Berkshire Hills Bancorp shall be the surviving corporation (hereinafter sometimes referred to in such capacity as the “Surviving Corporation”) in the Merger and shall continue to be governed by the DGCL and its name and separate corporate existence, with all of its rights, privileges, immunities, powers and franchises, shall continue unaffected by the Merger.

2.2 Closing. The closing of the Merger (the “Closing”) will take place in the offices of ▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇, P.C., ▇▇▇▇ ▇▇▇▇▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇, ▇▇▇▇▇▇▇▇▇▇, D.C., or at such other location as is agreed to by the parties hereto, at 10:00 a.m. on the date designated by Berkshire Hills Bancorp within thirty days following satisfaction or waiver of the conditions to Closing set forth in Article VI (other than those conditions that by their nature are to be satisfied at the Closing), or such later date as the parties may otherwise agree (the “Closing Date”).

2.3 Effective Time. In connection with the Closing, Berkshire Hills Bancorp shall duly execute and deliver articles of merger (the “Articles of Merger”) to the Delaware Secretary of State for filing pursuant to the DGCL and to the Massachusetts Secretary of State for filing pursuant to the MBCA. The Merger shall become effective at such time as the Articles of Merger are duly filed with the Delaware Secretary of State and the Massachusetts Secretary of State or at such later date or time as Berkshire Hills Bancorp and CNB Financial agree and specify in the Articles of Merger (the date and time the Merger becomes effective being the “Effective Time”).

2.4 Effects of the Merger. The Merger will have the effects set forth in the MBCA and the DGCL. Without limiting the generality of the foregoing, and subject thereto, from and after the Effective Time, Berkshire Hills Bancorp shall possess all of the properties, rights, privileges, powers and franchises of CNB Financial and be subject to all of the debts, liabilities and obligations of CNB Financial.

2.5 Effect on Outstanding Shares of CNB Financial Common Stock.

(a) Subject to the provisions of this Agreement, hereof, by virtue of the Merger, automatically and without any action on the part of the holder thereof, each share of CNB Financial Common Stock issued and outstanding at the Effective Time, other than Excluded Shares, shall become and be converted into, as provided in and subject to the limitations set forth in this Agreement, the right to receive 0.3696 shares (the “Exchange Ratio”) of Berkshire Hills Bancorp Common Stock (the “Merger Consideration”).

(b) Notwithstanding any other provision of this Agreement, no fraction of a share of Berkshire Hills Bancorp Common Stock and no certificates or scrip therefor will be issued in the Merger; instead, Berkshire Hills Bancorp shall pay to each holder of CNB Financial Common Stock who would otherwise be entitled to a fraction of a share of Berkshire Hills Bancorp Common Stock an amount in cash, rounded to the nearest cent, determined by multiplying such fraction by the Berkshire Hills Bancorp Price.

(c) If, between the date of this Agreement and the Effective Time, the outstanding shares of Berkshire Hills Bancorp Common Stock shall have been changed into a different number of shares or into a different class by reason of any stock dividend, subdivision, reclassification, split, combination or exchange of shares, the Exchange Ratio shall be adjusted appropriately to provide the holders of CNB Financial Common Stock the same economic effect as contemplated by this Agreement prior to such event.

(d) As of the Effective Time, each Excluded Share, other than Dissenters’ Shares, shall be canceled and retired and shall cease to exist, and no exchange or payment shall be made with respect thereto. All shares of Berkshire Hills Bancorp Common Stock that are held by CNB Financial, if any, other than shares held in a fiduciary capacity or in satisfaction of a debt previously contracted, shall be canceled and shall constitute authorized but unissued shares. In addition, no Dissenters’ Shares shall be converted into shares of Berkshire Hills Bancorp Common Stock pursuant to this Section 2.5 but instead shall be treated in accordance with the provisions set forth in Section 2.11 of this Agreement.

