Forward-Looking Statements
 
This communication contains "forward-looking statements", including as defined
under U.S. federal securities laws. Forward-looking statements provide the
Company's current expectations or forecasts of future events. Forward-looking
statements include statements about the Company's expectations, beliefs, plans,
objectives, intentions, assumptions and other statements that are not historical
facts or that are not present facts or conditions. Words or phrases such as
"anticipate," "believe," "continue," "estimate," "expect," "hope," "intend,"
"may," "ongoing," "plan," "potential," "predict," "project," "should," "will" or
similar words or phrases, or the negatives of those words or phrases, may
identify forward-looking statements, but the absence of these words does not
necessarily mean that a statement is not forward-looking. Forward-looking
statements are subject to known and unknown risks and uncertainties and are
based on potentially inaccurate assumptions that could cause actual results to
differ materially from those expected or implied by the forward-looking
statements. The Company's actual results could differ materially from those
anticipated in forward-looking statements for many reasons, including as
described in the Company's filings with the U.S. Securities and Exchange
Commission. Accordingly, you should not unduly rely on these forward-looking
statements, which speak only as of the date of this communication. Factors that
could cause actual results to differ materially include, but are not limited to,
the Company's operating or financial results
