Morgan Securities LLC, Mizuho Securities USA Inc., Merrill Lynch, Pierce, Fenner & Smith Incorporated, BNP Paribas Securities Corp., Citigroup Global Markets Inc., Scotia Capital (USA) Inc. and UBS Securities LLC (each a “Manager” and collectively, 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 (“Common Units”), having an aggregate gross sales price to the public of up to $150,000,000 (the “Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 of this Agreement. For the avoidance of doubt, the term “Units” as used in this Agreement refers only to the Common Units to be sold pursuant to this Agreement. The Units are further described in the Prospectus referred to herein. For purposes of selling the Units through the Managers, the Partnership hereby appoints the Managers as exclusive agents of the Partnership with respect to the issuance and sale of the Units from time to time by the Partnership pursuant to this Agreement and the Managers agree to use their commercially reasonable efforts to sell the Units in the manner and subject to the terms and conditions described in this Agreement. The Partnership agrees that whenever it determines to sell Units directly to any Manager as principal, or otherwise wishes to negotiate specific terms and provisions with a Manager related to sales of Units hereunder, it will enter into a separate agreement (each, a “Terms Agreement”) in substantially the form of Exhibit A hereto, relating to such sale in accordance with Section 3 of this Agreement. Certain terms used herein are defined in Section 19 hereof.

The Partnership and Dominion Midstream GP, LLC, a Delaware limited liability company and the general partner of the Partnership (the “General Partner”), are collectively referred to herein as the “Partnership Parties.”

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

(a) Registration. The Partnership meets the requirements for use of Form S-3 under the Act and has prepared and filed with the Commission a registration statement on Form S-3 (File Number: 333-211161), including a related Base Prospectus, for registration under the Act of the offering and sale of Common Units, including the Units, and such Registration Statement, including any amendments thereto filed prior to the Execution Time, has become effective. The Partnership has filed with the Commission the Prospectus Supplement relating to the Units in accordance with Rule 424(b). As filed, the Prospectus contains all information required by the Act and the rules thereunder, and, except to the extent the Managers agree in writing to a modification, shall be in all substantive respects in the form furnished to the Managers prior to the Execution Time or prior to any such time this representation is repeated or deemed to be made. The Registration Statement, at the Execution Time, at each such time this representation is repeated or deemed to be made, and at all times during which a prospectus is required by the Act to be delivered (whether physically, deemed to be delivered pursuant to Rule 153, or through compliance with Rule 172 or any similar rule) in connection with any offer or sale of 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.

If the Partnership files a successor registration statement with respect to the Units, after 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 included therein by reference, included in any such registration statement at the time such registration statement became effective.

(b) No Stop Order.

(e) No Material Misstatements or Omissions in the Prospectus. On the date of any filing pursuant to Rule 424(b), at the Execution Time, at each Applicable Time, on each Settlement Date and at all times during which a prospectus is required by the Act to be delivered (whether physically, deemed to be delivered pursuant to Rule 153, or through compliance with Rule 172 or any similar rule) in connection with any offer or sale of Units, the Prospectus complied and will comply in all material respects with the applicable requirements of the Act and the Exchange Act and the respective rules thereunder and 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 that no representation or warranty is made as to information included in or omitted from the Prospectus in reliance upon and in conformity with written information furnished to the Partnership by or on behalf of the Managers specifically for inclusion therein, which information is specified in Section 7(b).

3. Sale and Delivery of Units.

(a) Sale of Units by the Managers, as Sales Agents. Subject to the terms and conditions and in reliance upon the representations and warranties herein set forth, the Partnership agrees to issue and sell 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 agent for the Partnership, the Units on the following terms.

