(a) The Partnership shall maintain for each Partner (or a beneficial owner of Partnership Interests held by a nominee in any case in which the nominee has furnished the identity of such owner to the Partnership in accordance with Section 6031(c) of the Code or any other method acceptable to the General Partner) owning a Partnership Interest a separate Capital Account with respect to such Partnership Interest in accordance with the rules of Treasury Regulation Section 1.704-1(b)(2)(iv). Such Capital Account shall be increased by (i) the amount of all Capital Contributions made to the Partnership with respect to such Partnership Interest and (ii) all items of Partnership income and gain (including, without limitation, income and gain exempt from tax) computed in accordance with Section 5.6(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1, and decreased by (x) the amount of cash or Net Agreed Value of all actual and deemed distributions of cash or property made with respect to such Partnership Interest (provided that the Capital Account of a Series A Holder, a Series B Holder, a Series C Holder, a Series D Holder, a Series E Holder, a Series F Holder or a Series G Holder shall not be reduced by any Series A Distributions, Series B Distributions, Series C Distributions, Series D Distributions, Series E Distributions, Series F Distributions or Series G Distributions it receives) and (y) all items of Partnership deduction and loss computed in accordance with Section 5.6(b) and allocated with respect to such Partnership Interest pursuant to Section 6.1. The Capital Account balance with respect to each Common Unit as of the Effective Date was the Closing Price of the Common Units on the Effective Date.

The initial Capital Account Balance in respect of each Class B Unit on the date hereof is the Class B Unit Price on such date.

(c) Article V of the Partnership Agreement is hereby amended by deleting Section 5.13 in its entirety and replacing with “[Reserved]” and adding a new Section 5.17, Section 5.18, Section 5.19, Section 5.20, Section 5.21, Section 5.22, Section 5.23 and Section 5.24 at the end thereof as follows:

“Section 5.17 Establishment of Series A Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “6.250% Series A Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units” (the “Series A Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.17. Each Series A Preferred Unit shall be identical in all respects to every other Series A Preferred Unit, except as to the respective dates from which the Series A Liquidation Preference shall increase or from which Series A Distributions may begin accruing, to the extent such dates may differ. The Series A Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series A Holder for conversion or, except as set forth in Section 5.17(b)(iv), redemption thereof at a particular date.

(b) Rights of Series A Preferred Units. The Series A Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series A Preferred Units.

(A) The authorized number of Series A Preferred Units shall be unlimited. Series A Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

17

(B) The Series A Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series A Holder shall be entitled to receive a definitive Certificate evidencing its Series A Preferred Units, unless (1) requested by a Series A Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series A Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series A Preferred Units, payments and communications made by the Partnership to Series A Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series A Preferred Unit shall be cumulative and shall accumulate at the applicable Series A Distribution Rate from and including February 16, 2021 (or, for any subsequently issued and newly Outstanding Series A Preferred Units, from and including the Series A Distribution Payment Date immediately preceding the issue date of such Series A Preferred Units) until such time as the Partnership pays the Series A Distribution or redeems such Series A Preferred Unit in accordance with Section 5.17(b)(iv), whether or not such Series A Distributions shall have been declared. Series A Holders shall be entitled to receive Series A Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series A Distribution Rate per Series A Preferred Unit when, as, and, if declared by the General Partner. Series A Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.17(b)(ii), shall be paid, in Arrears, on each Series A Distribution Payment Date. Series A Distributions shall accumulate in each Series A Distribution Period from and including the preceding Series A Distribution Payment Date (other than the initial Series A Distribution Period, which shall commence on and include February 16, 2021), to, but excluding, the next Series A Distribution Payment Date for such Series A Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series A Distributions at the Series A Distribution Rate. If any Series A Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series A Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. During the Series A Fixed Rate Period, Series A Distributions shall be payable based on a 360-day year consisting of twelve 30 day months. During the Series A Floating Rate Period, Series A Distributions shall be computed by multiplying the Series A Distribution Rate by a fraction, the numerator of which will be the actual number of days elapsed during that Series A Distribution Period (determined by including the first day of such Series A Distribution Period and excluding the last day, which is the Series A Distribution Payment Date), and the denominator of which will be 360, and by multiplying the result by the aggregate Series A Liquidation Preference of all Outstanding Series A Preferred Units. All Series A Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.17(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series A Distribution Period shall be for the account of the holders of Series A Preferred Units as of the applicable Series A Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series A Distribution Payment Date, the Partnership shall pay those Series A Distributions, if any, that shall have been declared by the General Partner to Series A Holders on the Record Date for the applicable Series A Distribution. The Record Date (the “Series A Distribution Record Date”) for the payment of any Series A Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series A Distribution Payment Date, except that in the case of payments of

18

Series A Distributions in Arrears, the Series A Distribution Record Date with respect to a Series A Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.17. So long as any Series A Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series A Junior Securities (other than a distribution payable solely in Series A Junior Securities) unless full cumulative Series A Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series A Preferred Units (and distributions on any other Series A Parity Securities) through the most recent respective Series A Distribution Payment Date (and distribution payment date with respect to such Series A Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.17(b)(ii)(B), if a distribution period with respect to a class of Series A Junior Securities or Series A Parity Securities is shorter than the Series A Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series A Junior Securities or Series A Parity Securities, so long as, at the time of declaration of such distribution, (1) there are no Series A Distributions in Arrears, and (2) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series A Preferred Units on the next successive Series A Distribution Payment Date. Accumulated Series A Distributions in Arrears for any past Series A Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series A Distribution Payment Date, to Series A Holders on the Record Date for such payment, which may not be less than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Series A Distributions in Arrears on all Outstanding Series A Preferred Units and all accumulated distributions in arrears on any Series A Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series A Preferred Units and accumulated distributions in arrears on any such Series A Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series A Preferred Units and any other Series A Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series A Preferred Units and any such other Series A Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series A Preferred Units and such other Series A Parity Securities at such time. Subject to Section 12.4 and Section 5.17(b)(v), Series A Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series A Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series A Distributions as described in Section 5.17(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series A Preferred Units. So long as the Series A Preferred Units are held of record by the Depositary or its nominee, declared Series A Distributions shall be paid to the Depositary in same-day funds on each Series A Distribution Payment Date or other distribution payment date in the case of payments for Series A Distributions in Arrears.

(C) The Series A Distribution Rate for each Series A Distribution Period in the Series A Floating Rate Period will be determined by the Calculation Agent using Three-Month LIBOR as in effect on the Distribution Determination Date for such Series A Distribution Period. The Calculation Agent then will add the spread of 4.028% per annum to Three-Month LIBOR as determined on the applicable Distribution Determination Date.

Notwithstanding the foregoing:

(A) If the Calculation Agent determines on the relevant Distribution Determination Date that the LIBOR base rate has been discontinued, then the Calculation Agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the LIBOR base rate, provided that if the Calculation Agent determines there is an industry-accepted

19

substitute or successor base rate, then the Calculation Agent shall use such substitute or successor base rate; and

(B) If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine what business day convention to use, the definition of business day, the Distribution Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate.

(C) Unless otherwise determined by the General Partner, Series A Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series A Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series A Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.17(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series A Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series A Preferred Units; provided, however, that (i) subject to Section 5.17(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.17(b)(iii)(B) and (ii) for purposes of this Section 5.17(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series A Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series A Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series A Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series A Preferred Units, voting as a class together with holders of any other Series A Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series A Parity Securities (including any additional Series A Preferred Units) if the cumulative distributions payable on Outstanding Series A Preferred Units (or any Series A Parity Securities, if the holders of such Series A Parity Securities vote as a class together with the Series A Holders pursuant to this Section 5.17(b)(iii)(C)) are in Arrears or (y) create or issue any Series A Senior Securities.

(D) For any matter described in this Section 5.17(b)(iii) in which the Series A Holders are entitled to vote as a class (whether separately or together with the holders of any Series A Parity Securities), such Series A Holders shall be entitled to one vote per Series A Preferred Unit. Any Series A Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Section 5.17(b)(iii)(B) and 5.17(b)(iii)(C), no vote of the Series A Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series A Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series A Rating Event.

(A) The Partnership shall have the right (1) at any time, and from time to time, on or after February 15, 2023 or (2) at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series A Rating Event, in each

20

case, to redeem the Series A Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (2) of this Section 5.17(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series A Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series A Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (1) of this Section 5.17(b)(iv)(A)), or 102% (in the case of a redemption described in clause (2) of this Section 5.17(b)(iv)(A)), of the Series A Liquidation Preference for such Series A Preferred Unit on such Series A Redemption Date plus an amount equal to all unpaid Series A Distributions thereon from the date of issuance to, but excluding, the Series A Redemption Date (whether or not such distributions shall have been declared) (the “Series A Redemption Price”). So long as the Series A Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series A Redemption Price shall be paid by the Paying Agent to the Depositary on the Series A Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 15 days and not more than 60 days before the scheduled Series A Redemption Date to the Series A Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series A Preferred Units to be redeemed as such Series A Holders’ names appear on the books of the Transfer Agent and at the address of such Series A Holders shown therein. Such notice (the “Series A Redemption Notice”) shall state, as applicable: (1) the Series A Redemption Date, (2) the number of Series A Preferred Units to be redeemed and, if less than all Outstanding Series A Preferred Units are to be redeemed, the number (and in the case of Series A Preferred Units in certificated form, the identification) of Series A Preferred Units to be redeemed from such Series A Holder, (3) the Series A Redemption Price, (4) the place where any Series A Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series A Redemption Price therefor (which shall occur automatically if the Certificate representing such Series A Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series A Preferred Units to be redeemed shall cease to accumulate from and after such Series A Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series A Preferred Units, the number of Series A Preferred Units to be redeemed shall be determined by the General Partner, and such Series A Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series A Preferred Units. The aggregate Series A Redemption Price for any such partial redemption of the Outstanding Series A Preferred Units shall be allocated correspondingly among the redeemed Series A Preferred Units. The Series A Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.17.

(D) If the Partnership gives or causes to be given a Series A Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series A Preferred Units as to which such Series A Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series A Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series A Redemption Price to each Series A Holder whose Series A Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series A Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series A Redemption Notice. If a Series A Redemption Notice shall have been given, from and after the Series A Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series A Redemption Notice, all Series A Distributions on such Series A Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series A Preferred Units as Limited

21

Partners with respect to such Series A Preferred Units to be redeemed shall cease, except the right to receive the Series A Redemption Price, and such Series A Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series A Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series A Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series A Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series A Holders entitled to such redemption or other payment shall have recourse only to the Partnership.

Notwithstanding any Series A Redemption Notice, there shall be no redemption of any Series A Preferred Units called for redemption until funds sufficient to pay the full Series A Redemption Price of such Series A Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series A Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series A Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series A Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series A Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series A Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.17, in the event that full cumulative distributions on the Series A Preferred Units and any Series A Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series A Preferred Units or Series A Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series A Holders and holders of any Series A Parity Securities. Subject to Section 4.9, so long as any Series A Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series A Junior Securities unless full cumulative distributions on the Series A Preferred Units and any Series A Parity Securities for all prior and the then-ending Series A Distribution Periods, with respect to the Series A Preferred Units, and all prior and then ending distribution periods, with respect to any such Series A Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights. In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series A Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series A Senior Securities or Series A Parity Securities), (A) first, any accumulated and unpaid distributions on the Series A Preferred Units (regardless of whether previously declared) and (B) then, any positive value in each such holder’s Capital Account in respect of such Series A Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series A Preferred Units is less than the aggregate Series A Base Liquidation Preference of such Series A Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series A Parity Securities upon which like allocation and distribution rights have been conferred), items of gross

22

income and gain shall be allocated to all Unitholders then holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series A Preferred Unit is equal to the Series A Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series A Parity Securities (including pursuant to Sections 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series A Preferred Units and such Series A Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series A Preferred Unit and such Series A Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series A Preferred Units is less than the aggregate Series A Base Liquidation Preference of such Series A Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series A Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series A Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series A Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series A Parity Securities (including pursuant to Sections 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series A Preferred Units and such Series A Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series A Preferred Unit and such Series A Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series A Preferred Units, and any Series A Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series A Preferred Units shall become entitled to receive any distributions in respect of the Series A Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series A Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series A Senior Securities or Series A Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series A Preferred Units.

(vi) Rank. The Series A Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series A Junior Securities;

(B) on a parity with any Series A Parity Securities;

(C) junior to any Series A Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund. The Series A Preferred Units shall not have the benefit of any sinking fund.

23

(viii) Record Holders. To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series A Holder as the true, lawful, and absolute owner of the applicable Series A Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series A Preferred Units may be listed or admitted to trading, if any.

(ix) Other Rights; Fiduciary Duties. The Series A Preferred Units and the Series A Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series A Holders, other than the implied contractual covenant of good faith and fair dealing.

