other obligor. In determining whether the Holders of the requisite principal amount of Outstanding Debt Securities have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of an Original

principal of such security is due and payable, including pursuant to any mandatory redemption provision (but excluding any provision providing for the repurchase of such security at the option of the holder thereof upon the happening of any
contingency beyond the control of the issuer unless such contingency has occurred). 
 “Subsidiary” of any Person means: 

 

	 	(1)	any corporation, association or other business entity of which more than 50% of the total voting power of equity interests entitled, without regard to the occurrence of any contingency, to vote in the election of

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

Only such Debt Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed
manually by the Trustee, shall be entitled to the benefits of this Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee upon any Debt Security executed on behalf of each of the Issuers by at least one of its Officers
shall be conclusive evidence that the Debt Security so authenticated has been duly authenticated and delivered hereunder. 
 In case any
Officer of either Issuer who shall have signed any of the Debt Securities shall cease to be such Officer before the Debt Securities so signed shall have been authenticated and delivered by the Trustee, or disposed of by the Issuers, such Debt
Securities nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Debt Securities had not ceased to be such Officer; and any Debt Security may be signed on behalf of either Issuer by such Persons as, at
the actual date of the execution of such Debt Security, shall be the proper Officers of such Issuer, although at the date of such Debt Security or of the execution of this Indenture any such Person was not such Officer. 

  
 10 








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

(b) an executed supplemental Indenture, if any; 

(c) an Officers’ Certificate; and 

(d) an Opinion of Counsel prepared in accordance with Section 13.05 which shall also state: 

(i) that the form of such Debt Securities has been established by or pursuant to a resolution of the Board of Directors of each
Issuer or by a supplemental Indenture as permitted by Section 2.01 in conformity with the provisions of this Indenture; 

(ii) that the terms of such Debt Securities have been established by or pursuant to a resolution of the Board of Directors or
by a supplemental Indenture as permitted by Section 2.03 in conformity with the provisions of this Indenture; 
 (iii)
that such Debt Securities, when authenticated and delivered by the Trustee and issued by the Issuers in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the
Issuers, enforceable in accordance with their terms except as the enforceability thereof may be limited by bankruptcy, insolvency or similar laws affecting the enforcement of creditors’ rights generally and rights of acceleration and the
availability of equitable remedies may be limited by equitable principles of general applicability; 
 (iv) that the Issuers
have the power to issue such Debt Securities and has duly taken all necessary action with respect to such issuance; 
 (v)
that the issuance of such Debt Securities will not contravene the organizational documents of the Issuers or result in any material violation of any of the terms or provisions of any law or regulation or of any material indenture, mortgage or other
agreement known to such counsel by which the Issuers are bound; 
 (vi) that authentication and delivery of such Debt
Securities and the execution and delivery of any supplemental Indenture will not violate the terms of this Indenture; and 

(vii) such other matters as the Trustee may reasonably request. 

  
 11 








 Such Opinion of Counsel need express no opinion as to whether a court in the United States would
render a money judgment in a currency other than that of the United States. 
 The Trustee shall have the right to decline to authenticate
and deliver any Debt Securities under this Section 2.05 if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee
or a trust committee of directors, trustees or Officers (or any combination thereof) shall determine that such action would expose the Trustee to personal liability to existing Holders. 

The Trustee may appoint an authenticating agent reasonably acceptable to the Issuers to authenticate Debt Securities of any series. Unless
limited by the terms of such appointment, an authenticating agent may authenticate Debt Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An
authenticating agent has the same rights as any Registrar, paying agent or agent for service of notices and demands. 
 Unless otherwise
provided in the form of Debt Security for any series, each Debt Security shall be dated the date of its authentication. 
 Section 2.06
Denomination of Debt Securities. Unless otherwise provided in the form of Debt Security for any series, the Debt Securities of each series shall be issuable only as fully registered Debt Securities in such Dollar denominations as shall be
specified or contemplated by Section 2.03. In the absence of any such specification with respect to the Debt Securities of any series, the Debt Securities of such series shall be issuable in denominations of $1,000 and any integral multiple
thereof. 
 Section 2.07 Registration of Transfer and Exchange. 

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

Unless and until otherwise determined by the Issuers by resolutions of each Issuer’s Board of Directors, the Debt Security Register shall
be kept at the principal corporate trust office of the Trustee and, for this purpose, the Trustee shall be designated “Registrar.” 

Debt Securities of any series (other than a Global Security, except as set forth below) may be exchanged for a like aggregate principal amount
of Debt Securities of the same series of other authorized denominations. Subject to Section 2.15, Debt Securities to be exchanged shall 

  
 12 








 
be surrendered at the office or agency to be maintained by the Issuers as provided in Section 4.02, and the Issuers shall execute and the Trustee shall authenticate and deliver in exchange
therefor the Debt Security or Debt Securities which the Holder making the exchange shall be entitled to receive. 
 (b) All Debt Securities
presented or surrendered for registration of transfer, exchange or payment shall (if so required by the Issuers, the Trustee or the Registrar) be duly endorsed or be accompanied by a written instrument or instruments of transfer, in form
satisfactory to the Issuers, the Trustee and the Registrar, duly executed by the Holder or his attorney duly authorized in writing. 
 All
Debt Securities issued in exchange for or upon transfer of Debt Securities shall be the valid obligations of the Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture as the Debt Securities surrendered for such
exchange or transfer. 
 No service charge shall be made for any exchange or registration of transfer of Debt Securities (except as provided
by Section 2.09), but the Issuers may require payment of a sum sufficient to cover any tax, fee, assessment or other governmental charge that may be imposed in relation thereto, other than those expressly provided in this Indenture to be made
at the Issuers’ own expense or without expense or without charge to the Holders. 
 The Issuers shall not be required (i) to
issue, register the transfer of or exchange any Debt Securities for a period of 15 days next preceding any mailing of notice of redemption of Debt Securities of such series or (ii) to register the transfer of or exchange any Debt Securities
selected, called or being called for redemption, except for the unredeemed portion of any such Debt Securities. 
 Prior to the due
presentation for registration of transfer of any Debt Security, the Issuers, the Subsidiary Guarantors, the Trustee, any paying agent or any Registrar may deem and treat the Person in whose name a Debt Security is registered as the absolute owner of
such Debt Security for the purpose of receiving payment of or on account of the principal of, and premium, if any, and (subject to Section 2.12) interest on, such Debt Security and for all other purposes whatsoever, whether or not such Debt
Security is overdue, and none of the Issuers, the Subsidiary Guarantors, the Trustee, any paying agent or any Registrar shall be affected by notice to the contrary. 

None of the Issuers, the Subsidiary Guarantors, the Trustee, any agent of the Trustee, any paying agent or any Registrar will have any
responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership
interests. 
 Section 2.08 Temporary Debt Securities. Pending the preparation of definitive Debt Securities of any series, the
Issuers may execute and the Trustee shall authenticate and deliver temporary Debt Securities (printed, lithographed, photocopied, typewritten or otherwise produced) of any authorized denomination, and substantially in the form of the definitive Debt
Securities in lieu of which they are issued, in registered form with such omissions, insertions and 

  
 13 








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

Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Debt Securities
represented thereby pursuant to Section 2.07 or this Section 2.08, the temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such
temporary Global Security shall be reduced for all purposes by the amount to be exchanged and endorsed. 
 Section 2.09 Mutilated,
Destroyed, Lost or Stolen Debt Securities. If (a) any mutilated Debt Security is surrendered to the Trustee at its corporate trust office or (b) the Issuers and the Trustee receive evidence to their satisfaction of the destruction,
loss or theft of any Debt Security, and there is delivered to the Issuers and the Trustee such security or indemnity as may be required by them to save each of them and any paying agent harmless, and neither the Issuers nor the Trustee receives
notice that such Debt Security has been acquired by a protected purchaser, then the Issuers shall execute and, upon an Issuer Order, the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or
stolen Debt Security, a new Debt Security of the same series of like tenor, form, terms and principal amount, bearing a number not contemporaneously Outstanding. Upon the issuance of any substituted Debt Security, the Issuers or the Trustee may
require the payment of a sum sufficient to cover any tax, fee, assessment or other governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security which has matured or is about to
mature or which has been called for redemption shall become mutilated or be destroyed, lost or stolen, the Issuers may, instead of issuing a substituted Debt Security, pay or authorize the payment of the same (without surrender thereof except in the
case of a mutilated Debt Security) if the applicant for such payment shall furnish the Issuers and the Trustee with such security or indemnity as either may require to save it harmless from all risk, however remote, and, in case of destruction, loss
or theft, evidence to the satisfaction of the Issuers and the Trustee of the destruction, loss or theft of such Debt Security and of the ownership thereof. 

  
 14 








 Every substituted Debt Security of any series issued pursuant to the provisions of this
Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost or stolen shall constitute an original additional contractual obligation of the Issuers, whether or not the destroyed, lost or stolen Debt Security shall be found at
any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of that series duly issued hereunder. All Debt Securities shall be held and owned upon the express condition
that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities, and shall preclude any and all other rights or remedies, notwithstanding any law or statute existing or
hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or other securities without their surrender. 

