GMH Communities Trust Completes Sale of Military Housing Division to Balfour Beatty plc for Approximately $350.5 Million

NEWTOWN SQUARE, Pa., April 30 /PRNewswire-FirstCall/ -- GMH Communities Trust today announced the completion of the sale of its military housing division to a U.S. subsidiary of Balfour Beatty plc ("Balfour Beatty"). The purchase price paid by Balfour Beatty at closing totaled approximately $350.5 million. Approximately $62.1 million of the proceeds was used to repay in full GMH's note facility, including unpaid principal, interest and related costs, with Merrill Lynch, Pierce, Fenner & Smith Incorporated.

As previously announced, GMH intends to make two separate, special distributions to GMH's common shareholders and the unitholders of GMH Communities, LP, (the "Company Operating Partnership"). The Company's Board of Trustees has declared an initial special distribution of $3.10 per share/unit to the holders of the Company's common shares and unitholders of the Company Operating Partnership, which represents a substantial portion of the proceeds from the sale of the military housing division. This distribution will be payable on May 15, 2008 to shareholders and unitholders of record as of the close of business on May 10, 2008. The initial distribution totals approximately $221.1 million in the aggregate. The remainder of the proceeds from the military housing transaction will be retained as a reserve fund pending the closing of the proposed merger of the Company with American Campus Communities . The proposed merger is currently anticipated to occur during the second quarter of 2008, subject to the approval of the Company's shareholders and assuming that the other conditions in the merger agreement are satisfied or waived.

It is currently anticipated that there will be an additional distribution to shareholders and unitholders of approximately $0.98 per share/unit payable immediately prior to the proposed merger with ACC, which represents the remaining proceeds from the sale of the military housing division.

The Company has filed a definitive proxy statement with the Securities and Exchange Commission in connection with the proposed merger with ACC. The definitive proxy statement was mailed to GMH shareholders on or about April 29, 2008. A special meeting of the Company's shareholders has been scheduled for June 10, 2008 at 11 a.m. local time, at the Philadelphia Marriott West, 111 Crawford Avenue, West Conshohocken, PA 19428, to vote on the proposed merger.
