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. 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 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 2021 Notes, 2024 Notes and 2028 Notes shall be in substantially the form of Exhibit A, Exhibit B and Exhibit C, respectively, hereto.

Interest on the 2024 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 2024 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 2024 Note attached hereto as Exhibit B) on the 2024 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.

(c) The 2028 Notes will mature on September 15, 2028 and will bear interest at the rate of 4.700% per annum, subject to adjustment upon the occurrence of certain ratings-based events with respect to the 2028 Notes as set forth under “Interest Rate Adjustment” in the form of 2028 Note attached hereto as Exhibit C. Interest on the 2028 Notes will be payable semi-annually, in cash, in arrears on March 15 and September 15 of each year, commencing on March 15, 2019, to the Holders thereof at the close of business on the immediately preceding March 1 and September 1 of each year. Interest on the 2028 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.

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 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.

The Company shall comply 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 the Change of Control Offer provisions of the Notes, 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.

Section 2.09. Additional Guarantees.

A-1

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 September 15, 2021 (the “Stated Maturity”), and to pay interest thereon at a variable rate, reset quarterly, from the date of original issuance or from the most recent Interest Payment Date to which interest has been paid or duly provided for until maturity. The Company will pay interest quarterly, in cash, in arrears on March 15, June 15, September 15 and December 15 of each year (each, an “Interest Payment Date”), commencing on December 15, 2018 (for the avoidance of doubt, such date shall be adjusted in accordance with the second paragraph of this Note). The per annum interest rate for the period from the Issue Date to but not including the first Interest Payment Date will be equal to three month LIBOR as determined on September 12, 2018, by the Calculation Agent, plus 1.05% per annum (the “Initial Interest Rate”) (subject to adjustment as set forth on the reverse of this Note under “Interest Rate Adjustment”). Following the initial Interest Period, the per annum interest rate on the Notes for each subsequent Interest Period will be equal to three month LIBOR as determined on the related Interest Determination Date, by the Calculation Agent, plus 1.05% (subject to adjustment as set forth on the reverse of this Note under “Interest Rate Adjustment”).The interest rate applicable to any day in a given Interest Period shall be either the Initial Interest Rate or the interest rate as reset on the Interest Determination Date immediately preceding the first day of such Interest Period (as the same may be adjusted as set forth on the reverse of the Note under “Interest Rate Adjustment”). Interest on the Notes shall accrue from the most recent Interest Payment Date on which interest has been paid or provided for or, if no interest has been paid or provided for, from September 14, 2018. The amount of interest on the Notes for each day that the Notes are outstanding (the “Daily Interest Amount”) shall be calculated by dividing the interest rate in effect for such day by 360 and multiplying the result by the principal amount of the Notes outstanding on such day. The amount of interest to be paid on the Notes for each Interest Period shall be calculated by adding such Daily Interest Amounts for each day in such Interest Period.

If any Interest Payment Date for the Notes, other than the Stated Maturity, is on a day that is not a Business Day, the Interest Payment Date and the Interest Reset Date for the succeeding Interest Period shall be postponed to the next day that is a Business Day; provided that if such Business Day is in the next succeeding calendar month, the Interest Payment Date shall be the immediately preceding Business Day. If the Stated Maturity is on a day that is not a Business Day, the payment of interest and principal on the Notes 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 will accrue for the period from and after the Stated Maturity. If any Interest Payment Date other than the Stated Maturity is postponed as described herein, the amount of interest for the relevant Interest Period shall be adjusted accordingly.

All percentages resulting from any of the above calculations will be rounded, if necessary, to the nearest one hundred thousandth of a percentage point, with five one-millionths of a percentage point being rounded upwards (e.g., 8.986865% (or 0.08986865) being rounded to 8.98687% (or 0.0898687)) and all dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upwards).

^* Insert in Global Securities.

A-2

The interest rate on the Notes will in no event be (i) higher than the maximum rate permitted by New York law as the same may be modified by United States laws of general application or (ii) less than zero.

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 March 1, June 1, September 1, December 1, 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 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.

Solely for purposes of determining the interest rate payable on the Notes, the following definitions shall apply:

“Business Day” means any day, other than a Saturday or Sunday, that is not a day on which banking institutions in any of the city of New York, New York or a place of payment are authorized or required by law or executive order to close.

