Forward-looking statements use forward-looking terms such as “believe,” “expect,” “may,” “intend,” “will,” “project,” “budget,” “should” or “anticipate” or other similar words. These statements discuss “forward-looking” information such as:
CO2 availability, deliverability and tertiary production targets;
 
other anticipated capital expenditures and budgets;
 
future cash flows and borrowings;
 
pursuit of potential future acquisition or drilling opportunities; and

Summary
In this prospectus, when we use the terms “Denbury,” the “Company,” “we” or “our,” we mean Denbury Resources Inc. and its subsidiaries on a consolidated basis, unless otherwise indicated or the context requires otherwise. Reference oil and natural gas prices used in this prospectus, mean the NYMEX WTI oil price and the Henry Hub natural gas cash price per MMbtu, unless otherwise indicated. Oil and natural gas terms used in this prospectus are defined in the “Glossary” section. Principal executive offices of the Company are located at 5100 Tennyson Pkwy., Suite 1200, Plano, Texas 75024. The phone number is (972) 673-2000.
The company
We are an independent oil and gas company engaged in acquisition, development and exploration activities in the U.S. Gulf Coast region. We are the largest oil and natural gas producer in Mississippi, own the largest reserves of carbon dioxide (“CO2”) used for tertiary oil recovery east of the Mississippi River, and hold significant operating acreage onshore Louisiana and in the Barnett Shale play near Forth Worth, Texas. Our goal is to increase the value of acquired properties through a combination of exploitation, drilling and proven engineering extraction processes, including secondary (waterflood) and tertiary recovery operations.
Since we acquired our first carbon dioxide tertiary flood in Mississippi over six years ago, we have gradually increased our emphasis on these types of operations. We particularly like this play because of its risk profile, rate of return and lack of competition in our operating area. Generally, from East Texas to Florida, there are no known significant natural sources of carbon dioxide except our own, and these large volumes of CO2 that we own drive the play. Please refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and the section entitled “Oil and Gas Operations—Our CO2 Assets” contained in our Form 10-K for the year ended December 31, 2005 for further information regarding these operations, their potential, and the ramifications of this focus.
Recent acquisition
On January 31, 2006, we completed an acquisition of three producing oil properties that are future potential CO2 tertiary oil flood candidates: Tinsley Field approximately 40 miles northwest of Jackson, Mississippi, Citronelle Field in Southwest Alabama, and the smaller South Cypress Creek Field near the Company’s Eucutta Field in Eastern Mississippi. We expect to begin our initial tertiary development work at Tinsley Field during 2006, with more extensive development planned for 2007. The timing of tertiary development at Citronelle Field is uncertain as we will need to build a 60 to 70 mile pipeline extension of our CO2 line to East Mississippi before flooding can commence, and South Cypress Creek will probably be flooded following our initial development of our other East Mississippi properties.
The preliminary adjusted purchase price for these three properties was approximately $248 million, after adjusting for interim net cash flow and minor purchase price adjustments. The acquisition was funded with proceeds of the $150 million of senior subordinated notes issued in December 2005 and bank financing under the Company’s existing credit facility, bringing the outstanding balance of the Company’s bank debt as of January 31, 2006 to approximately $100 million ($120 million as of April 14, 2006).

Table of Contents

These three fields are currently producing approximately 2,200 BOE/d net to the acquired interests, and have proved reserves of approximately 14.4 million BOEs. We operate all three fields and own the majority of the working interests.
First quarter 2006 production estimate
Based on preliminary estimates, the Company’s production for the first quarter of 2006 is expected to be between 35,000 to 36,000 BOE/d. Production by area is expected to be approximately 12,400 BOE/d from the non-CO2 floods in Mississippi, 9,750 BOE/d from CO2 floods, 8,350 BOE/d from Louisiana, 4,000 BOE/d from the Barnett Shale, and approximately 1,000 BOE/d from Alabama, in each case plus or minus up to 250 BOE/d. First quarter preliminary estimates include two months of production from the three properties acquired in late January 2006, production from which is estimated to contribute approximately 1,400 BOE/d to estimated total first quarter production.
First quarter 2006 estimated preliminary financial data
Each fiscal quarter we charge to earnings any changes in the fair value of our derivative contracts. We preliminarily estimate that this non-cash charge for the first quarter of 2006 will be approximately $10.9 million; for the quarter we also will record for the first time a non-cash charge to earnings estimated to be up to $3.0 million to reflect the adoption on January 1, 2006 of SFAS No. 123(R) related to compensation expense for share-based compensation.

