(a)	EBITDA represents, for any relevant period, income (loss) before income taxes, depreciation of property, plant and equipment, net interest expense (including amortization of debt issuance costs and warrant interest income) and amortization of intangible assets.
(b)	Adjusted EBITDA represents, for any relevant period, income (loss) before income taxes, depreciation of property, plant and equipment, net interest expense, amortization of debt issuance costs, amortization of intangible assets, impairment of intangible assets, restructuring costs, and gains and losses on both foreign exchange and sale of assets. Adjusted EBITDA for fourth quarter of fiscal year 2002 and full fiscal year 2002 exclude as a separate component other income of $0.5 million and $1.1 million recognized on the dissolution of a joint venture and recovery with respect to a promissory note payable to the Company, respectively. Adjusted EBITDA for the full fiscal year 2003 excludes restructuring costs of $0.4 million.
(c)	EBITDA and Adjusted EBITDA are not intended to represent and should not be considered more meaningful than, or an alternative to, net income (loss), cash flow or other measures of performance in accordance with generally accepted accounting principles. EBITDA and Adjusted EBITDA data are included because the Company understands that such information is used by certain investors as one measure of an issuer’s historical ability to service debt and because certain restrictive covenants in the Indenture are based on a term very similar to the Company’s Adjusted EBITDA.
