The Securities will be issued under an indenture (the “Base Indenture”) dated as of May 27, 2014, between the Partnership and U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the third supplemental indenture (the “Supplemental Indenture”) to be dated May 10, 2018 (the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). Any reference herein to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3 which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, any Preliminary Prospectus or the Final Prospectus shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Base Prospectus, any Preliminary Prospectus or the Final Prospectus, as the case may be, deemed to be incorporated therein by reference. The term “Enable Entities” shall refer to, collectively, the Partnership, Enable GP, LLC, a Delaware limited liability company and the sole general partner of the Partnership (the “General Partner”), and each of the entities set forth on Schedule V hereto (collectively, the “Operating Subsidiaries”). Certain terms used herein are defined in Section 20 hereof.

1. Representations and Warranties. The Partnership represents and warrants to, and agrees with, each 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 (the file number of which is set forth in Schedule I hereto), on Form S-3, 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, and no stop order suspending the effectiveness of the Registration Statement is in effect, and no proceeding for that purpose or pursuant to Section 8A of the Securities Act against the Partnership or related to the offering of the Securities has been initiated or, to the Partnership’s knowledge, threatened by the Commission. 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 you. 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 Representatives shall agree in writing to a modification, shall be in all substantive respects in the form furnished to you 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 you, 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), the Final Prospectus (and any supplement thereto) will, comply in all material respects with the applicable requirements of the Act, the Exchange Act and the Trust Indenture Act and the respective rules thereunder; on each Effective Date, at the Execution Time and on the Closing Date, 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; on the Effective Date and on the Closing Date the Indenture did or will comply in all material respects with the applicable requirements of the Trust Indenture Act and the rules thereunder; and on the date of any filing pursuant to Rule 424(b) and on the Closing 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 (i) that part of the Registration Statement which shall constitute the Statement of Eligibility and Qualification (Form T-1) under the Trust Indenture Act of the Trustee or (ii) 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 any Underwriter through the Representatives 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 any Underwriter consists of the information described as such in Section 8 hereof.

(c) The Disclosure Package and each electronic road show, when taken together as a whole with the Disclosure Package, do 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 based upon and in conformity with written information furnished to the Partnership by any Underwriter through the Representatives specifically for use therein, it being understood and agreed that the only such information furnished by or on behalf of any 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), (iii) at the time the Partnership or any person acting on its behalf (within the meaning, for this clause only, of Rule 163(c)) made any offer relating to the Securities in reliance on the exemption in Rule 163, and (iv) at the Execution Time (with such date being used as the determination date for purposes of this clause (iv)), 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.

(mm) Except as has been disclosed to the Underwriters or is not material to the analysis under any Sanctions, none of the Enable Entities has engaged in any dealings or transactions with or for the benefit of a Sanctioned Person, or with or in a Sanctioned Country, in the preceding three years, nor do any of the Enable Entities have any plans to increase their dealings or transactions with or for the benefit of Sanctioned Persons, or with or in Sanctioned Countries.

(nn) The Partnership has not taken, directly or indirectly, any action designed to or that would constitute or that might reasonably be expected to cause or result in, stabilization or manipulation of the price of any security of the Partnership to facilitate the sale or resale of the Securities.

(oo) The Partnership has taken all necessary action to ensure that the Partnership and, to the Partnership’s knowledge, the General Partner’s directors and officers, in their capacities as such, are in compliance in all material respects with any applicable provision of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

(pp) At the Closing Date, the Partnership and, to the Partnership’s knowledge, the General Partner’s directors or officers, in their capacities as such, will be in compliance in all material respects with the rules of the New York Stock Exchange (the “NYSE”) that are effective and applicable to the Partnership as of the Closing Date.

(qq) There are no contracts, arrangements or understandings (other than this Agreement) between any Enable Entity and any person that would give rise to a valid claim against any Enable Entity or any Underwriter for a brokerage commission, finder’s fee or other like payment in connection with the offering of the Securities.

