 Recitals 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization
or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the Company has
confidentially submitted to the U.S. Securities and Exchange Commission (the “SEC”) a draft registration statement on Form S-1 (the “Registration Statement”) for its initial
public offering (“IPO”) of 20,000,000 units (or 23,000,000 units in the aggregate if the underwriter’s over-allotment is exercised in full) (the “Public Units”) at a price of $10.00 per Public Unit, each
comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Share(s)”), and one-half of one redeemable warrant, where each whole

WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to identify and consummate a Business
Combination; 
 WHEREAS, the parties wish to enter into this Agreement, pursuant to which (i) immediately prior to the closing of the
Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Purchaser shall purchase, on a private placement basis, the number of Class A Shares determined
pursuant to Section 1(a)(i) hereof (the “Forward Purchase Shares”) and the applicable number of Warrants determined pursuant to Section 1(a)(i) hereof, with one Warrant being issuable to the Purchaser per each increment of
four (4) Forward Purchase Shares actually issued and sold to the Purchaser hereunder (the “Forward Purchase Warrant(s)” and together with the Forward Purchase Shares, the “Forward Purchase Units”) and
(ii) concurrently herewith, the Sponsor will transfer to the Purchaser, on a private placement basis, Class B ordinary shares of the Company, par value $0.0001 per share (the “Class B Share(s)”), in an
amount equal to the Class B Shares Transfer Amount determined pursuant to Section 1(b) hereof, in each case on the terms and conditions set forth herein; 

WHEREAS, the Class B Shares are automatically convertible into Class A Shares following the Business Combination Closing on the
terms and conditions set forth in the Company’s memorandum and articles of association, as it may be amended from time to time (the “Charter”); and 

 WHEREAS, the Company has entered, or intends concurrently with this entry into this
Agreement to enter, into one or more agreements (collectively, the “Forward Contracts”) substantially in the form of this Agreement with other third parties (together with the Purchaser, the “Forward Contract
Parties” and each, a “Forward Contract Party”) for the purchase of Class A Shares and Warrants upon the Business Combination Closing (all Class A Shares to be purchased pursuant to such Forward Contracts, together
with the Forward Purchase Shares, collectively, the “Total Forward Purchase Shares”), and for the transfer by the Sponsor to such third parties of Class B Shares upon execution of such Forward Contracts. 

NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for
other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

Agreement 
 1. Sale and
Purchase. 
 (a) Forward Purchase Units. 

(i) The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the number of Forward Purchase
Shares set forth on the signature page to this Agreement next to the line item “Number of Forward Purchase Shares,” plus the number of Forward Purchase Warrants set forth on the signature page to this Agreement next to the line item
“Number of Forward Purchase Warrants,” for an aggregate purchase price of $10.00 multiplied by the number of Forward Purchase Units issued and sold hereunder (the “FPU Purchase Price”). No fractional Forward Purchase
Warrants will be issued. 
 (ii) Each Forward Purchase Warrant will have the same terms as each Warrant sold as part of the Public Units in
the IPO (“Public Warrants”) and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection
with the IPO (the “Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement,
and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable on the later of thirty (30) days after the Business Combination Closing and twelve (12) months from the IPO Closing, and
will expire at 5:00 p.m., New York City time, five (5) years after the Business Combination Closing or earlier upon redemption or the liquidation of the Company, as described in the Warrant Agreement. 

(iii) The Company shall require the Purchaser to purchase the Forward Purchase Shares and the Forward Purchase Warrants pursuant to
Section 1(a)(i) hereof by delivering notice to the Purchaser, at least ten (10) Business Days before the funding of the FPU Purchase Price to the Escrow Account (as defined below), specifying the number of Forward Purchase Shares and
Forward Purchase Warrants the Purchaser is required to purchase, the anticipated date of the Business Combination Closing, the aggregate FPU Purchase Price and instructions for wiring the FPU Purchase Price to an account of a third-party escrow
agent (the “Escrow Account”), which shall be the Company’s transfer agent (the “Escrow Agent”), pursuant to an escrow agreement between the Company and the Escrow Agent (the “Escrow 

  
 2 

 Agreement”). At least two (2) Business Days before the anticipated date of the Business
Combination Closing specified in such notice, the Purchaser shall deliver the FPU Purchase Price in cash via wire transfer to the account specified in such notice, to be held in escrow pending the Business Combination Closing. If the Business
Combination Closing does not occur within thirty (30) days after the Purchaser delivers the FPU Purchase Price to the Escrow Agent, the Escrow Agreement will provide that the Escrow Agent shall automatically return to the Purchaser the FPU
Purchase Price, provided that the return of the FPU Purchase Price placed in escrow shall not terminate the Agreement or otherwise relieve either party of any of its obligations hereunder. For the purposes of this Agreement, “Business Day”
means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation to close in the City of New York, New York, or Hong Kong. 

(iv) The closing of the sale of the Forward Purchase Units (the “FPU Closing”) shall be held on the same date and immediately
prior to the Business Combination Closing (such date being referred to as the “Closing Date”). At the FPU Closing, the Company will issue to the Purchaser the Forward Purchase Units, each registered in the name of the Purchaser,
against (and concurrently with) release of the FPU Purchase Price by the Escrow Agent to the Company. 
 (b) Class B Shares. In
consideration of the Purchaser’s agreement to purchase Forward Purchase Units, the Sponsor shall transfer to the Purchaser the number of Class B Shares set forth in Schedule A to this Agreement next to the line item “Class B
Shares Transfer Amount,” which shall be calculated in accordance with the definition of Class B Shares Transfer Amount set forth in Schedule A to this Agreement. The Class B Shares received by the Purchaser hereunder are subject to
forfeiture in accordance with Section 5(b) hereof. The transfer of the Class B Shares (the “Class B Share Transfer”) to the Purchaser shall take place concurrently with the execution of this Agreement.

 (c) Delivery of Securities. 

(i) The Company shall register the Purchaser as the owner of the Forward Purchase Units purchased, and the Class B Shares received, by
the Purchaser hereunder (individually or collectively, the “Securities”) in the register of members of the Company and with the Company’s transfer agent by book entry on or promptly after (but in no event more than two
(2) Business Days after) the date of the FPU Closing and the Class B Share Transfer, respectively. 
 (ii) Each register and book
entry for the Securities shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE
SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.” 

  
 3 

 (iii) Each register and book entry for the Class B Shares transferred to the Purchaser
shall contain a notation, and each certificate (if any) evidencing such Class B Shares shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SALE, PLEDGE, HYPOTHECATION, OR TRANSFER OF THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN
FORWARD PURCHASE AGREEMENT BY AND AMONG THE HOLDER AND THE OTHER PARTIES THERETO. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.” 

(d) Legend Removal. Following the expiration of the transfer restrictions set forth in Section 5(a), if the Securities are eligible
to be sold without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), or there is an
effective registration statement covering the resale of the Securities (and the Purchaser provides the Company with a written undertaking to sell its Securities only in accordance with the plan of distribution contained in such registration
statement and only if such Purchaser has not been informed that the prospectus in such registration statement is not current or the registration statement is no longer effective), then at the Purchaser’s request, the Company will cause the
Company’s transfer agent to remove the legend set forth in Section 1(c)(ii) and Section 1(c)(iii). In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be
delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to transfer such Securities without any such legend;
provided, that, notwithstanding the foregoing, the Company will not be required to deliver any such opinion, authorization, certificate or direction if it reasonably believes that removal of the legend could result in or facilitate transfers of
Securities in violation of applicable law. 
 (e) Registration Rights. The Purchaser shall have registration rights as set forth on
Exhibit A (the “Registration Rights”). 
 2. Representations and Warranties of the Purchaser. The
Purchaser represents and warrants to the Company as follows, as of the date hereof: 
 (a) Organization and Power. If an entity, the
Purchaser is duly organized, validly existing, and in good standing under the laws of the jurisdiction of its formation (if the concept of “good standing” is a recognized concept in such jurisdiction) and has all requisite power and
authority to carry on its business as presently conducted and as proposed to be conducted. 
 (b) Authorization. The Purchaser has
full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except
(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable remedies, or (iii) to the extent the indemnification provisions contained in the Registration Rights may be limited by applicable federal or state securities laws.

  
 4 

 (c) Governmental Consents and Filings. No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated by this
Agreement. 
 (d) Compliance with Other Instruments. The execution, delivery and performance by the Purchaser of this Agreement and
the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, if applicable, (ii) of any instrument, judgment, order,
writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to which it is a party
or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would have a material adverse effect on the Purchaser or its ability to
consummate the transactions contemplated by this Agreement. 
 (e) Purchase Entirely for Own Account. This Agreement is made with the
Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Securities to be acquired by the Purchaser will be acquired for
investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or
otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or
grant participations to such Person or to any third Person, with respect to any of the Securities. If the Purchaser was formed for the specific purpose of acquiring the Securities, each of its equity owners is an accredited investor as defined in
Rule 501(a) of Regulation D promulgated under the Securities Act. For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated
organization, any other entity or any government or any department or agency thereof. 
 (f) Disclosure of Information. The Purchaser
has had an opportunity to discuss the Company’s business, management, financial affairs and the terms and conditions of the offering of the Securities, as well as the terms of the Company’s proposed IPO, with the Company’s management.

 (g) Restricted Securities. The Purchaser understands that the Securities have not been registered under the Securities Act, by
reason of a specific exemption from the registration provisions of the Securities Act which depends upon, among other things, the bona fide nature of the investment intent and the accuracy of the Purchaser’s representations as expressed herein.
The Purchaser understands that the Securities are “restricted securities” under 

  
 5 

 
applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the Securities indefinitely unless they are registered with the SEC and qualified by
state authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the Company has no obligation to register or qualify the Securities, or any Class A Shares into which they
may be converted into or exercised for, for resale, except pursuant to the Registration Rights. The Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on various requirements
including, but not limited to, the time and manner of sale, the holding period for the Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is under no obligation and may
not be able to satisfy. The Purchaser acknowledges that the Company confidentially submitted the Registration Statement for its proposed IPO to the SEC for review. The Purchaser understands that the offering to the Purchaser of the Securities is
not, and is not intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11 of the Securities Act with respect to such Securities. 

(h) No Public Market. The Purchaser understands that no public market now exists for the Securities, and that the Company has made no
assurances that a public market will ever exist for the Securities. 
 (i) High Degree of Risk. The Purchaser understands that its
agreement to purchase the Securities involves a high degree of risk which could cause the Purchaser to lose all or part of its investment, and that it will be contractually obligated to vote its Class B Shares in favor of the Company’s
initial Business Combination. 
 (j) Accredited Investor. The Purchaser is an “accredited investor” as defined in Rule
501(a) of Regulation D promulgated under the Securities Act. 
 (k) Foreign Investors. If the Purchaser is not a United States person
(as defined by Section 7701(a)(30) of the U.S. Internal Revenue Code of 1986, as amended, and the regulations promulgated thereunder (collectively, the “Code”)), the Purchaser hereby represents that it has satisfied itself as
to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Securities or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the
Securities, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to
the purchase, holding, redemption, sale, or transfer of the Securities. The Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the
Purchaser’s jurisdiction. 
 (l) No General Solicitation. Neither the Purchaser, nor any of its officers, directors, employees,
agents, stockholders or partners has either directly or indirectly, including, through a broker or finder (i) to its knowledge, engaged in any general solicitation, or (ii) published any advertisement in connection with the offer and sale

(q) No Other Representations and Warranties; Non-Reliance. Except for the specific
representations and warranties contained in this Section 2 and in any certificate or agreement delivered pursuant hereto, none of the Purchaser nor any person acting on behalf of the Purchaser nor any of the Purchaser’s affiliates (the

or exercisable for equity securities, other than the Public Units (and their component Class A Shares, Public Warrants and the Class A Shares underlying the Public Warrants) and Excluded Securities (as defined below) (“New Equity
Securities”), the Company shall first make an offer of the applicable pro rata portion of New Equity Securities to the Purchaser, which portion will be determined by dividing (a) the FPU Purchase Price to be paid by

(a) Offer Notice. 

(i) The Company shall give written notice (the “Offering Notice”) to the Purchaser and the other Forward Contract

Period, the Purchaser shall be deemed to have waived all of the Purchaser’s rights to purchase the New Equity Securities offered pursuant to the Offering Notice under this Section, and the Company shall thereafter be free to sell or enter into
an agreement to sell the Purchaser’s pro rata portion of such New Equity Securities to any third party (including any Forward Contract Parties) without any further obligation to the Purchaser pursuant to this Section within the
ninety (90) day period thereafter (and with respect to an agreement to sell, consummate such sale at any time thereafter) on terms and conditions not more favorable to the third party than those set forth in the Offering Notice. If the Company
does not sell or enter into an agreement to sell the Purchaser’s pro rata portion of the New Equity Securities within such period, the rights provided hereunder shall be deemed to be revived and the New Equity Securities shall
not be offered to any third party unless first re-offered to the Purchaser in accordance with this Section. 

(c) Excluded Securities. For purposes hereof, the term “Excluded Securities” means Class B Shares (and
Class A Shares into which such Class B Shares are convertible) issued to the Sponsor prior to the IPO, the private placement warrants sold to the Sponsor or its affiliates in connection with the IPO (the “Private Placement
Warrants”), warrants issued upon the conversion of working capital loans to the Company to be made by the Sponsor or an affiliate thereof to finance transaction costs in connection with an intended initial Business Combination (up to
$1,500,000 of which may be convertible at the option of the lender into warrants of the post-Business Combination entity having the same terms as the Private Placement Warrants at a price of $1.00 per warrant), any securities issued by the Company
as consideration to any seller in the Business Combination, and any Class A Shares, Class B Shares (and Class A Shares into which such Class B Shares are convertible) and Forward Purchase Warrants issued pursuant to forward
purchase contracts entered into prior to the IPO Closing with Forward Contract Parties. 
 5. Additional Agreements and Acknowledgements
and Waivers of the Purchaser. 
 (a) Lock-up; Transfer Restrictions. The Purchaser agrees
that it shall not Transfer (as defined below) any Class B Shares owned by it and the Class A Shares into which such Class B Shares are convertible, until the earlier of (A) one year after the Business Combination Closing and
(B) the date following the Business Combination Closing on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s ordinary shareholders having the right to
exchange their ordinary shares of the Company for cash, securities or other property. Notwithstanding the foregoing, if, subsequent to a Business Combination, the closing price of the Class A Shares equals or exceeds $12.00 per share (as
adjusted for share sub-divisions, share capitalization, 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 Business Combination Closing, the Class B Shares (and the Class A Shares into which the Class B Shares are convertible) shall be released from the lockup referred to in this
Section 5(a). Notwithstanding the first sentence hereinabove, Transfers of the Class B Shares (and the Class A Shares into which the Class B Shares are convertible) are permitted (i) to the Company’s officers or
directors, any affiliates or family members of any of the Company’s officers or directors, any 

  
 12 

 
members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (ii) 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, an affiliate of such person or to a charitable organization; (iii) in the case of an individual, by virtue of laws
of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers made in connection with the consummation of a Business
Combination at prices no greater than the price at which the Class B Shares were originally purchased; (vi) by virtue of the Purchaser’s organizational documents upon liquidation or dissolution of the Purchaser; (vii) in the
event of the Company’s liquidation prior to the completion of a Business Combination; or (viii) in the event of the Company’s completion of 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 Shares for cash, securities or other property subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (i) through (vi)
these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions. As used in this Agreement, “Transfer” shall mean the (x) sale of, offer to sell, contract or agreement to
sell, hypothecation, 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 or liquidation with respect to or decrease of a call
equivalent position (within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”, and the rules and regulations of the SEC promulgated thereunder) with respect to, any of the
Securities (excluding any pledges in the ordinary course of business for bona fide financing purposes or as part of prime brokerage arrangements), (y) entry into any swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of any of the Securities, whether any such transaction is to be settled by delivery of such Securities, in cash or otherwise, or (z) public announcement of any intention to effect any transaction specified
in clause (x) or (y). For the avoidance of doubt, this Section 5(a) shall not restrict the ability to exercise any Forward Purchase Warrants in accordance with their terms. For the further avoidance of doubt, “Transfer” does not
include any transfer of such Class B Shares (and the Class A Shares into which the Class B Shares are convertible) among any of the investment funds or managed accounts managed by the Purchaser. 

(b) Potential Forfeiture. The Purchaser agrees that, to the extent that it fails to pay the FPU Purchase Price when required in
accordance with Section 1 hereof and such failure to pay remains uncured after five (5) Business Days’ notice from the Company, the Purchaser shall forfeit to the Company all of its Class B Shares. If the Purchaser fails to
forfeit any Class B Shares it is required to forfeit hereunder, the Purchaser hereby grants hereunder to the Company and any representative designated by the Company without further action by the Purchaser a limited irrevocable power of
attorney to effect such forfeiture on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest. Any forfeiture under this Agreement shall take effect as a surrender for no consideration as a matter of Cayman
Islands law. 

  
 13 

 (c) Waiver of Adjustment to Conversion Price and Recapitalization Shares. In the
event that the Company issues equity or equity-linked securities in addition to the Forward Purchase Units in connection with the Business Combination Closing and the Sponsor waives, in whole or in part, its right to have its Class B Shares
converted into a greater number of Class A Shares in respect of such issuance pursuant to the Charter, such waiver shall also automatically waive such right on behalf of the Purchaser in respect of the Purchaser’s Class B Shares on a
pro rata basis. In addition, the Purchaser: (i) agrees that it waives its right to receive any additional Class B Shares in the event of any share split, share capitalization, reorganization or recapitalization of or in respect of the
Class B Shares prior to the IPO Closing that is effected in order to increase the number of issued and outstanding Class B Shares due to an increase in the number of Class A Shares being sold in the IPO (“Share
Capitalization”); (ii) directs the Company to issue its portion of a Share Capitalization to the Sponsor; and (iii) confirms that it has no claims against the Company, or its directors, officers, employees or other shareholders in respect
of a Share Capitalization. 
 (d) Trust Account. 

(i) The Purchaser hereby acknowledges that it is aware that the Company will establish a trust account (the “Trust Account”)
for the benefit of its public shareholders upon the IPO Closing. The Purchaser, for itself and its affiliates, hereby agrees that it 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, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Class A Shares issued in the IPO (the “Public Shares”) held by it.

 (ii) The Purchaser hereby agrees that it shall have no right of set-off or any right, title,
interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future, except for redemption and
liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser shall pursue such Claim solely against the Company and
its assets outside the Trust Account and not against the property or any monies in the Trust Account, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. 

(e) Redemption and Liquidation. The Purchaser hereby waives, with respect to any Class B Shares (including the Class A Shares
into which such Class B Shares are convertible) held by it, any redemption rights it may have in connection with (i) the consummation of a Business Combination, including any such rights available in the context of a shareholder vote to
approve such Business Combination and (ii) any shareholder vote to approve an amendment to the Charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Class A Shares sold in the IPO if the
Company has not consummated an initial Business Combination within the time period set forth in the Charter or in the context of a tender offer made by the Company to purchase Class A Shares, it being understood that the Purchaser shall be
entitled to redemption and liquidation rights with respect to any Public Shares beneficially owned by it. 

  
 14 

 (f) Voting. The Purchaser hereby agrees that if the Company seeks shareholder
approval of a proposed Business Combination, then in connection with such proposed Business Combination, the Purchaser shall vote any Class B Shares and Class A Shares owned by it in favor of any proposed Business Combination. If the
Purchaser fails to vote any Class B Shares or Class A Shares it is required to vote hereunder in favor of a Proposed Business Combination, the Purchaser hereby grants to the Company and any representative designated by the Company without
further action by the Purchaser a limited irrevocable power of attorney to effect such vote on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest. 

(g) No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any
understanding with it, will engage in any Short Sales with respect to securities of the Company prior to the Business Combination Closing. For purposes of this Section, “Short Sales” shall include, without limitation, all
“short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage
arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign
regulated brokers. 
 6. Additional Agreements of the Sponsor and the Company. 

(a) Sponsor Class B Share Lock-up. The Sponsor agrees that it shall not, and
shall cause its affiliates and permitted transferees not to, Transfer any Class B Shares or Class A Shares into which such Class B Shares are convertible (the “Sponsor Shares”) until the earliest of (1) one year
after the Business Combination Closing and (2) subsequent to a Business Combination, (x) the closing price of the Class A Shares equals or exceeds $12.00 per share (as adjusted for share
sub-divisions, share capitalization, 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 Business Combination Closing or (y) the date following the Business Combination Closing on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the
Company’s ordinary shareholders having the right to exchange their ordinary shares of the Company for cash, securities or other property. Notwithstanding the foregoing, the Sponsor, its affiliates and its and their permitted transferees will be
permitted to Transfer the Sponsor Shares in accordance with clauses (i) through (viii) of Section 5(a) of this Agreement (applied mutatis mutandis), subject to the requirement that these permitted transferees must enter into a
written agreement agreeing to be bound by the transfer restrictions set forth in Section 6(a) of this Agreement. 
 (b) QEF Election;
Tax Information. The Company shall use commercially reasonable efforts to determine whether, in any year, the Company (or any subsidiary of the Company) is deemed to be a “passive foreign investment company” (a “PFIC”)
or a “controlled foreign corporation” (a “CFC”) within the meaning of the Code, and shall notify the Purchaser if the Company (or any subsidiary of the Company) is deemed to be a PFIC or CFC. If the Company determines that
the Company (or any subsidiary of the Company) is a PFIC in any year, for the year of determination and for each year thereafter during which the Purchaser holds an equity interest in the Company, including Warrants, and the Purchaser is subject to
income tax in the United States, the Company shall use commercially reasonable efforts to (i) make available to the Purchaser the information that may be required to make or maintain a “qualified electing fund” election under the Code
with respect to the Company (or any subsidiary of the Company, as applicable) and (ii) furnish the information required to be reported under Section 1298(f) of the Code or under any other applicable tax law. 