2.6 Exchange Procedures.

(a) Appropriate transmittal materials (“Letter of Transmittal”) in a form satisfactory to Berkshire Hills Bancorp and CNB Financial shall be mailed as soon as practicable after the Effective Time to each holder of record of CNB Financial Common Stock as of the Effective Time. A Letter of Transmittal will be deemed properly completed only if accompanied by certificates representing all shares of CNB Financial Common Stock (“Certificate(s)”) to be converted thereby.

(b) At and after the Effective Time, each Certificate (except as specifically set forth in Section 2.5) shall represent only the right to receive the Merger Consideration.

(c) Prior to the Effective Time, Berkshire Hills Bancorp shall (i) reserve for issuance with its transfer agent and registrar a sufficient number of shares of Berkshire Hills Bancorp Common Stock to provide for payment of the aggregate Merger Consideration and (ii)

deposit, or cause to be deposited, with Registrar and Transfer Company (the “Exchange Agent”), for the benefit of the holders of shares of CNB Financial Common Stock, for exchange in accordance with this Section 2.6, an amount of cash sufficient to pay any cash in lieu of fractional shares pursuant to Section 2.5(b).

(d) The Letter of Transmittal shall (i) specify that delivery shall be effected, and risk of loss and title to the Certificates shall pass, only upon delivery of the Certificates to the Exchange Agent, (ii) be in a form and contain any other provisions as Berkshire Hills Bancorp may reasonably determine and (iii) include instructions for use in effecting the surrender of the Certificates in exchange for the Merger Consideration. Upon the proper surrender of the Certificates to the Exchange Agent, together with a properly completed and duly executed Letter of Transmittal, the holder of such Certificates shall be entitled to receive in exchange therefor a certificate representing that number of whole shares of Berkshire Hills Bancorp Common Stock that such holder has the right to receive pursuant to Section 2.5, and a check in the amount equal to the cash in lieu of fractional shares, if any, that such holder has the right to receive pursuant to Section 2.5, and any dividends or other distributions to which such holder is entitled pursuant to Section 2.5. Certificates so surrendered shall forthwith be canceled. As soon as practicable following receipt of the properly completed Letter of Transmittal and any necessary accompanying documentation, the Exchange Agent shall distribute Berkshire Hills Bancorp Common Stock and cash as provided herein. The Exchange Agent shall not be entitled to vote or exercise any rights of ownership with respect to the shares of Berkshire Hills Bancorp Common Stock held by it from time to time hereunder, except that it shall receive and hold all dividends or other distributions paid or distributed with respect to such shares for the account of the persons entitled thereto. If there is a transfer of ownership of any shares of CNB Financial Common Stock not registered in the transfer records of CNB Financial, the Merger Consideration shall be issued to the transferee thereof if the Certificates representing such CNB Financial Common Stock are presented to the Exchange Agent, accompanied by all documents required, in the reasonable judgment of Berkshire Hills Bancorp and the Exchange Agent, to evidence and effect such transfer and to evidence that any applicable stock transfer taxes have been paid.

(e) No dividends or other distributions declared or made after the Effective Time with respect to Berkshire Hills Bancorp Common Stock issued pursuant to this Agreement shall be remitted to any person entitled to receive shares of Berkshire Hills Bancorp Common Stock hereunder until such person surrenders his or her Certificates in accordance with this Section 2.6. Upon the surrender of such person’s Certificates, such person shall be entitled to receive any dividends or other distributions, without interest thereon, which subsequent to the Effective Time had become payable but not paid with respect to shares of Berkshire Hills Bancorp Common Stock represented by such person’s Certificates.

(f) The stock transfer books of CNB Financial shall be closed immediately upon the Effective Time and from and after the Effective Time there shall be no transfers on the stock transfer records of CNB Financial of any shares of CNB Financial Common Stock. If, after the Effective Time, Certificates are presented to Berkshire Hills Bancorp, they shall be canceled and exchanged for the Merger Consideration deliverable in respect thereof pursuant to this Agreement in accordance with the procedures set forth in this Section 2.6.

