TERMS AND CONDITIONS OF THE NOTES

Section 2.01. Terms of the Notes. The following terms relating to the 2054 Notes are hereby established:

(a) Designation, Maturity and Principal Amount. There is hereby authorized a series of Notes designated the “6.875% Fixed-to-Fixed Reset Rate Junior Subordinated Notes due 2054” initially offered in the aggregate principal amount of $500,000,000, which amount shall be as set forth in an Authentication Order for the authentication and delivery of such 2054 Notes pursuant to Section 2.02 of the Base Indenture.

(b) Form of the Notes.

(i) The 2054 Notes are to be substantially in the form of Exhibit A hereto. The 2054 Notes shall be numbered, lettered, or otherwise distinguished in such manner or in accordance with such plans as the Officer(s) of the Issuers executing the same may determine with the approval of the applicable agent.

(c) Note Guarantees. The 2054 Notes shall have the benefit of the Note Guarantees by the Guarantor executing this First Supplemental Indenture and future Guarantors pursuant to Section 6.02 hereof.

(d) Additional Notes.

(i) The Issuers may, without notice to or the consent of the Holders of the 2054 Notes, issue Additional 2054 Notes having identical terms and conditions as the 2054 Notes, except for the issue date, issue price and first Interest Payment Date, in an unlimited aggregate principal amount. Any such Additional 2054 Notes will be part of the same series as the 2054 Notes, and will be treated as one class with such series of 2054 Notes, including, without limitation, for purposes of voting and redemptions; provided, however, that if such Additional 2054 Notes are not fungible with the other 2054 Notes for U.S. federal income tax purposes, such Additional 2054 Notes shall not have the same “ISIN” or “CUSIP” number or other applicable identification number as the other 2054 Notes (it being understood that, as described in Section 7.02, any Additional 2054 Notes that have a different allocation than the initial allocation with respect to the outstanding 2054 Notes shall not be considered as not fungible for U.S. federal income tax purposes under this proviso solely as a result of such difference in allocation).

(e) Principal Payment. The 2054 Notes will mature on December 15, 2054.

(f) Interest Rate; Interest Payment Date; Computation of Interest.

(i) The 2054 Notes will bear interest (i) from and including the date of the original issuance to, but excluding, December 15, 2029 at an annual rate of 6.875% and (ii) from and including December 15, 2029 during each Interest Reset Period at an annual rate equal to the Five-Year Treasury Rate as of the most recent Reset Interest Determination Date, plus 3.385%. The 2054 Notes will mature on December 15, 2054. Interest will accrue from September 13, 2024 and will, subject to the Company’s right to defer interest payments (as described in Article 4), be payable semi-annually in arrears on June 15 and December 15 of each year (each, an “Interest Payment Date”), beginning on June 15, 2025. If interest payments are deferred or otherwise not paid, they will accrue and compound until paid at the same rate at which the 2054 Notes bear

-7-

interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the 2054 Notes) to the extent permitted by law. As permitted by the terms of the 2054 Notes, if interest payments are deferred or otherwise not paid up to a redemption date that does not fall on an Interest Payment Date, they will accrue and compound until paid at the same rate at which the 2054 Notes bear interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the 2054 Notes) to the extent permitted by law. The amount of interest payable for any interest accrual period will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed on the basis of the number of days in the period using 30-day calendar months. All references to “interest” on the 2054 Notes and, insofar as it relates to the 2054 Notes, this Indenture, shall be deemed to include semi-annual interest payments and applicable interest on interest payments accrued but not paid on the applicable Interest Payment Date.

(ii) Unless all of the outstanding 2054 Notes have been redeemed, the Issuers will appoint a calculation agent (the “Calculation Agent”) with respect to the 2054 Notes prior to the applicable Reset Interest Determination Date. The Issuers or any of their affiliates may assume the duties of the Calculation Agent. The applicable interest rate for each Interest Reset Period will be determined by the Calculation Agent as of the applicable Reset Interest Determination Date. If the Issuers or one of their affiliates is not the Calculation Agent, the Calculation Agent will notify the Issuers of the interest rate for the relevant Interest Reset Period promptly upon such determination. The Issuers will notify the Paying Agent of such interest rate, promptly upon making or being notified of such determination. The Calculation Agent’s determination of any interest rate and its calculation of the amount of interest for any Interest Reset Period will be conclusive and binding absent manifest error, will be made in the Calculation Agent’s sole discretion and, notwithstanding anything to the contrary in the documentation relating to the 2054 Notes, will become effective without consent from any other person or entity. Such determination of any interest rate and calculation of the amount of interest will be on file at the Issuers’ principal offices and will be made available to any Holder of the 2054 Notes upon request. In no event shall the Trustee be the Calculation Agent, nor shall it have any liability for any determination made by or on behalf of such Calculation Agent.

