Cautionary Statements

This Current Report on Form 8-K, including the exhibits furnished herewith, contains “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Exchange Act. Such forward-looking statements relate to, without limitation, our future economic performance, plans and objectives for future operations and projections of revenue and other financial items. Forward-looking statements can be identified by the use of words such as “may,” “will,” “plan,” “potential,” “should,” “expect,” “anticipate,” “estimate,” “continue” or comparable terminology. Forward-looking statements are inherently subject to risks and uncertainties, many of which we cannot predict with accuracy and some of which we might not even anticipate. Although we believe that the expectations reflected in such forward-looking statements are based upon reasonable assumptions at the time made, we can give no assurance that such expectations will be achieved. Future events and actual results, financial and otherwise, may differ materially from the results discussed in the forward-looking statements as a result of various factors, including those listed in Exhibit 99.1 on page 1 and incorporated by reference herein. Readers are cautioned not to place undue reliance on these forward-looking statements. Unless required by U.S. federal securities laws, we do not intend to update any of the forward-looking statements to reflect circumstances or events that occur after the statements are made or to conform the statements to actual results. The information contained in this Current Report on Form 8-K, including the exhibit filed herewith, should be viewed in conjunction with the consolidated financial statements and notes thereto appearing in the Company’s Annual Report on Form 10-K and Quarterly Report on Form 10-Q.
