Ladies and Gentlemen:

Access Midstream Partners, L.P., a Delaware limited partnership (the “Partnership”), confirms its agreement (this “Agreement”) with Citigroup Global Markets Inc., Goldman, Sachs & Co. and Wells Fargo Securities, LLC (the “Managers”) as follows:

1. Description of Units. The Partnership proposes to issue and sell through or to the Managers, as sales agents and/or principals, common units representing limited partner interests in the Partnership (the “Common Units”), having an aggregate gross sales price of up to $300,000,000 (the “Offered Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. For purposes of selling the Offered Units through the Managers, the Partnership hereby appoints the Managers as exclusive agents of the Partnership for the purpose of selling the Offered Units pursuant to this Agreement and each Manager agrees to use its commercially reasonable efforts to sell the Offered Units on the terms and subject to the conditions stated herein. The Partnership agrees that whenever it determines to sell the Offered Units directly to any Manager as principal, it will enter into a separate agreement (each, a “Terms Agreement”) in substantially the form of Annex I hereto, relating to such sale in accordance with Section 3 of this Agreement. Certain terms used herein are defined in Section 21 hereof. Access Midstream Partners GP, L.L.C., a Delaware limited liability company (the “General Partner”) and a wholly owned subsidiary of Access Midstream Ventures, L.L.C., a Delaware limited liability company (“Midstream Ventures”), is the general partner of the Partnership and owns a 2% general partner interest in the Partnership. All of the Partnership’s activities are conducted through Access MLP Operating, L.L.C., a Delaware limited liability company wholly owned by the Partnership (“OLLC”). The Partnership, the General Partner and OLLC are sometimes referred to herein collectively as the “Partnership Parties” and each a “Partnership Party,” and the Partnership Parties, together with the Partnership’s subsidiaries, sometimes referred to herein collectively as the “Operating Subsidiaries,” are sometimes referred to as the “Partnership Entities” and each a “Partnership Entity.”

2. Representations and Warranties. The Partnership Parties, jointly and severally, represent and warrant to, and agree with, each of the Managers at the Execution Time and on each such time that the following representations and warranties are repeated or deemed to be made pursuant to this Agreement, as set forth below.

(a) Registration and No Stop Order. The Partnership meets the requirements for use of Form S-3 under the Securities Act and has prepared and filed with the Commission a registration statement (File No. 333-189963) on Form S-3, including a related Base Prospectus, for registration under the Securities Act of the offering and sale of the Offered Units (the “Registration Statement”). Such Registration Statement, including any amendments thereto filed prior to the Execution Time or prior to any such time this representation is repeated or deemed to be made with respect to the Offered Units has (i) been prepared by the Partnership in conformity with the requirements of the Securities Act and the rules and regulations (the “Rules and Regulations”) of the Commission thereunder, (ii) been filed with the Commission under the Securities Act and (iii) become effective under the Securities Act. Copies of such Registration Statement have been delivered by the Partnership to the Managers. The Commission has not issued any order preventing or suspending the use of the Base Prospectus, the Prospectus Supplement or any Issuer Free Writing Prospectus or suspending the effectiveness of the Registration Statement, and no proceeding or examination for such purpose has been instituted or threatened by the Commission. The Commission has not notified the Partnership of any objection to the use of the form of Registration Statement. The Registration Statement, at the Execution Time, each such time this representation is repeated or deemed to be made, and at all times during which a prospectus is required by the Securities Act to be delivered (whether physically or through compliance with Rule 172 or any similar rule) in connection with any offer or sale of Common Units, 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. Any reference herein to the Registration Statement, the Base Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, the Prospectus Supplement or the 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, the Prospectus Supplement or the Prospectus, as the case may be, deemed to be incorporated therein by reference.

(b) Registration Statement Not Subject of Pending Proceeding. The Registration Statement is not the subject of a pending proceeding or examination under Section 8(d) or 8(e) of the Securities Act, and the Partnership is not the subject of a pending proceeding under Section 8A of the Securities Act in connection with the offering of the Offered Units.

