      one-half of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder thereof to purchase one Ordinary Share at a price of $11.50 per share, subject to
      adjustment. The Units will be sold in the Public Offering pursuant to a registration statement on Form S-1 and a prospectus (the “Prospectus”) filed by the Company with the U.S. Securities

    2.          Representations and Warranties.

    

    

    (a)          The Sponsor and each Insider, with
        respect to itself, herself or himself, represent and warrant to the Company that it, she or he has the full right and power, without violating any agreement to which it, she or he is bound (including, without limitation, any non-competition or
        non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement, as applicable, and to serve as an officer of the Company and/or a director on the Company’s Board of Directors (the “Board”) or as an advisor (“Advisor”), as applicable, and each Insider hereby consents to being named in the Prospectus, road show and any other
        materials as an officer and/or director of the Company or Advisor, as applicable.

    

    

    (b)          Each Insider represents and warrants,
        with respect to herself or himself, that such Insider’s biographical information furnished to the Company (including any such information included in the Prospectus) is true and accurate in all material respects and does not omit any material
        information with respect to such Insider’s background. The Insider’s questionnaire, except for the Insiders that are Advisors, furnished to the Company is true and accurate in all material respects. Each Insider represents and warrants that such
        Insider is not subject to or a respondent in any legal action for, any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering of securities in any jurisdiction; such Insider

        currently a defendant in any such criminal proceeding; and such Insider has never been suspended or expelled from membership in any securities or commodities exchange or association or had a securities or commodities license or registration denied,
        suspended or revoked.

    

    

    3.          Business Combination Vote. It is acknowledged and
        agreed that the Company shall not enter into a definitive agreement regarding a proposed Business Combination without the prior consent of the Sponsor. The Sponsor and each Insider, with respect to itself, or herself or himself, agrees that if the
        Company seeks shareholder approval of a proposed initial Business Combination, then in connection with such proposed initial Business Combination, it, she or he, as applicable, shall vote all Founder Shares and any Public Shares held by it, her or
        him, as applicable, in favor of such proposed initial Business Combination (including any proposals recommended by the Board in connection with such Business Combination) and not redeem any Public Shares held by it, her or him, as applicable, in
        connection with such shareholder approval.

    

    

    
      2

      
        


    

    4.          Failure to Consummate a Business Combination; Trust
          Account Waiver.

    

    

    (a)          The Sponsor and each Insider hereby
        agree, with respect to itself, herself or himself, that in the event that the Company fails to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor and each Insider shall take all reasonable steps
        to cause the Company to (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than 10 business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash,
        equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously release to the Company to pay income taxes (less up to $100,000 of interest to pay dissolution
        expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any); and (iii) as
        promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Board, liquidate and dissolve, subject in the case of clauses (ii) and (iii) to the Company’s obligations under
        Cayman Islands law to provide for claims of creditors and in all cases subject to the other requirements of applicable law. The Sponsor and each Insider agree not to propose any amendment to the Charter (A) that would modify the substance or timing
        of the Company’s obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete an initial
        Business Combination within the required time period set forth in the Charter or (B) with respect to any provision relating to the rights of holders of Public Shares unless the Company provides its Public Shareholders with the opportunity to redeem
        their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously
        released to the Company to pay taxes, if any, divided by the number of then-outstanding Public Shares.

    

    

    (b)          The Sponsor and each Insider, with
        respect to itself, herself or himself, acknowledges that it, she or he has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company
        with respect to the Founder Shares held by it, her or him, if any. The Sponsor and each of the Insiders hereby further waive, with respect to any Founder Shares and Public Shares held by it, her or him, as applicable, any redemption rights it, she
        or he may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a shareholder vote to approve such Business Combination or a shareholder vote to approve an
        amendment to the Charter (i) that would modify the substance or timing of the Company’s obligation to provide holders of the Public Shares the right to have their shares redeemed in connection with an initial Business Combination or to redeem 100%
        of the Public Shares if the Company has not consummated an initial Business Combination within the time period set forth in the Charter or (ii) with respect to any provision relating to the rights of holders of Public Shares (although the Sponsor
        and the Insiders shall be entitled to liquidation rights with respect to any Public Shares they hold if the Company fails to consummate a Business Combination within the required time period set forth in the Charter).

