The Partnership will use the net proceeds received in connection with this offering in the manner described in the “Use of Proceeds” section of the General Disclosure Package and the Final Prospectus and, except as disclosed in the General Disclosure Package and the Final Prospectus, the Partnership does not intend to use any of the proceeds from the sale of the Offered Securities hereunder to repay any outstanding debt owed to any affiliate of any Underwriter.

     (k) Absence of Manipulation . Neither the Partnership nor any of its affiliates will take, either alone or with one or more other persons, any action that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any securities of the Partnership to facilitate the sale or resale of the Offered Securities.

     (l) Conditions Under this Agreement. The Partnership will do and perform all things required to be done and performed under this Agreement by it and satisfy all conditions precedent on its part to the delivery of the Offered Securities.

     (n) Filing Fees . The Partnership will pay the applicable Commission filing fees relating to the Offered Securities within the time required by Rule 456(b)(1) of the Rules and Regulations without regard to the proviso therein.

     6.  Free Writing Prospectuses .

     (a) Issuer Free Writing Prospectus . The Partnership represents and agrees that, unless it obtains the prior consent of Credit Suisse, and each Underwriter represents and agrees that, unless it obtains the prior consent of the Partnership and Credit Suisse, it has not made and will not make any offer relating to the Offered Securities that would constitute an Issuer Free Writing Prospectus, or that would otherwise constitute a “free writing prospectus,” as defined in Rule 405, required to be filed with the Commission. Any such free writing prospectus consented to by the Partnership and Credit Suisse is hereinafter referred to as a “ Permitted Free Writing Prospectus .” The Partnership represents that it has treated and agrees that it will treat each Permitted Free Writing Prospectus as an “issuer free writing prospectus,” as defined in Rule 433, and has complied and will comply with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including timely filing with the Commission where required, legending and record keeping.

     (b) Term Sheets . The Partnership will prepare a final term sheet substantially in the form of Exhibit B-1 to Schedule B hereto relating to the Offered Securities containing only information that describes the final terms of the Offered Securities or their offering and otherwise in a form consented to by Credit Suisse, and will file such final term sheet with the Commission within the period required by Rule 433(d)(5)(ii) following the date such final terms have been established for the Offered Securities. Any such final term sheet is an Issuer Free Writing Prospectus and a Permitted Free Writing Prospectus for purposes of this Agreement. The Partnership also consents to the use by any Underwriters of a free writing prospectus that contains only (i)(A) information describing the preliminary terms of the Offered Securities or their offering, (B) information permitted by Rule 134, or (C) information that describes the final terms of the Offered Securities or their offering and that is included in the final term sheet of the Partnership contemplated in the first sentence of this subsection or (ii) other information that is not “issuer information,” as defined in Rule 433, it being understood that any such free writing prospectus referred to in clause (i) or (ii) above shall not be an Issuer Free Writing Prospectus for purposes of this Agreement.

     7.  Conditions of the Obligations of the Underwriters . The obligations of the several Underwriters to purchase and pay for the Offered Securities on the Closing Date will be subject to the accuracy of the representations and warranties of the Partnership herein (as though made on the Closing Date), to the accuracy of the statements of officers of the Partnership Entities made pursuant to the provisions hereof, to the performance by the Partnership of its obligations hereunder and to the following additional conditions precedent:

     (a) Accountants’ Comfort Letter . At the time of execution of this Agreement, the Underwriters shall have received from each of Grant Thornton LLP and KPMG LLP a letter, in form and substance satisfactory to the Representatives, addressed to the Underwriters and dated the date hereof (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, and (ii)

stating, as of the date hereof (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the General Disclosure Package and the Final Prospectus, as of a date not more than five days prior to the date hereof), the conclusions and findings of such firm with respect to the financial information and other matters ordinarily covered by accountants’ “comfort letters” to underwriters in connection with public offerings of securities.

