Regulations of many states require plugging of abandoned wells.“Pooling.” Pooling, either contractually or statutorily through regulatory actions, allows an operator to combine multiple leased tracts to create agovernmental spacing unit for one or more productive formations. (Pooling is also known as unitization or communitization.). Ownership interests arecalculated within the pooling/spacing unit according to the net acreage contributed by each tract within the pooling/spacing unit.“Possible reserves.” Those additional reserves that are less certain to be recovered than probable reserves.“Probable reserves.” Those additional reserves that are less certain to be recovered than proved reserves but which, together with proved reserves,are as likely as not to be recovered.“Production costs.” Costs incurred to operate and maintain wells and related equipment and facilities, including depreciation and applicableoperating costs of support equipment and facilities and other costs of operating and maintaining those wells and related equipment and facilities. Theybecome part of the cost of oil and gas produced. Examples of production costs (sometimes called lifting costs) are (a) costs of labor to operate the wells andrelated equipment and facilities; (b) repairs and maintenance; (c) materials, supplies, and fuel consumed and supplies utilized in operating the wells andrelated equipment and facilities; (d) property taxes and insurance applicable to proved properties and wells and related equipment and facilities; and (e)severance taxes. Some support equipment or facilities may serve two or more oil and gas producing activities and may also serve transportation, refining, andmarketing activities. To the extent that the support equipment and facilities are used in oil and gas producing activities, their depreciation and applicableoperating costs become exploration, development or production costs, as appropriate. Depreciation, depletion, and amortization of capitalized acquisition,exploration, and development costs are not production costs but also become part of the costs of oil and gas produced along with production (lifting) costsidentified above.“Productive well.” An exploratory, development or extension well that is not a dry well.“Proppant.” Sized particles mixed with fracturing fluid to hold fractures open after a hydraulic fracturing treatment. In addition to naturallyoccurring sand grains, man-made or specially engineered proppants, such as resin-coated sand or high-strength ceramic materials like sintered bauxite, mayalso be used. Proppant materials are carefully sorted for size and sphericity to provide an efficient conduit for production of fluid from the reservoir to thewellbore.“Proved developed reserves.” Proved reserves that can be expected to be recovered through existing wells with existing equipment and operatingmethods or in which the cost of the required equipment is relatively minor compared to the cost of a new well.“Proved reserves.” Those quantities of oil and gas which, by analysis of geoscience and engineering data, can be estimated with reasonablecertainty to be economically producible—from a given date forward, from known reservoirs and under existing economic conditions, operating methods andgovernment regulations—prior to the time at which contracts providing the right to operate expire, unless evidence indicates that renewal is reasonablycertain, regardless of whether deterministic or probabilistic methods are used for the estimation. The project to extract the hydrocarbons must havecommenced, or the operator must be reasonably certain that it will commence the project, within a reasonable time.8 Table of Contents(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 containeconomically 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 wellpenetration unless geoscience, engineering, or performance data and reliable technology establishes a lower contact with reasonable certainty.(iii)Where direct observation from well penetrations has defined a highest known oil (HKO) elevation and the potential exists for an associated gascap, proved oil reserves may be assigned in the structurally higher potions of the reservoir only if geoscience, engineering, or performance dataand reliable technology establish the higher contact with reasonable certainty.(iv)Reserves that can be produced economically through application of improved recovery techniques (including, but not limited to, fluidinjection) 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, theoperation of an installed program in the reservoir or an analogous reservoir, or other evidence using reliable technology establishes thereasonable 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 bethe average price during the 12-month period prior to the ending date of the period covered by the report, determined as an unweightedarithmetic 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.“Proved undeveloped reserves” or “PUD.” Proved reserves that are expected to be recovered from new wells on undrilled acreage, or from existingwells where a relatively major expenditure is required for recompletion. Reserves on undrilled acreage shall be limited to those directly offsettingdevelopment spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishesreasonable certainty of economic producibility at greater distances. Undrilled locations can be classified as having undeveloped reserves only if adevelopment plan has been adopted indicating that they are scheduled to be drilled within five years, unless specific circumstances justify a longer time.Under no circumstances shall estimates for proved undeveloped reserves be attributable to any acreage for which an application of fluid injection or otherimproved recovery technique is contemplated, unless such techniques have been proved effective by actual projects in the same reservoir or an analogousreservoir, or by other evidence using reliable technology establishing reasonable certainty.“PV-10.” A non-GAAP financial measure that represents inflows from proved crude oil and natural gas reserves, less future development andproduction costs, discounted at 10% per annum to reflect timing of future cash inflows and using the twelve-month unweighted arithmetic average of thefirst-day-of-the-month commodity prices (after adjustment for differentials in location and quality) for each of the preceding twelve months. Please refer tothe footnote 2 of the Proved Reserves table in Item 1 of this Annual Report on Form 10-K for additional discussion.“Reasonable certainty.” If deterministic methods are used, reasonable certainty means a high degree of confidence that the quantities will berecovered. If probabilistic methods are used, there should be at least a 90 percent probability that the quantities actually recovered will equal or exceed theestimate. 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 ofgeoscience (geological, geophysical and geochemical) engineering, and economic data are made to estimated ultimate recovery (“EUR”) with time,reasonably certain estimated ultimate recovery is much more likely to increase or remain constant than to decrease.9 Table of Contents"Reclamation." The process to restore the land and other resources to their original state prior to the effects of oil and gas development.“Recompletion.” The process of re-entering an existing wellbore that is either producing or not producing and completing new reservoirs in anattempt to establish or increase existing production.“Reserves.” Estimated remaining quantities of oil and gas and related substances anticipated to be economically producible, as of a given date, byapplication of development projects to known accumulations. In addition, there must exist, or there must be a reasonable expectation that there will exist, thelegal right to produce or a revenue interest in the production, installed means of delivering oil and gas or related substances to market, and all permits andfinancing required to implement the project.“Reserve replacement percentage.” The sum of sales of reserves, reserve extensions and discoveries, reserve acquisitions, and reserve revisions ofprevious estimates for a specified period of time divided by production for that same period.“Reservoir.” A porous and permeable underground formation containing a natural accumulation of producible crude oil and/or natural gas that isconfined by impermeable rock or water barriers and is individual and separate from other reservoirs.“Resource play.” Drilling programs targeted at regionally distributed oil or natural gas accumulations. Successful exploitation of these reservoirs isdependent upon new technologies such as horizontal drilling and multi-stage fracture stimulation to access large rock volumes in order to produce economicquantities of oil or natural gas.“Royalty interest.” An interest in an oil and natural gas property entitling the owner to a share of oil, natural gas or NGLs produced and soldunencumbered by expenses of drilling, completing and operating of the affected well.“Sales volumes.” All volumes for which a reporting entity is entitled to proceeds, including production, net to the reporting entity’s interest andthird party production obtained from percentage-of-proceeds contracts and sold by the reporting entity.“Service well.” A service well is drilled or completed for the purpose of supporting production in an existing field. Wells in this class are drilled forthe following specific purposes: gas injection, water injection, steam injection, air injection, salt-water disposal, water supply for injection, observation, orinjection for in-situ combustion.“Spacing.” Spacing as it relates to a spacing unit is defined by the governing authority having jurisdiction to designate the size in acreage of aproductive reservoir along with the appropriate well density for the designated spacing unit size. Typical spacing for conventional wells is 40 acres for oilwells and 640 acres for gas wells.“Standard reach lateral equivalent well.” Equates to a ratio of one well to one well for a standard reach lateral well, one and half wells to one wellfor a medium reach lateral well, and two wells to one well for an extended reach lateral well.“Three stream.” The separate reporting of NGLs extracted from the natural gas stream and sold as a separate product.“Undeveloped acreage.” Those leased acres on which wells have not been drilled or completed to a point that would permit the production ofeconomic quantities of oil or gas regardless of whether such acreage contains proved reserves.“Undeveloped reserves.” Undeveloped oil and gas reserves are reserves of any category that are expected to be recovered from new wells onundrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion.

The workinginterest owners bear the exploration, development, and operating costs on either a cash, penalty, or carried basis.“Workover.” Operations on a producing well to restore or increase production.“WTI.” West Texas Intermediate index.10 Table of Contents11 Table of ContentsPART IItem 1. BusinessWhen we use the terms “Bonanza Creek,” the “Company,” “we,” “us,” or “our” we are referring to Bonanza Creek Energy, Inc. and its consolidatedsubsidiaries unless the context otherwise requires. We have included certain technical terms important to an understanding of our business under Glossary ofOil and Natural Gas Terms above. Throughout this document we make statements that may be classified as “forward-looking” Please refer to the InformationRegarding Forward-Looking Statements section above for an explanation of these types of statements.OverviewBonanza Creek is an independent energy company engaged in the acquisition, exploration, development and production of onshore oil andassociated liquids-rich natural gas in the United States. Bonanza Creek Energy, Inc. was incorporated in Delaware on December 2, 2010 and went public inDecember 2011.Our oil and liquids-weighted assets are concentrated primarily in the Wattenberg Field in Colorado and the Dorcheat Macedonia Field in southernArkansas. In addition, we own and operate oil-producing assets in the North Park Basin in Colorado and the McKamie Patton Field in southern Arkansas. TheWattenberg Field is one of the premier oil and gas resource plays in the United States benefiting from a low cost structure, strong production efficiencies,established reserves and prospective drilling opportunities, which allows for predictable production and reserve growth.Bankruptcy Proceedings under Chapter 11Restructuring Support AgreementOn December 23, 2016, the Company entered into a Restructuring Support Agreement (the “RSA”) with (i) holders of approximately 51% inaggregate principal amount of the Company’s 5.75% Senior Notes due 2023 and 6.75% Senior Notes due 2021 and (ii) NGL Energy Partners, LP and NGLCrude Logistics, LLC.The RSA contemplates, among other things, (a) the equitization of the Company’s unsecured obligations pursuant to the Plan, includingapproximately $800 million in principal amount of Senior Notes, (b) a fully backstopped rights offering for the purchase of $200 million of common stock ofreorganized Bonanza Creek Energy, Inc., and (c) the entry into a new crude oil purchase agreement between the Company and NGL Crude Logistics, LLC.Voluntary Chapter 11 Bankruptcy ProceedingsOn January 4, 2017 (the “Petition Date”), the Company and all of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntarypetitions (the “Bankruptcy Petitions,” and the cases commenced thereby, collectively, the “Chapter 11 Cases”) under chapter 11 of title 11 of the UnitedStates Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) to pursue the Debtors’Joint Prepackaged Plan of Reorganization Under Chapter 11 of the Bankruptcy Code (as amended, restated, supplemented or otherwise modified from time totime, the “Prepackaged Plan”). The Debtors are authorized to operate their businesses as debtors in possession under the jurisdiction of the Bankruptcy Courtand in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.The Bankruptcy Court has granted on a final basis all of the first day motions filed by the Debtors seeking relief that would minimize the impact ofthe Chapter 11 Cases on the Company's operations, customers and employees. As a result, the Company is not only authorized to conduct business activitiesin the ordinary course and generally pay all associated obligations for the period following the Petition Date without further Bankruptcy Court approval, butit is also currently authorized to pay and has paid, subject to certain limitations, obligations that arose prior to the Petition Date related to employee wagesand benefits, services and supplies provided by vendors in the ordinary course of business and mineral interests held by royalty holders and other partners. Ingeneral, during the pendency of the Chapter 11 Cases, all transactions outside the ordinary course of our business require the prior approval of theBankruptcy Court. As a result of the automatic stay under the Bankruptcy Code, which became effective upon the commencement of the Chapter 11 Cases,most judicial or administrative actions against the Company by its creditors to collect on or otherwise exercise rights or remedies with respect to claims thatarose before the Petition Date are stayed during the pendency of the Chapter 11 Cases.A hearing to consider confirmation of the Prepackaged Plan and approval of the Debtors’ Disclosure Statement is currently scheduled to begin onApril 3, 2017.12 Table of ContentsFor the duration of our Chapter 11 proceedings, our operations and our ability to develop and execute our business plan are subject to the risks anduncertainties associated with our Chapter 11 cases as described in Item 1A, “Risk Factors.” As a result of these risks and uncertainties, our assets, liabilities,officers and/or directors could be significantly different following the outcome of the Chapter 11 proceedings, and the description of our operations,properties and capital plans included in this Annual Report may not accurately reflect our operations, properties and capital plans following the Chapter 11process.For a further description of these matters, see Note 19 - Subsequent Events.Our Business StrategiesWe scaled back our capital expenditures to match our liquidity constraints and current commodity pricing environment. We invested $21.7 millionon capital projects in 2016 versus $404.0 million in 2015.While faced with these liquidity restraints, we have taken various steps to reduce our operating costs. During 2016, we eliminated unnecessary costsand negotiated with our primary suppliers and service providers resulting in a 33% reduction in our lease operating expenses.Our strategy is to operate a development program on contiguous acreage blocks that have high working interest, allowing us to control the pace andmagnitude of our future capital expenditures and provide efficient resource development through multi-well pads and centralized facilities. Upon emergencefrom bankruptcy, management currently intends to operate a one-rig program in 2017 to drill 61 operated standard reach lateral equivalent wells that arewithin close proximity to the Company's existing infrastructure to keep costs down.In 2016, we successfully drilled ten and completed 13 gross productive operated wells and participated in drilling seven and completing eight grossproductive non-operated wells. We had six gross operated wells and seven gross non-operated wells drilled and awaiting completion as of December 31,2016. Our sales volumes during the fourth quarter of 2016 were 18,239 Boe/d, a 36% decrease over the comparable period in 2015.The following tables summarize our estimated proved reserves, PV-10 reserve value, sales volumes, and projected capital spend as of December 31,2016: Natural Crude Natural Gas Total Oil Gas Liquids ProvedEstimated Proved Reserves (MBbls) (MMcf) (MBbls) (MBoe)Developed Rocky Mountain 18,735 62,097 8,792 37,877 Mid-Continent 7,578 23,875 1,159 12,716 26,313 85,972 9,951 50,593Undeveloped Rocky Mountain 23,783 52,073 7,596 40,057 Mid-Continent — — — — 23,783 52,073 7,596 40,057Total Proved 50,096 138,045 17,547 90,65013 Table of Contents Sales Volumes for the Year Ended Net Proved Estimated Proved Reserves at December 31, Undeveloped December 31, 2016(1) 2016 Drilling Average Net Projected Locations Total Daily Sales 2017 Capital as of Proved % of % Proved PV-10 Volumes % of Expenditures December 31, (MBoe) Total Developed ($ in MM)(2) (Boe/d) Total ($ in millions) 2016Rocky Mountain 77,934 86% 49% $201.4 17,619 81% $160-175 163.4Mid-Continent(3) 12,716 14% 100% 75.5 4,063 19% 3-5 —Total 90,650 100% 56% $276.9 21,682 100% $163-180 163.4_____________________(1)Proved reserves and related future net revenue and PV-10 were calculated using prices equal to the twelve-month unweighted arithmetic average of thefirst-day-of-the-month commodity prices for each of the preceding twelve months, which were $42.75 per Bbl WTI and $2.48 per MMBtu HH.Adjustments were then made for location, grade, transportation, gravity, and Btu content, which resulted in a decrease of $4.33 per Bbl of crude oil and adecrease of $0.41 per MMBtu of natural gas.(2)PV-10 is a non-GAAP financial measure and represents the present value of estimated future cash inflows from proved crude oil, natural gas, and naturalgas liquid reserves, less future development and production costs, discounted at 10% per annum to reflect timing of future cash inflows using the twelve-month unweighted arithmetic average of the first-day-of-the-month commodity prices, after adjustment for differentials in location and quality, for eachof the preceding twelve months. We believe that PV-10 provides useful information to investors as it is widely used by professional analysts andsophisticated investors when evaluating oil and gas companies. We believe that PV-10 is relevant and useful for evaluating the relative monetarysignificance of our reserves. Professional analysts and sophisticated investors may utilize the measure as a basis for comparison of the relative size andvalue of our reserves to other companies’ reserves. Because there are many unique factors that can impact an individual company when estimating theamount of future income taxes to be paid, we believe the use of a pre-tax measure is valuable in evaluating the Company and our reserves. PV-10 is notintended to represent the current market value of our estimated reserves. PV-10 differs from Standardized Measure of Discounted Future Net Cash Flows(“Standardized Measure”) because it does not include the effect of future income taxes. Please refer to the Reconciliation of PV-10 to StandardizedMeasure presented in the “Reserves” subsection of Item 1 below.(3)Mid-Continent sales volumes were 4,063 Boe/d for 2016, which is comprised of 3,653 Boe/d of production net to our interest and 410 Boe/d salesvolumes from our percentage-of-proceeds contracts.Our OperationsOur operations are mainly focused in the Wattenberg Field in the Rocky Mountain region and in the Dorcheat Macedonia Field in the Mid-Continent region.Rocky Mountain RegionThe two main areas in which we operate in the Rocky Mountain region are the Wattenberg Field in Weld County, Colorado and the North ParkBasin in Jackson County, Colorado. As of December 31, 2016, our estimated proved reserves in the Rocky Mountain region were 77,934 MBoe, whichrepresented 86% of our total estimated proved reserves and contributed 17,619 Boe/d, or 81%, of sales volumes during 2016.Wattenberg Field - Weld County, Colorado. Our operations are in the oil and liquids-weighted extension area of the Wattenberg Field targeting theNiobrara and Codell formations. As of December 31, 2016, our Wattenberg position consisted of approximately 96,000 gross (67,000 net) acres.The Wattenberg Field is now primarily developed for the Niobrara and Codell formations using horizontal drilling and multi-stage fracturestimulation techniques. We believe the Niobrara B and C benches have been fully delineated on our legacy acreage, while the Codell formation has beendelineated on our western acreage. Our northern acreage is in the early stages of delineation.Our estimated proved reserves at December 31, 2016 in the Wattenberg Field were 77,730 MBoe. As of December 31, 2016, we had a total of 628gross producing wells, of which 406 were horizontal wells, and our sales volumes during 2016 were14 Table of Contents17,543 Boe/d. Our sales volumes for the fourth quarter of 2016 were 14,508 Boe/d. As of December 31, 2016, our working interest for all producing wellsaveraged approximately 89% and our net revenue interest was approximately 73%.We drilled and participated in drilling 18 gross (9.5 net) standard reach lateral equivalent wells and one vertical well in 2016 in the WattenbergField. In 2016, we completed and participated in completing a total of 27 gross (14.0 net) standard reach lateral equivalent wells and one vertical well in theWattenberg Field. As of December 31, 2016, we have an identified drilling inventory of approximately 210 gross (163.4 net) proved undeveloped (“PUD”)drilling locations (226 gross standard reach lateral equivalents) on our acreage.During the year, in the Niobrara benches, we drilled two extended reach lateral operated wells, six standard reach lateral operated wells and onevertical operated well and we completed four medium reach lateral operated wells, eight standard reach lateral operated wells and one vertical operated well.In addition, we drilled one Codell standard reach lateral operated well. We also participated in the drilling of six standard reach lateral wells (0.01 net) andthe completion of five extended reach lateral wells (0.5 net) in the Niobrara formation.Upon emergence from bankruptcy, based on the plan provided to signatories to the RSA, management currently intends to operate a one-rig programwith an intermittent second rig to satisfy leasehold obligations within the Wattenberg Field in 2017. The capital requirements expected for this programrange from $160.0 million to $175.0 million for the time period from May to December 2017. This program contemplates drilling and completing 61 grossoperated standard reach lateral equivalent wells, participating in economic non-operated wells that are proposed and investing a modest amount oninfrastructure. The capital budget is dependent on emergence from bankruptcy and approval from a newly appointed board and could vary, given, forexample, that we observed evidence of an increase in drilling and completion costs since year end.North Park Basin - Jackson County, Colorado. We control approximately 19,000 gross (15,000 net) acres in the North Park Basin in JacksonCounty, Colorado, all prospective for the Niobrara oil shale. We operate the North and South McCallum Fields, which currently produce light oil, which istrucked to market.In the North Park Basin, our estimated proved reserves as of December 31, 2016 were approximately 204 MBoe, consisting of 100% crude oil, andour sales volumes during 2016 were 76 Boe/d. Our sales volumes in the North Park Basin for the fourth quarter of 2016 were 72 Boe/d. There were no wellsdrilled during 2016 in the North Park Basin.None of our 2017 capital budget is assigned to the North Park Basin.Mid-Continent RegionIn southern Arkansas, we target the oil-rich Cotton Valley sands in the Dorcheat Macedonia and McKamie Patton Fields. As of December 31, 2016,our estimated proved reserves in the Mid-Continent region were 12,716 MBoe, which is inclusive of a reduction of 7.8 MMBoe of PUDs due to an inabilityto demonstrate a commitment to deploy capital into this program during 2016, 69% of which were oil and NGLs and 100% of which were proved developed.We currently have 308 gross producing vertical wells. During 2016, no wells were drilled in the Mid-Continent region; however, the Company recompleted32 wells in the Cotton Valley formation. We achieved a sales volume rate for 2016 of 4,063 Boe/d, of which 70% was from oil and NGLs, and a sales volumerate for the fourth quarter of 2016 of 3,658 Boe/d. We have a 2017 capital budget of $3.0 million to $5.0 million for the Mid-Continent region.Dorcheat Macedonia. In the Dorcheat Macedonia Field, we average an approximate 89% working interest and an approximate 74% net revenueinterest on all producing wells. The majority of our acreage is held by unitization or production. Our production during 2016 was approximately 3,485 Boe/d(3,895 Boe/d sales volumes). During the fourth quarter of 2016, our production was 3,173 Boe/d (3,583 Boe/d sales volumes). Our proved reserves in thisfield are approximately 11,604 MBoe. Due to the Company having no plans to drill within the Mid-Continent region, we wrote off all 96 PUD locations thatwere previously recorded.Other Mid-Continent. We own additional interests in the McKamie Patton Field in the Mid-Continent region near the Dorcheat Macedonia Field. Asof December 31, 2016, our estimated proved reserves were approximately 1,112 MBoe, and sales volumes during 2016 were approximately 168 Boe/d.During the fourth quarter of 2016, our production was 76 Boe/d.Gas Processing Facilities. Our Mid-Continent gas processing facilities are located in Lafayette and Columbia counties in Arkansas and arestrategically located to serve our production in the region. Our McKamie Gas Plant has been idle since 2015 and our Dorcheat Macedonia Field Gas Plant hasa current capacity of 24 MMcf/d with 54,000 gallons per day of15 Table of Contentsassociated NGL capacity. Our ownership of these facilities and related gathering pipeline provides us with the benefit of controlling processing andcompression of our natural gas production.ReservesEstimated Proved ReservesThe summary data with respect to our estimated proved reserves presented below has been prepared in accordance with rules and regulations of theSecurities and Exchange Commission (the “SEC”) applicable to companies involved in oil and natural gas producing activities. Our reserve estimates do notinclude probable or possible reserves, categories which SEC rules do permit us to disclose in public reports. Our estimated proved reserves for the years endedDecember 31, 2016, 2015 and 2014 were determined using the preceding twelve month unweighted arithmetic average of the first-day-of-the-month prices.For a definition of proved reserves under the SEC rules, please see the Glossary of Oil and Natural Gas Terms included in the beginning of this report.Reserve estimates are inherently imprecise and estimates for undeveloped properties are more imprecise than reserve estimates for producing oil andgas properties. Accordingly, these estimates are expected to change as new information becomes available. The PV-10 values shown in the following tableare not intended to represent the current market value of our estimated proved reserves. Neither prices nor costs have been escalated. The actual quantitiesand present values of our estimated proved reserves may vary from what we have estimated.The table below summarizes our estimated proved reserves as of December 31, 2016, 2015 and 2014 for each of the regions and currently producingfields in which we operate. The proved reserve estimates as of December 31, 2016, 2015 and 2014 are based on reports prepared by our internal corporatereservoir engineering group, of which 100% were audited by Netherland, Sewell & Associates, Inc. (“NSAI”), our third-party independent reserve engineers.For more information regarding our independent reserve engineers, please see Independent Reserve Engineers below.

Adjustments were made for location and grade.(2)Determined using the ratio of 6 Mcf of natural gas to one Bbl of crude oil.Proved developed oil and gas reserves are reserves that can be expected to be recovered through existing wells with existing equipment andoperating methods. Proved undeveloped oil and gas reserves are reserves that are expected to be recovered from new wells on undrilled acreage, or fromexisting wells where a relatively major expenditure is required for completion. Proved undeveloped reserves on undrilled acreage are limited to those directlyoffsetting development spacing areas that are reasonably certain of production when drilled, unless evidence using reliable technology exists that establishesreasonable certainty of economic productivity at greater distances.Proved undeveloped locations in our December 31, 2016 reserve report are included in our development plan and are scheduled to be drilled withinfive years from their initial proved booking date. The Company’s management evaluated the proved undeveloped drilling plan using NYMEX strip prices,the liquidation model for general and administrative costs, the cash from the rights offering as contemplated in the RSA and the cash flows from existingproperties. The Company's PUD conversion was 3%, 16% and 21% for the years ended December 31, 2016, 2015 and 2014, respectively. The Companysuspended all drilling and completion activities after the first quarter of 2016; as such, 2016 was deemed an anomaly to the Company's PUD conversionstandards. The Company currently intends to operate a one-rig program upon emergence from bankruptcy and fully anticipates being able to convert theremaining Rocky Mountain region PUDs within the allotted five-year window assuming drilling and completion activities resumes in the second quarter of2017. The Company wrote off 100% of its PUDs within the Mid-Continent region as there are no current funded commitments to drill within the region as ofDecember 31, 2016. The reliable technologies used to establish our proved reserves are a combination of pressure performance, geologic mapping, offsetproductivity, electric logs, and production data.Estimated proved reserves at December 31, 2016 were 90.7 MMBoe, a 10% decrease from estimated proved reserves of 101.3 MMBoe atDecember 31, 2015. Approximately 86% of our December 31, 2016 proved reserves are attributed to the Rocky Mountain region, and 99.7% of the RockyMountain proved reserves in turn are attributed to the Wattenberg Field. The17 Table of Contentsnet decrease in our reserves of 10.6 MMBoe is the result of 2016 production of 7.8 MMBoe coupled with writing off 16.4 MMBoe of PUDs and 1.9 MMBoeof other engineering revisions offset by additions in extensions, discoveries and infills of 10.8 MMBoe and net positive cost revisions (reserve prices lessdrilling and completion costs and LOE) of 4.7 MMBoe.The 10.8 MMBoe addition in extensions, discoveries and infills is primarily the result of completing five operated and six non-operated unprovedhorizontal locations in the Niobrara formation that were in progress at year-end 2015, and drilling and completing three non-operated unproved horizontalwells and one operated unproved vertical well in the Niobrara formation in the Wattenberg Field during 2016, and adding 42 infill PUD locations nearexisting central processing facilities (“CPFs”). These infill locations offset PDP wells drilled prior to 2016. In the engineering revision category, 38 provedundeveloped locations were written off because they were not in close proximity to existing CPFs or CPFs that were planned to be built in 2016 but were notdue to liquidity contraints. New drilling in 2017 will begin around the existing CPF's, as they can be hooked up immediately upon completion. For the yearending December 31, 2016, approximately 85% of the Company's development drilling in the Wattenberg Field was in the Niobrara formation, 15% in theCodell. The majority of the proved undeveloped locations are spaced on 80 acres within each bench. Thirty-six of the Niobrara locations are planned to bedrilled on 80/40 geometry. An 80/40 well is where the locations in one formation are spaced on 80 acre units, while the lower locations, also spaced 80 acresapart, are offset 40 acres from the bench above.Total Company positive engineering revisions as of December 31, 2016, were 28,625 Mboe, of which 32,899 Mboe were related to positive reservechanges in the Wattenberg Field and 4,416 Mboe were related to negative reserve changes in the Dorcheat Macedonia Field. The overall positiveengineering revision is offset by a negative pricing revision of 39,222 Mboe in the Wattenberg Field and 2,778 Mboe in the Dorcheat Macedonia Field. Thenegative pricing revision of 42,143 Mboe for the Company resulted from a decrease in average commodity price from $50.28 per Bbl WTI and $2.59 perMMBTU HH for the year ended December 31, 2015 to $42.75 per Bbl WTI and $2.48 per MMBTU HH for the year ended December 31, 2016. The majorityof the positive revisions in the Wattenberg Field resulted from a combination of decreased drilling and completion costs and a continued decrease in the LOEwhich had begun in 2015. The total proved undeveloped location count in the Wattenberg Field is 210 (226 standard reach lateral equivalents) and was 204as of December 31, 2015. Our five-year plans include the drilling of these proved undeveloped locations. The 2017 drilling program included in the year-end2016 reserves is a one-rig program estimated to convert 25% of our year end 2016 proved undeveloped reserves in the Wattenberg Field. There are ninehorizontal proved undeveloped locations in the Wattenberg Field that would expire in 2017 if they are not drilled this year. If we begin drilling in the secondquarter of 2017, operate a single-rig program in 2017 and 2018, add one additional rig for six months in 2019 and revert to a one-rig program thereafter, allremaining PUD locations will be developed within their five-year windows. The PUD locations in the Dorcheat Macedonia Field were all demoted becausethey would not be drilled within their five-year window under the current drilling plan, which is focused on the Wattenberg Field.Total Company positive engineering revisions as of December 31, 2015, were 37,174 Mboe, of which 30,086 Mboe (81%) related to reserve changesin the Wattenberg Field. This positive engineering revision was offset by a negative pricing revision of 21,417 Mboe in the Wattenberg Field. The majorityof the positive revisions in the Wattenberg Field resulted from a combination of decreased drilling and completion costs, $3.0 million per standard reachlateral well as of December 31, 2015 compared to $4.2 million at December 31, 2014, a 29% decrease, and an increase in productivity from horizontal proveddeveloped producing wells, which increased the offsetting proved undeveloped reserves. The increase in PDP reserves was primarily attributed to theinstallation of infrastructure in the east side of our Wattenberg Field acreage, which removed the producing constraint that inhibited productivity over theprior two years of development in that area. Another significant contribution to the positive reserve revision in the Wattenberg Field results from a contractchange as of January 1, 2015, which gives our Company ownership of the natural gas liquids from our gas production. This conversion from two-stream (wetgas and oil) to three-stream (dry gas, natural gas liquids and oil) added 8,560 Mboe to our proved reserves as of December 31, 2015. With the addition of 45horizontal proved undeveloped locations in the Wattenberg Field to the proved reserves at December 31, 2015, the total proved undeveloped location countwas 204 (220 standard reach lateral equivalents) and was 226 as of December 31, 2014. A negative pricing revision of 28,810 Mboe for the Company resultedfrom a decrease in average commodity price from $94.99 per Bbl WTI and $4.35 per MMBTU HH for the year ended December 31, 2014 to $50.28 per BblWTI and $2.59 per MMBTU HH for the year ended December 31, 2015.Estimated proved reserves at December 31, 2014 were 89.5 MMBoe, a 28% increase from estimated proved reserves of 69.8 MMBoe at December31, 2013. The net increase in reserves of 19.7 MMBoe was the result of additions in extensions and discoveries of 20.2 MMBoe, primarily due to thedevelopment of the Niobrara B and C benches and the Codell formations in the Wattenberg Field, coupled with a net positive revision of 7.1 MMBoe(engineering and pricing) and net acquisitions (acquisitions less divestitures) of 0.8 MMBoe offset by 8.4 MMBoe in production. The addition in extensionand discoveries was primarily the result of drilling and completing 99 unproved horizontal locations (including 12 non-operated) in the Niobrara and theCodell formations in the Wattenberg Field during 2014 and the addition of 37 new horizontal proved undeveloped locations directly offsetting new wellsbrought online in 2014. As of December 31, 2014, approximately 70% of18 Table of Contentsour horizontal development in the Wattenberg Field was in the Niobrara B formation, the majority of which was on 80-acre spacing. The net positiveengineering revision was primarily the result of adding new Niobrara B proved undeveloped locations on 80-acre spacing, directly offsetting economicproved producing Niobrara B wells drilled prior to 2014, diagonal offsets to economic Niobrara B proved producing wells and a relatively small number oflocations greater than one offset to economic Niobrara B proved producing wells but within developed areas and surrounded by Niobrara B provedproducing wells. A total of 119 horizontal proved undeveloped locations were added to the proved reserves at December 31, 2014 of which 86 (72%) weredirect offsets to economic proved producing wells (drilled in 2014 or prior to 2014), 21 (18%) were direct offsets in a diagonal pattern to economic provedproducing wells and 12 (10%) were greater than one offset from economic proved producing wells. The reasonable certainty of the reserves associated withthe latter two categories of proved undeveloped locations was based on analysis of the immediate surrounding productivity of the Niobrara B bench anddetailed geologic mapping. All Niobrara proved undeveloped locations were spaced on 80 acres. The positive engineering revision was offset by a smallnegative performance revision of approximately 540 MBoe. A negative pricing revision of 0.25 MMBoe resulted from a decrease in average commodityprice from $96.91 per Bbl WTI and $3.67 per MMBTU HH for the year ended December 31, 2013 to $94.99 per Bbl WTI and $4.35 per MMBTU HH for theyear ended December 31, 2014.Reconciliation of PV-10 to Standardized MeasurePV-10 is derived from the Standardized Measure, which is the most directly comparable GAAP financial measure. PV-10 is a computation of theStandardized Measure on a pre-tax basis. PV-10 is equal to the Standardized Measure at the applicable date, before deducting future income taxes,discounted at 10%. We believe that the presentation of PV-10 is relevant and useful to investors because it presents the discounted future net cash flowsattributable to our estimated net proved reserves prior to taking into account future corporate income taxes, and it is a useful measure for evaluating therelative monetary significance of our oil and natural gas properties. Further, investors may utilize the measure as a basis for comparison of the relative sizeand value of our reserves to other companies. We use this measure when assessing the potential return on investment related to our oil and natural gasproperties. PV-10, however, is not a substitute for the Standardized Measure. Neither our PV-10 measure or the Standardized Measure purport to present thefair value of our oil and natural gas reserves.The following table provides a reconciliation of PV-10 to Standardized Measure at December 31, 2016, 2015 and 2014: December 31, 2016 2015 2014 (in millions)PV-10 $276.9 $327.8 $1,340.5Present value of future income taxes discounted at 10%(1) — — (233.1)Standardized Measure $276.9 $327.8 $1,107.4____________________________(1) The tax basis of our oil and gas properties as of December 31, 2016 and 2015 provides more tax deduction than income generated from our oil and gasproperties when the reserve estimates were prepared using $42.75 per Bbl WTI and $2.48 per MMBTU HH and $50.28 per Bbl WTI and $2.59 per MMBTUHH, respectively.Proved Undeveloped Reserves Net Reserves, MBoe At December 31, 2016 2015 2014Beginning of year 49,184 43,246 37,603Converted to proved developed (1,352) (6,994) (7,791)Additions from capital program — 2,308 5,596Acquisitions — 1,541 —Revisions (7,775) 9,083 7,838End of year 40,057 49,184 43,246At December 31, 2016, our proved undeveloped reserves were 40,057 MBoe, all of which are scheduled to be drilled within five years of their initialproved booking date. During 2016, the Company converted 3% of its proved undeveloped19 Table of Contentsreserves (seven gross wells representing net reserves of 1,352 MBoe) at a cost of $16.2 million. Our 2016 capital program was shut down after the first quarter,and no proved undeveloped locations were added as a result of drilling. The net decrease in our PUD reserves was mainly the result of demoting 7.8 MMBoeof PUDs in the Mid-Continent region, as drilling is now focused entirely on the Wattenberg Field. Thirty-eight Wattenberg proved undeveloped locationsthat were not in areas with existing CPF's were demoted and were replaced with 42 infill proved undeveloped locations that are near existing CPFs. Currentplans are to begin drilling the new and existing proved undeveloped locations within close proximity to existing CPFs upon emergence from bankruptcy.At December 31, 2015, our proved undeveloped reserves were 49,184 MBoe, all of which were scheduled to be drilled within five years of theirinitial proved booking date. During 2015, the Company converted 16% of its proved undeveloped reserves (52 gross wells representing net reserves of 6,994MBoe) at a cost of $121.0 million. Executing our 2015 capital program resulted in the addition of 2,308 MBoe (17 gross wells) in proved undevelopedreserves in the Wattenberg Field. A small acquisition within the field limits of the Dorcheat Macedonia Field added 14 gross proved undeveloped locationsand 1,541 MBoe to our reserves. The positive engineering revision of 9,083 MBoe was primarily the result of adding 28 gross new proved undevelopedlocations in the Wattenberg Field on 80-acre spacing, the majority directly offsetting economic proved producing wells drilled prior to 2015, and an increasein proved undeveloped reserves in the eastern portion of the Wattenberg Field resulting from increased productivity due to the installation of infrastructure,which eliminated a production constraint thereby allowing productivity to rise, proved developed reserves to increase, and associated proved undevelopedreserves to increase by an estimated 3.0 MMBoe.At December 31, 2014, our proved undeveloped reserves were 43,246 MBoe, all of which were scheduled to be drilled within five years of theirinitial proved booking date. During 2014, the Company converted 21% of its proved undeveloped reserves (58 gross wells representing net reserves of 7,791MBoe) at a cost of $116.9 million. Executing our 2014 capital program resulted in the addition of 5,596 MBoe (45 gross wells) in proved undevelopedreserves. The positive engineering revision of 7,838 MBoe was primarily the result of adding 49 new proved undeveloped locations in the Wattenberg Fieldon 80-acre spacing, directly offsetting economic proved producing wells drilled prior to 2014, 21 diagonal offsets to economic proved producing wells and12 gross proved undeveloped locations positioned greater than one offset to economic proved producing wells but within developed areas and surroundedby proved producing wells. Also included in the revision category was the removal from proved undeveloped locations of 15 horizontal locations in theWattenberg Field that were no longer spaced on 80 acres following the 2014 capital drilling program and all of the vertical proved undeveloped locations inthe Wattenberg Field that have been replaced by horizontal wells or are expected to be replaced in the future. Proved undeveloped locations remaining in thecategory from December 31, 2013 received a downward revision of 214 Mboe.Internal controls over reserves estimation processOur policies regarding internal controls over the recording of reserves estimates require reserves to be in compliance with SEC definitions andguidance and prepared in accordance with Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by theSociety of Petroleum Engineers. The Company’s Reserves Committee reviews significant reserve changes on an annual basis and our third-party independentreserve engineers, NSAI, is engaged by and has direct access to the Reserves Committee. NSAI audited 100% of our estimated proved reserves atDecember 31, 2016, 2015 and 2014.Responsibility for compliance in reserves estimation is delegated to our internal corporate reservoir engineering group managed by John E.Vorwerk. Mr. Vorwerk is our Corporate Reserves Manager. Mr. Vorwerk attended the Colorado School of Mines and graduated in 1976 with a Bachelor ofScience degree in Geological Engineering. He also received a Master of Science degree in Mineral Economics from the Colorado School of Mines in 1991.Mr. Vorwerk has been in the petroleum industry for 41 years, and has been a Registered Professional Engineer since 1981. He has been directly involved inevaluations and the estimation of reserves and resources, and has worked in the corporate reserves function for over 21 years. He has been employed atBonanza for three years, and has been the Corporate Reserves Manager for the past two and a half years. Collectively with Mr. Vorwerk, our internal corporatereservoir engineering group has over 85 years of industry experience.Our technical team works with our banking syndicate members for a valuation of our reserves by the banks in our lending group and their engineersin determining the borrowing base under our revolving credit facility.Independent Reserve EngineersThe reserves estimates for the years ended December 31, 2016, 2015 and 2014 shown herein have been independently audited by NSAI, a worldwideleader of petroleum property analysis for industry and financial organizations and government agencies. NSAI was founded in 1961 and performs consultingpetroleum engineering services under Texas Board of Professional Engineers Registration No. F-2699. Within NSAI, the technical persons primarilyresponsible for auditing the20 Table of Contentsestimates set forth in the NSAI audit letter incorporated herein are Mr. Dan Paul Smith and Mr. John G. Hattner. Mr. Smith, a Licensed Professional Engineerin the State of Texas (No. 49093), has been practicing consulting petroleum engineering at NSAI since 1980 and has over 7 years of prior industryexperience. He graduated from Mississippi State University in 1973 with a Bachelor of Science Degree in Petroleum Engineering. Mr. Hattner, a LicensedProfessional Geoscientist in the State of Texas, Geology (No. 559), has been practicing consulting petroleum geoscience at NSAI since 1991, and has over 11years of prior industry experience.

