trustee (the “Trustee”). 
 WHEREAS, the Company has duly authorized, executed and delivered the Base Indenture (as
hereinafter defined) to provide for the issuance from time to time of the Company’s debentures, notes or other evidences of indebtedness, to be issued in one or more series, and the Guarantee by each of the Guarantors of the Securities, as the
Base Indenture provides; 
 WHEREAS, Section 9.1 of the Base Indenture provides, among other things, that the Company, the
Guarantors and the Trustee may enter into indentures supplemental to the Base Indenture, without the consent of any Holders of Securities, to establish the form or terms of any Security as permitted by Sections 201 and 301 of the Base Indenture;

 WHEREAS, pursuant to Sections 2.1 and 3.1 of the Base Indenture, the Company, the Guarantors and the Trustee entered into a
First Supplemental Indenture on March 4, 2011 (the “Original First Supplemental Indenture”), to establish the form and terms, and to provide for the issuance, of a series of senior notes designated as 6.750% Senior Notes due 2021 in
an aggregate principal amount of $475,000,000 (the “Initial Securities”); 
 WHEREAS, from time to time subsequent to
the Issue Date, the Company may, if permitted to do so pursuant to the terms of the Original First Supplemental Indenture, the Initial Securities and the terms of its other indebtedness existing on such future date, issue additional senior notes of
the same series as the Initial Securities (the “Additional Securities”), in either a registered or a private offering under the Securities Act, pursuant to the Original First Supplemental Indenture; 

WHEREAS, Section 9.01(9) of the Original First Supplemental Indenture allows the Company, the Guarantors and the Trustee, without
the consent of the holders of any Securities (as hereinafter defined), to supplement or amend the Original First Supplemental Indenture to provide for the issuance of Additional Securities in accordance with the Original First Supplemental
Indenture; 
 WHEREAS, Section 9.01(1) of the Original First Supplemental Indenture allows the Company, the Guarantors and
the Trustee, without the consent of the holders of any Securities, to supplement or amend the Original First Supplemental Indenture to provide to cure any ambiguity, defect or inconsistency; 

WHEREAS, the Company desires to amend the Original First Supplemental Indenture to provide for the issuance of Additional Securities in
an aggregate principal amount of $200,000,000 in a transaction exempt from the registration requirements of the Securities Act (such Additional Securities, the “Initial Private Securities”) and to correct certain ambiguities, defects and
inconsistencies; 
 WHEREAS, the Company and the Guarantors are members of the same consolidated group of companies; the

unconditional and joint and several Guarantee of the Securities; 
 WHEREAS, 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;

 WHEREAS, this Supplemental Indenture restates in their entirety the terms of the Original
First Supplemental Indenture as amended by this Supplemental Indenture and does not incorporate the terms of the Base Indenture or the Original First Supplemental Indenture. The changes, modifications and supplements to the Base Indenture affected
by this Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Securities, except as otherwise provided herein, and shall not apply to any other securities that may be issued under the Base Indenture
unless a supplemental indenture with respect to such other securities specifically incorporates such changes, modifications and supplements; and 
 WHEREAS, all things necessary have been done to make the Securities, 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 Securities have been executed by the Company and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of the

be deemed to be control by the owner thereof. 
 “Applicable Premium” means, at any Redemption Date, the excess
of (A) the present value at such Redemption Date of (1) the Redemption Price of the Securities on March 1, 2016 (such redemption price being set forth in Section 3.07(a)) plus (2) all required remaining scheduled

sale, exchange, transfer or other disposition of accounts receivable in connection with any Credit Facility permitted to be incurred hereunder; 
 (2) any disposition of assets in trade or exchange for assets of comparable Fair Market Value used or usable in any Permitted Business (including, without limitation, the trade or exchange for a
controlling interest in another business or all or substantially all of the assets or operating line of a business, in each case, engaged in a Permitted Business or for other non-current assets to be used in a Permitted Business, including, without
limitation, assets or Investments of the nature or type described in clause (13) of the definition of “Permitted Investments”); provided that (x) if the Fair Market Value of the assets so disposed of, in a single

the disposition of assets received in settlement of debts accrued in the ordinary course of business; 

  
 4 








 (11) the creation or perfection of a Lien on any assets (or any income or
profit therefrom) of the Company or any of its Restricted Subsidiaries that is not prohibited by any covenant of this Supplemental Indenture;

 Section 1.06 Effect of Supplemental Indenture 

This Supplemental Indenture restates in their entirety the terms of the Base Indenture as supplemented by this Supplemental Indenture and
the Original First Supplemental Indenture and does not incorporate the terms of the Base Indenture, other than in connection to the rights of the Trustee, or the Original First Supplemental Indenture. The changes, modifications and supplements to
the Base Indenture effected by this Supplemental Indenture shall be applicable only with respect to, and shall only govern the terms of, the Securities, except as otherwise provided herein, and shall not apply to any other securities that may be
issued under the Base Indenture unless a supplemental indenture with respect to such other securities specifically incorporates such changes, modifications and supplements. Notwithstanding the foregoing, the Trustee shall be entitled to the same
rights, benefits, protections, indemnifications and immunities afforded to it pursuant to the Base Indenture. 
 ARTICLE 2

 THE SECURITIES 

Section 2.01 Form and Dating 
 (a) General. The Initial Securities and the Trustee’s certificate of authentication shall be substantially in the form of Exhibit A hereto. Certain provisions relating to the Initial
Private Securities, the Private Exchange Securities and the Exchange Securities, including, without limitation, the issuance, transfer and exchange of such Securities are set forth in the Rule 144A/Regulation S Appendix attached hereto (the
“Appendix”), which is hereby incorporated in and expressly made part of this Supplemental Indenture. The Initial Private Securities and the Trustee’s certificate of authentication therefor shall be substantially in the form of
Exhibit 1 to the Appendix, which is hereby incorporated in and expressly made a part of this Supplemental Indenture. Any notation of Subsidiary Guarantee shall be substantially in the form of Exhibit B hereto, and shall be notated on the
Securities. The Securities may have notations, legends or endorsements required by law, stock exchange rule or usage. Each Security shall be dated the date of its authentication. The Securities shall be in minimum denominations of $2,000 and
integral multiples of $1,000 in excess thereof. The terms and provisions contained in the Securities shall constitute, and are hereby expressly made, a part of this Supplemental Indenture and the Company, the Guarantors and the Trustee, by their
execution and delivery of this Supplemental Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Security or any Subsidiary Guarantee conflicts with the express provisions of
this Supplemental Indenture, the provisions of this Supplemental Indenture (to the extent permitted by law) shall govern and be controlling. 
 (b) Global Securities. Securities issued in global form shall be substantially in the form of Exhibit A (or, with respect to Initial Private Securities, Exhibit 1 to the Appendix)
attached hereto (including the Global Security Legend thereon and the “Schedule of Exchanges of Interests in the Global Security” attached thereto). Securities issued in definitive form shall be substantially in the form of Exhibit
A (or, with respect to Initial Private Securities, Exhibit 1 to the Appendix) attached hereto (but without the Global Security Legend thereon and without the “Schedule of Exchanges of Interests in the Global Security” attached
thereto). Each Global Security shall represent such of the outstanding Securities as shall be specified therein, and each shall provide that it shall represent the aggregate principal amount of outstanding Securities from time to time endorsed
thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Security to reflect the
amount of any increase or decrease in the aggregate principal amount of outstanding Securities represented thereby shall be made by the Trustee or the Securities Custodian, at the direction of the Trustee, in accordance with instructions given by
the Holder thereof as required by Section 2.06 hereof. 

  
 27 









 (c) Definitive Securities. Notwithstanding any other provision of this
Article 2, any issuance of Definitive Securities shall be at the Company’s discretion, except in the specific circumstances set forth in Section 2.06(a) hereof. 
 Section 2.02 Execution and Authentication 
 (a) An Officer shall sign
the Securities for the Company by manual or facsimile signature. One Officer shall sign each notation of Subsidiary Guarantee for each Guarantor by manual or facsimile signature. 

(b) If an Officer whose facsimile signature is on a Security no longer holds that office at the time the Trustee authenticates the
Security, the Security shall be valid nevertheless. 
 (c) A Security shall not be valid until an authorized signatory of the
Trustee manually authenticates the Security. The signature of the Trustee on a Security shall be conclusive evidence that such Security has been duly and validly authenticated and issued under this Supplemental Indenture. 

(d) The Trustee shall authenticate and deliver: (1) Initial Securities for original issue in an aggregate principal amount of
$475,000,000 and (2) if and when issued, Additional Securities (which may be issued in either a registered or a private offering under the Securities Act), in each case upon a written order of the Company signed by one Officer of the Company.
Such order shall specify the amount of the Securities to be authenticated and the date on which the issue of Securities is to be authenticated and whether the Securities are to be in global or definitive form. The Trustee shall also be entitled to
receive, and (subject to Section 7.01) shall be fully protected in relying upon, in addition to the documents required by Section 11.04, an Opinion of Counsel stating: that such Initial Securities when authenticated and delivered by the
Trustee and issued by the Company in the manner and subject to any conditions and assumptions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company and, if applicable, the Guarantors, enforceable
in accordance with their terms, subject to the following limitations: (i) bankruptcy, insolvency, moratorium, reorganization, liquidation, fraudulent conveyance or transfer and other similar laws of general applicability relating to or
affecting the enforcement of creditors’ rights, or to general equity principles, (ii) the availability of equitable remedies being subject to the discretion of the court to which application therefor is made; and (iii) such other
usual and customary matters as shall be specified in such Opinion of Counsel. The Company may issue Additional Securities under this Supplemental Indenture subsequent to the Issue Date, subject to Section 4.03 of this Supplemental
Indenture; provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code. 

(e) The Trustee shall have the right to decline to authenticate and deliver any Additional Securities under this Section if the Trustee
determines that such action may not lawfully be taken by the Company or if the Trustee in good faith by its board of directors or board of trustee, executive committee, or a trust committee of directors or trustees or Trust Officers shall determine
that such action would expose the Trustee to personal liability to existing Holders. 
 (f) The Trustee may appoint an agent
(the “Authenticating Agent”) reasonably acceptable to the Company to authenticate the Securities. Unless limited by the terms of such appointment, any such Authenticating Agent may authenticate Securities whenever the Trustee may do so.
Each reference in this Supplemental Indenture to authentication by the Trustee includes authentication by such agent. 

  
 28 









 Section 2.03 Registrar and Paying Agent 

(a) The Company shall at all times maintain in the continental United States an office or agency where Securities may be presented for
registration of transfer or for exchange (the “Registrar”), and it shall likewise maintain an office or agency where Securities may be presented for payment (the “Paying Agent”). The Registrar shall keep a register of the
Securities and of their transfer and exchange. The Company may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar, and the term “Paying Agent” includes any such
additional paying agent. 
 (b) The Company or any of its Subsidiaries may act as Paying Agent, subject to the provisions of
Section 4.15, or as Registrar. Any Paying Agent or Registrar may resign as such upon 30 days’ prior written notice to the Company and the Trustee; upon resignation of any Paying Agent or Registrar, the Company shall appoint a
successor Paying Agent or Registrar, as the case may be, complying with the requirements of this Section 2.03, no later than 30 days thereafter and shall provide notice to the Trustee of such successor Paying Agent or Registrar.

 (c) The Company initially appoints The Bank of New York Mellon Trust Company, N.A. as Registrar and Paying Agent for the
Securities at its Corporate Trust Office. The place of payment with respect to the Securities, in addition to the Corporate Trust Office of the Trustee, shall be New York, New York, and at such time, if ever, as the Securities are no longer
represented by one or more Global Securities, the Company shall appoint and maintain a Paying Agent in New York, New York, the intention of the Company being that, after giving effect to the procedures of the Depositary respecting payments on Global
Securities, the Securities shall at all times be payable in New York, New York. 
 (d) The immunities, protections and
exculpations available to the Trustee under this Supplemental Indenture shall also be available to each Agent, and the Company’s obligations under Section 7.07 to compensate and indemnify the Trustee shall extend likewise to each
Agent. 
 Section 2.04 [Intentionally
Omitted] 
 Section 2.05 Holder Lists 

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and
addresses of Holders. If the Trustee is not the Registrar, the Company shall furnish to the Trustee, in writing at least seven Business Days before each Interest Payment Date and at such other times as the Trustee may request in writing, a list in
such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders. 
 Section 2.06 Transfer and
Exchange 
 (a) Transfer and Exchange of Global Securities. A Global Security may not be transferred as a whole except
by the Depositary to a nominee of the Depositary, by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to a successor Depositary or a nominee of such successor Depositary.
Global Securities also may be exchanged or replaced, in whole, as provided in Section 2.07 hereof. Owners of beneficial interests in Global Securities shall not be entitled to receive Definitive Securities unless: 

(1) the Company delivers to the Trustee and the Registrar notice from the Depositary that it is unwilling or unable to
continue to act as Depositary or that it is no longer a clearing agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days; 

  
 29 









 (2) there has occurred and is continuing an Event of Default and the
Depositary notifies the Trustee and the Registrar of its decision to exchange the Global Securities for Definitive Securities; or 
 (3) any such owner requests (through a Direct or Indirect Participant) an exchange of its beneficial interest in a Global Security for a Definitive Security, and the Depositary gives the Trustee and the
Registrar, in accordance with the Applicable Procedures, at least 20 days’ prior notice of the request. 
 Upon the
occurrence of any of the events in clause (1), (2) or (3) above, Definitive Securities shall be issued in such names and authorized denominations as the Depositary shall instruct the Trustee and the Registrar in accordance with the
Applicable Procedures. Neither the Company, the Guarantors nor the Trustee or the Registrar will be liable for any delay by the Depositary in identifying the owners of beneficial interests in a Global Security, and each of the Company, the
Guarantors, the Trustee and the Registrar may conclusively rely on, and will be protected in relying on, instructions from the Depository for all purposes of this Supplemental Indenture. 

