through the facilities of a Depositary) by such Holders in person or by an agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered
(either physically or by means of a facsimile or an electronic transmission, provided that such electronic transmission is transmitted through the facilities of a Depositary) to the Trustee and, where it is hereby expressly required, to the
Partnership. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such

 The Partnership may, in the circumstances permitted by the Trust Indenture Act, set any day
as the record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this
Indenture to be given or taken by Holders of Securities of such series. With regard to any record date set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date (or their duly appointed agents),
and only such Persons, shall be entitled to give or take the relevant action, whether or not such Holders remain Holders after such record date. With regard to any action that may be given or taken hereunder only by Holders of a requisite principal
amount of Outstanding Securities of any series (or their duly appointed agents) and for which a record date is set pursuant to this paragraph, the Partnership may, at its option, set an expiration date after which no such action purported to be
given or taken by any Holder shall be effective hereunder unless given or taken on or prior to such expiration date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date (or their duly appointed
agents). On or prior to any expiration date set pursuant to this paragraph, the Partnership may, on one or more occasions at its option, extend such date to any later date. Promptly after setting such record date or expiration date, or extension
thereof, the Partnership shall notify in writing the Trustee and the Holder of Outstanding Securities of such series of any record date or expiration date, or extension thereof, so fixed. Nothing in this paragraph shall prevent any Holder (or any
duly appointed agent thereof) from giving or taking, after any such expiration date, any action identical to, or, at any time, contrary to or different from, the action or purported action to which such expiration date relates, in which event the
Partnership may set a record date in respect thereof pursuant to this paragraph. Nothing in this paragraph shall be construed to render ineffective any action taken at any time by the Holders (or their duly appointed agents) of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is so taken. Notwithstanding the foregoing or the Trust Indenture Act, the Partnership shall not set a record date for, and the provisions of this paragraph
shall not apply with respect to, any notice, declaration or direction referred to in the next paragraph. 
 The Trustee may set any day as a
record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default, (ii) any declaration of acceleration referred to in Section 5.02, if
an Event of Default with respect to Securities of such series has occurred and is continuing and the Trustee shall not have given such a declaration to the Partnership, (iii) any request to institute proceedings referred to in
Section 5.07(2) or (iv) any direction referred to in Section 5.12, in each case with respect to Securities of such series. Promptly after any record date is set pursuant to this paragraph, the Trustee shall notify in writing the
Partnership and the Holders of Outstanding Securities of such series of any such record date so fixed and the proposed action. The Holders of Outstanding Securities of such series on such record date (or their duly appointed agents), and only such
Persons, shall be entitled to join in such notice, declaration or direction, whether or not such Holders remain Holders after such record date; provided that, unless such notice, declaration or direction shall have become effective by virtue of
Holders of the requisite principal amount of Outstanding Securities of such series on such record date (or their duly appointed agents) having joined therein on or prior to the 90th day after such record date, such notice, declaration or direction
shall automatically and without any action by any Person be cancelled and of no further effect. Nothing in this paragraph shall be construed to prevent a Holder (or a duly appointed agent thereof) from giving, before or after the expiration of such 90-day period, a notice, declaration or direction contrary to or different from, or, after the expiration of such period, identical to, the notice, declaration or direction to which such record date relates, in
which event a new record date in respect thereof shall be set pursuant to this paragraph. Nothing in this paragraph shall be construed to render ineffective any notice, declaration or direction of the type referred to in this paragraph given at any
time to the Trustee and the Partnership by Holders (or their duly appointed agents) of the requisite principal amount of Outstanding Securities of the relevant series on the date such notice, declaration or direction is so given. 

  
 12 













 Without limiting the foregoing, a Holder entitled hereunder to give or take any action
hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any
different part of such principal amount. 
 Section 1.05 Notices, Etc., to Trustee and
Partnership. 
 Any request, demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or
permitted by this Indenture to be made upon, given or furnished to, or filed with; 
 (1) the Trustee by any Holder or by the Partnership
shall be sufficient for every purpose hereunder if made, given, furnished or filed in writing (which may be via facsimile) to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department, or at any other address
previously furnished in writing by the Trustee, or 
 (2) the Partnership by the Trustee or by any Holder shall be sufficient for every
purpose hereunder (unless otherwise herein expressly provided) if in writing (which may be via facsimile) and mailed, first-class postage prepaid, to the Partnership addressed to it at One Greenway Plaza, Suite 600, Houston, Texas 77046, to the
attention of the Corporate Secretary, or at any other address previously furnished in writing to the Trustee by the Partnership. 
 
Section 1.06 Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice
shall be sufficiently given (unless otherwise herein expressly provided) if in writing and mailed, first-class postage prepaid (if international mail, by air mail), to each Holder affected by such event, at his address as it appears in the Security
Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any
defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Any notice mailed to a Holder in the manner herein prescribed shall be conclusively deemed to have been received by
such Holder, whether or not such Holder actually receives such notice. 
 Where this Indenture provides for notice in any manner, such
notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing
shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension
of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose
hereunder. 
 Section 1.07 Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act that is required under such Act to be a
part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the latter provision shall be deemed to
apply to this Indenture as so modified 

  
 13 













 
or excluded, as the case may be. Wherever this Indenture refers to a provision of the Trust Indenture Act, such provision is incorporated by reference in and made a part of this Indenture. All
terms used in this Indenture that are defined by the Trust Indenture Act, defined by the Trust Indenture Act referenced to another statute or defined by any rule of the Commission and not otherwise defined herein shall have the meanings ascribed to
them thereby.

[CUSIP No.                 ] 

BUCKEYE PARTNERS, L.P., a Delaware limited partnership (herein called the “Partnership”, which term includes any successor Person
under the Indenture hereinafter referred to), for value received, hereby promises to pay to                     , or registered assigns, the
principal sum of                     United States Dollars on
                     [if the Security is to bear interest prior to Maturity, insert—, and to pay interest thereon
from                     , or from the most recent Interest Payment Date to which interest has been paid or duly provided for, semi-annually on
                     and                      in
each year, commencing, at the rate of     % per annum, until the principal hereof is paid or made available for payment [if applicable, insert—        , and at the rate of
    % per annum on any overdue principal and premium and on any overdue installment of interest]. [If applicable, insert—The amount of interest payable for any period shall be computed on the basis of twelve 30-day months and a 360-day year. The amount of interest payable for any partial period shall be computed on the basis of a 360-day
year of twelve 30-day months and the days elapsed in any partial month.] In the event that any date on which interest is payable on this Security is not a Business Day, then a payment of the interest payable
on such date will be made on the next succeeding day which is a Business Day (and without any interest or other payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable. A
“Business Day” shall mean, when used with respect to any Place of Payment, each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in that Place of Payment are authorized or obligated by law,
executive order or regulation to close. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more
Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the
                or                 (whether or not a Business Day), as the case may be,
next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Security
(or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not
less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which the Securities of this series may be
listed or traded, and upon such notice as may be required by such exchange or automated quotation system, all as more fully provided in such Indenture]. 

[If the Security is not to bear interest prior to Maturity, insert— 

The principal of this Security shall not bear interest except in the case of a default in payment of principal upon acceleration, upon
redemption or at Stated Maturity and in such case the overdue principal of this Security shall bear interest at the rate of % per annum, which shall accrue from the date of such default in payment to the date payment of such principal has been made
or duly provided for. Interest on 

  
 16 













 
any overdue principal shall be payable on demand. Any such interest on any overdue principal that is not so paid on demand shall bear interest at the rate of     % per annum,
which shall accrue from the date of such demand for payment to the date payment of such interest has been made or duly provided for, and such interest shall also be payable on demand.] 

