1.Representations and Warranties. The Partnership represents and warrants to, and agrees with, the Underwriter as set forth below in this Section 1.

(a)    The Partnership meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission an automatic shelf registration statement, as defined in Rule 405, on Form S-3 (No. 333-171697), including a related Base Prospectus, for registration under the Act of the offering and sale of the Securities. Such Registration Statement, including any amendments thereto filed prior to the Execution Time, became effective upon filing. The Partnership may have filed with the Commission, as part of an amendment to the Registration Statement or pursuant to Rule 424(b), one or more preliminary prospectus supplements relating to the Securities, each of which has previously been furnished to the Underwriter. The Partnership will file with the Commission a final prospectus supplement relating to the Securities in accordance with Rule 424(b). As filed, such final prospectus supplement shall contain all information required by the Act and the rules thereunder, and, except to the extent the Underwriter shall agree in writing to a modification, shall be in all substantive respects in the form furnished to the Underwriter prior to the Execution Time or, to the extent not completed at the Execution Time, shall contain only such specific additional information and other changes (beyond that contained in the Base Prospectus and any Preliminary Prospectus) as the Partnership has advised the Underwriter, prior to the Execution Time, will be included or made therein. The Registration Statement, at the Execution Time, meets the requirements set forth in Rule 415(a)(1)(x). The initial Effective Date of the Registration Statement was not earlier than the date three years before the Execution Time.

(b)    On each Effective Date, the Registration Statement did, and when the Final Prospectus is first filed in accordance with Rule 424(b) and on the Closing Date (as defined herein) and on any date on which Option Securities are purchased, if such date is not the Closing Date (a “settlement date”), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder; on each Effective Date and at the Execution Time, the Registration Statement did not and will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b) and on the Closing Date and any settlement date, the Final Prospectus (together with any supplement thereto) will not include any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Partnership makes no representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of the Underwriter specifically for inclusion in the Registration Statement or the Final Prospectus (or any supplement thereto), it being understood and agreed that the only such information furnished by or on behalf of the Underwriter consists of the information described as such in Section 8 hereof.

(c)    The Disclosure Package and the price to the public, the number of Underwritten Securities and the number of Option Securities to be included on the cover page of the Final Prospectus, when taken together as a whole, does not contain any untrue statement of a material fact or omit 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. The preceding sentence does not apply to statements in or omissions from the Disclosure Package made in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of the Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriter consists of the information described as such in Section 8 hereof.

(d)    (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Sections 13 or 15(d) of the Exchange Act or form of prospectus), and (iii) at the Execution Time (with such date being used as the determination date for purposes of this clause (iii)), the Partnership was or is (as the case may be) a Well-Known Seasoned Issuer as defined in Rule 405. The Partnership agrees to pay the fees required by the Commission relating to the Securities within the time required by Rule 456(b)(1) without regard to the proviso therein and otherwise in accordance with Rules 456(b) and 457(r).

(e)    (i) At the earliest time after the filing of the Registration Statement that the Partnership or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2)) of the Securities and (ii) as of the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), the Partnership was not and is not an “ineligible issuer” (as defined in Rule 405), without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Partnership be considered an ineligible issuer.

(f)    The Partnership has not received from the Commission any notice pursuant to Rule 401(g)(2) objecting to use of the automatic shelf registration statement form. If at any time when Securities remain unsold by the Underwriter the Partnership receives from the Commission a notice pursuant to Rule 401(g)(2) or otherwise ceases to be eligible to use the automatic shelf registration statement form, the Partnership will (i) promptly notify the Underwriter, (ii) promptly file a new registration statement or post-effective amendment on the proper form relating to the Securities, in a form satisfactory to the Underwriter, (iii) use its best efforts to cause such registration statement or post-effective amendment to be declared effective as soon as practicable, and (iv) promptly notify the Underwriter of such effectiveness. The Partnership will take all other action necessary or appropriate to permit the public offering and sale of the Securities to continue as contemplated in the registration statement that was the subject of the Rule 401(g)(2) notice or for which the Partnership has otherwise become ineligible. References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

(g)    Each Issuer Free Writing Prospectus does not include any information that conflicts with the information contained in the Registration Statement, including any document incorporated therein by reference and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Partnership by or on behalf of the Underwriter specifically for inclusion therein, it being understood and agreed that the only such information furnished by or on behalf of the Underwriter consists of the information described as such in Section 8 hereof. If at any time following issuance of an Issuer Free Writing Prospectus there occurred or occurs an event or development as a result of which such Issuer Free Writing Prospectus conflicted or would conflict with the information then contained in the Registration Statement or as a result of which such Issuer Free Writing Prospectus, if republished immediately following such event or development, would include an untrue statement of a material fact or omitted or would omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, (i) the Partnership has promptly notified or will promptly notify the Underwriter and (ii) the Partnership has promptly amended or will promptly amend or supplement such Issuer Free Writing Prospectus to eliminate or correct such conflict, untrue statement or omission.

