Unaudited Pro forma Condensed Consolidated Statements of Operations
and Balance Sheet to Reflect Sale of Barnett Shale Assets

The following unaudited pro forma condensed consolidated balance sheet and statements of operations give effect to the following transactions:

May 2009 Sale of 60% of Denbury’s Barnett Shale Natural Gas Assets. In May 2009, Denbury Resources Inc. (“Denbury”) entered into an agreement to sell 60% of its Barnett Shale natural gas assets to Talon Oil and Gas LLC (“Talon”), a privately held company, for $270 million (before closing adjustments). The effective date under the agreement was June 1, 2009, and consequently operating net revenues after June 1, net of capital expenditures, along with any other purchase price adjustments, were adjustments to the selling price. In June 2009, Denbury completed approximately three-quarters of the sale and closed the remaining portion of the sale in July 2009. Net proceeds of the sale were $259.8 million (after closing adjustments and net of $8.1 million paid on natural gas swaps transferred in the sale). Denbury used the net proceeds from the sale to repay bank debt. Denbury did not record a gain or loss on the sale in accordance with the full cost method of accounting.

December 2009 Sale of Remaining 40% of our Barnett Shale Natural Gas Assets. In December 2009, Denbury closed the sale of its remaining 40% interest in Barnett Shale natural gas assets to Talon for $210 million (before closing adjustments). The effective date under the agreement was December 1, 2009. The proceeds of this sale were used to reduce outstanding bank debt. Denbury does not expect to record a gain or loss on the sale in accordance with the full cost method of accounting. Further, the sale was structured as a deferred like-kind exchange in conjunction with its December 2009 purchase of Conroe Field in order to defer most of the tax impacts of the sale.

The unaudited pro forma condensed consolidated balance sheet which follows gives effect to the sale of 40% of Denbury’s Barnett Shale natural gas assets as if the sale occurred on September 30, 2009. The effect of the May 2009 sale of 60% of its Barnett Shale natural gas assets is included in its historical condensed consolidated balance sheet as of September 30, 2009 as the sale occurred prior to September 30, 2009.

The unaudited pro forma condensed consolidated statements of operations which follow include the effect of the sale of 60%, and subsequent sale of 40%, of Denbury’s Barnett Shale natural gas assets as if each sale occurred on January 1, 2008.

	(a)		Represents the increase in cash of $190 million, reduction in debt of $20 million and reduction in oil and natural gas properties of $210 million resulting from the sale of the remaining 40% of Denbury’s Barnett Shale natural gas assets. The Company’s bank debt outstanding as of September 30, 2009 was $20 million. As such, the pro forma adjustment reflects the pay down of $20 million of bank debt. The Company incurred additional debt in December 2009 and utilized the $210 million in proceeds to pay down bank debt in December 2009.

	(b)		Represents the decrease in revenues from the sale of oil and natural gas resulting from the disposal of Denbury’s Barnett Shale natural gas assets.

	(c)		Represents the reduction in lease operating expense, production expenses and depletion attributable to the disposal of Denbury’s Barnett Shale natural gas assets. Denbury’s estimated pro forma oil and natural gas depletion rate was $13.16 per BOE for the nine months ended September 30, 2009 and $12.03 per BOE for the year ended December 31, 2008. Denbury’s historical oil and natural gas depletion rate is $11.44 for the nine months ended September 30, 2009 and $11.55 for the year ended December 31, 2008.

	(d)		Denbury utilized the proceeds from the sale of 60% of its interest in its Barnett Shale natural gas assets to repay a portion of its credit facility. The adjustment to interest expense reflects the reduction in interest expense as if the repayment occurred on January 1, 2008. Denbury used the proceeds from the sale of the remaining 40% of its interest in its Barnett Shale natural gas assets to reduce outstanding bank debt.

	(e)		Represents the income tax effect of the pro forma adjustments at Denbury’s approximate statutory tax rate of 38%.
