A Special Meeting of Stockholders of BioMed Realty Trust, Inc. (the “Company”) was held on January 21, 2016 (the “Meeting”) in connection with the Agreement and Plan of Merger, dated as of October 7, 2015, among the Company, BioMed Realty, L.P., BRE Edison Holdings L.P., BRE Edison L.P. and BRE Edison Acquisition L.P. (the “Merger Agreement”), pursuant to which the Company will merge with and into BRE Edison L.P. (the “Merger”), with BRE Edison L.P. surviving the Merger.

At the Meeting, the following proposals were submitted to a vote of the holders of the Company’s common stock, each of which is described in detail in the definitive proxy statement filed by the Company with the Securities and Exchange Commission on December 7, 2015, as may be amended or supplemented from time to time. A quorum was present for the Meeting, and a summary of the voting results for each proposal is as follows:

Proposal 1: To approve the Merger and the other transactions contemplated by the Merger Agreement.

Proposal 1 was approved by the Company’s stockholders, as the number of votes in favor of Proposal 1 constituted the affirmative vote of the holders of a majority of the Company’s outstanding shares of common stock as of the record date for the Meeting.

Proposal 2: To approve, on a non-binding, advisory basis, the compensation that may be paid or become payable to the named executive officers of the Company that is based on or otherwise relates to the Merger.

Proposal 2 was approved by the Company’s stockholders, as the number of votes in favor of Proposal 2 constituted the affirmative vote of a majority of the votes cast on the proposal.

Proposal 3: To approve any adjournments of the Meeting for the purpose of soliciting additional proxies if there were not sufficient votes at the Meeting to approve Proposal 1.

Because there were sufficient votes at the Meeting to approve Proposal 1, Proposal 3 was not submitted to the Company’s stockholders for approval at the Meeting.

On January 21, 2016, the Company issued a press release announcing the results of the voting at the Meeting, a copy of which is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

(d) Exhibits.
