purpose trust company (“Trustee”).

 

WHEREAS, the Company’s
registration statement on Form S-1, File No. 333-254303 (“Registration Statement”) for the initial public offering
of the Company’s units (the “Units”), each of which consists of one share of the Company’s Class
A common stock, par value $0.0001 per share (the “Common Stock”), and one-third of one redeemable warrant, each
whole warrant entitling the holder thereof to purchase one share of Common Stock (such initial public offering hereinafter referred
to as the “IPO”), has been declared effective as of the date hereof (“Effective Date”) by
the Securities and Exchange Commission (capitalized terms used herein and not otherwise defined shall have the meanings set forth
in the Registration Statement);

 

WHEREAS, the Company
has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Morgan Stanley & Co. LLC, as the
representative (the “Representative”) of the several underwriters (the “Underwriters”) in
the IPO;

 

WHEREAS, as described
in the Registration Statement, and in accordance with the Company’s Amended and Restated Certificate of Incorporation, as
the same may be amended from time to time (the “Certificate of Incorporation”), $150,000,000 ($172,500,000 if
the over-allotment option is exercised in full) of the proceeds from the IPO and a simultaneous private placement of warrants will
be delivered to the Trustee to be deposited and held in a segregated trust account located at all times in the United States (the
“Trust Account”) for the benefit of the Company and the holders of the shares of Common Stock included in the
Units issued in the IPO as hereinafter provided (the proceeds to be delivered to the Trustee (and any interest subsequently earned
thereon) will be referred to herein as the “Property”; the stockholders for whose benefit the Trustee shall
hold the Property will be referred to as the “Public Stockholders,” and the Public Stockholders and the Company
will be referred to together as the “Beneficiaries”);

 

WHEREAS, pursuant to
the Underwriting Agreement, a portion of the Property equal to, in the aggregate, 3.5% of the gross proceeds of the IPO, including
any proceeds from the full or partial exercise of the Underwriters’ over-allotment option, is attributable to deferred underwriting
discounts and commissions that will be payable by the Company to the Underwriters upon and concurrently with the consummation of
a Business Combination (as defined below) (the “Deferred Discount”); and

 

WHEREAS, the Company
and the Trustee desire to enter into this Agreement to set forth the terms and conditions pursuant to which the Trustee shall hold
the Property.

 

NOW THEREFORE, IT IS
AGREED:

 

1. Agreements
and Covenants of Trustee. The Trustee hereby agrees and covenants to:

 

(a) Hold
the Property in trust for the Beneficiaries in accordance with the terms of this Agreement in the Trust Account established by
the Trustee initially at J.P. Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of

Investment Company Act that holds itself out as a money market fund selected by the Company meeting the conditions of paragraph
(d) of Rule 2a-7 promulgated under the Investment Company Act (or any successor rule), which invest only in direct U.S. government
treasury obligations; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting
the Company’s instructions hereunder and the Trustee may earn bank credits or other consideration during such periods;

 

     

     

    

 

(d) Collect
and receive, when due, all principal, interest or other income arising from the Property, which shall become part of the “Property,”
as such term is used herein;

of the Trust Account;

 

(i) Commence
liquidation of the Trust Account only after and promptly after receipt of, and only in accordance with, the terms of a letter (“Termination
Letter”), in a form substantially similar to that attached hereto as either Exhibit A or Exhibit B, as
applicable, signed on behalf of the Company by an authorized officer and, in the case of a Termination Letter in a form substantially
similar to that attached hereto as Exhibit A, jointly acknowledged and agreed to by the Representative, and complete the
liquidation of the Trust Account and distribute the Property in the Trust Account, including interest not previously released to
the Company to pay its taxes (net of taxes payable), only as directed in the Termination Letter and the other documents referred
to therein; provided, however, that in the event that a Termination Letter has not been received by the Trustee within the period
of time (the “Last Date”) provided in the Company’s Certificate of Incorporation, the Trust Account shall
be liquidated in accordance with the procedures set forth in the Termination Letter attached as Exhibit B hereto and the
Property in the Trust Account, including interest not previously released to the Company to pay its taxes (net of taxes payable),
shall be distributed to the Public Stockholders of record as of the Last Date; and

 

(j) Upon
receipt of a letter (a “Stockholder Conversion Letter”) in the form of Exhibit C, signed on behalf of
the Company by an authorized officer, distribute to Public Stockholders who properly exercised their conversion rights in connection
with (A) an amendment to the Company’s Certificate of Incorporation (i) to modify the substance or timing of the Company’s

limited distributions referred to in Section 2(a) above shall be made only from income collected on the Property. Except
as provided in Section 2(a) above, no other distributions from the Trust Account shall be permitted except in accordance
with Sections 1(i) or 1(j) hereof.

 

3. Agreements
and Covenants of the Company. The Company agrees and covenants to:

 

(a) Give
all instructions to the Trustee hereunder in writing, signed by any one of the Company’s authorized officers. In addition,
except with respect to its duties under Sections 1(i), 1(j), and 2(a) above, the Trustee shall be entitled
to rely on, and shall be protected in relying on, any verbal or telephonic advice or instruction which it, in good faith and with

Company shall promptly confirm such instructions in writing;

by the Trustee of notice of demand or claim or the commencement of any action, suit, or proceeding, pursuant to which the Trustee
intends to seek indemnification under this paragraph, it shall notify the Company in writing of such claim (hereinafter referred
to as the “Indemnified Claim”). The Trustee shall have the right to conduct and manage the defense against such
Indemnified Claim, provided, that the Trustee shall obtain the consent of the Company with respect to the selection of counsel,
which consent shall not be unreasonably withheld. The Trustee may not agree to settle any Indemnified Claim without the prior written
consent of the Company, which consent shall not be unreasonably withheld. The Company may participate in such action with its own
counsel;

 

(c) Pay
the Trustee an initial acceptance fee, an annual fee, and a transaction processing fee for each disbursement made pursuant to Section
2(a) as set forth on Schedule A hereto, which fees shall be subject to modification by the parties from time to time.
It is expressly understood that the Property shall not be used to pay such fees and further agreed that any fees owed to the Trustee
shall be deducted by the Trustee from the disbursements made to the Company pursuant to Section 1(i) solely in connection
with the Company’s consummation of a merger, capital stock exchange, asset acquisition, stock purchase, recapitalization,
reorganization or other similar business combination with one or more businesses or entities (a “Business Combination”).
The Company shall pay the Trustee the initial acceptance fee and the first annual fee at the consummation of the IPO and thereafter
on the anniversary of the Effective Date. The Company shall not be responsible for any other fees or charges of the Trustee except
as set forth in this Section 3(c), Schedule A and as may be provided in Section 3(b) hereof;

 

(d) In
connection with any vote of the Company’s stockholders regarding a Business Combination, provide to the Trustee an affidavit
or certificate of the inspector of elections for the stockholder meeting verifying the vote of such stockholders regarding such
Business Combination;

 

(e) In
the event that the Company directs the Trustee to commence liquidation of the Trust Account pursuant to Section 1(i), the
Company agrees that it will not direct the Trustee to make any payments that are not specifically authorized by this Agreement;

any action with respect to the Property, other than as directed in Sections 1 and 2 hereof, and the Trustee shall
have no liability to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful
misconduct;

 

    3

     

    

 

(b) Institute
any proceeding for the collection of any principal and income arising from, or institute, appear in, or defend any proceeding of
any kind with respect to, any of the Property unless and until the Trustee shall have received instructions from the Company given

thereto;

 

(c) Change
the investment of any Property, other than in compliance with Section 1(c);

 

(d) Refund
any depreciation in principal of any Property;

 

(e) Assume
that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided
otherwise in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee;

 

(f) The
other parties hereto or to anyone else for any action taken or omitted by the Trustee, or any action suffered by the Trustee to
be taken or omitted, in good faith and in the exercise of the Trustee’s best judgment, except for the Trustee’s gross
negligence, fraud or willful misconduct. The Trustee may rely conclusively and shall be protected in acting upon any order, notice,
demand, certificate, opinion, or advice of counsel (including counsel chosen by the Trustee), statement, instrument, report, or
other paper or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to
the truth and acceptability of any information therein contained) which is believed by the Trustee, in good faith and with reasonable
care, to be genuine and to be signed or presented by the proper person or persons. The Trustee shall not be bound by any notice
or demand, or any waiver, modification, termination, or rescission of this Agreement or any of the terms hereof, unless evidenced
by a written instrument delivered to the Trustee signed by the proper party or parties and, if the duties or rights of the Trustee
are affected, unless it shall give its prior written consent thereto;

 

(g) Verify

payee statements to the Company documenting the taxes, if any, payable by the Company or the Trust Account, relating to the income
earned on the Property;

 

(i) Pay
any taxes on behalf of the Trust Account (it being expressly understood that the Property shall not be used to pay any such taxes
and that such taxes, if any, shall be paid by the Company from funds not held in the Trust Account or released to it under Section
2(a) hereof);

 

(j) Imply
obligations, perform duties, inquire, or otherwise be subject to the provisions of any agreement or document other than this agreement
and that which is expressly set forth herein; or

 

(k) Verify
calculations, qualify, or otherwise approve Company requests for distributions pursuant to Sections 1(i), 1(j), or
2(a) above.

 

5. Trust
Account Waiver. The Trustee has 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. In the event the Trustee has any Claim against the Company under this Agreement, including,
without limitation, under Section 3(b) or Section 3(c) hereof, the Trustee 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.

 

6. Termination.
This Agreement shall terminate as follows:

 

(a) If
the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable
efforts to locate a successor trustee during which time the Trustee shall act in accordance with this Agreement. At such time that
the Company notifies the Trustee that a successor trustee has been appointed by the Company and has agreed to become subject to
the terms of this Agreement, the Trustee shall transfer the management of the Trust Account to the successor trustee, including
but not limited to the transfer of copies of the reports and statements relating to the Trust Account, whereupon this Agreement
shall terminate; provided, however, that, in the event that the Company does not locate a successor trustee within ninety (90)
days of receipt of the resignation notice from the Trustee, the Trustee may submit an application to have the Property deposited
with any court in the State of New York or with the United States District Court for the Southern District of New York and upon
such deposit, the Trustee shall be immune from any liability whatsoever; or

 

    4

     

    

 

(b) At
such time that the Trustee has completed the liquidation of the Trust Account in accordance with the provisions of Section 1(i)
hereof, and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement shall terminate
except with respect to Section 3(b) and Section 5.

 

7. Miscellaneous.

 

(a) The
Company and the Trustee will each restrict access to confidential information relating to funds being transferred to or from the
Trust Account to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized
persons may have obtained access to such information, or of any change in its authorized personnel. In executing funds transfers,
the Trustee will rely upon all information supplied to it by the Company, including account names, account numbers, and all other
identifying information relating to a beneficiary, beneficiary’s bank, or intermediary bank. Except for any liability arising
out of the Trustee’s gross negligence, fraud or willful misconduct, the Trustee shall not be liable for any loss, liability,
or expense resulting from any error in the information supplied to it or funds transferred based on such information.

 

(b) This
Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York, without giving
effect to conflicts of law principles that would result in the application of the substantive laws of another jurisdiction. The
parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New York, Borough of
Manhattan, for purposes of resolving any disputes hereunder. As to any claim, cross-claim,
or counterclaim in any way relating to this Agreement, each party waives the right to trial by jury.

 

(c) This
Agreement may be executed in several original or facsimile counterparts, each one of which shall constitute an original, and together
shall constitute but one instrument.

 

(d) This
Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Except
for Sections 1(i) and 1(j) (which sections may not be modified, amended or deleted without the affirmative vote of a majority of
the then outstanding shares of Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together
as a single class; provided that no such amendment will affect any Public Stockholder who has otherwise indicated his, her or its
election to convert his, her or its shares of Common Stock in connection with a stockholder vote sought to amend this Agreement,
including a corresponding change to the Company’s Certificate of Incorporation), this Agreement or any provision hereof may
only be changed, amended or modified by a writing signed by each of the parties hereto; provided, however, that no such change,
amendment or modification may be made without the prior written consent of the Representative. The Trustee may require from Company
counsel an opinion as to the propriety of any proposed amendment.

 

(e) Any
notice, consent or request to be given in connection with any of the terms or provisions of this Agreement shall be in writing
and shall be sent by express mail or similar private courier service, by certified mail (return receipt requested), by hand delivery,

Dear Mr. Wolf and Ms. Gonzalez:

 

Pursuant to Section

that the Company has entered into an agreement with [            ] (the “Target Business”)
to consummate a business combination with the Target Business (“Business Combination”) on or about [insert
date]. The Company shall notify you at least 72 hours in advance (or such shorter time as you may agree) of the actual date of
the consummation of the Business Combination (“Consummation Date”). Capitalized terms used herein and not otherwise
defined shall have the meanings set forth in the Trust Agreement.

 

In accordance with
the terms of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account and transfer
the proceeds to a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation Date, all
of the funds held in the trust operating account at JP Morgan Chase Bank, N.A. (the “Trust Operating Account”)
will be immediately available for transfer to the account or accounts that the Company shall direct on the Consummation Date (including
as directed to it by the Representatives with respect to the Deferred Discount). It is acknowledged and agreed that while the funds
are on deposit in the Trust Operating Account awaiting distribution, the Company will not earn any interest or dividends.

 

On the Consummation
Date (i) counsel for the Company shall deliver to you written notification that the Business Combination has been consummated,
or will be consummated substantially concurrently with your transfer of funds to the accounts as directed by the Company (the “Notification”)
and (ii) the Company shall deliver to you (a) [an affidavit] [a certificate] by the Chief Executive Officer, which verifies that
the Business Combination has been approved by a vote of the Company’s stockholders, if a vote is held and (b) joint written
instructions from the Company and the Representative with respect to the transfer of the funds held in the Trust Account, including
payment of amounts owed to Public Stockholders who have properly exercised their conversion rights and payment of the Deferred
Discount to the Underwriters from the Trust Account (“Instruction Letter”). You are hereby directed and authorized
to transfer the funds held in the Trust Account immediately upon your receipt of the Notification and the Instruction Letter, in
accordance with the terms of the Instruction Letter. In the event that certain deposits held in the Trust Account may not be liquidated
by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company shall direct you as
to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company. Upon the
distribution of all the funds in the Trust Account, your obligations under the Trust Agreement shall be terminated.

 

In the event that the
Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified you on
or before the original Consummation Date of a new Consummation Date, then upon receipt by you of written instructions from the
Company, the funds held in the Trust Account shall be reinvested as provided in the Trust Agreement on the business day immediately
following the Consummation Date as set forth in such notice as soon thereafter as possible.
