Among the factors that could cause actual results to rldwide economic conditions and other variables worldwide economic conditions an Current SEC rules regarding oil and gas reserves information allow oil and gas companies to disclose in ﬁlings with the SEC not only proved reserves, but also probable and possible reserves that meet the SEC’s deﬁnitions of such terms. We disclose only proved reserves in our ﬁlings with the SEC. Denbury’s proved reserves as of December 31, 2016 were estimated by DeGolyer & MacNaughton, an independent petroleum engineering ﬁrm. In this annual report, we may make reference to probable and possible reserves, some of which have been estimated by our independent engineers and some of which have been estimated by Denbury’s internal staff of engineers. In this annual report, we also may refer to estimates of original oil in place, resource or reserves “potential,” barrels recoverable, or other descriptions of volumes potentially recoverable, which in addition to reserves generally classiﬁable as probable and possible (2P and 3P reserves), include estimates of resources that do not rise to the standards for possible reserves, and which SEC guidelines strictly prohibit us from including in ﬁlings with the SEC. These estimates, as well as the estimates of probable and possible reserves, are by their nature more speculative than estimates of proved reserves and are subject to greater uncertainties, and accordingly the likelihood of recovering those reserves is subject to substantially greater risk.

See “Forward-looking Statements” for additional information. (3) Excludes additional potential related to non-tertiary exploitation opportunities. DEAR FELLOW SHAREHOLDERS The last two years have presented a challenging forecasted by many of our industry peers as prices environment as the industry has endured the most improve. Accordingly, we anticipate that many of signiﬁcant and prolonged oil price downturn in our cost reductions will be sustainable, allowing history. After hitting a 14-year low of $26 per barrel us to develop our high-quality assets and expand our in February, oil prices generally increased throughout competitive operating margins. 2016, ending the year at around $50 per barrel, supported in large part by the agreement of the Organization of Petroleum Exporting Countries (“OPEC”) and certain non-OPEC countries to limit production. While we now see prospects for more long-term stability in the oil markets with a near balance of supply and demand, there is still a great deal of uncertainty around the near-term direction of oil prices, mainly driven by persistent high oil inventory levels, the recent sharp increase in shale drilling activity, and concerns about the duration of the commitment of OPEC and others to curtail production. Our business optimization efforts have not only generated signiﬁcant cost savings to date, but they will provide additional beneﬁts in the revamping of future projects. One of our more signiﬁcant achievements is our improvement in CO2 utilization. This was accomplished through a complete utilization re-evaluation, ensuring that injected volumes of CO2 were generating the intended beneﬁts and identifying areas for improvement. As a result of this work, we lowered our total company CO2 usage in 2016 by 44% from early 2015, or, stated another way, we reduced our injection of nearly one billion cubic feet of CO2 per At Denbury, we responded quickly to the decline in oil day in early 2015, to an average of just over 500 million prices, reducing our 2015 capital expenditures by cubic feet per day in 2016. In addition to lowering our over 60% from 2014, then reducing our 2016 capital by operating costs, this reduction in usage brings almost 50% from 2015. Our focus throughout this signiﬁcant additional beneﬁts to our long-range plans. down cycle has been on the execution of four core goals: In the past, CO2 supply and distribution had been a reducing costs, optimizing our business, reducing potential limiting factor in our long-term plans for debt, and preserving cash and liquidity. We believe our developing our ﬂoods. With this improved CO2 efﬁciency, results on the execution of these core goals has been our CO2 supply at Jackson Dome, where we are signiﬁcant and impactful. currently producing at less than 60% of the operational We completed a robust review of each of our ﬁelds, identifying multiple opportunities to enhance value, including through the expansion and optimization of currently producing ﬁelds, as well as via other exploitation opportunities. During 2016, we reduced our full-year cash operating costs (including general and administrative costs and interest) by over $2 per barrel capacity, can service additional future CO2 ﬂoods. We also expect to begin taking CO2 deliveries from Mississippi Power’s Kemper County power plant in the ﬁrst half of 2017. Combined, this additional CO2 supply capacity presents many new opportunities to expand our business beyond what we previously thought practicable. of oil equivalent from 2015, and by over $9 per barrel In addition to CO2 utilization efﬁciencies, we created of oil equivalent since 2014. On an absolute-dollar basis, further value in 2016 by constructing a natural gas we lowered our combined lease operating and general liquids plant at Delhi Field in Louisiana, executing a and administrative expenses by nearly $135 million, joint venture at Grieve Field that will accelerate or 20%, from 2015, and by $281 million, or 35%, development without corresponding capital compared to 2014. Although a portion of these savings requirements, and divesting of assets that did not ﬁt is attributable to lower supplier costs, we do not into our core asset proﬁle. The natural gas liquids plant expect to experience the same level of inﬂation at Delhi Field, our largest capital expenditure item placing us on an upward trajectory to resume modest of 2016, came online in late 2016, as expected. The plant production growth near the end of 2017 and into 2018. is working as designed to separate natural gas Much of our development capital will be directed liquids from the CO2 recycle stream for sale, generate toward continued development of our existing tertiary power from methane, and facilitate higher ﬂood ﬂoods, where we have an ample inventory of projects sweep efﬁciencies. with strong rates of return at current oil prices. In addition We also took advantage of disconnected and volatile market conditions in 2016 to signiﬁcantly reduce our debt, while preserving cash and liquidity. During 2016, we completed a series of privately negotiated debt exchanges and open-market debt repurchases, contributing to a net reduction of our debt principal balance of over $530 million since the end of 2015. When to this tertiary spending, a portion of the planned spending will be dedicated to our non-tertiary properties, with a smaller amount directed toward exploitation opportunities. In addition, as Denbury has historically done, we continue to look for acquisition opportunities that could allow us to accelerate growth and expand our inventory of future development opportunities. combined with the paydown of our debt with excess To summarize, we are optimistic about what lies ahead. cash ﬂow in 2015, we have realized a net debt reduction We have made signiﬁcant improvements in our of nearly $800 million since the end of 2014.

We are certainly pleased over the past two years have made Denbury a with the sizable progress we have made in reducing stronger company. We believe that our strong base of our debt and maintaining our liquidity, but, in the long-lived low-decline oil assets, strategic CO2 supply and current price environment, our leverage metrics are not distribution capacity, and unique enhanced oil where we would like them to be. During 2017, we will recovery expertise all combine to set the stage for a continue to evaluate and pursue opportunities to great future for Denbury. improve our balance sheet and debt metrics, as well as proactively manage our bank credit facility to preserve our liquidity. Looking forward, we are excited with the projects we have planned for 2017. In mid-February 2017, we announced an increase in our estimated capital budget from $209 million in 2016 to $300 million in 2017, with anticipated spending within, or very close to, our cash ﬂow from operations in 2017, based on market prices at that date. We will continue to maintain ﬂexibility in our capital program to adapt to changes in the oil price outlook, as appropriate. We expect this capital spending level should hold our 2017 average production rate roughly ﬂat with our 2016 exit rate of just under 60,000 barrels of oil equivalent per day, Sincerely, Phil Rykhoek Chief Executive Ofﬁcer March 30, 2017 DENBURY’S CO2 CYCLE Step 1 Step 2 Step 3 Step 4 CO2 SOURCES & CAPTURE CO2 TRANSPORTATION CO2 INJECTION CO2 EOR BENEFITS & STORAGE The ﬁrst step in implementing a The second step is transporting The third step is to inject the CO2 EOR operations provide carbon dioxide enhanced oil the CO2 from the source to the CO2 into the oil-bearing considerable economic and recovery (“CO2 EOR”) project is to oil ﬁeld.

Business and Properties GENERAL Denbury Resources Inc., a Delaware corporation, is an independent oil and natural gas company with 254.5 MMBOE of estimated proved oil and natural gas reserves as of December 31, 2016, of which 97% is oil. Our operations are focused in two key operating areas: the Gulf Coast and Rocky Mountain regions. Our goal is to increase the value of our properties through a combination of exploitation, drilling and proven engineering extraction practices, with the most significant emphasis relating to CO2 enhanced oil recovery operations. As part of our corporate strategy, we are committed to strong financial discipline, efficient operations and creating long- term value for our shareholders through the following key principles: • • • target specific regions where we either have, or believe we can create, a competitive advantage as a result of our ownership or use of CO2 reserves, oil fields and CO2 infrastructure; secure properties where we believe additional value can be created through tertiary recovery operations and a combination of other exploitation, development, exploration and marketing techniques; acquire properties that give us a majority working interest and operational control or where we believe we can ultimately obtain it; • maximize the value and cash flow generated from our operations by increasing production and reserves while controlling costs; optimize the timing and allocation of capital among our investment opportunities to maximize the rates of return on our investments; exercise financial discipline by attempting to balance our development capital expenditures with our cash flows from operations; and attract and maintain a highly competitive team of experienced and incentivized personnel. • • • Denbury has been publicly traded on the New York Stock Exchange since 1997. Our corporate headquarters is located at 5320 Legacy Drive, Plano, Texas 75024, and our phone number is 972-673-2000. At December 31, 2016, we had 1,058 employees, 577 of whom were employed in field operations or at our field offices. We make our annual report on Form 10- K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports, filed or furnished pursuant to section 13(a) or 15(d) of the Securities Exchange Act of 1934, available free of charge on or through our website, www.denbury.com, as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. The public may read and copy any materials we file with the SEC at the SEC’s Public Reference Room at 100 F Street, NE, Washington, DC 20549. The public may obtain information on the operation of the Public Reference Room by calling the SEC at 1-800-SEC-0330. The SEC also maintains a website, http://www.sec.gov, which contains reports, proxy and information statements and other information filed by Denbury. Throughout this Annual Report on Form 10-K (“Form 10- K”) we use the terms “Denbury,” “Company,” “we,” “our” and “us” to refer to Denbury Resources Inc. and, as the context may require, its subsidiaries. 2016 BUSINESS DEVELOPMENTS Oil prices generally constitute the single largest variable in our operating results. Oil prices have historically been volatile, with NYMEX oil prices ranging from $26 to $107 per Bbl over the last three calendar years, with prices in February 2016 representing the lowest level in over 14 years. Although realized prices have increased from the lows experienced during the first quarter of 2016, our focus continues to remain on cost reductions and preserving liquidity. Our 2016 business developments included the following: • Generated $219.2 million of cash flow from operations (which amount includes $84.2 million of receipts on settlements of commodity derivatives) in 2016, which was $10.6 million higher than our incurred development capital expenditures ($208.6 million). 5 Denbury Resources Inc. • Reduced our cash operating costs, including corporate overhead and interest, to approximately $34 per BOE during 2016, a 7% decrease from similar levels during 2015, and reflects improved CO2 efficiency resulting in a 32% decrease in CO2 usage between 2015 and 2016. • Completed a series of privately negotiated debt exchanges and open-market debt repurchases, contributing to a net reduction of our debt principal balance of approximately $530.4 million during 2016. As a result of the reduction in our average debt outstanding, cash interest expense also decreased $11.5 million between 2015 and 2016. • Generated average total production of 64,003 BOE/d in 2016, an 11% decrease from 2015 production levels when adjusted for asset sales, despite reducing 2016 development capital spending to approximately half of 2015 levels. • Modified certain of our financial performance covenants applicable to the 2016, 2017 and 2018 periods to provide more flexibility in managing our balance sheet, the credit extended by our lenders, and continuing compliance with financial performance covenants in this low oil price environment. In addition, maintained the $1.05 billion borrowing base under our senior secured bank credit facility, providing us with significant liquidity. • Completed construction of a natural gas liquids extraction plant at Delhi Field, providing us with the ability to sell natural gas liquids from the produced stream, improve the efficiency of the CO2 flood, and utilize extracted methane to power the plant and reduce field operating expenses. • Revised the joint venture arrangement at Grieve Field to provide for our joint venture partner to fund up to $55 million of the remaining estimated capital to complete development of the facility and fieldwork in exchange for a 14% higher working interest and a disproportionate share of revenues from the first 2 million barrels of production. • Completed a process of evaluating our assets with a goal of increasing the value of both existing assets and future projects by optimizing field operational and development plans, identifying exploitation opportunities, reducing CO2 injection volumes through increased efficiency, and reducing costs. 2017 BUSINESS OUTLOOK Beginning in mid-2016, NYMEX oil prices reversed the previous sustained downward trend, increasing to per-barrel prices in the low $50’s in late 2016 and early 2017. While these NYMEX oil prices are an improvement from the lows experienced in February 2016, we continue to exercise caution when determining capital budgets and finalizing field development plans, as our primary focus continues to be on preserving our financial strength and flexibility. Given expectations around oil prices using 2017 NYMEX oil futures and our current hedging levels, our 2017 capital spending has initially been budgeted at approximately $300 million, excluding capitalized interest and acquisitions, an increase of 44% over 2016 spending levels. With this increased capital spending level, we currently anticipate 2017 average daily production will remain relatively flat with our exit rate in 2016 of roughly 60,000 BOE/d. Based upon our current production forecast and hedges currently in place, using expected average oil prices in the mid-$50’s per barrel during 2017, we currently expect that our operations would internally fund all but a minor amount of our 2017 capital spending budget of $300 million. We currently intend to fund any potential shortfall with incremental borrowings on our senior secured bank credit facility, and as of December 31, 2016, we had ample availability on our senior secured bank credit facility to cover any foreseeable cash flow shortfall. Our capital spending during 2017 will focus primarily on the continued development of our current tertiary floods, with less focus on the development of unproved reserves. Planned development activities presented in the discussions that follow may be delayed or modified during the course of 2017 depending primarily upon oil prices and our level of cash flow to fund such development, and we will continue to evaluate the timing of the development of our inventory of fields and related pipelines and facilities. Additionally, we plan to continue our focus on improving our balance sheet, maintaining and enhancing the efficiencies achieved over the last couple of years and pursuing opportunities to increase or accelerate growth. We believe the market for acquisitions is improving and under the right conditions and terms acquisitions could provide one potential way to enhance our growth. In light of this, we are focusing on acquisition efforts directed at oil properties, preferably in our two areas of operation, in a manner that is accretive and does not significantly increase our leverage or reduce our liquidity. 6 ESTIMATED NET QUANTITIES OF PROVED OIL AND NATURAL GAS RESERVES AND PRESENT VALUE OF ESTIMATED FUTURE NET REVENUES Denbury Resources Inc. Oil and Natural Gas Reserve Estimates DeGolyer and MacNaughton (“D&M”) prepared estimates of our net proved oil and natural gas reserves as of December 31, 2016, 2015 and 2014 (see the summary of D&M’s report as of December 31, 2016, included as an exhibit to this Form 10-K). These estimates of reserves were prepared using an average price equal to the unweighted arithmetic average of hydrocarbon prices on the first day of each month within the 12-month period in accordance with rules and regulations of the SEC. These oil and natural gas reserve estimates do not include any value for probable or possible reserves that may exist, nor do they include any value for undeveloped acreage. The reserve estimates represent our net revenue interest in our properties. The following table provides estimated proved reserve information prepared by D&M as of December 31, 2016, 2015 and 2014, as well as PV-10 Values and Standardized Measures for each period. There are numerous uncertainties inherent in estimating quantities of proved oil and natural gas reserves and their values, including many factors beyond our control. Proved oil and natural gas reserve quantities and values presented in the table reflect the significant decline in commodity prices beginning in late 2014 and continuing through 2016, whereby the average first-day-of-the-month NYMEX oil price used in estimating our proved reserves declined from $94.99 per Bbl at December 31, 2014, to $42.75 per Bbl at December 31, 2016, and for natural gas declined from $4.30 per MMBtu at December 31, 2014, to $2.55 per MMBtu at December 31, 2016. These commodity price changes contributed to the largest portion of the decline in proved reserves, including a decline of approximately 126 MMBOE (29%) in our proved reserves from December 31, 2014, to December 31, 2015, approximately half of which was attributable to natural gas reserves at Riley Ridge that were reclassified and are no longer considered proved reserves. See also Oil and Natural Gas Operations – Field Summary Table, Item 1A, Risk Factors – Estimating our reserves, production and future net cash flows is difficult to do with any certainty, and Supplemental Oil and Natural Gas Disclosures (Unaudited) to the Consolidated Financial Statements for further discussion of reserve inputs and changes between periods.

As a result of this decrease, natural gas reserves at Riley Ridge were reclassified and are no longer considered proved reserves, and which reserves totaled approximately 368 Bcf (61 MMBOE) as of December 31, 2014, or approximately 81% of our total proved natural gas reserves at that date. (2) The reference prices were based on the arithmetic average of the first-day-of-the-month NYMEX commodity prices for each month during the respective year. These prices do not reflect adjustments for market differentials by field that are utilized in the preparation of our reserve report to arrive at the appropriate net price we receive. See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations – Operating Results Table for details of oil and natural gas prices received, both including and excluding the impact of derivative settlements. (3) Determined based on the average first-day-of-the-month prices for each month, adjusted to prices received by field in accordance with standards set forth in the Financial Accounting Standards Board Codification (“FASC”). PV-10 Values and the Standardized Measure are significantly impacted by the oil prices we receive relative to NYMEX oil prices (our NYMEX oil price differential). The weighted-average oil price differentials utilized were $3.39 per Bbl below representative NYMEX oil prices as of December 31, 2016, compared to $2.17 per Bbl below NYMEX oil prices as of December 31, 2015, and $3.10 per Bbl below NYMEX oil prices as of December 31, 2014. (4) PV-10 Value is a non-GAAP measure and is different from the Standardized Measure in that PV-10 Value is a pre-tax number and the Standardized Measure is an after-tax number. The information used to calculate PV-10 Value is derived directly from data determined in accordance with FASC Topic 932. The difference between these two amounts, the discounted estimated future income tax, was $142.5 million at December 31, 2016; $428.4 million at December 31, 2015; and $2.84 billion at December 31, 2014. We believe that PV-10 Value is a useful supplemental disclosure to the Standardized Measure because the Standardized Measure can be impacted by a company’s unique tax situation, and it is not practical to calculate the Standardized Measure on a property-by-property basis. Because of this, PV-10 Value is a widely used measure within the industry and is commonly used by securities analysts, banks and credit rating agencies to evaluate the estimated future net cash flows from proved reserves on a comparative basis across companies or specific properties. PV-10 Value is commonly used by us and others in our industry to evaluate properties that are bought and sold, to assess the potential return on investment in our oil and natural gas properties, and to perform our impairment testing of oil and natural gas properties. PV-10 Value is not a measure of financial or operating performance under GAAP, nor should it be considered in isolation or as a substitute for the Standardized Measure. Our PV-10 Value and the Standardized Measure do not purport to represent the fair value of our oil and natural gas reserves. See Glossary and Selected Abbreviations for the definition of “PV-10 Value” and see Supplemental Oil and Natural Gas Disclosures (Unaudited) to the Consolidated Financial Statements for additional disclosures about the Standardized Measure. Our proved non-producing reserves primarily relate to reserves that are to be recovered from productive zones that currently require a response to performance modifications before they can be classified as proved developed producing. Since a majority of our properties are in areas with multiple pay zones, these properties may have both proved producing and proved non-producing reserves. As of December 31, 2016, our estimated proved undeveloped reserves totaled approximately 45.2 MMBOE, or approximately 18% of our estimated total proved reserves, a decline of 14.0 MMBOE from December 31, 2015 levels for these reserves, which changes are discussed below. Approximately 91% (41 MMBOE) of our proved undeveloped oil reserves 8 Denbury Resources Inc. relate to our CO2 tertiary operations. We generally consider the CO2 tertiary proved undeveloped reserves to be lower risk than other proved undeveloped reserves that require drilling at locations offsetting existing production, because all of these proved undeveloped reserves are associated with tertiary recovery operations in fields and reservoirs that historically produced substantial volumes of oil under primary production. As of December 31, 2016, 12.6 MMBOE of our total proved undeveloped reserves are not scheduled to be developed within five years of initial booking, all of which are part of CO2 EOR projects. We believe these reserves satisfy the conditions to be included as proved reserves because (1) we have established and continue to follow the previously adopted development plan for each of these projects; (2) we have significant ongoing development activities in each of these CO2 EOR projects and (3) we have a historical record of completing the development of comparable long-term projects. During 2016, we spent approximately $45 million to convert 5.9 MMBOE of proved undeveloped reserves to proved developed reserves, primarily related to continued tertiary development activities at Delhi Field, as well as non-tertiary development at Cedar Creek Anticline (“CCA”). Other changes during 2016 included adding 3.9 MMBOE of proved undeveloped reserves primarily related to our tertiary operations at Heidelberg Field; reclassifying 6.7 MMBOE of proved undeveloped reserves to unproved reserves pursuant to the five-year development rule established by the SEC primarily due to changes in our development plans; and recognizing other net downward proved undeveloped reserve revisions of 5.3 MMBOE, primarily the result of reserves that were determined to be uneconomic based on 2016 average oil and natural gas prices used in estimating our proved reserves. During 2016, we provided oil and natural gas reserve estimates for 2015 to the United States Energy Information Agency that were substantially the same as the reserve estimates included in our Form 10-K for the year ended December 31, 2015. Internal Controls Over Reserve Estimates Reserve information in this report is based on estimates prepared by D&M, an independent petroleum engineering consulting firm located in Dallas, Texas, utilizing data provided by our internal reservoir engineering team and is the responsibility of management. We rely on D&M’s expertise to ensure that our reserve estimates are prepared in compliance with SEC rules and regulations and that appropriate geologic, petroleum engineering, and evaluation principles and techniques are applied in accordance with practices generally recognized by the petroleum industry as presented in the publication of the Society of Petroleum Engineers entitled “Standards Pertaining to the Estimating and Auditing of Oil and Gas Reserves Information (Revision as of February 19, 2007)”. The person responsible for the preparation of the reserve report is a Senior Vice President at D&M; he is a Registered Professional Engineer in the State of Texas. He received a Master of Science degree in Petroleum Engineering from the University of Texas in 1975, and he has in excess of 37 years of experience in oil and gas reservoir studies and evaluations. Our President and Chief Operating Officer is primarily responsible for overseeing the independent petroleum engineering firm during the process. Our President and Chief Operating Officer has a Bachelor of Science degree in Engineering, Civil Specialty, from the Colorado School of Mines and over 27 years of industry experience working with petroleum reserve estimates. D&M relies on various data provided by our internal reservoir engineering team in preparing its reserve estimates, including such items as oil and natural gas prices, ownership interests, production information, operating costs, planned capital expenditures and other technical data. Our internal reservoir engineering team consists of qualified petroleum engineers who maintain the Company’s internal evaluation of reserves and compare the Company’s information to the reserves prepared by D&M. Management is responsible for designing the internal control procedures used in the preparation of our oil and gas reserves, which include verification of data input into reserve forecasting and economics evaluation software, as well as multi-discipline management reviews. The internal reservoir engineering team reports directly to our President and Chief Operating Officer. In addition, our Board of Directors’ Reserves and Health, Safety and Environmental (“HSE”) Committee, on behalf of the Board of Directors, oversees the qualifications, independence, performance and hiring of our independent petroleum engineering firm and reviews the final report and subsequent reporting of our oil and natural gas reserve estimates. The Chairman of the Reserves and HSE Committee holds a Ph.D. in Chemical Engineering from the Massachusetts Institute of Technology and bachelor’s degrees in Chemistry and Mathematics from Capital University in Ohio. He has more than 35 years of industry experience, with responsibilities including reserves preparation and approval. 9 OIL AND NATURAL GAS OPERATIONS Denbury Resources Inc. Summary. Our oil and natural gas properties are concentrated in the Gulf Coast and Rocky Mountain regions of the United States. Currently our properties with proved and producing reserves in the Gulf Coast region are situated in Mississippi, Texas, Louisiana and Alabama, and in the Rocky Mountain region are situated in Montana, North Dakota and Wyoming. Our primary focus is increasing the value of our properties through a combination of exploitation, drilling and proven engineering extraction practices, with the most significant emphasis relating to CO2 EOR operations. Our current portfolio of CO2 EOR projects provides us significant oil production and reserve growth potential in the future, assuming crude oil prices are at levels that support the development of those projects. We have been conducting and expanding EOR operations on our assets in the Gulf Coast region since 1999, and as a result, we currently have many more CO2 EOR projects in this region than in the Rocky Mountain region. We began operations in the Rocky Mountain region in 2010 in connection with, and following, our merger with Encore Acquisition Company (“Encore”). In the Gulf Coast region, we own what is, to our knowledge, the region’s only significant naturally occurring source of CO2, and these large volumes of naturally occurring CO2 give us a significant competitive advantage in this area. In the Rocky Mountain region, we own an overriding royalty interest equivalent to an approximate one-third ownership interest in ExxonMobil Corporation’s (“ExxonMobil’s”) CO2 reserves in LaBarge Field in southwestern Wyoming. In addition to the sources of CO2 we currently own, we purchase and use CO2 captured from industrial sources which could otherwise be released into the atmosphere (sometimes referred to as anthropogenic, man-made or industrial-source CO2) in our tertiary operations. These industrial sources of CO2 help us recover additional oil from mature oil fields and, we believe, also provide an economical way to reduce atmospheric CO2 emissions through the concurrent underground storage of CO2 which occurs as part of our oil-producing EOR operations. 10 Denbury Resources Inc. Field Summary Table. The following table provides a summary by field and region of selected proved oil and natural gas reserve information, including total proved reserve quantities and the associated PV-10 Value of those reserves as of December 31, 2016, and average daily production for 2016, all based on Denbury’s net revenue interest (“NRI”). The reserve estimates presented were prepared by D&M, independent petroleum engineers located in Dallas, Texas. We serve as operator of virtually all of our significant properties, in which we also own most of the interests, although typically less than a 100% working interest, and a lesser NRI due to royalties and other burdens.

