Strategy

Identify, acquire and appraise material upstream oil and gas exploration opportunities:

Utilising network of global contacts Primarily unconventional hydrocarbons, CBM, Shale Gas, Shale Oil. Low cost of entry, with primary expenditure on the drill bit High materiality (> 1 TCF Gas, or >10 Million bbl Oil) Projects where Challenger will act as operator

Evaluate and high grade exploration projects to ensure efficient expenditure of shareholders funds Implement staged and cost effect exploration and appraisal programs to evaluate projects with an eye on the best development or exit strategy

Proven Shales

Barnett Shale First recognised shale gas project in US with more than 14,000 wells now drilled Wells in core area recovering ~ 3 BCF Producing 1.8 TCF/yr Woodford Shale More recently developed Wells in core area recovering ~ 4 BCF Over 1,000 wells drilled Producing 240 BCF/yr

Much lower risk than shale plays in frontier areas.

Ellenburger Hybrid (Sand/Unconventional)

Well

First appraisal well successfully drilled Dec/Jan 2011. Strong gas shows whilst drilling over a number of zones. A total of 2,300 ft of gas charged zones were intersected

13

Ellenburger

Fracture and high porosity zone

Drilling results confirmed a significant gas charged structure ­ potentially multi TCF gas in place Fractures and high porosity intersected at the top of the Ellenburger, however zone cemented during setting of casing, which likely limited gas production Upper zone at the top of formation is the initial target for horizontal well Original Gas in Place (OGIP) 1.6 TCF

14

Triple Crown ­ Canyon Hybrid Play

Very strong gas shows over an 1150 ft Sand Challenger believe this to be a hybrid play that consists of a number of sands interbedded within a large unconventional gas zone Sand 1,150 FT Gas Column Strong Gas Shows Unconventional Zone with interbedded sand stringers 2.5 - 10%

Preliminary analysis suggests this play has a very large gas in place, with analysis of known wells suggesting Original Gas in place (OGIP) equivalent to 7.4 TCF over existing acreage

As expected by the depositional environment, analysis of logs of previously drilled wells in the area suggest the potential for this play improves moving down dip off structure Sand/Siltstone

Karoo Basin ­ International gas focus

Shale Gas within the Karoo Basin is now a major focus for international E&P companies seeking to put their foot on new resources Following initial 12 month Technical Co-Operation permits, both Shell and Falcon have moved to the next step of formally applying for Exploration Permits Challenger permit of ~ 800,000 acres centred on only well (CR 1/68) within the basin to flow significant gas to surface Very well positioned having already reached agreement with Black Empowerment Partners (BEE), and first company to submit its application EMP submitted in September 2010 ­ awaiting approval. Currently a fraccing moratorium in place until March 2012.

US Energy Information Administration Report on Shale gas potential around the world identified the following:

Karoo Basin large potential "Risked Recoverable Resource" averaged across basin ~ 6.8 BCF / square mile. Equivalent to more than 7 TCF of Risked Recoverable Resource within Challengers Application Area

Summary

Challenger Energy's strategy is to identify, acquire and appraise material upstream oil and gas exploration opportunities Mercury Stetson Prospect in North Texas, US

Two proven shale formations ­ Barnett and Woodford Massive potential gas in place with OGIP estimated at 360 BCF/sq mile Large prospect area ­ potentially up to 55,000 acres (86 sq miles) Prospect is close to existing infrastructure Contiguous land position of ~ 26,000 acres with a short term target of 35,000 acres.

Triple Crown Prospect in Texas, US

Significant acreage ­ 45,000 acres with options over a further 6,500 acres. Large gas charged zones, Ellenburger (dolomite) and an unconventional Hybrid play which is geologically analogous to Montney Hybrid Play in Western Canada with an estimated OGIP of 9 TCF. Testing to commence shortly on both the Ellenburger and Hyprid Play

Karoo Basin in South Africa

Shale gas in Karoo Basin now a major focus for international E&P companies (eg Shell, Cheasapeake, Statoil and Sasol) Challenger Energy's permit of approx. 800,000 acres centred on only well within basin to flow significant gas to surface to date, awaiting approval. Independent US Energy Information Agency report suggests Risked Recoverable Resource of more than 7 TCF in application area.

Attractive assets have exciting potential to grow significant shareholder value

Risks

Based on analog data and comparison of shale properties to existing plays Dependent on well spacing Further seismic required to fully define prospect area. Dependent on well type and frac stages, based on equivalent areas, vertical may be an effective option in this area. Based on equivalent areas Drilling through the Oauchita Thrust may increase Costs Based on 80 acre spacing

Joint Venture Agreement

Governs relationship between the parties until no leases held by any party. Provides for Challenger to earn 50% interest in Phase 1, by the following:

Payment of up to $2.2 million as and when required for the renewal and extension of existing leases plus the acquisition of additional leases Drill, fracture stimulate, complete and test TWO vertical wells. The parties anticipate that the first well will incorporated the re-entry and completion of the existing well on the property, however in the event that is unsuccessful, a new well will be drilled and the value of the seismic program adjusted to keep Challenger whole. Conduct a seismic program funded partially by revenue from first well to fully define the extend of the shales in the prospect area Connect the two wells to the nearby sales pipeline Challenger is required to pay the balance of the $2.2 M if it does not drill and complete the first well.

Phase 2

Subject to the terms of the agreement, provides for the parties to enter into a Phase 2 program including two horizontal wells in each of the Barnett and Woodford shales. Parties to fund their share, or in the absence of all parties agreeing to fund their share, a mechanism exists for the funding parties to earn additional interest