(rr) Each of the Enable Entities has such permits, consents, licenses, franchises, certificates and authorizations of governmental or regulatory authorities (“permits”) as are necessary to own its properties and to conduct its business in the manner described in the Disclosure Package and the Final Prospectus, subject to such qualifications as may be set forth in the Disclosure Package and the Final Prospectus, except for such permits that, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; each of the Enable Entities has fulfilled and performed all its material obligations with respect to such permits which are due to have been fulfilled and performed and no event has occurred which allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any impairment of the rights of the holder of any such permit, subject in each case to such qualifications as may be set forth in the Disclosure Package and the Final Prospectus, except for such permits that, if revoked or terminated, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(ss) Each of the Enable Entities has such consents, easements, rights-of-way or licenses from any person (“rights-of-way”) as are necessary to conduct its business in the manner described in the Disclosure Package and the Final Prospectus, subject to such qualifications as may be set forth in the Disclosure Package and the Final Prospectus, except for such rights-of-way that, if not obtained, would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; each of the Enable Entities has fulfilled and performed all its material obligations with respect to such rights-of-way and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or would result in any impairment of the rights of the holder of any such rights-of-way, subject in each case to such qualification as may be set forth in the Disclosure Package and the Final Prospectus, except for such revocation or termination that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect; and except as described in the Disclosure Package and the Final Prospectus, none of such rights-of-way contains any restriction that is materially burdensome to the Enable Entities, taken as a whole.

(tt) Except as disclosed in the Disclosure Package and the Final Prospectus, each of the Enable Entities (i) is in compliance with all applicable federal, state and local laws and regulations relating to the prevention of pollution or protection of human health and safety (to the extent human health and safety relate to exposure to Hazardous Materials, as defined below) and the environment or imposing liability or standards of

conduct concerning any Hazardous Material (collectively, “Environmental Laws”), (ii) has received all permits required of it under applicable Environmental Laws to conduct its business as presently conducted, (iii) is in compliance with all terms and conditions of any such permits, (iv) is not subject to any claim by any governmental agency or government body or person relating to Environmental Laws or Hazardous Materials and (v) to the knowledge of the Enable Parties, does not have any liability in connection with the release into the environment of any Hazardous Material, except where such noncompliance with Environmental Laws, failure to receive required permits, failure to comply with the terms and conditions of such permits and such claims and such liabilities would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The term “Hazardous Material” means (A) any “hazardous substance” as defined in the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, (B) any “hazardous waste” as defined in the Resource Conservation and Recovery Act, as amended, (C) any petroleum or petroleum product, (D) any polychlorinated biphenyl and (E) any pollutant or contaminant or hazardous, dangerous or toxic chemical, material, waste or substance regulated under or within the meaning of any applicable law designed to protect the environment. In the ordinary course of business, each of the Enable Entities periodically reviews the effect of Environmental Laws on its business, operations and properties, in the course of which it identifies and evaluates costs and liabilities that are reasonably likely to be incurred pursuant to such Environmental Laws (including, without limitation, any capital or operating expenditures required for clean-up, closure of properties or compliance with Environmental Laws, or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties). On the basis of such review, each of the Enable Entities has reasonably concluded that, except as disclosed in the Disclosure Package and the Final Prospectus, such associated costs and reasonably foreseeable liabilities relating to the Enable Entities would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

(uu) None of the Enable Entities are aware of any costs or liabilities associated with Environmental Laws (including, without limitation, any capital or operating expenditures required for cleanup, closure of properties or compliance with Environmental Laws or any permit, license or approval, any related constraints on operating activities and any potential liabilities to third parties) which would, individually or in the aggregate, have a Material Adverse Effect.

