Ladies and Gentlemen:

     Linn Energy, LLC, a Delaware limited liability company (the “Company”), and Linn Energy Finance Corp., a Delaware corporation (together with the Company, the “Issuers,” and each of them, an “Issuer”), propose to sell an aggregate of $750,000,000 principal amount of the Company’s and Linn Energy Finance Corp.’s 6.500% Senior Notes due 2019 (the “Notes”) to the initial purchasers (the “Initial Purchasers”) named in Schedule 1 attached to this agreement (this “Agreement”), for whom you are acting as the representatives (the “Representatives”). The Notes will be issued pursuant to an Indenture (the “Indenture”) to be dated as of the Closing Date (as defined in Section 3(a)), among the Issuers, the Guarantors (as defined below) and U.S. Bank National Association, as trustee. The Notes will be issued only in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “DTC”) pursuant to a blanket letter of representations dated June 26, 2008 (the “DTC Agreement”) from the Issuers.

     The holders of the Notes will be entitled to the benefits of a registration rights agreement, to be dated as of the Closing Date (the “Registration Rights Agreement”), among the Issuers, the Guarantors and the Initial Purchasers, pursuant to which the Issuers and the Guarantors will agree to file with the Securities and Exchange Commission (the “Commission”) (i) a registration statement under the Securities Act of 1933, as amended (the “Securities Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder)

relating to another series of debt securities of the Issuers and the guarantees of the Guarantors under the Indenture, each respectively with terms substantially identical to the Notes (the “Exchange Notes”) and the Guarantees (the “Exchange Guarantees”) to be offered in exchange for the Notes and the Guarantees (the “Exchange Offer”) and (ii) to the extent required by the Registration Rights Agreement, a shelf registration statement pursuant to Rule 415 of the Securities Act relating to the resale by certain holders of the Notes, and in each case, to use its reasonable best efforts to cause such registration statements to be declared effective.

     The payment of principal of, premium and Additional Interest (as defined in the Indenture), if any, and interest on the Notes and the Exchange Notes will be fully and unconditionally guaranteed on a senior unsecured basis, jointly and severally, by (i) the guarantors listed on Schedule 2 attached hereto and (ii) any subsidiary of the Company formed or acquired after the Closing Date that executes an additional guarantee in accordance with the terms of the Indenture, and their respective successors and assigns (such persons referred to in clauses (i) and (ii) are collectively referred to as the “Guarantors”), pursuant to their guarantees (the “Guarantees”). The Notes and the Guarantees are herein collectively referred to as the “Securities,” and the Exchange Notes and the Exchange Guarantees are herein collectively referred to as the “Exchange Securities.”

     The Issuers and the Guarantors understand that the Initial Purchasers propose to make an offering of the Securities on the terms and in the manner set forth herein and in the Pricing Disclosure Package (as defined below) and agree that the Initial Purchasers may resell, subject to the conditions set forth herein, all or a portion of the Securities to purchasers (the “Subsequent Purchasers”) on the terms set forth in the Pricing Disclosure Package (the first time when sales of the Securities are made by the Initial Purchasers is referred to herein as the “Time of Sale”). The Securities are to be offered and sold to or through the Initial Purchasers without being registered with the Commission under the Securities Act, in reliance upon exemptions therefrom. Pursuant to the terms of the Securities and the Indenture, investors who acquire Securities shall be deemed to have agreed that Securities may only be resold or otherwise transferred, after the date hereof, if such Securities are registered for sale under the Securities Act or if an exemption from the registration requirements of the Securities Act is available (including the exemptions afforded by Rule 144A under the Securities Act (“Rule 144A”) and Regulation S under the Securities Act (“Regulation S”)).

     In connection with the sale of the Securities, the Company has prepared and delivered to each Initial Purchaser copies of a Preliminary Offering Memorandum dated May 9, 2011 (the “Preliminary Offering Memorandum”), and has prepared and delivered to each Initial Purchaser copies of a Pricing Supplement dated May 10, 2011, substantially in the form of Exhibit A (the “Pricing Supplement”), describing the terms of the Securities, each for use by the Initial Purchasers in connection with its solicitation of offers to purchase the Securities. The Preliminary Offering Memorandum, as supplemented by the Pricing Supplement, is herein referred to as the “Pricing Disclosure Package.” Promptly after this Agreement is executed and delivered, and in any event not later than the second business day following the date hereof, the Company will prepare and deliver to each Initial Purchaser a final offering memorandum, dated as of the date hereof (the “Offering Memorandum”).

