instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of

(subject to Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee, the Company and, if applicable, the Guarantors, if made in the manner provided in this Section.

Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any different part of such principal amount.

any series entitled to give or take any request, demand, authorization, direction, notice, consent, waiver or other Act provided or permitted by this Indenture to be given or taken by Holders of Securities of such series, but the Company shall have
no obligation to do so. With regard to any record date set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date (or their duly appointed agents), and only such Persons, shall be entitled to

validity of any action taken in reliance upon such waiver.

Indenture Act shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act that may be so modified or excluded, the provision of the Trust Indenture Act shall be deemed to apply to this Indenture as
so modified or excluded, as the case may be.

Law. 
 THIS INDENTURE, THE SECURITIES AND THE SECURITIES GUARANTEE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK. 
 Section 1.16. Legal Holidays.

of Payment, then (notwithstanding any other provision of this Indenture or of the Securities or, if applicable, the Securities Guarantee (other than a provision of the Securities of any series or, if applicable, the Securities Guarantee that
specifically states that such provision shall apply in lieu of this Section 1.16)) payment of interest or principal and any premium need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at
such Place of Payment with the same force and effect as if made on the Interest Payment Date or Redemption Date, or at the Stated Maturity, and if payment is so made, no interest shall accrue for the period from and after such Interest Payment Date,

Securities of all series or all series affected by a particular action at the time Outstanding and, at such time, there are Outstanding Securities of any affected series which are denominated in a coin, currency or currencies other than Dollars

Bank of New York as of the most recent available date, or quotations or rates of exchange from one or more major banks in The City of New York or in the country of issue of the currency in question, which for purposes of Euros shall be
Brussels, Belgium, or such other quotations or rates of exchange as the Trustee shall deem appropriate. The provisions of this paragraph shall apply in determining the equivalent principal amount in respect of Securities of a series denominated in a
currency other than Dollars in connection with any action taken by Holders of Securities pursuant to the terms of this Indenture. 
 All decisions and determinations of the Trustee regarding the Market Exchange Rate or any alternative determination provided for in the preceding paragraph shall be in its sole discretion and shall, in

principal of or interest on the Securities of any series (the “Required Currency”) into a currency in which a judgment will be rendered (the “Judgment Currency”), the rate of exchange used shall be the rate at which in accordance
with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the day on which final unappealable judgment is entered, unless such day is not a Banking Day, then, to the extent
permitted by applicable law, the rate of exchange used shall be the rate at which in accordance with normal banking procedures the Trustee could purchase in The City of New York the Required Currency with the Judgment Currency on the Banking Day
next preceding the day on which final unappealable judgment is entered and (b) its obligations under this Indenture to make payments in the Required Currency (i) shall not be discharged or satisfied by any tender, or any recovery pursuant
to any judgment (regardless of whether entered in accordance with subclause (a)), in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the actual receipt, by the payee, of the full
amount of the Required Currency expressed to be payable in respect of such payments, (ii) shall be enforceable as an alternative or additional cause of action for the purpose of recovering in the Required Currency the amount, if any, by which
such actual receipt shall fall short of the full amount of the Required Currency so expressed to be payable and (iii) shall not be affected by judgment being obtained for any other sum due under this Indenture. 

Section 1.19. Language of Notices, Etc.

Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment or penalty or otherwise, it being expressly understood that all such liability is hereby expressly waived and released as a condition of,

respect of the payment of the principal of and interest, if any, on the Securities of this series shall terminate.] 
 The Indenture permits,
with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company [If applicable, insert—and the Guarantors] and the rights of the Holders of the Securities of each
series to be affected under the Indenture at any time by the Company [If applicable, insert—and the Guarantors] and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding
of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such
series, to waive compliance by the Company [If applicable, insert—and the Guarantors] with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder
of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, regardless of whether
notation of such consent or waiver is made upon this Security.

Securities shall be executed on behalf of the Company by its Chairman of the Board, its Chief Executive Officer, its President, its Chief Financial Officer or any of its Vice Presidents and need not be attested. The signature of any of these
officers on the Securities may be manual or facsimile. Any Securities Guarantee endorsed on the Securities shall be executed on behalf of the applicable Guarantor by its Chairman of the Board, its Chief Executive Officer, its President, its Chief
Financial Officer or any of its Vice Presidents and need not be attested. The signature of any of these officers on any endorsement of the Securities Guarantee may be manual or facsimile. 

Securities and any endorsement of a Securities Guarantee bearing the manual or facsimile signatures of individuals who were at any time
the proper officers of the Company or a Guarantor, as the case may be, shall bind the Company or such Guarantor, as the case may be, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication
and delivery of such Securities or did not hold such offices at the date of such Securities. 
 At any time and from time to
time after the execution and delivery of this Indenture, the Company may deliver Securities of any series executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such
Securities, and the Trustee in accordance with the Company Order shall authenticate and deliver such Securities; provided, however, that in the case of Securities offered in a Periodic Offering, the Trustee shall authenticate and
deliver such Securities from time to time in accordance with such other procedures (including, without limitation, the receipt by the Trustee of oral or electronic instructions from the Company or its duly authorized agents, thereafter promptly
confirmed in writing) acceptable to the Trustee as may be specified by or pursuant to a Company Order delivered to the Trustee prior to the time of the first authentication of Securities of such series. If the forms or terms of the Securities of the
series have been established in or pursuant to one or more Board Resolutions as permitted by Section 2.1 and Section 3.1, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to
such Securities, the Trustee 

  
 26 









 
shall be entitled to receive such documents as it may reasonably request. The Trustee shall also be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying
upon, an Opinion of Counsel stating: 
 (a) if the form or forms of such Securities has been established in or
pursuant to a Board Resolution as permitted by Section 2.1, that each such form has been established in conformity with the provisions of this Indenture; 
 (b) if the terms of such Securities have been, or in the case of Securities of a series offered in a Periodic Offering will be, established in or pursuant to a Board Resolution as permitted by
Section 3.1, that such terms have been, or in the case of Securities of a series offered in a Periodic Offering will be, established in conformity with the provisions of this Indenture, subject, in the case of Securities of a series offered in
a Periodic Offering, to any conditions specified in such Opinion of Counsel; and 
 (c) that such Securities when
authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions and assumptions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company and, if
applicable, the Guarantors, enforceable in accordance with their terms, subject to the following limitations: (i) bankruptcy, insolvency, moratorium, reorganization, liquidation, fraudulent conveyance or transfer and other similar laws of
general applicability relating to or affecting the enforcement of creditors’ rights, or to general equity principles, (ii) the availability of equitable remedies being subject to the discretion of the court to which application therefor is
made; and (iii) such other usual and customary matters as shall be specified in such Opinion of Counsel. 
 If such form or forms or terms
have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s own rights, duties or immunities under the Securities and this
Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the provisions of
Section 3.1 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the Officer’s Certificate otherwise required pursuant to Section 3.1 or the
Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the time of authentication of each Security of such series if such documents are delivered at or prior to the authentication upon original
issuance of the first Security of such series to be issued. 
 With respect to Securities of a series offered in a Periodic
Offering, the Trustee may rely, as to the authorization by the Company of any of such Securities, on the form or forms and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and the other
documents delivered pursuant to Section 2.1 and Section 3.1 and this Section, as applicable, in connection with the first authentication of Securities of such series. 

Each Security shall be dated the date of its authentication. 
 No Security, nor any Securities Guarantee endorsed thereon, shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a
certificate of authentication substantially in the form provided for herein executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been 

  
 27 









 
authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 3.9, for
all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 Section 3.4. Temporary Securities. 
 Pending the preparation of
Definitive Securities of any series, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized
denomination, substantially of the tenor of the Definitive Securities in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as
evidenced by their execution of such Securities. 
 If temporary Securities of any series are issued, the Company will cause
Definitive Securities of that series to be prepared without unreasonable delay. After the preparation of Definitive Securities of such series, the temporary Securities of such series shall be exchangeable for Definitive Securities of such series
upon surrender of the temporary Securities of such series at the office or agency of the Company in a Place of Payment for that series, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Securities of any
series the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Definitive Securities of the same series and tenor of authorized denominations. Until so exchanged the temporary
Securities of any series shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities of such series. 

