SECTION 104 Acts of Holders; Record Dates. 
 Whenever in this Indenture it is provided that the Holders of a specified percentage in aggregate principal amount of the Securities of any or all series may take action (including the making of any
demand or request, the giving of any direction, notice, consent or waiver or the taking of any other action) the fact that at the time of taking any such action the Holders of such specified percentage have joined therein may be evidenced
(a) by any instrument or any number of instruments of similar tenor executed by Holders in person or by agent or proxy appointed in writing, (b) by the record of the Holders voting in favor thereof at any meeting of Holders duly called and
held in accordance with procedures approved by the Trustee, (c) by a combination of such instrument or instruments and any such record of such a meeting of Holders or (d) in the case of Securities evidenced by a Global Security, by any
electronic transmission or other message, whether or not in written format, that complies with the Depositary’s applicable procedures. Such evidence (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the
“Act” of the relevant Holders. Proof of execution of any such instrument or of a writing appointing any such agent or proxy shall be sufficient for any purpose of this Indenture and (subject to Section 601) conclusive in favor
of the Trustee and the Company, if made in the manner provided in this Section. 
 The fact and date of the execution by any
Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing
such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

Security Register. 
 Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any
Security shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by
the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

 The Company may set any day as a record date for the purpose of determining the Holders of
Outstanding Securities of any series entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Securities of
such series, provided that the Company may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If
any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of the relevant series on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders
after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Securities of such series on such record date.
Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall
automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Securities of the
relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration
Date to be given to the Trustee in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 
 The Trustee may set any day as a record date for the purpose of determining the Holders of Outstanding Securities of any series entitled to join in the giving or making of (i) any Notice of Default,
(ii) any declaration of acceleration referred to in Section 502, (iii) any request to institute proceedings referred to in Section 507(2) or (iv) any direction referred to in Section 512, in each case with respect to
Securities of such series. If any record date is set pursuant to this paragraph, the Holders of Outstanding Securities of such series on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or
direction, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of
Outstanding Securities of such series on such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite
principal amount of Outstanding Securities of the relevant series on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date,
the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Securities of the relevant series in the manner set forth in Section 106. 

With respect to any record date set pursuant to this Section, the party hereto which sets such record dates may designate any day as the
“Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the proposed new Expiration Date is given to the other party hereto
in writing, and to each Holder of Securities of the relevant series in the manner set forth in Section 106, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect to any record date set pursuant to
this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to change the Expiration Date as provided
in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Security may do so with regard to all or any part of the principal amount of such
Security or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 
 SECTION 105 Notices, Etc., to Trustee and Company. 
 Any request,
demand, authorization, direction, notice, consent, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with: 

(1) the Trustee by any Holder or by the Company or any Subsidiary Guarantor shall be sufficient for every purpose hereunder if made,
given, furnished or filed in writing in the English language to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Department; or 

  
 7 

 (2) the Company or any Subsidiary Guarantor by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, in the case of the Company addressed to it at the address of its principal office
specified in the first paragraph of this instrument or at any other address previously furnished in writing to the Trustee by the Company and, in the case of any Subsidiary Guarantor, to it at the address of the Company’s principal office
specified in the first paragraph of this instrument, Attention: Chief Financial Officer, or at any other address previously furnished in writing to the Trustee by such Subsidiary Guarantor. 

SECTION 106 Notice to Holders; Waiver. 
 Where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing in the English language and mailed,
first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such
notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Where
this Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such notification as shall be made with the approval
of the Trustee shall constitute a sufficient notification for every purpose hereunder. 
 SECTION 107 Conflict with Trust
Indenture Act. 
 If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act
which is required under such Act to be a part of and govern this Indenture, the latter provision shall control. If any provision of this Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded,
the latter provision shall be deemed to apply to this Indenture as so modified or to be excluded, as the case may be.

108 Effect of Headings and Table of Contents. 
 The Article and Section headings herein and the Table of Contents
are for convenience only and shall not affect the construction hereof. 
 SECTION 109 Successors and Assigns.

 All covenants and agreements in this Indenture by the Company and any Subsidiary Guarantor shall bind their respective
successors and assigns, whether so expressed or not. 
 SECTION 110 Separability Clause. 

In case any provision in this Indenture, the Securities or the Subsidiary Guarantees shall be invalid, illegal or unenforceable, the
validity, legality and enforce ability of the remaining provisions shall not in any way be affected or impaired thereby. 

SECTION 111 Benefits of Indenture. 
 Nothing in this Indenture, the Securities or the Subsidiary Guarantees, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any
benefit or any legal or equitable right, remedy or claim under this Indenture. 
 SECTION 112 Governing Law.

 SECTION 113 Legal Holidays. 

In any case where any Interest Payment Date, Redemption Date, purchase date or Stated Maturity of any Security shall not be a Business
Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities (other than a provision of any Security which specifically states that such provision shall apply in lieu of this Section)) payment of
interest or principal (and premium, if any) 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,
Redemption Date or purchase date, or at the Stated Maturity. 
 SECTION 114 No Recourse Against Others.

 No director, officer, employee, incorporator, stockholder, member, partner or trustee of the Company or any Subsidiary
Guarantor, as such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the Securities, this Indenture or any Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations
or their creation. By accepting a Security, each Holder shall be deemed to have waived and released all such liability. The waiver and release shall be a part of the consideration for the issue of the Securities.

called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to
                            , or registered assigns, the principal sum of
                             Dollars on
                             [if the Security is to bear interest prior to Maturity, insert
— , and to pay interest thereon from                              or from the most recent
Interest Payment Date to which interest has been paid or duly provided for, semi-annually on
                             and
                             in each year, commencing

                % per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they
are paid or made available for payment, and such interest shall be payable on demand. The interest so payable, and 

  
 9 

 
punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Security (or one or more Predecessor Securities)
is registered at the close of business on the Regular Record Date for such interest, which shall be the              or
             (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will

payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture]. 

[If the Security is not to bear interest prior to Maturity, insert — The principal of this Security shall not bear interest except
in the case of a default in payment of principal upon acceleration, upon redemption or at Stated Maturity and in such case the overdue principal and any overdue premium shall bear interest at the rate of
            % per annum (to the extent that the payment of such interest shall be legally enforceable), from the dates such amounts are due until they are paid or made
available for payment. Interest on any overdue principal or premium shall be payable on demand. Any such interest on overdue principal or premium which is not paid on demand shall bear interest at the rate of
            % per annum (to the extent that the payment of such interest on interest shall be legally enforceable), from the date of such demand until the amount so demanded
is paid or made available for payment. Interest on any overdue interest shall be payable on demand.] 
 Payment of the principal
of (and premium, if any) and [if applicable, insert — any such] interest on this Security will be made at the office or agency of the Company maintained for that purpose in
            , in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts; provided, however,
that at the option of the Company payment of interest may be made by check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register. 

Reference is hereby made to the further provisions of this Security set forth on the reverse hereof, which further provisions shall for
all purposes have the same effect as if set forth at this place.

be released from its Subsidiary Guarantee upon compliance with certain conditions.] 
 [If applicable, insert — The
Indenture contains provisions for Defeasance at any time of [the entire indebtedness of this Security] [or] [certain restrictive covenants and Events of Default with respect to this Security] [, in each case] upon compliance with certain conditions
set forth in the Indenture.] 
 [If the Security is not an Original Issue Discount Security, insert — If an Event of
Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.] 

[If the Security is an Original Issue Discount Security, insert — If an Event of Default with respect to Securities of this series
shall occur and be continuing, an amount of principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture. Such amount shall be equal to — insert formula for determining
the amount. Upon payment (i) of the amount of principal so declared due and payable and (ii) of interest on any overdue principal, premium and interest (in each case to the extent that the payment of such interest shall be legally
enforceable), all of the Company’s obligations in respect of the payment of the principal of and premium 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 and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company 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 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, whether or not notation of such consent or
waiver is made upon this Security. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Security
shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a
continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the Trustee reasonable security or indemnity, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time
Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by
the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein [if applicable, insert — or the right to convert this Security in
accordance with its terms]. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed [insert if
applicable — and to convert such Security in accordance with its terms]. 
 As provided in the Indenture and subject to
certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and
any premium and interest on this Security are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

  
 12 

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

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentment of this
Security for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue,
and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

 (21) any other terms of the series (which terms shall not be inconsistent with the provisions of this Indenture, except as permitted by Section 901(5)). 

All Securities of any one series shall be substantially identical except as to denomination and except as may otherwise be provided in or
pursuant to the Board Resolution referred to above and (subject to Section 303) set forth, or determined in the manner provided, in the Officers’ Certificate referred to above or in any such indenture supplemental hereto. 

If any of the terms of the series are established by action taken pursuant to a Board Resolution, a copy of an appropriate record of such
action shall be certified by the Secretary or an Assistant Secretary of the Company and delivered to the Trustee at or prior to the delivery of the Officers’ Certificate setting forth the terms of the series. 

The Securities of each series shall have the benefit of the Subsidiary Guarantees unless the Company elects otherwise upon the
establishment of a series pursuant to this Section 301. 
 SECTION 302 Denominations. 

The Securities of each series shall be issuable only in registered form without coupons and only in such denominations as shall be
specified as contemplated by Section 301. In the absence of any such specified denomination with respect to the Securities of any series, the Securities of such series shall be issuable in denominations of $1,000 and any integral multiple
thereof. 
 SECTION 303 Execution, Authentication, Delivery and Dating. 

The Securities shall be executed on behalf of the Company by its Chairman of the Board of Directors, its Vice Chairman of the Board of
Directors, its President or one of its Vice Presidents. If its corporate seal is reproduced thereon, then it shall be attested by its Secretary or one of its Assistant Secretaries. The signature of any of these officers on the Securities may be
manual or facsimile. 

  
 17 

 Securities bearing the manual or facsimile signatures of individuals who were at any time
the proper officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of
such Securities. 
 At any time and from time to time after the execution and delivery of this Indenture, the Company may
deliver Securities of any series executed by the Company and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees executed as provided in Section 1303 by the Subsidiary Guarantors 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. If the form or terms of the Securities of the series have been
established by or pursuant to one or more Board Resolutions as permitted by Sections 201 and 301, in authenticating such Securities, and accepting the additional responsibilities under this Indenture in relation to such Securities, the Trustee
shall be entitled to receive, and (subject to Section 601) shall be fully protected in relying upon, an Opinion of Counsel stating,
 (1) if the form of such Securities has been established by or pursuant to Board Resolution as permitted by Section 201, that such form has been established in conformity with the provisions of this
Indenture; 
 (2) if the terms of such Securities have been established by or pursuant to Board Resolution as permitted by
Section 301, that such terms have been established in conformity with the provisions of this Indenture; and 
 (3) that
such Securities, when authenticated and delivered by the Trustee and issued by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company, and,
if applicable, the notations of Subsidiary Guarantees endorsed thereon will constitute valid and legally binding obligations of the Subsidiary Guarantors, enforceable in accordance with their terms, subject to bankruptcy, insolvency, fraudulent
transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles. 
 If such form or terms have been so established, the Trustee shall not be required to authenticate such Securities if the issue of such Securities pursuant to this Indenture will affect the Trustee’s
own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee. 
 Notwithstanding the provisions of Section 301 and of the preceding paragraph, if all Securities of a series are not to be originally issued at one time, it shall not be necessary to deliver the
Officers’ Certificate otherwise required pursuant to Section 301 or the Company Order and Opinion of Counsel otherwise required pursuant to such preceding paragraph at or prior to the authentication of each Security of such series if such
documents are delivered at or prior to the authentication upon original issuance of the first Security of such series to be issued. 
 Each Security shall be dated the date of its authentication. 
 No Security or
Subsidiary Guarantee 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, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Security shall
have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall deliver such Security to the Trustee for cancellation as provided in Section 309, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of this Indenture. 
 SECTION 304 Temporary Securities. 
 Pending the preparation of
definitive Securities 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 and, if applicable, having endorsed thereon the notations of Subsidiary Guarantees in lieu of which they are issued and with such appropriate insertions, omissions, substitutions
and other variations as the officers executing such Securities and, if applicable, notations of Subsidiary Guarantees may determine, as evidenced by their execution of such Securities and notations of Subsidiary Guarantees. 

  
 18 

 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 one or more definitive Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount and, if applicable, having
endorsed thereon notations of Subsidiary Guarantees executed by the Subsidiary Guarantors. Until so exchanged, the temporary Securities of any series shall in all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series and tenor. 
 SECTION 305 Registration, Registration of Transfer and Exchange.

 The Company shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such
office and in any other office or agency of the Company in a Place of Payment being herein sometimes collectively 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 “Security Registrar” for the purpose of registering Securities and transfers of Securities as herein provided.

 Upon surrender for registration of transfer of any Security of a series at the office or agency of the Company in a Place of
Payment for that series, the Company shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon and the Trustee shall authenticate and deliver, in the name of the designated
transferee or transferees, one or more new Securities of the same series, of any authorized denominations and of like tenor and aggregate principal amount. 
 At the option of the Holder, Securities of any series may be exchanged for other Securities of the same series, of any authorized denominations and of like tenor and 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 shall execute, if applicable the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees
endorsed thereon and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive. 
 All Securities issued upon any registration of transfer or exchange of Securities shall be the valid obligations of the Company, 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 304, 906, 1107 or otherwise not involving any transfer. 
 If the Securities of
any series (or of any series and specified tenor) are to be redeemed in part, the Company shall not be required (A) to issue, register the transfer of or exchange any Securities of that series (or of that series and specified tenor, as the case
may be) during a period beginning at the opening of business 15 days before the day of the mailing of a notice of redemption of any such Securities selected for redemption under Section 1103 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. 

  
 19 

 The provisions of clauses (1), (2), (3) and (4) below shall apply only to Global
Securities: 
 (1) Each Global Security authenticated under this Indenture shall be registered in the name of the Depositary
designated for such Global Security or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Security shall constitute a single Security for all purposes of this Indenture. 

(2) Notwithstanding any other provision in this Indenture, no Global Security may be exchanged in whole or in part for Securities
registered, and no transfer of a Global Security in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Security or a nominee thereof unless (A) such Depositary (i) has notified the
Company that it is unwilling or unable to continue as Depositary for such Global Security or (ii) has ceased to be a clearing agency registered under the Exchange Act, and in either case the Company fails to appoint a successor Depositary
within 90 days, (B) there shall have occurred and be continuing an Event of Default with respect to such Global Security and the Depositary shall have notified the Trustee of its decision to exchange such Global Security for Securities in
certificated form, (C) subject to the rules of the Depositary, the Company shall have elected to terminate the book-entry system through the Depositary or (D) there shall exist such circumstances, if any, in addition to or in lieu of the
foregoing as have been specified for this purpose as contemplated by Section 301. 
 (3) Subject to clause (2) above,
any exchange of a Global Security for other Securities may be made in whole or in part, and all Securities issued in exchange for a Global Security or any portion thereof shall be registered in such names as the Depositary for such Global Security
shall direct. 
 (4) Every Security authenticated and delivered upon registration of transfer of, or in exchange for or in lieu
of, a Global Security or any portion thereof, whether pursuant to this Section, Section 304, 306, 906 or 1107 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Security, unless such Security is registered
in the name of a Person other than the Depositary for such Global Security or a nominee thereof. 
 SECTION 306 Mutilated,
Destroyed, Lost and Stolen Securities. 
 If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, and, if applicable, the Subsidiary
Guarantors shall execute the notation of Subsidiary Guarantee endorsed thereon. 
 If there shall be delivered to the Company
and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Security and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless from any loss
that any of them may suffer if a Security is replaced, then, in the absence of notice to the Company or the Trustee that such Security has been acquired by a protected purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and of like tenor and principal amount and bearing a number not contemporaneously outstanding, and, if applicable, the Subsidiary Guarantors shall
execute the notation of Subsidiary Guarantee endorsed thereon. In case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable or is to be converted, the Company in its discretion may, instead of
issuing a new Security, pay or authorize the conversion of such Security (without surrender thereof save in the case of a mutilated 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, whether or not the destroyed, lost or stolen Security shall be at any time enforceable
by anyone, and shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of 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, payment or conversion of mutilated, destroyed, lost or
stolen Securities. 

  
 20 

 SECTION 307 Payment of Interest; Interest Rights Preserved. 

Except as otherwise provided as contemplated by Section 301 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 (1) or (2) below: 
 (1) 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 given to each Holder
of Securities of such series in the manner set forth in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so
mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date and shall no longer be payable
pursuant to the following clause (2). 
 (2) The 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 308 Persons Deemed Owners. 
 Prior to due presentment of a
Security for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee and any agent of the Company, the Subsidiary Guarantors, or the Trustee 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 307) any interest on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company,
any Subsidiary Guarantor, the Trustee nor any agent of the Company, any Subsidiary Guarantor, or the Trustee shall be affected by notice to the contrary. 
 SECTION 309 Cancellation. 
 All Securities surrendered for payment,
redemption, purchase, registration of transfer or exchange or for credit against any sinking fund payment shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The 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 cancelled by the Trustee. No Securities shall be authenticated in lieu of or

accordance with its standard procedures, unless as directed by a Company Order. 
 SECTION 310 Computation of
Interest. 
 Except as otherwise specified as contemplated by Section 301 for Securities of any series, interest on
the Securities of each series shall be computed on the basis of a 360-day year of twelve 30-day months.

reason of a release of such Subsidiary Guarantor from its Subsidiary Guarantee in accordance with the terms of this Indenture); or 
 (11) any other Event of Default provided with respect to Securities of that series. 
 SECTION 502 Acceleration of Maturity; Rescission and Annulment. 
 If
an Event of Default (other than an Event of Default with respect to the Company specified in Section 501(8) or 501(9)) with respect to Securities of any series at the time Outstanding occurs and is continuing, then in every such case the
Trustee or the Holders of not less than 25% in principal amount of the Outstanding Securities of that series may declare the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount
Securities, such portion of the principal amount of such Securities as may be specified by the terms thereof) 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), together with any accrued and unpaid interest thereon, shall become immediately due and payable. If an Event of Default with respect to the Company specified in Section 501(8) or 501
(9) with respect to Securities of any series at the time Outstanding occurs, the principal amount of all the Securities of that series (or, if any Securities of that series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified by the terms thereof), together with any accrued and unpaid interest thereon, shall automatically, and without any declaration or other action on the part of the Trustee or any Holder, become immediately
due and payable. 
 At any time after such a declaration of acceleration with respect to Securities of any series has been made
and before a judgment or decree for payment of the money due has been obtained by the Trustee as hereinafter in this Article provided, the Holders of a majority in principal amount of the Outstanding Securities of that series, by written notice to
the Company and the Trustee, may rescind and annul such declaration and its consequences if 
 (1) the Company or, if
applicable, any Subsidiary Guarantor has paid or deposited with the Trustee a sum sufficient to pay 
 (A) all
overdue interest on all Securities of that series, 
 (B) the principal of (and premium, if any, on) any
Securities of that series which have become due otherwise than by such declaration of acceleration and any interest thereon at the rate or rates prescribed therefor in such Securities, 

  
 24 

 (C) to the extent that payment of such interest is lawful, interest upon
overdue interest at the rate or rates prescribed therefor in such Securities, and 
 (D) all sums paid or
advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel; and 
 (2) all Events of Default with respect to Securities of that series, other than the non-payment of the principal of Securities of that series which has become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 513. 
 No such rescission shall affect any subsequent
default or impair any right consequent thereon. 
 SECTION 503 Collection of Indebtedness and Suits for Enforcement by
Trustee. 
 The Company covenants that if 
 (1) default is made in the payment of any interest on any Security when such interest becomes due and payable and such default continues for a period of 30 days, or 

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

the 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 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 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 504 Trustee May File Proofs of Claim. 
 In case of any
judicial proceeding relative to the Company, any Subsidiary Guarantor or any other obligor upon the Securities, or the property or creditors of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be
entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In particular, the
Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official
in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due it
for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 607. 
 No provision of this Indenture shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or
composition affecting the Securities or any Subsidiary 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 505 Trustee May Enforce Claims Without Possession of Securities. 
 All rights of action and claims under this Indenture or the Securities or any Subsidiary Guarantee 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 

  
 25 

 
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 506 Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article 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 607; 

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 or to such other Person as a court of competent jurisdiction shall direct.

 SECTION 507 Limitation on Suits. 
 No Holder of any Security of any series shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any
other remedy hereunder, unless 
 (1) such Holder has previously given written notice to the Trustee of a continuing Event of
Default with respect to the Securities of that series; 
 (2) the Holders of not less than 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; 

(3) such Holder or Holders have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities to be
incurred in compliance with such request; 
 (4) the Trustee for 60 days after its receipt of such notice, request and
offer of security or indemnity has failed to institute any such proceeding; and 
 (5) no direction inconsistent with such
written request has been given to the Trustee during such 60-day period by the Holders of a majority in principal amount of the Outstanding Securities of that series; 
 it being understood and intended that no one or more of such Holders shall have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture to affect, disturb or
prejudice the rights of any other of such Holders, or to obtain or to seek to obtain priority or preference over any other of such Holders or to enforce any right under this Indenture, except in the manner herein provided and for the equal and
ratable benefit of all of such Holders. 
 SECTION 508 Unconditional Right of Holders to Receive Principal, Premium and
Interest. 
 Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right,
which is absolute and unconditional, to receive payment of the principal of and any premium and (subject to Section 307) interest on such Security on the respective Stated Maturities expressed in such Security (or, in the case of redemption or
offer by the Company to purchase the Securities pursuant to the terms of this Indenture, on the Redemption Date or purchase date, as applicable) and, if applicable, to convert such Security in accordance with its terms, and to institute suit for the
enforcement of any such right, and such rights shall not be impaired without the consent of such Holder. 

  
 26 

 SECTION 509 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 Subsidiary 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. 

SECTION 510 Rights and Remedies Cumulative. 
 Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities in the last paragraph of Section 306, no right or remedy herein conferred
upon or reserved to the Trustee or to 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 511 Delay or Omission Not Waiver. 

No delay or omission of the Trustee or of any Holder of any Securities to exercise any right or remedy accruing upon any Event of Default
shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as
often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 SECTION 512 Control by
Holders. 
 The Holders of a majority in principal amount of the Outstanding Securities of any series shall have the
right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series, provided that 

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

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction. 

SECTION 513 Waiver of Past Defaults. 
 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 a default 
 (1) in the payment of the principal of or any premium or
interest on any Security of such series (including any Security which is required to have been purchased by the Company pursuant to an offer to purchase by the Company made pursuant to the terms of this Indenture), or 

(2) 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. 
 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 514 Undertaking for Costs. 
 In any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, a court may require any party
litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the Trust Indenture Act; provided, however, that neither this Section nor
the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company or any Subsidiary Guarantor. 

  
 27 

 SECTION 515 Waiver of Usury, Stay or Extension Laws. 

