                           TERM LOAN CREDIT AGREEMENT

         THIS AMENDMENT NO. 4 dated as of May 30, 2000 (the "Amendment") to the
Term Loan Credit Agreement referenced below, is by and among HEALTHCARE REALTY
TRUST INCORPORATED, a Maryland corporation, and CAPSTONE CAPITAL CORPORATION, a
Maryland corporation, as Borrowers, the banks identified therein and BANK OF
AMERICA, N.A. (formerly known as NationsBank, N.A.), as administrative agent.
Terms used but not otherwise defined shall have the meanings provided in the
Term Loan Credit Agreement.

W I T N E S S E T H

         WHEREAS, a $200 million term loan facility, consisting of a $187.4
million Tranche A Term Loan to Healthcare Realty Trust Incorporated ("HRT") and
a $12.6 million Tranche B Term Loan to Capstone Capital Corporation ("CCT", and
together with HRT, the "Borrowers"), was established pursuant to the terms of
that Credit Agreement dated as of October 15, 1998 (as amended and modified, the
"Term Loan Credit Agreement") among HRT and CCT, as Borrowers, the banks
identified therein (the "Banks"), and NationsBank, N.A., (now known as Bank of
America, N.A.), as administrative agent (in such capacity, the "Agent");

         WHEREAS, approximately $42.8 million remains outstanding on the
Tranche A Term Loan and the Tranche B Term Loan has been paid;

         WHEREAS, HRT has requested extension of the Tranche A Term Loan and
certain other modifications to the Term Loan Credit Agreement;

         WHEREAS, the Banks have agreed to the requested extension and
modifications on the terms and conditions set forth herein;

         NOW, THEREFORE, IN CONSIDERATION of the premises and other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows:

         1.   The Term Loan Credit Agreement is amended and modified in the
following respects:

         1.1  The Tranche A Maturity Date is extended to November 30, 2000.

         1.2  The definition of "Applicable  Percentage" in Section 1.1 of the
         Term Loan Credit  Agreement is amended to read as follows:

                    "Applicable Percentage" means, for any day, a per annum rate
              equal to (a) in the case of Eurodollar Loans, 250 basis points
              (2.50%) and (b) in the case of Base Rate Loans, 150 basis points
              (1.50%).

         Provided, however, that if less than $25 million remains outstanding on
         the Tranche A Term Loan on or before July 15, 2000, the definition of
         "Applicable Percentage" in Section 1.1 of the Term Loan Credit
         Agreement shall automatically be amended to read as follows:

   2


                  "Applicable Percentage" means, for any day, a per annum rate
            equal to (a) in the case of Eurodollar Loans, 200 basis points
            (2.00%) and (b) in the case of Base Rate Loans, 100 basis points
            (1.00%).

         2. This Amendment shall be effective upon execution hereof by the Banks
and the Borrowers.

         3. HRT covenants and agrees that, if more than $25 million remains
outstanding on the Tranche A Term Loan on July 15, 2000, HRT will immediately
pay to the Agent, for the ratable benefit of the Banks holding the Tranche A
Term Loan, an additional fee of $150,000.

         4. Except as modified hereby, all of the terms and provisions of the
Term Loan Credit Agreement (including schedules and exhibits) shall remain in
full force and effect.

         5. The Borrowers agree to pay all reasonable costs and expenses of the
Agent in connection with the preparation, execution and delivery of this
Amendment, including the reasonable fees and expenses of Moore & Van Allen,
PLLC.

         6. This Amendment may be executed in any number of counterparts, each
of which when so executed and delivered shall be deemed an original, and it
shall not be necessary in making proof of this Amendment to produce or account
for more than one such counterpart.

         7. This Amendment shall be governed by and construed in accordance with
the laws of the State of North Carolina.