Both technical principals meet or exceed the education, training, and experience requirements set forth in the StandardsPertaining to the Estimating and Auditing of Oil and Gas Reserves Information promulgated by the Society of Petroleum Engineers; both are proficient injudiciously applying industry standard practices to engineering and geoscience evaluations as well as applying SEC and other industry reserves definitionsand guidelines.Production, Revenues and Price HistoryThe recent collapse in oil prices was among the most severe on record. The daily NYMEX WTI oil spot price went from a high of $107.62 per Bbl in2014 to a low of $26.19 per Bbl in 2016. The drop in crude oil pricing was due in large part to increased production levels, crude oil inventories and recessedglobal economic growth. Oil prices are also impacted by real or perceived geopolitical risks in oil producing regions, the relative strength of the U.S. dollar,weather and the global economy. Gas prices were under downward pressure during 2015 and the first half of 2016 due to excess supply leading to higherlevels of gas in storage when compared to the five-year average. These depressed oil prices lead to dramatic cuts in the exploration and production budgetswhich incrementally reduced oil supply, and have helped prices rebound off of the lows experienced in the first quarter of 2016. With better pricing in thebeginning of 2017, compared to 2016, we expect increased industry activity which could moderate the magnitude of price increases throughout the year.Sensitivity AnalysisIf oil and natural gas SEC prices declined by 10%, our proved reserve volumes would decrease by 8% and our PV-10 value as of December 31, 2016would decrease by approximately 42% or $116.2 million. The PV-10 value of our Rocky Mountain region, primarily our Wattenberg assets, would decreaseby 48% or $97.5 million.The Company incurred an immaterial impairment of proved properties of $10.0 million on its Mid-Continent assets resulting from a received bidwhile the assets were held for sale, but these assets are no longer held for sale as of December 31, 2016. We do not anticipate triggering additionalimpairments in 2017 when analyzing price changes only. However, upon emergence from bankruptcy, there could be additional impairments due to theassigned enterprise value of the Company.ProductionThe following table sets forth information regarding oil, natural gas, and natural gas liquids production, sales prices, and production costs for theperiods indicated.

There was no oil transportation revenues for the year ended December 31, 2014.(5)Natural gas sales includes $1.5 million and $0.8 million of gas gathering revenues from third parties, which do not have associated sales volumes, for theyears ended December 31, 2016 and 2015, respectively. There was no gas gathering transportation revenues for the year ended December 31, 2014.Principal CustomersThree of our customers, Silo Energy, LLC, Lion Oil Trading & Transportation, Inc., and Duke Energy Field Services comprised 50%, 18%, and 14%,respectively, of our total revenue for the year ended December 31, 2016. No other single non-affiliated customer accounted for 10% or more of our oil andnatural gas sales in 2016. We believe the loss of any one customer would not have a material effect on our financial position or results of operations becausethere are numerous potential customers for our production.22 Table of ContentsDelivery CommitmentsWe have entered into two purchase agreements to deliver a fixed determinable quantity of crude oil within the Wattenberg Field. The first agreementtook effect during the second quarter of 2015 for 12,580 gross barrels per day over an initial five-year term. The second agreement took effect during thefourth quarter of 2016 for 15,000 gross barrels per day over an initial seven-year term. The aggregate financial commitment fee for both agreements isapproximately $437.1 million at December 31, 2016. While the volume commitment may be met with Company volumes or third-party volumes, theCompany has been required to make periodic deficiency payments for current shortfalls in delivering the minimum monthly volume commitments.Amending one of these agreements and terminating the other is contemplated within our bankruptcy case. Please refer to Note 8 - Commitments andContingencies for additional discussion.Productive WellsThe following table sets forth the number of producing oil and natural gas wells in which we owned a working interest at December 31, 2016.

We focus primarily on the core fields of development where reserve bookings are prevalent. Decisions to let leasehold expiregenerally relate to areas out of our core fields of development or do not pose material impacts to development plans or reserves.23 Table of ContentsThe following table sets forth the number of net undeveloped acres by area as of December 31, 2016 that will expire over the next three years unlessproduction is established within the spacing units covering the acreage or the applicable leases are extended prior to the expiration dates: Expiring 2017 Expiring 2018 Expiring 2019 Gross Net Gross Net Gross NetRocky Mountain 6,241 4,597 7,047 4,071 1,659 444Mid-Continent 260 212 42 8 40 9 Total 6,501 4,809 7,089 4,079 1,699 453Drilling ActivityThe following table describes the exploratory and development wells we drilled and completed during the years ended December 31, 2016, 2015and 2014.

The Wattenberg Field capital budget ranges from $160.0 million to $175.0million to drill 23 operated standard reach lateral wells and 19 operated extended reach lateral wells. The Wattenberg program will also consist of a modestinfrastructure investment as well as participation in economic non-operated wells. The remaining capital budget of $3.0 million to $5.0 million is slated forrecompletions within the Mid-Continent region. Actual capital expenditures could vary significantly based on, among other24 Table of Contentsthings, emergence from bankruptcy, approval by the newly appointed board, market conditions, commodity prices, the final amount of the rights offeringeffectuated pursuant to the RSA, and changes in the borrowing base under our revolving credit facility. We have observed evidence of an increase in drillingand completion costs since year-end, which would impact actual capital expenditures.Title to PropertiesOur properties are subject to customary royalty interests, overriding royalty interests, obligations incident to operating agreements, liens for currenttaxes and other industry‑related constraints, including leasehold restrictions. We do not believe that any of these burdens materially interfere with our use ofthe properties in the operation of our business. We believe that we have satisfactory title to or rights in all of our producing properties. We undergo thoroughtitle review and receive title opinions from legal counsel before we commence drilling operations, subject to the availability and examination of accuratetitle records. Although in certain cases, title to our properties is subject to interpretation of multiple conveyances, deeds, reservations, and other constraints,we believe that none of these will materially detract from the value of our properties or from our interest therein or will materially interfere with the operationof our business.CompetitionThe oil and natural gas industry is highly competitive and we compete with a substantial number of other companies that have greater resources.Many of these companies explore for, produce and market oil and natural gas, carry on refining operations and market the resultant products on a worldwidebasis. The primary areas in which we encounter substantial competition are in locating and acquiring desirable leasehold acreage for our drilling anddevelopment operations, locating and acquiring attractive producing oil and gas properties, attracting and retaining qualified personnel, and obtainingtransportation for the oil and gas we produce in certain regions. There is also competition between producers of oil and gas and other industries producingalternative energy and fuel. Furthermore, competitive conditions may be substantially affected by various forms of energy legislation and/or regulationconsidered from time to time by federal, state and local governments; however, it is not possible to predict the nature of any such legislation or regulationthat may ultimately be adopted or its effects upon our future operations. Such laws and regulations may, however, substantially increase the costs ofexploring for, developing or producing gas and oil and may prevent or delay the commencement or continuation of a given operation. The effect of theserisks cannot be accurately predicted.Further, oil prices and natural gas prices do not necessarily fluctuate in direct relationship to each other. Because approximately 75% of ourestimated proved reserves as of December 31, 2016 were oil and natural gas liquids reserves, our financial results are more sensitive to movements in oilprices. During the year ended December 31, 2016, the daily NYMEX WTI oil spot price ranged from a high of $54.01 per Bbl to a low of $26.19 per Bbl, andthe NYMEX natural gas HH spot price ranged from a high of $3.80 per MMBtu to a low of $1.49 per MMBtu.Insurance MattersAs is common in the oil and gas industry, we will not insure fully against all risks associated with our business either because such insurance is notavailable or because premium costs are considered prohibitive. A loss not fully covered by insurance could have a material adverse effect on our financialposition, results of operations or cash flows.Regulation of the Oil and Natural Gas IndustryOur operations are substantially affected by federal, state and local laws and regulations. In particular, oil and natural gas production and relatedoperations are, or have been, subject to price controls, taxes and numerous other laws and regulations. All of the jurisdictions in which we own or operateproperties for oil and natural gas production have statutory provisions regulating the exploration for and production of oil and natural gas, includingprovisions related to permits for the drilling of wells, bonding requirements to drill or operate wells, the location of wells, the method of drilling and casingwells, the surface use and restoration of properties upon which wells are drilled, sourcing and disposal of water used in the drilling and completion process,and the abandonment of wells. Our operations are also subject to various conservation laws and regulations. These include regulation of the size of drillingand spacing units or proration units, the number of wells which may be drilled in an area, and the unitization or pooling of oil and natural gas wells, andregulations that generally prohibit the venting or flaring of natural gas and that impose certain requirements regarding the ratability or fair apportionment ofproduction from fields and individual wells.Failure to comply with applicable laws and regulations can result in substantial penalties. Our competitors in the oil and natural gas industry aresubject to the same regulatory requirements and restrictions that affect our operations. The regulatory burden on the industry can increase the cost of doingbusiness and negatively affect profitability. Because such laws25 Table of Contentsand regulations are frequently amended through various rulemakings, it is difficult, and we are often unable to predict the future costs or impact ofcompliance. Additional proposals and proceedings that affect the natural gas industry are regularly considered by Congress, the states and variousmunicipalities, the Federal Energy Regulatory Commission (“FERC”), and the courts. We cannot predict when or whether any such proposals or proceedingsmay become effective and if the outcomes will negatively affect our operations.We believe that continued substantial compliance with existing requirements will not have a material adverse effect on our financial position, cashflows or results of operations. However, current regulatory requirements may change, currently unforeseen incidents may occur or past non-compliance withlaws or regulations may be discovered.Regulation of transportation of oilOur sales of crude oil are affected by the availability, terms and cost of transportation. Interstate transportation of oil by pipeline is regulated byFERC pursuant to the Interstate Commerce Act (“ICA”), the Energy Policy Act of 1992 and the rules and regulations promulgated under those laws. The ICAand its implementing regulations require that tariff rates for interstate service on oil pipelines, including interstate pipelines that transport crude oil andrefined products (collectively referred to as “petroleum pipelines”) be just and reasonable and non‑discriminatory and that such rates and terms andconditions of service be filed with FERC.Intrastate oil pipeline transportation rates are subject to regulation by state regulatory commissions. The basis for intrastate oil pipeline regulation, and thedegree of regulatory oversight and scrutiny given to intrastate oil pipeline rates, varies from state to state. Insofar as effective interstate and intrastate rates areequally applicable to all comparable shippers, we believe that the regulation of oil transportation rates will not affect our operations in any way that is ofmaterial difference from those of our competitors who are similarly situated.Regulation of transportation and sales of natural gasHistorically, the transportation and sale for resale of natural gas in interstate commerce have been regulated by agencies of the U.S. federalgovernment, primarily FERC. FERC regulates interstate natural gas transportation rates and service conditions, which affects the marketing of natural gas thatwe produce, as well as the revenues we receive for sales of our natural gas.In the past, the federal government has regulated the prices at which natural gas could be sold. While sales by producers of natural gas can currentlybe made at uncontrolled market prices, Congress could reenact price controls in the future. Deregulation of wellhead natural gas sales began with theenactment of the Natural Gas Policy Act (“NGPA”) and culminated in adoption of the Natural Gas Wellhead Decontrol Act which removed controls affectingwellhead sales of natural gas effective January 1, 1993. The transportation and sale for resale of natural gas in interstate commerce is regulated primarilyunder the Natural Gas Act (“NGA”), and by regulations and orders promulgated under the NGA by FERC. In certain limited circumstances, intrastatetransportation and wholesale sales of natural gas may also be affected directly or indirectly by laws enacted by Congress and by FERC regulations.FERC issued a series of orders in 1996 and 1997 to implement its open access policies. As a result, the interstate pipelines’ traditional role aswholesalers of natural gas has been greatly reduced and replaced by a structure under which pipelines provide transportation and storage service on an openaccess basis to others who buy and sell natural gas. Although FERC’s orders do not directly regulate natural gas producers, they are intended to fosterincreased competition within all phases of the natural gas industry.The Domenici Barton Energy Policy Act of 2005 (“EP Act of 2005”), is a comprehensive compilation of tax incentives, authorized appropriationsfor grants and guaranteed loans, and significant changes to the statutory policy that affects all segments of the energy industry. Among other matters, the EPAct of 2005 amends the NGA to add an anti-market manipulation provision which makes it unlawful for any entity to engage in prohibited behavior to beprescribed by FERC. The EP Act of 2005 provides FERC with the power to assess civil penalties of up to $1,000,000 per day for violations of the NGA andincreases FERC’s civil penalty authority under the NGPA from $5,000 per violation per day to $1,000,000 per violation per day. The civil penalty provisionsare applicable to entities that engage in the sale of natural gas for resale in interstate commerce. On January 19, 2006, FERC issued Order No. 670, a ruleimplementing the anti-market manipulation provision of the EP Act of 2005, and subsequently denied rehearing. The rules make it unlawful: (1) inconnection with the purchase or sale of natural gas subject to the jurisdiction of FERC, or the purchase or sale of transportation more accessible to natural gasservices subject to the jurisdiction of FERC, for any entity, directly or indirectly, to use or employ any device, scheme or artifice to defraud; (2) to make anyuntrue statement of material fact or omit to make any such statement necessary to make the statements made not misleading; or (3) to engage in any act orpractice that operates as a fraud or deceit upon any person. The26 Table of Contentsnew anti-market manipulation rule does not apply to activities that relate only to intrastate or other non-jurisdictional sales or gathering, but does apply toactivities of gas pipelines and storage companies that provide interstate services, as well as otherwise non-jurisdictional entities to the extent the activitiesare conducted “in connection with” gas sales, purchases or transportation subject to FERC jurisdiction, which now includes the annual reportingrequirements under Order 704. The anti-market manipulation rule and enhanced civil penalty authority reflect an expansion of FERC’s NGA enforcementauthority.Gathering service, which occurs upstream of jurisdictional transmission services, is regulated by the states onshore and in state waters. Although itspolicy is still in flux, FERC has reclassified certain jurisdictional transmission facilities as non-jurisdictional gathering facilities, which has the tendency toincrease our costs of getting gas to point of sale locations. State regulation of natural gas gathering facilities generally includes various safety, environmentaland, in some circumstances, nondiscriminatory-take requirements. Although nondiscriminatory-take regulation has not generally been affirmatively appliedby state agencies, natural gas gathering may receive greater regulatory scrutiny in the future.Section 1(b) of the NGA exempts natural gas gathering facilities from regulation by FERC as a natural gas company under the NGA. We believe thatthe natural gas pipelines in our gathering systems meet the traditional tests FERC has used to establish a pipeline’s status as a gatherer not subject toregulation as a natural gas company. However, the distinction between FERC-regulated transmission services and federally unregulated gathering services isthe subject of ongoing litigation, so the classification and regulation of our gathering facilities are subject to change based on future determinations byFERC, the courts or Congress.Our sales of natural gas are also subject to requirements under the Commodity Exchange Act (“CEA”), and regulations promulgated thereunder bythe Commodity Futures Trading Commission (“CFTC”). The CEA prohibits any person from manipulating or attempting to manipulate the price of anycommodity in interstate commerce or futures on such commodity. The CEA also prohibits knowingly delivering or causing to be delivered false ormisleading or knowingly inaccurate reports concerning market information or conditions that affect or tend to affect the price of a commodity.Intrastate natural gas transportation is also subject to regulation by state regulatory agencies. The basis for intrastate regulation of natural gastransportation and the degree of regulatory oversight and scrutiny given to intrastate natural gas pipeline rates and services varies from state to state. Insofaras such regulation within a particular state will generally affect all intrastate natural gas shippers within the state on a comparable basis, we believe that theregulation of similarly situated intrastate natural gas transportation in any states in which we operate and ship natural gas on an intrastate basis will not affectour operations in any way that is of material difference from those of our competitors. Like the regulation of interstate transportation rates, the regulation ofintrastate transportation rates affects the marketing of natural gas that we produce, as well as the revenues we receive for sales of our natural gas.Changes in law and to FERC policies and regulations may adversely affect the availability and reliability of firm and/or interruptible transportationservice on interstate pipelines, and we cannot predict what future action FERC will take. We do not believe, however, that any regulatory changes will affectus in a way that materially differs from the way they will affect other natural gas producers, gatherers and marketers with which we compete.Regulation of productionThe production of oil and natural gas is subject to regulation under a wide range of local, state and federal statutes, rules, orders and regulations.Federal, state and local statutes and regulations require permits for drilling operations, drilling bonds and reports concerning operations. The states in whichwe own and operate properties have regulations governing conservation matters, including provisions for the spacing and unitization or pooling of oil andnatural gas properties, the regulation of well spacing and well density, and procedures for proper plugging and abandonment of wells. The intent of theseregulations is to promote the efficient recovery of oil and gas reserves while reducing waste and protecting correlative rights. By collaborating with industry'sexploration and development operations, these regulations effectively identify where wells can be drilled, well densities by geologic formation along withthe proper spacing and pooling unit size to effectively drain the resources. Operators can apply for exceptions to such regulations including applications toincrease well densities to more effectively recover the oil and gas resources. Moreover, each state generally imposes a production or severance tax withrespect to the production and sale of oil, natural gas and natural gas liquids within its jurisdiction.We own interests in properties located onshore in three U.S. states. These states regulate drilling and operating activities by requiring, among otherthings, permits for the drilling of wells, maintaining bonding requirements in order to drill or operate wells, and regulating the location of wells, the methodof drilling and casing wells, the surface use and restoration of properties upon which wells are drilled and the plugging and abandonment of wells. The lawsof these states also govern a number of environmental and conservation matters, including the handling and disposing or discharge of waste materials, the27 Table of Contentssize of drilling and spacing units or proration units and the density of wells that may be drilled, and the unitization and pooling of oil and gas properties.Regulation of derivativesThe Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”) was passed by Congress and signed into law in July 2010.The Dodd-Frank Act is designed to provide a comprehensive framework for the regulation of the over-the-counter derivatives market with the intent toprovide greater transparency and reduction of risk between counterparties. The Dodd-Frank Act subjects swap dealers and major swap participants to capitaland margin requirements and requires many derivative transactions to be cleared on exchanges. The Dodd-Frank Act provides for a potential exemption fromthese clearing and cash collateral requirements for commercial end-users.Environmental, Health and Safety RegulationOur natural gas and oil exploration and production operations are subject to numerous stringent federal, regional, state and local laws andregulations governing safety and health, the discharge of materials into the environment or otherwise relating to environmental protection, non-compliancewith which can result in substantial administrative, civil and criminal penalties and other sanctions, including suspension or cessation of operations. Theselaws and regulations may require the acquisition of permits before drilling or other regulated activity commences; restrict the types, quantities andconcentrations of various substances that can be released into the environment; govern the sourcing and disposal of water used in the drilling and completionprocess; limit or prohibit drilling activities that impact threatened or endangered species or that occur in certain areas and on certain lands lying withinwilderness, wetlands, frontier and other protected areas; require some form of remedial action to prevent or mitigate pollution from former operations such asplugging abandoned wells or closing earthen pits; establish specific safety and health criteria addressing worker protection and impose substantial liabilitiesfor pollution resulting from operations or failure to comply with regulatory filings. In addition, these laws and regulations may restrict the rate of production.The following is a summary of the more significant existing environmental and health and safety laws and regulations to which we are subject andfor which compliance may have a material adverse impact on our capital expenditures, results of operations or financial position.Hazardous substances and waste handlingThe Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”), also known as the Superfund law, andcomparable state laws impose liability without regard to fault or the legality of the original conduct on certain classes of persons who are considered to beresponsible for the release of a “hazardous substance” into the environment. These persons include current and prior owners or operators of the site where therelease occurred and entities that disposed or arranged for the disposal of the hazardous substances found at the site. Under CERCLA, these potentially“responsible persons” may be subject to strict, joint and several liability for the costs of cleaning up the hazardous substances that have been released intothe environment, for damages to natural resources, and for the costs of certain health studies, and it is not uncommon for neighboring landowners and otherthird parties to file claims for personal injury and property damage allegedly caused by the hazardous substances released into the environment. We are ableto control directly the operation of only those wells with respect to which we act as operator. Notwithstanding our lack of direct control over wells operatedby others, the failure of an operator other than us to comply with applicable environmental regulations may, in certain circumstances, be attributed to us. Wegenerate materials in the course of our operations that may be regulated as hazardous substances but we are not aware of any liabilities for which we may beheld responsible that would materially or adversely affect us.We currently own or lease, and have in the past owned or leased, properties that have been used for numerous years to explore and produce oil andnatural gas. Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons and wastes may havebeen disposed of or released on or under the properties owned or leased by us or on or under the other locations where these hydrocarbons and wastes havebeen taken for treatment or disposal. In addition, certain of these properties have been operated by third parties whose treatment and disposal or release ofhydrocarbons and wastes were not under our control. These properties and wastes disposed thereon may be subject to CERCLA, RCRA and analogous statelaws. Under these laws, we could be required to remove or remediate previously disposed wastes (including wastes disposed of or released by prior owners oroperators), to clean up contaminated property (including groundwater contaminated by prior owners or operators), to pay for damages for the loss orimpairment of natural resources, and to take measures to prevent future contamination from our operations.28 Table of ContentsIn addition, other laws require the reporting on use of hazardous and toxic chemicals. For example, in October 2015, EPA granted, in part, a petitionfiled by several national environmental advocacy groups to add the oil and gas extraction industry to the list of industries required to report releases ofcertain “toxic chemicals” under the Toxic Release Inventory (“TRI”) program under the Emergency Planning and Community Right-to-Know Act. EPAdetermined that natural gas processing facilities may be appropriate for addition to TRI applicable facilities and in January 2017, EPA issued a proposed ruleto include natural gas processing facilities in the TRI program.Pipeline safety and maintenancePipelines, gathering systems and terminal operations are subject to increasingly strict safety laws and regulations. Both the transportation andstorage of refined products and crude oil involve a risk that hazardous liquids may be released into the environment, potentially causing harm to the publicor the environment. In turn, such incidents may result in substantial expenditures for response actions, significant government penalties, liability for naturalresources damages, and significant business interruption. The U.S. Department of Transportation has adopted safety regulations with respect to the design,construction, operation, maintenance, inspection and management of our pipeline and storage facilities. These regulations contain requirements for thedevelopment and implementation of pipeline integrity management programs, which include the inspection and testing of pipelines and the correction ofanomalies. These regulations also require that pipeline operation and maintenance personnel meet certain qualifications and that pipeline operators developcomprehensive spill response plans.There have been recent initiatives to strengthen and expand pipeline safety regulations and to increase penalties for violations. The Pipeline Safety,Regulatory Certainty, and Job Creation Act was signed into law in early 2012. In addition, the Pipeline and Hazardous Materials Safety Administration(“PHMSA”) has issued new rules to strengthen federal pipeline safety enforcement programs. In 2015, PHMSA proposed to expand its regulations in anumber of ways, including through the increased regulation of gathering lines, even in rural areas. In 2016, PHMSA increased its regulations to require crudeoil sampling and reporting as an offeror and increased its civil penalty structure.Air emissionsThe Clean Air Act (“CAA”) and comparable state laws and regulations restrict the emission of air pollutants from many sources, including oil andgas operations, and impose various monitoring and reporting requirements. These laws and regulations may require us to obtain pre-approval for theconstruction or modification of certain projects or facilities expected to produce or significantly increase air emissions, obtain and comply with stringent airpermit requirements or utilize specific equipment or technologies to control emissions. Obtaining required air permits can significantly delay thedevelopment of certain oil and natural gas projects. Over the next several years, we may be required to incur certain capital expenditures for air pollutioncontrol equipment or other air emissions related issues.For example, on August 16, 2012, the EPA published final rules under the CAA that subject oil and natural gas production, processing, transmissionand storage operations to regulation under the New Source Performance Standards (“NSPS”) and National Emission Standards for Hazardous Air Pollutantsprograms. With regards to production activities, these final rules require, among other things, the reduction of volatile organic compound emissions fromthree subcategories of fractured and refractured gas wells for which well completion operations are conducted: wildcat (exploratory) and delineation gaswells; low reservoir pressure non-wildcat and non-delineation gas wells; and all “other” fractured and refractured gas wells. These regulations also establishspecific new requirements regarding emissions from production-related wet seal and reciprocating compressors and from pneumatic controllers and storagevessels. The EPA issued revised rules in 2013 and 2014 in response to requests for reconsideration from industry and the environmental community. Mostrecently, as part of the reconsideration, in May 2016 the EPA issued amendments to the NSPS rules focused on achieving additional methane and volatileorganic compound reductions from oil and natural gas operations. Among other things, these amendments impose new requirements for leak detection andrepair, control requirements for oil well completions, and additional control requirements for gathering, boosting, and compressor stations. Concurrently withthese methane rules, the EPA finalized a new rule regarding source determinations and permitting requirements for the onshore oil and gas industry under theCAA. The EPA also published Control Technique Guidelines aimed at providing states with guidance on Reasonable Achievable Control Technology for theoil and gas industry in areas of ozone non-attainment.On October 1, 2015, EPA finalized its rule lowering the existing 75 part per billion ("ppb") national ambient air quality standard ("NAAQS") forozone under the CAA to 70 ppb. Also in 2015, the State of Colorado received a bump-up in its existing ozone non-attainment status from “marginal” to“moderate.” Oil and natural gas operations in ozone nonattainment areas, including in Colorado, may be subject to increased regulatory burdens in the formof more stringent emission controls, emission offset requirements, and increased permitting delays and costs. In addition, in February 2014, the ColoradoDepartment of Public Health and Environment’s Air Quality Control Commission (“AQCC”) adopted new and revised air quality regulations that imposestringent new requirements to control emissions from existing and new oil and gas facilities in29 Table of ContentsColorado. The proposed regulations include new control, monitoring, recordkeeping, and reporting requirements on oil and gas operators in Colorado. Forexample, the new regulations impose Storage Tank Emission Management (“STEM”) requirements for certain new and existing storage tanks. The STEMrequirements require us to install costly emission control technologies as well as monitoring and recordkeeping programs at most of our new and existingwell production facilities. The new Colorado regulations also impose a Leak Detection and Repair (“LDAR”) program for well production facilities andcompressor stations. The LDAR program primarily targets hydrocarbon (i.e., methane) emissions from the oil and gas sector in Colorado and represents asignificant new use of state authority regarding these emissions.Compliance with these and other air pollution control and permitting requirements has the potential to delay the development of oil and natural gasprojects and increase our costs of development and production, which costs could be significant.Climate changeIn response to findings that emissions of carbon dioxide, methane and other greenhouse gases (“GHGs”) present an endangerment to public healthand the environment, the EPA has adopted regulations under existing provisions of the CAA that, among other things, establish Prevention of SignificantDeterioration (“PSD”) construction and Title V operating permit requirements for certain large stationary sources that include potential major sources of GHGemissions. In June 2014, the United States Supreme Court ruled in Utility Air Regulatory Group v. EPA, No. 12‑1146. The Supreme Court upheld part of theEPA’s GHG-related regulations but struck down other portions of the rules. Specifically, the Supreme Court ruled that sources subject to the PSD or Title Vprograms because of non-GHG emissions could still potentially be subject to certain “best available control technology” requirements applicable to theirGHG emissions. Under the Court’s opinion, sources subject to the PSD or Title V programs due solely to their GHG emissions, however, can no longer besubject to EPA’s GHG permitting requirements. The D.C. Circuit issued an amendment judgment following remand, and EPA intends to conduct futurerulemaking to make revisions conforming to the court rulings. In May 2016, the EPA also finalized a rule regarding source determination, including definingthe term “adjacent” under the CAA, which affects how major sources, including GHG major sources, are regulated. These EPA rulemakings will have nominaleffect on our operations because the rule clarified our existing presumption on “adjacent" and presents no conflict with the State of Colorado regulations. Inaddition, the EPA has adopted rules requiring the monitoring and reporting of GHGs from specified onshore and offshore oil and gas production sources inthe United States on an annual basis, which include certain of our operations. We are monitoring GHG emissions from our operations in accordance with theGHG emissions reporting rule.Congress has, from time to time, considered legislation to reduce emissions of GHGs. In addition, a number of state and regional efforts haveemerged that are aimed at tracking and/or reducing GHG emissions by means of cap and trade programs that typically require major sources of GHGemissions, such as electric power plants, to acquire and surrender emission allowances in return for emitting those GHGs. Most recently, the EPA finalizedrules to further reduce GHG emissions, primarily from coal-fired power plants, under its Clean Power Plan. The Clean Power Plan and associated BLMVenting and Flaring rule may become subject to the Congressional Review Act given the focus of the Trump administration on reduced regulation. If fullyimplemented, the Clean Power Plan could affect the demand for products we supply or otherwise affect our operations. If Congress undertakes comprehensivetax reform in the coming year, it is possible that such reform may include a carbon tax, which could impose additional direct costs on operations and reducedemand for refined products. In January 2015, the EPA announced a comprehensive strategy intended to further reduce methane emissions from the oil andgas sector, which already has resulted in the final May 2016 amendments to the 2012 NSPS and the related source determination rule noted above and mayresult in additional regulation. Although it is not possible at this time to predict how legislation or new regulations that may be adopted to address GHGemissions would impact our business, any such future laws and regulations imposing reporting obligations on, or limiting emissions of GHGs from ourequipment and operations could require us to incur costs to reduce emissions of GHGs associated with our operations. Severe limitations on GHG emissionscould adversely affect demand for the oil and natural gas we produce.Water dischargesThe Federal Water Pollution Control Act or the Clean Water Act (“CWA”) and analogous state laws impose restrictions and controls regarding thedischarge of pollutants into certain surface waters. In 2016, the definition of waters of the United States was substantially expanded which may have effect onour current and future operations. The Trump administration has identified this rule change as one that may be rescinded using the Congressional Review Actor other means. Pursuant to these laws and regulations, we may be required to obtain and maintain approvals or permits for the discharge of wastewater orstorm water and are required to develop and implement spill prevention, control and countermeasure plans, also referred to as “SPCC plans,” in connectionwith on‑site storage of significant quantities of oil. As properties are acquired, we determine the need for new or updated SPCC plans and, where necessary,will develop or update such plans to implement physical and operation controls, the costs of which are not expected to be material. In June 2015, the EPAand the U.S. Army30 Table of ContentsCorps of Engineers adopted a new regulatory definition of "waters of the U.S.," which governs which waters and wetlands are subject to the CWA. This finalrule has been stayed pending the resolution of ongoing litigation, and in February 2017, President Trump signed an executive order directing EPA to beginrescinding or revising this final rule. In June 2016, EPA finalized new CWA pretreatment standards that would prevent onshore unconventional oil andnatural gas wells from discharging wastewater pollutants to publicly-owned treatment facilities.Endangered Species ActThe federal Endangered Species Act restricts activities that may affect endangered and threatened species or their habitats. A final rule amendinghow critical habitat is designated was finalized in 2016. Some of our facilities may be located in areas that are designated as habitat for endangered orthreatened species. The designation of previously unidentified endangered or threatened species could cause us to incur additional costs or become subjectto operating restrictions or bans in the affected areas.Employee health and safetyWe are subject to a number of federal and state laws and regulations, including the federal Occupational Safety and Health Act (the “OSH Act”), andcomparable state statutes, whose purpose is to protect the health and safety of workers. In 2016, there were substantial revisions to the OSHA regulations thatmay have impact to our operations. These changes include among other items; record keeping and reporting, revised crystalline silica standard, naming oiland gas as a high hazard industry, requirements for a safety and health management system. In addition, the OSH Act’s hazard communication standard, theEPA community right-to-know regulations under Title III of the federal Superfund Amendment and Reauthorization Act and comparable state statutes requirethat information be maintained concerning hazardous materials used or produced in our operations, and that this information be provided to employees, stateand local government authorities and citizens.Hydraulic fracturingRegulations relating to hydraulic fracturing. We are subject to extensive federal, state, and local laws and regulations concerning health, safety, andenvironmental protection. Government authorities frequently add to those requirements, and both oil and gas development generally and hydraulicfracturing specifically are receiving increasing regulatory attention. Our operations utilize hydraulic fracturing, an important and commonly used process inthe completion of oil and natural gas wells in low-permeability formations. Hydraulic fracturing involves the injection of water, proppant, and chemicalsunder pressure into rock formations to stimulate hydrocarbon production.States have historically regulated oil and gas exploration and production activity, including hydraulic fracturing. State governments in the areaswhere we operate have adopted or are considering adopting additional requirements relating to hydraulic fracturing that could restrict its use in certaincircumstances or make it more costly to utilize. Such measures may address any risk to drinking water, the potential for hydrocarbon migration and disclosureof the chemicals used in fracturing. Colorado, for example, comprehensively updated its oil and gas regulations in 2008 and adopted significant additionalamendments in 2011 and 2013. Among other things, the updated and amended regulations require operators to reduce methane emissions associated withhydraulic fracturing, compile and report additional information regarding well bore integrity, publicly disclose the chemical ingredients used in hydraulicfracturing, increase the minimum distance between occupied structures and oil and gas wells, undertake additional mitigation for nearby residents, andimplement additional groundwater testing. In 2014, the State enacted legislation to increase the potential sanctions for statutory, regulatory and otherviolations. Among other things, this legislation and its implementing regulations mandate monetary penalties for certain types of violations, require apenalty to be assessed for each day of violation and significantly increase the maximum daily penalty amount. Most recently, Colorado adopted rulesimposing additional permitting requirements for certain large scale facilities in urban mitigation areas and additional notice requirements prior to engagingin operations near certain municipalities. Any enforcement actions or requirements of additional studies or investigations by governmental authorities wherewe operate could increase our operating costs and cause delays or interruptions of our operations.The federal Safe Drinking Water Act (“SDWA”) and comparable state statutes may restrict the disposal, treatment or release of water produced orused during oil and gas development. Subsurface emplacement of fluids, primarily via disposal wells or enhanced oil recovery (“EOR”) wells, is governed byfederal or state regulatory authorities that, in some cases, include the state oil and gas regulatory or the state’s environmental authority. The federal EnergyPolicy Act of 2005 amended the Underground Injection Control provisions of the SDWA to expressly exclude certain hydraulic fracturing from the definitionof “underground injection,” but disposal of hydraulic fracturing fluids and produced water or their injection for EOR is not excluded. Congress hasconsidered bills to repeal this SDWA exemption for hydraulic fracturing. If enacted, hydraulic fracturing operations could be required to meet additionalfederal permitting and financial assurance requirements, adhere to31 Table of Contentscertain construction specifications, fulfill monitoring, reporting, and recordkeeping obligations, meet plugging and abandonment requirements, and provideadditional public disclosure of chemicals used in the fracturing process.Federal agencies are also considering additional regulation of hydraulic fracturing. The EPA has published guidance for issuing undergroundinjection permits that would regulate hydraulic fracturing using diesel fuel. This guidance eventually could encourage other regulatory authorities to adoptpermitting and other restrictions on the use of hydraulic fracturing. In addition, on October 21, 2011, the EPA announced its intention to propose regulationsunder the CWA to regulate wastewater discharges from hydraulic fracturing and other natural gas production. As noted above, in June 2016, EPA finalizedregulations that address discharges of wastewater pollutants from onshore unconventional extraction facilities to publicly-owned treatment works. The EPAis also collecting information as part of a nationwide study into the effects of hydraulic fracturing on drinking water. The EPA issued a progress reportregarding the study in December 2012, which described generally the continuing focus of the study, but did not provide any data, findings, or conclusionsregarding the safety of hydraulic fracturing operations. In June 2015, the EPA released a draft assessment of the potential impacts to drinking water resourcesfrom hydraulic fracturing. The Agency will finalize the assessment following public comment and review. The results of this study could result in additionalregulations, which could lead to operational burdens similar to those described above. The EPA also has initiated a stakeholder and potential rulemakingprocess under the Toxic Substances Control Act (“TSCA”) to obtain data on chemical substances and mixtures used in hydraulic fracturing. The EPA has notindicated when it intends to issue a proposed rule, but it issued an Advanced Notice of Proposed Rulemaking in May 2014, seeking public comment on avariety of issues related to the TSCA rulemaking. As noted above, in January 2017, the EPA issued a proposed rule to include natural gas processing facilitiesin the TRI program. The United States Department of the Interior also finalized a new rule regulating hydraulic fracturing activities on federal lands,including requirements for disclosure, well bore integrity and handling of flowback water. This rule has been stayed pending the outcome of ongoinglitigation. In early 2016, the Bureau of Land Management (“BLM”) proposed rules related to further controlling the venting and flaring of natural gas onBLM land which the U.S. House of Representative passed resolution to repeal. The U.S. Occupational Safety and Health Administration has proposed stricterstandards for worker exposure to silica, which would apply to use of sand as a proppant for hydraulic fracturing. In addition, the Department of Labor and theDepartment of Justice, Environment and Natural Resources Division released a Memorandum of Understanding announcing an inter-agency effort to increasethe enforcement of workplace safety crimes that occur in conjunction with environmental crimes.Apart from these ongoing federal and state initiatives, local governments are adopting new requirements on hydraulic fracturing and other oil andgas operations. Voters in Colorado have proposed or advanced initiatives restricting or banning oil and gas development in Colorado. Any successful bans ormoratoriums where we operate could increase the costs of our operations, impact our profitability, and even prevent us from drilling in certain locations.At this time, it is not possible to estimate the potential impact on our business of recent state and local actions or the enactment of additional federalor state legislation or regulations affecting hydraulic fracturing. The adoption of future federal, state or local laws or implementing regulations imposing newenvironmental obligations on, or otherwise limiting, our operations could make it more difficult and more expensive to complete oil and natural gas wells,increase our costs of compliance and doing business, delay or prevent the development of certain resources (including especially shale formations that arenot commercial without the use of hydraulic fracturing), or alter the demand for and consumption of our products and services. We cannot assure you that anysuch outcome would not be material, and any such outcome could have a material and adverse impact on our cash flows and results of operations.Our use of hydraulic fracturing. We use hydraulic fracturing as a means to maximize production of oil and gas from formations having lowpermeability such that natural flow is restricted. Fracture stimulation has been used for decades in both the Rocky Mountains and Mid-Continent.Typical hydraulic fracturing treatments are made up of water, chemical additives and sand. We utilize major hydraulic fracturing service companieswho track and report additive chemicals that are used in fracturing as required by the appropriate government agencies. Each of these companies fracturestimulate a multitude of wells for the industry each year.We periodically review our plans and policies regarding oil and gas operations, including hydraulic fracturing, in order to minimize any potentialenvironmental impact. Our operations are subject to close supervision by state and federal regulators (including the BLM with respect to federal acreage),who frequently inspect our fracturing operations.National Environmental Policy ActNatural gas and oil exploration and production activities on federal lands are subject to the National Environmental Policy Act (“NEPA”). NEPArequires federal agencies, including the Departments of Interior and Agriculture, to evaluate major32 Table of Contentsagency actions having the potential to significantly impact the environment. In the course of such evaluations, an agency prepares an EnvironmentalAssessment to evaluate the potential direct, indirect and cumulative impacts of a proposed project. If impacts are considered significant, the agency willprepare a more detailed environmental impact study that is made available for public review and comment. All of our current exploration and productionactivities, as well as proposed exploration and development plans, on federal lands require governmental permits that are subject to the requirements ofNEPA. The vast majority of our exploration and production activities are not on federal lands. This environmental impact assessment process has thepotential to delay or limit, or increase the cost of, the development of natural gas and oil projects on federal lands. Authorizations under NEPA also aresubject to protest, appeal or litigation, which can delay or halt projects.Oil Pollution ActThe Oil Pollution Act of 1990 (“OPA”) establishes strict liability for owners and operators of facilities that are the site of a release of oil into watersof the U.S. The OPA and its associated regulations impose a variety of requirements on responsible parties related to the prevention of oil spills and liabilityfor damages resulting from such spills. A “responsible party” under the OPA includes owners and operators of certain onshore facilities from which a releasemay affect waters of the U.S. The OPA assigns liability to each responsible party for oil cleanup costs and a variety of public and private damages. Whileliability limits apply in some circumstances, a party cannot take advantage of liability limits if the spill was caused by gross negligence or willful misconductor resulted from violation of a federal safety, construction or operating regulation. If the party fails to report a spill or to cooperate fully in the cleanup,liability limits likewise do not apply. Few defenses exist to the liability imposed by the OPA. The OPA imposes ongoing requirements on a responsible party,including the preparation of oil spill response plans and proof of financial responsibility to cover environmental cleanup and restoration costs that could beincurred in connection with an oil spill.State lawsOur properties located in Colorado are subject to the authority of the Colorado Oil and Gas Conservation Commission (the “COGCC”), as well asother state agencies. The COGCC recently approved new rules regarding minimum setbacks, groundwater monitoring, large-scale facilities in urbanmitigation areas, and public notice requirements that are intended to prevent or mitigate environmental impacts of oil and gas development and include thepermitting of wells. Over the past several years, the COGCC has also approved new rules regarding various other matters, including wellbore integrity,hydraulic fracturing, well control waste management, spill reporting, and an increase in potential sanctions for COGCC rule’s violations. Depending on howthese and any other new rules are applied, they could add substantial increases in well costs for our Colorado operations. The rules could also impact ourability and extend the time necessary to obtain drilling permits, which would create substantial uncertainty about our ability to meet future drilling plans andthus production and capital expenditure targets. The State of Colorado also created a task force to make recommendations for minimizing land use and otherconflicts concerning the location of new oil and gas facilities. In February 2015, the task force concluded their deliberations and agreed upon nine consensusproposals which were sent to Governor Hickenlooper for his review. Three of the proposals require further legislative action, while the other six proposalsrequire rulemaking or other regulatory action. The proposals support (i) a senate bill that would postpone expiration of recently adopted regulations,regarding air emissions; (ii) tasking the COGCC with crafting new rules related to siting of “large-scale” pads and facilities; (iii) requiring the industry toprovide advance information about development plans to local governments; (iv) improving the COGCC’s local government liaison and designee programs;(v) adding 11 full-time staffers to the COGCC; (vi) bolstering the inspection staff and equipment for monitoring oil and gas facility air emissions and settingup a hotline for citizen health complaints at the Colorado Department of Public Health and Environment; (vii) creating a statewide oil and gas informationclearinghouse; (viii) studying ways to ameliorate the impact of oil and gas truck traffic and (ix) creating a compliance-assistance program at the COGCC tohelp operators comply with the state's changing rules and ensure consistent enforcement of rules by state inspectors. A number of additional proposals did notreceive sufficient task force support to be included with the nine consensus proposals, but may nevertheless be forwarded to the Governor as well.In 2015 and into 2016, COGCC implemented two of these recommendations (in particular items (ii) and (iii) identified above). With respect torecommendation (ii) above, the COGCC finalized rules to permit “large-scale facilities” in “urban mitigation areas.” With respect to recommendation (iii)above, the COGCC finalized rules to require operators to provide certain municipalities with public notice prior to engaging in operations.In 2016, the Colorado Supreme Court ruled that the cities of Fort Collins and Longmont do not have authority to ban oil and gas operations withintheir jurisdictional limits. Although we do not own or operate within any of these municipal areas, the Colorado Supreme Court decision has bearing on ourability to continue to operate in Colorado. Further, Weld County completed implementation of a local government permitting process for land use approval.We do not expect that the local government issues will have any material impact on our operations.33 Table of ContentsEmployeesAs of December 31, 2016, we employed 231 people and also utilized the services of independent contractors to perform various field and otherservices. Our future success will depend partially on our ability to attract, retain and motivate qualified personnel. We are not a party to any collectivebargaining agreements and have not experienced any strikes or work stoppages.OfficesAs of December 31, 2016, we leased 83,463 square feet of office space in Denver, Colorado at 410 17th Street where our principal offices are locatedand leased 7,780 square feet near our operations in Weld County, Colorado, where we have a field office and storage facilities. We also own field offices inEvans, Colorado and Magnolia, Arkansas.Available informationWe are required to file annual, quarterly and current reports, proxy statements and other information with the SEC.

