REVERSE OF SECURITY

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 an Indenture, dated as of May 18, 2009 (herein called the “Indenture”), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which the Indenture and all indentures supplemental thereto (including as supplemented by an Officers’ Certificate pursuant 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 hereof.

The Company may redeem some or all of the Securities of this series upon not less than 30 days’ but no more than 60 days’ notice by mail or electronic delivery (or otherwise by transmission in accordance with the Depository’s procedures), at any time and from time to time prior to June 15, 2028 (the “Par Call Date”), at the election of the Company, at a Redemption Price equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 10 basis points less (b) interest accrued to the Redemption Date, and (2) 100% of the then-outstanding principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date. Nonetheless, interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.

On or after the Par Call Date, the Company may redeem the Securities, in whole or in part, upon not less than 30 days’ but no more than 60 days’ notice by mail or electronic delivery (or otherwise by transmission in accordance with the Depository’s procedures), at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

If (i) the consummation of the Encino Acquisition does not occur on or before the later of (a) May 30, 2026 and (b) the date that is five Business Days after the date to which the outside date under the Purchase Agreement may be extended (such later date, the “Outside Date”), (ii) prior to the Outside Date, the Purchase Agreement is terminated or (iii) the Company otherwise notifies the Trustee in writing that the Company will not pursue the consummation of the Encino Acquisition (the earlier of the date of delivery of such notice described in clause (iii), the Outside Date and the date the Purchase Agreement is terminated, the “Special Mandatory Redemption Trigger Date”), the Company will be required to redeem the Securities (such redemption, the “Special Mandatory Redemption”), at a special mandatory Redemption Price equal to 101% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest to, but excluding, the Special Mandatory Redemption Date (as defined below) (the “Special Mandatory Redemption Price”).

In the event that the Company becomes obligated to redeem the Securities pursuant to the Special Mandatory Redemption, the Company will promptly, and in any event not more than five Business Days after the Special Mandatory Redemption Trigger Date, deliver written notice to the Trustee of the Special Mandatory Redemption and the date upon which the Securities will be redeemed (the “Special Mandatory Redemption Date,” which date shall be no earlier than the third Business Day and no later than 30 days following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each registered holder of Securities to be redeemed. The Trustee will then promptly mail or deliver electronically if the Securities are held by any Depository (including, without limitation, DTC) in accordance with such Depository’s customary procedures, such notice of Special Mandatory Redemption to each registered holder of Securities to be redeemed at its registered address. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Securities to be redeemed.

Upon the closing of the Encino Acquisition, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

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 portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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

The Indenture 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 more than 50% in principal amount of the Securities at the time Outstanding of all 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Company on this Security upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall, without the consent of the Holder, alter or impair the right of the Holder, which is absolute and unconditional, to receive payment of principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed, except for Section 113 of the Indenture (which limits interest to the maximum amount permissible by law), the provisions of which are incorporated herein by reference.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable 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 his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities 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. 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 of a different authorized denomination, as requested by the Holder surrendering the same.

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

All terms used in this Security which are defined in the Indenture shall have the meanings assigned to them in the Indenture (including as the Indenture is supplemented by the Officers’ Certificate, dated July 1, 2025, establishing the form and terms of the Securities of this series).

REVERSE OF SECURITY

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 an Indenture, dated as of May 18, 2009 (herein called the “Indenture”), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture), to which the Indenture and all indentures supplemental thereto (including as supplemented by an Officers’ Certificate pursuant 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 hereof.

The Company may redeem some or all of the Securities of this series upon not less than 30 days’ but no more than 60 days’ notice by mail or electronic delivery (or otherwise by transmission in accordance with the Depository’s procedures), at any time and from time to time prior to January 15, 2055 (the “Par Call Date”), at the election of the Company, at a Redemption Price equal to the greater of (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date, and (2) 100% of the then-outstanding principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest thereon to the Redemption Date. Nonetheless, interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture.

On or after the Par Call Date, the Company may redeem the Securities, in whole or in part, upon not less than 30 days’ but no more than 60 days’ notice by mail or electronic delivery (or otherwise by transmission in accordance with the Depository’s procedures), at any time and from time to time, at a Redemption Price equal to 100% of the principal amount of the Securities being redeemed plus accrued and unpaid interest thereon to the Redemption Date.

If (i) the consummation of the Encino Acquisition does not occur on or before the later of (a) May 30, 2026 and (b) the date that is five Business Days after the date to which the outside date under the Purchase Agreement may be extended (such later date, the “Outside Date”), (ii) prior to the Outside Date, the Purchase Agreement is terminated or (iii) the Company otherwise notifies the Trustee in writing that the Company will not pursue the consummation of the Encino Acquisition (the earlier of the date of delivery of such notice described in clause (iii), the Outside Date and the date the Purchase Agreement is terminated, the “Special Mandatory Redemption Trigger Date”), the Company will be required to redeem the Securities (such redemption, the “Special Mandatory Redemption”), at a special mandatory Redemption Price equal to 101% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest to, but excluding, the Special Mandatory Redemption Date (as defined below) (the “Special Mandatory Redemption Price”).

In the event that the Company becomes obligated to redeem the Securities pursuant to the Special Mandatory Redemption, the Company will promptly, and in any event not more than five Business Days after the Special Mandatory Redemption Trigger Date, deliver written notice to the Trustee of the Special Mandatory Redemption and the date upon which the Securities will be redeemed (the “Special Mandatory Redemption Date,” which date shall be no earlier than the third Business Day and no later than 30 days following the date of such notice) together with a notice of Special Mandatory Redemption for the Trustee to deliver to each registered holder of Securities to be redeemed. The Trustee will then promptly mail or deliver electronically if the Securities are held by any Depository (including, without limitation, DTC) in accordance with such Depository’s customary procedures, such notice of Special Mandatory Redemption to each registered holder of Securities to be redeemed at its registered address. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Securities to be redeemed.

Upon the closing of the Encino Acquisition, the foregoing provisions regarding the Special Mandatory Redemption will cease to apply.

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 portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof.

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

The Indenture 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 more than 50% in principal amount of the Securities at the time Outstanding of all 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 herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Company on this Security upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Security.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall, without the consent of the Holder, alter or impair the right of the Holder, which is absolute and unconditional, to receive payment of principal of and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed, except for Section 113 of the Indenture (which limits interest to the maximum amount permissible by law), the provisions of which are incorporated herein by reference.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registerable 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 his attorney duly authorized in writing, and thereupon one or more new Securities of this series, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Securities 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. 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 of a different authorized denomination, as requested by the Holder surrendering the same.

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