(e)                                   During the period beginning from the date hereof and continuing to and including the date 180 days after the date of the Prospectus, not to (i) offer, sell, contract to sell, pledge, grant any option to purchase, make any short sale or otherwise transfer or dispose of, directly or indirectly, or file with the Commission a registration statement under the Securities Act relating to, any securities of the Partnership that are substantially similar to the Units, including but not limited to any options or warrants to purchase Common Units or any securities that are convertible into or exchangeable for, or that represent the right to receive, Common Units or any such substantially similar securities, or publicly disclose the intention to make any offer, sale, pledge, disposition or filing or (ii) enter into any swap or other agreement that transfers, in whole or in part, any of the economic consequences of ownership of the Common Units or any such other securities, whether any such transaction described in clause (i) or (ii) above is to be settled by delivery of Common Units or such other securities, in cash or otherwise, without the prior written consent of the Representatives on behalf of the Underwriters;

The restrictions contained in the preceding paragraph shall not apply to the issuance by the Partnership of (i) Common Units pursuant to (A) this Agreement, (B) employee benefit plans, qualified option plans or other employee compensation plans existing on the date hereof, including, without limitation, under the Partnership’s Long-Term Incentive Plan, (C) Section 5.10 of the Partnership Agreement in connection with the conversion of the Partnership’s Class B Preferred Units (as defined in the Partnership Agreement) in accordance with the terms thereof, (D) that certain Amended and Restated Shared Services Agreement, dated as of March 6, 2015, between the Partnership and Holdings, (E) a private placement exempt from registration under the Securities Act to Sanchez Energy as disclosed in the Partnership’s Current Report on Form 8-K, filed November 16, 2016 and (ii) PIK Units (as defined in the Partnership Agreement) pursuant to Section 5.10 of the Partnership Agreement.

(a)                                  The Partnership represents and agrees that, without the prior consent of the Representatives, it has not made and will not make any offer relating to the Units that would constitute a “free writing prospectus” as defined in Rule 405 under the Securities Act; each Underwriter represents and agrees that, without the prior written consent of the Partnership and the Representatives, it has not made and will not make any offer relating to the Units that would constitute a free writing prospectus; any such free writing prospectus the use of which has been consented to by the Partnership and the Representatives is listed on Schedule II(a)  hereto;

(b)                                  The Partnership has complied and will comply with the requirements of Rule 433 under the Securities Act applicable to any Issuer Free Writing Prospectus, including timely filing with the Commission or retention where required and legending; and

(c)                                   The Partnership agrees that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Pricing Disclosure Package or the Prospectus or would include an 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 then prevailing, not misleading, the Partnership will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Partnership by an Underwriter through the Representatives expressly for use therein.

7.                                 The Partnership covenants and agrees with the several Underwriters that the Partnership will pay or cause to be paid the following: (i) the fees, disbursements and expenses of the Partnership’s counsel and accountants in connection with the registration of the Units under the Securities Act and all other expenses in connection with the preparation, printing, reproduction and filing of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus and the Prospectus and amendments and supplements thereto and the mailing and delivering of copies thereof to the Underwriters and dealers; (ii) the cost of printing or producing any Agreement among Underwriters, this Agreement, any Blue Sky Memorandum, closing documents (including any compilations thereof) and any other documents in connection with the offering, purchase, sale and delivery of the Units; (iii) all expenses in connection with the qualification of the Units for offering and sale under state securities laws as provided in Section 5(b)  hereof, including the fees and disbursements of counsel for the Underwriters in connection with such qualification and in connection with the Blue Sky survey(s); (iv) any filing fees incident to, and the fees and disbursements of counsel for the Underwriters in connection with, any required reviews by FINRA of the terms of the sale of the Units; (v) the cost of preparing certificates for the Units; (vi) the cost and charges of any transfer agent or registrar or dividend disbursing agent; (vii) all fees and expenses in connection with listing the Units on the Exchange; (viii) all expenses incident to the “road show” for the offering of the Units, including the cost of any chartered airplane or other transportation in connection therewith; and (ix) all other costs and expenses incident to the performance of its obligations hereunder which are not otherwise specifically provided for in this Section. It is understood, however, that, except as provided in this Section, and Sections 9 and 12 hereof, the Underwriters will pay all of their own costs and expenses, including the fees of their counsel, transfer taxes on resale of any of the Units by them, and any advertising expenses connected with any offers they may make.

