          1. Description of Units. The Company proposes to issue and sell through or to the Manager, as sales agent and/or principal, units representing limited liability company interests in the Company (the “Units”), having an aggregate gross sales price of up to $500,000,000 (the “Offered Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. For purposes of selling the Offered Units through the Manager, the Company hereby appoints the Manager as exclusive agent of the Company for the purpose of soliciting purchases of the Offered Units from the Company pursuant to this Agreement and the Manager agrees to use its reasonable efforts to solicit purchases of the Offered Units on the terms and subject to the conditions stated herein. The Company agrees that whenever it determines to sell the Offered Units directly to the Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”) in substantially the form of Annex I hereto, relating to such sale in accordance with Section 3 of this Agreement. Certain terms used herein are defined in Section 18 hereof.

          2. Representations and Warranties. The Company represents and warrants to, and agrees with, the Manager at the Execution Time and on each such time that the following representations and warranties are affirmed or deemed to be made pursuant to this Agreement, as set forth below.

Such Registration Statement, including any amendments thereto filed prior to the Execution Time or prior to any such time this representation is repeated or deemed to be made, became effective upon filing. The Company has filed with the Commission the Prospectus Supplement relating to the

          3. Sale and Delivery of Offered Units.

          (a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Company agrees to issue and sell Offered Units from time to time through the Manager, acting as sales agent, and the Manager agrees to

use its reasonable efforts to sell, as sales agent for the Company, the Offered Units on the following terms.

     (i) The Offered Units are to be sold on a daily basis or otherwise as shall be agreed to by the Company and the Manager on any day that (A) is a trading day for the Nasdaq (other than a day on which the Nasdaq is scheduled to close prior to its regular weekday closing time), (B) the Company, through any of the individuals listed as Authorized Representatives on Schedule III hereto, has instructed the Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Company has satisfied its obligations under Section 6 of this Agreement. The Company will designate the maximum amount of the Offered Units to be sold by the Manager daily as agreed to by the Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Unit at which such Offered Units may be sold. Subject to the terms and conditions hereof, the Manager shall use its reasonable efforts to sell on a particular day all of the Offered Units designated for sale by the Company on such day. The gross sales price of the Offered Units sold under this Section 3(a) shall be the market price for the Units sold by the Manager under this Section 3(a) on the Nasdaq at the time of sale of such Offered Units.

     (ii) The Company acknowledges and agrees that (A) there can be no assurance that the Manager will be successful in selling the Offered Units, (B) the Manager will incur no liability or obligation to the Company or any other person or entity if it does not sell Offered Units for any reason other than a failure by the Manager to use its reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Offered Units as required under this Agreement, and (C) the Manager shall be under no obligation to purchase Offered Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by the Manager and the Company in writing pursuant to a Terms Agreement.

     (iii) The Company shall not authorize the issuance and sale of, and the Manager shall not be obligated to use its reasonable efforts to sell, any Offered Units at a price lower than the minimum price therefor designated from time to time by the Company’s Board of Directors (the “Board”), or a duly authorized committee thereof, and notified to the Manager in writing. The Company or the Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend the offering of the Offered Units for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Offered Units sold hereunder prior to the giving of such notice.

     (iv) The Manager hereby covenants and agrees not to make any sales of the Offered Units on behalf of the Company, pursuant to this Section 3(a), other than (A) by means of ordinary brokers’ transactions between members of the Nasdaq that qualify for delivery of a Prospectus to the Nasdaq in accordance

with Rule 153 (such transactions are hereinafter referred to as “Continuous Offerings”) and (B) such other sales of the Offered Units on behalf of the Company in its capacity as agent of the Company as shall be agreed by the Company and the Manager pursuant to a Terms Agreement.

