We plan on directing 90% of our $490 million capital expenditure budget to the drill bit in 2011.”

Operational and Financial Update

Average daily production for the fourth quarter of 2010 was 7,511 Boe per day (99% was produced from Williston Basin properties), an increase of 144% as compared to 3,073 Boe per day in the fourth quarter of 2009. Sequential quarter-over-quarter production growth was 2,004 Boe per day, or 36%. In the fourth quarter of 2010, 95% of the production was from oil. Average daily production for the full year 2010 was 5,206 Boe per day compared to 1,950 Boe per day for 2009. Average daily production by project area is listed in the following table:

		Average daily production (Boepd)
		for the years ended								for the quarters ended
		December 31,								December 31,
		2010				2009				2010				2009
Williston Basin:
West Williston			2,070				999				3,365				1,106
East Nesson			1,643				508				2,295				1,016
Sanish			1,419				366				1,774				792
Total Williston Basin			5,132				1,873				7,435				2,914
Other			74				77				76				159
Total			5,206				1,950				7,511				3,073

Average price per barrel of oil, without realized derivatives, was $73.05in the fourth quarter of 2010compared to $65.09 in the fourth quarter of 2009 and $69.60 for the full year 2010 compared to $55.32 for the full year 2009. The average price differential compared to West Texas Intermediate crude oil index prices was 14% in the fourth quarter 2010compared to 14% in the fourth quarter of 2009 and 13% for the full year 2010 compared to 17% for the full year 2009.

Total revenue for the fourth quarter of 2010 was $49.1 million compared to $17.5 million for the fourth quarter of 2009, an increase of 181%. Sequential quarter-over-quarter revenue growth was $16.2 million, or 49%. Total revenue for the full year 2010 was $128.9 million compared to $37.8 million in 2009.

Lease operating expenses for the fourth quarter of 2010 totaled $5.5 million, or $7.92 per Boe, an 18% decrease per Boe over the fourth quarter of 2009 of $9.60 per Boe. Lease operating expenses for the full year 2010 totaled $14.6 million, or $7.67 per Boe, a 37% decrease per Boe over the full year 2009 of $12.21 per Boe. This year-over-year decrease was due primarily to increases in oil production volume as well as a higher proportion of production sourced from Bakken wells, which have a lower operating cost than the traditional Madison wells.

Production taxes for the fourth quarter of 2010 totaled $5.6 million, or 11.5% of revenue, and for the full year 2010 totaled $13.8 million, or 10.7% of revenue. Production taxes were higher in 2010 compared to 2009, which were 10.1% of revenue, primarily due to a higher proportion of production sourced from North Dakota, which imposes a production tax rate that is higher than other areas of operations at 11.5%.

Depreciation, depletion and amortization for the fourth quarter of 2010 totaled $13.4 million, or $19.46 per Boe, compared to $6.5 million, or $23.10 per Boe, in the fourth quarter of 2009. Depreciation, depletion and amortization for the full year 2010 totaled $37.8 million, or $19.91 per Boe, compared to $16.7 million, or $23.42 per Boe, for the full year 2009.

The Company recorded a non-cash charge related to impairment of oil and gas properties of $12.0 million for the full year 2010 related to unproved property leases that expired during the year.

General and administrative expenses for the fourth quarter of 2010 totaled $7.6 million, or $11.05 per Boe, compared to $5.1 million, or $17.89 per Boe, in the fourth quarter of 2009. General and administrative expenses for the full year 2010 increased to $19.7 million, or $10.39 per Boe, from $9.3 million, or $13.12 per Boe, for the full year 2009. Of this increase, approximately $4.2 million was due to higher advisory, audit, legal, tax, and filing fees primarily related to the IPO and additional costs of being a public entity. In addition, the Company had a non-cash expense of $1.2 million related to the amortization of restricted stock awards granted during 2010, which was the first year the Company had issued restricted stock. The remaining increase was primarily due to higher costs related to employee compensation (including bonuses paid during the first quarter of 2010 and accrued bonuses to be paid in the first quarter of 2011) and contract labor. As of December 31, 2010, Oasis had 62 full-time employees compared to 27 full-time employees as of December 31, 2009.

In March 2010, the Company recorded a $5.2 million stock-based compensation charge associated with Oasis Petroleum Management LLC (“OPM”) granting 1.0 million C Units to certain of our employees. During the fourth quarter of 2010, Oasis recorded an additional $3.5 million in stock-based compensation expense primarily associated with OPM granting discretionary shares of our common stock to certain of our employees who were not C-Unit holders and certain contractors. The combined $8.7 million of stock-based compensation charges were non-cash and non-dilutive to Oasis shareholders.

Prior to its corporate reorganization, the Company was a limited liability company not subject to entity-level income tax. Accordingly, no provision for federal or state corporate income taxes was recorded for the year ended December 31, 2009 as taxable income was allocated directly to its equity holders. In connection with the closing of the IPO, the Company merged into a corporation and became subject to federal and state entity-level taxation. In connection with this corporate reorganization, an initial net deferred tax liability of $29.2 million was established for differences between the tax and book basis of assets and liabilities and a corresponding deferred tax expense was recorded in the Consolidated Statement of Operations. Oasis recorded additional deferred income tax expenses of $6.2 million and $0.2 million in September 2010 and December 2010, respectively, for discrete adjustments related to changes in estimates to the initial deferred tax liability recorded in June 2010. Subsequent to its corporate reorganization, Oasis recorded federal and state income tax expense of $7.4 million on pre-tax income earned in the post-reorganization period from June 17, 2010 (the effective date of the reorganization) to December 31, 2010.

