Any certificate signed by any officer of the Company or the Parent and delivered to the Representatives or counsel for the Underwriters in connection with the offering of the Offered Shares and Purchased Units shall be deemed a representation and warranty by the Company or the Parent, as applicable, as to matters covered thereby, to each Underwriter.

2. Purchase of the Offered Shares by the Underwriters. On the basis of the representations, warranties and covenants contained in, and subject to the terms and conditions of, this Agreement, the Company agrees to sell 30,250,000 Firm Shares to the several Underwriters, and each of the Underwriters, severally and not jointly, agrees to purchase the number of Firm Shares set forth opposite that Underwriter’s name in Schedule I hereto. The respective purchase obligations of the Underwriters with respect to the Firm Shares shall be rounded among the Underwriters to avoid fractional shares, as the Representatives may determine.

In addition, the Company grants to the Underwriters an option to purchase up to 4,537,500 Option Shares. Such option is exercisable in the event that the Underwriters sell more Common Shares than the number of Firm Shares in the offering and as set forth in Section 4 hereof. Each Underwriter agrees, severally and not jointly, to purchase the number of Option Shares (subject to such adjustments to eliminate fractional shares as the Representatives may determine) that bears the same proportion to the total number of Option Shares to be sold on such Delivery Date as the number of Firm Shares set forth in Schedule I hereto opposite the name of such Underwriter bears to the total number of Firm Shares.

The purchase price payable by the Underwriters for both the Firm Shares and any Option Shares is $34.995 per share.

The Company is not obligated to deliver any of the Firm Shares or Option Shares to be delivered on the applicable Delivery Date, except upon payment for all such Offered Shares to be purchased on such Delivery Date as provided herein.

3. Offering of Offered Shares by the Underwriters. Upon authorization by the Representatives of the release of the Firm Shares, the several Underwriters propose to offer the Firm Shares for sale upon the terms and conditions to be set forth in the Prospectus.

This date and time are sometimes referred to as the “Initial Delivery Date.” Delivery of the Firm Shares shall be made to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives to or upon the order of the Company of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. The Company shall deliver the Firm Shares through the facilities of the Depository Trust Company (the “DTC”) unless the Representatives shall otherwise instruct.

The option granted in Section 2 will expire 30 days after the date of this Agreement and may be exercised in whole or from time to time in part by written notice being given to the Company by the Representatives; provided that if such date falls on a day that is not a business day, the option granted in Section 2 will expire on the next succeeding business day. Such notice shall set forth the aggregate number of Option Shares as to which the option is being exercised, the names in which the Option Shares are to be registered, the denominations in which the Option Shares are to be issued and the date and time, as determined by the Representatives, when the Option Shares are to be delivered; provided, however, that this date and time shall not be earlier than the Initial Delivery Date nor earlier than the third business day after the date on which the option shall have been exercised (or, if the Option Shares are to be delivered on the Initial Delivery Date, not earlier than the second business day after the date on which the option shall have been exercised), nor later than the fifth business day after the date on which the option shall have been exercised. Each date and time the Option Shares are delivered is sometimes referred to as an “Option Shares Delivery Date,” and the Initial Delivery Date and any Option Shares Delivery Date are sometimes each referred to as a “Delivery Date.”

Delivery of the Option Shares by the Company and payment for the Option Shares by the several Underwriters through the Representatives shall be made at 10:00 A.M., New York City time, on the date specified in the corresponding notice described in the preceding paragraph or at such other date or place as shall be determined by agreement between the Representatives and the Company. On the Option Shares Delivery Date, the Company shall deliver or cause to be delivered the Option Shares to the Representatives for the account of each Underwriter against payment by the several Underwriters through the Representatives of the purchase price by wire transfer in immediately available funds to the accounts specified by the Company. Time shall be of the essence, and delivery at the time and place specified pursuant to this Agreement is a further condition of the obligation of each Underwriter hereunder. The Company shall deliver the Option Shares through the facilities of DTC unless the Representatives shall otherwise instruct.

or action relating to purchases and sales of Offered Shares), to which that Underwriter, affiliate, director, officer, employee, controlling person or agent may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) any Preliminary Prospectus, the Registration Statement, the Prospectus or in any amendment or supplement thereto, (B) any Issuer Free Writing Prospectus or in any amendment or supplement thereto, (C) any Permitted Issuer Information used or referred to in any “free writing prospectus” (as defined in Rule 405 under the Securities Act) used or referred to by any Underwriter, (D) any materials or information provided to investors by, or with the approval of, the Company in connection with the marketing of the offering of the Offered Shares, including any “road show” (as defined in Rule 433 under the Securities Act) not constituting an Issuer Free Writing Prospectus (“Marketing Materials”), or (E) any Blue Sky application or other document prepared or executed by the Company (or based upon any written information furnished by the Company for use therein) specifically for the purpose of qualifying any or all of the Offered Shares or the Purchased Units under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, and shall reimburse each Underwriter and each such affiliate, director, officer, employee, controlling person or agent promptly upon demand for any legal or other out-of-pocket expenses reasonably incurred by that Underwriter, affiliate, director, officer, employee, controlling person or agent in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company and the Parent shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Permitted Issuer Information, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company and the Parent through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 8(e). The foregoing indemnity agreement is in addition to any liability which the Company or the Parent may otherwise have to any Underwriter or to any affiliate, director, officer, employee, controlling person or agent of that Underwriter.