     (v) The compensation to the Manager for sales of the Offered Units with respect to which the Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Offered Units sold pursuant to this Section 3(a) and payable as described below. The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Company may sell Offered Units to the Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The gross proceeds less the Manager’s commission, shall constitute the net proceeds to the Company for such Offered Units (the “Net Proceeds”). Payment of the Net Proceeds after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”), for Offered Units sold by the Company on any Settlement Date shall be made to the Company by federal funds wire transfer to the account of the Company against delivery of such Offered Units to the Manager’s account, or an account of Manager’s designee, at The Depository Trust Company.

     (vi) The Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Company following the close of trading on the Nasdaq each day in which the Offered Units are sold under this Section 3(a) setting forth the number of the Offered Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Company, and the compensation payable by the Company to the Manager with respect to such sales.

     (vii) Settlement for sales of the Offered Units pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Offered Units sold through the Manager for settlement on such date shall be issued and delivered by the Company to the Manager against payment of the Net Proceeds for the sale of such Offered Units. Settlement for all such Offered Units shall be effected by free delivery of the Offered Units to the Manager’s account at The Depository Trust Company (“DTC”) in return for payments in same day funds delivered to the account designated by the Company. If the Company or its transfer agent (if applicable) shall default on its obligation to deliver the Offered Units on any Settlement Date, the Company shall (A) indemnify and hold the Manager harmless against any loss, claim or damage arising from or as a result of such default by the Company and (B) pay the Manager any commission to which it would otherwise be entitled absent such default. If the Manager breaches this Agreement by failing to deliver the Net Proceeds less any Transaction Fees to the Company on any Settlement Date for the Offered Units delivered by the Company, the Manager will pay the Company interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to the Manager.

     (viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), the Company shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, modified as necessary to relate to the Registration Statement and the Prospectus as amended as of such date and to reflect such necessary modifications as are not material and approved by the Manager in advance. Any obligation of the Manager to use its reasonable efforts to sell the Offered Units on behalf of the Company shall be subject to the continuing accuracy of the representations and warranties of the Company herein, to the performance by the Company of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

          (b) If the Company wishes to issue and sell the Offered Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Manager of the proposed terms of such Placement. If the Manager, acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Company wishes to accept amended terms, the Manager and the Company will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Company or the Manager unless and until the Company and the Manager have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

          (c) Each sale of the Offered Units to the Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Offered Units to, and the purchase thereof by, the Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Units by the Manager. The commitment of the Manager to purchase the Offered Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Offered Units to be purchased by the Manager pursuant thereto, the price to be paid to the Company for such Offered Units, any provisions relating to rights of, and default by, underwriters acting together with the Manager in the reoffering of the Offered Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Offered Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters, reserve engineer’s letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by the Manager.

          (d) Under no circumstances shall the number and aggregate amount of the Offered Units sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Offered Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Manager in writing.

          (e) If either party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Offered Units, it shall promptly notify the other party and sales of the Offered Units under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

          4. Agreements. The Company agrees with the Manager that:

          (a) During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Securities Act, prior to filing any amendment of the Registration Statement or supplement (including the Prospectus Supplement) to the Base Prospectus, the Company will furnish to the Manager for review a copy of each such proposed amendment or supplement, and the Company shall not use any such proposed amendment or supplement to which the Manager reasonably objects (for the avoidance of doubt, this provision shall not apply to any periodic or current report required to be filed by the Company under the Exchange Act with respect to matters unrelated to the Offered Units). The Company has properly completed the Prospectus, in a form approved by the Manager, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Manager of such timely filing. The Company will promptly advise the Manager (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, during any period when the delivery of a prospectus (whether physically or through compliance with Rule 172 or any similar rule) is required under the Securities Act in connection with the offering or sale of the Offered Units, any amendment to the Registration Statement shall have been filed or become effective, (iii) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Offered Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Company will use its reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement and using its reasonable best efforts to have such amendment declared effective as soon as practicable.

          (b) If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Company will (i) notify promptly

the Manager so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Manager in such quantities as the Manager may reasonably request.

          (c) During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Securities Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement or supplement the Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Company promptly will (i) notify the Manager of any such event, (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Manager in such quantities as the Manager may reasonably request.

          (d) As soon as practicable, the Company will make generally available to its security holders and to the Manager an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Securities Act and Rule 158.

