(ix) transfers in connection with the Company’s initial Business Combination with the Company’s consent to any third party;

provided, however, that in the case of clauses (i) through (v), (viii) and (ix), these permitted transferees must enter into a written agreement, in substantially the form of this Agreement, agreeing to be bound by the Lock-Up Restrictions and shall have the same rights and benefits under this Agreement. For purposes of this paragraph, “immediate family” shall mean a spouse, domestic partner, child, grandchild or other lineal descendant (including by adoption), father, mother, brother or sister of an individual; and “affiliate” shall have the meaning set forth in Rule 405 under the Securities Act of 1933, as amended.

(d) In furtherance of the foregoing, the Company, and any duly appointed transfer agent for the registration or transfer of the Locked-Up Shares, are hereby authorized to decline to make any transfer of securities if such Transfer would constitute a violation or breach of the Lock-Up Restrictions.

3. Miscellaneous.

(a) If, during the Lock-Up Periods, the Company Ordinary Shares outstanding as of immediately following the First Effective Time shall have been changed into a different number of shares or a different class by reason of any share capitalization, dividend, distribution, combination, reverse share split, share consolidation, split, subdivision, conversion, exchange, transfer, sale, cancelation, repurchase, redemption or reclassification, or any similar event shall have occurred, then the Company Per Share Trading Price specified in Section 2(a)(i)(B) shall be equitably adjusted to reflect such change.

(b) The Company shall remove, and shall cause to be removed (including by causing its transfer agent and The Depository Trust Company (as applicable) to remove), any legends, marks, stop-transfer instructions or other similar notations pertaining to the lock-up arrangements herein from the book-entries evidencing any Locked-Up Shares at the time any such share is no longer subject to the Lock-Up Restrictions (any such Locked-Up Share, a “Free Share”), and shall take all such actions (and shall cause to be taken all such actions) necessary or proper to cause the Free Shares to be consolidated under the CUSIP(s) and/or ISIN(s) applicable to the unrestricted Company Ordinary Shares or so that the Free Shares are in a like position. Any holder of a Locked-Up Share is an express third-party beneficiary of this Section 3(b) and entitled to enforce specifically the obligations of the Company set forth in this Section 3(b) directly against the Company.

(c) This Agreement shall be effective the date hereof and shall immediately terminate upon the earlier of (x) the termination of the Business Combination Agreement pursuant to its terms, and (y) the date on which none of the Company, Sponsor or any holder of a Locked-Up Share has any rights or obligations hereunder.

(d) Each of Sponsor and the Company hereby represents and warrants that it has full power and authority to enter into this Agreement and that this Agreement constitutes its legal, valid and binding obligation, enforceable against it in accordance with its terms. Upon the other party’s request, Sponsor or the Company, as applicable, will execute any additional documents necessary in connection with enforcement hereof.

(e) This Agreement constitutes the entire agreement and understanding between the parties hereto relating to the subject matter hereof and the transactions contemplated hereby and supersedes any other agreements and understandings, whether written or oral, that may have been made or entered into by or between the parties hereto relating to the subject matter hereof or the transactions contemplated hereby. This Agreement may not be changed, amended, modified or waived (other than to correct a typographical error) as to any particular provision, except by a written instrument executed by all parties hereto.

(f) No party hereto shall assign this Agreement or any part hereof without the prior written consent of the other party hereto; provided, that no such assignment shall relieve the assigning party of its obligations hereunder. Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns. Any attempted assignment in violation of the terms of this paragraph shall be null and void, ab initio. For the avoidance of doubt, no transfer of Company Ordinary Shares, Locked-Up Shares or Free Shares shall be (or be deemed to be) an assignment of this Agreement or the rights or obligations hereunder.

(g) This Agreement shall be governed by, and construed in accordance with, the internal substantive laws of the State of New York applicable to contracts entered into and to be performed solely within such state, without giving effect to principles or rules of conflict of laws to the extent such principles or rules would require or permit the application of laws of another jurisdiction. Any dispute, controversy, difference, or claim arising out of or relating to this Agreement, including its existence, validity, interpretation, performance, breach, or termination, or any dispute regarding non-contractual obligations arising out of or relating to this Agreement, shall be referred to and finally resolved by arbitration administered by the Singapore International Arbitration Centre under the Arbitration Rules of the Singapore International Arbitration Centre in force when the Notice of Arbitration is submitted. The seat of arbitration shall be Singapore. There shall be three arbitrators. The arbitration proceedings shall be conducted in English. The law of the arbitration proceedings shall be Singapore law. For the avoidance of doubt, a request by a party hereto to a court of competent jurisdiction for interim measures necessary to preserve such party’s rights, including pre- arbitration attachments, injunctions, or other equitable relief, shall not be deemed incompatible with, or a waiver of, the agreement to arbitrate in this Section.

(h) Each of the parties hereto acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event of a breach of this Agreement by it, money damages will be inadequate and the other party will have no adequate remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by it in accordance with their specific terms or were otherwise breached. Accordingly, the non- breaching party shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by the other party and 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 the non-breaching party may be entitled under this Agreement, at law or in equity.

(i) This Agreement may be executed in two or more counterparts (any of which may be delivered by electronic transmission), each of which shall constitute an original, and all of which taken together shall constitute one and the same instrument.