(h)    At the Execution Time, the Partnership has an authorized and outstanding equity capitalization as set forth in the sections of the Preliminary Prospectus entitled “Capitalization” (and any similar sections or information, if any, contained in any Issuer Free Writing Prospectus), and, as of the Closing Date and any settlement date, as the case may be, the Partnership shall have an authorized and outstanding equity capitalization as set forth in the sections of the Registration Statement, the Base Prospectus, the Preliminary Prospectus and the Final Prospectus entitled “Capitalization” and “Description of Units” (and any similar sections or information, if any, contained in any Issuer Free Writing Prospectus) (subject, in each case, to the issuance of Units upon exercise of unit options and warrants disclosed as outstanding in the Registration Statement (excluding the exhibits thereto), the Base Prospectus, the Preliminary Prospectus, and the Final Prospectus, the grant of options or other equity awards under existing unit option plans described in the Registration Statement (excluding the exhibits thereto), the Base Prospectus, the Preliminary Prospectus and the Final Prospectus and the issuance of Units (i) upon exercise of the Underwriter’s option to purchase additional Units and (ii) pursuant to an at-the-market or continuous equity offering or any equity distribution agreement relating thereto); all of the issued and outstanding general partner interests, incentive distribution rights and limited partner interests of the Partnership have been duly authorized and validly issued and are fully paid (to the extent required under the Second Amended and Restated Agreement of Limited Partnership of the Partnership (as amended, the “Partnership Agreement”)) and non-assessable (except as such non-assessability may be affected by (i) matters described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus and (ii) Sections 17-303(a), 17-607 or 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”)), have been issued in compliance with all applicable securities laws and were not

(ee)    Neither the Partnership nor any Subsidiary is, and at no time during which a prospectus is required by the Act to be delivered (whether physically or through compliance with Rule 172 under the Act or any similar rule) in connection with any sale of Units will any of them be, and, after giving effect to the offering and sale of the Securities, none of them will be, an “investment company” or an entity “controlled” by an “investment company,” as such terms are defined in the Investment Company Act of 1940, as amended.

(ff)    The Partnership and each of the Subsidiaries have good and marketable title to all real property and good title to all personal property described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any, as being owned by it, free and clear of all Liens except (i) as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any, and (ii) as do not materially interfere with the use of such properties, taken as a whole, as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any, including Liens pursuant to mortgage and/or security agreements given as security for certain non-compete agreements with the prior owners of certain businesses previously acquired by the Partnership and the Subsidiaries; provided, that, with respect to title to pipeline rights-of-way, the Partnership represents only that (A) each applicable Subsidiary has sufficient title to enable it to use and occupy the pipeline rights-of-way as they have been used and occupied in the past and are to be used and occupied in the future as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any, and (B) any lack of title to the pipeline rights-of-way will not have a Material Adverse Effect. All of the real property and buildings held under lease by the Partnership and each Subsidiary are held under valid and subsisting and enforceable leases, with such exceptions as would not materially interfere with the use of such properties, taken as a whole, as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any.

(gg)    The Partnership and each of the Subsidiaries own or possess adequate rights to use all material patents, patent applications, trademarks, service marks, trade names, trademark registrations, service mark registrations, copyrights, licenses and know-how (including trade secrets and other unpatented and/or unpatentable proprietary or confidential information, systems or procedures) necessary for the conduct of their respective businesses; and the conduct of their respective businesses will not conflict in any material sense with,

and neither the Partnership nor any Subsidiary has received any notice of conflict with, any such rights of others.

(hh)    No labor disputes with the employees that are engaged in the businesses of the Partnership and the Subsidiaries exist or, to the knowledge of the Partnership, are imminent or threatened except for those that would not, individually or in the aggregate, have a Material Adverse Effect. To the Partnership’s knowledge after due inquiry, there has been no violation of any federal, state, local or foreign law relating to discrimination in the hiring, promotion or pay of employees, any applicable wage or hour laws or any provision of the Employee Retirement Income Security Act of 1974 or the rules and regulations promulgated thereunder concerning the employees providing services to the Partnership or any Subsidiary.

