NOW, THEREFORE, in consideration of the agreements and obligations set forth herein and for other good and valuable consideration, the sufficiency of which is hereby acknowledged, the parties hereto hereby agree as follows:
ARTICLE I



2.875% SENIOR NOTES DUE 2023
Section 1.01    Establishment.  There is hereby established a new series of Securities to be issued under the Indenture, to be designated as the Corporation’s 2.875% Senior Notes due 2023 (the “2023 Notes”).


There are to be authenticated and delivered $350,000,000 principal amount of the 2023 Notes, and no further 2023 Notes shall be authenticated and delivered except as provided by Section 304, 305, 306, 906 or 1106 of the Original Indenture and the last paragraph of Section 301 thereof.  The 2023 Notes shall be issued in fully registered form without coupons.
The 2023 Notes shall be in substantially the form set out in Exhibit A hereto, and the form of the Trustee’s Certificate of Authentication for the 2023 Notes shall be in substantially the form set forth in Exhibit B hereto.
Each 2023 Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.
Section 1.02    Definitions.  The following defined terms used in this Article I shall, unless the context otherwise requires, have the meanings specified below for purposes of the 2023 Notes.  Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Original Indenture.


“Business Day” means any day other than a Saturday or Sunday that is neither a Legal Holiday nor a day on which banking institutions in New York, New York are authorized or required by law, regulation or executive order to close, or a day on which the Corporate Trust Office is closed for business.











“Interest Payment Date” means each April 18 and October 18 of each year, commencing on October 18, 2016.
“Legal Holiday” means any day that is a legal holiday in New York, New York.
“Original Issue Date” means April 18, 2016.

“Stated Maturity” means April 18, 2023.
Section 1.03    Payment of Principal and Interest.  The principal of the 2023 Notes shall be due at Stated Maturity (unless earlier redeemed).  The unpaid principal amount of the 2023 Notes shall bear interest at the rate of 2.875% per annum until paid or duly provided for, such interest to accrue from April 18, 2016 or from the most recent Interest Payment Date to which interest has been paid or duly provided for.  Interest shall be paid semi-annually in arrears on each Interest Payment Date to the Person or Persons in whose name the 2023 Notes are registered on the Regular Record Date for such Interest Payment Date; provided that interest payable at the Stated Maturity or on a Redemption Date as provided herein shall be paid to the Person to whom principal is payable.  Any such interest that is not so punctually paid or duly provided for shall forthwith cease to be payable to the Holders on such Regular Record Date and may either be paid to the Person or Persons in whose name the 2023 Notes are registered at the close of business on a Special Record Date for the payment of such defaulted interest to be fixed by the Trustee (“Special Record Date”), notice whereof shall be given to Holders of the 2023 Notes not less than ten (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 any securities exchange, if any, on which the 2023 Notes may be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.


Payments of interest on the 2023 Notes shall include interest accrued to but excluding the respective Interest Payment Dates.  Interest payments for the 2023 Notes shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months.  In the event that any date on which interest is payable on the 2023 Notes is not a Business Day, then payment of the interest payable on such date shall be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay) with the same force and effect as if made on the date the payment was originally payable.
Payment of principal of, premium, if any, and interest on the 2023 Notes shall 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.  Payments of principal of, premium, if any, and interest on 2023 Notes represented by a Global Security shall be made by wire transfer of immediately available funds to the Holder of such Global Security, provided that, in the case of payments of principal and premium, if any, such Global Security is first surrendered to the Paying Agent.  If any of the 2023 Notes are no longer represented by a Global Security, (i) payments of principal, premium, if any, and interest due at the Stated Maturity or earlier redemption of such 2023 Notes shall be made at the office of the Paying Agent upon surrender of such 2023 Notes to the Paying Agent and (ii) payments of interest shall be made, at the option of the Corporation, subject to such surrender where applicable, by (A) check mailed to the address of the Person entitled thereto as such address shall appear in the Security Register or (B) 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 Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto.
Section 1.04    Denominations.  The 2023 Notes shall be issued in denominations of $2,000 or any integral multiple of $1,000 in excess thereof.


Section 1.05     Global Securities.  The 2023 Notes shall initially be issued in the form of one or more Global Securities registered in the name of the Depositary (which initially shall be The Depository Trust Company) or its nominee.  The 2023 Notes will be initially issued pursuant to an exemption or exemptions from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”).  Beneficial interests in the 2023 Notes offered and sold to “qualified institutional buyers” (as defined in Rule 144A under the Securities Act) in reliance upon 











Rule 144A under the Securities Act shall be represented by one or more separate Global Securities (each, a “Rule 144A Global Note”).  Each Rule 144A Global Note shall bear the non-registration legend in substantially the form set forth in Exhibit A hereto (the “Rule 144A Legend”).  Beneficial interests in the 2023 Notes offered and sold to purchasers outside of the United States pursuant to Regulation S under the Securities Act shall be represented by one or more separate Global Securities (each, a “Regulation S Global Note”) and shall bear the Regulation S legend in substantially the form set forth in Exhibit A hereto (the “Regulation S Legend”).    


