Pursuant to the requirements of the ASX Listing Rule 5.41 and 5.43 the technical and Prospective Resources information relating to Austria and Italy contained in this presentation has been reviewed by Paul Fink as part of the due diligence process on behalf of ADX. Mr. Fink is Technical Director of ADX Energy Ltd is a qualified geophysicist with 30 years of technical, commercial and management experience in exploration for, appraisal and development of oil and gas resources. Mr. Fink is a member of the EAGE (European Association of Geoscientists & Engineers) and FIDIC (Federation of Consulting Engineers). ADX confirms that it is not aware of any new information or data that may materially affect the information included in the relevant market announcements for reserves or resources and that all material assumptions and technical parameters underpinning the estimates in the relevant market announcements continue to apply and have not materially changed. Independent audit of developed reserves have been completed for ADX’ Zistersdorf and Gaiselberg fields (“Fields”) in the Vienna basin and Anshof in Upper Austria (Austria) by RISC Advisory Pty Ltd (“RISC”). RISC conducted an independent audit of ADX’ Fields evaluations, including production forecasts, cost estimates and project economics. Production from existing wells is classified as Developed Producing. Production from planned recompletion of existing wells to new intervals is classified as Developed Non-Producing. RISC is an independent advisory firm offering the highest level of technical and commercial advice to a broad range of clients in the energy industries worldwide. RISC has offices in London, Perth, Brisbane and South-East Asia and has completed assignments in more than 90 countries for over 500 clients and has grown to become an international energy advisor of choice. PRMS RESERVES CLASSIFICATIONS USED IN THIS PRESENTATION: Developed Reserves are quantities expected to be recovered from existing wells and facilities. Developed Producing Reserves are expected to be recovered from completion intervals that are open and producing at the time of the estimate. Developed Non-Producing Reserves include shut-in and behind-pipe reserves with minor costs to access. Undeveloped Reserves are quantities expected to be recovered through future significant investments. A. Proved Reserves (1P) are those quantities of Petroleum that by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be commercially recoverable from known reservoirs and under defined technical and commercial conditions. If deterministic methods are used, the term “reasonable certainty” is intended to express a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90% probability that the quantities actually recovered will be equal or exceed the estimate. B. Probable Reserves are those additional Reserves which analysis of geoscience and engineering data indicate are less likely to be recovered than Possible Reserves. It is equally likely that actual remaining quantities recovered will be greater than or less than the sum of the estimated Proved plus Probable Reserves (2P). In this context, when probabilistic methods are used, there should be at least a 50% probability that the actual quantities recovered will equal or exceed the 2P estimate. C. Possible Reserves are those additional Reserves that analysis of geoscience and engineering data suggest are less likely to be recoverable that Probable Reserves. The total quantities ultimately recovered from the project have a low probability to exceed the sum of Proved plus Probable plus Possible (3P) Reserves, which is equivalent to the high-estimate scenario. When probabilistic methods are used, there should be at least a 10% probability that the actual quantities recovered will equal or exceed the 3P estimate. Possible Reserves that are located outside the 2P area (not upside quantities to the 2P scenario) may exist only when the commercial and technical maturity criteria have been met (that incorporate the Possible development scope). Standalone Possible Reserves must reference a commercial 2P project. PROSPECTIVE RESOURCE CLASSIFICATIONS USED IN THIS PRESENTATION: Prospective Resources are those estimated quantities of petroleum that may potentially be recovered by the application of a future development project(s) relate to undiscovered accumulations. These estimates have both an associated risk of discovery and a risk of development. Further explorations appraisal and evaluation is required to determine the existence of a significant quantity of potentially moveable hydrocarbons. P(90) Estimate or Low Estimate: means at least a 90% probability that the quantities actually recovered will equal or exceed the estimate. P(50) Estimate or Best Estimate: means At least a 50% probability that the quantities actually recovered will equal or exceed the estimate. P(10) Estimate or High Estimate: means At least a 10% probability that the quantities actually recovered will equal or exceed the estimate. OIL AND GAS CONVERSIONS BOE means barrels of oil equivalent. Bcfe means billion of cubic feet of gas equivalent. Gas to oil conversion used in this presentation: 6 Mcf of gas = 1 barrel of oil.
