(1)

The company makes use of financial measures that are not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”) to help in the

assessment of ongoing operating performance. These non-GAAP financial measures are reconciled to their most directly comparable GAAP measures in the tables

above. We define Adjusted EBITDA as net income plus net interest expense, income tax expense and depreciation, depletion, amortization and impairment expense.

We present Adjusted EBITDA because we believe it provides 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 is not defined by GAAP and, as such, should not be construed as an

alternative to net income (loss) or operating cash flow. We define margin as revenues less direct operating costs.

We present margin because we believe it to be the

component of our earnings most impacted by the variability in our contract drilling and pressure pumping operations. Margin is not defined by GAAP and, as such,

should not be construed as an alternative to net income (loss).
