Securities USA Inc., Morgan Stanley & Co. LLC, Raymond James & Associates, Inc., Scotia Capital (USA) Inc., SMBC Nikko Securities America, Inc., SunTrust Robinson Humphrey, Inc. and UBS 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 (“Common Units”), having an aggregate gross sales price of up to $750,000,000 (the “Units”), from time to time during the term of this Agreement and on the terms set forth in Section 3 hereof. 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 the exclusive agents of the Partnership for the purpose of soliciting purchases of the Units from the Partnership pursuant to this Agreement and each Manager agrees to use its reasonable efforts to solicit purchases of the Units on the terms and subject to the conditions stated herein. The Partnership agrees that whenever it determines to sell 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 hereof. Certain terms used herein are defined in Section 20 hereof.

2. Representations and Warranties. The Partnership represents and warrants to, and agrees with, each Manager 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, as set forth below.

(a) Registration. The Partnership meets the requirements for use of Form S-3 under the Act. The Partnership has prepared and filed with the Commission a registration statement (File Number 333-207140) on Form S-3 (including a related Base Prospectus) for registration of the offering and sale of Common Units, including the Units, under the Act, and 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, 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 Supplement contains all information required by the Act and the rules thereunder and, except to the extent the Managers shall 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, met or will meet 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, which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Base Prospectus, the Prospectus Supplement or the Prospectus, as the case may be; and any reference herein to the terms “amend,” “amendment” or “supplement” with respect to the Registration Statement, the Base Prospectus, 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. If the Partnership files a successor registration statement with respect to the Units, 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. As used herein, the term “Incorporated Documents” means the documents that at the time are incorporated by reference in the Registration Statement, the Base Prospectus, the Prospectus Supplement or the Prospectus or any amendment or supplement thereto.

(b) No Material Misstatements or Omissions in Registration Statement. On each Effective Date, at the Execution Time, at each Applicable Time, at 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 Registration Statement 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 contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in order to make the statements therein not misleading; and on the date of any filing pursuant to Rule 424(b), 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 (together with any supplement thereto) 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 contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; provided, however, that the Partnership makes no representations or warranties as to any statement contained in or omitted from the Registration Statement or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information furnished in writing to the Partnership by any of the Managers specifically for use with respect to the Registration Statement or the Prospectus (or any supplement thereto), which information is specified in Section 19.

(c) Ineligible Issuer. For purposes of each offering of the Units pursuant to transactions under this Agreement that are not firm commitment underwritings, the Partnership will be an “ineligible issuer” (as defined in Rule 405 of the Act) as of each relevant eligibility determination date for purposes of Rules 164 and 433 under the Act.

(d) No Other Prospectus. Prior to the execution of this Agreement, the Partnership has not, directly or indirectly, offered or sold any Units by means of any “prospectus” (in each case within the meaning of the Act) or used any “prospectus” (in each case within the meaning of the Act) in connection with the offer or sale of Units, and from and after the execution of this Agreement, the Partnership will not, directly or indirectly, offer or sell any Units pursuant to this Agreement by means of any “prospectus” (within the meaning of the Act) or use any “prospectus” (within the meaning of the Act) in connection with any such offer or sale of the Units, other than the Prospectus, as amended or supplemented from time to time in accordance with the provisions of this Agreement; the Partnership has not, directly or indirectly, prepared, used or referred to any Issuer Free Writing Prospectus, as defined in Rule 433, in connection with offers or sales of Units pursuant to this Agreement.

(g) Market Stabilization. Except as stated in this Agreement, any Terms Agreement and the Prospectus, the Partnership has not taken, nor will it take, directly or indirectly, any action designed to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of the Common Units to facilitate the sale or resale of the Units.

