REPRESENTATIONS AND WARRANTIES

Section 2.1Representations and Warranties of the Sponsor Parties. Each Sponsor Party represents and warrants as of the date hereof to the Company (severally and not jointly and solely with respect to itself, himself or herself and not with respect to any other Sponsor Party) as follows:

If such Sponsor Party is an individual, such Sponsor Party has full legal capacity, right and authority to execute and deliver this Agreement, to perform his or her obligations hereunder and to consummate the transactions contemplated hereby. This Agreement has been duly and validly executed and delivered by such Sponsor Party and assuming that this Agreement constitutes the legal, valid and binding obligation of each other party hereto, this Agreement constitutes a legal, valid and binding obligation of such Sponsor Party, and is enforceable against such Sponsor Party in accordance with the terms hereof, subject to the Bankruptcy and Equity Exception.

(b)Ownership. As of the date hereof, such Sponsor Party is the record and beneficial owner (as defined in the Securities Act) of, and has good title to, all of such Sponsor Party’s Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units and Acquiror Cayman Warrants as set forth opposite such Sponsor Party’s name on Schedule I attached hereto, and there exist no Liens or any other limitation or restriction (including any restriction on the right to vote, sell or otherwise dispose of such Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units or Acquiror Cayman Warrants (other than transfer restrictions under the Securities Act)) affecting any such Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units or Acquiror Cayman Warrants, other than Liens pursuant to (i) this Agreement, (ii) the Acquiror’s Organizational Documents, (iii) the Transaction Agreement, (iv) the Insider Letter or (v) any applicable securities Laws. Such Sponsor Party’s Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units and Acquiror Cayman Warrants as set forth opposite such Sponsor Party’s name on Schedule I attached hereto are the only equity securities in Acquiror owned of record or beneficially by such Sponsor Party on the date of this Agreement, and none of such Sponsor Party’s Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units or Acquiror Cayman Warrants are subject to any proxy, voting trust or other agreement or arrangement with respect to the voting of such Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units or Acquiror Cayman Warrants, except as provided hereunder and under the Insider Letter. Other than the Acquiror Cayman Warrants and the right of Sponsor or its Affiliates to convert Indebtedness pursuant to a Sponsor Loan into Acquiror Cayman Warrants, such Sponsor Party does not hold or own any rights to acquire (directly or indirectly) any equity securities of Acquiror or any equity securities convertible into, or which can be exchanged for, equity securities of Acquiror.

5

(c)No Conflicts. The execution and delivery of this Agreement by such Sponsor Party do not, and the consummation of the transactions contemplated hereby and the performance by such Sponsor Party of his, her or its obligations hereunder will not, (i) if such Sponsor Party is not an individual, conflict with or result in a violation of the Organizational Documents of such Sponsor Party or if such Sponsor Party is an individual, conflict with the rights of such Sponsor Party’s spouse or domestic partner, as applicable, or (ii) require any consent or approval that has not been given or other action that has not been taken by any Person (including under any Contract binding upon such Sponsor Party or such Sponsor Party’s Acquiror Cayman Class A Ordinary Shares, Acquiror Cayman Class B Ordinary Shares, Acquiror Cayman Units or Acquiror Cayman Warrants), in each case, to the extent the absence of such consent, approval or other action would prevent, enjoin or materially delay the performance by such Sponsor Party of its, his or her obligations under this Agreement.

(d)Litigation. There are no Actions pending, or to the knowledge of such Sponsor Party, threatened against such Sponsor Party, which in any manner challenges or seeks to prevent, enjoin or materially delay the performance by such Sponsor Party of its, his or her obligations under this Agreement.

(e)Brokerage Fees. Except as set forth in Section 4.20 of the Acquiror Disclosure Letter, no broker, finder, investment banker or similar intermediary is entitled to any broker’s, finder’s or similar fee or other commission or compensation in connection with the Transactions based on any arrangement made by such Sponsor Party, for which Acquiror or any of its Affiliates may become liable.

(f) Affiliate Arrangements. Except as set forth on Section 4.21 of the Acquiror Disclosure Letter, and other than the private placement of securities in connection with Acquiror’s initial public offering, such Sponsor Party is not a party to any Sponsor Related Party Transactions.

(g)Acknowledgment. Each Sponsor Party understands and acknowledges that the Company is entering into the Transaction Agreement in reliance upon such Sponsor Party’s execution and delivery of this Agreement.