“Section 5.18 Establishment of Series B Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “6.625% Series B Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units” (the “Series B Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.18. Each Series B Preferred Unit shall be identical in all respects to every other Series B Preferred Unit, except as to the respective dates from which the Series B Liquidation Preference shall increase or from which Series B Distributions may begin accruing, to the extent such dates may differ. The Series B Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series B Holder for conversion or, except as set forth in Section 5.18(b)(iv), redemption thereof at a particular date.

(b) Rights of Series B Preferred Units. The Series B Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series B Preferred Units.

(A) The authorized number of Series B Preferred Units shall be unlimited. Series B Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series B Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series B Holder shall be entitled to receive a definitive Certificate evidencing its Series B Preferred Units, unless (1) requested by a Series B Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series B Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series B Preferred Units, payments and communications made by the Partnership to Series B Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series B Preferred Unit shall be cumulative and shall accumulate at the applicable Series B Distribution Rate from and including February 16, 2021 (or, for any subsequently issued and newly Outstanding Series B Preferred Units, from and including the Series B Distribution Payment Date immediately preceding the issue date of such Series B Preferred Units) until such time as the Partnership pays the Series B Distribution or redeems such Series B Preferred Unit in accordance with Section 5.18(b)(iv), whether or not such Series B Distributions shall have been declared. Series B Holders shall be entitled to receive Series B

24

Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series B Distribution Rate per Series B Preferred Unit when, as, and, if declared by the General Partner. Series B Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.18(b)(ii), shall be paid, in Arrears, on each Series B Distribution Payment Date. Series B Distributions shall accumulate in each Series B Distribution Period from and including the preceding Series B Distribution Payment Date (other than the initial Series B Distribution Period, which shall commence on and include February 16, 2021), to, but excluding, the next Series B Distribution Payment Date for such Series B Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series B Distributions at the Series B Distribution Rate. If any Series B Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series B Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. During the Series B Fixed Rate Period, Series B Distributions shall be payable based on a 360-day year consisting of twelve 30 day months. During the Series B Floating Rate Period, Series B Distributions shall be computed by multiplying the Series B Distribution Rate by a fraction, the numerator of which will be the actual number of days elapsed during that Series B Distribution Period (determined by including the first day of such Series B Distribution Period and excluding the last day, which is the Series B Distribution Payment Date), and the denominator of which will be 360, and by multiplying the result by the aggregate Series B Liquidation Preference of all Outstanding Series B Preferred Units. All Series B Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.18(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series B Distribution Period shall be for the account of the holders of Series B Preferred Units as of the applicable Series B Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series B Distribution Payment Date, the Partnership shall pay those Series B Distributions, if any, that shall have been declared by the General Partner to Series B Holders on the Record Date for the applicable Series B Distribution. The Record Date (the “Series B Distribution Record Date”) for the payment of any Series B Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series B Distribution Payment Date, except that in the case of payments of Series B Distributions in Arrears, the Series B Distribution Record Date with respect to a Series B Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.18. So long as any Series B Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series B Junior Securities (other than a distribution payable solely in Series B Junior Securities) unless full cumulative Series B Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series B Preferred Units (and distributions on any other Series B Parity Securities) through the most recent respective Series B Distribution Payment Date (and distribution payment date with respect to such Series B Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.18(b)(ii)(B), if a distribution period with respect to a class of Series B Junior Securities or Series B Parity Securities is shorter than the Series B Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series B Junior Securities or Series B Parity Securities, so long as, at the time of declaration of such distribution, (i) there are no Series B Distributions in Arrears, and (ii) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series B Preferred Units on the next successive Series B Distribution Payment Date. Accumulated Series B Distributions in Arrears for any past Series B Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series B Distribution Payment Date, to Series B Holders on the Record Date for such payment, which may not be less

25

than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Series B Distributions in Arrears on all Outstanding Series B Preferred Units and all accumulated distributions in arrears on any Series B Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series B Preferred Units and accumulated distributions in arrears on any such Series B Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series B Preferred Units and any other Series B Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series B Preferred Units and any such other Series B Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series B Preferred Units and such other Series B Parity Securities at such time. Subject to Section 12.4 and Section 5.18(b)(v), Series B Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series B Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series B Distributions as described in Section 5.18(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series B Preferred Units. So long as the Series B Preferred Units are held of record by the Depositary or its nominee, declared Series B Distributions shall be paid to the Depositary in same-day funds on each Series B Distribution Payment Date or other distribution payment date in the case of payments for Series B Distributions in Arrears.

(C) The Series B Distribution Rate for each Series B Distribution Period in the Series B Floating Rate Period will be determined by the Calculation Agent using Three-Month LIBOR as in effect on the Distribution Determination Date for such Series B Distribution Period. The Calculation Agent then will add the spread of 4.155% per annum to Three-Month LIBOR as determined on the applicable Distribution Determination Date.

Notwithstanding the foregoing:

(A) If the Calculation Agent determines on the relevant Distribution Determination Date that the LIBOR base rate has been discontinued, then the Calculation Agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the LIBOR base rate, provided that if the Calculation Agent determines there is an industry-accepted substitute or successor base rate, then the Calculation Agent shall use such substitute or successor base rate; and

(B) If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine what business day convention to use, the definition of business day, the Distribution Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate.

(C) Unless otherwise determined by the General Partner, Series B Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series B Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series B Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.18(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series B Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences,

26

duties, or special rights of the Series B Preferred Units; provided, however, that (1) subject to Section 5.18(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.18(b)(iii)(B) and

(2) for purposes of this Section 5.18(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series B Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series B Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series B Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series B Preferred Units, voting as a class together with holders of any other Series B Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series B Parity Securities (including any additional Series B Preferred Units) if the cumulative distributions payable on Outstanding Series B Preferred Units (or any Series B Parity Securities, if the holders of such Series B Parity Securities vote as a class together with the Series B Holders pursuant to this Section 5.18(b)(iii)(C)) are in Arrears or (y) create or issue any Series B Senior Securities.

(D) For any matter described in this Section 5.18(b)(iii) in which the Series B Holders are entitled to vote as a class (whether separately or together with the holders of any Series B Parity Securities), such Series B Holders shall be entitled to one vote per Series B Preferred Unit. Any Series B Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Section 5.18(b)(iii)(B) and Section 5.18(b)(iii)(C), no vote of the Series B Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series B Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series B Rating Event.

(A) The Partnership shall have the right (1) at any time, and from time to time, on or after February 15, 2028 or (2) at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series B Rating Event, in each case, to redeem the Series B Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (2) of this Section 5.18(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series B Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series B Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (1) of this Section 5.18(b)(iv)(A)), or 102% (in the case of a redemption described in clause (2) of this Section 5.18(b)(iv)(A)), of the Series B Liquidation Preference for such Series B Preferred Unit on such Series B Redemption Date plus an amount equal to all unpaid Series B Distributions thereon from the date of issuance to, but excluding, the Series B Redemption Date (whether or not such distributions shall have been declared) (the “Series B Redemption Price”). So long as the Series B Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series B Redemption Price shall be paid by the Paying Agent to the Depositary on the Series B Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 15 days and not more than 60 days before the scheduled Series B Redemption Date to the Series B Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series B Preferred Units to be redeemed as such Series B Holders’ names appear on the books of the Transfer Agent and at the address of such Series B

27

Holders shown therein. Such notice (the “Series B Redemption Notice”) shall state, as applicable: (1) the Series B Redemption Date, (2) the number of Series B Preferred Units to be redeemed and, if less than all Outstanding Series B Preferred Units are to be redeemed, the number (and in the case of Series B Preferred Units in certificated form, the identification) of Series B Preferred Units to be redeemed from such Series B Holder, (3) the Series B Redemption Price, (4) the place where any Series B Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series B Redemption Price therefor (which shall occur automatically if the Certificate representing such Series B Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series B Preferred Units to be redeemed shall cease to accumulate from and after such Series B Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series B Preferred Units, the number of Series B Preferred Units to be redeemed shall be determined by the General Partner, and such Series B Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series B Preferred Units. The aggregate Series B Redemption Price for any such partial redemption of the Outstanding Series B Preferred Units shall be allocated correspondingly among the redeemed Series B Preferred Units. The Series B Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.18.

(D) If the Partnership gives or causes to be given a Series B Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series B Preferred Units as to which such Series B Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series B Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series B Redemption Price to each Series B Holder whose Series B Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series B Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series B Redemption Notice. If a Series B Redemption Notice shall have been given, from and after the Series B Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series B Redemption Notice, all Series B Distributions on such Series B Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series B Preferred Units as Limited Partners with respect to such Series B Preferred Units to be redeemed shall cease, except the right to receive the Series B Redemption Price, and such Series B Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series B Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent.

Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series B Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series B Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series B Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Series B Redemption Notice, there shall be no redemption of any Series B Preferred Units called for redemption until funds sufficient to pay the full Series B Redemption Price of such Series B Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series B Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series B Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series B Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying

28

Agent shall deliver to the Series B Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series B Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.18, in the event that full cumulative distributions on the Series B Preferred Units and any Series B Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series B Preferred Units or Series B Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series B Holders and holders of any Series B Parity Securities. Subject to Section 4.9, so long as any Series B Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series B Junior Securities unless full cumulative distributions on the Series B Preferred Units and any Series B Parity Securities for all prior and the then-ending Series B Distribution Periods, with respect to the Series B Preferred Units, and all prior and then ending distribution periods, with respect to any such Series B Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights. In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series B Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series B Senior Securities or Series B Parity Securities), (A) first, any accumulated and unpaid distributions on the Series B Preferred Units (regardless of whether previously declared) and (B) then, any positive value in each such holder’s Capital Account in respect of such Series B Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series B Preferred Units is less than the aggregate Series B Base Liquidation Preference of such Series B Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series B Parity Securities upon which like allocation and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series B Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series B Preferred Unit is equal to the Series B Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series B Parity Securities (including pursuant to Sections 5.17(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series B Preferred Units and such Series B Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series B Preferred Unit and such Series B Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series B Preferred Units is less than the aggregate Series B Base Liquidation Preference of such Series B Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series B Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series B Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series B Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the

29

effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series B Parity Securities (including pursuant to Sections 5.17(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series B Preferred Units and such Series B Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series B Preferred Unit and such Series B Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series B Preferred Units, and any Series B Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series B Preferred Units shall become entitled to receive any distributions in respect of the Series B Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series B Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series B Senior Securities or Series B Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series B Preferred Units.

(vi) Rank. The Series B Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series B Junior Securities;

(B) on a parity with any Series B Parity Securities;

(C) junior to any Series B Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund. The Series B Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders. To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series B Holder as the true, lawful, and absolute owner of the applicable Series B Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series B Preferred Units may be listed or admitted to trading, if any.

(ix) Other Rights; Fiduciary Duties. The Series B Preferred Units and the Series B Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series B Holders, other than the implied contractual covenant of good faith and fair dealing.

“Section 5.19 Establishment of Series C Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “7.375% Series C Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units” (the “Series C Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.19. Each Series C Preferred Unit shall be identical in all respects to every other

30

Series C Preferred Unit, except as to the respective dates from which the Series C Liquidation Preference shall increase or from which Series C Distributions may begin accruing, to the extent such dates may differ. The Series C Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series C Holder for conversion or, except as set forth in Section 5.19(b)(iv), redemption thereof at a particular date.

(b) Rights of Series C Preferred Units. The Series C Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series C Preferred Units.

