 Section 2.04. Execution of Debt Securities. The Debt Securities
shall be signed on behalf of the Partnership by one authorized Officer of the General Partner. Such signatures upon the Debt Securities may be the manual or facsimile signatures of the present or any future such authorized Officer and may be
imprinted or otherwise reproduced on the Debt Securities. No seal of any party shall be required in connection with the execution or delivery of any Debt Securities. 
 Only such Debt Securities as shall bear thereon a certificate of authentication substantially in the form hereinbefore recited, signed manually by the Trustee, shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose. Such certificate by the Trustee upon any Debt Security executed by the Partnership shall be conclusive evidence that the Debt Security so authenticated has been duly authenticated and delivered hereunder.

 In case any Officer who shall have signed any of the Debt Securities shall cease to hold that office before the Debt Securities so signed
shall have been authenticated and delivered by the Trustee, or disposed of by the Partnership, such Debt Securities nevertheless may be authenticated and delivered or disposed of as though the Person who signed such Debt Securities had not ceased to
hold such office; and any Debt Security may be signed on behalf of the Partnership by such Persons as, at the actual date of the execution of such Debt Security, shall be 

  

 11 

 
the proper Officers of the General Partner, although at the date of such Debt Security or of the execution of this Indenture any such Person did not hold
such office. 
 Section 2.05. Authentication and Delivery of Debt Securities. At any time and from time to time after the
execution and delivery of this Indenture, the Partnership may deliver Debt Securities of any series executed by the Partnership to the Trustee for authentication, and the Trustee shall thereupon authenticate and deliver said Debt Securities upon a
Partnership Order. In authenticating such Debt Securities, and accepting the additional responsibilities under this Indenture in relation to such Debt Securities, the Trustee shall be entitled to receive, and (subject to Section 7.01) shall be
fully protected in relying upon: 
 (a) a copy of any resolution or resolutions of the Board of Directors, certified by the Secretary or
Assistant Secretary of the General Partner, authorizing the terms of issuance of any series of Debt Securities; 
 (b) an executed
supplemental indenture, if any; 
 (c) an Officers’ Certificate; and 
 (d) an Opinion of Counsel prepared in accordance with Section 15.05 which shall also state: 
 (i) that the form of such Debt Securities has been established by or pursuant to a resolution of the Board of Directors or by a
supplemental indenture as permitted by Section 2.01 in conformity with the provisions of this Indenture; 
 (ii) that the
terms of such Debt Securities have been established by or pursuant to a resolution of the Board of Directors or by a supplemental indenture as permitted by Section 2.03 in conformity with the provisions of this Indenture; 
 (iii) that such Debt Securities, when authenticated and delivered by the Trustee and issued by the Partnership in the manner and subject
to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Partnership, enforceable in accordance with their terms except as the enforceability thereof may be limited by bankruptcy,
insolvency or similar laws affecting the enforcement of creditors’ rights generally and rights of acceleration and the availability of equitable remedies may be limited by equitable principles of general applicability; and 
 (iv) that authentication and delivery of such Debt Securities and the execution and delivery of any supplemental indenture will not
violate the terms of this Indenture. 
 The Trustee shall have the right to decline to authenticate and deliver any Debt Securities under
this Section 2.05 if the Trustee, being advised by counsel, determines that such action may not lawfully be taken or if the Trustee in good faith by its board of directors or trustees, executive committee or a trust committee of directors,
trustees or vice presidents (or any combination thereof) shall determine that such action would expose the Trustee to personal liability to existing Holders. 
  

 12 

 The Trustee may appoint an authenticating agent reasonably acceptable to the Partnership to authenticate
Debt Securities of any series. Unless limited by the terms of such appointment, an authenticating agent may authenticate Debt Securities whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes
authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent for service of notices and demands. 
 Unless otherwise provided in the form of Debt Security for any series, each Debt Security shall be dated the date of its authentication. 
 Section 2.06. Denomination of Debt Securities. Unless otherwise provided in the form of Debt Security for any series, the Debt Securities of each series shall be issuable only as fully registered Debt
Securities in such Dollar denominations as shall be specified or contemplated by Section 2.03. In the absence of any such specification with respect to the Debt Securities of any series, the Debt Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof. 
 Section 2.07. Registration of Transfer and Exchange. 
 (a) The Partnership shall keep or cause to be kept a register for each series of Debt Securities issued hereunder (hereinafter collectively referred to
as the “Debt Security Register”), in which, subject to such reasonable regulations as it may prescribe, the Partnership shall provide for the registration of all Debt Securities and the transfer of Debt Securities as in this
Article II provided. At all reasonable times the Debt Security Register shall be open for inspection by the Trustee. Subject to Section 2.15, upon due presentment for registration of transfer of any Debt Security at any office or agency to
be maintained by the Partnership in accordance with the provisions of Section 4.02, the Partnership shall execute and the Trustee shall authenticate and deliver in the name of the transferee or transferees a new Debt Security or Debt Securities
of authorized denominations for a like aggregate principal amount. In no event may Debt Securities be issued as, or exchanged for, bearer securities. 
 Unless and until otherwise determined by the Partnership by a Partnership Order, the Debt Security Register shall be kept at the principal corporate trust office of the Trustee and, for this purpose, the Trustee shall
be designated “Registrar.” 
 Debt Securities of any series (other than a Global Security, except as set forth below) may be
exchanged for a like aggregate principal amount of Debt Securities of the same series of other authorized denominations. Subject to Section 2.15, Debt Securities to be exchanged shall be surrendered at the office or agency to be maintained by
the Partnership as provided in Section 4.02, and the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor the Debt Security or Debt Securities which the Holder making the exchange shall be entitled to
receive. 
 (b) All Debt Securities presented or surrendered for registration of transfer, exchange or payment shall (if so required by the
Partnership, the Trustee or the Registrar) be duly endorsed or accompanied by a written instrument or instruments of transfer, in form satisfactory to the 

  

 13 

 
Partnership, the Trustee and the Registrar, duly executed by the Holder or his attorney duly authorized in writing. 
 All Debt Securities issued in exchange for or upon transfer of Debt Securities shall be the valid obligations of the Partnership, evidencing the same
debt, and entitled to the same benefits under this Indenture as the Debt Securities surrendered for such exchange or transfer. 
 No service
charge shall be made for any exchange or registration of transfer of Debt Securities (except as provided by Section 2.09), but the Partnership may require payment of a sum sufficient to cover any tax, fee, assessment or other governmental
charge that may be imposed in relation thereto, other than those expressly provided in this Indenture to be made at the Partnership’s own expense or without expense or charge to the Holders. 
 The Partnership shall not be required (i) to issue, register the transfer of or exchange any Debt Securities for a period of 15 days preceding any
mailing of notice of redemption of Debt Securities of such series or (ii) to register the transfer of or exchange any Debt Securities selected, called or being called for redemption. 
 Prior to the due presentation for registration of transfer of any Debt Security, the Partnership, each Guarantor (if any), the Trustee, any Paying Agent
or any Registrar may deem and treat the Person in whose name a Debt Security is registered as the absolute owner of such Debt Security for the purpose of receiving payment of or on account of the principal of, and premium, if any, and (subject to
Section 2.12) interest on, such Debt Security and for all other purposes whatsoever, whether or not such Debt Security is overdue, and none of the Partnership, any Guarantor, the Trustee, any Paying Agent or any Registrar shall be affected by
notice to the contrary. 
 None of the Partnership, any Guarantor, the Trustee, any agent of the Trustee, any Paying Agent or any Registrar
will have any responsibility or liability for any aspect of the records relating to, or payments made on account of, beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests. 
 Section 2.08. Temporary Debt Securities. Pending the preparation of definitive Debt Securities
of any series, the Partnership may execute and the Trustee shall authenticate and deliver temporary Debt Securities of any authorized denomination, and substantially in the form of the definitive Debt Securities in lieu of which they are issued, in
registered form with such omissions, insertions and variations as may be appropriate for temporary Debt Securities, all as may be determined by the Partnership with the concurrence of the Trustee. Temporary Debt Securities may contain such reference
to any provisions of this Indenture as may be appropriate. Every temporary Debt Security shall be executed by the Partnership and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with like effect, as
the definitive Debt Securities. 
 If temporary Debt Securities of any series are issued, the Partnership will cause definitive Debt
Securities of such series to be prepared without unreasonable delay. After the preparation of definitive Debt Securities of such series, the temporary Debt Securities of such series shall be 

  

 14 

 
exchangeable for definitive Debt Securities of such series upon surrender of the temporary Debt Securities of such series at the office or agency of the
Partnership at a Place of Payment for such series, without charge to the Holder thereof, except as provided in Section 2.07 in connection with a transfer. Upon surrender for cancellation of any one or more temporary Debt Securities of any
series, the Partnership shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Debt Securities of the same series of authorized denominations and of like tenor. Until so exchanged,
temporary Debt Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive Debt Securities of such series. 
 Upon any exchange of a portion of a temporary Global Security for a definitive Global Security or for the individual Debt Securities represented thereby pursuant to Section 2.07 or this Section 2.08, the
temporary Global Security shall be endorsed by the Trustee to reflect the reduction of the principal amount evidenced thereby, whereupon the principal amount of such temporary Global Security shall be reduced for all purposes by the amount to be
exchanged and endorsed. 
 Section 2.09. Mutilated, Destroyed, Lost or Stolen Debt Securities. If (a) any mutilated Debt
Security is surrendered to the Trustee at its corporate trust office or (b) the Partnership and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Debt Security, and there is delivered to the Partnership
and the Trustee such security or indemnity as may be required by them to save each of them and any Paying Agent harmless, and neither the Partnership nor the Trustee receives notice that such Debt Security has been acquired by a bona fide purchaser,
then the Partnership shall execute and, upon a Partnership Order, the Trustee shall authenticate and deliver, in exchange for or in lieu of any such mutilated, destroyed, lost or stolen Debt Security, a new Debt Security of the same series of like
tenor, form, terms and principal amount, bearing a number not contemporaneously Outstanding. Upon the issuance of any substituted Debt Security, the Partnership may require the payment of a sum sufficient to cover any tax, fee, assessment or other
governmental charge that may be imposed in relation thereto and any other expenses connected therewith. In case any Debt Security which has matured or is about to mature or which has been called for redemption shall become mutilated or be destroyed,
lost or stolen, the Partnership may, instead of issuing a substituted Debt Security, pay or authorize the payment of the same (without surrender thereof except in the case of a mutilated Debt Security) if the applicant for such payment shall furnish
the Partnership and the Trustee with such security or indemnity as either may require to save it harmless from all risk, however remote, and, in case of destruction, loss or theft, evidence to the satisfaction of the Partnership and the Trustee of
the destruction, loss or theft of such Debt Security and of the ownership thereof. 
 Every substituted Debt Security of any series issued
pursuant to the provisions of this Section 2.09 by virtue of the fact that any Debt Security is destroyed, lost or stolen shall constitute an original contractual obligation of the Partnership, whether or not the destroyed, lost or stolen Debt
Security shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Debt Securities of that series duly issued hereunder. All Debt Securities shall be held and owned
upon the express condition that the foregoing provisions are exclusive with respect to the replacement or payment of mutilated, destroyed, lost or stolen Debt Securities, and shall preclude any and all other rights or remedies, 

  

 15 

 
notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or payment of negotiable instruments or
other securities without their surrender. 
 Section 2.10. Cancellation of Surrendered Debt Securities. All Debt Securities
surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to the Partnership or any Paying Agent or a Registrar, be delivered to the Trustee for cancellation by it, or if surrendered to the Trustee, shall be
canceled by it, and no Debt Securities shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All canceled Debt Securities held by the Trustee shall be destroyed (subject to the record retention
requirements of the Exchange Act) and certification of their destruction delivered to the Partnership, unless otherwise directed. On request of the Partnership, the Trustee shall deliver to the Partnership canceled Debt Securities held by the
Trustee. If the Partnership shall acquire any of the Debt Securities, however, such acquisition shall not operate as a redemption or satisfaction of the Debt represented thereby unless and until the same are delivered or surrendered to the Trustee
for cancellation. The Partnership may not issue new Debt Securities to replace Debt Securities it has redeemed, paid or delivered to the Trustee for cancellation. 
 Section 2.11. Provisions of the Indenture and Debt Securities for the Sole Benefit of the Parties and the Holders. Nothing in this Indenture or in the Debt Securities, expressed or implied, shall give or
be construed to give to any Person, other than the parties hereto, the Holders or any Registrar or Paying Agent, any legal or equitable right, remedy or claim under or in respect of this Indenture, or under any covenant, condition or provision
herein contained; all its covenants, conditions and provisions being for the sole benefit of the parties hereto, the Holders and any Registrar and Paying Agents. 
 Section 2.12. Payment of Interest; Interest Rights Preserved. 
 (a) Interest on any Debt
Security that is payable and is punctually paid or duly provided for on any interest payment date shall be paid to the Person in whose name such Debt Security is registered at the close of business on the regular record date for such interest
notwithstanding the cancellation of such Debt Security upon any transfer or exchange subsequent to the regular record date. Payment of interest on Debt Securities shall be made at the corporate trust office of the Trustee (except as otherwise
specified pursuant to Section 2.03), or at the option of the Partnership, by check mailed to the address of the Person entitled thereto as such address shall appear in the Debt Security Register or, if provided pursuant to Section 2.03 and
in accordance with arrangements satisfactory to the Trustee, at the option of the Holder by wire transfer to an account designated by the Holder. 
 (b) Subject to the foregoing provisions of this Section 2.12 and Section 2.17, each Debt Security of a particular series delivered under this Indenture upon registration of transfer of, in exchange for or in lieu of any other Debt
Security of the same series shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Debt Security. 
 Section 2.13. Securities Denominated in Dollars. Except as otherwise specified pursuant to Section 2.03 for Debt Securities of any series, payment of the principal of, and premium, if any, and interest on, Debt Securities
of such series will be made in Dollars. 
  

 16 

 Section 2.14. Wire Transfers. Notwithstanding any other provision to the contrary in this
Indenture, the Partnership may make any payment of moneys required to be deposited with the Trustee on account of principal of, or premium, if any, or interest on, the Debt Securities (whether pursuant to optional or mandatory redemption payments,
interest payments or otherwise) by wire transfer in immediately available funds to an account designated by the Trustee before 11:00 a.m., New York City time, on the date such moneys are to be paid to the Holders of the Debt Securities in accordance
with the terms hereof. 
 Section 2.15. Securities Issuable in the Form of a Global Security. 
 (a) If the Partnership shall establish pursuant to Section 2.01 and Section 2.03 that the Debt Securities of a particular series are to be
issued in whole or in part in the form of one or more Global Securities, then the Partnership shall execute and the Trustee or its agent shall, in accordance with Section 2.05, authenticate and deliver, such Global Security or Securities, which
(i) shall represent, and shall be denominated in an amount equal to the aggregate principal amount of, the Outstanding Debt Securities of such series to be represented by such Global Security or Securities, or such portion thereof as the
Partnership shall specify in an Officers’ Certificate, (ii) shall be registered in the name of the Depositary for such Global Security or Securities or its nominee, (iii) shall be delivered by the Trustee or its agent to the
Depositary or pursuant to the Depositary’s instruction and (iv) shall bear a legend substantially to the following effect: 
 “UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), NEW YORK, NEW YORK, TO THE PARTNERSHIP OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE
OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS IS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS MADE TO CEDE & CO., OR TO SUCH OTHER ENTITY AS IS
REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN. 
 TRANSFERS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS IN WHOLE, BUT NOT IN PART, TO NOMINEES OF DTC OR TO A SUCCESSOR THEREOF OR SUCH
SUCCESSOR’S NOMINEE AND TRANSFERS OF PORTIONS OF THIS GLOBAL SECURITY SHALL BE LIMITED TO TRANSFERS MADE IN ACCORDANCE WITH THE RESTRICTIONS SET FORTH IN THE INDENTURE REFERRED TO HEREIN.” 
 or such other legend as may then be required by the Depositary for such Global Security or Securities. 
 (b) Notwithstanding any other provision of this Section 2.15 or of Section 2.07 to the contrary, and subject to the provisions of paragraph
(c) below, unless the terms of a Global Security expressly permit such Global Security to be exchanged in whole or in part for definitive Debt Securities in registered form, a Global Security may be transferred, in whole but not in part and in
the manner provided in Section 2.07, only by the Depositary to a nominee of the Depositary for such Global Security, or by a nominee of the Depositary to the Depositary or another nominee of the Depositary, or by the Depositary or a nominee of
the Depositary to a 

  

 17 

 
successor Depositary for such Global Security selected or approved by the Partnership, or to a nominee of such successor Depositary. 
 (c) (i) If at any time the Depositary for a Global Security or Securities notifies the Partnership that it is unwilling or unable to continue as
Depositary for such Global Security or Securities, or if at any time the Depositary for the Debt Securities for such series shall no longer be eligible or in good standing under the Exchange Act or other applicable statute, rule or regulation, the
Partnership shall appoint a successor Depositary with respect to such Global Security or Securities. If a successor Depositary for such Global Security or Securities is not appointed by the Partnership within 90 days after the Partnership receives
such notice or becomes aware of such ineligibility, the Partnership shall execute, and the Trustee or its agent, upon receipt of a Partnership Order for the authentication and delivery of such individual Debt Securities of such series in exchange
for such Global Security, will authenticate and deliver, individual Debt Securities of such series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of the Global Security in exchange for such
Global Security or Securities. 
 (ii) The Partnership may at any time and in its sole discretion determine that the Debt
Securities of any series or portion thereof issued or issuable in the form of one or more Global Securities shall no longer be represented by such Global Security or Securities. In such event the Partnership will execute, and the Trustee, upon
receipt of a Partnership Order for the authentication and delivery of individual Debt Securities of such series in exchange in whole or in part for such Global Security, will authenticate and deliver individual Debt Securities of such series of like
tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such series or portion thereof in exchange for such Global Security or Securities. 
 (iii) If specified by the Partnership pursuant to Section 2.01 and Section 2.03 with respect to Debt Securities issued or
issuable in the form of a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for individual Debt Securities of such series of like tenor and terms in definitive form on such
terms as are acceptable to the Partnership, the Trustee and such Depositary. Thereupon the Partnership shall execute, and the Trustee or its agent upon receipt of a Partnership Order for the authentication and delivery of definitive Debt Securities
of such series shall authenticate and deliver, without service charge, (A) to each Person specified by such Depositary, a new Debt Security or Securities of the same series of like tenor and terms and of any authorized denomination as requested
by such Person in aggregate principal amount equal to and in exchange for such Person’s beneficial interest in the Global Security, and (B) to such Depositary, a new Global Security of like tenor and terms and in an authorized denomination
equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Debt Securities delivered to Holders thereof. 
 (iv) In any exchange provided for in any of the preceding three paragraphs, the Partnership will execute and the Trustee or its agent will
authenticate and deliver individual Debt Securities. Upon the exchange of the entire principal amount of a Global 

  

 18 

 
Security for individual Debt Securities, such Global Security shall be canceled by the Trustee or its agent. Except as provided in the preceding paragraph,
Debt Securities issued in exchange for a Global Security pursuant to this Section 2.15 shall be registered in such names and in such authorized denominations as the Depositary for such Global Security, pursuant to instructions from its direct
or indirect participants or otherwise, shall instruct the Trustee or the Registrar. The Trustee or the Registrar shall deliver such Debt Securities to the Persons in whose names such Debt Securities are so registered. 
 (v) Payments in respect of the principal of and interest on any Debt Securities registered in the name of the Depositary or its nominee
will be payable to the Depositary or such nominee in its capacity as the registered owner of such Global Security. The Partnership and the Trustee may treat the Person in whose name the Debt Securities, including the Global Security, are registered
as the owner thereof for the purpose of receiving such payments and for any and all other purposes whatsoever. None of the Partnership, the Trustee, any Registrar, the Paying Agent or any agent of the Partnership or the Trustee will have any
responsibility or liability for any aspect of the records relating to or payments made on account of the beneficial ownership interests of the Global Security by the Depositary or its nominee or any of the Depositary’s direct or indirect
participants, or for maintaining, supervising or reviewing any records of the Depositary, its nominee or any of its direct or indirect participants relating to the beneficial ownership interests of the Global Security, the payments to the beneficial
owners of the Global Security of amounts paid to the Depositary or its nominee, or any other matter relating to the actions and practices of the Depositary, its nominee or any of its direct or indirect participants. None of the Partnership, the
Trustee or any such agent will be liable for any delay by the Depositary, its nominee, or any of its direct or indirect participants in identifying the beneficial owners of the Debt Securities, and the Partnership and the Trustee may conclusively
rely on, and will be protected in relying on, instructions from the Depositary or its nominee for all purposes (including with respect to the registration and delivery, and the respective principal amounts, of the Debt Securities to be issued).

 Section 2.16. Medium Term Securities. Notwithstanding any contrary provision herein, if all Debt Securities of a series are
not to be originally issued at one time, it shall not be necessary for the Partnership to deliver to the Trustee an Officers’ Certificate, resolutions of the Board of Directors, a supplemental indenture, an Opinion of Counsel or a written order
or any other document otherwise required pursuant to Section 2.01, Section 2.03, Section 2.05 or Section 15.05 at or prior to the time of authentication of each Debt Security of such series if such documents are delivered to the
Trustee or its agent at or prior to the authentication upon original issuance of the first such Debt Security of such series to be issued; provided that any subsequent request by the Partnership to the Trustee to authenticate Debt Securities
of such series upon original issuance shall constitute a representation and warranty by the Partnership that, as of the date of such request, the statements made in the Officers’ Certificate delivered pursuant to Section 2.05 or
Section 15.05 shall be true and correct as if made on such date. 
 A Partnership Order delivered by the Partnership to the Trustee in
the circumstances set forth in the preceding paragraph may provide that Debt Securities that are the subject thereof will be authenticated and delivered by the Trustee or its agent on original issue from time to time 

  

 19 

 
upon the telephonic or written order of Persons designated in such written order (any such telephonic instructions to be promptly confirmed in writing by
such Person) and that such Persons are authorized to determine, consistent with the Officers’ Certificate, supplemental indenture or resolution of the Board of Directors relating to such written order, such terms and conditions of such Debt
Securities as are specified in such Officers’ Certificate, supplemental indenture or such resolution. 
 Section 2.17. Defaulted
Interest. Any interest on any Debt Security of a particular series which is payable, but is not punctually paid or duly provided for on the dates and in the manner provided in the Debt Securities of such series and in this Indenture (herein
called “Defaulted Interest”) shall forthwith cease to be payable to the Holder thereof on the relevant record date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Partnership, at its election in each
case, as provided in clause (a) or (b) below: 
 (a) The Partnership may elect to make payment of any Defaulted Interest to the
Persons in whose names the Debt Securities of such series are registered at the close of business on a special record date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Partnership shall notify the
Trustee in writing of the amount of Defaulted Interest proposed to be paid on each such Debt Security of such series and the date of the proposed payment, and at the same time the Partnership shall deposit with the Trustee an amount of money equal
to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record date for the payment of such Defaulted Interest, which shall be not more than 15 days and not less than 10
days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Partnership of such special record date and, in the name and at
the expense of the Partnership, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first class postage pre-paid, to each Holder thereof at its address as it appears in the Debt
Security Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in
whose names the Debt Securities of such series are registered at the close of business on such special record date. 
 (b) The Partnership
may make payment of any Defaulted Interest on the Debt Securities of such series in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Debt Securities of such series may be listed, and upon such
notice as may be required by such exchange if, after notice given by the Partnership to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Section 2.18. CUSIP Numbers. The Partnership in issuing the Debt Securities may use “CUSIP” numbers (if then generally in use),
and, if so, the Trustee shall use “CUSIP” numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the accuracy of such numbers either as printed on
the Debt 

  

 20 

 
Securities or as contained in any notice of a redemption, that reliance may be placed only on the other identification numbers printed on the Debt
Securities, and that any such redemption shall not be affected by any defect in or omission of such numbers. The Partnership will promptly notify the Trustee in writing of any change in the “CUSIP” numbers. 
 ARTICLE III 
 REDEMPTION OF
DEBT SECURITIES 
 Section 3.01. Applicability of Article. The provisions of this Article shall be applicable to the Debt
Securities of any series which are redeemable before their Stated Maturity except as otherwise specified as contemplated by Section 2.03 for Debt Securities of such series. 
 Section 3.02. Notice of Redemption; Selection of Debt Securities. In case the Partnership shall desire to exercise the right to redeem all
or, as the case may be, any part of the Debt Securities of any series in accordance with their terms, pursuant to a resolution of the Board of Directors or a supplemental indenture, the Partnership shall fix a date for redemption and shall give
notice of such redemption at least 30 and not more than 60 days prior to the date fixed for redemption to the Holders of Debt Securities of such series to be redeemed as a whole or in part, in the manner provided in Section 15.03. The notice if
given in the manner herein provided shall be conclusively presumed to have been duly given, whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Debt Security of a
series designated for redemption as a whole or in part shall not affect the validity of the proceedings for the redemption of any other Debt Security of such series. 
 Each such notice of redemption shall specify the date fixed for redemption, the redemption price at which Debt Securities of such series are to be redeemed (or the method of calculating such redemption price), the
Place or Places of Payment that payment will be made upon presentation and surrender of such Debt Securities, that any interest accrued to the date fixed for redemption will be paid as specified in said notice, that the redemption is for a sinking
fund payment (if applicable), that, unless otherwise specified in such notice, if the Partnership defaults in making such redemption payment, the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture, that on
and after said date any interest thereon or on the portions thereof to be redeemed will cease to accrue, that, in the case of Original Issue Discount Securities original issue discount accrued after the date fixed for redemption will cease to
accrue, the terms pursuant to which the Debt Securities of that series are being redeemed and that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Debt Securities of
that series. If less than all the Debt Securities of a series are to be redeemed, the notice of redemption shall specify the certificate numbers of the Debt Securities of that series to be redeemed. In case any Debt Security of a series is to be
redeemed in part only, the notice of redemption shall state the portion of the principal amount thereof to be redeemed and shall state that on and after the date fixed for redemption, upon surrender of such Debt Security, a new Debt Security or Debt
Securities of that series in principal amount equal to the unredeemed portion thereof, will be issued. 
 At least 30 days but not more than
60 days before the Redemption Date (unless the Trustee consents to a shorter period), the Partnership shall give written notice to the Trustee of the Redemption Date, the principal amount of Debt Securities to be redeemed and the series and 

  