Each of the Company and the Subsidiary 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 usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this
Indenture; and each of the Company and the Subsidiary 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. 
 ARTICLE SIX

SECTION 601 Certain Duties and Responsibilities. 
 The duties and responsibilities of the Trustee shall be as expressly set forth in this Indenture and as provided by the Trust Indenture Act. Notwithstanding the foregoing, no provision of this Indenture
shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for

request or direction of any of the Holders pursuant to this Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which might be incurred by it in compliance
with such request or direction;

stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make
such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine the books, records and premises of the Company,

representations as to the validity or sufficiency of this Indenture or of the Securities or the Subsidiary Guarantees. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or
the proceeds thereof. 
 SECTION 605 May Hold Securities. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company or any Subsidiary
Guarantor, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 608 and 613, may otherwise deal with the Company and any Subsidiary Guarantor with the same rights it would have if it
were not Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent. 
 SECTION 606 Money Held in
Trust. 
 Money held by the Trustee in trust hereunder need not be segregated from other funds except to the extent
required by law. The Trustee shall be under no liability for interest on any money received by it hereunder except as otherwise agreed with the Company or any Subsidiary Guarantor, as the case may be.

 (3) to indemnify the Trustee for, and to hold it harmless against,
any loss, liability or expense incurred without negligence or bad faith on its part, arising out of or in connection with the acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself against
any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. 
 SECTION 608
Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the
Trust Indenture Act, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the Trust Indenture Act and this Indenture. To the extent permitted by such Act, the

 SECTION 609 Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to the Securities of each series, which may be Trustee
hereunder for Securities of one or more other series. Each Trustee shall be a Person that is eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000. If any such Person publishes
reports of condition at least annually, pursuant to law or to the requirements of its supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus
of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee with respect to the Securities of any series shall cease to be eligible in accordance
with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article. 
 SECTION 610 Resignation and Removal; Appointment of Successor. 
 No
resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of
Section 611. 
 The Trustee may resign at any time with respect to the Securities of one or more series by giving written
notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 611 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee
may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 
 The Trustee may be removed at any time with respect to the Securities of any series by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series, delivered to the
Trustee and to the Company. 
 If at any time: 
 (1) the Trustee shall fail to comply with Section 608 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

 (2) the Trustee shall cease to be eligible under Section 609 and shall fail to resign after written request therefor by
the Company or by any such Holder, or 
 (3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or
insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation, then, in any
such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities, or (B) subject to Section 514, any Holder who has been a bona fide Holder of a Security for at least six months may, on behalf of
himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees. 

If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any
cause, with respect to the Securities of one or more series, the 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 611. 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 611, 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 

  
 30 

 
any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 611, any Holder who has been a bona fide Holder of a Security
of such series for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series. 

The 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 106. 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 611 Acceptance of Appointment by
Successor. 
 In case of the appointment hereunder of a successor Trustee with respect to all Securities, every such
successor Trustee so appointed shall execute, acknowledge and deliver to the Company, the Subsidiary Guarantors 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 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. 
 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 Subsidiary Guarantors, 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 (1) 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, (2) 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 (3) 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 or any successor Trustee, such retiring Trustee 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 that or those series to which the appointment of such successor Trustee relates. 

Upon request of any such successor Trustee, the Company and the Subsidiary 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 the first or second preceding paragraph, as the case may be. 

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 SECTION 612 Merger, Conversion, Consolidation or Succession to Business.

 Any Person into which the Trustee may be merged or converted or with which it may be consolidated, or any Person resulting
from any merger, conversion or consolidation to which the Trustee shall be a party, or any Person succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such
Person shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. As soon as practicable, the successor Trustee shall mail a notice of its
succession to the Company and the Holders of the Securities then 

  
 31 

 
Outstanding. 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 613 Preferential Collection of Claims Against Company and Subsidiary Guarantors. 
 If and when the Trustee shall be or become a creditor of the Company, any Subsidiary Guarantor or any other obligor upon the Securities, the Trustee shall be subject to the provisions of the Trust
Indenture Act regarding the collection of claims against the Company, such Subsidiary Guarantor or any such other obligor. 

SECTION 614 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 original issue and upon exchange, registration of transfer, conversion or partial redemption thereof or pursuant to Section 306, 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 Person 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 Person into which an Authenticating Agent may be merged or converted or with which it may be consolidated,
or any Person resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any Person succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be
an Authenticating Agent, provided such Person 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. 

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. 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. 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 shall give notice of such appointment in the manner provided in
Section 106 to all Holders of Securities of the series with respect to which such Authenticating Agent will serve. 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. 

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and
the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 607. 

  
 32 

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

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

any premium and interest on the Securities of that series in accordance with the terms of the Securities and this Indenture. Principal, premium, if any, and interest shall be considered paid on the date due if the Paying Agent, if other than the

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 11:00 A.M., New York City
time, on each due date of the principal of or any premium or interest on any Securities of that series, deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such
Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to act. 
 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 (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the continuance of any default by the Company, the Subsidiary Guarantors, if applicable, or any other obligor upon the
Securities of that series in the making of any payment in respect of the Securities of that series, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for payment in respect of the
Securities of that series. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of this
Indenture or for any other purpose, pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same 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. 

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
any premium or interest on any Security of any series and remaining unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the 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
a newspaper published in the English language, customarily published on each Business Day and of general circulation in The City of New York, New York, 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 1004 Statement by Officers as to Default. 
 (a) The Company
and the Subsidiary Guarantors will deliver to the Trustee, within 90 days after the end of each fiscal year of the Company ending after the date hereof, an Officers’ Certificate, stating whether or not to the best knowledge of the signers
thereof the Company or any Subsidiary Guarantor, as the case may be, is in default in the performance and observance of any of the terms, provisions and conditions of this Indenture (without regard to any period of grace or requirement of notice
provided hereunder) and, if the Company or any Subsidiary Guarantor shall be in default, specifying all such defaults and the nature and status thereof of which they may have knowledge. 

(b) The Company shall, so long as any series of Securities is Outstanding, deliver to the Trustee, as soon as possible and in any event
within five days after the Company becomes aware of the occurrence of an Event of Default or an event which, with notice or the lapse of time or both, would constitute an Event of Default, an Officers’ Certificate setting forth the details of
such Event of Default or default, and the action which the Company proposes to take with respect thereto. 

  
 38 

 SECTION 1005 Existence. 

Subject to Article Eight, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect
the existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer desirable
in the conduct of the business of the Company and that the loss thereof is not disadvantageous in any material respect to the Holders. 
 SECTION 1006 Maintenance of Properties. 
 The Company will cause all
properties used or useful in the conduct of its business or the business of any Subsidiary to be maintained and kept in good condition, repair and working order (reasonable wear and tear excepted) and supplied with all necessary equipment and will
cause to be made all necessary repairs, renewals, replacements, betterments and improvements thereof, all as in the judgment of the Company may be necessary so that the business carried on in connection therewith may be properly and advantageously
conducted at all times; provided, however, that nothing in this Section shall prevent the Company from discontinuing the operation or maintenance of any of such properties if such discontinuance is, in the judgment of the Company, desirable in the
conduct of its business or the business of any Subsidiary and not disadvantageous in any material respect to the Holders. 

SECTION 1007 Payment of Taxes and Other Claims. 
 The Company will pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (1) all taxes, assessments and governmental charges levied or imposed upon the Company or
any Subsidiary or upon the income, profits or property of the Company or any Subsidiary, and (2) all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon the property of the Company or any
Subsidiary; provided, however, that the Company shall not be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith by
appropriate proceedings. 
 SECTION 1008 Maintenance of Insurance. 

The Company shall, and shall cause its Subsidiaries to, keep at all times all of their properties which are of an insurable nature
insured against loss or damage with insurers believed by the Company to be responsible to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties in accordance with good
business practice. 
 SECTION 1009 Waiver of Certain Covenants. 

Except as otherwise specified as contemplated by Section 301 for Securities of such series, the Company and the Subsidiary
Guarantors may, with respect to the Securities of any series, omit in any particular instance to comply with any term, provision or condition set forth in any of Sections 1005 through 1008 or in any covenant provided pursuant to
Section 301(21), 901(2) or 901(7) for the benefit of the Holders of such series if before the time for such compliance the Holders of at least a majority in principal amount of the Outstanding Securities of such series shall, by Act of such
Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition, but no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect. 

ARTICLE ELEVEN 
 REDEMPTION OF SECURITIES 
 SECTION 1101 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 301 for such Securities) in accordance with this Article. 

  
 39 

 SECTION 1102 Election to Redeem; Notice to Trustee. 

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or in another manner specified as
contemplated by Section 301 for such Securities. In case of any redemption at the election of the Company of less than all the Securities of any series (including any such redemption affecting only a single Security), the Company shall, at
least five Business Days prior to giving notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of the principal amount of Securities of such series to be redeemed and,
if applicable, of the tenor of the Securities to be redeemed. In the case of any redemption of Securities prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture, the
Company shall furnish the Trustee with an Officers’ Certificate evidencing compliance with such restriction. 
 SECTION
1103 Selection by Trustee of Securities to Be Redeemed. 
 If less than all the Securities of any series are to be
redeemed (unless all the Securities of such series and of a specified tenor are to be redeemed or unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding
Securities of such series not previously called for redemption, (i) in compliance with the requirements of the principal national securities exchange on which such Securities are listed, if such Securities are listed on any national securities
exchange, and (ii) if such Securities are not so listed, on a pro rata basis, by lot or by such other method as the Trustee shall deem fair and appropriate and which may provide for the selection for redemption of a portion of the principal
amount of any Security of such series, provided that the unredeemed portion of the principal amount of any Security shall be in an authorized denomination (which shall not be less than the minimum authorized denomination) for such Security. If less
than all the Securities of such series and of a specified tenor are to be redeemed (unless such redemption affects only a single Security), the particular Securities to be redeemed shall be selected by the Trustee, from the Outstanding Securities of
such series and specified tenor not previously called for redemption in accordance with the preceding sentence. 
 The Trustee
shall promptly notify the Company in writing of the Securities selected for redemption as aforesaid and, in case of any Securities selected for partial redemption as aforesaid, the principal amount thereof to be redeemed. 

The provisions of the two preceding paragraphs shall not apply with respect to any redemption affecting only a single Security, whether
such Security is to be redeemed in whole or in part. In the case of any such redemption in part, the unredeemed portion of the principal amount of the Security shall be in an authorized denomination (which shall not be less than the minimum
authorized denomination) for such Security. 
 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. If any Security
selected for partial redemption is surrendered for conversion after such selection, the converted portion of such Security shall be deemed (so far as may be) to be the portion selected for redemption. Upon any redemption of less than all the
Securities of a series, for purposes of selection for redemption the Company and the Trustee may treat as Outstanding Securities surrendered for conversion during the period of 15 days next preceding the mailing of a notice of redemption, and
need not treat as Outstanding any Security authenticated and delivered during such period in exchange for the unconverted portion of any Security converted in part during such period. 

SECTION 1104 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; provided, however, notice of redemption may be given more than 60 days prior to the Redemption Date if the notice is issued in connection with a satisfaction and discharge pursuant to
Article Four. 
 All notices of redemption shall state: 

(1) the Redemption Date, 
 (2) the Redemption Price, if then determinable and otherwise the method of its determination, 

  
 40 

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

(5) the place or places where each such Security is to be surrendered for payment of the Redemption Price, 

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

(7) if applicable, the conversion price then in effect and the date on which the right to convert such Securities will expire.

 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 and shall be irrevocable. If any Security called for redemption is converted pursuant hereto, any money deposited with the Trustee or any Paying Agent or so
segregated and held in trust for the redemption of such Security shall be paid to the Company upon delivery of a Company Request to the Trustee or such Paying Agent, or, if then held by the Company, shall be discharged from such trust. 

SECTION 1105 Deposit of Redemption Price. 
 Prior to 11:00 A.M., New York City time, on 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 1003) 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 1106 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 as contemplated by
Section 301, installments of interest whose Stated Maturity is on or prior to the Redemption Date will 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 307. 
 If any Security called for redemption
shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Security. 

  
 41 

 SECTION 1107 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, if
applicable, the Subsidiary Guarantors shall execute the notations of Subsidiary Guarantees endorsed thereon, and the Trustee shall authenticate and deliver to the Holder of such Security without service charge, a new Security or Securities of the
same series and of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered. 

ARTICLE TWELVE 
 [INTENTIONALLY OMITTED] 
 ARTICLE THIRTEEN 

SUBSIDIARY GUARANTEES 
 SECTION 1301 Applicability of Article. 
 Unless the Company elects
to issue any series of Securities without the benefit of the Subsidiary Guarantees, which election shall be evidenced in or pursuant to the Board Resolution or supplemental indenture establishing such series of Securities pursuant to
Section 301, the provisions of this Article shall be applicable to each series of Securities except as otherwise specified in or pursuant to the Board Resolution or supplemental indenture establishing such series pursuant to Section 301.

 SECTION 1302 Subsidiary Guarantees. 
 Subject to Section 1301, each Subsidiary Guarantor hereby, jointly and severally, fully and unconditionally guarantees to each Holder of a Security authenticated and delivered by the Trustee, the due
and punctual payment of the principal of (and premium, if any) and interest on such Security when and as the same shall become due and payable, whether at the Stated Maturity, by acceleration, call for redemption, offer to purchase or otherwise, in
accordance with the terms of such Security and of this Indenture, and each Subsidiary Guarantor similarly guarantees to the Trustee the payment of all amounts owing to the Trustee in accordance with the terms of this Indenture. In case of the
failure of the Company punctually to make any such payment, each Subsidiary Guarantor hereby, jointly and severally, agrees to cause such payment to be made punctually when and as the same shall become due and payable, whether at the Stated Maturity
or by acceleration, call for redemption, offer to purchase or otherwise, and as if such payment were made by the Company. 

Each of the Subsidiary Guarantors hereby jointly and severally agrees that its obligations hereunder shall be absolute, unconditional,
irrespective of, and shall be unaffected by, the validity, regularity or enforceability of such Security or this Indenture, the absence of any action to enforce the same or any release, amendment, waiver or indulgence granted to the Company or any
other guarantor or any consent to departure from any requirement of any other guarantee of all or any of the Securities of such series or any other circumstances which might otherwise constitute a legal or equitable discharge or defense of a surety
or guarantor; provided, however, that, notwithstanding the foregoing, no such release, amendment, waiver or indulgence shall, without the consent of such Subsidiary Guarantor, increase the principal amount of such Security, or increase the interest
rate thereon, or alter the Stated Maturity thereof. Each of the Subsidiary Guarantors hereby waives the benefits of diligence, presentment, demand for payment, any requirement that the Trustee or any of the Holders protect, secure, perfect or insure
any security interest in or other lien on any property subject thereto or exhaust any right or take any action against the Company or any other Person or any collateral, 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 or notice with respect to such Security or the indebtedness evidenced thereby and all demands whatsoever, and covenants that this Subsidiary Guarantee will not be
discharged in respect of such Security except by complete performance of the obligations contained in such Security and in such Subsidiary Guarantee. Each Subsidiary Guarantor agrees that if, after the occurrence and during the continuance of an
Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Securities of a series, to collect interest on the Securities of a series, or to enforce or
exercise any other right or remedy with respect to the Securities of a series, such Subsidiary Guarantor agrees to pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had
such rights and remedies been permitted to be exercised by the Trustee or any of the Holders. 

  
 42 

 Each Subsidiary Guarantor shall be subrogated to all rights of the Holders of the Securities
upon which its Subsidiary Guarantee is endorsed against the Company in respect of any amounts paid by such Subsidiary Guarantor on account of such Security pursuant to the provisions of its Subsidiary Guarantee or this Indenture; provided, however,
that no Subsidiary Guarantor shall be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation until the principal of (and premium, if any) and interest on all Securities of the relevant series issued
hereunder shall have been paid in full. 
 Each Subsidiary Guarantor that makes or is required to make any payment in respect of
its Subsidiary Guarantee shall be entitled to seek contribution from the other Subsidiary Guarantors to the extent permitted by applicable law; provided, however, that no Subsidiary Guarantor shall be entitled to enforce or receive any payments
arising out of, or based upon, such right of contribution until the principal of (and premium, if any) and interest on all Securities of the relevant series issued hereunder shall have been paid in full. 

Each Subsidiary Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against
the Company for liquidation or reorganization, should the Company become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any part of the Company’s assets, and shall, to the
fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Securities of a series, is, pursuant to applicable law, rescinded or reduced in amount, or must otherwise
be restored or returned by any Holder of the Securities, whether as a “voidable preference,” “fraudulent transfer,” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any
part thereof, is rescinded, reduced, restored or returned, the Securities shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned. 

SECTION 1303 Execution and Delivery of Notations of Subsidiary Guarantees. 

To further evidence the Subsidiary Guarantee set forth in Section 1302, each of the Subsidiary Guarantors hereby agrees that a
notation relating to such Subsidiary Guarantee, substantially in the form set forth in Section 204, shall be endorsed on each Security entitled to the benefits of the Subsidiary Guarantee authenticated and delivered by the Trustee and executed
by either manual or facsimile signature of an officer of such Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, an officer of the general partner of each Subsidiary Guarantor. Each of the Subsidiary
Guarantors hereby agrees that the Subsidiary Guarantee set forth in Section 1302 shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation relating to the Subsidiary Guarantee. If any officer of
the Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, any officer of the general partner of the Subsidiary Guarantor, whose signature is on this Indenture or a Security no longer holds that office at the
time the Trustee authenticates such Security or at any time thereafter, the Subsidiary Guarantee of such Security shall be valid nevertheless. The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute
due delivery of the Subsidiary Guarantee set forth in this Indenture on behalf of the Subsidiary Guarantors. 
 SECTION 1304
Release of Subsidiary Guarantors. 
 Unless otherwise specified pursuant to Section 301 with respect to a
series of Securities, each Subsidiary Guarantee will remain in effect with respect to the respective Subsidiary Guarantor until the entire principal of, premium, if any, and interest on the Securities to which such Subsidiary Guarantee relates shall
have been paid in full or otherwise satisfied and discharged in accordance with the provisions of such Securities and this Indenture and all amounts owing to the Trustee hereunder have been paid; provided, however, that if (i) such Subsidiary
Guarantor ceases to be a Subsidiary in compliance with the applicable provisions of this Indenture, (ii) either Defeasance or Covenant Defeasance occurs with respect to such Securities pursuant to Article Fifteen or (iii) all or
substantially all of the assets of such Subsidiary Guarantor or all of the Capital Stock of such Subsidiary Guarantor is sold (including by sale, merger, consolidation or otherwise) by the Company or any Subsidiary in a transaction complying with
the requirements of this Indenture, then, in each case of (i), (ii) or (iii), upon delivery by the Company of an Officers’ Certificate and an Opinion of Counsel stating that all conditions precedent herein provided for relating to the
release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee and this Article Thirteen have been complied with, such Subsidiary Guarantor shall be released and discharged of its obligations under its Subsidiary

  
 43 

 
Guarantee and under this Article Thirteen without any action on the part of the Trustee or any Holder, and the Trustee shall execute any documents reasonably required in order to acknowledge
the release of such Subsidiary Guarantor from its obligations under its Subsidiary Guarantee endorsed on the Securities of such series and under this Article Thirteen. 
 SECTION 1305 Additional Subsidiary Guarantors. 
 Unless otherwise
specified pursuant to Section 301 with respect to a series of Securities, the Company will cause any domestic Wholly Owned Subsidiary of the Company that becomes a Subsidiary after the date the Securities of a series are first issued hereunder
to become a Subsidiary Guarantor as soon as practicable after such Subsidiary becomes a Subsidiary. The Company shall cause any such Wholly Owned Subsidiary to become a Subsidiary Guarantor with respect to the Securities by executing and delivering
to the Trustee (a) a supplemental indenture, in form and substance satisfactory to the Trustee, which subjects such Person to the provisions (including the representations and warranties) of this Indenture as a Subsidiary Guarantor and
(b) an Opinion of Counsel to the effect that such supplemental indenture has been duly authorized and executed by such Person and such supplemental indenture and such Person’s obligations under its Subsidiary Guarantee and this Indenture
constitute the legal, valid, binding and enforceable obligations of such Person (subject to such customary exceptions concerning creditors’ rights and equitable principles as may be acceptable to the Trustee in its discretion). 

SECTION 1306 Limitation on Liability. 
 Any term or provision of this Indenture to the contrary notwithstanding, the maximum amount of the Subsidiary Guarantee of any Subsidiary Guarantor shall not exceed the maximum amount that can be hereby
guaranteed by such Subsidiary Guarantor without rendering such Subsidiary Guarantee voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally. 

ARTICLE FOURTEEN 
 [INTENTIONALLY OMITTED] 
 ARTICLE FIFTEEN 

DEFEASANCE AND COVENANT DEFEASANCE 
 SECTION 1501 Company’s Option to Effect Defeasance or Covenant Defeasance. 
 The Company may elect, at its option at any time, to have Section 1502 or Section 1503 applied to any Securities or any series of Securities, as the case may be, designated pursuant to
Section 301 as being defeasible pursuant to such Section 1502 or 1503, in accordance with any applicable requirements provided pursuant to Section 301 and upon compliance with the conditions set forth below in this Article. Any such
election shall be evidenced in or pursuant to a Board Resolution or in another manner specified as contemplated by Section 301 for such Securities. 
 SECTION 1502 Defeasance and Discharge. 
 Upon the Company’s
exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, the Company shall be deemed to have been discharged from its obligations, and each Subsidiary Guarantor shall be deemed
to have been discharged from its obligations with respect to its Subsidiary Guarantee of such Securities, as provided in this Section on and after the date the conditions set forth in Section 1504 are satisfied (herein called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Securities and to have satisfied all its other obligations under such
Securities and this Indenture insofar as such Securities are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of such Securities to receive, solely from the trust fund described in Section 1504 and as more fully set forth in such Section, payments in respect of the principal of and any premium and
interest on such Securities when payments are due, or, if applicable, to convert such Securities in accordance with their terms, (2) the Company’s and each Subsidiary Guarantor’s obligations with respect to such Securities under
Sections 304, 305, 306, 1002 and 1003, and, if applicable, their obligations with respect to the conversion of such Securities, (3) the rights, powers, trusts, 

  
 44 

 
duties and immunities of the Trustee hereunder and (4) this Article. Subject to compliance with this Article, the Company may exercise its option (if any) to have this Section applied to any
Securities notwithstanding the prior exercise of its option (if any) to have Section 1503 applied to such Securities. 

