Exhibit 4.4


 


WARRANT AGREEMENT


 


TRADEUP 88 CORP.


 


and


 


VSTOCK TRANSFER, LLC


 


Dated [_______], 2021


 


This Warrant Agreement (this
 “Agreement”), dated [______], 2021, is by and between TradeUP 88 Corp., a Cayman Islands exempted company (the
 “Company”), and VStock Transfer LLC, as warrant agent (in such capacity, 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 Ordinary Share and one-half of one Warrant (as defined below) (the “Units”) and, in connection
therewith, has determined to issue and deliver up to 5,060,000 redeemable warrants (including up to 660,000 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 Class A ordinary share of the Company, par value $0.0001 per share (“Ordinary Shares”),
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. [●], and a related prospectus (the “Prospectus”), for the registration, under the Securities
Act of 1933, as amended (the “Securities Act”), of the Units, the Warrants and the Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Share 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 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 Ordinary Shares 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 Ordinary Shares 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 completion of the first date on which the Company completes an
initial 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 Ordinary
Shares 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 Ordinary Share 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 Ordinary Shares and the
issuance of such Ordinary Shares, 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 Ordinary Shares equal to the quotient obtained by dividing (x) the product of the number of Ordinary Shares 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 Ordinary Shares 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


 


(d)            as
provided in Section 7.4 hereof.


 


3.3.2        Issuance
of Ordinary Shares 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 Ordinary Shares to which he, she or it is entitled,
registered in such name or names as may be directed by him, her or it on the register of members of the Company, 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 as to which
such Warrant shall not have been exercised. Notwithstanding the foregoing, the Company shall not be obligated to deliver any Ordinary
Shares 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 Ordinary Shares 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 Ordinary Shares upon exercise
of a Warrant unless the Ordinary Shares 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 Ordinary Shares. 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 an Ordinary Share, the Company shall round down to the nearest whole number, the number of
Ordinary Shares to be issued to such holder.


 


3.3.3        Valid
Issuance. All Ordinary Shares 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 Ordinary Shares is issued and who
is registered in the register of members of the Company shall for all purposes be deemed to have become the holder of record of such Ordinary
Shares 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 register of members 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 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% (or such other amount as a holder may specify) (the “Maximum Percentage”) of the Ordinary Shares outstanding
immediately after giving effect to such exercise. For purposes of the foregoing sentence, the aggregate number of Ordinary Shares beneficially
owned by such person and its affiliates shall include the number of Ordinary Shares issuable upon exercise of the Warrant with respect
to which the determination of such sentence is being made, but shall exclude Ordinary Shares 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 shares 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 Ordinary Shares,
the holder may rely on the number of outstanding Ordinary Shares 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 Ordinary Shares
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 Ordinary Shares then outstanding. In any case, the number of issued and
outstanding Ordinary Shares 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 Ordinary Shares 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        Sub-Divisions.
If after the date hereof, and subject to the provisions of Section 4.6 below, the number of issued and outstanding
Ordinary Shares is increased by a capitalization or share dividend paid in Ordinary Shares to all or substantially all holders of Ordinary
Shares, or by a split-up of Ordinary Shares or other similar event, then, on the effective date of such capitalization or share dividend,
split-up or similar event, the number of Ordinary Shares issuable on exercise of each Warrant shall be increased in proportion to such
increase in the issued and outstanding Ordinary Shares. A rights offering made to all or substantially all holders of Ordinary Shares
entitling holders to purchase Ordinary Shares at a price less than the “Historical Fair Market Value” (as defined below)
shall be deemed a share dividend of a number of Ordinary Shares equal to the product of (i) the number of Ordinary Shares 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 Ordinary Shares) multiplied by (ii) one (1) minus the quotient of (x) the price per Ordinary Share
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 Ordinary Shares, in determining the price payable
for Ordinary Shares, 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 Ordinary Shares during the ten (10) trading day period ending on the trading day prior to the first date on which the
Ordinary Shares trade on the applicable exchange or in the applicable market, regular way, without the right to receive such rights.
No Ordinary Shares 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 Ordinary Shares a dividend or make a distribution in cash, securities or other assets on account of such Ordinary Shares (or other
securities 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 Ordinary Shares in connection with
a proposed initial Business Combination, (d) to satisfy the redemption rights of the holders of the Ordinary Shares in connection
with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association  to affect the substance
or timing of the Company’s obligation to provide for the redemption of Class A ordinary shares 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 (e) 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 Ordinary Share 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares is decreased by a consolidation, combination, reverse share split or reclassification of Ordinary Shares
or other similar event, then, on the effective date of such consolidation, combination, reverse share split, reclassification or similar
event, the number of Ordinary Shares issuable on exercise of each Warrant shall be decreased in proportion to such decrease in issued
and outstanding Ordinary Shares.


 


4.3           Adjustments
in Exercise Price. Whenever the number of Ordinary Shares 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 Ordinary Shares
purchasable upon the exercise of the Warrants immediately prior to such adjustment, and (y) the denominator of which shall be the
number of Ordinary Shares 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
Ordinary Shares (other than a change covered by Section 4.1 or Section 4.2 hereof or that
solely affects the par value of such Ordinary Shares), 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 Ordinary Shares), 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 Ordinary Shares of the Company immediately theretofore purchasable
and receivable upon the exercise of the rights represented thereby, the kind and amount of Ordinary Shares 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 Ordinary Shares 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 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 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 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 Ordinary Shares 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 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 the Ordinary Shares 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 the Ordinary Shares 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 Shareholder. A Warrant does not entitle the Registered Holder thereof to any of the rights of a shareholder 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 shareholders in respect of the meetings of shareholders 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 Ordinary Shares. The Company shall at all times reserve and keep available a number of its authorized but unissued Ordinary Shares
that shall be sufficient to permit the exercise in full of all outstanding Warrants issued pursuant to this Agreement.


