          1.   The Credit Agreement is hereby amended by deleting the

          hereof; (c) the execution and delivery hereof by Borrower and the
          performance and observance by Borrower of the provisions hereof

          agreement, instrument or document binding upon or enforceable

          Borrower in every respect, enforceable in accordance with its
          terms.

          will any occur immediately after the execution and delivery of
          this Amendment Agreement by the performance or observance of any
          provision hereof.

          11.  Each reference to the credit agreement that is made in the
          credit agreement or any other writing shall hereafter be

          governed by the laws of the State of Ohio.

          13.  This Amendment Agreement may be executed in any number of
          counterparts each of which, when so executed and delivered, shall
          be an original, but such counterparts shall together constitute
          one and the same instrument.  After execution of this Amendment
          Agreement by all the parties hereto, this Amendment Agreement
          shall be effective as of May 31, 1994.