SECTION 1503 Covenant Defeasance. 
 Upon the Company’s exercise of its option (if any) to have this Section applied to any Securities or any series of Securities, as the case may be, (1) the Company shall be released from its
obligations under Section 801(3), Sections 1005 through 1008, inclusive, and any covenants provided pursuant to Section 301(21), 901(2) or 901(7) for the benefit of the Holders of such Securities, and (2) the occurrence of any
event specified in Sections 501(5) (with respect to any of Section 801(3), Sections 1006 through 1008, inclusive, and any such covenants provided pursuant to Section 301(21), 901(2) or 901(7)), 501(6), 501(7)), 501(10) and
501(11) shall be deemed not to be or result in an Event of Default and (3) the provisions of Article Thirteen shall cease to be effective, in each case with respect to such Securities and Subsidiary Guarantees as provided in this Section
on and after the date the conditions set forth in Section 1504 are satisfied (herein called “Covenant Defeasance”). For this purpose, such Covenant Defeasance means that, with respect to such Securities, the Company and the
Subsidiary Guarantors, as applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section (to the extent so specified in the case of Section 501(5)) or
Article Thirteen, whether directly or indirectly by reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the
remainder of this Indenture and such Securities shall be unaffected thereby. 
 SECTION 1504 Conditions to Defeasance or
Covenant Defeasance. 
 The following shall be the conditions to the application of Section 1502 or
Section 1503 to any Securities or any series of Securities, as the case may be: 
 (1) The Company shall irrevocably have
deposited or caused to be deposited with the Trustee (or another trustee which satisfies the requirements contemplated by Section 609 and agrees to comply with the provisions of this Article applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for, and dedicated solely to, the benefits of the Holders of such Securities, (A) money in an amount, or (B) U.S. Government Obligations which through the scheduled
payment of principal and interest in respect thereof in accordance with their terms will provide, not later than one day before the due date of any payment, money in an amount, or (C) a combination thereof, in each case sufficient, in the
opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or any such other qualifying trustee)
to pay and discharge, the principal of and any premium and interest on such Securities on the respective Stated Maturities, in accordance with the terms of this Indenture and such Securities. As used herein, “U.S. Government
Obligation” means (x) any security which is (i) a direct obligation of the United States of America for the payment of which the full faith and credit of the United States of America is pledged or (ii) an obligation of a
Person controlled or supervised by and acting as an agency or instrumentality of the United States of America the payment of which is unconditionally guaranteed as a full faith and credit obligation by the United States of America, which, in either
case (i) or (ii), is not callable or redeemable at the option of the issuer thereof, and (y) any depositary receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act) as custodian with respect to any U.S.
Government Obligation which is specified in clause (x) above and held by such bank for the account of the holder of such depositary receipt, or with respect to any specific payment of principal of or interest on any U.S. Government Obligation
which is so specified and held, provided that (except as required by law) such custodian is not authorized to make any deduction from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of
the U.S. Government Obligation or the specific payment of principal or interest evidenced by such depositary receipt. 
 (2) In
the event of an election to have Section 1502 apply to any Securities or any series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel stating that (A) the Company has received from, or
there has been published by, the Internal Revenue Service a ruling or (B) since the date of this instrument, there has been a change in the applicable Federal income tax law, in either case (A) or (B) to the effect that, and based
thereon such opinion shall confirm that, the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the deposit, Defeasance and discharge to be effected with respect to such Securities and will be
subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Defeasance were not to occur. 

  
 45 

 (3) In the event of an election to have Section 1503 apply to any Securities or any
series of Securities, as the case may be, the Company shall have delivered to the Trustee an Opinion of Counsel to the effect that the Holders of such Securities will not recognize gain or loss for Federal income tax purposes as a result of the
deposit and Covenant Defeasance to be effected with respect to such Securities and will be subject to Federal income tax on the same amount, in the same manner and at the same times as would be the case if such deposit and Covenant Defeasance were
not to occur. 
 (4) The Company shall have delivered to the Trustee an Officers’ Certificate to the effect that neither
such Securities nor any other Securities of the same series, if then listed on any securities exchange, will be delisted as a result of such deposit. 
 (5) No event which is, or after notice or lapse of time or both would become, an Event of Default with respect to such Securities shall have occurred and be continuing at the time of such deposit or, with
regard to any such event specified in Sections 501(7) and (8), at any time on or prior to the 121st day after the date of such deposit (it being understood that this condition shall not be deemed satisfied until after such 121st day).

 (6) Such Defeasance or Covenant Defeasance shall not cause the Trustee to have a conflicting interest within the meaning of
the Trust Indenture Act (assuming all Securities are in default within the meaning of such Act). 
 (7) Such Defeasance or
Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any other agreement or instrument to which the Company or any Subsidiary is a party or by which it is bound. 

(8) The Company shall have delivered to the Trustee an Opinion of Counsel to the effect that such deposit shall not cause either the
Trustee or the trust so created to be subject to the Investment Company Act of 1940. 
 (9) The Company shall have delivered to
the Trustee an Officers’ Certificate and an Opinion of Counsel, each stating that all conditions precedent with respect to such Defeasance or Covenant Defeasance have been complied with. 

SECTION 1505 Deposited Money and U.S. Government Obligations to Be Held in Trust; Miscellaneous Provisions. 

Subject to the provisions of the last paragraph of Section 1003, all money and U.S. Government Obligations (including the proceeds
thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1506, the Trustee and any such other trustee are referred to collectively as the “Trustee”) pursuant to
Section 1504 in respect of any Securities shall 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 such Paying Agent (including
the Company acting as its own 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 and any premium and interest, but money so held in trust need not be
segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the Trustee against any
tax, fee or other charge imposed on or assessed against the U.S. Government Obligations deposited pursuant to Section 1504 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 Outstanding Securities. 
 Anything in this Article to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company Request any money or U.S. Government Obligations held by it as provided in Section 1504 with respect to any Securities which, in the opinion of a nationally recognized
firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect the Defeasance or Covenant Defeasance, as the
case may be, with respect to such Securities. 

  
 46 

 SECTION 1506 Reinstatement. 

If the Trustee or the Paying Agent is unable to apply any money in accordance with this Article with respect to any Securities by reason
of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under this Indenture and such Securities from which the Company has been discharged or released
pursuant to Section 1502 or 1503 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Securities, until such time as the Trustee or Paying Agent is permitted to apply all money held in
trust pursuant to Section 1505 with respect to such Securities in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Security following such
reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Securities to receive such payment from the money so held in trust. 

ARTICLE SIXTEEN 
 SINKING FUNDS 
 SECTION 1601 Applicability of Article.

 The provisions of this Article shall be applicable to any sinking fund for the retirement of Securities of any series except
as otherwise specified as contemplated by Section 301 for such Securities. 
 The minimum amount of any sinking fund
payment provided for by the terms of any Securities 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 such Securities is herein referred to as an
“optional sinking fund payment.” If provided for by the terms of any Securities, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 1602. Each sinking fund payment shall be applied to the
redemption of Securities as provided for by the terms of such Securities. 
 SECTION 1602 Satisfaction of Sinking Fund
Payments with Securities. 
 The Company (1) may deliver Outstanding Securities of a series (other than any
previously called for redemption) and (2) may apply as a credit Securities of a series which have been (x) converted or (y) 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 any Securities of such series required to be made pursuant
to the terms of such Securities as and to the extent provided for by the terms of such Securities; provided, however, that the Securities to be so credited have not been previously so credited. The Securities to be so credited shall be received and
credited for such purpose by the Trustee at the Redemption Price, as specified in the Securities so to be redeemed, for redemption through operation of the sinking fund and the amount of such sinking fund payment shall be reduced accordingly.

 SECTION 1603 Redemption of Securities for Sinking Fund. 

Not less than 35 days prior to each sinking fund payment date for any Securities, the Company will deliver to the Trustee an
Officers’ Certificate specifying the amount of the next ensuing sinking fund payment for such Securities pursuant to the terms of such Securities, 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 pursuant to Section 1602 and will also deliver to the Trustee any Securities to be so delivered. Not less than 32 days prior to each such sinking fund payment date,
the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 1103 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the
manner provided in Section 1104. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 1106 and 1107. This instrument may be executed in any number of
counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument.

Base Indenture and this Supplemental Indenture, the “Indenture”). 
 RECITALS OF THE COMPANY AND THE
SUBSIDIARY GUARANTORS 
 The Company and the Subsidiary Guarantors have duly authorized, executed and delivered the Base
Indenture to provide for the issuance from time to time of the Company’s unsecured debentures, notes or other evidences of indebtedness (herein called the “Securities”), to be issued in one or more series, and the Guarantee by
each of the Subsidiary Guarantors of the Securities, as the Base Indenture provides. 
 Section 901(7) of the Base
Indenture provides, among other things, that the Company, the Subsidiary Guarantors and the Trustee may enter into indentures supplemental to the Base Indenture, without the consent of any Holders of Securities (as defined in the Base Indenture), to

 Pursuant to Sections
201 and 301 of the Base Indenture, the Company desires to execute this Supplemental Indenture to establish the form and terms, and to provide for the issuance, of a series of senior notes designated as 7.00% Senior Notes due 2021 in an aggregate
principal amount of $250,000,000 (the “Initial Notes”). 
 From time to time subsequent to the Issue Date, the
Company may, if permitted to do so pursuant to the terms of the Indenture, the Initial Notes and the terms of its other indebtedness existing on such future date, issue additional senior notes of the same series as the Initial Notes in accordance
with this Supplemental Indenture (the “Additional Notes” and, together with the Initial Notes, the “Notes”), pursuant to this Supplemental Indenture. 

The Company and the Subsidiary Guarantors are members of the same consolidated group of companies. The Subsidiary Guarantors will derive
direct and indirect economic benefit from the issuance of the Securities. Accordingly, each Subsidiary Guarantor has duly authorized the execution and delivery of this Supplemental Indenture to provide for its full, unconditional and joint and
several Guarantee of the Notes to the extent provided in or pursuant to the Indenture. 
 This Supplemental Indenture is subject
to the provisions of the Trust Indenture Act of 1939, as amended, that are required to be a part of this Supplemental Indenture and shall, to the extent applicable, be governed by such provisions. 

All things necessary have been done to make the Notes, when executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Company, and all things necessary have been done to make the Subsidiary Guarantees thereof, when the Notes have been executed by the Company and authenticated and delivered hereunder and duly
issued by the Company, the valid obligations of the Subsidiary Guarantors. All things necessary to make this Supplemental Indenture a valid agreement of each of the Company and the Subsidiary Guarantors, in accordance with its terms, have been done.

 “Weighted Average Life to Maturity” means, when applied to any Indebtedness
at any date, the number of years obtained by dividing: 
 (1) the sum of the products obtained by multiplying
(a) the amount of each then remaining installment, sinking fund, serial maturity or other required payments of principal, including payment at final maturity, in respect of the Indebtedness, by (b) the number of years (calculated to the
nearest one-twelfth) that will elapse between such date and the making of such payment; by 
 (2) the then
outstanding principal amount of such Indebtedness. 
 Section 202. Compliance Certificates and Opinions. 

Upon any application or request by the Company to the Trustee to take or refrain from taking any action under any provision of the
Indenture, the Company shall furnish to the Trustee such certificates and opinions as may be required under the Trust Indenture Act. Each such certificate or opinion shall be given in the form of an Officers’ Certificate, if to be given by an
Officer of the Company, or an Opinion of Counsel, if to be given by counsel, and shall comply with the requirements of the Trust Indenture Act and any other requirements set forth in the Indenture. 

Every certificate or opinion with respect to compliance with a condition or covenant provided for in the Indenture shall include,

 (1) a statement that each individual signing such certificate or opinion has read such covenant or condition
and the definitions herein relating thereto; 
 (2) a brief statement as to the nature and scope of the
examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; 
 (3) a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant

individual, such condition or covenant has been complied with. 
 Section 203. Form of Documents Delivered to Trustee. 

In any case where several matters are required to be certified by, or covered by an opinion of, any specified person, it is not necessary
that all such matters be certified by, or covered by the opinion of, only one such person, or that they be so certified or covered by only one document, but one such person may certify or give an opinion with respect to some matters and one or more
other such persons as to other matters, and any such person may certify or give an opinion as to such matters in one or several documents. 
 Any certificate or opinion of an Officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such Officer knows,
or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which his certificate or opinion is based are erroneous. Any such certificate or opinion of counsel may be based,
insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an Officer or Officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless
such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous. 
 Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under the Indenture, they may, but need not, be
consolidated and form one instrument. 

  
 31 

 Section 204. Acts of Holders; Record Dates. 

Any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by the Indenture to be
given, made or taken by Holders of the Notes may be embodied in and evidenced by one or more instruments of substantially similar tenor signed (either physically or by means of a facsimile or an electronic transmission, provided that such
electronic transmission is transmitted through the facilities of a Depositary) by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such
instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Company or the Subsidiary Guarantors. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the “Act” of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of the Indenture and
conclusive in favor of the Trustee and the Company and, if applicable, the Subsidiary Guarantors, if made in the manner provided in this Section. 
 The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer
authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other
manner which the Trustee deems sufficient. 
 The ownership, principal amount and serial numbers of Notes held by any Person,
and the date of commencement of such Person’s holding of same, shall be proved by the Security Register. 
 Any request,
demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of Notes and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu
thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company or, if applicable, the Subsidiary Guarantors in reliance thereon, whether or not notation of such action is made upon such Note. 

The Company may set any day as a record date for the purpose of determining the Holders of Outstanding Notes entitled to give, make or
take any request, demand, authorization, direction, notice, consent, waiver or other Act provided or permitted by the Indenture to be given, made or taken by Holders of Notes, provided that the Company may not set a record date for, and the
provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in the next paragraph. If any record date is set pursuant to this paragraph, the Holders of Outstanding
Notes on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date; provided that no such action shall be effective hereunder unless taken on or
prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to prevent the Company from setting a new record date for any action for
which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to
render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Company, at its own expense, shall cause
notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Trustee in writing and to each Holder of Notes in the manner set forth in Section 206. 

The Trustee may set any day as a record date for the purpose of determining the Holders of Notes entitled to join in the giving or making
of (1) any Notice of Default, (2) any declaration of acceleration referred to in Section 602, (3) any request to institute proceedings referred to in Section 607(2) or (4) any direction referred to in Section 612. If any record date is set pursuant
to this paragraph, the Holders of Outstanding Notes on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date; provided
that no such action shall be effective hereunder unless taken on or prior to the applicable Expiration Date by Holders of the requisite principal amount of Outstanding Notes on such record date. Nothing in this paragraph shall be construed to
prevent the Trustee from setting a new record date for 

  
 32 

 
any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled
and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of Outstanding Notes on the date such action is taken. Promptly after any record date is set
pursuant to this paragraph, the Trustee, at the Company’s expense, shall cause notice of such record date, the proposed action by Holders and the applicable Expiration Date to be given to the Company in writing and to each Holder of Notes in
the manner set forth in Section 206. 
 With respect to any record date set pursuant to this Section, the party hereto
which sets such record date may designate any day as the “Expiration Date” and from time to time may change the Expiration Date to any earlier or later day; provided that no such change shall be effective unless notice of the
proposed new Expiration Date is given to each other party hereto in writing, and to each Holder of Notes in the manner set forth in Section 206, on or prior to the existing Expiration Date. If an Expiration Date is not designated with respect
to any record date set pursuant to this Section, the party hereto which set such record date shall be deemed to have initially designated the 180th day after such record date as the Expiration Date with respect thereto, subject to its right to
change the Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no Expiration Date shall be later than the 180th day after the applicable record date. 
 Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to the Notes may do so with regard to all or any part of the principal amount of such Note or by one or
more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. 

Section 205. Notices, Etc., to Trustee and Company. 
 Any request, demand, authorization, direction, notice, consent, waiver or other Act of Holders or other document provided or permitted by the Indenture to be made upon, given or furnished to, or filed
with, 
 (1) the Trustee by any Holder or by the Company or by any Subsidiary Guarantor shall be sufficient for
every purpose hereunder if made, given, furnished or filed in writing in the English language to or with the Trustee at its Corporate Trust Office, Attention: Corporate Trust Services, or 

(2) the Company or the Subsidiary Guarantors by the Trustee or by any Holder shall be sufficient for every purpose
hereunder (unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, addressed to the Company at the address of its principal office specified in the first paragraph of this instrument
or at any other address previously furnished in writing to the Trustee by the Company or the Subsidiary Guarantors. 
 Section 206.
Notice to Holders; Waiver. 
 Where the Indenture provides for notice to Holders of any event, such notice shall be
sufficiently given (unless otherwise herein expressly provided) if in writing in the English language and mailed, first-class postage prepaid, to each Holder affected by such event, at his address as it appears in the Security Register, not later
than the latest date (if any), and not earlier than the earliest date (if any), prescribed for the giving of such notice. In any case where notice to Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so
mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. If notice is mailed to Holders in the manner provided in this Section 206, it is duly given, whether or not the addressee receives it.
Where the Indenture provides for notice in any manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such waiver shall be the equivalent of such notice. Waivers of notice by
Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. 
 When the Notes are not Global Notes, in case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. 

  
 33 

 Section 207. Conflict with Trust Indenture Act. 

If any provision hereof limits, qualifies or conflicts with a provision of the Trust Indenture Act which is required under the Trust
Indenture Act to be a part of and govern the Indenture, the latter provision shall control. If any provision of the Indenture modifies or excludes any provision of the Trust Indenture Act which may be so modified or excluded, the latter provision
shall be deemed to apply to the Indenture as so modified or to be excluded, as the case may be. 
 Section 208. Effect of Headings and
Table of Contents. 
 The Article and Section headings herein and the Table of Contents are for convenience only and shall
not affect the construction hereof. 
 Section 209. Successors and Assigns. 

All covenants and agreements in the Indenture by the Company, the Subsidiary Guarantors or the Trustee shall bind their respective
successors and assigns, whether so expressed or not. 
 Section 210. Separability Clause. 

In case any provision in the Indenture (including the Subsidiary Guarantees) or the Notes shall be invalid, illegal or unenforceable, the
validity, legality and enforce ability of the remaining provisions shall not in any way be affected or impaired thereby. 
 Section 211.
Benefits of Indenture. 
 Nothing in the Indenture (including the Subsidiary Guarantees) or the Notes, express or
implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders, any benefit or any legal or equitable right, remedy or claim under the Indenture. 

Section 212. Governing Law. 
 This Supplemental Indenture, the Indenture, the Notes and the Subsidiary Guarantees shall be governed by and construed in accordance with the laws of the State of New York. 

Section 213. Legal Holidays. 
 In any case where any Interest Payment Date, Redemption Date, purchase date or Stated Maturity of any Note shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of
the Indenture or of the Notes (other than a provision of any Note which specifically states that such provision shall apply in lieu of this Section)) payment of interest or principal (and premium, if any) 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, Redemption Date or purchase date, or at the Stated Maturity. 

Section 214. No Personal Liability of Directors, Officers, Employees and Stockholders. 

No director, officer, employee, incorporator, stockholder, member, manager or partner of the Company or any Subsidiary Guarantor, as
such, shall have any liability for any obligations of the Company or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect of, or by reason of, such obligations or their creation.
Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

  
 34 

 Section 215. No Adverse Interpretation of Other Agreements. 

The Indenture may not be used to interpret any other indenture, loan or debt agreement of the Company or its Subsidiaries or of any other
Person. Any such indenture, loan or debt agreement may not be used to interpret the Indenture. 
 Section 216. U.S.A. Patriot Act.

 The parties hereto acknowledge that in accordance with Section 326 of the U.S.A. Patriot Act, the Trustee, like all
financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account
with the Trustee. The parties to this Supplemental Indenture agree that they will provide the Trustee with such information within their possession or control as it may reasonably request in order for the Trustee to satisfy the requirements of the
U.S.A. Patriot Act. 
 Section 217. Force Majeure. 
 In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its
control, including strikes, work stoppages, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer
(software and hardware) services; it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

copies of this Supplemental Indenture and of signature pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Supplemental Indenture as to the parties hereto and may be used in lieu of the original
Supplemental Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall be deemed to be their original signatures for all purposes.

 ARTICLE FOUR 
 THE NOTES 

Section 401. Title and Terms. 
 The Notes shall be entitled the “7.00% Senior Notes due 2021.” The Trustee shall authenticate the Notes to be authenticated and delivered under this Supplemental Indenture on the Issue Date in
an aggregate amount equal to $250,000,000, upon delivery of a Company Order. The Trustee shall authenticate Additional Notes thereafter from time to time in unlimited amount for original issue upon receipt of a Company Order (subject to compliance
with Section 1111). Any such Company Order shall also specify the date on which the original issue of Notes is to be authenticated and, in relation to any Additional Notes, it shall also specify the principal amount thereof to be issued and
shall certify that such issuance is not prohibited by Section 1111. 
 The Notes will mature on June 15, 2021.
Interest on the Notes will accrue at the rate of 7.00% per annum and will be payable semiannually in cash on each June 15 and December 15, commencing on December 15, 2013, in the case of the Initial Notes, to the Persons who are

 36 

 Section 403. Execution, Authentication, Delivery and Dating. 

The Notes shall be executed on behalf of the Company by its Chairman of the Board, its Vice Chairman of the Board, its President or one
of its Vice Presidents. If its corporate seal is reproduced thereon, it shall be attested by the Secretary or an Assistant Secretary of the Company. The signature of any of these officers on the Notes may be manual or facsimile. 

If the Company elects to reproduce its corporate seal on the Notes, then such seal may be in the form of a facsimile thereof and may be
impressed, affixed, imprinted or otherwise reproduced on the Notes. 
 Notes bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind the Company, notwithstanding the fact that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did
not hold such offices at the date of such Notes. 
 At any time and from time to time after the execution and delivery of this
Supplemental Indenture and as provided in Section 401, the Company may deliver Notes executed by the Company to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in
accordance with the Company Order shall authenticate and deliver such Notes. 
 Each Note shall be dated the date of its
authentication. 
 No Note shall be entitled to any benefit under the Indenture or be valid or obligatory for any purpose unless
there appears on such Note a certificate of authentication substantially in the form provided for in Annex A, signed manually in the name of the Trustee by an authorized signatory, and such certificate upon any Note shall be conclusive evidence, and
the only evidence, that such Note has been duly authenticated and delivered hereunder. Notwithstanding the foregoing, if any Note shall have been authenticated and delivered hereunder but never issued and sold by the Company, and the Company shall
deliver such Note to the Trustee for cancellation as provided in Section 409, for all purposes of the Indenture such Note shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits of
the Indenture. 
 Section 404. Temporary Securities. 
 Pending the preparation of definitive Notes, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the
Officers executing such Notes may determine, as evidenced by their execution of such Notes. 
 If temporary Notes are issued,
the Company will cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes 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 Notes, the Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor one or more definitive Notes of any authorized denominations and of like tenor and aggregate principal amount. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under the Indenture as definitive
Notes. 
 Section 405. 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 a register (the register
maintained in such office or agency 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 Notes and of
transfers of Notes. The Trustee is hereby appointed “Security Registrar” for the purpose of registering Notes and transfers of Notes as herein provided, and its Corporate Trust Office is the initial office or agency where the Securities
Register will be maintained. The Company may at any time replace such Security 

  
 37 

 
Registrar, change such office or agency or act as its own Security Registrar; provided, however, that there shall be only one Security Register. 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 Note at the office of the Security Registrar, Company shall execute and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes, of any authorized
denominations and of like tenor and aggregate principal amount. 
 All Notes issued upon any registration of transfer or
exchange of Notes shall be the valid obligations of the Company evidencing the same debt, and entitled to the same benefits under the Indenture, as the Notes surrendered upon such registration of transfer or exchange. 

