(iii) At the option of each holder of Oneida Common Stock, sixty percent (60%) of such holder’s aggregate number of shares of Oneida Common Stock (the “Stock Portion”) shall be converted into the right to receive such number of shares of CBSI Common Stock equal to the number of shares of Oneida Common Stock in the Stock Portion multiplied by the Exchange Ratio, and forty percent (40%) of such holder’s aggregate number of shares of Oneida Common Stock (the “Cash Portion”) shall be converted into the right to receive cash (payable by check) in an amount equal to the number of shares of Oneida Common Stock in the Cash Portion multiplied by $20.00 (such election, the “Mixed Election” and such shares, the “Mixed Election Shares”), provided that:

(A) Fractional shares will not be issued and cash (payable by check) will be paid in lieu thereof as provided in Section 2.2(j); and

(B) After giving effect to Section 2.2(a)(i), (ii) and (iii), in no event shall, in the aggregate, more than sixty percent (60%) of Oneida Common Stock issued and outstanding immediately prior to the Effective Time be converted into and become shares of CBSI Common Stock;

(C) After giving effect to Section 2.2(a)(i), (ii), and (iii), in no event shall, in the aggregate, more than forty percent (40%) of Oneida Common Stock issued and outstanding immediately prior to the Effective Time be converted into and become cash; or

(iv) If the holder of Oneida Common Stock indicates on the Election Form that such record holder has no preference as to the receipt of cash or CBSI Common Stock for such shares, or if no election is validly made by a holder by the Election Deadline pursuant to Section 2.2(d) (“Non-election Shares”), all of such holder’s shares of Oneida Common Stock shall be converted into the right to receive CBSI Common Stock as set forth in Section 2.2(a)(i), cash as set forth in Section 2.2(a)(ii), or any combination of CBSI Common Stock and cash as determined by CBSI; provided, however, that no fractional shares shall be issued and cash will be paid in lieu thereof as provided in Section 2.2(j). Prior to any allocation of Cash Election Shares, Stock Election Shares or Mixed Election Shares pursuant to Section 2.2(f) and (g), such Non-election Shares of Oneida Common Stock shall be allocated by CBSI on a pro rata basis among non-electing holders based upon the number of shares of Oneida Common Stock for which an election has not been received by the Election Deadline in order to achieve the overall ratio of sixty percent (60%) of Oneida Common Stock to be converted into CBSI Common Stock

and forty percent (40%) of Oneida Common Stock to be converted into cash. Notice of such allocation shall be provided promptly to each holder of Non-election Shares whose shares of Oneida Common Stock are allocated pursuant to this Section 2.2(a)(iv).

(b) Treasury Shares and Shares Held by CBSI. There are no shares of Oneida Common Stock or Preferred Stock held in treasury by Oneida. Each share of Oneida Common Stock owned by any Subsidiary of Oneida, CBSI or any Subsidiary of CBSI (in each case other than in a fiduciary capacity) immediately prior to the Effective Time shall be cancelled without any conversion thereof and no payment or distribution shall be made with respect thereto.

(c) Procedures for Election. CBSI shall prepare an election form and other appropriate and customary transmittal materials in such form as is reasonably acceptable to Oneida (the “Election Form”) which shall be mailed to Oneida’s shareholders of record five (5) business days prior to the mailing date so as to permit Oneida’s shareholders to exercise their right to validly elect the form of Merger Consideration (the “Election”) set forth in Section 2.2(a) prior to the Election Deadline, subject to the allocation and election procedures set forth in this Section 2.2. CBSI shall mail the Election Form no later than twenty (20) days prior to the Election Deadline, and shall use reasonable efforts to make available as promptly as possible a duplicate Election Form to any shareholder of Oneida who requests such Election Form following the initial mailing of the Election Forms and prior to the Election Deadline. As used herein, “Election Deadline” means 5:00 p.m. on the date selected by CBSI as the last day on which Election Forms may be validly returned by Oneida shareholders, which day shall be not less than twenty (20) days after the initial mailing of the Election Forms and be no later than five (5) days prior to the Closing Date.

(d) Perfection of the Election. Any Election shall have been made properly only if the Exchange Agent shall have received by 5:00 p.m. local time in the city in which the principal office of such Exchange Agent is located, on the date of the Election Deadline, an Election Form properly completed and signed and accompanied by certificates of the shares of Oneida Common Stock to which such Election Form applies or by an appropriate customary guarantee of delivery of such certificates, as set forth in such Election Form, from a member of any registered national securities exchange or a commercial bank or trust company in the United States; provided, that such certificates are in fact delivered to the Exchange Agent by the time required in such guarantee of delivery. Failure to deliver shares of Oneida Common Stock covered by such a guarantee of delivery within the time set forth on such guarantee shall be deemed to invalidate any otherwise properly made Election, unless otherwise determined by CBSI, in its sole discretion. Oneida and CBSI shall cooperate to issue a press release reasonably satisfactory to each of them announcing the date of the Election Deadline not more than fifteen (15) business days before, and at least five (5) business days prior to, the Election Deadline.

(e) Withdrawal of Shares. Any holder of Oneida Common Stock may at any time prior to the Election Deadline revoke the holder’s election and either (i) submit a new Election Form in accordance with the procedures in Section 2.2(d), or (ii) withdraw the certificate(s) for Oneida Common Stock deposited therewith by providing written notice that is received by the Exchange Agent by 5:00 p.m., local time for the Exchange Agent, on the Election Deadline. In the event of the termination of this Agreement, the Exchange Agent shall

return any certificates deposited by the holder of Oneida Common Stock to such holder at the address and to the Person set forth in the Election Form.

(f) Reduction of Shares Deposited for Cash. If more than forty percent (40%) of the total number of shares of Oneida Common Stock issued and outstanding at the Election Deadline, have been deposited for exchange with cash pursuant to the All Cash Election and/or the Mixed Election and not withdrawn pursuant to Section 2.2(e), CBSI will cause to be eliminated by the Exchange Agent, from the shares deposited pursuant to the All Cash Election (subject to the limitations described in Section 2.2(f)(iv)), a sufficient number of such shares so that the total number of shares remaining on deposit for exchange into cash pursuant to the All Cash Election and the Mixed Election does not exceed forty percent (40%) of the shares of Oneida Common Stock issued and outstanding on the Election Deadline. The holders of Oneida Common Stock who have made the Mixed Election shall not be required to have more than sixty percent (60%) of their shares of Oneida Common Stock converted into CBSI Common Stock. After giving effect to Section 2.2(a)(iv), such elimination will be effected as follows:

(i) Subject to the limitations described in Section 2.2(f)(iv), CBSI will eliminate or cause to be eliminated from the shares deposited pursuant to the All Cash Election, and will add or cause to be added to the shares deposited for CBSI Common Stock pursuant to the All Stock Election, on a pro rata basis in relation to the total number of shares deposited pursuant to the All Cash Election minus the number of shares so deposited by the holders described in Section 2.2(f)(iv), such number of whole shares of Oneida Common Stock on deposit for cash pursuant to the All Cash Election as may be necessary so that the total number of shares remaining on deposit for cash pursuant to the All Cash Election or the Mixed Election is equal, as nearly as practicable, to forty percent (40%) of the shares of Oneida Common Stock issued and outstanding immediately prior to the Effective Time;

(ii) All shares of Oneida Common Stock that are eliminated pursuant to Section 2.2(f)(i) from the shares deposited for cash pursuant to All Cash Election shall be converted into CBSI Common Stock as provided by Section 2.2(a)(i);

(iii) Notice of such allocation shall be provided by CBSI or the Exchange Agent promptly after the Election Deadline to each holder whose shares of Oneida Common Stock are eliminated from the shares on deposit for exchange with cash pursuant to Section 2.2(f)(i); and

(iv) Notwithstanding the foregoing, the holders of one hundred (100) or fewer shares of Oneida Common Stock of record on the date of this Agreement who have elected the All Cash Election shall not be required to have any of their shares of Oneida Common Stock converted into CBSI Common Stock.