(b) Each Underwriter, severally and not jointly, shall indemnify and hold harmless the Company and the Parent, its respective directors (including any person who, with his or her consent, is named in the Registration Statement as about to become a director of the Company), officers and employees, and each person, if any, who controls the Company or the Parent within the meaning of Section 15 of the Securities Act or

Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Company, the Parent or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, or (ii) the omission or alleged omission to state in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials or Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Underwriter furnished to the Company or the Parent through the Representatives by or on behalf of that Underwriter specifically for inclusion therein, which information is limited to the information set forth in Section 8(e). The foregoing indemnity agreement is in addition to any liability that any Underwriter may otherwise have to the Company, the Parent or any such director, officer, employee or controlling person.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 8 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 8. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 8 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees, controlling persons and agents who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 8 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party and its directors, officers,

employees, controlling persons and agents shall have reasonably concluded that there may be legal defenses available to them that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties or their respective directors, officers, employees, controlling persons or agents, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld, conditioned or delayed), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld, conditioned or delayed), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(d) If the indemnification provided for in this Section 8 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 8(a) or 8(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Company and the Parent, on the one hand, and the Underwriters, on the other, from the offering of the Offered Shares, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Company or the Parent, on the one hand, and the Underwriters, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Company and the Parent, on the one hand, and the Underwriters, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Shares purchased under this Agreement (before deducting expenses) received by the Company, as set forth in the table on the cover page of the Prospectus, on the one hand, and the total underwriting discounts and commissions received by the Underwriters with respect to the Offered Shares purchased under this Agreement, as set forth in the table on the cover page of the Prospectus, on the other hand. The relative fault shall be determined by reference to whether the untrue or alleged untrue statement of a material fact or omission or alleged

omission to state a material fact relates to information supplied by the Company, the Parent or the Underwriters, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, the Parent and the Underwriters agree that it would not be just and equitable if contributions pursuant to this Section 8(d) were to be determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 8(d) shall be deemed to include, for purposes of this Section 8(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 8(d), in no event shall an Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Offered Shares exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective underwriting obligations and not joint.

(e) The Underwriters severally confirm and each of the Company and the Parent acknowledges and agrees that the statements regarding delivery of Offered Shares by the Underwriters set forth on the cover page of, and the concession and reallowance figures and the paragraph relating to stabilization by the Underwriters appearing under the caption “Underwriting” in, the most recent Preliminary Prospectus and the Prospectus are correct and constitute the only information concerning such Underwriters furnished in writing to the Company or the Parent by or on behalf of the Underwriters specifically for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Marketing Materials.

(f) Without limitation of and in addition to its obligations under the other paragraphs of this Section 8, each of the Company and the Parent agrees to indemnify and hold harmless Barclays Capital Inc. (in the capacity described in this paragraph, the “Independent Underwriter”), its affiliates, directors, officers and employees. each person who controls the Independent Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any agent of Barclays Capital Inc. from and against any and all loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of Stock) to which the Independent Underwriter, affiliate, director, officer, employee, controlling person or agent may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, the Independent Underwriter’s acting as a “qualified independent underwriter” (within the meaning of FINRA Rule 5121) in

connection with the offering contemplated by this Agreement, and agrees to reimburse each such indemnified party promptly upon demand for any legal or other expenses reasonably incurred by them in connection with investigating or defending or preparing to defend any such loss, claim, damage, liability or action; provided, however, that the Company and the Parent shall not be liable in any such case to the extent that it is determined in a final judgment by a court of competent jurisdiction that such loss, claim, damage, liability or action resulted directly from the gross negligence or willful misconduct of the Independent Underwriter. The relative benefits received by the Independent Underwriter with respect to the offering contemplated by this Agreement shall, for purposes of Section 10(e), be deemed to be equal to the compensation received by the Independent Underwriter for acting in such capacity. In addition, notwithstanding the provisions of Section 10(e), the Independent Underwriter shall not be required to contribute any amount in excess of the compensation received by the Independent Underwriter for acting in such capacity.

