RE: Securities Subscription Agreement

 

Ladies and Gentlemen:

 

This agreement (the “Agreement”)
is entered into on May 21, 2021 by and between BurTech LP LLC, a Delaware limited liability company (the “Subscriber”
or “you”), and BurTech Acquisition Corp., a Delaware corporation (the “Company,” “we”
or “us”). Pursuant to the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 8,625,000
shares of Class B common stock, $0.0001 par value per share of the Company (the “Shares”), up to 1,125.000 of
which are subject to forfeiture by you if the underwriters of the initial public offering (“IPO”) of units (“Units”)
of the Company, do not fully exercise their over-allotment option (the “Over-allotment Option”). The Company and the
Subscriber’s agreements regarding such Shares are as follows:

 

1. Purchase of Securities.

 

1.1.  Purchase of Shares. For
the sum of $25,000 (the “Purchase Price”), which the Company acknowledges receiving in cash, the Company hereby issues
the Shares to the Subscriber, and the Subscriber hereby purchases the Shares from the Company, subject to forfeiture, on the terms and
subject to the conditions set forth in this Agreement.  Concurrently with the Subscriber’s
execution of this Agreement, the Company shall, at its option, deliver to the Subscriber a certificate registered in the Subscriber’s
name representing the shares (the “Original Certificate”), or effect such delivery in book-entry form.

 

2. Representations, Warranties and Agreements.

 

2.1.   Subscriber’s Representations,
Warranties and Agreements. To induce the Company to issue the Shares to the Subscriber, the Subscriber hereby represents and warrants
to the Company and agrees with the Company as follows:

 

2.1.1. No Government Recommendation or
Approval. The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of
the offering of the Shares.

 

2.1.2. No Conflicts. The execution,
delivery and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated hereby do not violate,
conflict with or constitute a default under (i) the formation and governing documents of the Subscriber, (ii) any agreement,
indenture or instrument to which the Subscriber is a party or (iii) any law, statute, rule or regulation to which the Subscriber
is subject, or any agreement, order, judgment or decree to which the Subscriber is subject.

 

2.1.3. Organization and Authority.
The Subscriber is a Delaware limited liability company, validly existing and in good standing under the laws of Delaware and possesses
all requisite power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery
by you, this Agreement is a legal, valid and binding agreement of Subscriber, enforceable against Subscriber in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the
enforcement of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought
in a proceeding at law or in equity).

 

    

     

    

 

2.1.4. Experience, Financial Capability
and Suitability. Subscriber is: (i) sophisticated in financial matters and is able to evaluate the risks and benefits of the
investment in the Shares and (ii) able to bear the economic risk of its investment in the Shares for an indefinite period of time
because the Shares have not been registered under the Securities Act (as defined below) and therefore cannot be sold unless subsequently
registered under the Securities Act or an exemption from such registration is available. Subscriber is capable of evaluating the merits
and risks of its investment in the Company and has the capacity to protect its own interests. Subscriber must bear the economic risk of
this investment until the Shares are sold pursuant to: (i) an effective registration statement under the Securities Act or (ii) an
exemption from registration available with respect to such sale. Subscriber is able to bear the economic risks of an investment in the
Shares and to afford a complete loss of Subscriber’s investment in the Shares.

 

2.1.5. Access to Information; Independent
Investigation. Prior to the execution of this Agreement, the Subscriber has had the opportunity to ask questions of and receive answers
from representatives of the Company concerning an investment in the Company, as well as the finances, operations, business and prospects
of the Company, and the opportunity to obtain additional information to verify the accuracy of all information so obtained. In determining
whether to make this investment, Subscriber has relied solely on Subscriber’s own knowledge and understanding of the Company and
its business based upon Subscriber’s own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber
understands that no person has been authorized to give any information or to make any representations which were not furnished pursuant
to this Section 2 and Subscriber has not relied on any other representations or information in making its investment decision, whether
written or oral, relating to the Company, its operations and/or its prospects.