Description of capital stock
General
As of April 14, 2006, we are authorized to issue up to 275,000,000 shares of stock, including up to 250,000,000 shares of common stock, par value $.001 per share, and up to 25,000,000 shares of preferred stock, par value $.001 per share. As of April 14, 2006, we had 115,534,755 shares of common stock and no shares of preferred stock outstanding. This excludes 8,495,741 shares of common stock subject to options under our option plans, and 360,231 shares of common stock subject to stock appreciation rights outstanding as of April 14, 2006 at a weighted average option price of $8.36 per share and a weighted average stock appreciation right base price of $25.23.
Common stock
The following is a summary of the key terms and provisions of our common stock. You should refer to the applicable provisions of our Restated Certificate of Incorporation, as amended, bylaws and the Delaware General Corporation Law for a complete statement of the terms and rights of our capital stock.
Voting rights. Each holder of common stock is entitled to one vote per share. Subject to the rights, if any, of the holders of any series of preferred stock pursuant to applicable law or the provision of the certificate of designation creating that series, all voting rights are vested in the holders of shares of common stock. Holders of shares of common stock have non-cumulative voting rights, which means that the holders of more than 50% of the shares voting for the election of directors can elect 100% of the directors, and the holders of the remaining shares voting for the election of directors will not be able to elect any directors.
Dividends. Dividends may be paid to the holders of common stock when, as and if declared by the board of directors out of funds legally available for their payment, subject to the rights of holders of any preferred stock. We have never declared a cash dividend and intend to continue our policy of using retained earnings for expansion of our business.
Rights upon liquidation. In the event of our voluntary or involuntary liquidation, dissolution or winding up, the holders of our common stock will be entitled to share equally, in proportion to the number of shares of common stock held by them, in any of our assets available for distribution after the payment in full of all debts and distributions and after the holders of all series of outstanding preferred stock, if any, have received their liquidation preferences in full.
Non-assessable. All outstanding shares of common stock are fully paid and non-assessable. Any additional common stock we offer and issue under this Prospectus will be fully paid and non-assessable when distributed.
Anti-takeover measures. Our Restated Certificate of Incorporation, as amended, requires a two-thirds majority vote by the Board on many significant transactions, including amending our charter or bylaws, issuing equity securities, creating any series of preferred stock, issuing debt in excess of 10% of our assets, making acquisitions or dispositions with a purchase price in excess of 20% of our assets, or increasing or decreasing the size of our Board. Because a smaller number of directors than a majority can join together to block future transactions, issuances of securities or changes in our organizational documents, there is an increased possibility that these transactions will not be accomplished.

No preemptive rights. Holders of common stock are not entitled to preemptive purchase rights in future offerings of our common stock.
Listing. Our outstanding shares of common stock are listed on the New York Stock Exchange under the symbol “DNR.” Any additional common stock we offer and issue under this Prospectus will also be listed on the New York Stock Exchange or any other exchange on which our common stock is then traded.
Underwriting
We are offering the shares of common stock described in this prospectus through J.P. Morgan Securities Inc., the underwriter. We have entered into an underwriting agreement with the underwriter. Subject to the terms and conditions of the underwriting agreement, we have agreed to sell to the underwriter, and the underwriter has agreed to purchase, at the purchase price set forth on the cover page of this prospectus, 3,492,595 shares of common stock.
The underwriter is committed to purchase all the common shares offered by us if it purchases any shares.
The underwriter proposes to offer the shares of common stock from time to time for sale in one or more transactions in the over-the-counter market, through negotiated transactions or otherwise at market prices prevailing at the time of the sale, at prices related to prevailing market prices or at negotiated prices, subject to receipt and acceptance by it and subject to its right to reject any order in whole or in part. In connection with the sale of the shares of common stock offered hereby, the underwriter may be deemed to have received compensation in the form of underwriting discounts. The underwriter may effect such transactions by selling shares of the common stock offered hereby to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions from the underwriter and/or purchasers of shares of common stock for whom they may act as agents or to whom they may sell as principal.
The underwriter has an option to buy up to 523,889 additional shares of common stock from us to cover sales of shares by the underwriter which exceed the number of shares specified above. The underwriter has 30 days from the date of this prospectus to exercise this over-allotment option. If any additional shares of common stock are purchased, the underwriter will offer the additional shares in the same manner as those on which the shares are being offered.
We estimate that the total expenses of this offering, including registration, filing and listing fees, printing fees and legal and accounting expenses, will be approximately $300,000.
We, our directors and executive officers have entered or will enter into lock-up agreements with the underwriter pursuant to which we and each of these persons, with limited exceptions, for a period of 75 days after the date of this prospectus, may not, without the prior written consent of the underwriter, (1) offer, pledge, announce the intention to sell, sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly, any shares of our common stock (including, without limitation, common stock which may be deemed to be beneficially owned by such directors and executive officers in accordance with the rules and regulations of the SEC and securities which may be issued upon exercise of a stock option or warrant) or (2) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the common stock, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of common

