ITEM 2.    ACQUISITION OR DISPOSITION OF ASSETS

During the period from January 1, 2003 to August 7, 2003, Washington Real Estate Investment Trust (“WRIT”) purchased three real estate properties, which, individually are insignificant as defined in Regulation S-X, but in the aggregate, constitute a “significant amount of assets” as defined in Regulation S-X. When acquisitions are individually insignificant but significant in the aggregate, Regulation S-X requires the presentation of audited financial statements for assets comprising a substantial majority of the individually insignificant properties. WRIT’s 2003 real estate asset purchases first exceeded the minimum level of significance upon the August 7, 2003 purchase of an office building located in Washington, D.C.

On August 7, 2003, WRIT purchased 1776 G Street, an eight-story office building, containing 262,000 rentable square feet, located in Washington, D.C., for a contract purchase price of $84.8 million. The contract purchase price was paid in cash. On the date of acquisition, 1776 G Street was 88.0% leased. 1776 G Street constitutes a “substantial majority” of the assets acquired by WRIT through the period ended August 7, 2003 as defined in Regulation S-X.
