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	 



    CONFIDENTIAL


    

 


		(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 without
the exercise of the over-allotment option by the underwriters (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 40,000 shares of common stock of TradeUP (“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 (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.



 


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



 


		(a)	If an entity, Subscriber is duly organized, validly existing,
and in good standing under the laws of the jurisdiction of its formation (if the concept of “good standing” is a recognized
concept in such jurisdiction) and has all requisite power and authority 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, will constitute the valid and legally binding obligation of Subscriber,
enforceable in accordance with its terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
conveyance and any other laws of general application affecting enforcement of creditors’ rights generally, or (b) as limited by
laws relating to the availability of specific performance, injunctive relief or other equitable remedies.



 


		(c)	No consent, approval, order or authorization of, or registration,
qualification, designation, declaration or filing with, any federal, 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 contemplated by this Agreement will not result in any violation
or default (i) of any provisions of its organizational documents, if applicable, (ii) of any instrument, judgment, order, writ or decree
to which it is a party or by which it is bound, (iii) under any note, 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 it is a party or by which it is bound or (v) of any provision
of federal or state statute, rule or regulation applicable to Subscriber, in each case (other than clause (i)), which would have a material
adverse effect on Subscriber or its ability to consummate the transactions contemplated by this Agreement.



 






    	 	4	 



    CONFIDENTIAL


    

 


		(e)	This Agreement is made with Subscriber in reliance upon Subscriber’s
representation to the Company, which by Subscriber’s execution of this Agreement, Subscriber hereby confirms, that the Class Y
Units to be acquired by Subscriber will be acquired for 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 the terms and conditions of the offering of the Class Y Units and the
Operating Agreement, as well as the terms and conditions of the IPO and the Founder Shares, with the Company’s and TradeUP’s
management. Subscriber has reviewed the Registration Statement and understands the terms and conditions of the Founder Shares.



 


		(g)	Subscriber understands that the offer and sale of the Class
Y Units to Subscriber has not been, and will not be, registered under the Securities Act, by reason of a specific exemption from the

the accuracy of Subscriber’s representations as expressed herein. Subscriber understands that the Class Y Units are “restricted
securities” under applicable U.S. federal and state securities laws and that, pursuant to these laws, Subscriber must hold the
Class Y Units indefinitely unless they are registered with the SEC and 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)	Subscriber understands that its agreement to purchase the
Class Y Units involves a high degree of risk which could cause Subscriber to lose all or part of its investment, and that the Company
will vote the Founder Shares in favor of the Business Combination.



 


		(j)	Subscriber is an “accredited investor” as defined
by Rule 501(a) of Regulation D promulgated under the Securities Act, as set forth on the Questionnaire attached hereto, which is incorporated
by reference herein, and has such knowledge and experience in financial and business matters that Subscriber is capable of evaluating
the merits and risks of Subscriber’s investment in the Class Y Units, of making an informed investment decision with respect thereto,
and has the ability and capacity to protect Subscriber’s interests. The Subscriber is not subject to the “Bad Actor”
disqualification, as such terms is defined in Rule 506 of Regulation D, promulgated under the Securities Act.

jurisdiction in connection with any invitation to subscribe for the Class Y Units or any use of this Agreement, including (i) the legal
requirements within its jurisdiction for the purchase of the Class Y Units, (ii) any foreign exchange restrictions applicable to such
purchase, (iii) any governmental or other consents that may need to be obtained, and (iv) the income tax and other tax consequences,
if any, that may be relevant to the purchase, holding, redemption, sale, or transfer of the Class Y Units. Subscriber’s subscription
and payment for and continued beneficial ownership of the Class Y Units will not violate any applicable securities or other laws of Subscriber’s
jurisdiction.



 


		(l)	Neither Subscriber, nor any of its officers, directors, employees,
agents, stockholders or partners has either directly or indirectly, including, through a broker or finder (i) to its knowledge, engaged
in any general solicitation, or (ii) published any advertisement in connection with the offer and sale of the Class Y Units.



 


		(m)	If Subscriber is an individual, then Subscriber resides in
the state or province identified in the address of Subscriber set forth on the signature page hereof; if Subscriber is a partnership,
corporation, limited liability company or other entity, then its principal place of business is the office or offices located at the
address or addresses of Subscriber set forth on the signature page hereof.



 


		(n)	Subscriber acknowledges its obligations under applicable
securities laws with respect to the treatment of non-public information relating to TradeUP and the Company.

		(s)	Any sales, transfers, or other dispositions of the Class
Y Units by Subscriber, if any, will be made in compliance with the Securities Act and all applicable rules and regulations promulgated
thereunder.



 


		(t)	Subscriber represents that (i) Subscriber has (and could
be reasonably assumed to have) the ability and capacity to protect his, her or its interests in connection with this subscription; or

		(u)	Subscriber represents and warrants, to the best of Subscriber’s
knowledge, that no finder, broker, agent, financial advisor or other intermediary, nor any purchaser representative or any broker-dealer
acting as a broker, is entitled to any compensation in connection with the transactions contemplated by this Subscription Agreement.



 


		(v)	Except for the specific representations and warranties expressly
made by the Company in Section 3 of this Agreement, Subscriber specifically disclaims that he, she or it is relying upon any other
representations or warranties that may have been made by the Company, any person on behalf of the Company or any of the Company’s
affiliates.



 


		(w)	Subscriber acknowledges that, pursuant to the Operating Agreement,
prior to, or at the time of, the Business Combination, in order to facilitate such a Business Combination, the Manager (as defined in
the Operating Agreement) has the authority to cause the Company to surrender or forfeit, transfer or exchange or otherwise dispose of

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. Notwithstanding the foregoing, nothing shall prevent the Subscriber from redeeming any Common Stock it has purchased
pursuant to the Registration Statement.
