June 30, 2020 Sasol Canada 1600, 215 – 9th Avenue SW Calgary, Alberta T2P 1K3 Attention: Mr. Mathew Schraven, Asset Manager & Country President Reference: Sasol Canada Evaluation of Petroleum Reserves Supplied Prices and Costs Dear Sir: Pursuant to your request, we have prepared an evaluation of the proved petroleum reserves and the net present values of these reserves for the petroleum interests of Sasol Canada, hereinafter referred to as the "Company", as of June 30, 2020. The reserve estimates and future net revenue forecasts have been prepared and presented in accordance with U.S. Securities Exchange Commission (SEC) standards. The future net revenues and net present values presented in this report were calculated using supplied prices and costs based on the average first-day-of-the-month petroleum product prices for the last 6 months of 2019 and the first 6 months of 2020 with no inflation of operating or capital costs and were presented in Canadian dollars. Most of the future net revenues and net present value estimates in this report are presented before income taxes, although future net revenues and net present value estimates were presented after income tax in selected tables in this summary report at the corporate level. The future net revenues presented in this report may not necessarily represent the fair market value of the reserves estimates. The properties evaluated in this report were indicated to include essentially all of the Company's petroleum interests in Canada. The principal natural gas properties are located in the Farrell Creek and Cypress A areas in the Province of British Columbia. The Company's share of remaining reserves and net present values are presented on a total Company basis in the summary section of this report. The location of the Company’s properties and a summary of the forecast production, net revenue and reserves distributions are presented graphically in the summary section. Tables summarizing the reserves, production and revenues for the various reserve classes are presented in Appendices 1 to 3. A summary of the Company’s interests and burdens in each property is presented in Appendix 4. Discussions of the assumptions and methodology employed to prepare the reserves estimates and future revenue forecasts are also contained in the "Evaluation Methodology" section. 2200, Bow Valley Square 3, 255 - 5 Avenue SW, Calgary AB T2P 3G6Tel: (403) 262-5506Fax: (403) 233-2744www.mcdan.com

SASOL CANADA CYPRESS AND FARRELL CREEK AREAS Evaluation of Petroleum Reserves Based on Supplied Prices and Costs As of June 30, 2020 Evaluation Methodology INTRODUCTION Estimates of the proved petroleum reserves and the associated net present values before income taxes and after income taxes attributable to the properties of the Company have been presented in this report as of June 30, 2020. Reserves estimates were prepared for two properties in which the Company was indicated to have an interest in Western Canada based on detailed studies of the reservoir and performance characteristics as well as historical revenues and costs. The basic information employed in the preparation of this report was obtained from the Company's files, public sources and from our own non-confidential files. A field inspection of the properties was not conducted in view of the generally accepted reliability of the data sources for Western Canadian properties. Detailed reserve estimates, future net revenue forecasts and other supporting data for each of the entities that were reviewed in detail were provided in the Detailed Property Report. Property discussions and a detailed description of the economic factors employed to derive the future net revenue forecasts were also included in the Detailed Property Report. The effective date of this report is June 30, 2020. The reserve estimates presented herein were based on the operating and economic conditions and development status as of that date except for changes planned for the immediate future or in the process of implementation. The reserve estimates and future net revenue forecasts have been prepared and presented in accordance with U.S. Securities Exchange Commission (SEC) standards. A brief review of the methodology employed in arriving at the reserves and net present value estimates is presented in this section. RESERVES ESTIMATES Natural Gas and Products The natural gas reserve estimates for non-associated gas and gas cap pools were based on a study of the volumetric data and performance characteristics of the individual wells and reservoirs in question. Volumetric estimates of the initial gas in-place were based on individual well petrophysical interpretations, geological studies of the pools and areas, and in some cases on published estimates. Material balance estimates of the initial gas in-place were employed where sufficient information was available for a reliable estimate. The reserves recoverable from the currently producing properties were estimated from studies of production performance characteristics and/or reservoir pressure histories. In those cases where indicative

Sasol Canada Supplied Prices and Costs Page 2 June 30, 2020 gas production decline and/or increasing oil-gas ratio and water-gas ratio trends were evident, the remaining reserves were determined by extrapolating these trends to economic limiting conditions. In cases of competitive drainage in multi-well pools the reserves were based on an analysis of the relevant factors relating to the future pool depletion by existing and possible future wells. The recovery factors for the non-producing properties were estimated from a consideration of test rates, reservoir pressures and by analogy with similar wells or reservoirs. The natural gas products reserve estimates for the producing properties were based on historical and anticipated future recoveries of these products from the natural gas reserves. The natural gas products recoveries from the non-producing natural gas reserves were estimated from gas analyses, well test information and from analogy with similar reservoirs. Natural gas products reserves were only assigned to non-producing properties in those cases where there was a likelihood that the gas production would be processed through existing facilities capable of extracting these products or where such a facility will be available in the near future. SEC RESERVES DEFINITIONS The proved reserves and net present values estimates presented in this report were prepared to comply with the United States Securities and Exchange Commission (SEC) reserves definitions. Proved oil and gas reserves. Proved oil and gas reserves are those quantities of oil and gas, which, by analysis of geoscience and engineering data, can be estimated with reasonable certainty to be economically producible—from a given date forward, from known reservoirs, and under existing economic conditions, operating methods, and government regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. (i) The area of the reservoir considered as proved includes: a.The area identified by drilling and limited by fluid contacts, if any, and b. Adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible oil or gas on the basis of available geoscience and engineering data. (ii) In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons (LKH) as seen in a well penetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.

