 AGREEMENT 

1. Sale and Purchase. 

(a) Forward Purchase Securities. 

(i) The Company shall issue and sell to Purchaser, and the Purchaser shall purchase from the Company that number of Forward
Purchase Shares, up to a maximum of 15,000,000 Forward Purchase Shares (the “Maximum Shares”) plus that number of Forward Purchase Warrants up to a maximum of 7,500,000 Forward Purchase Warrants (the “Maximum
Warrants”) in each case as determined as set forth in clause 1(a)(ii), for $10.00 per Forward Purchase Unit, or an aggregate maximum amount of $150,000,000. 

(ii) The number of Forward Purchase Units to be issued and sold by the Company and purchased by the Purchaser hereunder shall
equal that number which, after payment of the aggregate Forward Purchase Price by the Purchaser, will result in gross proceeds to the Company in an aggregate amount equal to the amount of funds necessary for the Company to consummate the Business
Combination and pay related fees and expenses, less amounts available to the Company from the Trust Account (after giving effect to any redemptions of Public Shares), any other equity financing source obtained by the Company for such purpose at or
prior to the consummation of the Business Combination, and amounts the Purchaser or its affiliates have expended to repurchase Public Warrants in any tender offer, plus any additional amounts mutually agreed by the Company and the Purchaser that may
be retained by the post-Business Combination company for working capital or other purposes, but in no event shall the number of Forward Purchase Shares or Forward Purchase Warrants purchased hereunder exceed the Maximum Shares or the Maximum
Warrants, respectively. 
 (iii) 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 share of Class A Common Stock 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 following 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 Transferees (as defined below). If the Forward Purchase Warrants are held by Persons (as defined below) other than the Purchaser or its Transferees, the Forward Purchase Warrants will have the same terms
as the Public Warrants, as set forth in the Warrant Agreement.

 (iv) The Company shall require the Purchaser to purchase the Forward Purchase
Securities by delivering notice to the Purchaser, following the close of business two (2) Business Days before the Business Combination Closing, specifying the number of Forward Purchase Shares and Forward Purchase Warrants the Purchaser is
required to purchase, the date of the Business Combination Closing, the aggregate Forward Purchase Price and instructions for wiring the Forward Purchase Price. The closing of the sale of Forward Purchase Securities (the “Forward
Closing”) shall be on the same date and immediately prior to the Business Combination Closing (such date being referred to as the “Forward Closing Date”). 

(v) At least one (1) Business Day prior to the date of the Business Combination Closing, the Purchaser shall deliver to
the Company, to be held in escrow until the Forward Closing, the aggregate 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, (A) the aggregate 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 Securities 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 aggregate 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 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 COMPANY. COPIES OF SUCH AGREEMENT MAY BE OBTAINED UPON WRITTEN REQUEST TO
THE CHIEF FINANCIAL OFFICER OF THE COMPANY.”

(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. 

(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

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

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 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 shares of Class A Common Stock for which they may be
exercised, for resale, except as provided herein (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 has filed the Registration Statement for its proposed IPO. The Purchaser understands that the offering of Forward Purchase Securities and transactions
contemplated hereunder are not and are 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. 

(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, and that it will be contractually obligated to vote or
cause the Sponsor to vote the Sponsor Founder Shares in favor of the Business Combination as provided herein. 
 (j) Accredited
Investor. The Purchaser is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the Securities Act. 
 (k)
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) engaged in any general
solicitation, or (ii) published any advertisement in connection with the offer and sale of the Forward Purchase Securities. 
 (l)
Residence. The Purchaser’s principal place of business is the office or offices located at the address of the Purchaser set forth on the signature page hereof.

 (m) Adequacy of Financing. The Purchaser has available to it sufficient funds to satisfy
its obligations under this Agreement. 
 (o) Affiliation of Certain FINRA Members. The Purchaser is neither a person associated nor
affiliated with Oppenheimer & Co. or EarlyBirdCapital, Inc. or, to its actual knowledge, any other member of the Financial Industry Regulatory Authority (“FINRA”) that is participating in the IPO.