(iii) Interest will be paid to the person in whose name a 2054 Note is registered at the close of business on June 1 or December 1 (whether or not a Business Day), as the case may be, immediately preceding the relevant Interest Payment Date (each, a “Regular Record Date”).

(iv) If any Interest Payment Date, the Stated Maturity or a redemption date falls on a day that is not a Business Day, the required payment will be made on the next succeeding Business Day with the same force and effect as if made on such scheduled payment date, and no interest on such payment will accrue in respect of the delay.

(g) Place of Payment of Principal and Interest. Section 4.02 of the Base Indenture shall apply to the 2054 Notes.

(h) Optional Redemption. The 2054 Notes shall be redeemable as specified in Article 3 of this First Supplemental Indenture and Article 3 of the Base Indenture.

OPTION TO DEFER INTEREST PAYMENTS

Section 4.01. Option to Defer Interest Payments.

(a) So long as no Event of Default (as defined in Section 9.01) with respect to the 2054 Notes has occurred and is continuing, the Issuers may, at their option, defer interest payments on the 2054 Notes on one or more occasions, from time to time, for up to 20 consecutive semi-annual Interest Payment Periods (each such deferral period, which will commence on the Interest Payment Date on which the first such deferred interest payment otherwise would have been made, an “Optional Deferral Period”), except that no such Optional Deferral Period may extend beyond the Stated Maturity of the 2054 Notes or end on a day other than the day immediately preceding an Interest Payment Date, and the Issuers may not begin a new Optional Deferral Period, and may not pay current interest on the 2054 Notes until the Issuers have paid all accrued interest on the 2054 Notes from the previous Optional Deferral Period.

(b) If the Issuers defer interest for a period of 20 consecutive Interest Payment Periods from the commencement of an Optional Deferral Period, the Issuers will be required to pay all accrued and unpaid interest at the conclusion of the 20 consecutive Interest Payment Periods. If the Issuers fail to pay in full all accrued and unpaid interest at the conclusion of the 20 consecutive Interest Payment Periods, and such failure continues for 30 days, an Event of Default that gives rise to acceleration of principal and interest on the 2054 Notes will occur under the Indenture.

(c) During any Optional Deferral Period, interest on the 2054 Notes will continue to accrue at the then-applicable interest rate on the 2054 Notes. In addition, during any Optional Deferral Period, interest on the deferred interest (“Compound Interest”) will accrue at the then-applicable interest rate on the 2054 Notes, compounded semi-annually, to the extent permitted by applicable law. No interest will be due and payable on the 2054 Notes until the end of the Optional Deferral Period except upon a redemption of the 2054 Notes during the Optional Deferral Period. The Interest Payment Date falling immediately after the last day of an Optional Deferral Period shall not be deemed to fall on a day during such Optional Deferral Period.

-11-

(d) No interest will be due or payable on the 2054 Notes during any such Optional Deferral Period, except upon a redemption of any Notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any Compound Interest) on the 2054 Notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the 2054 Notes shall have been declared due and payable as the result of an Event of Default with respect to the 2054 Notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any Compound Interest, on the 2054 Notes shall become due and payable).

(e) All references in the 2054 Notes and, insofar as relates to the 2054 Notes, the Indenture, to “interest” on the 2054 Notes shall be deemed to include any such deferred interest and, to the extent permitted by applicable law, any Compound Interest, unless otherwise expressly stated or the context otherwise requires.

(f) Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Issuers may elect, at their option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the Stated Maturity of the 2054 Notes. The Issuers may also elect, at their option, to shorten the length of any Optional Deferral Period. No Optional Deferral Period (including as extended or shortened) may end on a day other than the day immediately preceding an Interest Payment Date. At the end of any Optional Deferral Period, if all amounts then due on the 2054 Notes, including all accrued and unpaid interest thereon (including, without limitation and to the extent permitted by applicable law, any deferred interest and any Compound Interest), are paid, the Issuers may elect to begin a new Optional Deferral Period; provided, however, that, without limitation of the foregoing, the Issuers may not begin a new Optional Deferral Period unless the Issuers have paid all accrued and unpaid interest on such Notes (including, without limitation and to the extent permitted by applicable law, any deferred interest and any Compound Interest) from any previous Optional Deferral Period.