Adjusted EBITDA for the fourth quarter of 2010 was $31.2 million, an increase of $22.2 million, or 247%, over the fourth quarter of 2009 of $9.0 million. Adjusted EBITDA for the full year 2010 was $82.2 million, an increase of $65.5 million, or 392%, over the full year 2009 of $16.7 million.

The Company reported net income of $1.6 million in the fourth quarter of 2010 compared to a net loss of $3.6 million in the fourth quarter of 2009. For the full year 2010, Oasis reported a net loss of $29.7 million, or $0.61 per weighted average diluted share. The third and fourth quarter of 2010 included non-cash increases of $6.2 million and $0.2 million, respectively, to the Company’s estimated deferred tax liability above the initial book and tax differences of $29.2 million recorded at the time of the IPO. The full year 2010 also included a non-cash charge related to the impairment of oil and gas properties of $12.0 million related to unproved property leases that expired during the year.

Capital Expenditures and Liquidity

Oasis’ capital expenditures were $162.3 million for the fourth quarter of 2010 and $345.6 million for the full year 2010. The Company’s capital expenditures for drilling, development, acquisition and undeveloped acreage costs for the four quarters and full year of 2010 are summarized in the following table:

($ in millions)																		Full Year
Project Area		1Q 10				2Q 10				3Q 10				4Q 10				2010
West Williston		$	11.5			$	39.7			$	46.2			$	143.4			$	240.8

Total (1)		$	36.9			$	71.6			$	74.8			$	162.3			$	345.6

On December 31, 2010, Oasis had total cash and cash equivalents of $143.5 million and had no outstanding indebtedness under its $120 million borrowing base. On February 2, 2011, the Company issued $400 million of 7.25% senior unsecured notes (the “Notes”). The Notes resulted in net proceeds to the Company of approximately $390 million and will mature on February 1, 2019. After giving effect to the issuance of these Notes, the Company had $533.5 million of cash and $137.5 million available under its revolving credit facility, which was redetermined and adjusted in association with the Notes issuance.

Reserves

The following is a summary of Oasis’ changes in quantities of proved oil and gas reserves for the year ended December 31, 2010:

		Oil (MBbl)				Gas (MMcf)				Total (MBoe)
Balance — December 31, 2009			12,421				5,270				13,299
Revisions of previous estimates			2,235				1,897				2,552
Extensions, discoveries and other additions			22,445				12,172				24,473
Sales of reserves in place			(122	)			(5	)			(123	)
Purchases of reserves in place			1,363				696				1,479
Production			(1,792	)			(651	)			(1,900	)
Balance — December 31, 2010			36,550				19,379				39,780
Proved developed reserves, December 31, 2010			15,650				8,208				17,018
Proved undeveloped reserves, December 31, 2010			20,900				11,171				22,762

In 2010, the Company had a total of 24,473 MBoe of additions. An estimated 8,122 MBoe of extensions and discoveries were associated with new wells, which were producing at December 31, 2010, with approximately 99%

of these reserves from wells producing in the Bakken or Three Forks formations. An additional 16,351 MBoe of proved undeveloped reserves were added across all three of the Company’s Williston Basin project areas associated with the Company’s 2010 operated and non-operated drilling program, with 100% of these proved undeveloped reserves in the Bakken or Three Forks formations.

Additionally, Oasis had net positive revisions of 2,552 MBoe in 2010. Approximately 29% of these revisions were due to the increase in oil prices from 2009 to 2010. An estimated 29% of the increase was due to higher working interests in proved wells. The remaining 42% of these revisions were due to other changes, including the estimate of recoverable hydrocarbons from proved wells.

Recent Developments

Based on inclement winter weather experienced in the Williston Basin, Oasis currently believes that its first and second quarters of 2011 production will be around the low-end of its previously announced guidance ranges of 8,000 to 9,200 Boepd and 9,800 to 11,200 Boepd, respectively. Accordingly, the Company had 18 gross operated wells waiting on completion as of March 1, 2011. Oasis is currently running six operated rigs in the Williston Basin, with five wells drilling in West Williston and one well drilling in East Nesson, and expects to add a seventh operated rig before the end of the first quarter of 2011.

Non-GAAP Financial Measures

Adjusted EBITDA is a supplemental non-GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDA as earnings before interest expense, income taxes, depreciation, depletion and amortization, property impairments, exploration expenses, unrealized derivative gains and losses and non-cash stock-based compensation expense. Adjusted EBITDA is not a measure of net income or cash flows as determined by United States generally accepted accounting principles, or GAAP.

The following tables present a reconciliation of the non-GAAP financial measure of Adjusted EBITDA to the GAAP financial measures of net loss and net cash provided by operating activities, respectively.
