Exhibit 4.4

 

WARRANT AGREEMENT

between

TRADEUP ACQUISITION CORP.

and

VSTOCK TRANSFER, LLC

 

Dated [●], 2021

 

This Warrant Agreement (this “Agreement”),
dated [●], 2021, is by and between TradeUP Acquisition Corp., a Delaware corporation (the “Company”), and VStock Transfer,
LLC, a California limited liability company, as warrant agent (the “Warrant Agent”).

 

WHEREAS, the Company is engaged in an initial public
offering (the “Offering”) of units of the Company’s equity securities, each such unit comprised of one share of Common
Stock and one-half of one Warrant (as defined below) (the “Units”) and, in connection therewith, has determined to issue and
deliver up to 2,300,000 redeemable warrants (including up to 300,000 redeemable warrants subject to the Over-allotment Option) to public
investors in the Offering (the “Warrants”). Each whole Warrant entitles the holder thereof to purchase one share of common
stock of the Company, par value $0.0001 per share (“Common Stock”), for $11.50 per share, subject to adjustment as described
herein. Only whole Warrants are exercisable. A holder of the Warrants will not be able to exercise any fraction of a Warrant; and

 

WHEREAS, the Company has filed with the Securities
and Exchange Commission (the “Commission”) registration statement on Form S-1, File No. 333-253322 (the “Registration
Statement”) and a prospectus (the “Prospectus”), for the registration, under the Securities Act of 1933, as amended
(the “Securities Act”), of the Units, the Warrants and the Common Stock included in the Units; and

 

WHEREAS, the Company desires the Warrant Agent
to act on behalf of the Company, and the Warrant Agent is willing to so act, in connection with the issuance, registration, transfer,
exchange, redemption and exercise of the Warrants; and

 

WHEREAS, the Company desires to provide for the
form and provisions of the Warrants, the terms upon which they shall be issued and exercised, and the respective rights, limitation of
rights, and immunities of the Company, the Warrant Agent and the holders of the Warrants; and

 

WHEREAS, all acts and things have been done and
performed which are necessary to make the Warrants, when executed on behalf of the Company and countersigned by or on behalf of the Warrant
Agent (if a physical certificate is issued), as provided herein, the valid, binding and legal obligations of the Company, and to authorize
the execution and delivery of this Agreement.

 

NOW, THEREFORE, in consideration of the mutual
agreements herein contained, the parties hereto agree as follows:

 

1. Appointment of Warrant Agent. The Company hereby
appoints the Warrant Agent to act as agent for the Company for the Warrants, and the Warrant Agent hereby accepts such appointment and
agrees to perform the same in accordance with the terms and conditions set forth in this Agreement.

 

2. Warrants.

2.1 Form of Warrant. Each Warrant shall initially
be issued in registered form only.

 

2.2 Effect of Countersignature. If a physical certificate
is issued, unless and until countersigned by the Warrant Agent pursuant to this Agreement, a certificated Warrant shall be invalid and
of no effect and may not be exercised by the holder thereof.

 

2.3 Registration.

 

2.3.1 Warrant Register. The Warrant Agent shall
maintain books (the “Warrant Register”), for the registration of original issuance and the registration of transfer of the
Warrants. Upon the initial issuance of the Warrants in book -entry form, the Warrant Agent shall issue and register the Warrants in the
names of the respective holders thereof in such denominations and otherwise in accordance with instructions delivered to the Warrant Agent
by the Company. Ownership of beneficial interests in the Warrants shall be shown on, and the transfer of such ownership shall be effected
through, records maintained by institutions that have accounts with The Depository Trust Company (the “Depositary”) (such
institution, with respect to a Warrant in its account, a “Participant”).

 

     

     

    

 

If the Depositary subsequently ceases to make its
book-entry settlement system available for the Warrants, the Company may instruct the Warrant Agent regarding making other arrangements
for book-entry settlement. In the event that the Warrants are not eligible for, or it is no longer necessary to have the Warrants available
in, book-entry form, the Warrant Agent shall provide written instructions to the Depositary to deliver to the Warrant Agent for cancellation
each book-entry Warrant, and the Company shall instruct the Warrant Agent to deliver to the Depositary definitive certificates in physical
form evidencing such Warrants (“Definitive Warrant Certificates”) which shall be in the form annexed hereto
as Exhibit A.

 

 Physical certificates, if issued, shall be
signed by, or bear the facsimile signature of, the Chairman of the Board, Chief Executive Officer, President, Chief Financial Officer,
Chief Operating Officer, General Counsel, Secretary or other principal officer of the Company. In the event the person whose facsimile
signature has been placed upon any Warrant shall have ceased to serve in the capacity in which such person signed the Warrant before such
Warrant is issued, it may be issued with the same effect as if he or she had not ceased to be such at the date of issuance.

 

2.3.2 Registered Holder. Prior to due presentment
for registration of transfer of any Warrant, the Company and the Warrant Agent may deem and treat the person in whose name such Warrant
is registered in the Warrant Register (the “Registered Holder”) as the absolute owner of such Warrant and of each Warrant
represented thereby, for the purpose of any exercise thereof, and for all other purposes, and neither the Company nor the Warrant Agent
shall be affected by any notice to the contrary.

 

2.4 Detachability of Warrants. The Common Stock
and Warrants comprising the Units shall begin separate trading on the 52nd day following the date of the Prospectus or, if such 52nd day
is not on a day, other than a Saturday, Sunday or federal holiday, on which banks in New York City are generally open for normal business
(a “Business Day”), then on the immediately succeeding Business Day following such date, or earlier (the “Detachment
Date”) with the consent of US Tiger Securities, Inc., as representative of the several underwriters, but in no event shall the Common
Stock and the Warrants comprising the Units be separately traded until (a) the Company has filed a Current Report on Form 8-K with the
Commission containing an audited balance sheet of the Company reflecting the receipt by the Company of the gross proceeds of the Offering,
including the proceeds then received by the Company from the exercise by the underwriters of their right to purchase additional Units
in the Offering (the “Over-allotment Option”), if the Over-allotment Option is exercised prior to the filing of the Current
Report on Form 8-K, and (b) the Company issues a press release announcing when such separate trading shall begin.

