Community Bank System Completes Merger with The Wilber Corporation

SYRACUSE, N.Y.--(BUSINESS WIRE)--Community Bank System, Inc. (NYSE: CBU) announced that it completed its merger with The Wilber Corporation, and its banking subsidiary, Wilber National Bank, a $870 million commercial bank with 22 banking offices serving the Central Region of Upstate New York. As a combined financial institution, the Company will have approximately $6.3 billion in assets and $4.6 billion in deposits, and expand into seven new counties covering the Central Leatherstocking, Greater Capital District and Catskills regions of Upstate New York.

Mark E. Tryniski, President and Chief Executive Officer of Community Bank System commented, “We are excited to be partnering with Wilber National Bank to extend our Upstate New York service area. Wilber has a significant market presence and attractive deposit share in contiguous regions, with demographic characteristics very similar to our current markets. In addition, Wilber Bank has an impressive history of service to its customers and its communities, a tradition that aligns well with that of Community Bank. We are extremely pleased to welcome Wilber’s customers, shareholders and employees to Community Bank.”

Stock Election Process

On or about April 13, 2011, Community Bank System will distribute election forms to all the Wilber shareholders of record as of the close of business on April 8, 2011 in order for each shareholder to elect the form of merger consideration. Subject to the allocation procedures set forth in the merger agreement, the Wilber shareholders can elect to receive all cash, all stock or a combination of 20% cash and 80% stock in exchange for their Wilber shares. The election form must be received by American Stock Transfer & Trust Company, LLC, before the election deadline of May 4, 2011 at 5:00 PM. The merger consideration will not be distributed to the Wilber shareholders until after expiration of the election deadline. If the election deadline is extended, Community Bank System will issue a press release setting forth the new election deadline. Assuming that the deadline is not extended, the Wilber shareholders should expect to receive their merger consideration on or after May 13, 2011. Wilber shareholders who hold any of their Wilber stock in “street name” (i.e., through a broker, bank or other nominee) will receive separate election instructions from their broker, bank or other nominee. Those shareholders must follow the election instructions received from the broker, bank or other nominee in order to make a valid election for all of their Wilber stock. Because only the registered holders of Wilber common stock can make an election as to the form of merger consideration, any election by a Wilber shareholder who holds shares in “street name” must be made through the broker, bank or other nominee. Community Bank System has engaged Phoenix Advisory Partners to assist shareholders in completing their election forms. Shareholders can contact Phoenix toll free at 877-478-5038 with any questions about completing the election forms.
