knowledge that Administrative Agent and Lenders are relying on the following
representations and warranties in executing this Amendment, as follows:

                  (a) Each Obligor has the organizational power and authority to
         execute, deliver and perform this Amendment and such other Loan
         Documents executed in connection herewith, and all organizational
         action on the part of such Person requisite for the due execution,

         Original Agreement and this Amendment.

                  (d) Execution, delivery and performance of this Amendment by

         political subdivision of the United States of America or any state
         thereof.

                  (e) No Default or Event of Default exists and all of the

         date other than those which have been disclosed to Administrative Agent
         and Lenders in writing.

         SECTION 7. Extent of Amendments. Except as otherwise expressly provided
herein, the Original Agreement and the other Loan Documents are not amended,