(g) During any Optional Deferral Period, the Company (and its majority-owned subsidiaries, as applicable) will not do any of the following (subject to the exceptions set forth in the next succeeding paragraph):

(i) declare or pay any dividends or distributions on any of the Issuers’ or the Guarantor’s Share Capital;

(ii) redeem, purchase, acquire or make a liquidation payment with respect to any of the Issuers’ or the Guarantor’s Share Capital;

(iii) pay any principal, interest (to the extent such interest is deferrable) or premium on, or repay, repurchase or redeem any of the Company’s indebtedness that ranks equally with or junior to the 2054 Notes in right of payment (including debt securities of other series); or

(iv) make any payments with respect to any guarantees by the Issuers or the Guarantor of any indebtedness if such guarantees rank equally with or junior to the 2054 Notes in right of payment.

-12-

(h) However, the foregoing provisions of Section 4.01(g) shall not prevent or restrict the Issuers from making:

(i) distributions or other payments to the Company or any direct or indirect subsidiary of the Company;

(ii) purchases, redemptions or other acquisitions of the Issuers’ or the Guarantor’s Share Capital in connection with any employment contract, incentive plan, benefit plan or other similar arrangement with or for the benefit of employees, officers, directors, agents, consultants or a share purchase, dividend reinvestment or similar plan, or the satisfaction of the Issuers’ obligations pursuant to any contract or security outstanding on the date that the payment of interest is deferred requiring the Issuers to purchase, redeem or acquire the Issuers’ or the Guarantor’s Share Capital;

(iii) any payment, repayment, redemption, purchase, acquisition or declaration of a dividend as a result of any reclassification of the Issuers’ or the Guarantor’s Share Capital or the exchange or conversion of all or a portion of one class or series of the Issuers’ or the Guarantor’s Share Capital for another class or series of the Issuers’ or the Guarantor’s Share Capital;

(iv) the purchase of fractional interests in shares of the Issuers’ or the Guarantor’s Share Capital pursuant to the conversion or exchange provisions of such Share Capital or the security being converted or exchanged or in connection with the settlement of share purchase contracts;

(v) dividends, payments or distributions payable in shares of the Issuers’ or the Guarantor’s Share Capital (or rights to acquire the Issuers’ or the Guarantor’s Share Capital), or purchases, redemptions or acquisitions of the Issuers’ or the Guarantor’s Share Capital in connection with the issuance or exchange of the Issuers’ or the Guarantor’s Share Capital (or of securities convertible into or exchangeable for shares of the Issuers’ or the Guarantor’s Share Capital) and distributions in connection with the settlement of share purchase contracts outstanding on the date that the payment of interest is deferred;

(vi) redemptions, exchanges, acquisitions or repurchases of, or with respect to, any rights outstanding under any employment contract, incentive plan, benefit plan or similar arrangement of the Issuers or the Issuers’ subsidiaries or in connection with a dividend reinvestment or share purchase plan;

(vii) implementing a shareholder rights plan, or issuing rights, shares or other property under such plan, or any redemption, repurchase or acquisition of any such rights pursuant thereto;

(viii) settling conversion of any convertible notes that rank equally with the 2054 Notes; or

(ix) payments under any preferred trust securities or subordinated notes, or any guarantee thereof, executed and delivered by the Issuers or any of the Issuers’ majority-owned subsidiaries, in each case that rank equal in right of payment to the 2054 Notes with respect to which the Issuers have elected to defer the payment of interest, or the related guarantee (as the case may be), so long as the amount of payments made on account of such securities or guarantees is paid on all such securities and guarantees then outstanding on a pro rata basis in proportion to the full payment to which each series of such securities and guarantees is then entitled if paid in full.

-13-

(i) The Issuers will give DTC, the Holders of the 2054 Notes, the Trustee and the Registrar and Paying Agent written notice of the Issuers’ election of, or any shortening or extension of, an Optional Deferral Period at least 15 Business Days prior to the earlier of (1) each next succeeding Interest Payment Date or (2) the date upon which the Issuers are required to give notice to any applicable self-regulatory organization or to Holders of the 2054 Notes of the next succeeding Interest Payment Date or the Regular Record Date therefor. The record date for the payment of deferred interest and, to the extent permitted by applicable law, any Compound Interest payable on the Interest Payment Date immediately following the last day of an Optional Deferral Period will be the Regular Record Date with respect to such Interest Payment Date.

