Any Transfer in violation of this Section 3(a) with respect to the Subject Shares of a Holder shall be void ab initio and of no force or effect.

(b) Changes to Company Shares. In the event that, during the Voting Period, (i) any Company Shares are issued to a Holder after the date of this Agreement pursuant to any equity distribution, or any change in the equity interests of the Company by reason of any equity distribution, equity split, recapitalization, consolidation, conversion, exchange of equity interests or the like, (ii) such Holder purchases or otherwise acquires beneficial ownership of any Company Shares or (iii) such Holder acquires the right to vote or share in the voting of any Company Shares (collectively the “New Shares”), then such New Shares acquired or purchased by such Holder shall be subject to the terms of this Agreement to the same extent as if they constituted the Company Shares and Subject Shares owned by the Holder as of the date hereof. Each Holder agrees during the Voting Period to notify the SPAC and the Company promptly in writing of the number and type of any changes to Holder’s ownership of or voting rights with respect to the Subject Shares, upon Holder’s acquisition or commitment to acquire any additional Company Shares or upon any other changes involving Holder relating to the equity interests or securities convertible or exercisable for equity interests of the Company, in each case, except for in respect of any transaction that is expressly contemplated under the Business Combination Agreement or any Ancillary Agreement.

(i) Amendments and Waivers. Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively) only with the written consent of each of the parties hereto. No failure or delay by a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term, condition, or provision.

(j) Severability. If any term, provision, covenant, or restriction of this Agreement shall be held invalid, void or unenforceable in a jurisdiction by a court of competent jurisdiction or other authority, such provision shall be modified or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity, legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity, legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties will substitute for any invalid, illegal or unenforceable provision a suitable and equitable provision that carries out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid, illegal or unenforceable provision.

10

(k) Specific Performance. The parties hereto hereby acknowledge and agree that irreparable injury for which monetary damages (even if available) would not be an adequate remedy would occur if any parties hereto does not perform any provision of this Agreement in accordance with its specified terms or otherwise breaches such provisions. Accordingly, the parties hereto acknowledge and agree that, prior to a valid termination, to prevent breaches or threatened breaches by the parties hereto of any of their respective covenants or obligations set forth in this Agreement, including its failure to take all actions required under the express terms of this Agreement to consummate the transactions contemplated hereby, and that prior to a valid termination of this Agreement, the parties hereto shall be entitled to specific performance of such agreements and covenants in such event and other equitable relief to prevent breaches or threatened breaches of this Agreement, in addition to any other remedy to which they are entitled at law or in equity. Each of the parties hereto agrees that it will not oppose the granting of any such injunction, specific performance and other equitable relief on the basis that any other party hereto has an adequate remedy at Law or that any award of specific performance is not an appropriate remedy for any reason at Law or in equity. Each party hereto hereby waives any requirement to provide any bond or other security in connection with such order or injunction.

(l) Expenses. Each party shall be responsible for its own fees and expenses (including the fees and expenses of investment bankers, accountants and counsel) in connection with the entering into of this Agreement, the performance of its obligations hereunder and the consummation of the transactions contemplated hereby.

(m) No Partnership, Agency or Joint Venture. This Agreement is intended to create a contractual relationship among the Holders, Company, SPAC, and Holdco, and is not intended to create, and does not create, any agency, partnership, joint venture or any like relationship among the parties hereto or among any other holders of Company Shares entering into voting agreements with the Company or the SPAC. No Holder is affiliated with any other holder of Company Shares entering into a voting or support agreement with the Company or the SPAC in connection with the Business Combination Agreement and Holder has acted independently regarding its decision to enter into this Agreement. Nothing contained in this Agreement shall be deemed to vest in the Company or the SPAC any direct or indirect ownership or incidence of ownership of or with respect to any Company Shares.

(n) Further Assurances. From time to time, at another party’s request and without further consideration, each party shall execute and deliver such additional documents and take all such further action as may be reasonably necessary or desirable to consummate the transactions contemplated by this Agreement.

(o) Entire Agreement. This Agreement (together with the agreements referenced herein) constitutes the entire agreement among the parties hereto with respect to the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is expressly canceled; provided, that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations of the parties under the Business Combination Agreement or any Ancillary Agreement. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies of the SPAC or any of the obligations of any Holder under any other agreement between such Holder and the SPAC or any certificate or instrument executed by such Holder in favor of the SPAC, and nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of the SPAC or any of the obligations of such Holder under this Agreement.

(p) Counterparts. This Agreement may be executed and delivered (including by electronic signature or by email in portable document format) in two or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.
