Section 1.2 No Transfer. During the period commencing on the date hereof and ending on the earlier of (a) the Effective Time and (b) such date and time as the Merger Agreement shall be terminated in accordance with Article IX thereof (the earlier of clauses (a) and (b), the “Expiration Time”), each Sponsor shall not (i) sell, offer to sell, contract or agree to sell,

Section 1.3 New Securities. In the event that, including as a result of the Domestication, (a) any Parent Ordinary Shares, Parent Warrants, or other equity securities of Parent are issued to a Sponsor after the date of this Support Agreement pursuant to any stock dividend, stock split, recapitalization, reclassification, combination or exchange of Parent Ordinary Shares or Parent Warrants of, on or affecting the Parent Ordinary Shares or Parent Warrants owned by such Sponsor or otherwise, (b) a Sponsor purchases or otherwise acquires beneficial ownership of any Parent Ordinary Shares, Parent Warrants or other equity securities of Parent after the date of this Support Agreement, or (c) a Sponsor acquires the right to vote or share in the voting of any Parent Ordinary Shares or other equity securities of Parent after the date of this Support Agreement (such Parent Ordinary Shares, Parent Warrants or other equity securities of Parent, collectively the “New Securities”), then such New Securities acquired or purchased by such Sponsor shall be subject to the terms of this Support Agreement to the same extent as if they constituted the Parent Ordinary Shares or Parent Warrants owned by such Sponsor as of the date hereof.

Section 1.4 Support Agreements.

(a) At any meeting of the shareholders of Parent, however called, or at any adjournment or postponement thereof, or in any other circumstance in which the vote, consent or other approval of the shareholders of Parent is sought, each Sponsor shall (i) appear at each such meeting or otherwise cause all of its Parent Ordinary Shares to be counted as present thereat for purposes of calculating a quorum and (ii) vote (or cause to be voted), or execute and deliver a written consent (or cause a written consent to be executed and delivered) covering, all of its Subject Securities:

(i) in favor of the Parent Shareholder Approval Matters and in favor of any proposal in respect of an Extension Amendment;

(ii) against (or otherwise withhold written consent of, as applicable) any Business Combination or any proposal relating to a Business Combination (in each case, other than as contemplated by the Merger Agreement);

(iii) against (or otherwise withhold written consent of, as applicable) any merger agreement or merger, consolidation, combination, sale of substantial assets,

2

reorganization, recapitalization, dissolution, liquidation or winding up of or by Parent (other than the Merger Agreement and the transactions contemplated thereby);

(iv) against (or otherwise withhold written consent of, as applicable) any change in the business, management or board of directors of Parent (other than in connection with the Merger Agreement and the transactions contemplated thereby); and

(v) against (or otherwise withhold written consent of, as applicable) any proposal, action or agreement that would (A) impede, frustrate, prevent or nullify any provision of this Support Agreement or the Merger Agreement or any of the transactions contemplated hereby or thereby, (B) result in a breach in any respect of any covenant, representation, warranty or any other obligation or agreement of Parent or Merger Sub under the Merger Agreement, (C) result in any of the conditions set forth in Article VIII of the Merger Agreement not being fulfilled or (D) change in any manner the dividend policy or capitalization of, including the voting rights of any class of capital stock of, Parent.

Each Sponsor hereby agrees that it shall not commit or agree to take any action inconsistent with the foregoing, and shall not deposit any of its Parent Ordinary Shares in a voting trust, grant any proxy or power of attorney with respect to any of its Parent Ordinary Shares or subject any of its Parent Ordinary Shares to any arrangement or agreement with respect to the voting of such Parent Ordinary Shares unless specifically requested to do so by the Company and Parent in writing in connection with the Merger Agreement, the Additional Agreements or the transactions contemplated thereby.

(b) Each Sponsor shall comply with, and fully perform, all of its obligations, covenants and agreements set forth in, that certain Letter Agreement, dated as of April 6, 2022, by and among the Sponsors and Parent (the “Sponsor Letter”).

(c) Each Sponsor agrees that, if Parent seeks shareholder approval of the transactions contemplated by the Merger Agreement or any Additional Agreements, such Sponsor shall not redeem any Subject Securities owned by it in conjunction with such shareholder approval or the transactions contemplated thereby.

5

(c) No Conflicts. The execution and delivery of this Support Agreement by such Sponsor does not, and the performance by such Sponsor of his, her or its obligations hereunder will not, (i) if such Sponsor is not an individual, conflict with or result in a violation of the Organizational Documents of such Sponsor or (ii) require any consent or approval from any third party that has not been given or other action that has not been taken by any third party (including under any Contract binding upon such Sponsor or such Sponsor’s Parent Ordinary Shares or Parent Warrants), in each case, to the extent such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor of his, her or its obligations under this Support Agreement.

(d) Litigation.