22

8.                                 The obligations of the Underwriters hereunder, as to the Units to be delivered at each Time of Delivery, shall be subject, in their discretion, to the condition that all representations and warranties and other statements of the Partnership herein are, at and as of such Time of Delivery, true and correct, the condition that the Partnership shall have performed all of their obligations hereunder theretofore to be performed by it, and the following additional conditions:

(b)                                  Baker Botts L.L.P., counsel for the Underwriters, shall have furnished to the Representatives such written opinion or opinions, dated such Time of Delivery, in form and substance satisfactory to the Representatives, with respect to such matters the Representatives may reasonably request, and such counsel shall have received such papers and information as they may reasonably request to enable them to pass upon such matters;

(iii)                                a statement that they have examined the Registration Statement, the Prospectus and the Pricing Disclosure Package, and, in their opinion, (A)(1) the Registration Statement, as of the applicable effective date as to each part of the Registration Statement and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, (2) the Prospectus, as of its date and on the applicable Time of Delivery, and (3) the Pricing Disclosure Package, as of the Applicable Time, did not and do not contain any untrue statement of a material fact and did not and do not omit to state a material fact required to be stated therein or necessary to make the statements therein (except in the case of the Registration Statement, in the light of the circumstances under which they were made) not misleading, and (B) since the applicable effective date as to each part of the Registration Statement and as of the applicable filing date as to the Prospectus and any amendment or supplement thereto, no event has occurred that should have been set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth; and

(iv)                               the matters set forth in subsections (a) and (f) of this Section.

9.                                 (a)  The Partnership agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees, affiliates and agents of each Underwriter and each person who controls any Underwriter within the meaning of either the Securities 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 Securities 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 Units as originally filed or in any amendment thereof, or in any Preliminary Prospectus, the Prospectus, or 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 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 its directors, each of its officers who signs the Registration Statement, and each person who controls the Partnership within the meaning of either the Securities 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.

25

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 Units and, under the heading “Underwriting”, (ii) the list of Underwriters and their respective participation in the sale of the Units, (iii) the sentences related to concessions and reallowances and (iv) the paragraph related to stabilization, syndicate covering transactions and penalty bids in the Preliminary Prospectus and the Prospectus constitute the only information furnished in writing by or on behalf of the several Underwriters for inclusion in the Preliminary Prospectus, the Prospectus or any Issuer Free Writing Prospectus.

(c)                                   Promptly after receipt by an indemnified party under this Section 9 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 9 , 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 each indemnified party from all liability arising out of such claim, action, suit or proceeding and (ii) does not include 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 9 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 Units. If the allocation provided by the immediately

26

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 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 Units 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 Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  For purposes of this Section 9 , each person who controls an Underwriter within the meaning of either the Securities 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 Securities 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).

10.                          (a)  If any Underwriter shall default in its obligation to purchase the Units which it has agreed to purchase hereunder, the Representatives may in the Representatives’ discretion arrange for the Representatives or another party or other parties to purchase such Units on the terms contained herein.  If within thirty-six hours after such default by any Underwriter the Representatives do not arrange for the purchase of such Units, then the Partnership shall be entitled to a further period of thirty-six hours within which to procure another party or other parties satisfactory to the Representatives to purchase such Units on such terms.  In the event that, within the respective prescribed periods, the Representatives notify the Partnership that the Representatives have so arranged for the purchase of such Units, or the Partnership notifies the Representatives that it has so arranged for the purchase of such Units, the Representatives or the Partnership shall have the right to postpone Time of Delivery for a period of not more than seven days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus, or in any other documents or arrangements, and the Partnership agrees to file promptly any amendments or supplements to the Registration Statement or the Prospectus which in the Representatives’ opinion may thereby be made necessary. The term “Underwriter” as used in this Agreement shall include any person substituted under this Section with like effect as if such person had originally been a party to this Agreement with respect to such Units.