Information contained on our website, other than the documents listed below,is not incorporated by reference into this Annual Report on Form 10‑K.Item 1A. Risk Factors.Our business involves a high degree of risk. If any of the following risks, or any risk described elsewhere in this Annual Report on Form 10-K,actually occurs, our business, financial condition or results of operations could suffer. The risks described below are not the only ones facing us. Additionalrisks not presently known to us or which we currently consider immaterial also may adversely affect us.Risks Related to Bankruptcy:We are subject to risks and uncertainties associated with our Chapter 11 cases.On January 4, 2017, the Company along with six of its subsidiaries, including Bonanza Creek Energy Operating Company, LLC, Bonanza CreekEnergy Resources, LLC, Holmes Eastern Company, LLC, Rocky Mountain Infrastructure, LLC, Bonanza Creek Energy Upstream LLC, and Bonanza CreekEnergy Midstream, LLC, filed voluntary petitions seeking relief under Chapter 11 of the United States Bankruptcy Code.Our operations and ability to develop and execute our business plan, our financial condition, our liquidity and our continuation as a going concern,are subject to the risks and uncertainties associated with our bankruptcy. These risks include the following:•our ability to prosecute, confirm and consummate a plan of reorganization with respect to the Chapter 11 cases;•the high costs of bankruptcy cases and related fees;•our ability to obtain sufficient financing to allow us to emerge from bankruptcy and execute our business plan post-emergence;•our ability to maintain our relationships with our suppliers, service providers, customers, employees, and other third parties;•our ability to maintain contracts that are critical to our operations;•our ability to safely and efficiently re-start operations after a protracted period of minimal activity;34 Table of Contents•our ability to execute competitive contracts with third party contractors while tainted with a bankruptcy legacy;•our ability to execute our business plan in the current commodity price environment;•our ability to attract, motivate and retain key employees;•the ability of third parties to seek and obtain court approval to terminate contracts and other agreements with us;•our ability to retain our current management team if a trustee is appointed;•the ability of third parties to seek and obtain court approval to convert the Chapter 11 cases to a Chapter 7 proceeding; and•the actions and decisions of our creditors and other third parties who have interests in our Chapter 11 cases that may be inconsistent with ourplans.Delays in our Chapter 11 cases increase the risks of our being unable to reorganize our business and emerge from bankruptcy and increase our costsassociated with the bankruptcy process.These risks and uncertainties could affect our business and operations in various ways. For example, negative events or publicity associated with ourChapter 11 cases could adversely affect our relationships with our suppliers, service providers, customers, employees, and other third parties, which in turncould adversely affect our operations and financial condition. Also, pursuant to the Bankruptcy Code, we need the prior approval of the Bankruptcy Court fortransactions outside the ordinary course of business, which may limit our ability to respond timely to certain events or take advantage of certainopportunities. We also need Bankruptcy Court confirmation of the Plan. Because of the risks and uncertainties associated with our Chapter 11 cases, wecannot accurately predict or quantify the ultimate impact of events that occur during our Chapter 11 cases will have on our business, financial condition andresults of operations, and there is no certainty as to our ability to continue as a going concern.We may not be able to obtain confirmation of a Chapter 11 plan of reorganization.To emerge successfully from Bankruptcy Court protection as a viable entity, we must meet certain statutory requirements with respect to adequacyof disclosure with respect to a Chapter 11 plan of reorganization, solicit and obtain the requisite acceptances of such a reorganization plan and fulfill otherstatutory conditions for confirmation of such a plan. Although we have distributed to our creditors a disclosure statement with respect to the Plan and oursolicitation of the Plan has been completed, certain parties in interest have filed objections to the Plan in an effort to persuade the Bankruptcy Court that wehave not satisfied the confirmation requirements under section 1129 of the Bankruptcy Code. Those objections have not yet been addressed or ruled on bythe Bankruptcy Court. The precise requirements and evidentiary showing for confirming a plan, notwithstanding its rejection by one or more impaired classesof claims or equity interests, depends upon a number of factors including, without limitation, the status and seniority of the claims or equity interests in therejecting class (i.e., secured claims or unsecured claims, subordinated or senior claims, preferred or common stock).A confirmation hearing on the Prepackaged Plan has been scheduled to begin on April 3, 2017, but it is possible that hearing could be delayed. It isalso possible that the Bankruptcy Court will not confirm the Prepackaged Plan. If the Prepackaged Plan is not confirmed by the Bankruptcy Court, it isunclear whether we would be able to reorganize our business and what, if anything, holders of claims against us would ultimately receive with respect to theirclaims.Even if a Chapter 11 plan of reorganization is consummated, we may not be able to achieve our stated goals and continue as a going concern.Even if the Prepackaged Plan or another Chapter 11 plan of reorganization is consummated, we will continue to face a number of risks, includingfurther deterioration in commodity prices or other changes in economic conditions, changes in our industry, changes in demand for our oil and gas andincreasing expenses. Accordingly, we cannot guarantee that the Plan or any other Chapter 11 plan of reorganization will achieve our stated goals.Our proposed Prepackaged Plan contemplates a $200 million rights offering that would strengthen our liquidity at emergence. However, if this rightsoffering is not approved by the Bankruptcy Court or otherwise does not occur, and even if our debts are reduced or discharged through a different confirmedplan, we may need to raise additional funds through public or private debt or equity financing or other various means to fund our business after thecompletion of our Chapter 11 cases. Our access to additional financing is, and for the foreseeable future will likely continue to be, extremely limited, if it isavailable at all. Therefore, adequate funds may not be available when needed or may not be available on favorable terms, if they are available at all. Ourability to continue as a going concern is dependent upon our ability to raise additional capital. As a result, we cannot give any assurance of our ability tocontinue as a going concern, even if a plan is confirmed.35 Table of ContentsWe have substantial liquidity needs and may not be able to obtain sufficient liquidity to confirm a plan of reorganization and exit bankruptcy.Although we have lowered our capital budget and reduced the scale of our operations significantly, our business remains capital intensive. Inaddition to the cash requirements necessary to fund ongoing operations, we have incurred significant professional fees and other costs in connection with ourChapter 11 cases and expect that we will continue to incur significant professional fees and costs throughout our Chapter 11 cases. Although we currentlyhave $80.6 million of cash on hand, there are no assurances that our current liquidity is sufficient to allow us to satisfy our obligations related to the Chapter11 cases, allow us to proceed with the confirmation of a Chapter 11 plan of reorganization and allow us to emerge from bankruptcy. We can provide noassurance that we will be able to secure additional interim financing or exit financing sufficient to meet our liquidity needs or, if sufficient funds areavailable, offered to us on acceptable terms.In certain instances, a Chapter 11 case may be converted to a case under Chapter 7 of the Bankruptcy Code.Upon a showing of cause, the Bankruptcy Court may convert our Chapter 11 case to a case under Chapter 7 of the Bankruptcy Code. In such event, aChapter 7 trustee would be appointed or elected to liquidate our assets for distribution in accordance with the priorities established by the Bankruptcy Code.We believe that liquidation under Chapter 7 would result in significantly smaller distributions being made to our creditors than those provided for in ourPlan because of (i) the likelihood that the assets would have to be sold or otherwise disposed of in a distressed fashion over a short period of time rather thanin a controlled manner and as a going concern, (ii) additional administrative expenses involved in the appointment of a Chapter 7 trustee, and (iii) additionalexpenses and claims, some of which would be entitled to priority, that would be generated during the liquidation and from the rejection of leases and otherexecutory contracts in connection with a cessation of operations.We believe it is highly likely that the shares of our existing common stock will be canceled in our Chapter 11 cases.The Prepackaged Plan provides, among other things, that upon our emergence from bankruptcy, our existing common stock will be canceled, andthe holders of our existing common stock will receive 4.5 percent of our post-emergence common stock (subject to dilution from a $200 million rightsoffering, a new management incentive plan, and warrants for existing equity holders) plus warrants to acquire up to 7.5 percent of the post-emergencecommon stock. If the Prepackaged Plan is confirmed by the Bankruptcy Court, the existing shareholders’ post-emergence shares of common stock andwarrants may be subject to further dilution due to subsequent capital raising activities. Additionally, the Prepackaged Plan may not be confirmed by theBankruptcy Court, in which case, the chance that the existing shareholders will receive little or no distribution in our Chapter 11 cases may increase.Accordingly, any trading in shares of our common stock during the pendency of the Chapter 11 cases is highly speculative.We may be subject to claims that will not be discharged in our Chapter 11 cases, which could have a material adverse effect on our financial condition andresults of operations.The Bankruptcy Code provides that the confirmation of a Chapter 11 plan of reorganization discharges a debtor from substantially all debts arisingprior to confirmation. With few exceptions, all claims that arose prior to confirmation of the plan of reorganization (i) would be subject to compromise and/ortreatment under the plan of reorganization and (ii) would be discharged in accordance with the Bankruptcy Code and the terms of the plan of reorganization.Any claims not ultimately discharged through a Chapter 11 plan of reorganization could be asserted against the reorganized entities and may have an adverseeffect on our financial condition and results of operations on a post-reorganization basis.Our financial results may be volatile and may not reflect historical trends.During the Chapter 11 cases, we expect our financial results to continue to be volatile as asset impairments, asset dispositions, restructuringactivities and expenses, contract terminations and rejections, and claims assessments may significantly impact our consolidated financial statements. As aresult, our historical financial performance is likely not indicative of our financial performance after the date of the bankruptcy filing.In addition, if we emerge from Chapter 11, the amounts reported in subsequent consolidated financial statements may materially change relative tohistorical consolidated financial statements, including as a result of revisions to our operating plans pursuant to a plan of reorganization. We expect to berequired to adopt fresh start accounting, in which case our assets and liabilities will be recorded at fair value as of the fresh start reporting date, which maydiffer materially from the recorded values of assets36 Table of Contentsand liabilities on our consolidated balance sheets. Our financial results after the application of fresh start accounting also may be different from historicaltrends.Transfers of our equity, or issuances of equity in connection with our Chapter 11 cases, may impair our ability to utilize our federal income tax netoperating loss carryforwards and depreciation, depletion and amortization deductions in future years.Under federal income tax law, a corporation is generally permitted to deduct from taxable income net operating losses carried forward from prioryears. We have net operating loss carryforwards of approximately $618.5 million as of December 31, 2016. Our ability to utilize our net operating losscarryforwards to offset future taxable income and to reduce federal income tax liability is subject to certain requirements and restrictions. If we experience an“ownership change,” as defined in section 382 of the Internal Revenue Code, then our ability to use our net operating loss carryforwards and amortizable taxbasis in our properties may be substantially limited, which could have a negative impact on our financial position and results of operations. Generally, thereis an “ownership change” if one or more stockholders owning 5% or more of a corporation’s common stock have aggregate increases in their ownership ofsuch stock of more than 50 percentage points over the prior three-year period. Following the implementation a plan of reorganization, it is possible that an“ownership change” may be deemed to occur. Under section 382 of the Internal Revenue Code, absent an applicable exception, if a corporation undergoes an“ownership change,” the amount of its net operating losses that may be utilized to offset future taxable income generally is subject to an annual limitation.Further, future deductions for depreciation, depletion and amortization could be limited if the fair value of our assets is determined to be less than the taxbasis.Our plan for reorganizing the Company may be delayed or altered due to actions by current equity security holders who disagree with our approach torestructuring.Certain holders of the Bonanza Creek Energy, Inc.’s common shares have formed an ad hoc committee of equity security holders (the “Ad HocEquity Committee”) and have filed motions and other pleadings in the Chapter 11 Cases adverse to the Restructuring contemplated by the RSA. In particular,on February 3, 2017, the Ad Hoc Equity Committee filed a motion (the “Trustee Motion”) for an order appointing a trustee pursuant to section 1104(a) of theBankruptcy Code or, in the alternative, appointing an examiner pursuant to section 1104(c) of the Bankruptcy Code. If the Trustee Motion were granted withrespect to the Ad Hoc Equity Committee’s request for the appointment of a trustee, then the Debtors would cease to be debtors in possession and the affairsand management of the business would be controlled by a court-appointed trustee.Risks Related to Our BusinessFurther declines, in oil and, to a lesser extent, natural gas prices, will adversely affect our business, financial condition or results of operations and ourability to meet our capital expenditure obligations or targets and financial commitments.The price we receive for our oil and, to a lesser extent, natural gas and NGLs, heavily influences our revenue, profitability, cash flows, liquidity, theborrowing base under any revolving credit facility that we are able to enter into following emergence from our Chapter 11 cases, access to capital, presentvalue and quality of our reserves, the nature and scale of our operations and future rate of growth. Oil and natural gas are commodities and, therefore, theirprices are subject to wide fluctuations in response to relatively minor changes in supply and demand. In recent years, the markets for oil and natural gas havebeen volatile. These markets will likely continue to be volatile in the future. Further, oil prices and natural gas prices do not necessarily fluctuate in directrelation to each other. Because approximately 75% of our estimated proved reserves as of December 31, 2016 were oil and NGLs, our financial results aremore sensitive to movements in oil prices. Since mid-2014, the price of crude oil has significantly declined. As a result, we experienced significant decreasesin crude oil revenues and recorded asset impairment charges due to commodity price declines. A prolonged period of low market prices for oil, natural gasand NGLs, like the current commodity price environment, or further declines in the market prices for oil and natural gas, will result in capital expendituresbeing further curtailed and will adversely affect our business, financial condition and liquidity and our ability to meet obligations, targets or financialcommitments. During the year ended December 31, 2016, the daily NYMEX WTI oil spot price ranged from a high of $54.01 per Bbl to a low of $26.19 perBbl, and the NYMEX natural gas HH spot price ranged from a high of $3.80 per MMBtu to a low of $1.49 per MMBtu. As of March 10, 2016, the dailyNYMEX WTI oil spot price and NYMEX natural gas HH spot price was $48.49 per Bbl and $3.01 per MMBtu, respectively.The prices we receive for our production, and the levels of our production, depend on numerous factors beyond our control. These factors include,but are not limited to, the following:•worldwide and regional economic conditions impacting the global supply and demand for oil and natural gas;•the actions from members of the Organization of Petroleum Exporting Countries and other oil producing nations;•the price and quantity of imports of foreign oil and natural gas;37 Table of Contents•political conditions in or affecting other oil-producing and natural gas-producing countries, including the current conflicts in the Middle East andconditions in South America and Russia;•the level of global oil and natural gas exploration and production;•the level of global oil and natural gas inventories;•localized supply and demand fundamentals and transportation availability;•weather conditions and natural disasters;•domestic and foreign governmental regulations;•speculation as to the future price of oil and the speculative trading of oil and natural gas futures contracts;•the price and availability of competitors' supplies of oil and natural gas;•technological advances affecting energy consumption;•variability in subsurface reservoir characteristics, particularly in areas with immature development history;•the availability of pipeline capacity and infrastructure; and•the price and availability of alternative fuels.Substantially all of our production is sold to purchasers under contracts at market-based prices. Declines in commodity prices may have thefollowing effects on our business:•reduction of our revenues, profit margins, operating income and cash flows;•reduction in the amount of crude oil, natural gas and NGLs that we can produce economically and may lead to reduced liquidity and the inability topay our liabilities as they come due;•certain properties in our portfolio becoming economically unviable;•delay or postponement of some of our capital projects;•significant reductions in future capital programs, resulting in a reduced ability to develop our reserves;•limitations on our financial condition, liquidity and/or ability to finance planned capital expenditures and operations;•reduction to the borrowing base under our revolving credit facility or limitations in our access to sources of capital, such as equity or debt;•declines in our stock price;•refinery industry demand for crude oil;•storage availability for crude oil;•the ability of our vendors, suppliers, and customers to continue operations due to the prevailing adverse market conditions;•asset impairment charges resulting from reductions in the carrying values of our crude oil and natural gas properties at the date of assessment.Our production is not hedged, and we are exposed to fluctuations in the price of oil and will be affected by continuing and prolonged declines in the priceof oil and natural gas.Oil and natural gas prices are volatile, and the Company currently has none of its anticipated future production hedged. As a result, all of our futureproduction will be sold at market prices, exposing us to the fluctuations in the price of oil and natural gas, unless we enter into new hedging transactions. Tothe extent that the price of oil and natural gas decline below current levels, our results of operations and financial condition would be materially adverselyimpacted. See the Derivative Activity section in Part I, Item I of this Annual Report on Form 10-K for a summary of our hedging activity.38 Table of ContentsDue to reduced commodity prices and lower operating cash flows we may be unable to maintain adequate liquidity and our ability to make interestpayments in respect of our indebtedness could be adversely affected.Recent declines in commodity prices have caused a reduction in our available liquidity, and we are now in bankruptcy. While we anticipate thatsubstantially all of our $800.0 million of long-term unsecured indebtedness will be discharged upon confirmation of a plan of reorganization, we willcontinue to have substantial capital needs upon emergence from bankruptcy, including in connection with the continued development of our oil and gasassets. We may not have the ability to generate sufficient cash flows from operations and, therefore, sufficient liquidity to meet our anticipated workingcapital, debt service and other liquidity needs.Concerns over general economic, business or industry conditions may have a material adverse effect on our results of operations, liquidity and financialcondition.Concerns over global economic conditions, energy costs, geopolitical issues, inflation, the availability and cost of credit, the European, Asian andthe United States financial markets have contributed to increased economic uncertainty and diminished expectations for the global economy. In addition,continued hostilities in the Middle East and the occurrence or threat of terrorist attacks in the United States or other countries could adversely affect theglobal economy. These factors, combined with volatility in commodity prices, business and consumer confidence and unemployment rates, have precipitatedan economic slowdown. Concerns about global economic growth have had a significant adverse impact on global financial markets and commodity prices. Ifthe economic climate in the United States or abroad deteriorates, worldwide demand for petroleum products could diminish further, which could impact theprice at which we can sell our production, affect the ability of our vendors, suppliers and customers to continue operations and ultimately adversely impactour results of operations, liquidity and financial condition.Borrowings under our revolving credit facility are limited by our borrowing base, which is subject to periodic redetermination.We anticipate that the borrowing base under our revolving credit facility upon our emergence from bankruptcy will be redetermined on a periodicbasis based upon a number of factors, including commodity prices and reserve levels. In addition, our lenders will also have substantial flexibility to reduceour borrowing base due to subjective factors. Upon a redetermination, we could be required to repay a portion of our bank debt to the extent our outstandingborrowings at such time exceed the redetermined borrowing base. We may not have sufficient funds to make such repayments, which could result in a defaultunder the terms of the facility and an acceleration of the loans thereunder requiring us to negotiate renewals, arrange new financing or sell significant assets,all of which could have a material adverse effect on our business and financial results.Drilling for and producing oil and natural gas are high-risk activities with many uncertainties that could adversely affect our business, financial conditionor results of operations.Our future financial condition and results of operations will depend on the success of our exploitation, exploration, development and productionactivities. Our oil and natural gas exploration and production activities are subject to numerous risks beyond our control, including the risk that drilling willnot result in commercially viable oil or natural gas production. Our decisions to purchase, explore, develop or otherwise exploit drilling locations orproperties will depend in part on the evaluation of data obtained through geophysical and geological analyses, production data and engineering studies, theresults of which are often inconclusive or subject to varying interpretations. For a discussion of the uncertainty involved in these processes, see Our estimatedproved reserves are based on many assumptions that may turn out to be inaccurate. Any significant inaccuracies in these reserve estimates or underlyingassumptions will materially affect the quantities and present value of our reserves below. Our cost of drilling, completing and operating wells is oftenuncertain before drilling commences. Overruns in budgeted expenditures are common risks that can make a particular project uneconomical. Further, manyfactors, including, but not limited to, the following, may result in substantial losses, including personal injury or loss of life, penalties, damage or destructionof property and equipment, and curtailments, delays or cancellations of our scheduled drilling projects:•shortages of or delays in obtaining equipment and qualified personnel;•facility or equipment malfunctions;•unexpected operational events;•unanticipated environmental liabilities;•pressure or irregularities in geological formations;•adverse weather conditions, such as blizzards, ice storms, tornadoes, floods, and fires;39 Table of Contents•reductions in oil and natural gas prices;•delays imposed by or resulting from compliance with regulatory requirements, such as permitting delays;•proximity to and capacity of transportation facilities;•title problems;•safety concerns, and•limitations in the market for oil and natural gas.Our estimated proved reserves and our ultimate number of prospective well development locations are based on many assumptions that may turn out to beinaccurate. Any significant inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and present value of ourreserves.The process of estimating oil and natural gas reserves and the production possible from our oil and gas wells is complex. It requires interpretations ofavailable technical data and many assumptions, including assumptions relating to current and future economic conditions and commodity prices. Anysignificant inaccuracies in these interpretations or assumptions could materially affect the estimated quantities and present value of reserves shown in thisAnnual Report on Form 10-K. See Estimated Proved Reserves under Part I, Item 1 of this Annual Report on Form 10-K for information about our estimated oiland natural gas reserves and the PV-10 (a non-GAAP financial measure) as of December 31, 2016, 2015 and 2014.In order to prepare our estimates, we must project production rates and the timing of development expenditures. We must also analyze availablegeological, geophysical, production and engineering data. The extent, quality and reliability of this data can vary. The process also requires economicassumptions about matters such as oil and natural gas prices, drilling and operating expenses, capital expenditures, taxes and availability of funds, and giventhe current volatility in pricing, such assumptions are difficult to make. Although the reserve information contained herein is reviewed by independentreserve engineers, estimates of oil and natural gas reserves are inherently imprecise particularly as they relate to state-of-the-art technologies being employedsuch as the combination of hydraulic fracturing and horizontal drilling.Actual future production, oil and natural gas prices, revenues, taxes, development expenditures, operating expenses and quantities of recoverable oiland natural gas reserves will vary from our estimates. Any significant variance could materially affect the estimated quantities and present value of reservesshown in this Annual Report on Form 10-K and our impairment charges. In addition, we may adjust estimates of proved reserves to reflect production history,results of exploration and development, prevailing oil and natural gas prices and other factors, many of which are beyond our control.The present value of future net revenues from our proved reserves will not necessarily be the same as the current market value of our estimated oil andnatural gas reserves.You should not assume that the present value of future net revenues from our proved reserves is the current market value of our estimated oil andnatural gas reserves. In accordance with SEC requirements for the years ended December 31, 2016, 2015 and 2014, we based the estimated discounted futurenet revenues from our proved reserves on the unweighted arithmetic average of the first-day-of-the-month commodity prices for the preceding twelve months(after adjustment for location and quality differentials), without giving effect to derivative transactions. Actual future net revenues from our oil and naturalgas properties will be affected by factors such as:•actual prices we receive for oil and natural gas and hedging instruments;•actual cost of development and production expenditures;•the amount and timing of actual production;•the amount and timing of future development costs;•wellbore productivity realizations above or below type curve forecast models;•the supply and demand of oil and natural gas; and•changes in governmental regulations or taxation.The timing of both our production and our incurrence of expenses in connection with the development and production of oil and natural gasproperties will affect the timing and amount of actual future net revenues from proved reserves, and thus40 Table of Contentstheir actual present value. In addition, the 10% discount factor (the factor required by the SEC) used when calculating discounted future net revenues maynot be the most appropriate discount factor based on interest rates in effect from time to time and risks associated with us or the oil and natural gas industry ingeneral.As a result of the sustained decrease in prices for oil, natural gas and NGLs, we have taken write-downs of the carrying value of our properties and may berequired to take further write-downs if oil and natural gas prices remain depressed or decline further or if we have substantial downward adjustments toour estimated proved reserves, increases in our estimates of development costs or deterioration in our drilling results.We review our proved oil and natural gas properties for impairment whenever events and circumstances indicate that a decline in the recoverabilityof their carrying value may have occurred. Based on specific market factors and circumstances at the time of prospective impairment reviews, and thecontinuing evaluation of development plans, production data, economics and other factors, from time to time, we may be required to write-down the carryingvalue of our oil and natural gas properties. A write-down constitutes a non-cash charge to earnings. Oil, natural gas and NGL prices have significantlydeclined since mid-2014 and have remained depressed through 2016. Due to a bid received while assets were held for sale, we recorded a $10.0 millionimpairment of oil and gas properties for the year ended December 31, 2016. Additionally, given the history of price volatility in the oil and natural gasmarkets, prices could remain depressed or decline further or other events may arise that would require us to record further impairments of the book valuesassociated with oil and natural gas properties. Accordingly, we may incur significant impairment charges in the future which could have a material adverseeffect on our results of operations and could reduce our earnings and stockholders’ equity for the periods in which such charges are taken.We intend to pursue the further development of our properties in the Wattenberg Field through horizontal drilling. Horizontal drilling operations can bemore operationally challenging and costly relative to our historic vertical drilling operations.Horizontal drilling is generally more complex and more expensive on a per well basis than vertical drilling. As a result, there is greater riskassociated with a horizontal well drilling program. Risks associated with our horizontal drilling program include, but are not limited to, the following, any ofwhich could materially and adversely impact the success of our horizontal drilling program and thus, our cash flows and results of operations:•landing our well bore in the desired drilling zone;•effectively controlling the level of pressure flowing from particular wells;•staying in the desired drilling zone while drilling horizontally through the formation;•running our casing the entire length of the wellbore;•running tools and other equipment consistently through the horizontal wellbore;•fracture stimulating the planned number of stages;•preventing downhole communications with other wells;•successfully cleaning out the well bore after completion of the final fracture stimulation stage; and•designing and maintaining efficient forms of artificial lift throughout the life of the well.Ultimately, the success of these drilling and completion techniques can only be evaluated over time as more wells are drilled and production profilesare established over a sufficiently long time period. If our drilling results are less than anticipated or we are unable to execute our drilling program because ofcapital constraints, lease expirations, access to gathering systems, limited takeaway capacity or depressed natural gas and oil prices, the return on ourinvestment in these areas may not be as attractive as anticipated. Further, as a result of any of these developments, we could incur material impairments of ouroil and gas properties and the value of our undeveloped acreage could decline in the future.Our ability to produce natural gas and oil economically and in commercial quantities could be impaired if we are unable to acquire adequate supplies ofwater for our drilling operations or are unable to dispose of or recycle the water we use at a reasonable cost and in accordance with applicableenvironmental rules.The hydraulic fracture stimulation process on which we depend to produce commercial quantities of oil and natural gas requires the use and disposalof significant quantities of water. Our inability to secure sufficient amounts of water (including as a result of droughts), or to dispose of or recycle the waterused in our operations, could adversely impact our operations. The imposition of new environmental initiatives and regulations could include restrictions onour ability to conduct41 Table of Contentscertain operations such as hydraulic fracturing or disposal of waste, including, but not limited to, produced water, drilling fluids and other wastes associatedwith the exploration, development or production of natural gas. Compliance with environmental regulations and permit requirements governing thewithdrawal, storage and use of surface water or groundwater necessary for hydraulic fracturing of wells may increase our operating costs and cause delays,interruptions or termination of our operations, the extent of which cannot be predicted, and all of which could have an adverse effect on our operations andfinancial condition.The unavailability or high cost of additional drilling rigs, equipment, supplies, personnel and oilfield services could adversely affect our ability to executeour exploration and development plans within our budget and on a timely basis.Shortages or the high cost of drilling rigs, equipment, supplies, personnel or oilfield services could delay or adversely affect our development andexploration operations or cause us to incur significant expenditures that are not provided for in our capital budget, which could have a material adverse effecton our business, financial condition or results of operations and may lead to reduced liquidity and the inability to pay our liabilities as they come due.Our exploration, development and exploitation projects require substantial capital expenditures. We may be unable to obtain needed capital or financingon satisfactory terms, which could lead to expiration of our leases or a decline in our oil and natural gas reserves or anticipated production volumes.Our exploration, development and exploitation activities are capital intensive. We make and expect to continue to make substantial capitalexpenditures in our business for the development, exploitation, production and acquisition of oil and natural gas reserves. Until such time as we obtainconfirmation of a plan of reorganization in our bankruptcy proceeding and enter into a new revolving credit facility or obtain a different, comparable sourceof liquidity, there can be no assurance that we will have sufficient capital to meet these needs Without sufficient capital, we may face a further curtailment ofour operations relating to development of our drilling locations, which in turn could lead to a possible expiration of our undeveloped leases and a decline inour oil and natural gas reserves, and an adverse effect on our business, financial condition and results of operations.Increased costs of capital could adversely affect our business.Recent and continuing disruptions and volatility in the global financial markets may lead to an increase in interest rates or a contraction in creditavailability, impacting our ability to finance our operations. Our business and operating results can be harmed by factors such as the terms and cost of capital,increases in interest rates or a reduction in credit rating. Changes in any one or more of these factors could cause our cost of doing business to increase, limitour access to capital, limit our ability to pursue acquisition opportunities, reduce our cash flows available for drilling, render us unable to replace reservesand production and place us at a competitive disadvantage.Concentration of our operations in a few core areas may increase our risk of production loss.Our assets and operations are concentrated in two core areas: the Wattenberg Field in Colorado and the Dorcheat Macedonia Field in southernArkansas. These core areas currently provide approximately 99% of our current sales volumes and the vast majority of our development projects.The Wattenberg and Dorcheat Macedonia Fields represent 81% and 19%, respectively, of our 2016 total sales volumes. Because our operations arenot as diversified geographically as some of our competitors, the success of our operations and our profitability may be disproportionately exposed to theeffect of any regional events, including: fluctuations in prices of crude oil, natural gas and NGLs produced from wells in the area, accidents or naturaldisasters, restrictive governmental regulations and curtailment of production or interruption in the availability of gathering, processing or transportationinfrastructure and services, and any resulting delays or interruptions of production from existing or planned new wells. Similarly, the concentration of ourassets within a small number of producing formations exposes us to risks, such as changes in field-wide rules, which could adversely affect developmentactivities or production relating to those formations. In addition, in areas where exploration and production activities are increasing, as has been the case inrecent years in the Wattenberg Field, we are subject to increasing competition for drilling rigs, oilfield equipment, services, supplies and qualified personnel,which may lead to periodic shortages or delays. These constraints and the resulting shortages or high costs could delay our operations and materially increaseour operating and capital costs.We do not maintain business interruption (loss of production) insurance for our oil and gas producing properties. Loss of production or limitedaccess to reserves in either of our core operating areas could have a significant negative impact on our cash flows and profitability.42 Table of ContentsWe have limited control over activities on properties in which we own an interest but we do not operate, which could reduce our production and revenues.We do not operate all of the properties in which we have an interest. As a result, we may have a limited ability to exercise influence over normaloperating procedures, expenditures or future development of underlying properties and their associated costs. For all of the properties that are operated byothers, we are dependent on their decision-making with respect to day-to-day operations over which we have little control. The failure of an operator of wellsin which we have an interest to adequately perform operations, or an operator’s breach of applicable agreements, could reduce production and revenues wereceive from that well. The success and timing of our drilling and development activities on properties operated by others depend upon a number of factorsoutside of our control, including the timing and amount of capital expenditures, the available expertise and financial resources, the inclusion of otherparticipants and the use of technology. Our lack of control over non-operated properties also makes it more difficult for us to forecast capital expenditures,revenues, production and related matters.We are dependent on third party pipeline, trucking and rail systems to transport our production and, in the Wattenberg Field, gathering and processingsystems to prepare our production. These systems have limited capacity and at times have experienced service disruptions. Curtailments, disruptions orlack of availability in these systems interfere with our ability to market the oil and natural gas we produce, and could materially and adversely affect ourcash flow and results of operations.Market conditions or the unavailability of satisfactory oil and natural gas transportation arrangements may hinder our access to oil and natural gasmarkets or delay our production getting to market. The marketability of our oil and natural gas and production, particularly from our wells located in theWattenberg Field, depends in part on the availability, proximity and capacity of gathering, processing, pipeline, trucking and rail systems. The amount of oiland natural gas that can be produced and sold is subject to limitation in certain circumstances, such as pipeline interruptions due to scheduled andunscheduled maintenance, excessive pressure, physical damage to the gathering or transportation system, or lack of contracted capacity on such systems. Aportion of our production may also be interrupted, or shut in, from time to time for numerous other reasons, including as a result of accidents, maintenance,weather, field labor issues or disruptions in service. Curtailments and disruptions in these systems may last from a few days to several months. Any significantcurtailment in gathering, processing or pipeline system capacity, significant delay in the construction of necessary facilities or lack of availability oftransport, would interfere with our ability to market the oil and natural gas we produce, and could materially and adversely affect our cash flow and results ofoperations, and the expected results of our drilling program.Currently, there are no natural gas pipeline systems that service wells in the North Park Basin, which is prospective for the Niobrara formation. Inaddition, we are not aware of any plans to construct a facility necessary to process natural gas produced from this basin. If neither we nor a third partyconstructs the required pipeline system and processing facility, we may not be able to fully develop our resources in the North Park Basin.The development of our proved undeveloped reserves may take longer and may require higher levels of capital expenditures than we currently anticipate.Therefore, our undeveloped reserves may not be ultimately developed or produced.Approximately 44% of our total proved reserves were classified as proved undeveloped as of December 31, 2016. Development of these reservesmay take longer and require higher levels of capital expenditures than we currently anticipate or that may be available to us. Delays in the development ofour reserves or increases in costs to drill and develop such reserves will reduce the value of our estimated proved undeveloped reserves and future netrevenues estimated for such reserves and may result in some projects becoming uneconomic. In addition, delays in the development of reserves could causeus to have to reclassify our proved reserves as unproved reserves.Unless we replace our oil and natural gas reserves, our reserves and production will decline, which would adversely affect our business, financial conditionand results of operations.In general, production from oil and gas properties declines as reserves are depleted, with the rate of decline depending on reservoir characteristics.Our current proved reserves will decline as reserves are produced and, therefore, our level of production and cash flows will be affected adversely unless weconduct successful exploration and development activities or acquire properties containing proved reserves. Thus, our future oil and natural gas productionand, therefore, our cash flow and income are highly dependent upon our level of success in finding or acquiring additional reserves. However, we cannotassure you that our future acquisition, development and exploration activities will result in any specific amount of additional proved reserves or that we willbe able to drill productive wells at acceptable costs.43 Table of ContentsWe may incur substantial losses and be subject to substantial liability claims as a result of our oil and natural gas operations. Additionally, we may not beinsured for, or our insurance may be inadequate to protect us against, these risks, including those related to our hydraulic fracturing operations.Our oil and natural gas exploration and production activities are subject to all of the operating risks associated with drilling for and producing oiland natural gas, including, but not limited to, the possibility of:•environmental hazards, such as spills, uncontrollable flows of oil, natural gas, brine, well fluids, natural gas, hazardous air pollutants or otherpollution into the environment, including groundwater and shoreline contamination;•releases of natural gas and hazardous air pollutants or other substances into the atmosphere (including releases at our gas processing facilities);•hazards resulting from the presence of hydrogen sulfide (H2S) or other contaminants in natural gas we produce;•abnormally pressured formations resulting in well blowouts, fires or explosions;•mechanical difficulties, such as stuck oilfield drilling and service tools and casing collapse;•cratering (catastrophic failure);•downhole communication leading to migration of contaminants;•personal injuries and death; and•natural disasters.Any of these risks could adversely affect our ability to conduct operations or result in substantial losses to us as a result of:•injury or loss of life;•damage to and destruction of property, natural resources and equipment;•pollution and other environmental damage;•regulatory investigations and penalties;•suspension of our operations; and•repair and remediation costs.The presence of H2S, a toxic, flammable and colorless gas, is a common risk in the oil and gas industry and may be present in small amounts for briefperiods from time to time at our well locations. Additionally, at one of our Arkansas properties, we produce a small amount of gas from four wells where wehave identified the presence of H2S at levels that would be hazardous in the event of an uncontrolled gas release or unprotected exposure. In addition, ouroperations in Arkansas and Colorado are susceptible to damage from natural disasters such as flooding, wildfires or tornados, which involve increased risks ofpersonal injury, property damage and marketing interruptions. The occurrence of one of these operating hazards may result in injury, loss of life, suspensionof operations, environmental damage and remediation and/or governmental investigations and penalties. The payment of any of these liabilities couldreduce, or even eliminate, the funds available for exploration and development, or could result in a loss of our properties.As is customary in the oil and gas industry, we maintain insurance against some, but not all, of these potential risks and losses. Although we believethe coverage and amounts of insurance that we carry are consistent with industry practice, we do not have insurance protection against all risks that we face,because we choose not to insure certain risks, insurance is not available at a level that balances the costs of insurance and our desired rates of return, or actuallosses exceed coverage limits. Insurance costs will likely continue to increase which could result in our determination to decrease coverage and retain morerisk to mitigate those cost increases. In addition, pollution and environmental risks generally are not fully insurable. If we incur substantial liability, and thedamages are not covered by insurance or are in excess of policy limits, then our business, results of operations and financial condition may be materiallyadversely affected.Because hydraulic fracturing activities are part of our operations, they are covered by our insurance against claims made for bodily injury, propertydamage and clean-up costs stemming from a sudden and accidental pollution event. However,44 Table of Contentswe may not have coverage if the operator is unaware of the pollution event and unable to report the “occurrence” to the insurance company within therequired time frame. We also do not have coverage for gradual, long-term pollution events.Under certain circumstances, we have agreed to indemnify third parties against losses resulting from our operations. Pursuant to our surface leases,we typically indemnify the surface owner for clean-up and remediation of the site. As owner and operator of oil and gas wells and associated gatheringsystems and pipelines, we typically indemnify the drilling contractor for pollution emanating from the well, while the contractor indemnifies us