(g) Any portion of the aggregate amount of cash to be paid pursuant to Section 2.5, any dividends or other distributions to be paid pursuant to this Section 2.6 or any proceeds from any investments thereof that remains unclaimed by the shareholders of CNB Financial for six months after the Effective Time shall be repaid by the Exchange Agent to Berkshire Hills Bancorp upon the written request of Berkshire Hills Bancorp. After such request is made, any shareholders of CNB Financial who have not theretofore complied with this Section 2.6 shall look only to Berkshire Hills Bancorp for the Merger Consideration and cash in lieu of fractional shares, if any, deliverable in respect of each share of CNB Financial Common Stock such shareholder holds, as determined pursuant to Section 2.5 of this Agreement, without any interest thereon. If outstanding Certificates are not surrendered prior to the date on which such payments would otherwise escheat to or become the property of any governmental unit or agency, the unclaimed items shall, to the extent permitted by any abandoned property, escheat or other applicable laws, become the property of Berkshire Hills Bancorp (and, to the extent not in its possession, shall be paid over to it), free and clear of all claims or interest of any person previously entitled to such claims. Notwithstanding the foregoing, neither the Exchange Agent nor any party to this Agreement (or any affiliate thereof) shall be liable to any former holder of CNB Financial Common Stock for any amount delivered to a public official pursuant to applicable abandoned property, escheat or similar laws.

(h) Berkshire Hills Bancorp and the Exchange Agent shall be entitled to rely upon CNB Financial’s stock transfer books to establish the identity of those persons entitled to receive the Merger Consideration, which books shall be conclusive with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate, Berkshire Hills Bancorp and the Exchange Agent shall be entitled to deposit any Merger Consideration and cash in lieu of fractional shares, if any, represented thereby in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

(i) If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Exchange Agent or Berkshire Hills Bancorp, the posting by such person of a bond in such amount as the Exchange Agent may 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 or destroyed Certificate the Merger Consideration and cash in lieu of fractional shares, if any, deliverable in respect thereof pursuant to Section 2.5.

2.7 Effect on Outstanding Shares of Berkshire Hills Bancorp Common Stock. At the Effective Time, each share of common stock of Berkshire Hills Bancorp issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock of the Surviving Corporation and shall not be affected by the Merger.

2.8 Directors of Surviving Corporation After Effective Time.

Subject to Section 5.14, immediately after the Effective Time, until their respective successors are duly elected or appointed and qualified, the directors of the Surviving Corporation shall consist of the directors of Berkshire Hills Bancorp serving immediately prior to the Effective Time.

2.9 Certificate of Incorporation and Bylaws. The certificate of incorporation of Berkshire Hills Bancorp, as in effect immediately prior to the Effective Time, shall be the certificate of incorporation of the Surviving Corporation until thereafter amended in accordance with applicable law. The bylaws of Berkshire Hills Bancorp, as in effect immediately prior to the Effective Time, shall be the bylaws of the Surviving Corporation until thereafter amended in accordance with applicable law.

2.10 Treatment of Stock Options and Warrants.

(a) Each option to purchase shares of CNB Financial Common Stock issued by CNB Financial and outstanding at the Effective Time pursuant to the CNB Financial Amended and Restated Stock Option Plan (formerly, the Commonwealth National Bank 2001 Stock Option Plan) or the CNB Financial Corp. 2008 Equity Incentive Plan (each, a “CNB Financial Option”) shall be converted into an option to purchase shares of Berkshire Hills Bancorp Common Stock as follows:

(i) The aggregate number of shares of Berkshire Hills Bancorp Common Stock issuable upon the exercise of the converted CNB Financial Option after the Effective Time shall be equal to the product of the Exchange Ratio multiplied by the number of shares of CNB Financial Common Stock issuable upon exercise of the CNB Financial Option immediately prior to the Effective Time, such product to be rounded to the nearest whole share of Berkshire Hills Common Stock; and

(ii) the exercise price per share of each converted CNB Financial Option shall be equal to the quotient of the exercise price of such CNB Financial Option immediately prior to the Effective Time divided by the Exchange Ratio, such quotient to be rounded to the nearest whole cent; provided, however, that, in the case of any CNB Financial Option that is intended to qualify as an incentive stock option under Section 422 of the IRC, the number of shares of Berkshire Hills Bancorp Common Stock issuable upon exercise of and the exercise price per share for such converted CNB Financial Option determined in the manner provided above shall be further adjusted in such manner as may be necessary to conform to the requirements of Section 424(b) of the IRC.

