2. Agreement to Retain the Subject Securities.

2.1 No Transfer of Subject Securities. Until the Expiration Time, each Signing Shareholder agrees not to (a) Transfer any Subject Securities (except (i) to a permitted transferee as set forth in Section 7(c) of that certain letter agreement, dated October 27, 2025, among Purchaser and the Signing Shareholders (the “Insider Letter”) who agrees to be bound by the terms of this Agreement in a writing reasonably satisfactory to Purchaser and the Company or (ii) to any third-party investor who is a party to any non-redemption agreement with Purchaser in connection with any amendment to Purchaser’s Organizational Documents to effectuate an extension of the time Purchaser has to consummate a Business Combination and who agrees to be bound by the terms of this Agreement in a writing reasonably satisfactory to Purchaser and the Company) or (b) deposit any Subject Securities into a voting trust or enter into a voting agreement with respect to any Subject Securities or grant any proxy (except as otherwise provided herein), consent or power of attorney with respect thereto (other than pursuant to this Agreement). Until the Expiration Time, the Signing Shareholder and Purchaser agree not to amend, modify or waive any provision of the Insider Letter without the prior written consent of the Company (such consent not to be unreasonably withheld, conditioned or delayed).

2.2 Additional Purchases. Until the Expiration Time, each Signing Shareholder agrees that any Purchaser Securities that such Signing Shareholder purchases, that are issued to such Signing Shareholder by Purchaser, that are otherwise hereinafter acquired by such Signing Shareholder or with respect to which such Signing Shareholder otherwise acquires sole or shared voting power (including by proxy or power of attorney) after the execution of this Agreement and prior to the Expiration Time shall, in each case, be subject to the terms and conditions of this Agreement to the same extent as if they were Subject Securities owned by such Signing Shareholder as of the date hereof. Each of the Signing Shareholders agrees, while this Agreement is in effect, to notify Purchaser and the Company promptly in writing (including by e-mail) of the number of any additional Subject Securities acquired, or over which voting power is acquired, by such Signing Shareholder, if any, after the date hereof.

2.3 Unpermitted Transfers. Any Transfer or attempted Transfer of any Subject Securities in violation of this Section 2 shall, to the fullest extent permitted by applicable Law, be null and void ab initio.

3. Voting of Subject Shares. Hereafter until the Expiration Time, each Signing Shareholder hereby unconditionally and irrevocably agrees that, at any meeting of the stockholders of Purchaser (or any adjournment or postponement thereof), and in any action by written consent of the stockholders of Purchaser requested by the board of directors of Purchaser or otherwise undertaken as contemplated by the Transactions (which written consent shall be delivered promptly, and in any event not later than two (2) Business Days, after Purchaser requests such delivery), such Signing Shareholder shall: (a) if a meeting is held, attend and appear at the meeting, in person or by proxy, or otherwise cause its Subject Shares to be counted as present thereat for purposes of establishing a quorum, and such Signing Shareholder shall vote, or cause to be voted, all of the Subject Shares to which such Signing Shareholder has sole or shared voting power and is entitled to vote; and/or (b) if a written consent or approval is requested, duly and promptly execute and provide such written consent or approval (or cause to be voted or so consented or approved), in respect of all of its Subject Shares: (i) to approve and adopt the Business Combination Agreement and the Transactions, (ii) in any other circumstances upon which a vote, consent or other approval with respect to the Business Combination Agreement or the Transactions is sought, to vote, consent or approve (or cause to be voted, consented or approved) all of such Signing Shareholder’s Subject Shares held at such time in favor of the foregoing, and (iii) to vote against and withhold consent with respect to any merger, purchase or divestiture of all or substantially all of Purchaser’s assets or other business combination transaction (other than the Business Combination Agreement and the Transactions), and any other proposal 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 the closing conditions of Purchaser, the Company or Merger Sub under the Business Combination Agreement not being satisfied, or otherwise result in a breach of any of the representations, warranties, covenants or other obligations or agreements of Purchaser, the Company or Merger Sub, in each case, in accordance with the recommendation of the board of directors of Purchaser as set forth in the Proxy Statement delivered in connection with such meeting of Purchaser’s stockholders. No Signing Shareholder shall take or omit to take, or commit or agree to take or omit to take, any action inconsistent with the foregoing that would be effective prior to the Expiration Time.

