(whether annual or special and whether or not an adjourned or postponed meeting, however called and including any adjournment or postponement thereof), for the purpose of approving any or all of the resolutions set forth in the Proxy. In addition,
prior to the Termination Date (as defined herein), the Shareholder irrevocably and unconditionally agrees that, at any meeting of the shareholders of the Company (whether annual or special and whether or not an adjourned or postponed meeting,
however called and including any adjournment or postponement thereof) and in connection with any written consent of shareholders of the Company, the Shareholder shall, and shall cause any other holder of record of any of the Shareholder’s
Covered Shares to: 
 (a) if and when such meeting is held, appear at such meeting or otherwise cause the Shareholder’s Covered Shares
to be counted as present thereat for the purpose of establishing a quorum, and if a quorum is not present, to vote (in person or by proxy) in favor of adjournment of such meeting of the shareholders to a later date, as in accordance with the
Company’s Articles of Association as in effect at such time; 
 (b) execute and return an action by written consent (or vote, in person
or by proxy), or validly execute and return and cause such consent to be granted with respect to (or cause to be voted at such meeting), all of the Shareholder’s Covered Shares owned as of the date that any written consent is executed by the
Shareholder (or the record date for such meeting) in favor of the Company Shareholder Proposals, as set forth on Exhibit A hereto; 

(c) execute and return an action by written consent (or vote, in person or by proxy), or validly execute and return and cause such consent to
be granted with respect to (or cause to be voted at such meeting), all of the Shareholder’s Covered Shares against (A) any Company Acquisition Proposal (as defined in the Business Combination Agreement) or any Company Business Combination

adversely affect the Transactions (including the consummation thereof), (ii) result in a breach of any covenant, 

  
 2 













 
representation or warranty or other obligation or agreement of the Company under the Business Combination Agreement, this Agreement or the Registration Rights Agreement or cause any of the
conditions to Closing set forth in Article VI of the Business Combination Agreement not to be fulfilled or (iii) result in a breach of any covenant, representation or warranty or other obligation or agreement of the Shareholder contained in
this Agreement or the Registration Rights Agreement and (B) any merger agreement or merger (other than the Business Combination Agreement and the Merger), consolidation, combination, sale of all or substantially all assets, scheme of
arrangement, reorganization, recapitalization, dissolution, liquidation or winding up of or by the Company, in each case as determined by the Company; and 

(d) in any other circumstances upon which a consent or other approval is required under the Company’s Governing Documents or otherwise
sought in furtherance of the Transactions, in each case as determined by the Company, vote, consent or approve (or cause to be voted, consented or approved), in person or by proxy, all of the Shareholder’s Covered Shares owned at such time in
favor thereof. 
 2. Proxy. 
 (a) The
obligations of the Shareholder specified in Section 1 shall apply whether or not the Merger or any action described above is recommended by the board of directors of the Company or any committee thereof or the board of
directors of the Company or any committee thereof has previously recommended the Merger or such action but changed such recommendation. 

(b) The Shareholder hereby irrevocably and unconditionally, to the fullest extent permitted by applicable Law, appoints the Company, or any
designee of the Company, for so long as the provisions of Section 1 remain in effect, as the Shareholder’s attorney-in-fact and proxy with
full power of substitution, to vote, express consent or dissent and otherwise act (by written consent or otherwise) with respect to the Covered Shares, solely on the matters and in the manner specified in Section 1. This
proxy (including, for the avoidance of doubt, any voting proxy delivered pursuant to Section 1) shall be valid for the duration of this Agreement. 

(c) THE PROXIES AND POWERS OF ATTORNEY GRANTED PURSUANT TO THIS SECTION 2 ARE IRREVOCABLE AND COUPLED WITH AN INTEREST. The Shareholder
hereby affirms that the irrevocable proxy granted by Shareholder pursuant to this Section 2 (including, for the avoidance of doubt, any voting proxy delivered pursuant to Section 1) is granted in
consideration of SPAC entering into this Agreement and the Business Combination Agreement and that such irrevocable proxy is given to secure the performance of the duties of the Shareholder under this Agreement. The proxies and powers of attorney
shall not be terminated by any act of the Shareholder or by operation of law, by lack of appropriate power or authority, or by the occurrence of any other event or events and shall be binding upon all successors, assigns, heirs, beneficiaries and
legal representatives of the Shareholder. The Shareholder hereby revokes all other proxies and powers of attorney on the matters specified in this Section 2 with respect to the Covered Shares that the Shareholder may have
previously appointed or granted, and no subsequent proxy or power of attorney shall be given or written consent executed (and if given or executed, shall not be effective) by the Shareholder with respect to any Covered Shares. All authority herein
conferred or agreed to be conferred shall survive the death, bankruptcy or incapacity of the Shareholder and any obligation of the Shareholder under this Agreement shall be binding upon the heirs, personal representatives, and successors of the
Shareholder.

