THIS CERTIFIES THAT                is the owner of              Units.

 

Each Unit (“Unit”) consists of one
(1) share of Class A common stock, par value $0.0001 per share (“Class A Common Stock”), of Crucible
Acquisition Corporation, 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 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 shares of Class A Common Stock and Warrants comprising the Units represented
by this certificate are not transferable separately prior to             , 2020, unless Credit Suisse Securities (USA) LLC elects to allow
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 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. 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.

 

Upon the consummation of the Business Combination,
the Units represented by this certificate will automatically separate into the Class A Common Stock 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.
