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 Class A common stock, $0.0001 par value (“Class A Common Stock”), of AdMY Technology
Group, Inc., 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 Class A Common Stock as set forth below, at the exercise price (the “Warrant 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 Warrant 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 Class A Common Stock. 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 of Class A Common Stock, the Company shall, upon
exercise, round down to the nearest whole number the number of shares of Class A Common Stock to be issued to the Warrant holder.
The number of shares of Class A 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 Warrant Price per share of Class A Common Stock for
any Warrant is equal to $11.50 per share. The Warrant 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 [ ] shares of Class A 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 Continental Stock Transfer & Trust Company, a New York corporation, 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 Warrant
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 Class A Common Stock to be issued upon exercise is effective under the Securities Act and (ii) a prospectus thereunder relating
to the shares of Class A 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 Class A 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 Class A Common Stock, the Company shall, upon exercise, round down to the nearest whole number of shares of Class A
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.

 

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 stockholder of the Company.