(b)                                  If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the Representatives and the Partnership as provided in subsection (a) above, the aggregate number of such Units which remains unpurchased does not exceed one-eleventh of the aggregate

27

number of all the Units to be purchased at such Time of Delivery, then the Partnership shall have the right to require each non-defaulting Underwriter to purchase the number of Common Units which such Underwriter agreed to purchase hereunder at such Time of Delivery and, in addition, to require each non-defaulting Underwriter to purchase its pro rata share (based on the number of Units which such Underwriter agreed to purchase hereunder) of the Units of such defaulting Underwriter or Underwriters for which such arrangements have not been made; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

(c)                                   If, after giving effect to any arrangements for the purchase of the Units of a defaulting Underwriter or Underwriters by the Representatives and the Partnership as provided in subsection (a) above, the aggregate number of such Units which remains unpurchased exceeds one-eleventh of the aggregate number of all the Units to be purchased at such Time of Delivery, or if the Partnership shall not exercise the right described in subsection (b)  above to require non-defaulting Underwriters to purchase Units of a defaulting Underwriter or Underwriters, then this Agreement (or, with respect to the Second Time of Delivery, the obligations of the Underwriters to purchase and of the Partnership to sell the Optional Units) shall thereupon terminate, without liability on the part of any non-defaulting Underwriter or the Partnership, except for the expenses to be borne by the Partnership and the Underwriters as provided in Section 7 hereof and the indemnity and contribution agreements in Section 9 hereof; but nothing herein shall relieve a defaulting Underwriter from liability for its default.

11.                          The respective indemnities, agreements, representations, warranties and other statements of the Partnership and the several Underwriters, as set forth in this Agreement or made by or on behalf of them, respectively, pursuant to this Agreement, shall remain in full force and effect, regardless of any investigation (or any statement as to the results thereof) made by or on behalf of any Underwriter or any controlling person of any Underwriter, or the Partnership, or any officer or director of the General Partner or controlling person of the Partnership, and shall survive delivery of and payment for the Units.

12.                          If this Agreement shall be terminated pursuant to Section 10 hereof, the Partnership shall not then be under any liability to any Underwriter except as provided in Sections 7 and 9 hereof; but, if for any other reason, any Units are not delivered by or on behalf of the Partnership as provided herein, the Partnership will reimburse the Underwriters through the Representatives for all out-of-pocket expenses approved in writing by the Representatives, including fees and disbursements of counsel, reasonably incurred by the Underwriters in making preparations for the purchase, sale and delivery of the Units not so delivered, but the Partnership shall then be under no further liability to any Underwriter except as provided in Sections 7 and 9 hereof.

13.                          In all dealings hereunder, the Representatives shall act on behalf of each of the Underwriters, and the parties hereto shall be entitled to act and rely upon any statement, request, notice or agreement on behalf of any Underwriter made or given by the Representatives.

All statements, requests, notices and agreements hereunder shall be in writing, and if to the Underwriters shall be delivered or sent by mail, telex or facsimile transmission to Citigroup Global Markets Inc. at 388 Greenwich Street, New York, New York 10013 Attention: General Counsel, facsimile number 1-646-291-1469; and RBC Capital Markets, LLC at 200 Vesey Street New York, New York 10281 Attention: Equity Syndicate, facsimile number 1-(212) 428-6260; and if to the Partnership shall be delivered or sent by mail, telex or facsimile transmission to the address of the Partnership set forth in the Registration Statement, Attention: Secretary; provided, however, that any notice to an Underwriter pursuant to Section 9(c)  hereof shall be delivered or sent by mail, telex or facsimile transmission to such Underwriter at its address set forth in its

28

Underwriters’ Questionnaire, or telex constituting such Questionnaire, which address will be supplied to the Partnership by the Representatives upon request.  Any such statements, requests, notices or agreements shall take effect upon receipt thereof.

In accordance with the requirements of the USA Patriot Act (Title III of Pub.
