POTENTIAL ADDITIONAL NEW BLOCK – RANGKAS AREA An onshore area of 3,970 km2 (or 981,008 acres) adjacent to Citarum block with a proven petroleum system LOCATION AREA • Proved hydrocarbon generating province by the numerous oil/gas seeps within the Rangkas block • Occurrence of Eocene - Oligocene - Miocene Source, Reservoir and Seal rocks similar to adjacent major producing hydrocarbon areas in West Java • Multiple subbasins from geophysical data showing potential for higher chances of multiple hydrocarbon accumulations • Four pre - WWII wells and two 1991 wells have either flowed oil or indications of oil • A dozen prospects with individual closure area up to 3,700 acres have been identified with typical stacked reservoirs between 300m and 2,000m depth • Adoption of new seismic and geochemical technology would improve the probability of finding commercial hydrocarbon accumulations in the appraisal program ▪ IEC, through its subsidiary GWN, obtained approval to initiate the Joint Study program on November 5, 2018 ▪ If the Joint Study produces satisfying results, a PSC contract for the Rangkas Area would potentially be available through a direct tender process whereas GWN will have the right to match the best offer following the results of the bidding process ▪ The timeline for the tender is contingent upon the DGOG’s plans and schedule 22

Adjusted EBITDA and Adjusted EBITDA less capital expenditures are supplemental non - GAAP financial measures used by management and external users of our financial statements, such as industry analysts, investors, lenders and rating agencies . We define Adjusted EBITDA as earnings before interest expense, income taxes, depreciation, depletion, amortization and accretion, write down of other assets, and other unusual out of period and infrequent items . We define Adjusted EBITDA less capital expenditures as Adjusted EBITDA less capital expenditures . Our management believes Adjusted EBITDA provides useful information in assessing our financial condition, results of operations and cash flows and is widely used by the industry and the investment community . The measure also allows our management to more effectively evaluate our operating performance and compare the results between periods without regard to our financing methods or capital structure . Adjusted EBITDA less capital expenditures is used by management as a measure of cash generated by the business, after accounting for capital expenditures, available for investment, dividends, debt reduction or other purposes . While Adjusted EBITDA and Adjusted EBITDA less capital expenditures are non - GAAP measures, the amounts included in the calculation of Adjusted EBITDA and Adjusted EBITDA less capital expenditures were computed in accordance with GAAP . These measures are provided in addition to, and not as an alternative for, income and liquidity measures calculated in accordance with GAAP . Certain items excluded from Adjusted EBITDA are significant components in understanding and assessing our financial performance, such as our cost of capital and tax structure, as well as the historic cost of depreciable and depletable assets . Our computations of Adjusted EBITDA and Adjusted EBITDA less capital expenditures may not be comparable to other similarly titled measures used by other companies . Adjusted EBITDA and Adjusted EBITDA less capital expenditures should be read in conjunction with the information contained in our financial statements prepared in accordance with GAAP . 27 ( 1 ) The above table presents (i) a reconciliation of Adjusted EBITDA to the US GAAP financial measure of net income (loss) and (ii) a reconciliation of the US GAAP financial measure of net cash provided by (used in) operating activities to the non - GAAP financial measures of Adjusted EBITDA and Adjusted EBITDA less capital expenditures for each of the periods indicated .
