protected purchaser in whose hands such Debt Securities are valid obligations of the Partnership; 
 provided, however, that in determining whether the
Holders of the requisite principal amount of the Outstanding Debt Securities of any series have given any request, demand, authorization, direction, notice, consent or waiver hereunder, Debt Securities owned by the Partnership or any other obligor
upon the Debt Securities or any Affiliate of the Partnership or of such other obligor shall be disregarded and deemed not to be Outstanding, except that, in determining whether the Trustee shall be protected in relying upon any such request, demand,
authorization, direction, notice, consent or waiver, only Debt Securities which a Trust Officer actually knows to be so owned shall be so disregarded. Debt Securities so owned which have been pledged in good faith may be regarded as Outstanding if
the pledgee establishes to the satisfaction of the Trustee the pledgee’s right so to act with respect to such Debt Securities and that the pledgee is not the Partnership or any other obligor upon the Debt Securities or an Affiliate of the
Partnership or of such other obligor. In determining whether the Holders of the requisite principal amount of

nature, as applicable.

Section 2.04 Execution of Debt Securities. The Debt Securities shall be signed on behalf of the Partnership by at least one of the
Officers of the General Partnership. Such signatures upon the Debt Securities may be the manual or facsimile signatures of the present or any future such authorized officers and may be imprinted or otherwise reproduced on the Debt Securities. 

Only such Debt Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed
manually by the Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Debt Security executed on behalf of the Partnership by an Officer shall be conclusive
evidence that the Debt Security so authenticated has been duly authenticated and delivered hereunder. 

  
 - 10 - 








 In case any Officer of the General Partner who shall have signed any of the Debt Securities shall
cease to be such Officer before the Debt Securities so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Partnership, such Debt Securities nevertheless may be authenticated and delivered or disposed of as
though the Person who signed such Debt Securities had not ceased to be such Officer; and any Debt Security may be signed on behalf of the Partnership by such Persons as, at the actual date of the execution of such Debt Security, shall be the proper
Officers of the Partnership, although at the date of such Debt Security or of the execution of this Indenture any such Person was not such Officer. 

Section 2.05 Authentication and Delivery of Debt Securities. At any time and from time to time after the execution and delivery of
this Indenture, the Partnership may deliver to the Trustee for authentication Debt Securities of any series executed by the Partnership, and the Trustee shall thereupon authenticate and deliver said Debt Securities to or upon a Partnership Order. In
authenticating such Debt Securities, and accepting the additional responsibilities under this Indenture in relation to such Debt Securities, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be fully protected in
relying upon: 
 (a) a copy of any resolution or resolutions of the Board of Directors, certified by the Secretary or Assistant Secretary of
the General Partner, authorizing the terms of issuance of any series of Debt Securities; 
 (b) an executed supplemental Indenture, if any;

 (c) an Officer’s Certificate; and 

(d) an Opinion of Counsel prepared in accordance with Section 13.05 stating to the effect that: 

(i) that the form of such Debt Securities has been established by or pursuant to a resolution of the Board of Directors or by a
supplemental Indenture in conformity with the provisions of this Indenture; and 
 (ii) that such Debt Securities, when
authenticated and delivered by the Trustee and issued by the Partnership in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Partnership, enforceable in
accordance with their terms except as the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally and rights of acceleration and the availability of equitable
remedies may be limited by equitable principles of general applicability. 
 Such Opinion of Counsel need express no opinion as to whether a
court in the United States would render a money judgment in a currency other than that of the United States. 
 The Trustee shall have the
right to decline to authenticate and deliver any Debt Securities under this Section 2.05 if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors
or trustees, executive committee or a trust committee of directors, trustees or Trust Officers (or any combination thereof) shall determine that such action would expose the Trustee, in its sole discretion, to personal liability to existing Holders.


  
 - 11 - 








 The Trustee may appoint an authenticating agent reasonably acceptable to the Partnership to
authenticate Debt Securities of any series. Unless limited by the terms of such appointment, an authenticating agent may authenticate Debt Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee
includes authentication by such agent. An authenticating agent has the same rights as any Registrar, paying agent or agent for service of notices and demands. 

Unless otherwise provided in the form of Debt Security for any series, each Debt Security shall be dated the date of its authentication. 

Section 2.06 Denomination of Debt Securities. Unless otherwise provided in the form of Debt Security for any series, the Debt
Securities of each series shall be issuable only as fully registered Debt Securities in such Dollar denominations as shall be specified or contemplated by Section 2.03. In the absence of any such specification with respect to the Debt
Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any integral multiple thereof. 

Section 2.07 Registration of Transfer and Exchange. 

(a) The Partnership shall keep or cause to be kept a register for each series of Debt Securities issued hereunder (hereinafter collectively
referred to as the “Debt Security Register”), in which, subject to such reasonable regulations as it may prescribe, the Partnership shall provide for the registration of all Debt Securities and the transfer of Debt Securities as in this
Article II provided. At all reasonable times the Debt Security Register shall be open for inspection by the Trustee. Subject to Section 2.15, upon due presentment for registration of transfer of any Debt Security at any office or agency to be
maintained by the Partnership in accordance with the provisions of Section 4.02, the Partnership shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Debt Security or Debt Securities of
authorized denominations for a like aggregate principal amount. In no event may Debt Securities be issued as, or exchanged for, bearer securities. 

Unless and until otherwise determined by the Partnership, the Debt Security Register shall be kept at the Corporate Trust Office of the
Trustee and, for this purpose, the Trustee shall be designated “Registrar.” 
 Debt Securities of any series (other than a Global
Security, except as set forth below) may be exchanged for a like aggregate principal amount of Debt Securities of the same series of other authorized denominations. Subject to Section 2.15, Debt Securities to be exchanged shall be surrendered
at the office or agency to be maintained by the Partnership as provided in Section 4.02, and the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor the Debt Security or Debt Securities which the Holder
making the exchange shall be entitled to receive. 
 (b) All Debt Securities presented or surrendered for registration of transfer, exchange
or payment shall (if so required by the Partnership, the Trustee or the Registrar) be duly endorsed 

  
 - 12 - 








 
or be accompanied by a written instrument or instruments of transfer, in form satisfactory to the Partnership, the Trustee and the Registrar, duly executed by the Holder or his attorney duly
authorized in writing. 
 All Debt Securities issued in exchange for or upon transfer of Debt Securities shall be the valid obligations of
the Partnership, evidencing the same debt, and entitled to the same benefits under this Indenture as the Debt Securities surrendered for such exchange or transfer. 

No service charge shall be made for any exchange or registration of transfer of Debt Securities (except as provided by Section 2.09), but
the Partnership may require payment of a sum sufficient to cover any tax, fee, assessment or other governmental charge that may be imposed in relation thereto, other than those expressly provided in this Indenture to be made at the
Partnership’s own expense or without expense or without charge to the Holders. 
 The Partnership shall not be required (i) to
issue, register the transfer of or exchange any Debt Securities for a period of 15 days next preceding any mailing of notice of redemption of Debt Securities of such series or (ii) to register the transfer of or exchange any Debt Securities
selected, called or being called for redemption. 
 Prior to the due presentation for registration of transfer of any Debt Security, the
Partnership, the Trustee, any paying agent or any Registrar may deem and treat the Person in whose name a Debt Security is registered as the absolute owner of such Debt Security for the purpose of receiving payment of or on account of the principal
of, and premium, if any, and (subject to Section 2.12) interest on, such Debt Security and for all other purposes whatsoever, whether or not such Debt Security is overdue, and none of the Partnership, the Trustee, any paying agent or any
Registrar shall be affected by notice to the contrary. 
 None of the Partnership, the Trustee, any agent of the Trustee, any paying agent
or any Registrar will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interests. 
 None of the Partnership, the Trustee, any agent of the Trustee, any paying agent or any
Registrar will have any responsibility or obligation to any beneficial owner in a Global Security, an agent member or participant or other Person with respect to the accuracy of the records of the Depositary or its nominee or of any agent member,
with respect to any ownership interest in the Debt Securities or with respect to the delivery to any agent member, beneficial owner or other Person (other than the Depositary) of any notice (including any notice of redemption) or the payment of any
amount, under or with respect to such Debt Securities. All notices and communications to be given to the Holders and all payments to be made to Holders under the Debt Securities and this Indenture shall be given or made only to or upon the order of
the registered holders (which shall be the Depositary or its nominee in the case of the Global Security). The rights of beneficial owners in the Global Security shall be exercised only through the Depositary subject to the applicable procedures. The
Trustee, any paying agent and any Registrar shall be entitled to rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners. The Trustee, any paying
agent and any Registrar shall be entitled to deal with the Depositary, 

  
 - 13 - 








 
and any nominee thereof, that is the registered holder of any Global Security for all purposes of this Indenture relating to such Global Security (including the payment of principal, premium, if
any, and interest and additional amounts, if any, and the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global Security) as the sole holder of such Global Security and shall have no
obligations to the beneficial owners thereof. None of the Trustee, any paying agent or any Registrar shall have any responsibility or liability for any acts or omissions of the Depositary with respect to such Global Security, for the records of any
such depositary, including records in respect of beneficial ownership interests in respect of any such Global Security, for any transactions between the Depositary and any agent member or between or among the Depositary, any such agent member and/or
any holder or owner of a beneficial interest in such Global Security, or for any transfers of beneficial interests in any such Global Security. 

Notwithstanding the foregoing, with respect to any Global Security, nothing herein shall prevent the Partnership, the Trustee, or any agent of
the Partnership or the Trustee from giving effect to any written certification, proxy or other authorization furnished by any Depositary (or its nominee), as a Holder, with respect to such Global Security or shall impair, as between such Depositary
and owners of beneficial interests in such Global Security, the operation of customary practices governing the exercise of the rights of such Depositary (or its nominee) as Holder of such Global Security. 

