AMENDED AND RESTATED FORWARD PURCHASE AGREEMENT


 


This Amended and Restated
Forward Purchase Agreement (this “Agreement”) is entered into as of August 13, 2021, by and among TKB Critical Technologies
1, a Cayman Islands exempt company (the “Company”), and the other entities listed on the signature pages hereto. (collectively,
the “Purchaser”).


 


WHEREAS, the Company
was incorporated for the purpose of effecting a merger, stock exchange, asset acquisition, stock purchase, reorganization or similar business
combination with one or more businesses (a “Business Combination”);


 


WHEREAS, the Company
has confidentially filed with the U.S. Securities and Exchange Commission (the “SEC”) a registration statement on Form
S-1 (the “Registration Statement ”) for its initial public offering (“IPO”) of units (the “Public
Units”) at a price of $10.00 per Public Unit, each comprised of one Class A ordinary share of the Company, par value $0.0001
per share (the “Class A Share(s)”), and one-third of one redeemable warrant, where each whole redeemable warrant is
exercisable to purchase one Class A Share at an exercise price of $11.50 per share (the “Warrant(s)”);


 


WHEREAS, following
the closing of the IPO (the “IPO Closing”), the Company will seek to identify and consummate a Business Combination;


 


WHEREAS, the parties
wish to enter into this Agreement, pursuant to which, immediately prior to the closing of the Company’s initial Business Combination
(the “Business Combination Closing”), and subject to the terms and conditions set forth herein, the Company shall issue
and sell, and the Purchaser shall purchase, on a private placement basis, Class A Shares and Warrants, each on the terms and conditions
set forth herein;


 


NOW, THEREFORE, in
consideration of the premises, representations, warranties and the mutual covenants contained in this Agreement, and for other good and
valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:


 


		1.	Sale and Purchase.



 


		(a)	Forward Purchase Securities.



 


(i) Subject
to the terms and conditions set forth herein, the Company shall issue and sell to the Purchaser, at the Company’s option, up to,
and the Purchaser shall purchase from the Company, subject to the conditions set forth herein, up to, (i) a number of Class A Shares
equal to 20% of the Class A Shares sold in the IPO (the “Forward Purchase Shares”) and (ii) a
number of Warrants equal to 20% of the Warrants sold in the IPO (the “Forward Purchase Warrants”, together with the
Forward Purchase Shares, the “Forward Purchase Securities”), for a purchase price of $10.00 (the “FPS Purchase
Price”) for (1) one Class A Share plus (ii) the fraction of a Warrant included in the Public Units (which shall not be less
than 1⁄4 Warrant), for an aggregate purchase price not to exceed $40,000,000 ($46,000,000 if the over-allotment option is exercised
in full). To the extent the number of Forward Purchase Securities to be purchased by Purchaser under this Agreement, together with any
other Class A Shares of the Company held directly or indirectly by the Purchaser, will result in the Purchaser beneficially owning more
than 9.9% of the Class A Shares of the Company (or such other entity as may be the continuing public company following the Business Combination),
as determined pursuant to Rule 13d--3 under the Securities Exchange Act of 1934, as amended, the Purchaser shall have the right to limit
its purchase obligations under this Agreement to such number of Forward Purchase Securities as would not result in its beneficial ownership
exceeding 9.9%, as determined above.


 






     


     


    

 


(ii) The
Company may, in its discretion, determine whether to offer to the Purchaser the right to purchase any Forward Purchase Securities, provided
that, in the event the Company determines to issue equity securities for cash in a private placement transaction to provide additional
equity financing in connection with the completion of the Business Combination (other than to an affiliates of the Company or the equity
holders of the target company in the Business Combination) (a “PIPE Transaction”) and Class A Shares are offered in
the PIPE Transaction at a price per share less than $10 per share, the FPS Purchase Price shall be adjusted to such lower price.