(i) The Units are to be sold by one of the Managers as shall be agreed to by the Partnership and such Manager on any day that (A) is a Trading Day for the NYSE (other than a day on which the NYSE is scheduled to close prior to its regular weekday closing time), (B) the Partnership, through any of the individuals listed as “Authorized Representatives” on Schedule II hereto, as the same may be amended or supplemented by the Partnership in its sole discretion upon advance notice to the Managers, has instructed such Manager by electronic mail or telephone (and in the case of 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 (i) the maximum amount of the 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), (ii) the minimum price per Unit at which such Units may be sold and (iii) the compensation payable to such Manager for such sales pursuant to Section 3(a)(v), which compensation shall have been discussed and agreed to by the Partnership and such Manager. Subject to the terms and conditions hereof, such Manager shall use its commercially reasonable efforts to sell on a particular day all of the Units designated for sale by the Partnership on such day. The gross sales price of the Units sold under this Section 3(a) shall be the market price for the Partnership’s Common Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Units, as otherwise agreed to by the Partnership and such Manager, or as otherwise instructed by the Partnership. For the avoidance of doubt, the Partnership shall submit instructions to sell Units to only one Manager, if any, on any single Trading Day. For the purposes hereof, “Trading Day” means any day on which the Common Units are purchased and sold on the principal market on which the Common Units are listed or quoted.

(ii) The Partnership acknowledges and agrees that (A) there can be no assurance that the Managers will be successful in selling the 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 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 Units as required under this Agreement, and (C) no Manager shall be under any obligation to purchase Units on a principal basis pursuant to this Agreement, except as otherwise specifically agreed by such Manager and the Partnership.

(iii) The Partnership shall not authorize the issuance and sale of, and the relevant Manager shall not be obligated to use its commercially reasonable efforts to sell, any Units at a price lower than the minimum price therefor designated from time to time by the Board of Directors of the General Partner (the “Board”), a duly authorized committee thereof, or any individual to whom such authority has been duly and properly delegated by the Board or a duly authorized committee thereof, and notified to such Manager in writing. The Partnership or any Manager may, upon notice to the other party hereto by electronic mail or telephone (and in the case of telephone, confirmed promptly by electronic mail), suspend or terminate the offering of the 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 Units sold hereunder prior to the giving of such notice.

(iv) Each Manager hereby covenants and agrees not to make any sales of the Units on behalf of the Partnership pursuant to this Section 3(a), other than (A)(1) by means of ordinary brokers’ transactions between members of the NYSE, any other national securities exchange or facility thereof, a trading facility of a national securities association, or an alternative trading system that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 under the Act, (2) to or through a market maker or (3) directly on or through an electronic communication network, a “dark pool” or any similar market venue and (B) such other sales of the Units on behalf of the Partnership in its capacity as agent of the Partnership as shall be permitted by law and agreed to by the Partnership and such Manager.

(v) The compensation to each Manager for sales of the 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 Units sold pursuant to this Section 3(a), as mutually agreed to in writing by the Partnership and such Manager, and payable as described in the succeeding subsection (vi) below. The foregoing rate of compensation shall not apply when the Manager acts as principal, in which case the Partnership may sell Units to such Manager as principal at a price mutually agreed upon at the relevant Applicable Time pursuant to a Terms Agreement. The gross proceeds less such Manager’s commission shall constitute the net proceeds to the Partnership (the “Net Proceeds”) for such Units. Payment of the Net Proceeds after further deduction for any transaction fees imposed by any governmental or self-regulatory organization in respect of such sales (the “Transaction Fees”) for Units sold by the Partnership on any Settlement Date shall be made to the Partnership by federal funds wire transfer to the account of the Partnership against delivery of such Units to such Manager’s account, or an account of such Manager’s designee, at The Depository Trust Company (“DTC”).

