WHEREAS, the Company
has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Cantor Fitzgerald &

named therein; and


 


WHEREAS, as described
in the Prospectus, $400,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as defined in
the Underwriting Agreement) (or $460,000,000, if the Underwriters’ over-allotment option is exercised in full) 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 Common Stock included in the Units issued in the
Offering as hereinafter provided (the amount to be delivered to the Trustee (and any interest 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”); 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

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 in the United States at J.P. Morgan Chase Bank, N.A., 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;

maturity of 185 days or less, or in money market funds meeting the conditions of Rule 2a-7(d) 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 a Termination
Letter in a form substantially similar to the attached hereto as 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
that may be released to the Company to pay dissolution expenses), only as directed in the Termination Letter and the other documents
referred to therein, or (y) 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 that may be released to the Company 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, 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; 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 per share 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 (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;


 


(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 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 ability of Public Stockholders to seek redemption in connection with an initial Business Combination or amendments to the
Company’s amended and restated certificate of incorporation prior thereto or 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 clause (y) of Section 1(i) of the Agreement. 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 Sections 1(i), (j)
or (k) above.


 






    2


     


    

 


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), (j) and (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 the closing of the Business Combination (defined below).
The Company shall pay the Trustee the initial acceptance 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
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;


 


(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; and


 


(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.

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

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


 


(e)

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;


 


(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)

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, any 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), (j) or (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 Sections 2(b) or (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.


 






    4


     


    

 


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 (which section may not be amended under any circumstances) 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. 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; provided, however, that no such
change, amendment or modification to Sections 1(i), 2(f) or Exhibit A may be made without the prior written
consent of the Representative.


 


(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



 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section
1(i) of the Investment Management Trust Agreement between Atlas Crest Investment Corp. IV (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of ________, 2021 (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 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 J.P. Morgan Chase Bank, N.A., 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 operating 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) a certificate by the Chief Executive Officer, Chief Financial Officer or 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
(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.