 3. No Inconsistent Agreements. The Shareholder hereby covenants and agrees that the Shareholder shall
not, at any time prior to the Termination Date (as defined below), (i) enter into any voting agreement or voting trust with respect to any of the Shareholder’s Covered Shares that is inconsistent with the Shareholder’s obligations pursuant
to this Agreement, (ii) grant a proxy or power of attorney with respect to any of the Shareholder’s Covered Shares that is inconsistent with the Shareholder’s obligations pursuant to this Agreement, or (iii) enter into any
agreement or undertaking that is otherwise inconsistent with, or would interfere with, or prohibit or prevent it from satisfying, its obligations pursuant to this Agreement. 

4. Termination. This Agreement shall terminate, and no party shall have any further obligations or liabilities under this Agreement, upon the earliest
of (i) termination of the Business Combination Agreement in accordance with its terms or (ii) the time this Agreement is terminated upon the mutual written agreement of SPAC, the Company and the Shareholder (the earliest such date under
clauses (i) and (ii) being referred to herein as the “Termination Date”); provided, that the provisions set forth in Sections 11 to 23 below shall survive the termination of this Agreement;
provided further, that termination of this Agreement shall not relieve any party hereto from any liability for any willful breach of, or actual fraud in connection with, this Agreement prior to such termination. 

5. Representations and Warranties of the Shareholder. The Shareholder hereby represents and warrants to the Company and SPAC as to itself, as of the
date hereof and as of the Closing, as follows: 
 (a) The Shareholder is the sole record and beneficial owner (within the meaning of Rule 13d-3 under the Exchange Act) of, and has good, valid and marketable title to, the Covered Shares, free and clear of Liens other than as created by this Agreement or pursuant to the Governing Documents of the

instructions with respect to the matters set forth herein, in each case, with respect to the Shareholder’s Covered Shares, (ii) has not entered into any voting agreement or voting trust or any other agreement or arrangement, including any

change in the rights or obligations of any party under any Contract legally binding upon the Shareholder, except, in the case of clause (ii) or (iii) directly above, for any such breach, violation, termination, default, creation, acceleration
or change that would not, individually or in the aggregate, reasonably be expected to prevent or materially delay or impair the Shareholder’s ability to perform its obligations hereunder or to consummate the transactions contemplated hereby, or
the consummation of the Merger or the other transactions contemplated by the Business Combination Agreement.

Combination Agreement.

any manner permitted by Delaware law, and further consents to service of process by nationally recognized overnight courier service guaranteeing overnight delivery, or by registered or certified mail, return receipt requested, at its address
specified pursuant to Section 12. Notwithstanding the foregoing in this Section 16, any party hereto may commence any action, claim, cause of action or suit in a court other than the above-named
courts solely for the purpose of enforcing an order or judgment issued by one of the above-named courts. 
 (c) TO THE EXTENT NOT PROHIBITED
BY APPLICABLE LAW WHICH CANNOT BE WAIVED, EACH OF THE PARTIES HERETO AND ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY MAY DO SO ONLY IF HE, SHE OR IT IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT TO TRIAL BY JURY ON ANY CLAIMS OR
COUNTERCLAIMS ASSERTED IN ANY LEGAL DISPUTE RELATING TO THIS AGREEMENT AND FOR ANY COUNTERCLAIM RELATING THERETO, WHETHER NOW EXISTING OR HEREAFTER ARISING. IF THE SUBJECT MATTER OF ANY SUCH LEGAL DISPUTE IS ONE IN WHICH THE WAIVER OF JURY TRIAL IS
PROHIBITED, NO PARTY HERETO NOR ANY PERSON ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY SHALL ASSERT IN SUCH LEGAL DISPUTE A NONCOMPULSORY COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT. FURTHERMORE, NO PARTY HERETO NOR ANY PERSON
ASSERTING RIGHTS AS A THIRD-PARTY BENEFICIARY SHALL SEEK TO CONSOLIDATE ANY SUCH LEGAL DISPUTE WITH A SEPARATE ACTION OR OTHER PROCEEDING IN WHICH A JURY TRIAL CANNOT BE WAIVED. 