(A) The authorized number of Series C Preferred Units shall be unlimited. Series C Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series C Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series C Holder shall be entitled to receive a definitive Certificate evidencing its Series C Preferred Units, unless (1) requested by a Series C Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series C Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series C Preferred Units, payments and communications made by the Partnership to Series C Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series C Preferred Unit shall be cumulative and shall accumulate at the applicable Series C Distribution Rate from and including February 16, 2021 (or, for any subsequently issued and newly Outstanding Series C Preferred Units, from and including the Series C Distribution Payment Date immediately preceding the issue date of such Series C Preferred Units) until such time as the Partnership pays the Series C Distribution or redeems such Series C Preferred Unit in accordance with Section 5.19(b)(iv), whether or not such Series C Distributions shall have been declared. Series C Holders shall be entitled to receive Series C Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series C Distribution Rate per Series C Preferred Unit when, as, and, if declared by the General Partner. Series C Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.19(b)(ii), shall be paid, in Arrears, on each Series C Distribution Payment Date. Series C Distributions shall accumulate in each Series C Distribution Period from and including the preceding Series C Distribution Payment Date (other than the initial Series C Distribution Period, which shall commence on and include February 16, 2021), to, but excluding, the next Series C Distribution Payment Date for such Series C Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series C Distributions at the Series C Distribution Rate. If any Series C Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series C Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. During the Series C Fixed Rate Period, Series C Distributions shall be payable based on a 360-day year consisting of twelve 30 day months. During the Series C Floating Rate Period, Series C Distributions shall be computed by multiplying the Series C Distribution Rate by a fraction, the numerator of which will be the actual number of days elapsed during that Series C Distribution Period (determined by including the first day of such Series C Distribution Period and excluding the last day, which is the Series C Distribution Payment Date), and the denominator of which will be 360, and by multiplying the result by the aggregate Series C Liquidation Preference of all Outstanding Series C Preferred Units. All Series C Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership

31

pursuant to this Section 5.19(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series C Distribution Period shall be for the account of the holders of Series C Preferred Units as of the applicable Series C Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series C Distribution Payment Date, the Partnership shall pay those Series C Distributions, if any, that shall have been declared by the General Partner to Series C Holders on the Record Date for the applicable Series C Distribution. The Record Date (the “Series C Distribution Record Date”) for the payment of any Series C Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series C Distribution Payment Date, except that in the case of payments of Series C Distributions in Arrears, the Series C Distribution Record Date with respect to a Series C Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.19. So long as any Series C Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series C Junior Securities (other than a distribution payable solely in Series C Junior Securities) unless full cumulative Series C Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series C Preferred Units (and distributions on any other Series C Parity Securities) through the most recent respective Series C Distribution Payment Date (and distribution payment date with respect to such Series C Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.19(b)(ii)(B), if a distribution period with respect to a class of Series C Junior Securities or Series C Parity Securities is shorter than the Series C Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series C Junior Securities or Series C Parity Securities, so long as, at the time of declaration of such distribution, (1) there are no Series C Distributions in Arrears, and (2) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series C Preferred Units on the next successive Series C Distribution Payment Date. Accumulated Series C Distributions in Arrears for any past Series C Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series C Distribution Payment Date, to Series C Holders on the Record Date for such payment, which may not be less than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Series C Distributions in Arrears on all Outstanding Series C Preferred Units and all accumulated distributions in arrears on any Series C Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series C Preferred Units and accumulated distributions in arrears on any such Series C Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series C Preferred Units and any other Series C Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series C Preferred Units and any such other Series C Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series C Preferred Units and such other Series C Parity Securities at such time. Subject to Section 12.4 and Section 5.19(b)(v), Series C Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series C Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series C Distributions as described in Section 5.19(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series C Preferred Units. So long as the Series C Preferred Units are held of record by the Depositary or its nominee, declared Series C Distributions shall be paid to the Depositary in same-day funds on each Series C Distribution Payment Date or other distribution payment date in the case of payments for Series C Distributions in Arrears.

32

(C) The Series C Distribution Rate for each Series C Distribution Period in the Series C Floating Rate Period will be determined by the Calculation Agent using Three-Month LIBOR as in effect on the Distribution Determination Date for such Series C Distribution Period. The Calculation Agent then will add the spread of 4.530% per annum to Three-Month LIBOR as determined on the applicable Distribution Determination Date.

Notwithstanding the foregoing:

(A) If the Calculation Agent determines on the relevant Distribution Determination Date that the LIBOR base rate has been discontinued, then the Calculation Agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the LIBOR base rate, provided that if the Calculation Agent determines there is an industry-accepted substitute or successor base rate, then the Calculation Agent shall use such substitute or successor base rate.

(B) If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine what business day convention to use, the definition of business day, the Distribution Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate.

(C) Unless otherwise determined by the General Partner, Series C Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series C Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series C Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.19(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series C Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series C Preferred Units; provided, however, that (1) subject to Section 5.19(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.19(b)(iii)(B) and (2) for purposes of this Section 5.19(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series C Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series C Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series C Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series C Preferred Units, voting as a class together with holders of any other Series C Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series C Parity Securities (including any additional Series C Preferred Units) if the cumulative distributions payable on Outstanding Series C Preferred Units (or any Series C Parity Securities, if the holders of such Series C Parity Securities vote as a class together with the Series C Holders pursuant to this Section 5.19(b)(iii)(C)) are in Arrears or (y) create or issue any Series C Senior Securities.

(D) For any matter described in this Section 5.19(b)(iii) in which the Series C Holders are entitled to vote as a class (whether separately or together with the holders of any Series C Parity

33

Securities), such Series C Holders shall be entitled to one vote per Series C Preferred Unit. Any Series C Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Sections 5.19(b)(iii)(B) and 5.19(b)(iii)(C), no vote of the Series C Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series C Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series C Rating Event.

(A) The Partnership shall have the right (1) at any time, and from time to time, on or after May 15, 2023 or (2) at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series C Rating Event, in each case, to redeem the Series C Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (2) of this Section 5.19(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series C Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series C Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (1) of this Section 5.19(b)(iv)(A)), or 102% (in the case of a redemption described in clause (2) of this Section 5.19(b)(iv)(A)), of the Series C Liquidation Preference for such Series C Preferred Unit on such Series C Redemption Date plus an amount equal to all unpaid Series C Distributions thereon from the date of issuance to, but excluding, the Series C Redemption Date (whether or not such distributions shall have been declared) (the “Series C Redemption Price”). So long as the Series C Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series C Redemption Price shall be paid by the Paying Agent to the Depositary on the Series C Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled Series C Redemption Date to the Series C Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series C Preferred Units to be redeemed as such Series C Holders’ names appear on the books of the Transfer Agent and at the address of such Series C Holders shown therein. Such notice (the “Series C Redemption Notice”) shall state, as applicable: (1) the Series C Redemption Date, (2) the number of Series C Preferred Units to be redeemed and, if less than all Outstanding Series C Preferred Units are to be redeemed, the number (and in the case of Series C Preferred Units in certificated form, the identification) of Series C Preferred Units to be redeemed from such Series C Holder, (3) the Series C Redemption Price, (4) the place where any Series C Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series C Redemption Price therefor (which shall occur automatically if the Certificate representing such Series C Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series C Preferred Units to be redeemed shall cease to accumulate from and after such Series C Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series C Preferred Units, the number of Series C Preferred Units to be redeemed shall be determined by the General Partner, and such Series C Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series C Preferred Units. The aggregate Series C Redemption Price for any such partial redemption of the Outstanding Series C Preferred Units shall be allocated correspondingly among the redeemed Series C Preferred Units. The Series C Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.19.

(D) If the Partnership gives or causes to be given a Series C Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series C Preferred

34

Units as to which such Series C Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series C Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series C Redemption Price to each Series C Holder whose Series C Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series C Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series C Redemption Notice. If a Series C Redemption Notice shall have been given, from and after the Series C Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series C Redemption Notice, all Series C Distributions on such Series C Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series C Preferred Units as Limited Partners with respect to such Series C Preferred Units to be redeemed shall cease, except the right to receive the Series C Redemption Price, and such Series C Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series C Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series C Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series C Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series C Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Series C Redemption Notice, there shall be no redemption of any Series C Preferred Units called for redemption until funds sufficient to pay the full Series C Redemption Price of such Series C Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series C Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series C Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series C Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series C Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series C Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.19, in the event that full cumulative distributions on the Series C Preferred Units and any Series C Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series C Preferred Units or Series C Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series C Holders and holders of any Series C Parity Securities. Subject to Section 4.9, so long as any Series C Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series C Junior Securities unless full cumulative distributions on the Series C Preferred Units and any Series C Parity Securities for all prior and the then-ending Series C Distribution Periods, with respect to the Series C Preferred Units, and all prior and then ending distribution periods, with respect to any such Series C Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights. In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series C Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record

35

Holders of any other class or series of Partnership Interests (other than Series C Senior Securities or Series C Parity Securities), (1) first, any accumulated and unpaid distributions on the Series C Preferred Units (regardless of whether previously declared) and (2) then, any positive value in each such holder’s Capital Account in respect of such Series C Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series C Preferred Units is less than the aggregate Series C Base Liquidation Preference of such Series C Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series C Parity Securities upon which like allocation and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series C Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series C Preferred Unit is equal to the Series C Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series C Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series C Preferred Units and such Series C Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series C Preferred Unit and such Series C Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series C Preferred Units is less than the aggregate Series C Base Liquidation Preference of such Series C Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series C Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series C Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series C Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series C Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.20(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series C Preferred Units and such Series C Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series C Preferred Unit and such Series C Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series C Preferred Units and any Series C Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series C Preferred Units shall become entitled to receive any distributions in respect of the Series C Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series C Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series C Senior Securities or Series C Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series C Preferred Units.

36

(vi) Rank. The Series C Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series C Junior Securities;

(B) on a parity with any Series C Parity Securities;

(C) junior to any Series C Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund. The Series C Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders. To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series C Holder as the true, lawful, and absolute owner of the applicable Series C Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series C Preferred Units may be listed or admitted to trading, if any.

(ix) Other Rights; Fiduciary Duties. The Series C Preferred Units and the Series C Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series C Holders, other than the implied contractual covenant of good faith and fair dealing.

“Section 5.20 Establishment of Series D Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “7.625% Series D Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units” (the “Series D Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.20. Each Series D Preferred Unit shall be identical in all respects to every other Series D Preferred Unit, except as to the respective dates from which the Series D Liquidation Preference shall increase or from which Series D Distributions may begin accruing, to the extent such dates may differ. The Series D Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series D Holder for conversion or, except as set forth in Section 5.20(b)(iv), redemption thereof at a particular date.

(b) Rights of Series D Preferred Units. The Series D Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series D Preferred Units.

(A) The authorized number of Series D Preferred Units shall be unlimited. Series D Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series D Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series D Holder shall be entitled to receive a definitive Certificate evidencing its Series D Preferred Units, unless (1) requested by a Series D Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series D Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series D Preferred Units, payments and

37

communications made by the Partnership to Series D Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series D Preferred Unit shall be cumulative and shall accumulate at the applicable Series D Distribution Rate from and including February 16, 2021 (or, for any subsequently issued and newly Outstanding Series D Preferred Units, from and including the Series D Distribution Payment Date immediately preceding the issue date of such Series D Preferred Units) until such time as the Partnership pays the Series D Distribution or redeems such Series D Preferred Unit in accordance with Section 5.20(b)(iv), whether or not such Series D Distributions shall have been declared. Series D Holders shall be entitled to receive Series D Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series D Distribution Rate per Series D Preferred Unit when, as, and, if declared by the General Partner. Series D Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.20(b)(ii), shall be paid, in Arrears, on each Series D Distribution Payment Date. Series D Distributions shall accumulate in each Series D Distribution Period from and including the preceding Series D Distribution Payment Date (other than the initial Series D Distribution Period, which shall commence on and include February 16, 2021), to, but excluding, the next Series D Distribution Payment Date for such Series D Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series D Distributions at the Series D Distribution Rate. If any Series D Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series D Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. During the Series D Fixed Rate Period, Series D Distributions shall be payable based on a 360-day year consisting of twelve 30 day months. During the Series D Floating Rate Period, Series D Distributions shall be computed by multiplying the Series D Distribution Rate by a fraction, the numerator of which will be the actual number of days elapsed during that Series D Distribution Period (determined by including the first day of such Series D Distribution Period and excluding the last day, which is the Series D Distribution Payment Date), and the denominator of which will be 360, and by multiplying the result by the aggregate Series D Liquidation Preference of all Outstanding Series D Preferred Units. All Series D Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.20(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series D Distribution Period shall be for the account of the holders of Series D Preferred Units as of the applicable Series D Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series D Distribution Payment Date, the Partnership shall pay those Series D Distributions, if any, that shall have been declared by the General Partner to Series D Holders on the Record Date for the applicable Series D Distribution. The Record Date (the “Series D Distribution Record Date”) for the payment of any Series D Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series D Distribution Payment Date, except that in the case of payments of Series D Distributions in Arrears, the Series D Distribution Record Date with respect to a Series D Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.20. So long as any Series D Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series D Junior Securities (other than a distribution payable solely in Series D Junior Securities) unless full cumulative Series D Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series D Preferred Units (and distributions on any other Series D Parity Securities) through the most recent respective Series D Distribution Payment Date (and

38

distribution payment date with respect to such Series D Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.20(b)(ii)(B), if a distribution period with respect to a class of Series D Junior Securities or Series D Parity Securities is shorter than the Series D Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series D Junior Securities or Series D Parity Securities, so long as, at the time of declaration of such distribution, (1) there are no Series D Distributions in Arrears, and (2) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series D Preferred Units on the next successive Series D Distribution Payment Date. Accumulated Series D Distributions in Arrears for any past Series D Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series D Distribution Payment Date, to Series D Holders on the Record Date for such payment, which may not be less than 10 days before such payment date. Subject to the next succeeding sentence, if all accumulated Series D Distributions in Arrears on all Outstanding Series D Preferred Units and all accumulated distributions in arrears on any Series D Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series D Preferred Units and accumulated distributions in arrears on any such Series D Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series D Preferred Units and any other Series D Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series D Preferred Units and any such other Series D Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series D Preferred Units and such other Series D Parity Securities at such time. Subject to Section 12.4 and Section 5.20(b)(v), Series D Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series D Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series D Distributions as described in Section 5.20(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series D Preferred Units. So long as the Series D Preferred Units are held of record by the Depositary or its nominee, declared Series D Distributions shall be paid to the Depositary in same-day funds on each Series D Distribution Payment Date or other distribution payment date in the case of payments for Series D Distributions in Arrears.

(C) The Series D Distribution Rate for each Series D Distribution Period in the Series D Floating Rate Period will be determined by the Calculation Agent using Three-Month LIBOR as in effect on the Distribution Determination Date for such Series D Distribution Period. The Calculation Agent then will add the spread of 4.738% per annum to Three-Month LIBOR as determined on the applicable Distribution Determination Date.