“Daily Interest Amount” means the amount of interest for each day that the Notes are outstanding.

“Interest Determination Date” means, for any Interest Period, the second London Banking Day preceding the applicable Interest Reset Date for such Interest Period.

“Interest Period” means the period from, and including, an Interest Payment Date to, but excluding, the next succeeding Interest Payment Date, except for the initial Interest Period, which shall be the period from, and including, Issue Date to, but excluding the Interest Payment Date occurring on December 15, 2018 (for the avoidance of doubt, such date shall be adjusted in accordance with the second paragraph of this Note).

“LIBOR” means the London Interbank Offered Rate, as determined by the Calculation Agent in accordance with the following:

(1) With respect to any Interest Determination Date, LIBOR will be the rate for deposits in United States dollars having a maturity of three months commencing on the first day of the applicable Interest Period that appears on Reuters Screen LIBOR01 Page as of 11:00 a.m., London time, on that Interest Determination Date. If no rate appears, then LIBOR, in respect of that Interest Determination Date, will be determined in accordance with the provisions set forth in (2) and (3) below;

A-3

(2) With respect to an Interest Determination Date on which no rate appears on Reuters Screen LIBOR01 Page, except as provided in clause (3) below, as specified in (1) above, the Company will request the principal London offices of each of four major reference banks in the London interbank market, as selected by the Company, to provide the Company with its offered quotation for deposits in United States dollars for the period of three months, commencing on the first day of the applicable Interest Period, to prime banks in the London interbank market at approximately 11:00 a.m., London time, on that Interest Determination Date and in a principal amount that is representative for a single transaction in United States dollars in that market at that time. If at least two quotations are provided, then LIBOR on that Interest Determination Date will be the arithmetic mean of those quotations as calculated by the Company and provided to the Calculation Agent. If fewer than two quotations are provided, then LIBOR on the Interest Determination Date will be the arithmetic mean, as calculated by the Company and provided to the Calculation Agent, of the rates quoted at approximately 11:00 a.m., in the City of New York, on the Interest Determination Date by three major banks in the City of New York selected by the Company for loans in United States dollars to leading European banks, having a three-month maturity and in a principal amount that is representative for a single transaction in United States dollars in that market at that time; provided, however, that if the banks selected by the Company are not providing quotations in the manner described by this sentence, LIBOR will be the same as the rate determined for the immediately preceding Interest Reset Date.

(3) Notwithstanding clause (2) above, if the Company or the Calculation Agent determine that LIBOR has been permanently discontinued, the Calculation Agent will use, in consultation with the Company, as a substitute for LIBOR (the ‘‘Alternative Rate’’) and for each future Interest Determination Date, the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with accepted market practice. As part of such substitution, the Calculation Agent will, after consultation with the Company, make such adjustments (‘‘Adjustments’’) to the Alternative Rate or the spread thereon, as well as the business day convention, Interest Determination Dates and related provisions and definitions, in each case that are consistent with accepted market practice for the use of such Alternative Rate for debt obligations such as the Notes. If the Calculation Agent determines, and following consultation with the Company, that there is no clear market consensus as to whether any rate has replaced LIBOR in customary market usage, the Calculation Agent shall have the right to resign as Calculation Agent in respect of the Notes and the Company will appoint a successor Calculation Agent in respect of the Notes, as provided in the applicable Calculation Agent agreement, between the Company and Xxxxx Fargo Bank, National Association, to determine the Alternative Rate and make any Adjustments thereon, and whose determinations will be binding on the Company, the Trustee and the Holders. If, however, the existing Calculation Agent or any subsequent Calculation Agent determines that LIBOR has been discontinued, but for any reason an Alternative Rate has not been determined, LIBOR will be equal to such rate on the Interest Determination Date when LIBOR was last available on the Reuters Screen LIBOR01 Page, as determined by the Calculation Agent.

REVERSE OF SENIOR NOTE

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture dated as of August 8, 2013, as supplemented by a Second Supplemental Indenture dated as of November 3, 2016 (together, the “Original Indenture”) and a Ninth Supplemental Indenture dated as of September 14, 2018 (the “Supplemental Indenture,” the Original Indenture, as supplemented by the Supplemental Indenture and as further amended or supplemented from time to time, herein called the “Indenture,” which term shall have the meaning assigned to it in such instrument), among the Company, the Guarantors (as defined in the Indenture) and Xxxxx Fargo Bank, National Association, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, 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 Security is one of the series designated on the face hereof (the “Notes”) which is unlimited in aggregate principal amount.

