 RE: Amended and Restated Securities Subscription Agreement 

Ladies and Gentlemen: 
 Pursuant to that certain
securities subscription agreement, dated as of March 2, 2021 (the “Original Agreement”), by and between Social Capital Suvretta Holdings Corp. IV, a Cayman Islands exempted company (the “Company”), and SCS
Sponsor IV LLC, a Cayman Islands limited liability company (the “Subscriber” or “you”), you subscribed for and purchased from the Company 5,750,000 Class B ordinary shares of the Company (the
“Shares”), of US$0.0001 par value per share (the “Class B Shares”), up to 750,000 of which are subject to forfeiture if the underwriter of the Company’s initial public offering of its
securities (“IPO”) do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company and the Subscriber now desire to amend and restate the Original Agreement in its entirety as set forth
herein. 
 For the purposes of this amended and restated securities subscription agreement (this “Agreement”), references
to “Ordinary Shares” are to, collectively, the Class B Shares and the Company’s Class A ordinary shares, of US$0.0001 par value per share (the “Class A Shares”). Upon certain terms
and conditions, the Class B Shares will automatically convert into Class A Shares on a one-for-one basis, subject to adjustment. Unless the context otherwise
requires, as used herein “Shares” shall be deemed to include any Class A Shares issued upon conversion of the Class B Shares comprising the Shares. 

The terms of the issuance of the Shares to the Subscriber, and the Company and the Subscriber’s agreements regarding such Shares, are as
follows: 
  

	1.	 Subscription and Surrender of Shares. 

 

	 	1.1	 Subscription for Shares. On March 2, 2021, for the sum of US$25,000, which the Company acknowledges
receiving in cash, the Company issued the Shares to the Subscriber, and the Subscriber subscribed for and purchased the Shares from the Company, 750,000 of which are subject to forfeiture, on the terms and subject to the conditions set forth in this
Agreement. Concurrently with the Subscriber’s execution of the Original Agreement, the Company registered the Shares in the name of the Subscriber on the register of members of the Company. All references in this Agreement to Shares being
forfeited shall take effect as surrenders for no consideration of such Shares as a matter of Cayman Islands law. 

  

	 	1.2	 Surrender of Class B Share. Upon the issue of the Shares, the Subscriber surrendered
to the Company for cancellation and for no consideration one (1) Class B Share standing in its name in the register of members of the Company. 

  

	2.	 Representations, Warranties and Agreements. 

 

	 	2.1	 Subscriber’s Representations, Warranties and Agreements. To induce the Company to issue the Shares
to the Subscriber, the Subscriber hereby represents and warrants to the Company and agrees with the Company as follows as of the date of the Original Agreement and the date of this Agreement: 

	 	2.1.1	 No Government Recommendation or Approval. The Subscriber understands that no federal or state agency has
passed upon or made any recommendation or endorsement of the offering of the Shares. 

  

	 	2.1.2	 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the
Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber
is a party or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the Subscriber is subject. 

 

	 	2.1.3	 Registration and Authority. The Subscriber is a Cayman Islands limited liability company, validly
formed, registered and in good standing under the laws of the Cayman Islands and possesses all requisite power and authority necessary to execute and deliver this Agreement and to carry out the transactions contemplated by this Agreement. Upon
execution and delivery by you, this Agreement is a legal, valid and binding agreement of the Subscriber, enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy,
insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity).

  

	 	2.1.4	 Experience, Financial Capability and Suitability. The Subscriber is: (i) sophisticated in financial
matters and able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the
Securities Act (as defined below) and therefore cannot be sold unless such transaction is registered under the Securities Act or an exemption from such registration is available. The Subscriber is capable of evaluating the merits and risks of its
investment in the Company and has the capacity to protect its own interests. The Subscriber must bear the economic risk of this investment until the Shares are sold pursuant to: (i) an effective registration statement under the Securities Act
or (ii) an exemption from registration available with respect to such sale. The Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete loss of the Subscriber’s investment in the Shares.