[If a Global Security, insert — Payment of the principal of [(and premium, if any)] and [if applicable, insert — any such] interest
on this Security will be made by transfer of immediately available funds to a bank account in the United States of America designated by the Holder in such coin or currency of the United States of America as at the time of payment is legal tender
for payment of public and private debts [state other currency].] 
 [If a Definitive Security, insert — Payment of the principal of
[(and premium, if any)] and [if applicable, insert — any such] interest on this Security will be made at the office or agency of the Partnership maintained for that purpose in, [in such coin or currency of the United States of America as at the
time of payment is legal tender for payment of public and private debts] [state other currency] [or subject to any laws or regulations applicable thereto and to the right of the Partnership (as provided in the Indenture) to rescind the designation
of any such Paying Agent, at the [main] offices of                      in
                     and                      in
                    , or at such other offices or agencies as the Partnership may designate, by [United States Dollar] [state other currency] check
drawn on, or transfer to a [United States Dollar] account maintained by the payee with, a bank in The City of New York (so long as the applicable Paying Agent has received proper transfer instructions in writing at least     
days prior to the payment date)] [if applicable, insert —; provided, however, that payment of interest may be made at the option of the Partnership by [United States Dollar] [state other currency] check mailed to the addresses of the Persons
entitled thereto as such addresses shall appear in the Security Register] [or by transfer to a [United States Dollar] [state other currency] account maintained by the payee with a bank in The City of New York [state other Place of Payment] (so long
as the applicable Paying Agent has received proper transfer instructions in writing by the Record Date prior to the applicable Interest Payment Date)].] 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for all
purposes have the same effect as if set forth at this place. 
 Unless the certificate of authentication hereon has been executed by the
Trustee by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 

IN WITNESS WHEREOF, the Partnership has caused this instrument to be duly executed.

instituted by the Holder of this Security for the enforcement of any payment of principal hereof or [any premium or] interest hereon on or after the respective due dates expressed herein. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the

his attorney duly authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.]

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

No service charge shall be made for any such registration of transfer or exchange, but the Partnership may require payment of a sum sufficient

or before the initial issuance of the Securities of such series shall be incorporated herein by reference with respect to Securities of such series and shall thereafter be deemed to be a part of the Indenture for all purposes relating to Securities
of such series as fully as if such Board Resolution or Officers’ Certificate were set forth herein in full. 
 All Securities of any
one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the Holders, for increases in the aggregate principal amount of such series of Securities and issuances of additional
Securities of such series or for the establishment of additional terms with respect to the Securities of such series. If any of the terms of the series are established by action taken by or pursuant to a Board Resolution, a copy of an appropriate
record of such action shall be certified by an authorized officer or other authorized person of the General Partner on behalf of the Partnership and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting

Section 3.03 Execution, Authentication, Delivery and Dating. 

The Securities shall be executed on behalf of the Partnership by the Chairman of the Board, Vice Chairman, Chief Executive Officer, President,
Chief Financial Officer, or any Vice President of the General Partner and need not be attested. The signature of any of these officers on the Securities may be manual or facsimile. Securities bearing the manual or facsimile signatures of individuals
who were at any 

  
 25 













 
time the proper officers of the General Partner shall bind the Partnership, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to time after the
execution and delivery of this Indenture, the Partnership may deliver Securities of any Series executed by the Partnership to the Trustee for authentication, together with a Partnership Order for the authentication and delivery of such Securities,
and the Trustee in accordance with the Partnership Order shall authenticate and deliver such Securities; provided, however, that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and deliver such Securities
from time to time in accordance with such other procedures (including, without limitation, the receipt by the Trustee of oral or electronic instructions from the Partnership or its duly authorized agents, thereafter promptly confirmed in writing)
acceptable to the Trustee as may be specified by or pursuant to a Partnership Order delivered to the Trustee prior to the time of the first authentication of Securities of such series. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by Sections 2.01 and 3.01, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the
Trustee shall be entitled to receive, in addition to any Officers’ Certificate and Opinion of Counsel required to be furnished to the Trustee pursuant to Section 1.02, and (subject to Section 6.01) shall be fully protected in relying
upon, an Opinion of Counsel stating, 
 (1) The form and terms (or the manner of determining the terms) of such Securities have been
established by or pursuant to Board Resolution as permitted by Section 2.01, that such form or forms have been established in conformity with the provisions of this Indenture; 

(2) if the terms of such Securities have been, or in the case of Securities of a series offered in a Periodic Offering, will be, established
by or pursuant to a Board Resolution as permitted by Section 3.01, that such terms have been, or in the case of Securities of a series offered in a Periodic Offering, will be, established in conformity with the provisions of this Indenture,
subject, in the case of Securities of a series offered in a Periodic Offering, to any conditions specified in such Opinion of Counsel (which conditions are reasonably acceptable to the Trustee); 

(3) that such 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, which conditions are reasonably acceptable to the Trustee, will constitute valid and legally binding obligations of the Partnership enforceable in accordance with their terms, subject to bankruptcy,
insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles and entitled to the benefits of this Indenture, equally and
ratably with all other Securities, if any, of such Series Outstanding; and 
 (4) such other matters as the Trustee may reasonably request;
and if the authentication and delivery relates to a new series of Securities created by an indenture supplemental hereto, also stating that all conditions precedent to the execution of the supplemental indenture with respect to that series of
Securities have been complied with, the Partnership has the power to execute and deliver any such supplemental indenture and has taken all necessary action for those purposes and any such supplemental indenture has been executed and delivered and
constitutes the legal, valid and binding obligation of the Partnership enforceable in accordance with its terms (subject, as to enforcement of remedies, to applicable bankruptcy, reorganization, insolvency, fraudulent conveyance, moratorium or other
laws and legal principles affecting creditors’ rights generally from time to time in effect and to general equitable principles, whether applied in an action at law or in equity). 

  
 26 













 If such form or forms or terms have been so established, the Trustee shall not be required
to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee. 
 Notwithstanding the provisions of Section 3.01 and of the preceding paragraph, if all Securities of a
series are not to be originally issued at one time, it shall not be necessary to deliver the Officers’ Certificate otherwise required pursuant to Section 3.01 or the Partnership Order and Opinion of Counsel or Board Resolution or
supplemental indenture otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original issuance of the
first Security of such series to be issued. 
 With respect to Securities of a series not to be originally issued at one time, the Trustee
may rely upon the Opinion of Counsel and the other documents delivered pursuant to Sections 2.01 and 3.01 and this Section, as applicable, in connection with the first authentication of Securities of such series and any subsequent request by
the Partnership to the Trustee to authenticate 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 Officers’
Certificate shall be true and correct as if made on such date. 
 Each Security shall be dated the date of its authentication. 

No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such
Security a certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized signatory, and such certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Partnership, and the Partnership
shall deliver such Security to the Trustee for cancellation as provided in Section 3.09 for all purposes of this Indenture, such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to
the benefits of this Indenture. 
 Section 3.04 Temporary Securities. 

Pending the preparation of Definitive Securities of any series, the Partnership may execute, and upon receipt of the documents required by
Section 3.03, together with a Partnership Order, the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of
the tenor of the Definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of
such Securities. 
 If temporary Securities of any series are issued, the Partnership will cause Definitive Securities of that series to be
prepared without unreasonable delay. After the preparation of Definitive Securities of such series, the temporary Securities of such series shall be exchangeable for Definitive Securities of such series upon surrender of the temporary Securities of
such series at the office or agency of the Partnership maintained pursuant to Section 10.02 for the purpose of exchanges of Securities of such series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary
Securities of any series the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor one or more Definitive Securities of the same series, of any authorized denominations and of a like aggregate principal amount
and tenor. Until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities of such series and tenor. 

  
 27 













 Section 3.05 Registration, Registration of Transfer
and Exchange. 
 The Partnership shall cause to be kept at an office or agency of the Security Registrar in The City of New York a
register (the register maintained in such office or in any other office or agency of the Partnership in a Place of Payment being herein sometimes referred to as the “Security Register”) in which, subject to such reasonable regulations as
it may prescribe, the Partnership shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed as the initial “Security Registrar” for the purpose of registering Securities and transfers
of Securities as herein provided and its corporate trust office which, at the date hereof, is located at [Trustee’s Address], as the initial office or agency in The City of New York where the Security Register will be maintained. The
Partnership may at any time replace such Security Registrar, change such office or agency or act as its own Security Registrar. The Partnership will give prompt written notice to the Trustee of any change of the Security Registrar or of the location
of such office or agency. At all reasonable times the Security Register shall be available for inspection by the Trustee. 
 Upon surrender
for registration of transfer of any Security of any series at the office or agency of the Partnership maintained pursuant to Section 10.02 for such purpose, the Partnership shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of a like aggregate principal amount and tenor. 

