Vanguard Natural Resources, LLC and Subsidiaries
Unaudited Pro Forma Combined Financial Information

On December 31, 2010, Vanguard completed an acquisition pursuant to a purchase agreement with Denbury Resources Inc. ("Denbury"), Encore Partners GP Holdings LLC, Encore Partners LP Holdings LLC and Encore Operating, L.P. (collectively, the "Selling Parties" and, together with Denbury, the "Selling Parties") to acquire all of the member interests in Encore GP and 20,924,055 common units representing limited partner interests in Encore, representing, with the general partner interest owned by Encore GP consisting of 504,851 general partner units, a 46.7% aggregate equity interest in Encore (the "Encore Sponsor Interest Acquisition"). As consideration for the purchase, Vanguard paid $300.0 million in cash and issued 3,137,255 Vanguard common units, valued at approximately $93 million.

On July 11, 2011, Vanguard and Encore announced the execution of a definitive agreement that would result in a merger whereby Encore would become a wholly-owned subsidiary of VNG, through a unit-for-unit exchange (the "Merger"). Under the terms of the definitive merger agreement, Encore's public unitholders received 0.75 Vanguard common units in exchange for each Encore common unit they owned at closing. The transaction resulted in 18,420,606 additional common units being issued by Vanguard. The terms of the definitive merger agreement were unanimously approved by the members of the Encore Conflicts Committee, who negotiated the terms on behalf of Encore and was comprised solely of independent directors. The members of the Vanguard Conflicts Committee, which is also comprised solely of independent directors, negotiated the terms on behalf of Vanguard and also voted unanimously in favor of the Merger. The completion of the Merger was subject to approval by a majority of the outstanding Encore common units. As of July 11, 2011,Vanguard's operating company, VNG, owned Encore's general partner and approximately 46.0% of the Encore outstanding common units and executed the definitive merger agreement between Vanguard and Encore. The completion of the Merger was also subject to the approval of the issuance of additional Vanguard common units in connection with the Merger by the affirmative vote of a majority of the votes cast by Vanguard unitholders. On October 31, 2011, Vanguard and ENP submitted the definitive proxy statement to their respective unitholders.  The special meeting of unitholders for each of Vanguard and ENP took place on November 30, 2011 and the unitholders of each of Vanguard and ENP approved the Merger.  Based on 24,560,808 ENP common units outstanding on November 30, 2011, Vanguard issued 18,420,606 common units to ENP common unitholders at the closing of the merger, December 1, 2011.
 
On June 22, 2011, Vanguard and Encore entered into two Purchase and Sale Agreements to acquire producing oil and natural gas assets in the Permian Basin in West Texas (the "Purchased Assets") from a private seller. Vanguard and Encore agreed to purchase 50% of the Purchased Assets for an aggregate of $85.0 million and each paid the seller a non-refundable deposit of $4.25 million. We refer to this acquisition as the “Permian Basin Acquisition I.” This acquisition was completed on July 29, 2011 for an aggregate adjusted purchase price of $81.4 million, subject to customary post-closing adjustments to be determined. The effective date of this acquisition was May 1, 2011. The purchase price was funded with borrowings under Vanguard's reserve-based credit facility and ENP's credit facility.

The following unaudited pro forma combined financial information is based on the historical consolidated financial statements of Vanguard and Encore, adjusted to reflect the Merger of Vanguard and Encore and the Encore Sponsor Interest Acquisition, which includes the Vanguard common unit offering completed in October 2010, the issuance of Vanguard's common units to Denbury, and other financing transactions. Vanguard's historical consolidated statement of operations for the year ended December 31, 2010 and the nine months ended September 30, 2011 have also been adjusted to give pro forma effect to the Parker Creek Acquisition completed during May 2010 and the Permian Basin Acquisition I completed during July 2011 as presented in Notes 3 and 5 to the unaudited pro forma combined financial information.

 
 
 
The unaudited pro forma combined financial statements give effect to the events set forth below:

 
•
The December 2010 Encore Sponsor Interest Acquisition.
 
•
The issuance of 18,420,606 Vanguard common units to Encore's public unitholders in exchange for each Encore common unit they owned at the closing of the Merger.
 
•
The elimination of transaction costs incurred in the Encore Sponsor Interest Acquisition.
 
•
The elimination of certain general and administrative expenses resulting from Encore not being a separate public company after the completion of the Merger.
 
•
Adjustments to conform the classification of revenues and expenses in Encore's historical statements of operations to Vanguard's classification of similar revenues and expenses.
 
•
Adjustments to conform Encore's historical accounting policies related to oil and natural gas properties from successful efforts to full cost accounting.
 