(2) PV-10 Value is a non-GAAP measure and is different from the GAAP measure, the Standardized Measure, in that PV-10 Value is a pre-tax number and the Standardized Measure is an after-tax number. The Standardized Measure was $1.4 billion at December 31, 2016. A comparison of PV-10 Value to the Standardized Measure is included in the reserves table in Estimated Net Quantities of Proved Oil and Natural Gas Reserves and Present Value of Estimated Future Net Revenues above. The information used to calculate the PV-10 Value is derived directly from data determined in accordance with FASC Topic 932. See the definition of PV-10 Value in the Glossary and Selected Abbreviations. 11 Denbury Resources Inc. (3) Mature properties include Brookhaven, Cranfield, Eucutta, Little Creek, Mallalieu, Martinville, McComb and Soso fields in Mississippi and Lockhart Crossing Field in Louisiana. (4) The Cedar Creek Anticline consists of a series of 14 different operating areas. Enhanced Oil Recovery Overview. CO2 used in EOR is one of the most efficient tertiary recovery mechanisms for producing crude oil. When injected under pressure into underground, oil-bearing rock formations, CO2 acts somewhat like a solvent as it travels through the reservoir rock, mixing with and modifying the characteristics of the oil so it can be produced and sold. The terms “tertiary flood,” “CO2 flood” and “CO2 EOR” are used interchangeably throughout this document. While enhanced oil recovery projects utilizing CO2 have been successfully performed by numerous oil and gas companies in a wide range of oil-bearing reservoirs in different oil-producing basins, we believe our investments, experience and acquired knowledge give us a strategic and competitive advantage in the areas in which we operate. We apply what we have learned and developed over the years to improve and increase sweep efficiency within the CO2 EOR projects we operate. We began our CO2 operations in August 1999, when we acquired Little Creek Field, followed by our acquisition of Jackson Dome CO2 reserves and the NEJD pipeline in 2001. Based upon our success at Little Creek and the ownership of the CO2 reserves, we began to transition our capital spending and acquisition efforts to focus more heavily on CO2 EOR and, over time, transformed our strategy to focus primarily on owning and operating oil fields that are well suited for CO2 EOR projects. Prior to tertiary flooding, we strive to maximize the currently sizeable primary and secondary production from our prospective tertiary fields and from fields in which tertiary floods have commenced but still contain significant non-tertiary production. Our asset base today almost entirely consists of, or otherwise relates to, oil fields that we are currently flooding with CO2 or plan to flood with CO2 in the future, or assets that produce CO2. Our tertiary operations have grown so that (1) 59% of our proved reserves at December 31, 2016 are proved tertiary oil reserves; (2) 60% of our 2016 total production was related to tertiary oil operations (on a BOE basis); and (3) 80% of our 2016 capital expenditures (excluding acquisitions) were related to our tertiary oil operations. At year-end 2016, the proved oil reserves in our tertiary recovery oil fields had an estimated PV-10 Value of approximately $943.8 million, or 61% of our total PV-10 Value. In addition, there are significant probable and possible reserves at several other fields for which tertiary operations are underway or planned. Although the up-front cost of tertiary production infrastructure and time to construct pipelines and production facilities is greater than in primary oil recovery in most circumstances, we believe tertiary recovery has several favorable, offsetting and unique attributes, including (1) a lower exploration risk, as we are operating oil fields that have significant historical production and reservoir and geological data, (2) reasonable return metrics at our anticipated long-term prices, (3) limited competition for this recovery method in our geographic regions and a strategic advantage due to our ownership of the CO2 reserves and CO2 pipeline infrastructure, (4) our EOR operations are generally less disruptive to new habitats in comparison to other oil and natural gas development because we further develop existing (as opposed to new) oil fields, and (5) through our oil-producing EOR operations, we concurrently store CO2 captured from industrial sources in the same underground formations that previously trapped and stored oil and natural gas. Tertiary Oil Properties Gulf Coast Region CO2 Sources and Pipelines Jackson Dome. Our primary Gulf Coast CO2 source, Jackson Dome, located near Jackson, Mississippi, was discovered during the 1970s by oil and gas companies that were exploring for hydrocarbons. This large and relatively pure source of naturally occurring CO2 (98% CO2) is, to our knowledge, the only significant underground deposit of CO2 in the United States east of the Mississippi River. Together with the related CO2 pipeline infrastructure, Jackson Dome provides us a significant strategic advantage in the acquisition of properties in Mississippi, Louisiana and southeastern Texas that are well suited for CO2 EOR. 12 Denbury Resources Inc. We acquired Jackson Dome in February 2001 in a purchase that also gave us ownership and control of the NEJD CO2 pipeline and provided us with a reliable supply of CO2 at a reasonable and predictable cost for our Gulf Coast CO2 tertiary recovery operations. Since February 2001, we have acquired and drilled numerous CO2-producing wells, significantly increasing our estimated proved Gulf Coast CO2 reserves from approximately 800 Bcf at the time of acquisition of Jackson Dome to approximately 5.3 Tcf as of December 31, 2016. The proved CO2 reserve estimates are based on a gross (8/8ths) basis, of which our net revenue interest is approximately 4.2 Tcf, and is included in the evaluation of proved CO2 reserves prepared by D&M, an independent petroleum engineering consulting firm. In discussing our available CO2 reserves, we make reference to the gross amount of proved and probable reserves, as this is the amount that is available both for our own tertiary recovery programs and for industrial users who are customers of Denbury and others, as we are responsible for distributing the entire CO2 production stream. In addition to our proved reserves, we estimate that we have 1.2 Tcf of probable CO2 reserves at Jackson Dome. While the majority of these probable reserves are located in structures that have been drilled and tested, such reserves are still considered probable reserves because (1) the original well is plugged; (2) they are located in fault blocks that are immediately adjacent to fault blocks with proved reserves; or (3) they are reserves associated with increasing the ultimate recovery factor from our existing reservoirs with proved reserves. In addition, a significant portion of these probable reserves at Jackson Dome are located in undrilled structures where we have sufficient subsurface and seismic data indicating geophysical attributes that, coupled with our historically high drilling success rate, provide a reasonably high degree of certainty that CO2 is present. In addition to our drilling at Jackson Dome, we continue to expand our processing and dehydration capacities, and we continue to install pipelines and/or pumping stations necessary to transport the CO2 through our controlled pipeline network. As part of our innovation and improvement initiative, we have identified fields where we have been able to reduce CO2 injections without significantly impacting production. As such, we have been able to reduce injected CO2 volumes in the Gulf Coast region by 23% when comparing injection levels in the fourth quarter of 2016 to those in the prior year fourth quarter. We expect our current proved reserves of CO2, coupled with a risked drilling program at Jackson Dome and CO2 expected to be captured from industrial sources, to provide sufficient quantities of CO2 for us to develop our proved and probable EOR reserves in the Gulf Coast region. In the future, we believe that once a CO2 flood in a field reaches its productive economic limit, we could recycle a portion of the CO2 that remains in that field’s reservoir and utilize it for oil production in another field’s tertiary flood. In the Gulf Coast region, approximately 85% of our average daily CO2 produced from Jackson Dome or captured from industrial sources in 2016 was used in our tertiary recovery operations, compared to 88% in 2015 and 91% in 2014, with the balance delivered to third-party industrial users. During 2016, we used an average of 462 MMcf/d of CO2 (including CO2 captured from industrial sources) for our tertiary activities. Gulf Coast CO2 Captured from Industrial Sources. In addition to our natural source of CO2, we are currently party to three long-term contracts to purchase CO2 from industrial plants. We have purchased CO2 from an industrial facility in Port Arthur, Texas since 2012 and from an industrial facility in Geismar, Louisiana since 2013, which currently supply approximately 55 MMcf/d of CO2 to our EOR operations. We currently expect to begin purchasing CO2 from Mississippi Power’s Kemper County Energy Facility during the first half of 2017, which could more than double the amount of CO2 we currently utilize from industrial sources. Additionally, we are in ongoing discussions with other parties who have plans to construct plants near the Green Pipeline. One of these projects includes construction of a methanol plant in Lake Charles, Louisiana, which is currently in the project financing stage of development. If the project is successfully financed in 2017, we would not expect first deliveries of CO2 from the plant until 2021 at the earliest. In October 2015, the Environmental Protection Agency (“EPA”) finalized a rule – Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units (also known or commonly referred to as the “Clean Power Plan”) – that would impose limits on greenhouse gas emissions from new and existing U.S. electric generation units. The Clean Power Plan in its current form contains requirements which would likely impact our ability to purchase power plant CO2 for our EOR operations from Mississippi Power’s Kemper County Energy Facility. The Clean Power Plan has been challenged by various states, trade associations, companies (including Denbury) and environmental groups. On February 9, 2016, the U.S. Supreme Court stayed the implementation of the Clean Power Plan pending resolution of various challenges to the rule. On September 27, 2016, an en banc panel of the U.S. Court of Appeals for the District of Columbia Circuit heard oral argument on the merits of the various challenges to the Clean Power Plan. A decision could be issued at any time. In the meantime, the Supreme Court’s stay of the rule is in place and is expected to remain so until it grants certiorari and issues 13 Denbury Resources Inc. its own decision on the Plan, possibly as late as summer 2018. Additionally, the Trump administration has announced its intention to revise or rescind the Clean Power Plan. Given the Clean Power Plan’s status as a “final rule,” any change or revocation would likely involve a new rule-making process or Congressional action, the timing and details of which cannot be predicted. Although we do not believe the Clean Power Plan will impact our ability to take CO2 from Mississippi Power’s Kemper County Energy Facility in the near term, it could limit our ability to take CO2 in the future if upheld and maintained in effect. In addition to the potential CO2 sources discussed above, we continue to have ongoing discussions with owners of existing plants of various types that emit CO2 that we may be able to purchase and/or transport. In order to capture such volumes, we (or the plant owner) would need to install additional equipment, which includes, at a minimum, compression and dehydration facilities. Most of these existing plants emit relatively small volumes of CO2, generally less than our contracted sources, but such volumes may still be attractive if the source is located near CO2 pipelines. The capture of CO2 could also be influenced by possible legislation or regulatory orders pertaining to CO2 emissions. We believe that we are a likely purchaser of CO2 captured in our areas of operation because of the scale of our tertiary operations and our CO2 pipeline infrastructure. Gulf Coast CO2 Pipelines. We acquired the 183-mile NEJD CO2 pipeline that runs from Jackson Dome to near Donaldsonville, Louisiana, as part of the 2001 acquisition of our Jackson Dome CO2 source. Since 2001, we have acquired or constructed nearly 750 miles of CO2 pipelines, and as of December 31, 2016, we have access to nearly 950 miles of CO2 pipelines, which gives us the ability to deliver CO2 throughout the Gulf Coast region. In addition to the NEJD CO2 pipeline, the major pipelines in the Gulf Coast region are the Free State Pipeline (90 miles), the Delta Pipeline (110 miles), the Green Pipeline Texas (120 miles), and the Green Pipeline Louisiana (200 miles). Completion of the Green Pipeline allowed for the first CO2 injection into Hastings Field, located near Houston, Texas, in 2010, and gives us the ability to deliver CO2 to oil fields all along the Gulf Coast from Baton Rouge, Louisiana, to Alvin, Texas. At the present time, most of the CO2 flowing in the Green Pipeline is delivered from the Jackson Dome area, but also includes the CO2 we are receiving from the industrial facilities in Port Arthur, Texas and Geismar, Louisiana, and we are currently transporting a third party’s CO2 for a fee to the sales point at Hastings Field. We expect the volume of CO2 transported through the Green Pipeline to increase in future years as we develop our inventory of CO2 EOR projects in this area. Tertiary Properties with Tertiary Production and Proved Tertiary Reserves at December 31, 2016 Mature properties. Mature properties include our longest-producing properties which are generally located along our NEJD CO2 pipeline in southwest Mississippi and Louisiana and our Free State Pipeline in east Mississippi. This group of properties includes our initial CO2 field, Little Creek, as well as several other fields (Brookhaven, Cranfield, Eucutta, Lockhart Crossing, Mallalieu, Martinville, McComb and Soso fields). These fields accounted for 23% of our total 2016 CO2 EOR production and approximately 12% of our year-end proved tertiary reserves. These fields have been producing for some time, and their production is generally declining. Many of these fields contain multiple reservoirs that are amenable to CO2 EOR. Delhi Field. Delhi Field is located east of Monroe, Louisiana. In May 2006, we purchased our initial interest in Delhi for $50 million. We began well and facility development in 2008 and began delivering CO2 to the field in the fourth quarter of 2009 via the Delta Pipeline, which runs from Tinsley Field to Delhi Field. First tertiary production occurred at Delhi Field in the first quarter of 2010. Production from Delhi Field in the fourth quarter of 2016 averaged 4,387 Bbls/d, up from 3,898 Bbls/d in the fourth quarter of 2015. During late 2016, we completed construction of a natural gas liquids extraction plant, which provides us with the ability to sell natural gas liquids from the produced stream, improve the efficiency of the CO2 flood, and utilize extracted methane to power the plant and reduce field operating expenses. Our 2017 development capital budget includes investing approximately $20 million in this field, primarily related to continued phase development and infill drilling. Hastings Field. Hastings Field is located south of Houston, Texas. We acquired a majority interest in this field in February 2009 for $247 million. We initiated CO2 injection in the West Hastings Unit during the fourth quarter of 2010 upon completion of the construction of the Green Pipeline. Due to the large vertical oil column that exists in the field, we are developing the Frio reservoir using dedicated CO2 injection and producing wells for each of the major sand intervals. We began producing oil from our EOR operations at Hastings Field in the first quarter of 2012, and we booked initial proved tertiary reserves for the West Hastings Unit in 2012. During the fourth quarter of 2016, tertiary production from Hastings Field averaged 4,552 14 Denbury Resources Inc. Bbls/d, compared to 5,082 Bbls/d in the fourth quarter of 2015. Our 2017 development capital budget includes investing approximately $30 million in this field primarily related to continued tertiary development opportunities and conformance work. Heidelberg Field. Heidelberg Field is located in Mississippi and consists of an East Unit and a West Unit. Construction of the CO2 facility, connecting pipeline and well work commenced on the West Heidelberg Unit during 2008, with our first CO2 injections into the Eutaw zone in the fourth quarter of 2008. Our first tertiary oil production occurred in the second quarter of 2009, and we began flooding the Christmas and Tuscaloosa zones in 2013 and 2014, respectively. During the fourth quarter of 2016, tertiary production at Heidelberg Field averaged 4,924 Bbls/d, compared to 5,635 Bbls/d in the fourth quarter of 2015. Our future plans for Heidelberg Field include continued development of the East and West Heidelberg Units, including an expansion of our Tuscaloosa development and Christmas zone and adjustments to our CO2 floods of existing zones to better direct the CO2 through the zones and optimize oil recovery from the field, the ultimate timing of which will depend upon future oil prices or revised development plans. Our 2017 development capital budget includes investing approximately $35 million in this field, primarily related to developing portions of the Christmas Yellow sand in East Heidelberg and conformance work. Oyster Bayou Field. We acquired a majority interest in Oyster Bayou Field in 2007. The field is located in southeast Texas, east of Galveston Bay, and is somewhat unique when compared to our other CO2 EOR projects because the field covers a relatively small area of 3,912 acres. We began CO2 injections into Oyster Bayou Field in the second quarter of 2010, commenced tertiary production in the fourth quarter of 2011 from the Frio A-1 zone, and booked initial proved tertiary reserves for the field in 2012. In 2014, we completed development of the Frio A-2 zone. During the fourth quarter of 2016, tertiary production at Oyster Bayou Field averaged 4,988 Bbls/d, compared to 5,831 Bbls/d in the fourth quarter of 2015. Production from Oyster Bayou Field is believed to have peaked during 2015. Tinsley Field. We acquired Tinsley Field in 2006. This Mississippi field was discovered and first developed in the 1930s and is separated by different fault blocks. As is the case with the majority of fields in Mississippi, Tinsley Field produces from multiple reservoirs. Our CO2 enhanced oil recovery operations at Tinsley Field have thus far targeted the Woodruff formation, although there is additional potential in the Perry sandstone and other smaller reservoirs. We commenced tertiary oil production from Tinsley Field in the second quarter of 2008 and substantially completed development of the Woodruff formation during 2014. During the fourth quarter of 2016, average tertiary oil production from the field was 6,786 Bbls/d, compared to 7,522 Bbls/d in the fourth quarter of 2015. Although production from Tinsley Field is believed to have peaked in 2015, we continue to evaluate future potential investment opportunities in this field. Our 2017 development capital budget includes investing approximately $15 million in this field, primarily related to improvements at the recycle facility. Future Tertiary Properties with No Tertiary Production or Proved Tertiary Reserves at December 31, 2016 Webster Field. We acquired our interest in Webster Field in the fourth quarter of 2012. The field is located in Texas, approximately eight miles northeast of our Hastings Field which we are currently flooding with CO2. At December 31, 2016, Webster Field had estimated proved non-tertiary reserves of approximately 2.6 MMBOE, net to our interest. During the fourth quarter of 2016, non-tertiary production at Webster Field averaged 828 BOE/d, compared to 1,001 BOE/d in the fourth quarter of 2015. Webster Field is geologically similar to our Hastings Field, producing oil from the Frio zone at similar depths; as a result, we believe it is well suited for CO2 EOR. In 2014, we completed a nine-mile lateral between the Green Pipeline and Webster Field, which will eventually deliver CO2 to the field. The timing of CO2 injections at Webster Field is primarily dependent upon future oil prices. Conroe Field. Conroe Field, our largest potential tertiary flood in the Gulf Coast region, is located north of Houston, Texas. We acquired a majority interest in this field in 2009 for $271 million in cash and 11.6 million shares of Denbury common stock, for a total aggregate value of $439 million. Conroe Field had estimated proved non-tertiary reserves of approximately 7.0 MMBOE at December 31, 2016, net to our interest, all of which are proved developed. During the fourth quarter of 2016, production at Conroe Field averaged 2,281 BOE/d, compared to 2,889 BOE/d in the fourth quarter of 2015. To initiate a CO2 flood at Conroe Field, a pipeline must be constructed so that CO2 can be delivered to the field. This pipeline, which is planned as an extension of our Green Pipeline, is preliminarily estimated to cover approximately 90 miles at a cost of approximately $220 million. Our current plan for initiating a CO2 flood at Conroe Field is scheduled several years from now, the timing of which may change depending on future oil prices and pipeline construction. 15 Denbury Resources Inc. Thompson Field. We acquired our interest in Thompson Field in June 2012 for $366 million. The field is located in Texas, approximately 18 miles west of our Hastings Field. Thompson Field had estimated proved non-tertiary reserves of approximately 4.0 MMBOE at December 31, 2016, net to our interest, all of which are proved developed. During the fourth quarter of 2016, non-tertiary production at Thompson Field averaged 1,344 BOE/d net to our interest, compared to 1,508 BOE/d in the fourth quarter of 2015. Thompson Field is geologically similar to Hastings Field, producing oil from the Frio zone at similar depths, and we therefore believe it has CO2 EOR potential. Under the terms of the Thompson Field acquisition agreement, after the initiation of CO2 injection, the seller will retain approximately a 5% gross revenue interest (less severance taxes) once average monthly oil production exceeds 3,000 Bbls/d. The timing of CO2 injections at Thompson Field is primarily dependent upon future oil prices. Rocky Mountain Region CO2 Sources and Pipelines LaBarge Field. We acquired an overriding royalty interest equivalent to an approximate one-third ownership interest in ExxonMobil’s CO2 reserves in LaBarge Field in the fourth quarter of 2012 as part of the sale and exchange transaction with ExxonMobil. Our interest at Riley Ridge (discussed below) is also produced from the LaBarge Field. LaBarge Field is located in southwestern Wyoming. During 2016, we received an average of approximately 63 MMcf/d of CO2 from ExxonMobil’s Shute Creek gas processing plant at LaBarge Field. Based on current capacity, and subject to availability of CO2, we currently expect that we could receive up to 115 MMcf/d of CO2 by 2021 from such plant. We pay ExxonMobil a fee to process and deliver the CO2, which we use in our Rocky Mountain region CO2 floods. As of December 31, 2016, our interest in LaBarge Field consisted of approximately 1.2 Tcf of proved CO2 reserves. Riley Ridge. The Riley Ridge Federal Unit is also located in southwestern Wyoming and produces gas from the same LaBarge Field. We own 100% of the operating interests in Riley Ridge, as well as a gas processing facility. We acquired the Riley Ridge Federal Unit and the associated gas processing facility with the intent to separate for sale the natural gas and helium from the full well stream after construction of the gas processing facility was completed, and ultimately for the purpose of gaining a source of CO2 to utilize in flooding our fields in the Rocky Mountain region. Subsequently, issues arose related to contractor performance and design failure that caused significant delays and incremental costs to complete the facility. We placed the gas processing facility into service during the fourth quarter of 2013, and we were successful in running the facility for part of 2014 before additional issues arose related to optimal operation of the facility and sulfur build-up in the gas supply wells. In mid-2014, the gas processing facility was shut-in and to date remains shut-in. We plan to continue engineering work and analysis in 2017 to determine if there are alternative options to remediate the sulfur build-up in the gas supply wells and to assess our ability to reduce the costs thereof; however, the time of completion and results of such analysis are currently uncertain. Other Rocky Mountain CO2 Sources. While Riley Ridge is a potential source of CO2 for flooding our fields in the Rocky Mountain region, we have formed alternative plans to develop our future CO2 EOR floods, which CO2 volumes we currently anticipate could be supplied through existing CO2 sources. We began purchasing and receiving CO2 from the ConocoPhillips-operated Lost Cabin gas plant in central Wyoming in the first quarter of 2013, under a contract that provides us as much as 50 MMcf/d of CO2 for use in our Rocky Mountain region CO2 floods. Greencore Pipeline. The 20-inch Greencore Pipeline in Wyoming is the first CO2 pipeline we constructed in the Rocky Mountain region. We plan to use the pipeline as our trunk line in the Rocky Mountain region, eventually connecting our various Rocky Mountain region CO2 sources (see Rocky Mountain Region CO2 Sources and Pipelines above) to the Cedar Creek Anticline in eastern Montana and western North Dakota. The initial 232-mile section of the Greencore Pipeline begins at the ConocoPhillips-operated Lost Cabin gas plant in Wyoming and terminates at Bell Creek Field in Montana. We completed construction of this section of the pipeline in the fourth quarter of 2012 and received our first CO2 deliveries from the ConocoPhillips-operated Lost Cabin gas plant during the first quarter of 2013. During the first quarter of 2014, we completed construction of an interconnect between our Greencore Pipeline and an existing third-party CO2 pipeline in Wyoming, which enables us to transport CO2 from LaBarge Field to our Bell Creek Field. 16 Tertiary Properties with Tertiary Production and Proved Tertiary Reserves at December 31, 2016 Denbury Resources Inc. Bell Creek Field. We acquired our interest in Bell Creek Field in southeast Montana as part of the Encore merger in 2010. The oil-producing reservoir in Bell Creek Field is a sandstone reservoir with characteristics similar to those we have successfully flooded with CO2 in the Gulf Coast region. During 2013, we began first CO2 injections into Bell Creek Field, recorded our first tertiary oil production, and booked initial proved tertiary reserves. Tertiary production, net to our interest, during the fourth quarter of 2016 averaged 3,269 Bbls/d of oil, compared to 2,806 Bbls/d in the fourth quarter of 2015, as production has steadily grown from the initial production response in the third quarter of 2013. Our 2017 development capital budget includes investing approximately $25 million in this field primarily related to expansion of the flood into new phases. We expect production from this field will continue to increase during 2017. Future Tertiary Properties with No Tertiary Production or Proved Tertiary Reserves at December 31, 2016 Cedar Creek Anticline. CCA is the largest potential EOR property that we own and currently our largest producing property, contributing approximately 26% of our 2016 total production. The field is primarily located in Montana but covers such a large area (approximately 126 miles) that it also extends into North Dakota. CCA is a series of 14 different operating areas, each of which could be considered a field by itself. We acquired our initial interest in CCA as part of the Encore merger in 2010 and acquired additional interests (the “CCA Acquisition”) from a wholly-owned subsidiary of ConocoPhillips in the first quarter of 2013 for $1.0 billion, adding 42.2 MMBOE of incremental proved reserves at that date. Production from CCA, net to our interest, averaged 15,186 BOE/d during the fourth quarter of 2016, compared to production during the fourth quarter of 2015 of 17,875 BOE/d. The non-tertiary proved reserves associated with CCA were 80.7 MMBOE, net to our interest, as of December 31, 2016. CCA is located approximately 110 miles north of Bell Creek Field, and we currently expect to ultimately connect this field to our Greencore Pipeline. In the future, we plan to perform minor conformance work at the field to minimize production declines, the timing of which will depend on future oil prices. Our current plan for initiating a CO2 flood at CCA is scheduled several years from now, the timing of which may change depending on future oil prices, pipeline permitting and sources and availability of CO2. In addition to the future plans to flood CCA with CO2, we are also creating plans for exploitation opportunities that exist across the field. Our 2017 development capital budget includes investing approximately $25 million in this field primarily related to field infrastructure upgrades. Grieve Field. In the second quarter of 2011, we entered into a farm-in agreement, under which we obtained a 65% working interest in Grieve Field, located in Natrona County, Wyoming, in exchange for developing the Grieve Field CO2 flood. We completed a three-mile CO2 pipeline to deliver CO2 from an existing CO2 pipeline to Grieve Field in the fourth quarter of 2012. During the third quarter of 2016, the Company and its joint venture partner in Grieve Field reached an agreement to revise the joint venture arrangement between the parties for the continued development of the field. The revised agreement provides for our partner to fund up to $55 million of the remaining estimated capital to complete development of the facility and fieldwork in exchange for a 14% higher working interest and a disproportionate sharing of revenue from the first 2 million barrels of production. As a result of this agreement, our working interest in the field was reduced from 65% to 51%. This arrangement will accelerate the remaining development of the facility and fieldwork, and we currently anticipate first tertiary production by the middle of 2018. Hartzog Draw Field. We acquired our interest in Hartzog Draw Field in the fourth quarter of 2012. The field is located in the Powder River Basin of northeastern Wyoming, approximately 12 miles from our Greencore Pipeline. Hartzog Draw Field had estimated proved reserves of approximately 3.2 MMBOE at December 31, 2016, net to our interest, 1.0 MMBOE of which relate to the natural gas producing Big George coal zone. During the fourth quarter of 2016, non-tertiary production averaged 1,665 BOE/d, compared to 2,212 BOE/d in the fourth quarter of 2015. We successfully completed 5 wells in Hartzog Draw Field in 2014; however, we have temporarily suspended the non-tertiary development of Hartzog Draw Field in light of the recent oil price environment. We believe the oil reservoir characteristics of Hartzog Draw Field make it well suited for CO2 EOR in the future. We currently plan to initiate a CO2 flood at Hartzog Draw Field several years from now, the timing of which is dependent on future oil prices. 17 Other Non-Tertiary Oil Properties Denbury Resources Inc. Despite the majority of our oil and natural gas properties discussed above consisting of either existing or planned future tertiary floods, we do also produce oil and natural gas either from fields in both our Gulf Coast and Rocky Mountain regions that are not amenable to EOR or from specific reservoirs (within an existing tertiary field) that are not amenable to EOR. For example, at Heidelberg Field, we produce natural gas from the Selma Chalk reservoir, which is separate from the Christmas and Eutaw reservoirs currently being flooded with CO2. Continuing production from these other non-tertiary properties totaled 2,035 BOE/d during the fourth quarter of 2016, compared to 3,444 BOE/d during the fourth quarter of 2015. OIL AND GAS ACREAGE, PRODUCTIVE WELLS AND DRILLING ACTIVITY In the data below, “gross” represents the total acres or wells in which we own a working interest and “net” represents the gross acres or wells multiplied by our working interest percentage. For the wells that produce both oil and gas, the well is typically classified as an oil or natural gas well based on the ratio of oil to natural gas production. Oil and Gas Acreage The following table sets forth our acreage position at December 31, 2016: Gulf Coast region Rocky Mountain region Total Developed Undeveloped Total Gross 245,869 324,489 570,358 Net 199,089 298,336 497,425 Gross 284,606 190,129 474,735 Net 16,712 75,041 91,753 Gross 530,475 514,618 1,045,093 Net 215,801 373,377 589,178 The percentage of our net undeveloped acreage that is subject to expiration over the next three years, if not renewed, is approximately 2% in 2017, 11% in 2018 and 25% in 2019. Productive Wells The following table sets forth our gross and net productive oil and natural gas wells as of December 31, 2016: Producing Oil Wells Producing Natural Gas Wells Total Gross Net Gross Net Gross Net Operated wells Gulf Coast region Rocky Mountain region Total Non-operated wells Gulf Coast region Rocky Mountain region Total Total wells Gulf Coast region Rocky Mountain region Total 1,262 945 2,207 38 22 60 1,300 967 2,267 1,174 898 2,072 2 5 7 1,176 903 2,079 18 161 281 442 — 3 3 161 284 445 149 144 293 — 1 1 149 145 294 1,423 1,226 2,649 38 25 63 1,461 1,251 2,712 1,323 1,042 2,365 2 6 8 1,325 1,048 2,373 Drilling Activity Denbury Resources Inc.

Generally, an exploratory well is any well that is not a development well, an extension well, a service well or a stratigraphic test well. A development well is a well drilled within the proved area of an oil or gas reservoir to the depth of a stratigraphic horizon known to be productive. (2) A productive well is an exploratory or development well found to be capable of producing either oil or natural gas in sufficient quantities to justify completion as an oil or natural gas well. (3) A non-productive well is an exploratory or development well that is not a productive well. (4) During 2016, 2015 and 2014, an additional 1, 6 and 43 wells, respectively, were drilled for water or CO2 injection purposes. 19 The following table summarizes sales volumes, sales prices and production cost information for our net oil and natural gas production for the years ended December 31, 2016, 2015 and 2014: Denbury Resources Inc.

