- 6 -

     4.2 (a) No action has been or will be taken in any jurisdiction outside the United States by the Company that would permit an offering of the Common Stock, or
possession or distribution of offering materials in connection with the issue of the Common Stock in any jurisdiction outside the United States where action for that purpose is required, (b) if the Investor is outside the United States, it will
comply with all applicable laws and regulations in each foreign jurisdiction in which it purchases, offers, sells or delivers Common Stock or has in its possession or distributes any offering material, in all cases at its own expense and (c) the
Company has not made any representation, warranty, disclosure or use of any information in connection with the issue, purchase and sale of the Common Stock, except as set forth or incorporated by reference in the Base Prospectus, Preliminary
Prospectus Supplement (if any) or the Prospectus Supplement. 

     4.3 (a) The Investor has full right, power, authority and capacity to enter into this Agreement and to consummate the transactions contemplated hereby and has taken
all necessary action to authorize the execution, delivery and performance of this Agreement, and (b) this Agreement constitutes a valid and binding obligation of the Investor enforceable against the Investor in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting creditors’ and contracting parties’ rights generally and except as enforceability may be subject to general principles
of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law) and except as to the enforceability of any rights to indemnification or contribution that may be violative of the public policy underlying any
law, rule or regulation (including any federal or state securities law, rule or regulation).

its purchase of the Common Stock.

     4.5 Since the date on which the Company first contacted the Investor about the Offering, the Investor has not disclosed any information regarding the Offering to any

Investor covenants that it will not disclose any information regarding the Offering to any third parties (other than its legal, accounting and other advisors) or engage in any purchases, sales or other transactions in the securities of the Company
(including Short Sales) prior to the time that the transactions contemplated by this Agreement are publicly disclosed.  The Investor agrees that it will not use any of the Common Stock acquired pursuant to this Agreement to cover any short position
in the Common Stock if doing so would be in violation of applicable securities laws. For purposes hereof, “Short Sales” include, without limitation, all “short sales” as

this Agreement.

the Company shall deposit with the Paying Agent money sufficient to pay the redemption price of and accrued interest on the 2020 Notes to be redeemed on such date. If the Company is redeeming less than all of the 2020 Notes, the Trustee shall select
the 2020 Notes to be redeemed by such method as the Trustee deems fair and appropriate in accordance with methods generally used at the time of selection by fiduciaries in similar circumstances. 

In the event of redemption of this 2020 Note in part only, a new 2020 Note or 2020 Notes of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 Upon the occurrence
of a Change of Control Triggering Event, unless the Company has exercised its right to redeem the 2020 Notes as described above by giving irrevocable notice to the trustee in accordance with the Indenture, each Holder of 2020 Notes shall have the
right to require the Company to purchase all or a portion of such Holder’s 2020 Notes pursuant to the offer described below (the “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus
accrued and unpaid interest, if any, to the date of purchase (the “Change of Control Payment”), subject to the rights of Holders of 2020 Notes on the relevant record date to receive interest due on the relevant interest payment
date. 
 Unless the Company has exercised its right to redeem the 2020 Notes, within 30 days following the date upon which the
Change of Control Triggering Event occurred with respect to 

 
the 2020 Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall be required to send, by first
class mail, a notice to each Holder of 2020 Notes, with a copy to the Trustee, which notice shall govern the terms of the Change of Control Offer. Such notice shall state, among other things, the purchase date, which must be no earlier than 30 days
nor later than 60 days from the date such notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, shall state
that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date. 

On the Change of Control Payment Date, the Company shall, to the extent lawful: (i) accept or cause a third party to accept for
payment all 2020 Notes or portions of 2020 Notes properly tendered pursuant to the Change of Control Offer; (ii) deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment in respect of all
2020 Notes or portions of 2020 Notes properly tendered; and (iii) deliver or cause to be delivered to the Trustee the 2020 Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of 2020 Notes
or portions of 2020 Notes being repurchased and that all conditions precedent to the Change of Control Offer and to the repurchase by the Company of 2020 Notes pursuant to the Change of Control Offer have been complied with. 

