The $2.5-billion bank with 11 branches in the market will use the space, which covers more than four floors, as its headquarters. "The selection of this space, located in the heart of our market, gives us a tremendous opportunity to improve upon our processes and, in turn, better serve our customers," says chairman Jeffrey W. Taylor in a statement.

Occupancy at Pointe O'Hare increases to 60% with the lease.

The bank, which caters to small to mid-sized businesses, has five locations in Chicago, two in north suburban Skokie and one in Wheeling. The company currently is headquartered at 350 E. Dundee Rd. in that north suburb. It also has a west suburban presence in Broadview and Lombard as well as in southwest suburban Burbank.