3. Sale and Delivery of Units.

(a) Sale of Offered 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 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 on a daily basis or otherwise 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 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 hereof. The Partnership will designate 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) and the minimum price per Unit at which such Units may be sold. Subject to the terms and conditions hereof, such Manager shall use its reasonable efforts to sell on a particular day all of the Units designated for the 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 Units sold by such Manager under this Section 3(a) on the NYSE at the time of sale of such Units. For the avoidance of doubt, the Partnership shall submit instructions to sell 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 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 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) each Manager shall be under no 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 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 (the “Board”) of PAGP GP, 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 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. During any such period of suspension, the Partnership shall not be obligated to deliver (or cause to be delivered) any of the documents referred to in Sections 4(l), (m), (n), (o) or (q), be deemed to affirm any of the representations or warranties contained in this Agreement pursuant to Section 3(a)(viii) or Section 4(v) hereof, or be obligated to conduct any due diligence session as referred to in Section 4(r) until the termination of the suspension and the recommencement of the offering of the Units pursuant to this Agreement (which recommencement shall constitute a Representation Date, as defined in Section 4(l)). For the avoidance of doubt, any period during which the Partnership has not provided instructions with respect to the sale of Units pursuant to Section 3(a)(i) hereof, or any period during which such instruction provided thereunder has been properly revoked by the Partnership, shall not be deemed a suspension of the program under this Agreement.

(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) by means of ordinary brokers’ transactions between members of the NYSE that qualify for delivery of a Prospectus to the NYSE in accordance with Rule 153 and (B) such other sales of the 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 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) and payable as described in the succeeding subclause (vi) below. The foregoing rate of compensation shall not apply when such Manager acts as principal, in which case the

Partnership may sell 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 due to the Partnership for such 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 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 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 or on behalf of the Partnership to such Manager against payment of the aggregate gross sales proceeds less any Transaction Fees for the sale of such Units. Settlement for all such Units shall be effected by free delivery of the Units to such Manager’s or such Manager’s designee’s account at The Depository Trust & Clearing Corporation (“DTC”) in return for payments in same day funds delivered to the Partnership by federal funds wire transfer to the account designated by the Partnership. If the Partnership or its transfer agent shall default on the 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 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 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 due to such Manager.

(viii) At each Applicable Time, Settlement Date, and Representation Date (as defined in Section 4(l) hereof), 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 incorporate the disclosures contained in the Registration Statement and the Prospectus, in each case as amended or supplemented as of such date. Any obligation of any Manager to use its 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 hereof.

(b) Sale of Offered 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) hereof (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 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 hereof and any other information or documents required by such Manager.

(d) Limitations on Number and Amount of Offered 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, if any, authorized to be issued and sold under this Agreement by the Board, or a duly authorized committee thereof, and notified to each Manager in writing.

(e) Regulation M. If either party 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.

4. Agreements. The Partnership agrees with each Manager 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) to be delivered under the Act, the Partnership will advise the Managers promptly of any amendment or supplement to the Registration Statement or the Prospectus which is proposed to be filed (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) and to provide the Managers reasonable opportunity to review the same. 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, 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 relating to the Units shall have been filed with the Commission, (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 any Rule 462(b) Registration Statement relating to the Units, 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 Units for sale in any jurisdiction or the institution or threatening of any proceeding for such purpose. The Partnership will use its 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 reasonable efforts to have such amendment or new registration statement declared effective as soon as practicable.

(b) Notice of Ineligibility. If at any time when Units remain unsold by the Managers, the Partnership receives from the Commission a notice or otherwise ceases to be eligible to use Form S-3, the Partnership will promptly notify the Managers, and the Partnership will not give any Manager instructions to sell Units under this Agreement until such time as the Partnership is again eligible to use Form S-3 for such purpose.

(c) 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 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 or the circumstances then prevailing not misleading, the Partnership will (i) notify promptly the Managers 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.

(d) Material Misstatements or Omissions in 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) under the Act, if 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 the Managers 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 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.

(e) Reports to Security Holders. 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.

(f) Signed Copies of Registration Statement. The Partnership will make available to each Manager, without charge, signed copies of the Registration Statement and, so long as delivery of a prospectus by such Manager or a dealer may be required by the Act (including in circumstances where such requirement may be satisfied pursuant to Rule 172), as many copies of the Prospectus and any amendments or supplement thereto as such Manager may reasonably request. The Partnership will pay the expenses of printing or other production of all documents relating to the offering.

