WHEREAS, as a condition and inducement to the willingness of SPAC, PubCo and the Company to enter into the Business Combination Agreement, PubCo, SPAC, the Company and the Sponsor are entering into this Agreement.
 
NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements herein contained, and intending to be legally bound hereby, PubCo, SPAC, the Company and the Sponsor hereby agree as follows:
 
1.          Agreement to Vote. Subject to the earlier termination of this Agreement in accordance with Section 9, Sponsor, in its capacity as a shareholder of SPAC, irrevocably and unconditionally agrees that at a meeting of SPAC’s shareholders to be convened for the purpose of obtaining the requisite SPAC Shareholders Approval in connection with the Transactions or any other meeting of SPAC’s shareholders with respect to the Transactions (whether annual or extraordinary and whether or not an adjourned or postponed meeting, however called and including any adjournment or postponement thereof), such Sponsor shall:
 
(a)          if and when such meeting is held, appear at such meeting in person or by proxy or otherwise cause the Covered Securities, which are entitled to vote, to be counted as present thereat for the purpose of establishing a quorum;
 
(b)          vote, or cause to be voted, at such meeting (or execute and deliver a written consent, if applicable, causing to be voted) all of the Covered Securities, which are entitled to vote, owned as of the record date for such meeting in favor of the SPAC Shareholders Approval and any other matters necessary or reasonably requested by SPAC for consummation of the Transactions, including any actions necessary to effectuate the matters contemplated by the SPAC Shareholders Approval;
 
(c)          vote, or cause to be voted, at such meeting (or execute and deliver a written consent, if applicable, causing to be voted) all of the Covered Securities, which are entitled to vote, owned as of the record date for such meeting against any change in the business, management or board of directors of SPAC;
 
(d)          vote, or cause to be voted, at such meeting (or execute and deliver a written consent, if applicable, causing to be voted) all of such Covered Securities, which are entitled to vote, owned as of the record date for such meeting against a SPAC Acquisition Proposal or any other transaction involving SPAC that would be reasonably likely to, in any material respect, impede, interfere with, delay or attempt to discourage, frustrate the purposes of, result in a breach by SPAC of, prevent or nullify any provision of the Business Combination Agreement or any other Transaction Document, the Initial Merger, or any other Transaction, or change in any manner the voting rights of any class of SPAC’s share capital; and
 
(e)          in any other circumstances upon which a consent or other approval is required under SPAC’s Organizational Documents or otherwise sought in furtherance of the Transactions, vote, consent or approve (or cause to be voted, consented or approved) all of the Covered Securities owned at such time, which are entitled to vote, in favor thereof.
 
The obligations of the Sponsor specified in this Section 1 shall apply whether or not the Mergers or any action described above is recommended by the board of directors of SPAC or any committee thereof or the board of directors of SPAC or any committee thereof has previously recommended the Mergers or such action but changed its recommendation.
 
2.          Surrendered Sponsor Shares. Sponsor hereby acknowledges and agrees that, immediately preceding the Sponsor Share Conversion (and for the avoidance of doubt, on the Business Day prior to the Closing Date and prior to the Initial Merger), it shall automatically surrender for no consideration 3,018,750 SPAC Class B Ordinary Shares and that from and after such time such surrendered shares shall be deemed to be cancelled and no longer outstanding on the books of SPAC and no Person shall have any further right with respect thereto.
 
3.          Sponsor Earn Out.
 
(a)          Sponsor agrees that, immediately following the Sponsor Share Conversion and the Initial Merger Effective Time but prior to the Second Merger Effective Time, (x) an aggregate of 3,450,000 PubCo Ordinary Shares held by Sponsor shall be registered in the name of the Sponsor and shall be duly authorized, validly issued, fully paid and non-assessable, and free and clear of all Liens and (y) an aggregate of 2,156,250 PubCo Ordinary Shares registered in the name of the Sponsor (the securities in clause (y), the “Sponsor Earn-Out Shares”) shall have the Legend affixed to them and be held subject to the terms and conditions of this Section 3 but shall, in all other respects be duly authorized, validly issued, fully paid and non-assessable, and free and clear of all Liens.
 
