All statements in this Annual Report, other than statements of historical facts, including, without limitation, statements regarding our strategy, future operations, future operating expenses, future financial position, future revenue, projected costs, prospects, plans, intentions, expectations, goals and objectives may be forward-looking statements. The forward-looking statements in this Annual Report do not constitute guarantees of future performance, and actual results could differ materially from those expressed or implied in any forward-looking statements. In some cases, you can identify forward-looking statements by words such as “believe,” “expect,” “anticipate,” “contemplate,” “estimate,” “project,” “forecast,” “would,” “may,” “should,” “will,” “could,” “can,” “potential,” “possible,” “proposed,” “plan,” “develop,” “opportunity,” “intend,” “initiative,” “target,” “maintain,” “continue,” “strive,” “progress,” “aim,” or the negative of these terms or other comparable expressions.

Factors, among others, that could cause actual results and events to differ materially from those expressed or implied in any forward-looking statement include:

Additional factors that might cause actual results and our current expectations and projections to differ materially include, among other things, those discussed under the section titled “Risk Factors,” as well as those discussed elsewhere in the Annual Report and the other risks detailed from time-to-time in our reports and registration statements filed with the Securities and Exchange Commission, or SEC. We intend that such forward-looking statements be subject to the safe harbors for such statements. These forward-looking statements are based on the current beliefs and expectations of our management and speak only as of the date of this Annual Report or, in the case of documents referred to or incorporated by reference, the date of those documents. You should not place undue reliance on these forward-looking statements, which are subject to significant known and unknown risks, uncertainties and other factors, which are in some cases, beyond our control and which could materially affect results. If underlying assumptions prove inaccurate or unknown risks or uncertainties materialize, actual results may differ materially from current expectations and projections.

Except as required by law, we do not undertake any obligation torevise or update publicly any forward-looking statements, whether as a result of new information, future events or otherwise. If we do update one or more forward-looking statements, no inference should be drawn that we will make additional updates with respect to those or other forward-looking statements.