Except under the limited circumstances described below, 2023 Notes represented by such Global Security or Global Securities shall not be exchangeable for, and shall not otherwise be issuable as, 2023 Notes in definitive form.  The Global Securities described in this Article I may not be transferred except by the Depositary to a nominee of the Depositary or by a nominee of the Depositary to the Depositary or another nominee of the Depositary or to a successor Depositary or its nominee.  Nothing in the Indenture or the 2023 Notes shall be construed to require the Corporation to register any 2023 Note under the Securities Act, or to make any transfer of such 2023 Note in violation of applicable law.
A Global Security representing the 2023 Notes shall be exchangeable for 2023 Notes registered in the names of persons other than the Depositary or its nominee only if (i) the Depositary notifies the Corporation that it is unwilling or unable to continue as a Depositary for such Global Security and no successor Depositary shall have been appointed by the Corporation within 90 days of receipt by the Corporation of such notification, or if at any time the Depositary ceases to be a clearing agency registered under the Exchange Act at a time when the Depositary is required to be so registered to act as such Depositary and no successor Depositary shall have been appointed by the Corporation within 90 days after it becomes aware of such cessation, (ii) an Event of Default has occurred and is continuing with respect to the 2023 Notes and beneficial owners of a majority in aggregate principal amount of the 2023 Notes represented by Global Securities advise the Depositary to cease acting as Depositary, or (iii) the Corporation in its sole discretion, and subject to the procedures of the Depositary, determines that such Global Security shall be so exchangeable.  Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for 2023 Notes registered in such names as the Depositary shall direct.
A Rule 144A Global Note may not be transferred on the Security Register except in compliance with the restrictions on transfer contained in the Rule 144A Legend and upon receipt by the Security Registrar of a completed and executed Certificate of Transfer in the form contained in Exhibit C hereto.  Prior to the expiration of 40 days beginning on and including the later of (i) the day on which the offering of the 2023 Notes commences and (ii) the original issue date of the 2023 Notes, a Regulation S Global Note may not be transferred on the Security Register except in compliance with the restrictions on transfer contained in the Regulation S Legend and upon receipt by the Security Registrar of a completed and executed Certificate of Transfer in the form contained in Exhibit C hereto.    
Neither the Trustee or the Security Registrar shall have any obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Global Security (including any transfers between or among Depositary participants, members or holders of any Global Security) other than, in connection with a registration of transfer of the 2023 Note on the Security Register, to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.  Transfers of beneficial interests between a Rule 144A Global Note and a Regulation S Global Note, and other transfers relating to beneficial interests in the Global Securities, shall be reflected by endorsements of the Trustee, as custodian for DTC, on the schedules attached to such Rule 144A Global Note and Regulation S Global Note.  Neither the Corporation nor the Trustee shall have any liability for acts or omissions of any Depositary, for any Depositary records of beneficial interest, for any transactions between the Depositary, any participant member of the Depositary and/or beneficial owner of any interest in any 2023 Notes, or in respect of any transfers effected by the Depositary or by any participant member of the Depositary or any beneficial owner of any interest in any 2023 Notes held through any such participant member of the Depositary.











No service charge shall be made for any registration of transfer or exchange of the 2023 Notes, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.
Section 1.06    Redemption.  At any time and from time to time, the 2023 Notes shall be redeemable, in whole or in part, at the option of the Corporation, on any date (a “Redemption Date”), at a redemption price equal to the greater of (i) 100% of the principal amount of the 2023 Notes being redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to such Redemption Date) discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in either case, accrued and unpaid interest on the principal amount of the 2023 Notes being redeemed to, but excluding, such Redemption Date.


For purposes of this Section 1.06, the following terms have the following meanings:
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the 2023 Notes to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such 2023 Notes.
“Comparable Treasury Price” means, with respect to any Redemption Date for the 2023 Notes, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if fewer than three of such Reference Treasury Dealer Quotations are obtained, the average of all such Reference Treasury Dealer Quotations.
“Quotation Agent” means a Reference Treasury Dealer appointed by the Corporation.
“Reference Treasury Dealer” means Morgan Stanley & Co. LLC, plus two other financial institutions appointed by the Corporation at the time of any redemption of the 2023 Notes, or their respective affiliates or successors, each of which is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”); provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer, the Corporation will substitute therefor another Primary Treasury Dealer.
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the 2023 Notes, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.
“Treasury Rate” means, with respect to any Redemption Date for the 2023 Notes, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.  The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.
The Corporation shall notify the Trustee of the redemption price with respect to any redemption of the 2023 Notes promptly after the calculation thereof.  The Trustee shall not be responsible for calculating said redemption price.
If less than all of the 2023 Notes are to be redeemed, the Trustee shall select the 2023 Notes or portions of 2023 Notes to be redeemed by such method as the Trustee shall deem fair and appropriate.  The Trustee may select for redemption 2023 Notes and portions of 2023 Notes in amounts of $2,000 or any integral multiple of $1,000 in excess thereof.  As long as the 2023 Notes are represented by Global Securities, beneficial interests in such Notes shall be selected for redemption by the Depositary in accordance with its standard procedures therefor.











