                           FORWARD-LOOKING STATEMENTS
                           --------------------------

This document may contain statements, estimates or projections that constitute
"forward-looking" statements as defined under U.S. federal securities laws.
Generally the words "believe," "expect," "intend," "estimate," "anticipate,"
"project," "will" and similar expressions identify forward-looking statements,
which generally are not historical in nature. By their nature, forward-looking


statements are subject to risks and uncertainties that could cause actual
results to differ materially from our historical experience and our present
expectations or projections. A list and description of some of the risks and
uncertainties can be found in our reports filed with the SEC from time to time,
including our annual reports on Form 10-K, quarterly reports on Form 10-Q and
current reports on Form 8-K. You should not place undue reliance on
forward-looking statements, which speak only as of the date they are made.
Except to the extent otherwise required by federal securities laws, we do not
undertake to publicly update or revise any forward-looking statements.
