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, on the IPO Closing, the Purchaser hereby irrevocably subscribes for and agrees to
purchase from the Company, and the Company hereby agrees to issue and sell to the Purchaser, the number of Private Placement Warrants
set forth on Schedule A hereto for the aggregate purchase price set forth on Schedule A hereto (the “Initial
Warrant Purchase Price”).

 

(ii)    Subject
to the terms and conditions hereof, on the IPO Closing, the Purchaser shall purchase from the Company, and the Company shall issue
and sell to the Purchaser, the number of Founder Shares set forth on Schedule A hereto for the aggregate purchase
price set forth on Schedule A hereto (the “Initial Founder Share Purchase Price” and together with
the Initial Warrant Purchase Price, the “Initial Purchase Price”), by wire transfer of immediately available
funds or other means approved by the Company. If the IPO Closing has not occurred by April 30, 2021, this Agreement shall terminate
and be of no further force or effect.

 

(iii)
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.

 

(iv) 
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 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 the Purchaser shall not be
obligated to remit the Initial Purchase Price as set forth in this Section 1(a)(iv) and any of the Purchaser, the Company or the
Sponsor may in its sole discretion terminate this Agreement which shall 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 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. If the IPO Closing has not occurred by April 30, 2021, this
Agreement shall terminate and be of no further force or effect.

(v)
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 Founder Shares and Private Placement Warrants as indicated on Schedule
A. 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 Founder Shares and 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 Founder Shares and 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.

 

(vi)
On the date of the IPO Closing, the Company shall issue to the Purchaser the number of Founder Shares and 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 and Founder Shares as set forth on Schedule A.

 

 

(b)
Closing Conditions. The Purchaser’s obligation to purchase the Subscribed Securities and the Company’s obligation

true and correct on the date of this Agreement and shall be true and correct on the IPO Closing or the Over-allotment Closing,
as applicable, as if made on the date of such closing; and

 

(iii)
In the case of the Company and the Sponsor, each Subscribing Party other than the Purchaser shall have on the IPO Closing or the
Over-allotment Closing, as applicable, concurrently consummated its subscription under its Subscription Agreement.

 

(iv)
The Sponsor and any of its affiliates shall have purchased at least eighty percent (80%) of the Private Placement Warrants offered
by the Company in connection with the IPO which are not purchased by the Subscribing Parties.

 

(c) 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 upon the purchase thereof (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 the purchase 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.

 

    3

     

    

 

THE
SECURITIES MAY NOT BE SOLD, PLEDGED, OFFERED, HYPOTHECATED OR OTHERWISE TRANSFERRED, EXCEPT PURSUANT TO THE TERMS AND CONDITIONS
OF A CERTAIN SUBSCRIPTION AGREEMENT BY AND AMONG THE HOLDER AND THE OTHER PARTIES THERETO, COPIES OF WHICH AGREEMENT MAY BE
OBTAINED UPON WRITTEN REQUEST TO THE SECRETARY OF THE COMPANY.”

 

(d)
 Legend Removal. Following the expiration of the transfer restrictions set forth in Section 6(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, 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 commercially
reasonable efforts to cause the Company’s transfer agent to remove the legend set forth in Section 1(c)(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.

 

(e) Registration
Rights. On the Effective Date, the Company shall enter into that certain 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.

 

2.

forfeit, transfer to a third person, exchange, subject to transfer, vesting or conditional forfeiture provisions or amend the
terms of all or any portion of the Founder Shares and/or the Private Placement Warrants (or the Sponsor’s membership interests
representing an interest in any of the foregoing) or (ii) to enter into any other arrangements with respect to the Founder Shares
and/or the Private Placement Warrants (or the Sponsor’s membership interests representing an interest in any of the foregoing),
to facilitate the consummation of such Business Combination (each, a “Change in Investment”), such Change in
Investment shall apply pro rata to the Purchaser and the Sponsor based on the relative number of Founder Shares and/or Private
Placement Warrants held by each on the date hereof or, if applicable, the date of the Over-allotment Closing; provided,
however, that in no event shall such Change in Investment apply to more than 75% of the Founder Shares held by the Purchaser
and/or 75% of the Private Placement Warrants held by the Purchaser on the date hereof or, if applicable the date of the Over-allotment
Closing. The Purchaser agrees to take all steps and execute all such agreements as may be necessary or reasonably requested by
the Sponsor to effectuate such Change in Investment on the same terms as applicable to the Sponsor.

