Of the Holdings Ordinary Shares to be issued as Company Merger Consideration at the Closing, the Company Shareholders shall deposit the Escrowed Shares with the Escrow Agent and such Escrowed Shares shall become subject to forfeiture by the Company Shareholders following the Closing as set forth in this Section 2.08(c).

(i) At or prior to the Closing, the Parties and an agent mutually acceptable to SPAC and the Company, as escrow agent (the “Escrow Agent”), shall enter into an Escrow Agreement, effective as of the Closing, in form and substance reasonably satisfactory to the SPAC and the Company (the “Escrow Agreement”), pursuant to which the Company Shareholders shall deposit the Escrowed Shares with the Escrow Agent, to be held in a segregated escrow account (the “Escrow Account”). The Company Shareholders shall be shown as registered owners of their respective Escrowed Shares on the books and records of Holdings and shall be entitled to exercise voting rights with respect to such Escrowed Shares, and any dividends, distributions and other earnings on the Escrowed Shares while in the Escrow Account shall be paid directly to the Company Shareholders.

(ii) On the date that the Company’s audited financial statements for fiscal year 2025 are filed with the SEC, (A) if the Company Adjusted EBITDA for fiscal year 2025 is less than the Company 2025 FY EBITDA Target, all Escrowed Shares shall be forfeited by the Company Shareholders and surrendered to Holdings for no consideration pursuant to the Cayman Act and the Organizational Documents of Holdings and cancelled, and (B) if the Company Adjusted EBITDA for fiscal year 2025 is equal to or greater than Company 2025 FY EBITDA Target, then all of the Escrowed Shares shall be released proportionately to the Company Shareholders (the “Escrow Share Release”).

Each Party will use their commercially reasonable efforts to make their respective presentations as promptly as practicable following submission to the Independent Expert of the disputed items, and each such Party will be entitled, as part of its presentation, to respond to the presentation of the other Party and any questions and requests of the Independent Expert. In deciding any matter, the Independent Expert will be bound by the provisions of this Agreement. It is the intent of the Parties that the activities of the Independent Expert are not (and should not be considered to be or treated as) an arbitration proceeding or similar arbitral process and that no formal arbitration rules should be followed (including rules with respect to procedures and discovery). Each Party will request that the Independent Expert’s determination be made within thirty (30) days after its engagement, or as soon thereafter as possible, will be set forth in a written statement delivered to the Parties and will be final, conclusive, non-appealable and binding for all purposes hereunder (other than for fraud or manifest error).

(g) Section 8.03(j) of the Original Agreement is hereby deleted in its entirety.

(h) Section 9.01(b) of the Original Agreement is hereby amended by deleting it in its entirety and replacing it with the following:

(b) by written notice by SPAC or the Company if any of the conditions to the Closing set forth in ARTICLE VIII have not been satisfied or waived by May 2, 2025 (the “Outside Date”); provided, however, the right to terminate this Agreement under this Section 9.01(b) shall not be available to a Party if the breach or violation by such Party or its Affiliates of any representation, warranty, covenant or obligation under this Agreement was the primary cause of, or primarily resulted in, the failure of the Closing to occur on or before the Outside Date;

2. Miscellaneous. Except as expressly provided in this Amendment, all of the terms and provisions in the Original Agreement are and shall remain unchanged and in full force and effect, on the terms and subject to the conditions set forth therein. This Amendment does not constitute, directly or by implication, an amendment or waiver of any provision of the Original Agreement, or any other right, remedy, power or privilege of any party, except as expressly set forth herein. Any reference to the Merger Agreement in the Merger Agreement or any other agreement, document, instrument or certificate entered into or issued in connection therewith shall hereinafter mean the Original Agreement, as amended by this Amendment (or as the Merger Agreement may be further amended or modified after the date hereof in accordance with the terms thereof). The Original Agreement, as amended by this Amendment, together with the documents or instruments attached hereto or thereto or referenced herein or therein, constitutes the entire agreement between the parties with respect to the subject matter of the Merger Agreement, and supersedes all prior agreements and understandings, both oral and written, between the Parties with respect to its subject matter. If any provision of the Original Agreement is materially different from or inconsistent with any provision of this Amendment, the provision of this Amendment shall control, and the provision of the Original Agreement shall, to the extent of such difference or inconsistency, be disregarded. This Amendment shall be interpreted, construed, governed and enforced in a manner consistent with the Original Agreement, and, without limiting the foregoing, Sections 10.01 through 10.09 and Sections 10.11 through 10.16 of the Original Agreement are hereby incorporated herein by reference as if fully set forth herein, and such provisions apply to this Amendment as if all references to the “Agreement” contained therein were instead references to this Amendment.
