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) 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, and (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. 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.

 

(ii) Reserved.

 

    2

     

    

 

(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”). 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.

 

(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.

 

    3

     

    

 

(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.

 

(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.

 

    4

     

    

 

(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

 

(d) Registration
Rights. The Purchaser shall have registration rights with respect to the Forward Purchase Securities pursuant to a Registration
Rights Agreement to be entered into with the Company prior to the closing of the IPO (the “Registration Rights Agreement”).

 

2. Representations
and Warranties of the Purchaser. The Purchaser represents and warrants to the Company as follows, as of the date hereof:

 

(a) Organization
and Power. The Purchaser is duly organized, validly existing, and in good standing under the laws of the jurisdiction
of its formation (if the concept of “good standing” is a recognized concept in such jurisdiction) and has all requisite
power and authority to carry on its business as presently conducted and as proposed to be conducted.

 

    5

     

    

 

(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 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 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 bound, or (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

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, 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

(g) Restricted
Securities . The Purchaser understands that the Forward Purchase Securities have 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 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 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.

 

(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 its Forward Purchase Securities and Market Shares in favor of the Company’s Business Combination.

 

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

 

(k) Foreign
Investors. If the Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), the Purchaser hereby
represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation
to subscribe for the Forward Purchase Securities or any use of this Agreement, including (i) the legal requirements within its
jurisdiction for the purchase of the Forward Purchase Securities, (ii) any foreign exchange restrictions applicable to such purchase,
(iii) 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.

 

(l) 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 Securities.

page hereof.

 

(n) Adequacy
of Financing. The Purchaser has available to it sufficient funds to satisfy its obligations under this Agreement.

 

(o) 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

hereto, the Purchaser Parties specifically disclaim that they are relying upon any other representations or warranties that may

(i) The
Purchaser hereby acknowledges that it is aware that the Company will establish a trust account (the “Trust

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 Purchaser shall be entitled to redemption and liquidation rights with respect to any public shares held by it in the event

The Purchaser hereby agrees that if the Company seeks stockholder approval of a proposed Business Combination, then in connection
with such proposed Business Combination, the Purchaser shall vote any Class A Shares owned by it in favor of any proposed Business
Combination. If the Purchaser fails to vote any Class A Shares it is required to vote hereunder in favor of a Proposed Business
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

or interpretation of this Agreement.

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)

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.

 

    15

     

    

 

(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 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.

 

    16

     

    

 

(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.

    1

     

    

 

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) Securities.

 

(i) Subject
to the terms and conditions hereof, the Purchaser hereby irrevocably subscribes for and agrees to purchase from the Company, and
the Company agrees to issue and sell to the Purchaser, the number of Subscribed Securities set forth on Schedule A hereto
for the aggregate purchase price set forth on Schedule A hereto (the “Initial Purchase Price”).
The Purchaser acknowledges that the Subscribed Securities, and any securities of the Company that may be distributed to the Purchaser
on account of the Subscribed Securities (collectively, the “Securities”), will be subject to restrictions on
transfer as set forth in this Agreement.

 

(ii) On
the date hereof, (A) the Company shall issue to the Purchaser the number of Founder Shares set forth on Schedule A hereto,
in consideration for the Purchaser’s payment of the portion of the Initial Purchase Price applicable to such Founder Shares,
as set forth on Schedule A hereto, by wire transfer of immediately available funds or other means approved by the Company,
and (B) the Sponsor shall forfeit to the Company for cancellation, for no consideration, and have no further right, title
or interest in, an equal number of Founder Shares. If the IPO Closing has not occurred by March 31, 2019, then the Company will
promptly redeem the Purchaser’s Founder Shares issued pursuant to this Section 1(a)(ii) for a cash payment equal to the Initial
Purchase Price paid by the Purchaser in respect of such Founder Shares, and this Agreement shall terminate and be of no further
force or effect.

 

