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
$480,000.00 from the Borrower to the Bank (the "Note").  The Note has been
amended pursuant to a First Amendment to Promissory Note of even date here-
with.

     The Note is secured by a Mortgage and Security Agreement from the
Borrower for the benefit of the Bank, covering certain real property as
described therein (the "Mortgage").  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.

valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties hereto, the Bank and the Borrower agree as