     All references herein to the terms “Pricing Disclosure Package” and “Offering Memorandum” shall be deemed to mean and include all information filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act,” which term, as used herein, includes the rules and regulations of the Commission promulgated thereunder), prior to the Time of Sale and incorporated by reference in the Pricing Disclosure Package (including the Preliminary Offering Memorandum) or the Offering Memorandum (as the case may be), and all references herein to the terms “amend,” “amendment” or “supplement” with respect to the Offering Memorandum shall be deemed to mean and include all information filed under the Exchange Act after the Time of Sale and incorporated by reference in the Offering Memorandum.

     (k) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in securities generally on the New York Stock Exchange, the NYSE Amex Equities, the Nasdaq Stock Market or in the over-the-counter market shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on any such exchange or such market by the Commission, by such exchange or by any other regulatory body or governmental authority having jurisdiction, (ii) trading in any securities of the Company on any exchange or in the over-the-counter market shall have been suspended or materially limited, (iii) a banking moratorium shall have been declared by federal or state authorities, (iv) the United States shall have become engaged in hostilities, there shall have been an escalation in hostilities involving the United States or there shall have been a declaration of a national emergency or war by the United States or (v) there shall have occurred such a material adverse change in general economic, political or financial conditions, including, without limitation, as a result of terrorist activities after the date hereof (or the effect of international conditions on the financial markets in the United States shall be such), as to make it, in the judgment of the Representatives, impracticable or inadvisable to proceed with the offering or delivery of the Notes being delivered on such Closing Date on the terms and in the manner contemplated in the Offering Memorandum.

     (l) The Issuers and the Guarantors shall have entered into the Registration Rights Agreement and the Initial Purchasers or their counsel shall have received executed counterparts thereof.

     (m) The Issuers, the Guarantors and the Trustee shall have executed and delivered the Indenture, and the Initial Purchasers or their counsel shall have received an executed counterpart thereof, duly executed by the Issuers, the Guarantors and the Trustee.

     (n) The Issuers and the Guarantors shall have furnished the Representatives and counsel to the Initial Purchasers with such other certificates, opinions or other documents as they may have reasonably requested.

          All opinions, letters, evidence and certificates mentioned above or elsewhere in this Agreement shall be deemed to be in compliance with the provisions hereof only if they are in all material respects reasonably satisfactory to counsel for the Initial Purchasers.

          8. Indemnification and Contribution.

     (a) Each of the Issuers and the Guarantors, jointly and severally, shall indemnify and hold harmless each Initial Purchaser, its directors, officers, employees, each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the Securities Act, each affiliate of any Initial Purchaser within the meaning of Rule 405 under the Securities Act and each agent of any Initial Purchaser from and against any 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 Notes and Guarantees), to which that Initial Purchaser, director, officer, employee, controlling person, affiliate or any agent of any Initial Purchaser 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 the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto, any materials or information provided to investors by, or with the approval of, the Issuers or any Guarantor in connection with the marketing of the offering of the Notes (“Marketing Materials”), including any road show or investor presentations made to investors by the Issuers (whether in person or electronically) or any Blue Sky application or other document prepared or executed by the Issuers (or based upon any written information furnished by the Issuers for use therein) specifically for the purpose of qualifying any or all of the Notes 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 the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, and shall reimburse each Initial Purchaser and each such director, officer, employee, controlling person, affiliate or any agent of any Initial Purchaser promptly upon demand for any legal or other out-of-pocket expenses reasonably incurred by that Initial Purchaser, director, officer, employee, controlling person, affiliate or any agent of any Initial Purchaser 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 Issuers and the Guarantors 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 the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto, any Marketing Materials or any Blue Sky Application, in reliance upon and in conformity with written information furnished to the Issuers through the Representatives by or on behalf of any

Initial Purchaser 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 Issuers or the Guarantors may otherwise have to any Initial Purchaser or to any director, officer, employee, controlling person, affiliate or any agent of that Initial Purchaser.