(g) Qualification. 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.

(h) 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.

(i) Limitations on Sale of Common Units. At any time that sales of the Units have been made but not settled or at any time the Partnership has outstanding with any Manager any instructions to sell the Units but such instructions have not been fulfilled or cancelled, the Partnership will not, without 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, (i) offer, sell, contract to sell, pledge or otherwise dispose of (or enter into any transaction that 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 of its controlled

affiliates), 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 with respect to, any Common Units or any securities that are convertible into, or exercisable or exchangeable for, or that represent the right to receive, Common Units or any securities that are senior to or pari passu with Common Units, or publicly announce an intention to effect any such transaction, or (ii) grant any options or warrants to purchase Common Units; provided, however, (A) the Partnership may issue the 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, employee unit option plan, unit ownership plan or dividend reinvestment plan of the Partnership (or adopted by a GP Entity) in effect at the Applicable Time; and (C) the Partnership may issue or deliver Common Units issuable upon the conversion, vesting or exercise of securities (including long-term incentive plan awards, options and warrants) outstanding at the Applicable Time. In the event that notice of a proposed sale is provided by the Partnership pursuant to this Section 4(i), such Manager may (and shall if requested by the Partnership) suspend activity under this program for such period of time as may be requested by the Partnership or as may be deemed appropriate by such Manager.

(j) Market Stabilization. Except as stated in this Agreement, any Terms Agreement and the Prospectus, the Partnership has not taken, nor will it (i) take, directly or indirectly, any action designed to or that might reasonably be expected to cause or result in stabilization or manipulation of the price of the Common Units to facilitate the sale or resale of the Units or (ii) sell, bid for, purchase or pay any person any compensation for soliciting purchases of the Units.

(k) Notifications to Managers. The Partnership will, at any time during the term of this Agreement, as supplemented from time to time, advise the Managers immediately after it shall have received notice or obtain knowledge thereof, of any information or fact that would alter or affect any opinion, certificate, letter and other document which has been previously provided to the Managers pursuant to Section 6 herein.

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

(iii) since the date of the most recent financial statements included in the Prospectus, there has not been any change, or any development involving a prospective change, in the partnership interests, capital stock, or long-term debt of the Partnership or any of its subsidiaries that would reasonably be expected to cause a Material Adverse Effect, or any change in the general affairs, management, financial position, results of operations, cash flows or working capital of the Partnership and its subsidiaries, whether

or not arising from transactions in the ordinary course of business, that would reasonably be expected to cause a Material Adverse Effect, other than as set forth in or contemplated by the Prospectus.

(c) The Partnership shall have requested and caused the Partnership Counsel to furnish to the Managers (or, in the case of a Representation Date of the type described in Section 4(l)(iii), the relevant Manager party to the Terms Agreement), on every date specified in Section 4(m) hereof, its opinion, dated as of such date and addressed to the Managers (or, in the case of a Representation Date of the type described in Section 4(l)(iii), the relevant Manager party to the Terms Agreement), in the form set forth in Annex II hereto.

(g) The Partnership shall have requested and caused the Accountants to have furnished to the Managers or, in the case of Section 4(q)(ii), the relevant Manager party to the Terms Agreement, on every date specified in Section 4(q) hereof and to the extent reasonably requested by the Managers or, in the case of Section 4(q)(ii), the relevant Manager party to the Terms Agreement, with advance notice to the Partnership in connection with any offering of the Units, letters (which may refer to letters previously delivered to the Managers or, in the case of Section 4(q)(ii), the relevant Manager party to the Terms Agreement) containing statements and information of the type ordinarily included in accountants’ “comfort letters” to underwriters with respect to the financial statements and certain financial information contained in the Registration Statement and the Prospectus, dated as of such date, in form and substance satisfactory to the Managers or, in the case of Section 4(q)(ii), the relevant Manager party to the Terms Agreement; provided that the cut-off date for the procedures performed by such accountants and described in such letters shall be a date not more than five days prior to the date of such letter.

