/1/ Comparing Q2 2002 to Q2 2001, the 28% decline in FAD per share is primarily
attributable to a $3.0 million increase in Major Renovations, Expansions and
Development in Q2 2002. These major renovations include projects at three office
buildings: 1901 Pennsylvania Avenue, N. W. - a complete facade renovation, 51
Monroe Street, Rockville, MD - a lobby renovation, 7900 Westpark Drive - a
lobby/hallway renovation and at Westminster Shopping Center, Westminster, MD for
renovation and re-tenanting. Project completion is expected in 2002.

/2/ FAD per share - fully diluted, excluding $3.0 million of Renovations,
Expansions and Development for Q2 2002 is $0.38. This amounts to an (11.3%)
decline when compared to Q2 2001.
