented by the FDA, the USDA, and other regulators. We are also subject to parallel state and local food safety regulation, including registration and licensing requirements for our facilities, enforcement of standards and label registration for our products and facilities by state and local health agencies, and regulation of our trade practices in connection with selling our products. We are also subject to labor and employment laws, laws governing advertising, privacy laws, safety regulations and other laws, including consumer protection regulations that regulate retailers or govern the promotion and sale of merchandise.

Legal Proceedings

We currently are not a party to any material litigation or other material legal proceedings. From time to time, we may be subject to legal proceedings and claims in the ordinary course of business.

103

Other Information

We were incorporated in North Carolina on June 28, 2012. On June 1, 2015, we converted to a Delaware corporation. Our principal executive offices are located at 1001 N. Warson Rd., St. Louis, Missouri 63132, and our telephone number is 314-222-8218. We also maintain a website at www.bensonhill.com. The information contained in, or that can be accessed through, our website is not part of this proxy statement/prospectus.

EXECUTIVE AND DIRECTOR COMPENSATION OF BENSON HILL

This section provides an overview of the Company’s executive compensation programs, including a narrative description of the material factors necessary to understand the information disclosed in the summary compensation table below.

For the year ended December 31, 2020, the Company’s named executive officers (“Named Executive Officers” or “NEOs”) were:

•

Matthew Crisp, President and Chief Executive Officer;

•

Christopher Wilkins, Former Chief Operating Officer; and

•

Michael Wainscott, Former Executive Vice President, Corporate Development.

NEO Transitions

On March 2, 2021, Mr. Wainscott voluntarily separated from his position as Executive Vice President, Corporate Development. He was not entitled to any payments, other than accrued, unpaid benefits, in connection with his separation.

On June 14, 2021, Mr. Wilkins voluntarily separated from his position as Chief Operating Officer. In addition to his accrued, unpaid benefits, Mr. Wilkins may be entitled to certain payments in connection with his separation pursuant to his Loyalty Agreement (as summarized below under the heading “Agreements with our NEOs”).

Our Compensation Program

The objective of the Company’s compensation program is to provide a total compensation package to each NEO that will enable the Company to attract, motivate and retain outstanding individuals, align the interests of our executive team with those of our stockholders, encourage individual and collective contributions to the successful execution of our short- and long-term business strategies and reward NEOs for performance. The board of directors of the Company has historically determined the compensation for the NEOs.

For 2020, the compensation program for the NEOs consisted of base salary and short-term incentive compensation, each as described below:

•

Base Salary.    Base salary is paid to attract and retain qualified talent and is set at a level that is commensurate with the executive’s duties and authorities, contributions, prior experience and sustained performance. In October 2020, Mr. Wainscott’s base salary was increased from $320,851 to $340,851, to reflect a market adjustment. Messrs. Crisp and Wilkins’ base salaries for 2020 remained unchanged from 2019.

•

Short-Term Cash Incentives.    Our NEOs are eligible for an annual cash bonus under our Annual Incentive Plan. For 2020, Messrs. Crisp, Wilkins and Wainscott had target bonus opportunities equal to 30%, 25% and 25% of each NEO’s base salary, respectively. The amount of each NEO’s annual cash bonus payable pursuant to the Annual Incentive Plan in 2020 was based on a mix of quantitative and qualitative individual and Company performance metrics, set forth below, with each NEO’s achievement of such performance metrics and the final annual cash bonus amounts payable being determined in the sole discretion of our board of directors:

•

Financial-related goals (weighted 30%), including improvement of the Company’s EBITDA, capital formation, and expansion of venture debt;

•

Operational-related goals (weighted 50%), including the launch of a key product line, execution of the Company’s research and development pipeline, and development of CropOS, a data analytics platform; and

•

Corporate functionality goals (weighted 20%), including the establishment of a formal Project Management Office and general and administrative best practices.

105

•

Long Term Cash Incentives.   Our NEOs did not receive grants of long-term equity incentive awards pursuant to the Benson Hill Biosystems, Inc. 2012 Stock Incentive Plan (the “SIP”) in 2020. Historically, we have made stock option awards to our NEOs subject to time-based vesting, performance-based vesting or both, as reflected in our Outstanding Equity Awards at 2020 Fiscal Year-End table below.

Employee Benefits

Our NEOs are generally eligible to participate in our health and welfare, retirement and other employee benefit programs on the same basis as other employees, subject to applicable law. We maintain a 401(k) plan for eligible employees. Under the 401(k) plan, eligible employees may elect to contribute a portion of their eligible compensation as pre-tax or Roth deferrals or on an after-tax basis in accordance with the limitations imposed under the Internal Revenue Code of 1986, as amended (the “Code”). We match 100% of each dollar contributed by a participant, up to the first 3% of eligible 401(k) compensation, and 50% of each dollar contributed between 3% and 5% of the participant’s eligible 401(k) compensation, subject to limitations imposed under the Code. We may also make discretionary matching contributions up to 4% of a participant’s eligible 401(k) compensation. The Company did not maintain any executive-specific benefit or perquisite programs in 2020.

Agreements with our NEOs

Mr. Crisp is an at-will employee and is not a party to an offer letter or employment agreement with the Company.

Messrs. Crisp and Wilkins are party to the Company’s general form of Loyalty Agreement used for Company employees, which provides for one-year salary continuation upon an employee’s separation if, in our sole discretion, we elect to bind the employee to a one-year post-employment non-competition covenant (“Non-Compete Provision”). The Loyalty Agreement also provides for certain restrictive covenants, including a confidentiality, IP assignment, and a during employment and one-year post-termination non-solicitation of employees, consultants or customers provision. Mr. Wainscott was party to the Company’s 2018 general form of Loyalty Agreement, which generally provided for the same terms as the 2021 Loyalty Agreement, other than the Non-Compete Provision.

Messrs. Wilkins and Wainscott were each party to offer letters, dated March 29, 2019 and October 2, 2020, respectively, with the Company that terminated in connection with each NEO’s voluntary separation from the Company, described above under “NEO Transitions.”

106

Prior to the completion of the Business Combination, New Benson Hill may enter into employment with certain of its key executive officers, including the Chief Executive Officer. There is at this time no assurances that any such agreements with New Benson Hill will be executed, and if so, what the terms and conditions of any such agreements would be.

Potential Payments Upon Termination or Change in Control

As of December 31, 2020, Messrs. Crisp and Wilkins were eligible for salary continuation payments and upon a separation where the Company chose to elect to bind the NEO to a one-year post-termination non-compete for Messrs. Crisp and Wilkins (as summarized above under the heading “Agreements with our NEOs”). In addition, the Company maintained an informal severance policy for all employees, including our NEOs, who were involuntarily terminated due to a job elimination, pursuant to which our NEOs would be eligible to receive severance benefits equal to four weeks base salary in exchange for executing a general release of claims. As of December 31, 2020, Mr. Wainscott, pursuant to his October 2, 2020 offer letter, would have been eligible for 90 days of salary continuation if terminated by the Company without cause, after entering into a general release of claims. Mr. Wainscott was not entitled to any salary continuation in connection with his voluntary separation from the Company on March 2, 2021.

In addition, pursuant to their stock option award agreements, in the event an NEO’s employment is involuntary terminated without cause (as defined under the SIP) within one year of a change in control of the Company, any outstanding stock options held by our NEOs would become fully vested and exercisable.

Post-Business Combination Company Executive Compensation

Following the completion of the Business Combination, New Benson Hill intends to develop an executive compensation program that is designed to align compensation with New Benson Hill’s business objectives and the creation of stockholder value, while enabling New Benson Hill to attract, motivate and retain individuals who contribute to the long-term success of New Benson Hill. Decisions on the executive compensation program will be made by the compensation committee of the board of directors.

Director Compensation

The Company’s board of directors sets non-employee director compensation which is designed to provide competitive compensation necessary to attract and retain high quality non-employee directors and to encourage ownership of Company stock to further align their interests with those of our stockholders. Each non-employee director of the Company is eligible to receive the following compensation:

•

An annual cash retainer of $60,000; and

•

An initial stock option award consisting of 160,000 underlying shares of stock, which vests ratably on a quarterly basis over two years.

BENSON HILL’S MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the financial condition and results of operations of Benson Hill, Inc. and its subsidiaries should be read together with the section of this proxy statement/prospectus entitled “Selected Historical Consolidated Financial Information of Benson Hill,” the unaudited condensed consolidated financial statements as of June 30, 2021 and for the three and six month periods ended June 30, 2020 and 2021, and the audited consolidated financial statements, together with related notes thereto, included elsewhere in this proxy statement/prospectus. The discussion and analysis should also be read together with the section of this proxy statement/prospectus entitled “Information About Benson Hill” and the unaudited pro forma condensed combined financial information as of June 30, 2021 and for the six months ended June 30, 2021 and the year ended December 31, 2020 (in the section of this proxy statement/​prospectus entitled “Unaudited Pro Forma Combined Financial Information”). The following discussion contains forward-looking statements that involve risks, uncertainties and assumptions. See the section entitled “Forward-Looking Statements; Market, Ranking and Other Industry Data.” Actual results and timing of selected events may differ materially from those anticipated in the forward-looking statements as a result of various factors, including those set forth under the section entitled “Risk Factors — Risks Related to Benson Hill’s Business and Industry” or elsewhere in this proxy statement/prospectus.

Overview

Benson Hill, Inc. (together with its subsidiaries prior to the consummation of the merger, is referred to in this section as the “Company”, “Benson Hill”, “we” “us” or “our”) was founded in 2012. We are headquartered in St. Louis, Missouri, where the majority of our research and development activities are managed, but also supply fresh produce through packing, distribution, and growing locations in the southeastern states of the United States, and process dry peas in North Dakota, which we sell throughout North America.

We are a values-driven food technology company with a vision to build a healthier and happier world by unlocking nature’s genetic diversity with our food innovation engine. Our purpose is to catalyze and broadly empower innovation from plant to plate so great tasting, healthy, affordable, and sustainable food choices are available to everyone. We combine cutting-edge technology with an innovative business approach to bring product innovations to customers and consumers. Our CropOS® technology platform uniquely combines data science, plant science, and food science to create innovative food, ingredients, and feed products — starting with a better seed. Our go-to-market strategy consists of building an integrated supply chain to catalyze demand for our proprietary products, which we believe will allow us to establish partnerships and licensing arrangements to drive broad adoption. We believe this approach will allow us not only to ensure the integrity and traceability of our products, but also to measure the positive environmental impact created by our innovations.

Today, our business is comprised of two segments — our Ingredients Business and our Fresh Business. Our Ingredients Business is currently focused on enhancing soybean and yellow pea products, including soy-based vegetable oils, animal feed, and ultra high protein (“UHP”) soybeans that have the potential to reduce costly water- and energy-intensive processing associated with producing protein concentrates and isolates for the food and feed markets, alleviating supply constraints to help bring plant-based proteins to scale. Our Fresh Business is being built to serve the growing consumer interest in the convergence between food and health. Today this segment includes our subsidiary, J&J Produce, Inc., where we sell fresh produce products to major retail and food service customers. We have initiated the establishment of research and development operations where we intend to use our CropOS® innovation engine platform to unlock flavor, nutrition, and sustainability benefits in fresh produce over the long-term.

COVID-19

As a result of the COVID-19 pandemic, governmental authorities have implemented numerous and rapidly evolving measures to try to contain the virus, such as travel bans and restrictions, limits on gatherings, quarantines, shelter-in-place orders, and business shutdowns. In response to the COVID-19 pandemic and in accordance with governmental orders, we have also modified our business practices and implemented proactive measures to protect the health and safety of employees, including restricting employee travel,

112

requiring, at times, remote work arrangements for non-laboratory employees, implementing social distancing, and enhanced sanitary measures in our headquarters, and cancelling attendance at events and conferences. Many of the suppliers, vendors, and service providers on whom we rely on have made similar modifications. To date, with the exception of us modifying our physical business practices, including lower travel, and delays in the receipt of certain laboratory supplies and the performance of related services, we have not experienced a material impact on business operations from the effects of COVID-19. There is no certainty measures implemented by government authorities will be sufficient to mitigate the risks posed by, or the impacts and disruptions of, the COVID-19 pandemic.

Business Combination and Public Company Costs

On May 8, 2021, Benson Hill, STPC and Merger Sub entered into the merger agreement pursuant to which Benson Hill will be merged with and into Merger Sub, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC. The transaction will provide the combined entity New Benson Hill with approximately $625 million of gross proceeds, including the fully committed private placement of 22.5 million shares of Class A Common Stock of STPC at $10.00 per share pursuant to the PIPE Investment. Benson Hill will be deemed the accounting predecessor and the combined entity will be the successor registrant with the SEC, meaning that Benson Hill’s consolidated financial statements for previous periods will be disclosed in the New Benson Hill’s (formerly STPC’s) future periodic reports filed with the SEC.

While the legal acquirer in the merger agreement is STPC, for financial accounting and reporting purposes under GAAP, Benson Hill will be the accounting acquirer and the merger will be accounted for as a “reverse recapitalization.” A reverse recapitalization (i.e., a capital transaction involving the issuance of stock by STPC for the stock of Benson Hill) does not result in a new basis of accounting, and the consolidated financial statements of the combined entity represent the continuation of the consolidated financial statements of Benson Hill in many respects. Accordingly, the consolidated assets, liabilities and results of operations of Benson Hill will become the historical consolidated financial statements of the combined company New Benson Hill, and STPC’s assets, liabilities and results of operations will be consolidated with Benson Hill beginning on the acquisition date. Operations prior to the merger will be presented as those of Benson Hill in future reports. The net assets of STPC will be recognized at historical cost (which is expected to be consistent with carrying value), with no goodwill or other intangible assets recorded upon execution of the merger.

Upon consummation of the merger and the closing of the PIPE Investment, the most significant change in Benson Hill’s future reported financial position and results of operations is expected to be an estimated increase in cash and cash equivalents (as compared to Benson Hill’s condensed consolidated balance sheet at June 30, 2021) of approximately $144 million, assuming maximum stockholder redemptions of all 40.3 million shares of STPC Class A Common Stock, or approximately $546 million, assuming no redemptions, and, in each case, including $225 million in gross proceeds from the PIPE Investment by the PIPE Investors. Total direct and incremental transaction costs of STPC and Benson Hill are estimated at approximately $50.0 million, including the payment of deferred underwriting and other transaction fees of $14.1 million associated with STPC’s IPO. Underwriting and other transaction fees associated with the merger are estimated at $35.9 million, of which $28.9 million will be treated as a reduction from New Benson Hill’s additional paid-in capital and $7.0 million will be expensed. See the section entitled “Unaudited Pro Forma Combined Financial Information.”

As a consequence of the merger, Benson Hill will become the successor to an SEC-registered and NYSE-listed company which will require Benson Hill to hire additional personnel and implement procedures and processes to address public company regulatory requirements and customary practices. Benson Hill expects to incur additional annual expenses as a public company for, among other things, directors’ and officers’ liability insurance, director fees and additional internal and external accounting, legal and administrative resources, including increased audit and legal fees. The Company will be classified as an “emerging growth company”, as defined under the JOBS Act that was enacted on April 5, 2012. As a result, upon consummation of the merger, the Company will be provided certain disclosure and regulatory relief, provided by the SEC, as an “emerging growth company”.

Benson Hill’s future results of consolidated operations and financial position may not be comparable to historical results as a result of the merger.

113

Key Components of Statement of Operations

Revenue

The Company generates revenue from product sales, licensing fees associated with our proprietary technology platform and/or our intellectual property, and commissions earned on product sales.

Product sales consist primarily of sales of harvested produce, both farmed by us and purchased from growers in non-exclusive arrangements, sales of seed, and sales of processed yellow pea, soybean grain, soybean oil and soybean meal.

In addition to selling our owned farmed produce, we enter into consignment arrangements with produce growers of certain perishable products. In these arrangements, we act as an agent, earn a commission on the sale and report the revenue and cost of the product on a net basis.

Licensing fees consist of revenues earned by us in exchange for providing access to our proprietary cloud-based software platform, CropOS®, or through a right to use our proprietary intellectual property and/or patents for a specific period of time.

See Note 2 — Summary of Significant Accounting Policies in the notes to our audited consolidated financial statements for additional information on our revenue recognition.

Cost of Sales

The Company’s cost of sales includes all costs incurred to purchase, process and provide the product or services to the Company’s customers. For harvested produce farmed by us, this includes the direct cost of land preparation, seed, planting, growing, maintenance, packaging and distribution of product sales. For produce we purchase from growers in non-exclusive arrangements and, hence, do not farm, this cost includes the acquisition, warehousing, packaging and distribution of the purchased inventory.

The cost of sales on processed yellow pea, soybean grain, soybean oil and soybean meal includes the crush, refining and transportation costs necessary to prepare the product for sale.

Research and Development

Research and Development expenses consist of the costs of performing activities to discover and develop products and to advance our intellectual property. These costs consist primarily of employee-related expenses for personnel who research and develop our products, fees for contractors who support product development and breeding activities, expenses for trait validation, greenhouse and field trial expenses, purchasing material and supplies for our laboratories, licensing, information technology expenses, and other costs associated with operating our own laboratories.

Selling, General and Administrative Expenses

Selling, general and administrative expenses (“SG&A”) consist of employee-related expenses for selling our products, and costs related to business development to commercialize our product offerings along with our executive, legal, intellectual property, finance and human resources functions. SG&A expenses also include facility and information technology expenses not otherwise allocated to research and development or cost of sales, professional fees for auditing, tax and legal services, expenses associated with maintaining patents, and consulting costs.

Total Other Interest Expense (Income), Net

Total other expense (income), net consists primarily of interest expense per the terms of the Company’s various financing obligations, as further described in Note 8 — Leases and Note 12 — Debt in our audited consolidated financial statements, amortization of debt discount and commitment fees, remeasurements of our warrant liability and interest related to finance leases as reduced by interest earned on cash and marketable securities.

Results of Operations

Comparison of the Three Months Ended June 30, 2021 and 2020

The following table shows the amounts from our consolidated statements of operations for the periods presented:

​	Three Months Ended June 30,

Revenues

Revenues for the three months ended June 30, 2021 were $39.7 million, an increase of $8.7 million or 28%, as compared to the same period in 2020. In October 2020, we sold our barley operations, which contributed revenues of $4.0 million in the second quarter of 2020. Excluding the contribution from the barley operations, revenues for the three months ended June 30, 2021 increased $12.7 million or 47%. The increase was primarily driven by higher sales volumes of our proprietary high protein soybeans, soybean oil and soybean meal, of which commercialization efforts were initiated in the fourth quarter of 2020, higher average selling prices on yellow peas and higher sales volumes of fresh produce. Partially offsetting the increase was a decline in sales volumes of yellow peas, and lower average selling prices in fresh produce. Lower average selling prices in fresh produce were driven by higher regional and ex-US farm yields within the industry resulting in a higher supply versus demand.

Cost of sales and gross profit for the three months ended June 30, 2021 of $39.7 million and $(0.1) million, respectively, represented an increase in cost of sales of $13.0 million and a decrease in gross profit of $4.4 million as compared to the same period in 2020. In the second quarter of 2021 and 2020, there were certain items that are expected to be non-recurring. In the second quarter of 2021, we incurred $2.8 million of higher freight costs necessary to transport soybean seed stock from South America to our US-based operations. These costs were the result of us utilizing the South America growing season to prepare us for our US-based 2021 soybean harvest. Also, as noted previously, we sold our barley operations in October 2020, which contributed $0.6 million in gross profit in the second quarter of 2020.

Excluding the impact of items expected to be nonrecurring, as noted above, gross profit for the second quarter of 2021 was $2.8 million, which represents a decline of $1.0 million. The decrease in gross profit was primarily driven by lower royalties from legacy seed distribution contracts, losses generated on the commercial launch of proprietary soybean oil and soybean meal as higher average selling prices were more

115

than offset by start-up and other costs associated with the early-stage commercialization of these products, lower sales volumes of yellow peas, and lower average selling prices in fresh produce. Over time, we expect the royalties from legacy seed distribution contracts, which we acquired in conjunction with our acquisition of soybean germplasm in 2019, will decline as we elect to allow them to expire without renewal.

Research and Development Expenses

Research and development expenses for the three months ended June 30, 2021 of $8.8 million increased $1.7 million as compared to the same period in 2020. The increase was primarily driven by expenses associated with the expansion of capabilities to support the current and future pipeline of products, which includes higher payroll and related expenses on increases in staffing, laboratory expenses, third party technical services, and facility expenses, which were partially offset by lower field trial expenses. Higher facility costs related primarily to the costs associated with our corporate headquarters, into which we relocated in July 2020. Lower field trial expenses were driven by a scope reduction of our maize project.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the three months ended June 30, 2021 of $15.8 million increased $8.3 million as compared to the same period in 2020. The increase was primarily driven by higher professional fees, additional staff and related expenses and facility costs. The increase in professional fees, including accounting, legal and other consulting expenses, was predominantly driven by costs related to preparation to be a public company including nonrecurring costs of $2.0 million. The increase in staff and related expenses related to the increase in personnel necessary to support the scale of anticipated business operations and the requirements associated with being a public company. The increase in facility costs, which includes depreciation and amortization expense, was primarily attributable to costs associated with our corporate headquarters, into which we relocated in July 2020.

Total Other Expense (Income), Net

Total other expense (income), net for the three months ended June 30, 2021 of $2.8 million increased $0.3 million as compared to the same period in 2020. The increase was primarily driven by interest expense and remeasurements of our warrant liability associated with our notes payable. Also contributing to higher interest expense was interest on our financing leases, primarily driven by our headquarters lease which commenced in July 2020. The increases were partially offset by a decrease in the amortization of the debt discount and debt issuance costs associated with our notes payable as well as the other income generated in the period.

Income Tax (Benefit) Expense

No income tax benefit for net operating losses incurred in the U.S. has been recorded due to uncertainty in realizing a benefit from these items.

Revenues

Revenues for the six months ended June 30, 2021 were $71.5 million, an increase of $8.9 million as compared to the same period in 2020. As noted previously, in October 2020, we sold our barley operations, which contributed revenues of $8.5 million in the six months ended June 30, 2020. Excluding the contribution from the barley operations, revenues for the six months ended June 30, 2021 increased $17.4 million or 32%. The increase was primarily driven by higher sales volumes of our proprietary soybeans, soybean oil and soybean meal, of which commercialization efforts were initiated in the fourth quarter of 2020, higher average selling prices and sales volumes of yellow peas and higher sales volumes of fresh produce. Partially offsetting the increase was the impact of lower average selling prices of fresh produce. Lower average selling prices of fresh produce in 2021 were driven by higher regional and ex-US farm yields within the industry resulting in a higher supply versus demand.

Cost of Sales and Gross Profit

Cost of sales and gross profit for the six months ended June 30, 2021 of $71.0 million and $0.5 million, respectively, represented an increase in cost of sales of $17.2 million and a decrease in gross profit of $8.4 million as compared to the same period in 2020. For the six months ended June 30, 2021 and 2020, there were certain items expected to be non-recurring. In the second quarter of 2021, we incurred $2.8 million of higher freight costs necessary to transport soybean seed stock from South America, which is more fully discussed above. Also, as noted previously, we sold our barley operations in October 2020, which contributed $1.3 million in gross profit in the six months ended June 30, 2020.

Excluding the impact of items expected to be nonrecurring, as noted above, gross profit for the six months ended June 30, 2021 was $3.3 million, which represented a decline in profitability of $4.3 million. The decrease in gross profit was primarily driven by losses generated on the commercial launch of proprietary soybean oil and soybean meal as higher average selling prices were more than offset by start-up and other

117

operating costs associated with early-stage commercialization of these products, lower royalties from legacy seed distribution contracts, lower average selling prices on fresh produce and the higher acquisition costs of yellow peas.

Research and Development Expenses

Research and development expenses for the six months ended June 30, 2021 of $15.9 million increased $1.2 million as compared to the same period in 2020. The increase was primarily driven by higher payroll and related expenses on increases in staffing, technology costs and facilities, partially offset by lower third party technical services, field trial expenses and travel. Reductions in field trial expenses were primarily attributable to a scope reduction of our maize project. Higher facility costs related primarily to the costs associated with our corporate headquarters, into which we relocated in July 2020.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the six months ended June 30, 2021 of $29.5 million increased $14.0 million as compared to the same period in 2020. The increase was primarily driven by higher professional fees, increased staffing and related expenses and facility costs. The increase in professional fees, including accounting, legal and other consulting expenses, was predominantly driven by costs related to preparation to be a public company including nonrecurring costs of $3.8 million. The increase in staff and related expenses related to the increase in personnel necessary to support the scale of anticipated business operations and the requirements associated with being a public company. The increase in facility costs, which includes depreciation and amortization expense, was primarily attributable to costs associated with our corporate headquarters, into which we relocated in July 2020.

Total Other Expense (Income), Net

Total other expense (income), net for the six months ended June 30, 2021 of $4.9 million increased $1.4 million as compared to the same period in 2020. The increase was primarily driven by interest expense, amortization of the debt discount associated with our warrant liability and remeasurements of our warrant liability associated with our notes payable. Also contributing to higher interest expense was interest on our financing leases, primarily driven by our headquarters lease which commenced in July 2020.

Income Tax (Benefit) Expense

No income tax benefit for net operating losses incurred in the U.S. has been recorded due to uncertainty in realizing a benefit from these items.

Revenues

Revenues for the year ended December 31, 2020 were $114.3 million, an increase of $34.8 million as compared to 2019. The increase was primarily driven by twelve months of sales in our Fresh segment contrasted with seven months of sales for the same period of 2019 due to the acquisition of J&J Family of Farms completed on May 31, 2019. Partially offsetting this increase in revenues are declines in revenues in our Ingredients segment of approximately $3.0 million driven primarily by the sale of our barley operations, which was completed in October 2020, and on lower prices on sales of processed yellow pea driven by lower demand of our ingredients due to lower consumer demand of grain-free companion animal pet food.

Revenues for the year ended December 31, 2019 were $79.5 million, an increase of $75.3 million as compared to 2018. This increase was primarily driven by twelve months of sales of processed yellow pea in 2019 due to the acquisition of Dakota Ingredients on December 21, 2018, and seven months of sales in our Fresh segment in 2019 due to the acquisition of J&J Family of Farms, as further discussed above.

Cost of Sales and Gross Profit

Cost of sales and gross profit for the year ended December 31, 2020 of $102.4 million and $11.9 million, respectively, increased $31.5 million and $3.4 million, respectively, as compared to 2019. The increases were primarily driven by twelve months of sales in our Fresh segment contrasted with seven months of sales for the same period of 2019, as further discussed above. Partially offsetting these increases are declines in cost of sales and gross profit driven by the sale of our barley operations, and lower gross profit from sales of processed yellow pea, as further discussed above.

Cost of sales and gross profit for the year ended December 31, 2019 of $71.0 million and $8.6 million, respectively, increased $70.3 million and $5.0 million, respectively, as compared to 2018. The increases were primarily driven by twelve months of sales of processed yellow pea in 2019 due to the acquisition of Dakota Ingredients on December 21, 2018, and seven months of sales in our Fresh segment in 2019 due to the acquisition of J&J Family of Farms, as further discuss above.

Research and Development Expenses

Research and development expenses for the year ended December 31, 2020 of $29.5 million increased $4.6 million as compared to 2019. The increase was primarily due to increases in employee related expenses on higher staffing, including the use of external contractors, lower reimbursements on grants, higher facility/​depreciation expenses and higher field trial expenses, partially offset by lower laboratory supply expenses and travel, as impacted by supply chain disruptions driven by the COVID-19 global pandemic.

Research and development expenses for the year ended December 31, 2019 of $24.8 million increased $11.4 million as compared to 2018. The increase was primarily due to increases in employee related expenses on higher staffing, including external contractors, higher field trial expenses, higher laboratory supply expenses, higher facility/depreciation expenses and travel, as partially offset by an increase in reimbursement of expenses from grants.

Selling, General and Administrative Expenses

Selling, general and administrative expenses for the year ended December 31, 2020 of $37.4 million increased $10.0 million as compared to 2019. The increase was primarily driven by higher employee related

119

expenses, higher depreciation and facilities expense, higher business development expenses, higher litigation expenses and higher professional services as partially offset by lower acquisition fees and lower travel expenses. Also significantly contributing to the higher SG&A costs are twelve months of activity in our Fresh segment as compared to seven months of activity for the same period of 2019, as discussed above. Employee related expenses increased due to an increase in personnel in business development, legal, finance, human resources, communications and executive management necessary to support the anticipated growth of the Company. Depreciation and facilities expense increased due to us relocating to a corporate headquarters building in July 2020.

Selling, General and Administrative Expenses for the year ended December 31, 2019 of $27.5 million increased $18.3 million as compared to 2018. The increase was primarily driven by higher acquisition related expenses, higher employee related expenses, including higher contractors, higher technology/facilities expense, and higher accounting fees as partially offset by lower legal fees. Also significantly contributing to the higher SG&A costs are twelve months of activity due to the acquisition of Dakota Ingredients and seven months of activity in our Fresh segment as compared to no activity for the same period of 2018, due to the acquisition of J&J Family of Farms. Employee related expenses increased due to an increase in personnel in business development, legal, finance, human resources, communications and executive management necessary to support the anticipated growth of the Company.

Impairment of Goodwill

Impairment of goodwill charges for the year ended December 31, 2020 of $4.8 million were incurred due to non-cash charges of $3.0 million at our Ingredients segment and $1.8 million at our Fresh segment.

There were no impairment charges of goodwill for the year ended December 31, 2019 or 2018.

Total Other Expense (Income), Net

Total other expense (income), net for the year ended December 31, 2020 of $7.3 million increased $7.1 million as compared to the same period in 2019. The increase is primarily driven by interest expense, amortization of the commitment fee and debt discount associated with our warrant liability and remeasurements of our warrant liability associated with our notes payable. Also contributing to higher interest expense is interest on our financing leases, as primarily driven by our headquarters lease which commenced in July 2020. See Note 8 — Leases and Note 12 — Debt in our consolidated financial statements for additional information.

Total other expense (income), net for the year ended December 31, 2019 of $0.2 million increased $0.8 million. The increase is primarily due to higher interest expense on our term and revolving credit facility entered into by our wholly-owned subsidiary Dakota Ingredients in April 2019.

Income Tax (Benefit) Expense

No income tax benefit for net operating losses incurred in the U.S. has been recorded due to uncertainty in realizing a benefit from these items. The provision for income taxes for the years ended December 31, 2020, 2019 and 2018 relate primarily to activity in foreign jurisdictions.

Results of Operations by Segment

The Company operates in two reportable segments: Ingredients and Fresh. The Ingredients segment delivers healthy food ingredients derived from soybean seeds, including meal and oil, and processed yellow peas. The Fresh segment is a grower, packer and distributor of year-round fresh produce located in the southeastern United States. Financial results associated with licensing arrangements that are not related to the Ingredients and Fresh segments and costs associated with centralized operations, including unallocated research and development expenses, are reported as Unallocated and Other.

Ingredients revenues for the three and six months ended June 30, 2021 were $22.7 million and $36.9 million, respectively, which represents an increase of $4.9 million and $7.4 million, respectively, as compared to the same periods in 2020. The increase for both periods was predominantly driven by sales attributable to the commercial launch of our proprietary soybean oil and soybean meal, higher sales volumes and average selling prices of yellow peas, as partially offset by a lack of sales of barley in 2021. Lower sales of barley for the three and six months ended June 30, 2021 of $4.0 million and $8.5 million, respectively, as compared to the same period in 2020, were due to the sale of this business operation in October 2020.

Fresh revenues for the three and six months ended June 30, 2021 were $16.9 million and $34.5 million, respectively, which represents an increase of $4.7 million and $2.5 million, respectively, as compared to the same periods in 2020. The increase for both periods was primarily driven by higher sales volumes as partially offset by lower average selling prices. Lower average selling prices in our Fresh segment in 2021 were driven by higher regional and ex-US farm yields within the industry resulting in a higher supply versus demand.

Segment Profit

Adjusted EBITDA is a non-GAAP financial measure of performance. Among other financial metrics, our management reviews segment profit based upon Adjusted EBITDA. We calculate Adjusted EBITDA as earnings from continuing operations before net interest expense, income tax provision and depreciation and amortization, further adjusted to exclude stock-based compensation, and the impact of significant non-recurring items.

We believe that Adjusted EBITDA is useful in comparing our financial performance with the performance of other companies for the following reasons:

•

Adjusted EBITDA is widely used by investors and securities analysts to measure a company’s operating performance without regard to items such as stock-based compensation expense, depreciation and interest expense, that can vary substantially from company to company depending upon their financing and capital structures, and the method by which assets were acquired; and

•

Adjusted EBITDA provides consistency and comparability with our past financial performance, and facilitates comparisons with other companies, many of which use similar non-GAAP financial measures to supplement their GAAP results.

Our use of Adjusted EBITDA has limitations as an analytical tool, and you should not consider this measure in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitations are as follows:

•

Although depreciation expense is a non-cash charge, the assets being depreciated may have to be replaced in the future, and Adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditure requirements;

121

•

Adjusted EBITDA excludes stock-based compensation expense, which has been, and will continue to be for the foreseeable future, a significant recurring non-cash expense for our business and an important part of our compensation strategy;

•

Adjusted EBITDA excludes other material non-recurring items;

•

Adjusted EBITDA does not reflect: (1) recurring changes in, or cash requirements for, our working capital needs; (2) interest expense, or the cash requirements necessary to service interest or principal payments on our debt, which reduces cash available to us; or (3) tax payments that may represent a reduction in cash available to us; and

•

the expenses and other items that we exclude in our calculation of Adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude from Adjusted EBITDA when they report their operating results.

Because of these limitations, Adjusted EBITDA should be considered along with other operating and financial performance measures presented in accordance with GAAP. Adjusted EBITDA for each of the three and six month periods ended June 30, 2021 and 2020, is presented below. A reconciliation of our consolidated loss from continuing operations to Adjusted EBITDA is also presented below.

Ingredients Adjusted EBITDA was a loss of $6.4 million and $13.2 million for the three and six months ended June 30, 2021, respectively, which represents a decrease in segment profit of $3.9 million and $8.6 million, respectively, as compared to the same periods in 2020. The decrease was primarily driven by losses generated on the commercial launch of our proprietary soybean oil and soybean meal as higher average selling prices were more than offset by start-up and other operating costs associated with early-stage commercialization of these products, a lack of sales and gross profit on barley as driven by our sale of this business in October 2020, and higher research and development costs associated with products anticipated to be commercialized within this segment, if successful. Also, in the second quarter of 2021, we incurred $2.8 million of higher freight costs necessary to transport high protein soybean seed stock from South America to our US-based operations. These costs, which we do not believe to be recurring, were the result of us utilizing the South America growing season to prepare us for our US-based 2021 soybean harvest.

Fresh Adjusted EBITDA was a profit of $0.2 million for the three  months ended June 30, 2021 and a loss of $0.2 million for the six  months ended June 30, 2021, which represents a decrease of $0.7 million and $2.6 million, respectively, as compared to the same periods in 2020. This decrease was driven by lower average selling prices and higher operating expenses, including higher freight costs, as partially offset by higher sales volumes.

Comparison of the years ended December 31, 2020, 2019 and 2018

Segment Revenues

Segment revenues for the years ended December 31, 2020, 2019 and 2018, are presented below:

​	Year Ended December 31,

Total Revenues	​	$	114,348	​	$	79,523	​	$	4,269

Ingredients revenues for the year ended December 31, 2020 were $58.6 million, an increase of $9.4 million as compared to 2019. The increase was primarily driven by higher volumes of processed yellow pea and soybean seeds, higher licensing fees of intellectual property, partially offset by lower processed yellow pea prices and reduced barley sales driven by the sale of this business in October 2020. Ingredients revenues for the year ended December 31, 2019 were $49.2 million, an increase of $48.5 million. This increase was driven by twelve months of sales of processed yellow pea in 2019 as contrasted with 10 days in 2018 as the acquisition of Dakota Ingredients was completed on December 21, 2018. Also contributing to the increase in revenues in 2019 was the benefit of eleven months of sales of soybean seeds and soybean licensing fees related to an acquisition completed on February 7, 2019.

Fresh revenues for the year ended December 31, 2020 were $55.3 million, an increase of $26.7 million. The increase was primarily driven by twelve months of sales recognized in 2020 as contrasted with seven months of sales in 2019 as the acquisition of J&J Family of Farms was completed on May 31, 2019. Fresh revenues for the year ended December 31, 2019 were $28.6 million as compared to zero for the same period in 2018. This increase was due to the start-up of these business operations in 2019 upon the acquisition of J&J Family of Farms on May 31, 2019.

Ingredients Adjusted EBITDA was a loss of $8.0 million for the year ended December 31, 2020, a decrease of $10.2 million. This decrease was driven by higher volumes of processed yellow pea sales offset by higher cost of yellow peas, higher operating costs and a higher research and development costs associated with products anticipated to be commercialized within this segment Ingredients Adjusted EBITDA was $2.2 million for the year ended December 31, 2019, an increase of $2.2 million. This increase was driven by twelve months of operations associated with sales of processed yellow pea in 2019 as compared to 10 days in 2018 as the acquisition of Dakota Ingredients was completed on December 21, 2018.

Fresh Adjusted EBITDA was $0.2 million for the year ended December 31, 2020, an increase in profitability of $1.5 million. This increase was driven by twelve months of sales recognized in 2020 as contrasted with seven months of sales in 2019 as the acquisition of J&J Family of Farms was completed on May 31, 2019. Fresh Adjusted EBITDA for the year ended December 31, 2019 was a loss of $1.3 million as compared to zero for the same period in 2018. This increase was due to the commencement of the business operations of the Fresh segment in 2019 upon the acquisition of J&J Family of Farms on May 31, 2019.

Liquidity and Capital Resources

Liquidity describes the ability of us to generate sufficient cash flows to meet the cash requirements of our business operations, including working capital needs, debt service, acquisitions, contractual obligations and other commitments. We assess liquidity in terms of our ability to access cash flows from operations, marketable securities and available credit facilities and their sufficiency to fund our operating, investing and financing activities. To meet our payment service obligations, we must have sufficient highly liquid assets and be able to move funds on a timely basis.

To date, the Company has been funded primarily by equity and debt financings, including the issuance of redeemable convertible preferred stock and term debt, as well as the use of a revolving line of credit, which is subject to renewal in September 2021. Our principal sources of liquidity at June 30, 2021 were our cash and marketable securities, which total $42.6 million and access to a revolving credit facility of up to $6.0 million, as capped by a defined borrowing base that could result in availability that is less than this amount. As of June 30, 2021, our commitments include term debt and notes payable outstanding of $28.9 million, an outstanding revolver balance of $3.0 million, lease liabilities of $35.6 million, capital expenditures associated with expansion of farming and R&D operations, to be completed in 2021, within our Fresh segment, capital expenditures associated with the construction of a crop accelerator facility to be used in the development of our products, also to be completed in 2021, and operating costs supporting the sale of products, R&D, and selling, general and administrative expenses. For the six months ended June 30, 2021, we incurred a net loss of $49.8 million and had negative cash flows from operating activities of $47.3 million and violated certain financial covenants under our term debt agreement, which were subsequently waived. In the absence of the Company obtaining additional funding of either equity or debt, there is substantial doubt about our ability to continue as a going concern within one year after the date that the financial statements are available to be issued.

Upon consummation of the merger and the closing of the PIPE Investment, and as a partial use of proceeds, we plan to repay our existing term debt, any outstanding amount on our revolving line of credit, and our notes payable. In conjunction with this early extinguishment, we expect to incur prepayment penalties estimated at $3.4 million. After the repayment of these debt agreements, it is expected that our cash and cash equivalents will increase an estimated $144 million, assuming maximum stockholder redemptions of all 40.3 million STPC public shares, or approximately $546 million, assuming no redemptions, and, in each case, including $225 million in gross proceeds from the PIPE Investment by the PIPE Investors. Total direct and incremental transaction costs of STPC and Benson Hill are estimated at approximately $50.0 million, including the payment of deferred underwriting and other transaction fees of $14.1 million associated with STPC’s IPO. Underwriting and other transaction fees associated with the merger are estimated at $35.9 million, of which $28.9 million will be treated as a reduction from New Benson Hill’s additional paid-in capital and $7.0 million will be expensed. See the section entitled “Unaudited Pro Forma Combined Financial Information.”

Our business prospects are subject to risks, expenses, and uncertainties frequently encountered by companies in the early stages of commercial operations. Certain of our existing debt financings require our wholly-owned subsidiary, Dakota Ingredients, to comply with financial covenants that will likely require

124

financial support from Benson Hill to remain in compliance with the financial covenants during 2021 and 2022. See Note 11 — Debt to the unaudited condensed consolidated financial statements as of June 30, 2021 for further discussion. Further, these same debt financings currently require Benson Hill to maintain a minimum cash balance. If we are unable to complete the merger and repay these debt financings or if we breach these covenants, the holder of the debt may declare all amounts immediately due and payable. If the covenants are breached, we plan to attempt to secure a waiver of the covenants or an amendment that modifies the covenants but there are no assurances that we will be able to comply with our future covenants without such a waiver or that we will be successful in obtaining a waiver or an amendment during 2021.

The attainment of profitable operations is also dependent upon future events, including obtaining adequate financing to complete and commercialize our research and development activities, obtaining adequate grower relationships, building our customer base, successfully executing our business and marketing strategy and hiring appropriate personnel. Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, maintain existing debt arrangements, consummate the merger or secure additional funding may require us to modify, delay, or abandon some of our planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on our business, operating results, financial condition, and ability to achieve our intended business objectives.

The Company could potentially use its available financial resources sooner than it currently expects and may need to incur additional indebtedness to meet future financing needs. The merger agreement currently restricts our ability to incur additional indebtedness without the written consent of STPC (which may not be unreasonably withheld, conditioned or delayed) until the closing of the merger. If consented to by STPC, adequate additional funding may not be available to the Company on acceptable terms or at all. In addition, although the Company anticipates being able to obtain additional financing through non-dilutive means, it may be unable to do so. The Company’s failure to raise capital as and when needed could have significant negative consequences for our business, financial condition and results of consolidated operations. The Company’s future capital requirements and the adequacy of available funds will depend on many factors, including those set forth in the section titled “Risk Factors — Risks Related to Benson Hill's Business and Industry.”

Net Cash Used in Operating Activities

Net cash used in operating activities was $47.3 million for the six months ended June 30, 2021, an increase of $24.7 million as compared to the same period in 2020. This increased use of cash was driven by a higher net loss of $24.9 million, as partially offset by higher non-cash charges of $4.0 million, and a higher use of working capital of $3.8 million. A higher use of working capital was primarily driven by higher inventory and accounts receivable balances, driven predominantly by our Ingredients segment, and lower

125

accounts payable and accrued liabilities, as partially offset by lower prepaid expenses and other current assets. The increase in non-cash charges were primarily comprised of higher depreciation and amortization, higher share-based compensation expense, driven by higher tangible and intangible assets, and a mark-to-market expense of our preferred stock warrant.

Net cash used in operating activities was $52.7 million for the year ended December 31, 2020, an increase of $8.3 million as compared to 2019. This increased use of cash was driven by an increase in our net loss of $23.2 million, as partially offset by higher non-cash charges of $12.2 million and a lower use of working capital of $2.5 million. The increase in non-cash charges were primarily comprised of higher depreciation and amortization, as driven by higher tangible and intangible assets, impairment of goodwill, amortization of financing fees, and a mark-to-market of our preferred stock warrant. A lower utilization of working capital was primarily driven by higher accounts payable and accrued liabilities.

Net cash used in operating activities was $44.4 million for the year ended December 31, 2019, an increase of $31.0 million as compared to 2018. This increased use of cash was driven by an increase in our net loss of $25.8 million and in increase in use of working capital of $9.0 million as partially offset by higher non-cash charges of $3.8 million. The increase in use of working capital was primarily due to lower deferred revenue on licensing agreements and higher accounts receivable and inventories associated with our Ingredients segment. The increase in non-cash charges were primarily comprised of higher depreciation and amortization on tangible and intangible assets.

Net Cash Provided by (Used in) Investing Activities

Net cash provided by investing activities was $49.3 million for the six months ended June 30, 2021, an increase of $46.3 million as compared to the same period in 2020. This increase was driven by the corresponding net decrease in marketable securities (maturities and sales of marketable securities less purchases of marketable securities) of $70.5 million in 2021, as compared to $8.1 million in the same period of 2020, and higher capital expenditures of $16.0 million. Higher capital expenditures in 2021 were primarily due to the purchase of land and construction costs incurred toward the expansion of farm operations in Vero Beach, Florida in our Fresh segment. The total projected cost of this project, to be completed in the fourth quarter of 2021, is expected to be in the range of $26.0 million to $27.0 million.

Net cash used in investing activities was $100.7 million for the year ended December 31, 2020, an increase of $96.1 million as compared to the year ended December 31, 2019. This increase was driven by the net increase in marketable securities (purchases of marketable securities less maturities and sales of marketable securities) of $92.5 million in 2020, as compared to net liquidation in marketable securities (maturities and sales of marketable securities less purchase of marketable securities) of $29.1 million in 2019, and higher capital expenditures of $3.0 million, as partially offset by proceeds from the divestiture of certain assets of $1.7 million as compared to payments in connection with business acquisitions in 2019 of $26.8 million. Higher capital expenditures in 2020 were primarily due to equipment and other build out costs associated with our corporate headquarters, which we took possession of in July 2020. The lower use of cash on business acquisitions are due to the completion of the purchase of two businesses in 2019 as compared to the divestiture of our Barley business in October 2020.

Net cash used in investing activities was $4.5 million for the year ended December 31, 2019, a decrease of $44.1 million as compared to the year ended December 31, 2018. This decrease was driven by the net liquidation of marketable securities of $29.1 million in 2019, as compared to the net increase of marketable securities of $24.9 million in 2018, as partially offset by higher capital expenditures of $5.8 million and a higher use of cash on business acquisitions of $4.1 million. The higher capital expenditures in 2019 were primarily due to the expansion of capacity of yellow pea processing in our Ingredients segment.

Net Cash Provided by Financing Activities

Net cash provided by financing activities was $1.2 million for the six months ended June 30, 2021, a decrease of $21.7 million as compared to the same period in 2020. In the six months ended June 30, 2021, no term debt was issued, as compared to new term debt with net proceeds of $24.1 million for the same period in 2020. Net borrowings under our revolving line of credit increased $3.2 million, as compared to the same

126

period in 2020. For the six months ended June 30, 2021, we made payments of $0.3 million in capitalized offering costs associated with our anticipated merger with STPC.

Net cash provided by financing activities was $160.7 million for the year ended December 31, 2020, an increase of $112.2 million as compared to the year ended December 31, 2019. The increase was primarily driven by higher proceeds from the issuance of $121.9 million Benson Hill Preferred Stock, and higher borrowings of debt of $9.2 million as partially offset by higher payments on our term and revolving debt, net of revolver borrowings, of $11.1 million and the retirement of preferred stock of $7.8 million.

Net cash provided by financing activities was $48.6 million for the year ended December 31, 2019, a decrease of $15.1 million as compared to the year ended December 31, 2018. The decrease was driven by lower proceeds from the issuance of $32.3 million Benson Hill Preferred Stock as partially offset by higher borrowings of debt of $15.3 million and higher payments on our term and revolving debt, net of revolver borrowings, of $1.9 million.

Off-Balance Sheet Arrangements

The Company has not entered into off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Estimates

Our discussion and analysis of financial condition and results of operations are based upon our consolidated financial statements included elsewhere in this proxy statement/prospectus. The preparation of our consolidated financial statements in accordance with GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue and expenses. We base our estimates on past experience and other assumptions that we believe are reasonable under the circumstances, and we evaluate these estimates on an ongoing basis. Actual results may differ from those estimates.

Our critical accounting policies are those that materially affect our consolidated financial statements and involve difficult, subjective or complex judgments by management. A thorough understanding of these critical accounting policies is essential when reviewing our consolidated financial statements. We believe that the critical accounting policies listed below involve the most difficult management decisions because they require the use of significant estimates and assumptions as described above.

See Note 2 — Summary of Significant Accounting Policies to our audited financial statements included elsewhere in this proxy statement/prospectus for more information.

Revenue Recognition

We generate revenue from product sales, licensing fees associated with our proprietary technology platform and/or our intellectual property, and commissions earned on product sales.

127

Product Sales

We recognize revenue on product sales, consisting primarily of harvested produce, processed yellow pea, barley, soybeans, and soybean meal and oil, at the point in time when obligations under the terms of a contract with the customer are satisfied. This generally occurs at the time of transfer of control of the product. In reaching this conclusion, the Company considers several control indicators of the timing of the transfer of control, including significant risks and rewards of ownership, physical possession, and the Company’s right to receive payment. Shipping and handling costs related to contracts with customers for product sales are accounted for as a fulfillment activity and not as a separate performance obligation to customers.

In addition to selling our own farmed produce, we enter into consignment arrangements with produce growers and packers located outside of the U.S. and growers of certain perishable products in the U.S. Within these arrangements, the Company is acting as an agent and earns a stated commission and as such revenue is reported on a net basis representing the commissions earned in the Company’s consolidated statement of operations. For certain of these transactions, the Company is responsible for shipping and handling activities. When that is the case, revenue is recognized for those services as performed.

Sales, use, value-added, and other excise taxes are excluded from the measurement of the transaction price. We generally do not allow a right of return.

Software as a Service (“SAAS”)

We enter into contractual arrangements, which provide access to our proprietary platform CropOS®. CropOS® is designed to facilitate the accessibility and actionability of certain data, machine learning and artificial intelligence techniques to enable predictive breeding.

Customers have access to this data and functionality, but not access to any of Benson Hill’s propriety patents or other intellectual property. Customers typically pay for this service with an annual subscription and the Company recognizes revenue under SAAS contracts on a straight-line basis over the term of the contract.

Research Licenses

We enter into contractual arrangements, which provide customers the right to use our proprietary intellectual property and/or patents under a research license for a specific period of time. Customers receive all intellectual property and “know how” at the start of the contract and may perform all desired research to incorporate Benson Hill’s intellectual property into potential new strains and breeds of germplasm. Contracts provide for up-front payments as well as milestone payments and royalties based on commercial sales involving the licensed technology at some point in the future when, and if, commercialization occurs. These contracts are considered functional licenses and revenue is recorded at the inception of the contract for the amount the customer is contractually obligated to pay and for which collectability is probable.

For the three and six months ended June 30, 2021 and 2020, and for the years ended December 31, 2020, 2019 and 2018, commercialization had not occurred nor was probable and therefore no revenue was recognized for these periods.

Stock-Based Compensation

The Company recognizes in its Consolidated Statements of Operations and Comprehensive Loss the grant-date fair value of stock options issued to employees and directors. The Company’s options are subject only to service-based vesting conditions. Stock-based compensation expense is recognized on a straight-line basis over the associated service period of the award, which is generally the vesting term. The Company recognizes forfeitures of awards as they occur.

The Company estimates the fair value of its stock option awards using the Black-Scholes option pricing model, which requires the input of subjective assumptions, including the fair value of the Company’s common stock, expected term, expected volatility, risk-free interest rate and expected dividends.

Fair Value of Common Stock — Historically, as there has been no public market for the Company’s common stock, the fair value of its common stock was determined by the board of directors based in part on valuations of the common stock prepared by a third-party valuation firm.

128

Expected Term — The expected term of the options represents the average period the stock options are expected to remain outstanding. As the Company does not have sufficient historical information to develop reasonable expectations about future exercise patterns and post-vesting employment termination behavior, the expected term of options granted is derived from the average midpoint between the weighted average vesting and the contractual term, also known as the simplified method.

Expected Volatility — Since the Company is not a public company and does not have any trading history for its common stock, the expected volatility is based on the historical volatilities of the common stock of comparable publicly traded companies.

Risk-Free Interest Rate — The risk-free interest rate is based on the yield of zero-coupon U.S. Treasury notes as of the grant date with maturities commensurate with the expected term of the awards.

Expected Dividends — The expected dividends assumption is based on the expectation of not paying dividends in the foreseeable future; therefore, the Company used an expected dividend yield of zero.

The grant date fair value for the Company’s stock options granted in the six months ended June 30, 2021 and the year ended December 31, 2020, respectively, were based on the following assumptions used within the Black-Scholes option pricing model:

​	2021		2020
Expected term	6.1 years		6.2 years
Risk-free interest rate	​	0.7%	​	1.0%
Expected volatility	​	63%	​	58%
Expected dividend yield	​	0%	​	0%

Assumptions used in applying the Black-Scholes option-pricing model to determine the estimated fair value of stock options granted involve inherent uncertainties and the application of judgment. As a result, if factors or expected outcomes change and significantly different assumptions or estimates are used, the Company’s equity-based compensation could be materially different.

Impairment of Goodwill and Intangible Assets

Goodwill, arising from a business combination as the excess of purchase price and related costs over the fair value of identifiable assets acquired and liabilities assumed is not amortized and is subject to an annual impairment test as of December 1, unless events indicate an interim test is required. In performing this impairment test, management will first qualitatively assess indicators of a reporting unit’s fair value. If after completing the qualitative assessment, management believes it is likely that a reporting unit is impaired, a discounted cash flow analysis is prepared to estimate the fair value of the reporting unit.

Critical estimates in the determination of the fair value of each reporting unit include, but are not limited to, future expected cash flows based on estimates of future sales volumes, sales prices, production costs, and discount rates. These estimates generally constitute unobservable Level 3 inputs under the fair value hierarchy. An adjustment to goodwill will be recorded for any goodwill that is determined to be impaired. Impairment of goodwill is measured as the excess of the carrying amount of goodwill over the fair value of the reporting unit.

Intangible assets consist primarily of customer relationships, trade names, employment agreements, technology licenses, and in-process research and development (IPRD). Intangible assets are valued based on the income approach which utilizes discounted cash flows. These estimates generally constitute Level 3 inputs under the fair value hierarchy.

Acquired IPRD, consisting of seed germplasm, is considered an indefinite-lived intangible asset until the abandonment or completion of the associated research and development efforts. If abandoned, or our projections regarding the costs to complete the research and future revenues and cash flows require adverse revisions, the assets would be impaired. If the activities are completed, a determination is made regarding the useful lives of such assets and methods of amortization.

129

Similar to goodwill, indefinite lived intangible assets are subject to an annual impairment test as of December 1, unless events indicate an interim test is required.

In conjunction with business acquisitions, we obtain trade names, enter into employment agreements, and gain access to the distribution channels and customer relationships of the acquired companies. Trade names are amortized over their estimated useful life, which is generally ten years. Employment agreements are being amortized over the contractual period, which is two years. Customer relationships are expected to provide economic benefits to the Company over the estimated life of the relationship, which is generally 15 years, and are amortized on a straight-line basis. The amortization period of customer relationships represents management’s best estimate of the expected usage or consumption of the economic benefits of the acquired assets, which is based on our historical experience of customer attrition rates.

Definite lived intangible assets are reviewed for impairment, at the asset group level, whenever, in management’s judgement, impairment indicators are present. At a minimum, we assess all definite lived intangible assets annually for indicators of impairment. When indicators of impairment are presents, such an assessment involves estimating undiscounted cash flows over the remaining useful life of the intangible. If the review indicates that undiscounted cash flows are less than the carrying value of the intangible asset, the asset group is written down to fair value, and any impairment is assigned to the asset in the asset group in accordance with the applicable guidance, and a corresponding impairment is recognized in the consolidated statement of operations and comprehensive loss.

Derivatives

The Company has master netting agreements with its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Further, all of the Company’s derivative contracts are centrally cleared and therefore are cash-settled on a daily basis which results in the derivative contracts having a fair value that approximates zero on a daily basis.

The accounting for changes in the fair value (i.e., gains or losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and on the type of hedging relationship. All of the Company’s derivatives have not been designated as hedging instruments, and as such, changes in fair value of these derivatives are recognized in earnings immediately.

The Company’s soybean positions are designed to hedge risk related to inventory purchases therefore the gains and losses on soybean instruments are recorded in cost of sales in the consolidated statements of operations. The Company’s oil positions are designed to hedge risk related to sales transactions therefore the gains and losses on oil instruments are recorded in revenues in the consolidated statements of operations.

The Company classifies the cash effects of its derivatives within the “Cash Flows From Operating Activities” section of the condensed consolidated statements of cash flows.

Convertible Preferred Stock Warrant Liability

We evaluate whether our warrants for shares of convertible redeemable preferred stock are freestanding financial instruments that obligate us to redeem the underlying preferred stock at some point in the future and determined that each of our outstanding warrants for convertible preferred stock are liability classified. The warrants are subject to re-measurement at each balance sheet date, and any change in fair value is recognized in the change in fair value of warrants and embedded derivatives in the consolidated statements of operations. We will continue to remeasure the warrants until the earlier of the exercise or expiration, the completion of a deemed liquidation event, the conversion of convertible preferred stock into common stock, or until holders of the convertible preferred stock can no longer trigger a deemed liquidation event. On expiration, the convertible preferred stock warrants will automatically net exercise, unless the warrant holder provides written notice that it does not wish to exercise its warrants. Upon exercise, the related convertible preferred stock warrant liability will be reclassified to convertible preferred stock.

We estimate the fair value of these liabilities based on a Monte Carlo simulation that values the warrants using a probability weighted discounted cash flow model. Generally, increases or decrease in the fair value of the underlying convertible preferred stock would result in a directionally similar impact in the fair value measurement of the associated warrant liability.

130

Income Tax Valuation Allowances

The determination of the income tax valuation allowances requires us to use judgements and assumptions that may have a material impact on our consolidated financial statements, especially at the early stage of commercialization. We provide deferred taxes for deductible and taxable temporary differences. Deferred tax assets are reduced by a valuation allowance when we believe it is more likely than not that some portion or all the deferred tax assets will not be realized. Because we generate losses currently, a full valuation allowance is recorded against our net deferred tax assets, as we believe it is more likely than not that some portion or all the deferred tax assets will not be realized. If we were to generate cumulative profits, the valuation allowance may change.

Recent Accounting Guidance

From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on the Company’s financial position or results of operations under adoption. See Note 2 — Summary of Significant Accounting Policies to the accompanying unaudited condensed consolidated financial statements of the Company included elsewhere in this proxy statement/prospectus for more information about recent accounting pronouncements, the timing of their adoption and the Company’s assessment, to the extent the Company has made one, of their potential impact on the Company’s financial condition and results of operations.

Quantitative and Qualitative Disclosures about Market Risk

Market risk represents the risk of loss that may impact our financial position because of adverse changes in financial market prices and rates. Our market risk exposure is primarily a result of exposure resulting from potential changes in inflation, exchange rates or interest rates. We do not hold financial instruments for trading purposes.

Foreign Currency Exchange Risk

Our expenses are generally denominated in U.S. dollars. However, we have foreign currency risks related to operating expenses denominated in Canadian dollars and Brazilian reals and intercompany loans denominated in Brazilian reals. We have entered into a limited number of operation support contracts with vendors with payments denominated in foreign currencies. We are subject to foreign currency transaction gains or losses on our contracts denominated in foreign currencies. To date, foreign currency transaction gains and losses have not been material to our financial statements.

Although unfavorable changes in foreign exchange rates versus the U.S. dollar could adversely affect our consolidated statement of operations, we do not believe that an immediate 10% increase or decrease in the relative value of the U.S. dollar to other currencies would have a material effect on operating results or financial condition. We have not engaged in the hedging of foreign currency transactions to date, although we may choose to do so in the future.

Interest Rate Risk

Interest rate risk is the risk that the value or yield of fixed-income investments may decline if interest rates change. Fluctuations in interest rates may impact the level of interest expense recorded on outstanding borrowings. In addition, our notes payable, financing obligations bear interest at a fixed rate and are not publicly traded. Therefore, fair value of our notes payable, financing obligations and interest expense is not materially affected by changes in the market interest rates. We do not enter into derivative financial instruments, including interest rate swaps, for hedging or speculative purposes.

131

Credit Risk

Credit risk with respect to accounts receivable is generally not significant due to a limited carrying balance of receivables. We routinely assess the creditworthiness of our customers. We generally have not experienced any material losses related to receivables from individual customers, or groups of customers for the six months ended June 30, 2021 and 2020, and for the years ended December 31, 2020, 2019 and 2018. We do not require collateral. Due to these factors, no additional credit risk beyond amounts provided for collection losses is believed by management to be probable in our accounts receivable.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT OF NEW BENSON HILL

The following table sets forth information regarding (i) unless otherwise indicated in the footnotes below, the actual beneficial ownership of STPC common stock as of June 30, 2021 (the “Ownership Date”), which is prior to the consummation of the merger and the other transactions contemplated by the merger agreement (“pre-business combination”) and (ii) expected beneficial ownership of New Benson Hill Common Stock immediately following the consummation of the merger and the other transactions contemplated by the merger agreement (“post-business combination”), assuming that (x) no shares of Class A Common Stock are redeemed and (y) 40,250,000 shares of Class A Common Stock are redeemed for an aggregate payment of approximately $402.6 million from the Trust Account, which is the maximum amount of redemptions that would satisfy STPC having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) of the Exchange Act) remaining after the closing, by:

•

each person who is, or is expected to be, the beneficial owner of more than 5% of issued and outstanding shares of STPC common stock or of New Benson Hill Common Stock;

•

each of our current executive officers and directors;

•

each person who will (or is expected to) become an executive officer or director of New Benson Hill following the consummation of the merger; and

•

all executive officers and directors of STPC as a group pre-business combination and all executive officers and directors of New Benson Hill post-business combination.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within sixty (60) days.

The beneficial ownership of shares of STPC Common Stock pre-business combination is based on 50,312,500 outstanding shares of STPC common stock (including 40,250,000 shares of Class A Common Stock and 10,062,500 shares of Class B Common Stock) issued and outstanding as of the Ownership Date. The ownership percentages listed below do not include any such shares of Class A Common Stock that may be purchased after the Ownership Date.

See “Basis of Presentation and Glossary” for information with respect to assumptions underlying New Benson Hill share calculations and ownership percentages.

The expected beneficial ownership of shares of New Benson Hill Common Stock post-business combination in the “No Redemptions” column in the table below has been determined based upon the following additional assumptions: (i) no holders of Class A Common Stock exercise their redemption rights and (ii) that there are 209,653,707 shares of New Benson Hill Common Stock outstanding (including shares issuable upon the exercise of outstanding Benson Hill Options and Benson Hill Warrants within sixty (60) days from the Ownership Date).

The expected beneficial ownership of shares of New Benson Hill Common Stock post-business combination in the “Maximum Possible Redemption” column in the table below has been determined based upon the following additional assumptions: (i) 40,250,000 shares of Class A Common Stock are redeemed for an aggregate payment of approximately $402.6 million from the Trust Account, which is the maximum amount of redemptions that would satisfy STPC having at least $5,000,001 of net tangible assets (as determined in accordance with Rule 3a51-1(g)(1) under the Exchange Act) remaining after the closing; and (ii) that there are 169,403,707 shares of New Benson Hill Common Stock outstanding (including shares issuable upon the exercise of outstanding Benson Hill Options and Benson Hill Warrants within sixty (60) days from the Ownership Date).

Composition of the New Benson Hill Board of Directors After the Merger

We intend to have nine (9) directors upon completion of the merger. Our board of directors will have only one class of directors, with each director being elected in each year at our annual meeting of stockholders. See “Description of New Benson Hill Capital Stock — Anti-Takeover Effects of New Benson Hill’s Proposed Charter and Bylaws and Certain Provisions of Delaware Law.”

Director Independence

The NYSE listing standards require that a majority of our board of directors be independent. An “independent director” is defined generally as a person who has no material relationship with the listed company (either directly or as a partner, stockholder or officer of an organization that has a relationship with the company). Our board of directors has determined that each of      ,        and         are “independent directors” as defined in the NYSE listing standards and applicable SEC rules. Pursuant to NYSE’s phase-in rules for newly listed companies, we have one (1) year from the date on which we are first listed on NYSE to for a majority of our board of directors be independent. Our independent directors will have regularly scheduled meetings at which only independent directors are present.

Officer and Director Compensation

Overview

Following the closing of the merger, we expect New Benson Hill’s executive compensation program to be consistent with Benson Hill’s existing compensation policies and philosophies, which are designed to:

142

•

attract, retain and motivate senior management leaders who are capable of advancing our mission and strategy and ultimately, creating and maintaining our long-term equity value. Such leaders must engage in a collaborative approach and possess the ability to execute our business strategy in an industry characterized by competitiveness and growth;

•

reward senior management in a manner aligned with our financial performance; and

•

align senior management’s interests with our equity owners’ long-term interests through equity participation and ownership.

Following the closing of the merger, decisions with respect to the compensation of our named executive officers will be made by the compensation committee of our board of directors. The following discussion is based on the present expectations as to the compensation of our named executive officers and directors following the merger. The actual compensation of our named executive officers will depend on the judgment of the members of the compensation committee and may differ from that set forth in the following discussion.

We anticipate that compensation for our executive officers will have the following components: base salary, cash bonus opportunities, long-term incentive compensation, broad based employee benefits, supplemental executive perquisites and severance benefits. Base salaries, broad-based employee benefits, supplemental executive perquisites and severance benefits will be designed to attract and retain senior management talent. We also expect to use annual cash bonuses and long-term equity awards to promote performance-based pay that aligns the interests of our executive officers with the long-term interests of our equity-owners and to enhance executive retention. In addition, we expect to finalize employment agreements with New Benson Hill's Chief Executive Officer, Chief Financial Officer and Chief Technology Officer prior to, and effective upon, the closing of the merger.

Base Salary

We expect that our executive officers’ base salaries in effect prior to the merger will continue as described under “Executive and Director Compensation of Benson Hill,” subject to potential increases made in connection with the negotiation of any employment agreements or Benson Hill’s annual review of its executive officers’ base salaries. Following the merger, our executive officers’ base salaries will be reviewed annually by the compensation committee.

Annual Bonuses

We expect that New Benson Hill will use annual cash incentive bonuses for the executive officers to motivate their achievement of short-term performance goals and tie a portion of their cash compensation to performance. We expect that, near the beginning of each year, the compensation committee will select the performance targets, target amounts, target award opportunities and other terms and conditions of annual cash bonuses for the executive officers, subject to the terms of their employment agreements. Following the end of each year, the compensation committee will determine the extent to which the performance targets were achieved and the amount of the award that is payable to the executive officers.

Stock-Based Awards

We expect New Benson Hill to use stock-based awards in future years to promote our interest by providing these executives with the opportunity to acquire equity interests as an incentive for their remaining in our service and aligning the executives’ interests with those of New Benson Hill’s equityholders. Any stock-based awards will be awarded in future years under the Incentive Plan. For a description of the Incentive Plan, please see “Proposal No. 7 — The Incentive Plan Proposal.”

Other Compensation

We expect New Benson Hill to continue to maintain various employee benefit plans currently maintained by Benson Hill, including medical, dental, vision, life insurance and 401(k) plans, paid time off and holidays and employee assistance program benefits in which the executive officers will participate. We also expect New Benson Hill to continue to provide its executive officers with specified perquisites and personal benefits

143

currently provided by Benson Hill that are not generally available to all employees. For additional details, please see “Executive and Director Compensation of Benson Hill.”

Director Compensation

Following the merger, non-employee directors of New Benson Hill will receive varying levels of compensation for their services as directors and members of committees of New Benson Hill’s board of directors.

We encourage you to read the merger agreement carefully and in its entirety. This section is not intended to provide you with any factual information about STPC or Benson Hill. Such information can be found elsewhere in this proxy statement/prospectus.

Terms of the Merger

Transaction Structure

STPC’s and Benson Hill’s boards of directors have approved the merger agreement. The merger agreement provides for the merger of Benson Hill with and into Merger Sub, a wholly-owned subsidiary of STPC, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC.

Merger Consideration

Each share of Benson Hill Preferred Stock issued and outstanding immediately prior to the effective time of the merger will be converted into a number of shares of Existing Benson Hill Common Stock in accordance with the Benson Hill charter (the “Benson Hill Preferred Conversion”). At the effective time of the merger, each outstanding share of Existing Benson Hill Common Stock, including shares of Existing Benson Hill Common Stock held by prior owners of Benson Hill Preferred Stock and Benson Hill Warrants, (in each case, other than shares owned by Benson Hill as treasury stock and dissenting shares) will be cancelled and converted into the right to receive (x) the number of shares of New Benson Hill Common Stock in a ratio (the “Exchange Ratio”) equal to: (a)(i)(A) $1.3 billion plus (B) the aggregate exercise price of all Benson Hill Options whether vested or unvested, outstanding immediately prior to the Effective Time divided by (ii) $10.00 divided by (b) the total number of shares of Existing Benson Hill Common Stock outstanding immediately prior to the effective time, expressed on a fully-diluted basis (including the number of Existing Benson Hill Common Stock issued or issuable upon the Benson Hill Preferred Conversion) and including the aggregate number of shares issuable upon the exercise of all Benson Hill Options, whether vested or unvested, outstanding immediately prior to the effective time in accordance with their respective terms, and (y) the applicable number of $14 Earn Out Shares and $16 Earn Out Shares, as set forth on the Allocation Schedule. A portion of the shares of New Benson Hill Common Stock comprising the merger consideration will be reserved for issuance upon exercise of certain outstanding options and warrants to purchase capital stock of Benson Hill that remain outstanding after the merger. Any resulting fractional shares of New Benson Hill Common Stock will instead be paid in cash in an amount equal to the fractional amount multiplied by $10.00. See “The Merger Agreement — Merger Consideration — Consideration; Conversion of Shares.”

Conversion of Shares; Exchange Procedures

The conversion of Existing Benson Hill Common Stock issued or issuable upon the Benson Hill Preferred Conversion will occur automatically immediately prior to the effective time of the merger. As soon as reasonably practicable after the effective time of the merger, New Benson Hill will exchange shares of Existing Benson Hill Common Stock (after taking effect of the Benson Hill Preferred Conversion) for merger consideration to be received in the merger pursuant to the terms of the merger agreement.

