RE: Securities Subscription Agreement  
 Ladies
and Gentlemen: 
 Aurora Technology Acquisition Corp., a Cayman Islands exempted company (the “Company”), is pleased to accept the offer
ATAC Sponsor LLC, a Delaware limited liability company (the “Subscriber” or “you”), has made to subscribe for 5,750,000 of the Company’s Class B ordinary shares (the “Shares”), US$0.0001
par value per share (the “Class B Shares”), up to 750,000 of which are subject to forfeiture by you if the underwriters of the Company’s initial public offering of its securities (“IPO”), if
any, do not fully exercise their over-allotment option (the “Over-allotment Option”). For the purposes of this agreement (this “Agreement”), references to “Ordinary Shares” are to, collectively, the
Class B Shares and the Company’s Class A ordinary shares, 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 on which the Company is willing to issue the Shares to the Subscriber, and the Company and the Subscriber’s agreements
regarding such Shares, are as follows: 
 1.    Subscription of Shares. For the sum of US$25,000, which the Company acknowledges
receiving in the form of a capital contribution, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby subscribes for the Shares from the Company, subject to forfeiture, on the terms and subject to the conditions set
forth in this Agreement. Concurrently with the Subscriber’s execution of this Agreement, the Company shall register the Shares in the name of the Subscriber on the register of members of the Company and, at its option, deliver to the Subscriber
a certificate registered in the Subscriber’s name representing the Shares (the “Original Certificate”), or effect such delivery in book-entry form. 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.    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: 

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.    Incorporation and Authority. The Subscriber is a Delaware limited liability
company, validly existing and in good standing under the laws of the State of Delaware and possesses all requisite power and authority necessary 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 is 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 this Agreement, the
Subscriber has 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 this investment, 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 paragraph. 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 

 2.1.6.    Private Placement. The Subscriber represents that it 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 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. 

2.1.7.    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 did not decide to enter into this Agreement as a result of any general
solicitation or general advertising within the meaning of Rule 502 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 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 may not be available to the Subscriber for the resale of the Shares until at least one 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: 

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 carry out the transactions contemplated by this Agreement. 
 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 

  
 3 

 
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. 
 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 seeks 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 Class B 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
underwriters 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 forfeit at the time such Over-allotment Option expires (or earlier if the underwriters of
the IPO waive their ability to exercise such Over-allotment Option) 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 number of Shares will equal 20% of the issued and outstanding Ordinary Shares immediately following the IPO (in each case, not including Class A Shares issuable upon exercise of any warrants). 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. 

3.3.    Share Certificates. In the event an adjustment to the Original Certificate, if any, is required pursuant to
this Section 3, then the Subscriber shall return such Original Certificate to the Company or its designated agent as soon as practicable upon its receipt of notice from the 

  
 4 

 
Company advising the Subscriber of such adjustment, following which a new certificate (the “New Certificate”), if any, shall be issued in such amount representing the adjusted
number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the Subscriber as soon as practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made in book-entry form or the
register of members of the Company (as applicable). 
 4.    Waiver of Liquidation Distributions; Redemption Rights. In
connection with the Shares purchased 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 into 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 letter
agreement (commonly known as an “Insider Letter”) dated 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 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 has 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 Insider Letter. Pursuant to the Insider Letter, 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 earliest to occur of: (a) six-months after the completion of the
Company’s initial business combination; and (b) subsequent to its initial business combination (x) if the last reported sale price of our Class A Shares equals or exceeds $12.00 per share (as adjusted for share sub-divisions, share dividends, rights issuances, consolidations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period
commencing at least 150 days after the Company’s initial business combination or (y) the date on which the Company completes a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction that results in
all of the Company’s public shareholders having the right to exchange their Shares for cash, securities or other property. 

  
 5 

 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 A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE
DISPOSED DURING THE TERM OF THE LOCKUP.” 
 5.4.    Additional Shares or Substituted Securities. In the
event of the declaration of a share dividend, the declaration of an extraordinary dividend payable in a form other than Ordinary Shares, a spin-off, a share split, 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 or into which such Shares thereby become convertible shall immediately be subject to this Section 5 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 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 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”). 
 6.    Other Agreements. 

6.1.    Further Assurances. The Subscriber 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. 
 6.2.    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 facsimile or electronic
transmission to the address designated in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated in writing by such party, or (iii) 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 facsimile or electronic transmission, one (1) business day after delivery to an overnight courier service or five (5) days after
mailing if sent by mail. 

  
 6 

 6.3.    Entire Agreement. This Agreement, together with that
certain Insider Letter to be entered into between the Subscriber and the Company and the Registration Rights Agreement, each substantially in the form to be filed as an exhibit to the Registration Statement, 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. 

6.4.    Modifications and Amendments. The terms and provisions of this Agreement may be modified or amended only by
written agreement executed by all parties hereto. 
 6.5.    Waivers and Consents. The terms and provisions of
this Agreement may be waived, or consent for the departure therefrom granted, only by written document executed by the party entitled to the benefits 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. 
 6.6.    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. 

6.7.    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.    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 New York applicable to contracts wholly performed within the borders of such state. 

6.9.    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. 

6.10.    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, 

  
 7 

 
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. 
 6.11.    Survival of Representations and Warranties. All
representations and warranties made by the parties hereto 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. 
 6.12.    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 save the other harmless 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. 
 6.13.    Headings and Captions. The headings and
captions of the various subdivisions 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. 