At the option of the Holder, Securities of any series (except a Global Security) may be exchanged for other Securities of the same series, of
any authorized denominations and of a like aggregate principal amount and tenor, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so surrendered for exchange, the Partnership shall execute, and
the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities
issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Partnership, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such
registration of transfer or exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so
required by the Partnership or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Partnership and the Security Registrar duly executed, by the Holder thereof or his attorney duly
authorized in writing. 
 No service charge shall be made for any registration of transfer or exchange of Securities, but the Partnership
may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.04 or 11.07 not
involving any transfer. Neither the Trustee nor the Partnership shall be required (1) to issue, register the transfer of or exchange Securities of any series (or of any series and specified tenor, as the case may be) during a period beginning
at the opening of business 15 days before the day of mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.03 and ending at the close of business on the day of such mailing, or (2) to
register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

Notwithstanding any other provision in this Indenture, no Global Security may be transferred to, or registered or exchanged for Securities
registered in the name of, any Person other than the Depositary for such Global Security or any nominee thereof, and no such transfer may be registered, unless (1) such Depositary (A) notifies the Partnership that it is unwilling or unable
to continue as Depositary for such 

  
 28 













 
Global Security or (B) has ceased to be a clearing agency registered under the Exchange Act, (2) the Partnership executes and delivers to the Trustee a Partnership order that such
Global Security shall be so transferred, registrable and exchangeable, and such transfers shall be registrable, (3) there shall have occurred and be continuing an Event of Default with respect to the Securities evidenced by such Global Security
or (4) there shall exist such other circumstances, if any, as have been specified for this purpose as contemplated by Section 3.01. Notwithstanding any other provision in this Indenture, a Global Security to which the restriction set forth
in the preceding sentence shall have ceased to apply may be transferred only to, and may be registered and exchanged for Securities registered only in the name or names of, such Person or Persons as the Depositary for such Global Security shall have
directed and no transfer thereof other than such a transfer may be registered. 
 Every Security authenticated and delivered upon
registration of transfer of, or in exchange for or in lieu of, a Global Security to which the restriction set forth in the first sentence of the preceding paragraph shall apply, whether pursuant to this Section, Section 3.04, 3.06, 9.06 or
11.07 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security. 

Section 3.06 Mutilated, Destroyed, Lost and Stolen Securities. 

If any mutilated Security is surrendered to the Trustee, together with such security or indemnity as may be required by the Partnership or the
Trustee to save each of them and any agent of either of them harmless, the Partnership shall execute and upon its request the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and
principal amount and bearing a number not contemporaneously Outstanding. 
 If there shall be delivered to the Partnership and the Trustee
(1) evidence to their satisfaction of the destruction, loss or theft of any Security and (2) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of
notice to the Partnership or the Trustee that such Security has been acquired by a bona fide purchaser, the Partnership shall execute and upon its request the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen
Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously Outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Partnership in its
discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this Section, the
Partnership may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. Every new
Security of any series issued pursuant to this Section in exchange for any mutilated Security or in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Partnership, whether or not the
mutilated, destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder.

 The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities.

 Section 3.07 Payment of Interest; Interest Rights
Preserved. 
 Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, interest on
any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the
Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular 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 (1) or (2) below: 
 (1) The Partnership may elect to make
payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) 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 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 prepaid, to
each Holder of Securities of such series at his address as it appears in the 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 Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no
longer be payable pursuant to the following Clause (2). 
 (2) The Partnership may make payment of any Defaulted Interest on the Securities
of any series in any other lawful manner not inconsistent with the requirements of any securities exchange or automated quotation system on which such Securities may be listed or traded, and upon such notice as may be required by such exchange, if,
after written 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. 

Subject to the foregoing provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security, shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

Section 3.08 Persons Deemed Owners. 

Except as otherwise provided as contemplated by Section 3.01 with respect to any series of Securities, prior to due presentment of a
Security for registration of transfer, the Partnership, the Trustee and any agent of the Partnership or the Trustee may treat the Person in whose name such Security is 

  
 30 













 
registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to Section 3.07) any interest on such Security and for all other
purposes whatsoever, whether or not such Security is overdue, and neither the Partnership, the Trustee nor any agent of the Partnership or the Trustee shall be affected by notice to the contrary. 

No holder of any beneficial interest in any Global Security held on its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary may be treated by the Partnership, the Trustee and any agent of the Partnership or the Trustee as the owner of such Global Security for all purposes whatsoever. None of the Partnership, the
Trustee nor 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 beneficial ownership interests of a Global Security or for maintaining,
supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 3.09
Cancellation. 
 All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Partnership may at any time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Partnership may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated
hereunder which the Partnership has not issued and sold, and all Securities so delivered shall be promptly cancelled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this
Section, except as expressly permitted by this Indenture. All cancelled Securities held by the Trustee shall be disposed of in accordance with its customary procedures, and the Trustee shall thereafter deliver to the Partnership a certificate with
respect to such disposition. 
 Section 3.10 Computation of Interest. 

Except as otherwise specified as contemplated by Section 3.01 for Securities of any series, interest on the Securities of each series
shall be computed on the basis of a 360-day year of twelve 30-day months. 

Section 3.11 CUSIP Numbers. 

The Partnership in issuing the Securities may use “CUSIP” numbers (in addition to the other identification numbers printed on the
Securities), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of such
“CUSIP” numbers either as printed on the 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 Securities, and any such redemption shall not be
affected by any defect in or omission of such “CUSIP” numbers. The Partnership will promptly notify the Trustee in writing of any change in the “CUSIP” numbers.

Section 5.02 Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of (or, if any of the Securities of that series are Original Issue Discount Securities, such portion of the
principal amount of such Securities as may be specified in the terms thereof), and accrued but unpaid interest, if any, on all of the Securities of that series to be due and payable immediately, by a notice in writing to the Partnership (and to the
Trustee if given by Holders), and upon any such declaration such principal amount (or specified amount) shall become immediately due and payable. 

At any time after such a declaration of acceleration with respect to Securities of any series has been made and before a judgment or decree
for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to the Partnership and the Trustee,
may rescind and annul such declaration and its consequences if

sufficient to pay 
 (a) all overdue interest on all Securities of that series, 

(b) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such declaration of
acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 
 (c) to the extent that payment of
such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities, and 
 (d) all sums
paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 

  
 34 













 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 

No such rescission shall affect any subsequent Default or impair any right consequent thereon. 

Section 5.03 Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Partnership covenants that if 

(1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a
period of 30 days, or 
 (2) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity
thereof, the Partnership will, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount then due and payable on such Securities for principal and any premium and interest and, to the extent
that payment of such interest shall be legally enforceable, interest on any overdue principal and premium and on any overdue interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as
shall be sufficient to cover the reasonable costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel. 

If an Event of Default with respect to Securities of any series occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights, whether for the specific enforcement of any
covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 
Section 5.04 Trustee May File Proofs of Claim. 
 In case of any judicial proceeding relative to the Partnership or any
other obligor upon the Securities, their property or their creditors, the Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have
claims of the Holders and the Trustee allowed in any such proceeding. In particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any
custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to
the making of such payments directly to the Holders, to pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under
Section 6.07. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt
on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding;
provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar committee.

 Section 5.05 Trustee May Enforce Claims Without
Possession of Securities. 
 All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by

recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which
such judgment has been recovered.

surrender thereof if fully paid: 
 FIRST: To the payment of all amounts due the Trustee under Section 6.07; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities in respect of which

THIRD: The balance, if any, to the Partnership. 

Section 5.07 Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless 
 (1) such Holder has previously
given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 
 (2) the Holders of
not less than a majority in principal amount of the Outstanding Securities of that series shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 

(3) such Holder or Holders have offered and, if requested, provided to the Trustee security or indemnity satisfactory to it against the costs,
expenses and liabilities to be incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice,
request and offer and, if requested, provision of security or indemnity has failed to institute any such proceeding; and 
 (5) no direction
inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 

  
 36 













 it being understood and intended that no one or more of such Holders shall have any right in any manner
whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce
any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 
 
Section 5.08 Unconditional Right of Holders to Receive Principal, Premium and Interest. 
 Notwithstanding any other
provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 3.07) interest on such Security on the respective
Stated Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 

Section 5.09 Restoration of Rights and Remedies. 

If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every such case, subject to any determination in such proceeding, the Partnership, the Trustee and the Holders shall be restored
severally and respectively to their former positions hereunder, and thereafter all rights and remedies of the Trustee and the Holders shall continue as though no such proceeding had been instituted. 

