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 August 11, 2025, there is more than an insubstantial risk that interest payable by the Partnership on the Notes is not deductible, or within 90 days would not be deductible, in whole or in part, by the Partnership for United States federal income tax purposes.

ARTICLE II

GENERAL TERMS OF THE NOTES

SECTION 2.1 Form.

The Notes and the Trustee’s certificates of authentication shall be substantially in the form of Exhibit A to this Ninth Supplemental Indenture, which is hereby incorporated into this Ninth Supplemental Indenture. The terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Ninth Supplemental Indenture and, to the extent applicable, the Partnership and the Trustee, by their execution and delivery of this Ninth Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby.

The Notes shall be issued upon original issuance in whole in the form of one or more Global Securities (the “Book-Entry Notes”). Each Book-Entry Note shall represent such of the outstanding Notes as shall be specified therein and shall provide that it shall represent the aggregate principal amount of outstanding Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions.

The Partnership initially appoints The Depository Trust Company to act as Depositary with respect to the Book-Entry Notes.

SECTION 2.2 Title, Amount and Payment of Principal and Interest.

(a) The Notes shall be entitled the “Series 2025B Junior Subordinated Notes due 2056.” The Trustee shall authenticate and deliver (i) the Notes for original issue on the date hereof (the “Original Notes”) in the aggregate principal amount of $800,000,000, and (ii) additional Notes for original issue from time to time after the date hereof in such principal amounts as may be specified in a Partnership Order, in each case, upon a Partnership Order for the authentication and delivery thereof and satisfaction of the other provisions of Section 2.04 of the Base Indenture. Such Partnership Order shall specify the amount of the Notes to be authenticated, the date on which the original issue of Notes is to be authenticated, and the name or names of the initial Holder or Holders. The aggregate principal amount of Notes that may be outstanding at any time may not exceed $800,000,000 plus such additional principal amounts as may be issued and authenticated pursuant to clause (ii) of this paragraph (except as provided in Section 2.09 of the Base Indenture). The Original Notes and any additional Notes issued and authenticated pursuant to clause (ii) of this paragraph shall constitute a single series of Debt Securities for all purposes under the Indenture.

(b) The Notes shall bear interest (i) from and including the Original Issue Date to, but excluding, the First Reset Date at the rate of 6.750% per annum and (ii) from and including the First Reset Date, during each Reset Period at a rate per annum equal to the Five-year U.S. Treasury Rate as of the most recent Reset Interest Determination Date plus a spread of 2.475 percentage points, to be reset on each Reset Date, and shall have a Stated Maturity of February 15, 2056 (the “Maturity Date”). Interest accumulating or payable on the Notes for any Interest Payment Period (or portion thereof) will be calculated on the basis of a 360-day year of twelve 30-day months. Interest on the Notes shall be payable semi-annually in arrears on each February 15 and August 15 (each, an “Interest Payment Date”) of each year to Holders of record at the close of business on the immediately preceding Regular Record Date, subject to Section 2.4 hereof. If an Interest Payment Date is not a Business Day, payment of interest will be made on the next succeeding Business Day, without any interest, additional interest, or other payment in lieu of interest or additional interest accumulating with respect to this delay. The Partnership will give written notice of the relevant Five-year U.S. Treasury Rate as soon as reasonably practicable following each Reset Interest Determination Date to the Trustee and Paying Agent.

5

(c) If the Partnership, in its sole discretion, determines that the Five-year U.S. Treasury Rate cannot be determined pursuant to the methods set forth herein, the Partnership may, in its sole discretion, designate an unaffiliated agent or advisor, which may include an unaffiliated underwriter for the offering of the Notes or any affiliate of any such underwriter, but shall not include the Trustee (the “Designee”), to determine whether there is an industry-accepted successor rate to the Five-year U.S. Treasury Rate. If the Designee determines that there is such an industry-accepted successor rate, then the Five-year U.S. Treasury Rate shall be such successor rate and, in that case, the Designee may adjust the spread and may determine and adjust the Business Day convention, the definition of a “Business Day” and the Reset Interest Determination Date to be used and any other relevant methodology for determining or otherwise calculating such successor rate, including any adjustment factor needed to make such successor rate comparable to the Five-year U.S. Treasury Rate in each case, in a manner that is consistent with industry-accepted practices for the use of such successor rate. If the Partnership, in its sole discretion, does not designate a Designee or if the Designee determines that there is no industry-accepted successor rate, then the Five-year U.S. Treasury Rate will be the same rate determined for the prior Reset Interest Determination Date or, if this sentence is applicable with respect to the first Reset Interest Determination Date, the applicable interest rate for the First Reset Period (as defined below) will be 6.750%.

