Attractive Well Economics

Note: Reserves and Economic metrics are “Unrisked”.

Oil price assumptions, $/Bbl - $91.72 in 2013, $89.88 in 2014, $95.00 thereafter. NGL price assumptions, $/Bbl - $42.77 in 2013, $41.91 in 2014, $44.30 thereafter.

Gas price assumptions, $/MMBtu - $3.71 in 2013, $4.10 in 2014, $4.60 thereafter.

		HIGHLIGHTS
Reeves County	Vertical Wolfbone	• 40-acre development; 145 MMBoe net risked resources; ~1,300 gross locations • Down-spacing potential
	Horizontal Wolfcamp	• Early stage - operators testing upper and middle Wolfcamp • Completed 4 horizontals in acquired area
	Avalon / Bone Spring	• Additional horizontal upside potential
	Other Formations	• May ultimately recognize upside in deeper, gas-prone formations • Likely requires higher gas price environment
Gaines County Exploration Play		• Exploration play; no wells drilled to date • Wolfcamp is a likely target
