                     (i)    The CareStream Transactions are correctly described
              in paragraph (a) above and the memoranda dated October 3, 1995
              and October 13, 1995 (collectively, the "Transaction
              Description"), from Borrower to Lenders.  The Transaction
              Description does not omit any statement of a material fact
              necessary to make the statements contained therein or herein not
              misleading.

                     (ii)   The principal amount of the CareStream Note will be
              not less than the actual amount of all loans, advances, capital
              contributions and other investments made by Borrower and its
              Consolidated Subsidiaries in the CareStream Operations after
              March 31, 1993, less $5,000,000.  After giving effect to the
              CareStream Transactions, (A) the maximum aggregate amount of (1)
              obligations of Borrower and the Consolidated Subsidiaries to pay
              the deferred or contingent purchase prices for the CareStream
              Operations and (2) all Guaranties and other contingent
              obligations of Borrower and the Consolidated Subsidiaries for
              financing of the CareStream Operations shall not exceed
              $5,000,000, and shall be fully assumed and indemnified against by
              Fox Health pursuant to the CareStream Indemnity, and (B) neither
              Borrower or any Consolidated Subsidiary will have any other
              liabilities or obligations to, or any agreement to provide
              financial support for, the CareStream Operations.

                     (iii)  The consummation of the CareStream Transactions
              will not, and Borrower hereby agrees that the consummation of the
              CareStream Transactions shall not, violate the terms of, or give
              rise to a default under, the 7.09% Notes, the 7.09% Note

              and instruments evidencing the Revolving Receivables Purchase
              Program or any other material agreement, any law, rule or
              regulation, or any order, writ, judgment, injunction, decree,
              determination or award, to which Borrower or any Consolidated
              Subsidiary is a party or by which it or any of its material
              Assets are bound or affected.  None of the CareStream
              Transactions will have a Material Adverse Effect.

                     (iv)   After giving effect to the CareStream Transactions,
              Borrower and each of the Operating Subsidiaries will be Solvent,
              both as a separate corporate entity and on a consolidated basis
              with its Subsidiaries.

              (c)    On the basis of the representations and warranties in this
Section 3 and in Section 5 of this Seventh Amendment, and subject to Section 4
of this Seventh Amendment, Lenders executing this Seventh Amendment hereby (i)
waive, in this specific instance, the provisions of the Loan Agreement set

              material Assets are bound or affected, (D) that the CareStream
              Pledge Agreement creates a valid and enforceable pledge of and
              security interest in the capital stock and assets intended to be
              subject thereto, and (E) as to such other matters as
              Administrative Agent deems appropriate.
