for its initial public offering (“IPO”) of 15,000,000 Class A ordinary shares, par value $0.0001 per share (the “Class

NOW, THEREFORE, in consideration
of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and valuable consideration,

Agreement


 


1. Sale
and Purchase.


 


(a) Forward
Purchase Shares.


 


(i) The
Company shall issue and sell to the Purchasers, severally and not jointly, and the Purchasers shall purchase from the Company, at a price
of $10.00 per share, an aggregate of 2,500,000 Forward Purchase Shares for an aggregate purchase price of $25,000,000 (the “FPS
Purchase Price”), with the allocation of the Forward Purchase Shares among the Purchasers to be determined by the Adviser, in
its sole discretion (the “Adviser Allocation”). Each Forward Purchase Share will have the same terms as the private
placement shares to be issued under the Private Placement Shares Purchase Agreement substantially in the form attached as Exhibit 10.6
to the Registration Statement, in connection with the IPO.


 



     


     


    

 


(ii) The
Company shall require the Purchasers to purchase the Forward Purchase Shares pursuant to Section 1(a)(i) hereof by delivering notice (the
“Company Notice”) to the Adviser and the Purchasers, at least five (5) Business Days before the funding of the FPS
Purchase Price to an account specified by the Company, specifying the anticipated date of the Business Combination Closing and instructions
for wiring the FPS Purchase Price to an account designated by the Company. At least two (2) Business Days before the anticipated date
of the Business Combination Closing specified in such Company Notice, (i) the Adviser shall deliver notice of the Adviser Allocation (the
“Adviser Allocation Notice”) to the Company and the Purchasers and (ii) each Purchaser shall deliver its respective
portion of the FPS Purchase Price in cash via wire transfer to the account specified in such Company Notice, to be held in escrow pending
the FPS Closing (as defined below). If the FPS Closing does not occur within thirty (30) days after the Purchasers deliver the FPS Purchase
Price to such account, the Company shall, upon request of the Adviser, return to the Purchasers the FPS Purchase Price, provided that
the return of the FPS Purchase Price placed in escrow shall not terminate this Agreement or otherwise relieve either party of any of its
obligations hereunder and the Company may provide a subsequent Company Notice pursuant to this Section 1(a)(ii). 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.


 


(iii) The
closing of the sale of the Forward Purchase Shares (the “FPS Closing”) shall be held on the same date and substantially
concurrently with the Business Combination Closing (such date being referred to as the “FPS Closing Date”). At the
FPS Closing, the Company will issue to each Purchaser the number of Forward Purchase Shares set forth in the Adviser Allocation Notice,
each registered in the name of the respective Purchaser.


 


(b) Delivery
of Forward Purchase Shares.


 


(i) The
Company shall register each Purchaser as the owner of the number of Forward Purchase Shares set forth in the Adviser Allocation Notice
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
FPS Closing Date.


 


(ii) Each
book entry for the Forward Purchase Shares shall contain a notation, and each certificate (if any) evidencing the Forward Purchase Shares
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.”


 


(c) Registration
Rights. The Purchasers shall have registration rights as set forth in the
Registration Rights Agreement substantially in the form attached as Exhibit 10.4 of the Registration Statement (the “Registration
Rights Agreement”).

2. Representations
and Warranties of the Purchasers. Each Purchaser represents and warrants, severally and not jointly, to the Company as follows, as
of the date hereof:


 


(a) Organization
and Power. The Purchaser is duly formed and validly existing and in good standing in its jurisdiction of incorporation or organization
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 against the Purchaser in accordance with its terms,
except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent conveyance and any other laws of general
application affecting enforcement of creditors’ rights generally, (b) as limited by laws relating to the availability of specific
performance, injunctive relief or other equitable remedies, or (c) to the extent the indemnification provisions contained in the Registration
Rights Agreement may be limited by applicable federal or state securities laws.


 


(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, (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 Forward Purchase Shares 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 Forward Purchase Shares. 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 Forward Purchase Shares, as well as the terms of the Company’s proposed IPO, with the
Company’s management.


 


(g) Restricted
Securities. The Purchaser understands that the offer and sale of the Forward Purchase Shares have not been registered under the Securities
Act, by reason of a specific exemption from the registration provisions of the Securities Act that 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 Forward Purchase Shares are “restricted securities” under applicable U.S. federal and state securities
laws and that, pursuant to these laws, the Purchaser must hold the Forward Purchase Shares 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 Forward Purchase Shares for resale, except pursuant to the
Registration Rights Agreement. 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 Forward
Purchase Shares, and on requirements relating to the Company that are outside of the Purchaser’s control, and which the Company
is under no obligation and may not be able to satisfy. The Purchaser understands that the offering to the Purchaser of the Forward Purchase
Shares 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 or Section 12 of the Securities Act with respect to the Forward Purchase Shares.


 


(h) No
Public Market. The Purchaser understands that no public market now exists for the Forward Purchase Shares, and that the Company has
made no assurances that a public market will ever exist for the Forward Purchase Shares.


 


(i) High
Degree of Risk. The Purchaser understands that its agreement to purchase the Forward Purchase Shares involves a high degree of risk,
which could cause the Purchaser to lose all or part of its investment.


 


(j) 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 of the Forward Purchase Shares.


 


(k) Non-Public
Information. The Purchaser acknowledges its obligations under applicable securities laws with respect to the treatment of material
non-public information relating to the Company.


 






    4


     


    

 


(l) Affiliation
of Certain FINRA Members. The Purchaser is neither a person associated nor affiliated with Cowen and Company, LLC or, to its actual
knowledge, any other member of the Financial Industry Regulatory Authority (“FINRA”) that is participating in the IPO.


 


(m) 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 “Purchaser Parties”) has made, makes or shall be deemed to make any
other express or implied representation or warranty with respect to the Purchaser and this offering, and the Purchaser Parties disclaim
any such representation or warranty. Except for the specific representations and warranties expressly made by the Company in Section 3
of this Agreement and in any certificate or agreement delivered pursuant hereto, the Purchaser Parties specifically disclaim that they
are relying upon any other representations or warranties that may have been made by the Company.

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.


 


(o) 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.


 


(p) 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.
