The representations and warranties in the preceding paragraph do not apply to statements in or omissions from the Offering Memorandum, the General Disclosure Package, any Issuer Free Writing Document or any amendment or supplement to any of the foregoing made in reliance upon and in conformity with written information furnished to the Partnership by any Initial Purchaser through the Representative expressly for use therein, it being understood and agreed that the only such information furnished by the Initial Purchasers as aforesaid consists of the information described as such in Section 6(b) hereof.

(4) Incorporated Documents. The Exchange Act Reports incorporated by reference in the General Disclosure Package or the Offering Memorandum, at the respective times they were or hereafter are filed with the Commission, complied or will comply in all material respects with the requirements of the 1934 Act and the 1934 Act Regulations and did not or will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading.

(5) Reporting Compliance. The Partnership is subject to, and is in full compliance in all material respects with, the reporting requirements of Section 13 and Section 15(d), as applicable, of the 1934 Act.

(6) No Other Securities of Same Class. When the Securities are issued and delivered pursuant to this Agreement, such Securities will not be of the same class (within the meaning of Rule 144A under the 1933 Act) as securities of the Issuers or the Guarantors that are listed on a national securities exchange registered under Section 6 of the 1934 Act or that are quoted in a United States automated inter-dealer quotation system.

(7) No Registration. No registration under the 1933 Act of the Securities is required for the sale of the Securities and to you as contemplated hereby or for the initial resale of Securities by you to the Eligible Purchasers, assuming the accuracy of the Initial Purchasers’ representations in this Agreement.

(9) Regulation S Compliance. Each of the Issuers is a Category 2 issuer for purposes of Regulation S. No directed selling efforts within the meaning of Rule 902 under the 1933 Act were used by the Issuers and their subsidiaries or any of their representatives (other than you, as to whom the Memorial Parties make no representation) with respect to Securities sold in reliance on Regulation S, and the Issuers, any affiliate of the Issuers and any person acting on their behalf (other than you, as to whom the Memorial Parties make no representation) have complied with and will implement the “offering restrictions” required by Rule 902 under the 1933 Act.

(10) No Integration. None of the Partnership Parties nor any other person acting on behalf of the Partnership Parties has sold or issued any securities that would be integrated with the offering of the Securities contemplated by this Agreement in a manner that would require registration of the Securities under the 1933 Act.

(35) Financial Statements. The historical financial statements and schedules of the Partnership (or the predecessor to the Partnership, and of any other entities or businesses constituting a portion of the Partnership Properties included for accounting purposes) included in or incorporated by reference into the General Disclosure Package and the Offering Memorandum present fairly the financial condition, results of operations and cash flows of the predecessor to the Partnership and such other entities or businesses, as applicable, as of the dates and for the periods indicated, comply as to form in all material respects with the applicable accounting requirements of Regulation S-X of the 1933 Act and have been prepared in conformity with GAAP applied on a consistent basis throughout the periods involved (except as otherwise noted therein).

(i) Rule 144A Information. So long as any of the Securities are outstanding, the Issuers and the Guarantors will, during any period in which the Partnership is not subject to Section 13 or 15(d) of the 1934 Act, furnish at their expense to the Initial Purchasers, and, upon request, to the holders of the Securities and prospective purchasers of the Securities the information required by Rule 144A(d)(4) under the 1933 Act (if any).

(o) No Integration. The Issuers will not, and will ensure that no affiliate of the Issuers will, sell, offer for sale or solicit offers to buy or otherwise negotiate in respect of any “security” (as defined in the 1933 Act) that would be integrated with the sale of the Securities in a manner that would require the registration under the 1933 Act of the sale to the Initial Purchasers or to the Eligible Purchasers of the Securities.

(p) Additional Written Communications. Before making, preparing, using, authorizing, approving or referring to any Issuer Free Writing Document, the Issuers and the Guarantors will furnish to the Representative and counsel for the Initial Purchasers a copy of such written communication for review and will not make, prepare, use, authorize, approve or refer to any such written communication to which the Representative reasonably objects.

SECTION 6. Indemnification.

(a) Indemnification by the Memorial Parties. Each of the Memorial Parties agrees, jointly and severally, to indemnify and hold harmless each Initial Purchaser, its affiliates, and its and their officers, directors, employees, agents, partners and members and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act as follows:

(i) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, arising out of or based upon any untrue statement or alleged untrue statement of a material fact in the Preliminary Offering Memorandum, any Issuer Free Writing Document, the General Disclosure Package or the Offering Memorandum (or any amendment or supplement to any of the foregoing), or in any materials, presentations, information or General Solicitation provided to investors by, or with the approval of, any Memorial Party in connection with the marketing of the offering of the Securities, including any road show or investor presentations made to investors by the Partnership (whether in person or electronically), or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

(ii) against any and all loss, liability, claim, damage and expense whatsoever, as incurred, to the extent of the aggregate amount paid in settlement of, or pursuant to a judgment or other disposition in, any litigation, or any investigation or proceeding by any governmental or self-regulatory agency or body, commenced or threatened, or of any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission; provided, that (subject to Section 6(d) below) any such settlement is effected with the written consent of the Memorial Parties; and

(iii) against any and all expense whatsoever (including the fees and disbursements of counsel) reasonably incurred in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental or self-regulatory agency or body, commenced or threatened, or any claim whatsoever arising out of or based upon any such untrue statement or omission, or any such alleged untrue statement or omission, to the extent that any such expense is not paid under (i) or (ii) above,

provided, however, that this indemnity agreement shall not apply to any loss, liability, claim, damage or expense to the extent arising out of or based upon any untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with written information furnished to the Memorial Parties by any Initial Purchaser through the Representative expressly for use in the Preliminary Offering Memorandum, any Issuer Free Writing Document, General Solicitation, the General Disclosure Package or the Offering Memorandum (or in any amendment or supplement to any of the foregoing), it being understood and agreed that the only such information furnished by the Initial Purchasers as aforesaid consists of the information described as such in Section 6(b) hereof.

(b) Indemnification by the Initial Purchasers. Each Initial Purchaser agrees, severally and not jointly, to indemnify and hold harmless the Memorial Parties, their respective directors and each person, if any, who controls the Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act against any and all loss, liability, claim, damage and expense described in the indemnity contained in subsection (a) of this Section 6, as incurred, but only with respect to untrue statements or omissions, or alleged untrue statements or omissions, made in the Preliminary Offering Memorandum, any Issuer Free Writing Document, General Solicitation or the Offering Memorandum (or any amendment or supplement to any of the foregoing), in reliance upon and in conformity with written information furnished to any Memorial Party by any Initial Purchaser through the Representative expressly for use therein. The Memorial Parties hereby acknowledge and agree that the information furnished to any of the Memorial Parties by the Initial Purchasers through the Representative expressly for use in the General Disclosure Package, any Issuer Free Writing Document, General Solicitation or the Offering Memorandum (or any amendment or supplement to any of the foregoing), consists exclusively of the following information appearing under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and the Offering Memorandum: (i) the statements set forth in the table in the first paragraph under such caption, (ii) the statement set forth in the first sentence of the third paragraph under such caption, (iii) the statements set forth in the second sentence of the fourth paragraph under such caption, (iv) the information regarding stabilization,

syndicate covering transactions and penalty bids appearing in the ninth paragraph under such caption (but only insofar as such information concerns the Initial Purchasers), (v) the information regarding market making by the Initial Purchasers appearing in the eighth paragraph under such caption and (vi) the information regarding hedging practices appearing in the twelfth paragraph under such caption.

(c) Actions Against Parties; Notification. Each indemnified party shall give notice as promptly as reasonably practicable to each indemnifying party of any action commenced against it in respect of which indemnity may be sought hereunder; provided, however, that the failure to so notify an indemnifying party shall not relieve such indemnifying party from any liability that it may have under this Section 6 or otherwise. Counsel to the indemnified parties shall be selected as follows: counsel to the Initial Purchasers and the other indemnified parties referred to in Section 6(a) above shall be selected by the Representative; and counsel to the Memorial Parties, their respective directors, each of their respective officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act shall be selected by the Partnership. An indemnifying party may participate at its own expense in the defense of any such action; provided, however, that counsel to the indemnifying party shall not (except with the consent of the indemnified party) also be counsel to the indemnified party. In no event shall the indemnifying party be liable for the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Initial Purchasers and the other indemnified parties referred to in Section 6(a) above; and the fees and expenses of more than one counsel (in addition to any local counsel) separate from their own counsel for the Memorial Parties, their respective directors, each of their respective officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, in each case in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. No indemnifying party shall, without the prior written consent of the indemnified parties, settle or compromise or consent to the entry of any judgment with respect to any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever in respect of which indemnification or contribution could be sought under this Section 6 or Section 7 hereof (whether or not the indemnified parties are actual or potential parties thereto), unless such settlement, compromise or consent (i) includes an unconditional release of each indemnified party from all liability arising out of such litigation, investigation, proceeding or claim and (ii) does not include a statement as to or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party.

