CONSISTING OF ONE CLASS A ORDINARY SHARE AND ONE-HALF OF ONE 

REDEEMABLE WARRANT TO PURCHASE ONE CLASS A ORDINARY SHARE

 

THIS
CERTIFIES THAT                 is the owner of                
Units.

 

Each
Unit (“Unit”) consists of one (1) Class A ordinary share, par value $0.0001 per share (“Ordinary Shares”),
of TradeUP 88 Corp., a Cayman Islands exempted company (the “Company”), and one-half (1/2) of one redeemable warrant
(each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one (1) Ordinary Share for $11.50
per share (subject to adjustment). Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s
completion of a merger, share exchange, asset acquisition, share purchase, reorganization or other similar business combination
with one or more businesses (each, a “Business Combination”), and (ii) twelve (12) months from the closing of the
Company’s initial public offering, and will expire unless exercised before 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, or earlier upon redemption or
liquidation (the “Expiration Date”). The Ordinary Shares and Warrants comprising the Units represented by this certificate
are not transferable separately prior to           , 2021, unless US Tiger Securities,
Inc. elects to allow earlier separate trading, subject to the Company’s filing with the Securities and Exchange Commission
of a Current Report on Form 8-K containing an audited balance sheet reflecting the Company’s receipt of the gross proceeds
of the initial public offering and issuing a press release announcing when separate trading will begin. No fractional warrants
will be issued upon separation of the Units and only whole warrants are exercisable. The terms of the Warrants are governed by
a Warrant Agreement, dated as of           , 2021, between the Company and vStock
Transfer LLC, as Warrant Agent, and are subject to the terms and provisions contained therein, all of which terms and provisions
the holder of this certificate consents to by acceptance hereof. Copies of the Warrant Agreement are on file at the office of
the Warrant Agent at 18 Lafayette Place, Woodmere, New York 11598, and are available to any Warrant holder on written request
and without cost.

 

Upon
the consummation of the Business Combination, the Units represented by this certificate will automatically separate into the Class
A Ordinary Shares and Warrants comprising such Units.

 

This
certificate is not valid unless countersigned by the Transfer Agent and Registrar of the Company.

 

This
certificate shall be governed by and construed in accordance with the internal laws of the State of New York.
