Holder’s address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders of Registered
Securities is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder of a Registered Security shall affect the sufficiency of such notice with respect to other Holders of Registered
Securities given as provided herein. Any notice that is mailed in the manner herein provided shall be conclusively presumed to have been duly given or provided. In the case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

Where this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders of Securities shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action
taken in reliance upon such waiver.

Judgment Currency. 
 The Company and each Guarantor agrees, to the fullest extent that it may effectively do so under applicable law, that
(A) if for the purpose of obtaining judgment in any court it is necessary to convert the sum due in respect of (i) the principal of, or premium or interest, if any, or Additional Amounts on the Securities of any series or (ii) a
Guarantee (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance with normal banking procedures

enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which such actual receipt shall fall short of the full amount of the Required Currency so expressed to be
payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. For purposes of the foregoing, “New York Banking Day” means any day except a Saturday, Sunday or a Legal Holiday in

Section 303 Execution, Authentication, Delivery and Dating. 

Securities shall be executed on behalf of the Company by any Officer of the General Partner. The signature of any such Officer on the
Securities may be manual, facsimile, or delivered by any other electronic means. 
 Securities bearing the manual, facsimile, or
electronically-delivered signatures of individuals who were at any time the proper Officers of the General Partner shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the
authentication and delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver Securities, executed by the Company, to the Trustee for authentication and, provided that the Board Resolution and Officer’s Certificate or supplemental indenture
or indentures with respect to such Securities referred to in Section 301 and a Company Order for the authentication and delivery of such Securities have been delivered to the Trustee, the Trustee in accordance with the Company Order and subject
to the provisions hereof and of such Securities shall authenticate and deliver such Securities. In authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee shall
be provided with, and (subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be fully protected in relying upon an Opinion of Counsel and an Officer’s Certificate that contain the statements required by Section 102
and shall also be entitled to receive an Opinion of Counsel stating: 
 (1) if the form or forms of such Securities have been established by
or pursuant to a Board Resolution as permitted by Section 201, that such form or forms have been established in conformity with the provisions of this Indenture; 

(2) if the terms of such Securities have been, or in the case of Securities of a series that are to be authenticated and delivered by the
Trustee on original issue from time to time, will be, established by or pursuant to a Board Resolution as permitted by Section 301, that such terms have been, or in the case of Securities of a series that are to be authenticated and delivered
by the Trustee on original issue from time to time, will be, established in conformity with the provisions of this Indenture, subject, in the case of Securities of a series that are to be authenticated and delivered by the Trustee on original issue
from time to time, to any conditions specified in such Opinion of Counsel; and 
 (3) that (a) such Securities, when authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company and (b) any Guarantees of such Securities,
when such Securities have been so authenticated, delivered and issued, will constitute valid and legally binding obligations of the applicable Guarantor, in each case enforceable in accordance with their terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 

  
 - 18 - 








 If such forms or terms have been so established, the Trustee shall not be required to
authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably
acceptable to the Trustee. 
 Notwithstanding the provisions of Section 301 and of the second preceding paragraph, if all Securities of
a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate or Company Order otherwise required pursuant to such second preceding paragraph at or prior to the authentication of each
Security of such series, if such documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. This paragraph shall not be applicable to Securities of a series that are issued as
part of a reopening pursuant to the last paragraph of Section 301. 
 Each Registered Security shall be dated the date of its
authentication. 
 No Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose, unless there
appears on such Security a certificate of authentication substantially in the form provided for in Section 202 or Section 612 executed by or on behalf of the Trustee or by the Authenticating Agent by the manual signature of one of its
authorized signatories. Such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. 

Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be
entitled to the benefits of this Indenture. 
 Section 304 Temporary Securities. 

Pending the preparation of Definitive Securities, the Company may execute and deliver to the Trustee and, upon Company Order, the Trustee shall
authenticate and deliver, in the manner provided in Section 303, temporary Securities in lieu thereof that are printed, lithographed, typewritten, or otherwise produced, in any authorized denomination, substantially of the tenor of the
Definitive Securities in lieu of which they are issued, in registered form and with such appropriate insertions, omissions, substitutions and other variations as the Officers of the General Partner executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. Such temporary Securities may be in the form of Global Securities. 
 Except
in the case of temporary Global Securities, which shall be exchanged in accordance with the provisions thereof, if temporary Securities are issued, the Company shall cause Definitive Securities to be prepared without unreasonable delay. After the
preparation of Definitive Securities of the same series and containing terms and provisions that are identical to those of any temporary Securities, such temporary Securities shall be exchangeable for such Definitive Securities upon surrender of
such temporary Securities at an Office or Agency for such Securities, without charge to any Holder thereof. Upon surrender for cancellation of any one or more temporary Securities, the Company shall execute and the Trustee shall authenticate and
deliver in exchange therefor a like principal amount of Definitive Securities of authorized denominations of the same series and containing identical terms and provisions. Unless otherwise provided in or pursuant to this Indenture with respect to a
temporary Global Security, until so exchanged the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities of such series. 

Section 305 Registration, Transfer and Exchange. 

With respect to the Registered Securities of each series, if any, the Company shall cause to be kept a register (each such register being
herein sometimes referred to as the “Security Register”) at an Office or Agency for such series in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such series. 

  
 - 19 - 








 Such Office or Agency shall be the “Security Registrar” or
“Registrar” for that series of Securities. Unless otherwise specified in or pursuant to this Indenture or the Securities, the Trustee shall be the initial Security Registrar for each series of Securities. The Company shall have the
right to remove and replace from time to time the Security Registrar for any series of Securities; provided that no such removal or replacement shall be effective until a successor Security Registrar with respect to such series of Securities shall
have been appointed by the Company and shall have accepted such appointment by the Company. If the Trustee shall not be or shall cease to be Security Registrar with respect to a series of Securities, it shall have the right to examine the Security
Register for such series at all reasonable times. There shall be only one Security Register for each series of Securities. 
 A Global
Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary. Notwithstanding the foregoing, except as may be provided pursuant to Section 301, any Global Security or any beneficial interest therein shall be exchangeable for Definitive Securities only
if (i) the Depositary notifies the Company that it is unwilling or unable to continue as Depositary and a successor Depositary is not appointed by the Company within 90 days after the date the Company is so informed in writing, (ii) the
Depositary ceases to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered, and a successor Depositary is not appointed by the Company within 90 days after the date the Company becomes
aware of such cessation, (iii) the Company (subject to the Applicable Procedures) executes and delivers to the Trustee a Company Order to the effect that such Global Security shall be so exchangeable or (iv) an Event of Default has
occurred and is continuing with respect to such Securities and the Depositary requests the issuance of Definitive Securities in exchange for such Global Security. If the holder of a Global Security or the beneficial owners of interests in a Global
Security are entitled to exchange such interests for Definitive Securities as the result of an event specified in clause (i), (ii), (iii) or (iv) of the preceding sentence, the Company shall promptly make available to the Trustee
Definitive Securities in such form and denominations as are required by or pursuant to this Indenture, and of the same series, containing identical terms and in aggregate principal amount equal to the principal amount of such Global Security,
executed by the Company. Such Global Security shall be surrendered from time to time by the U.S. Depositary or such other Depositary as shall be specified in the Company Order with respect thereto, and in accordance with instructions given to the
Trustee and the U.S. Depositary or such other Depositary, as the case may be (which instructions shall be in writing but need not be contained in or accompanied by an Officer’s Certificate or be accompanied by an Opinion of Counsel), as shall
be specified in the Company Order with respect thereto to the Trustee, as the Company’s agent for such purpose, to be exchanged, in whole or in part, for Definitive Securities as described above without charge. The Trustee shall authenticate
and make available for delivery, in exchange for each portion of such surrendered Global Security, a like aggregate principal amount of Definitive Securities of the same series of authorized denominations and of like tenor as the portion of such
Global Security to be exchanged; provided, however, that no such exchanges may occur during a period beginning at the opening of business 15 days before any selection of Securities of the same series to be redeemed and ending on the relevant
Redemption Date. Promptly following any such exchange in part, such Global Security shall be returned by the Trustee to such Depositary or the U.S. Depositary, as the case may be, or such other Depositary or U.S. Depositary referred to above in
accordance with the instructions of the Company referred to above. If a Registered portion of a Global Security is exchanged for Definitive Registered Securities after the close of business at the Office or Agency for such Security where such
exchange occurs on or after (i) any Regular Record Date for such Security and before the opening of business at such Office or Agency on the next Interest Payment Date, or (ii) any Special Record Date for such Security and before the
opening of business at such Office or Agency on the related proposed date for payment of interest or Defaulted Interest, as the case may be, interest shall not be payable on such Interest Payment Date or proposed date for payment, as the case may
be, in respect of such Definitive Registered Security, but shall be payable on such Interest Payment Date or proposed date for payment, as the case may be, only to the Person to whom interest in respect of such portion of such Global Security shall
be payable in accordance with the provisions of this Indenture. 
 The transfer and exchange of beneficial interests in the Global
Securities shall be effected through the Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Transfers and exchanges of beneficial interests in the Global Securities also shall require compliance with
either subparagraph (1) or (2) below, as applicable, as well as one or more of the other following paragraphs, as applicable: 

(1) Beneficial interests in any Global Security may be transferred to Persons who take delivery thereof in the form of a beneficial interest in
the same Global Security. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this subparagraph (1). 

  
 - 20 - 








 (2) In connection with the transfer or exchange of beneficial interests in any Global Security to
Persons who take delivery thereof in the form of a beneficial interest in a different Global Security, the transferor of such beneficial interest must deliver to the Registrar (i) an order from a Participant or an Indirect Participant given to
the Depositary in accordance with the Applicable Procedures directing the Depositary to credit or cause to be credited a beneficial interest in another Global Security in an amount equal to the beneficial interest to be transferred or exchanged and
(ii) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase. Upon satisfaction of all of the requirements for transfer or exchange of beneficial
interests in Global Securities contained in this Indenture and such Securities or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Security(s) pursuant to this paragraph. 