2
(b)          Legends. During the Earnout Lock-Up Period, each certificate or book entry position statement evidencing Sponsor Earn-Out Shares shall be stamped or otherwise imprinted with a legend (the “Legend”) in substantially the following form, in addition to any other applicable legends:
 
“THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO RESTRICTIONS ON TRANSFER, AND CERTAIN OTHER AGREEMENTS, SET FORTH IN THE SPONSOR SUPPORT AGREEMENT, DATED AS OF JANUARY 17, 2023, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”) AND CERTAIN OTHER PARTIES NAMED THEREIN. A COPY OF SUCH SPONSOR SUPPORT AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”
 
(c)          Procedures Applicable to the Sponsor Earn-Out Shares.
 
(i)           As soon as practicable, and in any event within five (5) Business Days after the occurrence of a Triggering Event (as defined below), PubCo shall remove, or cause to be removed, the Legend from the books and records of PubCo evidencing the Sponsor Earn-Out Shares with respect to which a Triggering Event has occurred and such shares shall no longer be subject to any of the terms of this Section 3 (any such removal of the Legend and other restrictions, a “Release”).
 
(ii)          Sponsor shall not Transfer any Sponsor Earn-Out Shares until the date on which the relevant vesting triggers have been satisfied as described in Section 3(d) below, provided however, that the Sponsor may Transfer Sponsor Earn-Out Shares to any direct or indirect beneficial owner of Sponsor or any Affiliate thereof, provided, further, that any such permitted transferee must enter into a written agreement agreeing to be bound by the provisions of this Agreement.
 
(iii)          Any Sponsor Earn-Out Shares not eligible to be Released in accordance with the terms of Section 3(d) or Section 3(f) on or before the fifth (5th) anniversary of the Closing Date (the period commencing on the Closing Date and ending on such date, the “Earnout Lock-Up Period”) shall be automatically surrendered for no consideration to PubCo upon the expiration of such Earnout Lock-Up Period and canceled (such shares, “Forfeited Shares”) and Sponsor shall not have any rights with respect thereto.
 
(d)          Release of Sponsor Earn-Out Shares. The Sponsor Earn-Out Shares shall be Released as follows (each, a “Triggering Event”):
 
(i)          If, at any time during the Earnout Lock-Up Period, the VWAP of PubCo Ordinary Shares is equal to or greater than $12.50 for any 20 Trading Days within any period of 30 consecutive Trading Days (the date when the foregoing is first satisfied, the “First Triggering Event Date”), one-half (1/2) of the Sponsor Earn-Out Shares (the “First Earn-Out Shares”) shall be Released and no longer be subject to surrender conditions provided in this Section 3  as of the First Triggering Event Date.
 
(ii)          If, at any time during the Earnout Lock-Up Period, the VWAP of PubCo Ordinary Shares is equal to or greater than $15.00 for any 20 Trading Days within any period of 30 consecutive Trading Days (the date when the foregoing is first satisfied, the “Second Triggering Event Date”), one-half (1/2) of the Sponsor Earn-Out Shares shall be Released and no longer be subject to the surrender conditions provided in this Section 3 as of the Second Triggering Event Date.
 
3
(e)          If the Second Triggering Event Date occurs at a time when the First Earn-Out Shares have not been Released, then all of the Sponsor Earn-Out Shares shall immediately be Released and no longer be subject to the surrender conditions provided in this Section 3 as of the Second Triggering Event Date.
 
(f)          In the event that there is a PubCo Change of Control during the Earnout Lock-Up Period, any Sponsor Earn-Out Shares that have not previously been Released pursuant to a Triggering Event shall be deemed to have been Released immediately prior to the closing of such PubCo Change of Control, and the holder of any Sponsor Earn-Out Shares shall be eligible to participate in such PubCo Change of Control with respect to such Sponsor Earn-Out Shares on the same terms, and subject to the same conditions, as apply to the holders of PubCo Ordinary Shares generally. Upon the consummation of a PubCo Change of Control, the Earnout Lock-Up Period shall terminate.
 
(g)          The PubCo Ordinary Share price targets set forth in Section 3(d) shall be equitably adjusted for stock splits, reverse stock splits, stock dividends, reorganizations, recapitalizations, reclassifications, combination, exchange of shares or other like change or transaction with respect to PubCo Ordinary Shares occurring on or after the Closing. For the avoidance of doubt, prior to the expiration of the Earnout Lock-Up Period, Sponsor shall be entitled to vote and receive dividends with respect to its Sponsor Earn-Out Shares until such shares are deemed Forfeited Shares.