The Notes are redeemable, in whole or in part, at the times, in the manner and with the effect provided in the Indenture.

If an Event of Default with respect to the Notes shall occur 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.

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 to be affected under the Indenture at any time by the Company, the Guarantors and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time outstanding, on behalf of the Holders of all Securities of such series, to waive certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

As provided in and subject to the provisions of the Indenture, the Holder of this Note shall not have the right to institute, or to order or direct the Trustee to institute, any proceeding, judicial or otherwise, with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Notes, the Holders of not less than 25% in aggregate principal amount of the Notes at the time outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee security or indemnity reasonably satisfactory to it against the costs, expenses and liabilities to be incurred or reasonably probable to be incurred in compliance with such request, the Trustee for 60 days after its receipt of such notice, request and offer of indemnity has failed to institute any such proceeding and no direction inconsistent with such written request has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the outstanding Notes. The foregoing shall not apply to any suit instituted by the Holder of this Note for the enforcement of any payment of principal hereof or premium, if any, or interest hereon on or after the respective due dates expressed or provided for herein.

A-8

No reference herein to the Indenture and no provision of the Notes or of the Indenture shall alter or impair the obligation of the Company or any Guarantor, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on the Notes at the times, place and rate, and in the coin or currency, herein prescribed.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registrable with the Registrar, upon surrender of this Note for registration of transfer at the office or agency of the Registrar or the Company in a place for payment for this Note, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes having the same Stated Maturity and of like tenor of any authorized denominations as requested by the Holder upon surrender of the Note or Notes to be exchanged at the office or agency of the Registrar or the Company.

No service charge shall be made for any such registration of transfer or exchange of the Notes, 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 Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Company, the Trustee and any such agent shall be affected by notice to the contrary.

All terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.

Interest Rate Adjustment

The interest rate payable on the Notes will be subject to adjustments from time to time if either Xxxxx’x Investors Service, Inc., a subsidiary of Xxxxx’x Corporation, and its successors (“Moody’s”) or S&P Global Ratings, a division of S&P Global Inc., and its successors (“S&P”) or, if either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available, in each case for reasons outside of the control of the Company, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Moody’s or S&P, or both of them, as the case may be (a “Substitute Rating Agency”), downgrades (or downgrades and subsequently upgrades) the credit rating assigned to the Notes, in the manner described below.

A-9

If the rating assigned by Moody’s (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the then-applicable interest rate on the Notes, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “S&P Rating Percentage”):

Xxxxx’x Rating*	Percentage

Ba1	0.25%
Ba2	0.50%
Ba3	0.75%
B1 or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If the rating assigned by S&P (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the then-applicable interest rate on the Notes, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “Xxxxx’x Rating Percentage”):

S&P Rating*	Percentage

BB+	0.25%
BB	0.50%
BB-	0.75%
B+ or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If at any time the interest rate on the Notes has been increased and either Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently upgrades its rating of the Notes to any of the ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the Notes equals the then-applicable interest rate on the Notes plus the percentages set forth opposite the ratings from the tables above in effect immediately following the upgrade in rating. If Moody’s (or any Substitute Rating Agency therefor) subsequently upgrades its rating of the Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, and S&P (or any Substitute Rating Agency therefor) upgrades its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Notes will be decreased to then-applicable interest rate on the Notes (and if one such upgrade occurs and the other does not, the interest rate on the Notes will be decreased so that it does not reflect any increase attributable to the upgrading rating agency). In addition, the interest rates on the Notes will permanently cease to be subject to any adjustment described herein (notwithstanding any subsequent downgrade in the ratings by either or both rating agencies) if the Notes become rated Baa1 and BBB+ (or, in either case, the equivalent thereof, in the case of a Substitute Rating Agency) or higher by Moody’s and S&P (or, in either case, a Substitute Rating Agency therefor), respectively (or one of these ratings if the Notes are only rated by one rating agency).

