 WHEREAS, the Company has duly authorized the execution and delivery of this Supplemental Indenture to establish the Notes as a series of Securities under the Base Indenture and to provide for, among other
things, the issuance of and the form and terms of the Notes for purposes of the Notes and the Holders thereof; and 
 WHEREAS,
all things necessary have been done to make the Notes, when executed by the Company and authenticated and delivered hereunder and duly issued by the Company, the valid obligations of the Company, and to make this Supplemental Indenture a valid

 Except insofar as
herein otherwise expressly provided, all the definitions, provisions, terms and conditions of the Base Indenture shall remain in full force and effect. The Base Indenture, as amended and supplemented by this Supplemental Indenture, is in all

 (b) The Trustee shall authenticate or deliver the Notes for original issue in an initial aggregate principal amount of $250,000,000 upon receipt of a Company Order for the authentication and delivery of
the Notes. The Company may from time to time issue additional Notes in accordance with Section 2.01 of the Base Indenture. The Notes issued originally hereunder, together with any additional Notes subsequently issued, shall be treated as a

Interest Payment Date, commencing on September 15, 2012, to the Person in whose name the Notes are registered at the close of business on the Regular Record Date, and at 

  
 7 








 
Maturity, until the principal thereof is paid or made available for payment. Interest on the Notes will be calculated on the basis of a 360-day year comprised of twelve 30-day months.

 (e) If any Interest Payment Date, Redemption Date, Change of Control Payment Date or Maturity date is not a Business Day, the
payment of principal, premium, if any, and interest, as applicable, will be made on the next succeeding Business Day. No interest will accrue on the amount so payable for the period from and after any Interest Payment Date, Redemption Date, Change
of Control Payment Date or the Maturity date, as the case may be, to the date payment is made on such next succeeding Business Day. 
 (f) All amounts payable in connection with the Notes shall be denominated and payable in the lawful currency of the United States. 
 (g) The Notes shall be payable and may be presented for registration of transfer and exchange, without service charge, at the office of the Company maintained for such purpose in the State of New York,

Manhattan. The Company shall enter into an appropriate agency agreement with any agent not a party to the Indenture that shall implement the provisions of the Indenture that relate to such agent. The Company shall give prompt written notice to the
Trustee of the name and address of any such agent and any change in the address of such agent. If the Company fails to maintain a Paying Agent, Security Registrar and/or agent for service of notices and demands, the Trustee shall act as such Paying

acceptance of an appointment by a successor Paying Agent or Security Registrar, as the case may be, as evidenced by an appropriate agency agreement entered into by the Company and such successor and delivered to the Trustee or (ii) notification
to the Trustee that the Trustee shall serve as such Paying Agent or Security Registrar until the appointment of a successor agent in accordance with clause (i) of this proviso. The Company or any of its Subsidiaries or any of their Affiliates

 8 








 (b) 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 Security Registrar, the Company shall furnish, or cause the Security Registrar to furnish, to the Trustee, in writing at least

(i) Semiannual interest on any Notes that is payable, and is punctually paid or duly provided for, on any Interest Payment
Date shall be paid to the Person in whose name such Notes are registered at the close of business on the Regular Record Date for such interest at the office or agency of the Company maintained for such purpose. Each installment of interest on any
Notes shall be paid by check mailed to the address of such registered Holder as shown on the Security Register. In the case of a Global Security, semiannual interest payable on any applicable Interest Payment Date will be paid to the Depositary,
with respect to that portion of such Global Security held for its account by wire transfer of same-day funds for the purpose of permitting the Depositary to credit the interest received by it in respect of such Global Security to the accounts of the
Beneficial Owners thereof. 
 (ii) Except as otherwise specified with respect to the Notes, any semiannual
interest on any Notes that is payable, but is not punctually paid or duly provided for, on any applicable payment date (herein called “Defaulted Interest,” which term shall include any accrued and unpaid interest that has accrued on
such defaulted amount), shall forthwith cease to be payable to the Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest shall be paid by the Company as provided for in Section 2.08
of the Base Indenture. 
 (iii) Subject to the foregoing provisions of Section 2.02 of this Supplemental
Indenture and Section 2.08 of the Base Indenture, Notes delivered under this Supplemental Indenture upon registration of transfer of or in exchange for or in lieu of any other Notes shall carry the rights to semiannual interest accrued and
unpaid, and to accrue interest, which were carried by such other Notes. 
 (d) Sinking Fund. There shall be no sinking
fund provided for the Notes. 
 SECTION 2.03 Optional Redemption by the Company. 