(d) Settlement Without Consent if Failure to Reimburse. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel as contemplated by this Section 6, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 6(a)(ii) effected without its written consent if (i) such settlement is entered into more than 45 days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying party shall have received notice of the terms of such settlement at least 30 days prior to such settlement being entered into and (iii) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request prior to the date of such settlement.

SECTION 7. Contribution. If the indemnification provided for in Section 6 hereof is for any reason unavailable to or insufficient to hold harmless an indemnified party in respect of any losses, liabilities, claims, damages or expenses referred to therein, then each indemnifying party shall contribute to the aggregate amount of such losses, liabilities, claims, damages and expenses incurred by such indemnified party, as incurred, (i) in such proportion as is appropriate to reflect the relative benefits received by the Memorial Parties, on the one hand, and the Initial Purchasers, on the other hand, from the offering of the Securities pursuant to this Agreement or (ii) if the allocation provided by clause (i) 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 Memorial Parties, on the one hand, and of the Initial Purchasers, on the other hand, in connection with the statements or omissions which resulted in such losses, liabilities, claims, damages or expenses, as well as any other relevant equitable considerations.

The relative benefits received by the Memorial Parties, on the one hand, and the Initial Purchasers, on the other hand, in connection with the offering of the Securities pursuant to this Agreement shall be deemed to be in the same respective proportions as the total net proceeds from the offering of the Securities pursuant to this Agreement (before deducting expenses) received by the Memorial Parties and the total discounts and commissions received by the Initial Purchasers, in each case as determined pursuant to this Agreement, bear to the aggregate initial offering price of the Securities as set forth on the cover of the Offering Memorandum.

The relative fault of the Memorial Parties, on the one hand, and the Initial Purchasers, on the other hand, shall be determined by reference to, among other things, whether any such 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 Memorial Parties, on the one hand, or by the Initial Purchasers, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

The Memorial Parties and the Initial Purchasers agree that it would not be just and equitable if contribution pursuant to this Section 7 were 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 which does not take account of the equitable considerations referred to above in this Section 7. The aggregate amount of losses, liabilities, claims, damages and expenses incurred by an indemnified party and referred to above in this Section 7 shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in investigating, preparing or defending against any litigation, or any investigation or proceeding by any governmental agency or body, commenced or threatened, or any claim whatsoever based upon any such untrue or alleged untrue statement or omission or alleged omission.

Notwithstanding the provisions of this Section 7, no Initial Purchaser shall be required to contribute any amount in excess of the amount by which the net proceeds from the sale to Eligible Purchasers of the Securities initially purchased by it exceed the amount of any damages which such Initial Purchaser has otherwise been required to pay by reason of any such untrue or alleged untrue statement or omission or alleged omission.

No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 1933 Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

For purposes of this Section 7, each affiliate, officer, director, employee, partner and member of each Initial Purchaser and each person, if any, who controls any Initial Purchaser within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, shall have the same rights to contribution as such Initial Purchaser, and each director of each of the Memorial Parties, each officer of each of the Memorial Parties, and each person, if any, who controls the Partnership within the meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act, shall have the same rights to contribution as the Memorial Parties. The Initial Purchasers’ respective obligations to contribute pursuant to this Section 7 are several in proportion to the principal amount of Notes set forth opposite their respective names in Exhibit A hereto and not joint.

SECTION 8. Representations, Warranties and Agreements to Survive Delivery. All the respective representations, warranties, indemnities and agreements of the Memorial Parties and the Initial Purchasers shall remain operative and in full force and effect, regardless of any investigation made by or on behalf of any Initial Purchaser or the Memorial Parties, and shall survive delivery of and payment for the Securities.

SECTION 9. Termination of Agreement.

(a) Termination; General. The Representative may terminate this Agreement, by notice to the Partnership, at any time on or prior to the Closing Date (i) if there has occurred any material adverse change in the financial markets in the United States or the international financial markets, any declaration of a national emergency or war by the United States, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international political, financial or economic conditions (including, without limitation, as a result of terrorist activities), in each case the effect of which is such as to make it, in the judgment of the Representative, so material and adverse as to make it impracticable or inadvisable to proceed with the offering, sale or delivery of the Securities or to enforce contracts for the sale of the Securities on the terms and in the manner contemplated in the General Disclosure Package and the Offering Memorandum, or (ii) (A) if trading in any securities of the Partnership has been suspended or materially limited by the Commission or the Nasdaq Global Market, or (B) if trading generally on the NYSE, the Nasdaq Global Select Market or the Nasdaq Global Market has been suspended or limited, or minimum or maximum prices for trading have been fixed, or maximum ranges for prices have been required, by any of said exchanges or by order of the Commission or any other governmental authority or (iii) if a banking moratorium has been declared by either Federal or New York authorities.

(b) Liabilities. If this Agreement is terminated pursuant to this Section 9, such termination shall be without liability of any party to any other party except that the Memorial Parties shall be obligated to reimburse the expenses of the Initial Purchasers as provided in Section 4 hereof, and except that Sections 1, 2(d) 6, 7, 8, 11, 12, 13, 14, 15, 17, 18, 19 and 20 hereof shall survive such termination and remain in full force and effect.

SECTION 10. Default by One or More of the Initial Purchasers. If one or more of the Initial Purchasers shall fail at the Closing Date to purchase the aggregate principal amount of Securities which it or they are obligated to purchase under this Agreement (the “Defaulted Securities”), the Representative shall have the right, within 24 hours thereafter, to make arrangements for one or more of the non-defaulting Initial Purchasers, or any other purchaser, to purchase all, but not less than all, of the Defaulted Securities in such amounts as may be agreed upon and upon the terms herein set forth; if, however, the Representative shall not have completed such arrangements within such 24-hour period, then:

(i) if the aggregate principal amount of Defaulted Securities does not exceed 10% of the aggregate principal amount of Securities, each of the non-defaulting Initial Purchasers shall be obligated, severally and not jointly, to purchase the full amount of such Defaulted Securities in the proportions that their respective underwriting obligations hereunder bear to the underwriting obligations of all non-defaulting Initial Purchasers; or

(ii) if the number of Defaulted Securities exceeds 10% of the aggregate principal amount of Securities, this Agreement shall terminate without liability on the part of any non-defaulting Initial Purchaser.

No action taken pursuant to this Section 10 shall relieve any defaulting Initial Purchaser from liability in respect of its default.

In the event of any such default which does not result in a termination of this Agreement, the Representative shall have the right to postpone the Closing Date for a period not exceeding seven days in order to effect any required changes in the General Disclosure Package or Offering Memorandum or in any other documents or arrangements. As used herein, the term “Initial Purchaser” includes any person substituted for an Initial Purchaser under this Section 10.

SECTION 11. Notices. All notices and other communications hereunder shall be in writing, shall be effective only upon receipt and shall be mailed, delivered by hand or overnight courier, or transmitted by fax (with the receipt of any such fax to be confirmed by telephone).

SECTION 12. Parties. This Agreement shall each inure to the benefit of and be binding upon the Initial Purchasers, the Memorial Parties and their respective successors. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any person, firm or corporation, other than the Initial Purchasers, the Memorial Parties and their respective

successors and the controlling persons and other indemnified parties referred to in Sections 6 and 7 and their successors, heirs and legal representatives, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision herein contained. This Agreement and all conditions and provisions hereof are intended to be for the sole and exclusive benefit of the Initial Purchasers, the Memorial Parties and their respective successors, and said controlling persons and other indemnified parties and their successors, heirs and legal representatives, and for the benefit of no other person or entity. No purchaser of Securities from any Initial Purchaser shall be deemed to be a successor by reason merely of such purchase.

Each Partnership Entity (other than Memorial Midstream) is duly qualified to do business as a foreign limited partnership, limited liability company or corporation, as applicable, in, and is in good standing under the laws of or (as to the State of Texas) has the right to transact business in, each jurisdiction (other than the State of Delaware) so identified on Exhibit C attached hereto.

