NOW, THEREFORE,
in consideration of the premises above, which are incorporated in this Agreement as if fully set forth below, and the mutual
covenants and other agreements contained in this Agreement, and for other good and valuable consideration, the receipt and
sufficiency of which is hereby acknowledged, the Company and Subscriber hereby agree as follows:


 


1.                
Subscription; Closing.


 


(a)              
Subscriber hereby applies to become a member of the Company, on the terms and conditions set forth in this Agreement and the Operating
Agreement, a copy of which has been furnished to Subscriber. Subscriber acknowledges receipt of a copy of the Operating Agreement.


 


(b)              
The Company shall admit Subscriber as a member of the Company and issue and sell to Subscriber, and Subscriber shall subscribe
for and purchase from the Company, a number of Class Y Units not to exceed the Subscribed Units for an aggregate amount not to exceed
the Aggregate Subscription Price (which shall be determined by multiplying the Subscribed Units by the Per Unit Purchase Price).


 


(c)              
The closing of the sale of the Class Y Units to Subscriber (the “Class Y Units Closing”) shall take place promptly
following the execution of this Agreement and, upon request from the Company, the delivery of the Aggregate Subscription Price in cash
via wire transfer to an account specified in writing by the Company. At the Class Y Units Closing, the Company will accept Subscriber’s
subscription for the number of Class Y Units specified on the Company’s signature page attached hereto (which number shall not exceed
the Subscribed Units) and will issue and sell to Subscriber the Class Y Units for a per Unit price equal to the Per Unit Purchase Price,
each registered in the name of Subscriber. In connection with the execution of this Agreement, Subscriber is executing and entering into
the Operating Agreement as a member of the Company.


 


(d)              
Upon execution of this Agreement, Subscriber’s obligation to subscribe for and purchase a number of Class Y Units up to the
number of Subscribed Units shall be irrevocable, and Subscriber shall be legally bound to subscribe for and purchase such Class Y Units
subject to the terms set forth in this Agreement.


 


(e)              
Subscriber understands and agrees that the Company reserves the right to reject this subscription for Class Y Units in whole or
part in any order at any time prior to the closing of the sale of the Class Y Units Closing for any or no reason, notwithstanding Subscriber’s
prior receipt of notice of acceptance of Subscriber’s subscription.


 


(f)               
In the event of rejection of this subscription by the Company in accordance with Section 1(e), or the sale of the Class
Y Units is not consummated for any reason, this Agreement and any other agreement entered into between Subscriber and the Company relating
to this subscription shall thereafter have no force or effect, and the Company shall promptly return or cause to be returned to Subscriber
any portion of the Aggregate Subscription Price remitted to the Company, without interest thereon or deduction therefrom. If the Aggregate
Subscription Price is returned in full because the Company rejects Subscriber’s entire subscription, this Agreement and Subscriber’s
admission as a member to the Company shall be null and void ab initio.


 






    3


     


    

 


(g)               Subscriber
has indicated its intention to purchase in the IPO a number of Units of TradeUP that are sold to the public in the IPO equal to 9.9%
of the number of such Units sold in the IPO (the “Purchased Public Units Amount”). In conjunction with such
purchase of Interests, the Operating Agreement will reflect the allocation to Subscriber of an indirect ownership interest in 50,000
shares of common stock of Trade (“Founder Shares”) held by the Company through the purchase of the Subscribed
Units. Notwithstanding the foregoing, in the event Subscriber purchases less
than the Purchased Public Units Amount solely due to the fact that the number of Units sold in the IPO is reduced and/or the underwriter
of the IPO allocates less Units to the Subscriber than the Purchased Public Units Amount (the “Alternate Subscriber Purchase
Amount”) then, if the Subscriber purchases the Alternate Subscriber Purchase Amount (i) the Subscriber shall still be entitled
to purchase (A) the Interests and (B) the allocation of Founder Shares and (ii) the balance of the Aggregate Purchase Price less the amount
of the Alternate Subscriber Purchase Amount shall be returned to the Subscriber. The schedule of members attached to the Operating
Agreement shall be amended at that time to reflect any such reduced allocation of Subscribed Units/Founder Shares to Subscriber.


 


2.                
Representations and Warranties of Subscriber. Subscriber
represents and warrants to the Company as follows:


 


(a)

to carry on its business as presently conducted and as proposed to be conducted.


