Cousins Signs American Cancer Society to 274,000-Square-Foot Lease in Downtown Atlanta; Move Brings ACS' International and South Atlantic HQs to Inforum; Building Now 98 Percent Leased.

ATLANTA -- Cousins Properties Incorporated (NYSE:CUZ) announced today it has signed the American Cancer Society to a 274,000-square-foot lease at Inforum, a 994,000-square-foot building in downtown Atlanta. The space will be home to both the Society's International Headquarters, which is moving from its existing campus near Emory University, and its South Atlantic Division office, which is currently located at Lenox Park. The agreement brings Inforum to 98 percent leased.

"Practically any part of metro Atlanta would have been thrilled to land the American Cancer Society. The competition among submarkets was fierce," said Larry Gellerstedt, president of Cousins' Office/Multi-family Division. "We were proud to put together a mutually attractive package that brought this tremendous organization to downtown Atlanta. It's yet another sign that downtown is headed in the right direction."

John Shlesinger, Sam Holmes and Anne Lofye of CB Richard Ellis represented the Society, and Walter Fish and Scott Rees of Cousins represented the landlord in the transaction.

The Society lease is Cousins' second major downtown Atlanta announcement in as many weeks. On Aug. 3, the company announced it agreed to purchase One Ninety One Peachtree Tower and plans to relocate its headquarters to the downtown building during the first half of 2007.