(d) In no event shall the Trustee be responsible for determining whether there is an industry-accepted successor rate to the Five-year U.S. Treasury Rate or for making any adjustments to any spread thereon or the Business Day convention or interest determination dates with respect thereto or any other relevant methodology for calculating any such successor rate, including any adjustment factor needed to make such successor rate comparable to the Five-year U.S. Treasury Rate in each case, in a manner that is consistent with industry-accepted practices for the use of such successor rate. In connection with the foregoing, the Trustee shall be entitled to conclusively rely on any determination made by the Partnership or its Designee and will have no liability for such actions taken at the Partnership’s or Designee’s direction or otherwise in connection with respect to any such determination by the Partnership or its Designee.

(e) Payments of principal of, premium, if any, on, and interest due on the Notes representing Book-Entry Notes on any Interest Payment Date or on the Maturity Date will be made available to the Trustee by 10:00 a.m., New York City time, on such date, unless such date falls on a day that is not a Business Day, in which case (x) such payments will be made available to the Trustee by 10:00 a.m., New York City time, on the next Business Day, and (y) for so long as clause (x) is satisfied, no interest shall accrue on the amount of interest due on such Interest Payment Date for the period from and after such Interest Payment Date and the date of payment. As soon as possible thereafter, the Trustee will make such payments to the Depositary.

6

SECTION 2.3 Regular Record Date

With respect to each Interest Payment Date, the record date for the Notes shall be February 1 and August 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date (each, a “Regular Record Date”).

SECTION 2.4 Deferral of Interest.

(a) So long as no Event of Default with respect to the Notes has occurred and is continuing, the Partnership may, at its option, defer interest payments on the Notes, from time to time, for one or more deferral periods of up to 20 consecutive Interest Payment Periods (each such deferral period, commencing on the Interest Payment Date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the Maturity Date or end on a day other than the day immediately preceding an Interest Payment Date. During any Optional Deferral Period, interest on the Notes will continue to accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes). In addition, during any Optional Deferral Period, interest on the deferred interest (“compound interest”) will accrue at the then-applicable interest rate on the Notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the Notes), compounded semi-annually, to the extent permitted by applicable law.

(b) No interest will be due or payable on the Notes during an Optional Deferral Period, except upon a redemption of any Notes on any Redemption Date during such Optional Deferral Period (in which case, all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the Notes to be redeemed to, but excluding, such Redemption Date will be due and payable on such Redemption Date), or unless the principal of and interest on the Notes shall have been declared due and payable as the result of an Event of Default with respect to the Notes (in which case, all accrued and unpaid interest, including, to the extent permitted by applicable law, any compound interest, on the Notes, shall become due and payable). All references in the Notes and, insofar as relates to the Notes, the Indenture to “interest” on the Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any compound interest, unless otherwise expressly stated or the context otherwise requires.

(c) Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Partnership may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the Maturity Date. The Partnership may also elect, at its option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any compound interest), are paid, the Partnership may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Partnership may not begin a new Optional Deferral Period unless the Partnership has paid all accrued and unpaid interest on the Notes (including, without limitation and to the extent permitted by applicable law, any compound interest) from any previous Optional Deferral Periods.

7

(d) During any Optional Deferral Period, the Partnership (and its subsidiaries, as applicable) shall not do any of the following (subject to the exceptions set forth in clause (e) of this Section 2.4):

(1) declare or pay any dividends or distributions on any Capital Stock of the Partnership;

(2) redeem, purchase, acquire or make a liquidation payment with respect to any Capital Stock of the Partnership;

(3) pay any principal, interest or premium on, or repay, repurchase or redeem, any indebtedness of the Partnership that ranks equally with or junior to the Notes in right of payment; or

(4) make any payments with respect to any guarantees by the Partnership of any indebtedness if such guarantees rank equally with or junior to the Notes in right of payment.