(c) Obligation to File New Registration Statement. To the extent that the Registration Statement is not available for the sales of the Offered Units as contemplated by this Agreement, the Partnership shall file a new registration statement with respect to any additional Common Units necessary to complete such sales of the Offered Units and shall cause such registration statement to become effective as promptly as practicable. After the effectiveness of any such registration statement, all references to “Registration Statement” included in this Agreement shall be deemed to include such new registration statement, including all documents

incorporated by reference therein pursuant to Item 12 of Form S-3, and all references to “Base Prospectus” included in this Agreement shall be deemed to include the final form of prospectus, including all documents incorporated therein by reference, included in any such registration statement at the time such registration statement became effective.

(e) No Material Misstatements or Omissions in Disclosure Package. At the Execution Time, at each Applicable Time, at each Settlement Date and Time of Delivery, the Disclosure Package did not and 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 Parties make no representations or warranties as to the information contained in or omitted from the Disclosure Package in reliance upon and in conformity with information furnished in writing to the Partnership by any Manager specifically for inclusion in the Disclosure Package.

(f) No Material Misstatements or Omissions in Issuer Free Writing Prospectus.

The summary historical and pro forma financial information incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus is fairly presented in all material respects and prepared on a basis consistent with the audited and unaudited historical financial statements from which it has been derived. The pro forma financial statements incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus have been prepared in all material respects in accordance with the applicable accounting requirements of Article 11 of Regulation S-X of the Commission, except to the extent disclosed therein; the assumptions used in the preparation of such pro forma financial statements are, in the opinion of the management of the Partnership, reasonable; and the pro forma adjustments reflected in such pro forma financial statements have been properly applied to the historical amounts in compilation of such pro forma financial statements. There are no financial statements (historical or pro forma) that are required to be included or incorporated by reference in the Disclosure Package or the Prospectus that are not so included or incorporated by reference.

3. Sale and Delivery of Offered Units.

(a) Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to issue and sell Offered Units from time to time through the Managers, acting as sales agents, and each Manager agrees to use its commercially reasonable efforts to sell, as sales agents for the Partnership, the Offered Units on the following terms.

(i) The Offered Units are to be sold on a daily basis or otherwise as shall be agreed to by the Partnership and any Manager on any day that (A) is a trading day for the NYSE, (B) the Partnership, through any of the individuals listed as Authorized Representatives on Schedule II hereto, has instructed such Manager by telephone (confirmed promptly by electronic mail) to make such sales and (C) the Partnership has satisfied its obligations under Section 6 of this Agreement. The Partnership will designate the maximum amount of the Offered Units to be sold by such Manager daily as agreed to by such Manager (in any event not in excess of the amount available for issuance under the Prospectus and the currently effective Registration Statement) and the minimum price per Offered Unit at which such Offered Units may be sold. Subject to the terms and conditions hereof, such Manager shall use its commercially reasonable efforts to sell on a particular day all of the Offered Units designated for sale by the Partnership on such day. The gross sales price of the Offered Units sold under this Section 3(a) shall be the market price for the Common Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Offered Units. For the avoidance of doubt, the Partnership shall submit instructions to sell Offered Units to only one Manager, if any, on any single trading day.

(ii) The Partnership acknowledges and agrees that (A) there can be no assurance that any Manager will be successful in selling the Offered Units, (B) no Manager will incur any liability or obligation to the Partnership or any other person or entity if such Manager does not sell Offered Units for any reason other than a failure by such Manager to use its commercially reasonable efforts consistent with its normal trading and sales practices and applicable law and regulations to sell such Offered Units as required under this Agreement, and (C) no Manager shall be under any obligation to purchase Offered Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Partnership in writing pursuant to a Terms Agreement.

(iii) The Partnership shall not authorize the issuance and sale of, and no Manager shall be obligated to use its commercially reasonable efforts to sell, any Offered Units at a price lower than the minimum price therefor designated from time to time by the Partnership’s Board of Directors (the “Board”), or a pricing committee duly authorized thereby, and notified to such Manager in writing. The Partnership or any Manager may, upon notice to the other party hereto by telephone (confirmed promptly by electronic mail), suspend the offering of the Offered Units with respect to which such Manager is acting as sales agent for any reason and at any time; provided, however, that such suspension or termination shall not affect or impair the parties’ respective obligations with respect to the Offered Units sold hereunder prior to the giving of such notice.

