        <footnote id="F1">Pursuant to the Agreement and Plan of Merger, dated as of February 24, 2015 (the &quot;Merger Agreement&quot;), each share of Oneida Financial Corp. stock held by the reporting person was converted into and became exchangeable for shares of Community Bank System, Inc. common stock.  Under the terms of the Merger Agreement, and subject to the allocation and proration procedures set forth therein, for each share of Oneida Financial common stock, the reporting person could elect to receive either (a) cash at the rate of $20.00 per share, (b) 0.5635 shares of Community Bank System, Inc. common stock, or (c) a combination of 60% Community Bank System, Inc. common stock and 40% cash, using the same 0.5635 exchange ratio and $20.00 per share cash price.  At this time, the final merger consideration allocation and proration results for the reporting person's Oneida Financial Corp. shares are not available.  Set forth above is the reporting person's estimate of the number of shares of Community Bank System, Inc. stock beneficially owned by the reporting person based upon the allocation and proration procedures set forth in the Merger Agreement.  The reporting person will file an amended Form 3 once the final stock ownership numbers are available.</footnote>