(g) Increase of Shares Deposited for Cash. If fewer than forty percent (40%) of the total number of shares of Oneida Common Stock issued and outstanding have, at the Election Deadline, been deposited for cash pursuant to the All Cash Election and/or the Mixed Election and not withdrawn pursuant to Section 2.2(e), CBSI will promptly add, or cause to be added by the Exchange Agent, to such deposited shares, a sufficient number of shares of Oneida Common Stock deposited for shares of CBSI Common Stock pursuant to the All Stock Election

so that the total number of shares of Oneida Common Stock on deposit for cash pursuant to the All Cash Election and the Mixed Election immediately prior to the Effective Time is not less than forty percent (40%) of the shares of Oneida Common Stock issued and outstanding immediately prior to the Effective Time. The holders of Oneida Common Stock who have elected to have their shares converted pursuant to the Mixed Election shall not be required to have more than forty percent (40%) of their shares of Oneida Common Stock converted into cash. After giving effect to Section 2.2(a)(iv), such addition will be effected as follows:

(i) CBSI will cause to be added to the shares deposited for cash pursuant to the All Cash Election or the Mixed Election, and will eliminate or cause to be eliminated from the shares deposited for CBSI Common Stock pursuant to the All Stock Election, on a pro rata basis in relation to the total number of shares of Oneida Common Stock deposited for shares of CBSI Common Stock pursuant to the All Stock Election, such number of whole shares of Oneida Common Stock not then on deposit for cash as may be necessary so that the number of shares remaining on deposit for exchange with cash is equal, as nearly as practicable, to forty percent (40%) of the shares of Oneida Common Stock issued and outstanding immediately prior to the Effective Time;

(ii) All shares of Oneida Common Stock that are added pursuant to Section 2.2(g)(i) to the shares deposited for cash shall be converted into cash as provided by Section 2.2(a)(ii); and

(iii) Notice of such allocation shall be provided by CBSI or the Exchange Agent promptly after the Election Deadline to each holder whose shares of Oneida Common Stock are added to the shares on deposit for cash pursuant to Section 2.2(g)(i).

(h) CBSI Common Stock. Each share of CBSI Common Stock outstanding immediately prior to the Effective Time shall remain unchanged and shall constitute the common stock of the Surviving Corporation.

(i) Adjustments to Exchange Ratio. If, subsequent to the date of this Agreement but prior to the Effective Time, the outstanding shares of CBSI Common Stock or Oneida Common Stock shall be increased, decreased, changed into or exchanged for a different number of shares, in each case by reason of any stock split, recapitalization, or reclassification or other similar change, the Exchange Ratio shall be adjusted proportionately.

(j) Fractional Shares. No certificates or scrip representing less than one share of CBSI Common Stock shall be issued upon the surrender for exchange of a certificate or certificates which immediately prior to the Effective Time represented outstanding shares of Oneida Common Stock. In lieu of any such fractional share, each holder of such shares who would otherwise have been entitled to a fraction of a share of CBSI Common Stock, upon surrender of certificates representing shares of Oneida Common Stock for exchange, shall be paid upon such surrender cash (without interest) in an amount equal to such fraction multiplied by $20.00.

(k) Oneida Options. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any

Person, each Oneida Option which is outstanding, unexpired and unexercised immediately prior to the Effective Time, whether or not previously vested and exercisable, shall be cancelled and the holder thereof shall receive, no later than the first payroll payment date after the Effective Time, a cash payment equal to the product obtained by multiplying (i) the aggregate number of shares of Oneida Common Stock that were issuable upon the exercise of such Oneida Option and (ii) $20.00, less any exercise price payable pursuant to such Oneida Option, without interest, less any required withholdings (the “Option Consideration”). In the event any Oneida Option is subject to Section 409A of the Code, the payment of the Option Consideration shall be delayed to the extent necessary to comply with Section 409A of the Code.

(l) Oneida Stock Awards. Subject to the provisions of this Agreement, at the Effective Time, automatically by virtue of the Merger and without any action on the part of any Person, each restricted stock award issued pursuant to Oneida’s 2012 Equity Incentive Plan (“Oneida Restricted Stock”) that is outstanding immediately prior to the Effective Time shall vest in full and the restrictions thereon shall lapse, and, as of the Effective Time, each such share of Oneida Common Stock shall be entitled to receive the Merger Consideration in accordance with Section 2.2.

2.3. Effect of Merger.

Upon the Effective Time of the Merger:

(a) The certificate of incorporation and bylaws of CBSI, each as in effect immediately prior to the Effective Time, shall be the certificate of incorporation and bylaws, respectively, of the Surviving Corporation, in each case until amended in accordance with the DGCL.

(b) All respective assets, rights, franchises, and interest of Oneida and CBSI in and to every type of property shall be vested in the Surviving Corporation by virtue of the Merger without any deed or other transfer; and the Surviving Corporation, without any order or other action on the part of any court or otherwise, shall hold and enjoy all rights of property, franchises and interest, in the same manner and to the same extent as such rights, franchises and interests were held and enjoyed by Oneida and CBSI immediately prior to the Effective Time.

(c) The Surviving Corporation shall be liable for all of the liabilities of Oneida and CBSI and shall be bound by and subject to all of the obligations and contracts of Oneida and CBSI, provided that nothing in this Agreement shall render the Surviving Corporation liable for a liability or obligation of Oneida, the satisfaction of which is subject to the prior approval or consent of any regulatory authority, unless such regulatory approval or consent has been obtained. All rights of creditors and obligees and all liens on property of Oneida and CBSI shall be preserved and unimpaired.

(d) The directors and officers of CBSI immediately prior to the Effective Time shall be the directors and officers, respectively, of the Surviving Corporation, with the addition of the New Directors pursuant to Section 5.9(f).

2.4. Procedure to Exchange Shares.

(a) At or prior to the Effective Time, CBSI shall cause to be deposited with American Stock Transfer & Trust Company or another financial institution experienced in serving as an exchange agent for a public company merger (the “Exchange Agent”), for exchange in accordance with this Article II, the aggregate number of shares of CBSI Common Stock, cash, by wire transfer of immediately available funds, into which the outstanding shares of Oneida Common Stock shall be converted pursuant to Section 2.2 of this Agreement and an estimated amount of cash, by wire transfer of immediately available funds, into which any fractional shares of Oneida Common Stock shall be converted pursuant to Section 2.2(j). As soon as practical after the Effective Time, but no later than five (5) business days after the Effective Time, CBSI shall cause the Exchange Agent to mail to each holder of record of Oneida Common Stock who theretofore has not submitted such holder’s shares of Oneida Common Stock with an Election Form, a letter of transmittal in customary form specifying the procedures for delivery of such holders’ shares of Oneida Common Stock to the Exchange Agent in exchange for the Merger Consideration and cash in lieu of fractional shares issuable pursuant to this Article II. Upon surrender to the Exchange Agent of its shares of Oneida Common Stock in the manner set forth in the letter of transmittal, accompanied by a properly completed letter of transmittal, a holder of Oneida Common Stock will be entitled to receive the Merger Consideration promptly after the Effective Time, determined as provided in Section 2.2. Until so surrendered, each share of Oneida Common Stock shall represent after the Effective Time, for all purposes, only the right to receive, without interest, the applicable Merger Consideration and any cash in lieu of fractional shares of CBSI Common Stock to be issued or paid in consideration therefor upon surrender of such share of Oneida Common Stock in accordance with this Article II.

(b) No dividends or other distributions declared after the Effective Time with respect to CBSI Common Stock shall be paid to the holder of any unsurrendered share of Oneida Common Stock until such holder shall surrender such certificate in accordance with this Agreement. After the surrender of a share of Oneida Common Stock in accordance with this Agreement, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore have become payable with respect to shares of CBSI Common Stock.

(c) At the Effective Time, the stock transfer books of Oneida shall be closed and no transfer of Oneida Common Stock shall thereafter be made or recognized. If, after the Effective Time, shares of Oneida Common Stock are presented for transfer, they shall be cancelled and exchanged for the Merger Consideration as provided in this Section 2.4.

(d) In the event any certificate evidencing shares of Oneida Common Stock shall have been lost, stolen, destroyed or mutilated, upon the making of an affidavit of that fact by the Person claiming such certificate to be lost, stolen, destroyed or mutilated and, if required by CBSI, the making of an indemnity agreement in a form reasonably requested by CBSI and/or the posting by such Person of a bond in such amount as CBSI may reasonably direct as indemnity against any claim that may be made against it with respect to such certificate, the Exchange Agent will issue in exchange for such lost, stolen, destroyed or mutilated certificate the Merger Consideration deliverable in respect thereof pursuant to this Agreement.

