and each, a “Warrant”) to purchase Class A ordinary shares, of $0.001 par value per share (“Ordinary
Shares”), of ITHAX Acquisition Corp., 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 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 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 Warrant 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, without regard to conflicts of laws principles
thereof.

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.

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

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.