(b) Transfer and Exchange of Beneficial Interests in the Global Securities. The transfer and exchange of beneficial interests in
the Global Securities shall be effected through the Depositary, in accordance with the provisions of this Supplemental Indenture and the Applicable Procedures. Beneficial interests in any Global Security may be transferred to Persons who take
delivery thereof in the form of a beneficial interest in a Global Security. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b) and
Section 2.06(d) hereof. 
 (c) Transfer or Exchange of Beneficial Interests for Definitive Securities. If any
holder of a beneficial interest in a Global Security proposes to exchange such beneficial interest for a Definitive Security or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Definitive Security, then,
upon satisfaction of the conditions set forth in Section 2.06(b) hereof, the Trustee will cause the aggregate principal amount of the applicable Global Security to be reduced accordingly pursuant to Section 2.06(g) hereof,
and the Company will execute and the Trustee will authenticate and deliver to the Person designated in the instructions a Definitive Security in the appropriate principal amount. Any Definitive Security issued in exchange for a beneficial interest
pursuant to this Section 2.06(c) will be registered in such name or names and in such authorized denomination or denominations as the holder of such beneficial interest requests through instructions to the Registrar from or through the
Depositary and the Participant or Indirect Participant. The Trustee will deliver such Definitive Securities to the Persons in whose names such Securities are registered. 
 (d) Transfer and Exchange of Definitive Securities for Beneficial Interests. A Holder of a Definitive Security may exchange such Security for a beneficial interest in a Global Security or transfer
such Definitive Security to a Person who takes delivery thereof in the form of a beneficial interest in a Global Security at any time. Upon receipt of a request for such an exchange or transfer, the Trustee shall cancel the applicable Definitive
Security and the Registrar shall increase or cause to be increased the aggregate principal amount of one of the Global Securities. 
 (e) Transfer and Exchange of Definitive Securities for Definitive Securities. Upon request by a Holder of Definitive Securities and such Holder’s compliance with the provisions of this
Section 2.06(e), the Registrar shall register the transfer or exchange of Definitive Securities. Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Registrar the


  
 30 









 
Definitive Securities duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in
writing. A Holder of Definitive Securities may transfer such Securities to a Person who takes delivery thereof in the form of a Definitive Security. 
 (f) Legend. The following legend shall appear on the face of each Global Security issued under this Supplemental Indenture unless specifically stated otherwise in the applicable provisions of this
Supplemental Indenture: 
 THIS GLOBAL SECURITY IS HELD BY THE DEPOSITARY (AS DEFINED IN THE SUPPLEMENTAL INDENTURE GOVERNING THIS SECURITY) OR
ITS NOMINEE IN CUSTODY FOR THE BENEFIT OF THE BENEFICIAL OWNERS HEREOF, AND IS NOT TRANSFERABLE TO ANY PERSON UNDER ANY CIRCUMSTANCES EXCEPT THAT (I) THE REGISTRAR MAY MAKE SUCH NOTATIONS HEREON AS MAY BE REQUIRED PURSUANT TO SECTION
2.06 OF THE SUPPLEMENTAL INDENTURE, (II) THIS GLOBAL SECURITY MAY BE EXCHANGED IN WHOLE BUT NOT IN PART PURSUANT TO SECTION 2.06(a) OF THE SUPPLEMENTAL INDENTURE AND (III) THIS GLOBAL SECURITY MAY BE DELIVERED TO THE TRUSTEE FOR
CANCELLATION PURSUANT TO SECTION 2.10 OF THE SUPPLEMENTAL INDENTURE. 
 UNLESS AND UNTIL IT IS EXCHANGED IN WHOLE OR IN PART FOR
SECURITIES IN DEFINITIVE FORM, THIS SECURITY MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE OF THE DEPOSITARY OR BY A NOMINEE OF THE DEPOSITARY TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR
ANY SUCH NOMINEE TO A SUCCESSOR DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR DEPOSITARY. UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY (55 WATER STREET, NEW YORK, NEW YORK) (“DTC”) TO THE
COMPANY OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO. OR SUCH OTHER NAME AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC (AND ANY PAYMENT IS
MADE TO CEDE & CO. OR SUCH OTHER ENTITY AS MAY BE REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL INASMUCH AS THE REGISTERED OWNER HEREOF,
CEDE & CO., HAS AN INTEREST HEREIN. 
 (g) Cancellation and/or Adjustment of Global Securities. At such time as
all beneficial interests in a particular Global Security have been exchanged for Definitive Securities or a particular Global Security has been redeemed, repurchased or canceled in whole and not in part, each such Global Security shall be returned
to or retained and canceled by the Trustee in accordance with Section 2.10 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery
thereof in the form of a beneficial interest in another Global Security or for Definitive Securities, the principal amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global
Security by the Trustee or by the Securities Custodian at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a
beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an endorsement shall be made on such Global Security by the Trustee or by the Securities Custodian at the direction of the Trustee to
reflect such increase. 
 (h) General Provisions Relating to Transfers and Exchanges. 

  
 31 









 (1) To permit registrations of transfers and exchanges, the Company shall
execute and the Trustee shall authenticate Global Securities and Definitive Securities upon the Company’s order or at the Registrar’s request. 
 (2) No service charge shall be made to a holder of a beneficial interest in a Global Security or to a Holder of a Definitive Security for any registration of transfer or exchange, but the Company or the
Trustee may require payment of a sum sufficient to cover any transfer tax or similar governmental charge or other fee required by law and payable in connection therewith (other than any such transfer taxes or similar governmental charge payable upon
exchange or transfer pursuant to Sections 2.09, 3.06, 3.07, 4.07 and 4.12 hereof). 
 (3) All Global Securities and Definitive Securities issued upon any registration of transfer or exchange of Global Securities or Definitive Securities shall be the valid obligations of the Company,
evidencing the same debt, and entitled to the same benefits under this Supplemental Indenture, as the Global Securities or Definitive Securities surrendered upon such registration of transfer or exchange. 

(4) None of the Company, the Trustee or the Registrar shall be required (A) to issue, to register the transfer of or
to exchange any Securities during a period of 15 days before the day of any selection of Securities for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer
of or to exchange any Securities so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part or (C) to register the transfer of or to exchange a Security between a record date and the
next succeeding Interest Payment Date. 
 (5) Prior to the due presentation for registration of transfer of any
Security, the Company, any Guarantor, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal,
interest, and premium (if any) on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Trustee, the Paying Agent or the Registrar shall be affected by notice to the contrary.

 (6) The Trustee shall authenticate Global Securities and Definitive Securities upon receipt of a written order
of the Company signed by one of its Officers and in accordance with the other provisions of Section 2.02 hereof to the extent applicable. 
 (7) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be
submitted by facsimile. 
 Section 2.07 Replacement Securities 

(a) If any mutilated Security is surrendered to the Registrar or the Company and the Registrar and the Company receive evidence to their
satisfaction of the destruction, loss or theft of any Security, the Company will issue and the Trustee, upon receipt of a written order of the Company (which need not be in the form of an Officers’ Certificate), will authenticate a replacement
Security if the Registrar’s and the Company’s reasonable requirements are met. If required by the Registrar or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of the Registrar, the Trustee
and the Company to protect the Company, the Trustee, the Registrar, any other Agent and any Authenticating Agent from any loss that any of them may suffer if a Security is replaced. 

  
 32 









 (b) Every replacement Security is an additional obligation of the Company and will be
entitled to all of the benefits of this Supplemental Indenture equally and proportionately with all other Securities duly issued hereunder. 

Section 2.08 Outstanding Securities 
 (a) The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in
a Global Security effected by the Trustee in accordance with the provisions hereof, and those described in this Section as not outstanding. Except as set forth in Section 11.06 hereof, a Security does not cease to be outstanding because
the Company or an Affiliate of the Company holds the Security. 
 (b) If a Security is replaced pursuant to
Section 2.07 hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser. 
 (c) If the principal amount of any Security is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue. 

(d) If the Paying Agent (other than the Company, a Subsidiary or an Affiliate of any thereof) holds, on a Redemption Date or maturity
date, money sufficient to pay Securities payable on that date, then on and after that date such Securities will be deemed to be no longer outstanding and will cease to accrue interest. 
 Section 2.09 Temporary Securities 
 Until Definitive Securities are
ready for delivery, the Company may prepare and the Trustee shall authenticate temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Company considers appropriate for
temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Securities in exchange for temporary Securities. Holders of temporary Securities shall in all respects be entitled to the same
benefits under this Supplemental Indenture as a holder of Definitive Securities. 
 Section 2.10 Cancellation 

The Company at any time may deliver Securities to the Trustee or any Registrar for cancellation. The Registrar and the Paying Agent shall
forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee or the Registrar and no one else shall cancel and dispose of, in accordance with its policies (but subject to the record
retention requirements of the Exchange Act), all Securities surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall deliver a certificate of such disposal to the Company from time to time upon written
request. The Company may not issue new Securities to replace Securities it has redeemed, paid or delivered to the Trustee or the Registrar for cancellation. 
 Section 2.11 Defaulted Interest 
 If the Company defaults in a payment
of interest (“Defaulted Interest”) on the Securities, the Company shall pay Defaulted Interest (as provided in Section 4.01) in any lawful manner. The Company may pay the Defaulted Interest to the Persons who are Holders on a
subsequent special record date. The Company shall fix or cause to be fixed (or upon the Company’s failure to do so the Trustee shall fix pursuant to a written instruction of Holders of at least a majority in principal amount of the Securities)


  
 33 









 
any such special record date and payment date to the reasonable satisfaction of the Trustee which special record date shall not be less than 10 days prior to the payment date for such Defaulted
Interest and the Company, or at the Company’s request, the Trustee, shall promptly mail or cause to be mailed to each Holder a notice that states the special record date, the payment date and the amount of Defaulted Interest to be paid. The
Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to
the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when so deposited to be held in trust for
the benefit of the Persons entitled to such Defaulted Interest as provided in this Section 2.11. 
 Section 2.12 CUSIP
Numbers 
 The Company in issuing the Securities may use “CUSIP,” “ISIN” or similar numbers (if then
generally in use) and, if so, the Trustee shall use such 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 numbers
either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company shall promptly notify the Trustee, in writing, of any change in any CUSIP or ISIN number. 

ARTICLE 3 

REDEMPTION 
 Section 3.01
Notices to Trustee 
 (a) If the Company elects to redeem Securities pursuant to Section 3.07 hereof, it shall
notify the Trustee in writing of the Redemption Date and the principal amount of Securities to be redeemed. The Company shall give each notice to the Trustee provided for in this Section 3.01 at least 15 days before notice of such
Redemption Date is given to the Holders unless the Trustee consents to a shorter period. If such redemption is to be effected pursuant to Section 3.07(b) or 3.07(d), then such notice shall be accompanied by an Officers’
Certificate to the effect that such redemption will comply with the conditions therein. 
 (b) If fewer than all the Securities
are to be redeemed, the record date relating to such redemption shall be selected by the Company and set forth in the related notice given to the Trustee, which record date shall be not less than 15 days after the date of such notice. 

Section 3.02 Selection of Securities to Be Redeemed 
 In the case of any partial redemption, selection of the Securities for redemption will be made by the Trustee in compliance with the requirements of the principal national securities exchange, if any, on
which the Securities are listed or, if the Securities are not listed, then on a pro rata basis, by such method as the Trustee shall deem to be fair and appropriate and consistent with the applicable procedures of the Depositary. The Trustee shall
make the selection from outstanding Securities not previously called for redemption. The Trustee may select for redemption portions of the principal of Securities that have denominations larger than $2,000. Securities and portions of them the
Trustee selects shall be in minimum amounts of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Supplemental Indenture that apply to Securities called for redemption also apply to portions of Securities called for
redemption. The Trustee shall notify the Company promptly of the Securities or portions of Securities to be redeemed. The Trustee may rely upon information provided by the Registrar for purposes of this Section 3.02. 

  
 34 









 Section 3.03 Notice of Redemption 

(a) At least 30 days but not more than 60 days before a date for redemption of Securities, the Company shall mail a notice of redemption
by first-class mail to each Holder of Securities to be redeemed at such Holder’s registered address, except that redemption notices may be mailed more than 60 days prior to the Redemption Date if the notice is mailed in connection with a
defeasance of the Securities or a satisfaction and discharge of this Supplemental Indenture in accordance with Article 8. 
 (b) The notice shall identify the Securities to be redeemed and shall state: 
 (1) the Redemption Date; 
 (2) the Redemption Price (if then
determined and otherwise the basis for its determination); 
 (3) the name and address of the Paying Agent where
Securities are to be surrendered; 
 (4) that Securities called for redemption must be surrendered to the Paying
Agent to collect the Redemption Price; 
 (5) if fewer than all the outstanding Securities are to be redeemed,
the identification and principal amounts of the particular Securities to be redeemed; 
 (6) that, unless the
Company defaults in making such redemption payment, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the Redemption Date; 

(7) the CUSIP, ISIN or other similar numbers, if any, printed on the Securities being redeemed; 

(8) that no representation is made as to the correctness or accuracy of the CUSIP, ISIN or other similar numbers, if any,
listed in such notice or printed on the Securities; and 
 (9) if the redemption or notice thereof is subject to
one or more conditions, a statement to such effect and the condition or conditions precedent. 
 (c) At the Company’s
request, the Trustee shall give the notice of redemption in the Company’s name and at the Company’s expense. In such event, the Company shall provide the Trustee with the information required by this Section 3.03(b).

 Section 3.04 Effect of Notice of Redemption 
 (a) Once notice of redemption is mailed to Holders, Securities (or portions thereof) called for redemption become irrevocably due and payable on the Redemption Date and at the Redemption Price. Upon
surrender to the Paying Agent, such Securities shall be paid at the Redemption Price, plus accrued and unpaid interest to the Redemption Date; provided that if the Redemption Date is after the taking of a record of the Holders on a record
date and on or prior to the related Interest Payment Date, the accrued and unpaid interest shall be payable to the Person in whose name the redeemed Securities are registered on such record date. Failure to give notice or any defect in the notice to
any Holder shall not affect the validity of the notice to any other Holder. 

  
 35 









 (b) Any redemption or notice of redemption may, at the Company’s discretion, be subject
to one or more conditions precedent and, in the case of a redemption with the net cash proceeds (other than Designated Proceeds) of an Equity Offering, notice may be given prior to, and subject to, the completion of the related Equity Offering.

 Section 3.05 Deposit of Redemption Price 
 No later than 10:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Paying Agent (or, if the Company or a Subsidiary is the Paying Agent, shall segregate and hold in
trust) money sufficient to pay the Redemption Price of and accrued and unpaid interest on all Securities to be redeemed on that date. If the Company complies with the provisions of this paragraph, then on and after the Redemption Date, interest will
cease to accrue on the Securities or the portions of Securities called for redemption. 
 Section 3.06 Securities Redeemed in Part

 Upon cancellation of a Security that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the
Holder (at the Company’s expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered. The Trustee shall notify the Registrar of the issuance of such new Security. 

Section 3.07 Optional Redemption 
 (a) On or after March 1, 2016, the Company may redeem all or a part of the Securities at any time and from time to time at its option at the following Redemption Prices (expressed as percentages of

any, thereon to the Redemption Date, with the net cash proceeds (other than Designated Proceeds) of any one or more Equity Offerings; provided, that (i) at least 65% of the aggregate principal amount of the Securities (including any
Additional Securities) issued under this Supplemental Indenture remains outstanding immediately after each such redemption and (ii) each such redemption occurs within 180 days of the date of the closing of the related Equity Offering.

 (1) 100% of the principal amount thereof, plus


  
 36

(3) accrued and unpaid interest, if any, thereon to the Redemption Date. 

The Company shall notify the Trustee of the Applicable Premium by delivering to the Trustee, on or before the applicable Redemption Date, an
Officers’ Certificate showing the calculation thereof in reasonable detail, and the Trustee shall have no responsibility for such calculation. 
 (d) If Holders of not less than 95% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the Company, or any
third party making a Change of Control Offer in lieu of the Company as permitted by Section 4.12, purchases all of the Securities validly tendered and not withdrawn by such Holders, the Company or such third party will have the right,
upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer, to redeem all Securities that remain outstanding following such purchase at a Redemption
Price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of Control Payment, accrued and unpaid interest thereon to the Redemption Date. 

