 Exhibit 4.2 

RIGHTS AGREEMENT 
 This
Rights Agreement (this “Agreement”) is made as of February 7, 2022 between Aurora Technology Acquisition Corp., a Cayman Islands exempted company, with offices at 4 Embarcadero Center, Suite 1449, San Francisco, California 94105 (the
“Company”), and Continental Stock Transfer & Trust Company, a New York corporation, with offices at One State Street, 30th Floor, New York, New York 10004 (“Rights Agent”). 

WHEREAS, the Company is engaged in a public offering (“Public Offering”) of Units and, in connection therewith, will issue and
deliver up to 20,000,000 Rights (or up to 23,000,000 Rights if the underwriters’ over-allotment option is exercised in full) to the public investors; and 

WHEREAS, the Company has filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1, File
No. 333-261753 (“Registration Statement”), and related prospectus (“Prospectus”) for the registration, under the Securities Act of 1933, as amended (“Act”), of, among other securities, the Rights and the
Class A Ordinary Shares issuable to the holders of the Rights; and 
 WHEREAS, the Company desires the Rights Agent to act on behalf of
the Company, and the Rights Agent is willing to so act, in connection with the issuance, registration, transfer and exchange of the Rights; and 

WHEREAS, the Company desires to provide for the form and provisions of the Rights, the terms upon which they shall be issued, and the
respective rights, limitation of rights, and immunities of the Company, the Rights Agent, and the holders of the Rights; and 
 WHEREAS, all
acts and things have been done and performed which are necessary to make the Rights, when executed on behalf of the Company and countersigned by or on behalf of the Rights Agent, 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 Rights Agent. The Company hereby appoints the Rights Agent to act as agent for the Company for
the Rights, and the Rights Agent hereby accepts such appointment and agrees to perform the same in accordance with the terms and conditions set forth in this Agreement. 

2. Rights. 
 2.1. Form of Right.
Each Right shall be issued in registered form only, shall be in substantially the form of Exhibit A hereto, the provisions of which are incorporated herein and shall be signed by, or bear the facsimile signature of, the Chairman of the Board or
Chief Executive Officer and the Secretary of the Company and shall bear a facsimile of the Company’s seal. In the event the person whose facsimile signature has been placed upon any Right shall have ceased to serve in the capacity in which such
person signed the Right before such Right 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. 

2.2. Effect of Countersignature. Unless and until countersigned by the Rights Agent pursuant to this Agreement, a Right shall be
invalid and of no effect and may not be exchanged for Class A Ordinary Shares. 
 2.3. Registration. 

 2.3.1 Right Register. The Rights Agent shall maintain books (“Right
Register”) for the registration of original issuance and the registration of transfer of the Rights. Upon the initial issuance of the Rights, the Rights Agent shall issue and register the Rights in the names of the respective holders thereof in
such denominations and otherwise in accordance with instructions delivered to the Rights Agent by the Company. 
 2.3.2 Registered
Holder. Prior to due presentment for registration of transfer of any Right, the Company and the Rights Agent may deem and treat the person in whose name such Right shall be registered upon the Right Register (“registered holder”) as
the absolute owner of such Right and of each Right represented thereby (notwithstanding any notation of ownership or other writing on the Right Certificate made by anyone other than the Company or the Rights Agent), for the purpose of the exchange
thereof, and for all other purposes, and neither the Company nor the Rights Agent shall be affected by any notice to the contrary. 
 2.4.
Detachability of Rights. The securities comprising the Units, including the Rights, will not be separately transferable until the earlier to occur of: (i) the 52nd day following the date of the Prospectus or (ii) the announcement by
Maxim Group LLC, as representative of the underwriters in the Public Offering, of its intention to allow separate earlier trading, except that in no event will the securities comprising the Units be separately tradeable until the Company files a
Current Report on Form 8-K with the SEC which includes an audited balance sheet reflecting the receipt by the Company of the gross proceeds of the Public Offering including the proceeds received by the Company from the exercise of the over-allotment
option, if the over-allotment option is exercised by the date thereof and the Company issues a press release and files a Current Report on Form 8-K with the SEC announcing when such separate trading shall begin. 

