Disclosure Regarding Forward-Looking Statements

Certain statements contained herein are forward-looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995, which reflect management’s expectations relating to future business opportunities and expected contributions of the Trax business to the Company’s future financial results. These forward-looking statements are based on the beliefs of Company management, as well as assumptions and estimates based on information available to the Company as of the dates such assumptions and estimates are made, and are subject to certain risks and uncertainties that could cause actual results to differ materially from historical results or those anticipated, depending on a variety of factors. For a discussion of these and other risks and uncertainties, refer to our most recent Annual Report on Form 10-K, Part I, “Item 1A, Risk Factors” and our subsequent Quarterly Reports on Form 10-Q. These events and uncertainties are difficult or impossible to predict accurately and many are beyond the Company’s control. The risks described in these reports are not the only risks the Company faces, as additional risks and uncertainties are not currently known or foreseeable or impossible to predict accurately or risks that are beyond the Company’s control or deemed immaterial may materially adversely affect our business, financial condition or results of operations in future periods. The Company assumes no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.