(iv) Each Manager hereby covenants and agrees not to make any sales of the Offered Units on behalf of the Partnership, pursuant to this Section 3(a), other than (A) directly on or through a national securities exchange or facility thereof, a trading facility of a national securities association, an alternative trading system, an electronic communication network, a “dark pool” or any similar market venue and (B) such other sales of the Offered Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be agreed by the Partnership and such Manager pursuant to a Terms Agreement.

(v) The compensation to each Manager for sales of the Offered Units with respect to which such Manager acts as sales agent under this Agreement shall be up to 2.0% of the gross sales price of the Offered Units sold pursuant to this Section 3(a) and payable as described in the succeeding subsection (vi) below. The foregoing rate of compensation shall not apply when such Manager acts as principal, in which case the Partnership may sell Offered Units to such Manager as principal at a price agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The remaining proceeds after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”) shall constitute the net proceeds to the Partnership for such Offered Units (the “Net Proceeds”).

(vi) Each Manager shall provide written confirmation (which may be by facsimile or electronic mail) to the Partnership following the close of trading on the NYSE each day in which the Offered Units are sold under this Section 3(a) setting forth the number of the Offered Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Partnership, any Transaction Fees deducted pursuant to Section 3(a)(v) and the compensation payable by the Partnership to such Manager with respect to such sales. Such compensation shall be set forth and invoiced in periodic statements from such Manager to the Partnership, with payment to be made by the Partnership promptly after its receipt thereof.

(vii) Settlement for sales of the Offered Units pursuant to this Section 3(a) will occur on the third Business Day following the date on which such sales are made (each such day, a “Settlement Date”). On each Settlement Date, the Offered Units sold through any Manager for settlement on such date shall be issued and delivered by the Partnership to such Manager against payment of the aggregate gross sales proceeds less any Transaction Fees for the sale of such Offered Units. Settlement for all such Offered Units shall be effected by free delivery of the Offered Units to such Manager’s account at The Depository Trust Company (“DTC”) in return for payments in same day funds delivered to the account designated by the Partnership. If the Partnership or its transfer agent (if applicable) shall default on its obligation to deliver the Offered Units on any Settlement Date, the Partnership shall (A) indemnify and hold such Manager harmless against any loss, claim or damage arising from or as a result of such default by the Partnership and (B) pay such Manager any commission to which it would otherwise be entitled absent such default. If any Manager breaches this Agreement by failing to deliver the aggregate gross sales proceeds less any Transaction Fees to the Partnership on any Settlement Date for the Offered Units delivered by the Partnership, such Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation to which such Manager is entitled.

(viii) At each Applicable Time, Settlement Date and Representation Date (as defined in Section 4(k)), the Partnership shall be deemed to have affirmed each representation and warranty contained in this Agreement as if such representation and warranty were made as of such date, modified as necessary to relate to the Disclosure Package and the Prospectus as amended as of such date and to reflect such necessary modifications as are not material and approved by the Managers in advance. Any obligation of any Manager to use its commercially reasonable efforts to sell the Offered Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein, to the performance by the Partnership of its obligations hereunder and to the continuing satisfaction of the additional conditions specified in Section 6 of this Agreement.

(b) If the Partnership wishes to issue and sell the Offered Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify the Managers of the proposed terms of such Placement. If any Manager, each acting as principal, wishes to accept such proposed terms (which it may decline to do for any reason in its sole discretion) or, following discussions with the Partnership wishes to accept amended terms, such Manager(s) and the Partnership will enter into a Terms Agreement setting forth the terms of such Placement. The terms set forth in a Terms Agreement will not be binding on the Partnership or such Manager(s) unless and until the Partnership and such Manager(s) have each executed such Terms Agreement accepting all of the terms of such Terms Agreement. In the event of a conflict between the terms of this Agreement and the terms of a Terms Agreement, the terms of such Terms Agreement will control.

(c) Each sale of the Offered Units to any Manager shall be made in accordance with the terms of this Agreement and, if applicable, a Terms Agreement, which will provide for the sale of such Offered Units to, and the purchase thereof by, such Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Offered Units by such Manager. The commitment of any Manager to purchase the Offered Units pursuant to any Terms Agreement shall be deemed to have been made on the basis of the representations and warranties of the Partnership herein contained and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Offered Units to be purchased by such Manager pursuant thereto, the price to be paid to the Partnership for such Offered Units, any provisions relating to rights of, and default by, underwriters acting together with such Manager in the reoffering of the Offered Units, and the time and date (each such time and date being referred to herein as a “Time of Delivery”) and place of delivery of and payment for such Offered Units. Such Terms Agreement shall also specify any requirements for opinions of counsel, accountants’ letters and officers’ certificates pursuant to Section 6 of this Agreement and any other information or documents required by such Manager.