(e) Neither CBSI nor Oneida shall be liable to any holder of shares of Oneida Common Stock for any Merger Consideration delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. After the first anniversary of the Effective Time, CBSI shall be entitled to instruct the Exchange Agent to release to CBSI all of the shares of CBSI Common Stock and cash then remaining undistributed to former shareholders of Oneida. Thereafter, CBSI shall deliver the appropriate number of shares of CBSI Common Stock and/or a check for cash in lieu of fractional shares, if any, from time to time, as shares of Oneida Common Stock, the accompanying letter of transmittal and other related documents are presented to the Exchange Agent or CBSI, until at such time as such shares and cash are delivered to a public official pursuant to any applicable abandoned property, escheat or similar law.

2.5. Tax Treatment. The parties hereto intend that the Merger qualify as a tax-free reorganization under Section 368(a) of the Code and that this Agreement shall constitute a plan of reorganization as that term is used in Sections 354 and 361 of the Code.

2.6. Modification of Structure. Upon the mutual written consent of Oneida and CBSI (which consent on the part of Oneida shall not be unreasonably withheld or delayed), or at the request of any regulatory authority, CBSI shall have the right to modify the structure of any of the Transactions, provided that (a) there are no adverse tax consequences to the shareholders of Oneida as a result of such modification, (b) the Merger Consideration is not changed in kind, value or reduced in amount as a result of such modification, and (c) consummation of the Transactions is not likely to be impaired or delayed as a result of such modification.

2.7. Closing. The Closing of the Transactions shall be held at the offices of Bond, Schoeneck & King, PLLC, One Lincoln Center, Syracuse, New York on the fifth business day, or other mutually agreeable time, following satisfaction or waiver of the conditions to consummation of the Merger set forth in Article VI hereof (the “Closing Date”). Alternatively, the parties may agree that the Closing shall occur without their or their counsel’s physical presence in the same location, through the transmission and execution of documents and instruments using electronic media, including, but not limited to, email and facsimile. Digital signatures produced by such means shall have the same force and effect as handwritten signatures. If the parties elect to use this method for the Closing, following the Closing, they shall promptly execute handwritten documents and instruments and exchange the signature pages thereof so that each party shall have a complete set of manually signed documents memorializing the Closing.

ARTICLE III

REPRESENTATIONS AND WARRANTIES OF ONEIDA

Except as Previously Disclosed, Oneida hereby represents and warrants to CBSI as follows:

3.1. Capital Structure of Oneida. The authorized capital stock of Oneida consists of (i) 10,000,000 shares of Preferred Stock, none of which are issued and outstanding and (ii) 30,000,000 shares of Oneida Common Stock, of which 7,025,444 shares are issued and

outstanding, which amount includes 153,000 shares granted pursuant to Oneida Restricted Stock awards. No shares of Oneida Common Stock are held in treasury. Except for (i) 172,348 shares of Oneida Common Stock reserved for issuance upon the exercise of outstanding Oneida Options, (ii) 153,000 shares of Oneida Common Stock subject to outstanding Oneida Restricted Stock awards, there are no outstanding options, warrants, agreements, arrangements, commitments or any similar Rights in existence for the purchase of or issuance of, or which encumber in any way, Oneida Common Stock or any equity interest in any Subsidiary of Oneida. All outstanding shares of Oneida Common Stock have been duly authorized and validly issued and are fully paid and nonassessable. None of the shares of Oneida capital stock has been issued in violation of the preemptive rights of any Person.

3.2. Organization, Standing and Authority of Oneida. Each of Oneida and its Subsidiaries is a duly organized corporation, validly existing and in good standing under the laws of its incorporation with full corporate power and authority to own, lease and operate the properties it purports to own, lease or operate and to carry on its business as now conducted. Each of Oneida and its Subsidiaries is duly licensed or qualified to do business in the states of the United States and foreign jurisdictions where its ownership or leasing of property or the conduct of its business requires such qualification, except where the failure to be so licensed or qualified would not have a Material Adverse Effect on Oneida. Oneida is registered as a savings and loan holding company under the HOLA.

3.3. Ownership of Oneida Subsidiaries; Capital Structure of Oneida Subsidiaries. A true and complete list of all Subsidiaries of Oneida, and each of their respective Subsidiaries, together with the jurisdiction of incorporation of each Subsidiary and the percentage of each Subsidiary’s outstanding capital stock owned by Oneida or another Subsidiary of Oneida, has been Previously Disclosed and Oneida does not, directly or indirectly, own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for, any equity or similar interest in, any other Person.

3.4. Authorized and Effective Agreement.

(a) Oneida has all requisite corporate power and authority to enter into and perform all of its obligations under this Agreement and each of the Transaction Documents to which it is a party. The execution and delivery of this Agreement and the consummation of the Transactions and thereby have been duly and validly authorized by all necessary corporate action in respect thereof on the part of Oneida, except for the affirmative vote of a majority of the issued and outstanding shares of Oneida Common Stock, which is the only shareholder vote required to approve the Merger pursuant to Oneida’s articles of incorporation and bylaws. The Board of Directors of Oneida has approved and adopted this Agreement and the Merger, and directed that this Agreement be submitted to Oneida’s shareholders for approval at a meeting of shareholders to be held as soon as practicable. The Board of Directors of Oneida has unanimously recommended that the shareholders of Oneida approve this Agreement and the Merger. In connection with its approval of this Agreement and the Merger, the Board of Directors of Oneida has received a written fairness opinion dated on or about the date hereof from Keefe Bruyette & Woods, Inc., to the effect that, subject to the terms, limitations, and conditions set forth therein, the Merger Consideration is fair, from a financial point of view, to

the common shareholders of Oneida, which opinion has not been rescinded prior to the execution of this Agreement.

(b) This Agreement and each Transaction Document to which Oneida is a party have been duly executed and delivered by Oneida and, assuming the accuracy of the representation contained in Section 4.3(b) hereof, this Agreement constitutes the legal, valid and binding obligation of Oneida, enforceable against Oneida in accordance with its terms, except that such enforceability may be subject to bankruptcy, insolvency and other laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(c) Except as Previously Disclosed, neither the execution and delivery by Oneida of this Agreement, nor consummation of the Transactions, nor compliance by Oneida with any of the provisions hereof or thereof shall (i) conflict with or result in a breach of any provision of the articles of incorporation or bylaws of Oneida or any of its Subsidiaries, (ii) assuming the consents and approvals contemplated by Section 5.3 hereof and the consents and approvals which are Previously Disclosed are duly obtained, constitute or result in a breach of any term, condition or provision of, or constitute a default under, or give rise to any right of termination, cancellation or acceleration with respect to, or result in the creation of any lien, charge or encumbrance upon any property or asset of Oneida or any of its Subsidiaries pursuant to, any note, bond, mortgage, indenture, license, agreement or other instrument or obligation to which Oneida or any of its Subsidiaries is a party, or (iii) assuming the consents and approvals contemplated by Section 5.3 hereof and the consents and approvals which are Previously Disclosed are duly obtained, conflict with or violate any law, order, writ, injunction, decree, statute, rule or regulation applicable to Oneida or any of its Subsidiaries or their respective assets; except, in case of clauses (ii) and (iii) above, for any such breach, default, right, lien, charge, encumbrances, violation or conflict which, individually or in the aggregate, would not have a Material Adverse Effect on Oneida.

(d) Except as Previously Disclosed, other than as contemplated by Section 5.3 hereof, no consent, approval or authorization of, or declaration, notice, filing or registration with, any governmental or regulatory authority, or any other Person, is required to be made or obtained by Oneida on or prior to the Closing Date in connection with the execution, delivery and performance of this Agreement or any of the Transaction Documents to which it is a party or the consummation of the Transactions.

3.5. Regulatory Filings. Each of Oneida and its Subsidiaries has filed all reports required by statute or regulation to be filed with any federal or state bank regulatory agency, except where the failure to so file would not have a Material Adverse Effect on Oneida, and such reports were prepared in accordance with the applicable statutes, regulations and instructions in existence as of the date of filing of such reports in all material respects.

