Forward-Looking Statements

This news release contains forward-looking statements based on current
expectations that involve a number of risks and uncertainties. Generally,
forward-looking statements include words or phrases such as "management
anticipates," "the Company believes," "the Company anticipates," "the Company
expects," "the Company plans," "the Company will," and words and phrases of
similar impact, and include but are not limited to statements regarding future
operations, business strategy and business environment. The forward-looking
statements are made pursuant to safe harbor provisions of the Private
Securities Litigation Reform Act of 1995. Actual results could differ
materially. Factors that could cause actual results to differ include, but are
not limited to, the following:

o        The decision to re-audit the Company's consolidated financial
         statements for fiscal years 2000 and 2001 will result in the Company
         being required to restate the financial results for one or more prior
         periods.  The re-audit has resulted in the Company's independent
         accountants proposing changes to other items of income and expense
         and the application of accounting principles unrelated to the
         transactions currently under consideration.  The Company is uncertain
         whether the re-audit or restatement of any prior period will have a
         material adverse effect on the Company's customers, suppliers or
         other business relationships.

o        There can be no assurance that the Company will be able to complete
         the re-audit by December 31, 2002. In the event that the Company does
         not complete the re-audit by December 31, 2002 it will not be in
         compliance with the NASDAQ rules, which in turn will most likely cause
         the Company's stock to be de-listed.

For a detailed discussion of these and other risk factors, interested parties
should review the Company's filings with the Securities and Exchange Commission.