(a) If, on any Delivery Date, any Underwriter defaults in its obligations to purchase the Offered Shares that it has agreed to purchase under this Agreement, the remaining non-defaulting Underwriters may in their discretion arrange for the purchase of such Offered Shares by the non-defaulting Underwriters or other persons satisfactory to the Company on the terms contained in this Agreement. If, within 36 hours after any such default by any Underwriter, the non-defaulting Underwriters do not arrange for the purchase of such Offered Shares, then the Company shall be entitled to a further period of 36 hours within which to procure other persons satisfactory to the non-defaulting Underwriters to purchase such Offered Shares on such terms. In the event that within the respective prescribed periods, the non-defaulting Underwriters notify the Company that they have so arranged for the purchase of such Offered Shares, or the Company notifies the non-defaulting Underwriters that it has so arranged for the purchase of such Offered Shares, either the non-defaulting Underwriters or the Company may postpone such Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Company or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement, and the Company and the Parent agree to promptly prepare any amendment or supplement to the Registration Statement, the Prospectus or in any such other document or arrangement that effects any such changes. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 9, purchases Offered Shares that a defaulting Underwriter agreed but failed to purchase.

(b) If, after giving effect to any arrangements for the purchase of the Offered Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the total number of Offered Shares that remains unpurchased does not exceed one-eleventh of the total number of shares of all the Offered Shares, then the Company shall have the right to require each non-defaulting Underwriter to purchase the total number of Offered Shares that such Underwriter agreed to purchase hereunder plus such Underwriter’s pro rata share (based on the total number of

Offered Shares that such Underwriter agreed to purchase hereunder) of the Offered Shares of such defaulting Underwriter or Underwriters for which such arrangements have not been made; provided that the non-defaulting Underwriters shall not be obligated to purchase more than 110% of the total number of Offered Shares that it agreed to purchase on such Delivery Date pursuant to the terms of Section 2.

(c) If, after giving effect to any arrangements for the purchase of the Offered Shares of a defaulting Underwriter or Underwriters by the non-defaulting Underwriters and the Company as provided in paragraph (a) above, the total number of Offered Shares that remains unpurchased exceeds one-eleventh of the total number of all Offered Shares, or if the Company shall not exercise the right described in paragraph (b) above, then this Agreement shall terminate without liability on the part of the non-defaulting Underwriters. Any termination of this Agreement pursuant to this Section 9 shall be without liability on the part of the Company, except that the Company will continue to be liable for the payment of expenses as set forth in Sections 6 and 11 and except that the provisions of Section 6 shall not terminate and shall remain in effect.

(d) Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Company or any non-defaulting Underwriter for damages caused by its default.

10. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Firm Shares if, prior to that time, any of the events described in Sections 7(n) and 7(o) shall have occurred or if the Underwriters shall decline to purchase the Offered Shares for any reason permitted under this Agreement. In the event of a termination pursuant to this Section 10, the Company shall have no obligation to pay the structuring fee set forth in Section 6.

11. Reimbursement of Underwriters’ Expenses. If (a) the Company shall fail to tender the Offered Shares for delivery to the Underwriters for any reason, or (b) the Underwriters shall decline to purchase the Offered Shares for any reason permitted under this Agreement, the Company and the Parent will reimburse the Underwriters for all reasonable out-of-pocket expenses (including fees and disbursements of counsel for the Underwriters) incurred by the Underwriters in connection with this Agreement and the proposed purchase of the Offered Shares, and upon demand the Company and the Parent shall pay the full amount thereof to the Representatives. If this Agreement is terminated pursuant to Section 7(o) (other than Section 7(o)(ii)) or Section 9 by reason of the default of one or more Underwriters, the Company and the Parent shall not be obligated to reimburse any Underwriter on account of those expenses.

12. Research Analyst Independence. Each of the Company and the Parent acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Company and the Parent or the Offering that differ from the views of their respective investment banking divisions. Each of the Company and the Parent hereby waives

and releases, to the fullest extent permitted by law, any claims that the Company or the Parent may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company or the Parent by such Underwriters’ investment banking divisions. Each of the Company and the Parent acknowledges that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the Linn Parties that may be the subject of the transactions contemplated by this Agreement.

13. No Fiduciary Duty. Each of the Company and the Parent acknowledges and agrees that in connection with the Offering, the sale of the Offered Shares or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (a) no fiduciary or agency relationship between the Company or the Parent and any other person, on the one hand, and the Underwriters, on the other, exists; (b) the Underwriters are not acting as advisors, expert or otherwise, to the Company or the Parent, including, without limitation, with respect to the determination of the public offering price of the Offered Shares, and such relationship between the Company or the Parent, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (c) any duties and obligations that the Underwriters may have to the Company or the Parent shall be limited to those duties and obligations specifically stated herein; and (d) the Underwriters and their respective affiliates may have interests that differ from those of the Company or the Parent. Each of the Company and the Parent hereby waives any claims that the Company or the Parent may have against the Underwriters with respect to any breach of fiduciary duty in connection with the Offering.

