First Business Bank Ranks High in National List of Top Community Banks

MADISON, January 29, 2004 - First Business Bank was recognized as one of the top 100 community banks nationally by American Banker in January’s "Community Banks with Largest Commercial and Industrial Loan Portfolios" report.

The study was performed by Sheshunoff Information Services, a division of Thomson Corp. All banks were ranked by commercial and industrial loan amounts outstanding on September 30, 2003. Only three other Wisconsin community banks made the top 100 list. First Business Bank was the only Madison area bank to receive this recognition.

"We are honored to be recognized among top national community banks by American Banker," stated Corey Chambas, President and CEO of First Business Bank. "In today’s era of megabanks and nationwide branching, business people find increased value in local, accessible customer service and the individual attention they receive at community banks."
