Each Unit (“Unit”) consists of one (1) share of common stock, par value $.0001 per share (“Common Stock”), of STONE TAN CHINA ACQUISITION CORP., a Delaware corporation (the “Company”), and one warrant (the “Warrant”).

The Common Stock and Warrant comprising the Units represented by this certificate may trade separately on the 90th  day after the date of the prospectus unless the representative of the underwriters determines that an earlier date is acceptable; provided, however, in no event will the representative of the underwriters allow separate trading of the common stock and warrants until the Company files an audited balance sheet reflecting the Company’s receipt of the gross proceeds of the offering.  The terms of the Warrants are governed by a Warrant Agreement, dated as of               , 2007, 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 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.