 


(iii) The
Forward Purchase Shares will have the same terms as the Class A Shares sold in the IPO and the Forward Purchase Warrants will have the
same terms as the Warrants sold in the IPO, except the Forward Purchase Securities are being offered and sold pursuant to an exemption
from the registration requirements of the Securities Act of 1933, as amended the “Securities Act”). The Forward Purchase
Warrants will be subject to the terms and conditions of the Warrant Agreement to be entered into between the Company and Continental Stock
Transfer & Trust Company, as Warrant Agent, in connection with the IPO (the “Warrant Agreement”) and will entitle
the holder thereof to purchase one Class A Share at a price of $11.50 per share, subject to adjustment as described in the Warrant Agreement,
and only whole Warrants will be exercisable. The Warrants will become exercisable on the later of 30 days after the Business Combination
Closing or 12 months from the closing of the IPO and will expire five years after the Business Combination Closing or earlier upon redemption
or the liquidation of the Company, as described in the Warrant Agreement.


 


(iv) As
soon as reasonably practicable, but in no event less than ten (10) Business Days prior to the Company’s entry into a definitive
agreement for the Business Combination (the “Business Combination Agreement”), the Company shall provide the Purchaser
with a written notice (the “Company Notice”) that (i) it intends to enter into a the Business Combination Agreement,
together with a draft of the Business Combination Agreement, and such other information as the Purchaser may reasonably request so that
the Purchaser may seek the approval of investment committee and any other internal approvals required to consummate the purchase of the
Forward Purchase Securities hereunder (collectively, “Investment Committee Approval”), and (iii) specifying the anticipated
date of the Business Combination Closing, the number of Forward Purchase Securities the Company is offering to sell to the Purchaser (which
will not be less than the number of Forward Purchase Securities specified in Section 1(a)(ii) above and which will not exceed the number
of Forward Purchase Securities that Purchaser has agreed to purchase pursuant to Section 1(a)(i)), the aggregate purchase price for the
Forward Purchase Securities (the “Aggregate FPS Purchase Price”) and instructions for wiring the Aggregate FPS Purchase
Price to an account designated by the Company.

(v) The
decision whether to approve the purchase of the Forward Purchase Securities shall rest in the sole discretion of the Investment Committee.
As promptly as practical after receipt of the Company Notice, the Purchaser shall provide the Company with a written notice (the “Purchaser
Notice”) as to whether or not the Investment Committee has provided the Investment Committee Approval. The delivery of a Purchaser
Notice stating that the Investment Committee has not approved the purchase of the Forward Purchase Securities on the terms and conditions
set forth in the Company Notice shall constitute a rejection by Purchaser of the Company’s offer to sell the Forward Purchase Securities
and Purchaser shall have no obligation to purchase the Forward Purchase Securities. In the event the Purchaser does not provide the Purchaser
Notice within five (5) Business Days after receipt of the Company Notice and the information requested pursuant to Section 1(a)(iv), the
Investment Committee shall be deemed not to have approved the purchase of the Forward Purchase Securities and the Company shall have no
obligation to sell the Forward Purchase Securities to the Purchaser and the Purchaser shall have no obligation to purchase the Forward
Purchase Securities. The delivery of a Purchaser Notice stating that the Investment Committee has approved the purchase of the Forward
Purchase Securities on the terms and conditions set forth in the Company Notice shall constitute the binding obligation of the Purchaser
to purchase the Forward Purchase Securities on the terms and conditions set forth in the Company Notice, subject to the terms and conditions
of this Agreement.


 


(vi) Provided
the Purchaser is under an obligation to purchase the Forward Purchase Securities, at least two (2) Business Days before the anticipated
date of the Business Combination Closing specified in the Company Notice, the Purchaser shall deliver the Aggregate FPS Purchase Price
in cash via wire transfer to the account specified in such notice pending the Business Combination Closing. If the Business Combination
Closing does not occur within thirty (30) days after the Purchaser delivers the Aggregate FPS Purchase Price, the Company shall return
to the Purchaser the Aggregate FPS Purchase Price, provided that the return of the Aggregate FPS Purchase Price shall not terminate this
Agreement or otherwise relieve either party of any of its obligations hereunder and the Company may provide a subsequent Company Notice
pursuant to this Section 1(a)(ii). For the purposes of this Agreement, “Business Day” means any day, other than a Saturday
or a Sunday, that is neither a legal holiday nor a day on which banking institutions are generally authorized or required by law or regulation
to close in the City of New York, New York.