Every Note 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 its attorney duly authorized in writing. 

No service charge shall be made for any registration of transfer or exchange of Notes, but the Company may require payment of a sum
sufficient to cover any transfer tax or other governmental taxes and fees that may be required by law or imposed by the Indenture in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to
Section 404, 1006, 1110, 1115 or 1208 not involving any transfer. 
 If the Notes are to be redeemed in part, the Company
shall not be required (1) to register the transfer of or exchange any Notes during a period of 15 days before a selection of Notes for redemption under Section 1204, or (2) to register the transfer of or exchange any Note so selected
for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part. 
 The provisions of
clauses (1), (2), (3) and (4) below shall apply only to Global Notes: 
 (1) Each Global Note
authenticated under the Indenture shall be registered in the name of the Depositary designated for such Global Note or a nominee thereof and delivered to such Depositary or a nominee thereof or custodian therefor, and each such Global Note shall
constitute a single Note for all purposes of the Indenture. 
 (2) Notwithstanding any other provision in the
Indenture, no Global Note may be exchanged in whole or in part for Notes registered, and no transfer of a Global Note in whole or in part may be registered, in the name of any Person other than the Depositary for such Global Note or a nominee
thereof, unless (A) such Depositary (i) has notified the Company that it is unwilling or unable to discharge its responsibilities properly as Depositary for such Global Note or (ii) has ceased to be a clearing agency registered under
the Exchange Act, and in either case the Company has not appointed a qualified successor within 90 days, (B) a Default or an Event of Default has occurred and is continuing and the Depositary has notified the Company and the Trustee of its
decision to exchange such Global Note for Notes in certificated form or (C) subject to the Depositary’s rules, the Company, at its option, has elected to terminate the book-entry system through the Depositary. 

(3) Subject to clause (2) above, any exchange of a Global Note for other Notes may be made in whole or in part, and
all Notes issued in exchange for a Global Note or any portion thereof shall be registered in such names as the Depositary for such Global Note shall direct. 
 (4) Every Note authenticated and delivered upon registration of transfer of, or in exchange for or in lieu of, a Global Note or any portion thereof, whether pursuant to this Section, Section 404,
406, 1006, 1110, 1115 or 1208 or otherwise, shall be authenticated and delivered in the form of, and shall be, a Global Note, unless such Note is registered in the name of a Person other than the Depositary for such Global Note or a nominee thereof.

  
 38 

 The Depositary for a Global Note may surrender such Global Note in exchange in whole or in
part for Notes in definitive registered form on such terms as are acceptable to the Company, the Trustee and such Depositary. Thereupon, the Company and the Subsidiary Guarantors shall execute, and the Trustee, upon receipt of a Company Order for
the authentication and delivery of Notes in definitive registered form, shall authenticate and deliver, without service charge: 
 (1) to the Person specified by such Depositary a new Note or Notes, with a notation of the Subsidiary Guarantee executed by the Subsidiary Guarantors, 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 Note; and 
 (2) to such Depositary a new Global Note, with a notation of the Subsidiary Guarantee executed by the Subsidiary Guarantors, in a denomination equal to the difference, if any, between the principal amount
of the surrendered Global Note and the aggregate principal amount of Notes authenticated and delivered pursuant to clause (1) above. 
 Every Person who takes or holds any beneficial interest in a Global Note agrees that: 
 (1) the Company, the Subsidiary Guarantors and the Trustee may deal with the Depositary as sole owner of the Global Note and as the authorized representative of such Person; 

(2) such Person’s rights in the Global Note shall be exercised only through the Depositary and shall be limited to
those rights established by law and agreement between such Person and the Depositary and/or direct and indirect participants of the Depositary; 
 (3) 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
Notes to, such Persons in accordance with their own procedures; and 
 (4) none of the Company, the Subsidiary
Guarantors, 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 Note or for maintaining, supervising
or reviewing any records relating to such beneficial ownership interests. 
 Section 406. Mutilated, Destroyed, Lost and Stolen
Notes. 
 If any mutilated Note is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 
 If there shall be delivered to the Company and the Trustee (1) evidence to their satisfaction of the destruction, loss or theft of any Note and (2) such security or indemnity as may be required
by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Note has been acquired by a protected purchaser, the Company shall execute and the Trustee shall
authenticate and deliver, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding. 

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Company in its
discretion may, instead of issuing a new Note, pay such Note. 
 Upon the issuance of any new Note 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. 

  
 39 

 Every new Note issued pursuant to this Section in lieu of any destroyed, lost or stolen Note
shall constitute an original additional contractual obligation of the Company whether or not the destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall be entitled to all the benefits of the Indenture equally and
proportionately with any and all other Notes 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 Notes. 
 Section 407. Payment of Interest; Interest Rights Preserved. 

Interest on any Note 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 Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest. 
 Any interest on any Note 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 (1) or (2) below: 

(1) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their
respective Predecessor Notes) 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 Note 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 given to each Holder of Notes in the manner set forth in Section 206, 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 sent, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record
Date and shall no longer be payable pursuant to the following clause (2). 
 (2) The Company may make payment of
any Defaulted Interest on the Notes in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Notes 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 Note delivered under the Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to
interest accrued and unpaid, and to accrue, which were carried by such other Note. 
 Section 408. Persons Deemed Owners.

 Prior to due presentment of a Note for registration of transfer, the Company, the Subsidiary Guarantors, the Trustee and any
agent of the Company, the Subsidiary Guarantors or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of and any premium and (subject to
Section 407) any interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Company, the Subsidiary Guarantors, the Trustee nor any of their respective agents shall be affected by notice to
the contrary. 

  
 40 

 Section 409. Cancellation. 

All Notes surrendered for payment, redemption, purchase, registration of transfer or exchange shall, if surrendered to any Person other
than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Company may at any time deliver to the Trustee for cancellation any Notes 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 Notes previously authenticated hereunder which the Company has not issued and sold, and all Notes so delivered shall
be promptly cancelled by the Trustee. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by the Indenture. All cancelled Notes held by the Trustee shall be
disposed of in accordance with the Trustee’s standard provisions or as directed by a Company Order. 
 Section 410. Computation of
Interest. 
 Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. 

Section 411. 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 FIVE 
 SATISFACTION AND DISCHARGE 
 Section 501. Satisfaction and Discharge of
Indenture. 
 The Indenture shall cease to be of further effect as to all Notes issued hereunder, and the Trustee, at the
expense of the Company upon Company Request, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when 
 (1) either 
 (a) all Notes theretofore authenticated and delivered
(other than (i) Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 406 and (ii) Notes for whose payment money has theretofore been deposited in trust or segregated and held in
trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 1103), have been delivered to the Trustee for cancellation; or 

(b) all such Notes not theretofore delivered to the Trustee for cancellation 

(i) have become due and payable, or 

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

  
 41 

 (iii) are to be called for redemption within one year under arrangements
satisfactory to the Trustee for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Company, 
 and the Company or any Subsidiary Guarantor in the case of (i), (ii) or (iii) of subclause (b) of this Section 501(1), has irrevocably deposited or caused to be irrevocably deposited
with the Trustee as trust funds in trust solely for such purpose cash in Dollars, non-callable Government Securities, or a combination thereof in such amounts as will be sufficient, without consideration of any reinvestment of interest, to pay and
discharge the entire indebtedness on such Notes not theretofore delivered to the Trustee for cancellation, for principal and any premium and interest to the date of such deposit (in the case of Notes which have become due and payable) or to the
Stated Maturity or Redemption Date, as the case may be; 
 (2) no Default or Event of Default has occurred and is
continuing on the date of the deposit (other than a Default or Event of Default resulting from the borrowing of funds to be applied to such deposit or the grant of liens securing such borrowing); 

(3) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or
instrument (other than the Indenture) to which the Company or any Subsidiary Guarantor is a party or by which the Company or any Subsidiary Guarantor is bound; 
 (4) the Company or any Subsidiary Guarantor has paid or caused to be paid all sums payable by it under the Indenture; 

(5) the Company has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of
the Securities at their Stated Maturity or on the Redemption Date, as the case may be; and 
 (6) the Company has
delivered to the Trustee (i) an Officers’ Certificate, stating that all conditions precedent set forth in clauses (1) through (5) above have been satisfied, and (ii) an Opinion of Counsel, stating that all conditions
precedent set forth in clauses (3) and (5) above have been satisfied. 
 Notwithstanding the satisfaction and discharge of the
Indenture in respect of the Notes, the obligations of the Company to the Holders under Sections 405 and 406, the obligations of the Company to the Trustee under Section 707, the obligations of the Trustee to any Authenticating Agent under
Section 714 and, if cash or Government Securities shall have been deposited with the Trustee pursuant to subclause (b) of clause (1) of this Section, the obligations of the Trustee under Section 502 and the last paragraph of
Section 1103 shall survive. 
 Section 502. Application of Trust Money. 

Subject to the provisions of the last paragraph of Section 1103, all cash and Government Securities (including the proceeds thereof)
deposited with the Trustee pursuant to Section 501 shall be held in trust and applied by it, in accordance with the provisions of the Notes and the 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 whose payment such cash and Government Securities (including the proceeds thereof) have been deposited
with the Trustee. 
 If the Trustee or Paying Agent is unable to apply any money or Government Securities in accordance with
Section 501 by reason of any legal proceeding or by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Company’s and any Subsidiary Guarantor’s
obligations under the Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 501; provided that if the Company has made any payment of principal of, premium, if any, or interest on,
any Notes because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent. 

  
 42 

 ARTICLE SIX 
 REMEDIES 
 Section 601. Events of Default. 

An “Event of Default,” wherever used herein, means any one of the following events in relation to the Notes (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): 
 (1) default in the payment of any interest upon any Note when it becomes due and payable, and
continuance of such default for a period of 30 days; 
 (2) default in the payment of the principal of or any
premium on any Note when due at its Stated Maturity, upon optional redemption, upon required repurchase, upon declaration of acceleration or otherwise; 
 (3) failure by the Company to comply with its obligations under Article Nine of this Supplemental Indenture or to consummate a purchase of Notes when required pursuant to Section 1110 or
Section 1115 of this Supplemental Indenture; 
 (4) failure by the Company or any Restricted Subsidiary for
30 days after receipt of a written notice (specifying such failure, requiring it to be remedied and stating that such notice is a “Notice of Default” under the Indenture) from the Trustee or the Holders of at least 25% in aggregate
principal amount of the then Outstanding Notes to comply with Section 1111 or Section 1112 of this Supplemental Indenture or to comply with the provisions described under Section 1110 or Section 1115 of this Supplemental
Indenture to the extent not described in clause (3) of this Section 601; 
 (5) failure by the Company
or any Restricted Subsidiary for 60 days (or 180 days in the case of a Reporting Failure) after receipt of a written notice (specifying such failure, requiring it to be remedied and stating that such notice is a “Notice of Default” under
the Indenture) from the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes to comply with any of the other agreements in the Indenture or the Notes; 

(6) default under any mortgage, indenture or instrument under which there may be issued or by which there may be secured
or evidenced any Indebtedness for money borrowed by the Company or any Restricted Subsidiary (or the payment of which is Guaranteed by the Company or any Restricted Subsidiary), whether such Indebtedness or Guarantee now exists, or is created after
the Issue Date, if that default: 
 (a) is caused by a failure to pay principal of, or interest or premium, if
any, on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (“Payment Default”); or 
 (b) results in the acceleration of such Indebtedness prior to its Stated Maturity; 

and, in each case, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under
which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $15.0 million or more; 
 (7) failure by the Company or any Significant Subsidiary or any group of the Company’s Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the
Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary to pay final judgments aggregating in excess of $15.0 million (net of any amounts covered by a reputable and creditworthy insurance company that has not disclaimed
coverage) which judgments are not paid, discharged or stayed for a period of 60 days; 

  
 43 

 (8) except as permitted by the Indenture, any Subsidiary Guarantee is held
in a judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full force and effect, or any Subsidiary Guarantor, or any Person acting on behalf of any Subsidiary Guarantor, denies or disaffirms its obligations under its
Subsidiary Guarantee; 
 (9) the Company, any Significant Subsidiary or any group of Restricted Subsidiaries
that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, pursuant to or within the meaning of Bankruptcy Law: 

(a) commences a voluntary case; 
 (b) consents to the entry of an order for relief against it in an involuntary case; 
 (c) makes a general assignment for the benefit of its creditors; or 

(d) generally is not paying its debts as they become due; or 

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

(a) is for relief against the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, in an involuntary case; or 

(b) appoints a custodian of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary, or for all or substantially all of the property of the Company, any Significant
Subsidiary or any group of Restricted Subsidiaries that, taken together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; or 

(c) orders the liquidation of the Company, any Significant Subsidiary or any group of Restricted Subsidiaries that, taken
together (as of the latest audited consolidated financial statements for the Company and its Restricted Subsidiaries), would constitute a Significant Subsidiary; 
 and the order or decree remains unstayed and in effect for 60 consecutive days. 

Section 602. Acceleration of Maturity; Rescission and Annulment. 
 In the case of an Event of Default specified in Section 601(9) or 601(10), all then Outstanding Notes will become due and payable immediately without further action or notice. If any other Event of
Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all of the Notes to be due and payable immediately by notice in writing to the Company and, in case
of a notice by Holders, also to the Trustee specifying the respective Event of Default and that it is a notice of acceleration. Upon any such declaration, the Notes shall become due and payable immediately. 

At any time after such a declaration of acceleration with respect to the Notes has been made, the Holders of at least a majority in
aggregate principal amount of the Outstanding Notes, by written notice to the Company and the Trustee, may rescind and annul such declaration and its consequences if 

  
 44 

 (1) such rescission would not conflict with any judgment or decree of a
court of competent jurisdiction; 
 (2) the Company has paid or deposited with the Trustee a sum sufficient to
pay 
 (a) all overdue interest on all the Notes, 

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

(3) all Events of Default with respect to the Notes, other than the non-payment of the principal of, premium, if any, and
interest on the Notes that have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 613. 
 Notwithstanding the foregoing, if an Event of Default specified in Section 601(6) above shall have occurred and be continuing, such Event of Default and any consequential acceleration (to the extent
not in violation of any applicable law or in conflict with any judgment or decree of a court of competent jurisdiction) shall be automatically rescinded if (1) the Indebtedness that is the subject of such Event of Default has been repaid or
(2) if the default relating to such Indebtedness is waived by the holders of such Indebtedness or cured and if such Indebtedness has been accelerated, then the holders thereof have rescinded their declaration of acceleration in respect of such
Indebtedness, in each case within 30 days after the declaration of acceleration with respect thereto, and (3) any other existing Events of Default, except nonpayment of principal, premium or interest on the Notes that became due solely because
of the acceleration of the Notes, have been cured or waived. 
 No such rescission shall affect any subsequent default or impair
any right consequent thereon. 
 Section 603. Collection of Indebtedness and Suits for Enforcement by Trustee. 

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

Section 604. Trustee May File Proofs of Claim. 
 In case of any judicial proceeding relative to the Company, the Subsidiary Guarantors or any other obligor upon the Notes, or the property or creditors of the Company or the Subsidiary Guarantors, the
Trustee shall be entitled and empowered, by intervention in such proceeding or otherwise, to take any and all actions authorized under the Trust Indenture Act in order to have claims of the Holders and the Trustee allowed in any such proceeding. In
particular, the Trustee shall be authorized to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same; and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other
similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee
any amount due it for the compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 707. 

  
 45 

 No provision of the Indenture shall be deemed to authorize the Trustee to authorize or
consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes 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 605. Trustee May Enforce Claims Without Possession of Notes. 

All rights of action and claims under the Indenture or the Notes may be prosecuted and enforced by the Trustee without the possession of
any of the Notes 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 compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, be for the ratable benefit of the Holders of the Notes in respect of which such judgment has been recovered. 

Section 606. Application of Money Collected. 
 Any money collected by the Trustee pursuant to this Article 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 Notes 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 707; 

SECOND: To the payment of the amounts then due and unpaid for principal of and any premium and interest on the Notes,
ratably, without preference or priority of any kind, according to the amounts due and payable on such Notes for principal and any premium and interest, respectively; and 

THIRD: The remainder, if any, shall be paid to the Subsidiary Guarantors or the Company, as applicable, or to whomsoever
may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. 
 Section 607. Limitation on
Suits. 
 No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to the Indenture,
or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless: 
 (1) such Holder
has previously given written notice to the Trustee of a continuing Event of Default with respect to the Notes; 

(2) the Holders of not less than 25% in aggregate principal amount of the Outstanding Notes shall have made written
request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder; 
 (3) such Holder or Holders have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities to be incurred in compliance with such request;

 (4) the Trustee for 60 days after its receipt of such notice, request and offer of security or indemnity has
failed to institute any such proceeding; and 
 (5) the Holders of at least a majority in aggregate principal
amount of the Outstanding Notes have not waived such Event of Default or otherwise given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with such request within such 60-day period; 

  
 46 

 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 the 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 the Indenture, except in the manner herein provided and for the equal and ratable benefit of all of such Holders. 

Section 608. Unconditional Right of Holders to Receive Principal, Premium and Interest. 

Notwithstanding any other provision in the Indenture, the Holder of any Notes shall have the right, which is absolute and unconditional,
to receive payment of the principal of and any premium and (subject to Section 407) interest on such Notes on the Stated Maturity expressed in such Notes (or, in the case of redemption or offer by the Company to purchase the Notes pursuant to
the terms of the Indenture, on the Redemption Date or purchase date, as applicable), 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 609. Restoration of Rights and Remedies. 
 If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under the 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 Subsidiary 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. 
 Section 610. Rights and Remedies Cumulative. 
 Except as otherwise
provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in the last paragraph of Section 406, 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 611. Delay or Omission Not Waiver. 
 No delay or omission of
the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be. 
 Section 612. Control by Holders. 
 Subject to Section 703(5), the
Holders of at least a majority in aggregate principal amount of the Outstanding Notes 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 Notes, provided that 
 (1) the Trustee may refuse to follow
any direction that conflicts with any rule of law or with the Indenture or that the Trustee determines is unduly prejudicial to the rights of any other Holder or would involve the Trustee in personal liability, and 

(2) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

  
 47 

 Section 613. Waiver of Past Defaults. 

The Holders of at least a majority in aggregate principal amount of the Outstanding Notes may on behalf of the Holders of all the Notes
waive any past default hereunder and its consequences or compliance with any covenant or provision hereof, except a default 
 (1) in the payment of the principal of or any premium or interest on the Notes (including any Note which is required to have been purchased by the Company pursuant to an offer to purchase by the Company
made pursuant to the terms of the Indenture), or 
 (2) in respect of a covenant or provision hereof which under
Article Ten cannot be modified or amended without the consent of the Holder of each Outstanding Note affected. 
 Upon any such
waiver with respect to a past default, such default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured, for every purpose of the Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon. 
 Section 614. Undertaking for Costs. 

In any suit for the enforcement of any right or remedy under the Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, a court may require any party litigant in such suit to file an undertaking to pay the costs of such suit, and may assess costs against any such party litigant, in the manner and to the extent provided in the
Trust Indenture Act; provided that neither this Section nor the Trust Indenture Act shall be deemed to authorize any court to require such an undertaking or to make such an assessment in any suit instituted by the Company. 

Section 615. Waiver of Usury, Stay or Extension Laws. 
 Each of the Company and the Subsidiary 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 usury, stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of the Indenture; and the Company (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. 
 ARTICLE SEVEN 
 THE TRUSTEE 
 Section 701. Certain Duties and Responsibilities. 

The duties and responsibilities of the Trustee shall be as provided by Section 315 of the Trust Indenture Act. Notwithstanding the
foregoing, no implied covenants shall be read into the Indenture against the Trustee, and no provision of the 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. Whether or
not therein expressly so provided, every provision of the Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject to the provisions of this Section. 

Section 702. Notice of Defaults. 
 Within 90 days after the occurrence of any Default with respect to the Notes and is deemed to be known to the Trustee, the Trustee shall send to all Holders of Notes, as their names and addresses
appear in the Security Register, notice of such Default known to the Trustee, unless such Default shall have been cured or waived; provided,  

  
 48 

 
however, that, except in the case of a Default in the payment of the principal of or any premium or interest with respect to any Note, the Trustee may withhold from Holders of Notes notice
of any continuing Default or Event of Default if the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders of Notes; and, provided, further, that (1) in the case of any Default of
the character specified in Section 601(4), no such notice to Holders shall be given until at least 30 days after the occurrence thereof, and (2) in the case of any Default of the character specified in Section 601(5), no such notice
to Holders shall be given until at least 60 days after the occurrence thereof. 
 Section 703. Certain Rights of Trustee.

 Subject to the provisions of Section 701: 

(1) the Trustee may rely and shall be protected in acting or refraining from acting upon any resolution, certificate,
statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document believed by it to be genuine and to have been signed or presented by the proper
party or parties; 
 (2) any request or direction of the Company mentioned herein shall be sufficiently evidenced
by a Company Request or Company Order, and any resolution of the Board of Directors shall be sufficiently evidenced by a Board Resolution; 
 (3) whenever in the administration of the Indenture the Trustee shall deem it desirable that a matter be proved or established prior to taking, suffering or omitting any action hereunder, the Trustee
(unless other evidence be herein specifically prescribed) may, in the absence of bad faith on its part, rely upon an Officers’ Certificate; 
 (4) the Trustee may consult with counsel and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or
omitted by it hereunder in good faith and in reliance thereon; 
 (5) the Trustee shall be under no obligation to
exercise any of the rights or powers vested in it by the Indenture at the request or direction of any of the Holders pursuant to the Indenture, unless such Holders shall have offered to the Trustee reasonable security or indemnity against the costs,
expenses and liabilities which might be incurred by it in compliance with such request or direction; 
 (6) the
Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of
indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or
investigation, it shall be entitled to examine the books, records and premises of the Company, personally or by agent or attorney; 
 (7) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either directly or by or through agents or attorneys and the Trustee shall not be responsible for any
misconduct or negligence on the part of any agent or attorney appointed with due care by it hereunder; 
 (8) the
Trustee may request that the Company and, if applicable, the Subsidiary Guarantors deliver an Officers’ Certificate setting forth the names of individuals or titles of officers authorized at such time to take specified actions pursuant to the
Indenture, which Officers’ Certificate may be signed by any person authorized to sign an Officers’ Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded; 

(9) the Trustee shall not be deemed to have notice or be charged with knowledge of any Default or Event of Default unless
a Responsible Officer of the Trustee has received written notice of any event that is in fact such a Default or Event of Default at the Corporate Trust Office of the Trustee, and such notice references the Notes and the Indenture; 

  
 49 

 (10) the Trustee shall not be liable for any action taken, suffered, or
omitted to be taken by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by the Indenture; 
 (11) the rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the
Trustee in each of its capacities hereunder, and each agent, custodian and other Person employed to act under the Indenture; and 
 (12) anything in the Indenture notwithstanding, in no event shall the Trustee be liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever (including but not limited to
loss of profit), even if the Trustee has been advised as to the likelihood of such loss or damage and regardless of the form of action. 

