the date of the prospectus relating to the Company’s initial public offering (or, if such date is not a business day, the following
business day), unless UBS Securities LLC informs us of its decision to allow earlier separate trading, subject to the Company’s
filing with the Securities and Exchange Commission of a Current Report on Form 8-K containing an audited balance sheet reflecting
the Company’s receipt of the gross proceeds of the offering and issuing a press release announcing when separate trading will begin.

Company, LLC 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