Each Partnership Entity has all requisite entity power and authority to own its respective properties and conduct its business, in each case in all material respects, as described in the Pricing Disclosure Package and the Final Offering Memorandum. Each Partnership Entity has the entity power and authority necessary to execute and deliver the Transaction Documents to which it is a party and perform its obligations under the Transaction Documents to which it is a party. The General Partner has the limited liability company power and authority necessary to act as the general partner of the Partnership.

(a) The execution and delivery of the Transaction Documents by each Partnership Entity party thereto and the performance by each Partnership Entity of its respective obligations under the Transaction Documents to which it is a party has been duly authorized by all necessary corporate or entity action, as applicable, on the part of such Partnership Entity.

(b) Each of the Purchase Agreement, the Indenture and the Registration Rights Agreement has been duly authorized, executed and delivered by each of the Partnership Entities that is a party to such Transaction Document.

No permit, consent, approval, authorization, order, registration, filing or qualification (“Consent”) of or with any court or governmental agency or body under the Included Laws is required in connection with the offering, issuance or sale by the Issuers of the Notes, or the execution, delivery and performance by any of the Specified Partnership Entities of any of the Transaction Documents to which such Specified Partnership Entity is a party or the performance of the actions required to be taken by any of the Specified Partnership Entities pursuant to any of the Transaction Documents to which such Specified Partnership Entity is a party, subject to the assumptions set forth in paragraph 13 and other than (a) such Consents required under state securities or “Blue Sky” laws, (b) such Consents that have been obtained or made, (c) filings with the Commission or other Consents required in the performance by each of the Specified Partnership Entities of its obligations under the Purchase Agreement and (d) Consents required under Federal and state securities laws as provided in the Registration Rights Agreement.

None of the offering, issuance or sale of the Notes by the Issuers, the execution, delivery and performance by any of the Specified Partnership Entities of any of the Transaction Documents to which such Specified Partnership Entity is a party or the performance of the actions required to be taken by any of the Specified Partnership Entities pursuant to any of the Transaction Documents to which such Specified Partnership Entity is party conflicts or will conflict with or constitutes or will constitute a breach or violation of or a default (or an event which, with notice or lapse of time or both, would constitute such a default) under, or results or will result in the creation or imposition of any Lien upon any property or assets of any of the Specified Partnership Entities (other than those arising under the MLP Credit Agreement) pursuant to, (a) any Constitutive Document of any of the Partnership Entities, (b) any Material Agreement, (c) any law, rule or regulation of the Included Laws (including Regulations T, U and X of the Board of Governors of the Federal Reserve System) or (d) any order, judgment, decree or injunction of any court or governmental agency or body known to us directed to any of the Specified Partnership Entities or any of their properties in a proceeding to which any of them or their property is a party; provided, however, that no opinion is expressed pursuant to this paragraph with respect to federal securities laws and other anti-fraud laws.

The Partnership is not and, after giving effect to the Offering and the application of the proceeds therefrom as described in the Pricing Disclosure Package and the Final Offering Memorandum, the Partnership will not be, an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

The statements set forth in the Pricing Disclosure Package and the Final Offering Memorandum under the captions “Description of Notes,” “Description of Other Indebtedness,” “Certain Relationships and Related Party Transactions,” “Transfer Restrictions,” “Certain Material United States Federal Income Tax Considerations” and “Certain ERISA Considerations,” insofar as they summarize any agreement, statute or regulation or refer to statements of law or legal conclusions, are accurate and fair summaries in all material respects. The Indenture and the Notes conform, and the Exchange Notes, when duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, will conform, in all material respects to the descriptions thereof contained in the General Disclosure Package and the Final Offering Memorandum under the caption “Description of Notes.”

9.	The Indenture conforms in all material respects to the requirements of the TIA (as defined below) and the rules and regulations of the Commission applicable to an indenture which is qualified thereunder.

10.

The Notes have been duly and validly authorized and executed by the Issuers and, 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 the Purchase 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 under the Laws of the State of New York.

will constitute valid and legally binding obligations of the Issuers, enforceable against the Issuers in accordance with their respective terms under the Laws of the State of New York.

11.

The Indenture (including, with respect to the Guarantors, (i) when the Notes 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 the Purchase Agreement, the guarantee of the Guarantors in respect of the Notes provided for in Article 10 of the Indenture and (ii) when the Exchange Notes have been duly executed, authenticated, issued and delivered as provided in the Indenture and the Registration Rights Agreement, the guarantee of the Guarantors in respect of the Exchange Notes provided for in Article 10 of the Indenture) constitutes the valid and legally binding obligation of the Specified Partnership Obligors, enforceable against the Specified Partnership Obligors in accordance with its terms under the Laws of the State of New York.

12.	The Registration Rights Agreement is a valid and binding obligation of each of the Specified Partnership Obligors, enforceable against the Specified Partnership Obligors in accordance with its terms under the Laws of the State of New York.

13.

Assuming without independent investigation, (a) that the Notes 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, the Purchase Agreement and the Final Offering Memorandum; (b) the accuracy of the representations and warranties of the Specified Partnership Entities set forth in the Purchase Agreement and the matters certified in those certain certificates delivered on the date hereof; (c) the accuracy of the representations and warranties of the Initial Purchasers set forth in the Purchase Agreement; (d) the due performance and compliance by the Specified Partnership Entities and the Initial Purchasers of their respective covenants and agreements set forth in the Purchase Agreement; and (e) the Initial Purchasers’ compliance with the Final Offering Memorandum and the transfer procedures and restrictions described therein, it is not necessary to register the Notes 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 Notes by the Issuers to the Initial Purchasers or in connection with the offer, resale and delivery of the Notes by the Initial Purchasers in accordance with the terms of and in the manner contemplated by the Purchase Agreement and the Final Offering Memorandum, it being expressly understood that we express no opinion in this paragraph 13 or paragraph 5 as to any subsequent offer or resale of any of the Notes.

Our identification of documents and information as part of the Pricing Disclosure Package has been at your request and with your approval. Such identification is for the limited purpose of making the statements set forth in this letter and is not the expression of a view by us as to whether any such information has been or should have been conveyed to investors generally or to any particular investors at any particular time or in any particular manner.

Because the primary purpose of our professional engagement was not to establish or confirm factual matters, financial, accounting or statistical information or reserve and production

information, and because many determinations involved in the preparation of the Pricing Disclosure Package and the Final Offering Memorandum are of a wholly or partially non-legal character, except as expressly set forth in paragraph 8 of this opinion letter, we are not passing upon and do not assume any responsibility for the accuracy, completeness or fairness of the statements contained or incorporated by reference in the Pricing Disclosure Package and the Final Offering Memorandum and we make no representation that we have independently verified the accuracy, completeness or fairness of such statements.

However, in the course of our acting as counsel to the Partnership in connection with the preparation of the Pricing Disclosure Package and the Final Offering Memorandum, we have reviewed each such document and have participated in conferences and telephone conversations with representatives of the Partnership, representatives of the independent public accountants for the Partnership, representatives of the independent reserve engineers for the applicable Specified Partnership Entities, representatives of the Initial Purchasers and representatives of the Initial Purchasers’ counsel, during which conferences and conversations the contents of such documents and related matters were discussed.

Subject to the foregoing, on the basis of the information we gained in the course of our participation in such conferences and conversations and our review of such documents, we confirm to you that:

(a) The Incorporated Documents, at the time they were filed, appeared on their face to be appropriately responsive in all material respects with the requirements of the Exchange Act, except that (i) we express no view as to the financial statements, the notes and schedules thereto and other financial and accounting data and oil and gas reserve and production information contained or incorporated by reference therein or omitted therefrom, and (ii) we express no view in this sentence as to the antifraud provisions of the U.S. federal securities laws and the rules and regulations promulgated under such provisions.

(b) No information has come to our attention that causes us to believe that (i) the Pricing Disclosure Package, as of [ ] (New York time) on October 7, 2013 (which you have informed us is a time prior to the time of the first sale of the Notes by any Initial Purchaser), contained any untrue statement of a material fact or omitted to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they are made, not misleading or (ii) the Final Offering Memorandum, as of its date and as of the Closing Date, contained or contains any untrue statement of a material fact or omitted or omits to state any material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except that in the case of each of clauses (i)-(ii) above, we do not express any view as to the financial statements, the notes and schedules thereto and other financial and accounting data and oil and gas reserve and production information contained or incorporated by reference therein or omitted therefrom.

