Berkshire Hills Bancorp expects to issue approximately 980,000 shares of Berkshire Hills Bancorp common stock in connection with the transaction, not including any shares issued as a result of the exercise of CNB Financial stock options which will be exchanged for Berkshire Hills Bancorp stock options. The other terms and provisions of the Merger Agreement are not affected by the Amendment and remain unchanged.