ARTICLE 5

SUBORDINATION

Section 5.01. Subordination.

(a) The 2054 Notes will be subordinated in right of payment to the prior payment in full of all the Issuers’ and the Guarantor’s Senior Indebtedness. Accordingly, upon:

(i) any payment by, or distribution of the assets of, the Issuers or the Guarantor upon its dissolution, winding-up, liquidation or reorganization, whether voluntary or involuntary or in bankruptcy, insolvency, receivership or other proceedings; or

(ii) a failure to pay any interest, principal or other monetary amounts due on any of the Issuers’ or the Guarantor’s Senior Indebtedness when due and continuance of that default beyond any applicable grace period; or

(iii) acceleration of the maturity of any of the Issuers’ or the Guarantor’s Senior Indebtedness as a result of a default;

the holders of all such Senior Indebtedness will be entitled to receive: in the case of clause (i) above, payment of all amounts due or to become due on all Senior Indebtedness; or in the case of clauses (ii) and (iii) above, payment of all amounts due on all Senior Indebtedness, before the Holders of the 2054 Notes are entitled to receive any payment. So long as any of the events in clauses (i), (ii), or (iii) above has occurred and is continuing, any amounts payable or assets distributable on the 2054 Notes will instead be paid or distributed, as the case may be, directly to the holders of Senior Indebtedness to the extent necessary to pay, in the case of clause (i) above, all amounts due or to become due upon all such Senior Indebtedness, or, in the case of clauses (ii) and (iii) above, all amounts due on all such Senior Indebtedness, and, if any such payment or distribution is received by the Trustee or the Paying Agent under the Indenture or the Holders of any of the 2054 Notes before all Senior Indebtedness due and to become due or due, as applicable, is paid, such payment or distribution must be paid over to the holders of the unpaid Senior Indebtedness. Subject to paying the Senior Indebtedness due and to become due in the case of clause (i) or the Senior Indebtedness due in the case of clauses (ii) and (iii), the Holders of the 2054 Notes will be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or distributions of assets of the Issuers or the Guarantor applicable to such Senior Indebtedness until the 2054 Notes are paid in full.

(a) Payments made by the Issuers, the Guarantor or a Paying Agent, as applicable, on the 2054 Notes or in respect of the Note Guarantee will be made free and clear of, and without withholding or deduction for or on account of, any present or future income, stamp or other tax, duty, levy, impost, assessment or other governmental charge of any nature whatsoever (“Taxes”), unless the Issuers, the Guarantor or a Paying Agent is required to withhold or deduct Taxes by law.

(b) If any withholding or deduction for or on account of Taxes imposed or levied by or on behalf of Jersey, Ireland, any other jurisdiction (other than the United States or any state thereof or the District of Columbia, or any political subdivision of any such state or the District of Columbia, or taxing authority or agency thereof or therein) in which the Issuers or the Guarantor is incorporated, organized, engaged in business or otherwise resident for tax purposes, or any other jurisdiction (other than the United States or any state thereof or the District of Columbia, or any political subdivision of any such state or the District of Columbia, or taxing authority or agency thereof or therein) from or through which such payment is made, or in each case any political subdivision or taxing authority or agency thereof or therein (each, a “Relevant Jurisdiction”) is at any time required by law to be made from any payment made with respect to the 2054 Notes or the Note Guarantee, the Issuers or the Guarantor, as applicable, will pay such additional amounts (“Additional Amounts”) on the 2054 Notes or in respect of the Note Guarantee as may be necessary so that the net amount received by each Holder of the 2054 Notes (including Additional Amounts) after such withholding or deduction will not be less than the amount the Holder would have received if such Taxes had not been withheld or deducted; provided that no Additional Amounts will be payable with respect to Taxes:

(i) that would not have been imposed but for the Holder or the beneficial owner of such Note (or a fiduciary, settlor, beneficiary, member or shareholder of, or possessor of a power over, such Holder or beneficial owner, if such Holder or beneficial owner is an estate, trust,

