assumptions about modest revenue enhancements. We anticipate the transaction will close during the fourth quarter of 2003, pending approval by GRGN shareholders and customary regulatory approval.”

Mr. Belden went on to say, “We are delighted to enhance our Pennsylvania presence with the acquisition of Grange National Banc Corp., with its peer-leading track record of earnings growth, loan generation and consistently superior asset quality. We are especially pleased that Tom McCullough, who has led Grange and its strong performance since 1990, will join our senior management team as President, Pennsylvania Banking. His 35 years of banking experience make him ideally suited to take responsibility for all our Pennsylvania banking business. Grange customers will benefit from CBU’s greater array of financial products and services while continuing to be served by familiar staff in each branch. Furthermore, all our Pennsylvania customers will benefit from our expanded market coverage that will offer retail branches in the Bradford, Lackawanna, Luzerne, Susquehanna and Wyoming counties of Northeastern Pennsylvania.”
