This press release contains forward-looking statements, which are based upon
the current expectations of the Company. Because these forward-looking
statements are inherently subject to risks and uncertainties, there are a
number of factors that could cause the Company's plans, actions and actual
results to differ materially. Among these factors are the Company's ability
to: re-activate its formerly idle manufacturing facilities on a timely and
cost-effective basis, to meet current order levels for carbon fibers;
successfully add new capacity for the production of carbon fiber and
precursor raw material; execute plans to exit its specialty products
business and reduce costs; achieve profitable operations; raise new capital
and increase its borrowing at acceptable costs; manage changes in customers'
forecasted requirements for the Company's products; continue investing in
application and market development; manufacture low-cost carbon fibers and
profitably market them; and penetrate existing, identified and emerging
markets. The timing and occurrence (or non-occurrence) of transactions and
events that determine the future effect of these factors on the Company, as
well as other factors, may be beyond the control of the Company. The Company
undertakes no obligation to update any forward-looking statement to reflect
events or circumstances after the date of this press release.