  

	 	2.1.5	 Access to Information; Independent Investigation. Prior to the execution of the Original Agreement, the
Subscriber had the opportunity to ask questions of and receive answers from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to
obtain additional information to verify the accuracy of all information so obtained. In determining whether to make an investment in the Shares, the Subscriber has relied solely on the Subscriber’s own knowledge and understanding of the Company
and its business based upon the Subscriber’s own due diligence investigation and the information furnished pursuant to this Section 2. The Subscriber understands that no person has been authorized to give any information or to make any
representations which were not furnished pursuant to this Section 2 and the Subscriber has not relied on any other representations or information in making its investment decision, whether written or oral, relating to the Company, its
operations and/or its prospects. 

  

	 	2.1.6	 Private Placement. The Subscriber is an “accredited investor” as such term is defined in Rule
501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being made in reliance on a private placement exemption applicable to “accredited
investors” within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under state law. 

  
 -2- 

	 	2.1.7	 Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes, for the
Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber is not entering into this Agreement as a result of any general solicitation
or general advertising within the meaning of Rule 502 of Regulation D under the Securities Act. 

  

	 	2.1.8	 Restrictions on Transfer; Shell Company. The Subscriber understands the Shares are being offered in a
transaction not involving a public offering within the meaning of the Securities Act. The Subscriber understands that the Shares will be “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act and the
Subscriber understands that any certificates or book-entries representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such
Shares may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. The Subscriber agrees that if any transfer of its Shares or any
interest therein is proposed to be made, as a condition precedent to any such transfer, the Subscriber may, at the Company’s option, be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or
an exemption, the Subscriber agrees not to resell the Shares. The Subscriber further acknowledges that because the Company is a shell company, Rule 144 under the Securities Act (“Rule 144”) may not be available to the Subscriber for
the resale of the Shares until at least one (1) year following consummation of the initial business combination of the Company (which may not occur), despite technical compliance with the requirements of Rule 144 and the release or waiver
of any contractual transfer restrictions. 

  

	 	2.1.9	 No Governmental Consents. No governmental, administrative or other third party consents or approvals are
required, necessary or appropriate on the part of the Subscriber in connection with the transactions contemplated by this Agreement. 

  

	2.2	 Company’s Representations, Warranties and Agreements. To induce the Subscriber to subscribe for the
Shares, the Company hereby represents and warrants to the Subscriber and agrees with the Subscriber as follows as of the date of the Original Agreement and the date of this Agreement: 

 

	 	2.2.1	 Incorporation and Corporate Power. The Company is a Cayman Islands exempted company and is qualified to
do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate
power and authority necessary to execute and deliver this Agreement and to carry out the transactions contemplated by this Agreement. Upon execution and delivery by the Company, this Agreement is a legal, valid and binding agreement of the Company,
enforceable against the Company in accordance with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement of creditors’ rights generally and
subject to general principles of equity (regardless of whether enforcement is sought in a proceeding at law or in equity). 

  

	 	2.2.2	 No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the
Company of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the Company’s Memorandum and Articles of Association, as amended to the date hereof (the “Memorandum and
Articles”), (ii) any agreement, indenture or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the
Company is subject. 

  
 -3- 

	 	2.2.3	 Title to Shares. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the
Memorandum and Articles, and registration in the register of members of the Company, the Shares will be duly and validly issued as fully paid and nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof and the
Memorandum and Articles, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and under the other agreements to which the
Shares may be subject, (b) transfer restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber. 

 

	 	2.2.4	 No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened
against or affecting the Company which: (i) seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity or legality of any transactions or seek to
recover damages or to obtain other relief in connection with any transactions. 

  

	 	2.2.5	 Authorization. The Class A Shares issuable upon conversion of the Shares have been duly authorized
and reserved for issuance upon such conversion. 

  

	3.	 Forfeiture of Shares. 

 

	 	3.1	 Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option granted to
the underwriter of the IPO is not exercised in full, the Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of Shares) shall, at the time such Over-allotment Option expires (or earlier if the underwriter of the IPO
waives its ability to exercise such Over-allotment Option), forfeit any and all rights to such number of Shares (up to an aggregate of 750,000 Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that
immediately following such forfeiture, the Subscriber (and any such transferees) will own an aggregate number of Shares equal to twenty-five percent (25%) of the number of Class A shares issued in the IPO (for the avoidance of doubt, excluding
any Class A shares issued pursuant to a private placement to occur concurrently with the closing of the IPO). Such forfeiture shall take effect as a surrender for no consideration as a matter of Cayman Islands law, and shall occur upon the
expiration of the Over-allotment Option. 