(vi) The Manager acting as sales agent hereunder 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 on which Units with respect to which such Manager is acting as sales agent are sold under this Section 3(a) setting forth the number of the Units sold on such day, the aggregate gross sales proceeds and the Net Proceeds to the Partnership, 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 Units pursuant to this Section 3(a) will generally 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 Units sold through a Manager for settlement on such date shall be issued and delivered by the Partnership to such Manager against payment of the Net Proceeds for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units to such Manager’s account, or an account of such Manager’s designee, at 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 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 a Manager acting as sales agent hereunder breaches this Agreement by failing to deliver the Net Proceeds less any Transaction Fees to the Partnership on any Settlement Date for the Units delivered by the Partnership to such Manager, such Manager will pay the Partnership interest based on the effective overnight federal funds rate on such unpaid amount less any compensation due to such Manager.

(viii) At each Applicable Time, each Time of Delivery, each Settlement Date and each 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, but modified to relate to the Registration Statement, the Prospectus and the documents incorporated by reference therein, in each case as amended or supplemented as of such date. Any obligation of a Manager to use its commercially reasonable efforts to sell the Units on behalf of the Partnership shall be subject to the continuing accuracy of the representations and warranties of the Partnership herein (as modified in the manner described above), 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) Sale of Units by a Manager, as Principal. If the Partnership wishes to issue and sell the Units pursuant to this Agreement but other than as set forth in Section 3(a) of this Agreement (each, a “Placement”), it will notify a Manager of the proposed terms of such Placement. If such Manager, 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 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 unless and until the Partnership and such Manager 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) Terms Agreement. Each sale of the Units to a 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 Units to, and the purchase thereof by, such Manager. A Terms Agreement may also specify certain provisions relating to the reoffering of such Units by such Manager. The commitment of such Manager to purchase the 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, but modified in the manner described in Section 3(a)(viii) hereof, and shall be subject to the terms and conditions herein set forth. Each Terms Agreement shall specify the number of the Units to be purchased by such Manager pursuant thereto, the price to be paid to the Partnership for such Units, any provisions relating to rights of, and default by, underwriters acting together with such Manager in the reoffering of the 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 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. For the avoidance of doubt, if the Partnership engages a Manager for a sale of Units other than as set forth in Section 3(a) and 3(b) hereof or if such sale would constitute a “distribution” within the meaning of Rule 100 of Regulation M under the Exchange Act or a “block” within the meaning of Rule 10b-18(a)(5) under the Exchange Act, the Partnership will provide the Manager, at the Manager’s request and upon reasonable advance notice to the Partnership, on or prior to the Settlement Date the opinions of counsel, accountants’ letters and officer’s certificates pursuant to Section 6 hereof, each dated the Settlement Date, and such other documents and information as the Manager shall reasonably request, and the Partnership and the Manager will agree to compensation with respect to such transaction.

(d) Limitations on Number and Amount of Units Sold. Under no circumstances shall the number and aggregate amount of the Units sold pursuant to this Agreement and any Terms Agreement exceed (i) the aggregate amount set forth in Section 1, (ii) the number of Common Units available for issuance under the currently effective Registration Statement or (iii) the number and aggregate amount of the Units authorized from time to time to be issued and sold under this Agreement by the Board, or a duly authorized committee or authorized individual thereof, and notified to such Manager in writing. Under no circumstances shall the price of the Units sold pursuant to this Agreement and any Terms Agreement be lower than the minimum price authorized from time to time to be issued and sold under this Agreement or any Terms Agreement by the Board, or a duly authorized committee or authorized individual thereof, and notified to such Manager in writing.

(e) Regulation M Exemption. If any of the Partnership Parties or Managers has reason to believe that the exemptive provisions set forth in Rule 101(c)(1) of Regulation M under the Exchange Act are not satisfied with respect to the Units, it shall promptly notify the other party and sales of the 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) Material Non-Public Information. Notwithstanding any other provision of this Agreement, (i) no sales of Units shall take place, and the Partnership shall not request the sales of any Units during any period in which the Partnership is in possession of material non-public information, and (ii) except as provided in Section 3(g) of this Agreement, the Partnership shall not offer, sell or deliver, or request the offer or sale, of any Units pursuant to this Agreement and, by notice to the Managers given by telephone (confirmed promptly by email), shall cancel any instructions for the offer or sale of any Units, and the Manager shall not be obligated to offer or sell any Units at any time from and including the date on which the Partnership shall issue a press release containing, or shall otherwise publicly announce, its earnings, revenues or other results of operations (an “Earnings Announcement”) through and including the time that is 24 hours after the time that the Partnership files (a “Filing Time”) a Quarterly Report on Form 10-Q or an Annual Report on Form 10-K that includes consolidated financial statements as of and for the same period or periods, as the case may be, covered by such Earnings Announcement (such period referred to herein as a “Quarterly Blackout Period”).