(e) However, during an Optional Deferral Period, the Partnership may (i) declare and pay dividends or distributions payable solely in its common units (together with cash in lieu of any fractional unit) or options, warrants or rights to subscribe for or purchase units of its common units, (ii) declare and pay any dividend or distribution in connection with the implementation of a plan (a “Rights Plan”) providing for the issuance by the Partnership to all holders of its common units of rights entitling them to subscribe for or purchase its common units or any class or series of its preferred equity, which rights (1) are deemed to be transferred with such common units, (2) are not exercisable until the occurrence of a specified event or events and (3) are also issued in respect of future issuances of its common units, (iii) issue any of shares of its Capital Stock under any Rights Plan or redeem or repurchase any rights distributed pursuant to a Rights Plan, (iv) reclassify its Capital Stock or exchange or convert one class or series of its Capital Stock for another class or series of its Capital Stock, (v) purchase fractional interests in shares of its Capital Stock pursuant to the conversion or exchange provisions of such Capital Stock or the security being converted or exchanged, and (vi) purchase, acquire or withhold its common units related to the issuance of its common units or rights under any dividend reinvestment plan or related to any of its benefit plans for its directors, officers, employees, consultants or advisors, including any employment contract.

(f) The Partnership will give the Holders of the Notes and the Trustee written notice of its election of, or any shortening or extension of, an Optional Deferral Period at least 10 Business Days prior to the earlier of (i) the next succeeding Interest Payment Date or (ii) the date upon which the Partnership is required to give notice to any applicable self-regulatory organization or to Holders of the Notes of the next succeeding Interest Payment Date or the record date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any compound interest payable on the Interest Payment Date immediately following the last day of an Optional Deferral Period will be the Regular Record Date with respect to such Interest Payment Date.

8

SECTION 2.5 Interest Payments and Redemption.

Notwithstanding any provision of Article III of this Ninth Supplemental Indenture to the contrary, installments of interest on the Notes that are due and payable on any Interest Payment Date falling on or prior to a Redemption Date for the Notes will be payable on that Interest Payment Date to the registered Holders thereof as of the close of business on the relevant Regular Record Date according to the terms of the Notes and the Indenture, except that, if the Redemption Date for any Notes falls on any day during an Optional Deferral Period, accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on such Notes will be paid on such Redemption Date to the Persons entitled to receive the Redemption Price of such Notes. The Interest Payment Date falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

SECTION 2.6 Calculation Agent.

(a) Unless the Partnership has validly called all of the outstanding Notes for redemption during the First Reset Period, the Partnership will appoint a calculation agent (the “Calculation Agent”) for the Notes prior to the Reset Interest Determination Date immediately preceding the First Reset Date; provided that, if the Partnership has called all of the outstanding Notes for redemption on a Redemption Date occurring during the First Reset Period, but the Partnership does not redeem all of the outstanding Notes on such Redemption Date, the Partnership will appoint a Calculation Agent for the Notes prior to the Reset Interest Determination Date preceding the First Reset Date. The Partnership may terminate any such appointment and may appoint a successor Calculation Agent at any time and from time to time (so long as there shall always be a Calculation Agent in respect of the Notes when so required). The Partnership may appoint itself or an Affiliate of the Partnership as Calculation Agent.

(b) The applicable interest rate for each Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. Promptly upon such determination, the Calculation Agent will notify the Partnership of the interest rate for the Reset Period and the Partnership will promptly notify, or cause the Calculation Agent to promptly notify, the Trustee and Paying Agent for the Notes in writing of such interest rate, upon which the Trustee and Paying Agent will be permitted to conclusively rely. The Calculation Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Payment Period beginning on or after the First Reset Date, will be on file at the Partnership’s principal offices, will be made available to any Holder or beneficial owner of the Notes upon request and will be final and binding in the absence of manifest error.

SECTION 2.7 Transfer and Exchange.

The transfer and exchange of Book-Entry Notes or beneficial interests therein shall be effected through the Depositary, in accordance with Section 2.17 of the Base Indenture and Article II of this Ninth Supplemental Indenture (including the restrictions on transfer set forth therein and herein) and the rules and procedures of the Depositary therefor, which shall include restrictions on transfer comparable to those set forth therein and herein to the extent required by the Securities Act of 1933, as amended.

