Forward-Looking Statements

Certain statements in this presentation may constitute “forward-looking information” (“forward-looking statements”) within the meaning of applicable Canadian securities laws. Forward-looking statements are often, but not always, identified by the use of words such as “anticipate”, “estimate”, “potential”, “could”, “ongoing”, “prospective”, “expected” and similar words suggesting future outcomes. Readers are cautioned that, by their nature, forward-looking statements are based on current expectations regarding future events that involve a number of assumptions, known and unknown risks, and uncertainties. Actual results, performance or achievements of the Company, or the industry, may vary materially from what is expressed or implied by such forward-looking statements. Therefore, readers should not place undue reliance on forward-looking statements. Readers are also cautioned that potential production rates may not be indicative of long-term performance or of ultimate recovery. The Company will update its assumptions to reflect new events or circumstances when it is required, by law, to do so. The forward-looking statements in this presentation are based on management’s current expectations and assumptions that involve a number of risks and uncertainties. These risks and uncertainties include, but are not limited to: (1) risks associated with obtaining, maintaining and the timing of receipt of regulatory approvals, permits, and licenses; (2) uncertainties related to financing of the Company’s exploration activities and continued operations through access to capital markets; (3) the risk of volatile global economic conditions; (4) continued political stability; (5) continued support from the local communities, (6) operational risks in development, exploration and production delays or changes in plans with respect to exploration or development projects or capital expenditures; (7) the uncertainty of resource estimates, geological interpretations, estimates and projections in relation to production, costs and expenses, and health, safety and environmental risks; (8) the continued ability to obtain qualified staff and equipment in a timely and cost efficient manner; (9) the risk of commodity price and foreign exchange rate fluctuations; and (10) risks associated with the implementation of new technology.

Shallow Surface Anticlines and Oil Seeps

“Oil Seeps” prospects were successfully tested

Despite primitive 1900’s technology

LG-1 & LG-2 Creating Commerciality

LG-1 well: By-passed pay; underestimated reserves

Pliocene Lisu Fm. Sands with good oil shows

Miocene overpressured: gas-condensate

Deeper Eocene was original primary objective

New Optimised Pliocene location: LG-2

Up-dip step-out (600m) to LG-1 well

Simple, low-risk exploration

Effectively an “appraisal”

Shallow drilling targets (~500m)

Favourable thickening of seismic character

Potential for “untested” new reservoir LG-1 Gas Flare

Multiple washouts in Pliocene reservoir sands Erroneous Resistivity and Density log response

Resulted in false Sw computation; consequently Net Pay was under-estimated

Previous resource calculations were too pessimistic

Resources could increase by 25% to 30%

However, a large shallow lead (1,000m) has recently been identified in the Karama area

Approximately 15 Km x 3 Km; oil and gas seep in a crestal position
