issued in one or more series under an Indenture, dated as of May 18, 2009, and a supplemental indenture relating to such series dated as of February 8, 2011 (herein, collectively called the “Indenture,” which term shall
have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., 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 Trustee and the Holders of the Securities and of the terms upon which the Notes are,
and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, such series initially limited in aggregate principal amount to $750,000,000; provided that the Company may at any time and from time to
time, without the consent of any Holder, issue additional Notes of this series. 
 The Notes of this series are not redeemable
at the option of the Company or the Holders. 
 The Notes of this series are not entitled to the benefit of any sinking fund.

 The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Notes of this series or
certain restrictive covenants and Events of Default with respect to such Notes, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of such Notes may be declared, or shall immediately become, 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 Notes of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Notes of each
series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent
or waiver by the Holders of Notes of this series shall be conclusive and binding upon such Holders and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor 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 Holders of the Notes of this series 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 Notes of this series, the Holders of not less than 25% in aggregate principal amount 

  
 A-5









 
of the Notes of this series 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
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of such 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 Note for the enforcement of any payment of principal hereof or any premium or interest
hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this 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 Note is
registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this 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 Notes of this series 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 of this series 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, Notes of this series are exchangeable for a like principal amount of Notes of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 

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
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 Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Note is a Global Security and
is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 305 thereof on transfers and exchanges of Global Securities. 

This Note and the Indenture shall be governed by, and construed in accordance with, the laws of the State of New York.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Notes”), issued and to be
issued in one or more series under an Indenture, dated as of May 18, 2009, and a supplemental indenture relating to such series dated as of February 8, 2011 (herein, collectively called the “Indenture,” which term shall
have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon Trust Company, N.A., 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 Trustee and the Holders of the Securities and of the terms upon which the Notes are,
and are to be, authenticated and delivered. This Note is one of the series designated on the face hereof, such series initially limited in aggregate principal amount to $500,000,000; provided that the Company may at any time and from time to
time, without the consent of any Holder, issue additional Notes of this series. 
 The Notes of this series are not redeemable
at the option of the Company or the Holders. 
 The Notes of this series are not entitled to the benefit of any sinking fund.

 The Indenture contains provisions for defeasance at any time of the entire indebtedness of the Notes of this series or
certain restrictive covenants and Events of Default with respect to such Notes, in each case upon compliance with certain conditions set forth in the Indenture. 
 If an Event of Default with respect to Notes of this series shall occur and be continuing, the principal of such Notes may be declared, or shall immediately become, 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 Notes of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a
majority in aggregate principal amount of the Notes at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Notes of each
series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent
or waiver by the Holders of Notes of this series shall be conclusive and binding upon such Holders and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor 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 Holders of the Notes of this series 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 Notes of this series, the Holders of not less than 25% in aggregate principal amount 

  
 B-5









 
of the Notes of this series 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
reasonable indemnity, and the Trustee shall not have received from the Holders of a majority in aggregate principal amount of such 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 Note for the enforcement of any payment of principal hereof or any premium or interest
hereon on or after the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this
Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this 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 Note is
registrable in the Security Register, upon surrender of this Note for registration of transfer at the office or agency of the Company in any place where the principal of and any premium and interest on this 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 Notes of this series 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 of this series 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, Notes of this series are exchangeable for a like principal amount of Notes of this series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 

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
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 Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 This Note is a Global Security and
is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 305 thereof on transfers and exchanges of Global Securities.