3. Terms and Exchange of Rights 
 3.1.
Rights. Each Right shall entitle the holder thereof to receive one-tenth of one Class A Ordinary Share upon the happening of an Exchange Event (defined below). No additional consideration shall be paid by a holder of Rights in order to
receive his, her or its Class A Ordinary Shares upon an Exchange Event as the purchase price for such Class A Ordinary Shares has been included in the purchase price for the Units. In no event will the Company be required to net cash
settle the Rights or issue fractional Ordinary Shares. 
 3.2. Exchange Event. An “Exchange Event” shall occur upon the
Company’s consummation of an initial Business Combination (as defined in the Company’s Amended and Restated Memorandum and Articles of Association). 

3.3. Exchange of Rights. 

3.3.1 Issuance of Ordinary Shares. As soon as practicable upon the occurrence of an Exchange Event, the Company shall direct holders of
the Rights to return their Rights Certificates to the Rights Agent. Upon receipt of a valid Rights Certificate, the Company shall issue to the registered holder of such Right(s) the number of full 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 and issue to such registered holder(s) a certificate or book-entry position for the such shares. Notwithstanding the foregoing, or any provision contained in this Agreement to the
contrary, in no event will the Company be required to net cash settle the Rights. The Company shall not issue fractional shares upon exchange of Rights. In the event that any holder would otherwise be entitled to any fractional share upon exchange
of Rights, at the time of an Exchange Event, the Company will instruct the Right Agent how any such entitlement will be addressed. To the fullest extent permitted by the Company’s Amended and Restated Memorandum and Articles of Association the
Company reserves the right to deal with any such fractional entitlement at the relevant time in any manner permitted by the Act and the Amended and Restated Memorandum and Articles, which would include the rounding down of any entitlement to receive
Ordinary Shares to the nearest whole share (and in effect extinguishing any fractional entitlement), or the holder being entitled to hold any remaining fractional entitlement (without any share being issued) and to aggregate the same with any future
fractional entitlement to receive shares in the Company until the holder is entitled to receive a whole number. Any rounding down and extinguishment may be done with or without any in lieu cash payment or other compensation being made to the holder
of the relevant Rights, such that value received on exchange of the Rights may be considered less than the value that the holder would otherwise expect to receive. 

  
 2 

 3.3.2 Valid Issuance. All Ordinary Shares issued upon an Exchange Event 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. 

3.3.3 Date of Issuance. Each person in whose name any such certificate or book-entry position for Ordinary Shares is issued shall for
all purposes be deemed to have become the holder of record of such shares on the date of the Exchange Event, irrespective of the date of delivery of such certificate or entry of position. 

3.3.4 Company Not Surviving Following Exchange Event. Upon an Exchange Event in which the Company does not continue as the publicly
held reporting entity, the definitive agreement will provide for the holders of Rights to receive the same per share consideration the holders of the Ordinary Shares will receive in such transaction, for the number of shares such holder is entitled
to pursuant to Section 3.3.1 above. If the Company does not continue as the publicly held reporting entity upon an Exchange Event, each holder of a Right will be required to affirmatively convert his/her or its rights in order to receive the
1/10 share underlying each right (without paying any additional consideration) upon consummation of the Exchange Event. In such a case, each holder of a Right will be required to indicate his, her or its election to convert the Rights into
underlying shares as well as to return the original certificates evidencing the Rights to the Company. 
 3.4. Duration of Rights. If
an Exchange Event does not occur within the time period set forth in the Company’s Amended and Restated Memorandum and Articles of Association, as the same may be amended from time to time, the Rights shall expire and shall be worthless. 

4. Transfer and Exchange of Rights. 

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

4.2. Procedure for Surrender of Rights. Rights may be surrendered to the Rights Agent, together with a written request for exchange or
transfer, and thereupon the Rights Agent shall issue in exchange therefor one or more new Rights as requested by the registered holder of the Rights so surrendered, representing an equal aggregate number of Rights; provided, however, that in the
event that a Right surrendered for transfer bears a restrictive legend and the new Rights to be issued will not bear a restrictive legend, the Rights Agent shall not cancel such Right and issue new Rights in exchange therefor until the Rights Agent
has received an opinion of counsel for the Company stating that such transfer may be made and indicating no restrictive legend is required. 

4.3. Fractional Rights. The Rights Agent shall not be required to effect any registration of transfer or exchange which will result in
the issuance of a Right Certificate for a fraction of a Right. 
 4.4. Service Charges. No service charge shall be made for any
exchange or registration of transfer of Rights. 

  
 3 

 4.5. Right Execution and Countersignature. The Rights Agent is hereby authorized to
countersign and to deliver, in accordance with the terms of this Agreement, the Rights required to be issued pursuant to the provisions of this Section 4, and the Company, whenever required by the Rights Agent, will supply the Rights Agent with
Rights duly executed on behalf of the Company for such purpose. 
 5. Other Provisions Relating to Rights of Holders of Rights. 

5.1. No Rights as Shareholder. Until exchange of a Right for Ordinary Shares as provided for herein, a Right 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. 
 5.2. Lost,
Stolen, Mutilated, or Destroyed Rights. If any Right is lost, stolen, mutilated, or destroyed, the Company and the Rights 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 Right, include the surrender thereof), issue a new Right of like denomination, tenor, and date as the Right so lost, stolen, mutilated, or destroyed. Any such new Right shall constitute a substitute contractual obligation of the Company,
whether or not the allegedly lost, stolen, mutilated, or destroyed Right shall be at any time enforceable by anyone. 
 5.3. Reservation
of Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary Shares that will be sufficient to permit the exchange of all outstanding Rights issued pursuant to this Agreement.

 6. Concerning the Rights Agent and Other Matters. 

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

6.2. Resignation, Consolidation, or Merger of Rights Agent. 

6.2.1 Appointment of Successor Rights Agent. The Rights 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 Rights Agent becomes vacant by resignation or incapacity to act or otherwise, the Company
shall appoint in writing a successor Rights Agent in place of the Rights Agent. If the Company shall fail to make such appointment within a period of 30 days after it has been notified in writing of such resignation or incapacity by the Rights Agent
or by the holder of the Right (who shall, with such notice, submit his, her or its Right for inspection by the Company), then the holder of any Right may apply to the Supreme Court of the State of New York for the County of New York for the
appointment of a successor Rights Agent at the Company’s cost. Any successor Rights Agent, whether appointed by the Company or by such court, shall be a corporation organized and existing under the laws of the State of New York, in good
standing and having its principal office in the Borough of Manhattan, City and State of New York, 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 Rights Agent shall be vested with all the authority, powers, rights, immunities, duties, and obligations of its predecessor Rights Agent with like effect as if originally named as Rights Agent hereunder, without any
further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor Rights Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Rights Agent all the authority,
powers, and rights of such predecessor Rights Agent hereunder; and upon request of any successor Rights 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 Rights Agent all such authority, powers, rights, immunities, duties, and obligations. 

  
 4 

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

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

6.3. Fees and Expenses of Rights Agent. 

6.3.1 Remuneration. The Company agrees to pay the Rights Agent reasonable remuneration for its services as such Rights Agent hereunder
and will reimburse the Rights Agent upon demand for all expenditures that the Rights Agent may reasonably incur in the execution of its duties hereunder. 

6.3.2 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 Rights Agent for the carrying out or performing of the provisions of this Agreement. 

6.4. Liability of Rights Agent. 

6.4.1 Reliance on Company Statement. Whenever in the performance of its duties under this Agreement, the Rights Agent shall deem it
necessary or desirable that any fact or matter be proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed
to be conclusively proved and established by a statement signed by the Chief Executive Officer or Chief Financial Officer and delivered to the Rights Agent. The Rights Agent may rely upon such statement for any action taken or suffered in good faith
by it pursuant to the provisions of this Agreement. 
 6.4.2 Indemnity. The Rights Agent shall be liable hereunder only for its own
gross negligence, willful misconduct or bad faith. Subject to Section 6.6 below, the Company agrees to indemnify the Rights Agent and save it harmless against any and all liabilities, including judgments, costs and reasonable counsel fees, for
anything done or omitted by the Rights Agent in the execution of this Agreement except as a result of the Rights Agent’s gross negligence, willful misconduct, or bad faith. 

6.4.3 Exclusions. The Rights Agent shall have no responsibility with respect to the validity of this Agreement or with respect to the
validity or execution of any Right (except its countersignature thereof); nor shall it be responsible for any breach by the Company of any covenant or condition contained in this Agreement or in any Right; 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 Right or as to whether any Ordinary Shares will when issued be valid and fully paid and
nonassessable. 
 6.5. Acceptance of Agency. The Rights Agent hereby accepts the agency established by this Agreement and agrees to
perform the same upon the terms and conditions herein set forth. 
 6.6. Waiver. The Rights Agent hereby waives any 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 the Rights Agent 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.

 7.2. Notices. Any notice, statement or demand authorized by
this Agreement to be given or made by the Rights Agent or by the holder of any Right to or on the Company shall be sufficiently given when so delivered if by hand or overnight delivery or if sent by certified mail or private courier service within

 7.3. Applicable Law. The validity, interpretation, and performance of this Agreement
and of the Rights shall be governed in all respects by 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 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

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 Rights shall be deemed to have notice of and to
have consented to the forum provisions in this Section 7.3. If any action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within the State of New York or the
United States District Court for the Southern District of New York (a “foreign action”) in the name of any right holder, such right 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 right holder in any such enforcement action by service upon such right holder’s counsel in the foreign action as agent for such right holder. 

Any such process or summons to be served upon the Company may be served by transmitting a copy thereof by registered or certified mail, return
receipt requested, postage prepaid, addressed to it at the address set forth in Section 7.2 hereof. Such mailing shall be deemed personal service and shall be legal and binding upon the Company in any action, proceeding or claim. 

7.4. Persons Having Rights under this Agreement. Nothing in this Agreement expressed and nothing that may be implied from any of the
provisions hereof is intended, or shall be construed, to confer upon, or give to, any person or corporation other than the parties hereto and the registered holders of the Rights and, for the purposes of Sections 7.4 and 7.8 hereof, Maxim Group LLC,
any right, remedy, or claim under or by reason of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. Maxim Group LLC shall be deemed to be a third-party beneficiary of this Agreement with respect to Sections 7.4
and 7.8 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 Maxim Group LLC with respect to the Sections 7.4 and 7.8 hereof) and
their successors and assigns and of the registered holders of the Rights. The provisions of this Section 7.4 may not be modified, amended or deleted without the prior written consent of Maxim Group LLC. 

7.5. Examination of the Right Agreement. A copy of this Agreement shall be available at all reasonable times at the office of the
Rights Agent in the Borough of Manhattan, City and State of New York, for inspection by the registered holder of any Right. The Rights Agent may require any such holder to submit his, her or its Right for inspection by it. 

7.6. 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. 

7.7. 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. 
 7.8. Amendments. This Agreement may be amended by the parties hereto without the consent of any
registered holder for the purpose of curing any ambiguity, or of curing, correcting or supplementing any defective provision contained herein or adding or changing any other 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 interest of the registered holders. All other modifications or amendments shall require the written consent or vote of the registered
holders of a majority of the then outstanding Rights. The provisions of this Section 7.8 may not be modified, amended or deleted without the prior written consent of Maxim Group LLC. 

  
 7 

 7.9. 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.

February 7, 2022 
 Aurora Technology
Acquisition Corp. 
 4 Embarcadero Center 
 Suite 1449 

San Francisco, California 94105 
  

	 	Re:	 Initial Public Offering 

Ladies and Gentlemen: 
 This letter (this
“Letter Agreement”) is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and between Aurora Technology Acquisition Corp., a
Cayman Islands exempted company (the “Company”), and Maxim Group LLC (the “Representative”), as the representative of the several underwriters (the “Underwriters”), relating to
an underwritten initial public offering (the “Public Offering”) of up to 23,000,000 of the Company’s units (including up to 3,000,000 units that may be purchased to cover over-allotments, if any) (the
“Units”), each comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A ordinary shares”), and one right (the
“Right”). Each Right entitles the holder thereof to receive one-tenth (1/10) of one Class A ordinary share upon the consummation of the Company’s initial business combination,
subject to adjustment. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the
Securities and Exchange Commission (the “Commission”) and the Company shall apply to have the Units listed on the Nasdaq Global Market. Certain capitalized terms used herein are defined in paragraph 10 hereof. 

In order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for
other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, ATAC Sponsor LLC, a Delaware limited liability company (the “Sponsor”), and the other undersigned persons (each, an
“Insider” and collectively, the “Insiders”), hereby agrees with the Company as follows: 
 1. The Sponsor and
each Insider agrees that if the Company seeks shareholder approval of a proposed Business Combination (as defined below), then in connection with such proposed Business Combination, it, he or she shall (i) vote any Shares owned by it, him or
her in favor of any proposed Business Combination and (ii) not redeem any Shares owned by it, him or her in connection with such shareholder approval. 

2. (a) The Sponsor hereby agrees that in the event that the Company fails to consummate a Business Combination within 12 months, the time period by which the
Company must consummate a Business Combination may be extended by up to six months (or, if the Cayman Islands Registrar shall not be open for business (including filing of corporate documents) on such date the next date upon which the Cayman Islands
Registrar shall be open). If the Sponsor determines to seek such extension, the Sponsor will deposit into the Trust Account, for each additional three month period, $2,000,000, or up to $2,300,000 if the Underwriters’ over-allotment option is
exercised in full ($0.10 per share). Such extension payments would be made in the form of non-interest bearing loans to the Company (the “Extension Loans”), which are due and payable on the
consummation of a Business Combination out of the proceeds of the Trust Account released to the Company. Sponsor hereby waives its right to be repaid for any Extension Loans in the event that the Company does not consummate a Business Combination.

 (b) The Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 12
months from the closing of the Public Offering (or up to 18 months from the closing of the Public Offering if the Company extends the period of time to consummate a Business Combination, as described in more detail in the Prospectus), or such later
period approved by the Company’s shareholders in accordance with the Company’s amended and restated memorandum and articles of association, 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 ten (10) business days thereafter,
subject to lawfully available funds therefor, redeem 100% of the Class A ordinary shares sold as part of the Units in the Public Offering (the “Offering Shares”), at a per share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable and less up to $50,000 of interest to pay dissolution expenses), divided by the number of then outstanding Offering Shares, which
redemption will completely extinguish all Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible
following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to
provide for claims of creditors and other requirements of applicable law. The Sponsor and each Insider agrees to not propose any amendment to the Company’s amended and restated memorandum and articles of association (a) that would affect
the ability of Public Shareholders to exercise redemption rights with respect to the Offering Shares or modify the substance or timing of the Company’s obligation to redeem 100% of the Offering Shares if the Company does not complete a Business
Combination within 12 months (or up to 18 months) from the closing of the Public Offering, or (b) with respect to any other provision relating to shareholders’ rights or pre-initial Business
Combination activity, unless the Company provides its Public Shareholders with the opportunity to redeem their Offering 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 (which interest shall be net of taxes payable), divided by the number of then outstanding Offering Shares. 

The Sponsor and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or to any monies held in
the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares (as defined below) held by it. The Sponsor and each Insider hereby further waives, with respect to any Shares held
by it, him or her, if any, any redemption rights it, he or she 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 in the context of a tender offer made by the Company to purchase Class A ordinary shares (although the Sponsor and the Insiders shall be entitled to redemption and liquidation rights with respect to any Offering Shares
it or they hold if the Company fails to consummate a Business Combination within 12 months (or up to 18 months) from the closing of the Public Offering, or such later period approved by the Company’s shareholders in accordance with the
Company’s amended and restated memorandum and articles of association). 
 3. In the event of the liquidation of the Trust Account, the Sponsor (which
for purposes of clarification shall not extend to any other equity holders, members or managers of the Sponsor) 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, or any claim whatsoever) to which the Company may become subject as a result
of any claim by (i) any third party (other than the Company’s independent public accountants) for services rendered or products sold to the Company or (ii) a 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 Sponsor shall apply only to the extent necessary to ensure that such claims by a third party for
services rendered (other than the Company’s independent public accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.00 per share of the Offering Shares or
(ii) such lesser amount per share of the Offering Shares held in the Trust Account due to reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount of interest earned on
the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under
the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended. In the event that any such executed waiver is deemed to be unenforceable against such third party, the
Sponsor shall not be responsible to the extent of any liability for such third party claims. The Sponsor 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 Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

 4. To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an
additional 3,000,000 Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees that it shall forfeit, at no cost, a number of Founder Shares in the aggregate equal to 750,000 multiplied by
a fraction, (i) the numerator of which is 3,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which is 3,000,000. 