 

2.5 Fractional Warrants. The Company shall not
issue fractional Warrants other than as part of the Units, each of which is comprised of one share of Common Stock and one-half of one
whole Warrant. If, upon the detachment of Warrants from the Units or otherwise, a holder of Warrants would be entitled to receive a fractional
Warrant, the Company shall round down to the nearest whole number of the number of Warrants to be issued to such holder.  

 

3. Terms and Exercise of Warrants.

 

3.1 Warrant Price. Each whole Warrant shall entitle
the Registered Holder thereof, subject to the provisions of such Warrant and of this Agreement, to purchase from the Company the number
of shares of Common Stock stated therein, at the price of $11.50 per share, subject to the adjustments provided in Section 4 hereof and
in the last sentence of this Section 3.1. The term “Warrant Price” as used in this Agreement shall mean the price per share
(including in cash or by payment of Warrants pursuant to a “cashless exercise,” to the extent permitted hereunder)
described in the prior sentence at which shares of Common Stock may be purchased at the time a Warrant is exercised. The Company in its
sole discretion may lower the Warrant Price at any time prior to the Expiration Date (as defined below) for a period of not less than
fifteen Business Days (unless otherwise required by the Commission, any national securities exchange on which the Warrants are listed
or applicable law); provided, however, that the Company shall provide at least five days’ prior written notice of such reduction
to Registered Holders of the Warrants; and provided further that any such reduction shall be identical among all of the Warrants.

 

3.2 Duration of Warrants. A Warrant may be exercised only during the
period (the “Exercise Period”) (a) commencing on the later of: (i) the date that is thirty (30) days after the first date
on which the Company completes a Business Combination; and (ii) the date that is twelve (12) months from the date of the closing of the
Offering; and (b) terminating at the earliest to occur of: (x) 5:00 p.m., New York City time on the date that is five (5) years after
the date on which the Company completes its initial Business Combination; (y) the liquidation of the Company in accordance with the Company’s
amended and restated memorandum and articles of association, as amended from time to time, if the Company fails to complete a Business
Combination; and (z) 5:00 p.m., New York City time on the Redemption Date (as defined below) as provided in Section 6.2 hereof (the “Expiration
Date”); provided, however, that the exercise of any Warrant shall be subject to the satisfaction of any applicable conditions, as
set forth in subsection 3.3.2 below, with respect to an effective registration statement or a valid exemption therefrom being available.
Except with respect to the right to receive the Redemption Price (as defined below), each Warrant not exercised on or before the Expiration
Date shall become void, and all rights thereunder and all rights in respect thereof under this Agreement shall cease at 5:00 p.m. New
York City time on the Expiration Date. The Company in its sole discretion may extend the duration of the Warrants by delaying the Expiration
Date; provided, however, that the Company shall provide at least twenty (20) days prior written notice of any such extension to
Registered Holders of the Warrants and, provided further that any such extension shall be identical in duration among all the Warrants.

 

     

     

    

 

3.3 Exercise of Warrants.

 

3.3.1 Payment. Subject to the provisions of the
Warrant and this Agreement, a Warrant may be exercised by the Registered Holder thereof by delivering to the Warrant Agent at its corporate
trust department (i) the Definitive Warrant Certificate evidencing the Warrants to be exercised, or, in the case of a Warrant represented
by a book-entry, the Warrants to be exercised (the “Book-Entry Warrants”) on the records of the Depositary to
an account of the Warrant Agent at the Depositary designated for such purposes in writing by the Warrant Agent to the Depositary from
time to time, (ii) an election to purchase (“Election to Purchase”) any Shares of Common Stock pursuant to the
exercise of a Warrant, properly completed and executed by the Registered Holder on the reverse of the Definitive Warrant Certificate or,
in the case of a Book-Entry Warrant, properly delivered by the Participant in accordance with the Depositary’s procedures, and (iii)
the payment in full of the Warrant Price for each full share of Common Stock as to which the Warrant is exercised and any and all applicable
taxes due in connection with the exercise of the Warrant, the exchange of the Warrant for the shares of Common Stock and the issuance
of such shares of Common Stock, as follows:

 

(a) in lawful money of the United States, in good
certified check or good bank draft payable to the order of the Warrant
Agent;

 

(b) in the event of a redemption pursuant to Section
6 hereof in which the Company’s board of directors (the “Board”) has elected to require all holders of the Warrants
to exercise such Warrants on a “cashless basis,” by surrendering the Warrants for that number of Shares
of Common Stock equal to the quotient obtained by dividing (x) the product of the number of Shares
of Common Stock underlying the Warrants, multiplied by the excess of the “Fair Market Value”, as defined in this subsection
3.3.1(b), over the Warrant Price by (y) the Fair Market Value. Solely for purposes of this subsection 3.3.1(b) and Section 6.2,
the “Fair Market Value” shall mean the average last reported sale price of the Common Stock for the ten (10) trading days
ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of the Warrants, pursuant to
Section 6 hereof; or 

 

(c) as provided
in Section 7.4 hereof.

 

3.3.2 Issuance of Shares of Common Stock on Exercise.
As soon as practicable after the exercise of any Warrant and the clearance of the funds in payment of the Warrant Price (if payment is
pursuant to subsection 3.3.1(a)), the Company shall issue to the Registered Holder of such Warrant a book-entry position or certificate,
as applicable, for the number of full shares of Common Stock to which he, she or it is entitled, registered in such name or names as may
be directed by him, her or it , and if such Warrant shall not have been exercised in full, a new book-entry position or countersigned
Warrant, as applicable, for the number of shares of Common Stock as to which such Warrant shall not have been exercised. Notwithstanding
the foregoing, the Company shall not be obligated to deliver any shares of Common Stock pursuant to the exercise of a Warrant and shall
have no obligation to settle such Warrant exercise unless a registration statement under the Securities Act with respect to the shares
of Common Stock underlying the Warrants is then effective and a prospectus relating thereto is current, subject to the Company’s
satisfying its obligations under Section 7.4 or a valid exemption from registration is available. No Warrant shall be exercisable and
the Company shall not be obligated to issue shares of Common Stock upon exercise of a Warrant unless the shares of Common Stock issuable
upon such Warrant exercise have been registered, qualified or deemed to be exempt from registration or qualification under the securities
laws of the state of residence of the Registered Holder of the Warrants. Subject to Section 4.6 of this Agreement, a Registered
Holder of Warrants may exercise its Warrants only for a whole number of shares of Common Stock. The Company may require holders of Warrants
to settle the Warrant on a “cashless basis” pursuant to Section 7.4. If, by reason of any exercise of Warrants on a “cashless
basis”, the holder of any Warrant would be entitled, upon the exercise of such Warrant, to receive a fractional interest in a share
of Common Stock, the Company shall round down to the nearest whole number, the number of shares of Common Stock to be issued to such holder.