againstpollution emanating from its equipment.Drilling locations that we decide to drill may not yield oil or natural gas in commercially viable quantities.We describe some of our drilling locations and our plans to explore those drilling locations in this Annual Report on Form 10-K. Our drillinglocations are in various stages of evaluation, ranging from a location that is ready to drill to a location that will require substantial additional evaluation.There is no way to predict in advance of drilling and testing whether any particular location will yield oil or natural gas in sufficient quantities to recoverdrilling or completion costs or to be economically viable. Prior to drilling, the use of 2-D and 3-D seismic technologies, various other technologies and thestudy of producing fields in the same area will not enable us to know conclusively whether oil or natural gas will be present or, if present, whether oil ornatural gas will be present in sufficient quantities to be economically viable. In addition, the use of 2-D and 3-D seismic data and other technologies requiresgreater pre-drilling expenditures than traditional drilling strategies, and we could incur greater drilling and testing expenses as a result of such expenditureswhich may result in a reduction in our returns or increase our losses. Even if sufficient amounts of oil or natural gas exist, we may damage the potentiallyproductive hydrocarbon bearing formation or experience mechanical difficulties while drilling or completing the well, resulting in a reduction in productionfrom the well or abandonment of the well. If we drill any dry holes in our current and future drilling locations, our profitability and the value of our propertieswill likely be reduced. We cannot assure you that the analogies we draw from available data from other wells, more fully explored locations or producingfields will be applicable to our drilling locations. Further, initial production rates reported by us or other operators may not be indicative of future or long-term production rates. In sum, the cost of drilling, completing and operating any well is often uncertain, and new wells may not be productive.Our potential drilling locations are scheduled to be developed over several years, making them susceptible to uncertainties that could materially alter theoccurrence or timing of their drilling. In addition, we may not be able to raise the substantial amount of capital that would be necessary to drill asubstantial portion of our potential drilling locations.Our management has identified and scheduled drilling locations as an estimation of our future multi-year drilling activities on our existing acreage.These potential drilling locations, including those without proved undeveloped reserves, represent a significant part of our growth strategy. Our ability todrill and develop these locations is subject to a number of uncertainties, including uncertainty in the level of reserves, the availability of capital to us andother participants, seasonal conditions, regulatory approvals, oil, natural gas and NGL prices, availability of permits, costs and drilling results. Because ofthese uncertainties, we do not know if the numerous potential drilling locations we have identified will ever be drilled or if we will be able to produce oil ornatural gas from these or any other potential drilling locations. Pursuant to existing SEC rules and guidance, subject to limited exceptions, provedundeveloped reserves may only be booked if they relate to wells scheduled to be drilled within five years of the date of booking, and we may therefore berequired to downgrade to probable or possible any proved undeveloped reserves that are not developed within this five-year time frame. These limitationsmay limit our potential to book additional proved undeveloped reserves as we pursue our drilling program.Certain of our undeveloped leasehold acreage is subject to leases that will expire over the next several years unless production is established on unitscontaining the acreage.The terms of our oil and gas leases stipulate that the lease will terminate if not held by production, rentals, or production. As of the filing date of thisreport, the majority of our acreage in Arkansas was held by unitization, production, or drilling operations and therefore not subject to lease expiration. As ofthe filing date of this report, approximately 9,341 net acres of our properties in the Rocky Mountain region were not held by production. For these properties,if production in paying quantities is not established on units containing these leases during the next year, then approximately 4,809 net acres will expire in2017, approximately 4,079 net acres will expire in 2018, and approximately 453 net acres will expire in 2019 and thereafter. While some expiring leases maycontain predetermined extension payments, other expiring leases will require us to negotiate new leases at the time of lease expiration. It is possible thatmarket conditions at the time of negotiation could require us to agree to new leases on less favorable terms to us than the terms of the expired leases. If ourleases expire, we will lose our right to develop the related properties.45 Table of ContentsWe may incur losses as a result of title deficiencies.The existence of a title deficiency can diminish the value of an acquired leasehold interest and can adversely affect our results of operations andfinancial condition. Title insurance covering mineral leasehold interests is not generally available. As is industry standard, we may rely upon a landprofessional’s careful examination of public records prior to purchasing or leasing a mineral interest. Once a mineral or leasehold interest has been acquired,we typically defer the expense of obtaining further title verification by a practicing title attorney until approval to drill the related drilling block is required.We perform the necessary curative work to correct deficiencies in the marketability of the title and we have compliance and control measures to ensure anyassociated business risk is approved by the appropriate Company authority. In cases involving more serious title deficiencies, all or part of a mineral orleasehold interest may be determined to be invalid or unleased, and, as a result, the target area may be deemed to be undrillable until owners can be contactedand curative measures performed to perfect title. In other cases, title deficiencies may result in our failure to have paid royalty owners correctly. Certain titledeficiencies may also result in litigation to effectively agree or render a decision upon title ownership. Additional title issues are present in some of oursouthern Arkansas operations where significant delays in the title examination process are possible due to, among other challenges, the large volume ofinstruments contained in abstracts, poor indexing at the county clerk and recorder’s office, unrecorded conveyances, misfiling of instruments, instrumentswith missing or inadequate legal descriptions and unclear conveyance terms.We face various risks associated with the trend toward increased activism against oil and gas exploration and development activities.Opposition toward oil and gas drilling and development activity has been growing globally and is particularly pronounced in the United States.Companies in the oil and gas industry are often the target of activist efforts from both individuals and non-governmental organizations regarding safety,environmental compliance and business practices. Anti-development activists are working to, among other things, reduce access to federal and stategovernment lands and delay or cancel certain projects such as the development of oil or gas shale plays. For example, environmental activists continue toadvocate for increased regulations or bans on shale drilling in the United States, even in jurisdictions that are among the most stringent in their regulation ofthe industry. In fact, New York State enacted a permanent moratorium on all hydraulic fracturing operations, which became final in June 2015. Future activistefforts could result in the following:•delay or denial of drilling permits;•shortening of lease terms or reduction in lease size;•restrictions on installation or operation of production, gathering or processing facilities;•restrictions on the use of certain operating practices, such as hydraulic fracturing, or the disposal of related waste materials, such as hydraulicfracturing fluids and produced water;•increased severance and/or other taxes;•cyber-attacks;•legal challenges or lawsuits;•negative publicity about us or the oil and gas industry in general;•increased costs of doing business;•reduction in demand for our products; and•other adverse effects on our ability to develop our properties and expand production.We may need to incur significant costs associated with responding to these initiatives. Complying with any resulting additional legal or regulatoryrequirements that are substantial could have a material adverse effect on our business, financial condition and results of operations.We are subject to health, safety and environmental laws and regulations that may expose us to significant costs and liabilities.We are subject to stringent and complex federal, state and local laws and regulations governing health and safety aspects of our operations, thedischarge of materials into the environment and the protection of the environment. These laws and regulations may impose on our operations numerousrequirements, including the obligation to obtain a permit before46 Table of Contentsconducting drilling or underground injection activities; restrictions on the types, quantities and concentration of materials that may be released into theenvironment; limitations or prohibitions of drilling activities that impact threatened or endangered species or that occur on certain lands lying withinwilderness, wetlands and other protected areas; the application of specific health and safety criteria to protect workers; and the responsibility for cleaning upany pollution resulting from operations. Numerous governmental authorities, such as the EPA and analogous state agencies, have the power to enforcecompliance with these laws and regulations and the permits issued under them, oftentimes requiring difficult and costly actions. Failure to comply with theselaws and regulations may result in the assessment of administrative, civil and criminal penalties; the imposition of investigatory or remedial obligations; theissuance of injunctions limiting or preventing some or all of our operations; delays in granting permits, or even the cancellation of leases.There is an inherent risk of incurring significant environmental costs and liabilities in the performance of our operations, some of which may bematerial, due to our handling of petroleum hydrocarbons and wastes, our emissions into air and water, the underground injection or other disposal of ourwastes, the use and disposition of hydraulic fracturing fluids, and historical industry operations and waste disposal practices. Under certain environmentallaws and regulations, we may be liable for the full cost of removing or remediating contamination, regardless of whether we were at fault, and even whenmultiple parties contributed to the release and the contaminants were released in compliance with all applicable laws. In addition, accidental spills or releaseson our properties may expose us to significant liabilities that could have a material adverse effect on our financial condition or results of operations. Asidefrom government agencies, the owners of properties where our wells are located, the owners or operators of facilities where our petroleum hydrocarbons orwastes are taken for reclamation or disposal, and other private parties may be able to sue us to enforce compliance with environmental laws and regulations,collect penalties for violations, or obtain damages for any related personal injury, property, or natural resource damage. Some sites we operate are locatednear current or former third-party oil and natural gas operations or facilities, and there is a risk that historic contamination has migrated from those sites toours. Changes in environmental laws and regulations occur frequently, and any changes that result in more stringent or costly requirements could require usto make significant expenditures to attain and maintain compliance or may otherwise have a material adverse effect on our own results of operations,competitive position or financial condition. We may not be able to recover some or any of these costs from insurance.New environmental legislation or regulatory initiatives, including those related to hydraulic fracturing, could result in increased costs and additionaloperating restrictions or delays.We are subject to extensive federal, state, and local laws and regulations concerning health, safety, and environmental protection. Governmentalauthorities frequently add to those requirements, and both oil and gas development generally, and hydraulic fracturing specifically, are receiving increasingregulatory attention. Our operations utilize hydraulic fracturing, an important and commonly used process in the completion of oil and natural gas wells inlow-permeability formations. Hydraulic fracturing involves the injection of water, proppant, and chemicals under pressure into rock formations to stimulatehydrocarbon production.In August 2012, the EPA issued final NSPS (known as “Quad O”) that establish new air emission controls for natural gas processing operations, aswell as for oil and natural gas production. Among other things, Quad O imposes reduced emission completion (or “green completion”) requirements and alsoimposes stringent control and other standards on certain storage tanks, compressors and associated equipment. After several parties challenged the Quad Oregulations in court, the EPA administratively reconsidered certain requirements. As a result of such administrative reconsideration, the EPA issued finalamendments to the Quad O regulations in September 2013 and December 2014. In May 2016, the EPA finalized amendments to Quad O, now called Quad Oa,focused on achieving additional reductions in methane and volatile organic compound emissions at oil and natural gas operations. These rules, among otherthings, require leak detection and repair, additional control requirements for pneumatic controllers and pumps, and additional control requirements for oilwell completions, gathering, boosting, and compressor stations. At this point, we cannot predict the cost to comply with such air regulatory requirements.On December 17, 2014, the EPA proposed to revise and lower the existing 75 ppb NAAQS for ozone under the federal Clean Air Act to a rangewithin 65-70 ppb. On October 1, 2015, EPA finalized a rule lowering the standard to 70 ppb. This lowered ozone NAAQS could result in an expansion ofozone nonattainment areas across the United States, including areas in which we operate. In a related development, in 2015 the State of Colorado received abump-up to its existing ozone non-attainment status from “marginal” to “moderate.” This increased status will result in additional requirements under theCAA for the State of Colorado and will include a state rulemaking to implement such requirements. This rulemaking process started in early 2017. Oil andnatural gas operations in ozone nonattainment areas may be subject to increased regulatory burdens in the form of more stringent emission controls, emissionoffset requirements, and increased permitting delays and costs.In February 2014, the Colorado Department of Public Health and Environment’s Air Quality Control Commission finalized regulations imposingstrict new requirements relating to air emissions from oil and gas facilities in Colorado that are47 Table of Contentseven more stringent than comparable federal rules. These new Colorado rules include storage tank control, monitoring, recordkeeping and reportingrequirements as well as leak detection and repair requirements for both well production facilities and compressor stations and associated equipment. Thesenew requirements, which represent the first time a state has directly regulated methane (a greenhouse gas) emissions from the upstream oil and gas sector,have and will continue to impose additional costs on our operations.Some activists have attempted to link hydraulic fracturing to various environmental problems, including potential adverse effects to drinking watersupplies as well as migration of methane and other hydrocarbons and increased earthquakes. The federal government is studying the environmental risksassociated with hydraulic fracturing and evaluating whether to adopt additional regulatory requirements. For example, the EPA has commenced a multi-yearstudy of the potential impacts of hydraulic fracturing on drinking water resources. A draft assessment was published for public comment in 2015. Theassessment concludes that while there are mechanisms by which hydraulic fracturing can impact drinking water resources, there was no evidence that thesemechanisms have led to widespread, systemic impacts on drinking water resources in the United States. EPA’s science advisory board, however, hassubsequently questioned several elements and conclusions in EPA’s draft assessment. In addition, in 2011, the EPA announced its intention to proposeregulations under the federal Clean Water Act to regulate wastewater discharges from hydraulic fracturing and other natural gas production. EPA publishedthese proposed rules in early 2015. The EPA also has issued guidance for issuing underground injection permits for hydraulic fracturing operations that usediesel fuel under the agency’s SDWA authority.In the United States Congress, bills have been introduced that would amend the SDWA to eliminate an existing exemption for certain hydraulicfracturing activities from the definition of “underground injection,” thereby requiring the oil and natural gas industry to obtain SDWA permits for fracturingnot involving diesel fuels, and to require disclosure of the chemicals used in the process. If adopted, such legislation could establish an additional level ofregulation and permitting at the federal level, but some form of chemical disclosure is already required by most oil and gas producing states. At this time, it isnot clear what action, if any, the United States Congress will take on this exemption.Moreover, the U.S. Department of the Interior finalized new rules for hydraulic fracturing activities on federal lands that, in general, would coverdisclosure of fracturing fluid components, well bore integrity, and handling of flowback water. The rule, while final, has been stayed pending the outcome ofongoing litigation. The BLM also proposed rules to address venting and flaring on BLM land, which the U.S. House of Representatives has passed a bill torepeal, and the U.S. Occupational Safety and Health Administration has proposed stricter standards for worker exposure to silica, which would apply to use ofsand as a proppant for hydraulic fracturing.Apart from these ongoing federal initiatives, state governments where we operate have moved to impose stricter requirements on hydraulic fracturingand other aspects of oil and gas production. Colorado, for example, comprehensively updated its oil and gas regulations in 2008 and adopted significantadditional amendments in 2011, 2014 and 2015. Among other things, the updated and amended regulations require operators to reduce methane emissionsassociated with hydraulic fracturing, compile and report additional information regarding well bore integrity, publicly disclose the chemical ingredients usedin hydraulic fracturing, increase the minimum distance between occupied structures and oil and gas wells, undertake additional mitigation for nearbyresidents, implement additional groundwater testing and incur increased monetary penalties for violations of the State’s oil and gas conservation commissionrules and regulations. Similarly, in February 2015, a task force created by the State of Colorado aimed at making recommendations for minimizing land useand other conflicts concerning the location of new oil and gas facilities agreed upon nine consensus proposals which were sent to Governor Hickenlooper forhis review. Three of the proposals require further legislative action, while the other six proposals require rulemaking or other regulatory action. Theproposals support (i) a senate bill that would postpone expiration of recently adopted regulations regarding air emissions; (ii) tasking the COGCC withcrafting new rules related to siting of “large-scale” pads and facilities; (iii) requiring the industry to provide advance information about development plans tolocal governments; (iv) improving the COGCC’s local government liaison and designee programs; (v) adding 11 full-time staffers to the COGCC to improveinspections and field operations; (vi) bolstering the inspection staff and equipment for monitoring oil and gas facility air emissions and setting up a hotlinefor citizen health complaints at the Colorado Department of Public Health and Environment; (vii) creating a statewide oil and gas information clearinghouse;(viii) studying ways to ameliorate the impact of oil and gas truck traffic and (ix) creating a compliance-assistance program at the COGCC to help operatorscomply with the state's changing rules and ensure consistent enforcement of rules by state inspectors. A number of additional proposals did not receivesufficient task force support to be included with the nine consensus proposals, but may nevertheless be forwarded to the Governor as well. In early 2016,COGCC finalized a rulemaking to implement two of the nine recommendations noted above (numbers (ii) and (iii) specifically). With regard torecommendation (ii), the COGCC finalized rules applicable to the permitting of large-scale facilities in urban mitigation areas. For recommendation (iii), theCOGCC finalized rules requiring operators to provide certain municipalities with notice prior to engaging in certain operations.48 Table of ContentsIn some instances certain local governments are adopting new requirements on hydraulic fracturing and other oil and gas operations. Some countiesin Colorado, for instance, have amended their land use regulations to impose new requirements on oil and gas development, while other local governmentshave entered memoranda of agreement with oil and gas producers to accomplish the same objective. In addition, voters in Colorado have proposed oradvanced ballot initiatives restricting or banning oil and gas development in Colorado. Because a substantial portion of our operations and reserves arelocated in Colorado, the risks we face with respect to such ballot initiatives are greater than other companies with more geographically diverse operations.The adoption of future federal, state or local laws or implementing regulations imposing new environmental obligations on, or otherwise limiting, ouroperations could make it more difficult and more expensive to complete oil and natural gas wells, increase our costs of compliance and doing business, delayor prevent the development of certain resources (including especially shale formations that are not commercial without the use of hydraulic fracturing), oralter the demand for and consumption of our products and services. We cannot assure you that any such outcome would not be material, and any suchoutcome could have a material adverse impact on our cash flows and results of operations.Climate change laws and regulations restricting emissions of “greenhouse gases” could result in increased operating costs and reduced demand for the oiland natural gas that we produce, while the physical effects of climate change could disrupt our production and cause us to incur significant costs inpreparing for or responding to those effects.There is a growing belief that human-caused (anthropogenic) emissions of GHGs may be linked to climate change. Climate change and the costs thatmay be associated with its impacts and the regulation of GHGs have the potential to affect our business in many ways, including negatively impacting thecosts we incur in providing our products and services and the demand for and consumption of our products and services (due to potential changes in bothcosts and weather patterns).In December 2009, the EPA determined that atmospheric concentrations of carbon dioxide, methane and certain other GHGs present anendangerment to public health and welfare, because such gases are, according to the EPA, contributing to the warming of the earth’s atmosphere and otherclimatic changes. Consistent with its findings, the EPA has proposed or adopted various regulations under the Clean Air Act to address GHGs. Among otherthings, the EPA began limiting emissions of GHGs from new cars and light duty trucks beginning with the 2012 model year. In addition, in 2010 the EPApublished a final rule to address the permitting of GHG emissions from stationary sources under the Prevention of Significant Deterioration, or “PSD,” andTitle V permitting programs. Under this rule, the EPA imposed certain GHG permitting requirements on the largest major sources first. As noted above, inJune 2014, the United States Supreme Court invalidated part of the EPA’s stationary source GHG program in Utility Air Regulatory Group v. EPA, No. 12-1146. Specifically, the Supreme Court ruled that major sources subject to the PSD or Title V programs because of non-GHG emissions could potentially bestill subject to certain “best available control technology” requirements applicable to their GHG emissions. Under the Supreme Court’s opinion, sourcessubject to the PSD or Title V programs due solely to their GHG emissions can no longer be subject to the EPA’s GHG permitting requirements. The D.C.Circuit issued an amended judgment following remand, and the EPA intends to conduct future rulemaking to revise its GHG major stationary sourcepermitting program to conform to the court rulings. In a related development, in May 2016, the EPA finalized a rule to further define “adjacency” under theCAA for purposes of determining and permitting major stationary sources, including GHG major sources.The EPA also adopted regulations requiring the reporting of GHG emissions from specific categories of higher GHG emitting sources in the UnitedStates, including certain oil and natural gas production facilities, which include certain of our operations, beginning in 2012 for emissions occurring in 2011.Information in such report may form the basis for further GHG regulation. Further, the EPA has continued with its comprehensive strategy for further reducingmethane emissions from oil and gas operations, with a final rule being issued In May 2016 as part of the 2012 Quad O reconsideration known as “Quad Oa.”The EPA’s GHG rules could adversely affect our operations and restrict or delay our ability to obtain air permits for new or modified facilities.Moreover, Congress has from time to time considered adopting legislation to reduce emissions of GHGs or promote the use of renewable fuels. As analternative, some proponents of GHG controls have advocated mandating a national “clean energy” standard. The EPA recently finalized rules for both newand existing power plants known as the “Clean Power Plan” designed to decrease GHG emissions from these sources. We are unable to predict how, or if, theClean Power Plan will affect our operations. In addition, the United States reached agreement during the December 2015 United Nations climate changeconference to reduce its GHG emissions by 26-28% by 2025 compared with 2005 levels, and also to provide periodic updates on its progress.In the meantime, many states already have taken such measures, which have included renewable energy standards, development of GHG emissioninventories or cap and trade programs. Cap and trade programs typically work by requiring major sources of emissions or major producers of fuels to acquireand surrender emission allowances, with the number of available allowances reduced each year until the overall GHG emission reduction goal is achieved.These allowances would be expected to escalate significantly in cost over time.49 Table of ContentsThe adoption of legislation or regulatory programs to reduce emissions of GHGs could require us to incur increased operating costs, such as costs topurchase and operate emissions control systems, to acquire emissions allowances or comply with new regulatory or reporting requirements. If we are unable torecover or pass through a significant level of our costs related to complying with climate change regulatory requirements imposed on us, it could have amaterial adverse effect on our results of operations and financial condition. Any such legislation or regulatory programs could also increase the cost ofconsuming, and thereby reduce demand for, the oil and natural gas we produce. Consequently, legislation and regulatory programs to reduce emissions ofGHGs could have an adverse effect on our business, financial condition and results of operations.Competition in the oil and natural gas industry is intense, making it more difficult for us to acquire properties, market oil and natural gas and securetrained personnel.Our ability to acquire additional drilling locations and to find and develop reserves in the future will depend heavily on our financial resources andability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment for acquiring properties, marketing oiland natural gas and securing equipment and trained personnel. Also, there is substantial competition for capital available for investment in the oil and naturalgas industry. Many of our competitors possess and employ financial, technical and personnel resources substantially greater than ours. Those companies maybe able to pay more for productive oil and natural gas properties and exploratory drilling locations or to identify, evaluate, bid for and purchase a greaternumber of properties and locations than our financial or personnel resources permit. Furthermore, these companies may also be better able to withstandunsuccessful drilling attempts, sustained periods of volatility in financial markets and generally adverse global and industry-wide economic conditions, andmay be better able to absorb the burdens resulting from changes in relevant laws and regulations, which would adversely affect our competitive position. Inaddition, companies may be able to offer better compensation packages to attract and retain qualified personnel than we are able to offer. We may not be ableto compete successfully in the future in acquiring prospective reserves, developing reserves, marketing hydrocarbons, attracting and retaining qualitypersonnel and raising additional capital, which could have a material adverse effect on our business.If we fail to retain our existing senior management or technical personnel or attract qualified new personnel, such failure could adversely affect ouroperations. The volatility in commodity prices and business performance may affect our ability to retain senior management and the loss of these keyemployees may affect our business, financial condition and results of operations.To a large extent, we depend on the services of our senior management and technical personnel. The loss of the services of our senior management,technical personnel, or any of the vice presidents of the Company, could have a material adverse effect on our operations or strategy. The volatility incommodity prices and our business performance may affect our ability to incentivize and retain senior management or key employees. Our currentbankruptcy proceeding also has significant potential to adversely affect our ability to retain senior management and key employees. Competition forexperienced senior management, technical and other professional personnel remains strong. If we cannot retain our current personnel or attract additionalexperienced personnel, our ability to compete could be adversely affected. Also, the loss of experienced personnel could lead to a loss of technical expertise.We do not maintain, nor do we plan to obtain, any insurance against the loss of any of these individuals.Our derivative activities could result in financial losses or could reduce our income.To achieve more predictable cash flows and to reduce our exposure to adverse fluctuations in the prices of oil and natural gas, we may in the futureenter into derivative arrangements for a portion of our oil and natural gas production, including collars and fixed-price swaps. We have not in the pastdesignated any of our derivative instruments as hedges for accounting purposes and have recorded all derivative instruments on our balance sheet at fairvalue. Changes in the fair value of our derivative instruments are recognized in earnings. Accordingly, our earnings may fluctuate significantly as a result ofchanges in the fair value of our derivative instruments.Derivative arrangements also expose us to the risk of financial loss in some circumstances, including when:•production is less than the volume covered by the derivative instruments;•the counterparty to the derivative instrument defaults on its contract obligations; or•there is an increase in the differential between the underlying price in the derivative instrument and actual prices received.50 Table of ContentsIn addition, these types of derivative arrangements may limit the benefit we would receive from increases in the prices for oil and natural gas andmay expose us to cash margin requirements.We are exposed to credit risks of our hedging counterparties, third parties participating in our wells and our customers.Our principal exposures to credit risk are through receivables resulting from commodity derivatives instruments, which were zero at December 31, 2016(but would increase if we resume a hedging program), joint interest and other receivables of $6.8 million at December 31, 2016 and the sale of our oil, naturalgas and NGLs production of $14.5 million in receivables at December 31, 2016, which we market to energy marketing companies, refineries and affiliates.Joint interest receivables arise from billing entities who own partial interest in the wells we operate. These entities participate in our wells primarilybased on their ownership in leases on which we wish to drill. We can do very little to choose who participates in our wells.We are also subject to credit risk due to concentration of our oil, natural gas and NGLs receivables with significant customers. This concentration ofcustomers may impact our overall credit risk since these entities may be similarly affected by changes in economic and other conditions. For the year endedDecember 31, 2016, sales to Silo Energy, LLC, Lion Oil Trading & Transport, Inc., and Duke Energy Field Services accounted for approximately 50%, 18%and 14%, respectively, of our total sales. Beginning in 2017 and continuing for seven years, we have contracted to sell all of our crude oil produced for a one-rig program in the Wattenberg Field to NGL Crude Logistics, LLC.We are exposed to credit risk in the event of default of our counterparty, principally with respect to hedging agreements but also insurance contracts andbank lending commitments. We do not require most of our customers to post collateral. The inability or failure of our significant customers to meet theirobligations to us or their insolvency or liquidation may adversely affect our financial results. Deterioration in the credit markets may impact the creditratings of our current and potential counterparties and affect their ability to fulfill their existing obligations to us and their willingness to enter into futuretransactions with us.Current or proposed financial legislation and rulemaking could have an adverse effect on our ability to use derivative instruments to reduce the effect ofcommodity price, interest rate and other risks associated with our business.The Dodd-Frank Act establishes, among other provisions, federal oversight and regulation of the over-the-counter derivatives market and entitiesthat participate in that market. The Dodd-Frank Act also establishes margin requirements and certain transaction clearing and trade execution requirements.The Dodd-Frank Act may require us to comply with margin requirements in our derivative activities, although the application of those provisions to us isuncertain at this time. The financial reform legislation may also require the counterparties to our derivative instruments to spin off some of their derivativesactivities to separate entities, which may not be as creditworthy as the current counterparties.The Dodd-Frank Act and any new regulations could significantly increase the cost of derivative contracts (including through requirements to postcollateral, which could adversely affect our available liquidity), materially alter the terms of derivative contracts, reduce the availability of derivatives toprotect against risks we encounter, reduce our ability to monetize or restructure our existing derivative contracts and increase our exposure to lesscreditworthy counterparties. If we reduce our use of derivative as a result of the Dodd-Frank Act and regulations, our results of operations may be morevolatile and our cash flows may be less predictable, which could adversely affect our ability to plan for and fund capital expenditures.We may be involved in legal cases that may result in substantial liabilities.Like many oil and gas companies, we are from time to time involved in various legal and other cases, such as title, royalty or contractual disputes,regulatory compliance matters and personal injury or property damage matters, in the ordinary course of our business. Such legal cases are inherentlyuncertain and their results cannot be predicted. Regardless of the outcome, such cases could have an adverse impact on us because of legal costs, diversion ofmanagement and other personnel and other factors. In addition, it is possible that a resolution of one or more such cases could result in liability, penalties orsanctions, as well as judgments, consent decrees or orders requiring a change in our business practices, which could materially and adversely affect ourbusiness, operating results and financial condition. Accruals for such liability, penalties or sanctions may be insufficient. Judgments and estimates todetermine accruals or range of losses related to legal and other cases could change from one period to the next, and such changes could be material.51 Table of ContentsWe are subject to federal, state, and local taxes, and may become subject to new taxes and certain federal income tax deductions currently available withrespect to oil and gas exploration and development may be eliminated as a result of future legislation.The federal, state and local governments in the areas in which we operate impose taxes on the oil and natural gas products we sell, and, for many ofour wells, sales and use taxes on significant portions of our drilling and operating costs. Many states have raised state taxes on energy sources or state taxesassociated with the extraction of hydrocarbons and additional increases may occur. In addition, there has been a significant amount of discussion bylegislators and presidential administrations concerning a variety of energy tax proposals.There have been proposals for legislative changes that, if enacted into law, would eliminate certain key U.S. federal income tax incentives currentlyavailable to oil and natural gas exploration and production companies. Such changes include, but are not limited to, (i) the repeal of the percentage depletionallowance for oil and gas properties; (ii) the elimination of current deductions for intangible drilling and development costs; (iii) the elimination of thededuction for certain U.S. production activities; and (iv) an extension of the amortization period for certain geological and geophysical expenditures. It isunclear whether these or similar changes will be enacted and, if enacted, how soon any such changes could become effective. Any such changes in U.S.federal income tax law could eliminate or defer certain tax deductions within the industry that are currently available with respect to oil and gas explorationand development, and any such change could negatively affect our financial condition, results of operations and cash flow.Changes to federal tax deductions, as well as any changes to or the imposition of new state or local taxes (including production, severance or similartaxes) could negatively affect our financial condition and results of operations.We are subject to cyber security risks. A cyber incident could occur and result in information theft, data corruption, operational disruption or financialloss.The oil and gas industry has become increasingly dependent on digital technologies to conduct certain exploration, development, production,processing and distribution activities. For example, we depend on digital technologies to interpret seismic data, manage drilling rigs, production equipmentand gathering and transportation systems, conduct reservoir modeling and reserves estimation and process and record financial and operating data. Pipelines,refineries, power stations and distribution points for both fuels and electricity are becoming more interconnected by computer systems. At the same time,cyber incidents, including deliberate attacks or unintentional events, have increased. Our technologies, systems, networks and those of our vendors, suppliersand other business partners may become the target of cyber-attacks or information security breaches that could result in the unauthorized release, gathering,monitoring, misuse, loss or destruction of proprietary and other information, or other disruption of our business operations. In addition, weaknesses in thecyber security of our vendors, suppliers, and other business partners could facilitate an attack on our technologies, systems and networks. In addition, certaincyber incidents, such as surveillance, may remain undetected for an extended period. Given the politically sensitive nature of hydraulic fracturing and thecontroversy generated by its opponents, our technologies, systems and networks may be of particular interest to certain groups with political agendas, whichmay seek to launch cyber-attacks as a method of promoting their message. Our systems and insurance coverage for protecting against cyber security risks maynot be sufficient.We depend on digital technology, including information systems and related infrastructure, as well as cloud applications and services, to processand record financial and operating data, communicate with our employees and business parties, analyze seismic and drilling information, estimate quantitiesof oil and gas reserves as well as other activities related to our business. Our business partners, including vendors, service providers, purchasers of ourproduction and financial institutions, are also dependent on digital technology. The technologies needed to conduct our oil and gas exploration anddevelopment activities make certain information the target of theft or misappropriation.Although to date we have not experienced any material losses relating to cyber-attacks, we may suffer such losses in the future.Risks Relating to our Common StockWe do not intend to pay, and we are currently prohibited from paying, dividends on our common stock and, consequently, our stockholders’ onlyopportunity to achieve a return on their investment is if the price of our stock appreciates.We do not plan to declare dividends on shares of our common stock in the foreseeable future. Additionally, we are currently prohibited from makingany cash dividends pursuant to the terms of our revolving credit facility and our Senior Notes. Consequently, our stockholders’ only opportunity to achieve areturn on their investment in us will be if the market price of our common stock appreciates, which may not occur, and the stockholders sell their shares at aprofit. There is no guarantee that the price of our common stock will ever exceed the price that the stockholders paid.52 Table of ContentsWe have experienced recent volatility in the market price and trading volume of our common stock and may continue to do so in the future.The trading price of shares of our common stock has fluctuated widely and in the future may be subject to similar fluctuations. As an example,during the year ended December 31, 2016, the sales price of our common stock ranged from a low of $0.60 per share to a high of $5.50 per share. The tradingprice of our common stock may be affected by a number of factors, including our bankruptcy proceeding, the volatility of oil, natural gas, and NGL prices,our operating results, changes in our earnings estimates, additions or departures of key personnel, our financial condition and liquidity, drilling activities,legislative and regulatory changes, general conditions in the oil and natural gas exploration and development industry, general economic conditions, andgeneral conditions in the securities markets. In particular, a significant or extended decline in oil, natural gas and NGL prices could have a material adverseeffect our sales price of our common stock. Other risks described in this annual report could also materially and adversely affect our share price.Although our common stock is listed on the New York Stock Exchange, we cannot assure you that an active public market will continue for ourcommon stock or that will be able to continue to meet the listing requirements of the NYSE. If an active public market for our common stock does notcontinue, the trading price and liquidity of our common stock will be materially and adversely affected. If there is a thin trading market or "float" for ourstock, the market price for our common stock may fluctuate significantly more than the stock market as a whole. Without a large float, our common stockwould be less liquid than the stock of companies with broader public ownership and, as a result, the trading prices of our common stock may be more volatile.In addition, in the absence of an active public trading market, investors may be unable to liquidate their investment in us.Our certificate of incorporation and bylaws, as well as Delaware law, contain provisions that could discourage acquisition bids or merger proposals, evenif such acquisition or merger may be in our stockholders’ best interests.Our certificate of incorporation authorizes our board of directors to issue preferred stock without stockholder approval. If our board of directorselects to issue preferred stock, it could be more difficult for a third party to acquire us. In addition, some provisions of our certificate of incorporation andbylaws could make it more difficult for a third party to acquire control of us, even if the change of control would be beneficial to our stockholders, including:•a classified board of directors, so that only approximately one-third of our directors are elected each year;•advance notice provisions for stockholder proposals and nominations for elections to the board of directors to be acted upon at meetings ofstockholders; and•limitations on the ability of our stockholders to call special meetings or act by written consent.Delaware law prohibits us from engaging in any business combination with any “interested stockholder,” meaning generally that a stockholder whobeneficially owns more than 15% of our stock cannot acquire us for a period of three years from the date this person became an interested stockholder, unlessvarious conditions are met, such as approval of the transaction by our board of directors.Item 1B. Unresolved Staff Comments.None.Item 2. Properties.The information required by Item 2. is contained in Item 1. Business and is incorporated herein by reference.Item 3. Legal Proceedings.From time to time, we are subject to legal proceedings and claims that arise in the ordinary course of business. Like other gas and oil producers andmarketers, our operations are subject to extensive and rapidly changing federal and state environmental, health and safety and other laws and regulationsgoverning air emissions, wastewater discharges, and solid and hazardous waste management activities. As of the date of this filing, there are no materialpending or overtly threatened legal actions against us that of which we are aware.During 2015, the Company voluntarily instigated an internal audit of its storage tank facilities located in the Wattenberg Field (the “Audit”). Thepurpose of the Audit was to determine compliance with applicable air quality regulations. Based on the results of the Audit, the Company self-reported inDecember 2015 and January 2016 several potential noncompliance issues to the Colorado Department of Public Health and Environment (“CDPHE”) underColorado’s Environmental Audit Privilege and Immunity Law (the “Environmental Audit Law”). Independently, in October 2015, CDPHE issued to theCompany a compliance advisory (the “Compliance Advisory”) for certain facilities that was closely related to the matters voluntarily disclosed as a result ofthe Audit.53 Table of ContentsThe Company has vigorously defended against the CDPHE allegations of violation while also cooperating with CDPHE in its investigation andfirmly asserting the Company’s right to civil penalty immunity for voluntarily disclosed violations under the Environmental Audit Law. In February 2017,following further interaction between the CDPHE and the Company, the CDPHE proposed settlement terms under which the Company would be required topay an administrative penalty in excess of $100,000 and perform certain mitigation projects and adopt certain procedures and processes addressing themonitoring, reporting, and reduction of emissions with respect to the Company’s storage tank facilities in the Wattenberg Field. The Company believes thatthe terms of settlement offered to the Company are part of a broader enforcement initiative the CDPHE is taking with multiple operators in the WattenbergField.Although the Company intends to continue working with the CDPHE in an attempt to reach a consensual resolution of the relevant compliancematters, the Company firmly believes that the proposed terms of settlement are neither mandated by the applicable air quality regulations nor consistent withthe Company’s historical practices or its rights under the Environmental Audit Law. It is not possible to determine at this time whether the Company willultimately be subject to any civil penalty assessment in connection with the resolution of compliance issues identified in the Audit and the ComplianceAdvisory.For discussion of our ongoing bankruptcy proceedings, see Part I, Item 1.

Covenants contained in our revolving credit facility and the indenturesgoverning our Senior Notes restrict the payment of cash dividends on our common stock. We currently intend to retain all future earnings for thedevelopment and growth of our business, and we do not anticipate declaring or paying any cash dividends to holders of our common stock in the foreseeablefuture.54 Table of ContentsIssuer Purchases of Equity Securities.

Management’s Discussion and Analysis of Financial Condition and Results of Operations. Executive Summary We are a Denver-based exploration and production company focused on the extraction of oil and associated liquids-rich natural gas in the UnitedStates. Our oil and liquids-weighted assets are concentrated primarily in the Wattenberg Field in Colorado and the Dorcheat Macedonia Field in southernArkansas.Effective as of January 1, 2015, the Company revised the agreements with its natural gas processors in the Rocky Mountain region to report operatedsales volumes on a three-stream basis, which allows for separate reporting of NGLs extracted from the natural gas stream and sold as a separate product. Thecontract revisions necessitated a change in our reporting of sales volumes. Years prior to 2015 sales volumes, revenues, and prices have not been reclassifiedto conform to the current presentation given the prospective nature of the agreements. The NGL volumes identified by the Company’s gas purchasers areconverted to an oil equivalent. The Company believes that this conversion will more accurately convey its production and sales volumes and will allowresults to be more comparable with those of our peers. This revision will increase reserves volumes, sales volumes and the percentage of sales volumes thatrelate to NGLs. Bankruptcy Proceedings under Chapter 11Restructuring Support AgreementOn December 23, 2016, the Company entered into a Restructuring Support Agreement (the “RSA”) with (i) holders of approximately 51% inaggregate principal amount of the Company’s 5.75% Senior Notes due 2023 and 6.75% Senior Notes due 2021 and (ii) NGL Energy Partners, LP and NGLCrude Logistics, LLC.The RSA contemplates, among other things, (a) the equitization of the Company’s unsecured obligations pursuant to the Plan, includingapproximately $800 million in principal amount of Senior Notes, (b) a fully backstopped rights offering for the purchase of $200 million of common stock ofreorganized Bonanza Creek Energy, Inc., and (c) the entry into a new crude oil purchase agreement between the Company and NGL Crude Logistics, LLC.Voluntary Chapter 11 Bankruptcy ProceedingsOn January 4, 2017 (the “Petition Date”), the Company and all of its direct and indirect subsidiaries (collectively, the “Debtors”) filed voluntarypetitions (the “Bankruptcy Petitions,” and the cases commenced thereby, collectively, the “Chapter 11 Cases”) under chapter 11 of title 11 of the UnitedStates Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”) to pursue the Debtors’Joint Prepackaged Plan of Reorganization Under Chapter 11 of the Bankruptcy Code (as amended, restated, supplemented or otherwise modified from time totime, the “Prepackaged Plan”). The Debtors are authorized to operate their businesses as debtors in possession under the jurisdiction of the Bankruptcy Courtand in accordance with the applicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court.The Bankruptcy Court has granted on a final basis all of the first day motions filed by the Debtors seeking relief that would minimize the impact ofthe Chapter 11 Cases on the Company's operations, customers and employees. As a result, the Company is not only authorized to conduct business activitiesin the ordinary course and generally pay all associated obligations for the period following the Petition Date without further Bankruptcy Court approval, butit is also currently authorized to pay and has paid, subject to certain limitations, obligations that arose prior to the Petition Date related to employee wagesand benefits, services and supplies provided by vendors in the ordinary course of business and mineral interests held by royalty holders and other partners. Ingeneral, during the pendency of the Chapter 11 Cases, all transactions outside the ordinary course of our business require the prior approval of theBankruptcy Court. As a result of the automatic stay under the Bankruptcy Code, which became effective upon the commencement of the Chapter 11 Cases,most judicial or administrative actions against the Company by its creditors to collect on or otherwise exercise rights or remedies with respect to claims thatarose before the Petition Date are stayed during the pendency of the Chapter 11 Cases.A hearing to consider confirmation of the Prepackaged Plan and approval of the Debtors’ Disclosure Statement is currently scheduled to begin onApril 3, 2017.For a further description of these matters, see Note 19 - Subsequent Events.Financial and Operating Results 59 Table of ContentsOur 2016 financial and operational results include:•Total liquidity of $38.9 million at December 31, 2016, consisting of, year-end cash balance net of the borrowing base deficiency under therevolving credit facility, as compared with $405.3 million, consisting of, year-end cash balance plus funds available under our revolving creditfacility at December 31, 2015. Please refer to Liquidity and Capital Resources below for additional discussion;•Lease operating expense in aggregate and on a per Boe basis was down 33% and 13%, respectively, from 2015 due to decreased operating costs andreduced activity levels;•Cash flows provided by operating activities of $14.6 million, as compared with $226.0 million in 2015. Please refer to Liquidity and CapitalResources below for additional discussion;•Full year capital expenditures were $21.7 million;•Net loss of $199.0 million, as compared with a net loss of $745.5 million for 2015;•Decreased sales volumes by 23% to 7.9 MMBoe in 2016 from 10.3 MMBoe in 2015, with oil and NGL production representing 74% of total salesvolumes;•Decreased proved reserves by 10% to 90.7 MMBoe as of December 31, 2016, from 101.3 MMBoe as of December 31, 2015. Business Strategies and Outlook for 2017Our strategy is to operate a development program on contiguous acreage blocks that have high working interest, allowing us to control the pace andmagnitude of our future capital expenditures and provide efficient resource development through multi-well pads and centralized facilities. Upon emergencefrom bankruptcy, management currently intends to operate a one-rig program in 2017 to drill 61 operated standard reach lateral equivalent wells that arewithin close proximity to the Company's existing infrastructure to keep costs down. Actual capital expenditures could vary significantly based on, amongother things, emergence from bankruptcy, approval from a newly appointed board, market conditions, commodity prices, the final amount of the rightsoffering effectuated pursuant to the RSA, and changes in the borrowing base under our revolving credit facility. We have also observed evidence of anincrease in drilling and completion costs since year end, which will have an impact on our 2017 capital expenditures.Results of Operations The following discussion and analysis should be read in conjunction with our consolidated financial statements and the notes thereto contained inPart II, Item 8 of this Annual Report on Form 10-K. Comparative results of operations for the period indicated are discussed below.60 Table of ContentsThe table below presents revenues, sales volumes, and average sales prices for the years ended December 31, 2016 and 2015: For the Years Ended December 31, 2016 2015 Change Percent Change (In thousands, except percentages)Operating Revenues: Crude oil sales(1)$152,673 $248,862 $(96,189) (39)%Natural gas sales(2) 22,962 26,528 (3,566) (13)%Natural gas liquids sales 19,660 17,289 2,371 14 %Product revenue$195,295 $292,679 $(97,384) (33)% Sales Volumes: Crude oil (MBbls) 4,309.9 6,072.3 (1,762.4) (29)%Natural gas (MMcf) 12,231.3 14,551.1 (2,319.8) (16)%Natural gas liquids (MBbls) 1,587.0 1,821.9 (234.9) (13)%Crude oil equivalent (MBoe)(3) 7,935.5 10,319.4 (2,383.9) (23)% Average Sales Prices (before derivatives): Crude oil (per Bbl)$35.42 $40.98 $(5.56) (14)%Natural gas (per Mcf)$1.88 $1.82 $0.06 3 %Natural gas liquids (per Bbl)$12.39 $9.49 $2.90 31 %Crude oil equivalent (per Boe)(3)$24.61 $28.36 $(3.75) (13)% Average Sales Prices (after derivatives)(4): Crude oil (per Bbl)$39.68 $62.10 $(22.42) (36)%Natural gas (per Mcf)$1.88 $2.01 $(0.13) (6)%Natural gas liquids (per Bbl)$12.39 $9.49 $2.90 31 %Crude oil equivalent (per Boe)(3)$26.92 $41.06 $(14.14) (34)%_____________________________(1)Crude oil sales includes $0.5 million and $0.2 million of oil transportation revenues from third parties, which do not have associated sales volumes, forthe years ended December 31, 2016 and 2015, respectively.(2)Natural gas sales includes $1.5 million and $0.8 million of gas gathering revenues from third parties, which do not have associated sales volumes, for theyears ended December 31, 2016 and 2015, respectively.(3)Determined using the ratio of 6 Mcf of natural gas to 1 Bbl of crude oil.(4)The derivatives economically hedge the price we receive for crude oil and natural gas. For the years ended December 31, 2016 and 2015, the derivativecash settlement gain for oil contracts was $18.3 million and $128.3 million, respectively, and the derivative cash settlement gain for gas contracts was$2.7 million for the year ended December 31, 2015. Please refer to Part II, Item 8, Note 13 - Derivatives for additional disclosures. Revenues decreased by 33% to $195.3 million for the year ended December 31, 2016 compared to $292.7 million for the year ended December 31,2015 largely due to a 23% decrease in sales volumes coupled with a 13% decrease in oil equivalent pricing. The decreased volumes are a direct result of theCompany suspending all drilling and completion activities after the first quarter of 2016. During the period from December 31, 2015 through December 31,2016, we drilled 17 gross (8.4 net) and completed 21 gross (13.0 net) wells in the Rocky Mountain region and drilled no wells in the Mid-Continent region. 61 Table of ContentsThe following table summarizes our operating expenses for the periods indicated.

Our lease operating expense decreased $21.4 million or 33%, to $43.7 million for the year ended December 31, 2016 from$65.0 million for the year ended December 31, 2015 and decreased on an equivalent basis from $6.30 per Boe to $5.50 per Boe. The majority of the decreaseis due to continued operating cost reductions along with decreased activity levels. The Company reduced operating costs and negotiated contract reductionsresulting in decreased well servicing costs of $10.1 million, compression costs of $4.9 million and pumping and gauging costs of $2.7 million during theyear ended December 31, 2016 when compared to the same period in 2015.Gas plant and midstream operating expense. Our gas plant and midstream operating expense increased $1.5 million to $12.8 million for the yearended December 31, 2016 from $11.4 million for the year ended December 31, 2015 and increased on an equivalent basis from $1.10 per Boe to $1.62 perBoe. The increase in aggregate and on an equivalent basis is due to the start-up and continued buildout of RMI, which began in May of 2015. Severance and ad valorem taxes. Our severance and ad valorem taxes decreased by 18%, or $3.3 million to $15.3 million for the year endedDecember 31, 2016 from $18.6 million for the year ended December 31, 2015. Severance and ad62 Table of Contentsvalorem taxes primarily correlate to revenue. Revenues decreased by 33% for the year ended December 31, 2016 when compared to the same period in 2015,which was offset by a tax refund received during the third quarter of 2015. Exploration. Our exploration expense decreased $14.9 million to $0.9 million during the year ended December 31, 2016 from $15.8 million for theyear ended December 31, 2015. During the year ended December 31, 2016, we incurred minimal exploration charges. During the year ended December 31,2015 we incurred charges of $5.6 million and $8.5 million for exploratory wells located in the North Park Basin and outside of our current development areain southern Arkansas, respectively, which we were unable to assign economic proved reserves. During 2015, we also paid $1.0 million and $0.7 million ingeological and geophysical expenses and delay rentals, respectively. Depreciation, depletion and amortization. Our depreciation, depletion and amortization expense decreased $133.7 million, or 55%, to $111.2million for the year ended December 31, 2016 from $244.9 million for the year ended December 31, 2015 and decreased on an equivalent basis from $23.73per Boe to $14.01 per Boe. The Company realized significant proved property impairments during the fourth quarter of 2015 resulting in a 50% decrease inthe net proved property depletable base from the year ended December 31, 2015 to December 31, 2016.Impairment of oil and gas properties. For the year ended December 31, 2016 we incurred an impairment of proved properties of $10.0 million, a$730.5 million decrease from the year ended December 31, 2015. We impaired our Mid-Continent assets by $10.0 million based on the most recent bidreceived during the first quarter of 2016, when it was held for sale. For the year ended December 31, 2015, we impaired our Mid-Continent assets by $321.2million due to their depressed fair value upon classification as held for sale and our Rocky Mountain assets by $419.3 million due to low commodity prices.Please refer to Note 1 - Summary of Significant Accounting Policies in Part II, Item 8 of this Annual Report on Form 10-K for additional discussion on ourimpairment policy and practice.Abandonment and impairment of unproved properties. For the year ended December 31, 2016 we incurred an abandonment and impairment ofunproved properties of $24.7 million, an $8.9 million decrease from the prior year. Our 2016 abandonment and impairment charges related to non-core leasesexpiring within the Wattenberg Field. During the year ended December 31, 2015, we incurred $24.8 million of impairment charges relating to non-core leasesexpiring within the Wattenberg Field and $8.7 million of impairment charges to fully impair the North Park Basin due to a strategic shift in our developmentplan.Unused commitments. For the year ended December 31, 2016, we incurred $7.7 million in unused commitment fees. During 2015, we did not incurany fees of this nature. The unused commitment fees in 2016 of $4.3 million and $3.4 million are the result of water commitment deficiency payments andpurchase and transportation agreement deficiency payments, respectively. Please see Note 8 - Commitments and Contingencies in Part II, Item 8 of thisAnnual Report on Form 10-K for additional discussion.Contract settlement expense. For the year ended December 31, 2016 we incurred a $21.0 million loss to settle our crude oil purchase agreement withSilo as part of our bankruptcy process. There were no material settlements during 2015. Please see Note 8 - Commitments and Contingencies in Part II, Item 8of this Annual Report on Form 10-K for additional discussion. General and administrative expense. Our general and administrative expense increased $6.7 million, or 10%, to $77.1 million for the year endedDecember 31, 2016 from $70.3 million for the comparable period in 2015 and increased on an equivalent basis to $9.71 per Boe from $6.81 per Boe. Theincrease in general and administrative expense in 2016 on an aggregate and equivalent basis is due to $20.4 million of advisory fees related to ourrestructuring efforts and an increase of $1.2 million in severance payments. These cost increases were offset by a decrease in salaries and wages, includingbenefits of $9.3 million and stock compensation of $5.7 million due to reductions in workforce that have occurred since December 31, 2015. Derivative gain (loss). Our derivative loss increased $67.8 million to an $11.2 million loss for the year ended December 31, 2016 from a gain of$56.6 million for the comparable period in 2015. The decrease is related to a reduction of hedged volumes throughout 2016 and decreased contract prices atthe time of conversion from three-way collars to swap and puts at the end of the first quarter of 2016 bringing them closer to realized prices during the yearended December 31, 2016 when compared to the same period in 2015. Please refer to Note 13 - Derivatives in Part II, Item 8 of this Annual Report on Form10-K for additional discussion. 63 Table of ContentsInterest expense. Our interest expense for the year ended December 31, 2016 increased 9% to $62.1 million compared to $57.1 million for the yearended December 31, 2015. The interest expense increase is a result of increased average debt outstanding for the year ended December 31, 2016 of$1.0 billion, compared to $847.9 million for the comparable period in 2015. Total interest expense is comprised primarily of interest expense attributable tothe Senior Notes including amortization of the premium and financing costs, which was $52.3 million and $52.1 million for the years ended December 31,2016 and 2015, respectively. Income tax benefit (expense). Our estimate for federal and state income tax benefit for the years ended December 31, 2016 and 2015 was zero and$164.9 million, respectively. We are allowed to deduct various items for tax reporting purposes that are capitalized for purposes of financial statementpresentation. Our effective tax rate for the years ended December 31, 2016 and 2015 was 0.0% and 18.1%, respectively. As of December 31, 2015, a fullvaluation was placed against the net deferred tax assets, which caused effective tax rate to differ from the U.S. statutory income tax rate.Year Ended December 31, 2015 Compared to Year Ended December 31, 2014The table below presents revenues, sales volumes, and average sales prices for the years ended December 31, 2015 and 2014: For the Years Ended December 31, 2015(1) 2014(4) Change Percent Change (In thousands, except percentages)Operating Revenues: Crude oil sales(5)$248,862 $460,442 $(211,580) (46)%Natural gas sales(6) 26,528 78,714 (52,186) (66)%Natural gas liquids sales 17,289 19,470 (2,181) (11)%CO2 sales — 7 (7) (100)%Product revenue$292,679 $558,633 $(265,954) (48)% Sales Volumes: Crude oil (MBbls) 6,072.3 5,618.7 453.6 8 %Natural gas (MMcf) 14,551.1 15,395.8 (844.7) (5)%Natural gas liquids (MBbls) 1,821.9 396.2 1,425.7 360 %Crude oil equivalent (MBoe)(2) 10,319.4 8,580.9 1,738.5 20 % Average Sales Prices (before derivatives): Crude oil (per Bbl)$40.98 $81.95 $(40.97) (50)%Natural gas (per Mcf)$1.82 $5.11 $(3.29) (64)%Natural gas liquids (per Bbl)$9.49 $49.14 $(39.65) (81)%Crude oil equivalent (per Boe)(2)$28.36 $65.10 $(36.74) (56)% Average Sales Prices (after derivatives)(3): Crude oil (per Bbl)$62.10 $84.00 $(21.90) (26)%Natural gas (per Mcf)$2.01 $5.16 $(3.15) (61)%Natural gas liquids (per Bbl)$9.49 $49.14 $(39.65) (81)%Crude oil equivalent (per Boe)(2)$41.06 $66.53 $(25.47) (38)%________________________________(1)Effective as of January 1, 2015, the Company revised the agreements with its natural gas processors in the Rocky Mountain region to report operatedsales volumes on a three-stream basis, which allows for separate reporting of NGLs extracted from the natural gas stream and sold as a separate product.The contract revisions necessitated a change in our reporting of sales volumes.

There was no oil transportation revenues for the year ended December 31, 2014.(6)Natural gas sales includes $0.8 million of gas gathering revenues from third parties, which do not have associated sales volumes, for the year endedDecember 31, 2015. There was no gas gathering revenues for the year ended December 31, 2014. Revenues decreased by 48% to $292.7 million for the year ended December 31, 2015 compared to $558.6 million for the year ended December 31,2014 largely due to a 56% decrease in oil equivalent pricing. The decreased pricing was offset by increased sales volumes of 20% for the year endedDecember 31, 2015 compared to the same period in 2014. The increased volumes are a direct result of $404.0 million expended for drilling and completionduring 2015. During the period from December 31, 2014 through December 31, 2015, we drilled 84 gross (66 net) and completed 95 gross (77.1 net) wells inthe Rocky Mountain region and drilled 24 gross (22.2 net) and completed 21 gross (19.4 net) wells in the Mid-Continent region.

Lease operating expense. Our lease operating expense increased $5.2 million or 9%, to $65.0 million for the year ended December 31, 2015 from$59.9 million for the year ended December 31, 2014 and decreased on an equivalent basis from $6.98 per Boe to $6.30 per Boe. The increase in aggregatelease operating expense was related to the 20% increase in sales volumes during the year ended December 31, 2015 when compared to the same period in2014. During the year ended December 31, 2015, the largest component of lease operating expense was compression, which increased $4.0 million over thecomparable period in 2014. The Company reduced operating costs and negotiated contract reductions while increasing production for the year endedDecember 31, 2015, driving the per equivalent barrel rate down when compared to the same period in 2014.Gas plant and midstream operating expense. Our gas plant and midstream operating expense decreased by 9%, to $11.4 million for the year endedDecember 31, 2015 from $12.5 million for the year ended December 31, 2014. The decrease is primarily due to the Company idling the McKamie gas plantduring the second quarter of 2015, which was partially offset by RMI beginning operations in May of 2015. Severance and ad valorem taxes. Our severance and ad valorem taxes decreased $31.8 million to $18.6 million for the year ended December 31,2015 from $50.4 million for the year ended December 31, 2014. Severance and ad valorem taxes primarily correlate to revenue. Revenues decreased by 48%for the year ended December 31, 2015 when compared to the same period in 2014 causing the severance and ad valorem taxes to decrease. Severance and advalorem taxes were further reduced by a tax refund received during 2015. Additionally, our ad valorem tax credits available for deduction increased in 2015when compared to the same period in 2014 due to continued development of the Wattenberg Field which further reduced our effective severance tax rate. Exploration. Our exploration expense increased $10.5 million to $15.8 million during the year ended December 31, 2015 from $5.3 million for theyear ended December 31, 2014. During the year ended December 31, 2015, we incurred charges for exploratory wells located in both the North Park Basinand outside of our current development area in southern Arkansas for $5.6 million and $8.5 million, respectively, which we were unable to assign economicproved reserves, and paid $1.0 million and $0.7 million in geological and geophysical expenses and delay rentals, respectively. In 2014, we incurred $3.4million of seismic charges for an acquisition project within the Wattenberg Field, a $1.0 million dry hole charge related to a vertical well within theWattenberg Field drilled to test the Lyons formation, and $0.9 million in delay rentals. Depreciation, depletion and amortization. Our depreciation, depletion and amortization expense increased $16.1 million, or 7%, to $244.9 millionfor the year ended December 31, 2015 from $228.8 million for the year ended December 31, 2014 and decreased on an equivalent basis from $26.66 per Boeto $23.73 per Boe. The decrease in equivalent basis was primarily due to depreciation ceasing once assets were deemed held for sale coupled with a 20%increase in sales volumes.Impairment of oil and gas properties. Our impairment of proved properties increased $572.9 million to $740.5 million for the year endedDecember 31, 2015 when compared to year ended December 31, 2014. We impaired our Mid-Continent assets by $321.2 million due to their depressed fairvalue from low commodity prices upon classification as held for sale and our Rocky Mountain assets by $419.3 million due to low commodity prices. For theyear ended December 31, 2014, we impaired $127.3 million of proved properties within the Dorcheat Macedonia Field due to low commodity prices, $25.0million of non-core proved properties within the McKamie Patton Field due to low commodity prices, and $15.3 million of proved properties in ourMcCallum Field due to low commodity prices and a strategic shift to horizontal drilling. Please refer to Note 1 - Summary of Significant Accounting Policiesin Part II, Item 8 of this Annual Report on Form 10-K for additional discussion on our impairment policy and practice.Abandonment and impairment of unproved properties. Our abandonment and impairment of unproved properties increased to $33.5 million for theyear ended December 31, 2015 when compared to the year ended December 31, 2014. We incurred $24.8 million of impairment charges relating to non-coreleases expiring within the Wattenberg Field and $8.7 million of impairment charges to fully impair the North Park Basin due to a strategic shift in ourdevelopment plan. There were no unproved properties abandoned or impaired during the year ended December 31, 2014. General and administrative expense. Our general and administrative expense decreased $11.3 million, or 14%, to $70.3 million for the year endedDecember 31, 2015 from $81.6 million for the comparable period in 2014 and decreased on an equivalent basis to $6.81 per Boe from $9.51 per Boe. Thedecrease in general and administrative expense for the year ended66 Table of ContentsDecember 31, 2015 when compared to the same period in 2014 was primarily due to executive departure costs that occurred in 2014. The decrease inequivalent basis was caused by the 20% increase in sales volumes outpacing the change in the expense. Derivative gain. Our derivative gain decreased $65.0 million to $56.6 million for the year ended December 31, 2015 from a gain of $121.6 millionfor the comparable period in 2014. The decrease in gain is related to a reduction in hedged volumes during the year ended December 31, 2015 whencompared to the year ended December 31, 2014. Please refer to Note 13 - Derivatives in Part II, Item 8 of this Annual Report on Form 10-K for additionaldiscussion. Interest expense. Our interest expense for the year ended December 31, 2015 increased 23% to $57.1 million compared to $46.4 million for the yearended December 31, 2014 due to the average debt outstanding for the year ended December 31, 2015 being $847.9 million as compared to $644.4 million forthe comparable period in 2014. Interest expense, including amortization of the premium and financing costs, on the Senior Notes for the years endedDecember 31, 2015 and 2014 was $52.1 million and $42.3 million, respectively. Income tax benefit (expense). Our estimate for federal and state income tax benefit for the year ended December 31, 2015 was $164.9 million ascompared to income tax expense of $11.0 million for the year ended December 31, 2014. We are allowed to deduct various items for tax reporting purposesthat are capitalized for purposes of financial statement presentation. Our effective tax rate for the year ended December 31, 2015 was 18.1% as compared to39.3% for the year ended December 31, 2014. These rates differ from the U.S. statutory income tax rate primarily due to the effects of state income taxes and avaluation allowance being placed against net deferred tax assets.Results for Discontinued OperationsDuring June of 2012, the Company began marketing, with an intent to sell, all of its oil and gas properties in California. The Company determined,at that time, that our intent to sell out of an entire region qualified for discontinued operations accounting and these assets have been presented asdiscontinued operations in the accompanying statements of operations.The majority of these properties were sold in 2012. The remaining property located in the Midway Sunset Field sold on March 21, 2014 forapproximately $6.0 million and resulted in a $5.5 million gain.The operating results before income taxes for our California properties for the year ended December 31, 2014 were net revenues of $0.4 million, andoperating expenses of $0.4 million, as compared to net revenues of $1.7 million, and operating expenses of $2.3 million for the year ended December 31,2013. Sales volumes for the years ended December 31, 2014 and 2013 were 10 Boe/d and 47 Boe/d, respectively.Liquidity and Capital ResourcesOur primary sources of liquidity have historically included cash from operating activities, borrowings under the revolving credit facility, proceedsfrom sales of assets and, from time to time, proceeds from capital market transactions, including the offering of debt and equity securities. Our cash flows fromoperating activities are subject to significant volatility due to changes in commodity prices for our crude oil, NGL and natural gas products, as well asvariations in our production. The prices for these commodities are driven by a number of factors beyond our control, including global and regional productsupply and demand, weather, product distribution, refining and processing capacity and other supply chain dynamics, among other factors.Since the first quarter of 2016, the Company’s liquidity outlook has deteriorated due to the Company's inability to sell assets given current marketconditions and counterparty concerns about the Company's liquidity and current capital structure, borrowing base reductions that have occurred during2016, continuation of depressed commodity prices and the inability to access the debt and capital markets. The Company is currently in default on itsrevolving credit facility and Senior Notes. The lenders and noteholders had the option to accelerate the repayment of their respective debts at the time ofdefault. The Company did not receive a notice of acceleration prior to filing for bankruptcy.Currently, our liquidity is $38.9 million, which is comprised of our available cash on hand of $80.6 million reduced by our borrowing basedeficiency of $41.7 million as of December 31, 2016.Upon our emergence from bankruptcy, which we anticipate in the first half of 2017, we expect to have a new four-year senior secured revolvingcredit facility in place which is intended to provide us with an initial borrowing base equal to our67 Table of Contentsoutstanding balance under our existing revolving credit agreement of $191.7 million. As contemplated in the RSA we will have access to the net proceeds ofa $200 million rights offering. After emergence from bankruptcy, management currently intends on investing $160.0 million to $180.0 million in a one-rigprogram in 2017 to drill 61 operated standard reach lateral equivalent wells that are within close proximity to the Company's existing infrastructure. Actualcapital expenditures could vary significantly.While we are in default on our indebtedness and have filed for bankruptcy, we will no longer be able to represent that we can comply with the creditdefault or bankruptcy covenants of different agreements to which we are a party. There can be no assurances regarding our ability to successfully develop,confirm and consummate one or more plans of reorganization or other alternative restructuring transactions that satisfies the conditions of the BankruptcyCode and, is approved by the Bankruptcy Court.The following table summarizes our cash flows and other financial measures for the periods indicated.

