The following table provides certain financial information not derived in accordance with GAAP. We have included calculations of these non-GAAP measures and reconciliations to the most comparable GAAP financial measures.

We believe that EBITDA is a recognized supplemental measurement tool widely used by analysts and investors to help evaluate a company’s overall operating performance, its ability to incur and service debt, and its capacity for making capital expenditures. We use EBITDA, in addition to operating income and cash flows from operating activities, to assess our performance relative to our competitors and relative to our own performance in prior periods. We believe that it is important for investors to have the opportunity to evaluate us using the same measures. EBITDA is calculated as follows ($ in thousands):

Preliminary Calculation of EBITDA:

		Thirteen Weeks Ended				Fourteen Weeks Ended				Fiscal Year Ended
		February 3, 2008				February 4, 2007				February 3, 2008				February 4, 2007
Income (loss) before income taxes and cumulative effect of change in accounting principle		$	(20,049	)		$	(2,132	)		$	(17,461	)		$	12,221
Interest expense			14,491				14,139				54,163				48,767
Depreciation			9,648				10,491				40,668				40,645
Amortization			1,480				847				5,513				7,585
EBITDA			5,570				23,345				82,883				109,218
Non-cash stock compensation expense			1,036				1,647				2,779				4,972
Investigation and restatement			1,725				3,371				12,348				25,739
Asset retirements and impairment			789				457				4,732				3,902
Securities class action settlement			11,700				—				11,700				—
Non-recurring charges			1,263				24				4,853				21,287
EBITDA, as adjusted		$	22,083			$	28,844			$	119,295			$	165,118

EBITDA, and EBITDA as adjusted, do not represent funds available for our discretionary use and are not intended to represent or to be used as substitute for net income or cash flow from operations data as measured under GAAP. The Company’s definition of EBITDA as adjusted, is consistent with the definitions applied in our term loan facility. The items excluded from EBITDA, and EBITDA as adjusted, are significant components of our statement of operations and must be considered in performing a comprehensive assessment of our overall financial performance. EBITDA, and EBITDA as adjusted, and the associated year-to-year trends should not be considered in isolation. EBITDA, and EBITDA as adjusted, may differ in method of calculation from similarly titled measures used by other companies.
