In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the (y) the 2030 Notes Par Call Date in the case of the 2030 Notes or (z) the 2035 Notes Par Call Date in the case of the 2035 Notes (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields—one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life—and shall interpolate to the 2030 Notes Par Call Date or the 2035 Notes Par Call Date, as applicable, on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date.
If on the third Business Day preceding the redemption date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity that is closest to, the 2030 Notes Par Call Date or the 2035 Notes Par Call Date, as applicable.

If there are two or more United States Treasury securities maturing on the 2030 Notes Par Call Date or the 2035 Notes Par Call Date, as applicable, or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.
7

“Trigger Period” has the meaning assigned to such term in the definition of Change of Control Triggering Event.

ESTABLISHMENT OF SECURITIES
The following provisions of this Article 2 and certain provisions of Article 3 are made pursuant to Section 2.2 of the Original Indenture in order to establish and set forth the terms of the series of Securities described in Section 2.01.
Section 2.01. Title of Securities.
There is hereby established the following two series of Securities designated the (i) “4.900% Senior Notes due 2030” (the “2030 Notes”) and (ii) “5.500% Senior Notes due 2035” (the “2035 Notes”, and together with the 2030 Notes, the “Notes”).
Section 2.02. Aggregate Principal Amount of Notes.
There are initially to be authenticated and delivered (i) $500,000,000 principal amount of the 2030 Notes and (ii) $750,000,000 principal amount of the 2035 Notes. Such principal amount of the Notes of each series may be increased from time to time pursuant to Section 2.2 of the Original Indenture.
8

All Notes of each series need not be issued at the same time and any such series may be reopened at any time, without the consent of any Holder, for issuances of additional Notes of such series. Any such additional Notes of a particular series will have the same ranking, interest rate, maturity date, redemption rights and other terms as the Notes of such series initially issued, other than the issue date, the issue price and, if applicable, the first interest payment date and the first date from which interest will accrue. Any such additional Notes of a particular series, together with the Notes of such series initially issued, will constitute a single series of Securities under the Indenture; provided, however, that if such additional Notes of a particular series are not fungible for U.S. federal income tax purposes with the originally issued Notes of such series, such additional Notes shall be issued under a separate CUSIP number.
Nothing contained in this Section 2.02 or elsewhere in this Supplemental Indenture, or in the Notes, is intended to or shall limit execution by the Company or the Guarantors or authentication or delivery by the Series Trustee of Notes under the circumstances contemplated by Sections 2.7, 2.8, 2.11 and 9.6 of the Original Indenture.
The Notes shall be issued in registered form without coupons. The 2030 Notes and 2035 shall be in substantially the form of Exhibit A and Exhibit B, respectively, hereto. The form of the Series Trustee’s certificate of authentication for the Notes shall be in substantially the form set forth in the form of Note for each series attached hereto. Each Note shall be dated the date of authentication thereof. The entire initially issued principal amount of the Notes of each series shall initially be evidenced by one or more Global Securities registered in the name of the Depositary. The Notes shall not be issuable in definitive form except under limited circumstances specified in Section 2.14 of the Original Indenture.
Section 2.03. Payment of Principal and Interest on the Notes.
(a) The 2030 Notes will mature on May 29, 2030. If May 29, 2030 is not a Business Day, the related payment of interest and principal on such maturity date shall be made on the next succeeding Business Day, as if it were made on the date such payment was due, and no interest on such payment shall accrue for the period from and after May 29, 2030. The 2030 Notes shall bear interest at the rate of 4.900% per annum. Interest on the 2030 Notes will be payable semi-annually, in cash, in arrears on May 29 and November 29 of each year, commencing on November 29, 2025, to the Holders thereof at the close of business on the immediately preceding May 15 and November 15 of each year. Interest on the 2030 Notes will accrue from and including the most recent date to which interest has been paid or provided for or, if no interest has been paid or provided for, from and including the Issue Date. Interest on the 2030 Notes will be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date (as defined in the form of 2030 Note attached hereto as Exhibit A) on the 2030 Notes is not a Business Day, the payment of interest will be made on the next succeeding Business Day and no additional interest will accrue on the amount so payable for the period from and after such Interest Payment Date to the next succeeding Business Day.
9

(b) The 2035 Notes will mature on May 29, 2035. If May 29, 2035 is not a Business Day, the related payment of interest and principal on such maturity date shall be made on the next succeeding Business Day, as if it were made on the date such payment was due, and no interest on such payment shall accrue for the period from and after May 29, 2035. The 2035 Notes shall bear interest at the rate of 5.500% per annum. Interest on the 2035 Notes will be payable semi-annually, in cash, in arrears on May 29 and November 29 of each year, commencing on November 29, 2025, to the Holders thereof at the close of business on the immediately preceding May 15 and November 15 of each year. Interest on the 2035 Notes will accrue from and including the most recent date to which interest has been paid or provided for or, if no interest has been paid or provided for, from and including the Issue Date. Interest on the 2035 Notes will be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date (as defined in the form of 2035 Note attached hereto as Exhibit B) on the 2035 Notes is not a Business Day, the payment of interest will be made on the next succeeding Business Day and no additional interest will accrue on the amount so payable for the period from and after such Interest Payment Date to the next succeeding Business Day.
Section 2.04. Denominations.
The Notes of each series will be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

(d) The calculation or determination of the redemption price shall be made by the Company or on its behalf by such Person as the Company shall designate. For the avoidance of doubt, the calculation or determination of the redemption price, including the determination of any Treasury Rate, shall not be the obligation or responsibility of the Series Trustee or Paying Agent.