 

3.3.3 Valid Issuance. All shares of Common Stock
issued upon the proper exercise of a Warrant in conformity with this Agreement shall be validly issued, fully paid and nonassessable.

 

3.3.4 Date of Issuance. Each person in whose name
any book-entry position or certificate, as applicable, for shares of Common Stock is issued shall for all purposes be deemed to have become
the holder of record of such shares of Common Stock on the date on which the Warrant, or book-entry position representing such Warrant,
was surrendered and payment of the Warrant Price was made, irrespective of the date of delivery of such certificate in the case of a certificated
Warrant, except that, if the date of such surrender and payment is a date when the share transfer books of the Company or book-entry system
of the Warrant Agent are closed, such person shall be deemed to have become the holder of such shares of Common Stock at the close of
business on the next succeeding date on which the share transfer books or book-entry system are open.

 

     

     

    

 

 3.3.5 Maximum Percentage. A holder of a Warrant
may notify the Company in writing in the event it elects to be subject to the provisions contained in this subsection 3.3.5; however,
no holder of a Warrant shall be subject to this subsection 3.3.5 unless he, she or it makes such election. If the election is made by
a holder, the Warrant Agent shall not effect the exercise of the holder’s Warrant, and such holder shall not have the right to exercise
such Warrant, to the extent that after giving effect to such exercise, such person (together with such person’s affiliates), to
the Warrant Agent’s actual knowledge, would beneficially own in excess of 9.8% (the “Maximum Percentage”) of the Shares
of Common Stock outstanding immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number
of shares of Common Stock beneficially owned by such person and its affiliates shall include the number of shares of Common Stock issuable
upon exercise of the Warrant with respect to which the determination of such sentence is being made, but shall exclude shares of Common
Stock that would be issuable upon (x) exercise of the remaining, unexercised portion of the Warrant beneficially owned by such person
and its affiliates and (y) exercise or conversion of the unexercised or unconverted portion of any other securities of the Company beneficially
owned by such person and its affiliates (including, without limitation, any convertible notes or convertible preferred stock or warrants)
subject to a limitation on conversion or exercise analogous to the limitation contained herein. Except as set forth in the preceding sentence,
for purposes of this paragraph, beneficial ownership shall be calculated in accordance with Section 13(d) of the Securities Exchange Act
of 1934, as amended (the “Exchange Act”). For purposes of the Warrant, in determining the number of outstanding
shares of Common Stock, the holder may rely on the number of outstanding shares of Common Stock as reflected in (1) the Company’s
most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q, Current Report on Form 8-K or other public filing with the Commission
as the case may be, (2) a more recent public announcement by the Company or (3) any other notice by the Company or VStock Transfer, LLC,
as transfer agent, (in such capacity, the “Transfer Agent”) setting forth the number of shares of Common Stock outstanding.
For any reason at any time, upon the written request of the holder of the Warrant, the Company shall, within two (2) Business Days, confirm
orally and in writing to such holder the number of shares of Common Stock then outstanding. In any case, the number of issued and outstanding
shares of Common Stock shall be determined after giving effect to the conversion or exercise of equity securities of the Company by the
holder and its affiliates since the date as of which such number of issued and outstanding shares of Common Stock was reported. By written
notice to the Company, the holder of a Warrant may from time to time increase or decrease the Maximum Percentage applicable to such holder
to any other percentage specified in such notice; provided, however, that any such increase shall not be effective until the sixty-first
(61st) day after such notice is delivered to the Company.

 

4. Adjustments.

 

4.1 Share Capitalizations.

 

4.1.1 Split-Ups. If after the date hereof, and
subject to the provisions of Section 4.6 below, the number of issued and outstanding shares of Common Stock is increased by a capitalization
or stock dividend of Shares of common stock, or by a split-up of shares of Common Stock or other similar event, then, on the effective
date of such capitalization, stock dividend, split-up or similar event, the number of shares of Common Stock issuable on exercise of
each Warrant shall be increased in proportion to such increase in the issued and outstanding shares of Common Stock. A rights offering
made to all or substantially all holders of shares of Common Stock entitling holders to purchase shares of Common Stock at a price less
than the “Historical Fair Market Value” (as defined below) shall be deemed a capitalization of a number of shares of Common
Stock equal to the product of (i) the number of shares of Common Stock actually sold in such rights offering (or issuable under any other
equity securities sold in such rights offering that are convertible into or exercisable for the Common Stock) multiplied by (ii) one
(1) minus the quotient of (x) the price per share of Common Stock paid in such rights offering divided by (y) the Historical Fair Market
Value. For purposes of this subsection 4.1.1, (i) if the rights offering is for securities convertible into or exercisable for Common
Stock, in determining the price payable for Common Stock, there shall be taken into account any consideration received for such rights,
as well as any additional amount payable upon exercise or conversion and (ii) “Historical Fair Market Value”
means the volume weighted average price of the Common Stock as reported during the ten (10) trading day period ending on the trading
day prior to the first date on which the shares of Common Stock trade on the applicable exchange or in the applicable market, regular
way, without the right to receive such rights. No Shares of Common Stock shall be issued at less than their par value.

