Forward Looking Statements. This document contains certain forward-looking statements as defined in the Private Securities Litigation Reform Act of 1995. These statements include statements about anticipated financial results. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. They often include words like "believe," "expect," "anticipate," "estimate," and "intend" or future or conditional verbs such as "will," "would," "should," "could" or "may.“ There are several factors that could cause actual results to differ significantly from expectations described in the forward-looking statements. For a discussion of such factors, please see Berkshire’s most recent reports on Forms 10-K and 10-Q filed with the Securities and Exchange Commission and available on the SEC's website at www.sec.gov. Berkshire does not undertake any obligation to update forward-looking statements made in this document. NON-GAAP FINANCIAL MEASURES. This presentation references non-GAAP financial measures incorporating tangible equity and related measures, and core earnings excluding merger and other non-recurring costs. These measures are commonly used by investors in evaluating business combinations and financial condition. GAAP earnings are lower than core earnings primarily due to merger and systems conversion related expenses. Reconciliations are in earnings releases at www.berkshirebank.com. 10