          (e) The Company will furnish to the Manager and counsel for the Manager, without charge, as many copies of the Registration Statement (including exhibits thereto), the Prospectus and each Issuer Free Writing Prospectus and any supplement thereto and any documents incorporated by reference therein as the Manager may reasonably request.

          (f) The Company will arrange, if necessary, for the qualification (or will obtain exemptions from qualification) of the Offered Units for sale under the laws of such jurisdictions as the Manager may designate and will maintain such qualifications in effect so long as required for the distribution of the Offered Units; provided that in no event shall the Company be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to general service of process in any jurisdiction, other than service of process arising out of the offering or sale of the Offered Units, where it is not now so subject or where it would be subject to taxation as a foreign limited liability company.

          (g) The Company agrees that, unless it has or shall have obtained the prior written consent of the Manager, and the Manager agrees with the Company that, unless it has or shall have obtained, as the case may be, the prior written consent of the Company, it has not made and will not make any offer relating to the Offered Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company with the Commission or retained by the Company under Rule 433; provided that the prior written consent of the parties hereto shall

be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto. Any such free writing prospectus consented to by the Manager or the Company is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Company agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

          (h) The Company will not (A) issue, offer, sell, agree to issue, offer or sell, solicit offers to purchase, pledge or otherwise dispose of (or enter into any transaction or duties which is designed to, or could be expected to, result in the disposition by any person at any time in the future) any Units or securities convertible into or exchangeable for Units, or sell or grant options, rights or warrants with respect to any Units or securities convertible into or exchangeable for Units, (B) 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 such Units, (C) file or cause to be filed a registration statement, including any amendments, with respect to the registration of any Units or securities convertible, exercisable or exchangeable into Units or any other securities of the Company or (D) publicly disclose the intention to do any of the foregoing without (i) giving the Manager at least five Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction and (ii) the Manager suspending acting under this Agreement for such period of time requested by the Company or as deemed appropriate by the Manager in light of the proposed transaction; provided, however, that this provision will not apply to the sale of Units pursuant to this Agreement or any Terms Agreement, to the vesting of restricted Units or net exercises of options to purchase Units and withholding of Units to pay income taxes upon the vesting of restricted Units under the Company’s long-term incentive plan in effect at the Execution Time, or to the Company’s awarding restricted units and options to purchase its Units or issuing Units upon the exercise of Unit options pursuant to the Company’s long-term incentive plan in effect at the Execution Time.

          (i) The Company will not (i) take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Company to facilitate the sale or resale of the Offered Units or (ii) sell, bid for, purchase or pay any person (other than as contemplated by this Agreement or any Terms Agreement) any compensation for soliciting purchases of the Offered Units.

          (j) The Company will, at any time during the term of this Agreement, as supplemented from time to time, advise the Manager immediately after it shall have received notice or obtain knowledge thereof, of any information or fact that would alter or affect any opinion, certificate, letter and other document provided to the Manager pursuant to Section 6 herein.

     (iii) such officer has carefully examined the Registration Statement, the Prospectus and the Disclosure Package, and, in such officer’s opinion, (A)(1) the Registration Statement, as of the most recent Effective Date, (2) the Prospectus, as of its date and on the applicable Settlement Date or Time of Delivery, and (3) the Disclosure Package, as of the Applicable Time, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a 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 (B) since the most recent Effective Date, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth; and

     (g) The Company shall have requested and caused the Reserve Engineer to have furnished to the Manager, on every date specified in Section 4(p) hereof and to the extent requested by the Manager in connection with any offering of the Offered Units, letters (which may refer to letters previously delivered to the Manager), dated as of such date, in form and substance reasonably satisfactory to the Manager, covering certain

matters relating to information about the reserves of the Company presented in the Disclosure Package and the Prospectus.

     (h) Since the respective dates as of which information is disclosed in the Registration Statement, the Disclosure Package and the Prospectus, except as otherwise stated therein, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business or properties of the Company and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package (exclusive of any amendment or supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Manager, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Prospectus (exclusive of any amendment or supplement thereto).