    

    

    
      3

      
        


    

    5.          Lock-up; Transfer Restrictions.

    

    

    (a)          The Sponsor and the Insiders agree that
        they shall not Transfer any Founder Shares (the “Founder Shares Lock-up”) until the earliest of (A) one year after the completion of an initial Business Combination and (B) the date
        following the completion of an initial Business Combination on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s shareholders having the right to exchange their
        Ordinary Shares for cash, securities or other property (the “Founder Shares Lock-up Period”). Notwithstanding the foregoing, if, subsequent to a Business Combination, the closing price of
        the Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, share consolidations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing
        at least 150 days after the Company’s initial Business Combination, the Founder Shares shall be released from the Founder Shares Lock-up.

    

    

    (b)          The Sponsor and Insiders agree that they
        shall not effectuate any Transfer of the Private Placement Warrants or Ordinary Shares underlying such warrants until 30 days after the completion of an initial Business Combination.

    

    

    (c)          Notwithstanding the provisions set forth
        in paragraphs 5(a) and (b), Transfers of the Founder Shares and Private Placement Warrants are permitted (a) to the Company’s officers or directors, any affiliate or family member of any of the Company’s officers or directors, any
        members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (b) in the case of an individual, by gift to a member of one of the individual’s immediate family, any estate planning
        vehicle or to a trust, the beneficiary of which is a member of the individual’s immediate family, an affiliate of such person or to a charitable organization; (c) in the case of an individual, by virtue of laws of descent and distribution upon
        death of the individual; (d) in the case of an individual, pursuant to a qualified domestic relations order; (e) by private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at
        which the Founder Shares, or Private Placement Warrants, as applicable, were originally purchased; (f) pro rata distributions from the Sponsor to its members, partners, or stockholders pursuant to the Sponsor’s operating agreement; (g) by virtue of
        the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (h) to the Company for no value for cancellation in connection with the consummation of an initial Business Combination; (i) in the event of the Company’s
        liquidation prior to the completion of a Business Combination; or (j) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the Company’s Public Shareholders having the right to
        exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of an initial Business Combination; provided, however, that in the case of clauses (a) through (g) these permitted transferees must
        enter into a written agreement agreeing to be bound by these transfer restrictions.

    

    

    
      4

      
        


    

    (d)          During the period commencing on the
        effective date of the Underwriting Agreement and ending 180 days after such date, the Sponsor and each Insider shall not, without the prior written consent of the Underwriter, Transfer any Units, Ordinary Shares, Warrants or any other securities
        convertible into, or exercisable or exchangeable for, Ordinary Shares held by it, her or him, as applicable, subject to certain exceptions enumerated in Section 5(g) of the Underwriting Agreement.

    

    

    6.          Remedies. The Sponsor and each of the Insiders hereby
        agree and acknowledge that (i) each of the Underwriters and the Company would be irreparably injured in the event of a breach by the Sponsor or such Insider of its, her or his obligations, as applicable under paragraphs 3, 4, 5,
        7, 10 and 11, (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in
        equity, in the event of such breach.

    

    

    7.          Payments by the Company. Except as disclosed in the
        Prospectus, neither the Sponsor nor any affiliate of the Sponsor nor any director or officer of the Company nor any affiliate of the officers shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any
        payment of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s initial Business Combination (regardless of the type of transaction that it is).

    

    

    8.          Director and Officer Liability Insurance. The Company
        will maintain an insurance policy or policies providing directors’ and officers’ liability insurance, and the Insiders shall be covered by such policy or policies, in accordance with its or their terms, to the maximum extent of the coverage
        available for any of the Company’s directors or officers.