6.14.    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. 
 6.15.    Construction. 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. 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 subdivision unless expressly so limited.
The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or 

  
 8 

 
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. 

6.16.    Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and each provision
hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed for or against any party hereto. 

6.17.    Surrender of Class A Ordinary Share. The Subscriber hereby surrenders to the Company
for cancellation and for nil consideration one Class B ordinary share of a par value US$0.0001 standing in its name in the register of members of the Company. 

6.18.    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 with respect to any of the Shares in connection with an initial business combination or any amendment to the
Company’s Memorandum and Articles of Association, 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 loss, cost 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.

issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, up to 525,000 Private Placement Warrants (or, to the extent the option to purchase additional units is not exercised in full, a lesser number of Private Placement
Warrants in proportion to portion of the option that is exercised) at a price of $1.00 per warrant for an aggregate purchase price of up to $525,000 (the “Option Purchase Price”). The Purchaser shall pay the Option Purchase
Price in accordance with the Company’s wire instruction by wire transfer of immediately available funds to the Trust Account, at least one (1) business day prior to the Option Closing Date. On the Option Closing Date, subject to the

issuable upon exercise of the Private Placement Warrants) may be subject to certain transfer restrictions contained in the letter agreement by and among the Company, the Purchaser and any other parties thereto, as amended from time to time,
including that any permitted transferees must enter into a written agreement with the Company agreeing to be bound by the transfer restrictions contained in such letter agreement, and (3) the Private Placement Warrants shall not be redeemable
by the Company. 
 (iii) On the IPO Closing Date, the Company and the Purchaser shall enter into a Registration Rights Agreement (the
“Registration Rights Agreement”) pursuant to which the Company will grant certain registration rights to the Purchaser relating to the Private Placement Warrants and the Class A Ordinary Shares underlying the Private
Placement Warrants. 
 Section 2. Representations and Warranties of the Company. As a material inducement to the Purchaser to

Section 3. Representations and Warranties of the Purchaser. As a material inducement to the Company to enter into this Agreement and
issue and sell the Private Placement Warrants to the Purchaser, the Purchaser hereby represents and warrants to the Company (which representations and warranties shall survive each Closing Date) that: 

A. Organization and Requisite Authority. The Purchaser is duly organized, validly existing and in good standing under the laws of the
State of Delaware and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. 

B. Authorization; No Breach. 

(i) This Agreement constitutes a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, 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 Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by
the Purchaser does not and shall not as of each Closing Date (a) conflict with or result in a breach by the Purchaser of the terms, conditions or provisions of, (b) constitute a default under, (c) result in the creation of any lien,

law, statute, rule or regulation to which the Purchaser is subject, or any agreement, instrument, order, judgment or decree to which the Purchaser is subject, except for any filings required after the date hereof under federal or state securities
laws. 

 C. Investment Representations. 

(i) The Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Class A Ordinary
Shares issuable upon such exercise (collectively, the “Securities”) for its own account, for investment purposes only and not with a view towards, or for resale in connection with, any public sale or distribution thereof.

 (ii) The Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D, and the
Purchaser has not experienced a disqualifying event as enumerated pursuant to Rule 506(d) of Regulation D under the Securities Act. 
 (iii)
The Purchaser understands that the Securities 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
Securities. 
 (iv) The Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising
within the meaning of Rule 502(c) under the Securities Act. 
 (v) The Purchaser has been furnished with all materials relating to the
business, finances and operations of the Company and materials relating to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to ask questions of the executive officers
and directors of the Company. The Purchaser understands that its investment in the Securities involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed investment
decision with respect to the acquisition of the Securities. 
 (vi) The Purchaser understands that 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 Securities or the fairness or suitability of the investment in the Securities by the Purchaser nor have such authorities passed upon or
endorsed the merits of the offering of the Securities. 
 (vii) The Purchaser understands that: (a) the Securities have not been and
are not being registered under the Securities Act or any state securities laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance on an exemption therefrom;
and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder. In this regard, the Purchaser understands that the SEC has taken the position that promoters or affiliates of a blank check company and their transferees, both before and after an initial
Business Combination, are deemed to be “underwriters” under the Securities Act when reselling the securities of a blank check company. Based on that position, Rule 144 adopted pursuant to the Securities Act would not be
available for resale transactions of the Securities despite technical compliance with the requirements of such Rule, and the Securities can be resold only through a registered offering or in reliance upon another exemption from the registration
requirements of the Securities Act. 

 (viii) The Purchaser has such 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 Securities and is able to bear the
economic risk of an investment in the Securities 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 Securities. The Purchaser can afford a complete loss of its investments in the Securities. 

(ix) The Purchaser understands that the Private Placement Warrants shall bear the legend substantially in the form set forth in the Warrant
Agreement.

the Private Placement Warrants are subject to the fulfillment, on or before each Closing Date, of each of the following conditions:

 A.
Successors and Assigns. Except as otherwise expressly provided herein, all covenants and agreements contained in this Agreement by or on behalf of any of the parties hereto shall bind and inure to the benefit of the respective successors of

 B. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity,
without invalidating the remainder of this Agreement.

New York and for all purposes shall be construed in accordance with the internal laws of the State of New York, without giving effect to conflicts of law principles that would result in the application of the laws of another jurisdiction.

particular provision, except by a written instrument executed by the parties hereto.
