FOR IMMEDIATE RELEASE

RICHMOND, VIRGINIA

OCTOBER 1, 1996


           UNITED DOMINION REALTY TRUST AND SOUTH WEST PROPERTY TRUST
                            ANNOUNCE MERGER AGREEMENT

United  Dominion Realty Trust,  Inc.  (NYSE:  UDR) and South West Property Trust
Inc.  (NYSE:  SWP) today  announced  the  execution  of a  definitive  Agreement
pursuant to which South West would be merged  into United  Dominion.  The merger
which was approved  unanimously  by both Boards of Directors  will combine South
West's 14,975  apartment  homes  (including its development  portfolio),  80% of
which  are in  Texas,  with  United  Dominion's  41,004  apartment  homes in the
Southeast.

Following  the  merger,  United  Dominion,  with 55,979  apartment  homes in 210
communities, will be the largest REIT developer, owner and manager of apartments
in the southeastern and southwestern United States.

Based upon the closing  stock price of United  Dominion on  September  30, 1996,
shareholders  of South West would receive  approximately  $312 million of United
Dominion common stock.

Under the terms of the Agreement, each share of South West will be exchanged for
1.0833 shares of United Dominion provided that United Dominion's average closing
price  during the pricing  period is $13 7/8 or higher.  If the average  closing
price is less than $13 7/8, then the exchange ratio will be adjusted  upwards to
provide a $15 value for each South West share. This exchange ratio assures South
West shareholders  that their current dividend rate will not be reduced.  United
Dominion is not required to offer more than 1.1215 shares, and South West is not
required to accept less than $15 per share in value. The Agreement is subject to
completion of due diligence by both parties, regulatory approval and approval by
both companies' shareholders.

The merger has been structured as a tax-free  transaction and will be treated as
a purchase for  accounting  purposes.  The merger is expected to be effective at
the close of business on December 31, 1996.

Three of South West's executive officers, John S. Schneider,  Chairman and Chief
Executive Officer, Robert F. Sherman,  President and Chief Operating Officer and
David L. Johnston,  Executive Vice President and Chief  Investment  Officer will
join United Dominion as executive  officers.  Mr. Schneider,  along with Mark J.
Sandler,  Robert W.  Scharar and Ira T.  Wender,  (currently  Directors of South
West) will join United Dominion's Board of Directors.

John  Schneider,  South West's CEO,  stated that the merged  companies  span the
southeastern  and  southwestern  United  States,  two of the most vibrant growth
areas  of  the  country.   They  bring  together  United  Dominion's   extensive
acquisition  expertise and South West's  proven  development  capabilities.  The
combined  Company,  with over two  billion  dollars in assets,  should also have
greater  access to lower cost  capital.  Consequently,  South West's  management
believes that this merger creates a unique  opportunity for its  shareholders to
participate in the consolidation and growth of the REIT industry.


Mr. Schneider  further stated that United Dominion and South West have each been
in the apartment  business since 1973, and the  combination  will bring together
one of the strongest and most experienced  management teams in the industry.  In
addition,  the  merger  should  provide  opportunities  to  realize  significant
administrative  cost  savings  which are  expected to have a positive  effect on
shareholder value.

John McCann,  United  Dominion's CEO,  stated that the merger  provides  several
important strategic and operational benefits for United Dominion:

              The apartment sector is rapidly consolidating, permitting dominant
              companies to realize  enhanced access to capital from a variety of
              sources at lower cost. We have participated in this  consolidation
              in a substantial way in the private transaction sector since 1991.
              This  major  transaction  is  our  initial  participation  in  the
              consolidation of public companies.  We are very excited about what
              this merger does for the Company, its shareholders and our future.

              The  merger  should  be  accretive   immediately   to  funds  from
              operations per share.  

              More  than  $300  million  will  be  added  to our  equity  market
              capitalization  which should  provide  increased  liquidity in our
              common stock.  The addition of South West's more than $500 million
              of  apartment  homes  should  provide  economies  of  scale in our
              overall operations.

              About 80% of South West's  apartments  are located in Texas.  This
              represents  a  logical  expansion  of our  geography  and gives us
              instant critical size in Dallas, a long-term growth market.

              South West has developed  successfully in multiple markets in both
              the  southeast  and  southwest.  They  bring  to  us  an  enhanced
              development  capability,  knowledge of the  southwest  markets and
              management depth.

              The expanded geography and greater  development  capabilities will
              provide  more  investment  opportunities  for us to  consider  and
              should result in increased returns on new investments.