    

    

    9.          Termination. This Letter Agreement shall terminate on
        the earlier of (i) the expiration of the Founder Shares Lock-up Period and (ii) the liquidation of the Company.

    

    

    10.          Indemnification. In the event of the liquidation of
        the Trust Account upon the failure of the Company to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor (the “Indemnitor”) agrees to
        indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or defending
        against any litigation, whether pending or threatened) to which the Company may become subject as a result of any claim by (i) any third party for services rendered or products sold to the Company (except for the Company’s independent auditors) or
        (ii) any prospective target business with which the Company has discussed entering into a transaction agreement (a “Target”); provided, however, that such indemnification
        of the Company by the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party for services rendered or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to
        below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.00 per Public Share due to reductions in the value of the
        trust assets, in each case net of interest that may be withdrawn to pay the Company’s tax obligations, (y) shall not apply to any claims by a third party or Target who executed a waiver of any and all rights to the monies held in the Trust Account
        (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. The Indemnitor
        shall have the right to defend against any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of the claim to the Indemnitor, the Indemnitor notifies the Company in
        writing that it shall undertake such defense.

    

    

    
      5

      
        


    

    11.          Forfeiture of Founder Shares. To the extent that the
        Underwriters do not exercise their option to purchase additional Units within 45 days from the date of the Prospectus in full (as further described in the Prospectus), the Sponsor agrees to automatically surrender to the Company for no
        consideration, for cancellation at no cost, an aggregate number of Founder Shares so that the number of Founder Shares will equal of 20% of the sum of the total number of Ordinary Shares and Founder Shares outstanding at such time. The Sponsor and
        Insiders further agree that to the extent that the size of the Public Offering is increased or decreased, the Company will effect a share capitalization or a share repurchase, as applicable, with respect to the Founder Shares immediately prior to
        the consummation of the Public Offering in such amount as to maintain the number of Founder Shares at 20% of the sum of the total number of Ordinary Shares and Founder Shares to be outstanding immediately after the consummation of the Public
        Offering.

    

    

    12.          Right of First Offer. Subject to the terms and
        conditions of this paragraph 12, if, in connection with or prior to the closing of the initial Business Combination, the Company proposes to raise additional capital by issuing any equity securities, or securities convertible into,
        exchangeable or exercisable for equity securities (such securities, “New Equity Securities”), the Company shall first make an offer of the New Equity Securities to the Sponsor in
        accordance with the following provisions of this paragraph 12 (the “Right of First Offer”):

    

    

    (a)          Offer
          Notice.

    

    

    (i) Within two (2) Business Days following execution of a written letter of intent between the Company and the Target in connection
      with the Business Combination (the “Business Combination LOI”), the Company shall (a) deliver the Business Combination LOI to the Sponsor and (b) use its reasonable best efforts to request
      that the Target deliver to the Sponsor (and allow the Sponsor to deliver to potential purchasers of New Equity Securities as well as potential Third Party Purchasers (as defined below)) customary due diligence materials for an investment in New
      Equity Securities (subject to applicable confidentiality obligations), as promptly as practicable, including financial models, financial statements, dataroom access, access to the Target’s management team, and other materials that may be reasonably
      requested by the Sponsor (the “Marketing Materials”).

    

    

    
      6

      
        


    

    (b)          Exercise
          of Right of First Offer.