Notwithstanding the foregoing:

(A) If the Calculation Agent determines on the relevant Distribution Determination Date that the LIBOR base rate has been discontinued, then the Calculation Agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the LIBOR base rate, provided that if the Calculation Agent determines there is an industry-accepted substitute or successor base rate, then the Calculation Agent shall use such substitute or successor base rate.

(B) If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine what business day convention to use, the definition of business day, the Distribution Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate.

39

(C) Unless otherwise determined by the General Partner, Series D Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series D Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series D Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.20(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series D Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series D Preferred Units; provided, however, that (1) subject to Section 5.20(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.20(b)(iii)(B) and (2) for purposes of this Section 5.20(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series D Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series D Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series D Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series D Preferred Units, voting as a class together with holders of any other Series D Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series D Parity Securities (including any additional Series D Preferred Units) if the cumulative distributions payable on Outstanding Series D Preferred Units (or any Series D Parity Securities, if the holders of such Series D Parity Securities vote as a class together with the Series D Holders pursuant to this Section 5.20(b)(iii)(C)) are in Arrears or (y) create or issue any Series D Senior Securities.

(D) For any matter described in this Section 5.20(b)(iii) in which the Series D Holders are entitled to vote as a class (whether separately or together with the holders of any Series D Parity Securities), such Series D Holders shall be entitled to one vote per Series D Preferred Unit. Any Series D Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Sections 5.20(b)(iii)(B) and 5.20(b)(iii)(C), no vote of the Series D Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series D Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series D Rating Event.

(A) The Partnership shall have the right (1) at any time, and from time to time, on or after August 15, 2023 or (2) at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series D Rating Event, in each case, to redeem the Series D Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (2) of this Section 5.20(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series D Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series D Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (1) of this Section 5.20(b)(iv)(A)), or 102% (in the case of a redemption described in clause (2) of this Section 5.20(b)(iv)(A)), of the Series D Liquidation Preference for such Series D Preferred Unit on such Series D Redemption Date plus an amount equal to all unpaid Series D Distributions

40

thereon from the date of issuance to, but excluding, the Series D Redemption Date (whether or not such distributions shall have been declared) (the “Series D Redemption Price”). So long as the Series D Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series D Redemption Price shall be paid by the Paying Agent to the Depositary on the Series D Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled Series D Redemption Date to the Series D Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series D Preferred Units to be redeemed as such Series D Holders’ names appear on the books of the Transfer Agent and at the address of such Series D Holders shown therein. Such notice (the “Series D Redemption Notice”) shall state, as applicable: (1) the Series D Redemption Date, (2) the number of Series D Preferred Units to be redeemed and, if less than all Outstanding Series D Preferred Units are to be redeemed, the number (and in the case of Series D Preferred Units in certificated form, the identification) of Series D Preferred Units to be redeemed from such Series D Holder, (3) the Series D Redemption Price, (4) the place where any Series D Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series D Redemption Price therefor (which shall occur automatically if the Certificate representing such Series D Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series D Preferred Units to be redeemed shall cease to accumulate from and after such Series D Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series D Preferred Units, the number of Series D Preferred Units to be redeemed shall be determined by the General Partner, and such Series D Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series D Preferred Units. The aggregate Series D Redemption Price for any such partial redemption of the Outstanding Series D Preferred Units shall be allocated correspondingly among the redeemed Series D Preferred Units. The Series D Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.20.

(D) If the Partnership gives or causes to be given a Series D Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series D Preferred Units as to which such Series D Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series D Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series D Redemption Price to each Series D Holder whose Series D Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series D Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series D Redemption Notice. If a Series D Redemption Notice shall have been given, from and after the Series D Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series D Redemption Notice, all Series D Distributions on such Series D Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series D Preferred Units as Limited Partners with respect to such Series D Preferred Units to be redeemed shall cease, except the right to receive the Series D Redemption Price, and such Series D Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series D Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series D Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series D Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series D Holders entitled to such redemption

41

or other payment shall have recourse only to the Partnership. Notwithstanding any Series D Redemption Notice, there shall be no redemption of any Series D Preferred Units called for redemption until funds sufficient to pay the full Series D Redemption Price of such Series D Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series D Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series D Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series D Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series D Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series D Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.20, in the event that full cumulative distributions on the Series D Preferred Units and any Series D Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series D Preferred Units or Series D Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series D Holders and holders of any Series D Parity Securities. Subject to Section 4.9, so long as any Series D Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series D Junior Securities unless full cumulative distributions on the Series D Preferred Units and any Series D Parity Securities for all prior and the then-ending Series D Distribution Periods, with respect to the Series D Preferred Units, and all prior and then ending distribution periods, with respect to any such Series D Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights. In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series D Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series D Senior Securities or Series D Parity Securities), (A) first, any accumulated and unpaid distributions on the Series D Preferred Units (regardless of whether previously declared) and (B) then, any positive value in each such holder’s Capital Account in respect of such Series D Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series D Preferred Units is less than the aggregate Series D Base Liquidation Preference of such Series D Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series D Parity Securities upon which like allocation and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series D Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series D Preferred Unit is equal to the Series D Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series D Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series D Preferred Units and such Series D Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series D Preferred Unit and such Series D Parity Security is equal to the applicable liquidation preference (and no other allocation

42

pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series D Preferred Units is less than the aggregate Series D Base Liquidation Preference of such Series D Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series D Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series D Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series D Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series D Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.21(b)(v), 5.22(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series D Preferred Units and such Series D Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series D Preferred Unit and such Series D Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series D Preferred Units and any Series D Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series D Preferred Units shall become entitled to receive any distributions in respect of the Series D Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series D Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series D Senior Securities or Series D Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series D Preferred Units.

(vi) Rank. The Series D Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series D Junior Securities;

(B) on a parity with any Series D Parity Securities;

(C) junior to any Series D Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund. The Series D Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders. To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series D Holder as the true, lawful, and absolute owner of the applicable Series D Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series D Preferred Units may be listed or admitted to trading, if any.

(ix) Other Rights; Fiduciary Duties. The Series D Preferred Units and the Series D Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this

43

Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series D Holders, other than the implied contractual covenant of good faith and fair dealing.

“Section 5.21 Establishment of Series E Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “7.600% Series E Fixed-to-Floating Rate Cumulative Redeemable Perpetual Preferred Units” (the “Series E Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.21. Each Series E Preferred Unit shall be identical in all respects to every other Series E Preferred Unit, except as to the respective dates from which the Series E Liquidation Preference shall increase or from which Series E Distributions may begin accruing, to the extent such dates may differ. The Series E Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series E Holder for conversion or, except as set forth in Section 5.21(b)(iv), redemption thereof at a particular date.

(b) Rights of Series E Preferred Units. The Series E Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series E Preferred Units.

(A) The authorized number of Series E Preferred Units shall be unlimited. Series E Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series E Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series E Holder shall be entitled to receive a definitive Certificate evidencing its Series E Preferred Units, unless (1) requested by a Series E Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series E Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series E Preferred Units, payments and communications made by the Partnership to Series E Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series E Preferred Unit shall be cumulative and shall accumulate at the applicable Series E Distribution Rate from and including February 16, 2021 (or, for any subsequently issued and newly Outstanding Series E Preferred Units, from and including the Series E Distribution Payment Date immediately preceding the issue date of such Series E Preferred Units) until such time as the Partnership pays the Series E Distribution or redeems such Series E Preferred Unit in accordance with Section 5.21(b)(iv), whether or not such Series E Distributions shall have been declared. Series E Holders shall be entitled to receive Series E Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series E Distribution Rate per Series E Preferred Unit when, as, and, if declared by the General Partner. Series E Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.21(b)(ii), shall be paid, in Arrears, on each Series E Distribution Payment Date. Series E Distributions shall accumulate in each Series E Distribution Period from and including the preceding Series E Distribution Payment Date (other than the initial Series E Distribution Period, which shall commence on and include February 16, 2021), to, but excluding, the next Series E Distribution Payment Date for such Series E Distribution Period; provided that distributions shall accrue on accumulated

44

but unpaid Series E Distributions at the Series E Distribution Rate. If any Series E Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series E Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions.

During the Series E Fixed Rate Period, Series E Distributions shall be payable based on a 360- day year consisting of twelve 30 day months. During the Series E Floating Rate Period, Series E Distributions shall be computed by multiplying the Series E Distribution Rate by a fraction, the numerator of which will be the actual number of days elapsed during that Series E Distribution Period (determined by including the first day of such Series E Distribution Period and excluding the last day, which is the Series E Distribution Payment Date), and the denominator of which will be 360, and by multiplying the result by the aggregate Series E Liquidation Preference of all Outstanding Series E Preferred Units. All Series E Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.21(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series E Distribution Period shall be for the account of the holders of Series E Preferred Units as of the applicable Series E Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series E Distribution Payment Date, the Partnership shall pay those Series E Distributions, if any, that shall have been declared by the General Partner to Series E Holders on the Record Date for the applicable Series E Distribution. The Record Date (the “Series E Distribution Record Date”) for the payment of any Series E Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series E Distribution Payment Date, except that in the case of payments of Series E Distributions in Arrears, the Series E Distribution Record Date with respect to a Series E Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.21. So long as any Series E Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series E Junior Securities (other than a distribution payable solely in Series E Junior Securities) unless full cumulative Series E Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series E Preferred Units (and distributions on any other Series E Parity Securities) through the most recent respective Series E Distribution Payment Date (and distribution payment date with respect to such Series E Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.21(b)(ii)(B), if a distribution period with respect to a class of Series E Junior Securities or Series E Parity Securities is shorter than the Series E Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series E Junior Securities or Series E Parity Securities, so long as, at the time of declaration of such distribution, (i) there are no Series E Distributions in Arrears, and (ii) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series E Preferred Units on the next successive Series E Distribution Payment Date. Accumulated Series E Distributions in Arrears for any past Series E Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series E Distribution Payment Date, to Series E Holders on the Record Date for such payment, which may not be less than 10 days before such payment date.

Subject to the next succeeding sentence, if all accumulated Series E Distributions in Arrears on all Outstanding Series E Preferred Units and all accumulated distributions in arrears on any Series E Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series E Preferred Units and accumulated distributions in arrears on any such Series E Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all

45

Series E Preferred Units and any other Series E Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series E Preferred Units and any such other Series E Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series E Preferred Units and such other Series E Parity Securities at such time. Subject to Section 12.4 and Section 5.21(b)(v), Series E Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series E Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series E Distributions as described in Section 5.21(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series E Preferred Units. So long as the Series E Preferred Units are held of record by the Depositary or its nominee, declared Series E Distributions shall be paid to the Depositary in same-day funds on each Series E Distribution Payment Date or other distribution payment date in the case of payments for Series E Distributions in Arrears.

(C) The Series E Distribution Rate for each Series E Distribution Period in the Series E Floating Rate Period will be determined by the Calculation Agent using Three-Month LIBOR as in effect on the Distribution Determination Date for such Series E Distribution Period. The Calculation Agent then will add the spread of 5.161% per annum to Three-Month LIBOR as determined on the applicable Distribution Determination Date.

Notwithstanding the foregoing:

(a) If the Calculation Agent determines on the relevant Distribution Determination Date that the LIBOR base rate has been discontinued, then the Calculation Agent will use a substitute or successor base rate that it has determined in its sole discretion is most comparable to the LIBOR base rate, provided that if the Calculation Agent determines there is an industry-accepted substitute or successor base rate, then the Calculation Agent shall use such substitute or successor base rate.

(b) If the Calculation Agent has determined a substitute or successor base rate in accordance with the foregoing, the Calculation Agent in its sole discretion may determine what business day convention to use, the definition of business day, the Distribution Determination Date to be used and any other relevant methodology for calculating such substitute or successor base rate.

(c) Unless otherwise determined by the General Partner, Series E Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series E Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series E Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.21(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series E Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series E Preferred Units; provided, however, that (i) subject to Section 5.21(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.21(b)(iii)(B) and (ii) for purposes of this Section 5.21(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series E Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series E Holders (as determined by the General

46

Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series E Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series E Preferred Units, voting as a class together with holders of any other Series E Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series E Parity Securities (including any additional Series E Preferred Units) if the cumulative distributions payable on Outstanding Series E Preferred Units (or any Series E Parity Securities, if the holders of such Series E Parity Securities vote as a class together with the Series E Holders pursuant to this Section 5.21(b)(iii)(C)) are in Arrears or (y) create or issue any Series E Senior Securities.

(D) For any matter described in this Section 5.21(b)(iii) in which the Series E Holders are entitled to vote as a class (whether separately or together with the holders of any Series E Parity Securities), such Series E Holders shall be entitled to one vote per Series E Preferred Unit. Any Series E Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Sections 5.21(b)(iii)(B) and 5.21(b)(iii)(C), no vote of the Series E Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series E Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series E Rating Event.