(a) Unless the Exchange Offer shall not be permissible under applicable law or Commission policy (after the procedures set forth in Section 6(a) hereof have been complied with), the Issuers and the Guarantors shall (i) cause to be filed with the Commission sufficiently promptly so as to avoid a Registration Default with respect to the Exchange Offer, a Registration

-4-

Statement under the Securities Act relating to the Exchange Securities (other than Transfer Restricted Securities acquired by any Broker-Dealer directly from the Issuers) and the Exchange Offer (the “Exchange Offer Registration Statement”), (ii) use their commercially reasonable efforts to cause such Exchange Offer Registration Statement to become effective under the Securities Act sufficiently promptly so as to avoid a Registration Default with respect to the Exchange Offer, (iii) in connection with the foregoing, file (A) all pre-effective amendments to such Exchange Offer Registration Statement as may be necessary in order to cause such Exchange Offer Registration Statement to become effective, (B) if applicable, a post-effective amendment to such Exchange Offer Registration Statement pursuant to Rule 430A under the Securities Act and (C) cause all necessary filings in connection with the registration and qualification of the Exchange Securities to be made under the state securities or blue sky laws of such jurisdictions as are necessary to permit Consummation of the Exchange Offer, and (iv) upon the effectiveness of such Exchange Offer Registration Statement, as promptly as practicable, commence the Exchange Offer. The Exchange Offer shall be on the appropriate form permitting registration of the Exchange Securities to be offered in exchange for the Transfer Restricted Securities (other than Transfer Restricted Securities acquired by any Broker-Dealer directly from the Issuers) and to permit resales of Transfer Restricted Securities held by Broker-Dealers as contemplated by Section 3(c) hereof.

(b) The Issuers and the Guarantors shall cause the Exchange Offer Registration Statement to be effective continuously and shall keep the Exchange Offer open for a period of not less than the minimum period required under applicable federal and state securities laws to Consummate the Exchange Offer; provided, however, that in no event shall such period be less than 20 Business Days after the date notice of the Exchange Offer is mailed or otherwise delivered to the Holders. The Issuers shall cause the Exchange Offer to comply with all applicable federal and state securities laws. No securities other than the Exchange Securities shall be included in the Exchange Offer Registration Statement. The Issuers and the Guarantors shall use commercially reasonable efforts to cause the Exchange Offer to be Consummated on the earliest practicable date after the Exchange Offer Registration Statement has become effective, but in no event later than days after the Closing Date (or if such ^th day is not a Business Day, the next succeeding Business Day) (such ^th day herein referred to as the “Exchange Deadline”).

(c) The Issuers shall indicate in a “Plan of Distribution” section contained in the Prospectus forming a part of the Exchange Offer Registration Statement that any Broker-Dealer who holds New Securities that are Transfer Restricted Securities that were acquired for its own account as a result of market-making activities or other trading activities (other than Transfer Restricted Securities acquired directly from the Issuers), may exchange such New Securities pursuant to the Exchange Offer; however, such Broker-Dealer may be deemed to be an “underwriter” within the meaning of the Securities Act and must, therefore, deliver a prospectus meeting the requirements of the Securities Act in connection with any resales of the Exchange Securities received by such Broker-Dealer in the Exchange Offer, which prospectus delivery requirement may be satisfied by the delivery by such Broker-Dealer of the Prospectus contained in the Exchange Offer Registration Statement. Such “Plan of Distribution” section shall also contain all other information with respect to such resales by Broker-Dealers that the Commission may require in order to permit such resales pursuant thereto, but such “Plan of Distribution” shall not name any such Broker-Dealer or disclose the amount of New Securities held by any such Broker-Dealer except to the extent required by the Commission.

-5-

The Issuers and the Guarantors shall use commercially reasonable efforts to keep the Exchange Offer Registration Statement continuously effective, supplemented and amended as required by the provisions of Section 6(c) hereof to the extent necessary to ensure that it is available for resales of Transfer Restricted Securities acquired by Broker-Dealers for their own accounts as a result of market-making activities or other trading activities, and to ensure that it conforms with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period ending on the earlier of (i) 180 days from the date on which the Exchange Offer Registration Statement is declared effective and (ii) the date on which a Broker-Dealer is no longer required to deliver a prospectus in connection with market-making or other trading activities; provided that the Partnership may for a period (the “Exchange Offer Registration Statement Suspension Period”) of up to 45 days in any three months period, not to exceed 90 days in any calendar year, determine that the Exchange Offer Registration Statement is not usable under the circumstances relating to corporate developments, public filings with the Commission and similar events, and suspend the use of the Prospectus that is a part of the Exchange Offer Registration Statement.

The Issuers shall provide sufficient copies of the latest version of such Prospectus to Broker-Dealers promptly upon request at any time during such 180-day (or shorter as provided in the foregoing sentence) period in order to facilitate such resales.

SECTION 4. Shelf Registration.

(a) Shelf Registration. If (i) the Issuers and the Guarantors are not required to file an Exchange Offer Registration Statement or to consummate the Exchange Offer for the New Securities because the Exchange Offer is not permitted by applicable law or Commission policy; (ii) for any reason the Exchange Offer for the New Securities is not Consummated by the Exchange Deadline (unless an Exchange Offer Registration Statement has been filed within days of the Closing Date and has not yet been declared effective by the Commission, other than as a result of the fault of any Issuer or Guarantor, and as a result of Commission review of data or information included or incorporated by reference in such Registration Statement that would also be included or incorporated in a Shelf Registration Statement, the Issuers and Guarantors reasonably believe that a Shelf Registration Statement would not become effective prior to consummation of the Exchange Offer); or (iii) with respect to any Holder of Transfer Restricted Securities that is not an Affiliate of the Issuer or Guarantors (A) such Holder is prohibited by applicable law or Commission policy from participating in the Exchange Offer, (B) such Holder may not resell the Exchange Securities acquired by it in the Exchange Offer to the public without delivering a prospectus and that the Prospectus contained in the Exchange Offer Registration Statement is not appropriate or available for such resales by such Holder, or (C) such Holder is a Broker-Dealer and holds New Securities acquired directly from the Issuers or one of their Affiliates, then, upon such Holder’s written request within six months of the first to occur of the Exchange Date or the Exchange Deadline, the Issuers and the Guarantors shall (1) if permitted by law and Commission policy, cause the Transfer Restricted Securities of such Holder to be reissued in a form that does not bear any restrictive legends relating to the Securities Act and

-6-

does not have a restrictive CUSIP number so that such Transfer Restricted Securities may be sold to the public in accordance with Rule 144 under the Securities Act by a person that is not an Affiliate of the Issuer or any of the Guarantors where no conditions of Rule 144 are then applicable (other than the holding period requirement in paragraph (d)(1)(ii) of Rule 144 so long as such holding period requirement is satisfied at such time of such reissue) and (2) in the event the Issuers cannot or do not comply with the provisions of the foregoing clause within 20 Business Days of the later of (I) the date of receipt by the Issuer of such notice of such Holder and (II) the first to occur of the Exchange Date and the Exchange Deadline (such later date being a “Shelf Filing Deadline”), then the Issuers and the Guarantors shall:

(x) as promptly as practicable cause to be filed a shelf registration statement pursuant to Rule 415 under the Securities Act, which may be an amendment to the Exchange Offer Registration Statement (in either event, the “Shelf Registration Statement”) on or prior to the Shelf Filing Deadline which Shelf Registration Statement shall provide for resales of all Transfer Restricted Securities the Holders of which shall have provided the information required pursuant to Section 4(b) hereof; and

(y) use their commercially reasonable efforts to cause such Shelf Registration Statement to be declared effective by the Commission on or before the 90th day after the Shelf Filing Deadline (or if such 90th day is not a Business Day, the next succeeding Business Day).

Each of the Issuers and the Guarantors shall keep any such Shelf Registration Statement continuously effective, supplemented and amended as required by the provisions of Sections 6(b) and (c) hereof to the extent necessary to ensure that it is available for resales of New Securities by the Holders of Transfer Restricted Securities by the Holders entitled to the benefit of this Section 4(a), and to ensure that it conforms in all material respects with the requirements of this Agreement, the Securities Act and the policies, rules and regulations of the Commission as announced from time to time, for a period of one year following the effective date of such Shelf Registration Statement (or such shorter period that will terminate when all the New Securities covered by such Shelf Registration Statement have been sold pursuant to such Shelf Registration Statement or may be sold without a restrictive legend pursuant to Rule 144 under the Securities Act or any successor rule). Each of the Issuers and the Guarantors shall be deemed not to have used commercially reasonable efforts to keep the Shelf Registration Statement effective during the requisite period if any of the Issuers or the Guarantors voluntarily takes any action that would result in Holders of Transfer Restricted Securities covered thereby not being able to offer and sell such Transfer Restricted Securities during that period, unless (X) such action is required by applicable law or Commission policy; or (Y) such action is taken by any of the Issuers or Guarantors in good faith and for valid business reasons (not including avoidance of the Issuers or the Guarantors obligations hereunder) including, but not limited to, the acquisition or divestiture of assets, so long as the Issuers and the Guarantors promptly thereafter comply with the requirements of the last paragraph of Section 6(c) hereof (the period during which the Shelf Registration Statement is not available under clauses (X) or (Y) above, the “Blackout Period”). The Blackout Period shall not exceed 45 days in any three-month period or 90 days in any twelve-month period.

