This Security is one of the series designated on the face hereof, limited in aggregate principal amount to U.S. $1,500,000,000, subject to (i) the Company’s right from time to time, without giving notice to or seeking the consent of the holders of the Securities, to issue an unlimited amount of additional securities in one or more series having the same ranking and the same interest rate, maturity and other terms as the Securities other than issue date, issue price and the payment of interest accruing prior to the issue date of the additional securities (such additional securities having such similar terms, together with the Securities of this series, constituting a single issue of Securities under the Indenture), provided that if such additional securities are not fungible with the then-outstanding Securities of this series for U.S. federal income tax purposes, the additional securities shall have a separate CUSIP number, and (ii) Securities of this series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this series pursuant to the provisions of the Indenture.

Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the relevant Interest Payment Date to the Holders of the Securities as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date. The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Partial redemption must be made in an amount not less than U.S. $2,000 or any integral multiple of U.S. $1,000 in excess thereof.

Morgan Securities LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States of America (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (b) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company 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, the rate per annum equal to the semiannual equivalent yield to maturity of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and any interest on such Security 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 Securities 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 Company and the Trustee shall be entitled to request an opinion of counsel providing that the transfer complies with applicable securities laws.

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.

This Security is one of the series designated on the face hereof, limited in aggregate principal amount to U.S. $2,000,000,000, subject to (i) the Company’s right from time to time, without giving notice to or seeking the consent of the holders of the Securities, to issue an unlimited amount of additional securities in one or more series having the same ranking and the same interest rate, maturity and other terms as the Securities other than issue date, issue price and the payment of interest accruing prior to the issue date of the additional securities (such additional securities having such similar terms, together with the Securities of this series, constituting a single issue of Securities under the Indenture), provided that if such additional securities are not fungible with the then-outstanding Securities of this series for U.S. federal income tax purposes, the additional securities shall have a separate CUSIP number, and (ii) Securities of this series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this series pursuant to the provisions of the Indenture.

As provided in the Indenture and subject to certain limitations therein set forth Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of any authorized denominations, as requested by the Holder surrendering the same, upon surrender of the Security or Securities to be exchanged at any office or agency described below where Securities of this series may be presented for registration of transfer.

Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the relevant Interest Payment Date to the Holders of the Securities as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date. The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Partial redemption must be made in an amount not less than U.S. $2,000 or any integral multiple of U.S. $1,000 in excess thereof.

Notice of redemption will be sent to Holders of Securities, not more than 60 days nor less than 10 days prior to the date fixed for redemption, all as provided in the Indenture.

“Reference Treasury Dealer” means (a) each of BofA Securities, Inc., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States of America (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (b) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company 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, the rate per annum equal to the semiannual equivalent yield to maturity of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

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 herefor or in lieu hereof, whether or not notification of such consent or waiver is made upon this Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice at the Corporate Trust Office of a continuing Event of Default with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series and all other affected series shall have made written request to the Trustee to institute such proceeding as trustee (and offered security or indemnity satisfactory to the Trustee), and the Trustee shall not have

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and any interest on such Security 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 Securities 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 Company and the Trustee shall be entitled to request an opinion of counsel providing that the transfer complies with applicable securities laws.

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 Security 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 Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

[Reverse of Security]

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 March 20, 2014 (as supplemented by the Officer’s Certificate setting forth the terms of the Securities dated as of the date hereof, herein called the “Indenture”), between the Company and Deutsche Bank Trust Company Americas, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made 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 Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited in aggregate principal amount to U.S. $2,750,000,000, subject to (i) the Company’s right from time to time, without giving notice to or seeking the consent of the holders of the Securities, to issue an unlimited amount of additional securities in one or more series having the same ranking and the same interest rate, maturity and other terms as the Securities other than issue date, issue price and the payment of interest accruing prior to the issue date of the additional securities (such additional securities having such similar terms, together with the Securities of this series, constituting a single issue of Securities under the Indenture), provided that if such additional securities are not fungible with the then-outstanding Securities of this series for U.S. federal income tax purposes, the additional securities shall have a separate CUSIP number, and (ii) Securities of this series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of this series pursuant to the provisions of the Indenture. The Securities of this series are issuable as Securities only in registered form, without coupons in denominations of U.S. $2,000 or any integral multiple of U.S. $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor of any authorized denominations, as requested by the Holder surrendering the same, upon surrender of the Security or Securities to be exchanged at any office or agency described below where Securities of this series may be presented for registration of transfer.

Any or all of the Securities of this series are redeemable at the Company’s option at any time. The redemption price for any Securities to be redeemed on any date fixed for redemption by or pursuant to the Indenture and the Securities (a “Redemption Date”) that is prior to September 19, 2049 (six months before Maturity of the Securities) will be equal to the greater of the following amounts:

plus, in each case, accrued and unpaid interest on the Securities to such Redemption Date.

The redemption price for any Securities to be redeemed on a Redemption Date that is on or after September 19, 2049 (six months before Maturity of the Securities) will be equal to 100% of the principal amount of the Securities being redeemed on such Redemption Date, plus accrued and unpaid interest on such Securities to such Redemption Date.

Notwithstanding the foregoing, installments of interest on the Securities that are due and payable on Interest Payment Dates falling on or prior to a Redemption Date will be payable on the relevant Interest Payment Date to the Holders of the Securities as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date. The redemption price will be calculated on the basis of a 360-day year consisting of twelve 30-day months.

Partial redemption must be made in an amount not less than U.S. $2,000 or any integral multiple of U.S. $1,000 in excess thereof.

Notice of redemption will be sent to Holders of Securities, not more than 60 days nor less than 10 days prior to the date fixed for redemption, all as provided in the Indenture.

E-5

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 cancellation hereof.

“Comparable Treasury Issue” means the United States Treasury security having a maturity comparable to the remaining term of the Securities 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.

“Comparable Treasury Price” means, with respect to any Redemption Date, (a) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (b) if the Company obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations, or (c) if only one Reference Treasury Dealer Quotation is received, such quotation.

“Reference Treasury Dealer” means (a) each of BofA Securities, Inc., Citigroup Global Markets Inc. and J.P. Morgan Securities LLC (or their respective affiliates which are Primary Treasury Dealers (as defined below)), and their respective successors; provided, however, that if any of the foregoing shall cease to be a primary U.S. Government securities dealer in the United States of America (a “Primary Treasury Dealer”), the Company will substitute therefor another Primary Treasury Dealer; and (b) any other Primary Treasury Dealer(s) selected by the Company.

“Reference Treasury Dealer Quotation” means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company 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, the rate per annum equal to the semiannual equivalent yield to maturity of the applicable Comparable Treasury Issue, assuming a price for such Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date.

Subject to certain conditions set forth in the Indenture, the Company at any time may discharge or defease some of or all of its obligations under this Security and the Indenture in accordance with Section 4.03 of the Indenture.

If an Event of Default with respect to 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 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 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 (with each series voting as a separate class in certain cases specified in the Indenture, or with all series voting as one class, in certain other cases specified in the Indenture), on behalf of the Holders of all Securities 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 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 herefor or in lieu hereof, whether or not notification of such consent or waiver is made upon this Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice at the Corporate Trust Office of a continuing Event of Default with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series and all other affected series shall have made written request to the Trustee to institute such proceeding as trustee (and offered security or indemnity satisfactory to the Trustee), and the Trustee shall not have

E-6

received from the Holders of a majority in principal amount of the Outstanding Securities of all affected series a direction inconsistent with such request and shall have failed to institute such proceedings within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of (and premium, if any) or any interest on this Security on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and any interest on this Security at the times, places 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 Security is registrable in the Security Register, upon surrender of this Security for registration of transfer at the office or agency of the Company in any place where the principal of (and premium, if any) and any interest on such Security 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 Securities 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 Company and the Trustee shall be entitled to request an opinion of counsel providing that the transfer complies with applicable securities laws.

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 Security 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 Security is overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

Notwithstanding anything in the Indenture or in the terms of this Security to the contrary, the exchange of this Security for a Security will be subject to satisfaction of the provisions of the United States tax laws in effect at the time of the exchange. Neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be required to exchange this Security for a Security if (a) as a result thereof and in the Company’s judgment, the Company would incur adverse consequences under then applicable United States Federal income tax laws and (b) in the case of the Trustee or any agent of the Company or the Trustee, the Company shall have delivered to such Person an Officer’s Certificate and an Opinion of Counsel as to the matters set forth in clause (a) above.

The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York.

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