Other Events.

On August 7, 2017, Enterprise Products Partners L.P. (the “Partnership”), Enterprise Products OLPGP, Inc. (“EPOGP”) and Enterprise Products Operating LLC (“EPO”) entered into an underwriting agreement (the “Underwriting Agreement”) with Citigroup Global Markets Inc. and Barclays Capital Inc., as representatives of the several underwriters named on Schedule I thereto (the “Underwriters”), relating to the public offering of $700.0 million principal amount of EPO’s 4.875% Junior Subordinated Notes D due August 16, 2077 (the “Non-Call 5 Notes”) and $1.0 billion principal amount of EPO’s 5.250% Junior Subordinated Notes E due August 16, 2077 (the “Non-Call 10 Notes” and, together with the Non-Call 5 Notes, the “Notes”). The Notes are unconditionally guaranteed on a junior subordinated basis by the Partnership pursuant to a guarantee (the “Guarantee” and, together with the Notes, the “Securities”) included in the Indenture (as defined below). Closing of the issuance and sale of the Securities is scheduled for August 16, 2017 (the “Closing”).

The offering of the Securities has been registered under the Securities Act of 1933, as amended (the “Securities Act”), pursuant to a Registration Statement on Form S-3 (Registration Nos. 333-211317 and 333-211317-01) (the “Registration Statement”), as supplemented by the Prospectus Supplement dated August 7, 2017, relating to the Securities, filed with the United States Securities and Exchange Commission on August 8, 2017, pursuant to Rule 424(b) of the Securities Act (together with the accompanying prospectus dated May 12, 2016, the “Prospectus”).

The Underwriting Agreement provides that the obligations of the Underwriters to purchase the Notes are subject to customary conditions. The Underwriters are obligated to purchase all of the Notes if they purchase any of the Notes. The Partnership, EPO and EPOGP have agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act, or to contribute to payments the Underwriters may be required to make because of any of those liabilities. The Underwriting Agreement also contains other customary representations, warranties and agreements. The summary of the Underwriting Agreement in this report does not purport to be complete and is qualified by reference to such agreement, which is filed as an exhibit hereto and incorporated herein by reference. The Underwriting Agreement contains representations, warranties and other provisions that were made or agreed to, among other things, to provide the parties thereto with specified rights and obligations and to allocate risk among them. Accordingly, the Underwriting Agreement should not be relied upon as constituting a description of the state of affairs of any of the parties thereto or their affiliates at the time it was entered into or otherwise.

The Prospectus provides that EPO expects to use the net proceeds from the Notes offering for (i) the repayment of debt, which may include the temporary repayment of amounts outstanding under its commercial paper notes program, payment of its $800 million principal amount of Senior Notes L due September 2017 at their maturity, and the redemption prior to maturity of up to $700 million aggregate principal amount of its outstanding Junior Subordinated Notes A due August 2066, Junior Subordinated Notes B due January 2068, and/or Junior Subordinated Notes C due June 2067 and (ii) for general company purposes. Affiliates of certain of the Underwriters may hold EPO’s commercial paper notes, Senior Notes L, Junior Subordinated Notes A, Junior Subordinated Notes B, and/or Junior Subordinated Notes C to be repaid or redeemed with proceeds from this offering and, accordingly, may receive a substantial portion of the net proceeds from the offering of Notes. In addition, certain of the Underwriters and their respective affiliates have, from time to time, performed, and may in the future perform, various financial advisory, commercial banking and investment banking services for the Partnership and its affiliates, for which they received or will receive customary fees and expense reimbursement.

The Securities are being issued under the Indenture, dated as of October 4, 2004 (the “Indenture”), among EPO (as successor to Enterprise Products Operating L.P.), as issuer, the Partnership, as guarantor, and Wells Fargo Bank, N.A., as trustee (collectively, as amended and supplemented by the Tenth Supplemental Indenture, dated as of June 30, 2007, providing for EPO as successor issuer, the “Base Indenture”) and the Twenty-Ninth Supplemental Indenture thereto, to be dated as of August 16, 2017 (the “Twenty-Ninth Supplemental Indenture” and, together with the Tenth Supplemental Indenture, the “Supplemental Indentures”). The terms of the Securities, the Base Indenture and the Supplemental Indentures are further described in the Prospectus under the captions “Description of the Notes” and “Description of Debt Securities,” which descriptions are incorporated herein by reference and filed herewith as Exhibit 99.1. Such descriptions do not purport to be complete and are qualified by reference to the Base Indenture, which was filed under a Form 8-K on October 6, 2004, and the Twenty-Ninth Supplemental Indenture, which will be filed under a Form 8-K after the Closing.

On August 7, 2017, the Partnership issued a press release relating to the public offering of the Notes contemplated by the Underwriting Agreement. A copy of the press release is furnished herewith as Exhibit 99.2.

Ladies and Gentlemen:

Enterprise Products Operating LLC, a Texas limited liability company (“EPO”), proposes to issue and sell to the underwriters listed on Schedule I hereto (the “Underwriters”) (i) $700,000,000 aggregate principal amount of EPO’s 4.875% Junior Subordinated Notes D due August 16, 2077 (the “Non-Call 5 Notes”) and (ii) $1,000,000,000 aggregate principal amount of EPO’s 5.250% Junior Subordinated Notes E due August 16, 2077 (the “Non-Call 10 Notes,” and together with the Non-Call 5 Notes, the “Notes”), as set forth on Schedule I hereto, to be fully and unconditionally guaranteed on a junior subordinated basis by Enterprise Products Partners L.P., a Delaware limited partnership (the “Partnership”) (the “Guarantees,” together with the Notes, the “Securities”).

The Securities are to be issued under the Indenture dated as of October 4, 2004 (the “Original Indenture”) among EPO (as successor to Enterprise Products Operating L.P.), as issuer, the Partnership, as parent guarantor, and Wells Fargo Bank, N.A., as trustee (the “Trustee”), as amended and supplemented by (i) the Tenth Supplemental Indenture, dated as of June 30, 2007 (the “Tenth Supplemental Indenture”), providing for EPO as the successor issuer to Enterprise Products Operating L.P., and (ii) the Twenty-Ninth Supplemental Indenture, to be dated as of the Delivery Date (as defined in Section 4 below) (the “Twenty-Ninth Supplemental Indenture”). The Original Indenture, as amended and supplemented by the Tenth Supplemental Indenture and the Twenty-Ninth Supplemental Indenture, is referred to herein as the “Indenture.”

This is to confirm the agreement among the Partnership, Enterprise Products OLPGP, Inc., a Delaware corporation and managing member of EPO (“EPOGP”), and EPO (collectively with the Partnership and EPOGP, the “Enterprise Parties”), and the Underwriters concerning the purchase of the Securities from the Partnership and EPO by the Underwriters.

1. Representations, Warranties and Agreements of the Enterprise Parties. Each of the Enterprise Parties, jointly and severally, represents and warrants to, and agrees with, the Underwriters that:

(a) A registration statement on Form S-3 (File Nos. 333-211317 and 333-211317-01) relating to the Securities (i) has been prepared by the Partnership and EPO pursuant to the requirements of the Securities Act of 1933, as amended (the “Securities Act”), and the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) thereunder; (ii) has been filed with the Commission under the Securities Act; and (iii) is effective under the Securities Act. Copies of such registration statement and any amendment thereto have been made available by the Partnership and EPO to you as the representatives (the “Representatives”) of the Underwriters. As used in this Agreement:

(ii) “Base Prospectus” means the base prospectus included in the Registration Statement at the Applicable Time;

(ii) “Effective Date” means any date as of which any part of such registration statement relating to the Securities became, or is deemed to have become, effective under the Securities Act in accordance with the Rules and Regulations (including for the avoidance of doubt, any effective date with respect to the Underwriters);

(iii) “Issuer Free Writing Prospectus” means each “free writing prospectus” (as defined in Rule 405 of the Rules and Regulations) or “issuer free writing prospectus” (as defined in Rule 433 of the Rules and Regulations) prepared by or on behalf of the Partnership or EPO or used or referred to by the Partnership or EPO in connection with the offering of the Securities;

(iv) “Preliminary Prospectus” means any preliminary prospectus relating to the Securities included in such registration statement or filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, including the Base Prospectus and any preliminary prospectus supplement thereto relating to the Securities;

Any reference to any amendment or supplement to any Preliminary Prospectus or the Prospectus shall be deemed to refer to and include any document filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the date of such Preliminary Prospectus or the Prospectus, as the case may be, and incorporated by reference in such Preliminary Prospectus or the Prospectus, as the case may be; and any reference to any amendment to the Registration Statement shall be deemed to refer to and include the filing of any document under the Exchange Act on or after the initial effective date of the Registration Statement and deemed to be incorporated therein by reference.

(f) Documents Incorporated by Reference.

reliance upon and in conformity with written information furnished to the Partnership and EPO through the Representatives by or on behalf of any Underwriters specifically for inclusion therein, which information is specified in Section 8(b).

(i) Each Issuer Free Writing Prospectus. Each Issuer Free Writing Prospectus conformed or will conform in all material respects to the requirements of the Securities Act and the Rules and Regulations on the date of first use, and the Partnership has complied with any filing requirements applicable to such Issuer Free Writing Prospectus pursuant to the Rules and Regulations. Neither the Partnership nor EPO has made any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus without the prior written consent of the Representatives, except as set forth on Schedule IV hereto. The Partnership and EPO 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 (it being understood that, as of the date hereof, the Partnership and EPO have not retained any Issuer Free Writing Prospectus for the three-year period required thereby). Each Issuer Free Writing Prospectus does not and will not include any information that conflicts with the information contained in the Registration Statement or the Pricing Disclosure Package, including any document incorporated therein and any prospectus supplement deemed to be a part thereof that has not been superseded or modified. The foregoing sentence does not apply to statements in or omissions from any Issuer Free Writing Prospectus based upon and in conformity with written information furnished to the Partnership and EPO by the Underwriters through the Representatives specifically for inclusion therein, which information consists solely of the information specified in Section 8(b).

their agreements contained herein and satisfied all conditions on their part to be performed or satisfied hereunder on or prior to the Delivery Date; (v) no stop order suspending the effectiveness of the Registration Statement has been issued and no proceedings for that purpose have been instituted or, to the best of each such officer’s knowledge, are threatened; (vi) the Commission has not notified the Partnership of any objection to the use of the form of the Registration Statement or any post-effective amendment thereto; (vii) since the date of the most recent financial statements included or incorporated by reference in the Prospectus, there has been no Material Adverse Effect, whether or not arising from transactions in the ordinary course of business, except as set forth in or contemplated in the Pricing Disclosure Package; and (viii) since the Effective Date, no event has occurred that is required under the Rules and Regulations or the Securities Act to be set forth in a supplement or amendment to the Registration Statement, the Prospectus or any Issuer Free Writing Prospectus that has not been so set forth.

(j) If any event shall have occurred on or prior to the Delivery Date that requires the Partnership or EPO under Section 5(e) of this Agreement to prepare an amendment or supplement to the Prospectus, such amendment or supplement shall have been prepared, the Underwriters shall have been given a reasonable opportunity to comment thereon as provided in Section 5(e) hereof, and copies thereof shall have been delivered to the Underwriters reasonably in advance of the Delivery Date.