7. Indemnification and Contribution.

(a) The Partnership agrees to indemnify and hold harmless each Manager, the directors, officers, employees and agents of each Manager, each affiliate of any Manager who has participated in the distribution of the Units, each broker-dealer affiliate of any Manager and each other affiliate of any Manager within the meaning of Rule 405 under the Act, and each person who controls any Manager within the meaning of Section 15 of the Act or Section 20 of the Exchange Act against any and all losses, claims, damages, liabilities or expenses, joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses arise out of, or are based upon any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or 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 (in the case of the Prospectus, in the light of the circumstances under which they were made) not misleading, and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Partnership will not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made in reliance upon and in conformity with written information furnished to the Partnership by any Manager specifically for use therein, which information is specified in Section 19. The foregoing indemnity will be in addition to any liability that the Partnership may otherwise have.

(b) If any action, suit or proceeding shall be brought against any Manager, the directors, officers, employees and agents of any Manager or any person controlling any Manager in respect of which indemnity may be sought against the Partnership, such Manager or such director, officer, employee, agent or controlling person shall promptly notify the Partnership in writing, and the Partnership shall assume the defense thereof, including the employment of counsel reasonably satisfactory to such indemnified party and payment of all reasonable fees and expenses. The failure to notify the indemnifying party shall not relieve it from liability that it may have to an indemnified party unless the indemnifying party is foreclosed by reason of such delay from asserting a defense otherwise available to it. Such Manager or any such director, officer, employee, agent or controlling person shall have the right to employ separate counsel in any such action, suit or proceeding and to participate in (but not control) the defense thereof, but the fees and expenses of such counsel shall be at the expense of such Manager or such director, officer, employee, agent or controlling person unless (i) the Partnership has agreed in writing to pay such fees and expenses, (ii) the Partnership has failed to assume the defense and employ counsel within a reasonable period of time in light of the circumstances or (iii) such indemnified party or parties shall have reasonably concluded, based on the advice of counsel, that there may be defenses available to it or them that are

different from, additional to or in conflict with those available to the Partnership (in which case the Partnership shall not have the right to direct the defense of such action, suit or proceeding on behalf of the indemnified party or parties), in any of which events the Partnership shall pay the reasonable fees and expenses of such counsel as such fees and expenses are incurred (it being understood, however, that the Partnership shall not be liable for the expenses of more than one separate counsel (in addition to any local counsel) in any one action, suit or proceeding or series of related actions, suits or proceedings in the same jurisdiction representing the indemnified parties who are parties to such action, suit or proceeding).

(c) Each Manager, severally and not jointly, agrees to indemnify and hold harmless the Partnership, PAGP GP’s directors and the officers of GP LLC who sign the Registration Statement, and any person who controls the Partnership within the meaning of Section 15 of the Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Partnership to each Manager, but only with respect to information furnished in writing by or on behalf of such Manager expressly for use in the Registration Statement or the Prospectus, or any amendment or supplement thereto, which information is specified in Section 19. If any action, suit or proceeding shall be brought against the Partnership, any of such directors and officers or any such controlling person based on the Registration Statement or the Prospectus, or any amendment or supplement thereto, and in respect of which indemnity may be sought against a Manager pursuant to this paragraph (c), such Manager shall have the rights and duties given to the Partnership by paragraph (b) above (except that if the Partnership shall have assumed the defense thereof such Manager shall not be required to do so, but may employ separate counsel therein and participate in (but not control) the defense thereof, but the fees and expenses of such counsel shall be at such Manager’s expense), and the Partnership, any of such directors and officers and any such controlling person shall have the rights and duties given to the Managers by paragraph (b) above. The foregoing indemnity agreement shall be in addition to any liability that each Manager may otherwise have.

