Redemption Price.

Redemption pursuant to this Section 302. The Special Optional Redemption Notice shall be mailed, with a copy to the Trustee, promptly after the occurrence of the event triggering such Special Optional Redemption to each Holder of Notes at such
Holder’s registered address. At the Company’s request, the Special Optional Redemption Notice may be given by the Trustee in the name and at the expense of the Company.

in excess thereof) of that Holder’s Notes. In the Change of Control Offer, the Company shall be required to offer payment in cash equal to 101.000% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest
thereon, if any, on the Notes repurchased to the date of repurchase (the “Change of Control Payment”). Within thirty (30) days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of
Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be mailed to the Holders of the Notes describing the transaction that constitutes or may constitute the Change of
Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than thirty (30) days and no later than sixty (60) days from the date such notice is mailed (the “Change
of Control Payment Date”). The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of
Control Payment Date. 
 On the Change of Control Payment Date, the Company shall, to the extent lawful: 

(1)    accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of
Control Offer; 
 (2)    deposit with the Paying Agent an amount equal to the Change of Control Payment
in respect of all Notes or portions of Notes properly tendered; and 
 (3)    deliver or cause to be
delivered to the Trustee the Notes properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes or portions of Notes being repurchased. 

(b)    The Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control
Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the third party repurchases all Notes properly tendered and not withdrawn under
its offer. In addition, the Company shall not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control
Payment upon a Change of Control Triggering Event. 
 (c)    The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of
Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the 

  
 8 








 
Change of Control Offer provisions of the Notes, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of
Control Offer provisions of the Notes by virtue of any such conflict. 
 ARTICLE 5

Section 5.01    Additional Interest. 
 The Company shall pay all Additional Interest, if any, in the
same manner as provided in Section 307 of the Existing Indenture on the dates and in the amounts set forth in the Registration Rights Agreement. If Additional Interest is payable on the Notes, the Company shall provide an Officers’
Certificate to the Trustee on or before the record date for each interest payment date such Additional Interest is payable setting forth the accrual period and the amount of such Additional Interest in reasonable detail. The Trustee may provide a
copy of such Officers’ Certificate or other notice received from the Company relating to Additional Interest to any Holder upon request. Unless and until a Responsible Officer of the Trustee receives at the Corporate Trust Office such a
certificate, the Trustee may assume without inquiry that no such Additional Interest is payable. If the Company has paid Additional Interest directly to the Persons entitled to it, the Company shall deliver to the Trustee an Officers’
Certificate setting forth the particulars of such payment. 
 ARTICLE 6 

AMENDMENT OF EXISTING INDENTURE 
 
Section 6.01    Amendment of Article Ten of the Existing Indenture. 
 Section 1007 of the Existing
Indenture is hereby amended and restated, but only with respect to the Notes, to read in its entirety as follows:

upon any Principal Property, or upon any shares of stock of any Principal Subsidiary of the Company (whether such Principal Property or shares are owned as of the Issue Date or thereafter acquired), to secure any Debt without making, or causing such
Principal Subsidiary to make, effective provision for securing the Securities (and no other indebtedness of the Company or any Principal Subsidiary of the Company except, if the Company shall so determine, any other indebtedness of the Company which
is not subordinate in right of payment to the Securities or of such Principal Subsidiary) (x) equally and ratably with such Debt as to such Principal Property or shares for as long as such Debt shall be so secured unless such Debt is Debt of

The foregoing restrictions will not apply to Liens existing at the Issue Date or to: 

(i) Liens securing only the Securities; 

(ii) Liens in favor of only the Company; 

  
 9 








 (iii) Liens on property of a Person existing at the time such Person is merged
into or consolidated with the Company or any Principal Subsidiary of the Company (but only to the extent such Liens cover such property); 

(iv) Liens on property existing immediately prior to the time of acquisition thereof (and not in anticipation of the financing
of such acquisition);

Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the Trustee, together with:

1.    General.

collectively herein called the “Indenture”; all capitalized terms used and not defined herein shall have the meanings assigned to them in the Indenture), between the Company and U.S. Bank National Association, as trustee (herein
called the “Trustee,” which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights,
duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face

outstanding. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the
obligation of the Company, which is absolute and unconditional, to pay the principal of, and any premium and any interest on, this Security at the place and rate, and in the coin or currency, herein prescribed. 

2.    Redemption. 

(a)    At any time and from time to time, prior to April 15, 2021, the Securities may be redeemed in whole or in part

Section 307 of the Indenture). 
 (b)    At any time and from time to time, prior to April 15, 2021, up to 40%
in aggregate principal amount of the Securities may be redeemed, at the sole election of the Company, at a Redemption Price equal to 105.750% of the principal amount thereof (the “Equity Redemption Price”), plus accrued and unpaid interest
thereon, if any, to, but not including, the relevant Redemption Date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date falling prior to or on the Redemption
Date pursuant to Section 307 of the Indenture), with the net cash proceeds of one or more Equity Offerings; provided that (1) immediately after the occurrence of such redemption, to at least 60% of the aggregate principal amount of
Notes originally issued under the Third Supplemental Indenture (excluding Securities held by the Company or its Subsidiaries) remain outstanding, and (2) such redemption occurs within ninety (90) days of the date of the closing of such
Equity Offering.

 Notice of any redemption shall be mailed at least thirty (30) days but not more than sixty (60) days
prior to the Redemption Date to each Holder of the Securities to be redeemed at its registered address. In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed

or may constitute the Change of Control, a notice will be mailed to the Holders of the Securities describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase the Securities on the
Change of Control Payment Date specified in the notice, which date will be no earlier than thirty (30) days and no later than sixty (60) days from the date such notice is mailed. The notice will, if mailed prior to the date of consummation

payable in the manner and with the effect provided in the Indenture. 
 8.    Sinking Fund. 

The Securities will not be subject to any sinking fund. 

9.    Denominations; Transfer; Exchange. 

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security
Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more Securities of this series and of
like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

The Securities are issuable only in fully registered form without coupons in denominations of $2,000 and any integral multiple of $1,000 in
excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of a different
authorized denomination, as requested by the Holder surrendering the same. 
 No service charge shall be assessed against the Holder for any
such registration of transfer or exchange, but the Company may require from the Holder payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

The Company, together with the Trustee, may modify the Indenture or the Securities, without the consent of the Holders of any Outstanding
Securities, for certain specified purposes, including, among other things, adding to the Company’s covenants or events of default, securing the Securities, appointing a substitute trustee, curing ambiguities, defects or inconsistencies,
maintaining the qualification of the Indenture under the Trust Indenture Act, as amended, providing for the assumption by a successor to the Company of its obligations under the Indenture and making any change that does not adversely affect the
interests of the Holders of Securities of any series in any material respect. 
 The Indenture also permits, with certain exceptions as
therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee
with the consent of the Holders of not less than a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in
principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer
hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

12.    No Personal Liability of Directors, Officers, Employees and Stockholders. 

No past, present or future director, officer, employee, incorporator, agent, member or stockholder or Affiliate of the Company, as such, shall
have any liability for any obligations of the Company under the Securities of this series, under the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder of Securities of this series by
accepting a Security of this series waives and releases all such liabilities. The waiver and release are part of the consideration for issuance of the Securities of this series.

Defeasance. 
 The Company’s obligations pursuant to the Indenture with respect to Securities of this series will be discharged, except
for obligations pursuant to certain sections thereof, subject to the terms of the Indenture, upon the payment of all the Securities of this series or upon the irrevocable deposit with the Trustee of United States dollars or U.S. Government
