Re: Initial
Public Offering

 

Ladies and Gentlemen:

 

This letter (this “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and between Atlas Crest Investment Corp. IV, a Delaware corporation (the “Company”),
and Cantor Fitzgerald & Co., as representative (the “Representative”) of the several underwriters
(each, an “Underwriter” and collectively, the “Underwriters”), relating to
an underwritten initial public offering (the “Public Offering”), of up to 46,000,000 of the Company’s
units (including up to 6,000,000 units that may be purchased to cover over-allotments, if any) (the “Units”),
each comprised of one share of the Company’s Class A common stock, par value $0.0001 per share (the “Class A
Common Stock”), and one-fourth of one redeemable warrant. Each whole warrant (each, a “Warrant”)
entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment
as described in the Prospectus (as defined below). The Units will be sold in the Public Offering pursuant to a registration statement
on Form S-1 and prospectus (the “Prospectus”) filed by the Company with the U.S. Securities and Exchange
Commission (the “Commission”) and the Units have been approved for listing on the New York Stock Exchange.
Certain capitalized terms used herein are defined in paragraph 11 hereof.

 

In order to induce the Company and the
Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, each of Atlas Crest Investment IV-A LLC and Atlas Crest Investment IV-B LLC (together, the
 “Sponsor”) and the undersigned individuals, each of whom is a member of the Company’s board of
directors and/or management team (each of the undersigned individuals, an “Insider” and collectively, the
 “Insiders”), hereby agrees with the Company as follows:

 

1.                  
The Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination, then
in connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Common Stock (as defined below)
owned by it, him or her in favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it,
him or her in connection with such stockholder approval. If the Company seeks to consummate a proposed Business Combination by
engaging in a tender offer, the Sponsor and each Insider agrees that it, he or she will not sell or tender any shares of Common
Stock owned by it, him or her in connection therewith.

 

2.                   The
Sponsor and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within
24 months from the closing of the Public Offering, or such later period approved by the Company’s stockholders in
accordance with the Company’s amended and restated certificate of incorporation (as it may be amended from time to
time, the “Charter”), the Sponsor and each Insider shall take all reasonable steps to cause the
Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not
more than ten business days thereafter, redeem 100% of the shares of Class A Common Stock sold as part of the Units in the
Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account (as defined below), including interest earned on the funds held in the
Trust Account (which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses),
divided by the number of then outstanding Offering Shares, which redemption will completely extinguish all Public
Stockholders’ rights as stockholders (including the right to receive further liquidating distributions, if any), and
(iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining
stockholders and the Company’s board of directors, liquidate and dissolve, subject in each case to the Company’s
obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. The Sponsor and
each Insider agrees to not propose any amendment to the Charter to modify the substance or timing of the Company’s
obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within the required
time period set forth in the Charter or with respect to any other material provisions relating to stockholders’ rights
or pre-initial business combination activity, unless the Company provides its Public Stockholders with the opportunity to
redeem their Offering Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account
(which interest shall be net of taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the
number of then outstanding Offering Shares.

 

    

     

    

 

The Sponsor and each Insider acknowledges
that it, he or she has no right, title, interest or claim of any kind in or to any monies held in the Trust Account or any other
asset of the Company as a result of any liquidation of the Company with respect to the Founder Shares held by it, him or her. The
Sponsor and each Insider hereby further waives, with respect to any shares of Common Stock held by it, him or her, if any, any
redemption rights it, he or she may have in connection with (A) the consummation of a Business Combination, including, without
limitation, any such rights available in the context of a stockholder vote to approve such Business Combination, or (B) a stockholder
vote to approve an amendment to the Charter to modify the substance or timing of the Company’s obligation to redeem 100%
of the Offering Shares if the Company has not consummated a Business Combination within the time period set forth in the Charter
or with respect to any other material provisions relating to stockholders’ rights or pre-initial business combination activity
or in the context of a tender offer made by the Company to purchase Offering Shares (although the Sponsor, the Insiders and their
respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold
if the Company fails to consummate a Business Combination within the time period set forth in the Charter).