Section 5.10 Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 3.06, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy. 
 Section 5.11 Delay or Omission
Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any
Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time
to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 

Section 5.12 Control by Holders. 

The Holders of a majority in aggregate principal amount of the Outstanding Securities of any series shall have the right to direct the time,
method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided, however, that 

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

  
 37 













 (2) the Trustee may take any other action deemed proper by the Trustee which is not
inconsistent with such direction; and 
 (3) subject to the provisions of Section 6.01, the Trustee shall have the right to decline to
follow any such direction if the Trustee in good faith shall determine that the proceeding so directed would involve the Trustee in personal liability or would otherwise be contrary to applicable law. 

Section 5.13 Waiver of Past Defaults. 

The Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of any series may on behalf of the Holders
of all the Securities of such series waive any past default hereunder with respect to such series and its consequences, except 
 (1) a
continuing default in the payment of the principal of or any premium or interest on any Security of such series, or 
 (2) a default in
respect of a covenant or provision hereof which under Article IX cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 

Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for
every purpose of this Indenture, but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon. 

Section 5.14 Undertaking for Costs. 

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, suffered
or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust
Indenture Act; provided, that neither this Section nor the Trust Indenture Act shall 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 10% of principal amount
of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of principal of (or premium, if any) or interest on any Security held by such Holder on or after the respective Stated Maturities
expressed by such Security (or, in the case of redemption or repayment, on or after the Redemption Date); and provided, further, that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an
undertaking or to make such an assessment in any suit instituted by the Partnership. 
 Section 5.15
Waiver of Usury, Stay or Extension Laws. 
 The Partnership covenants (to the extent that it may lawfully do so) that it will not at
any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of
this Indenture; and the Partnership (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the
Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Section 6.01 Certain Duties and Responsibilities. 
 (1) If an Event of Default has occurred and is continuing, the Trustee

which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they substantially conform to the requirements of this Indenture (but need not

(d) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in

assured to it.

relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

(4) the Trustee may consult with counsel and the written advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon; 

(5) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or

such request or direction; 
 (6) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, notice, request, direction, consent, order, bond, debenture, or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or
matters as it may see fit and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Partnership, personally or by agent or attorney at the sole cost of

any such certificate previously delivered and not superseded;

(10) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act hereunder. 

Section 6.04 Individual Rights of Trustee. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Partnership, in its individual or
any other capacity, may become the owner or pledgee of Securities and, subject to Sections 6.09 and 6.14, may otherwise deal with the Partnership with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent,
Security Registrar or such other agent. 
 Section 6.05 Money Held in Trust. 

Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall

 Within 60 days after each February 15 beginning with the
February 15 following the date of this Indenture, the Trustee shall mail to each Holder a brief report dated as of such February 15 that complies with Trust Indenture Act Section 313(a) if such report is required by such Trust
Indenture Act Section 313(a). The Trustee also shall comply with Trust Indenture Act Sections 313(b) and 313(c). 
 The

 Section 6.07 Compensation and Indemnity. 

The Partnership agrees: 
 (1) to
pay to the Trustee from time to time reasonable and customary compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust),
which compensation may be set forth in a separate Letter Agreement between the Partnership and the Trustee; 
 (2) to reimburse the Trustee
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to its gross negligence or bad faith; and 
 (3) to
indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence, willful misconduct or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust
or trusts hereunder, including the reasonable costs and expenses of defending itself against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. The Trustee shall notify the Partnership

The Partnership need not reimburse any expense or indemnify against any loss or liability to the extent incurred by the Trustee as determined by a court of competent jurisdiction to have been caused by its own gross negligence, bad faith or willful
misconduct. 
 The obligations of the Partnership under this Section to compensate the Trustee and to pay or reimburse the Trustee for
expenses, disbursements and advances shall constitute additional indebtedness hereunder. Without limiting any rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of
Default specified in Section 5.01(5) or Section 5.01(6), the expenses (including the reasonable charges and expenses of its counsel) and the compensation for such services are intended to constitute expenses of administration under any
applicable Bankruptcy Law. 
 The Partnership’s obligations under this Section 6.07 and any lien arising hereunder shall survive
the resignation or removal of the Trustee, the discharge of the Partnership’s obligations pursuant to Article IV of this Indenture and any rejection or termination of this Indenture under any Bankruptcy Law. 

Section 6.08 Disqualification; Conflicting Interests. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate
such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. 

  
 42 













 Section 6.09 Corporate Trustee Required;
Eligibility. 
 There shall at all times be one or more Trustees hereunder with respect to the Securities of each series, at least one
of which shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such and has a combined capital and surplus required by the Trust Indenture Act. If such Person publishes reports of condition at least annually, pursuant to
law or to the requirements of a supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report
of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 

Section 6.10 Resignation and Removal; Appointment of Successor. 

No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 6.11. 
 The Trustee may
resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Partnership. If the instrument of acceptance by a successor Trustee required by Section 6.11 shall not have been delivered to the
Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of
the Outstanding Securities of such series, delivered to the Trustee and to the Partnership. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of removal,
the removed Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. 
 If at any time: 

(1) the Trustee shall fail to comply with Section 6.08 after written request therefor by the Partnership or by any Holder who has been a
bona fide Holder of a Security for at least six months, or 
 (2) the Trustee shall cease to be eligible under Section 6.09 and shall
fail to resign after written request therefor by the Partnership or by any such Holder, or 
 (3) the Trustee shall become incapable of
acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (A) the Partnership, acting pursuant to the authority of a Board Resolution, may remove the Trustee with respect to all Securities, or (B) subject to Section 5.14, any Holder who
has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the
appointment of a successor Trustee or Trustees. 
 If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy
shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the Partnership, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those
series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only 

  
 43 













 
one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such resignation, removal or
incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to
the Partnership and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor Trustee with respect to
the Securities of such series and to that extent supersede the successor Trustee appointed by the Partnership. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Partnership or the Holders and
accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Partnership shall
give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series to all Holders of Securities of such series in the
manner provided in Section 1.06. 
 Each notice shall include the name of the successor Trustee with respect to the Securities of such
series and the address of its Corporate Trust Office. 
 Section 6.11 Acceptance of Appointment by
Successor. 
 (1) In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such successor
Trustee so appointed shall execute, acknowledge and deliver to the Partnership and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Partnership or the successor Trustee, such retiring Trustee shall,
upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder. 
 (2) In case of the appointment hereunder of a successor Trustee with respect to the
Securities of one or more (but not all) series, the Partnership, the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture supplemental hereto wherein each successor
Trustee shall accept such appointment and which (A) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (B) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be
deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee, and (C) 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 as co-trustees of the same trust and that each such 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; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein
and each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, 

  
 44 













 
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, but, on request of the
Partnership or any successor Trustee, such retiring Trustee shall, upon payment of its charges, duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities
of that or those series to which the appointment of such successor Trustee relates. 
 (3) Upon request of any such successor Trustee, the
Partnership shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in paragraph (1) or (2) of this Section, as the case may be. 

(4) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 Section 6.12 Merger, Conversion, Consolidation or Succession to
Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation
resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated,
but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor
Trustee had itself authenticated such Securities. 
 Section 6.13 Preferential Collection of Claims
Against Partnership. 
 If and when the Trustee shall be or become a creditor of the Partnership or any other obligor upon the
Securities, the Trustee shall be subject to the provisions of the Trust Indenture Act regarding the collection of claims against the Partnership or any such other obligor. 

Section 6.14 Appointment of Authenticating Agent. 

The Trustee (upon notice to the Partnership) may appoint an Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series issued upon original issue (in accordance with procedures acceptable to the Trustee) and upon exchange, registration of transfer or partial
redemption thereof or pursuant to Section 3.06, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever
reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee
by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Partnership and shall at all times be a corporation organized and doing
business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to
supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be
eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section. 

  
 45 













 Any corporation into which an Authenticating Agent may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate
trust business of such Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the
Trustee or such Authenticating Agent. 
 An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and
to the Partnership. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Partnership. Upon receiving such a notice of resignation or upon such a
termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Partnership. Any
successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor
Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 
 Except with respect to an Authenticating
Agent appointed at the request of the Partnership, the Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section. 