(m) Subsequent to the execution and delivery of this Agreement there shall not have occurred any of the following: (i) trading in any securities of the Partnership or EPO shall have been suspended by the Commission or the New York Stock Exchange, (ii) trading in securities generally on the New York Stock Exchange or the American Stock Exchange shall have been suspended or materially limited or the settlement of such trading generally shall have been materially disrupted or minimum prices shall have been established on the New York Stock

(n) Subsequent to the execution and delivery of this Agreement, if any debt securities of the Partnership or EPO are rated by any “nationally recognized statistical rating organization,” as that term is defined in Section 3(a)(62) of the Exchange Act, (i) no downgrading shall have occurred in the rating accorded such debt securities (including the Securities) and (ii) no such organization shall have publicly announced that it has under surveillance or review, with possible negative implications, its rating of any securities of any of the Partnership Entities.

8. Indemnification and Contribution.

(a) Each of the Enterprise Parties, jointly and severally, agrees to indemnify and hold harmless each Underwriter, the directors, officers, employees and agents of any Underwriter, affiliates of any Underwriter who have, or who are alleged to have, participated in the distribution of the Securities as underwriters, and each person who controls any Underwriter or any such affiliate within the meaning of either the Securities Act or the Exchange Act from and against any and all losses, claims, damages or liabilities, joint or several, to which that Underwriter, director, officer, employee, agent, affiliate or controlling person may become subject under the Securities Act, the Exchange Act or other Federal or state statutory law or regulation, at common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) 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, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto, or (ii) the omission or the alleged omission to state in the Registration Statement, any Preliminary Prospectus, the Prospectus, the Pricing Disclosure Package, any Issuer Free Writing Prospectus or in any amendment or supplement thereto any material fact required to be stated therein or necessary to make the statements therein not misleading; and agrees to reimburse each such indemnified party, as incurred, for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that the Enterprise Parties 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 therein in reliance upon and in conformity with written information furnished to the Enterprise Parties by the Underwriters through the Representatives specifically for inclusion therein, which information consists solely of the information specified in Section 8(b). This indemnity agreement will be in addition to any liability which the Enterprise Parties may otherwise have.

(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 and the second paragraph under the subheading “Conflicts of Interest” 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(m) or 7(n) 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. Research Analyst Independence. Each of the Enterprise Parties acknowledges 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 each of the Enterprise Parties and/or the offering that differ from the views of their respective investment banking divisions. Each of the Enterprise Parties hereby waives and releases, to the fullest extent permitted by law, any claims that the Enterprise 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 Partnership by such Underwriters’

investment banking divisions. Each of the Enterprise Parties acknowledges 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.

14. 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.

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

Any such statements, requests, notices or agreements shall take effect at the time of receipt thereof.

The Enterprise Parties shall be entitled to rely upon any request, notice, consent or agreement given or made by the Representatives on behalf of the Underwriters.

16. Persons Entitled to Benefit of Agreement. This Agreement shall inure to the benefit of and be binding upon the Underwriters, the Enterprise Parties and their respective successors. This Agreement and the terms and provisions hereof are for the sole benefit of only those persons, except as provided in Section 8 with respect to affiliates, officers, directors, employees, representatives, agents and controlling persons of the Partnership, EPO and the

Underwriters. 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.

17. 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.

18. 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.

Each of the parties (on its behalf and, to the extent permitted by applicable law, on behalf of its limited partners and affiliates) waives all right to trial by jury in any action, proceeding or counterclaim (whether based upon contract, tort or otherwise) in any way arising out of or relating to this Agreement. The parties agree that a final judgment in any such action, proceeding or counterclaim brought in any such court shall be conclusive and binding upon the parties and may be enforced in any other courts to the jurisdiction of which the parties is or may be subject, by suit upon such judgment.

21. Counterparts. This Agreement may be executed in one or more counterparts and, if executed in more than one counterpart, the executed counterparts shall each be deemed to be an original but all such counterparts shall together constitute one and the same instrument.

Amendments to the Preliminary Prospectus Supplement:

The section of the Preliminary Prospectus Supplement entitled “Capitalization” is amended as follows, and all other information (including financial information) presented in the Preliminary Prospectus Supplement is deemed to have changed to the extent affected by the changes set forth below.

In the “As Adjusted” column of the June 30, 2017 capitalization table shown under the section of the Preliminary Prospectus Supplement titled “Capitalization,” the following line items are updated to reflect the assumed application of net proceeds at that date (unaudited): cash and cash equivalents is $28.6 million; Commercial Paper Notes, variable rates is $574.0 million; Senior Notes L, 6.30% fixed-rate, due September 2017 is zero; total principal amount of senior debt obligations is $20,424.0 million; Enterprise Junior Subordinated Notes A, fixed/variable-rate, due August 2066 is $521.1 million; Enterprise Junior Subordinated Notes C, fixed/variable-rate, due June 2067 is $256.4 million; Enterprise Junior Subordinated Notes B, fixed/variable-rate, due January 2068 is $682.7 million; Enterprise Junior Subordinated Notes D, fixed/variable-rate, due August 2077 is $700.0 million; Enterprise Junior Subordinated Notes E, fixed/variable-rate, due August 2077 is $1,000.0 million; total principal amount of senior and junior debt obligations is $23,598.4 million; total other, non-principal amounts is $217.1 million; total debt obligations, including current maturities is $23,381.3 million; and total debt and equity is $46,261.5 million.

Schedule IV - 3

In addition, footnote (1) to the capitalization table shown under the section of the Preliminary Prospectus Supplement titled “Capitalization,” is added to each of the following rows: Enterprise Junior Subordinated Notes A, fixed/variable-rate, due August 2066, Enterprise Junior Subordinated Notes C, fixed/variable-rate, due June 2067 and Enterprise Junior Subordinated Notes B, fixed/variable-rate, due January 2068. Further, such footnote (1) is amended to add the following:

As set forth in “Use of Proceeds,” the Company may issue additional commercial paper notes in order to redeem prior to maturity up to $700 million aggregate principal amount of EPO’s outstanding Junior Subordinated Notes A due August 2066, Junior Subordinated Notes B due January 2068, and/or Junior Subordinated Notes C due June 2067.

EPO expects delivery of the notes will be made against payment therefor on or about August 16, 2017, which is the seventh business day following the date of pricing of the notes (such settlement cycle being referred to as “T+7”). 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 three succeeding business days will be required, by virtue of the fact that the notes initially will settle T+7, to specify an alternate settlement cycle at the time of any such trade to prevent failed settlement. Purchasers of the notes who wish to trade the notes on the date of pricing of the notes or the next three succeeding business days should consult their own advisors.

The Issuer has filed a registration statement (including a prospectus) with the Securities and Exchange Commission (the “SEC”) for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the Issuer has filed with the SEC for more complete information about the Issuer and this offering. You may get these documents for free by visiting the SEC’s website at www.sec.gov.

FORM OF DEPUTY GENERAL COUNSEL’S OPINION

1. Each of the Partnership Entities 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 Partnership Entities (other than the Enterprise Parties) 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 Partnership Entities (other than the Enterprise Parties) 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). Except as described in each of the Pricing Disclosure Package and the Prospectus, EPO and/or the Partnership, as the case may be, directly or indirectly, owns the shares of capital stock, partnership interests or membership interests, as applicable, in each of the Partnership Entities (other than the Enterprise Parties and the General Partner) as set forth on Schedule III to the Underwriting Agreement, free and clear of any lien, charge, encumbrance (other than contractual restrictions on transfer contained in the applicable constituent documents), security interest, restriction upon voting or any other claim of any third party.

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 Partnership Entities, there are no outstanding options or warrants to purchase any partnership interests, membership interests or capital stock in any Partnership Entity.

4. Each of the Enterprise Parties has all requisite right, power and authority to execute and deliver the Underwriting Agreement and to perform its obligations thereunder. The

B-1

Partnership and EPO have all requisite partnership or limited liability company power and authority to issue, sell and deliver the Securities in accordance with and upon the terms and conditions set forth in the Underwriting Agreement, the Indenture, the Registration Statement, the Pricing Disclosure Package and the Prospectus. All action required to be taken by the Enterprise Parties or any of their security holders, partners or members for (i) the due and proper authorization, execution and delivery of the Underwriting Agreement, the Indenture and the Securities, (ii) the consummation of the transactions contemplated thereby and (iii) the authorization, issuance, sale and delivery of the Securities have been duly and validly taken.

Exhibit 99.1

DESCRIPTION OF THE NOTES

Set forth below is a description of the specific terms of the notes. This description supplements, and should be read together with, the description of the general terms and provisions of the junior subordinated notes set forth in the accompanying prospectus under the caption “Description of Debt Securities.” The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the description in the accompanying prospectus and the Indenture (as defined below).

General

Each series of the notes will be issued as a series of junior subordinated notes under an Indenture dated as of October 4, 2004, as amended and supplemented by the Tenth Supplemental Indenture thereto, dated as of June 30, 2007, and as further amended and supplemented by the Twenty-Ninth Supplemental Indenture, to be dated the date of the closing of this offering (such indenture, as so amended and supplemented being referred to herein as the “Indenture”), among us, the Parent Guarantor and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The non-call 5 notes will initially be issued in the aggregate principal amount of $700,000,000. The non-call 10 notes will initially be issued in the aggregate principal amount of $1,000,000,000. With respect to the notes of each series, we may, at any time and without the consent of the holders of the notes of such series, issue additional notes of such series having the same ranking and the same interest rate, maturity and other terms as the notes of such series (except for the public offering price and issue date and the initial interest accrual date and initial interest payment date, if applicable). Any additional notes having such similar terms, together with the applicable series of notes offered hereby, will be fungible and constitute a single series of junior subordinated notes under the Indenture.

Unless earlier redeemed, the entire principal amount of the non-call 5 notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on August 16, 2077, and the entire principal amount of the non-call 10 notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on August 16, 2077. The notes are not subject to any sinking fund provision. The notes are available for purchase in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

Interest

Fixed Rate Period

The non-call 5 notes will bear interest at 4.875% per year during the Non-Call 5 Notes Fixed Rate Period. Subject to our right to defer interest payments as described below, interest on the non-call 5 notes will be payable semi-annually in arrears on February 16 and August 16 of each year, beginning on February 16, 2018. The amount of interest payable for any semi-annual interest accrual period during the Non-Call 5 Notes Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The non-call 10 notes will bear interest at 5.250% per year during the Non-Call 10 Notes Fixed Rate Period. Subject to our right to defer interest payments as described below, interest on the non-call 10 notes will be payable semi-annually in arrears on February 16 and August 16 of each year, beginning on February 16, 2018. The amount of interest payable for any semi-annual interest accrual period during the Non-Call 10 Notes Fixed Rate Period will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Floating Rate Period

The non-call 5 notes will bear interest during the Non-Call 5 Notes Floating Rate Period at the Three-Month LIBOR Rate plus 298.6 basis points (2.986%), reset quarterly. Subject to our right to defer interest payments as described below, interest on the non-call 5 notes will be payable quarterly in arrears on February 16, May 16, August 16 and November 16 of each year beginning on November 16, 2022. Each of such interest payment dates is

also referred to herein as a “Non-Call 5 Notes LIBOR Rate Reset Date.” The amount of interest payable for any quarterly interest accrual period during the Non-Call 5 Notes Floating Rate Period will be computed on the basis of the actual number of days elapsed during that quarterly interest period (determined by including the first day of the interest period and excluding the last day) divided by 360.

