1.             Organization

Corporate Office Properties Trust (“COPT”) and subsidiaries (collectively, the “Company,” “we” or “us”) is a fully-integrated and self-managed real estate investment trust (“REIT”) that focuses primarily on strategic customer relationships and specialized tenant requirements in the United States Government and defense information technology sectors and data centers serving such sectors.  We acquire, develop, manage and lease office and data center properties that are typically concentrated in large office parks primarily located adjacent to government demand drivers and/or in strong markets that we believe possess growth opportunities.  As of June 30, 2011, our investments in real estate included the following:

·                  249 wholly owned operating office properties totaling 20.2 million square feet;

·                  17 wholly owned office properties under construction, development or redevelopment that we estimate will total approximately 2.2 million square feet upon completion, including two partially operational properties included above;

·                  wholly owned land parcels totaling 1,516 acres that we believe are potentially developable into approximately 13.0 million square feet;

·                  a wholly owned, partially operational, wholesale data center which upon completion is expected to have an initial stabilization critical load of 18 megawatts; and

·                  partial ownership interests in a number of other real estate projects in operations, under construction or development or held for future development.

We conduct almost all of our operations through our operating partnership, Corporate Office Properties, L.P. (the “Operating Partnership”), of which we are the managing general partner.  The Operating Partnership owns real estate both directly and through subsidiary partnerships and limited liability companies (“LLCs”).  A summary of our Operating Partnership’s forms of ownership and the percentage of those ownership forms owned by COPT as of June 30, 2011 follows:

Three of our trustees also controlled, either directly or through ownership by other entities or family members, an additional 5% of the Operating Partnership’s common units (“common units”) as of June 30, 2011.

In addition to owning real estate, the Operating Partnership also owns entities that provide real estate services such as property management, construction and development and heating and air conditioning services primarily for our properties but also for third parties.
