WHEREAS, in connection with the Transactions, Sponsor has agreed to grant to the Company certain rights to purchase certain securities held by Sponsor following the Closing (the “Call Option”), on the terms and subject to the conditions set forth herein; and

WHEREAS, as a condition to their willingness to enter into the Business Combination Agreement, SPAC (and, following the Domestication, PubCo) and the Company have requested that Sponsor enter into this Agreement.

NOW, THEREFORE, in consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and the representations, warranties, covenants and agreements contained in this Agreement and the Business Combination Agreement, and intending to be legally bound hereby, the parties hereto agree as follows:

Article I.

****Representations and Warranties of Sponsor

Sponsor hereby represents and warrants to the Company and SPAC as follows:

1.1 Organization and Standing. Sponsor has been duly formed and is validly existing and in good standing under the Laws of the British Virgin Islands and has all requisite corporate power and authority to own, lease and operate its properties and to carry on its business as now being conducted. Sponsor is duly qualified or authorized to do business and is in good standing in each jurisdiction in which the character of the property owned, leased or operated by it or the nature of the business conducted by it makes such qualification or authorization necessary, except where the failure to be so qualified, authorized or in good standing would not reasonably be expected to materially impair Sponsor’s ability to perform its obligations under this Agreement.

1.2 Authorization; Binding Agreement. Sponsor has all requisite corporate power and authority to execute and deliver this Agreement, to perform its obligations hereunder and to consummate the transactions contemplated hereby. The execution and delivery of this Agreement and the consummation of the transactions contemplated hereby have been duly and validly authorized by all necessary corporate action on the part of Sponsor, and no other proceedings on the part of Sponsor are necessary to authorize the execution and delivery of this Agreement or to consummate the transactions contemplated hereby. This Agreement has been duly and validly executed and delivered by Sponsor and, assuming the due authorization, execution and delivery of this Agreement by the other parties hereto, constitutes a valid and binding obligation of Sponsor, enforceable against Sponsor in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other applicable Laws now or hereafter in effect affecting creditors’ rights generally and (b) as limited by applicable Laws relating to the availability of specific performance, injunctive relief or other equitable remedies.

1.3 Governmental Approvals. No Order of any Authority on the part of Sponsor is required to be obtained or made in connection with the execution, delivery or performance by Sponsor of this Agreement or the consummation by Sponsor of the transactions contemplated hereby, other than (a) applicable requirements, if any, of the Securities Act, the Exchange Act, and/or any state “blue sky” securities Laws, and the rules and regulations thereunder and (b) where the failure to obtain or make such Order or to make such filings or notifications has not had, and would not reasonably be expected to have, individually or in the aggregate, an adverse effect on the ability of Sponsor to enter into and perform this Agreement and to consummate the transactions contemplated hereby.

1.4 Non-Contravention. The execution and delivery of this Agreement, the consummation of the transactions contemplated hereby and compliance with any of the provisions hereof by Sponsor do not and will not (a) conflict with or violate any provision of the organizational documents of Sponsor, (b) conflict with or violate any Law or Order applicable to Sponsor or any of its properties or assets, or (c) (i) violate, conflict with or result in a breach of, (ii) constitute a default (or an event which, with notice or lapse of time or both, would constitute a default) under, (iii) result in the termination, withdrawal, suspension, cancellation or modification of, (iv) accelerate the performance required by Sponsor under, (v) result in a right of termination or acceleration under, (vi) give rise to any obligation to make payments or provide compensation under, (vii) result in the creation of any Lien (other than Permitted Liens) upon any of the properties or assets of Sponsor under, (viii) give rise to any obligation to obtain any third party consent from any Person or (ix) give any Person the right to declare a default, exercise any remedy, accelerate the maturity or performance, cancel, terminate or modify any right, benefit, obligation or other term under, any of the terms, conditions or provisions of, any material Contract of Sponsor, except for any deviations from any of the foregoing clauses (b) or (c) that 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.

1.5 Subject 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, other than Liens pursuant to this Agreement, the SPAC Letter Agreement (as defined below), the SPAC Articles or applicable federal or state securities Laws. Sponsor does not own legally or beneficially any SPAC Securities other than the SPAC Securities set forth opposite Sponsor’s name on Schedule A hereto. Sponsor has the sole right to vote any Subject Securities that are entitled to vote, and none of such Subject Securities is subject to any voting trust or other agreement, arrangement or restriction with respect to the voting of such Subject Securities, except as contemplated by this Agreement and the SPAC Letter Agreement. For the avoidance of doubt, the first sentence in this Section 1.5 refers to “beneficial owner” of the title to the SPAC Securities and does not refer to “beneficial owner” of such securities as the term is used under Section 13(d) of the Exchange Act.

1.6 Business Combination Agreement. Sponsor understands and acknowledges that SPAC and the Company are entering into the Business Combination Agreement in reliance upon Sponsor’s execution and delivery of this Agreement. Sponsor has received a copy of the Business Combination Agreement and is familiar with the provisions of the Business Combination Agreement.

1.7 Adequate Information. Sponsor is a sophisticated securityholder and has adequate information concerning the business and financial condition of SPAC 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 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 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 Securities held by Sponsor are irrevocable unless the Business Combination Agreement is terminated in accordance with its terms and shall only terminate upon the termination of this Agreement.

1.8 Restricted Securities. Sponsor understands that the PubCo securities that Sponsor may receive or continue to hold in respect of its Subject Securities in connection with the Domestication and the Transactions will be “restricted securities” under applicable U.S. federal and state securities Laws and that, pursuant to these Laws, Sponsor must hold such PubCo securities indefinitely unless (a) they are registered with the SEC and qualified by state authorities, or (b) an exemption from such registration and qualification requirements is available, and that any certificates or book entries representing such PubCo securities shall contain a legend to such effect.