The non-call 10 notes will bear interest during the Non-Call 10 Notes Floating Rate Period at the Three-Month LIBOR Rate plus 303.3 basis points (3.033%), reset quarterly. Subject to our right to defer interest payments as described below, interest on the non-call 10 notes will be payable quarterly in arrears on February 16, May 16, August 16 and November 16 of each year beginning on November 16, 2027. Each of such interest payment dates is also referred to herein as a “Non-Call 10 Notes LIBOR Rate Reset Date.” The amount of interest payable for any quarterly interest accrual period during the Non-Call 10 Notes Floating Rate Period will be computed on the basis of the actual number of days elapsed during that quarterly interest period (determined by including the first day of the interest period and excluding the last day) divided by 360.

See “—Determining the Floating Rate” and “Risk Factors—Uncertainty relating to the LIBOR calculation process and potential phasing out of LIBOR after 2021 may adversely affect the value of the notes.”

General

Interest on the notes will be payable to the person in whose name such note is registered at the close of business (i) on the Business Day immediately preceding each interest payment date if the notes are in book-entry only form or (ii) on the 15th calendar day preceding such interest payment date if the notes are not in book-entry only form (whether or not a Business Day), provided that interest payable at maturity or on a redemption date will be paid to the person to whom principal is payable. If interest payments are deferred or otherwise not paid, they will accrue and compound until paid at a rate equal to the interest rate then applicable to the notes. In this prospectus supplement, the term “interest” includes interest payments and interest on interest payments accrued but not paid on the applicable interest payment date.

“Business Day” means a day other than (i) a Saturday or Sunday, (ii) a day on which banks in New York, New York are authorized or obligated by law or executive order to remain closed or (iii) a day on which the Trustee’s corporate trust office is closed for business.

During the Non-Call 5 Notes Fixed Rate Period, in the case of the non-call 5 notes, and during the Non-Call 10 Notes Fixed Rate Period, in the case of the non-call 10 notes, if an interest payment date or a redemption date of the notes falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the interest payment date or the redemption date, as applicable.

During the Non-Call 5 Notes Floating Rate Period, in the case of the non-call 5 notes and during the Non-Call 10 Notes Floating Rate Period, in the case of the non-call 10 notes, if any interest payment date, other than a redemption date or the maturity date of the notes, falls on a day that is not a Business Day, the interest payment date will be postponed to the next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the interest payment date will be the immediately preceding Business Day. Also, if a redemption date or the maturity date of either series of notes falls on a day that is not a Business Day, the payment of interest and principal will be made on the next succeeding Business Day, and no interest on such payment will accrue for the period from and after the redemption date or the maturity date, as applicable. During the Non-Call 5 Notes Floating Rate Period, if any Non-Call 5 Notes LIBOR Rate Reset Date falls on a day that is not a Business Day, the Non-Call 5 Notes LIBOR Rate Reset Date will be postponed to the next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the Non-Call 5 Notes LIBOR Rate Reset Date will be the immediately preceding Business Day. During the Non-Call 5 Notes Floating Rate Period, the interest rate in effect on any Non-Call 5 Notes LIBOR Rate Reset Date will be the applicable interest rate as reset on that date, and the interest rate applicable to any other day will be the interest rate as reset

on the immediately preceding Non-Call 5 Notes LIBOR Rate Reset Date. During the Non-Call 10 Notes Floating Rate Period, if any Non-Call 10 Notes LIBOR Rate Reset Date falls on a day that is not a Business Day, the Non-Call 10 Notes LIBOR Rate Reset Date will be postponed to the next day that is a Business Day, except that if that Business Day is in the next succeeding calendar month, the Non-Call 10 Notes LIBOR Rate Reset Date will be the immediately preceding Business Day. During the Non-Call 10 Notes Floating Rate Period, the interest rate in effect on any Non-Call 10 Notes LIBOR Rate Reset Date will be the applicable interest rate as reset on that date, and the interest rate applicable to any other day will be the interest rate as reset on the immediately preceding Non-Call 10 Notes LIBOR Rate Reset Date.

Determining the Floating Rate

The “Three-Month LIBOR Rate” means the rate determined in accordance with the following provisions:

On the LIBOR Interest Determination Date (as defined below), the Calculation Agent (as defined below) will determine the Three-Month LIBOR Rate which will be the rate for deposits in U.S. dollars having a three-month maturity which appears on the Reuters Page LIBOR01 (as defined below) as of 11:00 a.m., London time, on the LIBOR Interest Determination Date.

If no rate appears on Reuters Page LIBOR01 on the LIBOR Interest Determination Date, the Calculation Agent will request the principal London offices of four major reference banks in the London Inter-Bank Market to provide it with their offered quotations for deposits in U.S. dollars in a principal amount of not less than $1,000,000 for the period of three months, commencing on the Non-Call 5 Notes LIBOR Rate Reset Date (in the case of the non-call 5 notes) or the Non-Call 10 Notes LIBOR Rate Reset Date (in the case of the non-call 10 notes), to prime banks in the London Inter-Bank Market at approximately 11:00 a.m., London time, on that LIBOR Interest Determination Date and in a principal amount that is representative for a single transaction in U.S. dollars in that market at that time. If at least two quotations are provided, then the Three-Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one hundredth (0.01) of a percent) of those quotations. If fewer than two quotations are provided, then the Three-Month LIBOR Rate will be the average (rounded, if necessary, to the nearest one hundredth (0.01) of a percent) of the rates quoted at approximately 11:00 a.m., Eastern Time, on the LIBOR Interest Determination Date by three major banks in New York City selected by the Calculation Agent for loans in U.S. dollars to leading European banks, having a three-month maturity and in a principal amount of not less than $1,000,000. If the banks selected by the Calculation Agent are not providing quotations in the manner described by this paragraph, the rate for the quarterly interest period following the LIBOR Interest Determination Date will be the rate in effect on that LIBOR Interest Determination Date.

“Reuters Page LIBOR01” means the display designated as Reuters LIBOR01 on the Reuters service (or such other page as may replace the Reuters Page LIBOR01 on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying rates or prices comparable to the London Interbank Offered rate for U.S. dollar deposits).

“LIBOR Interest Determination Date” means (i) with respect to the non-call 5 notes, the second LIBOR Business Day (as defined below) preceding each Non-Call 5 Notes LIBOR Rate Reset Date and (ii) with respect to the non-call 10 notes, the second LIBOR Business Day (as defined below) preceding each Non-Call 10 Notes LIBOR Rate Reset Date.

“LIBOR Business Day” means any Business Day on which dealings in deposits in U.S. dollars are transacted in the London Inter-Bank market.

“Calculation Agent” means Wells Fargo Bank, National Association or its successor appointed by us, acting as calculation agent.

Option to Defer Interest Payments

So long as no Event of Default under the Indenture has occurred and is continuing, at our option, we may, on one or more occasions, defer payment of all or part of the current and accrued interest otherwise due on each series of notes by extending the interest payment period for up to 10 consecutive years (each period, commencing on the date that the first such interest payment would otherwise have been made, an “Optional Deferral Period”). A deferral of interest payments may not extend beyond the maturity date of the applicable series of notes or end on a day other than an interest payment date. Any deferred interest on a series of notes will accrue additional interest at the interest rate then applicable to such notes from the applicable interest payment date to the date of payment (such deferred interest and additional interest accrued thereon, “Additional Interest”), to the extent permitted under applicable law. No interest will be due and payable on the notes of such series until the end of an Optional Deferral Period, except upon a redemption of such notes during such Optional Deferral Period.

At the end of an Optional Deferral Period or on any redemption date, we will be obligated to pay all accrued and unpaid interest, including any Additional Interest. Once we pay all accrued and unpaid interest payments on a series of notes, including any Additional Interest, we can again defer interest payments on such notes as described above, but not beyond the maturity date of such notes.

We are required to provide to the Trustee written notice of any optional deferral of interest at least 10 and not more than 60 Business Days prior to the earlier of (1) the next applicable interest payment date or (2) the date, if any, upon which it is required to give notice of such interest payment date or the record date therefor to the New York Stock Exchange or any applicable self-regulatory organization. In addition, we are required to deliver to the Trustee an officers’ certificate stating that no default or Event of Default shall have occurred and be continuing. Subject to receipt of the officers’ certificate, the Trustee is required to promptly forward such notice to each holder of record of the applicable series of notes.

Certain Limitations During an Optional Deferral Period

During an Optional Deferral Period, subject to the exceptions noted below, we shall not:

•

declare, pay or make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of our equity securities, or

•

make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by us that rank equally with or junior to the notes.

None of the foregoing, however, shall restrict:

•

any of the actions described in the preceding sentence resulting from any reclassification of our equity securities or the exchange or conversion of one class or series of our equity securities for another class or series of our equity securities;

•

the purchase of fractional interests in our equity securities pursuant to the conversion or exchange provisions of such equity security or the security being converted or exchanged;

•

payments or distributions payable in our equity securities;

•

redemptions, purchases or other acquisitions of our equity securities in connection with any employment contract, incentive plan, benefit plan or other similar arrangement of us or any of our subsidiaries or in connection with a dividend reinvestment plan; or

•

any declaration of a distribution in connection with implementation of any rights plan, or the issuance of rights, equity security or other property under any such plan, or the redemption, repurchase or other acquisition of any such rights pursuant thereto.

Optional Redemption

At any time and from time to time on or after August 16, 2022, in the case of the non-call 5 notes, and at any time and from time to time on or after August 16, 2027, in the case of the non-call 10 notes, the notes will be subject to redemption at our option in whole or in part upon not less than 30 nor more than 60 days’ notice, at a redemption price equal to 100% of the principal amount of the notes being redeemed plus accrued and unpaid interest (including any Additional Interest) on the notes being redeemed to the redemption date.

If notice of redemption is given as aforesaid, the notes to be redeemed will, on the redemption date, become due and payable at the redemption price together with any accrued and unpaid interest thereon, and from and after such date (unless we have defaulted in the payment of the redemption price and accrued interest) such notes shall cease to bear interest. See “Description of our Debt Securities” in the accompanying prospectus.

We may also redeem the non-call 5 notes before August 16, 2022 and redeem the non-call 10 notes before August 16, 2027, (i) in whole, but not in part, if certain changes in tax laws, regulations or interpretations occur, at the redemption price and under the circumstances described below under “—Right to Redeem Upon a Tax Event” and (ii) in whole, but not in part, if a rating agency makes certain changes in the equity credit criteria for securities such as the notes, at the redemption price and under the circumstances described below under “—Right to Redeem Upon a Rating Agency Event.”

Subject to the foregoing and to applicable law (including, without limitation, United States federal securities laws), we and our affiliates may, at any time and from time to time, purchase outstanding notes by tender, in the open market or by private agreement.

Right to Redeem Upon a Tax Event

Before August 16, 2022, in the case of the non-call 5 notes, and before August 16, 2027, in the case of the non-call 10 notes, we may redeem, upon a redemption notice, in whole but not in part, the notes following the occurrence of a Tax Event (as defined below), at 100% of their principal amount plus any accrued and unpaid interest thereon (including any Additional Interest) to the redemption date.

