          (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.

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.

               (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.

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.

amount or kind of the Merger Consideration or (ii) materially impede or delay the receipt of any regulatory approval referred to in, or the consummation of the transactions contemplated by, this Agreement. In the event that Berkshire Hills Bancorp elects to make such a revision, the parties agree to execute appropriate documents to reflect the revised structure.

      2.14 Absence of Control .
