Item 1.01. Entry into a Material Definitive Agreement.

As disclosed previously in its Current Report on Form 8-K filed on November 17, 2015, Linn Energy, LLC (the “Company”) and Linn Energy Finance Corp. (“Finance Corp.” and, together with the Company, the “Issuers”), entered into separate, privately-negotiated, exchange agreements (“Exchange Agreements”) with certain holders (“Holders”) of the Issuers’ outstanding 6.50% senior notes due May 2019 (the “6.50% 2019 Notes”), 6.25% senior notes due November 2019 (the “6.25% 2019 Notes”), 8.625% senior notes due April 2020 (the “2020 Notes”), 7.75% senior notes due February 2021 (the “7.75% 2021 Notes”) and 6.50% senior notes due September 2021 (the “6.50% 2021 Notes” and, together with the 6.50% 2019 Notes, the 6.25% 2019 Notes, the 2020 Notes and the 7.75% 2021 Notes, the “Exchanged Notes”). The Exchange Agreements provided that the Issuers will issue approximately $1.0 billion aggregate principal amount of the Issuers’ new 12.00% Senior Secured Second Lien Notes due 2020 (the “New Notes”), in exchange for approximately $2.0 billion aggregate principal amount of the Issuers’ Exchanged Notes held by such Holders.

In connection with the issuance of the New Notes and pursuant to the Exchange Agreements, on November 20, 2015, the Issuers and certain of the Company’s material domestic subsidiaries (the “Subsidiary Guarantors”) entered into an indenture (the “Indenture”) with U.S. Bank National Association, as trustee (the “Trustee”), pursuant to which the Issuers issued the New Notes in exchange for the Exchanged Notes.

The New Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities law and, unless so registered, may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. The New Notes are being offered only to persons who are qualified institutional buyers (as defined in Rule 144A under the Securities Act) in reliance on a private placement exemption from registration provided by Section 4(a)(2) under the Securities Act. Pursuant to the terms of the Exchange Agreements, the Company did not receive any proceeds from the issuance of the New Notes. Final closing settlements of the issuance of the New Notes are expected to be completed on or shortly after the original issuance date.

This Current Report on Form 8-K does not constitute an offer to sell, or a solicitation of an offer to buy, any security and shall not constitute an offer, solicitation or sale in any state or jurisdiction in which such offer, solicitation or sale would be unlawful.

The information included or incorporated by reference in Item 2.03 of this Report is incorporated by reference into this Item 1.01 of this Report.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement of a Registrant

Indenture, New Notes and Pledge Agreement

On November 20, 2015 (the “Settlement Date”), in exchange for an aggregate principal amount of approximately $2.0 billion of the Issuers’ Exchanged Notes, the Issuers issued New Notes in the aggregate principal amount of approximately $1.0 billion, and paid cash of approximately $9.7 million (which cash amount equals the accrued and unpaid interest on the Exchanged Notes exchanged up to, but excluding, the Settlement Date plus the amount of interest that would have been payable on such Exchanged Notes had such Exchanged Notes remained outstanding until November 19, 2015, and the amount paid in lieu of fractional New Notes in integrals less than $1,000), in exchange for the Exchanged Notes (the “Exchange”).

The New Notes are the senior secured obligations of the Company and the general unsecured obligations of Finance Corp. and will be secured by second-priority liens on all of the Company’s and Subsidiary Guarantors’ assets that secure that certain Sixth Amended and Restated Credit Agreement, dated as of April 24, 2013, among the Company, Wells Fargo Bank, National Association, as Administrative Agent, and the other lenders party thereto, as amended, supplemented or otherwise modified from time to time (the “Credit Facility”) (the “Collateral”), and rank effectively junior, pursuant to the terms of the Intercreditor Agreement described below, to any indebtedness of the Company secured on a priority basis to the New Notes, including indebtedness under the Credit Facility, to the extent of the value of the assets securing such indebtedness; rank equal with all senior indebtedness of the Issuers, without giving effect to any collateral arrangement, effectively senior to all unsecured senior indebtedness of the Company, to the extent of the value of the Collateral (after giving effect to any senior lien on the Collateral), and senior to all subordinated indebtedness of either of the Issuers. The New Notes are unconditionally guaranteed on a joint and several basis by the Subsidiary Guarantors. The guarantees are the senior secured obligations of each of the Subsidiary Guarantors and will be secured by second-priority liens on all of the Company’s and Subsidiary Guarantors’ Collateral, and rank effectively junior, pursuant to the terms of the Intercreditor Agreement, to any indebtedness of the applicable Subsidiary Guarantor secured on a priority basis to the guarantees, including indebtedness under the Credit Facility, to the extent of the value of the assets securing such indebtedness; rank equal with all senior indebtedness of the applicable Subsidiary Guarantor, without giving effect to any collateral arrangement, effectively senior to all unsecured senior indebtedness of the applicable Subsidiary Guarantor, to the extent of the value of the Collateral (after giving effect to any senior lien on the Collateral), and senior to all subordinated indebtedness of the applicable Subsidiary Guarantor. The New Notes and the guarantees are structurally junior to all indebtedness and other liabilities (including trade payables) of the Issuers’ subsidiaries that are not Subsidiary Guarantors.

Security for the Notes

The Collateral consists of (i) certain of the Company’s and the Subsidiary Guarantors’ oil and natural gas properties and other personal property, which will mortgaged during a period after the date of the Indenture as provided for therein, as well as (ii) a pledge of all ownership interests in the Subsidiary Guarantors pursuant to a Second Lien Pledge Agreement entered into on November 20, 2015 (the “Pledge Agreement”), between the Company, the Subsidiary Guarantors and U.S. Bank National Association, as the collateral trustee (the “Collateral Trustee”).