If these amounts were excluded, average production costs per BOE for the Gulf Coast region would have totaled $20.29 and $25.31 for the years ended December 31, 2015 and 2014, respectively, and average production costs per BOE for the Company as a whole would have totaled $19.88 and $24.10 for the years ended December 31, 2015 and 2014, respectively. PRODUCTION AND UNIT PRICES Further information regarding average production rates, unit sales prices and unit costs per BOE are set forth under Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations – Operating Results Table, included herein. 20 TITLE TO PROPERTIES Denbury Resources Inc. As is customary in the oil and natural gas industry, Denbury conducts a limited title examination at the time of its acquisition of properties or leasehold interests targeted for enhanced recovery, and curative work is performed with respect to significant defects on higher-value properties of the greatest significance. We believe that title to our oil and natural gas properties is good and defensible, subject only to such exceptions that we believe do not materially interfere with the use of such properties, including encumbrances, easements, restrictions and royalty, overriding royalty and other similar interests. SIGNIFICANT OIL AND GAS PURCHASERS AND PRODUCT MARKETING Oil and natural gas sales are made on a day-to-day basis or under short-term contracts at the current area market price. We would not expect the loss of any single purchaser to have a material adverse effect upon our operations; however, the loss of a large single purchaser could potentially reduce the competition for our oil and natural gas production, which in turn could negatively impact the prices we receive. For the year ended December 31, 2016, two purchasers accounted for 10% or more of our oil and natural gas revenues: Plains Marketing LP (20%) and Marathon Petroleum Company (14%). For the year ended December 31, 2015, two purchasers accounted for 10% or more of our oil and natural gas revenues: Marathon Petroleum Company (28%) and Plains Marketing LP (15%). For the year ended December 31, 2014, three purchasers accounted for 10% or more of our oil and natural gas revenues: Marathon Petroleum Company (31%), Plains Marketing LP (13%), and ConocoPhillips (12%). Our ability to market oil and natural gas depends on many factors beyond our control, including the extent of domestic production and imports of oil and natural gas, the proximity of our oil and natural gas production to pipelines and corresponding markets, the available capacity in such pipelines, the demand for oil and natural gas, the effects of weather, and the effects of state and federal regulation. As of December 31, 2016, we have not experienced significant difficulty in finding a market for all of our production as it becomes available or in transporting our production to those markets; however, there is no assurance that we will always be able to market all of our production or obtain favorable prices. Oil Marketing Prices received in a regional market fluctuate frequently and can differ from NYMEX pricing due to a variety of reasons, including supply and/or demand factors, crude oil quality and location differentials. The oil differentials we received in the Gulf Coast and Rocky Mountain regions are discussed in further detail below. Crude oil prices in the Gulf Coast region are impacted significantly by the changes in prices received for our crude oil sold under Light Louisiana Sweet (“LLS”) index prices relative to the change in NYMEX prices. Overall, during 2016, we sold approximately 60% of our crude oil at prices based on, or partially tied to, the LLS index price, and the balance at prices based on various other indexes tied to NYMEX prices, primarily in the Rocky Mountain region. The average LLS-to-NYMEX differential (on a trade-month basis) was a positive $1.70 per Bbl during 2016, compared to a positive $3.72 per Bbl during 2015 and a positive $3.88 per Bbl in 2014. During 2016, our light sweet crude oil production in the Gulf Coast region, on average, sold for $1.38 per Bbl below NYMEX, compared to $0.56 per Bbl over NYMEX in 2015 and $1.80 per Bbl over NYMEX in 2014. Our current markets at various sales points along the Gulf Coast have sufficient demand to accommodate our production, but there can be no assurance of future demand. We are, therefore, monitoring the marketplace for opportunities to strategically enter into long-term marketing arrangements. The marketing of our Rocky Mountain region oil production is dependent on transportation through local pipelines to market centers in Guernsey, Wyoming; Clearbrook, Minnesota; Wood River, Illinois; and most recently Cushing, Oklahoma. Shipments on some of the pipelines are at or near capacity and may be subject to apportionment. We currently have access to, or have contracted for, sufficient pipeline capacity to move our oil production; however, there can be no assurance that we will be allocated sufficient pipeline capacity to move all of our oil production in the future. Because local demand for production is small in comparison to current production levels, much of the production in the Rocky Mountain region is transported to markets outside of the region. Therefore, prices in the Rocky Mountain region are further influenced by fluctuations in prices (primarily Brent and LLS) in coastal markets and by available pipeline capacity in the Midwest and Cushing markets. For the year ended December 31, 2016, the discount for our oil production in the Rocky Mountain region averaged $3.97 per Bbl, compared to $5.60 per Bbl during 2015 and $10.19 per Bbl during 2014. 21 Natural Gas Marketing Denbury Resources Inc. We have minimal natural gas production, as 96% of our 2016 average daily production was oil. Virtually all of our natural gas production in the Gulf Coast region is close to existing pipelines; consequently, we generally have a variety of options to market our natural gas. However, our natural gas production in the Rocky Mountain region, like our oil production, is dependent on, among other factors, limited transportation options that can affect our ability to find markets for it. We sell the majority of our natural gas on one-year contracts, with prices fluctuating month to month based on published pipeline indices and with slight premiums or discounts to the index. COMPETITION AND MARKETS We face competition from other oil and natural gas companies in all aspects of our business, including acquisition of producing properties, oil and gas leases, drilling rights, and CO2 properties; marketing of oil and natural gas; and obtaining and maintaining goods, services and labor. Many of our competitors have substantially larger financial and other resources. Factors that affect our ability to acquire producing properties include available liquidity, available information about prospective properties and our expectations for earning a minimum projected return on our investments. Because of the primary nature of our core assets (our tertiary operations) and our ownership of relatively uncommon significant natural sources of CO2 in the Gulf Coast and Rocky Mountain regions, we believe that we are effective in competing in the market and have less competition than our peers in certain aspects of our business. The demand for qualified and experienced field personnel to drill wells and conduct field operations and for geologists, geophysicists, engineers and other professionals in the oil and gas industry can fluctuate significantly, often in correlation with commodity prices, causing periodic shortages in such personnel. Prior to the recent downturn in oil prices, the competition for qualified technical personnel had been extensive, and our personnel costs escalated. There were also periods with shortages of drilling rigs and other equipment, as demand for rigs and equipment has increased along with the number of wells being drilled. These factors also cause significant increases in costs for equipment, services and personnel. We cannot be certain when we will experience these issues, and these types of shortages or price increases could significantly decrease our profit margin, cash flow and operating results, and cause significant delays in our development operations. FEDERAL AND STATE REGULATIONS Numerous federal, state and local laws and regulations govern the oil and gas industry. Additions or changes to these laws and regulations are often made in response to the current political or economic environment. Compliance with the evolving regulatory landscape is often difficult, and substantial penalties may be incurred for noncompliance. Additionally, the future annual cost of complying with all laws and regulations applicable to our operations is uncertain and will be ultimately determined by several factors, including future changes to legal and regulatory requirements. Management believes that continued compliance with existing laws and regulations applicable to our operations and future compliance therewith will not have a materially adverse effect on our consolidated financial position, results of operations or cash flows, although such laws and regulations, and compliance therewith, could cause significant delays or otherwise impede operations, which may, among other things, cause our expected production rates and cash flows to be less than anticipated. The following sections describe some specific laws and regulations that may affect us. We cannot predict the cost or impact of these or other future legislative or regulatory initiatives. Regulation of Natural Gas and Oil Exploration and Production Our operations are subject to various types of regulation at the federal, state and local levels. Such regulation includes requiring permits for drilling wells; maintaining bonding requirements in order to drill or operate wells and regulating the location of wells; the method of drilling and casing wells; the surface use and restoration of properties upon which wells are drilled; the plugging and abandoning of wells; and the composition or disposal of chemicals and fluids used in connection with operations. Our operations are also subject to various conservation laws and regulations. These include regulation of the size of drilling, spacing or proration units and the density of wells that may be drilled in those units, and the unitization or pooling of oil and gas properties. In addition, federal and state conservation laws, which establish maximum rates of production from oil and gas wells, generally prohibit or restrict the venting or flaring of natural gas and impose certain requirements regarding the ratability of production. The effect of these laws and regulations may limit the amount of oil and 22 Denbury Resources Inc. natural gas we can produce from our wells and may limit the number of wells or the locations at which we can drill. Regulatory requirements and compliance relative to the oil and gas industry increase our costs of doing business and, consequently, affect our profitability. Federal Regulation of Sales Prices and Transportation The transportation of, and certain sales with respect to, natural gas in interstate commerce are heavily regulated by agencies of the U.S. federal government and are affected by, among other things, the availability, terms and cost of transportation. Notably, the price and terms of access to pipeline transportation are subject to extensive U.S. federal and state regulation. The Federal Energy Regulatory Commission (“FERC”) is continually proposing and implementing new and/or modified rules and regulations affecting the natural gas industry, some of which may adversely affect the availability and reliability of interruptible transportation service on interstate pipelines. While our sales of crude oil, condensate and natural gas liquids are not currently subject to FERC regulation, our ability to transport and sell such products is dependent on certain pipelines whose rates, terms and conditions of service are subject to FERC regulation. Additional proposals and proceedings that might affect the natural gas industry are considered from time to time by Congress, FERC, state regulatory bodies and the courts, and we cannot predict when or if any such proposals or proceedings might become effective and their effect or impact, if any, on our operations. Federal Energy and Climate Change Legislation and Regulation The Pipeline Safety, Regulatory Certainty and Job Creation Act of 2011, among other things, updated federal pipeline safety standards, increased penalties for violations of such standards, gave the Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (the “PHMSA”) authority for new damage prevention and incident notification, and directed the PHMSA to prescribe new minimum safety standards for CO2 pipelines, which safety standards could affect our operations and the costs thereof. While the PHMSA has adopted or proposed to adopt a number of new regulations to implement this act, no new minimum safety standards have been proposed or adopted for CO2 pipelines. Both federal and state authorities have in recent years proposed new regulations to limit the emission of greenhouse gasses as part of climate change initiatives. For example, both the EPA and BLM have issued regulations for the control of methane emissions. The EPA has promulgated regulations requiring permitting for certain sources of greenhouse gas emissions, and in May 2016, promulgated final regulations to reduce methane and volatile organic compound emissions from the oil and gas sector. Enforcement of these regulations may impose additional costs related to compliance with new emission limits, as well as inspections and maintenance of several types of equipment used in our operations. Conversely, on February 3, 2017, the U.S. House of Representatives approved a resolution to void a Bureau of Land Management rule restricting methane venting and flaring, which must be approved by the U.S. Senate and signed by the President to take effect. Natural Gas Gathering Regulations State and federal regulation of natural gas gathering facilities generally includes various safety, environmental and, in some circumstances, nondiscriminatory-take requirements. With the increase in construction and operation of natural gas gathering lines in various states, natural gas gathering is receiving greater regulatory scrutiny from state and federal regulatory agencies, which is likely to continue in the future. Federal, State or Indian Leases Our operations on federal, state or Indian oil and gas leases, especially those in the Rocky Mountain region, are subject to numerous restrictions, including nondiscrimination statutes. Such operations must be conducted pursuant to certain on- site security regulations and other permits and authorizations issued by the Bureau of Land Management, the Bureau of Ocean Energy Management, the Bureau of Safety and Environmental Enforcement, the Bureau of Indian Affairs, and other federal and state stakeholder agencies. Environmental Regulations Our oil and natural gas production, saltwater disposal operations, injection of CO2, and the processing, handling and disposal of materials such as hydrocarbons and naturally occurring radioactive materials (“NORM”) are subject to stringent 23 Denbury Resources Inc. regulation. We could incur significant costs, including cleanup costs resulting from a release of product, third-party claims for property damage and personal injuries, or penalties and other sanctions as a result of any violations or liabilities under environmental laws and regulations or other laws and regulations applicable to our operations. Changes in, or more stringent enforcement of, environmental laws and other laws applicable to our operations could also result in delays or additional operating costs and capital expenditures. Various federal, state and local laws and regulations controlling the discharge of materials into the environment, or otherwise relating to the protection of the environment and human health, directly impact our oil and gas exploration, development and production operations. These include, among others, (1) regulations adopted by the EPA and various state agencies regarding approved methods of disposal for certain hazardous and nonhazardous wastes; (2) the Comprehensive Environmental Response, Compensation, and Liability Act and analogous state laws that regulate the removal or remediation of previously disposed wastes (including wastes disposed of or released by prior owners or operators), property contamination (including groundwater contamination), and remedial plugging operations to prevent future contamination; (3) the Clean Air Act and comparable state and local requirements already applicable to our operations and new restrictions on air emissions from our operations, including greenhouse gas emissions and those that could discourage the production of fossil fuels that, when used, ultimately release CO2; (4) the Oil Pollution Act of 1990, which contains numerous requirements relating to the prevention of, and response to, oil spills into waters of the United States; (5) the Resource Conservation and Recovery Act, which is the principal federal statute governing the treatment, storage and disposal of hazardous wastes; (6) the Endangered Species Act and counterpart state legislation, which protects certain species (and their related habitats), including certain species that could be present on our leases, as threatened or endangered; and (7) state regulations and statutes governing the handling, treatment, storage and disposal of NORM and other wastes. In the Rocky Mountain Region, federal agencies’ actions based upon their environmental review responsibilities under the National Environmental Policy Act can significantly impact the scope and timing of hydrocarbon development by slowing the timing of individual applications for permits to drill and requests for rights-of-way, and delaying large scale planning associated with region-level resource management plans and project-level master development plans. Given the Trump administration’s announced intention to revise or rescind federal regulations promulgated during the Obama administration and to promote fossil fuel development on federal lands, it is possible that there could be an increase in litigation initiated by environmental or citizens groups, state attorneys general, or other elected or appointed officials. Management believes that we are currently in substantial compliance with existing applicable environmental laws and regulations, and does not currently anticipate that future compliance will have a materially adverse effect on our consolidated financial position, results of operations or cash flows, although such laws and regulations, and compliance therewith, could cause significant delays or otherwise impede operations, which may, among other things, cause our expected production rates and cash flows to be less than anticipated. Hydraulic Fracturing During 2016, we fracture stimulated one water source well at Tinsley Field utilizing water-based fluids with no diesel fuel component. We are currently evaluating the potential to refrac approximately five wells at Hartzog Draw Field during 2017. We are familiar with the laws and regulations applicable to hydraulic fracturing operations and take steps to ensure compliance with these requirements. 24 Item 1A. Risk Factors Denbury Resources Inc. Oil and natural gas prices are volatile. A sustained period of deterioration of oil prices is likely to adversely affect our future financial condition, results of operations, cash flows and the carrying value of our oil and natural gas properties. Oil prices have historically been volatile, with NYMEX oil prices ranging from $26 to $107 per Bbl over the last three calendar years, with prices in February 2016 representing the lowest level in over 14 years. Even if oil prices recover for a period of time, volatility will remain, and prices could move downward or upward on a rapid or repeated basis, which can make transactions, valuations and business strategies difficult. Our cash flow from operations is highly dependent on the prices that we receive for oil, as oil comprised approximately 96% of our 2016 production and approximately 97% of our proved reserves at December 31, 2016. The prices for oil and natural gas are subject to a variety of factors that are beyond our control. These factors include the supply of, and demand for, these commodities, which fluctuate with changes in market and economic conditions and other factors, including: • • the level of worldwide consumer demand for oil and natural gas and the domestic and foreign supply of oil and natural gas and levels of domestic oil and gas storage; the degree to which members of the Organization of Petroleum Exporting Countries maintain oil price and production controls; • the degree to which domestic oil and natural gas production affects worldwide supply of crude oil or its price; • worldwide political events, conditions and policies, including actions taken by foreign oil and natural gas producing nations; and • worldwide economic conditions. Due to the sustained period of low oil prices, the PV-10 Value of our estimated proved reserves was less than our outstanding indebtedness as of December 31, 2016. If oil prices decline further for an extended period of time, we could be harmed in a number of ways, including: • • • lower cash flows from operations may require continued or further reduced levels of capital expenditures; reduced levels of capital expenditures in turn could lower our present and future production levels, and lower the quantities and value of our oil and gas reserves, which constitute our major asset; our lenders could reduce our borrowing base, and we may not be able to raise capital at attractive rates in the public markets; • we could be forced to increase our level of indebtedness, issue additional equity, or sell assets; • we could have difficulty repaying or refinancing our indebtedness; • we could be required to impair various assets, including a further write-down of our oil and natural gas assets or the • • value of other tangible or intangible assets; construction of plants that produce CO2 as a byproduct that we can purchase could be delayed or cancelled, thus limiting the amount of industrial-source CO2 available for use in our tertiary operations; and/or our potential cash flows from our commodity derivative contracts that include sold puts could be limited to the extent that oil prices are below the prices of those sold puts. Furthermore, some or all of our tertiary projects could remain or become uneconomical. We may also decide to suspend future expansion projects, and if prices were to drop below our operating cash break-even points for an extended period of time, we may further decide to shut-in existing production, both of which could have a material adverse effect on our operations, financial condition and reduce our production. A financial downturn in one or more of the world’s major markets could negatively affect our liquidity, business and financial condition. Liquidity is essential to our business. Our liquidity could be substantially negatively affected by an inability to obtain capital in the long-term or short-term debt capital markets or equity capital markets or an inability to access bank financing. A sustained credit crisis, further drops in economic growth rates in China, regional or worldwide increases in tariffs or other trade restrictions, significant international currency fluctuations, a severe economic contraction either regionally or worldwide or turmoil in the global financial system, could materially affect our liquidity, business and financial condition. In the past, conditions such as these have adversely impacted financial markets and have created substantial volatility and uncertainty 25 Denbury Resources Inc. with the related negative impact on global economic activity. Negative credit market conditions could inhibit our lenders from fully funding our bank credit facility or cause them to make the terms of our bank credit facility more costly and more restrictive. Negative economic conditions could also adversely affect the collectability of our trade receivables or performance by our suppliers or cause our commodity hedging arrangements to be ineffective if our counterparties are unable to perform their obligations or otherwise seek bankruptcy protection. Our level of indebtedness could adversely affect the level of our production activities if not materially reduced. As of December 31, 2016, our outstanding indebtedness consisted of $614.9 million principal amount of 9% Senior Secured Second Lien Notes due 2021, $1.6 billion principal amount of subordinated notes, virtually all of which have maturity dates between 2021 and 2023 at interest rates ranging from 4.625% to 6.375% per annum at a weighted average interest rate of 5.28% per annum, and $301.0 million principal amount outstanding under our bank credit facility. As of February 22, 2017, we have a borrowing base and aggregate lender commitments of $1.05 billion under our bank credit facility and availability with respect to such commitments of $674.7 million. Our bank borrowing base is adjusted semiannually in May and November of each year, and upon requested unscheduled special redeterminations, in each case at the banks’ discretion, and the amount is established and based, in part, upon certain external factors, such as commodity prices. We do not know, nor can we control, the results of such redeterminations or the effect of then-current oil and natural gas prices on any such redetermination. A future redetermination lowering our borrowing base could limit availability under our bank credit facility. If the outstanding debt under our bank credit facility were to ever exceed the borrowing base, we would be required to repay the excess amount over a period not to exceed six months. The level of our indebtedness could have important consequences, including but not limited to the following: • • • • • • • increasing our vulnerability to general adverse economic and industry conditions; impairing our ability to obtain additional financing for working capital, capital expenditures, acquisitions, development activities or general corporate and other purposes; potentially restricting us from making acquisitions or exploiting business opportunities; reducing our available cash flow if market interest rates increase or if the level of our indebtedness significantly increases; requiring dedication of a substantial portion of our cash flows from operations to servicing our indebtedness (so that such cash flows would not be available for capital expenditures or other purposes); limiting our ability to borrow additional funds, dispose of assets, pay dividends, fund share repurchases and make certain investments; and/or placing us at a competitive disadvantage as compared to our competitors that have less debt. Additionally, rising interest rates would, among other things, affect our interest costs under our bank credit facility, increase the cost of any new debt financings, or limit our ability to otherwise borrow additional funds on favorable terms. The debt covenants contained in the agreements governing our outstanding indebtedness may also affect our flexibility in reacting to changes in the economy and in our industry. For example, as our cash flow from operations is highly dependent on the prices that we receive for oil and natural gas, our leverage metrics deteriorated during 2015 and 2016. Between May 2015 and April 2016, we modified certain of our financial performance covenants under our senior secured bank credit facility applicable to the 2016, 2017 and 2018 periods to support continuing compliance with these covenants in this low oil price environment. If oil and natural gas prices remain at current levels for an extended period of time, these metrics could deteriorate further, potentially causing us to not be in compliance with our bank credit facility’s covenants. In the future, we may be required to seek further modifications of these covenants, or to further reduce our debt by, among other things, purchasing our subordinated debt in the open market, completing cash tenders for our debt or public or privately negotiated debt exchanges, issuing equity or completing asset sales and other cash-generating activities. We cannot assure you, however, that we will be able to successfully modify these covenants or reduce our debt in the future. For more information on our bank credit facility, see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Liquidity – Senior Secured Bank Credit Facility. 26 Denbury Resources Inc. Any failure to meet our debt obligations or comply with the debt covenants contained in the agreements governing our outstanding indebtedness could harm our business, financial condition and results of operations. We expect our cash flows to vary significantly from year to year due to the cyclical nature of our business. A sustained period of low oil prices or their further deterioration may cause us to be unable to make required payments on our indebtedness. If we are unable to generate sufficient cash flows or otherwise obtain funds necessary to make required payments on our indebtedness, or if we otherwise fail to comply with the various covenants governing such indebtedness, especially those in our bank credit facility, we could be in default under such indebtedness. Any such default, if not cured or waived, could permit the holders of such indebtedness to accelerate the maturity of such indebtedness and could cause defaults under other indebtedness, which could have a material adverse effect on us. In addition, any failure to make scheduled payments of interest and principal on our outstanding indebtedness would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness on acceptable terms. Our ability to meet our obligations under our debt instruments will depend, in part, upon our future performance, which will be subject to prevailing economic conditions, commodity prices, and financial, business and other factors, including factors beyond our control. A cyber incident could occur and result in information theft, data corruption, operational disruption, and/or financial loss. Our business has become increasingly dependent on digital technologies to conduct day-to-day operations, including certain of our exploration, development and production activities. We depend on digital technology, among other things, to estimate quantities of oil and natural gas reserves; process and record financial and operating data; analyze seismic and drilling information; process wire transfers and store our banking information; monitor and control pipeline and plant equipment; process and store personally identifiable information of our employees and royalty owners; and communicate with employees, stakeholders and business associates. Our technologies, systems and networks may become the target of cyber attacks or information security breaches that could result in the disruption of our business operations and/or financial loss. For example, unauthorized access to our seismic data, reserves information or other proprietary information could lead to data corruption, communication interruption, or other operational disruptions in our drilling or production operations. Although we utilize various procedures and controls to monitor and protect against these threats and to mitigate our exposure to such threats, there can be no assurance that these procedures and controls will be sufficient in preventing security threats from materializing and causing us to suffer such losses in the future. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our procedures and controls or to investigate and remediate any cyber vulnerabilities. Oil and natural gas development and producing operations involve various risks. Our operations are subject to all the risks normally incident and inherent to the operation and development of oil and natural gas properties and the drilling of oil and natural gas wells, including, without limitation, well blowouts; cratering and explosions; pipe failure; fires; formations with abnormal pressures; uncontrollable flows of oil, natural gas, brine or well fluids; release of contaminants into the environment and other environmental hazards and risks. In addition, our operations are sometimes near populated commercial or residential areas, which add additional risks. The nature of these risks is such that some liabilities could exceed our insurance policy limits or otherwise be excluded from, or limited by, our insurance coverage, as in the case of environmental fines and penalties, for example, which are excluded from coverage as they cannot be insured. We could incur significant costs related to these risks that could have a material adverse effect on our results of operations, financial condition and cash flows. If these costs were to increase significantly, it could have an adverse effect upon the profitability of these operations. Additionally, a portion of our production activities involves CO2 injections into fields with wells plugged and abandoned by prior operators. However, it is often difficult (or impracticable) to determine whether a well has been properly plugged prior to commencing injections and pressuring the oil reservoirs. We may incur significant costs in connection with remedial plugging operations to prevent environmental contamination and to otherwise comply with federal, state and local regulations relative to the plugging and abandoning of our oil, natural gas and CO2 wells. In addition to the increased costs, if wells have not been properly plugged, modification to those wells may delay our operations and reduce our production. 27 Denbury Resources Inc. Development activities are subject to many risks, including the risk that we will not recover all or any portion of our investment in such wells. Drilling for oil and natural gas may involve unprofitable efforts, not only from dry wells, but also from wells that are productive but do not produce sufficient net reserves to return a profit after deducting drilling, operating and other costs. The cost of drilling, completing and operating a well is often uncertain, and cost factors can adversely affect the economics of a project. Further, our drilling operations may be curtailed, delayed or canceled as a result of numerous factors, including: • • • • • • • unexpected drilling conditions; title problems; pressure or irregularities in formations; equipment failures or accidents; adverse weather conditions, including hurricanes and tropical storms in and around the Gulf of Mexico that can damage oil and natural gas facilities and delivery systems and disrupt operations, and winter conditions and forest fires in the Rocky Mountain region that can delay or impede operations; compliance with environmental and other governmental requirements; and the cost of, or shortages or delays in the availability of, drilling rigs, equipment, pipelines and services. Estimating our reserves, production and future net cash flows is difficult to do with any certainty. Estimating quantities of proved oil and natural gas reserves is a complex process. It requires interpretations of available technical data and various assumptions, including assumptions relating to economic factors such as future commodity prices, production costs, severance and excise taxes, capital expenditures and workover and remedial costs, and the assumed effect of governmental rules and regulations. There are numerous uncertainties about when a property may have proved reserves as compared to potential or probable reserves, particularly relating to our tertiary recovery operations. Forecasting the amount of oil reserves recoverable from tertiary operations, and the production rates anticipated therefrom, requires estimates, one of the most significant being the oil recovery factor. Actual results most likely will vary from our estimates. Also, the use of a 10% discount factor for reporting purposes, as prescribed by the SEC, may not necessarily represent the most appropriate discount factor, given actual interest rates and risks to which our business, and the oil and natural gas industry in general, are subject. Any significant inaccuracies in these interpretations or assumptions, or changes of conditions, could result in a revision of the quantities and net present value of our reserves. The reserves data included in documents incorporated by reference represent estimates only. Quantities of proved reserves are estimated based on economic conditions, including first-day-of-the-month average oil and natural gas prices for the 12- month period preceding the date of the assessment. The representative oil and natural gas prices used in estimating our December 31, 2016 reserves were $42.75 per Bbl for crude oil and $2.55 per MMBtu for natural gas, both of which were adjusted for market differentials by field. Rapid crude oil price declines beginning in late 2014 have resulted in a significant decrease in our proved reserve value, and to a lesser degree, a reduction in our proved reserve volumes, which has caused us to record write-downs due to the full cost ceiling test in 2015 and 2016. As discussed in greater detail below, further declines in oil prices could result in additional write-downs. Our reserves and future cash flows may be subject to revisions based upon changes in economic conditions, including oil and natural gas prices, as well as due to production results, results of future development, operating and development costs, and other factors. Downward revisions of our reserves could have an adverse effect on our financial condition and operating results. Actual future prices and costs may be materially higher or lower than the prices and costs used in our estimates. As of December 31, 2016, approximately 18% of our estimated proved reserves were undeveloped. Recovery of undeveloped reserves requires significant capital expenditures and may require successful drilling operations. The reserves data assumes that we can and will make these expenditures and conduct these operations successfully, but these assumptions may not be accurate, and these expenditures and operations may not occur. Our planned tertiary operations and the related construction of necessary CO2 pipelines could be delayed by difficulties in obtaining pipeline rights-of-way and/or permits, and/or by the listing of certain species as threatened or endangered. The production of crude oil from our planned tertiary operations is dependent upon having access to pipelines to transport available CO2 to our oil fields at a cost that is economically viable. Our current and future construction of CO2 pipelines will require us to obtain rights-of-way from private landowners, state and local governments and the federal government in certain 28 Denbury Resources Inc. areas. Certain states where we operate have considered or may again consider the adoption of laws or regulations that could limit or eliminate the ability of a pipeline owner or of a state, state’s legislature or its administrative agencies to exercise eminent domain over private property, in addition to possible judicially imposed constraints on, and additional requirements for, the exercise of eminent domain. We also conduct operations on federal and other oil and natural gas leases inhabited by species that could be listed as threatened or endangered under the Endangered Species Act, which listing could lead to tighter restrictions as to federal land use and other land use where federal approvals are required. These laws and regulations, together with any other changes in law related to the use of eminent domain or the listing of certain species as threatened or endangered, could inhibit or eliminate our ability to secure rights-of-way or otherwise access land for current or future pipeline construction projects. As a result, obtaining rights-of-way or other means of access may require additional regulatory and environmental compliance, and increased costs in connection therewith, which could delay our CO2 pipeline construction schedule and initiation of our pipeline operations, and/or increase the costs of constructing our pipelines. Pipeline projects are also subject to heightened levels of scrutiny as a result of public opposition to projects like the Keystone XL and Dakota Access pipelines. This scrutiny has the potential to result in permitting delays, enhanced and prolonged environmental review for pipeline projects, and litigation challenges to regulatory agencies’ authorizations of pipeline projects. Our future performance depends upon our ability to effectively develop our existing oil and natural gas reserves and find or acquire additional oil and natural gas reserves that are economically recoverable. Unless we can successfully develop our existing reserves and/or replace the reserves that we produce, our reserves will decline, resulting eventually in a decrease in oil and natural gas production and lower revenues and cash flows from operations. We have historically replaced reserves through both acquisitions and internal organic growth activities. For internal organic growth activities, the magnitude of proved reserves that we can book in any given year depends on our progress with new floods and the timing of the production response. In the future, we may not be able to continue to replace reserves at acceptable costs. The business of exploring for, developing or acquiring reserves is capital intensive. We may not be able to make the necessary capital investment to maintain or expand our oil and natural gas reserves if our cash flows from operations continue to be reduced, whether due to current oil or natural gas prices or otherwise, or if external sources of capital become limited or unavailable. Further, the process of using CO2 for tertiary recovery, and the related infrastructure, requires significant capital investment prior to any resulting and associated production and cash flows from these projects, heightening potential capital constraints. If capital expenditures remain at reduced levels, or if outside capital resources become limited, we will not be able to maintain our current production levels. We have acquired several fields at a substantial cost because we believe that they have significant additional production potential through tertiary flooding, and we may have the opportunity to acquire other oil fields that we believe are tertiary flood candidates, some of which may require significant amounts of capital. If we are unable to successfully develop and produce the potential oil in any acquired fields, it would negatively affect our return on investment relative to these acquisitions and could significantly reduce our ability to obtain additional capital for the future or fund future acquisitions, and also negatively affect our financial results to a significant degree. Commodity derivative contracts may expose us to potential financial loss. To reduce our exposure to fluctuations in the prices of oil and natural gas, we enter into commodity derivative contracts in order to economically hedge a portion of our forecasted oil and natural gas production. As of February 22, 2017, we have oil derivative contracts in place covering 39,000 Bbls/d for the first quarter of 2017, 29,000 Bbls/d for the second quarter of 2017, 16,500 Bbls/d for the third quarter of 2017, and 13,000 Bbls/d for the fourth quarter of 2017. Such derivative contracts expose us to risk of financial loss in some circumstances, including when there is a change in the expected differential between the underlying price in the hedging agreement and actual prices received, when the cash benefit from hedges including a sold put is limited to the extent oil prices fall below the price of our sold puts, or when the counterparty to the derivative contract is financially constrained and defaults on its contractual obligations. In addition, these derivative contracts may limit the benefit we would otherwise receive from increases in the prices for oil and natural gas. Shortages of or delays in the availability of oil field equipment, services and qualified personnel could reduce our cash flow and adversely affect results of operations. The demand for qualified and experienced field personnel, geologists, geophysicists, engineers and other professionals in the oil and natural gas industry can fluctuate significantly, often in correlation with oil and natural gas prices, causing 29 Denbury Resources Inc. periodic shortages in such personnel. In the past, during periods of high oil and natural gas prices, we have experienced shortages of oil field and other necessary equipment, including drilling rigs, along with increased prices for such equipment, services and associated personnel. These types of shortages or price increases could significantly decrease our profit margin, cash flow and operating results and/or restrict or delay our ability to drill wells and conduct our operations, possibly causing us to miss our forecasts and projections. The marketability of our production is dependent upon transportation lines and other facilities, certain of which we do not control. When these facilities are unavailable, our operations can be interrupted and our revenues reduced. The marketability of our oil and natural gas production depends, in part, upon the availability, proximity and capacity of transportation lines owned by third parties. In general, we do not control these transportation facilities, and our access to them may be limited or denied. A significant disruption in the availability of, and access to, these transportation lines or other production facilities could adversely impact our ability to deliver to market or produce our oil and thereby cause a significant interruption in our operations. Our production will decline if our access to sufficient amounts of carbon dioxide is limited. Our long-term strategy is primarily focused on our CO2 tertiary recovery operations. The crude oil production from our tertiary recovery projects depends, in large part, on having access to sufficient amounts of naturally occurring and industrial- sourced CO2. Our ability to produce oil from these projects would be hindered if our supply of CO2 was limited due to, among other things, problems with our current CO2 producing wells and facilities, including compression equipment, catastrophic pipeline failure or our ability to economically purchase CO2 from industrial sources. This could have a material adverse effect on our financial condition, results of operations and cash flows. Our anticipated future crude oil production from tertiary operations is also dependent on the timing, volumes and location of CO2 injections and, in particular, on our ability to increase our combined purchased and produced volumes of CO2 and inject adequate amounts of CO2 into the proper formation and area within each of our tertiary oil fields. The development of our naturally occurring CO2 sources involves the drilling of wells to increase and extend the CO2 reserves available for use in our tertiary fields. These drilling activities are subject to many of the same drilling and geological risks of drilling and producing oil and gas wells (see Oil and natural gas development and producing operations involve various risks above). Furthermore, recent market conditions may cause the delay or cancellation of construction of plants that produce industrial-source CO2 as a byproduct that we can purchase, thus limiting the amount of industrial-source CO2 available for our use in our tertiary operations. We may lose executive officers, key management personnel or other talented employees, which could endanger the future success of our operations. Our success depends to a significant degree upon the continued contributions of our executive officers and other key management personnel. Our employees, including our executive officers, are employed at will and do not have employment agreements. If one or more members of our management team dies, becomes disabled or voluntarily terminates employment with us, there is no assurance that we will find a suitable or comparable substitute. We believe that our future success depends, in large part, upon our ability to hire and retain highly skilled managerial personnel. Historically, a significant portion of the compensation paid to our executive officers and key management personnel has been through long-term grants of Company stock under our 2004 Omnibus Stock and Incentive Plan (the “2004 Plan”). If the shares reserved under the 2004 Plan are depleted and not replenished, we may be forced to eliminate long-term equity grants, which would negatively impact our ability to attract and retain highly skilled managerial personnel. Replacing long-term equity grants with cash compensation would reduce the cash available to fund capital expenditures. Additionally, in a low oil price environment, we could be susceptible to losing talented non-industry professionals (e.g., accountants, attorneys and human resources personnel). Competition for persons with these skills is intense, and there is no assurance that we will be successful in attracting and retaining such skilled and talented personnel. Governmental laws and regulations relating to environmental protection are costly and stringent. Our exploration, production, and marketing operations are subject to complex and stringent federal, state, and local laws and regulations governing, among other things, the discharge of substances into the environment or otherwise relating to the 30 Denbury Resources Inc. protection of human health and the environment, including the protection of endangered species. These laws and regulations and related public policy considerations affect the costs, manner, and feasibility of our operations and require us to make significant expenditures in order to comply. Failure to comply with these laws and regulations may result in the assessment of administrative, civil, and criminal penalties, the imposition of investigatory and remedial obligations, and the issuance of injunctions that could limit or prohibit our operations. In addition, some of these laws and regulations may impose joint and several, strict liability for contamination resulting from spills, discharges, and releases of substances, including petroleum hydrocarbons and other wastes, without regard to fault, or the legality of the original conduct. Under such laws and regulations, we could be required to remove or remediate previously disposed substances and property contamination, including wastes disposed or released by prior owners or operators. While the President has indicated that his administration will relax enforcement of and work to repeal certain federal environmental regulations that affect the oil and gas industry, we are currently unable to predict what, if any, changes will be made or their timing. Enactment of executive, legislative or regulatory proposals under consideration could negatively affect our business. Numerous executive, legislative and regulatory proposals affecting the oil and gas industry have been introduced, are anticipated to be introduced, or are otherwise under consideration, by the President, Congress, state legislatures and various federal and state agencies. While it is currently anticipated that the President and Congress will move away from the trend of proposing stricter standards and increasing oversight and regulation at the federal level, it is possible that other proposals affecting the oil and gas industry could be enacted or adopted in the future, which could result in increased costs or additional operating restrictions that could have an effect on demand for oil and natural gas or prices at which it can be sold. However, until such legislation or regulations are enacted or adopted into law and thereafter implemented, it is not possible to gauge their impact on our future operations or our results of operations and financial condition. The new Presidential administration and Congress have stated that comprehensive U.S. tax reform is a priority and have discussed their intent to pursue major federal tax reform. If major tax revisions are made, it is possible that a number of special tax provisions affecting the oil and gas industry could be changed. The passage of legislation or any other change in U.S. federal income tax law that eliminates, reduces or postpones certain tax deductions that are currently available to us or otherwise increases our taxes could negatively affect the after-tax returns generated on our oil and gas investments, our cash flow or our financial condition and results of operations, even if reduced corporate tax rates are enacted. The derivatives market regulations promulgated under the Dodd-Frank Act could have an adverse effect on our ability to hedge risks associated with our business. The Dodd-Frank Act requires the Commodities Futures Trading Commission and the SEC to promulgate rules and regulations establishing federal oversight and regulation of the over-the-counter derivatives market and entities that participate in that market, including swap clearing and trade execution requirements. Our derivative transactions are not currently subject to such swap clearing and trade execution requirements; however, in the event our derivative transactions potentially become subject to such requirements, we believe that our derivative transactions would qualify for the “end-user” exception. The Dodd-Frank Act, rules promulgated thereunder or new legislation or regulations, could (1) affect the cost, or decrease the liquidity, of energy-related derivatives available to us to hedge against commodity price fluctuations (including through requirements to post collateral), (2) materially alter the terms of derivative contracts, (3) affect the availability of derivatives to protect against risks we encounter, and (4) increase our exposure to less creditworthy counterparties. If we reduce our use of derivatives due to changes in the derivatives market, our cash flows could become more volatile and less predictable, which could adversely affect our ability to plan for and fund capital expenditures. On the other hand, there is significant uncertainty as to the status of the Dodd-Frank Act, and its regulations and enforcement, growing out of widespread discussion of repealing or scaling back the Dodd-Frank Act – either through legislative or regulatory action; however, it is not possible to determine at this time whether such changes will take place, in what form or to what extent. The loss of one or more of our large oil and natural gas purchasers could have an adverse effect on our operations. For the year ended December 31, 2016, two purchasers individually accounted for 10% or more of our oil and natural gas revenues and, in the aggregate, for 34% of such revenues. The loss of a large single purchaser could adversely impact the prices we receive or the transportation costs we incur. 31 Denbury Resources Inc. Certain of our operations may be limited during certain periods due to severe weather conditions and other regulations. Certain of our operations in North Dakota, Montana and Wyoming, including the construction of CO2 pipelines, the drilling of new wells and production from existing wells, are conducted in areas subject to extreme weather conditions, including severe cold, snow and rain, which conditions may cause such operations to be hindered or delayed, or otherwise require that they be conducted only during non-winter months, and depending on the severity of the weather, could have a negative effect on our results of operations in these areas. Further, certain of our operations in these areas are confined to certain time periods due to environmental regulations, federal restrictions on when drilling can take place on federal lands, and lease stipulations designed to protect certain wildlife, which regulations, restrictions and limitations could slow down our operations, cause delays, increase costs and have a negative effect on our results of operations. Our operations in the coastal areas of the Gulf Coast region may be subjected to adverse weather conditions such as hurricanes and tropical storms in and around the Gulf of Mexico that can damage oil and natural gas facilities and delivery systems and disrupt operations, which can also increase costs and have a negative effect on our results of operations. If commodity prices decline appreciably, we may be required to write down the carrying value of our oil and natural gas properties. Under full cost accounting rules related to our oil and natural gas properties, we are required each quarter to perform a ceiling test calculation, with the net capitalized costs of our oil and natural gas properties limited to the lower of unamortized cost or the cost center ceiling. The present value of estimated future net revenues from proved oil and natural gas reserves included in the cost center ceiling is based on the average first-day-of-the-month oil and natural gas price for each month during a 12-month rolling period prior to the end of a particular reporting period. During 2015 and 2016, we recorded full cost pool ceiling test write-downs of our oil and natural gas properties totaling $4.9 billion ($3.1 billion net of tax) and $810.9 million ($508.2 million net of tax), respectively (see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations – Write-Down of Oil and Natural Gas Properties and Critical Accounting Policies and Estimates – Full Cost Method of Accounting, Depletion and Depreciation and Oil and Natural Gas Properties). Future material write-downs of our oil and natural gas properties, as well as future impairment of other long-lived assets, could significantly reduce earnings during the period in which such write-down and/or impairment occurs and would result in a corresponding reduction to long-lived assets and equity. See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies and Estimates. Item 1B. Unresolved Staff Comments There are no unresolved written SEC staff comments regarding our periodic or current reports under the Securities Exchange Act of 1934 received 180 days or more before the end of the fiscal year to which this annual report on Form 10-K relates. Item 2. Properties Information regarding the Company’s properties called for by this item is included in Item 1, Business and Properties – Oil and Natural Gas Operations. We also have various operating leases for rental of office space, office and field equipment, and vehicles. See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Capital Resources and Liquidity – Off-Balance Sheet Arrangements, and Note 10, Commitments and Contingencies, to the Consolidated Financial Statements for the future minimum rental payments. Such information is incorporated herein by reference. Item 3. Legal Proceedings We are involved in various lawsuits, claims and regulatory proceedings incidental to our businesses. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our business or finances, litigation is subject to inherent uncertainties. Although a single or multiple adverse rulings or settlements could possibly have a material adverse effect on our business or finances, we only accrue for losses from litigation and claims if we determine that a loss is probable and the amount can be reasonably estimated. 32 Potential Mississippi Environmental Administrative Proceeding Denbury Resources Inc. For the past two years, the Company has been in negotiations with the Mississippi Department of Environmental Quality (“MDEQ”) that began following receipt of a February 2015 notice from the MDEQ related to a discharge of materials at the West Heidelberg Field in Jasper County, Mississippi in the third quarter of 2013. Based upon recent discussions with the MDEQ, it is currently anticipated that a settlement related to the discharge providing for a monetary fine as a civil penalty will be reached, thus eliminating the need for an administrative proceeding. The Company expects any such fine will not be material to the Company’s business or financial condition. Riley Ridge Helium Supply Contract Claim As part of our 2010 and 2011 acquisitions of the Riley Ridge Unit and associated gas processing facility that was under construction, we assumed a 20-year helium supply contract under which we agreed to supply to a third-party purchaser the helium separated from the full well stream by operation of the gas processing facility. The helium supply contract provides for the delivery of a minimum contracted quantity of helium, subject to adjustment after startup of the Riley Ridge gas processing facility, with liquidated damages payable if specified quantities of helium are not supplied in accordance with the terms of the contract. The liquidated damages are capped at $8.0 million per contract year and are capped at an aggregate of $46.0 million over the remaining term of the contract. As the gas processing facility has been shut-in since mid-2014, we have not been able to supply helium to the third-party purchaser under the helium supply contract. In a case originally filed in November 2014 by APMTG Helium, LLC, the third-party helium purchaser, in the Ninth Judicial District Court of Sublette County, Wyoming, after a week of trial on the third-party purchaser’s claim for multiple years of liquidated damages for non- delivery of volumes of helium specified under the helium supply contract, and on our claim that the contractual obligation is excused by virtue of events that fall within the force majeure provisions in the helium supply contract, the trial was stayed in late February 2017 until a later date yet to be determined by the District Court. The Company plans to continue to vigorously defend its position, but we are unable to predict at this time the outcome of this dispute. Item 4.