 21 

 
terms of the Debt Securities pursuant to which such redemption will occur. Such notice shall be accompanied by an Officers’ Certificate and an Opinion
of Counsel from the Partnership to the effect that such redemption will comply with the conditions herein. If fewer than all the Debt Securities of a series are to be redeemed, the record date relating to such redemption shall be selected by the
Partnership and given in writing to the Trustee, which record date shall be not less than 15 days after the date of notice to the Trustee. 
 By 11:00 a.m., New York City time, on the Redemption Date for any Debt Securities, the Partnership shall deposit with the Trustee or with a Paying Agent (or, if the Partnership is acting as its own Paying Agent, segregate and hold in trust)
an amount of money in Dollars (except as provided pursuant to Section 2.03) sufficient to pay the redemption price of such Debt Securities or any portions thereof that are to be redeemed on that date, together with any interest accrued to the
Redemption Date. 
 If less than all the Debt Securities of a series are to be redeemed, the Trustee shall select, on a pro rata basis, by
lot or by such other method as in its sole discretion it shall deem appropriate and fair, the Debt Securities of that series or portions thereof (in multiples of $1,000) to be redeemed. In any case where more than one Debt Security of such series is
registered in the same name, the Trustee in its discretion may treat the aggregate principal amount so registered as if it were represented by one Debt Security of such series. The Trustee shall promptly notify the Partnership in writing of the Debt
Securities selected for redemption and, in the case of any Debt Securities selected for partial redemption, the principal amount thereof to be redeemed. If any Debt Security called for redemption shall not be so paid upon surrender thereof on such
Redemption Date, the principal, premium, if any, and interest shall bear interest until paid from the Redemption Date at the rate borne by the Debt Securities of that series. Provisions of this Indenture that apply to Debt Securities called for
redemption also apply to portions of Debt Securities called for redemption. 
 Section 3.03. Payment of Debt Securities Called for
Redemption. If notice of redemption has been given as provided in Section 3.02, the Debt Securities or portions of Debt Securities of the series with respect to which such notice has been given shall become due and payable on the date and
at the Place or Places of Payment stated in such notice at the applicable redemption price, together with any interest accrued to the date fixed for redemption, and on and after said date (unless the Partnership shall default in the payment of such
Debt Securities at the applicable redemption price, together with any interest accrued to said date) any interest on the Debt Securities or portions of Debt Securities of any series so called for redemption shall cease to accrue, and any original
issue discount in the case of Original Issue Discount Securities shall cease to accrue. On presentation and surrender of such Debt Securities at the Place or Places of Payment specified in said notice, the Debt Securities or the specified portions
thereof shall be paid and redeemed by the Partnership at the applicable redemption price, together with any interest accrued thereon to the date fixed for redemption. 
 Any Debt Security that is to be redeemed only in part shall be surrendered at the corporate trust office or such other office or agency of the Partnership as is specified pursuant to Section 2.03 with, if the
Partnership, the Registrar or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Partnership, the Registrar and the Trustee, duly executed by the Holder thereof or his attorney duly
authorized in writing, and 

  

 22 

 
the Partnership shall execute, and the Trustee shall authenticate and deliver to the Holder of such Debt Security without service charge a new Debt Security
or Debt Securities of the same series, of like tenor and form, of any authorized denomination as requested by such Holder in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Debt Security so
surrendered; except that if a Global Security is so surrendered, the Partnership shall execute, and the Trustee shall authenticate and deliver to the Depositary for such Global Security, without service charge, a new Global Security in a
denomination equal to and in exchange for the unredeemed portion of the principal of the Global Security so surrendered. In the case of a Debt Security providing appropriate space for such notation, at the option of the Holder thereof, the Trustee,
in lieu of delivering a new Debt Security or Debt Securities as aforesaid, may make a notation on such Debt Security of the payment of the redeemed portion thereof. 
 Section 3.04. Mandatory and Optional Sinking Funds. The minimum amount of any sinking fund payment provided for by the terms of Debt Securities of any series, a resolution of the Board of Directors or a
supplemental indenture is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Debt Securities of any series, a resolution of the Board of Directors or a
supplemental indenture is herein referred to as an “optional sinking fund payment.” 
 In lieu of making all or any part of any
mandatory sinking fund payment with respect to any Debt Securities of a series in cash, the Partnership may at its option (a) deliver to the Trustee Debt Securities of that series theretofore purchased or otherwise acquired by the Partnership
or (b) receive credit for the principal amount of Debt Securities of that series which have been redeemed either at the election of the Partnership pursuant to the terms of such Debt Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Debt Securities, resolution or supplemental indenture; provided that such Debt Securities have not been previously so credited. Such Debt Securities shall be received and credited for such
purpose by the Trustee at the redemption price specified in such Debt Securities, resolution or supplemental indenture for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced
accordingly. 
 Section 3.05. Redemption of Debt Securities for Sinking Fund. Not less than 60 days prior to each sinking fund
payment date for any series of Debt Securities, the Partnership will deliver to the Trustee an Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms of that series, any
resolution or supplemental indenture, the portion thereof, if any, which is to be satisfied by payment of cash and the portion thereof, if any, which is to be satisfied by delivering and crediting Debt Securities of that series pursuant to this
Section 3.05 (which Debt Securities, if not previously redeemed, will accompany such certificate) and whether the Partnership intends to exercise its right to make any permitted optional sinking fund payment with respect to such series. Such
certificate shall also state that no Event of Default has occurred and is continuing with respect to such series. Such certificate shall be irrevocable and upon its delivery the Partnership shall be obligated to make the cash payment or payments
therein referred to, if any, by 11 a.m., New York City time, on the next succeeding sinking fund payment date. Failure of the Partnership to deliver such certificate (or to deliver the Debt Securities specified in this paragraph) shall not
constitute a Default, but such failure shall require that the sinking fund payment due on the next succeeding sinking fund 

  

 23 

 
payment date for that series shall be paid entirely in cash and shall be sufficient to redeem the principal amount of such Debt Securities subject to a
mandatory sinking fund payment without the option to deliver or credit Debt Securities as provided in this Section 3.05 and without the right to make any optional sinking fund payment, if any, with respect to such series. 
 Any sinking fund payment (mandatory or optional) made in cash plus any unused balance of any preceding sinking fund payments made in cash which shall
equal or exceed $100,000 (or a lesser sum if the Partnership shall so request) with respect to the Debt Securities of any particular series shall be applied by the Trustee on the sinking fund payment date on which such payment is made (or, if such
payment is made before a sinking fund payment date, on the sinking fund payment date following the date of such payment) to the redemption of such Debt Securities at the redemption price specified in such Debt Securities, resolution or supplemental
indenture for operation of the sinking fund together with any accrued interest to the date fixed for redemption. Any sinking fund moneys not so applied or allocated by the Trustee to the redemption of Debt Securities shall be added to the next cash
sinking fund payment received by the Trustee for such series and, together with such payment, shall be applied in accordance with the provisions of this Section 3.05. Any and all sinking fund moneys with respect to the Debt Securities of any
particular series held by the Trustee on the last sinking fund payment date with respect to Debt Securities of such series and not held for the payment or redemption of particular Debt Securities shall be applied by the Trustee, together with other
moneys, if necessary, to be deposited sufficient for the purpose, to the payment of the principal of the Debt Securities of that series at its Stated Maturity. 
 The Trustee shall select the Debt Securities to be redeemed upon such sinking fund payment date in the manner specified in the last paragraph of Section 3.02, and the Partnership shall cause notice of the
redemption thereof to be given in the manner provided in Section 3.02 except that the notice of redemption shall also state that the Debt Securities are being redeemed by operation of the sinking fund. Such notice having been duly given, the
redemption of such Debt Securities shall be made upon the terms and in the manner stated in Section 3.03. 
 The Trustee shall not
redeem any Debt Securities of a series with sinking fund moneys or mail any notice of redemption of such Debt Securities by operation of the sinking fund for such series during the continuance of a Default in payment of interest on such Debt
Securities or of any Event of Default (other than an Event of Default occurring as a consequence of this paragraph) with respect to such Debt Securities, except that if the notice of redemption of any such Debt Securities shall theretofore have been
mailed in accordance with the provisions hereof, the Trustee shall redeem such Debt Securities if cash sufficient for that purpose shall be deposited with the Trustee for that purpose in accordance with the terms of this Article III. Except as
aforesaid, any moneys in the sinking fund for such series at the time when any such Default or Event of Default shall occur and any moneys thereafter paid into such sinking fund shall, during the continuance of such Default or Event of Default, be
held as security for the payment of such Debt Securities; provided, however, that in case such Default or Event of Default shall have been cured or waived as provided herein, such moneys shall thereafter be applied on the next sinking fund
payment date for such Debt Securities on which such moneys may be applied pursuant to the provisions of this Section 3.05. 
  

 24 

 ARTICLE IV 
 COVENANTS 
 Section 4.01. Payment of Principal of, and Premium, If Any, and Interest
on, Debt Securities. The Partnership, for the benefit of each series of Debt Securities, will duly and punctually pay or cause to be paid the principal of, and premium, if any, and interest on, each of the Debt Securities at the place, at the
respective times and in the manner provided herein or in the Debt Securities. Each installment of interest on the Debt Securities may at the Partnership’s option be paid by mailing checks for such interest payable to the Person entitled thereto
pursuant to Section 2.07(a) to the address of such Person as it appears on the Debt Security Register. 
 Principal, premium and
interest of Debt Securities of any series shall be considered paid on the date due if, by 11:00 a.m., New York City time, on such date the Trustee or any Paying Agent holds in accordance with this Indenture money sufficient to pay all principal,
premium and interest then due. 
 The Partnership shall pay interest on overdue principal or premium, if any, at the rate specified therefor
in the Debt Securities, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful. 
 Section 4.02. Maintenance of Offices or Agencies for Registration of Transfer, Exchange and Payment of Debt Securities. For the benefit of each series of Debt Securities, the Partnership will maintain an office or agency where
Debt Securities of such series may be presented or surrendered for payment, and it shall also maintain (in or outside such Place of Payment) an office or agency where Debt Securities of such series may be surrendered for transfer or exchange and
where notices and demands to or upon the Partnership in respect of the Debt Securities of such series and this Indenture may be served. The Partnership will give prompt written notice to the Trustee of the location, and any change in the location,
of such office or agency. If at any time the Partnership shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or
served at the office of the Trustee where its corporate trust business is principally administered in the United States of America, and the Partnership hereby appoints the Trustee as its agent to receive all presentations, surrenders, notices and
demands. 
 The Partnership may also from time to time designate different or additional offices or agencies to be maintained for such
purposes (in or outside of such Place of Payment) and may from time to time rescind any such designation. The Partnership hereby designates the office of the Trustee at N9303-110 MAC, Sixth & Marquette, Minneapolis, MN 55479 as its initial
office or agency for such purpose. The Partnership will give prompt written notice to the Trustee of any such additional designation or rescission of designation and any change in the location of any such different or additional office or agency.

 Section 4.03. Appointment to Fill a Vacancy in the Office of Trustee. The Partnership, whenever necessary to avoid or fill a
vacancy in the office of Trustee, will appoint, in the manner provided in Section 7.08, a Trustee so that there shall at all times be a Trustee hereunder with respect to each series of Debt Securities. 
  

 25 

 Section 4.04. Duties of Paying Agents, etc. 
 (a) The Partnership shall cause each Paying Agent, if any, other than the Trustee, to execute and deliver to the Trustee an instrument in which such
Paying Agent shall agree with the Trustee, subject to the provisions of this Section 4.04, that: 
 (i) it will hold all
sums held by it as such agent for the payment of the principal of, and premium, if any, or interest on, the Debt Securities of any series (whether such sums have been paid to it by the Partnership or by any other obligor on the Debt Securities of
such series) in trust for the benefit of the Holders of the Debt Securities of such series; 
 (ii) it will give the Trustee
notice of any failure by the Partnership (or by any other obligor on the Debt Securities of such series) to make any payment of the principal of, and premium, if any, or interest on, the Debt Securities of such series when the same shall be due and
payable; and 
 (iii) it will at any time during the continuance of an Event of Default, upon the written request of the
Trustee, forthwith pay to the Trustee all sums so held by it as such agent. 
 (b) If the Partnership shall act as its own Paying Agent, it
will, on or before each due date of the principal of, and premium, if any, or interest on, the Debt Securities of any series, set aside, segregate and hold in trust for the benefit of the Holders of the Debt Securities of such series a sum
sufficient to pay such principal, premium, if any, or interest so becoming due. The Partnership will promptly notify the Trustee of any failure by the Partnership to take such action or the failure by any other obligor on such Debt Securities to
make any payment of the principal of, and premium, if any, or interest on, such Debt Securities when the same shall be due and payable. 
 (c) Anything in this Section 4.04 to the contrary notwithstanding, the Partnership may, at any time, for the purpose of obtaining a satisfaction and discharge of this Indenture, or for any other reason, pay or cause to be paid to the
Trustee all sums held in trust by it or any Paying Agent, as required by this Section 4.04, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Partnership or such Paying Agent. 
 (d) Whenever the Partnership shall have one or more Paying Agents with respect to any series of Debt Securities, it will, prior to each due date of the
principal of, and premium, if any, or interest on, any Debt Securities of such series, deposit with any such Paying Agent a sum sufficient to pay the principal, premium or interest so becoming due, such sum to be held in trust for the benefit of the
Persons entitled thereto, and (unless any such Paying Agent is the Trustee) the Partnership will promptly notify the Trustee of its action or failure so to act. 
 Anything in this Section 4.04 to the contrary notwithstanding, the agreement to hold sums in trust as provided in this Section 4.04 is subject to the provisions of Section 11.05.

 Section 4.05. Compliance Certificate. 
 (a) The Partnership shall, so long as any Debt Securities are outstanding, deliver to the Trustee, within 150 days after the end of each fiscal year of
the Partnership, commencing with its fiscal year ending after the date hereof, an Officers’ Certificate as to such officers’ knowledge of the compliance by the Partnership with all conditions and covenants under this Indenture. For
purposes of this Section 4.05(a), such compliance shall be determined without regard to any grace period or notice requirement under this Indenture. 
 (b) The Partnership shall, so long as any of the Debt Securities are outstanding, deliver to the Trustee within 30 days after the occurrence of any Default or Event of Default under this Indenture, an Officers’
Certificate specifying such Default or Event of Default, the status thereof and what action the Partnership and any Guarantor is taking or proposes to take with respect thereto. 
 Section 4.06. Payment of Additional Amounts. Unless otherwise required by Canadian law, neither the Partnership nor any Guarantor will deduct
or withhold from payments made with respect to the Debt Securities or any Guarantee on account of any present or future Taxes. In the event that either the Partnership or a Guarantor is required to withhold or deduct on account of any Taxes due from
any payment made under or with respect to the Debt Securities or a Guarantee, as the case may be, the Partnership or such Guarantor, as the case may be, will pay such additional amounts (“Additional Amounts”) as may be necessary so that
the net amount received by each Holder of Debt Securities will equal the amount that the Holder would have received if the Taxes had not been required to be withheld or deducted; provided, however, that no Additional Amounts will be
payable with respect to a payment made to a Holder (A) who, insofar as Canadian Taxes are relevant, does not deal at arm’s length (within the meaning of the Income Tax Act (Canada)) with the Partnership or such Guarantor or (B) to the
extent: (i) that any Taxes would not have been so imposed but for the existence of any present or former connection between the Holder and Canada or any province or territory of Canada, other than the mere receipt of the payment, the
acquisition, ownership or disposition of such Debt Securities or the exercise or enforcement of rights under the Debt Securities, any Guarantee or this Indenture; (ii) of any estate, inheritance, gift, sales, transfer or personal property Taxes
imposed with respect to the Debt Securities, except as described below or as otherwise provided in this Indenture; (iii) that any such Taxes would not have been imposed but for the presentation of the Debt Securities, where presentation is
required, for payment on a date more than 30 days after the date on which the payment became due and payable or the date on which payment thereof is duly provided for, whichever is later, except to the extent that the beneficiary or Holder thereof
would have been entitled to Additional Amounts had the Debt Securities been presented for payment on any date during such 30-day period; or (iv) that the Holder would not be liable or subject to such withholding or deduction of Taxes but for
the failure to make a valid declaration of non-residence or other similar claim for exemption, if: (a) the making of the declaration or claim is required or imposed by statute, treaty, regulation, ruling or administrative practice of the
relevant taxing authority as a precondition to an exemption from, or reduction in, the relevant Taxes; and (b) at least 60 days prior to the first payment with respect to which the Partnership or any Guarantor shall apply this clause (iv), the
Partnership or such Guarantor shall have notified all Holders of the Debt Securities in writing that they shall be required to provide this declaration or claim. The Partnership and any Guarantor shall also: (i) withhold or deduct such Taxes as

  

 27 

 
required; (ii) remit the full amount of Taxes deducted or withheld to the relevant taxing authority in accordance with all applicable laws;
(iii) use reasonable efforts to obtain from each relevant taxing authority imposing the Taxes certified copies of tax receipts evidencing the payment of any Taxes deducted or withheld; and (iv) upon request, make available to the Holders
of the Debt Securities, within 60 days after the date the payment of any Taxes deducted or withheld is due pursuant to applicable law, certified copies of tax receipts evidencing such payment by the Partnership or such Guarantor and, notwithstanding
the Partnership’s or such Guarantor’s efforts to obtain the receipts, if the same are not obtainable, other evidence of such payments. 
 In addition, the Partnership or any Guarantor will pay any stamp, issue, registration, documentary or other similar taxes and duties, including interest, penalties and additional amounts with respect thereto, payable in Canada or any
political subdivision or taxing authority thereof with respect to the creation, issue, offering, enforcement, redemption or retirement of the Debt Securities or any Guarantee. 
 At least 30 days prior to each date on which any payment under or with respect to the Debt Securities is due and payable, if the Partnership or any
Guarantor becomes obligated to pay Additional Amounts with respect to such payment, the Partnership (or in respect of any Guarantee, the relevant Guarantor) shall deliver to the Trustee an Officers’ Certificate stating the fact that such
Additional Amounts will be payable, the amounts so payable and such other information as is necessary to enable the Trustee to pay such Additional Amounts to the Holders on the payment date. Whenever in this Indenture there is mentioned, in any
context, the payment of principal of, premium, if any, or interest or any other amount payable on or with respect to any of the Debt Securities, such mention shall be deemed to include mention of the payment of Additional Amounts provided for in
this Section 4.06 to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof pursuant to the provisions of this Section 4.06, and express mention of the payment of Additional Amounts in those
provisions hereof shall not be construed as excluding Additional Amounts in those provisions hereof where such express mention is not made (if applicable). 
 The obligations of the Partnership and any Guarantor under this Section 4.06 shall survive the termination of this Indenture and the payment of all amounts under or with respect to this Indenture and the Debt
Securities. 
 The preceding provisions of this Section 4.06 shall apply only at and during such time as either the Partnership or any
Guarantor is organized under the laws of Canada or a province thereof. 
 Section 4.07. SEC Reports; Financial Statements. 

(a) The Partnership shall, so long as any of the Debt Securities are Outstanding: 
 (i) file with the Trustee, within 30 days after it files the same with the SEC, copies of the annual reports and of the information,
documents and other reports which the Partnership may be required to file with the SEC pursuant to the Exchange Act; or if the Partnership is not required to file information with the SEC pursuant to the Exchange Act, file with the Trustee and the
SEC in accordance with rules and regulations 

  

 28 

 
prescribed from time to time by the SEC any supplementary and periodic information, documents and reports which may be required pursuant to the Exchange Act,
in respect of a security listed and registered on a national securities exchange as may be prescribed in such rules and regulations; provided that all such filings shall be deemed made with the Trustee to the extent such information,
documents and other reports are readily available through EDGAR or any successor thereto, as of the date on which such filing is required to be made with the Trustee; and 
 (ii) transmit within 30 days after the filing thereof with the Trustee, in the manner and to the extent provided in Section 313(c) of
the Trust Indenture Act, such summaries of any information, documents and reports required to be filed by the Partnership pursuant to paragraph (i) of this Section as may be required by rules and regulations prescribed from time to time by the
SEC. 
 (b) The Partnership and each Guarantor (if any) shall also comply with the provisions of TIA Section 314(a). 
 (c) The Partnership shall provide the Trustee with a sufficient number of copies of all reports and other documents and information that the Trustee may
be required to deliver to Holders under this Section. Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained therein, including the Partnership’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’
Certificates). 
 Section 4.08. Existence. Subject to Article X, the Partnership will do or cause to be done all things necessary
to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Partnership shall not be required to preserve any such right or franchise if it shall determine that the
preservation thereof is no longer desirable in the conduct of the business of the Partnership. 
 Section 4.09. Waiver of Certain
Covenants. The Partnership may, with respect to the Debt Securities of any series, omit in any particular instance to comply with any covenant set forth in this Article IV (except Section 4.01 through Section 4.06) or made
applicable to such Debt Securities pursuant to Section 2.03, if, before or after the time for such compliance, the Holders of at least a majority in principal amount of the Outstanding Debt Securities of each series affected, waive such
compliance in such instance with such covenant, but no such waiver shall extend to or affect such covenant except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Partnership and any Guarantor
and the duties of the Trustee in respect of any such covenant shall remain in full force and effect. 
 ARTICLE V 
 HOLDERS’ LISTS AND REPORTS BY THE TRUSTEE 
 Section 5.01. Partnership to Furnish Trustee Information as to Names and Addresses of Holders; Preservation of Information. The Partnership covenants and agrees that it will furnish or cause to be furnished to
the Trustee with respect to the Debt Securities of each series: 
 (a) not more than 10 days after each record date with respect to the
payment of interest, if any, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Holders as of such record date, and 
  

 29 

 (b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the
Partnership of any such request, a list of similar form and contents as of a date not more than 15 days prior to the time such list is furnished; 
 provided, however, that so long as the Trustee shall be the Registrar, such lists shall not be required to be furnished. 
 The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the Holders (i) contained in the most recent list furnished to it as provided in this Section 5.01 or
(ii) received by it in the capacity of Paying Agent or Registrar (if so acting) hereunder. 
 The Trustee may destroy any list furnished
to it as provided in this Section 5.01 upon receipt of a new list so furnished. 
 Section 5.02. Communications to Holders.
Holders may communicate pursuant to Section 312(b) of the TIA with other Holders with respect to their rights under this Indenture or the Debt Securities. The Partnership, the Trustee, the Registrar and anyone else shall have the protection of
Section 312(c) of the TIA. 
 Section 5.03. Reports by Trustee. Within 60 days after each May 15 (beginning with the first
May 15 following the first issuance of the first series of Debt Securities hereunder) the Trustee shall mail to Holders a brief report dated as of such May 15 that complies with TIA Section 313(a); provided, however, that if no
event described in TIA Section 313(a) has occurred within the twelve months preceding the reporting date, no report need be transmitted. The Trustee also shall comply with TIA Section 313(b). Reports pursuant to this Section 5.03
shall be transmitted by mail (a) to all Holders, as the names and addresses of such Holders appear in the Debt Security Register, and (b) except in the cases of reports under Section 313(b)(2) of the TIA, to each Holder of a Debt
Security of any series whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 5.01. 
 A copy of each report at the time of its mailing to Holders shall be filed by the Trustee with the Partnership, the SEC and each stock exchange (if any) on which the Debt Securities of any series are listed. The Partnership agrees to notify
promptly the Trustee whenever the Debt Securities of any series become listed on any stock exchange and of any delisting thereof. 
 Section
5.04. Record Dates for Action by Holders. If the Partnership shall solicit from the Holders of Debt Securities of any series any action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or
the taking of any other action), the Partnership may, at its option, fix in advance a record date for the determination of Holders of Debt Securities entitled to take such action, but the Partnership shall have no obligation to do so. Any such
record date shall be fixed at the Partnership’s discretion. If such a record date is fixed, such action may be sought or given before or after the record date, but only the Holders of Debt Securities of record at the close of business on such
record date shall be deemed to be 

  

 30 

 
Holders of Debt Securities for the purpose of determining whether Holders of the requisite proportion of Debt Securities of such series Outstanding have
authorized or agreed or consented to such action, and for that purpose the Debt Securities of such series Outstanding shall be computed as of such record date. 
 ARTICLE VI 
 REMEDIES OF THE TRUSTEE AND HOLDERS IN EVENT OF DEFAULT 
 Section 6.01. Events of Default. If any one or more of the following shall have occurred and be continuing with respect to Debt Securities of
any series (each of the following, an “Event of Default”): 
 (a) default in the payment of any installment of interest upon any
Debt Securities of that series as and when the same shall become due and payable, whether or not such payment shall be prohibited by Article XIII, and continuance of such default for a period of 30 days; or 
 (b) default in the payment of the principal of or premium, if any, on any Debt Securities of that series as and when the same shall become due and
payable, whether at Stated Maturity, upon redemption, by declaration, upon required repurchase or otherwise, whether or not such payment shall be prohibited by Article XIII; or 
 (c) default in the payment of any sinking fund payment with respect to any Debt Securities of that series as and when the same shall become due and
payable; or 
 (d) failure on the part of the Partnership or any Guarantor duly to observe or perform any other of the covenants or
agreements on the part of the Partnership or such Guarantor with respect to the Debt Securities of that series set forth in this Indenture with respect to such series or in any supplemental indenture with respect to such series, or, in the absence
of an applicable supplemental indenture, in any resolution of the Board of Directors authorizing the issuance of that series of Debt Securities (other than a covenant a default in the performance of which is elsewhere in this Section specifically
dealt with), continuing for a period of 90 days after the date on which written notice specifying such failure and requiring the Partnership and such Guarantor to remedy the same shall have been given, by registered or certified mail, to the
Partnership and such Guarantor by the Trustee, or to the Partnership, such Guarantor and the Trustee by the Holders of at least 25% in aggregate principal amount of the Debt Securities of that series at the time Outstanding; or 
 (e) the Partnership or any Guarantor, pursuant to or within the meaning of any Bankruptcy Law: 
 (i) commences a voluntary case; 
 (ii) consents to the entry of an order for relief against it in an involuntary case; 
 (iii)
consents to the appointment of a Custodian of it or for all or substantially all of its property; or 
 (iv) makes a general
assignment for the benefit of its creditors; 
  

 31 

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

 (i) is for relief against the Partnership or any Guarantor as debtor in an involuntary case; 
 (ii) appoints a Custodian of the Partnership or any Guarantor or a Custodian for all or substantially all of the property of the
Partnership or any Guarantor; or 
 (iii) orders the liquidation of the Partnership or any Guarantor; 
 and the order or decree remains unstayed and in effect for 90 days; 
 (g) any default by the Partnership or any of its Subsidiaries in the payment, at the final maturity date and after the expiration of any applicable grace
period, of principal of, premium, if any, or interest on indebtedness for money borrowed in the principal amount then outstanding of $100,000,000 or more, or acceleration of any indebtedness for borrowed money of such amount, such that the
indebtedness becomes due and payable prior to its maturity date and such acceleration is not rescinded within 60 days after notice thereof has been given to the Partnership by the Trustee or to the Partnership and the Trustee by the Holders of at
least 25% in aggregate principal amount of Outstanding Debt Securities of such series; provided that, if, prior to the entry of judgment in favor of the Trustee for payment of the Debt Securities of such series, the default under such indenture or
instrument has been remedied or cured by the Partnership or such Subsidiary, or waived by the holders of such indebtedness, then the Event of Default under the Indenture will be deemed likewise to have been remedied, cured or waived; 
 (h) except as permitted by this Indenture, any Guarantee ceases to be in full force and effect or is declared null and void in a judicial proceeding or
any Guarantor denies or disaffirms its obligations under this Indenture or its Guarantee; or 
 (i) any other Event of Default provided in
any supplemental indenture or, in the absence of an applicable supplemental indenture, in a resolution of the Board of Directors with respect to Debt Securities of that series; 
 then and in each and every case that an Event of Default described in clause (a), (b), (c), (d), (g), (h) or (i) with respect to Debt Securities of that series at the time Outstanding occurs and is
continuing, unless the principal of, premium, if any, and interest on all the Debt Securities of that series shall have already become due and payable, either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Debt
Securities of that series then Outstanding, by notice in writing to the Partnership (and to the Trustee if given by Holders), may declare the principal of (or, if the Debt Securities of that series are Original Issue Discount Debt Securities, such
portion of the principal amount as may be specified in the terms of that series), premium, if any, and interest on all the Debt Securities of that series to be due and payable immediately, and upon any such declaration the same shall become and
shall be immediately due and payable, anything in this Indenture or in the Debt Securities of that series contained to the contrary notwithstanding. If an Event of Default described in clause (e) or (f) occurs, then and in each and every
such case, unless the principal of and interest on all the Debt Securities shall have already become due and payable, the principal of (or, if any Debt Securities are Original Issue 

  

 32 

 
Discount Debt Securities, such portion of the principal amount as may be specified in the terms thereof), premium, if any, and interest on all the Debt
Securities then Outstanding hereunder shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee or any Holders, anything in this Indenture or in the Debt Securities contained to
the contrary notwithstanding. 
 The Holders of a majority in aggregate principal amount of the Debt Securities of a particular series by
written notice to the Trustee may waive all past Defaults (except with respect to the nonpayment of principal, premium, if any, or interest) and rescind an acceleration and its consequences, in each case with respect to the Debt Securities of such
series, if the rescission would not conflict with any judgment or decree of a court of competent jurisdiction already rendered and if all existing Events of Default with respect to the Debt Securities of such series have been cured or waived except
nonpayment of principal, premium, if any, or interest that has become due solely because of acceleration. Upon any such rescission, the parties hereto shall be restored respectively to their several positions and rights hereunder, and all rights,
remedies and powers of the parties hereto shall continue as though no such proceeding had been taken. 
 Section 6.02. Collection of Debt
by Trustee, etc. If an Event of Default occurs and is continuing, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any action or proceedings at law or in equity for the collection of
the sums so due and unpaid or enforce the performance of any provision of the Debt Securities of the affected series or this Indenture, and may prosecute any such action or proceedings to judgment or final decree, and may enforce any such judgment
or final decree against the Partnership or any other obligor upon the Debt Securities of such series (and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Partnership or any other obligor
upon the Debt Securities of such series, wherever situated). 
 In case there shall be pending proceedings for the bankruptcy or for the
reorganization of the Partnership or any other obligor upon the Debt Securities of any series under any Bankruptcy Law, or in case a Custodian shall have been appointed for its property, or in case of any other similar judicial proceedings relative
to the Partnership or any other obligor upon the Debt Securities of any series, its creditors or its property, the Trustee, irrespective of whether the principal of Debt Securities of any series shall then be due and payable as therein expressed or
by declaration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 6.02, shall be entitled and empowered, by intervention in such proceedings or otherwise, to file and prove
a claim or claims for the whole amount of principal, premium, if any, and interest (or, if the Debt Securities of such series are Original Issue Discount Debt Securities, such portion of the principal amount as may be specified in the terms of such
series) owing and unpaid in respect of the Debt Securities of such series, and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation to the
Trustee, its agents, attorneys and counsel, and for reimbursement of all expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith) and of the Holders thereof allowed in any such
judicial proceedings relative to the Partnership, or any other obligor upon the Debt Securities of such series, its creditors or its property, and to collect and receive any moneys or other property payable or deliverable on any such claims, and to
distribute all amounts received with respect to the claims of such Holders and of the Trustee on their behalf, 

  

 33 

 
and any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of such Holders to make payments to the Trustee, and, in
the event that the Trustee shall consent to the making of payments directly to such Holders, to pay to the Trustee such amount as shall be sufficient to cover reasonable compensation to the Trustee, its agents, attorneys and counsel, and all other
reasonable expenses and liabilities incurred, and all advances made, by the Trustee except as a result of its negligence or bad faith. 
 All
rights of action and of asserting claims under this Indenture, or under any of the Debt Securities of any series, may be enforced by the Trustee without the possession of any such Debt Securities, or the production thereof in any trial or other
proceedings relative thereto, and any such action or proceedings instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment (except for any amounts payable to the Trustee pursuant to
Section 7.06) shall be for the ratable benefit of the Holders of all the Debt Securities in respect of which such action was taken. 
 In case of an Event of Default hereunder, the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to
protect and enforce any of such rights, either at law or in equity or in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in this
Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law. 
 Section 6.03.
Application of Moneys Collected by Trustee. Any moneys or other property collected by the Trustee pursuant to Section 6.02 with respect to Debt Securities of any series shall be applied, after giving effect to the provisions of
Article XIII, in the following order, at the date or dates fixed by the Trustee for the distribution of such moneys or other property, upon presentation of the several Debt Securities of such series in respect of which moneys or other property
have been collected, and the notation thereon of the payment, if only partially paid, and upon surrender thereof if fully paid: 
 FIRST: To
the payment of all money due the Trustee pursuant to Section 7.06; 
 SECOND: In case the principal of the Outstanding Debt Securities
in respect of which such moneys have been collected shall not have become due, to the payment of interest on the Debt Securities of such series in the order of the maturity of the installments of such interest, with interest (to the extent that such
interest has been collected by the Trustee) upon the overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue Discount Debt Securities) borne by the Debt Securities of such series, such payments to be made
ratably to the Persons entitled thereto, without discrimination or preference; 
 THIRD: In case the principal of the Outstanding Debt
Securities in respect of which such moneys have been collected shall have become due, by declaration or otherwise, to the payment of the whole amount then owing and unpaid upon the Debt Securities of such series for principal and premium, if any,
and interest, with interest on the overdue principal and premium, if any, and (to the extent that such interest has been collected by the Trustee) upon overdue installments of interest at the rate or Yield to Maturity (in the case of Original Issue
Discount Debt Securities) 

  

 34 

 
borne by the Debt Securities of such series; and, in case such moneys shall be insufficient to pay in full the whole amount so due and unpaid upon the Debt
Securities of such series, then to the payment of such principal and premium, if any, and interest, without preference or priority of principal and premium, if any, over interest, or of interest over principal and premium, if any, or of any
installment of interest over any other installment of interest, or of any Debt Security of such series over any Debt Security of such series, ratably to the aggregate of such principal and premium, if any, and interest; and 
 FOURTH: The remainder, if any, shall be paid to the Partnership, its successors or assigns, or to whomsoever may be lawfully entitled to receive the
same, or as a court of competent jurisdiction may direct. 
 The Trustee may fix a record date and payment date for any payment to Holders
pursuant to this Section 6.03. At least 15 days before such record date, the Partnership shall mail to each Holder and the Trustee a notice that states the record date, the payment date and amount to be paid. 
 Section 6.04. Limitation on Suits by Holders. No Holder of any Debt Security of any series shall have any right by virtue or by availing of any
provision of this Indenture to institute any action or proceeding at law or in equity or in bankruptcy or otherwise, upon or under or with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder,
unless such Holder previously shall have given to the Trustee written notice of an Event of Default with respect to Debt Securities of that same series and of the continuance thereof and unless the Holders of not less than 25% in aggregate principal
amount of the Outstanding Debt Securities of that series shall have made written request upon the Trustee to institute such action or proceedings in respect of such Event of Default in its own name as Trustee hereunder and shall have offered to the
Trustee such reasonable indemnity or security as it may require against the costs, expenses and liabilities to be incurred therein or thereby, and the Trustee, for 60 days after its receipt of such notice, request and offer of indemnity or security
shall have failed to institute any such action or proceedings and no direction inconsistent with such written request shall have been given to the Trustee pursuant to Section 6.06; it being understood and intended, and being expressly
covenanted by the Holder of every Debt Security with every other Holder and the Trustee, that no one or more Holders shall have any right in any manner whatever by virtue or by availing of any provision of this Indenture to affect, disturb or
prejudice the rights of any Holders, or to obtain or seek to obtain priority over or preference to any other such Holder, or to enforce any right under this Indenture, except in the manner herein provided and for the equal, ratable and common
benefit of all such Holders. For the protection and enforcement of the provisions of this Section 6.04, each and every Holder and the Trustee shall be entitled to such relief as can be given either at law or in equity. 
 Notwithstanding any other provision in this Indenture, however, the right of any Holder of any Debt Security to receive payment of the principal of, and
premium, if any, and (subject to Section 2.12) interest on, such Debt Security, on or after the respective due dates expressed in such Debt Security, and to institute suit for the enforcement of any such payment on or after such respective
dates, shall not be impaired or affected without the consent of such Holder. 
  

 35 

 Section 6.05. Remedies Cumulative; Delay or Omission in Exercise of Rights Not a Waiver of
Default. All powers and remedies given by this Article VI to the Trustee or to the Holders shall, to the extent permitted by law, be deemed cumulative and not exclusive of any thereof or of any other powers and remedies available to the
Trustee or the Holders, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements contained in this Indenture, and to the extent permitted by law, no delay or omission of the Trustee or of any
Holder to exercise any right or power accruing upon any Default occurring and continuing as aforesaid, shall impair any such right or power, or shall be construed to be a waiver of any such Default or an acquiescence therein; and, subject to the
provisions of Section 6.04, to the extent permitted by law, every power and remedy given by this Article VI or by law to the Trustee or to the Holders may be exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Holders. 
 Section 6.06. Rights of Holders of Majority in Principal Amount of Debt Securities to Direct Trustee and to
Waive Default. The Holders of a majority in aggregate principal amount of the Debt Securities of any series at the time Outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any remedy available
to the Trustee, or exercising any right, trust or power conferred on the Trustee, with respect to the Debt Securities of such series; provided, however, that such direction shall not be otherwise than in accordance with law and the provisions
of this Indenture, and that subject to the provisions of Section 7.01, the Trustee shall have the right to decline to follow any such direction if the Trustee being advised by counsel shall determine that the action so directed may not lawfully
be taken, or if the Trustee shall by a responsible officer or officers determine that the action so directed would involve it in personal liability or would be unduly prejudicial to Holders of Debt Securities of such series not taking part in such
direction; and provided, further, that nothing in this Indenture contained shall impair the right of the Trustee to take any action deemed proper by the Trustee and which is not inconsistent with such direction by such Holders. Prior to the
acceleration of the maturity of the Debt Securities of any series, as provided in Section 6.01, the Holders of a majority in aggregate principal amount of the Debt Securities of that series at the time Outstanding may on behalf of the Holders
of all the Debt Securities of that series waive any past Default or Event of Default and its consequences for that series, except a Default in the payment of the principal of, and premium, if any, or interest on, any of the Debt Securities and a
Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected thereby. In case of any such waiver, such Default shall cease to exist, any Event of Default arising therefrom shall be
deemed to have been cured for every purpose of this Indenture, and the Partnership, the Trustee and the Holders of the Debt Securities of that series shall be restored to their former positions and rights hereunder, respectively; but no such waiver
shall extend to any subsequent or other Default or impair any right consequent thereon. 
 Section 6.07. Trustee to Give Notice of
Defaults Known to It, but May Withhold Such Notice in Certain Circumstances. The Trustee shall, within 90 days after the occurrence of a Default, or if later, within 30 days after the Trustee obtains actual knowledge of the Default, with respect
to a series of Debt Securities give to the Holders thereof, in the manner provided in Section 15.03, notice of all Defaults with respect to such series known to the Trustee, unless such Defaults shall have been cured or waived before the giving
of such notice; provided that, except in the case of Default in the payment of the principal of, or premium, if any, or interest on, any of the Debt Securities of such series or in the making of any sinking fund payment with respect to

  

 36 

 
the Debt Securities of such series, the Trustee shall be protected in withholding such notice if and so long as the board of directors, the executive
committee or a committee of directors or responsible officers of the Trustee in good faith determine that the withholding of such notice is in the interests of the Holders thereof. 
 Section 6.08. Requirement of an Undertaking to Pay Costs in Certain Suits under the Indenture or Against the Trustee. All parties to this
Indenture agree, and each Holder of any Debt Security by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit in the manner and to the extent provided in the TIA, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys’ fees and expenses, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the
provisions of this Section 6.08 shall not apply to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 25 percent in principal amount of the Outstanding Debt
Securities of that series or to any suit instituted by any Holder for the enforcement of the payment of the principal of, or premium, if any, or interest on, any Debt Security on or after the due date for such payment expressed in such Debt
Security. 
 ARTICLE VII 
 CONCERNING THE TRUSTEE 
 Section 7.01. Certain Duties and Responsibilities. The Trustee, prior to the
occurrence of an Event of Default and after the curing or waiving of all Events of Default which may have occurred, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture. In case an Event of Default
has occurred (which has not been cured or waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in their exercise as a prudent man would exercise or use under the
circumstances in the conduct of his own affairs. 
 No provision of this Indenture shall be construed to relieve the Trustee from liability
for its own negligent action, negligent failure to act, bad faith or willful misconduct, except that: 
 (a) this paragraph shall not be
construed to limit the effect of the first paragraph of this Section 7.01; 
 (b) prior to the occurrence of an Event of Default with
respect to the Debt Securities of a series and after the curing or waiving of all Events of Default with respect to such series which may have occurred: 
 (i) the duties and obligations of the Trustee with respect to Debt Securities of any series shall be determined solely by the express provisions of this Indenture, and the Trustee shall not be liable except for the
performance of such duties and obligations with respect to such series as are specifically set forth in this Indenture, and no implied covenants or obligations with respect to such series shall be read into this Indenture against the Trustee;

  

 37 

 (ii) in the absence of bad faith on the part of the Trustee, the Trustee may conclusively
rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates
or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture; but the Trustee
shall examine the evidence furnished to it pursuant to Section 4.05 and Section 4.06 to determine whether or not such evidence conforms to the requirement of this Indenture; 
 (iii) the Trustee shall not be liable for an error of judgment made in good faith by a responsible officer, unless it shall be proved that
the Trustee was negligent in ascertaining the pertinent facts; and 
 (iv) the Trustee shall not be liable with respect to any
action taken or omitted to be taken by it with respect to Debt Securities of any series in good faith in accordance with the direction of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of
that series relating to the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to Debt Securities of such
series. 
 None of the provisions of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any personal
financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if there shall be reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or
liability is not reasonably assured to it. 
 Regardless of whether expressly so provided herein, every provision of this Indenture relating
to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 
 Section 7.02. Certain Rights of Trustee. Except as otherwise provided in Section 7.01: 
 (a) the Trustee may rely and
shall be protected in acting or refraining from acting upon any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note or other paper or document (whether in its original or
facsimile form) believed by it to be genuine and to have been signed or presented by the proper party or parties; 
 (b) any request,
direction, order or demand of the Partnership mentioned herein shall be sufficiently evidenced by a Partnership Order (unless other evidence in respect thereof be herein specifically prescribed); and any resolution of the Board of Directors may be
evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the General Partner; 
 (c) the Trustee
may consult with counsel, and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any 

  

 38 

 
action taken or suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel; 
 (d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of
any of the Holders of Debt Securities of any series pursuant to the provisions of this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be
incurred therein or thereby; 
 (e) the Trustee shall not be liable for any action taken or omitted by it in good faith and reasonably
believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; 
 (f) prior to the
occurrence of an Event of Default and after the curing of all Events of Default which may have occurred, the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, approval or other paper or document, unless requested in writing to do so by the Holders of a majority in aggregate principal amount of the then Outstanding Debt Securities of a series
affected by such matter; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making of such investigation is not, in the opinion of the
Trustee, reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such costs, expenses or liabilities as a condition to so proceeding, and the reasonable
expense of every such investigation shall be paid by the Partnership or, if paid by the Trustee, shall be repaid by the Partnership upon demand; 
 (g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any misconduct or negligence on the part of
any agent or attorney appointed by it with due care hereunder; and 
 (h) if any property other than cash shall at any time be subject to a
lien in favor of the Holders, the Trustee, if and to the extent authorized by a receivership or bankruptcy court of competent jurisdiction or by the supplemental instrument subjecting such property to such lien, shall be entitled to make advances
for the purpose of preserving such property or of discharging tax liens or other prior liens or encumbrances thereon. 
 Section 7.03.
Trustee Not Liable for Recitals in Indenture or in Debt Securities. The recitals contained herein and in the Debt Securities (except the Trustee’s certificate of authentication) shall be taken as the statements of the Partnership, and
the Trustee assumes no responsibility for the correctness of the same. The Trustee makes no representations as to the validity or sufficiency of this Indenture or of the Debt Securities of any series, except that the Trustee represents that it is
duly authorized to execute and deliver this Indenture, authenticate the Debt Securities and perform its obligations hereunder, and that the statements made by it or to be made by it in a Statement of Eligibility and Qualification on Form T-1
supplied to the Partnership are true and accurate. The Trustee shall not be accountable for the use or application by the Partnership of any of the Debt Securities or of the proceeds thereof. 
  

 39 

 Section 7.04. Trustee, Paying Agent or Registrar May Own Debt Securities. The Trustee or any
Paying Agent or Registrar, in its individual or any other capacity, may become the owner or pledgee of Debt Securities and, subject to the provisions of the TIA relating to conflicts of interest and preferential claims, may otherwise deal with the
Partnership with the same rights it would have if it were not Trustee, Paying Agent or Registrar. 
 Section 7.05. Moneys Received by
Trustee to Be Held in Trust. Subject to the provisions of Section 11.05, all moneys received by the Trustee shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be
segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on any moneys received by it hereunder. So long as no Event of Default shall have occurred and be continuing, all interest allowed
on any such moneys shall be paid from time to time to the Partnership upon a Partnership Order. 
 Section 7.06. Compensation and
Reimbursement. The Partnership and each Guarantor (if any) jointly and severally covenant and agree to pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for all services rendered by it hereunder
(which shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust), and, except as otherwise expressly provided herein, the Partnership or any Guarantor will pay or reimburse the Trustee upon its
request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents,
attorneys and counsel and of all Persons not regularly in its employ), including without limitation, Section 6.02, except any such expense, disbursement or advances as may arise from its negligence, willful misconduct or bad faith. The
Partnership and each Guarantor (if any) also jointly and severally covenant to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without negligence, willful misconduct or bad faith on the part of the
Trustee, arising out of or in connection with the acceptance or administration of this trust or trusts hereunder, including the reasonable costs and expenses of defending itself against any claim of liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligations of the Partnership and each Guarantor (if any) under this Section 7.06 to compensate and indemnify the Trustee and to pay or reimburse the Trustee for expenses, disbursements
and advances shall constitute additional Debt hereunder and shall survive the satisfaction and discharge of this Indenture. The Partnership, each Guarantor (if any) and the Holders agree that such additional Debt shall be secured by a lien prior to
that of the Debt Securities upon all property and funds held or collected by the Trustee, as such, except funds held in trust for the payment of principal of, and premium, if any, or interest on, particular Debt Securities. 
 When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(e) or (f) occurs, the expenses and the
compensation for the services are intended to constitute expenses of administration under any bankruptcy, insolvency, reorganization or other similar law. 
 Section 7.07. Right of Trustee to Rely on an Officers’ Certificate Where No Other Evidence Specifically Prescribed. Except as otherwise provided in Section 7.01, whenever in the administration of the
provisions of this Indenture the Trustee shall deem it necessary or desirable 

  

 40 

 
that a matter be proved or established prior to taking or suffering or omitting any action hereunder, such matter (unless other evidence in respect thereof
be herein specifically prescribed) may, in the absence of negligence or bad faith on the part of the Trustee, be deemed to be conclusively proved and established by an Officers’ Certificate delivered to the Trustee. Such certificate, in the
absence of negligence or bad faith on the part of the Trustee, shall be full warrant to the Trustee for any action taken, suffered or omitted by it under the provisions of this Indenture upon the faith thereof. 
 Section 7.08. Separate Trustee; Replacement of Trustee. The Partnership may, but need not, appoint a separate Trustee for any one or more series
of Debt Securities. The Trustee may resign with respect to one or more or all series of Debt Securities at any time by giving notice to the Partnership and each Guarantor with respect to such series. The Holders of a majority in principal amount of
the Debt Securities of a particular series may remove the Trustee for such series and only such series by so notifying the Trustee and may appoint a successor Trustee. The Partnership shall remove the Trustee if: 
 (a) the Trustee fails to comply with Section 7.10; 
 (b) the Trustee is adjudged bankrupt or insolvent; 
 (c) a Custodian takes charge of the Trustee or its
property; or 
 (d) the Trustee otherwise becomes incapable of acting in such capacity. 
 If the Trustee resigns, is removed by the Partnership or by the Holders of a majority in principal amount of the Debt Securities of a particular series and such Holders
do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such event being referred to herein as the retiring Trustee), the Partnership shall promptly appoint a successor
Trustee. No resignation or removal of the Trustee and no appointment of a successor Trustee shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of this Section 7.08.

 A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Partnership and each
Guarantor (if any). Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall mail a
notice of its succession to Holders of Debt Securities of each applicable series. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee, subject to the lien provided for in Section 7.06.

 If a successor Trustee does not take office within 60 days after the retiring Trustee gives notice of resignation or is removed, the
retiring Trustee or the Holders of 25% in principal amount of the Debt Securities of any applicable series may petition any court of competent jurisdiction for the appointment of a successor Trustee for the Debt Securities of such series.

 If the Trustee fails to comply with Section 7.10, any Holder of Debt Securities of any applicable series may petition any court of
competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee for the Debt Securities of such series. 
  

 41 

 Notwithstanding the replacement of the Trustee pursuant to this Section 7.08, the obligations of the
Partnership and each Guarantor (if any) under Section 7.06 shall continue for the benefit of the retiring Trustee. 
 In the case of the
appointment hereunder of a separate or successor trustee with respect to the Debt Securities of one or more series, the Partnership, each Guarantor with respect to the Debt Securities of any applicable series (if any), any retiring Trustee and each
successor or separate Trustee with respect to the Debt Securities of any applicable series shall execute and deliver an indenture supplemental hereto (i) which shall contain such provisions as shall be deemed necessary or desirable to confirm
that all the rights, powers, trusts and duties of any retiring Trustee with respect to the Debt Securities of any series as to which any such retiring Trustee is not retiring shall continue to be vested in such retiring Trustee and (ii) that
shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one trustee, it being understood that nothing herein or in such supplemental
indenture shall constitute such Trustees co-trustees of the same trust and that each such separate, retiring or successor Trustee shall be Trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by
any other such Trustee. 
 Section 7.09. Successor Trustee by Merger. If the Trustee consolidates with, merges or converts into, or
transfers all or substantially all its corporate trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor
Trustee. 
 In case at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the
trusts created by this Indenture, any of the Debt Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor trustee, and deliver such Debt Securities
so authenticated; and in case at that time any of the Debt Securities shall not have been authenticated, any successor to the Trustee may authenticate such Debt Securities either in the name of any predecessor hereunder or in the name of the
successor to the Trustee; and in all such cases such certificates shall have the full force afforded anywhere in the Debt Securities or in this Indenture to a certificate of the Trustee. 
 Section 7.10. Eligibility; Disqualification. The Trustee shall at all times satisfy the requirements of Section 310(a) of the TIA. The
Trustee shall have a combined capital and surplus of at least $50,000,000 as set forth in its most recent published annual report of condition. No obligor upon the Debt Securities of a particular series or Person directly or indirectly controlling,
controlled by or under common control with such obligor shall serve as Trustee upon the Debt Securities of such series. The Trustee shall comply with Section 310(b) of the TIA; provided, however, that there shall be excluded from the
operation of Section 310(b)(1) of the TIA this Indenture or any indenture or indentures under which other securities or certificates of interest or participation in other securities of the Partnership or any Guarantor are outstanding if the
requirements for such exclusion set forth in Section 310(b)(1) of the TIA are met. 
  

 42 

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

 Section 7.12. Compliance with Tax Laws. The Trustee hereby agrees to comply with all U.S. Federal income tax information
reporting and withholding requirements applicable to it with respect to payments of premium (if any) and interest on the Debt Securities, whether acting as Trustee, Registrar, Paying Agent or otherwise with respect to the Debt Securities.

 Section 7.13. Administration of Trust. The Trustee shall administer the trust of the Indenture and shall perform a substantial
part of its obligations relating to each series of Debt Securities and this Indenture at its corporate trust office in the City of New York. 
 ARTICLE VIII 
 CONCERNING THE HOLDERS 
 Section 8.01. Evidence of Action by Holders. Whenever in this Indenture it is provided that the Holders of a specified percentage in
aggregate principal amount of the Debt Securities of any or all series may take action (including the making of any demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action), the fact that at the
time of taking any such action the Holders of such specified percentage have joined therein may be evidenced by any instrument or any number of instruments of similar tenor executed by Holders in Person or by agent or proxy appointed in writing, by
the record of the Holders voting in favor thereof at any meeting of Holders duly called and held in accordance with the provisions of Section 5.02 or by a combination of such instrument or instruments and any such record of such a meeting of
Holders. 
 Section 8.02. Proof of Execution of Instruments and of Holding of Debt Securities. Subject to the provisions of
Section 7.01, Section 7.02 and Section 15.09, proof of the execution of any instrument by a Holder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and regulations as may be prescribed by the
Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Debt Securities of any series shall be proved by the Debt Security Register or by a certificate of the Registrar for such series. The Trustee may require such
additional proof of any matter referred to in this Section 8.02 as it shall deem necessary. 
 Section 8.03. Who May Be Deemed
Owner of Debt Securities. Prior to due presentment for registration of transfer of any Debt Security, the Partnership, the Trustee, any Paying Agent and any Registrar may deem and treat the Person in whose name any Debt Security shall be
registered upon the books of the Partnership as the absolute owner of such Debt Security (whether or not such Debt Security shall be overdue and notwithstanding any notation of ownership or other writing thereon) for the purpose of receiving payment
of or on account of the principal of and premium, if any, and (subject to Section 2.12) interest on such Debt Security and for all other purposes, and neither the Partnership nor the Trustee nor any Paying Agent nor any Registrar shall be
affected by any notice to the contrary; and all such payments so made to any such Holder for the time being, or upon his order, shall be valid and, to the extent of the sum 

  

 43 

 
or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such Debt Security. 
 None of the Partnership, the Trustee, any agent of the Trustee, any Paying Agent or any Registrar will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial ownership interests in a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests. 
 Section 8.04. Instruments Executed by Holders Bind Future Holders. At any time prior to (but not after) the Trustee receiving evidence, as
provided in Section 8.01, of any action taken by the Holders of the percentage in aggregate principal amount of the Debt Securities of any series specified in this Indenture and subject to the following paragraph, any Holder of a Debt Security
which is shown by the evidence to have consented to such action may, by filing written notice with the Trustee at its corporate trust office and upon proof of holding as provided in Section 8.02, revoke such action so far as concerns such Debt
Security. Except as aforesaid any such action taken by the Holder of any Debt Security shall be conclusive and binding upon such Holder and upon all future Holders and owners of such Debt Security and of any Debt Security issued upon transfer
thereof or in exchange or substitution therefor, irrespective of whether or not any notation in regard thereto is made upon such Debt Security or such other Debt Securities. Any action taken by the Holders of the percentage in aggregate principal
amount of the Debt Securities of any series specified in this Indenture in connection with such action shall be conclusively binding upon the Partnership, the Trustee and the Holders of all the Debt Securities of such series. 
 The Partnership may, but shall not be obligated to, fix a record date for the purpose of determining the Holders of Debt Securities entitled to give
their consent or take any other action required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders of Debt Securities at such
record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be Holders of Debt
Securities after such record date. No such consent shall be valid or effective for more than 120 days after such record date unless the consent of the Holders of the percentage in aggregate principal amount of the Debt Securities of such series
specified in this Indenture shall have been received within such 120-day period. 
 ARTICLE IX 
 SUPPLEMENTAL INDENTURES 
 Section 9.01. Purposes for Which Supplemental Indenture May Be Entered into Without Consent of Holders. The Partnership, when authorized by resolutions of the Board of Directors, each Guarantor (if any) and the Trustee may from
time to time and at any time, without the consent of Holders, enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the TIA as in force at the date of the execution thereof) for one or more of the
following purposes: 
 (a) to evidence the succession pursuant to Article X of another Person to the Partnership or any Guarantor, or
successive successions, and the assumption by the Successor Partnership or any Successor Guarantor (in each case, as defined in Section 10.01) of the covenants, agreements and obligations of the Partnership or any Guarantor, respectively, in
this Indenture and in the Debt Securities; 
  

 44 

 (b) to surrender any right or power herein conferred upon the Partnership or any Guarantor, to add to the
covenants of the Partnership or any Guarantor such further covenants, restrictions, conditions or provisions for the protection of the Holders of all or any series of Debt Securities (and if such covenants are to be for the benefit of less than all
series of Debt Securities, stating that such covenants are expressly being included solely for the benefit of such series) as the Board of Directors shall consider to be for the protection of the Holders of such Debt Securities, and to make the
occurrence, or the occurrence and continuance, of a Default in any of such additional covenants, restrictions, conditions or provisions a Default or an Event of Default permitting the enforcement of all or any of the several remedies provided in
this Indenture; provided that, in respect of any such additional covenant, restriction, condition or provision, such supplemental indenture may provide for a particular period of grace after Default (which period may be shorter or longer than
that allowed in the case of other Defaults) or may provide for an immediate enforcement upon such Default or may limit the remedies available to the Trustee upon such Default or may limit the right of the Holders of a majority in aggregate principal
amount of any or all series of Debt Securities to waive such default; 
 (c) to cure any ambiguity or omission or to correct or supplement
any provision contained herein, in any supplemental indenture or in any Debt Securities of any series that may be defective or inconsistent with any other provision contained herein, in any supplemental indenture or in the Debt Securities of such
series; 
 (d) to convey, transfer, assign, mortgage or pledge any property to or with the Trustee, or to make such other provisions in
regard to matters or questions arising under this Indenture, as shall not adversely affect the interests of any Holders of Debt Securities of any series; 
 (e) to modify or amend this Indenture in such a manner as to permit the qualification of this Indenture or any indenture supplemental hereto under the TIA as then in effect, except that nothing herein contained shall
permit or authorize the inclusion in any indenture supplemental hereto of the provisions referred to in Section 316(a)(2) of the TIA; 
 (f) to add to or change any of the provisions of this Indenture to change or eliminate any restrictions on the payment of principal of, or premium, if any, on, Debt Securities; provided that any such action shall not adversely affect
the interests of the Holders of Debt Securities of any series in any material respect or permit or facilitate the issuance of Debt Securities of any series in uncertificated form; 
 (g) to secure any or all of the Debt Securities; 
 (h) to make any change in Article XIII that would limit or terminate the benefits available to any holder of Senior Indebtedness (or Representatives therefor) under Article XIII; 

  

 45 

 
provided, however, that an amendment under this Section 9.01 may not make any change that adversely affects the rights under Article XIII of
any holder of Senior Indebtedness then outstanding, unless the holders of the requisite percentage of such Senior Indebtedness (or any group or Representative thereof authorized to give a consent) consent to such change, as provided in the
agreements under which such Senior Indebtedness is outstanding; 
 (i) to make any change that does not adversely affect the rights of any
Holder; 
 (j) to add to, change or eliminate any of the provisions of this Indenture in respect of one or more series of Debt Securities;
provided, however, that any such addition, change or elimination not otherwise permitted under this Section 9.01 shall neither apply to any Debt Security of any series created prior to the execution of such supplemental indenture and
entitled to the benefit of such provision nor modify the rights of the Holder of any such Debt Security with respect to such provision or shall become effective only when there is no such Debt Security Outstanding; 
 (k) to evidence and provide for the acceptance of appointment hereunder by a successor or separate Trustee with respect to the Debt Securities of one or
more series and to add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee; 
 (l) to establish the form or terms of Debt Securities of any series as permitted by Section 2.01 and Section 2.03; and 
 (m) to reflect the release of any Guarantor of its obligations under the Guarantee, in the manner provided by this Indenture. 
 The Trustee is hereby authorized to join with the Partnership and each Guarantor (if any) in the execution of any such supplemental indenture, to make
any further appropriate agreements and stipulations which may be therein contained and to accept the conveyance, transfer, assignment, mortgage or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such
supplemental indenture which affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Any
supplemental indenture authorized by the provisions of this Section 9.01 may be executed by the Partnership, each Guarantor (if any) and the Trustee without the consent of the Holders of any of the Debt Securities at the time Outstanding,
notwithstanding any of the provisions of Section 9.02. 
 Section 9.02. Modification of Indenture with Consent of Holders of
Debt Securities. Without notice to any Holder but with the consent (evidenced as provided in Section 8.01) of the Holders of not less than a majority in aggregate principal amount of the Outstanding Debt Securities of each series affected
by such supplemental indenture (including consents obtained in connection with a tender offer or exchange offer for any such series of Debt Securities), the Partnership, when authorized by resolutions of the Board of Directors, each Guarantor (if
any) and the Trustee may from time to time and at any time enter into an indenture or indentures supplemental hereto (which shall conform to the provisions of the TIA as in force at the date of execution thereof) for the purpose of adding any
provisions to or changing in any manner or 

  

 46 

 
eliminating any of the provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the Holders of the Debt
Securities of such series; provided that, no such supplemental indenture, without the consent of the Holders of each Debt Security so affected, shall: reduce the percentage in principal amount of Debt Securities of any series whose Holders
must consent to an amendment; reduce the rate of or extend the time for payment of interest on any Debt Security; reduce the principal of or extend the Stated Maturity of any Debt Security; reduce the premium payable upon the redemption of any Debt
Security or change the time at which any Debt Security may or shall be redeemed in accordance with Article III; make any Debt Security payable in currency other than the Dollar; impair the right of any Holder to receive payment of premium, if
any, principal of and interest on such Holder’s Debt Securities on or after the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Debt Securities; release any security that may
have been granted in respect of the Debt Securities; or make any change in Section 6.06 or this Section 9.02. 
 A supplemental
indenture which changes or eliminates any covenant or other provision of this Indenture which has been expressly included solely for the benefit of one or more particular series of Debt Securities or which modifies the rights of the Holders of Debt
Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Debt Securities of any other series. 
 Upon the request of the Partnership, accompanied by a copy of resolutions of the Board of Directors authorizing the execution of any such supplemental
indenture, and upon the filing with the Trustee of evidence of the consent of Holders as aforesaid, the Trustee shall join with the Partnership and each Guarantor (if any) in the execution of such supplemental indenture unless such supplemental
indenture affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion but shall not be obligated to enter into such supplemental indenture. 
 It shall not be necessary for the consent of the Holders under this Section 9.02 to approve the particular form of any proposed supplemental
indenture, but it shall be sufficient if such consent shall approve the substance thereof. 
 An amendment under this Section 9.02 may
not make any change that adversely affects the rights under Article XIII of any holder of Senior Indebtedness then outstanding, unless the holders of the requisite percentage of such Senior Indebtedness (or any group or Representative thereof
authorized to give a consent) consent to such change, as provided in the agreements under which such Senior Indebtedness is outstanding. 
 After an amendment under this Section 9.02 becomes effective, the Partnership shall mail to Holders of Debt Securities of each series affected thereby a notice briefly describing such amendment. The failure to give such notice to all
such Holders, or any defect therein, shall not impair or affect the validity of an amendment under this Section 9.02. 
 Section 9.03. Effect of Supplemental Indentures. Upon the execution of any supplemental indenture pursuant to the provisions of this Article IX, this Indenture shall be and be deemed to be modified and amended in accordance
therewith and the respective rights, limitations of rights, obligations, duties and immunities under this Indenture of the Trustee, the 

  

 47 

 
Partnership, each Guarantor (if any) and the Holders shall thereafter be determined, exercised and enforced hereunder subject in all respects to such
modifications and amendments, and all the terms and conditions of any such supplemental indenture shall be and be deemed to be part of the terms and conditions of this Indenture for any and all purposes. 
 The Trustee, subject to the provisions of Section 7.01 and Section 7.02, may receive an Officers’ Certificate and an Opinion of Counsel as
conclusive evidence that any such supplemental indenture complies with the provisions of this Article IX. 
 Section 9.04. Debt
Securities May Bear Notation of Changes by Supplemental Indentures. Debt Securities of any series authenticated and delivered after the execution of any supplemental indenture pursuant to the provisions of this Article IX may, and shall if
required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. New Debt Securities of any series so modified as to conform, in the opinion of the Trustee and the Board of
Directors, to any modification of this Indenture contained in any such supplemental indenture may be prepared and executed by the Partnership, authenticated by the Trustee and delivered in exchange for the Debt Securities of such series then
Outstanding. Failure to make the appropriate notation or to issue a new Debt Security of such series shall not affect the validity of such amendment. 
 ARTICLE X 
 CONSOLIDATION, MERGER, SALE OR CONVEYANCE 
 Section 10.01. Consolidations and Mergers of the Partnership or any Guarantor. Neither the Partnership nor any Guarantor shall consolidate or
amalgamate with or merge with or into any Person, or sell, convey, transfer, lease or otherwise dispose of all or substantially all its assets to any Person, whether in a single transaction or a series of related transactions, (1) except in
accordance with the provisions of the partnership agreement, certificate or articles of incorporation, bylaws or other applicable organizational documents thereof, and (2) unless: (a) either (i) the Partnership or such Guarantor (as
the case may be) shall be the continuing Person in the case of a merger or (ii) the resulting, surviving or transferee Person if other than the Partnership or such Guarantor (respectively, the “Successor Partnership” and the
“Successor Guarantor”), shall be a partnership, limited liability company or corporation organized and existing under the laws of the United States of America, any state thereof or the District of Columbia, or Canada or any province
thereof, and the Successor Partnership or Successor Guarantor (as the case may be) shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form satisfactory to the Trustee, all the obligations of the
Partnership or such Guarantor (as applicable) under this Indenture and the Debt Securities or the applicable Guarantee according to their tenor; (b) immediately after giving effect to such transaction (and treating any Debt which becomes an
obligation of the Successor Partnership or the Successor Guarantor (as the case may be) or any Subsidiary thereof as a result of such transaction as having been incurred by the Successor Partnership or the Successor Guarantor (as applicable) or such
Subsidiary at the time of such transaction), no Default or Event of Default would occur or be continuing; and (c) the Partnership shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that
such consolidation, amalgamation, merger or disposition and such supplemental indenture (if any) comply with this Indenture. 
  

 48 

 Section 10.02. Rights and Duties of Successor Partnership and Successor Guarantor. In case of
any consolidation, amalgamation or merger where the Partnership or any Guarantor is not the continuing Person, or disposition of all or substantially all of the assets of the Partnership or any Guarantor in accordance with Section 10.01, the
Successor Partnership or Successor Guarantor (as the case may be) shall succeed to and be substituted for the Partnership or such Guarantor (as applicable) with the same effect as if it had been named herein as the respective party to this
Indenture, and the predecessor entity shall be released from all liabilities and obligations under this Indenture, the Debt Securities and any Guarantee, except that no such release will occur in the case of a lease of all or substantially all of
its assets. 
 The Successor Partnership thereupon may cause to be signed, and may issue either in its own name or in the name of the
Partnership, any or all the Debt Securities issuable hereunder which theretofore shall not have been signed by the Partnership and delivered to the Trustee; and, upon the order of the Successor Partnership, instead of the Partnership, and subject to
all the terms, conditions and limitations in this Indenture prescribed, the Trustee shall authenticate and shall deliver any Debt Securities which previously shall have been signed and delivered by the Officers of the General Partner to the Trustee
for authentication, and any Debt Securities which the Successor Partnership thereafter shall cause to be signed and delivered to the Trustee for that purpose. All the Debt Securities so issued shall in all respects have the same legal rank and
benefit under this Indenture as the Debt Securities theretofore or thereafter issued in accordance with the terms of this Indenture as though all such Debt Securities had been issued at the date of the execution hereof. 
 In case of any such consolidation, amalgamation, merger, sale or disposition such changes in phraseology and form (but not in substance) may be made in
the Debt Securities thereafter to be issued as may be appropriate. 
 ARTICLE XI  
 SATISFACTION AND DISCHARGE OF 
 INDENTURE; DEFEASANCE; UNCLAIMED MONEYS 
 Section 11.01. Applicability of Article. The provisions of this
Article XI relating to defeasance of Debt Securities shall be applicable to each series of Debt Securities except as otherwise specified pursuant to Section 2.03 for Debt Securities of such series. 
 Section 11.02. Satisfaction and Discharge of Indenture; Defeasance. 
 (a) If at any time the Partnership shall have delivered to the Trustee for cancellation all Debt Securities of any series theretofore authenticated and
delivered (other than any Debt Securities of such series which shall have been destroyed, lost or stolen and which shall have been replaced or paid as provided in Section 2.09 and Debt Securities for whose payment money has theretofore been
deposited in trust and thereafter repaid to the Partnership as provided in Section 11.05) or all Debt Securities of such series not theretofore delivered to the Trustee for cancellation shall have become due and payable, or are by their terms
to become due and payable within one year or are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice of redemption, and the Partnership or any Guarantor shall deposit with the Trustee
as trust funds the entire amount in cash sufficient to pay 

  

 49 

 
at maturity or upon redemption all Debt Securities of such series not theretofore delivered to the Trustee for cancellation, including principal and premium,
if any, and interest due or to become due on such date of Stated Maturity or redemption date, as the case may be, and if in either case the Partnership or any Guarantor shall also pay or cause to be paid all other sums payable hereunder by the
Partnership and/or the Guarantors (if any), then this Indenture shall cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of such Debt Securities herein expressly provided for) with respect to the
Debt Securities of such series, and the Trustee, on demand of the Partnership accompanied by an Officers’ Certificate and an Opinion of Counsel and at the cost and expense of the Partnership, shall execute proper instruments acknowledging
satisfaction of and discharging this Indenture. 
 (b) Subject to Section 11.02(c), Section 11.03 and Section 11.07, the
Partnership at any time may terminate, with respect to Debt Securities of a particular series, (i) all of the obligations of the Partnership and each Guarantor (if any) under the Debt Securities of such series and this Indenture with respect to
the Debt Securities of such series (“legal defeasance option”) or (ii) the operation of (x) Section 4.07, Section 4.08 and Section 4.09 and Article X and any covenant made applicable to such Debt Securities
pursuant to Section 2.03 and (y) Section 6.01(d), (g), (h) and (i) (“covenant defeasance option”). The Partnership may exercise its legal defeasance option notwithstanding its prior exercise of its covenant
defeasance option. 
 If the Partnership exercises its legal defeasance option, payment of the Debt Securities of the defeased series may not
be accelerated because of an Event of Default. If the Partnership exercises its covenant defeasance option, payment of the Debt Securities of the defeased series may not be accelerated because of an Event of Default specified in
Section 6.01(d), (g), (h) or (i) (except to the extent covenants or agreements referenced in such Sections remain applicable). 
 Upon satisfaction of the conditions set forth herein and upon request of the Partnership, the Trustee shall acknowledge in writing the discharge of those obligations that the Partnership terminates. 
 (c) Notwithstanding clauses (a) and (b) above, the Partnership’s obligations in Section 2.07, Section 2.09, Section 4.01,
Section 4.02, Section 4.03, Section 4.04, Section 4.05, Section 4.06, Section 5.01, Section 7.06, Section 11.05, Section 11.06 and Section 11.07 shall survive until the Debt Securities of the
defeased series have been paid in full. Thereafter, the Partnership’s obligations in Section 7.06, Section 11.05 and Section 11.06 shall survive. 
 Section 11.03. Conditions of Defeasance. The Partnership may exercise its legal defeasance option or its covenant defeasance option with respect to Debt Securities of a particular series only if:

 (a) the Partnership or any Guarantor irrevocably deposits in trust with the Trustee money or U.S. Government Obligations for the payment
of principal of, and premium, if any, and interest on, the Debt Securities of such series to Stated Maturity or redemption, as the case may be; 
 (b) the Partnership delivers to the Trustee a certificate from a nationally recognized firm of independent accountants expressing their opinion that the payments of principal and 

  

 50 

 
interest when due and without reinvestment on the deposited U.S. Government Obligations plus any deposited money without investment will provide cash at such
times and in such amounts as will be sufficient to pay the principal, premium and interest when due on all the Debt Securities of such series to Stated Maturity or redemption, as the case may be; 
 (c) 91 days pass after the deposit is made and during the 91-day period no Default specified in Section 6.01(e) or (f) with respect to the
Partnership or any Guarantor occurs which is continuing at the end of the period; 
 (d) no Default has occurred and is continuing on the
date of such deposit and after giving effect thereto; 
 (e) the deposit does not constitute a default under any other agreement binding on
the Partnership or any Guarantor and is not prohibited by Article XIII; 
 (f) the Partnership delivers to the Trustee an Opinion of
Counsel to the effect that the trust resulting from the deposit does not constitute, or is qualified as, a regulated investment company under the Investment Company Act of 1940; 
 (g) in the event of an exercise of the legal defeasance option, the Partnership shall have delivered to the Trustee an Opinion of Counsel stating that
the Partnership has received from the Internal Revenue Service a ruling, or since the date of this Indenture there has been a change in the applicable Federal income tax law, in either case of the effect that, and based thereon such Opinion of
Counsel shall confirm that, the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a result of such defeasance and will be subject to Federal income tax on the same amounts, in the
same manner and at the same times as would have been the case if such defeasance had not occurred; 
 (h) in the event of an exercise of the
covenant defeasance option, the Partnership shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of Debt Securities of such series will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance had not occurred; and 
 (i) the Partnership delivers to the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent to the
defeasance and discharge of the Debt Securities of such series as contemplated by this Article XI have been complied with. 
 Before or
after a deposit, the Partnership may make arrangements satisfactory to the Trustee for the redemption of Debt Securities of such series at a future date in accordance with Article III. 
 Section 11.04. Application of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations deposited with it pursuant to
this Article XI. It shall apply the deposited money and the money from U.S. Government Obligations through any Paying Agent and in accordance with this Indenture to the payment of principal of, and premium, if any, and 

  

 51 

 
interest on, the Debt Securities of the defeased series. Money and securities so held in trust shall not be subject to the provisions of Article XIII.

 Section 11.05. Repayment to Partnership. The Trustee and any Paying Agent shall promptly turn over to the Partnership upon
request any excess money or securities held by them at any time. 
 Subject to any applicable abandoned property law, the Trustee and any
Paying Agent shall pay to the Partnership upon request any money held by them for the payment of principal, premium or interest that remains unclaimed for two years, and, thereafter, Holders entitled to such money must look to the Partnership for
payment as general creditors. 
 Section 11.06. Indemnity for U.S. Government Obligations. The Partnership and each Guarantor (if
any), jointly and severally, shall pay and shall indemnify the Trustee and the Holders against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S.
Government Obligations. 
 Section 11.07. Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or U.S.
Government Obligations in accordance with this Article XI by reason of any legal proceeding or by reason of any order or judgment of any court or government authority enjoining, restraining or otherwise prohibiting such application, the
Partnership’s and each Guarantor’s obligations under this Indenture and the Debt Securities of the defeased series (or the Guarantees related thereto) shall be revived and reinstated as though no deposit had occurred pursuant to this
Article XI until such time as the Trustee or any Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article XI. 
 ARTICLE XII 
 GUARANTEE OF DEBT SECURITIES 
 Section 12.01. Unconditional Guarantee. 
 (a) For value received, each of the Guarantors hereby fully, irrevocably, unconditionally and absolutely guarantees to the Holders of Debt Securities of each series to which this Article XII has been made applicable as provided in
Section 2.03(t) and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on such Debt Securities, and all other amounts due and payable under this Indenture and such Debt Securities by the
Partnership to the Trustee or such Holders (including, without limitation, all costs and expenses (including reasonable legal fees and disbursements) incurred by the Trustee or such Holders in connection with the enforcement of this Indenture and
the Guarantee) (collectively, the “Indenture Obligations”), when and as such amounts shall become due and payable, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, according to the terms of
such Debt Securities and this Indenture. The guarantees by the Guarantors set forth in this Article XII are referred to herein as the “Guarantee.” Without limiting the generality of the foregoing, each Guarantor’s liability shall
extend to all amounts that constitute part of the Indenture Obligations and would be owed by the Partnership to the Trustee or such Holders under this Indenture and such Debt Securities but for the fact that they are unenforceable, 

  

 52 

 
reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Partnership.

 (b) Failing payment when due of any amount guaranteed pursuant to the Guarantee, for whatever reason, each Guarantor will be obligated (to
the fullest extent permitted by applicable law) to pay the same immediately to the Trustee, without set-off or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise). The Guarantee hereunder is intended to be a
general, unsecured, senior obligation of each Guarantor and will rank pari passu in right of payment with all unsecured indebtedness of such Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantee of
such Guarantor. Each Guarantor hereby agrees that, to the fullest extent permitted by applicable law, its obligations hereunder shall be full, irrevocable, unconditional and absolute, irrespective of the validity, regularity or enforceability of
such Debt Securities, the Guarantee or this Indenture, the absence of any action to enforce the same, any waiver or consent by any such Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Partnership,
any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of such Guarantor. Each Guarantor hereby agrees that in the event of a default in payment of any Indenture
Obligations, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of such Holders or, subject to Section 6.04 hereof, by such Holders, on
the terms and conditions set forth in this Indenture, directly against such Guarantor to enforce the Guarantee without first proceeding against the Partnership. 
 (c) To the fullest extent permitted by applicable law, the obligations of each Guarantor under this Article XII shall be as aforesaid full, irrevocable, unconditional and absolute and shall not be impaired,
modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the
obligations and liabilities of the Partnership or any Guarantor contained in any of such Debt Securities or this Indenture, (ii) any impairment, modification, release or limitation of the liability of the Partnership, any Guarantor or any of
their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, as amended, or other statute or from the decision of any court, (iii) the
assertion or exercise by the Trustee or any such Holder of any rights or remedies under any of such Debt Securities or this Indenture or their delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the
purported assignment of any property as security for any of such Debt Securities, including all or any part of the rights of the Partnership or any Guarantor under this Indenture, (v) the extension of the time for payment by the Partnership or
any Guarantor of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of such Debt Securities or this Indenture or of the time for performance by the Partnership or any Guarantor of any other
obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation of the Partnership or any
Guarantor set forth in this Indenture, (vii) 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, rehabilitation 

  

 53 

 
or relief of, or other similar proceeding affecting, the Partnership or any Guarantor or any of their respective assets, or the disaffirmance of any of such
Debt Securities, the Guarantee or this Indenture in any such proceeding, (viii) the release or discharge of the Partnership or any Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of
such instruments by operation of law, (ix) the unenforceability of any of such Debt Securities, the Guarantee or this Indenture, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Partnership
or any Guarantor, or (xi) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or any Guarantor. 
 (d) To the fullest extent permitted by applicable law, each Guarantor hereby (i) waives diligence, presentment, demand of payment, notice of
acceptance, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Partnership or such Guarantor, and all demands and notices whatsoever, (ii) acknowledges that any agreement, instrument or document evidencing
the Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantee without notice to them and (iii) covenants that its Guarantee will
not be discharged except by complete performance of the Guarantee. To the fullest extent permitted by applicable law, each Guarantor further agrees that if at any time all or any part of any payment theretofore applied by any Person to any Guarantee
is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of any Guarantor, such Guarantee shall, to the extent that such payment is or must be rescinded or returned,
be deemed to have continued in existence notwithstanding such application, and the Guarantee shall continue to be effective or be reinstated, as the case may be, as though such application had not been made. 
 (e) Each Guarantor shall be subrogated to all rights of the Holders and the Trustee against the Partnership in respect of any amounts paid by such
Guarantor pursuant to the provisions of this Indenture; provided, however, that such Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation with respect to any of
such Debt Securities until all of such Debt Securities and the Guarantee shall have been indefeasibly paid in full or discharged. 
 (f) No
partner, director, officer, employee or equity holder, as such, of a Guarantor shall have any liability for any obligations of the Guarantor under this Indenture or for any claim based on, in respect of or by reason of such obligations or their
creation. 
 (g) To the fullest extent permitted by applicable law, no failure to exercise and no delay in exercising, on the part of the
Trustee or the Holders, any right, power, privilege or remedy under this Article XII and the Guarantee shall operate as a waiver thereof, nor shall any single or partial exercise of any rights, power, privilege or remedy preclude any other or
further exercise thereof, or the exercise of any other rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative and not exclusive of any rights or remedies provided in law or equity. Nothing contained in
this Article XII shall limit the right of the Trustee or the Holders to take any action to accelerate the maturity of such Debt Securities pursuant to Article VI or to pursue any rights or remedies hereunder or under applicable law.

  

 54 

 Section 12.02. Limitation on Guarantor Liability. Each Guarantor, and, by its acceptance of
Debt Securities, each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act,
the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of
such Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections
from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under this Article XII, result in the obligations of such Guarantor under its Guarantee not
constituting a fraudulent transfer or conveyance. 
 Section 12.03. Execution and Delivery of Notation of Guarantee. 

To further evidence the Guarantee, each Guarantor hereby agrees that a notation of such Guarantee may be endorsed on each Debt Security of a series to
which this Article XII has been made applicable authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer of such Guarantor. 
 Each Guarantor hereby agrees that its Guarantee of Debt Securities of a series to which this Article XII has been made applicable shall remain in
full force and effect notwithstanding any failure to endorse on any such Debt Security a notation relating to the Guarantee thereof. 
 If an
officer of any Guarantor whose signature is on this Indenture or a Debt Security no longer holds that office at the time the Trustee authenticates such Debt Security or at any time thereafter, such Guarantor’s Guarantee of such Debt Security
shall be valid nevertheless. 
 The delivery by the Trustee of any Debt Security of a series to which this Article XII has been made
applicable, after the authentication thereof under this Indenture, shall constitute due delivery of the Guarantee set forth in this Indenture on behalf of each Guarantor. 
 Section 12.04. Release of Guarantee. 
 (a) Notwithstanding anything to the contrary in this
Article XII, if any Guarantor shall cease to be either (i) a Subsidiary of the Partnership or (ii) an obligor on any Funded Debt other than the Debt Securities, then if no Default or Event of Default shall have occurred and be
continuing, such Guarantor, upon giving notice to the Trustee to the foregoing effect, shall be deemed to be released from all of its obligations under this Indenture and the Guarantee shall be of no further force or effect with respect to such
Guarantor. Following the receipt by the Trustee of any such notice, the Partnership shall cause this Indenture to be amended as provided in Section 9.01(l) hereof; provided, however, that the failure to so amend this Indenture
shall not affect the validity of the termination of the Guarantee with respect to such Guarantor. 
 (b) In addition, upon the exercise of
the legal defeasance option or the satisfaction and discharge of this Indenture as provided in Section 11.02 hereof, each of the Guarantors shall be deemed to be released from all its obligations under this Indenture and the Guarantee shall be
of no further force or effect. 
  

