The Golub/Investcorp bought the 41-acre property, which also includes two garages, in February 2004 for $60.2 million, sources say. Michael Newman, president and CEO of Golub, tells GlobeSt.com that they believe in the buildings. "We spent a lot of time and effort on the property," he says. "When we took it over the occupancy was in the high 60% range, and we've taken it to 93%. We think it's the best building in the market. It's very recognizable, is very stable and has nice amenities." Golub will continue to manage the building.

Building tenants include Northrup Grumman, Travelers Insurance and Healthways, and retail shops such as Dierdorf & Hart's Steak House, Coldstone Creamery and Panera Bread. Lease rates at the building, about 30 years old, are in the mid-$20 range per sf, Newman says.

He says Investcorp felt it had been owner long enough in a building that had reached a high lease point. "The profit fit in with their plan," Newman says. "The sales market was decent enough for them to go. We think there's still an upside to go, we think we can bring the project to another level."