Section 704. Not Responsible for Recitals or Issuance of Notes. 
 The recitals contained herein and in the Notes, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no representations as to the validity or sufficiency of the Indenture or of the Notes. Neither the Trustee nor any Authenticating Agent shall be accountable for the use or
application by the Company of Notes or the proceeds thereof. 
 Section 705. May Hold Notes. 

The Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company, in its individual or
any other capacity, may become the owner or pledgee of Notes and, subject to Sections 708 and 713, may otherwise deal with the Company with the same rights it would have if it were not Trustee, Authenticating Agent, Paying Agent, Security Registrar
or such other agent. 
 Section 706. Money Held in Trust. 
 Money and Government Securities held by the Trustee in trust hereunder need not be segregated from other funds except to the extent required by law. The Trustee shall be under no liability for interest on
any money received by it hereunder except as otherwise agreed with the Company. 
 Section 707. Compensation and Reimbursement.

 The Company agrees 
 (1) to pay to the Trustee from time to time 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); 
 (2) except as otherwise expressly provided herein, to reimburse the Trustee upon
its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of the Indenture (including the reasonable compensation and the expenses and disbursements of its agents and
counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and 
 (3) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense incurred without gross negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of the trust or trusts hereunder, including the costs and expenses of defending itself 

  
 50 

 
against any claim or liability in connection with the exercise or performance of any of its powers or duties hereunder. When the Trustee incurs expenses or renders services after the occurrence
of an Event of Default specified in paragraph (9) or (10) of Section 601, such expenses and the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy Law. 

The obligations of the Company and the Subsidiary Guarantors under this Section 707 shall survive the satisfaction and discharge of
the Indenture. 
 To secure the Company’s and the Subsidiary Guarantors’ payment obligations in this Section 707,
the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular Notes. Such Lien shall survive the satisfaction and discharge of the
Indenture. 
 “Trustee” for purposes of this Section shall include any predecessor Trustee; provided,
however, that the negligence or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder. 

Section 708. Conflicting Interests. 
 If the Trustee has or shall acquire a conflicting interest within the meaning of the Trust Indenture Act after a Default has occurred and is continuing, the Trustee shall either eliminate such interest
within 90 days, apply to the SEC for permission to continue as trustee or resign. To the extent permitted by the Trust Indenture Act, the Trustee shall not be deemed to have a conflicting interest by virtue of being a trustee under the Base
Indenture with respect to Securities of more than one series. 
 Section 709. Corporate Trustee Required; Eligibility. 

There shall at all times be one (and only one) Trustee hereunder with respect to the Notes. Each Trustee shall be a Person that is
eligible pursuant to the Trust Indenture Act to act as such, and has a combined capital and surplus of at least $50,000,000. If any such Person publishes reports of condition at least annually, pursuant to law or to the requirements of its
supervising or examining authority, then for the purposes of this Section and to the extent permitted by the Trust Indenture Act, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in
its most recent report of condition so published. If at any time the Trustee with respect to the Notes shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article. 
 Section 710. Resignation and Removal; Appointment of Successor. 

No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until
the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 711. 

The Trustee may resign at any time with respect to the Notes by giving written notice thereof to the Company. If the instrument of
acceptance by a successor Trustee required by Section 711 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 Notes. 
 The Trustee may be removed at any time by Act of the Holders of
at least a majority in aggregate principal amount of the Outstanding Notes, delivered to the Trustee and to the Company. 
 If
at any time: 
 (1) the Trustee shall fail to comply with Section 708 after written request therefor by the
Company or by any Holder who has been a bona fide Holder of a Note for at least six months, or 

  
 51 

 (2) the Trustee shall cease to be eligible under Section 709 and shall
fail to resign after written request therefor by the Company or by any such Holder, or 
 (3) the Trustee shall
become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the
purpose of rehabilitation, conservation or liquidation, 
 then, in any such case, (a) the Company by a Board Resolution may remove the
Trustee, or (b) subject to Section 614, any Holder who has been a bona fide Holder of a Note 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 Notes and the appointment of a successor Trustee or Trustees. 
 If the Trustee shall resign,
be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause, with respect to the Notes, the Company, by a Board Resolution, shall within 60 days appoint a successor Trustee or Trustees with respect to
the Notes and shall comply with the applicable requirements of Section 711. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Notes shall be appointed
by Act of the Holders of at least a majority in aggregate principal amount of the Outstanding Notes 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 711, become the successor Trustee with respect to the Notes and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Notes
shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 711, any Holder who has been a bona fide Holder of a Note 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 Notes. 
 The Company shall give notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders of Notes in the manner provided in Section 206. Each
notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. 
 Section 711. Acceptance of
Appointment by Successor. 
 In case of the appointment hereunder of a successor Trustee, every such successor Trustee so
appointed shall execute, acknowledge and deliver to the Company 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 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. 
 Upon request of any such successor Trustee, the Company and the Subsidiary 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 the first or second preceding paragraph, as the case may be. 

No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and
eligible under this Article. 
 Section 712. 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, 

  
 52 

 
without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes 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 Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such
Notes. 
 Section 713. Preferential Collection of Claims Against Company. 

If and when the Trustee shall be or become a creditor of the Company or any other obligor upon the Notes, the Trustee shall be subject to
the provisions of the Trust Indenture Act regarding the collection of claims against the Company or any such other obligor. 
 Section 714.
Appointment of Authenticating Agent. 
 The Trustee may appoint an Authenticating Agent or Agents which shall be
authorized to act on behalf of the Trustee to authenticate Notes issued upon original issue and upon exchange, registration of transfer or partial redemption thereof or pursuant to Section 406, and Notes so authenticated shall be entitled to
the benefits of the Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Supplemental Indenture to the authentication and delivery of Notes 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 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. 
 An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. 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. 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 shall give notice of such appointment in the manner provided in Section 206 to all Holders of Notes with respect to which such Authenticating Agent will serve. 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. 
 The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its
services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, subject to the provisions of Section 707. 

  
 53 

 If an appointment with respect to one or more series is made pursuant to this Section, the
Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternative certificate of authentication in the following form: 
 This is one of the 7.00% Senior Notes due 2021 referred to in the within-mentioned Indenture.

conveyance or other disposition of all or substantially all of the properties or assets of one or more Subsidiaries of the Company, which properties or assets, if held by the Company instead of such Subsidiaries, would constitute all or
substantially all of the properties or assets of the Company on a consolidated basis, shall be deemed to be the transfer of all or substantially all of the properties or assets of the Company. 

  
 55 

 The surviving entity will succeed to, and be substituted for, and may exercise every right
and power of, the Company under the Indenture and the predecessor Company shall be discharged and released from all obligations under the Indenture and the Notes; provided, however, that the Company will not be released from the obligation to pay

to pay the principal of and interest on the Notes in the case of a lease of all or substantially all of the Company’s properties or assets in a transaction that is subject to, and that complies with the provisions of, Section 901.

than all series of Securities, stating that such covenants are expressly being included solely for the benefit of such series) or to surrender any right or power therein conferred upon the
Company or 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 the Indenture as set forth therein; provided, that in respect of any such additional covenant, restriction, condition or provision, such supplemental indenture may provide for a particular period of grace after Default (which period may be

 Section 1002. Supplemental Indentures With Consent of Holders. 

The Company, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture, the Securities Guarantees and the
Securities with the consent of the Holders of at least 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 608 and Section 613, any existing Default or Event of Default or
compliance with any provision of the Indenture, the Securities Guarantees or the Securities may be waived with respect to each series of Securities with the consent of the Holders of at least a majority in aggregate principal amount of the
Outstanding Securities of 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). 

Upon the request of the Company accompanied by a Board Resolution authorizing the execution of any such amended 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 1003, the Trustee will join
with the Company and the Subsidiary Guarantors in the execution of such amended or supplemental indenture unless such amended or supplemental indenture affects the Trustee’s own rights, duties or immunities under the Indenture or otherwise, in
which case the Trustee may in its discretion, but will not be obligated to, enter into such amended or supplemental Indenture. 

It is not necessary for the consent of the Holders of Securities under this Section 1002 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 1002 becomes effective, the Company shall send to the Holders of Securities affected thereby a notice briefly describing the amendment,
supplement or waiver. Any failure of the Company to give such notice, or any defect therein, will not, however, in any way impair or affect the validity of any such amended or supplemental indenture or waiver. 

Subject to Section 608 and Section 613, the application of or compliance with, either generally or in any particular instance,
any provision of the Indenture, the Securities or the Securities Guarantees may be waived as to each series of Securities by the Holders of at least a majority in aggregate principal amount of the Outstanding Securities of such series. However,
without the consent of each Holder affected, an amendment, supplement or waiver under this Section 1002 may not (with respect to any Securities held by a non-consenting Holder): 

(1) 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 602, or change any Place of Payment where, or 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 therefor); 
 (2) reduce the percentage in aggregate principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any such amendment, supplement or waiver; 

(3) modify any of the provisions of Section 608 or Section 613, except to increase any such percentage or to
provide that certain other provisions of the Indenture cannot be modified or waived without the consent of each Holder of each Outstanding Security affected thereby; 

(4) 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; 

  
 58 

 (5) release any Subsidiary Guarantor from any of its obligations under its
Subsidiary Guarantee or the Indenture, except in accordance with the terms of the Indenture (as supplemented by any supplemental indenture); or 
 (6) make any change in the foregoing amendment and waiver provisions. 
 A
supplemental indenture that changes or eliminates any covenant or other provision of the 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 the Indenture of the Holders of Securities of any other series. 
 Section 1003. Execution of Supplemental Indentures. 
 In executing, or
accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by the Indenture, the Trustee shall be entitled to receive, and shall be fully protected in relying
upon, an Officers’ Certificate and Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by the Indenture. 
 Section 1004. Effect of Supplemental Indentures. 
 Upon the execution
of any supplemental indenture under this Article, the Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of the Indenture for all purposes; and every Holder of Notes theretofore or thereafter
authenticated and delivered hereunder shall be bound thereby. 
 Section 1005. Conformity with Trust Indenture Act. 

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act. 

Section 1006. Reference in Notes to Supplemental Indentures. 
 Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as
to any matter provided for in such supplemental indenture. If the Company shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the
Company and such new Notes may be authenticated and delivered by the Trustee in exchange for Outstanding Notes. 
 Section 1007. Effect

 Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Security is a
continuing consent by the Holder of a Security and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent is not made on any Security. An
amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder. 
 ARTICLE
ELEVEN 
 COVENANTS 
 Section 1101. Payment of Principal, Premium and Interest. 
 The
Company covenants and agrees for the benefit of the Notes that it will duly and punctually pay the principal of and any premium and interest on the Notes in accordance with the terms of the Notes and the Indenture. Principal, premium, if any, and
interest will be considered paid on the date due if a Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11 a.m., New York City time, on the due date money deposited by the Company in immediately available funds and
designated for and sufficient to pay all principal, premium, if any, and interest then due. 

  
 59 

 The Company will pay interest (including post-petition interest in any proceeding under any
applicable Bankruptcy Law) on overdue principal and premium, if any, at the interest rate specified in the Notes to the extent lawful; and it will pay interest (including post-petition interest in any proceeding under any applicable Bankruptcy Law)
on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. 
 Section 1102.
Maintenance of Office or Agency. 
 The Company will maintain, in the City and State of New York and
in any other Place of Payment, an office or agency where Notes may be presented or surrendered for payment, and it will maintain an office or agency in the United States where Notes may be surrendered for registration of transfer or exchange and
where notices and demands to or upon the Company in respect of the Notes and the Indenture may be served. The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the Corporate Trust Office of the
Trustee, and the Company hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands. The Company hereby irrevocably designates as a Place of Payment for the Notes the City and State of New York, and
initially appoints Wells Fargo Bank National Association at its corporate trust office in the City of New York, which, at the date hereof, is located at 45 Broadway, 14th Floor, New York, New York 10006, Attn: Corporate Trust Administratoin, as the Company’s office or agency in such
city where the Notes may be presented or surrendered for payment. 
 The Company may also from time to time designate one or
more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any
manner relieve the Company of its obligation to maintain in the City and State of New York, a Place of Payment for the Notes. 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. 
 Section 1103. Money for Notes Payments to Be Held in Trust. 

If the Company shall at any time act as its own Paying Agent, it will, before 11 a.m., New York City time, on each due date of the
principal of or any premium or interest on any of the Notes, 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 the Notes, it will, prior to 11 a.m., New York City time, on each due date of the principal of or any premium or interest on the Notes,
deposit with a Paying Agent a sum sufficient to pay such amount, such sum to be held as provided by the Trust Indenture Act, and (unless such Paying Agent is the Trustee) the Company will promptly notify the Trustee of its action or failure so to
act. 
 The Company will cause each Paying Agent other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent will (1) comply with the provisions of the Trust Indenture Act applicable to it as a Paying Agent and (2) during the
continuance of any default by the Company or any other obligor upon the Notes in the making of any payment in respect of the Notes, upon the written request of the Trustee, forthwith pay to the Trustee all sums held in trust by such Paying Agent for
payment in respect of the Notes. 
 The Company may at any time, for the purpose of obtaining the satisfaction and discharge of
the 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. 

  
 60 

 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 any premium or interest on the Notes and remaining unclaimed for two years 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 Notes 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, if there are then outstanding any Notes not in global form, 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 a newspaper published in the English language, customarily published on each Business Day and of general circulation in the City and State of
New York 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 1104. Annual Compliance Certificate; Statement by Officers as to Default. 

The Company and the Subsidiary Guarantors shall deliver to the Trustee within 150 days after the end of each fiscal year of the Company
ending after the Issue Date an Officers’ Certificate signed by the principal executive officer, the principal accounting officer or the principal financial officer of each of the Company and the Subsidiary Guarantors, stating that a review of
the activities of the Company and its Restricted Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each of the Company and the Subsidiary Guarantors has
performed its obligations under the Indenture, and further stating whether or not the signers know of any Default or Event of Default that occurred during such period. If they do, the certificate shall describe such Default or Event of Default, its
status and what action the Company is taking or proposes to take with respect thereto. 
 The Company shall, so long as any Note
is Outstanding, deliver to the Trustee within five days after becoming aware of the occurrence of any Default or Event of Default, written notice (which need not be an Officers’ Certificate) setting forth the details of such Default or Event of
Default, and what action the Company is taking or proposing to take with respect thereto. 
 Section 1105. Existence. 

Subject to Article Nine, the Company will do or cause to be done all things necessary to preserve and keep in full force and effect the
existence, rights (charter and statutory) and franchises of the Company; provided, however, that the Company shall not be required to preserve any such right or franchise if it shall determine that the preservation thereof is no longer
desirable in the conduct of the business of the Company. 
 Section 1106. Reports. 

Regardless of whether required by the rules and regulations of the SEC, so long as any Notes are Outstanding, the Company will file with
the SEC for public availability, within the time periods specified in the SEC’s rules and regulations (unless the SEC will not accept such a filing, in which case the Company will comply with the requirements described in the next following
paragraph of this Section 1106): 
 (1) all quarterly and annual reports that would be required to be filed
with the SEC on Forms 10-Q and 10-K under the Exchange Act if the Company were required to file such reports; and 
 (2) all current reports that would be required to be filed with the SEC on Form 8-K under the Exchange Act if the Company were required to file such reports. 

  
 61 

 All such reports will be prepared in all material respects in accordance with all of the rules and
regulations applicable to such reports. Each annual report on Form 10-K will include a report on the Company’s consolidated financial statements by the Company’s certified independent accountants. 

If, at any time, the Company is no longer subject to the periodic reporting requirements of the Exchange Act for any reason, the Company
will nevertheless continue filing the reports specified in the first paragraph of this Section 1106 with the SEC within the time periods specified in the first paragraph of this Section 1106 unless the SEC will not accept such a filing.
The Company will not take any action for the purpose of causing the SEC not to accept any such filings. If, notwithstanding the foregoing, the SEC will not accept the Company’s filings for any reason, the Company will post the reports referred
to in the first paragraph of this Section 1106 on its website within the time periods that would apply if the Company were required to file those reports with the SEC. 
 If the Company has designated any of its Subsidiaries as Unrestricted Subsidiaries, then the quarterly and annual financial information required by the preceding paragraphs of this Section 1106 will
include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” of the financial
condition and results of operations of the Company and its Restricted Subsidiaries separate from the financial condition and results of operations of the Unrestricted Subsidiaries. 

In the event any direct or indirect parent company of the Company becomes a guarantor of the Notes, the Company may satisfy its
obligations in this Section 1106 with respect to financial information relating to the Company by furnishing financial information relating to such parent company; provided that the same is accompanied by consolidating information that
explains in reasonable detail the differences between the information relating to such parent, on the one hand, and the information relating to the Company and its Subsidiaries on a standalone basis, on the other hand. 

The availability of the foregoing materials on the SEC’s website or on a freely accessible page on the Company’s website shall
be deemed to satisfy the foregoing delivery obligations. 
 Delivery of the foregoing information, reports or certificates or
any annual reports, information, documents and other reports to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute constructive notice of any information therein or determinable from
information contained therein, including the Company’s compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). 

Section 1107. Payment of Taxes. 
 The Company shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency, any taxes, assessments, and governmental levies except such as are contested in good faith and by appropriate
proceedings or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes. 

Section 1108. [Reserved]. 

Section 1109. [Reserved]. 

Section 1110. Repurchase of Notes Upon a Change of Control. 
 If a Change of Control occurs, each Holder of Notes will have the right to require the Company to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess of $2,000) of that
Holder’s Notes pursuant to an offer (a “Change of Control Offer”) on the terms set forth in this Section 1110. In the Change of Control Offer, the Company will offer a payment in cash (the “Change of Control
Payment”) equal to not less than 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest, if any, on the Notes repurchased to the date of purchase (the “Change of Control Payment Date”),
subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. Within 30 days following any Change of Control, the Company will send a notice to each Holder describing the
transaction or transactions that constitute the Change of Control and stating: 

  
 62 

 (1) that the Change of Control Offer is being made pursuant to this
Section 1110 and that all Notes tendered will be accepted for payment; 
 (2) the purchase price and the
Change of Control Payment Date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent; 
 (3) that any Note not tendered will continue to accrue interest; 

(4) that, unless the Company defaults in the payment of the Change of Control Payment, all Notes accepted for payment
pursuant to the Change of Control Offer will cease to accrue interest after the Change of Control Payment Date; 

(5) that Holders electing to have any Notes purchased pursuant to a Change of Control Offer will be required to surrender
the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the
third Business Day preceding the Change of Control Payment Date; 
 (6) that Holders will be entitled to withdraw
their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the
principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election to have the Notes purchased; and 
 (7) that Holders whose Notes are being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry
transfer), which unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess of $2,000. 
 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in
connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with Section 1110, the Company will comply with the applicable securities laws and
regulations and will not be deemed to have breached its obligations under Section 1110 by virtue of such compliance. 
 On
the Change of Control Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Notes
or portions of Notes properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying
Agent an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and 
 (3) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being
purchased by the Company. 
 The Paying Agent will promptly mail or wire transfer to each Holder of Notes properly tendered the
Change of Control Payment for such Notes (or, if all the Notes are then in global form, make such payment through the facilities of the Depositary), and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to
each Holder a new Note equal in principal amount to any unpurchased portion of the Notes 

  
 63 

 
surrendered, if any; provided that each such new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess of $2,000. Any Note so accepted for payment will
cease to accrue interest on and after the Change of Control Payment Date unless the Company defaults in making the Change of Control Payment. 
 The Company will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. 