Section 2.08 Temporary Debt Securities. Pending the preparation of definitive Debt Securities of any series, the Partnership may
execute and the Trustee shall authenticate and deliver temporary Debt Securities (printed, lithographed, photocopied, typewritten or otherwise produced) of any authorized denomination, and substantially in the form of the definitive Debt Securities
in lieu of which they are issued, in registered form with such omissions, insertions and variations as may be appropriate for temporary Debt Securities, all as may be determined by the Partnership with the concurrence of the Trustee. Temporary Debt
Securities may contain such reference to any provisions of this Indenture as may be appropriate. Every temporary Debt Security shall be executed by the Partnership and be authenticated by the Trustee upon the same conditions and in substantially the
same manner, and with like effect, as the definitive Debt Securities. 
 If temporary Debt Securities of any series are issued, the
Partnership will cause definitive Debt Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be exchangeable for
definitive Debt Securities of such series upon surrender of the temporary Debt Securities of such series at the office or agency of the Partnership at a Place of Payment for such series, without charge to the Holder thereof, except as provided in
Section 2.07 in connection with a transfer. Upon surrender for cancellation of any one or more temporary Debt Securities of any series, the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor a like
principal amount of definitive Debt Securities of the same series of authorized denominations and of like tenor. Until so exchanged, temporary Debt Securities of any series shall in all respects be entitled to the same benefits under this Indenture
as definitive Debt Securities of such series. 

  
 - 14 - 








 Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or
for the individual Debt Securities represented thereby pursuant to Section 2.07 or this Section 2.08, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby,
whereupon the principal amount of such temporary Global Security shall be reduced for all purposes by the amount to be exchanged and endorsed. 

Section 2.09 Mutilated, Destroyed, Lost or Stolen Debt Securities. If (a) any mutilated Debt Security is surrendered to the
Trustee at its Corporate Trust Office or (b) the Partnership and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and there is delivered to the Partnership and the Trustee such security
or indemnity as may be required by them to save each of them and any paying agent harmless, and neither the Partnership nor the Trustee receives notice that such Debt Security has been acquired by a protected purchaser, then the Partnership shall
execute and, upon a Partnership Order, the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt Security of the same series of like tenor, form, terms and
principal amount, bearing a number not contemporaneously Outstanding. Upon the issuance of any substituted Debt Security, the Partnership or the Trustee may require the payment of a sum sufficient to cover any tax, fee, assessment or other
governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security which has matured or is about to mature or which has been called for redemption shall become mutilated or be destroyed,
lost or stolen, the Partnership may, instead of issuing a substituted Debt Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debt Security) if the applicant for such payment shall furnish
the Partnership and the Trustee with such security or indemnity as either may require to save it harmless from all risk, however remote, and, in case of destruction, loss or theft, evidence to the satisfaction of the Partnership and the Trustee of
the destruction, loss or theft of such Debt Security and of the ownership thereof. 
 Every substituted Debt Security of any series issued
pursuant to the provisions of this Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost or stolen shall constitute an original additional contractual obligation of the Partnership, whether or not the destroyed, lost or
stolen Debt Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of that series duly issued hereunder. All Debt Securities shall be held
and owned upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities, and shall preclude any and all other rights or remedies,
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 

Section 2.10 Cancellation of Surrendered Debt Securities. All Debt Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to the Partnership or any paying agent or a Registrar, be delivered to the Trustee for cancellation by it, or if surrendered to the Trustee, shall be canceled by it, and no Debt Securities shall be issued
in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All canceled Debt Securities held by the Trustee shall be disposed of in accordance with the 

  
 - 15 - 








 
Trustee’s then standard procedures (subject to the record retention requirements of the Exchange Act) and, on request of the Partnership, certification of their disposition delivered to the
Partnership, unless otherwise directed. On request of the Partnership, the Trustee shall deliver to the Partnership canceled Debt Securities held by the Trustee. If the Partnership shall acquire any of the Debt Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the Debt represented thereby unless and until the same are delivered or surrendered to the Trustee for cancellation. The Partnership may not issue new Debt Securities to replace Debt Securities it
has redeemed, paid or delivered to the Trustee for cancellation, except as otherwise provided in this Indenture. 
 Section 2.11
Provisions of the Indenture and Debt Securities for the Sole Benefit of the Parties and the Holders. Nothing in this Indenture or in the Debt Securities, expressed or implied, shall give or be construed to give to any Person, other than the
parties hereto, the Holders or any Registrar or paying agent, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all its covenants, conditions and
provisions being for the sole benefit of the parties hereto, the Holders and any Registrar and paying agents. 
 Section 2.12
Payment of Interest; Interest Rights Preserved. 
 (a) Interest on any Debt Security that is payable and is punctually paid or duly
provided for on any interest payment date shall be paid to the Person in whose name such Debt Security is registered at the close of business on the regular record date for such interest notwithstanding the cancellation of such Debt Security upon
any transfer or exchange subsequent to the regular record date. Payment of interest on Debt Securities shall be made at the Corporate Trust Office of the Trustee (except as otherwise specified pursuant to Section 2.03), or at the option of the
Partnership, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt Security Register or, if provided pursuant to Section 2.03 and in accordance with arrangements satisfactory to the Trustee, at
the option of the Holder by wire transfer to an account designated by the Holder. 
 (b) Subject to the foregoing provisions of this
Section 2.12 and Section 2.17, each Debt Security of a particular series delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security of the same series shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other Debt Security. 
 Section 2.13 Securities Denominated
in Dollars. Except as otherwise specified pursuant to Section 2.03 for Debt Securities of any series, payment of the principal of, and premium, if any, and interest on, Debt Securities of such series will be made in Dollars. 

Section 2.14 Wire Transfers. Notwithstanding any other provision to the contrary in this Indenture, the Partnership shall make any
payment of money required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on, the Debt Securities (whether pursuant to optional or mandatory redemption payments, interest payments or otherwise) by wire
transfer in immediately available funds to an account designated by the Trustee by 11:00 a.m., New York City time, on the date such money is to be paid to the Holders of the Debt Securities in accordance with the terms hereof.

 Section 2.15 Securities Issuable in the Form of a Global Security. 

(a) If the Partnership shall establish pursuant to Sections 2.01 and 2.03 that the Debt Securities of a particular series are to be issued in
whole or in part in the form of one or more Global Securities, then the Partnership shall execute and the Trustee or its agent shall, in accordance with Section 2.05, authenticate and deliver, such Global Security or Securities, which shall
represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented by such Global Security or Securities, or such portion thereof as the Partnership shall
specify in an Officer’s Certificate, shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, shall be delivered by the Trustee or its agent to the Depositary or pursuant to the Depositary’s
instruction and shall bear a legend substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED
REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE PARTNERSHIP OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF
CEDE & CO. OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO., OR TO SUCH OTHER ENTITY AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR
OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 

TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR
SUCH SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO HEREIN.” 

or such other legend as may then be required by the Depositary for such Global Security or Securities. 

(b) Notwithstanding any other provision of this Section 2.15 or of Section 2.07 to the contrary, and subject to the provisions of
paragraph (c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for definitive Debt Securities in registered form, a Global Security may be transferred, in whole but not in
part and in the manner provided in Section 2.07, only by the Depositary to a nominee of the Depositary for such Global Security, or by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or a
nominee of the Depositary to a successor Depositary for such Global Security selected or approved by the Partnership, or to a nominee of such successor Depositary. 

(c) (i) If at any time the Depositary for a Global Security or Securities notifies the Partnership that it is unwilling or unable to continue
as Depositary for such Global Security or 

  
 - 17 - 








 
Securities or if at any time the Depositary for the Debt Securities for such series shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or
regulation, the Partnership shall appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security or Securities is not appointed by the Partnership within 90 days after the
Partnership receives such notice or becomes aware of such ineligibility, the Partnership shall execute, and the Trustee or its agent, upon receipt of a Partnership Order for the authentication and delivery of such individual Debt Securities of such
series in exchange for such Global Security or Securities, will authenticate and deliver, individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the
Global Security or Securities in exchange for such Global Security or Securities. 
 (ii) The Partnership may at any time and
in its sole discretion, subject to the procedures of the Depositary, determine that the Debt Securities of any series or portion thereof issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global
Security or Securities. In such event, or if such Depositary so requests during the continuance of an Event of Default with respect to the series of Debt Securities represented by such Global Security or Securities, the Partnership will execute, and
the Trustee, upon receipt of a Partnership Order for the authentication and delivery of individual Debt Securities of such series in exchange in whole or in part for such Global Security or Securities, will authenticate and deliver individual Debt
Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such series or portion thereof in exchange for such Global Security or Securities. 

(iii) If specified by the Partnership pursuant to Sections 2.01 and 2.03 with respect to Debt Securities issued or issuable in
the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual Debt Securities of such series of like tenor and terms in definitive form on such terms as are
acceptable to the Partnership, the Trustee and such Depositary. Thereupon the Partnership shall execute, and the Trustee or its agent upon receipt of a Partnership Order for the authentication and delivery of definitive Debt Securities of such
series shall authenticate and deliver, without service charge, to each Person specified by such Depositary a new Debt Security or Securities of the same series of like tenor and terms and of any authorized denomination as requested by such Person in
aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and to such Depositary a new Global Security of like tenor and terms and in an authorized denomination equal to the difference, if
any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt Securities delivered to Holders thereof. 

(iv) In any exchange provided for in any of the preceding three paragraphs, the Partnership will execute and the Trustee or its
agent will authenticate and deliver individual Debt Securities. Upon the exchange of the entire principal amount of a Global Security for individual Debt Securities, such Global Security shall be canceled by the Trustee or its agent. Except as
provided in the preceding paragraph, Debt Securities issued in exchange for a Global Security pursuant to this Section 2.15 shall be registered 

  
 - 18 - 








 
in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct or indirect participants or otherwise, shall instruct the
Trustee or the Registrar. The Trustee or the Registrar shall deliver such Debt Securities to the Persons in whose names such Debt Securities are so registered. 