 

2.1.6. Regulation D Offering. Subscriber
represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the
Securities Act of 1933, as amended (the “Securities Act”) and acknowledges the sale contemplated hereby is being made
in reliance on a private placement exemption to “accredited investors” within the meaning of Section 501(a) of Regulation
D under the Securities Act or similar exemptions under state law.

 

2.1.7. Investment Purposes. The Subscriber
is purchasing the Shares solely for investment purposes, for the Subscriber’s own account and not for the account or benefit of
any other person, and not with a view towards the distribution or dissemination thereof. The Subscriber did not decide to enter into this
Agreement as a result of any general solicitation or general advertising within the meaning of Rule 502 under the Securities Act.

 

2.1.8. Restrictions on Transfer; Shell
Company. Subscriber understands the Shares are being offered in a transaction not involving a public offering within the meaning of
the Securities Act. Subscriber understands the Shares will be “restricted securities” within the meaning of Rule 144(a)(3) under
the Securities Act, and Subscriber understands that the certificates or book-entries representing the Shares will contain a legend in
respect of such restrictions. If in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Shares, such
Shares may be offered, resold, pledged or otherwise transferred only pursuant to: (i) registration under the Securities Act, or (ii) an
available exemption from registration. Subscriber agrees that if any transfer of its Shares or any interest therein is proposed to be
made, as a condition precedent to any such transfer, Subscriber may be required to deliver to the Company an opinion of counsel satisfactory
to the Company. Absent registration or an exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that
because the Company is a shell company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year
following consummation of the initial business combination of the Company, despite technical compliance with the requirements of Rule 144
and the release or waiver of any contractual transfer restrictions.

 

2.1.9. No Governmental Consents. No
governmental, administrative or other third party consents or approvals are required, necessary or appropriate on the part of Subscriber
in connection with the transactions contemplated by this Agreement.

 

    2

     

    

 

2.2.  Company’s Representations,
Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents and warrants to the Subscriber
and agrees with the Subscriber as follows:

 

2.2.1. Organization and Corporate Power.
The Company is a Delaware corporation and is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably
be expected to have a material adverse effect on the financial condition, operating results or assets of the Company. The Company possesses
all requisite corporate power and authority necessary to carry out the transactions contemplated by this Agreement.

 

2.2.2. No Conflicts. The execution,
delivery and performance of this Agreement and the consummation by the Company of the transactions contemplated hereby do not violate,
conflict with or constitute a default under (i) the Certificate of Incorporation or By Laws of the Company, (ii) any agreement,
indenture or instrument to which the Company is a party or (iii) any law, statute, rule or regulation to which the Company is
subject, or any agreement, order, judgment or decree to which the Company is subject.

 

2.2.3. Title to Securities. Upon issuance
in accordance with, and payment pursuant to, the terms hereof, the Shares will be duly and validly issued, fully paid and non-assessable.
Upon issuance in accordance with, and payment pursuant to, the terms hereof, the Subscriber will have or receive good title to the Shares,
free and clear of all liens, claims and encumbrances of any kind, other than (a) transfer restrictions hereunder and other agreements
to which the Shares may be subject which have been notified to the Subscriber in writing, (b) transfer restrictions under federal
and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.

 

2.2.4. No Adverse Actions. There are
no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i) seek to restrain,
enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii) question the validity
or legality of any transactions or seeks to recover damages or to obtain other relief in connection with any transactions.

 

3. Forfeiture of Shares.

 

3.1.  Partial or No Exercise of the
Over-allotment Option. In the event the Over-allotment Option granted to the underwriters of the IPO is not exercised in full, the
Subscriber acknowledges and agrees that it (or, if applicable, it and any transferees of Shares) shall forfeit any and all rights to such
number of Shares (up to an aggregate of 937,500 Shares and pro rata based upon the percentage of the Over-allotment Option exercised)
such that immediately following such forfeiture, the Subscriber (and all other initial stockholders prior to the IPO, if any) will own
an aggregate number of Shares, not including Shares issuable upon exercise of any warrants or any common stock of the Company purchased
by Subscriber in the IPO or in the aftermarket equal to 20% of the issued and outstanding Shares immediately following the IPO.