17. Assignment; Successors. No party hereto shall assign this Agreement or any part hereof without the prior written consent of the other parties.
Subject to the foregoing, this Agreement shall be binding upon and inure to the benefit of the parties hereto and their respective permitted successors and assigns. Any attempted assignment in violation of the terms of this
Section 17 shall be null and void, ab initio. 
 18. Non-Recourse. This
Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement or the transactions contemplated hereby may only be brought against, the entities that are expressly named as parties
hereto, and then only with respect to the specific obligations set forth herein with respect to such party. Except to the extent a named party to this Agreement (and then only to the extent of the specific obligations undertaken by such named party
in this Agreement), (a) no past, present or future director, officer, employee, incorporator, member, partner, shareholder, affiliate, agent, attorney, advisor or representative or affiliate of any named party to this Agreement and (b) no past,
present or future director, officer, employee, incorporator, member, partner, shareholder, affiliate, agent, attorney, advisor or representative or affiliate of any of the foregoing shall have any liability (whether in contract, tort, equity or
otherwise) for any one or more of the representations, warranties, covenants, agreements or other obligations or liabilities of any one or more of SPAC, the Company or the Shareholder under this Agreement of or for any claim based on, arising out
of, or related to this Agreement or the transactions contemplated hereby.

 19. Enforcement. The parties hereto agree that irreparable damage for which monetary damages, even if
available, would not be an adequate remedy, would occur in the event that the parties do not perform their obligations under the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. The parties
hereto acknowledge and agree that (a) the parties shall be entitled to an injunction, specific performance, or other equitable relief, to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof, including
the Shareholder’s obligations to vote its Covered Shares as provided in this Agreement, without proof of damages, prior to the valid termination of this Agreement, this being in addition to any other remedy to which they are entitled under this
Agreement, and (b) the right of specific enforcement is an integral part of the transactions contemplated by this Agreement and without that right, none of the parties would have entered into this Agreement. Each party agrees that it will not
oppose the granting of specific performance and other equitable relief on the basis that the other parties have an adequate remedy at applicable Law or that an award of specific performance is not an appropriate remedy for any reason at applicable
Law or equity. The parties acknowledge and agree that any party seeking an injunction to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement in accordance with this
Section 19 shall not be required to provide any bond or other security in connection with any such injunction. 
 20.
Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or
unenforceable under applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to
any party. Upon such determination that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties hereto as closely as possible in an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. 

21. Counterparts. This Agreement and any amendment hereto may be executed in one or more counterparts, each of which shall be deemed to be an original,
but all of which shall constitute one and the same agreement. Delivery of an executed counterpart of a signature page to this Agreement or any amendment hereto by electronic means, including docusign, e-mail,
or scanned pages shall be effective as delivery of a manually executed counterpart to this Agreement or any amendment hereto. 
 22. Interpretation and
Construction. The words “hereof,” “herein” and “hereunder” and words of like import used in this Agreement shall refer to this Agreement as a whole and not to any particular provision of this Agreement. The
descriptive headings used herein are inserted for convenience of reference only and are not intended to be part of or to affect the meaning or interpretation of this Agreement. References to Sections are to Sections of this Agreement unless
otherwise specified. Any singular term in this Agreement shall be deemed to include the plural, and any plural term the singular. The definitions contained in this Agreement are applicable to the 

  
 13 













 
masculine as well as to the feminine and neuter genders of such term. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall
be deemed to be followed by the words “without limitation,” whether or not they are in fact followed by those words or words of like import. “Writing,” “written” and comparable terms refer to printing, typing and other
means of reproducing words (including electronic media) in a visible form. References to any statute shall be deemed to refer to such statute as amended and to any rules or regulations promulgated thereunder. References to any Person include the
successors and permitted assigns of that Person. References from or through any date mean, unless otherwise specified, from and including such date or through and including such date, respectively. In the event an ambiguity or question of intent or
interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof will arise favoring or disfavoring any party by virtue of the authorship of any of the provisions of this
Agreement. 
 23. Capacity as a Shareholder. Notwithstanding anything herein to the contrary, the Shareholder signs this Agreement solely in the
Shareholder’s capacity as a shareholder of the Company, and not in any other capacity, and this Agreement shall not limit or otherwise affect the actions of the Shareholder or any Affiliate, employee or designee of the Shareholder or any of its
Affiliates in his or her capacity, if applicable, as an officer or director of the Company or any other Person. The Shareholder shall not be liable or responsible for any breach, default, or violation of any representation, warranty, covenant or
agreement hereunder by any other shareholder that is entering into a similar Agreement. 
 24. Trust Account Waiver. The Shareholder agrees that he,
she or it shall be subject to the terms and conditions of Section 8.18 (Trust Account Waiver) of the Business Combination Agreement as though the Shareholder were the Company thereunder and that Section 8.18 (as so modified) is
hereby incorporated into this Agreement, mutatis mutandis.