     (b) Each Initial Purchaser, severally and not jointly, shall indemnify and hold harmless each Issuer, each of the Guarantors and their respective directors, officers and employees, and each person, if any, who controls the Issuers or the Guarantors, as the case may be, within the meaning of Section 15 of the Securities Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which the Issuers, the Guarantors or any such directors, officers, employees 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 the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto, any Marketing Materials or any Blue Sky Application, or (ii) the omission or alleged omission to state in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto, any Marketing Materials or any Blue Sky Application, any material fact required to be stated therein or necessary in order to make the statements therein, 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 furnished to the Issuers through the Representatives by or on behalf of that Initial Purchaser 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 Initial Purchaser may otherwise have to the Issuers, any Guarantor and 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 Section 8(a) or (b), 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 Section 8(a) or (b) except to the extent it has been materially prejudiced 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 Section 8(a) or (b). 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 and controlling persons 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 and controlling persons 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 or controlling persons, 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 (i) 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 any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) 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 Issuers and the Guarantors, on the one hand, and the Initial Purchasers, on the other, from the offering of the Notes and Guarantees 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 Issuers and the Guarantors, on the one hand, and the Initial Purchasers, 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 Issuers and the Guarantors, on the one hand, and the Initial Purchasers, 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 Notes purchased under this Agreement (before deducting expenses) received by the Issuers and the Guarantors, on the one hand, and the total purchase discounts and commissions received by the Initial Purchasers with respect to the Notes purchased under this Agreement, on the other hand, bears to the total gross proceeds from the offering of the Notes under this Agreement. 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 Issuers, the Guarantors or the Initial Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. For purposes of the preceding two sentences, the net proceeds deemed to be received by the Issuers shall be deemed to be also for the benefit of the Guarantors, and information supplied by the Issuers shall also be deemed to have been supplied by the Guarantors. The Issuers, the Guarantors and the Initial Purchasers 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 Initial Purchasers 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), no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale of the Notes purchased by it exceeds the amount of any damages that such Initial Purchaser has otherwise paid or become liable to pay by reason of any 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 Initial Purchasers’ obligations to contribute as provided in this Section 8(d) are several in proportion to their respective purchase obligations and not joint.

     (e) The Initial Purchasers severally confirm and the Issuers and the Guarantors acknowledge and agree that the statement regarding delivery of Notes by the Initial Purchasers set forth on the cover page of, and the third, ninth and tenth paragraphs appearing under the caption “Plan of Distribution” in, the Pricing Disclosure Package and the Offering Memorandum are correct and constitute the only information concerning such Initial Purchasers furnished in writing to any Issuer or any Guarantor by or on behalf of the Initial Purchasers specifically for inclusion in the Preliminary Offering Memorandum, the Pricing Supplement, any Additional Written Communication, the Offering Memorandum or in any amendment or supplement thereto.

          9. Defaulting Initial Purchasers. If, on the Closing Date, any Initial Purchaser defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Initial Purchasers shall be obligated to purchase the Securities that the defaulting

Initial Purchaser agreed but failed to purchase on the Closing Date in the respective proportions which the principal amount of the Securities set forth opposite the name of each remaining non-defaulting Initial Purchaser in Schedule 1 hereto bears to the total principal amount of the Securities set forth opposite the names of all the remaining non-defaulting Initial Purchasers in Schedule 1 hereto; provided, however, that the remaining non-defaulting Initial Purchasers shall not be obligated to purchase any of the Securities on the Closing Date if the total principal amount of the Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on such date exceeds 10.0% of the total principal amount of the Securities to be purchased on the Closing Date, and any remaining non-defaulting Initial Purchaser shall not be obligated to purchase more than 110.0% of the principal amount of the Securities that it agreed to purchase on the Closing Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Initial Purchasers, or those other initial purchasers satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, all the Securities to be purchased on the Closing Date. If the remaining Initial Purchasers or other initial purchasers satisfactory to the Representatives do not elect to purchase the Securities that the defaulting Initial Purchaser or Initial Purchasers agreed but failed to purchase on the Closing Date, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser, the Issuers or the Guarantors, except that the Issuers and Guarantors will continue to be liable for the payment of expenses to the extent set forth in Section 6. As used in this Agreement, the term “Initial Purchaser” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule 1 hereto that, pursuant to this Section 9, purchases Securities that a defaulting Initial Purchaser agreed but failed to purchase.

