     WHEREAS, Purchaser and Sellers entered into that certain Purchase and
Sale Agreement, effective as of March 17, 1994 (the "Contract") regarding the
purchase of the Facilities (as defined in the Contract).

     WHEREAS, Purchaser and Sellers desire to amend the Contract to correct
or clarify certain matters.

     NOW, THEREFORE, in consideration of the foregoing premises, the mutual
covenants set forth herein and other good and valuable consideration the
receipt and sufficiency of which is hereby acknowledged, Purchaser and
Sellers hereby agree that the Contract is hereby amended as follows:

     1.   Page 28 of the Contract is hereby deleted in its entirety and the
attached Page 28 is inserted in lieu thereof.

     2.   Section 8.03(a) of the Contract is hereby deleted in its entirety
and the following is inserted in lieu thereof:

          (a)  The "Rentals" as defined in the Facilities Leases
          shall be adjusted between Purchaser and Sellers as of
          12:01 a.m. on the Closing Date.  Notwithstanding anything
          in Section 8.03 to the contrary, the parties agree that
          with regard to the adjustment and proration of Percentage
          Rental, such proration shall be made at the time the
          Percentage Rental is payable as specified in accordance
          with the Facilities Leases.

     3.   Section 2.07(a) of the Contract is hereby deleted in its entirety
and the following is inserted in lieu thereof:

          (a)  Defective Facilities Identified During the Review
          Period.  In the event (i) Purchaser reasonably determines
          that a Facility has structural, environmental, legal or
          operational defects or conditions that would require
          expenditures equal to or greater than seven and one-half
          percent (7.5%) of the amount of the Purchase Price
          allocated to such Facility in order to bring such
          Facility into a satisfactory condition in accordance with
          prevailing senior living community industry standards
          (any such Facility being hereinafter referred to as a




          "Defective Facility"), and (ii) Purchaser provides
          written notice thereof to Sellers no later than the
          expiration of the Review Period, time being of the
          essence, specifying the Facility or Facilities Purchaser
          wishes to be deleted, Sellers, shall, subject to
          paragraph (c) below, be required to delete such Facility
          or Facilities from the sale contemplated hereunder. 
          Prior to Closing, Sellers agree to enforce all rights
          available against third parties, including, without
          limitation, MSLS, and to cause any and all defects or
          conditions so identified by Purchaser that are the
          obligations of such third parties to be corrected, it
          being expressly understood and agreed that nothing
          contained herein shall be construed to relieve any such
          parties from any obligations with respect to such
          matters.

     4.   If any terms and conditions of this Amendment conflict with the
terms and conditions of the Contract, the terms and conditions of this
Amendment shall prevail.  Except as specifically modified herein, the
Contract is and remains in full force and effect.

     5.   Any capitalized terms used herein but not defined herein shall have
the same meaning as set forth in the Contract.

     6.   This Amendment may be executed in counterparts, all of which taken
together shall constitute one document.

     IN WITNESS WHEREOF, the parties hereto have executed this Amendment as
of the 7th day of April, 1994.

          Sellers shall perform all of the adjustments, including any not
          specifically referred to herein, which are appropriate and usual. 
          The adjustments hereunder shall be calculated or paid in an
          amount based upon a fair and reasonable estimated accounting
          performed and agreed to by representative of Sellers and
          Purchaser at the Closing.  Subsequent final adjustments and
          payments shall be made in cash or other immediately available
          funds as soon as practicable after the Closing Date, and in any
          event within ninety (90) days after the Closing Date, based upon
          an agreed accounting performed by representatives of Sellers and
          Purchaser.  In the event the parties have not agreed with respect
          to the adjustments required to be made pursuant to this Section
          8.03 within such ninety-day period, upon application by either
          party, the Accountant shall determine any such adjustments which
          have not theretofore been agreed to between Sellers and
          Purchaser.  The charges of the Accountant shall be borne fifty
          percent (50%) by Sellers and fifty percent (50%) by Purchaser.

               (d)  Sellers and Purchaser agree that the Title Company
          shall retain from the Sellers' Funds such amounts as may be
          necessary to discharge any monetary encumbrances (other than
          Permitted Encumbrances) affecting any Facility.  The closing
          statement agreed to among the Title Company, Sellers and
          Purchaser shall reflect such use of the Sellers' Funds.

               (e)  Purchaser and Sellers acknowledge that (x) Sellers have
          applied for and there is pending with respect to the Facility
          located in Silver Spring, Maryland a Certificate of Need for
          sixteen (16) skilled nursing beds and (y) the Purchase Price has
          been determined and agreed upon in recognition of the fact that
          such Certificate of Need will not be granted prior to the
          Closing.  If, for any reason, such Certificate of Need is
          irrevocably approved and issued prior to the Closing, the
          Purchase Price shall be increased by an amount equal to
          $1,000,000.  Furthermore, if such Certificate of Need shall be
          irrevocably approved and issued on or before the date two (2)
          years after the Closing Date, Purchaser shall pay to Sellers,
          within ten (10) days thereafter, $1,000,000 in immediately
          available federal funds to such account or accounts as Sellers
          may designate.  The provisions of this section shall survive the
          Closing.

               (f)  Purchaser and Sellers acknowledge that the Purchase
          Price of $320,000,000 is based in part on the minimum and
          percentage rentals payable by MSLS as tenant under the Facilities
          Leases.  Under the Facilities Leases, the percentage rents are
          equal to the product of net receipts over an aggregate sales
          breakpoint of $71,513,000.  If, prior to the Closing Date, the
          aggregate sales breakpoint is reduced pursuant to lease
          amendments to the Facilities Leases, in form and substance
          reasonably acceptable to Purchaser, the Purchase Price shall be
          increased by an amount equal to nine (9) times the product of (x)
          the reduction in the aggregate net sales breakpoint and (y) 4.5%;
          provided, however, in no event shall the Purchase Price increase
          pursuant to this Section by an amount in excess of Two Million
          Dollars ($2,000,000).  An example of such an adjustment is set
          forth on Exhibit B.
