 Exhibit 4.1 

Executed 
 WARRANT
AGREEMENT 
 between 

SUPERNOVA PARTNERS ACQUISITION COMPANY III, LTD. 

and 
 AMERICAN STOCK
TRANSFER & TRUST COMPANY, LLC 
 Dated March 22, 2021 

THIS WARRANT AGREEMENT (this “Agreement”), dated March 22, 2021, is by and between Supernova Partners
Acquisition Company III, Ltd., a Cayman Islands exempted company (the “Company”), and American Stock Transfer & Trust Company, LLC, a New York corporation, as warrant agent (in such capacity, the
“Warrant Agent”). 
 WHEREAS, it is proposed that the Company enter into that certain Private Placement
Warrants Purchase Agreement, with Supernova Partners III LLC, a Cayman Islands limited liability company (the “Sponsor”), pursuant to which the Sponsor will purchase an aggregate of 3,500,000 warrants (or up to
3,875,000 warrants if the underwriters in the Offering (defined below) exercise their Overallotment Option (as defined below) in full) simultaneously with the closing of the Offering (and the closing of the Over-allotment Option, if applicable),
bearing the legend set forth in Exhibit B hereto (the “Private Placement Warrants”) at a purchase price of $2.00 per Private Placement Warrant. Each Private Placement Warrant entitles the holder thereof to
purchase one Ordinary Share (as defined below) at a price of $11.50 per share, subject to adjustment as described herein; and 
 WHEREAS, in
order to finance the Company’s transaction costs in connection with an intended initial merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination, involving the Company and one or more businesses
(a “Business Combination”), the Sponsor or an affiliate of the Sponsor or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as the Company may require, of which
up to $1,500,000 of such loans may be convertible into up to an additional 750,000 Private Placement Warrants at a price of $2.00 per Private Placement Warrant; and 

WHEREAS, the Company is engaged in an initial public offering (the “Offering”) of units of the Company’s
equity securities, each such unit comprised of one Ordinary Share and a fraction of a Public Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and deliver up to 5,750,000
redeemable warrants (including up to 750,000 redeemable warrants to the extent the Over-allotment Option is exercised) to public investors in the Offering (the “Public Warrants” and, together with the Private Placement
Warrants, the “Warrants”). 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. Only whole Warrants are exercisable. A holder of the Warrants will not be able to exercise any fraction of a Warrant; and 

WHEREAS, the Company has filed with the Securities and Exchange Commission (the “Commission”) a registration
statement on Form S-1, File No. 333-253235, 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; and 

 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; and 

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 or
Co-Chairman of the Board, Chief Executive Officer, President, Chief Financial Officer, Chief Operating 

  
 2 

 
Officer, General Counsel, 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. 

2.3.1.     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. 
 2.4.     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 J.P. Morgan Securities LLC and Jefferies 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 (i) 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 underwriters of their 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 (ii) a second or amended Current Report on Form 8-K to provide updated financial information to reflect the exercise of the
underwriters’ Over-allotment Option, if the Over-allotment Option is exercised following the initial filing of such 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 a fraction 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. 

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(c) 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; provided, however, that in the case of (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 direct or indirect members or partners of the Sponsor or their affiliates, or any employees of such affiliates; 

  
 3 

 (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 the Company’s
Business Combination at prices no greater than the price at which the founder shares, Private Placement Warrants or Ordinary Shares, as applicable, were originally purchased; 

(f)     by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the
Sponsor; 
 (g)     to the Company for no value for cancellation in connection with the consummation of
our initial Business Combination; 
 (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 (i), 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. 

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 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 three Business 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. 

  
 4 

 3.2.     Duration of Warrants. A Warrant may be exercised only
during the period (the “Exercise Period”) (A) commencing on the date that is thirty (30) days after the first date on which the Company completes a Business Combination 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 amended from time to time, 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, 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 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) 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)     [Reserved]; 

(c)     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 the quotient obtained by dividing (x) the product of the number of Ordinary Shares underlying the Warrants,
multiplied by the excess of the “Sponsor Fair Market Value” (as defined in this subsection 3.3.1(c)) less the Warrant Price by (y) the Sponsor Fair Market Value. Solely for purposes of this subsection
3.3.1(c), the “Sponsor 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; 

  
 5 

 (d)     as provided in Section 6.2 hereof
with respect to a Make-Whole Exercise; or 
 (e)     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 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 and the Amended and Restated Memorandum and Articles of Association of the Company, and upon registration in the Register of Members of the Company, shall be validly issued, fully
paid and nonassessable. 
 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. 

