(30) days after the Company’s completion of a merger, capital stock exchange, asset acquisition, stock purchase, reorganization

public offering and issuing a press release announcing when separate trading will begin. No fractional warrants will be issued
upon separation of the Units and only whole Warrants will trade. The terms of the Warrants are governed by a Warrant Agreement,
dated as of __________, 2020, 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
