          consecutive  fiscal quarters to (ii) Consolidated  Interest Expense of
          the Borrower  and its  Subsidiaries  for such period,  to be less than

     5.   Representations   and  Warranties.   The  Borrower  hereby   confirms,
          reaffirms and restates the representations and warranties set forth in
          Section 10 of the Credit  Agreement;  provided that each  reference to
          the Credit Agreement  therein shall be deemed to be a reference to the
          Credit  Agreement after giving effect to this Amendment.  The Borrower
          represents  and  warrants no Default or Event of Default has  occurred
          and is continuing.

     6.   Continuing  Effect  of  Credit  Agreement.  This  Amendment  shall not
          constitute a waiver or amendment of any other  provision of the Credit
          Agreement not expressly  referred to herein and shall not be construed
          as a waiver or consent to any further or future  action on the part of
          the  Borrower   that  would   require  a  waiver  or  consent  of  the
          Administrative Agent or the Banks. Except as expressly amended hereby,

          force and effect.
