The Issuers have not made any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives. The Issuers have retained in accordance with the Rules and Regulations all Issuer Free Writing Prospectuses that were not required to be filed pursuant to the Rules and Regulations.

All of the outstanding shares of capital stock or other equity interests of each Material Subsidiary (a) have been duly authorized and validly issued (in accordance with the agreement or certificate of limited partnership, limited liability company agreement, certificate of formation, certificate or articles of incorporation, bylaws or other similar organizational documents (in each case as in effect on the date hereof and as the same may be amended or restated prior to the Delivery Date) (the “Organizational Documents”) of such Material Subsidiary), are fully paid (in the case of an interest in a limited partnership or limited liability company, to the extent required under the Organizational Documents of such Material Subsidiary) and nonassessable (except (i) in the case of an interest in a Delaware limited partnership or Delaware limited liability company, as such nonassessability may be affected by Sections 17-607 and 17-804 of the Delaware Revised Uniform Limited Partnership Act (the “Delaware LP Act”) or Sections 18-607 and 18-804 of the Delaware LLC Act, as applicable, (ii) in the case of an interest in a limited partnership or limited liability company formed under the laws of another domestic state, as such nonassessability may be affected by similar provisions of such state’s limited partnership or limited liability company statute, as applicable, and (iii) in the case of an interest in an entity formed under the laws of a foreign jurisdiction, as such nonassessability may be affected by similar provisions of such jurisdiction’s corporate, partnership or limited liability company statute, if any, as applicable) and (b) are owned, directly or indirectly, by the Partnership, free and clear of all Liens.

(financial or other), business, prospects, properties, net worth or results of operations of the Plains Entities, taken as a whole, or of the happening of any event that makes any statement of a material fact made in the Registration Statement, the Pricing Disclosure Package or the Prospectus (as then amended or supplemented) untrue or that requires the making of any additions to or changes in the Registration Statement, the Pricing Disclosure Package or the Prospectus (as then amended or supplemented) in order to state a material fact required by the Securities Act or the regulations thereunder to be stated therein or necessary in order to make the statements therein (in the case of any Preliminary Prospectus or the Prospectus, in the light of the circumstances under which any such statements were made) not misleading, or of the necessity to amend or supplement the Prospectus (as then amended or supplemented) to comply with the Securities Act or any other applicable law. If at any time the Commission shall issue any stop order suspending the effectiveness of the Registration Statement, the Partnership will make every commercially reasonable effort to obtain the withdrawal of such order at the earliest possible time.

(c) Final Term Sheet and Issuer Free Writing Prospectuses. The Issuers agree to (i) prepare a final term sheet, containing a description of the final terms of the Notes and the offering thereof, in the form approved by the Representatives and attached as Schedule II hereto, and to file such term sheet pursuant to Rule 433 of the Rules and Regulations within the time required by such Rule and (ii) not to make any offer relating to the Notes that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives.

(d) Copies of Registration Statement. The Issuers will furnish to the Underwriters, without charge, (i) one copy of the manually signed copy of the registration statement corresponding to the Commission’s electronic data gathering, analysis and retrieval system (“EDGAR”) version filed with the Commission and of each amendment thereto, including financial statements and all exhibits to the registration statement, (ii) such number of conformed copies of the registration statement as originally filed and of each amendment thereto, but without exhibits, as the Underwriters or the Underwriters’ counsel may reasonably request, (iii) such number of copies of the Incorporated Documents, without exhibits, as the Underwriters may request, and (iv) such number of copies of the exhibits to the Incorporated Documents as the Underwriters may request.

(e) Filing of Amendment or Supplement. For such period as in the opinion of counsel for the Underwriters a prospectus is required by the Securities Act to be delivered in connection with sales by any Underwriter or dealer, the Issuers will not file any amendment to the Registration Statement, supplement to the Prospectus (or any other prospectus relating to the Notes filed pursuant to Rule 424(b) of the Rules and Regulations that differs from the Prospectus as filed pursuant to such Rule 424(b)), or any Preliminary Prospectus or Issuer Free Writing Prospectus of which the Representatives shall not previously have been advised or to which the Representatives shall have reasonably objected in writing after being so advised unless the Issuers shall have determined based upon the advice of counsel that such amendment, supplement or other filing is required by law; and the Issuers will promptly notify the Representatives after they shall have received notice thereof of the time when any amendment to the Registration Statement becomes effective or when any supplement to the Prospectus has been filed.

