Each
Unit (“Unit”) consists of one (1) share of Class A common stock, par value $0.0001 per share (“Common
Stock”), of Siddhi Acquisition Corp., a Delaware corporation (the “Company”), and one-third of one
warrant (“Warrant”). Each whole Warrant entitles the holder to purchase one share of Common Stock for $11.50
per share (subject to adjustment). Each whole Warrant will become exercisable on the later of (i) thirty days after the Company’s
completion of an initial merger, capital stock exchange, asset acquisition, or other similar business combination with one or
more businesses or entities (a “Business Combination”) and (ii) 12 months from the closing of the Company’s
initial public offering (“IPO”), and will expire unless exercised before 5:00 p.m., New York City Time, on
the fifth anniversary of the completion of an initial Business Combination, or earlier upon redemption or liquidation. The Common
Stock and Warrant(s) comprising the Unit(s) represented by this certificate are not transferable separately until fifty-two days
following the IPO, unless Credit Suisse Securities (USA) LLC informs the Company of its decision to allow earlier separate trading,
except that in no event will the Common Stock and Warrants be separately tradeable until the Company has filed an audited balance
sheet reflecting the Company’s receipt of the gross proceeds of its initial public offering and issued a press release announcing
when such separate trading will begin. The terms of the Warrants are governed by a Warrant Agreement, dated as of __________ __,
2021, 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 the Warrant Agent at 1 State Street, 30th Floor, New York,
New York 10004, and are available to any Warrant holder on written request and without cost.