-15-

partnership or corporation) being considered as having a present or former connection with a Relevant Jurisdiction (other than a connection arising solely as a result of the acquisition, ownership or disposition of the 2054 Notes, the receipt of any payment under or with respect to the 2054 Notes or the Note Guarantee, or the exercise or enforcement of any rights under or with respect to the 2054 Notes, the Note Guarantees or the Indenture), including, without limitation, such Holder or beneficial owner (or such fiduciary, settlor, beneficiary, member, shareholder or possessor) being or having been a citizen or resident thereof or treated as a resident thereof or domiciled therein or a national thereof or being or having been engaged in a trade or business therein or having or having had a permanent establishment therein;

(ii) that would not have been imposed but for the failure of the Holder or any other person to comply with certification, identification or information reporting requirements concerning the nationality, residence, identity or connection with the Relevant Jurisdiction of the Holder or beneficial owner, if compliance is required by statute, by regulation of the Relevant Jurisdiction or by an applicable income tax treaty to which the Relevant Jurisdiction is a party as a precondition to exemption from such Tax;

(iii) payable other than by withholding from payments of principal of or interest on the 2054 Notes or from payments in respect of the Note Guarantee;

(iv) that would not have been imposed but for a change in law, regulation or administrative or judicial interpretation that becomes effective more than 15 days after the payment becomes due or is duly provided for, whichever occurs later;

(v) that are estate, inheritance, gift, sales, excise, transfer, wealth, capital gains or personal property or similar Taxes;

(vi) required to be withheld by any Paying Agent from any payment of principal of or interest on any Note, if such payment can be made without such withholding by at least one other Paying Agent;

(vii) that would not have been imposed but for the presentation by the Holder of any 2054 Note, where presentation is required, for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof was duly provided for, whichever occurred later (except to the extent that the Holder would have been entitled to Additional Amounts had the 2054 Note been presented on the last day of such 30-day period);

(viii) that are imposed under Sections 1471 through 1474 of the Code as of the Issue Date (or any amended or successor provision that is substantively comparable), any current or future regulations or official interpretations thereof, any agreement entered into pursuant to Section 1471(b) of the Code as of the Issue Date (or any amended or successor provision that is substantively comparable) or any fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement entered into in connection with the implementation of such sections of the Code; or

(ix) in the case of any combination of clauses (i), (ii), (iii), (iv), (v), (vi), (vii) and (viii);

-16-

nor shall Additional Amounts be paid with respect to any payment of the principal of or interest, if any, on any 2054 Note or any payment in respect of a Note Guarantee to any such Holder who is a fiduciary or a partnership that is not the sole beneficial owner of such payment to the extent a beneficiary or settlor with respect to such fiduciary or a member of such partnership or the beneficial owner would not have been entitled to such Additional Amounts had it been the Holder of the 2054 Note.

(c) The Issuers, the Guarantor or the Paying Agent, as applicable, will (i) make any required withholding or deduction, and (ii) remit the full amount deducted or withheld by it to the Relevant Jurisdiction in accordance with applicable law.

(d) All references in the Indenture, other than in Section 2.01(r) of this First Supplemental Indenture and Sections 8.02, 8.03 and 8.06 of the Base Indenture, to the payment of the principal or interest, if any, on or the net proceeds received on the sale or exchange of, any 2054 Notes or any payment made under the Note Guarantee shall be deemed to include Additional Amounts to the extent that, in that context, Additional Amounts are, were or would be payable.

(e) In addition, the Issuers shall pay any present or future stamp, issue, registration, court, documentary, excise, property, or similar Taxes (i) imposed by any Relevant Jurisdiction in respect of the execution, issuance, delivery, or registration of the 2054 Notes, the Note Guarantee, the Indenture, or any other document or instrument referred to therein, or the receipt of any payments with respect to the 2054 Notes, or (ii) imposed by any jurisdiction in respect of the enforcement of the 2054 Notes, the Note Guarantee, the Indenture, or any other document or instrument referred to therein.

(f) The Issuers’ and the Guarantor’s respective obligations to pay Additional Amounts if and when due will survive the termination of the Indenture and the payment of all other amounts in respect of the 2054 Notes and shall apply mutatis mutandis to any successor of either of the Issuers or the Guarantor, and to any jurisdiction (other than the United States or any state thereof or the District of Columbia, or any political subdivision of any such state or the District of Columbia, or taxing authority or agency thereof or therein) in which such successor is incorporated, organized, engaged in business or otherwise resident for tax purposes, and any political subdivision or governmental authority thereof or therein.

