Company Background and Highlights

Second Quarter 2008

Washington Real Estate Investment Trust (the “Company”) is a self-administered, self-managed, equity real estate investment trust (REIT) investing in income-producing properties in the greater Washington metropolitan region. WRIT is diversified, as it invests in multifamily, retail, industrial/flex, office, and medical office properties.

During second quarter 2008, WRIT focused on improving its portfolio through acquisitions and dispositions, while maintaining its strong balance sheet. This quarter, WRIT acquired a medical office building for a $6.5 million and entered into a purchase agreement to acquire a D.C. office building for $182 million, and disposed of two flex properties for a net book gain of $15.3 million. Also this quarter, WRIT issued $90.5 million of equity and refinanced $81 million of short-term debt with long-term debt at a rate of 5.71% and an 8-year maturity. WRIT’s Board of Trustees appointed Wendelin (Wendy) A. White, Esq. and Terence C. Golden to serve as trustees. WRIT also increased its dividend for the 38th consecutive year. Earlier this year, WRIT increased its borrowing capacity on its unsecured credit facilities to $337 million and refinanced its only debt maturity during 2008.

On May 21, 2008, WRIT acquired Sterling Medical Office Building, a 36,000 square foot medical office building located in Sterling, Virginia for $6.5 million. Demand for medical office space in the area is driven by its proximity to Inova Loudoun Hospital and Reston Hospital Center. WRIT expects to achieve a first-year, unleveraged yield of 7.6% on a cash basis and 7.9% on a GAAP basis. The acquisition was funded with cash from operations.

On June 16, 2008, WRIT entered into a purchase agreement to acquire 2445 M Street, a 290,000 square foot office building located in Washington, DC, for approximately $182 million. The property is 100% leased and strategically positioned between Georgetown and the Central Business District in the West End submarket of Washington, DC. WRIT anticipates the closing of the acquisition will take place no later than the fourth quarter of 2008.

On June 6, 2008, WRIT completed the sale of Sullyfield Commerce Center and The Earhart Building, totaling 336,000 square feet for $41.1 million. The industrial/flex properties, located in Chantilly, VA, were acquired in 2001 and 1996, respectively. WRIT achieved a net book gain of $15.3 million on the sale of the properties and a combined 13.0% unlevered internal rate of return during ownership. Proceeds from the sale will be reinvested in a 1031 exchange.

During the last year, WRIT completed several ground-up development projects. In third quarter 2007, WRIT completed base construction on Dulles Station, a 180,000 square foot development project of Class A office space located in Herndon, VA. The building, prominently visible from the Dulles Toll Road, is part of a larger mixed-use development which will include 1,095 multifamily units and 56,000 square feet of retail and restaurant space.

In fourth quarter 2007, WRIT completed construction at Bennett Park. Bennett Park is a ground-up development project in Arlington, VA consisting of high-rise and mid-rise Class A apartment buildings with a total of 224 units and 5,800 square feet of retail space. The property was 55% leased at quarter-end.

In first quarter 2008, WRIT began delivering units at The Clayborne Apartments. The Clayborne is a ground-up development project in Alexandria, VA, adjacent to our 800 South Washington retail property. The project consists of a 74-unit Class A apartment building that will include 2,700 square feet of additional retail space. The property was 36% leased at quarter-end.