Unaudited Prospective Financial Information of Benson Hill

Benson Hill does not as a matter of course publicly disclose long-term forecasts or internal projections of their future performance, revenue, earnings, financial condition or other results. However, Benson Hill’s senior management prepared and provided to Benson Hill’s board of directors, Benson Hill’s financial advisors and STPC certain internal, unaudited prospective financial information in connection with the evaluation of the merger (the ‘‘Unaudited Prospective Financial Information’’). The Unaudited Prospective Financial Information is not included in this proxy statement/prospectus in order to induce any STPC stockholders to vote in favor of or against any proposals at the STPC Special Meeting. The Unaudited Prospective Financial

147

Information prepared by Benson Hill’s senior management was provided to STPC and its board as a component of its overall evaluation of Benson Hill, and is included in this proxy statement/prospectus on that account. The Unaudited Prospective Financial Information should not be considered public guidance. The inclusion of the Unaudited Prospective Financial Information should not be regarded as an indication that Benson Hill or any other recipient of this information considered — or now considers — it to be necessarily predictive of actual future results.

The Unaudited Prospective Financial Information is subjective in many respects and is thus susceptible to multiple interpretations and periodic revisions based on actual experience and business developments. As a result, there can be no assurance that the prospective results will be realized or that actual results will not be significantly higher or lower than estimated. Since the Unaudited Prospective Financial information covers multiple years, that information by its nature becomes less predictive with each successive year. Benson Hill’s management selected the length of the period for the Unaudited Prospective Financial Information of Benson Hill because Benson Hill’s management believes six years appropriately demonstrates a reasonable estimate of the Company’s future financial performance.

While presented in this proxy statement/prospectus with numeric specificity, the Unaudited Prospective Financial Information is forward-looking and based on numerous variables and assumptions that are inherently uncertain and may be beyond the control of Benson Hill’s senior management, including, among other things, the matters described in the sections entitled “Forward-Looking Statements; Market, Ranking and Other Industry Data,” “Risk Factors” and “Benson Hill’s Management’s Discussion and Analysis of Financial Condition and Results of Operations.” In preparing the assumptions associated with the Unaudited Prospective Financial Information, Benson Hill’s senior management relied on a number of factors, including their significant experience and observations regarding consumer, industry and market trends at the time such information and underlying assumptions were prepared. Benson Hill’s management and board of directors believe, and based on diligence conducted by STPC in its evaluation of Benson Hill and the merger, STPC’s management and board of directors believe, that the Unaudited Prospective Financial Information and the assumptions used to derive such financial information were prepared by Benson Hill’s senior management on a reasonable basis, reflected the best estimates and judgments of Benson Hill based on information available to senior management at the time of preparation (including in light of the risks and uncertainties described herein), and presented, to the best of Benson Hill senior management’s knowledge and belief, the expected course of action and the expected future financial performance of Benson Hill as of that date with respect to each item contained in the Unaudited Prospective Financial Information.

The Unaudited Prospective Financial Information does not take into account any events or circumstances occurring after the date on which it was prepared. However, applicable federal securities laws require registrants to make full and prompt disclosure of material facts, both favorable and unfavorable, regarding their financial condition, which obligation may extend to situations where management knows or has reason to know that previously disclosed projections no longer have a reasonable basis. The senior management of each of STPC and Benson Hill has considered whether the Unaudited Prospective Financial Information needed to be updated for circumstances and events occurring after the preparation of such information and, to the best of their knowledge and belief, determined there were no such circumstances or events that would result in a material change to the Unaudited Prospective Financial Information or that would result in the Unaudited Prospective Financial Information no longer having a reasonable basis. However, these projections are not fact and should not be relied upon as being necessarily indicative of future results, and readers of this proxy statement/prospectus are cautioned not to place undue reliance on the Unaudited Prospective Financial Information. Important factors that may affect actual results and cause the results reflected in the prospective financial information not to be achieved include, among other things, risks and uncertainties relating to Benson Hill’s business, industry performance, the regulatory environment and general business and economic conditions. The Unaudited Prospective Financial Information also reflects assumptions as to certain business decisions that are subject to change.

The financial projections contained in the Unaudited Prospective Financial Information were not prepared with a view toward public disclosure, nor were they prepared with a view toward compliance with GAAP, published guidelines of the SEC or the guidelines established by the Public Company Accounting Oversight Board for preparation and presentation of prospective financial information. Accordingly, none of STPC, WithumSmith+Brown, PC, STPC’s independent registered public accounting firm, and Ernst &

148

Young LLP, Benson Hill’s independent registered accounting firm, nor any other independent accountants, has compiled, examined or performed any procedures with respect to the financial projections contained herein, nor have they expressed any opinion or any other form of assurance on such projections or their achievability. The report of the independent registered public accounting firm for Benson Hill, Inc. contained in the audited financial statements for the year ended December 31, 2020, which is included in this proxy statement/prospectus, relates to historical financial information of Benson Hill, and such report does not extend to the financial projections included below and should not be read to do so.

BY INCLUDING THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION IN THIS PROXY STATEMENT/PROSPECTUS, NEITHER BENSON HILL NOR STPC UNDERTAKES ANY OBLIGATION, AND EACH OF THEM EXPRESSLY DISCLAIMS ANY RESPONSIBILITY, TO UPDATE OR REVISE, OR PUBLICLY DISCLOSE ANY UPDATE OR REVISION TO, THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION TO REFLECT CIRCUMSTANCES OR EVENTS, INCLUDING UNANTICIPATED EVENTS, THAT MAY HAVE OCCURRED OR THAT MAY OCCUR AFTER THE PREPARATION OF THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION, EVEN IN THE EVENT THAT ANY OR ALL OF THE ASSUMPTIONS UNDERLYING THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION ARE SHOWN TO BE IN ERROR OR CHANGE, IN EACH CASE, EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE FEDERAL SECURITIES LAWS. READERS OF THIS PROXY STATEMENT/​PROSPECTUS ARE CAUTIONED NOT TO PLACE UNDUE RELIANCE ON THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION SET FORTH BELOW AND NOT TO RELY ON SUCH FINANCIAL INFORMATION IN MAKING A DECISION REGARDING THE BUSINESS COMBINATION PROPOSAL, AS SUCH FINANCIAL INFORMATION MAY BE MATERIALLY DIFFERENT THAN ACTUAL RESULTS. NONE OF BENSON HILL, STPC NOR ANY OF THEIR RESPECTIVE AFFILIATES, OFFICERS, DIRECTORS, ADVISORS OR OTHER REPRESENTATIVES HAS MADE OR MAKES ANY REPRESENTATION TO ANY BENSON HILL STOCKHOLDER, STPC STOCKHOLDER OR ANY OTHER PERSON REGARDING ULTIMATE PERFORMANCE COMPARED TO THE INFORMATION CONTAINED IN THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION OR THAT FINANCIAL AND OPERATING RESULTS WILL BE ACHIEVED. STPC DOES NOT INTEND TO REFERENCE THE UNAUDITED PROSPECTIVE FINANCIAL INFORMATION IN ITS FUTURE PERIODIC REPORTS FILED UNDER THE EXCHANGE ACT.

Certain of the measures included in the Unaudited Prospective Financial Information may be considered non-GAAP financial measures. Due to the forward-looking nature of this information, specific quantifications of the amounts that would be required to reconcile such projections to GAAP measures are not available and Benson Hill believes it is not feasible to provide accurate forecasted non-GAAP reconciliations. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-GAAP financial measures as used by Benson Hill may not be comparable to similarly titled amounts used by other companies.

Estimated capital expenditures for fiscal years 2021, 2022 and 2023 reflect investments in UHP soybean derived ingredient for human food, yellow pea ingredients and Fresh segment.

The Unaudited Prospective Financial Information of Benson Hill was prepared using a number of assumptions, including the following assumptions that Benson Hill believed to be material:

•

The continued global expansion of the plant-based meat alternative markets, which is expected to exceed $140 billion in retail value over the next ten years, according to Kearney industry research.

•

The continued growth of the underlying protein ingredients market (serving the aforementioned plant-based meat alternative market), which Benson Hill’s senior management estimates reaching approximately $25 to $26 billion, and Benson Hill’s capture of approximately 3.5% of this market by 2027, resulting in Benson Hill achieving 2027 protein ingredients revenues for the human food market of approximately $1.0 billion.

•

89% of Benson Hill’s total revenues in 2027 are from proprietary soybean products that have already been developed and are listed in the chart on page 96 under “Near-Term Strategy.”

•

No significant change in Benson Hill’s current strategy regarding product development, areas of focus and marketing. Current proprietary soybean products already developed represent 94% of total Ingredient Segment revenues included in the Unaudited Prospective Financial Information. The other 6% represents new products that are expected to first realize revenues in 2026 and 2027.

•

Benson Hill’s Research and Development (R&D) costs increase as Benson Hill continues to invest in new products and new generations of existing products. Despite the continued level of investment in R&D, only 6% of new revenues from potential future innovations are included in the Unaudited Prospective Financial Information. Research and Development costs decrease as a percentage of revenues from 30% to 4% in 2021 to 2027 due primarily to increasing revenues from the existing products in the Near-Term Strategy described on page 96.

150

•

Benson Hill will be able to contract in 2021 with farmers for approximately 60,000 acres of proprietary soybean plantings in the 2021 crop season. In addition, Benson Hill will be able to contract and/or acquire harvested material from approximately 90,000 acres of non-proprietary yellow pea product for processing in its Dakota Ingredients business in 2021. Dakota Ingredients at near capacity can process approximately 90,000 acres annually, and remaining growth in contracted acres included in the Unaudited Prospective Financial Information is assumed to come primarily from incremental proprietary soybean acreage contracts with farmers. Revenue growth is driven primarily from increased contracted acreage of Benson Hill’s proprietary soybean products.

•

Product pricing is below that of current conventional competing products, the latter being more highly processed and more environmentally intensive.

•

Over time, Benson Hill’s ultra-high protein soybean products will be able to eliminate the need for more expensive energy and water intensive processing that is currently used to produce a market ready product resulting in lower cost of revenues and improved margins.

•

The Fresh Segment will continue to operate in a relatively stable market with limited year-over-year growth.

•

Capital expenditures through 2023 include the build out of the Fresh Segment Vero Beach, Florida facility, the build out of the leased Crop Accelerator facility and amounts needed to invest in the delivery of the integrated supply chain and processing partnerships to improve gross margins. Following 2023, capital expenditures is less than 5% of total revenues.

•

Benson Hill will be able to obtain sufficient production assets and manufacturing partners and assets to process its food and feed ingredients in accordance with its business plan to implement its integrated supply chain.

•

Benson Hill will be able to obtain sufficient funding whether by a transaction, debt financing, additional private equity funding, or some combination of the preceding sources.

The Unaudited Prospective Financial Information of Benson Hill does not assume the completion of the merger and related transactions.

Certain Financial Analysis

Comparable Public Companies

STPC’s board of directors primarily relied upon a comparable company analysis prepared by Goldman Sachs & Co. LLC (“Goldman”) and Credit Suisse Securities (USA) LLC (“CS”) in order to assess the value that the public markets would likely ascribe to New Benson Hill following a business combination with Benson Hill, and this analysis was presented to the STPC board of directors. The relative valuation analysis was based on selected publicly-traded companies (and one private company that has announced a proposed business combination with a publicly-traded special purposes acquisition company) categorized as either growth companies or mature companies. Within the growth company category, comparable companies were selected in the food technology, agricultural technology and biotechnology markets, and within the mature company category, comparable companies were selected in the agricultural technology and specialty ingredients markets (each further described below and together, the “Benchmark Companies”). The selected companies in each sector were chosen because they were determined by Goldman and CS to be the most relevant in their particular sector (but, for the avoidance of doubt, each of the selected companies is not necessarily a direct competitor of Benson Hill). These companies were selected as publicly-traded (or soon to be publicly-traded, pending completion of a proposed business combination) companies having businesses with similar end markets, business models, go-to-market strategies, ESG characteristics, forecasted margins and/or growth rates. While these companies may share certain characteristics that are similar to those of Benson Hill, the STPC board of directors recognized that no company was identical in nature to Benson Hill. All of the companies that met STPC’s criteria were included in the analysis.

The relative valuation analysis considered by the STPC board of directors was comprised of three groups of public companies (and one private company that has announced a proposed business combination with

151

a publicly traded special purposes acquisition company) categorized as growth companies and one group of public companies categorized as mature companies. The Benchmark Companies can be summarized as follows:

The Benchmark Companies categorized as growth companies were grouped as follows:

Food Technology.   These selected companies serve the same consumer demand trends as Benson Hill and have similar ESG characteristics.

Agricultural Technology.   These selected companies possess proprietary technology platforms and focus on the food / nutrition and health & wellness value chains.

Biotechnology.   These selected companies possess proprietary technology platforms and focus on the health & wellness end market.

The Benchmark Companies categorized as mature companies were grouped as follows:

Agricultural Technology or Specialty Ingredients.   These selected companies focus on the specialty ingredients markets and/or the food / nutrition and health & wellness value chains.

The metrics underlying the relative valuation analysis considered by the STPC board of directors was compiled by Goldman and CS using publicly available information, and consisted of the following:

STPC’s management does not have access to non-public information of any of the Benchmark Companies used for comparative purposes and metrics that were publicly available for certain Benchmark Companies were not necessarily ascertainable for all of them. Accordingly, a complete valuation analysis of

152

Benson Hill and the merger cannot rely solely upon a quantitative review of the comparable publicly traded companies, but involves complex considerations and judgments concerning differences in financial and operating characteristics of such companies, as well as other factors that could affect their value relative to that of Benson Hill. Therefore, the selected public companies analysis is subject to certain limitations. STPC’s management reviewed with the STPC board of directors, among other things, the estimated revenue compound annual growth rate percentage over the period from 2021 through 2023 and 2023 estimated gross margin with respect to each such selected comparable company. The percentages for the selected comparable companies and the median for each peer group, as of April 30, 2021, are summarized in the table below:

​	Revenue CAGR		Gross Margin
​	2021E – 2023E		2023E
Growth Companies	​	​	​	​
Food Technology	​	​	​	​
AeroFarms(1)	​	NM	​	19%
AppHarvest, Inc.(1)	​	163%	​	N/A
Beyond Meat, Inc.	​	39%	​	35%

Based on the review of these selected comparable companies as of April 30, 2021, the STPC board of directors concluded that Benson Hill’s estimated revenue compound annual growth rate percentage over the period from 2021 through 2027 of 50% (based upon Benson Hill’s estimated 2021, 2022, 2023, 2024, 2025, 2026 and 2027 revenues of $127 million, $161 million, $251 million, $348 million, $561 million, $862 million and $1,472 million, respectively, as described above in “— Unaudited Prospective Financial Information of Benson Hill”) and estimated gross margins for 2025, 2026 and 2027 of 38%, 43% and 48%, respectively (based

153

upon Benson Hill’s estimated 2025, 2026 and 2027 gross profits of $212 million, $372 million and $703 million, respectively, as described above in “— Unaudited Prospective Financial Information”) were attractive relative to the selected comparable companies, as well as the median for each peer group.

Using publicly available information, STPC management also reviewed with the STPC board of directors, among other things, the enterprise values (defined as market capitalization plus net debt plus minority investments minus unconsolidated investments) as multiples of revenue for estimated calendar years 2022 and 2023 with respect to each such selected comparable company and each peer group. The revenue multiples for the selected comparable companies and the median for each peer group, as of April 30, 2021, are summarized in the table below:

Based on the review of these selected comparable companies as of April 30, 2021, the STPC board of directors concluded that Benson Hill’s estimated enterprise values as a multiple of revenue for 2022 and 2023 of 8x and 5x, respectively (based upon Benson Hill’s estimated 2022 and 2023 revenues of $161 million and $251 million, respectively, as described above in “— Unaudited Prospective Financial Information of

154

Benson Hill”), were an attractive valuation relative to the estimated enterprise values as a multiple of revenue of such selected comparable companies, as well as the median for each peer group.

Using publicly available information, STPC management also reviewed with the STPC board of directors, among other things, the enterprise values as multiples of EBITDA for estimated calendar year 2023 (except with respect to the food technology comparable companies, for which multiples of EBITDA were evaluated for estimated calendar year 2024) with respect to each selected comparable company peer group. The range of EBITDA multiples for each of the selected comparable company peer groups, as of April 30, 2021, are summarized in the table below:

​	Enterprise Value / EBITDA
​	2023E
Growth Companies	​
Food Technology(1)	31x – 39x
Agricultural Technology	(2)
Biotechnology	(2)
Mature Companies	​
Agricultural Technology / Special Ingredients	13x – 23x

(1)

Excludes AeroFarms and reflects Enterprise Value / EBITDA for estimated calendar year 2024. Enterprise Value / EBITDA for the food technology comparable company peer group was evaluated for estimated calendar year 2024 instead of estimated calendar year 2023 because EBITDA estimates for many food technology comparable companies for estimated calendar year 2023 resulted in non-meaningful multiples given limited estimated EBITDA. EBITDA estimates for calendar year 2024 were used to reflect more normalized EBITDA multiples based on more meaningful EBITDA levels.

(2)

Cannot be calculated due to negative or limited estimated EBITDA.

Based on the review of these selected comparable company peer groups as of April 30, 2021, the STPC board of directors concluded that Benson Hill’s estimated enterprise value as a multiple of EBITDA for estimated calendar year 2026 of 6x (based upon Benson Hill’s estimated EBITDA of $239 million as described above in “— Unaudited Prospective Financial Information of Benson Hill”) was an attractive valuation relative to the estimated calendar year enterprise values as a multiple of EBITDA of such selected comparable company peer groups.

The STPC board of directors viewed Benson Hill’s estimated revenue compound annual growth rate percentage and long term gross profit margin as the most relevant operational measures on which to evaluate Benson Hill’s performance relative to comparable companies based on their belief that revenue growth coupled with gross profit margin growth are the appropriate metrics to evaluate a company in Benson Hill’s stage of growth. Furthermore, the STPC board of directors viewed Benson Hill’s enterprise value as a multiple of both near term revenue and longer term EBITDA as the most relevant valuation measures on which to evaluate Benson Hill’s value based on their belief that these multiples are the most prevalent and relevant metrics for the following sectors: (1) food technology; (2) agricultural technology; (3) biotechnology; and (4) Specialty Ingredients. The results of this analysis (as described above) supported the STPC board of directors’ determination, based on a number of factors, that the terms of the merger were fair to and in the best interests of STPC and its stockholders.

Background of the Merger

The terms of the merger agreement are the result of negotiations between STPC, Benson Hill and their respective representatives. The following is a brief description of the background of these negotiations.

STPC is a blank check company formed under the laws of the State of Delaware and was incorporated in Delaware on October 8, 2020. STPC was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses, with the intent to focus specifically on a combination with a target business in a sustainability

155

related industry, which includes, but is not limited to, clean energy and power (including generation, storage, smart grid technologies and hydrogen technologies and fuel cells), sustainable food and agriculture, transportation (including electric vehicles, mobility and fueling or charging infrastructure), resource management (including energy efficiency and carbon capture), environmental services (including waste management, pollution control, water and recycling) and technology enabled sustainable solutions (including supply chain management) in North America.

In October 2020, the Sponsor purchased 10,062,500 founder shares for an aggregate purchase price of $25,000, or approximately $0.003 per share. The Sponsor later transferred 40,000 founder shares to each of Desirée Rogers and C. Park Shaper, the independent directors.

On January 8, 2021, STPC completed its IPO of 40,250,000 units, at a price of $10.00 per unit, generating gross proceeds of $402,500,000 million, which included the exercise in full of the underwriters’ option to purchase an additional 5,250,000 units at the initial public offering price to cover over-allotments. Each unit consists of one (1) share of Class A Common Stock, par value $0.0001, and one-fourth (1/4) of one (1) warrant. Each whole warrant entitles the holder thereof to purchase one (1) share of Class A Common Stock at a price of $11.50 per share, subject to certain adjustments.

Concurrently with the completion of STPC’s IPO, the Sponsor purchased an aggregate of 6,553,454 Private Placement Warrants at a price of $2.00 per warrant, or $13,106,908 in the aggregate. Each whole Private Placement Warrant entitles the holder thereof to purchase one (1) share of Class A Common Stock at a price of $11.50 per share, subject to certain adjustments.

Of the proceeds received from the consummation of the IPO, the private placement purchases by the Sponsor and the sale of the Over-Allotment Units, $402,500,000 (or $10.00 per unit sold in the public offering) was deposited in the Company’s trust account.

Prior to the consummation of STPC’s IPO, neither STPC, nor anyone on its behalf, contacted any prospective target business or had any substantive discussions, formal or otherwise, with respect to a business combination with STPC.

Between January 8, 2021, the date of STPC’s IPO, and February 24, 2021, the date on which STPC entered into exclusivity with Benson Hill (as further described below), STPC initiated contact with more than 159 potential targets, including privately held assets and assets or divisions owned by four publicly traded companies. Of those potential targets, STPC had discussions with approximately 40 management teams. STPC also met with 77 investors and shareholders of potential targets and approximately 13 investment banks or advisors. STPC conducted additional due diligence with respect to approximately 77 potential targets (the “Potential Targets”) and then entered into 15 non-disclosure agreements with Potential Targets. Following this initial due diligence, STPC entered into substantive discussions leading to draft letters of intent being circulated with two of the Potential Targets, which are referred to herein as “Company A” and “Company B”.

With respect to Company A, discussions began following when the non-disclosure agreement was signed on January 8, 2021 and generally ended in late January when Company A decided to pursue a transaction with another party. With respect to Company B, discussions began in later January 2021 and generally ended a few weeks later in mid-February due to an inability to agree on mutually acceptable terms.

On January 8, 2021, in the course of STPC’s review of potential business combination targets, Craig Rohr of STPC contacted Matt Crisp of Benson Hill via email and arranged for an introductory telephone call to discuss Benson Hill’s business.

On January 11, 2021, Matt Crisp of Benson Hill and Michael Morgan, Eric Scheyer, Adam Daley, Craig Rohr and Dain DeGroff of STPC had an introductory call in which they discussed Benson Hill’s business and the SPAC business combination process. On that call, Benson Hill and STPC decided to enter into a non-disclosure agreement with respect to sharing of confidential information. The non-disclosure agreement was executed on January 12, 2021.

On January 13, 2021, in the course of regular ongoing conversations regarding STPC’s review of Potential Targets, Craig Rohr reached out to Sanjeev Krishnan of s2g Ventures, a stockholder and board member of Benson Hill, to discuss general market conditions and the SPAC business combination process,

156

including whether any portfolio companies of s2g Ventures could be viable business combination targets. In the context of this conversation, Mr. Rohr and Mr. Krishnan discussed Benson Hill’s business and suitability as a Potential Target at a high level.

On January 13, 2021, Dain DeGroff of STPC and a representative of Barclays Capital Inc. (“Barclays”) had a call in which they discussed Barclays’ engagement with Benson Hill as its strategic advisor and a potential timeline for a management meeting. During this call, the representative of Barclays gave Mr. DeGroff an update on general market conditions.

On February 2, 2021, in the course of regular ongoing conversations regarding STPC’s review of Potential Targets, Dain DeGroff, STPC’s Executive Vice President, M&A, reached out to Eric O’Brien of Fall Line, a stockholder of Benson Hill to discuss general market conditions and the SPAC business combination process, including whether any portfolio companies of Fall Line could be viable business combination targets. In the context of this conversation, Mr. DeGroff and Mr. O’Brien discussed Benson Hill’s business and suitability as a Potential Target at a high level.

On February 7, 2021, in the course of regular ongoing conversations regarding STPC’s review of Potential Targets, Mike Morgan reached out to David Krane of GV, a stockholder of Benson Hill to discuss general market conditions and the SPAC business combination process, including whether any portfolio companies of GV could be viable business combination targets. On February 12, 2021, Mike Morgan and David Krane again connected and discussed various topics, including Benson Hill’s business and the SPAC business combination process. In the context of this conversation, Mr. Morgan and Mr. Krane discussed Benson Hill’s business and suitability as a Potential Target at a high level.

Benson Hill has regularly engaged from time to time in a review of potential strategic alternatives, including additional fundraising from debt or equity sources, possible business combinations or an IPO. Benson Hill management also provided updates on its strategic process to the Benson Hill board of directors (the “Benson Hill Board”) through weekly or bimonthly meetings during the same period.

On October 19, 2020, Benson Hill engaged Winston & Strawn LLP (“Winston”) as its mergers and acquisitions and capital markets counsel.

On January 5, 2021 and January 29, 2021, the Benson Hill Board met to discuss outreach to potential SPAC partners. During this period, management of Benson Hill also became familiar with the general opportunities of potential business combinations with special purpose acquisition companies and consulted with Barclays regarding the structuring and potential benefits and risks associated with a transaction of that nature.

On January 14, 2021, Benson Hill engaged Barclays as its financial advisor.

From the time of entering into the non-disclosure agreement until an initial management meeting on February 10, 2021, various members of Benson Hill, STPC and Barclays would exchange emails and have calls to discuss logistics for the initial management meeting and various process related items.

On February 10, 2021, Benson Hill presented an initial management presentation to STPC. This included a preliminary outline of the possible sources and uses of a potential business combination transaction between Benson Hill and STPC.

On February 11, 2021, in the course of regular ongoing conversations regarding STPC’s review of Potential Targets, Craig Rohr reached out to Mark Cupta of Prelude Ventures, a stockholder and board member of Benson Hill to discuss general market conditions and the SPAC business combination process. In the context of this conversation, Mr. Rohr and Mr. Cupta discussed Benson Hill’s suitability as a Potential Target at a high level.

On February 16, 2021, Benson Hill and certain of STPC’s consultants held an introductory call so that the consultants could get a better understanding of Benson Hill’s operations.

On February 18, 2021, Barclays sent via email to STPC a process letter that outlined the proposed timeline for submitting letters of intent to Benson Hill. The process letter requested that letters of intent be submitted on February 22, 2021 and included certain items to address in the letter of intent, including

157

valuation, transaction structure, proposed PIPE sizing, sources and uses and other standard items for a transaction of this type. Separately, on February 18, 2021, Barclays sent via email to STPC an excel template for submitting due diligence requests.

Between February 18, 2021 and February 22, 2021, STPC had various calls with its board members, advisors and consultants to discuss the letter of intent, Benson Hill’s business, and valuation.

On February 22, 2021, STPC sent an initial draft preliminary term sheet to Benson Hill (as revised, the “Preliminary Term Sheet”). The pre-money equity valuation of Benson Hill in the Preliminary Term Sheet was $1.2 billion. To arrive at the valuation, STPC, in consultation with Goldman Sachs, as M&A advisor to STPC, and Credit Suisse, as capital markets advisor to STPC, evaluated Benson Hill’s financial forecasts provided in its management presentation and, as further validation of the valuation, reviewed the relative valuations of comparable companies (with such comparable companies described in greater detail above in the section titled “— Certain Financial Analysis”).

The Preliminary Term Sheet was negotiated directly between STPC, in consultation with Goldman Sachs and Credit Suisse, on the one hand, and Benson Hill, in consultation with Barclays, on the other hand. None of s2g Ventures, Fall Line, GV or Prelude Ventures were involved in the negotiation of the Preliminary Term Sheet, and STPC did not negotiate the term sheet with such persons.

Also on February 22, 2021, the Benson Hill Board met to discuss the letters and terms contained in the indications of interest from three (3) potential partners received between February 18, 2021 and February 22, 2021, including STPC’s initial draft of the Preliminary Term Sheet.

On February 23, 2021, Barclays sent a revised Preliminary Term Sheet to STPC. The revised draft generally addressed lock ups, governance, closing conditions, timing, expense reimbursement and included higher consideration to be paid to Benson Hill’s stockholders based on a pre-money equity valuation of $1.6 billion. In connection with providing a revised Preliminary Term Sheet to STPC, the Chief Executive Officer of Benson Hill contacted STPC in order to relay that its initial bid with consideration based on a $1.2 billion pre-money equity valuation was lower than those of the two (2) other potential partners and that the STPC bid would only be competitive with a valuation of $1.6 billion. STPC, in consultation with Goldman Sachs and Credit Suisse, determined that, subject to being able to perform diligence, a valuation of $1.6 billion was acceptable based on Benson Hill’s financial forecasts and the range of valuations of comparable companies (with such comparable companies described in greater detail above in the section titled “— Certain Financial Analysis”).

On February 23, 2021, STPC engaged Kirkland & Ellis LLP (“K&E”) as its mergers and acquisitions and capital markets counsel.

On February 23, 2021, STPC reviewed the term sheet with their financial advisors and sent a revised Preliminary Term Sheet back to Barclays, with a counteroffer on certain terms, such as the inclusion of options.

On February 24, 2021, Benson Hill sent a further revised Preliminary Term Sheet back to STPC. STPC found this acceptable, and STPC and Benson Hill executed the Preliminary Term Sheet. The Preliminary Term Sheet provided for, among other things, a pre-money equity valuation of Benson Hill of $1.6 billion, an agreement of certain shareholders and other stakeholders executing lock-up agreements, contemplation of registration rights, the right for the sellers to nominate seven individuals to the board of directors, the right of STPC to nominate two individuals to the board of directors, agreeing to adopt a new management equity compensation plan and a minimum cash condition requiring the sum of the proceeds from the PIPE Investment plus the funds in STPC’s trust account at closing to equal at least $325 million. In the Preliminary Term Sheet, STPC and Benson Hill agreed that they would negotiate with each other exclusively for 30 days unless they mutually agreed to end such exclusivity period early.

On February 24, 2021, STPC commenced confirmatory business due diligence and third party legal, financial, accounting, tax, information technology, insurance, benefits and food and agriculture industry trends due diligence, and participated in various discussions with representatives of Benson Hill.

Throughout the months of February and March and into April 2021, Benson Hill, STPC and their respective advisors participated in a number of due diligence telephone calls and exchanged due diligence

158

materials, including in the areas of legal, financial, information technology, tax, insurance, employee benefits and food and agriculture industry trends.

On March 1, 2021, K&E, counsel to STPC, spoke with Winston, counsel to Benson Hill, to discuss the timeline to execution of the definitive documentation, allocation of drafting responsibilities and certain other topics. At this meeting, the parties agreed that K&E would commence drafting the merger agreement for the potential business combination.

On March 3, 2021, STPC held a board meeting, during which the Preliminary Term Sheet was reviewed, a transaction status update was given, board members asked questions and discussed the terms and timeline of the transaction.

On March 4, 2021, the Benson Hill Board had a meeting, during which the transaction workstreams were discussed and Barclays provided a market update.

On March 12, 2021, K&E distributed to Winston an initial draft of the merger agreement for the potential business combination.

On March 15, 2021, members of STPC management received the initial diligence memorandum from K&E and subsequently corresponded with K&E regarding its legal diligence findings.

On March 17, 2021, members of Benson Hill management met with STPC management as part of a management due diligence session at Benson Hill’s headquarters in Missouri. Benson Hill management and STPC management also conducted on-site diligence at a third party owned soybean processing facility in Indiana.

On March 19, 2021, STPC and Benson Hill amended and restated the Preliminary Term Sheet (the “A&R Preliminary Term Sheet”), which extended the exclusivity period between STPC and Benson Hill, adjusted the pre-money equity valuation of Benson Hill from $1.6 billion to $1.3 billion, reduced the consideration to be received in accordance with the new valuation but contemplated inclusion of the Earn Out Shares and Sponsor Earn Out Shares mechanics and reduced the minimum cash closing condition to $225 million. These changes were made, by STPC, in consultation with CS and Goldman Sachs, and Benson Hill, in consultation with Barclays, because the market for initial business combinations with special purpose acquisition companies had softened considerably since agreeing to the prior valuation, and comparable companies to Benson Hill had similarly seen reduced market valuations during such period. STPC, in consultation with CS and Goldman Sachs, and Benson Hill, in consultation with Barclays, mutually agreed that the reduced valuation of $1.3 billion (but the corresponding reduction in consideration being subject to inclusion of the Earn Out Shares) was acceptable based on Benson Hill’s financial forecasts and the range of market valuations of comparable companies (with such comparable companies described in greater detail above in the section titled “— Certain Financial Analysis”).

On March 19, 2021, the Benson Hill Board met to discuss the transaction and market conditions related thereto and the revised deal terms.

On March 20, 2021, Winston provided K&E its initial comments to the merger agreement. The revised draft generally addressed tax withholding matters, representations and warranties, and covenants.

On March 23, 2021, STPC entered into a formal engagement letter with each of Goldman Sachs (in addition to its role as a mergers and acquisitions advisor), CS (in addition to its role as a capital markets advisors) and Barclays (together with Goldman Sachs and CS, the “Placement Agents”) to act as a Placement Agent with respect to the PIPE financing.

On April 1, 2021, K&E provided Winston a further revised merger agreement, which, among other things, (i) included the revised merger consideration amount reflecting the updated valuation and the corresponding mechanics related to the Earn Out Shares, in each case, pursuant to the A&R Preliminary Term Sheet, (ii) proposed inclusion of a representative to act on behalf of the existing Benson Hill shareholders with respect to determination of the vesting of the Earn Out Shares post-closing of the business combination (“Holder Representative”), and (iii) contained certain additional changes to the representations and warranties, covenants and closing conditions.

159

Between April 1, 2021 and May 8, 2021, representatives of STPC, representatives of Benson Hill, and advisors of STPC and Benson Hill exchanged numerous revised drafts of, and held various calls and meetings to discuss the investor management presentation to be provided to potential PIPE Investors, including the use of proceeds to be included therein, research analyst coverage and outstanding information requests related thereto. Beginning in late March 2021, representatives of the Placement Agents held conversations with potential PIPE Investors with respect to the PIPE Investment, including, in addition to referrals from the Placement Agents, existing investors in Benson Hill and STPC and members and affiliates of the Sponsor. K&E, Winston and Sidley Austin LLP (“Sidley”), counsel to the Placement Agents, exchanged drafts of the form of PIPE Agreement to be used in the PIPE Investment. On April 30, 2021, the form of PIPE Agreement was distributed to potential PIPE Investors with respect to the PIPE Investment. Between May 4, 2021 and May 7, 2021, K&E, Winston and Sidley collectively negotiated the terms and exchanged drafts of the form of PIPE Agreement and their respective representatives and advisors, including with respect to the funding mechanics, representations and warranties, registration rights and indemnification provisions set forth therein, and responded to follow-up questions and comments related thereto, particularly with respect to the Closing process and the expected timeline for consummating the business combination. During this time, the potential PIPE Investors conveyed to the Placement Agents their initial proposed subscription amounts. Due to strong investor demand, STPC, in consultation with its financial advisors, determined that it was in the best interest of the company to increase the size of the PIPE from $175 million to $225 million in light of the numerous opportunities to deploy the incremental capital into growth initiatives.

On May 7, 2021, a final version of the form of PIPE Agreement was distributed to the potential PIPE Investors, which reflected the outcome of negotiations between STPC, Benson Hill, and the potential PIPE Investors and their respective representatives and advisors. On May 7, 2021, the potential PIPE Investors that had chosen to participate in the PIPE Investment indicated their final subscription amounts and delivered executed PIPE Agreements to K&E.

On April 20, 2021, Winston provided K&E a further revised draft of the merger agreement, which among other things, (i) proposed issuing the Earn Out Shares to an escrow agent and entering into the Earn Out Shares Escrow Agreement, and (ii) contained certain additional changes to the representations and warranties.

On April 23, 2021, STPC and Benson Hill amended the A&R Preliminary Term Sheet solely to extend exclusivity to May 14, 2021. Prior to the extension, exclusivity was set to expire on April 24, 2021, which was not enough time for STPC and Benson Hill to finish negotiating and preparing the final documentation.

On May 5, 2021, STPC’s board held a virtual meeting to discuss the terms of the merger agreement and the merger. STPC’s board determined its approval would be given in a written consent in lieu of a special meeting.

On May 6, 2021, K&E delivered an updated legal due diligence memorandum to STPC management to close out certain open items and to reflect events that had occurred or to which K&E had been made aware since the date of the last memorandum.

On May 6, 2021, the Benson Hill Board held a virtual meeting to discuss the terms of the merger agreement and the merger. The Benson Hill Board adopted resolutions (i) determining that it is in the best interests of Benson Hill and its stockholders for Benson Hill to enter into the merger agreement and the ancillary agreements and (ii) adopting the merger agreement and approving Benson Hill’s execution and delivery of the merger agreement and the consummation of the merger.

Between April 30, 2021 and May 8, 2021 (the date the merger agreement and other definitive documentation was executed), K&E and Winston circulated several revised drafts of the merger agreement to, among other things, (i) contemplate that the Earn Out Shares not be issued to holders of Benson Hill options and that such holders of Benson Hill Options would instead receive Earn Out Awards, (ii) contemplate that the Holder Representative would be appointed by Benson Hill in the interim period before closing of the merger, (iii) contemplate increasing the PIPE Investment Amount to $225 million, commensurate with the minimum cash closing condition and (iv) finalize the representations and warranties, covenants and closing conditions.

160

On May 8, 2021, STPC’s board executed the written consent in lieu of a special meeting to approve the merger agreement, the merger and the PIPE Investment process and PIPE Agreements.

Recommendation of the Benson Hill Board of Directors and Reasons for the Merger

After consideration, the Benson Hill board of directors adopted resolutions determining that the merger, the merger agreement the other transactions contemplated by the merger agreement were advisable and in the best interests of Benson Hill and its stockholders, authorizing and approving the merger, the merger agreement and the transactions contemplated thereby, directing that the merger agreement be submitted to the holders of Existing Benson Hill Common Stock and preferred stock for consideration. The Benson Hill board of directors recommends that the holders of Benson Hill capital stock accept and approve the merger and adopt the merger agreement and the transactions contemplated thereby.

In reaching its decision to authorize and approve, and declare advisable, the merger agreement and resolving to recommend that Benson Hill stockholders adopt and approve the merger agreement and thereby accept and approve the merger and the other transactions contemplated by the merger agreement, the Benson Hill board of directors consulted with Benson Hill’s management, as well as its financial and legal advisors, and considered a number of factors, including its knowledge of Benson Hill’s business, operations, financial condition, earnings and prospects, and its knowledge of the financial and capital markets and the risks associated with funding the business plan through other means, including a potential IPO of Benson Hill. Among the various factors that the Benson Hill board of directors considered in favor of its decision are:

•

Other Alternatives.   It is the belief of the Benson Hill board of directors, after considering alternative opportunities from time to time, that the proposed merger represents the best potential transaction for Benson Hill to execute its business plan, create greater value for Benson Hill’s stockholders.

•

Advantages Over a Traditional IPO.   Prior to executing the merger agreement, the Benson Hill board of directors considered the alternative of a traditional IPO. The Benson Hill board of directors considered that the merger provided certain advantages over a traditional IPO. In particular, the Benson Hill board of directors considered that, based on available information at the time, including with respect to the conditions of the IPO market for companies of a similar size and industry as Benson Hill, the merger with STPC was likely to provide for a more time- and cost-effective means to capital with a higher likelihood of completion in light of the committed equity investments, greater valuation certainty and less dilution to Benson Hill’s existing stockholders and would provide potential investors with more extensive information about the prospects of Benson Hill.

•

Terms of the Merger Agreement.   The Benson Hill board of directors considered the terms and conditions of the merger agreement, including but not limited to the nature and scope of the closing conditions and the likelihood of obtaining any necessary regulatory approval, in addition to the transactions contemplated thereby, including the merger.

•

Size of Post-Combination Company.   The Benson Hill board of directors considered the merger implied pro forma enterprise value of approximately $1.35 billion for Benson Hill, providing Benson Hill’s stockholders with the opportunity to go forward with ownership in a public company with a larger market capitalization.

•

Access to Capital.   The Benson Hill board of directors expects that the merger will be a more time-and cost-effective means to access capital, repay a portion of its existing indebtedness and reduce leverage than other options considered, including an IPO.

•

Benefit from Being a Public Company.   The Benson Hill board of directors believes that under new public ownership it will have the flexibility and financial resources to pursue and execute a growth strategy to increase revenues and stockholder value and will benefit from being publicly traded, and can effectively utilize the broader access to capital and public profile that are associated with being a publicly traded company.

•

STPC Letter Agreement.   The Benson Hill board of directors considered that, pursuant to the Letter Agreement entered into with STPC, the Sponsor and each of STPC’s officers and directors, among other things, agreed to vote any Founder Shares held by them and any shares of STPC common

161

stock purchased during or after STPC’s IPO in favor of a proposed initial business combination and not to redeem such shares in connection with such a transaction and that the Sponsor, STPC’s officers and directors and their permitted transferees own at least 20% of its outstanding common stock entitled to vote thereon.

•

Subscription Agreements.   The Benson Hill board of directors considered that, pursuant to each Subscription Agreement between STPC and the PIPE Investors, the PIPE Investors have agreed to subscribe for and purchase, and STPC (and upon consummation of the merger, New Benson Hill) has agreed to issue and sell to the PIPE Investors, an aggregate of 22.5 million shares of Class A Common Stock of STPC for an aggregate purchase price of $225.0 million immediately following the effective time of the merger, on the terms and subject to the conditions set forth therein.

•

Support Agreements.   The Benson Hill board of directors considered that, concurrent with the execution of the merger agreement, certain holders representing greater than 60% of the outstanding shares of Existing Benson Hill Common Stock and Benson Hill Preferred Stock (determined on an as-converted basis) entered into the support agreements with STPC. Under the support agreements, the supporting holders agreed, among other things, to execute and deliver a written within three (3) business days after this proxy statement/prospectus is declared effective by the SEC, adopting the merger agreement, approving the merger and converting the Benson Hill Preferred Stock to Existing Benson Hill Common Stock effective immediately prior to, and conditioned upon, the effective time of the merger agreement.

•

Sponsor Lock-up Agreement.   In addition, the Sponsor and the holders of the Founder Shares have agreed to be subject to a lock-up of up to one year in respect of their Founder Shares.

•

Investor Rights Agreement.   The Benson Hill board of directors also considered that, as of the closing of the merger, STPC will enter into the Investor Rights Agreement (the “IRA”) among STPC, the Sponsor and certain other holders of New Benson Hill Common Stock (collectively, the “IRA Parties”). In accordance with the IRA, the IRA Parties and their permitted transferees will be entitled to, among other things, customary registration rights, including demand, piggy-back and shelf registration rights. Pursuant to the terms of the IRA, the Sponsor will have the ability to nominate two directors to the New Benson Hill board of directors (the “Investor Directors”). In the event that an Investor Director no longer serves on the New Benson Hill board of directors due to such director’s, death, disability, retirement, removal or resignation, during such Investor Director’s initial term, the Sponsor may designate a new individual to fill the vacancy. The IRA also provides that STPC will pay certain expenses relating to such registrations and indemnify the registration rights holders against (or make contributions in respect of) certain liabilities which may arise under the Securities Act.

•

For a more detailed description of the STPC Letter Agreement, the Subscription Agreements, the support agreements and the IRA, see the section titled “Other Agreements” beginning on page 188 of this proxy statement/prospectus.

The Benson Hill board of directors also considered the following negative factors:

•

Risk that the Merger may not be Completed.   The Benson Hill board of directors considered the risk that the merger might not be consummated in a timely manner or at all, due to a lack of stockholder approval or failure to satisfy various conditions to closing.

•

Impact on Reputation and Business if the Merger is not Completed.   The Benson Hill board of directors considered the possibility that the merger might not be completed and that there may be an adverse effect of the public announcement of the merger on Benson Hill’s reputation and business in the event the merger is not completed.

•

Expenses and Challenges.   The Benson Hill board of directors considered the expenses to be incurred in connection with the merger and related administrative challenges associated with combining the companies.

•

Costs of being a Public Company.   The Benson Hill board of directors considered the additional public company expenses and obligations that Benson Hill’s business will be subject to following the merger that it has not previously been subject to.

162

•

Restrictions on Operations of Benson Hill’s Business.   The Benson Hill board of directors considered the fact that, although Benson Hill will continue to exercise, consistent with the terms and conditions of the merger agreement, control and supervision over its operations prior to the completion of the merger, the merger agreement generally obligates Benson Hill, subject to STPC’s prior consent (which consent may not be unreasonably withheld, delayed or conditioned), to conduct its business in the ordinary course of business consistent with past practice and in accordance with specified restrictions, which might delay or prevent Benson Hill from undertaking certain business opportunities that might arise pending completion of the merger.

•

Interests of Benson Hill Executive Officers and Directors.   The Benson Hill board of directors considered the fact that certain executive officers and directors of Benson Hill have interests in the merger that may be different from, or in addition to, the interests of Benson Hill stockholders generally, including the manner in which they would be affected by the merger, and the other matters disclosed in the section titled “The Merger — Interests of Benson Hill Directors and Executive Officers in the Merger” beginning on page 166 of this proxy statement/prospectus.

•

Other Risks.   The Benson Hill board of directors considered various other risks associated with the combined organization and the merger, including the risks described in the section titled “Risk Factors.

The foregoing discussion of the factors considered by the Benson Hill board of directors is not intended to be exhaustive, but, rather, includes the material factors considered by the Benson Hill board of directors. In reaching its decision to adopt and approve, and declare advisable, the merger agreement, the merger and the other transactions contemplated by the merger agreement, the Benson Hill board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The Benson Hill board of directors considered all these factors as a whole, including discussions with, and questioning of, Benson Hill’s management and financial and legal advisors, and, overall, considered these factors to be favorable to, and to support, its determination.

The Benson Hill board of directors concluded that the potentially negative factors associated with the merger were outweighed by the potential benefits that it expected Benson Hill stockholders would receive as a result of the merger, including the belief of the Benson Hill board of directors that the merger would maximize the immediate value of shares of Benson Hill common stock and preferred stock and eliminate the risk and uncertainty affecting the future prospects of Benson Hill, including the potential execution risks associated with an IPO of Benson Hill common stock and preferred stock and pursuing its business plan as a public company. Accordingly, the Benson Hill board of directors determined that the merger and the other transactions contemplated by the merger agreement are advisable and in the best interests of Benson Hill and its stockholders, and authorizing and approving, and declaring advisable, the merger agreement, the merger and the other transactions contemplated by the merger agreement. The Benson Hill board of directors recommends that Benson Hill stockholders consent to the merger agreement and the merger and the transactions contemplated thereby.

Recommendation of the STPC Board of Directors and Reasons for the Merger

STPC’s board of directors, in evaluating the merger, consulted with STPC’s management and financial and legal advisors. In reaching its unanimous resolution (i) that the merger agreement and the transactions contemplated thereby are advisable and in the best interests of STPC and its stockholders and (ii) to recommend that the stockholders adopt the merger agreement and approve the merger and the transactions contemplated thereby, STPC’s board of directors considered a range of factors, including, but not limited to, the factors discussed below. In light of the number and wide variety of factors considered in connection with its evaluation of the merger, STPC’s board of directors did not consider it practicable to, and did not attempt to, quantify or otherwise assign relative weights to the specific factors that it considered in reaching its determination and supporting its decision. STPC’s board of directors viewed its decision as being based on all of the information available and the factors presented to and considered by it. In addition, individual directors may have given different weight to different factors. This explanation of STPC’s reasons for the merger and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under “Forward-Looking Statements; Market, Ranking and Other Industry Data” beginning on page 23 of this proxy statement/prospectus.

163

In approving the merger, STPC’s board of directors determined not to obtain a fairness opinion. The officers and directors of STPC have substantial experience in evaluating the operating and financial merits of companies from a wide range of industries and concluded that their experience and background, together with the significant experience and sector expertise of STPC’s financial advisors, enabled them to make the necessary analyses and determinations regarding the merger. In addition, STPC’s officers and directors and STPC’s advisors have substantial experience with mergers and acquisitions.

STPC’s board of directors considered a number of factors pertaining to the merger as generally supporting its decision to enter into the merger agreement and the transactions contemplated thereby, including, but not limited to, the following material factors:

•

Growth Prospects.   The board of directors reviewed financial and operational information provided to STPC, including certain Unaudited Prospective Financial Information of Benson Hill, and considered Benson Hill to be a market leader in an attractive and growing industry with an already successful business and with strong growth prospects within the agri-food industry and high quality and experienced venture capital and strategic investors;

•

Large Addressable Market.   Benson Hill competes in the plant-based meat substitute segment, a market forecasted to be in excess of $140 billion by 2030 according to industry research, and within the broader agri-food industry estimated at $5 trillion according to McKinsey;

•

Economics.   Some of the factors STPC’s board of directors considered include Benson Hill having the first-mover advantage in the fast growing plant based protein ingredient space and Benson Hill having a highly attractive growth profile driven primarily by growth in Benson Hill’s existing products. STPC’s board of directors also considered the strong near-term visibility of Benson Hill’s forecast;

•

Due Diligence.   Due diligence examinations of Benson Hill and discussions with Benson Hill’s management and STPC’s financial and legal advisors concerning STPC’s due diligence examination of Benson Hill;

•

Financial Condition.   STPC’s board of directors also considered factors such as Benson Hill’s historical financial results, outlook, financial plan and debt structure, as well as the financial profiles of publicly traded companies in the agri-food industry and adjacent markets and certain relevant information with respect to companies that had been acquisition targets or received equity financings in transactions similar to the merger. In considering these factors, STPC’s board of directors reviewed Benson Hill’s recent growth in certain key financial metrics (including certain operational metrics), the current prospects for growth if Benson Hill achieved its business plans and various historical and current balance sheet items for Benson Hill. In reviewing these factors, along with the Unaudited Prospective Financial Information and operational information of Benson Hill, STPC’s board of directors noted that Benson Hill was well-positioned in its industry for strong future growth;

•

Experienced and Proven Management Team.   Benson Hill has a strong management team and the senior management of Benson Hill intend to remain with New Benson Hill in the capacity of officers and/or directors, which will provide helpful continuity in advancing Benson Hill’s strategic and growth goals;

•

Lock Up.   The Chief Executive Officer and certain other officers of Benson Hill have agreed to be subject to a six-month lock up in respect of their New Benson Hill Option awards, and certain other significant Pre-Closing Holders have agreed to be subject to a six-month lock up in respect of their shares of New Benson Hill Common Stock;

•

Other Alternatives.   STPC’s board of directors believes, after a thorough review of other business combination opportunities reasonably available to STPC, that the proposed merger represents the best potential business combination for STPC and the most attractive opportunity for STPC’s management to accelerate its business plan based upon the process utilized to evaluate and assess other potential acquisition targets, and STPC’s board of directors’ belief that such process has not presented a better alternative;

•

Negotiated Transaction.   The financial and other terms of the merger agreement and the fact that such terms and conditions are reasonable and were the product of arm’s length negotiations between STPC and Benson Hill; and

164

•

Merger Consideration.   The consideration to be paid to holders of Benson Hill Common Shares will include approximately 17.6 million Earn Out Shares that will only vest in the event New Benson Hill Common Stock trades at specified thresholds prior to the third anniversary of the closing of the merger.

STPC’s board of directors also considered a variety of uncertainties and risk and other potentially negative factors concerning the merger including, but not limited to, the following:

•

Macroeconomic Risks.   Macroeconomic uncertainty and the effects it could have on the combined company’s revenues;

•

Redemption Risk.   The potential that a significant number of STPC stockholders elect to redeem their shares prior to the consummation of the merger and pursuant to STPC’s Existing Charter, which would potentially make the merger more difficult or impossible to complete;

•

Stockholder Vote.   The risk that STPC’s stockholders may fail to provide the respective votes necessary to effect the merger;

•

Closing Conditions.   The fact that the completion of the merger is conditioned on the satisfaction of certain closing conditions that are not within STPC’s control;

•

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

•

Listing Risks.   The challenges associated with preparing Benson Hill, a private entity, for the applicable disclosure and listing requirements to which New Benson Hill will be subject to as a publicly traded company on the NYSE;

•

Benefits May Not Be Achieved.   The risks that the potential benefits of the merger may not be fully achieved or may not be achieved within the expected timeframe;

•

Liquidation of STPC.   The risks and costs to STPC if the merger is not completed, including the risk of diverting management focus and resources from other business combination opportunities, which could result in STPC being unable to effect a business combination by January 8, 2023;

•

Costs Savings and Growth Initiatives May Not be Achieved.   The risk that the cost savings and growth initiatives may not be fully achieved or may not be achieved within the expected timeframe;

•

No Third-Party Valuation.   The risk that STPC did not obtain a third-party valuation or fairness opinion in connection with the merger;

•

STPC Stockholders Receiving a Minority Position in Benson Hill.   The risk that STPC stockholders may hold a minority position in New Benson Hill; and

•

Fees and Expenses.   The fees and expenses associated with completing the merger.

In addition to considering the factors described above, STPC’s board of directors also considered other factors including, without limitation:

•

Interests of Certain Persons.   Some officers and directors of STPC may have interests in the merger. See the section titled “— Interests of STPC Directors and Executive Officers in the Merger” beginning on page 166 of this proxy statement/prospectus.

•

Other Risks Factors.   Various other risk factors associated with the business of Benson Hill, as described in the section entitled “Risk Factors” beginning on page 26 of this proxy statement/prospectus.

STPC’s board of directors concluded that the potential benefits that it expected STPC and its stockholders to achieve as a result of the merger outweighed the potentially negative and other factors associated with the merger. STPC’s board of directors also noted that the STPC stockholders would have a substantial economic interest in the combined company (depending on the level of STPC stockholders that sought redemption of their Class A Common Stock into cash), with all existing STPC stockholders expected to hold an aggregate of approximately 24.3% of the New Benson Hill Common Stock outstanding upon completion of the merger assuming no STPC stockholders redeem their Class A Common Stock for

165

cash. Accordingly, STPC’s board of directors unanimously determined that the merger and the transactions contemplated by the merger agreement, were advisable and in the best interests of STPC and its stockholders.

Interests of Benson Hill Directors and Executive Officers in the Merger

Certain of Benson Hill’s executive officers and directors may have interests in the merger that may be different from, or in addition to, the interests of Benson Hill’s stockholders. The members of the Benson Hill board of directors were aware of and considered these interests to the extent that such interests existed at the time, among other matters, when they approved the merger agreement and recommended that Benson Hill stockholders consent to the adoption of the merger agreement and the approval of the merger and the other transactions contemplated thereby. These interests include, among other things:

Benson Hill’s executive officers are expected to become the executive officers of Benson Hill upon consummation of the merger. Specifically, the following individuals who are currently executive officers of Benson Hill will become officers of New Benson Hill upon the consummation of the merger, serving in the offices set forth opposite their names:

Name	Office
Matthew Crisp	Chief Executive Officer
DeAnn Brunts	Chief Financial Officer
Yevgeny Fundler	Chief Legal Officer and Corporate Secretary
Jason Bull	Chief Technology Officer
Bruce Bennett	President of Ingredients

Interests of STPC Directors and Executive Officers in the Merger

In considering the recommendation of the board of directors of STPC to vote in favor of approval of the Business Combination Proposal, the Charter Proposals and the other proposals, stockholders should keep in mind that certain members of the board of directors and executive officers of STPC and the Sponsor, including their directors and executive officers, have interests in such proposals that are different from, or in addition to, those of STPC stockholders generally. In particular:

•

If the merger or another business combination is not consummated by January 8, 2023, STPC will cease all operations except for the purpose of winding up, redeeming 100% of the outstanding Class A Common Stock for cash and, subject to the approval of its remaining stockholders and its board of directors, dissolving and liquidating. In such event, the 10,062,500 Founder Shares held by the Sponsor and two of our directors, which were acquired for an aggregate purchase price of $25,000 prior to STPC’s IPO, would be worthless because the holders are not entitled to participate in any redemption or distribution with respect to such shares. Such shares had an estimated aggregate market value of $ based upon the closing price of $     per public share on the NYSE on          , 2021, the STPC record date.

•

The Sponsor purchased an aggregate of 6,553,454 Private Placement Warrants from STPC for an aggregate purchase price of $13,106,908 (or $2.00 per warrant) in a private placement. These purchases took place on a private placement basis simultaneously with the consummation of STPC’s IPO. The proceeds STPC received from these purchases were placed in the Trust Account. Such warrants had an estimated aggregate value of $ based on the closing price of $ per public warrant on the NYSE on           , 2021, the STPC record date. The Private Placement Warrants will become worthless if STPC does not consummate a business combination by January 8, 2023.

•

If STPC is unable to complete a business combination within the required time period, Sponsor will be personally liable under certain circumstances described herein to ensure that the proceeds in the Trust Account are not reduced by the claims of target businesses or claims of vendors or other entities that are owed money by STPC for services rendered or contracted for or products sold to STPC. If STPC consummates a business combination, on the other hand, STPC will be liable for all such claims.

•

Sponsor, STPC’s officers and directors, and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on STPC’s behalf, such

166

as identifying and investigating possible business targets and business combinations. However, if STPC fails to consummate a business combination within the required period, they will not have any claim against the Trust Account for reimbursement. Accordingly, STPC may not be able to reimburse these expenses if the merger or another business combination, are not completed by January 8, 2023.

•

If STPC is able to complete a business combination within the required time period, the Sponsor, its affiliates and STPC’s independent directors may receive a positive return on the 10,062,500 Founder Shares, which were acquired by Sponsor for an aggregate purchase price of $25,000 prior to STPC’s IPO, and/or the 6,553,454 Private Placement Warrants, which were acquired for an aggregate purchase price of approximately $13.1 million concurrently with completion of STPC’s IPO, even if the holders of Class A Common Stock experience a negative return on their investment in the Class A Common Stock after consummation of the merger.

The continued indemnification of current directors and officers and the continuation of directors’ and officers’ liability insurance.

Satisfaction of 80% Test

It is a requirement under STPC’s Existing Charter that any business acquired by STPC have a fair market value equal to at least 80% of the balance of the funds in the trust account (excluding the amount of any deferred underwriting discounts and commissions held in trust and taxes payable on the interest earned on the Trust Account) at the time of the execution of a definitive agreement for an initial business combination. Based on the financial analysis of Benson Hill generally used to approve the transaction, as discussed under “Certain Financial Analysis” above, the STPC board of directors determined that this requirement was met. The board determined that the consideration being paid in the Merger, which amount was negotiated at arms-length, was fair to and in the best interests of STPC and its stockholders and appropriately reflected Benson Hill’s value. In reaching this determination, the board concluded that it was appropriate to base such valuation in part on qualitative factors such as management strength and depth, competitive positioning, customer relationships, and technical skills, as well as quantitative factors such as Benson Hill’s historical growth rate and its potential for future growth in revenue and profits. The STPC Board believes that the financial skills and background of its members qualify it to conclude that the acquisition of Benson Hill met this requirement.

167

REGULATORY APPROVAL REQUIRED FOR THE MERGER

Completion of the merger is subject to regulatory approval under the HSR Act. STPC and Benson Hill agreed to use their reasonable best efforts to obtain required regulatory approval under the HSR Act.

Under the HSR Act, and related rules, the transactions may not be completed until notifications have been filed with and certain information has been furnished to the Antitrust Division and the FTC and all statutory waiting period requirements have been satisfied. STPC and Benson Hill filed Notification and Report Forms with the Antitrust Division and the FTC on May 21, 2021. The waiting period expired at 11:59 p.m. (ET) on June 21, 2021.

At any time before or after the completion of the merger, the Antitrust Division or the FTC could take action under the U.S. antitrust laws, including seeking to prevent the merger, to rescind the merger or to clear the merger subject to the divestiture of assets of STPC or Benson Hill or subject the transactions to other remedies. In addition, U.S. state attorneys general could take action under the antitrust laws as they deem necessary or desirable in the public interest including without limitation seeking to enjoin the completion of the transactions or permitting completion subject to the divestiture of assets of STPC or Benson Hill or other remedies. Private parties may also seek to take legal action under the antitrust laws under some circumstances. There can be no assurance that a challenge to the transactions on antitrust grounds will not be made or, if such challenge is made, that it would not be successful.

There can be no assurances that the regulatory approval discussed above will be received on a timely basis, or as to the ability of STPC and Benson Hill to obtain the approval on satisfactory terms or the absence of litigation challenging such approvals.

168

ACCOUNTING TREATMENT

The merger will be accounted for as a reverse recapitalization in accordance with GAAP. Under this method of accounting, STPC will be treated as the “acquired” company for accounting purposes and the business combination will be treated as the equivalent of Benson Hill issuing stock for the net assets of STPC, accompanied by a recapitalization. The net assets of STPC will be stated at historical cost, with no goodwill or other intangible assets recorded.

Benson Hill has been determined to be the accounting acquirer based on evaluation of the following facts and circumstances:

•

Benson Hill’s existing stockholders will have the greatest voting interest in the combined entity after giving effect to the merger under the no redemption and maximum redemption scenarios with over 65.3% voting interest in the no redemption scenario and 80.8% voting interest in the maximum redemption scenario, in each case;

•

After giving effect to the merger, the largest individual minority stockholder of the combined entity will be an existing stockholder of Benson Hill;

•

Benson Hill’s existing directors and individuals designed by existing Benson Hill stockholders will represent the majority of the New Benson Hill board of directors;

•

Benson Hill’s senior management will be the senior management of New Benson Hill; and

•

Benson Hill is the larger entity based on historical revenue and has the larger employee base.

Other factors were considered, including the purpose and intent of the merger, noting that the preponderance of evidence as described above is indicative that Benson Hill is the accounting acquirer in the merger.

169

PUBLIC TRADING MARKETS

The Class A Common Stock is listed on the NYSE under the symbol “STPC.” STPC’s warrants are listed on the NYSE under the symbol “STPC WS.” STPC’s units are listed on the NYSE under the symbol “STPC.U.” Following the merger, New Benson Hill Common Stock (including common stock issuable in the merger) and public warrants will be listed on the NYSE under the symbols “BHIL” and “BHIL WS,” respectively.

170

THE MERGER AGREEMENT

This section describes the material terms of the merger agreement. The description in this section and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the complete text of the merger agreement, a copy of which is attached as Annex A to this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. You are encouraged to read the merger agreement carefully and in its entirety. This section is not intended to provide you with any factual information about STPC or Benson Hill. Such information can be found elsewhere in this proxy statement/prospectus.

Effects of the Merger

As a result of the merger, Merger Sub will merge with and into Benson Hill, with Benson Hill surviving the merger as a wholly-owned subsidiary of STPC. The certificate of incorporation attached to the certificate of merger set forth in Exhibit G to the merger agreement will be the certificate of incorporation of the surviving company. The certificate of incorporation and bylaws of STPC will be in the form as set forth in Exhibit J to the merger agreement.

Merger Consideration

Under the terms of the merger agreement, immediately prior to the effective time of the merger, each share of Benson Hill Preferred Stock issued and outstanding immediately prior to the effective time of the merger will be converted into a number of shares of Existing Benson Hill Common Stock in accordance with the Benson Hill charter (the “Benson Hill Preferred Conversion”).

At the effective time of the merger, each outstanding share of Existing Benson Hill Common Stock, including common stock held by prior owners of Benson Hill Preferred Stock, and Benson Hill Warrants, (in each case, other than shares owned by Benson Hill as treasury stock and dissenting shares) will be cancelled and converted into the right to receive (x) the number of shares of New Benson Hill Common Stock in a ratio (the “Exchange Ratio”) equal to: (a)(i)(A) $1.3 billion plus (B) the aggregate exercise price of all Benson Hill Options whether vested or unvested, outstanding immediately prior to the effective time divided by (ii) $10.00 divided by (b) the total number of shares of Existing Benson Hill Common Stock outstanding immediately prior to the effective time, expressed on a fully-diluted basis (including the number of Existing Benson Hill Common Stock issued or issuable upon the Benson Hill Preferred Conversion) and including the aggregate number of shares issuable upon the exercise of all Benson Hill Options, whether vested or unvested, outstanding immediately prior to the effective time in accordance with their respective terms, and (y) the applicable number of $14 Earn Out Shares and $16 Earn Out Shares, as set forth on the Allocation Schedule. A portion of the 130,000,000 shares of New Benson Hill Common Stock will be reserved for issuance upon exercise of certain outstanding options and warrants to purchase capital stock of Benson Hill that remain outstanding after the merger. Any resulting fractional shares of New Benson Hill Common Stock will instead be paid in cash in an amount equal to the fractional amount multiplied by $10.00. In addition to the foregoing, Earn Out Awards will be granted under the New Incentive Plan (as defined in the Merger Agreement) to certain holders of Benson Hill Options. The number of Earn Out Shares and Earn Out Awards may be adjusted prior to Closing on a one-for-one basis, such that the number of Earn Out Awards will be decreased by any increase in Earn Out Shares to be issued, pursuant to the terms and subject to the conditions set forth in the merger agreement.

In addition, as of the effective time, each Benson Hill Option, whether vested or unvested, that is outstanding immediately prior to the effective time shall be assumed and converted into an STPC Option to purchase a number of shares of New Benson Hill Common Stock equal to the number of shares of Existing Benson Hill Common Stock subject to such Benson Hill Option immediately prior to the effective time multiplied by the Exchange Ratio, and rounded down to the nearest whole share, and at an exercise price per share of STPC Common Stock equal to the exercise price per share of Benson Hill common stock subject to such Benson Hill Option divided by the Exchange Ratio, and rounded up to the nearest whole cent.

Earn Out consideration.   Upon consummation of the merger, STPC will (a) also issue or cause to be issued to an escrow agent to be hold on behalf of the persons who hold one or more Benson Hill Common

171

Shares, Benson Hill Preferred Stock or Benson Hill Warrants (collectively, the “Earn Out Recipients”)of Benson Hill an aggregate of 17,562,680 restricted shares of New Benson Hill Common Stock (subject to vesting, forfeiture and certain other restrictions (including on transfer) set forth in the merger agreement (the “Earn Out Shares”)) and (b) will grant or cause to be granted to certain holders of Benson Hill Options a number of incentive equity awards with an equivalent value of 2,037,320 New Benson Hill Common Shares (the “Earn Out Awards”). With respect to the Earn Out Shares: (i) one-half (1/2) of the Earn Out Shares will vest if the dollar volume-weighted average closing price of the New Benson Hill common stock is greater than or equal to $14.00 over any 20 trading days (as defined in the merger agreement) within any 30 consecutive trading day period and (ii) one-half (1/2) of the Earn Out Shares will vest if the dollar volume-weighted average closing price of the New Benson Hill Common Stock is greater than or equal to $16.00 over any 20 trading days within any 30 consecutive trading day period, in each case, prior to the expiry of three (3) years from the closing of the merger (the “Earn Out Period”). In addition, if there is a sale of STPC prior to the expiration of the Earn Out Period that will result in the holders of New Benson Hill Common Stock receiving a price per share or implied price per share equal to or in excess of the applicable price per share thresholds described above, then Earn Out Shares will vest in connection with such sale of New Benson Hill in the manner set forth in the merger agreement. The Earn Out Awards will be subject to the same vesting terms and conditions as the Earn Out Shares, and the number of Earn Out Shares and Earn Out Awards are subject to adjustment such that if Benson Hill Options are forfeited in the interim period prior to the Closing, the number of Earn Out Shares to be issued will be increased by the corresponding decrease in the number of Earn Out Awards to be granted. In no event will the number of New Benson Common Shares issued as Earn Out Shares or being reserved for or subject to the Earn Out Awards granted exceed 19,600,000 New Benson Hill Common Shares in the aggregate.

The aforementioned conversions shall happen automatically.

Closing and Effective Time of the Merger

The closing of the merger shall take place at 10:00 a.m., Central time (i) at the offices of Kirkland & Ellis LLP, 609 Main Street, Houston, Texas 77002 or (ii) by electronic exchange of executed documents, on the date which is three (3) business days after the first date on which all of the closing conditions have been satisfied or waived (other than those conditions that by their terms are to be satisfied at the closing, but subject to the satisfaction or waiver thereof) or such other time and place as STPC and Benson Hill may mutually agree. See “The Merger Agreement — Conditions to the Merger” beginning on page 184 for a more complete description of the conditions that must be satisfied prior to closing.

On the date of the closing STPC and Benson Hill will effect the merger by filing a certificate of merger with the Secretary of State of the State of Delaware, and the merger will become effective at the time the certificate of merger has been accepted for filing by the Secretary of State of the State of Delaware or at such later time as may be agreed by STPC and Benson Hill in writing and specified in such certificate of merger in accordance with the relevant provisions of the DGCL. The time at which the merger becomes effective is sometimes referred to in this proxy statement/prospectus as the “effective time.”

As of the date of this proxy statement/prospectus, the parties expect that the merger will be effective during the third quarter of 2021. However, there can be no assurance as to when or if the merger will occur.

If the merger is not completed by February 28, 2022 (the “termination date”) (subject to certain extensions required as a result of delays related to obtaining consents or approvals from government authorities or the NYSE), the merger agreement may be terminated by either STPC or Benson Hill unless the parties mutually agree to extend the termination date. A party may not terminate the merger agreement pursuant to the provision described in this paragraph if the failure of the closing to occur by the termination date is due primarily to the failure of the party seeking to terminate the merger agreement to fulfil any obligations of such party set forth in the merger agreement. See “The Merger Agreement — Termination” beginning on page 185.

This summary and the copy of the merger agreement attached to this proxy statement/prospectus as Annex A are included solely to provide investors with information regarding the terms of the merger agreement. They are not intended to provide factual information about the parties or any of their respective subsidiaries or affiliates.

The Holder Representative will be given the full power and authority to take any and all actions on behalf of the Pre-Closing Holders that are necessary, appropriate or desirable to carry out all of the duties, responsibilities and obligations of the Holder Representative under the merger agreement. Any action taken or not taken or decisions, communications or writings made, given or executed by the Holder Representative with respect to all such matters, for or on behalf of any Pre-Closing Holder, will be deemed to be an action taken or not taken or decisions, communications or writings made, given or executed by such Pre-Closing Holder, and any notice or communication delivered to the Holder Representative under the merger agreement is deemed to have been delivered to all the Pre-Closing Holders.

Reasons for Proposed Charter Amendments

Elimination of Class B Common Stock (Proposal No. 2)

STPC’s Existing Charter contains provisions regarding the conversion of Class B Common Stock and anti-dilution protections in respect of Class B Common Stock. STPC’s Existing Charter also requires the affirmative vote of the holders of a majority of the shares of Class B Common Stock in order to make any amendment that would alter or change the powers, preferences or other rights of the holders of Class B Common Stock. The Proposed Charter eliminates Class B Common Stock and any rights of holders thereof. Following the merger, all shares of Class B Common Stock will have converted into Class A Common Stock and the protections afforded the Class B Common Stock while STPC was a special purpose acquisition company will no longer be necessary. STPC’s board of directors believes that the provisions relating to the Class B Common Stock will no longer be relevant to New Benson Hill and should be eliminated.

