Warrant Certificate


 


This Warrant Certificate
certifies that         , or registered assigns, is the registered holder of       
warrants evidenced hereby (the “Warrants” and each, a “Warrant”) to purchase Class A Ordinary
Shares, $0.0001 par value per share (the “Ordinary Shares”), of Alpha Partners Technology Merger Corp., a Cayman
Islands exempted company (the “Company”). Each whole Warrant entitles the holder, upon exercise during the Exercise
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 “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 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 Warrant
Price per Ordinary Share for any Warrant is equal to $11.50 per share. The Warrant 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.


 


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 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 Ordinary Shares to be issued upon exercise is effective under the Securities Act of 1933, as amended, 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 the 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.

of the Warrant Agreement, the number of Ordinary Shares that this Warrant is exercisable for shall be determined in accordance

Warrant is to be exercised on a “cashless” basis pursuant to Section 7.4 of the Warrant Agreement, the number

which allows for such cashless exercise and (ii) the holder hereof shall complete the following: The undersigned hereby irrevocably

of such Ordinary Shares be registered in the name of              ,
