This Note is one of the series designated on the face hereof initially limited in aggregate principal amount to $1,000,000,000; provided, however, that the Company may from time to time, without the consent of the Holders, issue Additional Notes having the same ranking and the same interest rate, Maturity and other terms as the Initial Notes (except for any difference in the issue price and the payment of interest accruing prior to the issue date of such Additional Notes, or, in some cases, the first Interest Payment Date following the issue of such Additional Notes), and with the same CUSIP number as the Initial Notes; provided that if any Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, such Additional Notes shall have a separate CUSIP number. Any Additional Notes and the Initial Notes shall constitute a single series under the Indenture and all references to the Notes shall include the Initial Notes and any Additional Notes, unless the context otherwise requires. The aggregate principal amount of the Additional Notes shall be unlimited. No Additional Notes may be issued if any Event of Default has occurred and is continuing. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling.

On or after February 15, 2024, the Company may redeem the Notes, at its option in whole or in part, at any time and from time to time, at the redemption prices (expressed as percentages of principal amount) set forth below, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date (subject to the rights of Holders of record on relevant Regular Record Dates to receive interest due on an Interest Payment Date falling on or prior to the Redemption Date), if redeemed during the twelve month period beginning on February 15 of the years indicated below:

At any time prior to February 15, 2024, the Company may redeem the Notes, at its option in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount thereof plus the Applicable Premium as of, and accrued and unpaid interest thereon, if any, to, but excluding, the Redemption Date (subject to the rights of Holders of record on relevant Regular Record Dates to receive interest due on an Interest Payment Date falling on or prior to the Redemption Date).

At any time prior to February 15, 2024, the Company may redeem up to 35% of the original aggregate principal amount of the Notes (including any Additional Notes), at its option at any time and from time to time, at a redemption price of 104.250% of the principal amount thereof, plus accrued and unpaid interest thereon to, but excluding, the Redemption Date (subject to the rights of Holders of record on relevant Regular Record Dates to receive interest due on an Interest Payment Date falling on or prior to the Redemption Date), with the proceeds of one or more Qualified Equity Offerings; provided that (i) after giving effect to such redemption, at least 65% of the original aggregate principal amount of the Notes (including any Additional Notes) remains outstanding (excluding, for purposes of such calculation, Notes held by the Company or its Subsidiaries); and (ii) the redemption must occur within 90 days of the date of the closing of such Qualified Equity Offering.

In the event of redemption of this Note in part only, a new Note or 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.

This Note does not have the benefit of any sinking fund obligations.

If an Event of Default with respect to the Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

The defeasance provisions contained in Article Fifteen of the Indenture shall apply to this Note, provided that the Company may only exercise the defeasance or covenant defeasance options applicable to Sections 1502 or 1503 of the Indenture if the Company exercises such options with respect to all Outstanding Notes as of the date of such exercise.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company, the Guarantors and the rights of the Holders of the Notes of each series to be affected under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of the Holders of a majority in principal amount of the Notes 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 Notes of each series at the time Outstanding, on behalf of the Holders of all Notes 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 Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes of this series, the Holders of not less than 25% in principal amount of the Notes of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in

A-6

respect of such Event of Default as Trustee and offered the Trustee indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Notes of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Note 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 interest on this Note at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered and this Note may be exchanged as provided in the Indenture.

The Notes of this series are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Company, the Guarantors, the Trustee nor any such agent shall be affected by notice to the contrary.
