                         TENANT SUBORDINATION AGREEMENT

        THIS TENANT SUBORDINATION AGREEMENT made as of the _______ day of
February, 1997 by and between J. A. Hunt Services, Inc., a ___________________
corporation (the "Tenant") and Mercantile-Safe Deposit
and Trust Company, a Maryland banking institution (the "Bank").

        WHEREAS, the Tenant is the lessee under a certain lease (the "Lease")
dated April 1, 1995 from Dialysis Corporation of America, a Florida corporation
(the "Landlord"), to Tenant, of certain real property, together with the
improvements thereon, known as 27 Miller Avenue, located in Lemoyne, Cumberland
County, Pennsylvania, as more particularly described in the Lease (the
"Premises");

        WHEREAS, the Bank has made a loan to Landlord and secured said loan by
a Mortgage and Security Agreement dated November 30, 1988 on the Premises (the
"Mortgage"); and

        WHEREAS, at the request of the Landlord and in consideration of the
making of said loan by the Bank, the Tenant has agreed to subordinate the Lease
to the Mortgage.

        NOW, THEREFORE, THIS SUBORDINATION AGREEMENT WITNESSETH, that for
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto do hereby agree and covenant as follows:

        1.  Tenant hereby acknowledges and agrees that the Lease is and shall
be (i) subordinate to the Mortgage, and (ii) subject and inferior to the
Mortgage.

        2.  Should the Premises be transferred to any person or party other
than the Landlord by reason of foreclosure of or other proceedings brought
pursuant to or under the Mortgage, Tenant shall attorn to and be bound to said
transferee under all of the terms, covenants and conditions of the Lease for
the remaining balance of the term thereof and any extensions or renewals
thereof, with the same force and effect as if the transferee was the lessor
under the Lease.

        3.  Unless Tenant is in default under the Lease, the Lease shall not be
terminated, nor shall Tenant's use, possession or enjoyment of the Premises be
interfered with, by reason of any foreclosure proceeding or other action
brought pursuant to or under the Mortgage.

        4.  Each party hereto does hereby agree to execute, acknowledge and
deliver to the other such further instruments as may be necessary to effectuate
the purposes of this subordination, attornment and non-disturbance.
