7.      Indemnification and Contribution.

(a)   Indemnification of the Purchasers. The Partnership Entities hereby agree, jointly and severally, to indemnify and hold harmless each Purchaser, its affiliates, directors, officers and employees and each person, if any, who controls any Purchaser within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof (including, but not limited to, any loss, claim, damage, liability or action relating to purchases and sales of the Notes), to which that Purchaser, affiliate, director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in (A) the Preliminary Offering Memorandum or the Final Offering Memorandum or in any

amendment or supplement thereto (including, without limitation, any Supplemental Marketing Material), (B) any Issuer Free Writing Communication or in any amendment or supplement thereto, (C) any Exchange Act report, or (D) any Blue Sky application or other document prepared or executed by the Partnership (or based upon any written information furnished by the Partnership for use therein) specifically for the purpose of qualifying any or all of the Notes under the securities laws of any state or other jurisdiction (any such application, document or information being hereinafter called a “Blue Sky Application”) or (ii) the omission or alleged omission to state in the Preliminary Offering Memorandum or the Final Offering Memorandum, any Issuer Free Writing Communication or in any amendment or supplement thereto, any Supplemental Marketing Material, any Exchange Act report or in any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, and shall reimburse each Purchaser and each such affiliate, director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Purchaser, affiliate, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that none of the Partnership Entities shall be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Preliminary Offering Memorandum, the Final Offering Memorandum, any Issuer Free Writing Communication or in any such amendment or supplement thereto, any Supplemental Marketing Material, any Exchange Act report or in any Blue Sky Application, in reliance upon and in conformity with written information concerning such Purchaser furnished to the Partnership through the Representative by or on behalf of any Purchaser specifically for inclusion therein, which information consists solely of the information specified in Section 7(e). The foregoing indemnity agreement is in addition to any liability which the Partnership may otherwise have to any Purchaser or to any affiliate, director, officer, employee or controlling person of that Purchaser.

(b)  Indemnification of the Partnership Entities. Each Purchaser, severally and not jointly, shall indemnify and hold harmless each Partnership Entity, its directors, officers and employees, and each person, if any, who controls such Partnership Entity within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, from and against any loss, claim, damage or liability, joint or several, or any action in respect thereof, to which such Partnership Entity or any such director, officer, employee or controlling person may become subject, under the Securities Act or otherwise, insofar as such loss, claim, damage, liability or action arises out of, or is based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Preliminary Offering Memorandum, the Final Offering Memorandum, any Issuer Free Writing Communication or in any amendment or supplement thereto or in any Blue Sky Application, or (ii) the omission or alleged omission to state in the Preliminary Offering Memorandum, the Final Offering Memorandum, any Issuer Free Writing Communication or in any amendment or supplement thereto or in any Blue Sky Application, any material fact required to be stated therein or necessary to make the statements therein not misleading, but in each case only to the extent that the untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information concerning such Purchaser furnished to the Partnership through the Representative by or on behalf of that Purchaser specifically for inclusion therein, which information is limited to the information set forth in Section 7(e). The foregoing indemnity agreement is in addition to any liability that any Purchaser may otherwise have to the Partnership or any such director, officer, employee or controlling person.

(c)  Actions against Parties; Notification. Promptly after receipt by an indemnified party under this Section 7 of notice of any claim or the commencement of any action, the indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under this Section 7, notify the indemnifying party in writing of the claim or the commencement of that action; provided, however, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have under this Section 7 except to the extent it has been materially prejudiced (through the forfeiture of substantive rights and defenses) by such failure and, provided, further, that the failure to notify the indemnifying party shall not relieve it from any liability which it may have to an indemnified party otherwise than under this Section 7. If any such claim or action shall be brought against an indemnified party, and it shall notify the indemnifying party thereof, the indemnifying party

