TABLE OF CONTENTS

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

This annual report on Form 20-F, or this Annual Report, and any other written or oral statements made by us or on our behalf may include forward-looking statements, which reflect our current views with respect to future events and financial performance. Forward-looking statements include statements concerning plans, objectives, goals, strategies, future events or performance, and underlying assumptions and other statements, which are statements other than statements of historical facts. When used in this Annual Report, statements that are predictive in nature, that depend upon or refer to future events or conditions, or that include words such as “anticipate,” “believe,” “expect,” “intend,” “estimate,” “forecast,” “project,” “plan,” “potential,” “continue,” “seeks,” “views,” “possible,” “likely,” “may,” “should,” and similar words, phrases, or expressions identify forward-looking statements, and the negatives of those words, phrases, or expressions, or statements that events, conditions, or results “can,” “will,” “may,” “must,” “would,” “could,” or “should” occur or be achieved and similar expressions in connection with any discussion, expectation, or projection of future operating or financial performance, costs, regulations, events, or trends identify forward-looking statements. The absence of these words does not necessarily mean that a statement is not forward-looking. As a result, you are cautioned not to rely on any forward-looking statements.

The forward-looking statements in this Annual Report are based upon various assumptions, many of which are based, in turn, upon further assumptions, including without limitation, management’s examination of historical operating trends, data contained in our records, and other data available from third parties. Although we believe that these assumptions were reasonable when made, because these assumptions are inherently subject to significant uncertainties and contingencies that are difficult or impossible to predict and are beyond our control, we cannot assure you that we will achieve or accomplish these expectations, beliefs, or projections.

In addition to these assumptions and matters discussed elsewhere herein and, in the documents, incorporated by reference herein, important factors that, in our view, could cause actual results to differ materially from those discussed in the forward-looking statements include the following:

The preceding list is not intended to be an exhaustive list of all our forward-looking statements. These factors could cause actual results or developments to differ materially from those expressed in any of our forward-looking statements. Other unknown or unpredictable factors also could harm our results or developments. Consequently, there can be no assurance that actual results or developments anticipated by us will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, us. Given these uncertainties, prospective investors are cautioned not to place undue reliance on such forward-looking statements. All forward-looking statements in this Annual Report are qualified in their entirety by the cautionary statements contained in this Annual Report.

Any forward-looking statements contained herein are made only as of the date of this Annual Report, and except to the extent required by applicable law or regulation, we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which such statement is made or to reflect the occurrence of unanticipated events. If one or more forward-looking statements are updated, no inference should be drawn that additional updates will be made with respect to those or other forward-looking statements. New factors emerge from time to time, and it is not possible for us to predict all or any of these factors. Further, we cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward-looking statement.