(vv) Except as otherwise disclosed in the Disclosure Package and the Final Prospectus, the Enable Entities and any “employee benefit plan” (as defined under the Employee Retirement Income Security Act of 1974 (as amended, “ERISA,” which term, as used herein, includes the regulations and published interpretations thereunder)) established or maintained by the Enable Entities or their ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA, and, if applicable, the qualification requirements under Section 401(a) of the Internal Revenue Code of 1986 (as amended, the “Code,” which term, as used herein, includes the regulations and published interpretations thereunder), except where the failure to comply would not have a Material Adverse Effect. “ERISA Affiliate” means, with respect to the Enable Entities, any

member of any group of organizations described in Section 414(b), (c), (m) or (o) of the Code with which the Enable Entities is treated as a single employer. No “reportable event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained as of the date hereof by the Enable Entities or any of their ERISA Affiliates, except for any such occurrence as would not have a Material Adverse Effect. No “employee benefit plan” established or maintained as of the date hereof by the Enable Entities or any of their ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit liabilities” (as defined under ERISA) except for such liabilities as would not have a Material Adverse Effect. With respect to any “employee benefit plan” established, maintained or contributed to as of the date hereof by the Enable Entities or any of their ERISA Affiliates, neither the Enable Entities, nor any of their ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from, any such “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code except for such liability as would not have a Material Adverse Effect.

(ww) Any statistical and market-related data included or incorporated by reference in the Disclosure Package or the Final Prospectus are based on or derived from sources that the Partnership believes to be reliable and accurate.

(xx) The statements made or incorporated by reference in the Disclosure Package and the Final Prospectus under the captions “Description of Certain Other Indebtedness,” “Description of the Notes,” and “Certain U.S. Federal Income Tax Consequences” thereof, insofar as they purport to constitute summaries of United States federal income tax law, rules or regulations or governmental proceedings or legal conclusions with respect thereto, contracts and other documents, descriptions of the Securities, the Indenture, or any other instruments, constitute accurate summaries of the terms of such statutes, rules and regulations, legal and governmental proceedings and contracts and other documents in all material respects.

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

2. Purchase and Sale. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to sell to each Underwriter, and each Underwriter agrees, severally and not jointly, to purchase from the Partnership, at the purchase price set forth in Schedule I hereto the principal amount of the Securities set forth opposite such Underwriter’s name in Schedule II hereto.

3. Delivery and Payment. Delivery of and payment for the Securities 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 three Business Days after the foregoing date as the Representatives shall designate, which date and time may be postponed by agreement between the Representatives and

the Partnership or as provided in Section 9 hereof (such date and time of delivery and payment for the Securities being herein called the “Closing Date”). Delivery of the Securities shall be made to the Representatives for the respective accounts of the several Underwriters against payment by the several Underwriters through Merrill Lynch, Pierce, Fenner & Smith Incorporated 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 Securities shall be made through the facilities of The Depository Trust Company unless the Representatives shall otherwise instruct.

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

5. Agreements. The Partnership agrees with the several Underwriters 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 the Base Prospectus unless the Partnership has furnished you a copy for your review prior to filing and will not file any such proposed amendment or supplement to which you reasonably object. The Partnership will cause the Final Prospectus, properly completed, and any supplement thereto to be filed in a form approved by the Representatives with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will, upon written request, provide evidence satisfactory to the Representatives of such timely filing. The Partnership will promptly advise the Representatives (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) of any request by the Commission or its staff for any amendment of the Registration Statement, or for any supplement to the Final Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or of any notice objecting to its use or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the 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 reasonable best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its reasonable best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) The Partnership will prepare a final term sheet, containing solely a description of final terms of the Securities and the offering thereof, in the form approved by you and attached as Schedule IV hereto and file such term sheet pursuant to Rule 433(d) within the time required by such Rule.

(c) 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 in order to make the statements therein, in the light of the circumstances under which they were made not misleading, the Partnership will (i) notify promptly the Representatives 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 you in such quantities as you may reasonably request.

(d) 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 in order 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 Representatives 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 which will correct such statement or omission or effect such compliance, (iii) use its reasonable 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 you in such quantities as you may reasonably request.

(e) The Partnership will make generally available to its unitholders and to the Representatives an earnings statement or statements of the Partnership and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158.

