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               ,
