          (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 a Plains Party, such Underwriter or such director, officer, employee, agent or controlling person shall promptly notify the Partnership in writing, and the Partnership, the General Partner, Plains AAP and GP LLC 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 Partnership, the General Partner, Plains AAP and/or GP LLC has agreed in writing to pay such fees and expenses, (ii) the Partnership, the General Partner, Plains AAP and GP LLC 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 which are different from, additional to or in conflict with those available to the Partnership, the General Partner, Plains AAP and/or GP LLC (in which case the Partnership, the General Partner, Plains AAP and GP LLC 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, the General Partner, Plains AAP and/or GP LLC shall pay the reasonable fees and expenses of such counsel as such fees and expenses are incurred (it being understood, however, that the Partnership, the General Partner, Plains AAP and GP LLC 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). None of the Plains Parties shall be liable for any settlement of any such action, suit or proceeding effected without its written consent, but if settled with such written consent, or if there be a final judgment for the plaintiff in any such action, suit or proceeding, the Plains Parties agree, jointly and severally, to indemnify and hold harmless any Underwriter, to the extent provided in the preceding paragraph, and any such controlling person from and against any loss, claim, damage, liability or expense by reason of such settlement or judgment.
          (c) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Plains Parties, their respective directors and the officers who sign the Registration Statement, and any person who controls the Plains Parties 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 Plains Parties to each Underwriter, but only with respect to information furnished in writing by or on behalf of such Underwriter through you expressly for use in the Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, which information is limited to the information set forth in Section 12. If any action, suit or proceeding shall be brought against a Plains Party, any of such directors and officers or any such controlling person based on the

- 22 -


 

Registration Statement, any Preliminary Prospectus, the Prospectus, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, 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 Plains Parties by paragraph (b) above (except that if the Partnership, the General Partner, Plains AAP or GP LLC 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 Plains Parties, 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 Plains Parties on the one hand and the Underwriters 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 Plains Parties 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 Plains Parties 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 Partnership 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 Plains Parties 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 Plains Parties or any other affiliate of the Plains Parties 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 Plains Parties 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 Units 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

- 23 -


 

(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 Plains Parties 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, the Plains Parties or any of their respective directors or officers or any person controlling the Plains Parties, (ii) acceptance of any Units 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 Plains Parties or any of their respective directors or officers or any person controlling a Plains Party shall be entitled to the benefits of the indemnity, contribution and reimbursement agreements contained in this Section 6.
          7. Conditions of Underwriters’ Obligations. The several obligations of the Underwriters to purchase the Firm Units and the Option Units, as the case may be, hereunder are subject to the following conditions:
          (a) All filings required by Rule 424 and Rule 430A of the Rules and Regulations shall have been made.

          (g) You shall have received on each applicable Delivery Date an opinion of Baker Botts L.L.P., counsel for the Underwriters, dated the applicable Delivery Date and addressed to you, with respect to the issuance and sale of the Units, the Registration Statement, the Pricing Disclosure Package and the Prospectus (together with any supplement or amendment thereto) and other related matters the Underwriters may reasonably require.

- 36 -

          All such opinions, certificates, letters and other documents referred to in this Section 7 will be in compliance with the provisions hereof only if they are reasonably satisfactory in form and substance to you and your counsel. The Partnership shall furnish to the Underwriters conformed copies of such opinions, certificates, letters and other documents in such number as they shall reasonably request.
          The several obligations of the Underwriters to purchase Option Units hereunder are subject to the satisfaction on and as of any Option Units Delivery Date of the conditions set forth in this Section 7, except that, if any Option Units Delivery Date is other than the Initial Delivery Date, (i) the certificates, opinions and letters referred to in paragraphs (c) through (h) and (l) through (n) shall be dated the Option Units Delivery Date in question, (ii) the opinions called for by paragraphs (c), (d), (e), (f) and (g), as applicable, shall be revised to reflect the sale of Option Units and (iii) any references in Section 7 to the Initial Delivery Date shall be deemed to be such Option Units Delivery Date.
          8. Expenses. The Partnership agrees to pay the following costs and expenses and all other costs and expenses incident to the performance by it of its obligations hereunder: (i) the preparation, printing or reproduction, and filing with the Commission of the Registration Statement (including financial statements and exhibits thereto), any Preliminary Prospectus, the Prospectus, and each amendment or supplement to any of them; (ii) the printing (or reproduction) and delivery (including postage, air freight charges and charges for counting and packaging) of such copies of the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, the Prospectus, the Incorporated Documents and all amendments or supplements to any of them as may be reasonably requested for use in connection with the offering and sale of the Units; (iii) the preparation, printing, authentication, issuance and delivery of certificates for the Units, including any stamp taxes in connection with the original issuance and sale of the Units; (iv) the printing (or reproduction) and delivery of this Agreement, the preliminary and supplemental Blue Sky Memoranda, and all other agreements or documents printed (or reproduced) and delivered in connection with the offering of the Units; (v) the registration of the Common Units under the Exchange Act and the listing of the Units on the NYSE; (vi) the registration or qualification of the Units for offer and sale under the securities or Blue Sky laws of the several states as provided in Section 5(f) hereof (including the reasonable fees, expenses and disbursements of counsel for the Underwriters relating to the preparation, printing or reproduction, and delivery of the preliminary and supplemental Blue Sky Memoranda and such registration and qualification); (vii) any filing fees in connection with any filings required to be made with the Financial Industry Regulatory Authority; (viii) the transportation and other expenses incurred by or on behalf of officers and employees of GP LLC or the Partnership in connection with presentations to prospective purchasers of the Units; and (ix) the fees and expenses of the Partnership’s accountants and the fees and expenses of counsel (including local and special counsel) for the Partnership.

- 38 -


 

expenses incurred by the Underwriters on their own behalf in connection with presentations to prospective purchasers of the Units.
          9. Default by an Underwriter. If any one or more of the Underwriters shall fail or refuse to purchase Units that it or they are obligated to purchase hereunder on the Initial Delivery Date, and the aggregate number of Units that such defaulting Underwriter or Underwriters are obligated but fail or refuse to purchase is not more than one-tenth of the aggregate number of the Units that the Underwriters are obligated to purchase on the Initial Delivery Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion that the number of Firm Units set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Units set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in accordance with the Agreement Among Underwriters of Wachovia Capital Markets, LLC to purchase the Units 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 Units that it or they are obligated to purchase on the Initial Delivery Date and the aggregate number of Units with respect to which such default occurs is more than one-tenth of the aggregate number of Units that the Underwriters are obligated to purchase on the Initial Delivery Date and arrangements satisfactory to you and the Partnership for the purchase of such Units by one or more non-defaulting Underwriters or other party or parties approved by you and the Partnership are not made within five business days after such default, this Agreement will terminate without liability on the part of any party hereto (other than the defaulting Underwriter). In any such case that does not result in termination of this Agreement, either you or the Partnership shall have the right to postpone the Initial 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. If any one or more of the Underwriters shall fail or refuse to purchase Option Units that it or they are obligated to purchase hereunder on the Option Units Delivery Date, each non-defaulting Underwriter shall be obligated, severally, in the proportion that the number of Firm Units set forth opposite its name in Schedule I hereto bears to the aggregate number of Firm Units set forth opposite the names of all non-defaulting Underwriters or in such other proportion as you may specify in accordance with the Agreement Among Underwriters of Wachovia Capital Markets, LLC, to purchase the Option Units that such defaulting Underwriter or Underwriters are obligated, but fail or refuse, to purchase. 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 your approval and the approval of the Partnership, purchases Units 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 your absolute discretion, without liability on the part of any Underwriter to any Plains Party, by notice to the Partnership, if prior to the Initial Delivery Date or any Option Units Delivery Date (if different from the Initial Delivery Date and then only as to the Option Units), as the case may be, (i) trading in the Common Units shall have been suspended by the Commission or the NYSE or trading in securities generally on the New York Stock Exchange,

- 39 -


 

the American Stock Exchange 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 shall have occurred, 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 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 Units as contemplated by the Prospectus (exclusive of any supplement thereto). Notice of such termination may be given to the Partnership by telegram, telecopy or telephone and shall be subsequently confirmed by letter.
          11. Notice; Successors. Except as otherwise provided in Sections 5, 9 and 10 hereof, all communications hereunder will be in writing and effective only on receipt, and, if sent to the Underwriters, will be mailed, delivered or telefaxed to Wachovia Capital Markets, LLC, Attention: Legal Division, Equity Capital Markets (fax no.: 212 ###-###-####) and confirmed to it at Wachovia Capital Markets, LLC, 375 Park Avenue, New York, New York 10152, Attention Legal Division, Equity Capital Markets; or, if sent to any of the Plains Parties, will be mailed, delivered or telefaxed to (713)  ###-###-#### and confirmed to it at 333 Clay St., Suite 1600, Houston, Texas 77002, Attention: Tim Moore.

          This Agreement has been and is made solely for the benefit of the several Underwriters, the Plains Parties, their directors and officers, and the other controlling persons referred to in Section 6 hereof and their respective successors and assigns, to the extent provided herein, and no other person shall acquire or have any right under or by virtue of this Agreement. Neither the term “successor” nor the term “successors and assigns” as used in this Agreement shall include a purchaser from any Underwriter of any of the Units in his status as such purchaser.
          13. Research Analyst Independence. The Plains Parties acknowledge that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Partnership and/or the offering that differ from the views of their respective investment banking divisions. The Plains Parties hereby waive and release, to the fullest extent permitted by law, any claims that the Plains Parties 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 Plains Parties by such Underwriters’ investment banking divisions. The Plains Parties 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

- 40 -


 

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.
          14. No Fiduciary Duty. The Plains Parties acknowledge and agree that in connection with this offering, sale of the Units or any other services the Underwriters may be deemed to be providing hereunder, notwithstanding any preexisting relationship, advisory or otherwise, between the parties or any oral representations or assurances previously or subsequently made by the Underwriters: (i) no fiduciary or agency relationship between the Plains Parties and any other person, on the one hand, and the Underwriters, on the other hand, exists; (ii) the Underwriters are not acting as advisors, expert or otherwise, to any of the Plains Parties, including, without limitation, with respect to the determination of the public offering price of the Units, and such relationship between the Plains Parties, on the one hand, and the Underwriters, on the other, is entirely and solely commercial, based on arms-length negotiations; (iii) any duties and obligations that the Underwriters may have to the Plains Parties shall be limited to those duties and obligations specifically stated herein; and (iv) the Underwriters and their respective affiliates may have interests that differ from those of the Plains Parties. The Plains Parties hereby waive any claims that they may have against the Underwriters with respect to any breach of fiduciary duty in connection with this offering.
          15. Applicable Law; Counterparts. This Agreement shall be governed by and construed in accordance with the laws of the State of New York applicable to contracts made and to be performed within the State of New York.
          This Agreement may be signed in various counterparts which together constitute one and the same instrument. If signed in counterparts, this Agreement shall not become effective unless at least one counterpart hereof shall have been executed and delivered on behalf of each party hereto.
