These forward-looking statements are made as of the date of this document and Parex disclaims any intent or obligation to update publicly any forward-looking statements, whether as a result of new information, future events or results or otherwise, other than as required by applicable securities laws. The forward-looking statements contained in this presentation are expressly qualified by this cautionary statement. Corporate Presentation April Corporate 2018 Presentation March 2017 24 24

ADVISORIES This document also contains a financial outlook, in particular the information set forth on slides 2-5 & 7. Such financial outlook has been prepared by Parex' management to provide an outlook of the Company's activities and results. The financial outlook has been prepared based on a number of assumptions including the assumptions discussed above and assumptions with respect to the costs and expenditures to be incurred by the Company, capital equipment and operating costs, foreign exchange rates, taxation rates for the Company, general and administrative expenses and the prices to be paid for the Company's production. Management does not have firm commitments for all of the costs, expenditures, prices or other financial assumptions used to prepare the financial outlook or assurance that such operating results will be achieved and, accordingly, the complete financial effects of all of those costs, expenditures, prices and operating results are not objectively determinable. The actual results of operations of the Company and the resulting financial results will likely vary from the amounts set forth in the analysis presented in this presentation, and such variation may be material. The Company and its management believe that the financial outlook has been prepared on a reasonable basis, reflecting the best estimates and judgments, and represent, to the best of management's knowledge and opinion, Parex's expected expenditures and results of operations. However, because this information is highly subjective and subject to numerous risks including the risks discussed above, it should not be relied on as necessarily indicative of future results. Except as required by applicable securities laws, Parex undertakes no obligation to update such financial outlook. Oil and Gas Information The estimates of Parex' December 31, 2017 reserves set forth in this presentation have been prepared by GLJ Petroleum Consultants Ltd. ("GLJ") as of December 31, 2017 with a preparation date of February 2, 2017 (the "GLJ 2017 Report") in accordance with National Instrument 51-101 Standards of Disclosure for Oil and Gas Activities ("NI 51-101") and the Canadian Oil and Gas Evaluations Handbook (the "COGEH") and using GLJ's forecast prices and costs as at January 1, 2018. The estimates of Parex' December 31, 2016 reserves set forth in this presentation have been prepared by GLJ as of December 31, 2016 with a preparation date of February 6, 2017 in accordance with NI 51-101 and the COGEH and using GLJ's forecast prices and costs as at January 1, 2017. The estimates of Parex' December 31, 2015 reserves set forth in this presentation have been prepared by GLJ as of December 31, 2015 with a preparation date of February 5, 2016 in accordance with NI 51-101 and the COGEH and using GLJ's forecast prices and costs as at January 1, 2016. The estimates of Parex' December 31, 2014 reserves set forth in this presentation have been prepared by GLJ as of December 31, 2014 with a preparation date of February 13, 2015 in accordance with NI 51-101 and the COGEH and using GLJ's forecast prices and costs as at January 1, 2015. The estimates of Parex' December 31, 2013 reserves set forth in this presentation have been prepared by GLJ as of December 31, 2013 with a preparation date of February 20, 2014 in accordance with NI 51-101 and the COGEH and using GLJ's forecast prices and costs as at January 1, 2014. Possible reserves are those additional reserves that are less certain to be recovered than probable reserves. There is a 10 percent probability that the quantities actually recovered will equal or exceed the sum of proved plus probable plus possible reserves. Estimates of the net present value of the future net revenue from Parex' reserves do not represent the fair market value of Parex' reserves. The estimates of reserves and future net revenue from individual properties or wells may not reflect the same confidence level as estimates of reserves and future net revenue for all properties and wells, due to the effects of aggregation. This presentation contains certain oil and gas metrics, including F&D, FD&A, FD&A/boe, reserves life index (or RLI), operating netbacks, cash netbacks, funds flow from operations netback, and recycle ratios, which do not have standardized meanings or standard methods of calculation and therefore such measures may not be comparable to similar measures used by other companies and should not be used to make comparisons. Such metrics have been included herein to provide readers with additional measures to evaluate the Company's performance; however, such measures are not reliable indicators of the future performance of the Company and future performance may not compare to the performance in previous periods and therefore such metrics should not be unduly relied upon. Management uses these oil and gas metrics for its own performance measurements and to provide investors with measures to compare the Company's operations over time.