 55 

 ARTICLE XIII 
 SUBORDINATION OF DEBT SECURITIES 
 Section 13.01. Applicability of Article; Agreement
To Subordinate. The provisions of this Article XIII shall be applicable to all the Debt Securities of any series issued under this Indenture. Each Holder by accepting a Debt Security agrees that the Debt evidenced by such Debt Security is
subordinated in right of payment, to the extent and in the manner provided in this Article XIII, to the prior payment of all Senior Indebtedness and that the subordination is for the benefit of and enforceable by the holders of Senior
Indebtedness. All provisions of this Article XIII shall be subject to Section 13.12. 
 Section 13.02. Liquidation,
Dissolution, Bankruptcy. Upon any payment or distribution of the assets of the Partnership to creditors, upon a liquidation or a dissolution of the Partnership or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding
relating to the Partnership or its property: 
 (a) holders of Senior Indebtedness of the Partnership shall be entitled to receive payment in
full in cash of such Senior Indebtedness (including interest (if any), accruing on or after the commencement of a proceeding in bankruptcy, whether or not allowed as a claim against the Partnership in such bankruptcy proceeding) before Holders of
Debt Securities shall be entitled to receive any payment of principal of, or premium, if any, or interest on, the Debt Securities from the Partnership; and 
 (b) until the Senior Indebtedness of the Partnership is paid in full, any distribution to which Holders of Debt Securities would be entitled but for this Article XIII shall be made to holders of Senior
Indebtedness of the Partnership as their interests may appear, except that such Holders may receive capital stock and any debt securities that are subordinated to Senior Indebtedness of the Partnership to at least the same extent as the Debt
Securities of the Partnership. 
 Section 13.03. Default on Senior Indebtedness. The Partnership may not pay the principal of, or
premium, if any, or interest on, the Debt Securities or make any deposit pursuant to Article XI and may not repurchase, redeem or otherwise retire (except, in the case of Debt Securities that provide for a mandatory sinking fund pursuant to
Section 3.05, by the delivery of Debt Securities by the Partnership to the Trustee pursuant to the first paragraph of Section 3.05) any Debt Securities if any principal, premium or interest in respect of Senior Indebtedness of such Person
is not paid within any applicable grace period (including at maturity) or any other default on Senior Indebtedness of such Person occurs and the maturity of such Senior Indebtedness is accelerated in accordance with its terms unless, in either case,
the default has been cured or waived and any such acceleration has been rescinded or such Senior Indebtedness has been paid in full in cash; provided, however, that the Partnership may make payments on the Debt Securities without regard to
the foregoing if the Partnership and the Trustee receive written notice approving such payment from the Representative of each issue of Designated Senior Indebtedness. During the continuance of any other default with respect to any Designated Senior
Indebtedness pursuant to which the maturity thereof may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, the Partnership may not
make payments on the Debt 

  

 56 

 
Securities for a period (a “Payment Blockage Period”) commencing upon the receipt by the Partnership and the Trustee of written notice of such
default from the Representative of any Designated Senior Indebtedness specifying an election to effect a Payment Blockage Period (a “Blockage Notice”) and ending 179 days thereafter (or earlier if such Payment Blockage Period is terminated
by written notice to the Trustee and the Partnership from the Person or Persons who gave such Blockage Notice, by repayment in full in cash of such Designated Senior Indebtedness or because the default giving rise to such Blockage Notice is no
longer continuing). Notwithstanding the provisions described in the immediately preceding sentence (but subject to the provisions contained in Section 13.02 and the first sentence of this Section 13.03), unless the holders of such
Designated Senior Indebtedness or the Representative of such holders shall have accelerated the maturity of such Designated Senior Indebtedness, the Partnership may resume payments on the Debt Securities after such Payment Blockage Period. Not more
than one Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to any number of issues of Designated Senior Indebtedness during such period, unless otherwise specified pursuant to
Section 2.03 for the Debt Securities of a series; provided, however, that in no event may the total number of days during which any Payment Blockage Period or Periods is in effect exceed 179 days in the aggregate during any 360
consecutive day period. For purposes of this Section 13.03, no default or event of default which existed or was continuing on the date of the commencement of any Payment Blockage Period with respect to the Designated Senior Indebtedness
initiating such Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Payment Blockage Period by the Representative of such Designated Senior Indebtedness, whether or not within a period of 360 consecutive days,
unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 
 Section 13.04. Acceleration of Payment of Debt Securities. If payment of the Debt Securities is accelerated because of an Event of Default, the Partnership shall promptly notify the holders of the Designated Senior Indebtedness
(or their Representatives) of the acceleration. 
 Section 13.05. When Distribution Must Be Paid Over. If a distribution is made
to Holders of Debt Securities that because of this Article XIII should not have been made to them, the Holders who receive such distribution shall hold it in trust for holders of Senior Indebtedness and pay it over to them as their interests
may appear. 
 Section 13.06. Subrogation. After all Senior Indebtedness is paid in full and until the Debt Securities are paid
in full, Holders of Debt Securities shall be subrogated to the rights of holders of Senior Indebtedness to receive distributions applicable to Senior Indebtedness. A distribution made under this Article XIII to holders of Senior Indebtedness
which otherwise would have been made to Holders of Debt Securities is not, as between the Partnership and such Holders, a payment by the Partnership on Senior Indebtedness. 
 Section 13.07. Relative Rights. This Article XIII defines the relative rights of Holders of Debt Securities and holders of Senior
Indebtedness. Nothing in this Indenture shall: 
 (a) impair, as between the Partnership and Holders of Debt Securities, the obligation of the
Partnership, which is absolute and unconditional, to pay principal of, and premium, if any, and interest on, the Debt Securities in accordance with their terms; or 
  

 57 

 (b) prevent the Trustee or any Holder of Debt Securities from exercising its available remedies upon an
Event of Default, subject to the rights of holders of Senior Indebtedness to receive distributions otherwise payable to Holders of Debt Securities. 
 Section 13.08. Subordination May Not Be Impaired by Partnership. No right of any holder of Senior Indebtedness to enforce the subordination of the Debt evidenced by the Debt Securities shall be impaired by any act or failure to
act by the Partnership or by its failure to comply with this Indenture. 
 Section 13.09. Rights of Trustee and Paying Agent.
Notwithstanding Section 13.02 and Section 13.03, the Trustee or any Paying Agent may continue to make payments on Debt Securities and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such
payments unless, not less than two Business Days prior to the date of such payment, a responsible officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article XIII. The Partnership, the Registrar,
any Paying Agent, a Representative or a holder of Senior Indebtedness may give the notice; provided, however, that, if an issue of Senior Indebtedness has a Representative, only the Representative may give the notice on behalf of the holders
of the Senior Indebtedness of that issue. 
 The Trustee in its individual or any other capacity may hold Senior Indebtedness with the same
rights it would have if it were not Trustee. The Registrar and any Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article XIII with respect to any Senior Indebtedness which may
at any time be held by it, to the same extent as any other holder of Senior Indebtedness; and nothing in Article VII shall deprive the Trustee of any of its rights as such holder. Nothing in this Article XIII shall apply to claims of, or
payments to, the Trustee under or pursuant to Section 7.06. 
 Section 13.10. Distribution or Notice to Representative.
Whenever a distribution is to be made or a notice given to holders of Senior Indebtedness, the distribution may be made and the notice given to their Representative (if any). 
 Section 13.11. Article XIII Not to Prevent Defaults or Limit Right to Accelerate. The failure to make a payment pursuant to the Debt
Securities by reason of any provision in this Article XIII shall not be construed as preventing the occurrence of a Default or Event of Default. Nothing in this Article XIII shall have any effect on the right of the Holders or the Trustee
to accelerate the maturity of the Debt Securities. 
 Section 13.12. Trust Moneys Not Subordinated. Notwithstanding anything
contained herein to the contrary, payments from money or the proceeds of U.S. Government Obligations held in trust under Article XI by the Trustee for the payment of principal of, and premium, if any, and interest on, the Debt Securities shall
not be subordinated to the prior payment of any Senior Indebtedness or subject to the restrictions set forth in this Article XIII, and none of the Holders thereof shall be obligated to pay over any such amount to the Partnership or any holder
of Senior Indebtedness of the Partnership or any other creditor of the Partnership. 
 Section 13.13. Trustee Entitled to Rely.
Upon any payment or distribution pursuant to this Article XIII, the Trustee and the Holders shall be entitled to rely upon any order or decree of 

  

 58 

 
a court of competent jurisdiction in which any proceedings of the nature referred to in Section 13.02 are pending, upon a certificate of the liquidating
trustee or agent or other Person making such payment or distribution to the Trustee or to such Holders or upon the Representatives for the holders of Senior Indebtedness for the purpose of ascertaining the Persons entitled to participate in such
payment or distribution, the holders of the Senior Indebtedness and other Debt of the Partnership, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this
Article XIII. In the event that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Senior Indebtedness to participate in any payment or distribution pursuant to this
Article XIII, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Senior Indebtedness held by such Person, the extent to which such Person is entitled to participate in such
payment or distribution and other facts pertinent to the rights of such Person under this Article XIII, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of
such Person to receive such payment. The provisions of Section 7.01 and Section 7.02 shall be applicable to all actions or omissions of actions by the Trustee pursuant to this Article XIII. 
 Section 13.14. Trustee to Effectuate Subordination. Each Holder by accepting a Debt Security authorizes and directs the Trustee on his behalf
to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders of Debt Securities and the holders of Senior Indebtedness as provided in this Article XIII and appoints the Trustee as
attorney-in-fact for any and all such purposes. 
 Section 13.15. Trustee Not Fiduciary for Holders of Senior Indebtedness. The
Trustee shall not be deemed to owe any fiduciary duty to the holders of Senior Indebtedness and shall not be liable to any such holders if it shall mistakenly pay over or distribute to Holders of Debt Securities, the Partnership or any other Person
money or assets to which any holders of Senior Indebtedness shall be entitled by virtue of this Article XIII or otherwise. 
 Section 13.16. Reliance by Holders of Senior Indebtedness on Subordination Provisions. Each Holder by accepting a Debt Security acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an
inducement and a consideration to each holder of any Senior Indebtedness, whether such Senior Indebtedness was created or acquired before or after the issuance of the Debt Securities, to acquire and continue to hold, or to continue to hold, such
Senior Indebtedness and such holder of Senior Indebtedness shall be deemed conclusively to have relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Senior Indebtedness. 
 ARTICLE XIV 
 SUBORDINATION
OF GUARANTEES 
 Section 14.01. Applicability of Article; Agreement To Subordinate. The provisions of this
Article XIV shall be applicable to all Guarantees of any series of Debt Securities issued under this Indenture. Each Holder by accepting a Guarantee agrees that the obligations evidenced by such Guarantee are subordinated in right of payment,
to the extent and in the manner provided in this Article XIV, to the prior payment of all Guarantor Senior Indebtedness 

  

 59 

 
and that the subordination is for the benefit of and enforceable by the holders of Guarantor Senior Indebtedness. All provisions of this Article XIV
shall be subject to Section 14.12. 
 Section 14.02. Liquidation, Dissolution, Bankruptcy. Upon any payment or distribution
of the assets of any Guarantor to creditors, upon a liquidation or a dissolution of any Guarantor or in a bankruptcy, reorganization, insolvency, receivership or similar proceeding relating to any Guarantor or its property: 
 (a) holders of any Guarantor Senior Indebtedness of such Guarantor shall be entitled to receive payment in full in cash of such Guarantor Senior
Indebtedness (including interest (if any), accruing on or after the commencement of a proceeding in bankruptcy, whether or not allowed as a claim against such Guarantor in such bankruptcy proceeding) before Holders of Guarantees shall be entitled to
receive any payment in respect of such Guarantees from such Guarantor; and 
 (b) until the Guarantor Senior Indebtedness of such Guarantor
is paid in full, any distribution to which Holders of Guarantees would be entitled but for this Article XIV shall be made to holders of such Guarantor Senior Indebtedness as their interests may appear, except that such Holders may receive
capital stock and any debt securities that are subordinated to such Guarantor Senior Indebtedness to at least the same extent as the Guarantees of such Guarantor. 
 Section 14.03. Default on Guarantor Senior Indebtedness. A Guarantor may not make any payment in respect of its Guarantees or make any deposit pursuant to Article XI and may not repurchase, redeem or
otherwise retire any Guarantees if any principal, premium or interest in respect of Guarantor Senior Indebtedness of such Guarantor is not paid within any applicable grace period (including at maturity) or any other default on Guarantor Senior
Indebtedness of such Guarantor occurs and the maturity of such Guarantor Senior Indebtedness is accelerated in accordance with its terms unless, in either case, the default has been cured or waived and any such acceleration has been rescinded or
such Guarantor Senior Indebtedness has been paid in full in cash; provided, however, that a Guarantor may make payments in respect of its Guarantees without regard to the foregoing if such Guarantor and the Trustee receive written notice
approving such payment from the Representative of each issue of Designated Guarantor Senior Indebtedness. During the continuance of any other default with respect to any Designated Guarantor Senior Indebtedness pursuant to which the maturity thereof
may be accelerated immediately without further notice (except such notice as may be required to effect such acceleration) or the expiration of any applicable grace periods, a Guarantor may not make payments in respect of its Guarantees for a period
(a “Guarantee Payment Blockage Period”) commencing upon the receipt by the Guarantor and the Trustee of written notice of such default from the Representative of any Designated Guarantor Senior Indebtedness specifying an election to effect
a Guarantee Payment Blockage Period (a “Guarantee Blockage Notice”) and ending 179 days thereafter (or earlier if such Guarantee Payment Blockage Period is terminated by written notice to the Trustee and the Guarantor from the Person or
Persons who gave such Guarantee Blockage Notice, by repayment in full in cash of such Designated Guarantor Senior Indebtedness or because the default giving rise to such Guarantee Blockage Notice is no longer continuing). Notwithstanding the
provisions described in the immediately preceding sentence (but subject to the provisions contained in Section 14.02 and the first sentence of this Section 14.03), unless the holders of such Designated Guarantor Senior Indebtedness or the
Representative of such holders 

  

 60 

 
shall have accelerated the maturity of such Designated Guarantor Senior Indebtedness, the Guarantor may resume payments in respect of its Guarantees after
such Guarantee Payment Blockage Period. Not more than one Guarantee Blockage Notice may be given in any consecutive 360-day period, irrespective of the number of defaults with respect to any number of issues of Designated Guarantor Senior
Indebtedness during such period, unless otherwise specified pursuant to Section 2.03 for the Debt Securities of a series; provided, however, that in no event may the total number of days during which any Guarantee Payment Blockage Period
or Periods is in effect exceed 179 days in the aggregate during any 360 consecutive day period. For purposes of this Section 14.03, no default or event of default which existed or was continuing on the date of the commencement of any Guarantee
Payment Blockage Period with respect to the Designated Senior Indebtedness initiating such Guarantee Payment Blockage Period shall be, or be made, the basis of the commencement of a subsequent Guarantee Payment Blockage Period by the Representative
of such Designated Guarantor Senior Indebtedness, whether or not within a period of 360 consecutive days, unless such default or event of default shall have been cured or waived for a period of not less than 90 consecutive days. 
 Section 14.04. Acceleration of Payment of Debt Securities. If payment of the Debt Securities is accelerated because of an Event of Default,
each Guarantor shall promptly notify the holders of the Designated Guarantor Senior Indebtedness of such Guarantor (or their Representatives) of the acceleration. 
 Section 14.05. When Distribution Must Be Paid Over. If a distribution is made to Holders of Guarantees that because of this Article XIV should not have been made to them, the Holders who receive such
distribution shall hold it in trust for holders of Guarantor Senior Indebtedness and pay it over to them as their interests may appear. 
 Section 14.06. Subrogation. After all Guarantor Senior Indebtedness is paid in full and until all obligations arising under the Guarantees are satisfied in full, Holders of Guarantees shall be subrogated to the rights of holders
of Guarantor Senior Indebtedness to receive distributions applicable to Guarantor Senior Indebtedness. A distribution made under this Article XIV to holders of Guarantor Senior Indebtedness which otherwise would have been made to Holders of
Guarantees is not, as between any Guarantor and such Holders, a payment by such Guarantor on Guarantor Senior Indebtedness. 
 Section 14.07. Relative Rights. This Article XIV defines the relative rights of Holders of Guarantees and holders of Guarantor Senior Indebtedness. Nothing in this Indenture shall: 
 (a) impair, as between any Guarantor and Holders of Guarantees, the obligation of such Guarantor, which is absolute and unconditional, to make payments
in respect of the Guarantees in accordance with their terms; or 
 (b) prevent the Trustee or any Holder of Guarantees from exercising its
available remedies upon an Event of Default, subject to the rights of holders of Guarantor Senior Indebtedness to receive distributions otherwise payable to Holders of Guarantees. 
 Section 14.08. Subordination May Not Be Impaired by Guarantor. No right of any holder of Guarantor Senior Indebtedness to enforce the
subordination of the obligations evidenced by 

  

 61 

 
the Guarantees shall be impaired by any act or failure to act by any Guarantor or by its failure to comply with this Indenture. 
 Section 14.09. Rights of Trustee and Paying Agent. Notwithstanding Section 14.02 and Section 14.03, the Trustee or any Paying Agent
may continue to make payments in respect of Guarantees and shall not be charged with knowledge of the existence of facts that would prohibit the making of any such payments unless, not less than two Business Days prior to the date of such payment, a
responsible officer of the Trustee receives notice satisfactory to it that payments may not be made under this Article XIV. Any Guarantor, the Registrar, any Paying Agent, a Representative or a holder of Guarantor Senior Indebtedness may give
the notice; provided, however, that, if an issue of Guarantor Senior Indebtedness has a Representative, only the Representative may give the notice on behalf of the holders of the Guarantor Senior Indebtedness of that issue. 
 The Trustee in its individual or any other capacity may hold Guarantor Senior Indebtedness with the same rights it would have if it were not Trustee. The
Registrar and any Paying Agent may do the same with like rights. The Trustee shall be entitled to all the rights set forth in this Article XIV with respect to any Guarantor Senior Indebtedness which may at any time be held by it, to the same
extent as any other holder of Guarantor Senior Indebtedness; and nothing in Article VII shall deprive the Trustee of any of its rights as such holder. Nothing in this Article XIV shall apply to claims of, or payments to, the Trustee under
or pursuant to Section 7.06. 
 Section 14.10. Distribution or Notice to Representative. Whenever a distribution is to be
made or a notice given to holders of Guarantor Senior Indebtedness, the distribution may be made and the notice given to their Representative (if any). 
 Section 14.11. Article XIV Not to Prevent Defaults or Limit Right to Accelerate. The failure to fulfill any obligation arising under any Guarantee by reason of any provision in this Article XIV
shall not be construed as preventing the occurrence of a Default or Event of Default. Nothing in this Article XIV shall have any effect on the right of the Holders or the Trustee to accelerate the maturity of the Debt Securities. 
 Section 14.12. Trustee Entitled to Rely. Upon any payment or distribution pursuant to this Article XIV, the Trustee and the Holders
shall be entitled to rely upon any order or decree of a court of competent jurisdiction in which any proceedings of the nature referred to in Section 14.02 are pending, upon a certificate of the liquidating trustee or agent or other Person
making such payment or distribution to the Trustee or to such Holders or upon the Representatives for the holders of Guarantor Senior Indebtedness for the purpose of ascertaining the Persons entitled to participate in such payment or distribution,
the holders of Guarantor Senior Indebtedness and other Debt of such Guarantor, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XIV. In the event
that the Trustee determines, in good faith, that evidence is required with respect to the right of any Person as a holder of Guarantor Senior Indebtedness to participate in any payment or distribution pursuant to this Article XIV, the Trustee
may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of Guarantor Senior Indebtedness held by such Person, the extent to which such Person is entitled 

  

 62 

 
to participate in such payment or distribution and other facts pertinent to the rights of such Person under this Article XIV, and, if such evidence is
not furnished, the Trustee may defer any payment to such Person pending judicial determination as to the right of such Person to receive such payment. The provisions of Section 7.01 and Section 7.02 shall be applicable to all actions or
omissions of actions by the Trustee pursuant to this Article XIV. 
 Section 14.13. Trustee to Effectuate Subordination.
Each Holder by accepting a Guarantee authorizes and directs the Trustee on his behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination between the Holders of Guarantees and the holders of
Guarantor Senior Indebtedness as provided in this Article XIV and appoints the Trustee as attorney-in-fact for any and all such purposes. 
 Section 14.14. Trustee Not Fiduciary for Holders of Guarantor Senior Indebtedness. The Trustee shall not be deemed to owe any fiduciary duty to the holders of Guarantor Senior Indebtedness and shall not be liable to any such
holders if it shall mistakenly pay over or distribute to Holders of Guarantees, any Guarantor or any other Person money or assets to which any holders of Guarantor Senior Indebtedness shall be entitled by virtue of this Article XIV or
otherwise. 
 Section 14.15. Reliance by Holders of Guarantor Senior Indebtedness on Subordination Provisions. Each Holder by
accepting a Guarantee acknowledges and agrees that the foregoing subordination provisions are, and are intended to be, an inducement and a consideration to each holder of any Guarantor Senior Indebtedness, whether such Guarantor Senior Indebtedness
was created or acquired before or after the issuance of the Guarantees, to acquire and continue to hold, or to continue to hold, such Guarantor Senior Indebtedness and such holder of Guarantor Senior Indebtedness shall be deemed conclusively to have
relied on such subordination provisions in acquiring and continuing to hold, or in continuing to hold, such Guarantor Senior Indebtedness. 
 ARTICLE XV

Debt Securities or any Guarantee that may be instituted in the Supreme Court of the State of New York or the United States District Court for the Southern District of New York, in either case in the Borough of Manhattan, The City of New York, by the
Trustee or the Holder of any Debt Security, and to the fullest extent permitted by applicable law, each of the Partnership and such Guarantor hereby waives any objection which it may now or hereafter have to the laying of venue of any such
proceeding and expressly and irrevocably accepts and submits, for the benefit of the Trustee and the Holders from time to time of the Debt Securities, to the nonexclusive 

  

 66 

 
jurisdiction of any such court in respect of any such action, suit or proceeding, for itself and with respect to its properties, revenues and assets. Once
made, such appointment shall be irrevocable unless and until the Partnership or such Guarantor has appointed a successor Authorized Agent for such purpose, and such successor’s acceptance of such appointment shall have occurred. Each of the
Partnership and such Guarantor agrees to take any and all actions, including the filing of any and all documents and instruments, that may be necessary so that once made such appointment shall continue in full force and effect as aforesaid. Service
of process upon the Authorized Agent with respect to any such action shall be deemed, in every respect, effective service of process upon the Partnership or such Guarantor, as the case may be. 
 Section 15.15. Judgment Currency. Each of the Partnership and any Guarantor agrees to indemnify each of the Trustee and the Holders against
any loss incurred by it as a result of any judgment or order being given or made with respect to the Debt Securities, any Guarantee or this Indenture and expressed and paid in a currency (the “Judgment Currency”) other than U.S. dollars
and as a result of any variation as between (i) the rate of exchange at which the U.S. dollar amount is converted into the Judgment Currency for the purpose of such judgment or order and (ii) the spot rate of exchange in The City of New
York at which the Trustee or such Holder on the date of payment of such judgment or order is able to purchase U.S. dollars with the amount of the Judgment Currency actually received by the Trustee or such Holder. The foregoing indemnity shall
constitute a separate and independent obligation of each of the Partnership and any Guarantor and shall continue in full force and effect notwithstanding any such judgment or order as aforesaid. The term “spot rate of exchange” shall
include any premium and cost of exchange payable in connection with the purchase of, or conversion into, U.S. dollars.

provided, further, that if the Borrower shall fail to give any required notice as described above in this paragraph or if such continuation is not permitted pursuant to the preceding proviso, such Loans shall be converted automatically to Base Rate
Loans on the last day of such then expiring Interest Period. Upon receipt of any such notice the Administrative Agent shall promptly notify each relevant Lender thereof. 
 Section 2.12 Minimum Amounts and Maximum Number of Eurodollar Tranches. Notwithstanding anything to the contrary in this Agreement, all borrowings, conversions, continuations and optional prepayments of
Eurodollar Loans and all selections of Interest Periods shall be in such amounts and be made pursuant to such elections so that, (a) after giving effect thereto, the aggregate principal amount of the Eurodollar Loans comprising each Eurodollar
Tranche shall be equal to $1,000,000 or a whole multiple of $1,000,000 in excess thereof (or, if the then aggregate Available Revolving Credit Commitments are less than $1,000,000, such lesser amount) and (b) no more than five Eurodollar
Tranches for each Facility shall be outstanding at any one time. 
 Section 2.13 Interest Rates and Payment Dates. 
 (a) Each Eurodollar Loan shall bear interest for each day during each Interest Period with respect thereto at a rate per annum equal to
the Eurodollar Rate determined for such Interest Period plus the Applicable Margin in effect for such day. For avoidance of doubt, it is understood that interest payable on a Eurodollar Loan for any Interest Period shall accrue from and including
the first day of such Interest Period to but excluding the last day of such Interest Period. 
 (b) Each Base Rate Loan shall
bear interest for each day on which it is outstanding at a rate per annum equal to the Base Rate in effect for such day plus the Applicable Margin in effect for such day. 
 (c) Upon the occurrence and during the continuance of any Event of Default, at the election of either the Administrative Agent or the
Required Lenders, all amounts payable under this Agreement (to the extent legally permitted) shall bear interest at a rate per annum that is equal to (x) in the case of the Loans, the rate that would otherwise be applicable thereto pursuant to
the foregoing provisions of this Section plus 2% or (y) in 

  

 30 

 
the case of Reimbursement Obligations, the rate applicable to Base Rate Loans under the Revolving Credit Facility plus 2% (or, in the case of any such other
amounts that do not relate to a particular Facility, the rate then applicable to Base Rate Loans under the Revolving Credit Facility plus 2%), in each case, from the date of such Event of Default until such amount is paid in full (after as well as
before judgment). 
 (d) Interest shall be payable in arrears on each Interest Payment Date, provided that interest accruing
pursuant to paragraph (c) of this Section shall be payable from time to time on demand. 
 Section 2.14 Computation of
Interest and Fees. 
 (a) Interest, fees and commissions payable pursuant hereto shall be calculated on the basis of a
360-day year for the actual days elapsed. The Administrative Agent shall as soon as practicable notify the Borrower and the relevant Lenders of each determination of a Eurodollar Rate. Any change in the interest rate on a Loan resulting from a
change in the Base Rate or the Eurocurrency Reserve Requirements shall become effective as of the opening of business on the day on which such change becomes effective. The Administrative Agent shall as soon as practicable notify the Borrower and
the relevant Lenders of the effective date and the amount of each such change in interest rate. 
 (b) Each determination of
an interest rate by the Administrative Agent pursuant to any provision of this Agreement shall be conclusive and binding on the Borrower and the Lenders in the absence of manifest error. The Administrative Agent shall, at the request of the
Borrower, deliver to the Borrower a statement showing the quotations used by the Administrative Agent in determining any interest rate pursuant to Section 2.14(a). 
 Section 2.15 Inability to Determine Interest Rate. If prior to the first day of any Interest Period: 
 (a) the Administrative Agent shall have determined (which determination shall be conclusive and binding upon the Borrower) that, by reason
of circumstances affecting the relevant market, adequate and reasonable means do not exist for ascertaining the Eurodollar Rate for such Interest Period, or 
 (b) the Administrative Agent shall have received notice from the Majority Facility Lenders in respect of the relevant Facility that the
Eurodollar Rate determined or to be determined for such Interest Period will not adequately and fairly reflect the cost to such Lenders (as conclusively certified by such Lenders) of making or maintaining their affected Loans during such Interest
Period, 
 the Administrative Agent shall give telecopy or telephonic notice thereof to the Borrower and the relevant Lenders as soon as
practicable thereafter. If such notice is given (x) any Eurodollar Loans under the relevant Facility requested to be made on the first day of such Interest Period shall be made as Base Rate Loans, (y) any Loans under the relevant Facility
that were to have been converted on the first day of such Interest Period to 