•
Adjustments to interest expense related to borrowings under Vanguard's term loan and reserve-based credit facility to fund the Encore Sponsor Interest Acquisition.
 
•
Adjustments for the Vanguard common units issued in the October 2010 equity offering and issued to Denbury in connection with the Encore Sponsor Interest Acquisition.
 
•
Vanguard's Parker Creek Acquisition completed during May 2010 and the effect of the related equity offering.
 
•
Vanguard's and Encore’s Permian Basin Acquisition I completed during July 2011 and the increase in interest expense related to borrowings under Vanguard's reserve-based credit facility and Encore’s credit agreement to fund the acquisition.
 
•
The elimination of nonrecurring losses related to the Parker Creek Acquisition completed by Vanguard during May 2010 and the Permian Basin Acquisition I completed during July 2011.

The unaudited pro forma combined balance sheet gives effect to the Merger as if it had occurred on September 30, 2011. The unaudited pro forma combined statements of operations combine the results of operations of Vanguard and Encore for the year ended December 31, 2010 and the nine months ended September 30, 2011, as if the Merger, the Encore Sponsor Interest Acquisition, the Permian Basin Acquisition I completed during July 2011 and the Parker Creek Acquisition completed during May 2010 (see Note 5) had occurred on January 1, 2010.

The unaudited pro forma combined financial information should be read in conjunction with Encore's and Vanguard's Forms 10-K for the year ended December 31, 2010 and Encore's and Vanguard's Forms 10-Q for the quarter ended September 30, 2011.

The unaudited pro forma combined financial information is for informational purposes only and is not intended to represent or to be indicative of the combined results of operations or financial position that Vanguard would have reported had the Merger, the Encore Sponsor Interest Acquisition, Permian Basin Acquisition I and the Parker Creek Acquisition been completed as of the dates set forth in this unaudited pro forma combined financial information and should not be taken as indicative of Vanguard's future combined results of operations or financial position. The actual results may differ significantly from that reflected in the unaudited pro forma combined financial information for a number of reasons, including, but not limited to, differences between the assumptions used to prepare the unaudited pro forma combined financial information and actual results.

NOTES TO UNAUDITED PRO FORMA
COMBINED FINANCIAL INFORMATION

Note 1 Basis of Presentation

On December 31, 2010, Vanguard completed the Encore Sponsor Interest Acquisition, whereby Vanguard acquired all of the member interest in Encore GP (which owns 504,851 general partner units in Encore) and 20,924,055 common units representing limited partner interests in Encore, representing, together with the general partner units, a 46.7% aggregate equity interest in Encore. As consideration for the purchase, Vanguard paid $300.0 million in cash and issued 3,137,255 Vanguard common units, valued at approximately $93 million.

On July 11, 2011, Vanguard and Encore announced the execution of a definitive merger agreement that would result in a merger whereby Encore would become a wholly-owned subsidiary of VNG, through a unit-for-unit exchange (the “Merger”). Under the terms of the definitive merger agreement, Encore's public unitholders received 0.75 Vanguard common units in exchange for each Encore common unit they owned at closing. The transaction resulted in 18,420,606 additional common units being issued by Vanguard. The terms of the definitive merger agreement were unanimously approved by the members of the Encore Conflicts Committee, who negotiated the terms on behalf of Encore and was comprised solely of independent directors. The members of the Vanguard Conflicts Committee, which is also comprised solely of independent directors, negotiated the terms on behalf of Vanguard and also voted unanimously in favor of the Merger. The completion of the Merger was subject to approval by a majority of the outstanding Encore common units. As of July 11, 2011, Vanguard's operating company, Vanguard Natural Gas, LLC, owned Encore's general partner and approximately 46% of the Encore outstanding common units and executed the definitive merger agreement between Vanguard and Encore. The completion of the Merger was also subject to the approval of the issuance of additional Vanguard common units in connection with the Merger by the affirmative vote of a majority of the votes cast by Vanguard unitholders. On October 31, 2011, Vanguard and ENP submitted the definitive proxy statement to their respective unitholders. The special meeting of unitholders for each of Vanguard and ENP took place on November 30, 2011 and the unitholders of each of Vanguard and ENP approved the Merger. Based on 24,560,808 ENP common units outstanding on November 30, 2011, Vanguard issued 18,420,606 common units to ENP common unitholders at the closing of the merger, December 1, 2011.
 
The Merger will be accounted for in accordance with Financial Accounting Standards Board Accounting Standards Codification 810, Consolidations — Overall — Changes in Parent's Ownership Interest in a Subsidiary, which is referred to as FASB ASC 810. Since Encore is a consolidated subsidiary of Vanguard, the changes in Vanguard's ownership interest in Encore will be accounted for as an equity transaction and no gain or loss will be recognized as a result of the Merger.

