                  the APS Lenders agree, upon the terms and subject to the
                  conditions herein set forth, to make a loan to the Borrower at

                  under the Credit Agreement to finance Capital Expenditures for
                  the exercise of the purchase options referred to in Section
                  6.04(c), then proceeds of the APS Acquisition Loan in an
                  amount not in excess of $11,200,000 may also be used for
                  working capital and general corporate purposes of the Borrower

                  executed to the Termination Date or the earlier date of


                                       3

                  commitment fee with respect to the APS Acquisition Loan
                  commitment for the period commencing on the Third Amendment
                  Effective Date to the Termination Date or the earlier date of
                  termination of the Commitment (collectively, the "Commitment
                  Fee"), each computed (on the basis of the actual number of
                  days elapsed over a year of 360 days) at the rate of one-half
                  of one percent (1/2 of 1%) per annum on the average daily
                  Unused Total Commitment."

Credit Agreement is hereby amended by adding as paragraphs "(c)" and "(d)"

                  in an amount not to exceed $11,200,000 to exercise the
                  purchase options for the properties known as the Ansted Health
                  Care Center, Hilltop Nursing Center and Knollwood Manor and
                  the amount so expended will not be treated as a Capital
                  Expenditure under paragraphs (a) or (b) of this section 6.04.

                  (d) In addition to the foregoing, the Borrower shall be