Section 3.5. Registration, Registration of Transfer and Exchange. 
 The Company shall cause to be kept at the office or agency of the Company in a Place of Payment required by Section 10.2 a register (the register maintained in such office being herein sometimes
referred to as the “Security Register”) in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities and of transfers of Securities. The Trustee is hereby appointed as
the initial “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided, and its corporate trust office, which, at the date hereof, is located at 5555 San Felipe, Suite 1150, Houston, Texas
77056, is the initial office or agency where the Securities Register will be maintained. The Company may at any time replace such Security Registrar, change such office or agency or act as its own Security Registrar. The Company will give prompt
written notice to the Trustee of any change of the Security Registrar or of the location of such office or agency. 
 Upon
surrender for registration of transfer of any Security of any series at the office or agency maintained pursuant to Section 10.2 for such purpose, the Company and, if applicable, the Guarantors shall execute, and the Trustee shall authenticate
and deliver, in the name of the designated transferee or transferees, one or more new Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of the same series and tenor, of any authorized
denominations and of a like aggregate principal amount. 

  
 28 









 At the option of the Holder, Securities of any series (except a Global Security) may be
exchanged for other Securities of the same series and tenor, of any authorized denominations and of a like aggregate principal amount, upon surrender of the Securities to be exchanged at such office or agency. Whenever any Securities are so
surrendered for exchange, the Company and, if applicable, the Guarantors shall execute and the Trustee shall authenticate and deliver, the Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, which
the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company and, if applicable, the Guarantors evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or
exchange. 
 Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the
Company or the Trustee) be duly endorsed, or be accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed, by the Holder thereof or his attorney duly authorized in writing.

 No service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require
payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 3.4, Section 9.6 or
Section 11.7 not involving any transfer. 
 The Company shall not be required (a) to issue, register the transfer of
or exchange Securities of any series during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of Securities of that series selected for redemption under Section 11.3 and ending at the
close of business on the day of such mailing, or (b) to register the transfer of or exchange any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part. 

Notwithstanding any other provisions of this Indenture and except as otherwise specified with respect to any particular series of
Securities as contemplated by Section 3.1, a Global Security representing all or a portion of the Securities of a series may not be transferred, except as a whole by the Depositary for such series to a nominee of such Depositary or by a nominee
of such Depositary to such Depositary or another nominee of such Depositary or by such Depositary or any such nominee to a successor Depositary for such series or a nominee of such successor Depositary. Every Security authenticated and delivered
upon registration of, transfer of, or in exchange for or in lieu of, a Global Security shall be a Global Security except as provided in the two paragraphs immediately following. 

If at any time the Depositary for any Securities of a series represented by one or more Global Securities notifies the Company that it is
unwilling or unable to continue as Depositary for such Securities or if at any time the Depositary for such Securities shall no longer be eligible to continue as Depositary under Section 3.1 or ceases to be a clearing agency registered under
the Exchange Act, the Company shall appoint a successor Depositary with respect to such Securities. If a successor Depositary for such Securities is not appointed by the Company within 90 days after the Company receives such notice or becomes aware
of such ineligibility, the Company’s election pursuant to Section 3.1 that such Securities be represented by one or more Global Securities shall no longer be effective and the Company and, if applicable, the Guarantors will execute and the
Trustee, upon receipt of a Company Order for the authentication and delivery of Definitive Securities of such series, will authenticate and deliver, Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the
Guarantors, of such series in definitive registered form without coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such Securities in exchange
for such Global Security or Securities registered in the names of such Persons as the Depositary shall direct. 

  
 29 









 The Company may at any time and in its sole discretion determine that the Securities of any
series issued in the form of one or more Global Securities shall no longer be represented by a Global Security or Securities. In such event, the Company and, if applicable, the Guarantors will execute and the Trustee, upon receipt of a Company Order
for the authentication and delivery of Definitive Securities of such series, will authenticate and deliver, Securities, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of such series in definitive
registered form without coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of the Global Security or Securities representing such Securities in exchange for such Global Security or Securities
registered in the names of such Persons as the Depositary shall direct. 
 If specified by the Company pursuant to
Section 3.1 with respect to Securities represented by a Global Security, the Depositary for such Global Security may surrender such Global Security in exchange in whole or in part for Securities of the same series and tenor in definitive
registered form on such terms as are acceptable to the Company, the Trustee and such Depositary. Thereupon, the Company and, if applicable, the Guarantors shall execute, and the Trustee, upon receipt of a Company Order for the authentication and
delivery of Securities in definitive registered form, shall authenticate and deliver, without service charge: 

(i) to the Person specified by such Depositary a new Security or Securities, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, of the same series and tenor, of any authorized denominations as requested by such Person, in an aggregate principal amount equal to and in exchange for such Person’s beneficial interest in
the Global Security; and 
 (ii) to such Depositary a new Global Security, with an endorsement of the Securities
Guarantee, if applicable, executed by the Guarantors, in a denomination equal to the difference, if any, between the principal amount of the surrendered Global Security and the aggregate principal amount of Securities authenticated and delivered
pursuant to clause (i) above. 
 Every Person who takes or holds any beneficial interest in a Global Security agrees that:

 (A) the Company, the Guarantors (if applicable) and the Trustee may deal with the Depositary as sole owner of
the Global Security and as the authorized representative of such Person; 
 (B) such Person’s rights in the
Global Security shall be exercised only through the Depositary and shall be limited to those established by law and agreement between such Person and the Depositary and/or direct and indirect participants of the Depositary; 

(C) the Depositary and its participants make book-entry transfers of beneficial ownership among, and receive and transmit
distributions of the principal of (and premium, if any) and interest on the Global Securities to, such Persons in accordance with their own procedures; and 
 (D) none of the Company, the Guarantors (if applicable), the Trustee, nor any agent of any of them will have any responsibility or liability for any aspect of the records relating to or payments made on
account of beneficial ownership interests of a Global Security or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

 Section 3.6. Mutilated, Destroyed, Lost and Stolen Securities. 

If any mutilated Security is surrendered to the Trustee, together with, in proper cases, such security or indemnity as may be required by
the Company, the Guarantors (if applicable) or the Trustee to save each of them and any agent of any of them harmless, the Company and, if applicable, the Guarantors shall execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security, with an endorsement of the Securities Guarantee, if applicable, executed by the Guarantors, of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

If there shall be delivered to the Company, the Guarantors (if applicable) and the Trustee (a) evidence to their satisfaction of the
destruction, loss or theft of any Security and (b) such security or indemnity as may be required by them to save each of them and any agent of any of them harmless, then, in the absence of notice to the Company or the Trustee that such Security
has been acquired by a bona fide purchaser, the Company and, if applicable, the Guarantors shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security, with an endorsement of
the Securities Guarantee, if applicable, executed by the Guarantors, of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Security, pay such Security. 
 Upon the issuance of any new Security under this
Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

 Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall
constitute an original additional contractual obligation of the Company and, if applicable, the Guarantors, regardless of whether the destroyed, lost or stolen Security shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other Securities of that series duly issued hereunder. 

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Securities. 
 Section 3.7. Payment of Interest; Interest Rights
Preserved. 
 Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities,
interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of
business on the Regular Record Date for such interest. 
 Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein called “Defaulted Interest”) shall forthwith cease to be payable to the Holder on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below: 

  
 31 









 (a) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following
manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an
amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit 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 Company of such Special Record Date and, in
the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at his
address as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest
shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following
clause (b). 
 (b) The Company may make payment of any Defaulted Interest on the Securities of any series in any
other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the
proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee. 
 Subject to the foregoing
provisions of this Section, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by
such other Security. 
 Section 3.8. Persons Deemed Owners. 
 Except as otherwise provided as contemplated by Section 3.1 with respect to any series of Securities, prior to due presentment of a Security for registration of transfer, the Company, the Trustee
and, if applicable, the Guarantors and any agent thereof may treat the Person in whose name such Security is registered as the owner of such Security for the purpose of receiving payment of principal of and any premium and (subject to
Section 3.5 and Section 3.7) any interest on such Security and for all other purposes whatsoever, regardless of whether such Security be overdue, and none of the Company, the Trustee nor, if applicable, the Guarantors nor any agent of any
of them shall be affected by notice to the contrary. 
 No holder of any beneficial interest in any Global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect to such Global Security, and such Depositary may be treated by the Company, the Trustee, and, if applicable, the Guarantors and any agent of thereof as the owner of such
Global Security for all purposes whatsoever. 

  
 32 









 Section 3.9. Cancellation. 