shall be entitled to participate therein and, to the extent that it wishes, jointly with any other similarly notified indemnifying party, to assume the defense thereof with counsel reasonably satisfactory to the indemnified party. After notice from the indemnifying party to the indemnified party of its election to assume the defense of such claim or action, the indemnifying party shall not be liable to the indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the indemnified party shall have the right to employ separate counsel to represent jointly the indemnified party and those other indemnified parties and their respective directors, officers, employees and controlling persons who may be subject to liability arising out of any claim in respect of which indemnity may be sought under this Section 7 if (i) the indemnified party and the indemnifying party shall have so mutually agreed; (ii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party; (iii) the indemnified party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the indemnifying party; or (iv) the named parties in any such proceeding (including any impleaded parties) include both the indemnified parties, on the one hand, and the indemnifying party, on the other hand, and representation of both sets of parties by the same counsel would be inappropriate due to actual or potential differing interests between them, and in any such event the fees and expenses of such separate counsel shall be paid by the indemnifying party. No indemnifying party shall (x) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), settle or compromise or consent to the entry of any judgment with respect to any pending or threatened claim, action, suit or proceeding in respect of which indemnification or contribution may be sought hereunder (whether or not the indemnified parties are actual or potential parties to such claim or action) unless such settlement, compromise or consent includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to, or an admission of fault, culpability or a failure to act by or on behalf of any indemnified party, or (y) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, 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 Section 7(a) or (b) hereof, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d)  Contribution. If the indemnification provided for in this Section 7 shall for any reason be unavailable to or insufficient to hold harmless an indemnified party under Section 7(a), or 7(b) in respect of any loss, claim, damage or liability, or any action in respect thereof, referred to therein, then each indemnifying party shall, in lieu of indemnifying such indemnified party, contribute to the amount paid or payable by such indemnified party as a result of such loss, claim, damage or liability, or action in respect thereof, (i) in such proportion as shall be appropriate to reflect the relative benefits received by the Partnership Entities, on the one hand, and the Purchasers, on the other, from the offering of the Offered Securities, or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Entities, on the one hand, and the Purchasers, on the other, with respect to the statements or omissions that resulted in such loss, claim, damage or liability, or action in respect thereof, as well as any other relevant equitable considerations. The relative benefits received by the Partnership Entities, on the one hand, and the Purchasers, on the other, with respect to such offering shall be deemed to be in the same proportion as the total net proceeds from the offering of the Offered Securities purchased under this Agreement (before deducting expenses) received by the Partnership Entities, on the one hand, and the total discounts and commissions received by the Purchasers with respect to the Offered Securities purchased under this Agreement, on the other hand. The relative fault shall be determined by reference to whether the untrue or

alleged untrue statement of a material fact or omission or alleged omission to state a material fact relates to information supplied by the Partnership Entities or the Purchasers, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The Partnership Entities and the Purchasers agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation (even if the Purchasers were treated as one entity for such purpose) or by any other method of allocation that does not take into account the equitable considerations referred to herein. The amount paid or payable by an indemnified party as a result of the loss, claim, damage or liability, or action in respect thereof, referred to above in this Section 7(d) shall be deemed to include, for purposes of this Section 7(d), any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 7(d), in no event shall a Purchaser be required to contribute any amount in excess of the amount by which the total discounts and commissions received by such Purchaser with respect to the offering of the Offered Securities exceeds the amount of any damages that such Purchaser 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 Purchasers’ obligations to contribute as provided in this Section 7(d) are several in proportion to their respective purchasing obligations hereunder and not joint. For purposes of this Section 7(d), each director, affiliate, officer and employee of a Purchaser and each person, if any, who controls a Purchaser within the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as such Purchaser, and each director of the Partnership Entities, and each person, if any, who controls any of the Partnership Entities with the meaning of the Securities Act and the Exchange Act shall have the same rights to contribution as the Partnership Entities.

(e)  The Purchasers severally confirm and the Partnership Entities acknowledge and agree that the third paragraph, the second sentence of the ninth paragraph, the eleventh paragraph and the twelfth paragraph, in each case under the caption “Plan of Distribution” in the Preliminary Offering Memorandum and Final Offering Memorandum constitute the only information concerning such Purchasers furnished in writing to the Partnership by or on behalf of the Purchasers specifically for inclusion in the Preliminary Offering Memorandum, Final Offering Memorandum, any Issuer Free Writing Communication, any Blue Sky Applications, any Exchange Act reports or in any amendment or supplement thereto.