 


(b)              
Subscriber has full power and authority to enter into this Agreement. This Agreement, when executed and delivered by Subscriber,

relief or other equitable remedies.

state or local governmental authority is required on the part of Subscriber in connection with the consummation of the transactions contemplated
by this Agreement.


 


(d)              
The execution, delivery and performance by Subscriber of this Agreement and the consummation by Subscriber of the transactions

Agreement is made with Subscriber in reliance upon Subscriber’s representation to the Company, which by Subscriber’s

investment for Subscriber’s own account, not as a nominee or agent, and not with a view to the resale or distribution of any
part thereof, and that Subscriber has no present intention of selling, granting any participation in, or otherwise distributing the
same in violation of law. By executing this Agreement, Subscriber further represents that Subscriber does not presently have any
contract, undertaking, agreement or arrangement with any person to sell, transfer or grant participations to such person or to any
third person, with respect to any of the Class Y Units. If Subscriber was formed for the specific purpose of acquiring the Class Y
Units, each of its equity owners is an accredited investor as defined in Rule 501(a) of Regulation D promulgated under the
Securities Act.


 


(f)               
Subscriber has had an opportunity to discuss the Company’s and TradeUP’s business, management, financial affairs and

(g)

qualified by state authorities, or an exemption from such registration and qualification requirements is available. Subscriber acknowledges
that the Company has no obligation to register or qualify the Class Y Units for resale. Subscriber 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 Class Y Units, and on requirements relating to the Company which are outside of Subscriber’s
control, and which the Company is under no obligation and may not be able to satisfy. Subscriber acknowledges that TradeUP filed the Registration
Statement for its proposed IPO to the SEC for review. Subscriber understands that the offering of the Class Y Units is not, and is not
intended to be, part of the IPO, and that Subscriber will not be able to rely on the protection of Section 11 of the Securities Act with
respect to such Class Y Units.


 


(h)              
Subscriber understands that no public market now exists for the Class Y Units or the securities of TradeUP underlying the Class
Y Units, and that the Company has made no assurances that a public market will ever exist for the Class Y Units or the securities of TradeUP
underlying the Class Y Units.


 


(i)

(x)               Subscriber
represents and warrants that it is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked
Persons administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any
Executive Order issued by the President of the United States and administered by OFAC (“OFAC List”), or a person
or entity prohibited by any sanctions program by OFAC, the United Nations Security Council, the European Union, Her Majesty’s
Treasury of the United Kingdom, or other relevant sanctions authority (collectively, “Sanctions”), (ii) a
Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515, or (iii) a non-U.S. shell bank or
providing banking services indirectly to a non-U.S. shell bank. Subscriber agrees to provide law enforcement agencies, if requested
thereby, such records as required by applicable law, provided that Subscriber is permitted to do so under applicable law. Subscriber

the USA PATRIOT Act of 2001 and its implementing regulations (collectively, the “BSA/PATRIOT Act”), Subscriber
maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT Act. Subscriber

investors against Sanctions, including the OFAC List. Subscriber further represents and warrants that, to the extent required, it

Subscribed Shares were legally derived.


 


(y)              
Subscriber acknowledges that the Company has or will enter into the Letter Agreement with TradeUP pursuant to which it has agreed
to waive its redemption rights with respect to any Founder Shares it holds in TradeUP. In the event that the IPO is completed and TradeUP
does not complete a business combination within 18 months following the IPO, the Company will be unable to redeem its Founder Shares in
TradeUP and the Class Y Units will, in such circumstances, be worthless.


 


(z)              
Subscriber acknowledges that the Class Y Units only represent Founder Shares and the Subscriber is not entitled to redeem or exchange
the securities at the Subscriber's option for other securities of TradeUP held by the Company.

share splits, subdivisions, reorganisations or similar changes in the capital structure of TradeUP or as a result of or in connection
with a Business Combination. In the event of such adjustments, each Class Y Unit could represent less than one or more than one Founder
Share depending on the relevant adjustment. Where any adjustment of the Founder Shares is made, the adjustment will be shared pro rata
between the holders of Class Y Units. This may lead to the Subscriber holding fractional Class Y Units or Founder Shares or entitled to
fractional securities in TradeUP. As TradeUP will not issue fractional securities, the Company will round down any fractions to the nearest
whole number and Subscriber will, and hereby irrevocably agrees to, forfeit those fractions. Any fractional Class Y Units or Founder Shares
so forfeited will be the property of the Company.