Amendments to Waiver of Corporate Opportunities (Proposal No. 3)

STPC’s Existing Charter has no specific provision regarding when an amendment to the waiver of corporate opportunities is effective. The Proposed Charter provides that no alteration, amendment,

192

addition to or repeal of the provisions of the Proposed Charter that relates to the waiver of corporate opportunities or adoption of any provision of the Proposed Charter (including any designation of preferred stock of New Benson Hill) inconsistent with such provisions will eliminate or reduce such provisions in respect of any business opportunity first identified or any other matter occurring, or any cause of action, suit or claim that, but for such provisions, would accrue or arise, prior to such alteration, amendment, addition repeal or adoption.

In addition, the Proposed Charter includes several clarificatory amendments to the Corporate Opportunity provision, including that the waiver of corporate opportunity applies to the affiliates of officers and directors and that limitations on the waiver of corporate opportunity do not apply to circumstances where a director or officer cannot refer an opportunity to New Benson Hill without violating a separate legal obligation. STPC’s board of directors believes that these amendments provide important and necessary clarifications to the scope of the waiver of corporate opportunity and in particular that it is important to clarify that any future amendment of provisions of the Proposed Charter relating to the waiver of corporate opportunities will not retroactively affect any action a director may take in reliance on such waiver.

Supermajority Provisions of the Charter and Bylaws (Proposal No. 4)

Under STPC’s Existing Charter, the affirmative vote of the holders of at least a majority of the voting power of all then-outstanding capital stock entitled to vote generally in the election of directors, voting together as a single class, is required to amend the bylaws or charter provisions (other than the requirement that any amendment to Article IX of the Existing Charter (Business Combination Requirements; Existence)) prior to the consummation of the initial “business combination” be approved by the affirmative vote of the holders of at least 65% of all then-outstanding shares of the common stock. New Benson Hill’s Proposed Charter will provide that, prior to           , 2024, the affirmative vote of at least 662∕3% of the voting power of the outstanding shares of capital stock entitled to vote thereon, voting together as a single class, shall be required to (A) adopt, amend or repeal the bylaws or (B) to amend or repeal Article V (Board of Directors), Article VI (Amendment of the Governing Documents) Article VII (Stockholder Action), Article VIII (Limitation of Director Liability and Indemnification), Article IX (Business Combinations), Article X (Corporate Opportunity), Article XI (Forum Selection) or Article XII (Miscellaneous) of the Proposed Charter.

Replacement of the Existing Charter (Proposal No. 5)

STPC’s Existing Charter will be amended and replaced in its entirety with the Proposed Charter. Conditioned upon the approval of Proposals No. 2 through No. 4, Proposal No. 5 provides approval for the Proposed Charter, which includes approval of all other changes in the Proposed Charter and related clean up changes, as well as the removal of provisions of STPC’s Existing Charter that will no longer be relevant, in connection with replacing the Existing Charter with the Proposed Charter, including the elimination of Article IX (Business Combination Requirements) and Article XIII (Application of DGCL Section 203) and changing STPC’s name from “Star Peak Corp II” to “Benson Hill, Inc.” as of the closing of the merger.

Anti-Takeover Effects of the Proposed Charter and Certain Provisions of Delaware Law

The Proposed Charter will contain and the DGCL contains provisions that are intended to enhance the likelihood of continuity and stability in the composition of our board of directors. These provisions are intended to avoid costly takeover battles, reduce our vulnerability to a hostile change of control and enhance the ability of the board of directors to maximize stockholder value in connection with any unsolicited offer to acquire New Benson Hill. However, these provisions may have an anti-takeover effect and may delay, deter or prevent a merger or acquisition of New Benson Hill by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of common stock held by stockholders. For more information, see “Description of New Benson Hill Capital Stock — Anti-Takeover Effects of New Benson Hill’s Proposed Charter and Bylaws and Certain Provisions of Delaware Law” beginning on page 235.

193

Vote Required for Approval

Approval of the Charter Proposals requires the affirmative vote of the holders of a majority of the then-outstanding shares of STPC common stock, voting together as a single class, and the affirmative vote of the holders of a majority of the then-outstanding shares of Class B Common Stock, voting separately as a single class. The merger is conditioned upon the approval of the Charter Proposals, subject to the terms of the merger agreement. Notwithstanding the approval of the Charter Proposals, if the merger is not consummated for any reason, the actions contemplated by the Charter Proposals will not be effected.

Failure to vote by proxy or to vote online at the STPC Special Meeting, as well as an abstention from voting or a broker non-vote, will have the same effect as a vote “AGAINST” the Charter Proposals.

The Sponsor and STPC’s directors and officers have agreed to vote the Founder Shares and any shares of Class A Common Stock owned by them in favor of each of the Charter Proposals.

A copy of the Proposed Charter, as will be in effect assuming approval of each of the Charter Proposals and upon consummation of the merger and filing with the Secretary of State of the State of Delaware, is attached to this proxy statement/prospectus as Annex B.

Recommendation of the STPC Board of Directors

STPC’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE “FOR” EACH OF THE CHARTER PROPOSALS.

194

PROPOSAL NO. 6 — THE NYSE PROPOSAL

Immediately following consummation of the merger, STPC (and upon consummation of the merger, New Benson Hill) intends to effect the issuance and sale of 22.5 million shares of Class A Common Stock of STPC to the PIPE Investors pursuant to the PIPE Agreements.

Reasons for the Approval for Purposes of NYSE Rule 312.03

We are seeking stockholder approval in order to comply with Rule 312.03.

Under NYSE Listing Rule 312.03, a company is required to obtain stockholder approval prior to the issuance of common stock, or of securities convertible into or exercisable for common stock, if the number of shares of common stock to be issued is, or will be upon issuance, equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the common stock or of securities convertible into or exercisable for common stock.

Additionally, pursuant to NYSE Listing Rule 312.03, when a NYSE-listed company proposes to issue securities in connection with a business combination of the stock or assets of another company, stockholder approval is required if a substantial securityholder of such company has a 5% or greater interest, directly or indirectly, in such company or the assets to be acquired or in the consideration to be paid in the transaction or series of related transactions and the present or potential issuance of common stock could result in an increase in outstanding shares of common stock or voting power of 5% or more. NYSE Listing Rule 312.03(e) defines a substantial securityholder as the holder of an interest of 5% or more of either the number of shares of common stock or the voting power outstanding of a NYSE-listed company. Because Sponsor currently owns greater than 5% of STPC’s common shares, Sponsor is considered a substantial stockholder of STPC under NYSE Listing Rule 312.03(e).

Stockholder approval of the NYSE Proposal is also a condition to the closing under the merger agreement.

Vote Required for Approval

The approval of the NYSE Proposal requires the affirmative vote of a majority of the votes cast by holders of STPC common stock, voting together as a single class at a meeting at which quorum is present. Under Delaware law, a failure to vote proxy or to vote online at the STPC Special Meeting, as well as an abstention from voting or a broker non-vote, will have no effect on the NYSE Proposal. For purposes of NYSE rules, however, abstentions are treated as “votes cast” and will be counted as votes “AGAINST” this proposal.

The merger is conditioned upon the approval of the NYSE Proposal, subject to the terms of the merger agreement. Notwithstanding the approval of the NYSE Proposal, if the merger is not consummated for any reason, the actions contemplated by the NYSE Proposal will not be effected.

The Sponsor and STPC’s directors and officers have agreed to vote the Founder Shares and any shares of Class A Common Stock owned by them in favor of each of the NYSE Proposal.

Recommendation of the STPC Board of Directors

STPC’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE “FOR” THE NYSE PROPOSAL.

195

PROPOSAL NO. 7 — THE INCENTIVE PLAN PROPOSAL

Assuming the Business Combination Proposal, each of the Charter Proposals, and the NYSE Proposal are approved at the STPC Special Meeting, stockholders will be asked to approve the New Benson Hill 2021 Equity Incentive Plan (the “Incentive Plan”). The board of directors of STPC adopted the Incentive Plan on May 8, 2021, subject to its approval by the stockholders of STPC. If the stockholders approve the Incentive Plan, it will become effective upon the closing of the merger. The board of directors of STPC unanimously recommends that the stockholders vote “FOR” approval of the Incentive Plan.

Overview

Assuming the Business Combination Proposal, each of the Charter Proposals, and the NYSE Proposal are approved at the STPC Special Meeting, stockholders will be asked to approve the Incentive Plan. The board of directors of STPC adopted the Incentive Plan on May 8, 2021, subject to its approval by the stockholders of STPC. If the stockholders approve the Incentive Plan, it will become effective upon the closing of the merger. The board of directors of STPC unanimously recommends that the stockholders vote “FOR” approval of the Incentive Plan.

The Incentive Plan is described in more detail below. A copy of the Incentive Plan is attached to this proxy statement/prospectus as Annex I. If approved by STPC stockholders, and assuming that the Business Combination Proposal is approved, the Incentive Plan will become effective and will be administered by the New Benson Hill board of directors or by a committee that our board of directors designates for this purpose (referred to below as the plan administrator), which will have the authority to make awards under the Incentive Plan.

After careful consideration, the board of directors of STPC believes that approving the Incentive Plan is in the best interests of New Benson Hill. The Incentive Plan promotes ownership in New Benson Hill by its employees, nonemployee directors and consultants, and aligns incentives between these service providers and stockholders by permitting these service providers to receive compensation in the form of awards denominated in, or based on the value of, New Benson Hill Common Stock. Therefore, the board of directors of STPC recommends that the STPC stockholders approve the Incentive Plan.

Summary of the Incentive Plan

The following is a summary of the material features of the Incentive Plan. The summary is qualified in its entirety by reference to the complete text of the Incentive Plan attached as Annex I to this proxy statement/prospectus.

Purpose; Types of Awards

The purpose of the Incentive Plan is to attract, retain and appropriately reward employees, directors, and consultants in order to motivate their performance in the achievement of New Benson Hill’s business objectives and align their interests with the long-term interests of New Benson Hill’s stockholders. To accomplish this purpose, the Incentive Plan permits the granting of awards in the form of incentive stock options within the meaning of Section 422 of the Code, nonqualified stock options, stock appreciation rights (“SARs”), restricted stock, restricted stock units, performance based awards (including performance shares, performance units and performance bonus awards), and other stock-based or cash-based awards.

Shares Subject to the Incentive Plan

Subject to the assumptions set forth under “Basis of Presentation and Glossary” and assuming no public stockholders exercise their redemption rights, a total of          shares of New Benson Hill Common Stock will be reserved and available for issuance under the Incentive Plan, which includes (i)          shares of New Benson Hill Common Stock available for new issuances under the Incentive Plan, (ii)          shares of New Benson Hill Common Stock relating to the Exercise Price Options assumed by New Benson Hill in connection with the Business Combination and (iii)          shares of New Benson Hill Common Stock relating to the Earn Out Awards, with the total number of shares referred to in clauses (i) and (ii) representing 4% of the shares of New Benson Hill Common Stock outstanding as of

196

the Closing. The maximum number of shares that may be issued pursuant to options intended to be incentive stock options is        shares. Non-employee directors may only be granted and paid up to $       (when taken together with any fees paid to such non-employee director) in compensation per fiscal year.

The total number of shares of New Benson Hill Common Stock that will be reserved and may be issued under the Incentive Plan will automatically increase on the first trading day of each calendar year, beginning with calendar year 2022, by a number of shares equal to three percent (3%) of the total number of shares of New Benson Hill Common Stock outstanding on the last day of the prior calendar year. The plan administrator may act prior to January 1 of a given year to provide that there will be no increase in the share reserve for that year, or that the increase in the share reserve will be smaller than as provided in the Incentive Plan.

If an award granted under the Incentive Plan is forfeited, canceled, settled, or otherwise terminated without a distribution of shares, the shares underlying that award will again become available for issuance under the Incentive Plan. However, none of the following shares will be available for issuance under the Incentive Plan: (i) shares delivered to or withheld to pay withholding taxes or any applicable exercise price, and (ii) shares subject to any exercised stock-settled SAR or options. In addition, any shares tendered to exercise outstanding options or other awards or repurchased on the open market using exercise price proceeds will not be available for issuance under the Incentive Plan. Any substitute awards shall not reduce the shares authorized for grant under the Incentive Plan; provided, that for the avoidance of doubt, the Exercise Price Options shall not constitute substitute awards and shall be treated as awards granted under the Incentive Plan, including for purposes of the Incentive Plan's share reserve and the aforementioned share recycling features.

Administration of the Incentive Plan

The Incentive Plan will be administered by the plan administrator, who is the board of directors of New Benson Hill or a committee that the board of directors of New Benson Hill designates. The plan administrator has the power to determine the terms of the awards granted under the Incentive Plan, including the exercise price, the number of shares subject to each award, and the exercisability and vesting terms of the awards. The plan administrator also has the power to determine the persons to whom and the time or times at which awards will be made and to make all other determinations and take all other actions advisable for the administration of the Incentive Plan. All decisions made by the administrator pursuant to the provisions of the Incentive Plan will be final, conclusive and binding.

Participation

Participation in the Incentive Plan will be open to employees, non-employee directors, or consultants, who have been selected as an eligible recipient under the Incentive Plan by the plan administrator. Awards of incentive stock options, however, will be limited to employees of New Benson Hill or its affiliates. Following the consummation of the merger, it is expected that approximately 250 employees, 0 consultants and 8 of our non-employee directors will be eligible to participate in the Incentive Plan.

Types of Awards

The types of awards that may be made under the Incentive Plan are described below. All of the awards described below are subject to the conditions, limitations, restrictions, vesting and forfeiture provisions determined by the plan administrator, subject to the Incentive Plan.

Stock Options

The Incentive Plan provides for grants of both nonqualified and incentive stock options. A nonqualified stock option entitles the recipient to purchase shares of New Benson Hill Common Stock at a fixed exercise price. The exercise price per share will be determined by the compensation committee but such price will never be less than 100% of the fair market value of a share of common stock on the date of grant. Fair market value will generally be the closing price of a share of New Benson Hill Common Stock on NYSE on the date of grant. Nonqualified stock options under the Incentive Plan generally must be exercised within

197

ten years from the date of grant. A nonqualified stock option is an option that does not meet the qualifications of an incentive stock option as described below.

An incentive stock option is a stock option that meets the requirements of Section 422 of the Code. Incentive stock options may be granted only to employees and the aggregate fair market value of a share of New Benson Hill Common Stock determined at the time of grant with respect to incentive stock options that are exercisable for the first time by a participant during any calendar year may not exceed $100,000. No incentive stock option may be granted to any person who, at the time of the grant, owns or is deemed to own stock possessing more than 10% of New Benson Hill’s total combined voting power or that of any of New Benson Hill’s affiliates unless (i) the option exercise price is at least 110% of the fair market value of the stock subject to the option on the date of grant and (ii) the term of the incentive stock option does not exceed five years from the date of grant.

Unless otherwise determined by the plan administrator, each vested and outstanding option granted under the Incentive Plan will automatically be exercised on the last business day of the applicable option term, to the extent that, as of such date, (i) the exercise price of such option is less than the fair market value of a share, and (ii) the holder of such option remains actively in service.

Stock Appreciation Rights

A SAR entitles the holder to receive an amount equal to the difference between the fair market value of a share of New Benson Hill Common Stock on the exercise date and the exercise price of the SAR (which may not be less than 100% of the fair market value of a share of New Benson Hill Common Stock on the grant date), multiplied by the number of shares of New Benson Hill Common Stock subject to the SAR (as determined by the plan administrator). Unless otherwise determined by the plan administrator, each vested and outstanding SAR granted under the Incentive Plan will automatically be exercised on the last business day of the applicable SAR term, to the extent that, as of such date, (i) the exercise price of such SAR is less than the fair market value of a share, and (ii) the holder of such SAR remains actively in service.

Restricted Stock

A restricted stock award is an award of shares of New Benson Hill Common Stock that vest in accordance with the terms and conditions established by the plan administrator. The plan administrator will determine in the award agreement whether the participant will be entitled to receive dividends on such shares of restricted stock.

Restricted Stock Units

A restricted stock unit is a right to receive shares or the cash equivalent of New Benson Hill Common Stock at a specified date in the future, subject to forfeiture of such right. If the restricted stock unit has not been forfeited, then on the date specified in the restricted stock unit grant, New Benson Hill must deliver to the holder of the restricted stock unit unrestricted shares of New Benson Hill Common Stock (or, in the plan administrator’s sole discretion, cash equal to the shares that would otherwise be delivered, or partly in cash and partly in shares).

Other Stock-Based Awards

We may grant or sell to any participant a right or other interest that may be denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, shares of New Benson Hill Common Stock, including unrestricted Benson Hill Common Stock under the Incentive Plan or a dividend equivalent. A dividend equivalent is a right to receive payments, based on dividends with respect to shares of New Benson Hill Common Stock. To the extent that an award contains a right to receive dividends or dividend equivalents while the award remains unvested, the dividends and dividend equivalents will be accumulated and paid once and to the extent that the underlying award vests.

Other Cash-Based Awards

We may grant cash awards under the Incentive Plan, including cash awards as a bonus or upon the attainment of certain performance goals.

198

Performance-Based Awards

We may grant an award conditioned on satisfaction of certain performance criteria. Such performance-based awards include performance-based restricted shares and restricted stock units. Any dividends or dividend equivalents payable or credited to a participate with respect to any unvested performance-based award will be subject to the same performance goals as the shares or units underlying the performance-based award.

Performance Goals

If the plan administrator determines that an award under the Incentive Plan will be earned subject to the achievement of performance goals, the plan administrator may select one or more performance criteria upon which to grant such award, which may include, but are not limited to, any one or more of the following: earnings before interest and taxes; earnings before interest, taxes, depreciation and amortization; net operating profit after tax; cash flow; revenue; net revenues; sales; days sales outstanding; income; net income; operating income; net operating income, operating margin; earnings; earnings per share; return on equity; return on investment; return on capital; return on assets; return on net assets; total stockholder return; economic profit; market share; appreciation in the fair market value, book value or other measure of value of a share of common stock; expense/cost control; working capital; customer satisfaction; employee retention or employee turnover; employee satisfaction or engagement; environmental, health, or other safety goals; individual performance; strategic objective milestones; any other criteria specified by the plan administrator in its sole discretion; or, as applicable, any combination of, or a specified increase or decrease in, any of the foregoing.

Equitable Adjustments

In the event of a merger, consolidation, reclassification, recapitalization, spin-off, spin-out, repurchase or other reorganization or corporate transaction or event, extraordinary dividend, stock split or reverse stock split, combination or exchange of shares, or other change in corporate structure or payment of any other distribution, the maximum number and kind of shares of New Benson Hill Common Stock reserved for issuance or with respect to which awards may be granted under the Incentive Plan will be adjusted to reflect such event, and the plan administrator will make such adjustments as it deems appropriate and equitable in the number, kind and exercise price of New Benson Hill Common Stock covered by outstanding awards made under the Incentive Plan, and in any other matters that relate to awards and that are affected by the changes in the shares referred to in this section.

Change in Control

In the event of any proposed change in control (as defined in the Incentive Plan), the plan administrator will take any action as it deems appropriate and equitable to effectuate the purposes of the Incentive Plan and to protect the participants who hold outstanding awards under the Incentive Plan, which action may include, without limitation, the following: (i) the continuation of any award, if New Benson Hill is the surviving corporation; (ii) the assumption of any award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any award, provided, however, that any such substitution with respect to options and SARs shall occur in accordance with the requirements of Section 409A of the Code; or (iv) settlement of any award for the change in control price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the change in control price or if the plan administrator determines that the award cannot reasonably become vested pursuant to its terms, such award shall terminate and be canceled without consideration.

Amendment and Termination

The plan administrator may alter, amend, modify, or terminate the Incentive Plan at any time, provided that the approval of our stockholders will be obtained for any amendment to the Incentive Plan that requires stockholder approval under the rules of the stock exchange(s) on which the New Benson Hill Common Stock is then listed or in accordance with other applicable law, including, but not limited to, an increase in the number of shares of New Benson Hill Common Stock reserved for issuance, a reduction in the exercise

199

price of options or other entitlements, an extension of the maximum term of any award, or an amendment that grants the plan administrator additional powers to amend the Incentive Plan. In addition, no modification of an award will, without the prior written consent of the participant, adversely alter or impair any rights or obligations under any award already granted under the Incentive Plan, unless the plan administrator expressly reserved the right to do so at the time of the award.

Material U.S. Federal Income Tax Effects

The following discussion of certain relevant United States federal income tax effects applicable to certain awards granted under the Incentive Plan is only a summary of certain of the United States federal income tax consequences applicable to United States residents under the Incentive Plan, and reference is made to the Code for a complete statement of all relevant federal tax provisions. No consideration has been given to the effects of foreign, state, local and other laws (tax or other) on the Incentive Plan or on a participant, which laws will vary depending upon the particular jurisdiction or jurisdictions involved. In particular, participants who are stationed outside the United States may be subject to foreign taxes as a result of the Incentive Plan.

Nonqualified Stock Options

An optionee subject to United States federal income tax will generally not recognize taxable income for United States federal income tax purposes upon the grant of a nonqualified stock option. Rather, at the time of exercise of the nonqualified stock option, the optionee will recognize ordinary income, subject to wage and employment tax withholding, and New Benson Hill will be entitled to a deduction, in an amount equal to the excess of the fair market value of the shares on the date of exercise over the exercise price. If the shares acquired upon the exercise of a nonqualified stock option are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of such shares on the date of such exercise will generally be taxable as long-term or short-term capital gain or loss (if the shares are a capital asset of the optionee), depending upon the length of time such shares were held by the optionee.

Incentive Stock Options

An optionee subject to United States federal income tax will generally not recognize taxable income for United States federal income tax purposes upon the grant of an incentive stock option (within the meaning of Section 422 of the Code) and New Benson Hill will not be entitled to a deduction at that time. If the incentive stock option is exercised during employment or within 90 days following the termination thereof (or within one year following termination, in the case of a termination of employment due to death or disability, as such terms are defined in the Incentive Plan), the optionee will not recognize any income and New Benson Hill will not be entitled to a deduction. The excess of the fair market value of the shares on the exercise date over the exercise price, however, is includible in computing the optionee’s alternative minimum taxable income. Generally, if an optionee disposes of shares acquired by exercising an incentive stock option either within two years after the date of grant or one year after the date of exercise, the optionee will recognize ordinary income, and New Benson Hill will be entitled to a deduction, in an amount equal to the excess of the fair market value of the shares on the date of exercise (or the sale price, if lower) over the exercise price. The balance of any gain or loss will generally be treated as a capital gain or loss to the optionee. If the shares are disposed of after the two-year and one-year periods described above, New Benson Hill will not be entitled to any deduction, and the entire gain or loss for the optionee will be treated as a capital gain or loss.

SARs

A participant subject to United States federal income tax who is granted a SAR will not recognize ordinary income for United States federal income tax purposes upon receipt of the SAR. At the time of exercise, however, the participant will recognize ordinary income, subject to wage and employment tax withholding, equal to the value of any cash received and the fair market value on the date of exercise of any shares received. New Benson Hill will not be entitled to a deduction upon the grant of a SAR, but generally will be entitled to a deduction for the amount of income the participant recognizes upon the participant’s

200

exercise of the SAR. The participant’s tax basis in any shares received will be the fair market value on the date of exercise and, if the shares are later sold or exchanged, then the difference between the amount received upon such sale or exchange and the fair market value of the shares on the date of exercise will generally be taxable as long-term or short-term capital gain or loss (if the stock is a capital asset of the participant) depending upon the length of time such shares were held by the participant.

Restricted Stock

A participant subject to United States federal income tax generally will not be taxed upon the grant of a restricted stock award, but rather will recognize ordinary income for United States federal income tax purposes in an amount equal to the fair market value of the shares at the time the restricted stock is no longer subject to a substantial risk of forfeiture (within the meaning of the Code). New Benson Hill generally will be entitled to a deduction at the time when, and in the amount that, the participant recognizes ordinary income on account of the lapse of the restrictions. A participant’s tax basis in the shares will equal the fair market value of those shares at the time the restrictions lapse, and the participant’s holding period for capital gains purposes will begin at that time. Any cash dividends paid on the shares before the restrictions lapse will be taxable to the participant as additional compensation (and not as dividend income). Under Section 83(b) of the Code, a participant may elect to recognize ordinary income at the time the restricted shares are awarded in an amount equal to their fair market value at that time, notwithstanding the fact that such shares are subject to restrictions and a substantial risk of forfeiture. If such an election is made, no additional taxable income will be recognized by such participant at the time the restrictions lapse, the participant will have a tax basis in the restricted shares equal to their fair market value on the date of their award, and the participant’s holding period for capital gains purposes will begin at that time. New Benson Hill generally will be entitled to a tax deduction at the time when, and to the extent that, ordinary income is recognized by such participant.

Restricted Stock Units

A participant subject to United States federal income tax who is granted a restricted stock unit will not recognize ordinary income for United States federal income tax purposes upon the receipt of the restricted stock unit, but rather will recognize ordinary income in an amount equal to the fair market value of the shares at the time the award is settled into shares, subject to wage and employment tax withholding, and New Benson Hill will have a corresponding deduction at that time.

Other Stock-Based and Other Cash-Based Awards

In the case of other stock-based and other cash-based awards, depending on the form of the award, a participant subject to United States federal income tax will not be taxed upon the grant of such an award, but, rather, will recognize ordinary income for United States federal income tax purposes when such an award vests or otherwise is free of restrictions. In any event, New Benson Hill will be entitled to a deduction at the time when, and in the amount that, a participant recognizes ordinary income.

In addition to the tax impact to New Benson Hill described above, New Benson Hill’s deduction may also be limited by Section 280G or Section 162(m) of the Code. In general, Section 162(m) of the Code denies a publicly held corporation a deduction for United States federal income tax purposes for compensation in excess of $1,000,000 per year per covered employee.

New Plan Benefits

As of the date hereof, no awards have been granted under the Incentive Plan. As explained in more detail below, the aggregate number of shares and aggregate total dollar value of potential future awards under the Incentive Plan that may be made to any of our named executive officers or to our executive officers, non-executive officer employees or non-executive directors as a group are not yet determinable.

If the merger and Incentive Plan are approved, as previously disclosed, holders of Benson Hill Options to purchase capital stock of Benson Hill under the SIP outstanding immediately prior to the consummation

201

of the merger will be converted into New Benson Hill Options to purchase New Benson Hill Common Stock. Any Benson Hill Options converted into New Benson Hill Options will be subject to terms and conditions consistent with the SIP, provided that the exact number of New Benson Hill Options into which the Benson Hill Options convert is not currently known. 12,592,781 Benson Hill Options were outstanding as of the date of the merger agreement. In addition, the shares of New Benson Hill Common Stock underlying the Net New Benson Hill Options are reflected in the 130,000,000 shares being registered in connection with this Form S-4. The shares of New Benson Hill Common Stock underlying the Exercise Price Options will be granted as awards under the Incentive Plan and are reflected in the Incentive Plan's share reserve that will be registered on a Form S-8 as soon as reasonably practicable after New Benson Hill becomes eligible to use such form. The Exercise Price Options represent a portion of the New Benson Hill Options to purchase shares, the number of which is determined at Closing and is equal to the Aggregate Exercise Price (as such term is defined in the Merger Agreement appended hereto as Annex A) divided by $10.00. Any Exercise Price Options that are vested as of Closing, or would vest between Closing and the date New Benson Hill files the Form S-8 registering the Incentive Plan's share reserve, will be subject to a restriction preventing the exercise of such option until New Benson Hill files such Form S-8. The exact number of Exercise Price Options is not currently known and will not be determinable until Closing since holders of Benson Hill Options may still exercise vested options and forfeit unvested options prior to Closing, which actions would reduce the Aggregate Exercise Price. If the Closing had occurred on June 30, 2021, the estimated number of shares of New Benson Hill Common Stock underlying the Exercise Price Options would have been 2,245,720.

In addition, if the merger and Incentive Plan are approved, as previously disclosed, a pool of up to 2,037,320 shares of New Benson Hill Common Stock will be set aside to provide grants of incentive equity awards under the Incentive Plan to certain holders of Benson Hill Options (referred to elsewhere herein as the Earn Out Awards). The number of Earn Out Awards may be adjusted prior to the consummation of the transactions as described in the merger agreement and elsewhere in this proxy statement/prospectus.

The aggregate number of shares and aggregate total dollar value of the New Benson Hill Options and Earn Out Awards is not determinable because the total shares attributable to New Benson Hill Options and Earn Out Awards under the merger agreement represent a share pool that will be distributed pro-rata as contemplated by the merger agreement following the closing. Thus, forfeitures and exercises of options to purchase capital stock of Benson Hill between the date of the merger agreement and the closing of the transactions contemplated thereby will impact that final number of shares and total dollar value received by future New Benson Hill Option and Earn Out Award recipients. In addition, the dollar value of any of potential future award granted under the Incentive Plan will depend on a number of factors, including the fair market value of New Benson Hill Common Stock on future dates, the exercise decisions made by the participants, and the extent to which any applicable performance goals necessary for vesting or payment are achieved.

Registration with the SEC

If the Incentive Plan is approved by our stockholders and becomes effective, New Benson Hill is expected to file a registration statement on Form S-8 registering the shares reserved for issuance under the Incentive Plan as soon as reasonably practicable after becoming eligible to use such form.

Equity Compensation Plan Information

STPC did not maintain, or have any securities authorized for issuance under, any equity compensation plans as of December 31, 2020.

Vote Required for Approval

Approval of the Incentive Plan Proposal require the affirmative vote of a majority of the votes cast by holders of STPC common stock, voting together as a single class at a meeting at which a quorum is present. Under Delaware law, a failure to vote proxy or to vote online at the STPC Special Meeting, as well as an abstention from voting or a broker non-vote, will have no effect on the Incentive Plan Proposal. For purposes of NYSE rules, however, abstentions are treated as “votes cast” and will be counted as votes “AGAINST” this proposal.

202

The Sponsor and STPC’s directors and officers have agreed to vote the Founder Shares and any shares of Class A Common Stock owned by them in favor of each of the Incentive Plan Proposal.

A copy of the Incentive Plan is attached to this proxy statement/prospectus as Annex I.

Recommendation of the STPC Board of Directors

STPC’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE “FOR” THE INCENTIVE PLAN PROPOSAL.

203

PROPOSAL NO. 8 — THE ADJOURNMENT PROPOSAL

The Adjournment Proposal, if adopted, will allow STPC’s board of directors to adjourn the STPC Special Meeting to a later date or dates, if necessary, to permit further solicitation of proxies if, based upon the tabulated vote at the time of the STPC Special Meeting, there are not sufficient votes to approve the Business Combination Proposal, the Charter Proposals, the NYSE Proposal or the Incentive Plan Proposal, or holders of STPC Class A Common Stock have elected to redeem an amount of Class A Common Stock such that STPC would have less than $5,000,001 of net tangible assets or the Minimum Cash Condition would not be satisfied or waived by Benson Hill. In no event will STPC’s board of directors adjourn the STPC Special Meeting or consummate the merger beyond the date by which it may properly do so under its Existing Charter and Delaware law.

Consequences if the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by STPC’s stockholders, STPC’s board of directors may not be able to adjourn the STPC Special Meeting to a later date in the event that there are insufficient votes for the approval of the Business Combination Proposal, the Charter Proposals, the NYSE Proposal or the Incentive Plan Proposal, or holders of STPC’s Class A Common Stock have elected to redeem an amount of Class A Common Stock such that STPC would have less than $5,000,001 of net tangible assets or the Minimum Condition would not be satisfied or waived by Benson Hill, and may be unable to consummate the merger. If STPC does not consummate the merger and fails to complete an initial business combination by January 8, 2023 (subject to the requirements of law), it will be required to dissolve and liquidate its Trust Account by returning the then remaining funds in such account to the public stockholders.

Vote Required for Approval

The approval of the Adjournment Proposal requires affirmative vote of a majority of the votes cast by holders of STPC common stock, voting together as a single class, regardless of whether a quorum is present.

Failure to vote by proxy or to vote online at the STPC Special Meeting, as well as an abstention from voting or a broker non-vote, will have no effect on the Adjournment Proposal.

The merger is not conditioned upon the approval of the Adjournment Proposal.

The Sponsor and STPC’s directors and officers have agreed to vote the Founder Shares and any shares of Class A Common Stock owned by them in favor of each of the Adjournment Proposal.

Recommendation of the STPC Board of Directors

STPC’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE “FOR” THE APPROVAL OF THE ADJOURNMENT PROPOSAL.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES

The following discussion is a summary of the material U.S. federal income tax consequences of (i) the merger to U.S. Holders of Exisiting Benson Hill Common Stock, (ii) the ownership and disposition of New Benson Hill Common Stock (including Earn Out Shares) received in the merger and (iii) the exercise by beneficial owners of Class A Common Stock (“STPC public shares”) of their redemption rights in connection with the merger. This discussion does not address any tax consequences arising under the laws of any state, local or non-U.S. jurisdiction, or under any U.S. federal laws other than those pertaining to the income tax. This discussion applies only to beneficial owners of STPC public shares and beneficial owners of Existing Benson Hill Common Stock that hold such STPC public shares or Existing Benson Hill Common Stock, respectively, as a capital asset for U.S. federal income tax purposes (generally property held for investment).

This discussion is based on the provisions of the Code, U.S. Treasury regulations, administrative rulings and judicial decisions, all as of the date hereof, and all of which are subject to change, possibly with retroactive effect. We cannot assure you that a change in law (including, but not limited to, proposed legislation) will not significantly alter the tax considerations that we describe in this summary. We have not sought any ruling from the IRS with respect to the statements made and the conclusions reached in the following summary, and there can be no assurance that the IRS or a court will agree with such statements and conclusions.

This summary does not address the Medicare tax on certain investment income, the alternative minimum tax, U.S. federal estate or gift tax laws, any state, local or any non-U.S. tax laws. In addition, this discussion does not address all U.S. federal income tax considerations that may be important to a particular holder in light of the holder’s circumstances, or to certain categories of investors that may be subject to special rules, such as:

•

holders of our Founder Shares or Private Placement Warrants;

•

holders of options and warrants to purchase Existing Benson Hill Common Stock;

•

holders of Benson Hill Preferred Stock;

•

banks or other financial institutions;

•

tax-exempt entities;

•

insurance companies;

•

dealers in securities or foreign currencies;

•

traders in securities subject to a mark-to-market method of accounting for U.S. federal income tax purposes with respect to the STPC public shares;

•

partnerships or other pass-through entities for U.S. federal income tax purposes or holders of interests therein;

•

regulated investment companies, mutual funds or real estate investment trusts;

•

“controlled foreign corporations” or “passive foreign investment companies”;

•

persons that acquired our STPC public shares through the exercise of employee stock options or otherwise as compensation or through a tax-qualified retirement plan;

•

U.S. Holders whose functional currency is not the U.S. dollar;

•

former citizens or residents of the United States;

•

holders of Existing Benson Hill Common Stock or Benson Hill Preferred Stock for which the holder (a “Dissenting Stockholder”) thereof (i) has not voted in favor of the merger or consented to it in writing and (ii) has demanded the appraisal of such shares in accordance with, and has complied in all respects with, Section 262 of the DGCL;

•

persons that hold our STPC public shares as part of a straddle, hedge, integrated transaction or similar transaction; or

205

•

persons who own five percent or more (by vote or value) of our STPC public shares or Existing Benson Hill Common Stock.

For purposes of this discussion, a “U.S. Holder” is a beneficial owner of STPC public shares or Existing Benson Hill Common Stock, that is, for U.S. federal income tax purposes:

•

an individual who is a citizen or resident of the United States;

•

a corporation or other entity treated as a corporation and organized in or under the laws of the United States, any state thereof or the District of Columbia;

•

an estate the income of which is includible in gross income for U.S. federal income tax purposes regardless of its source; or

•

a trust (A) the administration of which is subject to the primary supervision of a U.S. court and which has one or more United States persons who have the authority to control all substantial decisions of the trust or (B) that has made a valid election under applicable U.S. Treasury regulations to be treated as a United States person.

A “Non U.S. Holder” is a beneficial owner of STPC public shares or Existing Benson Hill Common Stock who is or that is, for U.S. federal income tax purposes, an individual, corporation, estate or trust that is not a U.S. Holder.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes or other pass-through entity holds STPC public shares, Existing Benson Hill Common Stock or New Benson Hill Common Stock, the U.S. federal income tax treatment of a partner in the partnership or equityholder in the pass-through entity generally will depend upon the status of the partner or equityholder, upon the activities of the partnership or other pass-through entity and upon certain determinations made at the partner or equityholder level. Accordingly, we urge partners in entities or arrangements treated as partnerships for U.S. federal income tax purposes and equityholders in such other pass-through entities holding STPC public shares, Existing Benson Hill Common Stock or New Benson Hill Common Stock, to consult their tax advisors regarding the U.S. federal income tax considerations of the exercise by such partnerships or other pass-through entities of their redemption rights in connection with the merger.

The tax consequences to you of the merger with respect to your Existing Benson Hill Common Stock, the ownership and disposition of New Benson Hill Common Stock recived in the merger, or of a redemption of your STPC public shares, as applicable, will depend on your specific situation. You should consult with your own tax advisor as to the tax consequences, in your particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign or other tax laws and of changes in those laws.

Tax Consequences to U.S. Holders

The following discussion is a summary of certain material U.S. federal income tax consequences of the merger and the ownership and disposition of New Benson Hill Common Stock to U.S. Holders who receive such New Benson Hill Common Stock pursuant to the merger. The discussion also addresses the U.S. federal income tax consequences of redemptions of STPC public shares by U.S. Holders of STPC public shares. We have not requested, and do not intend to request, a ruling from the IRS as to the U.S. federal income tax consequences of the merger or of the redemption of STPC public shares. Consequently, no assurance can be given that the IRS will not assert, or that a court would not sustain, a position contrary to any of those set forth below. Each holder of STPC public shares or Existing Benson Hill Common Stock is urged to consult its tax advisor with respect to the particular tax consequence of the merger or a redemption to such holder.

Tax Consequences of the Merger to U.S. Holders of Existing Benson Hill Common Stock

It is the opinion of Kirkland & Ellis LLP that the merger should qualify as a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code. This opinion is based on facts and representations contained in representation letters provided by Benson Hill, STPC and Merger Sub and on customary factual assumptions, and further assumes that any consideration paid in respect of

206

dissenting shares to Dissenting Stockholders will not exceed 10% of the total value of all consideration paid to holders of Existing Benson Hill Common Stock and Benson Hill Preferred Stock and the merger is completed in the manner set forth in the merger agreement and the Registration Statement on Form S-4 of which this proxy statement/prospectus forms a part. If any assumption or representation is or becomes inaccurate, the U.S. federal income tax consequences of the merger could be adversely affected. In addition, neither the obligation of STPC nor the obligation of Benson Hill to complete the merger is conditioned upon the receipt of an opinion from counsel confirming whether the merger will so qualify.

Subject to the qualifications and limitations set forth herein, if the merger qualifies as a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code, U.S. Holders of Existing Benson Hill Common Stock will generally not recognize any gain or loss as a result of the merger. Pursuant to the merger, U.S. Holders of Existing Benson Hill Common Stock will receive shares of New Benson Hill Common Stock (including any Earn Out Shares held in the escrow attributable to each U.S. Holder’s Existing Benson Hill Common Stock) in exchange for their shares of Existing Benson Hill Common Stock. Each U.S. Holder’s tax basis in the shares of New Benson Hill Common Stock received in the merger will be the same as its tax basis in the shares of Existing Benson Hill Common Stock surrendered in the merger in exchange therefor. The holding period of the shares of New Benson Hill Common Stock received in the merger by the U.S. Holder will include the holding period of the shares of Existing Benson Hill Common Stock surrendered in the merger in exchange therefor.

All U.S. Holders of Existing Benson Hill Common Stock are urged to consult their tax advisors as to the tax consequences to them of the merger under such holder’s particular circumstances.

Distributions on New Benson Hill Common Stock

The gross amount of any distribution that is made out of New Benson Hill’s current and accumulated earnings and profits (as determined for U.S. federal income tax purposes) will generally be taxable to a U.S. Holder as ordinary dividend income on the date such distribution is actually or constructively received by such U.S. Holder. Any such dividends paid to corporate U.S. Holders of New Benson Hill Common Stock generally will qualify for the dividends received deduction if the requisite holding period is satisfied. Dividends paid to a non-corporate U.S. Holder generally will constitute “qualified dividends” that will be subject to tax at the maximum tax rate accorded to long-term capital gains.

Non-corporate U.S. Holders that do not meet a minimum holding period requirement or that elect to treat the dividend income as “investment income” pursuant to Section 163(d)(4) of the Code (dealing with the deduction for investment interest expense) will not be eligible for the reduced rates of taxation applicable to qualified dividends. In addition, the rate reduction will not apply to dividends if the recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has been met.

To the extent that the amount of any distribution made by New Benson Hill on the New Benson Hill Common Stock exceeds New Benson Hill’s current and accumulated earnings and profits for a taxable year (as determined under U.S. federal income tax principles), the distribution will first be treated as a tax-free return of capital, causing a reduction (but not below zero) in the adjusted basis of the U.S. Holder’s New Benson Hill Common Stock, and to the extent the amount of the distribution exceeds the U.S. Holder’s tax basis, the excess will be taxed as capital gain recognized on a sale or exchange as described below under “— Sale, Exchange, Redemption or Other Taxable Disposition of New Benson Hill Common Stock.”

Sale, Exchange, Redemption or Other Taxable Disposition of New Benson Hill Common Stock

A U.S. Holder will generally recognize gain or loss on any sale, exchange, redemption, or other taxable disposition of New Benson Hill Common Stock in an amount equal to the difference between the amount realized on the disposition and such U.S. Holder’s adjusted tax basis in such New Benson Hill Common Stock. Any gain or loss recognized by a U.S. Holder on a taxable disposition of New Benson Hill Common Stock will generally be capital gain or loss and will be long-term capital gain or loss if the holder’s holding period in the New Benson Hill Common Stock exceeds one year at the time of the disposition. Preferential tax rates may apply to long-term capital gains recognized by non-corporate U.S. Holders (including

207

individuals). The deductibility of capital losses is subject to limitations. Any gain or loss recognized by a U.S. Holder on the sale or exchange of New Benson Hill Common Stock will generally be treated as U.S. source gain or loss.

Tax Consequences for U.S. Holders of Earn Out Shares

Although there is no authority directly on point with respect to a transaction involving the same facts, each U.S. Holder of Existing Benson Hill Common Stock should generally be treated as the owner, for U.S. federal income tax purposes, of any Earn Out Shares held in escrow that are attributable to such holder’s Existing Benson Hill Common Stock at the time of the merger, and the vesting of such Earn Out Shares upon the achievement of certain earn-out thresholds is not expected to be treated as a taxable event. The tax treatment of any cancellation of Earn Out Shares upon a failure to meet the earn-out thresholds is unclear. Any such forfeiture may be treated as a tax-free adjustment to the amount of consideration originally received by such U.S. Holder in the merger. Alternatively, it could also be treated as a taxable disposition of Earn Out Shares, with gain or loss recognized as described above under “— Sale, Exchange, Redemption or Other Taxable Disposition of New Benson Hill Common Stock.”

U.S. Holders of Existing Benson Hill Common Stock should consult their tax advisors as to the tax consequences to them of the receipt or forfeiture of the Earn Out Shares under such holder’s particular circumstances.

Tax Consequences for U.S. Holders of STPC Public Shares

The discussion below applies to U.S. Holders of STPC public shares that exercise the redemption rights described above under “STPC Special Meeting of Stockholders — Redemption Rights” with respect to their STPC public shares.

Treatment of Redemption of STPC Public Shares

The treatment of a redemption of STPC public shares for U.S. federal income tax purposes will depend on whether the redemption qualifies as a sale of the STPC public shares under Section 302 of the Code. If the redemption qualifies as a sale of the STPC public shares, U.S. Holders will recognize gain or loss as described below under “— Gain or Loss on Redemptions Treated as a Sale of STPC Public Shares.” If the redemption does not qualify as a sale of STPC public shares, U.S. Holders will be treated as receiving a corporate distribution subject to tax as described below under “— Taxation of Redemptions Treated as Distributions on STPC Public Shares.” Whether a redemption qualifies for sale treatment will depend largely on the total number of shares of STPC public shares treated as held (including any shares constructively owned by U.S. Holders, including STPC public shares constructively held as a result of owning any STPC publicly traded warrants) relative to all of the STPC public shares outstanding both before and after the redemption. The redemption of STPC public shares generally will be treated as a sale of the STPC public shares (rather than as a corporate distribution) if the redemption (i) results in a “complete termination” of the U.S. Holder’s interest in STPC, (ii) is “not essentially equivalent to a dividend” with respect to the U.S. Holder or (iii) is a “substantially disproportionate redemption” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, U.S. Holders must take into account not only STPC public shares actually owned by them, but also STPC public shares that are constructively owned by them. U.S. Holders may constructively own, in addition to shares owned directly, shares owned by certain related individuals and entities in which they have an interest or that have an interest in them, as well as any shares they have a right to acquire by exercise of an option (such as STPC publicly traded warrants). There will be a complete termination of their interest if either (i) all of the shares of STPC public shares actually and constructively owned by U.S. Holders are redeemed or (ii) all of the STPC public shares actually owned by U.S. Holders are redeemed and they are eligible to waive, and do waive, the attribution of shares owned by certain family members and they do not constructively own any other shares. The redemption of STPC public shares will not be essentially equivalent to a dividend if a U.S. Holder’s redemption results in a “meaningful reduction” of their proportionate interest in STPC. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in STPC will depend on the particular facts and circumstances. However, the IRS has indicated in a published ruling that

208

even a small reduction in the proportionate interest of a small minority stockholder in a publicly held corporation who exercises no control over its corporate affairs may constitute such a “meaningful reduction.” In order to meet the “substantially disproportionate” test, the percentage of outstanding STPC public shares actually and constructively owned by a U.S. Holder immediately following the redemption of the STPC public shares must, among other requirements, be less than 80% of the percentage of the outstanding STPC public shares actually and constructively owned by a U.S. Holder immediately before the redemption. U.S. Holders are urged to consult with their tax advisors as to the tax consequences of a redemption.

If none of the foregoing tests are satisfied, then the redemption proceeds will be treated as a corporate distribution and the tax effects will be as described under “— Taxation of Redemptions Treated as Distributions on STPC Public Shares,” below. After the application of those rules, any remaining tax basis U.S. Holders have in the redeemed STPC public shares will be added to their adjusted tax basis in their remaining STPC public shares, or, if they have none, to their adjusted tax basis in STPC publicly traded warrants held by them or possibly in other shares constructively owned by them.

Taxation of Redemptions Treated as Distributions on STPC Public Shares

If the redemption of U.S. Holders’ STPC public shares does not qualify as a sale of STPC public shares, such holders will be treated as receiving a distribution from STPC. U.S. Holders generally will be required to include in gross income as dividends the amount of proceeds received in connection with such a redemption to the extent the distribution is paid out of STPC’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). Distributions in excess of such earnings and profits generally will treated as a return of capital that will be applied against and reduce U.S. Holders’ basis in their shares (but not below zero), with any remaining excess treated as gain from the sale or exchange of such shares as described below under “— Gain or Loss on Redemptions Treated as a Sale of STPC Public Shares.”

If a U.S. Holders is a corporate U.S. Holder, dividends paid by STPC generally would be eligible for the dividends received deduction allowed to domestic corporations in respect of dividends received from other domestic corporations so long as the U.S. Holder satisfies the holding period requirement for the dividends received deduction. If a U.S. Holder is a non-corporate U.S. Holder, under tax laws currently in effect, dividends generally will be taxed at the lower applicable long-term capital gains rate so long as the U.S. Holder satisfies the holding period requirement of at least sixty (60) days which begins within a certain number of days before the ex-dividend date and certain other requirements are met. It is unclear, however, whether the redemption rights with respect to STPC public shares may prevent U.S. Holders from satisfying the applicable holding period requirements with respect to the dividends received deduction or the preferential tax rate for qualified dividend income, as the case may be. U.S. Holders should consult with their own tax advisor regarding the availability of the dividends received deduction or the lower preferential rate for qualified dividend income, as the case may be, for any amounts treated as dividends with respect any redemption of STPC public shares.

Gain or Loss on Redemptions Treated as a Sale or Exchange of STPC Public Shares

If a redemption of a U.S. Holder’s STPC public shares qualifies as a sale of STPC public shares, it generally will recognize capital gain or loss in an amount equal to the difference between (i) the amount of cash received in the redemption and (ii) its adjusted tax basis in the STPC public shares so redeemed.

Any such capital gain or loss generally will be long-term capital gain or loss if a U.S. Holder’s holding period for the STPC public shares so disposed of exceeds one (1) year. Long-term capital gains recognized by non-corporate U.S. Holders generally will be eligible for taxation at reduced rates. The deductibility of capital losses is subject to limitations.

Information Reporting with Respect to the Redemption for Significant Holders

Certain information reporting requirements may apply to each U.S. Holder that is a “significant holder” of STPC public shares. A “significant holder” is a beneficial owner of STPC public shares that, immediately prior to the redemption, actually or constructively owns 5% or more of the outstanding STPC

209

public shares (by vote or value). U.S. Holders are urged to consult with their tax advisors as to the potential application of these reporting requirements.

Tax Consequences to Non-U.S. Holders

The following discussion is a summary of certain material U.S. federal income tax consequences of the merger and the ownership and disposition of New Benson Hill Common Stock to Non-U.S. Holders who receive such New Benson Hill Common Stock pursuant to the merger. The discussion also addresses the U.S. federal income tax consequences of redemptions of STPC public shares by Non-U.S. Holders of STPC public shares.

U.S. Federal Income Tax Consequences of the Merger to Non-U.S. Holders of Existing Benson Hill Common Stock

As described above under “ — Tax Consequences to U.S. Holders — Tax Consequences of the Merger to U.S. Holders of Existing Benson Hill Common Stock”, it is the opinion of Kirkland & Ellis LLP that the merger should qualify as a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code. Subject to the qualifications and limitations set forth herein, if the merger qualifies as a “reorganization” for U.S. federal income tax purposes within the meaning of Section 368(a) of the Code, Non-U.S. Holders of Existing Benson Hill Common Stock will generally not recognize any gain or loss as a result of the merger. Pursuant to the merger, Non-U.S. Holders of Existing Benson Hill Common Stock will receive shares of New Benson Hill Common Stock (including any Earn Out Shares held in the escrow attributable to each Non-U.S. Holder’s Existing Benson Hill Common Stock) in exchange for their shares of Existing Benson Hill Common Stock. Each Non-U.S. Holder’s tax basis in the shares of New Benson Hill Common Stock received in the merger will be the same as its tax basis in the shares of Existing Benson Hill Common Stock surrendered in the merger in exchange therefor. The holding period of the shares of New Benson Hill Common Stock received in the merger by the Non-U.S. Holder will include the holding period of the shares of Existing Benson Hill Common Stock surrendered in the merger in exchange therefor.

All Non-U.S. Holders of Existing Benson Hill Common Stock are urged to consult their tax advisors as to the tax consequences to them of the merger under such holder’s particular circumstances.

Distributions on New Benson Hill Common Stock

Distributions of cash or property (including a constructive distribution) to a Non-U.S. Holder in respect of New Benson Hill Common Stock will generally constitute dividends for U.S. federal income tax purposes to the extent paid from New Benson Hill’s current or accumulated earnings and profits, as determined under U.S. federal income tax principles. If a distribution exceeds New Benson Hill’s current and accumulated earnings and profits, the excess will generally be treated first as a tax-free return of capital to the extent of the Non-U.S. Holder’s adjusted tax basis in the New Benson Hill Common Stock. Any remaining excess will be treated as capital gain and will be treated as described below under “— Sale, Exchange, Redemption or Other Taxable Disposition of New Benson Hill Common Stock.”

Dividends paid to a Non-U.S. Holder of New Benson Hill Common Stock generally will be subject to withholding of U.S. federal income tax at a 30% rate, unless such Non-U.S. Holder is eligible for a reduced rate of withholding tax under an applicable income tax treaty and provides proper certification of its eligibility for such reduced rate as described below. However, dividends that are effectively connected with the conduct of a trade or business by the Non-U.S. Holder within the United States (and, if required by an applicable income tax treaty, are attributable to a U.S. permanent establishment or fixed base of the Non-U.S. Holder) are not subject to such withholding tax, provided certain certification and disclosure requirements are satisfied (generally by providing an IRS Form W-8ECI). Instead, such dividends are subject to United States federal income tax on a net income basis in the same manner as if the Non-U.S. Holder were a United States person as defined under the Code. Any such effectively connected dividends received by a foreign corporation may be subject to an additional “branch profits tax” at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

210

A Non-U.S. Holder of New Benson Hill Common Stock who wishes to claim the benefit of an applicable treaty rate and avoid backup withholding, as discussed below, for dividends will be required (a) to complete the applicable IRS Form W-8 and certify under penalty of perjury that such holder is not a United States person as defined under the Code and is eligible for treaty benefits or (b) if the shares of New Benson Hill Common Stock are held through certain foreign intermediaries, to satisfy the relevant certification requirements of applicable U.S. Treasury regulations. Special certification and other requirements apply to certain Non-U.S. Holders that are pass-through entities rather than corporations or individuals.

A Non-U.S. Holder of New Benson Hill Common Stock eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders are urged to consult their tax advisors regarding their entitlement to the benefits under any applicable income tax treaty.

Sale, Exchange, Redemption or Other Taxable Disposition of New Benson Hill Common Stock

Subject to the discussion of backup withholding and FATCA below, Non-U.S. Holders generally will not be subject to U.S. federal income tax on any gain realized on the taxable disposition of New Benson Hill Common Stock unless:

•

such gain is effectively connected with the conduct by a Non-U.S. Holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that it maintains in the United States), in which case such Non-U.S. Holder generally will be subject to U.S. federal income tax on such gain at the same regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, if such holder is a corporation for U.S. federal income tax purposes, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate;

a Non-U.S. Holder is an individual who is present in the United States for one hundred eighty-three (183) days or more in the taxable year of the redemption and certain other conditions are met, in which case such holder will be subject to a 30% tax on its net capital gain for the year; or

New Benson Hill is or has been a “United States real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five-year period ending on the date of disposition or the Non-U.S. Holder’s holding period for such securities disposed of, and either (A) shares of New Benson Hill Common Stock are not considered to be regularly traded on an established securities market or (B) a Non-U.S. Holder has owned (or are deemed to have owned), at any time during the shorter of the five-year period preceding such disposition and its holding period, more than 5% of the outstanding shares of New Benson Hill Common Stock. There can be no assurance that shares of New Benson Hill Common Stock will be treated as regularly traded on an established securities market for this purpose.

If the last bullet point immediately above applies, any gain that a Non-U.S. Holder recognizes on the sale, exchange or other disposition of New Benson Hill Common Stock generally will be subject to tax at generally applicable U.S. federal income tax rates. In addition, a buyer of such New Benson Hill Common Stock from a Non-U.S. Holder may be required to withhold U.S. income tax at a rate of 15% of the amount realized upon such disposition. New Benson Hill will generally be classified as a “U.S. real property holding corporation” if the fair market value of its “United States real property interests” equals or exceeds 50% of the sum of the fair market value of its worldwide real property interests and its other assets used or held for use in a trade or business, as determined for U.S. federal income tax purposes. New Benson Hill does not expect to be classified as a “U.S. real property holding corporation” following the merger, but such determination is factual in nature and subject to change, and no assurance can be provided as to whether New Benson Hill is or will be a U.S. real property holding corporation with respect to a Non-U.S. Holder following the merger or at any future time.

Tax Consequences for Non-U.S. Holders of Earn Out Shares

For Non-U.S. Holders, the characterization for U.S. federal income tax purposes of the receipt or forfeiture of the Earn Out Shares generally will correspond to the U.S. federal income tax characterization

211

of such receipt or forfeiture as described above under “ — Tax Consequences to U.S. Holders — Tax Consequences for U.S. Holders of Earn Out Shares.”

Non-U.S. Holders of Existing Benson Hill Common Stock should consult their tax advisors as to the tax consequences to them of the receipt or forfeiture of the Earn Out Shares under such holder’s particular circumstances.

Foreign Account Tax Compliance Act

Sections 1471 through 1474 of the Code and the U.S. Treasury regulations and administrative guidance promulgated thereunder (commonly referred as the “Foreign Account Tax Compliance Act” or “FATCA”) generally impose withholding at a rate of 30% in certain circumstances on dividends in respect of, and (subject to the proposed Treasury regulations discussed below) gross proceeds from the sale or other disposition of, securities (including New Benson Hill Common Stock) which are held by or through certain foreign financial institutions (including investment funds), unless any such institution (i) enters into, and complies with, an agreement with the IRS to report, on an annual basis, information with respect to interests in, and accounts maintained by, the institution that are owned by certain U.S. persons and by certain non-U.S. entities that are wholly or partially owned by U.S. persons and to withhold on certain payments, or (ii) if required under an intergovernmental agreement between the United States and an applicable foreign country, reports such information to its local tax authority, which will exchange such information with the U.S. authorities. An intergovernmental agreement between the United States and an applicable foreign country may modify these requirements. Accordingly, the entity through which STPC public shares and New Benson Hill Common Stock are held will affect the determination of whether such withholding is required. Similarly, dividends in respect of, and (subject to the proposed Treasury regulations discussed below) gross proceeds from the sale or other disposition of, STPC public shares and New Benson Hill Common Stock held by an investor that is a non-financial non-U.S. entity that does not qualify under certain exceptions will generally be subject to withholding at a rate of 30%, unless such entity either (i) certifies to the applicable withholding agent that such entity does not have any “substantial United States owners” or (ii) provides certain information regarding the entity’s “substantial United States owners,” which will in turn be provided to the U.S. Department of Treasury.

Under the applicable U.S. Treasury regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends in respect of our securities. While withholding under FATCA generally would also apply to payments of gross proceeds from the sale or other disposition of securities (including New Benson Hill Common Stock), proposed Treasury regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury regulations until final Treasury regulations are issued. All holders should consult their tax advisors regarding the possible implications of FATCA on their investment in STPC public shares or New Benson Hill Common Stock.

Tax Consequences for Non-U.S. Holders of STPC Public Shares

The discussion below applies to “Non-U.S. Holders” of STPC public shares that exercise the redemption rights described above under “STPC Special Meeting of Stockholders — Redemption Rights.”

Treatment of Redemption of Non-U.S. Holders of STPC Public Shares

For a Non-U.S. Holder, the characterization for U.S. federal income tax purposes of the redemption of STPC public shares generally will correspond to the U.S. federal income tax characterization of such a redemption of a U.S. Holder’s STPC public shares, as described above under “ — Tax Consequences to U.S. Holders — Treatment of Redemption of STPC Public Shares.”

Non-U.S. Holders considering exercising their redemption rights are urged to consult their own tax advisors as to whether the redemption of their STPC public shares will be treated as a distribution or as a sale under the Code.

Taxation of Redemptions Treated as Distributions on STPC Public Shares

If a redemption of STPC public shares does not qualify as a sale or exchange of STPC public shares, Non-U.S. Holders will be treated as receiving a distribution from STPC, which distribution will be treated as a

212

dividend to the extent the distribution is paid out of STPC’s current or accumulated earnings and profits (as determined under U.S. federal income tax principles). The gross amount of such dividends will be subject to a withholding tax at a rate of 30% unless Non-U.S. Holders are eligible for a reduced rate of withholding under an applicable income tax treaty and provide proper certification of their eligibility for such reduced rate.

Dividends that are effectively connected with the conduct by a Non-U.S. Holder of a trade or business in the United States (and are attributable to a U.S. permanent establishment if an applicable treaty so requires) generally will be subject to U.S. federal income tax at the same regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, if a Non-U.S. Holder is a corporation for U.S. federal income tax purposes, may also be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

Distributions in excess of such earnings and profits generally will be treated as a return of capital that will be applied against and reduce a Non-U.S. Holder’s basis in its shares (but not below zero), with any remaining excess treated as gain from the sale or exchange of such shares as described under “— Gain or Loss on Redemptions Treated as a Sale or Exchange of STPC Public Shares” below.

Gain or Loss on Redemptions Treated as a Sale or Exchange of STPC Public Shares

If a redemption of STPC public shares qualifies as a sale or exchange of such shares, Non-U.S. Holders generally will not be subject to U.S. federal income tax on any gain recognized on such redemption unless:

•

such gain is effectively connected with the conduct by a Non-U.S. Holder of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that it maintains in the United States), in which case such Non-U.S. Holder generally will be subject to U.S. federal income tax on such gain at the same regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, if such holder is a corporation for U.S. federal income tax purposes, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate;

•

a Non-U.S. Holder is an individual who is present in the United States for one hundred eighty-three (183) days or more in the taxable year of the redemption and certain other conditions are met, in which case such holder will be subject to a 30% tax on its net capital gain for the year; or

•

we are or have been a “U.S. real property holding corporation” for U.S. federal income tax purposes at any time during the shorter of the five (5) year period ending on the date of the redemption or the period during which a Non-U.S. Holder held STPC public shares, and, in the case where our STPC public shares are traded on an established securities market, it has owned, directly or constructively, more than 5% of our STPC public shares at any time within the shorter of the five (5) year period or its holding period for our STPC public shares. We do not believe that we are or have been a U.S. real property holding corporation.

All Non-U.S. Holders of Existing Benson Hill Common Stock and of STPC public shares are urged to consult their tax advisors with respect to the tax consequences of the merger and of a redemption of their STPC public shares, as applicable, in their particular circumstances, including tax return reporting requirements, the applicability and effect of the alternative minimum tax, any federal tax laws other than those pertaining to income tax (including estate and gift tax laws), and any state, local, foreign or other tax laws.

Information Reporting and Backup Withholding

Proceeds received in connection with the merger, a redemption of STPC public shares or any sale, exchange, redemption or other taxable disposition of New Benson Hill Common Stock or any dividends received in respect of New Benson Hill Common Stock may be subject to information reporting to the IRS and U.S. backup withholding. Backup withholding generally will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status. A Non-U.S. Holder generally will eliminate the requirement for information reporting for any sales proceeds and any backup withholding

213

by providing certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s U.S. federal income tax liability, and a holder generally may claim a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

214

Limitation of Liability of Directors and Officers
A director of STPC shall not be personally liable to STPC or its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended unless they violated their duty of loyalty to STPC or its stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived improper personal benefit from their actions as directors.

Subject to applicable law, the rights, if any, of the holders of any outstanding series of the Preferred Stock and the business combination redemption rights provided under Article IX of STPC’s Existing Charter, in the event of any voluntary or involuntary liquidation, dissolution or winding up of STPC, after payment or provision for payment of the debts and other liabilities of STPC, the holders of shares of common stock shall be entitled to receive all the remaining assets of STPC available for distribution to its stockholders, ratably in proportion to the number of shares of Class A Common Stock (on an as converted basis with respect to the Class B Common Stock) held by them.

DESCRIPTION OF NEW BENSON HILL CAPITAL STOCK

As a result of the merger, STPC stockholders and Benson Hill stockholders who receive shares of New Benson Hill Common Stock in the merger will become stockholders of New Benson Hill. Your rights as New Benson Hill stockholders will be governed by Delaware law and New Benson Hill’s Proposed Charter and amended and restated bylaws. The following summary of the material terms of our securities is not intended to be a complete summary of the rights and preferences of such securities. We urge you to read the applicable provisions of Delaware law and New Benson Hill’s Proposed Charter and form of amended and restated bylaws carefully and in their entirety because they describe your rights as a holder of shares of New Benson Hill Common Stock.

Common Stock

Holders of New Benson Hill Common Stock are entitled to one (1) vote for each share held of record on all matters properly submitted to a vote of stockholders, including the election or removal of directors. Unless specified in the Proposed Charter or amended and restated bylaws, or as required by applicable provisions of the DGCL or applicable stock exchange rules, the affirmative vote of a majority of the votes cast at any meeting of the New Benson Hill stockholders at which there is a quorum is required to approve any such matter voted on by its stockholders. Each of New Benson Hill’s directors will generally serve for a term of one (1) year, with all directors being elected at each annual meeting of stockholders to hold office until the next annual meeting. Our stockholders do not have cumulative voting rights in the election of directors. Accordingly, holders of a majority of the voting shares are able to elect all of the directors. Stockholders are entitled to receive ratable dividends, if any, as may be declared from time-to-time by our board of directors out of legally available assets or funds.

Redeemable Warrants

The warrants were issued in registered form under a warrant agreement between CST, as warrant agent, and New Benson Hill (the “Warrant Agreement”). The Warrant Agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least a majority of the then-outstanding public warrants to make any change that adversely affects the interests of the registered holders of public warrants.

The warrants may be exercised upon surrender of the warrant certificate on or prior to the expiration date at the offices of the warrant agent, with the exercise form on the reverse side of the warrant certificate completed and executed as indicated, accompanied by full payment of the exercise price (or on a cashless basis, if applicable), by certified check payable to New Benson Hill or by wire transfer, for the number of warrants being exercised. The warrantholders do not have the rights or privileges of holders of New Benson Hill Common Stock and any voting rights until they exercise their warrants and receive shares of New Benson Hill Common Stock. After the issuance of shares of New Benson Hill Common Stock upon exercise of the warrants, each holder will be entitled to one (1) vote for each share held of record on all matters to be voted on by stockholders.

In addition, if (x) New Benson Hill issues additional shares of New Benson Hill Common Stock or equity-linked securities for capital raising purposes in connection with the closing of the initial business combination at a Newly Issued Price (as defined in the Warrant Agreement) of less than $9.20 per share of New Benson Hill Common Stock (with such issue price or effective issue price to be determined in good faith by New Benson Hill’s board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the Market Value (as defined in the Warrant Agreement) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price. No fractional shares will be issued upon exercise of the warrants. If, upon exercise of the warrants, a holder would be entitled to

231

receive a fractional interest in a share, New Benson Hill will, upon exercise, round down to the nearest whole number of shares of New Benson Hill Common Stock to be issued to the warrantholder.

Each whole warrant entitles the registered holder to purchase one (1) whole share of New Benson Hill Common Stock at a price of $11.50 per share, subject to adjustment as discussed below, 30 days after the completion of the initial business combination. Pursuant to the Warrant Agreement, a warrantholder may exercise its warrants only for a whole number of shares of New Benson Hill Common Stock. This means that only a whole warrant may be exercised at any given time by a warrantholder. Only whole warrants are traded.

The warrants will expire five (5) years after the completion of the initial business combination, at 5:00 p.m. Eastern Time or earlier upon redemption or liquidation.

New Benson Hill will not be obligated to deliver any shares of New Benson Hill Common Stock pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the shares of New Benson Hill Common Stock underlying the warrants is then effective and a prospectus relating thereto is current, subject to New Benson Hill’s satisfying New Benson Hill’s obligations described below with respect to registration. No warrant is exercisable and New Benson Hill will not be obligated to issue shares of New Benson Hill Common Stock upon exercise of a warrant unless New Benson Hill Common Stock issuable upon such warrant exercise has been registered, qualified, or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In the event that the conditions in the two immediately preceding sentences are not satisfied with respect to a warrant, the holder of such warrant will not be entitled to exercise such warrant and such warrant may have no value and expire worthless. In no event will New Benson Hill be required to net cash settle any warrant. In the event that a registration statement is not effective for the exercised warrants, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of New Benson Hill Common Stock underlying such unit.

New Benson Hill has agreed that as soon as practicable, but in no event later than twenty (20) business days after the closing of the initial business combination, New Benson Hill will use its best efforts to file with the SEC a registration statement covering the shares of New Benson Hill Common Stock issuable upon exercise of the warrants, to cause such registration statement to become effective and to maintain a current prospectus relating to those shares of New Benson Hill Common Stock until the warrants expire or are redeemed, as specified in the Warrant Agreement. If a registration statement covering the shares of New Benson Hill Common Stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of the initial business combination, warrantholders may, until such time as there is an effective registration statement and during any period when New Benson Hill will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the foregoing, if a registration statement covering the New Benson Hill Common Stock issuable upon exercise of the warrants is not effective within a specified period following the consummation of the initial business combination, warrantholders may, until such time as there is an effective registration statement and during any period when New Benson Hill shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, as amended, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis.

Once the warrants become exercisable, New Benson Hill may call the warrants for redemption:

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

upon not less than 30 days’ prior written notice of redemption (the “30-day redemption period”) to each warrantholder; and

•

if, and only if, the reported last sale price of the New Benson Hill Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-trading day period ending three (3) business days before New Benson Hill sends the notice of redemption to the warrantholders.

232

If and when the warrants become redeemable, New Benson Hill may not exercise its redemption right if the issuance of shares of New Benson Hill Common Stock upon exercise of the warrants is not exempt from registration or qualification under applicable state blue sky laws or New Benson Hill are unable to effect such registration or qualification.

New Benson Hill established the last of the redemption criteria discussed above to prevent a redemption call unless there is, at the time of the call, a significant premium to the warrant exercise price. If the foregoing conditions are satisfied and New Benson Hill issues a notice of redemption of the warrants, each warrantholder is entitled to exercise its warrant prior to the scheduled redemption date. However, the price of the New Benson Hill Common Stock may fall below the $18.00 redemption trigger price (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) as well as the $11.50 warrant exercise price after the redemption notice is issued.