3.6. SEC Documents; Financial Statements; Books and Records; Minute Books. Oneida has filed or furnished all forms, reports and documents required to be filed with or furnished to the SEC since January 1, 2012. The SEC Documents filed or furnished by Oneida (i) were prepared in all material respects in accordance with the requirements of the Securities Act or the Exchange Act, as the case may be, and (ii) did not at the time they were filed (or if amended or superseded by a filing prior to the date of this Agreement, then on the date of such

filing) contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The Oneida Financial Statements filed by Oneida in its SEC Documents prior to the date of this Agreement, and the Oneida Financial Statements filed by Oneida in its SEC Documents after the date of this Agreement will fairly present, the consolidated financial position of Oneida as of the dates indicated and the consolidated income, changes in shareholders’ equity and cash flows of Oneida and its consolidated Subsidiaries for the periods then ended and each such financial statement has been or will be, as the case may be, prepared in conformity with GAAP applied to financial institutions applied on a consistent basis, except that the unaudited interim financial statements were or are subject to normal and recurring year-end adjustments which were not or are not expected to be material in amount, and may not contain certain notes as may be permitted by the applicable rules promulgated by the SEC. The books and records of Oneida and each of its Subsidiaries fairly reflect in all material respects the transactions to which it is a party or by which its properties are subject or bound. Such books and records have been properly kept and maintained and are in compliance with all applicable legal and accounting requirements in all material respects. The minute books of Oneida and each of its Subsidiaries contain records which are accurate in all material respects of all corporate actions of its shareholders and Board of Directors (including committees of its Board of Directors).

3.7. Material Adverse Change. Oneida has not, on a consolidated basis, suffered any change in its financial condition, results of operations or business since December 31, 2013, which, individually or in the aggregate with any other such changes, would constitute a Material Adverse Effect with respect to Oneida.

3.8. Absence of Undisclosed Liabilities. Neither Oneida nor any of its Subsidiaries has any liability (contingent or otherwise) that is material to Oneida on a consolidated basis, or that, when combined with all similar liabilities, would be material to Oneida on a consolidated basis, except as disclosed in the Oneida Financial Statements contained in an SEC Document filed prior to the date hereof and except for liabilities incurred in the ordinary course of business consistent with past practice since September 30, 2014.

(j) made or permitted any amendment or termination of any material contract, agreement or license to which it is a party, other than in the ordinary course of business consistent with past practice;

(o) entered into any real estate or equipment lease, requiring aggregate rental payments in excess of $25,000; or

(p) agreed to or otherwise become obligated to do any of the foregoing.

3.10. Properties.

All OREO is carried on the books of Oneida, net of reserves, at fair market value less cost to sell.

(c) All reserves or other allowances for Loan losses reflected in the Oneida Financial Statements comply with all applicable laws and are adequate under GAAP. Neither Oneida nor any of its Subsidiaries has been notified by any state or federal bank regulatory agency that its reserves are inadequate or that the practices and policies of Oneida and its Subsidiaries in establishing its reserves reflected in the Oneida Financial Statements, and in accounting for delinquent and classified assets generally fail to comply with applicable accounting or regulatory requirements, or that bank regulators or Oneida’s independent auditor believes such reserves to be inadequate or inconsistent with the historical loss experience of Oneida and its Subsidiaries. Oneida’s reserves and allowances for Loan losses are in compliance

with the standards established by state and federal bank regulatory agencies, are sufficient at the date of this Agreement to cover its reasonably anticipated Loan losses, and are consistent with Oneida’s past practices.

(d) All Loans owned by Oneida or any Oneida Subsidiary, or in which Oneida or any Oneida Subsidiary has an interest, comply in all material respects with all applicable laws, including, but not limited to, applicable usury statutes, underwriting and recordkeeping requirements and the Truth in Lending Act, the Equal Credit Opportunity Act, and the Real Estate Settlement Procedures Act.

(e) Each mortgage held by Oneida and each Oneida Subsidiary creates a valid and enforceable lien on the real property described therein having the priority indicated by the terms of such mortgage, subject only to such exceptions as are described in attorneys’ opinions regarding title or in title insurance policies in the mortgage files relating to the Loans secured thereby or are not material as to the collectability of such Loans. Oneida and each Oneida Subsidiary have properly perfected or caused to be properly perfected all security interests, liens and other interests in collateral securing any Loans made by it. Oneida and each Oneida Subsidiary has full recourse to the borrowers and guarantors of all Loans held by them, and neither Oneida nor any Oneida Subsidiary has taken action which would result in a waiver or negation of any rights or remedies available against the borrower or guarantor on any Loan.

(f) Each outstanding Loan participation sold by Oneida or any Oneida Subsidiary was sold with the risk of non-payment of all or any portion of that underlying loan to be shared by each participant proportionately to the share of such Loan represented by such participation without any recourse of such other lender or participant to Oneida or any Oneida Subsidiary for payment or repurchase of the amount of such Loan represented by the participation or liability under any yield maintenance or similar obligation.

(g) Oneida has Previously Disclosed to CBSI in writing: (i) all Loans held by Oneida or any Oneida Subsidiary that, during the past twelve months, have had their respective terms to maturity accelerated or with respect to which Oneida or an Oneida Subsidiary has notified the borrower of its intention to accelerate the Loan or declare a default, (ii) all Loan commitments or lines of credit that have been terminated or amended by Oneida or an Oneida Subsidiary during the past 12 months by reason of a default or adverse developments in the condition of the borrower or other events or circumstances affecting the credit of the borrower, (iii) each borrower, customer or other party which has notified Oneida or an Oneida Subsidiary during the past 12 months of, or has asserted against Oneida, orally or in writing, any “lender liability” or similar claim, (iv) all Loans, (A) that are contractually past due 90 days or more in the payment of principal and/or interest, (B) that are on non-accrual status, (C) that as of the date of this Agreement are classified as “Other Loans Specially Mentioned”, “Special Mention”, “Substandard”, “Doubtful”, “Loss”, “Classified”, “Criticized”, “Watch List” or words of similar import, together with the principal amount of and accrued and unpaid interest on each such loan and the identity of the obligor thereunder, (D) where, during the past two years, the interest rate terms have been reduced and/or the maturity dates have been extended subsequent to the agreement under which the Loan was originally created due to concerns regarding the borrower’s ability to pay in accordance with such initial terms, or (E) where a specific reserve allocation

exists in connection therewith and (v) all assets classified by Oneida as OREO and all other assets currently held that were acquired through foreclosure or in lieu of foreclosure.

3.12. Tax Matters.

(a) Oneida and each of its Subsidiaries have timely filed federal and state income Tax Returns for each year through December 31, 2013 and have timely filed, or caused to be filed, all other Tax Returns required to be filed with respect to Oneida or any of its Subsidiaries. All Taxes due by or on behalf of Oneida or any of its Subsidiaries have been paid or adequate reserves have been established on the Oneida Financial Statements for the payment of such Taxes.

Subject to the terms and conditions of this Agreement, no party hereto shall take or fail to take, or cause or permit its Subsidiaries to take or fail to take, or to the best of its ability permit to be taken or not to be taken by any third party, any action that would substantially impair the prospects of completing the Merger pursuant to this Agreement, that would materially delay such completion, or that would adversely affect the qualification of the Merger as a reorganization within the meaning of Section 368(a) of the Code. In the event that either party has taken any action, whether before, on or after the date hereof, that would adversely affect such qualification, each party shall take such action as the other party may reasonably request to cure such effect to the extent curable without a Material Adverse Effect on either of the parties.

(b) Each party hereto shall give prompt notice to the other party of (i) the occurrence, or failure to occur, of any event which occurrence or failure would be reasonably likely to cause any representation or warranty contained in this Agreement to be untrue or inaccurate at any time from the date hereof to the Closing Date such that the condition set forth in Section 6.2(a) or 6.3(a), as applicable, would not be met if such failure to be true or accurate were to occur or be continuing on the Closing Date, and (ii) any material failure of any party to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder, and each party shall use all reasonable best efforts in good faith to remedy such failure.

(c) From the date of this Agreement through the Effective Time, to the extent permitted by law, Oneida shall cause the Oneida Banks to provide such assistance to Community Bank as reasonably necessary for Community Bank to prepare for the conversion and transfer in connection with the Merger all information concerning the loans, deposits and other assets and liabilities of the Oneida Banks into Community Bank’s own data processing system, with a view to facilitating the integration of Community Bank’s and the Oneida Banks’ systems and otherwise combining Community Bank’s and the Oneida Banks’ operations upon consummation of the Merger. Such assistance shall include providing Community Bank with computer file instructions with respect to the information in its data processing system regarding the assets and liabilities of the Oneida Banks, together with operational procedures designed to implement the transfer of such information to Community Bank, provided that the confidentiality of customer information shall be preserved and no information shall be transferred until the Effective Time. After execution of this Agreement, the Oneida Banks and Community Bank shall each designate

an individual to serve as liaison concerning the transfer of data processing information and other similar operational matters. Prior to the Effective Time, Oneida shall not enter into, extend, modify, or terminate, any agreement with a third party vendor providing information technology or data processing services or software to Oneida or any Oneida Subsidiary without the prior written consent of CBSI, which consent shall not be unreasonably withheld or delayed.

