ARTICLE TWO

TERMS AND ISSUANCE OF THE SENIOR NOTES

Section 2.1. Issue of Senior Notes. A series of Securities which shall be designated the “5.350% Senior Notes due 2028” shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to the terms, conditions and covenants of, the Original Indenture and this Fifteenth Supplemental Indenture (including the form of such Senior Notes set forth hereto as Exhibit A). The aggregate principal amount of Senior Notes which may be authenticated and delivered under this Fifteenth Supplemental Indenture shall not, except as permitted by the provisions of the Original Indenture, initially exceed $1,000,000,000; provided that the Company may from time to time or at any time, without the consent of the Holders of the Senior Notes, issue additional senior notes of the same or a different series in an unlimited aggregate principal amount; provided that if any such additional senior notes are not fungible with the Senior Notes (or any other tranche of additional senior notes) for U.S. federal income tax purposes, then such additional senior notes will have different CUSIP numbers than the Senior Notes (or any such other tranche of additional senior notes).

Section 2.2. Interest Rate Adjustment.

(a) The interest rate payable on the Senior Notes will be subject to adjustment from time to time if either Moody’s or S&P, or, in either case, any Substitute Rating Agency downgrades (or subsequently upgrades) the credit rating assigned to the Senior Notes, in the manner described below.

-9-

(b) If the rating from Moody’s (or any Substitute Rating Agency) of the Senior Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Senior Notes will increase such that it will equal the interest rate payable on the Senior Notes on the Issue Date plus the percentage set forth opposite the ratings from the table below:


Moody’s 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.

(c) If the rating from S&P (or any Substitute Rating Agency) of the Senior Notes is decreased to a rating set forth in the immediately following table, the interest rate on the Senior Notes will increase such that it will equal the interest rate payable on the Senior Notes on the Issue Date plus the percentage set forth opposite the ratings from the table below:


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.

(d) If at any time the interest rate on the Senior Notes has been adjusted upward and either Moody’s or S&P (or, in either case, a Substitute Rating Agency), as the case may be, subsequently increases its rating of the Senior Notes to any of the threshold ratings set forth above, the interest rate on the Senior Notes shall be decreased such that the interest rate for the Senior Notes shall equal the interest rate payable on the Senior Notes on the Issue Date plus the percentages set forth opposite the ratings from the tables in Sections 2.2(b) and (c) in effect immediately following the increase in rating. If Moody’s (or any Substitute Rating Agency) subsequently increases its rating of the Senior Notes to Baa3 (or its equivalent, in the case of a Substitute Rating Agency) or higher, and S&P (or any Substitute Rating Agency) increases its rating to BBB- (or its equivalent, in the case of a Substitute Rating Agency) or higher, the interest rate on the Senior Notes will be decreased to the interest rate payable on the Senior Notes on the Issue Date. In addition, the interest rate on the Senior Notes will permanently cease to be subject to any adjustment described above notwithstanding any subsequent decrease in the ratings by either or both Rating Agencies (or any Substitute Rating Agency therof) if the Senior Notes become rated Baa1 and BBB+ (or the equivalent of either such rating, in the case of a Substitute Rating Agency) or higher by each of Moody’s and S&P (or, in either case, a Substitute Rating Agency thereof), respectively (or by one Rating Agency in the event the Senior Notes are only rated by one Rating Agency and the Company has not obtained ratings from a Substitute Rating Agency).

-10-

(e) Each adjustment required by any decrease or increase 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), shall be made independent of any and all other adjustments, provided, however, that in no event shall (1) the interest rate for the Senior Notes be reduced to below the interest rate payable on the Senior Notes on the Issue Date or (2) the total increase in the interest rate on the Senior Notes exceed 2.00% above the interest rate payable on the Senior Notes on the Issue Date.

(f) No adjustments in the interest rate of the Senior Notes shall be made solely as a result of a Rating Agency ceasing to provide a rating of the Senior Notes. If at any time Moody’s or S&P ceases to provide a rating of the Senior Notes for any reason, the Company will use its commercially reasonable efforts to obtain a rating of the Senior Notes from a Substitute Rating Agency, to the extent one exists, and if a Substitute Rating Agency exists, for purposes of determining any increase or decrease in the interest rate on the Senior 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 Senior 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 the Company 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 Senior Notes will increase or decrease, as the case may be, such that the interest rate equals the interest rate payable on the Senior Notes on the Issue Date plus the appropriate percentage, if any, set forth opposite the 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 of Moody’s or S&P provides a rating of the Senior Notes and no Substitute Rating Agency is offered to replace the other Rating Agency, any subsequent increase or decrease in the interest rate of the Senior Notes necessitated by a reduction or increase in the rating by the agency providing the rating shall be twice the percentage set forth in the applicable table above. For so long as none of Moody’s, S&P or a Substitute Rating Agency provides a rating of the Senior Notes, the interest rate on the Senior Notes will increase to, or remain at, as the case may be, 2.00% above the interest rate payable on the Senior Notes on the Issue Date.

(g) Any interest rate increase or decrease described in this Section 2.2 will take effect on the next Business Day after the day on which the rating change has occurred.

(h) If the interest rate payable on the Senior Notes is increased as described above, the term “interest,” as used with respect to the Senior Notes, will be deemed to include any such additional interest unless the context otherwise requires.

(i) The Company shall promptly notify the Paying Agent on becoming aware of any decrease in the rating assigned to the Senior Notes by either Moody’s or S&P (or any Substitute Rating Agency). The Trustee shall not be responsible for and makes no representation as to any act or omission of any Rating Agency or any rating with respect to the Senior Notes or the selection of a Substitute Rating agency. The Trustee shall have no obligation to independently determine or verify if an event has occurred or notify the holders of any event dependent upon the rating of the Senior Notes, or if the rating on the Senior Notes has been changed, suspended or withdrawn by any Rating Agency.

Any endorsement of a Global Security to reflect the amount of any increase or decrease in the aggregate principal amount of Outstanding Senior Notes represented thereby shall be made by the Transfer Agent in accordance with instructions given by the Holder thereof as required by Section 2.9 hereof.

Prior to such registration of transfer or exchange, the requesting Holder shall present or surrender to the Transfer Agent the Definitive Securities duly endorsed or accompanied by a written instruction of transfer in form satisfactory to the Registrar duly executed by such Holder or by its attorney, duly authorized in writing. The Authenticating Agent shall cancel any such Definitive Securities so surrendered, and the Company shall execute and, upon receipt of a Company Order pursuant to Section 2.01 of the Original Indenture, the Authenticating Agent shall authenticate and deliver to the Person designated in the instructions a new Definitive Security in the appropriate principal amount.

At any time prior to such cancellation, if any beneficial interest in a Global Security is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security or for Definitive Securities, the principal amount of Securities represented by such Global Security shall be reduced accordingly and an endorsement shall be made on such Global Security by the Registrar or by the Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Security, such other Global Security shall be increased accordingly and an endorsement shall be made on such Global Security by the Registrar or by the Depositary at the direction of the Registrar to reflect such increase.

COVENANTS

Section 3.1. Payments of Additional Amounts by a Foreign Successor Issuer.

(a) All payments made under or with respect to the Senior Notes by any Foreign Successor Issuer will be made free and clear of and without withholding or deduction for or on account of any present or future tax, duty, levy, impost, assessment or other governmental charge (including, without limitation, penalties, interest and other similar liabilities related thereto) of whatever nature (collectively, “Taxes”) imposed or levied by or on behalf of any jurisdiction in which such Foreign Successor Issuer is organized, resident or doing business for tax purposes or from or through which such Foreign Successor Issuer makes any payment on the Senior Notes, or, in each case, any department or political subdivision thereof (each, a “Relevant Taxing Jurisdiction”), unless such Foreign Successor Issuer or any other applicable withholding agent is required to withhold or deduct Taxes by law. For the avoidance of doubt a Relevant Taxing Jurisdiction shall not include the United States, any state thereof or the District of Columbia. If a Foreign Successor Issuer or any other applicable withholding agent is required by law to make any such withholding or deduction, the Foreign Successor Issuer, subject to the exceptions listed below, will pay such additional amounts (“Additional Amounts”) as may be necessary to ensure that the net amount received by each beneficial owner of the Senior Notes after such withholding

-16-

or deduction (including withholding or deduction attributable to Additional Amounts payable hereunder) will not be less than the amount the beneficial owner would have received if such Taxes had not been withheld or deducted (provided that if the applicable withholding agent is a Person other than a Foreign Successor Issuer, the Additional Amounts payable by the Foreign Successor Issuer under this Section 3.1 shall not exceed the Additional Amounts that would have been payable by the Foreign Successor Issuer under this Section 3.1 had the Foreign Successor Issuer been the applicable withholding agent (i.e., had the Foreign Successor Issuer made payments directly to the applicable beneficial owner of the Senior Notes)).

(b) A Foreign Successor Issuer will not, however, pay Additional Amounts to a Holder or beneficial owner of Senior Notes:

(i) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed, withheld or deducted but for the Holder’s or beneficial owner’s present or former connection with the Relevant Taxing Jurisdiction (other than any connection resulting from the acquisition, ownership, holding or disposition of Senior Notes, the receipt of payments thereunder and/or the exercise or enforcement of rights under any Senior Notes);

(ii) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed, withheld or deducted but for the failure of the Holder or beneficial owner of Senior Notes following the Foreign Successor Issuer’s written request addressed to the Holder or beneficial owner, to the extent such Holder or beneficial owner is legally eligible to do so, either to provide information concerning the holder’s or beneficial owner’s nationality, residence or identity or to comply with any certification, identification, information or other reporting requirements, whether required by statute, treaty, regulation or administrative practice of a Relevant Taxing Jurisdiction, as a precondition to exemption from, or reduction in the rate of deduction or withholding of, Taxes imposed by the Relevant Taxing Jurisdiction (including, without limitation, a certification that the Holder or beneficial owner is not resident in the Relevant Taxing Jurisdiction);

(iii) with respect to any estate, inheritance, gift, sales, transfer, personal property, wealth or any similar Taxes;

(iv) if such Holder is a fiduciary or partnership or Person other than the sole beneficial owner of such payment and the Taxes giving rise to such Additional Amounts would not have been imposed on such payment had the Holder been the beneficiary, partner or sole beneficial owner, as the case may be, of such Senior Note (but only if there is no material cost or expense associated with transferring such Senior Note to such beneficiary, partner or sole beneficial owner and no restriction on such transfer that is outside the control of such beneficiary, partner or sole beneficial owner);

-17-

(v) to the extent the Taxes giving rise to such Additional Amounts would not have been imposed, withheld or deducted but for the presentation by the Holder or beneficial owner of any Senior Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for, whichever occurs later;

(vi) with respect to any Taxes imposed, withheld, levied or deducted pursuant to current Sections 1471 through 1474 of the Internal Revenue Code of 1986, as amended (the “Code”) (or any amended or successor version that is substantively comparable and not materially more onerous to comply with), any current or future regulations promulgated thereunder or official interpretations thereof, any agreement entered into pursuant to current Section 1471(b) of the Code (or any amended or successor version as described above) or any related fiscal or regulatory legislation, rules or official administrative practice adopted pursuant to any intergovernmental agreement entered into in connection with implementing any of the foregoing; or

(vii) any combination of items (i), (ii), (iii), (iv), (v) and (vi).

(c) A Foreign Successor Issuer will (i) make any such withholding or deduction required by applicable law and (ii) remit the full amount deducted or withheld to the relevant authority in accordance with applicable law. The Foreign Successor Issuer will make reasonable efforts to obtain certified copies of tax receipts evidencing the payment of any Taxes so deducted or withheld from each Relevant Taxing Jurisdiction imposing such Taxes and the Foreign Successor Issuer will provide to the Trustee, within a reasonable time after the date the payment of any Taxes so deducted or withheld are due pursuant to applicable law, either a certified copy of tax receipts evidencing such payment, or, if such tax receipts are not reasonably available to the Foreign Successor Issuer, such other documentation that provides reasonable evidence of such payment by the Foreign Successor Issuer.

(d) At least 30 calendar days prior to each date on which any payment under or with respect to the Senior Notes is due and payable, if the Foreign Successor Issuer will be obligated to pay Additional Amounts with respect to such payment (unless such obligation to pay Additional Amounts arises after the 35th day prior to the date on which payment under or with respect to the Senior Notes is due and payable, in which case it will be promptly thereafter), the Foreign Successor Issuer will deliver to the Trustee an Officers’ Certificate stating that such Additional Amounts will be payable and the amounts so payable and will set forth such other information necessary to enable the Trustee to pay such Additional Amounts to Holders on the payment date. The Foreign Successor Issuer will promptly publish a notice in accordance with Section 16.04 of the Original Indenture stating that such Additional Amounts will be payable and describing the obligation to pay such amounts.

-18-

(e) In addition, a Foreign Successor Issuer will pay any stamp, issue, registration, court, documentation, excise or other similar taxes, charges and duties, including interest, penalties and other similar liabilities with respect thereto, imposed by any Relevant Taxing Jurisdiction at any time after the merger described above in respect of the execution, issuance, registration or delivery of the Senior Notes or any other document or instrument referred to thereunder and any such taxes, charges or duties imposed by any Relevant Taxing Jurisdiction at any time after the merger described above as a result of, or in connection with, any payments made pursuant to the Senior Notes and/or the enforcement of the Senior Notes and/or any other such document or instrument.

(f) The obligations described under this heading will survive any termination, defeasance or discharge of the Indenture and will apply mutatis mutandis to any successor Person to any Foreign Successor Issuer (other than a Person organized under the laws of the United States, any state thereof or the District of Columbia) and to any jurisdiction in which such successor Person is organized, resident or doing business for tax purposes or any jurisdiction from or through which payment is made by such successor or its respective agents or, in each case, any department or political subdivision thereof.

(g) Whenever this Indenture or the Senior Notes refer to, in any context, the payment of principal, premium, if any, interest or any other amount payable under or with respect to any Senior Note, such reference includes the payment of Additional Amounts as described hereunder, if applicable.

Section 3.2. Limitations on Liens.

(a) The Company shall not (nor shall it permit any of its Significant Subsidiaries to) create or permit to exist any Lien on any Principal Property of the Company or any of its Significant Subsidiaries (or on any stock of a Significant Subsidiary), whether owned on the Issue Date or thereafter acquired, to secure any Indebtedness (any such Lien, a “Subject Lien”), unless the Company contemporaneously secures the Senior Notes (together with, if the Company so determines, any other Indebtedness of or guaranty by the Company or such Significant Subsidiary then existing or thereafter created that is not subordinated to the Senior Notes) equally and ratably with (or, at the option of the Company, prior to) that obligation.

(b) The foregoing restriction, however, shall not apply to (i) Permitted Liens and (ii) Liens securing Indebtedness if at the time of determination, after giving effect to the incurrence of such Indebtedness and to the retirement of Indebtedness which is being retired substantially concurrently therewith, the sum of (1) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Subject Liens (other than Permitted Liens) and (2) the Attributable Debt in respect of all Sale and Lease-Back Transactions not otherwise permitted under the first sentence of Section 3.3 hereof does not exceed fifteen percent of Consolidated Net Tangible Assets.

-19-

Section 3.3. Limitations on Sale and Lease-Back Transactions. The Company shall not, and shall not permit any of its Significant Subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property, other than (x) any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or (y) any such Sale and Lease-Back Transaction between the Company and one of its Subsidiaries or between its Subsidiaries, unless:

(a) the Company or such Significant Subsidiary would be entitled to incur Indebtedness secured by a Lien on the Principal Property involved in such Sale and Lease-Back Transaction at least equal in amount to the Attributable Debt with respect to such Sale and Lease-Back Transaction, without equally and ratably securing the Senior Notes, pursuant to Section 3.2 hereof; or

(b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of the affected Principal Property (as determined in good faith by the Board of Directors) and the Company applies an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back Transaction to any (or a combination) of:

(i) the prepayment or retirement of the Senior Notes;

(ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at Maturity) of other Indebtedness of the Company or of one of its Subsidiaries (other than Indebtedness that is subordinated to the Senior Notes or Indebtedness owed to the Company or one of its Subsidiaries) that matures more than 12 months after its creation (including any such Indebtedness that by its terms is renewable or extendible beyond 12 months from the date of its creation, at the option of the Company); or

(iii) the purchase, construction, development, expansion or improvement of other comparable property.

Notwithstanding the foregoing, the Company and its Significant Subsidiaries shall be allowed to enter into any Sale and Lease-Back Transaction if, after giving effect to such Sale and Lease-Back Transaction, the sum of (i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Subject Liens (other than Permitted Liens) and (ii) the Attributable Debt in respect of all Sale and Lease-Back Transactions not otherwise permitted under the first sentence of this Section 3.3, does not exceed fifteen percent of Consolidated Net Tangible Assets.

Section 3.4. Limitations on Mergers and Other Transactions. With respect to the Senior Notes, the provisions of Section 6.04 of the Original Indenture shall be replaced in its entirety with the following:

“Section 6.04. Company May Consolidate, Etc., Only on Certain Terms.

-20-

(a) The Company shall not consolidate or merge with another entity or sell, transfer or otherwise convey all or substantially all of its assets to another entity, unless in each case:

(1) the resulting entity (if other than the Company) (x) is a Person organized under the laws of any U.S. jurisdiction, the United Kingdom or any country that is a member country of the European Union on the Issue Date and (y) delivers a supplemental indenture by which such surviving entity expressly assumes the Company’s obligations under the Indenture; and

(2) immediately following the consolidation, merger, sale or conveyance, no Event of Default (as defined below) (and no event which, after notice or lapse of time or both, would become an Event of Default) shall have occurred and be continuing.

(b) Upon any consolidation of the Company with, or merger of the Company into, any other Person or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety to another Person in accordance with Section 6.04(a) hereof, the successor Person formed by such consolidation or into which the Company is merged or to which such merger, sale or conveyance, is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities.”

Section 3.5. Repurchase upon Change of Control Triggering Event.

(a) If a Change of Control Triggering Event occurs with respect to the Senior Notes, unless the Company has exercised its right pursuant to Section 4.1, Section 4.2 or Section 4.4 hereof to redeem the Senior Notes, the Company will make an offer to each Holder of the Senior Notes to repurchase all or, at such Holder’s option, any part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of such Holder’s Senior Notes (the “Change of Control Offer”) for payment in cash equal to 101% of the aggregate principal amount of the Senior Notes repurchased plus accrued and unpaid interest, if any, on the Senior Notes repurchased to, but not including, the date of purchase (the “Change of Control Payment”).

(b) Within 30 days following any Change of Control Triggering Event with respect to the Senior Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the transaction or transactions that constitute or may constitute a Change of Control, the Company will mail a notice to Holders of the Senior Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Triggering Event and offering to repurchase such Senior Notes on the date specified in the notice, which date will be no earlier than 30 and no later than 60 days from the date such notice is mailed (the “Change of Control Payment Date”), pursuant to the procedures required

-21-

by such Senior Notes and described in such notice. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. Upon ten (10) Business Days’ advance written notice to the Trustee, the Company may request the Trustee to send the notice to Holders described in this Section 3.5(b) in the name of and at the expense of the Company.

(c) The Company will comply with the requirements 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 such Senior 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 Senior Notes or the Indenture, the Company will comply with those securities laws and regulations and will not be deemed to have breached its obligations under the Senior Notes or the Indenture by virtue of such conflict.

(d) On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all Senior Notes or portions of Senior Notes properly tendered pursuant to the Change of Control Offer;

(ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Senior Notes or portions of Senior Notes properly tendered; and

(iii) deliver or cause to be delivered to the Trustee or the Paying Agent properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Senior Notes or portions of Senior Notes being purchased by the Company.

(e) The Paying Agent shall promptly mail, to each Holder who properly tendered Senior Notes, the purchase price for such Senior Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Security equal in principal amount to any unpurchased portion of the Senior Notes surrendered, if any; provided that each new Security will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

(f) The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes such a Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Fifteenth Supplemental Indenture applicable to a Change of Control Offer made by the Company and such third party purchases all Senior Notes properly tendered and not withdrawn under its Change of Control Offer. In the event that such third party terminates or defaults on its Change of Control Offer, the Company shall make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

-22-

(g) The Company will not purchase any Senior Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment.

ARTICLE FOUR

Section 4.1. Optional Redemption by Company.

(a) Prior to May 28, 2028 (one (1) month before the maturity date of the Senior Notes) (the “Par Call Date”), the Company shall have the right to redeem the Senior Notes, in whole, at any time, or in part, from time to time, at the option of the Company, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) (the “Make-Whole Redemption Price”) equal to the greater of:

(i) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Senior Notes matured on the Par Call 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 less (b) interest accrued to the Redemption Date, and

(ii) 100% of the principal amount of the Senior Notes to be redeemed; and

plus, in either case, accrued and unpaid interest thereon to the Redemption Date.

If the Redemption Date is after a Record Date and on or prior to a corresponding Interest Payment Date, interest will be paid on the Redemption Date to the holder of record on the Record Date. On and after a Redemption Date, interest will cease to accrue on the Senior Notes called for redemption (unless the Company defaults in the payment of the Make-Whole Redemption Price and accrued interest). On or before a Redemption Date, the Company will deposit with the Paying Agent (or the Trustee) money sufficient to pay the Make-Whole Redemption Price of and accrued interest on the Senior Notes to be redeemed on that date.

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two paragraphs:

The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining

-23-

Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – interpolated to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date.

If on the third Business Day preceding the Redemption Date H.15 or any successor designation or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places.

The Company’s actions and determinations in determining the Make Whole Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(b) Notwithstanding the foregoing, at any time on or after the Par Call Date, the Company shall have the right to redeem the Senior Notes in whole at any time or in part, from time to time, at its option, at a redemption price equal to 100% of the principal amount of the Senior Notes to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date.

-24-

(c) Notice of any redemption pursuant to this Section 4.1 shall be given as provided in Section 4.03 of the Original Indenture, with a copy to the Paying Agent; provided, that, with respect to the Senior Notes, (i) the number “30” referenced in Section 4.03(a) of the Original Indenture shall be replaced with the number “10” and (ii) the phrase “; provided, that any notice of redemption delivered pursuant to Section 4.03(a) may be electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures)” shall be added before the period in Section 16.04(a) of the Original Indenture. Any notice of redemption will be given prior to the applicable Redemption Date and any such notice of redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion of securities offerings or other corporate transactions. If the Company requests the Trustee to provide such notice of redemption pursuant to Section 4.03 of the Original Indenture, the Trustee shall receive written notice from the Company at least 10 days prior to when such notice of redemption is to be delivered (unless a shorter period is agreed by the Trustee). The Trustee shall not be responsible for the calculation of such Make-Whole Redemption Price. The Company shall calculate such Make-Whole Redemption Price and promptly notify the Trustee in writing thereof.

(d) If the Company elects to redeem less than all of the Senior Notes, and such Senior Notes are at the time represented by a global note, then the Trustee will select pro rata or by lot or by a method the Trustee deems to be fair and appropriate, in accordance with the depositary’s procedures, the particular interests to be redeemed. If the Company elects to redeem less than all of the Senior Notes, and any of such Senior Notes are not represented by a global note, then the Trustee will select the particular Senior Notes to be redeemed in a manner it deems appropriate and fair (and the depositary will select by lot the particular interests in any global note to be redeemed). No Senior Notes of a principal amount of $2,000 or less will be redeemed in part. If any Senior Note is to be redeemed in part only, the notice of redemption that relates to the Senior Note will state the portion of the principal amount of the Senior Note to be redeemed.

Section 4.2. Tax Redemption.

If, as a result of:

(i) any amendment to, or change in, the laws (or regulations or rulings promulgated thereunder) or treaties of any Relevant Taxing Jurisdiction which is announced and becomes effective after the date on which a Foreign Successor Issuer becomes a Foreign Successor Issuer (or, where a jurisdiction in question does not become a Relevant Taxing Jurisdiction until a later date, such later date); or

(ii) any amendment to, or change in, the official application or official interpretation of the laws, regulations or rulings of any Relevant Taxing Jurisdiction (including any such amendment or change resulting from a holding by a court of competent jurisdiction in the Relevant Taxing Jurisdiction) which is announced and becomes effective after the date on which a Foreign Successor Issuer becomes a Foreign Successor Issuer (or, where a jurisdiction in question does not become a Relevant Taxing Jurisdiction until a later date, such later date),