 

4.1.2 Extraordinary Dividends. If the Company,
at any time while the Warrants are outstanding and unexpired, pays to all or substantially all of the holders of the Shares of Common
Stock a dividend or make a distribution in cash, securities or other assets on account of such Shares of Common Stock (or other shares
into which the Warrants are convertible), other than (a) as described in subsection 4.1.1 above, (b) Ordinary Cash Dividends (as defined
below), (c) to satisfy the redemption rights of the holders of the Common Stock in connection with a proposed initial Business Combination,
(d) to satisfy the redemption rights of the holders of Common Stock in connection with a stockholder vote to amend the Company’s
amended and restated certificate of incorporation (i) to affect the substance or timing of the Company’s obligation to provide for
the redemption of shares of Common Stock in connection with an initial Business Combination or to redeem 100% of the Company’s public
shares if the Company does not consummate its initial Business Combination within 18 months from the closing of the Offering, or in connection
with the redemption of public shares upon the failure of the Company to complete its initial Business Combination and any subsequent distribution
of its assets upon its liquidation (any such non-excluded event being referred to herein as an “Extraordinary Dividend”),
then the Warrant Price shall be decreased, effective immediately after the effective date of such Extraordinary Dividend, by the amount
of cash and/or the fair market value (as determined by the Company’s board of directors (the “Board”),
in good faith) of any securities or other assets paid on each share of Common Stock in respect of such Extraordinary Dividend. For purposes
of this subsection 4.1.2, “Ordinary Cash Dividends” means any cash dividend or cash distribution which, when combined on a
per share basis, with the per share amounts of all other cash dividends and cash distributions paid on the Common Stock during the 365-day
period ending on the date of declaration of such dividend or distribution to the extent it does not exceed $0.50 (which amount shall be
adjusted to appropriately reflect any of the events referred to in other subsections of this Section 4 and excluding cash dividends or
cash distributions that resulted in an adjustment to the Warrant Price or to the number of shares of Common Stock issuable on exercise
of each Warrant).

  

     

     

    

 

4.2 Aggregation of Shares. If after the date hereof,
and subject to the provisions of Section 4.6 hereof, the number of issued and outstanding shares of Common Stock is decreased by a consolidation,
combination, reverse stock split or reclassification of shares of Common Stock or other similar event, then, on the effective date of
such consolidation, combination, reverse stock split, reclassification or similar event, the number of shares of Common Stock issuable
on exercise of each Warrant shall be decreased in proportion to such decrease in issued and outstanding shares of Common Stock.

 

4.3 Adjustments in Exercise Price. Whenever the
number of shares of Common Stock purchasable upon the exercise of the Warrants is adjusted, as provided in subsection 4.1.1 or Section
4.2 above, the Warrant Price shall be adjusted (to the nearest cent) by multiplying such Warrant Price immediately prior to such adjustment
by a fraction (x) the numerator of which shall be the number of shares of Common Stock purchasable upon the exercise of the Warrants immediately
prior to such adjustment, and (y) the denominator of which shall be the number of shares of Common Stock so purchasable immediately thereafter.

   

4.4 [Reserved]

 

4.5 Replacement of Securities upon Reorganization,
etc. In case of any reclassification or reorganization of the issued and outstanding shares of Common Stock (other than a change covered
by Section 4.1 or Section 4.2 hereof or that solely affects the par value of such shares of Common Stock), or in the case of any
merger or consolidation of the Company with or into another entity (other than a consolidation or merger in which the Company is the continuing
corporation and that does not result in any reclassification or reorganization of the issued and outstanding shares of Common Stock),
or in the case of any sale or conveyance to another corporation or entity of the assets or other property of the Company as an entirety
or substantially as an entirety in connection with which the Company is dissolved, the Registered Holder of the Warrants shall thereafter
have the right to purchase and receive, upon the basis and upon the terms and conditions specified in the Warrants and in lieu of the
shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the rights represented thereby,
the kind and amount of shares or stock or other securities or property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, or upon a dissolution following any such sale or transfer, that the holder of the Warrants would have received
if such holder had exercised his, her or its Warrant(s) immediately prior to such event; and if any reclassification or reorganization
also results in a change in shares of Common Stock covered by Section 4.1 or Section 4.2, then such adjustment shall be
made pursuant to Sections 4.1, 4.2, 4.3 and this Section 4.5. The provisions of this Section 4.5 shall similarly
apply to successive reclassifications, reorganizations, mergers or consolidations, sales or other transfers. In no event shall the Warrant
Price be reduced to less than the par value per share issuable upon exercise of such Warrant.

   

4.6 Notices of Changes in Warrant. Upon every adjustment of the Warrant
Price or the number of shares of Common Stock issuable upon exercise of a Warrant, the Company shall give written notice thereof to the
Warrant Agent, which notice shall state the Warrant Price resulting from such adjustment and the increase or decrease, if any, in the
number of shares of Common Stock purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method
of calculation and the facts upon which such calculation is based. Upon the occurrence of any event specified in Sections 4.1, 4.2, 4.3,
or 4.5, the Company shall give written notice of the occurrence of such event to each holder of a Warrant, at the last address
set forth for such holder in the Warrant Register, of the record date or the effective date of the event. Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such event.

 

4.7 No Fractional Shares. Notwithstanding any provision
contained in this Agreement to the contrary, the Company shall not issue fractional shares of Common Stock upon the exercise of Warrants.
If, by reason of any adjustment made pursuant to this Section 4, the holder of any Warrant would be entitled, upon the exercise of such
Warrant, to receive a fractional interest in a share, the Company shall, upon such exercise, round down to the nearest whole number the
number of shares of Common Stock to be issued to such holder.

 

4.8 Form of Warrant. The form of Warrant need not
be changed because of any adjustment pursuant to this Section 4, and Warrants issued after such adjustment may state the same Warrant
Price and the same number of shares of Common Stock as is stated in the Warrants initially issued pursuant to this Agreement; provided,
however, that the Company may at any time in its sole discretion make any change in the form of Warrant that the Company may deem appropriate
and that does not affect the substance thereof, and any Warrant thereafter issued or countersigned, whether in exchange or substitution
for an outstanding Warrant or otherwise, may be in the form as so changed.

