(c)Default. The Guarantor is not in default of any provision under any material agreement, instrument, decree or order to which it is a party or by which its property is bound or affected that could result in a material adverse effect on the condition (financial or otherwise), properties or assets of the Guarantor.

(d)Consents. No consent, approval, order or authorization of, or registration, declaration or filing with, or notice to, any governmental authority or any third party is required in connection with the execution and delivery of this Guaranty or any of the agreements or instruments herein mentioned to which the Guarantor is a party or the carrying out or performance of any of the transactions required or contemplated hereby or thereby or, if required, such consent, approval, order or authorization has been obtained or such registration, declaration or filing has been accomplished or such notice has been given prior to the date hereof.