  

	 	3.2	 Termination of Rights as Shareholder. If any of the Shares are forfeited in accordance with this
Section 3, then after such time the Subscriber (or successor in interest), shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel such forfeited Shares.

  

	4.	 Waiver of Liquidation Distributions; Redemption Rights. In connection with the purchase of the Shares
pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s public
shareholders and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business
combination. For purposes of clarity, in the event the Subscriber purchases securities in the IPO or in the aftermarket, any Class A Shares so purchased shall be eligible to receive any liquidating distributions by the Company. However, in no
event will the Subscriber have the right to redeem any Ordinary Shares held by it for funds held in the Trust Account upon the successful completion of an initial business combination. 

 

	5.	 Restrictions on Transfer. 

 

	 	5.1	 Securities Law Restrictions. In addition to any restrictions to be contained in that certain agreement
(the “Letter Agreement”) to be entered into on or prior to the closing of the IPO by and among the Subscriber, the Company and the other parties thereto, the Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise
dispose of all or any part of the Shares unless, prior 

  
 -4- 

	 	
thereto (a) a registration statement on the appropriate form under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be
effective or (b) the Company shall have received, if requested by the Company, an opinion from counsel reasonably satisfactory to the Company, that such registration is not required because such transaction is exempt from registration under the
Securities Act and the rules promulgated by the Securities and Exchange Commission thereunder and with all applicable state securities laws. 

  

	 	5.2	 Lock-up. The Subscriber acknowledges that the Shares will be
subject to lock-up provisions (the “Lock-up”) contained in the Letter Agreement. Pursuant to the Letter Agreement, the Subscriber will agree (subject to
certain customary exceptions) not to sell, transfer, pledge, hypothecate or otherwise dispose of all or any part of the Shares until the earlier to occur of: (A) one year after the completion of the Company’s initial business combination
and (B) subsequent to the Company’s initial business combination, (x) if the last reported sale price of the Class A Shares equals or exceeds US$12.00 per share (as adjusted for share
sub-divisions, share capitalizations, rights issuances, subdivisions, reorganizations, recapitalizations and the like) for any twenty (20) trading days within any thirty (30)-trading day period commencing
at least one hundred and fifty (150) days after the Company’s initial business combination or (y) the date following the completion of the Company’s initial business combination on which the Company completes a liquidation,
merger, share exchange, reorganization or other similar transaction that results in all of the Company’s shareholders having the right to exchange their Class A Shares for cash, securities or other property. 

 

	 	5.3	 Restrictive Legends. Any certificates representing the Shares shall have endorsed thereon legends
substantially as follows: 

 “THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL (IF THE COMPANY SO REQUESTS), IS AVAILABLE.” 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED,
PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP PERIOD.” 
  

	 	5.4	 Additional Shares or Substituted Securities. In the event of the declaration of a share capitalization,
the declaration of an extraordinary dividend payable in a form other than Ordinary Shares, a spin-off, a share sub-division, an adjustment in conversion ratio, a
recapitalization or a similar transaction affecting the Company’s outstanding Ordinary Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction distributed
with respect to any Shares subject to this Section 5.4 or into which such Shares thereby become convertible shall immediately be subject to this Section 5.4 and Section 3. Appropriate adjustments to reflect the distribution of such
securities or property shall be made to the number and/or class of Ordinary Shares subject to this Section 5.4 and Section 3. 

  

	 	5.5	 Registration Rights. The Subscriber acknowledges that the Shares are being purchased pursuant to an
exemption from the registration requirements of the Securities Act and will become freely tradable, subject to the Lock-up, only after certain conditions are met or they are registered pursuant to a
registration rights agreement to be entered into with the Company prior to the closing of the IPO (the “Registration Rights Agreement”). 