The decrease in cash flows from operating activities of $113.9 million from December 31, 2014 to December 31, 2015 resulted primarily from a 56%decrease in crude oil equivalent pricing and a $31.8 million reduction in severance and ad valorem taxes paid that were partially offset by a 20% increase insales volumes and $118.8 million increase in derivative cash settlements. See Results of Operations above for more information on the factors driving thesechanges.Cash flows used in investing activities Expenditures for development of oil and natural gas properties are the primary use of our capital resources. Net cash used in investing activities forthe year ended December 31, 2016 decreased $385.2 million as compared to the same period in 2015. For the year ended December 31, 2016, cash used forthe acquisition of oil and gas properties was $98,000 and cash used for the development of oil and natural gas properties was $52.3 million. Net cash used ininvesting activities for the year ended December 31, 2015 decreased $384.7 million as compared to the same period in 2014. For the year endedDecember 31, 2015, cash used for the acquisition of oil and gas properties was $16.3 million and cash used for the development of oil and natural gasproperties was $425.9 million. For the year ended December 31, 2014, cash used for the acquisition of oil and gas properties was $179.6 million and cashused for the development of oil and natural gas properties was $641.2 million. Cash flows provided by financing activities Net cash provided by financing activities for the year ended December 31, 2016 decreased $133.2 million, compared to the same period in 2015.The decrease was primarily due to $202.7 million of net proceeds from the sale of common stock that occurred during 2015 that did not occur in 2016 andwas offset by an increase in net borrowings under the revolving credit facility of $66.7 million in 2016 when compared to 2015. Net cash provided byfinancing activities for the year ended December 31, 2015 decreased $74.0 million, compared to the same period in 2014. The decrease was primarily due to$202.7 million of net proceeds from the sale of common stock that occurred during the year plus net borrowings of $46.0 million from68 Table of Contentsour revolving credit facility compared to $292.9 million of net proceeds from the sale of Senior Notes plus net borrowings of $33.0 million from ourrevolving credit facility during the year ended December 31, 2014.Credit facilityRevolving Credit FacilityThe administrative agent of our $1.0 billion revolving credit facility is KeyBank National Association. The revolving credit facility provides forinterest rates plus an applicable margin to be determined based on the London Interbank Offered Rate (“LIBOR”) or a bank base rate (“Base Rate”), at theCompany’s election. LIBOR borrowings bear interest at LIBOR plus 1.50% to 2.50% depending on the utilization level, and the Base Rate borrowings bearinterest at the “Bank Prime Rate,” as defined in the revolving credit facility, plus 0.50% to 1.50%. The applicable lenders under the revolving credit facilitydeemed the Company in default due to a covenant violation on November 14, 2016 causing the then outstanding balance under the revolving credit facilityto bear interest at the Bank Prime Rate plus the applicable utilization margin and 2% penalty fee.Our approved borrowing base under the revolving credit facility, which was $150.0 million as of December 31, 2016, is redetermined semiannuallyas early as April and October of each year and up to one additional time between such scheduled determinations upon our request or upon the request of therequired lenders (defined as lenders holding 662/3% of the aggregate commitments). The borrowing base is determined by the value of our oil and gasreserves but also takes into consideration such information as a repayment analysis of the Company's debt and the forecasted financial condition of theCompany. The borrowing base is redetermined (i) in the sole discretion of the administrative agent and all of the lenders, (ii) in accordance with theircustomary internal standards and practices for valuing and redetermining the value of oil and gas properties in connection with reserve based oil and naturalgas loan transactions, (iii) in conjunction with the most recent engineering report and other information received by the administrative agent and the lendersrelating to our proved reserves and (iv) based upon the estimated value of our proved reserves as determined by the administrative agent and the lenders.As of December 31, 2016, the Company had $191.7 million outstanding under the revolving credit facility and had a borrowing base deficiency of$41.7 million to be paid back in five remaining monthly installments of $8.3 million, with no additional available borrowing capacity. The Company filedfor Chapter 11 under the Bankruptcy Code on January 4, 2017, allowing the Company a stay from making any further deficiency payments. For additionaldiscussion, please refer to Note 19 - Subsequent Events. The revolving credit facility may be used only to finance development of oil and gas properties, forworking capital and for other general corporate purposes.Our obligations under the revolving credit facility are secured by first priority liens on all of our property and assets (whether real, personal, ormixed, tangible or intangible), including our proved reserves and our oil and gas properties (which term is defined to include fee mineral interests, termmineral interests, leases, subleases, farm-outs, royalties, overriding royalties, net profit interests, carried interests, production payments, back in interests andreversionary interests). The revolving credit facility is guaranteed by the Company and all of its direct and indirect subsidiaries.The applicable margin varies on a daily basis based on the percentage outstanding under the borrowing base. We incur quarterly commitment feesbased on the unused amount of the borrowing base ranging from 0.375% and 0.50% per annum. We may prepay loans under the revolving credit facility atany time without premium or penalty (other than customary LIBOR breakage costs).The revolving credit facility contains various covenants limiting our ability to:•grant or assume liens;•incur or assume indebtedness;•grant negative pledges or agree to restrict dividends or distributions from subsidiaries;•sell, transfer, assign or convey assets, or engage in certain mergers or acquisitions;•make certain distributions;•make certain loans, advances and investments;•engage in transactions with affiliates;69 Table of Contents•enter into sale and leaseback, take-or-pay or hydrocarbon prepayment transactions; or•enter into certain swap agreements.The revolving credit facility also contains covenants requiring us to maintain:•a current ratio (i.e., the ratio of current assets to current liabilities, excluding unsettled derivatives and the current portion of long-term debt) ofnot less than 1.0 to 1.0 (current assets include, as of the date of calculation, the aggregate of all lenders’ unused commitment amounts);•a maximum senior secured debt (defined as borrowings under the revolving credit facility, balances drawn under letters of credit, and anyoutstanding second lien debt) to trailing twelve-month earnings before interest, income taxes, depreciation, depletion, and amortization,exploration expense and other non-cash charges (“EBITDAX”) covenant that must not exceed 2.50 to 1.00; and•a minimum interest coverage ratio calculated by dividing trailing twelve-month EBITDAX by trailing twelve-month interest expense that mustexceed 2.50 to 1.00.The revolving credit facility contains customary events of default, including:•failure to pay any principal, interest, fees, expenses or other amounts when due;•the failure of any representation or warranty to be materially true and correct when made;•failure to observe any agreement, obligation or covenant in the credit agreement, subject to cure periods for certain failures;•a cross-default for the payment of any other indebtedness of at least $2 million;•bankruptcy or insolvency;•judgments against us or our subsidiaries, in excess of $2 million, that are not stayed;•certain ERISA events involving us or our subsidiaries; and•a change in control (as defined in the revolving credit facility), including the ownership by a “person” or “group” (as defined under theSecurities and Exchange Act of 1934, as amended, but excluding certain permitted stockholders) directly or indirectly, of more than 35% of ourcommon stock, other than certain of our current stockholders.As of December 31, 2016, and through the filing date of this report, we were no longer in compliance with our minimum interest coverage ratiorequirement allowing the applicable lenders to give notice of acceleration as a result of this non-compliance. As of December 31, 2016, the Company had notreceived a notice of acceleration. Upon filing for bankruptcy, the Company was granted a stay from creditors exercising any remedy efforts. The Companyand its lenders have negotiated the terms of a revised revolving credit facility that would become effective upon our emergence from bankruptcy.Contractual Obligations 70 Table of ContentsWe have the following contractual obligations and commitments as of December 31, 2016: Less than More than Total 1 Year 1 - 3 Years 3 - 5 Years 5 Years (in thousands)Contractual Obligation Senior Notes $800,000 $— $— $500,000 $300,000Interest on Senior Notes(1) 249,829 51,000 102,000 78,094 18,735Revolving credit facility(2) 191,667 191,667 — — —Delivery commitments(3) 437,069 89,611 179,222 99,250 68,986Operating leases(3) 10,725 2,767 5,659 2,299 —Asset retirement obligations(4) 136,971 2,673 3,724 7,909 122,665Total $1,826,261 $337,718 $290,605 $687,552 $510,386___________________(1)Amounts represent the interest to be paid on the Company's Senior Notes up through their contractual maturities of 2021 and 2023.(2)The revolving credit facility matures in September 2017.(3)The Company has two purchase and transportation agreements, one of which has been terminated and the other's terms have been amended subsequent toyear end and subject to confirmation. Please refer to Note 8 - Commitments and Contingencies to our consolidated financial statements for additionaldiscussion on these agreements and for a description of our operating leases.(4)Amounts represent our estimated future retirement obligations on an undiscounted basis. The discounted obligations are recorded as liabilities on ouraccompanying balance sheets as of December 31, 2016. Because these costs typically extend many years into the future, management prepares estimatesand makes judgments that are subject to future revisions based upon numerous factors. Please see Note 11 - Asset Retirement Obligation, for additionaldiscussion.Critical Accounting Policies and Estimates The discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which havebeen prepared in accordance with accounting principles generally accepted in the United States. The preparation of our financial statements requires us tomake estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets andliabilities. Certain accounting policies involve judgments and uncertainties to such an extent that there is reasonable likelihood that materially differentamounts could have been reported under different conditions, or if different assumptions had been used. We evaluate our estimates and assumptions on aregular basis. We base our estimates on historical experience and various other assumptions that are believed to be reasonable under the circumstances, theresults of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actualresults may differ from these estimates and assumptions used in preparation of our consolidated financial statements. We provide expanded discussion of ourmore significant accounting policies, estimates and judgments below. We believe these accounting policies reflect our more significant estimates andassumptions used in preparation of our consolidated financial statements. See Note 1 - Summary of Significant Accounting Policies to our auditedconsolidated financial statements for a discussion of additional accounting policies and estimates made by management.Method of accounting for oil and natural gas propertiesOil and natural gas exploration and development activities are accounted for using the successful efforts method. Under this method, all propertyacquisition costs and costs of exploratory and development wells are capitalized at cost when incurred, pending determination of whether the well has foundproved reserves. If an exploratory well does not find proved reserves, the costs of drilling the well are charged to expense. The costs of development wells arecapitalized whether productive or nonproductive. All capitalized well costs and other associated costs and leasehold costs of proved properties are amortizedon a unit-of-production basis over the remaining life of proved developed reserves and proved reserves, respectively.Costs of retired, sold or abandoned properties that constitute a part of an amortization base (partial field) are charged or credited, net of proceeds, toaccumulated depreciation, depletion and amortization unless doing so significantly affects the unit-of-production amortization rate for an entire field, inwhich case a gain or loss is recognized currently. Gains or losses from the disposal of properties are recognized currently.71 Table of ContentsExpenditures for maintenance, repairs and minor renewals necessary to maintain properties in operating condition are expensed as incurred. Majorbetterments, replacements and renewals are capitalized to the appropriate property and equipment accounts. Estimated dismantlement and abandonmentcosts for oil and natural gas properties are capitalized, net of salvage, at their estimated net present value and amortized on a unit-of-production basis over theremaining life of the related proved developed reserves.Unproved properties consist of costs incurred to acquire unproved leases, or lease acquisition costs. Unproved lease acquisition costs are capitalizeduntil the leases expire or when we specifically identify leases that will revert to the lessor, at which time we expense the associated unproved leaseacquisition costs. The expensing or expiration of unproved lease acquisition costs are recorded as abandonment or impairment of unproved properties in thestatements of operations and comprehensive income in our consolidated financial statements. Lease acquisition costs related to successful exploratorydrilling are reclassified to proved properties and depleted on a unit-of-production basis.For sales of entire working interests in unproved properties, gain or loss is recognized to the extent of the difference between the proceeds receivedand the net carrying value of the property. Proceeds from sales of partial interests in unproved properties are accounted for as a recovery of costs unless theproceeds exceed the entire cost of the property.Oil and natural gas reserve quantities and Standardized MeasureOur internal corporate reservoir engineering group prepares, and our third-party petroleum consultant audits our estimates of oil and natural gasreserves and associated future net revenues. While the SEC has adopted rules which allow us to disclose proved, probable and possible reserves, we haveelected to disclose only proved reserves in this Annual Report on Form 10-K. The SEC’s revised rules define proved reserves as the 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 contractsproviding the right to operate expire, unless evidence indicates that renewal is reasonably certain, regardless of whether deterministic or probabilisticmethods are used for the estimation. The project to extract the hydrocarbons must have commenced or the operator must be reasonably certain that it willcommence the project within a reasonable time. Our internal corporate reservoir engineering group and our third party petroleum consultant must make anumber of subjective assumptions based on their professional judgment in developing reserve estimates. Reserve estimates are updated annually andconsider recent production levels and other technical information about each field. Oil and natural gas reserve engineering is a subjective process ofestimating underground accumulations of oil and natural gas that cannot be precisely measured. The accuracy of any reserve estimate is a function of thequality of available data and of engineering and geological interpretation and judgment.Periodic revisions to the estimated reserves and future cash flows may be necessary as a result of a number of factors, including reservoirperformance, new drilling, oil and natural gas prices, cost changes, technological advances, new geological or geophysical data, or other economic factors.Accordingly, reserve estimates are generally different from the quantities of oil and natural gas that are ultimately recovered. We cannot predict the amountsor timing of future reserve revisions. If such revisions are significant, they could significantly affect future amortization of capitalized costs and result inimpairment of assets that may be material.Revenue recognitionRevenue from our interests in producing wells is recognized when the product is delivered, at which time the customer has taken title and assumedthe risks and rewards of ownership, and collectability is reasonably assured. The sales prices for oil and natural gas are adjusted for transportation and otherrelated deductions. These deductions are based on contractual or historical data and do not require significant judgment.Subsequently, these revenue deductions are adjusted to reflect actual charges based on third-party documents. Since there is a ready market for oiland natural gas, we sell the majority of production soon after it is produced at various locations.Impairment of proved propertiesWe review our proved oil and natural gas properties for impairment whenever events and circumstances indicate that a decline in the recoverabilityof their carrying value may have occurred and at least annually. We estimate the expected undiscounted future cash flows of our oil and natural gas propertiesand compare such undiscounted future cash flows to the carrying amount of the oil and natural gas properties to determine if the carrying amount isrecoverable. If the carrying amount exceeds the estimated undiscounted future cash flows, we will adjust the carrying amount of the oil and natural gasproperties to fair value. The factors used to determine fair value are subject to our judgment and expertise and include, but are not limited to, recent salesprices of comparable properties, the present value of future cash flows, net of estimated operating and72 Table of Contentsdevelopment costs using estimates of proved reserves, future commodity pricing, future production estimates, anticipated capital expenditures, and variousdiscount rates commensurate with the risk and current market conditions associated with realizing the expected cash flows projected. Because of theuncertainty inherent in these factors, we cannot predict when or if future impairment charges for proved properties will be recorded.Impairment of unproved propertiesWe assess our unproved properties periodically for impairment on a property-by-property basis based on remaining lease terms, drilling results orfuture plans to develop acreage and record abandonment and impairment expense for any decline in value.We have historically recognized abandonment and impairment expense for unproved properties at the time when the lease term has expired orsooner if, in management’s judgment, the unproved properties have lost some or all of their carrying value. We consider the following factors in ourassessment of the impairment of unproved properties:•the remaining amount of unexpired term under our leases;•our ability to actively manage and prioritize our capital expenditures to drill leases and to make payments to extend leases that may be closer toexpiration;•our ability to exchange lease positions with other companies that allow for higher concentrations of ownership and development;•our ability to convey partial mineral ownership to other companies in exchange for their drilling of leases; and•our evaluation of the continuing successful results from the application of completion technology in the Wattenberg Field by us or by otheroperators in areas adjacent to or near our unproved properties.The assessment of unproved properties to determine any possible impairment requires significant judgment.Asset retirement obligationsWe record the fair value of a liability for a legal obligation to retire an asset in the period in which the liability is incurred with the correspondingcost capitalized by increasing the carrying amount of the related long-lived asset. For oil and gas properties, this is the period in which the well is drilled oracquired. The asset retirement obligation (“ARO”) for oil and gas properties represents the estimated amount we will incur to plug, abandon and remediatethe properties at the end of their productive lives, in accordance with applicable state laws. The liability is accreted to its present value each period and thecapitalized cost is depreciated on the unit-of-production method. The accretion expense is recorded as a component of depreciation, depletion andamortization in our consolidated statements of operations and comprehensive income.We determine the ARO by calculating the present value of estimated cash flows related to the liability. Estimating the future ARO requiresmanagement to make estimates and judgments regarding timing, existence of a liability, as well as what constitutes adequate restoration. Inherent in the fairvalue calculation are numerous assumptions and judgments including the ultimate costs, inflation factors, credit-adjusted discount rates, timing of settlementand changes in the legal, regulatory, environmental and political environments. To the extent future revisions to these assumptions impact the fair value ofthe existing ARO liability, a corresponding adjustment is made to the related asset.DerivativesWe record all derivative instruments on the balance sheet as either assets or liabilities measured at their estimated fair value. We have not designatedany derivative instruments as hedges for accounting purposes and we do not enter into such instruments for speculative trading purposes. Derivativeinstruments are adjusted to fair value every accounting period. Derivative cash settlements and gains and losses from valuation changes in the remainingunsettled commodity derivative instruments are reported under derivative gain (loss) in our consolidated statements of operations and comprehensiveincome.Stock-based compensationRestricted Stock Awards. We recognize compensation expense for all restricted stock awards made to employees and directors. Stock-basedcompensation expense is measured at the grant date based on the fair value of the award and is recognized as an expense on a straight-line basis over therequisite service period, which is generally the vesting period. The73 Table of Contentsfair value of restricted stock grants is based on the value of our common stock on the date of grant. Stock-based compensation expense recorded for restrictedstock awards is included in general and administrative expenses on our consolidated statements of operations and comprehensive income.Performance Stock Units. We recognize compensation expense for all performance stock unit awards made to officers. Stock-based compensationexpense is measured at the grant date based on the fair value of the award and is recognized as expense on a straight-line basis over the requisite serviceperiod, which is generally the vesting period. The fair value of the performance stock unit is measured at the grant date with a stochastic process methodusing a Monte Carlo simulation. Stock-based compensation expense recorded for performance stock units is included in general and administrative expenseson our consolidated statements of operations and comprehensive income.Long Term Incentive Plan Units. We recognize compensation expense for all unit awards made to employees. Stock-based compensation expense ismeasured at the grant date based on the fair value of the award and is recognized as an expense on a straight-line basis over the requisite service period, whichis generally the vesting period. The fair value of unit awards is based on the value of our common stock on the date of grant. Stock-based compensationexpense recorded for unit awards is included in general and administrative expenses on our consolidated statements of operations and comprehensiveincome.Income taxesOur provision for taxes includes both federal and state taxes. We record our federal income taxes in accordance with accounting for income taxesunder GAAP which results in the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences betweenthe book carrying amounts and the tax basis of assets and liabilities. Deferred tax assets and liabilities are measured using enacted tax rates expected to applyto taxable income in the years in which those temporary differences and carryforwards are expected to be recovered or settled. The effect on deferred taxassets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance would beestablished to reduce deferred tax assets if it is more likely than not that the related tax benefits will not be realized.We apply significant judgment in evaluating our tax positions and estimating our provision for income taxes. During the ordinary course ofbusiness, there are many transactions and calculations for which the ultimate tax determination is uncertain. The actual outcome of these future taxconsequences could differ significantly from our estimates, which could impact our financial position, results of operations and cash flows.We also account for uncertainty in income taxes recognized in the financial statements in accordance with GAAP by prescribing a recognitionthreshold and measurement attribute for a tax position taken or expected to be taken in a tax return. Authoritative guidance for accounting for uncertainty inincome taxes requires that we recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would morelikely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financialstatements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. We did nothave any uncertain tax positions as of the year ended December 31, 2016.Recent accounting pronouncementsEffective January 1, 2015, the Company adopted, on a prospective basis, Financial Accounting Standards Board ("FASB") Accounting StandardsUpdate (“Update”) No. 2014-08 - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity. The update was aimed atreducing the frequency of disposals reported as discontinued operations by focusing on strategic shifts that have or will have a major effect on an entity’soperations and financial results. Subsequent to adoption of this guidance, the Company determined that assets that were deemed as held for sale during 2015did not qualify for discontinued operations. As such, the presentation within the accompanying balance sheets and the consolidated statements of operationsand comprehensive income reflect them as standard assets held for sale versus our California asset sales that occurred in 2014 and 2012 that were presented asdiscontinued operations. For additional discussion, please refer to Note 2 - Acquisitions and Divestitures and Note 3 - Assets Held for Sale.Effective January 1, 2016, the Company adopted, on a retrospective basis, FASB Update No. 2015-02, Consolidation (Topic 810): Amendments tothe Consolidation Analysis.

There are no other accounting standards applicable to the Company that would have a material effect on the Company’s financial statements anddisclosures that have been issued but not yet adopted by the Company as of December 31, 2016, and through the filing date of this report.76 Table of ContentsEffects of Inflation and Pricing Inflation in the United States increased to 2.2% in 2016 from 2.0% in 2015 and from 1.3% in 2014, which did not have a material impact on ourresults of operations for the periods ended December 31, 2016, 2015 and 2014. Although the impact of inflation has been relatively insignificant in recentyears, it is still a factor in the United States economy and we tend to experience inflationary pressure on the cost of oilfield services and equipment asincreasing oil and gas prices increase drilling activity in our areas of operations. Material changes in prices also impact the current revenue stream, estimatesof future reserves, borrowing base calculations, depletion expense, impairment assessments of oil and gas properties, ARO, and values of properties inpurchase and sale transactions. Material changes in prices can impact the value of oil and gas companies and their ability to raise capital, borrow money andretain personnel.Off-Balance Sheet Arrangements Currently, we do not have any off-balance sheet arrangements.Item 7A. Quantitative and Qualitative Disclosures About Market Risks.Oil and Natural Gas Price RiskOur financial condition, results of operations and capital resources are highly dependent upon the prevailing market prices of oil and natural gas.These commodity prices are subject to wide fluctuations and market uncertainties due to a variety of factors that are beyond our control. Factors influencingoil and natural gas prices include the level of global demand for oil and natural gas, the global supply of oil and natural gas, the establishment of andcompliance with production quotas by oil exporting countries, weather conditions which determine the demand for natural gas, the price and availability ofalternative fuels, local and global politics, and overall economic conditions. It is impossible to predict future oil and natural gas prices with any degree ofcertainty. Sustained weakness in oil and natural gas prices may adversely affect our financial condition and results of operations, and may also reduce theamount of oil and natural gas reserves that we can produce economically. Any reduction in our oil and natural gas reserves, including reductions due to pricefluctuations, can have an adverse effect on our ability to obtain capital for our exploration and development activities. Similarly, any improvements in oiland natural gas prices can have a favorable impact on our financial condition, results of operations and capital resources. If oil and natural gas SEC pricesdeclined by 10% then our proved reserve volumes would decrease by 8% and our PV-10 value as of December 31, 2016 would decrease by approximately42% or $116.2 million. The PV-10 value of our Rocky Mountain region, primarily our Wattenberg assets, would decrease by 48% or $97.5 million.PV-10 is a non-GAAP financial measure. Please refer to Estimated Proved Reserves under Part I, Item 1 of this Annual Report on Form 10-K formanagement's discussion of this non-GAAP financial measure.In the past, we have entered into various types of derivative instruments, including commodity price swaps, costless collars, put options, and basisprotection swaps to mitigate a portion of our exposure to fluctuations in commodity prices. Our debt defaults and the commencement of our Chapter 11 Caseswere events of default under our derivative master agreements thereby providing our derivative counterparties the right to terminate all our derivativepositions. As a result, all derivative positions were terminated in the fourth quarter of 2016.Interest RatesAt December 31, 2016 and through the filing date of this report we had $191.7 million outstanding under our revolving credit facility. Borrowingsunder our revolving credit facility bear interest at a fluctuating rate that is tied to an adjusted Base Rate or LIBOR, at our option. Any increases in theseinterest rates can have an adverse impact on our results of operations and cash flow. As of December 31, 2016 and through the filing date of this report, theCompany was and is in default and currently bears interest on the amount drawn at the Bank Prime Rate plus the utilization margin plus a 2% fee.Counterparty and Customer Credit RiskIn connection with our derivatives activity, we have exposure to financial institutions in the form of derivative transactions. We do not currentlyhave any derivative instruments in place, however, we expect that any future derivative transactions we enter into will be with lenders under our creditfacility that will carry an investment grade credit rating.We are also subject to credit risk due to concentration of our oil and natural gas receivables with certain significant customers. Please refer to thesection titled Principal Customers under Part I, Item 1 of this Annual Report on Form 10-K for further details about our significant customers. The inability orfailure of our significant customers to meet their obligations to77 Table of Contentsus or their insolvency or liquidation may adversely affect our financial results. We review the credit rating, payment history and financial resources of ourcustomers, but we do not require our customers to post collateral.Marketability of Our ProductionThe marketability of our production from the Mid-Continent and Rocky Mountain regions depends in part upon the availability, proximity andcapacity of third-party refineries, access to regional trucking, pipeline and rail infrastructure, natural gas gathering systems and processing facilities. Wedeliver crude oil and natural gas produced from these areas through trucking services, pipelines and rail facilities that we do not own. The lack of availabilityor capacity on these systems and facilities could reduce the price offered for our production or result in the shut-in of producing wells or the delay ordiscontinuance of development plans for properties.A portion of our production may also be interrupted, or shut in, from time to time for numerous other reasons, including as a result of accidents, fieldlabor issues or strikes, or we might voluntarily curtail production in response to market conditions. If a substantial amount of our production is interrupted atthe same time, it could adversely affect our cash flow.Currently, there are no natural gas pipeline systems that service wells in the North Park Basin, which is prospective for the Niobrara shale. Inaddition, we are not aware of any plans to construct a facility necessary to process natural gas produced from this basin. If neither we nor a third-partyconstructs the required pipeline system and processing facility, we may not be able to fully test or develop our resources in the North Park Basin.78 Table of ContentsItem 8. Financial Statements and Supplementary DataREPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Board of Directors and StockholdersBonanza Creek Energy, Inc.We have audited the accompanying consolidated balance sheets of Bonanza Creek Energy, Inc. and subsidiaries as of December 31, 2016 and 2015, and therelated consolidated statements of operations and comprehensive income, stockholders’ equity and cash flows for each of the three years in the period endedDecember 31, 2016. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on thesefinancial statements based on our audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includesexamining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accountingprinciples used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our auditsprovide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Bonanza Creek Energy,Inc. and subsidiaries as of December 31, 2016 and 2015, and the results of their operations and their cash flows for each of the three years in the period endedDecember 31, 2016, in conformity with U.S. generally accepted accounting principles.The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to thefinancial statements, the Company suffered a significant deterioration in liquidity during 2016, and filed for bankruptcy under Chapter 11 of the BankruptcyCode on January 4, 2017. This raises substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to thesematters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Bonanza Creek Energy, Inc.’sand subsidiaries’ internal control over financial reporting as of December 31, 2016, based on criteria established in Internal Control - Integrated Frameworkissued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated March 15, 2017 expressed an unqualifiedopinion on the effectiveness of Bonanza Creek Energy, Inc.’s internal control over financial reporting.Hein & Associates LLPDenver, ColoradoMarch 15, 2017 79 Table of ContentsBONANZA CREEK ENERGY, INC.

AND SUBSIDIARIESNOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of OperationsBonanza Creek Energy, Inc. (“BCEI” or, together with its consolidated subsidiaries, the “Company”) is engaged primarily in acquiring, developing,exploiting and producing oil and gas properties. As of December 31, 2016, the Company’s assets and operations were concentrated primarily in theWattenberg Field in Colorado and in the Dorcheat Macedonia Field in southern Arkansas.Basis of PresentationThe consolidated balance sheets include the accounts of the Company and its wholly owned subsidiaries, Bonanza Creek Energy OperatingCompany, LLC, Bonanza Creek Energy Resources, LLC, Bonanza Creek Energy Upstream LLC, Bonanza Creek Energy Midstream, LLC, Holmes EasternCompany, LLC and Rocky Mountain Infrastructure, LLC. All significant intercompany accounts and transactions have been eliminated. In connection withthe preparation of the consolidated financial statements, the Company evaluated subsequent events after the balance sheet date of December 31, 2016,through the filing date of this report.Use of EstimatesThe preparation of the Company’s consolidated financial statements in conformity with accounting principles generally accepted in the UnitedStates of America requires management to make estimates and assumptions that affect the reported amounts of oil and gas reserves, assets and liabilities, anddisclosure of contingent assets and liabilities at the date of the balance sheet and the reported amounts of revenue and expenses during the reporting period.Actual results could differ from those estimates.Going Concern UncertaintySince the first quarter of 2016, the Company’s liquidity outlook has deteriorated due to a significant reduction in operating cash flow, theCompany's inability to sell assets given current market conditions and counterparty concerns about the Company's liquidity and current capital structure,borrowing base reductions that occurred during 2016, continuation of depressed commodity prices and the inability to access the debt and capital markets. Inaddition, the Company’s senior secured revolving credit agreement (the “revolving credit facility”) is subject to scheduled redeterminations of its borrowingbase, semi-annually, as early as April and October of each year, based primarily on reserve report values using lender commodity price expectations at suchtime as well as other factors within the discretion of the lenders that are party to the revolving credit facility.As a result of these and other factors, the following issues have adversely impacted the Company’s ability to continue as a going concern:•the Company’s ability to comply with financial covenants and ratios in its revolving credit facility and indentures has been affected by continuedlow commodity prices. Among other things, the Company is required under its revolving credit facility to maintain a minimum interest coverageratio that must exceed 2.50 to 1.00 and a maximum debt ratio that must not exceed 2.50 to 1.00. Absent a waiver, amendment or forbearanceagreement, failure to meet these covenants and ratios would result in an Event of Default (as defined in the revolving credit agreement) and, to theextent the applicable lenders so elect, an acceleration of the Company’s existing indebtedness. As of December 31, 2016, and through the filing dateof this report, the Company was no longer in compliance with its minimum interest coverage and maximum debt ratio requirements. The Companyentered into a Restructuring Support Agreement (“RSA”) on December 23, 2016 and filed for bankruptcy under Chapter 11 of the Bankruptcy Codeon January 4, 2017. The applicable lenders did not elect to accelerate the Company's debt prior to filing for bankruptcy. The Company was grantedan automatic stay from collection efforts upon filing for bankruptcy. Please refer to Note 19 - Subsequent Events for more on our bankruptcyproceedings;•because the revolving credit facility borrowing base was reduced in May 2016 to $200.0 million, the Company was overdrawn by $88.0 million andmade six mandatory monthly repayments of approximately $14.7 million. The borrowing base was further reduced on October 31, 2016 to $150.0million, causing the Company to be overdrawn by85 Table of Contents$50.0 million, and the Company elected to make mandatory monthly repayments of $8.3 million. Due to the timing of filing for Chapter 11, theCompany did not make the monthly repayment due on December 30, 2016, or any subsequent payments, and has been granted a stay from makingany further deficiency payments while under the protection of Chapter 11;•the Company’s ability to make interest payments as they become due and repay indebtedness upon maturities is impacted by the Company’sliquidity. As of December 31, 2016, the Company faces a $41.7 million borrowing base deficiency under its revolving credit facility and has $80.6million in cash and cash equivalents;•the Company has two purchase and transportation agreements to deliver fixed determinable quantities of crude oil. The first agreement with SiloEnergy, LLC (“Silo”) went into effect during the second quarter of 2015 for 12,580 barrels per day over an initial five-year term. The Company hasincurred $3.4 million in minimum volume commitment deficiency payments related to this agreement as of December 31, 2016. Based on currentproduction estimates, assuming no future drilling and completion activity, the anticipated shortfall in delivering the minimum volume commitmentscould result in potential deficiency payments of $44.8 million for 2017 through April 2020, when the agreement expires. Subject to bankruptcycourt confirmation, the Company terminated its purchase agreement with Silo on February 1, 2017 and entered into a settlement agreement pursuantto which Silo will receive value of approximately $21.0 million. The second purchase agreement with NGL Crude Logistics, LLC (“NGL”) becameeffective on November 1, 2016 for 15,000 barrels per day over an initial seven-year term. Based on current production estimates at December 31,2016, assuming no future drilling and completion activity, the anticipated shortfall in delivering the minimum volume commitments could result inpotential deficiency payments of $165.2 million for 2017 through October 2023, when the second agreement expires. The NGL purchase agreementis contemplated to be amended as part of the RSA. Please refer to Note 8 - Commitments and Contingencies for additional discussion; and•if the revolving credit facility is accelerated, then an Event of Default (as defined in the underlying indentures) under the Company's 6.75% SeniorNotes due 2021 (“6.75% Senior Notes”) and 5.75% Senior Notes due 2023 (“5.75% Senior Notes”, and together with the 6.75% Senior Notesreferred to as the “Senior Notes”) would occur. If an Event of Default occurs, the trustee or the holders of at least 25% in aggregate principal amountof the then outstanding notes, may declare the entire principal under the Senior Notes to be due and payable immediately. The revolving creditfacility and Senior Notes have cross default clauses. Filing for protection under Chapter 11 of the Bankruptcy Code is an event of default under ourrevolving credit facility and Senior Notes. Upon filing for bankruptcy under Chapter 11, the Company was granted a stay from collection efforts. Asof December 31, 2016, the revolving credit facility and Senior Notes had not been accelerated.Due to covenant violations, the Company classified the revolving credit facility and Senior Notes as current liabilities in the December 31, 2016accompanying balance sheets.The Company has taken steps to rectify its going concern uncertainty. The Company has filed for bankruptcy under Chapter 11 under theBankruptcy Code and has entered into an RSA which if approved contemplates a $200.0 million rights offering allowing the Company to operate a one-rigprogram upon emergence from bankruptcy.The significant risks and uncertainties described above raise substantial doubt about the Company’s ability to continue as a going concern. Theconsolidated financial statements have been prepared on a going concern basis of accounting, which contemplates continuity of operations, realization ofassets, and satisfaction of liabilities and commitments in the normal course of business. The consolidated financial statements do not include any adjustmentsthat might result from the outcome of the going concern uncertainty or the outcome of the Chapter 11 filing. There is no guarantee that post emergence frombankruptcy the Company will be a going concern.See Note 7 - Long-Term Debt, Note 8 - Commitment and Contingencies and Note 19 - Subsequent Events for additional details about the Company’sdebt, commitments and bankruptcy proceedings.Cash and Cash EquivalentsThe Company considers all highly liquid investments with original maturity dates of three months or less to be cash equivalents. The carrying valueof cash and cash equivalents approximate fair value due to the short-term nature of these instruments.86 Table of ContentsAccounts ReceivableThe Company’s accounts receivables are generated from oil and gas sales and from joint interest owners on properties that the Company operates.The Company accrues an allowance on a receivable when, based on the judgment of management, it is probable that a receivable will not be collected andthe amount of any allowance may be reasonably estimated. For receivables from joint interest owners, the Company usually has the ability to withhold futurerevenue disbursements to satisfy the outstanding balance. The Company’s oil and gas receivables are typically collected within one to two months and theCompany has experienced minimal bad debts.Inventory of Oilfield EquipmentInventory consists of material and supplies used in connection with the Company’s drilling program. These inventories are stated at the lower of costor market, which approximates fair value.Oil and Gas Producing ActivitiesThe Company follows the successful efforts method of accounting for its oil and gas exploration and development costs. Under this method ofaccounting, all property acquisition costs and costs of exploratory and development wells will be capitalized at cost when incurred, pending determination ofwhether economically recoverable reserves have been found. If an exploratory well does not find economically recoverable reserves, the costs of drilling thewell and other associated costs are charged to dry hole expense. The costs of development wells are capitalized whether the well is productive ornonproductive. Costs incurred to maintain wells and their related equipment and leases as well as operating costs are charged to expense as incurred.Geological and geophysical costs are expensed as incurred.Depletion, depreciation and amortization (“DD&A”) of capitalized costs of proved oil and gas properties are provided for on a field-by-field basisusing the units-of-production method based upon proved reserves. The computation of DD&A takes into consideration restoration, dismantlement, andabandonment costs and anticipated proceeds from salvaging equipment.The Company assesses its proved oil and gas properties for impairment whenever events or circumstances indicate that the carrying value of theassets may not be recoverable. The impairment test compares undiscounted future net cash flows to the assets net book value. If the net capitalized costsexceed future net cash flows, then the cost of the property is written down to fair value. The factors used to determine fair value are subject to the Company’sjudgment and expertise and include, but are not limited to, recent sales prices of comparable properties, the present value of future cash flows on alldeveloped proved reserves and risk adjusted probable and possible reserves, net of estimated operating and development costs, future commodity pricingbased on our internal budgeting model originating from the NYMEX strip price adjusted for basis differential, future production estimates, anticipated capitalexpenditures, and various discount rates commensurate with the risk and current market conditions associated with realizing the expected cash flowsprojected.The Company assesses its unproved properties periodically for impairment on a property-by-property basis, which requires significant judgment.The Company considers the following factors in its assessment of the impairment of unproved properties:•the remaining amount of unexpired term under leases;•its ability to actively manage and prioritize its capital expenditures to drill leases and to make payments to extend leases that may be closer toexpiration;•its ability to exchange lease positions with other companies that allow for higher concentrations of ownership and development;•its ability to convey partial mineral ownership to other companies in exchange for their drilling of leases;•its evaluation of the continuing successful results from the application of completion technology by the Company or by other operators in areasadjacent to or near its unproved properties;•its evaluation of the current fair market value of acreage; and•strategic shifts in development areas.87 Table of ContentsFor additional discussion, please refer to Note 4 - Impairments.The Company records the fair value of an asset retirement obligation as an asset and a liability when there is a legal obligation associated with theretirement of a long-lived asset and the amount can be reasonably estimated. The increase in carrying value is included in proved properties in theaccompanying consolidated balance sheets (“accompanying balance sheets”). For additional discussion, please refer to Note 11 - Asset RetirementObligations.Gains and losses arising from sales of oil and gas properties will be included in income. However, a partial sale of proved properties within anexisting field that does not significantly affect the unit-of-production depletion rate will be accounted for as a normal retirement with no gain or lossrecognized. The sale of a partial interest within a proved property is accounted for as a recovery of cost. The partial sale of unproved property is accounted foras a recovery of cost when there is uncertainty of the ultimate recovery of the cost applicable to the interest retained.Natural Gas PlantsNatural gas plants are recorded at cost and are deemed part of the upstream oil and gas producing activities of the Company as they primarily serveCompany wells and have limited viability on their own. The natural gas plants are depleted on a units-of-production method.Other Property and EquipmentOther property and equipment such as office furniture and equipment, buildings, and computer hardware and software are recorded at cost. Cost ofrenewals and improvements that substantially extend the useful lives of the assets are capitalized. Maintenance and repair costs are expensed as incurred.Depreciation is calculated using the straight-line method over the estimated useful lives of the assets, which range from three to ten years.Assets Held for SaleAssets are classified as held for sale when the Company commits to a plan to sell the assets and there is reasonable certainty that the sale will takeplace within one year. Upon classification as held for sale, long-lived assets are no longer depreciated or depleted, and a measurement for impairment isperformed to identify and expense any excess of carrying value over fair value less estimated costs to sell. Any subsequent decreases to the estimated fairvalue less the costs to sell impact the measurement of assets held for sale. Any properties deemed held for sale as of the balance sheet date are presentedseparately on the accompanying balance sheets at the lower of net book value or fair value less cost to sell. For additional discussion, please refer to Note 3 -Assets Held for Sale.Revenue RecognitionThe Company records revenues, net of royalties, discounts, and allowances, as applicable, from the sales of crude oil, natural gas and natural gasliquids (“NGLs”) when delivery to the customer has occurred and title has transferred. This occurs when oil or gas has been delivered to a pipeline or a tanklifting has occurred. At the end of each month, the Company estimates the amount of production delivered to the purchaser and the price the Company willreceive. The Company factors in historical performance, quality and transportation differentials, commodity prices, and other factors when deriving revenueestimates. Payment is generally received within 30 to 90 days after the date of production. The Company has interests with other producers in certainproperties in which case the Company uses the entitlement method to account for gas imbalances. The Company had no material gas imbalances as ofDecember 31, 2016 and 2015.For gathering and processing services, the Company either receives fees or commodities from natural gas producers depending on the type ofcontract. Under the percentage-of-proceeds contract type, the Company is paid for its services by keeping a percentage of the NGLs produced and apercentage of the residue gas resulting from processing the natural gas. Commodities received are, in turn, sold and recognized as revenue in accordance withthe criteria outlined above.Income TaxesThe Company accounts for income taxes under the liability method, which requires recognition of deferred tax assets and liabilities for the expectedfuture tax consequences of events that have been included in the balance sheet or tax returns. Under this method, deferred tax assets and liabilities aredetermined based on the difference between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year inwhich the differences are expected to reverse.88 Table of ContentsUncertain Tax PositionsThe Company recognizes interest and penalties related to uncertain tax positions in income tax expense. The tax returns for 2015, 2014 and 2013are still subject to audit by the Internal Revenue Service. There were no uncertain tax positions.Concentrations of Credit RiskThe Company maintains cash balances in excess of the Federal Deposit Insurance Corporation (FDIC) insured limit.The Company is exposed to credit risk in the event of nonpayment by counterparties whose creditworthiness is continuously evaluated. For theyears ended December 31, 2016 and 2015 Silo Energy Company accounted for 50% and 31%, respectively, Lion Oil Trading & Transportation, Inc.accounted for 18% and 16%, respectively, Plains Marketing LP accounted for 0% and 11%, respectively, and Duke Energy Field Services accounted for 14%and 11%, respectively, of our oil and natural gas sales. For the year ended December 31, 2014, Plains Marketing LP accounted for 29%, Lion Oil Trading &Transportation, Inc. accounted for 19%, and High Sierra Crude Oil & Marketing accounted for 11% of our oil and natural gas sales.Oil and Gas Derivative ActivitiesThe Company is exposed to commodity price risk related to oil and gas prices. To mitigate this risk, the Company enters into oil and gas forwardcontracts. The contracts, which were generally placed with major financial institutions or with counterparties which management believes to be of high creditquality, may take the form of futures contracts, swaps, options, or collars. The oil contracts are indexed to NYMEX WTI prices, and natural gas contracts areindexed to NYMEX HH prices, which have a high degree of historical correlation with actual prices received by the Company, before differentials. TheCompany recognizes all derivative instruments on the balance sheet as either assets or liabilities at fair value. For additional discussion, please refer toNote 13 - Derivatives.Earnings Per ShareEarnings per basic and diluted share are calculated under the two-class method. Pursuant to the two-class method, the Company’s unvested restrictedstock awards with non-forfeitable rights to dividends are considered participating securities. Under the two-class method, earnings per basic share iscalculated by dividing net income available to shareholders by the weighted-average number of common shares outstanding during the period. The two-classmethod includes an earnings allocation formula that determines earnings per share for each participating security according to undistributed earnings for theperiod. Net income available to shareholders is reduced by the amount allocated to participating restricted shares to arrive at the earnings allocated tocommon stock shareholders for purposes of calculating earnings per share. Participating shares are not contractually obligated to share in the losses of theCompany, and therefore, the entire net loss is allocated to the outstanding shares. Earnings per diluted share is computed on the basis of the weighted-averagenumber of common shares outstanding during the period plus the dilutive effect of any potential common shares outstanding during the period using themore dilutive of the treasury method or two-class method. In periods of net loss, shares that are dilutive become anti-dilutive. For additional discussion,please refer to Note 14 - Earnings Per Share.Stock-Based CompensationThe Company measures the cost of employee services received in exchange for an award of equity instruments based on the grant-date fair value ofthe award. For additional discussion, please refer to Note 9 - Stock-Based Compensation.Fair Value of Financial InstrumentsThe Company’s financial instruments consist of cash and cash equivalents, trade receivables, trade payables, accrued liabilities, revolving creditfacility, senior notes, and derivative instruments. Cash and cash equivalents, trade receivables, trade payables and accrued liabilities are carried at cost andapproximate fair value due to the short-term nature of these instruments. Our revolving credit facility has a variable interest rate so it approximates fair value.Our senior notes are recorded at cost, and their fair value is disclosed within Note 12 - Fair Value Measurements. Derivative instruments are recorded at fairvalue. The book value of the contractual obligation for land acquisition approximates fair value due to it being discounted at a market-based interest rate.89 Table of ContentsPrior Year ReclassificationsCertain prior year balances have been reclassified to conform to the current year presentation, and such reclassifications had no impact on netincome (loss) or stockholders’ equity previously reported.Recently Issued and Adopted Accounting StandardsEffective January 1, 2015, the Company adopted, on a prospective basis, Financial Accounting Standards Board ("FASB") Accounting StandardsUpdate (“Update”) No. 2014-08 - Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity.

