                     LIBERTY PROPERTY TRUST ANNOUNCES
                   FOURTH QUARTER AND FULL YEAR RESULTS

Malvern, PA -- Liberty Property Trust (NYSE:LRY) reported that funds
from operations (?FFO?) for the fourth quarter of 2002 decreased to
$.83 from $.86 for the fourth quarter of 2001.  For the year ended
December 31, 2002, FFO per share increased to $3.45 per share from
$3.42 per share for 2001.  The full-year 2002 results were positively
impacted by $.10 in lease termination fees.  A reconciliation of FFO to
GAAP net income is included in the financial statements accompanying
this press release.

Net income per common share (diluted) decreased to $.43 per share for
the quarter ended December 31, 2002, from $.51 per share (diluted) for
the quarter ended December 31, 2001, and decreased to $2.02 per share
for the full year 2002 from $2.15 per share for 2001.  The fourth
quarter and full year results include a $5.3 million impairment loss
due to the write-down of the book carrying value of certain land
parcels.

?Liberty?s seasoned team delivered a strong fourth quarter with 2.5
million square feet of leases executed,? commented William P.
Hankowsky, Liberty?s chief executive officer. ?This was despite the
economy?s uneven performance and the weak real estate markets, as
evidenced by increasing national vacancy rates.  Our strategy and our
strong leasing and management teams continue to provide us with
resilience in these challenging times.?
