As more fully discussed in Note 6 to the Consolidated Financial Statements included in EOG's 2010 Annual Report, EOG maintains various stock-based compensation plans. Stock-based compensation expense is included in the Consolidated Statements of Income based upon the job function of the employee receiving the grants as follows (in millions):

		Three Months Ended				Six Months Ended
		June 30,				June 30,
		2011		2010		2011		2010

Lease and Well	$	7.2	$	6.0	$	14.9	$	12.3
Gathering and Processing Costs		0.2		0.3		0.4		0.3
Exploration Costs		5.5		5.3		11.6		10.8

The EOG Resources, Inc. 2008 Omnibus Equity Compensation Plan, as amended (2008 Plan), provides for grants of stock options, stock-settled stock appreciation rights (SARs), restricted stock, restricted stock units and other stock-based awards. At June 30, 2011, approximately 6.8 million common shares remained available for grant under the 2008 Plan. EOG's policy is to issue shares related to the 2008 Plan from previously authorized unissued shares.

Stock Options and Stock-Settled Stock Appreciation Rights and Employee Stock Purchase Plan. The fair value of all Employee Stock Purchase Plan (ESPP) grants is estimated using the Black-Scholes-Merton model. The fair value of stock option and SAR grants is estimated using the Hull-White II binomial option pricing model. Stock-based compensation expense related to stock option, SAR and ESPP grants totaled $10.5 million and $9.3 million during the three months ended June 30, 2011 and 2010, respectively, and $19.9 million and $17.8 million during the six months ended June 30, 2011 and 2010, respectively.

Weighted average fair values and valuation assumptions used to value stock option, SAR and ESPP grants during the six-month periods ended June 30, 2011 and 2010 are as follows:

		Stock Options/SARs				ESPP
		Six Months Ended				Six Months Ended
		June 30,				June 30,
		2011		2010		2011		2010

Weighted Average Fair Value of Grants	$	36.57	$	33.38	$	21.55	$	24.66
Expected Volatility		37.13%		38.05%		30.26%		34.78%
Risk-Free Interest Rate		1.12%		1.21%		0.18%		0.15%
Dividend Yield		0.6%		0.6%		0.6%		0.7%
Expected Life		5.4 yrs		5.0 yrs		0.5 yrs		0.5 yrs

Expected volatility is based on an equal weighting of historical volatility and implied volatility from traded options in EOG's common stock. The risk-free interest rate is based upon United States Treasury yields in effect at the time of grant. The expected life is based upon historical experience and contractual terms of stock option, SAR and ESPP grants.
