Special Meeting of Shareholders Management Presentation

• Strategy overview• Technical presentation on exploration work

programs in Kenya, Chad• Fund raising plan• Value proposition• Q & A

Our Purpose Today

• Ask our existing shareholders to contribute to ERHC’s growth and therefore realizable shareholder value

• Need to raise up to $45MM • Money will enable exploration in Kenya and Chad• Exploration will increase value of our assets and

enhance shareholder value

Brief History

• Through 2009– Primary focus on deepwater JDZ assets– Unexpected results from drilling in the JDZ

• 2010 – Awarded two Blocks in Sao Tome & Principe EEZ• 2011 – Awarded three Blocks in Republic of Chad• 2012 – Awarded Kenya Block 11A

Diversification Strategy

• Transition from single-asset model to multi-asset model– Onshore assets complement more complex and

demanding deepwater assets– More assets means more opportunities to win

• Continuing to leverage home field advantage in Africa

Kenya Exploration

Kenya Block 11A

• Located in NW Kenya adjacent to border with South Sudan

• Structural setting in the vicinity of intersection between Cretaceous and Tertiary Rift systems

• Significant production already in place in the Cretaceous basins of South Sudan and recent discoveries in the Tertiary rifts in Uganda and Kenya

Block 11A

Block 11A licensing history:

First demarcated as the larger block 10 and licensed to AMOCO in 1985. Block covered the whole of northwestern Kenya

Amoco relinquished parts of the block after ground gravity and reconnaissance seismic (~250km)

Block re-gazetted and licensed to CAMEC (Central Africa Mineral Exploration company)

CAMEC’s term expired after acquiring aero gravity and magnetic data

Similar to Uganda FindsOperator Tullow estimates the discoveries may be similar in size to the Lake Albert Rift Basin in Uganda, which are estimated at 2,000 MMBOE

Regional GeologyThe area is dominated by the Cretaceous Central Africa Rift System (CARS) and the Tertiary East Africa Rift System (EARS) with the associated basin depositional trends

Northwest KenyaThe proximity and in-trend relationship between the Lotikipi plane and the Abu Gabra Rift basins of southern Sudan suggest high oil and gas prospectivity

Recent Exploration Success• Eliye Springs well is in the adjacent Block 10BA • Loperot and Ngamia-1 wells in Block 10BB are

also nearby

Regional GeologyGravity data enabled the delineation of a sedimentary basin within the Block 11A area below the Lotikipi plain with a basin-fill believed to be in excess of 5,000 meters

Potential Reservoirs• Data acquired by Amoco in in the 1980s • Data quality is poor due to existence of

surface and subsurface volcanics, a major challenge in acquisition and processing

• Indications of existence of sedimentary rocks below the volcanics can be interpreted from seismic

On outcrop, the potential reservoir sands are composed of good-quality basement-derived units, measuring approximately 500m in thickness with measured porosities of up to 25%