(a) Right to Redeem; Notice to Trustee, Paying Agent and Holders. The Company, at its option, may at any time or from time to time
redeem the Notes in whole or in part at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be redeemed and (2) the sum of the present values of the Remaining Scheduled Payments on such Notes
discounted to the date of redemption, on a semiannual basis (assuming a 360-day 

  
 9 








 
year consisting of twelve 30-day months), at a rate equal to the sum of the applicable Treasury Rate plus 35 basis points (the “Redemption Price”), plus in either case accrued
and unpaid interest thereon to, but excluding, the Redemption Date. On and after the Redemption Date, interest will cease to accrue on the Notes or any portion of the Notes called for redemption (unless the Company defaults in the payment of the
Redemption Price and accrued interest). 
 (b) Fewer Than All Outstanding Notes to Be Redeemed. If fewer than all of the
outstanding Notes are to be redeemed, the Notes to be redeemed shall be selected in Principal Amounts of $2,000 or integral multiples of $1,000 in excess thereof, and in compliance with the applicable policies and procedures of the Depositary (or if
the Notes are not held by a Depositary, the Trustee shall effect such selection pro rata, by lot or by any other method as the Trustee considers fair and appropriate). The Trustee will make such selection promptly following receipt of a notice from
the Company setting forth the principal amount of the Notes to be redeemed and the proposed Redemption Date and delivered to the Trustee not less than 45 days (unless a shorter period shall be satisfactory to the Trustee) prior to the proposed
Redemption Date. 
 (c) Notice of Redemption. If the Company elects to redeem Notes pursuant to Section 2.03(a)
hereof, at least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption by first-class mail to the Trustee, the Paying Agent and each Holder of Notes to be redeemed at such
Holder’s address as it appears on the Security Register or otherwise in accordance with the Depositary’s procedures. Notices of redemption may not be conditional. Any notice that is mailed in the manner herein provided shall be
conclusively presumed to have been duly given, whether or not the registered Holder received the notice. In any case, failure to duly give such notice to the Holder of any Note designated for redemption in whole or in part, or any defect in the
notice, shall not affect the validity of the proceedings for the redemption of any other Note. 
 The notice shall identify the
Notes to be redeemed and shall state: 
 (i) the Redemption Date; 

(ii) the Redemption Price; 
 (iii) the name and address of the Paying Agent; 
 (iv) that Notes
called for redemption must be presented and surrendered to the Paying Agent to collect the Redemption Price; 

(v) that, unless the Company defaults in making payment of such Redemption Price, interest, if any, on the Notes called
for redemption will cease to accrue on and after the Redemption Date, and the only remaining right of the Holder will be to receive payment of the Redemption Price upon presentation and surrender to the Paying Agent of the Notes; 

(vi) if any Note is to be redeemed in part only, the certificate number and portion of the Principal Amount of such Note
that is to be redeemed and that, after 

  
 10 









 
the Redemption Date upon surrender of such Note, a new Note or Notes in Principal Amount equal to the unredeemed portion shall be issued in the name of the Holder upon cancellation of the
original Note; 
 (vii) the paragraph of the Notes and/or Section of this Supplemental Indenture pursuant to
which the Notes or portions thereof called for redemption are being redeemed; and 
 (viii) the CUSIP and ISIN
number or numbers for the Notes called for redemption and that no representation is made as to the correctness or accuracy of any such CUSIP or ISIN number that is listed in such notice or printed on the Notes. 