  
 15 

 (c) Minimum IPO Size. The Company will offer at least 15,000,000 Public Units in the
IPO. Each Public Unit will be comprised of one Class A Share and no more than one-half of one Warrant. Each whole Warrant will have an exercise price of not less than $11.50 per share. 

(d) No Material Non-Public Information. The Company and the Sponsor agree that no
information provided to the Purchaser in connection with this Agreement will, upon the IPO Closing, constitute material non-public information of the Company, and following the IPO Closing, neither the Company
nor the Sponsor will provide the Purchaser with any material non-public information of the Company (including any material non-public information with respect to any
other Person in connection with any proposed Business Combination) without the prior written consent of the Purchaser. 
 (e) Nasdaq
Listing. The Company will use commercially reasonable efforts to effect the listing of the Class A Shares and Warrants on Nasdaq (or another national securities exchange). 

(f) No Amendments to Charter. The Charter of the Company will be in substantially the same form of Exhibit B hereto and will not
be materially amended prior to the IPO Closing without the Purchaser’s prior written consent. 
 6A. Transfer. This
Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation to purchase the Forward Purchase Units) may be transferred or assigned, at any time and from time to time, in whole or in part, to
one or more third parties (each such transferee, a “Transferee”), subject to the prior written consent of the Company (not to be unreasonably denied, withheld or delayed). Upon any such assignment: 

(a) the applicable Transferee shall execute a signature page to this Agreement, substantially in the form of the Purchaser’s signature
page hereto (the “Joinder Agreement”), which shall reflect the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by such Transferee (the “Transferee Securities”), and, upon such
execution, such Transferee shall have all the same rights and obligations of the Purchaser hereunder with respect to the Transferee Securities, and references herein to the “Purchaser” shall be deemed to refer to and include any such
Transferee with respect to such Transferee and to its Transferee Securities; provided, that any representations, warranties, covenants and agreements of the Purchaser and any such Transferee shall be several and not joint and shall be made as to the
Purchaser or any such Transferee, as applicable, as to itself only; and 
 (b) upon a Transferee’s execution and delivery of a Joinder
Agreement, the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the Purchaser hereunder shall be reduced by the total number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the applicable
Transferee pursuant to the applicable Joinder Agreement, which reduction shall be evidenced by the Purchaser and the Company amending the “Number of Forward Purchase Shares”, “Number of Forward Purchase

  
 16 

 
Warrants”, and “Aggregate Purchase Price for Forward Purchase Units” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Units, and the
Purchaser shall be fully and unconditionally released from its obligation to purchase such Transferee Securities hereunder. For the avoidance of doubt, this Agreement need not be amended and restated in its entirety, but only the Purchaser’s
signature page hereto need be so amended and updated and executed by each of the Purchaser and the Company upon the occurrence of any such transfer of Transferee Securities.

 In the event of any termination of this Agreement pursuant to this Section 8, the FPU
Purchase Price (and interest thereon, if any), if previously paid, and all Purchaser’s funds paid in connection herewith shall be promptly returned to the Purchaser, and thereafter this Agreement shall forthwith become null and void and have no
effect, without any liability on the part of the Purchaser or the Company and their respective directors, officers, employees, partners, managers, members, or shareholders and all rights and obligations of each party shall cease; provided,
however, that nothing contained in this Section 8 shall relieve either party from liabilities or damages arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants or agreements
contained in this Agreement.

 19 

 (e) Successors. All of the terms, agreements, covenants, representations, warranties,
and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties hereto and their respective successors. Nothing in this Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

(f) Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval of the other parties. 
 (g) Counterparts. This
Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. 

(h) Headings. The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the
meaning or interpretation of this Agreement. 
 (i) Governing Law. This Agreement, the entire relationship of the parties hereto, and
any dispute between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of Hong Kong. 

(j) Jurisdiction/Arbitration. The Parties agree that all disputes arising under, or relating to, this Agreement shall be resolved in

The language of the proceedings shall be English. 
 (k) Waiver of Jury Trial. The parties hereto hereby waive any right to a jury
trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby. 
 (l) Amendments. This
Agreement may not be amended, modified or waived as to any particular provision, except with the prior written consent of the Company, the Sponsor and the Purchaser. 

(m) Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will
not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not
to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such
that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced. 

  
 20 

 (n) Expenses. Each of the Company and the Purchaser will bear its own costs and
expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors, legal
counsel and accountants. The Company shall be responsible for the fees of its transfer agent, stamp taxes and all of The Depository Trust Company’s fees associated with the issuance of the Securities and the securities issuable upon conversion
or exercise of the Securities. 
 (o) 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. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires
otherwise. 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 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. 
 (p) Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence. 

(q) Confidentiality. Except as may be required by law, regulation or applicable stock exchange listing requirements, unless and until
the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall not publicly disclose the existence or terms of this Agreement.

 (r) Specific Performance. The Purchaser agrees that irreparable damage would occur in the event that any provision of this
Agreement was not performed by the Purchaser in accordance with the specific terms hereof or was otherwise breached, and that money damages or legal remedies would not be an adequate remedy for any such damages. Therefore, it is accordingly agreed
that the Company shall be entitled to enforce specifically the 

  
 21 

 
terms and provisions of this Agreement, or to enforce compliance with, the covenants and obligations of the Purchaser, in any arbitration proceeding, and may also seek preliminary injunctive
relief in aid of arbitration in any court of competent jurisdiction in addition to any other remedy to which the Company is entitled at law or in equity. 

(s) Most Favored Nations. The Company hereby represents and warrants that as of the date hereof, and covenants and agrees that
after the date hereof, none of the agreements with other Forward Contract Parties or any other person for the purchase of Forward Purchase Units, includes or will include terms, rights or other benefits that are more favorable, in any material
respect, to such other Person than the terms, rights and benefits in favor of the Purchaser under this Agreement, and the Company will not amend any of the material terms, rights or benefits in, or waive any material obligation under, any of the
agreements with such other Person unless, in any such case, the Purchaser has been offered in writing the opportunity to concurrently receive the benefits of all such terms, rights and benefits or waiver. The Purchaser shall notify the Company in
writing, within ten (10) days after the date it has been offered the opportunity to receive the benefit of such terms, rights, benefits or waiver, of its election to receive any such term, right, benefit or waiver so offered.

 Purchaser ’s Forward Purchase Percentage = Quotient of (A) Number of Forward Purchase Shares divided by
(B) Total Forward Purchase Shares. 
 Total Forward Purchase Shares = 3,000,000 

Total Class B Shares Transfer Amount = 375,001 

 

	1 	 The Total Class B Shares Transfer Amount is subject to the final number of Total Forward Purchase Shares.

	*	 The percentage break-downs set out herein regarding the amounts of Forward Purchase Shares, Forward Purchase
Warrants and Aggregate Purchase Price for Forward Purchase Units to be respectively purchased and paid by such funds managed by the Purchaser may be subject to subsequent adjustments as advised by the Purchaser any time not later than five
(5) Business Days before the anticipated date of the Business Combination Closing as contemplated under clause 1 (a)(iii), provided that the aggregate numbers of Forward Purchase Shares, Forward Purchase Warrants and Aggregate Purchase Price
for Forward Purchase Units stated herein will not be adjusted. 

 Exhibit A 

Registration Rights 
 1.
Within thirty (30) days after the Business Combination Closing, the Company shall use reasonable best efforts (i) to file a registration statement on Form S-3 for a secondary offering (including any
successor registration statement covering the resale of the Registrable Securities a “Resale Shelf”) of (x) the Class A Shares and Warrants (and underlying Class A Shares) comprising the Forward Purchase Units and the
Class A Shares into which the Class B Shares are convertible, (y) any other Class A Shares and Warrants that may be acquired by the Purchaser after the date of this Agreement, including any time after the Business Combination
Closing and (z) any other equity security of the Company issued or issuable with respect to the securities referred to in clauses (x) and (y) by way of a share capitalization or share sub-division or
in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (collectively, the “Registrable Securities”) pursuant to Rule 415 under the Securities Act; provided, that if Form S-3 is unavailable for such a registration, the Company shall register the resale of the Registrable Securities on another appropriate form and undertake to register the Registrable Securities on Form S-3 as soon as such form is available, (ii) to cause the Resale Shelf to be declared effective under the Securities Act promptly thereafter, but in no event later than sixty (60) days thereafter, and
(iii) to maintain the effectiveness of such Resale Shelf with respect to the Purchaser’s Registrable Securities until the earliest of (A) the date on which the Purchaser ceases to hold Registrable Securities covered by such Resale
Shelf, (B) the date all of the Purchaser’s Registrable Securities covered by the Resale Shelf can be sold publicly without restriction or limitation under Rule 144 under the Securities Act and without the requirement to be in compliance
with Rule 144(c)(1) under the Securities Act; and provided, further, with respect to Registrable Securities acquired after the Business Combination Closing, the Company shall only be obligated to amend the Resale Shelf or file a new
registration statement that will constitute a Resale Shelf to include such Registrable Securities on two (2) occasions, each upon the written request of Purchaser with respect to at least 100,000 Registrable Securities. 

2. In the event the Company is prohibited by applicable rule, regulation or interpretation by the staff (“Staff’) of the
Securities and Exchange Commission (“SEC”) from registering all of the Registrable Securities on the Resale Shelf or the Staff requires that the Purchaser be specifically identified as an “underwriter” in order to permit
such registration statement to become effective, and such Purchaser does not consent in writing to being so named as an underwriter in such registration statement, the number of Registrable Securities to be registered on the Resale Shelf will be
reduced on a pro rata basis among all the holders of Registrable Securities to be so included, unless otherwise required by the Staff, so that the number of Registrable Securities to be registered is permitted by Staff and such Purchaser is not
required to be named as an “underwriter”; provided, that any Registrable Securities not registered due to this paragraph 2 shall thereafter as soon as allowed by the SEC guidance be registered to the extent the prohibition no longer
is applicable. 
 3. If at any time the Company proposes to file a registration statement (a “Registration Statement”) on
its own behalf, or on behalf of any other Persons who have registration rights (“Other Holders”), relating to an underwritten offering of ordinary shares, or engage in an Underwritten Shelf Takedown (as defined below) off an
existing registration statement (a 

  
 A - 1 

 
“Company Offering”), then the Company will provide the Purchaser and each other Forward Contract Party who purchased at least 1,000,000 Forward Purchase Shares (collectively, the
“Piggyback Holders”) with notice in writing (an “Offer Notice”) at least five (5) Business Days prior to such filing, which Offer Notice will offer to include in the Registration Statement Purchaser’s
Registrable Securities and a minimum of 500,000 of the securities of each other Forward Contract Party which is a Piggyback Holder that constitute “Registrable Securities” under such parties’ forward purchase agreements (collectively
“Piggyback Securities”). Within five (5) Business Days (or, in the case of an Offer Notice delivered to the Purchaser or the other Forward Contract Parties in connection with an Underwritten Shelf Takedown, within three
(3) Business Days) after receiving the Offer Notice, the Purchaser may make a written request (a “Piggyback Request”) to the Company to include some or all of Purchaser’s Registrable Securities in the Registration
Statement. If the underwriter(s) for any Company Offering advise the Company that marketing factors require a limitation on the number of securities that may be included in the Company Offering, the number of securities to be so included shall be
allocated as follows: (i) first, to the Company and the Other Holders, if any; and (ii) second, to the Piggyback Holders based on the pro rata percentage of Piggyback Securities held by the Piggyback Holders and requested to be
included in the Underwritten Offering. Notwithstanding anything to the contrary in this paragraph 3, the Company hereby agrees that it will not provide an Offer Notice to any other Forward Contract Party unless such other Forward Contract Party
agrees in writing to treat the contents of such Offer Notice as material non-public information. 

4. At any time during which the Company has an effective Resale Shelf with respect to the Purchaser’s Registrable Securities, the
Purchaser may make a written request (which request shall specify the intended method of disposition thereof) (a “Shelf Takedown Request”) to the Company to effect a sale, of all or a portion of the Purchaser’s Registrable
Securities that are covered by the Resale Shelf, and the Company shall use commercially reasonable efforts to file, to the extent required by applicable law or regulation, a prospectus supplement (a “Shelf Takedown Prospectus
Supplement”) for such purpose as soon as reasonably practicable following receipt of a Shelf Takedown Request. The Purchaser may request that any such sale be conducted as an underwritten public offering (an “Underwritten Shelf
Takedown”). The Company shall not be obligated to effect more than two Underwritten Shelf Takedowns. The Purchaser acknowledges that, pursuant to the terms and conditions of Forward Contracts among the Company and other Forward Contract
Parties (such agreements, as they relate to the rights of the other Forward Contract Parties set forth in paragraphs 3, 4 and 5 of this Exhibit A, not to be amended without the Purchaser’s prior written consent), each other Forward Contract
Party who purchased at least 1,000,000 Forward Purchase Shares and proposes to sell at least 500,000 Registrable Securities in the Underwritten Shelf Takedown (a “Requesting Holder”) shall have the right, pursuant to a timely
Piggyback Request, to include securities that are covered by the Resale Shelf (“Requesting Holder Securities”) in the prospectus supplement relating to any Underwritten Shelf Takedown and the Purchaser agrees to cooperate with the
Company and such other Forward Contract Parties in furtherance thereof. If the underwriter(s) for any Underwritten Shelf Takedown advise the Company that marketing factors require a limitation on the number of securities that may be included in the
Underwritten Shelf Takedown, the number of securities to be so included shall be allocated as follows: (i) first, to the Purchaser; and (ii) second, to the Requesting Holders based on the pro rata percentage of Requesting Holder
Securities held by the Requesting Holders and requested to be included in the Underwritten Offering. It is understood that any other Forward Contract Party electing to include securities on an 

  
 A - 2 

 
Underwritten Shelf Takedown proposed by Purchaser shall not have the ability to withdraw such securities from such offering without the consent of the Purchaser, it being understood that the
terms of the offering may not be known at the time of such offering and that Purchaser shall have the sole discretion to approve such terms (and such other Forward Contract Party shall not have the right to make any determinations other than whether
they wish to include their Requesting Holder Securities in the prospectus supplement). In this regard, by electing to include securities in such offering, such other Forward Contract Party agrees to cooperate with the Company and the Purchaser in
furtherance of such offering, including entering into such customary agreements and take all such actions (including supplying all reasonably requested information) within 48 hours of a reasonable request by the Company, underwriters or Purchaser.

 5. The determination of whether any offering of Registrable Securities pursuant to the Resale Shelf or a Shelf Takedown Prospectus
Supplement will be an underwritten offering shall be made in the sole discretion of the Purchaser, after consultation with the Company, and the Purchaser shall have the right, after consultation with the Company, to determine the plan of
distribution, including the price at which the Registrable Securities are to be sold and the underwriting commissions, discounts and fees (and the Piggyback Holders or Requesting Holders (as applicable) shall not have the right to make any
determinations other than whether they wish to include their Requesting Holder Securities in the prospectus supplement). The Purchaser shall select the investment banker or bankers and managers to administer the offering, including the lead managing
underwriter (provided that such investment banker or bankers and managers shall be reasonably satisfactory to the Company). 
 6. In
connection with any underwritten offering, the Company shall enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Purchaser) in order to facilitate the disposition of such
Registrable Securities as are reasonably necessary or required, and in such connection enter into a customary underwriting agreement that provides for customary opinions, comfort letters and officer’s certificates and other customary
deliverables. 
 7. The Company shall pay all fees and expenses incident to the performance of or compliance with its obligation to prepare,
file and maintain the Resale Shelf (including the fees of its counsel and accountants). The Company shall also pay all Registration Expenses. For purposes of this paragraph 7, “Registration Expenses” shall mean the out-of-pocket expenses of a Company Offering or an Underwritten Shelf Takedown, including, without limitation, the following: (i) all registration and filing fees
(including fees with respect to filings required to be made with FINRA) and any securities exchange on which the Registrable Securities are then listed; (ii) fees and expenses of compliance with securities or blue sky laws (including reasonable
fees and disbursements of one counsel to the underwriters in connection with blue sky qualifications of the Registrable Securities); (iii) printing, messenger, telephone and delivery expenses; (iv) reasonable fees and disbursements of counsel
for the Company; (v) reasonable fees and disbursements of all independent registered public accountants of the Company incurred specifically in connection with such Underwritten Shelf Takedown; and (vi) reasonable fees and expenses of one
legal counsel selected by the Purchaser; provided, that it is understood and agreed that the Company shall not be responsible for any underwriting fees, discounts, selling commissions, underwriter expenses and stock transfer taxes relating to
the registration and sale of the Purchaser’s Registrable Securities. 

  
 A - 3 

 8. The Company may suspend the use of a prospectus included in the Resale Shelf by
furnishing to the Purchaser a written notice (“Suspension Notice”) stating that in the good faith judgment of the Company, it would be either (i) prohibited by the Company’s insider trading policy (as if the Purchaser were
covered by such policy) or (ii) materially detrimental to the Company and its shareholders for such prospectus to be used at such time. The Company’s right to suspend the use of such prospectus under clause (ii) of the preceding
sentence may be exercised for a period of not more than sixty (60) days after the date of such notice to the Purchaser; provided such period may be extended for an additional thirty (30) days with the consent of a majority-in-interest of the holders of Registrable Securities covered by the Resale Shelf; provided further, that such right to suspend the use of a prospectus shall be
exercised by the Company not more than once in any twelve (12) month period. A holder of Registrable Securities shall not effect any sales of Registrable Securities pursuant to the Resale Shelf at any time after it has received a Suspension
Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). The holders may recommence effecting sales of the Registrable Securities pursuant to the Resale Shelf following further written notice to such effect (an
“End of Suspension Notice”) from the Company to the holders. The Company shall act in good faith to permit any suspension period contemplated by this paragraph to be concluded as promptly as reasonably practicable. 

9. The Purchaser agrees that, except as required by applicable law, the Purchaser shall treat as confidential the receipt of any Suspension
Notice (provided that in no event shall such notice contain any material nonpublic information of the Company) hereunder and shall not disclose or use the information contained in such Suspension Notice without the prior written consent of the
Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by a holder of Registrable Securities in breach of the terms of this Agreement. 

10. The Company shall indemnify and hold harmless the Purchaser, its directors and officers, partners, members, managers, employees, agents,
and representatives of such Purchaser and each person, if any, who controls the Purchaser within the meaning of the Securities Act and the Securities Exchange Act of 1934, as amended, and any agent thereof (collectively, “Indemnified
Persons”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses,
judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved,
or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), promptly as incurred, arising out of, based upon or resulting from any untrue statement or alleged untrue
statement of any material fact contained in the Resale Shelf (or any amendment or supplement thereto), the related prospectus, or any amendment or supplement thereto, or arise out of, are based upon or resulting from the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable in any such
case or to any Indemnified Person to the extent that any such Loss arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission or so made in reliance upon or in conformity with
information furnished by or on behalf of such Indemnified 

  
 A - 4 

 
Person in writing specifically for use in the preparation of the Resale Shelf, the related prospectus, or any amendment or supplement thereto. Such indemnity shall remain in full force and effect
regardless of any investigation made by or on behalf of such Indemnified Person, and shall survive the transfer of such securities by the Purchaser. 

11. The Company’s obligation under paragraph (1) of this Exhibit A is subject to the Purchaser’s furnishing to the Company in
writing such information as the Company reasonably requests for use in connection with the Resale Shelf, the related prospectus, or any amendment or supplement thereto. The Purchaser shall indemnify the Company, its officers, directors, managers,
employees, agents and representatives, and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from any untrue statement or alleged untrue statement
of material fact contained in the Resale Shelf, the related prospectus, or any amendment or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or necessary to make the statements therein not
misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished in writing by such Purchaser expressly for inclusion in such document; provided that the obligation to indemnify shall be
individual, not joint and several, for each Purchaser and shall be limited to the net amount of proceeds received by such Purchaser from the sale of Registrable Securities pursuant to the Resale Shelf. 

12. The Company shall cooperate with the Purchaser, to the extent the Registrable Securities become freely tradable, to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Resale Shelf and enable such certificates to be in such denominations or amounts, as the case may be,
as the Purchaser may reasonably request and registered in such names as the Purchaser may request. 
 13. If requested by the Purchaser, the
Company shall as soon as practicable, subject to any Suspension Notice, (i) incorporate in a prospectus supplement or post-effective amendment such information as the Purchaser reasonably requests to be included therein relating to the sale and
distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the
Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably requested by the Purchaser holding any Registrable Securities. 

14. As long as the Purchaser shall own Registrable Securities, the Company, at all times while it shall be reporting under the Securities
Exchange Act of 1934, as amended, shall file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of
the Securities Exchange Act of 1934, as amended, and shall promptly furnish the Purchaser with true and complete copies of all such filings, unless filed through the SEC’s EDGAR system. The Company further covenants that it shall take such
further action as the Purchaser may reasonably request, all to the extent required from time to time, to enable the Purchaser to sell the Class A Shares and Warrants held by the Purchaser without registration

  
 A - 5 

 
under the Securities Act within the limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions. Upon the request of the
Purchaser, the Company shall deliver to the Purchaser a written certification of a duly authorized officer as to whether it has complied with such requirements. 

15. The rights, duties and obligations of the Purchaser under this Exhibit A may be assigned or delegated by the Purchaser in conjunction with
and to the extent of any transfer or assignment of Registrable Securities by the Purchaser to any transferee or assignee.

 Recitals 

WHEREAS, the Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization
or similar business combination with one or more businesses (a “Business Combination”); 
 WHEREAS, the Company has
confidentially submitted to the U.S. Securities and Exchange Commission (the “SEC”) a draft registration statement on Form S-1 (the “Registration Statement”) for its initial
public offering (“IPO”) of 20,000,000 units (or 23,000,000 units in the aggregate if the underwriter’s over-allotment is exercised in full) (the “Public Units”) at a price of $10.00 per Public Unit, each
comprised of one Class A ordinary share of the Company, par value $0.0001 per share (the “Class A Share(s)”), and one-half of one redeemable warrant, where each whole
redeemable warrant is exercisable to purchase one Class A Share at an exercise price of $11.50 per share (the “Warrant(s)”); 

WHEREAS, following the closing of the IPO (the “IPO Closing”), the Company will seek to identify and consummate a Business
Combination; 
 WHEREAS, the parties wish to enter into this Agreement, pursuant to which (i) immediately prior to the closing of the
Company’s initial Business Combination (the “Business Combination Closing”), the Company shall issue and sell, and the Purchaser shall purchase, on a private placement basis, the number of Class A Shares determined
pursuant to Section 1(a)(i) hereof (the “Forward Purchase Shares”) and the applicable number of Warrants determined pursuant to Section 1(a)(i) hereof, with one Warrant being issuable to the Purchaser per each increment of
four (4) Forward Purchase Shares actually issued and sold to the Purchaser hereunder (the “Forward Purchase Warrant(s)” and together with the Forward Purchase Shares, the “Forward Purchase Units”) and
(ii) concurrently herewith, the Sponsor will transfer to the Purchaser, on a private placement basis, Class B ordinary shares of the Company, par value $0.0001 per share (the “Class B Share(s)”), in an
amount equal to the Class B Shares Transfer Amount determined pursuant to Section 1(b) hereof, in each case on the terms and conditions set forth herein; 

WHEREAS, the Class B Shares are automatically convertible into Class A Shares following the Business Combination Closing on the
terms and conditions set forth in the Company’s memorandum and articles of association, as it may be amended from time to time (the “Charter”); and 

 WHEREAS, the Company has entered, or intends concurrently with this entry into this
Agreement to enter, into one or more agreements (collectively, the “Forward Contracts”) substantially in the form of this Agreement with other third parties (together with the Purchaser, the “Forward Contract
Parties” and each, a “Forward Contract Party”) for the purchase of Class A Shares and Warrants upon the Business Combination Closing (all Class A Shares to be purchased pursuant to such Forward Contracts, together
with the Forward Purchase Shares, collectively, the “Total Forward Purchase Shares”), and for the transfer by the Sponsor to such third parties of Class B Shares upon execution of such Forward Contracts. 

NOW, THEREFORE, in consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for
other good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows: 

Agreement 
 1. Sale and
Purchase. 
 (a) Forward Purchase Units. 

(i) The Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, the number of Forward Purchase
Shares set forth on the signature page to this Agreement next to the line item “Number of Forward Purchase Shares,” plus the number of Forward Purchase Warrants set forth on the signature page to this Agreement next to the line item
“Number of Forward Purchase Warrants,” for an aggregate purchase price of $10.00 multiplied by the number of Forward Purchase Units issued and sold hereunder (the “FPU Purchase Price”). No fractional Forward Purchase
Warrants will be issued. 
 (ii) Each Forward Purchase Warrant will have the same terms as each Warrant sold as part of the Public Units in
the IPO (“Public Warrants”) and will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock Transfer & Trust Company, as Warrant Agent, in connection
with the IPO (the “Warrant Agreement”). Each Forward Purchase Warrant will entitle the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement,
and only whole Forward Purchase Warrants will be exercisable. The Forward Purchase Warrants will become exercisable on the later of thirty (30) days after the Business Combination Closing and twelve (12) months from the IPO Closing, and
will expire at 5:00 p.m., New York City time, five (5) years after the Business Combination Closing or earlier upon redemption or the liquidation of the Company, as described in the Warrant Agreement. 

(iii) The Company shall require the Purchaser to purchase the Forward Purchase Shares and the Forward Purchase Warrants pursuant to
Section 1(a)(i) hereof by delivering notice to the Purchaser, at least ten (10) Business Days before the funding of the FPU Purchase Price to the Escrow Account (as defined below), specifying the number of Forward Purchase Shares and
Forward Purchase Warrants the Purchaser is required to purchase, the anticipated date of the Business Combination Closing, the aggregate FPU Purchase Price and instructions for wiring the FPU Purchase Price to an account of a third-party escrow
agent (the “Escrow Account”), which shall be the Company’s transfer agent (the “Escrow Agent”), pursuant to an escrow agreement between the Company and the Escrow Agent (the “Escrow 

  
 2 

 
Agreement”). At least two (2) Business Days before the anticipated date of the Business Combination Closing specified in such notice, the Purchaser shall deliver the FPU Purchase
Price in cash via wire transfer to the account specified in such notice, to be held in escrow pending the Business Combination Closing. If the Business Combination Closing does not occur within thirty (30) days after the Purchaser delivers the
FPU Purchase Price to the Escrow Agent, the Escrow Agreement will provide that the Escrow Agent shall automatically return to the Purchaser the FPU Purchase Price, provided that the return of the FPU Purchase Price placed in escrow shall not
terminate the Agreement or otherwise relieve either party of any of its obligations hereunder. For the purposes of this Agreement, “Business Day” means any day, other than a Saturday or a Sunday, that is neither a legal holiday nor a day
on which banking institutions are generally authorized or required by law or regulation to close in the City of New York, New York, or Hong Kong. 

(iv) The closing of the sale of the Forward Purchase Units (the “FPU Closing”) shall be held on the same date and immediately
prior to the Business Combination Closing (such date being referred to as the “Closing Date”). At the FPU Closing, the Company will issue to the Purchaser the Forward Purchase Units, each registered in the name of the Purchaser,
against (and concurrently with) release of the FPU Purchase Price by the Escrow Agent to the Company. 
 (b) Class B Shares. In
consideration of the Purchaser’s agreement to purchase Forward Purchase Units, the Sponsor shall transfer to the Purchaser the number of Class B Shares set forth in Schedule A to this Agreement next to the line item “Class B
Shares Transfer Amount,” which shall be calculated in accordance with the definition of Class B Shares Transfer Amount set forth in Schedule A to this Agreement. The Class B Shares received by the Purchaser hereunder are subject to
forfeiture in accordance with Section 5(b) hereof. The transfer of the Class B Shares (the “Class B Share Transfer”) to the Purchaser shall take place concurrently with the execution of this Agreement.

 (c) Delivery of Securities. 

(i) The Company shall register the Purchaser as the owner of the Forward Purchase Units purchased, and the Class B Shares received, by
the Purchaser hereunder (individually or collectively, the “Securities”) in the register of members of the Company and with the Company’s transfer agent by book entry on or promptly after (but in no event more than two
(2) Business Days after) the date of the FPU Closing and the Class B Share Transfer, respectively. 
 (ii) Each register and book
entry for the Securities shall contain a notation, and each certificate (if any) evidencing the Securities shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES
LAWS OF ANY STATE OR OTHER JURISDICTION, AND MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.” 

  
 3 

 (iii) Each register and book entry for the Class B Shares transferred to the Purchaser
shall contain a notation, and each certificate (if any) evidencing such Class B Shares shall be stamped or otherwise imprinted with a legend, in substantially the following form: 

“THE SALE, PLEDGE, HYPOTHECATION, OR TRANSFER OF THE SECURITIES REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN
FORWARD PURCHASE AGREEMENT BY AND AMONG THE HOLDER AND THE OTHER PARTIES THERETO. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.” 

(d) Legend Removal. Following the expiration of the transfer restrictions set forth in Section 5(a), if the Securities are eligible
to be sold without restriction under, and without the Company being in compliance with the current public information requirements of, Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”), or there is an
effective registration statement covering the resale of the Securities (and the Purchaser provides the Company with a written undertaking to sell its Securities only in accordance with the plan of distribution contained in such registration
statement and only if such Purchaser has not been informed that the prospectus in such registration statement is not current or the registration statement is no longer effective), then at the Purchaser’s request, the Company will cause the
Company’s transfer agent to remove the legend set forth in Section 1(c)(ii) and Section 1(c)(iii). In connection therewith, if required by the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be
delivered to and maintained with its transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and direct the transfer agent to transfer such Securities without any such legend;
provided, that, notwithstanding the foregoing, the Company will not be required to deliver any such opinion, authorization, certificate or direction if it reasonably believes that removal of the legend could result in or facilitate transfers of
Securities in violation of applicable law. 
 (e) Registration Rights. The Purchaser shall have registration rights as set forth on
Exhibit A (the “Registration Rights”). 
 2. Representations and Warranties of the Purchaser. The
Purchaser represents and warrants to the Company as follows, as of the date hereof: 
 (a) Organization and Power. If an entity, the
Purchaser is duly organized, validly existing, and in good standing under the laws of the jurisdiction of its formation (if the concept of “good standing” is a recognized concept in such jurisdiction) and has all requisite power and
authority to carry on its business as presently conducted and as proposed to be conducted. 
 (b) Authorization. The Purchaser has
full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute the valid and legally binding obligation of the Purchaser, enforceable in accordance with its terms, except
(i) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable remedies, or (iii) to the extent the indemnification provisions contained in the Registration Rights may be limited by applicable federal or state securities laws.

  
 4 

 (c) Governmental Consents and Filings. No consent, approval, order or authorization
of, or registration, qualification, designation, declaration or filing with, any federal, state or local governmental authority is required on the part of the Purchaser in connection with the consummation of the transactions contemplated by this
Agreement. 
 (d) Compliance with Other Instruments. The execution, delivery and performance by the Purchaser of this Agreement and
the consummation by the Purchaser of the transactions contemplated by this Agreement will not result in any violation or default (i) of any provisions of its organizational documents, if applicable, (ii) of any instrument, judgment, order,
writ or decree to which it is a party or by which it is bound, (iii) under any note, indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to which it is a party
or by which it is bound or (v) of any provision of federal or state statute, rule or regulation applicable to the Purchaser, in each case (other than clause (i)), which would have a material adverse effect on the Purchaser or its ability to
consummate the transactions contemplated by this Agreement. 
 (e) Purchase Entirely for Own Account. This Agreement is made with the
Purchaser in reliance upon the Purchaser’s representation to the Company, which by the Purchaser’s execution of this Agreement, the Purchaser hereby confirms, that the Securities to be acquired by the Purchaser will be acquired for
investment for the Purchaser’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation in, or
otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser does not presently have any contract, undertaking, agreement or arrangement with any Person to sell, transfer or
grant participations to such Person or to any third Person, with respect to any of the Securities. If the Purchaser was formed for the specific purpose of acquiring the Securities, each of its equity owners is an accredited investor as defined in
Rule 501(a) of Regulation D promulgated under the Securities Act. For purposes of this Agreement, “Person” means an individual, a limited liability company, a partnership, a joint venture, a corporation, a trust, an unincorporated
organization, any other entity or any government or any department or agency thereof. 
 (f) Disclosure of Information. The Purchaser

not be able to satisfy. The Purchaser acknowledges that the Company confidentially submitted the Registration Statement for its proposed IPO to the SEC for review. The Purchaser understands that the offering to the Purchaser of the Securities is

the purchase, holding, redemption, sale, or transfer of the Securities. The Purchaser’s subscription and payment for and continued beneficial ownership of the Securities will not violate any applicable securities or other laws of the
Purchaser’s jurisdiction.

 4A. Right of First Offer.
Subject to the terms and conditions of this Section, if, in connection with or prior to the Business Combination Closing, the Company proposes to raise additional capital by issuing any equity securities, or securities convertible into, exchangeable
or exercisable for equity securities, other than the Public Units (and their component Class A Shares, Public Warrants and the Class A Shares underlying the Public Warrants) and Excluded Securities (as defined below) (“New Equity
Securities”), the Company shall first make an offer of the applicable pro rata portion of New Equity Securities to the Purchaser, which portion will be determined by dividing (a) the FPU Purchase Price to be paid by
the Purchaser at the FPU Closing, by (b) the sum of the total proceeds raised in the IPO and the total FPU Purchase Price to be paid by all Forward Contract Parties at the FPU Closing. 

(a) Offer Notice. 

(i) The Company shall give written notice (the “Offering Notice”) to the Purchaser and the other Forward Contract
Parties stating its bona fide intention to offer the New Equity Securities and specifying the number of New Equity Securities and the material terms and conditions, including the price, pursuant to which the Company proposes to offer the New Equity
Securities and the applicable pro rata portion of such New Equity Securities offered to the Purchaser. 
 (ii) The
Offering Notice shall constitute the Company’s offer to sell the applicable pro rata portion of New Equity Securities to the Purchaser and the other Forward Contract Parties, which offer shall be irrevocable for a period of
five (5) Business Days (the “ROFO Notice Period”). 
 (b) Exercise of Right of First Offer. 

(i) Upon receipt of the Offering Notice, the Purchaser shall have, until the end of the ROFO Notice Period, the right (but not the
obligation) to offer to purchase all or a portion of its pro rata portion of the New Equity Securities, by delivering a written notice (a “ROFO Offer Notice”) to the Company stating that it offers to purchase such
New Equity Securities on the terms specified in the Offering Notice. Any ROFO Offer Notice so delivered shall be binding upon delivery and irrevocable by the Purchaser. 

  
 11 

 (ii) If the Purchaser does not deliver a ROFO Offer Notice during the ROFO Notice
Period, the Purchaser shall be deemed to have waived all of the Purchaser’s rights to purchase the New Equity Securities offered pursuant to the Offering Notice under this Section, and the Company shall thereafter be free to sell or enter into
an agreement to sell the Purchaser’s pro rata portion of such New Equity Securities to any third party (including any Forward Contract Parties) without any further obligation to the Purchaser pursuant to this Section within the
ninety (90) day period thereafter (and with respect to an agreement to sell, consummate such sale at any time thereafter) on terms and conditions not more favorable to the third party than those set forth in the Offering Notice. If the Company
does not sell or enter into an agreement to sell the Purchaser’s pro rata portion of the New Equity Securities within such period, the rights provided hereunder shall be deemed to be revived and the New Equity Securities shall
not be offered to any third party unless first re-offered to the Purchaser in accordance with this Section. 

(c) Excluded Securities. For purposes hereof, the term “Excluded Securities” means Class B Shares (and
Class A Shares into which such Class B Shares are convertible) issued to the Sponsor prior to the IPO, the private placement warrants sold to the Sponsor or its affiliates in connection with the IPO (the “Private Placement
Warrants”), warrants issued upon the conversion of working capital loans to the Company to be made by the Sponsor or an affiliate thereof to finance transaction costs in connection with an intended initial Business Combination (up to
$1,500,000 of which may be convertible at the option of the lender into warrants of the post-Business Combination entity having the same terms as the Private Placement Warrants at a price of $1.00 per warrant), any securities issued by the Company
as consideration to any seller in the Business Combination, and any Class A Shares, Class B Shares (and Class A Shares into which such Class B Shares are convertible) and Forward Purchase Warrants issued pursuant to forward
purchase contracts entered into prior to the IPO Closing with Forward Contract Parties.

and Waivers of the Purchaser. 
 (a) Lock-up; Transfer Restrictions. The Purchaser agrees
that it shall not Transfer (as defined below) any Class B Shares owned by it and the Class A Shares into which such Class B Shares are convertible, until the earlier of (A) one year after the Business Combination Closing and
(B) the date following the Business Combination Closing on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Company’s ordinary shareholders having the right to
exchange their ordinary shares of the Company for cash, securities or other property. Notwithstanding the foregoing, if, subsequent to a Business Combination, the closing price of the Class A Shares equals or exceeds $12.00 per share (as
adjusted for share sub-divisions, share capitalization, 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 Business Combination Closing, the Class B Shares (and the Class A Shares into which the Class B Shares are convertible) shall be released from the lockup referred to in this
Section 5(a). Notwithstanding the first sentence hereinabove, Transfers of the Class B Shares (and the Class A Shares into which the Class B Shares are convertible) are permitted (i) to the Company’s officers or
directors, any affiliates or family members of any of the Company’s officers or directors, any 

  
 12 

 
members or partners of the Sponsor or their affiliates, any affiliates of the Sponsor, or any employees of such affiliates; (ii) 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, an affiliate of such person or to a charitable organization; (iii) in the case of an individual, by virtue of laws
of descent and distribution upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers made in connection with the consummation of a Business
Combination at prices no greater than the price at which the Class B Shares were originally purchased; (vi) by virtue of the Purchaser’s organizational documents upon liquidation or dissolution of the Purchaser; (vii) in the
event of the Company’s liquidation prior to the completion of a Business Combination; or (viii) in the event of the Company’s completion of 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 Shares for cash, securities or other property subsequent to the completion of a Business Combination; provided, however, that in the case of clauses (i) through (vi)
these permitted transferees must enter into a written agreement agreeing to be bound by these transfer restrictions. As used in this Agreement, “Transfer” shall mean the (x) sale of, offer to sell, contract or agreement to
sell, hypothecation, 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 or liquidation with respect to or decrease of a call
equivalent position (within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”, and the rules and regulations of the SEC promulgated thereunder) with respect to, any of the
Securities (excluding any pledges in the ordinary course of business for bona fide financing purposes or as part of prime brokerage arrangements), (y) entry into any swap or other arrangement that transfers to another, in whole or in part, any of
the economic consequences of ownership of any of the Securities, whether any such transaction is to be settled by delivery of such Securities, in cash or otherwise, or (z) public announcement of any intention to effect any transaction specified
in clause (x) or (y). For the avoidance of doubt, this Section 5(a) shall not restrict the ability to exercise any Forward Purchase Warrants in accordance with their terms. For the further avoidance of doubt, “Transfer” does not
include any transfer of such Class B Shares (and the Class A Shares into which the Class B Shares are convertible) among any of the investment funds or managed accounts managed by the Purchaser. 

(b) Potential Forfeiture. The Purchaser agrees that, to the extent that it fails to pay the FPU Purchase Price when required in
accordance with Section 1 hereof and such failure to pay remains uncured after five (5) Business Days’ notice from the Company, the Purchaser shall forfeit to the Company all of its Class B Shares. If the Purchaser fails to
forfeit any Class B Shares it is required to forfeit hereunder, the Purchaser hereby grants hereunder to the Company and any representative designated by the Company without further action by the Purchaser a limited irrevocable power of
attorney to effect such forfeiture on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest. Any forfeiture under this Agreement shall take effect as a surrender for no consideration as a matter of Cayman
Islands law. 

  
 13 

 (c) Waiver of Adjustment to Conversion Price and Recapitalization Shares. In the
event that the Company issues equity or equity-linked securities in addition to the Forward Purchase Units in connection with the Business Combination Closing and the Sponsor waives, in whole or in part, its right to have its Class B Shares
converted into a greater number of Class A Shares in respect of such issuance pursuant to the Charter, such waiver shall also automatically waive such right on behalf of the Purchaser in respect of the Purchaser’s Class B Shares on a
pro rata basis. In addition, the Purchaser: (i) agrees that it waives its right to receive any additional Class B Shares in the event of any share split, share capitalization, reorganization or recapitalization of or in respect of the
Class B Shares prior to the IPO Closing that is effected in order to increase the number of issued and outstanding Class B Shares due to an increase in the number of Class A Shares being sold in the IPO (“Share
Capitalization”); (ii) directs the Company to issue its portion of a Share Capitalization to the Sponsor; and (iii) confirms that it has no claims against the Company, or its directors, officers, employees or other shareholders in respect
of a Share Capitalization. 
 (d) Trust Account. 

(i) The Purchaser hereby acknowledges that it is aware that the Company will establish a trust account (the “Trust Account”)
for the benefit of its public shareholders upon the IPO Closing. The Purchaser, for itself and its affiliates, hereby agrees that it 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, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Class A Shares issued in the IPO (the “Public Shares”) held by it.

 (ii) The Purchaser hereby agrees that it shall have no right of set-off or any right, title,
interest or claim of any kind (“Claim”) to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it may have now or in the future, except for redemption and
liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser shall pursue such Claim solely against the Company and
its assets outside the Trust Account and not against the property or any monies in the Trust Account, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it. 

(e) Redemption and Liquidation. The Purchaser hereby waives, with respect to any Class B Shares (including the Class A Shares
into which such Class B Shares are convertible) held by it, any redemption rights it may have in connection with (i) the consummation of a Business Combination, including any such rights available in the context of a shareholder vote to
approve such Business Combination and (ii) any shareholder vote to approve an amendment to the Charter that would affect the substance or timing of the Company’s obligation to redeem 100% of the Class A Shares sold in the IPO if the
Company has not consummated an initial Business Combination within the time period set forth in the Charter or in the context of a tender offer made by the Company to purchase Class A Shares, it being understood that the Purchaser shall be
entitled to redemption and liquidation rights with respect to any Public Shares beneficially owned by it. 

  
 14 

 (f) Voting. The Purchaser hereby agrees that if the Company seeks shareholder
approval of a proposed Business Combination, then in connection with such proposed Business Combination, the Purchaser shall vote any Class B Shares and Class A Shares owned by it in favor of any proposed Business Combination. If the
Purchaser fails to vote any Class B Shares or Class A Shares it is required to vote hereunder in favor of a Proposed Business Combination, the Purchaser hereby grants to the Company and any representative designated by the Company without
further action by the Purchaser a limited irrevocable power of attorney to effect such vote on behalf of the Purchaser, which power of attorney shall be deemed to be coupled with an interest. 

(g) No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any
understanding with it, will engage in any Short Sales with respect to securities of the Company prior to the Business Combination Closing. For purposes of this Section, “Short Sales” shall include, without limitation, all
“short sales” as defined in Rule 200 promulgated under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary course of business as part of prime brokerage
arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements (including on a total return basis), and sales and other transactions through non-U.S. broker dealers or foreign
regulated brokers.

other Person in connection with any proposed Business Combination) without the prior written consent of the Purchaser. 
 (e) Nasdaq
Listing. The Company will use commercially reasonable efforts to effect the listing of the Class A Shares and Warrants on Nasdaq (or another national securities exchange). 

(f) No Amendments to Charter. The Charter of the Company will be in substantially the same form of Exhibit B hereto and will not
be materially amended prior to the IPO Closing without the Purchaser’s prior written consent. 
 6A. Transfer. This
Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation to purchase the Forward Purchase Units) may be transferred or assigned, at any time and from time to time, in whole or in part, to
one or more third parties (each such transferee, a “Transferee”), subject to the prior written consent of the Company (not to be unreasonably denied, withheld or delayed). Upon any such assignment: 

(a) the applicable Transferee shall execute a signature page to this Agreement, substantially in the form of the Purchaser’s signature
page hereto (the “Joinder Agreement”), which shall reflect the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by such Transferee (the “Transferee Securities”), and, upon such
execution, such Transferee shall have all the same rights and obligations of the Purchaser hereunder with respect to the Transferee Securities, and references herein to the “Purchaser” shall be deemed to refer to and include any such
Transferee with respect to such Transferee and to its Transferee Securities; provided, that any representations, warranties, covenants and agreements of the Purchaser and any such Transferee shall be several and not joint and shall be made as to the
Purchaser or any such Transferee, as applicable, as to itself only; and 
 (b) upon a Transferee’s execution and delivery of a Joinder
Agreement, the number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the Purchaser hereunder shall be reduced by the total number of Forward Purchase Shares and Forward Purchase Warrants to be purchased by the applicable
Transferee pursuant to the applicable Joinder Agreement, which reduction shall be evidenced by the Purchaser and the Company amending the “Number of Forward Purchase Shares”, “Number of Forward Purchase

  
 16 

 
Warrants”, and “Aggregate Purchase Price for Forward Purchase Units” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Units, and the
Purchaser shall be fully and unconditionally released from its obligation to purchase such Transferee Securities hereunder. For the avoidance of doubt, this Agreement need not be amended and restated in its entirety, but only the Purchaser’s
signature page hereto need be so amended and updated and executed by each of the Purchaser and the Company upon the occurrence of any such transfer of Transferee Securities.

effect, without any liability on the part of the Purchaser or the Company and their respective directors, officers, employees, partners, managers, members, or shareholders and all rights and obligations of each party shall cease; provided,

 19 

 (e) Successors. All of the terms, agreements, covenants, representations, warranties,
and conditions of this Agreement are binding upon, and inure to the benefit of and are enforceable by, the parties hereto and their respective successors. Nothing in this Agreement, express or implied, is intended to confer upon any party other than
the parties hereto or their respective successors and assigns any rights, remedies, obligations or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. 

(f) Assignments. Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its
rights, interests, or obligations hereunder without the prior written approval of the other parties. 
 (g) Counterparts. This
Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute one and the same instrument. 

(h) Headings. The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the
meaning or interpretation of this Agreement. 
 (i) Governing Law. This Agreement, the entire relationship of the parties hereto, and
any dispute between the parties (whether grounded in contract, tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of Hong Kong.

(m) Severability. The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will
not affect the validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not
to be enforceable in accordance with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have the power to modify the provision in a manner consistent with its objectives such
that it is enforceable, and/or to delete specific words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced. 

  
 20 

 (n) Expenses. Each of the Company and the Purchaser will bear its own costs and
expenses incurred in connection with the preparation, execution and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of agents, representatives, financial advisors, legal
counsel and accountants. The Company shall be responsible for the fees of its transfer agent, stamp taxes and all of The Depository Trust Company’s fees associated with the issuance of the Securities and the securities issuable upon conversion
or exercise of the Securities. 
 (o) 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. Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated thereunder, unless the context requires
otherwise. 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 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. 
 (p) Waiver. No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder,
whether intentional or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way any rights arising because of any prior or subsequent occurrence. 

(q) Confidentiality. Except as may be required by law, regulation or applicable stock exchange listing requirements, unless and until
the transactions contemplated hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential and shall not publicly disclose the existence or terms of this Agreement.

 (r) Specific Performance. The Purchaser agrees that irreparable damage would occur in the event that any provision of this
Agreement was not performed by the Purchaser in accordance with the specific terms hereof or was otherwise breached, and that money damages or legal remedies would not be an adequate remedy for any such damages. Therefore, it is accordingly agreed
that the Company shall be entitled to enforce specifically the terms and provisions of this Agreement, or to enforce compliance with, the covenants and obligations of the Purchaser, in any arbitration proceeding, and may also seek preliminary
injunctive relief in aid of arbitration in any court of competent jurisdiction in addition to any other remedy to which the Company is entitled at law or in equity. 

  
 21 

 (s) Most Favored Nations. The Company hereby represents and warrants that as of
the date hereof, and covenants and agrees that after the date hereof, none of the agreements with other Forward Contract Parties or any other person for the purchase of Forward Purchase Units, includes or will include terms, rights or other benefits
that are more favorable, in any material respect, to such other Person than the terms, rights and benefits in favor of the Purchaser under this Agreement, and the Company will not amend any of the material terms, rights or benefits in, or waive any
material obligation under, any of the agreements with such other Person unless, in any such case, the Purchaser has been offered in writing the opportunity to concurrently receive the benefits of all such terms, rights and benefits or waiver. The
Purchaser shall notify the Company in writing, within ten (10) days after the date it has been offered the opportunity to receive the benefit of such terms, rights, benefits or waiver, of its election to receive any such term, right, benefit or
waiver so offered.

 Exhibit A 

Registration Rights 
 1.
Within thirty (30) days after the Business Combination Closing, the Company shall use reasonable best efforts (i) to file a registration statement on Form S-3 for a secondary offering (including any
successor registration statement covering the resale of the Registrable Securities a “Resale Shelf”) of (x) the Class A Shares and Warrants (and underlying Class A Shares) comprising the Forward Purchase Units and the
Class A Shares into which the Class B Shares are convertible, (y) any other Class A Shares and Warrants that may be acquired by the Purchaser after the date of this Agreement, including any time after the Business Combination
Closing and (z) any other equity security of the Company issued or issuable with respect to the securities referred to in clauses (x) and (y) by way of a share capitalization or share sub-division or
in connection with a combination of shares, recapitalization, merger, consolidation or reorganization (collectively, the “Registrable Securities”) pursuant to Rule 415 under the Securities Act; provided, that if Form S-3 is unavailable for such a registration, the Company shall register the resale of the Registrable Securities on another appropriate form and undertake to register the Registrable Securities on Form S-3 as soon as such form is available, (ii) to cause the Resale Shelf to be declared effective under the Securities Act promptly thereafter, but in no event later than sixty (60) days thereafter, and
(iii) to maintain the effectiveness of such Resale Shelf with respect to the Purchaser’s Registrable Securities until the earliest of (A) the date on which the Purchaser ceases to hold Registrable Securities covered by such Resale
Shelf, (B) the date all of the Purchaser’s Registrable Securities covered by the Resale Shelf can be sold publicly without restriction or limitation under Rule 144 under the Securities Act and without the requirement to be in compliance
with Rule 144(c)(1) under the Securities Act; and provided, further, with respect to Registrable Securities acquired after the Business Combination Closing, the Company shall only be obligated to amend the Resale Shelf or file a new
registration statement that will constitute a Resale Shelf to include such Registrable Securities on two (2) occasions, each upon the written request of Purchaser with respect to at least 100,000 Registrable Securities. 

2. In the event the Company is prohibited by applicable rule, regulation or interpretation by the staff (“Staff’) of the
Securities and Exchange Commission (“SEC”) from registering all of the Registrable Securities on the Resale Shelf or the Staff requires that the Purchaser be specifically identified as an “underwriter” in order to permit
such registration statement to become effective, and such Purchaser does not consent in writing to being so named as an underwriter in such registration statement, the number of Registrable Securities to be registered on the Resale Shelf will be
reduced on a pro rata basis among all the holders of Registrable Securities to be so included, unless otherwise required by the Staff, so that the number of Registrable Securities to be registered is permitted by Staff and such Purchaser is not
required to be named as an “underwriter”; provided, that any Registrable Securities not registered due to this paragraph 2 shall thereafter as soon as allowed by the SEC guidance be registered to the extent the prohibition no longer
is applicable. 
 3. If at any time the Company proposes to file a registration statement (a “Registration Statement”) on
its own behalf, or on behalf of any other Persons who have registration rights (“Other Holders”), relating to an underwritten offering of ordinary shares, or engage in an Underwritten Shelf Takedown (as defined below) off an
existing registration statement (a 

  
 A - 1 

 
“Company Offering”), then the Company will provide the Purchaser and each other Forward Contract Party who purchased at least 1,000,000 Forward Purchase Shares (collectively, the
“Piggyback Holders”) with notice in writing (an “Offer Notice”) at least five (5) Business Days prior to such filing, which Offer Notice will offer to include in the Registration Statement Purchaser’s
Registrable Securities and a minimum of 500,000 of the securities of each other Forward Contract Party which is a Piggyback Holder that constitute “Registrable Securities” under such parties’ forward purchase agreements (collectively
“Piggyback Securities”). Within five (5) Business Days (or, in the case of an Offer Notice delivered to the Purchaser or the other Forward Contract Parties in connection with an Underwritten Shelf Takedown, within three
(3) Business Days) after receiving the Offer Notice, the Purchaser may make a written request (a “Piggyback Request”) to the Company to include some or all of Purchaser’s Registrable Securities in the Registration
Statement. If the underwriter(s) for any Company Offering advise the Company that marketing factors require a limitation on the number of securities that may be included in the Company Offering, the number of securities to be so included shall be
allocated as follows: (i) first, to the Company and the Other Holders, if any; and (ii) second, to the Piggyback Holders based on the pro rata percentage of Piggyback Securities held by the Piggyback Holders and requested to be
included in the Underwritten Offering. Notwithstanding anything to the contrary in this paragraph 3, the Company hereby agrees that it will not provide an Offer Notice to any other Forward Contract Party unless such other Forward Contract Party
agrees in writing to treat the contents of such Offer Notice as material non-public information. 

4. At any time during which the Company has an effective Resale Shelf with respect to the Purchaser’s Registrable Securities, the
Purchaser may make a written request (which request shall specify the intended method of disposition thereof) (a “Shelf Takedown Request”) to the Company to effect a sale, of all or a portion of the Purchaser’s Registrable
Securities that are covered by the Resale Shelf, and the Company shall use commercially reasonable efforts to file, to the extent required by applicable law or regulation, a prospectus supplement (a “Shelf Takedown Prospectus
Supplement”) for such purpose as soon as reasonably practicable following receipt of a Shelf Takedown Request. The Purchaser may request that any such sale be conducted as an underwritten public offering (an “Underwritten Shelf
Takedown”). The Company shall not be obligated to effect more than two Underwritten Shelf Takedowns. The Purchaser acknowledges that, pursuant to the terms and conditions of Forward Contracts among the Company and other Forward Contract
Parties (such agreements, as they relate to the rights of the other Forward Contract Parties set forth in paragraphs 3, 4 and 5 of this Exhibit A, not to be amended without the Purchaser’s prior written consent), each other Forward Contract
Party who purchased at least 1,000,000 Forward Purchase Shares and proposes to sell at least 500,000 Registrable Securities in the Underwritten Shelf Takedown (a “Requesting Holder”) shall have the right, pursuant to a timely
Piggyback Request, to include securities that are covered by the Resale Shelf (“Requesting Holder Securities”) in the prospectus supplement relating to any Underwritten Shelf Takedown and the Purchaser agrees to cooperate with the
Company and such other Forward Contract Parties in furtherance thereof. If the underwriter(s) for any Underwritten Shelf Takedown advise the Company that marketing factors require a limitation on the number of securities that may be included in the
Underwritten Shelf Takedown, the number of securities to be so included shall be allocated as follows: (i) first, to the Purchaser; and (ii) second, to the Requesting Holders based on the pro rata percentage of Requesting Holder
Securities held by the Requesting Holders and requested to be included in the Underwritten Offering. It is understood that any other Forward Contract Party electing to include securities on an 

  
 A - 2 

 
Underwritten Shelf Takedown proposed by Purchaser shall not have the ability to withdraw such securities from such offering without the consent of the Purchaser, it being understood that the
terms of the offering may not be known at the time of such offering and that Purchaser shall have the sole discretion to approve such terms (and such other Forward Contract Party shall not have the right to make any determinations other than whether
they wish to include their Requesting Holder Securities in the prospectus supplement). In this regard, by electing to include securities in such offering, such other Forward Contract Party agrees to cooperate with the Company and the Purchaser in
furtherance of such offering, including entering into such customary agreements and take all such actions (including supplying all reasonably requested information) within 48 hours of a reasonable request by the Company, underwriters or Purchaser.

 5. The determination of whether any offering of Registrable Securities pursuant to the Resale Shelf or a Shelf Takedown Prospectus
Supplement will be an underwritten offering shall be made in the sole discretion of the Purchaser, after consultation with the Company, and the Purchaser shall have the right, after consultation with the Company, to determine the plan of
distribution, including the price at which the Registrable Securities are to be sold and the underwriting commissions, discounts and fees (and the Piggyback Holders or Requesting Holders (as applicable) shall not have the right to make any
determinations other than whether they wish to include their Requesting Holder Securities in the prospectus supplement). The Purchaser shall select the investment banker or bankers and managers to administer the offering, including the lead managing
underwriter (provided that such investment banker or bankers and managers shall be reasonably satisfactory to the Company). 
 6. In
connection with any underwritten offering, the Company shall enter into such customary agreements and take all such other actions in connection therewith (including those requested by the Purchaser) in order to facilitate the disposition of such
Registrable Securities as are reasonably necessary or required, and in such connection enter into a customary underwriting agreement that provides for customary opinions, comfort letters and officer’s certificates and other customary
deliverables. 
 7. The Company shall pay all fees and expenses incident to the performance of or compliance with its obligation to prepare,
file and maintain the Resale Shelf (including the fees of its counsel and accountants). The Company shall also pay all Registration Expenses. For purposes of this paragraph 7, “Registration Expenses” shall mean the out-of-pocket expenses of a Company Offering or an Underwritten Shelf Takedown, including, without limitation, the following: (i) all registration and filing fees
(including fees with respect to filings required to be made with FINRA) and any securities exchange on which the Registrable Securities are then listed; (ii) fees and expenses of compliance with securities or blue sky laws (including reasonable
fees and disbursements of one counsel to the underwriters in connection with blue sky qualifications of the Registrable Securities); (iii) printing, messenger, telephone and delivery expenses; (iv) reasonable fees and disbursements of counsel
for the Company; (v) reasonable fees and disbursements of all independent registered public accountants of the Company incurred specifically in connection with such Underwritten Shelf Takedown; and (vi) reasonable fees and expenses of one
legal counsel selected by the Purchaser; provided, that it is understood and agreed that the Company shall not be responsible for any underwriting fees, discounts, selling commissions, underwriter expenses and stock transfer taxes relating to
the registration and sale of the Purchaser’s Registrable Securities. 

  
 A - 3 

 8. The Company may suspend the use of a prospectus included in the Resale Shelf by
furnishing to the Purchaser a written notice (“Suspension Notice”) stating that in the good faith judgment of the Company, it would be either (i) prohibited by the Company’s insider trading policy (as if the Purchaser were
covered by such policy) or (ii) materially detrimental to the Company and its shareholders for such prospectus to be used at such time. The Company’s right to suspend the use of such prospectus under clause (ii) of the preceding
sentence may be exercised for a period of not more than sixty (60) days after the date of such notice to the Purchaser; provided such period may be extended for an additional thirty (30) days with the consent of a majority-in-interest of the holders of Registrable Securities covered by the Resale Shelf; provided further, that such right to suspend the use of a prospectus shall be
exercised by the Company not more than once in any twelve (12) month period. A holder of Registrable Securities shall not effect any sales of Registrable Securities pursuant to the Resale Shelf at any time after it has received a Suspension
Notice from the Company and prior to receipt of an End of Suspension Notice (as defined below). The holders may recommence effecting sales of the Registrable Securities pursuant to the Resale Shelf following further written notice to such effect (an
“End of Suspension Notice”) from the Company to the holders. The Company shall act in good faith to permit any suspension period contemplated by this paragraph to be concluded as promptly as reasonably practicable. 

9. The Purchaser agrees that, except as required by applicable law, the Purchaser shall treat as confidential the receipt of any Suspension
Notice (provided that in no event shall such notice contain any material nonpublic information of the Company) hereunder and shall not disclose or use the information contained in such Suspension Notice without the prior written consent of the
Company until such time as the information contained therein is or becomes public, other than as a result of disclosure by a holder of Registrable Securities in breach of the terms of this Agreement. 

10. The Company shall indemnify and hold harmless the Purchaser, its directors and officers, partners, members, managers, employees, agents,
and representatives of such Purchaser and each person, if any, who controls the Purchaser within the meaning of the Securities Act and the Securities Exchange Act of 1934, as amended, and any agent thereof (collectively, “Indemnified
Persons”), to the fullest extent permitted by applicable law, from and against any losses, claims, damages, liabilities, joint or several, costs (including reasonable costs of preparation and reasonable attorneys’ fees) and expenses,
judgments, fines, penalties, interest, settlements or other amounts arising from any and all claims, demands, actions, suits or proceedings, whether civil, criminal, administrative or investigative, in which any Indemnified Person may be involved,
or is threatened to be involved, as a party or otherwise, under the Securities Act or otherwise (collectively, “Losses”), promptly as incurred, arising out of, based upon or resulting from any untrue statement or alleged untrue
statement of any material fact contained in the Resale Shelf (or any amendment or supplement thereto), the related prospectus, or any amendment or supplement thereto, or arise out of, are based upon or resulting from the omission or alleged omission
to state therein a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances in which they were made, not misleading; provided, however, that the Company shall not be liable in any such
case or to any Indemnified Person to the extent that any such Loss arises out of, is based upon or results from an untrue statement or alleged untrue statement or omission or alleged omission or so made in reliance upon or in conformity with
information furnished by or on behalf of such Indemnified Person in writing specifically for use in the preparation of the Resale Shelf, the related prospectus, or any amendment or supplement thereto. Such indemnity shall remain in full force and
effect regardless of any investigation made by or on behalf of such Indemnified Person, and shall survive the transfer of such securities by the Purchaser.

 11. The Company’s obligation under paragraph (1) of this Exhibit A is subject to
the Purchaser’s furnishing to the Company in writing such information as the Company reasonably requests for use in connection with the Resale Shelf, the related prospectus, or any amendment or supplement thereto. The Purchaser shall indemnify
the Company, its officers, directors, managers, employees, agents and representatives, and each person who controls the Company (within the meaning of the Securities Act) against any losses, claims, damages, liabilities and expenses resulting from
any untrue statement or alleged untrue statement of material fact contained in the Resale Shelf, the related prospectus, or any amendment or supplement thereto or any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein not misleading, but only to the extent that such untrue statement or omission is contained in any information so furnished in writing by such Purchaser expressly for inclusion in such document; provided that
the obligation to indemnify shall be individual, not joint and several, for each Purchaser and shall be limited to the net amount of proceeds received by such Purchaser from the sale of Registrable Securities pursuant to the Resale Shelf. 

12. The Company shall cooperate with the Purchaser, to the extent the Registrable Securities become freely tradable, to facilitate the timely
preparation and delivery of certificates (not bearing any restrictive legend) representing the Registrable Securities to be offered pursuant to a Resale Shelf and enable such certificates to be in such denominations or amounts, as the case may be,
as the Purchaser may reasonably request and registered in such names as the Purchaser may request. 
 13. If requested by the Purchaser, the
Company shall as soon as practicable, subject to any Suspension Notice, (i) incorporate in a prospectus supplement or post-effective amendment such information as the Purchaser reasonably requests to be included therein relating to the sale and
distribution of Registrable Securities, including, without limitation, information with respect to the number of Registrable Securities being offered or sold, the purchase price being paid therefor and any other terms of the offering of the
Registrable Securities to be sold in such offering; (ii) make all required filings of such prospectus supplement or post-effective amendment after being notified of the matters to be incorporated in such prospectus supplement or post-effective
amendment; and (iii) supplement or make amendments to any Registration Statement if reasonably requested by the Purchaser holding any Registrable Securities. 

14. As long as the Purchaser shall own Registrable Securities, the Company, at all times while it shall be reporting under the Securities
Exchange Act of 1934, as amended, shall file timely (or obtain extensions in respect thereof and file within the applicable grace period) all reports required to be filed by the Company after the date hereof pursuant to Sections 13(a) or 15(d) of
the Securities Exchange Act of 1934, as amended, and shall promptly furnish the Purchaser with true and complete copies of all such filings, unless filed through the SEC’s EDGAR system. The Company further covenants that it shall take such
further action as the Purchaser may reasonably request, all to the extent required from time to time, to enable the Purchaser to sell the Class A Shares and Warrants held by the Purchaser without registration under the Securities Act within the
limitation of the exemptions provided by Rule 144 promulgated under the Securities Act, including providing any legal opinions. Upon the request of the Purchaser, the Company shall deliver to the Purchaser a written certification of a duly
authorized officer as to whether it has complied with such requirements. 

  
 A - 5 

 15. The rights, duties and obligations of the Purchaser under this Exhibit A may be assigned
or delegated by the Purchaser in conjunction with and to the extent of any transfer or assignment of Registrable Securities by the Purchaser to any transferee or assignee.
