Non-GAAP Reconciliation: Income and E.P.S. 19

Non-GAAP Reconciliation: EBITDA 20 Last 12 Months ($ in 000's) Ended 1Q09 Net Income -- As Reported 7,646 Depreciation & Amortization 2,116 Income Taxes Net of Tax Credits 536 Interest Expense 411 Interest Income (316) Less Equity Income net of Equity Distributions 738 Loss on Discontinued Ops, Disposal of PP&E, Stock Comp Exp 2,386 EBITDA 13,516

References by the Company to "Adjusted E.P.S.", and the other "Adjusted" non-GAAP measures of income or loss from continuing operations, net income, diluted E.P.S. from continuing operations, and diluted E.P.S. in this presentation constitute non-GAAP financial measures. They refer to the Company's GAAP income or loss from continuing operations, net income, diluted E.P.S. from continuing operations, and diluted E.P.S., excluding the following items $14.1 million restructuring costs incurred in the Company's second quarter of fiscal 2007. The Company believes providing non-GAAP measures which adjust for this item, which are not indicative of the results of the Company's operations, are useful tools permitting management and the board of directors to measure, monitor and evaluate the Company's operating performance and to make operating decisions. Non-GAAP Adjusted E.P.S. and the other "Adjusted" non-GAAP measures of income or loss from continuing operations, net income, diluted E.P.S. from continuing operations, and diluted E.P.S. shown above are also used by management to assist it in planning and forecasting future operations and making future operating decisions. The Company also believes these non-GAAP measures provide meaningful information to investors in terms of enhancing their understanding of the Company's core operating performance and results and allowing investors to more easily compare the Company's financial performance on an operating basis in different fiscal periods, and also correspond more closely to investors and analyst's estimates. However, these non-GAAP measures may not be directly comparable to similarly defined measures as reported by other companies. "Adjusted E.P.S.", and the other "Adjusted" non- GAAP measures of income or loss from continuing operations, net income, diluted E.P.S. from continuing operations, and diluted E.P.S. should be considered only as supplements to, and not as substitutes for or in isolation from, other measures of financial information prepared in accordance with GAAP, such as GAAP net income, GAAP net income per share, GAAP income from continuing operations, or GAAP income from continuing operations per share. References by the Company to trailing 12-month EBITDA is a non-GAAP financial measure computed as income before interest and finance charges, income taxes (net of tax credits), depreciation and amortization, equity income from minority interest (net of distributions), interest income, loss on discontinued operations, loss on disposal of PP&E, and stock compensation expense. Management believes that this EBITDA measure offers a useful tool to measure and monitor the Company's operating performance, and that this is enhanced by eliminating the 2Q07 restructuring charge which is not indicative of the results of the Company's core operations. Management believes that this measure provides meaningful information to investors by enhancing their understanding of the Company's core operating performance and results, and it is also utilized by the Company's lenders in their assessment of the Company's performance and covenant compliance. EBITDA is also used by management to assist in planning and forecasting future operations. However, EBITDA as defined by the Company may not be directly comparable to similarly defined measures as reported by other companies. This non-GAAP measures should only be considered as supplements to, and not as substitutes for or in isolation from, other measures of financial information 21 Non GAAP Measures