With respect to the letters of Grant Thornton LLP and KPMG LLP referred to in the preceding paragraph and delivered to the Underwriters concurrently with the execution of this Agreement (the “ initial letter ”), the Partnership shall have furnished to the Underwriters a letter (the “ bring-down letter ”) of each of Grant Thornton LLP and KPMG LLP, addressed to the Underwriters and dated the Closing Date (i) confirming that they are independent public accountants within the meaning of the Securities Act and are in compliance with the applicable requirements relating to the qualification of accountants under Rule 2-01 of Regulation S-X of the Commission, (ii) stating, as of the date of the bring-down letter (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the General Disclosure Package and the Final Prospectus, as of a date not more than five days prior to the date of the bring-down letter), the conclusions and findings of such firm with respect to the financial information and other matters covered by the initial letter and (iii) confirming in all material respects the conclusions and findings set forth in the initial letter.

     (b) Filing of Prospectus . The Final Prospectus shall have been filed with the Commission in accordance with the Rules and Regulations and Section 5(a) hereof. No stop order suspending the effectiveness of the Registration Statement or of any part thereof shall have been issued and no proceedings for that purpose shall have been instituted or, to the knowledge of the Partnership or any Underwriter, shall be contemplated by the Commission.

     (c) No Material Adverse Change . Subsequent to the execution and delivery of this Agreement, there shall not have occurred: (i) any change, or any development or event involving a prospective change, in the condition (financial or otherwise), results of operations, business, properties or prospects of any of the Partnership and its subsidiaries taken as a whole which, in the judgment of the Representatives, is material and adverse and makes it impractical or inadvisable to market the Offered Securities; (ii) any downgrading in the rating of any debt securities of the Partnership by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) as in effect on July 20, 2010), or any public announcement that any such organization has under surveillance or review its rating of any debt securities of the Partnership (other than an announcement with positive implications of a possible upgrading, and no implication of a possible downgrading, of such rating) or any announcement that the Partnership has been placed on negative outlook; (iii) any change in U.S. or international financial, political or economic conditions or currency exchange rates or exchange controls the effect of which is such as to make it, in the judgment of the Representatives, impractical to market or to enforce contracts for the sale of the Offered Securities, whether in the primary market or in respect of dealings in the secondary market; (iv) any suspension or material limitation of trading in securities generally on the New York Stock Exchange, or any setting of minimum or maximum prices for trading on such exchange; (v) any suspension of trading of any securities of the Partnership on any exchange or in the over-the-counter market; (vi) any banking moratorium declared by any U.S. federal or New York authorities; (vii) any major disruption of settlements of securities, payment, or clearance services in the United States; or (viii) any attack on, outbreak or escalation of hostilities or act of terrorism involving the United States, any declaration of war by Congress or any other national or international calamity or emergency if, in the judgment of the Representatives, the effect of any such attack, outbreak, escalation, act, declaration, calamity or emergency is such as to make it in the judgment of the Representatives impractical or inadvisable to market the Offered Securities or to enforce contracts for the sale of the Offered Securities.

     (d) Opinion of Counsel for the Partnership . The Underwriters shall have received an opinion, dated as of the Closing Date, of Latham & Watkins LLP, counsel for the Partnership, that is substantially to the effect set forth in Schedule E hereto.

     (e) Opinion of Counsel for the Underwriters . The Underwriters shall have received from Andrews Kurth LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date, with respect to such matters as the Representatives may require, and the Partnership shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters.

     (f) Officers’ Certificate . The Underwriters shall have received a certificate, dated as of the Closing Date, of a principal executive officer and a principal financial or accounting officer of the General Partner in which such officers shall state that: (i) the representations and warranties of the Partnership in this Agreement are true and correct; (ii) the Partnership has complied with all agreements and satisfied all conditions on its part to be performed or satisfied hereunder at or prior to the Closing Date; (iii) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the best of their knowledge and after reasonable investigation, are contemplated by the Commission; and (iv) subsequent to the date of the most recent financial statements in the General Disclosure Package, there has been no material adverse change, nor any development or event involving a prospective material adverse change, in the condition (financial or otherwise), results of operations, business, properties or prospects of each of the Partnership Entities and its respective subsidiaries taken as a whole except as set forth in the General Disclosure Package and the Final Prospectus.

     (g) Indenture . The Partnership and the Trustee shall have executed the Indenture and the Underwriters shall have received copies thereof.