(f) The Partnership will furnish to the Representatives and counsel for the Underwriters, upon request and without charge, one signed copy of the Registration Statement (including exhibits thereto) and to each other Underwriter a copy of the Registration Statement (without exhibits thereto) and, so long as delivery of a prospectus by an 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 Representatives may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(g) The Partnership will arrange, if necessary, for the qualification of the Securities for sale under the laws of such jurisdictions as the Representatives 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 (i) qualify as a foreign limited partnership in any jurisdiction in which it would not otherwise be required to so qualify, (ii) file a general consent to service of process in any such jurisdiction or (iii) subject itself to taxation in any jurisdiction in which it would not otherwise be subject.

(h) The Partnership agrees that, unless it has or shall have obtained the prior written consent of the Representatives, and each Underwriter, severally and not jointly, 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, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(b) hereto; 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 Representatives 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.

(i) During the period beginning on the date hereof and continuing to and including the Closing Date, the Partnership will not offer, sell, contract to sell or otherwise dispose of any debt securities of or guaranteed by the Partnership that are substantially similar to the Securities or publicly announce an intention to effect any such transaction.

(j) 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.

(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) any registration of the Securities under the Exchange Act; (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 Underwriters relating to such registration and qualification); (vii) the transportation and other expenses incurred by or on behalf of Partnership representatives in connection with presentations to prospective purchasers of the Securities; (viii) 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 (ix) all other costs and expenses incident to the performance by the Partnership of its respective obligations hereunder. Except as provided in this Section 5(k) and in Section 7, the Underwriters shall pay their own expenses, including the fees and disbursements of their counsel, transfer taxes on any resale of the Securities by any Underwriter, any advertising expenses connected with any offers they may make and other expenses incurred by the Underwriters on their own behalf in connection with presentations to prospective purchasers of the Securities.

6. Conditions to the Obligations of the Underwriters. The obligations of the Underwriters to purchase the Securities shall be subject to the accuracy of the representations and warranties on the part of the Partnership contained herein as of the Execution Time and the Closing Date, to the accuracy of the statements of the Partnership made in any certificates pursuant to the provisions hereof, to the performance by the Partnership of its obligations hereunder and to the following additional conditions:

(a) The Final Prospectus, and any supplement thereto, have been filed in the manner and within the time period required by Rule 424(b); the final term sheet contemplated by Section 5(b) hereto, and any other material required to be filed by the Partnership pursuant to Rule 433(d) under the Act, shall have been filed with the Commission within the applicable time periods prescribed for such filings by Rule 433; and no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(b) The Partnership shall have requested and caused Vinson & Elkins L.L.P., counsel for the Partnership, to have furnished to the Representatives its opinion, dated the Closing Date and addressed to the Representatives, substantially in the form attached hereto as Exhibit A.

(c) The Partnership shall have requested and caused the Vice President, Deputy General Counsel, Secretary, and Chief Ethics & Compliance Officer of the General Partner to have furnished to the Representatives his opinion, dated the Closing Date and addressed to the Representatives, substantially in the form attached hereto as Exhibit B.

(d) The Representatives shall have received from Latham & Watkins LLP, counsel for the Underwriters, such opinion or opinions, dated the Closing Date and addressed to the Representatives, with respect to the issuance and sale of the Securities, the Indenture, the Registration Statement, the Disclosure Package, the Final Prospectus (together with any supplement thereto) and other related matters as the Representatives may reasonably require, and the Partnership shall have furnished to such counsel such documents as they reasonably request for the purpose of enabling them to pass upon such matters.

(e) The Partnership shall have furnished to the Representatives a certificate of the General Partner, signed by the Chief Financial Officer of the General Partner, dated the Closing Date, to the effect that the signer of such certificate has carefully examined the Registration Statement, the Disclosure Package, the Final Prospectus and any supplements or amendments thereto, as well as each electronic road show used in connection with the offering of the Securities, and this Agreement and that:

(i) the representations and warranties of the Partnership in this Agreement are true and correct on and as of the Closing Date with the same effect as if made on the Closing Date and the Partnership has complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to the Closing Date;

(ii) no stop order suspending the effectiveness of the Registration Statement or any notice objecting to its use has been issued and no proceedings for that purpose have been instituted or, to the Partnership’s knowledge, threatened; and

(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 Deloitte & Touche LLP, independent public accountants of the Partnership, to have furnished to the Representatives, at the Execution Time and at the Closing Date, letters, (which may refer to letters previously delivered to the Representatives), dated respectively as of the Execution Time and as of the Closing Date, and in the forms reasonably satisfactory to the Representatives, which letters shall cover, without limitation, the various financial disclosures contained in or incorporated by reference in the Disclosure Package and the Final Prospectus; provided that the letter delivered on the Closing Date shall use a “cut-off date” not earlier than three business days prior to the date of such letter.

