Corporate Office Properties Trust Expects Further Delays in Fort Ritchie Litigation

COLUMBIA, Md.--(BUSINESS WIRE)-- Fort Ritchie was closed in 1998 as part of the military's Base Realignment and Closure (BRAC) program. Corporate Office Properties Trust (COPT) purchased 500 acres of the site from PenMar Development Corporation (PenMar) in October 2006 for $4.2 million, and paid approximately $775,000 in November 2007 for the remaining 91.5 acres. Since acquiring the site, COPT has progressed only modestly on plans to redevelop Fort Ritchie into a unique mixed-use development that integrates the Fort's historic stone structures with state-of-the-art office, retail, recreational, and residential facilities.

As a result of pending litigation initiated in May 2005, the United States District Court for the District of Columbia (the Court) required COPT, effective November 2009, to cease further development at Fort Ritchie pending resubmission by the U.S. Army of a revised Record of Environmental Consideration or a Supplemental Environmental Impact Statement, which complies with the Court's order. COPT now expects further delays in this litigation, owing to the discovery of new information relayed this week to the Company by the Army.

On February 15, 2011, the Army disclosed to COPT a study published by the Department of Defense in December 2006 (2006 Report) regarding the testing and use of tactical defoliants/herbicides at various military installations throughout the United States, including Fort Ritchie. In addition, on February 17, 2011, the Army disclosed to COPT a report published in 1956 by the Chemical Corps Research & Development Command Biological Warfare Laboratories titled "Defoliation Investigations During 1954 and 1955" (1956 Report), which describes other testing and the use of tactical defoliants/herbicides at Fort Ritchie.

COPT was not made aware of the 2006 Report, the 1956 Report, or the prior use of tactical defoliants/herbicides at Fort Ritchie until this week. COPT is working with the Army and PenMar to determine the precise locations and extent of the testing conducted within Fort Ritchie and does not have any further details at this time.
