             EXPLANATION OF EBITDA, FREE CASH FLOW AND NET DEBT


      .     EBITDA represents earnings before interest expense,
            income taxes, depreciation and amortization

      .     Free Cash Flow represents Net Cash from Operations
            less Capital Expenditures and Working Capital

      .     Net Debt represents debt minus cash and cash equivalents

      .     Management believes that EBITDA and Free Cash Flow are
            useful to investors as a measure of operating performance
            and liquidity

      .     Management believes that Net Debt is useful to investors
            as a measure of financial position

      .     EBITDA, Free Cash Flow and Net Debt should not be considered
            alternatives to (i) net income (loss) (determined in
            accordance with GAAP), (ii) cash flows (determined in
            accordance with GAAP), or (iii) liquidity
