As previously disclosed, Vanguard Natural Resources, LLC (the “Company”) and certain subsidiaries (such subsidiaries, together with the Company, the “Debtors”) filed voluntary petitions for relief (the cases commenced thereby, the “Chapter 11 Cases”) under chapter 11 of the United States Bankruptcy Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of Texas (the “Bankruptcy Court”). The Chapter 11 Cases are being administered under the caption In re Vanguard Natural Resources, et al.

On March 20, 2017, Vanguard Operating, LLC, the Company’s wholly owned subsidiary and a Debtor (the “Seller”) entered into a purchase and sale agreement (the “PSA”) with OXY USA, Inc. (the “Buyer”). to the terms of the PSA, Seller agreed to sell a substantial portion of its oil and gas properties located in Glasscock County, Texas (the “Assets,” and such sale, the “Asset Sale”) for approximately $78.3 million in cash, subject to certain customary purchase price adjustments (the “Purchase Price”).

The Company has filed the PSA with the Bankruptcy Court along with a motion seeking, among other relief, the establishment of bidding procedures (the “Bidding Procedures Order”) for an auction that allows other qualified bidders to submit higher or otherwise better offers to purchase all or substantially all of the Assets (any such offer, a “Competing Transaction”). Subject to the receipt of qualified offers from other bidders proposing a Competing Transaction, the Debtors propose to hold an auction with respect to the Assets on or about May 2, 2017. Additional information regarding the proposed auction and the requirements for qualified bids with respect to a Competing Transaction can be found in the proposed Bidding Procedures Order.

Under the PSA, the Seller is responsible for payments to cure defaults, if any, under executory contracts that the Buyer elects to have assumed and assigned to it by the Seller. Following the entry of the Bidding Procedures Order (as defined below) by the Bankruptcy Court, the Buyer is obligated to make a deposit to an escrow account and upon the closing of the transactions contemplated by the PSA, the deposit will be released to the Seller and credited against the Purchase Price. The PSA contains customary representations, warranties and covenants. The parties expect to close the Asset Sale on May 5, 2017, subject to customary closing conditions, to the outcome of the proposed auction (provided that any qualified bids proposing a Competing Transaction are timely received) and to receipt of Bankruptcy Court approval. The PSA imposes post-closing indemnification obligations on the Seller for (i) claims and costs relating to the ownership of operation of the Assets prior to the closing of the Asset Sale, and (ii) assets excluded from the transactions contemplated by the PSA.

The PSA may be terminated, subject to certain exceptions: (i) upon mutual written consent; (ii) if the closing has not occurred by June 18, 2017; (iii) for material breaches by a party of representations and warranties or covenants that remain uncured; (iv) if the Bankruptcy Court does not enter the Bidding Procedures Order by April 19, 2017 or if the Bidding Procedures Order is amended, modified, or vacated in any manner without the Buyer’s consent; (v) if any governmental authority issues a non-appealable order restraining, enjoining or otherwise prohibiting the Asset Sale; (vi) if Seller selects or accepts a Competing Transaction as the highest or otherwise best bid made in accordance with the Bidding Procedures Order; (vii) if the Chapter 11 Cases are converted to Chapter 7, dismissed, or a trustee, receiver or examiner with expanded powers is appointed ; (viii) if the Bankruptcy Court does not enter an order authorizing the rejection of the Midland Basin Prospect Drilling and Development Agreement, dated May 9, 2014, by and among Vanguard Permian, LLC, Encore Energy Partners Operators, LLC and Athlon Holdings LP by May 19, 2017; and (ix) if the Bankruptcy Court does not authorize the sale of the Assets to the Buyer free and clear of certain claims and causes of action asserted in a complaint filed with the Bankruptcy Court by Encana Oil & Gas (USA) Inc. (“Encana”), or any amended complaint filed by May 19, 2017 with the Bankruptcy Court by Encana.

The summary of the PSA set forth above does not purport to be complete and is qualified in its entirety by reference to the PSA, which has been filed with the Bankruptcy Court and will be filed as an exhibit in our Quarterly Report on Form 10-Q for the period ended March 31, 2017.
