UNITS CONSISTING OF ONE CLASS A ORDINARY SHARE AND ONE-THIRD OF ONE REDEEMABLE 

WARRANT TO PURCHASE ONE CLASS A ORDINARY SHARE 

THIS CERTIFIES THAT                is the owner
of                Units. 
 Each Unit (“Unit”) consists of one
(1) Class A ordinary share, par value $0.0001 per share (“Ordinary Shares”), of Arctos NorthStar Acquisition Corp., a Cayman Islands exempted company (the “Company”), and
one-third (1/3) of one redeemable warrant (each whole warrant, a “Warrant”). Each Warrant entitles the holder to purchase one (1) Ordinary Share 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, 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 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 Ordinary Shares and Warrants comprising the Units represented by this
certificate are not transferable separately prior to                , 2021, unless Citigroup Global Markets Inc. 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 warrant are exerciseable. 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. 
 Upon the consummation of the Business Combination, the
Units represented by this certificate will automatically separate into the Class A Ordinary Shares and Warrants comprising such Units. 
 This
certificate is not valid unless countersigned by the Transfer Agent and Registrar of the Company. 
 This certificate shall be governed by and construed in
accordance with the internal laws of the State of New York. 
 Witness the facsimile signatures of its duly authorized officers.