(f) Copies of Documents to the Underwriters. As soon after the Applicable Time as possible and thereafter from time to time for such period as in the opinion of counsel for the Underwriters a prospectus is required by the Securities Act to be delivered in connection with sales by any Underwriter or dealer, the Issuers will expeditiously deliver to each Underwriter and each dealer that the Underwriters may specify, without charge, as many copies of the Prospectus (and of any amendment or supplement thereto) as the Underwriters may reasonably request. At any time after nine months after the time of issuance of the Prospectus, upon request and without charge, the Issuers will deliver as many copies of an amended or supplemented Prospectus complying with Section 10(a)(3) of the Securities Act as the Underwriters may reasonably request, provided that a prospectus is required by the Securities Act to be delivered in connection with sales of Notes by any Underwriter or dealer. The Issuers consent to the use of the Prospectus (and of any amendment or supplement thereto) in accordance with the provisions of the Securities Act and with the securities or Blue Sky laws of the jurisdictions in which the Notes are offered by the Underwriters and by all dealers to whom Notes may be sold, both in connection with the offering and sale of the Notes and for such period of time thereafter as the Prospectus is required by the Securities Act to be delivered in connection with sales by any Underwriter or dealer. If during such period of time any event shall occur that in the judgment of the Issuers or in the opinion of counsel for the Underwriters and the Issuers is required to be set forth in the Prospectus (as then amended or supplemented) or should be set forth therein in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary to supplement or amend the Prospectus (or to file under the Exchange Act any document which, upon filing, becomes an Incorporated Document) to comply with the Securities Act or any other law, the Issuers will forthwith prepare and, subject to the provisions of paragraph (e) above, file with the Commission an appropriate supplement or amendment thereto (or to such document), and will expeditiously furnish to the Underwriters and dealers a reasonable number of copies thereof; provided that, if any such event necessitating a supplement or amendment to the Prospectus occurs at any time after nine months after the time of issuance of the Prospectus, such supplement or amendment shall be prepared at the Underwriters’ expense. In the event that the Issuers and the Representatives agree that the Prospectus should be amended or supplemented, the Issuers, if requested by the Representatives, will promptly issue a press release announcing or disclosing the matters to be covered by the proposed amendment or supplement unless the Issuers shall have determined, based on the advice of counsel, that the issuance of such press release would not be required by law.

(g) Blue Sky Laws. The Issuers will cooperate with the Representatives and with counsel for the Underwriters in connection with the registration or qualification of the Notes for offering and sale by the Underwriters and by dealers under the securities or Blue Sky laws of such jurisdictions as the Underwriters may reasonably designate and will file such consents to service of process or other documents reasonably necessary or appropriate in order to effect such registration or qualification; provided that in no event shall any Plains Entity 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 Notes, in any jurisdiction where it is not now so subject. The Issuers will promptly notify the Representatives of the receipt by the Issuers of any notification with respect to the suspension of the qualification of the Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.

(h) Reports to Security Holders. In accordance with Section 11(a) of the Securities Act and Rule 158 of the Rules and Regulations, the Issuers will make generally available to their 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 such Rule 158) of the Registration Statement as soon as practicable after the end of such period.

(i) Copies of Reports. Unless otherwise available on EDGAR, during the period of two years hereafter, the Issuers will furnish or make available to the Underwriters (i) as soon as publicly available, a copy of each report of the Issuers mailed to unitholders or filed with the Commission or the principal national securities exchange or automated quotation system upon which the Notes may be listed, and (ii) from time to time such other information concerning the Issuers as the Underwriters may reasonably request.

(j) Termination Expenses. If this Agreement shall terminate or shall be terminated after execution pursuant to any provisions hereof (otherwise than pursuant to Section 9 hereof or Section 10 hereof (except pursuant to the first clause of Section 10(i))) or if this Agreement shall be terminated by the Underwriters because of any failure or refusal on the part of either of the Issuers to comply with the terms or fulfill any of the conditions of this Agreement, the Issuers, jointly and severally, agree to reimburse the Underwriters for all reasonable out-of-pocket expenses (including reasonable fees and expenses of counsel for the Underwriters) incurred by the Underwriters in connection herewith.