(d) The Partnership will not request any sales hereunder that exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Offered Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Offered Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to the Managers in writing.

(e) If any party has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M are not satisfied with respect to the Offered Units, it shall promptly notify the other parties and sales of the Offered Units under this Agreement and any Terms Agreement shall be suspended until that or other exemptive provisions have been satisfied in the judgment of each party.

(f) Notwithstanding any other provision of this Agreement, the Partnership shall not request the sale of any Offered Units that would be sold, and the Managers shall not be obligated to sell, during any period in which the Partnership is in possession of material non-public information.

4. Agreements. Each of the Partnership Parties, jointly and severally, covenants and agrees with each Manager that:

(a) During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Securities Act, prior to filing any amendment of the Registration Statement or supplement (including the Prospectus) to the Base Prospectus or any Rule 462(b) Registration Statement, the Partnership will furnish to the Managers for review a copy of each such proposed amendment or supplement, and the Partnership shall not use any such proposed amendment or supplement to which any Manager reasonably objects. The Partnership has properly completed the Prospectus, in a form approved by the Managers, and filed such Prospectus, as amended at the Execution Time, with the Commission pursuant to the applicable paragraph of Rule 424(b) by the Execution Time and will cause any supplement to the Prospectus to be properly completed, in a form approved by the Managers, and will file such supplement with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed thereby and will provide evidence satisfactory to the Managers of such timely filing. The Partnership will promptly advise the Managers (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b) or when any Rule 462(b) Registration Statement shall have been filed with the Commission, (ii) when, during any period when the delivery of a prospectus (whether physically or through compliance with Rule 172 or any similar rule) is required under the Securities Act in connection with the offering or sale of the Offered Units, 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 any Rule 462(b) Registration Statement, or for any supplement to the 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 Offered Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its best efforts to prevent the issuance of any such stop order or the occurrence of any such suspension or objection to the use of the Registration Statement and, upon such issuance, occurrence or notice of objection, to obtain as soon as possible the withdrawal of such stop order or relief from such occurrence or objection, including, if necessary, by filing an amendment to the Registration Statement or a new registration statement and using its best efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) If, at any time on or after an Applicable Time but prior to the related Settlement Date or Time of Delivery, any event occurs as a result of which the Disclosure Package would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made or the circumstances then prevailing not misleading, the Partnership will (i) notify promptly the Managers so that any use of the Disclosure Package may cease until it is amended or supplemented; (ii) amend or supplement the Disclosure Package to correct such statement or omission; and (iii) supply any amendment or supplement to the Managers in such quantities as the Managers may reasonably request.

(c) During any period when the delivery of a prospectus relating to the Offered Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172) to be delivered under the Securities Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein in the light of the circumstances under which they were made at such time not misleading, or if it shall be necessary to amend the Registration Statement, file a new registration statement or supplement the Prospectus to comply with the Securities Act or the Exchange Act or the respective rules thereunder, including in connection with use or delivery of the Prospectus, the Partnership promptly will (i) notify the Managers of any such event, (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement or new registration statement which will correct such statement or omission or effect such compliance, (iii) use its best efforts to have any amendment to the Registration Statement or new registration statement declared effective as soon as practicable in order to avoid any disruption in use of the Prospectus and (iv) supply any supplemented Prospectus to the Managers in such quantities as the Managers may reasonably request.

(d) As soon as practicable after the Effective Date and in any event not later than 16 months after the date hereof, the Partnership will make generally available via the Commission’s Electronic Data Gathering, Analysis and Retrieval (EDGAR) System, to the Partnership’s security holders and to the Managers an earnings statement of the Partnership and its subsidiaries (which need not be audited) complying with Section 11(a) of the Securities Act and the Rules and Regulations (including, at the option of the Partnership, Rule 158).

(e) The Partnership will furnish to the Managers and counsel for the Managers, without charge, as many copies of the Registration Statement (including exhibits thereto), the Prospectus and each Issuer Free Writing Prospectus and any supplement thereto and any documents incorporated by reference therein as the Managers may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(f) The Partnership will promptly from time to time take such action as the Managers may reasonably request to qualify the Offered Units for offering and sale under the securities laws of such jurisdictions as the Managers may request and to comply with such laws so as to permit the continuance of sales and dealings therein in such jurisdictions for as long as may be necessary to complete the distribution of the Offered Units; provided that in connection therewith the Partnership shall not be required 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.

(g) The Partnership agrees that, unless it has or shall have obtained the prior written consent of the Managers, and the Managers agree 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 Offered Units that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Partnership with the Commission or retained by the Partnership under Rule 433; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule I hereto. Any such free writing prospectus consented to by the Managers or the Partnership is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership agrees that (i) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (ii) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

(h) At any time that sales of the Offered Units have been made but not settled or at any time the Partnership has outstanding with any Manager any instructions to sell Offered Units but such instructions have not been fulfilled or cancelled, the Partnership will not directly or indirectly, (1) offer to sell, sell, pledge or otherwise dispose of (or enter into any transaction or device that is designed to, or could be expected to, result in the disposition by any person at any time in the future of), any Common Units or securities convertible into or exchangeable for Common Units (other than the Offered Units and Common Units issued pursuant to employee benefit plans, qualified option plans or other employee compensation plans existing on the date hereof or pursuant to currently outstanding options, warrants or rights), or sell or grant options, rights or warrants with respect to any Common Units or securities convertible into or exchangeable for Common Units (other than the grant of options pursuant to option plans existing on the date hereof), (2) enter into any swap or other derivatives transaction agreement that transfers to another, in whole or in part, any of the economic benefits or risks of ownership of such Common Units, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Units or other securities, in cash or otherwise, (3) file or cause to be filed a registration statement, including any amendments, with respect to the registration of any Common Units or securities convertible, exercisable or exchangeable into Common Units or any other securities of the Partnership (other than any registration statement on Form S-8 or any registration statement filed in connection with an issuance made pursuant to clause (i) below), or (4) publicly disclose the intention to do any of the foregoing without, in each case, giving the Managers at least three Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction; provided, however, (A) that the Partnership may issue and sell Common Units pursuant to this Agreement or any Terms Agreement, (B) the Partnership may file a registration statement on Form S-8 or issue and sell Common Units or securities convertible into or exchangeable for Common Units pursuant to any long-term incentive plan, management incentive compensation plan, employee unit option plan, unit ownership plan or dividend reinvestment plan of the Partnership in effect at the Execution Time and (C) the Partnership may issue Common Units issuable upon the conversion, vesting or

exercise of securities (including long-term incentive plan awards, options and warrants) outstanding at the Execution Time. In the event that notice of a proposed sale or other action is provided by the Partnership pursuant to this Section 4(h), the Managers may (and shall if requested by the Partnership) suspend activity under this Agreement for such period of time as may be requested by the Partnership or as may be deemed appropriate by the Managers.

(i) The Partnership will not (i) 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 Common Units to facilitate the sale or resale of the Offered Units or (ii) sell, bid for, purchase or pay any person (other than as contemplated by this Agreement or any Terms Agreement) any compensation for soliciting purchases of the Offered Units.

(i) Since the respective dates as of which information is disclosed in the Registration Statement, the Disclosure Package and the Prospectus, except as otherwise stated therein, there shall not have been any change, or any development that would reasonably be expected to result in a prospective change, in the financial condition, earnings, business or operations of the Partnership Entities (taken as a whole) from that set forth or contemplated in the Prospectus, the effect of which is, in the judgment of the Managers, so material and adverse as to make it impracticable or inadvisable to proceed with the public offering or the delivery of the Offered Units on the terms and in the manner contemplated in the Prospectus.

(j) At any time that sales of the Offered Units have been made but not settled or at any time the Partnership has outstanding with any Manager any instructions to sell Offered Units but such instructions have not been fulfilled or cancelled no downgrading shall have occurred in the rating accorded the Partnership’s debt securities by any “nationally recognized statistical rating organization” (as that term is defined under Section 3(a)(62) of the Exchange Act).