If an appointment with respect to one or more series is made pursuant to this Section, the Securities of such series may have endorsed
thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Trustee is for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including the Partnership’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

made shall succeed to, and be substituted for, and may exercise every right and power of, the Partnership under this Indenture with the same effect as if such successor Person had been named originally as the Partnership herein. When a successor
Person duly assumes all of the obligations of the Partnership pursuant hereto and pursuant to the Securities, the predecessor shall be relieved of the performance and observance of all obligations and covenants of this Indenture and the Securities,
including but not limited to the obligation to make payment of the principal of and interest, if any, on all the Securities then outstanding, and the Partnership may thereupon or any time thereafter be liquidated and dissolved.

of, this Indenture, or modifying in any manner the rights of the Holders of Securities of such series under this Indenture; provided, however, that no such supplemental indenture shall, without the consent of the Holder of each Outstanding Security
affected thereby, 

  
 49

interest on, any Security, or reduce the principal amount thereof or premium, if any, on or the rate of interest or the method of computation of interest;

respect to changes in the references to “the Trustee” and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of Sections 6.11 and 9.01(9). 

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included
solely for the benefit of one or more particular series of Securities, or which modifies the rights of the Holders of 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 Securities of any other series. 
 It shall not be necessary for any Act of Holders under this Section to
approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 

Section 9.03 Execution of Supplemental Indentures. 

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby
of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 6.01) shall be fully protected in relying upon, an Officers’ Certificate and an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but 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.

Section 9.07 Reference in Securities to Supplemental Indentures. 

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article 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. If the Partnership shall so determine, new Securities of any series so modified as to conform, in the opinion
of the Trustee and the Partnership, to any such supplemental indenture may be prepared and executed by the Partnership and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 

ARTICLE X 

COVENANTS 
 
Section 10.01 Payment of Principal, Premium and Interest. 
 The Partnership covenants and agrees for the benefit of each
series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in accordance with the terms of the Securities of that series and this Indenture. An installment of principal,
premium, if any, or interest on the Securities shall be considered paid on the date it is due if the Trustee or Paying Agent (other than the Partnership or an Affiliate of the Partnership) holds for the benefit of the Holders, on that date,
immediately available funds deposited and designated for and sufficient to pay the installment. 

Section 10.02 Maintenance of Office or Agency. 

The Partnership shall maintain in the Place of Payment for any series of Securities, an office or agency where Securities of that series may
be presented or surrendered for payment, where Securities of that series may be surrendered for registration of transfer or exchange and where notices and demands to or upon the Partnership in respect of the Securities of that series and this
Indenture may be served. The Partnership shall 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 such presentations, surrenders, notices and demands. 
 The Partnership may also from time to time designate one or
more other offices or agencies where the Securities of one or more series may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission
shall in any manner relieve the Partnership of its obligation to maintain an office or agency in 

  
 51 













 
each Place of Payment for Securities of any series for such purposes. The Partnership shall give prompt written notice to the Trustee of any such designation or rescission and of any change in
the location of any such other office or agency. 
 Except as otherwise specified with respect to a series of Securities as contemplated by
Section 3.01, the Partnership hereby initially designates as the Place of Payment for each series of Securities The City of New York, and initially appoints the Trustee Paying Agent at its corporate trust office located at [Trustee’s
Address], as the Partnership’s office or agency for each such purpose in such city. 

Section 10.03 Money for Securities Payments to Be Held in Trust. 

If the Partnership or any of its Subsidiaries shall at any time act as its own Paying Agent with respect to any series of Securities, it will,
on or before each due date of the principal of or any premium or interest on any of the Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and
interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 

Whenever the Partnership shall have one or more Paying Agents for any series of Securities, it will, on or prior to each due date of the
principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the
Partnership will promptly notify the Trustee in writing of its action or failure so to act. 
 The Partnership will cause each Paying Agent
for any series of Securities other than the Trustee to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply
with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Partnership (or any other obligor upon the Securities of that series) in the making of any payment in respect
of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the Securities of that series. 

The Partnership may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay,
or by Partnership Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Partnership or such Paying Agent, 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; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money. 

Any money deposited with the Trustee or any Paying Agent in trust for the payment of the principal of or any premium or interest on any
Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the state whose escheat laws control and the Trustee or any Paying Agent shall be discharged from such
trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only to the state whose escheat laws control for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money,
and all liability of the Partnership as trustee thereof, shall thereupon cease. 

  
 52 













 Section 10.04 Statement by Officers as to
Default. 
 The Partnership will deliver to the Trustee, within 150 days after the end of each fiscal year of the Partnership ending
after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signer thereof the Partnership is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture
(without regard to any period of grace or requirement of notice provided hereunder) and, if the Partnership shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 

Section 10.05 Existence. 

Subject to Article VIII, the Partnership will do or cause to be done all things necessary to preserve and keep in full force and effect
its existence, rights (charter and statutory) and material franchises; provided, however, that the Partnership shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Partnership. 
 Section 10.06 Limitations on Liens. 

The Partnership will not, nor will it permit any Restricted Subsidiary to, create, assume, incur or suffer to exist any Lien upon any
Principal Property, or upon any Capital Interests of any Restricted Subsidiary owning or leasing any Principal Property, whether owned or leased on the date of this Indenture or thereafter acquired, to secure any Debt of the Partnership or any other
Person (other than the Securities issued hereunder), without in any such case making effective provision whereby all of the Securities Outstanding hereunder shall be secured equally and ratably with, or prior to, such Debt so long as such Debt shall
be so secured. This restriction shall not apply to: 
 (1) Permitted Liens; 

(2) any Lien upon any property or assets created at the time of acquisition of such property or assets by the Partnership or any Restricted
Subsidiary or within one year after such time to secure all or a portion of the purchase price for such property or assets or Debt incurred to finance such purchase price, whether such Debt was incurred prior to, at the time of or within one year
after the date of such acquisition; 
 (3) any Lien upon any property or assets to secure all or part of the cost of construction,
development, repair or improvements thereon or to secure Debt incurred prior to, at the time of, or within one year after completion of such construction, development, repair or improvements or the commencement of full operations thereof (whichever
is later), to provide funds for any such purpose; 
 (4) any Lien upon any property or assets existing thereon at the time of the
acquisition thereof by the Partnership or any Restricted Subsidiary (whether or not the obligations secured thereby are assumed by the Partnership or any Restricted Subsidiary); provided, however, that such Lien only encumbers the property or assets
so acquired; 
 (5) any Lien upon any property or assets of a Person existing thereon at the time such Person becomes a Restricted
Subsidiary by acquisition, merger or otherwise; provided, however, that such Lien only encumbers the property or assets of such Person at the time such Person becomes a Restricted Subsidiary; 

  
 53 













 (6) any Lien upon any property or assets of the Partnership or any Restricted Subsidiary in
existence on the Issue Date or provided for pursuant to agreements existing on the Issue Date; 
 (7) Liens imposed by law or order as a
result of any proceeding before any court or regulatory body that is being contested in good faith, and Liens which secure a judgment or other court-ordered award or settlement in an aggregate amount not in excess of $1,000,000 as to which the
Partnership or the applicable Restricted Subsidiary, as the case may be, has not exhausted its appellate rights; 
 (8) any extension,
renewal, refinancing, refunding or replacement (or successive extensions, renewals, refinancing, refunding or replacements) of Liens, in whole or in part, referred to in Clauses (1) through (8), inclusive, of this Section; provided, however,
that any such extension, renewal, refinancing, refunding or replacement Lien shall be limited to the property or assets covered by the Lien extended, renewed, refinanced, refunded or replaced and that the obligations secured by any such extension,
renewal, refinancing, refunding or replacement Lien shall be in an amount not greater than the amount of the obligations secured by the Lien extended, renewed, refinanced, refunded or replaced and any expenses of the Partnership and its Restricted
Subsidiaries (including any premium) incurred in connection with such extension, renewal, refinancing, refunding or replacement; or 
 (9)
any Lien resulting from the deposit of moneys or evidence of indebtedness in trust for the purpose of defeasing Debt of the Partnership or any Restricted Subsidiary. 