(A) The Partnership shall have the right (i) at any time, and from time to time, on or after May 15, 2024 or (ii) at any time within 120 days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series E Rating Event, in each case, to redeem the Series E Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (ii) of this Section 5.21(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series E Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series E Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (i) of this Section 5.21(b)(iv)(A)), or 102% (in the case of a redemption described in clause (ii) of this Section 5.21(b)(iv)(A)), of the Series E Liquidation Preference for such Series E Preferred Unit on such Series E Redemption Date plus an amount equal to all unpaid Series E Distributions thereon from the date of issuance to, but excluding, the Series E Redemption Date (whether or not such distributions shall have been declared) (the “Series E Redemption Price”). So long as the Series E Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series E Redemption Price shall be paid by the Paying Agent to the Depositary on the Series E Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 30 days and not more than 60 days before the scheduled Series E Redemption Date to the Series E Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series E Preferred Units to be redeemed as such Series E Holders’ names appear on the books of the Transfer Agent and at the address of such Series E Holders shown therein. Such notice (the “Series E Redemption Notice”) shall state, as applicable: (1) the Series E Redemption Date, (2) the number of Series E Preferred Units to be redeemed and, if less than all Outstanding Series E Preferred Units are to be redeemed, the number (and in the case of Series E Preferred Units in certificated form, the identification) of Series E Preferred Units to be redeemed from such Series E Holder, (3) the Series E Redemption Price, (4) the place where any Series E Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series E Redemption Price therefor (which shall occur automatically if the Certificate representing such Series E Preferred Units is issued in the name of

47

the Depositary or its nominee), and (5) that distributions on the Series E Preferred Units to be redeemed shall cease to accumulate from and after such Series E Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series E Preferred Units, the number of Series E Preferred Units to be redeemed shall be determined by the General Partner, and such Series E Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series E Preferred Units. The aggregate Series E Redemption Price for any such partial redemption of the Outstanding Series E Preferred Units shall be allocated correspondingly among the redeemed Series E Preferred Units. The Series E Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.21.

(D) If the Partnership gives or causes to be given a Series E Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series E Preferred Units as to which such Series E Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series E Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series E Redemption Price to each Series E Holder whose Series E Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series E Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series E Redemption Notice. If a Series E Redemption Notice shall have been given, from and after the Series E Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series E Redemption Notice, all Series E Distributions on such Series E Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series E Preferred Units as Limited Partners with respect to such Series E Preferred Units to be redeemed shall cease, except the right to receive the Series E Redemption Price, and such Series E Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series E Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series E Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series E Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series E Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Series E Redemption Notice, there shall be no redemption of any Series E Preferred Units called for redemption until funds sufficient to pay the full Series E Redemption Price of such Series E Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series E Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series E Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series E Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series E Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series E Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.21, in the event that full cumulative distributions on the Series E Preferred Units and any Series E Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series E Preferred Units or Series E Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series E Holders and holders of any Series E Parity Securities. Subject to

48

Section 4.9, so long as any Series E Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series E Junior Securities unless full cumulative distributions on the Series E Preferred Units and any Series E Parity Securities for all prior and the then-ending Series E Distribution Periods, with respect to the Series E Preferred Units, and all prior and then ending distribution periods, with respect to any such Series E Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights.

In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series E Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series E Senior Securities or Series E Parity Securities), (i) first, any accumulated and unpaid distributions on the Series E Preferred Units (regardless of whether previously declared) and (ii) then, any positive value in each such holder’s Capital Account in respect of such Series E Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series E Preferred Units is less than the aggregate Series E Base Liquidation Preference of such Series E Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series E Parity Securities upon which like allocation and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series E Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series E Preferred Unit is equal to the Series E Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series E Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.22(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series E Preferred Units and such Series E Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series E Preferred Unit and such Series E Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series E Preferred Units is less than the aggregate Series E Base Liquidation Preference of such Series E Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series E Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series E Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series E Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series E Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20 (b)(v), 5.22(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series E Preferred Units and such Series E Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series E Preferred Unit and such Series E Parity Security after making allocations pursuant to this and the immediately preceding sentence

49

is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series E Preferred Units and any Series E Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series E Preferred Units shall become entitled to receive any distributions in respect of the Series E Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series E Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series E Senior Securities or Series E Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series E Preferred Units.

(vi) Rank.

The Series E Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series E Junior Securities;

(B) on a parity with any Series E Parity Securities;

(C) junior to any Series E Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund.

The Series E Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders.

To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series E Holder as the true, lawful, and absolute owner of the applicable Series E Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series E Preferred Units may be listed or admitted to trading, if any.

(ix) Other Rights; Fiduciary Duties.

The Series E Preferred Units and the Series E Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series E Holders, other than the implied contractual covenant of good faith and fair dealing.”

“Section 5.22 Establishment of Series F Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “6.750% Series F Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units” (the

50

“Series F Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.22. Each Series F Preferred Unit shall be identical in all respects to every other Series F Preferred Unit, except as to the respective dates from which the Series F Liquidation Preference shall increase or from which Series F Distributions may begin accruing, to the extent such dates may differ. The Series F Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series F Holder for conversion or, except as set forth in Section 5.22(b)(iv), redemption thereof at a particular date.

(b) Rights of Series F Preferred Units. The Series F Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series F Preferred Units.

(A) The authorized number of Series F Preferred Units shall be unlimited. Series F Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series F Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series F Holder shall be entitled to receive a definitive Certificate evidencing its Series F Preferred Units, unless (1) requested by a Series F Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series F Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series F Preferred Units, payments and communications made by the Partnership to Series F Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series F Preferred Unit shall be cumulative and shall accumulate at the applicable Series F Distribution Rate from and including November 16, 2020 (or, for any subsequently issued and newly Outstanding Series F Preferred Units, from and including the Series F Distribution Payment Date immediately preceding the issue date of such Series F Preferred Units) until such time as the Partnership pays the Series F Distribution or redeems such Series F Preferred Unit in accordance with Section 5.22(b)(iv), whether or not such Series F Distributions shall have been declared. Series F Holders shall be entitled to receive Series F Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series F Distribution Rate per Series F Preferred Unit when, as, and, if declared by the General Partner. Series F Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.22(b)(ii), shall be paid, in Arrears, on each Series F Distribution Payment Date. Series F Distributions shall accumulate in each Series F Distribution Period from and including the preceding Series F Distribution Payment Date (other than the initial Series F Distribution Period, which shall commence on and include November 16, 2020), to, but excluding, the next Series F Distribution Payment Date for such Series F Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series F Distributions at the Series F Distribution Rate. If any Series F Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series F Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. All Series F Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.22(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series F Distribution Period shall be for the account of the holders of Series F Preferred Units as of the applicable Series F Distribution Record Date.

51

(B) Not later than 5:00 p.m., New York City time, on each Series F Distribution Payment Date, the Partnership shall pay those Series F Distributions, if any, that shall have been declared by the General Partner to Series F Holders on the Record Date for the applicable Series F Distribution. The Record Date (the “Series F Distribution Record Date”) for the payment of any Series F Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series F Distribution Payment Date, except that in the case of payments of Series F Distributions in Arrears, the Series F Distribution Record Date with respect to a Series F Distribution Payment Date shall be such date as may be designated by the General Partner in accordance with this Section 5.22. So long as any Series F Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series F Junior Securities (other than a distribution payable solely in Series F Junior Securities) unless full cumulative Series F Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series F Preferred Units (and distributions on any other Series F Parity Securities) through the most recent respective Series F Distribution Payment Date (and distribution payment date with respect to such Series F Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.22(b)(ii)(B), if a distribution period with respect to a class of Series F Junior Securities or Series F Parity Securities is shorter than the Series F Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series F Junior Securities or Series F Parity Securities, so long as, at the time of declaration of such distribution, (i) there are no Series F Distributions in Arrears, and (ii) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series F Preferred Units on the next successive Series F Distribution Payment Date. Accumulated Series F Distributions in Arrears for any past Series F Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series F Distribution Payment Date, to Series F Holders on the Record Date for such payment, which may not be less than 10 calendar days before such payment date. Subject to the next succeeding sentence, if all accumulated Series F Distributions in Arrears on all Outstanding Series F Preferred Units and all accumulated distributions in arrears on any Series F Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series F Preferred Units and accumulated distributions in arrears on any such Series F Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series F Preferred Units and any other Series F Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series F Preferred Units and any such other Series F Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series F Preferred Units and such other Series F Parity Securities at such time. Subject to Section 12.4 and Section 5.22 (b)(v), Series F Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series F Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series F Distributions as described in Section 5.22(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series F Preferred Units. So long as the Series F Preferred Units are held of record by the Depositary or its nominee, declared Series F Distributions shall be paid to the Depositary in same-day funds on each Series F Distribution Payment Date or other distribution payment date in the case of payments for Series F Distributions in Arrears.

(C) The Series F Distribution Rate for each Series F Reset Period will be determined by the Calculation Agent for the Series F Preferred Units using the Series F Five-year U.S. Treasury Rate, as of the applicable Series F Reset Distribution Determination Date for such Series F Reset Period. The Calculation Agent for the Series F Preferred Units then will add the spread of 5.134% per annum to the Series F Five-year U.S. Treasury Rate as determined by the Calculation Agent as

52

of the applicable Series F Reset Distribution Determination Date for such Series F Reset Period. Promptly following such determination by the Calculation Agent for the Series F Preferred Units, the Calculation Agent shall notify the Partnership of the Series F Distribution Rate for such Series F Reset Period. Such Calculation Agent’s determination of any Series F Distribution Rate for each Series F Reset Period and its calculation of the amount of Series F Distributions for any Series F Reset Period will be (i) available on file at the principal offices of the Partnership beginning on or after the Series F First Call Date, (ii) made available to any Series F Holder upon request and (iii) final and binding on each Series F Holder in the absence of manifest error.

(D) The Partnership will provide notice of the relevant Series F Five-year U.S. Treasury Rate as soon as practicable to the Transfer Agent and the Series F Holders.

(E) Notwithstanding the foregoing, unless otherwise determined by the General Partner, Series F Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series F Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series F Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.22(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series F Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series F Preferred Units; provided, however, that (i) subject to Section 5.22(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.22(b)(iii)(B) and (ii) for purposes of this Section 5.22(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series F Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series F Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series F Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series F Preferred Units, voting as a class together with holders of any other Series F Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series F Parity Securities (including any additional Series F Preferred Units) if the cumulative distributions payable on Outstanding Series F Preferred Units (or any Series F Parity Securities, if the holders of such Series F Parity Securities vote as a class together with the Series F Holders pursuant to this Section 5.22(b)(iii)(C)) are in Arrears or (y) create or issue any Series F Senior Securities.

(D) For any matter described in this Section 5.22(b)(iii) in which the Series F Holders are entitled to vote as a class (whether separately or together with the holders of any Series F Parity Securities), such Series F Holders shall be entitled to one vote per Series F Preferred Unit. Any Series F Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Section 5.22(b)(iii)(B) and Section 5.22(b)(iii)(C), no vote of the Series F Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series F Preferred Units at the time Outstanding.

53

(iv) Optional Redemption; Series F Rating Event.

(A) The Partnership shall have the right (i) on the Series F First Call Date or on any subsequent Series F Reset Date or (ii) at any time within 120 calendar days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series F Rating Event, in each case, to redeem the Series F Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (ii) of this Section 5.22(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series F Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series F Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (i) of this Section 5.22(b)(iv)(A)), or 102% (in the case of a redemption described in clause (ii) of this Section 5.22(b)(iv)(A)), of the Series F Liquidation Preference for such Series F Preferred Unit on such Series F Redemption Date plus an amount equal to all unpaid Series F Distributions thereon from the date of issuance to, but excluding, the Series F Redemption Date (whether or not such distributions shall have been declared) (the “Series F Redemption Price”). So long as the Series F Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series F Redemption Price shall be paid by the Paying Agent to the Depositary on the Series F Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 30 calendar days and not more than 60 calendar days before the scheduled Series F Redemption Date to the Series F Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series F Preferred Units to be redeemed as such Series F Holders’ names appear on the books of the Transfer Agent and at the address of such Series F Holders shown therein. Such notice (the “Series F Redemption Notice”) shall state, as applicable: (1) the Series F Redemption Date, (2) the number of Series F Preferred Units to be redeemed and, if less than all Outstanding Series F Preferred Units are to be redeemed, the number (and in the case of Series F Preferred Units in certificated form, the identification) of Series F Preferred Units to be redeemed from such Series F Holder, (3) the Series F Redemption Price, (4) the place where any Series F Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series F Redemption Price therefor (which shall occur automatically if the Certificate representing such Series F Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series F Preferred Units to be redeemed shall cease to accumulate from and after such Series F Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series F Preferred Units, the number of Series F Preferred Units to be redeemed shall be determined by the General Partner, and such Series F Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series F Preferred Units. The aggregate Series F Redemption Price for any such partial redemption of the Outstanding Series F Preferred Units shall be allocated correspondingly among the redeemed Series F Preferred Units. The Series F Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.22.