(ii)    Except as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus and the Final Prospectus, the Partnership and the Subsidiaries (i) are in compliance with any and all applicable laws and regulations relating to the protection of human health and safety, the environment or hazardous or toxic substances or wastes, pollutants or contaminants (“Environmental Laws”), (ii) have received and are in compliance with all permits, licenses or other approvals required of them under applicable Environmental Laws to conduct their respective businesses as they are currently being conducted and (iii) have not received written notice of any, and to the knowledge of the Partnership after due inquiry there are no, pending events or circumstances that could reasonably be expected to form the basis for any actual or potential liability for the investigation or remediation of any disposal or release of hazardous or toxic substances or wastes, pollutants or contaminants, and (iv) are not subject to any pending or, to the knowledge of the Partnership after due inquiry, threatened actions, suits, demands, orders or proceedings relating to any Environmental Laws against the ETP Entities (collectively, “Proceedings”), except where such non-compliance with Environmental Laws, failure to receive required permits, licenses or other approvals, actual or potential liability or Proceedings could not, individually or in the aggregate, be reasonably expected to have a Material Adverse Effect. Except as set forth in the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Final Prospectus and except for the Newmark Groundwater Contamination Superfund site (as to which an affiliate of the Partnership received a request for information under Section 104(e) of the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, as amended (“CERCLA”) in May 2001), none of the ETP Entities nor any of the Subsidiaries is currently named as a “potentially responsible party” under CERCLA.

(jj)    All tax returns required to be filed by the Partnership and the Subsidiaries through the date hereof have been timely filed (or extensions have been timely obtained with respect to such tax returns), and all taxes and other assessments of a similar nature (whether imposed directly or through withholding) including any interest, additions to tax or penalties applicable thereto due or claimed to be due from such entities have been timely paid, other than those being contested in good faith and for which adequate reserves have been provided.

(kk)    The Partnership and each of the Subsidiaries maintain insurance covering their properties, operations, personnel and businesses as they reasonably deem adequate; such insurance insures against such losses and risks to an extent that is adequate in accordance with customary industry practice to protect the Partnership and each of the Subsidiaries and their business; all such insurance is fully in force on the date hereof and will be fully in force at the time of purchase and any additional time of purchase; the Partnership does not have reason to believe that it or any Subsidiary will not be able to renew any such insurance as and when such insurance expires.

(ll)    Neither the Partnership nor any Subsidiary has sustained since the date of the last audited financial statements included in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus or the Issuer Free Writing Prospectuses, if any, any material loss or interference with its respective business from fire, explosion, flood or other calamity, whether or not covered by insurance, or from any labor dispute or court or governmental action, order or decree.

(mm)    Except as described in the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Final Prospectus, none of the ETP Entities or any of the Subsidiaries has sent or received any communication regarding termination of, or intent not to renew, any of the contracts or agreements filed as an exhibit to the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus or the Issuer Free Writing Prospectuses, if any, and no such termination or non-renewal has been threatened by any of the ETP Entities or any Subsidiary. To the knowledge of the Partnership after due inquiry, no third party to any indenture, contract, lease, mortgage, deed of trust, note agreement, loan agreement or other agreement, obligation, condition, covenant or instrument to which any of the ETP Entities or any of the Subsidiaries is a party or bound or to which their respective properties are subject, is in breach, default or violation under any such agreement (and no event has occurred that, with notice or lapse of time or both, would constitute such an event), except for any such breach, default or violation that would not, individually or in the aggregate, have a Material Adverse Effect.

(nn)    The Partnership maintains a system of internal accounting controls sufficient to provide reasonable assurance that (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary to permit preparation of financial statements in conformity with generally accepted accounting principles and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; (iv) the recorded accountability for assets is compared with existing assets at reasonable intervals and appropriate action is taken with respect to any differences; and (v) the interactive data in XBRL incorporated by reference in the Registration Statement, the Base Prospectus, the Preliminary Prospectus and the Final Prospectus fairly presents the information called for in all material respects and is prepared in accordance with the Commission’s rules and guidelines applicable thereto.