 

3.2.  Termination of Rights as Stockholder.
If any of the Shares are forfeited in accordance with this Section 3, then after such time the Subscriber (or successor in interest),
shall no longer have any rights as a holder of such forfeited Shares, and the Company shall take such action as is appropriate to cancel
such forfeited Shares.

 

3.3.  Share Certificates. In
the event an adjustment to the Original Certificates, if any, is required pursuant to this Section 3, then the Subscriber shall return
such Original Certificates to the Company or its designated agent as soon as practicable upon its receipt of notice from the Company advising
Subscriber of such adjustment, following which a new certificate (the “New Certificate”), if any, shall be issued in
such amount representing the adjusted number of Shares held by the Subscriber. The New Certificate, if any, shall be returned to the Subscriber
as soon as practicable. Any such adjustment for any uncertificated securities held by the Subscriber shall be made in book-entry form.

 

4. Waiver of Liquidation Distributions; Redemption Rights.
In connection with the Shares purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or
claim of any kind in or to any distributions by the Company from the trust account which will be established for the benefit of the Company’s
public stockholders and into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”),
in the event of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For
purposes of clarity, in the event the Subscriber purchases Shares in the IPO or in the aftermarket, any additional Shares so purchased
shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right to
redeem any Shares into funds held in the Trust Account upon the successful completion of an initial business combination.

 

    3

     

    

 

5. Restrictions on Transfer.

 

5.1.  Securities Law Restrictions.
In addition to any restrictions to be contained in that certain letter agreement (commonly known as an “Insider Letter”)
to be dated as of the closing of the IPO by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate
or otherwise dispose of all or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form
under the Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be effective
or (b) the Company has received an opinion from counsel reasonably satisfactory to the Company, that such registration is not required
because such transaction is exempt from registration under the Securities Act and the rules promulgated by the Securities and Exchange
Commission thereunder and with all applicable state securities laws.

 

5.2.   Lock-up.
Subscriber acknowledges that the Securities will be subject to lock-up provisions (the “Lock-up”) contained in the
Insider Letter.

 

5.3.   Restrictive Legends.
Any certificates representing the Shares shall have endorsed thereon legends substantially as follows:

 

“THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED,
SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS
OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE OPINION OF COUNSEL, IS AVAILABLE.”

 

“THE SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO
A LOCKUP AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE TERM OF THE LOCKUP.”

 

5.4.  Additional Shares or Substituted
Securities. In the event of the declaration of a share dividend, the declaration of an extraordinary dividend payable in a form other
than Shares, a spin-off, a share split, an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s
outstanding Shares without receipt of consideration, any new, substituted or additional securities or other property which are by reason
of such transaction distributed with respect to any Shares subject to this Section 5 or into which such Shares thereby become convertible
shall immediately be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities
or property shall be made to the number and/or class of Shares subject to this Section 5 and Section 3.

 

5.5.  Registration Rights. Subscriber
acknowledges that the Shares are being purchased pursuant to an exemption from the registration requirements of the Securities Act and
will become freely tradable only after certain conditions are met or they are registered pursuant to a registration rights agreement to
be entered into with the Company prior to the closing of the IPO.

 

6. Other Agreements.

 

6.1.  Further Assurances. Subscriber
agrees to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this
Agreement.

 

6.2.  Notices. All notices, statements
or other documents which are required or contemplated by this Agreement shall be: (i) in writing and delivered personally or sent
by first class registered or certified mail, overnight courier service or facsimile or electronic transmission to the address designated
in writing, (ii) by facsimile to the number most recently provided to such party or such other address or fax number as may be designated
in writing by such party and (iii) by electronic mail, to the electronic mail address most recently provided to such party or such
other electronic mail address as may be designated in writing by such party. Any notice or other communication so transmitted shall be
deemed to have been given on the day of delivery, if delivered personally, on the business day following receipt of written confirmation,

6.3.  Entire Agreement. This
Agreement, together with the Insider Letter and the Registration Rights Agreement, each substantially in the form to be filed as an exhibit
to the Registration Statement on Form S-1 associated with the Company’s IPO, embodies the entire agreement and understanding
between the Subscriber and the Company with respect to the subject matter hereof and supersedes all prior oral or written agreements and
understandings relating to the subject matter hereof. No statement, representation, warranty, covenant or agreement of any kind not expressly
set forth in this Agreement shall affect, or be used to interpret, change or restrict, the express terms and provisions of this Agreement.