Section 7.02. Tax Treatment. On the Issue Date, all or a portion of the proceeds of the offering of the 2054 Notes will be borrowed by the Co-Obligor and the remaining portion of the proceeds of the offering of the 2054 Notes, if any, will be borrowed by the Issuer. The portion of the proceeds of the 2054 Notes that will be borrowed by the Co-Obligor and the portion of the proceeds of the 2054 Notes that will be borrowed by the Issuer, in each case, on the Issue Date, and after any subsequent change to such allocation, shall be made available by the Issuers to any Holder or beneficial owner upon request to Aptiv Investor Relations (including through the Issuer’s website or at ***@***). Notwithstanding the foregoing or anything to the contrary herein, (x) each Holder and beneficial owner acknowledge that the Co-Obligor and the Issuer have the right to change the foregoing allocations between the Co-Obligor and the Issuer for any reason (including, but not limited, as a result of a redemption of any 2054 Notes or the issuance of Additional 2054 Notes, in each case, in a different allocation than the initial allocation with respect to the outstanding 2054 Notes), and (y) the Issuers are entitled (i) not to treat any Additional 2054 Notes that have a different allocation than the initial allocation with respect to the outstanding 2054 Notes as non-fungible for U.S. federal income tax purposes solely as a result of such different allocation, and (ii) to treat the issuance of Additional 2054 Notes as resulting in a change in the allocation of the outstanding 2054 Notes so as to have the same allocation across the Additional 2054 Notes and the outstanding 2054 Notes.

6.875% Subordinated Note due 2054

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

1. INTEREST. Aptiv PLC (the “Issuer”) and Aptiv Global Financing Designated Activity Company (the “Co-Obligor” and, together with the Issuer, the “Issuers”) promise to pay (subject to deferral as set forth herein) interest on the principal amount of this 2054 Note (i) from and including the date of the original issuance to, but excluding, December 15, 2029 at an annual rate of 6.875% and (ii) from and including December 15, 2029 during each Interest Reset Period at an annual rate equal to the Five-Year Treasury Rate as of the most recent Reset Interest Determination Date, plus 3.385%. The 2054 Notes will mature on December 15, 2054. Interest will accrue from September 13, 2024 and will, subject to the Company’s right to defer interest payments (as described in Article 4), be payable semi-annually in arrears on June 15 and December 15 of each year, commencing on June 15, 2025, or, if any such day is not a Business Day, on the next succeeding Business Day (each, an “Interest Payment Date”). If interest payments are deferred or otherwise not paid, they will accrue and compound until paid at the same rate at which the 2054 Notes bear interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the 2054 Notes) to the extent permitted by law. As permitted by the terms of the 2054 Notes, if interest payments are deferred or otherwise not paid up to a redemption date that does not fall on an Interest Payment Date, they will accrue and compound until paid at the same rate at which the 2054 Notes bear interest (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the 2054 Notes) to the extent permitted by law. The amount of interest payable for any interest accrual period will be computed on the basis of a 360-day year consisting of twelve 30-day months. The amount of interest payable for any period shorter than a full semi-annual period for which interest is computed will be computed on the basis of the number of days in the period using 30-day calendar months. All references to “interest” on the 2054 Notes and, insofar as it relates to the 2054 Notes, this Indenture, shall be deemed to include semi-annual interest payments and applicable interest on interest payments accrued but not paid on the applicable Interest Payment Date.

2. METHOD OF PAYMENT. The Issuers will pay interest on this 2054 Note to the Person who is the registered Holder of this 2054 Note at the close of business on the Record Date (whether or not a Business Day) next preceding the Interest Payment Date, even if this 2054 Note is cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.13 of the Base Indenture with respect to defaulted interest. Payment of interest may be made by check mailed to the Holders at their addresses set forth in the Note Register of Holders, provided that (a) all payments of principal, premium, if any, and interest on, 2054 Notes represented by Global Notes registered in the name of or held by the DTC or its nominee will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof and (b) all payments of principal, premium, if any, and interest with respect to Certificated Notes will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Paying Agent may accept in its discretion). Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debt.

3. AUTHENTICATING AGENT, PAYING AGENT AND REGISTRAR. Initially, Deutsche Bank Trust Company Americas will act as Authenticating Agent, Paying Agent and Registrar.

The Issuers may change any Authenticating Agent, Paying Agent or Registrar without notice to the Holders. Aptiv International Holdings (UK) LLP or any of its Subsidiaries may act in any such capacity.

