LIBERTY PROPERTY TRUST COMPLETES PURCHASE
OF REPUBLIC PROPERTY TRUST

Joint Venture Formed with New York State Common Retirement Fund

Malvern, PA and Herndon, VA, October 4, 2007— Liberty Property Trust (NYSE:LRY) and Republic Property Trust (NYSE:RPB) announced that the acquisition of Republic was completed today through the merger of Republic with a wholly owned subsidiary of Liberty and the merger of Republic’s operating partnership with Liberty’s operating partnership. In the mergers, each of the former common shares of Republic and partnership units of its operating partnership was converted into the right to receive $14.70 in cash, without interest. Republic’s common stock will be delisted from the New York Stock Exchange effective at the close of business on October 4, 2007. The portfolio of 14 properties acquired from Republic will be operated in a joint venture between Liberty and New York State Common Retirement Fund, as advised by Heitman. The joint venture, in which Liberty holds a 25% interest, is originally valued at $900 million, and is expected to grow to approximately $2.2 billion through the acquisition and development of additional properties in the Washington, DC and Northern Virginia markets.

“We are very pleased to be up and running in the Washington and Northern Virginia markets,” commented Bill Hankowsky, chairman and chief executive officer. “These transactions provide Liberty with a new platform of quality properties in dynamic markets and a mandate to grow that platform.”

Liberty’s new platform will be led by John Gattuso, senior vice president for urban and national development, who will assume the role of regional director for a new region incorporating Washington, Northern Virginia and the city of Philadelphia. The urban and national development team has developed more than five million square feet of Class A, sustainable projects of national stature, including the Plaza at PPL Center, Comcast Center, and the Philadelphia Navy Yard Corporate Center. Mr. Gattuso will oversee a local team consisting of development, leasing and property management experts from both Liberty and Republic, and from the Washington marketplace.

The properties contributed to the joint venture include 13 operating properties consisting of 24 office buildings and a redevelopment property that, upon completion, will comprise 176,000 square feet of prime office space.