(1) Includes pre-tax impairments of assets of $810.9 million and $6.2 billion for the years ended December 31, 2016 and 2015, respectively, and an accelerated depreciation charge of $591.0 million related to the Riley Ridge gas processing facility and related assets for the year ended December 31, 2016. (2) In September 2015, in light of the continuing low oil price environment and our desire to maintain our financial strength and flexibility, the Company’s Board of Directors suspended our quarterly cash dividend. (3) Lease operating expenses reported in this table include certain special items comprised of (1) lease operating expenses and related insurance recoveries recorded to remediate an area of Delhi Field in 2014 and 2015, (2) a reimbursement for a retroactive utility rate adjustment in 2015, and (3) other insurance recoveries in 2015. If these special items are excluded, lease operating expenses would have totaled $528.8 million, $654.7 million and $616.6 million for the years ended December 31, 2015, 2014 and 2013, respectively, and lease operating expenses per BOE would have averaged $19.88, $24.10 and $24.05 for the years ended December 31, 2015, 2014 and 2013, respectively. (4) Depletion, depreciation, and amortization during the year ended December 31, 2016 includes an accelerated depreciation charge of $591.0 million, or $25.23 per BOE, associated with the Riley Ridge gas processing facility and related assets (see Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations – Results of Operations – Depletion, Depreciation, and Amortization). (5) Estimated proved reserves as of December 31, 2015, reflect negative reserve revisions of approximately 126 MMBOE (29%) in 2015 due to declines in the average first-day-of-the-month NYMEX oil price used to estimate reserves from $94.99 per Bbl at December 31, 2014, to $50.28 per Bbl at December 31, 2015. In addition, the average first-day-of- the-month NYMEX natural gas price used to estimate reserves declined from $4.30 per MMBtu at December 31, 2014, to $2.63 per MMBtu at December 31, 2015. (6) Proved CO2 reserves in the Gulf Coast region consist of reserves from our reservoirs at Jackson Dome and are presented on a gross or 8/8ths working interest basis, of which our net revenue interest was approximately 4.2 Tcf, 4.4 Tcf, 4.5 Tcf, 4.8 Tcf and 4.8 Tcf at December 31, 2016, 2015, 2014, 2013 and 2012, respectively, and include reserves dedicated to volumetric production payments of 12.3 Bcf, 25.3 Bcf, 9.3 Bcf, 28.9 Bcf and 57.1 Bcf at December 31, 2016, 2015, 2014, 2013 and 2012, respectively (see Supplemental CO2 Disclosures (Unaudited) to the Consolidated Financial Statements). (7) Proved CO2 reserves in the Rocky Mountain region consist of our overriding royalty interest in LaBarge Field and our reserves at Riley Ridge (presented on a gross (8/8ths) basis), of which our net revenue interest was approximately 1.2 Tcf, 1.2 Tcf, 2.6 Tcf, 2.9 Tcf and 2.9 Tcf at December 31, 2016, 2015, 2014, 2013 and 2012, respectively. As of December 31, 2015, Riley Ridge CO2 and helium reserves were reclassified and are no longer considered proved reserves primarily as a result of the decline in average first-day-of-the-month natural gas prices utilized in preparing our December 31, 2015 reserve report.

Item 7. Management’ g s Discussion and Analysis of Financial Condition and Results of Operations p y The following discussion and analysis should be read in conjunction with our Consolidated Financial Statements and Notes thereto included in Item 8, Financial Statements and Supplementary Information. Our discussion and analysis includes forward-looking information that involves risks and uncertainties and should be read in conjunction with Risk Factors under Item 1A of this Form 10-K, along with Forward-Looking Information at the end of this section for information on the risks and uncertainties that could cause our actual results to be materially different from our forward-looking statements. rr ff OVERVIEWRR Denbury is an independent oil and natural gas company with operations focused in two key operating areas: the Gulf Coast and Rocky Mountain regions. Our goal is to increase the value of our properties through a combination of exploitation, drilling and proven engineering extraction practices, with the most significant emphasis relating to CO2 enhanced oil recovery operations. Oil Price Decline and Impact on Our Business. Oil prices generally constitute the single largest variable in our operating results. Oil prices have historically been volatile, with NYMEX oil prices ranging from $26 to $107 per Bbl over the last three calendar years, with prices in February 2016 representing the lowest level in over 14 years. The following chart illustrates the fluctuations in our realized oil prices, excluding the impact of commodity derivative settlements, during 2014, 2015 and 2016. Average Realized Oil Price per Barrel l b B / $ $100 $90 $80 $70 $60 $50 $40 $30 $20 Three Months Ended Average realized prices First quarter Second quarter Third quarter Fourth quarter Oil price per Bbl 2014 2015 2016 $ 97.69 $ 46.02 $ 30.71 100.04 94.78 70.80 56.92 45.74 40.41 43.38 43.45 48.03 Although realized oil prices during the second half of 2016 increased from the lows experienced in the first quarter of 2016, our focus continues to remain on cost reductions and preserving liquidity. Cost reductions have been realized in 2016 in all categories of our business. Our 2016 capital development expenditures totaled $208.6 million, which were fully funded with cash flows from operations, thus preserving our liquidity. One advantage we have in this environment is that our oil assets have relatively low decline rates even with our significantly reduced planned capital spending level, and therefore our 38 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations average daily production declined by less than 10% in 2016, excluding the impact of weather-related downtime at Conroe and Thompson fields, completed asset sales, and production shut in for economic reasons. Lastly, we have hedged a portion of our estimated oil production through 2017 in order to cover our current level of cash operating costs and to help mitigate any future price declines or sustained low oil prices (see Results of Operations – Commodity Derivative Contracts below). Our 2017 capital spending has been budgeted at approximately $300 million, excluding capitalized interest and acquisitions, a 44% increase over the 2016 capital spending level. It is expected that the projected cash flow from operations, based on current NYMEX futures prices in late-February 2017, will fund all but a minor amount of this capital spending. With this increased capital spending level, we currently anticipate our 2017 average daily production remaining relatively flat with our exit rate in 2016 of roughly 60,000 BOE/d. During 2016, we have continued to evaluate our assets with a goal of increasing the value of both existing assets and future projects by optimizing field operational and development plans, reducing CO2 injection volumes through increased efficiency, and reducing costs such as power and workovers. We have reduced our overall CO2 injection volumes by 32% and our total lease operating expenses by $113.8 million (22%) on a normalized basis (see Results of Operations – Production Expenses – Lease Operating Expenses) when comparing the years ended December 31, 2016 and 2015. These initiatives aim to increase the profitability of our operations and make them more resilient to lower oil prices. 2016 Operating Highlights. Our financial results have been significantly impacted by the decrease in realized oil prices as highlighted above, which decreased from an average of $90.74 per Bbl during 2014 to $41.12 per Bbl during 2016. During 2016, we recognized a net loss of $976.2 million, compared to a net loss of $4.4 billion during 2015. Our net loss in 2016 decreased due to the substantial decrease in noncash impairments, primarily because oil prices, a significant driver of our full- cost ceiling test write-downs, stabilized and began to increase during the course of 2016, which resulted in the trailing 12- month average price (the primary driver of the value of our proved reserves and therefore any full cost pool ceiling test write- downs) flattening, rather than declining each quarter as was the case in 2015. Impairments of assets totaled $810.9 million ($508.2 million net of tax) in 2016, compared to $6.2 billion ($4.3 billion net of tax) in 2015 (see Results of Operations – Write-Down of Oil and Natural Gas Properties and 2015 Impairment of Goodwill below). Additionally, the effect of the reduction in asset impairments in 2016 was partially offset by an accelerated depreciation charge of $591.0 million recorded in 2016 related to the Riley Ridge gas processing facility and related assets (see Results of Operations – Depletion, Depreciation, and Amortization below). We generated $219.2 million of cash flow from operating activities during 2016, compared to $864.3 million during 2015, due primarily to a $427.5 million decline in derivative settlements and $277.3 million reduction in revenues due to the lower oil prices and less sales volumes, partially offset by reductions in operating expenses. During 2016, our oil and natural gas production, which was 96% oil, averaged 64,003 BOE/d, compared to an average of 72,861 BOE/d produced during 2015. This 12% decrease in production was primarily due to weather-related shut-in production, production shut in due to economics, facility downtime, maintenance and repair work, and natural production declines based on our lower capital spending level. Total production in 2015 also includes production related to certain non- core assets in the Williston Basin of North Dakota and Montana (the “Williston Assets”), which were sold during the third quarter of 2016, and other property divestitures. Production related to the Williston Assets and other property divestitures averaged 1,005 BOE/d in 2016, compared to 1,993 in 2015. These production decreases were partially offset by increases in production due to continued CO2 enhanced oil recovery response at Delhi Field in the Gulf Coast region and Bell Creek Field in the Rocky Mountain region. See Results of Operations – Production for further discussion. Our average realized oil price per barrel, excluding the impact of commodity derivative contracts, was $41.12 per Bbl during 2016, a decrease of 13% compared to $47.30 per Bbl realized during 2015. The oil price we realized relative to NYMEX oil prices (our NYMEX oil price differential) was $2.29 per Bbl below NYMEX prices during 2016, a $0.74 per Bbl decline compared to realized prices of $1.55 per Bbl below NYMEX in 2015, primarily due to weakening of our Gulf Coast region LLS price differentials, offset in part by improvement in the Rocky Mountain region discount in 2016 relative to NYMEX oil prices. One of our primary focuses in the past few years has been to reduce costs throughout the organization through a number of internal initiatives. As a result of these efforts, we have been able to achieve reductions in our lease operating expenses, with total lease operating expenses of $414.9 million during 2016, a 19% reduction when compared to 2015 levels. Excluding 39 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations special or unusual amounts reported in 2015, total lease operating expenses per BOE during 2016 were $17.71, compared to $19.88 during 2015, with decreases realized in most categories of lease operating expenses. General and administrative expenses per BOE decreased 14% when comparing the year-ended December 31, 2016 to 2015, primarily due to lower employee-related costs such as salaries, bonus accruals and long-term incentives. 2016 Debt Reduction Transactions. During 2016, we completed a series of privately negotiated debt exchanges and open-market debt repurchases, contributing to a net reduction of our debt principal balance of approximately $530.4 million between December 31, 2015 and 2016. In May 2016, we exchanged $1,057.8 million of existing senior subordinated notes with a limited number of holders for $614.9 million of our new 9% Senior Secured Second Lien Notes due 2021 (the “2021 Senior Secured Notes”) plus 40.7 million shares of Denbury common stock, resulting in a net reduction from these exchanges of $442.9 million in our debt principal. During 2016, we purchased $181.9 million of our existing senior subordinated notes for $76.7 million in open-market transactions, for a net reduction of $105.2 million of our debt principal. See Capital Resources and Liquidity – 2016 Debt Reduction Transactions for further discussion. 2016 Divestiture of Non-Core Assets. On August 31, 2016, we completed the sale of the Williston Assets for $58 million (before closing adjustments). The sale had an effective date of April 1, 2016, and proceeds realized after closing adjustments totaled $53.6 million. Approximately $9 million of proceeds from the sale of Williston Assets was paid by the purchaser directly to a qualified intermediary to facilitate a like-kind exchange, and are therefore not reflected as an investing activity in our Consolidated Statements of Cash Flows. Grieve Field Revised Joint Venture. On August 4, 2016, the Company and its joint venture partner in Grieve Field, located in Wyoming, reached an agreement to revise the joint venture arrangement between the parties for the continued development of such field. The revised agreement provides for our partner to fund up to $55 million of the remaining estimated capital to complete development of the facility and fieldwork in exchange for a 14% higher working interest and a disproportionate sharing of revenue from the first 2 million barrels of production. As a result of this agreement, our working interest in the field was reduced from 65% to 51%. This arrangement will accelerate the remaining development of the facility and fieldwork, and we currently anticipate first tertiary production by the middle of 2018. CAPITAL RESOURCES AND LIQUIDITY Overview. Our primary sources of capital and liquidity are our cash flows from operations and availability of borrowing capacity under our senior secured bank credit facility. As a result of the significant reduction in oil prices discussed above and less advantageous hedge positions, our cash flow from operations has significantly decreased, from $864.3 million during 2015 to $219.2 million during 2016. The preservation of cash and liquidity remains a significant priority for us in the current oil price environment. We have taken steps to lower our costs in all categories of our business, and we have made significant progress in that regard. Over the past year, we have also amended our senior secured bank credit facility to relax certain financial performance covenants through 2018 (see Senior Secured Bank Credit Facility below). As of December 31, 2016, we had $301.0 million drawn on our $1.05 billion senior secured bank credit facility, leaving us $673.7 million of current liquidity after consideration of $75.3 million of outstanding letters of credit. This liquidity, coupled with our other cost saving and liquidity preservation measures and the improvement in oil prices, should be sufficient to cover any foreseeable cash flow shortfall and fund our capital and operating cash outflows. In order to provide a level of price protection to a portion of our oil production, we have entered into a combination of oil swaps, collars, and three-way collars through the fourth quarter of 2017 (see Results of Operations – Commodity Derivative Contracts below). While a portion of these derivatives entered into in early 2016 are fixed-price swaps at prices that do not support capital spending levels which would grow our production, they do at least cover our most recent total cash operating costs, which were in a per-barrel range in the mid-$30’s during 2016 (including corporate overhead and interest), thereby minimizing the amount needed to be drawn under our senior secured bank credit facility for day-to-day operations. Since we do not expect oil prices to recover in the foreseeable future to recent historical highs of 2014, we must adjust our business to compete in an oil price environment that is likely not as robust as it was a few years ago, requiring reductions in overall debt levels over time. We made significant progress in this endeavor during 2016 with a net reduction in our debt 40 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations principal of $530.4 million (see Note 4, Long-Term Debt, to the Consolidated Financial Statements). Our subordinated debt is currently trading significantly higher than it was during the first half of 2016, making it more difficult to make accretive exchanges or repurchases of this debt. We would like to reduce our debt further if possible, and we plan to monitor the market and be opportunistic in our debt transactions based upon market conditions. These potential transactions could include purchases of our subordinated debt in the open market, cash tenders for our debt or public or privately negotiated debt exchanges, and future potential debt reduction with proceeds of issuances of equity, asset sales and other cash-generating activities. We may utilize a portion of the availability under our senior secured bank credit facility for such repurchases and may also consider other forms of capital such as additional second lien notes or other senior notes. Senior Secured Bank Credit Facility. In December 2014, we entered into an Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent, and other lenders party thereto (the “Bank Credit Agreement”). In October 2016, as part of our semiannual borrowing base redetermination, the borrowing base and lender commitments for our Bank Credit Agreement were reaffirmed at $1.05 billion, with our next borrowing base redetermination scheduled for May 2017. As of December 31, 2016, we had $301.0 million of debt outstanding and $75.3 million in letters of credit under the Bank Credit Agreement. In order to provide more flexibility in managing our balance sheet, the credit extended by our lenders, and continuing compliance with financial performance covenants in this low oil price environment, we entered into three amendments to the Bank Credit Agreement between May 2015 and April 2016 making the following modifications to the Bank Credit Agreement: • • • • • for 2016 and 2017, the maximum permitted ratio of consolidated total net debt to consolidated EBITDAX covenant was suspended and replaced by a maximum permitted ratio of consolidated senior secured debt to consolidated EBITDAX covenant of 3.0 to 1.0 (only debt under our Bank Credit Agreement is considered consolidated senior secured debt for purposes of this ratio); for 2016 and 2017, a new covenant was added to require a minimum permitted ratio of consolidated EBITDAX to consolidated interest charges of 1.25 to 1.0; allowing for the incurrence of up to $1.0 billion of junior lien debt (subject to customary requirements), with $385.1 million of future incurrence available as of December 31, 2016; limiting unrestricted cash and cash equivalents to $225 million if more than $250 million of borrowings are outstanding under the Bank Credit Agreement; and limiting the amount spent on repurchases or other redemptions of our senior subordinated notes to $225 million, with up to $148.3 million of this capacity remaining available as of December 31, 2016. Additionally, we are required to maintain a current ratio, as determined under the Bank Credit Agreement, of not less than 1.0 to 1.0. Beginning in the first quarter of 2018, the ratio of consolidated total net debt to consolidated EBITDAX covenant will be reinstated, utilizing an annualized EBITDAX amount for the first, second, and third quarters of 2018 and building to a trailing four quarters by the end of 2018, with the maximum permitted ratios being 6.0 to 1.0 for the first quarter ending March 31, 2018, 5.5 to 1.0 for the second quarter ending June 30, 2018, and 5.0 to 1.0 for the third and fourth quarters ending September 30 and December 31, 2018, and returning to 4.25 to 1.0 for the first quarter ending March 31, 2019. Under these financial performance covenant calculations, as of December 31, 2016, our ratio of consolidated senior secured debt to consolidated EBITDAX was 0.72 to 1.0 (based upon a maximum permitted ratio of 3.0 to 1.0), our ratio of consolidated EBITDAX to consolidated interest charges was 2.46 to 1.0 (based upon a required ratio of not less than 1.25 to 1.0), and our current ratio was 3.04 to 1.0 (based upon a required ratio of not less than 1.0 to 1.0). Based upon our currently forecasted levels of production and costs, hedges in place as of February 22, 2017, and current oil commodity futures prices, we currently anticipate continuing to be in compliance with our financial performance covenants during 2017. The above description of our Bank Credit Agreement financial performance covenants and the changes provided for within the three amendments are qualified by the express language and defined terms contained in the Bank Credit Agreement, the First Amendment to the Bank Credit Agreement dated May 4, 2015, the Second Amendment to the Bank Credit Agreement dated February 17, 2016, and the Third Amendment to the Bank Credit Agreement dated April 18, 2016, each of which are filed as exhibits to our periodic reports filed with the SEC. 41 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations 2016 Debt Reduction Transactions. During 2016, we completed a series of privately negotiated debt exchanges and open-market debt repurchases, contributing to a net reduction of our debt principal balance of $530.4 million between December 31, 2015 and 2016. In May 2016, we entered into privately negotiated agreements to exchange $175.1 million principal amount of our Senior Subordinated Notes due 2021 (“2021 Notes”), $411.0 million principal amount of our 5½% Senior Subordinated Notes due 2022 (“2022 Notes”), and $471.7 million principal amount of our Senior Subordinated Notes due 2023 (“2023 Notes”) for $614.9 million principal amount of new 2021 Senior Secured Notes plus 40.7 million shares of Denbury common stock, resulting in a net reduction from these exchanges of $442.9 million in our debt principal. Our Bank Credit Agreement allows for the incurrence of up to $1.0 billion of junior lien debt, so after taking these exchanges into account, we have an additional $385.1 million of junior lien debt capacity that remains available to us. During 2016, we repurchased a total of $181.9 million principal amount of our existing senior subordinated notes in open- market transactions, consisting of $9.8 million principal amount of our 2021 Notes, $66.1 million principal amount of our 2022 Notes, and $106.0 million principal amount of our 2023 Notes for a total purchase price of $76.7 million, excluding accrued interest. The repurchases were made at prices ranging from approximately 25% to 75% of the principal amount of the individual senior subordinated notes. In connection with these series of transactions, during 2016 we recognized a $103.1 million gain on debt extinguishment, net of unamortized debt issuance costs written off. We currently estimate combined annual cash interest savings of approximately $7 million related to these repurchases and the exchange transactions. Our Bank Credit Agreement limits open-market repurchases of our senior subordinated notes to $225 million, and as of February 22, 2017, we have up to $148.3 million of remaining capacity for senior subordinated notes repurchases or other redemptions. 2017 Capital Spending. We currently anticipate that our full-year 2017 capital budget, excluding capitalized interest and acquisitions, will be approximately $300 million, an increase of 44% over 2016 spending levels, which includes approximately $55 million in capitalized internal acquisition, exploration and development costs and pre-production tertiary startup costs. This combined 2017 capital budget amount, excluding capitalized interest and acquisitions, compares to combined 2016 development capital spending of $208.6 million (see Capital Expenditure Summary below for a summary of actual 2016 expenditures). The 2017 capital budget, excluding capitalized interest and acquisitions, is comprised of the following: • • • • $175 million allocated for tertiary oil field expenditures; $60 million allocated for other areas, primarily non-tertiary oil field expenditures; $10 million to be spent on CO2 sources and pipelines; and $55 million for other capital items such as capitalized internal acquisition, exploration and development costs and pre-production tertiary startup costs. Based upon our currently forecasted levels of production and costs, commodity hedges in place, and current oil commodity futures prices, we intend to fund our development capital spending primarily with cash flow from operations, with any potential shortfall funded with incremental borrowings under our Bank Credit Agreement, under which as of December 31, 2016, we had ample available borrowing capacity to cover any foreseeable cash flow shortfall. If prices were to decrease or changes in operating results were to cause a reduction in anticipated 2017 cash flows significantly below our currently forecasted operating cash flows, we would likely reduce our capital expenditures. If we reduce our capital spending due to lower cash flows, any sizeable reduction would likely lower our anticipated production levels in future years. 42 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Capital Expenditure Summary. The following table reflects incurred capital expenditures (including accrued capital) for the years ended December 31, 2016, 2015 and 2014: In thousands Capital expenditures by project Tertiary oil fields Non-tertiary fields Capitalized internal costs (1) Oil and natural gas capital expenditures CO2 pipelines CO2 sources Other Capital expenditures, before acquisitions and capitalized interest Acquisitions of oil and natural gas properties Capital expenditures, before capitalized interest Capitalized interest Capital expenditures, total Year Ended December 31, 2016 2015 2014 $ 119,117 $ 199,923 $ 31,034 56,260 206,411 34 2,171 30 208,646 11,706 220,352 25,982 101,667 66,308 367,898 14,444 23,643 1,177 407,162 25,765 432,927 32,146 629,790 240,187 67,908 937,885 45,672 56,460 1,853 1,041,870 8,773 1,050,643 24,202 $ 246,334 $ 465,073 $ 1,074,845 (1) Includes capitalized internal acquisition, exploration and development costs and pre-production tertiary startup costs. Our 2016 capital expenditures and property acquisitions were fully funded with $219.2 million of cash flows from operations, plus additional funds provided by asset sales and borrowings on our senior secured bank credit facility. Our 2015 and 2014 capital expenditures and property acquisitions were fully funded with cash flows from operations of $864.3 million and $1.2 billion, respectively. Commitments and Obligations.

As is common in our industry, we commit to make certain expenditures on a regular basis as part of our ongoing development and exploration program. These commitments generally relate to projects that occur during the subsequent several months and are usually 43 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations part of our normal operating expenses or part of our capital budget (see 2017 Capital Spending above). We also have recurring expenditures for such things as accounting, engineering and legal fees; software maintenance; subscriptions; and other overhead-type items. Normally these expenditures do not change materially on an aggregate basis from year to year and are part of our general and administrative expenses. We have not attempted to estimate the amounts of these types of recurring expenditures in this table, as most could be quickly canceled with regard to any specific vendor, even though the expense itself may be required for our ongoing normal operations. For further discussion of our long-term commitments to purchase CO2, see Note 10, Commitments and Contingencies, to the Consolidated Financial Statements. (2) Commodity derivative liabilities represent the fair value of our commodity derivatives presented as liabilities in our Consolidated Balance Sheets as of December 31, 2016. The ultimate settlement amounts of our derivative obligations are unknown because they are subject to continuing market fluctuations. See further discussion of our commodity derivative contracts and their market price sensitivities in Market Risk Management below in this Management’s Discussion and Analysis of Financial Condition and Results of Operations, and in Note 8, Commodity Derivative Contracts, to the Consolidated Financial Statements. (3) Represents the estimated future asset retirement obligations on an undiscounted basis. The present value of the discounted asset retirement obligation is $149.1 million, as determined under the Asset Retirement and Environmental Obligations topic of the Financial Accounting Standards Board Codification (“FASC”), and is further discussed in Note 2, Asset Retirement Obligations, to the Consolidated Financial Statements. Off-Balance Sheet Arrangements. We have several operating leases relating to office space and other minor equipment leases. At December 31, 2016, we had a total of $75.3 million of letters of credit outstanding under our senior secured bank credit facility. Additionally, we have obligations for development and exploratory expenditures that arise from our normal capital expenditure program or from other transactions common to our industry, none of which are recorded on our balance sheet. These obligations are further described in Commitments and Obligations above. In addition, in order to recover our undeveloped proved reserves, we must also fund the associated future development costs estimated in our proved reserve reports, which are only included in the table above to the extent we have firm contracts. For a further discussion of our future development costs, see Supplemental Oil and Natural Gas Disclosures (Unaudited) to the Consolidated Financial Statements. In the second quarter of 2016, we amended our CO2 offtake agreement with Mississippi Power Company (“MSPC”), which amendment included increasing our offtake percentage from 70% to 100% of CO2 quantities produced and lowering the base price related to the cost of CO2, deliveries of which are currently expected to begin during the first half of 2017. Based on the amended terms in the agreement, we concluded for accounting purposes that the agreement contains an embedded lease related to the pipeline owned by MSPC used to transport CO2 to Denbury. We currently plan to record a capital lease on the balance sheet of approximately $110 million upon lease commencement. FINANCIAL OVERVIEW OF TERTIARY OPERATIONS As discussed in Item 1, Business and Properties – Oil and Natural Gas Operations – Enhanced Oil Recovery Overview above, our tertiary operations represent a significant portion of our overall operations and have become our primary strategic focus. The economics of a tertiary field and the related impact on our financial statements differ from a conventional oil and gas play and are explained further below. While it is difficult to accurately forecast future production, we believe our tertiary recovery operations provide significant long-term production growth potential at reasonable return metrics, with relatively low risk, assuming crude oil prices are at levels that support the development of those projects. We have been developing tertiary oil properties for over 17 years, and the financial impact of such operations is reflected in our historical financial statements. The summary below highlights our observations regarding how tertiary operations have impacted our financial statements. Finding and Development Costs. We currently expect finding and development costs (including future development and abandonment costs but excluding CO2 pipeline infrastructure capital expenditures) over the life of each field to be competitive with the industry average costs for other oil properties. See the definition of finding and development costs in the Glossary and Selected Abbreviations. 44 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Timing of Capital Costs. There is a significant delay between the initial capital expenditures on tertiary oil fields and the resulting production increases. We must build facilities, and often a CO2 pipeline to the field, before CO2 flooding can commence, and it usually takes six to twelve months before the field responds to the injection of CO2 (i.e., oil production commences). Further, we may spend significant amounts of capital before we can recognize any proved reserves from fields we flood and, even after a field has proved reserves, significant amounts of additional capital will usually be required to fully develop the field. Recognition of Proved Reserves. In order to recognize proved tertiary oil reserves, we must either demonstrate production resulting from the tertiary process or the field must be analogous to an existing tertiary flood. The magnitude of proved reserves that we can book in any given year will depend on our progress with new floods, the timing of the production response from new floods and the performance of our existing floods. Typically, a high percentage of the potential reserves for a tertiary field are recognized when a production response is initially observed, and generally only modest changes are made thereafter. Production Rates. The production rate at a tertiary flood can vary from quarter to quarter, as a tertiary field’s production may increase rapidly when wells respond to the CO2, plateau temporarily, and then resume growth as additional areas of the field are developed. During a tertiary flood life cycle, facility capacity is increased from time to time, which occasionally requires temporary shutdowns during installation, thereby causing temporary declines in production. We also find it difficult to precisely predict when any given well will respond to the injected CO2, as the CO2 seldom travels through the rock consistently due to heterogeneity in the oil-bearing formations. With the recently low oil prices, our pace of development has generally slowed, thereby leading to a less consistent growth pattern. We find all of these fluctuations to be normal, and generally expect oil production at a tertiary field to increase over time until the field is fully developed, albeit sometimes in inconsistent patterns. Operating Costs. Tertiary projects may be more expensive to operate than traditional industry operations because of the cost of injecting and recycling the CO2 (primarily due to the cost of the CO2 and the significant energy requirements to re- compress the CO2 back into a near-liquid state for re-injection purposes). The costs of our CO2 and the electricity required to recycle and inject this CO2 comprise over half of our typical tertiary operating expenses. Since these costs vary along with commodity and commercial electricity prices, they are highly variable and will increase in a high-commodity-price environment and decrease in a low-price environment. Most of our CO2 operating costs are allocated to our tertiary oil fields and recorded as lease operating expenses (following the commencement of tertiary oil production) at the time the CO2 is injected. These costs have historically represented approximately 20% to 25% of the total operating costs for our tertiary operations. Since we expense all of the operating costs to produce and inject our CO2 (following the commencement of tertiary oil production), operating costs per barrel for a new flood will be higher at the inception of CO2 injection projects because of minimal related oil production at that time. 45 Denbury Resources Inc.