Section 2.10 Cancellation of Surrendered Debt Securities. All Debt Securities surrendered for payment, redemption, registration of
transfer or exchange shall, if surrendered to an Issuer or any paying agent or a Registrar, be delivered to the Trustee for cancellation by it, or if surrendered to the Trustee, shall be canceled by it, and no Debt Securities shall be issued in lieu
thereof except as expressly permitted by any of the provisions of this Indenture. All canceled Debt Securities held by the Trustee shall be destroyed (subject to the record retention requirements of the Exchange Act) and certification of their
destruction delivered to the Issuers, unless otherwise directed. On request of the Issuers, the Trustee shall deliver to the Issuers canceled Debt Securities held by the Trustee. If either of the Issuers shall acquire any of the Debt Securities,
however, such acquisition shall not operate as a redemption or satisfaction of the Debt represented thereby unless and until the same are delivered or surrendered to the Trustee for cancellation. The Issuers may not issue new Debt Securities to
replace Debt Securities it has redeemed, paid or delivered to the Trustee for cancellation. 
 Section 2.11 Provisions of the
Indenture and Debt Securities for the Sole Benefit of the Parties and the Holders. Nothing in this Indenture or in the Debt Securities, expressed or implied, shall give or be construed to give to any Person, other than the parties hereto, the
Holders or any Registrar or paying agent, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision herein contained; all its covenants, conditions and provisions being for the
sole benefit of the parties hereto, the Holders and any Registrar and paying agents. 
 Section 2.12 Payment of Interest; Interest
Rights Preserved. 
 (a) Interest on any Debt Security that is payable and is punctually paid or duly provided for on any interest
payment date shall be paid to the Person in whose name such Debt Security is registered at the close of business on the regular record date for such interest notwithstanding the cancellation of such Debt Security upon any transfer or exchange
subsequent to the regular record date. Payment of interest on Debt Securities shall be made at the corporate trust office of the Trustee (except as otherwise specified pursuant to Section 2.03), or at the option of the Issuers, by check mailed
to the address of the Person entitled thereto as such address shall appear in the Debt Security Register or, if provided pursuant to Section 2.03 and in accordance with arrangements satisfactory to the Trustee, at the option of the Holder by
wire transfer to an account designated by the Holder. 

  
 15 








 (b) Subject to the foregoing provisions of this Section 2.12 and Section 2.17, each
Debt Security of a particular series delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debt Security of the same series shall carry the rights to interest accrued and unpaid, and to accrue,
which were carried by such other Debt Security. 
 Section 2.13 Securities Denominated in Dollars. Except as otherwise specified
pursuant to Section 2.03 for Debt Securities of any series, payment of the principal of, and premium, if any, and interest on, Debt Securities of such series will be made in Dollars. 

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

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

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

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

  
 16 








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

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

(c) If at any time the Depositary for a Global Security or Securities notifies the Issuers that it is unwilling or unable to continue as
Depositary for such Global Security or Securities or if at any time the Depositary for the Debt Securities for such series shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or regulation, the
Issuers shall appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security or Securities is not appointed by the Issuers within 90 days after the Issuers receive such notice or
become aware of such ineligibility, the Issuers shall execute, and the Trustee or its agent, upon receipt of an Issuer Order for the authentication and delivery of such individual Debt Securities of such series in exchange for such Global Security
or Securities, will authenticate and deliver, individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security or Securities in exchange for
such Global Security or Securities. 
 If an Event of Default occurs and the Depositary for a Global Security or Securities notifies the
Trustee of its decision to require that the Debt Securities of any series or portion thereof issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities, the Issuers shall
appoint a successor Depositary with respect to such Global Security or Securities. In such event the Issuers will execute, and the Trustee, upon receipt of an Issuer Order for the authentication and delivery of individual Debt Securities of such
series in exchange in whole or in part for such Global Security or Securities, will authenticate and deliver individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal
amount of such series or portion thereof in exchange for such Global Security or Securities. 
 If specified by the Issuers pursuant to
Sections 2.01 and 2.03 with respect to Debt Securities issued or issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual Debt Securities of
such series of like tenor and terms in definitive form on such terms as are acceptable to the Issuers, the Trustee and such Depositary. Thereupon the Issuers shall execute, and the Trustee or its agent upon receipt of an Issuer Order for the
authentication and delivery of 

  
 17 








 
definitive Debt Securities of such series shall authenticate and deliver, without service charge, to each Person specified by such Depositary a new Debt Security or Securities of the same series
of like tenor and terms and of any authorized denomination as requested by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security; and to such Depositary a new Global
Security of like tenor and terms and in an authorized denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt Securities delivered to Holders thereof.

 In any exchange provided for in any of the preceding three paragraphs, the Issuers will execute and the Trustee or its agent will
authenticate and deliver individual Debt Securities. Upon the exchange of the entire principal amount of a Global Security for individual Debt Securities, such Global Security shall be canceled by the Trustee or its agent. Except as provided in the
preceding paragraph, Debt Securities issued in exchange for a Global Security pursuant to this Section 2.15 shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall instruct the Trustee or the Registrar. The Trustee or the Registrar shall deliver such Debt Securities to the Persons in whose names such Debt Securities are so registered.

 Payments in respect of the principal of and interest on any Debt Securities registered in the name of the Depositary or its nominee will
be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Issuers, any Subsidiary Guarantors and the Trustee may treat the Person in whose name the Debt Securities, including the Global
Security, are registered as the owner thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Issuers, any Subsidiary Guarantors, the Trustee, any Registrar, the paying agent or any agent of the
Issuers, any Subsidiary Guarantors or the Trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its
nominee or any of the Depositary’s direct or indirect participants, or for maintaining, supervising or reviewing any records of the Depositary, its nominee or any of its direct or indirect participants relating to the beneficial ownership
interests of the Global Security, the payments to the beneficial owners of the Global Security of amounts paid to the Depositary or its nominee, or any other matter relating to the actions and practices of the Depositary, its nominee or any of its
direct or indirect participants. None of the Issuers, any Subsidiary Guarantors, the Trustee or any such agent will be liable for any delay by the Depositary, its nominee, or any of its direct or indirect participants in identifying the beneficial
owners of the Debt Securities, and the Issuers, any Subsidiary Guarantors and the Trustee may conclusively rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes (including with respect to the
registration and delivery, and the respective principal amounts, of the Debt Securities to be issued). 
 Section 2.16 Medium Term
Securities. Notwithstanding any contrary provision herein, if all Debt Securities of a series are not to be originally issued at one time, it shall not be necessary for each of the Issuers to deliver to the Trustee an Officers’ Certificate,
resolutions of each such Issuer’s Board of Directors, supplemental Indenture, Opinion of Counsel or written order or any other document otherwise required pursuant to Section 2.01, 2.03, 2.05 or 13.05 at


  
 18 








 
or prior to the time of authentication of each Debt Security of such series if such documents are delivered to the Trustee or its agent at or prior to the authentication upon original issuance of
the first such Debt Security of such series to be issued; provided, that any subsequent request by the Issuers to the Trustee to authenticate Debt Securities of such series upon original issuance shall constitute a representation and warranty by the
Issuers that, as of the date of such request, the statements made in the Officers’ Certificate delivered pursuant to Section 2.05 or 13.05 shall be true and correct as if made on such date and that the Opinion of Counsel delivered at or
prior to such time of authentication of an original issuance of Debt Securities shall specifically state that it shall relate to all subsequent issuances of Debt Securities of such series that are identical to the Debt Securities issued in the first
issuance of Debt Securities of such series. 
 An Issuer Order delivered by the Issuers to the Trustee in the circumstances set forth in the
preceding paragraph, may provide that Debt Securities which are the subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time upon the telephonic or written order of Persons designated in
such written order (any such telephonic instructions to be promptly confirmed in writing by such Person) and that such Persons are authorized to determine, consistent with the Officers’ Certificate, supplemental Indenture or resolution of the
Board of Directors relating to such written order, such terms and conditions of such Debt Securities as are specified in such Officers’ Certificate, supplemental Indenture or such resolution. 

Section 2.17 Defaulted Interest. Any interest on any Debt Security of a particular series which is payable, but is not
punctually paid or duly provided for, on the dates and in the manner provided in the Debt Securities of such series and in this Indenture (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the
relevant record date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Issuers, at their election in each case, as provided in clause (i) or (ii) below: 

(i) The Issuers may elect to make payment of any Defaulted Interest to the Persons in whose names the Debt Securities of such
series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest
proposed to be paid on each such Debt Security of such series and the date of the proposed payment, and at the same time the Issuers 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 Issuers of such special record date and, in the name and at the expense of the Issuers, shall cause notice of the
proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage pre-paid, to each Holder thereof at its address as it appears in the Debt Security Register,
not less than 10 days prior to such special record date. Notice of the proposed payment of such 

  
 19 








 
Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Debt Securities of such series are
registered at the close of business on such special record date. 
 (ii) The Issuers may make payment of any Defaulted
Interest on the Debt Securities of such series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debt Securities of such series may be listed, and upon such notice as may be required by such
exchange, if, after notice given by the Issuers to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 

Section 2.18 CUSIP Numbers. The Issuers in issuing the Debt Securities may use “CUSIP” numbers (if then generally in
use), and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the accuracy of such numbers either as printed on
the Debt Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Debt Securities, and any such redemption shall not be affected by any defect in or omission of
such numbers. The Issuers will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 ARTICLE III

 REDEMPTION OF DEBT SECURITIES 

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

Section 3.02 Notice of Redemption; Selection of Debt Securities. In case the Issuers shall desire to exercise the right to redeem
all or, as the case may be, any part of the Debt Securities of any series in accordance with their terms, by resolution of the Board of Directors of each Issuer or a supplemental Indenture, the Issuers shall fix a date for redemption and shall give
notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities of such series so to be redeemed as a whole or in part, in the manner provided in Section 13.03. The notice
if given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Debt Security of
a series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Debt Security of such series. 

Each such notice of redemption shall specify (i) the date fixed for redemption, (ii) the redemption price at which Debt Securities
of such series are to be redeemed (or the method of calculating such redemption price), (iii) the Place or Places of Payment that payment will be made upon presentation and surrender of such Debt Securities, (iv) that any interest accrued to
the date fixed for redemption will be paid as specified in said notice, (v) that the redemption is for a sinking fund payment (if applicable), (vi) that, unless otherwise specified in such notice, if the Issuers default in making such
redemption payment the paying agent is prohibited from making such payment pursuant to the terms of this Indenture, (vii) that on and after said date any 

  
 20 








 
interest thereon or on the portions thereof to be redeemed will cease to accrue, (viii) that in the case of Original Issue Discount Securities original issue discount accrued after the date
fixed for redemption will cease to accrue, (ix) the terms of the Debt Securities of that series pursuant to which the Debt Securities of that series are being redeemed and (x) that no representation is made as to the correctness or
accuracy of the CUSIP number, if any, listed in such notice or printed on the Debt Securities of that series. If less than all the Debt Securities of a series are to be redeemed the notice of redemption shall specify the certificate numbers of any
Debt Securities of that series to be redeemed that are not in global form. In case any Debt Security of a series is to be redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and
shall state that on and after the date fixed for redemption, upon surrender of such Debt Security, a new Debt Security or Debt Securities of that series in principal amount equal to the unredeemed portion thereof, will be issued. 