(v) Payments in respect of the principal of and interest on any Debt Securities issued in global form and registered in the
name of the Depositary or its nominee will be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Partnership and the Trustee may treat the Person in whose name the Debt Securities,
including the Global Security, are registered as the owner thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Partnership, the Trustee, any Registrar, the paying agent or any agent of the
Partnership or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its nominee or any of the
Depositary’s direct or indirect participants, or for maintaining, supervising or reviewing any records of the Depositary, its nominee or any of its direct or indirect participants relating to the beneficial ownership interests of the Global
Security, the payments to the beneficial owners of the Global Security of amounts paid to the Depositary or its nominee, or any other matter relating to the actions and practices of the Depositary, its nominee or any of its direct or indirect
participants. None of the Partnership, the Trustee or any such agent will be liable for any delay by the Depositary, its nominee, or any of its direct or indirect participants in identifying the beneficial owners of the Debt Securities, and the
Partnership and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes (including with respect to the registration and delivery, and the respective principal
amounts, of the individual Debt Securities to be issued). 
 Section 2.16 Medium Term Securities. Notwithstanding any contrary
provision herein, if all Debt Securities of a series are not to be originally issued at one time, it shall not be necessary for the Partnership to deliver to the Trustee an Officer’s Certificate, resolutions of the Board of Directors,
supplemental Indenture, Opinion of Counsel or written order or any other document otherwise required pursuant to Section 2.01, 2.03, 2.05 or 13.05 at or prior to the time of authentication of each Debt Security of such series if such documents
are delivered to the Trustee or its agent at or prior to the authentication upon original issuance of the first such Debt Security of such series to be issued; provided, that any subsequent request by the Partnership to the Trustee to authenticate
Debt Securities of such series upon original issuance shall constitute a representation and warranty by the Partnership that, as of the date of such request, the statements made in the Officer’s Certificate delivered pursuant to
Section 2.05 or 13.05 shall be true and correct as if made on such date and that the Opinion of Counsel delivered at or prior to such time of authentication of an original issuance of Debt Securities shall specifically state that it shall
relate to all subsequent issuances of Debt Securities of such series that are identical to the Debt Securities issued in the first issuance of Debt Securities of such series. 

A Partnership Order delivered by the Partnership to the Trustee in the circumstances set forth in the preceding paragraph may provide that
Debt Securities that are the subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time 

  
 - 19 - 








 
upon the telephonic or written order of Persons designated in such written order (any such telephonic instructions to be promptly confirmed in writing by such Person) and that such Persons are
authorized to determine, consistent with the Officer’s Certificate, supplemental Indenture or resolution of the Board of Directors relating to such written order, such terms and conditions of such Debt Securities as are specified in such
Officer’s Certificate, supplemental Indenture or such resolution. 
 Section 2.17 Defaulted Interest. Any interest on any
Debt Security of a particular series which is payable, but is not punctually paid or duly provided for, on the dates and in the manner provided in the Debt Securities of such series and in this Indenture (herein called “Defaulted
Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant record date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Partnership, at its election in each case, as provided in
clause (i) or (ii) below: 
 (i) The Partnership may elect to make payment of any Defaulted Interest to the Persons
in whose names the Debt Securities of such series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Partnership shall notify the Trustee in
writing of the amount of Defaulted Interest proposed to be paid on each such Debt Security of such series and the date of the proposed payment, and at the same time the Partnership shall deposit with the Trustee an amount of money equal to the
aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days
prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Partnership of such special record date and, in the name and at the
expense of the Partnership, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage pre-paid, to each Holder thereof at its address as it appears in the Debt
Security Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Debt Securities of such series are registered at the close of business on such special record date. 
 (ii)
The Partnership may make payment of any Defaulted Interest on the Debt Securities of such series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debt Securities of such series may be listed,
and upon such notice as may be required by such exchange, if, after notice given by the Partnership to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.18 CUSIP and ISIN Numbers. The Partnership in issuing the Debt Securities may use “CUSIP” and corresponding
“ISIN” or other similar numbers (if then generally in use), 

  
 - 20 - 








 
and, if so, the Trustee shall use “CUSIP” and corresponding “ISIN” or other similar numbers in notices of redemption as a convenience to Holders; provided that any such notice
may state that no representation is made as to the accuracy of such numbers either as printed on the Debt Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on
the Debt Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Partnership will promptly notify the Trustee in writing of any change in the “CUSIP” or “ISIN” or other similar
numbers. 
 Section 2.19 Calculation of Original Issue Discount. If any Original Issue Discount Debt Securities are Outstanding,
the Partnership shall file with the Trustee promptly at the end of each calendar year (i) a written notice specifying the amount of original issue discount (including daily rates and accrual periods) accrued on Outstanding Original Issue
Discount Debt Securities as of the end of such year and (ii) such other specific information relating to such Original Issue Discount Debt Securities as may be required to be provided to the Trustee or to the holders of the Debt Securities
pursuant to the Code, and the regulations issued thereunder. 
 ARTICLE III 

REDEMPTION OF DEBT SECURITIES 

Section 3.01 Applicability of Article. The provisions of this Article shall be applicable to the Debt Securities of any series
which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 2.03 for Debt Securities of such series. 

Section 3.02 Notice of Redemption; Selection of Debt Securities. In case the Partnership shall desire to exercise the right to
redeem all or, as the case may be, any part of the Debt Securities of any series in accordance with their terms, by resolution of the Board of Directors or a supplemental Indenture, the Partnership shall fix a date for redemption and shall give
notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities of such series so to be redeemed as a whole or in part, in the manner provided in Section 13.03; provided,
however, such notice may be given more than 60 days prior to the Redemption Date if the notice is given in connection with a satisfaction and discharge pursuant to Section 11.02(a). The notice if given in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Debt Security of a series designated for redemption as a whole
or in part shall not affect the validity of the proceedings for the redemption of any other Debt Security of such series. 
 Each such
notice of redemption shall specify (i) the Redemption Date, (ii) the redemption price at which Debt Securities of such series are to be redeemed (or the method of calculating such redemption price), (iii) the Place or Places of
Payment that payment will be made upon presentation and surrender of such Debt Securities, (iv) that any interest accrued to the Redemption Date will be paid as specified in said notice, (v) that the redemption is for a sinking fund
payment (if applicable), (vi) that, unless otherwise specified in such notice, if the Partnership defaults in making such redemption payment, the paying agent is prohibited from making such payment pursuant to the terms of this Indenture,
(vii) that on and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue, (viii) that in the 

  
 - 21 - 








 
case of Original Issue Discount Securities original issue discount accrued after the Redemption Date will cease to accrue, (ix) the terms of the Debt Securities of that series pursuant to
which the Debt Securities of that series are being redeemed and (x) that no representation is made as to the correctness or accuracy of the CUSIP or ISIN number, if any, listed in such notice or printed on the Debt Securities of that series. If
less than all the Debt Securities of a series are to be redeemed at any time, the notice of redemption shall specify the certificate numbers of the Debt Securities of that series to be redeemed that are not in global form. In case any Debt Security
of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the Redemption Date, upon surrender of such Debt Security, a new Debt
Security or Debt Securities of that series in principal amount equal to the unredeemed portion thereof, will be issued. 
 At least five
days before giving of any notice of redemption, unless the Trustee consents to a shorter period, the Partnership shall give written notice to the Trustee of the Redemption Date, the principal amount of Debt Securities to be redeemed and the series
and terms of the Debt Securities pursuant to which such redemption will occur. Such notice shall be accompanied by an Officer’s Certificate and an Opinion of Counsel from the Partnership to the effect that such redemption will comply with the
conditions herein, and such notice may be revoked at any time prior to the giving of a notice of redemption to the Holders pursuant to this Section 3.02. If fewer than all the Debt Securities of a series are to be redeemed, the record date
relating to such redemption shall be selected by the Partnership and given in writing to the Trustee, which record date shall be not less than three days after the date of notice to the Trustee. 

By 11:00 a.m., New York City time, on the Redemption Date for any Debt Securities, the Partnership shall deposit with the Trustee or with a
paying agent (or, if the Partnership is acting as its own paying agent, segregate and hold in trust) an amount of money in Dollars (except as provided pursuant to Section 2.03) sufficient to pay the redemption price of such Debt Securities or
any portions thereof that are to be redeemed on that date, together with any interest accrued to the Redemption Date. 
 If less than all
the Debt Securities of like tenor and terms of a series are to be redeemed (other than pursuant to a mandatory sinking fund), the Trustee shall select, on a pro rata basis, by lot or by such other method as in its sole discretion it shall deem
appropriate and fair (or, in the case of Debt Securities represented by a Global Security, by such method as the Depositary may require), the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed. In any case
where more than one Debt Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Debt Security of such series. The Trustee shall
promptly notify the Partnership in writing of the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed. If any Debt Security called for
redemption shall not be so paid upon surrender thereof on such Redemption Date, the principal, premium, if any, and interest shall bear interest until paid from the Redemption Date at the rate borne by the Debt Securities of that series. If less
than all the Debt Securities of unlike tenor and terms of a series are to be redeemed, the particular Debt Securities to be redeemed shall be selected by the Partnership. Provisions of this Indenture that apply to Debt Securities called for
redemption also apply to portions of Debt Securities called for redemption. 

  
 - 22 - 








 Section 3.03 Payment of Debt Securities Called for Redemption. If notice of
redemption has been given as provided in Section 3.02, the Debt Securities or portions of Debt Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the Place or Places of
Payment stated in such notice at the applicable redemption price, together with any interest accrued to the Redemption Date, and on and after said date (unless the Partnership shall default in the payment of such Debt Securities at the applicable
redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt Securities of any series so called for redemption shall cease to accrue, and any original issue discount in the case of
Original Issue Discount Securities shall cease to accrue. On presentation and surrender of such Debt Securities at the Place or Places of Payment in said notice specified, the said Debt Securities or the specified portions thereof shall be paid and
redeemed by the Partnership at the applicable redemption price, together with any interest accrued thereon to the Redemption Date. 
 Any
Debt Security that is to be redeemed only in part shall be surrendered at the Place of Payment with, if the Partnership, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the
Partnership, the Registrar and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing, and the Partnership shall execute, and the Trustee shall authenticate and deliver to the Holder of such Debt Security without
service charge, a new Debt Security or Debt Securities of the same series, of like tenor and form, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the
principal of the Debt Security so surrendered; except that if a Global Security is so surrendered, the Partnership shall execute, and the Trustee shall authenticate and deliver to the Depositary for such Global Security, without service charge, a
new Global Security in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Debt Security providing appropriate space for such notation, at the option of the
Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion thereof. 