(e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through
3.06 hereof. 
 (f) The Securities will not be redeemable at the option of the Company except as set forth in this

otherwise violate the terms of this Supplemental Indenture.

 Section 4.02 Reports 
 (a) Whether or not required by the Commission’s rules and regulations, so long as any Securities are outstanding, the Company will furnish to the Trustee and each Holder of Securities, within the
time periods specified in the Commission’s rules and regulations: 
 (1) all quarterly and annual reports
that would be required to be filed with the Commission on Forms 10-Q and 10-K if the Company were required to file such reports; and 
 (2) all current reports that would be required to be filed with the Commission on Form 8-K if the Company were required to file such reports. 
 The Company will be deemed to have furnished such reports to the Trustee and the Holders of Securities if it has filed such reports with the Commission using the EDGAR filing system and such reports are
publicly available and has notified the Trustee, in writing, that such reports are currently available. 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. In addition, the Company will file a copy of each of the reports referred to in clauses
(1) and (2) of this Section 4.02(a) with the Commission for public availability within the time periods specified in the rules and regulations applicable to such reports (unless the Commission will not accept such a filing) and make
such information available to securities analysts and prospective investors upon request. 
 (b) 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 clauses (1) and (2) of Section 4.02(a), with the Commission
within the time periods specified above unless the Commission will not accept such a filing. The Company agrees that it will not take any action for the purpose of causing the Commission not to accept any such filings. If, notwithstanding the
preceding, the Commission will not accept the Company’s filings for any reason, the Company will post the reports referred to in Section 4.02(a) on its website within the time periods that would apply if the Company were required to
file those reports with the Commission. 
 (c) In addition, the Company and the Guarantors agree that, for so long as any
Securities remain outstanding, if at any time the Company is not required to file with the SEC the reports required by Sections 4.02(a) and (b), they will furnish to Holders of Securities and to prospective investors, upon their
request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act. 
 (d) The Company and
the Guarantors shall also comply with Section 314(a) of the TIA. 
 (e) Delivery of such reports, information and documents
to the Trustee shall be for informational purposes only and the Trustee’s receipt of such shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including our compliance
with any of the covenants contained in the Indenture (as to which the Trustee will be entitled to conclusively rely upon an Officer’s Certificate.) 
 Section 4.03 Incurrence of Indebtedness and Issuance of Disqualified Stock 
 (a) 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”) any Indebtedness (including Acquired 

  
 38 









 
Debt), other than Permitted Debt, and the Company shall not issue, and shall not permit any of its Restricted Subsidiaries to issue, any Disqualified Stock; provided, however, that the
Company or any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) or issue shares of Disqualified Stock if the Company’s 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 is issued would have been at least 2 to 1, determined on a pro forma basis (including a pro
forma application of the net proceeds therefrom), as if such additional Indebtedness had been incurred, or such Disqualified Stock had been issued, as the case may be, at the beginning of such four-quarter period. 

(b) The provisions of Section 4.03(a) shall not apply to the incurrence of any of the following items of Indebtedness
(collectively, “Permitted Debt”): 
 (1) the incurrence by the Company or any Restricted Subsidiary of
Indebtedness pursuant to one or more Credit Facilities; provided, however, that, immediately after giving effect to any such incurrence, the aggregate principal amount (or accreted value, as applicable) of all Indebtedness incurred under this
clause (1) and then outstanding does not exceed the greater of (A) $500 million and (B) 35% of Consolidated Tangible Assets at the time of incurrence; 

(2) the incurrence by the Company and the Guarantors of Indebtedness represented by the Initial Securities and the
Subsidiary Guarantees issued on the Issue Date; 
 (3) the incurrence by the Company or any of its Restricted
Subsidiaries of Existing Indebtedness; 
 (4) the incurrence by the Company or any of its Restricted Subsidiaries
of Permitted Refinancing Indebtedness, the net proceeds of which are applied to refinance any Indebtedness incurred in respect of any Indebtedness described under clauses (2), (3), (4), (8) or (11) of this paragraph or incurred pursuant to
Section 4.03(a); 
 (5) the incurrence by the Company or any of its Restricted Subsidiaries of
intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries; provided, however, that (A) if the Company or any Guarantor is the obligor and a Restricted Subsidiary of the Company that is not a Guarantor
is the obligee on such Indebtedness, such Indebtedness will be subordinated to the payment in full of all Obligations with respect to the Securities and the Subsidiary Guarantees, as the case may be, 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 of the Company and (ii) any sale or other transfer of any such Indebtedness to a Person that is not
either the Company or a Restricted Subsidiary of the Company shall 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 is not then permitted by this clause
(5); 
 (6) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness represented by
Capital Lease Obligations, mortgage financings or purchase money obligations (including any Acquired Debt), in each case, incurred in connection with the purchase of, or for the purpose of financing the purchase of, the cost of construction,
improvement or development of, property, plant or equipment used in the Permitted Business of the Company or a Restricted Subsidiary of the Company or incurred to extend, refinance, renew, replace, defease or refund any such purchase price or cost
of construction, improvement or development, in an aggregate principal amount not to exceed $50 million at any time outstanding; 

  
 39 









 (7) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness consisting of Hedging Obligations entered into in the ordinary course of business and not for speculative purposes; 
 (8) the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness arising from agreements of the Company or any of its Restricted Subsidiaries providing for indemnification,
adjustment of purchase price or similar obligations, in each case, incurred in connection with the disposition or acquisition of any business, assets or a Restricted Subsidiary of the Company or any business or assets of its Restricted Subsidiaries,
other than guarantees of Indebtedness incurred by any Person acquiring all or any portion of such business, assets or a Restricted Subsidiary of the Company or any of its Restricted Subsidiaries for the purposes of financing such acquisition;
provided, however, that (A) such Indebtedness is not reflected on the balance sheet of the Company or any of its Restricted Subsidiaries (contingent obligations referred to in a footnote to financial statements and not otherwise
reflected on the balance sheet will not be deemed to be reflected on such balance sheet for purposes of this clause (A)) and (B) the maximum liability in respect of all such Indebtedness incurred in connection with a disposition shall at no
time exceed the gross proceeds including noncash proceeds (the Fair Market Value of such noncash proceeds being measured at the time received and without giving effect to any subsequent changes in value) actually received by the Company and its
Restricted Subsidiaries in connection with such disposition; 
 (9) the guarantee by the Company or any
Restricted Subsidiary of Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted to be incurred by any other provision of this Section 4.03; provided that the guarantee of any Indebtedness of a
Restricted Subsidiary of the Company that ceases to be such a Restricted Subsidiary shall be deemed a Restricted Investment at the time such Restricted Subsidiary’s status terminates in an amount equal to the maximum principal amount so
guaranteed, for so long as, and to the extent that, such guarantee remains outstanding; 
 (10) the issuance by a
Restricted Subsidiary of the Company of Disqualified Stock to the Company or to any of its Restricted Subsidiaries; provided, however, that any subsequent event or issuance or transfer of any Equity Interests that results in the owner
of such Disqualified Stock ceasing to be the Company or any of its Restricted Subsidiaries or any subsequent transfer of such preferred stock to a Person, other than the Company or one of its Restricted Subsidiaries, shall be deemed to be an
issuance of Disqualified Stock by such Subsidiary that was not permitted by this clause (10); 
 (11) the
incurrence by the Company or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness; 
 (12)
the incurrence by the Company or any of its Restricted Subsidiaries of Indebtedness incurred in the ordinary course of business under (A) documentary letters of credit, or surety bonds or insurance contracts, which are to be repaid in full not
more than one year after the date on which such Indebtedness is originally incurred to finance the purchase of goods by the Company or a Restricted Subsidiary of the Company, (B) standby letters of credit, surety bonds or insurance contracts
issued for the purpose of supporting (i) workers’ compensation or similar liabilities of the Company or any of its Restricted Subsidiaries or (ii) performance, payment, deposit or surety obligations of the Company or any of its
Restricted Subsidiaries and (C) bid, advance payment and performance bonds and surety bonds or similar insurance contracts for the Company and its Restricted Subsidiaries, and refinancings thereof; and 

  
 40 









 (13) the incurrence by the Company or any of its Restricted Subsidiaries of
Indebtedness (in addition to Indebtedness permitted by any other provision of this covenant) in an aggregate principal amount (or accreted value, as applicable) not to exceed the greater of (A) $50 million at any one time outstanding and
(B) 3.5% of Consolidated Tangible Assets as of any date of incurrence after giving pro forma effect to such incurrence and the application of proceeds therefrom. 
 (c) To the extent the Company’s Unrestricted Subsidiaries incur Non-Recourse Indebtedness and any such Indebtedness ceases to be Non-Recourse Indebtedness of such Unrestricted Subsidiary, then such
event shall be deemed to constitute an incurrence of Indebtedness by a Restricted Subsidiary of the Company that was subject to this covenant. 
 (d) Neither the Company nor any Guarantor will incur any Indebtedness (including Permitted Debt) that is contractually subordinated in right of payment to any other Indebtedness of the Company or such
Guarantor, as the case may be, unless such Indebtedness is also contractually subordinated in right of payment to the Securities or the Subsidiary Guarantees, as the case may be, on substantially identical terms; provided, however, that no
Indebtedness of any Person will be deemed to be contractually subordinated in right of payment to any other Indebtedness of such Person solely by virtue of being unsecured. 
 (e) For purposes of determining compliance with this Section 4.03, in the event that an item of proposed Indebtedness (including Acquired Debt) meets the criteria of more than one of the
categories of Permitted Debt set forth in Section 4.03(b) or is entitled to be incurred pursuant to Section 4.03(a), the Company will, in its sole discretion, classify (or later classify or reclassify) in whole or in part
such item of Indebtedness in any manner that complies with this Section 4.03 and such item of Indebtedness or a portion thereof may be classified (or later classified or reclassified) in whole or in part as having been incurred under
more than one of the applicable clauses of Section 4.03(b) or pursuant to Section 4.03(a). Accrual of interest, the accretion of accreted value and the payment of interest in the form of additional Indebtedness will not be
deemed to be an incurrence of Indebtedness for purposes of this Section 4.03. 
 (f) 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-dominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S.
dollar-dominated 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 covenant, the maximum amount of Indebtedness that the Company may incur pursuant to this covenant 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, 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.

forth in Section 4.03(a); and

 (ii) 100% of the aggregate
net cash proceeds (other than Designated Proceeds), or the Fair Market Value of assets or property other than cash, received by the Company from the issue or sale, in either case, since the Issue Date of (I) Equity Interests of the Company

transfers and distributions of cash, assets or other property, in an amount not to exceed the aggregate amount of such Restricted Investment. 
 (b) The provisions of Section 4.04(a) shall not prohibit: 
 (1) the payment of any dividend or the consummation of an irrevocable redemption of Subordinated Obligations within 60 days after the date of the declaration of such dividend or the delivery of the
irrevocable notice of redemption, as the case may be, if at the date of the declaration or the date on which such irrevocable notice is delivered, such dividend or redemption would have complied with the provisions of this Supplemental Indenture;

 (2) the making of any Restricted Payments described in clause (2) or (3) of

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, assume or
suffer to exist any Lien (other than Permitted Liens) upon any of its property or assets (including Capital Stock of a Restricted Subsidiary), whether owned on the Issue Date or acquired after that date, securing any Indebtedness, unless:

 (1) in the case of Liens securing Subordinated Obligations of the Company or a Restricted Subsidiary, the
Securities or Subsidiary Guarantees, as applicable, are contemporaneously secured by a Lien on such property or assets on a senior basis to the Subordinated Obligations so secured with the same priority that the Securities or Subsidiary Guarantees,
as applicable, have to such Subordinated Obligations until such time as such Subordinated Obligations are no longer so secured by a Lien; and 
 (2) in the case of Liens securing Senior Indebtedness of the Company or a Restricted Subsidiary, the Securities or Subsidiary Guarantees, as applicable, are contemporaneously secured by a Lien on such
property or assets on an equal and ratable basis with the Senior Indebtedness so secured until such time as such Senior Indebtedness is no longer so secured by a Lien. 
 (b) Upon the occurrence of an Investment Grade Rating Event but not before then, the covenant set forth in Section 4.05(c) shall become effective and shall apply to the Company and its
Subsidiaries. 
 (c) Upon the occurrence and at all times after an Investment Grade Ratings Event, if the Company or any
Subsidiary incurs any Indebtedness secured by a Lien (other than Permitted Liens of the types described in clause (2), (5), (6), (7), (8), (9), (10), (11), (13), (14), (15), (16) or (17) of the definition of the term “Permitted
Liens” in Section 1.01) on any asset, whether now owned or hereafter acquired, or if any Subsidiary that is not a Guarantor of the Securities incurs any Indebtedness of any kind, the Company or such Subsidiary, as the case may be,
will secure the Securities equally and ratably with (or, at its option, prior to) the Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien, or will guarantee the Securities on a full and unconditional senior
basis (if a Subsidiary 

  
 45 









 
incurs unsecured Indebtedness), in each case unless the aggregate amount of all Indebtedness secured by a Lien and the Attributable Amounts of all Sale/Leaseback Transactions would not exceed
12.5% of Consolidated Tangible Assets. 
 Section 4.06 Dividend and Other Payment Restrictions Affecting Subsidiaries 

(a) The Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or otherwise cause or
suffer to exist or become effective any encumbrance or restriction on the ability of any Restricted Subsidiary of the Company to: 
 (1) (x) pay dividends or make any other distributions to the Company or any of its Restricted Subsidiaries on its Capital Stock or (y) pay any Indebtedness owed to the Company or any of its
Restricted Subsidiaries; provided, that the priority of any preferred stock in receiving dividends or liquidating distributions prior to the payment of dividends or liquidating distributions on common stock shall not be deemed to be a
restriction on the ability to make distributions on Capital Stock; 
 (2) make loans or advances to the Company
or any of its Restricted Subsidiaries; or 
 (3) transfer any of its properties or assets to the Company or any
of its Restricted Subsidiaries. 
 (b) However, the restrictions in Section 4.06(a) will not apply to encumbrances
or restrictions existing under or by reason of: 
 (1) any Credit Facility in effect after the Issue Date to the
extent its provisions, taken as a whole, are no more restrictive with respect to such dividend, distribution or other payment restrictions and loan or investment restrictions than those contained in the Credit Facilities as in effect on the Issue
Date; 
 (2) (i) this Supplemental Indenture, the Securities or the Subsidiary Guarantees, (ii) the Existing
Indenture, the Existing Notes or the Existing Guarantees or (iii) any other indentures governing debt securities issued by the Company or any Guarantor that are no more restrictive with respect to such dividend, distribution or other payment
restrictions and loan or investment restrictions than those contained in this Supplemental Indenture, the Securities and the Subsidiary Guarantees; 
 (3) any future Liens that may be permitted to be granted under, or incurred not in violation of, any other provisions of this Supplemental Indenture; 

(4) applicable law or any applicable rule, regulation or order; 

