SUPPLEMENTARY INFORMATION ON OIL AND NATURAL GAS EXPLORATION, DEVELOPMENT AND PRODUCTION ACTIVITIES (UNAUDITED) | The following supplementary information concerning the Company’s oil and natural gas exploration, development and production activities reflects only those of Davis in the year ended December 31, 2015. Information at and for the year ended December 31, 2016 combines Davis’ reserve and other information with that of Yuma California resulting from the Davis Merger. Reserves Proved natural gas and oil reserves are those quantities of natural gas and oil, which, by analysis of geosciences 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. Existing economic conditions include prices and costs at which economic producibility from a reservoir is to be determined. Based on reserve reporting rules, the price is calculated using 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 (if the first day of the month occurs on a weekend or holiday, the previous business day is used), unless prices are defined by contractual arrangements, excluding escalations based upon future conditions. A project to extract hydrocarbons must have commenced or the operator must be reasonably certain that it will commence the project within a reasonable time. The area of the reservoir considered as proved includes: (i) the area identified by drilling and limited by fluid contacts, if any, and (ii) adjacent undrilled portions of the reservoir that can, with reasonable certainty, be judged to be continuous with it and to contain economically producible natural gas or oil on the basis of available geosciences and engineering data. In the absence of data on fluid contacts, proved quantities in a reservoir are limited by the lowest known hydrocarbons as seen in a well penetration unless geosciences, engineering or performance data and reliable technology establish a lower contact with reasonable certainty. Where direct observation from well penetrations has defined a highest known oil elevation and the potential exists for an associated natural gas cap, proved oil reserves may be assigned in the structurally higher portions of the reservoir only if geosciences, engineering or performance data and reliable technology establish the higher contact with reasonable certainty. Developed natural gas and oil reserves are reserves of any category that can be expected to be recovered 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. The information below on the Company’s natural gas and oil reserves is presented in accordance with regulations prescribed by the SEC, with guidelines established by the Society of Petroleum Engineers’ Petroleum Resource Management System, as in effect as of the date of such estimates. The Company’s reserve estimates are generally based upon extrapolation of historical production trends, analogy to similar properties and volumetric calculations. Accordingly, these estimates will change as future information becomes available and as commodity prices change. Such changes could be material and could occur in the near term. The Company does not prepare engineering estimates of proved oil and natural gas reserve quantities for all wells as some wells are shut in or uneconomic and do not conform to SEC classifications. Internal Controls Over Reserve and Future Net Revenue Estimation The Company’s principal engineer is the Executive Vice President and Chief Operating Officer and is the person primarily responsible for overseeing the preparation of the Company’s internal reserve estimates and for overseeing the independent petroleum engineering firm during the preparation of the Company’s reserve report. His experience includes, among other things, detailed evaluation of reserves and future net revenues for acquisitions, divestments, bank financing, long range planning, portfolio optimization, strategy and end of year financial reports. He has a B.S. in Petroleum Engineering from Louisiana Tech University and is a member of the Society of Petroleum Engineers (the “SPE”). His professional qualifications meet or exceed the qualifications of reserve estimators and auditors set forth in the “Standards Pertaining to Estimation and Auditing of Oil and Gas Reserves Information” promulgated by the SPE. The Executive Vice President and Chief Operating Officer reports directly to the Company’s Chief Executive Officer. At December 31, 2016 and 2015, Netherland, Sewell & Associates, Inc. (“NSAI”) performed an independent engineering evaluation in accordance with the definitions and regulations of the SEC to obtain an independent estimate of the Company’s proved reserves and future net revenues. Third Party Procedures and Methods Review In preparation of the reserve report, NSAI’s review consisted of 34 fields which included the Company’s major assets in the United States and encompassed 100 percent of the Company’s proved reserves and future net cash flows as of December 31, 2016 and 2015. The Chief Operating Officer and the reservoir engineering staff presented NSAI with an overview of the data, methods and assumptions used in estimating reserves and future net revenues for each field. The data presented included pertinent seismic information, geologic maps, well logs, production tests, material balance calculations, well performance data, operating expenses and other relevant economic criteria. Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves The following information has been developed utilizing procedures from the FASB concerning disclosures about oil and gas producing activities, and based on natural gas and crude oil reserve and production volumes estimated by the Company’s engineering staff. It can be used for some comparisons, but should not be the only method used to evaluate the Company or its performance. Further, the information in the following table may not represent realistic assessments of future cash flows, nor should the standardized measure of discounted future net cash flows be viewed as representative of the current value of the Company. The Company believes that the following factors should be taken into account when reviewing the following information: ● future costs and oil and natural gas sales prices will probably differ from the average annual prices required to be used in these calculations; ● due to future market conditions and governmental regulations, actual rates of production in future years may vary significantly from the rate of production assumed in the calculations; ● a 10 percent discount rate may not be reasonable as a measure of the relative risk inherent in realizing future net oil and gas revenues; and ● future net revenues may be subject to different rates of income taxation. The standardized measure of discounted future net cash flows relating to the Company’s ownership interests in proved crude oil and natural gas reserves as of year-end is shown for the Company for fiscal years 2016 and 2015. Oil and Natural Gas Exploration and Production Activities Oil and natural gas sales reflect the market prices of net production sold or transferred with appropriate adjustments for royalties, net profits interest, and other contractual provisions. Lease operating expenses include lifting costs incurred to operate and maintain productive wells and related equipment including such costs as operating labor, repairs and maintenance, materials, supplies, and fuel consumed. Production taxes include production and severance taxes. Depletion of oil and natural gas properties relates to capitalized costs incurred in acquisition, exploration, and development activities. Results of operations do not include interest expense and general corporate amounts. Costs Incurred and Capitalized Costs The costs incurred in oil and natural gas acquisition, exploration, and development activities are as follows: Years Ended December 31, 2016 2015 Costs incurred for the year: Exploration (including geological and geophysical costs) $ 23,000 $ — Development 8,268,653 3,847,000 Acquisition of properties, net (1) 55,479,000 1,401,000 Capitalized overhead 3,688,642 1,502,000 Lease acquisition costs, net of recoveries 670,514 899,000 Total costs incurred $ 68,129,809 $ 7,649,000 (1) Acquisition costs incurred during 2016 consisted entirely of assets acquired in the Davis Merger described in Note 4 - Acquisitions and Divestments. During the years ended December 31, 2016 and 2015, total costs incurred included estimated cost of future abandonment of $6.5 million and $0.8 million, respectively. Capitalized costs for oil and natural gas properties are as follows: December 31, 2016 2015 Oil and natural gas properties Capitalized Unproved properties $ 3,656,989 $ 178,761 Proved properties 488,723,905 425,767,477 Total oil and gas properties 492,380,894 425,946,238 Less accumulated DD&A (410,440,433 ) (381,987,616 ) Net oil and natural gas properties capitalized $ 81,940,461 $ 43,958,622 Oil and Natural Gas Reserves and Related Financial Data The following tables present the Company’s independent petroleum engineers’ estimates of proved oil and natural gas reserves, all of which are located in the United States of America. The Company emphasizes that reserves are estimates that are expected to change as additional information becomes available. Reservoir engineering is a subjective process of estimating underground accumulations of oil and natural gas that cannot be measured in an exact way and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Proved reserves are estimated quantities of natural gas and crude oil which geological and engineering data indicate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic and operating conditions. Proved developed reserves are proved reserves that can be expected to be recovered through existing wells with existing equipment and operating methods.

The Company elected not to extend its Masters Creek acreage associated with these reserves due to the depressed price environment and The Company’s inability to attract a joint venture partner. The twelve-month unweighted arithmetic average of the first-day-of-the-month reference prices used in the Company’s reserve estimates at December 31, 2016 and 2015 were $2.48/MMbtu and $42.75/Bbl (West Texas Intermediate) and $2.59/MMbtu and $50.28/Bbl (West Texas Intermediate), respectively, for natural gas and oil, respectively. Standardized Measure of Discounted Future Net Cash Flows The following table presents a standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves. Future cash flows were computed by applying year-end prices of oil and natural gas, which are adjusted for applicable transportation and quality differentials, to the estimated year-end quantities of those reserves. Future production and development costs were computed by estimating those expenditures expected to occur in developing and producing the proved oil and natural gas reserves at the end of the year, based on year-end costs. Actual future cash flows may vary considerably, and the standardized measure does not necessarily represent the fair value of the Company’s oil and natural gas reserves. Year Ended December 31, 2016 2015 Future cash inflows $ 200,115,200 $ 112,448,800 Future oil and natural gas operating expenses (67,735,300 ) (38,403,800 ) Future development costs (32,071,500 ) (21,947,100 ) Future income tax expenses — — Future net cash flows 100,308,400 52,097,900 10% annual discount for estimated timing of cash flows (26,708,300 ) (11,117,800 ) Standardized measure of discounted future net cash flows $ 73,600,100 $ 40,980,100 A summary of the changes in the standardized measure of discounted future net cash flows applicable to proved natural gas and crude oil reserves follows: Year Ended December 31, 2016 2015 January 1 $ 40,980,100 $ 101,671,500 Changes due to current year operation: Sales of oil and natural gas, net of oil and natural gas operating expenses (5,433,825 ) (10,769,400 ) Extensions and discoveries 2,739,700 3,534,100 Purchases of oil and natural gas properties 45,762,176 1,062,200 Development costs incurred during the period that reduced future development costs 7,077,036 2,094,500 Changes due to revisions in standardized variables: Prices and operating expenses (12,181,580 ) (66,321,100 ) Income taxes — — Estimated future development costs 1,915,239 15,321,900 Quantity estimates (7,876,109 ) (12,951,100 ) Sale of reserves in place (2,243,256 ) (2,784,500 ) Accretion of discount 4,098,010 10,167,200 Production rates, timing and other (1,237,391 ) (45,200 ) Net change 32,620,000 (60,691,400 ) December 31 $ 73,600,100 $ 40,980,100 |
