LIBERTY PROPERTY TRUST ANNOUNCES
THIRD QUARTER RESULTS

Malvern, PA — Liberty Property Trust (NYSE:LRY) reported that net income per common share (diluted) increased to $.49 per share for the quarter ended September 30, 2003, from $.47 per share (diluted) for the quarter ended September 30, 2002.

Funds from operations available to common shareholders (diluted) (“FFO”) for the third quarter of 2003 increased to $.85 per share from $.80 per share for the third quarter of 2002. FFO is a non-GAAP financial measure. A reconciliation of GAAP net income to FFO is included in the financial tables accompanying this press release.

Third quarter 2003 results include $3.8 million, or approximately $.05 per share, in lease termination fees.

Third quarter 2002 results reflect recent guidance and clarifications by the Securities and Exchange Commission. The SEC’s July 31, 2003 clarification of certain issues surrounding FASB-EITF Topic D-42, “The Effect on the Calculation of Earnings per Share for the Redemption or Induced Conversion of Preferred Stock,” requires the excess of preferred share redemption over carrying amount to be classified as a reduction in income available to common shareholders. Liberty redeemed its Series A Preferred Shares during the third quarter of 2002, and recorded the redemption in accordance with GAAP at that time. The application of this guidance has resulted in a $.05 decrease in both net income per common share (diluted) and FFO per share for the third quarter of 2002, and for the full year ended December 31, 2002.

In addition, on October 1, 2003, the National Association of Real Estate Investment Trusts published new guidance requiring impairment write-downs to be included in FFO. This clarification, which reflects a recent SEC staff’s position, has resulted in a $.07 decrease in FFO per share (diluted) for the third quarter of 2002, and for the full year ended December 31, 2002, with regard to Liberty’s sale of 28 industrial properties in November, 2002.

“Although economic data suggests that the broad economy is showing signs of improvement, real estate markets continue to suffer from eroding occupancy and pricing pressure. Given these circumstances, Liberty continues to perform well by maintaining occupancy and identifying select value-adding opportunities,” said William P. Hankowsky, Liberty’s chairman and chief executive officer. “Looking ahead, we expect 2004 to be a year of transition, with markets achieving varying degrees of stability by year-end, and opportunities for investment potentially increasing.”

RKL operates in the United Kingdom, and owns six buildings which contain 210,000 square feet of leaseable space. RKL is party to a contract with the County of Kent which contract entitles RKL to participate in proceeds realized from the sale of residential land parcels to homebuilders.

During the quarter, Liberty completed lease transactions totaling more than 2.9 million square feet of space.

Same Store Performance: Property level operating income for same store properties decreased by 1.7 percent on a cash basis and by 1.9 percent on a straight line basis for the quarter. For the nine month period ended September 30, property level operating income decreased by 2.6 percent on a cash basis and by 2.7 percent on a straight line basis.
