Agreement


 


1. Sale and Purchase.


 


(a) Purchase of Shares.


 


(i) Commencing
on the Mailing Date and through the close of business on the second Business Day (as defined below) after the deadline (the “Redemption
Deadline”) for holders of Class A Shares to elect to redeem their Class A Shares (the “Purchase
Deadline”), the Purchaser shall (provided it is lawful to do so and to the extent requested by the Company) use
reasonable best efforts to purchase Class A Shares, at any one time or from time to time and in such amount or amounts, for an
aggregate purchase price up to (but not exceeding) the Forward Commitment. All such purchases under this Section 1(a)(i)
shall be made by the Purchaser via one or more open market purchases or in one or more privately negotiated transactions with
one or more third parties, including through forward contracts, provided that: (a) any such privately negotiated transactions
settle no later than, and are conditioned upon, the substantially concurrent Business Combination Closing, (b) the Purchaser shall
not be required to purchase any Class A Shares at a per share price in excess of the estimated per share redemption price set
forth in the Proxy Statement and (c) no such purchases shall occur until at least 90 days following the IPO Closing. On the
date immediately following the Purchase Deadline, and at such other times as may be requested by the Company, the Purchaser shall
(x) notify the Company in writing of the number of Class A Shares so purchased pursuant to this Section 1(a)(i) (the “Market
Shares”) and the aggregate purchase price paid therefor by the Purchaser and (y) in the case of any Market Shares
acquired in privately negotiated transactions with one or more third parties, provide the Company with all documentation reasonably
requested by the Company and its advisors (including without limitation, its legal counsel) and its transfer agent and proxy solicitor
to confirm that: (A) the Purchaser purchased, or has contracted to purchase, such Market Shares, and (B) the seller of such Market
Shares has provided to the Purchaser a representation that (I) the seller voted such Market Shares in favor of the Business Combination
and the other proposals of the Company set forth in the Proxy Statement and (II) the seller of such Market Shares did not exercise
its redemption rights with respect to such Market Shares in connection with the special meeting to approve the proposed Business
Combination; provided that such information shall not be publicly disclosed by the Company without the Purchaser’s prior
written consent. To the extent the Company requires less than the Forward Commitment, the Company shall deliver written notice
to the Purchaser before the Purchase Deadline, specifying the number of Class A Shares the Purchaser is required to purchase,
the aggregate purchase price of which shall not exceed the Forward Commitment. 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.


 






    2


     


    

 


(ii) Reserved.


 


(iii) The
Purchaser agrees and acknowledges that up to $75,000,000 of the Forward Commitment may be restructured into an investment in other
equity securities (the “Forward Purchase Securities”) of the Company, in which case (i) the terms of such Forward
Purchase Securities shall be mutually agreed between the Company and the Purchaser and such Forward Purchase Securities shall be
issued by the Company and purchased by the Purchaser, and (ii) the Company shall use reasonable best efforts to structure the terms
and offering of the Forward Purchase Securities to facilitate the resale of the Forward Purchase Securities, including, without
limitation, any resale pursuant to Rule 144 or Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”);
provided that such restructuring shall not occur, such terms shall not be agreed upon, and any related purchase agreement shall
not be entered into, until at least 90 days following the IPO Closing. The aggregate purchase price for the Forward Purchase Securities
is hereinafter referred to as the “FPS Purchase Price.” Notwithstanding
anything to the contrary contained herein, the amount of Forward Purchase Securities to be purchased by the Purchaser will be reduced
by the aggregate amount of Forward Purchase Securities, if any, purchased by third parties in private placements or privately negotiated
transactions to occur substantially concurrently with the Business Combination Closing.


 


(iv) The
Company acknowledges that it shall cause the payment to the Purchaser of a commitment fee (the “Commitment Fee”)
in connection with its agreement to purchase the Market Shares and/or the Forward Purchase Securities; provided, that no Commitment
Fee shall be due if (i) the Company notifies the Purchaser that it does not require the Purchaser to provide the Forward Commitment,
or (ii) the Purchaser exercises its Right of Excusal (as defined below). The Commitment Fee shall be equal to $2,500,000 to be
paid in cash by wire transfer of immediately available funds to an account designated by the Purchaser on the date of the announcement
of the execution of a definitive agreement for a Business Combination.


 


(v) In
the event the Company and the Purchaser mutually agree to sell and purchase Forward Purchase Securities as described in Section
1(a)(iii) hereof, the Company shall deliver notice to the Purchaser, at least one (1) Business Day before the funding of the FPS
Purchase Price to the escrow account (or an alternative account agreed to by the Company and the Purchaser), specifying the number
of Forward Purchase Securities the Purchaser is required to purchase, the anticipated date of the Business Combination Closing,
the aggregate FPS Purchase Price and instructions for wiring the FPS Purchase Price to an account of a third-party escrow agent
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
Agreement”). At least one (1) Business Day before the anticipated date of the Business Combination Closing specified
in such notice, the Purchaser shall deliver the FPS 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 FPS Purchase Price to the Escrow Agent, the Escrow Agreement will provide that the Escrow
Agent automatically return to the Purchaser the FPS Purchase Price, provided that the return of the funds placed in escrow shall
not terminate the Agreement or otherwise relieve either party of any of its obligations hereunder.


