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 Class A ordinary shares, $0.0001 par value (“Ordinary
Shares”), of one, a Cayman Islands exempted company (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 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. 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 an Ordinary
Share, the Company shall, 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 as set forth in the Warrant Agreement.


 


The initial
Exercise Price per one 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 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 [           ] Ordinary Shares
and are issued or to be issued pursuant to a Warrant Agreement dated as of [●], 2020 (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 issuance of 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.


 






     


     


    

 


Election to Purchase


 


(To Be Executed Upon Exercise of Warrant)


 


The undersigned hereby irrevocably elects
to exercise the right, represented by this Warrant Certificate, to receive [            ] Ordinary Shares and herewith tenders payment
for such Ordinary Shares to the order of one (the “Company”) in the amount of $[            ] in accordance with the terms
hereof. The undersigned requests that a certificate for such Ordinary Shares be registered in the name of [            ], whose address
is [            ] and that such Ordinary Shares be delivered to [            ] whose address is [            ]. If said [            ] number of Ordinary Shares
is less than all of the Ordinary Shares purchasable hereunder, the undersigned requests that a new Warrant Certificate representing
the remaining balance of such Ordinary Shares be registered in the name of [            ], whose address is [            ] and that such Warrant
Certificate be delivered to [            ], whose address is [            ].


 


In the event that the Warrant has been
called for redemption by the Company pursuant to Section 6.2 of the Warrant Agreement and a holder thereof elects to exercise its
Warrant pursuant to a Make-Whole Exercise, the number of Ordinary Shares that this Warrant is exercisable for shall be determined
in accordance with subsection 3.3.1(c) or Section 6.2 of the Warrant Agreement, as applicable.


 


In the event that the Warrant is a Private
Placement 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 right,
represented by this Warrant Certificate, through the cashless exercise provisions of the Warrant Agreement, to receive Ordinary
Shares. If said number of shares is less than all of the Ordinary Shares purchasable hereunder (after giving effect to the cashless
exercise), the undersigned requests that a new Warrant Certificate representing the remaining balance of such Ordinary Shares be
registered in the name of [            ], whose address is [            ] and that such Warrant Certificate be delivered to [            ], whose address
is [            ].