 

     

     

    

 

5. Transfer and Exchange of Warrants.

 

5.1 Registration of Transfer. The Warrant Agent
shall register the transfer, from time to time, of any outstanding Warrant upon the Warrant Register, upon surrender of such Warrant for
transfer, properly endorsed with signatures properly guaranteed and accompanied by appropriate instructions for transfer. Upon any such
transfer, a new Warrant representing an equal aggregate number of Warrants shall be issued and the old Warrant shall be cancelled by the
Warrant Agent. In the case of certificated Warrants, the Warrants so cancelled shall be delivered by the Warrant Agent to the Company
from time to time upon request.

 

5.2 Procedure for Surrender of Warrants. Warrants
may be surrendered to the Warrant Agent, together with a written request for exchange or transfer, and thereupon the Warrant Agent shall
issue in exchange therefor one or more new Warrants as requested by the Registered Holder of the Warrants so surrendered, representing
an equal aggregate number of Warrants; provided, however, that except as otherwise provided herein or with respect to any Book-Entry Warrant,
each Book-Entry Warrant may be transferred only in whole and only to the Depositary, to another nominee of the Depositary, to a successor
depository, or to a nominee of a successor depository; provided further that in the event that a Warrant surrendered for transfer
bears a restrictive legend, the Warrant Agent shall not cancel such Warrant and issue new Warrants in exchange thereof until the Warrant
Agent has received an opinion of counsel for the Company stating that such transfer may be made and indicating whether the new Warrants
must also bear a restrictive legend.

 

5.3 Fractional
Warrants. The Warrant Agent shall not be required to effect any registration of transfer or exchange which shall result in the issuance
of a warrant certificate or book-entry position for a fraction of a warrant, except as part of the Units.

 

5.4 Service Charges. No service charge shall be
made for any exchange or registration of transfer of Warrants.

 

5.5 Warrant Execution and Countersignature. The
Warrant Agent is hereby authorized to countersign and to deliver, in accordance with the terms of this Agreement, the Warrants required
to be issued pursuant to the provisions of this Section 5, and the Company, whenever required by the Warrant Agent, shall supply the Warrant
Agent with Warrants duly executed on behalf of the Company for such purpose.

 

5.6 Transfer of Warrants. Prior to the Detachment
Date, the Warrants may be transferred or exchanged only together with the Unit in which such Warrant is included, and only for the purpose
of effecting, or in conjunction with, a transfer or exchange of such Unit. Furthermore, each transfer of a Unit on the register relating
to such Units shall operate also to transfer the Warrants included in such Unit. Notwithstanding the foregoing, the provisions of this
Section 5.6 shall have no effect on any transfer of Warrants on and after the Detachment Date.

 

6. Redemption.

 

6.1 Redemption of Warrants for Cash. All, but not
less than all, of the outstanding Warrants may be redeemed, at the option of the Company, at any time during the Exercise Period, at the
office of the Warrant Agent, upon notice to the Registered Holders of the Warrants, as described in Section 6.2 below, at a Redemption
Price of $0.01 per Warrant, provided that (a) the Reference Value equals or exceeds $16.50 per share (subject to adjustment in compliance
with Section 4 hereof) and (b) there is an effective registration statement covering the issuance of shares of Common Stock issuable upon
exercise of the Warrants, and a current prospectus relating thereto, available throughout the 30-day Redemption Period (as defined in
Section 6.2 below).

   

6.2 Date Fixed for, and Notice of, Redemption;
Redemption Price; Reference Value. In the event that the Company elects to redeem the Warrants pursuant to Sections 6.1, the
Company shall fix a date for the redemption (the “Redemption Date”). Notice of redemption shall be mailed by first class mail,
postage prepaid, by the Company not less than thirty (30) days prior to the Redemption Date (the “30-day Redemption Period”)
to the Registered Holders of the Warrants to be redeemed at their last addresses as they shall appear on the registration books. Any notice
mailed in the manner herein provided shall be conclusively presumed to have been duly given whether or not the Registered Holder received
such notice. As used in this Agreement, (a) “Redemption Price” shall mean the price per Warrant at which any
Warrants are redeemed pursuant to Sections 6.1 and (b) “Reference Value” shall mean the last reported
sales price of Common Stock for any twenty (20) trading days within the thirty (30) trading-day period ending on the third trading day
prior to the date on which notice of the redemption is given.

 

     

     

    

 

6.3 Exercise After Notice of Redemption.
The Warrants may be exercised, for cash (or on a “cashless basis” in accordance with Section 3.3.1(b) of this Agreement)
at any time after notice of redemption shall have been given by the Company pursuant to Section 6.2 hereof and prior to the Redemption
Date. On and after the Redemption Date, the record holder of the Warrants shall have no further rights except to receive, upon surrender
of the Warrants, the Redemption Price.

 

7. Other Provisions Relating to Rights of Holders
of Warrants.

 

7.1 No Rights as Stockholder. A Warrant does not
entitle the Registered Holder thereof to any of the rights of a stockholder of the Company, including, without limitation, the right to
receive dividends, or other distributions, exercise any preemptive rights to vote or to consent or to receive notice as a stockholder
in respect of the meetings of stockholders or the election of directors of the Company or any other matter.

 

7.2 Lost, Stolen, Mutilated, or Destroyed Warrants.
If any Warrant is lost, stolen, mutilated, or destroyed, the Company and the Warrant Agent may on such terms as to indemnity or otherwise
as they may in their discretion impose (which shall, in the case of a mutilated Warrant, include the surrender thereof), issue a new Warrant
of like denomination, tenor, and date as the Warrant so lost, stolen, mutilated, or destroyed. Any such new Warrant shall constitute a
substitute contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant shall be
at any time enforceable by anyone.

  

7.3 Reservation of Common Stock. The Company shall
at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that shall be sufficient to permit
the exercise in full of all outstanding Warrants issued pursuant to this Agreement.