A “Tax Event” happens when we have received an opinion of counsel experienced in tax matters that, as a result of:

•

any amendment to, clarification of, or change, including any announced prospective change, in the laws or treaties of the United States or any of its political subdivisions or taxing authorities, or any regulations under those laws or treaties;

•

an administrative action, which means any judicial decision or any official administrative pronouncement, ruling, regulatory procedure, notice or announcement including any notice or announcement of intent to issue or adopt any administrative pronouncement, ruling, regulatory procedure or regulation;

•

any amendment to, clarification of, or change in the official position or the interpretation of any administrative action or judicial decision or any interpretation or pronouncement that provides for a position with respect to an administrative action or judicial decision that differs from the previously generally accepted position, in each case by any legislative body, court, governmental authority or regulatory body, regardless of the time or manner in which that amendment, clarification or change is introduced or made known; or

•

a threatened challenge asserted in writing in connection with our audit or an audit of any of our subsidiaries, or a publicly-known threatened challenge asserted in writing against any other taxpayer that has raised capital through the issuance of securities that are substantially similar to the notes,

which amendment, clarification or change is effective or the administrative action is taken or judicial decision, interpretation or pronouncement is issued or threatened challenge is asserted or becomes publicly-known after

the date of the original issuance of the notes, there is more than an insubstantial risk that interest payable by us on the notes is not deductible, or within 90 days would not be deductible, in whole or in part, by us for U.S. federal income tax purposes.

Right to Redeem Upon a Rating Agency Event

Before August 16, 2022, in the case of the non-call 5 notes, and before August 16, 2027, in the case of the non-call 10 notes, we may redeem, upon a redemption notice, in whole but not in part, the notes following the occurrence of a Rating Agency Event (as defined below), at 102% of their principal amount plus any accrued and unpaid interest thereon (including any Additional Interest) to the redemption date.

“Rating Agency Event” means a change to the methodology or criteria that were employed by an applicable nationally recognized statistical rating organization for purposes of assigning equity credit to securities such as the notes on the date of original issuance of the notes (the “current methodology”), which change either (i) shortens the period of time during which equity credit pertaining to the notes would have been in effect had the current methodology not been changed or (ii) reduces the amount of equity credit assigned to the notes as compared with the amount of equity credit that such rating agency had assigned to the notes as of the date of original issuance thereof.

Ranking; Subordination

Each series of the notes will rank pari passu in right of payment with the other series of the notes and with the following subordinated debt securities (our “Existing Subordinated Notes”):

•

Junior Subordinated Notes A, fixed/variable-rate, due August 2066;

•

Junior Subordinated Notes C, fixed/variable-rate, due June 2067; and

•

Junior Subordinated Notes B, fixed/variable-rate, due January 2068.

Our payment obligations under the notes will, to the extent provided in the Indenture, be subordinated to the prior payment in full of all of our present and future Senior Indebtedness, as defined below. The notes will rank senior in right of payment to all of our present and future equity securities.

The holders of our Senior Indebtedness will be entitled to receive payment in full of such Senior Indebtedness before holders of the notes will receive any payment of principal, premium or interest with respect to the notes:

•

upon any payment or distribution of our assets to our creditors in connection with our total or partial liquidation or dissolution; or

•

in a bankruptcy, receivership or similar proceeding relating to us or our property.

In these circumstances, until our Senior Indebtedness is paid in full, any distribution to which holders of notes would otherwise be entitled will be made to the holders of Senior Indebtedness, except that such holders may receive units representing limited partner interests and debt securities that are subordinated to Senior Indebtedness to at least the same extent as the notes.

If we do not pay any principal, premium or interest with respect to Senior Indebtedness within any applicable grace period (including at maturity), or any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms, we may not:

•

make any payments of principal, premium, if any, or interest with respect to the notes;

•

make any deposit for the purpose of defeasance of the notes; or

•

purchase, redeem or otherwise retire any of the notes,

unless, in any case,

•

the default has been cured or waived and the declaration of acceleration has been rescinded;

•

the Senior Indebtedness has been paid in full; or

•

we and the Trustee receive written notice approving the payment from the representatives of each issue of Designated Senior Indebtedness (as defined below).

During the continuance of any Senior Indebtedness default, other than a default described in the immediately preceding paragraph, that may cause the maturity of any Designated Senior Indebtedness to be accelerated immediately without further notice, other than any notice required to effect such acceleration, or the expiration of any applicable grace periods, we may not make payments on the notes for a period called the “Payment Blockage Period.” A Payment Blockage Period will commence on the receipt by us and the Trustee of written notice of the default, called a “Blockage Notice,” from the representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period, and will expire 179 days thereafter.

Generally, “Designated Senior Indebtedness” will include any issue of Senior Indebtedness of at least $100 million and any issue of Senior Indebtedness designated by us or Enterprise Parent at the time of issuance as Designated Senior Indebtedness.

The Payment Blockage Period may be terminated before its expiration:

•

by written notice from the person or persons who gave the Blockage Notice;

•

by repayment in full in cash of the Senior Indebtedness with respect to which the Blockage Notice was given; or

•

if the default giving rise to the Payment Blockage Period is no longer continuing.

Unless the holders of Designated Senior Indebtedness shall have accelerated the maturity of the Senior Indebtedness, we may resume payments on the notes after the expiration of the Payment Blockage Period.

If (1) we do not pay principal, premium or interest with respect to Senior Indebtedness within any applicable grace period, (2) any other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms or (3) we receive a Blockage Notice, then, notwithstanding any notice requirements necessary to invoke an Optional Deferral Period, we may elect to defer payment of all or part of the current and accrued interest otherwise due on the notes on an interest payment date by giving notice to the Trustee of such election not later than the time we must remit payment of interest on the notes to the Trustee on such interest payment date. Any such notice will be forwarded promptly by the Trustee to each holder of record of the notes. However, we may only exercise this right if we are otherwise entitled to elect to optionally defer payment of interest on the notes as described under “—Optional Deferral of Interest.”

Generally, not more than one Blockage Notice may be given in any period of 360 consecutive days. The total number of days during which any one or more Payment Blockage Periods are in effect, however, may not exceed an aggregate of 179 days during any period of 360 consecutive days.

After all Senior Indebtedness is paid in full and until the notes are paid in full, holders of the notes will be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness.

Because of the subordination, in the event of our insolvency, our creditors who are holders of Senior Indebtedness, as well as certain of our general creditors, may recover more, ratably, than the holders of the notes.

The term “Senior Indebtedness” as used in this section includes our obligations in respect of the principal of, any interest and premium, if any, on and any other payments in respect of any of the following, whether currently outstanding or hereafter created or incurred:

•

indebtedness for borrowed money;

•

indebtedness evidenced by securities, bonds, notes and debentures, including any of the same that are subordinated in right of payment (other than the notes of each series), issued under credit agreements, indentures or other similar instruments, and other similar instruments;

•

obligations arising from or with respect to guarantees and direct credit substitutes (other than the Guarantee);

•

obligations arising from or with respect to hedges and derivative products (including, but not limited to, interest rate, commodity and foreign exchange contracts);

•

capitalized lease obligations;

•

obligations arising from or with respect to any letter of credit, banker’s acceptance, security purchase facility, cash management arrangement, or similar credit transactions;

•

operating leases (but only to the extent the terms of such leases expressly provide that the same constitute “Senior Indebtedness”);

•

guarantees of any of the foregoing; and

•

any modifications, refundings, deferrals, renewals or extensions of any of the foregoing or any other evidence of indebtedness issued in exchange therefor,

but does not include our obligations in respect of:

•

trade accounts payable;

•

any indebtedness incurred for the purchase of goods or materials or for services obtained in the ordinary course of business to the extent that the same is incurred from, and owed to, the vendor of such goods or materials or the provider of such services;

•

any indebtedness which by its terms is expressly made equal in rank and payment with or subordinated to the notes;

•

indebtedness owed by us to our majority-owned subsidiaries; and

•

our Existing Subordinated Notes.

The obligations under the notes will be structurally subordinated to all indebtedness and other liabilities of our subsidiaries and unconsolidated affiliates. In the event of an insolvency, liquidation, bankruptcy proceeding or other reorganization of any such entity, all of the existing and future liabilities of such entity, including any claims of lessors under capital and operating leases, trade creditors and holders of preferred stock or units of that entity have the right to be satisfied prior to receipt by us of any payment on account of our status as an equity owner of such entity. At June 30, 2017, the direct indebtedness of Enterprise that is senior to the notes totaled approximately $22.1 billion, and the direct indebtedness of Enterprise that is pari passu with the notes (i.e., subordinated debt) totaled approximately $1.5 billion. At June 30, 2017, the indebtedness of our subsidiaries and unconsolidated affiliates totaled approximately $69.2 million. Moreover, the Indenture does not limit our ability or the ability of our subsidiaries or unconsolidated affiliates to incur additional indebtedness and other obligations, including indebtedness and other obligations that rank senior in priority of payment to or pari passu with the notes.

Certain Covenants

No Limitations on Liens. Holders of the notes will not have the benefit of and will not be entitled to enforce the covenant in the Indenture restricting the ability of the Parent Guarantor, Enterprise and their

respective majority-owned subsidiaries to, create, assume, incur or suffer to exist any mortgage, lien, security interest, pledge, charge or other encumbrance other than Permitted Liens, as described in “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

No Restriction on Sale-Leasebacks. Holders of the notes will not have the benefit of and will not be entitled to enforce the covenant in the Indenture restricting the ability of the Parent Guarantor, Enterprise and their respective majority-owned subsidiaries to enter into Sale-Leaseback Transactions, as described in “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

Merger, Consolidation or Sale of Assets. Each of the Parent Guarantor and Enterprise will be subject to the restriction in the Indenture governing its ability to consolidate with or sell, lease, convey all or substantially all of its assets to, or merge with or into, any partnership, limited liability company or corporation, as described in “Description of Debt Securities—Certain Covenants” in the accompanying prospectus.

Non-Recourse Obligation

The notes are obligations of Enterprise and, to the extent provided in the Guarantee, are guaranteed by Enterprise Parent. Pursuant to the Indenture, holders of the notes will not have recourse against our general partner, the general partner of Enterprise Parent, any other partner of, or other person that owns an equity interest directly or indirectly in, us, Enterprise Parent or such general partners or against any of their respective past, present or future directors, managers, officers, employees, agents, members or partners. In addition, holders of the notes by their purchase and holding thereof acknowledge the separateness of us, Enterprise Parent and our respective general partners from each other and from any other persons, including Enterprise GP Holdings L.P. and its affiliates and EPCO, Inc. and its affiliates and that we, Enterprise Parent and our respective general partners have assets and liabilities that are separate from those of other persons, including Enterprise GP Holdings L.P. and its affiliates and EPCO Inc. and its affiliates.

