2. Due Authorization. The undersigned, jointly and severally, represents and warrants to the Purchaser that this Joinder Agreement has been duly and validly authorized, executed and delivered by such Acquired Guarantor and constitutes a valid and binding obligation of such Acquired Guarantor, enforceable against such Acquired Guarantor, except that the enforcement thereof may be subject to the Enforceability Exceptions.