  

 31 

 
Eurodollar Loans shall be continued as Base Rate Loans and (z) any outstanding Eurodollar Loans under the relevant Facility shall be converted, on the
last day of the then current Interest Period with respect thereto, to Base Rate Loans. Until such notice has been withdrawn by the Administrative Agent, no further Eurodollar Loans under the relevant Facility shall be made or continued as such, nor
shall the Borrower have the right to convert Loans under the relevant Facility to Eurodollar Loans. 
 Section 2.16 Pro Rata Treatment and
Payments. 
 (a) Each borrowing by the Borrower from the Lenders hereunder, each payment by the Borrower on account of any
commitment fee or Letter of Credit Accommodation fee, and any reduction of the Commitments of the Lenders, shall be made pro rata according to the respective Term Loan Percentages or Revolving Credit Percentages, as the case may be, of the relevant
Lenders. 
 (b) Each payment (including each prepayment) of the Term Loans shall be allocated among the Term Loan Lenders
holding such Term Loans pro rata based on the principal amount of such Term Loans held by such Term Loan Lenders, and shall be applied to the installments of such Term Loans pro rata based on the remaining outstanding principal amount of such
installments. Amounts prepaid on account of the Term Loans may not be reborrowed. 
 (c) Each payment (including each
prepayment) by the Borrower on account of principal of and interest on the Revolving Credit Loans shall be made pro rata according to the respective outstanding principal amounts of the Revolving Credit Loans then held by the Revolving Credit
Lenders. Each payment in respect of Reimbursement Obligations in respect of any Letter of Credit Accommodation shall be made as provided in Section 3.01. 
 (d) The application of any payment of Loans under any Facility (including optional and mandatory prepayments) shall be made, first, to
Base Rate Loans under such Facility and, second, to Eurodollar Loans under such Facility. Each payment of the Loans (except in the case of Revolving Credit Loans that are Base Rate Loans) shall be accompanied by accrued interest to the date of such
payment on the amount paid. Except as otherwise expressly provided in this Agreement: 
 (i) Upon the occurrence and during
the continuance of an Event of Default, Borrower irrevocably waives the right to direct the application of any and all payments at any time or times received by Administrative Agent from or on behalf of Borrower or any Loan Party of all or any part
of the Obligations in accordance to Section 2.16(d)(iii) below, and Administrative Agent shall have the continuing and exclusive right to apply and to reapply any and all such payments received at any time or times against the Obligations in
such manner as Administrative Agent may deem advisable notwithstanding any previous application by Administrative Agent or the Lenders; 
  

 32 

 (ii) so long as no Event of Default exists, the proceeds of any sale of, or other
realization upon, all or any part of the Collateral and all payments and distributions made by any Loan Party with respect to the Obligations, shall be applied: first, to all fees, costs, indemnities and expenses incurred by or owing to
Administrative Agent, with respect to this Agreement, the other Loan Documents or the Collateral; second, to all fees, costs, indemnities and expenses incurred by or owing to any Lender with respect to this Agreement, the other Loan
Documents, or the Collateral; third, to accrued and unpaid interest on the Revolving Credit Loans; fourth, to reduce the principal amount of the Revolving Credit Loans; fifth, to accrued and unpaid interest on the Term Loans;
sixth, to principal installments due on the Term Loans in inverse order of maturity; and seventh, to any other indebtedness or obligations of Borrower or other Loan Party owing to Administrative Agent, any Lender or any Qualified
Counterparty under the Loan Documents or with respect to any Specified Hedge Agreements, including without limitation fees, costs, indemnities and expenses thereunder; and 
 (iii) following the occurrence and during the continuance of an Event of Default, all payments and proceeds of Collateral shall be
applied: first, to all fees, costs, indemnities and expenses incurred by or owing to Administrative Agent, with respect to this Agreement, the other Loan Documents or the Collateral; second, to all fees, costs, indemnities and expenses
incurred by or owing to any Lender with respect to this Agreement, the other Loan Documents, or the Collateral; third, to accrued and unpaid interest on the Revolving Credit Loans (including any interest which but for the provisions of the
Bankruptcy Code, would have accrued on such amounts); fourth, to the outstanding principal balance of the Revolving Credit Loans (including cash collateralizing any Letter of Credit Accommodations) until the same have been paid in full (and
all Letter of Credit Accommodations have been cash collateralized in the amount of 105% thereof); fifth, to accrued and unpaid interest on the Term Loans; sixth, to principal installments due on the Term Loans in inverse order of
maturity; and seventh, to any other indebtedness or obligations of Borrower or other Loan Party owing to Administrative Agent, any Lender or any Qualified Counterparty under the Loan Documents or with respect to any Specified Hedge
Agreements, including without limitation fees, costs, indemnities and expenses thereunder. Any balance remaining shall be delivered to whomever may be lawfully entitled to receive such balance or as a court of competent jurisdiction may direct.

 (e) All payments (including prepayments) to be made by the Borrower hereunder, whether on account of principal, interest,
fees or otherwise, shall be made without setoff or counterclaim and shall be made prior to 2 P.M., New York City time, on the due date thereof to the Administrative Agent, for the account of the relevant Lenders, at the Payment Office, in Dollars
and in immediately available funds. Any payment made by the Borrower after 2:00 P.M., New York City time, on any Business Day shall be deemed to have been on the next following Business Day. The Administrative Agent shall distribute such payments to
the Lenders promptly upon receipt in like funds as received. If any payment hereunder (other than payments on the Eurodollar Loans) becomes due and payable on a day other than a Business Day, such payment shall be extended to the next succeeding
Business Day. If any payment on a Eurodollar Loan becomes due and payable on a day other than a Business Day, the maturity thereof shall be extended to the next succeeding Business Day unless the result of such extension would be to extend such
payment into another calendar month, in which event such 

  

 33 

 
payment shall be made on the immediately preceding Business Day. In the case of any extension of any payment of principal pursuant to the preceding two
sentences, interest thereon shall be payable at the then applicable rate during such extension. 
 (f) Unless the
Administrative Agent shall have been notified in writing by any Lender prior to a borrowing that such Lender will not make the amount that would constitute its share of such borrowing available to the Administrative Agent, the Administrative Agent
may assume that such Lender is making such amount available to the Administrative Agent, and the Administrative Agent may, in reliance upon such assumption, make available to the Borrower a corresponding amount. If such amount is not made available
to the Administrative Agent by the required time on the Borrowing Date therefor, such Lender shall pay to the Administrative Agent, on demand, such amount with interest thereon at a rate equal to the daily average Federal Funds Effective Rate for
the period until such Lender makes such amount immediately available to the Administrative Agent. A certificate of the Administrative Agent submitted to any Lender with respect to any amounts owing under this paragraph shall be conclusive in the
absence of manifest error. If such Lender’s share of such borrowing is not made available to the Administrative Agent by such Lender within three Business Days after such Borrowing Date, the Administrative Agent shall also be entitled to
recover such amount with interest thereon at the rate per annum applicable to Base Rate Loans under the relevant Facility, on demand, from the Borrower. 
 (g) Unless the Administrative Agent shall have been notified in writing by the Borrower prior to the date of any payment due to be made by the Borrower hereunder that the Borrower will not make such payment to the
Administrative Agent, the Administrative Agent may assume that the Borrower is making such payment, and the Administrative Agent may, but shall not be required to, in reliance upon such assumption, make available to the Lenders their respective pro
rata shares of a corresponding amount. If such payment is not made to the Administrative Agent by the Borrower within three Business Days after such due date, the Administrative Agent shall be entitled to recover, on demand, from each Lender to
which any amount which was made available pursuant to the preceding sentence, such amount with interest thereon at the rate per annum equal to the daily average Federal Funds Effective Rate. Nothing herein shall be deemed to limit the rights of the
Administrative Agent or any Lender against the Borrower. 
 Section 2.17 Requirements of Law. 
 (a) If the adoption of or any change in any Requirement of Law or in the interpretation or application thereof or compliance by any Lender
with any request or directive (whether or not having the force of law) from any central bank or other Governmental Authority made subsequent to the date hereof: 
 (i) shall subject any Lender to any tax of any kind whatsoever with respect to this Agreement, any Letter of Credit Accommodation, any
Application or any Eurodollar Loan made by it, or change the basis of taxation of payments to such Lender in respect thereof (except for Non-Excluded Taxes covered by 

  

 34 

 
Section 2.18 and changes in the rate of tax on the overall net income of such Lender); 
 (ii) shall impose, modify or hold applicable any reserve, special deposit, compulsory loan or similar requirement against assets held by,
deposits or other liabilities in or for the account of, advances, loans or other extensions of credit by, or any other acquisition of funds by, any office of such Lender that is not otherwise included in the determination of the Eurodollar Rate
hereunder; or 
 (iii) shall impose on such Lender any other condition; 
 and the result of any of the foregoing is to increase the cost to such Lender, by an amount which such Lender reasonably deems to be material, of making,
converting into, continuing or maintaining Eurodollar Loans or issuing or participating in Letters of Credit, or to reduce any amount receivable hereunder in respect thereof, then, in any such case, the Borrower shall promptly pay such Lender upon
its demand, any additional amounts necessary to compensate such Lender for such increased cost or reduced amount receivable. If any Lender becomes entitled to claim any additional amounts pursuant to this Section, it shall promptly
notify the Borrower (with a copy to the Administrative Agent) of the event by reason of which it has become so entitled. 
 (b) If any Lender shall have determined that the adoption of or any change in any Requirement of Law regarding capital adequacy or in the interpretation or application thereof or compliance by such Lender or any corporation controlling such
Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any Governmental Authority made subsequent to the date hereof shall have the effect of reducing the rate of return on such Lender’s or
such corporation’s capital as a consequence of its obligations hereunder or under or in respect of any Letter of Credit Accommodation to a level below that which such Lender or such corporation could have achieved but for such adoption, change
or compliance (taking into consideration such Lender’s or such corporation’s policies with respect to capital adequacy) by an amount reasonably deemed by such Lender to be material, then from time to time, after submission by such Lender
to the Borrower (with a copy to the Administrative Agent) of a written request therefor, the Borrower shall pay to such Lender such additional amount or amounts as will compensate such Lender or such corporation for such reduction, provided that the
Borrower shall not be required to compensate a Lender pursuant to this paragraph for any amounts incurred more than three months prior to the date that such Lender notifies the Borrower of such Lender’s intention to claim compensation therefor;
and provided further that, if the circumstances giving rise to such claim have a retroactive effect, then such three-month period shall be extended to include the period of such retroactive effect. 
 (c) A certificate as to any additional amounts payable pursuant to this Section submitted by any Lender to the Borrower
(with a copy to the Administrative Agent) shall be conclusive in the absence of manifest error. The obligations of the Borrower pursuant 

  

 35 

 
to this Section shall survive the termination of this Agreement and the payment of the Loans and all other amounts payable hereunder.

 Section 2.18 Taxes. 
 (a) All payments made by the Borrower under this Agreement shall be made free and clear of, and without deduction or withholding for or on account of, any present or future income, stamp or other taxes, levies,
imposts, duties, charges, fees, deductions or withholdings, now or hereafter imposed, levied, collected, withheld or assessed by any Governmental Authority, excluding net income taxes and franchise taxes (imposed in lieu of net income taxes) imposed
on any Agent or any Lender as a result of a present or former connection between such Agent or such Lender and the jurisdiction of the Governmental Authority imposing such tax or any political subdivision or taxing authority thereof or therein
(other than any such connection arising solely from such Agent’s or such Lender’s having executed, delivered or performed its obligations or received a payment under, or enforced, this Agreement or any other Loan Document). If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or withholdings (“Non-Excluded Taxes”) or any Other Taxes are required to be withheld from any amounts payable to any Agent or any Lender hereunder, the
amounts so payable to such Agent or such Lender shall be increased to the extent necessary to yield to such Agent or such Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any such other amounts payable hereunder at the
rates or in the amounts specified in this Agreement; provided, however, that the Borrower shall not be required to increase any such amounts payable to any Lender with respect to any Non-Excluded Taxes (i) that are attributable to such
Lender’s failure to comply with the requirements of paragraph (d) or (e) of this Section or (ii) that are United States withholding taxes imposed on amounts payable to such Lender at the time such Lender becomes a
party to this Agreement, except to the extent that such Lender’s assignor (if any) was entitled, at the time of assignment, to receive additional amounts from the Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph
(a). 
 (b) In addition, the Borrower shall pay any Other Taxes to the relevant Governmental Authority in accordance
with applicable law. 
 (c) Whenever any Non-Excluded Taxes or Other Taxes are payable by the Borrower, as promptly as
possible thereafter the Borrower shall send to the Administrative Agent for the account of the relevant Agent or Lender, as the case may be, a certified copy of an original official receipt received by the Borrower showing payment thereof. If the
Borrower fails to pay any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing authority or fails to remit to the Administrative Agent the required receipts or other required documentary evidence, the Borrower shall indemnify the
Agents and the Lenders for any incremental taxes, interest or penalties that may become payable by any Agent or any Lender as a result of any such failure. The agreements in this Section shall survive the termination of this Agreement
and the payment of the Loans and all other amounts payable hereunder. 
  

 36 

 (d) Each Lender (or Transferee) that is not a citizen or resident of the United States of
America, a corporation, partnership or other entity created or organized in or under the laws of the United States (or any jurisdiction thereof), or any estate or trust that is subject to federal income taxation regardless of the source of its
income (a “Non-U.S. Lender”) shall deliver to the Borrower and the Administrative Agent (or, in the case of a Participant, to the Lender from which the related participation shall have been purchased) two copies of either
U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI, or, in the case of a Non-U.S. Lender claiming exemption from U.S. federal withholding tax under Section 871(h) or 88l(c) of the Code with respect to payments of
“portfolio interest” a statement substantially in the form of Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors thereto properly completed and duly executed by such Non-U.S. Lender claiming complete
exemption from, or a reduced rate of, U.S. federal withholding tax on all payments by the Borrower under this Agreement and the other Loan Documents. Such forms shall be delivered by each Non-U.S. Lender on or before the date it becomes a party to
this Agreement (or, in the case of any Participant, on or before the date such Participant purchases the related participation). In addition, each Non-U.S. Lender shall deliver such forms promptly upon the obsolescence or invalidity of any form
previously delivered by such Non-U.S. Lender. Each Non-U.S. Lender shall promptly notify the Borrower at any time it determines that it is no longer in a position to provide any previously delivered certificate to the Borrower (or any other form of
certification adopted by the U.S. taxing authorities for such purpose). Notwithstanding any other provision of this paragraph, a Non-U.S. Lender shall not be required to deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver. 
 (e) A Lender that is entitled to an exemption from or reduction of non-U.S. withholding tax under
the law of the jurisdiction in which the Borrower is located, or any treaty to which such jurisdiction is a party, with respect to payments under this Agreement shall deliver to the Borrower (with a copy to the Administrative Agent), at the time or
times prescribed by applicable law or reasonably requested by the Borrower, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate, provided
that such Lender is legally entitled to complete, execute and deliver such documentation and in such Lender’s reasonable judgment such completion, execution or submission would not materially prejudice the legal position of such Lender.

 Section 2.19 Indemnity. The Borrower agrees to indemnify each Lender for, and to hold each Lender harmless from, any loss or
expense (but without duplication of any amounts payable as default interest) that such Lender may sustain or incur as a consequence of (a) default by the Borrower in making a borrowing of, conversion into or continuation of Eurodollar Loans
after the Borrower has given a notice requesting the same in accordance with the provisions of this Agreement, (b) default by the Borrower in making any prepayment of Eurodollar Loans after the Borrower has given a notice thereof in accordance
with the provisions of this Agreement or (c) the making of a prepayment or conversion of Eurodollar Loans on a day that is not the last day of an Interest Period with respect thereto. Such indemnification may include an amount equal to the
excess, if any, of (i) the amount of interest that would have accrued on the amount so prepaid, or not so borrowed, converted or continued, for the period from the date of such 

  

 37 

 
prepayment or of such failure to borrow, convert or continue to the last day of such Interest Period (or, in the case of a failure to borrow, convert or
continue, the Interest Period that would have commenced on the date of such failure) in each case at the applicable rate of interest for such Loans provided for herein (excluding, however, the Applicable Margin included therein, if any) over
(ii) the amount of interest (as reasonably determined by such Lender) that would have accrued to such Lender on such amount by placing such amount on deposit for a comparable period with leading banks in the interbank Eurodollar market. A
certificate as to any amounts payable pursuant to this Section submitted to the Borrower by any Lender shall be conclusive in the absence of manifest error. This covenant shall survive the termination of this Agreement and the payment
of the Loans and all other amounts payable hereunder. 
 Section 2.20 Illegality. Notwithstanding any other provision herein, if the
adoption of or any change in any Requirement of Law or in the interpretation or application thereof shall make it unlawful for any Lender to make or maintain Eurodollar Loans as contemplated by this Agreement, (a) the commitment of such Lender
hereunder to make Eurodollar Loans, continue Eurodollar Loans as such and convert Base Rate Loans to Eurodollar Loans shall forthwith be canceled and (b) such Lender’s Loans then outstanding as Eurodollar Loans, if any, shall be converted
automatically to Base Rate Loans on the respective last days of the then current Interest Periods with respect to such Loans or within such earlier period as required by law. If any such conversion of a Eurodollar Loan occurs on a day which is not
the last day of the then current Interest Period with respect thereto, the Borrower shall pay to such Lender such amounts, if any, as may be required pursuant to Section 2.19. 
 Section 2.21 Change of Lending Office. Each Lender agrees that, upon the occurrence of any event giving rise to the operation of
Section 2.17, 2.18(a) or 2.20 with respect to such Lender, it will, if requested by the Borrower, use reasonable efforts (subject to overall policy considerations of such Lender) to designate another
lending office for any Loans affected by such event with the object of avoiding the consequences of such event; provided that such designation is made on terms that, in the sole judgment of such Lender, cause such Lender and its lending office(s) to
suffer no economic, legal or regulatory disadvantage, and provided, further, that nothing in this Section shall affect or postpone any of the obligations of any Borrower or the rights of any Lender pursuant to
Section 2.17, 2.18(a) or 2.20. 
 SECTION 3. LETTERS OF CREDIT 
 Section 3.01 Letter of Credit Accommodations. 
 (i) Subject to and upon the terms and conditions contained herein, at the written request of Borrower, Administrative Agent agrees, for the ratable risk of each Revolving Credit Lender according to its Revolving
Credit Percentage, to provide or arrange for Letter of Credit Accommodations for the account of Borrower, on behalf of itself or any other Loan Party, containing terms and conditions acceptable to Administrative Agent and the issuer thereof. Any
payments made by or on behalf of Administrative Agent or any Revolving Credit Lender to any issuer thereof and/or related parties in connection with the Letter of Credit Accommodations provided to or for the benefit of Borrower or such other 

  

 38 

 
Loan Party shall constitute additional Revolving Credit Loans to Borrower pursuant to Section 2.04. 
 (ii) In addition to any charges, fees or expenses charged by any bank or issuer in connection with the Letter of Credit Accommodations,
Borrower agrees to pay (A) to Administrative Agent, for its own account, a fronting fee equal to 0.125% per annum, times the aggregate daily amount available to be drawn under any letters of credit issued by Administrative Agent and
constituting Letter of Credit Accommodations and (B) to Administrative Agent, for the benefit of the Revolving Credit Lenders, a letter of credit accommodation fee at a rate equal to the Applicable Margin for Revolving Credit Loans which are
Eurodollar Loans set forth in the Pricing Grid, on the daily outstanding balance of the Letter of Credit Accommodations for the immediately preceding month (or part thereof), payable in arrears on each L/C Fee Payment Date; provided, that
Administrative Agent may, and upon the written direction of the Majority Revolving Credit Facility Lenders shall, require Borrower to pay to Administrative Agent for the benefit of the Revolving Credit Lenders such letter of credit accommodation
fee, at a rate equal to two (2%) percent per annum in excess of the otherwise applicable rate on such daily outstanding balance for the period from and after the date of the occurrence of an Event of Default for so long as such Event of Default
is continuing as determined by Administrative Agent. Such letter of credit accommodation fees shall be calculated on the basis of a three hundred sixty (360) day year and actual days elapsed and the obligation of Borrower to pay such fees shall
survive the termination of this Agreement. 
 (iii) The Borrower shall give Administrative Agent five (5) Business
Days’ prior written notice of its request for the issuance of a Letter of Credit Accommodation. Such notice shall be irrevocable and shall specify the original face amount of the Letter of Credit Accommodation requested, the effective date
(which date shall be a Business Day and in no event shall be a date less than thirty (30) days prior to the Revolving Credit Termination Date) of issuance of such requested Letter of Credit Accommodation, whether such Letter of Credit
Accommodation may be drawn in a single or in partial draws, the date on which such requested Letter of Credit Accommodation is to expire (which date shall be a Business Day and in no event shall such date be any date after the fifth Business Day
preceding the Revolving Credit Termination Date or a date more than 365 days after the effective date of issuance of such Letter of Credit Accommodation without taking into account evergreen or other renewal provisions), the purpose for which such
Letter of Credit Accommodation is to be issued, and the beneficiary of the requested Letter of Credit Accommodation. The Borrower shall attach to such notice the proposed terms of the Letter of Credit Accommodation. 
 (iv) In addition to being subject to the satisfaction of the applicable conditions precedent contained in Section 5
hereof and the other terms and conditions contained herein, no Letter of Credit Accommodations shall be available unless each of the following conditions precedent have been satisfied in 

  

 39 

 
a manner reasonably satisfactory to Administrative Agent: (A) the Borrower shall have delivered to the proposed issuer of such Letter of Credit
Accommodation at such times and in such manner as such proposed issuer may require, an application, in form and substance reasonably satisfactory to such proposed issuer and Administrative Agent, for the issuance of the Letter of Credit
Accommodation and such other documents as may be required pursuant to the terms thereof, and the form and terms of the proposed Letter of Credit Accommodation shall be reasonably satisfactory to Administrative Agent and such proposed issuer,
(B) as of the date of issuance, no order of any Governmental Authority shall purport by its terms to enjoin or restrain commercial banks in the United States generally from issuing letters of credit of the type and in the amount of the proposed
Letter of Credit Accommodation, and no law, rule or regulation applicable to commercial banks in the United States generally and no request or directive (whether or not having the force of law) from any Governmental Authority with jurisdiction over
commercial banks in the United States generally shall prohibit, or request that the proposed issuer of such Letter of Credit Accommodation refrain from, the issuance of letters of credit generally or the issuance of such Letters of Credit
Accommodation; and (C) after giving effect to such Letter of Credit Accommodations, on the date of the proposed issuance of any Letter of Credit Accommodations, the Total Revolving Extensions of Credit of all Lenders shall not exceed the Total
Revolving Credit Commitments, provided that the Total Revolving Extensions of Credit shall not exceed an amount equal to $20,000,000 without the prior written consent of the Required Lenders except that such approval shall not be required at
any time that HFC, its Affiliates, Related Funds or Control Investment Affiliates do not, in the aggregate, constitute the Required Lenders. 
 (v) Except as increased in Administrative Agent’s discretion, with the consent of Majority Revolving Credit Facility Lenders, the amount of all outstanding Letter of Credit Accommodations and all other
commitments and obligations made or incurred by Administrative Agent or any Revolving Credit Lender in connection therewith shall not at any time exceed the L/C Commitment. 
 (vi) Borrower and Guarantors shall indemnify and hold Administrative Agent and Lenders harmless from and against any and all losses,
claims, damages, liabilities, costs and expenses which Administrative Agent or any Lender may suffer or incur in connection with any Letter of Credit Accommodations and any documents, drafts or acceptances relating thereto, including any losses,
claims, damages, liabilities, costs and expenses due to any action taken by any issuer or correspondent with respect to any Letter of Credit Accommodation, except for such losses, claims, damages, liabilities, costs or expenses resulting from the
gross negligence, bad faith or willful misconduct of Administrative Agent or any Lender as determined pursuant to a final non-appealable order of a court of competent jurisdiction. Each Loan Party assumes all risks with respect to the acts or
omissions of the drawer under or beneficiary of any Letter of Credit Accommodation and for such purposes the drawer or beneficiary shall be deemed such Loan Party’s agent. Each Loan Party assumes 

  

 40 

 
all risks for, and agrees to pay, all foreign, federal, state and local taxes, duties and levies relating to any goods subject to any Letter of Credit
Accommodations or any documents, drafts or acceptances thereunder. Each Loan Party hereby releases and holds Administrative Agent and the Lenders harmless from and against any acts, waivers, errors, delays or omissions, whether caused by Borrower,
any Guarantor, by any issuer or correspondent or otherwise with respect to or relating to any Letter of Credit Accommodation, except for such acts, waivers, errors, delays, or omissions resulting from the gross negligence or willful misconduct of
Administrative Agent or any Lender as determined pursuant to a final, non-appealable order of a court of competent jurisdiction. The provisions of this Section 3 shall survive the payment of the Obligations and the termination of
this Agreement. 
 (vii) Each Loan Party hereby irrevocably authorizes and directs any issuer of a Letter of Credit
Accommodation to name such Loan Party as the account party therein and to deliver to Administrative Agent all instruments, documents and other writings and property received by issuer pursuant to the Letter of Credit Accommodations and to accept and
rely upon Administrative Agent’s instructions and agreements with respect to all matters arising in connection with the Letter of Credit Accommodations or the applications therefor. Nothing contained herein shall be deemed or construed to grant
any Loan Party any right or authority to pledge the credit of Administrative Agent or any Revolving Credit Lender in any manner. Administrative Agent and the Revolving Credit Lenders shall have no liability of any kind with respect to any Letter of
Credit Accommodation provided by an issuer other than Administrative Agent or any Revolving Credit Lender unless Administrative Agent has duly executed and delivered to such issuer the application or a guarantee or indemnification in writing with
respect to such Letter of Credit Accommodation. Each Loan Party shall be bound by any reasonable interpretation made in good faith by Administrative Agent, or any other issuer or correspondent under or in connection with any Letter of Credit
Accommodation or any documents, drafts or acceptances thereunder, notwithstanding that such interpretation may be inconsistent with any instructions of Borrower or any Guarantor. 
 (viii) So long as no Event of Default exists or has occurred and is continuing, Borrower may (A) approve or resolve any questions of
non-compliance of documents, (B) give any instructions as to acceptance or rejection of any documents or goods, (C) execute any and all applications for steamship or airway guaranties, indemnities or delivery orders, and (D) with
Administrative Agent’s and any issuer’s consent, not to be unreasonably withheld, delayed or conditioned, grant any extensions of the maturity of, time of payment for, or time of presentation of, any drafts, acceptances, or documents, and
agree to any amendments, renewals, extensions, modifications, changes or cancellations of any of the terms or conditions of any of the applications, Letter of Credit Accommodations, or documents, drafts or acceptances thereunder or any letters of
credit included in the Collateral. 
  

