(a)	For the year ended December 31, 2008, the Company recognized a non-cash ceiling test write-down of its oil and gas properties totaling $485.5 million. As a result, earnings in 2008 were insufficient to cover fixed charges by $485.4 million, and therefore no ratio is shown.
(b)	Fixed charges include interest expense on indebtedness and capitalized interest in addition to the amortization of debt issuance costs, discounts and premiums.