(oo)    The Partnership has established and maintains and evaluates “disclosure controls and procedures” (as such term is defined in Rule 13a-15 and 15d-15 under the Exchange Act) and “internal control over financial reporting” (as such term is defined in Rule 13a-15 and 15d-15 under the Exchange Act); such disclosure controls and procedures are designed to ensure that material information relating to the Partnership (including the Subsidiaries) is made known to the Chief Executive Officer and the Chief Financial Officer of ETP LLC, and such disclosure controls and procedures are effective to perform the functions for which they were established; the Partnership’s auditors and the Audit Committee of the Board of Directors of ETP LLC have been advised of: (i) all significant deficiencies, if any, in the design or operation of internal controls that could adversely affect the Partnership’s ability to record, process, summarize and report financial data; (ii) all fraud, if any, whether or not material, that involves management or other employees who have a role in the Partnership’s internal controls; and (iii) all material weaknesses, if any, in internal controls that have been identified for the Partnership’s auditors; since the date of the most recent evaluation of such disclosure controls and procedures and internal controls, there have been no significant changes in internal controls or in other factors that could significantly affect internal controls, including any corrective actions with regard to significant deficiencies and material weaknesses; the principal executive officers (or their equivalents) and principal financial officers (or their equivalents) of the Partnership have made all certifications required by the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”) and any related rules and regulations promulgated by the Commission, and the statements contained in any such certification are complete and correct; the Partnership, the Subsidiaries and the directors and officers of ETP LLC, in their capacity as such, are each in compliance in all material respects with all applicable effective provisions of the Sarbanes-Oxley Act and the rules and regulations of the Commission and the NYSE promulgated thereunder; and the Partnership has taken all necessary actions to ensure that, upon and at all times after effectiveness of the Registration Statement, the Partnership, the Subsidiaries and the officers and directors of ETP LLC, in their capacities as such, will be in compliance in all material respects with the provisions of the Sarbanes-Oxley Act and the rules and regulations promulgated thereunder.

(pp)    On or after July 30, 2002, none of the ETP Entities has directly or indirectly, including through any Subsidiary: (i) extended credit, arranged to extend credit, or renewed any extension of credit, in the form of a personal loan, to or for any director or executive officer of ETP LLC, or to or for any family member or affiliate of any director or executive officer of ETP LLC; or (ii) made any material modification, including any renewal thereof, to the term of any personal loan to any director or executive officer of ETP LLC, or any family member or affiliate of any director or executive officer, which loan was outstanding on July 30, 2002.

(qq)    Each “forward-looking statement” contained or incorporated by reference in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus or the Issuer Free Writing Prospectuses, if any, has been made or reaffirmed with a reasonable basis and in good faith.

(rr)    All statistical or market-related data included or incorporated by reference in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and the Issuer Free Writing Prospectuses, if any, are based on or derived from sources that the Partnership believes to be reliable and accurate in all material respects, and the Partnership has obtained the written consent to the use of such data from such sources to the extent required.

(ss)    Neither the Partnership nor any Subsidiary is currently prohibited, directly or indirectly, from making distributions in respect of its equity securities, except in each case as described in (i) the Registration Statement, the Base Prospectus, the Preliminary Prospectus or the Final Prospectus or (ii) the organizational documents of the Partnership and the Subsidiaries.

(tt)    Immediately after the issuance and sale of the Securities as contemplated hereby, no preferred securities of the Partnership shall be issued or outstanding; and the issuance and sale of the Securities as contemplated hereby will not cause any holder of Units, securities convertible into or exchangeable or exercisable for Units, or options, warrants or other rights to purchase Units or any other securities of the Partnership to have any right to acquire any preferred securities of the Partnership.

(uu)    The Partnership is in compliance with the rules of the NYSE, including, without limitation, the requirements for initial and continued listing of the Securities on the NYSE.

(vv)    Except pursuant to this Agreement, none of the ETP Entities or the Subsidiaries has incurred any liability for any finder’s or broker’s fees or agent’s commissions in connection with the execution and delivery of this Agreement or the consummation of the transactions contemplated by this Agreement.

(ww)    None of the ETP Entities nor any of their respective Affiliates (as such term in defined in Rule 405 promulgated under the Act) has taken, directly or indirectly, any action designed, or that has constituted or could reasonably be expected to cause or result in, under the Exchange Act or otherwise, the stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Securities.

(xx)    To the knowledge of the Partnership after due inquiry, there are no affiliations or associations between (i) any member of the FINRA and (ii) the Partnership, any of ETP LLC’s officers or directors, any 5% or greater securityholders of the Partnership, or any beneficial owner of the Partnership’s unregistered equity securities that were acquired at any time on or after the 180th day immediately preceding the date the Registration Statement was initially filed with the Commission, except as disclosed in the Registration Statement (excluding the exhibits thereto), the Base Prospectus, the Preliminary Prospectus and the Final Prospectus.

(yy)    The Partnership has not distributed and will not distribute, prior to the later to occur of (i) the time of purchase and additional time of purchase and (ii) the completion

of the distribution of the Securities, any prospectus (as defined under the Act) in connection with the offering and sale of the Securities other than the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Issuer Free Writing Prospectuses, if any, or other materials, if any, permitted by the Act, including Rule 134 promulgated thereunder.

(zz)    The operations of the ETP Entities and the Subsidiaries are and have been conducted at all times in compliance with applicable financial recordkeeping and reporting requirements and the money laundering statutes and rules and regulations thereunder and any related or similar rules, regulations or guidelines issued, administered or enforced by any governmental agency (collectively, the “Money Laundering Laws”), and no action, suit or proceeding by or before any court or governmental agency, authority or body or any arbitrator involving any of the ETP Entities or any of the Subsidiaries with respect to the Money Laundering Laws is pending or, to the best knowledge of the Partnership, threatened.