     (h) Compliance with DTC Blanket Representation Letter . All agreements set forth in the blanket letter of representations of the Partnership to DTC relating to the approval of the Offered Securities by DTC for “book entry” transfer shall have been complied with.

     Each of the Partnership Entities, as applicable, will furnish the Underwriters with such conformed copies of such opinions, certificates, letters and documents as the Underwriters reasonably request. Credit Suisse may in its sole discretion waive on behalf of the Underwriters compliance with any conditions to the obligations of the Underwriters hereunder.

     8.  Indemnification and Contribution . (a) Indemnification of Underwriters . The Partnership shall indemnify and hold harmless each Underwriter, its officers, employees, agents, partners, members, directors and affiliates of any Underwriter who have, or who are alleged to have, participated in the distribution of the Offered Securities as underwriters, and each person, if any, who controls such Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “ Indemnified Party ”), against any and all losses, claims, damages or liabilities, joint or several, to which such Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus (which term includes any base prospectus and any preliminary prospectus supplement) as of any time, the Final Prospectus or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or alleged omission of a material fact required to be stated therein or necessary in order to make the statements therein, in the case of any Statutory Prospectus or the Final Prospectus, in the light of the circumstances under which they were made, not misleading, and will reimburse each Indemnified Party for any legal or other expenses reasonably incurred by such Indemnified Party in connection with investigating, preparing or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Indemnified Party is a party thereto), whether threatened or commenced, and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred; provided, however , that the Partnership shall be

liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement in or omission or alleged omission from any of such documents in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through Credit Suisse specifically for use therein, it being understood and agreed that the only such information consists of the information described as such in subsection (b) below.

          (b) Indemnification of Partnership . Each Underwriter shall severally and not jointly indemnify and hold harmless the Partnership, its directors and officers and each person, if any, who controls the Partnership within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act (each, an “ Underwriter Indemnified Party ”), against any losses, claims, damages or liabilities to which such Underwriter Indemnified Party may become subject, under the Securities Act, the Exchange Act, other Federal or state statutory law or regulation or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any part of the Registration Statement at any time, any Statutory Prospectus (which term includes any base prospectus and any preliminary prospectus supplement) as of any time, the Final Prospectus, or any Issuer Free Writing Prospectus, or arise out of or are based upon the omission or the alleged omission of a material fact required to be stated therein or necessary in order to make the statements therein, in the case of any Statutory Prospectus or the Final Prospectus, in the light of the circumstances under which they were made, not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to the Partnership by any Underwriter through Credit Suisse specifically for use therein, and will reimburse any legal or other expenses reasonably incurred by such Underwriter Indemnified Party in connection with investigating, preparing or defending against any such loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such Underwriter Indemnified Party is a party thereto), whether threatened or commenced, based upon any such untrue statement or omission, or any such alleged untrue statement or omission as such expenses are incurred, it being understood and agreed that the only such information furnished by any Underwriter consists of the following information in the Final Prospectus furnished on behalf of each Underwriter: (i) the statements regarding the concession and reallowance figures appearing in the third paragraph under the caption “Underwriting” and (ii) the information relating to stabilization appearing in the sixth paragraph under the caption “Underwriting;” provided, however , that the Underwriters shall not be liable for any losses, claims, damages or liabilities arising out of or based upon the Partnership’s failure to perform its obligations under Sections 5(a), (b) or (c) of this Agreement.

          (c) Actions against Parties; Notification . Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under subsection (a) or (b) above, notify the indemnifying party of the commencement thereof; but the failure to notify the indemnifying party shall not relieve it from any liability that it may have under subsection (a) or (b) above except to the extent that it has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure; and provided further that the failure to notify the indemnifying party shall not relieve it from any liability that it may have to an indemnified party otherwise than under subsection (a) or (b) above. In case any such action is brought against any indemnified party and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened action in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party unless such settlement includes (i) an unconditional release of such indemnified party from all liability on any claims that are the subject

