          Credit Facilities shall terminate and all borrowings and other 
          obligations under them shall be due immediately, without notice, at 
          the Bank's option, whether or not the Bank has made demand.

          A.   The Borrower or any guarantor of any of the Credit Facilities, 
               the Notes or the Leases ("Guarantor") fails to pay when due any 
               amount payable under the Credit Facilities or under any 
               agreement or instrument evidencing debt to any creditor;

          B.   The Borrower or any Guarantor (a) fails to observe or perform 
               any other term of this agreement, the Notes or the Leases; 
               (b) makes any materially incorrect or misleading representation, 
               warranty, or certificate to the Bank; (c) makes any materially 
               incorrect or misleading representation in any financial 
               statement or other information delivered to the Bank; or 
               (d) defaults under the terms of any agreement or instrument 
               relating to any debt for borrowed money (other than borrowings 
               under the Credit Facilities) such that the creditor declares the 
               debt due before its maturity;

          C.   There is a default under the terms of any loan agreement, 
               mortgage, security agreement or any other document executed as 
               part of the Credit Facilities, or any guaranty of the 
               obligations under the Credit Facilities becomes unenforceable in 
               whole or in part, or any Guarantor fails to promptly perform 
               under its guaranty;

          D.   A "reportable event" (as defined in the Employee Retirement 
               Income Security Act of 1974 as amended) occurs that would permit 
               the Pension Benefit Guaranty Corporation to terminate any 
               employee benefit plan of the Borrower or any affiliate of the 
               Borrower;

          E.   The Borrower or any Guarantor becomes insolvent or unable to pay 
               its debts as they become due;

            F.  The Borrower or any Guarantor (a) makes an assignment for the
                benefit of creditors; (b) consents to the appointment of a
                custodian, receiver or trustee for it or for a substantial part
                of its assets; or (c) commences any proceeding under any
                bankruptcy, reorganization, liquidation or similar laws of any
                jurisdiction; 

            G.  A custodian, receiver or trustee is appointed for the Borrower
                or any Guarantor or for a substantial part of its assets without
                its consent and is not removed within 60 days after such
                appointment; 

            H.  Proceedings are commenced against the Borrower or any Guarantor
                under any bankruptcy, reorganization, liquidation, or similar
                laws of any jurisdiction, and such proceedings remain
                undismissed for 60 days after commencement; or the Borrower or
                Guarantor consents to the commencement of such proceedings; 

            I.  Any judgment is entered against the Borrower or any Guarantor,
                or any attachment, levy or garnishment is issued against any
                property of the Borrower or any Guarantor; 

            J.  The Borrower or any Guarantor dies; 

            K.  The Borrower or any Guarantor, without the Bank's written
                consent, (a) is dissolved, (b) merges or consolidates with any
                third party, (c) leases, sells or otherwise conveys a material
                part of its assets or business outside the ordinary course of
                business, (d) leases, purchases, or otherwise acquires a
                material part of the assets of any other corporation or business
                entity, except in the ordinary course of business, or (e) agrees
                to do any of the foregoing, (notwithstanding the foregoing, any
                subsidiary may merge or consolidate with any other subsidiary,
                or with the Borrower, so long as the Borrower is the survivor); 

            L.  The loan-to-value ratio of any pledged securities at any time
                exceeds N/A%, and such excess continues for five (5) days
                after notice from the Bank to the Borrower; 

            M.  There is a substantial change in the existing or prospective
                financial condition of the Borrower or any Guarantor which the
                Bank in good faith determines to be materially adverse; or 

            N.  The Bank in good faith shall deem itself insecure. 

      11.2  REMEDIES.  If the borrowings and all other obligations under the
            Credit Facilities are not paid at maturity, whether by demand,
            acceleration or otherwise, the Bank shall have all of the rights and
            remedies provided by any law or agreement. Any requirement of
            reasonable notice shall be met if the Bank sends the notice to the
            Borrower at least seven (7) days prior to the date of sale,
            disposition or other event giving rise to the required notice. The
            Bank is authorized to cause all or any part of the Collateral to be
            transferred to or registered in its name or in the name of any other
            person, firm or corporation, with or without designation of the
            capacity of such nominee. The Borrower shall be liable for any
            deficiency remaining after disposition of any Collateral. The
            Borrower is liable to the Bank for all reasonable costs and expenses
            of every kind incurred in the making or collection of the Credit
            Facilities, including, without limitation, reasonable attorney's
            fees and court costs (whether attributable to the Bank's in-house or
            outside counsel). These costs and expenses shall include, without
            limitation, any costs or expenses incurred by the Bank in any
            bankruptcy, reorganization, insolvency or other similar proceeding. 

12.0  MISCELLANEOUS.

      12.1  Notice from one party to another relating to this agreement shall be
            deemed effective if made in writing (including telecommunications)
            and delivered to the recipient's address, telex number or fax number
            set forth under its name below by any of the following means: (a)
            hand delivery, (b) registered or certified mail, postage prepaid,
            with return receipt requested, (c) first class or express mail,
            postage prepaid, (d) Federal Express, or like overnight courier
            service or (e) fax, telex or other wire transmission with request
            for assurance of receipt in a manner typical with respect to
            communication of that type. Notice made in accordance with this
            section shall be deemed delivered upon receipt if delivered by hand
            or wire transmission, 3 business days after mailing if mailed by
            first class, registered or certified mail, or one business day after
            mailing or deposit with an overnight courier service if delivered by
            express mail or overnight courier. 

      12.2  No delay on the part of the Bank in the exercise of any right or
            remedy shall operate as a waiver. No single or partial exercise by
            the Bank of any right or remedy shall preclude any other future
            exercise of it or the exercise of any other right or remedy. No
            waiver or indulgence by the Bank of any default shall be effective
            unless in writing and signed by the Bank, nor shall a waiver on one
            occasion be construed as a bar to or waiver of that right on any
            future occasion.
