      entity, if applicable) in each jurisdiction in which its ownership of property or the character of its activities is such as to require it to be so licensed or qualified or in good standing (to the extent such concept is applicable in Sponsor’s
      jurisdiction of formation), as applicable, except where the failure to be so licensed or qualified or in good standing would not have a material adverse effect on the ability of Sponsor to enter into and perform its obligations under this Agreement
      and to consummate the transactions contemplated hereby.

    

    

    (b)  Authority.  Sponsor has all requisite
      corporate power and authority to enter into, execute, deliver and perform its obligations under this Agreement and to consummate the transactions contemplated hereunder; and all corporate actions on the part of Sponsor necessary for the

      affecting enforcement of creditors’ rights generally, and (ii) as limited by applicable Laws relating to the availability of specific performance, injunctive relief, or other equitable remedies. No consent of, or registration, declaration or filing
      with, any Governmental Authority is required to be obtained or made by Sponsor in connection with the execution, delivery and performance by Sponsor of this Agreement or the consummation by Sponsor of the transactions contemplated hereby.

      transactions contemplated hereby, in each case on the part of Sponsor, have been duly obtained or completed (as applicable) and are in full force and effect.  The execution, delivery and performance of this Agreement by Sponsor does not, and the
      consummation by Sponsor of the transactions contemplated hereby will not result in any violation of, be in conflict with, or constitute a default under, require any consent under, or give any Person rights of termination, amendment, acceleration
      (including acceleration of any obligation of Sponsor) or cancellation under, (x) (i) any Governmental Order, (ii) any provision of the Organizational Documents of Sponsor, (iii) any applicable Law, (iv) any Contract to which Sponsor is a party or by
      which its assets are bound, or (y) result in the creation of any lien or encumbrance upon any of the properties or assets of Sponsor other than liens or encumbrances pursuant to the SPAC Charter, this Agreement or any other Transaction Document or
      applicable securities laws, except in the case of sub-clauses (i), (iii), and (iv) of clause (x), as has not had, and would not reasonably be expected to have, individually or in the aggregate, a material adverse effect on the ability of Sponsor to
      enter into and perform this Agreement and to consummate the transactions contemplated hereby.

    

    

    (d)  SPAC Securities.  Sponsor is the sole
      legal and beneficial owner of the SPAC Securities set forth opposite Sponsor’s name on Schedule A hereto, and all such SPAC Securities are owned by Sponsor
      free and clear of all liens or encumbrances, other than liens or encumbrances pursuant to the SPAC Charter, this Agreement or any other Transaction Document or applicable securities laws.  Sponsor does not own legally or beneficially any shares or
      warrants of SPAC other than the SPAC Securities set forth opposite Sponsor’s name on Schedule A hereto.  Sponsor has the sole right to vote the Subject

    (f)  Adequate Information.  Sponsor is a
      sophisticated shareholder and has adequate information concerning the business and financial condition of SPAC, PubCo and the Company to make an informed decision regarding this Agreement and the transactions contemplated by the Business Combination
      Agreement and has independently and without reliance upon SPAC, PubCo or the Company and based on such information as Sponsor has deemed appropriate, made its own analysis and decision to enter into this Agreement. Sponsor acknowledges that SPAC,
      PubCo and the Company have not made and do not make any representation or warranty, whether express or implied, of any kind or character except as expressly set forth in this Agreement. Sponsor acknowledges that the agreements contained herein with
      respect to the Subject Shares held by Sponsor are irrevocable.

    

    

    (g)  Restricted Securities. Sponsor
      understands that the Shareholder Merger Consideration that Sponsor may receive in connection with its Subject Shares, the Initial Merger, the Sponsor Subscription Agreement, the Backstop Agreement and the Sponsor Forward Purchase Agreement will be
      “restricted securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, Sponsor must hold such Shareholder Merger Consideration indefinitely unless (i) they are registered with the SEC and qualified by state
      authorities, or (ii) an exemption from such registration and qualification requirements is available, and that any certificates or book entries representing the PubCo Ordinary Shares shall contain a legend to such effect.

    (4)  Irrevocable Proxy.  Sponsor hereby
      irrevocably grants to, and appoints, the Company and any individual designated in writing by the Company, and each of them individually, as Sponsor’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead
      of Sponsor, to vote the Subject Shares, or grant a written consent or approval in respect of the Subject Shares in a manner consistent with this Section 5(a).

      arrangement) with respect to the Transfer of, any Subject Shares to any person other than pursuant to the Initial Merger, (ii) grant any proxies (other than as set forth in this Agreement) or enter into any voting arrangement, whether by proxy,
      voting agreement, voting trust, voting deed or otherwise (including pursuant to any loan of Subject Shares), or enter into any other agreement, with respect to any Subject Shares, (iii) take any action that would make any representation or warranty
      of Sponsor herein untrue or incorrect, or have the effect of preventing or disabling Sponsor from performing its obligations hereunder, or (iv) commit or agree to take any of the foregoing actions or take any other action or enter into any Contract
      that would reasonably be expected to make any of its representations or warranties contained herein untrue or incorrect or would have the effect of preventing or delaying Sponsor from performing any of its obligations hereunder.  Any action attempted
      to be taken in violation of the preceding sentence will be null and void.  Sponsor hereby authorizes and requests SPAC or the Company to notify SPAC’s transfer agent that there is a stop transfer order with respect to all of the Subject Shares (and
      that this Agreement places limits on the voting of the Subject Shares). Sponsor agrees with, and covenants to, SPAC, PubCo and the Company that Sponsor shall not request that SPAC register the Transfer (by book-entry or otherwise) of any certificated
