Agreement


 


		1.	Sale and Purchase.



 


		(a)	Forward Purchase Units.



 


		(i)	Subject to Sections 1(a)(ii), (iii) and (iv), the Company shall issue and sell
to the Purchaser, and the Purchaser shall purchase from the Company, up to a maximum of 7,500,000 Forward Purchase Units (the “Maximum
Units”) for a purchase price of $10.00 per Forward Purchase Unit (the “Forward Purchase Price”),
or up to a maximum of $75,000,000 in the aggregate. 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, mutatis mutandis.



 


		(ii)	The number of Forward Purchase Units to be issued and sold by the Company and purchased by the Purchaser
hereunder shall be determined as follows:



 


		(A)	As soon as reasonably practicable, but in no event less than ten (10) Business Days (as defined below)
prior to the Company’s entry into the Definitive Agreement, the Company shall provide the Purchaser with notice (the “Initial
Company Notice”) of the number of Forward Purchase Units that it desires the Purchaser to purchase pursuant to this Agreement,
which shall be equal to its good faith estimate of that number which, after payment of the aggregate Forward Purchase Price by the Purchaser,
will result in gross proceeds to the Company equal to the amount of funds necessary for the Company to satisfy the Cash Requirements less
the Available Cash; provided, however, that such number shall in no event exceed the Maximum Units. Following delivery of
the Initial Company Notice, the Company shall provide the Purchaser with such other information as the Purchaser (or any applicable Transferee
pursuant to Section 4(b) hereof) may reasonably request so that the Purchaser (or such Transferee) may seek the approval of
its board of directors, board of managers, members, investment committee or other governing body to consummate the purchase of the Forward
Purchase Units hereunder.



 


		(B)	Within five (5) Business Days after receipt of the Initial Company Notice, the Purchaser shall provide
the Company with notice (the “Initial Purchaser Notice”) of the decision of its board of directors, board of
managers, members, investment committee or other governing body as to the maximum number of Forward Purchase Units it wishes to purchase
pursuant to this Agreement, if any, which shall not exceed the Maximum Units, which notice shall constitute the binding obligation of
the Purchaser to purchase such number of Forward Purchase Units, subject to the terms and conditions of this Agreement.



 


		(iii)	At least two (2) Business Days before the Business Combination Closing, the Company shall provide the
Purchaser with an updated notice (the “Final Company Notice”) including:



 


		(A)	its determination, based on the actual number of Public Shares validly submitted for redemption or other
changes in the Cash Requirements, of the number of Forward Purchase Units that it requires the Purchaser to purchase pursuant to this
Agreement;



 






    2


     


    

 


		(B)	the anticipated date of the Business Combination Closing; and



 


		(C)	instructions for wiring the Forward Purchase Price.



 


		(iv)	In the event that any Definitive Agreement is terminated or the transaction contemplated thereby is abandoned,
the procedures completed pursuant to clause (ii) and (iii) above to determine the number of Forward Purchase Units to be purchased
by the Purchaser in connection with such Definitive Agreement shall be disregarded and the provisions of clause (ii) and clause (iii)
above must be separately completed for each Definitive Agreement entered into by the Company.



 


		(v)	The closing of the sale of Forward Purchase Units (the “Forward Closing”) shall
be held on the same date and concurrently with 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
the Forward Purchase Price for the Forward Purchase Units by wire transfer of U.S. dollars in immediately available funds to the account
specified by the Company in such notice to be held in escrow until the Forward Closing. Immediately prior to the Forward Closing on the
Forward Closing Date, (i) the Forward Purchase Price shall be released from escrow automatically and without further action by the Company
or the Purchaser, and (ii) 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 within five (5) Business Days of 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.



 


		(b)	Legends. Each register and book entry for the Forward Purchase Securities shall contain a notation,
and each certificate (if any) evidencing the Forward Purchase 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 SECURITIES ACT OF 1933, AS AMENDED, OR THE SECURITIES LAWS OF ANY STATE OR OTHER JURISDICTION, AND

ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN FORWARD PURCHASE AGREEMENT BY AND BETWEEN THE HOLDER AND THE COMPANY. COPIES OF SUCH
AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.”

the Company as follows, as of the date hereof:

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 (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 (as defined below) may be limited by applicable federal or state securities laws.



 






    3


     


    

 


		(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 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 Units, 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
Units to the Purchaser has not been, and will not be, registered under the Securities Act of 1933, as amended (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 or exercised, 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 the Forward Purchase Securities.



 






    4

Securities, and that the Company has made no assurances that a public market will ever exist for the Forward Purchase Securities.

Securities involves a high degree of risk which could cause the Purchaser to lose all or part of its investment.

Regulation D promulgated under the Securities Act.



 


		(k)	No General Solicitation. Neither the Purchaser, nor any of its officers, directors, employees,
agents, shareholders or partners has either directly or indirectly, including, through a broker or finder (i) engaged in any general solicitation,

laws with respect to the treatment of non-public information relating to the Company.

Upon any such assignment:

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.



 


		(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, (ii) 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

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

    11


     


    

 


		(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
Forward Purchase Securities and the securities issuable upon conversion or exercise of the Forward Purchase 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)	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.