     (i) The Company shall have paid the required Commission filing fees relating to the Offered Units within the time period required by Rule 456(b)(1)(i) of the Securities Act without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r) of the Securities Act and, if applicable, shall have updated the “Calculation of Registration Fee” table in accordance with Rule 456(b)(1)(ii) either in a post-effective amendment to the Registration Statement or on the cover page of a prospectus filed pursuant to Rule 424(b).

to the Manager and counsel for the Manager, this Agreement and all obligations of the Manager hereunder may be canceled at, or at any time prior to, any Settlement Date or Time of Delivery, as applicable, by the Manager. Notice of such cancellation shall be given to the Company in writing or by telephone or facsimile confirmed in writing.

          The documents required to be delivered by this Section 6 shall be delivered at the office of Latham & Watkins LLP, counsel for the Manager, at 717 Texas Ave. Suite 1600, Houston, Texas 77002, or electronically if agreed to by the parties, on each such date as provided in this Agreement.

          7. Indemnification and Contribution.

     (a) The Company shall indemnify and hold harmless the Manager, its directors, officers, employees, each person, if any, who controls the Manager within the meaning of Section 15 of the Securities Act, each affiliate of the Manager within the meaning of Rule 405 and each agent of the Manager 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 Offered Units), to which the Manager, director, officer, employee, controlling person, affiliate or any agent of the Manager 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) the registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, (B) the Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto, (C) any Issuer Free Writing Prospectus or any amendment or supplement thereto or (D) 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 Units under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”), (ii) the omission or alleged omission to state in (A) the registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, (B) the Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto, (C) any Issuer Free Writing Prospectus or any amendment or supplement thereto or (D) 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 Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto or the Blue Sky Application, in the light of the circumstances under which they were made) not misleading, and shall reimburse the Manager and each such director, officer, employee, controlling person, affiliate or any agent of the Manager promptly upon demand for any legal or other out-of-pocket expenses reasonably incurred by that Manager, director, officer, employee, controlling person, affiliate or any agent of the Manager 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 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 registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, the Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto, any Issuer Free Writing Prospectus or any amendment or supplement thereto or any Blue Sky application, in reliance upon and in conformity with written information furnished to the Company by the Manager specifically for inclusion therein. The foregoing indemnity agreement is in addition to any liability which the Company may otherwise have to the Manager or to any director, officer, employee, controlling person, affiliate or any agent of the Manager.

     (b) The Manager shall indemnify and hold harmless the Company, its directors, officers and employees, and each person, if any, who controls the Company 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 Company 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 (A) the registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, (B) the Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto, (C) any Issuer Free Writing Prospectus or any amendment or supplement thereto or (D) any Blue Sky Application or (ii) the omission or alleged omission to state in (A) the registration statement for the registration of the Offered Units as originally filed or in any amendment thereof, (B) the Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto, (C) any Issuer Free Writing Prospectus or any amendment or supplement thereto or (D) 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 Base Prospectus, the Prospectus Supplement, the Prospectus or any amendment or supplement thereto or the Blue Sky Application, 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 Company by the Manager specifically for inclusion therein. The foregoing indemnity agreement is in addition to any liability that the Manager may otherwise have to the Company or any such director, officer, employee or controlling person.

     (c) Promptly after receipt by an indemnified party under this Section 7 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 7, 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 7 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 this Section 7. 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 7 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 7 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 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a) or 7(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, on the one hand, and the Manager, on the other, from the offering of the

Offered Units 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, on the one hand, and the Manager, 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, on the one hand, and the Manager, 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 Units purchased under this Agreement (before deducting expenses) received by the Company, as determined by this Agreement or any applicable Terms Agreement, on the one hand, bear to the total underwriting discounts and commissions received by the Manager with respect to the Offered Units purchased under this Agreement, as determined by this Agreement or any applicable Terms Agreement, 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 or the Manager, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company and the Manager agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation 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 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. 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.

