subsequently earned thereon) is 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 $9,625,000, or $11,068,750 if the Underwriters’ over-allotment option is exercised in full, is attributable to deferred underwriting discounts and commissions that will

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

Trustee in the United States at J.P. Morgan Chase Bank, N.A. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion or more) in the United States, maintained by the Trustee and at a brokerage institution selected
by the Trustee that is reasonably satisfactory to the Company; 
 (b) Manage, supervise and administer the Trust Account subject to the terms
and conditions set forth herein; 
 (c) In a timely manner, upon the written instruction of the Company, invest and reinvest the Property
solely in United States government securities within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less, or in money market funds meeting the conditions of paragraphs (d)(1),
(d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations, as determined
by the Company; 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; 












 (d) Collect and receive, when due, all interest or other income arising from the Property,
which shall become part of the “Property,” as such term is used herein; 
 (e) Promptly notify the Company and the Representative
of all communications received by the Trustee with respect to any Property requiring action by the Company; 
 (f) Supply any necessary
information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s preparation of the tax returns relating to assets held in the Trust Account; 

(g) Participate in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when
instructed by the Company to do so; 
 (h) Render to the Company monthly written statements of the activities of, and amounts in, the Trust
Account reflecting all receipts and disbursements of the Trust Account; 
 (i) Commence liquidation of the Trust Account only after and
promptly after (x) receipt of, and only in accordance with, the terms of a letter from the Company (“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 its Chief Executive Officer, Chief Financial Officer, President, Executive Vice President, Vice President, Secretary or Chairman of the board of directors of the Company (the
“Board”) or other authorized officer of the Company, and, in the case of Exhibit A, 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 earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to pay dissolution expenses), only as directed in the Termination Letter and
the other documents referred to therein, or (y) upon the date which is, the later of (1) 24 months after the closing of the Offering and (2) such later date as may be approved by the Company’s stockholders in accordance with the
Company’s amended and restated certificate of incorporation if a Termination Letter has not been received by the Trustee prior to such date, in which case the Trust Account shall be liquidated in accordance with the procedures set forth in the
Termination Letter attached as Exhibit B and the Property in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes (less up to $100,000 of interest to
pay dissolution expenses), shall be distributed to the Public Stockholders of record as of such date; 
 (j) Upon written request from the
Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C (a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the
Company the amount of interest earned on the Property requested by the Company to cover any tax obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which amount shall be delivered
directly to the Company by electronic funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority, so long as there is no reduction in the principal amount per share initially
deposited in the Trust Account; provided, however, that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets held in the Trust Account as shall be
designated by the Company in writing to make such distribution (it being acknowledged and agreed that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The written request of the
Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall have no responsibility to look beyond said request; 

  
 2 













 (k) Upon written request from the Company, which may be given from time to time in a form
substantially similar to that attached hereto as Exhibit D (a “Stockholder Redemption Withdrawal Instruction”), the Trustee shall distribute on behalf of the Company the amount requested by the Company to be
used to redeem shares of Common Stock from Public Stockholders properly submitted in connection with a stockholder vote to approve an amendment to the Company’s amended and restated certificate of incorporation to modify the substance or timing
of the Company’s obligation to redeem 100% of shares of Common Stock included in the Units sold in the Offering (the ‘“public shares”) if the Company has not consummated an initial Business Combination within
such time as is described in the Company’s amended and restated certificate of incorporation or with respect to any other material provisions relating to stockholders’ rights or pre-initial Business
Combination activity. The written request of the Company referenced above shall constitute presumptive evidence that the Company is entitled to distribute said funds, and the Trustee shall have no responsibility to look beyond said request; and 

(l) Not make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j)
or (k) above. 
 2. Agreements and Covenants of the Company. The Company hereby agrees and covenants to: 

(a) Give all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer,
Chief Financial Officer, President, Executive Vice President, Vice President or Secretary. In addition, except with respect to its duties under Sections 1(i), 1(j) and 1(k) hereof, 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 reasonable care, believes to be given by any one of the persons authorized above to give written instructions, provided that the
Company shall promptly confirm such instructions in writing; 
 (b) Subject to Section 4 hereof, hold the Trustee
harmless and indemnify the Trustee from and against any and all expenses, including reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in connection with any action,
suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any interest
earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful misconduct. Promptly after the receipt 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 Section 2(b), 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 such consent shall not be unreasonably withheld. The Company may participate in such action
with its own counsel; 
 (c) Pay the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual
administration fee, and transaction processing fee 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 unless and until it is distributed to
the Company pursuant to Sections 1(i) through 1(j) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation of the Offering. The Company shall not be responsible
for any other fees or charges of the Trustee except as set forth in this Section 2(c), Schedule A and as may be provided in Section 2(b) hereof; 

(d) In connection with any vote of the Company’s stockholders regarding a merger, capital stock exchange, asset acquisition, stock
purchase, reorganization or similar business combination involving the Company and one or more businesses (the “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; 

  
 3 













 (e) Provide the Representative with a copy of any Termination Letter(s) and/or any other
correspondence that is sent to the Trustee with respect to any proposed withdrawal from the Trust Account promptly after it issues the same; 

(f) Unless otherwise agreed between the Company and the Representative, ensure that any Instruction Letter (as defined in Exhibit A)
delivered in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid directly to the account or accounts directed by the Representative on behalf of the Underwriters prior to any
transfer of the funds held in the Trust Account to the Company or any other person; 
 (g) Instruct the Trustee to make only those
distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make any distributions that are not permitted under this Agreement; and 

(h) Within four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised portion thereof) or such
over-allotment option expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount. 
 3. Limitations of
Liability. The Trustee shall have no responsibility or liability to: 
 (a) 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; 
 (b) Take
any action with respect to the Property, other than as directed in Section 1 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; 
 (c) 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 it shall have received instructions from the Company given as provided herein to do so and the Company shall have advanced or guaranteed to it funds
sufficient to pay any expenses incident thereto; 
 (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 it, or any action suffered by it to be taken or omitted, in good faith and in 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, which counsel may be the Company’s
counsel), 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 the
Trustee believes, 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; 

  
 4 













 (g) Verify the accuracy of the information contained in the Registration Statement; 

(h) Provide any assurance that any Business Combination entered into by the Company or any other action taken by the Company is as contemplated
by the Registration Statement; 
 (i) File information returns with respect to the Trust Account with any local, state or federal taxing
authority or provide periodic written statements to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property; 

(j) Prepare, execute and file tax reports, income or other tax returns and pay any taxes with respect to any income generated by, and
activities relating to, the Trust Account, regardless of whether such tax is payable by the Trust Account or the Company, including, but not limited to, tax obligations, except pursuant to Section 1(j) hereof; or 

(k) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i),
1(j) or 1(k) hereof. 
 4. 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 2(b) or Section 2(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. 
 5. 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, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the Company notifies the Trustee that a successor trustee has
been appointed 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 
 (b) At such time that the Trustee has completed the liquidation of the Trust Account and
its obligations 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 2(b). 
 6. Miscellaneous. 

(a) The Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds
transferred from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures 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 confidential information, or of any change in its authorized personnel. In executing funds transfers, the Trustee shall 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 or transmission of the funds. 

  
 5 













 (b) This Agreement shall be governed by and construed and enforced in accordance with the
laws of the State of New York. 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. 

(c) This Agreement contains the entire agreement and understanding of the parties hereto with respect to the subject matter hereof. Subject to
Section 6(d) hereof, this Agreement or any provision hereof may only be changed, amended or modified (other than to correct a typographical error) by a writing signed by each of the parties hereto. 

(d) This Agreement or any provision hereof may only be changed, amended or modified pursuant to Section 6(c) hereof with the Consent of
the Stockholders. For purposes of this Section 6(d), the “Consent of the Stockholders” means receipt by the Trustee of a certificate from the inspector of elections of the stockholder meeting certifying that the Company’s
stockholders of record as of a record date established in accordance with Section 213(a) of the Delaware General Corporation Law, as amended (“DGCL”) (or any successor rule), who hold sixty-five percent (65%) or more of all then
outstanding shares of the Common Stock and Class B common stock, par value $0.0001 per share, of the Company voting together as a single class, have voted in favor of such change, amendment or modification. No such amendment will affect any
Public Stockholder who has otherwise indicated his election to redeem his shares of Common Stock in connection with a stockholder vote sought to amend this Agreement to modify the substance or timing of the Company’s obligation to redeem 100%
of the Common Stock if the Company does not complete its initial Business Combination within the time frame specified in the Company’s amended and restated certificate of incorporation. Except for any liability arising out of the Trustee’s
gross negligence, fraud or willful misconduct, the Trustee may rely conclusively on the certification from the inspector or elections referenced above and shall be relieved of all liability to any party for executing the proposed amendment in
reliance thereon. 
 (e) The parties hereto consent to the jurisdiction and venue of any state or federal court located in the City of New
York, State of New York, 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. 

(f) 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 or by electronic mail:

 Re: Trust Account – Termination Letter

(the “Trust Agreement”), this is to advise you that the Company has entered into an agreement with (the “Target Business”) to consummate a business combination with Target Business (the
“Business Combination”) on or about [insert date]. The Company shall notify you at least seventy-two (72) hours in advance of the actual date (or such shorter period as you
may agree) of the consummation of the Business Combination (the “Consummation Date”). Capitalized terms used but not defined herein 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 to 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 JPMorgan Chase Bank, N.A. 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 Representative on behalf of the Underwriters (with respect to the Deferred Discount)). 

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 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) a certificate by the
Chief Executive Officer, Chief Financial Officer, Co-Executive Chairman or Vice Chairman, which verifies that the Business Combination has been approved by a vote of the Company’s stockholders, if a vote
is held and (b) a joint written instruction signed by 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 redemption rights and payment of the Deferred Discount directly to the account or accounts directed by the Representative from the Trust Account (the “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, net of any payments necessary for reasonable unreimbursed expenses related to liquidating 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 the Trustee of written instructions from the Company, the funds held in the Trust Account shall be reinvested as provided in Section 1(c)
of the Trust Agreement on the business day immediately following the Consummation Date as set forth in such notice as soon thereafter as possible.