(g) Subsequent to the Execution Time or, if earlier, the dates as of which information is given in the Registration Statement (exclusive of any amendment thereof) and the Final Prospectus (exclusive of any amendment or supplement thereto), there shall not have been (i) any material change or decrease specified in the letter or letters referred to in paragraph (f) of this Section 6 or (ii) any change, or any development involving a prospective change, in or affecting the condition (financial or otherwise), earnings, business, properties or results of operations of the Partnership and its subsidiaries taken as a whole, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto) the effect of which, in any case referred to in clause (i) or (ii) above, is, in the sole judgment of the Representatives, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement (exclusive of any amendment thereof), the Disclosure Package and the Final Prospectus (exclusive of any amendment or supplement thereto).

(h) Subsequent to the Execution Time, there shall not have been any decrease in the rating of any of the Partnership’s debt securities by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 3(a)(62) under 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) Prior to the Closing Date, the Partnership shall have furnished to the Representatives such further information, certificates and documents as the Representatives may reasonably request.

If any of the conditions specified in this Section 6 shall not have been fulfilled when and as provided in this Agreement, or if any of the opinions and certificates mentioned above or elsewhere in this Agreement shall not be reasonably satisfactory in form and substance to the Representatives and counsel for the Underwriters, this Agreement and all obligations of the Underwriters hereunder may be canceled at, or at any time prior to, the Closing Date by the Representatives. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing.

7. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 6 hereof is not satisfied, because of any termination pursuant to clause (i) of Section 10 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 Underwriters, the Partnership will reimburse the Underwriters severally through the Representatives on demand for all reasonable 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 each Underwriter, the directors, officers, employees, affiliates (within the meaning of Rule 405 of the Securities Act who has participated in the distribution of securities as underwriters) and agents of each Underwriter and each person who controls any 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, each electronic road show used in connection with the offering of the Securities or the information contained in the final term sheet required to be prepared and filed pursuant to Section 5(b) hereto, 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 in order 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 any Underwriter through the Representatives specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Partnership may otherwise have.

(b) Each Underwriter severally and not jointly agrees to indemnify and hold harmless the Partnership, each of the General Partner’s directors, officers and employees, 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 each Underwriter, but only with reference to written information relating to such Underwriter furnished to the Partnership by or on behalf of such Underwriter through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which any 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”, (ii) the list of Underwriters and their respective participation in the sale of the Securities, (iii) the sentences related to concessions and reallowances, (iv) the paragraph related to stabilization, syndicate covering transactions and penalty bids and (v) the sentence related to market-making activities in any Preliminary Prospectus and the Final Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters 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 reasonably 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 reasonably 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. In no event shall such indemnifying party be liable for the fees and expenses of more than one counsel, in addition to one local counsel in each applicable jurisdiction, for all such indemnified parties in connection with any one action or separate but similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances. 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 each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include an admission of fault 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, the Partnership and the Underwriters severally 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 one or more of the Underwriters 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 Underwriters on the other from the offering of the Securities. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership and the Underwriters severally 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 Underwriters 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 Underwriters 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 Underwriters 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 Underwriters 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), in no event shall any Underwriter be required to contribute any amount in excess of the amount by which the total underwriting discounts and commissions received by such Underwriter with respect to the offering of the Securities exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the 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 an Underwriter within the meaning of either the Act or the Exchange Act and each director, officer, employee, affiliate and agent of an Underwriter shall have the same rights to contribution as such Underwriter, and each person who controls the Partnership within the meaning of either the Act or the Exchange Act, each officer of the General Partner who shall have signed the Registration Statement and each director of the General Partner 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. Default by an Underwriter. If any one or more Underwriters shall fail to purchase and pay for any of the Securities agreed to be purchased by such Underwriter or Underwriters hereunder and such failure to purchase shall constitute a default in the performance of its or their obligations under this Agreement, the remaining Underwriters shall be obligated