Notwithstanding anything to the contrary in this Section 1110, the Company will not be required to make a Change of Control Offer
upon a Change of Control if (1) a third party makes the Change of Control Offer in the manner, at the price, at the times and otherwise in compliance with the requirements set forth in this Section 1110 applicable to a Change of Control
Offer made by the Company and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer or (2) notice of redemption has been given pursuant to paragraph 5 of the Notes unless and until there is a default in
payment of the applicable redemption price. 
 A Change of Control Offer may be made in advance of a Change of Control, and
conditioned upon the occurrence of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer. Notes repurchased by the Company pursuant to a Change of Control Offer will
have the status of Notes issued but not Outstanding or will be retired and cancelled, at the Company’s option. Notes purchased by a third party pursuant to the sixth paragraph of this Section 1110 will have the status of Notes issued and
Outstanding. 
 In the event that Holders of at least 90% of the aggregate principal amount of the Outstanding Notes accept a
Change of Control Offer and the Company (or any third party making such Change of Control Offer, in lieu of the Company, as described in the sixth paragraph of this Section 1110) purchases all of the Notes held by such Holders, the Company will
have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following a Change of Control Payment Date, to redeem all, but not less than all, of the Notes that remain Outstanding at a Redemption Price
equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain Outstanding, to the Redemption Date (subject to the right of Holders on the
relevant record date to receive interest due on the relevant Interest Payment Date). 
 Section 1111. Incurrence of Indebtedness and
Issuance of Preferred Stock. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or
indirectly create, incur, issue, assume, Guarantee or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”; with “incurrence” having a correlative
meaning) any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Stock and will not permit any of its Restricted Subsidiaries to issue any preferred stock; provided, however, that the Company may
incur Indebtedness (including Acquired Debt) and issue Disqualified Stock, and Subsidiary Guarantors may incur Indebtedness (including Acquired Debt) and issue preferred stock, if (i) the Fixed Charge Coverage Ratio for the Company’s most
recently ended four full fiscal quarters for which internal financial statements are available immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Stock or preferred stock is issued, as the case may
be, would have been at least 2.25 to 1.0, determined on a pro forma basis (including a pro forma application of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Stock or preferred
stock had been issued, as the case may be, at the beginning of such four-quarter period and (ii) no Default would occur as a consequence of, and no Event of Default would be continuing following, the incurrence of the Indebtedness or the
transactions relating to such incurrence, including any related application of the proceeds thereof. 
 Notwithstanding the
foregoing, the preceding paragraph of this Section 1111 will not prohibit the incurrence or issuance of any of the following items of Indebtedness or the issuance of any Disqualified Stock or preferred stock described in clauses (5) and
(7) of this paragraph (collectively, “Permitted Debt”): 
 (1) the incurrence by the
Company and any Restricted Subsidiary of Indebtedness under Credit Facilities in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a principal amount equal to the
maximum potential liability of the Company and its Restricted Subsidiaries thereunder) not to exceed the greater of (a) $500.0 million and (b) the sum of $200.0 million plus an amount equal to 35% of Adjusted Consolidated Net Tangible
Assets of the Company, determined as of the date of the incurrence of such Indebtedness after giving pro forma effect to such incurrence and the application of the proceeds therefrom; 

  
 64 

 (2) the incurrence by the Company or any Restricted Subsidiary of Existing
Indebtedness; 
 (3) the incurrence by the Company of Indebtedness represented by the Notes to be issued on the
Issue Date and by any Subsidiary Guarantor of the Subsidiary Guarantees; 
 (4) the incurrence by the Company or
any Restricted Subsidiary of Indebtedness represented by Capital Lease Obligations, mortgage financings or purchase money obligations, in each case, incurred for the purpose of financing all or any part of the purchase price or cost of design,
construction, installation, improvement, deployment, refurbishment or modification of property, plant or equipment or furniture, fixtures and equipment, in each case, used in the business of the Company or any Restricted Subsidiary, in an aggregate
principal amount at any time outstanding, including all Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness incurred pursuant to this clause (4),
not to exceed the greater of (a) $25.0 million and (b) 2% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness; 

(5) the incurrence or issuance by the Company or any Restricted Subsidiary of Permitted Refinancing Indebtedness in
exchange for, or the net proceeds of which are used to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness (other than intercompany Indebtedness) or Disqualified Stock of the Company, or
Indebtedness (other than intercompany Indebtedness) or preferred stock of any Restricted Subsidiary, in each case that was permitted by the Indenture to be incurred or issued under the first paragraph of this Section 1111 or clause (2), (3),
(4), (10), (14) or (16) of this paragraph or this clause (5); 
 (6) the incurrence by the Company or
any Restricted Subsidiary of intercompany Indebtedness between or among the Company and any Restricted Subsidiary; provided, however, that (a) if the Company or any Subsidiary Guarantor is the obligor on such Indebtedness and the
payee is not the Company or a Subsidiary Guarantor, such Indebtedness must be expressly subordinated to the prior payment in full in cash of all obligations then due with respect to the Notes, in the case of the Company, or the Subsidiary Guarantee,
in the case of a Subsidiary Guarantor; and (b)(i) any subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company or a Restricted Subsidiary and (ii) any sale or other
transfer of any such Indebtedness to a Person that is not either the Company or a Restricted Subsidiary will be deemed, in each case, to constitute an incurrence of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be,
that was not permitted by this clause (6); 
 (7) the issuance by any Restricted Subsidiary to the Company or to
any Restricted Subsidiary of any preferred stock; provided, however, that: 
 (a) any subsequent
issuance or transfer of Equity Interests that results in any such preferred stock being held by a Person other than the Company or a Restricted Subsidiary; and 
 (b) any sale or other transfer of any such preferred stock to a Person that is not either the Company or a Restricted Subsidiary, will be deemed, in each case, to constitute an issuance of such preferred
stock by such Restricted Subsidiary that was not permitted by this clause (7); 
 (8) the incurrence of
obligations of the Company or any Restricted Subsidiary pursuant to Hedging Obligations, in each case entered into for the non-speculative purpose of limiting risks that arise in business of the Company and its Restricted Subsidiaries; 

  
 65 

 (9) the Guarantee by the Company or any Subsidiary Guarantor of Indebtedness
of the Company or a Restricted Subsidiary that was permitted to be incurred by another provision of this Section 1111; provided that if the Indebtedness being Guaranteed is subordinated to or pari passu with the Notes, then the
Guarantee shall be subordinated or pari passu, as applicable, to the same extent as the Indebtedness Guaranteed; 
 (10) the incurrence by the Company or any Restricted Subsidiary of Permitted Acquisition Indebtedness; 
 (11) the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from the honoring by a bank or other financial institution of a check, draft or similar instrument drawn against
insufficient funds, so long as such Indebtedness is covered within five Business Days; 
 (12) the incurrence by
the Company or any Restricted Subsidiary of Indebtedness consisting of the financing of insurance premiums in customary amounts consistent with the operations and business of the Company and its Restricted Subsidiaries; 

(13) the incurrence by the Company or any Restricted Subsidiary of Indebtedness constituting reimbursement obligations
with respect to letters of credit; provided that upon the drawing of such letters of credit, such obligations are reimbursed within 30 days following such drawing; 

(14) the incurrence by the Company or any Restricted Subsidiary of Indebtedness arising from Guarantees of Indebtedness of
joint ventures at any time outstanding not to exceed the greater of (a) $35.0 million and (b) 4% of Adjusted Consolidated Net Tangible Assets of the Company, in each case, determined as of the date of incurrence of such Indebtedness after
giving pro forma effect to such incurrence and the application of proceeds thereof; 
 (15) the incurrence
of Indebtedness arising from agreements of the Company or any Restricted Subsidiary providing for indemnification, adjustment of purchase price, earn-outs or similar obligations, in each case incurred or assumed in connection with the disposition or
acquisition of any business, assets or a Subsidiary in accordance with this Indenture, other than guarantees of Indebtedness incurred or assumed by any Person acquiring all or any portion of such business, assets or Subsidiary for the purpose of
financing such acquisition; and 
 (16) the incurrence by the Company or any Restricted Subsidiary of
Indebtedness in an aggregate principal amount that, when taken together with all other Indebtedness of the Company and its Restricted Subsidiaries outstanding on the date of such incurrence (other than Indebtedness permitted by clauses
(1) through (15) above or the first paragraph of this Section 1111) and any Permitted Refinancing Indebtedness incurred to extend, renew, refund, refinance, replace, defease, discharge or otherwise retire for value any Indebtedness
incurred pursuant to this clause (16) does not exceed the greater of (a) $50.0 million and (b) 5% of Adjusted Consolidated Net Tangible Assets of the Company, determined as of the date of the incurrence of such Indebtedness after
giving pro forma effect to such incurrence and the application of the proceeds therefrom. 
 The Company will not incur,
and will not permit any Subsidiary Guarantor to incur, any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such Subsidiary Guarantor unless such Indebtedness
is also contractually subordinated in right of payment to the Notes and the applicable Subsidiary Guarantee, on substantially identical terms; provided, however, that no Indebtedness will be deemed to be contractually subordinated in
right of payment to any other Indebtedness of the Company solely by virtue of being unsecured or by virtue of being secured on a first or junior Lien basis. 
 For purposes of determining compliance with this Section 1111, (a) in the event that an item of proposed Indebtedness, Disqualified Stock or preferred stock meets the criteria of more than one
of the categories of Permitted Debt described in clauses (1) through (16) of the second paragraph of this Section 1111, or is entitled to be incurred or issued pursuant to the first paragraph of Section 1111, the Company will be
permitted to divide and 

  
 66 

 
classify such item, in whole or in part, on the date of its incurrence or issuance, or later divide and reclassify all or a portion of such item, in any manner that complies with this
Section 1111 and (b) all Indebtedness outstanding on the Issue Date or committed to on or prior to the Issue Date, in each case under the Senior Credit Agreement shall be deemed incurred on the Issue Date under clause (1) of the
second paragraph of this Section 1111. The accrual of interest, the accretion or amortization of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the
reclassification of preferred stock as Indebtedness due to a change in accounting principles, fluctuations in the termination value of Hedging Obligations and the payment of dividends on Disqualified Stock or preferred stock in the form of
additional Disqualified Stock or preferred stock of the same class will be deemed not to be an incurrence of Indebtedness or an issuance of Disqualified Stock or preferred stock for purposes of this Section 1111; provided, in each such
case, that the amount of any such accrual, accretion or payment is included in Fixed Charges of the Company as accrued. The amount of any Indebtedness outstanding as of any date shall be (a) the accreted value thereof in the case of any
Indebtedness issued with original issue discount and (b) the principal amount or liquidation preference thereof, in the case of any other Indebtedness. If obligations in respect of letters of credit are incurred pursuant to a Credit Facility
and are being treated as incurred pursuant to clause (1) of the second paragraph of this Section 1111 and the letters of credit relate to other Indebtedness, then such other Indebtedness shall not be included. 

For purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S.
dollar-equivalent principal amount of Indebtedness denominated in a foreign currency shall be calculated based on the relevant currency exchange rate in effect on the date such Indebtedness was incurred, in the case of term Indebtedness, or first
committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated
restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such
refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. Notwithstanding any other provision of this Section 1111, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may
incur pursuant to this Section 1111 shall not be deemed to be exceeded solely as a result of fluctuations in the exchange rate of currencies. The principal amount of any Permitted Refinancing Indebtedness incurred to refinance other
Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Permitted Refinancing Indebtedness is denominated that is in
effect on the date of such refinancing. 
 Section 1112. Restricted Payments. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly: 

(1) declare or pay any dividend or make any other payment or distribution on account of the Company’s or any

 (9) purchases of Subordinated Debt at a purchase price not greater than (a) 101% of the principal amount
of such Subordinated Debt and accrued and unpaid interest thereon in the event of a Change of Control or (b) 100% of the principal amount of such Subordinated Debt and accrued and unpaid interest thereon in the event of an Asset Sale in
connection with any change of control offer or asset sale offer required by the terms of such Subordinated Debt, but only if:

except the Fair Market Value of any non-cash dividend made within 60 days after the date of declaration shall be determined as of such date. The Fair Market Value of any cash Restricted Payment shall be its face amount, and the Fair Market Value of
any non-cash Restricted Payment shall be determined in accordance with the definition of that term. 
 For purposes of
determining compliance with this Section 1112, if a Restricted Payment meets the criteria of more than one of the types of Restricted Payments described in clauses (1) through (13) above, the Company, in its sole discretion, may order
and classify and subsequently re-order and re-classify, such Restricted Payment in any manner in compliance with this Section 1112. 

  
 70 

 In computing Consolidated Net Income under this Section 1112, (1) the Company
shall use audited financial statements for the portions of the relevant period for which audited financial statements are available on the date of determination and unaudited financial statements and other current financial data based on the books
and records of the Company for the remaining portion of such period and (2) the Company shall be permitted to rely in good faith on the financial statements and other financial data derived from the books and records of the Company that are
available on the date of determination. 
 Section 1113. Limitation on Liens. 

The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur or permit to exist
any Lien (the “Initial Lien”), other than Permitted Liens, upon any of its property or assets (including Capital Stock and Indebtedness of any Subsidiaries of the Company and including any income or profits from such property or
assets), whether owned on the Issue Date or thereafter acquired, which Lien secures any Subordinated Debt or other Indebtedness, unless: 
 (1) in the case of Liens securing Subordinated Debt of the Company or a Subsidiary Guarantor, the Notes or Subsidiary Guarantee, as applicable, are secured by a Lien on such property or assets on a senior
basis to the Subordinated Debt so secured with the same priority as the Notes or such Subsidiary Guarantee, as applicable, has to such Subordinated Debt until such time as such Subordinated Debt is no longer so secured by a Lien; and 

(2) in the case of Liens securing other Indebtedness of the Company or a Subsidiary Guarantor, the Notes or Subsidiary
Guarantees, as applicable, are secured by a Lien on such property or assets on an equal and ratable basis with the other Indebtedness so secured until such time as such other Indebtedness is no longer so secured by a Lien. 

Any Lien securing the Notes or Subsidiary Guarantees created pursuant to the preceding paragraph of this Section 1113 shall provide
by its terms that such Lien shall be automatically and unconditionally released and discharged upon the unconditional release and discharge of the Initial Lien. 
 Section 1114. Dividend and Other Payment Restrictions Affecting Restricted Subsidiaries. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become effective any consensual encumbrance or restriction on the
ability of any Restricted Subsidiary to: 
 (1) pay dividends or make any other distributions on its Capital
Stock to the Company or any Restricted Subsidiary, or pay any Indebtedness owed to the Company or any Restricted Subsidiary; 
 (2) make loans or advances to the Company or any Restricted Subsidiary; or 
 (3) sell, lease or transfer any of its properties or assets to the Company or any Restricted Subsidiary. 
 However, the preceding restrictions in the first paragraph of this Section 1114 will not apply to encumbrances or restrictions existing under, by reason of or with respect to: 

(1) the Senior Credit Agreement, any Existing Indebtedness, Capital Stock or any other agreements or instruments, in each
case, in effect on the Issue Date and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings thereof; provided that the encumbrances and restrictions in any such
amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good faith judgment of the Chief Executive Officer and the Chief Financial Officer of the Company,
not materially more restrictive, taken as a whole, than those contained in the applicable agreements or instruments as in effect on the Issue Date; 

  
 71 

 (2) the Indenture, the Notes and the Subsidiary Guarantees; 

(3) applicable law, rule, regulation, order, approval, permit or similar restriction; 

(4) any instrument governing Indebtedness or Capital Stock of a Person acquired by the Company or any Restricted
Subsidiary as in effect at the time of such acquisition (except to the extent such Indebtedness or Capital Stock was incurred in connection with or in contemplation of such acquisition), which encumbrance or restriction is not applicable to any
Person, or the properties or assets of any Person, other than the Person, or the property or assets of the Person, so acquired and any amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or
refinancings thereof; provided, that the encumbrances and restrictions in any such amendments, restatements, modifications, renewals, extensions, supplements, increases, refundings, replacements or refinancings are, in the reasonable good
faith judgment of the Chief Executive Officer and the Chief Financial Officer of the Company, not materially more restrictive, taken as a whole, than those in effect on the date of the acquisition; provided, further, that, in the case
of Indebtedness, such Indebtedness was permitted by the terms of the Indenture to be incurred; 
 (5) customary
non-assignment provisions in contracts, leases, licenses and sublicenses (including, without limitation, licenses of intellectual property) and provisions restricting subletting or assignment of any lease governing a leasehold interest (including
leases governing leasehold interests or Farm-In Agreements or Farm-Out Agreements) relating to leasehold interests in oil and gas properties) of the Company or any Restricted Subsidiary; 

(6) any agreement for the sale or other disposition of the Equity Interests in, or all or substantially all of the
properties or assets of, a Restricted Subsidiary, that restricts distributions by the applicable Restricted Subsidiary pending the sale or other disposition; 
 (7) Permitted Refinancing Indebtedness; provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not in the reasonable good faith judgment of
the Chief Executive Officer and Chief Financial Officer of the Company, materially more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced; 

(8) Liens permitted to be incurred under the provisions of Section 1113 that limit the right of the debtor to dispose
of the assets subject to such Liens and the security documents relating thereto; 
 (9) the issuance of preferred
stock by a Restricted Subsidiary or the payment of dividends thereon in accordance with the terms thereof; provided that issuance of such preferred stock is permitted pursuant to Section 1111 and the terms of such preferred stock do not
expressly restrict the ability of a Restricted Subsidiary to pay dividends or make any other distributions on its Capital Stock (other than requirements to pay dividends or liquidation preferences on such preferred stock prior to paying any
dividends or making any other distributions on such other Capital Stock); 
 (10) other Indebtedness of the
Company or any Restricted Subsidiary permitted to be incurred pursuant to an agreement entered into subsequent to the Issue Date in accordance with Section 1111; provided that the provisions relating to such encumbrance or restriction
contained in such Indebtedness are not materially less favorable to the Company and its Restricted Subsidiaries, taken as a whole, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial Officer of the Company, than
the provisions contained in the Senior Credit Agreement or any other agreement described in clause (1) above as in effect on the Issue Date; 

  
 72 

 (11) Indebtedness incurred or Capital Stock issued by any Restricted
Subsidiary, provided that the restrictions contained in the agreements or instruments governing such Indebtedness or Capital Stock (a) apply only in the event of a payment default or a default with respect to a financial covenant in such
agreement or instrument or (b) will not materially affect the Company’s ability to pay all principal, interest and premium, if any, on the Notes, in the reasonable good faith judgment of the Chief Executive Officer and Chief Financial
Officer of the Company;

and gas business and other similar agreements entered into (i) in the ordinary course of business, or (ii) with the approval of the Company’s Board of Directors, which limitations are applicable only to the assets, property or Capital
Stock that are the subject of such agreements;

Subsidiary that is designated a Restricted Subsidiary, in each case that is in existence at the time of such designation (but not created in contemplation of or in connection thereof); and 

(17) Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments to the
extent such encumbrance or restriction restricts the transfer of the property (including Capital Stock) subject to such Capital Lease Obligations, security agreements, mortgages, purchase money agreements or similar instruments. 

Section 1115. Asset Sales. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, consummate an Asset Sale unless: 
 (1) the Company (or the Restricted Subsidiary, as the case may be) receives consideration at the time of such Asset Sale at least equal to the Fair Market Value of the assets or Equity Interests issued or
sold or otherwise disposed of; and 
 (2) at least 75% of the aggregate consideration received in respect of such
Asset Sale and all other Asset Sales since the Issue Date by the Company and its Restricted Subsidiaries is in the form of cash or Cash Equivalents; provided that, for purposes of this provision, each of the following will be deemed to be
cash: 
 (a) any liabilities, as shown on the Company’s most recent consolidated balance sheet, of the
Company or any Restricted Subsidiary (other than contingent liabilities, Subordinated Debt and any obligations in respect of preferred stock) that are assumed by the transferee of any such assets or Equity Interests pursuant to novation agreements
(or other legal documentation with the same effect) that includes a full release of the Company or such Restricted Subsidiary from any and all liability therefor; 

  
 73 

 (b) any securities, notes or other obligations received by the Company or
any such Restricted Subsidiary from such transferee that are converted by the Company or such Restricted Subsidiary into cash within 180 days after the date of the Asset Sale, to the extent of the cash received in that conversion; and

 (c) Additional Assets. 
 Notwithstanding the foregoing, the 75% limitation referred to in clause (2) of the first paragraph of this Section 1115 shall be deemed satisfied with respect to any Asset Sale in which the cash
or Cash Equivalents portion of the consideration received therefrom, determined in accordance with clause (2) of the first paragraph of this Section 1115 on an after-tax basis, is equal to or greater than what the after-tax proceeds would
have been had such Asset Sale complied with the aforementioned 75% limitation. 
 Within 365 days after the receipt of any
Net Proceeds from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds, at its option: 
 (1) to repay, prepay, redeem or purchase (x) Indebtedness and other Obligations under a Credit Facility; provided that, in the case of any such action with respect to a revolving Credit
Facility shall be accompanied by a reduction of the related commitments or facility amount, (y) any Indebtedness and other Obligations that were secured by the assets sold in such Asset Sale or (z) other pari passu Indebtedness and
Obligations with respect thereto; provided, that in the case of this clause (z), the Company shall also equally and ratably reduce Indebtedness under the notes by making an offer (in accordance with the procedures set forth below for an Asset
Sale) to all holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, the pro rata principal amount of Notes; 

(2) to invest in Additional Assets; or 

(3) to make capital expenditures in respect of a Related Business of the Company or Restricted Subsidiary. 

provided that the Company and its Restricted Subsidiaries will be deemed to have complied with this paragraph if and to the extent that, within
365 days after the Asset Sale that generated the Net Proceeds, the Company or such Restricted Subsidiary has entered into and not abandoned or rejected a binding agreement to consummate any such investment described in this paragraph with the good
faith expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days after the end of such 365-day period; provided, further, that if such commitment is later canceled or terminated before such Net
Proceeds are applied or otherwise not applied within such 180 day period, then such Net Proceeds shall constitute “Excess Proceeds.” 
 However, pending application or investment of such Net Proceeds as provided in clauses (1) through (3) of the immediately preceding paragraph, such Net Proceeds may be applied to temporarily
reduce revolving credit Indebtedness. An amount equal to any Net Proceeds from Asset Sales that are not applied or invested as provided in clauses (1) through (3) above will constitute “Excess Proceeds.” 

Within ten Business Days after the aggregate amount of Excess Proceeds exceeds $20.0 million, the Company will make an offer (an
“Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 1115 with respect to offers to purchase
or redeem with the proceeds of sales of assets, to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds. The offer price for the Notes in any Asset Sale Offer
will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds remain after consummation of an Asset Sale Offer, the Company or any Restricted
Subsidiary may use those Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess
Proceeds, the Company will use the Excess Proceeds to purchase the Notes and such other pari passu Indebtedness on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Proceeds will be reset at zero.

  
 74 

 Notwithstanding the foregoing, the sale, conveyance or other disposition of all or
substantially all of the properties or assets of the Company and its Restricted Subsidiaries, taken as a whole, will be governed by Sections 901 and/or 1110 of this Supplemental Indenture, as applicable, and not by this Section 1115.

