Edmund B. Cronin, Jr., Chairman, President and CEO, stated that, "Commencing
this quarter, WRIT is reporting Earnings Per Share, Funds From Operations Per
Share and Funds Available for Distribution Per Share in order to allow greater
comparability with other public companies and to improve transparency regarding
our dividend paying ability. WRIT's earnings growth is due to the excellent
performance of recent acquisitions, combined with the strong core portfolio net
operating income increase of 8.2%." WRIT's core portfolio excludes properties
not owned for the entirety of both periods being compared.

WRIT is a self-administered, self-managed, equity real estate investment trust
investing in income-producing properties in the greater Washington-Baltimore
region. The Trust owns a diversified portfolio of 58 properties consisting of
10 neighborhood retail centers, 24 office buildings, 15 industrial
distribution/flex properties and 9 multifamily properties.

WRIT's streak of 35 consecutive years of increased earnings per share and 28
consecutive years of increased FFO per share growth spans 4 recessions. WRIT's
dividends have increased every year for 30 consecutive years. During these 30
years, WRIT's dividends have increased 36 times, a record unmatched by any other
publicly traded real estate investment trust. WRIT shares are publicly traded on
the New York Stock Exchange (symbol: WRE).

Acquisitions
- ------------

One Central Plaza located at 11300 Rockville Pike (Route 355) in North Bethesda,
Maryland was acquired for $44.4 million on April 19, 2001. One Central Plaza is
a twelve-story building containing 274,000 rentable square feet of office space
on eight levels and 763 parking spaces on a four-level parking garage. The
building was 100% leased at June 30, 2001. At a purchase price of $162 per
square foot, the building was acquired at a substantial discount to replacement
cost.

WRIT expects this acquisition to produce a first year return on investment of
10.4% on a cash basis and 11.0% on a GAAP basis. From 2001 through 2004,
expiring leases average only 8% of the building's square footage per year.
However, as the rents in these leases average 24% below current market rents,
the cash return on investment is projected to grow to 11.7% over this period.

One Central Plaza, built in 1974, is a landmark on Rockville Pike in the heart
of Montgomery County, Maryland. The property is located directly across from the
entrance to White Flint Mall and two blocks south of the White Flint Metro
Station. Leasing and operational synergies are anticipated at One Central Plaza
as WRIT now owns eight office buildings containing a total of 1.1 million square
feet in the 17 million square foot North Bethesda/Rockville submarket.

Equity Offering
- ---------------

On April 24, 2001 WRIT completed a public offering of 2,535,000 Shares of
Beneficial Interest priced at $22.15 per share. The 2,535,000 shares included
235,000 shares issued pursuant to the exercise of the underwiter's
overallottment option. Merrill Lynch & Co., Inc., Credit Suisse First Boston,
A.G. Edwards & Sons, Inc., Legg Mason Wood Walker, Inc., and BB&T Capital
Markets co-managed the offering.

The $53,000,000 net proceeds from the sale of the shares were used to repay
$43,000,000 in borrowings under the Trust's lines of credit related to WRIT's
acquisition of One Central Plaza on April 19, 2001. The balance has been
invested in marketable securities with the intent to be utilized for the
acquisition of income-producing properties, to expand and/or renovate presently
owned properties and for general corporate purposes.