(4) Noncash fair value gains (losses) on commodity derivatives is a non-GAAP measure and is different from “Commodity derivatives expense (income)” in the Consolidated Statements of Operations in that the noncash fair value gains (losses) on commodity derivatives represent only the net changes between periods of the fair market values of commodity derivative positions, and exclude the impact of settlements on commodity derivatives during the period, which were receipts on settlements of $84.2 million, $511.7 million and $1.4 million for the years ended December 31, 2016, 2015 and 2014, respectively. We believe that noncash fair value gains (losses) on commodity derivatives is a useful supplemental disclosure to “Commodity derivatives expense (income)” in order to differentiate noncash fair market value adjustments from receipts or payments upon settlements on commodity derivatives during the period. This supplemental disclosure is widely used within the industry and by securities analysts, banks and credit rating agencies in calculating EBITDA and in adjusting net income (loss) to present those measures on a comparative basis across companies, as well as to assess compliance with certain debt covenants. Noncash fair value gains (losses) on commodity derivatives is not a measure of financial or operating performance under GAAP, nor should it be considered in isolation or as a substitute for “Commodity derivatives expense (income)” in the Consolidated Statements of Operations.

(2) Includes non-tertiary production in the Rocky Mountain region related to the sale of remaining non-core assets in the Williston Basin of North Dakota and Montana, which closed in the third quarter of 2016. Total Production Total continuing production during 2016 averaged 62,998 BOE/d, including 38,548 Bbls/d from tertiary properties and 24,450 BOE/d from non-tertiary properties. Total continuing production excludes production from the Williston Assets that 48 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations were sold during the third quarter of 2016 and other minor property divestitures, which production totaled 1,005 BOE/d during 2016, compared to 1,993 BOE/d and 2,275 BOE/d produced from these properties during 2015 and 2014, respectively. Our 2016 total continuing production level represents a decrease of 7,870 BOE/d (11%) compared to 2015 levels. Approximately one-third of these 2016 production declines were attributable to production shut-in due to economics and weather-related shut-in production at Thompson and Conroe fields. The remaining decline is largely due to natural production declines; although we have some inclining production at our fields, we did not invest sufficient capital during 2016 to hold production flat. As of December 31, 2016, we estimate that approximately 1,900 BOE/d of production remained shut in attributable to uneconomic wells, compared to approximately 1,650 BOE/d of production shut in as of December 31, 2015. The increase during 2016 was largely attributable to the impact of oil price declines in early 2016, partially offset by volumes sold in connection with the Williston Asset sale, in addition to minor volumes returned to production during the second half of 2016. Our production during 2016 was 96% oil, consistent with oil production of 95% during 2015 and 2014. We currently anticipate 2017 average daily production will remain relatively flat with our exit rate in 2016 of roughly 60,000 BOE/d. Tertiary Production Oil production from our tertiary operations averaged 38,548 Bbls/d during 2016, a decrease of 3,054 Bbls/d (7%) from our 2015 tertiary production level of 41,602 Bbls/d. These declines were primarily due to planned facility downtime at Tinsley Field and natural production declines at our mature fields in the Gulf Coast region, partially offset by increased production due to continued CO2 enhanced oil recovery response at Delhi and Bell Creek fields. Production from Tinsley and Oyster Bayou fields are believed to have peaked and therefore are expected to generally decline in the future. Non-Tertiary Production Continuing production from our non-tertiary operations averaged 24,450 BOE/d during 2016, a decrease of 4,816 BOE/ d (16%) compared to 2015 levels. These production declines include weather-related downtime at Thompson and Conroe fields, as noted above, and production attributable to wells shut in as uneconomic to either produce or repair due to commodity prices. When combined, these weather-related downtime and shut-in production impacts resulted in a production decline of approximately 2,500 BOE/d when compared to 2015. In addition, the changes include natural production declines at our non- tertiary properties in the Rocky Mountain and Gulf Coast regions. Oil and Natural Gas Revenues Oil and natural gas revenues decreased 23% between 2015 and 2016 and decreased 49% between 2014 and 2015. The changes in our oil and natural gas revenues are due to changes in production quantities and commodity prices (excluding any impact of our commodity derivative contracts), as reflected in the following table: In thousands Change in oil and natural gas revenues due to: Decrease in production Decrease in commodity prices Total decrease in oil and natural gas revenues Year Ended December 31, 2016 vs. 2015 Year Ended December 31, 2015 vs. 2014 Decrease in Revenues Percentage Decrease in Revenues Decrease in Revenues Percentage Decrease in Revenues $ $ (144,548) (132,727) (277,275) (12)% $ (11)% (23)% $ (50,093) (1,109,354) (1,159,447) (2)% (47)% (49)% 49 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Excluding any impact of our commodity derivative contracts, our average net realized commodity prices and NYMEX differentials were as follows during 2016, 2015 and 2014: Average net realized prices Oil price per Bbl Natural gas price per Mcf Price per BOE Average NYMEX differentials Oil per Bbl Natural gas per Mcf Year Ended December 31, 2016 2015 2014 $ $ 41.12 $ 47.30 $ 1.98 39.95 2.35 45.61 (2.29) $ (0.58) (1.55) $ (0.28) 90.74 4.07 87.33 (2.21) (0.20) As reflected in the table above, our average net realized oil price, excluding the impact of commodity derivative contracts, decreased 13% during 2016 from the average price received during 2015. Company-wide average oil price differentials were $2.29 per Bbl below NYMEX in 2016, compared to an average differential of $1.55 per Bbl below NYMEX in 2015 and $2.21 per Bbl below NYMEX in 2014. The decline in our average oil price differentials between 2015 and 2016 was principally due to weakening of our Gulf Coast region LLS price differentials, offset in part by Rocky Mountain region price differentials described below. Prices received in a regional market fluctuate frequently and can differ from NYMEX pricing due to a variety of reasons, including supply and/or demand factors, crude oil quality, and location differentials. The oil differentials we received in the Gulf Coast and Rocky Mountain regions are discussed in further detail below. Our average NYMEX oil differential in the Gulf Coast region was a negative $1.42 per Bbl during 2016, compared to a positive $0.49 per Bbl and $1.73 per Bbl during 2015 and 2014, respectively. These differentials are impacted significantly by the changes in prices received for our crude oil sold under LLS index prices relative to the change in NYMEX prices, as well as various other price adjustments such as those noted above. The quarterly average LLS-to-NYMEX differential (on a trade-month basis) averaged a positive $1.70 per Bbl, $3.72 per Bbl and $3.88 per Bbl during 2016, 2015 and 2014, respectively. During 2016, we sold approximately 60% of our crude oil at prices based on, or partially tied to, the LLS index price, and the balance at prices based on various other indexes tied to NYMEX prices, primarily in the Rocky Mountain region. NYMEX oil differentials in the Rocky Mountain region averaged $3.97 per Bbl below NYMEX during 2016, compared to an average differential of $5.60 per Bbl below NYMEX in 2015 and $10.19 per Bbl below NYMEX in 2014. Differentials in the Rocky Mountain region can fluctuate significantly on a month-to-month basis due to weather, refinery or transportation issues, and Canadian and U.S. crude oil price index volatility. Commodity Derivative Contracts From time to time, we enter into oil and natural gas derivative contracts to provide an economic hedge of our exposure to commodity price risk associated with anticipated future oil and natural gas production and to provide more certainty to our future cash flows. These contracts have historically consisted of price floors, collars, three-way collars, fixed-price swaps, and fixed-price swaps enhanced with a sold put. 50 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations The following table summarizes the impact our commodity derivative contracts had on our operating results for 2016, 2015 and 2014: In thousands 2016 Three Months Ended March 31 June 30 September 30 December 31 Full Year Receipt (payment) on settlements of commodity derivatives $ 72,227 $ 52,026 $ (7,295) $ (32,777) $ 84,181 Noncash fair value gains (losses) on commodity derivatives (1) (95,053) (150,235) 28,519 4,644 (212,125) Commodity derivatives income (expense) $ (22,826) $ (98,209) $ 21,224 $ (28,133) $ (127,944) 2015 Receipt on settlements of commodity derivatives Noncash fair value losses on commodity derivatives (1) Commodity derivatives income (expense) $ $ 148,465 (65,389) 83,076 $ $ 124,151 $ 160,677 (173,077) (68,649) (48,926) $ 92,028 $ $ 78,406 (56,585) 21,821 $ $ 511,699 (363,700) 147,999 2014 Receipt (payment) on settlements of commodity derivatives $ (27,169) $ (50,172) $ (24,914) $ 103,676 $ 1,421 Noncash fair value gains (losses) on commodity derivatives (1) (49,500) (124,599) 277,179 450,754 553,834 Commodity derivatives income (expense) $ (76,669) $ (174,771) $ 252,265 $ 554,430 $ 555,255 (1) Noncash fair value gains (losses) on commodity derivatives is a non-GAAP measure.

See also the Glossary and Selected Abbreviations for the definition of noncash fair value gains (losses) on commodity derivatives. In order to provide a level of price protection to a portion of our oil production, we have entered into a combination of oil swaps, collars, and three-way collars through the fourth quarter of 2017. See Note 8, Commodity Derivative Contracts, to the Consolidated Financial Statements for additional details of our outstanding commodity derivative contracts as of December 31, 2016, and Market Risk Management below for additional discussion.

Management’s Discussion and Analysis of Financial Condition and Results of Operations (2) If oil prices were to average less than the sold put price, receipts on settlement would be limited to the difference between the floor price and the sold put price. Based on current futures prices as of February 22, 2017, which average approximately $54 per Bbl for the first half of 2017, and the fixed-price swaps that we have in place, we currently expect that we would make cash payments of approximately $58 million during the first half of 2017 upon settlement of these contracts, the amount of which is dependent upon fluctuations in future NYMEX oil prices in relation to the fixed prices of these swaps, which have a weighted average price of $43.63 per Bbl. Commodity derivative contracts in place covering the second half of 2017 solely include collars and three-way collars. Based on current contracts in place and NYMEX oil futures prices as of February 22, 2017, minimal settlements are currently expected during the second half of 2017. Changes in commodity prices, expiration of contracts, and new commodity contracts entered into cause fluctuations in the estimated fair value of our oil derivative contracts. Because we do not utilize hedge accounting for our commodity derivative contracts, the period-to-period changes in the fair value of these contracts, as outlined above, are recognized in our statements of operations.

Our lease operating costs have declined significantly as a result of our cost reduction efforts, as well as general market decreases in the prices of many of the components of these costs. The reduction was due to cost decreases in most categories of lease operating expenses, the most significant of which included (1) a decrease in workover costs and repairs as a result of reduced failures through root-cause analysis and fewer well repairs in 2016 as more wells were uneconomic to repair based on low commodity prices, (2) lower CO2 expense resulting from a 32% decrease in CO2 injection volumes, (3) lower power costs due to lower usage, and (4) lower company labor costs resulting from a reduction in force. On a per-BOE basis, our total lease operating expenses during 2016 decreased from 2015 levels; however, the decrease on a percentage basis was not as large as the absolute-dollar decrease, as our lower production between the periods offset some of the cost reductions. Currently, our CO2 expense comprises approximately 20% of our typical tertiary lease operating expenses, and for the CO2 reserves we already own, consists of CO2 production expenses, and for the CO2 reserves we do not own, consists of our purchase of CO2 from royalty and working interest owners and industrial sources. During the year ended December 31, 2016, 52 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations approximately 57% of the CO2 utilized in our CO2 floods consisted of CO2 owned and produced by us (our net revenue interest). The price we pay others for CO2 varies by source and is generally indexed to oil prices. When combining the production cost of the CO2 we own with what we pay third parties for CO2, our average cost of CO2 during 2016 was approximately $0.38 per Mcf, including taxes paid on CO2 production but excluding depletion, depreciation and amortization of capital expended at our CO2 source fields and industrial sources. This per-Mcf CO2 cost during 2016 was slightly higher than the $0.35 per Mcf comparable measure during 2015 due primarily to a lower utilization of CO2, while certain pipeline and processing costs are relatively fixed, partially offset by higher utilization of industrial-source CO2, which has a higher average cost than our naturally-occurring CO2 sources. Marketing and Plant Operating Expenses Marketing and plant operating expenses primarily consist of amounts incurred related to the marketing, processing, and transportation of oil and natural gas production, and to a lesser extent expenses related to our Riley Ridge gas processing facility. Marketing and plant operating expenses were $57.5 million, $55.7 million and $64.4 million during 2016, 2015 and 2014, respectively. Taxes Other than Income Taxes other than income includes production, ad valorem and franchise taxes. Taxes other than income decreased $32.1 million (29%) between 2015 and 2016, due primarily to a decrease in production taxes resulting from lower oil and natural gas revenues and a decrease in the assessed value of our properties resulting in lower ad valorem taxes. General and Administrative Expenses (“G&A”) In thousands, except per-BOE data and employees 2016 2015 2014 Gross cash compensation and administrative costs $ 271,049 $ 328,802 $ 352,651 Year Ended December 31, Gross stock-based compensation Operator labor and overhead recovery charges Capitalized exploration and development costs Net G&A expense G&A per BOE Net administrative costs Net stock-based compensation Net G&A expense Employees as of December 31 21,042 (133,727) (48,438) 109,926 4.08 0.61 4.69 1,058 $ $ $ 39,285 (161,182) (62,341) 144,564 4.39 1.05 5.44 1,356 $ $ $ 39,532 (171,661) (62,179) 158,343 4.81 1.02 5.83 1,523 $ $ $ Gross cash compensation and administrative costs on an absolute-dollar basis decreased $57.8 million (18%) between 2015 and 2016, primarily due to lower employee-related costs such as salaries, bonus accruals and long-term incentives. As part of our efforts to reduce overhead and operating costs in response to the significant decline in oil prices, we reduced our employee headcount in mid-2015 and further reduced our employee headcount in February 2016 through involuntary workforce reductions, which contributed to an overall headcount reduction of approximately 31% between December 31, 2014 and December 31, 2016. The severance-related payments associated with the 2016 workforce reduction were approximately $9.3 million. Net G&A expense on a per-BOE basis decreased 14% between 2015 and 2016. This decrease was primarily based upon the changes noted in gross cash compensation and administrative costs, partially offset by lower operator labor and overhead recovery charges and lower production volumes and lower capitalized exploration and development costs. 53 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Gross stock-based compensation on an absolute-dollar basis decreased $18.2 million (46%) during 2016 compared to 2015 due to the reduction in headcount mentioned above, the reduction in stock compensation expense associated with our performance share awards for our executive officers which vested in 2016 or are projected to vest in future periods being below target levels, and the postponement of our customary annual long-term incentive award grants from January in prior years to early July in 2016, resulting in six months of expense for those grants rather than twelve. Our well operating agreements allow us, when we are the operator, to charge a well with a specified overhead rate during the drilling phase and also to charge a monthly fixed overhead rate for each producing well. In addition, salaries associated with field personnel are initially recorded as gross cash compensation and administrative costs and subsequently reclassified to lease operating expenses or capitalized to field development costs to the extent those individuals are dedicated to oil and natural gas production, exploration, and development activities.

See below for further discussion. (2) Includes commitment fees but excludes debt issue costs and amortization of discount or premium. As reflected in the table above, cash interest during 2016 decreased when compared to 2015 due primarily to repurchasing a total of $181.9 million principal amount of our existing senior subordinated notes at a discount to par value in open-market transactions during 2016. In addition, we entered into privately negotiated transactions during the second quarter of 2016 to exchange $1,057.8 million principal amount of our senior subordinated notes for $614.9 million principal amount of our new 2021 Senior Secured Notes plus 40.7 million shares of Denbury common stock (see Capital Resources and Liquidity – 2016 Debt Reduction Transactions). Although these exchange transactions had minimal impact on our cash interest, as more fully described in Note 4, Long-Term Debt, to the Consolidated Financial Statements, the exchange transactions were accounted for in accordance with Financial Accounting Standards Board Codification 470-60, Troubled Debt Restructuring by Debtors, whereby $254.7 million of future interest on the 2021 Senior Secured Notes was recorded as debt as of the transaction date, which will be reduced as semiannual interest payments are made, with the remaining $22.8 million of future interest to be recognized as interest expense over the term of the 2021 Senior Secured Notes. Therefore, interest expense reflected in our Consolidated Statements of Operations on the 2021 Senior Secured Notes will be significantly lower than the actual cash interest payment. For 2016, $32.1 million of interest on the 2021 Senior Secured Notes was accounted for as debt, and is therefore not reflected as interest expense in the Consolidated Statements of Operations. During 2017, we currently expect approximately $50 million of interest on the 2021 Senior Secured Notes to be accounted for as debt, and will therefore not be reflected as interest expense in the Consolidated Statements of Operations. Noncash interest expense during 2016 increased when compared to prior year due to the $5.5 million write-off of debt issuance costs associated with our senior secured bank credit facility following the May 2016 redetermination which reduced 54 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations our borrowing base and lender commitments and the February 2016 amendment which reduced our lender commitments. Capitalized interest decreased $6.2 million (19%) during 2016, primarily due to a reduction in the number of projects that qualify for interest capitalization.

See below for further discussion. We adjust our DD&A rate each quarter for significant changes in our estimates of oil and natural gas reserves and costs. In addition, under full cost accounting rules, the divestiture of oil and natural gas properties generally does not result in gain or loss recognition; instead, the proceeds of the disposition reduce the full cost pool. As such, our DD&A rate has changed significantly over time, and it may continue to change in the future. DD&A of oil and natural gas properties and asset retirement obligations decreased 64% on an absolute-dollar basis and 59% on a per-BOE basis between 2015 and 2016, primarily due to a reduction in depletable costs associated with our reserves base resulting from the significant full cost pool ceiling test write-downs recognized during 2015 and 2016, as well as an overall reduction in future development costs, partially offset by reductions in proved oil and natural gas reserve quantities. The per-BOE decrease was also partially offset by a decrease in production volumes during 2016 when compared to 2015. Due to these factors, our depletion and depreciation rate of oil and natural gas properties decreased to $5.35 per BOE during the fourth quarter of 2016. Depletion and depreciation of our CO2 properties, pipelines, plants and other property and equipment decreased 11% on an absolute-dollar basis during 2016 from 2015 levels, primarily due to lower depletion associated with our CO2 properties resulting from a decrease in CO2 production during the period, with the difference on a per-BOE basis offset by the decrease in oil and natural gas production volumes between periods. We acquired the Riley Ridge Unit and the associated gas processing facility in 2010 and 2011 with the intent to separate for sale the natural gas and helium from the full well stream after construction of the gas processing facility was completed, and ultimately for the purpose of gaining a source of CO2 to utilize in flooding our fields in the Rocky Mountain region. Subsequently, issues arose related to contractor performance and design failure that caused significant delays and incremental costs to complete the facility. We placed the gas processing facility into service during the fourth quarter of 2013, and we were successful in running the facility for part of 2014 before additional issues arose related to optimal operation of the facility and sulfur build-up in the gas supply wells. In mid-2014, the gas processing facility was shut-in and to date remains shut-in. During this period, we have searched for and evaluated a number of potential options in an effort to remedy the existing issues, and our evaluation is still ongoing. Our current projected costs to remedy these issues and successfully operate the gas processing facility are not commercially reasonable investments based on a variety of factors, including (1) the substantial 55 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations capital expenditures required to implement any corrective option, (2) current projected commodity prices, and (3) our projections of our EOR activities and their timing, resulting CO2 requirements and other assumptions. Due to the extended shut-in status of the Riley Ridge gas processing facility and our recently updated analysis of cost estimates and engineering options to remedy the existing issues, we reassessed the estimated useful life of the gas processing facility and related assets during the fourth quarter of 2016 and recorded accelerated depreciation of $591.0 million to “Depletion, depreciation, and amortization” in the Consolidated Statements of Operations, which includes $55.3 million of intangible assets assigned to helium production rights at Riley Ridge. We plan to continue engineering work and analysis to determine if there are alternative options to remediate the sulfur build-up in the gas supply wells and to assess our ability to reduce the costs thereof; however, the timing of completion and results of such analysis are currently uncertain. Write-Down of Oil and Natural Gas Properties Under full cost accounting rules, we are required each quarter to perform a ceiling test calculation. Under these rules, the full cost ceiling value is calculated using the average first-day-of-the-month oil and natural gas price for each month during a 12-month rolling period through the end of each quarterly reporting period. The average first-day-of-the-month NYMEX oil price used in estimating our proved reserves has been in a precipitous and continuing decline throughout 2015 and 2016, with the average price declining from $94.99 per Bbl at December 31, 2014, to $50.28 per Bbl at December 31, 2015, and further to $42.75 per Bbl at December 31, 2016. In addition, the first-day-of-the-month average natural gas price for the preceding 12 months was $4.30 per MMBtu at December 31, 2014, $2.63 per MMBtu at December 31, 2015, and $2.55 per MMBtu at December 31, 2016. These falling prices have led to our recognizing full cost pool ceiling test write-downs totaling $810.9 million and $4.9 billion during 2016 and 2015, respectively. We did not record a ceiling test write-down during 2014. We currently do not expect to record an additional write-down in the first quarter of 2017 if oil and natural gas prices remain at or near late-February 2017 levels, as the 12-month average prices used in determining the full cost ceiling value will have stabilized or reflect slightly higher prices in the first quarter of 2017 than in the first quarter of 2016. See Item 1A, Risk Factors, and Critical Accounting Policies and Estimates – Full Cost Method of Accounting, Depletion and Depreciation and Oil and Natural Gas Properties for further discussion. 2015 Impairment of Goodwill We are required to test goodwill for impairment on an interim basis when we determine that it is more likely than not that the fair value of our reporting unit is less than its carrying amount. We recorded a goodwill impairment charge of $1.3 billion during 2015, to fully impair the carrying value of our goodwill. Other Expenses Other expenses totaled $37.4 million during 2016, primarily comprised of a $27.5 million cash payment to Evolution Petroleum Corporation pursuant to a settlement agreement entered into in June 2016. See Note 10, Commitments and Contingencies, to the Consolidated Financial Statements for further discussion.

Management’s Discussion and Analysis of Financial Condition and Results of Operations Our income tax provisions for 2016, 2015 and 2014 were based on an estimated statutory rate of approximately 38%. Our effective tax rate was consistent with our estimated statutory rate in 2014, while our 2016 and 2015 effective tax rates were lower than the statutory rate. Effective January 1, 2016, we adopted Accounting Standards Update 2016-09 (“ASU 2016-09”), Improvements to Employee Share-Based Payment Accounting, which impacted the timing of when excess tax benefits or tax shortfalls are recognized. Our effective tax rate for 2016 was lower than our estimated statutory rate primarily due to the impact of a tax shortfall on the stock-based compensation deduction (e.g., the compensation expense recognized in the financial statements was greater than the actual compensation realized, resulting in a shortfall in the income tax deduction for stock awards that vested during the period). Prior to the adoption of ASU 2016-09, this was recorded as an adjustment to equity. Our effective tax rate for 2015 was lower than our estimated statutory rate, as a significant portion of the book value of our goodwill impaired during 2015 had no related tax basis. Therefore, no corresponding deferred tax benefit was recognized related to that portion of the goodwill impairment. Our effective tax rates for 2016 and 2015 were further impacted by a tax valuation allowance, which also reduced the net deferred tax benefit recognized. As of December 31, 2016, we had $36.5 million of deferred tax assets associated with State of Louisiana net operating losses. As the result of a tax law enacted in the State of Louisiana effective June 30, 2015, which limits a company’s utilization of certain deductions, including our net operating loss carryforwards, we recognized tax valuation allowances totaling $33.6 million during 2015 and an additional $2.9 million during 2016 to reduce the carrying value of our deferred tax assets associated with State of Louisiana net operating losses. The valuation allowances will remain until the realization of future deferred tax benefits are more likely than not to become utilized. As of December 31, 2016, we had an unrecognized tax benefit of $5.4 million related to an uncertain tax position. The unrecognized tax benefit was recorded during 2015 as a direct reduction of the associated deferred tax asset and, if recognized, would not materially affect our annual effective tax rate. The tax benefit from an uncertain tax position will only be recognized if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based upon the technical merits of the position. We currently do not expect a material change to the uncertain tax position within the next 12 months. Our policy is to recognize penalties and interest related to uncertain tax positions in income tax expense; however, no such amounts were accrued related to the uncertain tax position as of December 31, 2016. The current income tax benefits recorded in 2015 and 2014 were in recognition of reinstated bonus depreciation becoming available in December 2015 and 2014, along with an increase in certain tax preference items. We currently expect to carryforward the 2015 benefits to offset taxable income in future periods. The 2014 benefit was carried back to our filed tax returns in prior years. The deferred income tax benefits during 2016 and 2015 were primarily due to the impact of the write- down of our oil and natural gas properties during the year, with 2016 further impacted by an accelerated depreciation charge associated with the Riley Ridge gas processing facility and related assets. In connection with the privately negotiated agreements to exchange a portion of our existing senior subordinated notes for 2021 Senior Secured Notes during 2016, we realized a tax gain due to the concession extended by our note holders. This tax gain was offset by net operating losses and other deferred tax asset attributes. As of December 31, 2016, we had tax-effected federal net operating loss carryforwards (“NOLs”) totaling $27.1 million, state NOLs totaling $42.6 million (before provision for valuation allowance), an estimated $51.1 million of enhanced oil recovery credits to carry forward related to our tertiary operations, $21.6 million of research and development credits, and $41.1 million of alternative minimum tax credits that can be utilized to reduce our current income taxes during 2017 or future years. Our state NOLs expire in various years, starting in 2019, although most do not begin to expire until 2036. Our enhanced oil recovery credits and research and development credits do not begin to expire until 2023 and 2031, respectively. 57 Denbury Resources Inc.