 The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and
regulations thereunder to the extent those laws and regulations are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this
Section 1115, or compliance with this Section 1115 would constitute a violation of any such laws or regulations, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its
obligations under this Section 1115 by virtue of such compliance. 
 In the event that, pursuant to this Section 1115,
the Company is required to commence an Asset Sale Offer, it will follow the procedures specified below: 
 (1)
The Asset Sale Offer shall be made to all Holders and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this Section 1115. The Asset Sale Offer will remain open for a
period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than three Business Days after
the termination of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”) to the purchase of Notes and such other pari passu Indebtedness (on a pro rata
basis, if applicable) or, if less than the Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so purchased will be made in the same manner as interest payments are
made. 
 (2) If the Purchase Date is on or after an interest record date and on or before the related Interest
Payment Date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Asset
Sale Offer. 
 (3) Upon the commencement of an Asset Sale Offer, the Company will send a notice to the Trustee
and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

 (a) that the Asset Sale Offer is being made pursuant to this Section 1115 and the length of time the
Asset Sale Offer will remain open; 
 (b) the Offer Amount, the purchase price and the Purchase Date; 

(c) that any Note not tendered or accepted for payment will continue to accrue interest; 

(d) that, unless the Company defaults in making such payment, any Note accepted for payment pursuant to the Asset Sale
Offer will cease to accrue interest after the Purchase Date; 
 (e) that Holders electing to have a Note
purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000 only; 

(f) that Holders electing to have Notes purchased pursuant to any Asset Sale Offer will be required to surrender the
Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer by bookentry transfer, to the Company, a depositary, if appointed by the Company, or a Paying Agent at the address specified in
the notice prior to the close of business on the third Business Day preceding the Purchase Date; 

  
 75 

 (g) that Holders will be entitled to withdraw their election if the Company,
the depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Offer Period, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note the
Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Note purchased; 
 (h) that, if the aggregate principal amount of Notes and other pari passu Indebtedness surrendered by Holders thereof exceeds the Offer Amount, the Company will select the Notes and other pari
passu Indebtedness to be purchased on a pro rata basis based on the principal amount of Notes and such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only Notes
in denominations of $2,000, or an integral multiple of $1,000 in excess of $2,000, will be purchased); and 
 (i)
that Holders whose Notes were purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer), which unpurchased portion must be equal to $2,000 in
principal amount or an integral multiple of $1,000 in excess of $2,000. 
 (4) On or before the Purchase Date,
the Company will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been
tendered, all Notes tendered, and will deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating that such Notes or portions thereof were accepted for payment by the Company in
accordance with the terms of this Section 1115. The Company, the depositary or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after the Purchase Date) mail or deliver to each tendering Holder an
amount equal to the purchase price of the Notes tendered by such Holder and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the Company, will authenticate and mail or
deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the Company to the
Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date. 
 Section 1116.
Transactions with Affiliates. 
 The Company will not, and will not permit any of its Restricted Subsidiaries to, make
any payment to, or sell, lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction, contract, agreement, understanding, loan, advance or
Guarantee with, or for the benefit of, any Affiliate of the Company (each, an “Affiliate Transaction”) involving aggregate consideration to or from the Company or a Restricted Subsidiary in excess of $1.0 million, unless:

 (1) the Affiliate Transaction is on terms that are no less favorable to the Company or the relevant Restricted
Subsidiary than those that would have been obtained in a comparable transaction by the Company or such Restricted Subsidiary with a Person that is not an Affiliate of the Company; and 

(2) the Company delivers to the Trustee: 

(a) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration to or from the Company or a Restricted Subsidiary, in excess of $15.0 million an Officers’ Certificate certifying that such Affiliate Transaction or series of related Affiliate Transactions complies with this Section 1116;
and 

  
 76 

 (b) with respect to any Affiliate Transaction or series of related Affiliate
Transactions involving aggregate consideration to or from the Company or a Restricted Subsidiary, in excess of $30.0 million, a majority of the Disinterested Members of the Board of Directors (or, if there is only one Disinterested Member, such
Disinterested Member) have determined that the criteria set forth in clause (1) above are satisfied with respect to such Affiliate Transaction(s) and have approved such Affiliate Transaction(s), as evidenced by a Board Resolution delivered to
the Trustee and certified by an Officers’ Certificate as having been adopted by such Disinterested Member on behalf of the Board of Directors. 
 The following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of the prior paragraph of this Section 1116: 

(1) any employment, consulting, severance, termination or similar agreement or arrangement, stock option or stock
ownership plan, employee benefit plan, officer or director compensation or indemnification agreement, restricted stock agreement, severance agreement or other compensation plan or arrangement entered into by the Company or any Restricted Subsidiary
in the ordinary course of business and payments, awards, grants or issuances of securities pursuant thereto; 

(2) transactions between or among the Company and/or its Restricted Subsidiaries and the issuance of Guarantees for the
benefit of the Company or a Restricted Subsidiary; 
 (3) transactions with a Person (other than an Unrestricted
Subsidiary) that is an Affiliate of the Company solely because the Company owns, directly or through a Subsidiary, an Equity Interest in, or controls, such Person; 

(4) fees and expenses and compensation paid to, and indemnification or insurance provided on behalf of, officers,
directors or employees of the Company or any Restricted Subsidiary; 
 (5) any issuance of Equity Interests
(other than Disqualified Stock) of the Company to, or receipt of a capital contribution from, Affiliates of the Company; 
 (6) Restricted Payments that do not violate Section 1112 and any Permitted Investments; 
 (7) loans or advances to employees in the ordinary course of business or consistent with past practice; 
 (8) advances to or reimbursements of employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures in the ordinary course of business; 

(9) the performance of obligations of the Company or any Restricted Subsidiary under the terms of any written agreement to
which the Company or any Restricted Subsidiary was a party on the Issue Date, as these agreements may be amended, modified or supplemented from time to time; provided, however, that any future amendment, modification or supplement
entered into after the Issue Date will be permitted to the extent that its terms do not materially and adversely affect the rights of any Holders of the Notes (as determined in good faith by the Board of Directors of the Company) as compared to the
terms of the agreements in effect on the Issue Date; 
 (10) (a) guarantees of performance by the Company and its
Restricted Subsidiaries of Unrestricted Subsidiaries in the ordinary course of business, except for Guarantees of Indebtedness in respect of borrowed money, and (b) pledges of Equity Interests of Unrestricted Subsidiaries for the benefit of
lenders of Unrestricted Subsidiaries; 
 (11) transactions between the Company or any Restricted Subsidiary and
any Person, a director of which is also a director of the Company or any direct or indirect parent company of the Company and such director is the sole cause for such Person to be deemed an Affiliate of the Company or any Restricted Subsidiary;
provided, however, that such director abstains from voting as director of the Company or such direct or indirect parent company of the Company, as the case may be, on any matter involving such other Person; 

  
 77 

 (12) (i) contracts for (A) drilling or other oil-field services or
supplies, (B) the sale, storage, gathering or transport of hydrocarbons or (C) the lease or rental of office or storage space or (ii) transactions with customers, clients, suppliers, or purchasers or sellers of assets or services, in
each case entered into in the ordinary course of business and otherwise in compliance with the terms of the Indenture, provided that in the reasonable determination of the Board of Directors of the Company or the senior management of the
Company, such transactions are on terms not materially less favorable to the Company or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length
basis from a Person that is not an Affiliate of the Company; and 
 (13) any transaction with a joint venture or
similar entity that would constitute an Affiliate Transaction solely because the Company or a Restricted Subsidiary owns, directly or indirectly, an Equity Interest in or otherwise controls such joint venture or similar entity. 

Section 1117. Future Subsidiary Guarantees. 
 The Company will cause each Restricted Subsidiary that (x) Guarantees any Indebtedness or becomes an obligor under a Credit Facility, in either case in excess of a De Minimis Amount (other than a
Foreign Subsidiary created or acquired by the Company or one or more of its Restricted Subsidiaries), or (y) issues any preferred stock to become a Subsidiary Guarantor by executing and delivering a supplemental indenture, substantially in the
form provided for in Annex C of this Supplemental Indenture, to the Trustee within 30 days of the date on which it incurred such Indebtedness or issued such preferred stock (in each case, referred to in clause (1) or (2) of this sentence).
Such supplemental indenture shall be accompanied by an Opinion of Counsel to the Trustee to the effect that such supplemental indenture has been duly authorized, executed and delivered by that Restricted Subsidiary and constitutes a valid and
binding agreement of such Subsidiary, enforceable in accordance with its terms (subject to customary exceptions). 
 Each
Subsidiary Guarantee shall be released in accordance with Section 1604. 
 Section 1118. Designation of Restricted and Unrestricted
Subsidiaries. 
 The Board of Directors of the Company may designate any Restricted Subsidiary to be an Unrestricted
Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its Restricted Subsidiaries in
the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time of the designation. That designation will only be permitted if the applicable Restricted Subsidiary meets the definition of an
Unrestricted Subsidiary and if such Investment would be permitted at that time, either pursuant to (1) Section 1112 or (2) the definition of Permitted Investment. 

Any designation of a Subsidiary of the Company as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee
a certified copy of a Board Resolution of the Company giving effect to such designation and an Officers’ Certificate certifying that such designation complied with the preceding conditions and was permitted by Section 1112. If, at any
time, any Unrestricted Subsidiary would fail to meet the requirements of the definition of “Unrestricted Subsidiary” set forth in Section 201 of this Supplemental Indenture, it will thereafter cease to be an Unrestricted Subsidiary
for purposes of the Indenture and any Indebtedness of such Subsidiary will be deemed to be incurred by a Restricted Subsidiary as of such date and, if such Indebtedness is not permitted to be incurred as of such date under Section 1111, the
Company will be in Default of the covenant in Section 1111. 
 The Board of Directors of the Company may at any time
designate any Unrestricted Subsidiary to be a Restricted Subsidiary; provided that such designation will be deemed to be an incurrence of Indebtedness by a Restricted Subsidiary of any outstanding Indebtedness of such Unrestricted Subsidiary,
and such designation will only be permitted if (1) such Indebtedness is permitted under Section 1111, calculated on a pro forma basis as if such designation had occurred at the beginning of the four-quarter reference period; and
(2) no Default or Event of Default would be in existence following such designation. 

  
 78 

 Section 1119. Termination of Certain Covenants. 

From and after the time when (i) the Notes have Investment Grade Ratings from both Rating Agencies and (ii) no Default or Event
of Default has occurred and is continuing under the Indenture (the occurrence of the events described in the foregoing clauses (i) and (ii) being collectively referred to as a “Covenant Termination Event”), the Company and
its Restricted Subsidiaries shall not be subject to clause (4) of Section 901 and Sections 1111, 1112, 1114, 1115 and 1116 of this Supplemental Indenture. Upon the occurrence of a Covenant Termination Event, the amount of Excess Proceeds
from Net Proceeds shall be set to zero under the Indenture. 
 ARTICLE TWELVE 

REDEMPTION OF NOTES 

Section 1201. Applicability of Article. 
 The Notes shall be redeemable at the election of the Company in accordance with their terms and in accordance with this Article Twelve. 
 Section 1202. Election to Redeem; Notice to Trustee. 
 In case of any
redemption of less than all Notes, the Company shall, at least five Business Days prior to the giving of notice of such redemption (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of the Redemption Date
and of the principal amount of Notes to be redeemed. In the case of any redemption of Notes (1) prior to the expiration of any restriction on such redemption provided in the terms of the Notes or elsewhere in the Indenture or (2) pursuant
to an election of the Company that is subject to a condition specified in the terms of the Notes or elsewhere in the Indenture, the Company shall furnish the Trustee, prior to giving notice of such redemption, with an Officers’ Certificate
evidencing compliance with such restriction or condition. 
 Section 1203. Optional Redemption. 

At its option, the Company may redeem the Notes, in whole or in part, in principal amounts of $2,000 or any integral multiple of $1,000
in excess thereof, at any time or from time to time, at the applicable Redemption Prices determined as set forth in the form of Note attached as Annex A hereto, in accordance with the terms set forth in the Notes, and in accordance with this Article
Twelve. 
 Section 1204. Selection by Trustee of Notes to Be Redeemed. 

If less than all of the Notes are to be redeemed at any time, the Trustee will select the Notes to be redeemed among the Holders of the
Notes on a pro rata basis (or, in the case of Global Notes, the Trustee will select the Notes for redemption based on DTC’s method that most nearly approximates a pro rata selection), unless otherwise required by law or applicable
securities exchange requirements. 
 The Trustee shall promptly notify the Company in writing of the Notes selected for
redemption and, in the case of any Note selected for partial redemption, the principal amount at maturity thereof to be redeemed. No Notes in amounts of $2,000 or less shall be redeemed in part. Notes and portions of Notes selected shall be in
amounts of $2,000 and integral multiples of $1,000 in excess thereof; except that if all of the Notes of a Holder are to be redeemed, the entire Outstanding amount of Notes held by such Holder, even if less than $2,000 and/or a non-multiple of
$1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of the Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption. 

  
 79 

 Section 1205. Notice of Redemption. 

Subject to the final paragraph of this Section 1205, at least 30 days but not more than 60 days before a Redemption Date, the
Company shall send a notice of redemption to each Holder whose Notes are to be redeemed at its registered address; provided, however, that (notwithstanding the foregoing) notices of redemption may be sent more than 60 days prior to a
Redemption Date if such notice is issued in connection with a Defeasance or Covenant Defeasance of the Notes or the satisfaction and discharge of this Indenture. 
 The notice shall identify the Notes to be redeemed and shall state: 

(1) the Redemption Date; 
 (2) the Redemption Price, or if not then ascertainable, the manner of calculation thereof; 
 (3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date upon surrender of such Note, a new Note or Notes in principal
amount equal to the unredeemed portion of the original Note shall be issued in the name of the Holder thereof upon cancellation of the original Note; 
 (4) the name and address of the Paying Agent; 
 (5) that Notes
called for redemption must be surrendered to the Paying Agent to collect the Redemption Price and become due on the date fixed for redemption, unless the redemption is subject to a condition precedent that is not satisfied or waived; 

(6) that, unless the Company defaults in making such redemption payment, interest, if any, on Notes called for redemption
ceases to accrue on and after the Redemption Date; 
 (7) the paragraph of the Notes and/or Section of this
Supplemental Indenture pursuant to which the Notes called for redemption are being redeemed; 
 (8) that no
representation is made as to the correctness or accuracy of the CUSIP or CINS number, if any, listed in such notice or printed on the Notes; and 
 (9) any conditions that must be satisfied prior to the Company becoming obligated to consummate such redemption. 
 At the Company’s request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense; provided, however, that the Company shall have
delivered to the Trustee, at least five Business Days prior to sending of notice of the redemption (or such shorter period of time as may be acceptable to the Trustee), a Company Request that the Trustee give such notice and setting forth the
information to be stated in such notice as provided in the preceding paragraph. 
 Notwithstanding the preceding provisions of
this Section 1205, notice of any redemption with the net cash proceeds of one or more Equity Offerings may be given prior to the completion of the related Equity Offering, and any such redemption or notice may at the Company’s discretion,
be subject to one or more conditions precedent, including, but not limited to completion of the related Equity Offering. 
 Section 1206.
Deposit of Redemption Price. 
 Prior to 11:00 a.m., New York City time, on 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 1103) 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 Notes which are to be redeemed on that date. 

  
 80 

 Section 1207. Notes Payable on Redemption Date. 

Notice of redemption having been given as aforesaid, the Notes 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 or unless a condition specified in the notice of redemption is not satisfied) such
Notes shall cease to bear interest. Upon surrender of any such Notes for redemption in accordance with said notice, such Notes shall be paid by the Company at the Redemption Price, together with accrued interest to the Redemption Date;
provided, however, that installments of interest whose Stated Maturity is on or prior to the Redemption Date will be payable to the Holders of such Notes, or one or more Predecessor Notes, registered as such at the close of business on
the relevant record dates according to their terms and the provisions of Section 407. 
 If any Note called for redemption
shall not be so paid upon surrender thereof for redemption, the principal and any premium shall, until paid, bear interest from the Redemption Date at the rate prescribed therefor in the Note. 

Section 1208. Notes Redeemed in Part. 
 Any Note 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 its attorney duly authorized in writing), and the Company shall execute and the Trustee shall authenticate and deliver to the Holder of such Note without
service charge, a new Note or Notes of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered.

 ARTICLE FOURTEEN 

DEFEASANCE AND COVENANT DEFEASANCE 
 Section 1401. Company’s Option to Effect Defeasance or Covenant Defeasance. 
 The Company may elect, at its option at any time, to have Section 1402 or Section 1403 applied to the Notes, upon compliance with the conditions set forth below in this Article. Any such
election shall be evidenced in a Board Resolution set forth in an Officers’ Certificate delivered to the Trustee. 
 Section 1402.
Defeasance and Discharge. 
 Upon the Company’s exercise of its option to have this Section applied to the Notes,
the Company shall be deemed to have been discharged from its obligations with respect to such Notes as provided in this Section on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter called
“Defeasance”). For this purpose, such Defeasance means that the Company shall be deemed to have paid and discharged the entire indebtedness represented by such Notes and to have satisfied all its other obligations under such Notes
and the Indenture insofar as the Notes are concerned (and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging the same), subject to the following, which shall survive until otherwise terminated or discharged
hereunder: (1) the rights of Holders of such Notes to receive, solely from the trust fund described in Section 1404 and as more fully set forth in such Section, payments in respect of the principal of and any premium and interest on such
Notes when payments are due; (2) the Company’s obligations with respect to such Notes under Sections 404, 405, 406, 1102 and 1103 and its obligations under Section 314(a) of the Trust Indenture Act; (3) the rights, powers,
trusts, duties and immunities of the Trustee hereunder and the Company’s and the Subsidiary Guarantors’ obligations in connection therewith; and (4) this Article. If the Company exercises its defeasance option pursuant to this
Section 1402, the Subsidiary Guarantees will terminate with respect to the Notes, and payment of the Notes may not be accelerated pursuant to Section 602 because of an Event of Default. Subject to compliance with this Article, the Company
may exercise its option to have this Section applied to any Notes notwithstanding the prior exercise of its option to have Section 1403 applied to such Notes. 

  
 81 

 Section 1403. Covenant Defeasance. 

Upon the Company’s exercise of its option to have this Section applied to the Notes, (1) the Company shall be released from its
obligations under Section 901(4), Section 1106, Sections 1110 through 1118, inclusive; (2) the occurrence of any event specified in Sections 601(3) (with respect only to the obligation under Section 901(4)), 601(4), 601(5),
601(6), 601(7), 601(9) (with respect only to Significant Subsidiaries) or 601(10) (with respect only to Subsidiaries), shall be deemed not to be or to result in an Event of Default and (3) the Subsidiary Guarantees shall be automatically
released, in each case with respect to such Notes as provided in this Section on and after the date the conditions set forth in Section 1404 are satisfied (hereinafter called “Covenant Defeasance”). For this purpose, such
Covenant Defeasance means that, with respect to such Notes, the Company may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such specified Section, whether directly or indirectly by
reason of any reference elsewhere herein to any such Section or Article or by reason of any reference in any such Section or Article to any other provision herein or in any other document, but the remainder of the Indenture and such Notes shall be
unaffected thereby. 
 Section 1404. Conditions to Defeasance or Covenant Defeasance. 

The following shall be the conditions to the application of Section 1402 or Section 1403 to any Notes: 

(1) the Company must irrevocably deposit with the Trustee (or another trustee that satisfies the requirements of and
agrees to comply with the provisions of this Article Fourteen applicable to it), in trust, for the benefit of the Holders, cash in U.S. dollars, non-callable Government Securities, or a combination of cash in U.S. dollars and non-callable Government
Securities, in such amounts as will be sufficient, in the opinion of a nationally recognized investment bank, nationally recognized appraisal firm, or nationally recognized firm of independent public accountants to pay the principal of, or interest
and premium, if any, on the Outstanding Notes 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 Notes are being defeased to such stated date for payment or to a
particular Redemption Date; 
 (2) in the case of an election under Section 1402 hereof, the Company must
deliver to the Trustee an Opinion of Counsel confirming that: 
 (a) the Company has received from, or there has
been published by, the Internal Revenue Service a ruling; or 
 (b) since the Issue Date, there has been a change
in the applicable U.S. federal income tax law, 
 in either case to the effect that, and based thereon such Opinion of Counsel
will confirm that, the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Defeasance had not occurred; 
 (3) in the case of an election under
Section 1403 hereof, the Company must deliver to the Trustee an Opinion of Counsel confirming that the Holders will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be
subject to U.S. 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; 

(4) no Default or Event of Default has occurred and is 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 or the grant of Liens securing such borrowing); 
 (5) such Defeasance or Covenant Defeasance and the related deposit will 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; 

  
 82 

 (6) the Company must deliver to the Trustee an Officers’ Certificate
stating that the deposit was not made by the Company with the intent of preferring the Holders over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding any creditors of the Company or others;

 (7) the Company must deliver to the Trustee an Officers’ Certificate, stating that all conditions
precedent set forth in clauses (1) through (6) of this Section 1404 have been complied with; and 

(8) the Company must deliver to the Trustee an Opinion of Counsel, stating that all conditions precedent set forth in
clause (5) of this Section 1404 has been complied with. 
 Section 1405. Deposited Money and Government Securities to Be Held
in Trust; Miscellaneous Provisions. 
 Subject to the provisions of the last paragraph of Section 1103, all money and
Government Securities (including the proceeds thereof) deposited with the Trustee or other qualifying trustee (solely for purposes of this Section and Section 1406, the Trustee and any such other trustee are referred to collectively as the
“Trustee”) pursuant to Section 1404 in respect of any Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and the Indenture, to the payment, either directly or through any
such Paying Agent (including the Company acting as its own Paying Agent) as the Trustee may determine, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal and any premium and interest, but money so held in
trust need not be segregated from other funds except to the extent required by law. 
 The Company shall pay and indemnify the
Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1404 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 Outstanding Notes. 
 Anything in this Article to the contrary
notwithstanding, the Trustee shall deliver or pay to the Company from time to time upon Company Request any money or Government Securities held by it as provided in Section 1404 with respect to any Notes which, in the opinion of a nationally
recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 1404(1)), are in excess of the amount thereof which would then be required
to be deposited to effect the Defeasance or Covenant Defeasance, as the case may be, with respect to such Notes. 
 Section 1406.
Reinstatement. 
 If the Trustee or any Paying Agent is unable to apply any money in accordance with this Article with
respect to any Notes by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations under the Indenture and such Notes from which the Company has been
discharged or released pursuant to Section 1402 or 1403 shall be revived and reinstated as though no deposit had occurred pursuant to this Article with respect to such Notes, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to Section 1405 with respect to such Notes in accordance with this Article; provided, however, that if the Company makes any payment of principal of or any premium or interest on any such Note
following such reinstatement of its obligations, the Company shall be subrogated to the rights (if any) of the Holders of such Notes to receive such payment from the money so held in trust.

 ARTICLE SIXTEEN 

SUBSIDIARY GUARANTEES 

Section 1601. Unconditional Guarantee. 
 For value received, each of the Subsidiary Guarantors hereby fully and unconditionally guarantees (the “Subsidiary Guarantee”) to the Holders and to the Trustee the due and punctual
payment of the principal of, and premium, if any, and interest on the Notes and all other amounts due and payable under the Indenture and the Notes by the Company (collectively, the “Obligations”), when and as such principal,
premium, if any, and interest shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the Notes and the Indenture, subject to the limitations set
forth in Section 1603. 
 Failing payment when due of any amount guaranteed pursuant to its Subsidiary Guarantee, for
whatever reason, each of the Subsidiary Guarantors will be jointly and severally obligated to pay the same immediately. Each Subsidiary Guarantee hereunder is intended to be a general, unsecured, senior obligation of each of the Subsidiary
Guarantors and will rank pari passu in right of payment with all debt of such Subsidiary Guarantor that is not, by its terms, expressly subordinated in right of payment to the Subsidiary Guarantee. Each of the Subsidiary Guarantors hereby
agrees that its obligations hereunder shall be full, unconditional and absolute, irrespective of the validity, regularity or enforceability of the Notes, the Subsidiary Guarantee of any other Subsidiary Guarantor or the Indenture, the absence of any
action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Company or any other Subsidiary Guarantor, or any action to enforce the same or
any other circumstances which might otherwise constitute a legal or equitable discharge or defense of the Subsidiary Guarantors. Each of the Subsidiary Guarantors hereby agrees that in the event of a default in payment of the principal of, or
premium, if any, or interest on the Notes, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to
Section 607, by the Holders, on the terms and conditions set forth in the Indenture, directly against such Subsidiary Guarantor to enforce its Subsidiary Guarantee without first proceeding against the Company or any other Subsidiary Guarantor.

 The obligations of each of the Subsidiary Guarantors under this Article shall be as aforesaid full and unconditional and
shall not be impaired, modified, released or limited by any occurrence or condition whatsoever, including, without limitation, (1) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in,
any of the obligations and liabilities of the Company or any of the other Subsidiary Guarantors contained in the Notes or the Indenture, (2) any impairment, modification, release or limitation of the liability of the Company, any of the other
Subsidiary Guarantors or any of their estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable bankruptcy law, or other statute or from the decision of any
court, (3) the assertion or exercise by the Company, any of the other Subsidiary Guarantors or the Trustee of any rights or remedies under the Notes or the Indenture or their delay in or failure to assert or exercise any such rights or
remedies, (4) the assignment or the purported assignment of any property as security for the Notes, including all or any part of the rights of the Company or any of the other Subsidiary Guarantors under the Indenture, (5) the extension of
the time for payment by the Company or any of the other Subsidiary Guarantors of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of the Notes or the Indenture or of the time for performance by
the Company or any of the other Subsidiary Guarantors of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (6) the modification or amendment (whether material or
otherwise) of any duty, agreement or obligation of the Company or any of the other Subsidiary Guarantors set forth in the Indenture, (7) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially
all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of or other similar proceeding affecting, the Company or
any of the other Subsidiary Guarantors or any of their respective assets, or the disaffirmance of the Notes, the Subsidiary Guarantee or the Indenture in any such proceeding, (8) the release or discharge of the Company or any of the other
Subsidiary Guarantors from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (9) the unenforceability of the Notes or the Indenture or (10) any other
circumstances (other than payment in full or discharge of all amounts guaranteed pursuant to the Subsidiary Guarantees) which might otherwise constitute a legal or equitable discharge of a surety or guarantor. 