All Securities surrendered for payment, redemption, registration of transfer or exchange or for credit against any sinking fund payment
shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly canceled by it. The Company may at any time deliver to the Trustee for cancellation any Securities previously authenticated and delivered
hereunder which the Company may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the Trustee) for cancellation any Securities previously authenticated hereunder which the Company has not
issued and sold, and all Securities so delivered shall be promptly canceled by the Trustee. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this
Indenture. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary practices, and the Trustee shall thereafter deliver to the Company a certificate with respect to such disposition from time to time upon
written request. 
 Section 3.10. Computation of Interest. 
 Except as otherwise specified as contemplated by Section 3.1 for Securities of any series, interest on the Securities of each series shall be computed on the basis of a year of twelve 30-day months.

 Section 3.11. CUSIP or CINS Numbers. 
 The Company in issuing the Securities may use “CUSIP” or “CINS” numbers (if then generally in use, and in addition to the other identification numbers printed on the Securities), and,
if so, the Trustee shall use “CUSIP” or “CINS” numbers in notices of redemption as a convenience to Holders; provided, however, that any such notice may state that no representation is made as to the correctness of
such “CUSIP” or “CINS” numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such “CUSIP” or “CINS” numbers. 

ARTICLE FOUR 
 SATISFACTION AND DISCHARGE 
 Section 4.1. Satisfaction and Discharge of
Indenture. 
 This Indenture shall cease to be of further effect and will be discharged with respect to the Securities of any
series (except as to any surviving rights of registration of transfer or exchange of Securities and certain rights of the Trustee, in each case, herein expressly provided for), and the Trustee, upon Company Request and at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of this Indenture with respect to such Securities, when:

thereafter repaid to the Company or discharged from such trust, as provided in Section 10.3) have been delivered to the Trustee for cancellation; or

under arrangements satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company, in the case of (ii)(A), (B) or (C) above, has deposited or caused to be deposited with the Trustee as trust funds in trust for such purpose an amount sufficient to pay and
discharge the entire indebtedness on such Securities not theretofore delivered to the Trustee for cancellation, for principal (and premium, if any) and interest to the date of such deposit (in the case of Securities which have become due and
payable) or to the Stated Maturity or Redemption Date, as the case may be, together with instructions from the Company irrevocably directing the Trustee to apply such funds to the payment thereof at maturity or redemption, as the case may be;

 (b) the Company has paid or caused to be paid all other sums payable hereunder by the Company with respect to
such Securities; and 
 (c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion

the Trustee pursuant to clause (a) of this Section, the obligations of the Company and the Trustee under Section 4.2, Section 6.6, Section 10.2 and the last paragraph of Section 10.3 shall survive. 

  
 34 









 Section 4.2. Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 10.3, all money deposited with the Trustee pursuant to Section 4.1
shall be held in trust and applied by it, in accordance with the provisions of the Securities and this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto, of the principal and any premium and interest for the payment of which such money has been deposited with the Trustee. 
 ARTICLE FIVE 
 REMEDIES 

Section 5.1. Events of Default. 
 “Event of Default,” wherever used herein with respect to Securities of any series, means any one of the following events (whatever the reason for such Event of Default and whether it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 

(a) default in the payment of any interest upon any Security of that series when it becomes due and payable, 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 Security of that series at its Maturity; or 
 (c) default in the performance, or
breach, of any covenant set forth in Article Ten in this Indenture (other than a covenant a default in the performance of which or the breach of which is elsewhere in this Section specifically dealt with or which has expressly been included in
this Indenture solely for the benefit of series of Securities other than that series), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee or to
the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a
“Notice of Default” hereunder; or 
 (d) default in the performance, or breach, of any covenant in this
Indenture (other than a covenant in Article Ten or any other covenant a default in the performance of which or the breach of which is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture
solely for the benefit of series of Securities other than that series), and continuance of such default or breach for a period of 120 days after there has been given, by registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Securities of that series a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a “Notice of
Default” hereunder; or 
 (e) the Company pursuant to or within the meaning of any Bankruptcy Law
(i) commences a voluntary case, (ii) consents to the entry of any 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

 (f) a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that (i) is for relief against the Company in an involuntary case, (ii) appoints a Custodian of the Company or for all or substantially all of its property, or (iii) orders the liquidation of the Company; and the order
or decree remains unstayed and in effect for 60 consecutive days; or 
 (g) default in the deposit of any sinking
fund payment when due; or 
 (h) any other Event of Default provided with respect to Securities of that series in
accordance with Section 3.1. 
 Section 5.2. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case
the Trustee or the Holders of 25% in aggregate principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal
amount as may be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately due and payable. Notwithstanding the foregoing, if an Event of Default specified in clause (e) or (f) of Section 5.1 occurs, the Securities of any series at the time
Outstanding shall be due and payable immediately without further action or notice. 
 At any time after such a declaration of
acceleration with respect to Securities of any series has been made and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article Five provided, the Holders of a majority in
principal amount of the Outstanding Securities of that series, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if: 

(a) the Company or, if applicable, one or more of the Guarantors has paid or deposited with the Trustee a sum sufficient
to pay: 
 (i) all overdue interest on all Securities of that series; 

(ii) the principal of (and premium, if any, on) any Securities of that series which have become due otherwise than by such
declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities; 
 (iii) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities; and 

(iv) all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel; and 
 (b) all Events of Default with respect to Securities of
that series, other than the non-payment of the principal of Securities of that series which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.13. 

  
 36 









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

Section 5.3. Collection of Indebtedness and Suits for Enforcement by Trustee. 

The Company covenants that if: 
 (a) default is made in the payment of any installment of interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days; or 

(b) default is made in the payment of the principal of (or premium, if any, on) any Security at the Maturity thereof,

 the Company will, upon demand of the Trustee, pay to it, for the benefit of the Holders of such Securities, the whole amount then due and
payable on such Securities for principal and any premium and interest and, to the extent that payment of such interest shall be legally enforceable, interest on any overdue principal and any premium and on any overdue interest, at the rate or rates
prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel. 
 If the Company fails to pay such amounts forthwith upon such demand, the Trustee, in its own name and
as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or, if applicable, the
Guarantors or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or, if applicable, the Guarantors or any other obligor upon such
Securities, wherever situated. 
 If an Event of Default with respect to Securities of any series occurs and is continuing, the
Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such
rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy. 
 Section 5.4. Trustee May File Proofs of Claim. 
 In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or, if applicable, any Guarantor or any other obligor upon the Securities,
their property or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any
demand on the Company or, if applicable, the Guarantors for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise: 

(a) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in
respect of the Securities and to file such other papers or documents 

  
 37

and counsel) and of the Holders allowed in such judicial proceeding; and 
 (b) to collect and receive any moneys
or other property payable or deliverable on any such claims and to distribute the same; 
 and any custodian, receiver, assignee, trustee,
liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, if the Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.7. 

No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any
Holder any plan of reorganization, compromise, arrangement, adjustment or composition affecting the Securities or, if applicable, the Securities Guarantee or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the
claim of any Holder in any such proceeding; provided, however, that the Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar official and be a member of a creditors’ or other similar
committee. 
 Section 5.5. Trustee May Enforce Claims Without Possession of Securities. 

All rights of action and claims under this Indenture or the Securities may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or the production thereof in any proceeding relating thereto, and any such proceeding instituted by the Trustee shall be brought in its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Securities in respect of which such judgment has been
recovered. 
 Section 5.6. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article Five shall be applied in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on
account of principal or any premium or interest, upon presentation of the Securities and the notation thereon of the payment if only partially paid and upon surrender thereof if fully paid: 

FIRST: To the payment of all amounts due the Trustee under Section 6.7; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Securities
in respect of which or for the benefit of which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on such Securities for principal and any premium and interest, respectively;
and 
 THIRD: The balance, if any, to the Company. 

  
 38 









 Section 5.7. Limitation on Suits. 

No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this
Indenture (including, if applicable, the Securities Guarantee), or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless: 
 (a) such Holder has previously given written notice to the Trustee of a continuing Event of Default with respect to the Securities of that series; 

(b) the Holders of not less than 25% in principal amount of the Outstanding Securities of that series shall have made
written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (c) such Holder or Holders have offered to the Trustee reasonable indemnity against the costs, expenses and liabilities to be incurred in compliance with such request; 

(d) the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any
such proceeding; and 
 (e) no direction inconsistent with such written request has been given to the Trustee
during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood
and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or prejudice the rights of any other of such Holders, or to obtain or to
seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and ratable benefit of all such Holders. 

