Exhibit 10.4


 


PRIVATE
PLACEMENT WARRANTS PURCHASE AGREEMENT


 


THIS
PRIVATE PLACEMENT WARRANTS PURCHASE AGREEMENT, dated as of [●], 2021 (as it may from time to time be amended and including all
exhibits referenced herein, this “Agreement”), is entered into by and between TKB Critical Technologies 1, a Cayman
Islands exempted company (the “Company”), and TKB Sponsor I, LLC, a Delaware limited liability company (the “Purchaser”).


 


WHEREAS,
the Company intends to consummate an initial public offering of the Company’s units (the “Public Offering”),
each unit consisting of one Class A ordinary share, par value $0.0001 per share (each, a “Share”), of the Company
and one-third of one redeemable warrant. Each whole warrant entitles the holder to purchase one Share at an exercise price of $11.50
per Share. The Purchaser has agreed to purchase an aggregate of 4,200,000 warrants (or 4,600,000 warrants in the aggregate to the extent
the over-allotment option in connection with the Public Offering is exercised) (the “Private Placement Warrants”),
each Private Placement Warrant entitling the holder to purchase one Share at an exercise price of $11.50 per Share.


 


NOW
THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt
and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:


 


AGREEMENT


 


Section
1. Authorization, Purchase and Sale; Terms of the Private Placement Warrants.


 


A. Authorization
of the Private Placement Warrants. The Company has duly authorized the issuance and sale of the Private Placement Warrants to
the Purchaser.


 


B. Purchase and Sale of the Private Placement Warrants.




 


On
the date of the consummation of the Public Offering or on such earlier time and date as may be mutually agreed by the Purchaser and the
Company (the “IPO Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase
from the Company, an aggregate of 4,200,000 Private Placement Warrants at a price of $1.50 per warrant for an aggregate purchase price
of $6,300,000 (the “Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company
in accordance with the Company’s wiring instructions at least one business day prior to the IPO Closing Date. On the IPO Closing
Date, the Company shall either, at its option, deliver certificates evidencing the Private Placement Warrants purchased by the Purchaser
on such date duly registered in the Purchaser’s name to the Purchaser, or effect such delivery in book-entry form. On the date
of the consummation of the closing of the over-allotment option in connection with the Public Offering or on such earlier time and date
as may be mutually agreed by the Purchaser and the Company (each such date, an “Over-allotment Closing Date,” and
each Over-allotment Closing Date (if any) and the IPO Closing Date being sometimes referred to herein as a “Closing Date”),
the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, up to an additional 400,000 Private
Placement Warrants, in the same proportion as the amount of the over-allotment option that is exercised, at a price of $1.50 per warrant
for an aggregate purchase price of up to $600,000 (if the over-allotment option in connection with the Public Offering is exercised in
full) (the “Over-allotment Purchase Price”), which shall be paid by wire transfer of immediately available funds to
the Company in accordance with the Company’s wiring instructions at least one business day prior to such Over-allotment Closing
Date. On the Over-allotment Closing Date, upon the payment by the Purchaser of the Over-allotment Purchase Price payable by it by wire
transfer of immediately available funds to the Company, the Company shall either, at its option, deliver certificates evidencing the
Private Placement Warrants purchased by the Purchaser on such date duly registered in the Purchaser’s name to the Purchaser, or
effect such delivery in book-entry form.


 


C. Terms of the Private Placement Warrants.




 


(i) The
Private Placement Warrants shall have their terms set forth in a Warrant Agreement to be entered into by the Company and a warrant agent,
in connection with the Public Offering (the “Warrant Agreement”).


 






    1


     


    

 


(ii) At
or prior to the time of the IPO Closing Date, the Company and the Purchaser shall enter into a registration rights agreement (the “Registration
Rights Agreement”) pursuant to which the Company will grant certain registration rights to the Purchaser relating to the Private
Placement Warrants and the Shares underlying the Private Placement Warrants.


 


Section
2. Representations and Warranties of the Company. As a material inducement to the Purchaser to enter into this Agreement and purchase
the Private Placement Warrants, the Company hereby represents and warrants to the Purchaser (which representations and warranties shall
survive each Closing Date) that:


 


A. Organization
and Corporate Power. The Company is an exempted company duly organized, validly existing and in good standing under the laws of the

Private Placement Warrants will constitute valid and binding obligations of the Company, enforceable in accordance with their terms,

amended prior to completion of the contemplated Public Offering), or any material law, statute, rule or regulation to which the Company
is subject, or any agreement, order, judgment or decree to which the Company is subject, except for any filings required after the date

Section
3. Representations and Warranties of the Purchaser. As a material inducement to the Company to enter into this Agreement and issue

by this Agreement.


