 THIS CERTIFIES THAT

     Units. 
  
 Each Unit (“Unit”) consists of one (1) share of common stock, par value $0.001 per share (the “Common Stock”), of Sapphire Industrials Corp., a Delaware corporation (the
“Corporation”), and one warrant (the “Warrant”). Each Warrant entitles the holder to purchase one (1) share of Common Stock for $7.50 per share (subject to adjustment pursuant to the Warrant Agreement, as described below).
The Common Stock and the Warrant comprising the Units represented by this certificate are not transferable separately prior to
                         [the 35th day after the date of the registration statement] unless Citigroup Global Markets Inc. informs us of its decision to allow earlier separate trading, provided that in no event may the common
stock and warrants be traded separately until the Corporation has filed with the Securities and Exchange Commission a Current Report on Form 8-K which includes an audited balance sheet reflecting its receipt of the gross proceeds of the initial
public offering of the Units. The terms of the Warrants are governed by a Warrant Agreement, dated as of                     , between the
Corporation and Mellon Investor Services LLC (the “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 480 Washington Blvd., 29th Floor, Jersey City, NJ 07310 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 Corporation.