          Nothing contained herein shall relieve a defaulting Initial Purchaser of any liability it may have to the Issuers or Guarantors for damages caused by its default. If other Initial Purchasers are obligated or agree to purchase the Securities of a defaulting or withdrawing Initial Purchaser, either the Representatives or the Company may postpone the Closing 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 Initial Purchasers may be necessary in the Pricing Disclosure Package or the Offering Memorandum or in any other document or arrangement.

          10. Termination. The obligations of the Initial Purchasers hereunder may be terminated by the Representatives by notice given to and received by the Company prior to delivery of and payment for the Securities if, prior to that time, any of the events described in Sections 7(i), 7(j) and 7(k) shall have occurred or if the Initial Purchasers shall decline to purchase the Securities for any reason permitted under this Agreement.

          11. Reimbursement of Initial Purchasers’ Expenses. If the Issuers shall fail to tender the Securities for delivery to the Initial Purchasers (i) by reason of any failure, refusal or inability of the Issuers or the Guarantors to perform any agreement on their respective parts to be performed, (ii) because any other condition to the Initial Purchasers’ obligations hereunder required to be fulfilled by any of the Issuers or the Guarantors is not fulfilled for any reason or (iii) because the Initial Purchasers shall decline to purchase the Securities for any reason permitted under this Agreement, the Issuers will reimburse the Initial Purchasers for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) reasonably incurred by the Initial Purchasers in connection with this Agreement and the

proposed purchase of the Securities, and upon demand the Issuers shall pay the full amount thereof to the Representatives; provided, however, that if this Agreement is terminated pursuant to Section 7(k) (other than due to Section 7(k)(ii)) or pursuant to Section 9 by reason of the default of one or more Initial Purchasers, the Issuers shall not be obligated to reimburse any Initial Purchaser on account of those expenses.

          12. Offer, Sale and Resale Procedures. Each of the Initial Purchasers, on the one hand, and each of the Issuers and the Guarantors, on the other hand, hereby agrees that it has observed and will observe the following procedures in connection with the offer and sale of the Securities:

     (a) Offers and sales of the Securities will be made only by the Initial Purchasers or affiliates thereof qualified to do so in the jurisdictions in which such offers or sales are made. Each such offer or sale shall only be made to persons whom the offeror or seller reasonably believes to be Qualified Institutional Buyers or non-U.S. persons outside the United States to whom the offeror or seller reasonably believes offers and sales of the Securities may be made in reliance upon Regulation S upon the terms and conditions set forth in Schedule 4 attached hereto, which Schedule 4 is hereby expressly made a part hereof.

     (b) The Securities will be offered by approaching prospective Subsequent Purchasers on an individual basis. No general solicitation or general advertising (within the meaning of Rule 502 under the Securities Act) will be used in the United States in connection with the offering of the Securities.

     (c) Upon original issuance by the Company, and until such time as the same is no longer required under the applicable requirements of the Securities Act, the Notes (and all securities issued in exchange therefor or in substitution thereof, other than the Exchange Notes) shall bear the legend specified in the Indenture. Following the sale of the Securities by the Initial Purchasers to Subsequent Purchasers pursuant to the terms hereof, the Initial Purchasers shall not be liable or responsible to the Company for any losses, damages or liabilities suffered or incurred by the Company, including any losses, damages or liabilities under the Securities Act, arising from or relating to any resale or transfer of any Security.

          13. Research Analyst Independence. The Issuers and the Guarantors acknowledge that the Initial Purchasers’ 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 Initial Purchasers’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Issuers, the Guarantors and/or the offering that differ from the views of their respective investment banking divisions. The Issuers and the Guarantors hereby waive and release, to the fullest extent permitted by law, any claims that any Issuer or any of the Guarantors may have against the Initial Purchasers 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 Issuers or the Guarantors by such Initial Purchasers’ investment banking divisions. The Issuers

and the Guarantors acknowledge that each of the Initial Purchasers 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 Company.