(5) any instrument governing Indebtedness or Capital Stock, or any other agreement relating to any property or assets, of
a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time 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 or such Person’s subsidiaries, so acquired, provided, that, in the case of Indebtedness, such Indebtedness was permitted by the terms of this Supplemental Indenture to be incurred; 

  
 46 









 (6) restrictions of the nature described in Section 4.06(a)(3)
by reason of customary non-assignment provisions in contracts, agreements, licenses and leases entered into in the ordinary course of business;

 Section 4.07 Asset Sales 
 (a) 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 the Asset Sale at least equal to the Fair Market Value (which shall give effect to the assumption by another Person of any liabilities as provided for in clause
(2)(A) of this paragraph and which, in the case of an Asset Sale involving consideration not exceeding $100 million, need not be determined by the Board of Directors) of the assets or Equity Interests issued or sold or otherwise disposed of;
and 
 (2) (x) at least 75% of the consideration received in such Asset Sale is in the form of cash or Cash
Equivalents or (y) the Fair Market Value of all forms of consideration other than cash or Cash Equivalents received for all Asset Sales since the Issue Date does not exceed in the 

  
 47 









 
aggregate 10% of Consolidated Net Worth of the Company at the time each determination is made; provided that any of the following items shall be deemed to be cash and Cash Equivalents for
the purposes of this clause (2): 
 (A) the assumption of any liabilities (as shown on the Company’s or the
Restricted Subsidiary’s most recent balance sheet) of the Company or any Restricted Subsidiary of the Company (other than liabilities that are by their terms subordinated to Securities issued under this Supplemental Indenture or any Subsidiary
Guarantee) by the transferee of any such assets pursuant to a customary novation agreement that releases the Company or the Restricted Subsidiary from further liability; 

(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 the Restricted Subsidiary into cash or Cash Equivalents within 180 days following their receipt (to the extent of cash or Cash Equivalents received); 

(C) other assets or rights used or useful in a Permitted Business, including, without limitation, assets or Investments of
the nature or type described in clause (13) of the definition of “Permitted Investments” in Section 1.01; and 
 (D) accounts receivable of a business retained by the Company or any of its Restricted Subsidiaries following the sale of such business; provided, that such accounts receivable are not
(i) past due more than 60 days and (ii) do not have a payment date greater than 90 days from the date of the invoice creating such accounts receivable; 
 provided, that any Asset Sale pursuant to a condemnation, appropriation or other similar taking, including by deed in lieu of condemnation, or pursuant to the foreclosure or other enforcement of a
Lien incurred not in violation of Section 4.05 or exercise by the related lienholder of rights with respect thereto, including by deed or assignment in lieu of foreclosure, shall not be required to satisfy the conditions set forth in
clauses (1) and (2) of this paragraph. 
 (b) Within 365 days after the receipt of any Net Proceeds from an Asset
Sale, the Company or the Restricted Subsidiary, as the case may be, may apply such Net Proceeds, at its option: 

(1) to prepay, repay, purchase, repurchase or redeem any Senior Indebtedness of the Company or any Restricted Subsidiary
of the Company; 
 (2) to acquire a controlling interest in another business or all or substantially all of the
assets or operating line of another business, in each case engaged in a Permitted Business; 
 (3) to make
capital expenditures; or 
 (4) to acquire other non-current assets to be used in a Permitted Business,
including, without limitation, assets or Investments of the nature or type described in clause (13) of the definition of “Permitted Investments” in Section 1.01; 
 provided that the Company or the applicable Restricted Subsidiary will be deemed to have complied with clause (2) or (3) of this Section 4.07(b) if, within 365 days of such
Asset Sale, the Company or such Restricted Subsidiary shall have commenced and not completed or abandoned an expenditure or Investment, or entered into a binding agreement with respect to an expenditure or Investment, in compliance with such clause
(2) or (3), and that expenditure or Investment is substantially completed 

  
 48 









 
within a date one year and six months after the date of such Asset Sale. Pending the final application of any such Net Proceeds, the Company may temporarily reduce Indebtedness under any Credit
Facility or otherwise expend or invest such Net Proceeds in any manner that is not prohibited by this Supplemental Indenture. Any Net Proceeds from Asset Sales described in this paragraph that are not applied or invested as provided in the first
sentence of this paragraph shall be deemed to constitute “Excess Asset Sale Proceeds.” 
 (c) When the aggregate
amount of Excess Asset Sale Proceeds exceeds $30 million, the Company shall make an offer to the Holders of Securities and the holders of any other Senior Indebtedness that is subject to requirements with respect to the application of net proceeds
from asset sales that are substantially similar to those contained in this Section 4.07 (an “Asset Sale Offer”) to purchase on a pro rata basis (with the Excess Asset Sale Proceeds prorated between the Holders of the Securities
and such holders of such other Senior Indebtedness based upon outstanding aggregate principal amounts) the maximum principal amount of the Securities and such other Senior Indebtedness that may be purchased or prepaid, as applicable, out of the
prorated Excess Asset Sale Proceeds, at an offer price in cash in an amount equal to 100% of the principal amount thereof (or accreted amount in the case of any Senior Indebtedness issued with original issue discount) plus accrued and unpaid
interest thereon to the date of purchase (the “Asset Sale Payment”), in accordance with the procedures set forth in this Section 4.07. To the extent that the aggregate principal amount of Securities and other Senior
Indebtedness tendered (and electing to be redeemed or repaid, as applicable) pursuant to an Asset Sale Offer is less than the Excess Asset Sale Proceeds, the Company and its Restricted Subsidiaries may use any remaining Excess Asset Sale Proceeds
for general corporate purposes and any other purpose not prohibited by this Supplemental Indenture. If the aggregate principal amount of the Securities and such other Senior Indebtedness surrendered by holders thereof exceeds the amount of the
prorated Excess Asset Sale Proceeds, the Company shall select the Securities and such other Senior Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer, the amount of Excess Asset Sale Proceeds shall be reset at
zero. 
 (d) When the Company becomes obligated to make an Asset Sale Offer, the Company will mail a notice to each Holder
describing the transaction or transactions that constitute the Asset Sale and offering to repurchase Securities on the date (the “Asset Sale Payment Date”) specified in such notice, which date will be no earlier than 30 days nor later than
60 days from the date such notice is mailed, pursuant to the procedures required by this Supplemental Indenture and described in such notice. 
 (e) On the Asset Sale Payment Date, the Company will, to the extent lawful: 
 (1) accept for payment all Securities or portions thereof properly tendered pursuant to the Asset Sale Offer, subject to proration based on the amount of Excess Asset Sale Proceeds pursuant to clause
(c) above of this Section 4.07; 
 (2) deposit with the Paying Agent an amount equal to the
amount of Excess Asset Sale Proceeds that, after giving effect to proration with holders of other Senior Indebtedness pursuant to clause (c) above of this Section 4.07, is allocable to the Securities or portions thereof so tendered
(or, if less, the aggregate Asset Sale Payment for all Securities validly tendered and not withdrawn); and 
 (3)
deliver or cause to be delivered to the Trustee the Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. 

  
 49 









 (f) The Paying Agent will promptly mail (or cause to be transferred through the facilities
of the Depositary) to each Holder of Securities so tendered and not withdrawn and accepted for payment in accordance with this Section 4.07, the Asset Sale Payment for such tendered Securities, and the Trustee will promptly authenticate
and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any, by such Holder; provided that each such new Security will be in a
minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. 
 (g) If the Asset Sale Payment Date is
on or after an interest payment 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 purchased Security is registered on such record date, and no other interest
will be payable to Holders who tender Securities pursuant to the Asset Sale Offer. 
 (h) The Company will publicly announce the
results of the Asset Sale Offer on or as soon as practicable after the date such Asset Sale Offer is completed. 
 (i) The
Company will comply with the requirements of Rule 14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with an Asset Sale Offer. To the extent that
the provisions of any securities laws or regulations conflict with the provisions of this Section 4.07, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations
under this Section 4.07 by virtue of the Company’s compliance with such securities laws or regulations. 
 Section 4.08
Transactions with Affiliates 
 (a) The Company will not, and will not permit any of its Restricted Subsidiaries to,
directly or indirectly, make any payment to, or sell, lease, transfer or otherwise dispose of any 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 any such Person (each of the foregoing, an “Affiliate Transaction”) if such Affiliate Transaction involves aggregate consideration in excess of $1 million, unless:

 (1) such Affiliate Transaction is on terms that are no less favorable to the Company or the relevant
Restricted Subsidiary than those that could have been obtained in a transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if no comparable transaction is available with which to compare such Affiliate Transaction,
such Affiliate Transaction is otherwise fair to the Company or the relevant Restricted Subsidiary from a financial point of view, evidenced (if required by Section 4.08(a)(2)) by the Officers’ Certificate provided for in
Section 4.08(a)(2); and 
 (2) the Company delivers to the Trustee: 

(A) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of at least $20 million but equal to or less than $40 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with Section 4.08(a)(1); and 

(B) with respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate
consideration in excess of $40 million, a resolution of its Board of Directors set forth in an Officers’ Certificate certifying that such Affiliate Transaction complies with Section 4.08(a)(1) and that such Affiliate Transaction has
been approved by a majority of the disinterested members of its Board of Directors; 

  
 50 









 (b) None of the following shall be deemed to be Affiliate Transactions and therefore shall
not be subject to the provisions of Section 4.08(a): 
 (1) any employment, equity award, equity
option or equity appreciation agreement or plan, agreement or other similar compensation plan or arrangement entered into by the Company or any of its Restricted Subsidiaries in the ordinary course of its business; 

(2) transactions between or among (A) the Company and one or more Restricted Subsidiaries and (B) any Restricted
Subsidiaries; 
 (3) the performance of any written agreement in effect on the Issue Date, as such agreement may
be amended, modified or supplemented from time to time; provided, however, that any amendment, modification or supplement entered into after the Issue Date will be permitted only to the extent that its terms do not adversely affect the
rights of any Holders of the Securities (as determined in good faith by an Officer of the Company, and, if such amendment, modification or supplement involves aggregate consideration in excess of $40 million, as determined in good faith by the Board
of Directors) as compared to the terms of the agreement in effect on the Issue Date; 
 (4) loans or advances to
officers, directors and employees for moving, entertainment and travel expenses, drawing accounts and similar expenditures and other purposes, in each case, in the ordinary course of business; 

(5) maintenance in the ordinary course of business of customary benefit programs or arrangements for employees, officers
or directors, including vacation plans, health and life insurance plans, deferred compensation plans and retirement or savings plans and similar plans; 
 (6) fees and compensation paid to, and indemnity provided on behalf of, officers, directors, employees or consultants of the Company or any of its Restricted Subsidiaries in their capacity as such, to the
extent such fees and compensation are reasonable and customary; 
 (7) sales of Equity Interests of the Company
(other than Disqualified Stock) to Affiliates of the Company or any of its Restricted Subsidiaries; 
 (8)
Restricted Payments that are permitted by Section 4.04; and 
 (9) any transactions between the
Company or any Restricted Subsidiary and any Person, a director of which is also a director of the Company or a Restricted Subsidiary; provided that such director abstains from voting as a director of the Company or the Restricted Subsidiary,
as applicable, in connection with the approval of the transaction. 
 Section 4.09 Designation of Restricted and Unrestricted
Subsidiaries 
 (a) The Board of Directors may designate any Unrestricted Subsidiary to be a Restricted Subsidiary only if:

 (1) immediately after giving effect to such designation, the Company could incur at least $1.00 of additional
Indebtedness pursuant to the Fixed Charge Coverage Ratio test under Section 4.03(a) or the Fixed Charge Coverage Ratio of the Company immediately after giving effect to such designation would not be less than the Fixed Charge Coverage
Ratio of the Company immediately prior to such designation; 

  
 51 









 (2) immediately before and immediately after giving effect to such
designation, no Default or Event of Default shall have occurred and be continuing; and 
 (3) the Company
certifies that such designation complies with this Section 4.09. Any such designation by the Board of Directors shall be evidenced by the Company promptly filing with the Trustee a copy of the resolution giving effect to such designation
and an Officers’ Certificate certifying that such designation complied with the preceding provisions. 
 (b) The Board of
Directors may designate any Subsidiary of the Company to be an Unrestricted Subsidiary under the circumstances and pursuant to the requirements described in the definition of “Unrestricted Subsidiary” set forth in Section 1.01.
For purposes of making the determination as to whether such designation would be made in compliance with this Section, all outstanding Investments by the Company and its Restricted Subsidiaries (except to the extent repaid in cash) in the Subsidiary
so designated will be deemed to be Restricted Payments at the time of such designation and will reduce the amount available for Restricted Payments under Section 4.04(a). All such outstanding Investments will be deemed to constitute
Investments in an amount equal to the greater of (1) the net book value (determined in accordance with GAAP) of such Investments at the time of such designation and (2) the Fair Market Value of such Investments at the time of such
designation. 
 Section 4.10 Additional Subsidiary Guarantees 

If, after the Issue Date, any Restricted Subsidiary (other than a Foreign Subsidiary) of the Company that is not already a Guarantor
(whether or not acquired or created by the Company or another Restricted Subsidiary after the Issue Date) incurs any Indebtedness, or guarantees any other Indebtedness of the Company or a Guarantor, in either case in excess of a De Minimis Amount,
then the Company shall cause such Restricted Subsidiary to become a Guarantor by executing a supplemental indenture substantially in the form of Exhibit C hereto and delivering it to the Trustee within 180 days of the date on which it
incurred or guaranteed such Indebtedness, as the case may be. 
 Section 4.11 [Intentionally
Omitted.] 
 Section 4.12 Change of Control 

(a) If a Change of Control occurs, each Holder of Securities 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 thereof) of that Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”) at an offer price in cash equal to 101% of the aggregate principal
amount thereof plus accrued and unpaid interest thereon to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control, the Company will mail to each Holder of Securities a notice describing the
transaction or transactions that constitute the Change of Control and offering to repurchase the Securities on the date specified in such notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is

Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all
Securities or portions thereof so tendered; and

Securities so accepted together with an Officers’ Certificate stating the aggregate principal amount of Securities or portions thereof being purchased by the Company. 
 (c) The Paying Agent will promptly mail (or cause to be transferred through the facilities of the Depositary) to each Holder of Securities so tendered and not withdrawn the Change of Control Payment for
such tendered Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased portion of the Securities surrendered, if any, by
such Holder; provided that each such new Security will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Trustee will notify the Registrar of the issuance of the new Security. 

(d) If the Change of Control Payment Date is on or after an interest payment 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 Security is registered at the close of business on such record date, and no other interest will be payable to Holders who tender pursuant to the Change of Control
Offer. 
 (e) 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. 
 (f) The provisions described above in this Section 4.12 that require the
Company to make a Change of Control Offer following a Change of Control will be applicable regardless of whether or not any other provisions of this Supplemental Indenture are applicable. 

