Indenture. However, the Company may, from time to time, without the consent of the Holders of the outstanding Notes, issue additional Notes, so that such additional Notes and the other Outstanding Notes of this series shall be consolidated together and form a single series of Securities under the Indenture, as supplemented by this Supplemental Indenture.

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

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

Unless previously redeemed or repurchased in full in accordance with Article 3 of this Supplemental Indenture, the Notes will become due and payable on May 19, 2031.

Date” with respect to the Notes). Interest on the Notes shall be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Notes (or from May 19, 2021, if no interest has been paid on the Notes) to but excluding the next scheduled Interest Payment Date.

If any Interest Payment Date, maturity date or earlier date of redemption or repurchase falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date the payment was due and no interest shall accrue on the amount so payable for the period from and after that Interest Payment Date, that maturity date or that date of redemption or repurchase, as the case may be.

The principal of each Note payable at maturity or upon earlier redemption shall be paid against presentation and surrender of such Note at the office or agency maintained for such purpose in London, initially the Corporate Trust Office of the Paying Agent, in euro.

Except as provided for in Section 2.07, owners of beneficial interests in the Global Securities will not be entitled to have Notes registered in their names, and will not receive or be entitled to receive physical delivery of Notes in definitive form. So long as the Common Depositary or its nominee is the registered Holder of the Global Securities, the Common Depositary or its nominee, as the case may be, shall be considered the sole owner or Holder of the Notes represented by such Global Securities for all purposes under the Indenture and the Notes.

(b) The terms and provisions contained in the form of Notes set forth in Exhibit A shall constitute, and are hereby expressly made, a part of the Indenture, as supplemented by this Supplemental Indenture.

Notwithstanding the foregoing, in considering the interests of Holders while the Notes are represented by the Global Securities held on behalf of Clearstream and Euroclear, the Trustee may have regard to any information provided to it by or on behalf of Clearstream and Euroclear as to the identity (either individually or by category) of their respective direct participants and may consider such interests as if these direct participants were Holders of the Global Securities, provided that, in doing so, the Trustee shall not have any responsibility or liability for any records relating to, or payments made on account of, beneficial ownership interests in the Global Securities or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

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

(c) Denominations and Payments. The Notes shall be issued only in minimum denominations of €100,000 and integral multiples of €1,000 in excess thereof. All payments of principal, premium or Redemption Price, if any, and interest in respect of the Notes shall be made by the Company in immediately available funds.

(a) The Global Securities shall be exchanged by the Company for Definitive Securities if:

(i) Euroclear or Clearstream notify the Company that it is no longer willing or able to act as clearing agency for the Notes;

(ii) the Company, at its option, notifies the Trustee in writing that it elects to cause the issuance of certificated notes; or

(iii) there has occurred and is continuing an Event of Default with respect to the Notes.

(b) Whenever a Global Security is exchanged for one or more Definitive Securities, it shall be surrendered by the Holder thereof to the Security Registrar and Transfer Agent and cancelled by the Security Registrar and Transfer Agent. All Definitive Securities issued in exchange for a Global Security, a beneficial interest therein or a portion thereof shall be registered in the names, and issued in any approved denominations, requested by or on behalf of the Common Depositary (in accordance with its customary procedures).

(c) Any owner of a beneficial interest in a Global Security shall, by acceptance of such beneficial interest in the Global Security, agree that transfer of beneficial interests in such Global Security may be effected only through a book-entry system maintained by such Holder (or its agent), and that, subject to Section 2.07(a), ownership of a beneficial interest in the Notes represented thereby shall be required to be reflected in book-entry form. Transfers of a Global Security shall be limited to transfer in whole and not in part, to the Common Depositary, its successors and their respective nominees. Interests of beneficial owners in a Global Security shall be transferred in accordance with the rules and procedures of Euroclear and Clearstream (or their respective successors).

Section 3.01. Optional Redemption by Company. The Notes may be redeemed at the option of the Company on the terms and conditions set forth in the form of Note set forth as Exhibit A.

Section 3.02. Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs, unless the Company has exercised its right to redeem the Notes as described in Section 3.01, the Company shall make an offer to each Holder to repurchase all or any part (in minimum denominations of €100,000 and any 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.

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 shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control Repurchase Event.

The Paying Agent shall promptly transmit its check or otherwise cause to be paid to each Holder of Notes properly tendered the purchase price for such Notes, and the Trustee shall promptly authenticate and deliver (or cause to be transferred by book-entry) to each such Holder a new Note 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 €100,000 or an integral multiple of €1,000 in excess thereof.

The Company shall not be required to make an offer to repurchase the 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 properly tendered and not withdrawn under its offer or (ii) notice of redemption of all outstanding Notes 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 shall not purchase any Notes if there has occurred and is continuing on the Change of Control payment date an Event of Default under the Indenture, other than a default in the payment of the Change of Control payment.

Section 3.03. Redemption for Tax Reasons. If as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any taxing authority thereof or therein), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after May 12, 2021, the Company becomes or, based upon a written opinion of independent counsel of recognized standing selected by the Company, will become obligated to pay Additional Amounts with respect to the Notes as set forth in Article 4 hereof, then the Notes may be redeemed at the option

BORGWARNER INC.

€1,000,000,000

1.000% Senior Note due 2031

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 BT Globenet Nominees Limited, or registered assigns, the principal sum of €1,000,000,000 on May 19, 2031 (the “Maturity Date”), unless redeemed or repurchased prior to such date as permitted or required by this Note. Interest shall be paid at the rate of 1.000% per annum from May 19, 2021 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, on May 19 of each year, commencing on May 19, 2022 (each an “Interest Payment Date”), until the principal hereof is paid or made available for payment. Interest on this Note shall be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on this Note (or from May 19, 2021, if no interest has been paid on this Note) to but excluding the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) (as defined in the rulebook of the International Capital Market Association) day count convention. If any Interest Payment Date, maturity date or earlier date of redemption or repurchase falls on a day that is not a Business Day, the required payment shall be made on the next Business Day as if it were made on the date the payment was due and no interest shall accrue on the amount so payable for the period from and after that Interest Payment Date, that maturity date or that date of redemption or repurchase, as the case may be

General. This Note is one of a duly authorized issue of securities (the “Securities”) of the Company, issued and to be issued in one or more series under an Indenture, dated as of September 23, 1999 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. successor in interest to J.P. Morgan Trust Company, N.A. (successor in interest to The Chase Manhattan Trust Company, National Association), a national banking association, as trustee (the “Original Trustee”), as supplemented by the Eighth Supplemental Indenture, dated as of May 19, 2021 (the “Eighth Supplemental Indenture”), between the Company and Deutsche Bank Trust Company Americas, as series trustee (the “Trustee,” which term includes any successor trustee under the Indenture with respect to a series of which this Note is a part), paying agent, transfer agent and security registrar (the “Paying Agent”, the “Transfer Agent” and/or the “Security Registrar”), and as it may be supplemented from time to time (herein called, collectively, the “Indenture”), to which indenture and all indentures supplemental thereto, reference is hereby made, to the extent applicable, 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 Note is one of a duly authorized series of Securities designated as “1.000% Senior Notes due 2031” (collectively, the “Notes”).

Exhibit A-1

Optional Redemption. The Company may redeem the Notes at its option at any time, in whole or from time to time in part, prior to February 19, 2031 (the “Par Call Date”) at a Redemption Price (the “Optional Redemption Price”) equal to the sum of:

(i) 100% of the principal amount of the Notes being redeemed, plus unpaid interest, if any, accrued thereon to, but excluding, the redemption date; and

(ii) the Make-Whole Amount (as defined below), if any, with respect to the Notes.

In addition, on or after the Par Call Date, the Company may redeem the Notes at its option, in whole or from time to time in part, at the Optional Redemption Price excluding any Make-Whole Amount.

“Make-Whole Amount” means, in connection with any optional redemption of the Notes, the excess, if any, of:

“Reinvestment Rate” means the Comparable Government Bond Rate (as defined below) plus 0.20%.

“Comparable Government Bond Rate” means the rate equal to the gross redemption yield (rounded to three decimal places, 0.0005 being rounded upwards) of the Comparable Government Bond (as defined below) on the third Business Day prior to the date fixed for redemption, calculated on the basis of the middle market price of the Comparable Government Bond (as defined below) prevailing at 11:00 a.m. (London time) on such Business Day as determined by an independent investment bank selected by the Company in accordance with generally accepted market practice at such time.

“Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, at the discretion of an independent investment bank selected by the Company, a German Bundesanleihe security whose maturity is closest to the maturity of the Notes, or if such independent investment bank in its discretion considers that such similar bond

Exhibit A-2

is not in issue, such other German Bundesanleihe security as such independent investment bank may, with the advice of three brokers of, and/or market makers in, German Bundesanleihe securities selected by such independent investment bank, determine to be appropriate for determining the Comparable Government Bond Rate.

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 for the redemption, subject to any conditions precedent as contemplated below, the Notes called for redemption shall cease to bear interest on the redemption date and the Holders of those Notes from and after the redemption date shall be entitled to receive only the payment of the Optional Redemption Price upon surrender of the Notes in accordance with the notice.

The Company shall give notice of any such redemption to Holders of the Notes, at their addresses, as shown in the Security Register for the Notes, not more than 60 nor less than 10 days prior to the redemption date. The notice of redemption will specify, among other items, the Redemption Price and the principal amount of the Notes held by the Holder to be 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 the Company 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 prior to the Redemption Date or by such earlier date as may be required by the applicable securities depository, or, if earlier, 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 becomes due and payable on the redemption date and at the applicable Redemption Price provided for herein.

Unless the Company defaults in payment of the Redemption Price, on and after the redemption date, interest shall cease to accrue on this Note or portions thereof called for redemption.

If the Company chooses to redeem less than all of the Notes, it shall notify the Trustee in writing at least 45 days prior to giving notice of redemption, or a shorter period as may be satisfactory to the Trustee, of the aggregate principal amount of Notes to be redeemed and their redemption date. The Trustee shall select, in accordance with its customary procedures, the Notes to be redeemed in part, which, in the case of Notes in book-entry form, shall be in accordance with the procedures of any applicable depositary.

Exhibit A-3

Change of Control Repurchase Event. This Note shall be repurchased by the Company upon the occurrence of a Change of Control Repurchase Event (as defined in the Indenture) 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.