([[)    None of the ETP Entities or any Subsidiary nor, to the knowledge of the Partnership, any director, officer, agent, employee or affiliate of any of the ETP Entities or any Subsidiary is aware of or has taken any action, directly or indirectly, that would result in a violation by such persons of the Foreign Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined in the FCPA) or any foreign political party or official thereof or any candidate for foreign political office, in contravention of the FCPA; and the ETP Entities, the Subsidiaries and, to the knowledge of the Partnership, their affiliates have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith.

(aaa)    None of the ETP Entities or any Subsidiary, nor to the knowledge of the Partnership, any director, officer, agent, employee or affiliate of any ETP Entity or any Subsidiary, is currently subject to any sanctions administered by the Office of Foreign Assets Control of the U.S. Treasury Department (“OFAC”); and the Partnership will not directly or indirectly use the proceeds of the sale of the Securities, or lend, contribute or otherwise make available such proceeds to any subsidiary, joint venture partner or other person or entity, for the purpose of financing the activities of any person currently subject to any U.S. sanctions administered by OFAC.

Any certificate signed by any officer of ETP LLC and delivered to the Underwriter or counsel for the Underwriter in connection with the offering of the Securities shall be deemed a representation and warranty by the Partnership, as to matters covered thereby, to the Underwriter.

2.    Purchase and Sale.

(a)    Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to sell to the Underwriter, and the

Underwriter agrees to purchase the Underwritten Securities from the Partnership, at the purchase price set forth in Schedule I hereto.

(b)    Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership hereby grants an option to the Underwriter to purchase up to the number of Option Securities set forth in Schedule I hereto at the same purchase price per share as the Underwriter shall pay for the Underwritten Securities. Said option may be exercised in whole or in part at any time on or before the 30th day after the date of the Final Prospectus upon written or telegraphic notice by the Underwriter to the Partnership setting forth the number of Option Securities as to which the Underwriter is exercising the option and the settlement date.

3.    Delivery and Payment. Delivery of and payment for the Underwritten Securities and the Option Securities (if the option provided for in Section 2(b) hereof shall have been exercised on or before the third Business Day immediately preceding the Closing Date) shall be made on the date and at the time specified in Schedule I hereto or at such time on such later date not more than four Business Days after the foregoing date as the Underwriter shall designate, which date and time may be postponed by agreement between the Underwriter and the Partnership (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). The date and time at which such delivery and payment are to be made is sometimes referred to herein as the “time of purchase.” Delivery of the Securities shall be made to the Underwriter against payment by the Underwriter of the purchase price thereof to or upon the order of the Partnership by wire transfer payable in same-day funds to an account specified by the Partnership. Delivery of the Underwritten Securities and the Option Securities shall be made through the facilities of The Depository Trust Company unless the Underwriter shall otherwise instruct.

If the option provided for in Section 2(b) hereof is exercised after the third Business Day immediately preceding the Closing Date, the Partnership will deliver the Option Securities (at the expense of the Partnership) to the Underwriter, on the date specified by the Underwriter (which shall be within three Business Days after exercise of said option) (any such date being sometimes referred to herein as an “additional time of purchase”) against payment by the Underwriter of the purchase price thereof to or upon the order of the Partnership by wire transfer payable in same-day funds to an account specified by the Partnership. If settlement for the Option Securities occurs after the Closing Date, the Partnership will deliver to the Underwriter on the settlement date for the Option Securities, and the obligation of the Underwriter to purchase the Option Securities shall be conditioned upon receipt of, supplemental opinions, certificates and letters confirming as of such date the opinions, certificates and letters delivered on the Closing Date pursuant to Section 6 hereof.

4.    Offering by Underwriter. It is understood that the Underwriter proposes to offer the Securities for sale to the public as set forth in the Final Prospectus.

5.    Agreements. The Partnership agrees with the Underwriter that:

(a)    Prior to the termination of the offering of the Securities, the Partnership will not file any amendment of the Registration Statement or supplement (including the Final Prospectus or any Preliminary Prospectus) to their Base Prospectus unless the Partnership

has furnished the Underwriter a copy for your review prior to filing and will not file any such proposed amendment or supplement to which the Underwriter reasonably objects. The Partnership will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Underwriter with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to the Underwriter of such timely filing. The Partnership will promptly advise the Underwriter (i) when the Final Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of the offering of the Securities, any amendment to the Registration Statement shall have been filed or become effective, (iii) prior to termination of the offering of the Securities, of any request by the Commission or its staff for any amendment of the Registration Statement, or any Rule 462(b) Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) prior to termination of the offering of the Securities, of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Securities for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b)    If, at any time prior to the filing of the Final Prospectus pursuant to Rule 424(b), any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Partnership will: (i) notify promptly the Underwriter so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Underwriter in such quantities as they may reasonably request.

