a reference to a Section or Article is to a Section or Article of this Supplemental Indenture;

“Below Investment Grade Rating Event” means the Notes of a series become rated below Investment Grade by any two of the Rating Agencies on any date from the date of the public notice of an arrangement that results in a Change of Control until the end of the 60-day period following public notice of the occurrence of such Change of Control (which period shall be extended so long as any of such Rating Agencies has publicly announced that it is considering a possible ratings downgrade); provided, that, a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect to a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Repurchase Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Company and the Trustee in writing at the Company’s or the Trustee’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, such Change of Control (whether or not such Change of Control shall have occurred at the time of the Below Investment Grade Rating Event). The Trustee shall not be responsible for monitoring the rating status of the Notes, making any request upon any Rating Agency, or determining whether any Below Investment Grade Rating Event has occurred.

Notwithstanding the foregoing, a transaction or series of related transactions will not be deemed to involve a “Change of Control” if (i) as a result of such transaction or series of related transactions the Company becomes a direct or indirect wholly-owned Subsidiary of a holding company or a holding company becomes the successor to the Company as contemplated by the provisions under Article Eight of the Indenture and (ii) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction or series of related transactions are the same or substantially the same as the holders of the Company’s Voting Stock immediately prior to that transaction or series of related transactions.

“Fitch” means Fitch, Inc. and its successors.

“Global Notes” shall have the meaning set forth in Section 2.05.

“Initial Notes” means (i) all Notes issued on August 16, 2024 and (ii) any Notes issued in replacement for such Notes.

“Investment Grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories), a rating of BBB- or better by S&P (or its equivalent under any successor rating categories), a rating of BBB- or better by Fitch (or its equivalent under any successor rating categories) and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by the Company.

“▇▇▇▇▇’▇” means ▇▇▇▇▇’▇ Investors Service Inc., a subsidiary of ▇▇▇▇▇’▇ Corporation, and its successors.

“Net Rental Payments” under any lease for any period means the sum of the rental and other payments required to be paid in such period by the lessee thereunder, not including, however, any amounts required to be paid by such lessee (whether or not designated as rental or additional rental) on account of maintenance and repairs, insurance, taxes, assessments or similar charges.

“Notes” shall have the meaning set forth in the recitals above and shall include the Global Notes.

“Par Call Date” means, in the case of the 2029 Notes, July 15, 2029, and, in the case of the 2034 Notes, May 15, 2034.

“Principal Property” means any manufacturing plant or warehouse, together with the land upon which it is erected and fixtures comprising a part thereof, owned by the Company or one of its Subsidiaries which constitutes a “significant subsidiary” as defined in Rule 1-02 of Regulation S-X of the Exchange Act, and is located in the United States, the gross book value (without deduction of any reserve for depreciation) of which on the date as of which the determination is being made is an amount which exceeds 1% of Consolidated Net Tangible Assets, other than any such manufacturing plant or warehouse or any portion thereof (together with the land upon which it is erected and fixtures comprising a part thereof) (i) which is financed by industrial development bonds or (ii) which, in the opinion of the Company’s board of directors, is not of material importance to the Company’s and its Subsidiaries’ total business conducted, taken as a whole.

“Rating Agency” means: (i) each of ▇▇▇▇▇’▇, S&P and Fitch; and (ii) if any of ▇▇▇▇▇’▇, S&P or Fitch ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of the Company’s control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act, selected by the Company as a replacement agency for ▇▇▇▇▇’▇, S&P or Fitch, as the case may be.

“S&P” means S&P Global Ratings, a division of S&P Global Inc. and its successors.

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Company in accordance with the following two paragraphs.

The Treasury Rate will be determined by the Company or its designee (which will not be the Trustee) 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)—▇.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Company or its designee will 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 applicable 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 will interpolate to the applicable 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 will 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 is no longer published, the Company or its designee will 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 applicable Par Call Date. If there is no United States Treasury security maturing on the applicable Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the applicable Par Call Date, one with a maturity date preceding the applicable Par Call Date and one with a maturity date following the applicable Par Call Date, the Company or its designee will select the United States Treasury security with a maturity date preceding the applicable Par Call Date. If there are two or more United States Treasury securities maturing on the applicable Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, then the Company or its designee will 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 will 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.