ADVISORIES Readers are cautioned that the information provided by these metrics, or that can be derived from the metrics presented herein, should not be relied upon for investment or other purposes. A summary of the calculations of such metrics are as follows: o o o o o o FD&A costs represent the costs of property acquisition, exploration, and development incurred. The aggregate of the exploration and development costs incurred in the most recent financial year and the change during that year in estimated future development costs generally will not reflect total finding and development costs related to reserves additions for that year. FD&A costs are calculated as capital expenditures plus change in F&D costs. FD&A per boe is calculated as FD&A costs divided by reserves additions for the applicable period. Reserves life index is calculated as proved plus probable reserves divided by annualized fourth quarter production. Recycle ratio is calculated as cash netback per boe (or Funds Flow From Operations per boe) divided by F&D or FD&A, as applicable. Cash netback per boe (or Funds Flow From Operations netback per boe) is calculated as Funds Flow From Operations divided by production for the period. Operating netback is calculated as oil & gas revenue less expenses (royalties, production and transportation) divided by production for the period. "BOEs" may be misleading, particularly if used in isolation. A BOE conversion ratio of six thousand cubic feet of natural gas to one barrel of oil equivalent (6 mcf: 1 bbl) is based on an energy equivalency conversion method primarily applicable at the burner tip and does not represent a value equivalency at the wellhead. Given that the value ratio based on the current price of crude oil as compared to natural gas is significantly different from the energy equivalency of 6:1, utilizing a conversion on a 6:1 basis may be misleading as an indication of value. All of Parex crude oil reserves disclosed herein are located in Colombia. The Company does have light, medium and heavy crude oil and natural gas liquids. The recovery and reserve estimates of crude oil reserves provided in this document are estimates only, and there is no guarantee that the estimated reserves will be recovered. Actual crude oil reserves may eventually prove to be greater than, or less than, the estimates provided herein. All evaluations and reviews of future net revenue contained in GLJ's reports are stated prior to any provision for interest costs or general and administrative costs and after the deduction of royalties, development costs, production costs, well abandonment costs and estimated future capital expenditures for wells to which reserves have been assigned. This presentation discloses drilling locations in three categories: (i) proved locations; (ii) probable locations; and (iii) possible locations. Proved locations, probable locations and possible locations are derived from the GLJ 2017 Report and account for drilling locations that have associated proved and/or probable and/or possible reserves, as applicable. Of the 191 drilling locations identified herein, 115 are proved locations, 43 are probable locations and 33 are possible locations. The drilling locations on which the Company actually drills wells will ultimately depend upon the availability of capital, regulatory approvals, seasonal restrictions, oil prices, costs, actual drilling results, additional reservoir information that is obtained and other factors. Further, this presentation includes estimates of pay thickness, which are considered to be anticipated results or information that indicate the potential value or quantities of resources under NI 51-101. Such estimates have been prepared internally by Parex by a non-independent qualified reserves evaluator and have not been prepared or reviewed by an independent qualified reserves evaluator or auditor. The risks associated with these estimates include, but are not limited to, the risk that Parex' exploration and development drilling and related activities may provide different results; the risk that Parex may encounter unexpected drilling results; the occurrence of unexpected events involved in the exploration for, and the operation and development of, oil and gas; delays in anticipated timing of drilling and completion of wells; geological, technical, drilling and processing problems and other difficulties in producing petroleum reserves; and the risk that if any resources are discovered that it will not be commercially viable to produce any portion thereof. There is no certainty that Parex will achieve the estimated results or that any portion of the resources will be discovered. If discovered, there is also no certainty that it will be commercially viable to produce any portion of the resources. Corporate Presentation April Corporate 2018 Presentation March 2017 26 26

If discovered, there is also no certainty that it will be commercially viable to produce any portion of the resources. Certain information in this document may constitute "analogous information" as defined in NI 51-101. Such information includes production estimates, drilling results, test rates, reserves estimates and other information retrieved from other publicly available sources, including but not limited to IHS. Management of Parex believes the information is relevant as it may help to define the reservoir characteristics and production profile of lands in which Parex may hold an interest. Parex is unable to confirm that the analogous information was prepared by a qualified reserves evaluator or auditor and is unable to confirm that the analogous information was prepared in accordance with NI 51-101. Such information is not an estimate of the production, reserves or resources attributable to lands held or to be held by Parex and there is no certainty that the production, reserves or resources data and economic information for the lands held or to be held by Parex will be similar to the information presented herein. The reader is cautioned that the data relied upon by Parex may be in error and/or may not be analogous to such lands held or to be held by Parex. Certain other information contained in this presentation has been prepared by third-party sources, which information has not been independently audited or verified by Parex. No representation or warranty, express or implied, is made by Parex as to the accuracy or completeness of the information contained in this document, and nothing contained in this presentation is, or shall be relied upon as, a promise or representation by Parex. This presentation contains references to type well production and economics, which are derived, at least in part, from available information respecting the well economics of other companies and, as such, there is no guarantee that Parex will achieve the stated or similar results, capital costs and return costs representative per well. References in this presentation to initial production test rates, initial "flow" rates, initial flow testing, and "peak" rates are useful in confirming the presence of hydrocarbons, however such rates are not determinative of the rates at which such wells will commence production and decline thereafter and are not indicative of long term performance or of ultimate recovery. While encouraging, investors are cautioned not to place reliance on such rates in calculating the aggregate production for Parex. Parex has not conducted a pressure transient analysis or well-test interpretation on the wells referenced in this presentation. As such, all data should be considered to be preliminary until such analysis or interpretation has been done. Financial Matters The Company discloses several financial measures that do not have any standardized meaning prescribed under International Financial Reporting Standards ("IFRS"). These financial measures include operating netbacks, cash netbacks, funds flow netbacks and funds flow from operations. Management believes that these financial measures are useful supplemental information to analyze operating performance and provide an indication of the results generated by the Company s principal business activities. Investors should be cautioned that these measures should not be construed as an alternative to net income or other measures of financial performance as determined in accordance with IFRS. Parex s method of calculating these measures may differ from other companies, and accordingly, they may not be comparable to similar measures used by other companies. Please see the Company s most recent Management s Discussion and Analysis, which is available at www.sedar.com for additional information about these financial measures.