 

7.4 Registration of Common Stock; Cashless Exercise
at Company’s Option.

 

7.4.1 Registration of the Common Stock. The Company
agrees that as soon as practicable, but in no event later than thirty (30) Business Days after the closing of its initial Business Combination,
it shall use its commercially reasonable efforts to file with the Commission a registration statement for the registration, under the
Securities Act, of the shares of Common Stock issuable upon exercise of the Warrants. The Company shall use its commercially reasonable
efforts to cause the same to become effective within sixty (60) Business Days following the closing of its initial Business Combination
and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration or redemption
of the Warrants in accordance with the provisions of this Agreement. If any such registration statement has not been declared effective
by the sixtieth (60th) Business Day following the closing of the Business Combination, holders of the Warrants shall have the right, during
the period beginning on the sixty-first (61st) Business Day after the closing of the Business Combination and ending upon such registration
statement being declared effective by the Commission, and during any other period when the Company shall fail to have maintained an effective
registration statement covering the issuance of the shares of Common Stock issuable upon exercise of the Warrants, to exercise such Warrants
on a “cashless basis,” by exchanging the Warrants (in accordance with Section 3(a)(9) of the Securities Act or another exemption)
for that number of shares of Common Stock equal to the quotient obtained by dividing (x) the product of the number of shares of Common
Stock underlying the Warrants, multiplied by the excess of the “Fair Market Value” (as defined below) over the Warrant Price
by (y) the Fair Market Value. Solely for purposes of this subsection 7.4.1, “Fair Market Value” shall mean the volume -weighted
average price of the Common Stock as reported during the ten (10) trading day period ending on the trading day prior to the date that
notice of exercise is received by the Warrant Agent from the holder of such Warrants or its securities broker or intermediary. The date
that notice of “cashless exercise” is received by the Warrant Agent shall be conclusively determined by the Warrant Agent.
In connection with the “cashless exercise” of a Warrant, the Company shall, upon request, provide the Warrant Agent with an
opinion of counsel for the Company (which shall be an outside law firm with securities law experience) stating that (i) the exercise of
the Warrants on a “cashless basis” in accordance with this subsection 7.4.1 is not required to be registered under the Securities
Act and (ii) the shares of Common Stock issued upon such exercise shall be freely tradable under United States federal securities laws
by anyone who is not an affiliate (as such term is defined in Rule 144 under the Securities Act) of the Company and, accordingly, shall
not be required to bear a restrictive legend. Except as provided in subsection 7.4.2, for the avoidance of doubt, unless and until all
of the Warrants have been exercised or have expired, the Company shall continue to be obligated to comply with its registration obligations
under the first three sentences of this subsection 7.4.1.

 

7.4.2 Cashless Exercise at Company’s Option.
If the Common Stock is at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the
definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, (i) require
holders of Warrants who exercise Warrants to exercise such Warrants on a “cashless basis” in accordance with Section 3(a)(9)
of the Securities Act as described in subsection 7.4.1 and (ii) in the event the Company so elects, the Company shall (x) not be required
to file or maintain in effect a registration statement for the registration, under the Securities Act, of the Common Stock issuable upon
exercise of the Warrants, notwithstanding anything in this Agreement to the contrary, and (y) use its commercially reasonable efforts
to register or qualify for sale the Common Stock issuable upon exercise of the Warrant under applicable blue sky laws to the extent an
exemption is not available.

   

     

     

    

 

8. Concerning the Warrant Agent and Other Matters.

 

8.1 Payment of Taxes. The Company shall from time
to time promptly pay all taxes and charges that may be imposed upon the Company or the Warrant Agent in respect of the issuance or delivery
of shares of Common Stock upon the exercise of the Warrants, but the Company shall not be obligated to pay any transfer taxes in respect
of the Warrants or such shares.

 

8.2 Resignation, Consolidation, or Merger of Warrant
Agent.

 

8.2.1 Appointment of Successor Warrant Agent. The
Warrant Agent, or any successor to it hereafter appointed, may resign its duties and be discharged from all further duties and liabilities
hereunder after giving sixty (60) days’ notice in writing to the Company. If the office of the Warrant Agent becomes vacant by resignation
or incapacity to act or otherwise, the Company shall appoint in writing a successor Warrant Agent in place of the Warrant Agent. If the
Company shall fail to make such appointment within a period of thirty (30) days after it has been notified in writing of such resignation
or incapacity by the Warrant Agent or by the holder of a Warrant (who shall, with such notice, submit his, her or its Warrant for inspection
by the Company), then the holder of any Warrant may apply to the Supreme Court of the State of New York for the County of New York for
the appointment of a successor Warrant Agent at the Company’s cost. Any successor Warrant Agent, whether appointed by the Company
or by such court, shall be a corporation or other entity organized and existing under the laws of the State of New York, in good standing
and having its principal office in the United States of America, and authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by federal or state authority. After appointment, any successor Warrant Agent shall be vested with
all the authority, powers, rights, immunities, duties, and obligations of its predecessor Warrant Agent with like effect as if originally
named as Warrant Agent hereunder, without any further act or deed; but if for any reason it becomes necessary or appropriate, the predecessor
Warrant Agent shall execute and deliver, at the expense of the Company, an instrument transferring to such successor Warrant Agent all
the authority, powers, and rights of such predecessor Warrant Agent hereunder; and upon request of any successor Warrant Agent the Company
shall make, execute, acknowledge, and deliver any and all instruments in writing for more fully and effectually vesting in and confirming
to such successor Warrant Agent all such authority, powers, rights, immunities, duties, and obligations.

 

8.2.2 Notice of Successor Warrant Agent. In the
event a successor Warrant Agent shall be appointed, the Company shall give notice thereof to the predecessor Warrant Agent and the Transfer
Agent for the Common Stock not later than the effective date of any such appointment.

   

8.2.3 Merger or Consolidation of Warrant Agent.
Any entity into which the Warrant Agent may be merged or with which it may be consolidated or any entity resulting from any merger or
consolidation to which the Warrant Agent shall be a party shall be the successor Warrant Agent under this Agreement without any further
act.

 

8.3 Fees and Expenses of Warrant Agent.

 

8.3.1 Remuneration. The Company agrees to pay the
Warrant Agent reasonable remuneration for its services as such Warrant Agent hereunder and shall, pursuant to its obligations under this
Agreement, reimburse the Warrant Agent upon demand for all expenditures that the Warrant Agent may reasonably incur in the execution of
its duties hereunder.

