8-Story Office Property, Second Building to Come, to be Named Piedmont Pointe

NORCROSS, Ga. (Dec. 19, 2007) – Piedmont Office Realty Trust Inc. announced today it has acquired the 100 percent ownership interest of Rock Spring LLC, the entity owning Opus Center at Rock Spring Park I, a recently completed Class-A office building in suburban Washington, D.C. Piedmont also has signed a contract to purchase the entity that owns Opus Center at Rock Spring Park II, an adjacent building under construction.

The two highly efficient eight-story buildings will be connected, totaling approximately 407,000 square feet. The buildings will include outdoor terrace areas, a fitness center and an underground executive parking garage, as well as an adjacent parking structure.

The buildings will be renamed Piedmont Pointe I and II.

The property, part of Rock Spring Park, is located on Rockledge Drive in Bethesda, in close proximity to Interstates 495 and 270 and a short drive from Washington, D.C. Both buildings are now available for leasing; Jones Lang LaSalle will market leasing opportunities.

“This transaction is a good example of our strategy in action – quality properties in one of our concentration markets with an emphasis on long-term growth,” said Raymond L. Owens, executive vice president, capital markets, for Piedmont. “We’re very pleased with the transaction, and believe these buildings should make strong additions to the Piedmont portfolio.”

“These are excellent new office buildings in what we regard as one of the finest corporate parks in the Washington area,” said Wil Stone, senior vice president, capital markets, who represented Piedmont. “We like the area, and we like the real estate.”

The seller was the developer, Opus East, a member of The Opus Group. Terms were not announced. Opus East was represented by Eric Berkman and Steven Gichner of Grubb & Ellis. Piedmont specializes in Class-A office properties. As of Sept. 30, Piedmont owned 82 buildings totaling more than 21 million square feet in 23 states and Washington, D.C., with a 94 percent lease rate.