7. Indemnification and Contribution.

(a) The Partnership Parties, jointly and severally, shall indemnify, defend and hold harmless each Manager, its partners, directors, officers, employees, agents, and members, any person who controls any Manager within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and any “affiliate” (within the meaning of Rule 405 under the Securities Act) of such Manager, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, any such Manager or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership) or arises out of or is based upon any omission or alleged omission to state a material fact required to be stated therein or necessary to make the statements therein not misleading, except

insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Registration Statement or arises out of or is based upon any omission or alleged omission to state a material fact in the Registration Statement in connection with such information, which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact included in any Prospectus (the term Prospectus for the purpose of this Section 7(a) being deemed to include the Disclosure Package, the Prospectus, any Issuer Free Writing Prospectus and any amendments or supplements to the foregoing) or in any “issuer information” (as defined in Rule 433 under the Securities Act) of the Partnership or arises out of or is based upon any omission or alleged omission 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, except, with respect to such Prospectus, insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact included in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, such Prospectus or arises out of or is based upon any omission or alleged omission to state a material fact in such Prospectus in connection with such information, which material fact was not included in such information and which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading. The Partnership Parties, jointly and severally, agree to reimburse such indemnified person for any legal or other expenses reasonably incurred by such indemnified person in connection with investigating, preparing or defending against any loss, claim, damage, liability, action, litigation, investigation or proceeding whatsoever (whether or not such indemnified person is a party thereto) whether threatened or commenced and in connection with the enforcement of this provision with respect to any of the above as such expenses are incurred, except with respect to the Registration Statement or such Prospectus insofar as any such loss, damage, expense, liability or claim arises out of or is based upon any untrue statement or alleged untrue statement of a material fact included in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager through such Manager to the Partnership expressly for use in the Registration Statement or such Prospectus in connection with such information, which material fact was not included in such information and which material fact was necessary in order to make the statements in such information, in the case of such Prospectus, in the light of the circumstances under which they were made, not misleading.

(b) Each Manager, severally and not jointly, shall indemnify, defend and hold harmless each Partnership Party and each of their respective directors and officers who signed the Registration Statement and any person who controls such Partnership Party, as applicable, within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and the successors and assigns of all of the foregoing persons, from and against any loss, damage, expense, liability or claim (including the reasonable cost of investigation) which, jointly or severally, the Partnership Parties or any such person may incur under the Securities Act, the Exchange Act, the common law or otherwise, insofar as such loss, damage, expense, liability or claim arises out of or is based upon (i) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager

furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, the Registration Statement (or in the Registration Statement as amended by any post-effective amendment thereof by the Partnership), or arises out of or is based upon any omission or alleged omission to state a material fact in such Registration Statement in connection with such information, which material fact was required to be stated in such Registration Statement or was necessary to make such information not misleading or (ii) any untrue statement or alleged untrue statement of a material fact contained in, and in conformity with information concerning such Manager furnished in writing by or on behalf of such Manager to the Partnership expressly for use in, any Preliminary Prospectus, any Prospectus Supplement, the Prospectus or any Issuer Free Writing Prospectus, or arises out of or is based upon any omission or alleged omission to state a material fact in the Pricing Disclosure Package, the Prospectus or any Issuer Free Writing Prospectus in connection with such information, which material fact was necessary in order to make the statements in such information, in the light of the circumstances under which they were made, not misleading.

(c) If any action, suit or proceeding (each, a “Proceeding”) is brought against a person (an “indemnified party”) in respect of which indemnity may be sought against the Partnership Parties or a Manager (as applicable, the “indemnifying party”) pursuant to subsection (a) or (b), respectively, of this Section 7, such indemnified party shall promptly notify such indemnifying party in writing of the institution of such Proceeding and such indemnifying party shall assume the defense of such Proceeding, including the employment of counsel reasonably satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party) and payment of all fees and expenses, whereupon the indemnifying party will not be liable to such indemnified party under this Section 7 for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation; provided, however, that the failure to so notify such indemnifying party shall not relieve such indemnifying party from any liability which such indemnifying party may have to any indemnified party or otherwise, except to the extent that the indemnifying party has been materially prejudiced (through the forfeiture of substantive rights or defenses) by such failure, but shall not relieve the indemnifying party from its obligation to provide reimbursement and contribution except to the extent so prejudiced. If such indemnified party shall have been advised by counsel that there are one or more defenses available to it that are in conflict with those available to the indemnifying party (in which case the indemnifying party shall not have the right to direct the defense of such action on behalf of the indemnified party), the payment of all fees and expenses of such indemnified party’s counsel shall be borne by the indemnifying party; provided, however, that such indemnifying party shall not be liable for the fees and expenses of more than one separate counsel (in addition to any local counsel) in any one Proceeding or series of related Proceedings in the same jurisdiction representing the indemnified parties who are parties to such Proceeding. The indemnifying party shall not be liable for any settlement of any Proceeding effected without its written consent but, if settled with its written consent, such indemnifying party agrees to indemnify and hold harmless the indemnified party or parties from and against any loss or liability by reason of such settlement. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have assumed control of the defense as contemplated by the second sentence of this Section 7(c), then the indemnifying party agrees that it shall be liable for any settlement of any Proceeding effected without its written consent if (i) such settlement is entered into more than 60 business days after receipt by such indemnifying party of the aforesaid request, (ii) such indemnifying