If New Benson Hill calls the warrants for redemption as described above, New Benson Hill’s management will have the option to require any holder that wishes to exercise its warrant to do so on a “cashless basis.” In determining whether to require all holders to exercise their warrants on a “cashless basis,” management will consider, among other factors, New Benson Hill cash position, the number of warrants that are outstanding and the dilutive effect on its stockholders of issuing the maximum number of shares of New Benson Hill Common Stock issuable upon the exercise of New Benson Hill’s warrants. If New Benson Hill’s management takes advantage of this option, all holders of warrants would pay the exercise price by surrendering their warrants for that number of shares of New Benson Hill Common Stock equal to (A) the quotient obtained by dividing (x) the product of the number of shares of New Benson Hill Common Stock underlying the warrants, multiplied by the excess of the “fair market value” ​(defined below) less the Warrant Price (as defined in the Warrant Agreement) by (y) the fair market value and (B) .361. The “fair market value” shall mean the average reported last sale price of the New Benson Hill Common Stock for the ten (10) trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants. If New Benson Hill’s management takes advantage of this option, the notice of redemption will contain the information necessary to calculate the number of shares of New Benson Hill Common Stock to be received upon exercise of the warrants, including the “fair market value” in such case. Requiring a cashless exercise in this manner will reduce the number of shares to be issued and thereby lessen the dilutive effect of a warrant redemption. New Benson Hill believes this feature is an attractive option to it if it does not need the cash from the exercise of the warrants after the initial business combination. If New Benson Hill calls its warrants for redemption and its management does not take advantage of this option, the Sponsor and its permitted transferees would still be entitled to exercise their Private Placement Warrants for cash or on a cashless basis using the same formula described above that other warrantholders would have been required to use had all warrantholders been required to exercise their warrants on a cashless basis, as described in more detail below.

A holder of a warrant may notify New Benson Hill in writing in the event it elects to be subject to a requirement that such holder will not have the right to exercise such warrant, to the extent that, to the warrant agent’s actual knowledge, after giving effect to such exercise, such person (together with such person’s affiliates) would beneficially own in excess of 9.8% (or such other amount as a holder may specify) of the shares of New Benson Hill Common Stock outstanding immediately after giving effect to such exercise.

If the number of outstanding shares of New Benson Hill Common Stock is increased by a stock dividend payable in shares of New Benson Hill Common Stock, or by a split-up of shares of New Benson Hill Common Stock or other similar event, then, on the effective date of such stock dividend, split-up or similar event, the number of shares of New Benson Hill Common Stock issuable on exercise of each warrant will be increased in proportion to such increase in the outstanding shares of New Benson Hill Common Stock. A rights offering to holders of New Benson Hill Common Stock entitling holders to purchase shares of New Benson Hill Common Stock at a price less than the fair market value will be deemed a stock dividend of a number of shares of New Benson Hill Common Stock equal to the product of (i) the number of shares of New Benson Hill Common Stock actually sold in such rights offering (or issuable under any other equity securities sold in such rights offering that are convertible into or exercisable for New Benson Hill Common Stock) and (ii) one (1) minus the quotient of (x) the price per share of New Benson Hill Common Stock paid in such rights offering divided by (y) the fair market value. For these purposes (i) if the rights offering is for securities convertible into or exercisable for New Benson Hill Common Stock, in

233

determining the price payable for New Benson Hill Common Stock, there will be taken into account any consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) fair market value means the volume weighted average price of New Benson Hill Common Stock as reported during 10 trading day period ending on the trading day prior to the first date on which the shares of New Benson Hill Common Stock trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.

In addition, if New Benson Hill, at any time while the warrants are outstanding and unexpired, pay a dividend or make a distribution in cash, securities, or other assets to the holders of New Benson Hill Common Stock on account of such shares of New Benson Hill Common Stock (or other shares of New Benson Hill’s capital stock into which the warrants are convertible), other than (a) as described above, (b) certain ordinary cash dividends, (c) to satisfy the redemption rights of the holders of New Benson Hill Common Stock in connection with a proposed initial business combination, (d) to satisfy the redemption rights of the holders of New Benson Hill Common Stock in connection with a stockholder vote to amend the Existing Charter (i) to modify the substance or timing of New Benson Hill’s obligation to redeem 100% of its New Benson Hill Common Stock if it does not complete the initial business combination within the timeframe set forth in its amended and restated certificate of incorporation or (ii) with respect to any other provision relating to stockholders’ rights or pre-initial business combination activity, or (e) in connection with the redemption of New Benson Hill’s common stock upon its failure to complete the initial business combination, then the warrant exercise price will be decreased, effective immediately after the effective date of such event, by the amount of cash and/or the fair market value of any securities or other assets paid on each share of New Benson Hill Common Stock in respect of such event.

If the number of outstanding shares of New Benson Hill Common Stock is decreased by a consolidation, combination, reverse stock split or reclassification of shares of New Benson Hill Common Stock or other similar event, then, on the effective date of such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of New Benson Hill Common Stock issuable on exercise of each warrant will be decreased in proportion to such decrease in outstanding shares of New Benson Hill Common Stock.

Whenever the number of shares of New Benson Hill Common Stock purchasable upon the exercise of the warrants is adjusted, as described above, the warrant exercise price will be adjusted by multiplying the warrant exercise price immediately prior to such adjustment by a fraction (x) the numerator of which will be the number of shares of New Benson Hill Common Stock purchasable upon the exercise of the warrants immediately prior to such adjustment, and (y) the denominator of which will be the number of shares of New Benson Hill Common Stock so purchasable immediately thereafter.

In case of any reclassification or reorganization of the outstanding shares of New Benson Hill Common Stock (other than those described above or that solely affects the par value of such shares of New Benson Hill Common Stock), or in the case of any merger or consolidation of us with or into another corporation (other than a consolidation or merger in which New Benson Hill is the continuing corporation and that does not result in any reclassification or reorganization of its outstanding shares of New Benson Hill Common Stock), or in the case of any sale or conveyance to another corporation or entity of the assets or other property of us as an entirety or substantially as an entirety in connection with which New Benson Hill are dissolved, the warrantholders will thereafter have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the warrants and in lieu of the shares of New Benson Hill Common Stock immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares of stock or other securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the warrants would have received if such holder had exercised their warrants immediately prior to such event. If less than 70% of the consideration receivable by the holders of New Benson Hill Common Stock in such a transaction is payable in the form of New Benson Hill Common Stock in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter market, or is to be so listed for trading or quoted immediately following such event, and if the registered holder of the warrant properly exercises the warrant within 30 days following public disclosure of such transaction, the warrant exercise price will be reduced as specified in the Warrant Agreement based on the Black-Scholes value (as defined in the Warrant Agreement) of the warrant. The

234

purpose of such exercise price reduction is to provide additional value to warrantholders when an extraordinary transaction occurs during the exercise period of the warrants pursuant to which the warrantholders otherwise do not receive the full potential value of the warrants in order to determine and realize the option value component of the warrant. This formula is to compensate the warrantholder for the loss of the option value portion of the warrant due to the requirement that the warrantholder exercise the warrant within 30 days of the event. The Black-Scholes model is an accepted pricing model for estimating fair market value where no quoted market price for an instrument is available.

Annual Stockholder Meetings

New Benson Hill will provide that annual stockholder meetings will be held at a date, time and place, if any, as exclusively selected by New Benson Hill’s board of directors. To the extent permitted under applicable law, New Benson Hill may conduct meetings by means of remote communication.

Anti-Takeover Effects of New Benson Hill’s Proposed Charter and Bylaws and Certain Provisions of Delaware Law

New Benson Hill’s Proposed Charter and amended and restated bylaws will contain and the DGCL contains provisions, as summarized in the following paragraphs that are intended to enhance the likelihood of continuity and stability in the composition of New Benson Hill’s board of directors. These provisions are intended to avoid costly takeover battles, reduce New Benson Hill’s vulnerability to a hostile change of control and enhance the ability of New Benson Hill’s board of directors to maximize stockholder value in connection with any unsolicited offer to acquire New Benson Hill. However, these provisions may have an anti-takeover effect and may delay, deter, or prevent a merger or acquisition of New Benson Hill by means of a tender offer, a proxy contest or other takeover attempt that a stockholder might consider in its best interest, including those attempts that might result in a premium over the prevailing market price for the shares of New Benson Hill Common Stock held by stockholders.

•

Issuance of undesignated preferred stock: Under New Benson Hill’s Proposed Charter, New Benson Hill’s board of directors will have the authority, without further action by the stockholders, to issue up to 1,000,000 shares of undesignated preferred stock with rights and preferences, including voting rights, designated from time to time by New Benson Hill’s board of directors. The existence of authorized but unissued shares of preferred stock enables New Benson Hill’s board of directors to make it more difficult to attempt to obtain control of us by means of a merger, tender offer, proxy contest or otherwise.

•

Election and removal of directors and board vacancies: New Benson Hill’s Proposed Charter will provide that, in the event of a contested election, directors will be elected by a plurality vote. New Benson Hill’s Proposed Charter and amended and restated bylaws will also provide that New Benson Hill’s board of directors has the right to increase or decrease the size of the board of directors, provided there are at least five and no more than fifteen directors, and to fill vacancies on the board. Directors may be removed only for cause by the affirmative vote of the holders of at least a majority of the voting power of the outstanding shares of capital stock of New Benson Hill entitled to vote generally in the election of directors. Only New Benson Hill’s board of directors is authorized to fill vacant directorships. In addition, the number of directors constituting New Benson Hill’s board of directors may be set only by resolution adopted by a majority vote of the directors then in office. These provisions prevent stockholders from increasing the size of New Benson Hill’s board of directors and gaining control of New Benson Hill’s board of directors by filling the resulting vacancies with its own nominees.

•

Requirements for advance notification of stockholder nominations and proposals: New Benson Hill’s amended and restated bylaws will establish advance notice procedures with respect to stockholder proposals and the nomination of candidates for election as directors that specify certain requirements as to the timing, form and content of a stockholder’s notice. Business that may be conducted at an annual meeting of stockholders will be limited to those matters properly brought before the meeting. These provisions may make it more difficult for our stockholders to bring matters before our annual meeting of stockholders or to nominate directors at annual meetings of stockholders.

235

•

No written consent of stockholders: New Benson Hill’s Proposed Charter will provide that all stockholder actions be taken by a vote of the stockholders at an annual or special meeting, and that stockholders may not take any action by written consent in lieu of a meeting. This limit may lengthen the amount of time required to take stockholder actions and would prevent the amendment of our amended and restated bylaws or removal of directors by our stockholders without holding a meeting of stockholders.

•

No stockholder ability to call special meetings: New Benson Hill’s Proposed Charter and amended and restated bylaws will provide that only New Benson Hill’s board of directors may call special meetings of stockholders and only those matters set forth in the notice of the special meeting may be considered or acted upon at a special meeting of stockholders.

•

Amendments to certificate of incorporation and bylaws: New Benson Hill’s Proposed Charter will provide that, prior to            , 2024, the affirmative vote of at least 662∕3% of the voting power of the outstanding shares of capital stock entitled to vote thereon, voting together as a single class, shall be required to (A) adopt, amend or repeal the bylaws or (B) to amend or repeal articles in the Proposed Charter related to the board of directors, amendments of New Benson Hill’s governing documents, stockholder actions, limitation of director liability and indemnification, business combinations, corporate opportunity, forum selection and certain miscellaneous provisions. Following            , 2024, the bylaws may be adopted, amended or repealed, and such provisions of the Proposed Charter may be amended or repealed, by the affirmative vote of the majority of the voting power of the outstanding shares of capital stock entitled to vote thereon, voting together as a single class. Notwithstanding the foregoing, the bylaws may at all times be adopted, altered, amended or repealed by the affirmative vote of a majority of New Benson Hill’s board of directors.

These provisions are designed to enhance the likelihood of continued stability in the composition of New Benson Hill’s board of directors and its policies, to discourage certain types of transactions that may involve an actual or threatened acquisition of our company and to reduce our vulnerability to an unsolicited acquisition proposal. We also designed these provisions to discourage certain tactics that may be used in proxy fights. However, these provisions could have the effect of discouraging others from making tender offers for our shares and, as a consequence, they may also reduce fluctuations in the market price of our shares that could result from actual or rumored takeover attempts.

Delaware General Corporation Law Section 203

As a Delaware corporation, we are also subject to the anti-takeover provisions of Section 203 of the DGCL, which prohibits a Delaware corporation from engaging in a business combination specified in the statute with an interested stockholder (as defined in the statute) for a period of three (3) years after the date of the transaction in which the person first becomes an interested stockholder, unless the business combination is approved in advance by a majority of the independent directors or by the holders of at least two-thirds of the outstanding disinterested shares. The application of Section 203 of the DGCL could also have the effect of delaying or preventing a change of control of us.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, New Benson Hill’s stockholders have appraisal rights in connection with a merger or consolidation of New Benson Hill. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

Stockholders’ Derivative Actions

Under the DGCL, any of New Benson Hill’s stockholders may bring an action in New Benson Hill’s name to procure a judgment in New Benson Hill’s favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of New Benson Hill’s shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

236

Exclusive Forum

New Benson Hill’s Proposed Charter will provide that, unless we consent in writing to the selection of an alternative forum, the sole and exclusive forum, to the fullest extent permitted by law, for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (3) any action asserting a claim against us or any director, officer, or other employee arising pursuant to the DGCL, (4) any action to interpret, apply, enforce, or determine the validity of our second amended and restated certificate of incorporation or amended and restated bylaws, or (5) any other action asserting a claim that is governed by the internal affairs doctrine, shall be the Court of Chancery of the State of Delaware (or another state court or the federal court located within the State of Delaware if the Court of Chancery does not have or declines to accept jurisdiction), in all cases subject to the court’s having jurisdiction over indispensable parties named as defendants. In addition, New Benson Hill’s Proposed Charter will provide that the federal district court for the District of Delaware (or, in the event such court does not have jurisdiction, the federal district courts of the United States) will be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act but that the forum selection provision will not apply to claims brought to enforce a duty or liability created by the Exchange Act. Although we believe these provisions benefit New Benson Hill by providing increased consistency in the application of Delaware law for the specified types of actions and proceedings, the provisions may have the effect of discouraging lawsuits against us or our directors and officers. Although our Proposed Charter contains the choice of forum provisions described above, it is possible that a court could find that such provisions are inapplicable for a particular claim or action or that such provisions are unenforceable.

Conflicts of Interest

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors, or stockholders. The Proposed Charter, to the extent allowed by Delaware law, renounces any interest or expectancy that New Benson Hill has in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to New Benson Hill’s officers, directors or their respective affiliates in circumstances where the application of any such doctrine would conflict with any fiduciary duties or contractual obligations they may have, and New Benson Hill renounces any expectancy that any of the directors or officers of New Benson Hill will offer any such corporate opportunity of which they may become aware to New Benson Hill, except with respect to any of the directors or officers of New Benson Hill regarding a corporate opportunity that was offered to such person solely in his or her capacity as a director or officer of New Benson Hill and (i) such opportunity is one New Benson Hill is legally and contractually permitted to undertake and would otherwise be reasonable for it to pursue and (ii) the director or officer is permitted to refer that opportunity to New Benson Hill without violating any legal obligation.

Limitations on Liability and Indemnification of Officers and Directors

The DGCL authorizes corporations to limit or eliminate the personal liability of directors to corporations and their stockholders for monetary damages for breaches of directors’ fiduciary duties, subject to certain exceptions. The Proposed Charter includes a provision that eliminates the personal liability of directors for monetary damages for any breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The effect of these provisions is to eliminate the rights of New Benson Hill and its stockholders, through stockholders’ derivative suits on New Benson Hill’s behalf, to recover monetary damages from a director for breach of fiduciary duty as a director, including breaches resulting from grossly negligent behavior. However, exculpation does not apply to any director if the director has acted in bad faith, knowingly or intentionally violated the law, authorized illegal dividends or redemptions or derived an improper benefit from his or her actions as a director.

New Benson Hill’s amended and restated bylaws provide that New Benson Hill must indemnify and advance expenses to New Benson Hill’s directors and officers to the fullest extent authorized by the DGCL. New Benson Hill also is expressly authorized to carry directors’ and officers’ liability insurance providing indemnification for New Benson Hill’s directors, officers and certain employees for some liabilities. New Benson Hill believes that these indemnification and advancement provisions and insurance are useful to attract and retain qualified directors and executive officers.

237

The limitation of liability, advancement and indemnification provisions in the Proposed Charter and amended and restated bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty.

These provisions also may have the effect of reducing the likelihood of derivative litigation against directors and officers, even though such an action, if successful, might otherwise benefit New Benson Hill and its stockholders. In addition, your investment may be adversely affected to the extent New Benson Hill pays the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

There is currently no pending material litigation or proceeding involving New Benson Hill’s directors, officers or employees for which indemnification is sought.

238

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of
Star Peak Corp II

Opinion on the Financial Statements

We have audited the accompanying balance sheet of Star Peak Corp II (the “Company”), as of December 31, 2020, the related statements of operations, changes in stockholders’ equity and cash flows for the period from October 8, 2020 (inception) through December 31, 2020, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2020, and the results of its operations and its cash flows for the period from October 8, 2020, 2020 (inception) through December 31, 2020, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

/s/ WithumSmith+Brown, PC

We have served as the Company’s auditor since 2020.

STAR PEAK CORP II
NOTES TO FINANCIAL STATEMENTS

Note 1 — Description of Organization and Business Operations

Star Peak Corp II (the “Company”) is a blank check company incorporated in Delaware on October 8, 2020, for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of December 31, 2020, the Company had not commenced any operations. All activity for the period from October 8, 2020 (inception) through December 31, 2020 relates to the Company’s formation and the initial public offering (“Initial Public Offering”) described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on cash and cash equivalents from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is Star Peak Sponsor II LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on January 5, 2021. On January 8, 2021, the Company consummated its Initial Public Offering of 40,250,000 units (the “Units” and, with respect to the Class A common stock included in the Units being offered, the “Public Shares”), including 5,250,000 additional Units to cover over-allotments (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.9 million, inclusive of approximately $14.1 million in deferred underwriting commissions (Note 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 6,553,454 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $2.00 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $13.1 million (Note 4).

Upon the closing of the Initial Public Offering and the Private Placement, $402.5 million ($10.00 per Unit) of the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was held in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting discounts and commissions held in trust and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-business combination company owns or acquires 50% or more of the voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide the holders (the “Public Stockholders”) of the Public Shares with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business

F-7

Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares will be recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” The Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the Initial Stockholders (as defined below) agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Stockholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Amended and Restated Certificate of Incorporation will provide that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” ​(as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The Sponsor and the Company’s officers and directors (the “Initial Stockholders”) agreed not to propose an amendment to the Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or January 8, 2023 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, including franchise and income taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Initial Stockholders agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Stockholders acquire Public Shares in or after the

F-8

Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. The underwriters agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) not will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Liquidity and Capital Resources

As of December 31, 2020, the Company had approximately $45,000 in cash, and working capital deficit of approximately $429,000 (not taking into account tax obligations of approximately $2,000 that may be paid using investment income earned in Trust Account).

The Company’s liquidity needs to date have been satisfied through the payment of $25,000 from the Sponsor to cover certain offering costs on behalf of the Company in exchange for issuance of Founders Shares (as defined in Note 4), and loan proceeds from the Sponsor of $150,000 under the Note (Note 4). The Company repaid the Note in full on January 8, 2021. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity needs have been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account.

Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using the funds held outside of the Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the SEC.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage

F-9

of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards.

The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s financial statement with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash equivalents as of December 31, 2020.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Depository Insurance coverage limits of $250,000. At December 31, 2020, the Company has not experienced losses on this account and management believes the Company is not exposed to significant risks on the account.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurements”, approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature.

Deferred Offering Costs Associated with the Initial Public Offering

Deferred offering costs consist of legal, accounting, and other costs incurred as of December 31, 2020 that were directly related to the Initial Public Offering and that were charged to stockholders’ equity upon the completion of the Initial Public Offering on January 8, 2021. As of December 31, 2020, the Company incurred approximately $450,000 of deferred offering costs.

Net Loss Per Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” Net loss per share is computed by dividing net loss by the weighted average number of shares of common stock outstanding during the period, excluding common stock subject to forfeiture.

F-10

Weighted average shares at December 31, 2020 were reduced for the effect of an aggregate of 1,312,500 shares of common stock that are subject to forfeiture if the over-allotment option was not exercised in full or in part by the underwriters (see Note 6). At December 31, 2020, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into shares of common stock and then share in the earnings of the Company. As a result, diluted loss per share is the same as basic loss per share for the period presented.

Income Taxes

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740, “Income Taxes.” Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Deferred tax assets were deemed immaterial as of December 31, 2020.

FASB ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as of December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as of December 31, 2020. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

The provision for income taxes are de minimis for the year ended December 31, 2020

Recent Accounting Pronouncements

The Company’s management does not believe that any recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Note 3 — Initial Public Offering

On January 8, 2021, the Company consummated its Initial Public Offering of 40,250,000 Units, including 5,250,000 Over-Allotment Units, at $10.00 per Unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.9 million, inclusive of approximately $14.1 million in deferred underwriting commissions.

Each Unit consists of one share of Class A common stock and one-fourth of one redeemable warrant (each, a “Public Warrant”). Each whole Public Warrant entitles the holder to purchase one share of Class A common stock at a price of $11.50 per share, subject to adjustment (see Note 6).

Note 4 — Related Party Transactions

Founder Shares

On October 23, 2020, the Sponsor paid $25,000 on behalf of the Company to cover certain offering costs in exchange for issuance of 10,062,500 shares of the Company’s Class B common stock, par value $0.0001 per share (the “Founder Shares”). Subsequent to October 23, 2020, the Sponsor transferred an aggregate of 80,000 Founder Shares to the Company’s independent directors. The Sponsor and independent directors are referred to as the “Initial Stockholders.”

The Initial Stockholders agreed to forfeit up to 1,312,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent

F-11

20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriters exercised the over-allotment option in full on January 8, 2021; thus, these 1,312,500 Founder Shares are no longer subject to forfeiture.

The Initial Stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination; or (B) subsequent to the initial Business Combination, (x) if the closing price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 6,553,454 Private Placement Warrants at a price of $2.00 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $13.1 million.

Each whole Private Placement Warrant is exercisable for one whole share of Class A common stock at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants to the Sponsor was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable for cash and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Loans

On October 23, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed $150,000 under the Note and repaid the Note in full on January 8, 2021.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lenders’ discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $2.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of December 31, 2020, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

The Company entered into an agreement that provided that, commencing on the effective date of the Initial Public Offering through the earlier of consummation of the initial Business Combination and the

F-12

Company’s liquidation, the Company agreed to pay the Sponsor a total of $10,000 per month for office space, utilities, secretarial support and administrative services.

The Company’s officers or directors will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. The Company’s audit committee will review on a quarterly basis all payments that were made to the Sponsor, officers or directors, or the Company’s or their affiliates. Any such payments prior to an initial Business Combination will be made using funds held outside the Trust Account.

Note 5 — Commitments and Contingencies

Registration Rights

The holders of Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans, if any, (and any shares of Class A common stock issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) were entitled to registration rights pursuant to a registration rights agreement signed upon the consummation of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a 45-day option from the date of Initial Public Offering to purchase up to 5,250,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. The underwriters exercised the over-allotment option in full on January 8, 2021.

The underwriters were entitled to an underwriting discount of $0.20 per Unit, or approximately $8.1 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or approximately $14.1 million in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of the financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Note 6 — Stockholders’ Equity

Class A Common Stock — The Company is authorized to issue 400,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of December 31, 2020, there were no shares of Class A common stock issued or outstanding.

Class B Common Stock — The Company is authorized to issue 40,000,000 shares of Class B common stock with a par value of $0.0001 per share. As of December 31, 2020, there were 10,062,500 shares of Class B common stock issued and outstanding. Of these, up to 1,312,500 shares of Class B common stock were subject to forfeiture to the extent that the underwriters’ over-allotment option was not exercised in full or in part, so that the Initial Stockholders would collectively own 20% of the Company’s issued and outstanding

F-13

common stock after the Initial Public Offering. The underwriter exercised its over-allotment option in full on January 8, 2021; thus, these 1,312,500 shares of Class B common stock are no longer subject to forfeiture.

Prior to the initial Business Combination, only holders of the Class B common stock will have the right to vote on the election of directors. Holders of the Class A common stock will not be entitled to vote on the election of directors during such time. In addition, prior to the completion of an initial Business Combination, holders of a majority of the Class B common stock may remove a member of the board of directors for any reason. These provisions of the amended and restated certificate of incorporation may only be amended by a resolution passed by a majority of the shares of Class B common stock. With respect to any other matter submitted to a vote of the stockholders, including any vote in connection with the initial Business Combination, except as required by law or the applicable rules of the NYSE then in effect, holders of the Class A and Class B common stock will vote together as a single class, with each share entitling the holder to one vote.

The Class B common stock will automatically convert into Class A common stock at the time of the initial Business Combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the initial Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering plus all shares of Class A common stock and equity-linked securities issued or deemed issued in connection with the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination). Holders of Founder Shares may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time.

Preferred Stock — The Company is authorized to issue 1,000,000 shares of preferred stock, par value $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of December 31, 2020, there were no shares of preferred stock issued or outstanding.

Warrants — As of December 31, 2020, there were no warrants issued or outstanding. Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, it will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of the Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of the Class A common stock until the warrants expire or are redeemed. If a registration statement covering the shares of the Class A common stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption.

The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if (x) the Company issues additional shares of the Class A common stock or equity-linked securities

F-14

for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share of the Class A common stock (with such issue price or effective issue price to be determined in good faith by the board of directors and, (i) in the case of any such issuance to the Sponsor or their affiliates, without taking into account any Founder Shares held by the Initial Stockholders or such affiliates, as applicable, prior to such issuance, and (ii) to the extent that such issuance is made to the Sponsor or its affiliates, without taking into account the transfer of Founder Shares or Private Placement Warrants (including if such transfer is effectuated as a surrender to the Company and subsequent reissuance by the Company) by the Sponsor in connection with such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the completion of the initial Business Combination (net of redemptions), and (z) the volume-weighted average trading price of the Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company completes its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $10.00 and $18.00 per share redemption trigger prices described under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00” and “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 100% and 180% of the higher of the Market Value and the Newly Issued Price, respectively.

The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of Class A common stock issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees. If the Private Placement Warrants are held by someone other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00:

Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

upon a minimum of 30 days’ prior written notice of redemption; and

•

if, and only if, the last reported sale price (the “closing price”) of Class A common stock equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

The Company will not redeem the warrants as described above unless an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants is effective and a current prospectus relating to those shares of Class A common stock is available throughout the 30-day redemption period. Any such exercise would not be on a “cashless” basis and would require the exercising holder to pay the exercise price for each warrant being exercised.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00:

Commencing ninety days after the warrants become exercisable, the Company may redeem the outstanding warrants:

•

in whole and not in part;

•

at $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption, provided that holders will be able to exercise their warrants, but only on a cashless basis, prior to redemption and

F-15

receive that number of shares determined by reference to an agreed table based on the redemption date and the “fair market value” of Class A common stock;

•

if, and only if, the closing price of the Class A common stock equals or exceeds $10.00 per Public Share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders; and

•

if the closing price of the Class A common stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

The “fair market value” of Class A common stock for the above purpose shall mean the volume weighted average price of Class A common stock during the 10 trading days ending on the third trading day immediately following the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Class A common stock per warrant (subject to adjustment).

In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 7 — Subsequent Events

The Company evaluated events that have occurred after the balance sheet date through the date on which the financial statements are issued. Based upon this review, the Company did not identify any subsequent events, except as noted above in Note 1, 3, 4, 5 and 6, that would have required adjustment or disclosure in the financial statements.

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Note 1 — Description of Organization and Business Operations

Star Peak Corp II (the “Company”) is a blank check company incorporated in Delaware on October 8, 2020, for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

On March 19, 2021, the Company formed a wholly owned subsidiary, STPC II Merger Sub Corp.,incorporated in Delaware (“Merger Sub”).

As of June 30, 2021, the Company had not commenced any operations. All activity for the period from October 8, 2020 (inception) through June 30, 2021 related to the Company’s formation, the preparation for the Company’s initial public offering (“Initial Public Offering”) described below, and since the closing of the Initial Public Offering, the search for a prospective Business Combination, including activities in connection with the proposed acquisition of Benson Hill, Inc., a Delaware corporation (“Benson Hill”). The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on its investments held in the trust account from the proceeds of its Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s sponsor is Star Peak Sponsor II LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on January 5, 2021. On January 8, 2021, the Company consummated its Initial Public Offering of 40,250,000 units (the “Units” and, with respect to the Class A common stock, par value $0.0001 per share (“Class A common stock”), included in the Units being offered, the “Public Shares”), which includes the full exercise by the underwriters of the over-allotment option to purchase an additional 5,250,000 Units (the “Over-Allotment Units”), at $10.00 per Unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.9 million, inclusive of approximately $14.1 million in deferred underwriting commissions (Notes 2 and 5).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the private placement (“Private Placement”) of 6,553,454 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) at a price of $2.00 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $13.1 million (Notes 4 and 6).

Upon the closing of the Initial Public Offering and the Private Placement, an amount of $402.5 million ($10.00 per Unit) from the net proceeds of the Initial Public Offering and certain of the proceeds of the Private Placement was placed in a trust account (“Trust Account”) located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and invested only in U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries and meeting certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”), as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (excluding the amount of any deferred underwriting discounts and commissions held in trust and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. However, the Company will only complete a Business Combination if the post-business combination company owns or

F-21

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

acquires 50% or more of the voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act.

The Company will provide the holders (the “Public Stockholders”) of the Public Shares with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Stockholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Stockholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriters (as discussed in Note 5). These Public Shares are recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” The Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in an amount that would cause its net tangible assets to be less than $5,000,001. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other reasons, the Company will, pursuant to its amended and restated certificate of incorporation (the “Amended and Restated Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction. If the Company seeks stockholder approval in connection with a Business Combination, the Initial Stockholders (as defined below) agreed to vote their Founder Shares (as defined below in Note 5) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the Initial Stockholders agreed to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Amended and Restated Certificate of Incorporation provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder is acting in concert or as a “group” ​(as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The Sponsor and the Company’s officers and directors (the “Initial Stockholders”) agreed not to propose an amendment to the Amended and Restated Certificate of Incorporation to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Stockholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 24 months from the closing of the Initial Public Offering, or January 8, 2023 (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes, including franchise and income

F-22

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Initial Stockholders agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, with respect to any shares of Class A common stock acquired by the Initial Stockholders in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares of Class A common stock if the Company fails to complete a Business Combination within the Combination Period. The underwriters agreed to waive their rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or business combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or Target that executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) not will it apply to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

As of June 30, 2021, the Company had approximately $1.6 million in cash, and working capital deficit of approximately $48,000 (without taking into account tax obligations of approximately $141,000 that may be paid using investment income earned in the Trust Account).

The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover certain offering costs on behalf of the Company in exchange for issuance of Founders Shares (as defined in Note 4), and loan proceeds from the Sponsor of $150,000 under the Note (Note 4). The Company repaid the Note in full on January 8, 2021. Subsequent to the repayment, the facility was no longer available to us. Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity needs have been satisfied through the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside of the Trust Account.

Based on the foregoing, management believes that the Company will have sufficient working capital and borrowing capacity to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using the funds held outside of the

Trust Account for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

Risks and Uncertainties

Management continues to evaluate the impact of the COVID-19 pandemic on the industry and has concluded that while it is reasonably possible that the virus could have an effect on the Company’s financial position, results of its operations and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The unaudited condensed consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Proposed Business Combination

On May 8, 2021, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Merger Sub and Benson Hill.

Pursuant to the terms of the Merger Agreement, at the closing (the “Closing”) of the transactions contemplated thereby (the “Transactions”), a business combination between the Company and Benson Hill is expected to be effected through the merger of Merger Sub with and into Benson Hill, with Benson Hill surviving as a wholly-owned subsidiary of the Company (the “Merger”). Immediately prior to the effective time of the Merger (the “Effective Time”), each outstanding share of Benson Hill common stock, including common stock held by prior owners of Benson Hill preferred stock (“Existing Benson Hill Common Stock”), will be cancelled and converted into the right to receive a pro rata portion of an aggregate amount of 147,562,680 shares of common stock of the Company, par value $0.0001 per share (“New Benson Hill Common Stock”), (on a fully-diluted basis but subject to adjustment depending on the final allocation of Earn Out Shares and Earn Out Awards (each, as defined below)), consisting of (i) 130,000,000 shares of unrestricted New Benson Hill Common Stock, including the portion of such shares of New Benson Hill Common Stock reserved for issuance upon the future exercise of options (less the Exercise Price Options) and warrants to purchase capital stock of Benson Hill outstanding immediately prior to the merger and converted into options (“Net New Benson Hill Options”) or warrants (“New Benson Hill Warrants”) to purchase New Benson Hill Common Stock and (ii) 17,562,680 restricted shares of New Benson Hill Common Stock that will be held in escrow until, and vest upon, the achievement of certain earn-out thresholds prior to the third anniversary of the closing of the merger (the “Earn Out Shares”), in each case in accordance with the Merger Agreement. In addition to the foregoing, incentive equity awards (“Earn Out Awards”) with a value equivalent to 2,037,320 shares of New Benson Hill Common Stock will be granted under the proposed New Incentive Plan (as defined in the Merger Agreement) to certain holders of Benson Hill Options. The number of Earn Out Shares and Earn Out Awards may be adjusted prior to the closing of the Merger on a one-for-one basis pursuant to the terms and subject to the conditions set forth in the Merger Agreement such that the number of shares of New Benson Hill Common Stock issued as Earn Out Shares or being reserved for or subject to the Earn Out Awards granted shall not exceed 19,600,000 shares of New Benson Hill Common Stock in the aggregate. In addition, a portion of the shares of New Benson Hill Common Stock reserved for issuance under the New Incentive Plan shall be used for Benson Hill options to be assumed under such plan, representing a number of shares of New Benson Hill Common Stock determined at Closing and equal to the Aggregate Exercise Price (as defined in the merger agreement) divided by $10.00 (the “Exercise Price Options”, together with the Net New Benson Hill Options, the “New Benson Hill Options”).

The Merger is expected to close in the third quarter of 2021, following the receipt of the required approval by the Company’s stockholder and the fulfillment of other customary closing conditions.

Support Agreements

In connection and concurrent with the execution of the Merger Agreement, certain holders representing approximately 67% of outstanding Benson Hill preferred stock and Existing Benson Hill Common Stock

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(determined on an as-converted basis) (“Supporting Holders”) entered into support agreements (the “Support Agreements”) with the Company. Under the Support Agreements, the Supporting Holders agreed, among other things, to execute and deliver a written consent (a) adopting the Merger Agreement and the consummation of the transactions contemplated thereby, after the Company’s registration statement on Form S-4 relating to the Merger and containing a proxy statement of the Company is declared effective by the SEC and (b) to effect a conversion of all of the preferred stock of Benson Hill.

Sponsor Support Agreement

In connection and concurrent with the execution of the Merger Agreement, the Sponsor and certain other holders (together with Sponsor, the “Class B Holders”) of the Company’s Class B common stock entered into a support agreement with the Company (the “Sponsor Support Agreement”). Under the Sponsor Support Agreement, among other things, (a) the Class B Holders agreed to vote in favor of the transactions contemplated by the Merger Agreement, (b) Sponsor agreed that following consummation of the Merger, a certain amount of its New Benson Hill Common Stock will be subject to substantially the same terms and restrictions as apply to Earn Out Shares and (c) on behalf of itself and the other Class B Holders, Sponsor has agreed to waive certain of their anti-dilution and conversion rights.

Lock-up Agreements

In connection with the execution of the Merger Agreement, certain Pre-Closing Holders entered into certain lock-up agreements (the “Lock-up Agreements”) with STPC and Benson Hill. Pursuant to the Lock-up Agreements certain holders of Restricted Securities (as defined therein) have agreed, among other things, to be subject to a lock-up period which will last from the Closing until the earlier of (i) the date that is six months after the Closing and (ii) the date after the Closing on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction (the “Lock-up Period”) in respect of their Restricted Securities. During this Lock-up Period, the holders of Restricted Securities may not transfer any Restricted Securities or engage in any short sales or other hedging or derivative transactions, subject to certain limited exceptions.

PIPE Financing

On May 8, 2021, the Company entered into subscription agreements (each, a “Subscription Agreement”) with certain investors (the “PIPE Investors”) pursuant to which, among other things, the PIPE Investors have agreed to subscribe for and purchase, and the Company has agreed to issue and sell to the PIPE Investors, an aggregate of 22,500,000 shares of its Class A common stock, for an aggregate purchase price of $225,000,000 on the date of Closing, on the terms and subject to the conditions set forth therein. The Subscription Agreement contains customary representations and warranties of STPC, on the one hand, and each PIPE Investor, on the other hand, and customary conditions to closing, including the consummation of the transactions contemplated by the Merger Agreement.

Note 2 — Basis of Presentation and Summary of Significant Accounting Policies

Basis of Presentation

The accompanying condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, the condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the balances and results for the periods presented. Operating results for the three and six months ended June 30, 2021 are not necessarily indicative of the results that may be expected through December 31, 2021.

F-25

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The accompanying condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on March 31, 2021.

Principles of Consolidation

The condensed consolidated financial statements of the Company include all of its wholly-owned subsidiaries, which were incorporated in Delaware on March 19, 2021 in connection with the planned merger. All inter-company accounts and transactions are eliminated in consolidation.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

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

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Corporation coverage limit of $250,000, and any cash held in the Trust Account. As of June 30, 2021 and December 31, 2020, the Company had not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

Use of Estimates

The preparation of unaudited condensed consolidated financial statements in conformity with GAAP requires the Company’s management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the unaudited condensed consolidated financial statements, which management considered

F-26

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Investments Held in Trust Account

The Company’s portfolio of investments is comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income on investments held in the Trust Account in the accompanying unaudited condensed statement of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Fair Value of Financial Instruments

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers include:

•

Level 1, defined as observable inputs such as quoted prices for identical instruments in active markets;

•

Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

•

Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

As of June 30, 2021 and December 31, 2020, the carrying values of cash, prepaid expenses, accounts payable, accrued expenses, franchise tax payable and notes payable to related party approximate their fair values due to the short-term nature of the instruments.

Derivative warrant liabilities

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued stock purchase warrants, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” ​(“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is re-assessed at the end of each reporting period.

The warrants issued in connection with the Initial Public Offering (the “Public Warrants”) and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly,

F-27

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s statement of operations. The fair value of the Public Warrants issued in connection with the Initial Public Offering and Private Placement Warrants were initially measured at fair value using the Black-Scholes Option Pricing Method (“BSM”) and subsequently, the fair value of the Private Placement Warrants has been estimated using the BSM each measurement date. The fair value of Public Warrants issued in connection with the Initial Public Offering have subsequently been measured based on the listed market price of such warrants.

Offering Costs Associated with the Initial Public Offering

Offering costs consisted of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with warrant liabilities are expensed as incurred, presented as non-operating expenses in the condensed consolidated statements of operations. Offering costs associated with the Class A common stock were charged to stockholders’ equity upon the completion of the Initial Public Offering. At January 8, 2021, approximately $828,000 was charged to expense in offering costs associated with warrant liabilities.

Class A Common Stock Subject to Possible Redemption

The Company accounts for its Class A common stock subject to possible redemption in accordance with the guidance in ASC 480. Class A common stock subject to mandatory redemption (if any) is classified as liability instruments and are measured at fair value. Conditionally redeemable Class A common stock (including Class A common stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. At all other times, Class A common stock is classified as stockholders’ equity. The Company’s Class A common stock feature certain redemption rights that are considered to be outside of the Company’s control and subject to the occurrence of uncertain future events. Accordingly, as of June 30, 2021, 35,236,895 shares of Class A common stock subject to possible redemption is presented at redemption value as temporary equity, outside of the stockholders’ equity section of the condensed consolidated balance sheets. As of December 31, 2020, there were no shares of Class A common stock subject to possible redemption.

Income Taxes

The Company’s taxable income primarily consists of interest income on the Trust Account. The Company’s general and administrative expenses are generally considered start-up costs and are not currently deductible. For the three and six months ended June 30, 2021, income tax expense for the period was deemed to be immaterial.

The Company follows the asset and liability method of accounting for income taxes under FASB ASC Topic 740 , “Income Taxes” ​(“ASC 740”). Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that included the enactment date. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. As of June 30, 2021, the Company had deferred tax assets of approximately $928,000 with a full valuation allowance against them. Deferred tax assets were deemed immaterial as of December 31, 2020.

ASC 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those

F-28

benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. There were no unrecognized tax benefits as end of quarter June 30, 2021 and December 31, 2020. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. No amounts were accrued for the payment of interest and penalties as end of quarter June 30, 2021. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is subject to income tax examinations by major taxing authorities since inception.

Net Loss Per Share of Common Stock

The Company’s condensed statements of operations include a presentation of net income (loss) per share for Class A common stock subject to possible redemption in a manner similar to the two-class method of net income (loss) per common stock. Net income(loss) per common stock, basic and diluted, for Class A common stock is calculated by dividing the interest income earned on the Trust Account, less interest available to be withdrawn for the payment of taxes, by the weighted average number of Class A common stock outstanding for the periods. Net income (loss) per common stock, basic and diluted, for Class B common stock is calculated by dividing the net income (loss),adjusted for income attributable to Class A common stock, by the weighted average number of Class B Common Stock outstanding for the periods. Class B common stock include the Founder Shares as these common stocks do not have any redemption features and do not participate in the income earned on the Trust Account.

The calculation of diluted net income (loss) per common stock does not consider the effect of the warrants issued in connection with the (i) IPO, (ii) exercise of over-allotment and (iii) Private Placement since the exercise price of the warrants is in excess of the average common stock price for the period and therefore the inclusion of such warrants would be anti-dilutive.

The following table reflects the calculation of basic and diluted net income (loss) per share of common stock:

Recent Accounting Standards

In August 2020, the FASB issued Accounting Standard Update (ASU) No. 2020-06, Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. As permitted by the standard, the Company has elected to early adopt this standard in its first quarter of 2021 with no impact upon adoption.

The Company’s management does not believe that any other recently issued, but not yet effective, accounting standards if currently adopted would have a material effect on the accompanying financial statements.

Note 3 — Initial Public Offering

On January 8, 2021, the Company consummated its Initial Public Offering of 40,250,000 Units, including 5,250,000 Over-Allotment Units, at $10.00 per Unit, generating gross proceeds of $402.5 million, and incurring offering costs of approximately $22.9 million, inclusive of approximately $14.1 million in deferred underwriting commissions.

Each Unit consists of one share of Class A common stock and one-fourth of one Public Warrant. Each whole Public Warrant entitles the holder to purchase one share of Class A common stock at exercise price a price of $11.50 per share, subject to adjustment (see Note 7).

Note 4 — Related Party Transactions

Founder Shares

On October 23, 2020, the Sponsor paid $25,000 on behalf of the Company to cover certain offering costs in exchange for issuance of 10,062,500 Founder Shares. The Initial Stockholders agreed to forfeit up to 1,312,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. The underwriter exercised its over-allotment option in full on January 8, 2021; thus, these 1,312,500 Founder Shares are no longer subject to forfeiture.

The Initial Stockholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination; or (B) subsequent to the initial Business Combination, (x) if the closing price of the Class A common stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, capital stock exchange , reorganization or other similar transaction that results in all of the stockholders having the right to exchange their shares of common stock for cash, securities or other property.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company consummated the Private Placement of 6,553,454 Private Placement Warrants at a price of $2.00 per Private Placement Warrant to the Sponsor, generating proceeds of approximately $13.1 million.

Each whole Private Placement Warrant is exercisable for one whole share of Class A common stock at an exercise price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Warrants to the Sponsor was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the Private Placement Warrants will expire worthless. The Private Placement Warrants will be non-redeemable for cash and exercisable on a cashless basis so long as they are held by the Sponsor or its permitted transferees.

The Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of the initial Business Combination.

Related Party Loans

On October 23, 2020, the Sponsor agreed to loan the Company an aggregate of up to $300,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was non-interest bearing and payable upon the completion of the Initial Public Offering. The Company borrowed $150,000 under the Note and repaid the Note in full on January 8, 2021. Subsequent to the repayment, the facility was no longer available to us.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lenders’ discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $2.00 per warrant. The warrants would be identical to the Private Placement Warrants. As of June 30, 2021 and December 31, 2020, the Company had no borrowings under the Working Capital Loans.

Administrative Services Agreement

The Company entered into an agreement that provided that, commencing on the effective date of the Initial Public Offering through the earlier of consummation of the initial Business Combination and the Company’s liquidation, the Company agreed to pay the Sponsor a total of $10,000 per month for office space, utilities, secretarial support and administrative services.

The Company incurred $30,000 and $60,000 in such fees included as general and administrative expenses to related party on the accompanying unaudited condensed consolidated statement of operations for the three and six months ended June 30, 2021, respectively. As of June 30, 2021, the full amount has been paid.

The Company’s officers or directors will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. The Company’s audit committee will review on a quarterly basis all payments that were made to the Sponsor, officers or directors, or the Company’s or their affiliates. Any such payments prior to an initial Business Combination will be made using funds held outside the Trust Account.

exercise of the Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans) were entitled to registration rights pursuant to a registration rights agreement signed upon the consummation of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a 45-day option from the date of Initial Public Offering to purchase up to 5,250,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. The underwriter exercised its over-allotment option in full on January 8, 2021.

The underwriters were entitled to an underwriting discount of $0.20 per Unit, or approximately $8.1 million in the aggregate, which was paid upon the closing of the Initial Public Offering. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or approximately $14.1 million in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Note 6 — Derivative Warrant Liabilities

As of June 30, 2021, the Company had outstanding 10,062,500 Public Warrants and 6,553,454 Private Placement Warrants. There were no warrants outstanding at December 31, 2020.

Public Warrants may only be exercised for a whole number of shares of Class A common stock. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of a Business Combination or (b) 12 months from the closing of the Initial Public Offering; provided in each case that the Company has an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the Public Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Public Warrants on a cashless basis and such cashless exercise is exempt from registration under the Securities Act). The Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, it will use its commercially reasonable efforts to file with the SEC and have an effective registration statement covering the shares of the Class A common stock issuable upon exercise of the warrants and to maintain a current prospectus relating to those shares of the Class A common stock until the warrants expire or are redeemed. If a registration statement covering the shares of the Class A common stock issuable upon exercise of the warrants is not effective by the 60th business day after the closing of the initial Business Combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act or another exemption.

The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if (x) the Company issues additional shares of the Class A common stock or equity-linked securities for capital raising purposes in connection with the closing of the initial Business Combination at an issue price or effective issue price of less than $9.20 per share of the Class A common stock (with such issue price or effective issue price to be determined in good faith by the board of directors and, (i) in the case of any such issuance to the Sponsor or their affiliates, without taking into account any Founder Shares held by the Initial Stockholders or such affiliates, as applicable, prior to such issuance, and (ii) to the extent that such

issuance is made to the Sponsor or its affiliates, without taking into account the transfer of Founder Shares or Private Placement Warrants (including if such transfer is effectuated as a surrender to the Company and subsequent reissuance by the Company) by the Sponsor in connection with such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the completion of the initial Business Combination (net of redemptions), and (z) the volume-weighted average trading price of the Class A common stock during the 20 trading day period starting on the trading day prior to the day on which the Company completes its initial Business Combination (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $10.00 and $18.00 per share redemption trigger prices described under “Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00” and “Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00” will be adjusted (to the nearest cent) to be equal to 100% and 180% of the higher of the Market Value and the Newly Issued Price, respectively.

The Private Placement Warrants are identical to the Public Warrants, except that the Private Placement Warrants and the shares of Class A common stock issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be non-redeemable so long as they are held by the Sponsor or its permitted transferees. If the Private Placement Warrants are held by someone other than the Sponsor or its permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $18.00:

Once the warrants become exercisable, the Company may redeem the outstanding warrants (except as described herein with respect to the Private Placement Warrants):

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

upon a minimum of 30 days’ prior written notice of redemption; and

•

if, and only if, the last reported sale price (the “closing price”) of Class A common stock equals or exceeds $18.00 per share (as adjusted) for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

The Company will not redeem the warrants as described above unless an effective registration statement under the Securities Act covering the shares of Class A common stock issuable upon exercise of the warrants is effective and a current prospectus relating to those shares of Class A common stock is available throughout the 30-day redemption period. Any such exercise would not be on a “cashless” basis and would require the exercising holder to pay the exercise price for each warrant being exercised.

Redemption of warrants when the price per share of Class A common stock equals or exceeds $10.00:

Commencing ninety days after the warrants become exercisable, the Company may redeem the outstanding warrants:

•

in whole and not in part;

•

at $0.10 per warrant upon a minimum of 30 days’ prior written notice of redemption, provided that holders will be able to exercise their warrants, but only on a cashless basis, prior to redemption and receive that number of shares determined by reference to an agreed table based on the redemption date and the “fair market value” of Class A common stock;

F-33

STAR PEAK CORP II

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

•

if, and only if, the closing price of the Class A common stock equals or exceeds $10.00 per Public Share (as adjusted) for any 20 trading days within the 30-trading day period ending three trading days before the Company sends the notice of redemption to the warrant holders; and

•

if the closing price of the Class A common stock for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders is less than $18.00 per share (as adjusted), the Private Placement Warrants must also be concurrently called for redemption on the same terms as the outstanding Public Warrants, as described above.

The “fair market value” of Class A common stock for the above purpose shall mean the volume weighted average price of Class A common stock during the 10 trading days ending on the third trading day immediately following the date on which the notice of redemption is sent to the holders of warrants. In no event will the warrants be exercisable in connection with this redemption feature for more than 0.361 shares of Class A common stock per warrant (subject to adjustment).

If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

Note 7 — Stockholders’ Equity

Class A Common Stock — The Company is authorized to issue 400,000,000 shares of Class A common stock with a par value of $0.0001 per share. As of June 30, 2021, there were 5,013,105 shares of Class A common stock issued or outstanding, excluding 35,236,895 shares subject to possible redemption. At December 31, 2020, there were no shares of Class A common stock issued and outstanding.

Class B Common Stock — The Company is authorized to issue 40,000,000 shares of Class B common stock with a par value of $0.0001 per share. As of June 30, 2021 and December 31, 2020, there were 10,062,500 shares of Class B common stock issued and outstanding (see Note 4).

Prior to the initial Business Combination, only holders of the Class B common stock will have the right to vote on the election of directors. Holders of the Class A common stock will not be entitled to vote on the election of directors during such time. In addition, prior to the completion of an initial Business Combination, holders of a majority of the Class B common stock may remove a member of the board of directors for any reason. These provisions of the Amended and Restated Certificate of Incorporation may only be amended by a resolution passed by a majority of the shares of Class B common stock. With respect to any other matter submitted to a vote of the stockholders, including any vote in connection with the initial Business Combination, except as required by law or the applicable rules of the New York Stock Exchange then in effect, holders of the Class A common stock and Class B common stock will vote together as a single class, with each share entitling the holder to one vote.

The Class B common stock will automatically convert into Class A common stock at the time of the initial Business Combination on a one-for-one basis, subject to adjustment for stock splits, stock dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional shares of Class A common stock, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of the initial Business Combination, the ratio at which shares of Class B common stock shall convert into shares of Class A common stock will be adjusted (unless the holders of a majority of the outstanding shares of Class B common stock agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of shares of Class A common stock issuable upon conversion of all shares of Class B common stock will equal, in the aggregate, on an as-converted basis, 20% of the sum of the total number of all shares of common stock outstanding upon the completion of the Initial Public Offering plus all shares of Class A

common stock and equity-linked securities issued or deemed issued in connection with the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination). Holders of Founder Shares may also elect to convert their shares of Class B common stock into an equal number of shares of Class A common stock, subject to adjustment as provided above, at any time.

Preferred Stock — The Company is authorized to issue 1,000,000 shares of preferred stock, par value $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of June 30, 2021 and December 31, 2020, there were no shares of preferred stock issued or outstanding.

Transfers to/from Levels 1, 2, and 3 are recognized at the end of the reporting period. The estimated fair value of the Public Warrants transferred from a Level 3 measurement to a Level 1 fair value measurement in March 2021, when the Public Warrants were separately listed and traded.

Level 1 assets include investments in U.S. Treasury securities. The Company uses inputs such as actual trade data, quoted market prices from dealers or brokers, and other similar sources to determine the fair value of its investments.

Level 3 instruments are comprised of derivative warrant liabilities measured at fair value using the BSM. The estimated fair value of the Private Placement Warrants and the Public Warrants is determined using Level 3 inputs. Inherent in the BSM are assumptions related to expected stock-price volatility, expected life, risk-free interest rate and dividend yield. The Company estimates the volatility of its common stock warrants based on implied volatility from the Company’s traded warrants and from historical volatility of select peer company’s common stock that matches the expected remaining life of the warrants. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the warrants. The expected life of the warrants is assumed to be equivalent to their remaining contractual term. The dividend rate is based on the historical rate, which the Company anticipates remaining at zero. Any changes in these assumptions can change the valuation significantly.

The following table provides quantitative information regarding Level 3 fair value measurements inputs as their measurement dates:

​	Initial Fair	March 31,		June 30,
​	Value	2021		2021
Option term (in years)	5 – 5.73	​	5.50	​	5.21

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Benson Hill, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Benson Hill, Inc. and subsidiaries (the Company) as of December 31, 2020 and 2019, the related consolidated statements of operations, comprehensive loss, redeemable convertible preferred stock and stockholders’ deficit, and cash flows for each of the three years in the period ended December 31, 2020, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2020 and 2019, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2020, in conformity with U.S. generally accepted accounting principles.

The Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, the Company has suffered recurring losses from operations and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Adoption of New Accounting Standard

As discussed in Note 2 to the consolidated financial statements, the Company changed its method for accounting for leases in the years ended December 31, 2020, 2019, and 2018 due to the adoption of ASU No. 2016-02, Leases (Topic 842).

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2018.

Benson Hill, Inc. and Subsidiaries
Notes to Consolidated Financial Statements
(Dollar Amounts in Thousands)

1. Description of Business

Benson Hill, Inc. and subsidiaries (collectively, the Company, we, us, or our) was founded in 2012 and incorporated in Delaware. We are an agri-food innovator that combines data science and machine learning with biology and genetics to unlock nature’s genetic diversity in the development of healthier, great-tasting food and ingredients. We are headquartered in St. Louis, Missouri, where the majority of our research and development activities are managed, but supply fresh produce through packing, distribution, and growing locations in the southeastern states of the United States, and process dry peas in North Dakota.

Liquidity and Going Concern

The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), assuming the Company will continue as a going concern. As of December 31, 2020, the Company had cash and cash equivalents of $9,743 and marketable securities of $100,334, term debt and notes payable of $29,810 and an accumulated deficit of $154,322. During the year ended December 31, 2020, the Company incurred a net loss of $67,159, had negative cash flows from operating activities of $52,678, and violated certain financial covenants under its term debt agreement, which were subsequently waived. As a result of these conditions, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are available to be issued.

The Company’s business prospects are subject to risks, expenses, and uncertainties frequently encountered by companies in the early stages of commercial operations. To date, the Company has been funded primarily by equity and debt financings, including the issuance of redeemable convertible preferred stock and term debt, as well as the use of a revolving line of credit, which is subject to renewal in July of 2021. Certain of these debt financings require the Company’s wholly owned subsidiary, Dakota Dry Bean, to comply with financial covenants that will likely require financial support from Benson Hill, the Parent Company, to remain in compliance with the financial covenants during 2021 (see Note 12 — Debt). Further, these same debt financings require the Parent Company to maintain a minimum cash balance. If the Company breaches these covenants, the holder of the debt may declare all amounts immediately due and payable. If the covenants are breached, the Company plans to attempt to secure a waiver of the covenants or an amendment that modifies the covenants but there are no assurances that the Company will be able to comply with its future covenants without such a waiver or that the Company will be successful in obtaining a waiver or an amendment during 2021.

The attainment of profitable operations is also dependent upon future events, including obtaining adequate financing to complete and commercialize the Company’s research and development activities, obtaining adequate grower relationships, building its customer base, successfully executing its business and marketing strategy and hiring appropriate personnel.

Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, maintain existing debt arrangements or secure additional funding may require the Company to modify, delay, or abandon some of its planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on the Company’s business, operating results, financial condition, and ability to achieve its intended business objectives.

Accordingly, in addition to obtaining waivers for any potential debt covenant violations, the Company will need to obtain additional financing. As the issuance of additional equity or debt is not entirely within the Company’s control, management cannot be certain they will be successful in obtaining additional financing on terms acceptable to the Company, or at all.

The consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

F-43

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company prepares its consolidated financial statements in conformity with GAAP.

Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and an Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in its consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Significant management estimates include those with respect to allowance for doubtful accounts, reserves for inventory obsolescence, the recoverability of long-lived assets, intangibles and goodwill, the estimated value of our warrant liability and the fair value of the Company’s Common Stock.

The fair value of the Company’s Common Stock was determined using valuation methodologies in accordance with the framework of the American Institute of Certified Public Accountants Technical Practice Aid, Valuation of Privately-Held Company Equity Securities Issued as Compensation. The Company granted stock options at exercise prices not less than the fair value of its Common Stock, as determined based on a number of objective and subjective factors, including external market conditions affecting the Company’s industry sector and the prices at which the Company sold shares of preferred stock, the superior rights and preferences of securities senior to the Company’s Common Stock at the time, and the likelihood of a public offering or sale of the Company. Significant changes to the key assumptions used in the valuations could result in different fair values of Common Stock and other equity instruments at each valuation date.

Cash and Cash Equivalents

We consider all short-term, highly liquid investments with maturities of 90 days or less at acquisition date to be cash equivalents.

Marketable Securities

We classify our investment securities as available-for-sale on the date of purchase. The securities are recorded at their fair value with the unrealized gains and losses, net of tax effect, recorded in other comprehensive income. Realized gains and losses affect income and the prior fair value adjustments are reclassified within stockholders’ deficit. Premiums and discounts are amortized on the straight-line method. Gains and losses on the sale of securities are determined using the specific-identification method.

Accounts Receivable

Accounts receivable represent amounts owed to us from the sale of harvested produce and grain, soybean meal and oil, royalties, and licensing of proprietary technology. The carrying value of our receivables represent estimated net realizable values. We generally do not require collateral and estimate any required allowance for doubtful accounts based on historical collection trends, the age of outstanding receivables, and existing economic conditions. If events or changes in circumstances indicate that specific receivable balances may be impaired, further consideration is given to the collectability of those balances and the allowance is recorded accordingly.

Past-due receivable balances are written off when the Company’s internal collection efforts have been unsuccessful in collecting the amounts due. The Company had amounts reserved for doubtful accounts at December 31, 2020 and 2019, of $177 and $28, respectively.

F-44

Inventories

Inventories, primarily comprised of fresh produce, dry beans, seeds, soybean meal, soybean oil, barley, and related packaging materials, are recorded at the lower of cost or net realizable value with cost determined on the first-in, first-out basis. Crops under production include the direct costs of land preparation, seed, planting, growing, and maintenance.

We evaluate inventory balances for obsolescence on a regular basis based on the age of the inventory and our sales forecasts. We also determine the net realizable value of our inventory balances using projected selling prices for our products, market prices for the underlying agricultural markets, the age of products, our anticipated costs, and other factors, and compare those prices with the current weighted average costs of our inventories. If our costs are higher than the projected selling prices, a valuation adjustment is recorded.

Certain seed costs associated with products not yet commercialized are expensed to research and development.

Property and Equipment

Property and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful life of the respective assets. Leasehold improvements are depreciated over the shorter of their useful life or remaining term of the lease.

Expenses for repairs and maintenance are expensed as incurred, and upon retirement or sale, the cost and related accumulated depreciation of the disposed assets are removed from the accounts and any resulting gain or loss is recognized on the consolidated statement of operations and comprehensive loss. Depreciation expense has been calculated using the following estimated useful lives:

Furniture and fixtures	5-7 years
Machinery, field and laboratory equipment	5-7 years
Computer equipment	3-5 years
Vehicles	3-7 years
Buildings and building improvements	5-20 years

Long-lived assets are reviewed for impairment whenever, in management’s judgement, conditions indicate a possible loss. Such impairment tests compare estimated undiscounted cash flows with the carrying value of the asset. If an impairment is indicated, the asset is written down to its fair value. The Company did not record any property or equipment impairments for the year ended December 31, 2020 or 2019.

Leases

The Company, at the inception of the contract, determines whether a contract is or contains a lease. For leases with terms greater than 12 months, the Company records the related operating or finance right of use asset and lease liability at the present value of lease payments over the lease term. Renewal options are not included in the measurement of the right of use assets and lease liabilities unless the Company is reasonably certain to exercise the optional renewal periods. Some leases also include early termination options, which can be exercised under specific conditions. Additionally, certain leases contain incentives, such as construction allowances from landlords. These incentives reduce the right-of-use asset related to the lease.

Some of the Company’s leases contain rent escalations over the lease term. The Company recognizes expense for operating leases on a straight-line basis over the lease term. The Company recognizes interest expense and depreciation expense for finance leases. Depreciation expense for assets held under finance leases is computed using the straight-line method over the lease term or useful life for leases that contain a transfer of title or reasonably certain purchase option.

Our lease agreements contain variable lease payments for increases in rental payment as a result of indexation, common area maintenance, utility, and maintenance charges. The Company has elected the practical expedient to combine lease and non-lease components for all asset categories. Therefore, the lease

F-45

payments used to measure the lease liability for these leases include fixed minimum rentals along with fixed non lease component charges. The Company does not have significant residual value guarantees or restrictive covenants in the lease portfolio.

Most of the Company’s leases do not provide a readily available implicit interest rate. Therefore, the Company estimates the incremental borrowing discount rate based on information available at lease commencement. The incremental borrowing rate represents an estimate of the market interest rate the Company would incur at lease commencement to borrow an amount equal to the lease payments on a collateralized basis over the term of a lease.

Goodwill and Intangible Assets

Goodwill, arising from a business combination as the excess of purchase price and related costs over the fair value of identifiable assets acquired and liabilities assumed is not amortized and is subject to an annual impairment test as of December 1, unless events indicate an interim test is required. In performing this impairment test, management will first qualitatively assess indicators of a reporting unit’s fair value. If after completing the qualitative assessment, management believes it is likely that a reporting unit is impaired, a discounted cash flow analysis is prepared to estimate the fair value of the reporting unit.

Critical estimates in the determination of the fair value of each reporting unit include, but are not limited to, future expected cash flows based on estimates of future sales volumes, sales prices, production costs, and discount rates. These estimates generally constitute unobservable Level 3 inputs under the fair value hierarchy. An adjustment to goodwill will be recorded for any goodwill that is determined to be impaired.

Impairment of goodwill is measured as the excess of the carrying amount of goodwill over the fair value of the reporting unit. During the year ended December 31, 2020, the Company evaluated goodwill for impairment using a qualitative assessment for one reporting unit and using a quantitative assessment for two reporting units resulting in a goodwill impairment charge of $4,832. During the years ended December 31, 2019 and 2018, the Company evaluated goodwill for impairment using a qualitative assessment for all reporting units concluding it was not more likely than not that goodwill was impaired.

Intangible assets consist primarily of customer relationships, trade names, employment agreements, technology licenses, and in-process research and development (IPRD). Intangible assets are valued based on the income approach which utilizes discounted cash flows. These estimates generally constitute Level 3 inputs under the fair value hierarchy.

IPRD, consisting of seed germplasm, is considered an indefinite-lived intangible asset until the abandonment or completion of the associated research and development efforts. If abandoned, or our projections regarding the costs to complete the research and future revenues and cash flows require adverse revisions, the assets would be impaired. If the activities are completed, a determination is made regarding the useful lives of such assets and methods of amortization. During the year ended December 31, 2020 and 2019, no IPRD assets were abandoned or completed, and we did not otherwise identify factors of impairment of these assets.

Similar to goodwill, indefinite lived intangible assets are subject to an annual impairment test as of December 1, unless events indicate an interim test is required. During the year ended December 31, 2020 and 2019, the Company evaluated IPRD for impairment using a qualitative assessment and concluded it was not more likely than not that impairment existed.

In conjunction with business acquisitions, we obtain trade names, enter into employment agreements, and gain access to the distribution channels and customer relationships of the acquired companies. Trade names are amortized over their estimated useful life, which is generally ten years. Employment agreements are being amortized over the contractual period, which is two years. Customer relationships are expected to provide economic benefits to the Company over the amortization period of 15 years and are amortized on a straight-line basis. The amortization period of customer relationships represents management’s best estimate of the expected usage or consumption of the economic benefits of the acquired assets, which is based on our historical experience of customer attrition rates.

F-46

Definite lived intangible assets are reviewed for impairment, at the asset group level, whenever, in management’s judgement, impairment indicators are present. At a minimum, we assess all definite lived intangible assets annually for indicators of impairment. When indicators of impairment are presents, such an assessment involves estimating undiscounted cash flows over the remaining useful life of the intangible. If the review indicates that undiscounted cash flows are less than the carrying value of the intangible asset, the asset group is written down to fair value, and any impairment is assigned to the assets in the asset group in accordance with the applicable guidance, and a corresponding impairment is recognized in the consolidated statement of operations and comprehensive loss. The Company did not record any definite lived intangible asset impairments for the year ended December 31, 2020, 2019 or 2018.

Debt Issuance Costs

The Company capitalizes costs incurred in connection with new borrowings, the establishment or enhancement of credit facilities and the issuance of debt securities. These costs are amortized as an adjustment to interest expense over the life of the borrowing or term of the credit facility using the effective interest method. Debt issuance costs related to a recognized liability are presented in the balance sheet as a direct reduction from the carrying amount of that liability. The unamortized balance of deferred financing costs shown as a reduction from the carrying amount of the liability was $553 and $204 at December 31, 2020 and 2019, respectively. Amortization of debt issuance costs was $228, $18 and $0 for the years ended December 31, 2020, 2019 and 2018, respectively.

Preferred Stock Warrant Liability

The Company presents its preferred stock warrants in the consolidated balance sheets at their estimated fair value. The warrants are exercisable at any time by the holders for cash at a purchase price per share equal to the lowest price per share at which we have sold shares of a specific series of our preferred stock or a number of shares of equivalent value as determined by a specified calculation.

The liability associated with these warrants are subject to remeasurement at each balance sheet date until the earlier of the expiration, exercise, or conversion of the convertible preferred stock warrants into preferred or common shares, with changes in fair value recorded as interest expense (income), net in the consolidated statements of operations.

Redeemable Convertible Preferred Stock

The Series A, B, C, C-1, and D redeemable convertible preferred stock, referred collectively as Preferred Stock, have been classified as temporary equity in the consolidated balance sheets due to the contingent redeemable nature of these securities upon a Deemed Liquidation Event as defined by the shareholder agreements.

A Deemed Liquidation Event is generally defined as a merger, or consolidation in which the Company is a party, or a subsidiary of the Company is a party where the Company issues shares of its capital stock, resulting in a loss of control by the current stockholders; a sale or other disposition of substantially all assets of the Company; a sale or exclusive license of substantially all of the Company’s intellectual property; or one or a series of related transactions resulting in a person or group of affiliated persons holding a majority of outstanding voting stock other than transactions approved by the requisite percentage of the holders of Preferred Stock. Triggering events that could result in a Deemed Liquidation Event are not solely within the control of the Company.

Additionally, the Company is obligated to redeem all Preferred Stock upon the occurrence of such Deemed Liquidation Events if the majority, by voting power, of all holders of Preferred Stock and two-thirds of the holders of Series D Preferred Stock request such redemption. The redemption price shall be equal to the liquidation preferences.

The Preferred Stock is not currently redeemable or probable of redemption as of December 31, 2020 and, therefore, is not being accreted to its liquidation preference as the redemption depends on a Deemed Liquidation Event that is not probable of occurrence. The Company continues to monitor circumstances that may cause the Preferred Stock to become probable of becoming redeemable and adjustments to the

F-47

carrying amounts to accrete to the Preferred Stock redemption values will be made only when the shares become probable of becoming redeemable.

The Company accounts for potentially beneficial conversion features under ASC Topic 470-20, Debt with Conversion and Other Options. As such, the Company assesses whether beneficial conversion features exist for the optional conversion rights that do not require bifurcation as derivatives. If the conversion option is in-the-money as of the commitment date, the Preferred Stock contains a beneficial conversion feature. The beneficial conversion feature is recognized as a deemed dividend against the carrying amount of the Preferred Stock. No beneficial conversion element existed at or subsequent to the respective issuance dates of our Preferred Stock. The Company continues to monitor for the issuance of additional shares below the conversion price, which could result in a contingent beneficial conversion feature.

Fair Value

Assets and liabilities recorded at fair value on a recurring basis on the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows

Level 1 — Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

There were no transfers between Level 1, Level 2, or Level 3 of the fair value hierarchy during the periods presented.

Revenue Recognition

The policies described below represent the Company’s policies under ASC 605 and ASC 606 as there were not material changes to the Company’s policies as a result of the adoption with the exception of any changes explicitly outlined.

Product Sales

We recognize revenue on a gross basis for product sales, consisting primarily of harvested produce, processed yellow pea, barley, soybeans, and soybean meal and oil, at the point in time when obligations under the terms of a contract with the customer are satisfied. This generally occurs at the time of transfer of control of the product. In reaching this conclusion, the Company considers several control indicators of the timing of the transfer of control, including significant risks and rewards of ownership, physical possession, and the Company’s right to receive payment. Shipping and handling costs related to contracts with customers for product sales are accounted for as a fulfillment activity and not as a separate performance obligation to customers.

In addition to selling our own farmed produce, we enter into consignment arrangements with produce growers and packers located outside of the U.S. and growers of certain perishable products in the U.S. Within these arrangements, the Company is acting as an agent and earns a stated commission and as such revenue is reported on a net basis representing the commissions earned in the Company’s consolidated statement of operations. For certain of these transactions, the Company is responsible for shipping and handling activities. When that is the case, revenue is recognized for those services as performed.

F-48

Sales, use, value-added, and other excise taxes are excluded from the measurement of the transaction price. We generally do not allow a right of return.

Software as a Service (“SAAS”)

We enter into contractual arrangements, which provide access to our proprietary platform CropOSTM. CropOSTM is designed to facilitate the accessibility and actionability of certain data, machine learning and AI techniques to enable predictive breeding.