The Company paid approximately $12.0 million at closing and $12.0 million in each of July 2013, July 2014, July2015, and May 2016.Discontinued OperationsDuring June 2012, the Company sold the majority of its oil and gas properties in California classifying them as discontinued operations with itsremaining property being sold in the first quarter of 2014 for approximately $6.0 million. The Company recorded a gain on sale of oil and gas properties inthe amount of $5.5 million for the year ended December 31, 2014.NOTE 3 - ASSETS HELD FOR SALEAs of December 31, 2015, the accompanying balance sheets present $214.9 million of assets held for sale, net of accumulated depreciation,depletion and amortization, which consists of the Company’s Rocky Mountain Infrastructure, LLC subsidiary (“RMI”), all assets within the Company's Mid-Continent region and all assets in the North Park Basin. There is a corresponding asset retirement obligation liability of approximately $10.6 million forassets held for sale recorded in the asset retirement obligations for assets held for sale financial statement line item in the accompanying balance sheets.

Please refer to the going concern uncertainty subsection inNote 1 - Summary of Significant Accounting Policies and Note 19 - Subsequent Events for additional discussion.Revolving Credit Facility The revolving credit facility, dated March 29, 2011, as amended, with a syndication of banks, provides for a total credit facility size of $1.0 billion.The revolving credit facility provides for interest rates plus an applicable margin to be determined based on LIBOR or a base rate, at the Company’s election.LIBOR borrowings bear interest at LIBOR plus 1.50% to 2.50% depending on the utilization level, and the base rate borrowings bear interest at the “BankPrime Rate,” as defined in the revolving credit facility, plus 0.50% to 1.50%. The applicable lenders under the revolving credit facility deemed the Companyin default due to a covenant violation on November 14, 2016 causing the then outstanding balance under the revolving credit facility to bear interest at theBank Prime Rate plus the applicable utilization margin and 2% penalty fee.The borrowing base on the revolving credit facility was reduced on May 20, 2016 from $475.0 million to $200.0 million, and was further reducedfrom $200.0 million to $150.0 million on October 31, 2016. The borrowing base is redetermined semiannually, as early as April and October of each year.The revolving credit facility is collateralized by substantially all of the Company’s assets and matures on September 15, 2017. As of December 31, 2016, theCompany had $191.7 million outstanding under the revolving credit facility and had a borrowing base deficiency of $41.7 million to be paid back in fiveremaining monthly installments of $8.3 million, with no additional available borrowing capacity. The Company filed for bankruptcy under Chapter 11 of theBankruptcy Code on January 4, 2017, granting the Company a stay from making any further deficiency payments.The revolving credit facility restricts, among other items, certain dividend payments, additional indebtedness, asset sales, loans, investments andmergers. The revolving credit facility also contains certain financial covenants, which require the maintenance of certain financial and leverage ratios, asdefined by the revolving credit facility. The revolving credit facility contains a ratio of maximum senior secured debt to trailing twelve-month EBITDAX(defined as earnings before interest expense, income tax expense, depreciation, depletion and amortization expense, and exploration expense and other non-cash charges) that must not exceed 2.50 to 1.00 and a minimum interest coverage ratio that must exceed 2.50 to 1.00. The maximum senior secured debt ratiois calculated by dividing borrowings under the revolving credit facility, balances drawn under letters of credit, and any outstanding second lien debt dividedby trailing twelve-month EBITDAX. The minimum interest coverage ratio is calculated by dividing trailing twelve-month EBITDAX by trailing twelve-month interest expense. The revolving credit facility also contains a minimum current ratio covenant of 1.00 to 1.00. The revolving credit facility agreementstates that the current ratio is to exclude the current portion of long-term debt, as such the classification of the Company's long-term debt to current liabilitiesdid not impact the current ratio. The Company is no longer in compliance with its minimum interest coverage or maximum debt ratio requirements thusallowing the applicable lenders to give notice of acceleration as a result of this non-compliance. As of December 31, 2016, the Company had not received anotice of acceleration.5.75% Senior Notes94 Table of ContentsOn July 15, 2014, the Company issued $300.0 million aggregate principal amount of 5.75% Senior Notes that mature on February 1, 2023. Intereston the 5.75% Senior Notes began accruing on July 15, 2014, and interest is payable on February 1 and August 1 of each year, beginning on February 1, 2015.The 5.75% Senior Notes are guaranteed on a senior unsecured basis by the Company’s existing and future subsidiaries that incur or guarantee certainindebtedness, including indebtedness under the revolving credit facility. The net proceeds from the sale of the 5.75% Senior Notes were $293.4 million afterdeductions of $6.6 million of expenses and underwriting discounts and commissions.At any time prior to August 1, 2017, subject to certain limitations, the Company may redeem up to 35% of the aggregate principal amount of the5.75% Senior Notes at a redemption price of 105.75% of the principal amount, plus accrued and unpaid interest, with an amount of cash not greater than thenet cash proceeds of an equity offering.

Interest onthe Senior Notes began accruing on April 9, 2013, and interest is payable on April 15 and October 15 of each year, which began on October 15, 2013. OnNovember 15, 2013, the Company issued an additional $200.0 million aggregate principal amount of 6.75% Senior Notes as an additional issuance of itsexisting 6.75% Senior Notes. The 6.75% Senior Notes are guaranteed on a senior unsecured basis by the Company’s existing and future subsidiaries thatincur or guarantee certain indebtedness, including indebtedness under the Company’s revolving credit facility. The net proceeds from the sale of the 6.75%Senior Notes were $496.7 million after the premium and deduction of $12.3 million of expenses and underwriting discounts and commissions.The Company may redeem all or a part of the 6.75% Senior Notes at any time prior to April 15, 2017 at the redemption price equal to 100% of theprincipal amount, plus the applicable “make-whole” premium and accrued and unpaid interest. On or after April 15, 2017, the Company may redeem all or apart of the 6.75% Senior Notes at the redemption price of 103.375% for 2017, 101.688% for 2018, and 100.0% for 2019 and thereafter, during the twelve-month period beginning on April 15 of each applicable year, plus accrued and unpaid interest.On November 12, 2013 and July 15, 2014, the Company filed automatic registration statements on Form S‑3 to register the 5.75% Senior Notes and6.75% Senior Notes, respectively, and guarantees of the Senior Notes. As of December 31, 2016, all of the existing subsidiaries of the Company areguarantors of the Senior Notes, and all such subsidiaries are 100% owned by the Company. The guarantees by the subsidiaries are full and unconditional(except for customary release provisions) and constitute joint and several obligations of the subsidiaries. The Company has no independent assets oroperations unrelated to its investments in its consolidated subsidiaries. There are no significant restrictions on the Company’s ability or the ability of anysubsidiary guarantor to obtain funds from its subsidiaries by such means as a dividend or loan.The revolving credit facility and Senior Notes have cross default clauses. The noteholders had the option to give notice of acceleration as of year-end. The Company did not receive a notice of acceleration from the noteholders.Please refer to Note 19 - Subsequent Events for additional discussion about the Company's bankruptcy proceedings.95 Table of ContentsNOTE 8 - COMMITMENTS AND CONTINGENCIESLegal Proceedings From time to time, the Company is involved in various commercial and regulatory claims, litigation and other legal proceedings that arise in theordinary course of its business. The Company assesses these claims in an effort to determine the degree of probability and range of possible loss for potentialaccrual in its consolidated financial statements. In accordance with accounting authoritative guidance, an accrual is recorded for a loss contingency when itsoccurrence is probable and damages can be reasonably estimated based on the most likely anticipated outcome or the minimum amount within a range ofpossible outcomes. Because legal proceedings are inherently unpredictable and unfavorable resolutions could occur, assessing contingencies is highlysubjective and requires judgments about uncertain future events. When evaluating contingencies, the Company may be unable to provide a meaningfulestimate due to a number of factors, including the procedural status of the matter in question, the presence of complex or novel legal theories, and/or theongoing discovery and development of information important to the matters. The Company regularly reviews contingencies to determine the adequacy of itsaccruals and related disclosures. No claims have been made, nor is the Company aware of any material uninsured liability which the Company may have, as itrelates to any environmental cleanup, restoration or the violation of any rules or regulations. As of the filing date of this report, there were no materialpending or overtly threatened legal actions against the Company of which it is aware.In February 2017, the Colorado Department of Public Health and Environment (“CDPHE”) proposed settlement terms under which the Companywould be required to pay an administrative penalty in excess of $100,000 and perform certain mitigation projects and adopt certain procedures and processesaddressing the monitoring, reporting, and reduction of emissions with respect to the Company’s storage tank facilities in the Wattenberg Field. The Companybelieves that the terms of settlement offered to the Company are part of a broader enforcement initiative the CDPHE is taking with multiple operators in theWattenberg Field.Although the Company intends to continue working with the CDPHE in an attempt to reach a consensual resolution of the relevant compliancematters, the Company firmly believes that the proposed terms of settlement are neither mandated by the applicable air quality regulations nor consistent withthe Company’s historical practices or its rights under the Environmental Audit Law. It is not possible to determine at this time whether the Company willultimately be subject to any civil penalty assessment in connection with the resolution of compliance issues identified in the Audit and the ComplianceAdvisory.For discussion of our ongoing bankruptcy proceedings please see Note 19 - Subsequent Events.CommitmentsIn October 2014, the Company entered into two purchase agreements to deliver fixed determinable quantities of crude oil. The first agreement withSilo went into effect during the second quarter of 2015 for 12,580 barrels per day over an initial five-year term. While the volume commitment may be metwith Company volumes or third-party volumes, delegated by the Company, the Company will be required to make periodic deficiency payments for anyshortfalls in delivering the minimum volume commitments. The Company incurred $3.4 million as of December 31, 2016 in deficiency payments to Silo onthe minimum volume commitments. Based on current production estimates, assuming no future drilling and completion activity, the anticipated shortfall indelivering the minimum volume commitments could result in potential deficiency payments of $44.8 million for 2017 through April 2020, when theagreement expires. Subject to bankruptcy court confirmation, the Company terminated its purchase agreement with Silo on February 1, 2017, and enteredinto a settlement agreement pursuant to which Silo will receive value of approximately $21.0 million. The estimated settlement allows Silo (i) to retain the$5.0 million adequate assurance deposit it currently maintains, (ii) to retain the Company's $8.7 million crude oil revenue receivable due to the Company forDecember 2016 production, (iii) to receive an additional cash payment of $4.5 million on the date of emergence from bankruptcy, and (iv) to receive a $2.7million payment to be settled in equity or cash on the date of emergence from bankruptcy. The $21.0 million settlement is shown in the contract settlementexpense line item in the accompanying statements of operations as of December 31, 2016.The second purchase agreement, with NGL, took effect in the fourth quarter of 2016 for 15,000 barrels per day over an initial seven-year term. Basedon current production estimates, assuming no future drilling and completion activity, the anticipated shortfall in delivering the minimum volumecommitments could result in potential deficiency payments of $165.2 million for 2017 through October 2023, when the agreement expires.96 Table of ContentsThe NGL purchase agreement is contemplated to be amended pursuant to the RSA, which is subject to bankruptcy court confirmation. Theamendment waives any existing and future deficiency payments throughout 2017. The terms of the amended NGL purchase agreement consists of an agreedupon one-rig program volume commitment not to exceed 20,000 barrels per day for a term commencing upon our emergence from bankruptcy and expiringon December 31, 2023. The Company does not anticipate incurring deficiencies once the contemplated minimum volume commitments go into affect in2018. The aggregate financial commitment fee, assuming the maximum commitment volumes and base differential, is $246.4 million as of January 1, 2017. Please refer to Note 19 - Subsequent Events for additional discussion on the Company's bankruptcy proceedings. The Company rents office facilities under various non-cancelable operating lease agreements.

Rent expense for the years ended December 31, 2016, 2015 and 2014 was $2.8 million, $2.6million and $2.0 million, respectively. The Company has filed with the Bankruptcy Court to reject its Denver office lease, as permitted under the BankruptcyCode, and enter into a new office lease agreement that would extend through February 2022. We currently sublease a portion of our Denver office lease,pursuant to which, the Company would receive a total of $2.1 million payable through 2020.NOTE 9 - STOCK-BASED COMPENSATIONManagement Incentive PlanOn December 23, 2010, the Company established the Management Incentive Plan (the “Plan”) for the benefit of certain employees, officers andother individuals performing services for the Company. The maximum number of shares of Class B common stock available under the Plan was 10,000 andthese shares were converted into 437,787 shares of our restricted common stock upon completion of the Company’s initial public offering. The conversionrate was determined based on a formula factoring in the rate of return to the pre-IPO common stockholders. The 437,787 shares of common stock that weregranted were valued at the IPO stated price of $17.00 per share and vested over a three-year period. There was no stock-based compensation expense during2016 and 2015, as all common stock granted under the Plan was fully vested as of December 31, 2014 with no unrecognized compensation expenseremaining. Stock-based compensation expense of $4.8 million was recorded during the year ended December 31, 2014.Long Term Incentive PlanThe Company’s 2011 Long Term Incentive Plan, as amended and restated (the “LTIP”), has different forms of equity issuances allowed under it asfurther described in this section. The Company anticipates that all outstanding LTIP awards that have not vested by the time of the Company's emergencefrom bankruptcy will be canceled pursuant to the terms of the Plan of Reorganization.Restricted Stock under the Long Term Incentive Plan The Company grants shares of restricted stock to directors, eligible employees and officers under its LTIP. Each share of restricted stock representsone share of the Company’s common stock to be released from restriction upon completion of the97 Table of Contentsvesting period. The awards typically vest in one-third increments over three years. Each share of restricted stock is entitled to a non-forfeitable dividend, ifthe Company were to declare one, and has the same voting rights as a share of the Company’s common stock. Shares of restricted stock are valued at theclosing price of the Company’s common stock on the grant date and are recognized as general and administrative expense over the vesting period of theaward. The Company granted no shares of restricted stock under the LTIP during 2016. The Company granted 568,832 and 297,030 shares of restrictedstock under the LTIP to certain employees during 2015 and 2014, respectively. The fair value of the restricted stock granted in 2015 and 2014 was $13.8million and $13.9 million, respectively. The Company recognized compensation expense of $6.1 million, $11.1 million and $13.9 million for the yearsended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016 unrecognized compensation cost was $3.8 million and will be amortizedthrough 2017.In 2016, 2015 and 2014, the Company issued 113,044, 32,450 and 12,919 shares, respectively, of restricted common stock under the LTIP to itsnon-employee directors. The Company recognized compensation expense of $0.7 million for the years ended December 31, 2016, 2015 and 2014,respectively. These awards vest approximately one year after issuance.A summary of the status and activity of non-vested restricted stock is presented below: For the Years Ended December 31, 2016 2015 2014 RestrictedStock Weighted-AverageGrant-DateFair Value RestrictedStock Weighted-AverageGrant-DateFair Value RestrictedStock Weighted-AverageGrant-DateFair Value Non-vested at beginning of year731,818 $29.47 589,529 $37.66 836,002 $25.11Granted113,044 $0.98 601,282 $24.04 309,949 $45.87Vested(355,498) $31.68 (335,419) $32.09 (524,818) $25.95Forfeited(120,477) $27.34 (123,574) $34.86 (31,604) $32.73Non-vested at end of year368,887 $19.45 731,818 $29.47 589,529 $37.66Cash flows resulting from excess tax benefits are to be classified as part of cash flows from financing activities. Excess tax benefits are realized taxbenefits from tax deductions for vested restricted stock in excess of the deferred tax asset attributable to stock compensation costs for such restricted stock.The Company recorded no excess tax benefits for the years ended December 31, 2016, 2015 and 2014.Performance Stock Units under the Long Term Incentive PlanThe Company grants performance stock units (“PSUs”) to certain officers under its LTIP. The number of shares of the Company’s common stock thatmay be issued to settle PSUs ranges from zero to two times the number of PSUs awarded. PSUs are determined at the end of each annual measurement periodover the course of the three-year performance cycle in an amount up to two-thirds of the target number of PSUs that are eligible for vesting (such that anamount equal to 200% of the target number of PSUs may be earned during the performance cycle) although no stock is actually awarded to the participantuntil the end of the entire three-year performance cycle. Any PSUs that have not vested at the end of the applicable measurement period are forfeited. Theperformance criterion for the PSUs is based on a comparison of the Company’s total shareholder return (“TSR”) for the measurement period compared withthe TSRs of a group of peer companies for the same measurement period. Compensation expense associated with PSUs is recognized as general andadministrative expense over the measurement period. The TSR for the Company and each of the peer companies is determined by dividing (A)(i) the averageshare price for the last 30 trading days of the applicable measuring period, minus (ii) the average share price for the 30 trading days immediately precedingthe beginning of the applicable measuring period, by (B) the average share price for the 30 trading days immediately preceding the beginning of theapplicable measuring period. The number of earned shares of the Company's common stock will be calculated based on which quartile its TSR percentageranks as of the end of the annual measurement period relative to the other companies in the comparator group. 98 Table of ContentsThe fair value of the PSUs was measured at the grant date with a stochastic process method using a Monte Carlo simulation. A stochastic process is amathematically defined equation that can create a series of outcomes over time. These outcomes are not deterministic in nature, which means that by iteratingthe equations multiple times, different results will be obtained for those iterations. In the case of the Company’s PSUs, the Company cannot predict withcertainty the path its stock price or the stock prices of its peers will take over the performance period. By using a stochastic simulation, the Company cancreate multiple prospective stock pathways, statistically analyze these simulations, and ultimately make inferences regarding the most likely path the stockprice will take. As such, because future stock prices are stochastic, or probabilistic with some direction in nature, the stochastic method, specifically theMonte Carlo Model, is deemed an appropriate method by which to determine the fair value of the PSUs. Significant assumptions used in this simulationinclude the Company’s expected volatility, risk-free interest rate based on U.S. Treasury yield curve rates with maturities consistent with the measurementperiod, as well as the volatilities for each of the Company’s peers.The following table presents the assumptions used to determine the fair value of the PSUs granted during the years ended December 31, 2015 and2014. For the Years Ended 2015 2014Expected term of award 3 3Risk-free interest rate 0.15% - 0.99% 0.12% - 0.9%Expected volatility 65% 40% - 45% The Company granted no PSUs under the LTIP during 2016. During 2015 and 2014, the Company granted 144,363 and 82,312 PSUs, respectively,under the LTIP to certain officers. The fair value of the PSUs granted in 2015 and 2014 was $4.8 million and $3.5 million, respectively. The Companyrecognized compensation expense of $1.8 million, $2.8 million and $1.3 million for the years ended December 31, 2016, 2015 and 2014, respectively. As ofDecember 31, 2016, unrecognized compensation expense for PSUs was $1.3 million and will be amortized through 2018.

The final number of shares of the Company’scommon stock issued may vary depending on the performance multiplier, which ranges from zero to two, depending on the level of satisfaction of theperformance condition.During the year ended December 31, 2016, the third tranche of the 2014 awards and the second tranche of the 2015 awards both had a zero-timesmultiplier, in accordance with the terms of the respective PSU awards. During the year ended December 31, 2015, the first tranche of the 2015 awards, thesecond tranche of the 2014 awards and the 2013 awards had a zero-times multiplier, 1.00-times multiplier and 0.91-times multiplier, respectively, inaccordance with the terms of the respective PSU awards. During the year ended December 31, 2014, the first tranche of the 2014 awards had a 1.33-timesmultiplier, in accordance with the terms of the respective PSU awards. The earned shares are settled and released at the end of the three-year performancecycle.Long Term Incentive Plan UnitsDuring the year end December 31, 2016, the Company granted 2,958,558 of LTIP units (“units”) for a total fair value $2.9 million, that will settle inshares of the Company's common stock upon vesting. The units vest in one-third increments99 Table of Contentsover three years. The units contain a share price cap of $26 that incrementally decreases the number of shares of the Company's common stock that will bereleased upon vesting if the Company's common stock were to exceed the share price cap.Total expense recorded for the units for the year ended December 31, 2016 was $871,000. As of December 31, 2016, there was $1.5 million of totalunrecognized compensation expense related to unvested units to be amortized through 2019.A summary of the status and activity of non-vested units for the year ended December 31, 2016 is presented below.

The Company matches each employee’scontribution up to six percent of the employee’s base salary. The Company’s matching contributions to the 401(k) Plan were $2.0 million, $1.9 million and$1.4 million for the years ended December 31, 2016, 2015 and 2014, respectively.NOTE 10 - INCOME TAXES Deferred tax assets and liabilities are measured by applying the provisions of enacted tax laws to determine the amount of taxes payable orrefundable currently or in future years related to cumulative temporary differences between the tax bases of assets and liabilities and amounts reported in theCompany’s balance sheet. The tax effect of the net change in the cumulative temporary differences during each period in the deferred tax assets and liabilitiesdetermines the periodic provision for deferred taxes.

The federal net operating loss carryforward begins toexpire in 2031. The benefit of these excess tax deductions will not be recognized for financial statement purposes until the related deductions reduce taxespayable.Federal income tax expense differs from the amount that would be provided by applying the statutory United States federal income tax rate toincome before income taxes primarily due to the effect of state income taxes, rate changes, and other permanent differences, as follows: For the Years Ended December 31, 2016 2015 2014 (in thousands)Federal statutory tax expense (benefit) $(69,633) $(318,654) $11,696Increase (decrease) in tax resulting from: State tax expense net of federal benefit (6,358) (30,178) 1,106Rate change and other 317 3,390 333Valuation allowance 75,674 180,548 —Total income tax expense (benefit) $— $(164,894) $13,135101 Table of ContentsReconciliation of the Company’s effective tax rate to the expected federal tax rate of 35% in 2016, 2015, and 2014 is as follows: For the Years Ended December 31, 2016 2015 2014Expected federal tax rate 35.00 % 35.00 % 35.00%State income taxes 3.2 % 3.31 % 3.29%Change in tax rate (0.16)% (0.37)% 1.01%Valuation allowance (38.04)% (19.83)% —%Effective tax rate — % 18.11 % 39.30%During the year ended December 31, 2016, the decrease in tax rate was primarily due to placing a valuation allowance against net deferred tax assets.There was no deferred income tax benefit or expense in the accompanying statements of operations. The valuation allowance increased to $256.2 million in2016 due to continued deterioration of our operational results. Net operating losses are inherently subject to changes in ownership.During the year ended December 31, 2015, the decrease in tax rate was primarily due to placing a valuation allowance against net deferred tax assets.Total deferred income tax benefit in the accompanying statements of operations $165.7 million. The valuation allowance increased to $181.7 million in2015.During the year ended December 31, 2014, the increase in tax rate was primarily due to an increase in permanent differences. Total deferred incometax expense in the accompanying statements of operations is $13.0 million.The Company had no unrecognized tax benefits as of December 31, 2016, 2015 and 2014. NOTE 11 - ASSET RETIREMENT OBLIGATIONSThe Company recognizes an estimated liability for future costs to abandon its oil and gas properties. The fair value of the asset retirement obligationis recorded as a liability when incurred, which is typically at the time the asset is acquired or placed in service. There is a corresponding increase to thecarrying value of the asset which is included in the proved properties line item in the accompanying balance sheets. The Company depletes the amountadded to proved properties and recognizes expense in connection with accretion of the discounted liability over the remaining estimated economic lives ofthe properties.The Company’s estimated asset retirement obligation liability is based on historical experience in abandoning wells, estimated economic lives,estimated costs to abandon the wells and regulatory requirements. The liability is discounted using the credit-adjusted risk-free rate estimated at the time theliability is incurred and ranges from 8% to 18%. A reconciliation of the Company’s asset retirement obligation is as follows: As of December 31, 2016 2015 (in thousands)Beginning of year $25,688 $21,626Additional liabilities incurred 90 560Accretion expense 2,601 1,944Liabilities settled (691) (469)Revisions to estimate 3,145 2,027End of year $30,833 $25,688Revisions to the liability could occur due to changes in the estimated economic lives, abandonment costs of the wells, inflation rates, credit-adjusted risk-free rates, along with newly enacted regulatory requirements. In 2016, accretion expense increased over 2015 primarily due to the increase inthe credit-adjusted risk-free rate that was in place for the majority of the year. Revisions to estimates for the year ended December 31, 2016 were a result ofdecreased estimated economic well lives coupled with a decrease in the credit-adjusted risk-free rate applied at year-end and an increase in the inflation rateon wells102 Table of Contentsthat had an asset retirement obligation as of the beginning of the year. For the year ended December 31, 2015, the Company has accrued approximately 162,000 of asset retirement obligations in accounts payable andaccrued expenses on the accompanying balance sheets. The Company has accrued $10.6 million of asset retirement obligations in the asset retirementobligations for assets held for sale on the accompanying balance sheets for the year ended December 31, 2015. For additional discussion, please refer toNote 6 - Accounts Payable and Accrued Expenses.NOTE 12 - FAIR VALUE MEASUREMENTS The Company follows fair value measurement authoritative guidance, which defines fair value, establishes a framework for using fair value tomeasure assets and liabilities, and expands disclosures about fair value measurements. The authoritative accounting guidance defines fair value as the pricethat would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Thestatement establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservableinputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing theasset or liability developed based on market data obtained from sources independent of the Company. Unobservable inputs are inputs that reflect theCompany’s assumptions of what market participants would use in pricing the asset or liability developed based on the best information available in thecircumstances. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: Level 1: Quoted prices are available in active markets for identical assets or liabilities Level 2: Quoted prices in active markets for similar assets and liabilities, quoted prices for identical or similar instruments in markets thatare not active, and model-derived valuations whose inputs are observable or whose significant value drivers are observableLevel 3: Significant inputs to the valuation model are unobservable Financial and non-financial assets and liabilities are to be classified based on the lowest level of input that is significant to the fair valuemeasurement. The Company’s assessment of the significance of a particular input to the fair value measurement requires judgment and may affect thevaluation of the fair value of assets and liabilities and their placement within the fair value hierarchy levels. The following tables present the Company’s financial and non-financial assets and liabilities that were accounted for at fair value as of December 31,2016 and 2015 and their classification within the fair value hierarchy: As of December 31, 2016 Level 1 Level 2 Level 3 (in thousands)Unproved properties(2)$— $— $162,682Asset retirement obligations(3)$— $— $3,145 As of December 31, 2015 Level 1 Level 2 Level 3 (in thousands)Derivative assets(1)$— $29,566 $—Unproved properties(2)$— $— $185,530Proved properties(2)$— $— $811,913Asset retirement obligations(3)$— $— $2,027_______________________________(1)This represents a financial asset or liability that is measured at fair value on a recurring basis.(2)This represents non-financial assets that are measured at fair value on a nonrecurring basis due to impairments.