 


B. Authorization; No Breach.




 


(i) The
execution, delivery and performance of this Agreement have been duly authorized and approved by the Purchaser. This Agreement constitutes
a valid and binding obligation of the Purchaser, enforceable in accordance with its terms, subject to bankruptcy, insolvency, fraudulent
conveyance, reorganization, moratorium and other laws of general applicability relating to or affecting creditors’ rights and to
general equitable principles (whether considered in a proceeding in equity or law).


 


(ii) The
execution and delivery by the Purchaser of this Agreement and the fulfillment of and compliance with the terms hereof by the Purchaser
does not and shall not as of each Closing Date conflict with or result in a breach by the Purchaser of the terms, conditions or provisions
of any agreement, instrument, order, judgment or decree to which the Purchaser is subject that would materially impact its ability to
perform its obligations hereunder.


 


C. Investment Representations.




 


(i) The
Purchaser is acquiring the Private Placement Warrants and, upon exercise of the Private Placement Warrants, the Shares issuable upon
such exercise (collectively, the “Securities”), for the Purchaser’s own account, for investment purposes only
and not with a view towards, or for resale in connection with, any public sale or distribution thereof.


 


(ii) The
Purchaser is an “accredited investor” as such term is defined in Rule 501(a)(3) of Regulation D of the Securities Act of
1933, as amended (the “Securities Act”), and the Purchaser has not experienced a disqualifying event as enumerated
pursuant to Rule 506(d) of Regulation D under the Securities Act.


 


(iii) The
Purchaser understands that the Securities are being offered and will be sold to it in reliance on specific exemptions from the registration
requirements of the United States federal and state securities laws and that the Company is relying upon the truth and accuracy of, and
the Purchaser’s compliance with, the representations and warranties of the Purchaser set forth herein in order to determine the
availability of such exemptions and the eligibility of the Purchaser to acquire such Securities.


 


(iv) The
Purchaser did not decide to enter into this Agreement as a result of any general solicitation or general advertising within the meaning
of Rule 502(c) under the Securities Act.


 


(v) The
Purchaser has been furnished with all materials relating to the business, finances and operations of the Company and materials relating
to the offer and sale of the Securities which have been requested by the Purchaser. The Purchaser has been afforded the opportunity to
ask questions of the executive officers and directors of the Company. The Purchaser understands that its investment in the Securities
involves a high degree of risk and it has sought such accounting, legal and tax advice as it has considered necessary to make an informed
investment decision with respect to the acquisition of the Securities.


 






    3


     


    

 


(vi) The
Purchaser understands that no United States federal or state agency or any other government or governmental agency has passed on or made
any recommendation or endorsement of the Securities or the fairness or suitability of the investment in the Securities by the Purchaser
nor have such authorities passed upon or endorsed the merits of the offering of the Securities.


 


(vii) The
Purchaser understands that: (a) the Securities have not been and are not being registered under the Securities Act or any state securities
laws, and may not be offered for sale, sold, assigned or transferred unless (1) subsequently registered thereunder or (2) sold in reliance
on an exemption therefrom; and (b) except as specifically set forth in the Registration Rights Agreement, neither the Company nor any
other person is under any obligation to register the Securities under the Securities Act or any state securities laws or to comply with
the terms and conditions of any exemption thereunder. While the Purchaser understands that Rule 144 under the Securities Act is not available
for the resale of securities initially issued by shell companies (other than business combination related shell companies) or issuers
that have been at any time previously a shell company, the Purchaser understands that Rule 144 includes an exception to this prohibition
if the following conditions are met: (i) the issuer of the securities that was formerly a shell company has ceased to be a shell company;
(ii) the issuer of the securities is subject to the reporting requirements of Section 13 or 15(d) of the Securities Exchange Act of 1934,
as amended (the “Exchange Act”); (iii) the issuer of the securities has filed all Exchange Act reports and material
required to be filed, as applicable, during the preceding 12 months (or such shorter period that the issuer was required to file such
reports and materials), other than Form 8-K reports; and (iv) at least one year has elapsed from the time that the issuer filed current
Form 10 type information with the U.S. Securities and Exchange Commission (the “SEC”) reflecting its status as an
entity that is not a shell company.


 


(viii) The
Purchaser has knowledge and experience in financial and business matters, understands the high degree of risk associated with investments
in the securities of companies in the development stage such as the Company, is capable of evaluating the merits and risks of an investment
in the Securities and is able to bear the economic risk of an investment in the Securities in the amount contemplated hereunder for an
indefinite period of time. The Purchaser has adequate means of providing for its current financial needs and contingencies and will have
no current or anticipated future needs for liquidity which would be jeopardized by the investment in the Securities. The Purchaser can
afford a complete loss of its investment in the Securities.

written consent of the other party hereto, other than assignments by the Purchaser to its affiliates (including, without limitation,

Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable

obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such facsimile
or “.pdf” signature page were an original thereof.
