of such loans may be convertible into up to an additional 1,000,000 Private Placement Warrants at a price of $1.50 per Private
Placement Warrant;


 


WHEREAS,
the Company is engaged in an initial public offering (the “Offering”) of the Company’s units, each
such unit comprised of one Ordinary Share and one-fifth of one Public Warrant (as defined below) (the “Units”)
and, in connection therewith, has determined to issue and deliver up to 57,500,000 redeemable warrants (including up to 7,500,000
redeemable warrants pursuant to the Over-allotment Option) to public investors in the Offering (the “Public Warrants”
and, together with the Private Placement Warrants and the Forward Purchase Warrants, the “Warrants”);


 


WHEREAS,
each whole Warrant entitles the holder thereof to purchase one Class A ordinary share of the Company, par value $0.0001 per share
(“Ordinary Shares”), for $11.50 per share, subject to adjustment as described herein;


 


WHEREAS,
the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration statement
on Form S-1, File No. 333-253316, and a prospectus (the “Prospectus”), for the registration, under the
Securities Act of 1933, as amended (the “Securities Act”), of the Units, the Public Warrants and the
Ordinary Shares included in the Units;


 


WHEREAS,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection
with the issuance, registration, transfer, exchange, redemption and exercise of the Warrants;


 






     


     


    

 


WHEREAS,
the Company desires to provide for the form and provisions of the Warrants, the terms upon which they shall be issued and exercised,
and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent and the holders of the Warrants;
and


 


WHEREAS,
all acts and things have been done and performed which are necessary to make the Warrants, when executed on behalf of the Company
and countersigned by or on behalf of the Warrant Agent (if a physical certificate is issued), as provided herein, the valid, binding
and legal obligations of the Company, and to authorize the execution and delivery of this Agreement.


 


NOW, THEREFORE,
in consideration of the mutual agreements herein contained, the parties hereto agree as follows:


 


		1.	Appointment of Warrant Agent. The Company hereby appoints the Warrant
Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and agrees to perform
the same in accordance with the terms and conditions set forth in this Agreement.



 


		2.	Warrants.



 


2.1 Form
of Warrant. Each Warrant shall initially be issued in registered form only.


 


2.2 Effect
of Countersignature. If a physical certificate is issued, unless and until countersigned by the Warrant Agent pursuant to this
Agreement, a certificated Warrant shall be invalid and of no effect and may not be exercised by the holder thereof.


 


2.3 Registration.


 


2.3.1
Warrant Register. The Warrant Agent shall maintain books (the “Warrant Register”) for the
registration of original issuance and the registration of transfer of the Warrants. Upon the initial issuance of the Warrants in
book-entry form, the Warrant Agent shall issue and register the Warrants in the names of the respective holders thereof in such
denominations and otherwise in accordance with instructions delivered to the Warrant Agent by the Company. Ownership of beneficial
interests in the Public Warrants shall be shown on, and the transfer of such ownership shall be effected through, records maintained
by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such institution,
with respect to a Warrant in its account, a “Participant”).


 


If the
Depositary subsequently ceases to make its book-entry settlement system available for the Public Warrants, the Company may instruct
the Warrant Agent regarding making other arrangements for book-entry settlement. In the event that the Public Warrants are not
eligible for, or it is no longer necessary to have the Public Warrants available in, book-entry form, the Warrant Agent shall provide
written instructions to the Depositary to deliver to the Warrant Agent for cancellation each book-entry Public Warrant, and the
Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical form evidencing such
Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto as Exhibit
A.


 


Physical
certificates, if issued, shall be signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer,
Chief Financial Officer, President, Secretary or other principal officer of the Company. In the event the person whose facsimile
signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before
such Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.


 


2.3.2
Registered Holder. Prior to due presentment for registration of transfer of any Warrant, the Company and the Warrant
Agent may deem and treat the person in whose name such Warrant is registered in the Warrant Register (the “Registered
Holder”) as the absolute owner of such Warrant and of each Warrant represented thereby (notwithstanding any notation
of ownership or other writing on any physical certificate made by anyone other than the Company or the Warrant Agent), for the
purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by
any notice to the contrary.


 






    2


     


    

 


2.4 Detachability
of Warrants. The Ordinary Shares and Public Warrants comprising the Units shall begin separate trading on the 52nd day following
the date of the Prospectus or, if such 52nd day is not on a day, other than a Saturday, Sunday or federal holiday, on which banks
in New York City are generally open for normal business (a “Business Day”), then on the immediately succeeding
Business Day following such date, or earlier (the “Detachment Date”) with the consent of Goldman, Sachs,
& Co. LLC and Morgan Stanley & Co. LLC, but in no event shall the Ordinary Shares and the Public Warrants comprising the
Units be separately traded until (A) the Company has filed a Current Report on Form 8-K with the Commission containing an audited
balance sheet reflecting the receipt by the Company of the gross proceeds of the Offering, including the proceeds then received
by the Company from the exercise by the underwriter of its right to purchase additional Units in the Offering (the “Over-allotment
Option”), if the Over-allotment Option is exercised prior to the filing of the Current Report on Form 8-K, and (B)
the Company issues a press release announcing when such separate trading shall begin.


 


2.5 Fractional
Warrants. The Company shall not issue fractional Warrants other than as part of the Units, each of which is comprised of one
Ordinary Share and one-fifth of one whole Public Warrant. If, upon the detachment of Public Warrants from the Units or otherwise,
a holder of Warrants would be entitled to receive a fractional Warrant, the Company shall round down to the nearest whole number
the number of Warrants to be issued to such holder.


 


2.6 Private
Placement Warrants; Forward Purchase Warrants.


 


2.6.1 The
Private Placement Warrants shall be identical to the Public Warrants, except that so long as they are held by the Sponsor or any
of its Permitted Transferees (as defined below) the Private Placement Warrants: (i) may be exercised for cash or on a “cashless
basis,” pursuant to subsection 3.3.1(b) hereof, (ii) including the Ordinary Shares issuable upon exercise of the Private
Placement Warrants, may not be transferred, assigned or sold until thirty (30) days after the completion by the Company of an initial
Business Combination, (iii) shall not be redeemable by the Company pursuant to Section 6.1 hereof and (iv) shall only be
redeemable by the Company pursuant to Section 6.2 if the Reference Value (as defined below) is less than $18.00 per share
(subject to adjustment in compliance with Section 4 hereof); provided, however, that in the case of clause (ii), the Private
Placement Warrants and any Ordinary Shares issued upon exercise of the Private Placement Warrants may be transferred by the holders
thereof:


 


(a) to
the Company’s officers or directors, any affiliates or family members 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 such individual’s immediate family, an affiliate of such individual or to a charitable organization;


 


(c) in
the case of an individual, by virtue of the laws of descent and distribution upon death of such 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 agreement or in connection with the
consummation of the Company’s Business Combination at prices no greater than the price at which the 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 its initial Business Combination;


 






    3


     


    

 


(h) in the event of
the Company’s liquidation prior to the completion of its initial Business Combination; or


 


(i) in
the event of the Company’s completion of a liquidation, merger, share exchange or other similar transaction which results
in all of the public shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent
to the completion of the Company’s initial Business Combination; provided, however, that, in the case of clauses
(a) through (f), these permitted transferees (the “Permitted Transferees”) must enter into a written
agreement with the Company agreeing to be bound by the transfer restrictions in this Agreement.