          14. No Fiduciary Duty. The Issuers and the Guarantors hereby acknowledge that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Issuers and the Guarantors, on the one hand, and the Initial Purchasers and any Affiliate through which they may be acting, on the other, (b) the Initial Purchasers are acting as principal and not as an agent or fiduciary of the Issuers or the Guarantors and (c) the Issuers and the Guarantors’ engagement of the Initial Purchasers in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Issuers and the Guarantors agree that they are solely responsible for making their own judgments in connection with the offering (irrespective of whether any of the Initial Purchasers has advised or is currently advising the Issuers or the Guarantors on related or other matters). The Issuers and the Guarantors agree that they will not claim that the Initial Purchasers have rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Issuers or the Guarantors, in connection with such transaction or the process leading thereto.

          15. Notices, Etc. All statements, requests, notices and agreements hereunder shall be in writing, and:

     (a) if to the Initial Purchasers, shall be delivered or sent by mail or facsimile transmission to: Citigroup Global Markets Inc., 388 Greenwich Street, New York, New York, Attention: General Counsel, Fax: 212 ###-###-####; and

     (b) if to the Issuers, shall be delivered or sent by mail or facsimile transmission to Linn Energy, LLC, 600 Travis Street, Suite 5100, Houston, Texas 77002, Attention: General Counsel, Fax: 281 ###-###-####.

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof. The Issuers shall be entitled to act and rely upon any request, consent, notice or agreement given or made on behalf of the Initial Purchasers by the Representatives.

          16. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Initial Purchasers, the Issuers, the Guarantors and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except that (a) the representations, warranties, indemnities and agreements of the Issuers and the Guarantors contained in this Agreement shall also be deemed to be for the benefit of the directors, officers and employees of the Initial Purchasers and each person or persons, if any, who control any Initial Purchaser within the meaning of Section 15 of the Securities Act and (b) the indemnity agreement of the Initial Purchasers contained in Section 8(b) of this Agreement shall be deemed to be for the benefit of the directors of the Issuers and the Guarantors and any person controlling the Issuers or the Guarantors within the meaning of Section 15 of the Securities Act. Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 16, any legal or

equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

          17. Survival. The respective indemnities, representations, warranties and agreements of the Issuers, the Guarantors and the Initial Purchasers contained in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall survive the delivery of and payment for the Notes and shall remain in full force and effect, regardless of any investigation made by or on behalf of any of them or any person controlling any of them.

          18. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means each Monday, Tuesday, Wednesday, Thursday or Friday that is not a day on which banking institutions in New York are generally authorized or obligated by law or executive order to close and (b) “subsidiary” has the meaning set forth in Rule 405 of the Securities Act.

          19. Partial Enforceability. The invalidity or unenforceability of any section, paragraph or provision of this Agreement shall not affect the validity or enforceability of any other section, paragraph or provision hereof. If any section, paragraph or provision of this Agreement is, for any reason, determined to be invalid or unenforceable, there shall be deemed to be made such minor changes (and only such minor changes) as are necessary to make it valid and enforceable and to effect the original intent of the parties hereto.

          20. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to the conflicts of law rules thereof.

          21. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

          22. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

          23. Amendments; Waivers. This Agreement may only be amended or modified in writing, signed by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit.

SCHEDULE 4

     Resale Pursuant to Regulation S or Rule 144A. Each Initial Purchaser understands that:

     Such Initial Purchaser agrees that it has not offered or sold and will not offer or sell the Securities in the United States or to, or for the benefit or account of, a U.S. Person (other than a distributor), in each case, as defined in Rule 902 of Regulation S (i) as part of its distribution at any time and (ii) otherwise until 40 days after the later of the commencement of the offering of the Securities pursuant hereto and the Closing Date, other than in accordance with Regulation S or another exemption from the registration requirements of the Securities Act.

The Transaction Documents (other than the Exchange Securities) have been duly and validly executed and delivered by each of the Issuers and the Delaware Guarantors that is a party thereto.