If any Holder of a beneficial interest in a Global Security proposes to exchange such beneficial interest for a Definitive Security or to
transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Security in the event of the occurrence of any of the conditions set forth in the third paragraph of this Section 305, then, upon delivery to
the Registrar of (i) an order from a Participant or an Indirect Participant given to the Depositary in accordance with the Applicable Procedures directing the Depositary to cause to be issued a Definitive Security in an amount equal to the
beneficial interest to be transferred or exchanged and (ii) instructions given by the Depositary to the Registrar containing information regarding the Person in whose name such Definitive Security shall be registered to effect the transfer or
exchange referred to in clause (i), the Trustee shall cause the aggregate principal amount of the applicable Global Security to be reduced accordingly as described below, and the Company shall execute and, upon receipt of a Company Order pursuant to
Section 303, the Trustee shall authenticate and deliver to the Person designated in the instructions, a Definitive Security in the appropriate principal amount. Any Definitive Security issued in exchange for a beneficial interest pursuant to
this paragraph shall be registered in such name or names and in such authorized denomination or denominations as the Holder of such beneficial interest shall instruct the Registrar through instructions from the Depositary and the Participant or
Indirect Participant. The Trustee shall deliver such Definitive Securities to the Persons in whose names such Securities are so registered. 

A Holder of a Definitive Security may exchange such Security for a beneficial interest in a Global Security or transfer such Definitive
Securities to a Person who takes delivery thereof in the form of a beneficial interest in a Global Security at any time. Upon receipt of a request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive Security and
increase or cause to be increased the aggregate principal amount of the applicable Global Security. 
 At the option of the Holder,
Definitive Securities of any series may be exchanged for other Definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Definitive Securities to be exchanged at
an Office or Agency. Whenever any Definitive Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Definitive Securities which the Holder making the exchange is entitled to
receive. 
 Upon request by a Holder of Definitive Securities and such Holder’s compliance with the provisions of this paragraph, the
Registrar shall register the transfer or exchange of Definitive Securities. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Registrar the Definitive Securities duly endorsed or accompanied
by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. A Holder of Definitive Securities may transfer such Securities to a Person who
takes delivery thereof in the form of a Definitive Security. Upon receipt of a request to register such a transfer, the Registrar shall register the Definitive Securities pursuant to the instructions from the Holder thereof. 

At such time as all beneficial interests in a particular Global Security have been exchanged for Definitive Securities or a particular Global
Security has been redeemed, repurchased or cancelled in whole and not in part, each such Global Security shall be returned to or retained and cancelled by the Trustee in accordance with Section 309. At any time prior to such cancellation, if
any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Definitive Securities, the principal amount of Securities
represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depositary at the 

  
 - 21 - 








 
direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial
interest in another Global Security, the principal amount of Securities represented by such other Global Security shall be increased accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Depositary at the
direction of the Trustee to reflect such increase. 
 All Securities issued upon any registration of transfer or exchange of Securities
shall be the valid and legally binding obligations of the Company evidencing the same debt and entitling the Holders thereof to the same benefits under this Indenture as the Securities surrendered upon such registration of transfer or exchange. 

Every Registered Security presented or surrendered for registration of transfer or for exchange or redemption shall (if so required by the
Company or the Security Registrar for such Security) be duly endorsed, signature guaranteed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar for such Security duly executed by the
Holder thereof, signature guaranteed, or his attorney duly authorized in writing. 
 No service charge shall be made for any registration of
transfer or exchange, or redemption of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge and any other expenses (including fees and expenses of the Trustee) that may be imposed in
connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, Section 306, Section 906 and Section 1107 not involving any transfer. 

Except as otherwise provided in or pursuant to this Indenture, the Company shall not be required (i) to issue, register the transfer of
or exchange any Securities during a period beginning at the opening of business 15 days before the day of selection of Securities of like tenor and the same series under Section 1103 for redemption and ending at the close of business on the day
of such selection, (ii) to register the transfer of or exchange any Registered Security so selected for redemption in whole or in part, except in the case of any Security to be redeemed in part, the portion thereof not to be redeemed, or
(iii) to issue, register the transfer of or exchange any Security that, in accordance with its terms, has been surrendered for repayment or purchase at the option of the Holder, except the portion, if any, of such Security not to be so repaid.

 The Registrar shall retain copies of all certificates, notices and other written communications received pursuant to this
Section 305. The Company shall have the right to inspect and make copies of all such certificates, notices or other written communications at any reasonable time upon the giving of reasonable written notice to the Registrar. 

All certifications and certificates required to be submitted to the Registrar pursuant to this Section 305 to effect a registration of
transfer or exchange may (if acceptable to the Registrar) be submitted by facsimile or electronic means, with an original of such document to be sent promptly thereafter. 

Section 306 Mutilated, Destroyed, Lost and Stolen Securities. 

If any mutilated Security is surrendered to the Trustee, subject to the provisions of this Section 306, the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding. 

If there be delivered to the Company and to the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any
Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or to a Responsible Officer that such Security has been
acquired by a “protected purchaser” (as such term is defined in the New York Uniform Commercial Code), the Company shall execute and, upon the Company’s request the Trustee shall authenticate and deliver, in exchange for or in lieu of
any such destroyed, lost or stolen Security, a new Security of the same series containing identical terms and of like principal amount and bearing a number not contemporaneously outstanding. 

  
 - 22 - 








 Notwithstanding the foregoing provisions of this Section 306, in case any mutilated,
destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security. 

Upon the issuance of any new Security under this Section 306, the Company may require the payment of a sum sufficient to cover any tax or
other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith. 

Every new Security issued pursuant to this Section 306 in lieu of any destroyed, lost or stolen Security shall constitute a separate
obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of
such series duly issued hereunder. 
 The provisions of this Section 306, as amended or supplemented pursuant to this Indenture with
respect to particular Securities or generally, shall be exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities. 

Section 307 Payment of Interest and Certain Additional Amounts; Rights to Interest and Certain Additional Amounts Preserved. 

Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional Amounts with respect to, any Registered Security
that shall be payable, and are punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Security (or one or more Predecessor Securities) is registered as of the close of business on the
Regular Record Date for such interest. 
 Unless otherwise provided in or pursuant to this Indenture, any interest on and any Additional
Amounts with respect to, any Registered Security that shall be payable, but shall not be punctually paid or duly provided for, on any Interest Payment Date for such Registered Security (herein called “Defaulted Interest”) shall
forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (1) or
(2) below: 
 (1) The Company may elect to make payment of any Defaulted Interest to the Person in whose name such Registered Security
(or a Predecessor Security thereof) shall be 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 Company shall notify the Trustee in writing of
the amount of Defaulted Interest proposed to be paid on such Registered Security and the date of the proposed payment, and at the same time the Company 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 on or prior to the date of the proposed payment, which money when so deposited shall be held by the Trustee in trust for the benefit
of the Person 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 Company of such Special Record Date and, in the name and at the expense of the
Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to the Holder of such Registered Security (or a Predecessor Security thereof) at his
address as it appears in the Security Register not less than 10 days prior to such Special Record Date. The Trustee may, in its discretion, in the name and at the expense of the Company, cause a similar notice to be published at least once in an
Authorized Newspaper of general circulation in the Borough of Manhattan, The City of New York, but such publication shall not be a condition precedent to the establishment of such Special Record Date. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Person in whose name such Registered Security (or a Predecessor Security thereof) shall be registered at the close of
business on such Special Record Date and shall no longer be payable pursuant to the following clause (2). 

  
 - 23 - 








 (2) The Company may make payment of any Defaulted Interest in any other lawful manner not
inconsistent with the requirements of any securities exchange on which such Security may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to
this clause, such payment shall be deemed practicable by the Trustee. 
 Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series pursuant to the provisions of this Indenture, at the option of the Company, interest on Registered Securities that bear interest may be paid by wire transfer in immediately available funds if the Holder of the
Registered Security has provided to the Company and the Trustee wire instructions at least five Business Days prior to the applicable payment date, or by check mailed to the address of that Holder as it appears on the books of the Securities
Registrar if that Holder has not provided wire instructions; provided that any payment of principal (or premium, if any) in respect of any Security will be made only upon presentation and surrender of such Security at the applicable Office or
Agency. 
 Subject to the foregoing provisions of this Section 307 and Section 305, each Security delivered under this Indenture
upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security. 

In the case of any Registered Security of any series that is convertible, which Registered Security is converted after any Regular Record Date
and on or prior to the immediately succeeding Interest Payment Date (other than any Registered Security with respect to which the Maturity is prior to such Interest Payment Date), interest on such Interest Payment Date shall be payable on such
Interest Payment Date notwithstanding such conversion, and such interest (whether or not punctually paid or duly provided for) shall be paid to the Person in whose name that Registered Security (or one or more predecessor Registered Securities) is
registered at the close of business on such Regular Record Date. Except as otherwise expressly provided in the immediately preceding sentence, in the case of any Registered Security that is converted, interest with respect to which the Stated
Maturity is after the date of conversion of such Registered Security shall not be payable. 
 Section 308 Persons Deemed Owners. 

Prior to due presentment of a Registered Security for registration of transfer, the Company, any Guarantor, the Trustee and any agent of the
Company, any Guarantor, or the Trustee may treat the Person in whose name such Registered Security is registered in the Security Register as the owner of such Registered Security for the purpose of receiving payment of principal of, any premium and
(subject to Section 305 and Section 307) interest on, and any Additional Amounts with respect to, such Registered Security and for all other purposes whatsoever, whether or not any payment with respect to such Registered Security shall be
overdue, and none of the Company, any Guarantor, the Trustee or any agent of the Company, any Guarantor, or the Trustee shall be affected by notice to the contrary. 

No holder of any beneficial interest in any Global Security held on its behalf by a Depositary shall have any rights under this Indenture with
respect to such Global Security, and such Depositary may be treated by the Company, the Trustee and any agent of the Company or the Trustee as the owner of such Global Security for all purposes whatsoever. None of the Company, any Guarantor, the
Trustee, any Paying Agent or the Security 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 309 Cancellation. 