(3) if less than all the outstanding Debt Securities of any series and of a specified tenor consisting of more than a single Debt Security are to be redeemed, the identification (and, in the case of partial redemption of any such Debt Securities, the principal amounts) of the particular Debt Securities to be redeemed and, if less than all the outstanding Debt Securities of any series and of a specified tenor consisting of a single Debt Security are to be redeemed, the principal amount of the particular Debt Security to be redeemed;

(7) such other matters as the Partnership shall deem desirable or appropriate.

Unless otherwise specified with respect to any Debt Securities in accordance with Section 2.01 hereof, with respect to any redemption of Debt Securities at the election of the Partnership, unless, upon the giving of notice of such redemption, defeasance shall have been effected with respect to such Debt Securities pursuant to Article VIII hereof, such notice may state that such redemption shall be conditional upon the receipt by the Trustee or the Paying Agent(s) for such Debt Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and any premium and interest on such Debt Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Partnership shall not be required to redeem such Debt Securities.

SECTION 4.6 Acceleration.

Subject to the limitations set forth in the preamble to Article IV of this Ninth Supplemental Indenture, Section 6.02 of the Base Indenture is hereby amended and restated in its entirety to read as follows:

“If an Event of Default (other than an Event of Default set forth in clause (3) of the definition of Event of Default appearing in Section 6.01 hereof) with respect to the Notes occurs and is continuing, then either the Trustee or the Holders of not less than 33% in principal amount of the outstanding Notes may declare the principal amount of all the Notes and accrued and unpaid interest, if any, thereon to be due and payable immediately, by a notice in writing to the Partnership (and to the Trustee if given by Holders), and upon any such declaration, such principal amount of all outstanding Notes and accrued and unpaid interest, if any, thereon shall become immediately due and payable. If an Event of Default set forth in clauses (5) or (6) of the definition of Event of Default appearing in Section 6.01 hereof occurs and is continuing with respect to all series of Debt Securities (that are subordinated pursuant to Article V of the Ninth Supplemental Indenture or a similar subordination provision) at the time outstanding, then either the Trustee or the Holders of not less than 33% in principal amount of all such subordinated Debt Securities outstanding under this Indenture may declare the principal amount of all such outstanding subordinated Debt Securities, together with accrued and unpaid interest thereon, to be due and payable immediately, and upon any such declaration, such principal amount of all outstanding Notes and accrued and unpaid interest, if any, thereon shall become immediately due and payable.

14

The Holders of a majority in principal amount of the outstanding Notes may, by written notice to the Trustee, rescind any acceleration with respect to the Notes and annul 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 the Notes, other than the nonpayment of the principal of, premium, if any, and interest on the Notes that have become due solely by such acceleration, have been cured or waived.”

Subject to the limitations set forth in the preamble to Article IV of this Ninth Supplemental Indenture, Section 6.05 of the Base Indenture is hereby amended and restated in its entirety to read as follows:

“The Holders of a majority in principal amount of the outstanding Notes shall have the right to (i) direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or (ii) exercising any trust or power conferred on the Trustee, with respect to the Notes; provided that

(1) such direction shall not be in conflict with any law or with this Indenture,

(2) the Trustee may take any other action deemed proper by the Trustee which is consistent with such direction, and

(3) subject to the provisions of Section 7.01 hereof, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall, by a Responsible Officer or Officers of the Trustee, determine that the proceeding so directed would involve the Trustee in personal liability.

If an Event of Default is continuing with respect to all outstanding Debt Securities (that are subordinated pursuant to Article V of the Ninth Supplemental Indenture or a similar subordination provision), the Holders of a majority in principal amount of all such outstanding Debt Securities, considered as one class, shall have the right to make such direction, and not the Holders of such Debt Securities of any one series.”

SECTION 4.8 Notices.