Management’s Discussion and Analysis of Financial Condition and Results of Operations MARKET RISK MANAGEMENT Debt We finance some of our acquisitions and other expenditures with fixed and variable rate debt. These debt agreements expose us to market risk related to changes in interest rates. At December 31, 2016, we had $301.0 million of debt outstanding on our senior secured bank credit facility. At this level of variable-rate debt, an increase or decrease of 10% in interest rates would have an immaterial effect on our interest expense. None of our existing debt has any triggers or covenants regarding our debt ratings with rating agencies, although under the NEJD financing lease, in light of credit downgrades in February 2016, we were required to provide a $41.3 million letter of credit to the lessor, which we provided on March 4, 2016. The letter of credit may be drawn upon in the event Denbury Onshore or Denbury fail to make a payment due under the pipeline financing lease agreement or upon other specified defaults set out in the pipeline financing lease agreement (filed as Exhibit 99.1 to the Form 8-K filed with the SEC on June 5, 2008). The fair values of our senior secured second lien notes and senior subordinated debt is based on quoted market prices. The following table presents the principal cash flows and fair values of our outstanding debt at December 31, 2016: In thousands Variable rate debt Senior Secured Bank Credit Facility (weighted average interest rate of 3.0% at December 31, 2016) Fixed rate debt 9% Senior Secured Second Lien Notes due 2021 5½% Senior Subordinated Notes due 2022 Other Subordinated Notes Oil and Natural Gas Derivative Contracts 2017 2019 2021 2022 2023 Total Fair Value $ — $ 301,000 $ — $ — $ — $ 301,000 $ 301,000 — — — — 2,250 — — — — — 614,919 215,144 — — — — — 772,912 — — — — — 622,297 — 614,919 215,144 772,912 622,297 2,250 657,164 193,630 674,366 499,393 2,250 Historically, we have entered into oil and natural gas derivative contracts to provide an economic hedge of our exposure to commodity price risk associated with anticipated future oil and natural gas production and to provide more certainty to our future cash flows. We do not hold or issue derivative financial instruments for trading purposes. Generally, these contracts have consisted of various combinations of price floors, collars, three-way collars, fixed-price swaps, and fixed-price swaps enhanced with a sold put. The production that we hedge has varied from year to year depending on our levels of debt, financial strength, and expectation of future commodity prices. In order to provide a level of price protection to a portion of our oil production, we have hedged a portion of our estimated oil production through 2017 using both NYMEX and LLS fixed-price swaps, collars and three-way collars. See also Note 8, Commodity Derivative Contracts, and Note 9, Fair Value Measurements, to the Consolidated Financial Statements for additional information regarding our commodity derivative contracts. All of the mark-to-market valuations used for our commodity derivatives are provided by external sources. We manage and control market and counterparty credit risk through established internal control procedures that are reviewed on an ongoing basis. We attempt to minimize credit risk exposure to counterparties through formal credit policies, monitoring procedures and diversification. All of our commodity derivative contracts are with parties that are lenders under our senior secured bank credit facility (or affiliates of such lenders). We have included an estimate of nonperformance risk in the fair value measurement of our commodity derivative contracts, which we have measured for nonperformance risk based upon credit default swaps or credit spreads. For accounting purposes, we do not apply hedge accounting to our commodity derivative contracts. This means that any changes in the fair value of these commodity derivative contracts will be charged to earnings on a quarterly basis instead of charging the effective portion to other comprehensive income and the ineffective portion to earnings. 59 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations At December 31, 2016, our commodity derivative contracts were recorded at their fair value, which was a net liability of $69.3 million, a $212.1 million decrease from the $142.8 million net asset recorded at December 31, 2015. This change is primarily related to the expiration of commodity derivative contracts during 2016, new commodity derivative contracts entered into during 2016 for future periods, and changes in oil futures prices between December 31, 2015 and 2016. Commodity Derivative Sensitivity Analysis Based on NYMEX and LLS crude oil futures prices as of December 31, 2016, and assuming both a 10% increase and decrease thereon, we would expect to make payments on our crude oil derivative contracts as shown in the following table: In thousands Based on: Futures prices as of December 31, 2016 $ 10% increase in prices 10% decrease in prices Payment (67,476) (101,247) (36,565) Our commodity derivative contracts are used as an economic hedge of our exposure to commodity price risk associated with anticipated future production. As a result, changes in receipts or payments of our commodity derivative contracts due to changes in commodity prices as reflected in the above table would be mostly offset by a corresponding increase or decrease in the cash receipts on sales of our oil and natural gas production to which those commodity derivative contracts relate. CRITICAL ACCOUNTING POLICIES AND ESTIMATES The preparation of financial statements in accordance with generally accepted accounting principles requires that we select certain accounting policies and make certain estimates and judgments regarding the application of those policies. Our significant accounting policies are included in Note 1, Significant Accounting Policies, to the Consolidated Financial Statements. These policies, along with the underlying assumptions and judgments by our management in their application, have a significant impact on our consolidated financial statements. Following is a discussion of our most critical accounting estimates, judgments and uncertainties that are inherent in the preparation of our financial statements. Full Cost Method of Accounting, Depletion and Depreciation and Oil and Natural Gas Properties Businesses involved in the production of oil and natural gas are required to follow accounting rules that are unique to the oil and gas industry. We apply the full cost method of accounting for our oil and natural gas properties. Another acceptable method of accounting for oil and natural gas production activities is the successful efforts method of accounting. In general, the primary differences between the two methods are related to the capitalization of costs and the evaluation for asset impairment. Under the full cost method, all geological and geophysical costs, exploratory dry holes and delay rentals are capitalized to the full cost pool, whereas under the successful efforts method such costs are expensed as incurred. In the assessment of impairment of oil and natural gas properties, the successful efforts method follows the Accounting for the Impairment or Disposal of Long-Lived Assets topic of the FASC, under which the net book value of assets is measured for impairment against the undiscounted future cash flows using commodity prices consistent with management expectations. Under the full cost method, the full cost pool (net book value of oil and natural gas properties) is measured against future cash flows discounted at 10% using the average first-day-of-the-month oil and natural gas price for each month during a 12-month rolling period through the end of each quarterly reporting period. The financial results for a given period could be substantially different depending on the method of accounting that an oil and gas entity applies. Further, we do not designate our oil and natural gas derivative contracts as hedging instruments for accounting purposes under the Derivatives and Hedging topic of the FASC (see below), and as a result, these contracts are not considered in the full cost ceiling test. We make significant estimates at the end of each period related to accruals for oil and natural gas revenues, production, capitalized costs and operating expenses. We calculate these estimates with our best available data, which includes, among other things, production reports, price posting, information compiled from daily drilling reports and other internal tracking devices, and analysis of historical results and trends. While management is not aware of any required revisions to its estimates, there will likely be future adjustments resulting from such things as revisions in estimated oil and natural gas volumes, changes 60 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations in ownership interests, payouts, joint venture audits, re-allocations by the purchasers or pipelines, or other corrections and adjustments common in the oil and gas industry, many of which will require retroactive application. These types of adjustments cannot be currently estimated or determined and will be recorded in the period during which the adjustment occurs. Under full cost accounting, the estimated quantities of proved oil and natural gas reserves used to compute depletion and the related present value of estimated future net cash flows therefrom used to perform the full cost ceiling test have a significant impact on the underlying financial statements. The process of estimating oil and natural gas reserves is very complex, requiring significant decisions in the evaluation of all available geological, geophysical, engineering and economic data. The data for a given field may also change substantially over time as a result of numerous factors, including additional development activity, evolving production history and continued reassessment of the viability of production under varying economic conditions. As a result, material revisions to existing reserve estimates may occur from time to time. Although every reasonable effort is made to ensure the reported reserve estimates represent the most accurate assessments possible, including the hiring of independent engineers to prepare reported estimates, the subjective decisions and variances in available data for various fields make these estimates generally less precise than other estimates included in our financial statement disclosures. Over the last four years, annual revisions to our reserve estimates, excluding any revisions related to changes in commodity prices, have averaged approximately 1.9% of the previous year’s estimates and have been both positive and negative. Changes in commodity prices also affect our reserve quantities. These changes in quantities affect our DD&A rate, and the combined effect of changes in quantities and commodity prices impacts our full cost ceiling test calculation. For example, we estimate that a 5% increase in our estimate of proved reserve quantities would have lowered our fourth quarter 2016 DD&A rate from $5.35 per BOE to approximately $5.12 per BOE, and a 5% decrease in our proved reserve quantities would have increased our DD&A rate to approximately $5.60 per BOE. Also, reserve quantities and their ultimate values, determined solely by our lenders, are the primary factors in determining the maximum borrowing base under our senior secured bank credit facility, particularly quantities and values of our proved developed producing reserves. Under full cost accounting rules, we are required each quarter to perform a ceiling test calculation. The net capitalized costs of oil and natural gas properties are limited to the lower of unamortized cost or the cost center ceiling. The cost center ceiling is defined as (1) the present value of estimated future net revenues from proved oil and natural gas reserves before future abandonment costs (discounted at 10%), based on the average first-day-of-the-month oil and natural gas price for each month during a 12-month rolling period prior to the end of a particular reporting period; plus (2) the cost of properties not being amortized; plus (3) the lower of cost or estimated fair value of unproved properties included in the costs being amortized, if any; less (4) related income tax effects. Our future net revenues from proved oil and natural gas reserves are not reduced for development costs related to the cost of drilling for and developing CO2 reserves nor those related to the cost of constructing CO2 pipelines, as we do not have to incur additional costs to develop the proved oil and natural gas reserves. Therefore, we include in the ceiling test, as a reduction of future net revenues, that portion of our capitalized CO2 costs related to CO2 reserves and CO2 pipelines that we estimate will be consumed in the process of producing our proved oil and natural gas reserves. The fair value of our oil and natural gas derivative contracts is not included in the ceiling test, as we do not designate these contracts as hedging instruments for accounting purposes. The cost center ceiling test is prepared quarterly. The average first-day-of-the-month NYMEX oil price used in estimating our proved reserves has precipitously and continually declined throughout 2015 and 2016, with the average price declining from $94.99 per Bbl at December 31, 2014, to $50.28 per Bbl at December 31, 2015, and further to $42.75 per Bbl at December 31, 2016. In addition, the first-day-of- the-month average natural gas price for the preceding 12 months was $4.30 per MMBtu at December 31, 2014, $2.63 per MMBtu at December 31, 2015, and $2.55 per MMBtu at December 31, 2016. These falling prices have led to our recognizing full cost pool ceiling test write-downs totaling $810.9 million and $4.9 billion during 2016 and 2015, respectively. We did not record a ceiling test write-down during 2014. We currently do not expect to record an additional write-down in the first quarter of 2017 if oil and natural gas prices remain at or near late-February 2017 levels, as the 12-month average prices used in determining the full cost ceiling value will have stabilized or reflect slightly higher prices in the first quarter of 2017 than in the first quarter of 2016. We exclude certain unevaluated costs from the amortization base and full cost ceiling test pending the determination of whether proved reserves can be assigned to such properties. These costs are transferred to the full cost amortization base in the course of these properties being developed, tested and evaluated. At least annually, we test these assets for impairment based on an evaluation of management’s expectations of future pricing, evaluation of lease expiration terms, and planned 61 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations project development activities. As a result of this analysis, we recognized impairments of $21.0 million and $17.9 million of our unevaluated costs during the years ended December 31, 2016 and 2015, respectively, whereby these costs were transferred to the full cost amortization base. We did not have an impairment of our unevaluated costs for the year ended December 31, 2014. Tertiary Injection Costs Our tertiary operations are conducted in reservoirs that have already produced significant amounts of oil over many years; however, in accordance with the rules for recording proved reserves, we cannot recognize proved reserves associated with enhanced recovery techniques such as CO2 injection until we can demonstrate production resulting from the tertiary process or unless the field is analogous to an existing flood. Our costs associated with the CO2 we produce (or acquire) and inject are principally our cash out-of-pocket costs of production, transportation and acquisition, and to pay royalties. We capitalize, as a development cost, injection costs in fields that are in their development stage, which means we have not yet seen incremental oil production due to the CO2 injections (i.e., a production response). These capitalized development costs will be included in our unevaluated property costs if there are not already proved tertiary reserves in that field. After we see a production response to the CO2 injections (i.e., the production stage), injection costs will be expensed as incurred, and any previously deferred unevaluated development costs will become subject to depletion upon recognition of proved tertiary reserves. During 2016, 2015 and 2014, we capitalized $17.3 million, $19.4 million and $20.7 million, respectively, of tertiary injection costs associated with our tertiary projects. Income Taxes We make certain estimates and judgments in determining our income tax expense for financial reporting purposes. These estimates and judgments occur in the calculation of certain tax assets and liabilities that arise from differences in the timing and recognition of revenue and expense for tax and financial reporting purposes. Our federal and state income tax returns are generally not prepared or filed before the consolidated financial statements are prepared; therefore, we estimate the tax basis of our assets and liabilities at the end of each period as well as the effects of tax rate changes, tax credits and net operating loss carryforwards. Adjustments related to these estimates are recorded in our tax provision in the period in which we finalize our income tax returns. Further, we must assess the likelihood that we will be able to recover or utilize our deferred tax assets (primarily our enhanced oil recovery credits and state loss carryforwards). If recovery is not likely, we must record a valuation allowance against such deferred tax assets for the amount we would not expect to recover, which would result in an increase to our income tax expense. As the result of a new tax law enacted in the State of Louisiana effective June 30, 2015, which limits a company’s utilization of certain deductions, including our net operating loss carryforwards, we recognized tax valuation allowances totaling $33.6 million during 2015 and an additional $2.9 million during 2016 to reduce the carrying value of our deferred tax assets. The valuation allowances will remain until the realization of future deferred tax benefits are more likely than not to become utilized. A 1% increase in our effective tax rate would have increased our calculated income tax expense (benefit) by approximately ($15.2 million), ($63.3 million) and $10.2 million for the years ended December 31, 2016, 2015 and 2014, respectively. See Note 5, Income Taxes, to the Consolidated Financial Statements and Results of Operations – Income Taxes above for further information concerning our income taxes. Fair Value Estimates The FASC defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. It does not require us to make any new fair value measurements, but rather establishes a fair value hierarchy that prioritizes the inputs to the valuation techniques used to measure fair value. Level 1 inputs are given the highest priority in the fair value hierarchy, as they represent observable inputs that reflect unadjusted quoted prices for identical assets or liabilities in active markets as of the reporting date, while Level 3 inputs are given the lowest priority, as they represent unobservable inputs that are not corroborated by market data. Valuation techniques that maximize the use of observable inputs are favored. See Note 9, Fair Value Measurements, to the Consolidated Financial Statements for disclosures regarding our recurring fair value measurements. 62 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Significant uses of fair value measurements include: • • assessment of impairment of long-lived assets; and recorded value of commodity derivative instruments. Impairment Assessment of Long-Lived Assets We test long-lived assets for impairment that are not subject to our quarterly full cost pool ceiling test, including a portion of our capitalized CO2 properties and pipelines, whenever events or changes in circumstances indicate that the carrying value may not be recoverable. The factors we assess to determine if a long-lived asset impairment test is necessary include, among other factors, a significant adverse change in the business climate that could affect the value of a long-lived asset, a significant decrease in the market price of an asset group, a significant adverse change in the extent or manner in which a long-lived asset (asset group) is being used or in its physical condition, or a current-period operating or cash flow loss combined with a history of operating or cash flow losses or a projection or forecast that demonstrates continuing losses associated with the use of a long-lived asset (asset group). We perform our long-lived asset impairment test by comparing the net carrying costs of our long-lived asset groups to the respective expected future undiscounted net cash flows that are supported by these long-lived assets which include production of our probable and possible oil and natural gas reserves. If the undiscounted net cash flows are below the net carrying costs for an asset group, we must record an impairment loss by the amount, if any, that net carrying costs exceed the fair value of the long-lived asset group. Management assumptions impacting expected future undiscounted net cash flows include market estimates of future commodity prices, projections of estimated reserve quantities, projections of future rates of production, timing and amount of future development and operating costs, projected availability and cost of CO2, projected recovery factors of tertiary reserves and risk-adjustment factors applied to the net cash flows. Due to an increase in cost estimates to correct and remedy the sulfur deposition issues at Riley Ridge provided in the results of preliminary engineering design efforts received late in 2016 and the potential impact on the utilization of Riley Ridge assets within the Rocky Mountain asset group, we performed a long-lived asset impairment test for the Rocky Mountain asset group during the fourth quarter of 2016. The undiscounted net cash flows for our asset group exceeded the net carrying costs; thus, step two of the impairment test was not required and no impairment was recorded. We acquired the Riley Ridge Unit and the associated gas processing facility in 2010 and 2011 with the intent to separate for sale the natural gas and helium from the full well stream after construction of the gas processing facility was completed, and ultimately for the purpose of gaining a source of CO2 to utilize in flooding our fields in the Rocky Mountain region. Subsequently, issues arose related to contractor performance and design failure that caused significant delays and incremental costs to complete the facility. We placed the gas processing facility into service during the fourth quarter of 2013, and we were successful in running the facility for part of 2014 before additional issues arose related to optimal operation of the facility and sulfur build-up in the gas supply wells. In mid-2014, the gas processing facility was shut-in and to date remains shut-in. During this period, we have searched for and evaluated a number of potential options in an effort to remedy the existing issues, and our evaluation is still ongoing. Our current projected costs to remedy these issues and successfully operate the gas processing facility are not commercially reasonable investments based on a variety of factors, including (1) the substantial capital expenditures required to implement any corrective option, (2) current projected commodity prices, and (3) our projections of our EOR activities and their timing, resulting CO2 requirements and other assumptions. Due to the extended shut-in status of the Riley Ridge gas processing facility and our recently updated analysis of cost estimates and engineering options to remedy the existing issues, we reassessed the estimated useful life of the gas processing facility and related assets during the fourth quarter of 2016 and recorded accelerated depreciation of $591.0 million to “Depletion, depreciation, and amortization” in the Consolidated Statements of Operations, which includes $55.3 million of intangible assets assigned to helium production rights at Riley Ridge. We plan to continue engineering work and analysis to determine if there are alternative options to remediate the sulfur build-up in the gas supply wells and to assess our ability to reduce the costs thereof; however, the timing of completion and results of such analysis are currently uncertain. 63 Denbury Resources Inc. Management’s Discussion and Analysis of Financial Condition and Results of Operations Oil and Natural Gas Derivative Contracts Historically, we have entered into oil and natural gas derivative contracts to provide an economic hedge of our exposure to commodity price risk associated with future oil and natural gas production and to provide more certainty to our future cash flows. We do not hold or issue derivative financial instruments for trading purposes. Generally, these contracts have consisted of various combinations of price floors, collars, three-way collars, fixed-price swaps and fixed-price swaps enhanced with a sold put. Our derivative financial instruments are recorded on the balance sheet as either an asset or liability measured at fair value. The valuation methods used to measure the fair values of these assets and liabilities require considerable management judgment and estimates to derive the inputs necessary to determine fair value estimates, such as forward prices for commodities, interest rates, volatility factors and credit worthiness, as well as other relevant economic measures. We do not apply hedge accounting to our commodity derivative contracts under the FASC Derivatives and Hedging topic; accordingly, changes in the fair value of these instruments are recognized in earnings on a quarterly basis instead of charging the effective portion to other comprehensive income and the balance to earnings. While we may experience more volatility in our net income (loss) than if we were to apply hedge accounting treatment as permitted by the FASC Derivatives and Hedging topic, we believe that for us, the benefits associated with applying hedge accounting do not outweigh the cost, time and effort to comply with hedge accounting. Environmental and Litigation Contingencies The Company makes judgments and estimates in recording liabilities for contingencies such as environmental remediation or ongoing litigation. Liabilities are recorded when it is both probable that a loss has been incurred and such loss is reasonably estimable. Assessments of liabilities are based on information obtained from independent and in-house experts, loss experience in similar situations, actual costs incurred, and other case-by-case factors. Actual costs can vary from such estimates for a variety of reasons. The costs of environmental remediation or litigation can vary from estimates due to new developments regarding the facts and circumstances of each event, including in the case of environmental remediation, the timing of remediation, our understanding of the environmental impact, remediation methods available, and regulatory requirements, and in the case of litigation, differing interpretations of laws and facts and assessments of damages asserted and/or incurred. Use of Estimates See Note 1, Significant Accounting Policies, to the Consolidated Financial Statements for a discussion of our use of estimates. Recent Accounting Pronouncements See Note 1, Significant Accounting Policies, to the Consolidated Financial Statements for a discussion of recent accounting pronouncements. FORWARD-LOOKING INFORMATION The data and/or statements contained in this Annual Report on Form 10-K that are not historical facts, including, but not limited to, statements found in the sections entitled “Business and Properties” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” are forward-looking statements, as that term is defined in Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve a number of risks and uncertainties. Such forward-looking statements may be or may concern, among other things, financial forecasts, future hydrocarbon prices and timing and degree of any price recovery versus the length or severity of the current commodity price downturn, current or future liquidity sources or their adequacy to support our anticipated future activities, our ability to further reduce our debt levels, possible future write-downs of oil and natural gas reserves, together with assumptions based on current and projected oil and gas prices and oilfield costs, current or future expectations or estimations of our cash flows, availability of capital, borrowing capacity, future interest rates, availability of advantageous commodity derivative contracts or the predicted cash flow benefits therefrom, forecasted capital expenditures, drilling activity or methods, including the timing and location thereof, estimated timing of commencement of CO2 flooding of particular fields or areas, dates of completion of to-be-constructed industrial plants and the initial date of capture of CO2 from such plants, timing of CO2 injections and initial production responses in tertiary flooding projects, acquisition plans and proposals and dispositions, development activities, finding costs, anticipated 64 Denbury Resources Inc.

Also in our opinion, the Company 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 (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these financial statements and on the Company’s internal control over financial reporting based on our integrated audits. We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of 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 of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ PricewaterhouseCoopers LLP PricewaterhouseCoopers LLP Dallas, Texas March 1, 2017 67 Denbury Resources Inc.

