Re:  Initial Public Offering



Ladies and Gentlemen:


 


This letter (this “Letter Agreement”) is being delivered
to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”) to be entered into by and among TradeUP
Acquisition Corp., a Delaware corporation (the “Company”), US Tiger Securities, Inc., Kingswood Capital Markets, division
of Benchmark Investments, LLC and R.F. Lafferty & Co., Inc., as the representatives of the underwriters (each, an “Underwriter”
and collectively, the “Underwriters”), relating to an underwritten initial public offering (the “Public Offering”),
of up to 4,000,000 of the Company’s units (including up to 600,000 units that may be purchased to cover over-allotments, if any)
(the “Units”), each comprised of one share of the Company’s common stock, par value $0.0001 per share (the “Common
Stock”), and one-half of one redeemable warrant. Each Warrant (each, a “Warrant”) entitles the holder thereof to purchase
one share of Common Stock at a price of $11.50 per share, subject to adjustment. No fractional warrants will be issued upon separation
of the units and only whole warrants will trade. Accordingly, unless you purchase at least two units, you will not be able to receive
or trade a whole warrant. The Units shall be sold in the Public Offering pursuant to a registration statement on Form S-1 and prospectus
(the “Prospectus”) filed by the Company with the Securities and Exchange Commission (the “Commission”) and the
Units have been approved to be listed on the Nasdaq Capital Market. Certain capitalized terms used herein are defined in paragraph 11
hereof.


 


In order to induce the Company
and the Underwriters to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, TradeUP Acquisition Sponsor LLC (the “Sponsor”),
Tradeup INC. (together with the Sponsor, the “Founders”), and each of the undersigned individuals, each of whom is a member
of the Company’s board of directors and/or management team (each, an “Insider” and collectively, the “Insiders”),
hereby agrees with the Company as follows:


 


1.                 
The Founders and each Insider agree that if the Company seeks stockholder approval of a proposed Business Combination, then in
connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Common Stock owned by it, him or her in
favor of any proposed Business Combination and (ii) not redeem any shares of Common Stock owned by it, him or her in connection with such
stockholder approval. If the Company engages in a tender offer in connection with any proposed Business Combination, each Insider agrees
that it, he or she will not seek to sell its, his or her shares of Common Stock to the Company in connection with such tender offer.


 


2.                  The
Founders and each Insider hereby agrees that in the event that the Company fails to consummate a Business Combination within 18
months from the closing of the Public Offering or such later period approved by the Company’s stockholders in accordance with
the Company’s amended and restated certificate of incorporation, the Founders and each Insider shall take all reasonable steps
to cause the Company to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but
not more than 10 business days thereafter, subject to lawfully available funds therefor, redeem 100% of the Common Stock sold as
part of the Units in the Public Offering (the “Offering Shares”), at a per-share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not
previously released to the Company to pay its taxes (less up to $50,000 of interest to pay dissolution expenses), divided by the
number of then outstanding Offering Shares, which redemption will completely extinguish all Public Stockholders’ rights as
stockholders of the Company (including the right to receive further liquidation distributions, if any), subject to applicable law,
and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining
stockholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s
obligations under Delaware law to provide for claims of creditors and other requirements of applicable law. The Founders and each
Insider agree not to propose any amendment to the Company’s amended and restated certificate of incorporation that would
modify (i) the substance or timing of the Company’s obligation to allow redemption in connection with our initial business
combination or to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within 18 months from
the closing of the Public Offering or (ii) the other material provisions relating to stockholders’ rights or pre-initial
business combination activities, unless the Company provides its Public Stockholders with the opportunity to redeem their Offering
Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in
the Trust Account, including interest (which interest shall be net of amounts released for payment of taxes and amounts released to
us for working capital purposes) divided by the number of then outstanding Offering Shares. The Founders and each Insider agree to
waive its redemption rights with respect to shares of Common Stock owned by it in connection with a stockholder vote to approve an
amendment to the Company’s amended and restated certificate of incorporation (A) to modify the substance or timing of the
Company’s obligation allow redemption in connection with our initial business combination or to redeem 100% of the Offering
Shares if the Company does not complete a Business Combination within 18 months from the closing of the Public Offering or (B) with
respect to any other provision relating to stockholders’ rights or pre-initial business combination activity.

3.                 
Each of the Founders and each Insider acknowledges that it, he or she has no right, title, interest or claim of any kind in or
to any monies held in the Trust Account or any other asset of the Company as a result of any liquidation of the Company with respect to
the Founder Shares held by it, him or her. The Founders and each Insider hereby further waives, with respect to any shares of Common Stock
held by it, him or her, if any, any redemption rights it, he or she may have in connection with the consummation of a Business Combination,
including, without limitation, any such rights available in the context of a stockholder vote to approve such Business Combination or
in the context of a tender offer made by the Company to purchase shares of Common Stock (although the Founders, the Insiders and their
respective affiliates shall be entitled to redemption and liquidation rights with respect to any Offering Shares it or they hold if the
Company fails to consummate a Business Combination within 18 months from the closing of the Public Offering.