Section 3.04 Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of
Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Debt
Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as an “optional sinking fund payment.” 

In lieu of making all or any part of any mandatory sinking fund payment with respect to any Debt Securities of a series in cash, the
Partnership may at its option (a) deliver to the Trustee Debt Securities of that series theretofore purchased or otherwise acquired by the Partnership or (b) receive credit for the principal amount of Debt Securities of that series which
have been redeemed either at the election of the Partnership pursuant to the terms of such Debt Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Debt Securities, resolution or
supplemental Indenture; provided, that such Debt Securities have not been previously so credited. Such Debt Securities shall be received and credited for such purpose by the Trustee at the redemption price specified in such Debt Securities,
resolution or supplemental Indenture for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly. 

  
 - 23 - 








 Section 3.05 Redemption of Debt Securities for Sinking Fund. Not less than 60 days
prior to each sinking fund payment date for any series of Debt Securities, the Partnership will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms
of that series, any resolution or supplemental Indenture, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Debt Securities of that series
pursuant to this Section 3.05 (which Debt Securities, if not previously redeemed, will accompany such certificate) and whether the Partnership intends to exercise its right to make any permitted optional sinking fund payment with respect to
such series. Such certificate shall also state that no Event of Default has occurred and is continuing with respect to such series. Such certificate shall be irrevocable, and upon its delivery, the Partnership shall be obligated to make the cash
payment or payments therein referred to, if any, by 11:00 a.m., New York City time, on the next succeeding sinking fund payment date. Failure of the Partnership to deliver such certificate (or to deliver the Debt Securities specified in this
paragraph) shall not constitute a Default, but such failure shall require that the sinking fund payment due on the next succeeding sinking fund payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of such Debt Securities subject to a mandatory sinking fund payment without the option to deliver or credit Debt Securities as provided in this Section 3.05 and without the right to make any optional sinking fund payment, if
any, with respect to such series. 
 Any sinking fund payment or payments (mandatory or optional) made in cash plus any unused balance of
any preceding sinking fund payments made in cash which shall equal or exceed $100,000 (or a lesser sum if the Partnership shall so request) with respect to the Debt Securities of any particular series shall be applied by the Trustee on the sinking
fund payment date on which such payment is made (or, if such payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Debt Securities at the redemption price
specified in such Debt Securities, resolution or supplemental Indenture for operation of the sinking fund together with any accrued interest to the date fixed for redemption. Any sinking fund money not so applied or allocated by the Trustee to the
redemption of Debt Securities shall be added to the next cash sinking fund payment received by the Trustee for such series and, together with such payment, shall be applied in accordance with the provisions of this Section 3.05. Any and all
sinking fund money with respect to the Debt Securities of any particular series held by the Trustee on the last sinking fund payment date with respect to Debt Securities of such series and not held for the payment or redemption of particular Debt
Securities shall be applied by the Trustee, together with other money, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities of that series at its Stated Maturity. 

The Trustee shall select the Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph
of Section 3.02, and the Partnership shall cause notice of the redemption thereof to be given in the manner provided in Section 3.02 except that the notice of redemption shall also state that the Debt Securities are being redeemed by
operation of the sinking fund. Such notice having been duly given, the redemption of such Debt Securities shall be made upon the terms and in the manner stated in Section 3.03. 

  
 - 24 - 








 The Trustee shall not redeem any Debt Securities of a series with sinking fund money or mail any
notice of redemption of such Debt Securities by operation of the sinking fund for such series during the continuance of a Default in payment of interest on such Debt Securities or of any Event of Default (other than an Event of Default occurring as
a consequence of this paragraph) with respect to such Debt Securities, except that if the notice of redemption of any such Debt Securities shall theretofore have been mailed in accordance with the provisions hereof, the Trustee shall redeem such
Debt Securities if cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance with the terms of this Article III. Except as aforesaid, any money in the sinking fund for such series at the time when any such
Default or Event of Default shall occur and any money thereafter paid into such sinking fund shall, during the continuance of such Default or Event of Default, be held as security for the payment of such Debt Securities; provided, however, that in
case such Default or Event of Default shall have been cured or waived as provided herein, such money shall thereafter be applied on the next sinking fund payment date for such Debt Securities on which such money may be applied pursuant to the
provisions of this Section 3.05. 
 ARTICLE IV 

PARTICULAR COVENANTS OF THE PARTNERSHIP 

Section 4.01 Payment of Principal of, and Premium, If Any, and Interest on, Debt Securities. The Partnership, for the benefit of
each series of Debt Securities, will duly and punctually pay or cause to be paid the principal of, and premium, if any, and interest on, each of the Debt Securities at the place, at the respective times and in the manner provided herein or in the
Debt Securities. Each installment of interest on the Debt Securities (other than those represented by a Global Security) may at the Partnership’s option be paid by mailing checks for such interest payable to the Person entitled thereto pursuant
to Section 2.07(a) to the address of such Person as it appears on the Debt Security Register. 
 The Partnership shall pay interest on
overdue principal or premium, if any, at the rate specified therefor in the Debt Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 

Section 4.02 Maintenance of Offices or Agencies for Registration of Transfer, Exchange and Payment of Debt Securities. The
Partnership will maintain in each Place of Payment for any series of Debt Securities an office or agency where Debt Securities of such series may be presented or surrendered for payment. The Partnership shall also maintain (in or outside such Place
of Payment) an office or agency where Debt Securities of such series may be surrendered for transfer or exchange and where notices and demands to or upon the Partnership in respect of the Debt Securities of such series and this Indenture may be
served. Unless otherwise specified in a resolution of the Board of Directors or an Indenture supplemental hereto with respect to a series of Debt Securities, such office or agency shall be the Corporate Trust Office of the Trustee. The Partnership
will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Partnership shall fail to maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee, and the Partnership hereby appoints the Trustee as its agent to receive all presentations, surrenders,
notices and demands. 

  
 - 25 - 








 The Partnership may also from time to time designate different or additional offices or agencies
to be maintained for such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the Partnership of its
obligations described in the preceding paragraph. The Partnership will give prompt written notice to the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or additional
office or agency. 
 Section 4.03 Appointment to Fill a Vacancy in the Office of Trustee. The Partnership, whenever necessary to
avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.08, a Trustee, so that there shall at all times be a Trustee hereunder with respect to each series of Debt Securities. 

Section 4.04 Duties of Paying Agents, etc. (a) The Partnership shall cause each paying agent, if any, other than the Trustee,
to execute and deliver to the Trustee an instrument in which such agent shall agree with the Trustee, subject to the provisions of this Section 4.04, 

(i) that it will hold all sums held by it as such agent for the payment of the principal of, and premium, if any, or interest
on, the Debt Securities of any series (whether such sums have been paid to it by the Partnership or by any other obligor on the Debt Securities of such series) in trust for the benefit of the Holders of the Debt Securities of such series; 

(ii) that it will give the Trustee notice of any failure by the Partnership (or by any other obligor on the Debt Securities of
such series) to make any payment of the principal of, and premium, if any, or interest on, the Debt Securities of such series when the same shall be due and payable; and 

(iii) that it will at any time during the continuance of an Event of Default, upon the written request of the Trustee,
forthwith pay to the Trustee all sums so held by it as such agent. 
 (b) If the Partnership shall act as its own paying agent, it will, on
or before each due date of the principal of, and premium, if any, or interest on, the Debt Securities of any series, set aside, segregate and hold in trust for the benefit of the Holders of the Debt Securities of such series a sum sufficient to pay
such principal, premium, if any, or interest so becoming due. The Partnership will promptly notify the Trustee of any failure by the Partnership to take such action or the failure by any other obligor on such Debt Securities to make any payment of
the principal of, and premium, if any, or interest on, such Debt Securities when the same shall be due and payable. 
 (c) Anything in this
Section 4.04 to the contrary notwithstanding, the Partnership may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust
by it or any paying agent, as required by this Section 4.04, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Partnership or such paying agent. 

  
 - 26 - 








 (d) Whenever the Partnership shall have one or more paying agents with respect to any series of
Debt Securities, it will, prior to each due date of the principal of, and premium, if any, or interest on, any Debt Securities of such series, deposit with any such paying agent a sum sufficient to pay the principal, premium or interest so becoming
due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless any such paying agent is the Trustee) the Partnership will promptly notify the Trustee of its action or failure so to act. 

(e) Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this
Section 4.04 is subject to the provisions of Section 11.05. 
 Section 4.05 SEC Reports; Financial Statements. 

(a) The Partnership shall, so long as any of the Debt Securities are Outstanding, file with the Trustee, within 15 days after it files the
same with the SEC, unless such reports are available on the SEC’s EDGAR filing system (or any successor thereto), copies of the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing
as the SEC may by rules and regulations prescribe) that the Partnership is required to file with the SEC pursuant to Section 13 or 15 (d) of the Exchange Act. The Partnership shall also comply with the provisions of Section 314(a) of
the TIA. 
 (b) Delivery of such reports, information and documents to the Trustee is for informational purposes only and the Trustee’s

with respect to the Debt Securities of any series, omit in any particular instance to comply with any covenant set forth in this Article IV (except Section 4.01) or made applicable to such Debt Securities pursuant to Section 2.03, if,
before or after the time for such compliance, the Holders of at least a majority in principal amount of the Outstanding Debt Securities of each series affected, waive such compliance in such instance with such covenant, but no such waiver shall
extend to or affect such covenant except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Partnership and the duties of the Trustee in respect of any such covenant shall remain in full force
and effect. 
 ARTICLE V 

HOLDERS’ LISTS AND REPORTS BY THE TRUSTEE 

Section 5.01 Partnership to Furnish Trustee Information as to Names and Addresses of Holders; Preservation of Information. The

(i) contained in the most recent list furnished to it as provided in this Section 5.01 or (ii) received by it in the capacity of paying agent or Registrar (if so acting) hereunder. 

The Trustee may destroy any list furnished to it as provided in this Section 5.01 upon receipt of a new list so furnished.

 Section 5.02 Communications to Holders. Holders may communicate pursuant to
Section 312(b) of the TIA with other Holders with respect to their rights under this Indenture or the Debt Securities. The Partnership, the Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the TIA. 

Section 5.03 Reports by Trustee. Within 60 days after each [    ], beginning with the first
[    ] following the date of this Indenture, and in any event on or before April 1 in each year, the Trustee shall mail to Holders a brief report dated as of such [    ] that complies with
Section 313(a) of the TIA; provided, however, that if no event described in Section 313(a) of the TIA has occurred within the twelve months preceding the reporting date, no report need be transmitted. The Trustee also shall comply with
Section 313(b) of the TIA. 
 Reports pursuant to this Section 5.03 shall be transmitted by mail: 

(a) to all Holders, as the names and addresses of such Holders appear in the Debt Security Register; and 

(b) except in the cases of reports under Section 313(b)(2) of the TIA, to each Holder of a Debt Security of any series whose name and
address appear in the information preserved at the time by the Trustee in accordance with Section 5.01. 
 A copy of each report at the
time of its mailing to Holders shall be filed with the SEC and each stock exchange (if any) on which the Debt Securities of any series are listed. The Partnership agrees to notify promptly the Trustee whenever the Debt Securities of any series
become listed on any stock exchange and of any delisting thereof. 
 Section 5.04 Record Dates for Action by Holders. If the
Partnership shall solicit from the Holders of Debt Securities of any series any action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action), the Partnership may, at
its option, by resolution of the Board of Directors, fix in advance a record date for the determination of Holders of Debt Securities entitled to take such action, but the Partnership shall have no obligation to do so. Any such record date shall be
fixed at the Partnership’s discretion. If such a record date is fixed, such action may be sought or given before or after the record date, but only the Holders of Debt Securities of record at the close of business on such record date shall be
deemed to be Holders of Debt Securities for the purpose of determining whether Holders of the requisite proportion of Debt Securities of such series Outstanding have authorized or agreed or consented to such action, and for that purpose the Debt
Securities of such series Outstanding shall be computed as of such record date. 
 ARTICLE VI

interest upon any Debt Securities of that series as and when the same shall become due and payable, and continuance of such default for a period of 30 days; or 

  
 - 29 - 








 (b) default in the payment of the principal of or premium, if any, on any Debt Securities of that
series as and when the same shall become due and payable, whether at Stated Maturity, upon redemption, by declaration, upon required repurchase or otherwise; or 

(c) default in the payment of any sinking fund payment with respect to any Debt Securities of that series as and when the same shall become
due and payable; or

part of the Partnership in the Debt Securities of that series, in any resolution of the Board of Directors authorizing the issuance of that series of Debt Securities, in this Indenture with respect to such series or in any supplemental Indenture
with respect to such series (other than a covenant a default in the performance of which is elsewhere in this Section specifically dealt with), continuing for a period of 60 days after the date on which written notice specifying such failure and
requiring the Partnership to remedy the same shall have been given, to the Partnership by the Trustee or to the Partnership and the Trustee by the Holders of at least 25% in aggregate principal amount of the Debt Securities of that series at the
time Outstanding; or 
 (e) the Partnership, pursuant to or within the meaning of any Bankruptcy Law, 

(i) commences a voluntary case, 

(ii) consents to the entry of an order for relief against it in an involuntary case, 

(iii) consents to the appointment of a Custodian of it or for all or substantially all of its property; or 

(iv) makes a general assignment for the benefit of its creditors; 

(f) a court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

or 
 (iii) orders the liquidation of the Partnership, and the order or decree remains unstayed and in effect for 60 days; or

Default described in clause (a), (b), (c), (d) or (g) with respect to Debt Securities of that series at the time Outstanding occurs and is continuing, unless the principal of, premium, if any, and accrued and unpaid interest on all the
Debt 

  
 - 30 - 








 
Securities of that series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Debt Securities of that series
then Outstanding hereunder, by notice in writing to the Partnership (and to the Trustee if given by Holders), may declare the principal of (or, if the Debt Securities of that series are Original Issue Discount Debt Securities, such portion of the
principal amount as may be specified in the terms of that series), premium, if any, and accrued and unpaid interest on all the Debt Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the Debt Securities of that series contained to the contrary notwithstanding. If an Event of Default described in clause (e) or (f) occurs, then and in each and every
such case, unless the principal of and accrued and unpaid interest on all the Debt Securities shall have become due and payable, the principal of (or, if any Debt Securities of that series are Original Issue Discount Debt Securities, such portion of
the principal amount as may be specified in the terms of that series), premium, if any, and accrued and unpaid interest on all the Debt Securities then Outstanding hereunder shall ipso facto become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holders, anything in this Indenture or in the Debt Securities contained to the contrary notwithstanding. 

The Holders of a majority in aggregate principal amount of the Debt Securities of a particular series by written notice to the Trustee may
rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction already rendered and if all existing Events of Default with respect to Debt Securities of that series
have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely because of acceleration and all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements
and advances of the Trustee, its agents and counsel. Upon any such rescission, the parties hereto shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the parties hereto shall
continue as though no such proceeding had been taken. 
 Section 6.02 Collection of Debt by Trustee, etc. If an Event of Default
occurs and is continuing, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid or enforce the
performance of any provision of the Debt Securities of the affected series or this Indenture, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against the Partnership or
any other obligor upon the Debt Securities of such series (and collect in the manner provided by law out of the property of the Partnership or any other obligor upon the Debt Securities of such series wherever situated the money adjudged or decreed
to be payable). In case there shall be pending proceedings for the bankruptcy or for the reorganization of the Partnership or any other obligor upon the Debt Securities of any series under any Bankruptcy Law, or in case a Custodian shall have been
appointed for its property, or in case of any other similar judicial proceedings relative to any of the Partnership or any other obligor upon the Debt Securities of any series, its creditors or its property, the Trustee, irrespective of whether the
principal of Debt Securities of any series shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02,
shall be entitled and empowered, by intervention in such proceedings or otherwise, to file 

  
 - 31 - 








 
and prove a claim or claims for the whole amount of principal, premium, if any, and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion
of the principal amount as may be specified in the terms of such series) owing and unpaid in respect of the Debt Securities of such series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of
the Trustee (including any claim for reasonable compensation to the Trustee, its agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its gross
negligence or willful misconduct) and of the Holders thereof allowed in any such judicial proceedings relative to the Partnership, or any other obligor upon the Debt Securities of such series, its creditors or its property, and to collect and
receive any money or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of such Holders and of the Trustee on their behalf, and any receiver, assignee or trustee in bankruptcy
or reorganization is hereby authorized by each of such Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to such Holders, to pay to the Trustee such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other reasonable expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its gross negligence or willful
misconduct. 
 All rights of action and of asserting claims under this Indenture, or under any of the Debt Securities of any series, may be
enforced by the Trustee without the possession of any such Debt Securities, or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment (except for any amounts payable to the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the Holders of all the Debt Securities in respect of which such action was
taken. 
 In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it
by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any
covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

Section 6.03 Application of Money Collected by Trustee. Any money or other property collected by the Trustee pursuant to
Section 6.02 with respect to Debt Securities of any series or, after an Event of Default, any money or other property distributable in respect of the Partnership’s obligations under this Indenture shall be applied, in the order following,
at the date or dates fixed by the Trustee for the distribution of such money or other property, upon presentation of the several Debt Securities of such series in respect of which money or other property have been collected, and the notation thereon
of the payment, if only partially paid, and upon surrender thereof if fully paid: 
 FIRST: To the payment of all money due the Trustee
(including any predecessor trustee) pursuant to Section 7.06; 

  
 - 32 - 








 SECOND: In case the principal of the Outstanding Debt Securities in respect of which such money
has been collected shall not have become due, to the payment of interest on the Debt Securities of such series in the order of the maturity of the installments of such interest, with interest (to the extent that such interest has been collected by
the Trustee) upon the overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities of such series, such payments to be made ratably to the Persons entitled
thereto, without discrimination or preference; 
 THIRD: In case the principal of the Outstanding Debt Securities in respect of which such
money has been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Debt Securities of such series for principal and premium, if any, and interest, with interest on the
overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by
the Debt Securities of such series; and, in case such money shall be insufficient to pay in full the whole amount so due and unpaid upon the Debt Securities of such series, then to the payment of such principal and premium, if any, and interest,
without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any installment of interest over any other installment of interest, or of any Debt Security of such series over
any Debt Security of such series, ratably to the aggregate of such principal and premium, if any, and interest; and 
 FOURTH: The
remainder, if any, shall be paid to the Partnership, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. 

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.03. At least 15 days before such
record date, the Partnership shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. 