-7-

(b) Provision by Holders of Certain Information in Connection with the Shelf Registration Statement. No Holder of Transfer Restricted Securities may include any of its Transfer Restricted Securities in any Shelf Registration Statement pursuant to this Agreement unless and until such Holder furnishes to the Issuers in writing, within ten Business Days after receipt of a request therefor, such information as the Issuers may reasonably request for use in connection with any Shelf Registration Statement or Prospectus or preliminary Prospectus included therein. Each Holder as to which any Shelf Registration Statement is being effected agrees to furnish promptly to the Issuers all information required to be disclosed in order to make the information previously furnished to the Issuers by such Holder not materially misleading.

SECTION 5. Additional Interest. If (i) the Exchange Offer is not Consummated on or prior to the Exchange Deadline, (ii) a Shelf Registration Statement applicable to the Transfer Restricted Securities required to be filed by the terms of this Agreement is not declared effective (or does not automatically become effective) on or prior to the 90th calendar day following any Shelf Filing Deadline (or if such 90th day is not a Business Day, the next succeeding Business Day), or (iii) a Shelf Registration Statement applicable to the Transfer Restricted Securities required to be filed by the terms of this Agreement is declared effective (or automatically becomes effective) as required but thereafter fails to remain effective or becomes unusable in connection with resales for more than 30 calendar days, excluding any Blackout Period (each such event referred to in clauses (i) through (iii) above, a “Registration Default”), the Issuers hereby agree that the interest rate borne by the Transfer Restricted Securities shall be increased by 0.25% per annum for the first 90-day period immediately following the Exchange Deadline and by an additional 0.25% per annum with respect to each subsequent 90-day period, in each case for the period of occurrence of the Registration Default, up to a maximum additional interest rate of 1.00% per annum thereafter (“Additional Interest”), until the earlier of the consummation of the Exchange Offer and such time as no Registration Default is in effect, plus such additional amount of time as is required under the last sentence of Section 6(c), upon which Additional Interest will cease to accrue and the interest rate on the Transfer Restricted Securities will revert to the original rate; provided, however, that, if after the date such Additional Interest ceases to accrue, another Registration Default occurs, Additional Interest will again commence accruing pursuant to the foregoing provisions. In no event will Additional Interest accrue under more than one of the foregoing clauses (i), (ii) and (iii) at any one time; provided, however, that the amount of Additional Interest accruing on the Transfer Restricted Securities shall not exceed, in any event, 1.00% per annum. The obligations of the Issuers and the Guarantors to pay Additional Interest as set forth in this Section 5 shall be the sole and exclusive remedy of the Holders for any Registration Default.

All obligations of the Issuers and the Guarantors set forth in the preceding paragraph that are outstanding with respect to any Transfer Restricted Security at the time such security ceases to be a Transfer Restricted Security shall survive until such time as all such obligations with respect to such security shall have been satisfied in full.

SECTION 6. Registration Procedures.

(a) Exchange Offer Registration Statement. In connection with the Exchange Offer, the Issuers and the Guarantors shall comply with all of the applicable provisions of Section 6(c)

-8-

hereof, shall use commercially reasonable efforts to effect such exchange to permit the sale of Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof. As a condition to its participation in the Exchange Offer pursuant to the terms of this Agreement, each Holder of Transfer Restricted Securities shall furnish, upon the request of the Issuers, prior to the Consummation thereof, a written representation to the Issuers (which may be contained in the letter of transmittal contemplated by the Exchange Offer Registration Statement) to the effect that (A) it is not an affiliate (within the meaning of Rule 405 under the Securities Act) of the Issuers or the Guarantors, (B) it is not engaged in, and does not intend to engage in, and has no arrangement or understanding with any Person to participate in, a distribution (within the meaning of the Securities Act) of the Exchange Securities to be issued in the Exchange Offer and (C) it is acquiring the Exchange Securities in its ordinary course of business. In addition, all such Holders of Transfer Restricted Securities shall otherwise cooperate in the Issuers’ preparations for the Exchange Offer. Each Holder hereby acknowledges and agrees that any Broker-Dealer and any such Holder using the Exchange Offer to participate in a distribution of the securities to be acquired in the Exchange Offer (1) could not under Commission policy as in effect on the date of this Agreement rely on the position of the Commission enunciated in Morgan Stanley and Co., Inc. (available June 5, 1991) and Exxon Capital Holdings Corporation (available May 13, 1988), as interpreted in the Commission’s letter to Shearman & Sterling dated July 2, 1993, and similar no-action letters, and (2) must comply with the registration and prospectus delivery requirements of the Securities Act in connection with a secondary resale transaction and that such a secondary resale transaction should be covered by an effective registration statement containing the selling security holder information required by Item 507 or 508, as applicable, of Regulation S-K if the resales are of Exchange Securities obtained by such Holder in exchange for New Securities acquired by such Holder directly from the Issuers.

(b) Shelf Registration Statement. In connection with any Shelf Registration Statement, each of the Issuers and the Guarantors shall comply with all the provisions of Section 6(c) hereof and shall use commercially reasonable efforts to effect such registration to permit the sale of the Transfer Restricted Securities being sold in accordance with the intended method or methods of distribution thereof, and pursuant thereto each of the Issuers and the Guarantors will as expeditiously as possible, when required, prepare and file with the Commission a Registration Statement relating to the registration on any appropriate form under the Securities Act, which form shall be available for the sale of the Transfer Restricted Securities in accordance with the intended method or methods of distribution thereof.

(c) General Provisions. In connection with any Registration Statement and any Prospectus required by this Agreement to permit the sale or resale of Transfer Restricted Securities (including, without limitation, any Registration Statement and the related Prospectus required to permit resales of New Securities by Broker-Dealers), each of the Issuers and the Guarantors shall:

(i) use commercially reasonable efforts to keep such Registration Statement continuously effective and provide all requisite financial statements (including, if required by the Securities Act or any regulation thereunder, financial statements of the Guarantors) for the period specified in Section 3 or 4 hereof, as applicable; upon the

-9-

occurrence of any event that would cause any such Registration Statement or the Prospectus contained therein (A) to contain a material misstatement or omission or (B) not to be effective and usable for resale of Transfer Restricted Securities during the period required by this Agreement, the Issuers shall file promptly an appropriate amendment to such Registration Statement (or file with the Commission a document to be incorporated by reference into the Registration Statement), in the case of clause (A), correcting any such misstatement or omission, and, in the case of either clause (A) or (B), use commercially reasonable efforts to cause such amendment to be declared effective and such Registration Statement and the related Prospectus to become usable for their intended purposes as soon as practicable thereafter, subject to the provisions applicable to Exchange Offer Registration Statement Suspension Periods and Blackout Periods and the last paragraph hereof;

(ii) prepare and file with the Commission such amendments and post-effective amendments to the applicable Registration Statement as may be necessary to keep the Registration Statement effective for the applicable period set forth in Section 3 or 4 hereof, as applicable, or such shorter period as will terminate when all Transfer Restricted Securities covered by such Registration Statement have been sold; cause the Prospectus to be supplemented by any required prospectus supplement, and as so supplemented to be filed pursuant to Rule 424 under the Securities Act, and to comply fully with the applicable provisions of Rules 424, 430A and 430B under the Securities Act in a timely manner; and comply in all material respects with the provisions of the Securities Act with respect to the disposition of all securities covered by such Registration Statement during the applicable period in accordance with the intended method or methods of distribution by the sellers thereof set forth in such Registration Statement or supplement to the Prospectus;

(iii) in the case of a Shelf Registration Statement, advise the underwriters, if any, and selling Holders promptly and, if requested by such Persons, to confirm such advice in writing, (A) when the Prospectus or any prospectus supplement or post-effective amendment has been filed, and, with respect to any Registration Statement or any post-effective amendment thereto, when the same has become effective, (B) of any request by the Commission for amendments to the Registration Statement or amendments or supplements to the Prospectus or for additional information relating thereto, (C) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement under the Securities Act or of the suspension by any state securities commission of the qualification of the Transfer Restricted Securities for offering or sale in any jurisdiction, or the initiation of any proceeding for any of the preceding purposes, and (D) of the existence of any fact or the happening of any event that makes any statement of a material fact made in the Registration Statement, the Prospectus, any amendment or supplement thereto, or any document incorporated by reference therein untrue, or that requires the making of any additions to or changes in the Registration Statement or the Prospectus in order to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, or any state securities commission or other

