NOW, THEREFORE, in consideration of the premises and for other good and valuable consideration, the sufficiency and adequacy of which are hereby acknowledged, the parties hereto hereby agree as follows:

ARTICLE I

APPLICATION OF TWELFTH SUPPLEMENTAL INDENTURE

AND CREATION OF NOTES

Section 1.01Application of this Twelfth Supplemental Indenture.

Notwithstanding any other provision of this Twelfth Supplemental Indenture, pursuant to Section 13.01 of the Existing Indenture, the provisions of this Twelfth Supplemental Indenture, including the covenants set forth herein, are expressly being included solely for the benefit of the Holders of the Notes. The Notes comprise one series of Securities pursuant to Section 3.01 of the Existing Indenture and as provided in Section 1.02 hereof.

Section 1.02Designation and Amount of Notes.

There is hereby established a series of Securities designated the “5.250% Notes due 2028” (the “Notes”). The Notes shall be unsecured and unsubordinated obligations of the Company. The initial maximum aggregate principal amount of the Notes that may be authenticated and delivered under this Twelfth Supplemental Indenture shall not exceed $500,000,000, except for Notes authenticated and delivered upon registration or transfer of, or in exchange for, or in lieu of, Notes pursuant to Sections 3.04, 3.06, 3.07 and 4.06 of the Existing Indenture. Notwithstanding the foregoing, the Company may from time to time, without giving notice to or seeking the consent of the Holders of the Notes, issue debt securities having the same terms (except for the issue date, and, in some cases, the public offering price and the first Interest Payment Date) and ranking equally and ratably with the Notes created hereunder (the “Additional Notes”). The Notes and the Additional Notes shall together constitute one series for purposes of the Existing Indenture and this Twelfth Supplemental Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase, provided they are fungible for U.S. federal income tax purposes and that no Event of Default with respect to the Notes shall have occurred or be continuing.

Section 1.03Terms; Denominations; Form of Security.

(a)The Notes are issuable in fully registered form as Global Securities without coupons, in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000, and shall be in substantially the form of Exhibit A hereto. The Depository Trust Company (“DTC”) shall act as Depositary for the Notes. Notwithstanding the foregoing, the Notes shall be issued as Individual Securities to each Person that the Depositary identifies as the beneficial owner of the Notes represented by the Global Securities upon surrender by the Depositary of the Global Security if:

(i)the Depositary notifies us that it is no longer willing or able to act as a depositary for such Global Security or ceases to be a clearing agency registered under the

Exchange Act, and the Company shall not have appointed a successor Depositary within 90 days of that notice or becoming aware that the Depositary is no longer so registered;

(ii)an Event of Default has occurred and is continuing, and the Depositary requests the issuance of certificated notes; or

(iii)the Company determines not to have the Notes represented by a Global Security.

(b)The terms and provisions contained in the form of Note attached hereto as Exhibit A shall constitute, and are hereby expressly made, a part of this Twelfth Supplemental Indenture and the Company, by its execution and delivery of this Twelfth Supplemental Indenture, expressly agrees to such terms and provisions and to be bound thereto. Any of the Notes may have such letters, numbers or other marks of identification and such notations, legends and endorsements as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and are not inconsistent with the provisions of the Indenture (and which do not affect the rights, duties or immunities of the Trustee), or as may be required to comply with any law or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange or automated quotation system on which the Notes may be listed.

Section 1.04Payment of Principal and Interest,

(a)The Notes shall mature, and the principal of the Notes shall be due and payable in U.S. Dollars to the Holders thereof, together with all accrued and unpaid interest thereon, on January 15, 2028 (the Stated Maturity of principal of the Notes).

(b)The Notes shall bear interest at the rate of 5.250% per annum, from and including November 17, 2022, or from the most recent Interest Payment Date on which interest has been paid or provided for, until the principal thereof becomes due and payable, and on any overdue principal and premium, if any, and (to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest at the same rate per annum. Interest shall be calculated on the basis of a 360-day year comprised of twelve 30-day months. Interest on the Notes shall be payable semi-annually in arrears in U.S. Dollars on January 15 and July 15 of each year, beginning July 15, 2023 to the Person in whose name a Note (or predecessor Note) is registered (which shall initially be the Depositary) at the close of business on the January 1 or July 1, as the case may be, immediately preceding each Interest Payment Date.

