Denbury to Acquire Encore in a $4.5 Billion Transaction

News Release
Released at 3:00 p.m. CST

     DALLAS – November 1, 2009 – Denbury Resources Inc. (NYSE: DNR) (“Denbury”) and Encore Acquisition Company (NYSE: EAC) (“Encore”) today jointly announced that they have entered into a definitive merger agreement pursuant to which Denbury will acquire Encore in a transaction valued at approximately $4.5 billion, including the assumption of debt and the value of the minority interest in Encore Energy Partners LP (NYSE:ENP). The combined company will continue to be known as Denbury Resources Inc. (the “Company”) and will be headquartered in Plano, Texas.

     Under the definitive agreement, Encore stockholders will receive $50.00 per share for each share of Encore common stock, comprised of $15.00 in cash and $35.00 in Denbury common stock subject to both an election feature and a collar mechanism on the stock portion of the consideration.

     The transaction positions the Company as one of the largest crude oil-focused, independent North American exploration and production companies. The acquisition will also create one of the largest CO₂ enhanced oil recovery (“EOR”) platforms diversified across the Gulf Coast and Rocky Mountain regions, complemented by ownership and control of the Jackson Dome CO₂ source in Mississippi and CO₂ sequestration contracts secured with anthropogenic sources in the Gulf Coast, Midwest and Rockies. The combined companies will have over 500 MMBOE of additional potential barrels recoverable with CO₂ tertiary operations. The longer lead-time of CO₂ project development in the Rockies is ideally matched with a strong growth profile from low-risk development of unconventional resource plays in the Bakken oil shale in North Dakota and the Haynesville shale in North Louisiana. Encore has one of the larger acreage positions in the prolific Bakken oil shale with over 300,000 net acres.

     “Encore is an excellent fit with Denbury’s CO₂ EOR program,” said Phil Rykhoek, Chief Executive Officer of Denbury. “Encore has built an enviable asset portfolio in the Rockies, anchored by mature legacy crude oil assets, and our combined size and scale of operations will allow us to undertake significantly larger CO₂ projects in the Gulf Coast and the Rockies. This combination will also further enhance Denbury’s position as the natural buyer and owner of mature oil properties in our core regions and the partner of choice for CO₂ emitters looking to reduce their carbon footprint. With the addition of the Encore properties, we more than double our current inventory of oil reserves recoverable with CO₂, and greatly expand our future growth potential with a second new core EOR area in the Rockies that has significant future expansion opportunities. The anticipated EOR production from the Encore properties will fit nicely into our overall EOR program, providing production growth in 2015 and beyond, about the time when we anticipate nearing the production peak of our existing EOR field inventory. In addition, the growth potential from Encore’s Bakken shale oil play further enhances its value and provides short-term production growth and cash flow as we develop the longer term EOR program. The transaction is expected to be meaningfully accretive to Denbury on a cash flow basis, between 8% and 18% depending on the ultimate number of Denbury shares issued, and the combined size, scale and access to capital will benefit both groups of stockholders.”

     Jonny Brumley, Chief Executive Officer of Encore, stated, “The combined companies have a unique blend of large oil fields with huge upside potential. The large reserve and production base will increase the operational and financial flexibility allowing for more efficient development of the assets of both of our companies. We have been impressed by the amount of progress Denbury has made in building a world-class enhanced oil recovery business. Denbury has the experience and expertise to effectively capture the full value of Encore’s EOR inventory and the combined entities will provide the necessary size and scale to develop and fully recognize that potential. The transaction recognizes the value Encore has created for its stockholders and positions the combined company to deliver above average value creation for both sets of stockholders going forward. Encore has a dedicated group of employees that have worked hard and built a company to be proud of.”

     Denbury is currently in the process of setting its 2010 capital budget. The budget will be focused on high-grading the combined company’s best projects, while at the same time maintaining the Company’s strong financial and liquidity positions. Denbury anticipates announcing the combined 2010 capital budget at its upcoming analyst meeting on November 12^th and November 13^th.

Terms of the Transaction

     In calculating the exchange ratio range for the collar mechanism, the Denbury common stock was initially valued at $15.10 per share. The collar mechanism is limited to a 12% upward or downward movement in the Denbury share price. The final number of Denbury shares to be issued will be adjusted based on the volume weighted average price of Denbury common stock for a 20 day trading period ending on the second day prior to closing. Based on this mechanism, if Denbury stock trades between $13.29 and $16.91, the Encore stockholders will receive between 2.0698 and 2.6336 shares of Denbury common stock for each of their shares of Encore common

stock, but not higher or lower than these share amounts if Denbury common stock trades outside this range. Encore stockholders will also have an option to receive all stock or all cash, subject to a proration feature such that the overall mix of consideration is 70% Denbury common stock and 30% cash.

     Denbury intends to finance this transaction with a combination of equity and debt. In connection with the transaction, Denbury has received a commitment letter for an underwritten financing from J.P. Morgan for a new $1.6 billion bank revolving credit facility and a $1.25 billion bridge financing to subordinated debt facility. The new debt financing will be used to fund the cash portion of the consideration, potentially retire and replace $825 million of Encore’s outstanding subordinated notes, all of which have a change of control put option at 101%, replace Encore’s existing bank facility which has approximately $180 million currently drawn and outstanding, and to pay other fees and expenses. Denbury expects to issue between 115 million and 146 million shares of common stock to fund the equity portion of the merger consideration. During 2010, Denbury intends to sell non-core oil and gas properties of the combined companies in order to reduce its overall debt levels incurred as part of the acquisition, with targeted sales proceeds of at least $500 million. Denbury will own the general partner interest of Encore Energy Partners and approximately 21 million limited partner units. The Company may decide to sell certain properties to Encore Energy Partners as a means to reduce the Company’s debt. The new combined company will have a vast inventory of long-life oil fields that could be excellent candidates for asset drop-downs.

     The Boards of Directors of both companies have unanimously approved the merger agreement, and each will recommend approval of the transaction to its respective stockholders. Completion of the transaction is subject to the approval of both Denbury and Encore stockholders, regulatory approvals and other customary conditions. Post closing, it is anticipated that Denbury stockholders will own between 63% and 68% of the combined company and the Encore stockholders will own between 32% and 37% of the combined company. The transaction is expected to close in the first quarter of 2010 and Denbury’s board and senior management will remain unchanged.

     J.P. Morgan Securities Inc. acted as exclusive financial advisor to Denbury and Barclay’s Capital Inc. acted as exclusive financial advisor to Encore. Baker & Hostetler LLP acted as legal counsel to Denbury and Baker Botts L.L.P. as legal counsel to Encore.