(d) Each party shall provide, and shall request its auditors to provide, the other party with such historical financial information regarding it (and related audit reports and consents) as the other party may reasonably request for disclosure purposes under the Securities Laws.

(e) Each party shall take all steps, as may be necessary or appropriate, to cause the transactions contemplated by Article II and any other dispositions of equity securities of Oneida (including derivative securities) or acquisitions of equity securities of CBSI in connection with the consummation of the Transactions contemplated by this Agreement to be exempt under Rule 16b-3 promulgated under the Exchange Act.

5.5. Investigation and Confidentiality.

(a) Oneida and CBSI each will keep the other advised of all material developments relevant to its and its Subsidiaries’ businesses and to consummation of the Transactions. Without limiting the generality of the foregoing, (i) representatives of Oneida and CBSI shall confer periodically regarding the financial condition, assets, liabilities, operations and business of Oneida and the Oneida Banks and matters relating to the completion of the Transactions, and (ii) as soon as reasonably available, but in no event more than three (3) business days after filing, Oneida shall furnish to CBSI all reports filed by it or the Oneida Banks with, and all material notices received by it or the Oneida Banks from, any regulatory authority subsequent to the date hereof, subject to any regulatory requirements to maintain the confidentiality of such reports and notices.

(b) Oneida and CBSI each may make or cause to be made such investigation of the financial and legal condition of the other as such party reasonably deems necessary or advisable in connection with the Transactions, provided, however, that such investigation shall be reasonably related to such transactions and the party conducting such investigation shall use its reasonable best efforts to minimize any disruptions to the operations of the other party. CBSI and Oneida agree to furnish the other and the other’s advisors with such financial data and other information with respect to its business and properties as such other party shall from time to time reasonably request, including, without limitation, information with respect to Oneida’s delinquent or problem Loans of the nature described in Section 3.11.

(c) Promptly following the occurrence of an event or fact which, if such event or fact had occurred prior to the date of this Agreement, would have been required to have been Previously Disclosed, the applicable party shall update its disclosure letter required to be delivered under the terms of this Agreement unless such event or fact is disclosed in an SEC Document filed with the SEC.

(d) Oneida shall provide CBSI, no later than fifteen (15) days after the end of each month, a written update on each of its Delinquent Loans and Loans Previously Disclosed pursuant to Section 3.11(g).

(e) No update of a party’s disclosure letter after the date hereof, and no investigation done after the date hereof pursuant to this Section 5.5 or otherwise shall affect or be deemed to modify any representation or warranty made by, or the conditions to the obligations to consummate the Merger of, any party hereto.

(f) Each party hereto shall hold all information furnished by the other party or any of such party’s Subsidiaries or representatives pursuant to this Agreement in confidence and in accordance with the confidentiality agreement dated December 19, 2014, between Oneida and CBSI (the “Confidentiality Agreement”).

5.6. Press Releases and Other Public Disclosures. Oneida and CBSI shall agree with each other as to the form and substance of any press release related to this Agreement or the Transactions, and shall consult and agree with each other as to the form and substance of other public disclosures related thereto, including without limitation, any communications with securities market professionals and investors, provided, however, that nothing contained herein shall prohibit any party, following notification to the other parties, from making any disclosure which, in the opinion of its counsel, is required by applicable law or NYSE or NASDAQ rules.

5.7. Actions Pending the Merger.

(a) Prior to the Closing Date, and except as otherwise provided for by this Agreement or consented to or approved in writing by the other party hereto, each of CBSI and Oneida shall, and shall cause each of its Subsidiaries to, use its reasonable best efforts to preserve its properties, business and relationships with customers, employees and other Persons.

(b) Except with the prior written consent of CBSI (which consent will not be unreasonably withheld or delayed) or as expressly permitted by this Agreement, Oneida shall not, and shall not permit any of its Subsidiaries to:

(1) carry on its business other than in the usual, regular and ordinary course in substantially the same manner as heretofore conducted, or incur an obligation in excess of $50,000 in the aggregate or which requires performance over more than one year (other than loans and investments booked in the usual, regular and ordinary course of business);

(2) declare, set aside, make or pay any dividend or other distribution in respect of its capital stock or earnings other than its regular quarterly cash dividends on Oneida Common Stock in amounts consistent with past practice;

(3) issue any shares of its capital stock or permit any treasury shares to become outstanding (except that Oneida may issue shares of Oneida Common Stock pursuant to a valid exercise of an unexpired Oneida Option), or redeem, purchase or otherwise acquire any shares of its capital stock or any securities or obligations convertible into or exchangeable for any shares of its capital stock;

(4) incur any additional debt obligation or other obligation for borrowed money other than in the ordinary course of business consistent with past practice;

(6) amend or otherwise change its articles of incorporation or articles of association or bylaws; impose, or suffer the imposition, on any share of capital stock of Oneida of any lien, charge or encumbrance;

(7) merge or consolidate with, or acquire control over, any Person or create any Subsidiary;

(8) waive or release any material right or cancel or compromise any material debt or claim other than in the ordinary course of business consistent with past practice with prior notice to CBSI;

(9) sell, liquidate, pledge or encumber or dispose of, or acquire any, assets with a value in excess of $50,000 (other than assets acquired in foreclosure, in lieu of foreclosure or other legal proceedings relating to collateral for Loans, in each case in the ordinary course of business consistent with past practice); make any capital expenditure in excess of $50,000 in the aggregate; or establish new branches or other similar facilities, close existing branches or similar facilities or enter into or modify any leases or other contracts relating thereto;

(10) hire any new employee without first consulting with CBSI; increase the rate of compensation of, pay or agree to pay any bonus to, or provide any additional employee benefit or incentive (including without limitation, any “change of control” or severance payment) to any of its directors, officers or employees except as required by law or contractual obligation in effect as of the date hereof; or become party to, adopt, terminate, amend, or commit itself to, any pension, retirement, profit sharing or welfare benefit plan or agreement or employment agreement, other than in the ordinary course of business consistent with past practice or except as required by existing plans or agreements; or accelerate the vesting of any deferred compensation;

(13) take any action that could result in (i) any of its representations or warranties in this Agreement being or becoming untrue in any material respects at any time prior to the Effective Time, (ii) any of the conditions to the Merger set forth in Article VI not being satisfied, except as may be required by law or (iii) materially delaying the receipt of necessary regulatory approvals for the Transactions except as may be required by law or regulatory requirement; or

(14) agree to do any of the foregoing or take any other action which would in any manner interfere with, impede, delay, or make more costly the consummation of the Transactions.

(c) CBSI shall not, except with the prior written consent of Oneida (which consent shall not unreasonably be withheld or delayed) or as expressly permitted by this Agreement, carry on its business other than in the usual, regular and ordinary course in substantially the same manner as heretofore conducted; provided, however, that nothing herein shall be construed to prevent CBSI from acquiring or agreeing to acquire any Person, by merging or consolidating with, by purchasing an equity interest in or a portion of the assets of, or by any other manner, such Person or taking actions reasonably related thereto, so long as such transaction would not materially delay or prevent the consummation of the Transactions.

5.8. Certain Policies. Following receipt of all regulatory approvals required to consummate the Merger and the Bank Mergers and approval of this Agreement at the Oneida Shareholders’ Meeting:

(a) Oneida shall, consistent with GAAP and applicable law and on a basis mutually satisfactory to it and CBSI, modify and change its accounting, investment, loan, litigation and real estate valuation policies and practices (including loan classifications, content and size of investment portfolio, and levels of reserves and accruals) so as to be applied, in all material respects, on a basis that is consistent with that of CBSI;

(b) Oneida and CBSI shall review the adequacy of reserves for loan losses currently established by Oneida and, if deemed warranted by both parties under GAAP, Oneida shall make mutually acceptable changes to such reserves; and

(c) Oneida shall consult with CBSI with respect to determining the amount and timing of recognizing, for financial accounting and income Tax reporting purposes, Oneida’s expenses incurred in connection with the Transactions and, subject to GAAP and applicable law, Oneida shall recognize its costs and expenses in connection with the Transactions at such time or times as are reasonably requested by CBSI.