     4. The Securities, when authenticated in accordance with the provisions of the Indenture and delivered to and paid for by the Initial Purchasers in accordance with the terms of this Agreement, will be valid and legally binding obligations of the Issuers, entitled to the benefits of the Indenture and enforceable against the Issuers in accordance with their respective terms. The Exchange Securities, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will constitute valid and legally binding obligations of the Issuers, enforceable against the Issuers in accordance with their respective terms.

     5. The Indenture (including, with respect to the Guarantors, when the Securities have been duly and validly authenticated in accordance with the terms of the Indenture and duly and validly paid for by and delivered to the Initial Purchasers in accordance with the terms of this Agreement, the guarantee of the Guarantors provided for in Article X thereof) constitutes the

     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 the Transaction Documents by the Issuers and the Guarantors party thereto and the performance by the Issuers and the Guarantors of their respective obligations under the Transaction Documents to which they are a party, subject to the assumptions set forth in paragraph 13 and except for (i) routine Filings necessary in connection with the conduct of the business of the Issuers and the Guarantors, including routine Filings required to be made under the Exchange Act, (ii) such other Filings as have been obtained or made, (iii) such Filings required under the Securities Act or the Exchange Act as provided in this Agreement, (iv) Filings required under Federal and state securities laws as provided in the Registration Rights Agreement, and (v) Filings required to maintain corporate and similar standing and existence.

     9. The statements in the Preliminary Offering Memorandum and the Offering Memorandum under the caption “Description of Notes” and “Description of Existing Indebtedness” insofar as such statements purport to summarize certain provisions of documents referred to therein and reviewed by us as described above, fairly summarize such provisions in all material respects, subject to the qualifications and assumptions stated therein. The statements in the Preliminary Offering Memorandum and the Offering Memorandum under the caption “Description of Notes” and “Description of Existing Indebtedness” insofar as such statements purport to summarize provisions of any law, statute, rule or regulation of or under any Included Law referred to therein, fairly summarize such laws, statutes, rules and regulations in all material respects, subject to the qualifications and assumptions stated therein. The Indenture and the Securities conform, and the Exchange Securities, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will conform, in all material respects as to legal matters to the descriptions thereof under the heading “Description

of Notes” in the Pricing Disclosure Package and the Offering Memorandum (in the case of the Pricing Disclosure Package, when considered together with the Pricing Supplement).

     10. The statements in the Preliminary Offering Memorandum and the Offering Memorandum under the caption “Certain U.S. Federal Income and Estate Tax Considerations,” insofar as such statements constitute a summary of the United States federal tax laws referred to therein, as of the date of the Preliminary Offering Memorandum and the Offering Memorandum, in all material respects, are accurate and fairly summarize the United States federal tax laws referred to therein, subject to the qualifications and assumptions stated therein.

     11. The documents filed under the Exchange Act and incorporated by reference in the Pricing Disclosure Package and the Offering Memorandum or any amendment thereof or supplement thereto (other than the financial statements, including the notes thereto, and any other financial, pro forma financial, accounting and statistical data and reserve information included or incorporated by reference therein, as to which no opinion is rendered, and in the case of any such incorporated document that was subsequently amended, such document as amended by the subsequently filed amendment) when they were filed (after giving effect to subsequent amendments, if applicable) with the Commission, appear on their face to be appropriately responsive in all material respects to the requirements of the Exchange Act and the applicable rules and regulations thereunder.

     12. The Issuers and the Guarantors are not, and after giving effect to the offering and sale of the Securities contemplated by this Agreement and the application of the net proceeds from such sale as described in the Preliminary Offering Memorandum and the Offering Memorandum, the Issuers and the Guarantors will not be required to register as an “investment company,” as such term is defined under the 1940 Act.