The undersigned understands that you and certain other firms (the “Underwriters”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) providing for the purchase by the Underwriters of shares of common shares representing limited liability company interests (the “Common Shares”), of LinnCo, LLC, a Delaware limited liability company (the “Company”), and that the Underwriters propose to reoffer (the “Offering”) the Common Shares to the public (the “Offered Shares”).

It is understood and agreed by all parties that the Company was recently formed by Linn Energy, LLC, a Delaware limited liability company (the “Parent”), with the sole purpose to own common units representing limited liability company interests in Parent (the “Units”). The Parent is a publicly traded limited liability company and is listed on the NASDAQ Global Select Market.

In consideration of the execution of the Underwriting Agreement by the Underwriters, and for other good and valuable consideration, the undersigned hereby irrevocably agrees that, without the prior written consent of Barclays Capital Inc., on behalf of the Underwriters, the undersigned will not, directly or indirectly, (1) offer for sale, sell, pledge, or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of) any Common Shares or Units (including, without limitation, Common Shares or Units that may be deemed to be beneficially owned by the undersigned in accordance with the rules and regulations of the Securities and Exchange Commission and Common Shares or Units that may be issued upon exercise of any options or warrants) or securities convertible into or exercisable or exchangeable for Common Shares or Units (other than transfers of Common Shares or Units as bona fide gifts; provided that in the case of any such transfer, each donee shall execute and deliver to

Barclays Capital Inc. a lock-up letter in the form of this agreement), (2) enter into any swap or other derivatives transaction that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of Common Shares or Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Shares, Units or other securities, in cash or otherwise, (3) make any demand for or exercise any right or cause to be filed a registration statement, including any amendments thereto, with respect to the registration of any Common Shares, Units or securities convertible into or exercisable or exchangeable for Common Shares, Units or any other securities of the Company or the Parent, or (4) publicly disclose the intention to do any of the foregoing for a period commencing on the date hereof and ending on the 180th day (in the case of the Common Shares) or the 90th day (in the case of the Units) after the date of the Prospectus relating to the Offering (each such period, the “Lock-Up Period”). Notwithstanding anything herein to the contrary, the foregoing sentence does not apply to (i) vesting of restricted units or net exercises of options to purchase Units or (ii) withholding of Units to pay income taxes upon the vesting of restricted Units under the Parent’s long-term incentive plan in effect on the date hereof.

If the undersigned is an officer or director of the Company or the Parent, (i) Barclays Capital Inc. agrees that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of Common Shares or Units, Barclays Capital Inc. will notify the Company and the Parent of the impending release or waiver, and (ii) the Company and the Parent have agreed in the Underwriting Agreement to announce the impending release or waiver by issuing a press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Barclays Capital Inc. hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if both (a) the release or waiver is effected solely to permit a transfer not for consideration, and (b) the transferee has agreed in writing to be bound by the same terms described in this letter that are applicable to the transferor, to the extent and for the duration that such terms remain in effect at the time of the transfer.

Notwithstanding the foregoing, if (1) during the last 17 days of the Lock-Up Period, the Company or the Parent issues an earnings release or material news or a material event relating to the Company or the Parent occurs, or (2) prior to the expiration of the Lock-Up Period, the Company or the Parent announces that it will release earnings results during the 16-day period beginning on the last day of the Lock-Up Period, then the restrictions imposed by this Lock-Up Letter Agreement shall continue to apply until the expiration of the 18-day period beginning on the issuance of the earnings release or the announcement of the material news or the occurrence of the material event, unless Barclays Capital Inc. agrees not to require such extension in writing. The undersigned hereby further agrees that, prior to engaging in any transaction or taking any other action that is subject to the terms of this Lock-Up Letter Agreement during the period from the date of this Lock-Up Letter Agreement to and including the 34^th day following the expiration of the Lock-Up Period, it will give notice thereof to the Company and the

Parent and will not consummate such transaction or take any such action unless it has received written confirmation from the Company or the Parent that the Lock-Up Period (as such may have been extended pursuant to this paragraph) has expired. The foregoing sentence shall not apply to bona fide gifts, sales or other dispositions of shares of any class of the Common Shares or the Units, in each case that are made exclusively between and among the undersigned or members of the undersigned’s family, or affiliates of the undersigned, including its partners (if a partnership) or members (if a limited liability company); provided that it shall be a condition to any such transfer that (i) the transferee/donee agrees to be bound by the terms of this Lock-Up Letter Agreement (including, without limitation, the restrictions set forth in the preceding sentence) to the same extent as if the transferee/donee were a party hereto, (ii) no filing by any party (donor, donee, transferor or transferee) under, shall be required or shall be voluntarily made in connection with such transfer or distribution (other than a filing on a Form 5, Schedule 13D or Schedule 13G (or 13D-A or 13G-A) made after the expiration of the applicable period referred to above), (iii) each party (donor, donee, transferor or transferee) shall not be required by law (including without limitation the disclosure requirements of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended) to make, and shall agree to not voluntarily make, any public announcement of the transfer or disposition, and (iv) the undersigned notifies Barclays Capital Inc. at least two business days prior to the proposed transfer or disposition.