severally to take up and pay for (in the respective proportions which the principal amount of Securities set forth opposite their names in Schedule II hereto bears to the aggregate principal amount of Securities set forth opposite the names of all the remaining Underwriters) the Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase; provided, however, that in the event that the aggregate principal amount of Securities which the defaulting Underwriter or Underwriters agreed but failed to purchase shall exceed 10% of the aggregate principal amount of Securities set forth in Schedule II hereto, the remaining Underwriters shall have the right to purchase all, but shall not be under any obligation to purchase any, of the Securities, and if such nondefaulting Underwriters do not purchase all the Securities, this Agreement will terminate without liability to any nondefaulting Underwriter or the Partnership. In the event of a default by any Underwriter as set forth in this Section 9, the Closing Date shall be postponed for such period, not exceeding five Business Days, as the Representatives shall determine in order that the required changes in the Registration Statement and the Final Prospectus or in any other documents or arrangements may be effected. Nothing contained in this Agreement shall relieve any defaulting Underwriter of its liability, if any, to the Partnership and any nondefaulting Underwriter for damages occasioned by its default hereunder.

10. Termination. This Agreement shall be subject to termination in the absolute discretion of the Representatives, 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 common units shall have been suspended by the Commission or the New York Stock Exchange or trading in securities generally on the New York Stock Exchange 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, (iii) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services or (iv) 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 on financial markets is such as to make it, in the sole judgment of the Representatives, 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).

11. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership or the officers of the General Partner and of the Underwriters 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 any Underwriter or the Partnership or any of the officers, directors, employees, affiliates, 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.

14. 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 Underwriters and any affiliate through which it may be acting, on the other, (b) the Underwriters are acting as principal and not as an agent or fiduciary of the Partnership and (c) the Partnership’s engagement of the Underwriters 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 any of the Underwriters has advised or is currently advising the Partnership on related or other matters). The Partnership agrees that it will not claim that the Underwriters have 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.

(i) Each of the Enable Entities, other than Enable Energy Resources, LLC, Enable Gas Gathering, LLC, Enable Gathering & Processing, LLC and Enable Products, LLC (individually, a “Covered Enable Entity”), is validly existing as a limited partnership, limited liability company or corporation, as the case may be, and is in good standing under the laws of the State of Delaware or, in the case of Waskom Midstream, LLC, the State of Texas.

(ii) Each Covered Enable Entity is duly qualified to do business as a foreign corporation, limited liability company or limited partnership, as the case may be, in, and is in good standing under the laws of each jurisdiction so identified on Schedule V to this Agreement.

(iii) Each Covered Enable Entity has all requisite limited partnership, limited liability company or corporate power, as applicable, to own, lease and operate its respective properties and conduct its business, in each case in all material respects, as described in the Disclosure Package and the Final Prospectus.

The General Partner has the limited liability company power and authority necessary to act as the general partner of the Partnership.

(iv) The General Partner is the sole general partner of the Partnership and owns a noneconomic general partner interest in the Partnership; the General Partner Interest has been duly authorized and validly issued in accordance with the Partnership Agreement. The General Partner Interest is owned free and clear of any Liens (1) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as debtor is on file in the office of the Delaware Secretary of State or (2) otherwise known to us, without independent investigation, other than (A) restrictions on transferability contained in the Partnership Agreement, (B) Liens created by or arising under the Delaware LP Act, and (C) Liens described in the Disclosure Package or Final Prospectus.