5.9. Employee Benefits; Directors and Management; Indemnification.

(a) The current employees of Oneida or any of its Subsidiaries who continue as employees of CBSI or its Subsidiaries after the Effective Time (“Continuing Employees”) shall be given credit for past service with Oneida for purposes of determining eligibility for and vesting of employee benefits (but not for pension benefit accrual purposes) under all welfare and retirement programs maintained by CBSI or its Subsidiaries in which such Continuing

Employees participate following the Merger and for purposes of determining length of vacation, sick time, paid time off and severance under CBSI’s applicable plan or policy. In the event that the employment of any Continuing Employee shall be terminated by CBSI or one of its Subsidiaries without cause within twelve months after the Effective Time, such Continuing Employee shall be entitled (subject to meeting applicable eligibility and vesting requirements) to receive severance benefits no less than those provided under the terms of CBSI’s severance policy in effect as of the date of this Agreement, which has been Previously Disclosed. In the event that the employment of any Continuing Employee shall be terminated by CBSI or one of its Subsidiaries without cause more than twelve months after the Effective Time, such Continuing Employee shall be entitled (subject to meeting applicable eligibility and vesting requirements) to receive severance benefits no less than those provided under the terms of CBSI’s severance policy in effect as of the date of termination of employment.

(b) Prior to the Effective Time, Oneida shall take all actions, provided such actions comply with applicable law or do not trigger adverse tax consequences to any employee or independent contractor of Oneida or any Oneida Subsidiary, that may be requested by CBSI in writing upon advance notice of not less than 30 days with respect to (i) causing one or more Oneida Plans to terminate as of or immediately prior to the Effective Time or for benefit accrual and entitlements to cease as of the Effective Time, (ii) causing the continuation on and after the Effective Time of any contract, arrangement or insurance policy relating to any Oneida Plan for such period as may be requested by CBSI, or (iii) cooperating with CBSI to facilitate the merger of any Oneida Plan into any CBSI Plan as of or following the Effective Time.

(c) CBSI shall honor the employment agreements and severance arrangements in effect as of the date of this Agreement and Previously Disclosed by Oneida to CBSI, except to the extent that any such agreements or arrangements are superseded or terminated as of or following the Effective Time, with the written consent of the affected parties.

(d) In the event of any termination of any Oneida or any Oneida Subsidiary health plan or consolidation of any such plan with any CBSI or CBSI Subsidiary health plan, CBSI shall make available to Continuing Employees and their dependents employer-provided health coverage on the same basis as it provides such coverage to CBSI or CBSI Subsidiary employees. Unless a Continuing Employee causes coverage to terminate under an Oneida or Oneida Subsidiary health plan prior to the time that a Continuing Employee becomes eligible to participate in the CBSI or CBSI Subsidiary health plan, neither CBSI nor any CBSI Subsidiary shall terminate the existing coverage of any of the Continuing Employees or their dependents under any of the Oneida or Oneida Subsidiary health plans prior to the time such Continuing Employees and their dependents become eligible to participate in the health plans, programs and benefits common to all employees of CBSI or CBSI Subsidiary and their dependents. In the event of a termination or consolidation of any Oneida or Oneida Subsidiary health plan on or after the Effective Time, former employees of Oneida or Oneida Subsidiary and qualified beneficiaries will have the right to continued coverage under group health plans of CBSI to the extent required by COBRA.

(e) At the Effective Time, CBSI shall, or direct Oneida to, pay each participant in the Oneida Cash Incentive Plans a lump sum cash payment equal to the pro-rata portion of his or her annual incentive award payable under the Oneida Cash Incentive Plans,

calculated from the first day of the plan year beginning on January 1, 2015 (or beginning on January 1, 2016 if the Effective Time occurs in the 2016 calendar year) until the Effective Time, as if the company and individual performance goals are achieved at “target” performance for such award.

(f) Prior to the Effective Time, CBSI shall cause its Board of Directors and Community Bank’s Board of Directors (subject to their continuing fiduciary duties between the date hereof and the Effective Time) to take all requisite actions to expand the size thereof by two directors and appoint Eric E. Stickels and Michael R. Kallet(each, a “New Director”) as directors of CBSI and Community Bank to fill the vacancies created by the expansion, effective as of the Effective Time. Subject to the exercise of the fiduciary duties of CBSI’s Board of Directors, CBSI shall cause the Nominating and Corporate Governance Committee to nominate, and shall cause its Board to recommend for election, each New Director at CBSI’s next annual meeting of shareholders at which they are standing for election. Nothing contained in this Section 5.9(f) shall be construed to limit the ability of the respective Boards of Directors of CBSI and Community Bank to further increase the size of such Boards from time to time as they may deem appropriate.

(g) (1) In the event of any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal or administrative, including, without limitation, any such claim, action, suit, proceeding or investigation in which any Person (the “Indemnified Party”) who is now, or has been at any time prior to the date of this Agreement, or who becomes prior to the Effective Time, a director or officer of Oneida is, or is threatened to be, made a party based in whole or in part on, or arising in whole or in part out of, or pertaining to (i) the fact that he is or was a director, officer or employee of Oneida or any of its Subsidiaries, or (ii) this Agreement or any of the Transactions, whether in any case asserted or arising before or after the Effective Time, CBSI shall, for a period of six years after the Effective Time, indemnify and hold harmless, to the fullest extent permitted by law, each such Indemnified Party against any losses, claims, damages, liabilities, costs, expenses (including reasonable attorney’s fees and expenses in advance of the final disposition of any claim, suit, proceeding or investigation to each Indemnified Party to the fullest extent permitted by the DGCL upon receipt of any undertaking required by the DGCL), judgments, fines and amounts paid in settlement in connection with any such threatened or actual claim, action, suit, proceeding or investigation, and in the event of any such threatened or actual claim, action, suit, proceeding or investigation (whether asserted or arising before or after the Effective Time), the Indemnified Party may retain counsel reasonably satisfactory to them after consultation with CBSI; provided, however, that (1) CBSI shall have the right to assume the defense thereof and upon such assumption CBSI shall not be liable to any Indemnified Party for any legal expenses of other counsel or any other expenses subsequently incurred by any Indemnified Party in connection with the defense thereof, except that if CBSI elects not to assume such defense or counsel for the Indemnified Party reasonably advises the Indemnified Party that there are issues which raise conflicts of interest between CBSI and the Indemnified Party, the Indemnified Party may retain counsel reasonably satisfactory to them after notification, and CBSI shall pay the reasonable fees and expenses of such counsel for the Indemnified Party, (2) CBSI shall be obligated pursuant to this paragraph to pay for only one firm of counsel for all Indemnified Parties, (3) CBSI shall not be liable for any settlement effected without its prior written consent,

(4) CBSI shall have no obligation hereunder to any Indemnified Party when and if a court of competent jurisdiction shall ultimately determine, and such determination shall have become final and nonappealable, that indemnification of such Indemnified Party in the manner contemplated hereby is prohibited by applicable law, and (5) CBSI shall no obligation hereunder to defend or indemnify an Indemnified Party from a claim, action or suit between such Indemnified Party and CBSI or any of its Subsidiaries. Any Indemnified Party wishing to claim indemnification under this Section 5.9(g), upon becoming aware of any such claim, action, suit, proceeding or investigation, shall promptly notify CBSI thereof, provided that the failure of any Indemnified Party to so notify CBSI shall relieve it of its obligations to indemnify hereunder to the extent that such failure materially prejudices CBSI.

(2) The indemnification rights provided in subparagraph (1) above, are in addition to the obligations of indemnification (including the advancement of expenses) in favor of the directors and officers of Oneida (including former directors and officers) under Oneida’s articles of incorporation and bylaws (and provisions of Maryland law referenced or incorporated therein) that are assumed by CBSI by reason of the Merger.

(3) CBSI will use its reasonably best efforts to cause the Persons who served as directors or officers of Oneida on or before the Effective Time to be covered by Oneida’s existing directors’ and officers’ liability insurance policy (provided that CBSI may substitute therefor policies of at least the same coverage and amounts containing terms and conditions which are not less advantageous than such policy) but in no event shall any insured Person be entitled under this Section 5.9 to insurance coverage more favorable than that provided to him or her in such capacities as of the date hereof with respect to acts or omissions resulting from their service as such on or prior to the Effective Time. Such insurance coverage shall commence at the Effective Time and will be provided for a period of no less than six years after the Effective Time; provided, however, that in no event shall CBSI be required to expend more than 150% of the current amount expended by Oneida to maintain or procure insurance coverage pursuant hereto. Prior to the Effective Time, Oneida agrees to renew any such existing insurance or to purchase any “discovery period” insurance provided for thereunder at CBSI’s request.

