Forward-Looking Statements

This presentation contains certain forward-looking information about California United Bank that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. Such statements involve inherent risks and uncertainties, many of which are difficult to predict and are generally beyond the control of the Bank. There are a number of important factors that could cause actual results to differ materially from those expressed in, implied or projected by, such forward-looking statements. Risks and uncertainties include but are not limited to lower than expected revenues; credit quality deterioration which could cause an increase in the allowance for loan losses and a reduction in net earnings; increased competitive pressure among depository institutions; a change in the interest rate environment which reduces interest margins; asset/liability repricing risks and liquidity risks; general economic conditions, either nationally or in the market areas in which the Bank does or anticipates doing business are less favorable than expected; environmental conditions, including natural disasters, may disrupt our business, impede our operations, negatively impact the values of collateral security for the Bank’s loans or impair the ability of our borrowers to support their debt obligations; the economic and regulatory effects of the continuing war on terrorism and other events of war; legislative or regulatory requirements or changes adversely affecting the Bank’s business; and changes in the securities markets. If any of these risks or uncertainties materializes or if any of the assumptions underlying such forward-looking statements proves to be incorrect, California United Bank’s results could differ materially from those expressed in, implied or projected by such forward-looking statements. California United Bank assumes no obligation to update such forward-looking statements. For a more complete discussion of risks and uncertainties, read the Bank’s annual report on Form 10-K, quarterly reports on Form 10-Q and other reports filed by the Bank with the FDIC. The documents filed with the FDIC may be obtained at California United Bank’s website at www.californiaunitedbank.com.