Sponsor hereby irrevocably but conditioned upon the consummation of the Mergers and the filing of the PubCo Articles, (i) agrees that pursuant to Section 2.01(b) of the Business Combination Agreement, on the Business Day prior to the Closing Date and prior to the Initial Merger, each issued and outstanding SPAC Class B Ordinary Share, after giving effect to the surrender of SPAC Class B Ordinary Shares pursuant to Section 2 herein, shall be converted automatically into one (1) SPAC Class A Ordinary Share (the “Sponsor Share Conversion”), and (ii) waives any adjustment to the Sponsor Share Conversion pursuant to the Initial Conversion Ratio (as such term is defined in the SPAC Articles) to which it would otherwise be entitled pursuant to Article 17 (Class B Ordinary Share Conversion) of the SPAC Articles and any other anti-dilution rights or protections with respect to the Sponsor Share Conversion resulting from the Transactions.
 
5.          No Redemption. Sponsor agrees that, from the date hereof and until the termination of this Agreement, Sponsor shall not elect to cause SPAC to redeem any Covered Securities, or submit or surrender any of the Covered Securities for redemption (save for the surrender of SPAC Class B Ordinary Shares pursuant to Section 2), in connection with the Transactions.
 
6.          Consent to Disclosure. Sponsor hereby consents to the publication and disclosure in the Joint Proxy Statement/Prospectus (and, as and to the extent otherwise required by applicable securities Laws or the SEC or any other securities authorities, any other documents or communications provided by SPAC, the Company or PubCo to any Governmental Authority or to security holders of SPAC) of the Sponsor’s identity and beneficial ownership of Sponsor Shares and Sponsor Warrants and the nature of the Sponsor’s commitments, arrangements and understandings under and relating to this Agreement and, if deemed appropriate by SPAC, the Company or PubCo, a copy of this Agreement.

Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under Laws, 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.
 
26.          Counterparts. This Agreement and any amendment hereto may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement or any amendment hereto by electronic means, including docusign, e-mail, or scanned pages shall be effective as delivery of a manually executed counterpart to this Agreement or any amendment hereto.
 
27.          Interpretation and Construction. The words “hereof,” “herein” and “hereunder” and words of like import used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. References to Sections are to Sections of this Agreement unless otherwise specified. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular. The definitions contained in this Agreement are applicable to the masculine as well as to the feminine and neuter genders of such term. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing and other means of reproducing words (including electronic media) in a visible form. References to any statute shall be deemed to refer to such statute and to any rules or regulations promulgated thereunder. References to any person include the successors and permitted assigns of that person. References from or through any date mean, unless otherwise specified, from and including such date or through and including such date, respectively.

SCHEDULE A

Defined Terms

“PubCo Change of Control” means any transaction or series of related transactions (a) under which PubCo, directly or indirectly, acquires or otherwise purchases (i) another Person or any of its Affiliates or (ii) all or a material portion of the assets, business or equity securities of another Person or (b) under which any Person(s) makes any equity or similar investment in PubCo, in each case, that results, directly or indirectly, in the shareholders of PubCo, as of immediately prior to such transaction holding, in the aggregate, less than 50% of the voting shares of PubCo (or any successor or parent company of PubCo) immediately after the consummation thereof (whether by merger, consolidation, tender offer, recapitalization, purchase or issuance of equity securities, tender offer or otherwise).
 
“Trading Day” means any day on which PubCo Ordinary Shares are actually traded on the principal securities exchange or securities market on which such PubCo Ordinary Shares are then traded.
 
“VWAP” means, for any security as of any date(s), the volume-weighted average price for such security on the principal securities exchange or securities market on which such security is then traded during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg through its “HP” function (set to weighted average) or, if the foregoing does not apply, the volume-weighted average price of such security in the over-the-counter market on the electronic bulletin board for such security during the period beginning at 9:30:01 a.m., New York time, and ending at 4:00:00 p.m., New York time, as reported by Bloomberg, or, if no volume-weighted average price is reported for such security by Bloomberg for such hours, the average of the highest closing bid price and the lowest closing ask price of any of the market makers for such security as reported by OTC Markets Group Inc. If the VWAP cannot be calculated for such security on such date(s) on any of the foregoing bases, the VWAP of such security on such date(s) shall be the fair market value as determined reasonably and in good faith by a majority of the disinterested independent directors of the board of directors (or equivalent governing body) of the applicable issuer. All such determinations shall be appropriately adjusted for any stock dividend, stock split, stock combination, recapitalization or other similar transaction during such period.