  
 -5- 

	6.	 Voting and Tender of Shares. The Subscriber agrees to vote the Shares in favor of an initial business
combination that the Company negotiates and submits for approval to the Company’s shareholders and shall not seek redemption or repurchase with respect to any of the Shares in connection with an initial business combination or any amendment to
the Memorandum and Articles, as amended, prior to an initial business combination. Additionally, the Subscriber agrees not to tender any Shares in connection with a tender offer presented to the Company’s shareholders in connection with an
initial business combination negotiated by the Company. 

  

	7.	 Indemnification. Each party shall indemnify the other against any losses, costs or damages (including
reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement. 

 

	8.	 Other Agreements. 

 

	 	8.1	 Further Assurances. Each of the Subscriber and the Company agrees to execute such further instruments
and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. 

  

	 	8.2	 Notices. All notices, statements or other documents which are required or contemplated by this Agreement
shall be in writing and delivered (i) personally or sent by first class registered or certified mail, overnight courier service or electronic transmission to the address designated in writing or (ii) by electronic mail, to the electronic
mail address most recently provided to such party or such other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be deemed to have been given on the day of delivery, if
delivered personally, on the business day following receipt of written confirmation, if sent by electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after mailing if sent by mail.

  

	 	8.3	 Entire Agreement. This Agreement, together with the Letter Agreement and the Registration Rights
Agreement, each substantially in the form to be filed as an exhibit to the Company’s registration statement on Form S-1 relating to the IPO, embodies the entire agreement and understanding between the
Subscriber and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any
kind not expressly set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement. 

  

	 	8.4	 Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only
by written agreement executed by each party hereto. 

  

	 	8.5	 Waivers and Consents. The terms and provisions of this Agreement may be waived, or consent for the
departure therefrom granted, only by written instrument executed by the party entitled to the benefit of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute a waiver or consent with respect to any other
terms or provisions of this Agreement, whether or not similar. Each such waiver or consent shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver or consent.

  

	 	8.6	 Assignment. The rights and obligations under this Agreement may not be assigned by either party hereto
without the prior written consent of the other party. 

  

	 	8.7	 Benefit. All statements, representations, warranties, covenants and agreements in this Agreement shall
be binding on the parties hereto and shall inure to the benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties
hereto, and no person or entity shall be regarded as a third-party beneficiary of this Agreement. 

  
 -6- 

	 	8.8	 Governing Law. This Agreement and the rights and obligations of the parties hereunder shall be construed
in accordance with and governed by the laws of the State of New York, without giving effect to the conflict of laws principles thereof. 

  

	 	8.9	 Severability. In the event that any court of competent jurisdiction shall determine that any provision,
or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall remain
in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect. 

 

	 	8.10	 No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising any right,
power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement
by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The
election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving
such notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving such notice or demand to any other or further action in any circumstances without such notice
or demand. 

  

	 	8.11	 Survival of Representations and Warranties. All representations and warranties made by the parties
hereto and agreements contained in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby shall survive the execution and delivery hereof and any investigations made by or on behalf of the parties.

  

	 	8.12	 No Broker or Finder. Each of the parties hereto represents and warrants to the other that no broker,
finder or other financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and hold
harmless the other from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses
incurred in defending against any such claim. 

  

	 	8.13	 Headings and Captions. The headings and captions of the various sections of this Agreement are for
convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions hereof. 

  

	 	8.14	 Counterparts. This Agreement may be executed in one or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the
event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same
force and effect as if such signature page were an original thereof. 

  

	 	8.15	 Construction. The words “include,” “includes,” and “including” will be
deemed to be followed by “without limitation.” Pronouns in masculine, feminine and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless
the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder” and words of similar import refer to this Agreement as a whole and not to any particular section
unless expressly so limited. The parties hereto intend that each 

  
 -7- 

	 	
representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the
fact that such party hereto is in breach of the first representation, warranty, or covenant. 

  

	 	8.16	 Mutual Drafting. The parties hereto have participated jointly in the negotiation and drafting of this
Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because
of the authorship of any provision of this Agreement.

