Item 8.01. Other Events.

On February 1, 2007, Equity Office Property Trust (“Equity Office”) received a proposal from Vornado Realty Trust (“Vornado”). The proposal states that Vornado proposes to acquire Equity Office for $56 per common share, payable (i) $31 in cash and (ii) in Vornado common shares having a value (based on an average price during a period prior to the closing specified in the transaction documents) equal to $25, except that the fraction of a Vornado common share that would be issued per Equity Office common share would not be less than .1852 nor more than .2174. The proposal states that this collar assures that the overall value of the Vornado proposal would remain $56 per Equity Office common share so long as the Vornado common share price remains between $115 per share and $135 per share, as compared to Vornado’s closing price of $122.35 on January 31, 2007. A copy of the proposal is attached hereto as Exhibit 99.1 and incorporated herein by reference.

On February 1, 2007, Equity Office issued a press release which is attached hereto as Exhibit 99.2 and incorporated herein by reference.
