Baton Rouge is a dynamic market, and joining with BancorpSouth will allow us to provide more sophisticated banking services to our current and prospective customers. We have experienced remarkable acceptance in this market. However, to continue to meet our customers' expectations and expanding needs, we realized we must join with a complete financial services company that offers expanded resources and technological capabilities." Business Holding Corporation Chairman David Pitts said, "This merger is mutually beneficial both for our bank and BancorpSouth. Through this merger we obtain the strength of one of the leading banks in the MidSouth, and that benefits our customers. BancorpSouth now has the opportunity to enter the Baton Rouge banking market with a staff of seasoned Louisiana bankers already in place." BancorpSouth Chairman and CEO Aubrey B. Patterson said, "The Business Bank of Baton Rouge has grown by providing unparalleled specialized service through professional relationships. Our partnership will enhance their ability to serve the complete needs of their customers providing a real opportunity for both companies.

We believe BancorpSouth's brand of banking will be extremely popular in Baton Rouge." BancorpSouth President and COO James V. Kelley said, "We are pleased to have The Business Bank of Baton Rouge joining our banking family. This outstanding commercial bank will expand our Louisiana banking family, which currently includes 13 banking locations in Shreveport, Bossier City, Monroe, West Monroe, Rayville and Ruston, with more than $468 million in deposits."

More than a year into our relationship with BancorpSouth this is truly a win-win situation for Wright & Percy and our customers and similarly will be for the customers of The Business Bank of Baton Rouge.