Principles of Reporting and Consolidation The consolidated financial statements herein have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and include the accounts of Denbury and entities in which we hold a controlling financial interest. Undivided interests in oil and gas joint ventures are consolidated on a proportionate basis. All intercompany balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of certain assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during each reporting period. Management believes its estimates and assumptions are reasonable; however, such estimates and assumptions are subject to a number of risks and uncertainties that may cause actual results to differ materially from such estimates. Significant estimates underlying these financial statements include (1) the fair value of financial derivative instruments; (2) the estimated quantities of proved oil and natural gas reserves used to compute depletion of oil and natural gas properties, the related present value of estimated future net cash flows therefrom and the ceiling test; (3) future net cash flow estimates used in the impairment assessment of long-lived assets; (4) the estimated quantities of proved and probable CO2 reserves used to compute depletion of CO2 properties; (5) estimated useful lives used to compute depreciation and amortization of long-lived assets; (6) accruals related to oil and natural gas sales volumes and revenues, capital expenditures and lease operating expenses; (7) the estimated costs and timing of future asset retirement obligations; (8) estimates made in the calculation of income taxes; and (9) estimates made in determining the fair values for purchase price allocations, including goodwill. While management is not aware of any significant revisions to any of its current year-end estimates, there will likely be future revisions to its estimates resulting from matters such as revisions in estimated oil and natural gas volumes, changes in ownership interests, payouts, joint venture audits, re-allocations by purchasers or pipelines, or other corrections and adjustments common in the oil and natural gas industry, many of which require retroactive application. These types of adjustments cannot be currently estimated and will be recorded in the period in which the adjustment occurs. Reclassifications Certain prior period amounts have been reclassified to conform to the current year presentation. On the Consolidated Balance Sheets, (1) debt issuance costs associated with our senior subordinated notes have been reclassified from “Other assets” to “Long-term debt, net of current portion” and (2) deferred tax assets have been reclassified from “Deferred tax assets, net” to “Deferred tax liabilities, net.” Such reclassifications were made as a result of our adoption of new accounting pronouncements described in Recent Accounting Pronouncements – Recently Adopted below and had no impact on our previously reported net income (loss) or cash flows. Cash Equivalents We consider all highly liquid investments to be cash equivalents if they have maturities of three months or less at the date of purchase. 73 Denbury Resources Inc. Notes to Consolidated Financial Statements Oil and Natural Gas Properties Capitalized Costs. We follow the full cost method of accounting for oil and natural gas properties. Under this method, all costs related to the acquisition, exploration and development of oil and natural gas reserves are capitalized and accumulated in a single cost center representing our activities, which are undertaken exclusively in the United States. Such costs include lease acquisition costs, geological and geophysical expenditures, lease rentals on undeveloped properties, costs of drilling both productive and nonproductive wells, capitalized interest on qualifying projects, and general and administrative expenses directly related to exploration and development activities, and do not include any costs related to production, general corporate overhead or similar activities. We assign the purchase price of oil and natural gas properties we acquire to proved and unevaluated properties based on the estimated fair values as defined in the Financial Accounting Standards Board Codification (“FASC”) Fair Value Measurement topic. Proceeds received from disposals are credited against accumulated costs except when the sale represents a significant disposal of reserves, in which case a gain or loss would be recognized. A disposal of 25% or more of our proved reserves would be considered significant. Depletion and Depreciation. The costs capitalized, including production equipment and future development costs, are depleted or depreciated using the unit-of-production method, based on proved oil and natural gas reserves as determined by independent petroleum engineers. Oil and natural gas reserves are converted to equivalent units on a basis of 6,000 cubic feet of natural gas to one barrel of crude oil. Under full cost accounting, we may exclude certain unevaluated costs from the amortization base pending determination of whether proved reserves can be assigned to such properties. The costs classified as unevaluated are transferred to the full cost amortization base as the properties are developed, tested and evaluated. At least annually, we test these assets for impairment based on an evaluation of management’s expectations of future pricing, evaluation of lease expiration terms, and planned project development activities. As a result of this analysis, we recognized impairments of our unevaluated costs totaling $21.0 million and $17.9 million during the years ended December 31, 2016 and 2015, respectively, whereby these costs were transferred to the full cost amortization base. We did not have an impairment of our unevaluated costs during the year ended December 31, 2014. Write-Down of Oil and Natural Gas Properties. The net capitalized costs of oil and natural gas properties are limited to the lower of unamortized cost or the cost center ceiling. The cost center ceiling is defined as (1) the present value of estimated future net revenues from proved oil and natural gas reserves before future abandonment costs (discounted at 10%), based on the average first-day-of-the-month oil and natural gas price for each month during a 12-month rolling period prior to the end of a particular reporting period; plus (2) the cost of properties not being amortized; plus (3) the lower of cost or estimated fair value of unproved properties included in the costs being amortized, if any; less (4) related income tax effects. Our future net revenues from proved oil and natural gas reserves are not reduced for development costs related to the cost of drilling for and developing CO2 reserves nor those related to the cost of constructing CO2 pipelines, as we do not have to incur additional costs to develop the proved oil and natural gas reserves. Therefore, we include in the ceiling test, as a reduction of future net revenues, that portion of our capitalized CO2 costs related to CO2 reserves and CO2 pipelines that we estimate will be consumed in the process of producing our proved oil and natural gas reserves. The fair value of our oil and natural gas derivative contracts is not included in the ceiling test, as we do not designate these contracts as hedge instruments for accounting purposes. The cost center ceiling test is prepared quarterly. The average first-day-of-the-month NYMEX oil price used in estimating our proved reserves has been in a precipitous and continuing decline throughout 2015 and 2016, with the average price declining from $94.99 per Bbl at December 31, 2014, to $50.28 per Bbl at December 31, 2015, and further to $42.75 per Bbl at December 31, 2016. In addition, the first- day-of-the-month average natural gas price for the preceding 12 months was $4.30 per MMBtu at December 31, 2014, $2.63 per MMBtu at December 31, 2015, and $2.55 per MMBtu at December 31, 2016. These falling prices have led to our recognizing full cost pool ceiling test write-downs totaling $810.9 million and $4.9 billion during 2016 and 2015, respectively. We did not record a ceiling test write-down during 2014. Joint Interest Operations. Substantially all of our oil and natural gas exploration and production activities are conducted jointly with others. These financial statements reflect only our proportionate interest in such activities, and any amounts due from other partners are included in trade receivables. 74 Denbury Resources Inc. Notes to Consolidated Financial Statements Tertiary Injection Costs. Our tertiary operations are conducted in reservoirs that have already produced significant amounts of oil over many years; however, in accordance with the SEC rules and regulations for recording proved reserves, we cannot recognize proved reserves associated with enhanced recovery techniques, such as CO2 injection, until we can demonstrate production resulting from the tertiary process or unless the field is analogous to an existing flood. We capitalize, as a development cost, injection costs in fields that are in their development stage, which means we have not yet seen incremental oil production due to the CO2 injections (i.e., a production response). These capitalized development costs are included in our unevaluated property costs if there are not already proved tertiary reserves in that field. After we see a production response to the CO2 injections (i.e., the production stage), injection costs are expensed as incurred, and once proved reserves are recognized, previously deferred unevaluated development costs become subject to depletion. CO2 Properties We own and produce CO2 reserves, a non-hydrocarbon resource, that are used in our tertiary oil recovery operations on our own behalf and on behalf of other interest owners in enhanced recovery fields, with a portion sold to third-party industrial users. We record revenue from our sales of CO2 to third parties when it is produced and sold. Expenses related to the production of CO2 are allocated between volumes sold to third parties and volumes consumed internally that are directly related to our tertiary production. The expenses related to third-party sales are recorded in “CO2 discovery and operating expenses,” and the expenses related to internal use are recorded in “Lease operating expenses” in the Consolidated Statements of Operations or are capitalized as oil and natural gas properties in our Consolidated Balance Sheets, depending on the stage of the tertiary flood that is receiving the CO2 (see Tertiary Injection Costs above for further discussion). Costs incurred to search for CO2 are expensed as incurred until proved or probable reserves are established. Once proved or probable reserves are established, costs incurred to obtain those reserves are capitalized and classified as “CO2 properties” on our Consolidated Balance Sheets. Capitalized CO2 costs are aggregated by geologic formation and depleted on a unit-of- production basis over proved and probable reserves. Pipelines and Plants CO2 used in our tertiary floods is transported to our fields through CO2 pipelines. Costs of CO2 pipelines under construction are not depreciated until the pipelines are placed into service. Pipelines are depreciated on a straight-line basis over their estimated useful lives, which range from 15 to 50 years. Capitalized costs include $100.3 million of CO2 pipelines as of December 31, 2016, that were under construction and not subject to depreciation during 2016. We acquired the Riley Ridge Unit and the associated gas processing facility in 2010 and 2011 with the intent to separate for sale the natural gas and helium from the full well stream after construction of the gas processing facility was completed, and ultimately for the purpose of gaining a source of CO2 to utilize in flooding our fields in the Rocky Mountain region. Subsequently, issues arose related to contractor performance and design failure that caused significant delays and incremental costs to complete the facility. We placed the gas processing facility into service during the fourth quarter of 2013, and we were successful in running the facility for part of 2014 before additional issues arose related to optimal operation of the facility and sulfur build-up in the gas supply wells. In mid-2014, the gas processing facility was shut-in and to date remains shut-in. During this period, we have searched for and evaluated a number of potential options in an effort to remedy the existing issues, and our evaluation is still ongoing. Our current projected costs to remedy these issues and successfully operate the gas processing facility are not commercially reasonable investments based on a variety of factors, including (1) the substantial capital expenditures required to implement any corrective option, (2) current projected commodity prices, and (3) our projections of our EOR activities and their timing, resulting CO2 requirements and other assumptions. Due to the extended shut-in status of the Riley Ridge gas processing facility and our recently updated analysis of cost estimates and engineering options to remedy the existing issues, we reassessed the estimated useful life of the gas processing facility and related assets during the fourth quarter of 2016 and recorded accelerated depreciation of $591.0 million to “Depletion, depreciation, and amortization” in the Consolidated Statements of Operations, which includes $55.3 million of intangible assets assigned to helium production rights at Riley Ridge. We plan to continue engineering work and analysis to determine if there are alternative options to remediate the sulfur build-up in the gas supply wells and to assess our ability to reduce the costs thereof; however, the timing of completion and results of such analysis are currently uncertain. 75 Denbury Resources Inc. Notes to Consolidated Financial Statements Property and Equipment – Other Other property and equipment, which includes furniture and fixtures, vehicles, computer equipment and software, and capitalized leases, is depreciated principally on a straight-line basis over each asset’s estimated useful life. Vehicles and furniture and fixtures are generally depreciated over a useful life of five to ten years, and computer equipment and software are generally depreciated over a useful life of three to five years. Leasehold improvements are amortized over the shorter of the estimated useful life or the remaining lease term. Leased property meeting certain capital lease criteria is capitalized, and the present value of the related lease payments is recorded as a liability. Amortization of capitalized leased assets is computed using the straight-line method over the shorter of the estimated useful life or the lease term. Maintenance and repair costs that do not extend the useful life of the property or equipment are charged to expense as incurred. Goodwill and Other Intangible Assets Goodwill previously recorded on our Consolidated Balance Sheets represented the excess of the purchase price over the estimated fair value of the net assets acquired in the acquisition of businesses. Goodwill was not amortized; rather, it was tested for impairment annually during the fourth quarter or when events or changes in circumstances indicated that it was more likely than not the fair value of a reporting unit with goodwill was reduced below its carrying value. Because the fair value of the reporting unit (enterprise value) did not exceed the fair value of assets and liabilities, we recorded a goodwill impairment charge of $1.3 billion during 2015 to fully impair the carrying value of our goodwill. Our intangible asset subject to amortization primarily consists of amounts assigned in purchase accounting to a CO2 purchase contract with ConocoPhillips to offtake CO2 from the Lost Cabin gas plant in Wyoming and is included in our Consolidated Balance Sheets under the caption “Other assets.” We amortize the CO2 contract intangible asset on a straight- line basis over the contract term. Total amortization expense related to this asset was $2.3 million during the years ended December 31, 2016 and 2015. The following table summarizes the carrying value of our CO2 purchase contract intangible asset as of December 31, 2016 and 2015: In thousands Intangible asset value Accumulated amortization Net book value December 31, 2016 2015 $ $ 34,341 (8,203) 26,138 $ $ 34,341 (5,915) 28,426 As of December 31, 2016, our estimated amortization expense for our intangible asset subject to amortization over the next five years is as follows: In thousands 2017 2018 2019 2020 2021 $ 2,289 2,289 2,289 2,289 2,289 Impairment Assessment of Long-Lived Assets The portion of our capitalized CO2 costs related to CO2 reserves and CO2 pipelines that we estimate will be consumed in the process of producing our proved oil and natural gas reserves is included in the full cost pool ceiling test as a reduction 76 Denbury Resources Inc. Notes to Consolidated Financial Statements to future net revenues. The remaining net capitalized costs that are not included in the full cost pool ceiling test, and related intangible assets, are subject to long-lived asset impairment testing whenever events or changes in circumstances indicate that the carrying value may not be recoverable. We perform our long-lived asset impairment test by comparing the net carrying costs of our long-lived asset groups to the respective expected future undiscounted net cash flows that are supported by these long-lived assets which include production of our probable and possible oil and natural gas reserves. If the undiscounted net cash flows are below the net carrying costs for an asset group, we must record an impairment loss by the amount, if any, that net carrying costs exceed the fair value of the long-lived asset group. Due to an increase in cost estimates to correct and remedy the sulfur deposition issues at Riley Ridge provided in the results of preliminary engineering design efforts received late in 2016 and the potential impact on the utilization of Riley Ridge assets within the Rocky Mountain asset group, we performed a long-lived asset impairment test for the Rocky Mountain asset group during the fourth quarter of 2016. Significant assumptions impacting expected future undiscounted net cash flows include projections of future commodity prices, projections of estimated reserve quantities, projections of future rates of production, timing and amount of future development and operating costs, projected availability and cost of CO2, projected recovery factors of tertiary reserves and risk-adjustment factors applied to the net cash flows. The undiscounted net cash flows for our asset group exceeded the net carrying costs; thus, step two of the impairment test was not required and no impairment was recorded. Asset Retirement Obligations In general, our future asset retirement obligations relate to future costs associated with plugging and abandoning our oil, natural gas and CO2 wells, removing equipment and facilities from leased acreage, and returning land to its original condition. The fair value of a liability for an asset retirement obligation is recorded in the period in which it is incurred, discounted to its present value using our credit-adjusted-risk-free interest rate, and a corresponding amount capitalized by increasing the carrying amount of the related long-lived asset. The liability is accreted each period, and the capitalized cost is depreciated over the useful life of the related asset. Revisions to estimated retirement obligations will result in an adjustment to the related capitalized asset and corresponding liability. If the liability for an oil or natural gas well is settled for an amount other than the recorded amount, the difference is recorded to the full cost pool, unless significant. Asset retirement obligations are estimated at the present value of expected future net cash flows. We utilize unobservable inputs in the estimation of asset retirement obligations that include, but are not limited to, costs of labor and materials, profits on costs of labor and materials, the effect of inflation on estimated costs, and the discount rate. Accordingly, asset retirement obligations are considered a Level 3 measurement under the FASC Fair Value Measurement topic. Commodity Derivative Contracts We utilize oil and natural gas derivative contracts to mitigate our exposure to commodity price risk associated with our future oil and natural gas production. These derivative contracts have historically consisted of options, in the form of price floors, collars or three-way collars, fixed-price swaps and fixed-price swaps enhanced with a sold put. Our derivative financial instruments are recorded on the balance sheet as either an asset or a liability measured at fair value. We do not apply hedge accounting to our commodity derivative contracts; accordingly, changes in the fair value of these instruments are recognized in our Consolidated Statements of Operations in the period of change. Concentrations of Credit Risk Our financial instruments that are exposed to concentrations of credit risk consist primarily of cash equivalents, trade and accrued production receivables, and the derivative instruments discussed above. Our cash equivalents represent high-quality securities placed with various investment-grade institutions. This investment practice limits our exposure to concentrations of credit risk. Our trade and accrued production receivables are dispersed among various customers and purchasers; therefore, concentrations of credit risk are limited. We evaluate the credit ratings of our purchasers, and if customers are considered a credit risk, letters of credit are the primary security obtained to support lines of credit. We attempt to minimize our credit risk exposure to the counterparties of our oil and natural gas derivative contracts through formal credit policies, monitoring 77 Denbury Resources Inc. Notes to Consolidated Financial Statements procedures and diversification. All of our derivative contracts are with parties that are lenders under our senior secured bank credit facility (or affiliates of such lenders). There are no margin requirements with the counterparties of our derivative contracts. Oil and natural gas sales are made on a day-to-day basis or under short-term contracts at the current area market price. We would not expect the loss of any purchaser to have a material adverse effect upon our operations. For the year ended December 31, 2016, two purchasers accounted for 10% or more of our oil and natural gas revenues: Plains Marketing LP (20%) and Marathon Petroleum Company (14%). For the year ended December 31, 2015, two purchasers accounted for 10% or more of our oil and natural gas revenues: Marathon Petroleum Company (28%) and Plains Marketing LP (15%). For the year ended December 31, 2014, three purchasers accounted for 10% or more of our oil and natural gas revenues: Marathon Petroleum Company (31%), Plains Marketing LP (13%), and ConocoPhillips (12%). Revenue Recognition Revenue Recognition. Revenue is recognized at the time oil and natural gas is produced and sold. Any amounts due from purchasers of oil and natural gas are included in accrued production receivable. We follow the sales method of accounting for our oil and natural gas revenue, whereby we recognize revenue on oil or natural gas sold to our purchasers regardless of whether the sales are proportionate to our ownership in the property. A receivable or liability is recognized only to the extent that we have an imbalance on a specific property greater than the expected remaining proved reserves. As of December 31, 2016 and 2015, our aggregate oil and natural gas imbalances were not material to our consolidated financial statements. We recognize revenue and expenses of purchased producing properties at the time we assume effective control, commencing from either the closing or purchase agreement date, depending on the underlying terms and agreements. We follow the same methodology in reverse when we sell properties by recognizing revenue and expenses of the sold properties until the closing date. Income Taxes Income taxes are accounted for using the asset and liability method, under which deferred income taxes are recognized for the future tax effects of temporary differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities using the enacted statutory tax rates in effect at year end. The effect on deferred taxes for a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance for deferred tax assets is recorded when it is more likely than not that the benefit from the deferred tax asset will not be realized. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. Net Income (Loss) per Common Share Basic net income (loss) per common share is computed by dividing the net income (loss) attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per common share is calculated in the same manner, but includes the impact of potentially dilutive securities. Potentially dilutive securities consist of nonvested restricted stock, stock options, stock appreciation rights (“SARs”), and nonvested performance-based equity awards. For each of the three years in the period ended December 31, 2016, there were no adjustments to net income (loss) for purposes of calculating basic and diluted net income (loss) per common share. 78 Denbury Resources Inc. Notes to Consolidated Financial Statements The following is a reconciliation of the weighted average shares used in the basic and diluted net income (loss) per common share calculations for the periods indicated: In thousands Year Ended December 31, 2016 2015 2014 Basic weighted average common shares outstanding 373,859 348,802 348,962 Potentially dilutive securities Restricted stock, stock options, SARs and performance-based equity awards Diluted weighted average common shares outstanding — — 373,859 348,802 2,205 351,167 Basic weighted average common shares exclude shares of nonvested restricted stock. As these restricted shares vest, they will be included in the shares outstanding used to calculate basic net income (loss) per common share (although time- vesting restricted stock is issued and outstanding upon grant). For purposes of calculating diluted weighted average common shares during the year ended December 31, 2014, the nonvested restricted stock, stock options, SARs, and performance-based equity awards are included in the computation using the treasury stock method, with the deemed proceeds equal to the average unrecognized compensation during the period, the purchase price that the grantee will pay in the future for stock options, and any estimated future tax consequences recognized directly in equity. The following securities could potentially dilute earnings per share in the future, but were excluded from the computation of diluted net income (loss) per share, as their effect would have been antidilutive: In thousands Stock options and SARs Restricted stock and performance-based equity awards Environmental and Litigation Contingencies Year Ended December 31, 2016 2015 2014 6,427 5,816 9,619 3,867 4,775 417 The Company makes judgments and estimates in recording liabilities for contingencies such as environmental remediation or ongoing litigation. Liabilities are recorded when it is both probable that a loss has been incurred and such loss is reasonably estimable. Assessments of liabilities are based on information obtained from independent and in-house experts, loss experience in similar situations, actual costs incurred, and other case-by-case factors. Any related insurance recoveries are recognized in our financial statements during the period received or at the time receipt is determined to be virtually certain. Recent Accounting Pronouncements Recently Adopted Going Concern. In August 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-15, Presentation of Financial Statements – Going Concern (“ASU 2014-15”). ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in United States auditing standards. The amendments in this ASU are effective beginning in the fourth quarter of 2016, and for annual and interim periods thereafter. Effective December 31, 2016, we adopted ASU 2014-15. The adoption of ASU 2014-15 did not have an impact on our disclosures for the current period consolidated financial statements, as management has concluded there are no conditions or events raising substantial doubt about our ability to continue as a going concern within one year after these financial statements are being issued. Stock Compensation. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, and interim periods 79 Denbury Resources Inc. Notes to Consolidated Financial Statements within those fiscal years, and early adoption is permitted. The standard contains various amendments, each requiring a specific method of adoption, and designates whether each amendment should be adopted using a retrospective, modified retrospective, or prospective transition method. Effective January 1, 2016, we adopted ASU 2016-09. The amendments within ASU 2016-09 related to the timing of when excess tax benefits are recognized and accounting for forfeitures were adopted using a modified retrospective method. In accordance with this method, we recorded a cumulative-effect adjustment in our Consolidated Balance Sheet on January 1, 2016, relating to the timing of recognition of excess tax benefits, representing a $15.7 million reduction to beginning “Accumulated deficit” with the offset to “Deferred tax liabilities, net” ($14.8 million) and “Other current assets” ($0.8 million). We also recorded a cumulative-effect adjustment in our Consolidated Balance Sheet on January 1, 2016, to reflect actual forfeitures versus the previously-estimated forfeiture rate, representing a $0.4 million reduction to “Accumulated deficit” with the offset to “Paid-in capital in excess of par.” The amendments within ASU 2016-09 related to the recognition of excess tax benefits and tax shortfalls in the income statement and presentation of excess tax benefits on the statement of cash flows were adopted prospectively, with no adjustments made to prior periods. Income Taxes. In November 2015, the FASB issued ASU 2015-17, Income Taxes (“ASU 2015-17”). ASU 2015-17 simplifies the presentation of deferred income taxes and requires deferred tax assets and liabilities to be classified as noncurrent in the balance sheet. The amendments in this ASU are effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years, and early adoption is permitted. Entities can transition to the standard either retrospectively to each period presented or prospectively. Effective January 1, 2016, we adopted ASU 2015-17, which has been applied retrospectively for all comparative periods presented. Accordingly, current deferred tax assets of $1.5 million have been reclassified from “Deferred tax assets, net” to “Deferred tax liabilities, net” in our Consolidated Balance Sheet as of December 31, 2015. The adoption of ASU 2015-17 did not have an impact on our consolidated results of operations or cash flows. Debt Issuance Costs. In April 2015, the FASB issued ASU 2015-03, Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). ASU 2015-03 requires debt issuance costs related to a recognized debt liability to be presented as a direct reduction of the carrying amount of that debt in the balance sheet, consistent with the presentation of debt discounts. The amendments in this ASU are effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Entities are required to apply the guidance on a retrospective basis to each period presented as a change in accounting principle. In August 2015, the FASB issued ASU 2015-15, Interest – Imputation of Interest: Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-15”) which amends ASU 2015-03 to clarify the presentation and subsequent measurement of debt issuance costs associated with line of credit arrangements, such that entities may continue to apply current practice. Effective January 1, 2016, we adopted ASU 2015-03 and ASU 2015-15, which have been applied retrospectively for all comparative periods presented. Accordingly, debt issuance costs of $32.8 million associated with our previously issued senior subordinated notes have been reclassified from “Other assets” to “Long-term debt, net of current portion” in our Consolidated Balance Sheet as of December 31, 2015. The adoption of ASU 2015-03 and ASU 2015-15 did not have an impact on our consolidated results of operations or cash flows for any periods. Not Yet Adopted Leases. In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 amends the guidance for lease accounting to require lease assets and liabilities to be recognized on the balance sheet, along with additional disclosures regarding key leasing arrangements. The amendments in this ASU are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, and early adoption is permitted. Entities must adopt the standard using a modified retrospective transition and apply the guidance to the earliest comparative period presented, with certain practical expedients that entities may elect to apply. Management is currently assessing the impact the adoption of ASU 2016-02 will have on our consolidated financial statements. Revenue Recognition. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”). ASU 2014-09 amends the guidance for revenue recognition to replace numerous, industry-specific requirements. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU implements a five-step process for customer contract revenue recognition that focuses on transfer of control, as opposed to transfer of risk and rewards. The amendment also requires enhanced disclosures regarding the nature, amount, timing and uncertainty of revenues and cash flows arising from contracts with customers. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with 80 Denbury Resources Inc. Notes to Consolidated Financial Statements Customers (“ASU 2015-14”) which amends ASU 2014-09 and delays the effective date for public companies, such that the amendments in the ASU are effective for reporting periods beginning after December 15, 2017, and early adoption will be permitted for periods beginning after December 15, 2016. In March, April and May 2016, the FASB issued four additional ASUs which primarily clarified the implementation guidance on principal versus agent considerations, performance obligations and licensing, collectibility, presentation of sales taxes and other similar taxes collected from customers, and non-cash consideration. Entities can transition to the standard either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. We expect to adopt this standard using the modified retrospective method upon its effective date. Management is still evaluating the new guidance and has not yet determined the effect the standard will have on our consolidated financial statements. Note 2. Asset Retirement Obligations The following table summarizes the changes in our asset retirement obligations for the years ended December 31, 2016 and 2015: In thousands Beginning asset retirement obligations Liabilities incurred and assumed during period Revisions in estimated retirement obligations Liabilities settled and sold during period Accretion expense Ending asset retirement obligations Less: current asset retirement obligations (1) Long-term asset retirement obligations Year Ended December 31, 2016 2015 $ 145,696 $ 128,095 5,383 6,238 (19,878) 11,681 149,120 (2,313) 146,807 $ 9,628 5,238 (6,914) 9,649 145,696 (6,777) 138,919 $ (1) Included in “Accounts payable and accrued liabilities” in our Consolidated Balance Sheets. Liabilities assumed relate to minor acquisitions, with liabilities incurred generally relating to wells and facilities. We have escrow accounts that are legally restricted for certain of our asset retirement obligations. The balances of these escrow accounts were $39.3 million and $38.2 million as of December 31, 2016 and 2015, respectively. These balances are primarily invested in U.S. Treasury bonds, are recorded at amortized cost and are included in “Other assets” in our Consolidated Balance Sheets. The carrying value of these investments approximates their estimated fair market value as of December 31, 2016 and 2015. Note 3. Property and Equipment A summary of the unevaluated property costs excluded from oil and natural gas properties being amortized at December 31, 2016, and the year in which the costs were incurred follows: December 31, 2016 Costs Incurred During: In thousands 2016 2015 2014 2013 and Prior Total Property acquisition costs Exploration and development Capitalized interest Total $ $ 7,528 $ — $ 4,875 $ 592,184 $ 21,119 25,220 24,812 28,302 95,397 21,179 70,156 37,047 53,867 $ 53,114 $ 121,451 $ 699,387 $ 604,587 211,484 111,748 927,819 81 Denbury Resources Inc. Notes to Consolidated Financial Statements Our property acquisition costs for 2013 and prior were primarily related to the fair value allocated to the purchase of interests in the Cedar Creek Anticline (“CCA”), Hartzog Draw and Thompson fields, as well as CO2 tertiary potential at Conroe Field. Exploration and development costs shown as unevaluated properties are primarily associated with our tertiary oil fields that are under development but did not have proved reserves at December 31, 2016. The most significant development costs incurred during 2016, 2015 and 2014 relate to development in preparation for the CO2 floods at Webster and Grieve fields, with the more significant development costs incurred during 2013 and prior relating to development in preparation for the CO2 flood at Grieve Field. We have not yet recognized proved tertiary reserves in these fields. Costs are transferred into the amortization base on an ongoing basis as projects are evaluated and proved reserves established or impairment determined. We review the excluded properties for impairment at least annually. We currently estimate that evaluation of the majority of these properties and the inclusion of their costs in the amortization base is expected to be completed within five to ten years. Until we are able to determine whether there are any proved reserves attributable to the above costs, we are not able to assess the future impact on the amortization rate of the full cost pool. Note 4. Long-Term Debt The following long-term debt and capital lease obligations were outstanding as of December 31, 2016 and 2015: In thousands Senior Secured Bank Credit Agreement 9% Senior Secured Second Lien Notes due 2021 5½% Senior Subordinated Notes due 2022 Other Senior Subordinated Notes, including premium of $3 and $7, respectively Pipeline financings Capital lease obligations Total debt principal balance Future interest payable on 9% Senior Secured Second Lien Notes due 2021 (1) Issuance costs on senior secured second lien and senior subordinated notes Total debt, net of debt issuance costs Less: current maturities of long-term debt (1) Long-term debt and capital lease obligations December 31, 2016 2015 $ 301,000 $ 175,000 614,919 215,144 772,912 622,297 2,253 202,671 48,718 2,779,914 228,825 (15,641) 2,993,098 (83,366) 2,909,732 $ $ — 400,000 1,250,000 1,200,000 2,257 211,766 71,324 3,310,347 — (32,752) 3,277,595 (32,481) 3,245,114 (1) Future interest payable on our 9% Senior Secured Second Lien Notes due 2021 (the “2021 Senior Secured Notes”) represents most of the interest due over the term of this obligation, which has been accounted for as debt in accordance with FASC 470-60, Troubled Debt Restructuring by Debtors. Our current maturities of long-term debt as of December 31, 2016 include $50.3 million of future interest payable related to the 2021 Senior Secured Notes that is due within the next twelve months. See 2016 Senior Subordinated Notes Exchange below for further discussion. The ultimate parent company in our corporate structure, Denbury Resources Inc. (“DRI”), is the sole issuer of all of our outstanding 2021 Senior Secured Notes and senior subordinated notes. DRI has no independent assets or operations. Each of the subsidiary guarantors of such notes is 100% owned, directly or indirectly, by DRI, and the guarantees of the notes are full and unconditional and joint and several; any subsidiaries of DRI that are not subsidiary guarantors of such notes are minor subsidiaries. 82 Denbury Resources Inc. Notes to Consolidated Financial Statements Senior Secured Bank Credit Facility In December 2014, we entered into an Amended and Restated Credit Agreement with JPMorgan Chase Bank, N.A., as administrative agent, and other lenders party thereto (the “Bank Credit Agreement”). The Bank Credit Agreement is a senior secured revolving credit facility with a maturity date of December 9, 2019. Under the Bank Credit Agreement, letters of credit are available in an aggregate amount not to exceed $100 million, which may be increased at the sole discretion of the administrative agent, and short-term swingline loans are available in an aggregate amount not to exceed $25 million, each subject to the available commitments under the Bank Credit Agreement. The Bank Credit Agreement is guaranteed jointly and severally by each subsidiary of DRI that is 100% owned, directly or indirectly, by DRI and is secured by (1) a significant portion of our proved oil and natural gas properties held through DRI’s restricted subsidiaries; (2) the pledge of equity interests of such subsidiaries; (3) a pledge of commodity derivative agreements of DRI and such subsidiaries (as applicable); and (4) a pledge of deposit accounts, securities accounts and commodity accounts of DRI and such subsidiaries (as applicable). The Bank Credit Agreement limits our ability to, among other things, incur indebtedness; grant liens; engage in certain mergers, consolidations, liquidations and dissolutions; engage in sales of assets; make acquisitions and investments; make distributions and dividends; and enter into commodity derivative agreements, in each case subject to customary exceptions. As of December 31, 2016, the borrowing base and lender commitments for the revolving credit facility were $1.05 billion, and scheduled redeterminations of the borrowing base are to occur semiannually, with the next such redetermination being scheduled for May 2017. If our outstanding debt under the Bank Credit Agreement were to ever exceed the borrowing base, we would be required to repay the excess amount over a period not to exceed six months. In order to provide more flexibility in managing our balance sheet, the credit extended by our lenders, and continuing compliance with financial performance covenants in this low oil price environment, we entered into three amendments to the Bank Credit Agreement between May 2015 and April 2016 making the following modifications to the Bank Credit Agreement: • • • • • for 2016 and 2017, the maximum permitted ratio of consolidated total net debt to consolidated EBITDAX covenant was suspended and replaced by a maximum permitted ratio of consolidated senior secured debt to consolidated EBITDAX covenant of 3.0 to 1.0 (only debt under our Bank Credit Agreement is considered consolidated senior secured debt for purposes of this ratio); for 2016 and 2017, a new covenant was added to require a minimum permitted ratio of consolidated EBITDAX to consolidated interest charges of 1.25 to 1.0; allowing for the incurrence of up to $1.0 billion of junior lien debt (subject to customary requirements), with $385.1 million of future incurrence available as of December 31, 2016; limiting unrestricted cash and cash equivalents to $225 million if more than $250 million of borrowings are outstanding under the Bank Credit Agreement; and limiting the amount spent on repurchases or other redemptions of our senior subordinated notes to $225 million, with up to $148.3 million of this capacity remaining available as of December 31, 2016. Additionally, we are required to maintain a current ratio, as determined under the Bank Credit Agreement, of not less than 1.0 to 1.0. Beginning in the first quarter of 2018, the ratio of consolidated total net debt to consolidated EBITDAX covenant will be reinstated, utilizing an annualized EBITDAX amount for the first, second, and third quarters of 2018 and building to a trailing four quarters by the end of 2018, with the maximum permitted ratios being 6.0 to 1.0 for the first quarter ending March 31, 2018, 5.5 to 1.0 for the second quarter ending June 30, 2018, and 5.0 to 1.0 for the third and fourth quarters ending September 30 and December 31, 2018, and returning to 4.25 to 1.0 for the first quarter ending March 31, 2019. As of December 31, 2016, (1) loans under the Bank Credit Agreement were subject to varying rates of interest based on either (a) for ABR Loans, a base rate determined under the Bank Credit Agreement (the “ABR”) plus an applicable margin ranging from 1% to 2% per annum, or (b) for LIBOR Loans, the LIBOR rate plus an applicable margin ranging from 2% to 3% per annum (capitalized terms as defined in the Bank Credit Agreement) and (2) the undrawn portion of the aggregate lender commitments under the Bank Credit Agreement was subject to a commitment fee of 0.50%. As of December 31, 2016, we were in compliance with all debt covenants under the Bank Credit Agreement. The weighted average interest rate on borrowings outstanding under the Bank Credit Agreement was 3.0% and 2.3% as of December 31, 2016 and 2015, respectively. 83 Denbury Resources Inc. Notes to Consolidated Financial Statements The above description of our Bank Credit Agreement financial performance covenants and the changes provided for within the three amendments are qualified by the express language and defined terms contained in the Bank Credit Agreement, the First Amendment to the Bank Credit Agreement dated May 4, 2015, the Second Amendment to the Bank Credit Agreement dated February 17, 2016, and the Third Amendment to the Bank Credit Agreement dated April 18, 2016, each of which are filed as exhibits to our periodic reports filed with the SEC. 2016 Senior Subordinated Notes Exchange During May 2016, we entered into privately negotiated agreements to exchange a total of $1,057.8 million of our existing senior subordinated notes for $614.9 million principal amount of our 2021 Senior Secured Notes plus 40.7 million shares of Denbury common stock, resulting in a net reduction from these exchanges of $442.9 million in our debt principal. The Senior Subordinated Notes due 2021 (the “2021 exchanged notes consisted of $175.1 million principal amount of our Notes”), $411.0 million principal amount of our 5½% Senior Subordinated Notes due 2022 (the “2022 Notes”), and $471.7 million principal amount of our Senior Subordinated Notes due 2023 (the “2023 Notes”). In accordance with FASC 470-60, the exchanges were accounted for as a troubled debt restructuring due to the level of concession provided by our senior subordinated note holders. Under this guidance, future interest applicable to the 2021 Senior Secured Notes is recorded as debt up to the point that the principal and future interest of the new notes is equal to the principal amount of the extinguished notes, rather than recognizing a gain on extinguishment for this amount. As a result, $254.7 million of future interest on the 2021 Senior Secured Notes was recorded as debt, which will be reduced as semiannual interest payments are made, with the remaining $22.8 million of future interest to be recognized as interest expense over the term of these notes. Therefore, future interest expense reflected in our Consolidated Statements of Operations on the 2021 Senior Secured Notes will be significantly lower than the actual cash interest payments. In addition, we recognized a gain of $12.0 million as a result of this debt exchange during the year ended December 31, 2016, which is included in “Loss (gain) on debt extinguishment” in the accompanying Consolidated Statements of Operations. 9% Senior Secured Second Lien Notes due 2021 In May 2016, we issued $614.9 million of 2021 Senior Secured Notes. The 2021 Senior Secured Notes, which bear interest at a rate of 9% per annum, were issued at par in connection with privately negotiated exchanges with a limited number of holders of $1,057.8 million of existing senior subordinated notes (see 2016 Senior Subordinated Notes Exchange above). The 2021 Senior Secured Notes mature on May 15, 2021, and interest is payable semiannually in arrears on May 15 and November 15 of each year, beginning in November 2016. We may redeem the 2021 Senior Secured Notes in whole or in part at our option beginning December 15, 2018, at a redemption price of 109% of the principal amount, and at declining redemption prices thereafter, as specified in the indenture governing the 2021 Senior Secured Notes (the “Indenture”). Prior to December 15, 2018, we may at our option redeem up to an aggregate of 35% of the principal amount of the 2021 Senior Secured Notes at a price of 109% of par with the proceeds of certain equity offerings. In addition, at any time prior to December 15, 2018, we may redeem the 2021 Senior Secured Notes in whole or in part at a price equal to 100% of the principal amount plus a “make-whole” premium and accrued and unpaid interest. The 2021 Senior Secured Notes are not subject to any sinking fund requirements. The Indenture contains customary covenants that restrict our ability and the ability of our restricted subsidiaries to (1) incur additional debt; (2) make investments; (3) create liens on our assets or the assets of our restricted subsidiaries; (4) create limitations on the ability of our restricted subsidiaries to pay dividends or make other payments to DRI or other restricted subsidiaries; (5) engage in transactions with our affiliates; (6) transfer or sell assets or subsidiary stock; (7) consolidate, merge or transfer all or substantially all of our assets and the assets of our restricted subsidiaries; and (8) make restricted payments (which includes paying dividends on our common stock or redeeming, repurchasing or retiring such stock or subordinated debt (including existing senior subordinated notes)), provided that in certain circumstances we may make unlimited restricted payments so long as we maintain a ratio of total debt to EBITDA (as defined in the Indenture) not to exceed 2.5 to 1.0 (both before and after giving effect to any restricted payment). The 2021 Senior Secured Notes are guaranteed jointly and severally by our subsidiaries representing substantially all of our assets, operations and income and are secured by second-priority liens on substantially all of the assets that secure the 84 Denbury Resources Inc. Notes to Consolidated Financial Statements Bank Credit Agreement, which second-priority liens are contractually subordinated to liens that secure our Bank Credit Agreement and any future additional priority lien debt. Senior Subordinated Notes Senior Subordinated Notes due 2021. In February 2011, we issued $400 million of 2021 Notes. The 2021 Notes, which bear interest at a rate of 6.375% per annum, were sold at par. The 2021 Notes mature on August 15, 2021, and interest is payable on February 15 and August 15 of each year. We may redeem the 2021 Notes in whole or in part at our option beginning August 15, 2016, at a redemption price of 103.188% of the principal amount, and at declining redemption prices thereafter, as specified in the indenture. 5½% Senior Subordinated Notes due 2022. In April 2014, we issued $1.25 billion of 2022 Notes. The 2022 Notes, which bear interest at a rate of 5.5% per annum, were sold at par. The net proceeds, after issuance costs, of $1.23 billion were used to repurchase or redeem our outstanding 8¼% Senior Subordinated Notes due 2020 (the “2020 Notes”), which were issued in 2010 (see 2014 Repurchase and Redemption of 8¼% Senior Subordinated Notes due 2020 below), and to pay down a portion of outstanding borrowings under our previous Bank Credit Agreement. The 2022 Notes mature on May 1, 2022, and interest is payable on May 1 and November 1 of each year. We may redeem the 2022 Notes in whole or in part at our option beginning May 1, 2017, at a redemption price of 104.125% of the principal amount, and at declining redemption prices thereafter, as specified in the indenture. Prior to May 1, 2017, we may at our option redeem up to an aggregate of 35% of the principal amount of the 2022 Notes at a price of 105.5% of par with the proceeds of certain equity offerings. In addition, at any time prior to May 1, 2017, we may redeem 100% of the principal amount of the 2022 Notes at a price equal to 100% of the principal amounts plus a “make-whole” premium and accrued and unpaid interest. The 2022 Notes are not subject to any sinking fund requirements. Senior Subordinated Notes due 2023. In February 2013, we issued $1.2 billion of 2023 Notes. The 2023 Notes, which bear interest at a rate of 4.625% per annum, were sold at par. The 2023 Notes mature on July 15, 2023, and interest is payable on January 15 and July 15 of each year. We may redeem the 2023 Notes in whole or in part at our option beginning January 15, 2018, at a redemption price of 102.313% of the principal amount, and at declining redemption prices thereafter, as specified in the indenture. In addition, at any time prior to January 15, 2018, we may redeem 100% of the principal amount of the 2023 Notes at a redemption price equal to 100% of the principal amount plus a “make-whole” premium and accrued and unpaid interest. The 2023 Notes are not subject to any sinking fund requirements. Restrictive Covenants in Indentures for Senior Subordinated Notes. Each of the indentures for the 2021 Notes, 2022 Notes and 2023 Notes contains certain covenants that are generally consistent and that restrict our ability and the ability of our restricted subsidiaries to take or permit certain actions, including restrictions on our ability and the ability of our restricted subsidiaries to (1) incur additional debt; (2) make investments; (3) create liens on our assets or the assets of our restricted subsidiaries; (4) create restrictions on the ability of our restricted subsidiaries to pay dividends or make other payments to DRI or other restricted subsidiaries; (5) engage in transactions with our affiliates; (6) transfer or sell assets or subsidiary stock; (7) consolidate, merge or transfer all or substantially all of our assets and the assets of our restricted subsidiaries; and (8) make restricted payments (which includes paying dividends on our common stock or redeeming, repurchasing or retiring such stock or subordinated debt), provided that the restricted payments covenant in the indentures for the 2022 and 2023 Notes (the “2022 and 2023 Indentures”) permits us in certain circumstances to make unlimited restricted payments so long as we maintain a ratio of total debt to EBITDA (both as defined in the 2022 and 2023 Indentures) not to exceed 2.5 to 1.0 (both before and after giving effect to any restricted payment), although we will not be able to realize the practical benefit of the restricted payment covenant flexibility in the 2022 and 2023 Indentures until the 2021 Notes have been redeemed or retired. As of December 31, 2016, we were in compliance with all debt covenants under the indentures related to our senior subordinated notes. 2016 Repurchases of Senior Subordinated Notes. During 2016, we repurchased a total of $181.9 million of our outstanding long-term indebtedness, consisting of $9.8 million principal amount of our 2021 Notes, $66.1 million principal amount of our 2022 Notes, and $106.0 million principal amount of our 2023 Notes in open-market transactions for a total purchase price of $76.7 million, excluding accrued interest. In connection with these series of transactions, we recognized a $103.1 million gain on extinguishment, net of unamortized debt issuance costs written off, during the year ended December 31, 85 Denbury Resources Inc. Notes to Consolidated Financial Statements 2016. As of February 22, 2017, under the Bank Credit Agreement, up to an additional $148.3 million may be spent on repurchases or other redemptions of our senior subordinated notes. 2014 Repurchase and Redemption of 8¼% Senior Subordinated Notes due 2020. Pursuant to a cash tender, during 2014, we repurchased $996.3 million in principal of our 2020 Notes. We recognized a $113.9 million loss associated with the debt repurchases during the second quarter of 2014, which loss consists of both premium payments made to repurchase or redeem the 2020 Notes and the elimination of unamortized debt issuance costs related to these notes. The loss is included in our Consolidated Statements of Operations under the caption “Loss (gain) on debt extinguishment,” and premium payments made to repurchase the notes are classified as a financing cash outflow on our Consolidated Statements of Cash Flows under the caption “Premium paid on repayment of senior subordinated notes.” Pipeline Financings In May 2008, we closed two transactions with Genesis Energy, L.P. (“Genesis”) involving two of our pipelines. The NEJD Pipeline system included a 20-year financing lease, and the Free State Pipeline included a long-term transportation service agreement. These transactions are both accounted for as financing leases. Debt Issuance Costs In connection with the issuance of our outstanding long-term debt, we have incurred debt issuance costs, which are being amortized to interest expense using the straight line or effective interest method over the term of each related facility or borrowing. Remaining unamortized debt issuance costs were $24.7 million and $49.8 million at December 31, 2016 and 2015, respectively. Issuance costs associated with our Bank Credit Agreement are included in “Other assets” in our Consolidated Balance Sheets, and issuance costs associated with our senior secured second lien and senior subordinated notes are included as a reduction of “Long-term debt, net of current portion” in our Consolidated Balance Sheets in accordance with the adoption of ASU 2015-03 (see Note 1, Significant Accounting Policies – Recent Accounting Pronouncements – Recently Adopted – Debt Issuance Costs above). Indebtedness Repayment Schedule At December 31, 2016, our indebtedness, including our capital and financing lease obligations but excluding the discount and premium on our senior subordinated debt, is payable over the next five years and thereafter as follows: In thousands 2017 2018 2019 2020 2021 Thereafter Total indebtedness $ $ 33,014 33,966 328,407 16,145 845,422 1,522,957 2,779,911 86 Denbury Resources Inc.