(g) The Company will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section applicable to a Change of Control Offer made by the Company and purchases all Securities validly tendered and not withdrawn under
such Change of Control Offer. A Change of Control Offer may be made with respect to the Securities in advance of a Change of Control, and conditional upon the occurrence of such Change of Control, if a definitive agreement for the Change of Control
is in place at the time of making the Change of Control Offer. 
 (h) The Company will comply with the requirements of Rule
14e-l under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control. To the extent that
the provisions of any securities laws or regulations conflict with the provisions of this Section 4.12, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations
under this Section 4.12 by virtue of the Company’s compliance with such securities laws or regulations.

 Section 4.13 Maintenance of Office or Agency for Registration of Transfer, Exchange and Payment of
Securities 
 So long as any of the Securities shall remain outstanding, the Company will, in accordance with
Section 2.03 hereof, maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, or the Registrar) in the continental United States where the Securities may be surrendered for exchange or
registration of transfer as provided in this Supplemental Indenture, where notices and demands to or upon the Company in respect to the Securities may be served, and where the Securities may be presented or surrendered for payment. The Company may
also from time to time designate one or more other offices or agencies in the continental United States where Securities may be presented or surrendered for any and 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 under Section 2.03 to maintain an office or agency in New York, New York where any Definitive Securities may be presented or
surrendered for payment. The Company will give to Trustee prompt written notice of the location of any such office or agency and of any change of location thereof. In case the Company shall fail to maintain any such office or agency or shall fail to
give such notice of the location or of any change in the location thereof, such surrenders, presentations and demands may be made and notices may be served at the designated Corporate Trust Office of the Trustee, and the Company hereby appoints the
Trustee its agent to receive at the aforesaid office all such surrenders, presentations, notices and demands.

by it; and 
 (4) that it will acknowledge, accept and agree to comply in all aspects with the provisions of this
Supplemental Indenture relating to the duties, rights and liabilities of such Paying Agent. 
 (b) If the Company shall not act

premium, if any, or interest so becoming due, such sum to be held in trust for the benefit of the Holders of Securities entitled to such principal of or premium, if any, or interest, and (unless such Paying Agent is the Trustee) the Company will
promptly notify the Trustee of its failure so to act.

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, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the

Fixed Charge Coverage Ratio of the Company immediately prior to such transaction; 
 (B) immediately after giving

 Section 6.01 Events of Default 

(a) Each of the following is an “Event of Default”: 

(1) default for 30 days in the payment when due of interest on the Securities; 

(2) default in the payment when due of the principal of, or premium, if any, on the Securities; 

(3) failure by the Company or any of its Restricted Subsidiaries to comply with Section 4.12 or 5.01
hereof for 30 days after receipt of written notice specified in Section 6.01(b); 
 (4) failure by
the Company or any of its Restricted Subsidiaries for 60 days after receipt of written notice specified in Section 6.01(b) to comply with any of its other agreements contained in this Supplemental Indenture or the Securities (other than

 57 









 (5) 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 of its Restricted Subsidiaries (or the payment of which is guaranteed by the Company or any of its Restricted Subsidiaries),
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 premium, if any, or interest on such Indebtedness prior to the expiration of the grace period provided in such Indebtedness (a “Payment Default”); or 

(B) results in the acceleration of such Indebtedness prior to its express 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 without duplication $30 million or more; 
 (6) failure by the Company or any of its Restricted Subsidiaries to pay final judgments aggregating in excess of $30 million (excluding amounts covered by insurance), which judgments are not paid,
discharged or stayed for a period of 60 days; 
 (7) except as permitted by this Supplemental Indenture, any
Subsidiary Guarantee of a Guarantor shall be held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or
disaffirm its obligations under its Subsidiary Guarantee; and 
 (8) (A) the Company or a Significant Subsidiary
or a group of Subsidiaries that, taken together, would constitute a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law: 
 (i) commences a voluntary case or proceeding; 
 (ii) consents to
the entry of an order for relief against it in an involuntary case or proceeding in which it is a debtor; 

(iii) consents to the appointment of a Custodian of it or for any substantial part of its property; 

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

(v) consents to the institution of a bankruptcy or an insolvency proceeding against it; 

or takes any comparable action under any foreign laws relating to insolvency; or 

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

(i) is for relief against the Company or any Significant Subsidiary or a group of Subsidiaries that, taken together,
would constitute a Significant Subsidiary in an involuntary case in which it is a debtor; 

  
 58 









 (ii) appoints a Custodian of the Company or any Significant Subsidiary or a
group of Subsidiaries that, taken together, would constitute a Significant Subsidiary or for any substantial part of its property; or 
 (iii) orders the winding up or liquidation of the Company or any Significant Subsidiary or a group of Subsidiaries that, taken together would constitute a Significant Subsidiary; 

or any similar relief is granted under any foreign laws and the order, decree or relief remains unstayed and in effect for
60 consecutive days. 
 (b) However, a Default under clauses (3) and (4) of Section 6.01(a) will not
constitute an Event of Default until the Trustee or the Holders of at least 25% in principal amount of the outstanding Securities notify the Company of the Default and the Company does not cure such Default within the time specified in clauses
(3) and (4) of Section 6.01(a) after receipt of such notice. Such notice must specify the Default, demand that it be remedied and state that such notice is a “Notice of Default.” 

(c) Whether or not a group of Subsidiaries would constitute, when taken together, a Significant Subsidiary will be determined, for
purposes of Section 6.01(a), on the basis of the latest available consolidated financial statements of the Company and its Subsidiaries. 
 Section 6.02 Acceleration of Maturity; Rescission and Annulment 
 (a)
If an Event of Default (other than an Event of Default described in clause (8) of Section 6.01(a)) occurs and is continuing, the Trustee by notice to the Company, or the Holders of at least 25% in principal amount of the outstanding
Securities by notice to the Company and the Trustee, may declare the principal of, premium, if any, and accrued and unpaid interest on all the Securities to be due and payable. Upon such a declaration, such principal, premium and accrued and unpaid
interest will be due and payable immediately. If an Event of Default described in clause (8) of Section 6.01(a) occurs and is continuing, the principal of, premium, if any, and accrued and unpaid interest on all the Securities will
become and be immediately due and payable without any further action or notice on the part of the Trustee or any Holders. The Holders of a majority in outstanding principal amount of the Securities by notice to the Trustee may on behalf of the
Holders of all the Securities rescind any such acceleration with respect to the Securities and its consequences if (1) rescission would not conflict with any judgment or decree of a court of competent jurisdiction, (2) all existing Events
of Default, other than the nonpayment of the principal of, premium, if any, and interest on the Securities that have become due solely by such declaration of acceleration, have been cured or waived and (3) there has been paid or deposited with
the Trustee a sum sufficient to pay all amounts due to the Trustee, its agents and its counsel incurred in connection with such Default or Event of Default. 
 (b) In the case of an Event of Default specified in clause (5) of Section 6.01(a), such Event of Default and all consequences thereof (excluding, however, any resulting payment default)
will be annulled, waived and rescinded with respect to the Securities, automatically and without any action by the Trustee or the Holders of the Securities, if within 60 days after such Event of Default first arose the Company delivers an
Officers’ Certificate to the Trustee stating that (1) the Indebtedness or guarantee that is the basis for such Event of Default has been paid or discharged, (2) the holders of the Indebtedness have rescinded or waived the acceleration
giving rise to such Event of Default or (3) the default that is the basis for such Event of Default has been otherwise cured; provided, however, that in no event shall an acceleration of the principal amount of the Securities
pursuant to Section 6.02(a) be annulled, waived or rescinded upon the happening of any such events. 

  
 59 









 Section 6.03 Other Remedies 

(a) If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of,
premium (if any), or interest on the Securities or to enforce the performance of any provision of the Securities or this Supplemental Indenture. 
 (b) The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in
exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are
cumulative to the extent permitted by law. 
 Section 6.04 Waiver of Past Defaults 

Subject to the last sentence of Section 6.02(a), the Holders of a majority in outstanding principal amount of the Securities,
by notice to the Trustee may on behalf of the Holders of all the Securities waive an existing Default or Event of Default and its consequences hereunder except a Default or Event of Default in the payment of the principal of, premium, if any, or
interest on a Security. When a Default or Event of Default is waived, it is deemed cured, but no such waiver shall extend to any subsequent or other Default or Event of Default or impair any consequent right. 

Section 6.05 Control by Majority 
 The Holders of a majority in outstanding principal amount of the Securities have the right to direct the time, method and place of conducting any proceeding for exercising any remedy available to the
Trustee or of exercising any trust or power conferred on the Trustee. However, the Trustee may refuse to follow any direction that conflicts with law or this Supplemental Indenture or, subject to Section 7.01 hereof, that the Trustee
determines is unduly prejudicial to the rights of other Holders or would involve the Trustee in personal liability; provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such
direction. Subject to Section 7.01, prior to taking any action hereunder, the Trustee shall be entitled to indemnification reasonably satisfactory to it against all loss, liability and expense caused by taking or not taking such action.

 Section 6.06 Limitation on Suits 
 (a) Except to enforce the right to receive payment of principal, premium (if any), or interest when due, a Holder may not pursue any remedy with respect to this Supplemental Indenture, the Securities or
the Subsidiary Guarantees unless: 
 (1) the Holder has previously given the Trustee written notice stating that
an Event of Default is continuing; 
 (2) Holders of at least 25% in outstanding principal amount of the
Securities have made a written request to the Trustee to pursue the remedy; 
 (3) such Holder or Holders have
furnished the Trustee reasonable security or indemnity against any loss, liability or expense; 
 (4) the Trustee
has not complied with the Holders’ request within 60 days after receipt of the request and the furnishing of security or indemnity; and 

  
 60 









 (5) the Holders of a majority in outstanding principal amount of the
Securities have not given the Trustee a direction that, in the opinion of the Trustee, is inconsistent with the request during such 60-day period. 
 (b) A Holder may not use this Supplemental Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder. 

Section 6.07 Rights of Holders to Receive Payment 
 Notwithstanding any other provision of this Supplemental Indenture, the right of any Holder to receive payment of principal of, premium, if any, and interest on the Securities held by such Holder, on or
after the respective due dates expressed in the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. 

Section 6.08 Collection Suit by Trustee 
 If an Event of Default specified in Section 6.01(a)(1) or Section 6.01(a)(2) hereof occurs and is continuing, the Trustee may recover judgment in its own name and as trustee of an
express trust against the Company or any Guarantor for the whole amount then due and owing (together with interest on any unpaid interest to the extent lawful) and the amounts provided for in Section 7.07 hereof to cover the costs and
expenses of collection, including the reasonable compensation, disbursement and advances of the Trustee, its agents and counsel. 

Section 6.09 Trustee May File Proofs of Claim 
 The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee and the Holders allowed in any judicial proceedings
relative to the Company or any Guarantor or their respective creditors or properties and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee in bankruptcy or other Person performing
similar functions, and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make 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 its counsel, and any other amounts due the Trustee under Section 7.07 hereof. 

Section 6.10 Priorities 
 (a) If the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money or property in the following order: 

First: costs and expenses of collection, including all sums paid or advanced by the Trustee hereunder and the
compensation, expenses and disbursements of the Trustee, its agents, and counsel and all other amounts due to the Trustee under Section 7.07 hereof; 
 Second: to Holders for amounts due and unpaid on the Securities for principal and interest and premium ratably, without preference or priority of any kind, according to the amounts due and payable
on the Securities for principal and interest and premium, respectively; and 
 Third: to the Company.


  
 61 









 (b) The Trustee may fix a record date and payment date for any payment to Holders pursuant
to this Section 6.10. At least 15 days before such record date, the Trustee shall mail to each Holder and the Company a notice that states the record date, the payment date and amount to be paid. 

Section 6.11 Undertaking for Costs 
 In any suit for the enforcement of any right or remedy under this Supplemental Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may
require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07 hereof or a suit by
Holders of more than 10% in outstanding principal amount of the Securities. 
 ARTICLE 7

 Section 7.01
Duties of Trustee 
 (a) If an Event of Default has occurred and is continuing, the Trustee shall exercise the rights and

satisfactory to it against such risk or liability is not reasonably assured to it. 
 Section 7.02 Rights of Trustee. 

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate,

is in fact such a Default is received by the Trustee at the Corporate Trust Office of the Trustee, and such notice references the Securities and this Indenture; 
 (j) anything in this Indenture notwithstanding, in no event shall the Trustee be liable for any special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including
but not limited to loss of profit), even if the Company has been advised as to the likelihood of such loss or damage and regardless of the form of action; and 
 (k) the permissive rights of the Trustee enumerated herein shall not be construed as duties. 
 The recitals contained herein and in the Securities, except the Trustee’s certificates of authentication, shall be taken as the statements of the Company and the Guarantors, and the Trustee or any

relating to payment of principal of, premium, if any, or interest on any Security (including payments pursuant to the redemption or required repurchase provisions of such Security), the Trustee may withhold the notice if and so long as its board of
directors, the Executive Committee of its board of directors or a committee of its Trust Officers in good faith determines that withholding the notice is in the interests of Holders. 

  
 64 









 Section 7.06 Reports by Trustee to Holders 

(a) Within 60 days after each May 15 beginning with the May 15 of the year following the date of this Supplemental Indenture,
the Trustee shall mail to each Holder a brief report that complies with Trust Indenture Act Section 313(a) (but if no event described in Trust Indenture Act §313(a) has occurred within the 12 months preceding the reporting date, no report
need be transmitted). The Trustee also shall comply with Trust Indenture Act Section 313(b). The Trustee shall also transmit by mail all reports required by Trust Indenture Act Section 313(c). 

(b) A copy of each report at the time of its mailing to Holders shall be mailed to the Company and filed with the SEC and each stock
exchange (if any) on which the Securities are listed. The Company agrees to notify promptly the Trustee whenever the Securities become listed on any stock exchange and of any delisting thereof. 

Section 7.07 Compensation and Indemnity 
 (a) The Company shall pay to the Trustee from time to time, and the Trustee shall be entitled to, reasonable compensation for its services, which may be set forth in a separate fee agreement between the
Trustee and the Company. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses incurred or
made by it, including costs of collection, costs of preparing and reviewing reports, certificates and other documents, costs of preparation and mailing of notices to Holders and reasonable costs of counsel retained by the Trustee in connection with
the delivery of an Opinion of Counsel or otherwise, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee’s agents and counsel. The
Company shall indemnify and hold harmless the Trustee (in its individual and trustee capacities) and its officers, directors and agents against any and all loss, liability, claims, action, suit, cost or expense (including reasonable attorneys’
fees) of any kind and nature whatsoever incurred by it in connection with the administration of this trust and the performance of its duties hereunder, including the costs and expenses of enforcing this Supplemental Indenture (including this
Section 7.07) and of defending itself against any claims (whether asserted by any Holder, the Company or otherwise). The Trustee shall notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee to so
notify the Company shall not relieve the Company of its obligations hereunder. The Company shall defend the claim and the Trustee may have separate counsel and the Company shall pay the fees and expenses of such counsel. The Company is not required
to reimburse any expense or indemnify against any loss, liability, claim, suit, cost or expense incurred by the Trustee through the Trustee’s own willful misconduct or negligence. 

(b) To secure the Company’s payment obligations in this Section 7.07, the Trustee shall have a lien prior to the
Securities on all money or property held or collected by the Trustee other than money or property held in trust to pay principal of, premium (if any), and interest on particular Securities. 