Notwithstanding the foregoing provisions of this Section, the Partnership may, and may permit any Restricted Subsidiary to, create, assume,
incur or suffer to exist any Lien upon any Principal Property to secure Debt of the Partnership or any Person (other than the Securities) that is not excepted by Clauses (1) through (9), inclusive, of this Section without securing the
Securities issued hereunder, provided that the aggregate principal amount of all Debt then outstanding secured by such Lien and all similar Liens, together with all Attributable Indebtedness from Sale-Leaseback Transactions (excluding Sale-Leaseback
Transactions permitted by Clauses (1) 
through (4), inclusive, of), does not exceed 10% of Consolidated Net Tangible Assets. 
 Section 10.07
Restriction of Sale-Leaseback Transaction. 
 The Partnership will not, and will not permit any Subsidiary to, engage in a
Sale-Leaseback Transaction, unless: 
 (1) such Sale-Leaseback Transaction occurs within one year from the date of completion of the
acquisition of the Principal Property subject thereto or the date of the completion of construction, development or substantial repair or improvement, or commencement of full operations on such Principal Property, whichever is later; 

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

(3) the Attributable Indebtedness from that Sale-Leaseback Transaction is an amount equal to or less than the amount the Partnership or such
Subsidiary would be allowed to incur as Debt secured by a Lien on the Principal Property subject thereto without equally and ratably securing the Securities; or 

  
 54 













 (4) the Partnership or such Subsidiary, within a
one-year period after such Sale-Leaseback Transaction, applies or causes to be applied an amount not less than the net sale proceeds from such Sale-Leaseback Transaction
to (A) the prepayment, repayment, redemption, reduction or retirement of any Pari Passu Debt of the Partnership or any Subsidiary, or (B) the expenditure or expenditures for Principal Property used or to be used in the ordinary course of
business of the Partnership or its Subsidiaries. 
 Notwithstanding the foregoing provisions of this Section, the Partnership may, and may
permit any Subsidiary to, effect any Sale-Leaseback Transaction that is not excepted by Clauses (1) through (4), inclusive, of this Section, provided that the Attributable Indebtedness from such Sale-Leaseback Transaction, together with the
aggregate principal amount of then outstanding Debt (other than the Securities) secured by Liens upon Principal Properties not excepted by Clauses (1) through (9), inclusive, of Section 10.06, do not exceed 10% of the Consolidated Net
Tangible Assets. 
 Section 10.08 Waiver of Certain Covenants. 

The Partnership may omit in any particular instance to comply with any term, provision or condition set forth in Section 10.05, 10.06 or
10.07 with respect to the Securities of any series if before the time for such compliance the Holders of at least a majority in aggregate principal amount of the Outstanding Securities of all affected series (voting as one class) shall, by Act of
such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition 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 term, provision or condition shall remain in full force and effect. 

A waiver which changes or eliminates any term, provision or condition of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the rights of the Holders of Securities of such series with respect to such term, provision or condition, shall be deemed not to affect the rights under this Indenture of the
Holders of Securities of any other series. 
 ARTICLE XI 

REDEMPTION OF SECURITIES 
 
Section 11.01 Applicability of Article. 
 Securities of any series which are redeemable before their Stated Maturity shall
be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 3.01 for Securities of any series) in accordance with this Article. 

Section 11.02 Election to Redeem; Notice to Trustee. 

The election of the Partnership to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election
of the Partnership of less than all the Securities of any series, the Partnership shall, at least 60 days prior to the Redemption Date fixed by the Partnership (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in
writing of such Redemption Date, of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities (1) prior to the expiration of
any restriction on such redemption provided in the terms of such Securities or elsewhere in 

  
 55 













 
this Indenture, or (2) pursuant to an election of the Partnership which is subject to a condition specified in the terms of such Securities, the Partnership shall furnish the Trustee with an
Officers’ Certificate evidencing compliance with such restriction or condition. 
 Section 11.03
Selection by Trustee of Securities to be Redeemed. 
 If less than all the Securities of any series are to be redeemed (unless all
the Securities of such series and of a specified tenor are to be redeemed), the particular Securities to be redeemed shall be selected not more than 60 days prior to the Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem fair and appropriate and which complies with any securities exchange or other applicable requirements for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such series of a denomination larger than the minimum authorized denomination for Securities of that series. 

The Trustee shall promptly notify the Partnership in writing of the Securities selected for redemption and, in the case of any Securities
selected for partial redemption, the principal amount thereof to be redeemed. 
 For all purposes of this Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be
redeemed. 
 Section 11.04 Notice of Redemption. 

Notice of redemption shall be given by first-class mail (if international mail, by air mail), postage prepaid, mailed not less than 30 nor
more than 60 days prior to the Redemption Date, to each Holder of Securities to be redeemed, at his address appearing in the Security Register. 

All notices of redemption shall state: 

(1) the Redemption Date, 
 (2)
the Redemption Price, 
 (3) if less than all the Outstanding Securities of any series and of a specified tenor are to be redeemed, the
identification (and, in the case of partial redemption of any Securities, the principal amounts) of the particular Securities to be redeemed, 

(4) that on the Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable,
that interest thereon will cease to accrue on and after said date, the place or places where such Securities are to be surrendered for payment of the Redemption Price, 

(5) that the redemption is for a sinking fund, if such is the case; and 

(6) applicable CUSIP numbers. 

Notice of redemption of Securities to be redeemed at the election of the Partnership shall be given by the Partnership or, at the
Partnership’s request, by the Trustee in the name and at the expense of the Partnership and shall be irrevocable. 

  
 56 













 Section 11.05 Deposit of Redemption Price. 

On or prior to 10:30 a.m. New York City Time on any Redemption Date, 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 as provided in Section 10.03) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment
Date) accrued interest on, all the Securities which are to be redeemed on that date. 
 Section 11.06
Securities Payable on Redemption Date. 
 Notice of redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Partnership shall default in the payment of the Redemption Price and accrued interest) such Securities shall
cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Partnership at the Redemption Price, together with accrued interest to the Redemption Date; provided,
however, that, unless otherwise specified as contemplated by Section 3.01, installments of interest whose Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record Dates according to their terms and the provisions of Section 3.07. 

If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until
paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 

Section 11.07 Securities Redeemed in Part. 

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Partnership or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Partnership 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 Security without service charge, a new Security or Securities of the same series and of like tenor, 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 Security so surrendered. 

ARTICLE XII 

SINKING FUNDS 
 
Section 12.01 Applicability of Article. 
 The provisions of this Article shall be applicable to any sinking fund for the
retirement of Securities of a series except as otherwise specified as contemplated by Section 3.01 for Securities of such series. 

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series 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 Securities of any series is herein referred to as an “optional sinking fund payment.” If provided for by the terms of
Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.02. Each sinking fund payment shall be applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series. 

  
 57 













 Section 12.02 Satisfaction of Sinking Fund
Payments with Securities. 
 The Partnership (1) may deliver Outstanding Securities of a series (other than any previously called
for redemption), and (2) may apply as a credit Securities of a series which have been redeemed either at the election of the Partnership pursuant to the terms of such Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for
by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption
through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
 
Section 12.03 Redemption of Securities for Sinking Fund. 
 Not less than 45 days prior to each sinking fund payment date
for any series of Securities (unless a shorter period shall be satisfactory to the Trustee), the Partnership will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series
pursuant to the terms of that series, 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 Securities of that series pursuant to
Section 12.02 and stating the basis for such credit and that such Securities have not been previously so credited, and will also deliver to the Trustee any Securities to be so delivered. Not less than 30 days before each such sinking fund
payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.03 and cause notice of the redemption thereof to be given in the name of and at the expense of the
Partnership in the manner provided in Section 11.04. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 11.06 and 11.07. 

ARTICLE XIII 

DEFEASANCE 
 
Section 13.01 Applicability of Article. 
 The provisions of this Article shall be applicable to each series of Securities
except as otherwise specified as contemplated by Section 3.01 for Securities of such series. 

Section 13.02 Legal Defeasance. 