(iii) The
Company shall notify the Purchaser in writing of the anticipated date of the effectiveness of the Registration Statement (the “Effective
Date”) at least three (3) Business Days (as defined below) prior to the Effective Date, and the Purchaser shall
remit the balance of the Initial Purchase Price to the Company’s transfer agent (to be held in escrow pending the IPO Closing),
by wire transfer of immediately available funds or other means approved by the Company, on the date that is one (1) Business Day
prior to the Effective Date, or such other date as the Company and the Purchaser may agree upon in writing; provided, however,
that if the actual number of Public Units offered and sold in the IPO is less than 20,000,000, then (x) the Purchaser shall not
be obligated to remit the balance of the Initial Purchase Price as set forth in this Section 1(a)(iii) and (y) the Company shall
promptly redeem the Purchaser’s Founder Shares issued pursuant to Section 1(a)(ii) for a cash payment equal to the Initial
Purchase Price paid by the Purchaser in respect of such Founder Shares and this Agreement shall terminate and be of no further
force or effect. As used herein, “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. If the IPO Closing has not occurred by the date that is seven (7) Business Days after the date
on which the Purchaser remitted the balance of its Initial Purchase Price to the Company’s transfer agent, then, unless the
Purchaser otherwise agrees in writing, the Company will promptly cause its transfer agent to return such amounts to the Purchaser.
In the event that the underwriters’ over-allotment option in connection with the IPO (the “Over-allotment Option”)
is exercised, the Purchaser agrees to purchase additional Private Placement Warrants as indicated on Schedule A at a price
of $1.00 per warrant. The Company shall notify the Purchaser in writing of the anticipated date of each closing of the exercise
of the Over-allotment Option, if any (each, an “Over-allotment Closing”) at least three (3) Business Days prior
to such Over-allotment Closing, and the Purchaser shall pay the purchase price for the Private Placement Warrants to be purchased
in connection with such Over-allotment Closing by wire transfer of immediately available funds or other means approved by the Company
on that date that is one (1) Business Day prior to such Over-allotment Closing (to be held in escrow pending such Over-allotment
Closing), or such other date as the Company and the Purchaser may agree upon in writing. If the Over-allotment Closing has not
occurred by the date that is seven (7) Business Days after the date on which the Purchaser remitted the purchase price for
the Private Placement Warrants to be purchased in connection with such Over-allotment Closing, then, unless the Purchaser otherwise
agrees in writing, the Company will promptly cause its transfer agent to return such amounts to the Purchaser.

 

    2

     

    

 

(iv) On
the date of the IPO Closing, the Company shall issue to the Purchaser the number of Private Placement Warrants set forth on Schedule
A hereto. On the date of each Over-allotment Closing, if any, the Company shall issue to Purchaser the number of Private
Placement Warrants as set forth on Schedule A.

 

(b) Delivery
of Securities.

 

(i) The
Company shall register the Purchaser as the owner of the Subscribed Securities with the Company’s transfer agent by book
entry on or prior to the date of the IPO Closing (provided that prior to the Company’s appointment of a transfer agent it
shall register the Purchaser as the owner of such securities in the Company’s stock ledger upon issuance thereof).

 

(ii) Each
register and book entry for the Securities shall contain a notation, and each certificate (if any) evidencing the 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 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.

 

THE SALE, PLEDGE, HYPOTHECATION, OR TRANSFER OF THE SECURITIES
REPRESENTED HEREBY ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN SUBSCRIPTION 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. Following the expiration of the transfer restrictions set forth in Section 5(a), if the 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 of 1933, as amended (the “Securities Act”), or if they
are registered for resale under the Securities Act pursuant to a shelf registration statement, then at the Purchaser’s written
request, the Company will use best efforts to cause the Company’s transfer agent to remove the legend set forth in Section 1(b)(ii),
subject to compliance by the Purchaser with the reasonable and customary procedures for such removal required by the Company or
its transfer agent. 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 Securities without any
such legend.

 

(d) Registration
Rights. On the Effective Date, the Company shall enter into a Registration Rights Agreement (the “Registration Rights
Agreement”) with the Sponsor, the Subscribing Parties and certain other parties thereto, in substantially the form provided
to the Purchaser prior to the date hereof. The Registration Rights Agreement shall provide the Purchaser with registration rights
with respect to the Subscribed Securities that are no less favorable to the Purchaser than the registration rights of the Sponsor
set forth therein.

 

    3

     

    

 

2. Potential
Forfeiture.

 

(a) If
on either (i) on the date of the vote by the Company’s stockholders to approve the Business Combination or (ii) the Business
Day immediately prior to the closing of the Business Combination (each, a “Determination Date”), the Purchaser
beneficially owns or holds, directly or indirectly, including through any firm commitments to purchase, after giving effect to
any redemptions of Common Stock in connection with the Business Combination, a number of Public Shares (the “Determination
Date Shares”) that is less than the Forfeiture Threshold (as defined below), then the Purchaser shall automatically transfer
to the Sponsor or surrender to the Company and have the Company issue an equivalent number of new shares to the Sponsor for no
consideration, and have no further right, title or interest in, a pro rata number of its Founder Shares, provided
that the Purchaser shall not be obligated to transfer to the Sponsor or surrender to the Company any Founder Shares to the extent
that the remaining number of Founder Shares held by the Purchaser would be less than [_](or [_], if the Over-allotment Option is
exercised in full), the pro rata number being calculated as a fraction, the numerator of which is the number of Shortfall Shares
(as defined below) and the denominator is the Forfeiture Threshold. For the avoidance of doubt, in calculating the number of Public
Shares (if any) which the Purchaser beneficially owns or holds, directly or indirectly, for purposes of determining the number
of Determination Date Shares, no Public Shares that are beneficially owned by any other Subscribing Party shall be counted (e.g.,
no Public Shares shall be double counted among Subscribing Parties). The Purchaser shall take all actions as may be reasonably
necessary to consummate any transfer and/or sale contemplated by this Section 2, including entering into agreements
and delivering certificates and instruments and consents as may be deemed by the Company to be necessary or appropriate (which
shall not require the Purchaser to make any representations other than as to its clear title to the applicable Founder Shares and
its power and authorization to effect the transactions contemplated by the applicable agreement or other instrument), and the Purchaser
hereby grants to the Company and any representative designated by the Company without further action by the Purchaser a limited
irrevocable power of attorney to effect any transfer contemplated hereby on behalf of the Purchaser, which power of attorney shall
be deemed to be coupled with an interest.

