Forward-Looking Statements

Certain statements in this press release constitute "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, Section 21E of the Securities Exchange Act of 1934, as amended, and the safe harbor from liability established by the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical facts may be forward-looking statements. Forward-looking statements include, but are not limited to, statements regarding the Company's current expectations and views with respect to, among other things, the offering. In some cases, you can identify forward-looking statements by terms such as "anticipates," "believes," "contemplates," "continue," "could," "estimates," "expects," "intends," "may," "plans," "potential," "predicts," "projects," "should," "targets," "will," "would" or the negative of these terms or other similar expressions. Forward-looking statements are neither historical facts nor assurances of future performance, and are based only on our current beliefs, expectations and assumptions regarding the future of our business, future plans and strategies, projections, anticipated events and trends, the economy and other future conditions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that are difficult to predict and many of which are outside of our control. Therefore, you should not rely on any of these forward-looking statements. Important factors that could cause our actual results and financial condition to differ materially from those indicated in the forward-looking statements include, among others, the risks described in our reports filed with the SEC. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements.