(k) Application of Proceeds. The Issuers will apply the net proceeds from the sale of the Notes in accordance with the description set forth under the caption “Use of Proceeds” in the Pricing Disclosure Package and the Prospectus.

(l) Filing of Prospectus. The Issuers will timely file the Prospectus, and any amendment or supplement thereto, pursuant to Rule 424(b) of the Rules and Regulations and will advise the Underwriters of the time and manner of such filing.

(m) Stabilization. Except as stated in this Agreement and the Prospectus, neither of the Issuers has taken, or will 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 any security of the Issuers to facilitate the sale or resale of the Notes.

(n) Investment Company. The Issuers will take such steps as shall be necessary to ensure that none of the Plains Entities or the GP Entities shall become an “investment company” within the meaning of such term under the Investment Company Act and the rules and regulations of the Commission thereunder.

(o) Exchange Act Reports. The Issuers, during the period when the Prospectus is required to be delivered under the Securities Act, will file all documents required to be filed with the Commission pursuant to the Exchange Act within the time periods required by the Exchange Act.

(p) Free Writing Prospectuses. The Issuers have complied and will comply with the requirements of Rule 433 of the Rules and Regulations applicable to any Issuer Free Writing Prospectus, including appropriate legending and timely filing with the Commission or retention where required. The Issuers represent that they have satisfied and agree that they will satisfy the conditions under Rule 433 of the Rules and Regulations to avoid a requirement to file with the Commission any electronic road show. The Issuers agree that if at any time following issuance of an Issuer Free Writing Prospectus any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the most recent Preliminary Prospectus or the Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, the Issuers will give prompt notice thereof to the Representatives and, if requested by the Representatives, will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document that will correct such conflict, statement or omission; provided, however, that this representation and warranty shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to the Issuers by an Underwriter through the Representatives expressly for use therein, which information is specified in Section 12.

(q) Clear Market. During the period from the date hereof through and including the business day following the Delivery Date, the Issuers will not, without the prior written consent of the Representatives, offer, sell, contract to sell or otherwise dispose of any debt securities issued or guaranteed by the Issuers and having a tenor of more than one year.

6. Indemnification and Contribution.

(a) Each of the Issuers, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of each Underwriter, each affiliate of any Underwriter who has participated in the distribution of the Notes as underwriters, each broker-dealer affiliate of any Underwriter and each other affiliate of any Underwriter within the meaning of Rule 405 of the Rules and Regulations, and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act from and against any and all losses, claims, damages, liabilities and expenses, joint or several (including reasonable costs of investigation), to which they or any of them became subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages, liabilities or expenses arise out of, or are based upon, (i) any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any “road show” (as defined in Rule 433 of the Rules and Regulations) not constituting an Issuer Free Writing Prospectus (a “Non-Prospectus Road Show”) or (ii) the omission or alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, any material fact required to be stated therein or necessary to make the statements therein (in the case of any Preliminary Prospectus or the Prospectus, in the light of the circumstances under which any such statements were made) not misleading, and shall reimburse each Underwriter and each such director, officer, employee or controlling person promptly upon demand for any legal or other expenses reasonably incurred by that Underwriter, director, officer, employee or controlling person in connection with investigating or defending or preparing to defend against any such loss, claim,

damage, liability or action as such expenses are incurred; provided, however, that the Issuers shall not be liable in any such case to the extent that any such loss, claim, damage, liability or action arises out of, or is based upon, any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any such amendment or supplement thereto or in any Non-Prospectus Road Show, in reliance upon and in conformity with written information concerning such Underwriter furnished to the Issuers through the Representatives by or on behalf of any Underwriter specifically for inclusion therein, which information consists solely of the information specified in Section 12. The foregoing indemnity agreement is in addition to any liability that the Issuers may otherwise have to any Underwriter or to any director, officer, employee or controlling person of that Underwriter.