 

8.3.2 Further Assurances. The Company agrees to
perform, execute, acknowledge, and deliver or cause to be performed, executed, acknowledged, and delivered all such further and other
acts, instruments, and assurances as may reasonably be required by the Warrant Agent for the carrying out or performing of the provisions
of this Agreement.

 

8.4 Liability of Warrant Agent.

 

8.4.1 Reliance on Company Statement. Whenever in
the performance of its duties under this Agreement, the Warrant Agent shall deem it necessary or desirable that any fact or matter be
proved or established by the Company prior to taking or suffering any action hereunder, such fact or matter (unless other evidence in
respect thereof be herein specifically prescribed) may be deemed to be conclusively proved and established by a statement signed by the
Chief Executive Officer, the President, the Chief Financial Officer, Chief Operating Officer, the General Counsel, the Secretary or the
Chairman of the Board of the Company and delivered to the Warrant Agent. The Warrant Agent may rely upon such statement for any action
taken or suffered in good faith by it pursuant to the provisions of this Agreement.

 

8.4.2 Indemnity. The Warrant Agent shall be liable
hereunder only for its own gross negligence, willful misconduct, fraud or bad faith. The Company agrees to indemnify the Warrant Agent
and save it harmless against any and all liabilities, including judgments, out-of-pocket costs and reasonable outside counsel fees, for
anything done or omitted by the Warrant Agent in the execution of this Agreement, except as a result of the Warrant Agent’s gross
negligence, willful misconduct, fraud or bad faith.

 

8.4.3 Exclusions. The Warrant Agent shall have
no responsibility with respect to the validity of this Agreement or with respect to the validity or execution of any Warrant (except its
countersignature thereof). The Warrant Agent shall not be responsible for any breach by the Company of any covenant or condition contained
in this Agreement or in any Warrant. The Warrant Agent shall not be responsible to make any adjustments required under the provisions
of Section 4 hereof or responsible for the manner, method, or amount of any such adjustment or the ascertaining of the existence of facts
that would require any such adjustment; nor shall it by any act hereunder be deemed to make any representation or warranty as to the authorization
or reservation of any shares of Common Stock to be issued pursuant to this Agreement or any Warrant or as to whether any shares of Common
Stock shall, when issued, be valid and fully paid and nonassessable.

 

     

     

    

 

8.4.4 Acceptance of Agency. The Warrant Agent hereby accepts the agency
established by this Agreement and agrees to perform the same upon the terms and conditions herein set forth and among other things, shall
account promptly to the Company with respect to Warrants exercised and concurrently account for, and pay to the Company, all monies received
by the Warrant Agent for the purchase of shares of Common Stock through the exercise of the Warrants.

   

8.4.5 Waiver. The Warrant Agent has no right of
set-off or any other right, title, interest or claim of any kind (“Claim”) in, or to any distribution of, the Trust Account
(as defined in that certain Investment Management Trust Agreement, dated as of the date hereof, by and between the Company and Wilmington
Trust Company as trustee thereunder) and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against
the Trust Account for any reason whatsoever. The Warrant Agent hereby waives any and all Claims against the Trust Account and any and
all rights to seek access to the Trust Account.

 

9. Miscellaneous Provisions.

 

9.1 Successors. All the covenants and provisions
of this Agreement by or for the benefit of the Company or the Warrant Agent shall bind and inure to the benefit of their respective successors
and assigns.

 

9.2 Notices. Any notice, statement or demand authorized
by this Agreement to be given or made by the Warrant Agent or by the holder of any Warrant to or on the Company shall be sufficiently

9.3 Applicable Law and Exclusive Forum.
The validity, interpretation, and performance of this Agreement and of the Warrants shall be governed in all respects by the laws of the
State of New York. Subject to applicable law, the Company hereby agrees that any action, proceeding or claim against it arising out of
or relating in any way to this Agreement shall be brought and enforced in the courts of the State of New York or the United States District
Court for the Southern District of New York, and irrevocably submits to such jurisdiction, which jurisdiction shall be exclusive forum

any liability or duty created by the Exchange Act or any other claim for which the federal district courts of the United States of America
are the sole and exclusive forum.

   

Any person or entity purchasing or otherwise acquiring
any interest in the Warrants shall be deemed to have notice of and to have consented to the forum provisions in this Section 9.3. If any
action, the subject matter of which is within the scope the forum provisions above, is filed in a court other than a court located within
the State of New York or the United States District Court for the Southern District of New York (a “foreign action”) in the
name of any warrant holder, such warrant holder shall be deemed to have consented to: (x) the personal jurisdiction of the state and federal
courts located within the State of New York or the United States District Court for the Southern District of New York in connection with
any action brought in any such court to enforce the forum provisions (an “enforcement action”), and (y) having service of
process made upon such warrant holder in any such enforcement action by service upon such warrant holder’s counsel in the foreign
action as agent for such warrant holder.

of the Warrants.

 

9.5 Examination of the Warrant Agreement. A copy
of this Agreement shall be available at all reasonable times at the office of the Warrant Agent in the United States of America, for inspection
by the Registered Holder of any Warrant. The Warrant Agent may require any such holder to submit such holder’s Warrant for inspection
by the Warrant Agent.

 

9.6 Counterparts. This Agreement may be executed
in any number of original or facsimile counterparts and each of such counterparts shall for all purposes be deemed to be an original,
and all such counterparts shall together constitute but one and the same instrument.

 

9.7 Effect of Headings. The section headings herein
are for convenience only and are not part of this Agreement and shall not affect the interpretation thereof.