A-10

Each adjustment required by any downgrade or upgrade in a rating set forth above, whether occasioned by the action of Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor), shall be made independent of any and all other adjustments. In no event shall (1) the interest rate for the Notes be reduced to below the then-applicable interest rate on the Notes or (2) the total increase in the interest rate on the Notes exceed 2.00% above the then-applicable interest rate on the Notes Any adjustment to the interest rate will be made independently of the quarterly adjustment to the interest rate on the Notes. In this section, the term “then-applicable interest rate” on the Notes means the interest rate determined in accordance with the Indenture without giving effect to any adjustment as described herein.

No adjustments in the interest rate of the Notes shall be made solely as a result of a rating agency ceasing to provide a rating of the Notes. If at any time Moody’s or S&P ceases to provide a rating of the Notes, the Company will use its commercially reasonable efforts to obtain a rating of the Notes from a Substitute Rating Agency, if one exists, in which case, for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last rating agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative rating scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate on the Notes will increase or decrease, as the case may be, such that the interest rate equals the then-applicable interest rate on the Notes plus the appropriate percentage, if any, set forth opposite the deemed equivalent rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other rating agency).

For so long as only one rating agency provides a rating of the Notes, any subsequent increase or decrease in the interest rate of the Notes necessitated by a reduction or increase in the rating by the rating agency providing the rating shall be twice the applicable percentage set forth in the applicable table above. For so long as neither Moody’s nor S&P (nor, in either case, a Substitute Rating Agency therefor) provides a rating of the Notes, the interest rate on the Notes will increase to, or remain at, as the case may be, 2.00% above the then-applicable interest rate on the Notes.

A-11

Any interest rate increase or decrease described above will take effect from the first Interest Payment Date following the date on which a rating change occurs that requires an adjustment in the interest rate. As such, interest will not accrue at such increased or decreased rate until the next Interest Payment Date following the date on which a rating change occurs. If Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor) changes its rating of the notes of the applicable series more than once prior to any particular Interest Payment Date, the last change by such agency prior to such Interest Payment Date will control for purposes of any interest rate increase or decrease with respect to the Notes described above relating to such rating agency’s action. If the interest rate payable on the Notes is increased as described above, the term “interest,” as used with respect to the Notes, will be deemed to include any such additional interest unless the context otherwise requires.

The Company will advise the Trustee and the holders of any occurrence of a rating change that requires an interest rate increase or decrease described above within five Business Days.

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 March 15, 2024 (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 March 15 and September 15 of each year (each, an “Interest Payment Date”), commencing on March 15, 2019, at a rate of 4.150% per annum (subject to adjustment as set forth on the reverse of this Note under “Interest Rate Adjustment”) 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 March 1 or September 1, 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 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.

Interest Rate Adjustment

B-7

If the rating assigned by Moody’s (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the interest rate payable on the Notes on the date of initial issuance, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “S&P Rating Percentage”):

Xxxxx’x Rating*	Percentage

Ba1	0.25%
Ba2	0.50%
Ba3	0.75%
B1 or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If the rating assigned by S&P (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the interest rate payable on the Notes on the date of initial issuance, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “Xxxxx’x Rating Percentage”):

S&P Rating*	Percentage

BB+	0.25%
BB	0.50%
BB-	0.75%
B+ or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If at any time the interest rate on the Notes has been increased and either Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently upgrades its rating of the Notes to any of the ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the Notes equals the interest rate payable on the Notes on the date of initial issuance plus the percentages set forth opposite the ratings from the tables above in effect immediately following the upgrade in rating. If Moody’s (or any Substitute Rating Agency therefor) subsequently upgrades its rating of the Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, and S&P (or any Substitute Rating Agency therefor) upgrades its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Notes will be decreased to interest rate payable on the Notes on the date of initial issuance (and if one such upgrade occurs and the other does not, the interest rate on the Notes will be decreased so that it does not reflect any increase attributable to the upgrading rating agency). In addition, the interest rates on the Notes will permanently cease to be subject to any adjustment described herein (notwithstanding any subsequent downgrade in the ratings by either or both rating agencies) if the Notes become rated Baa1 and BBB+ (or, in either case, the equivalent thereof, in the case of a Substitute Rating Agency) or higher by Moody’s and S&P (or, in either case, a Substitute Rating Agency therefor), respectively (or one of these ratings if the Notes are only rated by one rating agency).