At least five days before the giving of any notice of redemption, unless the Trustee consents to a shorter period, the Issuers shall give
written notice to the Trustee of the Redemption Date, the aggregate principal amount of Debt Securities to be redeemed and the series and terms of the Debt Securities pursuant to which such redemption will occur. Such notice shall be accompanied by
an Officers’ Certificate and an Opinion of Counsel from the Issuers to the effect that such redemption will comply with the conditions herein, and such notice may be revoked at any time prior to the giving of a notice of redemption to the
Holders pursuant to this Section 3.02. If fewer than all the Debt Securities of a series are to be redeemed, the record date relating to such redemption shall be selected by the Issuers and given in writing to the Trustee, which record date
shall be not less than three days after the date of notice to the Trustee. 
 By 11:00 a.m., New York City time, on the Redemption Date for
any Debt Securities, the Issuers shall deposit with the Trustee or with a paying agent (or, if an Issuer is acting as its own paying agent, segregate and hold in trust) an amount of money in Dollars (except as provided pursuant to Section 2.03)
sufficient to pay the redemption price of such Debt Securities or any portions thereof that are to be redeemed on that date, together with any interest accrued to the Redemption Date. 

If less than all the Debt Securities of like tenor and terms of a series are to be redeemed (other than pursuant to mandatory sinking fund
redemptions), the Trustee shall select, on a pro rata basis, by lot or by such other method as in its sole discretion it shall deem appropriate and fair, the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed.
In any case where more than one Debt Security of such series is registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Debt Security of such series. The
Trustee shall promptly notify the Issuers in writing of the Debt Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed. If any Debt Security called for
redemption shall not be so paid upon surrender thereof on such Redemption Date, the principal, premium, if any, and interest shall bear interest until paid from the Redemption Date at the rate borne by the Debt Securities of that series. If less
than all the Debt Securities of unlike tenor and terms of a series are to be redeemed, the particular Debt Securities to be redeemed shall be selected by the Issuers. Provisions of this Indenture that apply to Debt Securities called for redemption
also apply to portions of Debt Securities called for redemption. 

  
 21 








 Section 3.03 Payment of Debt Securities Called for Redemption. If notice of
redemption has been given as provided in Section 3.02, the Debt Securities or portions of Debt Securities of the series with respect to which such notice has been given shall become due and payable on the date and at the Place or Places of
Payment stated in such notice at the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Issuers shall default in the payment of such Debt Securities at the
applicable redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt Securities of any series so called for redemption shall cease to accrue, and any original issue discount in the
case of Original Issue Discount Securities shall cease to accrue. On presentation and surrender of such Debt Securities at the Place or Places of Payment in said notice specified, the said Debt Securities or the specified portions thereof shall be
paid and redeemed by the Issuers at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption. 

Any Debt Security that is to be redeemed only in part shall be surrendered at the Place of Payment with, if the Issuers, the Registrar or the
Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers, the Registrar and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing, and the Issuers shall
execute, and the Trustee shall authenticate and deliver to the Holder of such Debt Security without service charge, a new Debt Security or Debt Securities of the same series, of like tenor and form, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Debt Security so surrendered; except that if a Global Security is so surrendered, the Issuers shall execute, and the Trustee shall
authenticate and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the
case of a Debt Security providing appropriate space for such notation, at the option of the Holder thereof, the Trustee, in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the
payment of the redeemed portion thereof. 
 Section 3.04 Mandatory and Optional Sinking Funds. The minimum amount of any sinking
fund payment provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such
minimum amount provided for by the terms of Debt Securities of any series, resolution of the Board of Directors or a supplemental Indenture is herein referred to as an “optional sinking fund payment.” 

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

  
 22 








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

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

  
 23 








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

PARTICULAR COVENANTS OF THE ISSUERS 

Section 4.01 Payment of Principal of, and Premium, If Any, and Interest on, Debt Securities. The Issuers, for the benefit of each
series of Debt Securities, will duly and punctually pay or cause to be paid the principal of, and premium, if any, and interest on, each of the Debt Securities at the place, at the respective times and in the manner provided herein or in the Debt
Securities. Each installment of interest on any Debt Securities not in global form may at the Issuers’ option be paid by mailing checks for such interest payable to the Person entitled thereto pursuant to Section 2.07(a) to the address of such
Person as it appears on the Debt Security Register. 
 Principal of and premium and interest on Debt Securities of any series shall be
considered paid on the date due if, by 11:00 a.m., New York City time, on such date the Trustee or any paying agent holds in accordance with this Indenture money sufficient to pay all principal, premium and interest then due. 

The Issuers shall pay interest on overdue principal or premium, if any, at the rate specified therefor in the Debt Securities, and they shall
pay interest on overdue installments of interest at the same rate to the extent lawful. 
 Section 4.02 Maintenance of Offices or
Agencies for Registration of Transfer, Exchange and Payment of Debt Securities. The Issuers will maintain in each Place of Payment for any series of Debt Securities an office or agency where Debt Securities of such series may be presented or
surrendered for payment, and they shall also maintain (in or outside such Place of Payment) an office or agency where Debt Securities of such series may be surrendered for transfer or exchange and where notices and demands to or upon the Issuers in
respect of the Debt Securities of such series and this Indenture may be served. The Issuers will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers 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 

  
 24 








 
may be made or served at the office of the Trustee where its corporate trust business is principally administered in the United States, and the Issuers hereby appoint the Trustee as their agent
to receive all presentations, surrenders, notices and demands. 
 The Issuers may also from time to time designate different or additional
offices or agencies to be maintained for such purposes (in or outside of such Place of Payment), and may from time to time rescind any such designation; provided, however, that no such designation or rescission shall in any manner relieve the
Issuers of their obligations described in the preceding paragraph. The Issuers will give prompt written notice to the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or
additional office or agency. 
 Section 4.03 Appointment to Fill a Vacancy in the Office of Trustee. The Issuers, whenever
necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.08, a Trustee, so that there shall at all times be a Trustee hereunder with respect to each series of Debt Securities. 

Section 4.04 Duties of Paying Agents, etc. 

(a) The Issuers shall cause each paying agent, if any, other than the Trustee, to execute and deliver to the Trustee an instrument in which
such agent shall agree with the Trustee, subject to the provisions of this Section 4.04, 
 (i) that it will hold all
sums held by it as such agent for the payment of the principal of, and premium, if any, or interest on, the Debt Securities of any series (whether such sums have been paid to it by the Issuers or by any other obligor on the Debt Securities of such
series) in trust for the benefit of the Holders of the Debt Securities of such series; 
 (ii) that it will give the Trustee
notice of any failure by the Issuers (or by any other obligor on the Debt Securities of such series) to make any payment of the principal of, and premium, if any, or interest on, the Debt Securities of such series when the same shall be due and
payable; and 
 (iii) that it will at any time during the continuance of an Event of Default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held by it as such agent. 
 (b) If either of the Issuers shall act as its own paying
agent, it will, on or before each due date of the principal of, and premium, if any, or interest on, the Debt Securities of any series, set aside, segregate and hold in trust for the benefit of the Holders of the Debt Securities of such series a sum
sufficient to pay such principal, premium, if any, or interest so becoming due. The Issuers will promptly notify the Trustee of any failure by either of the Issuers to take such action or the failure by any other obligor on such Debt Securities to
make any payment of the principal of, and premium, if any, or interest on, such Debt Securities when the same shall be due and payable. 

  
 25 








 (c) Anything in this Section 4.04 to the contrary notwithstanding, either of the Issuers
may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the Trustee all sums held in trust by it or any paying agent, as required by this Section 4.04,
such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by such Issuer or such paying agent. 
 (d)
Whenever the Issuers shall have one or more paying agents with respect to any series of Debt Securities, they will, prior to each due date of the principal of, and premium, if any, or interest on, any Debt Securities of such series, deposit with any
such paying agent a sum sufficient to pay the principal, premium or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and (unless any such paying agent is the Trustee) the Issuers will promptly
notify the Trustee of its action or failure so to act. 
 (e) Anything in this Section 4.04 to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section 4.04 is subject to the provisions of Section 11.05. 

Section 4.05 SEC Reports; Financial Statements. 

(a) The Partnership shall, so long as any of the Debt Securities are Outstanding, file with the Trustee, within 30 days after it files the
same with the SEC, copies of the annual reports and the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may by rules and regulations prescribe) that the Partnership is required to file with the
SEC pursuant to Section 13 or 15(d) of the Exchange Act. If the Partnership is not subject to the requirements of such Section 13 or 15(d), the Partnership shall file with the Trustee, within 30 days after it would have been required to
file the same with the SEC, financial statements, including any notes thereto (and with respect to annual reports, an auditors’ report by a firm of established national reputation), and a “Management’s Discussion and Analysis of
Financial Condition and Results of Operations,” both comparable to that which the Partnership would have been required to include in such annual reports, information, documents or other reports if the Partnership had been subject to the
requirements of such Section 13 or 15 (d). The Issuers shall also comply with the provisions of TIA Section 314(a). 
 (b) The
Partnership shall provide the Trustee with a sufficient number of copies of all reports and other documents and information that the Trustee may be required to deliver to Holders under this Section. 

(c) The Partnership shall, so long as any of the Debt Securities are Outstanding, deliver to the Trustee, within 30 days of any Officer of the
Partnership becoming aware of the occurrence of any Event of Default, an Officers’ Certificate specifying such Event of Default and what action the Partnership is taking or proposes to take with respect thereto. 