(d) In the event that the indemnification provided for in this Section 7 is unavailable to an indemnified party under paragraph (a) or (c) hereof in respect of any losses, claims, damages, liabilities or expenses referred to therein, then an indemnifying party, in lieu of indemnifying such indemnified party, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages, liabilities or expenses (i) in such proportion as is appropriate to reflect the relative benefits received by the Partnership on the one hand and the Managers on the other hand from the offering of the 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 on the one hand and the Managers on the other in connection with the statements or omissions that resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Partnership on the one hand and the Managers on the other shall be deemed to be in the same relative proportions as the total net proceeds from the offering (before deducting expenses) received by the Partnership bear to the total discounts and commissions received by the Managers, in each case as determined by this Agreement or any applicable Terms Agreement. The relative fault of the Partnership on the one hand and the Managers on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Partnership or any affiliate of the Partnership on the one hand, or by the Managers on the other hand, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.

(e) The Partnership and the Managers agree that it would not be just and equitable if contribution pursuant to this Section 7 were determined by a pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in paragraph (d) above. The amount paid or payable by an indemnified party as a result of the losses, claims, damages, liabilities and expenses referred to in paragraph (d) above shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating any claim or defending any such action, suit or proceeding. Notwithstanding the provisions of this Section 7, no Manager shall be required to contribute any amount in excess of the amount by which the total price of the Units distributed to the public pursuant to this Agreement exceeds the amount of damages that such Manager has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.

(f) No indemnifying party shall (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 any findings of fact or admissions of fault or culpability as to the indemnified party, or (ii) be liable for any settlement of any such action effected without its written consent (which consent shall not be unreasonably withheld), but if settled with the consent of the indemnifying party or if there be a final judgment for the plaintiff in any such action, the indemnifying party agrees to indemnify and hold harmless any indemnified party from and against any loss or liability by reason of such settlement or judgment.

(g) Any losses, claims, damages, liabilities or expenses for which an indemnified party is entitled to indemnification or contribution under this Section 7 shall be paid by the indemnifying party to the indemnified party as such losses, claims, damages, liabilities or expenses are incurred. The indemnity and contribution agreements contained in this Section 7 and the covenants, representations and warranties of the Partnership set forth in this Agreement shall remain operative and in full force and effect, regardless of (i) any investigation made by or on behalf of any Manager or any person controlling any Manager, the Partnership or any of PAGP GP’s directors or GP LLC’s officers or any person controlling the Partnership, (ii) acceptance of any Units and payment therefore in accordance with the terms of this Agreement, and (iii) any termination of this Agreement.

A successor to any Manager or any person controlling any Manager, or to the Partnership or any of PAGP GP’s directors or GP LLC’s officers or any person controlling the Partnership shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 7.

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 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 Units have been sold through any Manager for the Partnership, then Section 4(v) shall remain in full force and effect, (ii) with respect to any pending sale, through such Manager 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 5, 7, 9, 10, 11, 12, 13 and 15 hereof 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 its own obligations under the provisions hereof relating to the solicitation of offers to purchase the Units in its sole discretion at any time. Subject to Section 8(a)(iii), 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 5, 7, 9, 10, 11, 12, 13 and 15 hereof shall remain in full force and effect 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 the termination of all Managers’ obligations pursuant to Section 8(b) 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 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, 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) hereof.

(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 prior to the Time of Delivery relating to such Units, if at any time prior to such delivery and payment (i) trading in the Common Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the NYSE, the NYSE MKT LLC or the Nasdaq National Market shall have been suspended or limited or minimum prices shall have been established, (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 such Manager, impractical or inadvisable to proceed with the offering or delivery of the Units as contemplated by the Prospectus (exclusive of any amendment or supplement thereto).

9. Representations and Indemnities to Survive. The respective agreements, representations, warranties, indemnities and other statements of the Partnership or its officers and of each Manager set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by the Managers or the Partnership or any of the officers, directors, employees, agents or controlling persons referred to in Section 7 hereof, and will survive delivery of and payment for the Units.