All Securities surrendered for payment, redemption, registration of transfer, exchange or conversion or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee, and any such Securities, as well as Securities surrendered directly to the Trustee for any such purpose, shall be cancelled promptly by the Trustee. The
Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered hereunder that the Company may have acquired in any manner whatsoever, and all Securities so delivered shall be cancelled promptly
by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities cancelled as provided in this Section 309, except as expressly permitted by or pursuant to this Indenture. All cancelled Securities held by the
Trustee shall be disposed of by the Trustee in accordance with its customary procedures. 

  
 - 24 - 








 Section 310 Computation of Interest. 

Except as otherwise provided in or pursuant to this Indenture, or in any Security, interest on the Securities shall be computed on the basis of
a 360-day year of twelve 30-day months and interest on the Securities of each series for any partial period shall be computed on the basis of a 360-day year of twelve 30 day months and the number of days elapsed in any particular month. 

Section 311 CUSIP and ISIN Numbers. 
 The
Company in issuing the Securities may use “CUSIP” and “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use CUSIP and ISIN 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 correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers
printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee of any change in the CUSIP and ISIN numbers. 

ARTICLE FOUR 

SATISFACTION AND DISCHARGE OF INDENTURE 

Section 401 Satisfaction and Discharge. 

Upon the direction of the Company by a Company Order, this Indenture shall cease to be of further effect with respect to any series of
Securities specified in such Company Order and the Trustee, on receipt of a Company Order, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture as to such series, when: 

(1) Either: 
 (a)
all Securities of such series theretofore authenticated and delivered have been delivered to the Trustee for cancellation (other than (i) Securities of such series that have been destroyed, lost or stolen and that have been replaced or paid as
provided in Section 306 and (ii) Securities of such series the payment of money for which has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such
trust, as provided in Section 1003); or 
 (b) all Securities of such series not theretofore delivered to the Trustee
for cancellation: 
 (i) have become due and payable; or 

(ii) will become due and payable at their Stated Maturity within one year; or 

(iii) if redeemable at the option of the Company, are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company; 
 and the
Company, in the case of (i), (ii) or (iii) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose, (x) money in an amount or (y) Government Obligations that through the payment of
interest and principal in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, in the opinion of a nationally recognized Independent Registered Public Accounting Firm expressed in a
written certification thereof delivered to the Trustee, money in the amount, or (z) a combination of (x) and (y) in an amount in the Currency in which such series of Securities are payable, sufficient to pay and discharge the entire
indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, including the principal of, any premium and interest on, and any Additional Amounts with respect to such Securities then determinable, to the date of such
deposit (in the case of Securities which have become due and payable) or to the Maturity thereof, as the case may be; 

  
 - 25 - 








 (2) the Company has paid or caused to be paid all other sums payable hereunder by the Company
with respect to the Outstanding Securities of such series; and 
 (3) the Company has delivered to the Trustee an Officer’s Certificate
and an Opinion of Counsel, each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture as to such series have been complied with. 

If there are Securities of two or more series hereunder, the Trustee shall be required to execute an instrument acknowledging satisfaction and
discharge of this Indenture only if requested to do so with respect to Securities of such series as to which it is Trustee and if the other conditions thereto are met. 

Notwithstanding the satisfaction and discharge of this Indenture with respect to any series of Securities, the obligations of the Company to
the Trustee under Section 607 and to an Authenticating Agent under Section 612, the obligations of the Trustee under Section 403, if money, Government Obligations or a combination thereof shall have been deposited with the Trustee
pursuant to subclause (b) of clause (1) of this Section 401, the obligations of the Company and the Trustee with respect to the Securities of such series under Section 304, Section 305, Section 306, Section 1002
and Section 1003, and the obligations of the Company with respect to the payment of Additional Amounts, if any, with respect to such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable
with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 401(1)(b)), and with respect to any rights to convert or exchange such Securities into Common Units or other securities, cash
or other property, shall survive such satisfaction and discharge. 
 Section 402 Defeasance and Covenant Defeasance. 

(1) Unless pursuant to Section 301, either or both of (i) defeasance of the Securities of a series under clause (2) of this
Section 402 shall not be applicable with respect to the Securities of such series or (ii) covenant defeasance of the Securities of a series under clause (3) of this Section 402 shall not be applicable with respect to the
Securities of such series, then such provisions, together with the other provisions of this Section 402 (with such modifications thereto as may be specified pursuant to Section 301 with respect to any Securities), shall be applicable to
such Securities, and the Company may at its option by Board Resolution, at any time, with respect to such Securities, elect to have Section 402(2) or Section 402(3) be applied to such Outstanding Securities upon compliance with the
conditions set forth below in this Section 402. 
 (2) Upon the Company’s exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company shall be deemed to have been discharged from its obligations with respect to such Outstanding Securities on the date the conditions set forth in clause (5) of
this Section 402 are satisfied (hereinafter, “defeasance”). For this purpose, such defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Outstanding
Securities, which shall thereafter be deemed to be “Outstanding” only for the purposes of the Sections of this Indenture referred to in clauses (i) and (ii) below, and to have satisfied all of its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following, which shall survive until otherwise
terminated or discharged hereunder: (i) the rights of Holders of such Outstanding Securities to receive, solely from the trust fund described in clause (5) of this Section 402 and as more fully set forth in such Section, payments in
respect of the principal of (and premium, if any) and interest, if any, on, and Additional Amounts, if any, with respect to, such Securities when such payments are due, and any rights of such Holder to convert or exchange such Securities into Common
Units or other securities, cash or other property, (ii) the obligations of the Company and the Trustee with respect to such Securities under Section 304, Section 305, Section 306, Section 1002 and Section 1003 and the
obligations of the Company with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 (but only to the extent that the Additional Amounts payable with respect to such Securities exceed the
amount deposited in respect of such Additional Amounts pursuant to Section 402(5)(a) below), and with respect to any rights to convert or exchange such Securities into Common Units or other securities, cash or other property, (iii) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Section 402. The Company may exercise its option under this Section 402(2) notwithstanding the prior exercise of its option under clause (3) of
this Section 402 with respect to such Securities. 

  
 - 26 - 








 (3) Upon the Company’s exercise of the above option applicable to this Section 402(3)
with respect to any Securities of or within a series, (i) the Company shall be released from its obligations to comply with any term, provision or condition under Section 801 and Section 1007 with respect to such Securities (and, to
the extent specified pursuant to Section 301, any other restrictive covenant added for the benefit of such Securities) and (ii) unless otherwise specified pursuant to Section 301, the occurrence of any event specified in
Section 501(8), or with respect to the Guarantors only, the occurrence of any event specified in Section 501(5) or (6), shall not be deemed to be an Event of Default, in each case on and after the date the conditions set forth in clause
(5) of this Section 402 are satisfied (hereinafter, “covenant defeasance”), and such Securities shall thereafter be deemed to be not “Outstanding” for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with any such covenant or Event of Default, but shall continue to be deemed “Outstanding” for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding Securities, the Company and, with respect to Securities of a particular series that are entitled to the benefit of the Guarantee, each Guarantor, may omit to comply with, and shall have no liability in
respect of, any term, condition or limitation set forth in any such covenant or Event of Default, whether directly or indirectly, by reason of any reference elsewhere herein to any covenant or by reason of reference in any such covenant to any other
provision herein or in any other document and such omission to comply shall not constitute a default or an Event of Default under Section 501(4), or Section 501(8) or otherwise, as the case may be, insofar as it relates to Section 801
or Section 1007 and, to the extent specified pursuant to Section 301, any other restrictive covenant added for the benefit of such Security, but, except as specified above, the remainder of this Indenture and such Securities shall be
unaffected thereby; provided that the obligations of the Company with respect to the payment of Additional Amounts, if any, on such Securities as contemplated by Section 1004 shall remain unsatisfied only to the extent that the Additional
Amounts payable with respect to such Securities exceed the amount deposited in respect of such Additional Amounts pursuant to Section 402(5)(a) below; provided, further, that notwithstanding a covenant defeasance with respect to
Section 801 or Section 1007, any Person to whom a sale, assignment, transfer, lease, conveyance or other disposition is made pursuant to Section 801 or Section 1007, shall as a condition to such sale, assignment, transfer, lease,
conveyance or other disposition, assume by an indenture supplemental hereto in form satisfactory to the Trustee, executed by such successor Person and delivered to the Trustee, the obligations of the Company to the Trustee under Section 607,
the second to the last paragraph of Section 402 and the last sentence of Section 1004. 
 (4) If either defeasance or covenant
defeasance occurs with respect to Securities of a particular series that are entitled to the benefit of the Guarantee, the Guarantee will terminate with respect to that series of Securities. 

(5) The following shall be the conditions to the application of clause (2) or (3) of this Section 402 to any Outstanding
Securities of a series: 
 (a) The Company shall irrevocably have deposited or caused to be deposited with the Trustee (or
another trustee satisfying the requirements of Section 608 who shall agree to comply with the provisions of this Section 402 applicable to it) as trust funds in trust for the purpose of making the following payments, specifically pledged
as security for, and dedicated solely to, the benefit of the Holders of such Securities, (1) an amount in Dollars or in such Foreign Currency in which such Securities are then specified as payable at Stated Maturity, or (2) Government
Obligations applicable to such Securities (determined on the basis of the Currency in which such Securities are then specified as payable at Stated Maturity) which through the scheduled payment of principal and interest in respect thereof in
accordance with their terms will provide, not later than one day before the due date of any payment of principal of (and premium, if any) and interest, if any, on such Securities, money in an amount, or (3) a combination thereof, in any case,
in an amount, sufficient, without consideration of any reinvestment of such principal and interest, in the opinion of a nationally recognized Independent Registered Public Accounting Firm expressed in a written certification thereof delivered to the
Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge, (y) the principal of (and premium, if any) and interest or Additional Amounts then determinable, if any, on such
Outstanding Securities at the Maturity of such principal or installment of principal or at the Stated Maturity of such 

  
 - 27 - 








 
interest, provided that the Company shall specify whether such Outstanding Securities are being defeased to Stated Maturity or to the Redemption Date and (z) any mandatory sinking fund
payments or analogous payments applicable to such Outstanding Securities on the day on which such payments are due and payable in accordance with the terms of this Indenture and of such Securities. 

(b) Such defeasance or covenant defeasance shall not result in a breach or violation of, or constitute a default under, this
Indenture or any other material agreement or instrument to which the Company is a party or by which it is bound. 
 (c) No
Event of Default or Default with respect to such Securities shall have occurred and be continuing on the date of such deposit (other than an Event of Default resulting from non-compliance with any covenant from which the Company is released upon the
effectiveness of such defeasance or covenant defeasance, as applicable). 
 (d) In the case of an election under clause
(2) of this Section 402, the Company shall have delivered to the Trustee an Opinion of Counsel stating that: 
 (i)
the Company has received from the Internal Revenue Service a letter ruling, or there has been published by the Internal Revenue Service a Revenue Ruling, or 

(ii) since the date of execution 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 shall confirm that, subject to customary assumptions and exclusions, the
Holders of such Outstanding Securities 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. 
 (e) In the case of an election under clause (3) of this
Section 402, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that, subject to customary assumptions and exclusions, the Holders of such Outstanding Securities 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.

 (f) The Company shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating
that all conditions precedent to the defeasance or covenant defeasance under clause (2) or (3) of this Section 402 (as the case may be) have been complied with. 

(g) If the Securities are to be redeemed prior to their Stated Maturity (other than from mandatory sinking fund payments or
analogous payments), notice of such redemption shall have been duly given pursuant to this Indenture or provision therefor satisfactory to the Trustee shall have been made. 

(h) Notwithstanding any other provisions of this Section 402(5), such defeasance or covenant defeasance shall be effected
in compliance with any additional or substitute terms, conditions or limitations that may be imposed on the Company in connection therewith pursuant to Section 301. 

The Company shall pay and indemnify the Trustee against any tax, fee or other charge, imposed on or assessed against the Government
Obligations deposited pursuant to this Section 402 or the principal or interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of such Outstanding Securities. 

Anything in this Section 402 to the contrary notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon
Company Request any money or Government Obligations (or other property and any proceeds therefrom) held by it as provided in clause (5) of this Section 402 that, in the opinion of a nationally recognized Independent Registered Public
Accounting Firm expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof that would then be required to be deposited to effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 402.

 Section 403 Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 1003, all money and Government Obligations (including the proceeds thereof)
deposited with the Trustee or other qualifying trustee (solely for purposes of this Section 403, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to Section 401 or
Section 402 in respect of any Outstanding Securities of any series shall be held in trust and applied by the Trustee, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying
Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal, premium, if any, interest and Additional Amounts, if any, for whose payment such money has or Government
Obligations have been deposited with or received by the Trustee; but such money and Government Obligations need not be segregated from other funds except to the extent required by law.

 Any
trustee appointed pursuant to Section 402 for the purpose of holding trust funds deposited pursuant to that Section shall be appointed under an agreement in form acceptable to the Trustee and shall provide to the Trustee a certificate of such
trustee, upon which certificate the Trustee shall be entitled to conclusively rely, that all conditions precedent provided for herein to the related defeasance or covenant defeasance have been complied with. In no event shall the Trustee be liable
for any acts or omissions of said trustee. 
 ARTICLE FIVE 

REMEDIES 
 Section 501 Events of
Default.

following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any
administrative or governmental body), unless such event is specifically deleted or modified in or pursuant to any supplemental indenture, Board Resolution or Officer’s Certificate establishing the terms of such series pursuant to this
Indenture:

If an Event of Default specified in clause (5) or (6) of the definition thereof above occurs, the principal (or in the case of
Original Issue Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all Securities, if such Event of Default occurs with respect to the Company, and only those series of Securities that are
entitled to the benefits of a Subsidiary Guarantee by a Subsidiary Guarantor, if such Event of Default occurs with respect to such Subsidiary Guarantor, shall automatically become due and payable without further action or notice, anything contained
in this Indenture or the Securities of each series or established with respect to each series pursuant to Section 301 to the contrary notwithstanding. If upon the occurrence and continuance of an Event of Default specified in any clause (other
than clauses (5) and (6)) of the definition thereof, the Company and the Trustee receive notice in writing that Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of that series have declared the
principal (or in the case of Original Issue 

  
 - 30 - 








 
Discount Securities, such portion of the principal amount as may be specified in the terms of that series) of all Securities of that series to be due and payable immediately, then upon any such
declaration the same shall become and shall be immediately due and payable, anything contained in this Indenture or in the Securities of that series or established with respect to that series to the contrary notwithstanding. 

At any time after a declaration of acceleration or automatic acceleration with respect to the Securities of any series has been made and
before a judgment or decree for payment of the money due has been obtained by the Trustee as hereafter provided in this Article Five, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series, by
written notice to the Company and the Trustee, may rescind and annul the declaration or automatic acceleration and its consequences if: 

(1) the Company, or if any series of Outstanding Securities under this Indenture is entitled to the benefits of a Subsidiary Guarantee by a
Subsidiary Guarantor, any of the Subsidiary Guarantors, has paid or deposited with the Trustee a sum of money sufficient to pay (A) all overdue installments of interest on all Securities of such series and any Additional Amounts payable with
respect thereto, (B) the principal of and any premium on any Securities of the series that have become due otherwise than by the declaration of acceleration or automatic acceleration and interest thereon and any Additional Amounts with respect
thereto at the rate or rates borne by or provided in such Securities, (C) interest upon overdue interest at the rate or rates prescribed therefor in such Securities and (D) all sums paid or advanced by the Trustee hereunder and the
reasonable fees, expenses, disbursements and advances of the Trustee, its agents and counsel; and 
 (2) all Events of Default with respect
to Securities of such series, other than the non-payment of the principal of, any premium and interest on, and any Additional Amounts with respect to, Securities of such series that shall have become due solely by the acceleration, shall have been
cured or waived as provided in Section 513. 
 No such rescission shall affect any subsequent Event of Default or impair any right
consequent thereon. 
 Section 503 Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 

(1) default is made in the payment of any installment of interest on any Security, or any Additional Amounts payable with respect thereto, when
such interest or Additional Amounts shall have become due and payable, and such default continues through the expiration of any cure period specified with respect to such Security; 

(2) default is made in the payment of any principal of or premium, if any, on, or any Additional Amounts payable in respect of any principal of
or premium, if any, on any Security at its Maturity; or 
 (3) default is made in the deposit of any sinking fund payment, when and as due by
the terms of any Security and such default continues through the expiration of any cure period specified with respect to such Security; 
 the Company
shall, upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders of such Securities, the whole amount of money then due and payable with respect to such Securities, with interest upon the overdue principal, any premium and, to
the extent that payment of such interest shall be legally enforceable, upon any overdue installments of interest and Additional Amounts at the rate or rates borne by or provided for in such Securities, and, in addition thereto, such further amount
of money as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee under
Section 607. 
 If the Company fails to pay the money it is required to pay the Trustee pursuant to the preceding paragraph forthwith
upon the demand of the Trustee, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the money so due and unpaid, and may prosecute such proceeding to judgment or final decree,
and may enforce the same against the Company or any other obligor upon such Securities and collect the monies adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such
Securities, wherever situated. 

  
 - 31 - 








 If an Event of Default with respect to the Securities of any series occurs and is continuing, the
Trustee may, and if Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series direct, so long as such Holders shall have provided the Trustee with such indemnity as it shall require and subject to the
provisions of Section 512, the Trustee shall, proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and
enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or such Securities or in aid of the exercise of any power granted herein or therein, or to enforce any other proper remedy. 

Section 504 Trustee May File Proofs of Claim.

judicial proceeding relative to the Company, or if any series of Outstanding Securities under this Indenture is entitled to the benefits of a Subsidiary Guarantee by a Subsidiary Guarantor, any of the Subsidiary Guarantors, upon the Securities or
the property of the Company or, if applicable, any of the Subsidiary Guarantors, or their creditors, the Trustee (irrespective of whether the principal of the Securities 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 on the Company or, if applicable, any of the Subsidiary Guarantors, for the payment of any overdue principal, premium, interest or Additional Amounts) shall be entitled and
empowered, by intervention in such proceeding or otherwise: 
 (1) to file and prove a claim for the whole amount, or such lesser amount as
may be provided for in the Securities of such series, of the principal and any premium, interest and Additional Amounts owing and unpaid in respect of the Securities 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 the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents or counsel) and of the Holders of Securities allowed in such judicial proceeding; and

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by
each Holder of Securities to make such payments to the Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders of Securities, to pay to the Trustee any amount due to it for the reasonable fees, expenses,
disbursements and advances of the Trustee, its agents and counsel and any other amounts due the Trustee under Section 607. 
 Nothing
herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder of a Security any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights
of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder of a Security in any such proceeding.

Trustee May Enforce Claims without Possession of Securities. 
 All rights of action and claims under this Indenture or any of the Securities
may be prosecuted and enforced by the Trustee without the possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee
of an express trust, and any recovery or judgment, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, shall be for the ratable benefit of each and every Holder
of a Security in respect of which such judgment has been recovered.

order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal, or any premium, interest or Additional Amounts, upon presentation of such Securities, and the notation thereon of the payment if
only partially paid and upon surrender thereof if fully paid:

 Section 507 Limitations on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (1) such Holder has previously
given written notice to the Trustee of a continuing Event of Default with respect to the Securities of such series; 
 (2) in the case of an
Event of Default other than an Event of Default specified in clause (5) and (6) of the definition thereof, Holders of not less than 25% in aggregate principal amount of the Outstanding Securities of such series shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder
or Holders have offered to the Trustee indemnity satisfactory to it against the costs, expenses and liabilities to be incurred in compliance with such request; 

(4) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding; and

 (5) no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of not less
than a majority in aggregate principal amount of the Outstanding Securities of such series; 
 it being understood and intended that no one or more of such
Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or any Security to affect, disturb or prejudice the rights of any other such Holders or Holders of Securities of any other series,
or to obtain or to seek to obtain priority or preference over any other Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 

Section 508 Unconditional Right of Holders to Receive Principal and any Premium, Interest and Additional Amounts.

the enforcement of any such payment, and such right shall not be impaired without the consent of such Holder.

