THIS CERTIFIES THAT ______________________________________________________________


 


is the owner of _____________________________________________________________________
Units.



 








Each Unit (“Unit”) consists of one
Class A ordinary share (“Ordinary Share”), with a par value $0.0001 per share, of Bombax Healthcare Acquisition Corporation,
a Cayman Islands company (the “Company”), one-half of one redeemable warrant (“Warrant”). Each whole redeemable
Warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per full share (subject to adjustment).
Each warrant will become exercisable upon completion of an initial business combination, and will expire on the fifth anniversary of the
completion of an initial business combination, or earlier upon redemption or liquidation. The ordinary shares and Warrants comprising
the Units represented by this certificate are not transferable separately prior to the fifty-second (52nd) day after the date
of the prospectus relating to the Company’s initial public offering, unless JonesTrading Institutional Services LLC determines that
an earlier date is acceptable, but in no event will the Ordinary Shares and Warrants be traded separately until the Company files with
the Securities and Exchange Commission (the “SEC”) a current report on Form 8-K which includes an audited balance sheet reflecting
the receipt by the Company of the gross proceeds from its initial public offering including the proceeds received by the Company from
the exercise of the over-allotment option thereto, if the over-allotment option is exercised. If the over-allotment option is exercised
after the date of the prospectus, we will file an amendment to the Form 8-K or a new Form 8-K to provide updated financial information
to reflect the exercise of the over-allotment option. We will also include in the Form 8-K, or amendment thereto, or in a subsequent Form
8-K, information indicating if the underwriters has allowed separate trading of the Ordinary Shares and Warrants prior to the fifty-second
(52nd) day after the date of the prospectus.


 


The terms of the Warrants are governed by a
warrant agreement (the “Warrant Agreement”), dated as of [●], 2021between the Company and Continental Stock Transfer
& Trust Company, as the warrant agent, and are subject to the terms and provisions contained therein, all of which terms and provisions
the holder of this certificate consents to by acceptance hereof. Copies of the Warrant Agreement is on file at the office of Continental
Stock Transfer & Trust Company at 1 State Street, 30th Floor, New York, NY 10004, and is available to any Warrant Holder on written
request and without cost.


 


This certificate is not valid unless countersigned
by the Transfer Agent and Registrar of the Company.

This Unit 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.
