Each

Ordinary Shares”), of NextGen Acquisition Corp. II, a Cayman Islands exempted company (the “Company”),
and one-fifth (1/5) of one redeemable warrant (the “Warrant”). Each whole Warrant entitles the holder
to purchase one (1) Class A Ordinary Share (subject to adjustment) for $11.50 per share (subject to adjustment). Only whole Warrants
are exercisable. 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

separate trading earlier, subject to the Company’s filing of a Current Report on Form 8-K with the Securities and Exchange
Commission containing an audited balance sheet reflecting the Company’s receipt of the gross proceeds of its 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. 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 One State Street, 30th Floor, New York, New York 10004, and are available to any Warrant
holder on written request and without cost.
