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 Securities.


 


(i) The
Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, 2,500,000 Forward Purchase Units
for a purchase price of $10.00 per Forward Purchase Unit, or $25,000,000 in the aggregate (the “Forward Purchase Price”).


 


(ii) Each
Forward Purchase Warrant will have the same terms as each Private Placement Warrant, 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 30 days after the Business Combination Closing and 12 months from the IPO Closing, and will expire five years
after the Business Combination Closing or earlier upon the liquidation of the Company, as described in the Warrant Agreement.
The Forward Purchase Warrants will be non-redeemable and exercisable on a cashless basis so long as they are held by the Purchaser
or its Permitted Transferees (as defined below). For so long as the Forward Purchase Warrants are held by the Purchaser or its
Permitted Transferees, the Forward Purchase Warrants will not be exercisable more than five years from the effective date of the
Registration Statement in accordance with FINRA Rule 5110(f)(2)(G)(i). If the Forward Purchase Warrants are held by Persons (as
defined below) other than the Purchaser or its Permitted Transferees, the Forward Purchase Warrants will have the same terms as
the Public Warrants, as set forth in the Warrant Agreement.


 


(iii) The
Company shall require the Purchaser to purchase the Forward Purchase Units by delivering notice to the Purchaser, at least five
(5) Business Days before the Business Combination Closing, specifying the date of the Business Combination Closing and instructions
for wiring the Forward Purchase Price. The closing of the sale of Forward Purchase Units (the “Forward Closing”)
shall be held on the same date and immediately prior to the Business Combination Closing (such date being referred to as the “Forward
Closing Date”). At least one (1) Business Day prior to the Forward Closing Date, the Purchaser shall deliver to the
Company, to be held in escrow until the Forward Closing, the Forward Purchase Price for the Forward Purchase Securities by wire
transfer of U.S. dollars in immediately available funds to the account specified by the Company in such notice. Immediately prior
to the Forward Closing on the Forward Closing Date, (A) the Forward Purchase Price shall be released from escrow automatically
and without further action by the Company or the Purchaser, and (B) upon such release, the Company shall issue the Forward Purchase
Units to the Purchaser in book-entry form, free and clear of any liens or other restrictions whatsoever (other than those arising
under state or federal securities laws), registered in the name of the Purchaser (or its nominee in accordance with its delivery
instructions), or to a custodian designated by the Purchaser, as applicable. In the event the Business Combination Closing does
not occur on the date scheduled for closing, the Forward Closing shall not occur and the Company shall promptly (but not later
than one (1) Business Day thereafter) return the Forward Purchase Price to the Purchaser. For 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.

formation 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 (as defined below) 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

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,

    3


     


    

 


(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
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 in violation of any state or federal securities
laws, 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 Securities. 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 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 offer and sale of the Forward Purchase Securities to the Purchaser has not
been, and will not be, 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 Forward Purchase Securities 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 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 Forward Purchase Securities, or any Class A Shares into which the
Forward Purchase Securities may be converted into or exercised for, for resale, except for 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 Forward Purchase 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 filed the Registration Statement for its proposed IPO. The
Purchaser understands that the offering of the Forward Purchase 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 Forward
Purchase Securities.


 


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


 


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


 


(j) Accredited
Investor. The Purchaser is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities
Act.

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

of Financing. At the time of the Forward Closing, the Purchaser will have available to it sufficient funds to satisfy its
obligations under this Agreement.

and Warranties of the Company. The Company represents and warrants to the Purchaser as follows:


 


(a) Incorporation
and Corporate Power. The Company is corporation duly incorporated and validly existing and in good standing as a corporation
under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as presently

(b) Transfer.
This Agreement and all of the Purchaser’s rights and obligations hereunder (including the Purchaser’s obligation to

(i) 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 Units 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,

a Transferee’s execution and delivery of a Joinder Agreement, the number of Forward Purchase Units to be purchased by the

by its terms as of a specified date, which shall be true and correct as of such specified date), except where the failure to be
so true and correct would not have a material adverse effect on the Purchaser or its ability to consummate the transactions contemplated
by this Agreement;


 


(iii) The
Purchaser shall have performed, satisfied and complied in all material respects with the covenants, agreements and conditions
required by this Agreement to be performed, satisfied or complied with by the Purchaser at or prior to the Forward Closing; and


 


(iv) No
order, writ, judgment, injunction, decree, determination, or award shall have been entered by or with any governmental, regulatory,
or administrative authority or any court, tribunal, or judicial, or arbitral body, and no other legal restraint or prohibition
shall be in effect, preventing the purchase by the Purchaser of the Forward Purchase Securities.


 


8. Termination.
This Agreement may be terminated at any time prior to the Forward Closing:


 


(a) by
mutual written consent of the Company and the Purchaser;


 


(b) automatically


 


(i) if
the IPO is not consummated on or prior to twelve months from the date of this Agreement; or


 


(ii) if
the Business Combination is not consummated within 24 months from the closing of the IPO, or such later date as may be approved
by the Company’s shareholders.


 


In
the event of any termination of this Agreement pursuant to this Section 8, the FPS 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 stockholders 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.

(c) Survival
of Representations and Warranties. All of the representations and warranties contained herein shall survive the Forward Closing.


 


(d) Entire
Agreement. This Agreement, together with any documents, instruments and writings that are delivered pursuant hereto or referenced
herein, constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes
all prior understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate
in any way to the subject matter hereof or the transactions contemplated hereby.


 


(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 party.


 






    11


     


    

 


(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 the State of New York, without giving effect to its choice of laws principles.


 


(j) Jurisdiction.
The parties (i) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of New York and to the jurisdiction
of the United States District Court for the Southern District of New York for the purpose of any suit, action or other proceeding
arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out of or
based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of
New York, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action
or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is
exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the
venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in
or by such court.


 


(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 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.


 


(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 Forward Purchase Securities.


 






    12


     


    

 


(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) Specific
Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of this Agreement was not performed
by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific performance of the terms
hereof, in addition to any other remedy at law or equity.
