CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

This Annual Report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities and Exchange Act of 1934, as amended (the “Exchange Act”). We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation Reform Act of 1995 and include this statement for purposes of complying with these safe harbor provisions.

This document contains certain forward-looking statements with respect to our financial condition, results of operations and business, plans, objectives and strategies. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as “estimate,” “project,” “predict,” “will,” “would,” “should,” “could,” “may,” “might,” “anticipate,” “plan,” “intend,” “believe,” “expect,” “aim,” “goal,” “target,” “objective,” “commit,” “advance,” “likely” or similar expressions that convey the prospective nature of events or outcomes.

These forward-looking statements reflect our current views with respect to future events and are based on numerous assumptions and assessments made by us in light of our experience and perception of historical trends, current conditions, business strategies, operating environments, future developments and other factors we believe appropriate. By their nature, forward-looking statements involve known and unknown risks and uncertainties because they relate to events and depend on circumstances that will occur in the future. The factors described in the context of such forward-looking statements in this document could cause our plans, actual results, performance or achievements, industry results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are reasonable, we cannot assure you that such expectations will prove to have been correct and persons reading this document are therefore cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this Annual Report. We do not assume any obligation to update the information contained in this document (whether as a result of new information, future events or otherwise), except as required by applicable law.
