Forward Looking Statements

Except for the historical and factual information contained herein, the matters set forth in this report, including statements regarding the terms of the offering, the anticipated use of the proceeds therefrom and other statements identified by words such as “expects,” “will,” “intends,” and similar expressions are forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are subject to a number of risks and uncertainties that may cause actual events and results to differ materially from those anticipated, estimated, projected, expressed or implied if one or more of these risks or uncertainties materialize, or if underlying assumptions prove incorrect. Factors that could affect actual results include but are not limited to: satisfaction of each of the conditions to the underwriters’ obligation to consummate the offering; corporate developments that could preclude, impair or delay the consummation of the offering due to restrictions under the federal securities laws; changes in our cash requirements, financial position, financing plans or investment plans; changes in general market, economic, regulatory or industry conditions; and other risks referenced from time to time in our filings with the Securities and Exchange Commission. Due to the above-listed uncertainties, there can be no assurances that the above-described offering will be consummated on the terms described above or at all. You should be aware that new factors may emerge from time to time and it is not possible for us to identify all such factors, nor can we predict the impact of each such factor on our plans, or the extent to which any one or more factors may cause actual results to differ from those reflected in any of our forward-looking statements. Accordingly, you are cautioned not to place undue reliance upon any of our forward-looking statements, which speak only as of the date made. We undertake no obligation to update or revise for any reason any forward-looking statements made by us or on our behalf, whether as a result of new information, future events or developments, changed circumstances or otherwise.