(b) If any action, suit or proceeding shall be brought against any Underwriter, any director, officer, employee or agent of any Underwriter or any person controlling any Underwriter in respect of which indemnity may be sought against an Issuer, such Underwriter or such director, officer, employee, agent or controlling person shall promptly notify the Partnership in writing, and the Issuers 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 Underwriter 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 Underwriter or such director, officer, employee, agent or controlling person unless (i) the Issuers have agreed in writing to pay such fees and expenses, (ii) the Issuers have 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 Issuers (in which case the Issuers 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 Issuers shall pay the reasonable fees and expenses of such counsel as such fees and expenses are incurred (it being understood, however, that the Issuers 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 Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Issuers, GP LLC’s directors and the officers who sign the Registration Statement, and any person who controls either of the Issuers within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act, to the same extent as the foregoing indemnity from the Issuers to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, which information is limited to the information set forth in Section 12. If any action, suit or

proceeding shall be brought against an Issuer, any of such directors and officers or any such controlling person based on the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto or in any Non-Prospectus Road Show, and in respect of which indemnity may be sought against any Underwriter pursuant to this paragraph (c), such Underwriter shall have the rights and duties given to the Issuers by paragraph (b) above (except that if the Issuers shall have assumed the defense thereof such Underwriter 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 Underwriter’s expense), and the Issuers, any of such directors and officers and any such controlling person shall have the rights and duties given to the Underwriters by paragraph (b) above. The foregoing indemnity agreement shall be in addition to any liability that the Underwriters may otherwise have.

(d) If the indemnification provided for in this Section 6 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 Issuers on the one hand and the Underwriters on the other hand from the offering of the Notes, 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 Issuers on the one hand and the Underwriters 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 Issuers on the one hand and the Underwriters on the other shall be deemed to be in the same proportion as the total net proceeds from the offering (before deducting expenses) received by the Issuers bear to the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Issuers on the one hand and the Underwriters 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 Issuers or any affiliate of the Issuers on the one hand, or by the Underwriters 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 Issuers and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 6 were determined by a pro rata allocation (even if the Underwriters were treated as one entity for such purpose) 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 6, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price of the Notes underwritten by it and distributed to the public exceeds the amount of any damages that such

Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligations to contribute as provided in this Section 6 are several and not joint.

(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 6 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 6 and the covenants, representations and warranties of the Issuers 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 Underwriter or any person controlling any Underwriter or the Issuers, GP LLC or any of their respective directors or officers or any person controlling the Issuers, (ii) acceptance of any Notes and payment therefor in accordance with the terms of this Agreement, and (iii) any termination of this Agreement. A successor to any Underwriter or any person controlling any Underwriter, or to the Issuers, GP LLC or any of their respective directors or officers or any person controlling an Issuer shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 6.

If any one or more of the Underwriters shall fail or refuse to purchase Notes that it or they are obligated to purchase hereunder on the Delivery Date, and the aggregate principal amount of Notes that such defaulting Underwriter or Underwriters are obligated but fail or refuse to purchase is not more than one-tenth of the aggregate principal amount of the Notes that the Underwriters are obligated to purchase on the Delivery Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion that the principal amount of Notes set forth opposite its name in Schedule I hereto bears to the aggregate principal amount of Notes set forth opposite the names of all non-defaulting Underwriters or in such other proportion as the Representatives may specify in accordance with the Agreement Among Underwriters of Barclays Capital Inc. to purchase the Notes that such defaulting Underwriter or Underwriters are obligated, but fail or refuse, to purchase. If any one or more of the Underwriters shall fail or refuse to purchase Notes that it or they are obligated to purchase on the Delivery Date and the aggregate principal amount of Notes with respect to which such default occurs is more than one-tenth of the aggregate principal amount of Notes that the Underwriters are obligated to purchase on the Delivery Date and arrangements satisfactory to the Representatives and the Issuers for the purchase of such Notes by one or more non-defaulting

Underwriters or other party or parties approved by the Representatives and the Issuers are not made within 36 hours after such default, this Agreement will terminate without liability on the part of any party hereto (other than any defaulting Underwriter). In any such case that does not result in termination of this Agreement, either the Representatives or the Issuers shall have the right to postpone the Delivery Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement and the Prospectus or any other documents or arrangements may be effected. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any such default of any such Underwriter under this Agreement. The term “Underwriter” as used in this Agreement includes, for all purposes of this Agreement, any party not listed in Schedule I hereto who, with the Representatives’ approval and the approval of the Issuers, purchases Notes that a defaulting Underwriter is obligated, but fails or refuses, to purchase.

Any notice under this Section 9 may be given by telegram, telecopy or telephone but shall be subsequently confirmed by letter.

10. Termination of Agreement. This Agreement shall be subject to termination in the Representatives’ absolute discretion, without liability on the part of any Underwriter to any Issuer, by notice to the Issuers prior to delivery of and payment for the Notes, if at any time prior to such time (i) trading in the Partnership’s Common Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the New York Stock Exchange, 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 or Texas state authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States or with respect to Euroclear S.A./N.V. and Clearstream Banking, société anonyme, shall have occurred; or (iii) there shall have occurred any outbreak or escalation of hostilities or acts of terrorism, declaration by the United States of a national emergency or war or other calamity or crisis or any change in financial, political or economic conditions in the United States or elsewhere, the effect of which on financial markets is such as to make it, in the sole judgment of the Underwriters, impractical or inadvisable to proceed with the offering or delivery of the Notes as contemplated by the Prospectus (exclusive of any amendment or supplement thereto). Notice of such termination may be given to the Issuers by telegram, telecopy or telephone and shall be subsequently confirmed by letter.

11. Notice; Successors.

The Issuers hereby waive and release, to the fullest extent permitted by law, any claims that the Issuers may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Issuers by such Underwriters’ investment banking divisions. The Issuers acknowledge that each of the Underwriters is a full service securities firm and as such from time to time, subject to applicable securities laws, may effect transactions for its own account or the account of its customers and hold long or short positions in debt or equity securities of the companies that may be the subject of the transactions contemplated by this Agreement.

The Issuers hereby waive any claims that they may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.

Delivery of the notes is expected to be made against payment therefor on or about December 9, 2014, which is the fifth business day following the date of pricing of the notes (such settlement being referred to as “T+5”). Under Rule 15c6-1 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), trades in the secondary market generally are required to settle in three business days unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes on the date of pricing of the notes or the next succeeding business day will be required, by virtue of the fact that the notes initially will settle in T+5, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement and should consult their own advisers.

The issuers have filed a registration statement (including a base prospectus) and a prospectus supplement with the U.S. Securities and Exchange Commission (the “SEC”) for the offering to which this communication relates. Before you invest, you should read the prospectus supplement for this offering, the issuers’ prospectus in that registration statement and any other documents the issuers have filed with the SEC for more complete information about the issuers and this offering. You may get these documents for free by visiting EDGAR on the SEC web site at www.sec.gov. Alternatively, the issuers, any underwriter or any dealer participating in the offering will arrange to send you the prospectus supplement and prospectus if you request it by calling Barclays Capital Inc. at 1-888-603-5847, SunTrust Robinson Humphrey, Inc. at 1-800-685-4786 or Wells Fargo Securities, LLC at 1-800-645-3751.

LOGO

December 4, 2014

Plains All American Pipeline, L.P.

333 Clay Street, Suite 1600

Houston, Texas 77002

Ladies and Gentlemen:

We have acted as counsel to Plains All American Pipeline, L.P., a Delaware limited partnership (the “Partnership”), with respect to certain legal matters in connection with the registration by the Partnership and PAA Finance Corp., a Delaware corporation and wholly owned subsidiary of the Partnership (“PAA Finance,” and together with the Partnership, the “Issuers”) under the Securities Act of 1933, as amended (the “Securities Act”), of the offer and sale by the Issuers of $500,000,000 aggregate principal amount of 2.60% Senior Notes due 2019 and $650,000,000 aggregate principal amount of 4.90% Senior Notes due 2045 (the “Notes”), to be issued and sold pursuant to the Underwriting Agreement dated December 2, 2014, by and among the Issuers and the Underwriters named therein (the “Underwriting Agreement”).

The Notes are being offered and sold pursuant to a prospectus supplement dated December 2, 2014 (the “Prospectus Supplement”) filed with the Securities and Exchange Commission (the “Commission”) pursuant to Rule 424(b)(5) on December 3, 2014, to the prospectus dated September 27, 2012, (such prospectus, as amended and supplemented by the Prospectus Supplement, the “Prospectus”), included in and forming part of the Registration Statement on Form S-3 (Registration No. 333-184137) (the “Registration Statement”). Capitalized terms used but not defined herein shall have the meanings given such terms in the Underwriting Agreement.