4. Waiver of Anti-Dilution Adjustment. Subject to the satisfaction or waiver of each of the conditions to Closing set forth in Sections 7.01 and 7.03 of the Business Combination Agreement, effective immediately prior to the Closing, each Signing Shareholder hereby waives (for itself and on behalf of its successors and assigns), in accordance with Section 17.4 of Purchaser’s Amended and Restated Articles of Association as in effect as of the date hereof (the “Purchaser Charter”), any and all rights that any holder of Purchaser Class B Ordinary Shares has or will have under Section 17.3 of the Purchaser Charter to receive, with respect to each Purchaser Class B Ordinary Share, more than one (1) Purchaser Class A Ordinary Share upon the automatic conversion of Purchaser Class B Ordinary Shares in accordance with the Purchaser Charter in connection with the consummation of the Transactions. Each Signing Shareholder hereby represents and warrants that the foregoing waiver is binding on all holders of Purchaser Class B Ordinary Shares and their successors and assigns. Without limitation of the foregoing, each Signing Shareholder hereby acknowledges and agrees that pursuant to the Business Combination Agreement, upon consummation of the Transactions, the Purchaser Class B Ordinary Shares shall convert into Purchaser Class A Ordinary Shares on a one-to-one basis. For the avoidance of doubt, if either this Agreement or the Business Combination Agreement is terminated, then this Section 4 shall be deemed null and void ab initio.

5. Sponsor Share Forfeiture.

(a) Sponsor shall, immediately prior to (and contingent upon) the Closing, forfeit, or cause to be forfeited, to Purchaser the sum of (i) a number of Purchaser Class B Ordinary Shares equal to 50% of the number of new shares (if any) to be issued by the Surviving Company at the Closing as consideration or inducement payments pursuant to the terms of any non-redemption agreements or subscription agreements entered into by Purchaser in connection with the PIPE Investment or other forms of financings, plus (ii) an additional number of Purchaser Class B Ordinary Shares equal to the product of the percentage of Purchaser Class A Ordinary Shares redeemed in connection with the Transactions, multiplied by the total number of Sponsor’s remaining Purchaser Class B Ordinary Shares (after giving effect to forfeitures in the immediately preceding clause (i)) (all such forfeited shares, the “Forfeited Founder Shares” and the forfeiture of the Forfeited Founder Shares pursuant to this Section 5(a), the “Sponsor Forfeiture”); provided, however, that in no event shall the aggregate number of Forfeited Founder Shares exceed 3,150,000. For the avoidance of doubt, nothing in this Section 5 shall require Sponsor to forfeit or transfer any other securities apart from the Forfeited Founder Shares.

(b) To effect the Sponsor Forfeiture, immediately prior to (and contingent upon) the Closing: (i) Sponsor shall transfer the Forfeited Founder Shares to Purchaser for cancellation and in exchange for no consideration; (ii) Purchaser shall immediately retire and cancel all of the Forfeited Founder Shares (and shall direct Purchaser’s transfer agent (or such other intermediaries as appropriate) to take any and all such actions incidental thereto); and (iii) Sponsor and Purchaser each shall take such actions as are necessary to cause the Forfeited Founder Shares to be retired and cancelled, after which the Forfeited Founder Shares shall no longer be issued or outstanding.

(c) Prior to the Closing, Sponsor shall not, directly or indirectly, sell, transfer or otherwise dispose of or hypothecate, or otherwise grant any interest in or to, the Forfeited Founder Shares other than pursuant to the Sponsor Forfeiture. Sponsor hereby authorizes Purchaser during the period from the date hereof until the earlier of the Closing or termination of this Agreement to cause its transfer agent for the Forfeited Founder Shares to decline to transfer, and to note stop transfer restrictions on the stock register and/or legends on the stock certificate(s) or book entries relating to the Forfeited Founder Shares.

6. No Redemption. Each Signing Shareholder irrevocably and unconditionally agrees to, from the date hereof and until the Expiration Time, not elect to cause or demand Purchaser to redeem any Subject Shares now or at any time legally or beneficially owned by such Signing Shareholder, or otherwise submit, tender or surrender any of its Subject Shares for redemption, in each case in connection with an extension of Purchaser’s expiration date or the Purchaser Shareholders’ Meeting.

7.2 Further Actions. Each of the Signing Shareholders agrees, while this Agreement is in effect, not to take or omit to take, or agree to commit to take or omit to take, any action that would make any representation and warranty of such Signing Shareholder contained in this Agreement inaccurate in any material respect. Each of the Signing Shareholders further agrees that it shall take all actions reasonably necessary and cooperate with Purchaser and the Company to effect the transactions contemplated hereby and the Transactions, including to take or omit to take such actions, and execute such agreements, as may be reasonably requested by Purchaser or the Company in connection with the transactions contemplated hereby and the Transactions or that are reasonably necessary to give further effect thereto.

Accordingly, each Party shall be entitled to seek an injunction or restraining order to prevent breaches of this Agreement and to seek to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate, this being in addition to any other right or remedy to which such Party may be entitled under this Agreement, at law or in equity.