          8. Termination.

          (a) The Company shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Units in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if Offered Units have been sold through the Manager for the Company, then Section 4(u) shall remain in full force and effect, (ii) with respect to any pending sale, through the Manager for the Company, the obligations of the Company, including in respect of compensation of the Manager, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

          (b) The Manager shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Units in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that the provisions of Sections 5, 7, 9, 10, 12 and 14 of this Agreement shall remain in full force and effect notwithstanding such termination.

          (c) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a) or (b) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Sections 5, 7 and 9 shall remain in full force and effect.

          (d) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by the Manager or the Company, as the case may be. If such termination shall occur prior to the Settlement Date or Time of Delivery for any sale of the Offered Units, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

          (e) In the case of any purchase of Offered Units by the Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Company prior to the Time of Delivery relating to such Offered Units, if at any time prior to such delivery and payment (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), is such as to make it, in the sole judgment of the Manager, impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

          9. Representations and Indemnities to Survive. The respective agreements, representations, warranties and indemnities of the Company and of the Manager set forth in or made pursuant to this Agreement by or on behalf of them, respectively, will remain in full force and effect, regardless of any investigation made by the Manager or the Company or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Offered Units.

Furthermore, the Company agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Manager has advised or is currently advising the Company on related or other matters). The Company agrees that it will not claim that the Manager has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Company, in connection with such transaction or the process leading thereto.

Dear Sirs:

          Linn Energy, LLC (the “Company”) proposes, subject to the terms and conditions stated herein and in the Equity Distribution Agreement, dated August, [•], 2011 (the “Equity Distribution Agreement”), between the Company and Citigroup Global Markets Inc., to issue and sell to Citigroup Global Markets Inc. the securities specified in the Schedule I hereto (the “Purchased Units”) [, and solely for the purpose of covering over-allotments, to grant to Citigroup Global Markets Inc. the option to purchase the additional securities specified in Schedule I hereto (the “Additional Units”)].

          [Citigroup Global Markets Inc. shall have the right to purchase from the Company all or a portion of the Additional Units as may be necessary to cover over-allotments made in connection with the offering of the Purchased Units, at the same purchase price per Unit to be paid by Citigroup Global Markets Inc. to the Company for the Purchased Units. This option may be exercised by Citigroup Global Markets Inc. at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Company. Such notice shall set forth the aggregate number of Additional Units as to which the option is being exercised, and the date and time when the Additional Units are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date shall not be earlier than the Time of Delivery (as set forth in Schedule I hereto) nor 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. Payment of the purchase price for the Additional Units shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Purchased Units.]

          Each of the provisions of the Equity Distribution Agreement not specifically related to the solicitation by Citigroup Global Markets Inc., as agent of the Company, of offers to purchase securities is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein. Each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Terms Agreement, the Time of Delivery and [any Option Closing Date], except that each representation and warranty in Section 2 of the Equity Distribution Agreement which makes reference to the Prospectus (as therein defined) shall be deemed to be a representation and warranty as of the date of the Equity Distribution Agreement

Annex I - 1

in relation to the Prospectus, and also a representation and warranty as of the date of this Terms Agreement, the Time of Delivery and [any Option Closing Date] in relation to the Prospectus as amended and supplemented to relate to the Purchased Units and provided that such representations and warranties may be updated to reflect such necessary modifications as are not material and approved by the Manager in advance.

          An amendment to the Registration Statement (as defined in the Equity Distribution Agreement), or a supplement to the Prospectus, as the case may be, relating to the Purchased Units [and the Additional Units], in the form heretofore delivered to the Manager is now proposed to be filed with the Securities and Exchange Commission.

          Subject to the terms and conditions set forth herein and in the Equity Distribution Agreement which are incorporated herein by reference, the Company agrees to issue and sell to Citigroup Global Markets Inc. and the latter agrees to purchase from the Company the number of Purchased Units at the time and place and at the purchase price set forth in the Schedule I hereto.