(f)  The remedies provided for in this Section 7 are not exclusive and shall not limit any rights or remedies that may otherwise be available to any indemnified party at law or in equity.

8.      Default of Purchasers. If any Purchaser or Purchasers default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Purchaser or Purchasers agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities that the Purchasers are obligated to purchase on the Closing Date, the Representative may make arrangements satisfactory to the Partnership for the purchase of such Offered Securities by other persons, including any of the Purchasers, but if no such arrangements are made by the Closing Date, the non-defaulting Purchasers shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Purchasers agreed but failed to purchase on the Closing Date. If any Purchaser or Purchasers so default and the aggregate principal amount of Offered Securities with respect to which such default or defaults occur exceeds 10% of the total principal amount of Offered Securities that the Purchasers are obligated to purchase on the Closing Date and arrangements satisfactory to the Representative and the Partnership for the purchase of such Offered Securities by other persons are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Purchaser or the Partnership, except as provided in Section 9 hereof. As used in this Agreement, the term “Purchaser” includes any person substituted for a Purchaser under this Section 8. Nothing herein will relieve a defaulting Purchaser from liability for its default.

9.      Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Partnership Entities or their respective officers and of the several Purchasers set forth in or made pursuant to this Agreement will remain in full

force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Purchaser, the Partnership Entities or any of their respective representatives, officers or directors or any controlling person, and will survive delivery of and payment for the Offered Securities. If this Agreement is terminated pursuant to Section 8 or if for any reason the purchase of the Offered Securities by the Purchasers is not consummated, the Partnership Entities shall remain responsible for the expenses to be paid or reimbursed by them pursuant to Section 4 and the respective obligations of the Partnership Entities and the Purchasers pursuant to Section 7 shall remain in effect. If the purchase of the Offered Securities by the Purchasers is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 8 or the occurrence of any event specified in clause (i)(A), (ii), (iii) or (iv) of Section 6(e), the Partnership Entities will reimburse the Purchasers for all out-of-pocket expenses (including fees and disbursements of counsel) reasonably incurred by them in connection with the offering of the Offered Securities. In addition, if any Offered Securities have been purchased hereunder, the representations and warranties in Section 1 and all obligations under Section 4 shall remain in effect.

10.  Notices. All communications hereunder will be in writing and, if sent to the Purchasers will be mailed, hand-delivered, telecopied or transmitted electronically and confirmed to the Purchasers, Wells Fargo Securities, LLC, 550 S. Tryon Street, 5th Floor, Charlotte, North Carolina 28202, Attention: Leveraged Syndicate, or by email at: IBCMDCMLSHYLeveragedSyndicate@wellsfargo.com, or, if sent to any of the Partnership Entities, will be mailed, hand-delivered, telecopied or transmitted electronically and confirmed to 500 West Texas, Suite 1200, Midland, Texas 79701, Attention: P. Matt Zmigrosky; provided, however, that any notice to a Purchaser pursuant to Section 7 will be mailed, hand-delivered, telecopied or transmitted electronically and confirmed to such Purchaser.

11.      Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the officers, directors and controlling persons referred to in Section 7, and no other person will have any right or obligation hereunder, except that holders of the Offered Securities shall be entitled to enforce the agreements for their benefit contained in the second and third sentences of Section 4(b) and the last sentence in Section 4(d) hereof against the Partnership Entities as if such holders were parties thereto.

