Liberty Property Trust

WHAT:        Liberty Property Trust (NYSE:LRY) will announce that
             Chefs Georges Perrier and Chris Scarduzio (partners in
             Brasserie Perrier, Brasserie Perrier at Boyds, and Mia at
             Caesars Atlantic City) will launch a world-class
             restaurant in Comcast Center when the tower opens in late
             2007. The name of the restaurant will be revealed at the
             event on Tuesday, November 29, when the chefs come to the
             construction site (17th St. & JFK Blvd.) to prepare and
             serve a lunch of Beef Bourguignon and Rice Pilaf for the
             more than 80 construction workers serving at the
             location.

WHY:         This event will serve two purposes: to celebrate the
             announcement of the restaurant and thank the project's
             construction crew.

             Comcast Center will be Philadelphia's foremost office
             environment, as well as an exciting new gateway to the
             city for thousands of people each day.  Perrier and
             Scarduzio's restaurant will anchor 40,000 square feet of
             restaurant and retail space.  The restaurant will also
             feature a seasonal outdoor cafe on Comcast Center's
             sizeable public plaza.

WHEN:        Lunch will be served from 11:45 a.m. - 12:30 p.m.

ABOUT COMCAST CENTER:
             Upon completion, Comcast Center will rise 975 feet,
             making it the tallest building between New York and
             Chicago. The building is unique not only in height, but
             also in its world class design and the amenities it
             offers. The 57-story, state-of-the-art tower will feature
             a half-acre public plaza, a dramatic 120-foot high winter
             garden, along with multiple three-story stacked atria.
             Liberty Property Trust has designed Comcast Center as a
             sustainable building with the goal of achieving a LEED
             certification from the U.S. Green Building Council.