 






     


     


    

 


7.4           Registration
of Ordinary Shares; Cashless Exercise at Company’s Option.


 


7.4.1        Registration
of the Ordinary Shares. The Company agrees that as soon as practicable, but in no event later than twenty (20) 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares equal to the quotient obtained
by dividing (x) the product of the number of Ordinary Shares underlying the Warrants, multiplied by the excess of the “Fair
Market Value” (as defined below) less 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 Ordinary Shares 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
Ordinary Shares 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 Ordinary Shares are at the time of any exercise of a Warrant not listed on a national securities
exchange such that they satisfy 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 Ordinary Shares 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 Ordinary
Shares 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 Ordinary Shares 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 Ordinary Shares 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 Ordinary Shares to be issued pursuant to
this Agreement or any Warrant or as to whether any Ordinary Shares 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 Ordinary Shares 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 given when so delivered if by hand or overnight delivery or if sent by certified mail or private

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 for any such action, proceeding or claim. The Company hereby waives any objection to such exclusive
jurisdiction and that such courts represent an inconvenient forum. Notwithstanding the foregoing, the provisions of this paragraph will
not apply to suits brought to enforce 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.


 






     


     


    

 


9.4           Persons
Having Rights under this Agreement. Nothing in this Agreement shall be construed to confer upon, or give to, any person, corporation
or other entity other than the parties hereto and the Registered Holders of the Warrants any right, remedy, or claim under or by reason
of this Agreement or of any covenant, condition, stipulation, promise, or agreement hereof. All covenants, conditions, stipulations,
promises, and agreements contained in this Agreement shall be for the sole and exclusive benefit of the parties hereto and their successors
and assigns and of the Registered Holders 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 4.1.2 or (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 of the Registered Holders under this Agreement. All other modifications
or amendments, including any modification or amendment to increase the Warrant Price or shorten the Exercise Period, shall require the
vote or written consent of the Registered Holders of 50% of the then-outstanding Warrants. Notwithstanding the foregoing, the Company
may lower the Warrant Price or extend the duration of the Exercise Period pursuant to Sections 3.1 and 3.2,
respectively, without the consent of the Registered Holders.


 


9.9           Severability.
This Agreement shall be deemed 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

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 Class A ordinary
shares, $0.0001 par value (“Ordinary Shares”), of TradeUP 88 Corp., a Cayman Islands exempted company (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 Ordinary Shares 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 Ordinary Share. 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 an Ordinary Share, the Company shall,
upon exercise, round down to the nearest whole number the number of Ordinary Shares to be issued to the Warrant holder. The number of
Ordinary Shares 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 one Ordinary Share 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.


 






    B-1 


     


    

 


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.


 


Reference is hereby made to
the further provisions of this Warrant Certificate set forth on the reverse hereof and such further provisions shall for all purposes
have the same effect as though fully set forth at this place.


 


This Warrant Certificate shall
not be valid unless countersigned by the Warrant Agent, as such term is used in the Warrant Agreement. This Warrant Certificate shall
be governed by and construed in accordance with the internal laws of the State of New York.

[Form of Warrant Certificate]


 


[Reverse]


 


The Warrants evidenced by
this Warrant Certificate are part of a duly authorized issue of Warrants entitling the holder on exercise to receive [               ]
Ordinary Shares 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 New York 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 Ordinary Shares to be issued upon exercise is effective under the Securities Act and (ii) a
prospectus thereunder relating to the Ordinary Shares 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 Ordinary Shares 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 an Ordinary Share, the Company shall, upon exercise, round down to the nearest whole number of Ordinary Shares
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.


 






    B-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 shareholder of the Company.

Election to Purchase


 


(To Be Executed Upon Exercise of Warrant)


 


The undersigned hereby irrevocably
elects to exercise the right, represented by this Warrant Certificate, to receive [               ]
Ordinary Shares and herewith tenders payment for such Ordinary Shares to the order of TradeUP 88 Corp. (the “Company”)
in the amount of $[               ] in accordance with the
terms hereof. The undersigned requests that a certificate for such Ordinary Shares be registered in the name of [               ],
whose address is [               ] and that such Ordinary Shares
be delivered to [               ] whose address is [               ].
If said [               ] number of Ordinary Shares is less
than all of the Ordinary Shares purchasable hereunder, the undersigned requests that a new Warrant Certificate representing the remaining
balance of such Ordinary Shares be registered in the name of [               ],
whose address is [               ] and that such Warrant Certificate
be delivered to [               ], whose address is [               ].


 


In the event that the Warrant
is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number
of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with Section 7.4 of the
Warrant Agreement.


 


In the event that the Warrant
may be exercised, to the extent allowed by the Warrant Agreement, through cashless exercise (i) the number of Ordinary Shares that
this Warrant is exercisable for would be determined in accordance with the relevant section of the Warrant Agreement which allows for
such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably elects to exercise
the right, represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary
Shares. If said number of shares is less than all of the Ordinary Shares purchasable hereunder (after giving effect to the cashless exercise),
the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be registered in the
name of [               ], whose address is [               ]
and that such Warrant Certificate be delivered to [               ],
whose address is [               ].