Options to purchase shares of Berkshire Hills Bancorp Common Stock that arise from the operation of this Section 2.10 shall be referred to as “Converted Options.” All Converted Options shall be exercisable for the same period and shall otherwise have the same terms and conditions applicable to the CNB Financial Options that they replace.

(b) Before the Effective Time, Berkshire Hills Bancorp will take all corporate action necessary to reserve for future issuance a sufficient additional number of shares of Berkshire Hills Bancorp Common Stock to provide for the satisfaction of its obligations with respect to the Converted Options. Berkshire Hills Bancorp agrees to file, as soon as practicable after the Effective Time, a registration statement on Form S-8 (or any successor or other appropriate form) and make any state filings or obtain state exemptions with respect to the Berkshire Hills Bancorp Common Stock issuable upon exercise of the Converted Options.

(c) Each member of the board of directors of CNB Financial or a CNB Financial Subsidiary who holds outstanding warrants issued by Commonwealth National Bank on November 19, 2001 (each a “CNB Financial Warrant”) shall agree to the cancellation of such CNB Financial Warrant, without consideration, effective immediately prior to the Effective Time. All other CNB Financial Warrants shall be converted to warrants to purchase shares of Berkshire Hills Bancorp Common Stock on the same basis as CNB Financial Options are so converted under Section 2.10(a) above.

2.11 Dissenters’ Rights. Notwithstanding any other provision of this Agreement to the contrary, shares of CNB Financial Common Stock that are outstanding immediately prior to the Effective Time and which are held by shareholders who shall have not voted in favor of the Merger or consented thereto in writing and who properly shall have demanded payment of the fair value for such shares in accordance with the MBCA (collectively, the “Dissenters’ Shares”) shall not be converted into or represent the right to receive the Merger Consideration. Such shareholders instead shall be entitled to receive payment of the fair value of such shares held by them in accordance with the provisions of the MBCA, except that all Dissenters’ Shares held by shareholders who shall have failed to perfect or who effectively shall have withdrawn or otherwise lost their rights as dissenting shareholders under the MBCA shall thereupon be deemed to have been converted into and to have become exchangeable, as of the Effective Time, for the right to receive, without any interest thereon, the Merger Consideration upon surrender in the manner provided in Section 2.6 of the Certificate(s) that, immediately prior to the Effective Time, evidenced such shares. CNB Financial shall give Berkshire Hills Bancorp (i) prompt notice of any written demands for payment of fair value of any shares of CNB Financial Common Stock, attempted withdrawals of such demands and any other instruments served pursuant to the MBCA and received by CNB Financial relating to shareholders’ dissenters’ rights and (ii) the opportunity to participate in all negotiations and proceedings with respect to demands under the MBCA consistent with the obligations of CNB Financial thereunder. CNB Financial shall not, except with the prior written consent of Berkshire Hills Bancorp, (x) make any payment with respect to such demand, (y) offer to settle or settle any demand for payment of fair value or (z) waive any failure to timely deliver a written demand for payment of fair value or timely take any other action to perfect payment of fair value rights in accordance with the MBCA.

2.12 Bank Merger. Concurrently with or as soon as practicable after the execution and delivery of this Agreement, Berkshire Bank, a wholly owned subsidiary of Berkshire Hills Bancorp, and Commonwealth National Bank (“Commonwealth National Bank”), a wholly owned subsidiary of CNB Financial, shall enter into the Plan of Bank Merger, in the form attached hereto as Exhibit B, pursuant to which Commonwealth National Bank will merge with and into Berkshire Bank (the “Bank Merger”). The parties intend that the Bank Merger will become effective simultaneously with or immediately following the Effective Time.