Section 4.06 Compliance Certificate. 

(a) Each of the Issuers and any Subsidiary Guarantor shall, so long as any of the Debt Securities are Outstanding, deliver to the Trustee,
within 120 days after the end of each fiscal year of the Partnership, an Officers’ Certificate stating that a review of the activities of the Partnership and its Subsidiaries during the preceding fiscal year has been made under the supervision
of the Officers signing the certificate with a view to determining whether each of the 

  
 26 








 
Issuers and any Subsidiary Guarantor has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that
to the best of his knowledge each of the Issuers and any Subsidiary Guarantor has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms,
provisions and conditions hereof, without regard to any grace period or requirement of notice required by this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which such
Officer may have knowledge and what action the Issuers or any Subsidiary Guarantor is taking or proposes to take with respect thereto). 

(b) The Partnership shall, so long as any of the Debt Securities are Outstanding, deliver to the Trustee within 30 days after the occurrence
of any Default or Event of Default under this Indenture, written notice (which need not be an Officers’ Certificate) specifying such Default or Event of Default, the status thereof and what action the Partnership is taking or proposes to take
with respect thereto. 
 Section 4.07 Further Instruments and Acts. The Partnership will, upon request of the Trustee, execute
and deliver such further instruments and do such further acts as may reasonably be necessary or proper to carry out more effectually the purposes of this Indenture. 

Section 4.08 Existence. Except as permitted by Article X hereof, the Partnership shall do or cause to be done all things necessary
to preserve and keep in full force and effect its existence and all rights (charter and statutory) and franchises of the Partnership, provided that the Partnership shall not be required to preserve any such right or franchise, if the Partnership
shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Partnership. 
 Section 4.09
Maintenance of Properties. The Partnership shall cause all properties owned by the Partnership or any of its Subsidiaries or used or held for use in the conduct of its business or the business of any such Subsidiary to be maintained and kept
in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the
judgment of the Partnership may be necessary so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided that nothing in this Section shall prevent the Partnership from discontinuing
the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Partnership, desirable in the conduct of its business or the business of any such Subsidiary and not disadvantageous in any material respect to
the Holders. 
 Section 4.10 Payment of Taxes and Other Claims. The Partnership shall pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, (i) all taxes, assessments and governmental charges levied or imposed upon the Partnership or any of its Subsidiaries or upon the income, profits or property of the Partnership or any of its
Subsidiaries, and (ii) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a Lien upon the property of the Partnership or any of its Subsidiaries; provided that the Partnership shall not be required to pay
or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by appropriate proceedings.

 Section 4.11 Waiver of Certain Covenants. The Issuers and the Subsidiary Guarantors
may, with respect to the Debt Securities of any series, omit in any particular instance to comply with any covenant set forth in this Article IV (except Sections 4.01 through 4.08) or made applicable to such Debt Securities pursuant to
Section 2.03, if, before or after the time for such compliance, the Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected, waive such compliance in such instance with such covenant, but
no such waiver shall extend to or affect such covenant except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Issuers and the Subsidiary Guarantors and the duties of the Trustee in respect of
any such covenant shall remain in full force and effect. 
 ARTICLE V 

HOLDERS’ LISTS AND REPORTS BY THE TRUSTEE 

Section 5.01 Issuers to Furnish Trustee Information as to Names and Addresses of Holders; Preservation of Information. The Issuers
covenant and agree that they will furnish or cause to be furnished to the Trustee with respect to the Debt Securities of each series: 
 (a)
not more than 10 days after each record date with respect to the payment of interest, if any, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such record date, and 

(b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Issuers of any such request, a list of
similar form and contents as of a date not more than 15 days prior to the time such list is furnished; 
 provided, however, that so long as the Trustee
shall be the Registrar, such lists shall not be required to be furnished. 
 The Trustee shall preserve, in as current a form as is
reasonably practicable, all information as to the names and addresses of the Holders (i) contained in the most recent list furnished to it as provided in this Section 5.01 or (ii) received by it in the capacity of paying agent or
Registrar (if so acting) hereunder. 
 The Trustee may destroy any list furnished to it as provided in this Section 5.01 upon receipt
of a new list so furnished. 
 Section 5.02 Communications to Holders. Holders may communicate pursuant to Section 312(b) of the
TIA with other Holders with respect to their rights under this Indenture or the Debt Securities. The Issuers, the Trustee, the Registrar and anyone else shall have the protection of Section 312(c) of the TIA. 

Section 5.03 Reports by Trustee. Within 60 days after each January 31, beginning with the first January 31 following the
date of this Indenture, and in any event on or before April 1 in each year, the Trustee shall mail to Holders a brief report dated as of such January 31 that 

  
 28 








 
complies with TIA Section 313 (a); provided, however, that if no event described in TIA Section 313 (a) has occurred within the twelve months preceding the reporting date, no report
need be transmitted. The Trustee also shall comply with TIA Section 313 (b). 
 Reports pursuant to this Section 5.03 shall be
transmitted by mail: 
 (a) to all Holders, as the names and addresses of such Holders appear in the Debt Security Register; and 

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

interest upon any Debt Securities of that series as and when the same shall become due and payable, and continuance of such default for a period of 60 days; or

Securities, in this Indenture with respect to such series or in any supplemental Indenture with respect to such series (other than a covenant a default in the performance of which is elsewhere in this Section specifically dealt with), continuing, in
the case of this clause (ii), for a period of 30 days after the date on which written notice specifying such failure and requiring the Issuers, or if applicable, the Subsidiary Guarantors, to remedy the same shall have been given to the Issuers, or
if applicable, the Subsidiary Guarantors, by the Trustee or to the Issuers, or if applicable, the Subsidiary Guarantors, and the Trustee by the Holders of at least 25% in aggregate principal amount of the Debt Securities of that series at the time
Outstanding; or 
 (e) either of the Issuers, or if any series of Debt Securities Outstanding under this Indenture is entitled to the
benefits of the Guarantee, any of the Subsidiary Guarantors, pursuant to or within the meaning of any Bankruptcy Law, 
 (i)
commences a voluntary case; 
 (ii) consents to the entry of an order for relief against it in an involuntary case; 

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

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

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

(i) is for relief against either of the Issuers, or if any series of Debt Securities Outstanding under this Indenture is
entitled to the benefits of the Guarantee, any of the Subsidiary Guarantors, as debtor in an involuntary case; 
 (ii)

property of either of the Issuers, or if applicable, any of the Subsidiary Guarantors; or 
 (iii) orders the liquidation of
either of the Issuers, or if any series of Debt Securities Outstanding under this Indenture is entitled to the benefits of the Guarantee, any of the Subsidiary Guarantors; 

and the order or decree remains unstayed and in effect for 60 days; 

  
 30 








 (g) if any series of Debt Securities Outstanding under this Indenture is entitled to the benefits
of the Guarantee, the Guarantee of any of the Subsidiary Guarantors ceases to be in full force and effect with respect to Debt Securities of that series (except as otherwise provided in this Indenture) or is declared null and void in a judicial
proceeding or any of the Subsidiary Guarantors denies or disaffirms its obligations under this Indenture or such Guarantee; or 
 (h) any
other Event of Default provided with respect to Debt Securities of that series; 
 then and in each and every case that an Event of Default described in
clause (a), (b), (c), (d), (g), or (h) with respect to Debt Securities of that series at the time Outstanding occurs and is continuing, unless the principal of, premium, if any, and accrued and unpaid interest on all the Debt Securities of that
series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Debt Securities of that series then Outstanding hereunder, by notice in writing to the Issuers (and to the
Trustee if given by Holders), may declare the principal of (or, if the Debt Securities of that series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms of that series), premium, if
any, and interest on all the Debt Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and shall be immediately due and payable, anything in this Indenture or in the Debt Securities of that
series contained to the contrary notwithstanding. If an Event of Default described in clause (e) or (f) occurs with respect to either of the Issuers, then and in each and every such case, unless the principal of and accrued and unpaid interest
on all the Debt Securities shall have become due and payable, the principal of (or, if the Debt Securities of that series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms thereof),
premium, if any, and interest on all the Debt Securities then Outstanding hereunder shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders, anything in this Indenture
or in the Debt Securities contained to the contrary notwithstanding. 
 The Holders of a majority in aggregate principal amount of the Debt
Securities of a particular series by written notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction already rendered and if all
existing Events of Default with respect to that series have been cured or waived except nonpayment of principal, premium, if any, or interest that has become due solely because of acceleration. Upon any such rescission, the parties hereto shall be
restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the parties hereto shall continue as though no such proceeding had been taken. 

Section 6.02 Collection of Debt by Trustee, etc. If an Event of Default occurs and is continuing, the Trustee, in its own name and
as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of the sums so due and unpaid or enforce the performance of any provision of the Debt Securities of the
affected series or this Indenture, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment or final decree against any of the Subsidiary Guarantors or the Issuers or any other obligor upon the
Debt Securities of such series (and collect in the manner provided by law out of the property of any of the Subsidiary Guarantors or the Issuers or any other obligor upon the Debt Securities of such series wherever situated the moneys adjudged or
decreed to be payable). 

  
 31 








 In case there shall be pending proceedings for the bankruptcy or for the reorganization of any of
the Subsidiary Guarantors or the Issuers or any other obligor upon the Debt Securities of any series under any Bankruptcy Law, or in case a Custodian shall have been appointed for its property, or in case of any other similar judicial proceedings
relative to any of the Subsidiary Guarantors or the Issuers or any other obligor upon the Debt Securities of any series, its creditors or its property, the Trustee, irrespective of whether the principal of Debt Securities of any series shall then be
due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such
proceedings or otherwise, to file and prove a claim or claims for the whole amount of principal, premium, if any, and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion of the principal
amount as may be specified in the terms of such series) owing and unpaid in respect of the Debt Securities of such series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for reasonable compensation to the Trustee, its agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad
faith) and of the Holders thereof allowed in any such judicial proceedings relative to any of the Subsidiary Guarantors or the Issuers, or any other obligor upon the Debt Securities of such series, its creditors or its property, and to collect and
receive any moneys or other property payable or deliverable on any such claims, and to distribute all amounts received with respect to the claims of such Holders and of the Trustee on their behalf, and any receiver, assignee or trustee in bankruptcy
or reorganization is hereby authorized by each of such Holders to make payments to the Trustee, and, in the event that the Trustee shall consent to the making of payments directly to such Holders, to pay to the Trustee such amount as shall be
sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other reasonable expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith. 