 


(vii) The
closing of the sale of the Forward Purchase Securities (the “FPS Closing”) shall be held on the same date and immediately
prior to the Business Combination Closing (such date being referred to as the “Closing Date”). At the FPS Closing,
the Company will issue to the Purchaser the Forward Purchase Securities, each registered in the name of the Purchaser, against (and concurrently
with) release of the Aggregate FPS Purchase Price to the Company.


 


		(b)	Delivery of Forward Purchase Securities.



 


(i) The
Company shall register the Purchaser as the owner of the Forward Purchase Securities purchased by the Purchaser hereunder with the Company’s
transfer agent by book entry on or promptly after (but in no event more than two (2) Business Days after) the date of the FPS Closing.

(ii) Each
register and book entry for the Forward Purchase Securities shall contain a notation, and each certificate (if any) evidencing the Securities

(c) Legend
Removal. If the Securities are eligible to be sold without restriction under, and without the Company being in compliance with the
current public information requirements of, Rule 144 under the Securities Act, then at the Purchaser’s request, the Company will
cause the Company’s transfer agent to remove the legend set forth in Section 1(c)(ii). In connection therewith, if required
by the Company’s transfer agent, the Company will promptly cause an opinion of counsel to be delivered to and maintained with its
transfer agent, together with any other authorizations, certificates and directions required by the transfer agent that authorize and
direct the transfer agent to transfer such Securities without any such legend; provided, however, that the Company will
not be required to deliver any such opinion, authorization or certificate or direction if it reasonably believes that removal of the legend
could result in or facilitate transfers of Securities in violation of applicable law.


 


(d) Registration

in the Registration Statement and filed as an exhibit thereto and shall constitute “Registrable Securities” thereunder.

indenture or mortgage to which it is a party or by which it is bound, (iv) under any lease, agreement, contract or purchase order to which

a view to the resale or distribution of any part thereof, and that the Purchaser has no present intention of selling, granting any participation
in, or otherwise distributing the same in violation of law. By executing this Agreement, the Purchaser further represents that the Purchaser

Securities. The Purchaser understands that the offer and sale of the Forward Purchase Securities to the Purchaser has not been,

authorities, or an exemption from such registration and qualification requirements is available. The Purchaser acknowledges that the
Company has no obligation to register or qualify the Forward Purchase Securities for resale, except for the Registration Rights. The
Purchaser further acknowledges that if an exemption from registration or qualification is available, it may be conditioned on
various requirements including, but not limited to, the time and manner of sale, the holding period for the Forward Purchase
Securities, and on requirements relating to the Company which are outside of the Purchaser’s control, and which the Company is
under no obligation and may not be able to satisfy. The Purchaser understands that the offering of the Forward Purchase Securities
is not, and is not intended to be, part of the IPO, and that the Purchaser will not be able to rely on the protection of Section 11
of the Securities Act with respect to such Forward Purchase Securities.

law, in each case which is not withdrawn within sixty (60) days after being filed, or a receiver, fiscal agent or similar officer is appointed

In the event of any termination of this
Agreement pursuant to this Section 6, the Aggregate FPS Purchase Price (without interest thereon), if previously paid, and

shall forthwith become null and void and have no effect, without any liability on the part of the Purchaser or the Company and their
respective directors, officers, employees, partners, managers, members, or shareholders and all rights and obligations of each party
shall cease; provided, however, that nothing contained in this Section 6 shall relieve either party from
liabilities or damages arising out of any fraud or willful breach by such party of any of its representations, warranties, covenants
or agreements contained in this Agreement.

(c) Survival
of Representations and Warranties. All of the representations and warranties contained herein shall survive the FPS Closing.


 


(d) Entire
Agreement. This Agreement, together with any documents, instruments and writings that are delivered pursuant hereto or referenced
herein, constitutes the entire agreement and understanding of the parties hereto in respect of its subject matter and supersedes all prior
understandings, agreements, or representations by or among the parties hereto, written or oral, to the extent they relate in any way to
the subject matter hereof or the transactions contemplated hereby.


 


(e) Successors.
All of the terms, agreements, covenants, representations, warranties, and conditions of this Agreement are binding upon, and inure to
the benefit of and are enforceable by, the parties hereto and their respective successors. Nothing in this Agreement, express or implied,
is intended to confer upon any party other than the parties hereto or their respective successors and assigns any rights, remedies, obligations
or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement.


