(2) The Securities have been duly authorized, and, when executed and authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the underwriters pursuant to the Underwriting Agreement, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms; and