2.13 Alternative Structure.

Any such disclosures were made in writing by management to CNB Financial’s auditors and audit committee.

Neither CNB Financial nor any Subsidiary has been notified that principal and interest with respect to any such loan or other credit accommodation will not be paid when due or that the loan grade classification accorded such loan or credit accommodation by CNB Financial is inappropriate.

(a) Upon reasonable notice, CNB Financial shall (and shall cause its Subsidiaries to) afford Berkshire Hills Bancorp and its representatives (including, without limitation, directors, officers and employees of Berkshire Hills Bancorp and its affiliates and counsel, accountants and other professionals retained by it) such reasonable access during normal business hours throughout the period prior to the Effective Time to the books, records (including, without limitation, tax returns and work papers of independent auditors), contracts, properties, personnel and to such other information as may reasonably be requested; provided, however, that no investigation pursuant to this Section 5.3 shall affect or be deemed to modify any representation or warranty made by CNB Financial in this Agreement.

CNB Financial and Berkshire Hills Bancorp shall furnish each other with all information concerning themselves, their respective subsidiaries, and their and their respective subsidiaries’ directors, officers and shareholders and such other matters as may be reasonably necessary or advisable in connection with any application, notice or filing made by or on behalf of Berkshire Hills Bancorp, CNB Financial or any of their respective subsidiaries to any Governmental Entity in connection with the transactions contemplated by this Agreement and the Plan of Bank Merger.

5.5 Anti-takeover Provisions. CNB Financial and its Subsidiaries shall take all steps required by any relevant federal or state law or regulation or under any relevant agreement or other document to exempt or continue to exempt Berkshire Hills Bancorp, Berkshire Bank, the Agreement, the Plan of Bank Merger and the Merger from any provisions of an anti-takeover nature in CNB Financial’s or its Subsidiaries’ articles of organization and bylaws, or similar organizational documents, and the provisions of any federal or state anti-takeover laws.

5.6 Additional Agreements. Subject to the terms and conditions herein provided, each of the parties hereto agrees to use all reasonable efforts to take promptly, or cause to be taken promptly, all actions and to do promptly, or cause to be done promptly, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement as expeditiously as possible, including using efforts to obtain all necessary actions or non-actions, extensions, waivers, consents and approvals from all applicable Governmental Entities, effecting all necessary registrations, applications and filings (including, without limitation, filings under any applicable state securities laws) and obtaining any required contractual consents and regulatory approvals.

5.8 CNB Financial Shareholder Meeting. CNB Financial will submit to its shareholders this Agreement and any other matters required to be approved or adopted by shareholders in order to carry out the intentions of this Agreement. In furtherance of that obligation, CNB Financial will take, in accordance with applicable law and its articles of organization and bylaws, all action necessary to call, give notice of, convene and hold a meeting of its shareholders (the “Shareholder Meeting”) as promptly as practicable for the purpose of considering and voting on approval and adoption of this Agreement and the transactions provided for in this Agreement. CNB Financial’s Board of Directors will use all reasonable best efforts to obtain from its shareholders a vote approving this Agreement. Except as provided in this Agreement, (i) CNB Financial’s Board of Directors shall recommend to its shareholders approval of this Agreement, (ii) the Proxy Statement-Prospectus shall include a statement to the effect that CNB Financial’s Board of Directors have recommended that its shareholders vote in favor of the approval of this Agreement and (iii) neither CNB Financial’s Board of Directors nor

