Credit  Agreement and all other documents,  instruments and agreements  executed
and/or  delivered in connection  therewith shall remain in full force and effect
and are hereby ratified and confirmed.
                  (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 Agent or the Banks, nor constitute a waiver of
any provision of the Credit  Agreement or any other  documents,  instruments and