Section 6.04 Limitation on Suits by Holders. No Holder of any Debt Security of any series shall have any right by virtue or by
availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 25% in
aggregate principal amount of the Outstanding Debt Securities of that series shall have made written request upon the Trustee to institute such action or proceedings in respect of such Event of Default in its own name as Trustee hereunder and shall
have offered to the Trustee such indemnity or security satisfactory to the Trustee as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice,
request and offer of indemnity or security satisfactory to the Trustee shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustee pursuant to
Section 6.06; it being understood and intended, and being expressly covenanted by the Holder of every Debt Security with every other Holder and the Trustee, that 

  
 - 33 - 








 
no one or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or prejudice the rights of any Holders, or to
obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all such Holders. For the protection
and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 

Notwithstanding any other provision in this Indenture, however, the right of any Holder of any Debt Security to receive payment of the
principal of, and premium, if any, and (subject to Section 2.12) interest on, such Debt Security, on or after the respective due dates expressed in such Debt Security, and to institute suit for the enforcement of any such payment on or after
such respective dates, shall not be impaired or affected without the consent of such Holder. 
 Section 6.05 Remedies Cumulative;
Delay or Omission in Exercise of Rights Not a Waiver of Default. All powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of
any other powers and remedies available to the Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and no delay or omission of the
Trustee or of any Holder to exercise any right or power accruing upon any Default occurring and continuing as aforesaid, shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence therein; and,
subject to the provisions of Section 6.04, every power and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee or by the
Holders. 
 Section 6.06 Rights of Holders of Majority in Principal Amount of Debt Securities to Direct Trustee and to Waive
Default. The Holders of not less than a majority in aggregate principal amount of the Debt Securities of any series at the time Outstanding shall have the right to direct the time, method and place of conducting any proceeding for any remedy
available to the Trustee, or of exercising any right, trust or power conferred on the Trustee, with respect to the Debt Securities of such series; provided, however, that such direction shall not be otherwise than in accordance with law and the
provisions of this Indenture, and that subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee, in its sole discretion, being advised by counsel shall determine that the
action so directed may not lawfully be taken or is inconsistent with any provision of this Indenture, or if the Trustee, in its sole discretion, shall determine that the action so directed would involve it in personal liability or would be unduly
prejudicial to Holders of Debt Securities of such series not taking part in such direction (it being understood that the Trustee shall not be required to make any such determination); and provided, further, however, that nothing contained in this
Indenture shall impair the right of the Trustee to take any action deemed proper by the Trustee and which is not inconsistent with such direction by such Holders. The Holders of not less than a majority in aggregate principal amount of the Debt
Securities of any series at the time Outstanding may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series, except a Default or Event of Default in the
payment of the principal of, and premium, if any, or interest on, any of the Debt Securities and a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without


  
 - 34 - 








 
the consent of each Holder affected thereby. In case of any such waiver, such Default shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for every
purpose of this Indenture, and the Partnership, the Trustee and the Holders of the Debt Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon. 
 Section 6.07 Trustee to Give Notice of Defaults Known
to It, but May Withhold Such Notice in Certain Circumstances. The Trustee shall, within 90 days after the occurrence of any Default with respect to a series of Debt Securities, give to the Holders thereof, in the manner provided in
Section 13.03, notice of such Default with respect to such series known to the Trustee, unless such Defaults shall have been cured or waived before the giving of such notice; provided, that, except in the case of Default in the payment of the
principal of, or premium, if any, or interest on, any of the Debt Securities of such series or in the making of any sinking fund payment with respect to the Debt Securities of such series, the Trustee shall be protected in withholding such notice if
and so long as the board of directors, the executive committee, or a committee of directors or Trust Officers, of the Trustee in good faith determines that the withholding of such notice is in the interests of the Holders thereof. 

Section 6.08 Requirement of an Undertaking to Pay Costs in Certain Suits under the Indenture or Against the Trustee. All parties
to this Indenture agree, and each Holder of any Debt Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in
any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit in the manner and to the extent provided in the TIA, and that such court may
in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 6.08 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 25 percent in principal amount of the Outstanding Debt
Securities of that series or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any Debt Security on or after the due date for such payment expressed in such Debt
Security.

authority, acts of God; earthquakes; fire; flood; terrorism; wars and other military disturbances; sabotage; epidemics; riots; interruptions; loss or malfunctions of utilities, computer (hardware or software) or communication services; accidents;
labor disputes; acts of civil or military authority and governmental action; and 
 (n) in order to comply with applicable tax laws
(inclusive of rules, regulations and interpretations promulgated by competent authorities) related to the Indenture in effect from time to time (“Applicable Tax Law”) that a foreign financial institution, issuer, trustee, paying agent or
other party is or has agreed to be subject to, the Partnership agrees (i) to provide to Trustee and the Agents upon their written request such information known to the Partnership about the parties and/or transactions (including any
modification to the terms of such transactions) so the Trustee and the Agents, as applicable, can determine whether they have tax related obligations under Applicable Tax Law, (ii) that the Trustee and the Agents shall be entitled to make any
withholding or deduction from payments to the extent necessary to comply with Applicable Tax Law for which neither the Trustee nor any Agent shall not have any liability and (iii) to hold harmless the Trustee and the Agents for any Losses it
may suffer due to the actions it takes to comply with Applicable Tax Law. The terms of this section shall survive the termination of this Indenture. 

Section 7.03 Trustee Not Liable for Recitals in Indenture or in Debt Securities. The recitals contained herein, in the Debt
Securities (except the Trustee’s certificates of authentication) shall be taken as the statements of the Partnership, and the Trustee or any authenticating agent assumes no responsibility for the correctness of the same. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the Debt Securities of any series. The Trustee shall not be accountable for the use or application by the Partnership of any of the Debt Securities or of the proceeds thereof.
The Trustee shall not be responsible to make any calculation with respect to any matter under this Indenture. The Trustee shall have no duty to monitor or investigate the Partnership’s compliance with or the breach of, or cause to be performed
or observed, any representation, warranty, or covenant, or agreement of any Person, other than the Trustee, made in this Indenture. 

  
 - 38 - 








 Section 7.04 Trustee, Paying Agent or Registrar May Own Debt Securities. The Trustee
or any authenticating agent or any paying agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Debt Securities and, subject to the provisions of the TIA relating to conflicts of interest and preferential
claims, may otherwise deal with the Partnership with the same rights it would have if it were not Trustee, paying agent or Registrar. 

Section 7.05 Money Received by Trustee to Be Held in Trust. Subject to the provisions of Section 11.05, all money received by
the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which it was received, but need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for
interest on any money received by it hereunder. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such money shall be paid from time to time to the Partnership upon a Partnership Order. 

Section 7.06 Compensation and Reimbursement. The Partnership covenants and agrees to pay in Dollars to the Trustee from time to
time such compensation as the Partnership and the Trustee shall from time to time agree in writing, and the Trustee shall be entitled to, compensation for all services rendered by it hereunder (which shall not be limited by any provision of law in
regard to the compensation of a trustee of an express trust), and, except as otherwise expressly provided herein, the Partnership will pay or reimburse in Dollars the Trustee upon its request for all reasonable expenses, disbursements and advances
incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents, attorneys and counsel and of all Persons not regularly in its
employ), including without limitation, Section 6.02, except any such expense, disbursement or advances as may arise from its gross negligence or willful misconduct. The Partnership also covenants to indemnify in Dollars the Trustee for, and to
hold it harmless against, any loss, liability, damage, claim or expense, including fees and expenses of counsel, including taxes (other than taxes based upon, measured by or determined by the income of the Trustee) incurred without gross negligence
or willful misconduct on the part of the Trustee, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against any claim (whether asserted by the
Partnership, or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, or in connection with enforcing the provisions of this Section. The Partnership and the Holders
agree that as security for the performance of the obligations of the Partnership under this Section the Trustee shall be secured by a Lien prior to that of the Debt Securities upon all property and funds held or collected by the Trustee, as such,
except funds held in trust for the payment of principal of, and premium, if any, or interest on, particular Debt Securities. 
 When the
Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(e) or (f) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy
Law. 
 The obligations of the Partnership under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the
Trustee for expenses, disbursements and advances, and the Lien referred to herein, shall constitute additional Debt hereunder and shall survive the satisfaction and discharge of this Indenture, the termination for any reason of this Indenture, and
the resignation or removal of the Trustee. 

  
 - 39 - 








 “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence, willful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

Section 7.07 Right of Trustee to Rely on an Officer’s Certificate Where No Other Evidence Specifically Prescribed. Except as
otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officer’s
Certificate or Opinion of Counsel delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the faith thereof. 
 Section 7.08 Separate Trustee; Replacement of Trustee. The Partnership
may, but need not, appoint a separate Trustee for any one or more series of Debt Securities. The Trustee or any successor hereafter appointed may resign with respect to one or more or all series of Debt Securities at any time by giving notice to the
Partnership. The Holders of a majority in principal amount of the Debt Securities of a particular series may remove the Trustee for such series and only such series by so notifying the Trustee and may appoint a successor Trustee. The Partnership may
at any time remove the Trustee with respect to the Debt Securities of any particular series by giving the Trustee written notice of removal and thereupon appoint a successor trustee, provided that (i) no Default exists at time of such removal,
(ii) such Trustee was not appointed by the Holders of such series pursuant to this Section 7.08 and (iii) the corporate trust business of the successor Trustee is of nationally recognized standing. The Partnership shall remove the
Trustee if: 
 (a) the Trustee fails to comply with Section 7.10; 

(b) the Trustee is adjudged bankrupt or insolvent; 

(c) a Custodian takes charge of the Trustee or its property; or 

(d) the Trustee otherwise becomes incapable of acting. 

If the Trustee resigns, is removed by the Partnership or by the Holders of a majority in principal amount of the Debt Securities of a
particular series and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Partnership
shall promptly appoint a successor Trustee. No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable
requirements of this Section 7.08. 

  
 - 40 - 








 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee
and to the Partnership. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail
a notice of its succession to Holders of Debt Securities of each applicable series. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, provided all sums owing to the Trustee hereunder have been
paid and subject to the Lien provided for in Section 7.06. 
 If a successor Trustee does not take office within 30 days after the
retiring Trustee gives notice of resignation or is removed, the retiring Trustee or the Holders of 25% in principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment of a
successor Trustee for the Debt Securities of such series. 
 If the Trustee fails to comply with Section 7.10, any Holder of Debt
Securities of any applicable series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series. 

Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the Partnership’s obligations under Section 7.06,
and the Lien provided for therein, shall continue for the benefit of the retiring Trustee. 
 In the case of the appointment hereunder of a
separate or successor Trustee with respect to the Debt Securities of one or more series, the Partnership, any retiring Trustee and each successor or separate Trustee with respect to the Debt Securities of any applicable series shall execute and
deliver an Indenture supplemental hereto (i) which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of any retiring Trustee with respect to the Debt Securities of
any series as to which any such retiring Trustee is not retiring shall continue to be vested in such retiring Trustee and (ii) that shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or
facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental Indenture shall constitute such Trustees co-trustees of the same trust and that each such separate,
retiring or successor Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee. 

Section 7.09 Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or
substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee. 

