Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) This Form 4 is amended solely to properly reflect the actual Amount of Securities Beneficially Owned Following the Reported Transaction due to the distribution of shares from the Company's Deferred Compensation Plan prior to January 5, 2006, which was subsequently discovered and thus needs to be adjusted downward here by 6,859 shares. No shares were sold by this Reporting Person associated with these 6,859 shares, but rather this Form 4 merely corrects an overstatement of shares carried over as Prentiss Properties shares from the merger.
(2) There was no indirect transaction on the above date. The indirect ownership is being disclosed for informational purposes only.
(3) Options fully vested when issued on January 5, 2006 (Legacy PPT Options converted to BDN Options).

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
