               Units.

 

Each Unit (“Unit”) consists of one (1) share of
Class A common stock, par value $0.0001 per share (“Common Stock”), of Accelerate Acquisition Corp., a Delaware corporation
(the “Company”), and one-third (1/3) of one redeemable warrant (each whole warrant, a “Warrant”). Each
whole Warrant entitles the holder to purchase one (1) share (subject to adjustment) of Common Stock for $11.50 per share (subject
to adjustment). Each Warrant will become exercisable on the later of (i) thirty (30) days after the Company’s completion
of a merger, capital stock exchange, asset acquisition, stock 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 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 or liquidation (the
“Expiration Date”). The Common Stock and Warrants comprising the Units represented by this certificate are not transferable
separately prior to [●], 2021, unless UBS Securities LLC elects 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 initial 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 [●], 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 hereof. Copies of the Warrant Agreement are on file at
the office of the Warrant Agent at 1 State Street, 30th Floor, New York, New York 10004, and are available to any Warrant holder
on written request and without cost.

 

This certificate shall be governed by and construed in accordance
with the internal laws of the State of New York.
