Each Unit (“Unit”) consists of one share of Class

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

reorganization or other similar business combination with one or more businesses or entities (a “Business Combination”) or
(ii) one year from the closing of the Company’s initial public offering. 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, LLC (“EF

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 [___], 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