-25-

such Foreign Successor Issuer would be obligated to pay, on the next date for any payment, Additional Amounts pursuant to Section 3.1 hereof with respect to the Relevant Taxing Jurisdiction, which such Foreign Successor Issuer reasonably determines it cannot avoid by the use of reasonable measures available to it, then such Foreign Successor Issuer may redeem all, but not less than all, of the Senior Notes, at any time thereafter, upon not less than 30 nor more than 60 days’ notice, at a redemption price of 100% of their principal amount, plus accrued and unpaid interest, if any, to the Redemption Date. Prior to the giving of any notice of redemption described in this paragraph, a Foreign Successor Issuer will deliver to the Trustee:

(i) a certificate signed by an officer of such Foreign Successor Issuer stating that the obligation to pay the Additional Amounts cannot be avoided by such Foreign Successor Issuer’s taking reasonable measures available to it; and

(ii) a written opinion of independent legal counsel to such Foreign Successor Issuer of recognized standing to the effect that such Foreign Successor Issuer has or will become obligated to pay such Additional Amounts as a result of a change, amendment, official interpretation or application described above.

Section 4.3. Notice of Redemption. A Foreign Successor Issuer will deliver a notice of any optional redemption of the Senior Notes described above to each registered holder of the Senior Notes in accordance with Section 4.03 of the Original Indenture. No such notice of redemption may be given more than 60 days before or 365 days after the Foreign Successor Issuer first becomes liable to pay any Additional Amounts. If the Foreign Successor Issuer requests the Trustee to provide the notice in accordance with Section 4.03 of the Original Indenture, the Trustee shall receive written notice from the Company at least 10 days prior to when such notice of redemption is to be delivered (unless a shorter period is agreed by the Trustee).

The Trustee will then promptly deliver such notice to each holder of Senior Notes at its registered address. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after such Special Mandatory Redemption Date, interest will cease to accrue on the Senior Notes and the Indenture will be discharged and cease to be of further effect as to all Senior Notes.

This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $1,000,000,000, provided that the Company may, without the consent of any Holder, at any time and from time to time increase the initial principal amount.

The Securities of this series are subject to redemption as provided in Sections 4.1, 4.2, 4.3 and 4.4 of the Fifteenth Supplemental Indenture.

The Indenture contains provisions for defeasance at any time of the entire indebtedness of this Security and certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to the Securities of this series shall occur and be continuing, the unpaid 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 (i) permitting the Holders of not less than a majority in principal amount of the Securities of any series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture with respect to such series and (ii) permitting the Holders of a majority in principal amount of the Securities at the time Outstanding of any series to be affected under the Indenture (with each such series considered separately for this purpose), 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 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 notation of such consent or waiver is made upon this Security.

A-5

As provided in and subject to the provisions of the Indenture, the Holder of this Security 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 Securities of this series, the Holders of not less than 25% in principal amount of the Securities 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 indemnity reasonably satisfactory, 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 Security 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 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 any premium and interest on this Security 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 Security is registrable in the Register, upon surrender of this Security for registration of transfer at the Registrar, 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 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 Securities of this series are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. A Holder who, as a result of trading or otherwise, holds a principal amount of the Securities that is less than the minimum denomination of the Securities is required to purchase an additional principal amount of the Securities such that its holdings of the Securities amounts to the minimum specified denomination. As provided in the Indenture and subject to certain limitations therein set forth, the Securities of this series are exchangeable for a like aggregate principal amount of the Securities of this series 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 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 be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

This Security is a Global Security and is subject to the provisions of the Indenture relating to Global Securities, including the limitations in Section 3.06 of the Original Indenture and Section 2.8 of the Fifteenth Supplemental Indenture on transfers and exchanges of Global Securities.

Interest on the principal balance of the Securities of this series shall be calculated on the basis of a 360-day year of twelve 30-day months.

If any Interest Payment Date, Redemption Date or Maturity falls on a day that is not a Business Day, then the relevant payment may be made on the next succeeding Business Day and no interest will accrue because of such delayed payment.

THE SECURITIES OF THIS SERIES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

All capitalized terms used but not defined in this Security shall have the meanings assigned to them in the Indenture.