The Issuers shall be entitled to issue Additional 2054 Notes pursuant to the Base Indenture. The terms of the 2054 Notes include those stated in the Base Indenture and those made part of the Base Indenture by reference to the first supplemental indenture, among the Issuers, the Guarantor, the Trustee and the Registrar and Paying Agent, dated as of September 13, 2024 (the “First Supplemental Indenture” and together with the Base Indenture, the “Indenture”), setting forth the additional terms of the 2054 Notes pursuant to Section 2.03 of the Indenture and the provisions of the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The 2054 Notes are subject to all such terms, and Holders are referred to the Indenture and the Trust Indenture Act for a statement of such terms. To the extent any provision of this 2054 Note conflicts with the express provisions of the Indenture and those other provisions forming a part thereof with respect to the 2054 Notes, the provisions of the Indenture and such other provisions with respect to the 2054 Notes shall govern and be controlling.

In such case, the Issuers will deliver a notice of redemption specifying the tax event redemption date within 120 days after the occurrence of a Tax Event.

8. REDEMPTION FOLLOWING A CHANGE IN TAX LAW RELATING TO OBLIGATION TO PAY ADDITIONAL AMOUNTS. The Issuers may redeem the 2054 Notes as a whole but not in part, at their option at any time prior to maturity, upon the giving of a written notice of redemption to the Holders, with a copy to the Trustee and the Paying Agent, if the Issuers determine that, as a result of:

The Paying Agent and Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and the Issuers may require Holders to pay any transfer tax or other similar governmental charge payable in connection with such transfer and exchange that are required by law or permitted by the Indenture. The Registrar shall not be required to register the transfer of or exchange of (a) any 2054 Note selected for redemption in whole or in part pursuant to Article 3 of the Base Indenture, except the unredeemed portion of any such 2054 Note being redeemed in part, or (b) any such 2054 Note for a period beginning 15 days before the mailing of a notice of an offer to repurchase or redeem such 2054 Notes or 15 days before an Interest Payment Date (whether or not an Interest Payment Date or other date determined for the payment of interest), and ending on such mailing date or Interest Payment Date, as the case may be.

13. PERSONS DEEMED OWNERS. The registered Holder of this 2054 Note may be treated as its owner for all purposes.

15. DEFAULTS AND REMEDIES. The Events of Default relating to the 2054 Notes are defined in Section 6.01 of the Base Indenture, as supplemented by Section 9.01 of the First Supplemental Indenture. If any Event of Default (other than an Event of Default described in clause (3) of Section 9.01 of the First Supplemental Indenture) occurs and is continuing, the Trustee or the Holders of at least 33% in principal amount of the then outstanding 2054 Notes and all other notes issued under the Indenture affected thereby (all such series voting as a single class) may declare the principal of and accrued but unpaid interest on all the 2054 Notes to be due and payable immediately by notice in writing to the Issuers and the Trustee (if given by the Holders) specifying the respective Event of Default and that it is a “notice of acceleration”, and the same shall become immediately due and payable. This right does not apply if an Event of Default described in clause (3) of Section 9.01 of the First Supplemental Indenture. If one of the Events of Default described in clause (3) of Section 9.01 of the First Supplemental Indenture occurs and is continuing, neither the Trustee nor the Holders of the 2054 Notes will be entitled to declare the principal amount of all 2054 Notes, together with accrued and unpaid interest thereon, to be due and payable immediately. Holders may not enforce the Indenture, the Note Guarantee or the 2054 Notes except as provided in the Indenture. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding 2054 Notes and all other notes of all series affected thereby may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing Default (except a Default relating to the payment of principal, premium, if any, or interest) if it determines that withholding notice is in their interest. The Holders of a majority in aggregate principal amount of the then outstanding 2054 Notes and all other notes issued under the Indenture affected thereby (all such series voting as a single class) by written notice to the Trustee may on behalf of the Holders of all of the 2054 Notes waive any existing Default and its consequences under the Indenture with respect to the 2054 Notes except a continuing Default in payment of the principal of, premium, if any, or interest on, any of the 2054 Notes held by a non-consenting Holder. The Issuers are required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Issuers are required within 30 Business Days after becoming aware of any Default with respect to the 2054 Notes, to deliver to the Trustee a statement specifying such Default and what action the Issuers propose to take with respect thereto.
