Forward Looking Statements
This communication contains "forward-looking statements", including as defined
under applicable laws, such as the US Private Securities Litigation Reform Act
of 1995. 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 SEC. 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