5.10. Dividends; Termination of DRIP Plan. After the date of this Agreement, CBSI and Oneida shall coordinate with the other the declaration of any dividends in respect of CBSI Common Stock and Oneida Common Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of Oneida Common Stock shall not receive dividends other than regular dividends thereon, subject to any regulatory limitations, or fail to receive such regular dividends subject to any regulatory limitations, for any calendar quarter prior to the Effective Time with respect to their shares of Oneida Common Stock and for any calendar quarter following the Effective Time with respect to any shares of CBSI Common Stock that such holder receives as Merger Consideration. Oneida shall suspend its DRIP Plan effective as of the date of this Agreement with the effect that no additional shares of Oneida Common Stock shall be issued thereunder prior to the Effective Time or the termination of this Agreement. Prompt notice of such suspension shall be given to all Oneida shareholders. Upon the Effective Time, the DRIP Plan shall be terminated, and Oneida and CBSI shall cooperate in providing any required notice of such termination of such termination to the shareholders of Oneida.

5.11. Takeover Laws. No party hereto shall take any action that would cause the Transactions to be subject to the requirements imposed by any Takeover Law, and each of them shall take all necessary steps within its control to exempt (or ensure the continued exemption of) all such Transactions from, or if necessary challenge the validity or applicability of, any applicable Takeover Law, as now or hereafter in effect.

5.12. No Solicitation.

(a) Subject to Section 5.12(b) hereof, from and after the date of this Agreement until the earlier of the Closing or the termination of this Agreement in accordance with its terms, neither Oneida nor any Person acting on behalf of Oneida shall, directly or indirectly, (a) solicit, initiate or respond to discussions or engage in negotiations with any Person (whether such negotiations are initiated by Oneida or otherwise) or take any other action intended or designed to facilitate the efforts of any Person, other than CBSI, relating to the possible acquisition, recapitalization or other business combination involving Oneida or any of its Subsidiaries (whether by way of merger, purchase of capital stock, purchase of assets or otherwise) or twenty-five percent (25%) or more of its capital stock or assets (with any such efforts by any such Person, including a firm proposal to make such an acquisition, to be referred to as “Takeover Proposal”), (b) provide non-public information with respect to Oneida or any of its Subsidiaries to any Person, other than CBSI and its professional advisors or Oneida’s professional advisors, or (c) enter into an agreement, or a letter of intent or term sheet, with any Person, other than CBSI, providing for a possible Takeover Proposal. If Oneida receives any offer or proposal relating to a Takeover Proposal, Oneida shall immediately notify CBSI thereof, including information as to the identity of the party making any such offer or proposal and the specific terms of such offer or proposal, as the case may be. Oneida shall immediately cease and cause to be terminated any activities, discussions, or negotiations conducted before the date of this Agreement with any Person other than CBSI with respect to any Takeover Proposal. Oneida will promptly (and in any event within twenty-four (24) hours) advise CBSI following receipt of any communication or inquiry which could reasonably be expected to lead to a Takeover Proposal and the substance thereof (including any terms and conditions discussed and the identity of the party making such communication or inquiry) and will promptly advise CBSI of any related developments, discussions and negotiations on a current basis.

(b) (i) Notwithstanding anything to the contrary contained in Section 5.12(a) prior to the Closing or the termination of this Agreement in accordance with its terms, to the extent the Board of Directors of Oneida determines, in good faith, after consultation with outside legal counsel, that a failure to take such actions would constitute a violation of its fiduciary duties under applicable law, Oneida may: participate in discussions or negotiations with, and, subject to the requirements of Section 5.12(c), furnish non-public information, and afford access to the properties, books or records of Oneida or any of its Subsidiaries, to any Person after such Person has delivered to Oneida in writing an unsolicited bona fide Takeover Proposal with respect to Oneida or any of its Subsidiaries (which has not been withdrawn) which the Board of Directors of Oneida in its good faith judgment determines, after reasonable inquiry and consultation with its financial advisor (i) would be reasonably likely to result in a transaction more favorable than that contemplated by this Agreement to the shareholders of Oneida (which judgment must be reasonable), and (ii) that the Person making such Takeover Proposal is

financially capable of consummating such Takeover Proposal or that the financing necessary to consummate such Takeover Proposal, to the extent required, is then committed or is capable of being obtained by such Person (a “Superior Proposal”). In addition, notwithstanding the provisions of Section 5.12(a) above, in connection with a submitted, written bona fide Takeover Proposal or potential Takeover Proposal, Oneida shall refer any third party to this Section 5.12 or make a copy of this Section 5.12 available to such third party.

(ii) In the event Oneida or any of its Subsidiaries receives a Superior Proposal, prior to taking any action with respect thereto Oneida shall (A) provide CBSI not less than seventy-two (72) hours prior written notice of its intent to take such action and any meeting of the Board of Directors of Oneida at which such Board of Directors is reasonably expected to consider a Superior Proposal, (B) not recommend to its shareholders a Superior Proposal for a period of not less than three (3) business days after CBSI’s receipt of a copy of such Superior Proposal and the identity of the third party, and (C) not enter into a definitive agreement relating to such Superior Proposal unless CBSI fails to match the terms of the Superior Proposal, or provide an alternative proposal upon terms which, after consideration by the Board of Directors of Oneida in good faith, are not more favorable than the Superior Proposal, within three (3) business days after CBSI’s receipt of a copy of such Superior Proposal and the identity of the third party; and provided, further, that unless this Agreement is terminated pursuant to Article VII, nothing contained in this Section 5.12(b) shall limit Oneida’s obligation to hold and convene the Oneida Shareholders’ Meeting in accordance with Section 5.1 hereof (regardless of whether the recommendation of the Board of Directors of Oneida shall have been withdrawn, modified or not yet made) or to provide the shareholders of Oneida with material information relating to this Agreement and the Oneida Shareholders’ Meeting. Any material amendment to any Superior Proposal shall be deemed to be a new Superior Proposal for purposes of determining any time periods and obligations of Oneida pursuant to this Section 5.12(b)(ii).

(c) Notwithstanding anything to the contrary herein, neither Oneida nor any of its Subsidiaries shall provide any non-public information to a third party unless: (x) Oneida provides such non-public information pursuant to a nondisclosure agreement with terms regarding the protection of oral or written confidential information at least as restrictive as such terms in the Confidentiality Agreement heretofore entered into by the parties hereto; and (y) such non-public information has been previously delivered or made available to CBSI.

(a) The representations and warranties of Oneida set forth in Article III hereof shall be true and correct as of the date of this Agreement and as of the Closing Date as though made on and as of the Closing Date (or, in the case of any representation and warranty which specifically relates to an earlier date, as of such earlier date), except as otherwise contemplated by this Agreement or consented to in writing by CBSI; provided, however, that (i) in determining whether or not the condition contained in this paragraph (a) is satisfied, no effect shall be given to any qualifications or exceptions in such representations and warranties relating to materiality or Material Adverse Effect and (ii) the condition contained in this paragraph (a) shall be deemed to be satisfied unless the failure of such representations and warranties to be so true and correct constitute, individually or in the aggregate, a Material Adverse Effect on Oneida;

(b) Oneida shall have in all material respects performed all obligations and complied with all covenants required by this Agreement to be performed or complied with at or prior to the Closing Date;

(c) Oneida shall have delivered to CBSI a certificate, dated the Closing Date and signed by its Chief Executive Officer, to the effect that the conditions set forth in paragraphs (a) and (b) of this Section 6.3 have been satisfied;

(d) The required regulatory approvals approving the Transactions shall contain no condition or requirement which would be reasonably likely to result in a Material Adverse Effect on CBSI following the consummation of the Transactions;

(e) To the extent that any material, lease, license, loan, financing agreement or other contract or agreement to which Oneida is a party requires the consent of or waiver from the other party thereto as a result of the Transactions, such consent or waiver shall have been obtained, unless the failure to do so would not have a Material Adverse Effect on CBSI; and

(f) Oneida shall have delivered to CBSI duly-executed copies of each of the Transaction Documents together with such other documents, consents or other deliverables as may be reasonably requested by CBSI to consummate the Transactions.