Sasol Canada Supplied Prices and Costs Page 3 June 30, 2020 (iii) Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geoscience, engineering, or performance data and reliable technology establish the higher contact with reasonable certainty. (iv) Reserves which can be produced economically through application of improved recovery techniques (including, but not limited to, fluid injection) are included in the proved classification when: a.Successful testing by a pilot project in an area of the reservoir with properties no more favorable than in the reservoir as a whole, the operation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes the reasonable certainty of the engineering analysis on which the project or program was based; and b. The project has been approved for development by all necessary parties and entities, including governmental entities. (v) Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. The price shall be the average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweighted arithmetic average of the first-day-of-the-month price for each month within such period, unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. Developed oil and gas reserves. Developed oil and gas reserves are reserves of any category that can be expected to be recovered: (i) Through existing wells with existing equipment and operating methods or in which the cost of the required equipment is relatively minor compared to the cost of a new well; and (ii) Through installed extraction equipment and infrastructure operational at the time of the reserves estimate if the extraction is by means not involving a well. Undeveloped oil and gas reserves. Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. (i) Reserves on undrilled acreage shall be limited to those directly offsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishes reasonable certainty of economic producibility at greater distances.

Sasol Canada Supplied Prices and Costs Page 4 June 30, 2020 (ii)Undrilled locations can be classified as having undeveloped reserves only if a development plan has been adopted indicating that they are scheduled to be drilled within five years, unless the specific circumstances, justify a longer time. (iii)Under no circumstances shall estimates for undeveloped reserves be attributable to any acreage for which an application of fluid injection or other improved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogous reservoir, or by other evidence using reliable technology establishing reasonable certainty. Reasonable certainty. If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will be recovered. If probabilistic methods are used, there should be at least a 90 percent probability that the quantities actually recovered will equal or exceed the estimate. A high degree of confidence exists if the quantity is much more likely to be achieved than not, and, as changes due to increased availability of geoscience (geological, geophysical, and geochemical), engineering, and economic data are made to estimated ultimate recovery (EUR) with time, reasonably certain EUR is much more likely to increase or remain constant than to decrease. NET PRESENT VALUE ESTIMATES The net present values of the petroleum reserves were obtained by employing future production and revenue analyses. The future natural gas production was also predicated on the anticipated performance characteristics of the individual wells and reservoirs in question with an allowance for any gas sales contract or gas processing facility restrictions. In those areas where shut-in natural gas reserves exist, the commencement of production was based on the proximity to a pipeline connection and the relevant factors relating to the future marketing of the reserves. The natural gas products production forecasts were based on the anticipated recoveries of these products from the produced natural gas. The indicated natural gas prices with an adjustment for the heating value of the gas were employed to calculate the Company’s share of future natural gas revenues. The indicated reference natural gas products prices with adjustments to reflect historical price differentials realized by the Company in each respective property were employed to calculate the Company’s share of future natural gas products revenues. Royalties and mineral taxes payable to the Crown were estimated based on the methods in effect as of June 30, 2020. Freehold and overriding royalties payable to others were estimated based on the indicated applicable rates. In those cases where a proportionate share of the natural gas gathering and processing charges were indicated to be payable by the Crown or royalties owned by others, these charges have been deducted in determining the net royalties payable. In all cases, estimates of the applicable capital expenditures and operating costs with no allowance for inflation were deducted in arriving at the Company's share of future net revenues. An allowance for future abandonment, decommissioning and reclamation (ADR) costs were included in this report. ADR costs include but are not limited to items such as: producing wells, suspended wells, service wells, gathering

Sasol Canada Supplied Prices and Costs Page 5 June 30, 2020 systems, facilities, and surface land development. These costs and their respective timing have been supplied and represented by the Company and incorporated into this report without review. The ADR costs were included for all Company properties. The net present values were then obtained by employing 5, 10, 15 and 20 percent nominal annual discount rates compounded monthly. The Company's share of remaining reserves and net present values are presented on a total Company basis in the summary section of this report. Most of the future net revenues and net present values estimated in this report are presented before income taxes. Future net revenues and net present values are presented after income tax in selected tables at the corporate level. The estimates of future income taxes were based on our understanding of current Canadian Oil and Gas tax calculations; however, income tax experts should be consulted before relying on any of the income tax estimates presented in this report. Summaries of the Company's share of remaining reserves together with forecast future revenues, royalties, taxes, operating and capital costs, abandonments, decommissioning and reclamation costs, future net revenue, and net present values are presented in detailed tabulations for each reserves category in Appendices 1 to 3.