The accompanying unaudited pro forma combined balance sheet at September 30, 2011 has been prepared to give effect to the Merger as if it had occurred on September 30, 2011 and the unaudited pro forma combined statements of operations have been prepared to give effect to the Merger and the Encore Sponsor Interest Acquisition, including the Vanguard common unit offering completed in October 2010, the issuance of Vanguard's common units to Denbury, and other financing transactions, as if they had occurred on January 1, 2010. Vanguard's unaudited pro forma statements of operations, which are included in the unaudited pro forma combined statements of operations, also include the pro forma effects of the Permian Basin Acquisition I completed during July 2011 and the Parker Creek Acquisition completed during May 2010 and the and the related equity financings as if they had occurred on January 1, 2010. The Permian Basin Acquisition I and the Parker Creek Acquisition are unrelated to the Merger.
 
 
 
 
The pro forma effects of the Permian Basin Acquisition I and the Parker Creek Acquisition are presented in Notes 3 and 5 to the unaudited pro forma combined financial information.

The unaudited pro forma combined financial information includes adjustments to conform Encore's accounting for oil and natural gas properties to the full cost method. Vanguard follows the full cost method of accounting for oil and natural gas properties while Encore follows the successful efforts method of accounting for oil and natural gas properties. Certain costs that are capitalized under the full cost method are expensed under the successful efforts method. These costs consist primarily of unsuccessful exploration drilling costs, geological and geophysical costs, delay rental on leases, abandonment costs and general and administrative expenses directly related to exploration and development activities. Under the successful efforts method of accounting, proved property acquisition costs are amortized on a unit-of-production basis over total proved reserves and costs of wells, related equipment and facilities are depreciated over the life of the proved developed reserves that will utilize those capitalized assets on a field-by-field basis. Under the full cost method of accounting, property acquisition costs, costs of wells, related equipment and facilities and future development costs are included in a single full cost pool, which is amortized on a unit-of-production basis over total proved reserves.

The unaudited pro forma combined financial statements and underlying pro forma adjustments are based upon currently available information and certain estimates and assumptions made by the management of Vanguard and Encore; therefore, actual results could differ materially from the pro forma information. However, management believes the assumptions provide a reasonable basis for presenting the significant effects of the Merger. Vanguard and Encore believe the pro forma adjustments give appropriate effect to those assumptions and are properly applied in the pro forma information.
 
Note 2 Unaudited Pro forma Combined Balance Sheet

Pro Forma Adjustment to the Unaudited Pro Forma Combined Balance Sheet

Adjustment (a) eliminates the non-controlling interests in Encore. As provided for in FASB ASC 810, the Merger is treated as an equity transaction, with no resulting gain or loss. Each Encore public unitholder was issued 0.75 Vanguard common units for each Encore common unit held at closing. The number of Vanguard common units issued to effect the Merger is calculated as follows:

Note 5 Vanguard's Unaudited Pro Forma Consolidated Statement of Operations

On April 30, 2010, Vanguard entered into a definitive agreement with a private seller for the acquisition of certain oil and natural gas properties located in Mississippi, Texas and New Mexico. We refer to this acquisition as the "Parker Creek Acquisition." The purchase price for said assets was $113.1 million with an effective date of May 1, 2010. We completed this acquisition on May 20, 2010. The adjusted purchase price of $114.3 million considered final purchase price adjustments of approximately $1.2 million. The purchase price was funded from the approximate $71.5 million in net proceeds from Vanguard's May 2010 equity offering and with borrowings under Vanguard's existing reserve-based credit facility.

On June 22, 2011, Vanguard and Encore entered into two Purchase and Sale Agreements to acquire producing oil and natural gas assets in the Permian Basin in West Texas (the "Purchased Assets") from a private seller. Vanguard and Encore agreed to purchase 50% of the Purchased Assets for an aggregate of $85.0 million and each paid the seller a non-refundable deposit of $4.25 million. We refer to this acquisition as the “Permian Basin Acquisition I.” This acquisition was completed on July 29, 2011 for an aggregate adjusted purchase price of $81.4 million, subject to customary post-closing adjustments to be determined. The effective date of this acquisition was May 1, 2011. The purchase price was funded with borrowings under Vanguard's reserve-based credit facility and ENP's credit facility.

Vanguard's unaudited pro forma consolidated statement of operations included in the unaudited pro forma combined statement of operations give effect to the Parker Creek Acquisition completed during May 2010 and the Permian Basin Acquisition I completed during July 2011 as if they had occurred on January 1, 2010.
