(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; the
Trustee may not invest in any other securities or assets, it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting the Company’s instructions hereunder; 

(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)    As promptly as practicable notify 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

 (h)    Render to the Company monthly written statements of the

(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, President, Chief Financial Officer, Secretary or Chairman of the board of directors of the Company (the “Board”) or other authorized officer of the Company, and complete the liquidation of the Trust
Account and distribute the Property in the Trust Account (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses), including interest earned on funds held in the Trust Account and not previously released to
the Company to pay its taxes, only as directed in the Termination Letter and the other documents referred to therein, or (y) upon the date which is the later of (i) 24 months (or 30 months if the Company has executed a letter of intent,
agreement in principle or definitive agreement within such 24 months period) after the closing of the Offering and (ii) such later date as may be approved by the Company’s stockholders in accordance with the


  
 -2- 








 
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 (less up to $100,000 of interest that may be released to the Company to pay dissolution expenses),
including interest earned on funds held in the Trust Account and not previously released to the Company to pay its taxes, shall be distributed to the Public Stockholders of record as of such date; provided, however, that in the event
the Trustee receives a Termination Letter in a form substantially similar to Exhibit B hereto, or if the Trustee begins to liquidate the Property because it has received no such Termination Letter by the date specified in clause (y) of
this Section 1(i), the Trustee shall keep the Trust Account open until twelve (12) months following the date the Property has been distributed to the Public Stockholders; 

(j)    Upon written request from the Company, which may be given from time to time in a form substantially similar to

obligation owed by the Company as a result of assets of the Company or interest or other income earned on the Property, which such payment the Company shall forward to the relevant taxing authority; 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; provided,
further, that if the tax to be paid is a franchise tax, the written request by the Company to make such distribution shall be accompanied by a copy of the franchise tax bill for the Company and a written statement from the principal financial
officer of the Company setting forth the actual amount payable. 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; 
 (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 to the Public Stockholders of record as of such date (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 its public shares of Common Stock 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. 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.

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 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, or its representatives’, 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; provided, further that the Company may conduct and manage the defense against any Indemnified Claim if the Trustee does not promptly take reasonable steps to mount such a
defense. The Trustee may not agree to settle any Indemnified Claim without the prior written consent of the Company. The Company may participate in any such action with its own counsel; 

(c)    Pay the Trustee the fees set forth on Schedule A hereto, including an initial set-up 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 set-up fee and the first annual
administration fee at the consummation of the Offering. The Trustee shall refund to the Company the annual administration fee (on a pro rata basis) with respect to any period after the liquidation of the Trust Account. 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

elections for the stockholder meeting verifying the vote of such stockholders regarding such Business Combination;

 (f)    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 

(g)    Within four (4) business days after the Underwriters exercise the over-allotment option (or any unexercised
portion thereof) or such over-allotment expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount, which shall in no event be less than $14,000,000.

 (d)    Refund any depreciation in
principal of any Property; 
 (e)    Assume that the authority of any person designated by the Company to give

(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 , or its representatives’, 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; 

  
 -5-

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) and 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 and Replacement of Trustee. 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 and any other
reasonable transfer requests that the Company may make, 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

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, or its representatives’, 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. 
 (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. 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. 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)    Sections 1(i) and 1(k) hereof may only be changed, amended or modified pursuant to
Section 6(c) hereof with the Consent of the Stockholders, it being the specific intention of the parties hereto that each of the Company’s stockholders is, and shall be, a third party beneficiary of this
Section 6(d) with the same right and power to enforce this Section 6(d) as the other parties hereto. 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 either (i) 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, or (ii) the Company’s stockholders of record as of the record date 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 delivered to such entity a signed writing approving such
change, amendment or modification. No such amendment will affect any Public Stockholder who has otherwise indicated his election to redeem his share of Common Stock in connection with a stockholder vote sought to amend Sections 1(i) or
1(k) of this Agreement. Except for any liability arising out of the Trustee’s, or its representatives’, 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, County 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.

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 facsimile transmission:

the actual date 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
on [·], and to transfer the proceeds into the trust checking account at J.P. Morgan Chase Bank, N.A. to the effect that, on the
Consummation Date, all of the funds held in the Trust Account will be immediately available for transfer to the account or accounts that the Company shall direct on the Consummation Date. It is acknowledged and agreed that while the funds are on
deposit in the trust checking account at J.P. Morgan Chase Bank, N.A. 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 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] of

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)
