on the date that is five (5) years after the completion of the Company’s initial Business Combination (or, if an effective registration statement covering the Common Shares issuable upon exercise of the warrants is not then effective and a
prospectus relating to such Common Shares is not then available, upon such registration statement being effective and such prospectus being available for five consecutive business days), or earlier upon redemption or liquidation, in accordance with
the terms set forth in the Warrant Agreement (defined below). The Common Shares and Warrants comprising the Units represented by this certificate are not transferable separately prior to

with the U.S. Securities and Exchange Commission 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.
The terms of the Warrants are governed by a Warrant Agreement, dated as of                 , 2016, between the Company and Continental Stock Transfer & Trust
Company, as Warrant Agent (the “Warrant Agreement”), 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 17 Battery Place, New York, New York 10004, and are available to any Warrant holder on written request and without cost. 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.