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

    4

     

    

 

(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

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,

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

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

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.

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 Securities.

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

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

of the Business Combination; (x) in the event of the Company’s liquidation prior to the completion of the Business Combination;
(xi) to the Purchaser’s affiliates, to any investment fund or other entity controlled or managed by the Purchaser, or to

shareholders having the right to exchange their Class A Common Stock for cash, securities or other property subsequent to the
Company’s completion of the Business Combination (each of the foregoing, a “Permitted Transferee”); provided,
however, that in the case of clauses (i) through (viii) or with the Company’s prior written consent, these Permitted
Transferees must enter into a written agreement agreeing to be bound by the terms and transfer restrictions of this Agreement.
As used in this Agreement, “Transfer” shall mean the (x) sale of, offer to sell, contract or agreement

that this Section 6(a) shall not prohibit the Purchaser from effecting a Short Sale (as defined below) with securities
that do not constitute “Securities” under this Agreement.

(b) Trust
Account.

 

(i) The
Purchaser hereby acknowledges that it is aware that the Company will establish the Trust Account for the benefit of its public
stockholders upon the IPO Closing. The Purchaser hereby agrees that it has no right, title, interest or claim of any kind in or
to any monies held in the Trust Account, or any other asset of the Company as a result of any liquidation of the Company, except
for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public Shares held by it.

 

(ii) The
Purchaser hereby agrees that it shall have no right of set-off or any right, title, interest or claim of any kind (“Claim”)
to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account
that it may have now or in the future, except for redemption and liquidation rights, if any, the Purchaser may have in respect
of any Public Shares held by it. In the event the Purchaser has any Claim against the Company under this Agreement, the Purchaser
shall pursue such Claim solely against the Company and its assets outside the Trust Account and not against the property or any
monies in the Trust Account, except for redemption and liquidation rights, if any, the Purchaser may have in respect of any Public
Shares held by it.

 

(c)
No Short Sales. The Purchaser hereby agrees that neither it, nor any person or entity acting on its behalf, will engage

6(c), “Short Sales” shall include, without limitation, all “short sales” as defined in Rule 200 promulgated
under Regulation SHO under the Exchange Act, and all types of direct and indirect stock pledges (other than pledges in the ordinary
course of business as part of prime brokerage arrangements), forward sale contracts, options, puts, calls, swaps and similar arrangements
(including on a total return basis). Notwithstanding anything to the contrary contained herein, the Purchaser shall not be prohibited
from effecting a short sale with securities that do not constitute “Securities” under this Agreement.

 

(d)
Use of Purchaser’s Name. Neither the Company nor the Sponsor will, without the written consent of the Purchaser in
each instance, use in advertising, publicity or otherwise the name of the Purchaser or any of its affiliates, or any director,
officer or employee of the Purchaser, nor any trade name, trademark, trade device, service mark, symbol or any abbreviation, contraction
or simulation thereof owned by the Purchaser or its affiliates or any information relating to the business or operations of the
Purchaser or its affiliates (including, for the avoidance of doubt, any investment vehicles, funds or accounts managed thereby).
Notwithstanding the foregoing, the Company may disclose the Purchaser’s name and information concerning the Purchaser
(A) to the extent required by law, regulation or regulatory request, including in the Registration Statement or (B) to
the Company’s lawyers, independent accountants and to other advisors and service providers who reasonably require the Purchaser’s
information in connection with the provision of services to the Company, are advised of the confidential nature of such information
and are obligated to keep such information confidential. The Company and the Sponsor agree to provide to the Purchaser for the
Purchaser’s review any disclosure in any registration statement, proxy statement or other document in advance of the submission,
filing or disclosure of such document in connection with the transactions contemplated by this Agreement with respect to the Purchaser
or any of its affiliates, and will not make any such submission, filing or disclosure without including any revisions reasonably
requested in writing by the Purchaser or to the extent the Purchaser has a good faith objection to such submission, filing or
disclosure.

