INVESTMENT
MANAGEMENT TRUST AGREEMENT


 


This
Investment Management Trust Agreement (this “Agreement”) is made effective as of October 26, 2021 by and between
TKB Critical Technologies 1, a Cayman Islands exempted company (the “Company”), and Continental Stock Transfer & Trust Company, a New York limited purpose trust company (the “Trustee”).


 


WHEREAS,
the Company’s registration statement on Form S-1, File No. 333-260167 (the “Registration Statement”)
and prospectus (the “Prospectus”) for the initial public offering (the
“Offering”) of the Company’s units (the “Units”), each of which consists
of one Class A ordinary share, par value $0.0001 per share (the “Ordinary Shares”), and one-half of one
redeemable warrant, each whole warrant entitling the holder thereof to purchase one Ordinary Share, 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 Jefferies LLC, as
representative (the “Representative”) of the several underwriters (the “Underwriters”)
named therein; and


 


WHEREAS, as described in the
Prospectus, $204,000,000 of the gross proceeds of the Offering and sale of the Private Placement Warrants (as defined in the Underwriting
Agreement) (or $234,600,000 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 Ordinary Shares 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 shareholders for whose benefit the Trustee shall hold the Property will be referred to as the “Public Shareholders,”
and the Public Shareholders and the Company will be referred to together as the “Beneficiaries”);


 


WHEREAS, pursuant to the Underwriting Agreement, a
portion of the Property equal to $7,750,000, or $8,800,000 if the Underwriters’ over-allotment option is exercised in full, is
attributable to deferred underwriting discounts and commissions that will be payable by the Company to the Underwriters upon 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.


 


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. (or at another U.S. chartered commercial bank with consolidated assets of $100 billion
or more) in the United States, 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 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; and while
account funds are invested or uninvested the Trustee may earn bank credits or other consideration;

 




     

     


    

 


(d) Collect
and receive, when due, all principal, 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 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 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 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 later of (1) 15 months after the closing of the Offering and (2) such later date as may be approved by the Company’s
shareholders in accordance with the Company’s amended and restated memorandum and articles of association 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 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 Ordinary 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
Tax Payment Withdrawal Instruction 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 (a “Shareholder Redemption Withdrawal Instruction”), the Trustee shall distribute to the Public Shareholders
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 our initial
Business Combination (defined below) 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;
and

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


 


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

all instructions to the Trustee hereunder in writing, signed by the Company’s Chairman of the Board, Chief Executive Officer or
Chief Financial Officer. 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 documented 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;


 


(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;


 


(f) Unless
otherwise agreed between the Company and the Representative, 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 Representative on behalf of the Underwriters prior to any transfer of the funds held in the
Trust Account to the Company or any other person;


 




    	3



     


    

 


(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 Underwriters exercise 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:


 


(a) 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 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
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

(h) Provide

(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


 




    	4



     


    

 


(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, during which time 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 by the Company 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
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.

    Letter


 


Dear
Mr. Wolf and Ms. Gonzalez:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between TKB Critical Technologies 1 (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 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 Representative on behalf of the Underwriters (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 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 or Chief Financial Officer, 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 Representative 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 Representative from the Trust Account (the “Instruction Letter”).
You are hereby directed and authorized to transfer the funds held in the Trust Account immediately upon your receipt of the Notification
and the Instruction Letter, in accordance with the terms of the Instruction Letter. In the event that certain deposits held in the Trust
Account may not be liquidated by the Consummation Date without penalty, you will notify the Company in writing of the same and the Company
shall direct you as to whether such funds should remain in the Trust Account and be distributed after the Consummation Date to the Company.
Upon the distribution of all the funds, net of any payments necessary for reasonable unreimbursed expenses related to liquidating the
Trust Account, your obligations under the Trust Agreement shall be terminated.


 


In
the event that the Business Combination is not consummated on the Consummation Date described in the notice thereof and we have not notified
you on or before the original Consummation Date 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.

Dear
Mr. Wolf and Ms. Gonzalez:


 


Pursuant
to Section 1(i) of the Investment Management Trust Agreement between TKB Critical Technologies 1 (the “Company”)
and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of ____________, 2021 (the

to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity. As such, you are
hereby directed and authorized to transfer (via wire transfer) such funds promptly upon your receipt of this letter to a segregated account
held by you on behalf of the Beneficiaries.
