AMENDMENT TO
                             LOAN AGREEMENT

     THIS AMENDMENT TO LOAN AGREEMENT (this "Amendment") is made as of
December 1, 1997, by and between DIALYSIS CORPORATION OF AMERICA, a
Florida corporation (the "Borrower"), having an address at 2337 West 76th
Street, Hialeah, FL  33016, and MERCANTILE-SAFE DEPOSIT AND TRUST COMPANY,
a Maryland banking institution (the "Bank").

                               RECITALS

     Pursuant to a certain Loan Agreement (which Loan Agreement, as the
same has or may at any time and from time to time be amended, restated,
supplemented or otherwise modified, is herein called  the "Loan Agreement")
dated November 30, 1988, between the Borrower and the Bank, the Borrower
obtained a loan (the "Loan") from the Bank in accordance with and subject
to the provisions of the Loan Agreement.

     The Borrower's obligation to repay the Loan with interest is
evidenced by a Promissory Note dated November 30, 1988 in the principal
amount of $600,000.00 from the Borrower to the Bank (the "Note").  The
Note has been amended pursuant to a First Amendment to Promissory Note of
even date herewith.

     The Note is secured by a Deed of Trust and Security Agreement from
the Borrower to Stephen D. Palmer and William W. Duncan, Jr., trustees,
for the benefit of the Bank, covering certain real property as described
therein (the "Deed of Trust").  The Borrower's obligations under the Note
are also secured by an  Assignment of Rents and Leases dated November 30,
1988 by and between the Borrower and the Bank (the "Assignment of Rents
and Leases").

     The Borrower has requested the Bank to delete the call provisions of
the Loan Agreement and to make certain other accommodations and the Bank
has agreed to do so  provided that, among other things, the provisions of
the Loan Agreement are amended and modified in accordance with the pro-
visions of this Agreement.

                              AGREEMENTS

     NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties hereto, the Bank and the Borrower agree as
follows:

     1.  Recitals.  The Bank and the Borrower acknowledge that the above
         --------
Recitals to this Amendment are true and correct, and agree that the same

(including, without limitation, the terms "Loan Documents", "Default",
