 ARTICLE TWO 

GENERAL TERMS AND CONDITIONS OF THE NOTES 

Section 2.01 Designation and Principal Amount. 

The Notes are hereby authorized and are designated as a Series of Securities under the Base Indenture, titled as the “4.400% Senior Notes
due 2027”, initially limited to $375,000,000 in aggregate principal amount. The Notes issued on the date hereof pursuant to the terms of the Indenture shall be in an aggregate principal amount of $375,000,000, which amount shall be set forth in
the written order of the Company for the authentication and delivery of the Notes pursuant to Section 2.3 of the Base Indenture. 
 In
addition, without the consent of the Holders of the Notes, the Company may issue Additional Notes having the same terms (except for the issue date and, in some cases, the public offering price and the first interest payment date) as, and ranking
equally and ratably with, the Notes. Any Additional Notes, will constitute a single series of Notes under the Indenture. No Additional Notes may be issued if an Event of Default under the Indenture has occurred and is continuing with respect to the
Notes. 
 Section 2.02 Maturity. 

Unless an earlier redemption has occurred, the principal amount of the Notes shall mature and be due and payable, together with any accrued
interest thereon, on March 15, 2027 (the “Maturity Date”). 
 Section 2.03 Form and Payment. 

The Notes shall be issued as global notes, in fully registered book-entry form without coupons in minimum denominations of $2,000 and integral
multiples of $1,000 in excess thereof. 
 The Notes and the Trustee’s Certificates of Authentication to be endorsed thereon are to be
substantially in the form of Exhibit A, which form is hereby incorporated in and made a part of this Supplemental Indenture. 
 The
terms and provisions contained in the Notes shall constitute, and are hereby expressly made, a part of this Supplemental Indenture, and the Company and the Trustee, by their execution and delivery of this Supplemental Indenture, expressly agree to
such terms and provisions and to be bound thereby. 
 The Company will make payments of principal and/or interest, if any, in respect of the
Notes represented by global notes by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company (together with any successor thereto, the “Depositary”) or its nominee. The Company will
make all payments of principal, premium, if any, and/or interest and special interest, if any, with respect to certificated notes by wire transfer of immediately available funds to the accounts specified by the Holders of the certificated notes or,
if no such account is specified, by mailing a check to each such Holder’s registered address. 

  
 4 








 Principal, premium, if any, and/or interest, if any, on the global notes representing the Notes
shall be made to the Depositary. 
 The global notes representing the Notes shall be deposited with, or on behalf of, the Depositary and
shall be registered in the name of the Depositary or a nominee of the Depositary. No global note may be transferred except as a whole by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or
such nominee to a successor of the Depositary or a nominee of such successor. 
 If any Interest Payment Date or the Maturity Date is not a
Business Day, the related payment of principal of or interest on such series of Notes shall become due and payable on the next succeeding Business Day with the same force and effect as if made on the date such payment were due, and no interest shall
accrue on the amount payable for the period from and after such Interest Payment Date or the Maturity Date, as the case may be. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such
regular Record Date and shall be paid as set forth in Section 2.13 of the Base Indenture. 
 Section 2.04 Interest.

 Interest on the Notes shall accrue at the rate of 4.400% per annum. Interest on the Notes shall accrue from September 15, 2017 or the
most recent Interest Payment Date on which interest was paid. Interest on the Notes shall be payable semi-annually in arrears on March 15 and September 15 of each year, beginning on September 15, 2017 (each an “Interest
Payment Date”), to the Holders in whose names the Notes are registered at the close of business on the preceding March 1 and September 1 (each a “Record Date”). Interest on the Notes shall be computed on the basis of a
360-day year comprised of twelve 30-day months. 
 Section 2.05 Limitation on Liens. 

So long as any Notes are outstanding, the Company will not, and will not permit any of its Principal Subsidiaries to, directly or indirectly,
use any voting stock of a Principal Subsidiary as security for any of its debt or other obligations unless the Notes are secured prior to, or to the same extent as that debt or other obligation. This restriction does not apply to liens on voting
stock existing at the time a corporation becomes the Company’s Principal Subsidiary or any renewal or extension of such existing liens and does not apply to shares of Subsidiaries that are not “Principal Subsidiaries.” 

Section 2.06 Limitation on Disposition of Stock of Principal Subsidiaries. 

The Company will not, and will not permit any of its Subsidiaries to, issue, sell, assign, transfer or otherwise dispose of, directly or
indirectly, any of the common stock of the Company’s Principal Subsidiaries (except to the Company or to one or more of the Company’s other Subsidiaries or for the purpose of qualifying directors), except for: 

 

	 	(a)	any issuance, sale, assignment, transfer or other disposition is required to comply with the order of a court or regulatory authority of competent jurisdiction, other than an order issued at the Company’s request
or at the request of one of the Company’s Subsidiaries; 


  
 5 









	 	(b)	all of the common stock of a principal subsidiary owned by the Company or by a Principal Subsidiary sold for cash or other property having a fair market value that is at least equal to the fair market value of the
disposed stock, as determined in good faith by the Company’s board of directors; or 

  

	 	(c)	after giving effect to the issuance, sale, assignment, transfer or other disposition, the Company and its Subsidiaries would own directly or indirectly at least 80% of the issued and outstanding common stock of such
principal subsidiary and such issuance, sale, assignment, transfer or other disposition is made for consideration consisting of cash or other property which is at least equal to the fair value of such common stock.

shares of capital stock of which the Company owns at least 80%.

(2) the sum of the present values of the remaining scheduled payments of principal and interest on any Notes to be redeemed

or after the Par Call Date, the Notes may be redeemed, in whole or in part, at the Company’s option, at any time or from time to time, on notice given not more than 60 days, nor less than 30 days, prior to the Redemption Date, at a Redemption

(b) the Redemption Date; 
 (c) the

 If the Company chooses to redeem less than all of the Notes, the Company will notify the Trustee
at least 60 days before giving the Redemption Notice, or such shorter period as is satisfactory to the Trustee, of the aggregate principal amount of the Notes to be redeemed and the applicable Redemption Date. If less than all of the Notes are to be

to accrue on any Notes that have been called for redemption at the Redemption Date. 
 At the Company’s written request, the Trustee
shall give the Redemption Notice in the Company’s name and at its expense; provided, however, that the Company has delivered to the Trustee, at least 10 days prior to the Redemption Date, an Officers’ Certificate requesting
that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

business 30 days immediately preceding the sending of a Redemption Notice of Notes selected for redemption and ending at the close of business on the day of such notice is sent (ii) to register the transfer of or exchange any Notes between a
Record Date and the related Interest Payment Date, or (iii) to register the transfer of or exchange any Notes selected, called or being called for redemption in whole or in part.
