Horned Frog – Locator Map Gonzales Horned Frog Area Summary In March, 2015, Lonestar identified a 4,402-acre block held by Conoco-Phillips which was set to expire on July 5, 2015. On April 29, 2015, Lonestar farmed-in for 100% WI and delivered COP a 3.0% ORRI. Lonestar conducted a preliminary field study and determined that well results could be improved with proper geo-steering and higher proppant concentrations. Lonestar (100% WI) completed the A1H & B1H with perforated intervals of 8,233’ and 1,556 #/ft of proppant. Wells were steered within a petrophysically-derived 20-foot window. Average Max-30 day rates of 1,438 BOEPD (A1H) and 1,315 BOEPD (B1H) set records for the area. Lonestar (10% WI) drilled the D1H and E1H in 4Q15, and encountered significant geosteering challenges, and disappointing results. After HBP’ing the acreage, Lonestar commenced a more in-depth development optimization study. In May, 2017, LONE acquired an additional 1,070 net acres in the area. LONE has acquired the 3-D seismic across the greater Horned Frog acreage to prepare for development drilling in 2018.

Reserves Information Oil & Natural Gas Reserves This presentation provides disclosure of LONE’s proved reserves, which are those quantities of oil and natural 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 (using unweighted average 12-month first day of the month prices), 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. In this presentation, proved reserves attributable to LONE as of 6/30/17 are estimated utilizing SEC reserve recognition standards and pricing assumptions based on SEC pricing of (i) $48.95 / Bbl crude, $3.00 / MMBtu natural gas. References to our estimated proved reserves as of 6/30/17 are derived from our proved reserve reports prepared W.D. Von Gonten & Co. (“WDVG”). The average future prices for benchmark commodities used in determining our 11/6/17 Strip Pricing reserves were $57.09 for oil for 2017, $56.66 for 2018, $53.07 for 2019, $50.93 for 2020, $49.88 for 2021, $49.60 for 2022, $49.84 for 2023, $50.36 for 2024, $50.97 for 2025, $51.37 for 2026, and escalated 3% thereafter and $3.09/MMBtu for natural gas for 2017, $3.05 for 2018, $2.92 for 2019, $2.87 for 2020, $2.87 for 2021, $2.89 for 2022, $2.95 for 2023, $3.02 for 2024, $3.09 for 2025, $3.17 for 2026, and escalated 3% thereafter. We may use the term “expected ultimate recoveries” (“EURs”) or other descriptions of volumes of reserves, which terms include quantities of oil and natural gas that may not meet the SEC’s definitions of proved, probable and possible reserves, and which the SEC's guidelines strictly prohibit LONE from including in filings with the SEC. Unless otherwise stated in this presentation, such estimates have been prepared internally by our engineers and management without review by independent engineers. These estimates are by their nature more speculative than estimates of proved, probable and possible reserves and accordingly are subject to substantially greater risk of being actually realized, particularly in areas or zones where there has been limited or no drilling history. We include these estimates to demonstrate what we believe to be the potential for future drilling and production by the Company. Actual locations drilled and quantities that may be ultimately recovered from our properties will differ substantially. In addition, we have made no commitment to drill all of the drilling locations. Ultimate recoveries will be dependent upon numerous factors including actual encountered geological conditions, the impact of future oil and natural gas pricing, exploration and development costs, and our future drilling decisions and budgets based upon our future evaluation of risk, returns and the availability of capital and, in many areas, the outcome of negotiation of drilling arrangements with holders of adjacent or fractional interest leases. Our estimates may change significantly as development of our properties provide additional data and therefore actual quantities that may ultimately be recovered will likely differ from these estimates. Our related expectations for future periods are dependent upon many assumptions, including estimates of production decline rates from existing wells, the undertaking and outcome of future drilling activity and activity that may be affected by significant commodity price declines or drilling cost increases. Engineered Acreage is acreage to which Proved, Probable and/or Possible reserves have been assigned to drilling location on that acreage by our independent petroleum consultants Non-Engineered acreage is acreage to which Proved, Probable and/or Possible reserves have not been assigned to drilling location on that acreage by our independent petroleum consultants  

Non-GAAP Reconciliation Reconciliation of Non‐GAAP Financial Measures Adjusted EBITDAX Adjusted EBITDAX is not a measure of net income as determined by GAAP. Adjusted EBITDAX is a supplemental non‐GAAP financial measure that is used by management and external users of the Company’s consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. The Company defines Adjusted EBITDAX as net (loss) income before depreciation, depletion, amortization and accretion, exploration costs, non‐recurring costs, (gain) loss on sales of oil and natural gas properties, impairment of oil and gas properties, stock‐based compensation, interest expense, income tax (benefit) expense, rig standby expense, other income (expense) and unrealized (gain) loss on derivative financial instruments and unrealized (gain) loss on warrants. Management believes Adjusted EBITDAX provides useful information to investors because it assists investors in the evaluation of the Company’s operating performance and comparison of the results of the Company’s operations from period to period without regard to its financing methods or capital structure. The Company excludes the items listed above from net income in arriving at Adjusted EBITDAX to eliminate the impact of certain non‐cash items or 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. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP. Certain items excluded from 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 Adjusted EBITDAX. The Company’s computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies. The following table presents a reconciliation of Adjusted EBITDAX to the GAAP financial measure of net income (loss) for each of the periods indicated. 1 Interest expense consists of Amortization of finance costs and Dividends paid on the preferred stock 2 Represents a non‐recurring cost associated with a drilling rig contract 3 Non‐recurring costs consists of Acquisitions Costs and General and Administrative Expenses related to the re‐domiciliation to the United States, and listing on the NASDAQ.