In addition to discharge of the Indenture pursuant to Section 4.01, the Partnership shall be deemed to have paid and discharged the
entire indebtedness on all the Securities of such a series on the 91st day after the date of the deposit referred to in Clause (1) below, and the provisions of this Indenture with respect to the Securities of such series shall no longer be in
effect (except as to (i) rights of registration of transfer and exchange of Securities of such series and the Partnership’s right of optional redemption, if any, (ii) substitution of mutilated, destroyed, lost or stolen Securities,
(iii) rights of Holders of Securities to receive payments of principal thereof and interest thereon, upon the original stated due dates therefor or on the specified redemption dates therefor (but not upon acceleration), and remaining rights of
the holders to receive mandatory sinking fund payments, if any, (iv) the rights, obligations, 

  
 58 













 
duties and immunities of the Trustee hereunder, and the Partnership’s obligations in connection therewith (including, but not limited to, Section 6.07), (v) the rights, if any, to
convert or exchange the Securities of such series, (vi) the rights of the Holders of Securities of such series as beneficiaries hereof with respect to the property so deposited with the Trustee payable to all or any of them, and (vii) the
obligations of the Partnership under Section 10.02), and the Trustee, at the expense of the Partnership, shall, upon a Partnership Request, execute proper instruments acknowledging the same, if the conditions set forth below are satisfied
(hereinafter, “defeasance”): 
 (1) The Partnership has irrevocably deposited or caused to be deposited with the Trustee as trust
funds in trust, for the purposes of making the following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series (A) cash in an amount, or (B) in the case of any
series of Securities the payments on which may only be made in legal coin or currency of the United States, U.S. Government Obligations, maturing as to principal and interest at such times and in such amounts as will insure the availability of cash,
or (C) a combination thereof, certified to be sufficient, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay (i) the principal and
interest and premium, if any, on all Securities of such series on each date that such principal, interest or premium, if any, is due and payable or on any Redemption Date established pursuant to Clause (3) below, and (ii) any mandatory
sinking fund payments on the dates on which such payments are due and payable in accordance with the terms of the Indenture and the Securities of such series; 

(2) The Partnership has delivered to the Trustee an Opinion of Counsel based on the fact that (A) the Partnership has received from, or
there has been published by, the Internal Revenue Service a ruling, or (B) since the date hereof, there has been a change in the applicable federal income tax law, in either case to the effect that, and such opinion shall confirm that, the
Holders of the 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 amount and in the same
manner and at the same times, as would have been the case if such deposit, defeasance and discharge had not occurred; 
 (3) If the
Securities are to be redeemed prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor satisfactory to the
Trustee shall have been made; 
 (4) No Event of Default or event which with notice or lapse of time or both would become an Event of
Default shall have occurred and be continuing on the date of such deposit; 
 (5) Such defeasance shall not cause the Trustee to have a
conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act); 

(6) Such defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which
the Partnership is a party or by which it is bound; 
 (7) Such defeasance shall not result in the trust arising from such deposit
constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered under such Act or exempt from registration thereunder; and 

  
 59 













 (8) The Partnership has delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, each stating that all conditions precedent provided for relating to the defeasance contemplated by this provision have been complied with. 

For this purpose, such defeasance means that the Partnership and any other obligor upon the Securities of such series shall be deemed to have
paid and discharged the entire debt represented by the Securities of such series, which shall thereafter be deemed to be “Outstanding” only for the purposes of Section 13.04 and the rights and obligations referred to in Clauses
(i) through (vii), inclusive, of the first paragraph of this Section, and to have satisfied all its other obligations under the Securities of such series and this Indenture insofar as the Securities of such series are concerned. 

Section 13.03 Covenant Defeasance. 

The Partnership and any other obligor, if any, shall be released on the date of the deposit referred to in Clause (1) below from its
obligations under Sections 7.04, 8.01, 10.05, 10.06 and 10.07 with respect to the Securities of any series on and after the date the conditions set forth below are satisfied (hereinafter, “covenant defeasance”), and the Securities of
such series shall thereafter be deemed to be not “Outstanding” for the purposes of any request, demand, authorization, direction, notice, waiver, consent or declaration or other action or Act of Holders (and the consequences of any
thereof) in connection with such covenants, but shall continue to be deemed Outstanding for all other purposes hereunder. For this purpose, such covenant defeasance means that, with respect to the Securities of such series, the Partnership may omit
to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such Section, whether directly or indirectly by reason of any reference elsewhere herein to such Section or by reason of any reference in
such Section to any other provision herein or in any other document and such omission to comply shall not constitute a Default or an Event of Default under Section 5.01, but, except as specified above, the remainder of this Indenture and the
Securities of such series shall be unaffected thereby. The following shall be the conditions to application of this Section 13.03: 

(1) The Partnership has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely to, the benefit of the Holders of the Securities of such series, (A) cash in an amount, or (B) in the case of any series of Securities the payments on which may
only be made in legal coin or currency of the United States, U.S. Government Obligations, maturing as to principal and interest at such times and in such amounts as will insure the availability of cash, or (C) a combination thereof, sufficient,
in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay (i) the principal and interest and premium, if any, on all Securities of such series
on each date that such principal, interest or premium, if any, is due and payable or on any Redemption Date established pursuant to Clause (2) below, and (ii) any mandatory sinking fund payments on the day on which such payments are due
and payable in accordance with the terms of the Indenture and the Securities of such series; 
 (2) If the Securities are to be redeemed
prior to Stated Maturity (other than from mandatory sinking fund payments or analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee shall have been made;

 (3) No Event of Default or event which with notice or lapse of time or both would become an Event of Default shall have occurred and be
continuing on the date of such deposit; 

  
 60 













 (4) The Partnership has delivered to the Trustee an Opinion of Counsel which shall confirm
that the Holders of the Securities of such series will not recognize income, gain or loss for federal income tax purposes as a result of such deposit and covenant defeasance and will be subject to federal income tax on the same amount and in the
same manner and at the same time as would have been the case if such deposit and covenant defeasance had not occurred; 
 (5) Such covenant
defeasance shall not cause the Trustee to have a conflicting interest within the meaning of the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act); 

(6) Such covenant defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to
which the Partnership is a party or by which it is bound; 
 (7) Such covenant defeasance shall not result in the trust arising from such
deposit constituting an investment company within the meaning of the Investment Company Act of 1940, as amended, unless such trust shall be registered under such Act or exempt from registration thereunder; and 

(8) The Partnership has delivered to the Trustee an Officers’ Certificate and Opinion of Counsel stating that all conditions precedent
provided for relating to the covenant defeasance contemplated by this provision have been complied with. 

Section 13.04 Application by Trustee of Funds Deposited for Payment of Securities. 

Subject to the provisions of the last paragraph of Section 10.03, all moneys or U.S. Government Obligations deposited with the Trustee
pursuant to Section 13.02 or 13.03 (and all funds earned on such moneys or U.S. Government Obligations) shall be held in trust and applied by it to the payment, either directly or through any Paying Agent (including the Partnership acting as
its own Paying Agent), to the Holders of the particular Securities of such series for the payment or redemption of which such moneys have been deposited with the Trustee, of all sums due and to become due thereon for principal and interest; but such
money need not be segregated from other funds except to the extent required by law. Subject to Sections 13.02 and 13.03, the Trustee shall promptly pay to the Partnership upon Partnership Order any moneys held by it at any time, which, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written certification delivered to the Trustee, are in excess of the amounts required to effect the defeasance with respect to the Outstanding Securities in
question. 
 Section 13.05 Repayment to Partnership. 

The Trustee and any Paying Agent promptly shall pay or return to the Partnership upon Partnership Request any money and U.S. Government
Obligations held by them at any time that are not required for the payment of the principal of and any interest on the Securities of any series for which money or U.S. Government Obligations have been deposited pursuant to Section 13.02 or
13.03, which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification delivered to the Trustee, are in excess of the amounts required to effect the defeasance with respect to the
Outstanding Securities in question. 
 The provisions of the last paragraph of Section 10.03 shall apply to any money held by the
Trustee or any Paying Agent under this Article that remains unclaimed for two years after the Maturity of any series of Securities for which money or U.S. Government Obligations have been deposited pursuant to Section 13.02 or 13.03. 

  
 61 













 Section 13.06 Reinstatement. 

If the Trustee or the Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article by reason of
any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the obligations of the Partnership under this Indenture and the Securities of the
applicable series shall be revived and reinstated as though no deposit had occurred pursuant to this Indenture until such time as the Trustee or the Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with
this Article; provided, however, that if the Partnership has made any payment of principal of or interest on any Securities of such series because of the reinstatement of its obligations, the Partnership shall be subrogated to the rights of the
Holders of such Securities to receive such payment from the money or U.S. Government Obligations held by the Trustee or the Paying Agent. 
 
ARTICLE XIV 
 SUBORDINATION OF SECURITIES 

Section 14.01 Agreement to Subordinate. 