 

6.4.   Modifications and Amendments.
The terms and provisions of this Agreement may be modified or amended only by written agreement executed by all parties hereto.

 

6.5.  Waivers and Consents. The
terms and provisions of this Agreement may be waived, or consent for the departure therefrom granted, only by a written document executed
by the party entitled to the benefits of such terms or provisions. No such waiver or consent shall be deemed to be or shall constitute
a waiver or consent with respect to any other terms or provisions of this Agreement, whether or not similar. Each such waiver or consent
shall be effective only in the specific instance and for the purpose for which it was given, and shall not constitute a continuing waiver
or consent.

 

6.6.  Assignment. The rights
and obligations under this Agreement may not be assigned by either party hereto without the prior written consent of the other party.

 

6.7.  Benefit. All statements,
representations, warranties, covenants and agreements in this Agreement shall be binding on the parties hereto and shall inure to the
benefit of the respective successors and permitted assigns of each party hereto. Nothing in this Agreement shall be construed to create
any rights or obligations except among the parties hereto, and no person or entity shall be regarded as a third-party beneficiary of this
Agreement.

 

6.8.  Governing Law. This Agreement
shall be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders
of such state, without giving effect to the conflict of law principles thereof.

 

6.9.  Severability. In the event
that any court of competent jurisdiction shall determine that any provision, or any portion thereof, contained in this Agreement shall
be unreasonable or unenforceable in any respect, then such provision shall be deemed limited to the extent that such court deems it reasonable
and enforceable, and as so limited shall remain in full force and effect. In the event that such court shall deem any such provision,
or portion thereof, wholly unenforceable, the remaining provisions of this Agreement shall nevertheless remain in full force and effect.

 

6.10.  No Waiver of Rights, Powers
and Remedies. No failure or delay by a party hereto in exercising any right, power or remedy under this Agreement, and no course of
dealing between the parties hereto, shall operate as a waiver of any such right, power or remedy of such party. No single or partial exercise
of any right, power or remedy under this Agreement by a party hereto, nor any abandonment or discontinuance of steps to enforce any such
right, power or remedy, shall preclude such party from any other or further exercise thereof or the exercise of any other right, power
or remedy hereunder. The election of any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other
available remedies. No notice to or demand on a party not expressly required under this Agreement shall entitle the party receiving such
notice or demand to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the
party giving such notice or demand to any other or further action in any circumstances without such notice or demand.

 

6.11.  Survival of Representations
and Warranties. All representations and warranties made by the parties hereto in this Agreement or in any other agreement, certificate
or instrument provided for or contemplated hereby, shall survive the execution and delivery hereof and any investigations made by or on

    5

     

    

 

6.12.  No Broker or Finder. Each
of the parties hereto represents and warrants to the other that no broker, finder or other financial consultant has acted on its behalf
in connection with this Agreement or the transactions contemplated hereby in such a way as to create any liability on the other. Each
of the parties hereto agrees to indemnify and save the other harmless from any claim or demand for commission or other compensation by
any broker, finder, financial consultant or similar agent claiming to have been employed by or on behalf of such party and to bear the
cost of legal expenses incurred in defending against any such claim.

 

6.13.  Headings and Captions.
The headings and captions of the various subdivisions of this Agreement are for convenience of reference only and shall in no way modify
or affect the meaning or construction of any of the terms or provisions hereof.

 

6.14.  Counterparts. This Agreement
may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall
become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties
need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic
delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed)
with the same force and effect as if such signature page were an original thereof.

 

6.15.  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. 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.

 

6.16.  Mutual Drafting. This
Agreement is the joint product of the Subscriber and the Company and each provision hereof has been subject to the mutual consultation,
negotiation and agreement of such parties and shall not be construed for or against any party hereto.

 

7.  Voting and Tender of Shares. Subscriber agrees
to vote the Shares in favor of an initial business combination that the Company negotiates and submits for approval to the Company’s
stockholders and shall not seek redemption with respect to such Shares. Additionally, the Subscriber agrees not to tender any Shares in
connection with a tender offer presented to the Company’s stockholders in connection with an initial business combination negotiated
by the Company.

 

8.        Indemnification.
Each party shall indemnify the other against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred
as a result of such party’s breach of any representation, warranty, covenant or agreement in this Agreement.

2. Representations and Warranties of the
Subscriber

 

The Subscriber represents and warrants to the Company
that:

 

2.1. No Government Recommendation
or Approval.  The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement
of the Company or the Placement of the Securities.

 

2.2. Accredited Investor.
The Subscriber represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under
the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is
being made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities
Act and similar exemptions under state law.

 

2.3.  Intent.  The
Subscriber is purchasing the Securities solely for investment purposes, for the Subscriber’s own account (and/or for the account
or benefit of its members or affiliates, as permitted, pursuant to the terms of an agreement (the “Insider Letter”)
to be entered into with respect to the Securities between, among others, the Subscriber  and the Company, as described in the
Registration Statement), and not with a view to the distribution thereof and the Subscriber has no present arrangement to sell the Securities
to or through any person or entity except as may be permitted under the Insider Letter.  The Subscriber shall not engage in
hedging transactions with regard to the Securities unless in compliance with the Securities Act.

   

2.4.  Restrictions on
Transfer.  The Subscriber acknowledges and understands the Units are being offered in a transaction not involving a public offering
in the United States within the meaning of the Securities Act.  The Securities have not been registered under the Securities
Act and, if in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be
offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities
Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant
to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable
securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, the Subscriber acknowledges and understands the
Securities are subject to transfer restrictions as described in Section 8 hereof. The Subscriber agrees that if any transfer of its Securities
or any interest therein is proposed to be made, as a condition precedent to any such transfer, the Subscriber may be required to deliver
to the Company an opinion of counsel satisfactory to the Company with respect to such transfer. Absent registration or another available
exemption from registration, the Subscriber agrees it will not resell the Securities (unless otherwise permitted pursuant to the Insider
Letter, as described in the Registration Statement).  The Subscriber further acknowledges that because the Company is a shell
company, Rule 144 may not be available to the Subscriber for the resale of the Securities until the one year anniversary following consummation
of the initial Business Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or
waiver of any contractual transfer restrictions.

 

    

     

    

 

2.5.   Sophisticated
Investor.

 

(i)  The Subscriber
is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Securities.

 

(ii) The Subscriber is aware
that an investment in the Securities is highly speculative and subject to substantial risks because, among other things, the Securities
are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently
registered under the Securities Act or an exemption from such registration is available. The Subscriber is able to bear the economic risk
of its investment in the Securities for an indefinite period of time.

 

2.6.  Independent
Investigation.  The Subscriber, in making the decision to purchase the Units, has relied upon an independent investigation of
the Company and has not relied upon any information or representations made by any third parties or upon any oral or written representations
or assurances from the Company, its officers, directors or employees or any other representatives or agents of the Company, other than
as set forth in this Agreement. The Subscriber is familiar with the business, operations and financial condition of the Company and has
had an opportunity to ask questions of, and receive answers from the Company’s officers and directors concerning the Company and
the terms and conditions of the offering of the Units and has had full access to such other information concerning the Company as the
Subscriber has requested. The Subscriber confirms that all documents that it has requested have been made available and that the Subscriber
has been supplied with all of the additional information concerning this investment which the Subscriber has requested.

 

2.7    Organization
and Authority.  The Subscriber is duly organized, validly existing and in good standing under the laws of the State of Delaware
and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

 

2.8.   Authority.
This Agreement has been validly authorized, executed and delivered by the Subscriber and is a valid and binding agreement enforceable
in accordance with its terms, subject to the general principles of equity and to bankruptcy or other laws affecting the enforcement of
creditors’ rights generally.

  

2.9.     No
Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated
hereby do not violate, conflict with or constitute a default under (i) the Subscriber's charter documents, (ii) any agreement
or instrument to which the Subscriber is a party or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or
any agreement, order, judgment or decree to which the Subscriber is subject.

 

2.10.  No Legal Advice
from Company.  The Subscriber acknowledges it has had the opportunity to review this Agreement and the transactions contemplated
by this Agreement and the other agreements entered into between the parties hereto with the Subscriber’s own legal counsel and investment
and tax advisors.  Except for any statements or representations of the Company made in this Agreement and the other agreements
entered into between the parties hereto, the Subscriber is relying solely on such counsel and advisors and not on any statements or representations
of the Company or any of its representatives or agents for legal, tax or investment advice with respect to this investment, the transactions
contemplated by this Agreement or the securities laws of any jurisdiction.

 

2.11.  Reliance on Representations
and Warranties.  The Subscriber understands the Units are being offered and sold to the Subscriber in reliance on exemptions
from the registration requirements under the Securities Act, and analogous provisions in the laws and regulations of various states, and
that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings
of the Subscriber set forth in this Agreement in order to determine the applicability of such provisions.

 

2.12.  No General Solicitation.  The
Subscriber is not subscribing for the Units as a result of or subsequent to any general solicitation or general advertising, including
but not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or
broadcast over television or radio, or presented at any seminar or meeting or in a registration statement with respect to the IPO filed
with the Securities and Exchange Commission (“SEC”).

 

    

     

    

 

2.13.  Legend.  The
Subscriber acknowledges and agrees the certificates (if any) evidencing each of the Securities shall bear a restrictive legend (the “Legend”),
in form and substance substantially as set forth in Section 4 hereof.

5.  Waiver of
Liquidation Distributions.

 

In connection with the Securities
purchased pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any
distributions of the amounts in the Trust Account with respect to the Securities, whether (i) in connection with the exercise of redemption
rights if the Company consummates the Business Combination, (ii) in connection with any tender offer conducted by the Company prior to
a Business Combination, (iii) upon the Company’s redemption of shares of Common Stock sold in the Company’s IPO upon the Company’s

of the Company’s public shares if the Company does not timely complete the Business Combination or (B) with respect to any other
provision relating to stockholders’ rights or pre-Business Combination activity.  In the event the Subscriber purchases
shares of Common Stock in the IPO or in the aftermarket, any additional shares so purchased shall be eligible to receive the redemption
value of such shares of Common Stock upon the same terms offered to all other purchasers of Common Stock in the IPO in the event the Company
fails to consummate the Business Combination.

  

6.  Terms of
Placement Warrants. Each Placement Warrant shall have the terms set forth in the Warrant Agreement.

 

    

     

    

 

7. Rescission Right Waiver
and Indemnification.

 

7.1. The Subscriber understands
and acknowledges an exemption from the registration requirements of the Securities Act requires there be no general solicitation of purchasers
of the Units. In this regard, if the IPO were deemed to be a general solicitation with respect to the Units, the offer and sale of such
Units may not be exempt from registration and, if not, the Subscriber may have a right to rescind its purchase of the Units. In order
to facilitate the completion of the Placement and in order to protect the Company, its stockholders and the amounts in the Trust Account
from claims that may adversely affect the Company or the interests of its stockholders, the Subscriber hereby agrees to waive, to the
maximum extent permitted by applicable law, any claims, right to sue or rights in law or arbitration, as the case may be, to seek rescission
of its purchase of the Units. The Subscriber acknowledges and agrees this waiver is being made in order to induce the Company to sell
the Units to the Subscriber. The Subscriber agrees the foregoing waiver of rescission rights shall apply to any and all known or unknown
actions, causes of action, suits, claims or proceedings (collectively, “Claims”) and related losses, costs, penalties,
fees, liabilities and damages, whether compensatory, consequential or exemplary, and expenses in connection therewith, including reasonable
attorneys’ and expert witness fees and disbursements and all other expenses reasonably incurred in investigating, preparing or defending
against any Claims, whether pending or threatened, in connection with any present or future actual or asserted right to rescind the purchase
of the Units hereunder or relating to the purchase of the Units and the transactions contemplated hereby.

 

7.2. The Subscriber agrees
not to seek recourse against the Trust Account for any reason whatsoever in connection with its purchase of the Units or any Claim that
may arise now or in the future.

 

7.3. The Subscriber acknowledges
and agrees that the stockholders of the Company are and shall be third-party beneficiaries of this Section 7.

 

7.4. The Subscriber agrees
that to the extent any waiver of rights under this Section 7 is ineffective as a matter of law, the Subscriber has offered such waiver
for the benefit of the Company as an equitable right that shall survive any statutory disqualification or bar that applies to a legal
right. The Subscriber acknowledges the receipt and sufficiency of consideration received from the Company hereunder in this regard.

  

8. Terms of the Units
and Placement Warrants 

 

8.1. The Units and their component
parts are substantially identical to the units to be offered in the IPO except that: (i) the Units and component parts are subject to
the transfer restrictions described in the Insider Letter, (ii) the Placement Warrants will be non-redeemable if called for redemption
pursuant to Section 6.1 of the Warrant Agreement so long as they are held by the Subscriber (or any of its permitted transferees) and
as otherwise provided in Section 5 herein, and may be exercisable on a “cashless” basis if held by the Subscriber or
its permitted transferees, as further described in the Warrant Agreement and (iii) the Units and component parts are being purchased pursuant
to an exemption from the registration requirements of the Securities Act and will become freely tradable only after the expiration of
the lockup described above in clause (i) and they are registered pursuant to the Registration Rights Agreement to be signed on or before
the date of the Prospectus or an exemption from registration is available.

 

8.2 The Subscriber agrees
to vote the Placement Shares in accordance with the terms of the Insider Letter and as otherwise described in the Registration Statement.

Law; Jurisdiction; Waiver of Jury Trial

waive any right to a jury trial in connection with any litigation pursuant to this Agreement and the transactions contemplated hereby.

Amendment

 

10.1.  Assignment. Neither
this Agreement nor any rights hereunder may be assigned by any party to any other person other than by the Subscriber to a person agreeing
to be bound by the terms hereof, including the waiver contained in Section 7 hereof.

 

10.2.  Entire Agreement.
This Agreement sets forth the entire agreement and understanding between the parties as to the subject matter thereof and merges and supersedes

11.1   Notices.
Unless otherwise provided herein, any notice or other communication to a party hereunder shall be sufficiently given if in writing and
personally delivered or sent by facsimile or other electronic transmission with copy sent in another manner herein provided or sent by
courier (which for all purposes of this Agreement shall include Federal Express or other recognized overnight courier) or mailed to said
party by certified mail, return receipt requested, at its address provided for herein or such other address as either may designate for
itself in such notice to the other.  Communications shall be deemed to have been received when delivered personally, on the
scheduled arrival date when sent by next day or 2nd-day courier service, or if sent by facsimile upon receipt of confirmation of transmittal
or, if sent by mail, then three days after deposit in the mail. If given by electronic transmission, such notice shall be deemed to be

notice; (b) if by a posting on an electronic network together with separate notice to the stockholder of such specific posting, upon
the later of (1) such posting and (2) the giving of such separate notice; and (c) if by any other form of electronic transmission,
when directed to the stockholder.

 

12. Counterparts

 

This Agreement may be executed
in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective
when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign
the same counterpart. In the event that any signature is delivered by facsimile transmission or by e-mail delivery of a “pdf”
format data file, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature
is executed) with the same force and effect as if such facsimile or “.pdf” signature page were an original thereof.

 

13. Survival; Severability

 

13.1.  Survival. The
representations, warranties, covenants and agreements of the parties hereto shall survive the Closing Dates.

 

13.2. Severability. In the

void, this Agreement shall continue in full force and effect without said provision; provided that no such severability shall be effective
if it materially changes the economic benefit of this Agreement to any party.
