*Discussion of Non-GAAP Measures The non-GAAP financial measures used in this release are utilized by management in comparing our operating performance on a consistent basis.  We believe that these financial measures are appropriate to enhance the overall understanding of our underlying operating performance trends compared to historical and prospective periods and our peers. We believe that these measures provide important supplemental information to management and investors regarding financial and business trends relating to the Company's financial condition and results of operations as well as insight into the compliance with our debt covenants.  Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information calculated in accordance with GAAP.  Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measures.  A reconciliation of non-GAAP financial measures presented above to our GAAP results has been provided in the financial tables included in this press release. Organic Sales Growth Organic sales growth in this release excludes the impact of foreign currency translation. Non-GAAP Net Income, Non-GAAP Diluted Earnings Per Share and Non-GAAP Diluted EPS Guidance  Non-GAAP Net Income, Non-GAAP Diluted Earnings Per Share and Non-GAAP Diluted Earnings Per Share Guidance exclude acquisition related amortization expense, impairment of goodwill and intangible assets, acquisition related stock compensation expense, restructuring costs, non-cash amortization of interest rate swap expense and other income or charges that management does not consider to be directly related to the Company’s core operating performance.  Non-GAAP Diluted Earnings Per Share is calculated by dividing Non-GAAP Net Income by GAAP weighted average shares outstanding (diluted).  Non-GAAP Income From Operations and Non-GAAP Operating Income Margin Non-GAAP Income From Operations is calculated by excluding acquisition related amortization expense, impairment of goodwill and intangible assets, acquisition related stock compensation expense and restructuring costs.  Non-GAAP Operating Income Margin is calculated by dividing Non-GAAP Income From Operations by GAAP Net Sales. Non-GAAP Adjusted EBITDA and Non-GAAP Adjusted EBITDA Guidance Non-GAAP Adjusted EBITDA and Non-GAAP Adjusted EBITDA Guidance represent earnings before interest, taxes, depreciation, acquisition related amortization, restructuring costs, stock-based compensation, asset impairment and other income or charges that management does not consider to be directly related to the Company’s core operating performance.  Non-GAAP Adjusted EBITDA Margin Non-GAAP Adjusted EBITDA margin is calculated by dividing Non-GAAP Adjusted EBITDA by GAAP Net Sales. Non-GAAP Free Cash Flow and Non-GAAP Free Cash Flow Guidance Non-GAAP Free Cash Flow and Non-GAAP Free Cash Flow Guidance is calculated by deducting purchases of property, plant and equipment from net cash flows from operating activities. Non-GAAP Operating Working Capital Non-GAAP Operating Working Capital is calculated by deducting accounts payable from net trade receivables plus inventories. Net Debt Net Debt is calculated by subtracting cash from total debt. 13
