(b) Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each Enterprise Party, the directors of the General Partner and EPOGP, the respective officers of the General Partner and EPOGP who signed the Registration Statement, and each person who controls the Enterprise Parties within the meaning of either the Securities Act or the Exchange Act to the same extent as the foregoing indemnity from the Partnership to the Underwriters, but only

with reference to written information relating to the Underwriters furnished to the Partnership and EPO by the Underwriters through the Representatives specifically for inclusion in the documents referred to in the foregoing indemnity. This indemnity agreement will be in addition to any liability which the Underwriters may otherwise have. The Enterprise Parties acknowledge that the following statements set forth in the most recent Preliminary Prospectus and the Prospectus: (A) the names of the Underwriters, (B) the last paragraph of the cover page regarding delivery of the Securities and (C) under the heading “Underwriting,” the third and seventh paragraphs constitute the only information furnished in writing by or on behalf of the Underwriters for inclusion in any Preliminary Prospectus, the Registration Statement, the Prospectus, any Issuer Free Writing Prospectuses or in any amendment or supplement thereto.

(c) Promptly after receipt by an indemnified party under this Section 8 of notice of any claim or the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section 8, notify the indemnifying party in writing of the claim or the commencement thereof; but the failure so to notify the indemnifying party (i) will not relieve it from liability under paragraph (a) or (b) above unless and to the extent it did not otherwise learn of such action and such failure results in the forfeiture by the indemnifying party of substantive rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraph (a) or (b) above. The indemnifying party shall be entitled to appoint counsel of the indemnifying party’s choice at the indemnifying party’s expense to represent the indemnified party in any action for which indemnification is sought (in which case the indemnifying party shall not thereafter be responsible for the reasonable fees, costs and expenses of any separate counsel retained by the indemnified party or parties except as set forth below); provided, however, that such counsel shall be reasonably satisfactory to the indemnified party. Notwithstanding the indemnifying party’s election to appoint counsel to represent the indemnified party in an action, the indemnified party shall have the right to employ separate counsel (including local counsel), and the indemnifying party shall bear the reasonable fees, costs and expenses of such separate counsel if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with a conflict of interest, (ii) the actual or potential defendants in, or targets of, any such action include both the indemnified party and the indemnifying party and the indemnified party shall have reasonably concluded that there may be legal defenses available to it and/or other indemnified parties which are different from or additional to those available to the indemnifying party, (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after notice of the institution of such action or (iv) the indemnifying party shall authorize the indemnified party to employ separate counsel at the expense of the indemnifying party. An indemnifying party will not, without the prior written consent of the indemnified parties, 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 contain any statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) In the event that the indemnity provided in this Section 8 is unavailable to or insufficient to hold harmless an indemnified party for any reason, the Enterprise Parties and the Underwriters agree to contribute to the aggregate losses, claims, damages and liabilities (including legal or other expenses reasonably incurred in connection with investigating or defending same) (collectively, the “Losses”) to which the Enterprise Parties and the Underwriters may be subject in such proportion as is appropriate to reflect the relative benefits received by the Enterprise Parties on the one hand and by the Underwriters on the other from the offering of the Securities; provided, however, that in no case shall (i) any Underwriter be responsible for any amount in excess of the amount by which the total price of the Notes underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages which such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. If the allocation provided by the immediately preceding sentence is unavailable for any reason, the Enterprise Parties and the Underwriters shall contribute in such proportion as is appropriate to reflect not only such relative benefits but also the relative fault of the Enterprise Parties on the one hand and of the Underwriters on the other in connection with the statements or omissions which resulted in such Losses as well as any other relevant equitable considerations. Benefits received by the Enterprise Parties shall be deemed to be equal to the total net proceeds from the Offering (before deducting expenses) received by it, and benefits received by the Underwriters shall be deemed to be equal to the total underwriting discounts and commissions, in each case as set forth on the cover page of the Prospectus. Relative fault shall be determined by reference to, among other things, whether any untrue or any alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information provided by the Enterprise Parties on the one hand or the Underwriters on the other, the intent of the parties and their relative knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. The Enterprise Parties and each of the Underwriters agree that it would not be just and equitable if contribution were determined by pro rata allocation or any other method of allocation which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this paragraph (d), no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. For purposes of this Section 8, each person who controls any Underwriter within the meaning of either the Securities Act or the Exchange Act, each affiliate of any underwriter who has, or who is alleged to have, participated in the distribution of the Securities as an underwriter, and each director, officer, employee and agent of any Underwriter shall have the same rights to contribution as the Underwriters, and each person who controls the Enterprise Parties within the meaning of either the Securities Act or the Exchange Act, each officer of the General Partner and EPOGP who shall have signed the Registration Statement and each director of the General Partner and EPOGP shall have the same rights to contribution as the Enterprise Parties, subject in each case to the applicable terms and conditions of this paragraph (d).

9. No Fiduciary Duty. Each Enterprise Party hereby acknowledges that each Underwriter is acting solely as an underwriter in connection with the purchase and sale of the Securities. Each Enterprise Party further acknowledges that each Underwriter is acting pursuant to a contractual relationship created solely by this Agreement entered into on an arm’s-length basis and in no event do the parties intend that each Underwriter acts or be responsible as a fiduciary to any of the Partnership Entities, their management, unitholders, creditors or any other person in connection with any activity that each Underwriter may undertake or have undertaken in

furtherance of the purchase and sale of the Securities, either before or after the date hereof. Each Underwriter hereby expressly disclaims any fiduciary or similar obligations to any of the Partnership Entities, either in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions, and the Enterprise Parties hereby confirm their understanding and agreement to that effect. The Enterprise Parties and the Underwriters agree that they are each responsible for making their own independent judgments with respect to any such transactions and that any opinions or views expressed by the Underwriters to any of the Partnership Entities regarding such transactions, including but not limited to any opinions or views with respect to the price or market for the Securities, do not constitute advice or recommendations to any of the Partnership Entities. Each Enterprise Party hereby waives and releases, to the fullest extent permitted by law, any claims that any Enterprise Party may have against each Underwriter with respect to any breach or alleged breach of any fiduciary or similar duty to any of the Partnership Entities in connection with the transactions contemplated by this Agreement or any matters leading up to such transactions.

10. Defaulting Underwriters. If, on the Delivery Date, any Underwriter defaults in the performance of its obligations under this Agreement, the remaining non-defaulting Underwriters shall be obligated to purchase the principal amount of the Notes that the defaulting Underwriter agreed but failed to purchase on the Delivery Date in the respective proportions which the principal amount of the Notes set forth opposite the name of each remaining non-defaulting Underwriter in Schedule I hereto bears to the aggregate principal amount of the Notes set forth opposite the names of all the remaining non-defaulting Underwriters in Schedule I hereto; provided, however, that the remaining non-defaulting Underwriters shall not be obligated to purchase any of the Notes on the Delivery Date if the aggregate principal amount of the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on such date exceeds 10% of the aggregate principal amount of the Notes to be purchased on the Delivery Date, and any remaining non-defaulting Underwriters shall not be obligated to purchase more than 110% of the principal amount of the Notes that it agreed to purchase on the Delivery Date pursuant to the terms of Section 2. If the foregoing maximums are exceeded, the remaining non-defaulting Underwriters, or those other underwriters satisfactory to the Representatives who so agree, shall have the right, but shall not be obligated, to purchase, in such proportion as may be agreed upon among them, the aggregate principal amount of the Notes to be purchased on the Delivery Date. If the remaining Underwriters or other underwriters satisfactory to the Representatives do not elect to purchase the Notes that the defaulting Underwriter or Underwriters agreed but failed to purchase on the Delivery Date, this Agreement shall terminate without liability on the part of any non-defaulting Underwriters or the Partnership, except that the Partnership will continue to be liable for the payment of expenses to the extent set forth in Sections 6 and 12. As used in this Agreement, the term “Underwriter” includes, for all purposes of this Agreement unless the context requires otherwise, any party not listed in Schedule I hereto that, pursuant to this Section 10, purchases Notes that a defaulting Underwriter agreed but failed to purchase.