(g) Sales During Quarterly Blackout Periods. Notwithstanding Section 3(f) above, if the Partnership wishes to offer or sell Units to a Manager as sales agent at any time during a Quarterly Blackout Period, the Partnership shall (i) prepare and deliver to such Manager (with a copy to counsel for the Managers) a draft of a

Current Report on Form 8-K, which shall include substantially the same financial and related information (together with management’s discussion and analysis thereof) that was included in such Earnings Announcement (other than any earnings projections and similar forward-looking data and officer’s quotations) (each, an “Earnings 8-K”), in form and substance reasonably satisfactory to such Manager, and, prior to its filing, obtain the written consent of such Manager to such filing (which consent shall not be unreasonably withheld, conditioned or delayed), (ii) provide the Managers with the opinions and letters of counsel to the Managers, officers’ certificate and accountants’ letter called for by Sections 6(b), (c), (d) and (e), respectively, hereof, (iii) afford such Manager the opportunity to conduct a due diligence review in accordance with Section 6(i) hereof prior to filing such Earnings 8-K and (iv) file (as opposed to “furnish”) such Earnings 8-K with the Commission, and the provisions of clause (ii) of Section 3(f) shall not be applicable for the period from and after the time at which the foregoing conditions shall have been satisfied (or, if later, the time that is 24 hours after the time that the relevant Earnings Announcement was first publicly released) through and including the time that is 24 hours after the Filing Time of the relevant Quarterly Report on Form 10-Q or Annual Report on Form 10-K under the Exchange Act, as the case may be. For purposes of clarity, the parties hereto agree that (A) the delivery of any officer’s certificate, opinion or letter of counsel or accountants’ letter pursuant to this Section 3(g) shall not relieve the Partnership from any of its obligations under this Agreement with respect to any Quarterly Report on Form 10-Q or Annual Report on Form 10-K, as the case may be, including, without limitation, the obligation to deliver the opinions and letters of counsel, officer’s certificates and accountants’ letter, as provided in Sections 6(b), (c), (d) and (e), respectively, hereof, and (B) this Section 3(g) shall in no way affect or limit the operation of clause (i) of Section 3(f), which shall have independent application.

4. Agreements. The Partnership covenants and agrees with the Managers that:

(a) Filing of Amendment or Supplement. During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172 or any similar rule) to be delivered under the Act, the Partnership will not file any (i) amendment to the Registration Statement, or (ii) supplement to the Prospectus (other than any amendment or supplement which does not relate to the sale of the Units and not including any reports or documents and any preliminary or definitive proxy or information statement required to be filed by the Partnership with the Commission in order to comply with the Exchange Act), unless the Partnership has furnished to the Managers a copy for its review prior to filing and will not file any such proposed amendment, supplement or Registration Statement to which any Manager reasonably objects, unless the Partnership shall have determined based upon the advice of counsel that such amendment, supplement or filing is required by law. 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 each Manager (i) when the Prospectus, and any supplement thereto, shall have been filed (if required) with the Commission pursuant to Rule 424(b), (ii) when, during any period when the delivery of a prospectus (whether physically, deemed to be delivered pursuant to Rule 153 or through compliance with Rule 172 or any similar rule) is required under the Act in connection with the offering or sale of the 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 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 or pursuant to Section 8A of the Act and (v) of the receipt by the Partnership of any notification with respect to the suspension of the qualification of the Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its commercially reasonable 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 commercially reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) Notice of Material Changes. 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 Prospectus 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 each Manager so that any use of the Prospectus may cease until it is amended or supplemented; (ii) amend or supplement the Prospectus to correct such statement or omission; and (iii) supply any amendment or supplement to each Manager in such quantities as such Manager may reasonably request.

