Other Events. On June 19, 2001, NBT Bancorp Inc., a Delaware corporation ("NBT"), and CNB Financial Corp., a New York corporation ("CNB"), announced that they had entered into an Agreement and Plan of Merger, dated as of June 19, 2001 (the "Merger Agreement"). Pursuant to the Merger Agreement, CNB and NBT will merge (the "Merger"), with NBT being the surviving corporation, to create a holding company with assets of $3.5 billion. Stockholders of CNB will receive 1.2 shares of NBT common stock for each share exchanged. Based on the June 18, 2001, closing price of NBT common stock on the Nasdaq National Market, the transaction is valued at $140 million or $18.30 per share for the outstanding common stock of CNB. The Merger, which has been unanimously approved by the boards of directors of NBT and CNB, is subject to the approval of each company's stockholders and of banking regulators. The Merger is expected to close in the fourth quarter of 2001 and is intended to be accounted for as a pooling-of-interests and to qualify as a tax-free exchange for CNB stockholders. CNB has provided NBT an option to acquire a number of shares of CNB's common stock equal to 2.9% of CNB's common stock outstanding as of the first date the option becomes exercisable. The option is exercisable in the event of certain circumstances involving transactions with third parties, acts of third parties, or break-up of the Merger Agreement. The combined company will have a 15-seat board of directors which will be made up of twelve current directors of NBT and three from CNB. Common stockholders of NBT will have ownership of approximately 73 percent of the combined company while CNB's common stockholders will own approximately 27 percent. Simultaneously with the Merger, CNB's principal banking subsidiary, Central National Bank, Canajoharie, will merge with and into NBT Bank, N.A., NBT's principal banking subsidiary, with NBT Bank being the surviving bank in the bank merger.
