Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions (see General Instruction A.2. below):

On May 11, 2016, Linn Energy, LLC (the “Company”), LinnCo, LLC, an affiliate of the Company (“LinnCo”), certain of the Company’s direct and indirect subsidiaries (collectively with the Company, the “LINN Debtors”), and Berry Petroleum Company, LLC (“Berry” and, collectively with the LINN Debtors and LinnCo, the “Debtors”), filed voluntary petitions (the “Bankruptcy Petitions”) for reorganization 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 “Court”). The Debtors have filed a motion with the Court seeking joint administration of their Chapter 11 cases under the caption In re Linn Energy, LLC., et al., Case No. 16-60040 (the “Chapter 11 Cases”).

Prior to the filing of the Bankruptcy Petitions, on May 10, 2016, the Debtors entered into a restructuring support agreement (the “Restructuring Support Agreement”) with certain holders (the “Consenting Creditors”) collectively holding or controlling at least 66.67% by aggregate outstanding principal amounts under (i) the Company’s Sixth Amended and Restated Credit Agreement, dated as of April 24, 2013 (as amended, restated, supplemented or otherwise modified from time to time, the “LINN Credit Facility”) and (ii) Berry’s Second Amended and Restated Credit Agreement, dated as of November 15, 2010 (as amended, restated, supplemented or otherwise modified from time to time, the “Berry Credit Facility”).

The Restructuring Support Agreement sets forth, subject to certain conditions, the commitment of the Debtors and the Consenting Creditors to support a comprehensive restructuring of the Debtors’ long-term debt (the “Restructuring Transactions”). The Restructuring Transactions will be effectuated through one or more plans of reorganization (the “Plan”) to be filed in the Chapter 11 Cases.

The Company expects ordinary-course operations to continue substantially uninterrupted during and after the Chapter 11 Cases. The Restructuring Support Agreement provides that the Consenting Creditors will support the use of the LINN Debtors’ and Berry’s cash collateral under specified terms and conditions, including adequate protection terms.

Certain principal terms of the Plan are outlined below:

The New LINN Exit Facility will consist of (i) a term loan in the amount of $800 million (the “New LINN Term Loan”) and (ii) a revolving loan in the initial amount of $1.4 billion (the “New LINN Revolving Loan”). The New LINN Term Loan will mature on the earlier of June 30, 2021, or the day prior to the fourth anniversary of the date of emergence from bankruptcy (the “Closing Date”), with interest

payable at LIBOR plus 7.50% and amortized principal payments payable quarterly, beginning March 31, 2017. The New LINN Revolving Loan will be composed of two tranches as follows: (a) a Conforming Tranche with an initial amount of $1.2 billion subject to the Borrowing Base (the “Conforming Tranche”), and (b) a Non-Conforming Tranche with an initial amount of $200 million (the “Non-Conforming Tranche”). The Conforming Tranche will mature on the earlier of June 30, 2021, or the day prior to the fourth anniversary of the Closing Date, with an interest rate of LIBOR plus 3.50%. The Non-Conforming Tranche will mature on the earlier of December 31, 2020, or the day prior to the date that is three years and six months after the Closing, with an interest rate of LIBOR plus 5.50%. The New LINN Exit Facility is subject to a variety of other terms and conditions including conditions precedent to funding, financial covenants and various other covenants and representations and warranties.

The Plan will provide for the establishment of a customary management incentive plan at the Company and Berry under which no less than 10% of the New LINN Common Stock and New Berry Common Stock, respectively, will be reserved for grants made from time to time to the officers and other key employees of the respective reorganized entities. The Plan will provide for releases of specified claims held by the Debtors, the Consenting Creditors, and certain other specified parties against one another and for customary exculpations and injunctions.

The Restructuring Support Agreement obligates the Debtors and the Consenting Creditors to, among other things, support and not interfere with consummation of the Restructuring Transactions and, as to the Consenting Creditors, vote their claims in favor of the Plan. The Restructuring Support Agreement may be terminated upon the occurrence of certain events, including the failure to meet specified milestones relating to the filing, confirmation, and consummation of the Plan, among other requirements, and in the event of certain breaches by the parties under the Restructuring Support Agreement. The Restructuring Support Agreement is subject to termination if the effective date of the Plan has not occurred within 250 days of the filing of the Bankruptcy Petitions. There can be no assurances that the Restructuring Transactions will be consummated.

A copy of the Restructuring Support Agreement is attached hereto as Exhibit 10.1 to this Current Report on Form 8-K (this “Form 8-K”). The foregoing description of the Restructuring Support Agreement is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the Restructuring Support Agreement.

As described above, on May 11, 2016, the Debtors filed the Bankruptcy Petitions in the Court seeking relief under the provisions of Chapter 11 of the Bankruptcy Code. The Debtors will continue to operate their businesses as “debtors-in-possession” under the jurisdiction of the Court and in accordance with the applicable provisions of the Bankruptcy Code and orders of the Court.

Court filings and other information related to the Bankruptcy Petitions are available at a website administered by the Company’s claims agent, Prime Clerk LLC, at https://cases.primeclerk.com/linn.

The information set forth above in Item 1.01 of this Form 8-K is incorporated herein by reference.

The filing of the Bankruptcy Petitions described above in Item 1.03 constitutes an event of default that accelerated the Company’s and Berry’s respective obligations under the following debt instruments (the “Debt Instruments”):

The Debt Instruments provide that as a result of the Bankruptcy Petitions the principal and interest due thereunder shall be immediately due and payable. Any efforts to enforce such payment obligations under the Debt Instruments are automatically stayed as a result of the Bankruptcy Petitions, and the creditors’ rights of enforcement in respect of the Debt Instruments are subject to the applicable provisions of the Bankruptcy Code.

The Company, LinnCo, and Berry previously entered into confidentiality agreements with certain holders of the LINN Second Lien Notes and the Company’s and Berry’s unsecured notes (“Confidentiality Agreement Parties”). The Company entered into comprehensive restructuring negotiations with the Confidentiality Agreement Parties, which the Company expects to continue. The Confidentiality Agreement Parties have not reached agreement regarding the terms of a restructuring transaction.

Pursuant to the confidentiality agreements, the Company agreed to publicly disclose certain confidential information provided to the Confidentiality Agreement Parties (the “Cleansing Materials”). Copies of the Cleansing Materials, including (i) a diligence presentation provided to the Confidentiality Agreement Parties, (ii) a proposal from the Company to certain of its creditors (the “Company Proposal”) and (iii) a proposal from an ad hoc group of the holders of the Company’s senior unsecured notes (the “Unsecured Group Proposal”), are attached as Exhibit 99.1, Exhibit 99.2 and Exhibit 99.3, respectively, to this Form 8-K.

In addition, in connection with the filing of the Bankruptcy Petitions, the Company issued a press release on May 11, 2016, a copy of which is attached as Exhibit 99.4 to this Form 8-K.

Any financial projections or forecasts included in the Cleansing Materials were not prepared with a view toward public disclosure or compliance with the published guidelines of the Securities and Exchange Commission or the guidelines established by the American Institute of Certified Public Accountants regarding projections or forecasts. The projections do not purport to present the Company’s financial condition in accordance with accounting principles generally accepted in the United States. The Company’s independent accountants have not examined, compiled or otherwise applied procedures to the projections and, accordingly, do not express an opinion or any other form of assurance with respect to the projections. The inclusion of the projections therein should not be regarded as an indication that the Company or its affiliates or representatives consider the projections to be a reliable prediction of future events, and the projections should not be relied upon as such. Neither the Company nor any of its affiliates or representatives has made or makes any representation to any person regarding the ultimate outcome of the Company’s restructuring compared to the projections, and none of them undertakes any obligation to publicly update the projections to reflect circumstances existing after the date when the projections were made or to reflect the occurrence of future events, even in the event that any or all of the assumptions underlying the projections are shown to be in error.

The information included in this Form 8-K under Item 7.01 and Exhibit 99.1, Exhibit 99.2, Exhibit 99.3 and Exhibit 99.4 is being furnished and shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to liabilities of that Section, unless the registrant specifically states that the information is to be considered “filed” under the Exchange Act or incorporates it by reference into a filing under the Exchange Act or the Securities Act of 1933, as amended.