In furtherance of the foregoing, the Company, the Parent and their transfer agent are hereby authorized to decline to make any transfer of securities if such transfer would constitute a violation or breach of this Lock-Up Letter Agreement.

It is understood that, if the Company or the Parent notifies the Underwriters that it does not intend to proceed with the Offering, if the Underwriting Agreement does not become effective, or if the Underwriting Agreement (other than the provisions thereof which survive termination) shall terminate or be terminated prior to payment for and delivery of the Offered Shares, the undersigned will be released from its obligations under this Lock-Up Letter Agreement.

The undersigned understands that the Company, the Parent and the Underwriters will proceed with the Offering in reliance on this Lock-Up Letter Agreement.

Whether or not the Offering actually occurs depends on a number of factors, including market conditions. Any Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company, the Parent and the Underwriters.

This Lock-Up Letter Agreement shall automatically terminate upon the earliest to occur, if any, of (1) the Underwriters, on the one hand, or the Company or the Parent, on the other hand, advising the other in writing, prior to the execution of the Underwriting Agreement, that they have determined not to proceed with the Offering, (2) termination of the Underwriting Agreement before the sale of any Offered Shares to the Underwriters or (3) December 15, 2012, in the event that the Underwriting Agreement has not been executed by that date.

The undersigned hereby represents and warrants that the undersigned has full power and authority to enter into this Lock-Up Letter Agreement and that, upon request, the undersigned will execute any additional documents necessary in connection with the enforcement hereof. Any obligations of the undersigned shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned.


Very truly yours,

[LinnCo, LLC][Linn Energy, LLC], (the “Company”) announced today that Barclays Capital Inc., the lead book-running manager in the Company’s recent public sale of [ — ] [Common Shares][Units] is [waiving] [releasing] a lock-up restriction with respect to [ — ] of the Company’s [Common Shares][Units] held by [certain officers or directors] [an officer or director] of the Company. The [waiver] [release] will take effect on [insert date], and the [shares][units] may be sold or otherwise disposed of on or after such date.

This press release is not an offer for sale of the securities in the United States or in any other jurisdiction where such offer is prohibited, and such securities may not be offered or sold in the United States absent registration or an exemption from registration under the United States Securities Act of 1933, as amended.

1. Each of the Company, the Parent and the Parent’s subsidiaries that are incorporated or organized in the State of Delaware (the “DE Subsidiaries”) is validly existing and in good standing as a corporation or limited liability company, as applicable, under the laws of the State of Delaware, and is duly qualified to do business and in good standing as a foreign corporation or limited liability company, as applicable, in each of the other jurisdictions listed on Exhibit A to such opinion.

2.(a) Each of the Company and the Parent has the limited liability company power to execute and deliver, and perform its obligations under, this Agreement and (b) each of the Company, the Parent and the DE Subsidiaries has the corporate or limited liability company power, as applicable, to own, lease and operate its property and conduct its business as described in the Pricing Disclosure Package and the Prospectus. The Company has the limited liability company power to authorize, issue, sell and deliver the Offered Shares to be issued and sold to the Underwriters pursuant to this Agreement. The Parent has the limited liability company power to authorize, issue, sell and deliver the Purchased Units pursuant to the LNCO LLC Agreement.

3. This Agreement has been duly and validly authorized, executed and delivered by the Company and the Parent.

4. The Offered Shares to be issued and sold by the Company to the Underwriters pursuant to this Agreement have been duly authorized in accordance with the LNCO LLC Agreement and, upon payment therefor and delivery thereof in accordance with this Agreement, will be validly issued, fully paid (to the extent required under the LNCO LLC Agreement) and non-assessable (except as such non-assessability may be affected by Sections 18-607 and 18-804 of the Delaware LLC Act) and will conform in all material respects to the description thereof contained in the Pricing Disclosure Package and the Prospectus. The voting share of the Company issued to the Parent conforms in all material respects to the description thereof contained in the Pricing Disclosure Package and the Prospectus.

5. The Purchased Units to be issued and sold by the Parent to the Company pursuant to the LNCO LLC Agreement have been duly authorized in accordance with the Linn LLC Agreement and, upon payment therefor and delivery thereof as contemplated in the Pricing Disclosure Package and the Prospectus, will be validly issued, fully paid (to the extent required under the Linn LLC Agreement) and non-assessable (except as such non-assessability may be affected by Sections 18-607 and 18-804 of the Delaware LLC Act) and will conform in all material respects to the description thereof contained in the Pricing Disclosure Package and the Prospectus.

