Brandywine Updates Shelf Registration.

PLYMOUTH MEETING, Pa. -- Brandywine Realty Trust (NYSE:BDN) announced today that it, together with its operating partnership subsidiary, have filed with the Securities and Exchange Commission a universal shelf registration statement to register $750 million of debt securities and $750 million of preferred and common and other securities.

The filing would simply replenish the original capacity under the universal shelf registration statement that the Company filed in 2004. The Company issued $525 million of debt securities and $217 million of common equity under the previous registration statement.

The Company's filing of this universal shelf registration statement is consistent with current market practice of providing maximum flexibility to respond to future financing opportunities. The Company has no current plans to issue the securities included in the registration statement, but intends to continue its customary practice of issuing securities from time to time to meet its financing needs.

A registration statement relating to these securities has been filed with the Securities and Exchange Commission but has not yet become effective. These securities may not be sold nor may offers to buy be accepted prior to the time the registration statement becomes effective. This news release shall not constitute an offer to sell or a solicitation of an offer to buy, nor shall there be any sale of the securities in any state in which such offer, solicitation, or sale would be unlawful prior to the registration or qualification of the securities under the securities laws of any such state.