Customers have access to this data and functionality, but not access to any of Benson Hill’s propriety patents or other intellectual property (IP). Customers typically pay for this service with an annual subscription and the Company recognizes revenue under SAAS contracts on a straight-line basis over the term of the arrangement.

Research Licenses

We enter into contractual arrangements, which provide customers the right to use our proprietary IP and/or patents under a research license for a specific period of time. Customers receive all IP and “know how” at the start of the contract and may perform all desired research to incorporate Benson Hill’s IP into potential new strains and breeds of germplasm. Contracts provide for up-front payments as well as milestone payments and royalties based on commercial sales involving the licensed technology at some point in the future when, and if, commercialization occurs. These contracts are considered functional licenses and revenue is recorded at the inception of the contract for the amount the customer is contractually obligated to pay and for which collectability is probable.

For the year ended December 31, 2020, 2019 and 2018, commercialization had not occurred nor was probable and therefore no revenue was recognized for these milestones.

For the year ended December 31, 2020 under ASC 606 we recognized $114,113 of revenue as of a point in time and $235 over time.

The Company’s disaggregated revenue is fully disclosed as revenues by reporting segment (See Note 22 — Segment Information for additional information).

Research and Development Expenses

Research and development expenses consist of costs incurred in the discovery, development, and testing of our products. These expenses consist primarily of employee salaries and benefits, fees paid to subcontracted research providers, costs associated with field trials, chemicals and supplies, and other external expenses. Third-party research and development expenses are expensed when the contracted work has been performed or as milestone results are achieved. Reimbursements of research and development costs from governmental or other third-party grants are recognized as a reduction of research and development expense. For the years ended December 31, 2020, 2019 and 2018, the Company received grant reimbursement of $1,016, $1,142 and $0, respectively.

Patents

We expense patent costs, including related legal costs, as incurred. Costs to maintain, in-license, and defend patents are recorded as selling, general and administrative expenses on the statements of operations and comprehensive loss. Costs to write and support the research for filing patents are recorded as research and development expenses on the statements of operations and comprehensive loss.

Stock-Based Compensation

We measure all stock options granted to employees and directors based on the fair value on the date of the grant and recognize compensation expenses of those awards over the requisite service period, which is generally the vesting period of the respective awards.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model. We are a private company and lack company-specific historical and implied volatility

F-49

information; therefore, we estimate our expected stock volatility based on the historical volatility of a publicly traded set of peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded stock price.

The expected term of our stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options.

The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award from a time period approximately equal to the expected term of the award. Expected dividend yield is zero based on the fact that we have never paid cash dividends and do not expect to pay any cash dividends in the foreseeable future.

We classify share-based compensation expense on our consolidated statement of operations and comprehensive loss as research and development and selling, general and administrative expenses as this is consistent with the manner in which the award recipient’s payroll costs are classified.

Income Taxes

Income taxes are accounted for using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial statement basis and tax basis of assets and liabilities and net operating loss and credit carryforwards using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Valuation allowances are established when it is more likely than not that some portion of the deferred tax assets will not be realized.

When uncertain tax positions exist, the Company recognizes the tax benefit of tax positions to the extent that some or all of the benefit will more likely than not be realized. The determination as to whether the tax benefit will more likely than not be realized is based upon the technical merits of the tax position, as well as consideration of the available facts and circumstances. The Company’s policy is to recognize interest and penalties on uncertain tax positions as income tax expense.

Forward Purchase Contracts

We enter into seed and grain production agreements (Forward Purchase Contracts) with seed producers and growers. The seed and grower contracts often require us to pay prices for the seed and grain produced at commodity futures market prices plus a premium. The grower has the option to fix their price with us throughout the term of the agreement. The grower contracts allow for delivery of grain to us at harvest if so specified when the agreement is executed, otherwise delivery occurs on a date that we elect through a specified date of the following year.

We designate all Forward Purchase Contracts as normal purchases and as a result are exempt from derivative accounting.

Significant Concentrations and Credit Risk

Financial instruments that potentially expose us to concentrations of credit risk consist primarily of cash and cash equivalents, marketable securities, accounts receivable, and Forward Purchase Contracts.

We have cash and cash equivalents and marketable securities at accredited financial institutions and, at times, maintain balances in excess of insured limits but believe such credit risk is minimal. Concentrations of credit risk associated with unsecured accounts receivable may vary between years because of the nature of our business.

Our customers primarily consist of businesses operating in the agriculture industry, including retailers that sell our produce, consumer package goods manufacturers that incorporate our ingredients, and institutions that license our cloud-based genomic platform. For the year ended December 31, 2020, one customer generated greater than 10% of consolidated revenue for a total of $15,270. For the year ended December 31, 2019, four customers each generated greater than 10% of consolidated revenue for a total of

F-50

$38,151. For the year ended December 31, 2018, two customers each generated greater than 10% of consolidated revenue for a total of $3,000.

Foreign Currency Translation

The financial statements for our ex-U.S. operations, primarily comprising licensing arrangements and research and development activities in Brazil and Canada, respectively, are translated to U.S. dollars at current exchange rates. For assets and liabilities, the fiscal year-end rate is used. For revenues, expenses, gains, and losses, an approximation of the average rate for the period is used. Unrealized currency adjustments in the consolidated financial statements are accumulated in equity as a component of accumulated other comprehensive loss. Gains and losses resulting from foreign currency transactions are separately reflected on the consolidated statement of comprehensive loss.

Recently Adopted Accounting Guidance

Effective January 1, 2020, the Company adopted the new guidance of ASC 606, Revenue from Contracts with Customers (Topic 606) for all contracts that had not been completed as of the adoption date (the modified retrospective approach). Topic 606 requires the Company to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

The new guidance requires the Company to apply the following steps: (1) identify the contract with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when, or as, the Company satisfies a performance obligation.

Comparative balance sheet and statement of earnings information has not been restated and continues to be reported under the guidance of ASC 605, Revenue Recognition (Topic 605), that was in effect as of December 31, 2019 and in the years ended December 31, 2019 and 2018. The cumulative effect of initially applying the guidance as an adjustment to the opening accumulated deficit balance at January 1, 2020 was a reduction of $519. The adjustment was primarily the result of the timing of revenue recognition under our research license contracts.

The Company elected the following practical expedients upon its adoption of Topic 606: (1) Shipping and handling costs related to contracts with customers for sale of goods are accounted for as a fulfillment activity and are included in cost of sales. Accordingly, amounts billed to customers for such costs are included as a component of revenues; (2) The Company has elected to exclude from the measurement of transaction price all taxes assessed by a governmental authority that are both imposed on, and concurrent with, a specific revenue-producing transaction and collected by the Company from a customer for sales taxes.

Effective January 1, 2020, the Company adopted ASC 842, Leases (Topic 842), which requires lessees to recognize assets and liabilities for all leases. The Company adopted Topic 842 using the modified retrospective transition method with the cumulative effect of the adoption being recorded in the earliest comparative reporting period presented. In addition, the Company elected to apply the package of practical expedients that allows entities to forgo reassessing at the transition date: (1) whether any expired or existing contracts are or contain leases; (2) lease classification for any expired or existing leases; and (3) whether unamortized initial direct costs for existing leases meet the definition of initial direct costs under the new guidance.

The Company did not elect the hindsight practical expedient. The Company also elected to use the practical expedient that allows the combination of lease and non-lease contract components in all of its underlying asset categories.

Upon the adoption of this guidance, the Company recognized operating right-of-use assets and operating lease liabilities of $405 in the consolidated balance sheet as of the date of earliest application. The adoption of this new guidance had no impact on opening retained earnings. The adoption of this new guidance did not have a material impact on the Company’s results of operations, cash flows, liquidity or the Company’s covenant compliance under its existing credit agreement.

F-51

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment (ASU 2017-04). ASU 2017-04 simplifies the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test, which requires a hypothetical purchase price allocation.

The Company adopted ASU 2017-04 on January 1, 2020 with no impact to its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (ASU 2018-13). The primary focus of ASU 2018-13 is to improve the effectiveness of the disclosures for fair value measurements by requiring public entities to disclose certain new information while modifying some existing disclosure requirements. The FASB issued ASU 2018-13 as part of its broader disclosure framework project, which aims to improve the effectiveness of disclosures in the notes to the financial statements by focusing on requirements that clearly communicate the most important information to users of the financial statements. The Company adopted ASU 2018-13 on January 1, 2020 with no impact to its consolidated financial statements.

Recently Issued Accounting Guidance Not Yet Effective

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (ASU 2016-13), which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for fiscal years beginning after December 15, 2022, and earlier adoption is permitted. We are currently evaluating the impact of the pending adoption of ASU 2016-13 on our consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (ASU 2020-04). ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts and hedging relationships that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating our contracts and the optional expedients provided by the new standard.

In August 2020, the FASB issued ASU 2020-06, Debt (ASU 2020-06). ASU 2020-06 reduces the number of accounting models for convertible debt instruments and convertible preferred stock. For convertible instruments with conversion features that are not required to be accounted for as derivatives under ASC 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital, the embedded conversion features no longer are separated from the host contract.

ASU 2020-06 is effective for public business entities that meet the definition of a Securities and Exchange Commission (SEC) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2020-06 will have on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (ASU 2019-12). ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 is effective for public companies for fiscal years beginning after December 15, 2020, and interim periods therein with early adoption permitted. The Company is reviewing the provisions of the standard but does not expect a significant impact to the Company’s financial statements.

3. Business Acquisitions

Acquisition of Dakota Dry Bean

On December 21, 2018, we completed the acquisition of Dakota Dry Bean (DDB) for total cash consideration of $22,711. DDB is a leading processor of pea starch, pea flour, pea protein, and barley with

F-52

processing locations in North Dakota and Minnesota. The acquisition of DDB was accounted for as a business combination, and accordingly, the acquired assets and liabilities were recorded at their estimated fair value, as presented below:

​	Fair Value at December 21, 2018
Assets:	​	​	​
Accounts receivable	​	$	5,672
Inventory	​	​	1,248
Prepaid expenses and other assets	​	​	155
Property and equipment	​	​	15,037
Right-of-use asset	​	​	331
Identified intangible assets	​	​	3,574
Goodwill	​	​	3,193
Total assets acquired	​	​	29,210
Liabilities:	​	​	​
Accounts payable	​	​	2,086
Accrued liabilities	​	​	797
Revolving line of credit	​	​	1,248
Lease liability	​	​	331
Long-term debt	​	​	1,817
Deferred tax liability	​	​	220
Total liabilities assumed	​	​	6,499
Total purchase price	​	$	22,711

Goodwill largely consists of expected growth synergies through the commercialization of our innovative technologies and expansion of distribution channels. Identified intangible assets consist of customer relationships, trade name, and an employee agreement of $2,433, $705, and $436, respectively.

Effective December 21, 2018, results from the operations of DDB have been included on our consolidated statement of operations and comprehensive loss. For the year ended December 31, 2018, $709 of revenue was included in the consolidated statement of operations and comprehensive loss.

The unaudited pro forma impact on operating results, as if the acquisition had been completed as of the beginning of 2018, would have resulted in reported revenues and a net loss of $46,919 and ($18,231), respectively. For purposes of the pro forma disclosures, the pro forma adjustments primarily include $526 of costs attributable to the acquisition. The unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what the results of operations would have been had the Company completed the acquisition on the date assumed, nor is it necessarily indicative of the results of operations that may be expected in future periods.

Acquisition of SGI Genetics, Inc.

On February 7, 2019, we completed the acquisition of certain assets and the assumption of certain liabilities of SGI Genetics, Inc. and Schillinger Genetics, Inc. (collectively, SGI) for total cash consideration of $13,814. The acquisition of SGI was accounted for as a business combination, and accordingly, the acquired assets and liabilities were recorded at their estimated fair value, as presented below:

F-53

​	Fair Value at February 7, 2019
Assets:	​	​	​
Accounts receivable	​	$	247
Inventory	​	​	70
Property and equipment	​	​	785

Lease liability	​	​	33
Deferred revenue	​	​	211
Total liabilities assumed	​	​	1,291
Total purchase price	​	$	13,814

IPRD assets, which consist of seed germplasm, are amortized over the estimated useful life of the assets upon successful completion of the related projects. Completion of the related projects is expected to occur over the next four years. Goodwill largely consists of expected growth synergies through the commercialization of acquired seed germplasm.

Effective February 7, 2019, results from the operations of SGI have been included on our consolidated statement of operations and comprehensive loss. Results prior to the acquisition in 2019 were immaterial to the Company’s consolidated financial results.

Acquisition of J&J Produce, Inc.

On May 31, 2019, the Company completed the acquisition of J&J Produce, Inc. and J&J Southern Farms, Inc. (collectively, J&J) for total cash consideration of $14,258, including a fixed deferred payment of $1,250 that remains outstanding at December 31, 2020, and is recorded within accrued expenses (see Note 21 — Commitments and Contingencies). J&J is a producer and distributor of farmed products, including fruits and vegetables. The acquisition of J&J was accounted for as a business combination, and accordingly, the acquired assets and liabilities were recorded at their estimated fair value, as presented below:

​	Fair Value at May 31, 2019
Assets:	​	​	​
Accounts receivable	​	$	7,827
Inventory	​	​	1,814
Prepaid expenses and other assets	​	​	612

Lease liability	​	​	1,345
Accrued liabilities	​	​	2,562
Total liabilities assumed	​	​	12,201
Total purchase price	​	$	14,258

F-54

Goodwill largely consists of expected growth synergies through the commercialization of the Company’s innovative technologies and expansion of distribution channels. Identified intangible assets consist of customer relationships and trade name of $7,310 and $1,640, respectively.

Effective May 31, 2019, results from the operations of J&J have been included on our consolidated statement of operations and comprehensive loss and incorporated in our Fresh reporting unit. For the year ended December 31, 2019, $28,573 of revenue was included in the consolidated statement of operations and comprehensive loss.

The unaudited pro forma impact on operating results, as if the acquisition had been completed as of the beginning of 2019, would have resulted in reported revenues and a net loss of $109,937 and ($40,786), respectively. For purposes of the pro forma disclosures, the pro forma adjustments primarily include $1,343 of costs attributable to the acquisition and amortization of acquired intangibles of $348. The unaudited pro forma impact on operating results, as if the acquisition had been completed as of the beginning of 2018, would have resulted in reported revenues and a net loss of $70,802 and ($23,928), respectively. The unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what the results of operations would have been had the Company completed the acquisition on the date assumed, nor is it necessarily indicative of the results of operations that may be expected in future periods.

In conjunction with all acquisitions we incurred $4,010 and $526 of acquisition-related costs, including legal and accounting fees, during 2019 and 2018, respectively. These costs were recorded in selling, general, and administrative expenses.

4. Fair Value Measurements

Our financial instruments consist of cash and cash equivalents, accounts payable, accrued liabilities, preferred stock warrant liability and notes payable. At December 31, 2020 and 2019, we had cash equivalents of $9,743 and $2,616, respectively, which consisted of money market funds with maturities of less than three months. At December 31, 2020 and 2019, the carrying values of cash and cash equivalents, accounts payable and accrued liabilities approximated fair value due to their short maturities.

The following tables provide the financial instruments measured at fair value on a recurring basis based on the fair value hierarchy:

The preferred stock warrant liability was valued based on a Monte Carlo simulation that values the warrants using a probability weighted discounted cash flow model. Generally, increases or decreases in the fair value of the underlying convertible preferred stock would result in a directionally similar impact in the fair value measurement of the associated warrant liability.

The following table summarizes the change in the Preferred stock warrant liability categorized as level 3.

​	Year Ended December 31, 2020
Balance, beginning of period	​	$	—
Issuances	​	​	4,580
Change in fair value	​	​	661
Ending balance	​	$	5,241

Fair Value of Long-Term Debt

At December 31, 2020 and 2019, the fair value of the Company’s debt, including amounts classified as current, was $30,510 and $18,528, respectively. Fair values are based upon observed prices in an active market, when available, or from valuation models using market information, which fall into Level 3 in the fair value hierarchy.

5. Investments in Available-for-Sale Securities

The Company has invested in marketable debt securities, primarily investment grade corporate bonds and highly liquid U.S Treasury securities, which are held in the custody of a major financial institution. These securities are classified as available-for-sale and, accordingly, the unrealized gains and losses are recorded through other comprehensive income.

​	December 31, 2020
​	Cost Basis			Gross Unrealized Gains			Gross Unrealized Losses			Fair Value
U.S government and agency securities	​	$	75	​	$	1	​	$	—	​	$	76
Corporate notes and bonds	​	​	100,235	​	​	242	​	​	(219)	​	​	100,258

Corporate notes and bonds	​	​	8,376	​	​	—	​	​	(61)	​	​	8,315
Total Investments	​	$	8,376	​	$	—	​	$	(61)	​	$	8,315

The aggregate fair value of investments with unrealized losses that had been owned for less than a year was $25,923 and $8,315 at December 31, 2020 and 2019, respectively. The Company did not have any unrealized losses on investments owned for more than one year as of December 31, 2020 and 2019, respectively. The Company does not intend to sell these securities before recovery of their amortized cost basis.

Available-for-sale investments outstanding at December 31, 2020, classified as marketable securities in the consolidated balance sheets, have maturity dates ranging from the first quarter of 2021 through the second quarter of 2024. The fair value of marketable securities as of December 31, 2020 with maturities within one year and one to five years is $27,268 and $73,066, respectively. The Company classifies available-for-sale investments as current based on the nature of the investments and their availability to provide cash for use in current operations, if needed.

Depreciation expense was $4,617, $2,949 and $351 for the years ended December 31, 2020, 2019 and 2018, respectively.

8. Leases

The Company leases real estate in the form of laboratory, greenhouse, warehouse, and office facilities. The Company also leases equipment in the form of laboratory equipment, vehicles, and office equipment. Generally, the term for real estate leases ranges from 1 to 11 years at inception of the contract and the term for equipment leases is 4 years at inception of the contract. Most real estate leases include one or more options to renew, with renewal terms that generally can extend the lease term from 1 to 10 years. The leases considered to be financing leases include the office lease for the Company’s headquarters in St. Louis, Missouri, a vehicle lease, and an equipment lease.

Lease costs are included within cost of sales, selling, general and administrative expenses, and research and development on the condensed consolidated statements of income and comprehensive income.

In conjunction with the quantitative goodwill impairment analysis performed during 2020 as part of our annual test, we concluded that the goodwill carrying amount exceeded the fair value at our Dakota Dry Bean and Fresh reporting units.

The impairment at the DDB reporting unit was driven by reduced demand for, and margins on, pet food ingredients as driven by lower sales of grain-free companion animal pet food coupled with higher yellow pea processing capacity resulting in an impairment charge of $2,954. After the impairment charge, the goodwill balance associated with the DDB reporting unit is zero.

The impairment at the Fresh reporting unit was driven by lower sales and earnings primarily resulting from the impact of the COVID-19 global pandemic coupled with a series of negative weather events in late 2020. Although a recovery from these negative events, and a return to profitability is expected over time, the near-term impact of these events and uncertainties on timing of recovery resulted in an impairment charge of $1,878. After the impairment charge, the goodwill balance associated with the Fresh reporting unit is zero.

The impairment charges were based upon estimated discounted cash flows, including estimates of future sales volumes, sales prices, production costs and a risk-adjusted cost of capital. These estimates generally constitute unobservable Level 3 inputs under the fair value hierarchy.

The goodwill balance remaining at December 31, 2020 is attributable to our SGI acquisition and included in our Soy reporting unit.

Term Loan, Equipment Loan and Revolver

In April 2019, our wholly owned subsidiary, DDB entered into a Credit Agreement comprised of a $14,000 aggregate principal amount of floating rate, five-year term loan (DDB Term Loan), a $3,500 floating rate, five-year loan to be used for facility expansion (DDB Equipment Loan), and a $6,000 floating rate revolving credit facility (DDB Revolver), which is renewed annually. Proceeds from the Term Loan along with cash on hand were used to fully repay a term loan assumed in the acquisition of DDB by Benson Hill.

The Credit Agreement is secured by substantially all the real and personal property of DDB and is guaranteed, in part, by Benson Hill, the parent company, to a maximum of $7,000. The Term Loan is payable in equal quarterly installments of $416 plus interest with the remaining balance of $5,972 due in April 2024. The Equipment Loan is payable in equal quarterly installments of $175 plus interest through April 2024.

The interest rate on the Term Loan and Equipment Loan is equal to LIBOR plus 4.0% or 4.16% at December 31, 2020. The interest rate on the Revolver is equal to LIBOR plus 3.5% or 3.66% at December 31, 2020.

Under the Credit Agreement, DDB and the Company must comply with certain financial covenants based on DDB’s operations, including a minimum working capital covenant, a minimum net worth covenant, a funded debt to EBITDA ratio covenant, and a fixed charge coverage ratio covenant.

Benson Hill as guarantor must also comply with a minimum cash covenant. The Credit Agreement also contains various restrictions on our activities, including restrictions on indebtedness, liens, investments, distributions, acquisitions and dispositions, control changes, transactions with affiliates, establishment of bank and brokerage accounts, sale-leaseback transactions, margin stocks, hazardous substances, hedging, and management agreements. During 2019 and 2020, we were in violation of certain financial covenants under the Credit Agreement, which were subsequently waived by the lender.

In the second quarter of 2020, the Revolver maturity date was extended to July 2021 and the Credit Agreement was amended to incorporate updated prospective financial covenants with respect to minimum working capital, minimum net worth, funded debt to EBITDA ratio, and fixed charge coverage ratio. Subsequent to the period end, the Credit Agreement was further amended to clarify the definitions of net worth and EBITDA as used in the calculation of certain financial covenants and to adjust the non-financial covenants. While the Company is currently in compliance with the amended covenants, there is a risk that Benson Hill will not maintain compliance with the covenants, as discussed further in Note 1.

Notes Payable

In January 2020, the Company entered into a financing agreement with an investment firm which included a commitment by the lender to make term loans available to the Company in an amount of up to $35,000 with $20,000 available immediately and a second tranche of $15,000 available after the achievement

F-61

of certain financial conditions including the issuance of additional equity by the Company. Availability under the second tranche expired on December 1, 2020.

In accordance with the loan and security agreement, the Company executed term notes with the lender in February 2020 in the aggregate amount of $20,000 with a term of 51 months payable in interest only, at 12.5% interest in the amount of $208 for the first 15 months and principal and interest payments in the amount of $661 for the remaining 36 months with any remaining amount outstanding due May 2024. The term notes are secured by substantially all of the assets of the Company.

In connection with this lending relationship and the execution of the loan and security agreement, the Company issued warrants to purchase preferred stock to the lender. The fair value of the warrants attributable to the funds loaned to the Company, estimated at $3,332 at issuance, were recorded as debt discount, which is amortized over the life of the term notes using the effective interest method and recorded as interest expense.

The fair value of the warrants attributable to the commitment to fund the second tranche, estimated at $1,248 at issuance, were recorded as a current asset and amortized through the date of commitment expiration using the straight-line method and recorded as interest expense. The option to draw down on the second tranche of $15,000 expired in December 2020 unused.

Under the terms of the loan and security agreement, we must comply with certain affirmative and negative covenants. These covenants are primarily restrictions on our activities, including restrictions on indebtedness, liens, distributions, and significant business changes. During 2020, we were in compliance with the covenants under the loan and security agreement.

Paycheck Protection Program Loans

In April 2020, the Company received loan proceeds in the amount of approximately $5,102 under the Paycheck Protection Program. The program, established as part of the Coronavirus Aid, Relief and Economic Security Act, provides for loans to qualifying businesses for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business.

The Company subsequently repaid the loans in full in October 2020, including $25 of accrued interest.

Debt maturities

The contractual maturities of debt as of December 31, 2020 are as follows:

​	Amount
Year ending December 31:	​	​	​
2021	​	$	5,471
2022	​	​	8,147
2023	​	​	8,975
2024	​	​	10,051
2025	​	​	16
Thereafter	​	​	5
​	​	$	32,665

13. Preferred Stock Warrant Liability

In connection with financing arrangements, in the first quarter 2020, the Company issued 1,076,724 warrants to purchase Series C-1 preferred shares or any subsequent preferred share round of Benson Hill. The warrants are exercisable in the following scenarios and at the following purchase prices: (1) at the warrant holder’s discretion at any time before the expiration date (December 1, 2035) at the stock purchase price of the preferred share round for which the warrant holder is converting into (($3.6837 — Series C-1) or ($4.1416 — Series D)), or (2) upon the earliest to occur of (i) the expiration date, (ii) a change of control, or (iii) IPO, the warrants shall automatically exercise at no cost to the holder.

F-62

Should the Company consummate a bridge financing prior to a change of control or an IPO, the holders of the warrants may surrender their warrants to the Company and receive in exchange all of the same consideration, securities, instruments and rights as if the holder participated in the bridge financing with a loan in an amount equal to the shares issuable upon exercise of the warrants multiplied by the stock purchase price.

14. Income Taxes

No income tax benefit for net operating losses incurred has been recorded due to uncertainty in realizing a benefit from those items. The provision for income taxes for the years ended December 31 consists of the following:

The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and deferred tax liabilities as of December 31 are presented as follows:

​	2020			2019
Deferred tax assets:	​	​	​	​	​	​
Net operating losses and tax credits	​	$	33,535	​	$	22,142

Gross deferred tax liabilities	​	​	(12,361)	​	​	(5,386)
Net deferred tax liability	​	$	—	​	$	—

We provide for a valuation allowance when it is more likely than not that we will not realize a portion of the deferred tax assets. We have established a valuation allowance against our deferred tax assets described above as current evidence does not suggest we will realize enough taxable income of the appropriate character within the carryforward period to allow us to realize these deferred tax benefits.

As of December 31, 2020, and 2019, the Company has a net operating loss carryforward, before tax effect, of $136,870 and $89,255 for federal tax purposes, respectively, and $100,325 and $62,794 for state tax purposes, respectively. If not utilized, these state tax losses will expire beginning in 2027. Beginning in tax year 2018 and forward, the Federal law has changed such that net operating losses generated after December 31, 2017 may be carried forward indefinitely. Accordingly, $28,056 of the federal net operating losses will begin to expire in 2032. However, $108,814 of the federal net operating losses have no expiration. Based on the available positive and negative evidence, management believes it is more likely than not that the net deferred tax assets will not be fully realizable.

As of December 31, 2020, and 2019, the Company also has federal and state research and development tax credit carryforwards of approximately $3,620 and $1,700, respectively, to offset future income taxes, which will expire beginning in December 2034. Net operating losses and tax credits may become subject to an annual limitation in the event of certain cumulative changes in the ownership interest as defined under Sections 382 and 383 in the Internal Revenue Code. This could limit the amount of tax attributes that can be utilized annually to offset future taxable income or tax liabilities.

We are subject to federal income taxes in the United States, Brazil, and Canada, as well as various state and local jurisdictions. Several years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the outcome or the timing of resolution of any uncertain tax position, we do not believe that we need to recognize any liabilities for uncertain tax positions as of December 31, 2020 or 2019. Currently, no federal or state income tax returns are under examination by the respective income tax authorities.

15. Comprehensive Income

The Company’s other comprehensive income (OCI) consists of foreign currency translation adjustments from its Brazil subsidiary, which does not use the U.S. dollar as its functional currency, and unrealized gains and losses on marketable debt securities classified as available for sale.

The following table shows changes in accumulated other comprehensive income (AOCI) by component for 2020 and 2019:

​	Cumulative Foreign Currency Translation			Unrealized Gains/Losses on Marketable Securities			Total

Amounts reclassified from AOCI were reported within other, net on the consolidated statement of operations.

16. Loss Per Common Share

The Company computes basic net income (loss) per share using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities may consist of convertible preferred stock, stock warrants, and stock options. The dilutive effect of outstanding preferred stock, stock warrants, and stock options are reflected in diluted earnings per share by application of the treasury stock method. The weighted average share impact of preferred stock, stock warrants, and stock options that were excluded from the calculation of diluted shares due to the Company incurring a net loss for the twelve months ending December 31, 2020, 2019 and 2018 were 79,798, 64,376 and 44,615 shares, respectively.

The following table provides the basis for basic and diluted EPS by reconciling the numerators and denominators of the computations:

​	Year Ended December 31
​	2020		2019		2018
Weighted average shares outstanding:	​	​	​	​	​	​

17. Share-Based Compensation

On June 12, 2012, the shareholders approved the 2012 Stock Incentive Plan (the Plan), which has been subsequently amended. The Plan provides for the issuance of up to 12,304,336 equity-based awards in the form of restricted common stock or stock options awards to eligible employees, directors, and consultants.

Terms of the equity awards, including the vesting requirements are determined by the Board of Director, subject to the provisions of the Plan. Stock options granted by the Company typically vest over

F-65

one year for board members and four years for all other grants with a contractual life of ten years. The exercise price of an incentive stock option shall be not less than 100% of the fair market value of such shares on the date of grant.

Key assumptions used in this pricing model on the date of grant for options granted to employees and nonemployees are as follows:

​	Year Ended December 31,
​	2020			2019
Expected dividend yield	​	​	0%	​	​	0%
Expected volatility	​	​	58%	​	​	52%
Risk-free interest rate	​	​	1.0%	​	​	1.9%
Expected term in years	6.2 years			6.3 years
Weighted average grant date fair value	​	$	0.81	​	$	0.73

The Company recognized $1,010, $644 and $213 of compensation expense related to grants during the years ended December 31, 2020, 2019 and 2018, respectively.

The following is a summary of stock option information and weighted average exercise prices under the Company’s stock incentive plan:

​	Options Outstanding		Weighted Average Exercise Price per Share
Balance at December 31, 2019	​	6,992,291	​	$	0.97
Granted	​	926,000	​	​	1.45
Exercised	​	(337,076)	​	​	0.23
Forfeited	​	(424,750)	​	​	1.21
Expired	​	(56,975)	​	​	1.15
Balance at December 31, 2020	​	7,099,490	​	$	1.05

The following is a summary of stock option information and weighted average grant date fair values under the Company’s stock incentive plan:

​	Options Outstanding		Weighted Average Grant Date Fair Value
Nonvested at December 31, 2019	​	4,551,250	​	$	1.11
Granted	​	926,000	​	​	1.45
Vested	​	(1,527,775)	​	​	0.98
Forfeited	​	(481,725)	​	​	1.20
Nonvested Balance at December 31, 2020	​	3,467,750	​	$	1.25

As of December 31, 2020, 3,631,740 stock options were exercisable at a weighted average remaining contractual life of 7.1 years and a weighted average exercise price of $0.86 per share.

In May 2019, with a subsequent closing in July 2019, we issued a total of 8,861,519 shares of Series C-1 Preferred Stock at $3.6837 per share for proceeds of $32,561, net of issuance costs of $82. In July 2020, with subsequent closings in September 2020, October 2020, and December 2020, we issued a total of 38,412,268 shares of Series D Preferred Stock at $4.1416 per share for proceeds of $154,420, net of issuance costs of $4,668. Also, in December 2020, the Company repurchased 1,542,600 shares of Series A redeemable convertible preferred stock and 403,939 shares of Series B convertible preferred stock for $7,767.

Redeemable Convertible Preferred Stock, net of offering costs outstanding at December 31, consists of the following:

​	2020					2019
​	Shares		Amount			Shares		Amount
Series A preferred stock	​	12,876,927	​	$	9,595	​	14,419,527	​	​	10,759

Series D preferred stock	​	38,412,268	​	​	154,420	​	—	​	​	—
Total redeemable convertible preferred stock	​	102,898,561	​	$	287,323	​	66,432,832	​	$	134,567

The rights, preferences, and privileges of the Preferred Stock are as follows (all capitalized terms are as defined in our July 31, 2020, Amended and Restated Certificate of Incorporation):

Dividends: The Company shall not declare, pay, or set aside any dividends on shares of any class or series of capital stock of the Company unless the holders of Preferred Stock then outstanding first receive, or simultaneously receive, a dividend on each outstanding share of Preferred Stock. No dividends have been declared or paid by us since inception.

Liquidation: In the event of any voluntary or involuntary liquidation, dissolution, or winding up of the Company or Deemed Liquidation Event, the holders of Preferred Stock then outstanding are entitled to be paid, out of the available assets, and prior and in preference to any payment of any available assets to the holders of Common Stock, an amount per share equal to the sum of each respective original series issue price, plus an amount equal to all declared but unpaid dividends thereon.

If upon any such Liquidation of the Company or Deemed Liquidation Event, the Available Assets are insufficient to pay the holders of Preferred Stock the full amount to which they are entitled, the Available Assets will be distributed first to the holders of Series D Preferred Stock, pro rata, in proportion to the full preferential amount each such holder is otherwise entitled to receive, until such holders have received the full amount to which they are entitled; and next, after the full amount to be distributed to Series D Preferred Stock holders has been so distributed, to the holders of Series A Preferred Stock, Series B Preferred Stock, Series C Preferred Stock, and Series C-1 pro rata, and on an equal priority, pari passu basis, in proportion to the full preferential amount each such holder is otherwise entitled to receive. Available Assets means the funds and assets that may be legally distributed to the stockholders of the Company. The remaining Available Assets shall be distributed among the holders of Common Stock pro rata according to the number of shares held by each such holder.

Conversion: The holders of shares of Preferred Stock have conversion rights into an equal number of shares of Common Stock that are subject to adjustment, as defined, in certain instances where the Company issues additional shares of Common Stock. The holders of the Preferred Stock also have down-round protection provision that reduces the conversion price if the Company issues shares at less than the conversion price or for no consideration. As such, if this provision is triggered, it could result in the conversion option becoming more beneficial if such adjustment causes the applicable conversion price to decline below the

F-67

commitment date fair value of the Common Stock. If this occurs, a contingent beneficial conversion feature will be recognized at the date of such adjustment.

Voting Rights: Each holder of outstanding shares of Preferred Stock is entitled to voting rights equal to the number of whole shares of Common Stock into which the shares are convertible as of the record date or date of vote. Each holder of outstanding shares of Common Stock is likewise entitled to voting rights equal to the number of whole shares owned but is precluded from voting on any amendment to the July 31, 2020, Amended and Restated Certificate of Incorporation of the Company that relates solely to the terms of one or more outstanding series of Preferred Stock. The holders of Preferred Stock, voting as a single class and collectively as Preferred Shareholders, are entitled to elect five directors to the Company’s Board of Directors. Two additional directors are elected by mutual consent of the holders of a majority of the Preferred Stock and Common Stock, voting together as a single class on an as-converted to Common Stock basis.

19. Common Stock

The voting, dividend, and liquidation rights of the holders of Common Stock are subject to and qualified by the rights, powers, and preferences of the holders of Preferred Stock. The Common Stock has the following characteristics:

Voting: The holders of Common Stock are entitled to one vote for each share of Common Stock held at all meetings of stockholders and written actions in lieu of meetings. The holders of Common Stock, exclusively and as a separate class, are entitled to elect two directors to the Company’s Board of Directors. Two additional directors are elected by mutual consent of the holders of a majority of the Preferred Stock and Common Stock, voting together as a single class on an as-converted to Common Stock basis.

Dividends: The holders of Common Stock are entitled to receive dividends, if and when declared by the Board of Directors. The Company may not declare or pay any cash dividends to the holders of Common Stock unless, in addition to obtaining any necessary consents, dividends are paid on each series of Preferred Stock in accordance with their respective terms. No dividends have been declared or paid in the year ended December 31, 2020.

Liquidation: In the event of any voluntary or involuntary liquidation, dissolution, or winding-up of the Company, the holders of Common Stock are entitled to share ratably with the holders of Preferred Stock in the Company’s assets available for distribution to stockholders after payment to the holders of Preferred Stock of their liquidation preferences have been satisfied.

20. Employee Benefit Plans

We sponsor two qualified plans under Section 401(k) of the Internal Revenue Code along with a simple individual retirement account retirement plan. All employees who meet certain tenure requirements are eligible to participate in one of these plans but not more than one. Under each plan, employees may elect to defer a portion of pretax or post-tax annual compensation, subject to Internal Revenue Service limits, that are matched by the Company at rates ranging from 3% to 5% of qualifying compensation, depending on the plan. During 2020, 2019 and 2018, the Company made contributions to these plans and recognized expense in the amount of $912, $368 and $184, respectively.

21. Commitments and Contingencies

Litigation

The Company accrues for cost related to contingencies when a loss is probable, and the amount is reasonably determinable. Disclosure of contingencies is included in the financial statements when it is at least reasonably possible that a material loss or an additional material loss in excess of amounts already accrued may be incurred.

The Company is the defendant in a lawsuit filed by J&J Produce Holdings, Inc. related to the acquisition of J&J in May 2019, whereby the plaintiff seeks deferred purchase price payments in Chancery court in Delaware. We have raised various counterclaims, including breach of contract and breach of representations and warranties. The Company believes it has meritorious defenses and intends to defend itself vigorously while also seeking indemnity under an insurance policy related to this transaction, where no amicable resolution can be achieved. Subsequent to year-end, these litigation matters were resolved.

Our subsidiary Benson Hill Seeds, Inc. is the defendant involved in two disputes related to the acquisition of Schillinger Genetics, Inc. The first dispute relates to the termination of John Schillinger and alleges breach of obligations under the employment agreement with Mr. Schillinger and is currently in arbitration. The second dispute involves the release of escrow funds related to the acquisition. We have raised various counterclaims, including breach of the employment Agreement by Mr. Schillinger and breach of representations and warranties. Subsequent to year-end, these litigation matters were resolved.

For all litigation matters noted above, and as of December 31, 2020 and 2019, the Company accrued $2,675 and $1,250, respectively, representing the final settlement amount.

Other Commitments

As of December 31, 2020, we have committed to purchase from seed producers and growers at dates throughout 2021 and 2022 aggregating to $26.1 million based on current commodity futures market prices, other payments to growers and estimated yields per acre. This amount is not recorded in the consolidated financial statements because we have not taken delivery of the grain or seed as of December 31, 2020 and as the grain and seed is subject to specified quality standards prior to delivery.

22. Segment Information

The Company’s reportable business segments reflect the manner in which its chief operating decision maker (CODM) allocates resources and assesses performance, which is at the operating segment level. The Fresh reportable segment is a grower, packer and distributor of year-round fresh produce located in the southeastern United States. The Ingredients reportable segment delivers healthy food ingredients derived from soybean seeds, meal and oil and processed yellow peas. Financial results associated with licensing arrangements that are not allocated to the Fresh or Ingredients reportable segment and costs associated with centralized operations are reported as Unallocated and other. Centralized operations represent corporate and headquarter-related expenses, which include legal, finance, human resources, and other research and development and administrative expenses that are not allocated to individual reporting operating segments.

Our CODM reviews segment performance and allocates resources based upon segment revenue and Adjusted EBITDA. The Company defines Adjusted EBITDA as earnings from continuing operations

F-69

excluding income taxes, interest, depreciation, amortization, stock-based compensation, and the impact of significant non-recurring items.

All segment revenue is earned in the United States and there are no intersegment revenues. Operating segment results for the years ended December 31, 2020, 2019 and 2018 are presented below.

Year Ended December 31, 2020	Revenue			Adjusted EBITDA

As the CODM does not evaluate the operating segments nor make decisions regarding the operating segments based on total assets, we have excluded this disclosure.

23. Subsequent Events

We consider events or transactions that occur after the balance sheet date but prior to the date the financial statements are available to be issued for potential recognition or disclosure in the financial statements. The Company has completed an evaluation of all subsequent events after the audited balance sheet date of December 31, 2020 through May 10, 2021, the date the accompanying financial statements were available to be issued, to ensure that these financial statements include appropriate disclosure of events both recognized in the financial statements as of December 31, 2020, and events that occurred subsequently but were not recognized in the financial statements.

No additional subsequent events requiring disclosure were identified with the exception of items disclosed in Note 12 and Note 21, and those disclosed below.

On May 8, 2021, Benson Hill entered into an Agreement and Plan of Merger (the Merger Agreement) with Star Peak Corp II (STPC). Pursuant to the terms of the Merger Agreement, a business combination between STPC and Benson Hill will be effected through the merger of STPC II Merger Sub Corp (the Merger Sub) with and into Benson Hill, with Benson Hill surviving as a wholly owned subsidiary of STPC (the Merger). Upon the completion of the Merger, owners of Benson Hill common stock and owners of Redeemable Convertible Preferred Stock will exchange their interests in Benson Hill for shares of common stock of the combined entity. In addition, Benson Hill’s existing equity incentive plan will be terminated; awards issued under Benson Hill’s existing equity incentive plan will be exchanged for awards issued under a new equity incentive plan to be adopted by the combined entity. Lastly, immediately after the completion of the Merger, certain investors have agreed to subscribe for and purchase an aggregate of $225,000 of common stock of the combined entity. As a condition precedent to the Merger, the Company must extinguish all outstanding debt which will trigger a prepayment penalty estimated at $3,700.

The combined entity will continue to operate under the Benson Hill management team, led by chief executive officer Matt Crisp. The boards of directors of both STPC and Benson Hill have approved the proposed Merger. Completion of the Merger, which is expected in the third quarter of 2021, is subject to approval of STPC’s shareholders

1. Description of Business

Benson Hill, Inc. and subsidiaries (collectively, the “Company”, “we”, “us”, or “our”) was founded in 2012 and incorporated in Delaware. We are a values-driven food technology company with a vision to build a healthier and happier world by unlocking nature’s genetic diversity with our food innovation engine. Our purpose is to catalyze and broadly empower innovation from plant to plate so great tasting, healthy, affordable, and sustainable food choices are available to everyone. We combine cutting-edge technology with an innovative business approach to bring product innovations to customers and consumers. Our CropOS® technology platform uniquely combines data science, plant science, and food science to create innovative food, ingredient, and feed products — starting with a better seed. We are headquartered in St. Louis, Missouri, where the majority of our research and development activities are managed, but supply fresh produce through packing, distribution, and growing locations in the southeastern states of the United States, and process dry peas in North Dakota.

Liquidity and Going Concern

The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”), assuming the Company will continue as a going concern. As of June 30, 2021, the Company had cash and cash equivalents of $12,992 and marketable securities of $29,634, term debt and notes payable of $28,863, an outstanding revolver balance of $2,970, and an accumulated deficit of $204,089. For the three and six months ended June 30, 2021, the Company incurred a net loss of $27,419 and $49,766, respectively. For the six months ended June 30, 2021, the Company had negative cash flows from operating activities of $47,257 and capital expenditures of $21,128. As a result of these conditions, there is substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the financial statements are available to be issued.

The Company’s business prospects are subject to risks, expenses, and uncertainties frequently encountered by companies in the early stages of commercial operations. To date, the Company has been funded primarily by equity and debt financings, including the issuance of redeemable convertible preferred stock and term debt, as well as the use of a revolving line of credit, which was extended to September of 2021. Certain of these debt financings require the Company’s wholly owned subsidiary, Dakota Dry Bean (“DDB”, “Dakota Ingredients”, or “DI”), to comply with financial covenants that will likely require financial support from Benson Hill, the Parent Company, to remain in compliance with the financial covenants in 2021 and 2022 (see Note 11 — Debt). Further, these same debt financings require the Parent Company to maintain a minimum cash balance. If the Company breaches these covenants, the holder of the debt may declare all amounts immediately due and payable.

If the covenants are breached, the Company plans to attempt to secure a waiver of the covenants or an amendment that modifies the covenants but there are no assurances that the Company will be able to comply with its future covenants without such a waiver or that the Company will be successful in obtaining a waiver or an amendment during 2021.

The attainment of profitable operations is also dependent upon future events, including obtaining adequate financing to complete and commercialize the Company’s research and development activities, obtaining adequate grower relationships, building its customer base, successfully executing its business and marketing strategy, and hiring appropriate personnel.

On May 8, 2021, Benson Hill entered into a definitive business combination agreement between it and Star Peak Corp II (“Star Peak” or “STPC”). As a result of the proposed business combination, if successfully closed, Benson Hill will become a wholly owned subsidiary of Star Peak. Together with Star Peak’s cash resources, additional funding for the Company’s operations would be provided through a Private Investment in Public Equity (“PIPE”) offering to be completed concurrently with the merger. The completion of the

1. Description of Business (continued)

merger would provide the Company a significant infusion of capital. See Note 3 — Merger with Star Peak Corp II for further information regarding the business combination.

In the event the business combination does not close, the Company may be required to obtain additional funding whether through future collaboration agreements, private or public equity offerings, debt issuances, or a combination thereof and such additional funding may not be available on terms the Company finds acceptable or favorable. There is inherent uncertainty associated with these fundraising activities and they are not considered probable.

Failure to generate sufficient revenues, achieve planned gross margins and operating profitability, control operating costs, maintain existing debt arrangements or secure additional funding may require the Company to modify, delay, or abandon some of its planned future expansion or development, or to otherwise enact operating cost reductions available to management, which could have a material adverse effect on the Company’s business, operating results, financial condition, and ability to achieve its intended business objectives. In addition to obtaining waivers for any potential debt covenant violations, the Company will need to obtain additional financing.

As the issuance of additional equity or debt is not entirely within the Company’s control, management cannot be certain they will be successful in obtaining additional financing on terms acceptable to the Company, or at all.

The accompanying unaudited condensed consolidated financial statements do not include any adjustments to reflect the possible future effects on the recoverability and classification of assets or the amounts and classification of liabilities that may result from the outcome of this uncertainty.

2. Summary of Significant Accounting Policies

Basis of Presentation and Principles of Consolidation

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and our wholly owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP for interim financial reporting and Securities and Exchange Commission regulations. In the opinion of management, all adjustments considered necessary for a fair presentation have been included. Results of operations for the interim periods are not necessarily indicative of the results to be expected for the full year ended December 31, 2021. A description of the Company’s significant accounting policies is included in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2020. These unaudited condensed consolidated financial statements should be read in conjunction with the December 31, 2020 audited consolidated financial statements and the notes thereto.

Any reference in these notes to applicable guidance is meant to refer to the authoritative U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and an Accounting Standards Update (“ASU”) of the Financial Accounting Standards Board (“FASB”).

Recently Adopted Accounting Guidance

In December 2019, the FASB issued ASU 2019-12, Income Taxes (“ASU 2019-12”). ASU 2019-12 eliminates certain exceptions related to the approach for intraperiod tax allocation, the methodology for calculating income taxes in an interim period and the recognition of deferred tax liabilities for outside basis differences. ASU 2019-12 is effective for public companies for fiscal years beginning after December 15,

2. Summary of Significant Accounting Policies (continued)

2020, and interim periods therein with early adoption permitted. The Company adopted this ASU in the first quarter of 2021 with no impact to the Company’s financial statements.

Recently Issued Accounting Guidance Not Yet Effective

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (“ASU 2016-13”), which requires measurement and recognition of expected credit losses for financial assets held. ASU 2016-13 is effective for interim and annual reporting periods beginning after December 15, 2022, and earlier adoption is permitted. We are currently evaluating the impact of the pending adoption of ASU 2016-13 on our condensed consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (“ASU 2020-04”). ASU 2020-04 provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. ASU 2020-04 applies only to contracts and hedging relationships that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued due to reference rate reform. These amendments are effective immediately and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. We are currently evaluating our contracts and the optional expedients provided by the new standard.

In August 2020, the FASB issued ASU 2020-06, Debt (“ASU 2020-06”). ASU 2020-06 reduces the number of accounting models for convertible debt instruments and convertible preferred stock. For convertible instruments with conversion features that are not required to be accounted for as derivatives under ASC 815, Derivatives and Hedging, or that do not result in substantial premiums accounted for as paid-in capital, the embedded conversion features no longer are separated from the host contract. ASU 2020-06 is effective for public business entities that meet the definition of a Securities and Exchange Commission (“SEC”) filer, excluding entities eligible to be smaller reporting companies as defined by the SEC, for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company is currently evaluating the impact ASU 2020-06 will have on its condensed consolidated financial statements.

3. Merger with Star Peak Corp II

On May 8, 2021, Benson Hill entered into a definitive business combination agreement between it and Star Peak Corp II. Upon the completion of the proposed business combination transaction, the shareholders of Benson Hill, including common stock on an as-converted basis from owners of Redeemable Convertible Preferred Stock and the Preferred Stock Warrant will exchange their interests in Benson Hill for shares of common stock of the Combined Entity. In addition, Benson Hill’s existing equity incentive plan will be terminated; awards issued under Benson Hill’s existing equity incentive plan will be exchanged for awards issued under a new equity incentive plan to be adopted by the Combined Entity. Lastly, immediately after the completion of the Business Combination, certain investors have agreed to subscribe for and purchase an aggregate of $225 million of common stock of the Combined Entity. The combined company will continue to operate under the Benson Hill management team, led by chief executive officer Matt Crisp. The boards of directors of both Star Peak and Benson Hill have approved the proposed transaction. Completion of the transaction, which is expected in the third quarter of 2021, is subject to approval of Star Peak Corp II’s shareholders.

4. Fair Value Measurements

Assets and liabilities recorded at fair value on a recurring basis on the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows

Level 1 — Observable inputs such as unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active.

Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

Our financial instruments consist of cash and cash equivalents, marketable securities, accounts receivable, accounts payable, accrued liabilities, commodity derivatives, preferred stock warrant liability and notes payable. At June 30, 2021 and December 31, 2020, we had cash and cash equivalents of $12,992 and $9,743, respectively, which consisted of money market funds with maturities of less than three months. At June 30, 2021 and December 31, 2020, the carrying values of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities approximated fair value due to their short maturities.

The following tables provide the financial instruments measured at fair value on a recurring basis based on the fair value hierarchy:

There were no transfers of financial assets or liabilities into or out of Level 1, Level 2, or Level 3 for 2021 or 2020.

All of the Company’s derivative contracts are centrally cleared and therefore are cash-settled on a daily basis. This results in the derivative contracts having a fair value that approximates zero on a daily basis. Therefore, there are no derivative assets or liabilities included in the table above. Refer to Note 6 for further discussion.

4. Fair Value Measurements (continued)

The preferred stock warrant liability was valued based on a Monte Carlo simulation that values the warrants using a probability weighted discounted cash flow model. Generally, increases or decreases in the fair value of the underlying convertible preferred stock would result in a directionally similar impact in the fair value measurement of the associated warrant liability.

The following table summarizes the change in the Preferred stock warrant liability categorized as level 3 for the three and six months ended June 30, 2021 and 2020.

​	Three Months Ended June 30, 2021			Six Months Ended June 30, 2021
Balance, beginning of period	​	$	6,257	​	$	5,241
Change in fair value	​	​	1,703	​	​	2,719

Fair Value of Long-Term Debt

At June 30, 2021 and December 31, 2020, the fair value of the Company’s debt, including amounts classified as current, was $29,459 and $30,510, respectively. Fair values are based upon observed prices in an active market, when available, or from valuation models using market information, which fall into Level 3 in the fair value hierarchy.

5. Investments in Available-for-Sale Securities

The Company has invested in marketable debt securities, primarily investment grade corporate bonds and highly liquid U.S Treasury securities, which are held in the custody of a major financial institution. These securities are classified as available-for-sale and, accordingly, the unrealized gains and losses are recorded through other comprehensive income.

​	June 30, 2021
​	Cost Basis			Gross Unrealized Gains			Gross Unrealized Losses			Fair Value
U.S government and agency securities	​	$	11,101	​	$	62	​	$	—	​	$	11,163
Corporate notes and bonds	​	​	18,474	​	​	114	​	​	(117)	​	​	18,471

​	Cost Basis			Gross Unrealized Gains			Gross Unrealized Losses			Fair Value

Corporate notes and bonds	​	​	100,235	​	​	242	​	​	(219)	​	​	100,258
Total Investments	​	$	100,310	​	$	243	​	$	(219)	​	$	100,334

The aggregate fair value of investments with unrealized losses that had been owned for less than a year was $6,304 and $25,923 at June 30, 2021 and December 31, 2020, respectively. The Company did not have any unrealized losses on investments owned for more than one year as of June 30, 2021 and December 31, 2020, respectively. The unrealized losses in the Company’s portfolio at June 30, 2021 are the result of normal market fluctuations. The Company does not intend to sell these securities before recovery of their amortized cost basis.

Available-for-sale investments outstanding at June 30, 2021, classified as marketable securities in the accompanying condensed consolidated balance sheets, have maturity dates ranging from the third quarter of 2021 through the fourth quarter of 2027. The fair value of marketable securities as of June 30, 2021 with maturities within one year, one to five years, and more than five years was $20,859, $7,446 and $1,329, respectively. The Company classifies available-for-sale investments as current based on the nature of the investments and their availability to provide cash for use in current operations, if needed.

6. Derivatives

Corporate Risk Management Activities

The Company uses exchange-traded futures to manage price risk of fluctuating Chicago Board of Trade (“CBOT”) prices related to forecasted purchases and sales of soybean and soybean related products in the normal course of business. These risk management activities are actively monitored for compliance with the Company’s risk management policies.

As of June 30, 2021, the Company held financial futures related to a portion of its forecasted purchases of soybeans for an aggregate notional volume of 800,000 bushels of soybeans. 35,000 bushels of the aggregate notional volume will settle in 2021 with the remaining 765,000 settling in Q1 2022.

Tabular Derivatives Disclosures

The Company has master netting agreements with its counterparties which allow for the settlement of contracts in an asset position with contracts in a liability position in the event of default or termination. Such netting arrangements reduce the Company’s credit exposure related to these counterparties. As all of the Company’s derivative contracts are centrally cleared and therefore are cash-settled on a daily basis the fair value approximates zero.

The Company’s derivative contracts as of June 30, 2021 were as follows:

​	Asset Derivative			Liability Derivative
Soybeans	​	$	—	​	$	483
Effect of daily cash settlement	​	​	—	​	​	(483)
Net derivatives as classified in the balance sheet	​	$	—	​	$	—

6. Derivatives (continued)

The Company had a current asset representing excess cash collateral posted to a margin account of $442 at June 30, 2021. These amounts are not included with the derivatives presented in the table above and are included in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheets.

Currently, the Company does not seek cash flow hedge accounting treatment for its derivative financial instruments and thus changes in fair value are reflected in current earnings.

The tables below show the amounts of pre-tax gains and losses related to the Company’s derivatives

​	Three Months Ended June 30, 2021
​	(Loss) gain realized on derivatives			Unrealized gain (loss) on derivatives			Total (loss) gain recognized in income
Soybeans	​	$	(523)	​	$	260	​	$	(263)
Oil	​	​	628	​	​	(312)	​	​	316
Total	​	$	105	​	$	(52)	​	$	53

​	Six Months Ended June 30, 2021

Oil	​	​	856	​	​	—	​	​	856

The Company’s soybean positions are designed to hedge risk related to inventory purchases therefore the gains and losses on soybean instruments are recorded in cost of sales in the accompanying condensed consolidated statements of operations. The Company’s oil positions are designed to hedge risk related to sales transactions therefore the gains and losses on oil instruments are recorded in revenues in the accompanying condensed consolidated statements of operations.

The Company classifies the cash effects of its derivatives within the “Cash Flows From Operating Activities” section of the condensed consolidated statements of cash flows.

The Company did not commence trading until January 2021, therefore there was no derivative activity or balances as of December 31, 2020 or for the three and six months ended June 30, 2020.

Term Loan, Equipment Loan and Revolver

In April 2019, our wholly owned subsidiary, DDB entered into a credit agreement comprised of a $14,000 aggregate principal amount of floating rate, five-year term loan (“DDB Term Loan”), a $3,500 floating rate, five-year loan to be used for facility expansion (“DDB Equipment Loan”), and a $6,000 floating rate revolving credit facility (“DDB Revolver”), which is renewed annually (together the “Credit Agreement”). Proceeds from the DDB Term Loan along with cash on hand were used to fully repay a term loan assumed in the acquisition of DDB by Benson Hill.

The Credit Agreement is secured by substantially all the real and personal property of DDB and is guaranteed, in part, by Benson Hill, the parent company, to a maximum of $7,000. The DDB Term Loan is payable in equal quarterly installments of $416 plus interest with the remaining balance of $5,972 due in April 2024. The DDB Equipment Loan is payable in equal quarterly installments of $175 plus interest through April 2024.

The interest rate on the DDB Term Loan and DDB Equipment Loan is equal to LIBOR plus 4.0% or 4.09% at June 30, 2021. The interest rate on the DDB Revolver is equal to LIBOR plus 3.5% or 3.59% at June 30, 2021.

Under the Credit Agreement, DDB and the Company must comply with certain financial covenants based on DDB’s operations, including a minimum working capital covenant, a minimum net worth covenant, a funded debt to EBITDA ratio covenant, and a fixed charge coverage ratio covenant.

Benson Hill as guarantor must also comply with a minimum cash covenant. The Credit Agreement also contains various restrictions on our activities, including restrictions on indebtedness, liens, investments, distributions, acquisitions and dispositions, control changes, transactions with affiliates, establishment of bank and brokerage accounts, sale-leaseback transactions, margin stocks, hazardous substances, hedging, and management agreements. During the first quarter of 2021 and the first and second quarters of 2020, we were in violation of certain financial covenants under the Credit Agreement, which were subsequently waived by the lender.

In the second quarter of 2020, the Revolver maturity date was extended to July 2021 and the Credit Agreement was amended to incorporate updated prospective financial covenants with respect to minimum working capital, minimum net worth, funded debt to EBITDA ratio, and fixed charge coverage ratio. In the first quarter of 2021, the Credit Agreement was further amended to clarify the definitions of net worth and EBITDA as used in the calculation of certain financial covenants.

11. Debt (continued)

In the second quarter of 2021, the Credit Agreement was further amended to adjust the non-financial covenants. Subsequent to the second quarter of 2021, the Revolver maturity date was extended to September 2021. While the Company is currently in compliance with the amended covenants, there is a risk that Benson Hill will not maintain compliance with the covenants, as discussed further in Note 1.

Notes Payable

In January 2020, the Company entered into a financing agreement with an investment firm which included a commitment by the lender to make term loans available to the Company in an amount of up to $35,000 with $20,000 available immediately and a second tranche of $15,000 available after the achievement of certain financial conditions including the issuance of additional equity by the Company (together the “Loan and Security Agreement”). Availability under the second tranche expired on December 2020.

In accordance with the Loan and Security Agreement, the Company executed term notes with the lender in February 2020 in the aggregate amount of $20,000 with a term of 51 months payable in interest only, at 12.5% interest in the amount of $208 for the first 15 months and principal and interest payments in the amount of $661 for the remaining 36 months with any remaining amount outstanding due May 2024. The term notes are secured by substantially all of the assets of the Company.

In connection with this lending relationship and the execution of the Loan and Security Agreement, the Company issued warrants to purchase preferred stock to the lender. The fair value of the warrants attributable to the funds loaned to the Company, estimated at $3,332 at issuance, were recorded as debt discount, which is amortized over the life of the term notes using the effective interest method and recorded as interest expense.

The fair value of the warrants attributable to the commitment to fund the second tranche, estimated at $1,248 at issuance, were recorded as a current asset and amortized through the date of commitment expiration using the straight-line method and recorded as interest expense. The option to draw down on the second tranche of $15,000 expired in December 2020 unused.

Under the terms of the Loan and Security Agreement, we must comply with certain affirmative and negative covenants. These covenants are primarily restrictions on our activities, including restrictions on indebtedness, liens, distributions, and significant business changes. During the first and second quarters of 2021 and 2020, we were in compliance with the covenants under the Loan and Security Agreement.

Paycheck Protection Program Loans

In April 2020, the Company received loan proceeds in the amount of approximately $5,102 under the Paycheck Protection Program. The program, established as part of the Coronavirus Aid, Relief and Economic Security Act, provides for loans to qualifying businesses for amounts up to 2.5 times of the average monthly payroll expenses of the qualifying business.

The Company subsequently repaid the loans in full in October 2020, including $25 of accrued interest.

12. Preferred Stock Warrant Liability

In connection with financing arrangements, in the first quarter of 2020, the Company issued 1,077 warrants to purchase Series C-1 preferred shares or any subsequent preferred share round of Benson Hill. The warrants are exercisable in the following scenarios and at the following purchase prices: (1) at the warrant holder’s discretion at any time before the expiration date (December 2035) at the stock purchase price of the preferred share round for which the warrant holder is converting into (($3.6837 — Series C-1) or

12. Preferred Stock Warrant Liability (continued)

($4.1416 — Series D)), or (2) upon the earliest to occur of (i) the expiration date, (ii) a change of control, or (iii) IPO, the warrants shall automatically exercise at no cost to the holder.

Should the Company consummate a bridge financing prior to a change of control or an IPO, the holders of the warrants may surrender their warrants to the Company and receive in exchange all of the same consideration, securities, instruments and rights as if the holder participated in the bridge financing with a loan in an amount equal to the shares issuable upon exercise of the warrants multiplied by the stock purchase price.

The pending business combination with Star Peak, outlined in Note 3 Merger with Star Peak Corp II, does not meet the definition of a change of control or an IPO.

13. Income Taxes

The Company’s effective tax rate was 0% for the three and six month periods ended June 30, 2021 and 2020. The 2021 and 2020 effective tax rates of 0% differed from the statutory rate of 21% due to the fact that the Company recorded no tax expense or benefit on the pretax losses as a full valuation allowance has been recorded globally.

14. Comprehensive Income

The Company’s other comprehensive income (“OCI”) consists of foreign currency translation adjustments from its Brazil subsidiary, which does not use the U.S. dollar as its functional currency, and unrealized gains and losses on marketable debt securities classified as available for sale.

The following table shows changes in accumulated other comprehensive income (“AOCI”) by component for the three and six months ended June 30, 2021 and 2020:

Amounts reclassified from AOCI were reported within “Other (income) expense, net” on the condensed consolidated statement of operations. The Company’s accounting policy is to release the income tax effects (if applicable) from AOCI when the individual units of account are sold.

15. Loss Per Common Share

The Company computes basic net income (loss) per share using the weighted average number of common shares outstanding during the period. Diluted net income (loss) per share is computed using the weighted average number of common shares and the effect of potentially dilutive securities outstanding during the period. Potentially dilutive securities may consist of convertible preferred stock, stock warrants, and stock options. The dilutive effect of outstanding preferred stock, stock warrants, and stock options are reflected in diluted earnings per share by application of the treasury stock method. The weighted average share impact of preferred stock, stock warrants, and stock options that were excluded from the calculation of diluted shares due to the Company incurring a net loss for the three and six month periods ending June 30, 2021 and 2020 were 110,835, 108,910, 68,275, and 68,292 shares, respectively.

The following table provides the basis for basic and diluted EPS by reconciling the numerators and denominators of the computations:

Diluted weighted average shares outstanding	​	6,323	​	5,634	​	6,092	​	5,597

16. Share-Based Compensation

Terms of the equity awards, including the vesting requirements are determined by the Board of Directors, subject to the provisions of the 2012 Stock Incentive Plan (the Plan). Stock options granted by the Company typically vest over one year for board members and four years for all other grants with a contractual life of ten years. The exercise price of an incentive stock option shall be not less than 100% of the fair market value of such shares on the date of grant.

The grant date fair value for the Company’s stock options granted in the six months ended June 30, 2021 and 2020, respectively, were based on the following assumptions used within the Black-Scholes option pricing model:

​	2021			2020
Expected dividend yield	​	​	0%	​	​	0%
Expected volatility	​	​	63%	​	​	58%
Risk-free interest rate	​	​	0.7%	​	​	1.0%
Expected term in years	6.1 years			6.2 years
Weighted average grant date fair value	​	$	1.54	​	$	0.81

The Company recognized $709 and $1,356 of compensation expense related to grants during the three and six months ended June 30, 2021, respectively. The Company recognized $217 and $504 of compensation expense related to grants during the three and six months ended June 30, 2020, respectively.

As of June 30, 2021 and 2020 the Company had 8,330 and 4,860 nonvested options, respectively.

17. Redeemable Convertible Preferred Stock

The carrying value of Redeemable Convertible Preferred Stock, net of offering costs outstanding consists of the following:

18. Commitments and Contingencies

Litigation

The Company accrues for cost related to contingencies when a loss is probable, and the amount is reasonably determinable. Disclosure of contingencies is included in the financial statements when it is at least reasonably possible that a material loss or an additional material loss in excess of amounts already accrued may be incurred.

The Company was the defendant in a lawsuit filed by J&J Produce Holdings, Inc. related to the acquisition of J&J in May 2019, whereby the plaintiff sought deferred purchase price payments in Chancery court in Delaware. This matter was settled in the first quarter of 2021.

Our subsidiary Benson Hill Seeds, Inc. was the defendant involved in two disputes related to the acquisition of Schillinger Genetics, Inc. The first dispute related to the termination of John Schillinger and alleged breach of obligations under the employment agreement with Mr. Schillinger. The second dispute involved the release of escrow funds related to the acquisition. This matter was settled in the second quarter of 2021.

For all litigation matters noted above and other individually immaterial matters, the Company accrued an immaterial amount and $2,675 as of June 30, 2021 and December 31, 2020, respectively, representing the final estimated settlement amounts some of which were paid out in the current year.

Other Commitments

As of June 30, 2021, we have committed to purchase from seed producers and growers at dates throughout 2021 and 2022 aggregating to $43.7 million based on current commodity futures or market prices, other payments to growers, and estimated yields per acre. This amount is not recorded in the condensed consolidated financial statements because we have not taken delivery of the grain or seed as of June 30, 2021 and as the grain and seed is subject to specified quality standards prior to delivery.

19. Segment Information

The Company’s reportable business segments reflect the manner in which its chief operating decision maker (“CODM”) allocates resources and assesses performance, which is at the operating segment level. The Fresh reportable segment is a grower, packer and distributor of year-round fresh produce located in the southeastern United States. The Ingredients reportable segment delivers healthy food ingredients derived from soybean seeds, meal and oil and processed yellow peas. Financial results associated with licensing arrangements that are not allocated to the Fresh or Ingredients reportable segment and costs associated with centralized operations are reported as Unallocated and other. Centralized operations represent corporate and headquarter-related expenses, which include legal, finance, human resources, and other research and development and administrative expenses that are not allocated to individual reporting operating segments.

Our CODM reviews segment performance and allocates resources based upon segment revenue and Adjusted EBITDA. The Company defines Adjusted EBITDA as earnings from continuing operations excluding income taxes, interest, depreciation, amortization, stock-based compensation, and the impact of significant non-recurring items.

All segment revenue is earned in the United States and there are no intersegment revenues. Operating segment results for the three and six month periods ended June 30, 2021 and 2020 are presented below.

For the three months ended June 30, 2021 we recognized $39,634 of revenue as of a point in time and $58 over time. For the six months ended June 30, 2021 we recognized $71,403 of revenue as of a point in time and $91 over time. For the three months ended June 30, 2020 we recognized $30,941 of revenue as of

a point in time and $87 over time. For the six months ended June 30, 2020 we recognized $62,447 of revenue as of a point in time and $167 over time. All revenue recognized over time is included in unallocated and other.

Upon consummation of the Merger, the separate corporate existence of Merger Sub shall cease and the Company, as the surviving corporation of the Merger (hereinafter referred to for the periods at and after the Effective Time as the “Surviving Corporation”), shall continue its corporate existence under the DGCL, as a wholly owned Subsidiary of STPC.

(b)   At and after the Effective Time, the Surviving Corporation shall thereupon and thereafter possess all of the assets, properties rights, privileges, powers and franchises, of a public as well as a private nature, of the Constituent Corporations, and shall become subject to all the debts, liabilities, restrictions, disabilities, obligations and duties of each of the Constituent Corporations in accordance with the applicable provisions of the DGCL.

As soon as practicable following the expiration of the sixty (60) day period following the date STPC has filed current Form 10 information with the SEC reflecting its status as an entity that is not a shell company, STPC shall file an effective registration statement on Form S-8 (or any successor form, or if Form S-8 is not available, other appropriate forms) with respect to the STPC Common Shares subject to the STPC Options and shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements (and maintain the current status of the prospectus or prospectuses contained therein) for so long as the STPC Options remain outstanding and are required to be registered. For the avoidance of doubt, at the Closing, incentive equity awards with a value equivalent to 2,037,320 STPC Common Shares (subject to adjustment pursuant to Section 2.2(f)) shall be granted under the New Incentive Plan to the Pre-Closing Holders that hold Company Options, pro rata in accordance with the relative number of Company Options held by such Pre-Closing Holder (“Earn Out Awards”).

(c)   Fractional Shares.   Notwithstanding anything in this Agreement to the contrary, no certificate or scrip representing fractional STPC Common Shares shall be issued pursuant to this Section 2.2, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of STPC. In lieu of any fractional shares, STPC shall cause each Pre-Closing Holder entitled to any portion of STPC Common Shares to be paid, and such holder shall be entitled to receive, an amount in cash, rounded up to the nearest cent, equal to the product obtained by multiplying (i) the fractional share interest to which such holder (after taking into account all Equity Securities held at the Effective Time by such holder) would otherwise be entitled by (ii) $10.

For illustrative purposes only, set forth on Section 2.2(e) of the Company Schedules is the Allocation Schedule as it would have been prepared if the Closing Date were the date hereof (it being understood that such illustrative Allocation Schedule set forth on Section 2.2(e) of the Company Schedules is illustrative only and not binding in any manner on the parties hereto); provided that, the Parties agree that such illustrative Allocation Schedule shall not be required to set forth the mailing addresses and email addresses for the Pre-Closing Holders.

Notwithstanding anything to the contrary, to the extent Company Options are exercised after the date hereof and prior to the Closing Date in accordance with a Company Equity Plan, or to the extent any Company Options are forfeited after the date hereof and prior to the Closing Date, the number of Earn Out Shares issued pursuant to Section 2.6 may be increased subject to a corresponding decrease in the number of Earn Out Awards to be granted at the Closing (which adjustment shall be in even-number increments constituting one $14 Earn Out Share for one $14 Earn Out Award and one $16 Earn Out Share for one $16 Earn Out Award), such that for each two (2) additional Earn Out Shares (one of which must be a $14 Earn Out Share and one of which must be a $16 Earn Out Share) in excess of the 17,562,680 Earn Out Shares contemplated to be issued pursuant to Section 2.6, the number of Earn Out Awards to be granted hereunder shall be reduced by one $14 Earn Out Award and one $16 Earn Out Award.

