These statements speak only as of the date they are made. The companies undertake no obligation to revise or publicly release any revision or update to these forward-looking statements to reflect events or circumstances that occur after the date on which such statements were made.

They often include words like “believe,” “expect,” “anticipate,” “estimate,” and “intend” or future or conditional verbs such as “will,” “would,” “should,” “could” or “may.” Certain factors that could cause actual results to differ materially from expected results include delays in completing the merger, difficulties in achieving cost savings from the merger or in achieving such cost savings within the expected time frame, difficulties in integrating the Company and Pamrapo, increased competitive pressures, changes in the interest rate environment, changes in general economic conditions, legislative and regulatory changes that adversely affect the business in which the Company and Pamrapo are engaged, changes in the securities markets and other risks and uncertainties disclosed from time to time in documents that the Company and Pamrapo file with the Securities and Exchange Commission (the “SEC”).