Income Taxes Our income tax provision (benefit) is as follows: In thousands Current income tax expense (benefit) Federal State Total current income tax benefit Deferred income tax expense (benefit) Federal State Year Ended December 31, 2016 2015 2014 $ — $ (785) (785) (8,515) $ 160 (8,355) (42,500) (407) (42,907) (521,519) (21,866) (543,385) (544,170) $ (1,853,517) (78,662) (1,932,179) (1,940,534) $ 400,544 29,429 429,973 387,066 Total deferred income tax expense (benefit) Total income tax expense (benefit) $ At December 31, 2016, we had tax-effected federal net operating loss carryforwards (“NOLs”) totaling $27.1 million, state NOLs totaling $42.6 million (before provision for valuation allowance), an estimated $51.1 million of enhanced oil recovery credits to carry forward related to our tertiary operations, an estimated $21.6 million of research and development credits, and $41.1 million of alternative minimum tax credits. Our state NOLs expire in various years, starting in 2019, although most do not begin to expire until 2036. Our enhanced oil recovery credits and research and development credits will begin to expire in 2023 and 2031, respectively. Deferred income taxes reflect the available tax carryforwards and the temporary differences based on tax laws and statutory rates in effect at the December 31, 2016 and 2015 balance sheet dates. As of December 31, 2016, we had $36.5 million of deferred tax assets associated with State of Louisiana net operating losses. As the result of falling commodity prices, combined with a tax law enacted in the State of Louisiana effective June 30, 2015, which limits a company’s utilization of certain deductions, including our net operating loss carryforwards, we recognized tax valuation allowances totaling $33.6 million during 2015 and an additional $2.9 million during 2016, which reduced the carrying value of our deferred tax assets. The valuation allowances will remain until the realization of future deferred tax benefits are more likely than not to become utilized. As of December 31, 2016, we had an unrecognized tax benefit of $5.4 million related to an uncertain tax position. The unrecognized tax benefit was recorded during 2015 as a direct reduction of the associated deferred tax asset and, if recognized, would not materially affect our annual effective tax rate. The tax benefit from an uncertain tax position will only be recognized if it is more likely than not that the tax position will be sustained upon examination by the taxing authorities, based upon the technical merits of the position. We currently do not expect a material change to the uncertain tax position within the next 12 months. Our policy is to recognize penalties and interest related to uncertain tax positions in income tax expense; however, no such amounts were accrued related to the uncertain tax position as of December 31, 2016. In connection with the privately negotiated agreements to exchange a portion of our existing senior subordinated notes for 2021 Senior Secured Notes, we realized a tax gain due to the concession extended by our note holders during the second quarter of 2016. This tax gain was offset by net operating losses and other deferred tax asset attributes. 87 Denbury Resources Inc. Notes to Consolidated Financial Statements Significant components of our deferred tax assets and liabilities as of December 31, 2016 and 2015 are as follows: In thousands Deferred tax assets Loss carryforwards – federal Loss carryforwards – state Tax credit carryover Business credit carryforwards Derivative contracts Stock-based compensation Unrecognized gain and original issue discount on debt exchange Other Valuation allowance Total deferred tax assets Deferred tax liabilities Property and equipment Derivative contracts Other Total deferred tax liabilities Total net deferred tax liability December 31, 2016 2015 $ 27,078 $ 42,625 41,132 72,748 27,261 10,306 106,321 38,834 (36,510) 329,795 52,580 37,175 34,837 70,452 — 23,468 — 34,236 (33,600) 219,148 (619,923) — (3,750) (623,673) (293,878) $ (1,004,330) (50,081) (16,826) (1,071,237) (852,089) $ Our reconciliation of income tax expense computed by applying the U.S. federal statutory rate and the reported effective tax rate on income from continuing operations is as follows: In thousands Income tax provision (benefit) calculated using the federal statutory income tax rate State income taxes, net of federal income tax benefit Impairment of goodwill with no related tax basis Tax shortfall on stock-based compensation deduction Valuation allowance Other Total income tax expense (benefit) Year Ended December 31, 2016 2015 2014 $ $ (532,121) $ (25,351) — 9,557 2,910 835 (544,170) $ (2,214,094) $ (117,624) 363,666 — 33,600 (6,082) (1,940,534) $ 357,895 25,368 — — — 3,803 387,066 We file consolidated and separate income tax returns in the U.S. federal jurisdiction and in many state jurisdictions. The statutes of limitation for our income tax returns for tax years ending prior to 2011 have lapsed and therefore are not available for examination by respective taxing authorities. We have not paid any significant interest or penalties associated with our income taxes. 88 Denbury Resources Inc. Notes to Consolidated Financial Statements Note 6. Stockholders’ Equity 401(k) Plan We offer a 401(k) plan to which employees may contribute earnings subject to IRS limitations. We match 100% of an employee’s contribution, up to 6% of compensation, as defined by the plan, which is vested immediately. During 2016, 2015 and 2014, our matching contributions to the 401(k) plan were approximately $7.7 million, $10.1 million and $9.9 million, respectively. 2015 Retirement of Treasury Stock During the year ended December 31, 2015, we retired 60.0 million shares of existing treasury stock, with a carrying value of $884.1 million, acquired principally through our stock repurchase program. These retired shares are now included in the pool of authorized but unissued shares. Our accounting policy upon the retirement of treasury stock is to deduct its par value from common stock and reduce additional paid-in capital by the excess amount of treasury stock retired. Dividends Declared During 2015 During the first three quarters of 2015, the Company’s Board of Directors declared quarterly cash dividends of $0.0625 per common share, with dividends totaling $65.4 million paid to stockholders during the year ending December 31, 2015. In September 2015, in light of the continuing low oil price environment and our desire to maintain our financial strength and flexibility, the Company’s Board of Directors suspended our quarterly cash dividend.

Stock Compensation The Amended and Restated 2004 Omnibus Stock and Incentive Plan, amended and restated as of May 24, 2016 (the “2004 Plan”), is an incentive plan that provides for the issuance of incentive and non-qualified stock options, restricted stock awards, restricted stock units, SARs settled in stock, and performance-based awards to officers, employees and directors. Since the 2004 Plan’s inception, awards covering a total of 44.5 million shares of common stock have been authorized for issuance pursuant to the 2004 Plan. As of December 31, 2016, 9.7 million shares were available under the 2004 Plan for future issuance of awards, all of which could be issued in the form of restricted stock or performance-based awards. Our incentive compensation program is administered by the Compensation Committee of our Board of Directors. The 2004 Plan was last approved by our stockholders in May 2016 and will expire in May 2026. Stock-based compensation expense associated with our field employees is included in “Lease operating expenses,” while such expense associated with non-field employees is included in “General and administrative expenses” in the Consolidated Statements of Operations. Stock-based compensation associated with our employees involved in exploration and drilling activities is capitalized as part of “Oil and natural gas properties” in the Consolidated Balance Sheets. Effective January 1, 2016, with the adoption of ASU 2016-09, we made an accounting policy election to account for forfeitures as they occur, versus the previously-estimated forfeiture rate. 89 Denbury Resources Inc. Notes to Consolidated Financial Statements Stock-based compensation costs for the years ended December 31, 2016, 2015 and 2014, are as follows: In thousands Stock-based compensation expensed General and administrative expenses Lease operating expenses Total stock-based compensation expensed Stock-based compensation capitalized Total cost of stock-based compensation arrangements Income tax benefit recognized for stock-based compensation arrangements Stock Options and SARs Year Ended December 31, 2016 2015 2014 14,359 $ 27,995 $ 636 14,995 6,047 2,609 30,604 8,681 21,042 $ 39,285 $ 27,789 2,724 30,513 9,019 39,532 5,698 $ 11,630 $ 11,595 $ $ $ Prior to January 1, 2006, we granted incentive and non-qualified stock options to our employees. Effective January 1, 2006, we replaced the use of stock options for employees with SARs settled in stock, as SARs are less dilutive to our stockholders while providing an employee with essentially the same economic benefits as stock options. As of December 31, 2015, we also discontinued the issuance of SARs. The stock options and SARs generally become exercisable over a three-year vesting period, with the specific terms of vesting determined at the time of grant based on guidelines established by the Compensation Committee of the Board of Directors. The stock options and SARs expire over terms not to exceed 10 years from the date of grant, 90 days after termination of employment, 90 days or one year after permanent disability, depending on the award, or one year after the death of the optionee. As of December 31, 2015, all outstanding options had expired. The stock options and SARs were granted with a strike price equal to the fair market value at the time of grant, which is generally defined as the closing price on the NYSE on the date of grant. The fair value of each SAR award is estimated on the date of grant using the Black-Scholes option pricing model with the assumptions noted in the following table. The risk-free rate for periods within the contractual life of the SAR is based on the U.S. Treasury yield curve in effect at the time of grant. The expected life of SARs granted was derived from examination of our historical SAR grants and subsequent exercises. The contractual terms (cliff vesting and graded vesting) are evaluated separately for the expected life, as the exercise behavior for each is different. Expected volatilities are based on the historical volatility of our common stock. There were no SAR awards granted in 2016.

Holders of non-performance-based restricted stock awards have the rights of owning non-restricted stock (including voting rights) except that the holders are not entitled to delivery of a portion thereof until certain requirements are met. Beginning in 2014, non-performance-based restricted stock awards provide the holders with forfeitable dividend equivalent rights which vests with the underlying shares. Non-performance-based restricted stock vests over a three-year vesting period, with the specific terms of vesting determined at the time of grant. As of December 31, 2016, there was $26.1 million of unrecognized compensation expense related to nonvested non- performance-based restricted stock grants. This unrecognized compensation cost is expected to be recognized over a weighted- average period of 2.1 years.

Notes to Consolidated Financial Statements A summary of the status of our nonvested non-performance-based restricted stock grants issued, and the changes during the year ended December 31, 2016, is presented below: Nonvested at December 31, 2015 Granted Vested Forfeited Nonvested at December 31, 2016 Performance-Based Equity Awards Number of Shares 5,589,687 $ 7,569,553 (2,906,465) (511,990) 9,740,785 Weighted Average Grant-Date Fair Value 9.27 3.23 10.44 7.09 4.34 Annually, the Compensation Committee of the Board of Directors grants performance-based equity awards to Denbury’s officers. Performance-based awards generally vest over 1.25 to 3.25 years, and the number of performance-based shares earned (and eligible to vest) during the performance period will depend upon: (1) our level of success in achieving specifically identified performance targets (“Performance-Based Operational Awards”) and (2) performance of our stock relative to that of a designated peer group (“Performance-Based TSR Awards”). Generally, one-half of the maximum number of shares that could be earned under the performance-based awards will be earned for performance at the designated target levels (100% target vesting levels) or upon any earlier change of control, and twice the target number of shares will be earned if the maximum target levels are met (200% of target vesting levels). With respect to the 2016 performance-based equity awards, any amounts earned above the 100% target levels will be payable in cash, rather than in shares of Denbury stock, in order to conserve available shares under the Plan. If performance is below the designated minimum levels, no performance-based shares will be earned. Performance-Based Operational Awards are valued using the fair market value of Denbury stock on the grant date, and Performance-Based TSR Awards are valued using a Monte Carlo simulation. During 2016 and 2015, we granted performance-based equity awards to our officers. As of December 31, 2016, there was $2.2 million of unrecognized compensation expense related to nonvested performance-based equity awards. This unrecognized compensation cost is expected to be recognized over a weighted-average period of 1.6 years. The range of assumptions used in the Monte Carlo simulation valuation approach for Performance-Based TSR Awards (presented at the target level) are as follows: Weighted average fair value of Performance-Based TSR Awards granted $ Risk-free interest rate Expected life Expected volatility Dividend yield Year Ended December 31, 2016 2015 2014 1.78 $ 1.31% 7.59 $ 19.81 0.96% 0.80% 3.0 years 3.0 years 3.0 years 57.2% —% 33.6% 3.42% 39.4% 2.50% 92 Denbury Resources Inc.

Commodity Derivative Contracts We do not apply hedge accounting treatment to our oil and natural gas derivative contracts; therefore, the changes in the fair values of these instruments are recognized in income in the period of change. These fair value changes, along with the settlements of expired contracts, are shown under “Commodity derivatives expense (income)” in our Consolidated Statements of Operations. Historically, we have entered into various oil and natural gas derivative contracts to provide an economic hedge of our exposure to commodity price risk associated with anticipated future oil and natural gas production and to provide more certainty to our future cash flows. We do not hold or issue derivative financial instruments for trading purposes. Generally, these contracts have consisted of various combinations of price floors, collars, three-way collars, fixed-price swaps and fixed-price swaps enhanced with a sold put. The production that we hedge has varied from year to year depending on our levels of debt, financial strength and expectation of future commodity prices. We manage and control market and counterparty credit risk through established internal control procedures that are reviewed on an ongoing basis. We attempt to minimize credit risk exposure to counterparties through formal credit policies, monitoring procedures and diversification, and all of our commodity derivative contracts are with parties that are lenders under our Bank Credit Agreement (or affiliates of such lenders). As of December 31, 2016, all of our outstanding derivative contracts were subject to enforceable master netting arrangements whereby payables on those contracts can be offset against receivables from separate derivative contracts with the same counterparty. It is our policy to classify derivative assets and liabilities on a gross basis on our balance sheets, even if the contracts are subject to enforceable master netting arrangements. 93 Denbury Resources Inc. Notes to Consolidated Financial Statements The following table summarizes our commodity derivative contracts as of December 31, 2016, none of which are classified as hedging instruments in accordance with the FASC Derivatives and Hedging topic: Index Price Months Oil Contracts: 2017 Fixed-Price Swaps Jan – Mar Jan – Mar NYMEX LLS Apr – June NYMEX Apr – June 2017 Collars LLS Jan – Mar Jan – Mar NYMEX LLS Oct – Dec NYMEX 2017 Three-Way Collars (2) July – Sept NYMEX July – Sept LLS Oct – Dec NYMEX Oct – Dec LLS Volume (Barrels per day) Contract Prices ($/Bbl) Weighted Average Price Range (1) Swap Sold Put Floor Ceiling 22,000 10,000 22,000 7,000 4,000 3,000 1,000 13,500 2,000 10,000 1,000 $ $ $ 41.15 – 42.35 – 41.20 – 42.65 – 40.00 – 40.00 – 40.00 – 40.00 – 41.00 – 40.00 – 41.00 – 45.45 $ 42.67 $ — $ — $ 46.15 46.50 46.65 55.40 57.35 70.00 43.77 43.99 45.35 — — — — — — $ — $ — — — $ — — $ 40.00 40.00 40.00 70.25 $ — $ 30.00 $ 40.00 $ 69.25 70.20 70.25 — — — 31.00 30.00 31.00 41.00 40.00 41.00 — — — — 54.80 57.23 70.00 69.13 69.25 69.64 70.25 (1) Ranges presented for fixed-price swaps represent the lowest and highest fixed prices of all open contracts for the period presented. For collars and three-way collars, ranges represent the lowest floor price and highest ceiling price for all open contracts for the period presented. (2) A three-way collar is a costless collar contract combined with a sold put feature (at a lower price) with the same counterparty. The value received for the sold put is used to enhance the contracted floor and ceiling price of the related collar. At the contract settlement date, (1) if the index price is higher than the ceiling price, we pay the counterparty the difference between the index price and ceiling price for the contracted volumes, (2) if the index price is between the floor and ceiling price, no settlements occur, (3) if the index price is lower than the floor price but at or above the sold put price, the counterparty pays us the difference between the index price and the floor price for the contracted volumes and (4) if the index price is lower than the sold put price, the counterparty pays us the difference between the floor price and the sold put price for the contracted volumes. Note 9. Fair Value Measurements The FASC Fair Value Measurement topic defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (often referred to as the “exit price”). We utilize market data or assumptions that market participants would use in pricing the asset or liability, including assumptions about risk and the risks inherent in the inputs to the valuation technique. These inputs can be readily observable, market corroborated or generally unobservable. We primarily apply the income approach for recurring fair value measurements and endeavor to utilize the best available information. Accordingly, we utilize valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. We are able to classify fair value balances based on the observability of those inputs. The FASC establishes a fair value hierarchy that prioritizes the inputs used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). 94 Denbury Resources Inc. Notes to Consolidated Financial Statements The three levels of the fair value hierarchy are as follows: • Level 1 – Quoted prices in active markets for identical assets or liabilities as of the reporting date. • Level 2 – Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reported date. Level 2 includes those financial instruments that are valued using models or other valuation methodologies. Instruments in this category include non-exchange-traded oil derivatives that are based on NYMEX pricing and fixed-price swaps that are based on regional pricing other than NYMEX (e.g., Light Louisiana Sweet). Our costless collars and the sold put features of our three-way collars are valued using the Black-Scholes model, an industry standard option valuation model that takes into account inputs such as contractual prices for the underlying instruments, maturity, quoted forward prices for commodities, interest rates, volatility factors and credit worthiness, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace. • Level 3 – Pricing inputs include significant inputs that are generally less observable. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value. At December 31, 2016, instruments in this category include non-exchange-traded costless collars and three-way collars that are based on regional pricing other than NYMEX (e.g., Light Louisiana Sweet). The valuation models utilized for costless collars and three-way collars are consistent with the methodologies described above; however, the implied volatilities utilized in the valuation of Level 3 instruments are developed using a benchmark, which is considered a significant unobservable input. An increase or decrease of 100 basis points in the implied volatility inputs utilized in our fair value measurement would result in a change of approximately $50 thousand in the fair value of these instruments as of December 31, 2016. We adjust the valuations from the valuation model for nonperformance risk, using our estimate of the counterparty’s credit quality for asset positions and our credit quality for liability positions. We use multiple sources of third-party credit data in determining counterparty nonperformance risk, including credit default swaps. The following table sets forth by level within the fair value hierarchy our financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2016 and 2015: In thousands December 31, 2016 Liabilities Oil derivative contracts – current Total Liabilities December 31, 2015 Assets Oil derivative contracts – current Total Assets Fair Value Measurements Using: Quoted Prices in Active Markets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) Total $ $ $ $ — $ — $ 68,753 68,753 — $ — $ 90,012 90,012 $ $ $ $ 526 526 52,834 52,834 $ $ $ $ 69,279 69,279 142,846 142,846 Since we do not apply hedge accounting for our commodity derivative contracts, any gains and losses on our assets and liabilities are included in “Commodity derivatives expense (income)” in the accompanying Consolidated Statements of Operations. 95 Denbury Resources Inc.

We obtain and ensure the appropriateness of the significant inputs to the calculation, including contractual prices for the underlying instruments, maturity, forward prices for commodities, interest rates, volatility factors and credit worthiness, and the fair value estimate is prepared and reviewed on a quarterly basis. The following table details fair value inputs related to implied volatilities utilized in the valuation of our Level 3 oil derivative contracts: Fair Value at 12/31/2016 (in thousands) Valuation Technique Unobservable Input Range Oil derivative contracts $ (526) Discounted cash flow / Black-Scholes Volatility of Light Louisiana Sweet for settlement periods beginning after December 31, 2016 15.3% – 38.4% Other Fair Value Measurements The carrying value of our loans under our Bank Credit Agreement approximate fair value, as they are subject to short- term floating interest rates that approximate the rates available to us for those periods. We use a market approach to determine the fair value of our fixed-rate long-term debt using observable market data. The fair values of our senior secured second lien notes and senior subordinated notes are based on quoted market prices. The estimated fair value of the principal amount of our debt as of December 31, 2016 and 2015, excluding pipeline financing and capital lease obligations, was $2,327.8 million and $1,119.0 million, respectively, which increase is primarily driven by an increase in quoted market prices. We have other financial instruments consisting primarily of cash, cash equivalents, short-term receivables and payables that approximate fair value due to the nature of the instrument and the relatively short maturities. 96 Denbury Resources Inc. Notes to Consolidated Financial Statements Note 10. Commitments and Contingencies Leases We lease office space, equipment and vehicles that have non-cancelable lease terms. Currently, our outstanding leases have terms up to 9 years. We have subleased part of the office space included in our operating leases for which we received rental payments. The following table summarizes operating lease payments paid and sublease rentals received during the periods indicated: In thousands Operating lease payments Sublease rental receipts Year Ended December 31, 2016 2015 2014 $ 22,744 $ 29,403 $ 3,074 3,698 43,333 2,347 The following tables summarize by year the remaining non-cancelable future payments under our leases as of December 31, 2016: In thousands 2017 2018 2019 2020 2021 Thereafter Total minimum lease payments Less: Amount representing interest Present value of minimum lease payments In thousands 2017 2018 2019 2020 2021 Thereafter Total minimum lease payments Pipeline and Capital Leases 48,579 48,139 40,215 27,872 26,092 165,170 356,067 (104,678) 251,389 Operating Leases 10,965 11,154 10,574 9,734 9,996 38,549 90,972 $ $ $ $ In addition, we expect to receive approximately $7.8 million for 2017 through 2019 under our sublease agreements. Commitments We have entered into long-term commitments to purchase CO2 that are either non-cancelable or cancelable only upon the occurrence of specified future events. The commitments continue for up to 16 years. The price we will pay for CO2 generally varies depending on the amount of CO2 delivered and the price of oil. Once all commitments have commenced, 97 Denbury Resources Inc. Notes to Consolidated Financial Statements our annual commitment under these contracts could range from $41 million to $86 million per year, assuming a $60 per Bbl NYMEX oil price. In the second quarter of 2016, we amended our CO2 offtake agreement with Mississippi Power Company (“MSPC”), which amendment included increasing our offtake percentage from 70% to 100% of CO2 quantities produced and lowering the base price related to the cost of CO2, deliveries of which are currently expected to begin during the first half of 2017. Based on the amended terms in the agreement, we concluded for accounting purposes that the agreement contains an embedded lease related to the pipeline owned by MSPC used to transport CO2 to Denbury. We currently plan to record a capital lease on the balance sheet of approximately $110 million upon lease commencement. We are party to long-term contracts that require us to deliver CO2 to our industrial CO2 customers at various contracted prices, plus we have a CO2 delivery obligation to Genesis related to one CO2 volumetric production payment (“VPP”). Based upon the maximum amounts deliverable as stated in the industrial contracts and the VPP, we estimate that we may be obligated to deliver up to 383 Bcf of CO2 to these customers over the next 12 years. The maximum volume required in any given year is approximately 111 MMcf/d, which we judge to be minor given the size of our Jackson Dome proved CO2 reserves at December 31, 2016, our current production capabilities and our projected levels of CO2 usage for our own tertiary flooding program. Litigation We are involved in various lawsuits, claims and regulatory proceedings incidental to our businesses. While we currently believe that the ultimate outcome of these proceedings, individually and in the aggregate, will not have a material adverse effect on our financial position, results of operations or cash flows, litigation is subject to inherent uncertainties. Although a single or multiple adverse rulings or settlements could possibly have a material adverse effect on our finances, we only accrue for losses from litigation and claims if we determine that a loss is probable and the amount can be reasonably estimated. Riley Ridge Helium Supply Contract Claim As part of our 2010 and 2011 acquisitions of the Riley Ridge Unit and associated gas processing facility that was under construction, we assumed a 20-year helium supply contract under which we agreed to supply to a third-party purchaser the helium separated from the full well stream by operation of the gas processing facility. The helium supply contract provides for the delivery of a minimum contracted quantity of helium, subject to adjustment after startup of the Riley Ridge gas processing facility, with liquidated damages payable if specified quantities of helium are not supplied in accordance with the terms of the contract. The liquidated damages are capped at $8.0 million per contract year and are capped at an aggregate of $46.0 million over the remaining term of the contract. As the gas processing facility has been shut-in since mid-2014, we have not been able to supply helium to the third-party purchaser under the helium supply contract. In a case originally filed in November 2014 by APMTG Helium, LLC, the third-party helium purchaser, after a week of trial on the third-party purchaser’s claim for multiple years of liquidated damages for non-delivery of volumes of helium specified under the helium supply contract, and on our claim that the contractual obligation is excused by virtue of events that fall within the force majeure provisions in the helium supply contract, the trial was stayed in late February 2017 until a later date yet to be determined by the District Court. The Company plans to continue to vigorously defend its position, but we are unable to predict at this time the outcome of this dispute. Settlement of NGS Sub Corp., Evolution, et al v. Denbury Onshore, LLC During the second quarter of 2016, we settled litigation pending since 2013 related to interpretation of the terms of the contracts under which we purchased our interest in the Delhi Field from an affiliate of the entity which continues to own an interest in the field, and claims related to the ongoing financial and operating impact of the June 2013 release of well fluids in that field and our remediation of that release. In the settlement, we paid the co-owner $27.5 million, exchanged various interests in the field, and agreed upon ongoing field operations and related transportation charges. The cash payment was recorded to “Other expenses” in our Consolidated Statements of Operations in the second quarter of 2016. 98 Denbury Resources Inc. Notes to Consolidated Financial Statements Other Contingencies We are subject to audits for various taxes (income, sales and use, and severance) in the various states in which we operate, and from time to time receive assessments for potential taxes that we may owe. In the past, settlement of these matters has not had a material adverse financial impact on us, and currently we have no material assessments for potential taxes. We are subject to various possible contingencies that arise primarily from interpretation of federal and state laws and regulations affecting the oil and natural gas industry. Such contingencies include differing interpretations as to the prices at which oil and natural gas sales may be made, the prices at which royalty owners may be paid for production from their leases, environmental issues and other matters. Although we believe that we have complied with the various laws and regulations, administrative rulings and interpretations thereof, adjustments could be required as new interpretations and regulations are issued. In addition, production rates, marketing and environmental matters are subject to regulation by various federal and state agencies. Note 11.

Unaudited Supplementary Information SUPPLEMENTAL OIL AND NATURAL GAS DISCLOSURES (UNAUDITED) Costs Incurred The following table summarizes costs incurred and capitalized in oil and natural gas property acquisition, exploration and development activities. Property acquisition costs are those costs incurred to purchase, lease or otherwise acquire property, including both undeveloped leasehold and the purchase of reserves in place. Exploration costs include costs of identifying areas that may warrant examination and examining specific areas that are considered to have prospects containing oil and natural gas reserves, including costs of drilling exploratory wells, geological and geophysical costs, and carrying costs on undeveloped properties. Development costs are incurred to obtain access to proved reserves, including the cost of drilling development wells, and to provide facilities for extracting, treating, gathering and storing the oil and natural gas, and the cost of improved recovery systems. We capitalize interest on unevaluated oil and natural gas properties that have ongoing development activities. Included in costs incurred in the table below is capitalized interest of $25.2 million, $28.3 million and $21.8 million during the years ended December 31, 2016, 2015 and 2014, respectively. Costs incurred also include new asset retirement obligations established, as well as changes to asset retirement obligations resulting from revisions in cost estimates or abandonment dates. Asset retirement obligations included in the table below were $3.9 million, $5.5 million and $4.9 million during the years ended December 31, 2016, 2015 and 2014, respectively. See Note 2, Asset Retirement Obligations, for additional information.

Oil and Natural Gas Reserves Net proved oil and natural gas reserve estimates for all years presented were prepared by DeGolyer and MacNaughton, independent petroleum engineers located in Dallas, Texas. These oil and natural gas reserve estimates do not include any value for probable or possible reserves that may exist, nor do they include any value for undeveloped acreage. The reserve estimates represent our net revenue interest in our properties. See Standardized Measure of Discounted Future Net Cash Flows and Changes Therein Relating to Proved Oil and Natural Gas Reserves below for a discussion of the effect of the different prices on reserve quantities and values. Operating costs, production and ad valorem taxes, and future development costs were based on current costs as of December 31, 2016. There are numerous uncertainties inherent in estimating quantities of proved reserves and in projecting the future rates of production and timing of development expenditures. The following reserve data represents estimates only and should not be construed as being exact. Moreover, the present values should not be construed as the current market value of our oil and natural gas reserves or the costs that would be incurred to obtain equivalent reserves. Estimates of reserves as of year-end 2016, 2015 and 2014 were prepared using an average price equal to the unweighted arithmetic average of hydrocarbon prices received on a field-by-field basis on the first day of each month within the applicable fiscal 12-month period. All of our reserves are located in the United States. 102 Denbury Resources Inc.

In order to recognize proved tertiary oil reserves, we must either have an oil production response to CO2 injections or the field must be analogous to an existing tertiary flood. The magnitude of proved reserves that we can book in any given year will depend on our progress with new floods and the timing of the production response. Revision of previous estimates during 2015 reflect the significant decline in commodity prices between December 31, 2014 and 2015, whereby the average first-day-of-the-month NYMEX oil price used in estimating our proved reserves declined from $94.99 per Bbl at December 31, 2014, to $50.28 per Bbl at December 31, 2015, and for natural gas declined from $4.30 per MMBtu at December 31, 2014, to $2.63 per MMBtu at December 31, 2015. These revisions include the elimination of approximately 368 Bcf (61 MMBOE) of proved natural gas reserves at Riley Ridge during 2015, which reserves were reclassified and are no longer considered proved reserves primarily as a result of the decline in average first-day-of-the-month natural gas prices utilized in preparing our December 31, 2015 reserve report. There were no significant additions to our oil and natural gas reserves in 2016, 2015 or 2014, as the magnitude of proved reserves that we can book in any given year depends on our progress with new floods and the timing of the production response, and we initiated no new floods in 2016, 2015 or 2014. Standardized Measure of Discounted Future Net Cash Flows and Changes Therein Relating to Proved Oil and Natural Gas Reserves The Standardized Measure of Discounted Future Net Cash Flows and Changes Therein Relating to Proved Oil and Natural Gas Reserves (“Standardized Measure”) does not purport to present the fair market value of our oil and natural gas properties. An estimate of such value should consider, among other factors, anticipated future prices of oil and natural gas, the probability of recoveries in excess of existing proved reserves, the value of probable reserves and acreage prospects, and perhaps different discount rates. It should be noted that estimates of reserve quantities, especially from new discoveries, are inherently imprecise and subject to substantial revision. 103 Denbury Resources Inc. Unaudited Supplementary Information Under the Standardized Measure, future cash inflows were estimated by applying a first-day-of-the-month 12-month average price to the estimated future production of year-end proved reserves. The product prices used to calculate these reserves have varied widely during the three-year period. These prices have a significant impact on both the quantities and value of the proved reserves, as reductions in oil and natural gas prices can cause wells to reach the end of their economic life much sooner and can make certain proved undeveloped locations uneconomical, both of which reduce the reserves. The following representative oil and natural gas prices were used in the Standardized Measure. These prices were adjusted by field to arrive at the appropriate corporate net price. Oil (NYMEX price per Bbl) Natural Gas (Henry Hub price per MMBtu) December 31, 2016 2015 2014 $ 42.75 $ 50.28 $ 2.55 2.63 94.99 4.30 The decreases in the Standardized Measure of discounted future net cash flows during 2015 and 2016 in the tables that follow were significantly impacted by the decline in first-day-of-the-month average NYMEX oil prices between 2014 and 2016. The weighted-average oil prices we receive relative to NYMEX oil prices (our NYMEX oil price differential) utilized were $3.39 per Bbl below representative NYMEX oil prices as of December 31, 2016, compared to $2.17 per Bbl below representative NYMEX oil prices as of December 31, 2015, and $3.10 per Bbl below representative NYMEX oil prices as of December 31, 2014. Future cash inflows were reduced by estimated future production, development and abandonment costs based on current cost, with no escalation to determine pre-tax cash inflows. Our future net inflows do not include a reduction for cash previously expended on our capitalized CO2 assets that will be consumed in the production of proved tertiary reserves. Future income taxes were computed by applying the statutory tax rate to the excess of net cash inflows over our tax basis in the associated proved oil and natural gas properties. Tax credits and net operating loss carryforwards were also considered in the future income tax calculation. Future net cash inflows after income taxes were discounted using a 10% annual discount rate to arrive at the Standardized Measure.

Changes in and Disagreements with Accountants on Accounting and Financial Disclosure Denbury Resources Inc. None. Item 9A. Controls and Procedures Evaluation of Disclosure Controls and Procedures As of the end of the period covered by this report, an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) was performed under the supervision and with the participation of management, including our Chief Executive Officer and our Chief Financial Officer. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of December 31, 2016, to ensure that information that is required to be disclosed in the reports the Company files and submits under the Securities Exchange Act of 1934 is recorded; that it is processed, summarized and reported within the time periods specified in the SEC’s rules and forms; and that information that is required to be disclosed under the Exchange Act is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. Evaluation of Changes in Internal Control over Financial Reporting Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we have determined that, during the fourth quarter of fiscal 2016, there were no changes in our internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934, as amended. Under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, we assessed the effectiveness of our internal control over financial reporting as of the end of the period covered by this report based on the framework in “Internal Control – Integrated Framework” (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on that assessment, our Chief Executive Officer and our Chief Financial Officer concluded that our internal control over financial reporting was effective to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of our financial statements for external purposes in accordance with U.S. generally accepted accounting principles. The effectiveness of our internal control over financial reporting as of December 31, 2016, has been audited by PricewaterhouseCoopers LLP, an independent registered public accounting firm, as stated in the report that appears herein. Important Considerations The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, there can be no assurance that any system of disclosure controls and procedures or internal control over financial reporting will be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.