“Trust Indenture Act” means the Trust Indenture Act of 1939, as amended.

“Voting Stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) 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.

ARTICLE 2

The Notes

Section 2.01.         Designation.

The Company hereby establishes two series of Securities, one series designated the “4.950% Senior Notes due 2029” and another series designated the “5.400% Senior Notes due 2034” for issuance under the Indenture.

Section 2.02.         Principal Amount; Series Treatment.

The 2029 Notes shall be initially limited to an aggregate principal amount of $500,000,000 and the 2034 Notes shall be initially limited to an aggregate principal amount of $500,000,000. However, the Company may, from time to time, without giving notice to or seeking the consent of the Holders of the Outstanding Notes of either series, issue additional Securities of any series, so that such additional Securities and the Outstanding Notes of such series shall be consolidated together and form a single series of Securities under the Indenture, as supplemented by this Supplemental Indenture; provided that if the additional Securities are not fungible with such Outstanding Notes of such series for United States federal income tax purposes, the additional Securities will have a separate CUSIP number. No such additional Securities of a series of Notes may be issued if an Event of Default has occurred and is continuing with respect to the applicable series of Notes.

Any additional Securities issued under this Section 2.02 shall have the same terms in all respects as the corresponding series of Securities, except that interest will accrue on the additional Securities from the most recent date to which interest has been paid on the Outstanding Notes of such series (other than the additional Securities) or, if no interest has been paid on the Outstanding Notes of such series from the first date that the Outstanding Notes of such series were originally issued under the Indenture, as supplemented by this Supplemental Indenture.

For all purposes of the Indenture and this Supplemental Indenture, all Notes of the same series, whether Initial Notes or additional Securities issued under Section 2.02, shall constitute one series of Securities and shall vote together as one series of Securities.

Section 2.03.         Maturity.

Unless previously redeemed or repurchased in full in accordance with Article 3 of this Supplemental Indenture, the 2029 Notes will become due and payable on August 15, 2029, and the 2034 Notes will become due and payable on August 15, 2034.

Section 2.04.         Interest.

The 2029 Notes will bear interest at the rate of 4.950% per annum, and the 2034 Notes will bear interest at the rate of 5.400% per annum, in each case from, and including, August 16, 2024 until their maturity or earlier redemption or repurchase, such interest to be payable semi-annually in arrears on February 15 and August 15 of each year, to the Holders of record of the Notes of such series as of the close of business on the January 31 and July 31, whether or not a Business Day, immediately preceding such interest payment dates, commencing, in the case of the Notes issued prior to such date, on February 15, 2025.

Section 2.05.         Form of Notes.

The Notes shall contain the terms set forth in, and shall be substantially in the forms of, Exhibit A and Exhibit B hereto. The terms and provisions contained in the forms of Notes set forth in Exhibit A and Exhibit B shall constitute, and are hereby expressly made, a part of the Indenture, as supplemented by this Supplemental Indenture.

Any of the Notes may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as the officers executing the same may approve (execution thereof to be conclusive evidence of such approval) and as are not inconsistent with the provisions of the Indenture, as supplemented by this Supplemental Indenture, or as may be required by the Depositary or as may be required to comply with any applicable 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 such Notes may be listed, or to conform to usage, or to indicate any special limitations or restrictions to which any particular Notes are subject.

Notwithstanding Section 303 of the Indenture, the Notes do not require a corporate seal to be reproduced thereon.

So long as the Notes of a series are eligible for book-entry settlement with the Depositary, or unless otherwise required by law, or otherwise contemplated herein, all of the Notes of such series shall be represented by one or more Notes of such series in global form registered in the name of the Depositary or the nominee of the Depositary.

Each series of Notes shall be issued in the form of one or more global securities in fully registered form (the “Global Notes”) substantially in the forms set forth in Exhibit A and Exhibit B, in each case without interest coupons, which shall be deposited on behalf of the purchasers of the Notes represented thereby with, or on behalf of, the Depositary and registered in the name of the nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as provided in this Supplemental Indenture.