Events of Default

The following are the “Events of Default” with respect to the notes of each series, which are modified from the events of default described in the accompanying prospectus:

•

failure to pay principal of, or premium, if any, on or interest on the notes of such series when due at maturity or earlier redemption;

•

failure to pay interest on the notes of such series (including Additional Interest) when due and payable (other than at maturity or upon earlier redemption) that continues for 30 days (subject to our right to optionally defer interest payments); or

•

certain events of bankruptcy, insolvency or reorganization involving us or Enterprise Parent.

With respect to the notes, the term “Default” means the following event: default in the performance or breach of any covenant or warranty of us in the Indenture (other than (i) a covenant or warranty a default in whose performance or whose breach is addressed in the preceding paragraph or (ii) certain other covenants and warranties inapplicable to the notes), and continuance of such default or breach for a period of 90 days after specified written notice to us by the Trustee, or to us and the Trustee by the holders of at least 25% in principal amount of the outstanding notes.

Upon the occurrence and continuance of a Default, the Trustee and the holders of the notes will have the same rights and remedies, and will be subject to the same limitations, restrictions, protections and exculpations, and we will be subject to the same obligations and restrictions, in each case, as would apply if such Default were an Event of Default or an event which after notice or lapse of time or both would become an Event of Default; provided that the principal of and accrued interest on the notes may not be declared immediately due and payable

by reason of the occurrence and continuation of a Default, and any notice of declaration or acceleration based on such Default will be null and void with respect to the notes; provided, further that in case a Default has occurred and is continuing, the Trustee will not be subject to the requirement to exercise, with respect to the notes, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs, unless an Event of Default has occurred and is continuing.

Parent Guarantee

The Parent Guarantor will fully and unconditionally guarantee on an unsecured and junior subordinated basis the full and prompt payment of principal of, premium, if any, and interest on the notes, when and as the same become due and payable (other than during an Optional Deferral Period), whether at stated maturity, upon redemption, by declaration of acceleration or otherwise. The Parent Guarantor’s obligations under such guarantee (the “Guarantee”) will, to the extent provided in the Indenture, be subordinated to the prior payment in full of all present and future Senior Indebtedness of the Parent Guarantor, as defined below. The Parent Guarantor’s obligations under the Guarantee will rank senior in right of payment to all of its present and future equity securities, including its common units.

The holders of the Parent Guarantor’s Senior Indebtedness will be entitled to receive payment in full of such Senior Indebtedness before holders of the notes receive from the Parent Guarantor any payment of principal, premium or interest with respect to the notes:

•

upon any payment or distribution of the Parent Guarantor’s assets to its creditors in connection with the Parent Guarantor’s total or partial liquidation or dissolution; or

•

in a bankruptcy, receivership or similar proceeding relating to the Parent Guarantor or its property.

In these circumstances, until the Parent Guarantor’s Senior Indebtedness is paid in full, any distribution to which holders of notes would otherwise be entitled under the Guarantee will be made to the holders of its Senior Indebtedness, except that such holders may receive equity securities and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the Guarantee.

If the Parent Guarantor does not pay any principal, premium or interest with respect to its Senior Indebtedness within any applicable grace period (including at maturity), or any other default on its Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms, the Parent Guarantor may not:

•

make any payments under the Guarantee of principal, premium, if any, or interest with respect to the notes;

•

make any deposit under the Guarantee for the purpose of defeasance of the notes; or

•

advance monies under the Guarantee to repurchase, redeem or otherwise retire any of the notes,

unless, in any case,

•

the default has been cured or waived and the declaration of acceleration has been rescinded;

•

the Senior Indebtedness has been paid in full; or

•

the Parent Guarantor and the Trustee receive written notice approving the payment from the representatives of each issue of Designated Senior Indebtedness (as defined below).

a period called the “Payment Blockage Period.” A Payment Blockage Period will commence on the receipt by the Parent Guarantor and the Trustee of written notice of the default, called a “Blockage Notice,” from the representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period, and will expire 179 days thereafter.

The Payment Blockage Period may be terminated before its expiration:

•

by written notice from the person or persons who gave the Blockage Notice;

•

by repayment in full in cash of the Senior Indebtedness with respect to which the Blockage Notice was given; or

•

if the default giving rise to the Payment Blockage Period is no longer continuing.

Unless the holders of the Designated Senior Indebtedness shall have accelerated the maturity of the Senior Indebtedness, the Parent Guarantor may resume making payments under the Guarantee after the expiration of the Payment Blockage Period.

Because of the subordination, in the event of the Parent Guarantor’s insolvency, its creditors who are holders of Senior Indebtedness, as well as certain of its general creditors, may recover more, ratably, than the holders of the notes will recover under the Guarantee.

The term “Senior Indebtedness” as used in this section includes the Parent Guarantor’s obligations in respect of the principal of, any interest and premium, if any, on and any other payments in respect of any of the following, whether currently outstanding or hereafter created or incurred:

•

indebtedness for borrowed money;

•

indebtedness evidenced by securities, bonds, notes and debentures, including any of the same that are subordinated, issued under credit agreements, indentures or other similar instruments, and other similar instruments;

•

obligations arising from or with respect to guarantees and direct credit substitutes other than the Parent Guarantor’s obligations under the Guarantee;

•

obligations arising from or with respect to hedges and derivative products (including, but not limited to, interest rate, commodity, and foreign exchange contracts);

•

capitalized lease obligations;

•

obligations arising from or with respect to any letter of credit, banker’s acceptance, security purchase facility, cash management arrangement or similar credit transactions;

•

operating leases (but only to the extent the terms of such leases expressly provide that the same constitute “Senior Indebtedness”);

•

guarantees of any of the foregoing; and

•

any modifications, refundings, deferrals, renewals or extensions of any of the foregoing or any other evidence of indebtedness issued in exchange therefor,

but does not include the Parent Guarantor’s obligations in respect of:

•

trade accounts payable;

•

any indebtedness which by its terms is expressly made equal in rank and payment with or subordinated to the Parent Guarantor’s obligations under the Guarantee;

•

indebtedness owed by the Parent Guarantor to its majority-owned subsidiaries; and

•

the Parent Guarantor’s guarantee of our Existing Subordinated Notes.

The Guarantee will rank pari passu with Enterprise Parent’s guarantee of our Existing Subordinated Notes.

The obligations under the Guarantee will be structurally subordinated to all indebtedness and other liabilities of the Parent Guarantor’s subsidiaries and unconsolidated affiliates. In the event of an insolvency, liquidation, bankruptcy proceeding or other reorganization of any such entity all of the existing and future liabilities of such entity, including any claims of lessors under capital and operating leases, trade creditors and holders of preferred stock or units of that entity have the right to be satisfied prior to receipt by the Parent Guarantor of any payment on account of its status as an equity owner of such entity. Moreover, the Guarantee does not limit the Parent Guarantor or any of its subsidiaries or unconsolidated affiliates from incurring or issuing other secured or unsecured debt, including Senior Indebtedness. Accordingly, claimants under the Guarantee should look only to the Parent Guarantor and not to any of its subsidiaries or unconsolidated affiliates for payments under the Guarantee.

Agreement by Holders to Certain Tax Treatment

Each holder of the notes will, by accepting the notes or a beneficial interest therein, be deemed to have agreed that the holder intends that the notes constitute indebtedness and will treat the notes as indebtedness for all U.S. federal, state and local tax purposes.

Book-Entry Only Issuance; The Depository Trust Company

DTC will act as the initial securities depositary for the notes. The notes will be issued only as fully registered securities registered in the name of Cede & Co., DTC’s nominee, or such other name as may be requested by an authorized representative of DTC. One or more fully registered global notes certificates will be issued, representing in the aggregate the total principal amount of notes, and will be deposited with the Trustee on behalf of DTC. Investors may hold interests in the notes through DTC if they are participants in DTC or indirectly through organizations that are participants in DTC, including Euroclear Bank SA/NV, as operator of the Euroclear system, or Clearstream Banking S.A., Luxembourg (“Clearstream”).

DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments (from over 100 countries) that DTC’s participants (“Direct

Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). The DTC rules applicable to its Direct and Indirect Participants are on file with the United States Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com. The contents of such website do not constitute part of this prospectus supplement.

Purchases of notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the notes on DTC’s records. The ownership interest of each actual purchaser of each note (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchases. Beneficial Owners, however, are expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which the Beneficial Owners purchased notes. Transfers of ownership interests in the notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in notes, except in the event that use of the book-entry system for the notes is discontinued.

To facilitate subsequent transfers, all notes deposited by Direct Participants with DTC are registered in the name of DTC’s nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any changes in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the notes. DTC’s records reflect only the identity of the Direct Participants to whose accounts such notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices will be sent to DTC. If less than all of the notes are being redeemed, DTC’s practice is to determine by lot the amount of interest of each Direct Participant in such notes to be redeemed.

Although voting with respect to the notes is limited, in those cases where a vote is required, neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the notes unless authorized by a Direct Participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts the notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Payments on the notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the Trustee on the relevant payment date in accordance with their respective holdings shown on DTC’s records. Payments by Direct or Indirect Participants to Beneficial

Owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers registered in “street name,” and will be the responsibility of such Direct or Indirect Participant and not of DTC or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is our responsibility, disbursement of such payments to Direct Participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants.

Except in the limited cases provided in the Indenture, a Beneficial Owner of a global note will not be entitled to receive physical delivery of notes. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the notes. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global note.

DTC may discontinue providing its services as securities depositary with respect to the notes at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor securities depositary is not obtained, notes certificates will be required to be printed and delivered to the holders of record. Additionally, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary) with respect to the notes. We understand, however, that under current industry practices, DTC would notify its Direct and Indirect Participants of our decision, but will only withdraw beneficial interests from a global note at the request of each Direct or Indirect Participant. In that event, certificates for the notes will be printed and delivered to the applicable Direct or Indirect Participant.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but neither we nor any underwriter take any responsibility for the accuracy thereof. Neither we nor any underwriter have any responsibility for the performance by DTC or its Direct or Indirect Participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

Global Clearance and Settlement Procedures

Secondary market trading between Clearstream participants and/or Euroclear system participants will occur in the ordinary way in accordance with the applicable rules and operating procedures of Clearstream and the Euroclear system, as applicable. Cross-market transfers between persons holding directly or indirectly through DTC on the one hand, and directly or indirectly through Clearstream participants or Euroclear system participants on the other, will be effected through DTC in accordance with DTC rules on behalf of the relevant European international clearing system by its U.S. depositary; however, such cross-market transactions will require delivery of instructions to the relevant European international clearing system by the counterparty in such system in accordance with its rules and procedures and within its established deadlines (European time). The relevant European international clearing system will, if the transaction meets its settlement requirements, deliver instructions to its U.S. depositary to take action to effect final settlement on its behalf by delivering or receiving securities in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Clearstream participants and Euroclear system participants may not deliver instructions directly to their respective U.S. depositaries. Because of time-zone differences, credits of notes received in Clearstream or the Euroclear system as a result of a transaction with a DTC participant will be made during subsequent securities settlement processing and dated the business day following the DTC settlement date. Such credits or any transactions in such notes settled during such processing will be reported to the relevant Euroclear system participant or Clearstream participant on such business day. Cash received in Clearstream or the Euroclear system as a result of sales of the notes by or through a Clearstream participant or a Euroclear system participant to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Clearstream or the Euroclear system cash account only as of the business day following settlement in DTC.

DESCRIPTION OF DEBT SECURITIES

In this Description of Debt Securities references to the “Issuer” mean only Enterprise Products Operating LLC (successor to Enterprise Products Operating L.P.) and not its subsidiaries. References to the “Guarantor” mean only Enterprise Products Partners L.P. and not its subsidiaries. References to “we” and “us” mean the Issuer and the Guarantor collectively.

The debt securities will be issued under an Indenture dated as of October 4, 2004, as amended by the Tenth Supplemental Indenture, dated as of June 30, 2007, and as further amended by one or more additional supplemental indentures (collectively, the “Indenture”), among the Issuer, the Guarantor, and Wells Fargo Bank, National Association, as trustee (the “Trustee”). The terms of the debt securities will include those expressly set forth in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). Capitalized terms used in this Description of Debt Securities have the meanings specified in the Indenture.

This Description of Debt Securities is intended to be a useful overview of the material provisions of the debt securities and the Indenture. Since this Description of Debt Securities is only a summary, you should refer to the Indenture for a complete description of our obligations and your rights.

General

The Indenture does not limit the amount of debt securities that may be issued thereunder. Debt securities may be issued under the Indenture from time to time in separate series, each up to the aggregate amount authorized for such series. The debt securities will be general obligations of the Issuer and the Guarantor and may be subordinated to Senior Indebtedness of the Issuer and the Guarantor. See “— Subordination.”

A prospectus supplement and a supplemental indenture (or a resolution of our Board of Directors and accompanying officers’ certificate) relating to any series of debt securities being offered will include specific terms relating to the offering. These terms will include some or all of the following:

•

the form and title of the debt securities;

•

the total principal amount of the debt securities;

•

the portion of the principal amount which will be payable if the maturity of the debt securities is accelerated;

•

the currency or currency unit in which the debt securities will be paid, if not U.S. dollars;

•

any right we may have to defer payments of interest by extending the dates payments are due whether interest on those deferred amounts will be payable as well;

•

the dates on which the principal of the debt securities will be payable;

•

the interest rate which the debt securities will bear and the interest payment dates for the debt securities;

•

any optional redemption provisions;

•

any sinking fund or other provisions that would obligate us to repurchase or otherwise redeem the debt securities;

•

any changes to or additional Events of Default or covenants;

•

whether the debt securities are to be issued as Registered Securities or Bearer Securities or both; and any special provisions for Bearer Securities;

•

the subordination, if any, of the debt securities and any changes to the subordination provisions of the Indenture; and

•

any other terms of the debt securities.

The prospectus supplement will also describe any material United States federal income tax consequences or other special considerations applicable to the applicable series of debt securities, including those applicable to:

•

Bearer Securities;

•

debt securities with respect to which payments of principal, premium or interest are determined with reference to an index or formula, including changes in prices of particular securities, currencies or commodities;

•

debt securities with respect to which principal, premium or interest is payable in a foreign or composite currency;

•

debt securities that are issued at a discount below their stated principal amount, bearing no interest or interest at a rate that at the time of issuance is below market rates; and

•

variable rate debt securities that are exchangeable for fixed rate debt securities.

At our option, we may make interest payments, by check mailed to the registered holders thereof or, if so stated in the applicable prospectus supplement, at the option of a holder by wire transfer to an account designated by the holder. Except as otherwise provided in the applicable prospectus supplement, no payment on a Bearer Security will be made by mail to an address in the United States or by wire transfer to an account in the United States.

Registered Securities may be transferred or exchanged, and they may be presented for payment, at the office of the Trustee or the Trustee’s agent in New York City indicated in the applicable prospectus supplement, subject to the limitations provided in the Indenture, without the payment of any service charge, other than any applicable tax or governmental charge. Bearer Securities will be transferable only by delivery. Provisions with respect to the exchange of Bearer Securities will be described in the applicable prospectus supplement.

Any funds we pay to a paying agent for the payment of amounts due on any debt securities that remain unclaimed for two years will be returned to us, and the holders of the debt securities must thereafter look only to us for payment thereof.

Guarantee

The Guarantor will unconditionally guarantee to each holder and the Trustee the full and prompt payment of principal of, premium, if any, and interest on the debt securities, when and as the same become due and payable, whether at maturity, upon redemption or repurchase, by declaration of acceleration or otherwise.

Certain Covenants

Except as set forth below or as may be provided in a prospectus supplement and supplemental indenture, neither the Issuer nor the Guarantor is restricted by the Indenture from incurring any type of indebtedness or other obligation, from paying dividends or making distributions on its partnership interests or capital stock or purchasing or redeeming its partnership interests or capital stock. The Indenture does not require the maintenance of any financial ratios or specified levels of net worth or liquidity. In addition, the Indenture does not contain any provisions that would require the Issuer to repurchase or redeem or otherwise modify the terms of any of the debt securities upon a change in control or other events involving the Issuer which may adversely affect the creditworthiness of the debt securities.

Limitations on Liens. The Indenture provides that the Guarantor will not, nor will it permit any Subsidiary to, create, assume, incur or suffer to exist any mortgage, lien, security interest, pledge, charge or other

encumbrance (“liens”) other than Permitted Liens (as defined below) upon any Principal Property (as defined below) or upon any shares of capital stock of any Subsidiary owning or leasing, either directly or through ownership in another Subsidiary, any Principal Property (a “Restricted Subsidiary”), whether owned or leased on the date of the Indenture or thereafter acquired, to secure any indebtedness for borrowed money (“debt”) of the Guarantor or the Issuer or any other person (other than the debt securities), without in any such case making effective provision whereby all of the debt securities outstanding shall be secured equally and ratably with, or prior to, such debt so long as such debt shall be so secured.

In the Indenture, the following terms are given the following meanings:

“Consolidated Net Tangible Assets” means, at any date of determination, the total amount of assets of the Guarantor and its consolidated subsidiaries after deducting therefrom:

(2) value (net of any applicable reserves) of all goodwill, trade names, trademarks, patents and other like intangible assets, all as set forth, or on a pro forma basis would be set forth, on the consolidated balance sheet of the Guarantor and its consolidated subsidiaries for the Guarantor’s most recently completed fiscal quarter, prepared in accordance with generally accepted accounting principles.

(1) the Issuer; or

(2) any corporation, association or other business entity of which more than 50% of the total voting power of the equity interests entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof or any partnership of which more than 50% of the partners’ equity interests (considering all partners’ equity interests as a single class) is, in each case, at the time owned or controlled, directly or indirectly, by the Guarantor, the Issuer or one or more of the other Subsidiaries of the Guarantor or the Issuer or combination thereof.

Notwithstanding the preceding, under the Indenture, the Guarantor may, and may permit any Subsidiary to, create, assume, incur, or suffer to exist any lien (other than a Permitted Lien) upon any Principal Property or capital stock of a Restricted Subsidiary to secure debt of the Guarantor, the Issuer or any other person (other than the debt securities), without securing the debt securities, provided that the aggregate principal amount of all debt then outstanding secured by such lien and all similar liens, together with all Attributable Indebtedness from Sale-Leaseback Transactions (excluding Sale-Leaseback Transactions permitted by clauses (1) through (4), inclusive, of the first paragraph of the restriction on sale-leasebacks covenant described below) does not exceed 10% of Consolidated Net Tangible Assets.

Restriction on Sale-Leasebacks. The Indenture provides that the Guarantor will not, and will not permit any Subsidiary to, engage in the sale or transfer by the Guarantor or any Subsidiary of any Principal Property to a person (other than the Issuer or a Subsidiary) and the taking back by the Guarantor or any Subsidiary, as the case may be, of a lease of such Principal Property (a “Sale-Leaseback Transaction”), unless:

(1) such Sale-Leaseback Transaction occurs within one year from the date of completion of the acquisition of the Principal Property subject thereto or the date of the completion of construction, development or substantial repair or improvement, or commencement of full operations on such Principal Property, whichever is later;

(2) the Sale-Leaseback Transaction involves a lease for a period, including renewals, of not more than three years;

(3) the Guarantor or such Subsidiary would be entitled to incur debt secured by a lien on the Principal Property subject thereto in a principal amount equal to or exceeding the Attributable Indebtedness from such Sale-Leaseback Transaction without equally and ratably securing the debt securities; or

(4) the Guarantor or such Subsidiary, within a one-year period after such Sale-Leaseback Transaction, applies or causes to be applied an amount not less than the Attributable Indebtedness from such Sale-Leaseback Transaction to (a) the prepayment, repayment, redemption, reduction or retirement of any debt of the Guarantor or any Subsidiary that is not subordinated to the debt securities, or (b) the expenditure or expenditures for Principal Property used or to be used in the ordinary course of business of the Guarantor or its Subsidiaries.

“Attributable Indebtedness,” when used with respect to any Sale-Leaseback Transaction, means, as at the time of determination, the present value (discounted at the rate set forth or implicit in the terms of the lease included in such transaction) of the total obligations of the lessee for rental payments (other than amounts required to be paid on account of property taxes, maintenance, repairs, insurance, assessments, utilities, operating and labor costs and other items that do not constitute payments for property rights) during the remaining term of the lease included in such Sale-Leaseback Transaction (including any period for which such lease has been extended). In the case of any lease that is terminable by the lessee upon the payment of a penalty or other termination payment, such amount shall be the lesser of the amount determined assuming termination upon the first date such lease may be terminated (in which case the amount shall also include the amount of the penalty or termination payment, but no rent shall be considered as required to be paid under such lease subsequent to the first date upon which it may be so terminated) or the amount determined assuming no such termination.

Notwithstanding the preceding, under the Indenture the Guarantor may, and may permit any Subsidiary to, effect any Sale-Leaseback Transaction that is not excepted by clauses (1) through (4), inclusive, of the first paragraph under “— Restrictions on Sale-Leasebacks,” provided that the Attributable Indebtedness from such Sale-Leaseback Transaction, together with the aggregate principal amount of all other such Attributable Indebtedness deemed to be outstanding in respect of all Sale-Leaseback Transactions and all outstanding debt (other than the debt securities) secured by liens (other than Permitted Liens) upon Principal Properties or upon capital stock of any Restricted Subsidiary, do not exceed 10% of Consolidated Net Tangible Assets.

Merger, Consolidation or Sale of Assets. The Indenture provides that each of the Guarantor and the Issuer may, without the consent of the holders of any of the debt securities, consolidate with or sell, lease, convey all or substantially all of its assets to, or merge with or into, any partnership, limited liability company or corporation if:

(1) the entity surviving any such consolidation or merger or to which such assets shall have been transferred (the “successor”) is either the Guarantor or the Issuer, as applicable, or the successor is a domestic partnership, limited liability company or corporation and expressly assumes all the Guarantor’s or the Issuer’s, as the case may be, obligations and liabilities under the Indenture and the debt securities (in the case of the Issuer) and the Guarantee (in the case of the Guarantor);

(2) immediately after giving effect to the transaction no Default or Event of Default has occurred and is continuing; and

(3) the Issuer and the Guarantor have delivered to the Trustee an officers’ certificate and an opinion of counsel, each stating that such consolidation, merger or transfer complies with the Indenture.

The successor will be substituted for the Guarantor or the Issuer, as the case may be, in the Indenture with the same effect as if it had been an original party to the Indenture. Thereafter, the successor may exercise the rights and powers of the Guarantor or the Issuer, as the case may be, under the Indenture, in its name or in its own name. If the Guarantor or the Issuer sells or transfers all or substantially all of its assets, it will be released from all liabilities and obligations under the Indenture and under the debt securities (in the case of the Issuer) and the Guarantee (in the case of the Guarantor) except that no such release will occur in the case of a lease of all or substantially all of its assets.

Events of Default

Each of the following will be an Event of Default under the Indenture with respect to a series of debt securities:

(1) default in any payment of interest on any debt securities of that series when due, continued for 30 days;

(2) default in the payment of principal of or premium, if any, on any debt securities of that series when due at its stated maturity, upon optional redemption, upon declaration or otherwise;

(3) failure by the Guarantor or the Issuer to comply for 60 days after notice with its other agreements contained in the Indenture;

(4) certain events of bankruptcy, insolvency or reorganization of the Issuer or the Guarantor (the “bankruptcy provisions”); or

(5) the Guarantee ceases to be in full force and effect or is declared null and void in a judicial proceeding or the Guarantor denies or disaffirms its obligations under the Indenture or the Guarantee.

However, a default under clause (3) of this paragraph will not constitute an Event of Default until the Trustee or the holders of at least 25% in principal amount of the outstanding debt securities of that series notify the Issuer and the Guarantor of the default such default is not cured within the time specified in clause (3) of this paragraph after receipt of such notice.

An Event of Default for a particular series of debt securities will not necessarily constitute an Event of Default for any other series of debt securities that may be issued under the Indenture. If an Event of Default (other than an Event of Default described in clause (4) above) occurs and is continuing, the Trustee by notice to the Issuer, or the holders of at least 25% in principal amount of the outstanding debt securities of that series by notice to the Issuer and the Trustee, may, and the Trustee at the request of such holders shall, declare the principal of, premium, if any, and accrued and unpaid interest, if any, on all the debt securities of that series to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid interest will be due and payable immediately. If an Event of Default described in clause (4) above occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the debt securities will become and be immediately due and payable without any declaration or other act on the part of the Trustee or any holders. However, the effect of such provision may be limited by applicable law. The holders of a majority in principal amount of the outstanding debt securities of a series may rescind any such acceleration with respect to the debt securities of that series and its consequences if rescission would not conflict with any judgment or decree of a court of competent jurisdiction and all existing Events of Default with respect to that series, other than the nonpayment of the principal of, premium, if any, and interest on the debt securities of that series that have become due solely by such declaration of acceleration, have been cured or waived.

Subject to the provisions of the Indenture relating to the duties of the Trustee, if an Event of Default with respect to a series of debt securities occurs and is continuing, the Trustee will be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any of the holders of debt securities of that series, unless such holders have offered to the Trustee reasonable indemnity or security against any loss, liability or expense. Except to enforce the right to receive payment of principal, premium, if any, or interest when due, no holder of debt securities of any series may pursue any remedy with respect to the Indenture or the debt securities of that series unless:

(1) such holder has previously given the Trustee notice that an Event of Default with respect to the debt securities of that series is continuing;

(2) holders of at least 25% in principal amount of the outstanding debt securities of that series have requested the Trustee to pursue the remedy;

(3) such holders have offered the Trustee reasonable security or indemnity against any loss, liability or expense;

(4) the Trustee has not complied with such request within 60 days after the receipt of the request and the offer of security or indemnity; and

(5) the holders of a majority in principal amount of the outstanding debt securities of that series have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period.

Subject to certain restrictions, the holders of a majority in principal amount of the outstanding debt securities of each series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee with respect to that series of debt securities. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other holder of debt securities of that series or that would involve the Trustee in personal liability.

The Indenture provides that if a Default (that is, an event that is, or after notice or the passage of time would be, an Event of Default) with respect to the debt securities of a particular series occurs and is continuing and is known to the Trustee, the Trustee must mail to each holder of debt securities of that series notice of the Default within 90 days after it occurs. Except in the case of a Default in the payment of principal of, premium, if any, or interest on the debt securities of that series, the Trustee may withhold notice, but only if and so long as the Trustee in good faith determines that withholding notice is in the interests of the holders of debt securities of that

series. In addition, the Issuer is required to deliver to the Trustee, within 120 days after the end of each fiscal year, an officers’ certificate as to compliance with all covenants in the Indenture and indicating whether the signers thereof know of any Default or Event of Default that occurred during the previous year. The Issuer also is required to deliver to the Trustee, within 30 days after the occurrence thereof, an officers’ certificate specifying any Default or Event of Default, its status and what action the Issuer is taking or proposes to take in respect thereof.

Amendments and Waivers

Amendments of the Indenture may be made by the Issuer, the Guarantor and the Trustee with the consent of the holders of a majority in principal amount of all debt securities of each series affected thereby then outstanding under the Indenture (including consents obtained in connection with a tender offer or exchange offer for the debt securities). However, without the consent of each holder of outstanding debt securities affected thereby, no amendment may, among other things:

(1) reduce the percentage in principal amount of debt securities whose holders must consent to an amendment;

(2) reduce the stated rate of or extend the stated time for payment of interest on any debt securities;

(3) reduce the principal of or extend the stated maturity of any debt securities;

(4) reduce the premium payable upon the redemption of any debt securities or change the time at which any debt securities may be redeemed;

(5) make any debt securities payable in money other than that stated in the debt securities;

(6) impair the right of any holder to receive payment of, premium, if any, principal of and interest on such holder’s debt securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such holder’s debt securities;

(7) make any change in the amendment provisions which require each holder’s consent or in the waiver provisions;

(8) release any security that may have been granted in respect of the debt securities; or

(9) release the Guarantor or modify the Guarantee in any manner adverse to the holders.

The holders of a majority in aggregate principal amount of the outstanding debt securities of each series affected thereby, may waive compliance by the Issuer and the Guarantor with certain restrictive covenants on behalf of all holders of debt securities of such series, including those described under “— Certain Covenants — Limitations on Liens” and “— Certain Covenants — Restriction on Sale-Leasebacks.” The holders of a majority in principal amount of the outstanding debt securities of each series affected thereby, on behalf of all such holders, may waive any past Default or Event of Default with respect to that series (including any such waiver obtained in connection with a tender offer or exchange offer for the debt securities), except a Default or Event of Default in the payment of principal, premium or interest or in respect of a provision that under the Indenture that cannot be amended without the consent of all holders of the series of debt securities that is affected.

Without the consent of any holder, the Issuer, the Guarantor and the Trustee may amend the Indenture to:

(1) cure any ambiguity, omission, defect or inconsistency;

(2) provide for the assumption by a successor of the obligations of the Guarantor or the Issuer under the Indenture;

(3) provide for uncertificated debt securities in addition to or in place of certificated debt securities (provided that the uncertificated debt securities are issued in registered form for purposes of Section 163(f) of the Code, or in a manner such that the uncertificated debt securities are described in Section 163(f)(2)(B) of the Code);

(4) add or release guarantees by any Subsidiary with respect to the debt securities, in either case as provided in the Indenture;

(5) secure the debt securities or a guarantee;

(6) add to the covenants of the Guarantor or the Issuer for the benefit of the holders or surrender any right or power conferred upon the Guarantor or the Issuer;

(7) make any change that does not adversely affect the rights of any holder;

(8) comply with any requirement of the Commission in connection with the qualification of the Indenture under the Trust Indenture Act; and

(9) issue any other series of debt securities under the Indenture.

The consent of the holders is not necessary under the Indenture to approve the particular form of any proposed amendment. It is sufficient if such consent approves the substance of the proposed amendment. After an amendment requiring consent of the holders becomes effective, the Issuer is required to mail to the holders of an affected series a notice briefly describing such amendment. However, the failure to give such notice to all such holders, or any defect therein, will not impair or affect the validity of the amendment.

Defeasance and Discharge

The Issuer at any time may terminate all its obligations under the Indenture as they relate to a series of debt securities (“legal defeasance”), except for certain obligations, including those respecting the defeasance trust and obligations to register the transfer or exchange of the debt securities of that series, to replace mutilated, destroyed, lost or stolen debt securities of that series and to maintain a registrar and paying agent in respect of such debt securities.

The Issuer at any time may terminate its obligations under covenants described under “— Certain Covenants” (other than “Merger, Consolidation or Sale of Assets”) and the bankruptcy provisions with respect to the Guarantor, and the Guarantee provision, described under “— Events of Default” above with respect to a series of debt securities (“covenant defeasance”).

The Issuer may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If the Issuer exercises its legal defeasance option, payment of the defeased series of debt securities may not be accelerated because of an Event of Default with respect thereto. If the Issuer exercises its covenant defeasance option, payment of the affected series of debt securities may not be accelerated because of an Event of Default specified in clause (3), (4), (with respect only to the Guarantor) or (5) under “— Events of Default” above. If the Issuer exercises either its legal defeasance option or its covenant defeasance option, each guarantee will terminate with respect to the debt securities of the defeased series and any security that may have been granted with respect to such debt securities will be released.

In order to exercise either defeasance option, the Issuer must irrevocably deposit in trust (the “defeasance trust”) with the Trustee money, U.S. Government Obligations (as defined in the Indenture) or a combination thereof for the payment of principal, premium, if any, and interest on the relevant series of debt securities to redemption or maturity, as the case may be, and must comply with certain other conditions, including delivery to the Trustee of an opinion of counsel (subject to customary exceptions and exclusions) to the effect that holders of that series of debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and defeasance and will be subject to federal income tax on the same amounts and in the same manner and at the same times as would have been the case if such defeasance had not occurred. In the case of legal defeasance only, such opinion of counsel must be based on a ruling of the Internal Revenue Service (“IRS”) or other change in applicable federal income tax law.

In the event of any legal defeasance, holders of the debt securities of the relevant series would be entitled to look only to the trust fund for payment of principal of and any premium and interest on their debt securities until maturity.

Although the amount of money and U.S. Government Obligations on deposit with the Trustee would be intended to be sufficient to pay amounts due on the debt securities of a defeased series at the time of their stated maturity, if the Issuer exercises its covenant defeasance option for the debt securities of any series and the debt securities are declared due and payable because of the occurrence of an Event of Default, such amount may not be sufficient to pay amounts due on the debt securities of that series at the time of the acceleration resulting from such Event of Default. The Issuer would remain liable for such payments, however.

In addition, the Issuer may discharge all its obligations under the Indenture with respect to debt securities of any series, other than its obligation to register the transfer of and exchange notes of that series, provided that it either:

•

delivers all outstanding debt securities of that series to the Trustee for cancellation; or

•

all such debt securities not so delivered for cancellation have either become due and payable or will become due and payable at their stated maturity within one year or are called for redemption within one year, and in the case of this bullet point the Issuer has deposited with the Trustee in trust an amount of cash sufficient to pay the entire indebtedness of such debt securities, including interest to the stated maturity or applicable redemption date.

Subordination

Debt securities of a series may be subordinated to our Senior Indebtedness, which we define generally to include all notes or other evidences of indebtedness for money borrowed by the Issuer, including guarantees, that are not expressly subordinate or junior in right of payment to any other indebtedness of the Issuer. Subordinated debt securities and the Guarantor’s guarantee thereof will be subordinate in right of payment, to the extent and in the manner set forth in the Indenture and the prospectus supplement relating to such series, to the prior payment of all indebtedness of the Issuer and Guarantor that is designated as “Senior Indebtedness” with respect to the series.

The holders of Senior Indebtedness of the Issuer will receive payment in full of the Senior Indebtedness before holders of subordinated debt securities will receive any payment of principal, premium or interest with respect to the subordinated debt securities:

•

upon any payment of distribution of our assets of the Issuer to its creditors;

•

upon a total or partial liquidation or dissolution of the Issuer; or

•

in a bankruptcy, receivership or similar proceeding relating to the Issuer or its property.

Until the Senior Indebtedness is paid in full, any distribution to which holders of subordinated debt securities would otherwise be entitled will be made to the holders of Senior Indebtedness, except that such holders may receive units representing limited partner interests and any debt securities that are subordinated to Senior Indebtedness to at least the same extent as the subordinated debt securities.

If the Issuer does not pay any principal, premium or interest with respect to Senior Indebtedness within any applicable grace period (including at maturity), or any other default on Senior Indebtedness occurs and the maturity of the Senior Indebtedness is accelerated in accordance with its terms, the Issuer may not:

•

make any payments of principal, premium, if any, or interest with respect to subordinated debt securities;

•

make any deposit for the purpose of defeasance of the subordinated debt securities; or

•

repurchase, redeem or otherwise retire any subordinated debt securities, except that in the case of subordinated debt securities that provide for a mandatory sinking fund, we may deliver subordinated debt securities to the Trustee in satisfaction of our sinking fund obligation,

unless, in either case,

•

the default has been cured or waived and the declaration of acceleration has been rescinded;

•

the Senior Indebtedness has been paid in full in cash; or

•

the Issuer and the Trustee receive written notice approving the payment from the representatives of each issue of “Designated Senior Indebtedness.”

Generally, “Designated Senior Indebtedness” will include:

•

indebtedness for borrowed money under a bank credit agreement, called “Bank Indebtedness”; and

•

any specified issue of Senior Indebtedness of at least $100 million.

During the continuance of any default, other than a default described in the immediately preceding paragraph, that may cause the maturity of any Senior Indebtedness to be accelerated immediately without further notice, other than any notice required to effect such acceleration, or the expiration of any applicable grace periods, the Issuer may not pay the subordinated debt securities for a period called the “Payment Blockage Period.” A Payment Blockage Period will commence on the receipt by us and the Trustee of written notice of the default, called a “Blockage Notice,” from the representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period.

The Payment Blockage Period may be terminated before its expiration:

•

by written notice from the person or persons who gave the Blockage Notice;

•

by repayment in full in cash of the Senior Indebtedness with respect to which the Blockage Notice was given; or

•

if the default giving rise to the Payment Blockage Period is no longer continuing.

Unless the holders of Senior Indebtedness shall have accelerated the maturity of the Senior Indebtedness, we may resume payments on the subordinated debt securities after the expiration of the Payment Blockage Period.

Generally, not more than one Blockage Notice may be given in any period of 360 consecutive days unless the first Blockage Notice within the 360-day period is given by holders of Designated Senior Indebtedness, other than Bank Indebtedness, in which case the representative of the Bank Indebtedness may give another Blockage Notice within the period. The total number of days during which any one or more Payment Blockage Periods are in effect, however, may not exceed an aggregate of 179 days during any period of 360 consecutive days.

After all Senior Indebtedness is paid in full and until the subordinated debt securities are paid in full, holders of the subordinated debt securities shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness.

By reason of the subordination, in the event of insolvency, our creditors who are holders of Senior Indebtedness, as well as certain of our general creditors, may recover more, ratably, than the holders of the subordinated debt securities.

Form and Denomination

Unless otherwise indicated in a prospectus supplement, the debt securities of a series will be issued as Registered Securities in denominations of $1,000 and any integral multiple thereof.

Book-Entry System

Unless otherwise indicated in a prospectus supplement, we will issue the debt securities in the form of one or more global securities in fully registered form initially in the name of Cede & Co., as nominee of The Depository Trust Company (“DTC”), or such other name as may be requested by an authorized representative of DTC. Unless otherwise indicated in a prospectus supplement, the global securities will be deposited with the Trustee as custodian for DTC and may not be transferred except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or another nominee of DTC or by DTC or any nominee to a successor of DTC or a nominee of such successor.

DTC has advised us as follows:

•

DTC holds securities that its participants deposit with DTC and facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities, such as transfers and pledges, through electronic computerized book-entry transfers and pledges between direct participants’ accounts, thereby eliminating the need for physical movement of securities certificates.

•

Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations.

•

DTC is a wholly owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries.

•

Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly.

•

The rules applicable to DTC and its direct and indirect participants are on file with the Commission.

Purchases of debt securities under the DTC system must be made by or through direct participants, which will receive a credit for the debt securities on DTC’s records. The ownership interest of each actual purchaser of debt securities is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners of the debt securities will not receive written confirmation from DTC of their purchase, but beneficial owners are expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the debt securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the debt securities, except in the event that use of the book-entry system for the debt securities is discontinued.

To facilitate subsequent transfers, all debt securities deposited by direct participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of debt securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the debt securities; DTC’s records reflect only the identity of the direct participants to whose accounts such debt securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to direct participants, by, direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the global securities. Under its usual procedures, DTC mails an omnibus proxy to the issuer as soon as possible after the record date. The omnibus proxy assigns Cede & Co.’s consenting or voting rights to those direct participants to whose accounts the debt securities are credited on the record date (identified in the listing attached to the omnibus proxy).

All payments on the global securities will be made to Cede & Co., as holder of record, or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the Trustee on payment dates in accordance with their respective holdings shown on DTC’s records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in “street name,” and will be the responsibility of such participant and not of DTC, us or the Trustee, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of principal, premium, if any, and interest to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) shall be the responsibility of us or the Trustee. Disbursement of such payments to direct participants shall be the responsibility of DTC, and disbursement of such payments to the beneficial owners shall be the responsibility of direct and indirect participants.

DTC may discontinue providing its service as securities depositary with respect to the debt securities at any time by giving reasonable notice to us or the Trustee. In addition, we may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary). Under such circumstances, in the event that a successor securities depositary is not obtained, note certificates in fully registered form are required to be printed and delivered to beneficial owners of the global securities representing such debt securities.

Neither we nor the Trustee will have any responsibility or obligation to direct or indirect participants, or the persons for whom they act as nominees, with respect to the accuracy of the records of DTC, its nominee or any participant with respect to any ownership interest in the debt securities, or payments to, or the providing of notice to participants or beneficial owners.

So long as the debt securities are in DTC’s book-entry system, secondary market trading activity in the debt securities will settle in immediately available funds. All payments on the debt securities issued as global securities will be made by us in immediately available funds.

The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.

Limitations on Issuance of Bearer Securities

The debt securities of a series may be issued as Registered Securities (which will be registered as to principal and interest in the register maintained by the registrar for the debt securities) or Bearer Securities (which will be transferable only by delivery). If the debt securities are issuable as Bearer Securities, certain special limitations and conditions will apply.

In compliance with United States federal income tax laws and regulations, we and any underwriter, agent or dealer participating in an offering of Bearer Securities will agree that, in connection with the original issuance of the Bearer Securities and during the period ending 40 days after the issue date, they will not offer, sell or deliver any such Bearer Securities, directly or indirectly, to a United States Person (as defined below) or to any person within the United States, except to the extent permitted under United States Treasury regulations.

Bearer Securities will bear a legend to the following effect: “Any United States person who holds this obligation will be subject to limitations under the United States federal income tax laws, including the limitations provided in Sections 165(j) and 1287(a) of the Internal Revenue Code.” The sections referred to in the legend provide that, with certain exceptions, a United States taxpayer who holds Bearer Securities will not be allowed to deduct any loss with respect to, and will not be eligible for capital gain treatment with respect to any gain realized on the sale, exchange, redemption or other disposition of, the Bearer Securities.

For this purpose, “United States” includes the United States of America and its possessions, and “United States person” means a citizen or resident of the United States, a corporation, partnership or other entity created or organized in or under the laws of the United States, or an estate or trust the income of which is subject to United States federal income taxation regardless of its source.

Pending the availability of a definitive global security or individual Bearer Securities, as the case may be, debt securities that are issuable as Bearer Securities may initially be represented by a single temporary global security, without interest coupons, to be deposited with a common depositary for the Euroclear System as operated by Euroclear Bank S.A./N.V. (“Euroclear”) and Clearstream Banking S.A. (“Clearstream”, formerly Cedelbank), for credit to the accounts designated by or on behalf of the purchasers thereof. Following the availability of a definitive global security in bearer form, without coupons attached, or individual Bearer Securities and subject to any further limitations described in the applicable prospectus supplement, the temporary global security will be exchangeable for interests in the definitive global security or for the individual Bearer Securities, respectively, only upon receipt of a “Certificate of Non-U.S. Beneficial Ownership,” which is a certificate to the effect that a beneficial interest in a temporary global security is owned by a person that is not a United States Person or is owned by or through a financial institution in compliance with applicable United States Treasury regulations. No Bearer Security will be delivered in or to the United States. If so specified in the applicable prospectus supplement, interest on a temporary global security will be paid to each of Euroclear and Clearstream with respect to that portion of the temporary global security held for its account, but only upon receipt as of the relevant interest payment date of a Certificate of Non-U.S. Beneficial Ownership.

No Recourse Against General Partner

The Guarantor’s general partner and its directors, officers, employees and members, as such, shall have no liability for any obligations of the Issuer or the Guarantor under the debt securities, the Indenture or the guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each holder by accepting a note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the debt securities. Such waiver may not be effective to waive liabilities under the federal securities laws, and it is the view of the Commission that such a waiver is against public policy.

Concerning the Trustee

The Indenture contains certain limitations on the right of the Trustee, should it become our creditor, to obtain payment of claims in certain cases, or to realize for its own account on certain property received in respect of any such claim as security or otherwise. The Trustee is permitted to engage in certain other transactions. However, if it acquires any conflicting interest within the meaning of the Trust Indenture Act, it must eliminate the conflict or resign as Trustee.

The holders of a majority in principal amount of all outstanding debt securities (or if more than one series of debt securities under the Indenture is affected thereby, all series so affected, voting as a single class) will have the right to direct the time, method and place of conducting any proceeding for exercising any remedy or power available to the Trustee for the debt securities or all such series so affected.

If an Event of Default occurs and is not cured under the Indenture and is known to the Trustee, the Trustee shall exercise such of the rights and powers vested in it by the Indenture and use the same degree of care and skill

in its exercise as a prudent person would exercise or use under the circumstances in the conduct of his own affairs. Subject to such provisions, the Trustee will not be under any obligation to exercise any of its rights or powers under the Indenture at the request of any of the holders of debt securities unless they shall have offered to such Trustee reasonable security and indemnity.

Wells Fargo Bank, National Association is the Trustee under the Indenture and has been appointed by the Issuer as Registrar and Paying Agent with regard to the debt securities. Wells Fargo Bank, National Association is a lender under the Issuer’s credit facilities.