(f)   Notwithstanding any provision of this Agreement to the contrary, any share of Company Stock for which the holder (a “Dissenting Stockholder”) thereof (i) has not voted in favor of the Merger or consented to it in writing and (ii) has demanded the appraisal of such shares in accordance with, and has complied in all respects with, Section 262 of the DGCL (collectively, the “Dissenting Shares”) shall not be converted into the right to receive the portion of Total Merger Consideration (as divided between STPC Unrestricted Common Shares and Earn Out Shares) applicable to such Dissenting Shares in accordance with the Allocation Schedule and the terms of this Agreement; provided that any such amounts that would otherwise be payable in respect of such Dissenting Shares shall remain the property of STPC. From and after the Effective Time, (x) all Dissenting Shares shall be cancelled and cease to exist and (y) Dissenting Stockholders shall be entitled only to such rights as may be granted to them under Section 262 of the DGCL and shall not be entitled to exercise any of the voting rights or other rights of a stockholder of the Surviving Corporation. Notwithstanding the foregoing, if any Dissenting Stockholder effectively withdraws or loses such appraisal rights (through failure to perfect such appraisal rights or otherwise), then that Dissenting Stockholder’s shares (i) shall no longer be deemed to be Dissenting Shares and (ii) shall be treated as if they had been converted automatically at the Effective Time into the right to receive the portion of Total Merger Consideration (as divided between STPC Unrestricted Common Shares and Earn Out Shares) applicable to such Dissenting Shares in accordance with the Allocation Schedule upon delivery of a duly completed and validly executed Letter of Transmittal and the surrender of Certificates (if any) in accordance with Section 2.3(b). Each Dissenting Stockholder who becomes entitled to payment for his, her or its Dissenting Shares pursuant to the DGCL shall receive payment thereof from the Exchange Agent in accordance with the DGCL.

The Company shall give STPC prompt notice of any written demands for appraisal of any shares of Company Stock, attempted withdrawals of such demands and any other instruments served pursuant to the DGCL and received by the Company relating to stockholders’ rights of appraisal in accordance with the provisions of Section 262 of the DGCL, and STPC shall have the opportunity to participate in all negotiations and proceedings with respect to all such demands. The Company shall not, except with the prior written consent of STPC (prior to the Closing) or Sponsor (after the Closing), make any payment with respect to, settle or offer or agree to settle any such demands. Any portion of the Total Merger Consideration (as divided between STPC Unrestricted Common Shares and Earn Out Shares) made available to the Exchange Agent pursuant to Section 2.3(a) to pay for Dissenting Shares shall be returned to STPC upon demand.

Annex A-22

STPC shall send, or shall cause the Exchange Agent to send, to each Pre-Closing Holder that did not receive a Company Stockholder Package pursuant to Section 5.15, a Letter of Transmittal for use in such exchange. Following surrender of Certificates (to the extent certificated) to the Company and the Exchange Agent (together with a properly completed Letter of Transmittal) in the case of Pre-Closing Holders of Company Stock, such Pre-Closing Holders shall be entitled to receive the applicable portion of the Total Merger Consideration (as divided between STPC Unrestricted Common Shares and Earn Out Shares) in accordance with the Allocation Schedule within five (5) Business Days following such surrender and/or delivery of the applicable documents. No interest or dividends will be paid or accrued on the consideration payable upon delivery of a Letter of Transmittal. For the avoidance of doubt, to the extent the shares of Company Stock held by a Pre-Closing Holder of Company Stock are not certificated or are represented by electronic certificates, the requirement to deliver physical Certificates as set forth herein shall not apply.

(c)   No Further Transfers.   At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of any Company Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, any Company Stock is presented to the Surviving Corporation for any reason, they shall be cancelled and exchanged as provided in this Section 2.3.

Section 2.4   Exchange Agent.   Promptly following the date that is one year after the Effective Time, STPC shall instruct the Exchange Agent to deliver to STPC all cash, certificates and other documents in its possession relating to the transactions contemplated hereby, and the Exchange Agent’s duties shall terminate. Thereafter, each Pre-Closing Holder who has not delivered a Letter of Transmittal may surrender such Certificate (to the extent such shares are certificated) or deliver such Letter of Transmittal to STPC and (subject to applicable abandoned property, escheat and similar Laws) receive in consideration therefor, and STPC shall promptly pay, the portion of the Total Merger Consideration (as divided between STPC Unrestricted Common Shares and Earn Out Shares) deliverable in respect thereof as determined in accordance with this Article 2 without any interest thereon. None of STPC, Merger Sub, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any Person in respect of any Total Merger Consideration delivered to a public official pursuant to and in accordance with any applicable abandoned property, escheat or similar Laws. If any Certificate shall not have been surrendered immediately prior to such date on which any amounts payable pursuant to this Article 2 would otherwise escheat to or become the property of any Governmental Entity, any such amounts shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation, free and clear of all claims or interest of any Person previously entitled thereto.

Section 2.5   Withholding.   Notwithstanding any other provision in this Agreement to the contrary, STPC, the Company, and the Exchange Agent shall be entitled to deduct and withhold from any cash, stock consideration or other amounts otherwise paid or payable in connection with the transactions contemplated in this Agreement to any Person such amounts that STPC, the Company or the Exchange Agent are required to deduct and withhold with respect thereto under the Code or any provision of applicable Law; provided that before making any deduction or withholding pursuant to this Section 2.5 other than with respect to compensatory payments or as a result of the Company failing to deliver the certification required by Section 5.5(b), STPC shall use commercially reasonable efforts to give the Company at least five (5) Business Days prior written notice of any anticipated deduction or withholding (together with any legal basis thereof) to provide the Company with sufficient opportunity to provide any forms or other documentation from the applicable equity holders or take such other steps in order to avoid such deduction or withholding and shall reasonably consult and cooperate with the Company or the applicable Pre-Closing Holder in good faith to minimize or eliminate, to the extent permissible under applicable Law, the amount of any such deduction or withholding, including by cooperating with the submission of any certificates or forms to establish an exemption from, reduction in, or refund of any such deduction or withholding. To the extent that amounts so deducted and withheld are duly deposited with the appropriate Governmental Entity, such deducted and withheld amounts shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

Section 2.6   Earn-Out.

(b)   Upon receipt of the Earn Out Shares, an escrow agent (the “Earn Out Escrow Agent”) will place such Earn Out Shares in an escrow account (the “Earn Out Escrow Account”) established pursuant to an escrow agreement in the form attached hereto as Exhibit K, to be entered into at the Closing by STPC, the Holder Representative, the Sponsor and the Earn Out Escrow Agent (the “Earn Out Escrow Agreement”).

(c)   Subject to the limitations contemplated herein, each Earn Out Recipient shall have all of the rights of a stockholder with respect to the Earn Out Shares, including the right to receive dividends and to vote such shares; provided that the unvested Earn Out Shares shall not entitle the holder thereof to consideration in connection with any sale or other transaction (other than, for the avoidance of doubt, as part of a Company Sale) and may not be offered, sold, transferred, redeemed, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) by the Earn Out Recipients or be subject to execution, attachment or similar process without the consent of STPC, and shall bear a customary legend with respect to such transfer restrictions. The receipt of Earn Out Shares by the Earn Out Recipients is subject to the execution and delivery of a Lock-Up Agreement by each such holder on or prior to the Closing Date. In the event an Earn Out Recipient does not execute and deliver a Lock-Up Agreement, any Earn Out Shares that would otherwise be allocated to such holder shall be reallocated to the Earn Out Recipients that have executed and delivered a Lock-Up Agreement on a pro rata basis immediately prior to the Effective Time. Any attempt to sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of such unvested Earn Out Shares shall be null and void. Notwithstanding the foregoing, Earn Out Recipients who have executed a Lock-Up Agreement may transfer such Earn Out Recipient’s unvested Earn Out Shares solely to the extent such transfer would be a Permitted Transfer (as defined in such Earn Out Recipient’s Lock-Up Agreement), provided that the applicable permitted transferee and such transferred unvested Earn Out Shares shall otherwise be subject to the terms and conditions set forth in this Section 2.6.

(d)   If the applicable Triggering Event has not occurred prior to the expiration of the Earn Out Period, then all Earn Out Shares which would vest in connection with such Triggering Event shall be automatically forfeited and deemed transferred to STPC and shall be cancelled by STPC and cease to exist. For the avoidance of doubt, prior to such forfeiture, all Earn Out Shares shall be entitled to any dividends or distributions made to the holders of STPC Common Shares and shall be entitled to the voting rights generally granted to holders of STPC Common Shares.

(e)   In the event of occurrence of any Triggering Event set forth in Section 2.6(a), as soon as practicable (but in any event within three (3) Business Days), STPC will deliver to the Holder Representative a written statement (each, a “Stock Price Earn Out Statement”) that sets forth (i) the Closing Price over the applicable thirty- (30-) consecutive Trading Day period and (ii) the calculation of the Earn Out Shares in connection therewith and the Allocation Schedule, including any adjustments made pursuant to a stock split, stock dividend, reorganizations, recapitalizations and the like. The Holder Representative may deliver written notice

Annex A-24

to STPC on or prior to the fifteenth (15th) day after receipt of a Stock Price Earn Out Statement, either (x) accepting the Stock Price Earn Out Statement or (y) specifying in reasonable detail any items that they wish to dispute and the basis therefor. If the Holder Representative fails to deliver such written notice in such fifteen (15) day period, then the Earn Out Recipients will be deemed to have waived their right to contest such Stock Price Earn Out Statement and the calculations set forth therein, and such Stock Price Earn Out Statement and calculations set forth therein shall be deemed final and binding. If the Holder Representative provides STPC with written notice of any objections to the Stock Price Earn Out Statement in such fifteen (15) day period, then the Holder Representative and STPC will, for a period of fifteen (15) days following the date of delivery of such notice, attempt to resolve their differences and any written resolution by them as to any disputed amount will be final and binding for all purposes under this Agreement. If at the conclusion of such fifteen (15) day period the Holder Representative and STPC have not reached an agreement on any objections with respect to the Stock Price Earn Out Statement, then upon the written request of either STPC or the Holder Representative, the dispute shall be referred to an independent accountant of national standing as shall be mutually agreed upon in good faith by STPC and the Holder Representative for final resolution of the dispute as promptly as practicable. Upon final determination of the items set forth in the Stock Price Earn Out Statement as contemplated by this Section 2.6(e), the applicable Earn Out Shares shall be deemed to have vested upon such applicable Triggering Event in accordance with such Stock Price Earn Out Statement. Promptly thereafter, STPC shall prepare and deliver or cause to be prepared and delivered, in consultation with the Sponsor and the Holder Representative, a mutually agreeable written notice to the Earn Out Escrow Agent (a “Release Notice”), which Release Notice shall set forth in reasonable detail, the Triggering Event giving rise to the requested release and the specific release instructions with respect thereto (including the number of Earn Out Shares to be released and the identity of the person to whom such Earn Out Shares should be released). In the event STPC fails to deliver the Stock Price Earn Out Statement within the three (3) Business Day period described above, the Holder Representative shall be entitled to deliver the Stock Price Earn Out Statement, and any disputes and the resolution process set forth in this Section 2.6(e) shall, in such circumstances, apply mutatis mutandis.

(f)   In the event that there is a Company Sale after the Closing and prior to the expiration of the Earn Out Period, if the sale price per share or implied sale price per share based on the company sale price at the closing of the Company Sale is at least $14 (with respect to Triggering Event I and the $14 Earn Out Shares) or $16 (with respect to Triggering Event II and the $16 Earn Out Shares), in each case, taking into account the number of Earn Out Shares that would be vested as if the STPC Common Shares had been trading at a Closing Price equal to such sale price per share or implied sale price per share in connection with such Company Sale, as applicable, for the requisite period set forth in Section 2.6(a) necessary to satisfy the applicable Triggering Event, then (A) immediately prior to the consummation of the Company Sale, Triggering Event I or Triggering Event II (as applicable) that has not previously occurred shall be and the related vesting conditions in Section 2.6(e) also shall be deemed to have occurred, (B) such Earn Out Shares shall immediately vest and be released from the Earn Out Escrow Account, and distributed to each Earn Out Recipient entitled to such Earn Out Shares and (C) the holders of such Earn Out Shares shall be eligible to participate in such Company Sale.

Section 5.2   Efforts to Consummate.

(a)   Subject to the terms and conditions herein provided, each of the Parties shall use its reasonable best efforts to take, or cause to be taken, all action and to do, or cause to be done, all things reasonably necessary, proper or advisable to consummate and make effective as promptly as practicable the transactions contemplated by this Agreement (including the satisfaction, but not waiver, of the Closing conditions set forth in Article 6 and, in the case of any Ancillary Document to which such Party will be a party to upon the execution thereof, the execution and delivery of such Ancillary Document).

Annex A-51

Agreement and (ii) respond as promptly as practicable to any requests by any Governmental Entity for additional information and documentary material that may be requested pursuant to the HSR Act.

Each of the Parties agrees not to participate in any substantive meeting or discussion, either in person or by telephone with any Governmental Entity in connection with the transactions contemplated by this Agreement unless it consults with, in the case of any STPC Party, the Company, or, in the case of the Company, STPC, in advance and, to the extent reasonably practicable and not prohibited by such Governmental Entity, gives, in the case of any STPC Party, the Company, or, in the case of the Company, STPC, the opportunity to attend and participate in such meeting or discussion (which, at the request of STPC, will be limited to outside antitrust counsel only).

(d)   In furtherance of, and without limiting the Parties’ obligations pursuant to, Section 5.2(a), the Company shall use commercially reasonable efforts to obtain, prior to the Closing, written consents, in form and substance reasonably acceptable to STPC, from each of the counterparties to the agreements set forth on Section 5.2(d) of the Company Schedules; provided that nothing herein shall require a Party or any of its respective Affiliates to expend money, commence any Proceeding or offer or grant any accommodation (financial or otherwise) to any third party. All costs incurred in connection with obtaining such consents shall be Company Expenses.

(e)   Notwithstanding anything to the contrary in the Agreement, in the event that this Section 5.2 conflicts with any other covenant or agreement in this Article 5 that is intended to specifically address any subject matter, then such other covenant or agreement shall govern and control solely to the extent of such conflict.

Section 5.3   Access to Information.   Solely for the purposes of consummating the transactions contemplated by this Agreement and the Ancillary Documents, from and after the date of this Agreement until the earlier of the Closing Date or the termination of this Agreement in accordance with its terms, upon reasonable advance written notice, the Company shall provide, or cause to be provided, to STPC and its Representatives during normal business hours reasonable access to all of the employees, properties, Contracts, and books and records of the Group Companies (in a manner so as to not interfere with the normal business operations of the Group Companies). All of such information shall be treated as “Confidential

Annex A-52

Information” ​(or the applicable equivalent term) pursuant to the terms of the Confidentiality Agreement, the provisions of which are by this reference hereby incorporated herein. Notwithstanding the foregoing, none of the Group Companies shall be required to disclose to STPC or any of its Representatives any information (i) if and to the extent doing so (A) would violate any applicable Law, (B) could, as reasonably determined upon the advice of outside legal counsel, result in the loss of the ability to successfully assert any attorney-client or work product privilege (provided that, in case of each of (A) and (B), the Company shall, and shall cause the other Group Companies to, use commercially reasonable efforts to provide (x) such access as can be provided (or otherwise convey such information regarding the applicable matter as can be conveyed) or (y) such information in a manner without violating such privilege, Contract or Law), (ii) if any Group Company, on the one hand, and STPC or any of its Representatives, on the other hand, are adverse parties in a litigation and such information is reasonably pertinent thereto; provided that the Company shall, in the case of clause (i) or (ii), provide prompt written notice of the withholding of access or information on any such basis, or (iii) that is a Trade Secret. The Parties hereby acknowledge and agree that the Confidentiality Agreement shall be automatically terminated effective as of the Closing without any further action by any Party or any other Person.

Notwithstanding anything to the contrary in this Section 5.4 or otherwise in this Agreement, the Parties agree that Sponsor, STPC and their respective Representatives may provide general information about the subject matter of this Agreement and the transactions contemplated hereby to any direct or indirect current or prospective investor (including in connection with the PIPE Financing) or in connection with normal fund raising or related marketing or informational or reporting activities. Furthermore, between the date hereof and the Closing Date, the Company shall not, and each shall cause its Subsidiaries not to, make any broad-based announcements or disclosures regarding the transactions contemplated hereby or any Ancillary Document to any of their respective employees, customers, suppliers or other business relationships without the prior written consent of STPC (not to be unreasonably withheld, delayed or conditioned).

(b)   The initial press release concerning this Agreement and the transactions contemplated hereby shall be a joint press release in the form agreed by the Company and STPC prior to the execution of this Agreement and such initial press release (the “Signing Press Release”) shall be released as promptly as practicable after the execution of this Agreement (but in any event within four (4) Business Days thereafter).

The Company, STPC and Sponsor shall mutually agree upon (such agreement not to be unreasonably withheld, conditioned or delayed by any of them) and, as promptly as practicable after the Closing (but in any event within four (4) Business Days thereafter), issue a press release announcing the consummation of the transactions contemplated by this Agreement (the “Closing Press Release”). Promptly after the Closing (but in any event within four (4) Business Days after the Closing), STPC shall file a current report on Form 8-K (the “Closing Filing”) with the Closing Press Release and a description of the Closing as required by Securities Laws, which Sponsor shall have the opportunity to review and comment upon prior to filing and STPC shall consider in good faith such comments.

(c)   Without limiting the foregoing, from and after the date of this Agreement until the earlier of the Closing Date or the termination of this Agreement in accordance with its terms, the Company shall maintain, and shall cause its Affiliates who are in possession of any material non-public information, written or oral, it or they may have to the extent regarding STPC or any of its Affiliates, including this Agreement and its terms and conditions (“STPC Confidential Information”), to maintain such STPC Confidential Information, in confidence, and such information shall not be disclosed or used by the Company or its Affiliates for any purpose without STPC’s prior written consent, unless such information: (i) is or becomes otherwise publicly available through no breach by the Company or its Affiliates of this Section 5.4(c), (ii) is required to be disclosed by applicable Law or the rules of any stock exchange, in which case the disclosing Party shall, to the extent permitted by applicable Law, notify STPC in advance of such disclosure, (iii) is requested or required to be disclosed by a Governmental Entity in connection with any Proceeding, audit or investigation of any Group Company, in which case the disclosing Party shall, to the extent permitted by applicable Law, notify STPC in advance of such disclosure (provided that such notice shall not be required in connection with any routine audit or examination not targeting STPC or the transactions contemplated by this Agreement), (iv) is disclosed to the Company’s Representatives and agents solely for the purposes of evaluating, negotiating, executing and consummating the transaction contemplated by this Agreement and the Ancillary Documents, or (v) is disclosed or used in connection with any Proceeding to enforce the rights of the Company or its Affiliates under this Agreement or any Ancillary Document.

Section 5.5   Indemnification; Directors’ and Officers’ Insurance.

(a)   STPC agrees that (i) all rights to indemnification or exculpation now existing in favor of the directors and officers of each Group Company, as provided in a Group Company’s Governing Documents or otherwise in effect as of the date of this Agreement and set forth on Section 5.5(a) of the Company Schedules, in either case, solely with respect to any matters occurring on or prior to the Closing, shall survive the transactions contemplated by this Agreement and shall continue in full force and effect from and after the Closing for a period of six (6) years, and (ii) the Group Companies will perform and discharge all obligations to provide such indemnity and exculpation during such six (6) year period. To the maximum extent permitted by applicable Law, during such six (6) year period, the Group Companies shall advance expenses in connection with such indemnification as provided in such Group Company’s Governing Documents or other applicable agreements. The indemnification and liability limitation or exculpation provisions of the Group Companies’ Governing Documents shall not, during such six (6) year period, be amended, repealed or otherwise modified after the Closing in any manner that would materially and adversely affect the rights thereunder of individuals who, as of the Closing or at any time prior to the Closing, were directors or officers of any Group Company (the “D&O Persons”) to be so indemnified, have their liability limited or be exculpated with respect to any matters occurring prior to Closing and relating to the fact that such D&O Person was a director or officer of any Group Company prior to the Closing, unless such amendment, repeal or other modification is required by applicable Law.

(b)   Neither STPC nor any Group Company shall have any obligation under this Section 5.5 to any D&O Person when and if a court of competent jurisdiction shall ultimately determine (and such determination shall have become final and non-appealable) that the indemnification of such D&O Person in the manner contemplated hereby is prohibited by applicable Law.

(c)   The Company shall cause the Group Companies to purchase, at or prior to the Closing, and STPC shall cause the Group Companies to maintain in effect for a period of six (6) years after the Closing Date, without lapses in coverage, a “tail” policy or policies providing directors’ and officers’ liability insurance coverage for the benefit of those Persons who are currently covered by any comparable insurance policies of the Group Companies as of the date hereof (the “Company D&O Tail Policy”). Such Company D&O Tail Policies shall provide coverage on terms (with respect to coverage and amount) that are substantially the same as (and no less favorable in the aggregate to the insured than) the coverage provided under the Group Companies’ directors’ and officers’ liability insurance policies as of the date hereof; provided that the Group Companies shall not pay a premium for the Company D&O Tail Policy in excess of 300% of the most recent annual premium paid by the Group Companies, as applicable, prior to the date of this Agreement

Annex A-54

and, in such event, the Group Companies shall purchase the maximum coverage available for 300% of the most recent annual premium paid by the Group Companies prior to the date of this Agreement.

(d)   Prior to the Effective Time, STPC may purchase a prepaid “tail” policy (a “STPC Tail Policy”) with respect to directors’ and officers’ liability insurance coverage for the benefit of those Persons who are currently covered by any comparable insurance policies of STPC’s as of the date hereof, which STPC Tail Policy shall be on the same or substantially similar terms agreed to for such tail policy by STPC in connection with its initial public offering. If STPC elects to purchase such a STPC Tail Policy prior to the Effective Time, STPC will maintain such STPC Tail Policy in full force and effect for a period of no less than six (6) years after the Closing Date and continue to honor its obligations thereunder.

(e)   If STPC, any Group Company or any of their respective successors or assigns (i) shall merge or consolidate with or merge into any other corporation or entity and shall not be the surviving or continuing corporation or entity of such consolidation or merger or (ii) shall transfer all or substantially all of their respective properties and assets as an entity in one or a series of related transactions to any Person, then in each such case, proper provisions shall be made so that the successors or assigns of STPC or such Group Company shall assume all of the obligations set forth in this Section 5.5 unless otherwise assumed by operation of Law.

(f)   The D&O Persons entitled to the indemnification, liability limitation, exculpation and insurance set forth in this Section 5.5 are intended to be third party beneficiaries of this Section 5.5. This Section 5.5 shall survive the consummation of the transactions contemplated by this Agreement and shall be binding on all successors and assigns of STPC and the Group Companies. The rights of each D&O Person hereunder shall be in addition to, and not in limitation of, any other rights such Person may have under the Governing Documents of any Group Company, any other indemnification arrangement, any applicable Law or otherwise.

Section 5.6   Tax Matters.

(a)   Tax Treatment.

(i)   Each of the Parties intend that the Merger shall constitute a transaction that qualifies as a “reorganization” within the meaning of Section 368(a) of the Code, and each Party shall, and shall cause its respective Affiliates to, use reasonable best efforts to so qualify and shall prepare and file all Tax Returns consistent with, and take no position inconsistent with (whether in Tax Returns, Tax Proceedings, or otherwise) such treatment unless required to do so pursuant to a “determination” within the meaning of Section 1313(a) of the Code.

(ii)   The STPC Parties and the Company hereby adopt this Agreement as a “plan of reorganization” for the purposes of Section 368 of the Code and Treasury Regulations Sections 1.368-2(g) and 1.368-3(a).

(b)   FIRPTA Certificate.   STPC hereby requests, and the Company shall deliver to STPC prior to the Closing, (i) a certificate pursuant to Treasury Regulations Sections 1.1445-2(c)(3) and 1.897-2(h), dated not more than thirty (30) days prior to the Closing Date and signed by an executive officer of the Company, certifying that the equity interests in the Company are not “United States real property interests” ​(as defined in Section 897(c)(1) of the Code), (ii) a copy of the notification provided to the Internal Revenue Service regarding such certificate, in accordance with the provisions of Treasury Regulations Section 1.897-2(h)(2), and (iii) a duly executed IRS Form W-9 from the Company.

(d)   STPC shall be responsible for and shall pay all local, non-U.S. or other excise, sales, use, value-added, transfer (including real property transfer), stamp, documentary, filing, recordation and other similar Taxes and fees that may be imposed or assessed as a result of the execution of, and the transactions contemplated by, this Agreement, together with any inflation adjustment, interest, additions or penalties with respect thereto, including any inflation adjustment or interest with respect to such additions or penalties (“Transfer Taxes”). STPC shall, at its own expense, file all necessary Tax Returns and other documentation with respect to all such Transfer Taxes.

Section 5.7   Financing.

(a)   STPC shall use its reasonable best efforts to obtain the PIPE Financing (and the Company shall reasonably cooperate with STPC in connection thereto) on a timely basis on the terms and conditions described in the Subscription Agreements, including using its reasonable best efforts to (i) comply with its respective obligations under the Subscription Agreements, (ii) maintain in effect the Subscription Agreements in accordance with the terms and conditions thereof, (iii) satisfy on a timely basis all conditions and covenants applicable to STPC set forth in the applicable Subscription Agreements within its control, and (iv) consummate the PIPE Financing when required pursuant to this Agreement.

Other than as set forth in this Section 5.7(a) or Section 5.7(b), STPC shall not, without the prior written consent of the Company, amend, modify, supplement or waive any provision of, nor terminate or abandon its plans with respect to, any Subscription Agreement.

(b)   If all or any portion of the PIPE Financing becomes unavailable, (i) STPC shall promptly use its reasonable best efforts to promptly obtain the PIPE Financing or such portion of the PIPE Financing from alternative sources in an amount, when added to any portion of the PIPE Financing that is available, equal to the PIPE Financing Amount (any alternative source(s) of financing, “Alternative PIPE Financing”) and (ii) in the event that STPC is able to obtain any Alternative PIPE Financing, STPC shall use its reasonable best efforts to enter into a new subscription agreement (each, an “Alternative Subscription Agreement”) that provides for the subscription and purchase of STPC Class A Shares containing terms and conditions not less favorable from the standpoint of STPC, Sponsor and the Company than those in the Subscription Agreements entered into as of the date hereof (as determined in the reasonable good faith judgment of STPC, Sponsor and the Company). In such event, the term “PIPE Financing” as used in this Agreement shall be deemed to include any Alternative PIPE Financing, the term “Subscription Agreements” as used in this Agreement shall be deemed to include any Alternative Subscription Agreement and the term “PIPE Investor” as used in this Agreement shall be deemed to include any Person that is subscribing for STPC Class A Shares under any Alternative Subscription Agreement. For the avoidance of doubt, if all or any portion of the PIPE Financing or Alternative PIPE Financing becomes unavailable, STPC may utilize deposits, proceeds or any other amounts from the Trust Account and, to the extent acceptable to the Company, any additional third-party financing to satisfy its financing obligations hereunder (including to satisfy the Minimum Cash Condition).

The specification of any dollar amount in the representations, warranties or covenants set forth in this Agreement or the inclusion of any specific item in any Schedule is not intended to imply that such amounts, or higher or lower amounts or the items so included or other items, are or are not material or are within or outside of the ordinary course of business or consistent with past practice, and no Party shall use the fact of the setting of such amounts or the inclusion of any such item in any dispute or controversy as to whether any obligation, items or matter not described herein or included in a Schedule is or is not material for purposes of this Agreement.

Section 8.10   Severability.   Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the Parties shall negotiate in good faith to modify this Agreement so as to effect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

The use of electronic signatures and electronic records (including, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect,

Annex A-71

validity and enforceability as a manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the Delaware Uniform Electronic Transactions Act and any other applicable law. Minor variations in the form of the signature page, including footers from earlier versions of this Agreement or any such other document, shall be disregarded in determining the party’s intent or the effectiveness of such signature.

Section 8.12   Knowledge of Company; Knowledge of STPC.   For all purposes of this Agreement, the phrase “to the Company’s knowledge” and “known by the Company” and any derivations thereof shall mean as of the applicable date, the actual knowledge of the individuals set forth on Section 8.12(a) of the Company Schedules, assuming reasonable due inquiry and investigation. For all purposes of this Agreement, the phrase “to STPC’s knowledge” and “to the knowledge of STPC” and any derivations thereof shall mean as of the applicable date, the actual knowledge of the individuals set forth on Section 8.12(b) of the STPC Schedules, assuming reasonable due inquiry and investigation. For the avoidance of doubt, none of the individuals set forth on Section 8.12(a) of the Company Schedules or Section 8.12(b) of the STPC Schedules shall have any personal liability or obligations regarding such knowledge.

Section 8.13   No Recourse.   All Proceedings, liabilities and causes of action (whether in contract or in tort, in Law or in equity or granted by statute) that may be based upon, be in respect of, arise under, out or by reason of, be connected with or relate in any manner to this Agreement, or the negotiation, execution or performance of this Agreement (including any representation or warranty made in this Agreement), may be made against only (and such representations and warranties are those solely of) the Persons that are expressly identified herein as Parties and their respective successors and permitted assigns. No Person who is not a Party, including any current, former or future director, officer, founder, employee, consultant, incorporator, member, partner, manager, shareholder, Affiliate, agent, attorney, representative, successor or assignee of, and any financial advisor to, any Party, or any current, former or future director, officer, employee, consultant, incorporator, member, partner, manager, shareholder, Affiliate, agent, attorney, representative, successor or assignee of, and any financial advisor to, any of the foregoing, and in the case of STPC, Sponsor (or any successor or assignee thereof) (each in their capacity as such, a “Nonparty Affiliate”), shall have any liability (whether in contract or in tort, in Law or in equity, or granted by statute) for any Proceedings, liabilities or causes of action arising under, out or by reason of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance or breach, and, to the maximum extent permitted by Law, each Party hereby waives and releases all such Proceedings, liabilities and causes of action against any such Nonparty Affiliates.

Section 8.14   Extension; Waiver.   The Company may, prior to the Closing, (a) extend the time for the performance of any of the obligations or other acts of any STPC Party set forth herein, (b) waive any inaccuracies in the representations and warranties of any STPC Party set forth herein, or (c) waive compliance by any STPC Party with any of the agreements or conditions set forth herein. STPC may (prior to the Closing) and Sponsor may (after the Closing) (in either case, on behalf of itself, and any other STPC Party) (i) extend the time for the performance of any of the obligations or other acts of the Company set forth herein, (ii) waive any inaccuracies in the representations and warranties of the Pre-Closing Holder or the Company set forth herein, or (iii) waive compliance by the Company with any of the agreements or conditions set forth herein. Any agreement on the part of any Party or Sponsor to any such extension or waiver shall be valid only if set forth in a written instrument signed on behalf of such Person. Any waiver of any term or condition shall not be construed as a waiver of any subsequent breach or a subsequent waiver of the same term or condition, or a waiver of any other term or condition of this Agreement. The failure of any Party or Sponsor to assert any of its rights hereunder shall not constitute a waiver of such rights.

Section 8.15   Waiver of Jury Trial.   THE PARTIES EACH HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR UNDER ANY ANCILLARY DOCUMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES IN RESPECT OF THIS AGREEMENT OR ANY ANCILLARY DOCUMENT OR ANY OF THE TRANSACTIONS RELATED HERETO OR THERETO OR ANY FINANCING IN CONNECTION WITH THE TRANSACTIONS CONTEMPLATED HEREBY OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY,

Annex A-72

INCLUDING IN RESPECT OF ANY ACTION AGAINST ANY FINANCING SOURCE (IF ANY), IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES EACH HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

Section 8.16   Jurisdiction.   Any Proceeding based upon, arising out of or related to this Agreement or the transactions contemplated hereby must be brought in the Court of Chancery of the State of Delaware (or, to the extent such Court does not have subject matter jurisdiction, the Superior Court of the State of Delaware), or, if it has or can acquire jurisdiction, in the United States District Court for the District of Delaware, and each of the parties irrevocably submits to the exclusive jurisdiction of each such court in any such Proceeding, waives any objection it may now or hereafter have to personal jurisdiction, venue or to convenience of forum, agrees that all claims in respect of the Proceeding shall be heard and determined only in any such court, and agrees not to bring any Proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in any other court. Nothing herein contained shall be deemed to affect the right of any party to serve process in any manner permitted by Law or to commence legal Proceedings or otherwise proceed against any other party in any other jurisdiction, in each case, to enforce judgments obtained in any Proceeding brought pursuant to this Section 8.16.

Section 8.17   Remedies.   Except as otherwise expressly provided herein, any and all remedies provided herein will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by Law or equity upon such Party, and the exercise by a Party of any one remedy will not preclude the exercise of any other remedy. The failure on the part of any Party to exercise, and no delay in exercising, any right, power, or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of such right, power, or remedy by such Party preclude any other or further exercise thereof or the exercise of any other right, power, or remedy. The Parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the Parties do not perform their respective obligations under the provisions of this Agreement (including failing to take such actions as are required of them hereunder to consummate the transactions contemplated by this Agreement) in accordance with their specific terms or otherwise breach such provisions. It is accordingly agreed that the Parties shall be entitled to an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in each case without posting a bond or undertaking and without proof of damages and this being in addition to any other remedy to which they are entitled at Law or in equity. Each of the Parties agrees that it will not oppose the granting of an injunction, specific performance and other equitable relief when expressly available pursuant to the terms of this Agreement on the basis that the other parties have an adequate remedy at Law or an award of specific performance is not an appropriate remedy for any reason at Law or equity.

Section 8.18   Legal Representation.   STPC hereby agrees on behalf of its directors, members, partners, officers, employees and Affiliates (including after the Closing, the Company), and each of their respective successors and assigns (all such parties, the “Waiving Parties”), that Winston & Strawn LLP (or any successor) (“W&S”) may represent the Pre-Closing Holders or any of their respective directors, members, partners, officers, employees or Affiliates (other than the Company) (collectively, the “Benson Hill Group”), in each case, in connection with any Proceeding or obligation arising out of or relating to this Agreement, any Ancillary Document or any of the transactions contemplated hereby or thereby, notwithstanding its representation (or any continued representation) of the Group Companies or other Waiving Parties, and each of STPC and the Company on behalf of itself and the Waiving Parties hereby consents thereto and irrevocably waives (and will not assert) any conflict of interest, breach of duty or any other objection arising therefrom or relating thereto. STPC and the Company acknowledge that the foregoing provision applies whether or not W&S provides legal services to any Group Companies after the Closing Date. Each of STPC and the Company, for itself and the Waiving Parties, hereby further irrevocably acknowledges and agrees that all communications, written or oral, between any Group Company or any member of the Benson Hill Group and its counsel, including W&S, made in connection with the negotiation, preparation,

Annex A-73

execution, delivery and performance under, or any dispute or Proceeding arising out of or relating to, this Agreement, any Ancillary Document or the transactions contemplated hereby or thereby, or any matter relating to any of the foregoing, are privileged communications that do not pass to the Company notwithstanding the Merger, and instead survive, remain with and are controlled by the Benson Hill Group (the “Privileged Communications”), without any waiver thereof. STPC and the Company, together with any of their respective Affiliates, Subsidiaries, successors or assigns, agree that no Person may use or rely on any of the Privileged Communications, whether located in the records or email server of the Company or otherwise (including in the knowledge or the officers and employees of the Company), in any Proceeding against or involving any of the Parties after the Closing, and STPC and the Company agree not to assert that any privilege has been waived as to the Privileged Communications, whether located in the records or email server of the Company or otherwise (including in the knowledge of the officers and employees of the Company).

Section 8.19   Trust Account Waiver.   Reference is made to the final prospectus of STPC, dated as of January 5, 2021, filed with the SEC (File No. 333-251488) on January 7, 2021 (the “Prospectus”). The Company acknowledges and agree and understand that STPC 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 STPC’s public shareholders (including overallotment shares acquired by STPC’s underwriters, the “Public Shareholders”), and STPC may disburse monies from the Trust Account only in the express circumstances described in the Prospectus. For and in consideration of STPC entering into this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Company hereby agrees on behalf of itself and its Representatives that, notwithstanding anything to the contrary in this Agreement, none of the Company, any Pre-Closing Holder, or any of their respective Representatives does now or shall at any time hereafter have any right, title, interest or claim of any kind in or to any monies in the Trust Account or distribution therefrom to Public Shareholders or otherwise occurring prior to the Closing in accordance with the terms of the Trust Agreement, or make any claim against the Trust Account (including any distributions therefrom), regardless of whether such claim arises as a result of, in connection with or relating in any way to, this 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 “Trust Account Released Claims”). The Company on his, her or its own behalf and on behalf of his, her or its respective Representatives hereby irrevocably waives any Trust Account Released Claims that such Person and his, her or its respective Representatives may have against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, any negotiations, or Contracts with STPC or its Representatives and will not seek recourse against the Trust Account (including any distributions therefrom) for any reason whatsoever (including for an alleged breach of any agreement with STPC or its Affiliates); provided, however, that STPC acknowledges and agrees that the foregoing shall not limit or prohibit any claims that the Company may have in the future pursuant to this Agreement or any Ancillary Document or related to the transactions contemplated hereby against STPC’s assets or funds that are not held in the Trust Account, including funds that have been released from the Trust Account to STPC upon the consummation of an initial business combination by STPC, and for the avoidance of doubt not including funds released to the Public Shareholders in respect of redemptions or to STPC’s underwriters for payment of their deferred discount from the IPO.

Section 8.20   Holder Representative.

(a)   Notwithstanding anything herein to the contrary, the Company shall use commercially reasonable efforts to appoint a Holder Representative prior to the Closing, on customary terms and conditions and enter into any Contract with such Holder Representative on customary terms and conditions. By consenting to this Agreement, executing a Letter of Transmittal or accepting any consideration as contemplated by Article 2, each Pre-Closing Holder appoints, authorizes and empowers the Holder Representative to act as a representative for the benefit of the Pre-Closing Holders, as the sole and exclusive agent and attorney-in-fact to act on behalf of each Pre-Closing Holder for purposes of Section 2.6 under this Agreement and the Ancillary Documents following the Closing. Without limiting the generality of the foregoing, the Holder Representative shall have the full power and authority to take any and all actions on behalf of the Pre-Closing Holders that is necessary, appropriate or desirable to carry out all of the duties, responsibilities and obligations of the Holder Representative under this Agreement and the Ancillary Documents, including

Annex A-74

the power and authority to: (i) interpret the terms and provisions of this Agreement and the documents to be executed and delivered in connection herewith; (ii) execute and deliver, and receive deliveries of, all agreements, certificates, statements, notices, approvals, extension, waivers, undertakings, and other documents required or permitted to be given in connection with Section 2.6 of this Agreement, (iii) receive service of process in connection with any claims made pursuant to Section 2.6 of this Agreement; (iv) make any calculations and determinations and settle any matters on behalf of all Pre-Closing Holders in connection with Section 2.6 of this Agreement, and in connection therewith issue notices and instructions to the Exchange Agent in accordance with the terms of the applicable Ancillary Documents; (v) assert or pursue on behalf of the Pre-Closing Holders any Proceeding or investigation against any of the other Parties, consenting to, compromising or settling any such Proceedings or investigations, conducting negotiations with any of the other Parties and their respective Representatives regarding such Proceeding or investigations pursuant to Section 2.6 of this Agreement, and, in connection therewith, to: (A) assert or institute any Proceeding or investigation; (B) file any proofs of debt, claims and petitions as the Holder Representative may deem advisable or necessary; and (C) file and prosecute appeals from any decision, judgment or award rendered in any such Proceeding or investigation; and (vi) to make, execute, acknowledge and deliver all such other statements, agreements, guarantees, orders, receipts, endorsements, notices, requests, instructions, certificates, stock powers, letters and other writings, and, in general, to do any and all things and to take any and all action that the Holder Representative, in its sole and absolute discretion, may consider necessary or proper or convenient in connection with or to carry out the transactions contemplated by Section 2.6 of this Agreement and all Ancillary Documents to which Holder Representative is party (including, for the avoidance of doubt, in connection with Article 2).

(b)   STPC, Sponsor, and any other Person may conclusively and absolutely rely, without inquiry, upon any action or decision of the Holder Representative in all matters referred to herein. STPC and Sponsor are entitled to deal exclusively with the Holder Representative on all matters arising under or in connection with Section 2.6 or this Section 8.20. Any action taken or not taken or decisions, communications or writings made, given or executed by the Holder Representative with respect to all such matters, for or on behalf of any Pre-Closing Holder, shall be deemed an action taken or not taken or decisions, communications or writings made, given or executed by such Pre-Closing Holder. Any notice or communication delivered to the Holder Representative pursuant to Section 2.6 or this Section 8.20 shall be deemed to have been delivered to all the Pre-Closing Holder. STPC and Sponsor shall be entitled to disregard any decisions, communications or writings made, given or executed by any Pre-Closing Holder in connection with any matter arising under or in connection with Section 2.6 or this Section 8.20, unless the same is made, given or executed by the Holder Representative.

(c)   The appointment of the Holder Representative as each Pre-Closing Holder’s attorney-in-fact revokes any power of attorney heretofore granted that authorized any other Person or Persons to act as agent and to represent such Pre-Closing Holder with regard to the matters contemplated by Section 2.6 or this Section 8.20. The grant of authority provided for herein (i) is coupled with an interest and shall be irrevocable and survive the death, incompetency, bankruptcy, or liquidation of any Pre-Closing Holder, and (ii) shall survive the consummation of transactions contemplated by this Agreement. Notwithstanding the foregoing, (A) the Holder Representative may be removed from its position by the Pre-Closing Holders holding a majority of the Company Stock outstanding as of immediately prior to the Effective Time by providing written notice to the then-serving Holder Representative and STPC (prior to the Closing) or Sponsor (after the Closing) and (B) the Holder Representative may resign as the Holder Representative at any time by providing written notice to STPC (prior to the Closing) or Sponsor (after the Closing), which resignation shall become effective upon appointment of a successor Holder Representative. Any vacancy of the Holder Representative (whether resulting from resignation, death or removal) shall be filled by a successor Holder Representative appointed by the Pre-Closing Holders holding a majority of the Company Stock outstanding as of immediately prior to the Effective Time; provided that such successor Holder Representative must be reasonably acceptable to STPC (prior to the Closing) or Sponsor (after the Closing). All power, authority, rights, privileges, and obligations conferred in this Agreement to the Holder Representative shall apply to any such successor Holder Representative.

(d)   Following the Closing, the Holder Representative shall be reimbursed by STPC for any and all reasonable and documented expenses, disbursements, costs and advances incurred by the Holder Representative in his capacity as such.

Annex A-75

(e)   The Holder Representative shall not be liable for any action taken, suffered or omitted to be taken by it in good faith except to the extent that a final adjudication of a court of competent jurisdiction determines that the Holder Representative’s gross negligence or willful misconduct was the cause of any loss to the Pre-Closing Holders. The Pre-Closing Holders shall indemnify and hold the Holder Representative harmless from and against, and the Holder Representative shall not be responsible for, any losses arising out of or attributable to the Holder Representative’s duties under this Agreement or this appointment, except to the extent that such losses are determined by a court of competent jurisdiction to be a result of the Holder Representative’s own gross negligence or willful misconduct (as determined by final adjudication of a court of competent jurisdiction).

(f)   The Holder Representative hereby represents and warrants on behalf of itself to each STPC Party as of the date hereof and as of the Closing Date, as follows:

(i)   The Holder Representative has the requisite capacity, power and authority to execute and deliver this Agreement and each of the Ancillary Documents to which it is or will be a party, to perform his obligations hereunder and thereunder, and to consummate the transactions contemplated hereby and thereby.

(ii)   The execution and delivery of this Agreement, the Ancillary Documents to which the Holder Representative is or will be a party and the consummation of the transactions contemplated hereby and thereby have been (or, in the case of any Ancillary Document entered into after the date of this Agreement, will be upon execution thereof) duly authorized by all necessary action on the part of the Holder Representative. This Agreement and each Ancillary Document to which the Holder Representative is or will be a party has been or will be upon execution thereof, duly and validly executed and delivered by the Holder Representative and constitutes or will constitute, upon execution and delivery thereof, as applicable, a valid, legal and binding agreement of the Holder Representative, enforceable against the Holder Representative in accordance with their terms (subject to applicable bankruptcy, insolvency, reorganization, moratorium or other Laws affecting generally the enforcement of creditors’ rights and subject to general principles of equity).

(iii)   The Holder Representative has the sole power, authority and control of the Pre-Closing Holders with respect to the matters relating to this Agreement and the Ancillary Documents, including as contemplated in Section 8.20(a), and in general to do all other things and to perform all other acts, including executing and delivering all agreements, certificates, receipts, instructions, and other instruments, contemplated by, or deemed advisable in connection with, this Agreement or any Ancillary Document, in each case on behalf of a Pre-Closing Holder.

(g)   The Holder Representative shall execute an instrument in form and substantace reasonably satisfactory to STPC and the Company agreeing to bound by the terms of Section 2.6 and this Section 8.20; provided that the Parties agree that any provisions in this Section 8.20 may be amended to reflect any reasonable and customary comments by the Holder Representative once such Person has been appointed, and such Parties shall not unreasonably withhold consent to an amendment necessary to reflect any such comments.

Section 2.5Notice of Stockholders’ Meetings. Whenever stockholders are required or permitted to take any action at a meeting, a written notice of the meeting shall be given which shall state the place, date and hour of the meeting, the record date for determining the stockholders entitled to vote at the meeting, if such date is different from the record date for determining stockholders entitled to notice of the meeting, and, in the case of a special meeting, the purpose or purposes for which the meeting is called. Except as otherwise provided in the General Corporation Law of the State of the Delaware (the “DGCL”), the Certificate or these bylaws, the written notice of any meeting of stockholders shall be given not less than 10 nor more than 60 days before the date of the meeting to each stockholder entitled to vote at such meeting as of the record date for determining the stockholders entitled to notice of the meeting.

Section 2.6Quorum. The holders of a majority of the aggregate voting power of the capital stock issued and outstanding and entitled to vote, present in person or represented by proxy, shall constitute a quorum for the transaction of business at all meetings of the stockholders, except as otherwise required by the DGCL, the Certificate or these bylaws. Where a separate vote by a class or series or classes or series is required, a majority of the outstanding shares of such class or series or classes or series, present in person or represented by proxy, shall constitute a quorum (as to such class or series) entitled to take action with respect to that vote on that matter, except as otherwise provided by law, the Certificate or these bylaws. Abstentions and non-votes by brokers are counted as present for purposes of determining a quorum.

If a quorum is not present or represented at any meeting of the stockholders, then either (i) the chairperson of the meeting, or (ii) the holders of a majority of the shares entitled to vote at the meeting, present in person or represented by proxy, shall have power to adjourn the meeting from time to time, without notice other than announcement at the meeting, until a quorum is present or represented. At such adjourned meeting at which a quorum is present or represented, any business may be transacted that might have been transacted at the meeting as originally noticed.

Section 2.7Adjourned Meeting; Notice.   When a meeting is adjourned to another time and/or place, unless these bylaws otherwise require, notice need not be given of the adjourned meeting if the time and place thereof are announced at the meeting at which the adjournment is taken. At the adjourned meeting, the Corporation may transact any business which might have been transacted at the original meeting. If the adjournment is for more than 30 days or a new record date for stockholders entitled to vote is fixed for the adjourned meeting, a notice of the adjourned meeting shall be given to each stockholder of record entitled to vote at the meeting.

Section 2.8Conduct of Business.   The chairperson of any meeting of stockholders shall determine the order of business and the procedure at the meeting, including such regulation of the manner of voting and the conduct of business. The chairperson of any meeting of stockholders shall be designated by the Board; in the absence of such designation, the Chairman of the Board, if any, the Chief Executive Officer (in the absence of the chairperson) or the President (in the absence of the Chairman of the Board and the Chief Executive Officer), or in their absence any other executive officer of the Corporation, shall serve as chairperson of the stockholder meeting.

Section 2.9Voting.

(i)   Voting Rights. Except as may be otherwise provided by law, the Certificate or these bylaws, each stockholder shall be entitled to one vote for each share of capital stock held by such stockholder. Any share of capital stock of the Corporation held by the Corporation shall have no voting rights.

(ii)   Vote Required. Except as otherwise required by law, the Certificate or these bylaws, in all matters other than the election of directors, the affirmative vote of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote on the subject matter shall be the act of the stockholders. Except as otherwise required by law, the Certificate or these bylaws, the vote required for election of a director by the stockholders at a meeting of stockholders shall, except in a

Annex C-5

contested election, be the affirmative vote of a majority of the votes cast in favor or against the election of a nominee at a meeting of stockholders. In a contested election, the directors shall be elected by a plurality of the votes cast at a meeting of stockholders by the holders of stock entitled to vote in such election. For purposes of Section 2.9(ii), (i) a “contested election” means that as of the record date for the meeting at which the election is held, there are more nominees for election than positions on the Board of Directors and (ii) a “majority of the votes cast” means that the number of votes cast in favor of the election of a director exceeds the number of votes cast against the election of that director.

(iii)   Abstentions and Broker Non-Votes. In determining the number of votes cast for or against a proposal or nominee, shares abstaining from voting on a matter will not be treated as a vote cast. A non-vote by a broker will be counted for purposes of determining a quorum but not for purposes of determining the number of votes cast.

Section 2.10No Stockholder Action by Written Consent Without a Meeting. Subject to the rights of the holders of any series of preferred stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation and may not be effected by any consent in writing by such stockholders.

Section 2.11Record Dates.

(i)   In order that the Corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board and which record date shall not be more than 60 nor less than 10 days before the date of such meeting. If no record date is fixed by the Board, the record date for determining stockholders entitled to notice of and to vote at a meeting of stockholders shall be at the close of business on the day next preceding the day on which notice is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the Board may fix a new record date for determination of stockholders entitled to vote at the adjourned meeting.

(ii)   In order that the Corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the Board may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall be not more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the Board adopts the resolution relating thereto.

Section 2.12Proxies. Each stockholder entitled to vote at a meeting of stockholders may authorize another person or persons to act for such stockholder by proxy authorized by an instrument in writing or by a transmission permitted by law filed in accordance with the procedure established for the meeting, but no such proxy shall be voted or acted upon after three years from its date, unless the proxy provides for a longer period. The revocability of a proxy that states on its face that it is irrevocable shall be governed by the provisions of Section 212 of the DGCL. A written proxy may be in the form of a telegram, cablegram, or other means of electronic transmission permitted by law, which results in a writing from such stockholder or by his attorney and delivered to the Secretary of the meeting.

Section 2.13List of Stockholders Entitled to Vote. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least 10 days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting; provided, however, if the record date for determining the stockholders entitled to vote is less than 10 days before the meeting date, the list shall reflect the stockholders entitled to vote as of the tenth day before the meeting date. The stockholder list shall be arranged in alphabetical order and show the address of each stockholder and the number of shares registered in the name of each stockholder. The Corporation shall not be required to include electronic mail addresses or other

Annex C-6

electronic contact information on such list. Such list shall be open to the examination of any stockholder for any purpose germane to the meeting for a period of at least 10 days prior to the meeting (i) at a place within the city where the meeting is to be held, which place shall be specified in the notice of the meeting or (ii) during ordinary business hours at the Corporation’s principal place of business.

Any director may resign at any time upon notice given in writing or by electronic transmission to the Corporation; provided, however, that if such notice is given by electronic transmission, such electronic transmission must either set forth or be submitted with information from which it can be determined that the electronic transmission was authorized by the director. A resignation is effective when the resignation is delivered unless the resignation specifies a later effective date or an effective date determined upon the happening of an event or events. Acceptance of such resignation shall not be necessary to make it effective.

Vacancies and newly created directorships resulting from any increase in the authorized number of directors elected by all of the stockholders having the right to vote as a single class shall be filled only by a majority of the directors then in office, although less than a quorum, or by a sole remaining director.

A meeting at which a quorum is initially present may continue to transact business notwithstanding the withdrawal of directors, if any action taken is approved by at least a majority of the required quorum for that meeting. The vote of a majority of the directors present at any meeting at which a quorum is present shall be the act of the Board, except as may be otherwise specifically provided by statute, the Certificate or these bylaws.

Section 3.10Board Action by Written Consent Without a Meeting. Unless otherwise restricted by the Certificate or these bylaws, any action required or permitted to be taken at any meeting of the Board, or of any committee thereof, may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing or by electronic transmission and the writing or writings or electronic transmission or transmissions are filed with the minutes of proceedings of the Board or committee.

Without limiting the manner by which notice otherwise may be given effectively to stockholders pursuant to the DGCL, the Certificate or these bylaws, any notice to stockholders given by the Corporation under any provision of the DGCL, the Certificate or these bylaws shall be effective if given by a form of electronic transmission consented to by the stockholder to whom the notice is given. Any such consent shall be revocable by the stockholder by written notice to the Corporation. Any such consent shall be deemed revoked if:

(i)   the Corporation is unable to deliver by electronic transmission two consecutive notices given by the Corporation in accordance with such consent; and

(ii)   such inability becomes known to the Secretary or an Assistant Secretary of the Corporation or to the transfer agent, or other person responsible for the giving of notice.

However, the inadvertent failure to treat such inability as a revocation shall not invalidate any meeting or other action.

Any notice given pursuant to the preceding paragraph shall be deemed given:

(i)   if by facsimile telecommunication, when directed to a number at which the stockholder has consented to receive notice;

(ii)   if by electronic mail, when directed to an electronic mail address at which the stockholder has consented to receive notice;

(iii)   if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon the later of (A) such posting and (B) the giving of such separate notice; and

(iv)   if by any other form of electronic transmission, when directed to the stockholder.

An affidavit of the Secretary or an Assistant Secretary or of the transfer agent or other agent of the Corporation that the notice has been given by a form of electronic transmission shall, in the absence of fraud, be prima facie evidence of the facts stated therein.

Annex C-12

An “electronic transmission” means any form of communication, not directly involving the physical transmission of paper, that creates a record that may be retained, retrieved, and reviewed by a recipient thereof, and that may be directly reproduced in paper form by such a recipient through an automated process.

Section 7.3Notice to Stockholders Sharing an Address. Except as otherwise prohibited under the DGCL, without limiting the manner by which notice otherwise may be given effectively to stockholders, any notice to stockholders given by the Corporation under the provisions of the DGCL, the Certificate or these bylaws shall be effective if given by a single written notice to stockholders who share an address if consented to by the stockholders at that address to whom such notice is given. Any such consent shall be revocable by the stockholder by written notice to the Corporation. Any stockholder who fails to object in writing to the Corporation, within 60 days of having been given written notice by the Corporation of its intention to send the single notice, shall be deemed to have consented to receiving such single written notice.

Section 7.4Notice to Person with Whom Communication Is Unlawful. Whenever notice is required to be given under the DGCL, the Certificate or these bylaws, to any person with whom communication is unlawful, the giving of such notice to such person shall not be required and there shall be no duty to apply to any governmental authority or agency for a license or permit to give such notice to such person. Any action or meeting which shall be taken or held without notice to any such person with whom communication is unlawful shall have the same force and effect as if such notice had been duly given. In the event that the action taken by the Corporation is such as to require the filing of a certificate under the DGCL, the certificate shall state, if such is the fact and if notice is required, that notice was given to all persons entitled to receive notice except such persons with whom communication is unlawful.

Section 7.5Waiver of Notice. Whenever notice is required to be given to stockholders, directors or other persons under any provision of the DGCL, the Certificate or these bylaws, a written waiver, signed by the person entitled to notice, or a waiver by electronic transmission by the person entitled to notice, whether before or after the time of the event for which notice is to be given, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders or the Board, as the case may be, need be specified in any written waiver of notice or any waiver by electronic transmission unless so required by the Certificate or these bylaws.

Subject to the other provisions of this ARTICLE VIII, the Corporation shall indemnify and hold harmless, to the fullest extent permitted by the DGCL, as now or hereinafter in effect, any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit, arbitration, alternative dispute resolution mechanism, investigation, inquiry, judicial, administrative or legislative hearing, or any other threatened, pending or completed proceeding, whether civil, criminal, administrative, legislative, investigative or other nature and including any and all appeals (collectively, each a “Proceeding”) (other than an action by or in the right of the Corporation to procure a judgement in its favor) by reason of the fact that such person is or was a director or officer of the Corporation, or while a director of the Corporation or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against all liability and loss suffered and expenses, including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes, damages, claims, penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such Proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which such person reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that such person’s conduct was unlawful.

Annex C-13

Section 8.2Indemnification of Directors and Officers in Actions by or in the Right of the Corporation. Subject to the other provisions of this ARTICLE VIII, the Corporation shall indemnity, to the fullest extent permitted by the DGCL, as now or hereinafter in effect, any person who was or is a party or is threatened to be made a party to any Proceeding by or in the right of the Corporation to procure a judgement in its favor by reason of the fact that such person is or was a director or officer of the Corporation, or while a director or officer of the Corporation is or was serving at the request of the Corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against all liability and loss suffered and expenses, including, without limitation, attorneys’ fees, judgments, fines, ERISA excise taxes, damages, claims, penalties and amounts paid in settlement actually and reasonably incurred by such person in connection with such Proceeding, if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the Corporation; except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the Corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Section 8.3Successful Defense. To the extent that a present or former director or officer of the Corporation has been successful on the merits or otherwise in defense of any Proceeding described in Section 8.1 or Section 8.2, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith to the extent not already advanced pursuant to Section 8.5.

Expenses (including attorneys’ fees) incurred by an officer or director of the Corporation in defending any Proceeding shall be paid by the Corporation, and expenses (including attorneys’ fees) incurred by the Corporation’s employees and agents in defending any Proceeding shall be paid by the Corporation, in advance of the final disposition of such Proceeding upon receipt of a written request therefor and an undertaking, by or on behalf of the person, to repay such amounts so advanced if it shall ultimately be determined by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal that such person is not entitled to be indemnified under this ARTICLE VIII or the DGCL. The right to advancement of expenses shall not apply if a determination is reasonably made that the facts known at the time such determination is made demonstrate clearly and convincingly that officer, director, employee or agent, as applicable, acted in bad faith or in a manner that such person did not reasonably believe to be in or not opposed to the best interests of the Corporation, or, with respect to any criminal proceeding, that such person had reasonable cause to believe his or her conduct was unlawful. Such determination shall be made: (i) by the Board of Directors by a majority vote of directors who are not parties to such proceeding, whether or not such majority constitutes a quorum; (ii) by a committee of such directors designated by a majority vote of such directors, whether or not such majority constitutes a quorum; or (iii) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to the officer, director, employee or agent, as applicable.

(iii)   for any reimbursement of the Corporation by such person of any bonus or other incentive-based or equity-based compensation or of any profits realized by such person from the sale of securities of the Corporation, as required in each case under the 1934 Act (including any such reimbursements that arise from an accounting restatement of the Corporation pursuant to Section 304 of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”), or the payment to the Corporation of profits arising from the purchase and sale by such person of securities in violation of Section 306 of the Sarbanes-Oxley Act), if such person is held liable therefor (including pursuant to any settlement arrangements);

(iv)   initiated by such person (and not by way of defense), unless (a) the Board authorized the Proceeding (or the relevant part of the Proceeding) prior to its initiation, (b) the Corporation provides the indemnification, in its sole discretion, pursuant to the powers vested in the Corporation under applicable law, (c) otherwise required to be made under Section 8.6 or (d) otherwise required by applicable law; or

(v)   if prohibited by applicable law; provided, however, that if any provision or provisions of this ARTICLE VIII shall be held to be invalid, illegal or unenforceable for any reason whatsoever: (1) the validity, legality and enforceability of the remaining provisions of this ARTICLE VIII (including, without limitation, each portion of any paragraph or clause containing any such provision held to be invalid, illegal or unenforceable, that is not itself held to be invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby; and (2) to the fullest extent possible, the provisions of this ARTICLE VIII (including, without limitation, each such portion of any paragraph or clause containing any such provision held to be invalid, illegal or unenforceable) shall be construed so as to give effect to the intent manifested by the provision held invalid, illegal or unenforceable.

If a claim for indemnification or advancement of expenses under this ARTICLE VIII is not paid in full within 90 days after receipt by the Corporation of the written request therefor, the claimant shall be entitled to an adjudication by a court of competent jurisdiction of his or her entitlement to such indemnification or advancement of expenses. The Corporation shall indemnify such person against any and all expenses that are incurred by such person in connection with any action for indemnification or advancement of expenses from the Corporation under this ARTICLE VIII, to the extent such person is successful in such action, and to the extent not prohibited by law.

Annex D-4

(b) vote, express consent or dissent or issue instructions to the record holder to vote the Supporting Holders’ Subject Shares in accordance with the provisions of Section 1.1 at any and all meetings of the Supporting Holders or in connection with any action sought to be taken by written consent of the Supporting Holders without a meeting and (c) grant or withhold, or issue instructions to the record holder to grant or withhold, consistent with the provisions of Section 1.1, all written consents with respect to the Subject Shares at any and all meetings of the Supporting Holders or in connection with any action sought to be taken by written consent of the Supporting Holders without a meeting.

The foregoing proxy shall be deemed to be a proxy coupled with an interest, is irrevocable (and as such shall survive and not be affected by the death, incapacity, mental illness or insanity of any Supporting Holder, as applicable) until the termination of this Agreement pursuant to Section 5.2 and shall not be terminated by operation of Law or upon the occurrence of any other event other than the termination of this Agreement pursuant to Section 5.2. The Supporting Holders authorize such attorney and proxy to substitute any other Person to act hereunder, to revoke any substitution and to file this proxy and any substitution or revocation with the Secretary of STPC. The Supporting Holders hereby affirm that the proxy set forth in this Section 4.5 is given in connection with and granted in consideration of and as an inducement to STPC to enter into the Merger Agreement and that such proxy is given to secure the obligations of the Supporting Holders under Section 1.1. The proxy set forth in this Section 4.5 is executed and intended to be irrevocable, subject, however, to its automatic termination upon the termination of this Agreement pursuant to Section 5.2.

5.10   Severability.   Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

FORM OF SUBSCRIPTION AGREEMENT

Star Peak Corp II
1603 Orrington Avenue, 13th Floor
Evanston, IL 60201

Ladies and Gentlemen:

This Subscription Agreement (this “Subscription Agreement”) is being entered into as of the date set forth on the signature page hereto, by and between Star Peak Corp II, a Delaware corporation (“STPC”), and the undersigned subscriber (the “Investor”), in connection with the Agreement and Plan of Merger dated as of the date hereof (as may be amended, supplemented or otherwise modified from time to time, the “Merger Agreement”), by and among STPC, Benson Hill, Inc., a Delaware corporation (the “Company”), and STPC II Merger Sub Corp., a Delaware corporation (“Merger Sub”), pursuant to which, among other things, Merger Sub will merge with and into the Company, with the Company as the surviving company in the merger and, after giving effect to such merger, becoming a subsidiary of STPC, on the terms and subject to the conditions therein (the transactions contemplated by the Merger Agreement, including the merger, the “Transaction”). In connection with the Transaction, STPC is seeking commitments from interested investors to purchase, contingent upon, and substantially concurrently with the closing of the Transaction, shares of STPC’s Class A Common Stock, par value $0.0001 per share (the “Shares”), in a private placement for a purchase price of $10.00 per share (the “Per Share Purchase Price”). On or about the date of this Subscription Agreement, STPC is entering into subscription agreements (the “Other Subscription Agreements” and together with the Subscription Agreement, the “Subscription Agreements”) with certain other investors (the “Other Investors” and together with the Investor, the “Investors”), pursuant to which the Investors have, severally and not jointly, agreed to purchase on the closing date of the Transaction, inclusive of the Shares subscribed for by the Investor, an aggregate amount of up to 22,500,000 Shares, at the Per Share Purchase Price.

The aggregate purchase price to be paid by the Investor for the subscribed Shares (as set forth on the signature page hereto) is referred to herein as the “Subscription Amount.”

In connection therewith, and in consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, set forth herein, and intending to be legally bound hereby, each of the Investor and STPC acknowledges and agrees as follows:

1.   Subscription.   The Investor hereby irrevocably subscribes for and agrees to purchase from STPC, and STPC agrees to issue and sell to Investor, the number of Shares set forth on the signature page of this Subscription Agreement on the terms and subject to the conditions provided for herein.

2.   Closing.   The closing of the sale of the Shares contemplated hereby (the “Closing”) is contingent upon the substantially concurrent consummation of the Transaction. The Closing shall occur on the date of, and substantially concurrently with and conditioned upon the effectiveness of, the Transaction. Upon (a) satisfaction or waiver in writing of the conditions set forth in Section 3 below and (b) delivery of written notice from (or on behalf of) STPC to the Investor (the “Closing Notice”), that STPC reasonably expects all conditions to the closing of the Transaction to be satisfied or waived on a date that is not less than five (5) business days from the date on which the Closing Notice is delivered to the Investor, the Investor shall deliver to STPC, at least two (2) business days prior to the closing date specified in the Closing Notice (the “Closing Date”), (i) the Subscription Amount by wire transfer of United States dollars in immediately available funds to the account(s) specified by STPC in the Closing Notice to be held by STPC in escrow until the closing and (ii) any other information that is reasonably requested in the Closing Notice in order for STPC to issue the Investor’s Shares, including, without limitation, the legal name of the person (or nominee) in whose name such Shares are to be issued and a duly executed Internal Revenue Service Form W-9 or W-8, as applicable. On the Closing Date, STPC shall issue the number of Shares to the Investor set forth on the signature page to this Subscription Agreement and cause such Shares to be registered in book entry form in the name of the Investor (or its nominee in accordance with its delivery instructions) on STPC’s share register or, as soon as practicable thereafter, provide a copy of the records of STPC’s transfer agent

Annex E-1

showing the Investor (or such nominee or custodian) as the owner of the Shares on and as of the Closing Date; provided, however, that STPC’s obligation to issue the Shares to the Investor is contingent upon STPC having received the Subscription Amount in full accordance with this Section 2. If the Closing does not occur within five (5) business days following the Closing Date specified in the Closing Notice, STPC shall promptly (but not later than one (1) business day thereafter) return the Subscription Amount in full to the Investor by wire transfer in immediately available funds to the account specified by the Investor. For purposes of this Subscription Agreement, “business day” shall mean a day other than a Saturday, Sunday or other day on which commercial banks in New York, New York are authorized or required by law to close.

3.   Closing Conditions.

a.   The obligation of the parties hereto to consummate the purchase and sale of the Shares pursuant to this Subscription Agreement is subject to the following conditions:

(i)   no applicable 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 contemplated hereby;

(ii)   all conditions precedent to the closing of the Transaction under the Merger Agreement shall have been satisfied (as determined by the parties to the Merger Agreement and other than those conditions under the Merger Agreement which, by their nature, are to be fulfilled at the closing of the Transaction, including to the extent that any such condition is dependent upon the consummation of the purchase and sale of the Shares pursuant to this Subscription Agreement) or waived and the closing of the Transaction shall be scheduled to occur concurrently with or on the same date as the Closing Date; and

(iii)   no suspension of the offering or sale of the Shares in any jurisdiction shall have occurred or been initiated or, to STPC’s knowledge, threatened by the Securities and Exchange Commission (the “SEC”).

b.   The obligation of STPC to consummate the issuance and sale of the Shares pursuant to this Subscription Agreement shall be subject to the conditions that (i) all representations and warranties of the Investor contained in this Subscription Agreement are true and correct in all material respects at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by the Investor of each of the representations and warranties of the Investor contained in this Subscription Agreement as of the Closing Date and (ii) all obligations, covenants and agreements of the Investor required to be performed by it at or prior to the Closing Date shall have been performed in all material respects.

c.   The obligation of the Investor to consummate the purchase of the Shares pursuant to this Subscription Agreement shall be subject to the conditions that (i) all representations and warranties of STPC contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect (as defined herein), which representations and warranties shall be true in all respects) at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by STPC of each of the representations and warranties of STPC contained in this Subscription Agreement as of the Closing Date, (ii) all obligations, covenants and agreements of STPC required by the Subscription Agreement to be performed by it at or prior to the Closing Date shall have been performed in all material respects and (iii) there shall have been no amendments or modifications to the Merger Agreement (as the same exists on the date of this Subscription Agreement) that would reasonably be expected to, in the aggregate, materially and adversely affect the economic benefits that the Investor would reasonably expect to receive under this Subscription Agreement, unless the Investor has consented in writing to such amendments or modifications.

4.   Further Assurances.   At or prior to the Closing Date, the parties hereto shall execute and deliver or cause to be executed and delivered such additional documents and take such additional actions as the

Annex E-2

parties reasonably may deem to be practical and necessary in order to consummate the subscription as contemplated by this Subscription Agreement.