The transfer and exchange of beneficial interests in any such Global Notes shall be effected through the Depositary in accordance with the Indenture and the applicable procedures of the Depositary. Except as provided in the Indenture, beneficial owners of a Global Note shall not be entitled to have certificates registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and will not be considered Holders of such Global Note.

Any Global Note shall represent such of the Outstanding Notes of the corresponding series as shall be specified therein and shall provide that it shall represent the aggregate amount of Outstanding Notes of such series from time to time endorsed thereon and that the aggregate amount of Outstanding Notes of such series represented thereby may from time to time be adjusted to reflect redemptions. Any endorsement of a Global Note to reflect any such adjustment in the amount of Outstanding Notes of such series represented thereby shall be made by the Trustee in such manner and upon instructions given by the Holder of such Notes in accordance with the Indenture and this Supplemental Indenture. Payment of principal of and premium, if any, and interest on any Global Note shall be made to the Holder thereof.

The Company and the Trustee may treat the Depositary (or its nominee) as the sole and exclusive owner and Holder of the Notes registered in its name for the purposes of payment of the principal of and premium, if any, and interest on such Notes, giving any notice permitted or required to be given to Holders under the Indenture, registering the transfer of such Notes, obtaining any consent or other action to be taken by Holders and for all other purposes whatsoever, and neither the Company nor the Trustee shall be affected by any notice to the contrary. Neither the Company nor the Trustee shall have any responsibility or obligation to any participant in the Depositary, any Person claiming a beneficial ownership interest in the Notes under or through the Depositary or any such participant, or any other Person which is not shown on the Security Register as being a Holder of Notes, the accuracy of any records maintained by the Depositary or any such participant, the payment by the Depositary or any such participant of any amount in respect of the principal of or premium, if any, or interest on the Notes, any notice which is permitted or required to be given to Holders under the Indenture, any consent given or other action taken by the Depositary as Holder, or any selection by the Depositary of any participant or other Person to receive payment of principal of or premium, if any, or interest on the Notes.

ARTICLE 3

Redemption and Repurchase Of The Notes

Section 3.01.         Optional Redemption by Company.

At any time prior to the applicable Par Call Date, each series of Notes will be redeemable, in whole or in part at any time and from time to time, 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:

(1)(a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed discounted to the redemption date (assuming that such Notes matured on the applicable Par Call Date) on a semi-annual basis (assuming a 360-day year of twelve 30-day months), at the Treasury Rate plus 20 basis points, in the case of the 2029 Notes, or plus 25 basis points, in the case of the 2034 Notes, less (b) interest accrued on such Notes to the redemption date, and

(2) 100% of the aggregate principal amount of the Notes being redeemed on the redemption date,

plus, in either case, accrued and unpaid interest on the Notes being redeemed to the redemption date.

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

Notwithstanding the foregoing, installments of interest on such Notes that are due and payable on Interest Payment Dates falling on or prior to a redemption date will be payable on such Interest Payment Dates to the registered holders as of the close of business on the relevant record date according to such Notes and the Indenture.

The Company’s actions and determinations in determining the redemption price will be conclusive and binding for all purposes, absent manifest error. For the avoidance of doubt, the Trustee shall not have any responsibility or obligation whatsoever to determine or calculate any redemption price (including, without limitation, in connection with any optional redemption). If the Company has given notice of redemption as provided in the Indenture, and has made funds available on the redemption date referred to in the notice of redemption, subject to any conditions precedent as contemplated below, the Notes called for redemption will cease to bear interest on the redemption date and the Holders of those Notes from and after the redemption date will be entitled to receive only the payment of the redemption price upon surrender of such Notes in accordance with the notice.