At the Company’s request, made at least five Business Days prior to the date upon which such notice is to be mailed, the Paying
Agent shall give the notice of redemption in the Company’s name and at the Company’s expense. 
 (d) Effect of
Notice of Redemption. Once notice of redemption is mailed in accordance with Section 2.03(c) hereof, Notes called for redemption become due and payable on the Redemption Date and at the Redemption Price. Upon presentation and surrender to
the Paying Agent, Notes called for redemption shall be paid at the Redemption Price. 
 (e) Deposit of Redemption Price.
On or before 10:00 a.m. (New York City time) on the Redemption Date, the Company shall deposit with the Trustee or the Paying Agent an amount of money sufficient to pay the Redemption Price of, and any accrued and unpaid interest with respect to all
the Notes to be redeemed on that date other than the Notes or portions thereof called for redemption which on or prior thereto have been delivered by the Company to the Security Registrar for cancellation. The Trustee or the Paying Agent shall, as
promptly as practicable, return to the Company any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the Redemption Price of, and any accrued and unpaid interest with respect to the Notes
to be redeemed. 
 The Company shall require each Paying Agent (other than the Trustee) to agree in writing that the Paying
Agent shall hold in trust for the benefit of Holders or the Trustee all money held by the Paying Agent for the payment of the Redemption Price and any accrued and unpaid interest and shall notify the Trustee of any default by the Company in making
any such payment. If the Company or an Affiliate of the Company acts as Paying Agent, it shall segregate the funds sufficient to pay the Redemption Price plus accrued interest and hold such funds as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money held by it to the Trustee and to account for any funds disbursed by the Paying Agent. Upon doing so, the Paying Agent shall have no further liability for the money delivered to the Trustee. 

(f) With respect to the Notes only, Sections 10.02 through 10.06 of the Base Indenture shall not be applicable. 

SECTION 2.04 Change of Control Offer. (a) If a Change of Control Repurchase Event occurs, each Holder shall have the

Date of March 1 and September 1 (whether or not a Business Day), as the case may be, until the principal thereof is paid or made available for payment. Interest on the Notes will be calculated on the basis of a 360-day year comprised of
twelve 30-day months. 
 If any Interest Payment Date, Redemption Date, Change of Control Payment Date or Maturity date is not a
Business Day, the payment of principal and interest, as applicable, will be made on the next succeeding Business Day. No interest will accrue on the amount so payable for the period from any Interest Payment Date, Redemption Date, Change of Control
Payment Date or the Maturity date, as the case may be, to the date payment is made on such next succeeding Business Day. 
 2. METHOD OF PAYMENT

 Subject to the terms and conditions of the Indenture, the Company shall make payments in respect of the Notes to the Persons
who are registered Holders of Notes as of the close of business on the Business Day preceding the Redemption Date or Maturity date, as the case may be, or at the close of business on a Change of Control Payment Date. Holders must surrender Notes to
a Paying Agent to collect such payments in respect of the Notes. The Company shall pay cash amounts in money of the United States that at the time of payment is legal tender for payment of public and private debts. However, the Company may make such
cash payments by check payable in such money. 
 3. PAYING AGENT AND SECURITY REGISTRAR 

Initially, U.S. Bank National Association, a national banking association under the laws of the United States of America and having a
corporate trust office in Atlanta, Georgia (the “Trustee”), shall act as Paying Agent and Security Registrar. The Company may appoint and change any Paying Agent and Security Registrar or co-registrar without notice, other than
notice to the Trustee except that the Company will maintain at least one Paying Agent in the State of New York, City of New York, Borough of Manhattan. The Company or any of its Subsidiaries or any of their Affiliates may act as Paying Agent,
Security Registrar or co-registrar. 