5.   STPC Representations and Warranties.   STPC represents and warrants to the Investor and each of the Placement Agents (as defined below) that:

a.   STPC has been duly formed as a Delaware corporation and is validly existing and in good standing under the laws of the State of Delaware, with corporate power and authority to own, lease and operate its properties and conduct its business as presently conducted and to enter into, deliver and perform its obligations under this Subscription Agreement.

b.   As of the Closing Date, the Shares will be duly authorized and, when issued and delivered to the Investor against full payment therefor in accordance with the terms of this Subscription Agreement, the Shares will be validly issued, fully paid and non-assessable, free and clear of any liens or other restrictions (other than those under applicable securities laws), and will not have been issued in violation of or subject to any preemptive or similar rights created under STPC’s certificate of incorporation or bylaws (each as amended to the Closing Date) or the Delaware General Corporation Law.

c.   This Subscription Agreement has been duly authorized, executed and delivered by STPC and, assuming that this Subscription Agreement constitutes the valid and binding agreement of the Investor, this Subscription Agreement is enforceable against STPC in accordance with its terms, except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally, or (ii) principles of equity, whether considered at law or equity.

d.   The execution and delivery of this Subscription Agreement and the issuance and sale of the Shares and the compliance by STPC with all of the provisions of this Subscription Agreement and the consummation of the transactions contemplated herein will not: (i) 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 STPC or any of its subsidiaries pursuant to the terms of any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement or instrument to which STPC or any of its subsidiaries is a party or by which STPC or any of its subsidiaries is bound or to which any of the property or assets of STPC is subject that would reasonably be expected to have a material adverse effect on the business, financial condition or results of operations of STPC and its subsidiaries, taken as a whole (a “Material Adverse Effect”), or materially affect the validity of the Shares or the legal authority of STPC to timely comply in all material respects with the terms of this Subscription Agreement; (ii) result in any violation of the provisions of the organizational documents of STPC; or (iii) result in any violation of any statute or any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over STPC or any of its properties that would reasonably be expected to have a Material Adverse Effect or materially affect the validity of the Shares or the legal authority of STPC to timely comply in all material respects with this Subscription Agreement. As of the date hereof, STPC has not received any written communication from a governmental entity that alleges that STPC 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, be reasonably likely to have a Material Adverse Effect.

e.   As of their respective dates, all reports, as amended (the “SEC Reports”), required to be filed by STPC with the SEC complied in all material respects with the applicable requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and regulations of the SEC promulgated thereunder, and none of the SEC Reports, when filed, contained any untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The financial statements of STPC included in the SEC Reports comply in all material respects with applicable accounting requirements and the rules and regulations of the SEC with respect thereto as in effect at the time of filing and fairly present in all material respects the financial position of STPC as of and for the dates thereof and the results of operations and cash flows for the periods then ended, subject, in the case of

Annex E-3

unaudited statements, to normal, year-end audit adjustments. To the knowledge of STPC, there are no outstanding or unresolved comments in comment letters received by STPC from the staff of the Division of Corporation Finance of the SEC with respect to any of the SEC Reports as of the date hereof. Notwithstanding anything to the contrary in this Subscription Agreement, no representation or warranty is made as to the accounting treatment of STPC’s issued and outstanding warrants, or as to any deficiencies in disclosure (including with respect to accounting and disclosure controls) arising from the accounting treatment of such warrants, in any SEC Reports.

f.   Assuming the accuracy of the Investor’s representations and warranties set forth in Section 6, no registration under the Securities Act is required for the offer and sale of the Shares by STPC to the Investor hereunder. The Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state securities laws.

g.   STPC 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 or other person in connection with the execution, delivery and performance by STPC of this Subscription Agreement (including, without limitation, the issuance of the Shares), other than: (i) filings with the SEC; (ii) filings required by applicable state securities laws, (iii) filings required in accordance with Section 13 of this Subscription Agreement; (iv) those required by the New York Stock Exchange (“NYSE”), including with respect to obtaining approval of STPC’s stockholders; and (v) any filing the failure of which to obtain would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect.

h.   As of the date of this Subscription Agreement, the authorized capital stock of STPC consists of (i) 1,000,000 shares of preferred stock, par value $0.0001 per share (“Preferred Stock”), and (ii) 440,000,000 shares of common stock, par value $0.0001 per share (the “Common Stock”), including (1) 400,000,000 shares of Class A Common Stock, par value $0.0001 per share (“Class A Shares”), and (2) 40,000,000 shares of Class B Common Stock, par value $0.0001 per share (“Class B Shares”).

i.   Other than the Other Subscription Agreements, STPC has not entered into any side letter or similar agreement with any Other Investor or other person in connection with such Other Investor’s or person’s direct or indirect investment in STPC (other than any side letter or similar agreement relating to the transfer to any investor of (i) securities of STPC by existing securityholders of STPC, which may be effectuated as a forfeiture to STPC and reissuance, or (ii) securities to be issued to the direct or indirect securityholders of the Company pursuant to the Merger Agreement). No Other Subscription Agreement includes terms and conditions that are more advantageous to any such Other Investor than the Investor hereunder, and such Other Subscription Agreements have not been amended or modified in any material respect following the date of this Subscription Agreement.

j.   As of the date hereof, the issued and outstanding Class A Shares are registered pursuant to Section 12(b) of the Exchange Act, and are listed for trading on the NYSE, under the symbol “STPC”

STPC has taken no action that is designed to terminate the registration of the Class A Shares under the Exchange Act. At Closing, the Shares will be listed for trading on the NYSE or another national securities exchange.

k.   Except for such matters as have not had and would not be reasonably likely to have, individually or in the aggregate, a Material Adverse Effect, as of the date hereof, there is no (i) investigation, action, suit, claim or other proceeding, in each case by or before any governmental authority, pending, or, to the knowledge of STPC, threatened against STPC or (ii) judgment, decree, injunction, ruling or order of any governmental entity outstanding against STPC.

l.   STPC is not under any obligation to pay any broker’s fee or commission in connection with the sale of the Shares hereunder other than to the Placement Agents.

n.   Other than as set forth in the Merger Agreement or any SEC Report, there are no securities or instruments issued by or to which STPC is a party containing anti-dilution or similar provisions that will be triggered by the issuance of (i) the Shares or (ii) the shares to be issued pursuant to any Other Subscription Agreement that have not been or will not be validly waived on or prior to the Closing Date.

6.   Investor Representations and Warranties.   The Investor represents and warrants to STPC and each of the Placement Agents (as defined below) that:

a.   The Investor, or each of the funds managed by or affiliated with the Investor for which the Investor is acting as nominee, as applicable, (i) is a “qualified institutional buyer” ​(as defined in Rule 144A under the Securities Act), or an institutional “accredited investor” ​(within the meaning of Rule 501(a) under the Securities Act), in each case, satisfying the applicable requirements set forth on Schedule A, (ii) is acquiring the Shares only for its own account and not for the account of others, or if the Investor is subscribing for the Shares as a fiduciary or agent for one or more investor accounts, the Investor has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgments, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring the Shares with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act (and shall provide the requested information set forth on Schedule A).

b.   The Investor acknowledges and agrees that the Shares are being offered in a transaction not involving any public offering within the meaning of the Securities Act and that the Shares have not been registered under the Securities Act. The Investor acknowledges and agrees that the Shares may not be offered, resold, transferred, pledged or otherwise disposed of by the Investor absent an effective registration statement under the Securities Act except (i) to STPC or a subsidiary thereof, (ii) to non-U.S. persons pursuant to offers and sales that occur outside the United States within the meaning of Regulation S under the Securities Act or (iii) pursuant to another applicable exemption from the registration requirements of the Securities Act, and in each of clauses (i) and (iii) in accordance with any applicable securities laws of the states and other jurisdictions of the United States, and that any certificates representing the Shares shall contain a restrictive legend to such effect.

The Investor acknowledges and agrees that the Shares will not be eligible for offer, resale, transfer, pledge or disposition pursuant to Rule 144 promulgated under the Securities Act (“Rule 144”) until at least one year from the Closing Date. The Investor acknowledges and agrees that it has been advised to consult legal counsel and tax and accounting advisors prior to making any offer, resale, transfer, pledge or disposition of any of the Shares.

Annex E-5

c.   The Investor acknowledges and agrees that the Investor is purchasing the Shares directly from STPC. The Investor further acknowledges that there have been no representations, warranties, covenants and agreements made to the Investor by or on behalf of STPC, the Company, any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing or any other person or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of STPC expressly set forth in Section 5 of this Subscription Agreement.

d.   The Investor acknowledges and is aware that Barclays Capital Inc. (“Barclays”) is acting as financial advisor and capital markets advisor to the Company in connection with the Transaction and the Investor hereby waives any claims it may have based on any actual or potential conflict of interest or similar claim relating to or arising from Barclays acting as financial advisor and capital markets advisor to Company and acting as a placement agent to STPC.

e.   The Investor’s acquisition and holding of the Shares will not constitute or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended, Section 4975 of the Internal Revenue Code of 1986, as amended, or any applicable similar law.

f.   The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an investment decision with respect to the Shares, including, with respect to STPC, the Transaction and the business of the Company and its subsidiaries. Without limiting the generality of the foregoing, the Investor acknowledges that it has reviewed STPC’s filings with the SEC. The Investor acknowledges and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Investor and such Investor’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the Shares.

g.   The Investor became aware of this offering of the Shares solely by means of direct contact between the Investor and STPC, the Company or a representative of STPC or the Company, and the Shares were offered to the Investor solely by direct contact between the Investor and STPC, the Company or a representative of STPC or the Company. The Investor did not become aware of this offering of the Shares, nor were the Shares offered to the Investor, by any other means. The Investor acknowledges that the Shares (i) were not offered to it by any form of general advertising or, to its knowledge, general solicitation, and (ii) are not being offered to it in a manner involving a public offering under, or in a distribution in violation of, the Securities Act, or any state securities laws.

LLC, Barclays, Credit Suisse Securities (USA) LLC (collectively, the “Placement Agents”), STPC and the Company or any of their respective affiliates, or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), other than the representations and warranties of STPC contained in Section 5 of this Subscription Agreement, in making its investment or decision to invest in STPC.

h.   The Investor acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Shares, including those set forth in STPC’s filings with the SEC. The Investor has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Shares, and the Investor has sought such accounting, legal and tax advice as the Investor has considered necessary to make an informed investment decision and the Investor has made its own assessment and has satisfied itself concerning relevant tax and other economic considerations relative to its purchase of the Shares. The Investor will not look to the Placement Agents for all or part of any such loss or losses the Investor may suffer, is able to sustain a complete loss on its investment in the Shares, has no need for liquidity with respect to its investment in the Shares and has no reason to anticipate any change in circumstances, financial or otherwise, which may cause or require any sale or distribution of all or any part of the Shares.

i.   Alone, or together with any professional advisor(s), the Investor has adequately analyzed and fully considered the risks of an investment in the Shares and determined that the Shares are a suitable

Annex E-6

investment for the Investor and that the Investor is able at this time and in the foreseeable future to bear the economic risk of a total loss of the Investor’s investment in STPC. The Investor acknowledges specifically that a possibility of total loss exists.

j.   In making its decision to purchase the Shares, the Investor has relied solely upon independent investigation made by the Investor. Without limiting the generality of the foregoing, the Investor has not relied on any statements or other information provided by or on behalf of either the Placement Agents or any of their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing concerning STPC, the Company, the Transaction, the Merger Agreement, this Subscription Agreement or the transactions contemplated hereby or thereby, the Shares or the offer and sale of the Shares.

k.   The Investor acknowledges that the Placement Agents (i) have not provided the Investor with any information or advice with respect to the Shares, (ii) have not made or make any representation, express or implied as to STPC, the Company, the Company’s credit quality, the Shares or the Investor’s purchase of the Shares, (iii) have not acted as the Investor’s financial advisor or fiduciary in connection with the issue and purchase of Shares, (iv) may have acquired, or during the term of the Shares may acquire, non-public information with respect to the Company, which, subject to the requirements of applicable law, the Investor agrees need not be provided to it, and (v) may have existing or future business relationships with STPC and the Company (including, but not limited to, lending, depository, risk management, advisory and banking relationships) and will pursue actions and take steps that it deems or they deem necessary or appropriate to protect its or their interests arising therefrom without regard to the consequences for a holder of Shares, and that certain of these actions may have material and adverse consequences for a holder of Shares.

l.   The Investor acknowledges that it has not relied on the Placement Agents in connection with its determination as to the legality of its acquisition of the Shares or as to the other matters referred to herein and the Investor has not relied on any investigation that the Placement Agents, any of their affiliates or any person acting on their behalf have conducted with respect to the Shares, STPC or the Company. The Investor further acknowledges that it has not relied on any information contained in any research reports prepared by the Placement Agents or any of their affiliates.

m.   The Investor acknowledges and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the Shares or made any findings or determination as to the fairness of this investment.

n.   The Investor has been duly formed or incorporated and is validly existing and is in good standing under the laws of its jurisdiction of formation or incorporation, with power and authority to enter into, deliver and perform its obligations under this Subscription Agreement.

o.   The execution, delivery and performance by the Investor of this Subscription Agreement are within the powers of the Investor, have been duly authorized and will not constitute or result in a breach or default under or conflict with any order, ruling or regulation of any court or other tribunal or of any governmental commission or agency, or any agreement or other undertaking, to which the Investor is a party or by which the Investor is bound, and will not violate any provisions of the Investor’s organizational documents, including, without limitation, its incorporation or formation papers, bylaws, indenture of trust or partnership or operating agreement, as may be applicable. The signature on this Subscription Agreement is genuine, and the signatory has been duly authorized to execute the same, and, assuming that this Subscription Agreement constitutes the valid and binding obligation of STPC, this Subscription Agreement constitutes a legal, valid and binding obligation of the Investor, enforceable against the Investor in accordance with its terms except as may be limited or otherwise affected by (i) bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium or other laws relating to or affecting the rights of creditors generally and (ii) principles of equity, whether considered at law or equity.

p.   The Investor is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued by the President of the United States and administered

The Investor agrees to provide law enforcement agencies, if requested thereby, such records as required by applicable law, provided that the Investor is permitted to do so under applicable law. If the Investor is a financial institution subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.) (the “BSA”), as amended by the USA PATRIOT Act of 2001 (the “PATRIOT Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”), the Investor maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. To the extent required, it maintains policies and procedures reasonably designed to ensure compliance with OFAC-administered sanctions programs, including for the screening of its investors against the OFAC sanctions programs, including the OFAC List. To the extent required by applicable law, the Investor maintains policies and procedures reasonably designed to ensure that the funds held by the Investor and used to purchase the Shares were legally derived and were not obtained, directly or indirectly, from a Prohibited Investor.

q.   No disclosure or offering document has been prepared by the Placement Agents or any of their respective affiliates in connection with the offer and sale of the Shares.

r.   None of the Placement Agent, nor any of their respective affiliates nor any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing have made any independent investigation with respect to STPC, the Company or its subsidiaries or any of their respective businesses, or the Shares or the accuracy, completeness or adequacy of any information supplied to the Investor by STPC.

s.   In connection with the issue and purchase of the Shares, none of the Placement Agents have acted as the Investor’s financial advisor or fiduciary.

t.   The Investor has and, when required to deliver payment to STPC pursuant to Section 2 above, will have, sufficient funds to pay the Subscription Amount and consummate the purchase and sale of the Shares pursuant to this Subscription Agreement.

7.   Registration Rights

a.   In the event that the Shares are not registered in connection with the consummation of the Transaction, STPC agrees that, prior to the Closing Date, it will file with the SEC (at its sole cost and expense) a registration statement registering the resale of the Shares (the “Registration Statement”), and it shall use its commercially reasonable efforts to have the Registration Statement declared effective within three (3) business days after the Closing Date, or as soon as practicable thereafter, but no later than the earlier of (i) sixty (60) calendar days after the Closing Date (or ninety (90) calendar days after the Closing Date if the SEC notifies STPC that it will “review” the Registration Statement) and (ii) ten (10) business days after STPC is notified (orally or in writing, whichever is earlier) by the SEC that the Registration Statement will not be “reviewed” or will not be subject to further review. STPC will provide a draft of the Registration Statement to the undersigned for review at least two (2) business days in advance of filing the Registration Statement. In no event shall the undersigned be identified as a statutory underwriter in the Registration Statement unless requested by the SEC; provided that, if the SEC requests that the undersigned be identified as a statutory underwriter in the Registration Statement, the undersigned will have an opportunity to withdraw from the Registration Statement. Notwithstanding the foregoing, if the SEC prevents STPC 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 under the Securities Act for the resale of the Shares by the applicable stockholders or otherwise, such

Annex E-8

Registration Statement shall register for resale such number of Shares which is equal to the maximum number of Shares as is permitted by the SEC. In such event, the number of Shares to be registered for each selling shareholder named in the Registration Statement shall be reduced pro rata among all such selling shareholders, and as promptly as practicable after being permitted to register additional shares under Rule 415 under the Securities Act, STPC shall file a new Registration Statement to register such shares not included in the initial Registration Statement and cause such Registration Statement to become effective as promptly as practicable consistent with the terms of this Section 7. STPC agrees to cause such Registration Statement, or another shelf registration statement that includes the Shares to be issued pursuant to this Subscription Agreement, to remain effective until the earliest of (i) the third anniversary of the Closing, (ii) the date on which the Investor ceases to hold any Shares issued pursuant to this Subscription Agreement, or (iii) the first date on which the Investor is able to sell all of its Shares issued pursuant to this Subscription Agreement (or shares received in exchange therefor) under Rule 144 within 90 days without being subject to the public information, volume or manner of sale limitations of such rule (such date, the “End Date”). Prior to the End Date, STPC will use commercially reasonable efforts to qualify the Shares for listing on the applicable stock exchange. The Investor agrees to disclose its ownership to STPC upon request to assist it in making the determination with respect to Rule 144 described in clause (iii) above. STPC may amend the Registration Statement so as to convert the Registration Statement to a Registration Statement on Form S-3 at such time after STPC becomes eligible to use such Form S-3. STPC’s obligations to include the Shares issued pursuant to this Subscription Agreement (or shares issued in exchange therefor) for resale in the Registration Statement are contingent upon the Investor furnishing in writing to STPC such information regarding the Investor, the securities of STPC held by the Investor and the intended method of disposition of such Shares, which shall be limited to non-underwritten public offerings, as shall be reasonably requested by STPC to effect the registration of such Shares, and shall execute such documents in connection with such registration as STPC may reasonably request that are customary of a selling stockholder in similar situations. In connection with the foregoing, Investor shall not be required to execute any lock-up or similar agreement or otherwise be subject to any contractual restriction on the ability to transfer the Shares. For purposes of this Section 7, “Shares” shall mean, as of any date of determination, the Shares acquired by Investor pursuant to this Subscription Agreement and any other equity security issued or issuable with respect to such Shares by way of stock split, dividend, distribution, recapitalization, merger, exchange, replacement or similar event, and “Investor” shall include any person to whom rights under this Section 7 have been properly assigned in accordance with the terms of this Subscription Agreement.

b.   In the case of the registration, qualification, exemption or compliance effected by STPC pursuant to this Subscription Agreement, STPC shall, upon reasonable request, inform Investor as to the status of such registration, qualification, exemption and compliance. STPC shall, at its expense, prior to the End Date, advise the Investor within five (5) business days: (i) when a Registration Statement or any post-effective amendment thereto has become effective; (ii) of any request by the SEC for amendments or supplements to any Registration Statement or the prospectus included therein or for additional information; (iii) of the issuance by the SEC of any stop order suspending the effectiveness of any Registration Statement or the initiation of any proceedings for such purpose; (iv) of the receipt by STPC of any notification with respect to the suspension of the qualification of the Shares included therein for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; and (v) subject to the provisions in this Subscription Agreement, of the occurrence of any event that requires the making of any changes in any Registration Statement or prospectus so that, as of such date, the statements therein are not misleading and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (in the case of a prospectus, in the light of the circumstances under which they were made) not misleading (provided that any such notice pursuant to this Section 7(b) shall solely provide that the use of the Registration Statement or prospectus has been suspended without setting forth the reason for such suspension). STPC shall use its commercially reasonable efforts to obtain the withdrawal of any order suspending the effectiveness of any Registration Statement as soon as reasonably practicable. Upon the occurrence of any event contemplated in clauses (i) through (v) above, except for such times as STPC is permitted hereunder to suspend, and has suspended, the use of a prospectus forming part of a registration statement, STPC shall use its commercially reasonable efforts to prepare as soon as reasonably practicable a post-effective amendment

Annex E-9

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 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 the light of the circumstances under which they were made, not misleading. The Investor agrees that it will immediately discontinue offers and sales of the Shares using a Registration Statement until the Investor receives copies of a supplemental or amended prospectus that corrects the misstatement(s) or omission(s) referred to above in clause (v) and receives notice that any post-effective amendment has become effective or unless otherwise notified by STPC that it may resume such offers and sales. If so directed by STPC, the Investor will deliver to STPC or, in the Investor’s sole discretion, destroy all copies of the prospectus covering the Shares in the Investor’s possession; provided, however, that this obligation to deliver or destroy all copies of the prospectus covering the Shares shall not apply (x) to the extent the Investor is required to retain a copy of such prospectus in order to comply with applicable legal, regulatory, self-regulatory or professional requirements or in accordance with a bona fide pre-existing document retention policy or (y) to copies stored electronically on archival servers as a result of automatic data back-up. Notwithstanding anything to the contrary set forth herein, STPC shall not, when so advising the Investor of such events, provide the Investor with any material, nonpublic information regarding STPC other than to the extent that providing notice to the Investor of the occurrence of the events listed in (i) through (v) above constitutes material, nonpublic information regarding STPC; the Investor hereby consents to the receipt of any material, nonpublic information with respect to the occurrence of the events listed in (i) through (v) above.

c.   With a view to making available to the Investor the benefits of Rule 144 that may, at such times as Rule 144 is available to shareholders of the Company, permit the Investors to sell securities of the Company to the public without registration, STPC agrees to: (i)   make and keep public information available, as those terms are understood and defined in Rule 144; (ii) file with the SEC in a timely manner all reports and other documents required of STPC under the Securities Act and the Exchange Act so long as STPC remains subject to such requirements and the filing of such reports and other documents is required for the applicable provisions of Rule 144; and (iii) furnish to the Investor so long as such Investor owns the Shares acquired hereunder, within two (2) business days following its receipt of a written request therefor, (A) a written statement by STPC, if true, that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act, (B) a copy of the most recent annual or quarterly report of STPC and such other reports and documents so filed by STPC (it being understood that the availability of such reports on the SEC’s EDGAR system shall satisfy this requirement) and (C) such other information as may be reasonably requested in writing to permit the Investor to sell such securities pursuant to Rule 144 without registration.

d.   The Investor acknowledges and agrees that STPC may suspend the use of any such registration statement if it determines that in order for such registration statement not to contain a material misstatement or omission, an amendment thereto would be needed to include information that would at that time not otherwise be required in a current, quarterly, or annual report under the Exchange Act, provided, that, (I) STPC shall not so delay filing or so suspend the use of the Registration Statement on more than two occasions or for a period of more than ninety (90) consecutive days or more than a total of one hundred twenty (120) calendar days in any three hundred sixty (360) day period and (II) STPC shall use commercially reasonable efforts to make such Registration Statement available for the sale by the Investor of such securities as soon as practicable thereafter.

e.   STPC shall remove any restrictive legend included on the certificates (or, in the case of book-entry shares, any other instrument or record) representing the Investor’s ownership of Shares, and STPC shall issue a certificate (or evidence of the issuance of such securities in book-entry form) without such restrictive legend or any other restrictive legend to the Investor, if (i) such Shares are registered for resale under the Securities Act and the applicable registration statement has not been suspended pursuant to the Securities Act, the Exchange Act or the rules and regulations of the SEC promulgated thereunder, (ii) such Shares are sold or transferred pursuant to Rule 144, or (iii) such Shares are eligible for sale pursuant to Section 4(a)(1) of the Securities Act or Rule 144 without volume or manner-of-sale restrictions. Following the earlier of (A) the later of the Closing Date and the effective date of the registration statement registering such Shares or (B) Rule 144 becoming available for the resale of such

Annex E-10

Shares without volume or manner-of-sale restrictions, STPC, upon the written request of Investor (and no later than three (3) business days following such request), shall instruct STPC’s transfer agent to remove the legend from such Shares (in whatever form) and shall cause STPC’s counsel to issue any legend removal opinion required by the transfer agent.

f.   STPC shall, notwithstanding any termination of this Subscription Agreement, indemnify, defend and hold harmless Investor (to the extent a seller under the Registration Statement), the officers, directors, trustees, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of each of them, each person who controls Investor (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) and the officers, directors, trustees, agents, partners, members, managers, stockholders, affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon any untrue or alleged untrue statement of a material fact contained in the Registration Statement, any prospectus included in the Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, except insofar as the same are caused by or contained in any information furnished in writing to STPC by or on behalf of the Investor expressly for use therein.

g.   Investor shall, severally and not jointly with any Other Investor, indemnify and hold harmless STPC, its directors, officers, agents and employees, each person who controls STPC (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by applicable law, from and against all Losses, as incurred, arising out of or are based upon any untrue or alleged untrue statement of a material fact contained in any Registration Statement, any prospectus included in the Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent, that such untrue statements or omissions are based solely upon information regarding Investor furnished in writing to STPC by Investor expressly for use therein. In no event shall the liability of Investor be greater in amount than the dollar amount of the net proceeds received by Investor upon the sale of the Shares giving rise to such indemnification obligation. Notwithstanding the forgoing, Investor’s indemnification obligations shall not apply to amounts paid in settlement of any Losses or action if such settlement is effected without the prior written consent of Investor.

8.   Additional Investor Agreement.   The Investor hereby agrees that, from the date of this Subscription Agreement, none of Investor, its controlled affiliates, or any person or entity acting on behalf of Investor or any of its controlled affiliates or pursuant to any understanding with Investor or any of its controlled affiliates will engage in any Short Sales with respect to securities of STPC prior to the Closing. For purposes of this Section 8, “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage arrangements). Notwithstanding the foregoing, (i) nothing herein shall prohibit other entities under common management with the Investor that have no knowledge of this Subscription Agreement or of the Investor’s participation in the Transaction (including the Investor’s controlled affiliates and/or affiliates) from entering into any Short Sales, (ii) in the case of an Investor that is a multi-managed investment vehicle whereby separate portfolio managers manage separate portions of such Investor’s assets and the portfolio managers have no knowledge of the investment decisions made by the portfolio managers managing other portions of such Investor’s assets, this Section 8 shall only apply with respect to the portion of assets managed by the portfolio manager that made the investment decision to purchase the Subscription Amount covered by this Subscription Agreement and (iii) nothing herein shall prohibit the Investor from engaging in derivative transactions of any kind,

Annex E-11

including, but not limited to, forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through U.S. broker dealers or non-U.S. broker dealers or foreign regulated brokers. For the avoidance of doubt, this Section 8 shall not apply to ordinary course, non-speculative hedging transactions that would not, directly or indirectly, involve securities of STPC. STPC acknowledges and agrees that, notwithstanding anything herein to the contrary, the Shares may be pledged by Investor in connection with a bona fide margin agreement, which shall not be deemed to be a transfer, sale or assignment of the Shares hereunder, provided such pledge shall be (i) pursuant to an available exemption from the registration requirements of the Securities Act or (ii) pursuant to, and in accordance with, a registration statement that is effective under the Securities Act at the time of such pledge, and Investor effecting a pledge of Shares shall not be required to provide STPC with any notice thereof; provided, however, that neither STPC or their counsel shall be required to take any action (or refrain from taking any action) in connection with any such pledge, other than providing any such lender of such margin agreement with an acknowledgment that the Shares are not subject to any contractual prohibition on pledging or lock up, the form of such acknowledgment to be subject to review and comment by STPC in all respects.

9.   Termination.   This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to occur of (a) such date and time as the Merger Agreement is terminated in accordance with its terms without being consummated, (b) the mutual written agreement of each of the parties hereto to terminate this Subscription Agreement, (c) 30 days after the Termination Date (as defined in the Merger Agreement as the same exists on the date hereof and without regard to any extension thereto), if the Closing has not occurred by such date other than as a result of a breach of Investor’s obligations hereunder, or (d) if any of the conditions to Closing set forth in Section 3 of this Subscription Agreement are (i) not satisfied or waived prior to the Closing or (ii) not capable of being satisfied on the Closing and, in the case of each of (i) and (ii), as a result thereof, the transactions contemplated by this Subscription Agreement will not be and are not consummated at the Closing (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, and each party will be entitled to any remedies at law or in equity to recover losses, liabilities or damages arising from any such willful breach. STPC shall notify the Investor in writing of the termination of the Merger Agreement promptly after the termination of such agreement. Upon the occurrence of any Termination Event, this Subscription Agreement shall be void and of no further effect and any monies paid by the Investor to STPC in connection herewith shall promptly (and in any event within one (1) business day) following the Termination Event be returned to the Investor.

10.   Trust Account Waiver.   The Investor acknowledges that STPC is a blank check company with the powers and privileges to effect a merger, asset acquisition, reorganization or similar business combination involving STPC and one or more businesses or assets. The Investor further acknowledges that, as described in STPC’s prospectus relating to its initial public offering dated January 5, 2021 (the “Prospectus”) available at www.sec.gov, substantially all of STPC’s assets consist of the cash proceeds of STPC’s initial public offering and private placement of its securities, and substantially all of those proceeds have been deposited in a trust account (the “Trust Account”) for the benefit of STPC, its public shareholders and the underwriters of STPC’s initial public offering.

EACH OF THE PARTIES HERETO AND ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY MAY DO SO ONLY IF HE, SHE OR IT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY AND FOR ANY COUNTERCLAIM RELATING THERETO. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS PROHIBITED, NO PARTY HERETO NOR ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS SUBSCRIPTION AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY. FURTHERMORE, NO PARTY HERETO NOR ANY PERSON ASSERTING RIGHTS AS A THIRD PARTY BENEFICIARY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER LEGAL PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED.

The Investor acknowledges and agrees that none of (i) any Other Investor pursuant to the Other Subscription Agreements (including such Other Investor’s affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing), (ii) the Placement Agents, their respective affiliates or any control persons, officers, directors, employees, partners, agents or representatives of any of the foregoing, or (iii) any Non-Party Affiliate, shall have any liability to the Investor, or to any Other Investor, pursuant to, arising out of or relating to this Subscription Agreement or any Other Subscription Agreement, the negotiation hereof or thereof or its subject matter, or the transactions contemplated hereby or thereby, including, without limitation, with respect to any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the purchase of the Shares or with respect to any claim (whether in tort, contract or otherwise) for breach

Annex E-15

of this Subscription Agreement or in respect of any written or oral representations made or alleged to be made in connection herewith, as expressly provided herein, or for any actual or alleged inaccuracies, misstatements or omissions with respect to any information or materials of any kind furnished by STPC, the Company, the Placement Agents or any Non-Party Affiliate concerning STPC, the Company, the Placement Agents, any of their controlled affiliates, this Subscription Agreement or the transactions contemplated hereby.

13.   Disclosure.   STPC shall, by 9:00 a.m., New York City time, on the first (1st) business day immediately following the date of this Subscription Agreement, issue one or more press releases or file with the SEC a Current Report on Form 8-K (collectively, the “Disclosure Document”) disclosing all material terms of the transactions contemplated hereby and by the Other Subscription Agreements, the Transaction and any other material, nonpublic information that STPC has provided to the Investor at any time prior to the filing of the Disclosure Document. Upon the issuance of the Disclosure Document, to the actual knowledge of STPC, the Investor shall not be in possession of any material, non-public information received from STPC or any of its officers, directors, or employees or agents, and the Investor shall no longer be subject to any confidentiality or similar obligations under any current agreement, whether written or oral, with STPC or any of its affiliates, relating to the transactions contemplated by this Subscription Agreement. Notwithstanding anything in this Subscription Agreement to the contrary, STPC shall not publicly disclose the name of the Investor or any of its affiliates or advisers, or include the name of the Investor or any of its affiliates or advisers (i) in any press release or marketing materials without the prior consent of the Investor or (ii) in any filing with the SEC or any regulatory agency or trading market without the prior consent of the Investor, except in the case of clause (ii) as required by the federal securities law or pursuant to other routine proceedings of regulatory authorities or to the extent such disclosure is required by law, at the request of the staff of the SEC or regulatory agency or under the regulations of any national securities exchange on which STPC’s securities are listed for trading, in which case STPC shall provide Investor with prior written notice of such disclosure permitted under clause (ii).

14.   Separate Obligations.   The obligations of the Investor under this Subscription Agreement are several and not joint with the obligations of any Other Investor under the Other Subscription Agreements, and no Investor shall be responsible in any way for the performance of the obligations of any Other Investor under the Other Subscription Agreements.

Nothing contained herein or in any Other Subscription Agreement, and no action taken by Investor, shall be deemed to constitute Investor or any Other Investors under the Other Subscription Agreements as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that Investor or any Other Investors are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by the this Subscription Agreement and the Other Subscription Agreements. Investor acknowledges that no Other Investor has acted as agent for Investor in connection with making its investment hereunder and no Other Investor will be acting as agent of Investor in connection with monitoring its investment in the Shares or enforcing its rights under this Subscription Agreement. Investor shall be entitled to independently protect and enforce its rights, including without limitation the rights arising out of this Subscription Agreement, and it shall not be necessary for any Other Investor to be joined as an additional party in any proceeding for such purpose.

REGISTRATION RIGHTS.

2.1

Resale Shelf Registration Rights.

2.1.1

Registration Statement Covering Resale of Registrable Securities. Provided compliance by the Investors with Section 3.4, to the extent no such Registration Statement has been filed with the Commission prior to the date hereof, the Company shall prepare and file or cause to be prepared and filed with the Commission, as soon as practicable following the Closing Date, a Registration Statement on Form S-3 or its successor form, or, if the Company is ineligible to use Form S-3, a Registration Statement on Form S-1, for an offering to be made on a continuous basis pursuant to Rule 415 of the Securities Act registering the resale from time to time by Investors of all of the Registrable Securities then held by such Investors that are not covered by an effective resale registration statement (such Registration Statement, or any such Registration Statement filed with the Commission prior to the date hereof, the “Resale Shelf Registration Statement”). The Company shall use reasonable best efforts to cause the Resale Shelf Registration Statement to be declared effective as soon as possible after filing, and in no event later than thirty (30) days after the date of this Agreement, and once effective, to keep the Resale Shelf Registration Statement continuously effective under the Securities Act at all times until the expiration of the Effectiveness Period. In the event that the Company files a Form S-1 pursuant to this Section 2.1, the Company shall use its commercially reasonable efforts to convert the Form S-1 to a Form S-3 as soon as practicable after the Company is eligible to use Form S-3.

2.1.2

Notification and Distribution of Materials. The Company shall notify the Investors in writing of the effectiveness of the Resale Shelf Registration Statement and shall furnish to them, without charge, such number of copies of the Resale Shelf Registration Statement (including any amendments, supplements and exhibits), the prospectus contained therein (including each preliminary prospectus and all related amendments and supplements) and any documents incorporated by reference in the Resale Shelf Registration Statement or such other documents as the Investors may reasonably request in order to facilitate the sale of the Registrable Securities in the manner described in the Resale Shelf Registration Statement.

2.1.3

Amendments and Supplements. Subject to the provisions of Section 2.1.1 above, the Company shall promptly prepare and file with the Commission from time to time such amendments and supplements to the Resale Shelf Registration Statement and prospectus used in connection therewith as may be necessary to keep the Resale Shelf Registration Statement effective and to comply with the provisions of the Securities Act with respect to the disposition of all Registrable Securities during the Effectiveness Period.

Annex F-4

2.1.4

Registration of Additional Registrable Securities.

(i)

If a Resale Shelf Registration Statement is then effective, within ten (10) Business Days after written request therefore by a Permitted Transferee holding Registrable Securities not covered by an effective Resale Shelf Registration Statement, the Company shall file a post-effective amendment, prospectus supplement or current report on Form 8-K to add such Permitted Transferee as a selling stockholder in such Resale Shelf Registration Statement to the extent permitted under the rules and regulations promulgated by the Commission.

(ii)

The registration rights granted pursuant to the provisions of this Section 2.1.4 shall be in addition to the registration rights granted pursuant to the provisions of Section 2.2 and Section 2.3.

2.1.5

Reduction of Shelf Offering. Notwithstanding the registration obligations set forth in this Section 2.1, in the event the Commission informs the Company that all of the Registrable Securities cannot, as a result of the application of Rule 415, be registered for resale as a secondary offering on a single registration statement, the Company agrees to promptly (i) inform each of the holders thereof and use its commercially reasonable efforts to file amendments to the Resale Shelf Registration Statement as required by the Commission and/or (ii) withdraw the Resale Shelf Registration Statement and file a new registration statement (a “New Registration Statement”), in either case covering the maximum number of Registrable Securities permitted to be registered by the Commission, on Form S-1, Form S-3 or such other form available to register for resale the Registrable Securities as a secondary offering; provided, however, that prior to filing such amendment or New Registration Statement, the Company shall be obligated to use its commercially reasonable efforts to advocate with the Commission for the registration of all of the Registrable Securities in accordance with any publicly-available written or oral guidance, comments, requirements or requests of the Commission staff (the “SEC Guidance”), including, without limitation, the Manual of Publicly Available Telephone Interpretations D.29. Notwithstanding any other provision of this Agreement, if any SEC Guidance sets forth a limitation of the number of Registrable Securities permitted to be registered on a particular Registration Statement as a secondary offering (and notwithstanding that the Company used diligent efforts to advocate with the Commission for the registration of all or a greater number of Registrable Securities), unless otherwise directed in writing by a holder as to its Registrable Securities, the number of Registrable Securities to be registered on such Registration Statement will be reduced on a Pro Rata basis, subject to a determination by the Commission that certain Investors must be reduced first based on the number of Registrable Securities held by such Investors. In the event the Company amends the Resale Shelf Registration Statement or files a New Registration Statement, as the case may be, under clauses (i) or (ii) above, the Company will use its commercially reasonable efforts to file with the Commission, as promptly as allowed by Commission or SEC Guidance provided to the Company or to registrants of securities in general, one or more registration statements on Form S-1, Form S-3 or such other form available to register for resale those Registrable Securities that were not registered for resale on the Resale Shelf Registration Statement, as amended, or the New Registration Statement.

2.1.6

Notice of Certain Events. The Company shall promptly notify the Investors in writing of any request by the Commission for any amendment or supplement to, or additional information in connection with, the Resale Shelf Registration Statement required to be prepared and filed hereunder (or prospectus relating thereto). The Company shall promptly notify each Investor in writing of the filing of the Resale Shelf Registration Statement or any prospectus, amendment or supplement related thereto or any post-effective amendment to the Resale Shelf Registration Statement and the effectiveness of any post-effective amendment.

Annex F-5

2.1.7

Underwritten Takedown. If the Company shall receive a request from either (x) Existing Investors that hold at least a majority-in-interest of the outstanding Registrable Securities held by all Existing Investors, or (y) New Investors that hold at least a majority-in-interest of the outstanding Registrable Securities held by all New Investors, that the Company effect an Underwritten Takedown of all or any portion of the Registrable Securities of the requesting Investor(s), then the Company shall promptly give notice of such requested Underwritten Takedown at least seven (7) Business Days prior to the anticipated filing date of the prospectus or supplement relating to such Underwritten Takedown to the other Investors and thereupon shall use its reasonable best efforts to effect, as expeditiously as possible, the offering in such Underwritten Takedown of:

(i)

subject to the restrictions set forth in Section 2.2.4, all Registrable Securities for which the requesting holder has requested such offering under Section 2.1.7, and

(ii)

subject to the restrictions set forth in Section 2.2.4, all other Registrable Securities that any holders of Registrable Securities have requested the Company to offer by request received by the Company within two (2) Business Days after such holders receive the Company’s notice of the Underwritten Takedown, all to the extent necessary to permit the disposition (in accordance with the intended methods thereof as aforesaid) of the Registrable Securities so to be offered.

(a)

Promptly after the expiration of the two-Business Day-period referred to in Section 2.1.7(ii), the Company will notify all selling holders of the identities of the other selling holders and the number of shares of Registrable Securities requested to be included therein.

(b)

the Company shall only be required to effectuate three Underwritten Takedowns by the Investors within any 12-month period after giving effect to Section 2.2.1(i).

2.1.8

Block Trade. If the Company shall receive a request from the holders of Registrable Securities with an estimated market value of at least $10,000,000 that the Company effect the sale of all or any portion of the Registrable Securities in a Block Trade, then the Company shall, as expeditiously as possible, effect the offering in such Block Trade of the Registrable Securities for which such requesting holder has requested such offering under Section 2.1.7.

2.1.9

Selection of Underwriters. Selling holders holding a majority in interest of the Registrable Securities requested to be sold in an Underwritten Takedown shall have the right to select an Underwriter or Underwriters in connection with such Underwritten Takedown, which Underwriter or Underwriters shall be reasonably acceptable to the Company. In connection with an Underwritten Takedown, the Company shall enter into customary agreements (including an underwriting agreement in customary form) and take such other actions as are reasonably required in order to expedite or facilitate the disposition of the Registrable Securities in such Underwritten Takedown, including, if necessary, the engagement of a “qualified independent underwriter” in connection with the qualification of the underwriting arrangements with the Financial Industry Regulatory Authority, Inc.

2.1.10

Underwritten Takedowns effected pursuant to this Section 2.1 shall be counted as Demand Registrations effected pursuant to Section 2.2.

2.2

Demand Registration.

2.2.1

Request for Registration. At any time and from time to time after the expiration of any lock-up period to which a Demanding Holder’s shares are subject, if any, provided compliance by the Demanding Holders with Section 3.4, and provided further there is not an effective Resale Shelf Registration Statement available for the resale of the Registrable

Annex F-6

Securities pursuant to Section 2.1, (x) Existing Investors that hold at least a majority-in-interest of the outstanding Registrable Securities held by all Existing Investors or (y) New Investors that hold at least a majority-in-interest of the outstanding Registrable Securities held by all New Investors, in each case (the “Demanding Holders”), may make a written demand for Registration under the Securities Act of all or any portion of their Registrable Securities on Form S-1 or any similar long-form Registration or, if then available, on Form S-3. Each Registration requested pursuant to this Section 2.2.1 is referred to herein as a “Demand Registration”. Any demand for a Demand Registration shall specify the number of shares of Registrable Securities proposed to be sold and the intended method(s) of distribution thereof. The Company will notify all Investors that are holders of Registrable Securities of the demand, and each such holder of Registrable Securities who wishes to include all or a portion of such holder’s Registrable Securities in the Demand Registration (each such holder including shares of Registrable Securities in such Registration, a “Requesting Holder”) shall so notify the Company within fifteen (15) days after the receipt by the holder of the notice from the Company. Upon any such request, the Requesting Holder(s) shall be entitled to have their Registrable Securities included in the Demand Registration, subject to Section 2.2.4 and the provisos set forth in Section 3.1.1. The Company shall not be obligated to effect: (i) more than three Demand Registration during any 12-month period or (ii) any Demand Registration pursuant to this Section 2.2.1 at any time there is an effective Resale Shelf Registration Statement on file with the Commission pursuant to Section 2.1 that is available for resale of the Registrable Securities subject to Demand Registration.

2.2.2

Effective Registration. A Registration will not count as a Demand Registration until the Registration Statement filed with the Commission with respect to such Demand Registration has been declared effective and the Company has complied with all of its obligations under this Agreement with respect thereto; provided, however, that if, after such Registration Statement has been declared effective, the offering of Registrable Securities pursuant to a Demand Registration is interfered with by any stop order or injunction of the Commission or any other governmental agency or court, the Registration Statement with respect to such Demand Registration will be deemed not to have been declared effective, unless and until, (i) such stop order or injunction is removed, rescinded or otherwise terminated, and (ii) a majority-in-interest of the Demanding Holders thereafter elect to continue the offering; provided, further, that the Company shall not be obligated to file a second Registration Statement until a Registration Statement that has been filed is counted as a Demand Registration or is terminated.

2.2.3

Underwritten Demand Registration. If the Demanding Holders so elect and such holders so advise the Company as part of their written demand for a Demand Registration, the offering of such Registrable Securities pursuant to such Demand Registration shall be in the form of an Underwritten Demand Registration. In such event, the right of any such Demanding Holder or Requesting Holder (if any) to include its Registrable Securities in such registration shall be conditioned upon such holder’s participation in such Underwritten Demand Registration and the inclusion of such holder’s Registrable Securities in the Underwritten Demand Registration to the extent provided herein. All Demanding Holders or Requesting Holders (if any) proposing to distribute their Registrable Securities through an Underwritten Demand Registration under this Section 2.2.3 shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Underwritten Demand Registration by the majority-in-interest of the Demanding Holders initiating the Demand Registration. The parties agree that, in order to be effected, any Underwritten Demand Registration must be reasonably expected to result in aggregate gross proceeds to the selling stockholders of at least $10,000,000.

2.2.4

Reduction of Offering. If the managing Underwriter or Underwriters for an Underwritten Demand Registration advises the Company, the Demanding Holders and the Requesting Holders (if any) in writing that, in such Underwriter’s or Underwriters’ opinion, the dollar amount or number of shares of Registrable Securities which the Demanding Holders

Annex F-7

and the Requesting Holders (if any) desire to sell, taken together with all other Common Stock or other securities which the Company desires to sell and the Common Stock, if any, as to which registration has been requested pursuant to separate written contractual piggy-back registration rights held by other stockholders of the Company who desire to sell, exceeds the maximum dollar amount or maximum number of securities that can be sold in such 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 registration: (i) first, the Registrable Securities of the Demanding Holders and Requesting Holders 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 Demanding Holder or Requesting Holder has requested be included in such Demand Registration and the aggregate number of Registrable Securities that the Demanding Holders and Requesting Holders together have requested be included in such Demand Registration (such proportion is referred to herein as “Pro Rata”)) 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 the foregoing clause (i), the Common Stock or other securities that the Company desires to sell and that 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 the foregoing clauses (i) and (ii), the Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, as to which “piggy-back” registration has been requested by the holders thereof that can be sold without exceeding the Maximum Number of Securities.

2.2.5

Withdrawal. A majority-in-interest of the Demanding Holders may elect to withdraw from such Demand Registration by giving written notice to Company and the Underwriter or Underwriters of their request to withdraw prior to the effectiveness of the Registration Statement filed with the Commission with respect to such Demand Registration. If the majority-in-interest of the Demanding Holders withdraws from a proposed offering, then either the Demanding Holders shall reimburse Company for the costs associated with the withdrawn registration (in which case such registration shall not count as a Demand Registration provided for in Section 2.2.1) or the withdrawn registration shall count as a Demand Registration provided for in Section 2.2.1.

2.3

Piggy-Back Registration.

2.3.1

Piggy-Back Rights. If at any time after the expiration of any applicable lock-up period to which an Investor’s shares are subject, if any, provided compliance by the Investors with Section 3.4, the Company proposes to file a Registration Statement under the Securities Act with respect to an offering of equity securities, or securities or other obligations exercisable or exchangeable for, or convertible into, equity securities, by the Company for its own account or for stockholders of the Company for their account (or by the Company and by stockholders of the Company including, without limitation, pursuant to Section 2.2.1), other than a Registration Statement (i) filed in connection with any employee stock option or other benefit plan, (ii) for an exchange offer or offering of securities solely to the Company’s existing stockholders, (iii) for an offering of debt that is convertible into equity securities of the Company or (iv) for a dividend reinvestment plan, then the Company shall (a) give written notice of such proposed filing to the holders of Registrable Securities as soon as practicable but in no event less than ten (10) days before the anticipated filing date, which notice shall 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, of the offering, and (b) offer to the holders of Registrable Securities in such notice the opportunity to register the sale of such number of shares of Registrable Securities as such holders may request in writing within five (5) days following receipt of such notice (a “Piggy-Back

Annex F-8

Registration”). The Company shall cause such Registrable Securities to be included in such registration and shall use its best efforts to cause the managing Underwriter or Underwriters of a proposed underwritten offering to permit the Registrable Securities requested to be included in a Piggy-Back Registration on the same terms and conditions as any similar securities of the Company and to permit the sale or other disposition of such Registrable Securities in accordance with the intended method(s) of distribution thereof. All holders of Registrable Securities proposing to distribute their securities through a Piggy-Back Registration that involves an Underwriter or Underwriters shall enter into an underwriting agreement in customary form with the Underwriter or Underwriters selected for such Piggy-Back Registration.

2.3.2

Reduction of Offering. If the managing Underwriter or Underwriters for a Piggy-Back Registration that is to be an underwritten offering advises the Company and the holders of Registrable Securities in writing that the dollar amount or number of shares of Common Stock which the Company desires to sell, taken together with Common Stock, if any, as to which registration has been demanded pursuant to written contractual arrangements with persons other than the holders of Registrable Securities hereunder and the Registrable Securities as to which registration has been requested under this Section 2.3, exceeds the Maximum Number of Securities, then:

(a)

If the registration is undertaken for the Company’s account, the Company shall include in any such registration: (i) first, the Common Stock or other securities that the Company desires to sell 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 the foregoing clause (i), the Common Stock or other securities, if any, comprised of Registrable Securities, as to which registration has been requested pursuant to the terms hereof, that can be sold without exceeding the Maximum Number of Securities, Pro Rata; and (iii) third, to the extent that the Maximum Number of Securities has not been reached under the foregoing clauses (i) and (ii), the Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, as to which “piggy-back” registration has been requested by the holders thereof that can be sold without exceeding the Maximum Number of Securities; and

(b)

If the registration is a “demand” registration undertaken at the demand of persons other than either the holders of Registrable Securities, the Company shall include in any such registration: (i) first, the Common Stock or other securities for the account of the demanding persons and the Common Stock or other securities, if any, comprised of Registrable Securities, Pro Rata, as to which registration has been requested pursuant to the terms hereof, 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 the foregoing clause (i), the Common Stock or other securities that the Company desires to sell that 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 the foregoing clauses (i) and (ii), the Common Stock or other securities for the account of other persons that the Company is obligated to register pursuant to written contractual arrangements with such persons, that can be sold without exceeding the Maximum Number of Securities.

2.3.3

Withdrawal. Any holder of Registrable Securities may elect to withdraw such holder’s request for inclusion of Registrable Securities in any Piggy-Back Registration by giving written notice to the Company of such request to withdraw prior to the effectiveness of the Registration Statement, if such offering is pursuant to a Demand Registration, or prior to the public announcement of the offering, if such offering is pursuant to an Underwritten Takedown. The Company (whether on its own determination or as the result of a

Annex F-9

withdrawal by persons making a demand pursuant to written contractual obligations) may withdraw a Registration Statement filed with the Commission in connection with a Piggy-Back Registration at any time prior to the effectiveness of such Registration Statement. Notwithstanding any such withdrawal, the Company shall pay all expenses incurred by the holders of Registrable Securities in connection with such Piggy-Back Registration as provided in Section 3.3.

3.4

Information. The holders of Registrable Securities shall promptly provide such information as may reasonably be requested by the Company, or the managing Underwriter, if any, in connection with the preparation of any Registration Statement, including amendments and supplements thereto, in order to effect the registration of any Registrable Securities under the Securities Act and in connection with the Company’s obligation to comply with Federal and applicable state securities laws.

3.5

Other Obligations. At any time and from time to time after the expiration of any lock-up period to which such shares are subject, if any, in connection with a sale or transfer of Registrable Securities exempt from registration under the Securities Act or through any broker-dealer transactions described in the plan of distribution set forth within any prospectus and pursuant to the Registration Statement of which such prospectus forms a part, the Company shall, subject to the receipt of customary documentation required from the applicable holders in connection therewith, (i) promptly instruct its transfer agent to remove any restrictive legends applicable to the Registrable Securities being sold or transferred and (ii) cause its legal counsel to deliver the necessary legal opinions, if any, to the transfer agent in connection with the instruction under subclause (i).

3.6

Legend Removal Obligations. The Company shall, at the sole expense of the Company, remove any restrictive legend included on the certificates (or, in the case of book-entry shares, any other instrument or record) representing any Investor’s ownership of Registrable Securities, and the Company shall issue a certificate (or evidence of the issuance of such securities in book-entry form) without such restrictive legend or any other restrictive legend to such Investor, and shall cause the Company’s counsel to issue any legend removal opinion required by the transfer agent, if (i) such Registrable Securities are registered for resale under the Securities Act and the applicable Registration Statement has not been suspended pursuant to the Securities Act, the Exchange Act or the rules and regulations of the Commission promulgated thereunder, (ii) such Registrable Securities are sold or transferred pursuant to Rule 144, or (iii) such Registrable Securities are eligible for sale pursuant to Section 4(a)(1) of the Securities Act or Rule 144 without volume or manner-of-sale restrictions.

INDEMNIFICATION AND CONTRIBUTION.

4.1

Indemnification by the Company. The Company agrees to indemnify and hold harmless each Investor and each other holder of Registrable Securities, and each of their respective officers, employees, affiliates, directors, partners, members, attorneys and agents, and each person, if any, who controls an Investor and each other holder of Registrable Securities (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) (each, an “Investor Indemnified Party”), from and against any expenses, losses, judgments, claims, damages or liabilities, whether joint or several, arising out of or based upon any untrue statement (or allegedly untrue statement) of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to such Registration Statement, or arising out of or based upon any omission (or alleged omission) to state a material fact required to be stated therein or necessary to make the statements therein not misleading, or any violation by the Company of the Securities Act or any rule or regulation promulgated thereunder applicable to the Company and relating to action or inaction required of the Company in connection with any such registration; and the Company shall promptly reimburse the Investor Indemnified Party for any legal and any other expenses reasonably incurred by such Investor Indemnified Party in connection with investigating and defending any such expense, loss, judgment, claim, damage, liability or action; provided, however, that the Company will not be liable in any such case to the extent that any such expense, loss, claim, damage or liability arises out of or is based upon any untrue statement or allegedly untrue statement or omission or alleged omission made in such Registration Statement, preliminary prospectus, final prospectus, or summary prospectus, or any such amendment or supplement, in reliance upon and in conformity with information furnished to the Company, in writing, by such selling holder expressly for use therein, or is based on any selling holder’s violation of the federal securities laws (including Regulation M) or failure to sell the Registrable Securities in accordance with the plan of distribution contained in the prospectus.

4.2

Indemnification by Holders of Registrable Securities. Each selling holder of Registrable Securities will, in the event that any Registration is being effected under the Securities Act pursuant to this Agreement of any Registrable Securities held by such selling holder, indemnify and hold harmless the Company, each of its directors and officers, and each other selling holder and each other person, if any, who controls another selling holder within the meaning of the Securities Act, against any losses, claims, judgments, damages or liabilities, whether joint or several, insofar as such losses, claims, judgments, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or allegedly untrue statement of a material fact contained in any Registration Statement under which the sale of such Registrable Securities was registered under the Securities Act, any preliminary prospectus, final prospectus or summary prospectus contained in the Registration Statement, or any amendment or supplement to the Registration Statement, or arise out of or are based upon any omission or the alleged omission to state a material fact required to be stated therein or necessary to make the statement therein not misleading, if the statement or omission was made in reliance upon and in conformity with information furnished in writing to the Company by such selling holder expressly for use therein and shall reimburse the Company, its directors and officers, and each other selling holder or controlling person for any legal or other expenses reasonably incurred by any of them in connection with investigation or defending any such loss, claim, damage, liability or action. Each selling holder’s indemnification obligations hereunder shall be several and not joint and shall be limited to the amount of any net proceeds actually received by such selling holder.

4.3

Conduct of Indemnification Proceedings. Promptly after receipt by any person of any notice of any loss, claim, damage or liability or any action in respect of which indemnity may be sought pursuant to Sections 4.1 or 4.2, such person (the “Indemnified Party”) shall, if a claim in respect thereof is to be made against any other person for indemnification hereunder, notify such other person (the “Indemnifying Party”) in writing of the loss, claim, judgment, damage, liability or action; provided, however, that the failure by the Indemnified Party to notify the Indemnifying

Annex F-14

Party shall not relieve the Indemnifying Party from any liability which the Indemnifying Party may have to such Indemnified Party hereunder, except and solely to the extent the Indemnifying Party is actually prejudiced by such failure. If the Indemnified Party is seeking indemnification with respect to any claim or action brought against the Indemnified Party, then the Indemnifying Party shall be entitled to participate in such claim or action, and, to the extent that it wishes, jointly with all other Indemnifying Parties, to assume control of the defense thereof with counsel satisfactory to the Indemnified Party. After notice from the Indemnifying Party to the Indemnified Party of its election to assume control of the defense of such claim or action, the Indemnifying Party shall not be liable to the Indemnified Party for any legal or other expenses subsequently incurred by the Indemnified Party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that in any action in which both the Indemnified Party and the Indemnifying Party are named as defendants, the Indemnified Party shall have the right to employ separate counsel (but no more than one such separate counsel, which counsel is reasonably acceptable to the Indemnifying Party) to represent the Indemnified Party and its controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought by the Indemnified Party against the Indemnifying Party, with the fees and expenses of such counsel to be paid by such Indemnifying Party if, based upon the written opinion of counsel of such Indemnified Party, representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them. No Indemnifying Party shall, without the prior written consent of the Indemnified Party, consent to entry of judgment or effect any settlement of any claim or pending or threatened proceeding in respect of which the Indemnified Party is or could have been a party and indemnity could have been sought hereunder by such Indemnified Party, unless such judgment or settlement includes an unconditional release of such Indemnified Party from all liability arising out of such claim or proceeding.

4.4

Contribution.

4.4.1

If the indemnification provided for in the foregoing Sections 4.1, 4.2 and 4.3 is unavailable to any Indemnified Party in respect of any loss, claim, damage, liability or action referred to herein, then each such Indemnifying Party, in lieu of indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such loss, claim, damage, liability or action in such proportion as is appropriate to reflect the relative fault of the Indemnified Parties and the Indemnifying Parties in connection with the actions or omissions which resulted in such loss, claim, damage, liability or action, as well as any other relevant equitable considerations. The relative fault of any Indemnified Party and any Indemnifying Party shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by such Indemnified Party or such Indemnifying Party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

4.4.2

The parties hereto agree that it would not be just and equitable if contribution pursuant to this Section 4.4 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 Section 4.4.1.

4.4.3

The amount paid or payable by an Indemnified Party as a result of any loss, claim, damage, liability or action referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, any legal or other expenses incurred by such Indemnified Party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 4.4, no holder of Registrable Securities shall be required to contribute any amount in excess of the dollar amount of the net proceeds (after payment of any underwriting fees, discounts, commissions or taxes) actually received by such holder from the sale of Registrable Securities which gave rise to such contribution obligation. No person guilty of fraudulent misrepresentation

Annex F-15

(within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

5.

RULE 144. The Company covenants that it shall file any reports required to be filed by it under the Securities Act and the Exchange Act and shall take such further action as the holders of Registrable Securities may reasonably request, all to the extent required from time to time to enable such holders to sell Registrable Securities without registration under the Securities Act within the limitation of the exemptions provided by Rule 144, as such Rules may be amended from time to time, or any similar rule or regulation hereafter adopted by the Commission.

6.

6.1.4

If a vacancy occurs because of the death, disability, disqualification, resignation, or removal of a Sponsor Director or for any other reason, the Sponsor shall be entitled to designate such person’s successor (subject, in the case of a Joint Nominee, to the consent of the Company), and the Company will, as promptly as practicable following such designation, use its best efforts to take all necessary and desirable actions, to the fullest extent permitted by law, within its control such that such vacancy shall be filled with such successor Nominee.

For so long as a Sponsor Director serves as a director of the Company, the Company shall not amend, alter or repeal any right to indemnification or exculpation covering or benefiting any director nominated pursuant to this Agreement as and to the extent consistent with applicable law, whether such right is contained in the Certificate of Incorporation or Bylaws, each as amended, or another document (except to the extent such amendment or alteration permits the Company to provide broader indemnification or exculpation rights on a retroactive basis than permitted prior thereto).

6.1.9

The Joint Nominee shall qualify as “independent” pursuant to listing standards of the New York Stock Exchange (or such other national securities exchange upon which the Company’s securities are then listed).

6.1.10

Any 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 Nominee provided (a) it does so in good faith, and (b) such objection is based upon any of the following: (i) such 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 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 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 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 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, or (v) such 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. In the event the Company Board reasonably finds the Nominee to be unsuitable based upon one or more of the foregoing clauses (i) through (v) and reasonably objects to the Nominee, Sponsor shall be entitled to propose a different nominee (subject, in the case of a Joint Nominee, to the consent of the Company) to the Company Board within 30 calendar days of the Company’s notice to Sponsor of its objection to the Nominee and such replacement Nominee shall be subject to the review process outlined above.

6.1.11

The Company shall take all necessary action to cause a Nominee chosen by the Sponsor, at the request of such Nominee to be elected to the board of directors (or similar governing body) of each material operating subsidiary of the Company.

Other Registration Rights and Arrangements. Except for such sections that expressly survive termination, the parties hereby terminate the Prior Agreement, which shall be of no further force and effect and is hereby superseded and replaced in its entirety by this Agreement. The Company shall not hereafter enter into any agreement with respect to its securities which is inconsistent with or violates the rights granted to the holders of Registrable Securities in this Agreement and in the event of any conflict between any such agreement or agreements and this Agreement, the terms of this Agreement shall prevail.

7.2

Assignment; No Third-Party Beneficiaries. This Agreement and the rights, duties and obligations of the Company hereunder may not be assigned or delegated by the Company in whole or in part. This Agreement and the rights, duties and obligations of the holders of Registrable Securities hereunder may be freely assigned or delegated by such holder of Registrable Securities in conjunction with and to the extent of any permitted transfer of Registrable Securities by any such holder. This Agreement and the provisions hereof shall be binding upon and shall inure to the benefit to a Permitted Transferee of each of the parties hereto and their respective successors and assigns and the holders of Registrable Securities and their respective successors and permitted assigns.

No course of dealing between any Investor or the Company and any other party hereto or any failure or delay on the part of an Investor or the Company in exercising any rights or remedies under this Agreement shall operate as a waiver of any rights or remedies of any Investor or the Company. No single or partial exercise of any rights or remedies under this Agreement by a party shall operate as a waiver or preclude the exercise of any other rights or remedies hereunder or thereunder by such party.

7.4

Term. This Agreement shall terminate on the date as of which there shall be no Registrable Securities outstanding.

This SPONSOR SUPPORT AGREEMENT (this “Agreement”), dated as of May 8, 2021, is made by and among Star Peak Corp II, a Delaware corporation (“STPC”), Benson Hill, Inc., a Delaware corporation (the “Company”), Star Peak Sponsor II LLC, a Delaware limited liability company (“Sponsor”), and the undersigned holders of STPC Class B Shares (the holders thereof, including Sponsor, collectively, the “Class B Holders”). STPC, the Company and the Class B Holders shall be referred to herein from time to time collectively as the “Parties”. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Merger Agreement (as defined below).

WHEREAS, STPC, the Company and STPC II Merger Sub Corp., a Delaware corporation, entered into that certain Merger Agreement, dated as of the date hereof (as may be amended, restated or otherwise modified from time to time in accordance with its terms, the “Merger Agreement”);

WHEREAS, the Class B Holders are the record and beneficial owners of all of the issued and outstanding STPC Class B Shares;

WHEREAS, pursuant to the Charter (as defined below), all of the STPC Class B Shares will be converted into STPC Common Shares at the time of consummation of the Merger (the “Conversion”); and

WHEREAS, the Merger Agreement contemplates that the Parties will enter into this Agreement concurrently with the execution and delivery of the Merger Agreement by the parties thereto, pursuant to which, among other things, (a) each Class B Holder will vote (or execute and return an action by written consent), or cause to be voted, all Subject STPC Equity Securities (as defined below) in favor of approval of the Merger Agreement, the Merger, the issuance of the STPC Common Shares as consideration in the Merger pursuant to Section 2.2(a) of the Merger Agreement and the other transactions contemplated by the Merger Agreement (the “Proposals”), (b) Sponsor will agree that following the Conversion, a certain amount of its STPC Common Shares will be subject to substantially the same terms and restrictions as apply to Earn Out Shares and (c) each Class B Holder will agree to waive any adjustment to the conversion ratio set forth in the Governing Documents of STPC or any other anti-dilution or similar protection with respect to all of the STPC Class B Shares related to the transactions contemplated by the Merger Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows:

1.   Agreement to Vote. Each Class B Holder hereby irrevocably and unconditionally agrees (a) to vote at any meeting of the shareholders of STPC, and in any action by written resolution of the shareholders of STPC, all of such Class B Holder’s STPC Class B Shares (together with any other equity securities of STPC that such Class B Holder holds of record or beneficially, as of the date of this Agreement, or acquires record or beneficial ownership after the date hereof, collectively, the “Subject STPC Equity Securities”) (i) in favor of the Proposals and (ii) against, and withhold consent with respect to, any Alternative Business Combination Proposal (as defined below) and any other matter, action or proposal that would reasonably be expected to or result in (x) a breach of any of the STPC’s or Merger Sub’s covenants, agreements or obligations under the Merger Agreement or (y) any of the conditions to the Closing set forth in Sections 6.1 or 6.3 of the Merger Agreement not being satisfied, (b) if a meeting is held in respect of the matters set forth in clause (a), to appear at the meeting, in person or by proxy, or otherwise cause all of such Class B Holder’s Subject STPC Equity Securities to be counted as present thereat for purposes of establishing a quorum and (c) not to redeem, elect to redeem or tender or submit any of its Subject STPC Equity Securities for redemption in connection with such stockholder approval, the Merger or any other transactions contemplated by the Merger Agreement. Prior to any valid termination of the Merger Agreement, each Class B Holder shall take, or cause to be taken, all actions and to do, or cause to be done, all things reasonably necessary under applicable Laws to consummate the Merger and the other transactions contemplated by the Merger Agreement and on the terms and subject to the conditions set forth therein. The obligations of each Class B Holder

Annex G-1

specified in this Section 1 shall apply whether or not the Merger, any of the transactions contemplated by the Merger Agreement or any action described above is recommend by STPC’s board of directors.

2.   Waiver of Anti-dilution Protection.

(a)   The Class B Holders hereby irrevocably and unconditionally relinquish and waive (the “Waiver”) the right of holders of STPC Class B Shares under Section 4.3(b)(ii) of the STPC’s Amended and Restated Certificate of Incorporation (the “Charter”) to receive STPC Class A Shares in excess of the number issuable at the Initial Conversion Ratio (as defined in the Charter) (the “Excess Shares”) upon conversion of the STPC Class B Shares in connection with the Merger as a result of any adjustment caused by issuances made in respect the PIPE Financing.

(b)   Each Class B Holder acknowledges and agrees that if such Class B Holder receives any Excess Shares as a result of any adjustment caused by the issuance in respect of the PIPE Financing, such issuance of Excess Shares shall be void, ab initio and such Excess Shares shall automatically be deemed to be surrendered for no consideration to STPC for cancellation. Each Class B Holder agrees to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable to consummate and make effective the immediately preceding sentence, including promptly surrendering such shares to STPC for cancellation for no consideration (and any evidence of issuance thereof, whether book-entry or certificates).

3.   Sponsor Earn Out.

(i)   998,250 of the Sponsor Earn Out Shares will vest upon the occurrence of Triggering Event I (the “$14 Sponsor Earn Out Shares”); and

(ii)   998,250 of the Sponsor Earn Out Shares will vest upon the occurrence of Triggering Event II (the “$16 Sponsor Earn Out Shares”).

For illustrative purposes, if, prior to the expiration of the Earn Out Period:

(i)   the Closing Price of the STPC Common Shares is greater than or equal to $14.00 over any twenty (20) Trading Days within any thirty- (30-) consecutive Trading Day period, all of the $14 Sponsor Earn Out Shares shall vest upon such Triggering Event as determined in accordance with Section 3(d); and

(ii)   the Closing Price of the STPC Common Shares is greater than or equal to $16.00 over any twenty (20) Trading Days within any thirty- (30-) consecutive Trading Day period, all of the $16 Sponsor Earn Out Shares shall vest upon such Triggering Event as determined in accordance with Section 3(d) and, if not already vested, all of the $14 Sponsor Earn Out Shares shall also vest.

(b)   Subject to the limitations contemplated herein, Sponsor shall have all of the rights of a stockholder with respect to the Sponsor Earn Out Shares, including the right to receive dividends and to vote such shares; provided that the unvested Sponsor Earn Out Shares shall not entitle Sponsor to consideration in connection with any sale or other transaction (other than, for the avoidance of doubt, as part of a Company Sale) and may not be offered, sold, transferred, redeemed, assigned, pledged, hypothecated, encumbered or otherwise disposed of (whether by operation of law or otherwise) by Sponsor or be subject to execution, attachment or similar process without the consent of STPC, and shall bear a customary legend with respect to such transfer restrictions. Any attempt to sell, transfer, assign, pledge, hypothecate, encumber or otherwise dispose of such unvested Sponsor Earn Out Shares shall be null and void. Notwithstanding the foregoing, the Sponsor Earn Out Shares may be transferred in accordance with Section 5(c) of the Sponsor Letter Agreement (as defined below) as such provision applies to Founder Shares (as

Annex G-2

defined in the Sponsor Letter Agreement), provided that the applicable permitted transferee and the transferred Sponsor Earn Out Shares shall otherwise be subject to the terms and conditions set forth in this Section 3.

(c)   If the applicable Triggering Event has not occurred prior to the expiration of the Earn Out Period, then all Sponsor Earn Out Shares which would vest in connection with such Triggering Event shall be automatically forfeited and deemed transferred to STPC and shall be cancelled by STPC and cease to exist. For the avoidance of doubt, prior to such forfeiture, all Sponsor Earn Out Shares shall be entitled to any dividends or distributions made to the holders of STPC Common Shares and shall be entitled to the voting rights generally granted to holders of STPC Common Shares.

(d)   In the event of occurrence of any Triggering Event set forth in Section 3(a), as soon as practicable (but in any event within three (3) Business Days), STPC will deliver to Sponsor a written statement (each, a “Sponsor Stock Price Earn Out Statement”) that sets forth (i) the Closing Price over the applicable thirty- (30-) consecutive Trading Day period and (ii) the calculation of the Sponsor Earn Out Shares in connection therewith, including any adjustments made pursuant to a stock split, stock dividend, reorganizations, recapitalizations and the like. Sponsor may deliver written notice to STPC on or prior to the fifteenth (15th) day after receipt of a Sponsor Stock Price Earn Out Statement, either (x) accepting the Sponsor Stock Price Earn Out Statement or (y) specifying in reasonable detail any items that it wishes to dispute and the basis therefor. If Sponsor fails to deliver such written notice in such fifteen (15) day period, then Sponsor will be deemed to have waived its right to contest such Sponsor Stock Price Earn Out Statement and the calculations set forth therein, and such Sponsor Stock Price Earn Out Statement and calculations set forth therein shall be deemed final and binding. If Sponsor provides STPC with written notice of any objections to the Sponsor Stock Price Earn Out Statement in such fifteen (15) day period, then Sponsor and STPC will, for a period of fifteen (15) days following the date of delivery of such notice, attempt to resolve their differences and any written resolution by them as to any disputed amount will be final and binding for all purposes under this Agreement. If at the conclusion of such fifteen (15) day period Sponsor and STPC have not reached an agreement on any objections with respect to the Sponsor Stock Price Earn Out Statement, then upon the written request of either STPC or Sponsor, the dispute shall be referred to an independent accountant of national standing as shall be mutually agreed upon in good faith by STPC and Sponsor for final resolution of the dispute as promptly as practicable. Upon final determination of the items set forth in the Sponsor Stock Price Earn Out Statement as contemplated by this Section 3(d), the applicable Sponsor Earn Out Shares shall be deemed to have vested upon such applicable Triggering Event in accordance with such Sponsor Stock Price Earn Out Statement. In the event STPC fails to deliver the Sponsor Stock Price Earn Out Statement within the three (3) Business Day period described above, Sponsor shall be entitled to deliver the Sponsor Stock Price Earn Out Statement, and any disputes and the resolution process set forth in this Section 3(d) shall, in such circumstances, apply mutatis mutandis. Notwithstanding anything to the contrary, to the extent the applicable Sponsor Earn Out Shares have not already vested, (i) the $14 Sponsor Earn Out Shares shall vest immediately upon vesting of the $14 Earn Out Shares and (ii) the $16 Sponsor Earn Out Shares shall vest immediately upon vesting of the $16 Earn Out Shares.

(e)   In the event that there is a Company Sale after the Closing and prior to the expiration of the Earn Out Period, if the sale price per share or implied sale price per share based on the company sale price at the closing of the Company Sale is at least $14 (with respect to Triggering Event I and the $14 Sponsor Earn Out Shares) or $16 (with respect to Triggering Event II and the $16 Sponsor Earn Out Shares), in each case, taking into account the number of Sponsor Earn Out Shares that would be vested as if the STPC Common Shares had been trading at a Closing Price equal to such sale price per share or implied sale price per share in connection with such Company Sale, as applicable, for the requisite period set forth in Section 3(a) necessary to satisfy the applicable Triggering Event, then (i) immediately prior to the consummation of the Company Sale, Triggering Event I or Triggering Event II (as applicable) that has not previously occurred shall be and the related vesting conditions in Section 3(d) also shall be deemed to have occurred,

Annex G-3

(ii) such Sponsor Earn Out Shares shall immediately vest and (iii) Sponsor (or any other holders of such Sponsor Earn Out Shares) shall be eligible to participate in such Company Sale.

(f)   The Parties intend that the Conversion will be treated as a tax-free recapitalization under Section 368(a)(1)(E) of the Internal Revenue Code of 1986, as amended (the “Code”), and Sponsor intends to make a protective election under Section 83(b) of the Code with respect to the receipt of the portion of the STPC Common Stock subject to vesting under this Section 3.

4.   Working Capital. Prior to the Closing, Sponsor hereby agrees to continue to fund (whether by Working Capital Loans or otherwise) the working capital expenses of STPC arising in the ordinary course of its business.

ANNEX H​

FORM OF LOCK-UP AGREEMENT

THIS LOCK-UP AGREEMENT (this “Agreement”) is made and entered into as of [•], 2021 by and among (i) Star Peak Corp II, a Delaware corporation (together with its successors, “STPC”), (ii) Benson Hill, Inc., a Delaware corporation (the “Company”), and (iii) the undersigned (“Holder”). Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the Merger Agreement (as defined below).

WHEREAS, STPC, STPC II Merger Sub Corp., a Delaware corporation and a direct wholly-owned subsidiary of STPC (“Merger Sub”), and the Company [entered into that // are substantially contemporaneously entering into that] certain Agreement and Plan of Merger, [dated as of [•], 2021 // on or about the date hereof] (as amended from time to time in accordance with the terms thereof, the “Merger Agreement”), pursuant to which, among other matters, upon the consummation of the transactions contemplated thereby (the “Closing”), Merger Sub will merge with and into the Company, with the Company continuing as the surviving entity and a wholly-owned subsidiary of STPC (the “Merger”), and as a result of which all of the issued and outstanding capital stock of the Company immediately prior to the Closing shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, in exchange for the right to receive newly issued STPC Common Shares and [STPC Options], all upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with the applicable provisions of the DGCL;

WHEREAS, as of the date hereof, Holder is a holder of equity securities of the Company in such amounts and classes or series as set forth underneath Holder’s name on the signature page hereto; and

WHEREAS, pursuant to the Merger Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties desire to enter into this Agreement, pursuant to which the STPC Common Shares (including any Earn Out Shares), STPC Options and STPC Converted Warrants, as applicable, to be received by Holder as consideration in the Merger, including any STPC Common Shares (including any Earn Out Shares) underlying the STPC Options or STPC Converted Warrants (all such securities, together with any securities paid as dividends or distributions with respect to such securities or into which such securities are exchanged or converted, the “Restricted Securities”) shall become subject to limitations on disposition as set forth herein.

NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to be legally bound hereby, the parties hereby agree as follows:

1.   Lock-up Provisions.

(a)   Holder hereby agrees not to (1) Transfer any Restricted Securities from and after the Closing and until the earlier of (x) the date that is six (6) months following the Closing and (y) the date after the Closing on which STPC completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of STPC’s stockholders having the right to exchange their equity holdings in STPC for cash, securities or other property (clause (y), a “Liquidity Event”, and such period, the “Lock-up Period”), and (2) from and after the execution of the Merger Agreement and until the end of the Lock-Up Period, directly or indirectly, engage in any short sales or other hedging or derivative transactions in respect of STPC Common Shares or STPC Warrants; provided that the foregoing restrictions shall not apply to the Transfer of any or all of the Restricted Securities owned by Holder made in respect of a Permitted Transfer (as defined below); provided, further, that in any of case of a Permitted Transfer, it shall be a condition to such Transfer that the transferee executes and delivers to STPC and the Company an agreement, in substantially the same form of this Agreement, stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement applicable to Holder, and there shall be no further Transfer of such Restricted Securities except in accordance with this Agreement. As used herein, “Transfer” shall mean (i) the sale of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or

Annex H-1

agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position or liquidation with respect to or decrease of a call equivalent position within the meaning of Section 16 of the Exchange Act, and the rules and regulations of the SEC promulgated thereunder with respect to, any security, (ii) entry into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any security, whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) public announcement of any intention to effect any transaction specified in clause (i) or (ii). As used in this Agreement, the term “Permitted Transfer” shall mean a Transfer made: (A) in the case of Holder being an individual, by gift to a member of one of the individual’s immediate family, an estate planning vehicle or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (B) in the case of Holder being an individual, by virtue of laws of descent and distribution upon death of Holder; (C) in the case of Holder being an individual, pursuant to a qualified domestic relations order; (D) by pro rata distributions from Holder to its members, partners, or shareholders pursuant to the Holder’s organizational documents; (E) by virtue of applicable law or the Holder’s organizational documents upon liquidation or dissolution of Holder; (F) to STPC for no value for cancellation in connection with the consummation of a Liquidity Event or the cashless exercise of options or warrants of STPC (provided that, for the avoidance of doubt, any securities received in such cashless exercise shall be deemed to be Restricted Securities hereunder); (G) in the event of STPC’s liquidation prior to the completion of a Liquidity Event; (H) in the event of completion of a liquidation, merger, capital stock exchange, reorganization or other similar transaction which results in all of the STPC’s holders of STPC Common Shares having the right to exchange their STPC Common Shares for cash, securities or other property subsequent to the completion of a Liquidity Event; or (I) to any employees, officers, directors or members of the Holder or any affiliates of the Holder.

(b)   If any Transfer is made or attempted contrary to the provisions of this Agreement, such purported Transfer shall be null and void ab initio, and STPC shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equityholders for any purpose. In order to enforce this Section 1, STPC may impose stop-transfer instructions with respect to the Restricted Securities of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-up Period.

(c)   During the Lock-up Period, each certificate evidencing any Restricted Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable legends:

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [•], 2021, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), THE ISSUER’S SECURITY HOLDER NAMED THEREIN AND CERTAIN OTHER PARTIES NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

(d)   For the avoidance of any doubt, (i) Holder shall retain all of its rights as a stockholder of STPC during the Lock-up Period, including the right to vote, and to receive any dividends and distributions in respect of, any Restricted Securities, and (ii) the restrictions contained in clause (1) of Section 1(a) shall not apply to any STPC Common Shares or other securities of STPC acquired by Holder in open market transactions or in any public or private capital raising transactions of STPC or otherwise to any STPC Common Shares (or other securities of STPC) other than the Restricted Securities.

(e)   In connection with the written request of Holder, following the expiration of the Lock-up Period or in connection with a release of restrictions on Transfer pursuant to Section 1(a), the Company shall remove any restrictive legend included on the certificates (or, in the case of book-entry shares, any other instrument or record) representing Holder and/or its Affiliates or permitted transferee’s ownership of Common Shares, and the Company shall issue a certificate (or

Annex H-2

evidence of the issuance of securities in book-entry form) without such restrictive legend or any other restrictive legend to the holder of the applicable Common Shares upon which it is stamped, if (i) such Common Shares are registered for resale under the Securities Act and the Registration Statement for such Common Shares has not been suspended pursuant to the Securities Act, the Exchange Act or the rules and regulations of the Commission promulgated thereunder, (ii) such Common Shares are sold or transferred pursuant to Rule 144, or (iii) such Common Shares are eligible for sale pursuant to Section 4(a)(1) of the Securities Act or Rule 144 without volume or manner-of-sale restrictions. Following the earlier of (A) the effective date of a Registration Statement registering such Common Shares or (B) Rule 144 becoming available for the resale of such Common Shares without volume or manner-of-sale restrictions, the Company, upon the written request of Holder or its permitted transferee and the provision by such person of an opinion of reputable counsel reasonably satisfactory to the Company and the Company’s transfer agent, shall instruct the Company’s transfer agent to remove the legend from such Common Shares (in whatever form) and shall cause Company counsel to issue any legend removal opinion required by the transfer agent. Any fees (with respect to the transfer agent, Company counsel, or otherwise) associated with the removal of such legend (except for the provision of the legal opinion by Holder or its permitted transferee to the transfer agent referred to above) shall be borne by the Company. If a legend is no longer required pursuant to the foregoing, the Company will no later than two (2) Business Days following the delivery by Holder or its permitted transferee to the Company or the transfer agent (with notice to the Company) of a legended certificate (if applicable) representing such Common Shares and, to the extent required, a seller representation letter representing that such Common Shares may be sold pursuant to Rule 144, and a legal opinion of reputable counsel reasonably satisfactory to the Company and the transfer agent, deliver or cause to be delivered to the holder of such Common Shares a certificate representing such Common Shares (or evidence of the issuance of such Common Shares in book-entry form) that is free from all restrictive legends.

2.   Miscellaneous.

(a)   Termination of Merger Agreement. Notwithstanding anything to the contrary contained herein, in the event that the Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights and obligations of the parties hereunder shall automatically terminate and be of no further force or effect; provided that, such termination shall not affect any Liability on the part of any party for a willful breach of any covenant or agreement set forth in this Agreement prior to such termination.

(b)   Binding Effect; Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. This Agreement and all obligations of Holder are personal to Holder and may not be transferred or delegated by Holder at any time without the prior written consent of STPC, the Company and Sponsor (as defined below). Each of STPC and the Company may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder.

(c)   Third Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person or entity that is not a party hereto or thereto or a successor or permitted assign of such a party; provided, that Star Peak Sponsor II LLC, a Delaware limited liability company (“Sponsor”), shall be an express third party beneficiary of this Agreement and shall have the right to enforce the terms of this Agreement directly against Holder as if Sponsor were an original party hereto.

(d)   Governing Law; Jurisdiction; Waiver of Jury Trial: Remedies. This Agreement and all related Proceedings shall be governed by and construed in accordance with the internal Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction other than the State of Delaware. THE PARTIES HERETO EACH

Annex H-3

HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. THE PARTIES HERETO EACH HEREBY AGREE AND CONSENT THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES HERETO MAY FILE AN ORIGINAL COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. The parties hereto expressly incorporate by reference Section 8.16 (Jurisdiction) of the Merger Agreement and, subject to Section 2(i) hereof, Section 8.17 (Remedies) of the Merger Agreement to apply to this Agreement mutatis mutandis, with references to the Merger Agreement therein deemed to reference this Agreement and references to the “Parties” thereunder deemed to reference the parties hereto.

(e)   Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any Party. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

(f)   Construction; Interpretation. The headings set forth in this Agreement are inserted for convenience only and shall not affect in any way the meaning or interpretation of this Agreement. No party hereto, nor its respective counsel, shall be deemed the drafter of this Agreement for purposes of construing the provisions hereof, and all provisions of this Agreement shall be construed according to their fair meaning and not strictly for or against any such party. Unless otherwise indicated to the contrary herein by the context or use thereof: (a) the words, “herein,” “hereto,” “hereof” and words of similar import refer to this Agreement as a whole, and not to any particular section, subsection, paragraph, subparagraph or clause set forth in this Agreement; (b) masculine gender shall also include the feminine and neutral genders, and vice versa; (c) words importing the singular shall also include the plural, and vice versa; (d) the words “include,” “includes” or “including” shall be deemed to be followed by the words “without limitation”; (e) references to “$” or “dollar” or “US$” shall be references to United States dollars; (f) the word “or” is disjunctive but not necessarily exclusive; (g) the words “writing,” “written” and comparable terms refer to printing, typing and other means of reproducing words (including electronic media) in a visible form; (h) the word “extent” in the phrase “to the extent” means the degree to which a subject or other thing extends, and such phrase shall not mean simply “if”; (i) all references to Articles or Sections are to Articles or Sections of this Agreement; and (j) all references to any Law will be to such Law as amended, supplemented or otherwise modified from time to time.

(g)   Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and shall be given (and shall be deemed to have been duly given) when delivered in person, when delivered by e-mail (having obtained electronic delivery confirmation thereof), or when sent by registered or certified mail (postage prepaid, return receipt requested) (upon receipt thereof) to the other parties hereto as follows:

The observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of the party against whom enforcement of such waiver is sought. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision. STPC and the Company hereby represent, warrant, covenant and agree that (i) if any Lock-Up Agreement signed by the Sponsor or a stockholder of the Company in connection with the transactions contemplated hereby is amended, modified or waived in a manner favorable to the Sponsor or such stockholder and that would be favorable to Holder, this Agreement shall be contemporaneously amended in the same manner and STPC shall provide prompt notice thereof to Holder, and (ii) if the Sponsor or any such stockholder is released from any or all of the lock-up restrictions under its Lock-Up Agreement, Holder will be similarly and contemporaneously released from the lock-up restrictions hereunder (which, for the avoidance, of doubt will include a release of the same percentage of Holder’s Restricted Securities) and STPC shall provide prompt notice thereof to Holder.

Accordingly, each of STPC and the Company (or Sponsor on their behalf) shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by Holder and to enforce specifically the terms and provisions hereof, without the requirement to post

Evidence of an Award may be in written or electronic form, may be limited to notation on the books and records of the Company and, with the approval of the Administrator, need not be signed by a representative of the Company or a Participant.

(ii)   there is consummated a merger, consolidation or similar transaction involving (directly or indirectly) the Company and, immediately after the consummation of such merger, consolidation or similar transaction, the stockholders of the Company immediately prior thereto do not Own, directly or indirectly, either (A) outstanding voting securities representing fifty percent (50%) or more of the combined outstanding voting power of the surviving Entity in such merger, consolidation or similar transaction or (B) fifty percent (50%) or more of the combined outstanding voting power of the ultimate parent of the surviving Entity in such merger, consolidation or similar transaction, in each case in substantially the same proportions as their Ownership of the outstanding voting securities of the Company immediately prior to such transaction;

Notwithstanding anything to the contrary, a “Change in Control” shall not include a sale of assets, merger or other transaction effected exclusively for the purpose of changing the domicile of the Company or be deemed to have occurred by virtue of the consummation of any transaction or series of integrated transactions immediately following which the holders of Common Stock immediately prior to such transaction or series of transactions continue to have substantially the same proportionate ownership in an entity which owns all or substantially all of the assets of the Company immediately following such transaction or series of transactions.

If required for compliance with Code Section 409A, in no event shall a Change in Control be deemed to have occurred if such transaction is not also a “change in the ownership or effective control of” the Company or “a change in the ownership of a substantial portion of the assets of” the Company as determined under U.S. Treasury Regulation §1.409A-3(i)(5) (without regard to any alternative definition thereunder).

Notwithstanding the foregoing, in the case of an Incentive Stock Option or any determination relating to an Incentive Stock Option, “Subsidiary” means a corporation that is a subsidiary of the Company within the meaning of Code Section 424(f).

(xx)   “Substitute Award” shall mean an Award granted under the Plan upon the assumption of, or in substitution for, outstanding equity awards granted by a company or other entity in connection with a corporate transaction, such as a merger, combination, consolidation, or acquisition of property or stock; provided, however, that in no event shall the term “Substitute Award” be construed to refer to an award made in connection with the cancellation and repricing of an Option or Stock Appreciation Right. For the avoidance of doubt, the assumed stock options referenced at Section 4(a)(ii) of the Plan shall not constitute Substitute Awards and shall be treated as Awards granted under the Plan, including for purposes of the Plan's share reserve and the share recycling provisions set forth in Section 4(c) of the Plan.

Section 3.   Administration.

(a)   The Plan shall be administered by the Administrator. To the extent required to comply with the provisions of Rule 16b-3 promulgated under the Exchange Act (“Rule 16b-3”) (if the Board is not acting as the Committee under the Plan), it is intended that each member of the Committee shall, at the time he or she takes any action with respect to an Award under the Plan that is intended to qualify for the exemptions provided by Rule 16b-3, be an Eligible Director. However, the fact that a Committee member shall fail to qualify as an Eligible Director shall not invalidate any Award granted by the Committee that is otherwise validly granted under the Plan.

(b)   Pursuant to the terms of the Plan, the Administrator, subject, in the case of any Committee, to any restrictions on the authority delegated to it by the Board, shall have the power and authority, without limitation:

(i)   to select those Eligible Recipients who shall be Participants;

Annex I-7

(ii)   to determine whether and to what extent Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units, Other Share-Based Awards, Other Cash-Based Awards or a combination of any of the foregoing, are to be granted hereunder to Participants;

(iii)   to determine the number of shares of Common Stock to be made subject to each Award;

(iv)   to determine the terms and conditions, not inconsistent with the terms of the Plan, of each Award granted hereunder, including, but not limited to, (A) the restrictions applicable to Awards and the conditions under which restrictions applicable to such Awards shall lapse, (B) the Performance Goals and performance periods applicable to Awards, if any, (C) the Exercise Price of each Award, (D) the vesting schedule applicable to each Award, (E) any confidentiality or restrictive covenant provisions applicable to the Award, and (F) subject to the requirements of Code Section 409A (to the extent applicable), any amendments to the terms and conditions of outstanding Awards, including, but not limited to, extending the exercise period of such Awards and accelerating the vesting schedule of such Awards;

(v)   to determine the terms and conditions, not inconsistent with the terms of the Plan, which shall govern all Award Agreements evidencing Options, Stock Appreciation Rights, Restricted Shares, Restricted Stock Units or Other Share-Based Awards, Other Cash-Based Awards or any combination of the foregoing granted hereunder;

(vi)   to determine Fair Market Value;

(vii)   to determine the duration and purpose of leaves of absence which may be granted to a Participant without constituting termination of the Participant’s employment for purposes of Awards granted under the Plan;

(viii)   to adopt, alter and repeal such administrative rules, guidelines and practices governing the Plan as it shall from time to time deem advisable;

(ix)   to reconcile any inconsistency in, correct any defect in and/or supply any omission in the Plan, any Award Agreement or other instrument or agreement relating to the Plan or an Award granted under the Plan; and

(x)   to construe and interpret the terms and provisions of the Plan and any Award issued under the Plan (and any Award Agreement relating thereto), and to otherwise supervise the administration of the Plan and to exercise all powers and authorities either specifically granted under the Plan or necessary and advisable in the administration of the Plan.

(c)   Except to the extent prohibited by applicable law or the applicable rules and regulations of any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or traded, the Administrator may allocate all or any portion of its responsibilities and powers to any one (1) or more of its members and may delegate all or any part of its responsibilities and powers to any person or persons selected by it. Any such allocation or delegation may be revoked by the Committee at any time. Without limiting the generality of the foregoing, the Committee may delegate to one (1) or more officers of the Company, the authority to act on behalf of the Committee with respect to any matter, right, obligation, or election which is the responsibility of, or which is allocated to, the Committee herein, and which may be so delegated as a matter of law, except for grants of Awards to Directors. Notwithstanding the foregoing in this Section 3(c), it is intended that any action under the Plan intended to qualify for the exemptions provided by Rule 16b-3 will be taken only by the Board or by a committee or subcommittee of two (2) or more Eligible Directors. However, the fact that any member of such committee or subcommittee shall fail to qualify as an Eligible Director shall not invalidate any action that is otherwise valid under the Plan.

(d)   All decisions made by the Administrator pursuant to the provisions of the Plan shall be final, conclusive and binding on all persons, including the Company and the Participants. No member of the Board or the Committee, or any officer or employee of the Company or any Subsidiary thereof acting on behalf of the Board or the Committee, shall be personally liable for any action, omission,

Annex I-8

determination, or interpretation taken or made in good faith with respect to the Plan, and all members of the Board or the Committee and each and any officer or employee of the Company and of any Subsidiary thereof acting on their behalf shall, to the maximum extent permitted by law, be fully indemnified and protected by the Company in respect of any such action, omission, determination or interpretation.

Section 4.   Shares Reserved for Issuance Under the Plan and Limitations on Awards.

(a)   Subject to adjustment in accordance with Section 5 of the Plan, the Administrator is authorized to deliver with respect to Awards granted under the Plan an aggregate of [           ] shares of Common Stock, which includes (i) [  ] shares of Common Stock available for new issuances under the Plan, (ii) [  ] shares of Common Stock relating to a portion of outstanding stock options assumed by the Company in connection with the Going Public Transaction and (iii) [  ] shares of Common Stock relating to the Earn Out Awards (as such term is defined under the Merger Agreement);1 provided, that the total number of shares of Common Stock that will be reserved, and that may be issued, under the Plan will automatically increase on the first trading day of each calendar year, beginning with calendar year 2022, by a number of shares of Common Stock equal to three percent (3%) of the total number of Outstanding Common Stock on the last day of the prior calendar year. Notwithstanding the foregoing, the Administrator may act prior to January 1 of a given year to provide that there will be no such increase in the share reserve for that year or that the increase in the share reserve for such year will be a lesser number of shares of Common Stock than provided herein.

(b)   Notwithstanding anything herein to the contrary, the maximum number of shares of Common Stock subject to Awards granted during any fiscal year to any Non-Employee Director, taken together with any cash fees paid to such Non-Employee Director during the fiscal year with respect to such Director’s service as a Non-Employee Director, shall not exceed $[           ]2 (calculating the value of any such Awards based on the grant date Fair Market Value of such Awards for financial reporting purposes).

(c)   Shares of Common Stock issued under the Plan may, in whole or in part, be authorized but unissued shares of Common Stock or shares that shall have been or may be reacquired by the Company in the open market, in private transactions or otherwise. Any shares of Common Stock subject to an Award under the Plan that, after the Effective Date, are forfeited, canceled, settled or otherwise terminated without a distribution of shares of Common Stock to a Participant will thereafter be deemed to be available for Awards. In applying the immediately preceding sentence, if (i) shares of Common Stock otherwise issuable or issued in respect of, or as part of, any Award are withheld to cover taxes or any applicable Exercise Price, such shares shall be treated as having been issued under the Plan and shall not be available for issuance under the Plan, and (ii) any Share-settled Stock Appreciation Rights or Options are exercised, the aggregate number of shares of Common Stock subject to such Stock Appreciation Rights or Options shall be deemed issued under the Plan and shall not be available for issuance under the Plan. In addition, shares of Common Stock (x) tendered to exercise outstanding Options or other Awards, (y) withheld to cover applicable taxes on any Awards or (z) repurchased on the open market using Exercise Price proceeds shall not be available for issuance under the Plan. For the avoidance of doubt, (A) shares of Common Stock underlying Awards that are subject to the achievement of performance goals shall be counted against the share reserve based on the target value of such Awards unless and until such time as such Awards become vested and settled in shares of Common Stock, and (B) Awards that, pursuant to their terms, may be settled only in cash shall not count against the share reserve set forth in Section 4(a).

(d)   Substitute Awards shall not reduce the shares of Common Stock authorized for grant under the Plan. In the event that a company acquired by the Company or any Affiliate or with which the Company or any Affiliate combines has shares available under a pre-existing plan approved by stockholders and not adopted in contemplation of such acquisition or combination, the shares available

Note to Draft: Total number of shares referred to in clauses (i) and (ii) to equal 4% of shares of Outstanding Common Stock (as defined under the Plan) as of the Closing.

2

Note to Draft: Director compensation limit to be determined.

Annex I-9

for grant pursuant to the terms of such pre-existing plan (as adjusted, to the extent appropriate, using the exchange ratio or other adjustment or valuation ratio or formula used in such acquisition or combination to determine the consideration payable to the holders of common stock of the entities party to such acquisition or combination) may be used for Awards under the Plan and shall not reduce the shares of Common Stock authorized for grant under the Plan; provided, that Awards using such available shares of Common Stock shall not be made after the date awards or grants could have been made under the terms of the pre-existing plan, absent the acquisition or combination, and shall only be made to individuals who were not employed by or providing services to the Company or its Affiliates immediately prior to such acquisition or combination.

(e)   In the event that the Company or an Affiliate thereof consummates a transaction described in Code Section 424(a) (e.g., the acquisition of property or stock from an unrelated corporation), persons who become Employees or Directors in account of such transaction may be granted Substitute Awards in substitution for awards granted by their former employer, and any such substitute Options or Stock Appreciation Rights may be granted with an Exercise Price less than the Fair Market Value of a Share on the grant date thereof; provided, however, the grant of such substitute Option or Stock Appreciation Right shall not constitute a “modification” as defined in Code Section 424(h)(3) and the applicable Treasury regulations.

Section 5.   Equitable Adjustments.

In the event of any Change in Capitalization, including, without limitation, a Change in Control, an equitable substitution or proportionate adjustment shall be made, in each case, as may be determined by the Administrator, in its sole discretion, in (a) the aggregate number of shares of Common Stock reserved for issuance under the Plan, (b) the kind, number and Exercise Price subject to outstanding Options and Stock Appreciation Rights granted under the Plan; provided, however, that any such substitution or adjustment with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A, and (c) the kind, number and purchase price of shares of Common Stock subject to outstanding Restricted Shares or Other Share-Based Awards granted under the Plan, in each case as may be determined by the Administrator, in its sole discretion; provided, however, that any fractional shares of Common Stock resulting from the adjustment shall be eliminated. Such other equitable substitutions or adjustments shall be made as may be determined by the Administrator, in its sole discretion. Without limiting the generality of the foregoing, in connection with a Change in Capitalization, the Administrator may provide, in its sole discretion, for the cancellation of any outstanding Award granted hereunder (i) in exchange for payment in cash or other property having an aggregate Fair Market Value of the shares of Common Stock covered by such Award, reduced by the aggregate Exercise Price or purchase price thereof, if any, and (ii) with respect to any Awards for which the Exercise Price or purchase price per share of Common Stock is greater than or equal to the then current Fair Market Value per share of Common Stock, for no consideration. Notwithstanding anything contained in the Plan to the contrary, any adjustment with respect to an Incentive Stock Option due to an adjustment or substitution described in this Section 5 shall comply with the rules of Code Section 424(a), and in no event shall any adjustment be made which would render any Incentive Stock Option granted hereunder to be disqualified as an incentive stock option for purposes of Code Section 422. The Administrator’s determinations pursuant to this Section 5 shall be final, binding and conclusive.

Section 6.   Eligibility.

The Participants under the Plan shall be selected from time to time by the Administrator, in its sole discretion, from among Eligible Recipients.

Section 7.   Options.

(a)   General.   The Administrator may, in its sole discretion, grant Options to Participants. Solely with respect to Participants who are Employees, the Administrator may grant Incentive Stock Options, Nonqualified Stock Options or a combination of both. With respect to all other Participants, the Administrator may grant only Nonqualified Stock Options. Each Participant who is granted an Option shall enter into an Award Agreement with the Company, containing such terms and conditions as the

Annex I-10

Administrator shall determine, in its sole discretion, which Award Agreement shall specify whether the Option is an Incentive Stock Option or a Nonqualified Stock Option and shall set forth, among other things, the Exercise Price of the Option, the term of the Option and provisions regarding exercisability of the Option granted thereunder. The provisions of each Option need not be the same with respect to each Participant. More than one Option may be granted to the same Participant and be outstanding concurrently hereunder. Options granted under the Plan shall be subject to the terms and conditions set forth in this Section 7 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable and set forth in the applicable Award Agreement. The prospective recipient of an Option shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(b)   Limits on Incentive Stock Options.   If the Administrator grants Incentive Stock Options, then to the extent that the aggregate fair market value of shares of Common Stock with respect to which Incentive Stock Options are exercisable for the first time by any individual during any calendar year (under all plans of the Company) exceeds $100,000, such Options will be treated as Nonqualified Stock Options to the extent required by Code Section 422. Subject to Section 5, the maximum number of shares that may be issued pursuant to Options intended to be Incentive Stock Options is [           ] shares of Common Stock3 and, for the avoidance of doubt, such share limit shall not be subject to the annual adjustment provided in Section 4(b).

(c)   Exercise Price.   The Exercise Price of shares of Common Stock purchasable under an Option shall be determined by the Administrator in its sole discretion at the time of grant; provided, however, that (i) in no event shall the Exercise Price of an Option be less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant, and (ii) no Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) shall have an Exercise Price per Share less than one-hundred ten percent (110%) of the Fair Market Value of a Share on such date.

(d)   Option Term.   The maximum term of each Option shall be fixed by the Administrator, but in no event shall (i) an Option be exercisable more than ten (10) years after the date such Option is granted, and (ii) an Incentive Stock Option granted to a ten percent (10%) stockholder of the Company (within the meaning of Code Section 422(b)(6)) be exercisable more than five (5) years after the date such Option is granted. Each Option’s term is subject to earlier expiration pursuant to the applicable provisions in the Plan and the Award Agreement. Notwithstanding the foregoing, the Administrator shall have the authority to accelerate the exercisability of any outstanding Option at such time and under such circumstances as the Administrator, in its sole discretion, deems appropriate. Notwithstanding any contrary provision in this Plan (including, without limitation, Section 7(h)), if, on the date an outstanding Option would expire, the exercise of the Option, including by a “net exercise” or “cashless” exercise, would violate applicable securities laws or any insider trading policy maintained by the Company from time to time, the expiration date applicable to the Option will be extended, except to the extent such extension would violate Code Section 409A, to a date that is thirty (30) calendar days after the date the exercise of the Option would no longer violate applicable securities laws or any such insider trading policy.

(e)   Exercisability.   Each Option shall be exercisable at such time or times and subject to such terms and conditions, including the attainment of pre-established Performance Goals, as shall be determined by the Administrator in the applicable Award Agreement. The Administrator may also provide that any Option shall be exercisable only in installments, and the Administrator may waive such installment exercise provisions at any time, in whole or in part, based on such factors as the Administrator may determine in its sole discretion. Notwithstanding anything to the contrary contained herein, an Option may not be exercised for a fraction of a share.

Note to Draft: To be confirmed.

Annex I-11

(f)   Method of Exercise.   Options may be exercised in whole or in part by giving written notice of exercise to the Company specifying the number of shares of Common Stock to be purchased, accompanied by payment in full of the aggregate Exercise Price of the shares of Common Stock so purchased in cash or its equivalent, as determined by the Administrator. As determined by the Administrator, in its sole discretion, with respect to any Option or category of Options, payment in whole or in part may also be made (i) by means of consideration received under any cashless exercise procedure approved by the Administrator (including the withholding of shares of Common Stock otherwise issuable upon exercise), (ii) in the form of unrestricted shares of Common Stock already owned by the Participant which have a Fair Market Value on the date of surrender equal to the aggregate Exercise Price of the shares of Common Stock as to which such Option shall be exercised, (iii) any other form of consideration approved by the Administrator and permitted by applicable law, or (iv) any combination of the foregoing. In determining which methods a Participant may utilize to pay the Exercise Price, the Administrator may consider such factors as it determines are appropriate; provided, however, that with respect to Incentive Stock Options, all such discretionary determinations shall be made by the Administrator at the time of grant and specified in the Award Agreement.

(g)   Rights as Stockholder.    A Participant shall have no rights to dividends or any other rights of a stockholder with respect to the shares of Common Stock subject to an Option until the Participant has given written notice of the exercise thereof, has paid in full for such shares and has satisfied the requirements of Section 16 of the Plan.

(h)   Termination of Employment or Service.   Unless the applicable Award Agreement provides otherwise, in the event that the employment or service of a Participant with the Company and all Affiliates thereof shall terminate, the following terms and conditions shall apply:

(i)   In the event of the termination of a Participant’s employment or service by the Company without Cause or due to a resignation by the Participant for any reason, (A) Options granted to such Participant, to the extent that they are exercisable at the time of such termination, shall remain exercisable until the date that is ninety (90) days after such termination (with such period being extended to one (1) year after the date of such termination in the event of the Participant’s death during such ninety (90) day period), on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(ii)   In the event of the termination of a Participant’s employment or service as a result of the Participant’s Disability or death, (A) Options granted to such Participant, to the extent that they were exercisable at the time of such termination, shall remain exercisable until the date that is one (1) year after such termination, on which date they shall expire, and (B) Options granted to such Participant, to the extent that they were not exercisable at the time of such termination, shall expire at the close of business on the date of such termination. Notwithstanding the foregoing, no Option shall be exercisable after the expiration of its term.

(iii)   In the event of the termination of a Participant’s employment or service for Cause, all outstanding Options granted to such Participant shall expire at the commencement of business on the date of such termination.

(iv)   For purposes of determining which Options are exercisable upon termination of employment or service for purposes of this Section 7(h), Options that are not exercisable solely due to a blackout period shall be considered exercisable.

(v)   Notwithstanding anything herein to the contrary, an Incentive Stock Option may not be exercised more than three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability. In the event that an Option is exercisable following the date that is three (3) months following the date as of which a Participant ceases to be an Employee for any reason other than death or Disability, such Option shall be deemed to be a Nonqualified Stock Option.

Annex I-12

(i)   Other Change in Employment Status.   An Option may be affected, both with regard to vesting schedule and termination, by leaves of absence, changes from full-time to part-time employment, partial disability or other changes in the employment status or service of a Participant, as evidenced in a Participant’s Award Agreement.

(j)   Change in Control.   Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Options shall be subject to Section 12 of the Plan.

(k)   Automatic Exercise.   Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Option outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. In the sole discretion of the Administrator, payment of the exercise price of any such Option shall be made pursuant to Section 7(f)(i) or (ii), and the Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 7(k) shall not apply to an Option if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Option with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 7(k).

Section 8.   Stock Appreciation Rights.

(a)   General.   Stock Appreciation Rights may be granted either alone (“Free Standing Rights”) or in conjunction with all or part of any Option granted under the Plan (“Related Rights”). Any Related Right that relates to a Nonqualified Stock Option may be granted at the same time the Option is granted or at any time thereafter, but before the exercise or expiration of the Option. Any Related Right that relates to an Incentive Stock Option must be granted at the same time the Incentive Stock Option is granted. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Stock Appreciation Rights shall be made, the number of shares of Common Stock to be awarded, the price per Share, and all other conditions of Stock Appreciation Rights. Notwithstanding the foregoing, no Related Right may be granted for more shares of Common Stock than are subject to the Option to which it relates and any Stock Appreciation Right must be granted with an Exercise Price not less than the Fair Market Value of a share of Common Stock on the date of grant. The provisions of Stock Appreciation Rights need not be the same with respect to each Participant. Stock Appreciation Rights granted under the Plan shall be subject to the following terms and conditions set forth in this Section 8 and shall contain such additional terms and conditions, not inconsistent with the terms of the Plan, as the Administrator shall deem desirable, as set forth in the applicable Award Agreement.

(b)   Awards; Rights as Stockholder.   The prospective recipient of a Stock Appreciation Right shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Participants who are granted Stock Appreciation Rights shall have no rights as stockholders of the Company with respect to the grant or exercise of such rights.

(c)   Exercisability.

(i)   Stock Appreciation Rights that are Free Standing Rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii)   Stock Appreciation Rights that are Related Rights shall be exercisable only at such time or times and to the extent that the Options to which they relate shall be exercisable in accordance with the provisions of Section 7 above and this Section 8 of the Plan.

(d)   Payment Upon Exercise.

Annex I-13

(i)   Upon the exercise of a Free Standing Right, the Participant shall be entitled to receive up to, but not more than, that number of shares of Common Stock, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the price per share specified in the Free Standing Right multiplied by the number of shares of Common Stock in respect of which the Free Standing Right is being exercised.

(ii)   A Related Right may be exercised by a Participant by surrendering the applicable portion of the related Option. Upon such exercise and surrender, the Participant shall be entitled to receive up to, but not more than, that number of shares of Common Stock, determined using the Fair Market Value, equal in value to the excess of the Fair Market Value as of the date of exercise over the Exercise Price specified in the related Option multiplied by the number of shares of Common Stock in respect of which the Related Right is being exercised. Options which have been so surrendered, in whole or in part, shall no longer be exercisable to the extent the Related Rights have been so exercised.

(iii)   Notwithstanding the foregoing, the Administrator may determine to settle the exercise of a Stock Appreciation Right in cash (or in any combination of shares of Common Stock and cash).

(e)   Termination of Employment or Service.

(i)   Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Free Standing Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as shall be determined by the Administrator in the applicable Award Agreement.

(ii)   Subject to Section 8(f), in the event of the termination of employment or service with the Company and all Affiliates thereof of a Participant who has been granted one or more Related Rights, such rights shall be exercisable at such time or times and subject to such terms and conditions as set forth in the related Options.

(f)   Term.

(i)   The term of each Free Standing Right shall be fixed by the Administrator, but no Free Standing Right shall be exercisable more than ten (10) years after the date such right is granted.

(ii)   The term of each Related Right shall be the term of the Option to which it relates, but no Related Right shall be exercisable more than ten (10) years after the date such right is granted.

(g)   Change in Control.    Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Stock Appreciation Rights shall be subject to Section 12 of the Plan.

(h)   Automatic Exercise.   Unless otherwise provided by the Administrator in an Award Agreement or otherwise, or as otherwise directed by the Participant in writing to the Company, each vested and exercisable Stock Appreciation Right outstanding on the Automatic Exercise Date with an Exercise Price per Share that is less than the Fair Market Value per Share as of such date shall automatically and without further action by the Participant or the Company be exercised on the Automatic Exercise Date. The Company or any Affiliate shall deduct or withhold an amount sufficient to satisfy all taxes associated with such exercise in accordance with Section 16. Unless otherwise determined by the Administrator, this Section 8(h) shall not apply to a Stock Appreciation Right if the Participant’s employment or service has terminated on or before the Automatic Exercise Date. For the avoidance of doubt, no Stock Appreciation Right with an Exercise Price per Share that is equal to or greater the Fair Market Value per Share on the Automatic Exercise Date shall be exercised pursuant to this Section 8(h).

Section 9.   Restricted Shares.

(a)   General.   Each Award of Restricted Shares granted under the Plan shall be evidenced by an Award Agreement. Restricted Shares may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the time or times at which, grants of Restricted Shares shall be made; the number of shares of Common Stock to

Annex I-14

be awarded; the price, if any, to be paid by the Participant for the acquisition of Restricted Shares; the Restricted Period, if any, applicable to Restricted Shares; the Performance Goals (if any) applicable to Restricted Shares; and all other conditions of the Restricted Shares. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Shares in accordance with the terms of the grant. The terms and conditions applicable to the Restricted Shares need not be the same with respect to each Participant.

(b)   Awards and Certificates.   The prospective recipient of Restricted Shares shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date. Except as otherwise provided in herein, (i) each Participant who is granted an Award of Restricted Shares may, in the Company’s sole discretion, be issued a stock certificate in respect of such Restricted Shares; and (ii) any such certificate so issued shall be registered in the name of the Participant, and shall bear an appropriate legend referring to the terms, conditions, and restrictions applicable to any such Award. The Company may require that the stock certificates, if any, evidencing Restricted Shares granted hereunder be held in the custody of the Company until the restrictions thereon shall have lapsed, and that, as a condition of any award of Restricted Shares, the Participant shall have delivered a stock power, endorsed in blank, relating to the shares of Common Stock covered by such Award. Notwithstanding anything in the Plan to the contrary, any Restricted Shares (whether before or after any vesting conditions have been satisfied) may, in the Company’s sole discretion, be issued in uncertificated form pursuant to the customary arrangements for issuing shares in such form.

(c)   Restrictions and Conditions.   The Restricted Shares granted pursuant to this Section 9 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or thereafter:

(i)   The Restricted Shares shall be subject to the restrictions on transferability set forth in the Award Agreement and in the Plan.

(ii)   The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(iii)   Subject to this Section 9(c)(iii), the Participant shall generally have the rights of a stockholder of the Company with respect to Restricted Shares during the Restricted Period. In the Administrator’s discretion and as provided in the applicable Award Agreement, a Participant may be entitled to dividends or dividend equivalents on an Award of Restricted Shares, which will be payable in accordance with the terms of such grant as determined by the Administrator in accordance with Section 18 of the Plan. Certificates for unrestricted Shares may, in the Company’s sole discretion, be delivered to the Participant only after the Restricted Period has expired without forfeiture in respect of such Restricted Shares, except as the Administrator, in its sole discretion, shall otherwise determine.

(iv)   The rights of Participants granted Restricted Shares upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d)   Change in Control.   Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Shares shall be subject to Section 12 of the Plan.

Section 10.   Restricted Stock Units.

(a)   General.   Restricted Stock Units may be issued either alone or in addition to other Awards granted under the Plan. The Administrator shall determine the Eligible Recipients to whom, and the

Annex I-15

time or times at which, grants of Restricted Stock Units shall be made; the number of Restricted Stock Units to be awarded; the Restricted Period, if any, applicable to Restricted Stock Units; the Performance Goals (if any) applicable to Restricted Stock Units; and all other conditions of the Restricted Stock Units. If the restrictions, Performance Goals and/or conditions established by the Administrator are not attained, a Participant shall forfeit his or her Restricted Stock Units in accordance with the terms of the grant. The provisions of Restricted Stock Units need not be the same with respect to each Participant.

(b)   Award Agreement.   The prospective recipient of Restricted Stock Units shall not have any rights with respect to any such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c)   Restrictions and Conditions.   The Restricted Stock Units granted pursuant to this Section 10 shall be subject to the following restrictions and conditions and any additional restrictions or conditions as determined by the Administrator at the time of grant or, subject to Code Section 409A, thereafter:

(i)   The Administrator may, in its sole discretion, provide for the lapse of restrictions in installments and may accelerate or waive such restrictions in whole or in part based on such factors and such circumstances as the Administrator may determine, in its sole discretion, including, but not limited to, the attainment of certain Performance Goals, the Participant’s termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof, or the Participant’s death or Disability.

(ii)   Participants holding Restricted Stock Units shall have no voting rights. A Restricted Stock Unit may, at the Administrator’s discretion, carry with it a right to dividend equivalents, subject to Section 18 of the Plan. Such right would entitle the holder to be credited with an amount equal to all cash dividends paid on one Share while the Restricted Stock Unit is outstanding. The Administrator, in its discretion, may grant dividend equivalents from the date of grant or only after a Restricted Stock Unit is vested.

(iii)   The rights of Participants granted Restricted Stock Units upon termination of employment or service as a Non-Employee Director or Consultant of the Company or an Affiliate thereof terminates for any reason during the Restricted Period shall be set forth in the Award Agreement.

(d)   Settlement of Restricted Stock Units.   Settlement of vested Restricted Stock Units shall be made to Participants in the form of shares of Common Stock, unless the Administrator, in its sole discretion, provides for the payment of the Restricted Stock Units in cash (or partly in cash and partly in shares of Common Stock) equal to the value of the shares of Common Stock that would otherwise be distributed to the Participant.

(e)   Change in Control.   Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Restricted Stock Units shall be subject to Section 12 of the Plan.

Section 11.   Other Share-Based or Cash-Based Awards.

(a)   The Administrator is authorized to grant Awards to Participants in the form of Other Share-Based Awards or Other Cash-Based Awards, as deemed by the Administrator to be consistent with the purposes of the Plan and as evidenced by an Award Agreement. The Administrator shall determine the terms and conditions of such Awards, consistent with the terms of the Plan, at the date of grant or thereafter, including any Performance Goals and performance periods. Shares of Common Stock or other securities or property delivered pursuant to an Award in the nature of a purchase right granted under this Section 11 shall be purchased for such consideration, paid for at such times, by such methods, and in such forms, including, without limitation, shares of Common Stock, other Awards, notes or other property, as the Administrator shall determine, subject to any required corporate action.

Annex I-16

(b)   The prospective recipient of an Other Share-Based Award or Other Cash-Based Award shall not have any rights with respect to such Award, unless and until such recipient has received an Award Agreement and, if required by the Administrator in the Award Agreement, executed and delivered a fully executed copy thereof to the Company, within a period of sixty (60) days (or such other period as the Administrator may specify) after the award date.

(c)   Notwithstanding anything herein to the contrary, upon a Change in Control, all outstanding Other Share-Based Awards and Other Cash-Based Awards shall be subject to Section 12 of the Plan.

Section 12.   Change in Control.

The Administrator may provide in the applicable Award Agreement that an Award will vest on an accelerated basis upon the Participant’s termination of employment or service in connection with a Change in Control or upon the occurrence of any other event that the Administrator may set forth in the Award Agreement. If the Company is a party to an agreement that is reasonably likely to result in a Change in Control, such agreement may provide for: (i) the continuation of any Award by the Company, if the Company is the surviving corporation; (ii) the assumption of any Award by the surviving corporation or its parent or subsidiary; (iii) the substitution by the surviving corporation or its parent or subsidiary of equivalent awards for any Award, provided, however, that any such substitution with respect to Options and Stock Appreciation Rights shall occur in accordance with the requirements of Code Section 409A; or (iv) settlement of any Award for the Change in Control Price (less, to the extent applicable, the per share exercise or grant price), or, if the per share exercise or grant price equals or exceeds the Change in Control Price or if the Administrator determines that Award cannot reasonably become vested pursuant to its terms, such Award shall terminate and be canceled without consideration. To the extent that Restricted Shares, Restricted Stock Units or other Awards settle in shares of Common Stock in accordance with their terms upon a Change in Control, such shares of Common Stock shall be entitled to receive as a result of the Change in Control transaction the same consideration as the shares of Common Stock held by stockholders of the Company as a result of the Change in Control transaction. For purposes of this Section 12, “Change in Control Price” shall mean (A) the price per Share paid to stockholders of the Company in the Change in Control transaction, or (B) the Fair Market Value of a Share upon a Change in Control, as determined by the Administrator. To the extent that the consideration paid in any such Change in Control transaction consists all or in part of securities or other non-cash consideration, the value of such securities or other non-cash consideration shall be determined in good faith by the Administrator.

Section 13.   Amendment and Termination.

(a)   The Board or the Committee may amend, alter or terminate the Plan, but no amendment, alteration, or termination shall be made that would adversely alter or impair the rights of a Participant under any Award theretofore granted without such Participant’s prior written consent.

(b)   Notwithstanding the foregoing, (i) approval of the Company’s stockholders shall be obtained for any amendment that would require such approval in order to satisfy the requirements of Code Section 422, if applicable, any rules of the stock exchange on which the shares of Common Stock are traded or other applicable law, and (ii) without stockholder approval to the extent required by the rules of any applicable national securities exchange or inter-dealer quotation system on which the shares of Common Stock are listed or quoted, except as otherwise permitted under Section 5 of the Plan, (A) no amendment or modification may reduce the Exercise Price of any Option or Stock Appreciation Right, (B) the Administrator may not cancel any outstanding Option or Stock Appreciation Right and replace it with a new Option or Stock Appreciation Right, another Award or cash and (C) the Administrator may not take any other action that is considered a “repricing” for purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer quotation system.

(c)   Subject to the terms and conditions of the Plan and Code Section 409A, the Administrator may modify, extend or renew outstanding Awards under the Plan, or accept the surrender of outstanding Awards (to the extent not already exercised) and grant new Awards in substitution of them (to the extent not already exercised).

Annex I-17

(d)   Notwithstanding the foregoing, no alteration, modification or termination of an Award will, without the prior written consent of the Participant, adversely alter or impair any rights or obligations under any Award already granted under the Plan.

Section 14.   Unfunded Status of Plan.

The Plan is intended to constitute an “unfunded” plan for incentive compensation. Neither the Company, the Board nor the Committee shall be required to establish any special or separate fund or to segregate any assets to assure the performance of its obligations under the Plan. With respect to any payments not yet made or shares of Common Stock not yet transferred to a Participant by the Company, nothing contained herein shall give any such Participant any rights that are greater than those of a general unsecured creditor of the Company.

Section 15.   Deferrals of Payment.

To the extent permitted by applicable law, the Administrator, in its sole discretion, may determine that the delivery of shares of Common Stock or the payment of cash, upon the exercise, vesting or settlement of all or a portion of any Award, shall be deferred. The Administrator may also, in its sole discretion, establish one or more programs under the Plan to permit selected Participants the opportunity to elect to defer receipt of any such consideration, including any applicable election procedures, the timing of such elections, the mechanisms for payments of amounts, shares or other consideration so deferred, and such other terms, conditions, rules and procedures that the Administrator deems advisable for the administration of any such deferral program. Deferrals by Participants (or deferred settlement or payment required by the Administrator) shall be made in accordance with Code Section 409A, if applicable, and any other applicable law.

Section 16.   Withholding Taxes.

Each Participant shall, no later than the date as of which the value of an Award first becomes includible in the gross income of such Participant for federal, state and/or local income tax purposes, pay to the Company, or make arrangements satisfactory to the Administrator regarding payment of, any federal, state, or local taxes of any kind, domestic or foreign, required by law or regulation to be withheld with respect to the Award. The obligations of the Company under the Plan shall be conditional on the making of such payments or arrangements, and the Company shall, to the extent permitted by law, have the right to deduct any such taxes from any payment of any kind otherwise due to such Participant. Whenever cash is to be paid pursuant to an Award granted hereunder, the Company shall have the right to deduct therefrom an amount sufficient to satisfy any federal, state and local withholding tax requirements related thereto. Whenever shares of Common Stock are to be delivered pursuant to an Award, the Company shall have the right to require the Participant to remit to the Company in cash an amount sufficient to satisfy any related federal, state and local taxes, domestic or foreign, to be withheld and applied to the tax obligations. With the approval of the Administrator, a Participant may satisfy the foregoing requirement by electing to have the Company withhold from delivery of shares of Common Stock or by delivering already owned unrestricted shares of Common Stock, in each case, having a value equal to the amount required to be withheld or other greater amount not exceeding the maximum statutory rate required to be collected on the transaction under applicable law, as applicable to the Participant, if such other greater amount would not, as determined by the Administrator, result in adverse financial accounting treatment (including in connection with the effectiveness of FASB Accounting Standards Update 2016-09). Such shares of Common Stock shall be valued at their Fair Market Value on the date of which the amount of tax to be withheld is determined. Fractional share amounts shall be settled in cash. Such an election may be made with respect to all or any portion of the shares of Common Stock to be delivered pursuant to an Award. The Company may also use any other method of obtaining the necessary payment or proceeds, as permitted by law, to satisfy its withholding obligation with respect to any Option or other Award.

Section 17.   Certain Forfeitures.

The Administrator may specify in an Award Agreement that the Participant’s rights, payments and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture or recoupment upon

Annex I-18

the occurrence of certain events, in addition to the applicable vesting conditions of an Award. Such events may include, without limitation, breach of any non-competition, non-solicitation, confidentiality, or other restrictive covenants that are contained in an Award Agreement or that are otherwise applicable to the Participant, a termination of the Participant’s employment for Cause, or other conduct by the Participant that is detrimental to the business or reputation of the Company and its Subsidiaries and/or its Affiliates.

Section 18.   Dividends; Dividend Equivalents.

Notwithstanding anything in this Plan to the contrary, to the extent that an Award contains a right to receive dividends or dividend equivalents while such Award remains unvested, such dividends or dividend equivalents will be accumulated and paid once and to the extent that the underlying Award vests.

Section 19.   Non-United States Employees.

Without amending the Plan, the Administrator may grant Awards to eligible persons residing in non-United States jurisdictions on such terms and conditions different from those specified in the Plan, including the terms of any award agreement or plan, adopted by the Company or any Subsidiary thereof to comply with, or take advantage of favorable tax or other treatment available under, the laws of any non-United States jurisdiction, as may in the judgment of the Administrator be necessary or desirable to foster and promote achievement of the purposes of the Plan and, in furtherance of such purposes the Administrator may make such modifications, amendments, procedures, sub-plans and the like as may be necessary or advisable to comply with provisions of laws in other countries or jurisdictions in which the Company or its Subsidiaries operates or has employees.

Section 20.   Transfer of Awards.

No purported sale, assignment, mortgage, hypothecation, transfer, charge, pledge, encumbrance, gift, transfer in trust (voting or other) or other disposition of, or creation of a security interest in or lien on, any Award or any agreement or commitment to do any of the foregoing (each, a “Transfer”) by any holder thereof in violation of the provisions of the Plan or an Award Agreement will be valid, except with the prior written consent of the Administrator, which consent may be granted or withheld in the sole discretion of the Administrator, and other than by will or by the laws of descent and distribution. Any purported Transfer of an Award or any economic benefit or interest therein in violation of the Plan or an Award Agreement shall be null and void ab initio, and shall not create any obligation or liability of the Company, and any person purportedly acquiring any Award or any economic benefit or interest therein transferred in violation of the Plan or an Award Agreement shall not be entitled to be recognized as a holder of such shares of Common Stock. Unless otherwise determined by the Administrator in accordance with the provisions of the immediately preceding sentence, an Option may be exercised, during the lifetime of the Participant, only by the Participant or, during any period during which the Participant is under a legal disability, by the Participant’s guardian or legal representative. Under no circumstances will a Participant be permitted to transfer an Option or Stock Appreciation Right to a third-party financial institution without prior stockholder approval.

Section 21.   Continued Employment.

The adoption of the Plan shall not confer upon any Eligible Recipient any right to continued employment or service with the Company or an Affiliate thereof, as the case may be, nor shall it interfere in any way with the right of the Company or an Affiliate thereof to terminate the employment or service of any of its Eligible Recipients at any time.

Section 22.   Effective Date.

The Plan will be effective as of the date of consummation of the transactions contemplated by the Merger Agreement so long as the Plan has been approved by the Company’s stockholders. The Plan will be unlimited in duration and, in the event of Plan termination, will remain in effect as long as any shares of Common Stock awarded under it are outstanding and not fully vested; provided, however, that no Awards will be made under the Plan on or after the tenth anniversary of the Effective Date; provided further, that in no

Annex I-19

event may an Incentive Stock Option be granted more than ten years after the earlier of (a) the date of the adoption of the Plan by the Board or (b) the Effective Date.

Section 23.   Code Section 409A.

The intent of the parties is that payments and benefits under the Plan be either exempt from Code Section 409A or comply with Code Section 409A to the extent subject thereto, and, accordingly, to the maximum extent permitted, the Plan shall be interpreted and be administered consistent with such intent. Any payments described in the Plan that are due within the “short-term deferral period” as defined in Code Section 409A shall not be treated as deferred compensation unless applicable law requires otherwise. Notwithstanding anything to the contrary in the Plan, to the extent required in order to avoid accelerated taxation and/or tax penalties under Code Section 409A, amounts that would otherwise be payable and benefits that would otherwise be provided upon a “separation from service” to a Participant who is a “specified employee” shall be paid on the first business day after the date that is six (6) months following the Participant’s separation from service (or upon the Participant’s death, if earlier). In addition, for purposes of the Plan, each amount to be paid or benefit to be provided to the Participant pursuant to the Plan, which constitute deferred compensation subject to Code Section 409A, shall be construed as a separate identified payment for purposes of Code Section 409A. Nothing contained in the Plan or an Award Agreement shall be construed as a guarantee of any particular tax effect with respect to an Award. The Company does not guarantee that any Awards provided under the Plan will be exempt from or in compliance with the provisions of Code Section 409A, and in no event will the Company be liable for any or all portion of any taxes, penalties, interest or other expenses that may be incurred by a Participant on account of any Award being subject to, but not in compliance with, Code Section 409A.

Section 24.   Compliance with Laws.

(a)   The obligation of the Company to settle Awards in shares of Common Stock or other consideration shall be subject to (i) all applicable laws, rules, and regulations, (ii) such approvals as may be required by governmental agencies or the applicable national securities exchange on which the shares of Common Stock may be admitted, and (iii) policies maintained by the Company from time to time in order to comply with applicable laws, rules, regulations and corporate governance requirements, including, without limitation, with respect to insider trading restrictions. Notwithstanding any terms or conditions of any Award to the contrary, the Company shall be under no obligation to offer to sell or to sell, and shall be prohibited from offering to sell or selling, any shares of Common Stock pursuant to an Award unless such shares have been properly registered for sale pursuant to the Securities Act with the Securities and Exchange Commission or unless the Company has received an opinion of counsel (if the Company has requested such an opinion), satisfactory to the Company, that such shares of Common Stock may be offered or sold without such registration pursuant to an available exemption therefrom and the terms and conditions of such exemption have been fully complied with. The Company shall be under no obligation to register for sale under the Securities Act any of the shares of Common Stock to be offered or sold under the Plan. The Administrator shall have the authority to provide that all shares of Common Stock or other securities of the Company issued under the Plan shall be subject to such stop transfer orders and other restrictions as the Committee may deem advisable under the Plan, the applicable Award Agreement, the federal securities laws, or the rules, regulations and other requirements of the Securities and Exchange Commission, any securities exchange or inter-dealer quotation system on which the securities of the Company are listed or quoted and any other applicable federal, state, local or non-U.S. laws, rules, regulations and other requirements, and the Administrator may cause a legend or legends to be put on certificates representing shares of Common Stock or other securities of the Company issued under the Plan to make appropriate reference to such restrictions or may cause such shares of Common Stock or other securities of the Company issued under the Plan in book-entry form to be held subject to the Company’s instructions or subject to appropriate stop-transfer orders. Notwithstanding any provision in the Plan to the contrary, the Committee reserves the right to add any additional terms or provisions to any Award granted under the Plan that it, in its sole discretion, deems necessary or advisable in order that such Award complies with the legal requirements of any governmental entity to whose jurisdiction the Award is subject.

Annex I-20

(b)   The Administrator may cancel an Award or any portion thereof if it determines, in its sole discretion, that legal or contractual restrictions and/or blockage and/or other market considerations would make the Company’s acquisition of shares of Common Stock from the public markets, the Company’s issuance of shares of Common Stock to the Participant, the Participant’s acquisition of shares of Common Stock from the Company and/or the Participant’s sale of shares of Common Stock to the public markets, illegal, impracticable or inadvisable. If the Administrator determines to cancel all or any portion of an Award in accordance with the foregoing, the Company shall, subject to any limitations or reductions as may be necessary to comply with Code Section 409A, (i) pay to the Participant an amount equal to the excess of (A) the aggregate Fair Market Value of the shares of Common Stock subject to such Award or portion thereof canceled (determined as of the applicable exercise date, or the date that the shares of Common Stock would have been vested or issued, as applicable), over (B) the aggregate Exercise Price (in the case of an Option or Stock Appreciation Right) or any amount payable as a condition of issuance of shares of Common Stock (in the case of any other Award), and such amount shall be delivered to the Participant as soon as practicable following the cancellation of such Award or portion thereof, or (ii) in the case of Restricted Shares, Restricted Stock Units or Other Share-Based Awards, provide the Participant with a cash payment or equity subject to deferred vesting and delivery consistent with the vesting restrictions applicable to such Restricted Shares, Restricted Stock Units or Other Share-Based Awards, or the underlying shares of Common Stock in respect thereof.

Section 25.   Clawback/Recovery.

The Plan and all Awards issued hereunder shall be subject to any compensation recovery and/or recoupment policy adopted by the Company to comply with applicable law, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act, or to comport with good corporate governance practices, as such policies may be amended from time to time. No recovery of compensation under such a clawback policy will be an event giving rise to a right to resign for “good reason” or “constructive termination” ​(or similar term) under any agreement with the Company or a Subsidiary.

Section 26.   Governing Law.

The Plan shall be governed by and construed in accordance with the laws of the State of Delaware, without giving effect to principles of conflicts of law of such state.

Section 27.   Plan Document Controls.

The Plan and each Award Agreement together constitute the entire agreement with respect to the subject matter hereof and thereof; provided, that in the event of any inconsistency between the Plan and such Award Agreement, the terms and conditions of the Plan shall control.

Annex I-21

PART II
INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.   Indemnification of Directors and Officers.

Our amended and restated certificate of incorporation provides that all of our directors, officers, employees and agents shall be entitled to be indemnified by us to the fullest extent permitted by Section 145 of the DGCL. Section 145 of the DGCL concerning indemnification of officers, directors, employees and agents is set forth below.

Section 145. Indemnification of officers, directors, employees and agents; insurance.

(a)

A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation) by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

(b)

A corporation shall have power to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees) actually and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

(c)

(1) To the extent that a present or former director or officer of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein, such person shall be indemnified against expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection therewith. For indemnification with respect to any act or omission occurring after December 31, 2020, references to “officer” for purposes of this paragraphs (c)(1) and (2) of this section shall mean only a person who at the time of such act or omission is deemed to have consented to service by the delivery of process to the registered agent of the corporation pursuant to § 3114(b) of Title 10 (for purposes of this sentence only, treating residents of this State as if they were nonresidents to apply § 3114(b) of Title 10 to this sentence). (2) The corporation may indemnify any other person who is not a present or former director or officer of the corporation against expenses (including attorneys’ fees) actually and reasonably incurred by such person to

II-1

the extent he or she has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in subsections (a) and (b) of this section, or in defense of any claim, issue or matter therein.

(d)

Any indemnification under subsections (a) and (b) of this section (unless ordered by a court) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the present or former director, officer, employee or agent is proper in the circumstances because the person has met the applicable standard of conduct set forth in subsections (a) and (b) of this section. Such determination shall be made, with respect to a person who is a director or officer of the corporation at the time of such determination, (1) by a majority vote of the directors who are not parties to such action, suit or proceeding, even though less than a quorum, or (2) by a committee of such directors designated by majority vote of such directors, even though less than a quorum, or (3) if there are no such directors, or if such directors so direct, by independent legal counsel in a written opinion, or (4) by the stockholders.

(e)

Expenses (including attorneys’ fees) incurred by an officer or director of the corporation in defending any civil, criminal, administrative or investigative action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of such director or officer to repay such amount if it shall ultimately be determined that such person is not entitled to be indemnified by the corporation as authorized in this section. Such expenses (including attorneys’ fees) incurred by former directors or other employees and agents of the corporation or by persons serving at the request of the corporation as directors, officers, employees or agents of another corporation, partnership, joint venture, trust or other enterprise may be so paid upon such terms and conditions, if any, as the corporation deems appropriate.

(f)

The indemnification and advancement of expenses provided by, or granted pursuant to, the other subsections of this section shall not be deemed exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any bylaw, agreement, vote of stockholders or disinterested directors or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office. A right to indemnification or to advancement of expenses arising under a provision of the certificate of incorporation or a bylaw shall not be eliminated or impaired by an amendment to or repeal or elimination of the certificate of incorporation or the bylaws after the occurrence of the act or omission that is the subject of the civil, criminal, administrative or investigative action, suit or proceeding for which indemnification or advancement of expenses is sought, unless the provision in effect at the time of such act or omission explicitly authorizes such elimination or impairment after such action or omission has occurred.

(g)

A corporation shall have power to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted against such person and incurred by such person in any such capacity, or arising out of such person’s status as such, whether or not the corporation would have the power to indemnify such person against such liability under this section.

(h)

For purposes of this section, references to “the corporation” shall include, in addition to the resulting corporation, any constituent corporation (including any constituent of a constituent) absorbed in a consolidation or merger which, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, and employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation, or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, shall stand in the same position under this section with respect to the resulting or surviving corporation as such person would have with respect to such constituent corporation if its separate existence had continued.

II-2

(i)

For purposes of this section, references to “other enterprises” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a person with respect to any employee benefit plan; and references to “serving at the request of the corporation” shall include any service as a director, officer, employee or agent of the corporation which imposes duties on, or involves services by, such director, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries; and a person who acted in good faith and in a manner such person reasonably believed to be in the interest of the participants and beneficiaries of an employee benefit plan shall be deemed to have acted in a manner “not opposed to the best interests of the corporation” as referred to in this section.

(j)

The indemnification and advancement of expenses provided by, or granted pursuant to, this section shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

(k)

The Court of Chancery is hereby vested with exclusive jurisdiction to hear and determine all actions for advancement of expenses or indemnification brought under this section or under any by-law, agreement, vote of stockholders or disinterested directors, or otherwise. The Court of Chancery may summarily determine a corporation’s obligation to advance expenses (including attorneys’ fees).

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to our directors, officers, and controlling persons pursuant to the foregoing provisions, or otherwise, we have been advised that, in the opinion of the SEC, such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment of expenses incurred or paid by a director, officer or controlling person in a successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, we will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to the court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

In accordance with Section 102(b)(7) of the DGCL, our amended and restated certificate of incorporation, provides that no director shall be personally liable to us or any of our stockholders for monetary damages resulting from breaches of their fiduciary duty as directors, except to the extent such limitation on or exemption from liability is not permitted under the DGCL. The effect of this provision of our amended and restated certificate of incorporation is to eliminate our rights and those of our stockholders (through stockholders’ derivative suits on our behalf) to recover monetary damages against a director for breach of the fiduciary duty of care as a director, including breaches resulting from negligent or grossly negligent behavior, except, as restricted by Section 102(b)(7) of the DGCL. However, this provision does not limit or eliminate our rights or the rights of any stockholder to seek non-monetary relief, such as an injunction or rescission, in the event of a breach of a director’s duty of care.

If the DGCL is amended to authorize corporate action further eliminating or limiting the liability of directors, then, in accordance with our amended and restated certificate of incorporation, the liability of our directors to us or our stockholders will be eliminated or limited to the fullest extent authorized by the DGCL, as so amended. Any repeal or amendment of provisions of our amended and restated certificate of incorporation limiting or eliminating the liability of directors, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to further limit or eliminate the liability of directors on a retroactive basis.

Our amended and restated certificate of incorporation provides that we will, to the fullest extent authorized or permitted by applicable law, indemnify our current and former officers and directors, as well as those persons who, while directors or officers of our corporation, are or were serving as directors, officers, employees or agents of another entity, trust or other enterprise, including service with respect to an employee benefit plan, in connection with any threatened, pending or completed proceeding, whether civil,

II-3

criminal, administrative or investigative, against all expense, liability and loss (including, without limitation, attorney’s fees, judgments, fines, ERISA excise taxes and penalties and amounts paid in settlement) reasonably incurred or suffered by any such person in connection with any such proceeding.

Notwithstanding the foregoing, a person eligible for indemnification pursuant to our amended and restated certificate of incorporation will be indemnified by us in connection with a proceeding initiated by such person only if such proceeding was authorized by our board of directors, except for proceedings to enforce rights to indemnification.

The right to indemnification which is conferred by our amended and restated certificate of incorporation is a contract right that includes the right to be paid by us the expenses incurred in defending or otherwise participating in any proceeding referenced above in advance of its final disposition, provided, however, that if the DGCL requires, an advancement of expenses incurred by our officer or director (solely in the capacity as an officer or director of our corporation) will be made only upon delivery to us of an undertaking, by or on behalf of such officer or director, to repay all amounts so advanced if it is ultimately determined that such person is not entitled to be indemnified for such expenses under our amended and restated certificate of incorporation or otherwise.

The rights to indemnification and advancement of expenses will not be deemed exclusive of any other rights which any person covered by our amended and restated certificate of incorporation may have or hereafter acquire under law, our amended and restated certificate of incorporation, our bylaws, an agreement, vote of stockholders or disinterested directors, or otherwise.

Any repeal or amendment of provisions of our amended and restated certificate of incorporation affecting indemnification rights, whether by our stockholders or by changes in law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing at the time of such repeal or amendment or adoption of such inconsistent provision with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision. Our amended and restated certificate of incorporation also permits us, to the extent and in the manner authorized or permitted by law, to indemnify and to advance expenses to persons other that those specifically covered by our amended and restated certificate of incorporation.

Our bylaws include the provisions relating to advancement of expenses and indemnification rights consistent with those which will be set forth in our amended and restated certificate of incorporation. In addition, our bylaws provide for a right of indemnity to bring a suit in the event a claim for indemnification or advancement of expenses is not paid in full by us within a specified period of time. Our bylaws also permit us to purchase and maintain insurance, at our expense, to protect us and/or any director, officer, employee or agent of our corporation or another entity, trust or other enterprise against any expense, liability or loss, whether or not we would have the power to indemnify such person against such expense, liability or loss under the DGCL.

Any repeal or amendment of provisions of our bylaws affecting indemnification rights, whether by our board of directors, stockholders or by changes in applicable law, or the adoption of any other provisions inconsistent therewith, will (unless otherwise required by law) be prospective only, except to the extent such amendment or change in law permits us to provide broader indemnification rights on a retroactive basis, and will not in any way diminish or adversely affect any right or protection existing thereunder with respect to any act or omission occurring prior to such repeal or amendment or adoption of such inconsistent provision.

We have entered into indemnification agreements with each of our officers and directors. These agreements require us to indemnify these individuals to the fullest extent permitted under Delaware law against liabilities that may arise by reason of their service to us, and to advance expenses incurred as a result of any proceeding against them as to which they could be indemnified.

Item 22.   Undertakings.

A.

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)

To include any prospectus required by Section 10(a)(3) of the Securities Act.

(ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

(iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

B.

That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

C.

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

D.

That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

E.

That, for the purpose of determining liability of the registrant under the Securities Act to any

II-6

purchaser in the initial distribution of the securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i)

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

(ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

(iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

(iv)

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

F.

That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

G.

That every prospectus (i) that is filed pursuant to paragraph (F) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

H.

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

I.

To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.