 NOW
THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement, intending legally to be bound,

Placement Shares at a price of $10.00 per Private Placement Share for an aggregate purchase price of $6,000,000 (the “Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company at

the Company, the Company, at its option, shall deliver a certificate evidencing the Private Placement Shares purchased by the Purchaser on such date duly registered in the Purchaser’s name to the Purchaser or effect such delivery in book-entry
form. 

 C. Terms of the Private Placement Shares. 

(i) The Private Placement Shares are substantially identical to the Shares to be offered in the Public Offering except that (a) the
Private Placement Shares will not, except in limited circumstances, be transferable, assignable or salable until 30 days after the Company has completed a merger, share exchange, asset acquisition, share repurchase, reorganization or similar
business combination with one or more businesses (the “Initial Business Combination”) (consistent with the terms of the letter agreement to be entered into by and among the Company, the Purchaser and the other
parties thereto in connection with the Public Offering (the “Letter Agreement”)), and (b) the Private Placement Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act
and will become freely tradable only after (i) the expiration of the lockup described above in clause (a) and (ii) they are registered pursuant to the Registration Rights Agreement (as defined below), or an exemption from registration is
available. 
 (ii) Prior to or on the date of the consummation of the Public Offering, the Company and the Purchaser shall enter into a

Section 2. Representations and Warranties of the Company. As a material inducement to the Purchaser to enter into this
Agreement and purchase the Private Placement Shares, the Company hereby represents and warrants to the Purchaser (which representations and warranties shall survive the Closing Date) that: 

A. Organization and Corporate Power. The Company is an exempted company duly incorporated, validly existing and in good standing under
the laws of the Cayman Islands and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material adverse effect on the financial condition, operating results or assets of the
Company. The Company possesses all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement. 

B. Authorization; No Breach. 

(i) The execution, delivery and performance of this Agreement have been duly authorized by the Company as of the Closing Date. This Agreement
constitutes the valid and binding obligation of the Company, enforceable in accordance with its terms, except that such enforcement may be subject to bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and other laws of general
applicability relating to or affecting creditors’ rights and to general equitable principles (whether considered in a proceeding in equity or law). 

(ii) The execution and delivery by the Company of this Agreement, the issuance and sale of the Private Placement Shares and the fulfillment of
and compliance with the terms hereof by the Company, do not and will not as of the Closing Date (a) conflict with or result in any violation or breach of the terms, conditions or provisions of, or constitute a default under, any law, statute,
rule, regulation, agreement, order, judgment or decree to which the Company is subject, (b) result in or give rise to the creation of any lien, security interest, charge or encumbrance upon the Company’s share capital or assets,

(iii) The Purchaser understands that the Private Placement Shares are being offered and will be sold to it in reliance on specific exemptions
from the registration requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and the Purchaser’s compliance with, the representations and warranties of the Purchaser
set forth herein in order to determine the availability of such exemptions and the eligibility of the Purchaser to acquire such Private Placement Shares.

meaning of Rule 502(c) of Regulation D under the Securities Act.

no United States federal or state agency or any other government or governmental agency has passed on or made any recommendation or endorsement of the Private Placement Shares or the fairness or suitability of the investment in the Private Placement
Shares by the Purchaser nor have such authorities passed upon or endorsed the merits of the offering of the Private Placement Shares. 

(vii) The Purchaser understands that: (a) the Private Placement Shares have not been and are not being registered under the Securities Act

Rights Agreement, neither the Company nor any other person is under any obligation to register the Private Placement Shares under the Securities Act or any state securities laws or to comply with the terms and conditions of any exemption thereunder;

transactions of Private Placement Shares after such Initial Business Combination. 
 (viii) The Purchaser has knowledge and experience in
financial and business matters, knowledge of the high degree of risk associated with investments in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment in the
Private Placement Shares and is able to bear the economic risk of an investment in the Private Placement Shares in the amount contemplated hereunder for an indefinite period of time. The Purchaser has adequate means of providing for its current
financial needs and contingencies and will have no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Private Placement Shares. The Purchaser can afford a complete loss of its investment in the
Private Placement Shares.