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

Section 2.07. Offer to Repurchase Upon Change of Control Triggering Event.
Upon the occurrence of a Change of Control Triggering Event with respect to a series of Notes, unless the Company has exercised its right to redeem the Notes of the applicable series as set forth in Section 2.06(a), each Holder of the Notes of such series shall have the right to require the Company to purchase all or a portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such Holder’s Notes of such series as set forth in this Section 2.07 (the “Change of Control Offer”), at a purchase price equal to 101% of the aggregate principal amount thereof plus accrued and unpaid interest, if any, to, but excluding, the date of purchase.
Notwithstanding the foregoing, installments of interest on the Notes of a series that are due and payable on Interest Payment Dates falling on or prior to the Change of Control Payment Date (as defined below) will be payable on the applicable Interest Payment Date to the registered Holders as of the close of business on the relevant record date.
Within 30 days following the date upon which a Change of Control Triggering Event with respect to a series of Notes occurs or, at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company shall be required to deliver a written notice to each Holder of Notes of the applicable series at its registered address, with a copy to the Series Trustee, which written notice will govern the terms of the Change of Control Offer. Such written notice will state, among other things, the purchase date, which shall be no earlier than 30 days nor later than 60 days from the date such written notice is delivered, other than as may be required by law (the “Change of Control Payment Date”). The written notice, if delivered prior to the date of consummation of the Change of Control, shall state that the Change of Control Offer is conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date. Holders of Notes of the applicable series electing to have such Notes repurchased pursuant to a Change of Control Offer shall be required to surrender their Notes of the applicable series, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the written notice, or transfer the Holder’s Notes of the applicable series to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.
The Company shall not be required to make a Change of Control Offer with respect to the Notes of a series if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer if it had been made by the Company, and such third party purchases all Notes of such series properly tendered and not withdrawn under its offer.
13

The Company shall comply in all material respects with the requirements, to the extent applicable, 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 Notes as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 2.07, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached the Company’s obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict.

Westinghouse Air Brake Technologies Corporation, a corporation organized and existing under the laws of the State of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [Cede & Co.]*, or registered assigns (the “Holder”), the principal sum of ($ ) on May 29, 2030 (the “Stated Maturity”), and to pay interest thereon from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, or if no interest has been paid or duly provided for, from and including the Issue Date, semi-annually, in cash, in arrears on May 29 and November 29 of each year (each, an “Interest Payment Date”), commencing on November 29, 2025, at a rate of 4.900% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note is registered at the close of business on the preceding May 15 or November 15, as applicable (each, a “Regular Record Date”) (whether or not a Business Day); provided that the interest payable at the Stated Maturity will be paid to the Person to whom principal is payable. Any such interest not so punctually paid or duly provided for 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 is registered at the close of business on a special record date for the payment of such defaulted interest to be fixed by the Series Trustee, notice of which shall be given to Holders of the Notes not less than 10 days prior to such special record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of the Depositary and any securities exchange or automated quotation system on which the Notes may be listed or traded, and upon such notice as may be required by the Depositary and such exchange or automated quotation system.
Payments of interest on the Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date falls on a day that is not a Business Day, the payment of the interest payable on such date will be made on the next succeeding Business Day, and no interest shall accrue on the amount of interest due on that Interest Payment Date for the period from and after such Interest Payment Date to the date of payment. If the Stated Maturity is not a Business Day, the related payment of interest and principal on such Stated Maturity shall be made on the next succeeding Business Day, as if it were made on the date such payment was due, and no interest on such payment shall accrue for the period from and after such Stated Maturity.

Westinghouse Air Brake Technologies Corporation, a corporation organized and existing under the laws of the State of Delaware (herein called the “Company,” which term includes any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to [Cede & Co.]*, or registered assigns (the “Holder”), the principal sum of ($ ) on May 29, 2035 (the “Stated Maturity”), and to pay interest thereon from the most recent Interest Payment Date (as defined below) to which interest has been paid or duly provided for, or if no interest has been paid or duly provided for, from and including the Issue Date, semi-annually, in cash, in arrears on May 29 and November 29 of each year (each, an “Interest Payment Date”), commencing on November 29, 2025, at a rate of 5.500% per annum until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in such Indenture, be paid to the Person in whose name this Note is registered at the close of business on the preceding May 15 or November 15, as applicable (each, a “Regular Record Date”) (whether or not a Business Day); provided that the interest payable at the Stated Maturity will be paid to the Person to whom principal is payable. Any such interest not so punctually paid or duly provided for 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 is registered at the close of business on a special record date for the payment of such defaulted interest to be fixed by the Series Trustee, notice of which shall be given to Holders of the Notes not less than 10 days prior to such special record date, or be paid at any time in any other lawful manner not inconsistent with the requirements of the Depositary and any securities exchange or automated quotation system on which the Notes may be listed or traded, and upon such notice as may be required by the Depositary and such exchange or automated quotation system.
Payments of interest on the Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Notes shall be computed on the basis of a 360-day year of twelve 30-day months. If any Interest Payment Date falls on a day that is not a Business Day, the payment of the interest payable on such date will be made on the next succeeding Business Day, and no interest shall accrue on the amount of interest due on that Interest Payment Date for the period from and after such Interest Payment Date to the date of payment. If the Stated Maturity is not a Business Day, the related payment of interest and principal on such Stated Maturity shall be made on the next succeeding Business Day, as if it were made on the date such payment was due, and no interest on such payment shall accrue for the period from and after such Stated Maturity.
Payment of the principal of and interest on the Notes will be made 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 debts, with any such payment that is due at the Stated Maturity of any Note being made upon surrender of such Note to a Paying Agent; provided, however, that payment of interest, subject to such surrender where applicable, (i) may be made at the Company’s option by check mailed to the address of the Person entitled thereto as such address shall appear in the records maintained by the Registrar or the Company and (ii) in the case of any Global Security, must be made by wire transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Series Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto.