All rights of action and of asserting claims under this Indenture, or under any of the Debt Securities of any series, may be enforced by the
Trustee without the possession of any such Debt Securities, or the production thereof in any trial or other proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment (except for any amounts payable to the Trustee pursuant to Section 7.06) shall be for the ratable benefit of the Holders of all the Debt Securities in respect of which such action was taken. 

In case of an Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or
agreement contained in this Indenture or in aid of the exercise of any power granted in this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 

  
 32 








 Section 6.03 Application of Moneys Collected by Trustee. Any moneys or other property
collected by the Trustee pursuant to Section 6.02 with respect to Debt Securities of any series shall be applied in the order following, at the date or dates fixed by the Trustee for the distribution of such moneys or other property, upon
presentation of the several Debt Securities of such series in respect of which moneys or other property have been collected, and the notation thereon of the payment, if only partially paid, and upon surrender thereof if fully paid: 

FIRST: To the payment of all money due the Trustee pursuant to Section 7.06; 

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

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

Section 6.04 Limitation on Suits by Holders. No Holder of any Debt Security of any series shall have any right by virtue or by
availing of any provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other
remedy hereunder, unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 25% in
aggregate principal amount of the 

  
 33 








 
Outstanding Debt Securities of that series shall have made written request upon the Trustee to institute such action or proceedings in respect of such Event of Default in its own name as Trustee
hereunder and shall have offered to the Trustee such reasonable indemnity or security as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice,
request and offer of indemnity or security shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.06; it being understood
and intended, and being expressly covenanted by the Holder of every Debt Security with every other Holder and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of this
Indenture to affect, disturb or prejudice the rights of any Holders, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the
equal, ratable and common benefit of all such Holders. For the protection and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity.

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

  
 34 








 
the Trustee to take any action deemed proper by the Trustee and which is not inconsistent with such direction by such Holders. The Holders of a majority in aggregate principal amount of the Debt
Securities of any series at the time Outstanding may on behalf of the Holders of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series, except a Default or Event of Default in the
payment of the principal of, and premium, if any, or interest on, any of the Debt Securities and a Default or Event of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected
thereby. In case of any such waiver, such Default shall cease to exist, any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture, and the Subsidiary Guarantors, the Issuers, the Trustee and the
Holders of the Debt Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent
thereon. 
 Section 6.07 Trustee to Give Notice of Events of Defaults Known to It, but May Withhold Such Notice in Certain
Circumstances. The Trustee shall, within 90 days after the occurrence of an Event of Default, or if later, within 30 days after the Trustee obtains actual knowledge of the Event of Default, with respect to a series of Debt Securities give to the
Holders thereof, in the manner provided in Section 13.03, notice of all Events of Default with respect to such series known to the Trustee, unless such Events of Default shall have been cured or waived before the giving of such notice;
provided, that, except in the case of an Event of Default in the payment of the principal of, or premium, if any, or interest on, any of the Debt Securities of such series or in the making of any sinking fund payment with respect to the Debt
Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive committee or a committee of directors or responsible officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Holders thereof. 
 Section 6.08 Requirement of an Undertaking to Pay
Costs in Certain Suits under the Indenture or Against the Trustee. All parties to this Indenture agree, and each Holder of any Debt Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require,
in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of
such suit in the manner and to the extent provided in the TIA, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section 6.08 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding
in the aggregate more than 25 percent in principal amount of the Outstanding Debt Securities of that series or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any
Debt Security on or after the due date for such payment expressed in such Debt Security. 

  
 35 








 ARTICLE VII 

CONCERNING THE TRUSTEE 

Section 7.01 Certain Duties and Responsibilities. The Trustee, prior to the occurrence of an Event of Default and after the curing
or waiving of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs. 

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, its own bad faith or its own willful misconduct, except that: 
 (a) this paragraph shall not be construed to limit the
effect of the first paragraph of this Section 7.01; and 
 (b) prior to the occurrence of an Event of Default with respect to the Debt
Securities of a series and after the curing or waiving of all Events of Default with respect to such series which may have occurred: 

(i) the duties and obligations of the Trustee with respect to Debt Securities of any series shall be determined solely by the
express provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations with respect to such series as are specifically set forth in this Indenture, and no implied covenants or obligations
with respect to such series shall be read into this Indenture against the Trustee; 
 (ii) in the absence of bad faith on the
part of the Trustee, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this
Indenture; but in the case of any such certificates or opinions 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 conform to
the requirements of this Indenture; but the Trustee shall examine the evidence furnished to it pursuant to Sections 4.05 and 4.06 to determine whether or not such evidence conforms to the requirement of this Indenture; 

(iii) the Trustee shall not be liable for an error of judgment made in good faith by a responsible officer, unless it shall be
proved that the Trustee was negligent in ascertaining the pertinent facts; and 
 (iv) the Trustee shall not be liable with
respect to any action taken or omitted to be taken by it with respect to Debt Securities of any series in good faith in accordance with the direction of the Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of
that series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to Debt Securities of such
series. 

  
 36 








 None of the provisions of this Indenture shall require the Trustee to expend or risk its own
funds or otherwise incur any personal financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there shall be reasonable grounds for believing that repayment of such funds or
adequate indemnity against such risk or liability is not reasonably assured to it. 
 Whether or not therein expressly so provided, every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

Section 7.02 Certain Rights of Trustee. Except as otherwise provided in Section 7.01: 

(a) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, note or other paper or document (whether in its original or facsimile form) believed by it to be genuine and to have been signed or presented by the proper party or
parties; 
 (b) any request, direction, order or demand of either of the Issuers mentioned herein shall be sufficiently; evidenced by an
Issuer Order (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors of an Issuer may be evidenced to the Trustee by a copy thereof certified by its Secretary or an Assistant
Secretary; 
 (c) the Trustee may consult with counsel, and the advice of such counsel or any Opinion of Counsel shall be full and complete
authorization and protection in respect of any action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or
direction of any of the Holders of Debt Securities of any series pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which
may be incurred therein or thereby; 
 (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and
reasonably believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 
 (f) prior to
the occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement,
instrument, opinion, report, notice, request, direction, consent, order, approval or other paper or document, unless requested in writing to do so by the Holders of a majority in aggregate principal amount of the then Outstanding Debt Securities of
a series affected by such matter; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be 

  
 37 








 
incurred by it in the making of such investigation is not, in the opinion of the Trustee, reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the
Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding, and the reasonable expense of every such investigation shall be paid by the Issuers or, if paid by the Trustee, shall be repaid by
the Issuers upon demand; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of any agent or attorney appointed by it with due care hereunder; and 

(h) if any property other than cash shall at any time be subject to a Lien in favor of the Holders, the Trustee, if and to the extent
authorized by a receivership or bankruptcy court of competent jurisdiction or by the supplemental instrument subjecting such property to such Lien, shall be entitled to make advances for the purpose of preserving such property or of discharging tax
Liens or other prior Liens or encumbrances thereon. 
 Section 7.03 Trustee Not Liable for Recitals in Indenture or in Debt
Securities. The recitals contained herein, in the Debt Securities (except the Trustee’s certificate of authentication) shall be taken as the statements of the Issuers, and the Trustee assumes no responsibility for the correctness of the
same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debt Securities of any series, except that the Trustee represents that it is duly authorized to execute and deliver this Indenture, authenticate
the Debt Securities and perform its obligations hereunder, and that the statements made by it or to be made by it in a Statement of Eligibility and Qualification on Form T-1 supplied to the Issuers are true
and accurate. The Trustee shall not be accountable for the use or application by the Issuers of any of the Debt Securities or of the proceeds thereof. 

Section 7.04 Trustee, Paying Agent or Registrar May Own Debt Securities. The Trustee or any paying agent or Registrar, in
its individual or any other capacity, may become the owner or pledgee of Debt Securities and subject to the provisions of the TIA relating to conflicts of interest and preferential claims may otherwise deal with the Issuers with the same rights it
would have if it were not Trustee, paying agent or Registrar. 
 Section 7.05 Moneys Received by Trustee to Be Held in Trust.
Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated from other funds except
to the extent required by law. The Trustee shall be under no liability for interest on any moneys received by it hereunder. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys shall be paid
from time to time to the Issuers upon an Issuer Order. 
 Section 7.06 Compensation and Reimbursement. The Issuers covenant and
agree to pay in Dollars to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder (which shall not be limited by any provision of law in regard to the compensation of a
trustee of an express trust), and, except as otherwise expressly provided herein, the Issuers will pay or reimburse in Dollars the Trustee 

  
 38 








 
upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable
compensation and the expenses and disbursements of its agents, attorneys and counsel and of all Persons not regularly in its employ), including without limitation, Section 6.02, except any such expense, disbursement or advances as may arise
from its negligence, willful misconduct or bad faith. The Issuers also covenant to indemnify in Dollars the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence, willful misconduct or bad faith on
the part of the Trustee, arising out of or in connection with the acceptance or administration of this trust or trusts hereunder, including the reasonable costs and expenses of defending itself against any claim of liability in connection with the
exercise or performance of any of its powers or duties hereunder. The obligations of the Issuers under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements and advances shall
constitute additional Debt hereunder and shall survive the satisfaction and discharge of this Indenture. The Issuers and the Holders agree that such additional Debt shall be secured by a Lien prior to that of the Debt Securities upon all property
and funds held or collected by the Trustee, as such, except funds held in trust for the payment of principal of, and premium, if any, or interest on, particular Debt Securities. 