6. The Delaware LLC Act does not grant holders of Common Shares or Units preemptive rights to subscribe for or purchase the Offered Shares or the Purchased Units, respectively. Except as described in the Pricing Disclosure Package and the Prospectus, there are no preemptive or other rights to subscribe for or to purchase, nor any restriction upon the voting

or transfer of, any of the Offered Shares or Purchased Units pursuant to any of the Company’s certificate of formation, the Parent’s certificate of formation, the LNCO LLC Agreement, the Linn LLC Agreement or the agreements filed as exhibits to the Parent’s Annual Report on Form 10-K for the year ended December 31, 2011, Quarterly Reports on Form 10-Q for the quarters ended March 31, 2012 and June 30, 2012 and any Current Reports on Form 8-K filed since June 30, 2012 until the date hereof (collectively, the “Reviewed Agreements”).

7. The execution and delivery of this Agreement by the Company and the Parent, the consummation of the transactions contemplated by this Agreement and the application of the proceeds from the sale of the Offered Shares and the Purchased Units described under “Use of Proceeds” in each of the Pricing Disclosure Package and the Prospectus do not, and the performance by the Company and the Parent of their respective obligations under this Agreement will not, (a) result in any violation of the Linn LLC Agreement or the LNCO LLC Agreement, (b) result in any violation or breach of or result in a default (or an event which with notice or lapse of time, or both, would constitute a default) under, or result in the creation or imposition of any lien, charge or encumbrance upon any property or assets of the Company or the Parent under, the Reviewed Agreements or (c) result in any violation of any law, statute, order, rule or regulation known to us of any court or governmental agency or body or under the Delaware LLC Act, the Delaware General Corporation Law (the “DGCL”) or United States federal law (the “Included Laws”); provided that such counsel may state that they do not express any opinion in this paragraph 7 as to federal or state securities or anti-fraud laws.

8. No authorization or approval or other action by, and no notice to or filing with, any governmental authority or regulatory body (each, a “Filing”) is required under any of the Included Laws for the due execution and delivery of this Agreement by the Company or the Parent and the performance by the Company or the Parent of their respective obligations under this Agreement, except for (a) routine Filings necessary in connection with the conduct of the business of the Company, the Parent and its subsidiaries, including routine Filings required to be made under the Exchange Act, (b) such other Filings as have been obtained or made, (c) such Filings required under the Securities Act or the Exchange Act as provided in this Agreement, (d) Filings required to maintain corporate and similar standing and existence and (e) Filings required to be made under state securities or blue sky laws, antifraud laws and the rules and regulations of the Financial Industry Regulatory Authority, Inc.

9. The statements in each of the Pricing Disclosure Package and the Prospectus under the caption “Material U.S. Federal Income Tax Consequences,” insofar as such statements constitute a summary of the United States federal tax laws referred to therein, as of the Applicable Time and the date of the Prospectus, are accurate in all material respects and fairly summarize the United States federal tax laws referred to therein, subject to the qualifications and assumptions stated therein; and the opinion of such counsel that was filed as Exhibit 8.1 to the Registration Statement on September 24, 2012 is confirmed, and the Underwriters may rely upon such opinion as if it were addressed to them.

10. The Registration Statement has become effective under the Securities Act and the Prospectus has been filed with the Commission pursuant to Rule 424(b) under the Securities Act. To such counsel’s knowledge, no stop order suspending the effectiveness of the Registration Statement has been issued under the Securities Act and no proceedings therefor have been initiated or threatened by the Commission.

11. The statements in each of the Pricing Disclosure Package and the Prospectus under the captions “Prospectus Summary,” “Our Dividend Policy,” “Certain Relationships and Related Transactions,” “Description of Our Shares,” “Description of the LINN Units,” and “Description of the Limited Liability Company Agreements” insofar as such statements purport to summarize the legal terms of the Shares and the Units (including the Offered Shares and the Purchased Units), the LNCO LLC Agreement, the Linn LLC Agreement and the Omnibus Agreement are accurate in all material respects, subject to the qualifications and assumptions stated therein. The statements in each of the Pricing Disclosure Package and the Prospectus under the captions “Business—LINN—Environmental Matters and Regulation” and “ERISA Considerations,” insofar as such statements purport to summarize provisions of United States federal laws referred to therein, are accurate in all material respects, subject to the qualifications and assumptions stated therein. The statements in the Pricing Disclosure Package and the Prospectus under the caption “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources,” insofar as such statements purport to summarize provisions of contracts or agreements referred to therein, are accurate in all material respects, subject to the qualifications and assumptions stated therein.

12. The Company, the Parent and its subsidiaries are not, and after giving effect to the offering and sale of the Offered Shares and the Purchased Units contemplated by this Agreement and the application of the net proceeds from such sale as described in the Pricing Disclosure Package and the Prospectus, the Company, the Parent and its subsidiaries will not be, required to register as an “investment company,” as such term is defined under the Investment Company Act.

13. The LNCO LLC Agreement has been duly authorized, executed and delivered by the Company and the Parent and is a valid and legally binding agreement of the Company and the Parent, enforceable against the Company and the Parent, in accordance with its terms; provided that the enforceability thereof is subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting the rights and remedies of creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.