(c) Amendment of Registration Statement or Supplement of Prospectus. During any period when the delivery of a prospectus relating to the Units is required (including in circumstances where such requirement may be satisfied pursuant to Rule 172 or any similar rule) to be delivered under the 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 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 each Manager of any such event; (ii) prepare and file with the Commission, subject to the second 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 commercially reasonable 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 each Manager in such quantities as such Manager may reasonably request.

(d) Reports to Securityholders. In accordance with Section 11(a) of the Act and Rule 158, the Partnership will make generally available to its security holders an earnings statement (which need not be audited) in reasonable detail covering the 12-month period beginning not later than the first day of the month next succeeding the month in which occurred the effective date (within the meaning of Rule 158) of the Registration Statement as soon as practicable after the end of such period.

(e) Signed Copies of the Registration Statement and Copies of the Prospectus. The Partnership will furnish to each Manager and counsel for the Managers, upon request and without charge, one copy of the executed Registration Statement (including exhibits thereto) and, so long as delivery of a prospectus by such Manager or dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172 or any similar rule), as many copies of the Prospectus and any supplement thereto as such Manager may reasonably request.

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

(g) No Issuer Free Writing Prospectus. Each of the Partnership and the Managers agree that it has not made and will not make any offer relating to the 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.

(h) Limitations on Sale of Common Units. If sales of the Units have been made but not settled, or the Partnership has had outstanding with the Managers any instructions to sell the Units, in either case, within the prior three Business Days, the Partnership will not offer, sell, contract to sell, pledge, or otherwise dispose of, or enter into any transaction which is designed to, or might reasonably be expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement or otherwise) by the Partnership or any affiliate of the Partnership or any person in privity with the Partnership or any affiliate of the Partnership, directly or indirectly, including the filing (or participation in the filing) of a registration statement with the Commission in respect of, or establish or increase a put equivalent position or liquidate or decrease a call equivalent position within the meaning of Section 16 of the Exchange Act, any Common Units or any securities convertible into, or exercisable, or exchangeable for, Common Units, or publicly announce an intention to effect any such transaction

without (i) giving such Manager at least three Business Days’ prior written notice specifying the nature of the proposed transaction and the date of such proposed transaction and (ii) such Manager suspending acting under this Agreement for such period of time requested by the Partnership or as deemed appropriate by such Manager in light of the proposed transaction; provided, however, that (i) the Partnership may issue and sell Common Units pursuant to this Agreement or any Terms Agreement, (ii) the Partnership may issue and sell Common Units pursuant to any employee benefit plan of the Partnership in effect on or prior to the Execution Time, (iii) the Partnership may issue Common Units pursuant to any employee stock option plan, stock ownership plan or dividend reinvestment plan of the Partnership in effect at the Execution Time and (iv) the Partnership may issue Common Units issuable upon the conversion of securities or the exercise of warrants outstanding at the Execution Time.

(i) Market Stabilization. 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 Common Units to facilitate the sale or resale of the 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 Units.

(j) Notifications to Managers.

(xvi) Compliance with the Act. The Registration Statement (including the information deemed to be a part thereof pursuant to Rule 430A under the Act), as of the latest Effective Date and the Prospectus, when filed with the Commission pursuant to Rule 424(b) and on the date hereof, each appeared on its face to be appropriately responsive in all material respects to the applicable form requirements for registration statement on Form S-3 under the Act and the rules and regulations thereunder, it being understood, however, that such counsel need not express a view with respect to Regulation S-T or the financial statements, schedules or other financial data included in, or omitted from, the Registration Statement or the Prospectus.