Section 5.8. Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and
unconditional (subject to Section 3.7 and Section 9.2), to receive payment of the principal of and any premium and interest on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder. 
 Section 5.9. Restoration of Rights and Remedies. 
 If the Trustee or
any Holder has instituted any proceeding to enforce any right or remedy under this Indenture and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder, then and in every
such case, subject to any determination in such proceeding, the Company, the Guarantors, the Trustee and the Holders shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the
Trustee and the Holders shall continue as though no such proceeding had been instituted. 

  
 39 









 Section 5.10. Rights and Remedies Cumulative. 

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last
paragraph of Section 3.6, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent
assertion or employment of any other appropriate right or remedy. 
 Section 5.11. Delay or Omission Not Waiver. 

To fullest extent permitted by applicable law, no delay or omission of the Trustee or of any Holder of any Securities to exercise any
right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article Five or by law to the Trustee
or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 Section 5.12. Control by Holders. 
 The Holders of not less than a
majority in principal amount of the Outstanding Securities of any series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on
the Trustee, with respect to the Securities of such series; provided, however, that: 
 (a) such
direction shall not be in conflict with any rule of law or with this Indenture; 
 (b) the Trustee may take any
other action deemed proper by the Trustee which is not inconsistent with such direction; and 
 (c) subject to
the provisions of Section 6.1, the Trustee shall have the right to decline to follow any such direction if the Trustee in good faith shall determine that the proceeding so directed would involve the Trustee in personal liability. 

Section 5.13. Waiver of Past Defaults. 
 By written notice to the Company and the Trustee, the Holders of not less than a majority in principal amount of the Outstanding Securities of any series may on behalf of the Holders of all the Securities
of such series waive any past default hereunder with respect to such series and its consequences, except: 

  
 40 









 (a) a continuing default in the payment of the principal of or any premium
or interest on any Security of such series; or 
 (b) a default in respect of a covenant or provision hereof
which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected. 
 Upon any such waiver, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture, but no such waiver shall extend
to any subsequent or other default or impair any right consequent thereon. 
 Section 5.14. Undertaking for Costs. 

All parties to this Indenture agree, and each Holder of any 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, suffered or omitted by it as Trustee, the filing by any party litigant, other
than the Trustee, in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys’ fees, 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 5.14 shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by
any Holder, or group of Holders, holding in the aggregate more than 10% in principal amount of the Outstanding Securities of any series, or to any suit instituted by any Holder for the enforcement of the payment of the principal of (or premium, if
any) or interest on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date). 
 Section 5.15. Waiver of Stay or Extension Laws. 
 Each of the Company
and the Guarantors covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance of this Indenture; and each of the Company and the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

Trustee; and 
 (ii) in the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth
of the statements and the correctness of the opinions expressed therein, upon 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 they conform to the requirements of this Indenture. 

(b) In case an Event of Default has occurred and is continuing, 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.

its own negligent failure to act, or its own bad faith or willful misconduct, except that: 
 (i) this Subsection
shall not be construed to limit the effect of Subsection (a) of this Section; 
 (ii) the Trustee shall not
be liable for any 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;

available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture with respect to the Securities of such series; and 
 (iv) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it. 

(d) Regardless of whether therein expressly so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section.

however, that, except in the case of a Default in the payment of the principal of or any premium or interest on any Security of such series or in the payment of any sinking fund installment with respect to Securities of such series, the
Trustee may withhold from Holders of Securities notice of any continuing Default or Event of Default if a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Securities
of such series; and, provided, further, that in the case of any Default of the character specified in Section 5.1(c) with respect to Securities of such series, no such notice to Holders shall be given until at least 90 days after

Officer’s Certificate may be signed by any person authorized to sign an Officer’s Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded;

in acting as a Paying Agent or Security Registrar hereunder;

Trustee, and such notice references the Securities and this Indenture; and 
 (k) anything in this Indenture
notwithstanding, in no event shall the Trustee be liable for any special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including but not limited to loss of profit), even if the Company has been advised as to
the likelihood of such loss or damage and regardless of the form of action. 
 Section 6.4. Not Responsible for Recitals or Issuance of
Securities. 
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication,

 Section 6.7. Compensation and Reimbursement. 
 The Company agrees:

 (a) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder
(which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust);

resignation or removal of the Trustee and the termination or satisfaction and discharge of this Indenture and the Legal Defeasance of the Securities. 

  
 45 









 Section 6.8. Disqualification; Conflicting Interests. 

Reference is made to Section 310(b) of the Trust Indenture Act. There shall be excluded from the operation of Section 310(b)(1)
of the Trust Indenture Act this Indenture with respect to the Securities of more than one series. 
 Section 6.9. Corporate Trustee
Required; Eligibility. 
 There shall at all times be a Trustee hereunder which shall be a corporation organized and doing
business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to exercise corporate trust powers, having a combined capital and surplus required by the Trust Indenture Act, subject
to supervision or examination by Federal or State authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. The Trustee shall not be an obligor upon the Securities or an
Affiliate thereof. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article Six. 

Section 6.10. Resignation and Removal; Appointment of Successor. 

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

(d) If at any time: 
 (i) the Trustee shall fail to comply with Section 310(b) of the Trust Indenture Act after written request therefor by the Company or by any Holder who has been a bona fide Holder of a Security for at
least six months; or 
 (ii) the Trustee shall cease to be eligible under Section 6.9 and shall fail to
resign after written request therefor by the Company or by any such Holder; or

incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of
rehabilitation, conservation or liquidation, 

  
 46 









 then, in any such case, (A) the Company by a Board Resolution may remove the Trustee
with respect to all Securities, or (B) subject to Section 5.14, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 
 (e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Securities of one or more series, the
Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one
or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of Section 6.11. If, within one year after such
resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of
such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 6.11, become the successor
Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or
the Holders and accepted appointment in the manner required by Section 6.11, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 (f) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the
Securities of any series to all Holders of Securities of such series in the manner provided in Section 1.7. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its
Corporate Trust Office. 
 Section 6.11. Acceptance of Appointment by Successor. 

(a) In case of the appointment hereunder of a successor Trustee with respect to all Securities, the successor Trustee so
appointed shall execute, acknowledge and deliver to the Company, the Guarantors (if applicable) and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company, any Guarantor (if applicable) or the
successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. 

  
 47 









 (b) In case of the appointment hereunder of a successor Trustee with respect
to the Securities of one or more (but not all) series, the Company, the Guarantors (if applicable), the retiring Trustee and each successor Trustee with respect to the Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment and which (i) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights,
powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (ii) if the retiring Trustee is not retiring with respect to all Securities,
shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not
retiring shall continue to be vested in the retiring Trustee, and (iii) 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 Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and
each such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of
such successor Trustee relates; but, on request of the Company, any Guarantor (if applicable) or any successor Trustee, such retiring Trustee, upon payment of its charges, shall execute and deliver an instrument transferring to such successor
Trustee all the rights, powers and trusts of the retiring Trustee with respect to the Securities of the series to which the appointment of such successor relates and shall duly assign, transfer and deliver to such successor Trustee all property and
money held by such retiring Trustee hereunder with respect to the Securities of such series. 
 (c) Upon request
of any such successor Trustee, the Company and, if applicable, the Guarantors shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts referred to in
paragraph (a) or (b) of this Section, as the case may be. 
 (d) No successor Trustee shall accept its
appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article and the Trust Indenture Act. 
 Section 6.12. Merger, Conversion, Consolidation or Succession to Business. 
 Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall
be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this
Article Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

 Section 6.13. Preferential Collection of Claims Against Company. 

Reference is made to Section 311 of the Trust Indenture Act. For purposes of Section 311(b) of the Trust Indenture Act:

 (a) the term “cash transaction” means any transaction in which full payment for goods or securities
sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand; 

(b) the term “self-liquidating paper” means any draft, bill of exchange, acceptance or obligation which is made,
drawn, negotiated or incurred by the Company or, if applicable, any Guarantor for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing
title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee
simultaneously with the creation of the creditor relationship with the Company or, if applicable, such Guarantor arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation. 

Section 6.14. Appointment of Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents with respect to one or more series of Securities which shall be authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 3.6, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed
to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company
and shall at all times be a corporation organized and doing business under the laws of the United States of America, any State thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital
and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said
supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so
published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

 Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any
corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the
Authenticating Agent. 