 41 

 (ix) At any time an Event of Default exists or has occurred and is continuing,
Administrative Agent shall have the right and authority to, and no Loan Party shall, without the prior written consent of Administrative Agent, (A) approve or resolve any questions of non-compliance of documents, (B) give any instructions
as to acceptance or rejection of any documents or goods, (C) execute any and all applications for steamship or airway guaranties, indemnities or delivery orders, (D) grant any extensions of the maturity of, time of payments for, or time of
presentation of, any drafts, acceptances, or documents, and (E) agree to any amendments, renewals, extensions, modifications, changes or cancellations of any of the terms or conditions of any of the applications, Letter of Credit
Accommodations, or documents, drafts or acceptances thereunder or any letters of credit included in the Collateral. Administrative Agent may take such actions either in its own name or in any Loan Party’s name. 
 (x) Any rights, remedies, duties or obligations granted or undertaken by Borrower or any Guarantor to any issuer or correspondent in any
application for any Letter of Credit Accommodation, or any other agreement in favor of any issuer or correspondent relating to any Letter of Credit Accommodation, shall be deemed to have been granted or undertaken by Borrower or such Guarantor to
Administrative Agent for the ratable benefit of the Revolving Credit Lenders. Any duties or obligations undertaken by Administrative Agent to any issuer or correspondent in any application for any Letter of Credit Accommodation, or any other
agreement by Administrative Agent in favor of any issuer or correspondent to the extent relating to any Letter of Credit Accommodation, shall be deemed to have been undertaken by Borrower and Guarantors to Administrative Agent for the ratable
benefit of the Revolving Credit Lenders and to apply in all respects to Borrower and Guarantors. 
 (xi) Immediately upon the
issuance or amendment of any Letter of Credit Accommodation, each Revolving Credit Lender shall be deemed to have irrevocably and unconditionally purchased and received, without recourse or warranty, an undivided interest and participation to the
extent of such Revolving Credit Lender’s Revolving Credit Percentage of the liability with respect to such Letter of Credit Accommodation (including, without limitation, all Obligations with respect thereto). 
 (xii) Borrower is irrevocably and unconditionally obligated, without presentment, demand or protest, to pay to Administrative Agent any
amounts paid by an issuer of a Letter of Credit Accommodation with respect to such Letter of Credit Accommodation (whether through the borrowing of Revolving Credit Loans in accordance with Section 2.04 or otherwise). In the event
that Borrower fails to pay Administrative Agent on the date of any payment under a Letter of Credit Accommodation in an amount equal to the amount of such payment, Administrative Agent (to the extent it has actual notice thereof) shall promptly
notify each Revolving Credit Lender of the unreimbursed amount of such payment and each Revolving Credit Lender agrees, upon one (1) Business Day’s notice, to fund to Administrative Agent the purchase of its participation in such 

  

 42 

 
Letter of Credit Accommodation in an amount equal to its Revolving Credit Percentage of the unpaid amount. The obligation of each Revolving Credit Lender to
deliver to Administrative Agent an amount equal to its respective participation pursuant to the foregoing sentence is absolute and unconditional and such remittance shall be made notwithstanding the occurrence or continuance of any Event of Default,
the failure to satisfy any other condition set forth in Section 5 or any other event or circumstance. If such amount is not made available by a Revolving Credit Lender when due, Administrative Agent shall be entitled to recover
such amount on demand from such Revolving Credit Lender with interest thereon, for each day from the date such amount was due until the date such amount is paid to Administrative Agent at the interest rate then payable by Borrower in respect of Base
Rate Loans as set forth in Section 2.13 hereof. 
 (xiii) Upon Administrative Agent’s request at any
time that an Event of Default has occurred and is continuing, Borrower will either, as Administrative Agent shall specify, furnish cash collateral to the issuer to be used to secure and fund Administrative Agent’s reimbursement obligations to
the issuer in connection with any Letter of Credit Accommodations or furnish cash collateral to Administrative Agent for the Letter of Credit Accommodations. Such cash collateral shall be in an amount equal to one hundred five (105%) percent of
the maximum stated amount of the Letter of Credit Accommodations plus the amount of any fees and expenses payable in connection therewith through the end of the latest expiration date of such Letter of Credit Accommodations. Such cash collateral
shall be remitted by wire transfer in federal funds to such bank account of Administrative Agent, as Administrative Agent may, in its discretion, designate in writing to Borrower for such purpose. In the event that any such Letter of Credit
Accommodations are reduced as a result of any Letter of Credit terminating or expiring undrawn, a corresponding amount of such cash collateral delivered under this Section 3(xiii) shall be applied to repay the remaining Obligations pursuant to
Section 2.16(d)(iii). 
 SECTION 4. REPRESENTATIONS AND WARRANTIES 
 To induce the Agents and the Lenders to enter into this Agreement and to make the Loans and issue or participate in the Letters of Credit, the Borrower
hereby represents and warrants to each Agent and each Lender that: 
 Section 4.01 Financial Condition. 
 The audited consolidated balance sheets of Borrower and its Subsidiaries as at December 31, 2004 and December 31, 2005 and the
related consolidated statements of income and of cash flows for the fiscal years ended on such dates, reported on by and accompanied by an unqualified report from Deloitte & Touche, LLP and the unaudited consolidated balance sheet of the
Borrower and its Subsidiaries as of June 30, 2006 and their related consolidated statements of income and cash flows for the six month period ended on such date, present fairly in all material respects the consolidated financial condition of
Borrower and its Subsidiaries as at such date, and the consolidated results of its operations and its consolidated cash flows for the respective fiscal 

  

 43 

 
years then ended. All such financial statements, including the related schedules and notes thereto, have been prepared in accordance with GAAP applied
consistently throughout the periods involved. The Borrower and its Subsidiaries do not have any material Guarantee Obligations, contingent liabilities and liabilities for taxes, or any long-term leases or unusual forward or long-term commitments,
including, without limitation, any interest rate or foreign currency swap or exchange transaction or other obligation in respect of derivatives, that are not reflected in the most recent financial statements referred to in this paragraph. During the
period from December 31, 2005 to and including the date hereof there has been no Disposition by the Borrower and its Subsidiaries of any material part of its business or Property other than as permitted by Section 7.05.

 Section 4.02 No Change. Except as described in the Company’s filings with the Securities and Exchange Commission from
June 30, 2006 through the Closing Date, since June 30, 2006 there has been no development or event that has had or could reasonably be expected to have a Material Adverse Effect. 
 Section 4.03 Corporate Existence; Compliance with Law. Each of the Borrower and its Restricted Subsidiaries (a) is duly organized, validly
existing and in good standing under the laws of the jurisdiction of its organization, (b) has the corporate power and authority, and the legal right, to own and operate its Property, to lease the Property it operates as lessee and to conduct
the business in which it is currently engaged, (c) is duly qualified as a foreign corporation and in good standing under the laws of each jurisdiction where its ownership, lease or operation of Property or the conduct of its business requires
such qualification, except where the failure to be so qualified would not have a Material Adverse Effect, and (d) is in compliance with all Requirements of Law except to the extent that the failure to comply therewith could not, in the
aggregate, reasonably be expected to have a Material Adverse Effect. 
 Section 4.04 Corporate Power; Authorization; Enforceable
Obligations. Each Loan Party has the corporate power and authority, and the legal right, to make, deliver and perform the Loan Documents to which it is a party and, in the case of the Borrower, to borrow hereunder. Each Loan Party has taken all
necessary corporate or other action to authorize the execution, delivery and performance of the Loan Documents to which it is a party and, in the case of the Borrower, to authorize the borrowings on the terms and conditions of this Agreement. No
consent or authorization of, filing with, notice to or other act by or in respect of, any Governmental Authority or any other Person is required in connection with the borrowings hereunder or the execution, delivery, performance, validity or
enforceability of this Agreement or any of the other Loan Documents, except (i) consents, authorizations, filings and notices that have been obtained or made and are in full force and effect and (ii) the filings, if any, referred to in
Section 4.19. Each Loan Document has been duly executed and delivered on behalf of each Loan Party that is a party thereto. This Agreement constitutes, and each other Loan Document upon execution will constitute, a legal, valid
and binding obligation of each Loan Party that is a party thereto, enforceable against each such Loan Party in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the enforcement of creditors’ rights generally and by general equitable principles (whether enforcement is sought by proceedings in equity or at law). 
  

 44 

 Section 4.05 No Legal Bar. The execution, delivery and performance of this Agreement and the other
Loan Documents, the issuance of Letters of Credit, the borrowings hereunder and the use of the proceeds thereof will not violate any Requirement of Law or any material Contractual Obligation of the Borrower or any of its Restricted Subsidiaries and
will not result in, or require, the creation or imposition of any Lien on any of their respective properties or revenues pursuant to any Requirement of Law or any such Contractual Obligation (other than the Liens created by the Security Documents).

 Section 4.06 No Material Litigation. The Borrower has disclosed to the Agents and the Lenders that certain litigation,
investigations and proceedings exist and are ongoing as more particularly described in the Borrower’s filings with the Securities and Exchange Commission from January 1, 2006 through the Closing Date. No litigation, investigation or
proceeding of or before any arbitrator or Governmental Authority is pending or, to the knowledge of the Borrower, threatened by or against the Borrower or any of its Subsidiaries or against any of their respective properties or revenues
(a) with respect to any of the Loan Documents or any of the transactions contemplated hereby or thereby or (b) that could reasonably be expected to have a Material Adverse Effect. 
 Section 4.07 No Default. Neither the Borrower nor any of its Subsidiaries is in default under or with respect to any of its Contractual
Obligations in any respect that could, individually or in the aggregate for all such defaults, reasonably be expected to have a Material Adverse Effect. No Default or Event of Default has occurred and is continuing. 
 Section 4.08 Ownership of Property; Liens. Each of the Borrower and its Restricted Subsidiaries has title in fee simple to, or a valid leasehold
interest in, all its material real property, and good title to, or a valid leasehold interest in, all its other material Property, and none of such Property is subject to any Lien except as permitted by Section 7.03. 

Section 4.09 Intellectual Property. The Borrower and each of its Restricted Subsidiaries owns, or is licensed to use, all Intellectual Property
necessary for the conduct of its business as currently conducted. No material claim has been asserted and is pending by any Person challenging or questioning the use of any such Intellectual Property or the validity or effectiveness of any such
Intellectual Property that could reasonably be expected to have a Material Adverse Effect, nor does the Borrower know of any valid basis for any such claim. To the best knowledge of the Borrower, the use of such Intellectual Property by the Borrower
and its Restricted Subsidiaries does not infringe on the rights of any Person in a manner that could reasonably be expected to have a Material Adverse Effect. 
 Section 4.10 Taxes. Each of the Borrower and each of its Restricted Subsidiaries has filed or caused to be filed all Federal, state and other material tax returns that are required to be filed and has paid all
taxes shown to be due and payable on said returns or on any assessments made against it or any of its Property and all other taxes, fees or other charges imposed on it or any of its Property by any Governmental Authority (other than any the amount
or validity of which are currently being contested in good faith by appropriate proceedings and with respect to which reserves in conformity with GAAP have been provided on the books of the Borrower or its Subsidiaries, as the case may be); and no
tax Lien has been filed, and, to the knowledge of the Borrower, no claim is being asserted, with respect to any such tax, fee or other charge. 
  

 45 

 Section 4.11 Federal Regulations. No part of the proceeds of any Loans will be used for
“purchasing” or “carrying” any “margin stock” within the respective meanings of each of the quoted terms under Regulation U as now and from time to time hereafter in effect or for any purpose that
violates the provisions of the Regulations of the Board. 
 Section 4.12 Labor Matters. There are no strikes or other labor disputes
against the Borrower or any of its Subsidiaries pending or, to the knowledge of the Borrower, threatened that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect. Hours worked by and payment made to
employees of the Borrower and its Subsidiaries have not been in violation of the Fair Labor Standards Act or any other applicable Requirement of Law dealing with such matters that (individually or in the aggregate) could reasonably be expected to
have a Material Adverse Effect. All payments due from the Borrower or any of its Subsidiaries on account of employee health and welfare insurance that (individually or in the aggregate) could reasonably be expected to have a Material Adverse Effect
if not paid have been paid or accrued as a liability on the books of the Borrower or the relevant Subsidiary. 
 Section 4.13 ERISA.
Neither a Reportable Event (other than a Reportable Event that is waived by regulation) nor an “accumulated funding deficiency” (within the meaning of Section 412 of the Code or Section 302 of ERISA) has
occurred during the five-year period prior to the date on which this representation is made or deemed made with respect to any Plan, and each Plan has complied in all material respects with the applicable provisions of ERISA and the Code. No
termination of a Single Employer Plan has occurred, and no Lien in favor of the PBGC or a Plan has arisen, during such five-year period. The present value of all accrued benefits under each Single Employer Plan (based on those assumptions used to
fund such Plans) did not, as of the last annual valuation date prior to the date on which this representation is made or deemed made, exceed the value of the assets of such Plan allocable to such accrued benefits by a material amount. Neither the
Borrower nor any Commonly Controlled Entity has had a complete or partial withdrawal from any Multiemployer Plan that has resulted or could reasonably be expected to result in a material liability under ERISA, and neither the Borrower nor any
Commonly Controlled Entity would become subject to any material liability under ERISA if the Borrower or any such Commonly Controlled Entity were to withdraw completely from all Multiemployer Plans as of the valuation date most closely preceding the
date on which this representation is made or deemed made. To the knowledge of the Borrower and any Commonly Controlled Entity, no such Multiemployer Plan is in ERISA Reorganization or Insolvent. 
 Section 4.14 Investment Company Act; Other Regulations. No Loan Party is an “investment company”, or a company
“controlled” by an “investment company”, within the meaning of the Investment Company Act of 1940, as amended. No Loan Party is subject to regulation under any Requirement of Law (other than Regulation X of the
Board) which limits its ability to incur Indebtedness of the type it will incur hereunder and under the other Loan Documents. 
 Section
4.15 Subsidiaries. 
 (a) The Subsidiaries listed on Schedule 4.15 constitute all the Subsidiaries of the
Borrower at the date hereof. Schedule 4.15 sets forth as of the Closing Date the name and jurisdiction of incorporation of each Subsidiary and, as to each Subsidiary, the 

  

 46 

 
percentage of each class of Capital Stock owned by each Loan Party and whether such Subsidiary is a Restricted Subsidiary or an Unrestricted Subsidiary.

 (b) There are no outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments (other than
stock options granted to employees or directors and directors’ qualifying shares) of any nature relating to any Capital Stock of any Restricted Subsidiary (other than any Restricted Subsidiary which is a joint venture and for which the Borrower
has delivered notice to the Administrative Agent of any outstanding subscriptions, options, warrants, calls, rights or other agreements or commitments with respect to the Capital Stock of such joint venture). 
 Section 4.16 Use of Proceeds. 
 (a) The proceeds of the Term Loans shall be used to satisfy certain of the indebtedness of the Borrower and certain of its Subsidiaries under the Existing Credit Facility. 
 (b) The proceeds of the Revolving Credit Loans and the Letters of Credit shall be used for general corporate purposes, including working
capital, capital expenditures and permitted acquisitions. 
 Section 4.17 Environmental Matters. Other than exceptions to any of the
following that could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect: 
 (a)
The Borrower and its Subsidiaries: (i) are, and within the period of all applicable statutes of limitation have been, in compliance with all applicable Environmental Laws; (ii) hold all Environmental Permits (each of which is in full force
and effect) required for any of their current or intended operations or for any property owned, leased, or otherwise operated by any of them; (iii) are, and within the period of all applicable statutes of limitation have been, in compliance
with all of their Environmental Permits; and (iv) reasonably believe that: each of their Environmental Permits will be timely renewed and complied with, without material expense; any additional Environmental Permits that may be required of any
of them will be timely obtained and complied with, without material expense; and compliance with any Environmental Law that is or is expected to become applicable to any of them will be timely attained and maintained, without material expense.

 (b) Materials of Environmental Concern are not present at, on, under, in, or about any real property now or formerly owned,
leased or operated by the Borrower or any of its Subsidiaries, or at any other location (including, without limitation, any location to which Materials of Environmental Concern have been sent for re-use or recycling or for treatment, storage, or
disposal) which could reasonably be expected to (i) give rise to liability of the Borrower or any of its Subsidiaries under any applicable Environmental Law or otherwise result in costs to the Borrower or any of its Subsidiaries, or
(ii) interfere with the Borrower’s or any of its Subsidiaries’ continued operations, or 

  

 47 

 
(iii) impair the fair saleable value of any real property owned or leased by the Borrower or any of its Subsidiaries. 
 (c) There is no judicial, administrative, or arbitral proceeding (including any notice of violation or alleged violation) under or
relating to any Environmental Law to which the Borrower or any of its Subsidiaries is, or to the knowledge of the Borrower or any of its Subsidiaries will be, named as a party that is pending or, to the knowledge of the Borrower or any of its
Subsidiaries, threatened. 
 (d) Neither the Borrower nor any of its Subsidiaries has received any written request for
information, or been notified that it is a potentially responsible party under or relating to the federal Comprehensive Environmental Response, Compensation, and Liability Act or any similar Environmental Law, or with respect to any Materials of
Environmental Concern. 
 (e) Neither the Borrower nor any of its Subsidiaries has entered into or agreed to any consent
decree, order, or settlement or other agreement, or is subject to any judgment, decree, or order or other agreement, in any judicial, administrative, arbitral, or other forum for dispute resolution, relating to compliance with or liability under any
Environmental Law. 
 (f) Neither the Borrower nor any of its Subsidiaries has assumed or retained, by contract or operation
of law, any liabilities of any kind, fixed or contingent, known or unknown, under any Environmental Law or with respect to any Material of Environmental Concern. 
 Section 4.18 Accuracy of Information, etc. No statement or information contained in this Agreement, any other Loan Document, the Information Certificate or any other document, certificate or statement furnished
to the Agents or the Lenders or any of them, by or on behalf of any Loan Party for use in connection with the transactions contemplated by this Agreement or the other Loan Documents, contained as of the date such statement, information, document or
certificate was so furnished, any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements contained herein or therein not misleading. The projections and pro forma financial information
contained in the materials referenced above are based upon good faith estimates and assumptions believed by management of the Borrower to be reasonable at the time made, it being recognized by the Lenders that such financial information as it
relates to future events is not to be viewed as fact and that actual results during the period or periods covered by such financial information may differ from the projected results set forth therein by a material amount. There is no fact known to
any Loan Party that could reasonably be expected to have a Material Adverse Effect that has not been expressly disclosed herein, in the other Loan Documents, the Information Certificate, or in any other documents, certificates and statements
furnished to the Agents and the Lenders for use in connection with the transactions contemplated hereby and by the other Loan Documents. 
 Section 4.19 Security Documents. The Guarantee and Collateral Agreement is effective to create in favor of the Collateral Agent, for the benefit of the Lenders, a legal, valid and enforceable security interest in the Collateral
described therein and proceeds thereof. In the 

  

 48 

 
case of the Pledged Stock described in the Guarantee and Collateral Agreement, when any stock certificates representing such Pledged Stock are delivered to
the Collateral Agent, and in the case of the other Collateral described in the Guarantee and Collateral Agreement, when financing statements in appropriate form are filed in the offices specified on Schedule 4.19 (which financing
statements have been duly completed and delivered to the Collateral Agent) and such other filings as are specified on Schedule 3 to the Guarantee and Collateral Agreement have been completed, the Guarantee and Collateral Agreement shall
constitute a fully perfected Lien on, and security interest in, all right, title and interest of the Loan Parties in such Collateral and the proceeds thereof, as security for the Obligations (as defined in the Guarantee and Collateral Agreement), in
each case prior and superior in right to any other Person (except, in the case of Collateral other than Pledged Stock, Liens permitted by Section 7.03). 
 Section 4.20 Solvency. Each Loan Party is, and after giving effect to the incurrence of all Indebtedness and obligations being incurred in
connection herewith and therewith will be and will continue to be, Solvent. 
 Section 4.21 Senior Indebtedness. The Obligations
constitute “Senior Debt” of the Borrower under and as defined in the Senior Subordinated Note Indenture. The obligations of each Restricted Subsidiary under the Guarantee and Collateral Agreement constitute “Senior
Debt” of such Restricted Subsidiary under and as defined in the Senior Subordinated Note Indenture. 
 Section 4.22
Compounding. Since May 1, 2006, the Borrower and its Subsidiaries have not engaged in compounding of products or other Inventory (other than Budesonide) with an aggregate fair market value in excess of $50,000 during any calendar year.

 Section 4.23 Location of Material Inventory, Equipment and Other Property. Schedule 4.23 sets forth all locations in
the United States where the aggregate value of Inventory, Equipment or other tangible Property owned by the Loan Parties exceeds $250,000.

 SECTION 9. THE AGENTS 
 Section 9.01 Appointment. Each Lender hereby irrevocably designates and appoints the Agents as the agents of such Lender under this Agreement and
the other Loan Documents, and each Lender irrevocably authorizes each Agent, in such capacity, to take such action on its behalf under the provisions of this Agreement and the other Loan Documents and to exercise such powers and perform such duties
as are expressly delegated to such Agent by the terms of this Agreement and the other Loan Documents, together with such other powers as are reasonably incidental thereto. Notwithstanding any provision to the contrary elsewhere in this Agreement, no
Agent shall have any duties or responsibilities, except those expressly set forth herein, or any fiduciary relationship with any Lender, and no implied covenants, functions, responsibilities, duties, obligations or liabilities shall be read into
this Agreement or any other Loan Document or otherwise exist against any Agent. 
 Section 9.02 Delegation of Duties. Each Agent may
execute any of its duties under this Agreement and the other Loan Documents by or through agents or attorneys-in-fact and shall be entitled to advice of counsel concerning all matters pertaining to such duties. No Agent shall be responsible for the
negligence or misconduct of any agents or attorneys-in-fact selected by it with reasonable care. 
 Section 9.03 Exculpatory
Provisions. Neither any Agent nor any of its officers, directors, employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any action lawfully taken or omitted to be taken by it or such Person under or in connection with
this Agreement or any other Loan Document (except to the extent that any of the foregoing are found by a final decision of a court of competent jurisdiction to have resulted from its or such Person’s own gross negligence or willful misconduct)
or (ii) responsible in any manner to any of the Lenders for any recitals, statements, representations or warranties made by any Loan Party or any officer thereof contained in this Agreement or any other Loan Document or in any certificate,
report, statement or other document referred to or provided for in, or received by the Agents under or in connection with, this Agreement or any other Loan Document or for the value, validity, effectiveness, genuineness, enforceability or
sufficiency of this Agreement or any other Loan Document or for any failure of any Loan Party to perform its obligations hereunder or thereunder. The Agents shall not be under any obligation to any Lender to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions of, this Agreement or any other Loan Document, or to inspect the properties, books or records of any Loan Party. 
 Section 9.04 Reliance by Agents. Each Agent shall be entitled to rely, and shall be fully protected in relying, upon any instrument, writing,
resolution, notice, consent, certificate, affidavit, letter, telecopy, telex or teletype message, statement, order or other document or conversation believed by it to be genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including, without limitation, counsel to the Loan Parties), independent accountants and other experts selected by such Agent. The Agents may deem and treat the payee of any Note as the
owner thereof for all purposes unless such Note shall have been transferred in accordance with Section 10.06 and all actions required by such Section in connection with such transfer shall have been taken. Each Agent shall be
fully justified in failing or refusing to take any action under this Agreement or any 

  

 74 

 
other Loan Document unless it shall first receive such advice or concurrence of the Required Lenders (or, if so specified by this Agreement, all Lenders or
any other instructing group of Lenders specified by this Agreement) as it deems appropriate or it shall first be indemnified to its satisfaction by the Lenders against any and all liability and expense that may be incurred by it by reason of taking
or continuing to take any such action. Each Agent shall in all cases be fully protected in acting, or in refraining from acting, under this Agreement and the other Loan Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement), and such request and any action taken or failure to act pursuant thereto shall be binding upon all the Lenders and all future holders of
the Loans. 
 Section 9.05 Notice of Default. No Agent shall be deemed to have knowledge or notice of the occurrence of any Default or
Event of Default hereunder unless such Agent shall have received notice from a Lender or the Borrower referring to this Agreement, describing such Default or Event of Default and stating that such notice is a “notice of default”. In
the event that the Administrative Agent shall receive such a notice, the Administrative Agent shall give notice thereof to the Collateral Agent and Lenders. Each Agent shall take such action with respect to such Default or Event of Default as shall
be reasonably directed by the Required Lenders (or, if so specified by this Agreement, all Lenders or any other instructing group of Lenders specified by this Agreement); provided that unless and until such Agent shall have received such directions,
such Agent may (but shall not be obligated to) take such action, or refrain from taking such action, with respect to such Default or Event of Default as it shall deem advisable in the best interests of the Lenders. 
 Section 9.06 Non-Reliance on Agents and Other Lenders. Each Lender expressly acknowledges that neither any of the Agents nor any of their
respective officers, directors, employees, agents, attorneys-in-fact or affiliates have made any representations or warranties to it and that no act by any Agent hereafter taken, including any review of the affairs of a Loan Party or any affiliate
of a Loan Party, shall be deemed to constitute any representation or warranty by any Agent to any Lender. Each Lender represents to the Agents that it has, independently and without reliance upon any Agent or any other Lender, and based on such
documents and information as it has deemed appropriate, made its own appraisal of and investigation into the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates and made its own
decision to make its Loans hereunder and enter into this Agreement. Each Lender also represents that it will, independently and without reliance upon any Agent or any other Lender, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own credit analysis, appraisals and decisions in taking or not taking action under this Agreement and the other Loan Documents, and to make such investigation as it deems necessary to inform itself as to
the business, operations, property, financial and other condition and creditworthiness of the Loan Parties and their affiliates. Except for notices, reports and other documents expressly required to be furnished to the Lenders by the Administrative
Agent hereunder, no Agent shall have any duty or responsibility to provide any Lender with any credit or other information concerning the business, operations, property, condition (financial or otherwise), prospects or creditworthiness of any Loan
Party or any affiliate of a Loan Party that may come into the possession of such Agent or any of its officers, directors, employees, agents, attorneys-in-fact or affiliates. 
  