Interest and Maturity

The New Notes will mature on December 15, 2020, subject to a “springing maturity date” ahead of junior lien or unsecured indebtedness if more than $250 million of a particular series of such indebtedness is outstanding 92 days prior to their respective maturities, and will bear interest at a rate of 12.00% per year, payable semiannually in arrears on June 15 and December 15 of each year, beginning on June 15, 2016. The Company will pay additional interest, if any, at a rate equal to 0.25% per annum during the 90-day period immediately following the occurrence of any registration default pursuant to the terms of the Registration Rights Agreements (as described below), which shall increase by 0.25% per annum at the end of each subsequent 90-day period, but in no event shall such increase exceed 1.00% per annum.

Optional Redemption

At any time prior to December 15, 2018, the Issuers may on one or more occasions redeem up to 35% of the aggregate principal amount of New Notes issued under the Indenture at a redemption price of 112.00% of the

principal amount, plus accrued and unpaid interest and Additional Interest (as defined in the Indenture), if any, to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), using the net cash proceeds of one or more equity offerings by the Company, provided that:

Prior to December 15, 2018, the Issuers may redeem all or part of the New Notes upon not less than 30 or more than 60 days’ notice, at a redemption price equal to the sum of:

On and after December 15, 2018, the Issuers have the option to redeem all or a part of the New Notes, upon not less than 30 or more than 60 days’ notice, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest and Additional Interest, if any, to the applicable redemption date, on the New Notes redeemed to the applicable redemption date (subject to the right of holders of record on the relevant record date to receive interest due on an interest payment date that is on or prior to the redemption date), if redeemed during the twelve-month period beginning on December 15 of the years indicated below:

Change of Control

If the Company undergoes a Change of Control (as defined in the Indenture), holders of New Notes may require the Company to repurchase for cash all or part of their New Notes at a repurchase price equal to 101% of the aggregate principal amount of the New Notes to be repurchased, plus accrued and unpaid interest and Additional Interest, if any, thereon to the date of settlement.

Certain Covenants

The Indenture contains covenants that, among other things, limit the Issuers’ ability and the ability of the Company’s restricted subsidiaries to: (i) declare or pay distributions on, purchase or redeem the Company’s units or purchase or redeem the Company’s or its restricted subsidiaries’ indebtedness secured by liens junior in priority to liens securing the New Notes, unsecured indebtedness or subordinated indebtedness; (ii) make investments; (iii) incur or guarantee additional indebtedness or issue certain types of equity securities; (iv) create

certain liens; (v) sell assets; (vi) consolidate, merge or transfer all or substantially all of the Issuers’ assets; (vii) enter into agreements that restrict distributions or other payments from the Company’s restricted subsidiaries to the Company; (viii) engage in transactions with affiliates; and (ix) create unrestricted subsidiaries. These covenants are subject to a number of exceptions and qualifications. If at any time the New Notes are rated investment grade by both Standard & Poor’s Ratings Services and Moody’s Investor’s Services, Inc. and no default has occurred and is continuing under the Indenture, certain of the covenants and related Events of Default (as defined in the Indenture) will be terminated, and the Company and its restricted subsidiaries will no longer be subject to such covenants and Events of Default.

Events of Default

Upon a continuing event of default, the trustee or the holders of 25% of the principal amount of the New Notes may declare the New Notes immediately due and payable, except that a default resulting from a bankruptcy, insolvency or reorganization with respect to the Issuers, any restricted subsidiary of the Company that is a significant subsidiary or any group of its restricted subsidiaries that, taken together, would constitute a significant subsidiary of the Company, will automatically cause all New Notes to become due and payable. Each of the following constitutes an “Event of Default” under the Indenture:

The foregoing descriptions of the Indenture, the New Notes and the Pledge Agreement do not purport to be complete and are qualified in their entirety by reference to the Indenture and the Pledge Agreement, which are filed as Exhibits 4.1 and 10.1, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.

Registration Rights Agreement

On November 20, 2015, the Issuers and the Subsidiary Guarantors entered into a Registration Rights Agreement with each of the Holders (collectively, the “Registration Rights Agreements”), pursuant to the terms of the Exchange Agreements. Under the Registration Rights Agreements, the Issuers and the Subsidiary Guarantors agreed to use their commercially reasonable efforts to file with the United States Securities and Exchange Commission and cause to become effective a registration statement relating to an offer to issue new notes having terms substantially identical to the New Notes in exchange for outstanding New Notes within 370 days after the notes were issued. In certain circumstances, the Issuers and the Subsidiary Guarantors may be required to file a shelf registration statement to cover resales of the New Notes. The Issuers and the Subsidiary Guarantors will be obligated to file one or more registration statements as described above only if the restrictive legend on the New Notes has not been removed (other than with respect to persons that are affiliates of the Company) and the New Notes are not freely tradable (by persons other than the Company’s affiliates) pursuant to Rule 144 under the Securities Act of 1933, as amended, as of the 370th day after the notes were issued. If the Issuers and the Subsidiary Guarantors fail to satisfy these obligations, the Company may be required to pay additional interest to holders of the New Notes under certain circumstances.

The foregoing description of the Registration Rights Agreements does not purport to be complete and is qualified in its entirety by reference to the form of Registration Rights Agreement, which is filed as Exhibit 10.2 to this Current Report on Form 8-K and is incorporated herein by reference.