  
 49 









 An Authenticating Agent may resign at any time by giving written notice thereof to the
Trustee and to the Company and, if applicable, the Guarantors. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company and, if applicable, the
Guarantors. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and, if applicable, the Guarantors and shall mail written notice of such appointment by first-class mail, postage prepaid, to all Holders of Securities of the series with respect to which
such Authenticating Agent will serve, as their names and addresses appear in the Security Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its
predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section. 

Except with respect to an Authenticating Agent appointed at the request of the Company or, if applicable, the Guarantors, the Trustee
agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section 6.14, and the Trustee shall be entitled to be reimbursed by the Company or, if applicable, the Guarantors for such
payments, subject to the provisions of Section 6.7. 
 If an appointment with respect to one or more series is made
pursuant to this Section 6.14, the Securities of such series may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form: 

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

 ARTICLE SEVEN 
 HOLDERS’ LISTS AND REPORTS BY TRUSTEE AND COMPANY 
 Section 7.1.
Company to Furnish Trustee Names and Addresses of Holders. 
 The Company will furnish or cause to be furnished to the
Trustee: 
 (a) semi-annually, not more than 15 days after each Regular Record Date for a series of Securities, a
list for such series of Securities, in such form as the Trustee may reasonably require, of the names and addresses of the Holders of Securities of such series as of such Regular Record Date; and 

  
 50 









 (b) at such other times as the Trustee may request in writing, within 30
days after the receipt by the Company of any such request, a list of similar form and content as of a date not more than 15 days prior to the time such list is furnished; 
 provided, however, that if and so long as the Trustee shall be the Security Registrar, no such list need be furnished with respect to such series of Securities. 

Section 7.2. Preservation of Information; Communications to Holders. 

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, the names and addresses of Holders
contained in the most recent list furnished to the Trustee as provided in Section 7.1 and the names and addresses of Holders received by the Trustee in its capacity as Security Registrar. The Trustee may destroy any list furnished to it as
provided in Section 7.1 upon receipt of a new list so furnished. 
 (b) If three or more Holders (herein
referred to as “applicants”) apply in writing to the Trustee, and furnish to the Trustee reasonable proof that each such applicant has owned a Security for a period of at least six months preceding the date of such application, and such
application states that the applicants desire to communicate with other Holders with respect to their rights under this Indenture or under the Securities and is accompanied by a copy of the form of proxy or other communication which such applicants
propose to transmit, then the Trustee shall, within five business days after the receipt of such application, at its election, either: 
 (i) afford such applicants access to the information preserved at the time by the Trustee in accordance with Section 7.2(a); or 

(ii) inform such applicants as to the approximate number of Holders whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with Section 7.2(a), and as to the approximate cost of mailing to such Holders the form of proxy or other communication, if any, specified in such application. 

If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written
request of such applicants, mail to each Holder whose name and address appear in the information preserved at the time by the Trustee in accordance with Section 7.2(a) a copy of the form of proxy or other communication which is specified in
such request, with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within five days after such tender the Trustee shall mail
to such applicants and file with the SEC, together with a copy of the material to be 
 mailed, a written
statement to the effect that, in the opinion of the Trustee, such mailing would be contrary to the best interest of the Holders or would be in violation of applicable law. Such written statement shall specify the basis of such opinion. If the SEC,
after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after the entry of an order sustaining one or more of such objections, the SEC
shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their application. 

  
 51 









 (c) Every Holder of Securities, by receiving and holding the same, agrees
with the Company, the Guarantors (if applicable) and the Trustee that none of the Company, the Guarantors (if applicable) nor the Trustee nor any agent of any of them shall be held accountable by reason of the disclosure of any such information as
to the names and addresses of the Holders in accordance with Section 7.2(b), regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a
request made under Section 7.2(b). 
 Section 7.3. Reports by Trustee. 

Any Trustee’s report required pursuant to Section 313(a) of the Trust Indenture Act shall be dated as of May 15, and shall
be transmitted within 60 days after May 15 of each year (but in all events at intervals of not more than 12 months), commencing with the year 20__, by mail to all Holders, as their names and addresses appear in the Security Register. A copy of
each such report shall, at the time of such transmission to Holders, be filed by the Trustee with each stock exchange upon which any Securities are listed, with the SEC and with the Company. The Company will notify the Trustee when any Securities
are listed on any stock exchange. 
 Section 7.4. Reports by Company. 

So long as clauses (1), (2) and (3) of Section 314(a) of the Trust Indenture Act (or any successor provisions of law) are
applicable to this Indenture, the Company shall: 
 (a) file with the Trustee, within 15 days after the Company
files the same with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may from time to time by rules and regulations prescribe) which the Company
may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; or, if the Company is not required to file information, documents or reports pursuant to either of said Sections, then it shall file with the
Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, such of the supplementary and periodic information, documents and reports which may be required pursuant to Section 13 of the Exchange Act in
respect of a security listed and registered on a national securities exchange as may be prescribed from time to time in such rules and regulations; 
 (b) file with the Trustee and the SEC, in accordance with rules and regulations prescribed from time to time by the SEC, such additional information, documents and reports with respect to compliance by
the Company with the conditions and covenants of this Indenture as may be required from time to time by such rules and regulations; and 
 (c) transmit by mail to all Holders, as their names and addresses appear in the Security Register, within 30 days after the filing thereof with the Trustee, such summaries of any information, documents
and reports required to be filed by the Company pursuant to clauses (a) and (b) of this Section as may be required by rules and regulations prescribed from time to time by the SEC.

conveyance, transfer, lease or other disposition is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the
Company herein, and thereafter, except in the case of a lease, the predecessor Company and each of the Guarantors shall be relieved of all obligations and covenants under this Indenture and the Securities. 

ARTICLE NINE

(e) to secure the Securities of any series; or 

(f) to add to the covenants of the Company such further covenants, restrictions, conditions or provisions as the Company
shall consider to be appropriate for the benefit of the Holders of all or any series of Securities (and if such covenants, restrictions, conditions or provisions are to be for the benefit of less than all series of Securities, stating that such
covenants are expressly being included solely for the benefit of such series), to make the occurrence, or the occurrence and continuance, of a Default in any such additional covenants, restrictions, conditions or provisions an Event of Default
permitting the enforcement of all or any of the several remedies provided in this Indenture as herein set forth, or to surrender any right or power herein conferred upon the Company; provided, that in respect of any such additional covenant,
restriction, condition or provision such amendment or 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), may provide for an
immediate enforcement upon such an Event of Default, may limit the remedies available to the Trustee upon such an Event of Default or may limit the right of the Holders of a majority in aggregate principal amount of the Securities of such series to
waive such an Event of Default; or 
 (g) to make any change to any provision of this Indenture that does not
adversely affect the rights or interests of any Holder of Securities; or

registrable as to principal, and with or without interest coupons; or 
 (k) to change or eliminate any of the
provisions of this Indenture; provided that any such change or elimination shall become effective only when there is no Security Outstanding of any series created prior to the execution of such amendment or supplemental indenture that is
entitled to the benefit of such provision; or 

  
 54 









 (l) to establish the form or terms of Securities of any series as permitted
by Section 2.1 and Section 3.1, including to reopen any series of any Securities as permitted under Section 3.1; or 
 (m) to evidence and provide for the acceptance of appointment hereunder by a successor Trustee with respect to the 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, pursuant to the requirements of Section 6.11(b); or 

(n) to conform the text of this Indenture (and/or any supplemental indenture) or any debt securities issued thereunder to
any provision of a description of such debt securities appearing in a prospectus, prospectus supplement, offering memorandum or offering circular to the extent that such provision appears on its face to have been intended to be a verbatim recitation
of a provision of this Indenture (and/or any supplemental indenture) or any debt securities issued thereunder; or 
 (o) to modify, eliminate or add to the provisions of this Indenture to such extent as shall be necessary to effect the qualification of this Indenture under the Trust Indenture Act or under any similar
federal statute subsequently enacted, and to add to this Indenture such other provisions as may be expressly required under the Trust Indenture Act. 
 Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amendment or supplemental indenture, and upon receipt by the Trustee of the documents described in
Section 6.3 hereof, the Trustee will join with the Company and any Guarantor in the execution of any such amendment or supplemental indenture, to make any further appropriate agreements and stipulations that may be therein contained and to
accept the conveyance, transfer, assignment, mortgage, charge or pledge of any property thereunder, but the Trustee shall not be obligated to enter into any such amendment or supplemental indenture that affects the Trustee’s own rights, duties
or immunities under this Indenture or otherwise. 
 Section 9.2. With Consent of Holders. 