     13. Assuming without independent investigation, (a) that the Securities are sold to the Initial Purchasers, and initially resold by the Initial Purchasers, in accordance with the terms of and in the manner contemplated by, this Agreement and the Offering Memorandum; (b) the accuracy of the representations and warranties of the Issuers and the Guarantors set forth in this Agreement and in those certain certificates delivered on the date hereof; (c) the accuracy of the representations and warranties of the Initial Purchasers set forth in this Agreement; (d) the due performance and compliance by the Issuers, the Guarantors and the Initial Purchasers of their respective covenants and agreements set forth in this Agreement; and (e) the Initial Purchasers’ compliance with the Offering Memorandum and the transfer procedures and restrictions described therein, it is not necessary to register the Securities under the Securities Act or to qualify an indenture in respect thereof under the Trust Indenture Act (the “TIA”) in connection with the issuance and sale of the Securities by the Issuers to the Initial Purchasers or in connection with the offer, resale and delivery of the Securities by the Initial Purchasers in the manner contemplated by this Agreement and the Offering Memorandum, it being expressly understood that we express no opinion in this paragraph 13 or paragraph 8 as to any subsequent offer or resale of any of the Securities.

     14. The execution and delivery of the Transaction Documents by the Issuers and the Guarantors party thereto do not, and the performance by the Issuers and the Guarantors of their obligations thereunder will not, result in any violation of any order, writ, judgment or decree

under any Included Law which is applicable to the Issuers or any Guarantor or their assets or properties.

     15. The Indenture conforms in all material respects to the requirements of the TIA and the rules and regulations of the Commission applicable to an indenture which is qualified thereunder.

     16. The Third Amended and Restated Limited Liability Company Agreement of the Company dated as of September 3, 2010 has been duly authorized, executed and delivered by the Company and is a valid and legally binding agreement of the Company, enforceable against the Company 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) rely in respect of matters of fact upon certificates of officers and employees of the Company and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (C) state that their opinion is limited to federal laws, the laws of the State of New York, the Delaware LLC Act and the DGCL, (D) with respect to the opinions expressed in paragraph 1 above as to the due qualification or registration as a foreign corporation or limited liability company, as the case may be, of the Issuers and the Delaware Guarantors state that such opinions are based upon certificates of foreign qualification or registration provided by the Secretary of State of the applicable states (each of which will be dated not more than five days prior to such Closing Date, as the case may be, and shall be provided to the Representatives), (E) state that they express no opinion with respect to any permits to own or operate any real or personal property, (F) state that they express no opinion with respect to the title of any of the Company 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, (G) state that they express no opinion with respect to state or local taxes or tax statutes to which the Company or any of its Subsidiaries may be subject and (H) state that they express no opinion as to the financial statements, including the notes thereto, and any other financial, pro forma financial, accounting data and reserve information contained or incorporated by reference in the Pricing Disclosure Package or the Offering Memorandum.

     In addition, such counsel shall also have furnished to the Initial Purchasers a written statement addressed to the Initial Purchasers and dated as of the Closing Date, in form and substance satisfactory to the Initial Purchasers, to the effect that such counsel has reviewed each of the Offering Memorandum and the Pricing Disclosure Package and have participated in conferences with officers and other representatives of the Issuers, with representatives of the Issuers’ independent registered public accounting firm and independent petroleum engineer, representatives of the Initial Purchasers and representatives of the Initial Purchasers’ counsel, at which the contents of the Offering Memorandum and the Pricing Disclosure Package 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 Offering Memorandum and the Pricing Disclosure Package, 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 Offering Memorandum and the Pricing Disclosure Package involve matters of a non-legal nature. Accordingly, such counsel is not passing upon and does not assume any responsibility for the accuracy, completeness or fairness of the statements included in the Offering Memorandum and the Pricing Disclosure Package (except to the extent stated in paragraphs 9 and 10 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 that nothing came to their attention that caused them to believe that:

	(A)		the Offering Memorandum, as of its date or as of the Closing 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 or
	(B)		the Pricing Disclosure Package, as of the Time of Sale (which you have informed us is a time after the Pricing Supplement specified on Annex A hereto was made available to investors), 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 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 (i) the financial statements and schedules or other financial, accounting or reserve information contained or included or incorporated by reference therein, or omitted therefrom, (ii) the summary reserve report of DeGolyer and MacNaughton and reserve information included or incorporated by reference therein, or omitted therefrom, or (iii) representations and warranties and other statements of fact contained in the exhibits to the documents incorporated by reference therein.