(v) The General Partner owns all of the Incentive Distribution Rights; the Incentive Distribution Rights, and the limited partner interests represented thereby, have been duly authorized and validly issued in accordance with the Partnership Agreement and are fully paid (to the extent required under the Partnership Agreement); and the Incentive Distribution Rights are owned free and clear of any Liens (1) in respect of which a financing statement under the Uniform Commercial Code of the State of Delaware naming the General Partner as debtor is on file in the office of the Delaware Secretary of State or (2) otherwise known to us, without independent investigation, other than (A) restrictions on transferability contained in the Partnership Agreement, (B) Liens created by or arising under the Delaware LP Act, and (C) Liens described in the Disclosure Package or Final Prospectus.

(vi) The Underwriting Agreement has been duly authorized, executed and delivered by the Partnership.

(vii) The Indenture has been duly qualified under the Trust Indenture Act, and each of the Base Indenture and the Supplemental Indenture has been duly authorized, executed and delivered by the Partnership.

(viii) The Securities have been duly authorized, executed and delivered by the Partnership.

(ix) The Indenture constitutes a valid and binding agreement of the Partnership, enforceable against the Partnership in accordance with its terms, except as enforceability thereof may be limited (i) by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally, an implied covenant of good faith and fair dealing (ii) by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) public policy considerations relating to rights to indemnification or contribution.

(x) The Securities, when authenticated, issued and delivered in the manner provided for in the Indenture and delivered against payment of the purchase price for the Securities as provided in this Agreement, will constitute the valid and binding obligations of the Partnership enforceable against the Partnership in accordance with their terms, except as enforceability thereof may be limited by (i) bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws relating to or affecting creditors’ rights generally, an implied covenant of good faith and fair dealing, (ii) by general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and (iii) public policy considerations relating to rights to indemnification or contribution.

(xi) The offering, issuance or sale of the Securities as contemplated by this Agreement does not give rise under the formation, governing or other organizational documents of the Partnership or any material agreement or other instrument filed as an exhibit to the Partnership’s Annual Report on Form 10-K for the year ended December 31, 2017 or any Quarterly Report on Form 10-Q or Current Report on Form 8-K filed subsequent to the Partnership’s most recently completed fiscal year (collectively, the “Material Agreements”) to any rights for or relating to the registration of any securities of the Partnership, other than those that have been waived.

(xii) The Registration Statement automatically became effective under the Act on May 7, 2018. To our knowledge, based solely upon our review of the stop orders contained on the SEC’s website located at http://www.sec.gov/litigation/stoporders.shtml on the Closing Date, no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or threatened by the SEC. The filings of the Preliminary Prospectus and the Final Prospectus pursuant to Rule 424 under the Act were made in the manner and within the time period required by such Rule.

(xiii) The offering, issuance and sale of the Securities by the Partnership to be sold by it pursuant to the Underwriting Agreement, the execution, delivery and performance of the Underwriting Agreement by the Partnership, the execution and delivery of the Supplemental Indenture and the performance of the Indenture by the Partnership, and the consummation by the Partnership of the transactions contemplated thereby do not and will not (A) conflict with or

result in a breach or violation of any of the terms or provisions of, or constitute a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets of the Covered Enable Entities pursuant to any Material Agreement, (B) result in any violation of the provisions of any formation, governing or other organizational documents of any of the Covered Enable Entities, as applicable, or (C) result in the violation of the Delaware LP Act, the Delaware LLC Act, the laws of the State of Texas, the laws of the State of New York or federal law (provided that we express no opinion with respect to compliance with any federal or state securities or antifraud law) or any judgment, order, rule or regulation of any court or arbitrator or governmental or regulatory authority known to us, except, in the case of clauses (A) and (C) above, for any such conflict, breach or violation that would not, individually or in the aggregate, have a Material Adverse Effect or a material adverse effect on the ability of any of the Enable Entities to consummate the transactions contemplated by the Underwriting Agreement and the Indenture.

(xiv) No permit, consent, approval, authorization, order, registration, filing or qualification (“Consent”) under the Delaware LP Act, the Delaware LLC Act, the laws of the State of Texas, the laws of the State of New York or federal law is required in connection with the offering, issuance or sale of the Securities by the Partnership, or the execution, delivery and performance of the Underwriting Agreement and the Indenture by the Partnership, other than (a) such Consents required under state securities or “Blue Sky” laws, (b) such Consents that have been obtained or made, (c) qualification of the Indenture under the Trust Indenture Act and (d) filings with the Commission required in the performance by the Partnership of its obligations under Section 5 of the Underwriting Agreement.