Securities and the Class A Common Stock underlying the Forward Purchase Warrants (collectively, the “Registrable Securities”), and the Company shall use its commercially reasonable efforts to have the Forward Registration
Statement declared effective as soon as practicable after the filing thereof; provided, however, that the Company’s obligations to include the Registrable Securities in the Forward Registration Statement are contingent upon the Purchaser

the meaning of Section 15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), and the officers, directors, partners, members, managers, stockholders, agents,
affiliates, employees and investment advisers of each such controlling person, to the fullest extent permitted by applicable law, from and against any and all losses, claims, damages, liabilities, costs (including, without limitation, reasonable
costs of preparation and investigation and reasonable attorneys’ fees) and expenses (collectively, “Losses”), as incurred, that arise out of or are based upon (A) any untrue or alleged untrue statement of 

  
 8 








 a material fact contained in the Forward Registration Statement, any prospectus included in the
Forward Registration Statement or any form of prospectus or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein (in the case of any prospectus or form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading, or (B) any violation or alleged violation
by the Company of the Securities Act, the Exchange Act or any state securities law or any rule or regulation thereunder, in connection with the performance of its obligations under this Section 4, except to the extent, but
only to the extent that such untrue statements, alleged untrue statements, omissions or alleged omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. Such
indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of an indemnified party and shall survive the transfer of the Registrable Securities by the Company. The Company shall notify the Purchaser promptly
of the institution, threat or assertion of any proceeding arising from or in connection with the transactions contemplated by this Section 4 of which the Company is aware. 

(ii) The Purchaser shall indemnify and hold harmless the Company, its directors, officers, agents and employees, each person
who controls the Company (within the meaning of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the directors, officers, agents or employees of such controlling persons, to the fullest extent permitted by
applicable law, from and against all Losses, as incurred, arising out of or that are based upon any untrue or alleged untrue statement of a material fact contained in the Forward Registration Statement, any prospectus included in the Forward
Registration Statement, or any form of prospectus, or in any amendment or supplement thereto or in any preliminary prospectus, or arising out of or relating to any omission or alleged omission of a material fact required to be stated therein or
necessary to make the statements therein (in the case of any prospectus, or any form of prospectus or supplement thereto, in light of the circumstances under which they were made) not misleading to the extent, but only to the extent that such untrue
statements or omissions are based solely upon information regarding the Purchaser furnished in writing to the Company by the Purchaser expressly for use therein. In no event shall the liability of the Purchaser be greater in amount than the dollar
amount of the net proceeds received by the Purchaser upon the sale of the Registrable Securities giving rise to such indemnification obligation. 

(c) Transfer. This Agreement and all of the Purchaser’s rights and obligations hereunder (including Purchaser’s obligation to
purchase the Forward Purchase Securities, 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”) with the written consent of the
Company. Upon any such assignment: 
 (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 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 

  
 9 








 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 

(ii) 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 Schedule A to this Agreement to reflect each transfer and updating the “Number of Forward Purchase Shares”, “Number of Forward Purchase Warrants”, and
“Aggregate Purchase Price for Forward Purchase Securities” on the Purchaser’s signature page hereto to reflect such reduced number of Forward Purchase Securities. For the avoidance of doubt, this Agreement need not be amended and
restated in its entirety, but only Schedule A and 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.

 (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

 13 








 (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, constitute 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. 
 (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 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 New York, without giving effect to its choice of
laws principles. 
 (j) Jurisdiction. The parties (i) submit to the jurisdiction of the state courts of New York and 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 Court for the Southern District of New York, 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. 

  
 14 








 (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 The Depository Trust Company fees associated with the issuance of the Forward Purchase Securities and the securities issuable upon exercise of the Forward Purchase Warrants. 

(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. 

  
 15 








 (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.
