Each Unit (“Unit”) consists
of one (1) share of common stock, par value $0.0001 per share (“Common Stock”), of Opes Acquisition Corp., a

on the later of (i) 30 days after the Company’s completion of an initial merger, capital stock exchange, asset acquisition,
or other similar business combination with one or more businesses or entities (a “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 City Time, on the fifth anniversary of the completion of an initial Business Combination,
or earlier upon redemption or liquidation. The Common Stock and Warrant(s) comprising the Unit(s) represented by this certificate
are not transferable separately until ninety days following the IPO, unless the underwriters inform the Company of their decision
to allow earlier separate trading, except that in no event will the Common Stock and Warrants be separately tradeable until the
Company has filed an audited balance sheet reflecting the Company’s receipt of the gross proceeds of its initial public offering
and issued a press release announcing when such separate trading will begin. 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 1 State Street
Plaza, New York, New York 10004, and are available to any Warrant holder on written request and without cost.
