Caution Concerning

Forward-Looking

Statements

This presentation includes "forward-looking statements" with the meaning of Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the U.S. Securities Exchange Act of 1934, as amended.

All forward-looking statements are subject to a number of risks, uncertainties and assumptions, and you should not rely upon forward-looking statements as predictions of future events. You can identify forward-looking statements by words such as "anticipate," "believe," "could," "estimate," "expect," "intend," "may," "plan," "potential," "predict," "project," "should," "will," "would," or the negative

of those terms, and similar expressions that convey uncertainty of future events or outcomes.

All forward-looking statements are based upon current estimates and expectations about future events and financial and other trends. There is no guarantee that future results, performance, or events reflected in the forward-looking statements will be achieved or occur.

Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, actual results may vary in material respects from those projected in these forward-looking statements. No person assumes responsibility for the accuracy and completeness of the forward-looking statements, and, except as required by law, no person undertakes any obligation to update any forward-looking statements for any reason after the date of this company presentation.

Non-GAAP Financial Measures

In addition to financial results prepared in accordance with U.S. generally accepted accounting principles ("GAAP"), this presentation contains certain non-GAAP financial measures. Such non-GAAP financial measures in this presentation may differ from similarly named non-GAAP financial measures used by other companies. Management believes that

in addition to using GAAP results, non-GAAP financial measures can provide meaningful insight in evaluating the Company's operating performance.

For a full discussion of the Company's risks, you should review the Company's most recent SEC filings including the Company's most recent 10-K and 10-Q available on SEC.gov
