EXHIBIT A

VOTING AGREEMENT

This Voting Agreement, dated as of February 24, 2015 (this “Agreement”), is by and between Community Bank System, Inc., a Delaware corporation (“CBSI”), and the undersigned shareholder (the “Shareholder”) of Oneida Financial Corp., a Maryland corporation (“Oneida”).

RECITALS

A.           Concurrently with the execution of this Agreement, CBSI and Oneida entered into an Agreement and Plan of Merger (the “Merger Agreement”) which provides for the merger of Oneida with and into CBSI (the “Merger”). Pursuant to the Merger, shares of capital stock of Oneida will be converted into the merger consideration, consisting of cash and shares of common stock of CBSI, on the basis set forth in the Merger Agreement.

B.           The Shareholder has the legal power to vote, or to direct the voting of (by law, contract or otherwise), the shares of the outstanding common stock of Oneida indicated on the final page of this Agreement (the “Shares”).

C.           As a material inducement to enter into the Merger Agreement, CBSI desires the Shareholder to agree, and the Shareholder is willing to agree, to vote or cause to be voted, as the case may be, the Shares and any other such shares of capital stock of Oneida subsequently acquired by the Shareholder so as to facilitate consummation of the Merger as provided in this Agreement.

NOW, THEREFORE, intending to be legally bound, the parties agree as follows:

1.           Agreement to Vote Shares; Additional Purchases.

1.1           Agreement to Vote Shares. At every meeting of the shareholders of Oneida called with respect to the approval of the Merger Agreement and/or the Merger, and at every adjournment thereof, and on every action or approval by written consent of the shareholders of Oneida with respect to the approval of the Merger Agreement and/or the Merger, the Shareholder shall vote, or cause to be voted, the Shares and any New Shares (as defined below) in favor of adoption and approval of the Merger Agreement and the Merger.

1.2           Agreement to Retain Shares. The Shareholder shall not transfer, sell, exchange, pledge or otherwise dispose of or encumber the Shares or any New Shares; provided, however, that the Shareholder may transfer the Shares if the transferee, prior to such transfer, executes a voting agreement with respect to the Shares to be transferred, substantially in the form of this Agreement, and provides such executed agreement to CBSI.

1.3           Additional Purchases. The Shareholder agrees that any shares of capital stock of Oneida that the Shareholder purchases or with respect to which the Shareholder otherwise acquires the power to vote, or to direct the voting (“New Shares”), after the execution

of this Agreement and prior to the Expiration Date (as defined below) shall be subject to the terms and conditions of this Agreement to the same extent as if they constituted Shares.

2.           Representations and Warranties of the Shareholder. The Shareholder (i) has the legal power and authority to vote, or to direct the voting of, the Shares, which at the date hereof are (except to the extent set forth in a schedule delivered herewith) free and clear of any liens, options, security interests or other similar encumbrances; (ii) does not possess the right to vote, or to direct the voting of, as the date hereof, any shares of capital stock of Oneida other than the Shares; and (iii) has full power and authority to make, enter into and carry out the terms of this Agreement.

3.           Proxy. The Shareholder hereby covenants and agrees to execute and deliver a proxy to be tendered at every meeting of Oneida shareholders called with respect to the approval of the Merger Agreement and/or the Merger, in the reasonable opinion of CBSI, to carry out the purpose of this Agreement.

4.           Termination. This Agreement shall terminate and shall have no further force or effect as of the earlier to occur of (i) such date and time as the Merger shall become effective in accordance with the terms and provisions of the Merger Agreement, or (ii) such date and time as the Merger Agreement shall have been terminated pursuant to Article VII thereof (the “Expiration Date”).

5.            Fiduciary Duties. If the Shareholder is a Director of Oneida, nothing in this Agreement shall be construed to prevent the Shareholder from exercising his/her fiduciary obligations as a Director of Oneida in the event of a Superior Proposal as set forth in the Merger Agreement, provided that the Shareholder, in his/her capacity as a shareholder of Oneida, shall remain obligated to comply with Shareholder’s obligations in this Agreement.

6.           Miscellaneous.

6.1           Severability. If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction to be invalid, void or unenforceable, then the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated.

6.2           Binding Effect and Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns, but, except as otherwise specifically provided herein, neither this Agreement nor any of the rights, interests or obligations of the parties hereto may be assigned by any of the parties without prior written consent of the other parties.

6.3           Amendments and Modification. This Agreement may not be modified, amended, altered or supplemented except upon the execution and delivery of a written agreement executed by the parties hereto.

6.4           Specific Performance; Injunctive Relief. The parties hereto acknowledge that CBSI will be irreparably harmed and that there will be no adequate remedy at law for a violation of any of the covenants or agreements of the Shareholder set forth herein. Therefore, it is agreed that, in addition to any other remedies that may be available to CBSI upon any such violation, CBSI shall have the right to enforce such covenants and agreements by specific performance, injunctive relief or by any other means available to CBSI at law or in equity.