In case at the time such successor or successors to the Trustee by merger, conversion, consolidation or transfer shall succeed to the trusts
created by this Indenture any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Debt Securities so
authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of any predecessor hereunder or in the name of the successor
to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Debt Securities or in this Indenture provided that the certificate of the Trustee shall have. 

  
 - 41 - 








 Section 7.10 Eligibility; Disqualification. If the Trustee shall have or acquire any
conflicting interest within the meaning of the TIA, it shall either eliminate such conflicting interest or resign to the extent, in the manner and with the effect, and subject to the conditions, provided in the TIA and this Indenture. The Trustee
shall at all times satisfy the requirements of Section 310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the
Debt Securities of a particular series or Person directly or indirectly controlling, controlled by or under common control with such obligor shall serve as Trustee for the Debt Securities of such series. The Trustee shall comply with
Section 310(b) of the TIA; provided, however, that there shall be excluded from the operation of Section 310(b)(l) of the TIA this Indenture or any indenture or indentures under which other securities or certificates of
interest or participation in other securities of the Partnership are outstanding if the requirements for such exclusion set forth in Section 310(b)(l) of the TIA are met. 

Section 7.11 Preferential Collection of Claims Against the Partnership. The Trustee shall comply with Section 311(a) of the
TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the TIA to the extent indicated therein. 

Section 7.12 Compliance with Tax Laws. Notwithstanding any other provision of this Indenture, the Trustee shall be entitled to
make a deduction or withholding from any payment which it makes under this Indenture for or on account of any present or future taxes, duties or charges if and to the extent so required by any applicable law and any current or future regulations or
agreements thereunder or official interpretations thereof or any law implementing an intergovernmental approach thereto or by virtue of the relevant holder failing to satisfy any certification or other requirements in respect of the Debt Securities,
in which event the Trustee shall make such payment after such withholding or deduction has been made and shall account to the relevant authorities for the amount so withheld or deducted and shall have no obligation to gross up any payment hereunder
or pay any additional amount as a result of such withholding tax. 
 The Partnership hereby covenants with the Trustee that it will provide
the Trustee with sufficient information so as to enable the Trustee to determine whether or not the Trustee is obliged, in respect of any payments to be made by it pursuant to the Indenture, to make any withholding or deduction pursuant to an
agreement described in Section 1471(b) of the Code or otherwise imposed pursuant to Sections 1471 through 1474 of the Code and any regulations, or agreements thereunder or official interpretations thereof or any intergovernmental agreement
between the United States and another jurisdiction facilitating the implementation thereof (or any law implementing such an intergovernmental agreement).

 CONCERNING
THE HOLDERS 
 Section 8.01 Evidence of Action by Holders. Whenever in this Indenture it is provided that the Holders of a
specified percentage in aggregate principal amount of the Debt Securities of 

  
 - 42 - 








 
any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action) the fact that at the
time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in
writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of this Indenture, (c) by a combination of such instrument or instruments and any such
record of such a meeting of Holders or (d) in the case of Debt Securities evidenced by a Global Security, by any electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable
procedures. 
 Section 8.02 Proof of Execution of Instruments and of Holding of Debt Securities. Subject to the provisions of
Sections 7.01, 7.02 and 13.09, proof of the execution of any instrument by a Holder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the Trustee or in such manner as
shall be satisfactory to the Trustee. The ownership of Debt Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series. The Trustee may require such additional proof of any matter
referred to in this Section 8.02 as it shall deem necessary. 
 Section 8.03 Who May Be Deemed Owner of Debt Securities.
Prior to due presentment for registration of transfer of any Debt Security, the Partnership, the Trustee, any paying agent and any Registrar may deem and treat the Person in whose name any Debt Security shall be registered upon the books of the
Partnership as the absolute owner of such Debt Security (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment of or on account of the
principal of and premium, if any, and (subject to Section 2.12) interest on such Debt Security and for all other purposes, and none of the Partnership, the Trustee, any paying agent nor any Registrar shall be affected by any notice to the
contrary; and all such payments so made to any such Holder for the time being, or upon his order, shall be valid and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for money payable upon any such Debt
Security. 
 None of the Partnership, the Trustee, any paying agent or any Registrar will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests, or for any action taken or
any failure to act by a Depositary with respect to any Debt Securities including, without limitation, any failure of the owner of a beneficial interest in such Debt Securities to receive any payments or notices provided hereunder or for the
selection of beneficial interests in such Debt Securities to be redeemed. 
 Section 8.04 Instruments Executed by Holders Bind
Future Holders. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series
specified in this Indenture in connection with such action and subject to the following paragraph, any Holder of a Debt Security which is shown by the evidence to be included in the 

  
 - 43 - 








 
Debt Securities the Holders of which have consented to such action may, by filing written notice with the Trustee at its Corporate Trust Office and upon proof of holding as provided in
Section 8.02, revoke such action so far as concerns such Debt Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such
Debt Security and of any Debt Security issued upon transfer thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities. Any action
taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture in connection with such action shall be conclusively binding upon the Partnership, the Trustee and the Holders of
all the Debt Securities of such series. 
 The Partnership may, but shall not be obligated to, fix a record date for the purpose of
determining the Holders of Debt Securities entitled to give their consent or take any other action required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph,
those Persons who were Holders of Debt Securities at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or
not such Persons continue to be Holders of Debt Securities after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless the consent of the Holders of the percentage in aggregate principal
amount of the Debt Securities of such series specified in this Indenture shall have been received within such 120-day period.

Section 9.01 Purposes for Which Supplemental Indenture May Be Entered into Without Consent of Holders. The Partnership, when
authorized by resolutions of the Board of Directors, and the Trustee may from time to time and at any time, without the consent of Holders, enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the TIA
as in force at the date of the execution thereof) for one or more of the following purposes:

covenants are expressly being included solely for the benefit of such series) as the Board of Directors shall consider to be for the protection of the Holders of such Debt Securities, and to make the occurrence, or the occurrence and continuance, of
a Default in any of such additional covenants, restrictions, conditions or provisions a Default or an Event of Default permitting the enforcement of all or any of the several remedies provided in this Indenture; provided, that in respect of any such
additional covenant, restriction, condition or provision such supplemental Indenture may

however, that any such addition, change or elimination not otherwise permitted under this Section 9.01 shall neither apply to any Debt Security of any series created prior to the execution of such supplemental Indenture and entitled to the
benefit of such provision nor modify the rights of the Holder of any such Debt Security with respect to such provision or shall become effective only when there is no such Debt Security Outstanding; 

(k) to evidence and provide for the acceptance of appointment hereunder by a successor or separate Trustee with respect to the Debt Securities
of one or more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; and

 - 45 - 








 The Trustee is hereby authorized to join with the Partnership in the execution of any such
supplemental Indenture, to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder; provided, however, that the
Trustee shall not be obligated to enter into any such supplemental Indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 

Any supplemental Indenture authorized by the provisions of this Section 9.01 may be executed by the Partnership and the Trustee without
the consent of the Holders of any of the Debt Securities at the time Outstanding, notwithstanding any of the provisions of Section 9.02. 

Section 9.02 Modification of Indenture with Consent of Holders of Debt Securities. Without notice to any Holder but with the
consent (evidenced as provided in Section 8.01) of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such supplemental Indenture (including consents obtained in
connection with a tender offer or exchange offer for any such series of Debt Securities), the Partnership, when authorized by resolutions of the Board of Directors, and the Trustee may from time to time and at any time enter into an Indenture or
Indentures supplemental hereto (which shall conform to the provisions of the TIA as in force at the date of execution thereof) for the purpose of adding any provisions to or changing in any manner or eliminating any of the provisions of this
Indenture or of any supplemental Indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series; provided, that no such supplemental Indenture, without the consent of the Holders of each Debt Security so

 - 46 - 








 A supplemental Indenture which changes or eliminates any covenant or other provision of this
Indenture which has been expressly included solely for the benefit of one or more particular series of Debt Securities or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision,
shall be deemed not to affect the rights under this Indenture of the Holders of Debt Securities of any other series. 
 Upon the request of
the Partnership, accompanied by a copy of resolutions of the Board of Directors authorizing the execution of any such supplemental Indenture, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid, the Trustee shall
join with the Partnership in the execution of such supplemental Indenture unless such supplemental Indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its
discretion but shall not be obligated to enter into such supplemental Indenture. 
 It shall not be necessary for the consent of the Holders
under this Section 9.02 to approve the particular form of any proposed supplemental Indenture, but it shall be sufficient if such consent shall approve the substance thereof. 

After an amendment under this Section 9.02 becomes effective, the Partnership shall mail to Holders of Debt Securities of each series
affected thereby a notice briefly describing such amendment. The failure to give such notice to any such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02 with respect to other
Holders. 
 Section 9.03 Effect of Supplemental Indentures. Upon the execution of any supplemental Indenture pursuant to the
provisions of this Article IX, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the
Partnership and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of any such supplemental Indenture shall be and be deemed to
be part of the terms and conditions of this Indenture for any and all purposes. 
 The Trustee, subject to the provisions of Sections 7.01
and 7.02, shall receive, and will be fully protected in conclusively relying upon, an Officer’s Certificate and an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture and
complies with the provisions of this Article IX. 
 Section 9.04 Debt Securities May Bear Notation of Changes by Supplemental
Indentures. Debt Securities of any series authenticated and delivered after the execution of any supplemental Indenture pursuant to the provisions of this Article IX may, and shall if required by the Trustee, bear a notation in form approved by
the Trustee as to any matter provided for in such supplemental Indenture. New Debt Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of Directors, to any modification of this Indenture contained in any
such supplemental Indenture may be prepared and executed by the Partnership, authenticated by the Trustee and delivered in exchange for the Debt Securities of such series then Outstanding. Failure to make the appropriate notation or to issue a new
Debt Security of such series shall not affect the validity of such amendment. 