(c)For so long as the Notes are represented by one or more Global Securities, all payments of principal, premium, if any, and interest shall be made by the Company through the Paying Agent by wire transfer of immediately available funds in U.S. Dollars to the Depositary or its nominee, as the case may be, as the registered owner of the Global Securities representing the Notes. In the event that definitive Notes shall have been issued, all payments of principal, premium, if any, and interest with respect to the Notes shall be made by the Company through the Paying Agent by wire transfer of immediately available funds in U.S. Dollars to the accounts of the registered Holders thereof; provided, that the Company may elect to make such payments at the office of the Paying Agent in The City of Minneapolis; and provided further, that the

Company may at its option pay interest by check to the registered address of each Holder of a definitive Note.

(d)The Notes shall trade in the Depositary’s Same-Day Funds Settlement System until Stated Maturity (or until they are subject to acceleration pursuant to Article VII of the Existing Indenture), and secondary market trading activity in the Notes may be required by the Depositary to settle in immediately available funds with respect to such Notes.

(e)The Notes are subject to redemption by the Company in whole or in part in the manner described herein.

Section 1.05Sinking Fund.

The Notes are not subject to any sinking fund.

Section 1.06Defeasance and Covenant Defeasance.

The defeasance and covenant defeasance provisions of Article XI of the Existing Indenture will apply to the Notes.

Section 1.07Tax Matters.

The Company will not pay additional amount on the Notes held by Non-U.S. Persons in respect of any tax, assessment or governmental charge withheld or deducted.

(c)The following are definitions used in this Twelfth Supplemental Indenture and to the extent that a term is defined both herein and in the Existing Indenture, the definition in this Twelfth Supplemental Indenture shall govern with respect to the Notes.

“Attributable Debt” in respect of a Sale and Leaseback Transaction means, as of any particular time, the present value (discounted at the rate of interest implicit in the terms of the lease involved in the Sale and Leaseback Transaction, as determined in good faith by the Company) of the obligation of the lessee thereunder for net rental payments (excluding, however, any amounts required to be paid by such lessee, whether or not designated as rent or additional rent, on account of maintenance and repairs, services, insurance, taxes, assessments, water rates and similar charges or any amounts required to be paid by such lessee thereunder contingent upon monetary inflation or the amount of sales, maintenance and repairs, insurance, taxes, assessments, water rates or similar charges) during the remaining term of such lease (including any period for which such lease has been extended or may, at the option of the lessor, be extended).

Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly of more than 50% of the Voting Stock of such holding company.

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15 (TCM)”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal

to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third business day preceding the Redemption Date H.15 (TCM) or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

“Unrestricted Subsidiaries” means (1) any Subsidiary substantially all of whose physical properties are located, or substantially all of whose business is carried on, outside the United States and Canada, (2) any finance Subsidiary and (3) any Subsidiary of an Unrestricted Subsidiary.

“Voting Stock” of any specified Person as of any date means the capital stock of such Person that is at the time entitled to vote generally in the election of the board of directors of such Person.

“Wholly-Owned Subsidiary” of any specified Person means a Subsidiary all of whose Voting Stock is owned by the Company or a Wholly-Owned Subsidiary, the accounts of which are consolidated with those of the Company in its consolidated financial statements.

ARTICLE III

​

OPTIONAL REDEMPTION

At any time prior to the Par Call Date, the Company may redeem the Notes, at any time in whole or from time to time in part, in each case at the Company’s option, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

plus, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date.

In addition, the Company may redeem the Notes, at any time in whole or from time to time in part, at the Company’s option, on or after the Par Call Date, in each case at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to but excluding the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders of the Notes as of the close of business on the Record Date according to the Notes and the Indenture.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each registered Holder of the Notes to be redeemed by the Company or by the Trustee on its behalf; provided that notice of redemption may be delivered more than 60 days prior to the Redemption Date if the notice is issued in connection with a defeasance of such Notes or a satisfaction and discharge of such Notes. The Company shall notify the Trustee of the Redemption Date and of the principal amount of the Notes to be

redeemed at least 45 days prior to the Redemption Date, unless a shorter period is satisfactory to the Trustee.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions thereof called for redemption.

Except as otherwise set forth in this Article III, the terms and conditions upon which and the manner in which the Notes may be redeemed by the Company pursuant to this Article III are governed by the provisions of Article IV of the Existing Indenture.

5.250% NOTES DUE 2028

1.This Note is one of a duly authorized issue of Securities of the Company designated as its 5.250% Notes due 2028 (the “Notes”) issued under an Indenture dated as of January 12, 2015 (herein called, together with the Twelfth Supplemental Indenture referred to below, the “Indenture”), between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as Trustee, to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Notes, and the terms upon which the Notes are, and are to be, authenticated and delivered.