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(e) or (f) occurs, the expenses
and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law. 
 Section 7.07
Right of Trustee to Rely on an Officers’ Certificate Where No Other Evidence Specifically Prescribed. Except as otherwise provided in Section 7.01, whenever in the administration of the provisions of this Indenture the
Trustee shall deem it necessary or desirable that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the
absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee and such certificate, in the absence of negligence or bad faith on the part
of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 

Section 7.08 Separate Trustee; Replacement of Trustee. The Issuers may, but need not, appoint a separate Trustee for any one or
more series of Debt Securities. The Trustee may resign with respect to one or more or all series of Debt Securities at any time by giving notice to the Issuers. The Holders of a majority in aggregate principal amount of the Debt Securities of a
particular series may remove the Trustee for such series and only such series by so notifying the Trustee and may appoint a successor Trustee. The Issuers shall remove the Trustee if: 

(a) the Trustee fails to comply with Section 7.10; 

(b) the Trustee is adjudged bankrupt or insolvent; 

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

(d) the Trustee otherwise becomes incapable of acting. 

  
 39 








 If the Trustee resigns, is removed by the Issuers or by the Holders of a majority in aggregate
principal amount of the Debt Securities of a particular series and such Holders do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to
herein as the retiring Trustee), the Issuers shall promptly appoint a successor Trustee. No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor
Trustee in accordance with the applicable requirements of this Section 7.08. 
 A successor Trustee shall deliver a written acceptance
of its appointment to the retiring Trustee and to the Issuers. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture. The successor Trustee shall mail a notice of its succession to Holders of Debt Securities of each applicable series. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the
Lien provided for in Section 7.06. 
 If a successor Trustee does not take office within 60 days after the retiring Trustee gives
notice of resignation or is removed, the retiring Trustee or the Holders of 25% in aggregate principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment of a successor Trustee
for the Debt Securities of such series. 
 If the Trustee fails to comply with Section 7.10, any Holder of Debt Securities of any
applicable series may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series. 

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

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

  
 40 








 In case at the time such successor or successors to the Trustee by merger, conversion,
consolidation or transfer shall succeed to the trusts created by this Indenture any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any
predecessor Trustee, and deliver such Debt Securities so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of
any predecessor hereunder or in the name of the successor to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Debt Securities or in this Indenture provided that the certificate of the Trustee
shall have. 
 Section 7.10 Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section
310(a) of the TIA. The Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Debt Securities of a particular series or Person directly or
indirectly controlling, controlled by or under common control with such obligor shall serve as Trustee for the Debt Securities of such series. The Trustee shall comply with Section 310(b) of the TIA; provided, however, that there shall be excluded
from the operation of Section 310(b)(1) of the TIA this Indenture or any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Issuers are outstanding if the requirements for
such exclusion set forth in Section 310(b)(1) of the TIA are met. 
 Section 7.11 Preferential Collection of Claims
Against Issuers. The Trustee shall comply with Section 311(a) of the TIA, excluding any creditor relationship listed in Section 311(b) of the TIA. A Trustee who has resigned or been removed shall be subject to Section 311(a) of the
TIA to the extent indicated therein. 
 Section 7.12 Compliance with Tax Laws. The Trustee hereby agrees to comply with all U.S.
Federal income tax information reporting and withholding requirements applicable to it with respect to payments of premium (if any) and interest on the Debt Securities, whether acting as Trustee, Registrar, paying agent or otherwise with respect to
the Debt Securities. 
 ARTICLE VIII 

CONCERNING THE HOLDERS 

Section 8.01 Evidence of Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage
in aggregate principal amount of the Debt Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action) the fact that at the
time of taking any such action the Holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in
writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Section 5.02, (c) by a combination of such instrument or instruments and any such record
of such a meeting of Holders or (d) in the case of Debt Securities evidenced by a Global Security, by any electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable
procedures. 

  
 41 








 Section 8.02 Proof of Execution of Instruments and of Holding of Debt Securities.
Subject to the provisions of Sections 7.01, 7.02 and 13.09, proof of the execution of any instrument by a Holder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the
Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Debt Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series. The Trustee may require such
additional proof of any matter referred to in this Section 8.02 as it shall deem necessary. 
 Section 8.03 Who May Be Deemed
Owner of Debt Securities. Prior to due presentment for registration of transfer of any Debt Security, the Issuers, the Subsidiary Guarantors, the Trustee, any paying agent and any Registrar may deem and treat the Person in whose name any Debt
Security shall be registered upon the books of the Issuers as the absolute owner of such Debt Security (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of
receiving payment of or on account of the principal of and premium, if any, and (subject to Section 2.12) interest on such Debt Security and for all other purposes, and none of the Issuers, the Subsidiary Guarantors or the Trustee nor any
paying agent nor any Registrar shall be affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, or upon his order, shall be valid and, to the extent of the sum or sums so paid, effectual to
satisfy and discharge the liability for moneys payable upon any such Debt Security. 
 None of the Issuers, the Subsidiary Guarantors, the
Trustee, any paying agent or any Registrar will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests. 
 Section 8.04 Instruments Executed by Holders Bind Future
Holders. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 8.01, of the taking of any action by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series
specified in this Indenture in connection with such action and subject to the following paragraph, any Holder of a Debt Security which is shown by the evidence to be included in the Debt Securities the Holders of which have consented to such action
may, by filing written notice with the Trustee at its corporate trust office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Debt Security. Except as aforesaid any such action taken by the
Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Debt Security and of any Debt Security issued upon transfer thereof or in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities. Any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this
Indenture in connection with such action shall be conclusively binding upon the Issuers, the Subsidiary Guarantors, the Trustee and the Holders of all the Debt Securities of such series. 

  
 42 








 The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining
the Holders of Debt Securities entitled to give their consent or take any other action required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons
who were Holders of Debt Securities at such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such
Persons continue to be Holders of Debt Securities after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless the consent of the Holders of the percentage in aggregate principal amount of
the Debt Securities of such series specified in this Indenture shall have been received within such 120-day period. 

ARTICLE IX 
 SUPPLEMENTAL
INDENTURES 
 Section 9.01 Purposes for Which Supplemental Indenture May Be Entered into Without Consent of Holders. The
Issuers, any Subsidiary Guarantors and the Trustee may from time to time and at any time, without the consent of Holders, enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the TIA as in force at the
date of the execution thereof) for one or more of the following purposes: 
 (a) to evidence the succession pursuant to Article X of another
Person to either of the Issuers, or successive successions, and the assumption by the Successor Company (as defined in Section 10.01) of the covenants, agreements and obligations of its predecessor Issuer in this Indenture and in the Debt
Securities; 
 (b) to surrender any right or power herein conferred upon the Issuers or the Subsidiary Guarantors, to add to the covenants
of the Issuers or the Subsidiary Guarantors such further covenants, restrictions, conditions or provisions for the protection of the Holders of all or any series of Debt Securities (and if such covenants are to be for the benefit of less than all
series of Debt Securities, stating that such covenants are expressly being included solely for the benefit of such series) as the Board of Directors shall consider to be for the protection of the Holders of such Debt Securities, and to make the
occurrence, or the occurrence and continuance, of a Default in any of such additional covenants, restrictions, conditions or provisions a Default or an Event of Default permitting the enforcement of all or any of the several remedies provided in
this Indenture; provided, that in respect of any such additional covenant, restriction, condition or provision such supplemental Indenture may provide for a particular period of grace after Default (which period may be shorter or longer than that
allowed in the case of other Defaults) or may provide for an immediate enforcement upon such Default or may limit the remedies available to the Trustee upon such Default or may limit the right of the Holders of a majority in aggregate principal
amount of any or all series of Debt Securities to waive such Default; 
 (c) to cure any ambiguity or omission or to correct or supplement
any provision contained herein, in any supplemental Indenture or in any Debt Securities of any series that may be defective or inconsistent with any other provision contained herein, in any supplemental Indenture or in the Debt Securities of such
series; 

  
 43 








 (d) to permit the qualification of this Indenture or any Indenture supplemental hereto under the
TIA as then in effect, except that nothing herein contained shall permit or authorize the inclusion in any Indenture supplemental hereto of the provisions referred to in Section 316(a)(2) of the TIA; 

(e) to permit or facilitate the issuance of Debt Securities of any series in uncertificated form; 

(f) to reflect the release of any Subsidiary Guarantor in accordance with Article XIV; 

(g) to add Subsidiary Guarantors with respect to any or all of the Debt Securities or to secure any or all of the Debt Securities or the
Guarantee; 
 (h) to make any change that does not adversely affect the rights hereunder of any Holder; 

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

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

(k) to establish the form or terms of Debt Securities of any series as permitted by Sections 2.01 and 2.03. 