Subject to the limitations set forth in the preamble to Article IV of this Ninth Supplemental Indenture, Section 11.02 of the Base Indenture is hereby amended to add the following sentence as the last paragraph of Section 11.02 of the Base Indenture:

SUBORDINATION

SECTION 5.1 Subordination

(a) any payment by, or distribution of the assets of, the Partnership upon its dissolution, winding-up, liquidation or reorganization, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings,

(b) a failure to pay any interest, principal or other monetary amounts due on any of the Senior Indebtedness when due and continuance of that default beyond any applicable grace period, or

(c) acceleration of the maturity of any Senior Indebtedness as a result of a default, the Holders of all Senior Indebtedness will be entitled to receive, in the case of clause (a) immediately above, payment of all amounts due or to become due on all Senior Indebtedness, or in the case of clauses (b) and (c) immediately above, payment of all amounts due on all Senior Indebtedness, before the Holders of the Notes are entitled to receive any payment. So long as any of the events in clauses (a), (b), or (c) immediately above has occurred and is continuing, any amounts payable or assets distributable on the Notes will instead be paid or distributed, as the case may be, directly to the Holders of Senior Indebtedness to the extent necessary to pay, in the case of clause (a) immediately above, all amounts due or to become due upon all such Senior Indebtedness, or, in the case of clauses (b) and (c) immediately above, all amounts due on all such Senior Indebtedness, and, if any such payment or distribution is received by the Trustee under the Indenture or the Holders of any of the Notes before all Senior Indebtedness due and to become due or due, as applicable, is paid, such payment or distribution must be paid over to the Holders of the unpaid Senior Indebtedness. Subject to paying the Senior Indebtedness due and to become due in the case of clause (a) immediately above or the Senior Indebtedness due in the case of clauses (b) and (c) immediately above, the Holders of the Notes will be subrogated to the rights of the Holders of the Senior Indebtedness to receive payments applicable to the Senior Indebtedness until the Notes are paid in full.

[REVERSE OF SECURITY]

ENERGY TRANSFER LP

Series 2025B Junior Subordinated Notes due 2056

This Security is one of a duly authorized issue of debentures, notes or other evidences of indebtedness of the Partnership (the “Debt Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to the Indenture, to which Indenture reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Partnership and the Holders of the Debt Securities. The Debt Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as provided in the Indenture. This Security is one of a series designated as the Series 2025B Junior Subordinated Notes due 2056 of the Partnership, in an initial aggregate principal amount of $800,000,000 (the “Securities”).

The Partnership promises to pay interest on the principal amount of this Security in accordance with the provisions hereof and of the Indenture. Interest on the Security shall be computed on the basis of a 360-day year of twelve 30-day months provided that for any partial 30-day month interest shall be computed on the basis of the actual number of days over a 30-day month. If an Interest Payment Date is not a Business Day (as defined in the Indenture), payment of interest will be made on the next succeeding Business Day, without any interest, additional interest, or other payment in lieu of interest or additional interest accumulating with respect to this delay. If any Interest Payment Date, Redemption Date or the Maturity Date of the Securities is not a Business Day at any place of payment, then payment of the principal, premium, if any, and interest may be made on the next Business Day at that place of payment. In that case, no interest will accrue on the amount payable for the period from and after the applicable Interest Payment Date, Redemption Date or Maturity Date, as the case may be. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security is registered at the close of business on the Regular Record Date for such interest, which shall be February 1 or August 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for (such interest, the “Default Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security is registered at the close of business on a special record date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such special record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

So long as no Event of Default with respect to the Securities of this series has occurred and is continuing, the Partnership may, at its option, defer interest payments on the Securities of this series, from time to time, as set forth in Section 2.4 of the Ninth Supplemental Indenture.

A-4

Payment of the principal of (and premium, if any) and any such interest on this Security will be made at the office or agency of the Partnership maintained for that purpose, in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however, that at the option of the Partnership payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the register of the Debt Securities (as set forth in Section 2.05 of the Base Indenture) or by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto.

Initially, U.S. Bank Trust Company, National Association will act as Paying Agent and Registrar. The Partnership may change any Paying Agent or Registrar at any time upon notice to the Trustee and the Holders. The Partnership may act as Paying Agent.

This Security is one of a duly authorized issue of Debt Securities of the Partnership issued and to be issued in one or more series under the Indenture.