(c)    If, at any time when a prospectus relating to the Securities is required to be delivered under the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), any event occurs as a result of which the Final Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Final Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Final Prospectus, the Partnership promptly will (i)

notify the Underwriter of any such event, (ii) prepare and file with the Commission, subject to the second sentence of paragraph (a) of this Section 5, an amendment or supplement or new registration statement that will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Final Prospectus and (iv) supply any supplemented Final Prospectus to the Underwriter in such quantities as they may reasonably request. Neither the Underwriter’s consent to nor the Underwriter’s delivery of any such amendment or supplement shall constitute a waiver of any of the conditions set forth in Section 6 hereof.

(d)    As soon as practicable, but not later than 16 months after the date of this Agreement, the Partnership will make generally available to its security holders and to the Underwriter an earnings statement or statements of the Partnership and the Subsidiaries that will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(e)    The Partnership will furnish to the Underwriter and counsel for the Underwriter, without charge, signed copies of the Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by the Underwriter or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus and any supplement thereto as the Underwriter may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(f)    The Partnership will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Underwriter may designate and will maintain such qualifications in effect so long as required for the distribution of the Securities; provided that in no event shall the Partnership be obligated to qualify to do business in any jurisdiction where it is not now so qualified or to take any action that would subject it to service of process in suits, other than those arising out of the offering or sale of the Securities, in any jurisdiction where it is not now so subject.

(g)    The Partnership agrees that, unless it has or shall have obtained the prior written consent of the Underwriter, and the Underwriter agrees with the Partnership that, unless it has or shall have obtained, as the case may be, the prior written consent of the Partnership, it has not made and will not make any offer relating to the 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 by the Partnership with the Commission or retained by the Partnership under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule III hereto and any electronic road show. Any such free writing prospectus consented to by the Underwriter or the Partnership is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be,

with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(h)    The Partnership will not, without the prior written consent of the Underwriter, offer, sell, contract to sell, pledge, or otherwise dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership or any affiliate of the Partnership or any person in privity with the Partnership or any affiliate of the Partnership, directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any other Units or any securities convertible into, or exercisable or exchangeable for, Units; or publicly announce an intention to effect any such transaction, until the Business Day set forth on Schedule I hereto (the "Lock-up Period"), provided, however, that the Partnership may (i) issue and sell Units upon the exercise of options or warrants, or the conversion of other securities, disclosed as outstanding as of the Execution Time and may issue or register restricted units, employee options or other equity awards not exercisable during the Lock-up Period pursuant to the Amended and Restated 2004 Unit Plan described in the Registration Statement (excluding the exhibits thereto), the Base Prospectus, the Preliminary Prospectus and the Final Prospectus, (ii) issue or register restricted units, employee options or other equity awards not exercisable during the Lock-up Period pursuant to the Amended and Restated 2004 Unit Plan or the 2008 Long-Term Incentive Plan described in the Partnership’s definitive proxy statement filed with the Commission on November 21, 2008, (iii) issue and sell Units pursuant to the Partnership’s distribution reinvestment program; (iv) file a registration statement relating to, and issue and sell Units pursuant to, an at-the-market or continuous equity offering or any equity distribution agreement relating thereto; and (v) issue up to 49,484,102 Units to ETE in connection with the Contribution Agreement.

(i)    The Partnership will not take, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, under the Exchange Act or otherwise, stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Securities.

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

(k)    The Partnership agrees to pay the costs and expenses relating to the following matters: (i) the preparation, printing or reproduction and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and

each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, each Preliminary Prospectus, the Final Prospectus and each Issuer Free Writing Prospectus, and all amendments or supplements to any of them, as may, in each case, be reasonably requested for use in connection with the offering and sale of the Securities; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Securities, including any stamp or transfer taxes in connection with the original issuance and sale of the Securities; (iv) the printing (or reproduction) and delivery of this Agreement, any blue sky memorandum and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Securities; (v) the registration of the Securities under the Exchange Act and the listing of the Securities on the NYSE; (vi) any registration or qualification of the Securities for offer and sale under the securities or blue sky laws of the several states (including filing fees and the reasonable fees and expenses of counsel for the Underwriter relating to such registration and qualification); (vii) any filings required to be made with the FINRA (including filing fees and the reasonable fees and expenses of counsel for the Underwriters relating to such filings); (viii) the transportation and other expenses incurred by or on behalf of Partnership representatives in connection with presentations to prospective purchasers of the Securities; (ix) the fees and expenses of the Partnership’s accountants and the fees and expenses of counsel (including local and special counsel) for the Partnership; and (x) all other costs and expenses incident to the performance by the Partnership of its obligations hereunder.