 


(bb)          
Subscriber acknowledges to the Company that (i) the Company may require further verification of the identity and source of Subscriber's
funds and/or wealth before the application can be processed and (ii) if the verification evidence supplied is not satisfactory, the Company
may, at the Subscriber's expense, return the subscription funds tendered, without interest, to the bank account from which they were remitted.
Subscriber hereby releases the Company from all claims for any loss that it may suffer as a result of that action, and it hereby waives
all such claims.

of general application relating to or affecting the enforcement of creditors’ rights generally, or (ii) as limited by laws relating

5.                 
Subscriber Rights, Waivers and Covenants.


 


(a)              
 Subscriber shall not be entitled to any registration rights with respect to Class Y Units other than the IPO Registration Rights
(or rights set forth in any other agreement entered into in connection with the Business Combination that supersedes such IPO Registration
Rights, which, Subscriber acknowledges and agrees may vary from the IPO Registration Rights (including in a manner that is adverse to
the Company or Subscriber)) as a transferee of the Founder Shares owned by the Company. In addition, should Subscriber receive a distribution
of any securities of TradeUP or any successor entity resulting from the Business Combination whose securities are publicly traded (“Pubco”)
held by the Company, Subscriber will be asked to execute a letter agreement with TradeUP or Pubco in substantially the same form as that
certain Letter Agreement to be entered into between the Company and TradeUP in connection with the IPO which will be filed with the SEC
as an exhibit to the Registration Statement (the "Letter Agreement") (or any amendment to such Letter Agreement or subsequent
agreement entered into, including in connection with the Business Combination Agreement that supplements, replaces or supersedes such
Letter Agreement), if such distribution were to occur prior to the expiration of any applicable lock-up periods contained therein.


 


(b)               Subscriber
hereby acknowledges that TradeUP will establish a trust account (the “Trust Account”) containing the proceeds of
the IPO and from certain private placements occurring simultaneously with the IPO (including interest accrued from time to time
thereon) for the benefit of TradeUP’s public stockholders (the “Public Stockholders”) and certain other
parties (including the underwriters of the IPO). Subscriber hereby agrees (on its own behalf and on behalf of its affiliates and
representatives) that Subscriber does not now or shall at any time hereafter have any right, title, interest or claim of any kind in
or to any monies in the Trust Account or distributions therefrom, or make any claim against the Trust Account (including any
distributions therefrom) arising as a result of, in connection with or relating in any way to, this Agreement or a potential
Business Combination, and regardless of whether such claim arises based on contract, tort, equity or any other theory of legal
liability (collectively, the “Released Claims”). Subscriber, on behalf of itself and its affiliates and
representatives hereby irrevocably waives any Released Claims that Subscriber or any of its affiliates and representatives may have
against the Trust Account (including any distributions therefrom) now or in the future as a result of, or arising out of, this
Agreement or a potential Business Combination and will not seek recourse against the Trust Account (including any distributions
therefrom) for any reason whatsoever (including for an alleged breach of this Agreement or any other agreement entered into
regarding a potential Business Combination). Subscriber agrees and acknowledges that such irrevocable waiver is material to this
Agreement and specifically relied upon by the Company to induce the Company to enter into this Agreement, and Subscriber further
intends and understands such waiver to be valid, binding and enforceable against Subscriber and each of its affiliates and
representatives under applicable law.  To the extent Subscriber and any of its affiliates and representatives commence any
action or proceeding based upon, in connection with, relating to or arising out of this Agreement or a potential Business
Combination, which proceeding seeks, in whole or in part, monetary relief against TradeUP or its representatives, Subscriber hereby
acknowledges and agrees that its and its affiliates’ and representatives’ sole remedy shall be against funds held
outside of the Trust Account and that such claim shall not permit Subscriber or its affiliates and representatives (or any person
claiming on the behalf or in lieu of Subscriber or its affiliates and representatives) to have any claim against the Trust Account
(including any distributions therefrom) or any amounts contained therein.  In the event Subscriber or any of its affiliates or
representatives commences any action or proceeding based upon, in connection with, relating to or arising out of this Agreement or a
potential Business Combination, which proceeding seeks, in whole or in part, relief against the Trust Account (including any
distributions therefrom) or the Public Stockholders, whether in the form of money damages or injunctive relief, TradeUP and its
representatives, as applicable, shall be entitled to recover from Subscriber and its affiliates and representatives the associated
legal fees and costs in connection with any such action, in the event TradeUP or its representatives, as applicable, prevails in
such action or proceeding.