The Company and the Trustee may amend or supplement this Indenture, the Securities Guarantees and the Securities with the consent of the
Holders of a majority in aggregate principal amount of the Outstanding Securities of each series of Securities affected by such amendment or supplemental indenture, with each such series voting as a separate class (including, without limitation,
consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities) and, subject to Section 5.8 and Section 5.13 hereof, any existing Default or Event of Default or compliance with any provision of this
Indenture, the Securities Guarantees or the Securities may be waived with respect to each series of Securities with the consent of the Holders of a majority in principal amount of the Outstanding Securities of such series voting as a separate class
(including consents obtained in connection with a purchase of, or tender offer or exchange offer for, Securities). 
 Upon the
request of the Company accompanied by a Board Resolution authorizing the execution of any such amendment or supplemental indenture, and upon the filing with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of
Securities as aforesaid, and upon receipt by the Trustee of the documents described in Section 6.3 hereof, the Trustee will join with the Company and the 

  
 55 









 Guarantors in the execution of such amendment or supplemental indenture unless such amendment or
supplemental indenture directly affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to, enter into such amendment or supplemental
Indenture. 
 It is not necessary for the consent of the Holders of Securities under this Section 9.2 to approve the
particular form of any proposed amendment, supplement or waiver, but it is sufficient if such consent approves the substance of the proposed amendment, supplement or waiver. 
 After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company will mail to the Holders of Securities affected thereby, with a copy to the Trustee, a notice briefly
describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amendment, supplemental indenture or waiver. Subject to
Section 5.8 and Section 5.13 hereof, the application of or compliance with, either generally or in any particular instance, of any provision of this Indenture, the Securities or the Securities Guarantees may be waived as to each series of
Securities by the Holders of a majority in aggregate principal amount of the Outstanding Securities of such series voting as a separate class (including consents obtained in connection with a purchase of, or tender offer or exchange offer for,
Securities). However, without the consent of each Holder affected, an amendment, supplement or waiver under this Section 9.2 may not (with respect to any Securities held by a non-consenting Holder): 

(a) change the Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or
reduce the principal amount thereof or the rate of interest thereon or any premium payable upon the redemption thereof, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 5.2, or change the coin or currency in which any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment
on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date); or 

(b) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of the Holders of
which is required for any such amendment or supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with certain provisions of this Indenture or certain defaults hereunder and their consequences
provided for in this Indenture; or 
 (c) modify any of the provisions of Section 5.8 or Section 5.13;
or 
 (d) waive a redemption payment with respect to any Security; provided, however, that any purchase or
repurchase of Securities shall not be deemed a redemption of the Securities; or 
 (e) release any Guarantor from
any of its obligations under its Securities Guarantee or this Indenture, except in accordance with the terms of this Indenture (as amended or supplemented); or 
 (f) make any change in the foregoing amendment and waiver provisions, except to increase any percentage provided for therein or to provide that certain other provisions of this Indenture cannot be
modified or waived without the consent of the Holder of each Outstanding Security affected thereby. 

  
 56 









 An amendment or supplemental indenture that changes or eliminates any covenant or other
provision of this Indenture that has expressly been included solely for the benefit of one or more particular series of Securities, or that modifies the rights of the Holders of Securities of such series with respect to such covenant or other
provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series. 
 Section 9.3.
Execution of Amendments and Supplemental Indentures. 
 In executing, or accepting the additional trusts created by, any
amendment or supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 6.1) shall be fully protected in relying upon,
an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such amendment or supplemental indenture which
affects the Trustee’s own rights, duties or immunities under this Indenture or otherwise. 
 Section 9.4. Effect of Amendments and
Supplemental Indentures. 
 Upon the execution of any amendment or supplemental indenture under this Article Nine, this
Indenture shall be modified in accordance therewith, and such amendment or supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Securities theretofore or thereafter authenticated and delivered hereunder
shall be bound thereby. 
 Section 9.5. Conformity with Trust Indenture Act. 

Every amendment or supplemental indenture executed pursuant to this Article Nine shall conform to the requirements of the Trust
Indenture Act as then in effect. 
 Section 9.6. Reference in Securities to Amendments or Supplemental Indentures. 

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

 ARTICLE TEN 

COVENANTS 

Section 10.1. Payment of Principal, Premium and Interest. 
 The Company covenants and agrees for the benefit of each series of Securities that it will duly and punctually pay the principal of and any premium and interest on the Securities of that series in
accordance with the terms of the Securities and this Indenture. 
 Section 10.2. Maintenance of Office or Agency. 

The Company will maintain in the United States an office or agency (which may be an office of the Trustee or Registrar or agent of the
Trustee or Registrar) where Securities of each series may be presented or surrendered for payment and surrendered for registration of transfer or exchange and where notices and demands to or upon the Company in respect of the Securities of that
series and this Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Company shall fail to maintain any such required office
or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the Trustee. 

The Company may also from time to time designate one or more other offices or agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time rescind such designations. The Company will give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such
other office or agency. 
 Except as otherwise specified with respect to a series of Securities as contemplated by
Section 3.1, the Company hereby initially designates the office of the Trustee located at 5555 San Felipe, Suite 1150, Houston, Texas 77056, as the Company’s office or agency for each such purpose for each series of Securities. 

Section 10.3. Money for Securities Payments to Be Held in Trust. 
 If the Company shall at any time act as its own Paying Agent, with respect to any series of Securities, it will, on or before each due date of the principal of and any premium or interest on any of the
Securities of that series, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and any premium and interest so becoming due until such sums shall be paid to such Persons or otherwise
disposed of as herein provided and will promptly notify the Trustee of its action or failure so to act. 
 Whenever the Company
shall have one or more Paying Agents for any series of Securities, it will, prior to each due date of the principal of and any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay the principal
and any premium or interest so becoming due, such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company will promptly notify the 

  
 58 









 Trustee of its action or failure so to act. For purposes of this Section 10.3, should a due date for
principal of and any premium or interest on, or sinking fund payment with respect to any series of Securities not be on a Business Day, such payment shall be due on the next Business Day without any interest for the period from the due date until
such Business Day. 
 The Company will cause each Paying Agent for any series of Securities other than the Trustee to execute
and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will: 

(a) hold all sums held by it for the payment of the principal of and any premium or interest on Securities of that series
in trust for the benefit of the Persons entitled thereto until such sums shall be paid to such Persons or otherwise disposed of as herein provided; 
 (b) give the Trustee notice of any Default by the Company (or any other obligor upon the Securities of that series) in the making of any payment of principal and any premium or interest on the Securities
of that series; and 
 (c) at any time during the continuance of any such Default, upon the written request of
the Trustee, forthwith pay to the Trustee all sums so held in trust by such Paying Agent. 
 The Company and, if applicable, the
Guarantors may at any time, for the purpose of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such
Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from
all further liability with respect to such money. 
 Subject to any applicable escheat or abandoned property laws, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and any premium or interest on any Security of any series and remaining unclaimed for one year after such principal, premium or
interest has become due and payable shall be paid to the Company on Company Request, or (if then held by the Company) shall be discharged from such trust; and the Holder of such Security shall thereafter, as an unsecured general creditor, look only
to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains
unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 10.4. Existence. 
 Subject to Article Eight, the Company and, if any Securities of a series to which Article Fourteen has been made applicable are Outstanding, each Guarantor will do or cause to be done all things
necessary to preserve and keep in full force and effect its existence, rights (charter and statutory) and franchises; provided, however, that the Company and, if applicable, each Guarantor shall not be required to preserve any such
right or franchise if the Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Company or such Guarantor, as the case may be. 

  
 59 









 Section 10.5. Statement by Officers as to Default. 

Annually, within 150 days after the close of each fiscal year beginning with the first fiscal year during which one or more series of
Securities are Outstanding, the Company and, if any Securities of a series to which Article Fourteen has been made applicable are Outstanding, each Guarantor will deliver to the Trustee a brief certificate (which need not include the statements
set forth in Section 1.3) from the principal executive officer, principal financial officer or principal accounting officer of the Company and, if applicable, such Guarantor as to his or her knowledge of the Company’s or such
Guarantor’s, as the case may be, compliance (without regard to any period of grace or requirement of notice provided herein) with all conditions and covenants under this Indenture and, if the Company or such Guarantor, as the case may be, shall
be in Default, specifying all such Defaults and the nature and status thereof of which such officer has knowledge. 

ARTICLE ELEVEN

 Section 11.1. Applicability of Article.