 Section 509 Restoration of Rights and Remedies. 

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

Section 510 Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to each and every Holder of a Security is intended to be exclusive of any other right or remedy, and every right and remedy, to the extent
permitted by law, shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall
not, to the extent permitted by law, prevent the concurrent assertion or employment of any other appropriate right or remedy. 
 Section 511 Delay or
Omission Not Waiver. 
 No delay or omission of the Trustee or of any Holder of any Security to exercise any right or remedy accruing upon
any continuing Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Five or by law to the Trustee or to any Holder of a
Security may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by such Holder, as the case may be, subject to the terms and conditions set forth in this Article Five. 

Section 512 Control by Holders of Securities. 

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

(1) such direction shall not be in conflict with any rule of law or with this Indenture or with the Securities of such series and would not
involve the Trustee in personal liability; 
 (2) the Trustee may take any other action deemed proper by the Trustee that is not inconsistent
with such direction; and 
 (3) such direction is not unduly prejudicial to the rights of the other Holders of Securities of such series not
joining in such action. 
 Section 513 Waiver of Past or Existing Defaults. 

The Holders of not less than a majority in principal amount of the Outstanding Securities of any series, on behalf of the Holders of all the
Securities of such series, may waive any past or existing Default or Event of Default hereunder with respect to such series and its consequences, except a continuing default: 

(1) in the payment of the principal of, any premium or interest on, or any Additional Amounts with respect to, any Security of such series; or

 (2) in respect of a covenant or provision hereof that under Article Nine hereof cannot be modified or amended without the consent of the
Holder of each Outstanding Security of such series affected. 

  
 - 34 - 








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

Section 514 Waiver of Stay or Extension Laws. 

The Company covenants that (to the extent that it may lawfully do so) it will not at any time insist upon, or plead, or in any manner
whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture; and the Company expressly waives (to the
extent that it may lawfully do so) all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power
as though no such law had been enacted. 
 Section 515 Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any Security by such Holder’s 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, 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 515 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 10% in principal amount of Outstanding Securities of any 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, if any, on or Additional Amounts,
if any, with respect to any Security on or after the respective Stated Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date, and, in the case of repayment, on or after the date for repayment) or for
the enforcement of the right, if any, to convert or exchange any Security into Common Units or other securities, cash or other property in accordance with its terms.

of a series has occurred (which has not been cured or waived), the Trustee shall exercise the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, with respect to such Securities, as a
prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs. Notwithstanding the foregoing, no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur
any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers. Whether or not therein expressly so provided, every provision of this Indenture relating to the conduct or affecting the

Registrar shall have the same protections as the Trustee set forth hereunder; 
 (10) the Trustee shall not be liable in its individual

that, in connection with any such action taken, suffered or omitted or any such act, the Trustee was negligent, acted in bad faith or engaged in willful misconduct; 

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

with respect to any action taken, suffered or omitted to be taken by it in good faith in accordance with this Indenture or at the direction of the Holders of a majority in aggregate principal amount of the Outstanding Securities relating to the

actual knowledge, the Trustee shall give the Holders of Securities of such series, notice in accordance with Section 313(c) of the Trust Indenture Act of such default hereunder actually known to a Responsible Officer, unless such default shall
have been cured or waived; provided, however, that, except in the case of a default in the payment of the principal of (or premium, if any), or interest, if any, on, or Additional Amounts or any sinking fund or purchase fund installment with respect

shall be under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. 
 Section 607
Compensation and Reimbursement. 
 The Company agrees: 

(1) to pay to the Trustee from time to time such compensation as shall be agreed upon from time to time in writing between the Company and the
Trustee for all services rendered by the Trustee hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); 

(2) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and
advances incurred or made by the Trustee in accordance with any provision of this Indenture arising out of or in connection with the acceptance or administration of the trust or trusts hereunder (including the reasonable fees, expenses and
disbursements of its agents and counsel), except any such expense, disbursement or advance as may be caused by the Trustee’s own negligence or willful misconduct; and 

(3) to fully indemnify each of the Trustee and any predecessor Trustee and its agents, officers, directors and employees for, and to hold them
harmless against, any loss, liability, damage, claim or expense (including reasonable legal fees and expenses), including taxes (other than taxes based on the income of the Trustee), incurred without negligence or willful misconduct on their part,
arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the reasonable costs and expenses of defending themselves against any claim or liability (whether asserted by the Company, a Holder of
Securities, or any other Person) in connection with the exercise or performance of any of their powers or duties hereunder. 
 As security
for the performance of the payment obligations of the Company under this Section 607, the Trustee shall have a lien prior to the Securities of any series 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 or interest on, or any Additional Amounts with respect to, particular Securities. Such lien shall survive the resignation or removal of the Trustee and the satisfaction and discharge of this
Indenture. Without prejudice to any other rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services after a Default or Event of Default specified in Section 501(5) and Section 501(6) hereof
occurs, the expenses and the compensation for the services (including the reasonable fees and expenses of its agents and counsel) are intended to constitute expense of administration under U.S. Code, Title 11 or any other similar foreign, federal or
state law for the relief of debtors.

 Without prejudice to any other rights available to the Trustee under applicable law, to the
extent permitted by law, any compensation or expense incurred by the Trustee after a default specified in or pursuant to Section 501 is intended to constitute an expense of administration under any then applicable bankruptcy or insolvency law.
“Trustee” for purposes of this Section 607 shall include any predecessor Trustee but the negligence or willful misconduct of any Trustee shall not affect the rights of any other Trustee under this Section 607. 

Notwithstanding any other provision of this Indenture to the contrary, in no event shall the Trustee be liable for special, indirect or
consequential damages of any kind whatsoever (including but not limited to lost profits) even if the Trustee had been advised of the likelihood of such loss or damage and regardless of the form of action. 

The provisions of this Section 607 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal
of the Trustee and shall apply with equal force and effect to the Trustee in its capacity as Authenticating Agent, Paying Agent or Security Registrar. 

Section 608 Corporate Trustee Required; Eligibility; Conflicting Interests. 

There shall at all times be a Trustee hereunder that is a Corporation or a national banking association, organized and doing business under the

combined capital and surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000 subject to supervision or examination by federal or state authority. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section 608, it shall resign immediately in the manner and with the effect hereinafter specified in this Article Six. 

If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act, the Trustee shall either eliminate
such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the Trustee shall not be deemed to have a conflicting interest
by virtue of being a trustee under this Indenture with respect to Securities of more than one series.

Six shall become effective until the acceptance of appointment by the successor Trustee pursuant to Section 610. 
 (2) The Trustee may
resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee
within 30 days after the giving of such notice of resignation, the resigning Trustee may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series. 

(3) The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of not less than a majority in
principal amount of the Outstanding Securities of such series, delivered to the Trustee and the Company. If the instrument of acceptance by a successor Trustee required by Section 610 shall not have been delivered to the Trustee within 30 days
after the giving of such notice of removal, the Trustee being removed may petition, at the expense of the Company, any court of competent jurisdiction for the appointment of a successor Trustee with respect to such series. The Trustee for one or
more series of Securities may be removed by the Company, so long as no Default or Event of Default has occurred and is continuing with respect to such series.

 (4) If at any time: 

(a) the Trustee shall fail to comply with the obligations imposed upon it under Section 310(b) of the Trust Indenture Act
with respect to Securities of any series after written request therefor by the Company or any Holder of a Security of such series who has been a bona fide Holder of a Security of such series for at least six months; or 

(b) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by

then, in any such case: 

(i) the Company, by or pursuant to a Company Order, may remove the Trustee with respect to all Securities or the Securities of
such series, or 
 (ii) subject to Section 515, any Holder of a Security who has been a bona fide Holder of a Security
of such series for at least six months may, on behalf of such Holder and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities of such series and the appointment of
a successor Trustee or Trustees. 
 (5) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in
the office of Trustee for any cause, with respect to the Securities of one or more series, the Company, by or pursuant to a Company Order, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of such series (it being
understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall
comply with the applicable requirements of Section 610. If, within one year after such resignation, removal or incapacity, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by
Act of the Holders of not less than a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such
appointment in accordance with the applicable requirements of Section 610, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor
Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders of Securities and accepted appointment in the manner required by Section 610, any Holder of a Security who has been a bona fide
Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such
series. 
 (6) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series

deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in
the retiring Trustee and (3) 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, that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any
other such Trustee and that no Trustee shall be responsible for any notice given to, or received by, or any act or failure to act on the part of any other Trustee hereunder, and, upon the execution and delivery of such supplemental indenture, the
resignation or removal of the retiring Trustee shall become effective to the extent provided therein, such retiring Trustee shall have no further responsibility for the exercise of rights and powers or for the performance of the duties and
obligations vested in the Trustee under this Indenture with respect to the Securities of that or those series to which the appointment of such successor Trustee relates other than as hereinafter expressly set forth, and such successor Trustee,
without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee

trust business of the Trustee by sale or otherwise, shall be the successor of the Trustee hereunder, provided such Corporation or national banking association shall otherwise be qualified and eligible under this Article Six, in each case without the
execution or filing of any paper or any further act on the part of any of the parties hereto. If any Securities shall have been authenticated but not delivered by the Trustee then in office, any successor by merger, conversion or consolidation to
such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

 Section 612 Appointment of Authenticating Agent.

executed on behalf of the Trustee by an Authenticating Agent. 
 Each Authenticating Agent must be acceptable to the Company and, except as

substantially all of the corporate agency or corporate trust business of an Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, provided such Corporation or national banking association shall be otherwise eligible
under this Section 612, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent. 

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and the Company. The Trustee may at any time

prepaid, to all Holders of Registered Securities, if any, of the series with respect to which such Authenticating Agent shall serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent, upon acceptance of
its appointment hereunder, shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless

 Section 902 Supplemental Indentures With Consent of Holders. 

