Cautionary Statement Regarding Forward-Looking Statements

This communication contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Any statements about our expectations, beliefs, plans, or future events are not historical facts and may be forward-looking. Such statements include, but are not limited to, the Company’s statements regarding the tender offer. These statements are often, but not always, made through the use of words or phrases such as “anticipates,” “believes,” “can,” “could,” “may,” “predicts,” “potential,” “should,” “will,” “looking forward,” “would,” “hopes,” “assumes,” “estimates,” “plans,” “projects,” “continuing,” “ongoing,” “expects,” “intends,” and similar words or phrases. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date on which the statements are made, these statements are not guarantees of future performance and involve risks and uncertainties that are subject to change based on various important factors and assumptions, some of which are beyond our control. For additional discussion of these risks, refer to the section entitled “Risk Factors” and elsewhere in our Annual Report on Form 10-K we file with the Securities and Exchange Commission (the “SEC”). Among the factors that could cause actual results to differ from those reflected in forward-looking statements include, without limitation, the risks and uncertainties described in the Company’s filings with the SEC. New risks and uncertainties emerge from time to time, and it is not possible for the Company to predict all risks and uncertainties that could have an impact on the forward-looking statements contained in this communication. In light of the significant uncertainties inherent in the forward-looking information included herein, the inclusion of such information should not be regarded as a representation by the Company or any other person that the Company’s expectations, objectives or plans will be achieved in the timeframe anticipated or at all. Investors are cautioned not to place undue reliance on the Company’s forward-looking statements, and the Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law. Any forward-looking statements only speak as of the date of this document, and we undertake no obligation to update any forward-looking information or statements, whether written or oral, to reflect any change, except as required by law.