Schedule I to Annex I

EXHIBIT A

FORM OF OPINION OF BAKER BOTTS L.L.P.

     1. Each of the Company and the Subsidiaries that are incorporated or organized in the State of Delaware or the State of Texas (the “DE/TX Subsidiaries”) is validly existing and in good standing as a corporation or limited liability company, as applicable, under the laws of its jurisdiction of incorporation or formation, as applicable, 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 jurisdictions listed on Exhibit A to such opinion.

     2. (a) The Company has the limited liability company power to execute and deliver, and perform its obligations under, this Agreement and any applicable Terms Agreement and (b) each of the Company and the DE/TX 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 Disclosure Package and the Prospectus. The Company has the limited liability company power to authorize, issue, sell and deliver the Offered Units as contemplated by this Agreement and any applicable Terms Agreement.

     3. This Agreement and any applicable Terms Agreement have been duly and validly authorized, executed and delivered by the Company.

     4. The Offered Units to be issued and sold by the Company under this Agreement and any applicable Terms Agreement have been duly authorized in accordance with the Company’s limited liability company agreement and, upon payment and delivery in accordance with this Agreement and any applicable Terms Agreement, will be validly issued, fully paid (to the extent required under the Company’s limited liability company agreement) and non-assessable (except as such non-assessability may be affected by Sections 18-303, 18-607 and 18-804 of the Delaware LLC Act) and will conform in all material respects to the description thereof contained in the Disclosure Package and the Prospectus.

     5. The Delaware LLC Act does not grant holders of Units preemptive rights to subscribe for or purchase the Offered Units. Except as described in the 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 Units pursuant to the Company’s certificate of formation, limited liability company agreement or the agreements filed as exhibits to the Company’s most recent Annual Report on Form 10-K, Quarterly Report on Form 10-Q and any Current Reports on Form 8-K filed since the most recent Annual Report on Form 10-K or the Quarterly Report on Form 10-Q, as applicable (collectively, the “Reviewed Agreements”).

     6. The execution and delivery of this Agreement and any applicable Terms Agreement by the Company, the consummation of the transactions contemplated by the Agreement and any applicable Terms Agreement and the application of the proceeds from the sale of the Offered Units described under “Use of Proceeds” in each of the Disclosure Package and the Prospectus do not, and the performance by the Company of its obligations under this Agreement and any applicable Terms Agreement will not, (a) 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 under, the Reviewed Agreements or (b) 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”), the Texas Limited Liability Company Act (the “Texas LLC Act”) or federal law (the “Included Laws”).

     7. 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 and any applicable Terms Agreement by the Company and the performance by the Company of its obligations under this Agreement and any applicable Terms Agreement, except for (a) routine Filings necessary in connection with the conduct of the business of the Company 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 and any applicable Terms 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 FINRA.

     8. The statements in the Prospectus under the caption “Material Tax Consequences,” insofar as such statements constitute a summary of the United States federal tax laws referred to therein, as of the Execution Date, Applicable Time and the date of the Prospectus, 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, it being understood that such counsel did not participate in the preparation of the registration statement on Form S-3 (Registration Statement No. 333-162357) or the accompanying prospectus dated October 6, 2009 (the “Base Prospectus”), as filed by the Company with the Commission under the Securities Act, and such counsel expresses no view as to the discussion set forth under the caption “Material Tax Consequences” in the Base Prospectus, which is entirely superseded by the statements under the caption “Material Tax Consequences” in the supplement included in the Prospectus; and the opinion of such counsel that will be filed as Exhibit 8.1 to the Form 8-K to be filed with the Commission between the date of this Agreement and the earlier of the initial Settlement Date or the initial Time of Delivery is confirmed, and the Manager may rely upon such opinion as if it were addressed to it.

