Agreement) (or $236,900,000 if the Underwriter’s over-allotment option is exercised in full) and the proceeds from any loans in
connection with an Extension (as defined below), if any, will be delivered to the Trustee to be deposited and held in a segregated trust

and concurrently with the consummation of the Business Combination (as defined below) (the “Deferred Discount”);
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.

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. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion

(b)            Manage,
supervise and administer the Trust Account subject to the terms and conditions set forth herein;

a timely manner, upon the written instruction of the Company, invest and reinvest the Property solely in United States government securities
within the meaning of Section 2(a)(16) of the Investment Company Act of 1940, as amended, having a maturity of 185 days or less,
or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 promulgated
under the Investment Company Act of 1940, as amended (or any successor rule), which invest only in direct U.S. government treasury obligations,
as determined by the Company; it being understood that the Trust Account will earn no interest while account funds are uninvested awaiting
the Company’s instructions hereunder; while account funds are invested or uninvested, 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 Underwriter of all communications received by the Trustee with respect to any Property requiring action by
the Company;


 


(f)            Supply
any necessary information or documents as may be requested by the Company (or its authorized agents) in connection with the Company’s
preparation of the tax returns relating to assets held in the Trust Account;


 


(g)           Participate
in any plan or proceeding for protecting or enforcing any right or interest arising from the Property if, as and when instructed by the
Company to do so;


 


(h)           Render
to the Company monthly written statements of the activities of, and amounts in, the Trust Account reflecting all receipts and disbursements
of the Trust Account;


 


(i)            Commence
liquidation of the Trust Account only after and promptly after (x) receipt of, and only in accordance with the terms of, a letter
from the Company (“Termination Letter”) in a form substantially similar to that attached hereto as either Exhibit A
or Exhibit B, as applicable, signed on behalf of the Company by its Chief Executive Officer, Chief Financial Officer, President,
Executive Vice President, Vice President, Secretary or Chairman of the board of directors of the Company (the “Board”)
or other authorized officer of the Company, and, in the case of Exhibit A, acknowledged and agreed to by the Underwriter,
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 (less taxes payable and, in the case of Exhibit B, less up to $100,000 of interest income to pay
dissolution expenses), only as directed in the Termination Letter and the other documents referred to therein, or (y) upon the date
which is the latest of (1) 15 months after the closing of the Offering and (2) such later date upon an Extension effectuated
pursuant to the terms hereof 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 (less taxes payable and up to $100,000
of interest income to pay dissolution expenses), shall be distributed to the Public Shareholders of record as of such date;


 


(j)            Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit C
(a “Tax Payment Withdrawal Instruction”), withdraw from the Trust Account and distribute to the Company the
amount of interest earned on the Property requested by the Company to cover any tax obligation owed by the Company as a result of assets
of the Company or interest or other income earned on the Property, which amount shall be delivered directly to the Company by electronic
funds transfer or other method of prompt payment, and the Company shall forward such payment to the relevant taxing authority so long
as there is no reduction in the principal amount per share initially deposited in the Trust Account; provided, however,
that to the extent there is not sufficient cash in the Trust Account to pay such tax obligation, the Trustee shall liquidate such assets
held in the Trust Account as shall be designated by the Company in writing to make such distribution (it being acknowledged and agreed
that any such amount in excess of interest income earned on the Property shall not be payable from the Trust Account). The written request
of the Company referenced above shall constitute presumptive evidence that the Company is entitled to said funds, and the Trustee shall
have no responsibility to look beyond said request;


 






    2 


     


    

 


(k)           Upon
written request from the Company, which may be given from time to time in a form substantially similar to that attached hereto as Exhibit D

on behalf of the Company the amount requested by the Company to be used to redeem Ordinary Shares from Public Shareholders properly submitted
in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association
(A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial business
combination or to redeem 100% of the Ordinary Shares included in the Units sold in the Offering (the “public shares”)
if the Company has not consummated an initial Business Combination within such time as is described in the Company’s amended and
restated memorandum and articles of association or (B) with respect to any other material provisions relating to shareholders’
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;


 


(l)            Upon
receipt of an extension letter (“Extension Letter”) substantially similar to Exhibit E hereto at least
five business days prior to the Deadline, signed on behalf of the Company by an executive officer, and receipt of the dollar amount specified
in the Extension Letter on or prior to the Deadline, follow the instructions set forth in the Extension Letter; and


 


(m)          Not
make any withdrawals or distributions from the Trust Account other than pursuant to Section 1(i), (j) or (k) above.


