OAK RIDGE OFFICE PORTFOLIO


Additional Information

o The loan is secured by 6 Class A office buildings in Oak Ridge, TN. The five Tech Center buildings are single-story, and the Commerce Park building is 4-stories. The buildings are all located in close proximity to each other and contain a total of 413,965 square feet.

o The subject properties are located immediately next to the Oak Ridge Reservation (ORR) facility, an enormous laboratory and R & D campus that plays an integral role in the federal government's science, energy and national security arenas. The ORR facility includes the Oak Ridge National Laboratory (ORNL), the K25 site, and the Y12 National Security Complex. The Spallation Neutron Source is currently being constructed in the facility and should be completed by 2006. The expected cost of this facility is estimated to be $1. 4 billion and $278 million has been appropriated by Congress thus far for the construction. The ORR is behind heavy, gated security and is controlled exclusively by the Department of Energy (DOE).

o The properties were developed by the current owner, the Cowperwood Company, in 1991 to provide Class A space in a market that lacked sufficient quality space for government contractors connected to the work done at the Oak Ridge Reservation facilities. The portfolio represents most of the leaseable Class-A office space in the market.

o Tenants have typically leased space to end co-terminously with their DOE contracts.

o The subject properties have had a historically low vacancy rate as indicated by the combined average annual vacancy rate for the portfolio since 1991 of 1.90%.