(c) The Company’s payment obligations pursuant to this Section 7.07 shall survive the discharge of this Supplemental
Indenture and the resignation or removal of the Trustee. When the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(a)(8) hereof with respect to the Company, the expenses are intended to constitute
expenses of administration under any Bankruptcy Law. 

  
 65

written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the

provided for in Section 7.07 hereof. 
 (e) If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee or the Holders of 10% in outstanding principal amount of the Securities may, at the expense of the Company, petition any court of competent jurisdiction for the appointment of a successor
Trustee. 
 (f) If the Trustee fails to comply with Section 7.10 hereof after written notice thereto, the Holders of
at least 10% in principal amount of the then outstanding Securities may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation or banking association without any further act shall be the successor Trustee. 

(b) If at the time such successor or successors by merger, conversion or consolidation to the Trustee shall succeed to the trusts created
by this Supplemental Indenture, any of the Securities shall have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Securities so
authenticated; and if at that time any of the Securities shall not have been authenticated, any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor to the Trustee;
and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Supplemental Indenture provided that the certificate of the Trustee shall have. 

  
 66

(3) hereof, and 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 Section, whether directly or indirectly, by reason of any reference elsewhere herein to
any such Section or by reason of any reference in any such Section to any other provision herein or in any other document and such omission to comply with such Sections shall no longer constitute a Default or an Event of Default under
Section 6.01(a)(3) (solely as it relates to Section 4.12 or Section 5.01(a)(2) or (3) hereof), Section 6.01(a)(4), Section 6.01(a)(5) or Section 6.01(a)(6) hereof or
(with respect only to Significant Subsidiaries) Section 6.01(a)(8) hereof, and the events specified in such Sections shall no longer constitute an Event of Default (this clause (2) being referred to as the “covenant defeasance
option”), but otherwise the remainder of this Supplemental Indenture and the Securities shall be unaffected thereby. The Company may exercise its legal defeasance option notwithstanding its prior exercise of its covenant defeasance option. If
the Company exercises its legal defeasance option or its covenant defeasance option, each Guarantor shall be released from its obligations with respect to its Subsidiary Guarantee as provided in Section 10.09(b) hereof. 

(c) If the Company exercises its legal defeasance option, payment of the Securities may not be accelerated because of an Event of
Default. If the Company exercises its covenant defeasance option, payment of the Securities may not be accelerated because of an Event of Default specified in Section 6.01(a)(3) (solely as it relates to Section 4.12 or
Section 5.01(a)(2) or (3)), Section 6.01(a)(4), Section 6.01(a)(5), Section 6.01(a)(6) or (with respect only to Significant Subsidiaries) Section 6.01(a)(8) hereof. 

(d) Upon satisfaction of the conditions set forth herein and upon request of the Company, the Trustee shall acknowledge in writing the
discharge of those obligations that the Company terminates. 
 (e) Notwithstanding the provisions of Section 8.01(a)
and Section 8.01(b) hereof, the obligations of the Company in Section 2.03, Section 2.05, Section 2.06, Section 2.07, Section 2.09, Section 7.07,
Section 7.08 hereof, and in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the obligations of the Company in Section 7.07, Section 8.05 and Section 8.06
hereof shall survive. 
 Section 8.02 Conditions to Defeasance 

The Company may exercise its legal defeasance option or its covenant defeasance option only if: 

(a) the Company shall have irrevocably deposited with the Trustee, in trust, for the benefit of the Holders of the Securities, cash in
U.S. dollars, non-callable Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of, premium, if any, and
interest on the outstanding Securities on the Stated Maturity or on the applicable Redemption Date, as the case may be, and the Company must specify whether the Securities are being defeased to Stated Maturity or to a particular Redemption Date;

 (b) in the case of the legal defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel in the
United States reasonably acceptable to the Trustee confirming that (1) the Company has received from, or there has been published by, the Internal Revenue Service a ruling or (2) since the Issue Date, there has been a change in the
applicable federal income tax law, in either case 

  
 68 









 
to the effect that, and based thereon such Opinion of Counsel shall confirm that, the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes
as a result of such legal defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such legal defeasance had not occurred; 

(c) in the case of the covenant defeasance option, the Company shall have delivered to the Trustee an Opinion of Counsel in the United
States reasonably acceptable to the Trustee confirming that the Holders of the outstanding Securities will not recognize income, gain or loss for federal income tax purposes as a result of such covenant defeasance and will be subject to federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such covenant defeasance option had not occurred; 
 (d) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the incurrence of Indebtedness or the grant of Liens securing such Indebtedness, all
or a portion of the proceeds of which will be applied to such deposit) or insofar as Events of Default from bankruptcy or insolvency events are concerned, at any time in the period ending on the 91st day after the date of deposit; 

(e) such deposit will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other
than this Supplemental Indenture) to which the Company or any of its Restricted Subsidiaries is a party or by which the Company or any of its Restricted Subsidiaries is bound, or if such breach, violation or default would occur, which is not waived
as of, and for all purposes, on and after, the date of such deposit; 
 (f) the Company shall have delivered to the Trustee an
Officers’ Certificate stating that the deposit was not made by the Company with the intent of preferring the Holders of Securities over the other creditors of the Company with the intent of defeating, hindering, delaying or defrauding creditors
of the Company or others; and 
 (g) the Company shall have delivered to the Trustee an Officers’ Certificate and an
Opinion of Counsel, stating that all conditions precedent relating to the legal defeasance option or the covenant defeasance option have been complied with. 
 Section 8.03 Delivery and Application of Trust Money 
 The Trustee
shall hold in trust money or Government Securities deposited with it pursuant to this Article 8. It shall apply the deposited money and the money from Government Securities in accordance with this Supplemental Indenture to the payment of
principal, premium, if any, of and interest on the Securities. 
 Section 8.04 Repayment to Company 

(a) The Trustee and each Paying Agent shall promptly turn over to the Company upon request any excess money or securities held by them
upon payment of all the Obligations under this Supplemental Indenture. 
 (b) Subject to any applicable abandoned property law,
the Trustee and each Paying Agent shall pay to the Company upon request any money held by them for the payment of principal of, or premium, if any, or interest on the Securities that remains unclaimed for two years (or any such money then held by
the Company or any Subsidiary shall be discharged from any trust hereunder), and, thereafter, Holders entitled to the money must look to the Company for payment as unsecured general 

  
 69 









 
creditors; provided, however, that, if any Definitive Securities are then outstanding, the Trustee or such Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in The New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which will not be less than 30
days from the date of such notification or publication, any unclaimed balance of such money then remaining will be repaid to the Company. 

Section 8.05 Indemnity for Government Securities 
 The Company shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed on or assessed against deposited Government Securities or the principal and interest received on such
Government Securities. 
 Section 8.06 Reinstatement 
 If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with this Article 8 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 obligations of the Company under this Supplemental Indenture and the Securities shall be revived and reinstated as though no deposit had
occurred pursuant to this Article 8 until such time as the Trustee or such Paying Agent is permitted to apply all such money or Government Securities in accordance with this Article 8; provided, however, that, if the Company has
made any payment in respect of any Securities because of the reinstatement of its obligations, the Company shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money or Government Securities held by
the Trustee or any Paying Agent. 
 ARTICLE 9 
 AMENDMENTS 
 Section 9.01 Without Consent of Holders

 (3) to provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the
Securities in the case of a merger or consolidation or sale of all or substantially all of the Company’s or such Guarantor’s properties or assets, including the addition of any required co-issuer of the Securities; 

(4) to make any change that would provide any additional rights or benefits to the Holders or that does not materially
affect the legal rights hereunder of any Holder; 
 (5) to comply with the requirements of the SEC in order to
effect or maintain the qualification of this Supplemental Indenture under the Trust Indenture Act; 

  
 70 









 (6) to add any additional Guarantor or to release any Guarantor from its

(7) to secure the Securities, including pursuant to the requirements of Section 4.05; 

(8) to conform the text of this Supplemental Indenture, the Securities or the Subsidiary Guarantees to any provision of
the “Description of the Notes” in the Company’s final prospectus supplement relating to the Initial Securities to the extent that such provision in such “Description of the Notes” was intended to set forth, verbatim or in
substance, a provision of this Supplemental Indenture, the Securities or the Subsidiary Guarantees; or 
 (9) to
provide for the issuance of Additional Securities and related Subsidiary Guarantees in accordance with this Supplemental Indenture. 

Section 9.02 With Consent of Holders 
 (a) The Company, the Guarantors and the Trustee may amend or supplement this Supplemental Indenture, the Securities or the Subsidiary Guarantees with the consent of the Holders of at least a majority in
principal amount of the outstanding Securities (including consents obtained in connection with the purchase of, or tender offer or exchange offer for, Securities). Subject to the following sentence, any existing Default or compliance with any
provision of this Supplemental Indenture, the Securities or the Subsidiary Guarantees may be waived with the consent of the Holders of at least a majority in principal amount of outstanding Securities (including consents obtained in connection with
a purchase of, or tender offer or exchange offer for, Securities). However, without the consent of each Holder, an amendment, supplement or waiver may not (with respect to any Securities held by a non-consenting Holder): 

(1) reduce the principal amount of Securities whose Holders must consent to an amendment, supplement or waiver;

 (2) reduce the principal of or change the fixed maturity of any Security or alter the provisions with respect
to the redemption or repurchase of the Securities (other than provisions relating to Section 4.07 or 4.12); 
 (3) reduce the rate of or change the time for payment of interest on any Security; 
 (4) waive a Default or Event of Default in the payment of principal of or premium, if any, or interest on the Securities (except a rescission of acceleration of the Securities by the Holders of at least a
majority in outstanding principal amount of the Securities and a waiver of the payment default that resulted from such acceleration); 
 (5) make any Security payable in money other than that stated in the Securities; 
 (6) make any change in the provisions of this Supplemental Indenture relating to waivers of past Defaults or the rights of Holders of Securities to receive payments of principal of or premium, if any, or
interest on the Securities (except as permitted by clause (7) below); 
 (7) waive a redemption or
repurchase payment with respect to any Security (other than a payment required by Section 4.07 or 4.12); or 

  
 71 









 (8) make any change in the preceding amendment, supplement and waiver
provisions of this Section 9.02(a). 
 (b) The consent of the Holders is not necessary under this
Section 9.02 to approve the particular form of any proposed amendment or waiver. It is sufficient if the consent approves the substance of the proposed amendment or waiver. 

(c) After an amendment, supplement or waiver under this Section 9.02 becomes effective, the Company shall mail to each Holder
of Securities affected thereby a notice briefly describing such amendment. The failure to give such notice to any or all Holders, or any defect therein, shall not impair or affect the validity of any amendment, supplement or waiver under this
Section 9.02. 
 Section 9.03 Compliance with Trust Indenture Act 

Every amendment to this Supplemental Indenture, the Securities or the Subsidiary Guarantees shall comply with the Trust Indenture Act as
then in effect. 
 Section 9.04 Revocation and Effect of Consents and Waivers 

(a) A consent to an amendment, supplement or waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that
Security or portion of the Security that evidences the same debt as the consenting Holder’s Security (or any Holder of a Security issued upon the registration of transfer or exchange thereof or in lieu thereof), even if notation of the
amendment, supplement or waiver is not made on the Security. However, any such Holder or subsequent Holder may revoke the consent as to such Holder’s Security or portion of the Security if the Trustee receives the written notice of revocation
before the date the amendment, supplement or waiver becomes effective. After an amendment, supplement or waiver becomes effective in accordance with its terms, it shall bind every Holder. 

(b) The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their
consent or take any other action described above or required or permitted to be taken pursuant to this Supplemental Indenture. If a record date is fixed, then notwithstanding the immediately preceding paragraph, those Persons who were Holders at the
close of business on such record date (or their duly designated proxies), and only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or not such Persons continue to be
Holders after such record date, and for this purpose the Securities then outstanding shall be computed as of such record date. No such consent shall become valid or effective more than 120 days after such record date. 

Section 9.05 Notation on or Exchange of Securities 
 If an amendment or supplement changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the
Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the
changed terms, but the failure to make the appropriate notation or to issue a new Security shall not affect the validity and effect of such amendment or supplement. 

  
 72 









 Section 9.06 Trustee to Sign Amendments 

The Trustee shall sign any amendment or supplement authorized pursuant to this Article 9 if the amendment or supplement does
not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such amendment or supplement the Trustee shall be entitled to receive, and (subject to
Section 7.01 hereof) shall be fully protected in relying upon, in addition to the documents required by Section 11.04, an Officers’ Certificate and an Opinion of Counsel each stating that the execution of such amendment
or supplement is authorized or permitted by this Supplemental Indenture. 
 ARTICLE 10 

SUBSIDIARY GUARANTEES 

Section 10.01 Subsidiary Guarantees 
 (a) Each Guarantor hereby, jointly and severally, guarantees to each Holder and to the Trustee and its successors and assigns the full and punctual payment of principal of, premium (if any) and interest
on the Securities when due, whether at Stated Maturity, or upon redemption, required repurchase pursuant to Section 4.07 or Section 4.12 hereof, acceleration or otherwise, and all other monetary obligations owing by the
Company under this Supplemental Indenture (including obligations owing to the Trustee) and the Securities (all the foregoing being hereinafter collectively called the “Guaranteed Obligations”). The Guarantors further agree that the
Guaranteed Obligations may be extended or renewed, in whole or in part, without notice or further assent from the Guarantors, and that the Guarantors will remain bound under this Article 10 notwithstanding any extension or renewal of any
Guaranteed Obligation. 
 (b) The Guarantors waive presentation to, demand of payment from and protest to the Company of any of
the Guaranteed Obligations and also waive notice of protest for nonpayment. The Guarantors waive notice of any Default under the Securities or the Guaranteed Obligations. The obligations of the Guarantors hereunder shall not be affected
by: (1) the failure of any Holder or the Trustee to assert any claim or demand or to enforce any right or remedy against the Company or any other Person under this Supplemental Indenture, the Securities or any other agreement or otherwise;
(2) any extension or renewal of any Guaranteed Obligation; (3) any rescission, waiver, amendment, modification or supplement of any of the terms or provisions of this Supplemental Indenture (other than this Article 10), the
Securities or any other agreement; (4) the release of security, if any, held by any Holder or the Trustee for the Guaranteed Obligations or any of them; (5) the failure of any Holder or the Trustee to exercise any right or remedy against
any other guarantor of the Guaranteed Obligations; (6) any change in the ownership of the Company; or (vii) any other act or thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the
risk of the Guarantors or would otherwise operate as a discharge of the Guarantors as a matter of law or equity, except for payment of the Securities in full. 
 (c) The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees herein constitute a guarantee of payment when due (and not a guarantee of collection) and waive any right to
require that any resort be had by any Holder or the Trustee to security, if any, held for payment of the Guaranteed Obligations. 
 (d) The obligations of the Guarantors hereunder shall not be subject to any reduction, limitation, impairment or termination for any reason (except to the extent provided in Section 10.02
hereof), including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to any defense, setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality or unenforceability
of the Obligations or otherwise. 