 75 

 Section 9.07 Indemnification. The Lenders agree to indemnify each Agent in its capacity as such
(to the extent not reimbursed by the Borrower and without limiting the obligation of the Borrower to do so), ratably according to their respective Aggregate Exposure Percentages in effect on the date on which indemnification is sought under this
Section (or, if indemnification is sought after the date upon which the Commitments shall have terminated and the Loans shall have been paid in full, ratably in accordance with such Aggregate Exposure Percentages immediately prior to
such date), for, and to save each Agent harmless from and against, any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind whatsoever that may at any time (including,
without limitation, at any time following the payment of the Loans) be imposed on, incurred by or asserted against such Agent in any way relating to or arising out of, the Commitments, this Agreement, any of the other Loan Documents or any documents
contemplated by or referred to herein or therein or the transactions contemplated hereby or thereby or any action taken or omitted by such Agent under or in connection with any of the foregoing; provided that no Lender shall be liable for the
payment of any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements that are found by a final decision of a court of competent jurisdiction to have resulted from such
Agent’s gross negligence or willful misconduct. The agreements in this Section shall survive the payment of the Loans and all other amounts payable hereunder. 
 Section 9.08 Agent in Its Individual Capacity. Each Agent and its affiliates may make loans to, accept deposits from and generally engage in any
kind of business with any Loan Party as though such Agent were not an Agent. With respect to its Loans made or renewed by it and with respect to any Letter of Credit Accommodation issued or participated in by it, each Agent shall have the same
rights and powers under this Agreement and the other Loan Documents as any Lender and may exercise the same as though it were not an Agent, and the terms “Lender” and “Lenders” shall include each Agent
in its individual capacity. 
 Section 9.09 Successor Agents. The Administrative Agent or the Collateral Agent may resign upon 30
days’ notice to the Lenders and the Borrower. If the Administrative Agent or the Collateral Agent shall resign under this Agreement and the other Loan Documents, then the Required Lenders shall appoint from among the Lenders a successor agent
for the Lenders, which successor agent shall (unless an Event of Default under Section 8(a) or Section 8(f) with respect to the Borrower shall have occurred and be continuing) be subject to approval by the
Borrower (which approval shall not be unreasonably withheld or delayed), whereupon such successor agent shall succeed to the rights, powers and duties of the Administrative Agent or the Collateral Agent, as the case may be, and the term
“Administrative Agent” or “Collateral Agent,” as applicable, shall mean such successor agent effective upon such appointment and approval, and the former Administrative Agent’s or the former
Collateral Agent’s, as applicable, rights, powers and duties as Administrative Agent or Collateral Agent, as the case may be, shall be terminated, without any other or further act or deed on the part of such former Administrative Agent or
former Collateral Agent or any of the parties to this Agreement or any holders of the Loans. If no successor agent has accepted appointment as Administrative Agent by the date that is 30 days following a retiring Administrative Agent’s notice
of resignation, the retiring Administrative Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Administrative Agent hereunder until such time, if any, as the
Required Lenders appoint a successor agent as provided for above. If no 

  

 76 

 
successor agent has accepted appointment as Collateral Agent by the date that is 30 days following a retiring Collateral Agent’s notice of resignation,
the retiring Collateral Agent’s resignation shall nevertheless thereupon become effective, and the Administrative Agent shall assume and perform all of the duties of the Collateral Agent hereunder until such time, if any, as the Required
Lenders appoint a successor agent as provided for above. In any event the retiring Collateral Agent shall transfer all its rights as Collateral Agent in respect of the Loan Documents and the Collateral to its successor. After any retiring
Agent’s resignation as Agent, the provisions of this Section 9 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents. 

Section 9.10 Authorization to Release Liens and Guarantees. The Administrative Agent and the Collateral Agent are hereby irrevocably authorized
by each of the Lenders to effect any release of Liens or guarantee obligations contemplated by Section 10.15. 
 Section 9.11 The Arranger. The Arranger, in its capacity as such, shall have no duties or responsibilities, and shall incur no liability, under this Agreement and the other Loan Documents. 
 SECTION 10. MISCELLANEOUS 
 Section
10.01 Amendments and Waivers. (a) Neither this Agreement or any other Loan Document, nor any terms hereof or thereof may be amended, supplemented or modified except in accordance with the provisions of this Section 10.01.
The Required Lenders and each Loan Party party to the relevant Loan Document may, or (with the written consent of the Required Lenders) the Agents and each Loan Party party to the relevant Loan Document may, from time to time, (a) enter into
written amendments, supplements or modifications hereto and to the other Loan Documents (including amendments and restatements hereof or thereof) for the purpose of adding any provisions to this Agreement or the other Loan Documents or changing in
any manner the rights of the Lenders or of the Loan Parties hereunder or thereunder or (b) waive, on such terms and conditions as may be specified in the instrument of waiver, any of the requirements of this Agreement or the other Loan
Documents or any Default or Event of Default and its consequences; provided, however, that no such waiver and no such amendment, supplement or modification shall: 
 (i) forgive the principal amount or extend the final scheduled date of maturity of any Loan or Reimbursement Obligation, extend the
scheduled date of any amortization payment in respect of any Term Loan, reduce the stated rate of any interest or fee payable hereunder or extend the scheduled date of any payment thereof, increase the amount or extend the expiration date of any
Commitment of any Lender, in each case without the consent of each Lender directly affected thereby; 
 (ii) amend, modify or
waive any provision of this Section or reduce any percentage specified in the definition of Required Lenders, consent to the assignment or transfer by the Borrower of any of its rights and obligations under this Agreement and the other
Loan Documents, release all or substantially all of the Collateral or release all or substantially all of the Restricted Subsidiaries from 

  

 77 

 
their guarantee obligations under the Guarantee and Collateral Agreement, in each case without the consent of all Lenders; 
 (iii) amend, modify or waive any condition precedent to any extension of credit under the Revolving Credit Facility set forth in
Section 5.02 (including, without limitation, the waiver of an existing Default or Event of Default required to be waived in order for such extension of credit to be made) without the consent of the Majority Revolving Credit
Facility Lenders; 
 (iv) reduce the percentage specified in the definition of Majority Facility Lenders with respect to any
Facility without the written consent of all Lenders under such Facility; 
 (v) amend, modify or waive any provision of
Section 9 without the consent of any Agent directly affected thereby; 
 (vi) amend, modify or waive any
provision of Section 2.16 without the consent of each Lender directly affected thereby; or 
 (vii) amend,
modify or waive any provision of Section 3 without the consent of any Issuing Lender. 
 Any such waiver and any such amendment, supplement or
modification shall apply equally to each of the Lenders and shall be binding upon the Loan Parties, the Lenders, the Agents and all future holders of the Loans. In the case of any waiver, the Loan Parties, the Lenders and the Agents shall be
restored to their former position and rights hereunder and under the other Loan Documents, and any Default or Event of Default waived shall be deemed to be cured and not continuing; but no such waiver shall extend to any subsequent or other Default
or Event of Default, or impair any right consequent thereon. Any such waiver, amendment, supplement or modification shall be effected by a written instrument signed by the parties required to sign pursuant to the foregoing provisions of this
Section; provided that delivery of an executed signature page of any such instrument by facsimile transmission shall be effective as delivery of a manually executed counterpart thereof. 
 (b) If, in connection with any proposed amendment, supplement, modification or waiver to any of the provisions of this Agreement as
contemplated by clause (ii) of the proviso to paragraph (a) above, the consent of the Required Lenders is obtained but the consent of one or more of such other Lenders whose consent is required is not obtained, then the Borrower
shall have the right, so long as all non-consenting Lenders whose individual consent is required are treated as described in either clauses (x) or (y) below, to either (x) replace each such non-consenting Lender or
Lenders with one or more replacement Lenders (each a “Replacement Lender”) so long as at the time of such replacement, (i) each such Replacement Lender consents to the proposed amendment, supplement, modification or waiver,
(ii) no Event of Default shall have occurred and be continuing at the time of such replacement, (iii) the Replacement Lenders as a group shall purchase, at par, all Loans and other amounts owing to such replaced Lenders as a group on or
prior to the date of replacement, (iv) the Replacement Lender, if not already a 

  

 78 

 
Lender, shall be reasonably satisfactory to the Administrative Agent, (v) the replaced Lender shall be obligated to make such replacement in accordance
with Section 10.06 (provided that the Borrower shall be obligated to pay the registration and processing fee referred to therein) and (vi) any such replacement shall not be deemed a waiver of any rights that the Borrower, the
Administrative Agent, the Collateral Agent or any other Lender shall have against the replaced Lender, or (y) terminate such non-consenting Lender’s Revolving Credit Commitment, and repay any Revolving Credit Loans and Term Loans, provided
that, unless such non-consenting Lender’s Commitments terminated and Loans repaid pursuant to the preceding clause (x) are immediately replaced in full at such time through the addition of Replacement Lenders or the increase of
Commitments and/or outstanding Loans of the remaining Lenders (in each case, which must specifically consent thereto), then in the case of any action pursuant to the preceding clause (x), the Required Lenders (as determined prior to giving
effect to the proposed action) shall specifically consent thereto, provided further, that in any event, the Borrower shall not have the right to replace a Lender, terminate its Revolving Commitment or repay its Loans solely as a result of the
exercise of such Lender’s rights (and the withholding of any required consent by such Lender) pursuant to any clause (other than clause (ii)) of the proviso to subsection (a) above. 
 Section 10.02 Notices. All notices, requests and demands to or upon the respective parties hereto to be effective shall be in writing (including
by telecopy), and, unless otherwise expressly provided herein, shall be given by overnight delivery service, by telecopy, by hand or by certified mail, return receipt requested, and shall be effective upon receipt or refusal of such notice and shall
be sent addressed (a) in the case of the Borrower and the Agents, as follows and (b) in the case of the Lenders, as set forth in an administrative questionnaire delivered to the Administrative Agent or, in the case of a Lender which
becomes a party to this Agreement pursuant to an Assignment and Acceptance, in such Assignment and Acceptance or (c) in the case of any party, to such other address as such party may hereafter notify to the other parties hereto:

 provided that any notice, request or demand to or upon the any Agent, or any Lender shall not be effective until
received. 
 Section 10.03 No Waiver; Cumulative Remedies. No failure to exercise and no delay in exercising, on the part of any Agent
or any Lender, any right, remedy, power or privilege hereunder or under the other Loan Documents shall operate as a waiver thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder preclude any other or
further exercise thereof or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges herein provided are cumulative and not exclusive of any rights, remedies, powers and privileges provided by law.

 Section 10.04 Survival of Representations and Warranties. All representations and warranties made herein, in the other Loan
Documents and in any document, certificate or statement delivered pursuant hereto or in connection herewith shall survive the execution and delivery of this Agreement and the making of the Loans and other extensions of credit hereunder. 

Section 10.05 Payment of Expenses. The Borrower agrees (a) to pay or reimburse the Agents for all their reasonable out-of-pocket costs and
expenses incurred in connection with the syndication of the Facilities (other than fees payable to syndicate members) and the development, preparation and execution of, and any amendment, supplement or modification to, this Agreement and the other
Loan Documents and any other documents prepared in connection herewith or therewith, and the consummation and administration of the transactions contemplated hereby and thereby, including, without limitation, the reasonable fees and disbursements
and other charges of counsel to the Administrative Agent and the charges of Intralinks, (b) to pay or reimburse each Lender and the Agents for all their costs and expenses incurred in connection with the enforcement or preservation of any
rights under this Agreement, the other Loan Documents and any other documents prepared in connection herewith or therewith, including, without limitation, the fees and disbursements of counsel (including the allocated fees and disbursements and
other charges of in-house counsel) to each Lender and of counsel to the Agents, (c) to pay, indemnify, or reimburse each Lender and the Agents for, and hold each Lender and the Agents harmless from, any and all recording and filing fees and any
and all liabilities with respect to, or resulting from any delay in paying, stamp, excise and other taxes, if any, which may be payable or determined to be payable in connection with the 

  

 80 

 
execution and delivery of, or consummation or administration of any of the transactions contemplated by, or any amendment, supplement or modification of, or
any waiver or consent under or in respect of, this Agreement, the other Loan Documents and any such other documents, and (d) to pay, indemnify or reimburse each Lender, each Agent, their respective affiliates, and their respective officers,
directors, trustees, employees, advisors, agents and controlling persons (each, an “Indemnitee”) for, and hold each Indemnitee harmless from and against any and all other liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever with respect to the execution, delivery, enforcement, performance and administration of this Agreement, the other Loan Documents and any such other
documents, including, without limitation, any of the foregoing relating to the use of proceeds of the Loans or the violation of, noncompliance with or liability under, any Environmental Law applicable to the operations of the Borrower any of its
Subsidiaries or any of the Properties and the fees and disbursements and other charges of legal counsel in connection with claims, actions or proceedings by any Indemnitee against the Borrower hereunder (all the foregoing in this clause
(d), collectively, the “Indemnified Liabilities”), provided that the Borrower shall have no obligation hereunder to any Indemnitee with respect to Indemnified Liabilities to the extent such Indemnified Liabilities are
found by a final decision of a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of such Indemnitee. No Indemnitee shall be liable for any damages arising from the use by unauthorized persons of
Information or other materials sent through electronic, telecommunications or other information transmission systems that are intercepted by such persons or for any special, indirect, consequential or punitive damages in connection with the
Facilities. Without limiting the foregoing, and to the extent permitted by applicable law, the Borrower agrees not to assert and to cause its Subsidiaries not to assert, and hereby waives and agrees to cause its Subsidiaries so to waive, all rights
for contribution or any other rights of recovery with respect to all claims, demands, penalties, fines, liabilities, settlements, damages, costs and expenses of whatever kind or nature, under or related to Environmental Laws, that any of them might
have by statute or otherwise against any Indemnitee. All amounts due under this Section shall be payable not later than 10 days after written demand therefor. Statements payable by the Borrower pursuant to this Section
shall be submitted to Chief Financial Officer (Telephone No. (407) 822-4600) (Fax No. (407) 297- 1906), at the address of the Borrower set forth in Section 10.02, or to such other Person or address as may be
hereafter designated by the Borrower in a notice to the Administrative Agent. The agreements in this Section shall survive repayment of the Loans and all other amounts payable hereunder. 
 Section 10.06 Successors and Assigns; Participations and Assignments. 
 (a) This Agreement shall be binding upon and inure to the benefit of the Borrower, the Lenders, the Agents, all future holders of the
Loans and their respective successors and assigns, except that the Borrower may not assign or transfer any of its rights or obligations under this Agreement without the prior written consent of the Agents and each Lender. 
 (b) Any Lender may, without the consent of the Borrower, in accordance with applicable law, at any time sell to one or more banks,
financial institutions or other entities (each, a “Participant”) participating interests in any Loan owing to such Lender, any Commitment of such Lender or any other interest of such Lender hereunder and 

  

 81 

 
under the other Loan Documents. In the event of any such sale by a Lender of a participating interest to a Participant, such Lender’s obligations under
this Agreement to the other parties to this Agreement shall remain unchanged, such Lender shall remain solely responsible for the performance thereof, such Lender shall remain the holder of any such Loan for all purposes under this Agreement and the
other Loan Documents, and the Borrower and the Agents shall continue to deal solely and directly with such Lender in connection with such Lender’s rights and obligations under this Agreement and the other Loan Documents. In no event shall any
Participant under any such participation have any right to approve any amendment or waiver of any provision of any Loan Document, or any consent to any departure by any Loan Party therefrom, except to the extent that such amendment, waiver or
consent would require the consent of all Lenders pursuant to Section 10.01. The Borrower agrees that if amounts outstanding under this Agreement and the Loans are due or unpaid, or shall have been declared or shall have become due
and payable upon the occurrence of an Event of Default, each Participant shall, to the maximum extent permitted by applicable law, be deemed to have the right of setoff in respect of its participating interest in amounts owing under this Agreement
to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement, provided that, in purchasing such participating interest, such Participant shall be deemed to have agreed to share with the
Lenders the proceeds thereof as provided in Section 10.07(a) as fully as if such Participant were a Lender hereunder. The Borrower also agrees that each Participant shall be entitled to the benefits of Sections 2.17,
2.18 and 2.19 with respect to its participation in the Commitments and the Loans outstanding from time to time as if such Participant were a Lender; provided that, in the case of Section 2.18, such
Participant shall have complied with the requirements of said Section, and provided, further, that no Participant shall be entitled to receive any greater amount pursuant to any such Section than the transferor Lender would have been entitled to
receive in respect of the amount of the participation transferred by such transferor Lender to such Participant had no such transfer occurred. 
 (c) Any Lender (an “Assignor”) may, in accordance with applicable law and upon written notice to the Administrative Agent, at any time and from time to time assign to any Lender or any
Affiliate, Related Fund or Control Investment Affiliate thereof or with the consent of the Borrower and the Administrative Agent and, in the case of any assignment of Revolving Credit Commitments, the written consent of the Issuing Lender (which, in
each case, shall not be unreasonably withheld or delayed) (provided (x) that no such consent need be obtained by any Agent and (y) the consent of the Borrower need not be obtained upon the occurrence and during the continuation of a
Default or an Event of Default), to an additional bank, financial institution or other entity (an “Assignee”) all or any part of its rights and obligations under this Agreement pursuant to an Assignment and Acceptance,
substantially in the form of Exhibit D, executed by such Assignee and such Assignor (and, where the consent of the Borrower, the Administrative Agent or the Issuing Lender is required pursuant to the foregoing provisions, by the
Borrower and such other Persons) and delivered to the Administrative Agent for its acceptance and recording in the Register; provided that no such assignment to an Assignee (other than any Lender or any affiliate, Related Fund or Control Investment
Affiliate thereof) shall be in an aggregate principal amount of less than $1,000,000 (other than in the case of an assignment of all of a Lender’s interests under this Agreement), unless otherwise agreed 

  

 82 

 
by the Borrower and the Administrative Agent. An Assignor shall use commercially reasonable efforts to assure that any Assignee to which it assigns its
Commitments and/or Loans that is a Non-U.S. Lender shall be able to deliver the applicable forms and certificates required under Section 2.18(d) claiming full exemption from U.S. federal withholding taxes as of the date of such assignment. Upon
such execution, delivery, acceptance and recording, from and after the effective date determined pursuant to such Assignment and Acceptance, (x) the Assignee thereunder shall be a party hereto and, to the extent provided in such Assignment and
Acceptance, have the rights and obligations of a Lender hereunder with Commitments and/or Loans as set forth therein, and (y) the Assignor thereunder shall, to the extent provided in such Assignment and Acceptance, be released from its
obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of an Assignor’s rights and obligations under this Agreement, such Assignor shall cease to be a party hereto, except as to
Section 2.17, 2.18 and 10.05 in respect of the period prior to such effective date). Notwithstanding any provision of this Section, the consent of the Borrower shall not be required for
any assignment that occurs at any time when any Event of Default shall have occurred and be continuing. For purposes of the minimum assignment amounts set forth in this paragraph, multiple assignments by two or more Related Funds shall be
aggregated. 
 (d) The Administrative Agent shall, on behalf of the Borrower, maintain at its address referred to in
Section 10.02 a copy of each Assignment and Acceptance delivered to it and a register (the “Register”) for the recordation of the names and addresses of the Lenders and the Commitment of, and principal
amount of the Loans owing to, each Lender from time to time. The entries in the Register shall be conclusive, in the absence of manifest error, and the Borrower, each Agent and the Lenders shall treat each Person whose name is recorded in the
Register as the owner of the Loans and any Notes evidencing such Loans recorded therein for all purposes of this Agreement. Any assignment of any Loan, whether or not evidenced by a Note, shall be effective only upon appropriate entries with respect
thereto being made in the Register (and each Note shall expressly so provide). Any assignment or transfer of all or part of a Loan evidenced by a Note shall be registered on the Register only upon surrender for registration of assignment or transfer
of the Note evidencing such Loan, accompanied by a duly executed Assignment and Acceptance; thereupon one or more new Notes in the same aggregate principal amount shall be issued to the designated Assignee, and the old Notes shall be returned by the
Administrative Agent to the Borrower marked “canceled”. The Register shall be available for inspection by the Borrower or any Lender (with respect to any entry relating to such Lender’s Loans) at any reasonable time and from
time to time upon reasonable prior notice. 
 (e) Upon its receipt of an Assignment and Acceptance executed by an Assignor and
an Assignee (and, in any case where the consent of any other Person is required by Section 10.06(c), by each such other Person) together with payment to the Administrative Agent of a registration and processing fee of $3,500
(treating multiple, simultaneous assignments by or to two or more Related Funds as a single assignment) (except that no such registration and processing fee shall be payable (y) in connection with an assignment by or to any Agent or (z) in
the case of an Assignee which is already a Lender or is an affiliate or Related Fund or Control Investment Affiliate of a Lender or 

  

 83 

 
a Person under common management with a Lender), the Administrative Agent shall (i) promptly accept such Assignment and Acceptance and
(ii) on the effective date determined pursuant thereto record the information contained therein in the Register and give notice of such acceptance and recordation to the Borrower. On or prior to such effective date, the Borrower, at its own
expense, upon request, shall execute and deliver to the Administrative Agent (in exchange for the Revolving Credit Note and/or Term Note, as the case may be, of the assigning Lender) a new Revolving Credit Note and/or Term Note, as the case may be,
to the order of such Assignee in an amount equal to the Revolving Credit Commitment and/or Term Loan, as the case may be, assumed or acquired by it pursuant to such Assignment and Acceptance and, if the Assignor has retained a Revolving Credit
Commitment and/or Term Loan, as the case may be, upon request, a new Revolving Credit Note and/or Term Note, as the case may be, to the order of the Assignor in an amount equal to the Revolving Credit Commitment and/or Term Loan, as the case may be,
retained by it hereunder. Such new Note or Notes, if any, shall be dated the Closing Date and shall otherwise be in the form of the Note or Notes replaced thereby. 
 (f) For avoidance of doubt, the parties to this Agreement acknowledge that the provisions of this Section concerning
assignments of Loans and Notes relate only to absolute assignments and that such provisions do not prohibit assignments creating security interests in Loans and Notes, including, without limitation, any pledge or assignment by a Lender of any Loan
or Note to any Federal Reserve Bank in accordance with applicable law; provided that, the Borrower may replace any assignee or pledgee that becomes a Lender pursuant to an assignment or pledge permitted by this Section 10.06(f) in
accordance with clause (x) or (y) of Section 10.01(b). 
 (g) Notwithstanding anything to
the contrary contained herein, any Lender (a “Granting Lender”) may grant to a special purpose funding vehicle (an “SPC”), identified as such in writing from time to time by the Granting Lender to the
Administrative Agent and the Borrower, the option to provide to the Borrower all or any part of any Loan that such Granting Lender would otherwise be obligated to make to the Borrower pursuant to this Agreement; provided that (i) nothing herein
shall constitute a commitment by any SPC to make any Loan and (ii) if an SPC elects not to exercise such option or otherwise fails to provide all or any part of such Loan, the Granting Lender shall be obligated to make such Loan pursuant to the
terms hereof. The making of a Loan by an SPC hereunder shall utilize the Commitment of the Granting Lender to the same extent, and as if, such Loan were made by such Granting Lender. Each party hereto hereby agrees that no SPC shall be liable for
any indemnity or similar payment obligation under this Agreement (all liability for which shall remain with the Granting Lender). In furtherance of the foregoing, each party hereto hereby agrees (which agreement shall survive the termination of this
Agreement) that, prior to the date that is one year and one day after the payment in full of all outstanding commercial paper or other indebtedness of any SPC, it will not institute against, or join any other person in instituting against, such SPC
any bankruptcy, reorganization, arrangement, insolvency or liquidation proceedings under the laws of the United States or any state thereof. In addition, notwithstanding anything to the contrary in this Section 10.06(g), any SPC
may (A) with notice to, but without the prior written consent of, the Borrower and the Administrative Agent and 

  

 84 

 
without paying any processing fee therefor, assign all or a portion of its interests in any Loans to the Granting Lender, or with the prior written consent
of the Borrower and the Administrative Agent (which consent shall not be unreasonably withheld) to any financial institutions providing liquidity and/or credit support to or for the account of such SPC to support the funding or maintenance of Loans,
and (B) disclose on a confidential basis any non-public information relating to its Loans to any rating agency, commercial paper dealer or provider of any surety, guarantee or credit or liquidity enhancement to such SPC; provided that
non-public information with respect to the Borrower may be disclosed only with the Borrower’s consent which will not be unreasonably withheld. This paragraph (g) may not be amended without the written consent of any SPC with Loans
outstanding at the time of such proposed amendment. 
 Section 10.07 Adjustments; Set-off. 
 (a) Except to the extent that this Agreement provides for payments to be allocated to a particular Lender or to the Lenders under a
particular Facility, if any Lender (a “Benefited Lender”) shall at any time receive any payment of all or part of the Obligations owing to it, or receive any collateral in respect thereof (whether voluntarily or
involuntarily, by set-off, pursuant to events or proceedings of the nature referred to in Section 8(f), or otherwise), in a greater proportion than any such payment to or collateral received by any other Lender, if any, in respect
of such other Lender’s Obligations, such Benefited Lender shall purchase for cash from the other Lenders a participating interest in such portion of each such other Lender’s Obligations, or shall provide such other Lenders with the
benefits of any such collateral, as shall be necessary to cause such Benefited Lender to share the excess payment or benefits of such collateral ratably with each of the Lenders; provided, however, that if all or any portion of such excess payment
or benefits is thereafter recovered from such Benefited Lender, such purchase shall be rescinded, and the purchase price and benefits returned, to the extent of such recovery, but without interest. 
 (b) In addition to any rights and remedies of the Lenders provided by law, each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by the Borrower to the extent permitted by applicable law, upon any amount becoming due and payable by the Borrower hereunder (whether at the stated maturity, by acceleration or otherwise), to set off
and appropriate and apply against such amount any and all deposits (general or special, time or demand, provisional or final), in any currency, and any other credits, indebtedness or claims, in any currency, in each case whether direct or indirect,
absolute or contingent, matured or unmatured, at any time held or owing by such Lender or any branch or agency thereof to or for the credit or the account of the Borrower. Each Lender agrees promptly to notify the Borrower and the Administrative
Agent after any such setoff and application made by such Lender, provided that the failure to give such notice shall not affect the validity of such setoff and application. 
 Section 10.08 Counterparts. This Agreement may be executed by one or more of the parties to this Agreement on any number of separate counterparts,
and all of said counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an 

  

 85 

 
executed signature page of this Agreement by facsimile transmission shall be effective as delivery of a manually executed counterpart hereof. A set of the
copies of this Agreement signed by all the parties shall be lodged with the Borrower and the Administrative Agent. 
 Section 10.09
Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining
provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. 
 Section 10.10 Integration. This Agreement, the Fee Letters and the other Loan Documents represent the entire agreement of the Borrower, the Agents, the Arranger and the Lenders with respect to the subject
matter hereof and thereof, and there are no promises, undertakings, representations or warranties by the Arranger, any Agent or any Lender relative to subject matter hereof not expressly set forth or referred to herein, in the Fee Letters or in the
other Loan Documents. 
 Section 10.11 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES UNDER THIS
AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 
 Section 10.12
Submission To Jurisdiction; Waivers. The Borrower hereby irrevocably and unconditionally:

 87 

 
or vote or consent of, any Lender, or any affiliate of any Lender that is a party to any Specified Hedge Agreement) take such actions as shall be required to
release its security interest in any Collateral being Disposed of in such Disposition, and to release any guarantee obligations under any Loan Document of any Person being Disposed of in such Disposition, to the extent necessary to permit

outstanding, upon request of the Borrower, the Collateral Agent shall (without notice to, or vote or consent of, any Lender, or any affiliate of any Lender that is a party to any Specified Hedge Agreement) take such actions as shall be required to

to equitably reflect such Accounting Change with the desired result that the criteria for evaluating the Borrower’s financial condition shall be the same after such Accounting Change as if such Accounting Change had not been made. Until such
time as such an amendment shall have been executed and delivered by the Borrower, the Administrative Agent and the Required Lenders, all financial covenants, standards and terms in this Agreement shall continue to be calculated or construed as if
such Accounting Change had not occurred. “Accounting Change” refers to any change in accounting principles required by the promulgation of any rule, regulation, pronouncement or opinion by the Financial Accounting Standards
Board of the American Institute of Certified Public Accountants or, if applicable, the SEC.