Notice of any option redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 10 days but not more than 60 days before the applicable redemption date to Holders of Notes being redeemed. Notice of any redemption of Notes may, at the Company’s discretion, be given subject to one or more conditions precedent, including, but not limited to, completion of a corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence of indebtedness, or an acquisition or other strategic transaction involving a change of control in us or another entity). If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied or otherwise waived on or prior to the Business Day immediately preceding the relevant redemption date. The Company will notify Holders of any such rescission as soon as practicable after the Company determines that such conditions precedent will not be able to be satisfied or the Company is not able or willing to waive such conditions precedent. Once notice of redemption is mailed or sent, subject to the satisfaction of any conditions precedent provided in the notice of redemption, the Notes called for redemption will become due and payable on the redemption date and at the applicable redemption price as set forth in this Section 3.01.

If the Company chooses to redeem less than all of a series of Notes, the Company will notify the Trustee in writing at least 25 days prior to giving notice of redemption, or a shorter period as may be satisfactory to the Trustee, of the aggregate principal amount of such Notes to be redeemed and their redemption date, and selection of such Notes for redemption will be made pro rata, by lot, or by such other method as the Trustee, in accordance with its customary procedures, deems appropriate and fair. For so long as a series of Notes is held by the Depositary (or another depositary), the redemption of such series of Notes shall be done in accordance with the policies and procedures of the applicable depositary. The Trustee will select, in accordance with its customary procedures, the Notes to be redeemed in part, which, in the case of Notes in book-entry form, will be in accordance with the procedures of any applicable depositary.

In addition, the Company may at any time acquire the Notes by means other than a redemption, whether pursuant to an issuer tender offer, open market purchase, negotiated transactions, or otherwise, so long as the acquisition does not otherwise violate the terms of the Indenture.

Section 3.02.         Change of Control Repurchase Event.

If a Change of Control Repurchase Event occurs with respect to the Notes of a series, unless the Company has exercised its right to redeem the Notes of such series as described in Section 3.01, the Company will make an offer to each Holder of Notes of such series to repurchase all or any part (in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof) of that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Notes to be repurchased plus unpaid interest, if any, accrued thereon to, but excluding, the date of repurchase. Within 30 days following any Change of Control Repurchase Event or, at the Company’s option, prior to any Change of Control, but after the public announcement of the transaction or transactions that constitute or may constitute a Change of Control, the Company will deliver or mail (or in the case of Global Notes, transmit in accordance with the procedures of the clearing agencies) a notice to each Holder, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering to repurchase the Notes of the applicable series on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is transmitted (or, in the case of a notice provided prior to the consummation of Change of Control, no later than 60 days from the date of the related Change of Control Repurchase Event), other than as may be required by law, pursuant to procedures required by such series of Notes and described in such notice. The notice shall, if transmitted prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Repurchase Event occurring on or prior to the payment date specified in the notice.

The Company will 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 Repurchase Event. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control Repurchase Event provisions of this Supplemental Indenture, 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 Repurchase Event provisions of this Supplemental Indenture by virtue of such conflict.

On the Change of Control Repurchase Event payment date for the Notes of the applicable series, the Company will, to the extent lawful:

accept for payment all Notes of such series or portions of Notes of such series properly tendered pursuant to the Company’s offer;

deposit with the Trustee an amount equal to the aggregate purchase price in respect of all Notes of such series or portions of Notes of such series properly tendered to the Company’s offer; and

deliver or cause to be delivered to the Trustee the Notes of such series properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes of such series being purchased by the Company.

The Trustee will promptly transmit to each Holder of Notes of the applicable series properly tendered the purchase price for such Notes, and the Trustee will promptly authenticate and deliver or mail (or cause to be transferred by book-entry) to each such Holder a new Note of such series equal in principal amount to any unpurchased portion of such Notes surrendered; provided that each new Note will be in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof.

The Company will not be required to make an offer to repurchase a series of Notes upon a Change of Control Repurchase Event if (i) 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 such third party purchases all Notes of the applicable series properly tendered and not withdrawn under its offer or (ii) notice of redemption of all Outstanding Notes of such series has been given pursuant to the Indenture unless and until there is a default in the payment of the applicable redemption price. In the event that such third party terminates or defaults on its offer or the Company rescinds its notice of redemption, the Company will be required to make a Change of Control offer treating the date of such termination or default as though it were the date of the Change of Control Repurchase Event. In addition, the Company will not purchase any Notes of a series if there has occurred and is continuing on the Change of Control payment date an Event of Default under the Indenture with respect to such series of Notes, other than a default in the payment of the Change of Control payment.