-10-

regulatory authority shall issue an order suspending the qualification or exemption from qualification of the Transfer Restricted Securities under state securities or blue sky laws, each of the Issuers and the Guarantors shall use commercially reasonable efforts to obtain the withdrawal or lifting of such order at the earliest possible time;

(iv) in the case of a Shelf Registration Statement, furnish without charge to each of the Initial Purchasers, each selling Holder named in any Registration Statement if so requested by such Holder, and each underwriter, if any, before filing with the Commission, copies of any Registration Statement or any Prospectus included therein or any amendments or supplements to any such Registration Statement or Prospectus (including all documents incorporated by reference after the initial filing of such Registration Statement), which documents will be subject to the review and comment of such Holders and underwriters in connection with such sale, if any, for a period of at least five Business Days, and the Issuers will not file any such Registration Statement or Prospectus or any amendment or supplement to any such Registration Statement or Prospectus (including all such documents incorporated by reference) to which an Initial Purchaser of Transfer Restricted Securities covered by such Registration Statement or the underwriters, if any, shall reasonably object in writing within five Business Days after the receipt thereof (such objection to be deemed timely made upon confirmation of telecopy transmission within such period); provided, that this clause (iv) shall not apply to any filing by the Partnership of any annual report on Form 10-K, quarterly report on Form 10-Q or Current Report on Form 8-K with respect to matters unrelated to the New Securities, the Transfer Restricted Securities and the Exchange Securities and the offering or exchange therefor. The objection of an Initial Purchaser or an underwriter, if any, shall be deemed to be reasonable if such Registration Statement, amendment, Prospectus or supplement, as applicable, as proposed to be filed, contains a material misstatement or omission;

(v) in the case of a Shelf Registration Statement, make available during normal business hours for inspection by the Initial Purchasers, the managing underwriters, if any, participating in any disposition pursuant to such Registration Statement and any attorney or accountant retained by such Initial Purchasers or any of the underwriters, all financial and other records, pertinent corporate documents and properties of each of the Issuers and the Guarantors and cause the Issuers’ and the Guarantors’ officers, directors and employees to supply all information reasonably requested by any such Holder, underwriter, attorney or accountant in connection with such Registration Statement or any post-effective amendment thereto subsequent to the filing thereof (and each such Person shall agree that it will keep such information confidential and not disclose any such records, documents, properties or information unless (A) the disclosure of such records, documents, properties or information is, in the opinion of counsel to such Person, necessary to avoid or correct a misstatement or omission in such Registration Statement, (B) the release of such records, documents, properties or information is ordered pursuant to a subpoena or other order from a court of competent jurisdiction, (C) the records, documents, properties or information in such records is public or has been made generally available to the public other than as a result of a disclosure or failure to safeguard by such Person or (D) disclosure of such records,

-11-

documents, properties or information is, in the opinion of counsel for any such Person, necessary or advisable in connection with any action, claim, suit or proceeding, directly or indirectly, involving such Person and arising out of, based upon, related to, or involving this Agreement, or any transaction contemplated hereby or arising hereunder) and prior to its effectiveness and to participate in meetings with investors to the extent requested by the managing underwriters, if any, if in connection with the Underwritten Offering of Transfer Restricted Securities of an aggregate principal amount of $100,000,000 or greater;

(vi) in connection with an Underwritten Offering, if requested by any selling Holders or the underwriters, if any, promptly incorporate in any Registration Statement or Prospectus, pursuant to a supplement or post-effective amendment if necessary, such information as such selling Holders and underwriters, if any, may reasonably request to have included therein, including, without limitation, information relating to the “Plan of Distribution” of the Transfer Restricted Securities, information with respect to the principal amount of Transfer Restricted Securities being sold to such underwriters, the purchase price being paid therefor and any other terms of the offering of the Transfer Restricted Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after the Issuers are notified of the matters to be incorporated in such prospectus supplement or post-effective amendment, subject to the provisions applicable to the Exchange Offer Registration Statement Suspension Periods and Blackout Periods and the last paragraph hereof;

(ix) in the case of a Shelf Registration Statement, enter into such customary agreements (including an underwriting agreement in form, scope and substance as is customary in underwritten offerings of debt securities similar to the Transfer Restricted Securities, as may be appropriate in the circumstances), and make such representations and warranties, and take all such other actions in connection therewith as is customary in offerings of debt securities similar to the Transfer Restricted Securities in order to

-12-

expedite or facilitate the disposition of the Transfer Restricted Securities pursuant to any Registration Statement contemplated by this Agreement, all to such extent as may be reasonably requested by any Initial Purchaser or by any Holder of Transfer Restricted Securities or underwriter in connection with any sale or resale pursuant to any Registration Statement contemplated by this Agreement; and, whether or not an underwriting agreement is entered into and whether or not the registration is an Underwritten Registration, each of the Issuers and the Guarantors shall:

(A) furnish to each Initial Purchaser, each selling Holder and each underwriter, if any, in such substance and scope as they may request and as are customarily made by issuers to underwriters in primary underwritten offerings, upon the effectiveness of the Shelf Registration Statement:

Without limiting the foregoing,

-13-

such counsel may state further that such counsel assumes no responsibility for, and has not independently verified, the accuracy, completeness or fairness of the financial statements, notes and schedules and other financial, accounting and reserve data included in any Shelf Registration Statement contemplated by this Agreement or the related Prospectus;

If at any time the representations and warranties of the Issuers and the Guarantors contemplated in Section 6(c)(ix)(A)(1) hereof cease to be true and correct, the Issuers or the Guarantors shall so advise the Initial Purchasers and the underwriters, if any, and each selling Holder promptly and, if requested by such Persons, shall confirm such advice in writing;

(x) in the case of a Shelf Registration Statement, prior to any public offering of Transfer Restricted Securities pursuant to a Shelf Registration Statement, cooperate with the selling Holders, the underwriters, if any, and their respective counsel in connection with the registration and qualification of the Transfer Restricted Securities under the state securities or blue sky laws of such jurisdictions as the selling Holders or underwriters, if any, may reasonably request and do any and all other acts or things

-14-

necessary or advisable to enable the disposition in such jurisdictions of the Transfer Restricted Securities covered by the Shelf Registration Statement; provided, however, that none of the Issuers nor the Guarantors shall be required to register or qualify as a foreign entity where it is not then so qualified or to take any action that would subject it to the service of process in suits or to taxation in any jurisdiction where it is not then so subject;

(xi) shall issue, upon the request of any Holder of New Securities covered by the Exchange Offer Registration Statement, in connection with the Consummation of the Exchange Offer and in accordance with the Indenture, Exchange Securities having an aggregate principal amount equal to the aggregate principal amount of New Securities surrendered to the Issuers by such Holder in exchange therefore;

(xii) in connection with an Underwritten Offering, cooperate with the selling Holders and the underwriters, if any, to facilitate the timely preparation and delivery of certificates representing Transfer Restricted Securities to be sold and not bearing any restrictive legends; and enable such Transfer Restricted Securities to be in such denominations and registered in such names as the Holders or the underwriters, if any, may request at least two Business Days prior to any sale of Transfer Restricted Securities made by such Holders or underwriters;

(xiii) in the case of a Shelf Registration Statement, use commercially reasonable efforts to cause the Transfer Restricted Securities covered by the Registration Statement to be registered with or approved by such other domestic governmental agencies or authorities as may be necessary to enable the seller or sellers thereof or the underwriters, if any, to consummate the disposition of such Transfer Restricted Securities, subject to the proviso contained in Section 6(c)(x) hereof;

(xiv) if any fact or event contemplated by Section 6(c)(iii)(D) hereof shall exist or have occurred, prepare a supplement or post-effective amendment to the Registration Statement or related Prospectus or any document incorporated therein by reference or file any other required document so that, as thereafter delivered to the purchasers of Transfer Restricted Securities, the Prospectus will not contain an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading, subject to the provisions applicable to Exchange Offer Registration Statement Suspension Periods and Blackout Periods and the last paragraph hereof;

(xv) provide a CUSIP number for all Exchange Securities not later than the effective date of the Registration Statement covering such Exchange Securities and provide the Trustee under the Indenture with printed certificates for such Exchange Securities which are in a form eligible for deposit with the Depository Trust Company and take all other action reasonably necessary to ensure that all such Exchange Securities are eligible for deposit with the Depository Trust Company;