stock or such other securities, in cash or otherwise. The lock-up agreement described above will not apply to sales or transfers of common stock by our directors and executive officers, so long as the aggregate number of shares of common stock sold or transferred by them during the 75 days after the date of this prospectus does not exceed 200,000 shares.
We have agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1933.
Our common stock is listed on the New York Stock Exchange under the symbol “DNR”.
In connection with this offering, the underwriter may engage in stabilizing transactions, which involves making bids for, purchasing and selling shares of common stock in the open market for the purpose of preventing or retarding a decline in the market price of the common stock while this offering is in progress. These stabilizing transactions may include making short sales of the common stock, which involves the sale by the underwriter of a greater number of shares of common stock than it is required to purchase in this offering, and purchasing shares of common stock on the open market to cover positions created by short sales. Short sales may be “covered” shorts, which are short positions in an amount not greater than the underwriter’s over-allotment option referred to above, or may be “naked” shorts, which are short positions in excess of that amount. The underwriter may close out any covered short position either by exercising its over-allotment option, in whole or in part, or by purchasing shares in the open market. In making this determination, the underwriter will consider, among other things, the price of shares available for purchase in the open market compared to the price at which the underwriter may purchase shares through the over-allotment option. A naked short position is more likely to be created if the underwriter is concerned that there may be downward pressure on the price of the common stock in the open market that could adversely affect investors who purchase in this offering. To the extent that the underwriter creates a naked short position, it will purchase shares in the open market to cover the position.
The underwriter has advised us that, pursuant to Regulation M of the Securities Act of 1933, it may also engage in other activities that stabilize, maintain or otherwise affect the price of the common stock.
These activities may have the effect of raising or maintaining the market price of the common stock or preventing or retarding a decline in the market price of the common stock, and, as a result, the price of the common stock may be higher than the price that otherwise might exist in the open market. If the underwriter commences these activities, it may discontinue them at any time. The underwriter may carry out these transactions on the New York Stock Exchange, in the over-the-counter market or otherwise.
The underwriter and its affiliates have provided in the past to us and our affiliates and may provide from time to time in the future certain commercial banking, financial advisory, investment banking and other services for us and such affiliates in the ordinary course of their business, for which they have received and may continue to receive customary fees and commissions. In addition, from time to time, the underwriter and its affiliates may effect transactions for their own account or the account of customers, and hold on behalf of themselves or their customers, long or short positions in our debt or equity securities or loans, and may do so in the future. As an affiliate of the underwriter is expected to receive a portion of the net proceeds from this offering, this offering is being conducted pursuant to NASD Conduct Rule 2710(h).

Commission position on indemnification for
Securities Act liabilities
Section 145 of the Delaware General Corporation Law (the “DGCL”), empowers us under specified circumstances, to indemnify our directors, officers, employees and agents in connection with actions, suits or proceedings brought against them or threatened by reason of the fact that they were our directors, officers, employees or agents, so long as they acted in good faith and in a manner that they reasonably believed to be in, or not opposed to, the best interests of our Company, and with respect to any criminal action, that they had no reasonable cause to believe their conduct was unlawful. With respect to suits by or in the right of our Company, however, indemnification is generally limited to attorneys’ fees and other expenses and is not available if such person is adjudged to be liable to us, unless a court determines that indemnification is appropriate.
Article IX of our Restated Certificate of Incorporation, as amended requires indemnification of directors, officers and other employees to the fullest extent permitted by Section 145 of the DGCL. Furthermore, Article IX explicitly provides that:
we may advance expenses, including reasonable attorneys’ fees, to individuals entitled to indemnification;

13


Table of Contents

we may not take any action to diminish or reduce the rights of individuals entitled to indemnification after the occurrence of the events to which the indemnification relates; and
 
any person entitled to indemnification by us may bring suit against us if we do not pay them within 30 days after receiving a written demand for indemnification and, if successful, such person may recover their expenses for such suit, including attorneys’ fees, from us. In the suit, we will have the burden of proving any defense that the person is not eligible for indemnification under the DGCL.
Additionally, we maintain directors and officers insurance which includes coverage for liability under the federal securities laws.
Article X of our Restated Certificate of Incorporation, as amended limits the personal liability of a director to us or our stockholders for monetary damages for breach of fiduciary duty as a director provided that a director’s liability may not be limited (i) for any breach of the director’s duty of loyalty to us or our stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 (relating to liability for unauthorized acquisitions or redemptions of, or dividends on, capital stock) of the DGCL or (iv) for any transaction from which the director derived an improper personal benefit.
Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise, we have been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable.
