Each whole redeemable Warrant entitles the holder thereof to purchase one (1) share of Common Stock at a price of $11.50 per full share (subject to adjustment), upon the later to occur of (i) thirty (30) days after the Company’s completion of 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) eighteen (18) months from the closing of the Company’s initial public offering, and, unless exercised earlier, will expire at 5:00 p.m., New York City Time, on the date that is five (5) years after the date on which the Company completes its initial Business Combination, or earlier upon redemption thereof or the Company’s liquidation. The Common Stock and Warrants comprising the Units represented by this certificate are not transferable separately prior to the fifty-second (52^nd) day after the date of the prospectus relating to the Company’s initial public offering, unless EF Hutton, division of Benchmark Capital Markets LLC determines that an earlier date is acceptable, but in no event will the Common Stock 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 Common Stock and Warrant prior to the fifty-second (52^nd) day after the date of the prospectus.

The terms of the Warrants are governed by a warrant agreement (the “Warrant Agreement”), dated as of [●], 2021, between 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.
