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 plain 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

24

Fund Raising: Fund Raising: RationaleRationale

• Exploration activities in Kenya and Chad will require considerable investment

• The EEZ is also expected to come into the frame of exploration within a few months

• Exploration is expected to significantly increase the prospectivity and value of our assets and have a positive effect on shareholder value

25

Fund Raising PlansFund Raising Plans

• The Board and management, in conjunction with our financial and legal advisers, have carefully considered ERHC’s available options and formulated a funding strategy that is expected to involve the following:– Rights issuances to existing shareholders – Direct placements to new shareholders or strategic investors– Farm-outs of part of our interests in the assets to interested E&P

companies or strategic investors

26

Fund Raising: GoalsFund Raising: Goals

• ERHC is simultaneously continuing work on farm-outs– Involve selling some of the interests in our PSCs to raise money and spread

risk by reducing ERHC’s financial obligations on the work programs

• We have more exciting assets in view across Africa– Our goal: to become one of the largest holders of exploration acreage on the

continent and one of the most successful in exploiting them

• We are rapidly making the transition from a passive holder of deep offshore licenses concentrated in one area to a company with a diversified portfolio of onshore and offshore assets across many different countries
