Business Plan - 2013

§FOCUS + DELEVER + GROW

§ReFOCUS Portfolio and CAPEX on Highest Returning Basins

§Currently: Williston, Eagle Ford, PRB, Permian

§DELEVER: Actively Pursue Divestitures

§Properties trading above internal assessment of fair value

§Lack of scale/high margin production

§Exemplified by recent transactions for ~$22mm

§Reduce leverage and maintain that profile

§Target Debt/EBITDA < 2.0x by YE13 (1)

§GROW:The Outcome of Sound Investment Decisions

§Bakken/TFS:

§Accelerate with company owned drilling rig

§Eagle Ford:

§Mobilize rig to commence continuous drilling program

(1)Excluding building mortgage and rig loan which are secured by the building and rig, respectively.EBITDA definition per bank loan agreement (excludes Rig EBITDA)

Low Risk Development

Focus On Four Core Positions in Premier Oil Resource Plays Predominately HBP

§Williston: 23,000+ net acres; Bakken, Three Forks

§Eagle Ford: 7,300+ net acres: Eagle Ford, Buda

§PRB: 17,000+ net acres; stacked potential

§Permian: 40,000+ net acres: conventional & stacked pay opportunities

Premier Positions in Emerging Oil Resource Plays

§Permian: 40,000+ net acres; exposure to numerous emerging plays

§Canada: 40,000+ net acres Duvernay/Pekisko

Low Risk Conventional Development

§Williston Basin: Red River/Duperow

§PermianBasin: Spires Ranch - hz Strawn

§Permian Basin: Delaware Basin - dry gas

§Farm-out: 36 Sections; four year term

§Represents a continuous, self sourced resource contained in a
shaley organic rich low permeability reservoir

§Shale assessment and productivity expectations developed
based on a review of analogues (i.e. Eagle Ford, Kaybob,
Pembina/ Willesden Green)

§All critical shale parameters point to the Duvernay being an
excellent source and reservoir rock

§Available rock and completion data point to Canaxas lands
containing volatile oil hydrocarbons in place