(D) If the Partnership gives or causes to be given a Series F Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series F Preferred Units as to which such Series F Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series F Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series F Redemption Price to each Series F Holder whose Series F Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series F Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series F Redemption Notice. If a Series F Redemption Notice shall have been given, from and

54

after the Series F Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series F Redemption Notice, all Series F Distributions on such Series F Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series F Preferred Units as Limited Partners with respect to such Series F Preferred Units to be redeemed shall cease, except the right to receive the Series F Redemption Price, and such Series F Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series F Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series F Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series F Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series F Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Series F Redemption Notice, there shall be no redemption of any Series F Preferred Units called for redemption until funds sufficient to pay the full Series F Redemption Price of such Series F Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series F Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series F Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series F Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series F Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series F Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.22, in the event that full cumulative distributions on the Series F Preferred Units and any Series F Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series F Preferred Units or Series F Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series F Holders and holders of any Series F Parity Securities. Subject to Section 4.9, so long as any Series F Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series F Junior Securities unless full cumulative distributions on the Series F Preferred Units and any Series F Parity Securities for all prior and the then-ending Series F Distribution Periods, with respect to the Series F Preferred Units, and all prior and then ending distribution periods, with respect to any such Series F Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights.

In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series F Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series F Senior Securities or Series F Parity Securities), (i) first, any accumulated and unpaid distributions on the Series F Preferred Units (regardless of whether previously declared) and (ii) then, any positive value in each such holder’s Capital Account in respect of such Series F Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in

55

respect of such Series F Preferred Units is less than the aggregate Series F Base Liquidation Preference of such Series F Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series F Parity Securities upon which like allocation and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series F Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series F Preferred Unit is equal to the Series F Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series F Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v) and 5.23(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series F Preferred Units and such Series F Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series F Preferred Unit and such Series F Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series F Preferred Units is less than the aggregate Series F Base Liquidation Preference of such Series F Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series F Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series F Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series F Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series F Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v) and 5.23(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series F Preferred Units and such Series F Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series F Preferred Unit and such Series F Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series F Preferred Units and any Series F Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series F Preferred Units shall become entitled to receive any distributions in respect of the Series F Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series F Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series F Senior Securities or Series F Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series F Preferred Units.

56

(vi) Rank.

The Series F Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series F Junior Securities;

(B) on a parity with any Series F Parity Securities;

(C) junior to any Series F Senior Securities; and

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund.

The Series F Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders.

To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series F Holder as the true, lawful, and absolute owner of the applicable Series F Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series F Preferred Units may be listed or admitted to trading, if any.

(ix) Notices. All notices or other communications in respect of Series F Holders shall be sufficiently given (i) if given in writing and either delivered in person or by first class mail, postage prepaid, or (ii) if given in such other manner as may be permitted in this Section 5.22, the Agreement or by applicable law.

(x) Other Rights; Fiduciary Duties.

The Series F Preferred Units and the Series F Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series F Holders, other than the implied contractual covenant of good faith and fair dealing.

Section 5.23 Establishment of Series G Preferred Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “7.125% Series G Fixed-Rate Reset Cumulative Redeemable Perpetual Preferred Units” (the “Series G Preferred Units”), having the preferences, rights, powers, and duties set forth herein, including this Section 5.23. Each Series G Preferred Unit shall be identical in all respects to every other Series G Preferred Unit, except as to the respective dates from which the Series G Liquidation Preference shall increase or from which Series G Distributions may begin accruing, to the extent such dates may differ. The Series G Preferred Units represent perpetual equity interests in the Partnership and shall not give rise to a claim by the Partnership or a Series G Holder for conversion or, except as set forth in Section 5.23(b)(iv), redemption thereof at a particular date.

57

(b) Rights of Series G Preferred Units. The Series G Preferred Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Series G Preferred Units.

(A) The authorized number of Series G Preferred Units shall be unlimited. Series G Preferred Units that are purchased or otherwise acquired by the Partnership shall be cancelled.

(B) The Series G Preferred Units shall be represented by one or more global Certificates registered in the name of the Depositary or its nominee, and no Series G Holder shall be entitled to receive a definitive Certificate evidencing its Series G Preferred Units, unless (1) requested by a Series G Holder and consented to by the General Partner in its sole discretion, (2) otherwise required by law or (3) the Depositary gives notice of its intention to resign or is no longer eligible to act as such with respect to the Series G Preferred Units and the General Partner shall have not selected a substitute Depositary within 60 calendar days thereafter. So long as the Depositary shall have been appointed and is serving with respect to the Series G Preferred Units, payments and communications made by the Partnership to Series G Holders shall be made by making payments to, and communicating with, the Depositary.

(ii) Distributions.

(A) Distributions on each Outstanding Series G Preferred Unit shall be cumulative and shall accumulate at the applicable Series G Distribution Rate from and including November 16, 2020 (or, for any subsequently issued and newly Outstanding Series G Preferred Units, from and including the Series G Distribution Payment Date immediately preceding the issue date of such Series G Preferred Units) until such time as the Partnership pays the Series G Distribution or redeems such Series G Preferred Unit in accordance with Section 5.23(b)(iv), whether or not such Series G Distributions shall have been declared. Series G Holders shall be entitled to receive Series G Distributions from time to time out of any assets of the Partnership legally available for the payment of distributions at the Series G Distribution Rate per Series G Preferred Unit when, as, and, if declared by the General Partner. Series G Distributions, to the extent declared by the General Partner to be paid by the Partnership in accordance with this Section 5.23(b)(ii), shall be paid, in Arrears, on each Series G Distribution Payment Date. Series G Distributions shall accumulate in each Series G Distribution Period from and including the preceding Series G Distribution Payment Date (other than the initial Series G Distribution Period, which shall commence on and include November 16, 2020), to, but excluding, the next Series G Distribution Payment Date for such Series G Distribution Period; provided that distributions shall accrue on accumulated but unpaid Series G Distributions at the Series G Distribution Rate. If any Series G Distribution Payment Date otherwise would occur on a date that is not a Business Day, declared Series G Distributions shall be paid on the immediately succeeding Business Day without the accumulation of additional distributions. All Series G Distributions that are (1) accumulated and unpaid or (2) payable by the Partnership pursuant to this Section 5.23(b)(ii) shall be payable without regard to income of the Partnership and shall be treated for federal income tax purposes as guaranteed payments for the use of capital under Section 707(c) of the Code. The guaranteed payment with respect to any Series G Distribution Period shall be for the account of the holders of Series G Preferred Units as of the applicable Series G Distribution Record Date.

(B) Not later than 5:00 p.m., New York City time, on each Series G Distribution Payment Date, the Partnership shall pay those Series G Distributions, if any, that shall have been declared by the General Partner to Series G Holders on the Record Date for the applicable Series G Distribution. The Record Date (the “Series G Distribution Record Date”) for the payment of any Series G Distributions shall be as of the close of business on the first Business Day of the month of the applicable Series G Distribution Payment Date, except that in the case of payments of Series G Distributions in Arrears, the Series G Distribution Record Date with respect to a Series G Distribution Payment Date shall be such date as may be designated by the General Partner in

58

accordance with this Section 5.23. So long as any Series G Preferred Units are Outstanding, no distribution shall be declared or paid or set aside for payment on any Series G Junior Securities (other than a distribution payable solely in Series G Junior Securities) unless full cumulative Series G Distributions have been or contemporaneously are being paid or set apart for payment on all Outstanding Series G Preferred Units (and distributions on any other Series G Parity Securities) through the most recent respective Series G Distribution Payment Date (and distribution payment date with respect to such Series G Parity Securities, if any); provided, however, notwithstanding anything to the contrary in this Section 5.23(b)(ii)(B), if a distribution period with respect to a class of Series G Junior Securities or Series G Parity Securities is shorter than the Series G Distribution Period, the General Partner may declare and pay regular distributions with respect to such Series G Junior Securities or Series G Parity Securities, so long as, at the time of declaration of such distribution, (i) there are no Series G Distributions in Arrears, and (ii) the General Partner expects to have sufficient funds to pay the full distribution in respect of the Series G Preferred Units on the next successive Series G Distribution Payment Date. Accumulated Series G Distributions in Arrears for any past Series G Distribution Period may be declared by the General Partner and paid on any date fixed by the General Partner, whether or not a Series G Distribution Payment Date, to Series G Holders on the Record Date for such payment, which may not be less than 10 calendar days before such payment date. Subject to the next succeeding sentence, if all accumulated Series G Distributions in Arrears on all Outstanding Series G Preferred Units and all accumulated distributions in arrears on any Series G Parity Securities shall not have been declared and paid, or if sufficient funds for the payment thereof shall not have been set apart, payment of accumulated distributions in Arrears on the Series G Preferred Units and accumulated distributions in arrears on any such Series G Parity Securities shall be made in order of their respective distribution payment dates, commencing with the earliest distribution payment date. If less than all distributions payable with respect to all Series G Preferred Units and any other Series G Parity Securities are paid, any partial payment shall be made Pro Rata with respect to the Series G Preferred Units and any such other Series G Parity Securities entitled to a distribution payment at such time in proportion to the aggregate distribution amounts remaining due in respect of such Series G Preferred Units and such other Series G Parity Securities at such time. Subject to Section 12.4 and Section 5.23(b)(v), Series G Holders shall not be entitled to any distribution, whether payable in cash, property or Partnership Securities, in excess of full cumulative Series G Distributions. Except insofar as distributions accrue on the amount of any accumulated and unpaid Series G Distributions as described in Section 5.23(b)(ii)(A), no interest or sum of money in lieu of interest shall be payable in respect of any distribution payment which may be in Arrears on the Series G Preferred Units. So long as the Series G Preferred Units are held of record by the Depositary or its nominee, declared Series G Distributions shall be paid to the Depositary in same-day funds on each Series G Distribution Payment Date or other distribution payment date in the case of payments for Series G Distributions in Arrears.

(C) The Series G Distribution Rate for each Series G Reset Period will be determined by the Calculation Agent for the Series G Preferred Units using the Series G Five-year U.S. Treasury Rate, as of the applicable Series G Reset Distribution Determination Date for such Series G Reset Period. The Calculation Agent for the Series G Preferred Units then will add the spread of 5.306% per annum to the Series G Five-year U.S. Treasury Rate as determined by the Calculation Agent as of the applicable Series G Reset Distribution Determination Date for such Series G Reset Period. Promptly following such determination by the Calculation Agent for the Series G Preferred Units, the Calculation Agent shall notify the Partnership of the Series G Distribution Rate for such Series G Reset Period. Such Calculation Agent’s determination of any Series G Distribution Rate for each Series G Reset Period and its calculation of the amount of Series G Distributions for any Series G Reset Period will be (i) available on file at the principal offices of the Partnership beginning on or after the Series G First Call Date, (ii) made available to any Series

59

G Holder upon request and (iii) final and binding on each Series G Holder in the absence of manifest error.

(D) The Partnership will provide notice of the relevant Series G Five-year U.S. Treasury Rate as soon as practicable to the Transfer Agent and the Series G Holders.

(E) Notwithstanding the foregoing, unless otherwise determined by the General Partner, Series G Distributions shall be deemed to have been paid out of deductions from Available Cash with respect to the Quarter ended immediately preceding the Quarter in which the Series G Distribution is made.

(iii) Voting Rights.

(A) Notwithstanding anything to the contrary in this Agreement, the Series G Preferred Units shall not have any voting rights or rights to consent or approve any action or matter, except as set forth in Section 13.3(c), this Section 5.23(b)(iii) or as otherwise required by the Delaware Act.

(B) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series G Preferred Units, voting as a separate class, the General Partner shall not adopt any amendment to this Agreement that the General Partner determines would have a material adverse effect on the powers, preferences, duties, or special rights of the Series G Preferred Units; provided, however, that (i) subject to Section 5.23(b)(iii)(C), the issuance of additional Partnership Securities (and any amendment to this Agreement in connection therewith) shall not be deemed to constitute such a material adverse effect for purposes of this Section 5.23(b)(iii)(B) and (ii) for purposes of this Section 5.23(b)(iii)(B), no amendment of this Agreement in connection with a merger or other transaction in which the Series G Preferred Units remain Outstanding with the terms thereof materially unchanged in any respect adverse to the Series G Holders (as determined by the General Partner) shall be deemed to materially and adversely affect the powers, preferences, duties, or special rights of the Series G Preferred Units.

(C) Notwithstanding anything to the contrary in this Agreement, without the affirmative vote or consent of the holders of at least 66 2/3% of the Outstanding Series G Preferred Units, voting as a class together with holders of any other Series G Parity Securities upon which like voting rights have been conferred and are exercisable, the Partnership shall not (x) create or issue any Series G Parity Securities (including any additional Series G Preferred Units) if the cumulative distributions payable on Outstanding Series G Preferred Units (or any Series G Parity Securities, if the holders of such Series G Parity Securities vote as a class together with the Series G Holders pursuant to this Section 5.23(b)(iii)(C)) are in Arrears or (y) create or issue any Series G Senior Securities.

(D) For any matter described in this Section 5.23(b)(iii) in which the Series G Holders are entitled to vote as a class (whether separately or together with the holders of any Series G Parity Securities), such Series G Holders shall be entitled to one vote per Series G Preferred Unit. Any Series G Preferred Units held by the Partnership or any of its Subsidiaries or their controlled Affiliates shall not be entitled to vote.

(E) Notwithstanding Section 5.23(b)(iii)(B) and Section 5.23(b)(iii)(C), no vote of the Series G Holders shall be required if, at or prior to the time when such action is to take effect, provision is made for the redemption of all Series G Preferred Units at the time Outstanding.

(iv) Optional Redemption; Series G Rating Event.

(A) The Partnership shall have the right (i) on the Series G First Call Date or on any subsequent Series G Reset Date or (ii) at any time within 120 calendar days after the conclusion of any review or appeal process instituted by the Partnership following the occurrence of a Series G Rating Event, in each case, to redeem the Series G Preferred Units, which redemption may be in whole or in part (except with respect to a redemption pursuant to clause (ii) of this

60

Section 5.23(b)(iv)(A) which shall be in whole but not in part), using any source of funds legally available for such purpose. Any such redemption shall occur on a date set by the General Partner (the “Series G Redemption Date”). The Partnership shall effect any such redemption by paying cash for each Series G Preferred Unit to be redeemed equal to 100% (in the case of a redemption described in clause (i) of this Section 5.23(b)(iv)(A)), or 102% (in the case of a redemption described in clause (ii) of this Section 5.23(b)(iv)(A)), of the Series G Liquidation Preference for such Series G Preferred Unit on such Series G Redemption Date plus an amount equal to all unpaid Series G Distributions thereon from the date of issuance to, but excluding, the Series G Redemption Date (whether or not such distributions shall have been declared) (the “Series G Redemption Price”). So long as the Series G Preferred Units to be redeemed are held of record by the Depositary or the nominee of the Depositary, the Series G Redemption Price shall be paid by the Paying Agent to the Depositary on the Series G Redemption Date.

(B) The Partnership shall give notice of any redemption by mail, postage prepaid, not less than 30 calendar days and not more than 60 calendar days before the scheduled Series G Redemption Date to the Series G Holders (as of 5:00 p.m. New York City time on the Business Day next preceding the day on which notice is given) of any Series G Preferred Units to be redeemed as such Series G Holders’ names appear on the books of the Transfer Agent and at the address of such Series G Holders shown therein. Such notice (the “Series G Redemption Notice”) shall state, as applicable: (1) the Series G Redemption Date, (2) the number of Series G Preferred Units to be redeemed and, if less than all Outstanding Series G Preferred Units are to be redeemed, the number (and in the case of Series G Preferred Units in certificated form, the identification) of Series G Preferred Units to be redeemed from such Series G Holder, (3) the Series G Redemption Price, (4) the place where any Series G Preferred Units in certificated form are to be redeemed and shall be presented and surrendered for payment of the Series G Redemption Price therefor (which shall occur automatically if the Certificate representing such Series G Preferred Units is issued in the name of the Depositary or its nominee), and (5) that distributions on the Series G Preferred Units to be redeemed shall cease to accumulate from and after such Series G Redemption Date.

(C) If the Partnership elects to redeem less than all of the Outstanding Series G Preferred Units, the number of Series G Preferred Units to be redeemed shall be determined by the General Partner, and such Series G Preferred Units shall be redeemed by such method of selection as the Depositary shall determine, either Pro Rata or by lot, with adjustments to avoid redemption of fractional Series G Preferred Units. The aggregate Series G Redemption Price for any such partial redemption of the Outstanding Series G Preferred Units shall be allocated correspondingly among the redeemed Series G Preferred Units. The Series G Preferred Units not redeemed shall remain Outstanding and entitled to all the rights, preferences and duties provided in this Section 5.23.

(D) If the Partnership gives or causes to be given a Series G Redemption Notice, the Partnership shall deposit with the Paying Agent funds sufficient to redeem the Series G Preferred Units as to which such Series G Redemption Notice shall have been given, no later than 10:00 a.m. New York City time on the Series G Redemption Date, and shall give the Paying Agent irrevocable instructions and authority to pay the Series G Redemption Price to each Series G Holder whose Series G Preferred Units are to be redeemed upon surrender or deemed surrender (which shall occur automatically if the Certificate representing such Series G Preferred Units is issued in the name of the Depositary or its nominee) of the Certificates therefor as set forth in the Series G Redemption Notice. If a Series G Redemption Notice shall have been given, from and after the Series G Redemption Date, unless the Partnership defaults in providing funds sufficient for such redemption at the time and place specified for payment pursuant to the Series G Redemption Notice, all Series G Distributions on such Series G Preferred Units to be redeemed shall cease to accumulate and all rights of holders of such Series G Preferred Units as Limited Partners with respect to such Series G Preferred Units to be redeemed shall cease, except the right

61

to receive the Series G Redemption Price, and such Series G Preferred Units shall not thereafter be transferred on the books of the Transfer Agent or be deemed to be Outstanding for any purpose whatsoever. The Series G Holders shall have no claim to the interest income, if any, earned on funds deposited with the Paying Agent. Any funds deposited with the Paying Agent hereunder by the Partnership for any reason, including redemption of Series G Preferred Units, that remain unclaimed or unpaid after one year after the applicable Series G Redemption Date or other payment date, as applicable, shall be, to the extent permitted by law, repaid to the Partnership upon its written request, after which repayment the Series G Holders entitled to such redemption or other payment shall have recourse only to the Partnership. Notwithstanding any Series G Redemption Notice, there shall be no redemption of any Series G Preferred Units called for redemption until funds sufficient to pay the full Series G Redemption Price of such Series G Preferred Units shall have been deposited by the Partnership with the Paying Agent.

(E) Any Series G Preferred Units that are redeemed or otherwise acquired by the Partnership shall be cancelled. If only a portion of the Series G Preferred Units represented by a Certificate shall have been called for redemption, upon surrender of the Certificate to the Paying Agent (which shall occur automatically if the Certificate representing such Series G Preferred Units is registered in the name of the Depositary or its nominee), the Partnership shall issue and the Paying Agent shall deliver to the Series G Holders a new Certificate (or adjust the applicable book-entry account) representing the number of Series G Preferred Units represented by the surrendered Certificate that have not been called for redemption.

(F) Notwithstanding anything to the contrary in this Section 5.23, in the event that full cumulative distributions on the Series G Preferred Units and any Series G Parity Securities shall not have been paid or declared and set aside for payment, the Partnership shall not be permitted to repurchase, redeem or otherwise acquire, in whole or in part, any Series G Preferred Units or Series G Parity Securities except pursuant to a purchase or exchange offer made on the same relative terms to all Series G Holders and holders of any Series G Parity Securities. Subject to Section 4.9, so long as any Series G Preferred Units are Outstanding, the Partnership shall not be permitted to redeem, repurchase or otherwise acquire any Common Units or any other Series G Junior Securities unless full cumulative distributions on the Series G Preferred Units and any Series G Parity Securities for all prior and the then-ending Series G Distribution Periods, with respect to the Series G Preferred Units, and all prior and then ending distribution periods, with respect to any such Series G Parity Securities, shall have been paid or declared and set aside for payment.

(v) Liquidation Rights.

In the event of the dissolution and winding up of the Partnership under Section 12.4 or a sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, either voluntary or involuntary, the Record Holders of the Series G Preferred Units shall be entitled to receive, out of the assets of the Partnership available for distribution to the Partners or any Assignees, prior and in preference to any distribution of any assets of the Partnership to the Record Holders of any other class or series of Partnership Interests (other than Series G Senior Securities or Series G Parity Securities), (i) first, any accumulated and unpaid distributions on the Series G Preferred Units (regardless of whether previously declared) and (ii) then, any positive value in each such holder’s Capital Account in respect of such Series G Preferred Units. If in the year of such dissolution and winding up, or sale, exchange, or other disposition of all or substantially all of the assets of the Partnership, any such Record Holder’s Capital Account in respect of such Series G Preferred Units is less than the aggregate Series G Base Liquidation Preference of such Series G Preferred Units, then, notwithstanding anything to the contrary contained in this Agreement, and prior to any other allocation pursuant to this Agreement for such year and any distribution pursuant to the preceding sentence (other than any allocations or distributions made with respect to any other Series G Parity Securities upon which like allocation

62

and distribution rights have been conferred), items of gross income and gain shall be allocated to all Unitholders then holding Series G Preferred Units, Pro Rata, until the Capital Account in respect of each Outstanding Series G Preferred Unit is equal to the Series G Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event that like allocation rights have been conferred upon other Series G Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v) and 5.22(b)(v)), then items of gross income and gain shall be allocated to all Unitholders then holding Series G Preferred Units and such Series G Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series G Preferred Unit and such Series G Parity Security is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). If in the year of such dissolution and winding up any such Record Holder’s Capital Account in respect of such Series G Preferred Units is less than the aggregate Series G Base Liquidation Preference of such Series G Preferred Units after the application of the preceding sentence, then to the extent permitted by applicable law, but otherwise notwithstanding anything to the contrary contained in this Agreement, items of gross income and gain for any preceding taxable year(s) with respect to which IRS Form 1065 Schedules K-1 have not been filed by the Partnership shall be reallocated to all Unitholders then holding Series G Preferred Units, Pro Rata, until the Capital Account in respect of each such Outstanding Series G Preferred Unit after making allocations pursuant to this and the immediately preceding sentence is equal to the Series G Base Liquidation Preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation); provided, however, that in the event like allocation rights have been conferred upon other Series G Parity Securities (including pursuant to Sections 5.17(b)(v), 5.18(b)(v), 5.19(b)(v), 5.20(b)(v), 5.21(b)(v) and 5.22(b)(v)), then any such items of gross income and gain shall be reallocated to all Unitholders then holding Series G Preferred Units and such Series G Parity Securities, Pro Rata, until the Capital Account in respect of each Outstanding Series G Preferred Unit and such Series G Parity Security after making allocations pursuant to this and the immediately preceding sentence is equal to the applicable liquidation preference (and no other allocation pursuant to this Agreement shall reverse the effect of such allocation). After such allocations have been made to the Outstanding Series G Preferred Units and any Series G Parity Securities, as applicable, any remaining Net Termination Gain or Net Termination Loss shall be allocated to the Partners pursuant to Section 6.1(c) or Section 6.1(d), as the case may be. At the time of the dissolution of the Partnership, subject to Section 17-804 of the Delaware Act, the Record Holders of the Series G Preferred Units shall become entitled to receive any distributions in respect of the Series G Preferred Units that are accrued and unpaid as of the date of such distribution, and shall have the status of, and shall be entitled to all remedies available to, a creditor of the Partnership, and such entitlement of the Record Holders of the Series G Preferred Units to such accrued and unpaid distributions shall have priority over any entitlement of any other Partners or Assignees (other than holders of any Series G Senior Securities or Series G Parity Securities) with respect to any distributions by the Partnership to such other Partners or Assignees; provided, however, that the General Partner, as such, will have no liability for any obligations with respect to such distributions to any Record Holder(s) of Series G Preferred Units.

(vi) Rank.

The Series G Preferred Units shall each be deemed to rank as to distributions on such Partnership Securities and distributions upon liquidation of the Partnership:

(A) senior to any Series G Junior Securities;

(B) on a parity with any Series G Parity Securities;

(C) junior to any Series G Senior Securities; and

63

(D) junior to all existing and future indebtedness of the Partnership and other liabilities with respect to assets available to satisfy claims against the Partnership.

(vii) No Sinking Fund.

The Series G Preferred Units shall not have the benefit of any sinking fund.

(viii) Record Holders.

To the fullest extent permitted by applicable law, the General Partner, the Partnership, the Transfer Agent, and the Paying Agent may deem and treat any Series G Holder as the true, lawful, and absolute owner of the applicable Series G Preferred Units for all purposes, and none of the General Partner, the Partnership, the Transfer Agent or the Paying Agent shall be affected by any notice to the contrary, except as otherwise provided by law or any applicable rule, regulation, guideline or requirement of any National Securities Exchange on which the Series G Preferred Units may be listed or admitted to trading, if any.

(ix) Notices. All notices or other communications in respect of Series G Holders shall be sufficiently given (i) if given in writing and either delivered in person or by first class mail, postage prepaid, or (ii) if given in such other manner as may be permitted in this Section 5.23, the Agreement or by applicable law.

(x) Other Rights; Fiduciary Duties.

