Non-GAAP Financial Measures 15 Non-GAAP Financial Measures Included in this presentation are certain non-GAAP financial measures designed to complement the financial information presented in accordance with generally accepted accounting principles in the United States of America because management believes such measures are useful to investors. Adjusted gross margin Adjusted gross margin represents net sales less cost of sales excluding adjustments which are outlined in the quantitative reconciliation provided earlier in this presentation. Management uses Adjusted gross margin to facilitate our analysis and understanding of our business operations and believes that Adjusted gross margin is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company. Adjusted gross margin should not be considered as an alternative to gross margin or any other performance measure derived in accordance with GAAP. Adjusted selling, general and administrative expenses Adjusted selling, general and administrative expenses represents selling, general and administrative expenses excluding adjustments which are outlined in the quantitative reconciliation provided earlier in this presentation. Management uses Adjusted selling, general and administrative expenses to facilitate our analysis and understanding of our business operations and believes that Adjusted selling, general and administrative expenses is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company. Adjusted selling, general and administrative expenses should not be considered as an alternative to selling, general and administrative expenses or any other performance measure derived in accordance with GAAP. Adjusted operating income Adjusted operating income represents operating income (loss), excluding adjustments which are outlined in the quantitative reconciliation provided earlier in this presentation. Management uses Adjusted operating income to facilitate our analysis and understanding of our business operations and believes that Adjusted operating income is useful to investors because it provides a supplemental way to understand the underlying operating performance of the Company. Adjusted operating income should not be considered as an alternative to operating income or any other performance measure derived in accordance with GAAP. 15

Non-GAAP Financial Measures Continued 16 Adjusted net income (loss) and Adjusted EPS Adjusted net income and Adjusted EPS represent net income (loss) and EPS, excluding adjustments which are more specifically outlined in the quantitative reconciliation provided earlier in this presentation. Management uses Adjusted net income and Adjusted EPS to evaluate the Company's operating performance and believes that Adjusted net income and Adjusted EPS are useful to investors because they provide a supplemental way to possibly better understand the underlying operating performance of the Company. Adjusted net income and Adjusted EPS should not be considered as alternatives to net income, operating income or any other performance measures derived in accordance with GAAP. Adjusted EBITDA Adjusted EBITDA represents net loss before income tax expense (benefit), interest expense, net, and depreciation and amortization expense, adjusted to exclude the following: restructuring charges, write down of long-lived assets, ERP integration costs, plant start-up costs, stock-based compensation expense (recovery), goodwill impairment, acquisition related fees, net curtailment and settlement gain (loss) on benefit plans, net foreign exchange (gain) loss, and net (gain) loss on sales and disposals of assets. We present Adjusted EBITDA as a supplemental measure of our performance and ability to service debt. We also present Adjusted EBITDA because we believe such measure is frequently used by securities analysts, investors and other interested parties in the evaluation of companies in our industry. We believe Adjusted EBITDA is an appropriate supplemental measure of debt service capacity, because cash expenditures on interest are, by definition, available to pay interest, and tax expense is inversely correlated to interest expense because tax expense goes down as deductible interest expense goes up; depreciation and amortization are non-cash charges. The other items excluded from Adjusted EBITDA are excluded in order to better reflect our continuing operations. In evaluating Adjusted EBITDA, you should be aware that in the future we may incur expenses similar to the adjustments in this presentation. Our presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by these types of adjustments. Adjusted EBITDA is not a measurement of our financial performance under GAAP and should not be considered as an alternative to net income, operating income or any other performance measures derived in accordance with GAAP or as an alternative to cash flow from operating activities as a measure of our liquidity. 16

Non-GAAP Financial Measures Continued 17 Our Adjusted EBITDA measure has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP. Some of these limitations are: it does not reflect our cash expenditures, future requirements for capital expenditures or contractual commitments; it does not reflect changes in, or cash requirements for, our working capital needs; it does not reflect the significant interest expense or the cash requirements necessary to service interest or principal payment on our debt; although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and our Adjusted EBITDA measure does not reflect any cash requirements for such replacements; it is not adjusted for all non-cash income or expense items that are reflected in our statements of cash flows; it does not reflect the impact of earnings or charges resulting from matters we consider not to be indicative of our ongoing operations; it does not reflect limitations on or costs related to transferring earnings from our subsidiaries to us; and other companies in our industry may calculate this measure differently than we do, limiting its usefulness as a comparative measure. Because of these limitations, Adjusted EBITDA should not be considered as a measure of discretionary cash available to us to invest in the growth of our business or as a measure of cash that will be available to us to meet our obligations. You should compensate for these limitations by relying primarily on our GAAP results and using Adjusted EBITDA only supplementally. 17
