Each
Unit (“Unit”) consists of one (1) share of Class A common stock, par value $0.0001 per share (“Class
A Common Stock”), of Panacea Acquisition Corp., a Delaware corporation (the “Company”),
and one-third (1/3) of one redeemable warrant (each whole warrant exercisable for one share of Class A common stock) (the “Warrant”).
Each whole Warrant entitles the holder to purchase one (1) share of Class A Common Stock (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 an initial 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

Business Combination, or earlier upon redemption or liquidation. The shares of Class A Common Stock and Warrants comprising the

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 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.

York, New York 10004, and are available to any Warrant holder on written request and without cost.