any committee thereof shall withdraw, amend or modify, or propose or resolve to withdraw, amend or modify, the recommendation of CNB Financial’s Board of Directors that its shareholders vote in favor of approval of this Agreement or make any statement in connection with the Shareholder Meeting inconsistent with such recommendation (collectively, a “Change in Recommendation”). Notwithstanding the foregoing, if (x) CNB Financial has complied in all material respects with its obligations under Section 5.1, (y) CNB Financial (1) has received an unsolicited bona fide written Acquisition Proposal from a third party that CNB Financial’s Board of Directors concludes in good faith constitutes a Superior Proposal after giving effect to all of the adjustments that may be offered by Berkshire Hills Bancorp pursuant to clause (3) below, (2) has notified Berkshire Hills Bancorp, at least five business days in advance, of it is intention to effect a Change in Recommendation, specifying the material terms and conditions of any such Superior Proposal and furnishing to Berkshire Hills Bancorp a copy of the relevant proposed transaction documents, if such exist, with the person making such Superior Proposal and (3) during the period of not less than five business days following CNB Financial’s delivery of the notice referred to in clause (2) above and prior to effecting such Change in Recommendation, has negotiated, and has used reasonable best efforts to cause its financial and legal advisors to negotiate, with Berkshire Hills Bancorp in good faith (to the extent that Berkshire Hills Bancorp desires to negotiate) to make such adjustments in the terms and conditions of this Agreement so that such Acquisition Proposal ceases to constitute a Superior Proposal and (z) CNB Financial’s Board of Directors, after consultation with and based on the advice of counsel, determines in good faith that it would result in a violation of its fiduciary duties under applicable law to recommend this Agreement, then in submitting the Agreement to shareholders at the Shareholder Meeting it may submit the Agreement without recommendation, or following submission of the Agreement to shareholders it may withdraw, amend or modify its recommendation, in which case the Board of Directors may communicate the basis for its lack of a recommendation, or the withdrawal, amendment or modification of its recommendation, to the shareholders in the Proxy Statement-Prospectus or an appropriate amendment or supplement thereto to the extent required by law.

5.9 Registration of Berkshire Hills Bancorp Common Stock.

(a) As promptly as reasonably practicable following the date hereof, Berkshire Hills Bancorp shall prepare and file with the SEC a registration statement on Form S-4 with respect to the issuance of Berkshire Hills Bancorp Common Stock in the Merger (such Form S-4, and any amendments or supplements thereto, the “Registration Statement”). The Registration Statement shall contain proxy materials relating to the matters to be submitted to the CNB Financial shareholders at the Shareholder Meeting, which shall also constitute the prospectus relating to the shares of Berkshire Hills Bancorp Common Stock to be issued in the Merger (such proxy statement/prospectus, and any amendments or supplements thereto, the “Proxy Statement-Prospectus”). CNB Financial will furnish to Berkshire Hills Bancorp the information required to be included in the Registration Statement with respect to its business and affairs and shall have the right to review and consult with Berkshire Hills Bancorp and approve the form of, and any characterizations of such information included in, the Registration Statement prior to its being filed with the SEC. Berkshire Hills Bancorp shall use reasonable best efforts to have the Registration Statement declared effective by the SEC and to keep the Registration Statement effective as long as is necessary to consummate the Merger and the transactions contemplated hereby. Berkshire Hills Bancorp and CNB Financial will each use

reasonable best efforts to cause the Proxy Statement-Prospectus to be mailed to the shareholders of CNB Financial as promptly as practicable after the Registration Statement is declared effective under the Securities Act. Berkshire Hills Bancorp will advise CNB Financial, promptly after it receives notice thereof, of the time when the Registration Statement has become effective, the issuance of any stop order, the suspension of the qualification of the Berkshire Hills Bancorp Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction, or any request by the SEC for amendment of the Proxy Statement-Prospectus or the Registration Statement. If at any time prior to the Effective Time any information relating to Berkshire Hills Bancorp or CNB Financial, or any of their respective affiliates, officers or directors, should be discovered by Berkshire Hills Bancorp or CNB Financial which should be set forth in an amendment or supplement to any of the Registration Statement or the Proxy Statement-Prospectus so that any of such documents would not include any misstatement of a material fact or omit to state any material fact necessary to make the statements therein, in light of the circumstances under which they were made, not misleading, the party which discovers such information shall promptly notify the other party hereto and, to the extent required by law, rules or regulations, an appropriate amendment or supplement describing such information shall be promptly filed by Berkshire Hills Bancorp with the SEC and disseminated by CNB Financial to the shareholders of CNB Financial.