14. The Linn LLC Agreement has been duly authorized, executed and delivered by the Parent and is a valid and legally binding agreement of the Parent, enforceable against the Parent in accordance with its terms; provided that the enforceability thereof is subject to (i) applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting the rights and remedies of creditors’ rights generally and by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (ii) public policy, applicable law relating to fiduciary duties and indemnification and contribution and an implied covenant of good faith and fair dealing.

In rendering such opinion, such counsel may (A) with respect to the opinion expressed in paragraph 1 above as it relates to the valid existence and good standing of the Company, the

Parent and the DE Subsidiaries under the laws of the State of Delaware, rely solely upon certificates from the Secretary of State of the State of Delaware, (B) with respect to the opinion expressed in paragraph 1 above as it relates to the due qualification or registration as a foreign corporation or limited liability company, as the case may be, of the Company, the Parent and the DE Subsidiaries, rely solely upon certificates of foreign qualification or registration from the Secretary of State of the applicable states, (C) with respect to the opinion expressed in paragraph 4 above with respect to the Company’s voting share, assume that such share has been duly authorized and validly issued in accordance with the LNCO LLC Agreement and is fully paid and non-assessable (D) with respect to the opinion expressed in paragraph 10 above, rely solely the Notice of Effectiveness for the Registration Statement issued on the Commission’s EDGAR System website with respect to the effectiveness thereof and, with respect to the absence of any stop orders suspending the effectiveness of the Registration Statement, rely solely upon telephonic advice of the staff of the Commission on such Delivery Date with respect to the absence of issued stop orders or proceedings.

Such counsel may state that their opinions are limited in all respects to matters of applicable provisions of United States federal law, the Delaware LLC Act and the DGCL. Such counsel may state that they do not express any opinion with respect to (i) any permits to own or operate any real or personal property, (ii) the title of any of the Company, the Parent or any of its subsidiaries to any of their respective real or personal property nor with respect to the accuracy or descriptions of real or personal property, or (iii) state or local taxes or tax statutes to which the Company, the Parent or any of its subsidiaries may be subject.

In addition, such counsel’s opinion shall state that such counsel have reviewed the Registration Statement, the Pricing Disclosure Package and the Prospectus and have participated in conferences with officers and other representatives of the Company and the Parent, with representatives of the Company’s and the Parent’s independent registered public accounting firm and the Parent’s independent petroleum engineer and with your representatives and your counsel, at which the contents of the Registration Statement, the Pricing Disclosure Package, the Prospectus and related matters were discussed. The purpose of such counsel’s professional engagement was not to establish or confirm factual matters set forth in the Registration Statement, the Pricing Disclosure Package or the Prospectus, and such counsel has not undertaken to verify independently any of the factual matters in such documents. Moreover, many of the determinations required to be made in the preparation of the Registration Statement, the Pricing Disclosure Package and the Prospectus involve matters of a non-legal nature. Accordingly, such counsel is not passing upon, and do not assume any responsibility for, the accuracy, completeness or fairness of the statements contained or included in the Registration Statement, the Pricing Disclosure Package and the Prospectus (except to the extent stated in paragraphs 9 and 11 above). Subject to the foregoing and on the basis of the information such counsel gained in the course of performing the services referred to above, such counsel advises you that:

(a) the Registration Statement, on the latest Effective Date, and the Prospectus, when filed with the Commission pursuant to Rule 424(b), appear on their face to be appropriately responsive in all material respects, to the requirements of the Securities Act and the Rules and Regulations; and

(1) the Registration Statement, as of the Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(2) the Pricing Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(3) the Prospectus, as of its date or as of the applicable Delivery Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that in each case such counsel has not been asked to, and does not, express any belief with respect to (a) the financial statements and schedules or other financial, accounting or reserve information contained or included or incorporated by reference therein or omitted therefrom, (b) the summary reserve reports of DeGolyer & MacNaughton and reserve information contained or included or incorporated by reference therein or omitted therefrom, or (c) representations and warranties and other statements of fact contained in the exhibits to the Registration Statement or to documents incorporated by reference therein.

1. All of the outstanding Units of the Parent have been duly authorized and validly issued, are fully paid (to the extent required under the Parent’s limited liability company agreement) and non-assessable (except as such non-assessability may be affected by Section 18-607, 18-303 and 18-804 of the Delaware LLC Act), conform to the description thereof contained in each of the most recent Preliminary Prospectus and the Prospectus and were issued in compliance with federal and state securities laws and not in violation of any preemptive right, resale right, right of first refusal or similar right. All of the Parent’s options, warrants and other rights to purchase or exchange any Units have been duly authorized and validly issued, conform to the description thereof contained in each of the most recent Preliminary Prospectus and the Prospectus and were issued in compliance with federal and state securities laws.