 4. INDENTURE 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under a Senior Debt Indenture,
dated as of March 2, 2012 (the “Base Indenture”), as supplemented by the First Supplemental Indenture thereto, dated as of March 2, 2012 (the “Supplemental Indenture” and, together with the Base Indenture,
the “Indenture”), between the Company and the Trustee. Capitalized terms used herein and not defined herein have the meanings ascribed thereto in the Indenture. Reference is hereby made to the Indenture for a statement of the
respective rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which the Notes are to be authenticated and delivered. The terms, conditions and provisions of the Notes are those stated in the Indenture,

5. REDEMPTION AT THE OPTION OF THE COMPANY 
 No sinking fund is provided for the Notes. Except as set forth below, the Notes shall not be redeemable by the Company. 
 The Company, at its option, may at any time or from time to time redeem the Notes in whole or in part at a redemption price equal to the greater of (1) 100% of the principal amount of the Notes to be
redeemed and (2) the sum of the present values of the Remaining Scheduled Payments on such Notes discounted to the date of redemption, on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months), at a rate equal to the
sum of the applicable Treasury Rate, plus 35 basis points, plus in either case accrued and unpaid interest thereon to, but excluding, the Redemption Date. 
 6. NOTICE OF REDEMPTION AT THE OPTION OF THE COMPANY 
 Subject to the provisions of
paragraph 5 of this Note, at least 30 days but not more than 60 days before a Redemption Date, the Company shall mail or cause to be mailed a notice of redemption by first-class mail to the Trustee, the Paying Agent and each Holder of Notes to be
redeemed at such Holder’s address as it appears on the Note register or otherwise in accordance with DTC’s procedures. If money sufficient to pay the Redemption Price of all Notes (or portions thereof) to be redeemed on the Redemption Date
is deposited with the Paying Agent prior to or on the Redemption Date, on and after the Redemption Date, interest, if any, shall cease to accrue on such Notes or portions thereof. Notes in denominations larger than $2,000 Principal Amount may be
redeemed in part but only in integral multiples of $1,000 Principal Amount in excess thereof. 
 7. REPURCHASE OF NOTES AT THE OPTION OF THE
HOLDER UPON A CHANGE OF CONTROL REPURCHASE EVENT 
 If a Change of Control Repurchase Event occurs, each Holder shall 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 Notes pursuant to a Change of Control Offer on the terms set forth in the Indenture. In the Change of Control Offer, the Company will offer payment
in cash equal to not less than 101% of the aggregate principal amount of Notes repurchased plus accrued and unpaid interest to, but excluding the date of repurchase, which date will be no earlier than the date of the Change of Control. The Company
shall not be required to make a Change of Control Offer upon a Change of Control Repurchase Event 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
Section 2.04 of the Supplemental Indenture applicable to a Change of Control Offer made by the Company and purchases all Notes validly tendered and not withdrawn under such Change of Control Offer. 

8. RANKING 
 The Notes shall be
direct senior obligations of the Company and shall rank senior in right of payment to all existing and future Indebtedness that is, by its terms, expressly subordinated in right of payment to the Notes and pari passu in right of payment with
all other unsecured senior Indebtedness of the Company. The Notes are not guaranteed. 
 9. DEFAULTED INTEREST 

Except as otherwise specified with respect to the Notes, any Defaulted Interest on any Note shall forthwith cease to be payable to the
registered Holder thereof on the relevant Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company as provided for in Section 2.08 of the Base Indenture and Section 2.02 of the
Supplemental Indenture. 
 10. DENOMINATIONS; TRANSFER; EXCHANGE 
 The Notes are in registered form, without coupons, in denominations of $2,000 or integral multiples of $1,000 in excess thereof. A Holder may transfer Notes in accordance with the Indenture. The Security
Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. In the event of a partial redemption of the Notes or Change
of Control Offer, the Security Registrar need not transfer or exchange any Notes selected for redemption (except, in the case of a Note to be redeemed in part, the portion of the Note not to be redeemed), or any Notes tendered and not withdrawn in
connection with a Change of Control Offer (except, in the case of a Note to be repurchased in part, the portion of the Note not to be repurchased), for a period of 15 days before the mailing of a notice with respect to a redemption or Change of
Control Offer, as applicable, and ending at the close of business on the day of such mailing. The Notes are subject to certain transfer restrictions set forth in Article 3 of the Supplemental Indenture.

registered Holder of this Note may be treated as the owner of this Note for all purposes. 
 12. UNCLAIMED MONEY OR PROPERTY 







 The Trustee and the Paying Agent shall return to the Company upon written request any money
or property held by them for the payment of any amount with respect to the Notes that remains unclaimed for one year; provided, however, that the Trustee or such Paying Agent, before being required to make any such return, shall at the
expense of the Company cause to be published once in a newspaper of general circulation in The City of New York or mail to each such Holder notice that such money or property remains unclaimed and that, after a date specified therein, which shall
not be less than 30 days from the date of such publication or mailing, any unclaimed money or property then remaining shall be returned to the Company. After return to the Company, Holders entitled to the money or property must look to the
Company for payment as general creditors unless an applicable abandoned property law designates another Person.

consent of the Holders of at least a majority in aggregate Principal Amount of the Notes at the time outstanding and (ii) certain Defaults or noncompliance with certain provisions may be waived with the written consent of the Holders of a

14. DEFAULTS AND REMEDIES 
 If
an Event of Default occurs and is continuing, the Trustee, or the Holders of at least 25% in aggregate Principal Amount of the Notes at the time outstanding, may declare the outstanding Principal Amount and any accrued and unpaid interest, of all
the Notes to be due and payable immediately. Certain events of bankruptcy or insolvency are Events of Default which shall result in the Notes being declared due and payable immediately upon the occurrence of such Events of Default. 

Events of Default in respect of the Notes are set forth in Section 4.01 of the Base Indenture, as amended and supplemented by
Article 4 of the Supplemental Indenture. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may refuse to enforce the Indenture or the Notes unless it receives indemnity or security reasonably
satisfactory to it. Subject to certain limitations, conditions and exceptions, Holders of a majority in aggregate Principal Amount of the Notes at the time outstanding may direct the Trustee in its exercise of any trust or power, including the
annulment of a declaration of acceleration. The Trustee may withhold from Holders notice of any continuing Default (except a Default in payment of amounts specified in clauses (1) and (2) of Section 4.01 of the Base Indenture) if it
determines that withholding notice is in their interests. 
 15. CONSOLIDATION, MERGER, AND SALE OF ASSETS 

In the event of a consolidation, merger, or sale of assets to convey, transfer or lease of all or substantially all of the Company’s
property or assets as described in Section 7.01 of the Base Indenture, the successor corporation to the Company shall succeed to and be 







 
substituted for the Company, and may exercise the Company’s rights and powers under the Indenture, and thereafter, except in the case of a lease, the Company shall be relieved of all
obligations and covenants under the Indenture and the Notes with respect to its obligations under the Indenture. 
 16. TRUSTEE AND AGENT
DEALINGS WITH THE COMPANY 
 The Trustee, Paying Agent and Security Registrar under the Indenture, each in its individual or any
other capacity, may become the owner or pledgee of Notes and may otherwise deal with and collect obligations owed to it by the Company or its Affiliates and may otherwise deal with the Company or its Affiliates with the same rights it would have if
it were not Trustee, Paying Agent or Security Registrar. 
 17. NO RECOURSE AGAINST OTHERS 

A director, officer or employee, as such, of the Company or any Subsidiary of the Company or any stockholder as such, of the Company shall
not have any liability for any obligations of the Company under the Notes or the Supplemental Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. By accepting a Note, each Holder waives and releases
all such liability. The waiver and release are part of the consideration for the issue of the Notes.

This Note shall not be valid until an authorized officer of the Trustee or Authenticating Agent manually signs the Trustee’s
certificate of authentication on the other side of this Note.
