                       FIRST AMENDMENT TO CREDIT AGREEMENT


         THIS FIRST AMENDMENT TO CREDIT AGREEMENT (the "First Amendment") is
made as of this 24th day of July, 1997 by and among SUMMIT PROPERTIES
PARTNERSHIP, L.P., a Delaware limited partnership doing business in North
Carolina as SUMMIT PROPERTIES PARTNERSHIP, LIMITED PARTNERSHIP ("Borrower"),
FIRST UNION NATIONAL BANK (formerly known as First Union National Bank of North
Carolina), a national banking association ("FUNB"), WACHOVIA BANK OF NORTH
CAROLINA, N.A., a national banking association ("Wachovia") and FIRST UNION
NATIONAL BANK (formerly known as First Union National Bank of North Carolina), a
national banking association, as agent (in such capacity, "Agent").


                              STATEMENT OF PURPOSE

         The parties hereto have entered into that certain Credit Agreement
dated November 18, 1996 whereby FUNB and Wachovia agree to lend on the terms and
conditions set forth therein up to One Hundred Fifty Million Dollars
($150,000,000.00) on a revolving basis to Borrower (the "Credit Agreement"). The
parties have discovered that one of the provisions of the Credit Agreement
imposed obligations on the Borrower which were not intended by the parties
thereto. The parties desire to correct such provision in order to properly
reflect the intention of all parties.

         NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto hereby agree to
amend the Credit Agreement in the manner set forth below:

         Section 7.12 of the Credit Agreement is hereby deleted and the
following is inserted in lieu thereof:

         "SECTION 7.12. NO ADDITIONAL SECURED RECOURSE DEBT. Neither the
              Borrower nor the Guarantor shall incur any secured debt pursuant
              to which any creditor shall have recourse against the Borrower,
              the Guarantor or any Affiliate of the Borrower or the Guarantor
              other than Secured Recourse Debt permitted under SECTION 8.1.5 and
              Indebtedness secured by one or more the Bond Financed
              Communities."

              All terms beginning with capital letters not defined herein shall
have the meanings set forth for such terms in the Credit Agreement. Except as
expressly set forth herein or as may be necessary to reflect the intention of
the parties hereto as set forth herein, all other terms and provisions of the
Credit Agreement are hereby ratified and affirmed.

         IN WITNESS WHEREOF, the Borrower, the Agent and the Banks have caused
this Amendment to be executed under seal by their respective duly authorized
officers as of the date first set forth above.