All references in this Letter Agreement to Founder Shares of the Company being forfeited shall take effect as surrenders for no consideration
of such Founder Shares as a matter of Cayman Islands law. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters so that the Founder Shares will represent 20.0% of the Company’s
issued and outstanding Shares after the Public Offering (assuming the Initial Shareholders do not purchase any units in the Public Offering and excluding the Representative Shares and Private Shares). The Initial Shareholders further agree that to
the extent that the size of the Public Offering is increased or decreased, the Company will effect a capitalization or share repurchase or redemption or other appropriate mechanism, as applicable, immediately prior to the consummation of the Public
Offering in such amount as to maintain the ownership of the Initial Shareholders prior to the Public Offering at 20.0% of the Company’s issued and outstanding Shares upon the consummation of the Public Offering (assuming the Initial
Shareholders do not purchase any units in the Public Offering and excluding the Representative Shares and Private Shares). In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 3,000,000 in
the numerator and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of Class A ordinary shares included in the Units issued in the Public Offering and (B) the
reference to 750,000 in the formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Founder Shares would represent an aggregate of 20.0% of the Company’s issued and outstanding Shares
after the Public Offering (assuming the Initial Shareholders do not purchase any units in the Public Offering and excluding the Representative Shares). 
 5.
The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured in the event of a breach by such Sponsor or Insider of its, his or her obligations under paragraphs 1, 2, 3, 4,
6(a), 6(b) and 8 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party shall be entitled to seek injunctive relief, in
addition to any other remedy that such party may have in law or in equity, in the event of such breach. 
 6. (a) The Sponsor and each Insider agrees that
it, he or she shall not Transfer (as defined below) any Founder Shares (or Class A ordinary shares issuable upon conversion thereof) until the earlier of (A) six months after the date of the completion of the Company’s initial
Business Combination, (B) the date on which the closing price of the Company’s Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like)
for any 20 trading days within any 30-trading day period commencing after the Company’s initial Business Combination, or (C) the date on which the Company completes a liquidation, merger, share
exchange or other similar transaction which results in all of the Company’s shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property (the “Founder Shares Lock-up Period”). 
 (b) The Sponsor and each Insider agrees that it, he or she shall not
Transfer any Private Warrants until 30 days after the completion of a Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”). 

  
 3 

 (c) Notwithstanding the provisions set forth in paragraphs 6(a) and 6(b), Transfers of the
Founder Shares and Private 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 members of the Sponsor or any affiliates of the
Sponsor; (b) in the case of an individual, by gift to a member of the individual’s immediate family, or to a trust, the beneficiary of which is a member of the individual’s immediate family or 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 securities were originally purchased; (f) in the event of the Company’s liquidation
prior to the Company’s completion of an initial Business Combination; (g) by virtue of the laws of the Cayman Islands or the Sponsor’s limited liability company agreement, as amended from time to time, upon termination or dissolution
of the Sponsor; or (h) in the event of the Company’s completion of a liquidation, merger, amalgamation, share exchange, reorganization or other similar transaction which results in all of the Company’s shareholders having the right to
exchange their Class A ordinary shares for cash, securities or other property subsequent to the completion of the Company’s initial Business Combination; provided, however, that, except in the case of clause (f) or with the
Company’s prior consent, 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. 

7. The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership in any securities or
commodities exchange or association or had a securities or commodities license or registration denied, suspended or revoked. Each Insider’s biographical information furnished to the Company, if any (including any such information included in
the Prospectus), is true and accurate in all respects and does not omit any material information with respect to such Insider’s background. The Sponsor and each Insider’s questionnaire furnished to the Company, if any, is true and accurate
in all respects. The Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for, any injunction,

has never been convicted of, or pleaded guilty to, any crime (i) involving fraud, (ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities and it, he or
she is not currently a defendant in any such criminal proceeding. 
 8. Except as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any
affiliate of the Sponsor or any Insider, nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment 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). 

9. The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including, without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this Letter Agreement and, as applicable, to serve as an officer and/or
director on the board of directors of the Company and hereby consents to being named in the Prospectus as an officer/and or director of the Company.

assignment of, offer to sell, contract or agreement to sell, hypothecate, pledge, grant of any option to purchase or otherwise dispose of or agreement to dispose of, directly or indirectly, or establishment or increase of a put equivalent position

11. This Letter Agreement constitutes the entire agreement and understanding of the parties hereto in respect of the subject matter hereof and supersedes all

or waiver. 
 12. 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 and each Insider and their respective successors, heirs and assigns and Permitted Transferees. 
 13. 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. 

14. This Letter Agreement shall be deemed severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or

 17. Each party hereto shall not be liable for any breaches or misrepresentations contained in this Letter
Agreement by any other party to this Letter Agreement (including, for the avoidance of doubt, any Insider with respect to any other Insider), and no party shall be liable or responsible for the obligations of another party, including, without
limitation, indemnification obligations and notice obligations.