The Trustee is hereby authorized to join with the Issuers and the Subsidiary Guarantors in the execution of any such supplemental Indenture,
to make any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any
such supplemental Indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any
supplemental Indenture authorized by the provisions of this Section 9.01 may be executed by the Issuers, the Subsidiary Guarantors and the Trustee without the consent of the Holders of any of the Debt Securities at the time Outstanding,
notwithstanding any of the provisions of Section 9.02. 
 Section 9.02 Modification of Indenture with Consent of Holders of
Debt Securities. Without notice to any Holder but with the consent (evidenced as provided in Section 8.01) of the Holders of a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected by such
supplemental Indenture (including consents obtained in connection with a 

  
 44 








 
tender offer or exchange offer for any such series of Debt Securities), (i) the Issuers and the Subsidiary Guarantors, when authorized by resolutions of each Issuer’s Board of Directors, and
the Trustee may from time to time and at any time enter into an Indenture or Indentures supplemental hereto (which shall conform to the provisions of the TIA as in force at the date of execution thereof) for the purpose of adding any provisions to
or changing in any manner or eliminating any of the provisions of this Indenture or of any supplemental Indenture or of modifying in any manner the rights of the Holders of the Debt Securities of such series, and (ii) subject to Sections 6.04
and 6.06, any existing Default or Event of Default or compliance with any provision of this Indenture or the Debt Securities of such series may be waived; provided, that no such supplemental Indenture or waiver, without the consent of the Holders of
each Debt Security so affected, shall: reduce the rate of or extend the time for payment of interest on any Debt Security; reduce the principal of or extend the Stated Maturity of any Debt Security; reduce any premium payable upon the redemption of
any Debt Security or change the time at which any Debt Security may or shall be redeemed in accordance with Article III; make any Debt Security payable in currency other than that stated in such Debt Security; impair the right of any Holder to
receive payment of premium, if any, principal of and interest on such Holder’s Debt Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Debt Securities;
release any security that may have been granted in respect of the Debt Securities, other than in accordance with this Indenture; make any change in Section 6.06 or this Section 9.02 (except to increase any percentage set forth therein or
herein); except as provided in Section 11.02(b) or Section 14.04, release the Subsidiary Guarantors other than as provided in this Indenture or modify the Guarantee in any manner adverse to the Holders; waive any redemption payment with respect
to any Debt Security (except as may be permitted by Sections 2.01 and 2.03 in the case of a particular series of Debt Securities); or make any change in this Section 9.02 (except to increase any percentage set forth herein). 

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

After an amendment under this Section 9.02 requiring the consent of the Holders of any series of Debt Securities becomes effective, the
Issuers shall mail to Holders of that series of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to any such Holders, or any defect therein, shall not impair or affect the
validity of an amendment under this Section 9.02 with respect to other Holders. 

  
 45 








 Section 9.03 Effect of Supplemental Indentures. Upon the execution of any
supplemental Indenture pursuant to the provisions of this Article IX, this Indenture shall be and be deemed to be modified and amended in accordance therewith and the respective rights, limitations of rights, obligations, duties and immunities under
this Indenture of the Trustee, the Issuers, the Subsidiary Guarantors and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such modifications and amendments, and all the terms and conditions of
any such supplemental Indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 

The Trustee, subject to the provisions of Sections 7.01 and 7.02, may receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any such supplemental Indenture complies with the provisions of this Article IX. 
 Section 9.04 Debt
Securities May Bear Notation of Changes by Supplemental Indentures. Debt Securities of any series authenticated and delivered after the execution of any supplemental Indenture pursuant to the provisions of this Article IX may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental Indenture. New Debt Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such supplemental Indenture may be prepared and executed by the Issuers, authenticated by the Trustee and delivered in exchange for the Debt Securities of such series then
Outstanding. Failure to make the appropriate notation or to issue a new Debt Security of such series shall not affect the validity of such amendment. 

ARTICLE X 

CONSOLIDATION, MERGER, SALE OR CONVEYANCE 

Section 10.01 Consolidations and Mergers of the Issuers. Neither of the Issuers may consolidate or amalgamate with or merge with
or into any Person, or sell, convey, transfer, lease or otherwise dispose of all or substantially all its assets to any Person, whether in a single transaction or a series of related transactions, unless: (a) either (i) such Issuer shall be the
surviving Person in the case of a merger or (ii) the resulting, surviving or transferee Person if other than such Issuer (the “Successor Company”), shall be a partnership, limited liability company or corporation organized and
existing under the laws of the United States, any State thereof or the District of Columbia (provided that Finance Corp. may not consolidate or amalgamate with or merge into another Person other than a corporation satisfying such requirements so
long as the Partnership is not a corporation), and the Successor Company shall expressly assume, by an Indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of such Issuer
under this Indenture and the Debt Securities according to their tenor; (b) immediately after giving effect to such transaction or series of transactions (and treating any Debt which becomes an obligation of the Successor Company or any
Subsidiary of such Issuer as a result of such transaction as having been incurred by the Successor Company or such Subsidiary at the time of such transaction or series of transactions), no Default or Event of Default would occur or be continuing;
(c) if such Issuer is 

  
 46 








 
not the continuing Person, then each Subsidiary Guarantor, unless it has become the Successor Company, shall confirm that its Guarantee shall continue to apply to the obligations under the Debt
Securities and this Indenture; and (d) the Issuers shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger or disposition and such supplemental
Indenture (if any) comply with this Indenture. 
 Section 10.02 Rights and Duties of Successor Company. In case of any
consolidation, amalgamation or merger where such Issuer is not the continuing Person, or disposition of all or substantially all of the assets of such Issuer in accordance with Section 10.01, the Successor Company shall succeed to and be
substituted for such Issuer with the same effect as if it had been named herein as the respective party to this Indenture, and the predecessor entity shall be released from all liabilities and obligations under this Indenture and the Debt
Securities, except that no such release will occur in the case of a lease of all or substantially all of such Issuer’s assets. The Successor Company thereupon may cause to be signed, and may issue either in its own name or in the name of such
Issuer, any or all the Debt Securities issuable hereunder which theretofore shall not have been signed by or on behalf of such Issuer and delivered to the Trustee; and, upon the order of the Successor Company, instead of such Issuer, and subject to
all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Debt Securities which previously shall have been signed and delivered by or on behalf of such Issuer to the Trustee for
authentication, and any Debt Securities which the Successor Company thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Debt Securities so issued shall in all respects have the same legal rank and benefit under
this Indenture as the Debt Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all such Debt Securities had been issued at the date of the execution hereof. 

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

SATISFACTION AND DISCHARGE OF 

INDENTURE; DEFEASANCE; UNCLAIMED MONEYS 

Section 11.01 Applicability of Article. The provisions of this Article XI relating to discharge or defeasance of Debt Securities
shall be applicable to each series of Debt Securities except as otherwise specified pursuant to Section 2.03 for Debt Securities of such series. 

Section 11.02 Satisfaction and Discharge of Indenture; Defeasance. 

(a) If at any time the Issuers shall have delivered to the Trustee for cancellation all Debt Securities of any series theretofore
authenticated and delivered (other than any Debt Securities of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 and Debt Securities for whose payment money has
theretofore been deposited in trust and thereafter repaid to the Issuers as provided in Section 11.05) or all Debt Securities of such series not theretofore delivered to the Trustee for 

  
 47 








 
cancellation shall have become due and payable by reason of the giving of a notice of redemption or otherwise, or are by their terms to become due and payable within one year or are to be called
for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Issuers shall irrevocably deposit with the Trustee as trust funds the entire amount in cash sufficient, without
consideration of any investment of interest, to pay and discharge the entire indebtedness of all Debt Securities of such series not theretofore delivered to the Trustee for cancellation, for principal and premium, if any, and accrued interest to the
date of such deposit (in the case of Debt Securities that have become due and payable) or to the stated maturity or Redemption Date, as the case may be, and if in either case the Issuers shall also pay or cause to be paid all other sums payable
hereunder by the Issuers with respect to the Debt Securities of such series, then this Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of such Debt Securities herein expressly
provided for) with respect to the Debt Securities of such series, and the Trustee, on demand of the Issuers accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Issuers, shall execute proper
instruments acknowledging satisfaction of and discharging this Indenture with respect to the Debt Securities of such series. 
 (b) Subject
to Sections 11.02(c), 11.03 and 11.07, the Issuers at any time may terminate, with respect to Debt Securities of a particular series, all their obligations under the Debt Securities of such series and this Indenture with respect to the Debt
Securities of such series (“legal defeasance option”) or the operation of (w) Sections 4.09 and 4.10, (x) any covenant made applicable to such Debt Securities pursuant to Section 2.03, (y) Sections 6.01(d), (g) and (h) and
(z) as they relate to the Subsidiary Guarantors only, Sections 6.01(e) and (f) (“covenant defeasance option”). If the Issuers exercise either their legal defeasance option or their covenant defeasance option with respect to Debt
Securities of a particular series that are entitled to the benefit of the Guarantee, the Guarantee will terminate with respect to that series of Debt Securities. The Issuers may exercise their legal defeasance option notwithstanding their prior
exercise of their covenant defeasance option. 
 If the Issuers exercise their legal defeasance option, payment of the Debt Securities of
the defeased series may not be accelerated because of an Event of Default. If the Issuers exercise their covenant defeasance option, payment of the Debt Securities of the defeased series may not be accelerated because of an Event of Default
specified in Sections 6.01(d), (g) and (h) and, with respect to the Subsidiary Guarantors only, Sections 6.01(e) and (f). 
 Upon
satisfaction of the conditions set forth herein and upon request of the Issuers, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuers terminate. 

(c) Notwithstanding clauses (a) and (b) above, the Issuers’ obligations in Sections 2.07, 2.09, 4.02, 4.03, 4.04, the last sentence
of 4.05(a), 4.06(a), 5.01, 7.06, 11.05, 11.06 and 11.07 shall survive until the Debt Securities of the defeased series have been paid in full. Thereafter, the Issuers’ obligations in Sections 7.06, 11.05 and 11.06 shall survive. 

Section 11.03 Conditions of Defeasance. The Issuers may exercise their legal defeasance option or their covenant defeasance option
with respect to Debt Securities of a particular series only if: 
 (a) the Issuers irrevocably deposit in trust with the Trustee money or
U.S. Government Obligations for the payment of principal of, and premium, if any, and interest on, the Debt Securities of such series to final maturity or redemption, as the case may be; 

  
 48 








 (b) the Issuers deliver to the Trustee a certificate from a nationally recognized firm of
independent accountants expressing their opinion that the payments of principal and interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such times
and in such amounts as will be sufficient to pay the principal, premium, if any, and interest when due on all the Debt Securities of such series to final maturity or redemption, as the case may be; 

(c) 91 days pass after the deposit is made and during the 91-day period no Default specified in
Section 6.01(e) or (f) with respect to the Issuers occurs which is continuing at the end of the period; 
 (d) no Default has occurred
and is continuing on the date of such deposit and after giving effect thereto; 
 (e) the deposit does not constitute a default under any
other agreement binding on the Issuers; 
 (f) the Issuers deliver to the Trustee an Opinion of Counsel to the effect that the trust
resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 

(g) in the event of the legal defeasance option, the Issuers shall have delivered to the Trustee an Opinion of Counsel stating that the
Issuers have received from the Internal Revenue Service a ruling, or since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel
shall confirm that, the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the same
manner and at the same times as would have been the case if such defeasance had not occurred; 
 (h) in the event of the covenant defeasance
option, the Issuers shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such covenant
defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and 

(i) the Issuers deliver to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to
the defeasance and discharge of the Debt Securities of such series as contemplated by this Article XI have been complied with. 
 Before or
after a deposit, the Issuers may make arrangements satisfactory to the Trustee for the redemption of Debt Securities of such series at a future date in accordance with Article III. 