 






    3


     


    

 


(vi) The
closing of the sale of the Forward Purchase Securities (the “FPS 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”), provided that the Closing Date shall not occur earlier than 90 days following the IPO Closing. At the
FPS Closing, the Company will issue to the Purchaser the Forward Purchase Securities, each registered in the name of the Purchaser,
against (and concurrently with) payment of the FPS Purchase Price.


 


(vii) The
Company shall keep the Purchaser informed as to the progress of identifying and evaluating potential Business Combination targets
(each a “Target”). The Company shall use reasonable best efforts to
provide Purchaser with such information and access as may reasonably be requested by Purchaser in connection with its rights hereunder,
including (i) participation, upon reasonable advance notice, by senior management in a reasonable number of meetings, presentations
and due diligence sessions at times and in locations reasonably acceptable to the Company, and (ii) furnishing Purchaser, to the
extent reasonably available to the Company, with reasonable documents or other information related to Target. Notwithstanding anything
to the contrary herein, the Purchaser shall be excused from its obligation to purchase the Market Shares and/or the Forward Purchase
Securities in whole or in part in connection with a specific Business Combination (the “Right
of Excusal”) for any reason, including, without limitation, if it has determined that such purchase would constitute
a conflict of interest, if it does not deliver an Acceptance Notice (as defined below) before the Acceptance Deadline (as defined
below) as described below:


 


(A) The
Company shall provide notice to the Purchaser upon reaching an agreement in principle to enter into a Business Combination with
a specific Target. Such written notice shall include sufficient information about such Target that the Purchaser has the ability
to thoroughly evaluate the proposed Business Combination.


 


(B) At
least seven (7) Business Days prior to any vote of the Board of Directors of the Company (the “Board”)
to approve the execution of a definitive agreement for a Business Combination with Target (a “Definitive
Agreement”), written notice (the “Transaction Notice”)
shall be delivered by the Company to the Purchaser (the “Notice Date”)
of the Company’s intention to hold such a Board vote. Such Transaction Notice shall set forth the material terms and such
other information as may be reasonably necessary for the Purchaser to evaluate the terms of such Business Combination.


 


(C) The
Purchaser shall have until ten (10) calendar days after the Notice Date (such date, the “Acceptance
Deadline”) to deliver written notice (an “Acceptance Notice”)
to the Company that it will purchase the Market Shares and/or the Forward Purchase Securities in whole or in part. The Company
shall not call for a Board vote on the proposed Business Combination until after the expiration of the Acceptance Deadline.


 






    4


     


    

 


(D) For
the avoidance of doubt, after the Acceptance Deadline, the Purchaser no longer has the right to purchase any Forward Purchase Securities.


 


(E) The
Purchaser acknowledges and understands that in order to participate in the Company’s interactions with any Targets, and in
order to receive information possessed by the Company related to such Targets, the Purchaser will be required to enter into or
be joined to confidentiality and nondisclosure agreements on customary and reasonable terms with such Targets restricting the use
and disclosure of such information, and that, under certain circumstances, the Purchaser may come into possession of material,
nonpublic information regarding a publicly traded company.


 


(b) Delivery of Forward Purchase
Securities.


 


(i) The
Company shall register the Purchaser as the owner of the Forward Purchase Securities purchased by the Purchaser hereunder 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 FPS Closing.


 


(ii) 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 MAY NOT BE TRANSFERRED IN VIOLATION OF SUCH ACT AND LAWS.


 


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.”


 


(c) Legend
Removal. If the Forward Purchase 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, then at the Purchaser’s
request, the Company will cause the Company’s transfer agent to remove the legend set forth in Section 1(b)(ii). 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 issue such Forward Purchase Securities without any such legend


 






    5


     


    

 


(d) Registration Rights.
The Purchaser shall have registration rights with respect to the Forward Purchase Securities pursuant to a Registration Rights

authority to carry on its business as presently conducted and as proposed to be conducted.

other laws of general application affecting enforcement of creditors’ rights generally and (b) as limited by laws
relating to the availability of specific performance, injunctive relief or other equitable remedies.


 


(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

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

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 they may be converted into, for resale, except for 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 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. The Purchaser understands that the offering of the Forward Purchase

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 Forward Purchase Securities. The Purchaser’s
subscription and purchase and payment for and continued beneficial ownership of the Forward Purchase Securities will not violate
any applicable securities or other laws of the Purchaser’s jurisdiction.

(b) Redemption
and Liquidation. The Purchaser hereby waives, with respect to any Class A Shares held by it, any redemption rights it may have
in connection with (i) the consummation of a Business Combination, including, without limitation, any such rights available in
the context of a stockholder vote to approve such Business Combination and (ii) any stockholder 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 certificate
of incorporation or in the context of a tender offer made by the Company to purchase Class A Shares, it being understood that the

The Purchaser hereby agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection

Combination, 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 vote on behalf of the Purchaser, which power of
attorney shall be deemed to be coupled with an interest.

    15


     


    

 


(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

(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 litigation 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 Delaware, 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 located in the
county of New York and to the jurisdiction of the United States District Court for the Southern District of New York in New York
county 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 located
in the county of New York or the United States District Court for the Southern District of New York in New York county, and (iii)
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.


 






    16


     


    

 


(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 The Depository Trust Company fees associated with the issuance of the Securities and the
securities issuable upon conversion of the Forward Purchase Securities (if any).


 


(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 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.
