Each Unit (“Unit”) consists of one (1) Class A ordinary
share, par value $0.0001 per share (“Ordinary Shares”), of European Biotech 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
Credit Suisse Securities (USA) LLC and Kempen & Co. U.S.A., Inc. elect 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.

In each case, as more fully described in the
Company’s final prospectus dated [●], 2021, the holder(s) of this certificate shall be entitled to receive a
pro-rata portion of certain funds held in the trust account established in connection with the Company’s initial public
offering only in the event that (i) the Company redeems the Ordinary Shares sold in its initial public offering and
liquidates because it does not consummate an initial business combination within the period of time set forth in the
Company’s amended and restated memorandum and articles of association, as the same may be amended from time to time,
(ii) the Company redeems the Ordinary Shares sold in its initial public offering in connection with a shareholder vote to
amend the Company’s amended and restated memorandum and articles of association (A) that would modify the substance or
timing of the Company’s obligation to provide holders of the Ordinary Shares the right to have their shares redeemed in
connection with the Company’s initial business combination or to redeem 100% of the Ordinary Shares if the Company does
not complete its initial business combination within the time period set forth therein or (B) with respect to any other
provision relating to the rights of holders of the Ordinary Shares, or (iii) if the holder(s) seek(s) to redeem for cash his,
her or its respective Ordinary Shares in connection with a tender offer (or proxy solicitation, solely in the event the
Company seeks shareholder approval of the proposed initial business combination) setting forth the details of a proposed
initial business combination. In no other circumstances shall the holder(s) have any right or interest of any kind in or to
the trust account.