 

3.                  
During the period commencing on the effective date of the Underwriting Agreement and ending 180 days after such date, the
Sponsor and each Insider shall not, other than as permitted in the Amended and Restated Operating Agreement of the Sponsor, as
amended, supplemented or modified, from time to time, without the prior written consent of the Representative, (i) sell, offer
to sell, contract or agree to sell, hypothecate, pledge, grant any option to purchase or otherwise dispose of or agree to dispose
of, directly or indirectly, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position
within the meaning of Section 16 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
and the rules and regulations of the Commission promulgated thereunder, with respect to, any Units, shares of Common Stock (including,
but not limited to, Founder Shares), Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of
Common Stock owned by it, him or her, (ii) enter into any swap or other arrangement that transfers to another, in whole or in part,
any of the economic consequences of ownership of any Units, shares of Common Stock (including, but not limited to, Founder Shares),
Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of Common Stock owned by it, him or her,
whether any such transaction is to be settled by delivery of such securities, in cash or otherwise, or (iii) publicly announce
any intention to effect any transaction specified in clause (i) or (ii). Each of the Insiders and the Sponsor acknowledges and
agrees that, prior to the effective date of any release or waiver, of the restrictions set forth in this paragraph 3 or paragraph
7 below, the Company shall announce the impending release or waiver by press release through a major news service at least two
business days before the effective date of the release or waiver. Any release or waiver granted shall only be effective two business
days after the publication date of such press release. The provisions of this paragraph will not apply if the release or waiver
is effected solely to permit a transfer not for consideration and the transferee has agreed in writing to be bound by the same
terms described in this Letter Agreement to the extent and for the duration that such terms remain in effect at the time of the
transfer. For the avoidance of doubt, none of the provisions of this Section 3 shall apply for any transactions entered
into in connection with the consummation of an initial Business Combination.

 

4.                  
The Sponsor and each Insider, with respect to itself or herself or himself, agrees that if the Company seeks stockholder approval of
a proposed initial Business Combination, then in connection with such proposed initial Business Combination, it, she or he, as
applicable, shall vote all Founder Shares and any shares of Common Stock held by it, her or him, as applicable, in favor of such
proposed initial Business Combination (including any proposals recommended by the Board in connection with such Business
Combination) and not redeem any shares of Common Stock held by it, her or him, as applicable, in connection with such stockholder
approval.

 

    2

     

    

 

5.                   In
the event of the liquidation of the Trust Account upon the failure of the Company to consummate its initial Business
Combination within the time period set forth in the Charter, the Sponsor (which for purposes of clarification shall not
extend to any other shareholders, members or managing managers of the Sponsor) (the “Indemnitor”)
agrees to indemnify and hold harmless the Company against any and all loss, liability, claim, damage and expense whatsoever
(including, but not limited to, any and all legal or other expenses reasonably incurred in investigating, preparing or
defending against any litigation, whether pending or threatened) to which the Company may become subject as a result of any
claim by (i) any third party for services rendered or products sold to the Company or (ii) any prospective target business
with which the Company has entered into a written letter of intent, confidentiality or other similar agreement or Business
Combination agreement (a “Target”); provided, however, that such indemnification of the Company by
the Indemnitor (x) shall apply only to the extent necessary to ensure that such claims by a third party or a Target do not
reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Offering Share and (ii) the actual
amount per Offering Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than
$10.00 per Offering Share is then held in the Trust Account due to reductions in the value of the trust assets, less taxes
payable, (y) shall not apply to any claims by a third party or a Target which executed a waiver of any and all rights to the
monies held in the Trust Account (whether or not such waiver is enforceable) and (z) shall not apply to any claims under the
Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the Securities Act of
1933, as amended. In the event that any such executed waiver by a third party or a
Target is deemed to be unenforceable against such third party or Target, the Sponsor shall not be responsible to the extent
of any liability for such third-party claims. The Indemnitor shall have the right to defend against any such claim
with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of notice of
the claim to the Indemnitor, the Indemnitor notifies the Company in writing that it shall undertake such defense. For
the avoidance of doubt, none of the Company’s officers or directors will indemnify the Company for claims by third
parties, including, without limitation, claims by vendors and prospective target businesses.