  
 73 









 (e) The Guarantors, jointly and severally, further agree that their Subsidiary Guarantees
herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy or
reorganization of the Company or otherwise. 
 (f) In furtherance of the foregoing and not in limitation of any other right
which any Holder or the Trustee has at law or in equity against the Guarantors by virtue hereof, upon the failure of the Company to pay any Guaranteed Obligation when and as the same shall become due, whether at Stated Maturity, upon redemption,
required repurchase, acceleration or otherwise, the Guarantors hereby promise to and will, upon receipt of written demand by the Trustee, forthwith pay, or cause to be paid, in cash, to the Holders or the Trustee an amount equal to the sum of
(i) the unpaid principal amount of such Guaranteed Obligations and (ii) accrued and unpaid interest on such Guaranteed Obligation (but only to the extent not prohibited by law). 

(g) The Guarantors, jointly and severally, agree that, as between the Guarantors, on the one hand, and the Holders and the Trustee, on
the other hand, (x) the maturity of the Guaranteed Obligations may be accelerated as provided in Article 6 for the purposes of the Subsidiary Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing such
acceleration in respect of the Guaranteed Obligations, and (y) in the event of any declaration of acceleration of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall
forthwith become due and payable by the Guarantors for the purposes of this Section 10.01. 
 (h) The Guarantors,
jointly and severally, also agree to pay any and all costs and expenses (including reasonable attorneys’ fees) incurred by the Trustee or any Holder in enforcing any rights under this Section 10.01. 

Section 10.02 Limitation on Liability 
 Each Guarantor, and by its acceptance of Securities, each Holder, hereby confirm that it is the intention of all such parties that the Subsidiary Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Subsidiary Guarantee. To effectuate the foregoing
intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor will be limited to the maximum amount that will, after giving effect to such maximum amount and all other contingent and fixed
liabilities of such Guarantor that are relevant under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other
Guarantor under this Article 10, result in the obligations of such Guarantor under its Subsidiary Guarantee not constituting a fraudulent transfer or conveyance. 
 Section 10.03 Execution and Delivery of Subsidiary Guarantee 
 (a) To
evidence its Subsidiary Guarantee set forth in Section 10.01, each Guarantor hereby agrees that a notation of such Subsidiary Guarantee substantially in the form attached as Exhibit B hereto will be endorsed by manual or
facsimile signature by an Officer of such Guarantor on each Security authenticated and delivered by the Trustee and that this Supplemental Indenture (or a supplemental indenture substantially in form of Exhibit C hereof) will be executed on
behalf of such Guarantor by one of its Officers. 

  
 74 









 (b) Each Guarantor hereby agrees that its Subsidiary Guarantee set forth in
Section 10.01 will remain in full force and effect notwithstanding any failure to endorse on each Security a notation of such Subsidiary Guarantee. If an Officer whose facsimile signature is on the Subsidiary Guarantee no longer holds
that office at the time the Trustee authenticates the Security on which the Subsidiary Guarantee is endorsed, the Subsidiary Guarantee will be valid nevertheless. 
 (c) The delivery of any Security by the Trustee, after the authentication thereof hereunder, will constitute due delivery of the Subsidiary Guarantee set forth in this Supplemental Indenture on behalf of
the Guarantors. 
 Section 10.04 Successors and Assigns 
 Except as otherwise provided in Section 10.09 hereof, this Article 10 shall be binding upon the Guarantors and their successors and assigns and shall inure to the benefit of the
successors and assigns of the Trustee and the Holders and, in the event of any transfer or assignment of rights in accordance with the terms of this Supplemental Indenture by any Holder or the Trustee, the rights and privileges conferred upon that
party in this Supplemental Indenture and in the Securities shall automatically extend to and be vested in such transferee or assignee, all subject to the terms and conditions of this Supplemental Indenture, the Securities and the Subsidiary
Guarantees. 
 Section 10.05 No Waiver 
 Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege under this Article 10 shall operate as a waiver thereof, nor shall a
single or partial exercise thereof preclude any other or further exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified are cumulative and not exclusive of any other
rights, remedies or benefits which either may have under this Article 10 at law, in equity, by statute or otherwise. 

Section 10.06 Right of Contribution 
 Each Guarantor hereby agrees that to the extent that a Guarantor shall have paid more than its proportionate share of any payment made hereunder, such Guarantor shall be entitled to seek and receive
contribution from and against any other Guarantor hereunder who has not paid its proportionate share of such payment. Each Guarantor’s right of contribution shall be subject to the terms and conditions of this Article 10. The provisions
of this Section 10.06 shall in no respect limit the obligations and liabilities of any Guarantor to the Trustee and the Holders and each Guarantor shall remain liable to the Trustee and the Holders for the full amount guaranteed by such
Guarantor hereunder. 
 Section 10.07 No Subrogation 
 Notwithstanding any payment or payments made by any of the Guarantors hereunder, no Guarantor shall be entitled to exercise any rights of subrogation it may have to any of the rights of the Trustee or any
Holder against the Company or any other Guarantor or any collateral security or guarantee or right of offset held by the Trustee or any Holder for the payment of the Guaranteed Obligations, nor shall any Guarantor seek or be entitled to seek any
contribution or reimbursement from the Company or any other Guarantor in respect of payments made by such Guarantor hereunder, until all amounts owing to the Trustee and the Holders by the Company on account of the Guaranteed Obligations are paid in
full. If any amount shall be paid to any Guarantor on account of such subrogation rights at any time when all of the Obligations shall not have been paid in full, such amount shall be held by such Guarantor in trust for the Trustee and the Holders,
segregated from other funds of such Guarantor, and shall, forthwith upon 

  
 75 









 
receipt by such Guarantor, be turned over to the Trustee in the exact form received by such Guarantor (duly indorsed by such Guarantor to the Trustee, if required), to be applied against the
Guaranteed Obligations. 
 Section 10.08 Modification 
 No modification, amendment or waiver of any provision of this Article 10, nor the consent to any departure by the Guarantors therefrom, shall in any event be effective unless the same shall be made
in accordance with Article 9 hereof. No notice to or demand on the Guarantors in any case shall entitle the Guarantors to any other or further notice or demand in the same, similar or other circumstances. 

Section 10.09 Merger, Consolidation or Sale of Assets of a Guarantor; Release of a Guarantor 

(a) To the extent that the Subsidiary Guarantee of a Guarantor has not been released in accordance with the provisions of this
Supplemental Indenture, such 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, another Person (whether or not such Guarantor is the resulting,
transferee or surviving Person) other than the Company or another Guarantor, unless: 
 (1) immediately after
giving effect to such transaction, no Default or Event of Default exists; and 
 (2) either: 

(A) 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 Guarantor) unconditionally assumes, pursuant to a supplemental indenture substantially in the form of Exhibit C hereto, all the obligations of such Guarantor under this
Supplemental Indenture, the Securities and its Subsidiary Guarantee on terms set forth therein; or 
 (B) the Net
Proceeds of such sale or other disposition are applied in accordance with Section 4.07. 
 (b) The Subsidiary
Guarantee of a Guarantor shall be automatically and unconditionally released: 
 (1) in connection with any sale
or other disposition of all or substantially all of the properties or assets of such Guarantor (including by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary
of the Company, if the sale or other disposition complies with Section 4.07; 
 (2) in connection
with any sale or other disposition of all of the Capital Stock of such Guarantor to a Person that is not (either before or after giving effect to such transaction) a Restricted Subsidiary of the Company, if the sale or other disposition complies
with Section 4.07; 
 (3) if such Guarantor is a Restricted Subsidiary and the Company designates
such Guarantor as an Unrestricted Subsidiary in accordance with Section 4.09; 

  
 76 









 (4) upon the exercise by the Company of its legal defeasance option or
covenant defeasance option in accordance with Section 8.01(b) or upon satisfaction and discharge of this Supplemental Indenture in accordance with Section 8.01(a); 

(5) upon the liquidation or dissolution of such Guarantor provided that no Default or Event of Default has occurred
and is continuing; or 
 (6) at any time after the occurrence of an Investment Grade Rating Event, such Guarantor
does not have outstanding Indebtedness, and it does not guarantee Indebtedness of the Company or any other Guarantor, in each case in excess of a De Minimis Amount. 
 (c) Upon delivery by the Company to the Trustee of an Officers’ Certificate to the effect that any of the conditions described in clauses (1) – (6) of Section 10.09(b) has
occurred, the Trustee shall execute any supplemental indenture or other documents reasonably requested by the Company in order to evidence the release of any Guarantor from its obligations under its Subsidiary Guarantee and this Supplemental
Indenture.

	2.	The Securities. 

 2.1(a)
Form and Dating. Initial Private Securities offered and sold in reliance on Rule 144A (“Rule 144A Securities”) under the Securities Act (“Rule 144A”) or in reliance on Regulation S (“Regulation S
Securities”) under the Securities Act (“Regulation S”), in each case as provided in the Purchase Agreement and Private Exchange Securities, as provided in the Registration Rights Agreement shall be issued initially in the form of
one or more permanent global securities in definitive, fully registered form without interest coupons with the global securities legend and restricted securities legend set forth in Exhibit 1 hereto (each, unless and until becoming an Unrestricted
Initial Security in accordance with Section 2.3(b)(ii) below, a “Restricted Global Security”), which shall be deposited on behalf of the purchasers of the Initial Private Securities represented thereby with the Trustee, as Securities
Custodian (or with such other custodian as the Depositary may direct), and registered in the name of the Depositary or a nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided. Beneficial
interests in a Restricted Global Security representing Initial Private Securities sold in reliance on either Rule 144A or Regulation S may be held through Euroclear or Clearstream, as indirect participants in the Depositary. The aggregate
principal amount of the Restricted Global Securities may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee as hereinafter provided. Exchange Securities and Unrestricted
Initial Securities shall be issued in global form (with the Global Security Legend set forth in Exhibit 1 hereto) or in certificated form as provided in Section 2.4 of this Appendix. Exchange Securities issued in global form and Restricted
Global Securities are sometimes referred to in this Appendix as “Global Securities”. 
 (b) Book-Entry
Provisions. This Section 2.1(b) shall apply only to a Global Security deposited with or on behalf of the Depositary. 

The Company shall execute and the Trustee shall, in accordance with this Section 2.1(b), authenticate and deliver initially one or
more Global Securities that (i) shall be registered in the name of the Depositary for such Global Security or Global Securities or the nominee of such Depositary and (ii) shall be delivered by the Trustee to such Depositary or pursuant to
such Depositary’s instructions or held by the Trustee as Securities Custodian. If such Global Securities are Restricted Global Securities, then separate Global Securities shall be issued to represent Rule 144A Securities and
Regulation S Securities so long as required by law or the Depositary. 
 Members of, or participants in, the Depositary
(“Agent Members”) shall have no rights under the Supplemental Indenture with respect to any Global Security held on their behalf by the Depositary or by the Trustee as the custodian of the Depositary or under such Global Security, and the
Company, the Trustee and any agent of the Company or the Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Security for all purposes whatsoever. Notwithstanding the foregoing, nothing herein shall prevent the
Company, the Trustee or any agent of the Company or the Trustee from giving effect to any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Agent Members, the operation of
customary practices of such Depositary governing the exercise of the rights of a holder of a beneficial interest in any Global Security. 
 Prior to the expiration of the period through and including the 40th day after the later of the commencement of the offering of any Private Securities and the original issue date of such 

Rule 144A/Regulation S Appendix – Page 3 of 10 







 
Private Securities (such period, the “Distribution Compliance Period”), a beneficial interest in a Restricted Global Security representing Regulation S Securities may be
transferred to a Person who takes delivery in the form of an interest in a Restricted Global Security representing Rule 144A Securities only if (i) such exchange occurs in connection with a transfer pursuant to Rule 144A, (ii) the
transferor first delivers to the Trustee a written certificate (in the form provided in Exhibit 1 hereto) to the effect that such transfer is being made to a Person who, in the case of Rule 144A Securities, the transferor reasonably believes is
purchasing for its own account or accounts as to which it exercises sole investment discretion and that such Person is a QIB, in each case in a transaction meeting the requirements of Rule 144A and (iii) the transfer is in accordance with any
applicable securities laws of any state of the United States or any other jurisdiction. After the expiration of the Distribution Compliance Period, such certification requirements shall not apply to such transfers of beneficial interests in a
Restricted Global Security representing Regulation S Securities. 
 Beneficial interests in a Restricted Global Security
representing Rule 144A Securities may be transferred to a Person who takes delivery in the form of an interest in a Restricted Global Security representing Regulation S Securities, whether before or after the expiration of the Distribution
Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form provided in Exhibit 1 hereto) to the effect that such transfer is being made in accordance with Rule 904 of Regulation S or Rule 144 (if
available) and that, if such transfer occurs prior to the expiration of the Restricted Period, the interest transferred will be held immediately thereafter through Euroclear or Clearstream. 

(c) Certificated Securities. Except as provided in Section 2.3 or 2.4, owners of beneficial interests in Restricted Global
Securities shall not be entitled to receive physical delivery of certificated Securities. Certificated Securities shall not be exchangeable for beneficial interests in Global Securities. 

2.2 Authentication. The Trustee shall authenticate and deliver: (1) on the Private Issue Date, an aggregate principal amount
of $200.0 million of Securities, (2) any Additional Private Securities for original issue in an aggregate principal amount specified in the written order of the Company pursuant to Section 2.02 of the Supplemental Indenture and
(3) Exchange Securities or Private Exchange Securities for issue only in a Registered Exchange Offer or a Private Exchange, respectively, pursuant to a Registration Rights Agreement, for a like principal amount of Exchange Securities or Initial
Private Securities, respectively, in each case upon a written order of the Company. Such order shall specify the amount of the Securities to be authenticated, the date on which the original issue of Securities is to be authenticated and to whom the
Securities shall be registered and delivered. 
  

	 	2.3	Transfer and Exchange. 

  

	 	(a)	Transfer and Exchange of Global Securities. 

 (i) The transfer and exchange of Global Securities or beneficial interests therein shall be effected through the Depositary, in accordance with the Supplemental Indenture (including applicable
restrictions on transfer set forth herein, if any) and the procedures of the Depositary therefor. A transferor of a beneficial interest in a Global Security shall deliver to the Registrar a written order given in accordance with the
Depositary’s 
 Rule 144A/Regulation S Appendix – Page 4 of 10 







 
procedures containing information regarding the participant account of the Depositary to be credited with a beneficial interest in the Global Security. The Registrar shall, in accordance with
such instructions instruct the Depositary to credit to the account of the Person specified in such instructions a beneficial interest in the Global Security and to debit the account of the Person making the transfer of the beneficial interest in the
Global Security being transferred. 
 (ii) Notwithstanding any other provisions of this Appendix, a Global
Security may not be transferred as a whole except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or by the Depositary or any such nominee to a successor
Depositary or a nominee of such successor Depositary. 
 (iii) In the event that a Restricted Global Security is
exchanged for Securities in certificated form pursuant to Section 2.4 of this Appendix, prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Securities, such
Securities may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Private Securities intended to
ensure that such transfers comply with Rule 144A or Regulation S, as the case may be) and such other procedures as may from time to time be adopted by the Company. 