(iii)    since the date of the most recent financial statements included in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto), there has been no Material Adverse Effect, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any supplement thereto).

(f)    The Partnership shall have requested and caused Grant Thornton LLP to have furnished to the Underwriter, at the Execution Time and at the Closing Date or any settlement date, as the case may be, letters addressed (which may refer to letters previously delivered to the Underwriter), dated respectively as of the Execution Time and as of the Closing Date or any settlement date, as the case may be, in form and substance satisfactory to the

Underwriter, which letters shall, (i) confirm that they are independent public accountants within the meaning of the 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) state, as of the date of such letters (or, with respect to matters involving changes or developments since the respective dates as of which specified financial information is given in the Disclosure Package and the Final Prospectus, as of a date not more than five days prior to the date of such letters), 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.

(h)    Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Partnership’s or its Subsidiaries’ debt securities by any “nationally recognized statistical rating organization” (as defined in Section 3(a)(62) of the Exchange Act) or any notice given of any intended or potential decrease in any such rating or of a possible change in any such rating that does not indicate the direction of the possible change.

(i)    The Partnership shall have furnished to the Underwriter such other documents and certificates as to the accuracy and completeness of any statement in the Registration Statement, the Base Prospectus, the Preliminary Prospectus, the Final Prospectus and any Issuer Free Writing Prospectus as of the time of purchase and, if applicable, the additional time of purchase, as the Underwriter may reasonably request.

(j)    The Securities shall have been listed and admitted and authorized for trading on the NYSE, and satisfactory evidence of such actions shall have been provided to the Underwriter.

(k)    At the Execution Time, the Partnership shall have furnished to the Underwriter each of the signed Lock-Up Agreements referred to in Section 1(dd) hereof, and each such Lock-Up Agreement shall be in full force and effect at the Execution Time, the Closing Date and the settlement date, as the case may be.

Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.

7.    Reimbursement of Underwriter’s Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriter set forth in Section 6 hereof is not satisfied, because of any termination pursuant to Section 9 hereof or because of any refusal, inability or failure on the part of the Partnership to perform any agreement herein or comply with any provision hereof other than by reason of a default by any of the Underwriter, the Partnership will reimburse the Underwriter on demand for all out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by them in connection with the proposed purchase and sale of the Securities.

8.    Indemnification and Contribution.

(a)    The Partnership agrees to indemnify and hold harmless the Underwriter, the directors, officers, employees and agents of the Underwriter, affiliates of the Underwriter who have, or who are alleged to have, participated in the distribution of the Units as underwriters, and each person who controls the Underwriter within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages or liabilities, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or other Federal or state statutory law or regulation, at common law 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 a material fact contained in the registration statement for the registration of the Securities as originally filed or in any amendment thereof, or in the Base Prospectus, any Preliminary Prospectus or any other preliminary prospectus supplement relating to the Securities, the Final Prospectus, any Issuer Free Writing Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Underwriter specifically for inclusion therein. This

indemnity agreement will be in addition to any liability which the Partnership may otherwise have.

(b)    The Underwriter agrees to indemnify and hold harmless the Partnership, each of its directors, each of its officers who signs the Registration Statement, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Partnership to the Underwriter, but only with reference to written information relating to the Underwriter furnished to the Partnership by or on behalf of the Underwriter specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriter may otherwise have. The Partnership acknowledges that the statements set forth (i) in the last paragraph of the cover page regarding delivery of the Securities and, under the heading “Underwriting” or “Plan of Distribution,” (ii) the name of Underwriter and its participation in the sale of the Securities, (iii) the sentence related to the selling concession and (iv) the paragraph related to stabilization, and covering transactions in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus constitute the only information furnished in writing by or on behalf of the Underwriter for inclusion in any Preliminary Prospectus, the Final Prospectus or any Issuer Free Writing Prospectus.

