(1) Adjusted EBITDA is a supplemental financial measure not defined by United States generally accepted accounting principles, or U.S. GAAP. We define Adjusted EBITDA as net income (loss) plus net interest

expense, income tax expense (benefit) and depreciation, depletion, amortization and impairment expense (including impairment of goodwill). We present Adjusted EBITDA because we believe it provides to both

management and investors additional information with respect to both the performance of our fundamental business activities and our ability to meet our capital expenditures and working capital requirements.

Adjusted EBITDA should not be construed as an alternative to the U.S. GAAP measure of net income (loss).