(f)
Material Non-Public Information. Notwithstanding anything to the contrary herein, the Company shall not, without the prior
written consent of a General Counsel or Chief Compliance Officer (or their designee) of the Purchaser, disclose to the Purchaser
any information (including, without limitation, information that may be provided to the Company) that is material non-public information
with respect to any public company, including the Company.

 

(g)
Independent Nature of Rights and Obligations. Nothing contained herein, and no action taken by any party pursuant hereto,
shall be deemed to constitute the Purchaser and the Sponsor as, and the Sponsor acknowledges that the Purchaser and the Sponsor
do not so constitute, a partnership, an association, a joint venture or any other kind of entity, or create a presumption that
the Purchaser and the Sponsor are in any way acting in concert or as a group with respect to such obligations or the transactions
contemplated by this Agreement or any matters, and the Sponsor acknowledges that the Purchaser and the Sponsor are not acting
in concert or as a group, and the Sponsor shall not assert any such claim, with respect to such obligations or the transactions
contemplated by this Agreement.

 

(h)
Prohibition on Certain Business Combinations. The Sponsor shall not cause the Company to enter into a business combination
where the resultant company would be classified as a U.S. Real Property Holding Corporation under Section 897 of the Internal
Revenue Code of 1986, as amended.

(o) Construction. 
The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of
intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption
or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement.
Any reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and
regulations promulgated thereunder, unless the context requires otherwise. The words “include,” “includes,”
and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine,
and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include
the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,”
“hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a
whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty,
and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty,
or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating
to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not
detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

 

(p) Waiver. 
No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional
or not, may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder
or affect in any way any rights arising because of any prior or subsequent occurrence.

 

(q) Specific
Performance.  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, in equity, in contract, in tort or otherwise. .

 

(r)
No Third-Party Beneficiaries. This Agreement is for the sole benefit of the parties hereto (and their respective successors
and permitted assigns) and nothing herein, express or implied, is intended to or shall confer upon any other person any legal
or equitable right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

 

(s) 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 6(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.

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 Private Placement Warrants set forth on Schedule A hereto for the aggregate
purchase price set forth on Schedule A hereto (the “Initial Warrant Purchase Price”).

 

(ii) On the IPO Closing, the Purchaser
shall purchase from the Company, and the Company shall issue and sell to the Purchaser, the number of Founder Shares set forth
on Schedule A hereto for the aggregate purchase price set forth on Schedule A hereto (the “Initial
Founder Share Purchase Price” and together with the Initial Warrant Purchase Price, the “Initial Purchase Price”),
by wire transfer of immediately available funds or other means approved by the Company. If the IPO Closing has not occurred by
April 30, 2021, this Agreement shall terminate and be of no further force or effect.

 

(iii) 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.

 

(iv)
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 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 the Purchaser shall not be obligated to remit the Initial Purchase Price as set forth in this
Section 1(a)(iv) and any of the Purchaser, the Company or the Sponsor may in its sole discretion terminate this Agreement
which shall 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 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. If the IPO Closing has not occurred by April 30, 2021, this Agreement
shall terminate and be of no further force or effect.

 

(v) 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 Founder Shares and Private Placement Warrants as indicated on Schedule A. 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 Founder Shares and 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 Founder Shares and
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

     

    

 

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

 

(b) Closing Conditions. The Purchaser’s
obligation to purchase the Subscribed Securities and the Company’s obligation to sell the Subscribed Securities to the Purchaser
is conditioned upon satisfaction of the following conditions precedent (any or all of which may be waived by the Company, the Sponsor
and the Purchaser in its sole discretion with respect to the other parties’ conditions):

 

(i) On the IPO Closing or the Over-allotment
Closing, as applicable, no legal, administrative or regulatory action, suit or proceeding shall be pending which seeks to restrain
or prohibit the transactions contemplated by this Agreement;

 

(ii) The representations and warranties
of the Company, the Sponsor and the Purchaser, contained in this Agreement shall have been true and correct on the date of this
Agreement and shall be true and correct on the IPO Closing or the Over-allotment Closing, as applicable, as if made on the date
of such closing; and

 

(iii) In the case of the Company
and the Sponsor, each Subscribing Party other than the Purchaser shall have on the IPO Closing or the Over-allotment Closing, as
applicable, concurrently consummated its subscription under its Subscription Agreement.

