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,
$0.0001 par value per share (“Ordinary Shares”), of AEI CapForce II Investment Corp (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 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 of the number of Ordinary Shares to
be issued to the 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 Ordinary Share for any Warrant is equal to $11.50 per whole 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 null and 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.

[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 (or successor warrant agent) (collectively, 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 designated office(s) 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 designated office(s) 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(s) 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 charges 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.
