These may include statements as to the benefits of the merger, including future financial and operating results, cost savings, enhanced revenues and the accretion/dilution to reported earnings that may be realized from the merger as well as other statements of expectations regarding the merger and any other statements regarding future results or expectations. Each of First Busey and Main Street intends such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and is including this statement for purposes of these safe harbor provisions. Forward-looking statements, which are based on certain assumptions and describe future plans, strategies, and expectations of each of First Busey and Main Street, are generally identified by the use of words such as “believe,” “expect,” “intend,” “anticipate,” “estimate,” or “project” or similar expressions. The companies’ respective ability to predict results, or the actual effect of future plans or strategies, is inherently uncertain. Factors which could have a material adverse effect on the operations and future prospects of each of First Busey and Main Street and their respective subsidiaries include, but are not limited to: the risk that the businesses of First Busey and/or Main Street in connection with the merger will not be integrated successfully or such integration may be more difficult, time-consuming or costly than expected; expected revenue synergies and cost savings from the merger may not be fully realized or realized within the expected time frame; revenues following the merger may be lower than expected; customer and employee relationships and business operations may be disrupted by the merger; the ability to obtain required governmental and stockholder approvals, and the ability to complete the merger on the expected timeframe; changes in interest rates, general economic conditions, legislative/regulatory changes, monetary and fiscal policies of the U.S. government, including policies of the U.S. Treasury and the Federal Reserve Board; the quality and composition of the loan or securities portfolios; demand for loan products; deposit flows; competition; demand for financial services in the companies’ respective market areas; their implementation of new technologies; their ability to develop and maintain secure and reliable electronic systems; and accounting principles, policies, and guidelines. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements.