In the event that Holders of not less than 90% of the principal amount of the Outstanding Notes of such series validly tender and do not withdraw such Notes in a Change of Control offer and the Company purchases, or any third party making a Change of Control offer as described above, all of the Notes of such series validly tendered and not withdrawn by such Holders, the Company will have the right, on not less than 15 nor more than 60 days’ prior notice, given not more than 30 days following the purchase pursuant to the Change of Control offer, to redeem all of the Notes of such series that remain outstanding following such purchase at the purchase price specified in the Change of Control offer plus, to the extent not included in the purchase price specified in the Change of Control offer, accrued and unpaid interest thereon, to, but excluding, the redemption date (subject to the right of Holders of record on the relevant Regular Record Date to receive interest on the relevant Interest Payment Date falling on or prior to the redemption date).

Section 6.01.         Limitation on Liens.

The Company will not, and will not permit any Subsidiary of the Company to, issue, assume or guarantee any Debt if such Debt is secured by a mortgage, pledge, security interest or lien (a “mortgage” or “mortgages”) upon any of the Principal Property of the Company or any Subsidiary of the Company or upon any shares of stock or other equity interest or Debt of any Subsidiary of the Company (whether such property, shares of stock or other equity interest or Debt is now owned or hereafter acquired) which owns any Principal Property, without in any such case effectively providing that the Notes shall be secured equally and ratably with (or prior to) such Debt until such time as such Debt is no longer secured by such mortgages; provided, however, that the foregoing restrictions shall not apply to:

(a)            Mortgages existing on the date the Notes are originally issued or mortgages provided for under the terms of agreements existing on such date;

(b)            Mortgages on Current Assets securing Current Liabilities;

(c)            Mortgages on any property acquired, constructed, altered or improved by the Company or any Subsidiary of the Company after the date of the Indenture that are created or assumed contemporaneously with or within one year after such acquisition (or in the case of property constructed, altered or improved, after the completion and commencement of commercial operation of such property, whichever is later) to secure or provide for the payment of the purchase price or cost thereof, provided that in the case of any such construction, alteration or improvement the mortgages shall not apply to any property theretofore owned by the Company or any Subsidiary of the Company other than (i) the property so altered or improved and (ii) any theretofore unimproved real property on which the property so constructed or altered, or the improvement, is located;

(d)            Existing mortgages on property the Company or any of its Subsidiaries acquire (including mortgages on any property acquired from a Person that is consolidated with or merged with or into the Company or a Subsidiary of the Company) or mortgages outstanding at the time any Person becomes a Subsidiary of the Company that are not incurred in connection with such entity becoming a Subsidiary of the Company;

(e)            Mortgages in favor of the Company or any Subsidiary of the Company;

(f)            Mortgages on any property (i) in favor of domestic or foreign governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or statute, (ii) securing indebtedness incurred to finance all or any part of the purchase price or cost of constructing, installing or improving the property subject to such mortgages including mortgages to secure Debt of the pollution control or industrial revenue bond type, or (iii) securing indebtedness issued or guaranteed by the United States, any State, any foreign country or any department, agency, instrumentality or political subdivision of any such jurisdiction;

(g)            Mortgages securing the Notes;

(h)            Any interest of title of a lessor or secured by a lessor’s interest under any lease permitted under the Indenture;

(i)             Mortgages on the identifiable proceeds of any property or asset subject to a mortgage otherwise permitted under the Indenture; and

(j)             Any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any mortgage referred to in the foregoing clauses; provided, however, that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, together with the reasonable costs related to such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property that secured the mortgage so extended, renewed or replaced (plus improvements on such property).