(c)    Promptly after receipt by an indemnified party under this Section 8 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 this Section 8, notify the indemnifying party in writing of the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the fees and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel satisfactory to the indemnified party to represent the indemnified party within a reasonable

time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, 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 (i) includes an unconditional release of the indemnified party from all liability arising out of such action, suit, 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)    In the event that the indemnity provided in paragraph (a), (b) or (c) of this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, each of the Partnership and the Underwriter agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending the same) (collectively “Losses”) to which the Partnership and the Underwriter may be subject in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and by the Underwriter on the other from the offering of the Securities; provided, however, that in no case shall the Underwriter (except as may be provided in any agreement among underwriters relating to the offering of the Securities) be responsible for any amount in excess of the underwriting discount or commission applicable to the Securities purchased by the Underwriter hereunder. If the allocation provided by the immediately preceding sentence is unavailable for any reason, each of the Partnership and the Underwriter shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Partnership on the one hand and of the Underwriter on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Partnership shall be deemed to be equal to the total net proceeds from the offering (before deducting expenses) received by it, and benefits received by the Underwriter shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Final Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Partnership on the one hand or the Underwriter on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Partnership and the Underwriter agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls the Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of the Underwriter shall have the same rights to contribution as the Underwriter, and each person

who controls the Partnership within the meaning of either the Act or the Exchange Act, each officer of the Partnership who shall have signed the Registration Statement and each director of the Partnership shall have the same rights to contribution as the Partnership, subject in each case to the applicable terms and conditions of this paragraph (d).

9.    Termination. This Agreement shall be subject to termination in the absolute discretion of the Underwriter, by notice given to the Partnership prior to delivery of and payment for the Securities, if at any time prior to such delivery and payment (i) trading in the Partnership’s Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities, or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis, the effect of which is such as to make it, in the sole judgment of the Underwriter, impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by any Preliminary Prospectus or the Final Prospectus (exclusive of any amendment or supplement thereto).

10.    Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership or the officers of ETP LLC and of the Underwriter set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of the Underwriter or the Partnership or any of the officers, directors, employees, agents or controlling persons referred to in Section 8 hereof, and will survive delivery of and payment for the Securities. The provisions of Sections 7 and 8 hereof shall survive the termination or cancellation of this Agreement.

11.    Notices. All communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriter, will be mailed, delivered or telefaxed to Barclays Capital Inc., Attention: Syndicate Registration (Facsimile No. (646) 834-8133), 745 Seventh Avenue, New York, New York 10019; or, if sent to the Partnership, will be mailed, delivered or telefaxed to it at Energy Transfer Partners, L.P., 3738 Oak Lawn Avenue, Dallas, Texas 75219, Attention: General Counsel, Facsimile No. (713) 989-1212 and confirmed to it at ###-###-####, attention of the Legal Department.

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

13.    No Fiduciary Duty. The Partnership hereby acknowledges that (a) the purchase and sale of the Securities pursuant to this Agreement is an arm’s-length commercial transaction between the Partnership, on the one hand, and the Underwriter and any affiliate through which it may be acting, on the other, (b) the Underwriter is acting as principal and not as an agent or fiduciary of the Partnership and (c) the Partnership’s engagement of the Underwriter in connection with the offering and the process leading up to the offering is as independent contractors and not in any other capacity. Furthermore, the Partnership agrees that it is solely responsible for making its own judgments in connection with the offering (irrespective of whether the Underwriter has

advised or is currently advising the Partnership on related or other matters). The Partnership agrees that it will not claim that the Underwriter has rendered advisory services of any nature or respect, or owe an agency, fiduciary or similar duty to the Partnership, in connection with such transaction or the process leading thereto.

14.    Integration. This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Partnership and the Underwriter, or any of them, with respect to the subject matter hereof.

15.    Applicable Law. This Agreement will be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within 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.

16.    Waiver of Jury Trial. The Partnership hereby irrevocably waives, to the fullest extent permitted by applicable law, any and all right to trial by jury in any legal proceeding arising out of or relating to this Agreement or the transactions contemplated hereby.

(6)     The equity securities of the Partnership, including the Units, conform in all material respects to the description thereof contained in the Registration Statement, the Preliminary Prospectus and the Prospectus.

(7)    The Registration Statement has become effective under the Act. With your consent, based solely on a telephonic confirmation by a member of the Staff of the Commission on April 10, 2013, such counsel confirmed that no stop order suspending the effectiveness of the Registration Statement has been issued under the Act and no proceedings therefore have been initiated by the Commission.

(11)     The statements included in the Preliminary Prospectus and the Prospectus under the captions “Description of Units” and “Cash Distribution Policy,” insofar as such statements purport to constitute a summary of the terms of the Units are accurate summaries in all material respects.

(13)     The Partnership is not, and immediately after giving effect to the sale of the Units in accordance with the Underwriting Agreement and the application of the proceeds as described in the Time of Sale Prospectus and the Prospectus under the caption “Use of Proceeds,” will not be required to be registered as an “investment company” within the meaning of the Investment Company Act of 1940, as amended.

Based on such counsel’s participation, review and reliance as described above, such counsel advises you that no facts came to such counsel’s attention that caused such counsel to believe that:
