News Release Date: April 18, 1997 Contact: Katherine Taylor 815-961-7164 AMCORE BANK LOGO AMCORE FINANCIAL, INC., COMPLETES ACQUISITION OF FIRST NATIONAL BANCORP, MONROE, WISCONSIN ROCKFORD, IL - AMCORE Financial, Inc. today took a major step toward becoming a regional financial institution. The acquisition of First National Bancorp of Monroe, Wis., was completed taking AMCORE across state lines for the first time. "This truly is a historic moment for AMCORE," says Robert J. Meuleman, president and chief executive officer. "We now officially are a multi-state financial institution." First National Bancorp has assets of approximately $215 million. The acquisition brings AMCORE's assets to over $3 billion. AMCORE issued 1,881,524 shares of its stock in exchange for all of First National's 249,539 common shares outstanding. First National Bancorp owns the First National Bank and Trust of Monroe. First National has 105 employees and five offices in southern Wisconsin, including Monroe, New Glarus, Belleville and two in Madison. Monroe is 50 miles from Rockford. AMCORE will record during the second quarter an after tax charge of about a $1.3 million, or eight cents per share, for expenses related to the merger. Last year, First National earned nearly $2.8 million. "This is a well run bank with a strong management team," says Meuleman. "Its culture is similar to AMCORE's, so this will be a good fit for both organizations." Meuleman says AMCORE offers the communities it serves the resources of a large bank, yet encourages its affiliates to retain their local autonomy and community commitment. Both banks follow the community banking philosophy. "Our goal is to offer our customers a broad range of products and services so we can meet their financial needs better than any of our competitors," he says. AMCORE Bank N.A.