Notwithstanding the foregoing, the Company and any Subsidiary of the Company may, without securing the Notes, issue, assume or guarantee secured Debt (that would otherwise be subject to the foregoing restrictions) in an aggregate amount that, together with all other such secured Debt and the aggregate amount of Attributable Indebtedness of the Company and its Subsidiaries deemed to be outstanding in respect of all Sale/Leaseback Transactions entered into pursuant to Section 1010 of the Indenture and/or Section 6.02 hereof (excluding any such Sale/Leaseback Transactions the proceeds of which have been applied in accordance with clauses (2) or (3) of Section 1010 of the Indenture and/or clauses (b) or (c) of Section 6.02 hereof), does not exceed 10% of the Consolidated Net Worth, as shown on a consolidated balance sheet as of a date not more than 90 days prior to the proposed transaction prepared by the Company in accordance with GAAP.

Section 6.02.         Limitation on Sale and Leaseback Transactions.

The Company will not, and will not permit any of its Subsidiaries to, enter into any Sale/Leaseback Transaction involving any Principal Property with any Person (other than the Company or a Subsidiary of the Company) unless:

(a)            At the time of entering into such Sale/Leaseback Transaction, the Company or such Subsidiary would be entitled to incur Debt, in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction, secured by a mortgage on the Principal Property subject to such Sale/Leaseback Transaction, pursuant to Section 1009 of the Indenture and Section 6.01 hereof without equally and ratably securing the Notes pursuant to such provisions;

(b)            After the date on which the Notes are first issued and within a period commencing six months prior to the consummation of such Sale/Leaseback Transaction and ending six months after the consummation thereof, the Company or such Subsidiary shall have expended for property used or to be used in the ordinary course of business of the Company or such Subsidiary (including amounts expended for additions, expansions, alterations, repairs and improvements thereto) an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction, and the Company shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (c) below); or

(c)            During the 12-month period after the effective date of such Sale/Leaseback Transaction, the Company shall have applied to the voluntary defeasance or retirement of Securities or any pari passu indebtedness of the Company an amount equal to the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction, which amount shall not be less than the fair value of such property at the time of entering into such Sale/Leaseback Transaction (adjusted to reflect any amount expended by the Company as set forth in clause (b) above), less an amount equal to the principal amount of Notes and pari passu indebtedness voluntarily defeased or retired by the Company within such 12-month period and not designated as a credit against any other Sale/Leaseback Transaction entered into by the Company or any Subsidiary of the Company during such period.

UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE DEPOSITORY TRUST COMPANY, A NEW YORK CORPORATION (“DTC”), TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR PAYMENT, AND SUCH CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF CEDE & CO., OR SUCH OTHER NAME AS REQUESTED BY AN AUTHORIZED REPRESENTATIVE OF DTC, ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL, SINCE THE REGISTERED OWNER HEREOF, CEDE & CO., HAS AN INTEREST HEREIN.

UNLESS AND UNTIL THIS CERTIFICATE IS EXCHANGED IN WHOLE OR IN PART FOR NOTES IN CERTIFICATED FORM, THIS CERTIFICATE MAY NOT BE TRANSFERRED EXCEPT AS A WHOLE BY THE DEPOSITARY TO A NOMINEE THEREOF OR BY A NOMINEE THEREOF TO THE DEPOSITARY OR ANOTHER NOMINEE OF THE DEPOSITARY OR BY THE DEPOSITARY OR ANY SUCH NOMINEE TO A SUCCESSOR OF THE DEPOSITARY OR A NOMINEE OF SUCH SUCCESSOR.

BORGWARNER INC., a Delaware corporation (herein referred to as the “Company,” which term includes any successor under the Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal sum of $500,000,000 on August 15, 2029 (the “Maturity Date”), unless redeemed or repurchased prior to such date as permitted or required by this Note, and to pay interest on the outstanding principal amount of this Note semi-annually in arrears on February 15 and August 15 of each year (each, an “Interest Payment Date”), commencing February 15, 2025, at 4.950% per annum until the principal hereof is paid or duly provided for. Interest will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Any payment of principal, premium, if any, or interest, required to be made on a day that is not a Business Day (as defined below) need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on such day and no interest shall accrue as a result of such delayed payment. Interest payable on each Interest Payment Date will include interest accrued from and including, August 16, 2024 or from, and including, the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, to, but excluding the applicable Interest Payment Date.

Any such interest not so punctually paid or duly provided for (“Defaulted Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee (referred to herein), notice whereof shall be given to the Holder of this Note not less than ten days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture.

For purposes of this Note, “Business Day” means any day that is not a Saturday or Sunday or legal holiday in New York, New York, and on which commercial banks are open for business in New York, New York.

So long as this Note remains in book-entry form, all payments of principal and premium, if any, and interest will be made by the Company in immediately available funds.

General. This Note is one of a duly authorized issue of securities (herein called the “Securities”) of the Company, issued and to be issued in one or more series under an Indenture, dated as of September 23, 1999, between the Company and The Bank of New York Mellon Trust Company, N.A., successor in interest to ▇.▇. ▇▇▇▇▇▇ Trust Company, N.A.

This Note is one of a duly authorized series of Securities designated as “4.950% Senior Notes due 2029” (collectively, the “Notes”).

Exhibit A-2

Optional Redemption. The Company may, at its option, redeem some or all of the Notes, in whole or in part at any time and from time to time, as described in Section 3.01 of the Ninth Supplemental Indenture. In addition, the Company may at any time acquire the Notes by means other than a redemption, whether pursuant to an issuer tender offer, open market purchase, negotiated transactions, or otherwise, so long as the acquisition does not otherwise violate the terms of the Indenture.

Change of Control Repurchase Event. This Note shall be repurchased by the Company upon the occurrence of a Change of Control Repurchase Event on the terms and conditions set forth in the Indenture.

Events of Default. If an Event of Default with respect to the Notes shall have occurred 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.

Modification and Waivers; Obligations of the Company Absolute. 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. Such amendment may be effected 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 aggregate principal amount of all Securities issued under the Indenture at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of not less than a majority in aggregate principal amount of all Outstanding Securities affected by certain provisions of the Indenture, on behalf of the Holders of all such Outstanding Securities, to waive compliance by the Company with such provisions. Furthermore, provisions in the Indenture permit the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of an individual series to waive on behalf of all of the Holders of Securities of such individual series certain past defaults under the Indenture and their consequences. Any such consent or waiver applicable to the Notes shall be conclusive and binding upon the Holder of this Note and upon all future Holders of this Note and of any Note 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 Note.

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 premium, if any, and interest on this Note at the times, place and rate, and in the coin or currency herein prescribed.

The Indenture contains provisions for defeasance at any time of (a) the entire indebtedness of the Company on this Note and (b) certain restrictive covenants and the related defaults and Events of Default, upon compliance by the Company with certain conditions set forth therein, which provisions apply to this Note.

Exhibit A-3

Registration of Transfer or Exchange. As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registrable in the Security Register upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and premium, if any, and interest on this Note are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations herein and therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same.

This Note is a Global Security. If the Depositary (as defined in the Ninth Supplemental Indenture) is at any time unwilling, unable or ineligible to continue as Depositary and a successor Depositary is not appointed by the Company within 90 days or an Event of Default under the Indenture applicable to the Notes has occurred and is continuing, the Company will issue Notes in certificated form in exchange for each Global Note. In addition, the Company may at any time determine not to have Notes represented by a Global Note and, in such event, will issue Notes in certificated form in exchange in whole for the Global Note representing such Note. In any such instance, an owner of a beneficial interest in a Global Note will be entitled to physical delivery in certificated form of Notes equal in principal amount to such beneficial interest and to have such Notes registered in its name. Notes so issued in certificated form will be issued in denominations of $2,000 or any amount in excess thereof which is an integral multiple of $1,000 and will be issued in registered form only, without coupons.

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 Trustee and any agent of the Company or the Trustee may treat the Holder 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.

Defined Terms. All terms used in this Note (except as herein otherwise expressly provided or unless the context otherwise requires) which are defined in the Indenture and are not otherwise defined herein shall have the meanings assigned to them in the Indenture.

Governing Law. This Note shall be governed by and construed in accordance with the laws of the State of New York.

Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.
