hereby represents and warrants to the Administrative Agent and the Lenders, as
follows:

                  (a)      After giving effect to this Second Amendment, the
         representations and warranties set forth in Article V of the Amended
         Credit Agreement, and in each other Loan Document, are true and correct
         in all material respects on and as of the date
<PAGE>

         hereof and on and as of the Second Amendment Effective Date (as defined
         below) with the same effect as if made on and as of the date hereof,
         except to the extent such representations and warranties expressly
         relate solely to an earlier date, in which case they shall be true and
         correct in all material respects as of such earlier date.

                  (b)      After giving effect to this Second Amendment, the

         Borrower of this Second Amendment have been duly authorized by the
         Borrower.

         any such Person's Organization Documents; (ii) conflict with or result
         in any breach or contravention of, or the creation of any Lien under,
         (A) any Contractual Obligation to which the Borrower is a party, except

         Authority or any arbitral award to which the Borrower or its property
         is subject; or (iii) violate any material Law.

         arbitration or before any Governmental Authority by or against the
         Borrower or any of its Subsidiaries or against any of their properties
         or revenues that (i) purport to affect or pertain to this Amended
         Credit Agreement or any other Loan Document, or any of the transactions
