Filed by BancorpSouth, Inc. pursuant to Rule 425 under the Securities Act of 1933. Subject Company: BancorpSouth, Inc. Commission File No.: 1-12991 THE FOLLOWING IS A JOINT PRESS RELEASE ISSUED BY BANCORPSOUTH AND PINNACLE BANCSHARES. PRESS RELEASE BANCORPSOUTH AND PINNACLE BANCSHARES ANNOUNCE MERGER AGREEMENT LITTLE ROCK, Ark. and TUPELO, Miss., Nov. 15 -- BancorpSouth, Inc. (NYSE: BXS) and Pinnacle Bancshares, Inc. announced today the signing of a definitive agreement for the merger of their respective companies. The transaction is expected to be completed by the end of the first quarter of 2002. Approval of banking regulators and Pinnacle Bancshares shareholders is required. Terms of the financial transaction were not disclosed. Stephens Inc. is acting as Pinnacle Bancshare's financial advisor. Pinnacle Bancshares is an Arkansas business corporation that owns all of the stock of the $130 million asset Pinnacle Bank. The bank operates two full-service banking locations in the Little Rock market. Pinnacle President and CEO Bob Althoff, a veteran Arkansas banker said, "Our merger with BancorpSouth gives us the needed capital capacity to continue our rapid growth in the Little Rock metropolitan market. We have experienced tremendous acceptance in this market. However, to continue to meet our customer's expectations and expanding needs we realized we must join with a company with a similar operating philosophy, strong capital and with expanded resources and technological capabilities. With BancorpSouth we have found that partner. Through this partnership we will add greater value to our business clients through a higher level and greater sophistication of service. We are excited about the prospects this partnership brings." BancorpSouth Chairman and CEO Aubrey B. Patterson said, "We are pleased to have Pinnacle joining our banking family. Only 15 months ago BancorpSouth and First United Bancshares of El Dorado merged, making our company a six-state, $9.4 billion financial services company. Although we serve numerous Arkansas markets, we had no presence in Little Rock, the state's largest market. We are pleased to be coming to Little Rock with the opportunity Pinnacle and their exemplary staff provide us. Successful merger integration has always been a strong point for BancorpSouth, and we expect a smooth transition without adverse customer impact." BancorpSouth President and COO James V. Kelley said, "I have watched the development of Pinnacle Bank since its inception five years ago and have been an admirer of their senior management team for years. Merging our two companies is a real opportunity for both of us. This is not our first investment in the state of Arkansas and we don't believe it will be our last." The combined company would have assets of approximately $9.5 billion, deposits of $7.9 billion. Headquartered in Tupelo, Miss., BancorpSouth is a bank holding company with $9.4 billion in assets operating 246 banking and mortgage locations and 233 ATMs in Arkansas, Alabama, Louisiana, Mississippi, Tennessee and Texas communities. The Company also provides investment services through its subsidiary, BancorpSouth Investment Services, Inc., and insurance services through BancorpSouth Insurance Services. BancorpSouth's common stock is traded on the New York Stock Exchange under the symbol BXS.
