                           (b) prejudice any right or remedy that any Agent or
         any Lender may now have (except to the extent such right or remedy was
         based upon existing defaults that will not exist after giving effect to
         the waiver granted above) or may have in the future under or in
         connection with the Credit Agreement or any other instrument or
         agreement referred to therein.

SECTION III.      CONDITIONS PRECEDENT TO EFFECTIVENESS