The 2023 Notes shall not have a sinking fund.
Section 1.07    Paying Agent.  The Trustee shall initially serve as Paying Agent with respect to the 2023 Notes, with the Place of Payment initially being the Corporate Trust Office.


Section 1.08    Legends.  Each 2023 Note, whether in a global form or in a definitive form, shall bear the Rule 144A Legend, or the Regulation S Legend, as applicable, in substantially the form set forth in Exhibit A hereto.

At any time and from time to time, at the option of the Corporation, the Securities of this series shall be redeemable, in whole or in part, on any date (a “Redemption Date”), at a redemption price equal to the greater of (i) 100% of the principal amount of the Securities of this series being redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to such Redemption Date) discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points, plus, in either case, accrued and unpaid interest on the principal amount being redeemed to, but excluding, such Redemption Date.
For purposes of the second preceding paragraph, the following terms have the following meanings:
“Comparable Treasury Issue” means the United States Treasury security selected by the Quotation Agent as having an actual or interpolated maturity comparable to the remaining term of the Securities of this series to be redeemed  that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Securities of this series.
“Comparable Treasury Price” means, with respect to any Redemption Date for the Securities of this series, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if fewer than three of such Reference Treasury Dealer Quotations are obtained, the average of all such Reference Treasury Dealer Quotations.
“Quotation Agent” means a Reference Treasury Dealer appointed by the Corporation.











“Reference Treasury Dealer” means Morgan Stanley & Co. LLC, plus two other financial institutions appointed by the Corporation at the time of any redemption of the Securities of this series, or their respective affiliates or successors, each of which is a primary U.S. Government securities dealer in the United States (a “Primary Treasury Dealer”); provided, however, that if any of the foregoing or their affiliates or successors shall cease to be a Primary Treasury Dealer, the Corporation will substitute therefor another Primary Treasury Dealer.
“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any Redemption Date for the Securities of this series, the average, as determined by the Quotation Agent, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Quotation Agent by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.
“Treasury Rate” means, with respect to any Redemption Date for the Securities of this series, the rate per annum equal to the semi-annual equivalent yield to maturity or interpolated maturity (on a day count basis) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.  The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.
The Corporation shall notify the Trustee of the redemption price with respect to any redemption of the Securities of this series promptly after the calculation thereof.  The Trustee shall not be responsible for calculating said redemption price.
Notice of any redemption by the Corporation will be mailed (or, as long as the Securities of this series are represented by one or more Global Securities, transmitted in accordance with the Depositary’s standard procedures therefor) at least 30 days but not more than 60 days before any Redemption Date to each Holder of Securities of this series to be redeemed.  If Notice of a redemption is provided and funds are deposited as required, interest will cease to accrue on and after the Redemption Date on the Securities of this series or portions of Securities of this series called for redemption.  In the event that any Redemption Date is not a Business Day, the Corporation will pay the redemption price on the next Business Day without any interest or other payment in respect of any such delay.  If less than all the Securities of this series are to be redeemed at the option of the Corporation, the Trustee shall select, in such manner as it shall deem fair and appropriate, the Securities of this series to be redeemed in whole or in part.  The Trustee may select for redemption Securities of this series and portions of the Securities of this series in amounts of $2,000 or any integral multiple of $1,000 in excess thereof.  As long as the Securities of this series are represented by Global Securities, beneficial interests in such Securities shall be selected for redemption by the Depositary in accordance with its standard procedures therefor.
In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the unredeemed portion hereof will be issued in the name of the Holder hereof upon the surrender hereof.
The Securities of this series shall not have a sinking fund.
The Securities of this series shall constitute the direct unsecured and unsubordinated debt obligations of the Corporation and shall rank equally in priority with the Corporation’s existing and future unsecured and unsubordinated indebtedness.
REFERENCE IS HEREBY MADE TO THE FURTHER PROVISIONS OF THIS SECURITY SET FORTH ON THE REVERSE HEREOF, WHICH FURTHER PROVISIONS SHALL FOR ALL PURPOSES HAVE THE SAME EFFECT AS IF SET FORTH AT THIS PLACE.
Unless the certificate of authentication hereon has been executed by the Trustee by manual signature, this Security shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

















IN WITNESS WHEREOF, the Corporation has caused this instrument to be duly executed as of April 18, 2016.

This Security is one of the series designated on the face hereof as 2.875% Senior Notes due 2023 initially in the aggregate principal amount of $350,000,000.  Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.
If an Event of Default with respect to the Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner, with the effect and subject to the conditions 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 Corporation and the rights of the Holders of the Securities of all series affected under the Indenture at any time by the Corporation and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (voting as one class).  The Indenture contains provisions permitting the Holders of not less than a majority in principal amount of the Outstanding Securities of all series with respect to which a default under the Indenture shall have occurred and be continuing (voting as one class), on behalf of the Holders of the Securities of all such series, to waive, with certain exceptions, such default under the Indenture and its consequences.  The Indenture also permits the Holders of not less than a majority 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 compliance by the Corporation with certain provisions of the Indenture affecting such series.  Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.
No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