With the consent of the Holders of not less than a majority (or such greater amount as is provided for a particular series of Securities) in
principal amount of the Outstanding Securities of each series affected by such supplemental indenture (including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities of such series), by Act of said
Holders delivered to the Company and the Trustee, the Company and any Guarantor (in each case, when authorized by or pursuant to a Board Resolution) and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the provisions of this Indenture or of modifying in any manner the rights of the Holders of Securities of such series under this Indenture or of the Securities of such series;
provided, however, that no such supplemental indenture, without the consent of the Holder of each Outstanding Security affected thereby, shall: 

(1) change the Stated Maturity of the principal of, or any premium or installment of interest on or any Additional Amounts with respect to, any
Security, or reduce the principal amount thereof or the rate (or modify the calculation of such rate in a manner that reduces such rate) of interest thereon or any Additional Amounts with respect thereto, or any premium payable upon the redemption
thereof or otherwise, or change the obligation of the Company to pay Additional Amounts pursuant to Section 1004, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 502 or the amount thereof provable in bankruptcy pursuant to Section 504, or change the redemption provisions or adversely affect the right of repayment at the option of any Holder
as contemplated by Article Thirteen, or change the Place of Payment for any Security or the Currency in which the principal of, any premium or interest on, or any Additional Amounts with respect to any Security is payable, or impair the right to
institute suit for the enforcement of any such payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date or, in the case of repayment at the option of the Holder, on or after the date for
repayment); or 
 (2) reduce the percentage in principal amount of the Outstanding Securities of any series the consent of the Holders of
which are required for any such supplemental indenture, or the consent of whose Holders is required for any waiver (of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences) provided for in this
Indenture, or reduce the requirements of Section 1504 for quorum or voting; or 
 (3) modify any of the provisions of this
Section 902 or Section 513 or Section 1005, except to increase any percentage set forth in such sections or to provide that certain other provisions of this Indenture cannot be modified or waived without the consent of the Holder of
each Outstanding Security affected thereby; 
 (4) release any Guarantor from any of its obligations under its Guarantee or this Indenture,
other than in accordance with the terms of this Indenture; 
 (5) modify the Guarantee in any manner adverse to the Holders of Securities of
each Outstanding Security covered by such Guarantee; or 
 (6) make any change that adversely affects the right to convert or exchange any
Security into or for Common Units or other securities, cash or other property in accordance with the terms of such Security. 
 A
supplemental indenture that changes or eliminates any covenant or other provision of this Indenture that shall have been included expressly and solely for the benefit of one or more particular series of Securities, or that modifies the rights of the
Holders of Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 

It shall not be necessary for any Act of Holders of Securities under this Section 902 to approve the particular form of any proposed
supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. 

  
 - 48 - 








 Upon the request of the Company and, if applicable, any Guarantor, accompanied by a copy of Board
Resolutions authorizing the execution of any such supplemental indenture, and upon the filing with the Trustee of evidence of the consent of Holders of Securities as aforesaid, the Trustee shall join with the Company and any 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. 
 Section 903 Execution of Supplemental Indentures. 

As a condition to executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article Nine or the
modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying upon, an Officer’s Certificate and Opinion of Counsel stating that the execution of such
supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture that affects the Trustee’s own rights, duties or immunities under this Indenture or
otherwise. 
 Section 904 Revocation of Consents. 

Notwithstanding clause (5) of Section 104, any Holder of a Security or future Holder of the same Security may revoke a consent as to
its Security or portion of a Security. Any revocation of a consent by the Holder of a Security or any such future Holder shall be effective only if the Trustee receives the notice of revocation before the date on which the Trustee receives an
Officer’s Certificate from the Company certifying that the requisite number of consents have been received. If, however, a record date is fixed pursuant to Section 104, then notwithstanding the second preceding sentence, those Persons who
were Holders at such record date (or their duly designated proxies), and only those Persons, shall be entitled to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date. 

Section 905 Effect of Supplemental Indentures. 

A supplemental indenture or waiver becomes effective upon the (A) receipt by the Company or the Trustee of the requisite number of
consents (if required), (B) satisfaction of any conditions to effectiveness as set forth in this Indenture or any such supplemental indenture or waiver and (C) with respect to a supplemental indenture, execution of such supplemental
indenture by the Company, any Guarantors, if applicable, and the Trustee. After a supplemental indenture or waiver becomes effective, it shall bind every Holder, unless such supplemental indenture or waiver makes a change described in any of clauses
(1) through (6) of Section 902, in which case, the supplemental indenture or waiver shall bind a Holder of a Security who is affected thereby only if such Holder has consented to such supplemental indenture or waiver, and every
subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security. Upon the effectiveness of any supplemental indenture under this Article, this Indenture shall be modified in accordance
therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and, except as provided in the preceding sentence, every Holder of Securities theretofore or thereafter authenticated and delivered hereunder shall be
bound thereby. 
 Section 906 Reference in Securities to Supplemental Indentures. 

Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to this Article Nine may, and
shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series so modified as to conform, in the opinion
of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series. 

Section 907 Conformity with Trust Indenture Act. 

Every supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the Trust Indenture Act as then in
effect.

 Section 908 Notice of Supplemental Indenture. 

Promptly after the execution by the Company and, if applicable, the relevant Guarantor, and the Trustee of any supplemental indenture pursuant
to Section 902, the Company shall transmit to the Holders of Outstanding Securities of any series affected thereby a notice setting forth the substance of such supplemental indenture; provided, that any failure to provide, or any defect in any
such notice, shall not impair the validity of any such supplemental indenture. 
 ARTICLE TEN 

COVENANTS 
 Section 1001 Payment of
Principal, any Premium, Interest and Additional Amounts. 
 The Company covenants and agrees for the benefit of the Holders of the Securities
of each series that it will duly and punctually pay the principal of, any premium and interest on and any Additional Amounts with respect to, the Securities of such series in accordance with the terms thereof and this Indenture. 

Section 1002 Maintenance of Office or Agency. 

The Company shall maintain in each Place of Payment for any series of Securities an Office or Agency where Securities of such series may be
presented or surrendered for payment, where Securities of such series may be surrendered for registration of transfer or exchange, where Securities of such series that are convertible or exchangeable may be surrendered for conversion or exchange,
and where notices and demands to or upon the Company in respect of the Securities of such series relating thereto and this Indenture may be served. The Company 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 Company shall fail to maintain any such required Office or Agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. 

The Company may also from time to time designate one or more other Offices or Agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain an Office or
Agency in each Place of Payment for Securities of any series for such purposes. The Company shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other Office or Agency.

 Unless otherwise provided in or pursuant to this Indenture, the Company hereby designates as the Place of Payment for each series of
Securities the Borough of Manhattan, The City of New York, and initially appoints the Corporate Trust Office of U.S. Bank National Association located at 100 Wall Street, New York, New York 10005, as the Office or Agency of the Company in the
Borough of Manhattan, The City of New York for the foregoing purposes. The Company may subsequently appoint a different Office or Agency in the Borough of Manhattan, The City of New York for the Securities of any series. 

Section 1003 Money for Securities Payments to Be Held in Trust. 

If the Company shall at any time act as its own Paying Agent with respect to any series of Securities, it shall, on or before each due date of
the principal of, any premium or interest on or Additional Amounts with respect to any of the Securities of such series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum in the currency or currencies, currency unit
or units or composite currency or currencies in which the Securities of such series are payable (except as otherwise specified pursuant to Section 301 for the Securities of such series) sufficient to pay the principal or any premium, interest
or Additional Amounts so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided, and shall promptly notify the Trustee of its failure so to act. 

  
 - 50 - 








 Whenever the Company shall have one or more Paying Agents for any series of Securities, it shall,
on or prior to each due date of the principal of, any premium or interest on or any Additional Amounts with respect to any Securities of such series, deposit with any Paying Agent a sum (in the currency or currencies, currency unit or units or
composite currency or currencies described in the preceding paragraph) sufficient to pay the principal or any premium, interest or Additional Amounts so becoming due, such sum to be held in trust for the benefit of the Persons entitled thereto, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its failure so to act. 
 The Company shall cause
each Paying Agent for any series of Securities (other than the Trustee) to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section 1003, that such
Paying Agent shall: 
 (1) hold all sums held by it for the payment of the principal of, any premium or interest on or any Additional Amounts
with respect to Securities of such series in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as provided in or pursuant to this Indenture; 

(2) give the Trustee notice of any default by the Company (or any other obligor upon the Securities of such series) in the making of any
payment of principal, any premium or interest on or any Additional Amounts with respect to the Securities of such series; and 
 (3) at any
time during the continuance of any such default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 

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

Except as otherwise provided herein or pursuant hereto, any money deposited with the Trustee or any Paying Agent, or then held by the Company,
in trust for the payment of the principal of, any premium or interest on or any Additional Amounts with respect to any Security of any series and remaining unclaimed for two years after such principal or any such premium or interest or any such
Additional Amounts shall have become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the
Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company either cause to be published once, in an Authorized Newspaper in each Place of Payment for such series, or may cause to be mailed once
to Holders of Registered Securities of such series, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication or mailing nor later than two years after
such principal and any premium or interest or Additional Amounts shall have become due and payable, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 1004 Additional Amounts. 
 If any
Securities of a series provide for the payment of Additional Amounts, the Company shall pay to the Holder of any such Security Additional Amounts as provided in or pursuant to this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or interest on, or in respect of, any Security of any series, such mention shall be deemed to include mention of the payment of Additional Amounts provided by the terms of
such series established hereby or pursuant hereto to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to such terms, and express mention of the payment of Additional Amounts (if
applicable) in any provision hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made. 