B-8

No adjustments in the interest rate of the Notes shall be made solely as a result of a rating agency ceasing to provide a rating of the Notes. If at any time Moody’s or S&P ceases to provide a rating of the Notes, the Company will use its commercially reasonable efforts to obtain a rating of the Notes from a Substitute Rating Agency, if one exists, in which case, for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last rating agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative rating scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate on the Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate payable on the Notes on the date of initial issuance plus the appropriate percentage, if any, set forth opposite the deemed equivalent rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other rating agency).

The Company will advise the Trustee and the holders of any occurrence of a rating change that requires an interest rate increase or decrease described above within five Business Days.

The interest rate payable on the Notes will be subject to adjustments from time to time if either Xxxxx’x Investors Service, Inc., a subsidiary of Moody’s Corporation, and its successors (“Moody’s”) or S&P Global Ratings, a division of S&P Global Inc., and its successors (“S&P”) or, if either of Moody’s or S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available, in each case for reasons outside of the control of the Company, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by the Company (as certified by a resolution of the Board of Directors) as a replacement agency for Moody’s or S&P, or both of them, as the case may be (a “Substitute Rating Agency”), downgrades (or downgrades and subsequently upgrades) the credit rating assigned to the Notes, in the manner described below.

C-7

If the rating assigned by Moody’s (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the interest rate payable on the Notes on the date of initial issuance, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “S&P Rating Percentage”):

Xxxxx’x Rating*	Percentage

Ba1	0.25%
Ba2	0.50%
Ba3	0.75%
B1 or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If the rating assigned by S&P (or any Substitute Rating Agency therefor) of the Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Notes will increase from the interest rate payable on the Notes on the date of initial issuance, by an amount equal the percentage set forth opposite the rating in the table below (plus, if applicable, the percentage set forth opposite the rating in the table under “Xxxxx’x Rating Percentage”):

S&P Rating*	Percentage

BB+	0.25%
BB	0.50%
BB-	0.75%
B+ or below	1.00%
* Including the equivalent ratings of any Substitute Rating Agency.

If at any time the interest rate on the Notes has been increased and either Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently upgrades its rating of the Notes to any of the ratings set forth above, the interest rate on the Notes will be decreased such that the interest rate for the Notes equals the interest rate payable on the Notes on the date of initial issuance plus the percentages set forth opposite the ratings from the tables above in effect immediately following the upgrade in rating. If Moody’s (or any Substitute Rating Agency therefor) subsequently upgrades its rating of the Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, and S&P (or any Substitute Rating Agency therefor) upgrades its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Notes will be decreased to interest rate payable on the Notes on the date of initial issuance (and if one such upgrade occurs and the other does not, the interest rate on the Notes will be decreased so that it does not reflect any increase attributable to the upgrading rating agency). In addition, the interest rates on the Notes will permanently cease to be subject to any adjustment described herein (notwithstanding any subsequent downgrade in the ratings by either or both rating agencies) if the Notes become rated Baa1 and BBB+ (or, in either case, the equivalent thereof, in the case of a Substitute Rating Agency) or higher by Moody’s and S&P (or, in either case, a Substitute Rating Agency therefor), respectively (or one of these ratings if the Notes are only rated by one rating agency).

C-8

No adjustments in the interest rate of the Notes shall be made solely as a result of a rating agency ceasing to provide a rating of the Notes. If at any time Moody’s or S&P ceases to provide a rating of the Notes, the Company will use its commercially reasonable efforts to obtain a rating of the Notes from a Substitute Rating Agency, if one exists, in which case, for purposes of determining any increase or decrease in the interest rate on the Notes pursuant to the tables above (a) such Substitute Rating Agency will be substituted for the last rating agency to provide a rating of the Notes but which has since ceased to provide such rating, (b) the relative rating scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith by an independent investment banking institution of national standing appointed by us and, for purposes of determining the applicable ratings included in the applicable table above with respect to such Substitute Rating Agency, such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table and (c) the interest rate on the Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate payable on the Notes on the date of initial issuance plus the appropriate percentage, if any, set forth opposite the deemed equivalent rating from such Substitute Rating Agency in the applicable table above (taking into account the provisions of clause (b) above) (plus any applicable percentage resulting from a decreased rating by the other rating agency).

The Company will advise the Trustee and the holders of any occurrence of a rating change that requires an interest rate increase or decrease described above within five Business Days.