 Securities of any series which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms
and (except as otherwise specified as contemplated by Section 3.1 for Securities of any series) in accordance with this Article Eleven. 
 Section 11.2. Election to Redeem; Notice to Trustee. 
 The election of
the Company to redeem any Securities shall be evidenced by a Board Resolution. In case of any redemption at the election of the Company of less than all the Securities of any series, the Company shall, at least 15 days prior to the last date for the
giving of notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date and of the principal amount of Securities of such series to be redeemed and, if applicable, of the tenor
of the Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an
election of the Company that is subject to a condition specified in the terms of the Securities of the series to be redeemed, the Company shall furnish the Trustee with an Officer’s Certificate evidencing compliance with such restriction or
condition. 
 Section 11.3. Selection by Trustee of Securities to Be Redeemed. 

If less than all the Securities of any series are to be redeemed (unless all of the Securities of such series and of a specified tenor are
to be redeemed), the particular Securities to be redeemed shall be selected not more than 45 days prior to the Redemption Date by the Trustee, from the Outstanding 

  
 60 









 Securities of such series not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of that series or any integral multiple thereof) of the principal amount of Securities of such
series of a denomination larger than the minimum authorized denomination for Securities of that series. 
 The Trustee shall
promptly notify the Company in writing of the Securities selected for redemption and, in the case of any Securities selected for partial redemption, the principal amount thereof to be redeemed. If the Securities of any series to be redeemed consist
of Securities having different dates on which the principal is payable or different rates of interest, or different methods by which interest may be determined or have any other different tenor or terms, then the Company may, by written notice to
the Trustee, direct that the Securities of such series to be redeemed shall be selected from among the groups of such Securities having specified tenor or terms and the Trustee shall thereafter select the particular Securities to be redeemed in the
manner set forth in the preceding paragraph from among the group of such Securities so specified. 
 For all purposes of this
Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities
which has been or is to be redeemed. 
 Section 11.4. Notice of Redemption. 

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

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

(c) if less than all the Outstanding Securities of any series are to be redeemed, the identification (and, in the case of
partial redemption, the principal amounts) of the particular Securities to be redeemed; 
 (d) that on the
Redemption Date the Redemption Price will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date; 

(e) the place or places where such Securities are to be surrendered for payment of the Redemption Price; and 

(f) that the redemption is for a sinking fund, if such is the case. 

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

  
 61 









 Section 11.5. Deposit of Redemption Price. 

Prior to any Redemption Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 10.3) an amount of money sufficient to pay the Redemption Price of, and (except if the Redemption Date shall be an Interest Payment Date) accrued interest on, all the Securities
which are to be redeemed on that date. 
 Section 11.6. Securities Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Securities so to be redeemed shall, on the Redemption Date, become due and
payable at the Redemption Price therein specified, and from and after such date (unless the Company shall default in the payment of the Redemption Price and accrued interest) such Securities shall cease to bear interest. Upon surrender of any such
Security for redemption in accordance with said notice, such Security shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date; provided, however, that unless otherwise specified with
respect to Securities of any series as contemplated in Section 3.1, installments of interest the Stated Maturity of which is on or prior to the Redemption Date shall be payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant record dates according to their terms and the provisions of Section 3.7. 
 If any Security called for redemption shall not be so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption Date at the rate
prescribed therefor in the Security. 
 Section 11.7. Securities Redeemed in Part. 

Any Security which is to be redeemed only in part shall be surrendered at a Place of Payment therefor (with, if the Company or the Trustee
so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), and the Company shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the same series and tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and
in exchange for the unredeemed portion of the principal of the Security so surrendered.

 ARTICLE TWELVE 

SINKING FUNDS 

Section 12.1. Applicability of Article. 
 The provisions of this Article Twelve shall be applicable to any sinking fund for the retirement of Securities of a series except as otherwise specified as contemplated by Section 3.1 for
Securities of such series. 
 The minimum amount of any sinking fund payment provided for by the terms of Securities of any
series is herein referred to as a “mandatory sinking fund payment,” and any payment in excess of such minimum amount provided for by the terms of Securities of any series is herein referred to as an “optional sinking fund
payment.” If provided for by the terms of Securities of any series, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 12.2. Each sinking fund payment shall be applied to the redemption of
Securities of any series as provided for by the terms of Securities of such series. 
 Section 12.2. Satisfaction of Sinking Fund
Payments with Securities. 
 The Company (a) may deliver Outstanding Securities of a series (other than any previously
called for redemption) and (b) may apply as a credit Securities of a series which have been redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund
payments pursuant to the terms of such Securities, in each case in satisfaction of all or any part of any sinking fund payment with respect to the Securities of such series required to be made pursuant to the terms of such Securities as provided for
by the terms of such series; provided that such Securities have not been previously so credited. Such Securities shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for
redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly. 
 Section 12.3.
Redemption of Securities for Sinking Fund. 
 Not less than 45 days prior to each sinking fund payment date for any series
of Securities (unless a shorter period shall be satisfactory to the Trustee), the Company will deliver to the Trustee an Officer’s Certificate specifying the amount of the next ensuing sinking fund payment for that series pursuant to the terms
of that series, the portion thereof, if any, which is to be satisfied by payment of cash and the portion 
 thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series pursuant to Section 12.2 and stating the basis for such credit and that such Securities have not been previously so credited, and will also deliver to the Trustee
any Securities to be so delivered. Not less than 30 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 11.3 and cause
notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 11.4. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Section 11.6 and Section 11.7.

 ARTICLE THIRTEEN 

DEFEASANCE 

Section 13.1. Option to Effect Legal Defeasance or Covenant Defeasance. 

The Company may, at the option of its Board of Directors evidenced by a Board Resolution, and at any time, elect to have either
Section 13.2 or Section 13.3 hereof be applied to all outstanding Securities upon compliance with the conditions set forth below in this Article Thirteen. 
 Section 13.2. Legal Defeasance and Discharge. 
 Upon the Company’s
exercise under Section 13.1 hereof of the option applicable to this Section 13.2, the Company and each of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 13.4 hereof, be deemed to have been
discharged from their obligations with respect to all outstanding Securities (including the Securities Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal
Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Debt represented by the outstanding Securities (including the Securities Guarantees), which will thereafter be deemed to be
“outstanding” only for the purposes of Section 13.5 hereof and the other sections of this Indenture referred to in clauses (a) and (b) below, and to have satisfied all their other obligations under such Securities, the
Securities Guarantees and this Indenture (and the Trustee, on demand of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which will survive until otherwise terminated or
discharged hereunder: 
 (a) the rights of Holders of Outstanding Securities to receive payments in respect of
the principal of, or interest or premium, if any, on, such Securities when such payments are due from the trust referred to in Section 13.4 hereof; 
 (b) the Company’s obligations with respect to such Securities under Section 3.4, Section 3.5, Section 3.6, Section 10.2 and Section 10.3 hereof; 

(c) the rights, powers, trusts, duties and immunities of the Trustee hereunder and the Company’s and the
Guarantors’ obligations in connection therewith; and 
 (d) this Article Thirteen. 

Subject to compliance with this Article Thirteen, the Company may exercise its option under this Section 13.2 notwithstanding
the prior exercise of its option under Section 13.3 hereof. 
 Section 13.3. Covenant Defeasance. 

