WARRANT

 

THIS WARRANT CERTIFIES
THAT, for value received                                         ,
or registered agents, is the registered holder of a Warrant or Warrants (the “Warrant”), expiring on a date which is five
(5) years from the completion of the Company’s initial business combination, to purchase one fully paid and non-assessable Class
A ordinary share (the “Warrant Shares”), with a par value $0.0001 per share, of Bombax Healthcare Acquisition Corporation,
a Cayman Islands company (the “Company”), for each whole Warrant evidenced by this Warrant Certificate. This Warrant Certificate
is subject to and shall be interpreted under the terms and conditions of the Warrant Agreement (as defined below).

 

No
fractional Warrants will be issued upon separation of the units and only whole Warrants will trade. The Company will not issue fractional
shares and Warrants may be exercised only for a whole number of shares. If, upon the exercise of Warrant, a holder would be entitled to
receive a fractional interest in a share, the Company will, upon exercise, round down to the nearest whole number of the number of shares
of Warrant Share to be issued to the holder. The number of shares of Warrant Share issuable upon exercise of the Warrants is subject to
adjustment upon the occurrence of certain events set forth in the Warrant Agreement.

 

The
Warrant entitles the holder thereof to purchase from the Company, from time to time, in whole or in part, after the completion of the
Company’s initial business combination, such number of Warrant Shares at the price of $11.50 per full share (the “Warrant
Price”), upon surrender of this Warrant Certificate and payment of the Warrant Price at the office or agency of Continental Stock
Transfer & Trust Company (the “Warrant Agent”), such payment to be made subject to the conditions set forth herein and
in the Warrant Agreement, dated [●], 2021, between the Company and the Warrant Agent (the “Warrant Agreement”). The
Warrants may be exercised on cashless basis as set forth in the Warrant Agreement and such exercise is exempt from registration under
the Securities Act of 1933, as amended. The Warrant Agreement provides that, upon the occurrence of certain events, the Warrant Price
and the number of Warrant Shares purchasable hereunder, set forth on the face hereof, may be adjusted, subject to certain conditions.
The term Warrant Price as used in this Warrant Certificate refers to the price per full Warrant Share at which Warrant Shares may be purchased
at the time the Warrant is exercised.

 

This
Warrant will expire on the date first referenced above if it is not exercised prior to such date by the registered holder pursuant to
the terms of the Warrant Agreement or if it is not redeemed by the Company prior to such date.

 

Upon
any exercise of the Warrant for less than the total number of full Warrant Shares provided for herein, there shall be issued to the registered
holder(s) hereof or its assignee(s) a new Warrant Certificate covering the number of Warrant Shares for which the Warrant has not been
exercised.

 

     

     

    

 

Warrant
Certificates, when surrendered at the office or agency of the Warrant Agent by the registered holder(s) hereof in person or by 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 and evidencing in the aggregate a
like number of Warrants.

 

Upon
due presentment for registration of transfer of the Warrant Certificate at the office or agency 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 applicable
tax or other governmental charge.

 

The
Company and the Warrant Agent may deem and treat the registered holder(s) 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 registered
holder(s), and for all other purposes, and neither the Company nor the Warrant Agent shall be affected by any notice to the contrary.

 

This
Warrant does not entitle the registered holder(s) to any of the rights of a shareholder of the Company.

 

The
Company reserves the right to call the Warrant at any time prior to its exercise with a notice of call in writing to the holders of record
of the Warrant, giving at least 30 days’ notice of such call, at any time while the Warrant is exercisable, if the last sale price
of the Shares has been at least $23.00 per share (the “Redemption Trigger Price”) on each of 20 trading days within any 30
trading day period (the “30-day trading period”) ending on the third business day prior to the date on which notice of such
call is given and if, and only if, there is a current registration statement in effect with respect to the Shares underlying the Warrants
for the entire 30-day trading period and continuing each day thereafter until the date of redemption. The call price of the Warrants is
to be $0.01 per Warrant. Any Warrant either not exercised or tendered back to the Company by the end of the date specified in the notice
of call shall be canceled on the books of the Company and have no further value except for the $0.01 call price.
