(1) Class A ordinary share for $11.50 per share (subject to adjustment). Each Warrant will become exercisable on the later of (i) 30 days after the Company’s completion of a merger, share exchange, asset acquisition, share purchase,
reorganization or other similar business combination (“Business Combination”) and (ii) 12 months from the closing of the Company’s initial public offering (“IPO”), and will expire unless exercised before 5:00 p.m., New York

Units represented by this certificate are not transferable separately prior to the 52nd day after the date of the prospectus relating to the Company’s IPO, subject to earlier separation in the discretion of Citigroup Global Markets Inc.
provided that the Company has filed with the Securities and Exchange Commission a Current Report on Form 8-K which includes an audited balance sheet reflecting the Company’s receipt of the gross proceeds
of the IPO and issued 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                , 2018, 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 Plaza, 30th Floor, New York, New
York 10004, and are available to any Warrant holder on written request and without cost. 
 This certificate is not valid unless