 

	 	(b)	Legend. 


(i) Except as permitted by the following paragraphs (ii), (iii) and (iv), each Security certificate evidencing the
Restricted Global Securities (and all Securities issued in exchange therefor or in substitution thereof, other than Exchange Securities) shall bear a legend in substantially the following form: 

THIS SECURITY AND THE GUARANTEES HEREOF HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), OR ANY STATE SECURITIES LAWS. NEITHER THIS SECURITY NOR THE GUARANTEES HEREOF NOR ANY INTEREST OR PARTICIPATION HEREIN MAY BE OFFERED, SOLD, ASSIGNED, TRANSFERRED, PLEDGED, ENCUMBERED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF SUCH
REGISTRATION OR UNLESS SUCH TRANSACTION IS EXEMPT FROM, OR NOT SUBJECT TO, THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT. THE HOLDER OF THIS SECURITY AND THE GUARANTEES HEREOF BY ITS ACCEPTANCE HEREOF (1) REPRESENTS THAT (A) IT IS A
“QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT) OR (B) IT IS NOT A U.S. PERSON AND IS ACQUIRING SUCH NOTE IN AN “OFFSHORE TRANSACTION” PURSUANT TO RULE 904 OF REGULATION S UNDER THE
SECURITIES ACT AND (2) AGREES TO OFFER, SELL OR OTHERWISE TRANSFER SUCH SECURITY, PRIOR TO THE DATE WHICH IS ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF OR THE DATE OF ANY SUBSEQUENT REOPENING OF THE SECURITIES AND THE LAST DATE
ON WHICH 
 Rule 144A/Regulation S Appendix – Page 5 of 10 







 
THE COMPANY OR ANY AFFILIATE OF THE COMPANY WAS THE OWNER OF THIS SECURITY AND THE GUARANTEES HEREOF (OR ANY PREDECESSOR OF THIS SECURITY AND THE GUARANTEES HEREOF) (THE “RESALE RESTRICTION
TERMINATION DATE”) ONLY (A) TO THE COMPANY OR ANY SUBSIDIARY THEREOF, (B) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A
UNDER THE SECURITIES ACT (“RULE 144A”), TO A PERSON IT REASONABLY BELIEVES IS A “QUALIFIED INSTITUTIONAL BUYER” AS DEFINED IN RULE 144A THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO
WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, (D) PURSUANT TO OFFERS AND SALES TO NON-U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES IN ACCORDANCE WITH REGULATION S UNDER THE SECURITIES ACT, (E) PURSUANT
TO RULE 144 UNDER THE SECURITIES ACT OR (F) PURSUANT TO ANOTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT, SUBJECT TO THE COMPANY’S AND THE TRUSTEE’S RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER
(i) PURSUANT TO CLAUSE (D) PRIOR TO THE END OF THE 40 DAY DISTRIBUTION COMPLIANCE PERIOD WITHIN THE MEANING OF REGULATION S UNDER THE SECURITIES ACT OR PURSUANT TO CLAUSE (E) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE TO REQUIRE
THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION AND/OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM, AND (ii) IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THIS SECURITY IS COMPLETED
AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE. THIS LEGEND WILL BE REMOVED UPON THE REQUEST OF A HOLDER OR THE COMPANY ON OR AFTER THE RESALE RESTRICTION TERMINATION DATE. 

(ii) The Company, acting in its discretion, may remove the legend set forth in paragraph (i) above from any Transfer
Restricted Security at any time on or after the Distribution Compliance Period applicable to such Transfer Restricted Security. Without limiting the generality of the preceding sentence, the Company may effect such removal by issuing and delivering,
in exchange for such Transfer Restricted Security, an Unrestricted Initial Security without such legend, registered to the same holder and in an equal principal amount, and upon receipt by the Trustee of a written order of the Company stating that
the Distribution Compliance Period applicable to such Transfer Restricted Security has expired and requesting the authentication and delivery of an Unrestricted Initial Security in exchange therefor (which order shall not be required to be
accompanied by any Opinion of Counsel or any other document) given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Distribution Compliance Period), the Trustee shall
authenticate 
 Rule 144A/Regulation S Appendix – Page 6 of 10 







 
and deliver such Unrestricted Initial Security to the Depository or pursuant to such Depository’s instructions or hold such Security as Securities Custodian for the Depository and shall
request the Depository to, or, if the Trustee is Securities Custodian of such Transfer Restricted Security, shall itself, surrender such Transfer Restricted Security in exchange for such Unrestricted Initial Securities without such legend and
thereupon cancel such Transfer Restricted Security so surrendered, all as directed in such order. For purposes of determining whether the Distribution Compliance Period has expired with respect to any Securities evidenced by a Transfer Restricted
Security or delivering any order pursuant to this Section 2.3(b)(ii) with respect to such Securities, (i) only those Securities which a Principal Officer of the Company actually knows (after reasonable inquiry) to be or to have been owned
by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the
treasurer or the principal accounting officer of the Company. 
 For purposes of this Section 2.3(b)(ii),
all provisions relating to the removal of the legend set forth in paragraph (i) above shall relate, if the Distribution Compliance Period has expired only with respect to a portion of the Securities evidenced by a Transfer Restricted Security,
to such portion of the Securities so evidenced as to which the Distribution Compliance Period has expired. 

Each holder of any Securities evidenced by any Restricted Global Security, by its acceptance thereof, (A) authorizes
and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s behalf, as the Depository or the
Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depository or the Trustee may require, or as shall
otherwise be necessary to effect, the removal of the legend set forth in Section 2.3(b)(i) (including by means of the exchange of all or the portion of such Restricted Global Security evidencing such Security for a certificate evidencing such
Security that does not bear such legend) at any time after the Distribution Compliance Period. 
 (iii) Upon any
sale or transfer of a Transfer Restricted Security (including any Transfer Restricted Security represented by a Restricted Global Security) pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange
such Transfer Restricted Security for a certificated Security that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Security, if the transferor thereof certifies in writing to the
Registrar that such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Security). 
 (iv) After a transfer of any Initial Private Securities or Private Exchange Securities pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Initial
Private Securities or Private Exchange Securities, as the case may be, all requirements pertaining to legends on such Private Security or such Private Exchange Security will cease to apply, the requirements requiring any such 

Rule 144A/Regulation S Appendix – Page 7 of 10 







 
Private Security or such Private Exchange Security issued to certain Holders be issued in global form will cease to apply, and a certificated Private Security or Private Exchange Security or a
Private Security or Private Exchange Security in global form, in each case without restrictive transfer legends, will be available to the transferee of the Holder of such Initial Private Securities or Private Exchange Securities upon exchange of
such transferring Holder’s certificated Initial Private Securities or Private Exchange Securities or directions to transfer such Holder’s interest in the Global Security, as applicable. 

(v) Upon the consummation of a Registered Exchange Offer with respect to the Initial Private Securities, all requirements
pertaining to such Initial Private Securities that Initial Private Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Private Securities that do not exchange their Initial Private
Securities, and Exchange Securities in certificated or global form will be available to Holders that exchange such Initial Private Securities in such Registered Exchange Offer. 

(vi) Upon the consummation of a Private Exchange with respect to the Initial Private Securities, all requirements
pertaining to such Initial Private Securities that Initial Private Securities issued to certain Holders be issued in global form will still apply with respect to Holders of such Initial Private Securities that do not exchange their Initial Private
Securities, and Private Exchange Securities in global form with the global Securities legend and the Restricted Securities legend set forth in Exhibit 1 hereto will be available to Holders that exchange such Initial Private Securities in such
Private Exchange. 
 (c) Cancellation or Adjustment of Global Security. At such time as all beneficial interests in a
Global Security have either been exchanged for certificated Securities, redeemed, purchased or canceled, such Global Security shall be returned to the Depositary for cancellation or retained and canceled by the Trustee. At any time prior to such
cancellation, if any beneficial interest in a Global Security is exchanged for certificated Securities, redeemed, purchased or canceled, the principal amount of Securities represented by such Global Security shall be reduced and an adjustment shall
be made on the books and records of the Trustee (if it is then the Securities Custodian for such Global Security) with respect to such Global Security, by the Trustee or the Securities Custodian, to reflect such reduction. 

(d) Obligations with Respect to Transfers and Exchanges of Securities. 

(i) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate
certificated Securities and Global Securities at the Registrar’s request. 
 (ii) No service charge shall be
made for any registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any transfer tax, assessments or similar governmental charge payable in connection therewith (other than any such transfer taxes,
assessments or similar governmental charge payable upon exchange or transfer pursuant to Sections 3.06, 4.07, 4.12 and 9.05 of the Supplemental Indenture). 
 Rule 144A/Regulation S Appendix – Page 8 of 10 







 (iii) The Registrar shall not be required to register the transfer of or
exchange of any Security or portion of a Security selected for redemption, except for the unredeemed portion of any Security being redeemed in part. Also, it need not exchange or register the transfer of any Securities for a period of 15 days before
a selection of Securities to be redeemed. 
 (iv) Prior to the due presentation for registration of transfer of
any Security, the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar may deem and treat the Person in whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal
of, premium, if any, and interest on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Company, the Guarantors, the Trustee, the Paying Agent or the Registrar shall be affected by notice to
the contrary. 
 (v) All Securities issued upon any transfer or exchange pursuant to the terms of the
Supplemental Indenture shall evidence the same debt and shall be entitled to the same benefits under the Supplemental Indenture as the Securities surrendered upon such transfer or exchange. 

(e) No Obligation of the Trustee.

Supplemental Indenture, dated as of March 8, 2012 (the “Supplemental Indenture”), among the Company, the Guarantors named therein and the Trustee. The terms of the Securities include those stated in the Supplemental Indenture and
those made part of the Supplemental Indenture by reference to the Trust Indenture Act. The Securities are subject to all such terms, and Holders are referred to the Supplemental Indenture and such Act for a statement of such terms. To the extent any
provision of this Security conflicts with the express provisions of the Supplemental Indenture, the provisions of the Supplemental Indenture shall govern and be controlling (to the extent permitted by law). The Securities are unsecured obligations
of the Company. The Company has issued $675,000,000 aggregate principal amount of Securities. The Company may issue Additional Securities under the Supplemental Indenture, subject to Section 4.03 of the Supplemental Indenture;
provided, however, that no Additional Securities may be issued at a price that would cause such Additional Securities to have “original issue discount” within the meaning of Section 1273 of the Code 

5. Redemption. 
 (a) On or after March 1, 2016, the Company may redeem all or a part of the Securities at any time and from time to time at its option at the following Redemption Prices (expressed as percentages of
the principal amount redeemed) plus accrued and unpaid interest on the Securities, if any, to the applicable Redemption Date, if redeemed during the 12-month period beginning on March 1 of the years indicated below: 

 

					
	 Year
	  	Redemption Price

	 2018
	  	 	101.125	% 
	 2019 and thereafter
	  	 	100.000	% 

 (b) At any time and from time to time before March 1, 2014, the Company may on any
one or more occasions redeem up to 35% of the aggregate principal amount of the outstanding Securities (including any Additional Securities) at a Redemption Price of 106.750% of the principal amount of such Securities, plus accrued and unpaid
interest, if any, thereon to the Redemption Date, with the net cash proceeds (other than Designated Proceeds) of any one or more Equity Offerings; provided that (i) at least 65% of the aggregate principal amount of the Securities (including any
Additional Securities) issued under the Supplemental Indenture remains outstanding immediately after each such redemption and (ii) each such redemption occurs within 180 days of the date of the closing of the related Equity Offering.

 (c) In addition, at any time and from time to time prior to March 1, 2016, the Company may, at its
option, redeem all or part of the Securities at a Redemption Price equal to 
 (i) 100% of the principal amount thereof, plus

 (ii) the Applicable Premium, plus 
 (iii) accrued and unpaid interest, if any, thereon to, the Redemption Date. 
 (d) If Holders of not less than 95% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the Company, or any
third party making a Change of Control Offer in lieu of the Company as permitted by Section 4.12 of the Supplemental Indenture, purchases all of the Securities validly 

  
 A-3









 
tendered and not withdrawn by such Holders, the Company or such third party will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days
following such purchase pursuant to the Change of Control Offer, to redeem all Securities that remain outstanding following such purchase at a Redemption Price in cash equal to the applicable Change of Control Payment plus, to the extent not
included in the Change of Control Payment, accrued and unpaid interest thereon to the Redemption Date. 
 6. Denominations,
Transfer, Exchange. The Securities are in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of Securities may be registered and Securities may be exchanged as
provided in the Supplemental Indenture. The Registrar or the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Company may require a Holder to pay any transfer tax or similar
governmental charge or other fee required by law and payable in connection therewith. The Company need not exchange or register the transfer of any Security or portion of a Security selected for redemption, except for the unredeemed portion of any
Security being redeemed in part. Also, the Company need not exchange or register the transfer of any Securities for a period of 15 days before the day of any selection of Securities to be redeemed or during the period between a record date and the
corresponding Interest Payment Date. 
 If this is a Global Security, this Security represents the aggregate principal amount of
outstanding Securities from time to time endorsed hereon, and the aggregate principal amount of outstanding Securities represented by this Security may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions
in accordance with the Supplemental Indenture. 
 7. Persons Deemed Owners. The registered Holder of a Security may be
treated as its owner for all purposes. 
 8. Amendment, Supplement and Waiver. Subject to certain exceptions, the
Supplemental Indenture and the Securities may be amended or supplemented with the written consent of the Holders of at least a majority in outstanding principal amount of the Securities, and any existing Default or compliance with any provision of
the Supplemental Indenture or the Securities may be waived with the written consent of the Holders of at least a majority in outstanding principal amount of the Securities. Without the consent of any Holder of a Security, the Supplemental Indenture,
the Subsidiary Guarantees or the Securities may be amended or supplemented (a) to cure any ambiguity, defect or inconsistency, (b) to provide for uncertificated Securities in addition to or in place of certificated Securities, (c) to
provide for the assumption of the Company’s or a Guarantor’s obligations to Holders of the Securities in specified circumstances, (d) to make any change that would provide any additional rights or benefits to the Holders or that
does not materially affect the legal rights of any Holder, (e) to comply with any requirement of the SEC in connection with qualifying the Supplemental Indenture under the Trust Indenture Act or maintaining such qualification, (f) to add
or release Guarantors in compliance with the Supplemental Indenture, to appoint a successor Trustee or to add additional Events of Default, (g) to secure the Securities, (h) to conform the text of the Supplemental Indenture, the Securities
or the Subsidiary Guarantees to “Description of the Notes” in the Company’s prospectus supplement respecting the Initial Securities and (i) to provide for the issuance of Additional Securities and related Subsidiary Guarantees in
accordance with the Supplemental Indenture. 
 9. Defaults. If an Event of Default shall occur and be continuing, the
principal of all the Securities may be declared due and payable in the manner and with the effect provided in the Supplemental Indenture.

the manual signature of the Trustee or an Authenticating Agent.

of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the other identification numbers placed thereon.