matter of such action and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

          (d) Contribution . If the indemnification provided for in this Section is unavailable or insufficient to hold harmless an indemnified party under subsection (a) or (b) above, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of the losses, claims, damages or liabilities referred to in subsection (a) or (b) above (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and the Underwriters 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 on the one hand and the Underwriters on the other 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 benefits received by the Partnership on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total discounts and commissions received by the Underwriters from the Partnership under this Agreement. The relative fault 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 Partnership or the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The amount paid by an indemnified party as a result of the losses, claims, damages or liabilities referred to in the first sentence of this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any action or claim which is the subject of this subsection (d). Notwithstanding the provisions of this subsection (d), no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Offered Securities purchased by it were resold exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. The Underwriters’ obligations in this subsection (d) to contribute are several in proportion to their respective purchase obligations and not joint. The Partnership and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8(d) were determined by pro rata allocation (even if the Underwriters 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 this Section 8(d).

     9.  Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Offered Securities hereunder and the aggregate principal amount of Offered Securities that such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of Offered Securities, Credit Suisse may make arrangements satisfactory to the Partnership for the purchase of such Offered Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date, the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder, to purchase the Offered Securities that such defaulting Underwriters agreed but failed to purchase. If any Underwriter or Underwriters 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 and arrangements satisfactory to Credit Suisse 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 Underwriter or the Partnership, except as provided in Section 10. As used in this Agreement, the term “Underwriter” includes any person substituted for a Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

     10.  Survival of Certain Representations and Obligations. The respective indemnities, agreements, representations, warranties and other statements of the Partnership or its officers and of the several Underwriters 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 Underwriter, the Partnership or any of its 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 9 or if for any reason the purchase of the Offered Securities by the Underwriters is not consummated, the Partnership shall remain responsible for the expenses to be paid or reimbursed by it pursuant to Section 5 and the respective obligations of the Partnership and the Underwriters pursuant to Section 8 shall remain in effect. If the purchase of the Offered Securities by the Underwriters is not consummated for any reason other than solely because of the termination of this Agreement pursuant to Section 9 or the occurrence of any event specified in clause (iii), (iv), (vi), (vii) or (viii) of Section 7(c), the Partnership will reimburse the Underwriters 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.

     11.  Notices. All communications hereunder will be in writing and, if sent to the Underwriters will be mailed, delivered or telegraphed and confirmed to the Underwriters, c/o Credit Suisse Securities (USA) LLC, Eleven Madison Avenue, New York, N.Y. 10010-3629, Attention: LCD-IBD, or, if sent to the Partnership will be mailed, delivered or telegraphed and confirmed to it at 3738 Oak Lawn Avenue, Dallas, Texas 75219, Attention: John W. McReynolds, President and Chief Financial Officer; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered or telegraphed and confirmed to such Underwriter.

     12.  Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the other persons referred to in Section 8, and no other person will have any right or obligation hereunder.

     13.  Representation of Underwriters. The Representatives will act for the several Underwriters in connection with this purchase, and any action under this Agreement taken by you jointly will be binding upon all the Underwriters.

     14.  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.

     15.  Absence of Fiduciary Relationship. The Partnership acknowledges and agrees that:

     (a)  No Other Relationship . The Underwriters have been retained solely to act as underwriters in connection with the sale of the Offered Securities and that no fiduciary, advisory or agency relationship between the Partnership and the Underwriters has been created in respect of any of the transactions contemplated by this Agreement or the Preliminary or the Final Prospectus, irrespective of whether the Underwriters have advised or are advising the Partnership on other matters;

     (b)  Arm’s-Length Negotiations . The price of the Offered Securities set forth in this Agreement was established by the Partnership following discussions and arms-length negotiations with the Representatives and of the Partnership is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement;

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

     (d)  Waiver . The Partnership waives, to the fullest extent permitted by law, any claims it may have against the Underwriters for breach of fiduciary duty or alleged breach of fiduciary duty and agrees that the Underwriters shall have no liability (whether direct or indirect) to the Partnership 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, including equityholders, employees or creditors of the Partnership.

     16.  Applicable Law. This Agreement shall be governed by, and construed in accordance with, the laws of the State of New York.

     The Partnership 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. The Partnership 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.