(b) Berkshire Hills Bancorp shall also take any action required to be taken under any applicable state securities laws in connection with the Merger and each of CNB Financial and Berkshire Hills Bancorp shall furnish all information concerning it and the holders of CNB Financial Common Stock as may be reasonably requested in connection with any such action.

5.11 Employee Benefit Matters.

(a) All persons who are employees of Commonwealth National Bank immediately prior to the Effective Time and whose employment is not specifically terminated at

Except for those persons who enter into an employment agreement with Berkshire Bank, all of the Continuing Employees shall be employed at the will of Berkshire Bank and no contractual right to employment shall inure to such employees because of this Agreement.

(d) Each employee of CNB Financial or a Subsidiary who has been employed by CNB Financial or a Subsidiary for twelve months prior to the Effective Time, except any employee who is a party to a change in control agreement with CNB Financial or a Subsidiary, shall be entitled upon an involuntary termination of employment (other than for “Just Cause”) or a voluntary termination of employment for any reason listed in Section 4.2 of the Berkshire Bank Employee Severance Compensation Plan (the “Severance Plan”) occurring at the Effective Time or within one year following the Effective Time, to a severance payment equal to one-twelfth (1/12^th) of his or her “Annual Compensation” for each year of service with CNB Financial or a Subsidiary up to 199% of his or her Annual Compensation, reduced, if necessary, to avoid an “excess parachute payment” within the meaning of IRC Section 280G. For these purposes, “Annual Compensation” and “Just Cause” shall have the same meanings as provided for in Sections 2.1(a) and 2.1(j), respectively of the Severance Plan. Any payment of severance shall be made not later than twenty business days following the individual’s termination of employment.

(e) Berkshire Hills Bancorp shall honor all obligations under the change-in-control agreements as set forth in CNB Financial’s Disclosure Letter.

(b) Any Indemnified Party wishing to claim indemnification under Section 5.12(a), upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify Berkshire Hills Bancorp thereof, but the failure to so notify shall not relieve Berkshire Hills Bancorp of any liability it may have hereunder to such Indemnified Party if such failure does not materially and substantially prejudice Berkshire Hills Bancorp.

(c) Berkshire Hills Bancorp shall use its reasonable best efforts to maintain CNB Financial’s existing directors’ and officers’ liability insurance policy (or provide a policy providing comparable coverage and amounts on terms no less favorable to the persons currently covered by CNB Financial’s existing policy, including Berkshire Hills Bancorp’s existing policy if it meets the foregoing standard) covering persons who are currently covered by such insurance for a period of six years after the Effective Time; provided, however, that in no event shall

Berkshire Hills Bancorp be obligated to expend, in order to maintain or provide insurance coverage pursuant to this Section 5.12(c), an amount in the aggregate in excess of 150% of the amount of the annual premiums paid by CNB Financial as of the date hereof for such insurance (“Maximum Insurance Amount”); provided further, that if the amount of the premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Insurance Amount, Berkshire Hills Bancorp shall obtain the most advantageous coverage obtainable for a premium equal to the Maximum Insurance Amount.

8.8 Entire Agreement; etc. This Agreement, together with the Exhibits and the Disclosure Letters, represents the entire understanding of the parties hereto with reference to the transactions contemplated hereby and supersedes any and all other oral or written agreements heretofore made. All terms and provisions of this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and assigns.

8.10 Specific Performance. Each of the parties hereto acknowledges that the other party would be irreparably damaged and would not have an adequate remedy at law for money damages in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Each of the parties hereto therefore agrees that, without the necessity of proving actual damages or posting bond or other security, the other party shall be entitled to temporary or permanent injunction or injunctions to prevent breaches of such performance and to enforce specifically the terms and provisions of this Agreement in addition to any other remedy to which they may be entitled, at law or in equity.