party shall not have fully reimbursed the indemnified party in accordance with such request prior to the date of such settlement and (iii) such indemnified party shall have given the indemnifying party at least 30 days’ prior notice of its intention to settle. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened Proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such Proceeding and does not include an admission of fault or culpability or a failure to act by or on behalf of such indemnified party.

(d) If the indemnification provided for in this Section 7 is unavailable to an indemnified party under Section 7(a) or 7(b) or insufficient to hold an indemnified party harmless in respect of any losses, damages, expenses, liabilities or claims, referred to therein, then each applicable indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, damages, expenses, liabilities or claims (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership Parties, on the one hand, and the Managers, on the other, from the offering of the Offered Units or (ii) if the allocation provided by clause (i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) above but also the relative fault of the Partnership Parties, on the one hand, and the Managers, on the other, in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Partnership Parties, on the one hand, and the Managers, on the other, shall be deemed to be in the same respective proportions as the total net proceeds received by the Partnership (net of underwriting discounts and commissions but before deducting expenses) from the offering of the Offered Units purchased under this Agreement as determined by this Agreement or any Applicable Terms Agreement, on the one hand, and the total underwriting discounts and commissions received by the Managers with respect to the Offered Units purchased under this Agreement or such Applicable Terms Agreement, on the other hand. The relative fault of the Partnership Parties on the one hand and of the Managers on the other hand shall be determined by reference to, among other things, whether the untrue statement or alleged untrue statement of a material fact or omission or alleged omission relates to information supplied by the Partnership Parties on the one hand or by the Managers on the other hand, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such statement or omission. The amount paid or payable by a party as a result of the losses, damages, expenses, liabilities and claims referred to in this subsection shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with investigating, preparing to defend or defending any Proceeding.

(e) The Partnership Parties and the Managers agree that it would not be just and equitable if contributions pursuant to this Section 7(d) were to be determined by pro rata allocation (even if the Managers were treated as one entity for such purpose) or by any other method of allocation which does not take into account the equitable considerations referred to in subsection (c) above. Notwithstanding the provisions of this Section 7(d), no Manager shall be required to contribute any amount in excess of the amount by which the total price at which the Units underwritten by such Underwriter and distributed to the public were offered to the public exceeds the amount of any damage which such Underwriter has otherwise been required to pay

by reason of such untrue statement or alleged untrue statement or omission or alleged omission and (ii) in no case shall the Partnership be required to contribute any amount in excess of the aggregate net proceeds received by the Partnership (after deducting underwriting discounts and commissions but before deducting offering expenses), from the offering of the Offered Units purchased by such Manager hereunder. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Managers’ obligations to contribute pursuant to this Section 7(d) are several in proportion to their respective underwriting commitments and not joint.

(f) The indemnity and contribution agreements contained in this Section 7 and the covenants, warranties and representations of the Partnership Parties contained in this Agreement shall remain in full force and effect regardless of any investigation made by or on behalf of any Manager and its partners, directors, officers, employees, agents or members or any person (including each partner, officer, director, employee or member of such person) who controls any Manager within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act and any affiliate of such Manager by or on behalf of the Partnership Parties, their respective directors, employees or officers or any person who controls the Partnership Parties within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, and shall survive any termination of this Agreement or the sale and delivery of the Offered Units. Each Partnership Party and each Manager agree promptly to notify each other of the commencement of any Proceeding against it and, in the case of the Partnership Parties, against any of their respective officers, employees or directors in connection with the offering and sale of the Offered Units, or in connection with the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus.