 

6.                  
To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 6,000,000
Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor agrees to forfeit,
at no cost, a number of Founder Shares in the aggregate equal to 1,500,000 multiplied by a fraction, (i) the numerator of which
is 6,000,000 minus the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii)
the denominator of which is 6,000,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised
in full by the Underwriters so that the Founder Shares will represent an aggregate of 20.0% of the Company’s issued and outstanding
shares of Class A Common Stock after the Public Offering (not including shares of Class A Common Stock underlying the Warrants
or Private Placement Warrants (as defined below)). The Sponsor further agrees that to the extent that the size of the Public Offering
is increased or decreased, the Company will purchase or sell shares or effect a share repurchase or share capitalization, as applicable,
immediately prior to the consummation of the Public Offering in such amount as to maintain the ownership of the initial shareholders
prior to the Public Offering at 20.0% of its issued and outstanding Capital Shares upon the consummation of the Public Offering.
In connection with such increase or decrease in the size of the Public Offering, then (A) the references to 6,000,000 in the numerator
and denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number
of Public Shares included in the Units issued in the Public Offering and (B) the reference to 1,500,000 in the formula set forth
in the first sentence of this paragraph shall be adjusted to such number of Founder Shares that the Sponsor would have to surrender
to the Company in order for the initial shareholders to hold an aggregate of 20.0% of the Company’s issued and outstanding
shares of Class A Common Stock after the Public Offering (not including shares of Class A Common Stock underlying the Warrants
or Private Placement Warrants).

 

7.                  
The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably
injured in the event of a breach by such Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a),
7(b) and 9, as applicable, of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii)
the non-breaching party shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law
or in equity, in the event of such breach.

 

8.                   (a)           The
Sponsor and each Insider agrees that it, he or she shall not Transfer any Founder Shares (or any shares of Class A Common
Stock issuable upon conversion thereof) until the earlier of (A) one year after the completion of the Company’s initial
Business Combination and (B) subsequent to the Business Combination, (x) if the closing price of the Class A Common Stock
equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the
like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Company’s initial
Business Combination or (y) the date on which the Company completes a liquidation, merger, capital stock exchange,
reorganization or other similar transaction that results in all of the Company’s stockholders having the right to
exchange their shares of Class A Common Stock for cash, securities or other property (the “Founder Shares Lock-up
Period”).

 

    3

     

    

 

(b)               
The Sponsor and each Insider agrees that it, he or she shall not Transfer any Private Placement Warrants (or any share of
Class A Common Stock issued or issuable upon the exercise of the Private Placement Warrants), until 30 days after the completion
of a Business Combination (the “Private Placement Warrants Lock-up Period”, together with the Founder
Shares Lock-up Period, the “Lock-up Periods”).

 

(c)                
Notwithstanding the provisions set forth in paragraphs 7(a) and (b), Transfers of the Founder Shares, Private Placement
Warrants and shares of Class A Common Stock issued or issuable upon the exercise or conversion of the Private Placement Warrants
or the Founder Shares that are held by the Sponsor, any Insider or any of their permitted transferees (that have complied with
this paragraph 7(c)), are permitted (i) to the Company’s officers or directors, any affiliate or family member of any of
the Company’s officers or directors, any affiliate of the Sponsor or to any members of the Sponsor or any of their affiliates;
(ii) in the case of an individual, by gift to a member of such individual’s immediate family or to a trust, the beneficiary
of which is a member of such individual’s immediate family, an affiliate of such individual or to a charitable organization;
(iii) in the case of an individual, by virtue of laws of descent and distribution upon death of such individual; (iv) in the case
of an individual, pursuant to a qualified domestic relations order; (v) by private sales or transfers made in connection with any
forward purchase agreement or any financing transaction or similar arrangement or in connection with the consummation of an initial
Business Combination at prices no greater than the price at which each type of security was originally purchased; (vi) in the event
of the Company’s liquidation prior to the completion of an initial Business Combination; (vii) by virtue of the laws of the
State of Delaware (viii) the Amended and Restated Operating Agreement of the Sponsor, as amended, supplemented or modified, from
time to time ; or (ix) in the event of the Company’s liquidation, merger, capital stock exchange or other similar transaction
which results in all of the Company’s stockholders having the right to exchange their shares of Class A Common Stock for
cash, securities or other property subsequent to the Company’s completion of an initial Business Combination; provided, however,
that in the case of clauses (i) through (ix), these permitted transferees must enter into a written agreement with the Company
agreeing to be bound by the transfer restrictions herein and the other restrictions contained in this Agreement (including provisions
relating to voting, the Trust Account and liquidating distributions).