2.This Note is one of the Securities of the series designated on the face hereof, limited to an aggregate principal amount not to exceed $500,000,000, which amount may be increased at the option of the Company if in the future it determines that it may wish to sell additional Notes of this series, as specified in the Twelfth Supplemental Indenture between the Company and Trustee, dated as of November 17, 2022, establishing the form and certain terms of the Notes pursuant to the Indenture (the “Twelfth Supplemental Indenture”).  References herein to “this series” mean the series of Notes designated on the face hereof.

3.The Company may redeem the Notes at any time in whole or from time to time in part, in each case at the Company’s option, prior to December 15, 2027 (the “Par Call Date”), at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

(i)100% of the principal amount of the Notes to be redeemed; and

(ii)(a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes to be redeemed 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 (as defined in the Twelfth Supplemental Indenture) plus 15 basis points less (b) interest accrued to the Redemption Date;

plus, in either case, accrued and unpaid interest, if any, to but excluding the Redemption Date.

In addition, the Company may redeem the Notes, at any time in whole or from time to time in part, at the Company’s option, on or after the Par Call Date, at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to but excluding the Redemption Date.

Notwithstanding the foregoing, installments of interest on the Notes that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant Record Date according to this Note and the Indenture.

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC’s procedures) at least 10 days but not more than 60 days before the Redemption Date to the registered Holder of the Notes to be redeemed.

In the case of a partial redemption, for so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original Note.

Any notice to Holders of Notes of a redemption pursuant to this paragraph 3 hereof will include the appropriate calculation of the Redemption Price, but does not need to include the Redemption Price itself.  The actual Redemption Price, calculated as described above, will be set forth in a Company Order delivered to the Trustee no later than two Business Days prior to the Redemption Date.

4.Upon the occurrence of a Change of Control Repurchase Event, unless all of the Notes have been called for redemption pursuant to paragraph 3 of this Note, each Holder of Notes shall have the right to require the Company to repurchase all or any part (equal to $1,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes at a repurchase price in cash equal to 101% of the aggregate principal amount of such Notes repurchased plus any accrued and unpaid interest on the Notes repurchased to the date of repurchase.  “Change of Control Repurchase Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event, as such terms are defined in the Indenture.  The Change of Control Offer will be made in accordance with the terms specified in the Indenture.

5.If an Event of Default with respect to the Notes (other than certain events of bankruptcy, insolvency or reorganization) shall occur and be continuing, the Trustee or the Holders of 25% or more in principal amount of the Outstanding Notes may declare the principal of and accrued but unpaid interest on this Note to be immediately due and payable in the manner and with the effect provided in the Indenture.  The Indenture provides that such declaration and its consequences may, in certain events, be annulled by the Holders of a majority in principal amount of the Outstanding Notes.  If an Event of Default with respect to the Notes relating to certain events of bankruptcy, insolvency or reorganization shall occur and be continuing, then the principal amount of and all accrued but unpaid interest on this Note shall automatically, and without any declaration or any other action on the part of the Trustee or any Holder, become due and payable as provided in the Indenture.

6.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 Notes under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in aggregate principal amount of Notes at the time Outstanding.  The

Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of Notes at the time Outstanding, on behalf of the Holders of all Notes, 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 therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

7.No reference herein to the Indenture and no provisions 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, premium, if any, and interest on this Note at the times, places and rate, and in the coin or currency, herein prescribed.

8.As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note may be registered on the Register of the Company, upon surrender of this Note for registration of transfer at the office or agency to be maintained by the Company for that purpose, or at such other office or agency as may be established by the Company for such purpose pursuant to the Indenture (initially the principal corporate trust office of the Trustee in Minneapolis, Minnesota), duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company, and duly executed by the Holder hereof or such Holder’s attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for like aggregate principal amount, will be issued to the designated transferee or transferees.

9.The Notes are issuable only in fully registered form, without coupons, in denominations of $2,000 or any amount in excess thereof that is an integral multiple of $1,000.  As provided in the Indenture, and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes in authorized denominations, as requested by the Holder surrendering the same.

10.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.

11.Prior to the due presentment of this Note for registration of transfer or exchange, the Company, the Trustee and any agent of the Company 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 Trustee, nor any such agent shall be affected by notice to the contrary.

12.Interest on this Note shall be computed on the basis of a 360-day year of twelve 30-day months.  Interest shall be payable to and excluding any Interest Payment Date.

13.The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not the Trustee.

14.This Note shall not be valid until authenticated by the manual signature of the Trustee or an Authenticating Agent.

16.Each Holder of this Note covenants and agrees by such Holder’s acceptance thereof to comply with and be bound by the foregoing provisions.

17.All terms used in this Note which are defined in the Indenture and not otherwise defined in this Note shall have the meanings assigned to them in the Indenture.