ARTICLE VII

TERMINATION

7.1. Termination. This Agreement may be terminated at any time prior to the Effective Time, either before or after approval by the shareholders of Oneida:

(a) by the mutual written consent duly authorized by the respective Boards of Directors of the parties hereto;

(b) by CBSI in writing, if Oneida has, or by Oneida in writing, if CBSI has, breached (i) any covenant or agreement contained herein or (ii) any representation or warranty contained herein, and in either case if (x) to the extent that such breach is curable, such breach has not been cured within 30 days after the date on which written notice thereof is given to the breaching party and (y) such breach would entitle the non-breaching party not to consummate the Transactions under Article VI hereof;

(c) by any party hereto in writing, if the applications for governmental approval referred to in Section 5.3 hereof have been denied, or if any governmental entity of competent jurisdiction shall have issued a final nonappealable order enjoining or otherwise prohibiting the Merger;

(d) by any party hereto in writing, if the shareholders of Oneida do not approve this Agreement and the Transactions at the special meeting duly called for that purpose;

(e) by any party hereto in writing, if the Merger shall not have been consummated by the close of business on December 31, 2015, unless the failure to so consummate by such date shall be principally due to the failure of the party seeking to terminate this Agreement to perform or observe the covenants and agreements set forth herein;

(f) by CBSI, if (i) the Board of Directors of Oneida shall withdraw, modify or change its approval or recommendation of this Agreement or the Transactions in a manner adverse to CBSI, or Oneida shall have failed to include in the Proxy Statement/Prospectus the recommendation of its Board of Directors in favor of the approval of this Agreement or the Transactions; (ii) following its receipt of a Takeover Proposal or the public announcement of a Takeover Proposal, Oneida shall fail to timely comply with the covenants contained in Section 5.2; (iii) the Board of Directors of Oneida shall have recommended to the shareholders of Oneida a Superior Proposal, or Oneida shall have executed a letter of intent, a definitive agreement or similar document with respect to a Superior Proposal; (iv) a tender offer or exchange offer for 25% or more of the outstanding shares of Oneida Common Stock is commenced and Oneida shall not have sent to its shareholders, within 10 business days after the commencement of such tender or exchange offer, a statement that the Board of Directors of Oneida recommends rejection of such tender or exchange offer; or (v) a Takeover Proposal (other than a tender or exchange offer covered by clause (iv) of this Section 7.1(f)) with respect to Oneida is publicly announced and, upon CBSI’s request, Oneida fails to issue a press release announcing its opposition to such Takeover Proposal within three (3) business days after such request;;

(g) by Oneida, if the Board of Directors of Oneida shall have recommended to the shareholders of Oneida a Superior Proposal, or Oneida shall have executed a letter of intent, a definitive agreement or similar document with respect to a Superior Proposal, in each case in accordance with Section 5.12, provided that Oneida has complied with all provisions thereof.

(h) by Oneida, if the Board of Directors of Oneida so determines by a vote of the majority of the members of the entire Board of Directors of Oneida, at any time during the five-day period commencing with the Determination Date (as defined below), if both of the following conditions are satisfied:

(A) The number obtained by dividing the Average Closing Price by the Starting Price (as defined below) (the “CBSI Ratio”) shall be less than 0.80; and

(B) (x) the CBSI Ratio shall be less than (y) the number obtained by dividing the Final Index Price by the Index Price on the Starting Date (each as defined below) and subtracting 0.20 from the quotient in this clause (B) (y) (such number in this clause (B) (y) that results from dividing the Final Index Price by the Index Price on the Starting Date being referred to herein as the “Index Ratio”);

subject, however, to the following three sentences. If Oneida elects to exercise its termination right pursuant to this Section 7.1(h), it shall give written notice to CBSI (provided that such notice of election to terminate may be withdrawn at any time within the aforementioned five-day period). During the five-day period commencing with its receipt of such notice, CBSI shall have the option to increase the consideration to be received by the holders of Oneida Common Stock hereunder, by adjusting the Exchange Ratio (calculated to the nearest one one-thousandth) to equal the lesser of a number (rounded to the nearest one one-thousandth) obtained by dividing (A) the product of the Starting Price, 0.80 and the Exchange Ratio (as then in effect) by (B) the Average Closing Price and (y) a number (rounded to the nearest one one-thousandth) obtained by dividing (A) the product of the Index Ratio and the Exchange Ratio (as then in effect) by (B) the CBSI Ratio. If CBSI so elects within such five-day period, it shall give prompt written notice to Oneida of such election and the revised Exchange Ratio, whereupon no termination shall have occurred pursuant to this Section 7.1(h) and this Agreement shall remain in effect in accordance with its terms (except as the Exchange Ratio shall have been so modified).

For purposes of this Section 7.1(h) the following terms shall have the meanings indicated:

“Average Closing Price” shall mean the average of the daily closing prices for the shares of CBSI Common Stock for the 20 consecutive full trading days on which such shares are actually traded on the NYSE (as reported by The Wall Street Journal or, if not reported thereby, any other authoritative source) ending at the close of trading on the Determination Date.

“Determination Date” shall mean the first business day after the date all regulatory approvals (or waivers thereof) required to consummate the Merger and the Bank Mergers have

been obtained (disregarding any waiting period).

“Final Index Price” shall mean the average of the Index Prices for the 20 consecutive full trading days ending on the trading day prior to the Determination Date.

“Index Price” shall mean the closing price on the Starting Date of the SNL Midcap U.S. Bank Index.

“Starting Date” shall mean the last trading day immediately preceding the date of the first public announcement of entry into this Agreement.

“Starting Price” shall mean $35.49 per share of CBSI Common Stock.

7.2. Effect of Termination. In the event this Agreement is terminated pursuant to Section 7.1 hereof, this Agreement shall become void and have no effect, except that (i) the provisions of Sections 5.5, 7.3, 8.6, 8.9 and 8.10 hereof shall survive any such termination and (ii) a termination pursuant to Section 7.1 shall not relieve the breaching party from liability for any willful breach of such covenant or agreement or representation or warranty giving rise to such termination.

7.3. Fee.

(a) Except as set forth in this Section 7.3, all fees and expenses incurred in connection with this Agreement and the Transactions (including fees and expenses of its own financial consultants, accountants and counsel) shall be paid by the party incurring such expenses, whether or not such transactions are consummated, except that CBSI and Oneida each shall bear and pay 50% of all printing and mailing costs and filing fees associated with the Registration Statement and the Proxy Statement/Prospectus and any amendment or supplement thereto.

(b) As a condition of CBSI’s willingness, and in order to induce CBSI, to enter into this Agreement and consummate the transactions contemplated by this Agreement, Oneida hereby agrees to pay CBSI, and CBSI shall be entitled to payment of FOUR MILLION NINE HUNDRED AND THIRTY THOUSAND DOLLARS ($4,930,000) (the “Fee”), as liquidated damages and not as a penalty. The Fee shall be paid within three (3) business days after written demand for payment is made by CBSI, following the occurrence of any of the events set forth below:

(i) The termination of this Agreement by Oneida pursuant to Section 7.1(g) or by CBSI pursuant to Section 7.1(f);

(ii) The entering into a definitive agreement by Oneida relating to a Takeover Proposal or the consummation of a Takeover Proposal involving Oneida within nine (9) months after the occurrence of any of the following: (i) the termination of the Agreement by CBSI pursuant to Section 7.1(b) because of a breach by Oneida; or (ii) the failure of Oneida to hold the Oneida Shareholders’ Meeting or the failure of the shareholders of Oneida to approve this Agreement, in each case after the public disclosure of a Takeover Proposal.

(c) The right to receive payment of the Fee under Section 7.3(b) will constitute the sole and exclusive remedy of CBSI and Community Bank against Oneida and its Subsidiaries and their respective officers and directors with respect to a termination listed under Section 7.3(b).

ARTICLE VIII

MISCELLANEOUS

8.1. Survival of Representations, Warranties and Covenants. All representations, warranties and covenants in this Agreement or in any instrument delivered pursuant hereto shall expire on, and be terminated and extinguished at, the Effective Time other than covenants that by their terms are to survive or be performed after the Effective Time; provided, that no such representations, warranties or covenants shall be deemed to be terminated or extinguished so as to deprive CBSI or Oneida (or any director, officer or controlling Person thereof) of any defense in law or equity which otherwise would be available against the claims of any Person, including, without limitation, any shareholder or former shareholder of either CBSI or Oneida, the aforesaid representations, warranties and covenants being material inducements to the consummation by CBSI and Oneida of the Transactions.

8.2. Amendment or Supplement. This Agreement may be amended or supplemented at any time prior to the Effective Time only by mutual agreement of the parties hereto or thereto.

No failure or delay on the part of any party hereto in the exercise of any right hereunder shall impair such right or be construed as a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor shall any single or partial exercise of any such right preclude other or further exercise thereof or of any other right.
