other  Loan  Document  or in any  document  furnished  at any  time  under or in

representations  and warranties  specifically refer to an earlier date, in which
case they shall be true and correct as of such  earlier  date and (B) the making

                  (c)  The  execution,   delivery  and   effectiveness  of  this
Amendment shall not, except as expressly provided herein, operate as a waiver of
any right, power or remedy of the Lenders,  the  Administrative  Agent under the
Credit Agreement, nor constitute a waiver or amendment of any other provision of
the Credit Agreement or for any purpose except as expressly set forth herein.
