exercisable on the later of (i) thirty (30) days after the Company’s completion of a merger, share exchange, asset acquisition,
share purchase, reorganization or other similar business combination with one or more businesses (each, a “Business Combination”),
and (ii) twelve (12) months from the closing of the Company’s initial public offering, and will expire unless exercised before 5:00

issued upon separation of the Units and only whole warrants are exercisable. The terms of the Warrants are governed by a Warrant Agreement,
dated as of           , 2021, between the Company and vStock Transfer LLC, as Warrant
Agent, and are subject to the terms and provisions contained therein, all of which terms and provisions the holder of this certificate