2. All of the outstanding membership interests or capital stock, as applicable, of the subsidiaries (other than Linn Exploration Midcontinent, LLC (Oklahoma), an Oklahoma limited liability company, (the “Oklahoma Company”), as to which such counsel expresses no view) have been authorized and issued in accordance with the limited liability company agreement or charter documents, as applicable, of such subsidiary, are fully paid (if a Delaware limited liability company, to the extent required under such subsidiaries’ limited liability company agreement), non-assessable (except as such non-assessability may be affected by Section 18-607, 18-303 and 18-804 of the Delaware LLC Act) and are owned directly or indirectly by the Parent only (other than with respect to the Company, of which the Parent owns all outstanding Voting Shares (as defined in the LNCO LLC Agreement)). To such counsel’s knowledge, (i) the outstanding membership interests or capital stock, as applicable, of the subsidiaries (other than the Oklahoma Company, as to which such counsel expresses no view) owned by the Parent are owned free and clear of all liens, encumbrances and claims, except for (a) contractual restrictions on transfer contained in the applicable constituent documents and the Debt Instruments and (b) liens created under or pursuant to the Bank Credit Facility and other liens permitted under the Bank Credit Facility; and (ii) no options, warrants or other rights to purchase, agreements or other obligations to issue or other rights to convert any obligations into any membership interests or capital stock of the subsidiaries (other than the Oklahoma Company, as to which such counsel expresses no view) are outstanding.

3. Such counsel knows of no material legal or governmental actions, suits or proceedings pending or threatened against the Company, the Parent or any subsidiary which would be required by the Securities Act to be disclosed in the Registration Statement except as set forth in the Pricing Disclosure Package and the Prospectus. To such counsel’s knowledge, other than as set forth in the Pricing Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending to which the Company, the Parent or its subsidiaries are a party or of which any property of the Company, the Parent or any subsidiary is the subject which are likely to result in, individually or in the aggregate, a Material Adverse Effect. Other than as set forth in the Pricing Disclosure Package and the Prospectus, to such counsel’s knowledge, no such proceedings have been overtly threatened in writing by governmental authorities or by others, which have not been resolved.

4. To such counsel’s knowledge, there are no contracts or agreements between the Company or the Parent and any person granting such person the right to require the Company or the Parent to register any securities of the Parent or the Company owned or to be owned by such person pursuant to the Registration Statement.

5. To such counsel’s knowledge, there are no agreements, contracts, indentures, leases or other instruments that are required to be described in the Registration Statement or the Disclosure Package or to be filed as an exhibit to the Registration Statement that are not described or filed as required by the Securities Act.

Such counsel may state that she expresses no opinion as to the laws of any jurisdiction other than the Included Laws. Such counsel need not make any special investigation or review of any published constitutions, treaties, laws, rules or regulations or judicial or administrative decisions (“Laws”), other than a review of (i) the Delaware General Corporation Law and the Delaware LLC Act and (ii) the federal Laws of the United States of America. For purposes of such counsel’s opinion, the term “Included Laws” means the items described in clauses (i) and (ii) of the preceding sentence that are, in such counsel’s experience, normally applicable to transactions of the type contemplated in the Pricing Disclosure Package and the Prospectus. The term “Included Laws” specifically excludes (a) Laws of any counties, cities, towns, municipalities and special political subdivisions, or foreign governments and any agencies thereof, (b) Laws relating to land use, zoning and building code issues, environmental issues, intellectual property Laws and antitrust issues, (c) tax laws, and (d) except with respect to the opinions expressed in paragraph 3, state or U.S. Federal securities Laws. Notwithstanding the foregoing, the term “Included Laws” specifically excludes laws, rules and regulations relating to the regulation of the conduct of the businesses of the Company, the Parent and its subsidiaries, including, without limitation, the laws regulating the acquisition, exploitation, exploration, development and production of oil and natural gas.

In rendering such opinion, such counsel may state that she expresses no opinion as to (i) any permits to own or operate any real or personal property, (ii) the title of the Company, the Parent or any of its subsidiaries to any of their respective real or personal property nor with respect to the accuracy or descriptions of such real or personal property, (iii) state or local taxes or tax statutes to which the Company, the Parent or any of its subsidiaries may be subject, (iv) the financial condition or solvency of the Company, the Parent or any of its subsidiaries, or (v) the ability (financial or otherwise) of Company, the Parent or any of its subsidiaries or any other party to meet its obligations under the Transaction Documents.

This letter is being delivered to you in connection with the offering by [LinnCo, LLC] ][Linn Energy, LLC] (the “Company”) of [—] [Common Shares][Units], $[—] par value (the “[Common Shares][Units]”), of the Company and the lock-up letter agreement dated [insert date] (the “Lock-Up Agreement”), executed by you in connection with such offering, and your request for a [waiver] [release] dated [insert date] with respect to [—][Common Shares][Units] (the “[Shares][Units]”).
