When the Registration Statement becomes effective under the Securities Act and the Warrants included in the Units have been delivered by the Company pursuant to the Underwriting Agreement against the payment of the consideration set forth in the Underwriting Agreement, assuming the due authorization, execution and delivery thereof by the Warrant Agent, the Warrants will constitute valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, subject to (i) applicable bankruptcy, insolvency, receivership, conservatorship, liquidation, reorganization, moratorium, fraudulent transfer and other laws affecting the enforcement of creditors’ rights generally and (ii) the application of general principles of equity (whether applied by a court of law in equity or at law).
