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”),
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, 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 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 has never been convicted of,
or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another
person, or (iii) pertaining to any dealings in any securities and such Insider is not 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, 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.

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 released 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 (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 does not complete an initial Business Combination within the
required time period set forth in the Charter or (ii) with respect to any other 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 other 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).

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) following the completion of
an initial Business Combination, the date 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 sub-divisions, share capitalizations, share consolidations, reorganizations, recapitalizations and other similar transactions)
for any 20 trading days within a 30-trading day period commencing at least 120 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 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, Private
Placement Warrants and Ordinary Shares underlying the 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 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 any forward purchase agreement or similar
arrangement or in connection with the consummation of a Business Combination at prices no greater than the price at which the
Founder Shares, Private Placement Warrants or Ordinary Shares, as applicable, were originally purchased; (f) by virtue of the
Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (g) to the Company for no value for cancellation
in connection with the consummation of an initial Business Combination, (h) in the event of the Company’s liquidation prior
to the completion of a Business Combination; or (i) 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 (f) these permitted transferees must enter into a written agreement agreeing
to be bound by these transfer restrictions.

(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 Citigroup Global Markets Inc., 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 6(h) 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.

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 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 outstanding at such time.


 


12.             
Entire Agreement. This Letter Agreement constitutes the entire agreement and understanding of the parties hereto

13.             
Assignment. 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.


 


14.             
Counterparts. This Letter Agreement may be executed in any number of original or facsimile counterparts, and

15.             
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.


 


16.              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.

17.

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.


 


18.             
Notices. Any notice, consent or request to be given in connection with any of the terms or provisions of this