 


4.                  In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any other
shareholders, members or managers of the Sponsor) agrees to indemnify and hold harmless the Company against any and all loss,
liability, claim, damage and expense whatsoever (including, but not limited to, any and all legal or other expenses reasonably
incurred in investigating, preparing or defending against any litigation, whether pending or threatened, or any claim whatsoever) to
which the Company may become subject as a result of any claim by (i) any third party (other than the Company’s independent
accountants) for services rendered or products sold to the Company or (ii) a prospective target business with which the Company has
entered into a letter of intent, confidentiality or other similar agreement for a Business Combination agreement (a
 “Target”); provided, however, that such indemnification of the Company by the Sponsor shall apply only to the extent
necessary to ensure that such claims by a third party for services rendered (other than the Company’s independent public
accountants) or products sold to the Company or a Target do not reduce the amount of funds in the Trust Account to below (i) $10.20
per share of the Offering Shares or (ii) such lesser amount per share of the Offering Shares held in the Trust Account due to
reductions in the value of the trust assets as of the date of the liquidation of the Trust Account, in each case, net of the amount
of interest earned on the property in the Trust Account which may be withdrawn to pay taxes, except as to any claims by a third
party (including a Target) who executed a waiver of any and all rights to seek access to the Trust Account and except as to any
claims under the Company’s indemnity of the Underwriters against certain liabilities, including liabilities under the
Securities Act. In the event that any such executed waiver is deemed to be unenforceable against such third party, the Sponsor shall
not be responsible to the extent of any liability for such third party claims. The Sponsor shall have the right to defend against
any such claim with counsel of its choice reasonably satisfactory to the Company if, within 15 days following written receipt of
notice of the claim to the Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense.

5.                 
To the extent that the Underwriters do not exercise their over-allotment option to purchase up to an additional 600,000 Units within
45 days from the date of the Prospectus (and as further described in the Prospectus), the Founders agree to forfeit, at no cost, a number
of Founder Shares in the aggregate equal to the product of 150,000 multiplied by a fraction, (i) the numerator of which is 600,000 minus
the number of Units purchased by the Underwriters upon the exercise of their over-allotment option, and (ii) the denominator of which
is 600,000. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the Underwriters
so that the Initial Stockholders will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Common Stock after
the Public Offering.


 


6.                 
Intentionally Left Blank.


 


7.                 
The Founders and each Insider hereby agrees and acknowledges that: (i) the Underwriters and the Company would be irreparably injured
in the event of a breach by such Founders or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 6, 8(a), 8(b),
and 10 of this Letter Agreement (ii) monetary damages may not be an adequate remedy for such breach and (iii) the non-breaching party
shall be entitled to injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of
such breach.


 


8.                 
(a) The Founders and each Insider agrees that it or he shall not Transfer 50% of its founder shares until the earlier to occur
of: (A) six months after the completion of the Company’s initial Business Combination, or (B) the date on which the closing price
of the Company’s Common Stock equals or exceeds $12.50 per share (as adjusted for share splits, share dividends, reorganizations
and recapitalizations) for any 20 trading days within any 30-trading day period commencing after the completion of the Company’s
initial Business Combination; and shall not Transfer the remaining 50% of the founder shares until the six months after the completion
of the Company’s initial Business Combination, or earlier, in either case, if, subsequent to the Company’s initial Business
Combination, the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction
that results in all of the Company’s stockholders having the right to exchange their shares of Common Stock for cash, securities
or other property (the “Founder Shares Lock-up Period”).


 









    3


     


    

 


(b) The Founders and each Insider agrees that it,
he or she shall not Transfer any Private Shares until after 30 days after the completion of a Business Combination (the “Private
Shares Lock-up Period”, together with the Founder Shares Lock-up Period, the “Lock-up Periods”).


 


(c) Notwithstanding the provisions set forth in paragraphs
8(a) and (b), Transfers of the Founder Shares, Private Shares that are held by the Founders, any Insider or any of their permitted transferees
(that have complied with this paragraph 8(c)), are permitted (a) to the Company’s officers or directors, any affiliates or family
members of any of the Company’s officers or directors, any affiliates of the Founders, any members of our Founders, or any of its
affiliates, officers, directors, direct and indirect equityholders; (b) in the case of an individual, by gift to a member of the individual’s
immediate family, to a trust, the beneficiary of which is a member of the individual’s immediate family or an affiliate of such
person, or to a charitable organization; (c) in the case of an individual, transfers by virtue of laws of descent and distribution upon
death of the individual; (d) in the case of an individual, transfers pursuant to a qualified domestic relations order; (e) transfers by
private sales or transfers made in connection with the consummation of a Business Combination at prices no greater than the price at which
the securities were originally purchased; (f) transfers in the event of the Company’s liquidation prior to the completion of an
initial Business Combination; and (g) transfers by virtue of the laws of the State of Delaware or the Founders’ governing document
upon dissolution of the Founders; provided, however, that in the case of clauses (a) through (e) or (g), these permitted transferees must
enter into a written agreement agreeing to be bound by the restrictions herein.

10.              
Except as disclosed in the Prospectus and cash or other compensation to the Company’s officers or advisors to be engaged subsequent
to the consummation of the Public Offering (which will be disclosed in the Company’s other filings with the Securities and Exchange
Commission), neither the Founders nor any individual who is an officer, director or advisor of the Company as of the date hereof nor any
affiliate thereof shall receive from the Company any finder’s fee, reimbursement, consulting fee, monies in respect of any repayment
of a loan or other compensation prior to, or in connection with any services rendered in order to effectuate the consummation of the Company’s
initial Business Combination (regardless of the type of transaction that it is), other than the following, none of which will be made
from the proceeds held in the Trust Account prior to the completion of the initial Business Combination: repayment of a loan and advances
up to an aggregate of $400,000 made to the Company by the Founders in connection the preparation of the Public Offering; reimbursement

loans, if any, and on such terms as to be determined by the Company from time to time, made by the Founders or any of the Company’s
officers or directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the
Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may be used
by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment. Up to $1,200,000
of such loans may be convertible into shares of Common Stock at a price of $10.00 per share at the option of the lender (the “Working
Capital Shares”). Such shares would be identical to the Common Stocks included in the units sold in the Public Offering.


 


11.