(xvi) cooperate and assist in any filings required to be made with the FINRA and in the performance of any due diligence investigation by any underwriter (including

-15-

any “qualified independent underwriter” as that term is defined within the rules and regulations of the FINRA) that is required to be retained in accordance with the rules and regulations of the FINRA;

(xvii) otherwise use commercially reasonable efforts to comply in all material respects with all applicable rules and regulations of the Commission, and make generally available to its security holders, as soon as reasonably practicable, a consolidated earnings statement meeting the requirements of Rule 158 under the Securities Act (which need not be audited) for the twelve-month period (A) commencing at the end of any fiscal quarter in which Transfer Restricted Securities are sold to underwriters in a firm commitment or best efforts Underwritten Offering or (B) if not sold to underwriters in such an offering, beginning with the first month of the Issuers’ first fiscal quarter commencing after the effective date of the Registration Statement;

(xviii) cause the Indenture to be qualified under the Trust Indenture Act not later than the effective date of the first Registration Statement required by this Agreement, and, in connection therewith, cooperate with the Trustee and the Holders of the New Securities to effect such changes to the Indenture as may be required for such Indenture to be so qualified in accordance with the terms of the Trust Indenture Act; and to execute and use commercially reasonable efforts to cause the Trustee to execute, all documents that may be required to effect such changes and all other forms and documents required to be filed with the Commission to enable such Indenture to be so qualified in a timely manner; and

(xix) in the case of a Shelf Registration Statement, cause all Transfer Restricted Securities covered by such Shelf Registration Statement to be listed on each securities exchange or automated quotation system on which similar securities issued by the Issuers are then listed if requested by the Holders of a majority in aggregate principal amount of New Securities or the managing underwriters, if any.

Each Holder agrees by acquisition of a Transfer Restricted Security that, upon receipt of any notice from the Issuers of the existence of any fact of the kind described in Section 6(c)(iii)(D) hereof or any Exchange Offer Registration Statement Suspension Period described in Section 3(c) or any Blackout Period described in Section 4(a) hereof, such Holder will forthwith discontinue disposition of Transfer Restricted Securities pursuant to the applicable Registration Statement until such Holder’s receipt of the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xiv) hereof, or until it is advised in writing (the “Advice”) by the Issuers that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. If so directed by the Issuers, each Holder will deliver to the Issuers (at the Issuers’ expense) all copies, other than permanent file copies then in such Holder’s possession, of the Prospectus covering such Transfer Restricted Securities that was current at the time of receipt of such notice. In the event the Issuers shall give any such notice, the time period regarding the effectiveness of such Registration Statement set forth in Section 3 or 4 hereof, as applicable, shall be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 6(c)(iii)(D) hereof or notice of any Exchange Offer Registration Statement

-16-

Suspension Period and Blackout Period to and including the date when each selling Holder covered by such Registration Statement shall have received the copies of the supplemented or amended Prospectus contemplated by Section 6(c)(xiv) hereof or shall have received the Advice.

SECTION 7. Registration Expenses.

(a) All expenses incident to the Issuers’ and the Guarantors’ performance of or compliance with this Agreement will be borne by the Issuers and the Guarantors, jointly and severally, regardless of whether a Registration Statement becomes effective, including, without limitation: (i) all registration and filing fees and expenses (including filings made by any Initial Purchaser or Holder with the FINRA (and, if applicable, the fees and expenses of any “qualified independent underwriter” and its counsel that may be required by the rules and regulations of the FINRA)); (ii) all fees and expenses of compliance with federal securities and state securities or blue sky laws; (iii) all expenses of printing (including printing certificates for the Exchange Securities to be issued in the Exchange Offer and printing of Prospectuses), if any, messenger and delivery services and telephone; (iv) all fees and disbursements of counsel for the Issuers, the Guarantors and, subject to Section 7(b) hereof, the Holders of Transfer Restricted Securities; (v) all fees and disbursements of independent certified public accountants of the Issuers and the Guarantors (including the expenses of any special audit and comfort letters required by or incident to such performance); (vi) all application and filing fees in connection with listing the Exchange Securities on a securities exchange or automated quotation system pursuant to the requirements thereof; and (vii) all fees and disbursements of the Trustee and its counsel; provided that all underwriting discounts and commissions and transfer taxes, if any, relating to the sale or disposition of a Holder’s Transfer Restricted Securities pursuant to a Shelf Registration Statement shall be the responsibility of each Holder.

Each of the Issuers and the Guarantors will, in any event, bear its internal expenses (including, without limitation, all salaries and expenses of its officers and employees performing legal or accounting duties), the expenses of any annual audit and the fees and expenses of any Person, including special experts, retained by the Issuers or the Guarantors.

(b) In connection with any Shelf Registration Statement required by this Agreement, the Issuers and the Guarantors, jointly and severally, will reimburse the Initial Purchasers and the Holders of Transfer Restricted Securities being registered pursuant to the Shelf Registration Statement, as applicable, for the reasonable fees and disbursements of not more than one counsel, who shall be Latham & Watkins LLP or such other counsel as may be chosen by the Holders of a majority in principal amount of the Transfer Restricted Securities for whose benefit such Registration Statement is being prepared.

SECTION 8. Indemnification.

(a) The Issuers and the Guarantors, jointly and severally, agree to indemnify and hold harmless (i) each Holder and (ii) each Person, if any, who controls (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) any Holder (any of the Persons referred to in this clause (ii) being hereinafter referred to as a “controlling person”) and (iii) the respective officers, directors, partners, employees, representatives and agents of any Holder or any controlling person (any Person referred to in clause (i), (ii) or (iii) may hereinafter

-17-

be referred to as an “Indemnified Holder”), to the fullest extent lawful, from and against any and all losses, claims, damages or liabilities (or actions in respect thereof) including, without limitation, and as incurred, reimbursement of each such Indemnified Holder for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim damage, liability or action, joint or several, directly or indirectly arising out of or based upon any untrue statement or alleged untrue statement of a material fact contained in any Registration Statement or Prospectus (or any amendment or supplement thereto), or any omission or alleged omission to state therein a material fact required to be stated therein (in the case of the Registration Statement or any amendment or supplement thereto) or necessary to make the statements therein (with respect to the Prospectus, in light of the circumstances under which they were made) not misleading, except insofar as such losses, claims, damages, liabilities or actions are caused by an untrue statement or omission or alleged untrue statement or omission that is made in reliance upon and in conformity with information relating to any of the Holders furnished in writing to the Issuers by any of the Holders expressly for use therein. This indemnity agreement shall be in addition to any liability which the Issuers or any of the Guarantors may otherwise have.

In case any action or proceeding (including any governmental or regulatory investigation or proceeding) shall be brought or asserted against any of the Indemnified Holders with respect to which indemnity may be sought against the Issuers or the Guarantors, such Indemnified Holder (or the Indemnified Holder controlled by such controlling person) shall promptly notify the Issuers and the Guarantors in writing; provided, however, that the failure to give such notice shall not relieve the Issuers or any of the Guarantors of their respective obligations pursuant to this Agreement. Such Indemnified Holder shall have the right to employ its own counsel in any such action and the fees and expenses of such counsel shall be paid, as incurred, by the Issuers and the Guarantors (regardless of whether it is ultimately determined that an Indemnified Holder is not entitled to indemnification hereunder). The Issuers and the Guarantors shall not, in connection with any one such action or proceeding or separate but substantially similar or related actions or proceedings in the same jurisdiction arising out of the same general allegations or circumstances, be liable for the reasonable fees and expenses of more than one separate firm of attorneys (in addition to any local counsel) at any time for such Indemnified Holders, which firm shall be reasonably designated by the Holders. The Issuers and the Guarantors shall not be liable to any indemnified party for any settlement 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, action, suit or proceeding) unless such settlement, compromise or consent is consented to by the Issuers and the Guarantors in writing. The Issuers and the Guarantors shall not, without the prior written consent of each Indemnified Holder, settle or compromise or consent to the entry of judgment in or otherwise seek to terminate any pending or threatened action, claim, litigation or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not any Indemnified Holder is a party thereto), unless such settlement, compromise, consent or termination (i) includes an unconditional release of each Indemnified Holder from all liability arising out of such action, claim, litigation or proceeding and (ii) does not include any statements as to or any findings of fault, culpability or failure to act by or on behalf of any indemnified party.