  
 - 51 - 








 Except as otherwise provided in or pursuant to this Indenture or the Securities of the applicable
series, if the Securities of a series provide for the payment of Additional Amounts, at least 10 days prior to the first Interest Payment Date with respect to such series of Securities (or if the Securities of such series shall not bear interest
prior to Maturity, the first day on which a payment of principal is made), and at least 10 days prior to each date of payment of principal or interest if there has been any change with respect to the matters set forth in the below-mentioned
Officer’s Certificate, the Company shall furnish to the Trustee and the principal Paying Agent or Paying Agents, if other than the Trustee, an Officer’s Certificate instructing the Trustee and such Paying Agent or Paying Agents whether
such payment of principal of and premium, if any, or interest on the Securities of such series shall be made to Holders of Securities of such series who are United States Aliens (as demonstrated by delivery of appropriate tax forms) without
withholding for or on account of any tax, assessment or other governmental charge described in the Securities of such series. If any such withholding shall be required, then such Officer’s Certificate shall specify by country the amount, if
any, required to be withheld on such payments to such Holders of Securities, and the Company shall pay to the Trustee or such Paying Agent the Additional Amounts required by the terms of such Securities. The Company covenants to indemnify the
Trustee and any Paying Agent for, and to hold them harmless against, any loss, liability or expense reasonably incurred without negligence or bad faith on their part arising out of or in connection with actions taken or omitted by any of them in
reliance on any Officer’s Certificate furnished pursuant to this Section 1004. 
 Section 1005 Waiver of Certain Covenants. 

The Company and the Guarantors may omit in any particular instance to comply with any term, provision or condition specified pursuant to
Section 301 with respect to the Securities of any series if the Company shall have obtained or filed with the Trustee, prior to the time of such failure or omission, evidence (as described in Section 104) of the consent of the Holders of
not less than a majority in aggregate principal amount of the Outstanding Securities of such series, by Act of such Holders, either waiving such compliance in such instance or generally waiving compliance with such term, provision or condition, but
no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective in accordance with Section 905, the obligations of the Company and the Guarantors
and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 
 Section 1006 Company and
Guarantor Statement as to Compliance. 
 (1) If any Securities are Outstanding under this Indenture, the Company and any Guarantors shall
deliver to the Trustee, within 120 days after the end of each fiscal year of the Company or such Guarantors, a written statement (which need not be contained in or accompanied by an Officer’s Certificate) signed by the principal executive
officer, the principal financial officer or the principal accounting officer of the General Partner and of each Guarantor, stating that: 

(a) in the course of the performance of his or her duties as an Officer of the General Partner or a Guarantor, he or she would
normally have knowledge of any default by the Company or such Guarantor in the performance of the covenants contained in this Indenture; and 

(b) to his or her knowledge, the Company or such Guarantor has complied with all the conditions and covenants imposed on it
under this Indenture throughout such year, or, if there has been a noncompliance in the fulfillment of any such condition or covenant, specifying each such noncompliance known to him or her and the nature and status thereof. 

(2) The Trustee shall have no duty to monitor the Company’s or any Guarantor’s compliance with the covenants contained in this
Indenture other than to receive written statements described in Section 1006(1). 
 Section 1007 Existence. 

Subject to Article Eight, the Company and any Guarantor will do or cause to be done all things necessary to preserve and keep in full force and
effect its existence, rights (charter and statutory) and franchises; provided, however, that neither the Company nor such Guarantor shall be required to preserve any such right or franchise if it shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

 ARTICLE ELEVEN 

REDEMPTION OF SECURITIES 

Section 1101 Applicability of Article. 

Redemption of Securities of any series at the option of the Company as permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided herein or pursuant hereto) this Article Eleven. 
 Section 1102 Election
to Redeem; Notice to Trustee. 
 The election of the Company to optionally redeem any Securities shall be evidenced by or pursuant to a Board
Resolution. In case of any redemption at the election of the Company of the Securities of any series, the Company shall, at least 45 days, in the case of any redemption of all of the Securities of such series, and 60 days, in the case of redemption
of fewer than all of the Securities of such series, prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of
Securities of such series to be redeemed. In the case of any redemption of Securities (A) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, or
(B) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities or elsewhere in this Indenture, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance
with such restriction or condition. 
 Section 1103 Selection by Trustee of Securities to be Redeemed. 

If fewer than all of the Securities of any series with the same issue date, interest rate or formula, Stated Maturity and other terms are to be
redeemed, the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee from the Outstanding Securities of such series not previously called for redemption, on a pro rata basis or by lot
(whichever is consistent with the Trustee’s customary practice); provided, that if Securities of any series are represented by one or more Global Securities, interests in such Global Securities shall be selected for redemption by the Depositary
in accordance with its customary procedures; provided, further, that no such partial redemption shall reduce the portion of the principal amount of a Registered Security of such series not redeemed to less than the minimum denomination for a
Security of such series established herein or pursuant hereto. 
 The Trustee shall promptly notify the Company and the Security Registrar
(if other than itself) in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. 

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall
relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal of such Securities that has been or is to be redeemed. 

Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if any Security selected for partial redemption
is converted into or exchanged for Common Units or other securities, cash or other property in part before termination of the conversion or exchange right with respect to the portion of the Security so selected, the converted portion of such
Security shall be deemed (so far as may be) to be the portion selected for redemption. Securities that have been converted or exchanged during a selection of Securities to be redeemed shall be treated by the Trustee as Outstanding for the purpose of
such selection. 
 Section 1104 Notice of Redemption. 

Notice of redemption shall be given in the manner provided in Section 106 not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to the Holders of Securities to be redeemed. Failure to give notice by mailing in the manner herein provided to the Holder of any Registered Securities designated for
redemption as a whole or in part, or any defect in the notice to any such Holder, shall not affect the validity of the proceedings for the redemption of any other Securities or portion thereof. 

  
 - 53 - 








 Any notice that is mailed to the Holder of any Registered Securities in the manner herein
provided shall be conclusively presumed to have been duly given, whether or not such Holder receives the notice. 
 All notices of
redemption shall state: 
 (1) the Redemption Date; 

(2) the Redemption Price or if not then ascertainable, the manner of calculation thereof; 

(3) if less than all Outstanding Securities of any series are to be redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed; 
 (4) in case any Security is to be redeemed in part only, the
notice that relates to such Security shall state that on and after the Redemption Date, upon surrender of such Security, the Holder of such Security will receive, without charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed; 
 (5) that, on the Redemption Date, the Redemption Price shall become due and payable upon
each such Security or portion thereof to be redeemed, and, if applicable, that interest thereon shall cease to accrue on and after said date, subject to such conditions as may be specified pursuant to Section 301 with respect to such Security;

 (6) the place or places where such Securities are to be surrendered for payment of the Redemption Price and any accrued interest and
Additional Amounts pertaining thereto; 
 (7) that the redemption is for a sinking fund, if such is the case; 

(8) in the case of Securities of any series that are convertible or exchangeable into Common Units or other securities, cash or other property,
the conversion or exchange price or rate, the date or dates on which the right to convert or exchange the principal of the Securities of such series to be redeemed will commence or terminate and the place or places where such Securities may be
surrendered for conversion or exchange; and 
 (9) the CUSIP number (or any other numbers used by a Depositary to identify such Securities).

 Notice of redemption of Securities to be redeemed at the election of the Company shall be given by the Company or, upon Company Request,
by the Trustee in the name and at the expense of the Company. 
 Section 1105 Deposit of Redemption Price. 

At or prior to 10:00 a.m., New York City time, on any Redemption Date, the Company shall deposit, with respect to the Securities of any series
called for redemption pursuant to Section 1104, with the Trustee or with a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money in the applicable
Currency sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date, unless otherwise specified pursuant to Section 301 or in the Securities of such series) any accrued interest on and
Additional Amounts with respect to such accrued interest, all such Securities or portions thereof which are to be redeemed on that date. 

Section 1106 Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid and all conditions specified pursuant to Section 301 having been satisfied, the
Securities so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest)
such Securities shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with any accrued interest and Additional
Amounts to the Redemption Date; provided, however, that, except as otherwise specified in or pursuant to this Indenture or the Registered Securities of such series, installments of interest on Registered Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor Securities, registered as such at the close of business on the Regular Record Dates therefor according to their terms and the provisions of
Section 307. 

  
 - 54 - 








 Unless otherwise specified in or pursuant to this Indenture or the Securities of any series, if
any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal and any premium, until paid, shall bear interest from the Redemption Date at the rate prescribed therefor in the Security. 

Section 1107 Securities Redeemed in Part. 

Any Registered Security that is to be redeemed only in part shall be surrendered at any Office or Agency for such Security (with, if the
Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing) and the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Registered Security or Securities of the same series, containing identical terms and provisions, 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 amount of the Security so surrendered. Subject to Section 203, if a Global Security is so surrendered, the Company shall
execute, and the Trustee shall authenticate and deliver to or on behalf of the U.S. Depositary or other Depositary for such Global Security as shall be specified in the Company Order with respect thereto to the Trustee, 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. 

Section 1108 Repurchases on the Open Market. 

The Company or any Affiliate of the Company may at any time or from time to time repurchase any of the Securities in the open market or
otherwise. Such Securities may, at the option of the Company or the relevant Affiliate of the Company, be held, resold or surrendered to the Trustee for cancellation.

pursuant to the terms of such Securities (1) deliver Outstanding Securities of such series (other than any of such Securities previously called for redemption or any of such Securities in respect of which cash shall have been released to the
Company) and (2) apply as a credit Securities of such series that have been redeemed either at the election of the Company pursuant to the terms of such series of Securities or through the application of permitted optional sinking fund payments
pursuant to the terms of such Securities, provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. If as a result of the delivery or credit of Securities of any series in lieu of cash payments pursuant to this
Section 1202, the principal amount of 

  
 - 55 - 








 
Securities of such series to be redeemed in order to satisfy the remaining sinking fund payment shall be less than $100,000, the Trustee need not call Securities of such series for redemption,
except upon Company Request, and such cash payment shall be held by the Trustee or a Paying Agent and applied to the next succeeding sinking fund payment, provided, however, that the Trustee or such Paying Agent shall at the request of the Company
from time to time pay over and deliver to the Company any cash payment so being held by the Trustee or such Paying Agent upon delivery by the Company to the Trustee of Securities of that series purchased by the Company having an unpaid principal
amount equal to the cash payment requested to be released to the Company. 
 Section 1203 Redemption of Securities for Sinking Fund. 

