| (1) | We believe that, in addition to other financial measures, Adjusted Income Before Taxes and Adjusted EBITDA are appropriate indicators to assist in the evaluation of our operating performance on a period-to-period basis.  We also use Adjusted Income and Adjusted EBITDA internally as performance measures for planning purposes, including the preparation of annual operating budgets, and for compensation purposes, including bonuses for certain employees.  Adjusted EBITDA is also used to evaluate our ability to service debt because the excluded charges do not have an impact on our prospective debt servicing capability and these adjustments are contemplated in our credit facility for the computation of our debt covenant ratios.  However, Adjusted Income and Adjusted EBITDA should be considered as a supplement to, not a substitute for, operating income, net income or other financial performance measures prepared in accordance with U.S. generally accepted accounting principles. |
