Exhibit 99.2

Disclaimer FORWARD LOOKING STATEMENTS The information in this presentation and the oral statements made in connection therewith include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). All statements, other than statements of present or historical fact included in this presentation, regarding TPG Pace Energy Holding Corp.’s (either as currently organized or as it may be reorganized in connection with the transactions contemplated in this presentation, “TPGE”) proposed acquisition of oil and gas assets from certain funds affiliated with EnerVest, Ltd. ( “EnerVest”), TPGE’s ability to consummate the transaction, the benefits of the transaction and TPGE’s future financial performance following the transaction, as well as TPGE’s strategy, future operations, financial position, estimated revenues, and losses, projected costs, prospects, plans and objectives of management are forward looking statements. When used in this presentation, including any oral statements made in connection therewith, the words “could,” “should,” “will,” “may,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project,” the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Except as otherwise required by applicable law, TPGE disclaims any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date of this presentation. TPGE cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of TPGE, incident to the development, production, gathering and sale of oil, natural gas and natural gas liquids. These risks include, but are not limited to, commodity price volatility, low prices for oil and/or natural gas, global economic conditions, inflation, increased operating costs, lack of availability of drilling and production equipment, supplies, services and qualified personnel, processing volumes and pipeline throughput, and certificates related to new technologies, geographical concentration of operations, environmental risks, weather risks, security risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating oil and natural gas reserves and in projecting future rates of production, reductions in cash flow, lack of access to capital, TPGE’s ability to satisfy future cash obligations, restrictions in existing or future debt agreements, the timing of development expenditures, managing growth and integration of acquisitions, failure to realize expected value creation from property acquisitions, the defects and limited control over non-operated properties. Should one or more of the risks or uncertainties described in this presentation and the oral statements made in connection therewith occur, or should underlying assumptions prove incorrect, actual results and plans could different materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact TPGE's operations and projections can be found in its periodic filings with the Securities and Exchange Commission (the "SEC"), including its Annual Report on Form 10-K for the fiscal year ended December 31, 2017. TPGE's SEC Filings are available publicly on the SEC"s website at www.sec.gov. RESERVE INFORMATION Reserve engineering is a process of estimating underground accumulations of hydrocarbons that cannot be measured in an exact way. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions of estimates that were made previously. If significant, such revisions could impact TPGE’s strategy and change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil and natural gas that are ultimately recovered. Estimated Ultimate Recoveries, or “EURs,” refers to estimates of the sum of total gross remaining proved reserves per well as of a given date and cumulative production prior to such given date for developed wells. These quantities do not necessarily constitute or represent reserves as defined by the SEC and are not intended to be representative of all anticipated future well results. USE OF PROJECTIONS This presentation contains projections for TPGE, including with respect to its EBITDA, net debt to EBITDA ratio, capital budget, free cash flow and operating margin as well as its production volumes. TPGE’s independent auditors have not audited, reviewed, compiled, or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, have not expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections are for illustrative purposes only and should not be relied upon as being necessary indicative of future results. In this presentation, certain of the above-mentioned projected information has been repeated (in each case, with an indication that the information is subject to the qualifications presented herein), for purposes of providing comparisons with historical data. Each of the assumptions and estimates underlying the projected information throughout this presentation are based on the data in Slides 18, 24-25. The assumptions and estimates underlying the projected information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projected information. Even of our assumptions and estimates are correct, projections are inherently uncertain due to a number of factors outside our control. Accordingly, there can be no assurance that the projected results are indicative of the future performance of TPGE after completion of the transaction or that actual results will not differ materially from those presented in the projected information. Inclusions of the projected information in this presentation should not be regarded as a representation by any person that the results contained in the projected information will be achieved. USE OF NON-GAAP FINANCIAL MEASURES This presentation, including the “Magnolia Financial Projections” shown on slide 25 hereof, includes non-GAAP financial measures, including EBITDA, Adjusted EBITDAX and free cash flow of TPGE. TPGE believes EBITDA, Adjusted EBITDAX and free cash flow are useful because they allow TPGE to more effectively evaluate its operating performance and compare the results of its operations from period to period and against its peers without regard to financing methods or capital structure. TPGE does not consider these non-GAAP measures in isolation or as an alternative to similar financial measures determined in accordance with GAAP. The computations of EBITDA, Adjusted EBITDAX and free cash flow may not be comparable to other similarly titled measures of other companies. TPGE excludes certain items from net (loss) income in arriving at EBITDA and Adjusted EBITDAX because these amounts can vary substantially from company to company within its industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. EBITDA and Adjusted EBITDAX should not be considered as alternatives to, or more meaningful than, net income as determined in accordance with GAAP or as indicators of operating performance. Certain items excluded from EBITDA and Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of EBITDA or Adjusted EBITDAX. TPGE’s presentation of EBITDA and Adjusted EBITDAX should not be construed as an inference that its results will be unaffected by unusual or non-recurring terms. TPGE excludes capital expenditures from its cash flows from operations in arriving at its free cash flow in order to provide an understanding of certain factors and trends affecting its cash flows and liquidity. Free cash flow does not represent the residual cash flow available for discretionary expenditures. TPGE believes that free cash flow is useful to investors as a measure of the ability of its business to generate cash. INDUSTRY AND MARKET DATA This presentation has been prepared by TPGE and includes market data and other statistical information from sources believed by TPGE to be reliable, including independent industry publications, governmental publications or other published independent sources. Some data is also based on the good faith estimates of TPGE, which are derived from its review of internal sources as well as the independent sources described above. Although TPGE believes these sources are reliable, it has not independently verified the information and cannot guarantee its accuracy and completeness. TRADEMARKS AND TRADE NAMES TPGE and EnerVest own or have rights to various trademarks, service marks and trade names that they use in connection with the operation of their respective businesses. This presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners.

Steve Chazen and TPG raised $650 million through the IPO of a special purpose acquisition company (“SPAC”) in May 2017, called TPG Pace Energy Holdings Corp. (“Pace Energy” or “TPGE”) Pace Energy was established to build a large scale, focused oil & gas business with a meaningful production base, strong free cash flow and a disciplined corporate philosophy Pace Energy has entered into an agreement with EnerVest to carve-out EnerVest’s Eagle Ford and Giddings assets (the “South Texas Division”) and create Magnolia Oil & Gas Corporation (“Magnolia”) Pace Energy expects to acquire the South Texas Division for ~$2.66 billion(1), which represents an attractive entry multiple of ~5.0x 2018 Debt Adj. EV / EBITDA and an ~10% 2018E free cash flow yield after capital requirements EnerVest’s existing owners will retain a significant ownership in Magnolia The transaction delivers on all criteria from the Steve Chazen playbook and is expected to create a large scale, pure-play Eagle Ford / Austin Chalk operator with a clean balance sheet In connection with the transaction, TPGE has raised a $355 million PIPE of common equity at $10/share, in a placement anchored by certain funds and accounts managed by Fidelity Management & Research Company, Davis Selected Advisers, L.P. and certain funds managed by Capital Research and Management Company and that included several other leading institutional investors, as well as a $25 million personal investment from Steve Chazen and certain TPG executives. The public float after giving effect to this private placement is expected to be approximately $1 billion. Steve Chazen will be the full-time Chairman, President and CEO; Chris Stavros, former CFO of Occidental Petroleum, will be joining as full-time CFO, and Magnolia will maintain a majority independent Board of Directors Under Steve Chazen’s leadership, Magnolia will optimize EnerVest’s South Texas Division to create a strong platform to create shareholder value Transaction Summary Note: See slide 25 (Financial Projections) for information regarding EBITDA and cash flow projections.