 


2.6.2 Forward
Purchase Warrants. The Forward Purchase Warrants shall have the same terms and be in the same form as the Public Warrants.


 


		3.	Terms and Exercise of Warrants.



 


3.1 Warrant
Price. Each whole Warrant shall entitle the Registered Holder thereof, subject to the provisions of such Warrant and of this
Agreement, to purchase from the Company the number of Ordinary Shares stated therein, at the price of $11.50 per share, subject
to the adjustments provided in Section 4 hereof and in the last sentence of this Section 3.1. The term “Warrant
Price” as used in this Agreement shall mean the price per share (including in cash or by payment of Warrants pursuant
to a “cashless exercise,” to the extent permitted hereunder) described in the prior sentence at which Ordinary Shares
may be purchased at the time a Warrant is exercised. The Company in its sole discretion may lower the Warrant Price at any time
prior to the Expiration Date (as defined below) for a period of not less than fifteen (15) Business Days (unless otherwise required
by the Commission, any national securities exchange on which the Warrants are listed or applicable law); provided that the Company
shall provide at least five (5) days’ prior written notice of such reduction to Registered Holders of the Warrants; and provided
further, that any such reduction shall be identical among all of the Warrants.


 


3.2
Duration of Warrants. A Warrant may be exercised only during the period (the “Exercise Period”)
(A) commencing on the later of: (i) the date that is thirty (30) days after the first date on which the Company completes a Business
Combination, and (ii) the date that is twelve (12) months from the date of the closing of the Offering, and (B) terminating at
the earliest to occur of (x) 5:00 p.m., New York City time on the date that is five (5) years after the date on which the Company
completes its initial Business Combination, (y) the liquidation of the Company in accordance with the Company’s amended
and restated memorandum and articles of association (as the same may be amended from time to time, the “Charter”)
if the Company fails to complete a Business Combination, and (z) other than with respect to the Private Placement Warrants then
held by the Sponsor or its Permitted Transferees with respect to a redemption pursuant to Section 6.1 hereof or, if the
Reference Value equals or exceeds $18.00 per share (subject to adjustment in compliance with Section 4 hereof), Section
6.2 hereof, 5:00 p.m., New York City time on the Redemption Date (as defined below) as provided in Section 6.3 hereof
(the “Expiration Date”); provided, however, that the exercise of any Warrant shall be subject to the
satisfaction of any applicable conditions, as set forth in subsection 3.3.2 below, with respect to an effective registration
statement or a valid exemption therefrom being available. Except with respect to the right to receive the Redemption Price (as
defined below) (other than with respect to a Private Placement Warrant then held by the Sponsor or its Permitted Transferees in
connection with a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00 per share
(subject to adjustment in compliance with Section 4 hereof), Section 6.2 hereof) in the event of a redemption (as
set forth in Section 6 hereof), each Warrant (other than a Private Placement Warrant then held by the Sponsor or its Permitted
Transferees in the event of a redemption pursuant to Section 6.1 hereof or, if the Reference Value equals or exceeds $18.00
per share (subject to adjustment in compliance with Section 4 hereof), Section 6.2 hereof) not exercised on or before
the Expiration Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall
cease at 5:00 p.m. New York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the
Warrants by delaying the Expiration Date; provided that the Company shall provide at least twenty (20) days prior written notice
of any such extension to Registered Holders of the Warrants and, provided further that any such extension shall be identical in
duration among all the Warrants.

3.3 Exercise
of Warrants.


 


3.3.1 Payment.
Subject to the provisions of the Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering
to the Warrant Agent at its corporate trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised,
or, in the case of a Warrant represented by a book-entry, the Warrants to be exercised (the “Book-Entry Warrants”)
on the records of the Depositary to an account of the Warrant Agent at the Depositary designated for such purposes in writing by
the Warrant Agent to the Depositary from time to time, (ii) an election to purchase (“Election to Purchase”)
any Ordinary Shares pursuant to the exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse
of the Definitive Warrant Certificate or, in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance
with the Depositary’s procedures, and (iii) the payment in full of the Warrant Price for each Ordinary Share as to which
the Warrant is exercised and any and all applicable taxes due in connection with the exercise of the Warrant, the exchange of the
Warrant for the Ordinary Shares and the issuance of such Ordinary Shares, as follows:


 


(a) in
lawful money of the United States, in good certified check or good bank draft payable to the order of the Warrant Agent;


 


(b)
with respect to any Private Placement Warrant, so long as such Private Placement Warrant is held by the Sponsor or a
Permitted Transferee, by surrendering the Warrants for that number of Ordinary Shares equal to (i) if in connection with a
redemption of Private Placement Warrants pursuant to Section 6.2 hereof, as provided in Section 6.2 hereof with
respect to a Make-Whole Exercise (as defined below) and (ii) in all other scenarios the quotient obtained by dividing (x) the
product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Sponsor
Exercise Fair Market Value” (as defined in this subsection 3.3.1(b)) over the Warrant Price by (y) the
Sponsor Exercise Fair Market Value. Solely for purposes of this subsection 3.3.1(b), the “Sponsor Exercise
Fair Market Value” shall mean the average last reported sale price of the Ordinary Shares for the ten (10)
trading days ending on the third (3rd) trading day prior to the date on which notice of exercise of the Private Placement
Warrant is sent to the Warrant Agent;


 


(c) on a cashless basis
as provided in Section 6.2 hereof with respect to a Make-Whole Exercise; or


 


(d) on a
cashless basis as provided in Section 7.4 hereof.


 


3.3.2 Issuance
of Ordinary Shares on Exercise. As soon as practicable after the exercise of any Warrant and the clearance of the funds in
payment of the Warrant Price (if payment is pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered
Holder of such Warrant a book-entry position or certificate, as applicable, for the number of Ordinary Shares to which he, she
or it is entitled, registered in such name or names as may be directed by him, her or it on the register of members of the Company,
and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned Warrant, as applicable, for
the number of Ordinary Shares as to which such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company
shall not be obligated to deliver any Ordinary Shares pursuant to the exercise of a Warrant and shall have no obligation to settle
such Warrant exercise unless a registration statement under the Securities Act with respect to the Ordinary Shares underlying the
Public Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s satisfying its obligations
under Section 7.4 or a valid exemption from registration is available. No Warrant shall be exercisable and the Company shall
not be obligated to issue Ordinary Shares upon exercise of a Warrant unless the Ordinary Shares issuable upon such Warrant exercise
have been registered, qualified or deemed to be exempt from registration or qualification under the securities laws of the state
of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered Holder of
Warrants may exercise its Warrants only for a whole number of Ordinary Shares. The Company may require holders of Public Warrants
to settle the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants
on a “cashless basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a
fractional interest in an Ordinary Share, the Company shall round down to the nearest whole number, the number of Ordinary Shares
to be issued to such holder.


 


3.3.3 Valid
Issuance. All Ordinary Shares issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly
issued, fully paid and nonassessable.


 






    5


     


    

 


3.3.4 Date
of Issuance. Each person in whose name any book-entry position or certificate, as applicable, for Ordinary Shares is issued
and who is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record
of such Ordinary Shares on the date on which the Warrant, or book-entry position representing such Warrant, was surrendered and
payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated Warrant,
except that, if the date of such surrender and payment is a date when the register of members of the Company or book-entry system
of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares at the close of business
on the next succeeding date on which the share transfer books or book-entry system are open.


 


3.3.5 Maximum
Percentage. A holder of a Warrant may notify the Company in writing in the event it elects to be subject to the provisions
contained in this subsection 3.3.5; however, no holder of a Warrant shall be subject to this subsection 3.3.5 unless
he, she or it makes such election. If the election is made by a holder, the Warrant Agent shall not effect the exercise of the
holder’s Warrant, and such holder shall not have the right to exercise such Warrant, to the extent that after giving effect
to such exercise, such person (together with such person’s affiliates), to the Warrant Agent’s actual knowledge, would
beneficially own in excess of 4.9% or 9.8% (as specified by such holder) (the “Maximum Percentage”) of
the Ordinary Shares outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate
number of Ordinary Shares beneficially owned by such person and its affiliates shall include the number of Ordinary Shares issuable
upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude Ordinary
Shares that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such
person and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the
Company beneficially owned by such person and its affiliates (including, without limitation, any convertible notes or convertible
preferred shares or warrants) subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except
as set forth in the preceding sentence, for purposes of this paragraph, beneficial ownership shall be calculated in accordance
with Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). For purposes
of the Warrant, in determining the number of outstanding Ordinary Shares, the holder may rely on the number of outstanding Ordinary
Shares as reflected in (1) the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report
on Form 8-K or other public filing with the Commission as the case may be, (2) a more recent public announcement by the Company
or (3) any other notice by the Company or Continental Stock Transfer & Trust Company, as transfer agent (in such capacity,
the “Transfer Agent”), setting forth the number of Ordinary Shares outstanding. For any reason at any
time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm orally and
in writing to such holder the number of Ordinary Shares then outstanding. In any case, the number of issued and outstanding Ordinary
Shares shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the holder
and its affiliates since the date as of which such number of issued and outstanding Ordinary Shares was reported. By written notice
to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder
to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first
(61st) day after such notice is delivered to the Company.


 


		4.	Adjustments.



 


4.1 Share
Capitalizations.


 


4.1.1 Sub-Divisions.
If after the date hereof, and subject to the provisions of Section 4.6 below, the number of issued and outstanding Ordinary
Shares is increased by a capitalization or share dividend of Ordinary Shares, or by a split-up of Ordinary Shares or other similar
event, then, on the effective date of such capitalization or share dividend, split-up or similar event, the number of Ordinary
Shares issuable on exercise of each Warrant shall be increased in proportion to such increase in the issued and outstanding Ordinary
Shares. A rights offering made to all or substantially all holders of Ordinary Shares entitling holders to purchase Ordinary Shares
at a price less than the “Historical Fair Market Value” (as defined below) shall be deemed a share dividend of a number
of Ordinary Shares equal to the product of (i) the number of Ordinary Shares actually sold in such rights offering (or issuable
under any other equity securities sold in such rights offering that are convertible into or exercisable for Ordinary Shares) and
(ii) one (1) minus the quotient of (x) the price per Ordinary Share paid in such rights offering divided by (y) the Historical
Fair Market Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into
or exercisable for Ordinary Shares, in determining the price payable for Ordinary Shares, there shall be taken into account any
consideration received for such rights, as well as any additional amount payable upon exercise or conversion and (ii) “Historical
Fair Market Value” means the volume weighted average price of the Ordinary Shares during the ten (10) trading day
period ending on the trading day prior to the first date on which the Ordinary Shares trade on the applicable exchange or in the
applicable market, regular way, without the right to receive such rights. No Ordinary Shares shall be issued at less than their
par value.


 






    6


     


    

 


4.1.2 Extraordinary
Dividends. If the Company, at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of
the holders of the Ordinary Shares a dividend or make a distribution in cash, securities or other assets on account of such Ordinary
Shares (or other shares of the Company’s share capital into which the Warrants are convertible), other than (a) as described
in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined below), (c) to satisfy the redemption rights of the holders
of the Ordinary Shares in connection with a proposed initial Business Combination, (d) to satisfy the redemption rights of the
holders of the Ordinary Shares in connection with a shareholder vote to amend the Company’s amended and restated memorandum
and articles of association (i) to modify the substance or timing of the Company’s obligation to provide holders of Ordinary
Shares the right to have their shares redeemed in connection with the Company’s initial Business Combination or to redeem
100% of the Company’s Ordinary Shares included in the Units sold in the Offering (the “Public Shares”)
if the Company does not complete its initial Business Combination within the time period required by the Company’s amended
and restated memorandum and articles of association, as amended from time to time, or (ii) with respect to any other provision
relating to the rights of holders of Ordinary Shares or pre-initial Business Combination activity or (e) in connection with the
redemption of Public Shares upon the failure of the Company to complete its initial Business Combination and any subsequent distribution
of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”),
then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the
amount of cash and/or the fair market value (as determined by the Company’s board of directors (the “Board”),
in good faith) of any securities or other assets paid on each Ordinary Share in respect of such Extraordinary Dividend. For purposes
of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution
which, when combined on a per share basis with the per share amounts of all other cash dividends and cash distributions paid on
the Ordinary Shares during the 365-day period ending on the date of declaration of such dividend or distribution does not exceed
$0.50 (as adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding
cash dividends or cash distributions that resulted in an adjustment to the Warrant Price or to the number of Ordinary Shares issuable
on exercise of each Warrant but only with respect to the amount of aggregate cash dividends and cash distributions equal to or
less than $0.50 per Share).


 


4.2 Aggregation
of Shares. If after the date hereof, and subject to the provisions of Section 4.6 hereof, the number of issued and
outstanding Ordinary Shares is decreased by a consolidation, combination, reverse share split or reclassification of Ordinary
Shares or other similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification
or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such
decrease in issued and outstanding Ordinary Shares.


 


4.3 Adjustments
in Exercise Price.


 


4.3.1
Whenever the number of Ordinary Shares purchasable upon the exercise of the Warrants is adjusted, as provided in subsection
4.1.1 or Section 4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price
immediately prior to such adjustment by a fraction (x) the numerator of which shall be the number of Ordinary Shares purchasable
upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the number of
Ordinary Shares so purchasable immediately thereafter.


 


4.3.2
If (x) the Company issues additional Ordinary Shares or securities convertible into or exercisable or exchangeable for
Ordinary Shares, other than for the Forward Purchase Warrants and the Class A ordinary shares to be issued pursuant to the
Forward Purchase Agreement, for capital raising purposes in connection with the closing of the initial Business Combination
at an issue price or effective issue price of less than $9.20 (as adjusted for stock splits, stock dividends, rights
issuances, subdivisions, reorganizations, recapitalizations and the like) per Ordinary Share (with such issue price or
effective issue price to be determined in good faith by the Board and, in the case of any such issuance to the Sponsor or its
affiliates, without taking into account any shares of Founder Shares (as defined below) held by the Sponsor or such
affiliates, as applicable, prior to such issuance (the “Newly Issued Price”)), (y) the aggregate
gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for
funding the initial Business Combination on the date of the consummation of such initial Business Combination (net of
redemptions), and (z) the volume weighted average trading price of the Ordinary Shares during the 20 trading day period
starting on the trading day prior to the day on which the Company consummates the Business Combination (such price, the
“Market Value”) is below $9.20 per Ordinary Share (as adjusted for stock splits, stock dividends, rights
issuances, subdivisions, reorganizations, recapitalizations and the like), the Warrant Price shall be adjusted (to the
nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, the $18.00 per share
redemption trigger price described under Section 6.1 and Section 6.2 will be adjusted (to the nearest cent) to
be equal to 180% of the higher of the Market Value and the Newly Issued Price and the $10.00 per share redemption trigger
price described under Section 6.2 will be adjusted (to the nearest cent) to be equal to the higher of the Market Value
and the Newly Issued Price.

4.4
Replacement of Securities upon Reorganization, etc. In case of any reclassification or reorganization of the issued and
outstanding Ordinary Shares (other than a change under Section 4.1 or Section 4.2 hereof or that solely affects
the par value of such Ordinary Shares), or in the case of any merger or consolidation of the Company with or into another corporation
(other than a consolidation or merger in which the Company is the continuing corporation and that does not result in any reclassification
or reorganization of the issued and outstanding Ordinary Shares), or in the case of any sale or conveyance to another corporation
or entity of the assets or other property of the Company as an entirety or substantially as an entirety in connection with which
the Company is dissolved, the holders of the Warrants shall thereafter have the right to purchase and receive, upon the basis
and upon the terms and conditions specified in the Warrants and in lieu of the Ordinary Shares of the Company immediately theretofore
purchasable and receivable upon the exercise of the rights represented thereby, the kind and amount of shares or stock or other
securities or property (including cash) receivable upon such reclassification, reorganization, merger or consolidation, or upon
a dissolution following any such sale or transfer, that the holder of the Warrants would have received if such holder had exercised
his, her or its Warrant(s) immediately prior to such event (the “Alternative Issuance”); provided, however,
that (i) if the holders of the Ordinary Shares were entitled to exercise a right of election as to the kind or amount of securities,
cash or other assets receivable upon such consolidation or merger, then the kind and amount of securities, cash or other assets
constituting the Alternative Issuance for which each Warrant shall become exercisable shall be deemed to be the weighted average
of the kind and amount received per share by the holders of the Ordinary Shares in such consolidation or merger that affirmatively
make such election, and (ii) if a tender, exchange or redemption offer shall have been made to and accepted by the holders of
the Ordinary Shares (other than a tender, exchange or redemption offer made by the Company in connection with redemption rights
held by shareholders of the Company as provided for in the Company’s amended and restated memorandum and articles of association
or as a result of the repurchase of Ordinary Shares by the Company if a proposed initial Business Combination is presented to
the shareholders of the Company for approval) under circumstances in which, upon completion of such tender or exchange offer,
the maker thereof, together with members of any group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) of which
such maker is a part, and together with any affiliate or associate of such maker (within the meaning of Rule 12b-2 under the Exchange
Act) and any members of any such group of which any such affiliate or associate is a part, own beneficially (within the meaning
of Rule 13d-3 under the Exchange Act) more than 50% of the issued and outstanding Ordinary Shares, the holder of a Warrant shall
be entitled to receive as the Alternative Issuance, the highest amount of cash, securities or other property to which such holder
would actually have been entitled as a shareholder if such Warrant holder had exercised the Warrant prior to the expiration of
such tender or exchange offer, accepted such offer and all of the Ordinary Shares held by such holder had been purchased pursuant
to such tender or exchange offer, subject to adjustments (from and after the consummation of such tender or exchange offer) as
nearly equivalent as possible to the adjustments provided for in this Section 4; provided further that if less than 70%
of the consideration receivable by the holders of the Ordinary Shares in the applicable event is payable in the form of shares
in the successor entity that is listed for trading on a national securities exchange or is quoted in an established over-the-counter
market, or is to be so listed for trading or quoted immediately following such event, and if the Registered Holder properly exercises
the Warrant within thirty (30) days following the public disclosure of the consummation of such applicable event by the Company
pursuant to a Current Report on Form 8-K filed with the Commission, the Warrant Price shall be reduced by an amount (in dollars)
equal to the difference of (i) the Warrant Price in effect prior to such reduction minus (ii) (A) the Per Share Consideration
(as defined below) (but in no event less than zero) minus (B) the Black-Scholes Warrant Value (as defined below). The “Black-Scholes
Warrant Value” means the value of a Warrant immediately prior to the consummation of the applicable event based
on the Black-Scholes Warrant Model for a Capped American Call on Bloomberg Financial Markets (assuming zero dividends) (“Bloomberg”).
For purposes of calculating such amount, (i) Section 6 hereto shall be taken into account, (ii) the price of each Ordinary
Share shall be the volume weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading
day prior to the effective date of the applicable event, (iii) the assumed volatility shall be the 90 day volatility obtained
from the HVT function on Bloomberg determined as of the trading day immediately prior to the day of the announcement of the applicable
event and (iv) the assumed risk-free interest rate shall correspond to the U.S. Treasury rate for a period equal to the remaining
term of the Warrant. “Per Share Consideration” means (i) if the consideration paid to holders of the
Ordinary Shares consists exclusively of cash, the amount of such cash per Ordinary Share, and (ii) in all other cases, the volume
weighted average price of the Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the effective
date of the applicable event. If any reclassification or reorganization also results in a change in Ordinary Shares covered by
subsection 4.1.1, then such adjustment shall be made pursuant to subsection 4.1.1 or Sections 4.2, 4.3
and this Section 4.4. The provisions of this Section 4.4 shall similarly apply to successive reclassifications,
reorganizations, mergers or consolidations, sales or other transfers. In no event shall the Warrant Price be reduced to less than
the par value per share issuable upon exercise of such Warrant.

4.5 Notices
of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of Ordinary Shares issuable upon exercise of
a Warrant, the Company shall give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting
from such adjustment and the increase or decrease, if any, in the number of Ordinary Shares purchasable at such price upon the
exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is
based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3, or 4.4, the Company shall
give written notice of the occurrence of such event to each holder of a Warrant, at the last address set forth for such holder
in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice, or any defect therein,
shall not affect the legality or validity of such event.


 


4.6 No
Fractional Shares. Notwithstanding any provision contained in this Agreement to the contrary, the Company shall not issue fractional
shares upon the exercise of Warrants. If, by reason of any adjustment made pursuant to this Section 4, the holder of any
Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share, the Company shall, upon
such exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to such holder.


 


4.7 Form
of Warrant. The form of Warrant need not be changed because of any adjustment pursuant to this Section 4, and Warrants
issued after such adjustment may state the same Warrant Price and the same number of Ordinary Shares as is stated in the Warrants
initially issued pursuant to this Agreement; provided, however, that the Company may at any time in its sole discretion make any
change in the form of Warrant that the Company may deem appropriate and that does not affect the substance thereof, and any Warrant
thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant or otherwise, may be in the
form as so changed.


 


4.8 Other
Events. In case any event shall occur affecting the Company as to which none of the provisions of the preceding
subsections of this Section 4 are strictly applicable, but which would require an adjustment to the terms of the
Warrants in order to (i) avoid an adverse impact on the Warrants and (ii) effectuate the intent and purpose of this Section
4, then, in each such case, the Company shall appoint a firm of independent public accountants, investment banking or
other appraisal firm of recognized national standing, which shall give its opinion as to whether or not any adjustment to the
rights represented by the Warrants is necessary to effectuate the intent and purpose of this Section 4 and, if they
determine that an adjustment is necessary, the terms of such adjustment; provided, however, that under no circumstances shall
the Warrants be adjusted pursuant to this Section 4.8 as a result of any issuance of securities in connection with a
Business Combination. The Company shall adjust the terms of the Warrants in a manner that is consistent with any adjustment
recommended in such opinion.


 


4.9 No
Adjustment. For the avoidance of doubt, no adjustment shall be made to the terms of the Warrants solely as a result of an adjustment
to the conversion ratio of the Company’s Class B ordinary shares (the “Founder Shares”) into Ordinary Shares
or the conversion of the Founder Shares into Ordinary Shares, in each case, pursuant to the Company’s amended and restated
memorandum and articles of association.

		5.	Transfer and Exchange of Warrants.



 


5.1 Registration
of Transfer. The Warrant Agent shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant
Register, upon surrender of such Warrant for transfer, in the case of certificated Warrants, properly endorsed with signatures
properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such transfer, a new Warrant representing
an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the Warrant Agent. In the case
of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company from time to time upon
request.


 


5.2 Procedure
for Surrender of Warrants. Warrants may be surrendered to the Warrant Agent, together with a written request for exchange or
transfer, and thereupon the Warrant Agent shall issue in exchange therefor one or more new Warrants as requested by the Registered
Holder of the Warrants so surrendered, representing an equal aggregate number of Warrants; provided, however, that except as otherwise
provided herein or with respect to any Book-Entry Warrant, each Book-Entry Warrant may be transferred only in whole and only to
the Depositary, to another nominee of the Depositary, to a successor depository, or to a nominee of a successor depository; provided
further, however that in the event that a Warrant surrendered for transfer bears a restrictive legend (as in the case of the Private
Placement Warrants), the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant
Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new
Warrants must also bear a restrictive legend.


 


5.3 Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in
the issuance of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.


 


5.4 Service
Charges. No service charge shall be made for any exchange or registration of transfer of Warrants.


 


5.5 Warrant
Execution and Countersignature. The Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the
terms of this Agreement, the Warrants required to be issued pursuant to the provisions of this Section 5, and the Company,
whenever required by the Warrant Agent, shall supply the Warrant Agent with Warrants duly executed on behalf of the Company for
such purpose.


 


5.6 Transfer
of Warrants. Prior to the Detachment Date, the Public Warrants may be transferred or exchanged only together with the Unit
in which such Warrant is included, and only for the purpose of effecting, or in conjunction with, a transfer or exchange of such
Unit. Furthermore, each transfer of a Unit on the register relating to such Units shall operate also to transfer the Warrants included
in such Unit. Notwithstanding the foregoing, the provisions of this Section 5.6 shall have no effect on any transfer of
Warrants on and after the Detachment Date.


 


		6.	Redemption.



 


6.1
Redemption of Warrants When the Price per Ordinary Share Equals or Exceeds $18.00. Subject to Section 6.5 hereof,
not less than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period,
at the office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.3
below, at a Redemption Price of $0.01 per Warrant, provided that (a) the Reference Value equals or exceeds $18.00 per share (subject
to adjustment in compliance with Section 4 hereof) and (b) there is an effective registration statement covering the issuance
of the Ordinary Shares issuable upon exercise of the Warrants, and a current prospectus relating thereto, available throughout
the 30-day Redemption Period (as defined in Section 6.3 below).


 


6.2 Redemption
of Warrants When the Price per Ordinary Share Equals or Exceeds $10.00. Subject to Section 6.5 hereof, not less
than all of the outstanding Warrants may be redeemed, at the option of the Company, at any time commencing ninety (90) days
after the commencement of the Exercise Period and prior to the Expiration Date, at the office of the Warrant Agent, upon
notice to the Registered Holders of the Warrants, as described in Section 6.3 below, at a Redemption Price of $0.10
per Warrant, provided that (i) the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance
with Section 4 hereof), and (ii) if the Reference Value is less than $18.00 per share (subject to adjustment in
compliance with Section 4 hereof), the Private Placement Warrants are also concurrently called for redemption on the
same terms as the outstanding Public Warrants. During the 30-day Redemption Period in connection with a redemption pursuant
to this Section 6.2, Registered Holders of the Warrants may elect to exercise their Warrants on a “cashless
basis” pursuant to subsection 3.3.1 and receive a number of Ordinary Shares determined by reference to the table
below, based on the Redemption Date (calculated for purposes of the table as the period to expiration of the Warrants) and
the “Redemption Fair Market Value” (as such term is defined in this Section 6.2) (a
“Make-Whole Exercise”). Solely for purposes of this Section 6.2, the “Redemption
Fair Market Value” shall mean the volume weighted average price of the Ordinary Shares for the ten (10) trading
days immediately following the date on which notice of redemption pursuant to this Section 6.2 is sent to the
Registered Holders. In connection with any redemption pursuant to this Section 6.2, the Company shall provide the
Registered Holders with the Redemption Fair Market Value no later than one (1) Business Day after the ten (10) trading days
period described above ends.

The exact
Redemption Fair Market Value and Redemption Date may not be set forth in the table above, in which case, if the Redemption Fair
Market Value is between two values in the table or the Redemption Date is between two redemption dates in the table, the number
of Ordinary Shares to be issued for each Warrant exercised in a Make-Whole Exercise shall be determined by a straight-line interpolation
between the number of shares set forth for the higher and lower Redemption Fair Market Values and the earlier and later redemption
dates, as applicable, based on a 365- or 366-day year, as applicable.


 


The
share prices set forth in the column headings of the table above will be adjusted as of any date on which the number of shares
issuable upon exercise of a Warrant or the Warrant Price is adjusted as set forth under Section 4 hereof. If the number
of shares issuable upon exercise of a Warrant is adjusted, the adjusted share prices in the column headings will equal the share
prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the Warrant Price after such
adjustment and the denominator of which is the Warrant Price immediately prior to such adjustment. In such an event, the number
of shares in the table above shall be adjusted by multiplying such share amounts by a fraction, the numerator of which is the
number of shares deliverable upon exercise of a Warrant immediately prior to such adjustment and the denominator of which is the
number of shares deliverable upon exercise of a Warrant as so adjusted. If the Warrant Price is adjusted pursuant to Section
4.3.2, the adjusted share prices set forth in the column headings of the table above shall be multiplied by a fraction, the
numerator of which is the higher of the Market Value and the Newly Issued Price and the denominator of which is $10.00. In no
event shall the number of shares issued in connection with a Make-Whole Exercise exceed 0.361 Ordinary Shares per Warrant (subject
to adjustment).


 






    11


     


    

 


6.3 Date
Fixed for, and Notice of, Redemption; Redemption Price; Reference Value. In the event that the Company elects to redeem the
Warrants pursuant to Sections 6.1 or 6.2, the Company shall fix a date for the redemption (the “Redemption
Date”). Notice of redemption shall be mailed by first class mail, postage prepaid, by the Company not less than thirty
(30) days prior to the Redemption Date (the “30-day Redemption Period”) to the Registered Holders of
the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice mailed in the manner
herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received such notice.
As used in this Agreement, (a) “Redemption Price” shall mean the price per Warrant at which any Warrants
are redeemed pursuant to Sections 6.1 or 6.2 and (b) “Reference Value” shall mean the last
reported sales price of the Ordinary Shares for any twenty (20) trading days within the thirty (30) trading-day period ending on
the third trading day prior to the date on which notice of the redemption is given.


 


6.4 Exercise
After Notice of Redemption. The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with
Section 6.2 of this Agreement) at any time after notice of redemption shall have been given by the Company pursuant to Section
6.3 hereof and prior to the Redemption Date. On and after the Redemption Date, the record holder of the Warrants shall have
no further rights except to receive, upon surrender of the Warrants, the Redemption Price.


 


6.5 Exclusion
of Private Placement Warrants. The Company agrees that (a) the redemption rights provided in Section 6.1 hereof
shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants continue
to be held by the Sponsor or its Permitted Transferees and (b) if the Reference Value equals or exceeds $18.00 per share
(subject to adjustment in compliance with Section 4 hereof), the redemption rights provided in Section 6.2
hereof shall not apply to the Private Placement Warrants if at the time of the redemption such Private Placement Warrants
continue to be held by the Sponsor or its Permitted Transferees. However, once such Private Placement Warrants are
transferred (other than to Permitted Transferees in accordance with Section 2.6 hereof), the Company may redeem the
Private Placement Warrants pursuant to Section 6.1 or 6.2 hereof, provided that the criteria for redemption are
met, including the opportunity of the holder of such Private Placement Warrants to exercise the Private Placement Warrants
prior to redemption pursuant to Section 6.4 hereof. Private Placement Warrants that are transferred to persons other
than Permitted Transferees shall upon such transfer cease to be Private Placement Warrants and shall become Public Warrants
under this Agreement, including for purposes of Section 9.8 hereof.


 


		7.	Other Provisions Relating to Rights of Holders of
Warrants.



 


7.1 No
Rights as Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder of the
Company, including, without limitation, the right to receive dividends, or other distributions, exercise any preemptive rights
to vote or to consent or to receive notice as shareholders in respect of the meetings of shareholders or the election of directors
of the Company or any other matter.


 


7.2 Lost,
Stolen, Mutilated, or Destroyed Warrants. If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant
Agent may on such terms as to indemnity or otherwise as they may in their discretion impose (which shall, in the case of a mutilated
Warrant, include the surrender thereof), issue a new Warrant of like denomination, tenor, and date as the Warrant so lost, stolen,
mutilated, or destroyed. Any such new Warrant shall constitute a substitute contractual obligation of the Company, whether or not
the allegedly lost, stolen, mutilated, or destroyed Warrant shall be at any time enforceable by anyone.


 


7.3 Reservation
of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary
Shares that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.


 






    12


     


    

 


7.4 Registration
of Ordinary Shares; Cashless Exercise at Company’s Option.


 


7.4.1 Registration
of the Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than twenty (20) Business Days
after the closing of its initial Business Combination, it shall use its commercially reasonable efforts to file with the Commission
a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise of the Warrants.
The Company shall use its commercially reasonable efforts to cause the same to become effective within sixty (60) Business Days
following the closing of its initial Business Combination and to maintain the effectiveness of such registration statement, and
a current prospectus relating thereto, until the expiration or redemption of the Warrants in accordance with the provisions of
this Agreement. If any such registration statement has not been declared effective by the sixtieth (60th) Business Day following
the closing of the Business Combination, holders of the Warrants shall have the right, during the period beginning on the sixty-first
(61st) Business Day after the closing of the Business Combination and ending upon such registration statement being declared effective
by the Commission, and during any other period when the Company shall fail to have maintained an effective registration statement
covering the issuance of the Ordinary Shares issuable upon exercise of the Warrants, to exercise such Warrants on a “cashless
basis,” pursuant to Section 3.3.1, by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act or
another exemption) for that number of Ordinary Shares equal to the lesser of (A) the quotient obtained by dividing (x) the product
of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined
below) over the Warrant Price by (y) the Fair Market Value and (B) 0.361. Solely for purposes of this subsection 7.4.1,
“Fair Market Value” shall mean the volume weighted average price of the Ordinary Shares for the ten (10)
trading day period ending on the third trading day prior to the date that notice of exercise is received by the Warrant Agent from
the holder of such Warrants or its securities broker or intermediary. The date that notice of “cashless exercise” is
received by the Warrant Agent shall be conclusively determined by the Warrant Agent. In connection with the “cashless exercise”
of a Public Warrant, the Company shall, upon request, provide the Warrant Agent with an opinion of counsel for the Company (which
shall be an outside law firm with securities law experience) stating that (i) the exercise of the Warrants on a “cashless
basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities Act and (ii)
the Ordinary Shares issued upon such exercise shall be freely tradable under United States federal securities laws by anyone who
is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall not be
required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of doubt, unless and until
all of the Warrants have been exercised or have expired, the Company shall continue to be obligated to comply with its registration
obligations under the first three sentences of this subsection 7.4.1.


 


7.4.2 Cashless
Exercise at Company’s Option. If the Ordinary Shares are at the time of any exercise of a Public Warrant not listed
on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1)
of the Securities Act, the Company may, at its option, (i) require holders of Public Warrants who exercise Public Warrants to exercise
such Public Warrants on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act as described in
subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required to file or maintain
in effect a registration statement for the registration, under the Securities Act, of the Ordinary Shares issuable upon exercise
of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts to
register or qualify for sale the Ordinary Shares issuable upon exercise of the Public Warrant under applicable blue sky laws to
the extent an exemption is not available.


 


		8.	Concerning the Warrant Agent and Other Matters.



 


8.1 Payment
of Taxes. The Company shall from time to time promptly pay all taxes and charges that may be imposed upon the Company or the
Warrant Agent in respect of the issuance or delivery of Ordinary Shares upon the exercise of the Warrants, but the Company shall
not be obligated to pay any transfer taxes in respect of the Warrants or such Ordinary Shares.

8.2
Resignation, Consolidation, or Merger of Warrant Agent.


 


8.2.1
Appointment of Successor Warrant Agent. The Warrant Agent, or any successor to it hereafter appointed, may resign its duties
and be discharged from all further duties and liabilities hereunder after giving sixty (60) days’ notice in writing to the
Company. If the office of the Warrant Agent becomes vacant by resignation or incapacity to act or otherwise, the Company shall
appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the Company shall fail to make such appointment
within a period of thirty (30) days after it has been notified in writing of such resignation or incapacity by the Warrant Agent
or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection by the Company), then
the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for the appointment
of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company or by such
court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing
and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers
and subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be
vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect
as if originally named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary
or appropriate, the predecessor Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring
to such successor Warrant Agent all the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request
of any successor Warrant Agent the Company shall make, execute, acknowledge, and deliver any and all instruments in writing for
more fully and effectually vesting in and confirming to such successor Warrant Agent all such authority, powers, rights, immunities,
duties, and obligations.


 


8.2.2
Notice of Successor Warrant Agent. In the event a successor Warrant Agent shall be appointed, the Company shall give
notice thereof to the predecessor Warrant Agent and the Transfer Agent for the Ordinary Shares not later than the effective date
of any such appointment.


 


8.2.3
Merger or Consolidation of Warrant Agent. Any entity into which the Warrant Agent may be merged or with which
it may be consolidated or any entity resulting from any merger or consolidation to which the Warrant Agent shall be a party shall
be the successor Warrant Agent under this Agreement without any further act.


 


8.3 Fees
and Expenses of Warrant Agent.


 


8.3.1 Remuneration.
The Company agrees to pay the Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall,
pursuant to its obligations under this Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant
Agent may reasonably incur in the execution of its duties hereunder.


 


8.3.2 Further
Assurances. The Company agrees to perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged,
and delivered all such further and other acts, instruments, and assurances as may reasonably be required by the Warrant Agent for
the carrying out or performing of the provisions of this Agreement.


 


8.4 Liability
of Warrant Agent.


 


8.4.1
Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Warrant Agent
shall deem it necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering
any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed
to be conclusively proved and established by a statement signed by the Chairman of the Board, Chief Executive Officer, Chief Financial
Officer, President or Secretary and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action
taken or suffered in good faith by it pursuant to the provisions of this Agreement.


 


8.4.2
Indemnity. The Warrant Agent shall be liable hereunder only for its own gross negligence, willful misconduct, fraud or
bad faith. The Company agrees to indemnify the Warrant Agent and save it harmless against any and all liabilities, including judgments,
out-of-pocket costs and reasonable outside counsel fees, for anything done or omitted by the Warrant Agent in the execution of
this Agreement, except as a result of the Warrant Agent’s gross negligence, willful misconduct, fraud or bad faith.


 


8.4.3
Exclusions. The Warrant Agent shall have no responsibility with respect to the validity of this Agreement or with respect
to the validity or execution of any Warrant (except its countersignature thereof). The Warrant Agent shall not be responsible for
any breach by the Company of any covenant or condition contained in this Agreement or in any Warrant. The Warrant Agent shall not
be responsible to make any adjustments required under the provisions of Section 4 hereof or responsible for the manner,
method, or amount of any such adjustment or the ascertaining of the existence of facts that would require any such adjustment;
nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization or reservation of any
Ordinary Shares to be issued pursuant to this Agreement or any Warrant or as to whether any Ordinary Shares shall, when issued,
be valid and fully paid and nonassessable.


 






    14


     


    

 


8.5 Acceptance
of Agency. The Warrant Agent hereby accepts the agency established by this Agreement and agrees to perform the same upon the
terms and conditions herein set forth and among other things, shall account promptly to the Company with respect to Warrants exercised
and concurrently account for, and pay to the Company, all monies received by the Warrant Agent for the purchase of Ordinary Shares
through the exercise of the Warrants.


 


8.6 Waiver.
The Warrant Agent has no right of set-off or any other right, title, interest or claim of any kind (“Claim”)
in, or to any distribution of, the Trust Account (as defined in that certain Investment Management Trust Agreement, dated as of
the date hereof, by and between the Company and Continental Stock Transfer & Trust Company as trustee thereunder) and hereby
agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the Trust Account for any reason whatsoever.
The Warrant Agent hereby waives any and all Claims against the Trust Account and any and all rights to seek access to the Trust
Account.


 


		9.	Miscellaneous Provisions.

9.3 Applicable
Law and Exclusive Forum. The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed
in all respects by the laws of the State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding
or claim against it arising out of, or otherwise based on this Agreement shall be brought and enforced in the courts of the State
of New York or the United States District Court for the Southern District of New York, and irrevocably submits to such jurisdiction,
which jurisdiction shall be exclusive forum for any such action, proceeding or claim. The Company hereby waives any objection to
such exclusive jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions
of this paragraph will not apply to suits brought to enforce any liability or duty created by the Exchange Act or any other claim
for which the federal district courts of the United States of America are the sole and exclusive forum.


 


Any person
or entity purchasing or otherwise acquiring any interest in the Warrants shall be deemed to have notice of and to have consented
to the forum provisions in this Section 9.3. If any action, the subject matter of which is within the scope the forum provisions
above, is filed in a court other than a court located within the State of New York or the United States District Court for the
Southern District of New York (a “foreign action”) in the name of any warrant holder, such warrant holder shall be
deemed to have consented to: (x) the personal jurisdiction of the state and federal courts located within the State of New York
or the United States District Court for the Southern District of New York in connection with any action brought in any such court
to enforce the forum provisions (an “enforcement action”), and (y) having service of process made upon such warrant
holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign action as agent for such
warrant holder.


 


9.4 Persons
Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person, corporation
or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by
reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations,
promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their
successors and assigns and of the Registered Holders of the Warrants.


 


9.5 Examination
of the Warrant Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the Warrant
Agent in the United States of America, for inspection by the Registered Holder of any Warrant. The Warrant Agent may require any
such holder to submit such holder’s Warrant for inspection by the Warrant Agent.


 


9.6 Counterparts.
This 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.


 


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


 


9.8
Amendments. This Agreement may be amended by the parties hereto without the consent of any Registered Holder for the purpose
of (i) curing any ambiguity or to correct any mistake, including to conform the provisions hereof to the description of the terms
of the Warrants and this Agreement set forth in the Prospectus, or defective provision contained herein or (ii) adding or changing
any provisions with respect to matters or questions arising under this Agreement as the parties may deem necessary or desirable
and that the parties deem shall not adversely affect the rights of the Registered Holders under this Agreement. All other modifications
or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise Period and any amendment
to the terms of only the Private Placement Warrants, shall require the vote or written consent of the Registered Holders of 50%
of the then-outstanding Public Warrants and, solely with respect to any amendment to the terms of the Private Placement Warrants
or any provision of this Agreement with respect to the Private Placement Warrants, 50% of the then-outstanding Private Placement
Warrants, and, solely with respect to any amendment to the terms of the Forward Purchase Warrants or any provision of this Agreement
with respect to the Forward Purchase Warrants, 50% of the then-outstanding Forward Purchase Warrants. Notwithstanding the foregoing,
the Company may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1 and 3.2,
respectively, without the consent of the Registered Holders.

9.9 Severability.
This 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 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 Agreement a provision
as similar in terms to such invalid or unenforceable provision as may be possible and be valid and enforceable.

Warrant Certificate


 


This
Warrant Certificate certifies that               ,
or registered assigns, is the registered holder of              
warrant(s) (the “Warrants” and each, a “Warrant”) to purchase Class A
ordinary shares, $0.0001 par value (“Ordinary Shares”), of MSD Acquisition Corp., a Cayman Islands
exempted company (the “Company”). Each Warrant entitles the holder, upon exercise during the period
set forth in the Warrant Agreement referred to below, to receive from the Company that number of fully paid and nonassessable
Ordinary Shares as set forth below, at the exercise price (the “Exercise Price”) as determined
pursuant to the Warrant Agreement, payable in lawful money (or through “cashless exercise” as
provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and payment
of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth
herein and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the
meanings given to them in the Warrant Agreement.


 


Each whole
Warrant is initially exercisable for one fully paid and non-assessable Ordinary Share. Fractional shares shall not be issued upon
exercise of any Warrant. If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in an Ordinary
Share, the Company shall, upon exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to the
Warrant holder. The number of Ordinary Shares issuable upon exercise of the Warrants is subject to adjustment upon the occurrence
of certain events as set forth in the Warrant Agreement.


 


The initial
Exercise Price per one Ordinary Share for any Warrant is equal to $11.50 per share. The Exercise Price is subject to
adjustment upon the occurrence of certain events as set forth in the Warrant Agreement.


 


Subject
to the conditions set forth in the Warrant Agreement, the Warrants may be exercised only during the Exercise Period and to the
extent not exercised by the end of such Exercise Period, such Warrants shall become void. The Warrants may be redeemed, subject
to certain conditions, as set forth in the Warrant Agreement.


 


Reference
is hereby made to the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions
shall for all purposes have the same effect as though fully set forth at this place.


 


This Warrant
Certificate shall not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. This Warrant
Certificate shall be governed by and construed in accordance with the internal laws of the State of New York.

[Form of Warrant Certificate] 



 


[Reverse]


 


The Warrants evidenced by
this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive              Ordinary Shares
and are issued or to be issued pursuant to a Warrant Agreement dated as of February [●], 2021 (the “Warrant Agreement”),
duly executed and delivered by the Company to Continental Stock Transfer & Trust Company, a New York corporation, as warrant
agent (the “Warrant Agent”), which Warrant Agreement is hereby incorporated by reference in and made
a part of this instrument and is hereby referred to for a description of the rights, limitation of rights, obligations, duties
and immunities thereunder of the Warrant Agent, the Company and the holders (the words “holders” or “holder”
meaning the Registered Holders or Registered Holder, respectively) of the Warrants. A copy of the Warrant Agreement may be obtained
by the holder hereof upon written request to the Company. Defined terms used in this Warrant Certificate but not defined herein
shall have the meanings given to them in the Warrant Agreement.


 


Warrants
may be exercised at any time during the Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by
this Warrant Certificate may exercise them by surrendering this Warrant Certificate, with the form of Election to Purchase set
forth hereon properly completed and executed, together with payment of the Exercise Price as specified in the Warrant Agreement
(or through “cashless exercise” as provided for in the Warrant Agreement) at the principal corporate trust office
of the Warrant Agent. In the event that upon any exercise of Warrants evidenced hereby the number of Warrants exercised shall be
less than the total number of Warrants evidenced hereby, there shall be issued to the holder hereof or his, her or its assignee,
a new Warrant Certificate evidencing the number of Warrants not exercised.


 


Notwithstanding
anything else in this Warrant Certificate or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise
(i) a registration statement covering the issuance of the Ordinary Shares to be issued upon exercise is effective under the Securities
Act and (ii) a prospectus thereunder relating to the Ordinary Shares is current, except through “cashless exercise”
as provided for in the Warrant Agreement.


 


The Warrant
Agreement provides that upon the occurrence of certain events the number of Ordinary Shares issuable upon exercise of the Warrants
set forth on the face hereof may, subject to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof
would be entitled to receive a fractional interest in an Ordinary Share, the Company shall, upon exercise, round down to the nearest
whole number of Ordinary Shares to be issued to the holder of the Warrant.


 


Warrant
Certificates, when surrendered at the principal corporate trust office of the Warrant Agent by the Registered Holder thereof in
person or by legal representative or attorney duly authorized in writing, may be exchanged, in the manner and subject to the limitations
provided in the Warrant Agreement, but without payment of any service charge, for another Warrant Certificate or Warrant Certificates
of like tenor evidencing in the aggregate a like number of Warrants.


 


Upon due
presentation for registration of transfer of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate
or Warrant Certificates of like tenor and evidencing in the aggregate a like number of Warrants shall be issued to the transferee(s)
in exchange for this Warrant Certificate, subject to the limitations provided in the Warrant Agreement, without charge except for
any tax or other governmental charge imposed in connection therewith.


 


The Company
and the Warrant Agent may deem and treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding
any notation of ownership or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution
to the holder(s) hereof, and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice
to the contrary. Neither the Warrants nor this Warrant Certificate entitles any holder hereof to any rights of a shareholder of
the Company.

If said         number of Ordinary Shares is less than all of the Ordinary Shares purchasable

registered in the name of               , whose address is
               and that such Warrant Certificate be delivered

In
the event that the Warrant has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement

Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) or Section 6.2 of the Warrant
Agreement, as applicable.


 


In the
event that the Warrant is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection
3.3.1(b) of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in
accordance with subsection 3.3.1(b) of the Warrant Agreement.


 


In the
event that the Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement,
the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of
the Warrant Agreement.


 





In the event that
the Warrant may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of Ordinary
Shares that this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement
which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably
elects to exercise the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant
Agreement, to receive Ordinary Shares. If said number of shares is less than all of the Ordinary Shares purchasable hereunder
(after giving effect to the cashless exercise), the undersigned requests that a new Warrant Certificate representing the remaining
balance of such Ordinary Shares be registered in the name of               ,
whose address is                and that such Warrant Certificate
be delivered to               , whose address is               .