 

9.                  
The Sponsor and each Insider represents and warrants that it, he or she has never been suspended or expelled from membership
in any securities or commodities exchange or association or had a securities or commodities license or registration denied, suspended
or revoked. Each Insider’s biographical information furnished to the Company (including any such information included in
the Prospectus) is true and accurate in all respects and does not omit any material information with respect to the Insider’s
background. The Sponsor and each Insider’s questionnaire furnished to the Company is true and accurate in all respects. The
Sponsor and each Insider represents and warrants that: it, he or she is not subject to or a respondent in any legal action for,
any injunction, cease-and-desist order or order or stipulation to desist or refrain from any act or practice relating to the offering
of securities in any jurisdiction; it, he or she has never been convicted of, or pleaded guilty to, any crime (i) involving fraud,
(ii) relating to any financial transaction or handling of funds of another person, or (iii) pertaining to any dealings in any securities
and it, he or she is not currently a defendant in any such criminal proceeding.

 

10.                 Except
as disclosed in the Prospectus, neither the Sponsor nor any officer, nor any affiliate of the Sponsor or any officer, nor any
director of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee, non-cash
payments, monies in respect of any repayment of a loan or other compensation prior to, or in connection with any services
rendered in order to effectuate, the consummation of the Company’s initial Business Combination (regardless of the type
of transaction that it is), other than the following, none of which will be made from the proceeds held in the Trust Account
prior to the completion of the initial Business Combination: repayment of a loan and advances up to an aggregate of $300,000
made to the Company by the Sponsor to cover offering-related and organizational expenses; payment to an affiliate of the
Sponsor for certain office space, secretarial and administrative support as may be reasonably required by the Company for a
total of $10,000 per month; cash compensation to an affiliate of the Sponsor, for any financial advisory, placement agency or
other similar investment banking services that such affiliate may provide to our company, in connection with our initial
Business Combination, including, but not limited to, the Marketing Fee (as defined in the Prospectus) payable to the
Representative and an affiliate of the Sponsor, upon the consummation of our initial business combination, and reimbursement
to such affiliate for any out-of-pocket expenses incurred by it in connection with the performance of such services;
reimbursement for any reasonable out-of-pocket expenses related to identifying, investigating, negotiating and consummating
an initial Business Combination, and repayment of non-interest bearing loans which may be made by the Sponsor or an affiliate
of the Sponsor or certain of the Company’s officers and directors at their express option, but not obligation, to
finance transaction costs in connection with an intended initial Business Combination, provided, that, if the Company does
not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used
by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment. The Company agrees that the Sponsor has the right to loan the Company the first $1,500,000 that the Company decides to borrow by prior
to the Business Combination for working capital needs on substantially the same terms as the existing promissory note between them except
that any amounts drawn thereunder would only be due upon the closing of our initial business combination. In addition the it is agreed
that the Sponsor may convert up to $1,500,000 borrowed into warrants that have the same terms as the Private Placement Warrants at $1.50
per warrant. Such warrants would be identical to the Private Placement Warrants (as defined below),
including as to exercise price, exercisability and exercise period.

 

    4

     

    

 

11.

without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this

consents to being named in the Prospectus as an officer and/or director of the Company.

This Investment Management
Trust Agreement (this “Agreement”) is made effective as of [●], 2021, by and between Atlas Crest

Stock”), and one-fourth 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 “Offering”), has been
declared effective as of the date hereof by the U.S. Securities and Exchange Commission; and

 

WHEREAS, the Company
has entered into an Underwriting Agreement (the “Underwriting Agreement”) with Cantor Fitzgerald &
Co. as the representative (the “Representative”) of the several underwriters (the “Underwriters”)
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
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 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;

 

(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 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.

Limitations of Liability. The Trustee shall have no responsibility or liability to:

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

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;

 

(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, 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.

Pursuant to Section
