The Merger Agreement contains customary representation, warranties and covenants by each of the parties. Completion of the Merger is conditioned upon, among other things: (1) approval of the Merger Agreement and the Merger by the affirmative vote or consent of holders of a majority of the outstanding ENP Common Units, (2) approval of the issuance of new VNR Common Units in connection with the Merger (the “New Common Unit Issuance”) by the affirmative vote or consent of holders of a majority of the VNR Common Units voting thereon, (3) applicable regulatory approvals, (4) the absence of certain legal injunctions or impediments prohibiting the Merger and the other transactions contemplated by the Merger Agreement, (5) the effectiveness of a registration statement on Form S-4 with respect to the New Common Unit Issuance, (6) approval for the listing on the New York Stock Exchange of the VNR Common Units issued pursuant to the New Common Unit Issuance, and (7) the receipt of certain tax opinions.

The Merger Agreement contains provisions granting both ENP and VNR the right to terminate the Merger Agreement for certain reasons, including, among others, if (1) the Merger does not occur on or before December 31, 2011, (2) ENP fails to obtain the requisite unitholder approval of the Merger Agreement and the Merger, (3) VNR fails to obtain the requisite unitholder approval of the New Common Unit Issuance, or (4) either the ENP GP board of directors or the conflicts committee thereof (the “ENP Conflicts Committee”), in accordance with the Merger Agreement, changes its recommendation to the ENP unitholders with respect to the vote to approve the Merger Agreement and the Merger. ENP will pay VNR a $20.0 million termination fee if either party terminates the Merger Agreement because the ENP GP board of directors or the ENP Conflicts Committee changed its recommendation.

The limited liability company agreement of ENP GP will be amended and restated in substantially the form attached as Annex A to the Merger Agreement, effective upon the consummation of the Merger. In addition, the limited partnership agreement of ENP will be amended and restated in substantially the form attached as Annex B to the Merger Agreement effective upon the consummation of the Merger.

VNG, a wholly-owned subsidiary of VNR, already owns the general partner of ENP and approximately 45.6% of the outstanding ENP Common Units. For additional information about the business and contractual relationships between VNR and ENP, please read ENP’s Quarterly Report on Form 10-Q for the three months ended March 31, 2011.

The ENP Conflicts Committee unanimously determined that the Merger, the Merger Agreement, and the transactions contemplated thereby are fair and reasonable to, and in the best interests of, ENP and the holders of ENP Common Units unaffiliated with VNR. The actions taken by the ENP Conflicts Committee constitute “Special Approval” under ENP’s partnership agreement. The ENP Conflicts Committee also recommended that the Merger, the Merger Agreement and the transactions contemplated thereby be approved by the ENP GP board of directors and the holders of ENP Common Units. Based in part on such determination, Special Approval and recommendation, the ENP GP board of directors approved the Merger, the Merger Agreement and the transactions contemplated thereby, and recommended that the holders of ENP Common Units vote in favor of thereof.

In addition, the conflicts committee of the VNR board of directors (the “VNR Conflicts Committee”) unanimously determined that the Merger, the Merger Agreement, and the transactions contemplated thereby, including the New Common Unit Issuance, are fair and reasonable to, and in the best interests of, VNR and the holders of VNR Common Units unaffiliated with VNR. The actions taken by the VNR Conflicts Committee constitute “Special Approval” under VNR’s limited liability company agreement. The VNR Conflicts Committee also recommended that the Merger, the Merger Agreement and the transactions contemplated thereby, including the New Common Unit Issuance, be approved by the VNR board of directors, and the New Common Unit Issuance be approved by the holders of VNR Common Units. Based in part on such determination, Special Approval and recommendation, the VNR board of directors approved the Merger, the Merger Agreement and the transactions contemplated thereby, including the New Common Unit Issuance, and recommended that the holders of VNR Common Units vote in favor of the New Common Unit Issuance.

Voting Agreement

In connection with the Merger Agreement, VNR, VNG, MergerCo, ENP and ENP GP entered into a Voting Agreement dated as of July 10, 2011 (the “Voting Agreement”). Pursuant to the Voting Agreement, VNR and VNG agreed to vote the 20,924,055 ENP Common Units owned by VNG (representing approximately 45.6% of the outstanding ENP Common Units) in favor of the Merger and the adoption of the Merger Agreement at any meeting of ENP unitholders. VNR and VNG further agreed to not sell, transfer, assign, pledge, encumber, grant a participation in, gift-over, hypothecate or otherwise dispose of the 20,924,055 ENP Common Units owned by VNG. The Voting Agreement will terminate upon any termination of the Merger Agreement.

Cautionary Statements

The foregoing descriptions of the Merger Agreement and the Voting Agreement are qualified in their entirety by reference to the full text of the agreements (including the annexes thereto), which are attached hereto as Exhibits 2.1 and 10.1, respectively, and incorporated herein by reference.

The Merger Agreement is filed herewith to provide investors with information regarding its terms and is not intended to provide any other factual information about ENP or VNR. In particular, the assertions embodied in the representations and warranties contained in the Merger Agreement are as of specified dates and were made only for purposes of such Merger Agreement. Such representations and warranties are solely for the benefit of the parties to the Merger Agreement, and may be subject to limitations agreed between the parties. Moreover, certain representations and warranties in the Merger Agreement were used for the purpose of allocating risk among the parties thereto, rather than establishing matters as facts. Accordingly, they should not be relied upon as statements of factual information. Investors are not third-party beneficiaries under the Merger Agreement and should not rely on the representations and warranties in the Merger Agreement as characterizations of the actual state of facts about ENP or VNR. None of the representations and warranties contained in the Merger Agreement will have any legal effect among the parties to the Merger Agreement after the closing of the Merger.
