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