 

9.8 Amendments. This Agreement may be amended by
the parties hereto without the consent of any Registered Holder for the purpose of (i) curing any ambiguity or to correct any mistake,
including to conform the provisions hereof to the description of the terms of the Warrants and this Agreement set forth in the Prospectus,
or defective provision contained herein, (ii) amending the definition of “Ordinary Cash Dividend” as contemplated by and in
accordance with the second sentence of subsection 4.1.2or (iii)adding or changing any provisions with respect to matters or questions
arising under this Agreement as the parties may deem necessary or desirable and that the parties deem shall not adversely affect the rights

severable, and the invalidity or unenforceability of any term or provision hereof shall not affect the validity or enforceability of this
Agreement or of any other term or provision hereof. Furthermore, in lieu of any such invalid or unenforceable term or provision, the parties
hereto intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision

Warrant Certificate

 

This Warrant Certificate certifies that [], or
registered assigns, is the registered holder of [ ] warrant(s) (the “Warrants” and each, a “Warrant”) to purchase
shares of common stock, $0.0001 par value per share (“Common Stock”), of TradeUP Acquisition Corp., a Delaware corporation
(the “Company”). Each Warrant entitles the holder, upon exercise during the period set forth in the Warrant Agreement referred
to below, to receive from the Company that number of fully paid and nonassessable shares of Common Stock as set forth below, at the exercise
price (the “Exercise Price”) as determined pursuant to the Warrant Agreement, payable in lawful money (or through “cashless
exercise” as provided for in the Warrant Agreement) of the United States of America upon surrender of this Warrant Certificate and
payment of the Exercise Price at the office or agency of the Warrant Agent referred to below, subject to the conditions set forth herein
and in the Warrant Agreement. Defined terms used in this Warrant Certificate but not defined herein shall have the meanings given to them
in the Warrant Agreement.

 

Each whole Warrant is initially exercisable for
one fully paid and non-assessable share of Common Stock. No fractional. Fractional shares shall not be issued upon exercise of any Warrant.
If, upon the exercise of Warrants, a holder would be entitled to receive a fractional interest in a share, the Company shall, upon exercise,
round down to the nearest whole number the number of shares of Common Stock to be issued to the Warrant holder. The number of shares of
Common Stock issuable upon exercise of the Warrants is subject to adjustment upon the occurrence of certain events as set forth in the
Warrant Agreement.

 

The initial Exercise Price per share of Common
Stock for any Warrant is equal to $11.50 per share. The Exercise Price is subject to adjustment upon the occurrence of certain events
as set forth in the Warrant Agreement.

 

Subject to the conditions set forth in the Warrant
Agreement, the Warrants may be exercised only during the Exercise Period and to the extent not exercised by the end of such Exercise Period,
such Warrants shall become void. The Warrants may be redeemed, subject to certain conditions, as set forth in the Warrant Agreement.

[Form of Warrant Certificate]

The Warrants evidenced by this Warrant Certificate
are part of a duly authorized issue of Warrants entitling the holder on exercise to receive shares of Common Stock and are issued or to
be issued pursuant to a Warrant Agreement dated as of [●], 2021 (the “Warrant Agreement”), duly executed and delivered
by the Company to VStock Transfer, LLC, a California limited liability company, as warrant agent (the “Warrant Agent”), which
Warrant Agreement is hereby incorporated by reference in and made a part of this instrument and is hereby referred to for a description
of the rights, limitation of rights, obligations, duties and immunities thereunder of the Warrant Agent, the Company and the holders (the
words “holders” or “holder” meaning the Registered Holders or Registered Holder, respectively) of the Warrants.
A copy of the Warrant Agreement may be obtained by the holder hereof upon written request to the Company. Defined terms used in this Warrant
Certificate but not defined herein shall have the meanings given to them in the Warrant Agreement.

 

Warrants may be exercised at any time during the
Exercise Period set forth in the Warrant Agreement. The holder of Warrants evidenced by this Warrant Certificate may exercise them by
surrendering this Warrant Certificate, with the form of Election to Purchase set forth hereon properly completed and executed, together
with payment of the Exercise Price as specified in the Warrant Agreement (or through “cashless exercise” as provided for in
the Warrant Agreement) at the principal corporate trust office of the Warrant Agent. In the event that upon any exercise of Warrants evidenced
hereby the number of Warrants exercised shall be less than the total number of Warrants evidenced hereby, there shall be issued to the
holder hereof or his, her or its assignee, a new Warrant Certificate evidencing the number of Warrants not exercised.

 

Notwithstanding anything else in this Warrant Certificate
or the Warrant Agreement, no Warrant may be exercised unless at the time of exercise (i) a registration statement covering the issuance
of the shares of Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating
to the shares of Common Stock is current, except through “cashless exercise” as provided for in the Warrant Agreement.

 

The Warrant Agreement provides that upon the occurrence
of certain events the number of shares of Common Stock issuable upon exercise of the Warrants set forth on the face hereof may, subject
to certain conditions, be adjusted. If, upon exercise of a Warrant, the holder thereof would be entitled to receive a fractional interest
in a share of Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Common Stock to be issued
to the holder of the Warrant.

 

Warrant Certificates, when surrendered at the principal
corporate trust office of the Warrant Agent by the Registered Holder thereof in person or by legal representative or attorney duly authorized
in writing, may be exchanged, in the manner and subject to the limitations provided in the Warrant Agreement, but without payment of any
service charge, for another Warrant Certificate or Warrant Certificates of like tenor evidencing in the aggregate a like number of Warrants.

 

    	 	 A-4	 

     

    

 

Upon due presentation for registration of transfer
of this Warrant Certificate at the office of the Warrant Agent a new Warrant Certificate or Warrant Certificates of like tenor and evidencing
in the aggregate a like number of Warrants shall be issued to the transferee(s) in exchange for this Warrant Certificate, subject to the
limitations provided in the Warrant Agreement, without charge except for any tax or other governmental charge imposed in connection therewith.

   

The Company and the Warrant Agent may deem and
treat the Registered Holder(s) hereof as the absolute owner(s) of this Warrant Certificate (notwithstanding any notation of ownership
or other writing hereon made by anyone), for the purpose of any exercise hereof, of any distribution to the holder(s) hereof, and for
all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary. Neither the Warrants
nor this Warrant Certificate entitles any holder hereof to any rights of a tockholder of the Company.

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 Inc. 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) $10.00
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.              
Each of the Founders and each Insider has full right and power, without violating any agreement to which it is bound (including, without