Nothing contained herein shall relieve a defaulting Underwriter of any liability it may have to the Partnership for damages caused by its default. If other Underwriters are obligated or agree to purchase the Notes of a defaulting or withdrawing Underwriter, either the Representatives or the Partnership may postpone the Delivery Date for up to seven full business days in order to effect any changes that in the opinion of counsel for the Partnership or counsel for the Underwriters may be necessary in the Registration Statement, the Prospectus or in any other document or arrangement.

11. Termination. The obligations of the Underwriters hereunder may be terminated by the Representatives by notice given to and received by the Partnership prior to delivery of and payment for the Notes if, prior to that time, any of the events described in Sections 7(n) or 7(o) shall have occurred or if the Underwriters shall decline to purchase the Notes for any reason permitted under this Agreement.

12. Reimbursement of Underwriters’ Expenses. If the sale of the Securities provided for herein is not consummated because any condition to the obligations of the Underwriters set forth in Section 7 hereof is not satisfied or because of any refusal, inability or failure on the part of any Enterprise Party to perform any agreement herein or comply with any provision hereof other than by reason of a default by the Underwriters, the Partnership and EPO will reimburse the Underwriters, severally through the Representatives, on demand for all reasonable out-of-pocket expenses (including reasonable fees and disbursements of counsel) that shall have been incurred by the Underwriters in connection with the proposed purchase and sale of the Securities. If this Agreement is terminated pursuant to Section 10 hereof by reason of the default of one or more of the Underwriters, the Partnership and EPO shall not be obligated to reimburse any defaulting Underwriter on account of such Underwriter’s expenses.

13. Issuer Information. Each Underwriter severally agrees that such Underwriter, without the prior written consent of the Partnership, has not used or referred to publicly and shall not use or refer to publicly any “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, other than a free writing prospectus containing the information contained in the final term sheet prepared and filed pursuant to Section 5(b) of this Agreement; provided that the prior written consent of the parties hereto shall be deemed to have been given in respect of the Free Writing Prospectuses included in Schedule II hereto and any electronic road show. Any such free writing prospectus consented to by the Representatives or the Partnership is hereinafter referred to as a “Permitted Free Writing Prospectus.” The Partnership agrees that (x) it has treated and will treat, as the case may be, each Permitted Free Writing Prospectus as an Issuer Free Writing Prospectus and (y) it has complied and will comply, as the case may be, with the requirements of Rules 164 and 433 applicable to any Permitted Free Writing Prospectus, including in respect of timely filing with the Commission, legending and record keeping.

14. Notices. All statements, requests, notices and agreements hereunder shall be in writing, and:

Nothing in this Agreement is intended or shall be construed to give any person, other than the persons referred to in this Section 16, any legal or equitable right, remedy or claim under or in respect of this Agreement or any provision contained herein.

16. Survival. The respective indemnities, representations, warranties and agreements of the Enterprise Parties and the Underwriters contained in this Agreement or made by or on behalf on them, respectively, pursuant to this Agreement or any certificate delivered pursuant hereto, shall survive the delivery of and payment for the Securities and shall remain in full force and effect, regardless of any termination or cancellation of this Agreement or any investigation made by or on behalf of any of them or any person controlling any of them. The Underwriters acknowledge and agree that the obligations of the Enterprise Parties hereunder are non-recourse to the General Partner.

17. Definition of the Terms “Business Day” and “Subsidiary”. For purposes of this Agreement, (a) “business day” means any day on which the New York Stock Exchange, Inc. is open for trading and (b) “affiliate” and “subsidiary” have their respective meanings set forth in Rule 405 of the Rules and Regulations.

18. Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

19. Jurisdiction; Venue. The parties hereby consent to (i) nonexclusive jurisdiction in the courts of the State of New York located in the City and County of New York or in the United States District Court for the Southern District of New York, (ii) nonexclusive personal service with respect thereto, and (iii) personal jurisdiction, service and venue in any court in which any claim arising out of or in any way relating to this Agreement is brought by any third party against the Underwriters or any indemnified party.

22. Headings. The headings herein are inserted for convenience of reference only and are not intended to be part of, or to affect the meaning or interpretation of, this Agreement.

23. Recognition of the U.S. Special Resolution Regime.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

FORM OF DEPUTY GENERAL COUNSEL’S OPINION

1. Each of the Enterprise Parties and each of the Partnership Entities that is a “significant subsidiary” of EPO as such term is defined in Rule 1-02(w) of Regulation S-X under the Securities Act (which Partnership Entities have been identified as such on Schedule III to the Underwriting Agreement)(the “Significant Partnership Subsidiaries”) has been duly formed or incorporated, as the case may be, and (other than the Enterprise Parties) is validly existing and in good standing under the laws of its jurisdiction of formation with all necessary corporate, limited liability company or limited partnership, as the case may be, power and authority to own or lease its properties and conduct its business, in each case in all material respects as described in each of the Pricing Disclosure Package and the Prospectus. Each of the Significant Partnership Subsidiaries is duly registered or qualified as a foreign corporation, limited partnership or limited liability company, as the case may be, for the transaction of business under the laws of each jurisdiction in which its ownership or lease of property or the conduct of its businesses requires such qualification or registration, except where the failure to so qualify or register would not, individually or in the aggregate, have a material adverse effect on the financial condition, business or results of operations of the Partnership Entities, taken as a whole.

2. All of the outstanding shares of capital stock, partnership interests or membership interests, as the case may be, of each of the Significant Partnership Subsidiaries have been duly and validly authorized and issued in accordance with the applicable constituent documents and are fully paid (to the extent required under the applicable constituent documents) and non-assessable (except as such non-assessability may be affected by Sections 17-303, 17-607 and 17-804 of the Delaware LP Act, in the case of partnership interests in a Delaware limited partnership; Sections 18-607 and 18-604 of the Delaware LLC Act, in the case of membership interests in a Delaware limited liability company; Section 101.206 of the Texas Act, in the case of membership interests in a Texas limited liability company; and except as otherwise disclosed in each of the Pricing Disclosure Package and the Prospectus).

3. To such counsel’s knowledge, neither the filing of the Registration Statement nor the offering or sale of the Securities as contemplated by the Underwriting Agreement gave or gives rise to any rights for or relating to the registration of any securities of the Partnership, EPO or any of their subsidiaries, other than as have been waived. To such counsel’s knowledge, except for options granted pursuant to employee benefits plans, qualified unit option plans or other employee compensation plans, rights to purchase Common Units under the Partnership’s distribution reinvestment plan or rights to purchase securities pursuant to the governing documents of the Enterprise Parties and each of the Significant Partnership Subsidiaries, there are no outstanding options or warrants to purchase any partnership interests, membership interests or capital stock in the Enterprise Parties or any Significant Partnership Subsidiary.

6. To the knowledge of such counsel, (a) there is no legal or governmental proceeding pending or threatened against the Partnership Entities, or to which any of the Partnership Entities is a party, or to which any of their respective properties is subject, that is required to be disclosed in the Pricing Disclosure Package or the Prospectus and is not so disclosed and (b) there are no agreements, contracts or other documents to which any of the Partnership Entities is a party that are required to be described in the Pricing Disclosure Package or the Prospectus or to be filed as exhibits to the Registration Statement that are not described or filed as required by the Securities Act or the Rules and Regulations or the Exchange Act or the rules and regulations thereunder.