    

    

    (i) The Sponsor shall have a period of five (5) Business Days following its receipt of the Business Combination LOI (the “Initial Offer Period”) to deliver a bona fide binding written offer (the “ROFO Offer Notice”)
      to the Company (the “Sponsor Offer”) to purchase such New Equity Securities on the terms specified in the ROFO Offer Notice (the “Sponsor
        Offer Terms”).  If the Sponsor does not deliver an ROFO Offer Notice to the Company during the Initial Offer Period, the provisions of this paragraph 12 shall be deemed terminated and the Right of First Offer shall be deemed expired.
      If the Sponsor delivers a ROFO Offer Notice to the Company during the ROFO Notice Period, the Company may thereafter determine, within five (5) Business Days following its receipt of the ROFO Offer Notice, in its sole discretion, to (A) accept the
      ROFO Offer by delivery of a written notice to the Sponsor (an “Acceptance Notice”) or (B) reject the ROFO Offer.

    

    

    (ii) If the Company does not deliver, or has not yet delivered, an Acceptance Notice  following receipt of a timely ROFO Offer Notice,
      then in the event that (A) the Company receives a bona fide written offer from a third party (a “Third Party Purchaser”) to purchase New Equity
      Securities that the Company desires to accept, the Company must promptly deliver a written notice to the Sponsor setting forth the terms of such offer (the “Third Party Offer Terms”) and (B)
      if the Third Party Offer Terms, in the reasonable business judgment of the Board of Managers of the Sponsor, are the same as or worse than the Sponsor Offer Terms, taken as a whole (such offer, an “Inferior
        Third Party Offer”), the Company must deliver a written notice (a “Third Party Offer Notice”) to the Sponsor offering the Sponsor the right to purchase New Equity Securities on the
      Third Party Offer Terms.  The Sponsor shall have a period of two (2) Business Days following receipt of the Third Party Offer Notice (the “Match Period”) to deliver to the Company a bona fide written binding offer to purchase New Equity Securities on the Third Party Offer Terms (the “Matched Offer”). The Company shall not enter into
      a definitive binding agreement to accept any Inferior Third Party Offer unless (x) the Sponsor fails to deliver a Matched Offer to the Company during the Match Period with respect to such Inferior Third Party Offer or (y) the Company shall have
      timely delivered an Acceptance Notice.

    

    

    (c)          Assignment
          of Right of First Offer. The Right of First Offer may be assigned in whole or in part by the Sponsor to any of its members without the consent of the Company. Following any such assignment, the Company and any such assignee shall comply
        with the provisions set forth in this paragraph 12 with respect to the Right of First Offer as if such assignee were a party hereto.

    

    

    13.          Entire Agreement. This Letter Agreement constitutes
        the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate
        in any way to the subject matter hereof or the transactions contemplated hereby. This Letter 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.

    

    

    14.          Assignment. Other than with respect to paragraph
          12, No party hereto may assign either this Letter Agreement or any of its rights, interests, or obligations hereunder without the prior written consent of the other parties. Any purported assignment in violation of this paragraph shall be
        void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee. This Letter Agreement shall be binding on the Sponsor, each of the Insiders and each of their respective successors, heirs, personal
        representatives and assigns and permitted transferees.

        in any number of original or facsimile counterparts, and each of such counterparts shall for all purposes be deemed to be an original, and all such counterparts shall together constitute but one and the same instrument.

    

    

    16.          Effect of Headings. The paragraph headings herein
        are for convenience only and are not part of this Letter Agreement and shall not affect the interpretation thereof.

    

    

    17.          Severability. This Letter Agreement shall be deemed
        severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this Letter Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or
        unenforceable term or provision, the parties hereto intend that there shall be added as a part of this Letter Agreement a provision as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

    

    

    18.          Governing Law. This Letter Agreement shall be
        governed by and construed and enforced in accordance with the laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The parties
        hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this Letter Agreement shall be brought and enforced in the courts of New York City, in the State of New York, and irrevocably submit to
        such jurisdiction and venue, which jurisdiction and venue shall be exclusive, and (ii) waive any objection to such exclusive jurisdiction and venue or that such courts represent an inconvenient forum.

    

    

    19.          Notices. Any notice, consent or request to be given
        in connection with any of the terms or provisions of this Letter Agreement shall be in writing and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery or facsimile
