Warrant Certificate

 

This Warrant Certificate certifies that                    ,
or registered assigns, is the registered holder of warrant(s) evidenced hereby (the “Warrants” and
each, a “Warrant”) to purchase Class A ordinary shares, $0.001 par value per share (“Ordinary
Shares”), of Yunhong International, a Cayman Islands exempted company (the “Company”). Each
whole 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 non-assessable 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. No fractional shares will 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 will,
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 set forth
in the Warrant Agreement.

 

The initial Exercise Price per share of
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 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.

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                 ,
2019 (the “Warrant Agreement”), duly executed and delivered by the Company to American
Stock Transfer & Trust Company, LLC, a New York limited liability trust 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. Capitalized 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 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.

Ordinary Shares that this Warrant is exercisable for shall be determined in accordance with subsection 3.3.1(b) and Section 6.4 of
the Warrant Agreement.

 

In the event that the Warrant is a Private
Placement Warrant, a Working Capital Warrant, a Representative Warrants or a Post-IPO Warrant that is to be exercised on a “cashless”
basis pursuant to subsection 3.3.1(c) 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(c) 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

Shares be registered in the name of                 ,
whose address is                         
and that such Warrant Certificate be delivered to                 ,
whose address is                 .
