Item 1.01. Entry into a Material Definitive Agreement.

      On July 11, 2007, WRT Realty, L.P. (the "Partnership") entered into a
Second Amended and Restated Limited Liability Company Agreement (the "Operating
Agreement") of Lex-Win Acquisition LLC ("Lex-Win"), among The Lexington Master
Limited Partnership, the Partnership, VII Wells Holdings, L.L.C., Square Mile
Value LLC ("Square Mile") and Stark Wells Holdings, LLC ("Stark"). The purpose
of amending and restating the Operating Agreement was to admit Square Mile and
Stark as members of Lex-Win. As a result of this admission, the Partnership's
interest in Lex-Win was reduced to 28% of the outstanding membership interests.

      The foregoing description is qualified in its entirety by reference to the
Operating Agreement, which will be attached as an exhibit to Winthrop Realty

which Winthrop Realty Trust intends to file in November 2007.

at 5:00 p.m. New York time on July 20, 2007 unless the offer is further
extended.