 

(b) As
used herein, (i) the “Forfeiture Threshold” shall initially mean [_]shares of Class A Common Stock; provided,
that if the actual number of Public Units offered and sold in the IPO is less than 25,000,000, then the Forfeiture Threshold shall
be automatically reduced on a pro rata basis, and (ii) the “Shortfall Shares” shall mean the amount
by which the Forfeiture Threshold exceeds the Determination Date Shares.

 

(c) Solely
by way of example to illustrate the provisions of Section 2(a), if the Forfeiture Threshold is [_]and on a Determination
Date the Purchaser beneficially owns [_]shares of Public Shares (such that the number of Determination Date Shares is [_]), then
the number of Shortfall Shares shall be [_], and the percentage of the Purchaser’s Founder Shares that the Purchaser would
transfer to the Sponsor or surrender to the Company and have the Company issue an equivalent number of new shares to the Sponsor
would be 40% (e.g., [_]divided by [_]).

 

(d) If,
in connection with the expiration or termination of the Over-allotment Option, the Sponsor forfeits any Founder Shares to the Company
for cancellation, then the Purchaser agrees to forfeit its Founder Shares to the Company for cancellation on that same basis (such
that if no portion of the Over-allotment Option is exercised, the Purchaser would forfeit a total of [_]of its Founder Shares,
and if the Over-allotment Option is exercised in part, the Purchaser would forfeit a pro rata portion thereof, based on
the portion of the Over-allotment Option that is not exercised as a percentage of the total number of Public Units issuable upon
exercise of the Over-allotment Option), and hereby grants 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 forfeiture on behalf of the Purchaser, which
power of attorney shall be deemed to be coupled with an interest.

of its formation and has all requisite power and authority to carry on its business as presently conducted and as proposed to be

The Purchaser has full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser,

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 or (ii) as limited by laws
relating to the availability of specific performance, injunctive relief or other equitable remedies.

 

    4

     

    

 

(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, except for filings pursuant to applicable securities
laws, rules or regulations.

 

(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) under
any provisions of its organizational documents, (ii) under 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) under
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’s 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 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 (other than the Company) to sell, transfer or grant participations to such
Person or to any third Person, with respect to any of the 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.

and the terms and conditions of the offering of the 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 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 Securities are “restricted securities” under
applicable U.S. federal and state securities laws and that, pursuant to these laws, the Purchaser must hold the 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 Securities
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 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 confidentially submitted the Registration Statement for its proposed IPO. The Purchaser understands that the offering of 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 with respect to its purchase of Securities hereunder.

 

(h) No
Public Market.  The Purchaser understands that no public market now exists for the Securities, and that the Company has
not made any assurances that a public market will ever exist for the Securities.

 

(i) High
Degree of Risk.  The Purchaser understands that the purchase of the Subscribed 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.

 

    5

General Solicitation.  Neither the Purchaser, nor any of its officers, directors, employees, agents, stockholders or partners

or (ii) published any advertisement in connection with the offer and sale of the Securities.

 

(l) Place
of Investment Decision.  The Purchaser’s investment decision was made in the office or offices located at the address
of the Purchaser set forth on the signature page hereof.

 

(m) Adequacy
of Financing. The Purchaser will, when such funds are due hereunder, have sufficient funds to satisfy its obligations
under this Agreement.

 

(o) No
Other Representations and Warranties; Non-Reliance.  Except for the specific representations and warranties contained
in this Section 3 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

Restrictions.  The Purchaser agrees that it shall not Transfer (as defined below) (i) any Founder Shares until the earlier

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.  Each party hereto agrees that irreparable damage may occur in the event any provision of this Agreement
was not performed by the other party hereto in accordance with the terms hereof and that the such party shall be entitled to specific
performance of the terms hereof, in addition to any other remedy at law or equity.

 

(r) Confidentiality. 
Except as may be required by law, regulation or applicable stock exchange listing requirements (but subject in any case to the
provisions of Section 5(d) hereof), 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.  Notwithstanding the foregoing, the Purchaser shall be permitted
to disclose any information to its affiliates and its and their respective directors, officers, employees, advisors, director or
indirect owners, agents and representatives, in each case so long as such person or entity has been advised of the confidentiality
obligations hereunder; provided that the Purchaser shall be liable for any breach of such confidentiality obligations by any such
person or entity.