-18-

(b) Each Holder agrees, severally and not jointly, to indemnify and hold harmless the Issuers, the Guarantors and their respective directors, officers of the Issuers and the Guarantors who sign a Registration Statement, and any Person controlling (within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act) the Issuers or any of the Guarantors, and the respective officers, directors, partners, employees, representatives and agents of each such Person, to the same extent as the foregoing indemnity from the Issuers and the Guarantors to each of the Indemnified Holders, but only with respect to claims and actions based on information relating to such Holder furnished in writing by such Holder expressly for use in any Registration Statement or Prospectus (or any amendment or supplement thereto). In case any action or proceeding shall be brought against the Issuers, the Guarantors or their respective directors or officers or any such controlling person in respect of which indemnity may be sought against a Holder of Transfer Restricted Securities, such Holder shall have the rights and duties given the Issuers and the Guarantors, and the Issuers, the Guarantors, their respective directors and officers and such controlling person shall have the rights and duties given to each Holder by the preceding paragraph. This indemnity agreement shall be in addition to any liability that the Holders of Transfer Restricted Securities may otherwise have.

(c) If the indemnification provided for in this Section 8 is unavailable to an indemnified party under Section 8(a) or (b) hereof (other than by reason of exceptions provided in those Sections) in respect of any losses, claims, damages, liabilities or actions referred to therein, then each applicable indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities in such proportion as is appropriate to reflect the relative benefits received by the Issuers and the Guarantors, on the one hand, and the Holders, on the other hand, from the Initial Placement (which in the case of the Issuers and the Guarantors shall be deemed to be equal to the total gross proceeds to the Issuers and the Guarantors from the Initial Placement and in the case of the Holders shall be deemed to be equal to the total discount received by such Holder with respect to the New Securities), the amount of Additional Interest which did not become payable as a result of the filing of the Registration Statement resulting in such losses, claims, damages, liabilities or actions, and such Registration Statement, or if such allocation is not permitted by applicable law, the relative fault of the Issuers and the Guarantors, on the one hand, and the Holders, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative fault of the Issuers and the Guarantors on the one hand and of the Indemnified Holder on the other shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Issuers or any of the Guarantors, on the one hand, or the Indemnified Holders, on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, claims, damages, liabilities and actions referred to above shall be deemed to include, subject to the limitations set forth in the second paragraph of Section 8(a) hereof, any legal or other fees or expenses reasonably incurred by such party in connection with investigating or defending any action or claim.

-19-

The Issuers, the Guarantors and each Holder agree that it would not be just and equitable if contribution pursuant to this Section 8(c) were determined by pro rata allocation (even if the Holders were treated as one entity for such purpose) or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities or actions referred to in the immediately preceding paragraph shall be deemed to include, subject to the limitations set forth above, 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, none of the Holders (and its related Indemnified Holders) shall be required to contribute, in the aggregate, any amount in excess of the amount by which the total discount received by such Holder with respect to the New Securities exceeds the amount of any damages which such Holder has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. The Holders’ obligations to contribute pursuant to this Section 8(c) are several in proportion to the respective principal amount of New Securities held by each of the Holders hereunder and not joint.

SECTION 9. Rule 144A. Each of the Issuers and the Guarantors hereby agrees with each Holder, for so long as any Transfer Restricted Securities remain outstanding, if the Partnership is no longer required to file reports under the Exchange Act, to make available upon request to any Holder or beneficial owner of Transfer Restricted Securities in connection with any sale thereof and any prospective purchaser of such Transfer Restricted Securities from such Holder or beneficial owner, the information required by Rule 144A(d)(4) under the Securities Act in order to permit resales of such Transfer Restricted Securities pursuant to Rule 144A under the Securities Act.

SECTION 10. Participation in Underwritten Registrations. No Holder may participate in any Underwritten Registration hereunder unless such Holder (a) agrees to sell such Holder’s Transfer Restricted Securities on the basis provided in any underwriting arrangements approved by the Persons entitled hereunder to approve such arrangements and (b) completes and executes all reasonable questionnaires, powers of attorney, indemnities, underwriting agreements, lock-up letters and other documents required under the terms of such underwriting arrangements.

SECTION 11. Selection of Underwriters. The Holders of Transfer Restricted Securities covered by the Shelf Registration Statement who desire to do so may sell such Transfer Restricted Securities in an Underwritten Offering. In any such Underwritten Offering, the investment bankers and managing underwriter(s) that will administer such offering will be selected by the Holders of a majority in aggregate principal amount of the Transfer Restricted Securities included in such offering; provided, however, that such investment banker(s) and managing underwriters must be reasonably satisfactory to the Issuers.

-20-

SECTION 12. Miscellaneous.

(a) Remedies. Each of the Issuers and the Guarantors hereby agrees that monetary damages would not be adequate compensation for any loss incurred by reason of a breach by it of the provisions of this Agreement and hereby agree to waive the defense in any action for specific performance that a remedy at law would be adequate.

(b) No Inconsistent Agreements. Each of the Issuers and the Guarantors will not on or after the date of this Agreement enter into any agreement with respect to its securities that is inconsistent with the rights granted to the Holders in this Agreement or otherwise conflicts with the provisions hereof. The rights granted to the Holders hereunder do not in any way conflict with and are not inconsistent with the rights granted to the holders of the Issuers’ or any of the Guarantors’ securities under any agreement in effect on the date hereof.

(c) Adjustments Affecting the Securities. The Issuers will not take any action, or permit any change to occur, with respect to the New Securities that would materially and adversely affect the ability of the Holders to Consummate any Exchange Offer.

(d) Amendments and Waivers. The provisions of this Agreement may not be amended, modified or supplemented, and waivers or consents to or departures from the provisions hereof may not be given unless the Issuers have (i) in the case of Section 5 hereof and this Section 12(d)(i), obtained the written consent of Holders of all outstanding Transfer Restricted Securities and (ii) in the case of all other provisions hereof, obtained the written consent of Holders of a majority of the outstanding principal amount of Transfer Restricted Securities (excluding any Transfer Restricted Securities held by the Issuers or its Affiliates). Notwithstanding the foregoing, a waiver or consent to departure from the provisions hereof that relates exclusively to the rights of Holders whose securities are being tendered pursuant to the Exchange Offer and that does not affect directly or indirectly the rights of other Holders whose securities are not being tendered pursuant to such Exchange Offer may be given by the Holders of a majority of the outstanding principal amount of Transfer Restricted Securities being tendered or registered; provided, however, that, with respect to any matter that directly or indirectly affects the rights of any Initial Purchaser hereunder, the Issuers shall obtain the written consent of Wells Fargo Securities LLC, as representative of the Initial Purchasers, with respect to which such amendment, qualification, supplement, waiver, consent or departure is to be effective.

ANNEX I

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 1933 Act. The Initial Purchaser agrees that, during such 40-day restricted period, it will not cause any advertisement with respect to the Securities (including any “tombstone” advertisement) to be published in any newspaper or periodical or posted in any public place and will not issue any circular relating to the Securities, except such advertisements as are permitted by and include the statements required by Regulation S.

Such Initial Purchaser agrees that, at or prior to confirmation of a sale of Securities by it to any distributor, dealer or person receiving a selling concession, fee or other remuneration during the 40-day restricted period referred to in Rule 903 of Regulation S, it will send to such distributor, dealer or person receiving a selling concession, fee or other remuneration a confirmation or notice to substantially the following effect:

“The Securities covered hereby have not been registered under the U.S. Securities Act of 1933, as amended (the “Securities Act”), and may not be offered and sold within the United States or to, or for the account or benefit of, U.S. persons (i) as part of your distribution at any time or (ii) otherwise until 40 days after the later of the date the Securities were first offered to persons other than distributors in reliance on Regulation S and the Closing Date, except in either case in accordance with Regulation S under the Securities Act (or in accordance with Rule 144A under the Securities Act or to accredited investors in transactions that are exempt from the registration requirements of the Securities Act), and in connection with any subsequent sale by you of the Securities covered hereby in reliance on Regulation S under the Securities Act during the period referred to above to any distributor, dealer or person receiving a selling concession, fee or other remuneration, you must deliver a notice to substantially the foregoing effect. Terms used above have the meanings assigned to them in Regulation S under the Securities Act.”

Such Initial Purchaser agrees that the Securities offered and sold in reliance on Regulation S will be represented upon issuance by a global security that may not be exchanged for definitive securities until the expiration of the 40-day restricted period referred to in Rule 903 of Regulation S and only upon certification of beneficial ownership of such Securities by non-U.S. persons or U.S. persons who purchased such Securities in transactions that were exempt from the registration requirements of the 1933 Act.