Each Holder by accepting a Security agrees that the Indebtedness evidenced by such Security is subordinated in right of payment, to the extent
and in the manner provided in this Article XIV, to the prior payment of all Senior Indebtedness and that the subordination is for the benefit of and enforceable by the holders of Senior Indebtedness. All provisions of this Article XIV shall be
subject to Section 14.12. 
 Section 14.02 Liquidation, Dissolution, Bankruptcy. 

Upon any payment or distribution of the assets of the Partnership to creditors upon a total or partial liquidation or a total or partial
dissolution of the Partnership or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to the Partnership or its property: 

(1) holders of Senior Indebtedness of the Partnership shall be entitled to receive payment in full in cash of such Senior Indebtedness
(including interest (if any), accruing on or after the commencement of a proceeding in bankruptcy, whether or not allowed as a claim against the Partnership in such bankruptcy proceeding) before Holders of Securities from the Partnership shall be
entitled to receive any payment of principal of, or premium, if any, or interest on, the Securities; and 
 (2) until the Senior
Indebtedness is paid in full, any distribution to which Holders of Securities would be entitled but for this Article XIV shall be made to holders of Senior Indebtedness of the Partnership as their interests may appear, except that such Holders may
receive shares of stock and any debt securities that are subordinated to Senior Indebtedness of the Partnership to at least the same extent as the Securities of the Partnership. 

Section 14.03 Default on Senior Indebtedness. 

The Partnership may not pay the principal of, or premium, if any, or interest on, the Securities or make any deposit pursuant to Article IV
and may not repurchase, redeem or otherwise retire (except, in the case of Securities that provide for a mandatory sinking fund pursuant to Section 12.01, by the delivery of Securities by the Partnership to the Trustee pursuant to
Section 12.03) any Securities (collectively, “pay the Securities”) if (a) any principal, premium or interest in respect of Senior Indebtedness is not paid within any applicable grace period (including at maturity) or (b) any
other default on Senior Indebtedness occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in 

  
 62 













 
either case, the default has been cured or waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in full in cash; provided, however, that the Partnership
may pay the Securities without regard to the foregoing if the Partnership and the Trustee receive written notice approving such payment from the Representative of each issue of Designated Senior Indebtedness. During the continuance of any default
(other than a default described in clause (a) or (b) of the preceding sentence) with respect to any Designated Senior Indebtedness pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice
as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Partnership may not pay the Securities for a period (a “Payment Blockage Period”) commencing upon the receipt by the Partnership and the
Trustee of written notice of such default from the Representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period (a “Blockage Notice”) and ending 179 days thereafter (or earlier if such
Payment Blockage Period is terminated by written notice to the Trustee and the Partnership from the Person or Persons who gave such Blockage Notice, by repayment in full in cash of such Designated Senior Indebtedness or because the default giving
rise to such Blockage Notice is no longer continuing). Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in the first sentence of this Section 14.03), unless the holders of
such Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, the Partnership may resume payments on the Securities after such Payment Blockage Period. Not more
than one Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to any number of issues of Designated Senior Indebtedness during such period, unless
otherwise specified pursuant to Section 3.01 for the Securities of a series; provided, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate
during any 360 consecutive day period. For purposes of this Section 14.03, no default or event of default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior
Indebtedness initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360
consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 

Section 14.04 Acceleration of Payment of Securities. 

If payment of the Securities is accelerated because of an Event of Default, the Partnership shall promptly notify the holders of the
Designated Senior Indebtedness (or their Representatives) of the acceleration. 
 Section 14.05
When Distribution Must Be Paid Over. 
 If a distribution is made to Holders of Securities that because of this Article XIV should
not have been made to them, the Holders who receive such distribution shall hold it in trust for holders of Senior Indebtedness and pay it over to them as their interests may appear. 

Section 14.06 Subrogation. 

After all Senior Indebtedness is paid in full and until the Securities are paid in full, Holders thereof shall be subrogated to the rights of
holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness. A distribution made under this Article XIV to holders of Senior Indebtedness which otherwise would have been made to Holders of Securities is not, as between
the Partnership and such Holders, a payment by the Partnership on Senior Indebtedness. 

  
 63 













 Section 14.07 Relative Rights. 

This Article XIV defines the relative rights of Holders of Securities and holders of Senior Indebtedness. Nothing in this Indenture shall:

 (1) impair, as between the Partnership and Holders of the Securities, the obligation of the Partnership which is absolute and
unconditional, to pay principal of, and premium, if any, and interest on, the Securities in accordance with their terms; or 
 (2) prevent
the Trustee or any Holder of the Securities from exercising its available remedies upon a Default, subject to the rights of holders of Senior Indebtedness to receive distributions otherwise payable to Holders of Securities. 

Section 14.08 Subordination May Not Be Impaired by Partnership. 

No right of any holder of Senior Indebtedness to enforce the subordination of the Indebtedness evidenced by the Securities shall be impaired
by any act or failure to act by the Partnership or by its failure to comply with this Indenture. 

Section 14.09 Rights of Trustee and Paying Agent. 

Notwithstanding Section 14.03, the Trustee or any paying agent may continue to make payments on Securities and shall not be charged with
knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, the Trustee receives notice satisfactory to the Trustee that payments may not be made
under this Aricle XIV. The Partnership, the Security Registrar, any paying agent, a Representative or a holder of Senior Indebtedness may give the notice; provided, however, that, if an issue of Senior Indebtedness has a Representative, only the
Representative may give the notice on behalf of the Holders of the Senior Indebtedness of that issue. 
 The Trustee in its individual or
any other capacity may hold Senior Indebtedness with the same rights it would have if it were not Trustee. The Security Registrar and any paying agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in
this Aricle XIV with respect to any Senior Indebtedness which may at any time be held by it, to the same extent as any other holder of Senior Indebtedness; and nothing in Article VI shall deprive the Trustee of any of its rights as such holder.
Nothing in this Aricle XIV shall apply to claims of, or payments to, the Trustee under or pursuant to Section 
6.07. 
 Section 14.10 Distribution or Notice to Representative. 

Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given
to their Representative (if any). 
 Section 14.11 Aricle XIV Not to Prevent Defaults or Limit
Right to Accelerate. 
 The failure to make a payment pursuant to the Securities by reason of any provision in this Article XIV shall
not be construed as preventing the occurrence of an Event of Default. Nothing in this Article XIV shall have any effect on the right of the Holders or the Trustee to accelerate the maturity of the Securities. 

  
 64 













 Section 14.12 Trust Moneys Not Subordinated.

 Notwithstanding anything contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in
trust under Article IV by the Trustee for the payment of principal of, and premium, if any, and interest on, the Securities shall not be subordinated to the prior payment of any Senior Indebtedness or subject to the restrictions set forth in this
Aricle XIV, and none of the Holders thereof shall be obligated to pay over any such amount to the Partnership or any holder of Senior Indebtedness of the Partnership or any other creditor of the Partnership. 

Section 14.13 Trustee Entitled to Rely. 

Upon any payment or distribution pursuant to this Aricle XIV, the Trustee and the Holders shall be entitled to rely upon any order or decree
of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 14.02 are pending, upon a certificate of the liquidating trustee or agent or other Person making such payment or distribution to the Trustee or
to such Holders or upon the Representatives for the holders of Senior Indebtedness for the purpose of ascertaining the Persons entitled to participate in such payment or distribution, the holders of the Senior Indebtedness and other Indebtedness of
the Partnership, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Aricle XIV. In the event that the Trustee determines, in good faith, that evidence is required
with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this Aricle XIV, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the
Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Aricle XIV, and, if
such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Sections 6.01 and 6.03 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Aricle XIV. 
 Section 14.14 Trustee to
Effectuate Subordination. 
 Each Holder by accepting a Security authorizes and directs the Trustee on his behalf to take such action as
may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders of Securities and the holders of Senior Indebtedness as provided in this Aricle XIV and appoints the Trustee as attorney-in-fact for any and all such purposes. 

Section 14.15 Trustee Not Fiduciary for Holders of Senior Indebtedness. 

The Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if
it shall mistakenly pay over or distribute to Holders of Securities or the Partnership or any other Person, money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Aricle XIV or otherwise. 

Section 14.16 Reliance by Holders of Senior Indebtedness on Subordination Provisions.
