Item 1.01 Entry into a Material Definitive Agreement.

On February 20, 2015, LinnCo, LLC (the “Company”) entered into an Equity Distribution Agreement (the “Distribution Agreement”) with Citigroup Global Markets Inc., Credit Suisse Securities (USA) LLC, J.P. Morgan Securities LLC, Merrill Lynch, Pierce, Fenner & Smith Incorporated and UBS Securities LLC (collectively, the “Managers”). Pursuant to the terms of the Distribution Agreement, the Company may issue and sell from time to time through the Managers, as the Company’s sales agents, common shares representing limited liability company interests in the Company (the “Shares”) having an aggregate offering price of up to $500 million. Sales of the Shares, if any, made under the Distribution Agreement will be made by means of ordinary brokers’ transactions, through the facilities of The NASDAQ Global Select Market, any other national securities exchange or facility thereof, a trading facility of a national securities association or an alternate trading system, to or through a market maker or directly on or through an electronic communication network, a “dark pool” or any similar market venue, at market prices, in block transactions, or as otherwise agreed upon by the Managers and the Company. The Shares have been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a Registration Statement on Form S-3 (Registration No. 333-202217) (the “Registration Statement”) of the Company and Linn Energy, LLC (“LINN”), as supplemented by the Prospectus Supplement dated February 20, 2015 relating to the sale of the Shares, filed with the Securities and Exchange Commission pursuant to Rule 424(b)(5) of the Securities Act on February 20, 2015.

The Distribution Agreement contains customary representations and warranties of the parties and indemnification and contribution provisions under which the Company and the Managers have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act. The Company expects to use the net proceeds from any sale of the Shares to purchase from LINN, a number of units representing limited liability company interests in LINN (“LINN Units”) equal to the number of Shares sold pursuant to the Distribution Agreement. LINN will use the proceeds that it receives from the sale of LINN Units for general corporate purposes, which may include, among other things, capital expenditures, acquisitions and the repayment of debt. Affiliates of each of the Managers are lenders under LINN’s existing credit facilities. If LINN uses any proceeds from the sale of LINN Units to repay borrowings under its existing credit facilities, such affiliates will receive a portion of such proceeds.

The summary of the Distribution Agreement set forth in this Item 1.01 does not purport to be complete and is qualified by reference to such agreement, which is filed as Exhibit 1.1 hereto and incorporated herein and into the Registration Statement by reference. Legal opinions relating to the Shares are included as Exhibits 5.1 and 8.1 hereto and incorporated by reference into the Registration Statement.

(d) Exhibits.