  
 84 

 Each of the Subsidiary Guarantors hereby (1) waives diligence, presentment, demand of
payment, filing of claims with a court in the event of the merger, insolvency or bankruptcy of the Company or any of the Subsidiary Guarantors, and all demands whatsoever, (2) acknowledges that any agreement, instrument or document evidencing
its Subsidiary Guarantee may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Subsidiary Guarantee without notice to it and (3) covenants that
its Subsidiary Guarantee will not be discharged except by complete performance of the Subsidiary Guarantee. Each of the Subsidiary Guarantors further agrees that if at any time all or any part of any payment theretofore applied by any Person to its
Subsidiary Guarantee is, or must be, rescinded or returned for any reason whatsoever, including without limitation, the insolvency, bankruptcy or reorganization of the Company or any of the Subsidiary Guarantors, the Subsidiary Guarantee shall, to
the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Subsidiary Guarantee shall continue to be effective or be reinstated, as the case may be, as though
such application had not been made. 
 Each of the Subsidiary Guarantors shall be subrogated to all rights of the Holders and
the Trustee against the Company in respect of any amounts paid by such Subsidiary Guarantor pursuant to the provisions of the Indenture; provided, however, that such Subsidiary Guarantor, shall not be entitled to enforce or to receive
any payments arising out of, or based upon, such right of subrogation until all of the Notes and the Subsidiary Guarantees shall have been paid in full or discharged. 
 Section 1602. Execution and Delivery of Notation of Subsidiary Guarantee. 
 To further evidence its Subsidiary Guarantee set forth in Section 1601, each of the Subsidiary Guarantors hereby agrees that a notation relating to such Subsidiary Guarantee, substantially in the
form attached hereto as Annex B, shall be endorsed on each Note entitled to the benefits of the Subsidiary Guarantee authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an Officer of such Subsidiary
Guarantor, or in the case of a Subsidiary Guarantor that is a limited partnership, an Officer of the general partner of each Subsidiary Guarantor. Each of the Subsidiary Guarantors hereby agrees that the Subsidiary Guarantee set forth in
Section 1601 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation relating to its Subsidiary Guarantee. If any Officer of the Subsidiary Guarantor, or in the case of a Subsidiary Guarantor that is
a limited partnership, any Officer of the general partner of the Subsidiary Guarantor, whose signature is on the Indenture or a Note no longer holds that office at the time the Trustee authenticates such Note or at any time thereafter, the
Subsidiary Guarantee of such Note shall be valid nevertheless. The delivery of any Note by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Subsidiary Guarantees set forth in the Indenture on behalf of
the Subsidiary Guarantors. 
 Section 1603. Limitation on Subsidiary Guarantors’ Liability. 

Each Subsidiary Guarantor and by its acceptance hereof each Holder of a Note entitled to the benefits of the Subsidiary Guarantee hereby
confirm that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to its Subsidiary Guarantee not constitute a fraudulent transfer or conveyance for purposes of any Federal or State law. To effectuate the
foregoing intention, the Holders of a Note entitled to the benefits of the Subsidiary Guarantees and the Subsidiary Guarantors hereby irrevocably agree that the obligations of each Subsidiary Guarantor under its Subsidiary Guarantee shall be limited
to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the
obligations of such other Subsidiary Guarantor under its Subsidiary Guarantee, result in the obligations of such Subsidiary Guarantor under the Subsidiary Guarantee not constituting a fraudulent conveyance or fraudulent transfer under Federal or
State law. 
 Section 1604. Release of Subsidiary Guarantors from Guarantee. 

Each Subsidiary Guarantor will be released and relieved of any obligations under its Subsidiary Guarantee as set forth in the second
paragraph of Section 1117, and the Subsidiary Guarantee of a Subsidiary Guarantor will also be released immediately: 
 (1) upon any sale or other disposition of all or substantially all of the properties or assets of such Subsidiary Guarantor (including by way of merger or consolidation) to a Person that is not (either
before or after giving effect to such transaction) the Company or a Subsidiary Guarantor, if the sale or other disposition at the date thereof does not violate Section 1115; 

  
 85 

 (2) upon any sale or other disposition of the Capital Stock of such
Subsidiary Guarantor to a Person that is not (either before or after giving effect to such transaction) the Company or a Subsidiary Guarantor, if the sale or other disposition at the date thereof does not violate Section 1115 and such
Subsidiary Guarantor no longer qualifies as a Subsidiary of the Company as a result of such disposition; 
 (3)
upon designation of such Subsidiary Guarantor as an Unrestricted Subsidiary in accordance with Section 1118; 
 (4) upon Defeasance or Covenant Defeasance in accordance with Article Fourteen or satisfaction and discharge of the Indenture in accordance with Article Five; 

(5) upon the liquidation or dissolution of such Subsidiary Guarantor, provided that no Default or Event of Default
occurs as a result thereof or shall have occurred and is continuing; or 
 (6) in the case of any Restricted
Subsidiary which after the Issue Date is required to guarantee the notes pursuant to Section 1117, upon the release or discharge in full from its (x) guarantee of such Indebtedness or (y) obligation under such Credit Facility, in each
case, which resulted in such Restricted Subsidiary’s obligation to guarantee the Notes. 
 The Trustee shall deliver an
appropriate instrument evidencing any release of a Subsidiary Guarantor from the Subsidiary Guarantee upon receipt of a Company Request accompanied by an Officers’ Certificate and an Opinion of Counsel the Subsidiary Guarantor is entitled to
such release in accordance with the provisions of the Indenture. 
 Any Subsidiary Guarantor not released in accordance with the
provisions of the Indenture will remain liable for the full amount of principal of (and premium, if any, on) and interest on the Notes as provided in this Article Sixteen, subject to the limitations of Section 1603. 

Section 1605. Subsidiary Guarantor Contribution. 
 In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors hereby agree, inter se, that in the event any payment or distribution is made by any
Subsidiary Guarantor (a “Funding Guarantor”) under its Subsidiary Guarantee, such Funding Guarantor shall be entitled to a contribution from each other Subsidiary Guarantor (if any) in a pro rata amount based on the net
assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Company’s Obligations with respect to the Notes or any other Subsidiary
Guarantor’s obligations with respect to its Subsidiary Guarantee. 
 Section 1606. Subsidiary Guarantors May Consolidate, etc., on
Certain Terms. 
 A Subsidiary Guarantor may not sell or otherwise dispose of all or substantially all of its properties or
assets to, or consolidate with or merge with or into (regardless of whether such Subsidiary Guarantor is the surviving Person) another Person, other than the Company or another Subsidiary Guarantor, unless: 

(1) immediately after giving effect to such transaction, no Default or Event of Default exists; and 

(2) either: 
 (a) (i) such Subsidiary Guarantor is the surviving Person or (ii) the Person acquiring the properties or assets in any such sale or other disposition or the Person formed by or surviving any such
consolidation or merger (if other than such Subsidiary Guarantor) assumes all the obligations of such Subsidiary Guarantor under the Indenture (including its Subsidiary Guarantee), on the terms set forth herein, pursuant to a supplemental indenture
satisfactory to the Trustee; or 

  
 86 

 (b) such transaction at the date thereof does not violate the provisions of
Section 1115. 
 In case of any such consolidation, merger, sale or other disposition and upon the assumption by the
successor Person, by supplemental indenture, executed and delivered to the Trustee and satisfactory in form to the Trustee, of the Subsidiary Guarantee of such Subsidiary Guarantor and the due and punctual performance of all of the covenants and
conditions of the Indenture to be performed by the Subsidiary Guarantor, such successor Person will succeed to and be substituted for the Subsidiary Guarantor with the same effect as if it had been named herein as a Subsidiary Guarantor. Such
successor Person thereupon may cause to be signed any or all of the Subsidiary Guarantee notations to be endorsed upon all of the Notes issuable hereunder which theretofore shall not have been signed by such Subsidiary Guarantor and delivered to the
Trustee. All the Subsidiary Guarantees so issued will in all respects have the same legal rank and benefit under the Indenture as the Subsidiary Guarantees theretofore and thereafter issued in accordance with the terms of the Indenture as though all
of such Subsidiary Guarantees had been issued at the date of the execution hereof. 
  

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

 [Form of Reverse of Note] 

7.00% Senior Note due 2021 
 Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated. To the extent that any of the terms and provisions of this Note conflict
with the express provisions of the Indenture, the terms and provisions of the Indenture shall govern and be controlling. 
 (1)
INTEREST. Interest on the Notes will accrue at the rate of 7.00% per annum and will be payable semi-annually in arrears on June 15 and December 15, beginning on December 15, 2013. Interest on the Notes will accrue from the
date of original issuance or, if interest has already been paid, from the date it was most recently paid. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. If a payment date is a Legal Holiday at a Place of
Payment, payment may be made at that place on the next succeeding day that is not a Legal Holiday, and no interest shall accrue on such payment for the intervening period. The Company will pay interest (including post-petition interest in any
proceeding under any applicable Bankruptcy Law) on overdue principal and premium, if any, at the interest rate specified in the Notes to the extent lawful; and it will pay interest (including post-petition interest in any proceeding under any
applicable Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period) at the same rate to the extent lawful. 
 (2) METHOD OF PAYMENT. The Company will pay interest on the Notes (except Defaulted Interest) to the Persons who are registered Holders of Notes at the close of business on the June 1 or
December 1 next preceding the Interest Payment Date, even if such Notes are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 407 of the Indenture with respect to Defaulted Interest.
Holders must surrender Notes to the Paying Agent to collect payments of principal and premium, if any, due at Maturity. The Notes will be payable as to principal, premium, if any, and interest at the office or agency of the Company maintained for
such purpose in the City and State of New York, which, at the Issue Date, is the office of the Trustee located at 45 Broadway, 14th Floor, New York, New York 1006, or, at the option of the Company, payment of interest may be made by check mailed to
the Holders at their addresses set forth in the Security Register; provided that payment by wire transfer of immediately available funds will be required with respect to principal of and interest and premium, if any, on, all Global Notes and
all other Notes the Holders of which will have provided wire transfer instructions to the Company or the Paying Agent. Such payment will be in such coin or currency of the United States of America as at the time of payment is legal tender for
payment of public and private debts. 
 (3) PAYING AGENT AND SECURITY REGISTRAR. Initially, U.S. Bank National
Association, the Trustee under the Indenture, will act as Paying Agent and Security Registrar. The Company may change any Paying Agent or Security Registrar without notice to any Holder. The Company may act in any such capacity. 

(4) INDENTURE. The Notes are a series of Securities issued by the Company under an Indenture, dated as of June 11, 2013, by
and among the Company, the Subsidiary Guarantors parties thereto and the Trustee (the “Original Indenture”), as amended and supplemented by the First Supplemental Indenture thereto, dated as of June 11, 2013, by and among the
Company, the Subsidiary Guarantors parties thereto and the Trustee (the “Supplemental Indenture”), and designated as the “7.00% Senior Notes due 2021.” The Original Indenture, as amended and supplemented by the
Supplemental Indenture, and as further amended and supplemented as permitted thereunder, is referred to herein as the “Indenture.” The terms of the Notes include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of
the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Company. The Indenture does not limit the aggregate principal amount of Notes or any other series of Securities that may be
issued thereunder. 
 (5) OPTIONAL REDEMPTION. Except as described below, the Notes are not redeemable until
June 15, 2016. On and after June 15, 2016, the Company may redeem all or a part of the Notes, from time to time, at the following Redemption Prices (expressed as a percentage of principal amount) plus accrued and unpaid interest, if any,
on the Notes redeemed to the applicable Redemption Date (subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date), if redeemed during the twelve-month period beginning on
June 15 of the years indicated below: 

  
 A-3

					
	 Year
	  	Redemption
Price	 
	 2016
	  	 	105.250	% 
	 2017
	  	 	103.500	% 
	 2018
	  	 	101.750	% 
	 2019 and thereafter
	  	 	100.000	% 

 At any time or from time to time prior to June 15, 2016, the Company may also redeem all or a part
of the Notes, at a Redemption Price equal to the Make-Whole Price, subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Interest Payment Date. 

“Make-Whole Price” with respect to any Notes to be redeemed, means an amount equal to the greater of: 

(1) 100% of the principal amount of such Notes; and 

(2) the sum of the present values of (a) the Redemption Price of such Notes at June 15, 2016 (as set forth
above) and (b) the remaining scheduled payments of interest from the Redemption Date to June 15, 2016 (not including any portion of such payments of interest accrued as of the Redemption Date) discounted back to the Redemption Date on a
semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus 50 basis points; 

plus, in the case of both (1) and (2), accrued and unpaid interest on such Notes, if any, to the Redemption Date. 

“Comparable Treasury Issue” means, with respect to Notes to be redeemed, the U.S. Treasury security selected by an
Independent Investment Banker as having a maturity most nearly equal to the period from the Redemption Date to June 15, 2016, that would be utilized at the time of selection and in accordance with customary financial practice, in pricing new
issues of corporate debt securities of a comparable maturity; provided that if such period is less than one year, then the U.S. Treasury security having a maturity of one year shall be used. 

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury
Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such
Reference Treasury Dealer Quotations. 
 “Independent Investment Banker” means J.P. Morgan Securities LLC or
one of its successors, or, if such firm or its successors, if any, as the case may be, are unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Company.

 “Reference Treasury Dealer” means J.P. Morgan Securities LLC and a Primary Treasury Dealer designated by
J.P. Morgan Securities, LLC and two additional primary Government Securities dealers in New York City (each a “Primary Treasury Dealer”) selected by the Company, and their respective successors; provided, however, that
if any such firm or any such successor, as the case may be, shall cease to be a primary Government Securities dealer in New York City, the Company shall substitute therefor another Primary Treasury Dealer. 

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date,
the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at
5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 
 “Treasury
Rate” means, with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated
“H.15(159)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and that establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the
caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable 

  
 A-4

 Treasury Issue (if no maturity is within three months before or after the stated maturity, yields for the
two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined, and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding to the nearest month) or
(2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semi-annual equivalent yield to maturity of the Comparable Treasury
Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day
preceding the Redemption Date. 
 The notice of redemption with respect to the foregoing redemption need not set forth the
Make-Whole Price but only the manner of calculation thereof. The Company will notify the Trustee of the Make-Whole Price with respect to any redemption promptly after the calculation, and the Trustee shall not be responsible for such calculation.

 Prior to June 15, 2016, the Company may on any one or more occasions redeem up to 35% of the principal amount of the
Notes, with all or a portion of the net cash proceeds of one or more Equity Offerings at a Redemption Price equal to 107.000% of the principal amount thereof, plus accrued and unpaid interest, if any, on the Notes redeemed to the Redemption Date
(subject to the right of Holders of record on the relevant record date to receive interest due on the relevant Interest Payment Date); provided that: 
 (1) at least 65% of the aggregate principal amount of the Notes issued on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains Outstanding after each such redemption; and

 (2) the redemption occurs within 180 days after the closing of such Equity Offering. 

Notice of any redemption with the net cash proceeds of one or more an Equity Offerings may be given prior to the completion of the
related Equity Offering, and any such redemption or notice may at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to completion of the related Equity Offering. 

In the event that Holders of at least 90% of the aggregate principal amount of the Outstanding Notes accept a Change of Control Offer and
the Company (or any third party making such Change of Control Offer, in lieu of the Company, as described in the sixth paragraph of Section 1110 of the Supplemental Indenture) purchases all of the Notes held by such Holders, the Company will
have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following a Change of Control Payment Date, to redeem all, but not less than all, of the Notes that remain Outstanding at a Redemption Price
equal to the Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest, if any, on the Notes that remain Outstanding, to the date of redemption (subject to the right of Holders on the
relevant record date to receive interest due on the relevant Interest Payment Date). 
 Unless the Company defaults in the
payment of the Redemption Price, interest, if any, will cease to accrue on the Notes or portions thereof called for redemption on the applicable Redemption Date. 
 (6) NOTE PURCHASES; MANDATORY REDEMPTION. The Company may at any time and from time to time purchase Notes in the open market and otherwise. The Company is not required to make mandatory redemption
or sinking fund payments with respect to the Notes. However, under certain circumstances, the Company may be required to offer to purchase Notes pursuant to Section 1110 or 1115 of the Supplemental Indenture. 

(7) REPURCHASE AT THE OPTION OF HOLDER. 
 (a) If there is a Change of Control, the Company will be required to make an offer (a “Change of Control Offer”) to each Holder to repurchase all or any part (equal to $2,000 or an
integral multiple of $1,000 in excess $2,000) of each Holder’s Notes at a purchase price in cash equal to not less than 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, thereon to the date of purchase,
subject to the rights of 

  
 A-5

 
Holders on the relevant record date to receive interest due on the relevant Interest Payment Date (the “Change of Control Payment”). Within 30 days following any Change of
Control, the Company will send a notice to each Holder setting forth the procedures governing the Change of Control Offer as required by the Indenture. 
 (b) If the Company or a Restricted Subsidiary of the Company consummates any Asset Sales, within 10 Business Days of each date on which the aggregate amount of Excess Proceeds exceeds $20.0 million, the
Company will make an offer (an “Asset Sale Offer”) to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in the Indenture with respect
to offers to purchase or redeem with the proceeds of sales of assets pursuant to Section 1115 of the Supplemental Indenture to purchase the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased
out of the Excess Proceeds. The offer price in any Asset Sale will be equal to 100% of the principal amount plus accrued and unpaid interest, if any, to the date of purchase, in accordance with the procedures set forth in the Indenture. If any
Excess Proceeds remain unapplied after the consummation of an Asset Sale Offer, the Company (or any Restricted Subsidiary) may use the Excess Proceeds for any purpose not otherwise prohibited by the Indenture. If the aggregate principal amount of
Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds, the Company will use the Excess Proceeds to purchase the Notes and such other pari passu Indebtedness on a pro
rata basis. Holders of Notes that are the subject of an offer to purchase will receive notice of an Asset Sale Offer from the Company prior to any related purchase date and may elect to have such Notes purchased by completing the form entitled
“Option of Holder to Elect Purchase” attached to the Notes. 
 (8) NOTICE OF REDEMPTION. Notice of redemption
will sent at least 30 days but not more than 60 days before the Redemption Date to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be sent more than 60 days prior to a Redemption Date if the
notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of the Indenture. Notes in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $ 1,000, unless all of the Notes held by
a Holder are to be redeemed. 
 (9) DENOMINATIONS, TRANSFER, EXCHANGE. The Notes are in registered form
without coupons in denominations of $2,000 and integral multiples of $1,000 in excess of $2,000. The transfer of Notes may be registered and Notes may be exchanged as provided in the Indenture. The Security Registrar and the Trustee may require a
Holder, among other things, to furnish appropriate endorsements and transfer documents in connection with a transfer of its Notes, and the Company may require a Holder to pay any taxes and fees required by law or permitted by the Indenture. The
Company need not exchange or register the transfer of any Note or portion of a Note selected for redemption, except for the unredeemed portion of any Note being redeemed in part. Also, the Company need not exchange or register the transfer of any
Notes for a period of 15 days before a selection of Notes to be redeemed or during the period between a record date and the corresponding Interest Payment Date. 
 (10) PERSONS DEEMED OWNERS. The registered Holder of a Note may be treated as its owner for all purposes. 
 (11) AMENDMENT, SUPPLEMENT AND WAIVER. Subject to certain exceptions, the Indenture and the Notes may be amended or supplemented with the consent of the Holders of at least a majority in
aggregate principal amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, Notes), and any existing default or compliance with any provision of
the Indenture or the Notes may be waived with the consent of the Holders of at least a majority in aggregate principal amount of the Notes then Outstanding (including, without limitation, consents obtained in connection with a purchase of, or tender
offer or exchange offer for, Notes). Without the consent of any Holder of a Note, the Indenture or the Notes may be amended or supplemented to, among other things, cure any ambiguity, defect or inconsistency, or make any change that does not
adversely affect the rights or interests of any such Holder. 
 (12) DEFAULTS AND REMEDIES. In the case of an Event of
Default arising from events of bankruptcy or insolvency specified in clause (9) or (10) of Section 601 of the Supplemental Indenture, all Outstanding Notes will become due and payable immediately without further action or notice. If
any other Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the then Outstanding Notes may declare all the Notes to be due and payable immediately by notice in writing to the
Company specifying the Event of Default. Holders of the Notes may not enforce the Indenture or the Notes except as provided 

  
 A-6

 
in the Indenture. Subject to certain limitations, Holders of at least a majority in aggregate principal amount of the then Outstanding Notes may direct the Trustee in its exercise of any trust or
power. The Trustee may withhold from Holders of the Notes notice of any Default or Event of Default (except a Default or Event of Default relating to the payment of principal, premium or interest) if and so long as the Trustee in good faith
determines that withholding the notice is in the interests of the Holders of the Notes. The Company is required to deliver to the Trustee annually an Officers’ Certificate regarding the compliance with the Indenture, and the Company is
required, within five Business Days after becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying such Default or Event of Default. The Holders of at least a majority in aggregate principal amount of the
Notes then Outstanding may on behalf of the Holders of all of the Notes waive any past default and its consequences under the Indenture, except a default in the payment of interest or any premium on, or the principal of, the Notes and except as
provided in Section 613(2) of the Supplemental Indenture. The Holders of at least a majority in aggregate principal amount of the then Outstanding Notes will have the right to direct the time, method and place of conducting any proceeding for
any remedy available to the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or the Indenture, or that may involve the Trustee in personal liability, and may take any other action it
deems proper that is not inconsistent with any such direction received from Holders of Notes. 
 (13) TRUSTEE DEALINGS WITH
COMPANY. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the
Trustee. 
 (14) NO RECOURSE AGAINST OTHERS. No director, officer, employee, incorporator, stockholder, member, manager
or partner of the Company or any Subsidiary Guarantor, as such, will have any liability for any obligations of the Company or any Subsidiary Guarantor under the Notes, the Indenture or the Subsidiary Guarantees or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes. 

(15) AUTHENTICATION. This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating
agent. 
 (16) ABBREVIATIONS. Customary abbreviations may be used in the name of a Holder or an assignee, such as: TEN
COM (= tenants in common), TEN ENT (= tenants by the entireties), IT TEN (=joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

(17) CUSIP NUMBERS. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the
Company has caused CUSIP and CINS numbers to be printed on the Notes, and the Trustee may use CUSIP and CINS numbers in notices of redemption as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed
on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon. 
 (18) GOVERNING LAW. THE LAW OF THE STATE OF NEW YORK WILL GOVERN AND BE USED TO CONSTRUE AND ENFORCE THE INDENTURE AND THIS NOTE. 

The Company will furnish to any Holder upon written request and without charge a copy of the Original Indenture and the Supplemental
Indenture. Requests may be made to:
