Forward-Looking Statements and Cautionary Statements

This news release contains certain statements and information that may constitute “forward-looking statements.” All statements, other than statements of historical fact, which address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements. The words “anticipate,” “believe,” “expect,” “plan,” “forecasts,” “will,” “could,” “may,” and similar expressions that convey the uncertainty of future events or outcomes, and the negative thereof, are intended to identify forward-looking statements. Forward-looking statements, which are not generally historical in nature, include those that express a belief, expectation or intention regarding our future activities, plans and goals. Forward-looking statements are not assurances of future performance and actual results could differ materially from our historical experience and our present expectations or projections. Our forward-looking statements involve significant risks, contingencies and uncertainties, most of which are difficult to predict and many of which are beyond our control. Known material factors that could cause actual results to differ materially from those in the forward-looking statements are listed in our filings with the SEC. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date hereof. We undertake no obligation to publicly update or revise any forward-looking statements after the date they are made, whether as a result of new information, future events or otherwise, except as required by law.