 


(f) Assignments.
Except as otherwise specifically provided herein, no party hereto may assign either this Agreement or any of its rights, interests, or
obligations hereunder without the prior written approval of the other parties except that the Purchaser may assign its rights or interests
hereunder to any of its advisory clients.


 


(g) Counterparts.
This Agreement may be executed in two or more counterparts, each of which will be deemed an original but all of which together will constitute
one and the same instrument.


 


(h) Headings.
The section headings contained in this Agreement are inserted for convenience only and will not affect in any way the meaning or interpretation
of this Agreement.


 


(i) Governing
Law. This Agreement, the entire relationship of the parties hereto, and any dispute between the parties (whether grounded in contract,
tort, statute, law or equity) shall be governed by, construed in accordance with, and interpreted pursuant to the laws of the State of
New York, without giving effect to its choice of laws principles.


 


(j) Jurisdiction. The
parties (i) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of New York and to the
jurisdiction of the United States District Court for the Southern District of New York for the purpose of any suit, action or other
proceeding arising out of or based upon this Agreement, (b) agree not to commence any suit, action or other proceeding arising out
of or based upon this Agreement except in state courts of New York or the United States District Court for the Southern District of
New York, and (c) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or
proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt
or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of
the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such
court.


 






    13


     


    

 


(k) Waiver
of Jury Trial. The parties hereto hereby waive any right to a jury trial in connection with any litigation pursuant to this Agreement
and the transactions contemplated hereby.


 


(l) Amendments.
This Agreement may not be amended, modified or waived as to any particular provision, except with the prior written consent of the Company
and the Purchaser.


 


(m) Severability.
The provisions of this Agreement will be deemed severable and the invalidity or unenforceability of any provision will not affect the
validity or enforceability of the other provisions hereof; provided that if any provision of this Agreement, as applied to any
party hereto or to any circumstance, is adjudged by a governmental authority, arbitrator, or mediator not to be enforceable in accordance
with its terms, the parties hereto agree that the governmental authority, arbitrator, or mediator making such determination will have
the power to modify the provision in a manner consistent with its objectives such that it is enforceable, and/or to delete specific words
or phrases, and in its reduced form, such provision will then be enforceable and will be enforced.


 


(n) Expenses.
The Company and the Purchaser will each bear their respective costs and expenses incurred in connection with the preparation, execution
and performance of this Agreement and the consummation of the transactions contemplated hereby, including all fees and expenses of their
respective agents, representatives, financial advisors, legal counsel and accountants. The Company shall be responsible for the fees of
its transfer agent; stamp taxes and all of The Depository Trust Company’s fees associated with the issuance of the Forward Purchase
Securities.


 


(o) Construction. The
parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or
interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of
proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. Any
reference to any federal, state, local, or foreign law will be deemed also to refer to law as amended and all rules and regulations
promulgated thereunder, unless the context requires otherwise. The words “include,”
“includes,” and “including” will be deemed to be followed by “without
limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words
in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words
“this Agreement,” “herein,” “hereof,” “hereby,”
“hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision
unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have
independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any
respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of
the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such
party hereto is in breach of the first representation, warranty, or covenant.


 






    14


     


    

 


(p) Waiver.
No waiver by any party hereto of any default, misrepresentation, or breach of warranty or covenant hereunder, whether intentional or not,
may be deemed to extend to any prior or subsequent default, misrepresentation, or breach of warranty or covenant hereunder or affect in
any way any rights arising because of any prior or subsequent occurrence.


 


(q) Confidentiality.
Except as may be required by law, regulation or applicable stock exchange listing requirements, unless and until the transactions contemplated
hereby and the terms hereof are publicly announced or otherwise publicly disclosed by the Company, the parties hereto shall keep confidential
and shall not publicly disclose the existence or terms of this Agreement.


 


(r) Specific
Performance. The Purchaser agrees that irreparable damage may occur in the event any provision of this Agreement was not performed
by the Purchaser in accordance with the terms hereof and that the Company shall be entitled to specific performance of the terms hereof,
in addition to any other remedy at law or equity.