(A) the Registration Statement, as of the 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;

(B) the Prospectus, as of its date or as of the Applicable Time and as the date of the opinion, 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;

(d) The Partnership shall have furnished to each Manager (or, in the case of a Representation Date of the type described in Section 4(k)(iii), the relevant Manager party to such Terms Agreement), within two (2) Trading Days of every Representation Date, a certificate of the Partnership, signed on behalf of the Partnership by an executive officer, the Treasurer or the General Counsel of the General Partner, dated as of the date such certificate is delivered, to the effect that the signer of such certificate has carefully examined the Registration Statement and the Prospectus and any amendment or supplement thereto and this Agreement and that:

(i) the representations and warranties of the Partnership Parties in this Agreement are true and correct on and as of such date with the same effect as if made on such date and the Partnership Parties have complied with all the agreements and satisfied all the conditions on its part to be performed or satisfied at or prior to such 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 Parties’ knowledge, threatened; and

(f) Between the Execution Time and any Time of Delivery, there shall not have been (i) any change or decrease specified in the letter or letters referred to in paragraph (e) 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 or properties of the Partnership Entities 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 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 Manager, so material and adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Registration Statement (exclusive of any amendment thereof) and the Prospectus (exclusive of any amendment or supplement thereto).

(g) FINRA shall not have raised any objection with respect to the fairness and reasonableness of the terms and arrangements under this Agreement or any Terms Agreement.

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 any Manager and counsel for the Managers, this Agreement, as it relates to such Manager, and all obligations of such Manager hereunder may be canceled at, or at any time prior to, any Settlement Date or Time of Delivery, as applicable, by such Manager. Notice of such cancellation shall be given to the Partnership in writing or by telephone or facsimile confirmed in writing. Notwithstanding any other provision of this Agreement, the Partnership shall not offer, sell or deliver, or request the offer or sale, of any Units pursuant to this Agreement following any Representation Date until the Partnership has provided the Managers with the opinions and letters of counsel, the officers’ certificate and accountants’ letter specified in Sections 6(b), (c), (d) and (e), hereof and afforded the Managers the opportunity to conduct a due diligence review in accordance with Section 6(i) hereof.

7. Indemnification and Contribution.

(a) The Partnership Parties agree, jointly and severally, to indemnify and hold harmless the Managers, the directors, officers, employees and agents of the Managers and each person who controls any Manager within the meaning of either the Act or the Exchange Act against any and all losses, claims, damages, expenses 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, expenses 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, the Base Prospectus, the Prospectus Supplement, the Prospectus or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating, preparing for or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership Parties will not be liable in any such case to the extent that any such loss, claim, damage, expense 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 Parties by or on behalf of the Managers specifically for inclusion therein. This indemnity agreement will be in addition to any liability which the Partnership Parties may otherwise have.

(b) The Managers, severally and not jointly, agree to indemnify and hold harmless the Partnership Parties, each of the Partnership Parties’ directors and officers who sign the Registration Statement, and each person who controls the Partnership Parties within the meaning of either the Act or the Exchange Act, to the same extent as the foregoing indemnity from the Partnership Parties to each Manager, but only with reference to written information relating to a Manager furnished to the Partnership Parties by or on behalf of such Manager specifically for inclusion in the documents referred to in the foregoing indemnity, which information consists only of the name of the Managers. This indemnity agreement will be in addition to any liability which any Manager may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section 7 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 7, 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. An indemnifying party will not, (i) without the prior written consent of the indemnified parties (which consent shall not be unreasonably withheld), 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 includes an unconditional release of each indemnified party from all liability arising out of such claim, action, suit or proceeding and does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of any indemnified party or (ii) be liable for any settlement of such action without its written consent, except as otherwise permitted in the following sentence. If at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for fees and expenses of counsel, such indemnifying party agrees that it shall be liable for any settlement of the nature contemplated by Section 7(c) hereof effected without its written consent if (A) such settlement is entered into more than forty-five (45) days after receipt by such indemnifying party of the aforesaid request, (B) such indemnifying party shall have received notice of the terms of such settlement at least thirty (30) days prior to such settlement being entered into and (C) such indemnifying party shall not have reimbursed such indemnified party in accordance with such request or disputed in good faith the indemnified party’s entitlement to such reimbursement prior to the date of such settlement.

