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.

(a) Sponsor hereby irrevocably and unconditionally agrees that, from and after the date hereof and until the earlier of (i) the Closing or (ii) the valid termination of this Agreement pursuant to Section 7 (the “Effective Period”), the Sponsor hereby agrees that at any meeting of the stockholders of SPAC (whether annual or extraordinary and whether or not adjourned or postponed or any other meeting of SPAC), however called, on any written resolution, and in any action by written consent or resolution, in each case of the shareholders of SPAC (collectively, “such meeting or written consent”), Sponsor shall, solely in its capacity as a shareholder of SPAC do the following:

when such meeting is held, appear at such meeting (in person or by proxy) or otherwise cause the Subject SPAC Equity Securities to be counted as present thereat for the purpose of establishing a quorum;

ii.

vote the Subject SPAC Equity Securities (or execute and return an action by written consent), or cause the Subject SPAC Equity Securities to be voted (or validly execute and return and cause such consent to be granted with respect to), at such meeting or written consent (including the SPAC Stockholders Meeting), in favor of the Required Transaction Proposals and the transactions contemplated by the Business Combination Agreement (collectively, the “Transactions”), including with respect to any matter in furtherance of the Transactions or by any of the Ancillary Documents for which a vote or approval of the SPAC shareholders is required (the “Transaction Approvals”);

iii.

vote against any action, proposal, transaction or agreement that would result in a breach in any respect of any representation, warranty, covenant, obligation or agreement of SPAC or Merger Sub contained in the Business Combination Agreement, that conflicts or materially impedes or interferes with any Required Transaction Proposals, including any SPAC Acquisition Proposal, or that would adversely affect or delay the consummation of the transactions contemplated by the Business Combination Agreement;

iv.

validly execute and deliver to SPAC, on (or effective as of) the fifth (5th) Business Day following the date that the Proxy Statement/Prospectus is disseminated by SPAC to SPAC’s stockholders (following the date that the Registration Statement/Proxy Statement becomes effective), a properly completed voting proxy in the form distributed by or on behalf of SPAC in favor of the Required Transaction Proposals and any other proposals set forth in the Registration Statement/Proxy Statement; and

except as set forth in the Proxy Statement/Registration Statement, vote against the following actions or proposals: (A) any proposal in opposition to approval of the Business Combination Agreement or in competition with or materially inconsistent with the Business Combination Agreement; (B) any SPAC Acquisition Proposal and (C) (x) any amendment of the Amended Certificate of Incorporation or bylaws of SPAC or (y) any other action or proposal involving SPAC any of its subsidiaries that is intended, or would reasonably be expected, to prevent, impede, interfere with, delay, postpone or adversely affect the Transactions in any material respect or would reasonably be expected to result in any of SPAC’s closing conditions or obligations under the Business Combination Agreement not being satisfied.

(b) During the Effective Period, Sponsor shall not take, nor shall it permit any of its Affiliates or any of its or their respective representatives to take, whether directly or indirectly, any action to (i) solicit, initiate, continue or engage in discussions or negotiations with, or enter into any agreement with, or encourage, respond, provide information to or commence due diligence with respect to, any Person (other than the Company, its shareholders and/or any of their Affiliates or representatives), concerning, relating

to or which is intended or is reasonably likely to give rise to or result in, any SPAC Acquisition Proposal or (ii) approve, endorse or recommend, or make any public statement approving, endorsing or recommending, any SPAC Acquisition Proposal, in the case of each of clauses (i) and (ii), other than a SPAC Acquisition Proposal with the Company, its shareholders and their respective Affiliates and representatives. Sponsor shall and shall cause its Affiliates and representatives to, immediately cease any and all existing discussions or negotiations with any Person conducted prior to the date hereof with respect to, or which is reasonably likely to give rise to or result in, a SPAC Acquisition Proposal, other than with the Company, its equityholders or their respective controlled Affiliates. If Sponsor receives any inquiry or proposal with respect to a SPAC Acquisition Proposal, then Sponsor shall promptly (and in no event later than twenty-four (24) hours after Sponsor becomes aware of such inquiry or proposal) (i) notify such person in writing that SPAC is subject to an exclusivity agreement with respect to the Merger that prohibits Sponsor from considering such inquiry or proposal and (ii) advise the Company of such inquiry or proposal.

2. Waivers.

(a) During the Effective Period, the Sponsor (for itself, and for its successors, heirs and assigns) hereby waives, subject to, and conditioned upon, the occurrence of the Closing (for himself, herself or itself and for his, her or its, successors, heirs and assigns), to the fullest extent permitted by Law and the Governing Documents of SPAC, and agrees not to assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate that the shares of Class B Common Stock held by the Sponsor convert into shares of Class A common stock, par value $0.0001 per share (the “Class A Common Stock”), of SPAC in connection with the transactions contemplated by the Business Combination Agreement. For the avoidance of doubt, the foregoing waiver does not waive the Sponsor’s rights under Section 4.03 of the SPAC Certificate of Incorporation, that provide that in no event may any Class B Common Stock convert into shares of Class A Common Stock at a ratio that is less than one-for-one.

(b) The Sponsor hereby waives any and all Redemption Rights in respect to the Required Transaction Proposals and shall not elect to cause SPAC to redeem any Subject SPAC Equity Securities beneficially owned or owned of record by the Sponsor in connection with the Required Transaction Proposals.

(c) The Sponsor hereby waives any and all right, title, interest or claim of any kind in or to any distribution of the Trust Account with respect to the Subject SPAC Equity Securities.

3. Transfer of Shares.

(a) During the Effective Period, the Sponsor hereby agrees that the Sponsor shall not, directly or indirectly, (i) sell, assign, transfer (including by operation of law), place a lien on, pledge, dispose of or otherwise encumber any of his, her or its Subject SPAC Equity Securities or otherwise agree to do any of the foregoing (each, a “Transfer”), (ii) deposit any of the Sponsor’s Subject SPAC Equity Securities into a voting trust or enter into a voting agreement or arrangement or grant any proxy or power of attorney with respect to any of the Sponsor’s Subject SPAC Equity Securities that conflicts with any of the covenants or agreements set forth in this Agreement, (iii) enter into any contract, option or other arrangement or undertaking with respect to the direct or indirect sale, assignment, transfer (including by operation of law) or other disposition of any of the Sponsor’s Subject SPAC Equity Securities, (iv) engage in any hedging or other transaction which is designed to, or which would (either alone or in connection with one or more events or developments (including the satisfaction or waiver of any conditions precedent)), result in a sale or disposition of the Sponsor’s Subject SPAC Equity Securities or (v) enter into any agreement, undertaking or take any action that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying, Sponsor’s obligations pursuant to this Agreement, except as expressly permitted by the Business Combination Agreement.

(b) From the Closing until the earlier of (i) the Lock-Up Release Date (as defined below) or (ii) the valid termination of this Agreement pursuant to Section 7, the Sponsor hereby agrees that the Sponsor shall not, directly or indirectly, Transfer any of the Founder Shares; provided, however, that the foregoing shall not apply to any Transfer (A) to SPAC’s officers or directors, any affiliates or family member of any of SPAC’s officers or directors, any members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (B) in the case of an individual, by gift to a member of one of the individual’s immediate family 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; (C) in the case of an individual, by virtue of laws of descent and distribution upon death of the individual; (D) in the case of an individual, pursuant to a qualified domestic relations order; (E) by private sales or transfers made in connection with the transactions contemplated by the Business Combination Agreement; and (F) by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; provided, that any transferee of any Transfer of the type set forth in clauses (A) through (F) must enter into a written agreement in form and substance reasonably satisfactory to the Company agreeing to be bound by this Agreement prior to the occurrence of such Transfer. Notwithstanding the foregoing, the Sponsor shall be permitted to transfer Founder Shares to the SPAC, as successor by merger to the business of the Company, or to (i) an investor in the SPAC’s private placement of equity securities consummated contemporaneous with the Closing or (ii) a stockholder of the SPAC, in each case (i) and (ii), who enters into an agreement with the SPAC not to exercise redemption rights in connection with the Closing with respect to the shares of Class A Common Stock held by such stockholder, in each case in consideration of such investor’s purchase or non-redemption. For purposes of this Agreement, the “Lock-Up Release Date” means the earliest of (A) 180 days after the date of the Closing and (B) subsequent to the Closing, (x) if the last reported sale price of the Class A Common Stock equals or exceeds $12.50 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 consecutive trading day period commencing after the Closing, or (y) the date upon completion of a liquidation, merger, stock exchange, reorganization or other similar transaction that results in all of the public stockholders of SPAC having the right to exchange their SPAC Common Stock for cash, securities or other property.

(c) In furtherance of the foregoing, SPAC hereby agrees to (i) place a revocable stop order on all Founder Shares subject to Section 3(a) and Section 3(b), including those which may be covered by a registration statement, and (ii) notify SPAC’s transfer agent in writing of such stop order and the restrictions on such Founder Shares under Section 3(a) and Section 3(b) and direct SPAC’s transfer agent not to process any attempts by the Sponsor to Transfer any Founder Shares except in compliance with Section 3(a) and Section 3(b); for the avoidance of doubt, the obligations of SPAC under this Section 3(c) shall be deemed to be satisfied by the existence of any similar stop order and restrictions currently existing on the Founder Shares.