8. Termination.

(a) The Partnership shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Units in its sole discretion at any time. Any such termination shall be without liability of any party to any other party except that (i) if Offered Units have been sold through the Managers for the Partnership, then Section 4(u) shall remain in full force and effect, (ii) with respect to any pending sale, through the Managers for the Partnership, the obligations of the Partnership, including in respect of compensation of the Managers, shall remain in full force and effect notwithstanding the termination and (iii) the provisions of Sections 2, 5, 7, 9, 10, 11, 12, 13 and 17 of this Agreement shall remain in full force and effect notwithstanding such termination.

(b) Each Manager shall have the right, by giving written notice as hereinafter specified, to terminate the provisions of this Agreement relating to the solicitation of offers to purchase the Offered Units in their sole discretion at any time.

(c) In the case of any purchase of Offered Units by any Manager pursuant to a Terms Agreement, the obligations of the Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of the Manager, by notice given to the Partnership prior to the Time of Delivery relating to such Offered Units, 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 NYSE or trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (ii) a banking moratorium shall have been declared either by Federal or New York State authorities or (iii) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war, or other calamity or crisis the effect of which on financial markets is such as to make it, in the sole judgment of the Manager, impractical or inadvisable to proceed with the offering or delivery of the Offered Units as contemplated by the Prospectus (exclusive of any amendment or supplement thereto)

(d) This Agreement shall remain in full force and effect unless terminated pursuant to Sections 8(a), (b) or (c) above or otherwise by mutual agreement of the parties; provided that any such termination by mutual agreement shall in all cases be deemed to provide that Sections 2, 5, 7 and 9 shall remain in full force and effect.

(e) Any termination of this Agreement shall be effective on the date specified in such notice of termination; provided that such termination shall not be effective until the close of business on the date of receipt of such notice by any Manager or the Partnership, as the case may be.

[ ] shall have the right to purchase from the Partnership all or a portion of the Additional Units as may be necessary to cover over-allotments made in connection with the offering of the Purchased Units, at the same purchase price per unit to be paid by the Manager to the Partnership for the Purchased Units. This option may be exercised by the Manager at any time (but not more than once) on or before the thirtieth day following the date hereof, by written notice to the Partnership. Such notice shall set forth the aggregate number of Additional Units as to which the option is being exercised, and the date and time when the Additional Units are to be delivered (such date and time being herein referred to as the “Option Closing Date”); provided, however, that the Option Closing Date shall not be earlier than the Time of Delivery (as set forth in the Schedule I hereto) nor earlier than the second business day after the date on which the option shall have been exercised nor later than the fifth business day after the date on which the option shall have been exercised. Payment of the purchase price for the Additional Units shall be made at the Option Closing Date in the same manner and at the same office as the payment for the Purchased Units.

Each of the provisions of the Equity Distribution Agreement not specifically related to the solicitation by the Manager, as agent of the Partnership, of offers to purchase securities is incorporated herein by reference in its entirety, and shall be deemed to be part of this Terms Agreement to the same extent as if such provisions had been set forth in full herein. Each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Terms Agreement, the Time of Delivery [and any Option Closing Date], except that each representation and warranty in Section 2 of the Equity Distribution Agreement which makes reference to the Prospectus (as therein defined) shall be deemed to be a representation and the Prospectus dated August 2, 2013 that relates to the Purchased Units (the “Purchased Units Prospectus”), and also a representation and warranty as of the date of this Terms Agreement and the Time of Delivery [and any Option Closing Date] with respect to the Purchased Units Prospectus.

Annex I, Page 1

[An amendment to the Registration Statement (as defined in the Equity Distribution Agreement), or a supplement to the Prospectus, as the case may be, relating to the Purchased Units [and the Additional Units], in the form heretofore delivered to the Manager is now proposed to be filed with the Securities and Exchange Commission.]

Subject to the terms and conditions set forth herein and in the Equity Distribution Agreement which are incorporated herein by reference, the Partnership agrees to issue and sell to the Manager and the latter agrees to purchase from the Partnership the number of Purchased Units at the time and place and at the purchase price set forth in Schedule I hereto.
