Dear Customer:

On October 25, 2010, the Wilber Corporation and Community Bank System, Inc. announced the signing of a definitive agreement in which the Wilber Corporation, parent company of Wilber National Bank, will merge with Community Bank System, Inc.

The merger of Wilber’s 22 offices with Community’s 150 customer facilities (generally in smaller communities in New York and Pennsylvania), will combine two institutions with a strong history of customer-focused service. The combined branch network of our two institutions will expand our customer facilities across western and northern New York and down the Route 81 corridor to Scranton and Wilkes Barre, Pennsylvania.

Both Wilber and Community share a similar “community banking” philosophy with a focus on the local communities and local decision-making. The Wilber name will be changed to Community Bank, N.A. following satisfaction of closing conditions and completion of the merger, which is anticipated early in the second quarter of 2011. However, our commitment to providing the highest level of customer service will continue unchanged.

Historically, Community Bank, N.A. has been ranked as one of the top ten banks in the nation for customer satisfaction by J.D. Powers and Associates and was ranked in 2010 as one of the top ten banks in the country for financial strength by Forbes Magazine.

The goal of Wilber National Bank and Community Bank, N.A. is to make the transition as seamless as possible for customers. We’re pleased to let you know that no Wilber offices will be closed as a result of the merger. In fact, Wilber customers will benefit from a wider range of products and services as well as an expanded network of branches and ATMs.

Our commitment to serving our local communities will continue now and into the future with a team approach and focus on community banking. We encourage you to continue to look to your Wilber banking team for all your financial needs and questions whether it’s for consumer loans, mortgages, business loans, deposit services, as well as our trust and investment services.

Over the upcoming months, we will provide you with more detailed information. In the meantime, call Wilber National Bank at 800-374-7980 or stop by any Wilber office if you have questions. To learn more about Community Bank, please visit www.communitybankna.com.

Again, we look forward to continuing to serve your banking needs and our communities, and we are extremely excited to continue our relationship with you. Together we are working closely to make this a pleasant and smooth transition.

Sincerely,



/s/ Joseph E. Sutaris	/s/ Mark E. Tryniski