     9. The Registration Statement is an “automatic shelf registration statement” (as defined in Rule 405) that has been filed with the Commission not earlier than three years prior to the date of this Agreement; the Prospectus was filed with the Commission pursuant to Rule 424(b) on the date specified in such opinion; and, to the knowledge of such counsel, no order suspending the effectiveness of the Registration Statement has been issued, no notice of objection of the Commission to the use of such Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) has been received by the Company and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Company or in connection with the offering is pending or threatened by the Commission.

     10. The statements in the Prospectus under the caption “Description of the Units,” insofar as such statements purport to summarize the legal terms of the Units (including the Offered Units) and the Company’s limited liability company agreement, fairly summarize such terms and such agreement in all material respects, subject to the qualifications and assumptions stated therein. The statements in the Prospectus under the caption “Description of the Units,” 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 states therein.

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

     12. 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 law, the Delaware LLC Act, the DGCL and the Texas LLC Act, (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 Company and the DE/TX Subsidiaries, 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 Settlement Date or Time of Delivery, as the case may be, and shall be provided to the Manager), (E) with respect to the opinion expressed in paragraph 9 above as it relates to the absence of any stop orders suspending the effectiveness of the Registration Statement, state that such counsel has relied solely upon a telephone conference with the staff of the Commission on each Representation Date with respect to the absence of issued stop orders or proceedings for that purpose, (F) state that they express no opinion with respect to any permits to own or operate any real or personal property, (G) 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, (H) 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 (I) state that they express no opinion as to the financial statements, including the notes thereto, and any other financial, pro forma financial and accounting data and reserve information contained or incorporated by reference in the Registration Statement, the Disclosure Package or the Prospectus.

     In addition, such counsel shall also have furnished to the Manager a written statement dated such Representation Date in form and substance satisfactory to the Manager, to the effect that such counsel has reviewed the Registration Statement, the Disclosure Package and the Prospectus and has participated in conferences with officers and other representatives of the

Company, with representatives of the Company’s independent registered public accounting firm and independent petroleum engineer and with your representatives and your counsel, at which the contents of the Registration Statement, the 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 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 Disclosure Package and the Prospectus 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 contained or included in the Registration Statement, the Disclosure Package and the Prospectus (except to the extent stated in paragraphs 8 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 you that:

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

     (b) the documents filed under the Exchange Act and incorporated by reference in the Disclosure Package and the Prospectus or any amendment thereof or supplement thereto (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; and

     (c) nothing came to such counsel’s attention that caused it to believe that:

     (1) the Registration Statement, as of the latest 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 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 Representation 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 report 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.

Exhibit B

FORM OF OPINION OF
GENERAL COUNSEL

     1. All of the outstanding Units of the Company have been duly authorized and validly issued, are fully paid (to the extent required under the Company’s limited liability company agreement) and non-assessable (except as such non-assessability may be affected by Section 18-607 of the Delaware LLC Act), conform to the description thereof contained in 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 Company’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 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 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 (to the extent required under the Company’s limited liability company agreement), non-assessable (except as such non-assessability may be affected by Section 18-607 of the Delaware LLC Act) and are owned directly or indirectly by the Company. To such counsel’s knowledge, (i) the outstanding membership interests or capital stock, as applicable, of the Subsidiaries owned by the Company 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 are outstanding.

     3. Such counsel knows of no material legal or governmental actions, suits or proceedings pending or threatened against the Company or any Subsidiary which would be required by the Securities Act to be disclosed in the Registration Statement except as set forth in the Disclosure Package and the Prospectus. To such counsel’s knowledge, other than as set forth in the Disclosure Package and the Prospectus, there are no legal or governmental proceedings pending to which the Company or its Subsidiaries are a party or of which any property of the Company 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 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 and any person granting such person the right to require the Company to register any securities of the Company owned or to be owned by such person pursuant to the Registration Statement.

     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 her opinion is limited to federal laws, the Delaware LLC Act, the DGCL and the Texas LLC Act, (D) state that she expresses no opinion with respect to any permits to own or operate any real or personal property, (F) state that she expresses 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 and (G) state that she expresses no opinion with respect to state or local taxes or tax statutes to which the Company or any of its Subsidiaries may be subject.
