RE:        Securities Subscription Agreement

 

Gentlemen:

 

This agreement
(this “Agreement”) is entered into on December 15, 2020 by and between Tailwind International Sponsor LLC,
a Cayman Islands exempted limited liability company (the “Subscriber” or “you”), and
Tailwind International Acquisition Corp., a Cayman Islands exempted company (the “Company”). Pursuant to
the terms hereof, the Company hereby accepts the offer the Subscriber has made to purchase 7,187,500 Class B ordinary shares,
$0.0001 par value per share (the “Shares”), up to 937,500 of which are subject to surrender and
cancellation by you if the underwriters of the initial public offering (“IPO”) of units
(“Units”) of the Company do not fully exercise their over-allotment option (the “Over-allotment
Option”). The Company and the Subscriber’s agreements regarding such Shares are as follows:

 

		1.	Purchase of Securities.

 

		1.1	Purchase of Shares. For the sum of $25,000 (the “Purchase Price”), which
the Company acknowledges receiving in cash, the Company hereby issues the Shares to the Subscriber, and the Subscriber hereby subscribes
for and purchases the Shares from the Company, 937,500 of which are subject to surrender and cancellation, on the terms and subject
to the conditions set forth in this Agreement. All references in this Agreement to shares of the Company being surrendered and
canceled shall take effect as surrenders and cancellations for no consideration of such shares as a matter of Cayman Islands law.

 

		1.2	Surrender of Subscriber Shares. On the issuance of the Shares, the Subscriber hereby surrenders
for no consideration the one Class B ordinary share, $0.0001 par value, that the Subscriber holds in the Company.

 

		2.	Representations, Warranties and Agreements.

 

		2.1	Subscriber’s Representations, Warranties and Agreements. To induce the Company to
issue the Shares to the Subscriber, the Subscriber hereby represents and warrants to the Company and agrees with the Company as
follows:

 

		2.1.1	No Government Recommendation or Approval. The Subscriber understands that no federal or
state agency has passed upon or made any recommendation or endorsement of the offering of the Shares.

 

     

     

    

 

		2.1.2	No Conflicts. The execution, delivery and performance of this Agreement and the consummation
by the Subscriber of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) the formation
and governing documents of the Subscriber, (ii) any agreement, indenture or instrument to which the Subscriber is a party or (iii)
any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order, judgment or decree to which the
Subscriber is subject.

 

		2.1.3	Registration and Authority. The Subscriber is a Cayman Islands exempted limited liability
company, validly existing and in good standing under the laws of the Cayman Islands and possesses all requisite power and authority
necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by you, this Agreement will
be a legal, valid and binding agreement of Subscriber, enforceable against Subscriber in accordance with its terms, except as such
enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar laws affecting the enforcement
of creditors’ rights generally and subject to general principles of equity (regardless of whether enforcement is sought in
a proceeding at law or in equity).

 

		2.1.4	Experience, Financial Capability and Suitability. Subscriber is: (i) sophisticated in financial
matters and is able to evaluate the risks and benefits of the investment in the Shares and (ii) able to bear the economic risk
of its investment in the Shares for an indefinite period of time because the Shares have not been registered under the Securities
Act (as defined below) and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from
such registration is available. Subscriber is capable of evaluating the merits and risks of its investment in the Company and has
the capacity to protect its own interests. Subscriber must bear the economic risk of this investment until the Shares are sold
pursuant to: (i) an effective registration statement under the Securities Act or (ii) an exemption from registration available
with respect to such sale. Subscriber is able to bear the economic risks of an investment in the Shares and to afford a complete
loss of Subscriber’s investment in the Shares.

 

		2.1.5	Access to Information; Independent Investigation. Prior to the execution of this Agreement,
the Subscriber has had the opportunity to ask questions of and receive answers from representatives of the Company concerning an
investment in the Company, as well as the finances, operations, business and prospects of the Company, and the opportunity to obtain
additional information to verify the accuracy of all information so obtained. In determining whether to make this investment, Subscriber
has relied solely on Subscriber’s own knowledge and understanding of the Company and its business based upon Subscriber’s
own due diligence investigation and the information furnished pursuant to this paragraph. Subscriber understands that no person
has been authorized to give any information or to make any representations
which were not furnished pursuant to this Section 2 and Subscriber has not relied on any other representations or information in
making its investment decision, whether written or oral, relating to the Company, its operations and/or its prospects.

 

    2 

     

    

 

		2.1.6	Regulation D Offering. Subscriber represents that it is an “accredited investor”
as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”)
and acknowledges the sale contemplated hereby is being made in reliance on a private placement exemption to “accredited investors”
within the meaning of Section 501(a) of Regulation D under the Securities Act or similar exemptions under federal and state law.

 

		2.1.7	Investment Purposes. The Subscriber is purchasing the Shares solely for investment purposes,
for the Subscriber’s own account and not for the account or benefit of any other person, and not with a view towards the
distribution or dissemination thereof. The Subscriber did not decide to enter into this Agreement as a result of any general solicitation
or general advertising within the meaning of Rule 502 of Regulation D under the Securities Act.

 

		2.1.8	Restrictions on Transfer; Shell Company. Subscriber understands the Shares are being offered
in a transaction not involving a public offering within the meaning of the Securities Act. Subscriber understands the Shares will
be “restricted securities” within the meaning of Rule 144(a)(3) under the Securities Act, and Subscriber understands
that the certificates representing the Shares will contain a legend in respect of such restrictions. If in the future the Subscriber
decides to offer, resell, pledge or otherwise transfer the Shares, such Shares may be offered, resold, pledged or otherwise transferred
only pursuant to: (i) registration under the Securities Act, or (ii) an available exemption from registration. Subscriber agrees
that if any transfer of its Shares or any interest therein is proposed to be made, as a condition precedent to any such transfer,
Subscriber may be required to deliver to the Company an opinion of counsel satisfactory to the Company. Absent registration or
an exemption, the Subscriber agrees not to resell the Shares. Subscriber further acknowledges that because the Company is a shell
company, Rule 144 may not be available to the Subscriber for the resale of the Shares until one year following consummation of
the initial business combination of the Company, despite technical compliance with the requirements of Rule 144 and the release
or waiver of any contractual transfer restrictions.

 

		2.1.9	No Governmental Consents. No governmental, administrative or other third party consents
or approvals are required or necessary on the part of Subscriber in connection with the transactions contemplated by this Agreement.

 

    3 

     

    

 

2.2       Company’s
Representations, Warranties and Agreements. To induce the Subscriber to purchase the Shares, the Company hereby represents
and warrants to the Subscriber and agrees with the Subscriber as follows:

 

		2.2.1	Incorporation and Corporate Power. The Company is a Cayman Islands exempted company and
is qualified to do business in every jurisdiction in which the failure to so qualify would reasonably be expected to have a material
adverse effect on the financial condition, operating results or assets of the Company. The Company possesses all requisite corporate
power and authority necessary to carry out the transactions contemplated by this Agreement. Upon execution and delivery by the
Company, this Agreement will be a legal, valid and binding agreement of the Company, enforceable against the Company in accordance
with its terms, except as such enforceability may be limited by applicable bankruptcy, insolvency, fraudulent conveyance or similar
laws affecting the enforcement of creditors’ rights generally and subject to general principles of equity (regardless of
whether enforcement is sought in a proceeding at law or in equity).

 

	 	2.2.2	No Conflicts. The execution, delivery and performance of this Agreement and the
                                                                 consummation by the Company of the transactions contemplated hereby do not violate, conflict with or constitute a default
                                                                 under (i) the memorandum and articles of association of the Company, (ii) any agreement, indenture or instrument to which the
                                                                 Company is a party or (iii)  
any law, statute, rule or regulation to which the Company is subject, or any agreement, order, judgment or decree to which the
Company is subject.

 

		2.2.3	Title to Securities. Upon issuance in accordance with, and payment pursuant to, the terms
hereof, and registration in the Company’s register of members, the Shares will be duly and validly issued, fully paid and
nonassessable. Upon issuance in accordance with, and payment pursuant to, the terms hereof, and registration in the Company’s
register of members, the Subscriber will have or receive good title to the Shares, free and clear of all liens, claims and encumbrances
of any kind, other than (a) transfer restrictions hereunder and other agreements to which the Shares may be subject, (b) transfer
restrictions under federal and state securities laws, and (c) liens, claims or encumbrances imposed due to the actions of the Subscriber.

 

		2.2.4	No Adverse Actions. There are no actions, suits, investigations or proceedings pending, threatened against or affecting the Company which: (i)   
seek to restrain, enjoin, prevent the consummation of or otherwise affect the transactions contemplated by this Agreement or (ii)
question the validity or legality of any transactions or seeks to recover damages or to obtain other relief in connection with
any transactions.

 

    4 

     

    

 

		3.	Surrender and Cancellation of Shares.

 

		3.1	Partial or No Exercise of the Over-allotment Option. In the event the Over-allotment Option
granted to the representative(s) of the underwriters of the Company’s IPO is not exercised in full, the Subscriber acknowledges
and agrees that it shall surrender for cancellation any and all rights to such number of Shares (up to an aggregate of 937,500
Shares and pro rata based upon the percentage of the Over-allotment Option exercised) such that immediately following such surrender,
the Subscriber (and all other initial shareholders prior to the IPO, if any) will own an aggregate number of Shares (not including
ordinary shares issuable upon exercise of any warrants or any ordinary shares purchased by Subscriber in the Company’s IPO
or in the aftermarket) equal to 20% of the issued and outstanding ordinary shares of the Company immediately following the IPO.

 

		3.2	Termination of Rights as Shareholder. If any of the Shares are surrendered and cancelled
in accordance with this Section 3, then after such time the Subscriber (or successor in interest), shall no longer have any rights
as a holder of such Shares, and the Company shall take such action as is appropriate to cancel such Shares.

 

		4.	Waiver of Liquidation Distributions; Redemption Rights. In connection with the Shares purchased
pursuant to this Agreement, the Subscriber hereby waives any and all right, title, interest or claim of any kind in or to any distributions
by the Company from the trust account which will be established for the benefit of the Company’s public shareholders and
into which substantially all of the proceeds of the IPO will be deposited (the “Trust Account”), in the event
of a liquidation of the Company upon the Company’s failure to timely complete an initial business combination. For purposes
of clarity, in the event the Subscriber purchases ordinary shares in the IPO or in the aftermarket, any additional Shares so purchased
shall be eligible to receive any liquidating distributions by the Company. However, in no event will the Subscriber have the right
to redeem any ordinary shares into funds held in the Trust Account upon the successful completion of an initial business combination.

 

		5.	Restrictions on Transfer.

 

		5.1	Securities Law Restrictions. In addition to any restrictions to be contained in that
                                                               certain letter agreement (commonly known as an “Insider Letter”) to be dated as of the closing of the IPO
                                                               by and between Subscriber and the Company, Subscriber agrees not to sell, transfer, pledge, hypothecate or otherwise dispose
                                                               of all or any part of the Shares unless, prior thereto (a) a registration statement on the appropriate form under the
                                                               Securities Act and applicable state securities laws with respect to the Shares proposed to be transferred shall then be
                                                               effective or (b) the Company has received an opinion from counsel reasonably satisfactory to the Company, that such
                                                               registration is not required because such transaction is exempt from registration under the Securities Act and the rules
                                                               promulgated by the Securities and Exchange Commission thereunder and with all applicable state securities laws.

 

    5 

     

    

 

		5.2	Restrictive Legends. Any certificates representing the Shares shall have endorsed thereon
legends substantially as follows:

 

“THE SECURITIES REPRESENTED HEREBY
HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND NEITHER THE
SECURITIES NOR ANY INTEREST THEREIN MAY BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN EFFECTIVE
REGISTRATION STATEMENT UNDER SUCH ACT OR SUCH LAWS OR AN EXEMPTION FROM REGISTRATION UNDER SUCH ACT AND SUCH LAWS WHICH, IN THE
OPINION OF COUNSEL, IS AVAILABLE.”

 

“THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO LOCKUP PROVISIONS AND MAY NOT BE OFFERED, SOLD, TRANSFERRED, PLEDGED OR OTHERWISE DISPOSED DURING THE
TERM OF THE LOCKUP.”

 

		5.3	Additional Shares or Substituted Securities. In the event of the declaration of a share
capitalization, the declaration of an extraordinary dividend payable in a form other than Shares, a spin-off, a share sub-division,
an adjustment in conversion ratio, a recapitalization or a similar transaction affecting the Company’s outstanding Shares
without receipt of consideration, any new, substituted or additional securities or other property which are by reason of such transaction
distributed with respect to any Shares subject to this Section 5 or into which such Shares thereby become convertible shall immediately
be subject to this Section 5 and Section 3. Appropriate adjustments to reflect the distribution of such securities or property
shall be made to the number and/or class of Shares subject to this Section 5 and Section 3.

 

		5.4	Registration Rights. Subscriber acknowledges that the Shares are being purchased pursuant
to an exemption from the registration requirements of the Securities Act and will become freely tradable only after certain conditions
are met or they are registered pursuant to a Registration and Shareholder Rights Agreement to be entered into with the Company
prior to the closing of the IPO.

party hereto. Nothing in this Agreement shall be construed to create any rights or obligations except among the parties hereto,
and no person or entity shall be regarded as a third-party beneficiary of this Agreement.

 

		6.8	Governing Law. This Agreement and the rights and obligations of the parties hereunder shall
be construed in accordance with and governed by the laws of New York applicable to contracts wholly performed within the borders
of such state, without giving effect to the conflict of law principles thereof.

		6.9	Severability. In the event that any court of competent jurisdiction shall determine that
any provision, or any portion thereof, contained in this Agreement shall be unreasonable or unenforceable in any respect, then
such provision shall be deemed limited to the extent that such court deems it reasonable and enforceable, and as so limited shall
remain in full force and effect. In the event that such court shall deem any such provision, or portion thereof, wholly unenforceable,
the remaining provisions of this Agreement shall nevertheless remain in full force and effect.

 

		6.10	No Waiver of Rights, Powers and Remedies. No failure or delay by a party hereto in exercising
any right, power or remedy under this Agreement, and no course of dealing between the parties hereto, shall operate as a waiver
of any such right, power or remedy of such party. No single or partial exercise of any right, power or remedy under this Agreement
by a party hereto, nor any abandonment or discontinuance of steps to enforce any such right, power or remedy, shall preclude such
party from any other or further exercise thereof or the exercise of any other right, power or remedy hereunder. The election of
any remedy by a party hereto shall not constitute a waiver of the right of such party to pursue other available remedies. No notice
to or demand on a party not expressly required under this Agreement shall entitle the party receiving such notice or demand to
any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of the party giving
such notice or demand to any other or further action in any circumstances without such notice or demand.

 

		6.11	Survival of Representations and Warranties. All representations and warranties made by the
parties hereto in this Agreement or in any other agreement, certificate or instrument provided for or contemplated hereby, shall
survive the execution and delivery hereof and any investigations made by or on behalf of the parties.

 

		6.12	No Broker or Finder. Each of the parties hereto represents and warrants to the other that
no broker, finder or other financial consultant has acted on its behalf in connection with this Agreement or the transactions contemplated
hereby in such a way as to create any liability on the other. Each of the parties hereto agrees to indemnify and save the other
harmless from any claim or demand for commission or other compensation by any broker, finder, financial consultant or similar agent
claiming to have been employed by or on behalf of such party and to bear the cost of legal expenses incurred in defending against
any such claim.

 

		6.13	Headings and Captions. The headings and captions of the various subdivisions of this Agreement
are for convenience of reference only and shall in no way modify or affect the meaning or construction of any of the terms or provisions
hereof.

 

		6.14	Counterparts. This Agreement
                                         may be executed in one or more counterparts, all of which when taken together shall be
                                         considered one and the same agreement and shall become effective when counterparts have
                                         been signed by each party and delivered to the other party, it being understood that
                                         both parties need not sign the same counterpart. In the event that any signature is delivered
                                         by facsimile transmission or any other form
of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such
signature is executed) with the same force and effect as if such signature page were an original thereof.

		6.15	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. 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.

 

		6.16	Mutual Drafting. This Agreement is the joint product of the Subscriber and the Company and
each provision hereof has been subject to the mutual consultation, negotiation and agreement of such parties and shall not be construed
for or against any party hereto.

 

		7.	Voting and Redemption of Shares. Subscriber agrees to vote the Shares in favor of an initial
business combination that the Company negotiates and submits for approval to the Company’s shareholders and shall not seek
redemption or repurchase with respect to such Shares. Additionally, the Subscriber agrees not to tender any Shares in connection
with a tender offer presented to the Company’s shareholders in connection with an initial business combination negotiated
by the Company.