  
 49 








 Section 11.04 Application of Trust Money. The Trustee shall hold in trust money or
U.S. Government Obligations deposited with it pursuant to this Article XI. It shall apply the deposited money and the money from U.S. Government Obligations through any paying agent and in accordance with this Indenture to the payment of principal
of, and premium, if any, and interest on, the Debt Securities of the defeased series. 
 Section 11.05 Repayment to Issuers. The
Trustee and any paying agent shall promptly turn over to the Issuers upon request any excess money or securities held by them at any time. Subject to any applicable abandoned property law, the Trustee and any paying agent shall pay to the Issuers
upon request any money held by them for the payment of principal, premium or interest that remains unclaimed for two years, and, thereafter, Holders entitled to such money must look to the Issuers for payment as general creditors. 

Section 11.06 Indemnity for Government Obligations. The Issuers shall pay and shall indemnify the Trustee and the Holders against
any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations. 

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

ARTICLE XIV 
 GUARANTEE

 Section 14.01 Unconditional Guarantee. 

(a) Notwithstanding any provision of this Article XIV to the contrary, the provisions of this Article XIV shall be applicable only to, and
inure solely to the benefit of, the Debt Securities of any series designated, pursuant to Section 2.03, as entitled to the benefits of the Guarantee of each of the Subsidiary Guarantors. 

(b) For value received, each of the Subsidiary Guarantors hereby fully, unconditionally and absolutely guarantees (the “Guarantee”)
to the Holders and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the Debt Securities and all other amounts due and payable under this Indenture and the Debt Securities by the Issuers, when and
as such principal, premium, if any, and interest shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the Debt Securities and this Indenture,
subject to the limitations set forth in Section 14.03. 

  
 53 








 (c) Failing payment when due of any amount guaranteed pursuant to the Guarantee, for whatever
reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. The Guarantee hereunder is intended to be a general, unsecured, senior obligation of each of the Subsidiary Guarantors and will rank pari
passu in right of payment with all Debt of each Subsidiary Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantee. Each of the Subsidiary Guarantors hereby agrees that its obligations hereunder shall be
full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Debt Securities, the Guarantee (including the Guarantee of any other Subsidiary Guarantor) or this Indenture, the absence of any action to enforce
the same, any waiver or consent by any Holder of the Debt Securities with respect to any provisions hereof or thereof, the recovery of any judgment against either of the Issuers or any other Subsidiary Guarantor, or any action to enforce the same or
any other circumstances which might otherwise constitute a legal or equitable discharge or defense of any of the Subsidiary Guarantors. Each of the Subsidiary Guarantors hereby agrees that in the event of a default in payment of the principal of, or
premium, if any, or interest on the Debt Securities, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to
Section 6.04, by the Holders, on the terms and conditions set forth in this Indenture, directly against such Subsidiary Guarantor to enforce the Guarantee without first proceeding against either of the Issuers or any other Subsidiary Guarantor.

 (d) The obligations of each of the Subsidiary Guarantors under this Article XIV shall be as aforesaid full, unconditional and absolute
and shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (A) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change
in, any of the obligations and liabilities of any of the Issuers or the Subsidiary Guarantors contained in the Debt Securities or this Indenture, (B) any impairment, modification, release or limitation of the liability of any of the Issuers or
the Subsidiary Guarantors or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the
decision of any court, (C) the assertion or exercise by any of the Issuers, the Subsidiary Guarantors or the Trustee of any rights or remedies under the Debt Securities or this Indenture or their delay in or failure to assert or exercise any
such rights or remedies, (D) the assignment or the purported assignment of any property as security for the Debt Securities, including all or any part of the rights of any of the Issuers or the Subsidiary Guarantors under this Indenture,
(E) the extension of the time for payment by any of the Issuers or the Subsidiary Guarantors of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Debt Securities or this Indenture or of
the time for performance by any of the Issuers or the Subsidiary Guarantors of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (F) the modification or amendment
(whether material or otherwise) of any duty, agreement or obligation of any of the Issuers or the Subsidiary Guarantors set forth in this Indenture, (G) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or
substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting,
any of the Issuers or the Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the Debt Securities, the Guarantee or this Indenture in 

  
 54 








 
any such proceeding, (H) the release or discharge of any of the Issuers or the Subsidiary Guarantors from the performance or observance of any agreement, covenant, term or condition
contained in any of such instruments by operation of law, (I) the unenforceability of the Debt Securities, the Guarantee or this Indenture or (J) any other circumstances (other than payment in full or discharge of all amounts guaranteed
pursuant to the Guarantee) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 
 (e) Each of the
Subsidiary Guarantors hereby (A) waives diligence, presentment, demand of payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of any of the Issuers or the Subsidiary Guarantors, and all demands
whatsoever, (B) acknowledges that any agreement, instrument or document evidencing the Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document
evidencing the Guarantee without notice to it and (C) covenants that the Guarantee will not be discharged except by complete performance of the Guarantee. Each of the Subsidiary Guarantors further agrees that if at any time all or any part of
any payment theretofore applied by any Person to the Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of any of the Issuers or the Subsidiary
Guarantors, the Guarantee shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantee shall continue to be effective or be reinstated, as
the case may be, as though such application had not been made. 
 (f) Each of the Subsidiary Guarantors shall be subrogated to all rights of
the Holders and the Trustee against the Issuers in respect of any amounts paid by such Subsidiary Guarantor pursuant to the provisions of this Indenture, provided, however, that such Subsidiary Guarantor, shall not be entitled to enforce or to
receive any payments arising out of, or based upon, such right of subrogation until all of the Debt Securities and the Guarantee shall have been paid in full or discharged. 

Section 14.02 Execution and Delivery of Guarantee. To further evidence the Guarantee set forth in Section 14.01, each of the
Subsidiary Guarantors hereby agrees that a notation relating to such Guarantee, substantially in the form attached hereto as Annex A, shall be endorsed on each Debt Security entitled to the benefits of the Guarantee authenticated and delivered by
the Trustee and executed by either manual or facsimile signature of an Officer of such Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that the Guarantee set forth in Section 14.01 shall remain in full force and effect
notwithstanding any failure to endorse on each Debt Security a notation relating to the Guarantee. If any Officer of any Subsidiary Guarantor whose signature is on this Indenture or a Debt Security no longer holds that office at the time the Trustee
authenticates such Debt Security or at any time thereafter, the Guarantee of such Debt Security shall be valid nevertheless. The delivery of any Debt Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery
of the Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors. 
 Section 14.03 Limitation on Subsidiary
Guarantors’ Liability. Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Debt Security entitled to the benefits of the Guarantee hereby confirm that it is the intention of all such parties that the
guarantee by such Subsidiary Guarantor pursuant to the Guarantee not constitute a fraudulent transfer or 

  
 55 








 
conveyance for purposes of any Federal or state law. To effectuate the foregoing intention, the Holders of a Debt Security entitled to the benefits of the Guarantee and the Subsidiary Guarantors
hereby irrevocably agree that the obligations of each Subsidiary Guarantor under the Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and to any
collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under the Guarantee, not result in the obligations of such Subsidiary Guarantor under the Guarantee
constituting a fraudulent conveyance or fraudulent transfer under Federal or state law. 
 Section 14.04 Release of Subsidiary
Guarantors from Guarantee. 
 (a) Notwithstanding any other provisions of this Indenture, the Guarantee of any Subsidiary Guarantor may
be released upon the terms and subject to the conditions set forth in Section 11.02(b) and in this Section 14.04. Provided that no Default shall have occurred and shall be continuing under this Indenture, the Guarantee incurred by a Subsidiary
Guarantor pursuant to this Article XIV shall be unconditionally released and discharged (i) automatically upon any sale, exchange or transfer, whether by way of merger or otherwise, to any Person that is not an Affiliate of the Partnership, of
all of the Partnership’s direct or indirect limited partnership or other equity interests in such Subsidiary Guarantor (provided such sale, exchange or transfer is not prohibited by this Indenture) or (ii) upon the Issuers’ delivery
of a written notice to the Trustee of the release or discharge of all guarantees by such Subsidiary Guarantor of any Debt of the Issuers other than obligations arising under this Indenture and any Debt Securities issued hereunder, except a discharge
or release by or as a result of payment under such guarantees. 
 (b) The Trustee shall deliver an appropriate instrument evidencing any
release of a Subsidiary Guarantor from the Guarantee upon receipt of a written request of the Issuers accompanied by an Officers’ Certificate and an Opinion of Counsel to the effect that the Subsidiary Guarantor is entitled to such release in
accordance with the provisions of this Indenture. Any Subsidiary Guarantor not so released shall remain liable for the full amount of principal of (and premium, if any) and interest on the Debt Securities entitled to the benefits of the Guarantee as
provided in this Indenture, subject to the limitations of Section 14.03. 
 Section 14.05 Subsidiary Guarantor
Contribution. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors hereby agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a
“Funding Guarantor”) under the Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the net assets of each Subsidiary Guarantor (including the
Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Issuers’ obligations with respect to the Debt Securities or any other Subsidiary Guarantor’s obligations with respect to the
Guarantee. 
 The Trustee hereby accepts the trusts in this Indenture upon the terms and conditions herein set forth.
