 (e) Promptly notify the Company and Morgan Stanley & Co. LLC of

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, 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, including interest not previously released to the Company to pay its taxes, only as directed in the Termination

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;
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 so long as there is no reduction in the principal amount initially deposited in the Trust Account; 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 from the State of Delaware 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 (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); 
 (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, the Trustee shall distribute to the Public Stockholders of record as of such date the amount requested by the Company to be used to

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 or (ii) with respect to any other provision 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.

Officer, Chief Financial Officer 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 such
written instructions and, further, 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 

  
 3

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 $10,500,000; and 

(h) Unless otherwise agreed between the Company and Morgan Stanley & Co. LLC, 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 Morgan Stanley & Co. LLC prior to any transfer of
the funds held in the Trust Account to the Company or any other person.

good faith and in the Trustee’s reasonable 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

hereof; or 
 (l) Verify calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to

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 













 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

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. 
 (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.

Section 6 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 as the other parties hereto. For purposes of this Section 6(d), the “Consent of the
Stockholders” means receipt by the Trustee of a 

  
 6 













 
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

common stock, par value $0.00001 per share, 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 share of Common Stock in
connection with a stockholder vote sought to amend this Agreement. 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.

Gentlemen:

Combination”) on or about                 , 20    . The Company shall notify you at least forty-eight (48) hours in advance of the
actual date of the consummation of the Business Combination (or such shorter time period as you may agree) (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                 , 20    , and to transfer the proceeds into 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 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
Morgan Stanley & Co. LLC (with respect to the Deferred Discount)). It is acknowledged and agreed that while the funds are on deposit in the trust checking account at Bank of America, National Association, 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 the Chief Executive Officer of the Company, 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 written
instruction signed by the Company with respect to the transfer of the funds held in the Trust Account, including payment of the Deferred Discount 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 

  
 A-1 













 
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 written instruction as soon thereafter as possible.