 


2.            Agreements
and Covenants of the Company. The Company hereby agrees and covenants to:


 


(a)            Give
all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer, Chief
Financial Officer, President, Executive Vice President, Vice President or Secretary. In addition, except with respect to its duties under
Sections 1(i), 1(j) and 1(k) hereof, the Trustee shall be entitled to rely on, and shall be protected in
relying on, any verbal or telephonic advice or instruction which it, in good faith and with reasonable care, believes to be given by any
one of the persons authorized above to give written instructions, provided that the Company shall promptly confirm such instructions in
writing;


 


(b)           Subject
to Section 4 hereof, hold the Trustee harmless and indemnify the Trustee from and against any and all expenses, including
reasonable counsel fees and disbursements, or losses suffered by the Trustee in connection with any action taken by it hereunder and in
connection with any action, suit or other proceeding brought against the Trustee involving any claim, or in connection with any claim
or demand, which in any way arises out of or relates to this Agreement, the services of the Trustee hereunder, or the Property or any
interest earned on the Property, except for expenses and losses resulting from the Trustee’s gross negligence, fraud or willful
misconduct. Promptly after the receipt by the Trustee of notice of demand or claim or the commencement of any action, suit or proceeding,
pursuant to which the Trustee intends to seek indemnification under this Section 2(b), it shall notify the Company in
writing of such claim (hereinafter referred to as the “Indemnified Claim”). The Trustee shall have the right
to conduct and manage the defense against such Indemnified Claim; provided that the Trustee shall obtain the consent
of the Company with respect to the selection of counsel, which consent shall not be unreasonably withheld. The Trustee may not agree to
settle any Indemnified Claim without the prior written consent of the Company, which such consent shall not be unreasonably withheld.
The Company may participate in such action with its own counsel;


 


(c)           Pay
the Trustee the fees set forth on Schedule A hereto, including an initial acceptance fee, annual administration fee, and transaction
processing fee which fees shall be subject to modification by the parties from time to time. It is expressly understood that the Property
shall not be used to pay such fees unless and until it is distributed to the Company pursuant to Sections 1(i) through
1(j) hereof. The Company shall pay the Trustee the initial acceptance fee and the first annual administration fee at the consummation
of the Offering. The Company shall not be responsible for any other fees or charges of the Trustee except as set forth in this Section 2(c),
Schedule A and as may be provided in Section 2(b) hereof;


 


(d)           In
connection with any vote of the Company’s shareholders regarding a merger, share exchange, asset acquisition, share 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 shareholder meeting verifying the vote of such
shareholders regarding such Business Combination;


 






    3 


     


    

 


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


 


(f)            Unless
otherwise agreed between the Company and the Underwriter, ensure that any Instruction Letter (as defined in Exhibit A) delivered
in connection with a Termination Letter in the form of Exhibit A expressly provides that the Deferred Discount is paid directly
to the account or accounts directed by the Underwriter prior to any transfer of the funds held in the Trust Account to the Company or
any other person;


 


(g)           Instruct
the Trustee to make only those distributions that are permitted under this Agreement, and refrain from instructing the Trustee to make
any distributions that are not permitted under this Agreement; and


 


(h)           Within
four (4) business days after the Underwriter exercises the over-allotment option (or any unexercised portion thereof) or such over-allotment
option expires, provide the Trustee with a notice in writing of the total amount of the Deferred Discount.


 


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

(b)           Take
any action with respect to the Property, other than as directed in Section 1 hereof, and the Trustee shall have no liability
to any third party except for liability arising out of the Trustee’s gross negligence, fraud or willful misconduct;


 


(c)           Institute
any proceeding for the collection of any principal and income arising from, or institute, appear in or defend any proceeding of any kind
with respect to, any of the Property unless and until it shall have received instructions from the Company given as provided herein to
do so and the Company shall have advanced or guaranteed to it funds sufficient to pay any expenses incident thereto;


 


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


 


(e)            Assume
that the authority of any person designated by the Company to give instructions hereunder shall not be continuing unless provided otherwise
in such designation, or unless the Company shall have delivered a written revocation of such authority to the Trustee;


 


(f)            The
other parties hereto or to anyone else for any action taken or omitted by it, or any action suffered by it to be taken or omitted, in
good faith and in the Trustee’s best judgment, except for the Trustee’s gross negligence, fraud or willful misconduct. The
Trustee may rely conclusively and shall be protected in acting upon any order, notice, demand, certificate, opinion or advice of counsel
(including counsel chosen by the Trustee, which counsel may be the Company’s counsel), statement, instrument, report or other paper
or document (not only as to its due execution and the validity and effectiveness of its provisions, but also as to the truth and acceptability

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;


 






    4

to the Company documenting the taxes payable by the Company, if any, relating to any interest income earned on the Property;


 


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


 


(k)           Verify
calculations, qualify or otherwise approve the Company’s written requests for distributions pursuant to Sections 1(i), 1(j) or
1(k) hereof.


 


4.            Trust
Account Waiver. The Trustee has no right of set-off or any right, title, interest or claim of any kind (“Claim”)
to, or to any monies in, the Trust Account, and hereby irrevocably waives any Claim to, or to any monies in, the Trust Account that it
may have now or in the future. In the event the Trustee has any Claim against the Company under this Agreement, including, without limitation,
under Section 2(b) or Section 2(c) hereof, the Trustee shall pursue such Claim solely against
the Company and its assets outside the Trust Account and not against the Property or any monies in the Trust Account.


 


5.            Termination.
This Agreement shall terminate as follows:


 


(a)           If
the Trustee gives written notice to the Company that it desires to resign under this Agreement, the Company shall use its reasonable efforts
to locate a successor trustee, pending which the Trustee shall continue to act in accordance with this Agreement. At such time that the
Company notifies the Trustee that a successor trustee has been appointed and has agreed to become subject to the terms of this Agreement,
the Trustee shall transfer the management of the Trust Account to the successor trustee, including but not limited to the transfer of
copies of the reports and statements relating to the Trust Account, whereupon this Agreement shall terminate; provided, however,
that in the event that the Company does not locate a successor trustee within ninety (90) days of receipt of the resignation notice from
the Trustee, the Trustee may submit an application to have the Property deposited with any court in the State of New York or with the
United States District Court for the Southern District of New York and upon such deposit, the Trustee shall be immune from any liability
whatsoever; or


 


(b)           At
such time that the Trustee has completed the liquidation of the Trust Account and its obligations in accordance with the provisions of
Section 1(i) hereof and distributed the Property in accordance with the provisions of the Termination Letter, this Agreement
shall terminate except with respect to Section 2(b).


 


6.            Miscellaneous.


 


(a)           The
Company and the Trustee each acknowledge that the Trustee will follow the security procedures set forth below with respect to funds transferred
from the Trust Account. The Company and the Trustee will each restrict access to confidential information relating to such security procedures
to authorized persons. Each party must notify the other party immediately if it has reason to believe unauthorized persons may have obtained

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

of sixty-five percent (65%) of the votes cast of the then outstanding Ordinary Shares and Class B ordinary shares, par value $0.0001

who has properly elected to redeem his or her Ordinary Shares in connection with a shareholder vote to amend this Agreement (A) to
modify the substance or timing of the Company’s obligation to allow redemption in connection with its initial business combination
or to redeem 100% of the public shares if the Company does not complete its initial Business Combination within the time frame specified

Continental Stock Transfer & Trust Company


1 State Street, 30th Floor


New York, New York 10004


Attn: Francis Wolf & Celeste Gonzalez


 


	 	Re:	Trust Account - Termination Letter


 


Dear Mr. Wolf and Ms. Gonzalez:


 


Pursuant to Section 1(i) of
the Investment Management Trust Agreement between Mountain & Co. I Acquisition Corp. (the “Company”)
and Continental Stock Transfer & Trust Company (“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 the Target Business (the “Business Combination”)
on or about [insert date]. The Company shall notify you at least seventy-two (72) hours in advance of the actual date (or
such shorter period as you may agree) of the consummation of the Business Combination (the “Consummation Date”).
Capitalized terms used but not defined herein shall have the meanings set forth in the Trust Agreement.


 


In accordance with the terms
of the Trust Agreement, we hereby authorize you to commence to liquidate all of the assets of the Trust Account, and to transfer the proceeds
to a segregated account held by you on behalf of the Beneficiaries to the effect that, on the Consummation Date, all of the funds held
in the Trust 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 the Underwriter (with respect to the Deferred Discount)).


 


On the Consummation Date (i) counsel
for the Company shall deliver to you written notification that the Business Combination has been consummated, or will be consummated substantially
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 of the Chief Executive Officer, Chief Financial Officer, Co-Executive
Chairman or Vice Chairman, which verifies that the Business Combination has been approved by a vote of the Company’s shareholders,
if a vote is held and (b) a joint written instruction signed by the Company and the Underwriter with respect to the transfer of the
funds held in the Trust Account, including payment of amounts owed to public shareholders who have properly exercised their redemption
rights and payment of the Deferred Discount directly to the account or accounts directed by the Underwriter 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