The Company shall not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and
otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all 2020 Notes properly tendered and not withdrawn under its offer. 

The Company will comply in all material respects with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as
amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the 2020 Notes as a result of a Change of Control
Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the 2020 Notes, the Company will comply with the applicable securities laws and regulations and
will not be deemed to have breached its obligations under the Change of Control Offer provisions of the 2020 Notes by virtue of such conflict. 

“Change of Control” means the occurrence of any of the following after the date of issuance of the 2020 Notes:

 (a) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or
consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and the Company’s Subsidiaries taken as a whole to any “person” or “group” (as those terms are used in
Section 13(d)(3) of the Exchange Act) other than to the Company or one of the Company’s Subsidiaries; 

 (b) the consummation of any transaction (including, without limitation, any merger or
consolidation) the result of which is that any “person” or “group” (as those terms are used in Section 13(d)(3) of the Exchange Act, it being agreed that an employee of the Company or any of the Company’s Subsidiaries
for whom shares are held under an employee stock ownership, employee retirement, employee savings or similar plan and whose shares are voted in accordance with the instructions of such employee shall not be a member of a “group” (as that
term is used in Section 13(d)(3) of the Exchange Act) solely because such employee’s shares are held by a trustee under said plan) becomes the “beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act),
directly or indirectly, of Voting Stock representing more than 50% of the voting power of the Company’s outstanding Voting Stock or of the Voting Stock of any of the Company’s direct or indirect parent companies; 

(c) the Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merge with or into, the
Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock or Voting Stock of such other Person is converted into or exchanged for cash, securities or other property, other than any such
transaction where the Company’s Voting Stock outstanding immediately prior to such transaction constitutes, or is converted into or exchanged for, Voting Stock representing at least a majority of the voting power of the Voting Stock of the
surviving Person immediately after giving effect to such transaction; 
 (d) the first day on which the majority of the members
of the Board of Directors or the board of directors of any of the Company’s direct or indirect parent companies are not Continuing Directors; or 

(e) the adoption of a plan relating to the liquidation or dissolution of the Company. 

Notwithstanding the foregoing, a transaction will not be deemed to involve a Change of Control solely because the Company becomes a

Voting Stock immediately prior to that transaction. 
 “Change of Control Triggering Event” means with respect
to the 2020 Notes, (i) the rating of such 2020 Notes is lowered by each of the Rating Agencies on any date during the period (the “Trigger Period”) commencing on the earlier of (a) the occurrence of a Change of Control and
(b) the first public announcement by the Company of any Change of Control (or pending Change of Control), and ending 60 days following consummation of such Change of Control (which Trigger Period will be extended following consummation of a
Change of Control for so long as any of the Rating Agencies has publicly announced that it is considering a possible ratings change), and (ii) such 2020 Notes are rated below Investment Grade by each of the Rating Agencies on any day during the
Trigger Period; provided that a Change of Control Trigger Event will not be deemed to have occurred in respect of a particular Change of Control if each Rating Agency making the reduction in rating does not publicly announce or confirm or
inform the trustee at the Company’s request that the reduction was the result, in whole or in part, 

 
of any event or circumstance comprised of or arising as a result of, or in respect of, the Change of Control. 

Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular
Change of Control unless and until such Change of Control has actually been consummated.

of a proxy statement in which such member was named as a nominee for election as a director). 
 “Investment
Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category of Moody’s) and a rating of BBB- or better by S&P (or its equivalent under any successor rating category of S&P),

the payment of interest accruing prior to the issue date of such additional 2020 Notes and the first payment of interest following the issue date of such additional 2020 Notes), provided that such 2020 Notes must be part of the same issue as

The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the outstanding 2020 Notes,

any of the 2020 Notes or in respect of a covenant or other provision which, under the terms of the Indenture, cannot be modified or amended without the consent of the Holder of each outstanding 2020 Note. Any such consent or waiver by the registered