 

(c) 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 upon the purchase thereof
(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 the purchase 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.”

 

    3

     

    

 

(d) Legend Removal. Following the expiration
of the transfer restrictions set forth in Section 6(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, 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 commercially reasonable efforts to cause the Company’s transfer
agent to remove the legend set forth in Section 1(c)(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.

 

(e) 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.

 

2. Potential Forfeiture. The Purchaser
agrees that if, in connection with a Business Combination, the Sponsor decides (i) to forfeit, transfer to a third person, exchange,
subject to transfer, vesting or conditional forfeiture provisions or amend the terms of all or any portion of the Founder Shares
and/or the Private Placement Warrants (or the Sponsor’s membership interests representing an interest in any of the foregoing)
or (ii) to enter into any other arrangements with respect to the Founder Shares and/or the Private Placement Warrants (or the Sponsor’s
membership interests representing an interest in any of the foregoing), including voting in favor of any amendment to the terms
of the Founder Shares and/or the Private Placement Warrants (each, a “Change in Investment”), such Change in
Investment shall apply pro rata to the Purchaser and the Sponsor based on the relative number of Founder Shares and/or Private
Placement Warrants to be held by each on the Business Combination Closing; provided, however that in no event shall such Change
in Investment apply to more than 75% of the Founder Shares to be purchased by the Purchaser and/or 75% of the Private Placement
Warrants held by the Purchaser. The Purchaser agrees to take all steps and execute all such agreements as may be necessary or reasonably
requested by the Sponsor to effectuate such Change in Investment on the same terms as applicable to the Sponsor.

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

 

(b) Authorization. The Purchaser has
full power and authority to enter into this Agreement. This Agreement, when executed and delivered by the Purchaser, will constitute
the valid and legally binding obligation of the Purchaser, enforceable against the Purchaser in accordance with its terms, except
(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.

 

(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

    4

     

    

 

(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.

(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.

 

(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) to its knowledge, engaged in any general solicitation, 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.

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) waive,
and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it
is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment
or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding
is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

 

(k) WAIVER OF JURY TRIAL. THE PARTIES
HERETO HEREBY WAIVE ANY RIGHT TO A JURY TRIAL IN CONNECTION WITH ANY LITIGATION PURSUANT TO THIS AGREEMENT AND THE TRANSACTIONS
CONTEMPLATED HEREBY.

 

(l) Amendments. This Agreement may
not be amended, modified or waived as to any particular provision, except with the prior written consent of the Company and the
Purchaser.

 

(m) Severability. The provisions of
this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the validity or
enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any party hereto
or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance with
its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have
the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific
words or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.

 

(n) Expenses. Each of the Company,
the Sponsor 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, except that the Sponsor will be responsible for the Purchaser’s legal
fees in an amount up to $50,000. The Company shall be responsible for the fees of its transfer agent, stamp taxes and all of The

(o) Construction. The parties hereto
have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation
arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will
arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any reference to any
federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations promulgated
thereunder, unless the context requires otherwise. The words “include,” “includes,” and “including”
will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be
construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless
the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,”
“hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless
expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent
significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact
that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative
levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto
is in breach of the first representation, warranty, or covenant.

 

(p) Waiver. No waiver by any party
hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not, may be deemed
to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in any way
any rights arising because of any prior or subsequent occurrence.

 

(q) Specific Performance. 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) No Third-Party Beneficiaries. This
Agreement is for the sole benefit of the parties hereto (and their respective successors and permitted assigns) and nothing herein,
express or implied, is intended to or shall confer upon any other person any legal or equitable right, benefit or remedy of any
nature whatsoever under or by reason of this Agreement.

 

(s) 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 6(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.
