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 Global Corporation, 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.

 

     

     

    

 

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.

 

     

     

    

 

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 Global Corporation (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
has been called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof
elects to exercise its Warrant pursuant to a Make-Whole Exercise, the number of Ordinary Shares that this Warrant is exercisable for shall
be determined in accordance with Section 6.2 of the Warrant Agreement. 

 

In the event that the Warrant
is a Private Placement Warrant that is to be exercised on a “cashless” basis pursuant to subsection 3.3.1(b) of
the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection
3.3.1(b) of the Warrant Agreement.

 

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 [               ].