Derivatives Fair value of all derivative instruments are estimated with industry-standard models that consider various assumptions, including quoted forwardprices for commodities, time value of money, volatility factors and current market and contractual prices for the underlying instruments, as well as otherrelevant economic measures. All valuations were compared against counterparty statements to verify the reasonableness of the estimate. The Company’scommodity swaps and collars were validated by observable transactions for the same or similar commodity options using the NYMEX futures index, and weredesignated as Level 2 within the valuation hierarchy.Proved Oil and Gas PropertiesProved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that the carrying costs exceedthe sum of the undiscounted cash flows. Depending on the availability of data, the Company uses Level 3 inputs and either the income valuation technique,which converts future amounts to a single present value amount, to measure the fair value of proved properties through an application of risk-adjusteddiscount rates and price forecasts selected by the Company’s management, or the market valuation approach. The calculation of the risk-adjusted discountrate is a significant management estimate based on the best information available. Management believes that the risk-adjusted discount rate is representativeof current market conditions and reflects the following factors: estimates of future cash payments, expectations of possible variations in the amount and/ortiming of cash flows, the risk premium and nonperformance risk. The price forecast is based on the Company's internal budgeting model derived from theNYMEX strip pricing, adjusted for management estimates and basis differentials. Future operating costs are also adjusted as deemed appropriate for theseestimates. Proved properties classified as held for sale are valued using a market approach, based on an estimated selling price, as evidenced by the mostcurrent bid prices received from third parties. If a relevant estimated selling price is not available, the Company utilizes the income valuation techniquediscussed above. The Company impaired its oil and gas properties in the Mid-Continent region which had a carrying value of $110.0 million to its fair valueof $100.0 million and recognized an impairment of $10.0 million for the year ended December 31, 2016. The Company impaired the Dorcheat MacedoniaField which had a carrying value of $431.2 million to its fair value of $110.0 million and recognized an impairment of $321.2 million for the year endedDecember 31, 2015. The Company impaired the Rocky Mountain region which had a carrying value of $1.1 billion to its fair value of $701.9 million andrecognized an impairment of $419.3 million for the year ended December 31, 2015. For additional discussion on impairments, please refer to Note 4 -Impairments. Unproved Oil and Gas Properties Unproved oil and gas property costs are evaluated for impairment and reduced to fair value when there is an indication that the carrying costs maynot be fully recoverable. To measure the fair value of unproved properties, the Company uses Level 3 inputs and the income valuation technique, whichtakes into account the following significant assumptions: future development plans, risk weighted potential resource recovery, remaining lease life andestimated reserve values. Unproved properties classified as held for sale are valued using a market approach, based on an estimated selling price, as evidencedby the most current bid prices received from third parties. If a relevant estimated selling price is not available, the Company uses the price received for similaracreage in recent transactions by the Company or other market participants in the principal market. The Company impaired non-core acreage in theWattenberg Field due to lease expirations, which had a carrying value of $187.4 million to its fair value of $162.7 million and recognized an impairment ofunproved properties for the year ended December 31, 2016 of 24.7 million. The Company impaired non-core acreage in the Wattenberg Field due to leaseexpirations, which had a carrying value of $210.3 million to its fair value of $185.5 million and recognized an impairment of unproved properties for the yearended December 31, 2015 of $24.8 million.The Company also fully impaired the North Park Basin in June 2015, due to a change in the Company’sdevelopment plan, recognizing an impairment of unproved properties of $8.7 million. Asset Retirement Obligation 104 Table of ContentsThe Company utilizes the income valuation technique to determine the fair value of the asset retirement obligation liability at the point of inceptionby applying a credit-adjusted risk-free rate, which takes into account the Company’s credit risk, the time value of money, and the current economic state, tothe undiscounted expected abandonment cash flows. Upon completion of wells and natural gas plants, the Company records an asset retirement obligation atfair value using Level 3 assumptions. Given the unobservable nature of the inputs, the initial measurement of the asset retirement obligation liability isdeemed to use Level 3 inputs. The Company had 3.1 million and 2.0 million of asset retirement obligations recorded at fair value as of December 31, 2016and 2015, respectively. Long-term Debt As of December 31, 2016, the Company had $500.0 million of outstanding 6.75% Senior Notes and $300.0 million of outstanding 5.75% SeniorNotes, all of which are unsecured senior obligations. The 6.75% Senior Notes are recorded at cost, plus the unamortized premium and net of deferredfinancing costs, on the accompanying balance sheets at $498.4 million and $498.1 million as of December 31, 2016 and 2015, respectively. The fair value ofthe 6.75% Senior Notes as of December 31, 2016 and 2015 was $371.9 million and $301.3 million, respectively. The 5.75% Senior Notes are recorded at cost,net of deferred financing costs, on the accompanying balance sheets at $295.3 million and $294.5 million as of December 31, 2016 and 2015. The fair valueof the 5.75% Senior Notes as of December 31, 2016 and 2015 was $222.0 million and $163.1 million, respectively. The Senior Notes are measured usingLevel 1 inputs based on a secondary market trading price. The Company’s revolving credit facility approximates fair value as the applicable interest rates arefloating. The outstanding balance under the revolving credit facility as of December 31, 2016 and 2015 was $191.7 million and $79.0 million, respectively. NOTE 13 - DERIVATIVES The Company enters into commodity derivative contracts to mitigate a portion of its exposure to potentially adverse market changes in commodityprices and the associated impact on cash flows. All contracts are entered into for other-than-trading purposes. The Company’s derivatives include swaps andcollar arrangements for oil and none of the derivative instruments qualify as having hedging relationships.In a typical commodity swap agreement, if the agreed upon published third-party index price is lower than the swap fixed price, the Companyreceives the difference between the index price and the agreed upon swap fixed price. If the index price is higher than the swap fixed price, the Company paysthe difference.Derivative Assets and Liabilities Fair Value The Company’s commodity derivatives are measured at fair value and are included in the accompanying balance sheets as derivative assets andliabilities. As of December 31, 2016, and as of the filing date of this report, the Company did not have any commodity derivative contracts in place. The following table contain a summary of all the Company’s derivative positions reported on the accompanying balance sheets as of December 31,2015: As of December 31, 2015 Balance Sheet Location Fair Value (in thousands)Derivative Assets: Commodity contractsCurrent assets $29,566Commodity contractsNoncurrent assets —Derivative Liabilities: Commodity contractsCurrent liabilities —Commodity contractsLong-term liabilities —Total derivative asset $29,566The following table summarizes the components of the derivative gain (loss) presented on the accompanying statements of operations:105 Table of Contents For the Years Ended December 31, 2016 2015 2014 (in thousands)Derivative cash settlement gain (loss): Oil contracts(1) $18,333 $128,258 $11,523Gas contracts — 2,738 715Total derivative cash settlement gain (loss)(2) $18,333 $130,996 $12,238 Change in fair value gain (loss) $(29,567) $(74,438) $109,377 Total derivative gain (loss)(2) $(11,234) $56,558 $121,615___________________________(1)During the year ended December 31, 2015, the Company paid $10.5 million to convert its three-way collars, that settled during the third and fourthquarters of 2015, to two-way collars.(2)Total derivative gain (loss) and the derivative cash settlement gain for the years ended December 31, 2016, 2015 and 2014 is reported in the derivative(gain) loss and derivative cash settlements line items on the accompanying statements of cash flows within the net cash provided by operating activities. NOTE 14 - EARNINGS PER SHARE The Company issues shares of restricted stock entitling the holders to receive non-forfeitable dividends, if and when, the Company was to declare adividend, before vesting, thus making the awards participating securities. The awards are included in the calculation of earnings per share under the two-classmethod. The two-class method allocates earnings for the period between common shareholders and unvested participating shareholders and losses tocommon shareholders only.The Company issues units, which represent the right to receive, upon vesting, shares of the Company's common stock on a one to one basis up to ashare price of $26. In the event the price of the Company's common stock were to exceed $26, the number of shares distributed would be adjusted downwardso that the shares distributed would represent a value equivalent to $26 per share. The Company issues PSUs, which represent the right to receive, upon settlement of the PSUs, a number of shares of the Company’s common stockthat range from zero to two times the number of PSUs granted on the award date. The number of potentially dilutive shares related to PSUs is based on thenumber of shares, if any, that would be issuable at the end of the respective reporting period, assuming that date was the end of the measurement periodapplicable to such PSUs. Please refer to Note 9 - Stock-Based Compensation for additional discussion.106 Table of ContentsThe following table sets forth the calculation of income (loss) per basic and diluted shares from continuing and discontinued operations and netincome (loss) for the years ended December 31, 2016, 2015 and 2014: For the Years Ended December 31, 2016 2015 2014 (in thousands, except per share amounts)Income (loss) from continuing operations: Income (loss) from continuing operations $(198,950) $(745,547) $16,982Less: undistributed income to unvested restricted stock — — 315Undistributed income (loss) to common shareholders (198,950) (745,547) 16,667Basic income (loss) per common share from continuing operations $(4.04) $(15.57) $0.42Diluted income (loss) per common share from continuing operations $(4.04) $(15.57) $0.41 Income from discontinued operations: Income from discontinued operations $— $— $3,301Less: undistributed income to unvested restricted stock — — 62Undistributed income to common shareholders — — 3,239Basic income per common share from discontinued operations $— $— $0.08Diluted income per common share from discontinued operations $— $— $0.08 Net income (loss): Net income (loss) $(198,950) $(745,547) $20,283Less: undistributed income to unvested restricted stock — — 377Undistributed income (loss) to common shareholders (198,950) (745,547) 19,906Basic net income (loss) per common share $(4.04) $(15.57) $0.50Diluted net income (loss) per common share $(4.04) $(15.57) $0.49 Weighted-average shares outstanding - basic 49,268 47,874 40,139Add: dilutive effect of contingent PSUs — — 151Weighted-average shares outstanding - diluted 49,268 47,874 40,290The Company was in a net loss position for the years ended December 31, 2016 and 2015, which made the 519,362 and 277,634 potentially dilutiveshares, anti-dilutive. The Company had no anti-dilutive shares for the year ended and 2014. The participating shareholders are not contractually obligated toshare in the losses of the Company, and therefore, the entire net loss is allocated to the outstanding common shareholders.NOTE 15 - CAPITAL STOCK On February 6, 2015, the Company completed a public offering of 8,050,000 shares of its common stock generating net proceeds of $202.7 millionafter deducting underwriter discounts, commissions and offering expenses of approximately $6.6 million. The Company used a portion of the net proceeds torepay all of the then outstanding borrowings under its revolving credit facility and for general corporate purposes, including its drilling and developmentprogram and other capital expenditures.NOTE 16 - OIL AND GAS ACTIVITIESThe Company’s oil and natural gas activities are entirely within the United States. Costs incurred in oil and natural gas producing activities are asfollows:107 Table of Contents For the Years Ended December 31, 2016 2015 2014 (in thousands)Acquisition(1) $97 $16,270 $228,616Development(2)(3) 31,209 393,187 659,633Exploration 74 6,284 5,345Total(4) $31,380 $415,741 $893,594_________________________(1)Acquisition costs for unproved properties for the years ended December 31, 2016, 2015 and 2014 were $97,000, $15.3 million and $202.7 million,respectively. There were no acquisition costs for proved properties for the year ended December 31, 2016 and $1.0 million and $25.9 million, for theyears ended December 31, 2015 and 2014, respectively.(2)Development costs include workover costs of $6.0 million, $10.0 million and $9.8 million charged to lease operating expense during the years endedDecember 31, 2016, 2015 and 2014, respectively.(3)Includes amounts relating to asset retirement obligations of $3.1 million, $2.4 million and $6.3 million for the years ended December 31, 2016, 2015 and2014, respectively.Suspended Well CostsThe Company did not incur any exploratory wells costs during the year ended December 31, 2016. During the year ended December 31, 2015, theCompany incurred $9.5 million of drilling costs for three exploratory wells, one of which was located in the North Park Basin and the other two were outsideof the Company's current development area in southern Arkansas and deemed them all dry holes by the end of 2015. During the year ended December 31,2014, the Company incurred drilling costs for one exploratory well of $1.0 million and deemed it a dry hole by the end of 2014.NOTE 17 - DISCLOSURES ABOUT OIL AND GAS PRODUCING ACTIVITIES (UNAUDITED)The proved reserve estimates at December 31, 2016, 2015 and 2014 are internally generated with an audit performed by NSAI, our third partyindependent reserve engineers. The estimates of proved reserves are inherently imprecise and are continually subject to revision based on production history,results of additional exploration and development, price changes and other factors.108 Table of ContentsAll of BCEI’s oil, natural gas liquids, and natural gas reserves are attributable to properties within the United States. A summary of BCEI’s changesin quantities of proved oil, natural gas liquids, and natural gas reserves for the years ended December 31, 2016, 2015 and 2014 are as follows: Natural Natural Oil Gas Gas Liquids (MBbl)(1) (MMcf) (MBbl)(1)Balance-December 31, 2013 46.482 139.614 —Extensions and discoveries(2) 13.222 41.963 —Production (6.018) (14.114) —Sales of minerals in place (0.043) (0.073) —Purchases of minerals in place 0.709 1.214 —Revisions to previous estimates(3) 3.76 19.947 —Balance-December 31, 2014 58.112 188.551 —Three stream conversion adjustment (3.352) — 3.352Extensions and discoveries(2) 6.936 15.849 2.43Production (6.072) (14.11) (1.676)Purchases of minerals in place 0.719 3.521 0.234Revisions to previous estimates(3) 1.05 (49.584) 15.578Balance-December 31, 2015 57.393 144.227 19.918Extensions, discoveries and infills(2) 6.133 15.128 2.142Production (4.31) (11.907) (1.491)Sales of minerals in place (0.1) (0.343) (0.035)Revisions to previous estimates(3) (9.02) (9.06) (2.987)Balance-December 31, 2016 50.096 138.045 17.547Proved developed reserves: December 31, 2014 30.542 94.494 —December 31, 2015 28.892 77.48 10.359December 31, 2016 26.313 85.972 9.951Proved undeveloped reserves: December 31, 2014 27.57 94.057 —December 31, 2015 28.501 66.747 9.559December 31, 2016 23.783 52.073 7.596________________________(1)Natural gas liquid reserves were classified with oil reserves through December 31, 2014. Natural gas liquids are separately accounted for effective as ofJanuary 1, 2015, resulting in three-stream presentation. Effective January 1, 2015 the Company revised the agreements with its natural gas processors inthe Rocky Mountain region to sell and report operated sales volumes on a three stream basis, which allows for separate reporting of NGLs extracted fromthe natural gas stream and sold as a separate product. The contract revisions necessitated a change in the Company's reporting of estimated reservevolumes. Prior period estimated reserve volumes have not been reclassified to conform to the current presentation given the prospective nature of theagreements.(2)At December 31, 2016, horizontal development in the Wattenberg Field resulted in additions of 1,632 MBoe and infill down-spacing within theWattenberg Field resulted in 9,164 MBoe to the additions, extensions and infills category.At December 31, 2015, horizontal development in the Wattenberg Field resulted in additions in extensions and discoveries of 11,708 MBoe, which is97% of our total additions of 12,008 MBoe. The remainder of the additions were the result of vertical drilling during the year in the Dorcheat MacedoniaField, Mid-Continent region.109 Table of ContentsAt December 31, 2014, horizontal development in the Wattenberg Field, Rocky Mountain region, resulted in additions in extensions and discoveries of18,980 MBoe, which is 94% of our total additions of 20,216 MBoe. The remainder of the additions came from our Dorcheat Madedonia Field, Mid-Continent region.(3)As of December 31, 2016, the Company revised its proved reserves downward by 13,517 MBoe. The commodity prices at December 31, 2016 decreasedto $42.75 per Bbl WTI and $2.48 per MMBtu HH from $50.28 per Bbl WTI and $2.59 per MMBtu HH at December 31, 2015. The negative effects ofcommodity price reductions on reserves were offset by lower cost estimates to drill and complete future development locations in the Wattenberg Fieldalong with lower operating cost estimates across the Company's operations to reflect a positive reserves adjustment (net of price reductions) of 4,652MBoe. Also, all future proved undeveloped locations in the Mid-Continent region were demoted to non-proved reserves resulting in a negative revisionof 7,761 MBoe. In the Wattenberg Field, certain proved undeveloped locations totaling 8,611 MBoe were demoted due to them not being centric tocurrent infrastructure. The Company also had negative other engineering revisions of 1,797 MBoe in 2016.As of December 31, 2015, the Company revised its proved reserves upward by 8,364 Mboe. The Company was successful in offsetting the negativepricing revision of 28,810 Mboe that resulted from a decrease in commodity price from $94.99 per Bbl WTI and $4.35 per MMBtu HH for the year endedDecember 31, 2014 to $50.28 per Bbl WTI and $2.59 per MMBtu HH for the year ended December 31, 2015, by reducing the costs to drill and completewells in both the Rocky Mountain and Mid-Continent regions and improving reserves by increasing productivity of proved developed producing wellsin the Wattenberg Field horizontal program. Total positive engineering revisions as of December 31, 2015, were 37,174 MBoe, of which 30,086 MBoe(81%) related to reserve changes in the Wattenberg Field. In the Wattenberg Field, the majority of the positive revisions resulted from a combination ofdecreased drilling and completion costs of 29% ($3.0 million per standard reach lateral well as of December 31, 2015 compared to $4.2 million as ofDecember 31, 2014) and an increase in productivity from horizontal proved developed producing wells which increased the offsetting provedundeveloped reserves. The increase in proved developed producing reserves is primarily attributed to the installation of infrastructure in the east side ofthe Wattenberg Field. Another significant contribution to the positive reserve revision in the Wattenberg Field is a contract change as of January 1, 2015which gives the Company ownership of the natural gas liquids from the Company's gas production. This conversion from two stream (wet gas and oil) tothree stream (dry gas, natural gas liquids and oil) added 8,560 MBoe to the Company's proved reserves as of December 31, 2015.As of December 31, 2014, we revised our proved reserves upward by 7,333 Mboe, excluding pricing revisions, due primarily to the addition of 49 newproved undeveloped locations on 80-acre spacing, directly offsetting economic proved producing wells drilled prior to 2014, 21 diagonal offsets toeconomic proved producing wells and 12 proved undeveloped locations greater than one offset to economic proved producing wells but withindeveloped areas and surrounded by proved producing wells. As of December 31, 2014, approximately 70% of our horizontal development in theWattenberg Field was in the Niobrara B formation. A total of 119 horizontal proved undeveloped locations were added to the proved reserves atDecember 31, 2014 to either extensions and discoveries or revisions to previous estimates. The positive engineering revision was offset by a smallnegative performance revision of approximately 540 MBoe. A small negative pricing revision of 248 MBoe resulted from a decrease in averagecommodity price from $96.91 per Bbl WTI and $3.67 per MMBtu HH for the year ended December 31, 2013 to $94.99 per Bbl WTI and $4.35 perMMBtu HH for the year ended December 31, 2014. The standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves were prepared in accordance withaccounting authoritative guidance. Future cash inflows were computed by applying prices to estimated future production. Future production anddevelopment costs are computed by estimating the expenditures to be incurred in developing and producing the proved oil and natural gas reserves at year-end, based on costs and assuming continuation of existing economic conditions.Future income tax expenses are calculated by applying appropriate year-end tax rates to future pretax net cash flows relating to proved oil andnatural gas reserves. Future income tax expenses give effect to permanent differences, tax credits and loss carryforwards relating to the proved oil and naturalgas reserves. Future net cash flows are discounted at a rate of 10% annually to derive the standardized measure of discounted future net cash flows. Thiscalculation procedure does not necessarily result in an estimate of the fair market value or the present value of the Company's oil and natural gas properties.110 Table of ContentsThe standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves are as follows: For the Years Ended December 31, 2016 2015 2014 (in thousands)Future cash flows $2,424,415 $3,122,574 $5,780,745Future production costs (1,365,765) (1,706,607) (2,257,572)Future development costs (468,804) (697,045) (952,041)Future income tax expense — — (457,625)Future net cash flows 589,846 718,922 2,113,50710% annual discount for estimated timing of cash flows (312,891) (391,106) (1,006,131)Standardized measure of discounted future net cash flows $276,955 $327,816 $1,107,376Future cash flows as shown above were reported without consideration for the effects of derivative transactions outstanding at period end.The changes in the standardized measure of discounted future net cash flows relating to proved oil and natural gas reserves are as follows: For the Years Ended December 31, 2016 2015 2014 (in thousands)Beginning of period $327,816 $1,107,376 $925,283Sale of oil and gas produced, net of production costs (123,494) (197,643) (435,792)Net changes in prices and production costs (126,536) (1,117,624) (331,930)Extensions, discoveries and improved recoveries 22,800 76,429 492,144Development costs incurred 19,701 84,180 116,958Changes in estimated development cost 281,062 178,003 (15,131)Purchases of minerals in place — (971) 30,919Sales of minerals in place 16 — (1,173)Revisions of previous quantity estimates (182,938) (170,277) 122,169Net change in income taxes — 233,086 68,856Accretion of discount 32,782 134,046 122,722Changes in production rates and other 25,746 1,211 12,351End of period $276,955 $327,816 $1,107,376The average wellhead prices used in determining future net revenues related to the standardized measure calculation as of December 31, 2016, 2015and 2014 were calculated using the twelve-month arithmetic average of first-day-of-the-month price inclusive of adjustments for quality and location.

The Bankruptcy Court has granted the Debtors'motion seeking to administer all of the Debtors' Chapter 11 Cases jointly under the caption In re Bonanza Creek Energy, Inc., et al (Case No. 17-10015). TheDebtors will continue to operate their businesses as “debtors in possession” under the jurisdiction of the Bankruptcy Court and in accordance with theapplicable provisions of the Bankruptcy Code and orders of the Bankruptcy Court. The Bankruptcy Court has granted all of the first day motions filed by theDebtors that were designed primarily to minimize the impact of the Chapter 11 proceedings on the Company's operations, customers and employees. As aresult, the Company is not only able to conduct normal business activities and pay all associated obligations for the period following its bankruptcy filing,but it is also authorized to pay and has paid pre-petition employee wages and benefits, pre-petition amounts owed to certain lienholders and vendorsproviding services and supplies to lease operations, pre-petition amounts owed to counterparts that transport or purchase the Company’s production, andfunds belonging to third parties, including royalty holders and joint working interest owners. During the pendency of the Chapter 11 case, all transactionsoutside the ordinary course of our business require the prior approval of the Bankruptcy Court.The subsidiary Debtors in the Chapter 11 Cases are: Bonanza Creek Energy Operating Company, LLC; Bonanza Creek Energy Resources, LLC;Holmes Eastern Company, LLC; Rocky Mountain Infrastructure, LLC; Bonanza Creek Energy Upstream LLC; and Bonanza Creek Energy Midstream, LLC.As of January 4, 2017, the Company had approximately (i) $191.7 million outstanding under its revolving credit facility, (ii) $531.9 million inoutstanding obligations under the 6.75% Senior Notes and (iii) $335.2 million outstanding under the 5.75% Senior Notes. The revolving credit facility andSenior Notes provide that as a result of the commencement of the Chapter 11 Cases, the principal and accrued interest due thereunder shall be immediatelydue and payable. Any efforts to enforce such payment obligations under the Debt Instruments are automatically stayed as a result of the filing of the112 Table of ContentsBankruptcy Petitions, and the creditors’ rights of enforcement in respect of the Debt Instruments are subject to the applicable provisions of the BankruptcyCode and orders of the Bankruptcy Court.A confirmation hearing on the Prepackaged Plan and the associated Disclosure Statement is currently scheduled to begin on April 3, 2017.Automatic Stay Subject to certain specific exceptions under the Bankruptcy Code, the Chapter 11 filings automatically stayed most judicial or administrativeactions against the Company and the Chapter 11 Subsidiaries as well as efforts by creditors to collect on or otherwise exercise rights or remedies with respectto pre-petition claims. As a result, for example, most creditor actions to obtain possession of property from us or any of the Chapter 11 Subsidiaries, or tocreate, perfect or enforce any lien against our property or any of the Chapter 11 Subsidiaries, or to collect on or otherwise exercise rights or remedies withrespect to a pre-petition claim are stayed.Restructuring Support AgreementOn December 23, 2016, Bonanza Creek Energy, Inc. and its subsidiaries entered into a Restructuring Support Agreement (the “RSA”) with (i) holders(collectively, the “Supporting Noteholders”) of approximately 51% in aggregate principal amount of Bonanza’s 5.75% Senior Notes due 2023 and 6.75%Senior Notes due 2021 and (ii) NGL Energy Partners, LP and NGL Crude Logistics, LLC (collectively, and together with the Company and the SupportingNoteholders, the “RSA Parties”).The RSA provides for, among other things, (a) the equitization of the Company’s unsecured obligations pursuant to the Plan, includingapproximately $800 million in principal amount of Senior Notes, (b) a fully backstopped rights offering for the purchase of $200 million of common stock ofreorganized Bonanza Creek Energy, Inc. (“Reorganized Bonanza”), and (c) the entry into a new crude oil purchase agreement between the Company andNGL Crude Logistics, LLC (collectively the “Restructuring Transactions”).The RSA contains certain covenants on the part of each of the RSA Parties, including limitations on the Company’s ability to pursue transactionsother than the Restructuring, commitments by the Supporting Noteholders and NGL to vote in favor of the Plan, commitments by the RSA Parties tonegotiate in good faith to finalize the documents and agreements governing the Restructuring and otherwise facilitate the Restructuring Transactions. TheRSA also provides for customary conditions to the obligations of the parties and for termination by mutual agreement or upon the occurrence of certainevents, including without limitation, the failure to achieve certain milestones.Plan of ReorganizationThe Plan, which is subject to approval of the Bankruptcy Court, contemplates that, among other things, on the effective date of the Plan (the“Effective Date”):•The Senior Notes and existing common shares of Bonanza (“Existing Common Shares”) will be canceled, and Reorganized Bonanza will issue (i)new common shares (the “New Common Shares”), (ii) three (3) year warrants (the “Warrants”) entitling their holders upon exercise thereof, on a prorata basis, to 7.5% of the total outstanding New Common Shares at a per share price based upon a total equity value of $1,450,000,000 of theReorganized Bonanza, and (iii) rights (the “Subscription Rights”) to acquire the New Common Shares offered in connection with the Rights Offering(“Rights Offering Equity”), each of which will be distributed as set forth below;•Holders of allowed claims (“RBL Claims”) on account of debt arising under the revolving credit facility shall be entitled to receive, in full and finalsatisfaction of its allowed RBL Claim;•Holders of allowed general unsecured claims against Bonanza shall be entitled to receive their ratable share of: (a) 29.4% of the New CommonShares, subject to dilution by the Rights Offering Equity, the Management Incentive Plan (as defined in the Plan) and the Warrants and (b) 37.8% ofthe Subscription Rights;•Holders of allowed general unsecured claims against Bonanza Creek Operating, shall receive their ratable share of 17.6% of the New CommonShares subject to dilution by the Rights Offering Equity, the Management Incentive Plan and the Warrants.113 Table of Contents•Holders of allowed general unsecured claims against Debtors other than Bonanza and Bonanza Creek Operating, shall receive their ratable share of:(a) 48.5% of the New Common Shares, subject to dilution by the Rights Offering Equity, the Management Incentive Plan (as defined in the Plan) andthe Warrants and (b) 62.2% of the Subscription Rights;•Holders of Existing Common Shares shall neither receive any distributions nor retain any property on account thereof pursuant to the Plan.Notwithstanding the foregoing, on or as soon as reasonably practicable after the Effective Date, holders of Existing Common Shares shall receive, inexchange for the releases by such holders of the Released Parties (as defined in the Plan), their ratable share of (i) 4.5% of the New Common Shares,subject to dilution by the Rights Offering Equity, the Management Incentive Plan and the Warrants and (ii) the Warrants (the “SettlementConsideration”); provided, however, that any holder of Existing Common Shares that opts not to grant the voluntary releases contained in section11.8 of the Plan shall not be entitled to receive its ratable share of the Settlement Consideration;•Holders of allowed Administrative Expense Claims, Priority Tax Claims, Other Priority Claims, and Unsecured Trade Claims (each as defined in thePlan) shall be entitled to payment in full in cash or other treatment that will render such claim unimpaired under section 1124 of the BankruptcyCode;•Holders of allowed Other Secured Claims (as defined in the Plan) shall be entitled to payment in full in cash; reinstatement of the legal, equitableand contractual rights of the holder of such claim; a distribution of the proceeds of the sale or disposition of the collateral securing such claim, ineach case, solely to the extent of the value of the holder’s secured interest in such collateral; return of collateral securing such claim; or othertreatment that will render such claim unimpaired under section 1124 of the Bankruptcy Code.Executory ContractsSubject to certain exceptions, under the Bankruptcy Code, the Company and the Chapter 11 Subsidiaries may assume, assign, or reject certainexecutory contracts and unexpired leases subject to the approval of the Bankruptcy Court and fulfillment of certain other conditions. The rejection of anexecutory contract or unexpired lease is generally treated as a pre-petition breach of such executory contract or unexpired lease and, subject to certainexceptions, relieves the Company and the Chapter 11 Subsidiaries of performing their future obligations under such executory contract or unexpired leasebut may give rise to a general unsecured claim against us or the applicable Chapter 11 Subsidiaries for damages caused by such rejection. The assumption ofan executory contract or unexpired lease generally requires the Company and the Chapter 11 Subsidiaries to cure existing monetary defaults under suchexecutory contract or unexpired lease and provide adequate assurance of future performance. Any description of the treatment of an executory contract orunexpired lease with the Company or any of the Chapter 11 Subsidiaries, including any description of the obligations under any such executory contract orunexpired lease, is qualified by and subject to any rights we have with respect to executory contracts and unexpired leases under the Bankruptcy Code.On February 3, 2017, the Company and the Chapter 11 Subsidiaries filed motions (the “9019 Motions”) to approve settlements with Silo Energy,LLC and NGL pursuant to Rule 9019 of the Federal Rules of Bankruptcy Procedure and to authorize the termination and release with Silo and the assumptionof certain amended agreements with NGL pursuant to section 365 of the Bankruptcy Code. As set forth in detail in the 9019 Motions, the settlements providefor the material modification of the agreements and certain claims, guarantees, and payments in favor of the Company. The hearing to consider the 9019Motions is scheduled for April 3, 2017. Please refer to Note 8 - Commitments and Contingencies for additional discussion.Chapter 11 Filing Impact on Creditors and ShareholdersUnder the priority requirements established by the Bankruptcy Code, unless creditors agree otherwise, pre-petition liabilities to creditors and post-petitionliabilities must be satisfied in full before the holders of our existing common stock are entitled to receive any distribution or retain any property under a planof reorganization. The ultimate recovery to creditors, if any, will not be determined until confirmation and implementation of the Plan. The outcome of theChapter 11 proceedings remains uncertain at this time and, as a result, we cannot accurately estimate the amounts or value of distributions that creditors mayreceive.Backstop Commitment AgreementOn December 23, 2016, the Company entered into a backstop commitment agreement (the “Backstop Commitment Agreement”) with theSupporting Noteholders party thereto (collectively, the “Backstop Parties”), whereby each Backstop Party agreed to backstop the Rights Offering in a certainspecified amount (collectively, the “Backstop Commitments”).114 Table of ContentsPursuant to the Backstop Commitment Agreement, each of the Backstop Parties, severally and not jointly, agreed to participate in the Rights Offering andpurchase the Rights Offering Shares in accordance with the percentages set forth in the Backstop Commitment Agreement (the “Backstop Party Percentages”)to the extent unsubscribed under the Rights Offering. In exchange for providing the Backstop Commitments, the Company has agreed to pay the BackstopParties, subject to approval by the Bankruptcy Court, a backstop commitment fee in an amount equal to six percent of the aggregate amount of the BackstopCommitments payable in New Common Shares issued at the same price as the Rights Offering Equity, and to reimburse the administrative expenses incurredby the Backstop Parties in connection with the Backstop Commitment Agreement.The Backstop Commitment Agreement will be terminable by the Company and/or the Requisite Commitment Parties (as defined in the BackstopCommitment Agreement) upon certain customary events specified therein, including, among others, (i) the termination of the RSA, (ii) the failure to meetcertain specified milestones, or (iii) (A) the Bankruptcy Court approves or authorizes the Company to enter into an Alternative Transaction (as defined in theBackstop Commitment Agreement) or (B) entry by the Company into any contract providing for the consummation of any Alternative Transaction or filesany motion or application seeking authority to propose, join in or participate in the formation of, any actual or proposed Alternative Transaction. TheCompany may be required to pay a termination fee in the amount of $8,000,000 to non-defaulting Backstop Parties if the Backstop Commitment Agreementis terminated under certain conditions.Restrictions on Trading of Our Equity Securities to Protect Our Use of Net Operating Losses The Bankruptcy Court has issued a final order pursuant to Sections 105(a), 362(a)(3) and 541 of the Bankruptcy Code enabling us and the Chapter 11Subsidiaries to avoid limitations on the use of our income tax net operating loss carryforwards and certain other tax attributes by imposing certain noticeprocedures and transfer restrictions on the trading of our equity securities. In general, the order applies to any person that, directly or indirectly, beneficiallyowns (or would beneficially own as a result of a proposed transfer) at least 5.0 percent of our outstanding common stock (a “Substantial Stockholder”), andrequires that each Substantial Stockholder file with the Bankruptcy Court and serve us with notice of such status. Under the order, prior to any proposedacquisition or disposition of equity securities that would result in an increase or decrease in the amount of our equity securities owned by a SubstantialStockholder, or that would result in a person or entity becoming a Substantial Stockholder, such person or entity is required to file with the Bankruptcy Courtand notify us of such acquisition or disposition. We have the right to seek an injunction from the Bankruptcy Court to prevent certain acquisitions or sales ofour common stock if the acquisition or sale would pose a material risk of adversely affecting our ability to utilize such tax attributes.Risks Associated with Chapter 11 ProceedingsFor the duration of our Chapter 11 proceedings, our operations and our ability to develop and execute our business plan are subject to the risks anduncertainties associated with the Chapter 11 proceedings as described in Item 1A, “Risk Factors.” As a result of these risks and uncertainties, our assets,liabilities, officers and/or directors could be significantly different following the outcome of the Chapter 11 proceedings, and the description of ouroperations, properties and capital plans included in this Annual Report may not accurately reflect our operations, properties and capital plans following theChapter 11 process.Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.None. Item 9A. Controls and Procedures.Evaluation of Disclosure Controls and ProceduresOur management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of ourdisclosure controls and procedures as of December 31, 2016. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e)under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by acompany in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified inSEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required tobe disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management,including its principal executive and principal financial officers and internal audit function, as appropriate to allow timely decisions regarding requireddisclosure. Based on the evaluation of our disclosure controls and procedures as of December 31, 2016, our principal executive officer and principal financialofficer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.115 Table of ContentsManagement recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance ofachieving their objectives and management necessarily applies its judgment in evaluating the cost‑benefit relationship of possible controls and procedures.To assist management, we have established an internal audit function to verify and monitor our internal controls and procedures. The Company’s internalcontrol system is supported by written policies and procedures, contains self-monitoring mechanisms and is audited by the internal audit function.Appropriate actions are taken by management to correct deficiencies as they are identified.Management’s Assessment of Internal Control Over Financial ReportingThe Company’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined inExchange Act Rule 13a-15(f). The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s ChiefExecutive Officer and Principal Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation ofconsolidated financial statements for external purposes in accordance with accounting principles generally accepted in the United States. Because of itsinherent limitations, internal control over financial reporting may not detect or prevent misstatements. Also, projections of any evaluation of theeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or processes may deteriorate.As of December 31, 2016, management assessed the effectiveness of our internal control over financial reporting based on the criteria for effectiveinternal control over financial reporting established in Internal Control-Integrated Framework, issued by the Committee of Sponsoring Organizations of theTreadway Commission in 2013. Based on the assessment, management determined that the Company maintained effective internal control over financialreporting as of December 31, 2016, based on those criteria. Management included in its assessment of internal control over financial reporting allconsolidated entities.Hein & Associates LLP, the independent registered public accounting firm that audited the consolidated financial statements included in thisAnnual Report on Form 10-K, has issued an attestation report on the effectiveness of internal control over financial reporting as of December 31, 2016, whichis included in the consolidated financial statements in Item 8, Part II of this Annual Report on Form 10-K.Changes in Internal Control over Financial ReportingThere were no changes in our internal control over financial reporting identified in management’s evaluation pursuant to Rules 13a-15(d) or 15d-15(d) of the Exchange Act during the year ended December 31, 2016 that materially affected, or are reasonably likely to materially affect, our internal controlover financial reporting.REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRMTo the Board of Directors and StockholdersBonanza Creek Energy Inc.We have audited Bonanza Creek Energy, Inc. and subsidiaries’ internal control over financial reporting as of December 31, 2016, based on criteriaestablished in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.Bonanza Creek Energy, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of theeffectiveness of internal control over financial reporting included in the accompanying Management’s Assessment of on Internal Control Over FinancialReporting. Our responsibility is to express an opinion on the company’s internal control over financial reporting based on our audit. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require thatwe plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all materialrespects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, andtesting and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such otherprocedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reportingand the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal controlover financial reporting includes those policies and procedures that (a) pertain to the maintenance of records that, in reasonable detail, accurately and fairlyreflect the transactions and dispositions of the assets of the company; (b) provide reasonable assurance that transactions are recorded as necessary to permitpreparation of financial116 Table of Contentsstatements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only inaccordance with authorizations of management and directors of the company; and (c) provide reasonable assurance regarding prevention or timely detectionof unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation ofeffectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliancewith the policies or procedures may deteriorate. In our opinion, Bonanza Creek Energy, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2016,based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commissionin 2013. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheetsof Bonanza Creek Energy, Inc. and subsidiaries as of December 31, 2016 and 2015, and the related consolidated statements of operations and comprehensiveincome, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2016, and our report dated March 15, 2017expressed an unqualified opinion. Our report dated March 15, 2017 contains an explanatory paragraph that states there is substantial doubt about theCompany’s ability to continue as a going concern.Hein & Associates LLPDenver, ColoradoMarch 15, 2017Item 9B.

Fenoglio Scott A. Fenoglio Senior Vice President, Finance & Planning January 27, 2017 Exhibit 99.1Mr. Jeff E. WojahnReserves Committee of Bonanza Creek Energy, Inc.c/o Bonanza Creek Energy, Inc.410 Seventeenth Street, Suite 1400Denver, Colorado 80202Dear Mr. Wojahn:In accordance with your request, we have audited the estimates prepared by Bonanza Creek Energy, Inc. (BCEI), as of December 31, 2016, of the provedreserves and future revenue to the BCEI interest in certain oil and gas properties located in Arkansas and Colorado. We have examined the estimates withrespect to reserves quantities, reserves categorization, future producing rates, future net revenue, and the present value of such future net revenue, using thedefinitions set forth in U.S. Securities and Exchange Commission (SEC) Regulation S-X Rule 4‑10(a). The estimates of reserves and future revenue havebeen prepared in accordance with the definitions and regulations of the SEC and, with the exception of the exclusion of future income taxes, conform to theFASB Accounting Standards Codification Topic 932, Extractive Activities—Oil and Gas. We completed our audit on or about the date of this letter. This reporthas been prepared for BCEI's use in filing with the SEC; in our opinion the assumptions, data, methods, and procedures used in the preparation of this reportare appropriate for such purpose.The following table sets forth BCEI's estimates of the net reserves and future net revenue, as of December 31, 2016, for the audited properties: Net Reserves Future Net Revenue (M$) Oil NGL Gas Present WorthCategory (MBBL) (MBBL) (MMCF) Total at 10% Proved Developed Producing 25,321.1 9,775.1 83,636.0 391,601.9 245,215.6Proved Developed Non-Producing 992.5 175.8 2,335.9 19,514.7 11,838.8Proved Undeveloped 23,782.9 7,595.9 52,072.9 178,729.5 19,901.0 Total Proved 50,096.5 17,546.8 138,044.8 589,846.1 276,955.4The oil volumes shown include crude oil and condensate. Oil and natural gas liquids (NGL) volumes are expressed in thousands of barrels (MBBL); a barrelis equivalent to 42 United States gallons. Gas volumes are expressed in millions of cubic feet (MMCF) at standard temperature and pressure bases.When compared on a lease-by-lease basis, some of the estimates of BCEI are greater and some are less than the estimates of Netherland, Sewell &Associates, Inc. (NSAI). However, in our opinion the estimates shown herein of BCEI's reserves and future revenue are reasonable when aggregated at theproved level and have been prepared in accordance with the Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Informationpromulgated by the Society of Petroleum Engineers (SPE Standards). Additionally, these estimates are within the recommended 10 percent tolerance threshold set forth in the SPE Standards. BCEI has included reserves for locations in the proved undeveloped category based on BCEI's reasonableexpectation that it will emerge from bankruptcy with availablefinancing to implement the development plan for these locations. This expectation is supported by the current bankruptcy plan submitted to the court and theanticipated approval of the Restructuring SupportAgreement (RSA) announced on December 23, 2016. This RSA reduces BCEI debt and provides access to additional equity funding to adequately meet therequired capital budget. We are satisfied with the methods and procedures used by BCEI in preparing the December 31, 2016, estimates of reserves andfuture revenue, and we saw nothing of an unusual nature that would cause us to take exception with the estimates, in the aggregate, as prepared by BCEI.The estimates shown herein are for proved reserves. BCEI's estimates do not include probable or possible reserves that may exist for these properties, nor dothey include any value for undeveloped acreage beyond those tracts for which undeveloped reserves have been estimated. BCEI has included estimates ofproved undeveloped reserves for certain locations that generate positive future net revenue but have negative present worth discounted at 10 percent basedon the constant prices and costs discussed in subsequent paragraphs of this letter. These locations have been included based on the operators' intent to drillthese wells, as evidenced by BCEI's internal budget, reserves estimates, and price forecast. Reserves categorization conveys the relative degree of certainty;reserves subcategorization is based on development and production status. The estimates of reserves and future revenue included herein have not beenadjusted for risk.Prices used by BCEI are based on the 12-month unweighted arithmetic average of the first-day-of-the-month price for each month in the period Januarythrough December 2016. For oil and NGL volumes, the average West Texas Intermediate spot price of $42.75 per barrel is adjusted for quality, transportationfees, and market differentials. Transportation fees are inclusive of December 2016 negotiated reductions to firm transportation contracts. No adjustmentshave been made to estimates of future revenue to account for any potential shortfall or deficiency in fulfilling these contracts. For gas volumes, the averageHenry Hub spot price of $2.481 per MMBTU is adjusted for energy content, transportation fees, and market differentials. All prices are held constantthroughout the lives of the properties. The average adjusted product prices weighted by production over the remaining lives of the properties are $38.42 perbarrel of oil, $12.12 per barrel of NGL, and $2.069 per MCF of gas.Operating costs used by BCEI are based on historical operating expense records. For the nonoperated properties, these costs include the per-well overheadexpenses allowed under joint operating agreements along with estimates of costs to be incurred at and below the district and field levels. Operating costs forthe operated properties are limited to direct lease- and field-level costs and BCEI's estimate of the portion of its headquarters general and administrativeoverhead expenses necessary to operate the properties. Operating costs have been divided into field-level costs, per-well costs, and per-unit-of-productioncosts. Capital costs used by BCEI are based on authorizations for expenditure and actual costs from recent activity. Capital costs are included as required forworkovers, new development wells, and production equipment. Abandonment costs used are BCEI's estimates of the costs to abandon the wells andproduction facilities, net of any salvage value. Operating, capital, and abandonment costs are not escalated for inflation.The reserves shown in this report are estimates only and should not be construed as exact quantities. Proved reserves are those quantities of oil and gaswhich, by analysis of engineering and geoscience data, can be estimated with reasonable certainty to be economically producible; probable and possiblereserves are those additional reserves which are sequentially less certain to be recovered than proved reserves. Estimates of reserves may increase or decrease as a result of market conditions, future operations, changes in regulations, or actual reservoirperformance. In addition to the primary economic assumptions discussed herein, estimates of BCEI and NSAI are based on certain assumptions including,but not limited to, that the properties will be developed consistent with current development plans as provided to us by BCEI, that the properties will beoperated in a prudent manner, that no governmental regulations or controls will be put in place that would impact the ability of the interest owner to recoverthe reserves, and that projections of future production will prove consistent with actual performance. If thereserves are recovered, the revenues therefrom and the costs related thereto could be more or less than the estimated amounts. Because of governmentalpolicies and uncertainties of supply and demand, thesales rates, prices received for the reserves, and costs incurred in recovering such reserves may vary from assumptions made while preparing theseestimates.It should be understood that our audit does not constitute a complete reserves study of the audited oil and gas properties. Our audit consisted primarily ofsubstantive testing, wherein we conducted a detailed review of all properties. In the conduct of our audit, we have not independently verified the accuracyand completeness of information and data furnished by BCEI with respect to ownership interests, oil and gas production, well test data, historical costs ofoperation and development, product prices, or any agreements relating to current and future operations of the properties and sales of production. However, ifin the course of our examination something came to our attention that brought into question the validity or sufficiency of any such information or data, we didnot rely on such information or data until we had satisfactorily resolved our questions relating thereto or had independently verified such information or data.Our audit did not include a review of BCEI's overall reserves management processes and practices.We used standard engineering and geoscience methods, or a combination of methods, including performance analysis, volumetric analysis, and analogy,that we considered to be appropriate and necessary to establish the conclusions set forth herein. As in all aspects of oil and gas evaluation, there areuncertainties inherent in the interpretation of engineering and geoscience data; therefore, our conclusions necessarily represent only informed professionaljudgment.Supporting data documenting this audit, along with data provided by BCEI, are on file in our office. The technical persons primarily responsible for conductingthis audit meet the requirements regarding qualifications, independence, objectivity, and confidentiality set forth in the SPE Standards.
