2 • The material that follows comprises information about GeoPark Limited (“GeoPark” or the “Company”) and its subsidiaries, as of the date of the presentation . It has been prepared solely for informational purposes and should not be treated as giving legal, tax, investment or other advice to potential investors . The information presented or contained herein is in summary form and does not purport to be complete . • No representations or warranties, express or implied, are made as to, and no reliance should be placed on, the accuracy, fairness, or completeness of this information . Neither GeoPark nor any of its affiliates, advisers or representatives accepts any responsibility whatsoever for any loss or damage arising from any information presented or contained in this presentation . The information presented or contained in this presentation is current as of the date hereof and is subject to change without notice, and its accuracy is not guaranteed . Neither GeoPark nor any of its affiliates, advisers or representatives makes any undertaking to update any such information subsequent to the date hereof . • This presentation contains forward - looking statements, which are based upon GeoPark and/or its management’s current expectations and projections about future events . When used in this presentation, the words “believe,” “anticipate,” “intend,” “estimate,” “expect,” “should,” “may” and similar expressions, or the negative of such words and expressions, are intended to identify forward - looking statements, although not all forward - looking statements contain such words or expressions . Additionally, all information, other than historical facts included in this presentation, regarding strategy, future operations, drilling plans, estimated reserves, estimated resources, future production, estimated capital expenditures, projected costs and costs reductions, cash flows or cash flows growth, GDP growth, the potential of drilling prospects, potential production from existing assets and other plans and objectives of management for 2019 and beyond is forward - looking information . Such statements and information are subject to a number of risks, uncertainties and assumptions . Forward - looking statements are not guarantees of future performance and actual results may differ materially from those anticipated due to many factors, including oil and natural gas prices, industry conditions, drilling results, uncertainties in estimating reserves and resources, availability and cost of drilling rigs, production equipment, supplies, personnel and oil field services, availability of capital resources and other factors . As for forward - looking statements that relate to future financial results and other projections, actual results may be different due to the inherent uncertainty of estimates, forecasts and projections . Because of these uncertainties, potential investors should not rely on these forward - looking statements . Neither GeoPark nor any of its affiliates, directors, officers, agents or employees, nor any of the shareholders or under shall be liable, in any event, before any third party (including investors) for any investment or business decision made or action taken in reliance on the information and statements contained in this presentation or for any consequential, special or similar damages . • Statements related to resources are deemed forward - looking statements as they involve the implied assessment, based on certain estimates and assumptions, that the resources will be discovered and can be profitably produced in the future . Specifically, forward - looking information contained herein regarding "resources" may include : estimated volumes and value of the Company's oil and gas resources and the ability to finance future development ; and, the conversion of a portion of resources into reserves . • The information included in this presentation regarding estimated quantities of proved, probable or possible reserves in Chile, Colombia, Brazil, and Peru as of December 31 , 2017 ; are derived, in part, from the reports prepared by DeGolyer and MacNaughton , or D&M, independent reserves engineers . Certified reserves refers to net reserves independently evaluated by the petroleum consulting firm, D&M . Certain reserves data, such as those based on the D&M report, were prepared under SEC standards, and certain other data were prepared under Petroleum Resources Management System (PRMS) standards . • The information included in this presentation regarding estimated exploration resources in Colombia, Chile, Brazil, and Peru as of December 31 , 2015 , 2016 or 2017 ; are derived, in part, from the reports prepared by Gaffney, Cline & Associates, or GCA . The accuracy of any resource estimate is a function of the quality of the available data and of engineering and geological interpretation . Results of drilling, testing and production that postdate the preparation of the estimates may justify revisions, some or all of which may be material . Accordingly, resource estimates are often different from the quantities of oil and gas that are ultimately recovered, and the timing and cost of those volumes that are recovered may vary from that assumed . • Prospective Resources are those quantities of petroleum that are estimated, as of a given date, to be potentially recoverable from undiscovered accumulations by application of future development projects . Prospective Resources have both an associated “chance of discovery” and a “chance of development” (per PRMS) . Prospective Resources are further subdivided in accordance with the level of certainty associated with recoverable estimates, assuming their discovery and development, and may be sub - classified based on project maturity . There is no certainty that any portion of the Prospective Resources will be discovered . If discovered, there is no certainty that it will be commercially viable to produce any portion of the resources . Prospective Resource volumes are presented as unrisked . The risk or chance of finding a minimum hydrocarbon volume that can flow to surface is presented as Geological Chance of Success ( GCoS ) . • Certain data in this presentation was obtained from various external sources, and neither GeoPark nor its affiliates, advisers or representatives has verified such data with independent sources . Accordingly, neither GeoPark nor any of its affiliates, advisers or representatives makes any representations as to the accuracy or completeness of that data, and such data involves risks and uncertainties and is subject to change based on various factors . • This presentation contains a discussion of Adjusted EBITDA, which is not an IFRS measure . We define Adjusted EBITDA as profit for the period before net finance cost, income tax, depreciation, amortization and certain non - cash items such as impairments and write - offs of unsuccessful exploration and evaluation assets, accrual of stock options and stock awards and bargain purchase gain on acquisition of subsidiaries . Adjusted EBITDA is included in this presentation because it is a measure of our operating performance and our management believes that Adjusted EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties in their evaluation of the operating performance of companies in industries similar to ours . Adjusted EBITDA should not be considered a substitute for financial information presented or prepared in accordance with IFRS . Adjusted EBITDA, as determined and measured by us, should also not be compared to similarly titled measures reported by other companies . • Rounding amounts and percentages : Certain amounts and percentages included in this document have been rounded for ease of presentation . Percentage figures included in this document have not in all cases been calculated on the basis of such rounded figures but on the basis of such amounts prior to rounding . For this reason, certain percentage amounts in this document may vary from those obtained by performing the same calculations using the figures in the financial statements . In addition, certain other amounts that appear in this document may not sum due to rounding . Disclaimer
