This presentation contains forward - looking statements . Any statements about our expectations, beliefs, plans, predictions, forecasts, objectives, assumptions or future events or performance are not historical facts and may be forward - looking .

Accordingly, these statements are only predictions and involve estimates, known and unknown risks, assumptions and uncertainties that could cause actual results to differ materially from those expressed in them . Our actual results could differ materially from those anticipated in such forward - looking statements as a result of several factors more fully described under “Risk Factors” in our Annual Report on Form 10 - K, Item 1 A, filed with the Securities and Exchange Commission . Any or all of our forward - looking statements in this presentation may turn out to be inaccurate . The inclusion of this forward - looking information should not be regarded as a representation by us that the future plans, estimates or expectations contemplated by us will be achieved . We have based these forward - looking statements largely on our current expectations and projections about future events and financial trends that we believe may affect our financial condition, results of operations, business strategy and financial needs . There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from the results, level of activity, performance or achievements expressed or implied by the forward looking statements including, but not limited to the risk factors described above and : ( 1 ) changes in general economic and financial market conditions ; ( 2 ) changes in the regulatory environment ; ( 3 ) economic conditions generally and in the financial services industry ; ( 4 ) changes in the economy affecting real estate values ; ( 5 ) our ability to achieve loan and deposit growth ; ( 6 ) the completion of our future acquisitions or business combinations and our ability to integrate the acquired business into our business model ; ( 7 ) projected population and income growth in our targeted market areas ; and ( 8 ) volatility and direction of market interest rates and a weakening of the economy which could materially impact credit quality trends and the ability to generate loans . All forward - looking statements are necessarily only estimates of future results and actual results may differ materially from expectations . You are, therefore, cautioned not to place undue reliance on such statements which should be read in conjunction with the other cautionary statements that are included elsewhere in this presentation . Further, any forward - looking statement speaks only as of the date on which it is made and we undertake no obligation to update or revise any forward - looking statement to reflect events or circumstances after the date on which the statement is made or to reflect the occurrence of unanticipated events .
