2 Forward Looking Statements The foregoing discussion may include forward-looking statements for purposes of the safe harbor provisions of the Private Securities Litigation Reform Act of Such forward-looking statements are based upon specific assumptions and are subject to uncertainties and factors relating to the company's operations and business environment, all of which are difficult to predict and many of which are beyond the control of the company. These uncertainties and factors could cause actual results of the company to differ materially from those expressed or implied in the forward-looking statements contained in the foregoing discussion. Such uncertainties and factors include: the impact of an adverse result in excess of our insurance coverage in the shareholder class action lawsuits filed against the Company and certain of its executives; the speed and sustainability of price changes in cobalt and nickel; the availability of competitively priced supplies of raw materials, particularly cobalt and nickel; the effect of the restatement, or the effect of our inability to meet our SEC and NYSE filing obligations on a timely basis, upon funding availability under our credit facilities or upon debt obligations outstanding; the effect of the Company not completing the testing of its internal control over financial reporting systems such that management of the Company and its independent auditors are unable to report as to such internal control over financial reporting in a timely fashion for the year 2004; the risk that new or modified internal controls, implemented in response to an investigation by the audit committee of the Company’s board of directors and the Company’s examination of its internal control over financial reporting systems pursuant to Section 404 of the Sarbanes-Oxley Act, are not effective and need to be improved, resulting in additional expense; the demand for metal-based specialty chemicals and products in the Company’s markets; the effect of fluctuations in currency exchange rates on the Company’s international operations; the effect of non-currency risks of investing and conducting operations in foreign countries, including political, social, economic and regulatory factors; the outcome of the previously announced SEC review of the investigation conducted by the Company’s audit committee; and the general level of global economic activity and demand for the company’s products.
