CUSIP [•]


 


Warrant Certificate


 


This Warrant Certificate certifies that
___________________, or registered assigns, is the registered holder of _____________ warrants (the “Warrants”)
to purchase Class A Ordinary Shares, $0.0001 par value, or Class C Ordinary Shares, $0.0001 par value, as applicable (collectively,
the “Ordinary Shares”), of One Madison Corporation, 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 (each, a “Warrant”) 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
the 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 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.


 


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 and
construed in accordance with the internal laws of the State of New York, without regard to conflicts of laws principles thereof.

[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 ___________ (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 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 Class A Ordinary Shares issuable upon exercise of the Warrants is effective under the Securities Act and (ii) a prospectus
relating thereto is current, except through “cashless exercise” as provided for in the Warrant Agreement. Further,
no Warrant may be exercised unless the Ordinary Shares issuable upon such Warrant exercise have been registered, qualified or deemed
to be exempt under the securities laws of the state of residence of the Registered Holder of the Warrants.


 


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.