12.      Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but all such counterparts shall together constitute one and the same Agreement. This Agreement constitutes the entire agreement of the parties to this Agreement and supersedes all prior written or oral and all contemporaneous oral agreements, understandings and negotiations with respect to the subject matter hereof. Any signature to this Agreement may be delivered by facsimile, electronic mail (including pdf) or any electronic signature complying with the U.S. Federal ESIGN Act of 2000 or the New York Electronic Signature and Records Act or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes to the fullest extent permitted by applicable law. Each of the parties hereto represents and warrants to the other parties that it has the capacity and authority to execute this Agreement through electronic means. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

13.      Representation of Purchasers. The Representative will act for the several Purchasers in connection with the transactions contemplated by this Agreement, and any action under this Agreement taken by the Representative will be binding upon all the Purchasers.

14.       Absence of Fiduciary Relationship. Each of the Partnership Entities acknowledges and agrees that:

(a)  No Other Relationship. The Purchasers have been retained solely to act as initial purchasers in connection with the initial purchase, offering and resale of the Offered Securities and that no fiduciary, advisory or agency relationship between any of the Partnership Entities, on the one hand, and any Purchaser, on the other, has been created in respect of any of the transactions contemplated by this Agreement, the Preliminary Offering Memorandum or the Final Offering Memorandum, irrespective of whether any Purchaser has advised or are advising any of the Partnership Entities on other matters;

(b)  Arm’s-Length Negotiations. The purchase price of the Offered Securities set forth in this Agreement was established by the Partnership Entities following discussions and

arm’s-length negotiations with the Representative and the Partnership Entities are capable of evaluating and understanding and understand and accept the terms, risks and conditions of the transactions contemplated by this Agreement;

(c)   Absence of Obligation to Disclose. Each of the Partnership Entities has been advised that each Purchaser and its affiliates are engaged in a broad range of transactions which may involve interests that differ from those of the Partnership Entities and that each Purchaser has no obligation to disclose such interests and transactions to the Partnership Entities by virtue of any fiduciary, advisory or agency relationship; and

(d)  Waiver. Each of the Partnership Entities waives, to the fullest extent permitted by law, any claims it may have against any Purchaser for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Purchasers shall have no liability (whether direct or indirect) to the Partnership Entities in respect of such a fiduciary duty claim or to any person asserting a fiduciary duty claim on behalf of or in right of the Partnership Entities, including members, stockholders, employees or creditors of the Partnership Entities.

15.      Applicable Law. This Agreement, and any claim, controversy or dispute arising under or related to this Agreement, shall be governed by, and construed in accordance with, the laws of the State of New York.

Each of the Partnership Entities hereby submits to the non-exclusive jurisdiction of the Federal and state courts in the Borough of Manhattan in The City of New York in any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby. Each of the Partnership Entities irrevocably and unconditionally waives any objection to the laying of venue of any suit or proceeding arising out of or relating to this Agreement or the transactions contemplated hereby in Federal and state courts in the Borough of Manhattan in The City of New York and irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such suit or proceeding in any such court has been brought in an inconvenient forum. THE PARTNERSHIP ENTITIES HEREBY AGREE ON THEIR OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF THEIR SECURITY HOLDERS, TO WAIVE ANY RIGHT TO A TRIAL BY JURY WITH RESPECT TO ANY CLAIM, COUNTER-CLAIM OR ACTION ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY (INCLUDING, WITHOUT LIMITATION, THE OFFERING).

16.  Recognition of the U.S. Special Resolution Regimes.

(a)  In the event that any Purchaser that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Purchaser of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b)  In the event that any Purchaser that is a Covered Entity or a BHC Act Affiliate of such Purchaser becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Purchaser are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

17.  Patriot Act. In accordance with the requirements of the USA PATRIOT Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)), the Purchasers are required to obtain, verify and record information that identifies their respective clients, including the Partnership Entities, which information may include the name and address of their respective clients, as well as other information that will allow the Purchasers to properly identify their respective clients.

If the foregoing is in accordance with the Purchasers’ understanding of our agreement, kindly sign and return to one of the counterparts hereof, whereupon it will become a binding agreement among the Partnership Entities and the several Purchasers in accordance with its terms.

                        

    

                        

The foregoing Purchase Agreement is hereby confirmed and accepted as of the date first above written.
