UNITS
CONSISTING OF ONE SHARE OF CLASS A COMMON STOCK AND ONE-HALF OF ONE WARRANT

 

THIS
CERTIFIES THAT _______________________________________________________________

 

is
the owner of ______________________________________________________________________Units.

 

Each
Unit (“Unit”) consists of one share of Class A common stock, with a par value $0.0001 per share (“Class A Common Stock”),
of DUET Acquisition Corp., a Delaware corporation (the “Company”), and one-half of one redeemable warrant (“Warrant”).
Each redeemable Warrant entitles the holder thereof to purchase one share of Class A Common Stock at a price of $11.50 per full share
(subject to adjustment), upon the later to occur of (i) the date upon which the Company completes a merger, share exchange, asset acquisition,
share purchase, recapitalization, reorganization or other similar business combination with one or more businesses or entities (a “Business
Combination”) or (ii) one year from the effective date of the Company’s registration statement on Form S-1, as initially
filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 3, 2021, as amended. The shares of Class A
Common Stock 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 EF Hutton, division of Benchmark
Investments, Inc. (“EF Hutton”) determines that an earlier date is acceptable, but in no event will the shares of Class A
Common Stock and Warrants be traded separately until the Company files with 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 shares of Class A Common
Stock and Warrants prior to the 52nd day after the date of the prospectus.

 

The
terms of the Warrants are governed by a Warrant Agreement, dated as of [         ] 2022, between the Company and Continental Stock Transfer &
Trust Company, as 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 are on file at the office of Continental
Stock Transfer & Trust Company at 1 State Street, 30th Floor, New York, New York 10004, and are 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.