(xv) The description of the Securities and the Indenture included in the Disclosure Package and the Final Prospectus under the captions “Description of the Notes” and “Description of the Senior Debt Securities” are accurate in all material respects.

(xvi) The Partnership is not and, after giving effect to the offering and sale of the Securities and the application of the proceeds thereof as described under “Use of Proceeds” in the Disclosure Package and the Final Prospectus, will not be an “investment company” as defined in the Investment Company Act of 1940, as amended.

(xvii) The statements set forth in the Disclosure Package and the Final Prospectus under the caption “Certain U.S. Federal Income Tax Consequences,” insofar as they purport to constitute a summary of United States federal income tax law and regulations or legal conclusions with respect thereto, accurately summarize the matters described therein in all material respects, subject to the assumptions and qualifications set forth therein.

In addition, such counsel shall state that they have participated in conferences with officers and other representatives of the Enable Entities, the independent registered public accountants of the Partnership, the Representatives and counsel for the Underwriters, at which the contents of the Registration Statement, the Disclosure Package and the Final Prospectus and related matters were discussed, and although such counsel has not independently verified, is not passing upon, and is not assuming any responsibility for the accuracy, completeness or fairness of the statements contained in, the Registration Statement, the Disclosure Package and the Final Prospectus (except to the extent specified in paragraphs (xv) and (xvii) of the foregoing opinion), based on the foregoing, no facts have come to such counsel’s attention that lead such counsel to believe that:

(A) each of the Registration Statement, as of the date of the Underwriting Agreement, and the Final Prospectus, as of the date of the Final Prospectus, did not appear on its face to be appropriately responsive in all material respects with the requirements of the Securities Act and the rules and regulations thereunder, except that such counsel need not express any view as to the antifraud provisions of the U.S. federal securities laws and the rules and regulations promulgated under such provisions,

(B) the Registration Statement, as of the latest Effective Date, contained an untrue statement of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading,

(C) the Disclosure Package, as of the Applicable Time, included an untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or

(D) the Final Prospectus, as of its date or as of the Closing Date, included or includes an untrue statement of a material fact or omitted or omits to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

it being understood that such counsel expresses no statement or belief with respect to (i) the financial statements and related schedules, including the notes thereto and independent registered public accountants’ reports thereon, included or incorporated by reference in the Registration Statement, the Disclosure Package or the Final Prospectus, (ii) any other financial or accounting information included or incorporated by reference in or omitted from the Registration Statement, the Disclosure Package or the Final Prospectus and (iii) representations and warranties and other statements of fact included in the exhibits to the Registration Statement, any documents incorporated by reference or the Trustee’s Statement of Eligibility on Form T-1.

In rendering such opinion, such counsel may (A) rely in respect of matters of fact, to the extent such counsel deems appropriate, upon representations of the Partnership set forth in this Agreement and upon certificates of officers and employees of the Enable Entities and upon information obtained from public officials, (B) assume that all documents submitted to them as originals are authentic, that all copies submitted to them conform to the originals thereof, and that the signatures on all documents examined by them are genuine, (C) state that their opinion is limited to the Delaware LP Act, the Delaware LLC Act, the laws of the State of Texas, the laws of the State of New York or federal law, (D) with respect to the opinions expressed in paragraph (ii) above as to the due qualification or registration as a foreign corporation, limited partnership or limited liability company, as the case may be, of each of the Covered Enable Entities, state that such opinions are based upon certificates or other statements of foreign qualification or registration provided by the Secretary of State of the states listed on Schedule B hereto (each of which shall be dated as of a recent date and shall be provided to the Underwriters or their counsel), and (E) state that they express no opinion with respect to (i) any permits to own or operate any real property or (ii) foreign, state or local taxes or tax statutes to which any of the limited partners of the Partnership or any of the members of the General Partner may be subject.