  
 6 

 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 9.8% (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 American 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 sub-division of
Ordinary Shares or other similar event, then, on the effective date of such share capitalization, sub-division 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 capitalization 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 the Ordinary Shares) multiplied by 

  
 7 

 
(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.

 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 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 public
shares if it 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, (e) 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 or
(f) 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 to the extent it does not
exceed $0.50 (which amount shall be 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). 
 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.
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 

  
 8 

 
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. 

4.4.     Raising of the Capital in Connection with the Initial Business Combination. If (x) the Company issues
additional Ordinary Shares or equity-linked securities for capital raising purposes in connection with the closing of its initial Business Combination at an issue price or effective issue price of less than $9.20 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 Class B ordinary shares, par value $0.0001 per share, of the
Company 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 the funding of the Company’s initial Business Combination on the date of the completion of the Company’s initial Business Combination (net of redemptions), and (z) the volume-weighted average trading
price of Ordinary Shares during the twenty (20) trading day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the “Market Value”) is below
$9.20 per share, 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 in Section 6.1 and
Section 6.2 shall 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 in Section 6.2 shall be adjusted
(to the nearest cent) to be equal to the higher of the Market Value and the Newly Issued Price. 
 4.5.    
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 

  
 9 

 
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 of this Agreement 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. 

4.6.     Notices of Changes in Warrant. Upon every adjustment of the Warrant Price or the number of 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 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,
4.4 or 4.5, 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. 

4.7.     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. 

  
 10 

 4.8.     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 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. 

4.9.     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. The Company
shall adjust the terms of the Warrants in a manner that is consistent with any adjustment recommended in such opinion. 

4.10.     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 Class B ordinary shares (the “Class B Ordinary Shares”) into Ordinary Shares or the conversion of the shares of
Class B Ordinary 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, 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. 

  
 11 

 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 for Cash. 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 for $0.10 or for Ordinary Shares. 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 $0.10 per Warrant, provided that the Reference Value equals or exceeds $10.00 per share (subject to adjustment in compliance with Section 4 hereof).
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 ending on the third trading day prior to 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 day 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 shall be adjusted as of any date on which the number of shares issuable upon exercise of a Warrant or the Exercise Price is adjusted pursuant to Section 4 hereof. If the number of shares
issuable upon exercise of a Warrant is adjusted pursuant to Section 4 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment, multiplied 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. The number of shares in the table
above shall be adjusted in the same manner and at the same time as the number of shares issuable upon exercise of a Warrant. If the Exercise Price of a warrant is adjusted, (a) in the case of an adjustment pursuant to Section 4.4
hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment 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 and (b) in the case of an adjustment pursuant to Section 4.1.2 hereof, the adjusted share prices in the column headings shall equal the share prices immediately prior to such adjustment less the
decrease in the Exercise Price pursuant to such Exercise Price adjustment. 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) 

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 

  
 13 

 
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 on the
trading day prior to the date on which we send the notice of redemption to the Registered Holder. 
 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 the redemption rights
provided in Section 6.1 and 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. 

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 

  
 14 

 
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,” 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) less
the Warrant Price by (y) the Fair Market Value and (B) 0.361 per Warrant. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume-weighted average price of the Ordinary Shares as
reported during the ten (10) trading day period ending on the 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

 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 

  
 16 

 
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
Chief Executive Officer, the President, the Chief Financial Officer, Chief Operating Officer, the General Counsel, the Secretary or the Chairman or Co-Chairman of the Board of the Company 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 and the Amended and Restated Memorandum and Articles of Association of the Company, and upon registration in the Register of Members of the
Company, or as to whether any Ordinary Shares shall, when issued, be valid and fully paid and nonassessable. 
 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 American Stock Transfer & Trust Company, LLC 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. 

9.1.     Successors. All the covenants and provisions of this Agreement by or for the benefit of the Company or the
Warrant Agent shall bind and inure to the benefit of their respective successors and assigns. 
 9.2.

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 relating in any way to 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 

  
 18 

 
“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 (i) for the purpose of (x) 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, (y) amending the definition of “Ordinary Cash Dividend” as contemplated by and in accordance with the second sentence of subsection 4.1.2 or
(z) 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 and (ii) to provide for the delivery of Alternative Issuance pursuant to Section 4.5. 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. 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.

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

(the “Warrant Agreement”), duly executed and delivered by the Company to American Stock Transfer & Trust Company, LLC, 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. 

  
 A-3 

 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.

Agreement.

initial Business Combination, then in connection with such proposed initial Business Combination, it, she or he, as applicable, shall vote all Founder Shares and any Public Shares held by it, her or him, as applicable, in favor of such proposed
initial Business Combination (including any proposals recommended by the Board in connection with such Business Combination) and not redeem any Public Shares held by it, her or him, as applicable, in connection with such shareholder approval.

  

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

 

	 	(a)	 The Sponsor and each Insider hereby agree, with respect to itself, herself or himself, that in the event that
the Company fails to consummate its initial Business Combination within the time period set forth in the Charter, the Sponsor and each Insider shall take all reasonable steps to cause the Company to (i) cease all operations except for the
purpose of winding up; (ii) as promptly as reasonably possible but not more than 10 business days thereafter, redeem 100% of the Public Shares, at a per-share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously release to the Company to pay 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 each case 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 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 

  
 3 

	 	
result of any liquidation of the Company with respect to the Founder Shares held by it, her or him, if any. The Sponsor and each of the Insiders hereby further waive, with respect to any Founder
Shares and Public Shares held by it, her or him, as applicable, any redemption rights it, she or he may have in connection with the consummation of a Business Combination, including, without limitation, any such rights available in the context of a
shareholder vote to approve such Business Combination or a shareholder vote to approve an amendment to the Charter (i) that would modify the substance or timing of the Company’s obligation to provide holders of the Public Shares the right
to have their shares redeemed in connection with an initial Business Combination or to redeem 100% of the Public Shares if the Company has not consummated an initial Business Combination within the time period set forth in the Charter or
(ii) with respect to any provision relating to the rights of holders of Public Shares (although the Sponsor and the Insiders shall be entitled to liquidation rights with respect to any Public Shares they hold if the Company fails to consummate
a Business Combination within the required time period set forth in the Charter). 

  

	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 Warrants or
Ordinary Shares underlying such warrants until 30 days after the completion of an initial Business Combination. 

  

	 	(c)	 Notwithstanding the provisions set forth in paragraphs 5(a) and (b), Transfers of the Founder
Shares, Private Placement Warrants and Ordinary Shares underlying the Private Placement Warrants are permitted (a) to the Company’s officers or directors, any 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, 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 

  
 4 

	 	
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, Private Placement Warrants or Ordinary Shares, as applicable, were originally purchased;
(f) by virtue of the Sponsor’s organizational documents upon liquidation or dissolution of the Sponsor; (g) to the Company for no value for cancellation in connection with the consummation of an initial Business Combination,
(h) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (i) in the event of completion of a liquidation, merger, share exchange or other similar transaction which results in all of the
Company’s Public Shareholders having the right to exchange their Ordinary Shares for cash, securities or other property subsequent to the completion of an initial Business Combination; provided, however, that in the case of
clauses (a) through (i) these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions. 

  

	 	(d)	 During the period commencing on the date of the Prospectus and ending 180 days after such date, the Sponsor and
each Insider shall not, without the prior written consent of the Representatives, Transfer any Units, Ordinary Shares, Warrants or any other securities convertible into, or exercisable or exchangeable for, Ordinary Shares held by it, her or him, as
applicable, subject to certain exceptions enumerated in Section 4(h) of the Underwriting Agreement. 

  

	6.	 Remedies. The Sponsor and each of the Insiders hereby agree and acknowledge that (i) each of the
Underwriters and the Company would be irreparably injured in the event of a breach by the Sponsor or such Insider of its, her or his obligations, as applicable under paragraphs 3, 4, 5, 6, 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. 

  
 5 

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

 

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

  
 6 

	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.
