WASHINGTON REAL ESTATE INVESTMENT TRUST COMPLETES

OFFERING OF $250 MILLION OF SENIOR UNSECURED NOTES DUE 2020

Washington Real Estate Investment Trust (WRIT) (NYSE: WRE) announced today that it completed its previously announced underwritten public offering of $250 million aggregate principal amount of senior unsecured notes due 2020 under its shelf registration statement filed with the Securities and Exchange Commission.

WRIT intends to utilize the net proceeds from the offering for the purchase of its outstanding 3 7/8% convertible senior notes due 2026 and 5.95% senior notes due 2011 pursuant to the previously announced tender offers for these notes, each of which commenced on September 23, 2010. Remaining net proceeds, if any, are intended to be used to repay borrowings under WRIT’s lines of credit or for general corporate purposes.

The tender offers were conditioned on WRIT’s issuance of debt having an aggregate principal amount of at least $250 million in one or more debt financings on terms reasonably satisfactory to WRIT. Such condition has been satisfied by the completion of the offering today.