Not less than 60 days prior to each sinking fund payment date for any series of Securities, the Company shall deliver to the Trustee an
Officer’s Certificate specifying the amount of the next ensuing mandatory sinking fund payment for that series pursuant to the terms of that series, the portion thereof, if any, that is to be satisfied by payment of cash and the portion
thereof, if any, that is to be satisfied by delivering and crediting of Securities of that series pursuant to Section 1202, and the basis for such credit and the optional amount, if any, to be added in cash to the next ensuing mandatory sinking
fund payment, and will also deliver to the Trustee any Securities to be so credited and not theretofore delivered. If such Officer’s Certificate shall specify an optional amount to be added in cash to the next ensuing mandatory sinking fund
payment, the Company shall thereupon be obligated to pay the amount therein specified. Not less than 60 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the
manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 1104. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Section 1106 and Section 1107. 
 ARTICLE THIRTEEN 

REPAYMENT AT THE OPTION OF HOLDERS 

Section 1301 Applicability of Article. 

Securities of any series that are repayable at the option of the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal amount of Securities pursuant to such option of the Holder to require repayment of Securities before their Stated Maturity, for purposes of Section 309, shall not
operate as a payment, redemption or satisfaction of the indebtedness represented by such Securities unless and until the Company, at its option, shall deliver or surrender the same to the Trustee with a directive that such Securities be cancelled.
Notwithstanding anything to the contrary contained in this Section 1301, in connection with any repayment of Securities, the Company may arrange for the purchase of any Securities by an agreement with one or more investment bankers or other
purchasers to purchase such Securities by paying to the Holders of such Securities on or before the close of business on the repayment date an amount not less than the repayment price payable by the Company on repayment of such Securities, and the
obligation of the Company to pay the repayment price of such Securities shall be satisfied and discharged to the extent such payment is so paid by such purchasers. 

ARTICLE FOURTEEN 

SECURITIES IN FOREIGN CURRENCIES 

Section 1401 Applicability of Article. 

Whenever this Indenture provides for (1) any action by, or the determination of any of the rights of, Holders of Securities of any series
in which not all of such Securities are denominated in the same Currency, or (2) any distribution to Holders of Securities, in the absence of any provision to the contrary pursuant to this Indenture or the Securities of any particular series,
any amount in respect of any Security denominated in a Foreign Currency shall be treated for any such action or distribution as that amount of Dollars that could be obtained for such amount on such reasonable basis of exchange and as of the record
date with respect to Registered Securities of such series (if any) for such action, determination of rights or distribution (or, if there shall be no applicable record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written notice to the Trustee or, in the absence of such written notice, as the Trustee may determine.

The Trustee shall be protected in basing any such exchange on the noon dollar buying rate in The City of New York for cable transfers of such Foreign Currency published by the Federal Reserve
Bank of New York on the Business Day immediately preceding the date of such determination or on any other basis that the Trustee determines in good faith to be customary.

ARTICLE SIXTEEN 

GUARANTEE 
 Section 1601 Guarantee
Only of Securities of Any Series Designated. 
 (1) Notwithstanding any provision of this Article Sixteen to the contrary, the provisions of
this Article Sixteen shall be applicable only to, and inure solely to the benefit of, the Securities of any series so designated, pursuant to Section 301, as entitled to the benefits of the Guarantee of each of the Guarantors. 

Section 1602 Subordinated or Conditional Guarantee 

(1) To the extent set forth in a supplement to this Indenture or any Securities, the terms of any Guarantee of Securities of any series may
provide that such Guarantee is conditional and/or subject to subordination (a “Conditional Guarantee”) and may include terms that provide, among other things, that such Conditional Guarantee is a Guarantee of collection, and not of
payment, of the Company’s obligations under such Securities and this Indenture and that the duration of such Conditional Guarantee is limited or that such Conditional Guarantee is subject to automatic termination, release or discharge. 

Section 1603 Subsidiary Guarantee 
 (1) For
value received, each Subsidiary Guarantor party to a supplement to this Indenture or any Securities and identified as the same hereby fully, unconditionally and absolutely guarantees (the “Subsidiary 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 Securities and all other amounts due and payable under this Indenture and the Securities by the Company (including, without limitation, all
costs and expenses (including reasonable legal fees and disbursements) incurred by the Trustee or the Holders in connection with the enforcement of this Indenture and the Subsidiary Guarantee), 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, and when and as such other amounts shall become due and payable, according to the terms of the Securities and
this Indenture, subject to the limitations set forth in Section 1605. 
 (2) Failing payment when due of any amount guaranteed pursuant
to the Subsidiary Guarantee, for whatever reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately to the Trustee, without set off or counterclaim or other reduction whatsoever (whether for taxes,
withholding or otherwise). The Subsidiary 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 Subsidiary Guarantee, and is intended to be a guarantee of payment, and not of collection. Each of the Subsidiary Guarantors hereby agrees that its obligations
hereunder shall be full, unconditional and absolute, irrespective of the validity, 

  
 - 59 - 








 
regularity or enforceability of the Securities, the Subsidiary Guarantee (including the Subsidiary 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 Securities with respect to any provisions hereof or thereof, the recovery of any judgment against the Company 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 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 on the terms and
conditions set forth in this Indenture, directly against such Subsidiary Guarantor to enforce the Subsidiary Guarantee without first proceeding against the Company or any other Subsidiary Guarantor. 

(3) The obligations of each of the Subsidiary Guarantors under this Article Sixteen 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 the Company or any of the Subsidiary Guarantors contained in the Securities or this Indenture, (b) any impairment, modification, release or limitation of the liability of the Company, any of 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, insolvency, reorganization or other similar law, or
other statute or from the decision of any court, (c) the assertion or exercise by the Company, any of the Subsidiary Guarantors or the Trustee of any rights or remedies under the 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 Securities, including all or any part of the rights of the Company or any of the Subsidiary Guarantors under this
Indenture, (e) the extension of the time for payment by the Company or any of 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 Securities or this Indenture
or of the time for performance by the Company or any of 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 the Company or any of 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,
the Company or any of the Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the Securities, the Subsidiary Guarantee or this Indenture in any such proceeding, (h) the release or discharge of the Company or any of
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 Securities, the Subsidiary Guarantee or this
Indenture or (j) any other circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the Subsidiary Guarantee) that might otherwise constitute a legal or equitable discharge of a surety or guarantor. 

(4) 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 the Company or any of the Subsidiary Guarantors, and all demands whatsoever, (b) acknowledges that any agreement, instrument or document evidencing the Subsidiary 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 Subsidiary Guarantee without notice to it and (c) covenants that the Subsidiary Guarantee will not be discharged
except by complete performance of the Subsidiary 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 the Company or any of the Subsidiary Guarantors, the Subsidiary 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 Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 

(5) Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and the Trustee against the Company 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 Securities and the Subsidiary Guarantee shall have been paid in full or discharged.

 Section 1604 Execution and Delivery of Guarantee. 

To further evidence a Guarantee set forth in this Article Sixteen, each of the Guarantors hereby agrees that a notation relating to such
Guarantee (substantially in the form attached hereto as Annex A in the case of a Subsidiary Guarantee), shall be endorsed on each Security entitled to the benefits of the Guarantee authenticated and delivered by the Trustee and executed by either
manual, facsimile or electronic signature of an officer of such Guarantor, or in the case of a Guarantor that is a limited partnership, an officer of the general partner of such Guarantor. Each of the Guarantors hereby agrees that the Guarantee set
forth in this Article Sixteen shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to the Guarantee. If any officer of any Guarantor, or in the case of a Guarantor that is a limited
partnership, any officer of the general partner of the Guarantor, whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, the Guarantee of such
Security shall be valid nevertheless. The delivery of any 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 Guarantors. 

The Trustee hereby accepts the trusts in this Indenture upon the terms and conditions herein set forth. 

Section 1605 Limitation on Guarantors’ Liability. 

Each Guarantor and by its acceptance hereof each Holder of a Security entitled to the benefits of the Guarantee hereby confirm that it is the
intention of all such parties that the guarantee by such Guarantor pursuant to the Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Federal or state law. To effectuate the foregoing intention, the Holders of a
Security entitled to the benefits of the Guarantee and the Guarantors hereby irrevocably agree that the obligations of each 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 Guarantor and to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under the Guarantee, not result in the obligations of such Guarantor under
the Guarantee constituting a fraudulent conveyance or fraudulent transfer under Federal or state law. 
 Section 1606 Release of Guarantors from
Guarantee. 
 (1) Notwithstanding any other provisions of this Indenture, the Guarantee of any Guarantor may be released upon the terms and
subject to the conditions set forth in Section 402 and in this Section 1606 or, in any event, in accordance with the terms of such Guarantee or the supplement to this Indenture pursuant to which such Guarantee was issued. Provided that no
Default shall have occurred and shall be continuing under this Indenture, the Guarantee incurred by a Guarantor pursuant to this Article Sixteen shall be unconditionally released and discharged (i) following delivery of an Officer’s
Certificate to the Trustee to the effect that such release or discharge has occurred pursuant to the terms and conditions of any series of Securities covered by such Guarantee, or (ii) automatically upon (A) any sale, exchange or transfer,
whether by way of merger or otherwise, to any Person that is not an Affiliate of the Company, of all of the Company’s direct or indirect limited partnership or other equity interests in such Guarantor (provided such sale, exchange or transfer
is not prohibited by this Indenture) or (B) the merger of such Guarantor into the Company or any other Guarantor or the liquidation and dissolution of such Guarantor (to the extent such liquidation or dissolution is expressly permitted (without
regard to Section 101(12)) by this Indenture or the applicable Securities). 
 (2) The Trustee shall deliver an appropriate instrument
evidencing any release of a Guarantor from the Guarantee upon receipt of a written request of the Company accompanied by an Officers’ Certificate and an Opinion of Counsel to the effect that the Guarantor is entitled to such release in
accordance with the provisions of this Indenture. Any Guarantor not so released shall remain obligated under such Guarantee as provided in this Indenture, subject to the limitations of Section 1605. 

  
 - 61 - 








 Section 1607 Guarantor Contribution. 

In order to provide for just and equitable contribution among 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 Subsidiary 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 Company’s obligations with respect to
the Securities or any other Subsidiary Guarantor’s obligations with respect to the Subsidiary Guarantee.