Capitalized terms herein are used as defined in the Indenture unless otherwise defined herein. The terms of the Securities include those stated in the Base Indenture, those made part of the Indenture by reference to the TIA, as in effect on the date of the Base Indenture, and those terms stated in the Ninth Supplemental Indenture. The Securities are subject to all such terms, and Holders of Securities are referred to the Base Indenture, the Ninth Supplemental Indenture and the TIA for a statement of them. The Securities of this series are general unsecured obligations of the Partnership limited to an initial aggregate principal amount of $800,000,000; provided, however, that the authorized aggregate principal amount of such series may be increased from time to time as provided in the Ninth Supplemental Indenture.

(a) The Partnership may at its option redeem the Securities, in whole or from time to time in part, (i) on any day in the period commencing on the date falling 90 days prior to the First Reset Date and ending on (and including) the First Reset Date and (ii) after the First Reset Date, on any applicable Interest Payment Date at a Redemption Price in cash equal to 100% of the principal amount of the Securities to be redeemed, plus, subject to Section 2.5 of the Ninth Supplemental Indenture, accrued and unpaid interest on the Securities to be redeemed to, but excluding, the Redemption Date.

(b) The Partnership may at its option redeem the Securities, in whole but not in part, at any time within 120 days after a Tax Event at a Redemption Price in cash equal to 100% of the principal amount of the Securities, plus, subject to Section 2.5 of the Ninth Supplemental Indenture, accrued and unpaid interest on the Securities to, but excluding, the Redemption Date.

A-5

(c) The Partnership may at its option redeem the Securities, in whole but not in part, at any time during the continuance of and, in any event, within 120 days after the occurrence of, a Rating Agency Event at a Redemption Price in cash equal to 102% of the principal amount of the Securities, plus, subject to Section 2.5 of the Ninth Supplemental Indenture, accrued and unpaid interest on the Securities to, but excluding, the Redemption Date.

The Partnership is not required to make any mandatory redemption, mandatory repurchase or sinking fund payments with respect to the Securities or to repurchase the Securities at the option of Holders.

Securities in denominations larger than $2,000 in principal amount may be redeemed in part but only in integral multiples of $1,000.

The Securities of this series are issuable only in registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Partnership may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the register of the Debt Securities (as set forth in Section 2.05 of the Base Indenture), upon surrender of this Security for registration of transfer at the office or agency of the Partnership in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Partnership and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The registered Holder of a Security may be treated as the owner of it for all purposes.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Partnership and the rights of the Holders of the securities of all series affected under the Indenture at any time by the Partnership and the Trustee with the consent of the Holders of a majority in principal amount of the securities of all series at the time outstanding affected thereby (voting as one class). The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the securities

A-6

of all series at the time outstanding with respect to which a default under the Indenture shall have occurred and be continuing (voting as one class), on behalf of the Holders of the securities of all such series, to waive, with certain exceptions, such past default with respect to all such series and its consequences. The Indenture also permits the Holders of not less than a majority in principal amount of the securities of each series at the time outstanding, on behalf of the Holders of all securities of such series, to waive compliance by the Partnership with certain provisions of the Indenture. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 33% in principal amount of the Securities of this series at the time outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case, upon compliance with certain conditions set forth in the Indenture.

The Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Partnership or its Affiliates, and may otherwise deal with the Partnership or its Affiliates as if it were not the Trustee.

This Security shall not be valid until the Trustee signs the certificate of authentication hereon.

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Partnership has caused CUSIP numbers to be printed on the Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such number as printed on the Securities and reliance may be placed only on the other identification numbers printed hereon.

In the case of a redemption of Securities, notice of redemption will be in writing and mailed first-class postage-prepaid or otherwise delivered not less than 10 days nor more than 60 days prior to the Redemption Date to each Holder of the Securities to be redeemed at the Holder’s registered address; provided, however, that such notice need not state the dollar amount of the Redemption Price if such dollar amount has not been determined as of the date such notice is being given to the Holders of the Securities being redeemed. If money sufficient to pay the Redemption Price of all the Securities (or portions thereof) to be redeemed on the Redemption Date is deposited with the Paying Agent or the Trustee on or prior to the Redemption Date, from and after such Redemption Date such Securities or portions thereof shall cease to bear interest.

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

The Redemption Price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Partnership, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.

No director, officer, employee, limited partner or member, as such, of the Partnership or the General Partner shall have any personal liability in respect of the obligations of the Partnership under the Securities or the Indenture by reason of his, her or its status. Each Holder, by accepting the Securities, waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Securities.
