Indenture and the terms of such series may be described by a supplemental indenture executed by the Company and the Trustee; 
 WHEREAS, the
Company proposes to create under the Indenture a new series of Securities;

binding obligation of the Company have been done or performed. 
 NOW, THEREFORE, in consideration of the agreements and obligations set

series may be reopened at any time, without the consent of any Holder, for issuances of additional Series A Senior Notes. Any such additional Series A Senior Notes will have the same interest rate, maturity and other terms as those initially issued.
Further Series A Senior Notes may also be authenticated and delivered as provided by Sections 304, 305, 306, 905 or 1107 of the Base Indenture.

maturity comparable to the remaining term of the Series A Senior Notes to be redeemed (assuming, for this purpose, that the Series A Senior Notes matured on October 15, 2024) 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 in years and months of the Series A Senior Notes. 

“Comparable Treasury Price” for any Redemption Date means (i) the average of the Reference Treasury Dealer Quotations for such
Redemption Date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (ii) if the Independent Investment Banker obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

Indenture or provision therefor satisfactory to the Trustee has been made; 
 (iii) Series A Senior Notes with respect to which the Company
has effected defeasance or covenant defeasance pursuant to Section 402 of the Base Indenture, except to the extent provided in Section 402 of the Base Indenture; and

Series A Senior Notes have been authenticated and delivered pursuant to the Indenture, other than any such Series A Senior Notes in respect of which there shall have been presented to the Trustee proof satisfactory to it that such Series A Senior

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 in whose name the Series A Senior Notes are registered on the Regular Record Date

or duly provided for will 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 Series A Senior 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 (in accordance with Section 307 of the Base Indenture), notice whereof shall be given to Holders of the Series A Senior Notes not less than ten (10) days prior to

day that is a Business Day (and without any interest or payment in respect of any such delay), in each case with the same force and effect as if made on the date the payment was originally payable. 

Payment of the principal and interest on the Series A Senior Notes shall be made at the office of the Paying Agent 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 Series A Senior Notes, upon redemption or repurchase being made upon
surrender of such Series A Senior Notes to the Paying Agent. Payments of interest (including interest on any Interest Payment Date) will be made, subject to such surrender where applicable, at the option of the Company, (i) by check mailed to
the address of the Person entitled thereto as such address shall appear in the Security Register or (ii) 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
Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto. In the event that any date on which principal and interest is payable on the Series A Senior Notes is not a Business Day, then payment of the
principal and interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or payment in respect of any such delay), in each case with the same force and effect as if made on the date the
payment was originally payable. 
 Section 104. Denominations. The Series A Senior Notes may be issued in denominations of
$2,000, or any greater integral multiple of $1,000. 
 Section 105. Global Securities. The Series A Senior Notes will be
initially issued in the form of one or more Global Securities registered in the name of the Depositary (which shall be The Depository Trust Company) or its nominee. Except under the limited circumstances described below, Series A Senior Notes
represented by such Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series A Senior Notes in definitive form registered in names other than the Depositary or its nominee. The Global Securities described above
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. 

Owners of beneficial interests in such a Global Security will not be considered the Holders thereof for any purpose under the Indenture, and
no Global Security representing a Series A Senior Note shall be exchangeable, except for another Global Security of like denomination and tenor to be registered in the name of the Depositary or its nominee or to a successor Depositary or its nominee
or except as described below. The rights of Holders of such Global Security shall be exercised only through the Depositary. 

  
 5 













 A Global Security shall be exchangeable for Series A Senior Notes registered in the names of
persons other than the Depositary or its nominee only if (i) the Depositary notifies the Company 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
Company within 90 days of receipt by the Company 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 Company within 90 days after it becomes aware of such cessation, (ii) the Company in its sole discretion, and subject to the procedures of the Depositary, determines that
such Global Security shall be so exchangeable, in which case Series A Senior Notes in definitive form will be printed and delivered to the Depositary, or (iii) an Event of Default has occurred and is continuing with respect to the Series A
Senior Notes. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series A Senior Notes registered in such names as the Depositary shall direct. 

Section 106. Redemption. The Series A Senior Notes are redeemable, in whole or in part, at any time and from time to time prior to
October 15, 2024, at the option of the Company, at a Redemption Price equal to the greater of: 
 (i) 100% of the principal amount of
Series A Senior Notes then Outstanding to be so redeemed, or 
 (ii) the sum of the present values of the remaining scheduled payments of
principal and interest thereon (not including any portion of such payments of interest accrued as of the Redemption Date) discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year
consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, as calculated by an Independent Investment Banker, 

plus, in either of the above cases, accrued and unpaid interest thereon to the Redemption Date. In addition, the Series A Senior Notes are redeemable, in
whole or in part, at any time and from time to time on or after October 15, 2024 at the option of the Company, at a Redemption Price equal to 100% of the principal amount of the Series A Senior Notes then outstanding to be redeemed, plus
accrued and unpaid interest thereon to the Redemption Date. 
 The Adjusted Treasury Rate shall be calculated no later than the third
Business Day preceding the Redemption Date. 
 Unless the Company defaults in the payment of the Redemption Price, on and after the
Redemption Date, interest will cease to accrue on the Series A Senior Notes or portions thereof called for redemption. 
 In the event of
the redemption of the Series A Senior Notes in part only, a new Series A Senior Note or Notes for the unredeemed portion will be issued in the name or names of the Holders thereof upon surrender thereof. 

  
 6 













 The Company shall notify the Trustee in writing of the Redemption Price promptly after the
calculation thereof and the Trustee shall have no responsibility for such calculation. The notice of redemption shall be sent in accordance with the terms of the Base Indenture. 

Section 107. Sinking Fund; Conversion. The Series A Senior Notes shall not have a sinking fund. The Series A Senior Notes are not
convertible into or exchangeable for Equity Securities and/or any other securities. 
 Section 108. Additional Interest on Overdue
Amounts. Any principal of and installment of interest on the Series A Senior Notes that is overdue shall bear interest at the rate of 2.50% (to the extent that the payment of such interest shall be legally enforceable), from the dates such
amounts are due until they are paid or made available for payment, and such interest shall be payable on demand. 
 Section 109.
Paying Agent. The Trustee shall initially serve as Paying Agent with respect to the Series A Senior Notes, with the Place of Payment initially being the Corporate Trust Office.

Notes shall occur and be continuing, the principal of the Series A Senior 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 and the Trustee for the series of Securities affected, 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 Series A Senior Note shall be conclusive and binding
upon such Holder and upon all future Holders of this Series A Senior Note and of any Series A Senior 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 Series A Senior Note. 
 As provided in and subject to the provisions of the Indenture, the Holder of this Series A Senior
Note shall not have the right to institute any proceeding 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 Series A Senior Notes, the Holders of not less than a majority in principal amount of the Series A Senior 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 indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Series A Senior
Notes at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit
instituted by the Holder of this Series A Senior 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.

 No reference herein to the Indenture and no provision of this Series A Senior Note or of the
Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Series A Senior Note 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 Series A Senior Note
is registrable in the Security Register, upon surrender of this Series A Senior Note for registration of transfer at the office or agency of the Company in any place where the principal of, premium, if any, and interest on this Series A Senior Note
are payable, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or
more new Series A Senior Notes of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 

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

No service charge shall be made for any such registration of transfer or exchange, 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 Series A Senior 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 Series A Senior Note be overdue,