  
 - 47 - 








 Section 9.05 Notice of Supplemental Indentures. After any supplemental Indenture
under this Article becomes effective, the Partnership shall mail to the Holders a notice briefly describing such supplemental Indenture; provided, however, that the failure to give such notice to all Holders, or any defect therein, shall not impair
or affect the validity of such supplemental Indenture. 
 ARTICLE X 

CONSOLIDATION, MERGER, SALE OR CONVEYANCE 

Section 10.01 Consolidations and Mergers of the Partnership. The Partnership may not consolidate or amalgamate with or merge with
or into any Person, or sell, convey, transfer, lease or otherwise dispose of all or substantially all its assets to any Person, whether in a single transaction or a series of related transactions, unless: (a) either (i) the Partnership
shall be the surviving Person in the case of a merger or (ii) the resulting, surviving or transferee Person if other than the Partnership (the “Successor Company”), shall be a partnership, limited liability company or corporation
organized and existing under the laws of the United States, any State thereof or the District of Columbia and the Successor Company shall expressly assume, by an Indenture supplemental hereto, executed and delivered to the Trustee, in form
satisfactory to the Trustee, all the obligations of the Partnership under this Indenture and the Debt Securities according to their tenor; (b) immediately after giving effect to such transaction or series of transactions (and treating any Debt
which becomes an obligation of the Successor Company or any Subsidiary of the Successor Company as a result of such transaction or series of transactions as having been incurred by the Successor Company or such Subsidiary at the time of such
transaction or series of transactions), no Default or Event of Default would occur or be continuing; and (c) the Partnership shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that such
consolidation, amalgamation, merger, sale, conveyance, transfer, lease or disposition and such supplemental Indenture (if any) comply with this Indenture. 

Section 10.02 Rights and Duties of Successor Company. In case of any consolidation, amalgamation or merger where the Partnership
is not the continuing Person, or disposition of all or substantially all of the assets of the Partnership in accordance with Section 10.01, the Successor Company shall succeed to and be substituted for the Partnership with the same effect as if
it had been named herein as the respective party to this Indenture, and the predecessor entity shall be released from all liabilities and obligations under this Indenture and the Debt Securities, except that no such release will occur in the case of
a lease of all or substantially all of the assets of the Partnership. The Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of the Partnership, any or all the Debt Securities issuable hereunder
which theretofore shall not have been signed by or on behalf of the Partnership and delivered to the Trustee; and, upon the order of the Successor Company, instead of the Partnership, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any Debt Securities which previously shall have been signed and delivered by or on behalf of the Partnership to the Trustee for authentication, and any Debt Securities which the
Successor Company thereafter shall cause to be signed and 

  
 - 48 - 








 
delivered to the Trustee for that purpose. All the Debt Securities so issued shall in all respects have the same legal rank and benefit under this Indenture as the Debt Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all such Debt Securities had been issued at the date of the execution hereof. 

In case of any such consolidation, amalgamation, merger, sale or other disposition such changes in phraseology and form (but not in substance)
may be made in the Debt Securities thereafter to be issued as may be appropriate.

defeasance of Debt Securities shall be applicable to each series of Debt Securities except as otherwise specified pursuant to Section 2.03 for Debt Securities of such series. 

Section 11.02 Satisfaction and Discharge of Indenture; Defeasance. 

(a) (i) If at any time the Partnership shall have delivered to the Trustee for cancellation all Debt Securities of any series theretofore
authenticated and delivered (other than any Debt Securities of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 and Debt Securities for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Partnership as provided in Section 11.05) or (ii) all Debt Securities of such series not theretofore delivered to the Trustee for cancellation shall have become due and
payable, or are by their terms to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Partnership shall deposit with
the Trustee as trust funds money, U.S. Government Obligations or a combination thereof sufficient, as evidenced by a certificate that meets the requirements of Section 11.03(b) hereof, to pay at Stated Maturity or upon redemption all Debt
Securities of such series not theretofore delivered to the Trustee for cancellation, including principal and premium, if any, and interest due or to become due on such date of Stated Maturity or Redemption Date, as the case may be, and if in either
case the Partnership shall also pay or cause to be paid all other sums then due and payable hereunder by the Partnership with respect to the Debt Securities of such series, then this Indenture shall cease to be of further effect (except as to any
surviving rights of registration of transfer or exchange of such Debt Securities herein expressly provided for) with respect to the Debt Securities of such series, and the Partnership shall have delivered to the Trustee an Officer’s Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such Debt Securities have been complied with and the Trustee, on demand of the Partnership
accompanied by an Officer’s Certificate and an Opinion of Counsel and at the cost and expense of the Partnership, shall execute proper instruments acknowledging satisfaction of and discharging this Indenture with respect to the Debt Securities
of such series.

 (b) Subject to Sections 11.02(c), 11.03 and 11.07, the Partnership at any time may terminate,
with respect to Debt Securities of a particular series, all its obligations under the Debt Securities of such series and this Indenture with respect to the Debt Securities of such series (“Legal Defeasance Option”) or the operation of
(x) any covenant made applicable to such Debt Securities pursuant to Section 2.03 and (y) Sections 6.01(d), (g) and (h) (“Covenant Defeasance Option”). If the Partnership exercises either its Legal Defeasance
Option or its Covenant Defeasance Option with respect to Debt Securities of a particular series that are entitled to the benefit of a guarantee, the guarantee will terminate with respect to that series of Debt Securities and be automatically
released and discharged and any security that may have been granted in respect of such series shall be automatically released. The Partnership may exercise its Legal Defeasance Option notwithstanding its prior exercise of its Covenant Defeasance
Option. 
 If the Partnership exercises its Legal Defeasance Option, payment of the Debt Securities of the defeased series may not be
accelerated because of an Event of Default. If the Partnership exercises its Covenant Defeasance Option, payment of the Debt Securities of the defeased series may not be accelerated because of an Event of Default specified in Sections 6.01(d),
(g) and (h). 
 Upon satisfaction of the conditions set forth herein and upon request of the Partnership, the Trustee shall acknowledge
in writing the discharge of those obligations that the Partnership terminates. 
 (c) Notwithstanding clauses (a) and (b) above,
the Partnership’s obligations in Sections 2.07, 2.09, 4.02, 4.04, the last sentence of 4.05(a), 4.06(a), 5.01, 7.06, 11.05, 11.06 and 11.07 shall survive until the Debt Securities of the defeased series have been paid in full. Thereafter, the
Partnership’s obligations in Sections 7.06, 11.05 and 11.06 shall survive. 
 Section 11.03 Conditions of Defeasance. The
Partnership may exercise its Legal Defeasance Option or its Covenant Defeasance Option with respect to Debt Securities of a particular series only if: 

(a) the Partnership irrevocably deposits in trust with the Trustee money, U.S. Government Obligations or a combination thereof for the payment
of principal of, and premium, if any, and interest on, the Debt Securities of such series to Stated Maturity or redemption, as the case may be; 

(b) the Partnership delivers to the Trustee a certificate (which shall not be subject to the requirements of Section 13.05) from a
nationally recognized firm of independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment
will provide cash at such times and in such amounts as will be sufficient to pay the principal, premium, if any, and interest when due on all the Debt Securities of such series to Stated Maturity or redemption, as the case may be; 

(c) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(e) or (f) with respect
to the Partnership occurs which is continuing at the end of the period; 

  
 - 50 - 








 (d) no Default has occurred and is continuing on the date of such deposit and after giving effect
thereto; 
 (e) the deposit does not constitute a default under any other material agreement binding on the Partnership; 

(f) the Partnership delivers to the Trustee an Opinion of Counsel to the effect that the trust resulting from the deposit does not constitute,
or is qualified as, a regulated investment company under the Investment Company Act of 1940; 
 (g) in the event of the Legal Defeasance
Option, the Partnership shall have delivered to the Trustee an Opinion of Counsel stating that the Partnership has received from, or there has been published by, the Internal Revenue Service a ruling, or since the date of this Indenture there has
been a change in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of Debt Securities of such series will not recognize income, gain or loss for
federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit, defeasance and
discharge had not occurred; 
 (h) in the event of the Covenant Defeasance Option, the Partnership shall have delivered to the Trustee an
Opinion of Counsel to the effect that the Holders of Debt Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit, defeasance and discharge and will be subject to federal income
tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit, defeasance and discharge had not occurred; and 

(i) the Partnership delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance and discharge of the Debt Securities of such series as contemplated by this Article XI have been complied with. 

Before or after a deposit, the Partnership may make arrangements satisfactory to the Trustee for the redemption of Debt Securities of such
series at a future date in accordance with Article III. 
 Section 11.04 Application of Trust Money. The Trustee shall hold in
trust money or U.S. Government Obligations deposited with it pursuant to this Article XI. It shall apply the deposited money and the money from U.S. Government Obligations through any paying agent and in accordance with this Indenture to the payment
of principal of, and premium, if any, and interest on, the Debt Securities of the defeased series. 
 Section 11.05 Repayment to
Partnership. The Trustee and any paying agent shall promptly turn over to the Partnership, upon receipt of a Partnership Request, any excess money or securities (including U.S. Government Obligations) held by them at any time, which, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written certification (which shall not be subject to the requirements of Section 13.05) thereof delivered to the Trustee (which may be the opinion
delivered under Section 11.03(b) hereof) are in excess of the amount thereof that would then be required to be deposited to effect a Legal Defeasance Option or Covenant Defeasance Option. 

  
 - 51 - 








 Subject to any applicable abandoned property law, the Trustee and any paying agent shall pay to
the Partnership upon request any money held by them for the payment of principal, premium or interest that remains unclaimed for two years, and, thereafter, Holders entitled to such money must look to the Partnership for payment as general
creditors. 
 Section 11.06 Indemnity for U.S. Government Obligations. The Partnership shall pay and shall indemnify the Trustee
and the Holders against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 

Section 11.07 Reinstatement. If the Trustee or any paying agent is unable to apply any money or U.S. Government Obligations in
accordance with this Article XI by reason of any legal proceeding or by reason of any order or judgment of any court or government authority enjoining, restraining or otherwise prohibiting such application, the Partnership’s obligations under
this Indenture and the Debt Securities of the defeased series shall be revived and reinstated as though no deposit had occurred pursuant to this Article XI until such time as the Trustee or any paying agent is permitted to apply all such money or
U.S. Government Obligations in accordance with this Article XI.