The Notes are to be issued as securities pursuant to that certain Indenture, dated as of September 25, 2002 (the “Base Indenture”), by and among the Issuers, and U.S. Bank National Association, as successor to Wachovia Bank, National Association, as trustee (the “Trustee”), as amended and supplemented by the Twenty-Seventh Supplemental Indenture and the Twenty-Eighth Supplemental Indenture thereto, to be dated as of December 9, 2014 (the “Supplemental Indentures”), by and among the Issuers and the Trustee (the Base Indenture, as so amended and supplemented by the Supplemental Indentures, the “Indenture”).

In rendering the opinions set forth below, we have examined and relied upon (i) the Registration Statement, the Prospectus Supplement and the Prospectus; (ii) the Fourth Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of May 17, 2012, as amended; (iii) the organizational certificates and the limited partnership or limited liability company agreements (as the case may be) of PAA GP LLC, a Delaware limited liability company (“General Partner”), which is the general partner of the Partnership, of Plains AAP, L.P., a Delaware limited partnership (“Plains AAP”), which owns a 100% membership interest in the General Partner, and of Plains All American GP LLC, a Delaware limited liability company, which is the general partner of Plains AAP; (iv) the bylaws and certificate of incorporation of PAA Finance; (v) the Underwriting Agreement, a copy of which is being filed

with the Securities and Exchange Commission, together with this Exhibit 5.1, as an exhibit to the Partnership’s Current Report on Form 8-K prior to the closing of the sale of the Notes; (vi) the Base Indenture and the Supplemental Indentures and (vii) such other certificates, statutes and other instruments and documents as we consider appropriate for purposes of the opinions hereafter expressed. In addition, we reviewed such questions of law as we considered appropriate.

Based upon and subject to the foregoing and the assumptions, limitations and qualifications set forth herein, we are of the opinion that when (a) the Supplemental Indentures have been duly executed and delivered by the parties thereto and (b) the Notes have been duly executed, authenticated, issued and delivered in accordance with the provisions of the Indenture and duly purchased and paid for in accordance with the terms of the Underwriting Agreement, the Notes will constitute valid and legally binding obligations of the Issuers, enforceable against the Issuers in accordance with their terms.

The opinions expressed herein are qualified in the following respects:

A. As to any facts material to the opinion contained herein, we have made no independent investigation of such facts and have relied, to the extent that we deem such reliance proper, upon certificates of public officials and officers or other representatives of the Partnership.

B. We have assumed that (i) all information contained in all documents submitted to us for review is accurate and complete, (ii) each such document submitted to us as an original is authentic and each such document submitted to us as a copy conforms to an authentic original of such document, (iii) all signatures on each such document examined by us are genuine, (iv) each certificate from governmental officials reviewed by us is accurate, complete and authentic, and all official public records are accurate and complete and (v) each natural person signing any document reviewed by us had the legal capacity to do so and each person signing in a representative capacity any document reviewed by us had authority to sign in such capacity.

C. This opinion is limited in all respects to the laws of the State of New York. We do not express any opinions as to the laws of any other jurisdiction.

D. The opinion is qualified to the extent that the enforceability of any document, instrument or security may be limited by or subject to bankruptcy, insolvency, fraudulent transfer or conveyance, reorganization, moratorium or other similar laws relating to or affecting creditors’ rights generally, and general equitable or public policy principles.

E. We express no opinions concerning (i) the validity or enforceability of any provisions contained in the Indenture that purport to waive or not give effect to rights to notices, defenses, subrogation or other rights or benefits that cannot be effectively waived under applicable law or (ii) the enforceability of indemnification provisions to the extent they purport to relate to liabilities resulting from or based upon negligence or any violation of federal or state securities or blue sky laws.

We hereby consent to the filing of this opinion of counsel as Exhibit 5.1 to the Current Report on Form 8-K of the Partnership dated on or about the date hereof, to the incorporation by reference of this opinion of counsel into the Registration Statement and to the reference to our Firm under the heading “Legal Matters” in the Prospectus Supplement and the Prospectus. In giving such consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act or the rules and regulations of the Commission issued thereunder.

Very truly yours,
