Forward-looking statementsreflect our current views with respect to, among other things, our operations and financial performance. All statements other thanstatements of historical facts contained in this Quarterly Report on Form 10-Q are forward-looking statements.

Forward-looking statements inherently involve many risks and uncertainties that could cause actualresults to differ from those expressed in forward-looking statements. Forward-looking statements are based on management’s currentplans and expectations, expressed in good faith and believed to have a reasonable basis. However, we can give no assurance that anyexpectation or belief will result or will be achieved or accomplished. Investors therefore should not place undue reliance on forward-looking statements.
