is the owner of
                                 Units. 

Each Unit (“Unit”) consists of one (1) share of common stock, par value $0.0001 per share (“Common Stock”), of Bellevue

business combination with one or more businesses or entities (a “Business Combination”), 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 prior to
            , 2022, unless Chardan Capital Markets LLC informs the Company of their 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             , 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 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. 

This certificate is not valid unless countersigned by the Transfer Agent and Registrar of the Company. This certificate shall be governed by and construed in
accordance with the internal laws of the State of New York. Witness the facsimile seal of the Company and the facsimile signatures of its duly authorized officers.
