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 Director (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,

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, Private
Placement 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 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 (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 material 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 and Private Placement 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, Private Placement 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 material 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).


 




    	 



    


    

 


(c)
The undersigned acknowledges and agrees that, prior to entering into a definitive agreement for a Business Combination with a
target business that is affiliated with the undersigned or any other Insiders of the Company or their affiliates, such transaction
must be approved by a majority of the Company’s disinterested independent directors and the Company will, to the extent
required by applicable law or the Company’s board of directors, obtain an opinion from an independent investment banking
firm or an independent accounting firm that such Business Combination is fair to the Company from a financial point of view.


 


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
sub-divisions, share capitalizations, share consolidations, reorganizations, recapitalizations and the like) 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 Shares 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
Shares are permitted (a) to the Company’s officers or directors, any affiliates or family members of any of the Company’s
officers or directors, any direct or indirect members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor,
including to funds affiliated with TCMI, Inc. (“TCV.”), and to direct or indirect members or partners of funds affiliated
with TCV or any affiliates thereof, 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 the consummation of a Business Combination at prices
no greater than the price at which the Founder Shares or Private Placement 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 (j) 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 the Representatives, Transfer any Ordinary Shares 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.


 


Subject
to the preceding paragraph, the Company will, to the fullest extent permitted by law, indemnify, exonerate and hold the Sponsor
and its managers and partners, and each of their respective partners, shareholders, members, affiliates, associated investment
funds, directors, officers, fiduciaries, managers, controlling persons, employees and agents and each of the partners, shareholders,
members, affiliates, associated investment funds, directors, officers, fiduciaries, managers, controlling persons, employees and
agents of each of the foregoing, whether or not a signatory hereto (collectively, the “Indemnitees”) free and harmless
from and against any and all actions, causes of action, suits, claims, liabilities, losses, damages and costs and expenses (including
attorneys' fees and expenses) incurred by an Indemnitee or any of them (collectively, the “Indemnified Liabilities”),
arising out of or in connection with any action, cause of action, suit, arbitration, investigation or claim arising out of, or
in any way relating to (i) this Letter Agreement, the Public Offering, any completed, abandoned or failed Business Combination
or any other agreement or arrangement in connection with the Public Offering or any completed, abandoned or failed Business Combination,
or any review or approval of any proposed, abandoned, failed or completed Business Combination or any proxy or other solicitation
of shareholder approval or authorization of any proposed, abandoned, failed or completed Business Combination, (ii) any investment
opportunities sourced by the Indemnitees, (iii) any act or omission of an Indemnitee in connection with the Company's or its affiliates'
affairs or (iv) the operations of, or services provided by an Indemnitee to, the Company or any of its affiliates, whether arising
prior to or on and after the date hereof and shall advance costs and expenses (including attorneys’ fees and expenses) incurred
by the Indemnitee in connection with any of the foregoing upon and following receipt of an undertaking from the applicable Indemnitee
to repay (without interest) any amounts advanced if indemnification hereunder is finally judicially determined by a court of competent
jurisdiction to not be owed; provided, that if and to the extent that the foregoing indemnification or advancement rights may
be unavailable or unenforceable for any reason, the Company hereby agrees to make the maximum contribution to the payment and
satisfaction of each of the Indemnified Liabilities which is permissible under applicable law. The rights of any Indemnitee to
indemnification or advancement hereunder will be primary and in addition to any other rights any such person may have under any
other agreement or instrument to which such Indemnitee is or becomes a party or is or otherwise becomes a beneficiary or under
law or regulation. In addition, the rights of any Indemnitee to indemnification hereunder will not entitle such Indemnitee to
access the funds held in the Trust Account, as defined above, and any indemnification hereunder will not be permitted to be funded
by funds held in the Trust Account. Each Indemnitee (as defined herein) is an intended third party beneficiary of this paragraph,
whether or not such Indemnitee is a signatory to this Letter Agreement.


 




    	 



    


    

 


11.
Forfeiture of Founder Shares. To the extent that the Underwriters do not exercise their option to purchase additional Ordinary
Shares 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 (excluding the Private
Placement 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 (excluding the Private Placement
Shares) and Founder Shares outstanding at such time.


 


12.
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.


 


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 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.


 


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.
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.


 


18.
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 transmission.