The Series G Preferred Units and the Series G Holders shall not have any designations, preferences, rights, powers or duties, other than as set forth in this Agreement or as provided by applicable law. Notwithstanding anything to the contrary in this Agreement or any duty existing at law, in equity or otherwise, to the fullest extent permitted by applicable law, neither the General Partner nor any other Indemnitee shall owe any duties, including fiduciary duties, or have any liabilities to Series G Holders, other than the implied contractual covenant of good faith and fair dealing.”

Section 5.24 Establishment of Class B Units.

(a) General. The Partnership hereby designates and creates a class of Partnership Securities to be designated as “Class B Units” (the “Class B Units”), having the preferences, rights, powers and duties set forth herein, including this Section 5.24. In accordance with Section 5.8, the General Partner shall have the power and authority to issue additional Class B Units in the future.

(b) Rights of Class B Units. The Class B Units shall have the following rights, preferences and privileges and shall be subject to the following duties and obligations:

(i) Initial Capital Account. The initial Capital Account with respect to each Class B Unit will be equal to the Class B Unit Issue Price. For the avoidance of doubt, the sum of the initial Capital Accounts with respect to each Class B Unit as of the Effective Date is equal to the sum of the Capital Accounts of each Recapitalized Unit issued to ETP Holdco as of the Effective Date.

(ii) Allocations.

(A) The holders of Class B Units shall not be entitled to receive (1) any allocations of ETP Holdco Items, and (2) except as otherwise provided in this Section 5.24(b)(ii), allocations of (a) Net Income pursuant to Section 6.1(a), (b) Net Loss pursuant to Section 6.1(b), or (c) Net Termination Gains and Losses pursuant to Section 6.1(c).

(B) With respect to each taxable period, the holders of the Class B Units shall be allocated, Pro Rata in proportion to the number of Class B Units of the holders, items of Partnership gross income, gain, loss or deduction (other than from ETP Holdco Items and items of Partnership depreciation, amortization and cost recovery deductions) until the aggregate amount of such items allocated to the holders of the Class B Units pursuant to this Section 5.24(b)(ii)(B) for the current

64

taxable period and all previous taxable periods is equal to the cumulative amount of all distributions made to the holders of the Class B Units pursuant to Section 5.24(b)(iii).

(C) Items of Partnership depreciation, amortization and cost recovery deductions (other than from ETP Holdco Items) with respect to each taxable period shall be allocated to the holders of Class B Units to the extent such items would be allocated to the holders of Class B Units as if each Class B Unit was treated as a Common Unit.

(D) With respect to each taxable period, after the application of Section 6.1(c)(i)(B) but before the application of Section 6.1(c)(i)(C), Net Termination Gain (other than from ETP Holdco Items) shall be allocated to the holders of the Class B Units, until the Capital Account of each Class B Unit is equal to the Class B Unit Issue Price.

(E) For each taxable period, after the application of Section 6.1(c)(i)(B) but before the application of Section 6.1(c)(i)(C), and after making the allocations provided for in Section 5.24(b)(ii)(D), the holder of the Class B Units shall be allocated, 1% of the remaining aggregate Net Termination Gain (other than from ETP Holdco Items), if any, that is to be allocated pursuant to Section 6.1(c)(i)(C); provided, however, that an allocation shall only be made to the holder of Class B Units pursuant to this Section 5.24(b)(ii)(E) if the Capital Account of each Common Unit is equal to or greater than the Class B Unit Issue Price immediately prior to making such allocation.

(F) For each taxable period, after the application of Section 6.1(c)(ii)(B), but before the application of Section 6.1(c)(ii)(C), the holders of the Class B Units shall be allocated Net Termination Loss (other than from ETP Holdco Items) until the Capital Account in respect of each Class B Unit has been reduced to zero.

(G) For the purposes of effectuating the intent of the foregoing allocation provisions, the General Partner shall have the sole discretion to make special allocations of items of Partnership gross income, gain, loss or deductions among the General Partner and the Unitholders as it deems reasonable.

(iii) Distributions.

(A) For each taxable period, no portion of any Partnership cash distribution attributable to ETP Holdco Distributions shall be distributed to the holders of the Class B Units.

(B) Commencing with the Class B Unit Issuance Date, the holder of the Class B Units as of an applicable Record Date shall be entitled to receive distributions (each, a “Class B Unit Quarterly Distribution”) in cash in an amount equal to the Class B Unit Distribution Rate on all Outstanding Class B Units. Distributions shall be paid Quarterly, in arrears, within 50 days after the end of each Quarter. Each Record Date established for paying a Class B Unit Quarterly Distribution in respect of any Quarter shall be the same Record Date established for any distribution to be made by the Partnership in respect of other Partnership Interests pursuant to Section 6.3. If the Partnership is unable to pay the Class B Unit Quarterly Distribution with respect to any Quarter, (1) the amount of such accrued and unpaid distributions will accumulate until paid in full in cash and (2) the balance of such accrued and unpaid distributions shall increase at a rate of 1.5% per annum, compounded quarterly, from the date such distribution was due until the date it is paid. For the avoidance of doubt, except as set forth in this Section 5.24(b)(iii)(B) or Article XII, the Class B Units will not be entitled to receive any distributions.

(iv) Voting Rights. Except as set forth in this Section 5.24(b)(iv) and Section 13.3(c) and except to the extent the Delaware Act gives the Class B Units a vote as a class on any matter, the Class B Units shall not have any voting rights. With respect to any matter on which the Class B Units are entitled to vote, each Class B Unit will be entitled to one vote on such matter. The General Partner shall not, without the affirmative vote or written consent of holders of a majority of the Class B Units then Outstanding, amend, alter, modify or change this Section 5.24 (or vote or consent or resolve to take such action).

65

(v) Redemption and Conversion Rights. The Class B Units will be perpetual and shall not have any rights of redemption or conversion.

(vi) Certificates; Book-Entry. Unless the General Partner shall determine otherwise, the Class B Units shall not be evidenced by Certificates. Any Certificates relating to the Class B Units that may be issued will be in such form as the General Partner may approve. The Class B Units, subject to the satisfaction of any applicable legal, regulatory and contractual requirements, may be assigned or transferred in a manner identical to the assignment and transfer of other Units.

(vii) Registrar and Transfer Agent. Unless and until the General Partner determines to assign the responsibility to another Person, the General Partner will act as the registrar and transfer agent for the Class B Units.”

(d) Section 6.1(a) of the Partnership Agreement is hereby amended and restated in its entirety as follows:

“(a) Net Income. After giving effect to the special allocations set forth in Section 6.1(d) and as otherwise provided in Article V, Net Income for each taxable year and all items of income, gain, loss and deduction taken into account in computing Net Income for such taxable year shall be allocated as follows:

(i) First, 100% to the General Partner until the aggregate Net Income allocated to the General Partner pursuant to this Section 6.1(a)(i) for the current taxable year and all previous taxable years is equal to the aggregate Net Losses allocated to the General Partner pursuant to Section 6.1(b)(iv) for all previous taxable years;

(ii) Second, to all Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders, in proportion to, and to the extent of the Net Loss allocated to such Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders pursuant to Section 6.1(b)(iii) for all previous taxable years, until the aggregate amount of Net Income allocated to such Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders pursuant to this Section 6.1(a)(ii) for the current and all previous taxable years is equal to the aggregate amount of Net Loss allocated to such Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders pursuant to Section 6.1(b)(iii) for all previous taxable years; provided that in no event shall Net Income be allocated to any such Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders to cause its Capital Account in respect of a Series A Preferred Unit, a Series B Preferred Unit, a Series C Preferred Unit, a Series D Preferred Unit, a Series E Preferred Unit, a Series F Preferred Unit or a Series G Preferred Unit to exceed the Series A Base Liquidation Preference, the Series B Base Liquidation Preference, the Series C Base Liquidation Preference, the Series D Base Liquidation Preference, the Series E Base Liquidation Preference, the Series F Base Liquidation Preference or the Series G Base Liquidation Preference in respect of such Series A Preferred Units, Series B Preferred Units, Series C Preferred Units, Series D Preferred Units, Series E Preferred Units, Series F Preferred Units or Series G Preferred Units;

(iii) Third, 100% to the Unitholders (other than Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders), in accordance with their respective Percentage Interests, until the aggregate Net Income allocated to such Unitholders pursuant to this Section 6.1(a)(iii) for the current taxable year and all previous taxable years is equal to the aggregate Net Losses allocated to such Unitholders pursuant to Section 6.1(b)(ii) for all previous taxable years; and

(iv) Fourth, the balance, if any, 100% to the Unitholders in accordance with their respective Percentage Interests.”

66

(e) Section 6.1(b) of the Partnership Agreement is hereby amended and restated as follows:

“(b) Net Losses. After giving effect to the special allocations set forth in Section 6.1(d) and as otherwise provided in Article V, Net Losses for each taxable year and all items of income, gain, loss and deduction taken into account in computing Net Losses for such taxable year shall be allocated as follows:

(i) First, 100% to the Unitholders, in accordance with their respective Percentage Interests, until the aggregate Net Losses allocated pursuant to this Section 6.1(b)(i) for the current taxable year and all previous taxable years is equal to the aggregate Net Income allocated to such Unitholders pursuant to Section 6.1(a)(iv) for all previous taxable years, provided that the Net Losses shall not be allocated pursuant to this Section 6.1(b)(i) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account);

(ii) Second, 100% to the Unitholders (other than Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders) in accordance with their respective Percentage Interests; provided, that Net Losses shall not be allocated pursuant to this Section 6.1(b)(ii) to the extent that such allocation would cause any Unitholder to have a deficit balance in its Adjusted Capital Account at the end of such taxable year (or increase any existing deficit balance in its Adjusted Capital Account);

(iii) Third, to all Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders, in proportion to their respective positive Adjusted Capital Account balances, until the Adjusted Capital Account in respect of each Series A Preferred Unit, Series B Preferred Unit, Series C Preferred Unit, Series D Preferred Unit, Series E Preferred Unit, Series F Preferred Unit and Series G Preferred Unit then Outstanding has been reduced to zero; and

(iv) Fourth, the balance, if any, 100% to the General Partner.”

(f) Section 6.1(c) of the Partnership Agreement is hereby amended and restated as follows:

“(c) Net Termination Gains and Losses. After giving effect to the special allocations set forth in Section 6.1(d) and as otherwise provided in Article V, all items of income, gain, loss and deduction taken into account in computing Net Termination Gain or Net Termination Loss for such taxable year shall be allocated in the same manner as such Net Termination Gain or Net Termination Loss is allocated hereunder. All allocations under this Section 6.1(c) shall be made after Capital Account balances have been adjusted by all other allocations provided under this Section 6.1 and after all distributions pursuant to Section 6.3; provided, however, that solely for purposes of this Section 6.1(c), Capital Accounts shall not be adjusted for distributions made pursuant to Section 12.4.

(i) If a Net Termination Gain is recognized (or deemed recognized pursuant to Section 5.4(d)) such Net Termination Gain shall be allocated among the Partners in the following manner (and the Capital Accounts of the Partners shall be increased by the amount so allocated in each of the following subclauses, in the order listed, before an allocation is made pursuant to the next succeeding subclause):

(A) First, to each Unitholder having a deficit balance in its Capital Account, in the proportion that such deficit balance bears to the total deficit balances in the Capital Accounts of all Partners, until each such Partner has been allocated Net Termination Gain equal to any such deficit balance in its Capital Account;

(B) Second, to all Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders, Pro Rata, until the Capital Account in respect of each Outstanding Series A Preferred Unit, Series B Preferred Unit, Series C Preferred Unit, Series D Preferred Unit, Series E Preferred Unit, Series F Preferred Unit and Series G Preferred Unit equals the Series A Base Liquidation Preference, the Series B Base Liquidation Preference, the Series C Base Liquidation Preference, the Series D Base Liquidation Preference,

(B) Second, to all Series A Holders, Series B Holders, Series C Holders, Series D Holders, Series E Holders, Series F Holders and Series G Holders, in proportion to their Adjusted Capital Account balances, until the Adjusted Capital Account in respect of each Series A Preferred Unit, Series B Preferred Unit, Series C Preferred Unit, Series D Preferred Unit, Series E Preferred Unit, Series F Preferred Unit or Series G Preferred Unit then Outstanding has been reduced to zero; and

(C) Third, the balance, if any, 100% to the General Partner.”

“(xviii) ETP Holdco Allocations.

(A) The Class B Units shall not be entitled to receive any allocation of any ETP Holdco Items, and such ETP Holdco Items (which shall not be included in the computation of Net Income, Net Loss, Net Termination Gain or Net Termination Loss for any taxable year while any Class B Units remain Outstanding) shall instead be specifically allocated to the Unitholders (other than the holders of Class B Units), Pro Rata.

(B) For the purposes of effectuating the intent of Section 6.1(d)(xi), the General Partner may make special allocations of items of Partnership gross income, gain, loss or deductions among the Unitholders as it deems reasonable.”