(d) In the event that the indemnity provided in paragraph (a) or (b) of this Section 7 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Partnership Parties and each Manager 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 Parties and the Managers may be subject in such proportion as is appropriate to reflect the relative fault of the Partnership Parties, on the one hand, and of the Managers, on the other, in connection with the statements or

omissions which resulted in such Losses; provided, however, that in no case shall the Managers be responsible for any amount in excess of the compensation to such Manager for sales of the Units hereunder. For the avoidance of doubt, the obligation of each Manager to contribute pursuant to this Section 7(d) shall be several and not joint. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Partnership Parties and the Managers severally shall contribute in such relative proportions as is appropriate to reflect not only such relative fault but also the relative benefits received by the Partnership Parties, on the one hand, and by any Manager, on the other, in connection with the offering of the Units as well as any other relevant equitable considerations. Benefits received by the Partnership Parties shall be deemed to be equal to the total net proceeds from the offering of the Units purchased under this Agreement (before deducting expenses) received by the Partnership Parties, as determined by this Agreement or any applicable Terms Agreement, and benefits received by the Managers shall be deemed to be equal to the total compensation received by such Managers with respect to the Units purchased under this Agreement, in each case as determined by this Agreement or any applicable Terms Agreement. 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 Parties on the one hand or by or on behalf of the Managers 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 Parties and each Manager agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 7, each person who controls a Manager within the meaning of either the Act or the Exchange Act and each director, officer, employee and agent of a Manager shall have the same rights to contribution as any Manager, and each person who controls the Partnership Parties within the meaning of either the Act or the Exchange Act, each officer of the Partnership Parties, who shall have signed the Registration Statement and each director of the Partnership Parties shall have the same rights to contribution as the Partnership Parties, subject in each case to the applicable terms and conditions of this paragraph (d) to collect such amounts from the Partnership Parties, except in the event that the Partnership Parties commence or become subject to any bankruptcy, liquidation, reorganization, moratorium or other proceeding providing protection from creditors generally.

(b) Each Manager shall have the right, by giving written notice as hereinafter specified, to terminate its own obligations under the provisions of this Agreement relating to the solicitation of offers to purchase the Units in its sole discretion at any time. Any such termination shall have no effect on the obligations of any other Manager under this Agreement and shall be without liability of any party to any other party except that the provisions of Sections 2, 5, 7, 9, 10, 11, 12, 13, 15 and 16 of this Agreement shall remain in full force and effect with respect to such Managers notwithstanding such termination.

(c) This Agreement shall remain in full force and effect until the earlier of (i) its termination pursuant to Section 8(a) above or otherwise by mutual agreement of all of the parties and (ii) the termination of the obligations of each Manager pursuant to Section 8(b) above; 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.

(d) 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 Parties, as the case may be. If such termination shall occur prior to the Settlement Date or Time of Delivery for any sale of the Units, such sale shall settle in accordance with the provisions of Section 3(a)(vii) of this Agreement.

(e) In the case of any purchase of Units by any Manager pursuant to a Terms Agreement, the obligations of such Manager pursuant to such Terms Agreement shall be subject to termination, in the absolute discretion of such Manager, by notice given to the Partnership Parties prior to the Time of Delivery relating to such 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, (ii) trading in securities generally on the NYSE shall have been suspended or limited or minimum prices shall have been established on such exchange, (iii) a banking moratorium shall have been declared either by federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred, 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 such Manager, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Prospectus.