Upon the Company’s exercise under Section 13.1 hereof of the option applicable to this Section 13.3, the Company and each
of the Guarantors will, subject to the satisfaction of the conditions set forth in Section 13.4 hereof, be released from each of their obligations under the covenants contained in Section 7.4, Section 8.1 and Section 10.4 hereof
as well as any Additional Defeasible Provisions (such release and termination hereinafter referred to as “Covenant Defeasance”), and the Securities will thereafter be deemed not “outstanding” for the purposes of any direction,
waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but will continue to be deemed “outstanding” for all other purposes hereunder (it being understood that such
Securities will not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Securities and Securities Guarantees, the Company and the Guarantors may fail to comply with and
will have no liability in respect of any term, 

  
 64 









 
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such
covenant to any other provision herein or in any other document and such failure to comply will not constitute a Default or an Event of Default under Section 5.1 hereof, but, except as specified above, the remainder of this Indenture and such
Securities and Securities Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 13.1 hereof of the option applicable to this Section 13.3 hereof, subject to the satisfaction of the conditions
set forth in Section 13.4 hereof, any Event of Default that constitutes an Additional Defeasible Provision will no longer constitute an Event of Default. 
 Section 13.4. Conditions to Legal or Covenant Defeasance. 
 In order to
exercise either Legal Defeasance or Covenant Defeasance under either Section 13.2 or Section 13.3 hereof: 
 (a) the Company must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Securities, cash in U.S. dollars, non-callable U.S. Government Obligations, or a combination of
cash in U.S. dollars and non-callable U.S. Government Obligations, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, appraisal firm, or firm of independent public accountants, to pay the principal of,
and interest and premium, if any, on, the Outstanding Securities on the stated date for payment thereof or on the applicable redemption date, as the case may be, and the Company must specify whether the Securities are being defeased to such stated
date for payment or to a particular redemption date; 
 (b) in the case of an election under Section 13.2
hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that: 
 (i) the Company has
received from, or there has been published by, the Internal Revenue Service a ruling; or 
 (ii) since the Issue
Date, there has been a change in the applicable federal income tax law, 
 in either case to the effect that, and based thereon
such Opinion of Counsel will confirm that, the Holders of the Outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred; 
 (c) in the case of an election under Section 13.3 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that the Holders of the Outstanding Securities will not recognize
income, gain or loss for federal income tax purposes as a result of such Covenant Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant
Defeasance had not occurred; 
 (d) no Default or Event of Default shall have occurred and be continuing on the
date of such deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit); 

  
 65 









 (e) the deposit must not result in a breach or violation of, or constitute a
default under, any other instrument to which the Company or any Guarantor is a party or by which the Company or any Guarantor is bound; 
 (f) such Legal Defeasance or Covenant Defeasance must not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which the
Company or any of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound; 
 (g)
the Company must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Securities over the other creditors of the Company with the intent of defeating,
hindering, delaying or defrauding any other creditors of the Company or others; 
 (h) the Company must deliver
to the Trustee an Officer’s Certificate stating that all conditions precedent set forth in clauses (a) through (f) of this Section 13.4 have been complied with; and 

(i) the Company must deliver to the Trustee an Opinion of Counsel (which Opinion of Counsel may be subject to customary
assumptions, qualifications and exclusions) stating that all conditions precedent set forth in clauses (b), (c) and (f) of this Section 13.4 have been complied with. 
 Section 13.5. Deposited Money and U.S. Government Obligations to be Held in Trust, Other Miscellaneous Provisions. 
 Subject to Section 13.6 hereof, all money and non-callable U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for
purposes of this Section 13.5, the “Trustee”) pursuant to Section 13.4 hereof in respect of the Outstanding Securities will be held in trust and applied by the Trustee, in accordance with the provisions of such Securities and
this Indenture, to the payment, either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders of such Securities of all sums due and to become due thereon in respect of
principal, premium, if any, and interest, but such money need not be segregated from other funds except to the extent required by law. 
 The Company will pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to
Section 13.4 hereof or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Securities. 

Notwithstanding anything in this Article Thirteen to the contrary, the Trustee will deliver or pay to the Company from time to time
upon the request of the Company any money or non-callable U.S. Government Obligations held by it as provided in Section 13.4 hereof which, in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public
accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 13.4(a) hereof), are in excess of the amount thereof that would then be required to be deposited to effect an
equivalent Legal Defeasance or Covenant Defeasance. 

  
 66 









 Section 13.6. Repayment. 

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of or
premium, if any, or interest on any Security and remaining unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall be paid to the Company on its request or (if then held by the Company) will be
discharged from such trust; and the Holder of such Security will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of
the Company as trustee thereof, will thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Company cause to be published once, in The New York
Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30 days from the date of such notification or publication, any unclaimed
balance of such money then remaining will be repaid to the Company. 
 Section 13.7. Reinstatement. 

If the Trustee or Paying Agent is unable to apply any United States dollars or non-callable U.S. Government Obligations in accordance with
Section 13.2 or Section 13.3 hereof, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Company’s and the
Guarantors’ obligations under this Indenture and the Securities and the Securities Guarantees will be revived and reinstated as though no deposit had occurred pursuant to Section 13.2 or Section 13.3 hereof until such time as the
Trustee or Paying Agent is permitted to apply all such money in accordance with Section 13.2 or Section 13.3 hereof, as the case may be; provided, however, that, if the Company makes any payment of principal of or premium, if any,
or interest on any Note following the reinstatement of its obligations, the Company will be subrogated to the rights of the Holders of such Securities to receive such payment from the money held by the Trustee or Paying Agent. 

ARTICLE FOURTEEN 
 GUARANTEE OF SECURITIES 
 Section 14.1. Securities Guarantee.

 (a) Subject to the other provisions of this Article Fourteen, each of the Guarantors hereby jointly and
severally guarantees to each Holder of a Security of each series to which this Article Fourteen has been made applicable as provided in Section 3.1(t) (the Securities of such series being referred to herein as the “Guaranteed
Securities”) (which Security has been authenticated and delivered by the Trustee), and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture, the Guaranteed Securities, or the
obligations of the Company hereunder or thereunder, that: 
 (i) the principal of and premium, if any, and
interest on the Guaranteed Securities will be promptly paid in full when due, whether at maturity, or by acceleration, redemption or otherwise, and interest on the overdue principal of and interest on the


  
 67 









 
Guaranteed Securities, if any, if lawful, and all other obligations of the Company to the Holders of Guaranteed Securities, or the Trustee hereunder or thereunder, will be promptly paid in full
or performed, all in accordance with the terms hereof and thereof; and 
 (ii) in case of any extension of time
of payment or renewal of any Guaranteed Securities or any of such other obligations, that same will be promptly paid in full when due or performed in accordance with the terms of the extension or renewal, whether at stated maturity, by acceleration
or otherwise. 
 Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the
Guarantors will be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection. 

(b) To the extent permissible under applicable law, the obligations of the Guarantors under this Securities Guarantee are
unconditional, irrespective of the validity, regularity or enforceability of the Guaranteed Securities or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Guaranteed Securities with respect to
any provisions hereof or thereof, the recovery of any judgment against the Company, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. To the extent
permitted by applicable law, each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any right to require a proceeding first against the Company,
protest, notice and all demands whatsoever and covenants that this Securities Guarantee will not be discharged except by complete performance of the obligations contained in the Guaranteed Securities and this Indenture. 

(c) If any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any
custodian, trustee, liquidator or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such Holder, this Securities Guarantee, to the extent theretofore discharged, will be
reinstated in full force and effect. 
 (d) Each Guarantor agrees that it will not be entitled to any right of
subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, to the extent permitted by applicable law, as between the
Guarantors, on the one hand, and the Holders of Guaranteed Securities and the Trustee, on the other hand, (i) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of this
Securities Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration of such obligations as
provided in Article Five hereof, such obligations (regardless of whether due and payable) will forthwith become due and payable by the Guarantors for the purpose of this Securities Guarantee. The Guarantors will have the right to seek
contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Securities Guarantee. 

  
 68 









 Section 14.2. Limitation on Guarantor Liability. 

Each Guarantor, and by its acceptance of Guaranteed Securities, each Holder thereof, hereby confirms that it is the intention of all such
parties that the Securities 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 Securities Guarantee. To effectuate the foregoing intention, the Trustee, to the extent permitted under applicable law, the Holders and each Guarantor 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 Fourteen, result in the obligations of such Guarantor under its Securities Guarantee
not constituting a fraudulent transfer or conveyance. 
 Section 14.3. Execution and Delivery of Securities Guarantee Notation.

 To evidence its Securities Guarantee set forth in Section 14.1 hereof, each Guarantor hereby agrees that a notation of
such Securities Guarantee substantially in the form set forth in Section 2.3 or established in or pursuant to a Board Resolution or in an indenture supplemental hereto, in accordance with the provisions of Section 2.1, will be endorsed by
an officer of such Guarantor on each Guaranteed Security authenticated and delivered by the Trustee and that this Indenture will be executed on behalf of such Guarantor by one of its officers. 

Each Guarantor hereby agrees that its Securities Guarantee set forth in Section 14.1 hereof will remain in full force and effect
notwithstanding any failure to endorse on each Guaranteed Security a notation of such Securities Guarantee. 
 If an officer
whose signature is on this Indenture or on the Securities Guarantee no longer holds that office at the time the Trustee authenticates the Guaranteed Security on which a Securities Guarantee is endorsed, the Securities Guarantee will be valid
nevertheless. 
 The delivery of any Guaranteed Security by the Trustee, after the authentication thereof hereunder, will
constitute due delivery of the Securities Guarantee of such Guaranteed Security set forth in this Indenture on behalf of the Guarantors.
