WHEREAS, the Company has heretofore entered into a Senior Note Indenture, dated as of January 1, 2007 (the “Original Indenture”), with the Trustee, as heretofore supplemented;

WHEREAS, the Original Indenture is incorporated herein by this reference and the Original Indenture, as heretofore supplemented and as further supplemented by this Third Supplemental Indenture, is herein called the “Indenture”;

WHEREAS, under the Original Indenture, a new series of Senior Notes may at any time be established pursuant to a supplemental indenture executed by the Company and the Trustee;

WHEREAS, the Company proposes to create under the Indenture a new series of Senior Notes;

WHEREAS, additional Senior Notes of other series hereafter established, except as may be limited in the Original Indenture as at the time supplemented and modified, may be issued from time to time pursuant to the Indenture as at the time supplemented and modified; and

WHEREAS, all conditions necessary to authorize the execution and delivery of this Third Supplemental Indenture and to make it a valid and binding obligation of the Company have been done or performed.

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

SECTION 101. Establishment. There is hereby established a new series of Senior Notes to be issued under the Indenture, to be designated as the Company’s Series 2008A Floating Rate Senior Notes due August 20, 2010 (the “Series 2008A Notes”).

There are to be authenticated and delivered $600,000,000 principal amount of Series 2008A Notes, and such principal amount of the Series 2008A Notes may be increased from time to time

pursuant to Section 301 of the Original Indenture. All Series 2008A Notes need not be issued at the same time and such series may be reopened at any time, without the consent of any Holder, for issuances of additional Series 2008A Notes. Any such additional Series 2008A Notes will have the same interest rate, maturity and other terms as those initially issued. No Series 2008A Notes shall be authenticated and delivered in excess of the principal amount as so increased except as provided by Sections 203, 303, 304 or 907 of the Original Indenture. The Series 2008A Notes shall be issued in definitive fully registered form.

The Series 2008A Notes shall be issued in the form of one or more Global Securities in substantially the form set out in Exhibit A hereto. The Depositary with respect to the Series 2008A Notes shall be The Depository Trust Company.

The form of the Trustee’s Certificate of Authentication for the Series 2008A Notes shall be in substantially the form set forth in Exhibit B hereto.

Each Series 2008A Note shall be dated the date of authentication thereof and shall bear interest from the date of original issuance thereof or from the most recent Interest Payment Date to which interest has been paid or duly provided for.

The Series 2008A Notes will not be redeemable at the option of the Company prior to the Stated Maturity and will not have a sinking fund.

SECTION 102. Definitions. The following defined terms used herein shall, unless the context otherwise requires, have the meanings specified below. Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Original Indenture.

“Calculation Agent” means Wells Fargo Bank, National Association, or its successor appointed by the Company, acting as calculation agent for the Series 2008A Senior Notes.

“Interest Determination Date” means the second London Business Day immediately preceding the first day of the relevant Interest Period.

“Interest Payment Dates” means the 20th day of February, May, August and November, commencing November 20, 2008; provided, however, in the event that any Interest Payment Date (other than the Interest Payment Date that is the Stated Maturity) would otherwise be a day that is not a Business Day, the Interest Payment Date will be the next succeeding Business Day.

“Interest Period” means the period commencing on an Interest Payment Date (or, with respect to the initial Interest Period only, commencing on the Original Issue Date) and ending on the day before the next succeeding Interest Payment Date.

Interest Period. If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period, LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars for the Interest Period and in a principal amount of not less than $1,000,000 are offered to prime banks in the London interbank market by four major banks in the London interbank market (which may include affiliates of one or more of the underwriters of the Series 2008A Notes) selected by the Calculation Agent (after consultation with the Company), at approximately 11:00 a.m., London time on the Interest Determination Date for that Interest Period. The Calculation Agent will request the principal London office of each such bank to provide a quotation of its rate. If at least two such quotations are provided, LIBOR with respect to that Interest Period will be the arithmetic mean of such quotations. If fewer than two quotations are provided, LIBOR with respect to that Interest Period will be the arithmetic mean of the rates quoted by three major banks in New York City (which may include affiliates of one or more of the underwriters of the Series 2008A Notes) selected by the Calculation Agent (after consultation with the Company), at approximately 11:00 a.m., New York City time, on the first day of that Interest Period for loans in U.S. dollars to leading European banks for that Interest Period and in a principal amount of not less than $1,000,000. However, if fewer than three banks selected by the Calculation Agent to provide quotations are quoting as described above, LIBOR for that Interest Period will be the same as LIBOR as determined for the previous Interest Period.

“London Business Day” means a day that is a Business Day and a day on which dealings in deposits in U. S. dollars are transacted, or with respect to any future date are expected to be transacted, in the London interbank market.

“Regular Record Date” means, with respect to each Interest Payment Date, the close of business on the 15th calendar day preceding such Interest Payment Date, whether or not a Business Day.

“Reuters LIBOR01 Page” means the display designated as Reuters LIBOR01 on the Reuters 3000 Xtra (or such other page as may replace the Reuters LIBOR01 Page on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying rates or prices comparable to the London Interbank Offered rate for U.S. dollar deposits).

“Stated Maturity” means August 20, 2010; provided that if the Stated Maturity is not a Business Day, the principal and interest due on that date will be payable on the next succeeding Business Day, and no interest shall accrue for the intervening period.

SECTION 103. Payment of Principal and Interest. The principal of the Series 2008A Notes shall be due at Stated Maturity. The unpaid principal amount of the Series 2008A Notes shall bear interest at the rates set quarterly pursuant to Section 104 hereof until paid or duly provided for. Interest shall be paid quarterly in arrears on each Interest Payment Date to the Person in whose name the Series 2008A Notes are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity of principal as provided herein

will be paid to the Person to whom principal is payable. Any such interest that is not so punctually paid 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 2008A 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, notice whereof shall be given to Holders of the Series 2008A Notes not less than ten (10) days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange, if any, on which the Series 2008A Notes shall be listed, and upon such notice as may be required by any such exchange, all as more fully provided in the Original Indenture.

Payments of interest on the Series 2008A Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Series 2008A Notes shall be computed and paid on the basis of the actual number of days elapsed over a 360-day year.

Payment of the principal and interest due at the Stated Maturity of the Series 2008A Notes shall be made upon surrender of the Series 2008A Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Series 2008A Notes shall be paid in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. Payments of 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 or other electronic transfer at such place and to such account at a banking institution in the United States as may be designated in writing to the Trustee at least sixteen (16) days prior to the date for payment by the Person entitled thereto.

SECTION 104. Determination of Interest. The Series 2008A Notes will bear interest for each Interest Period at a per annum rate determined by the Calculation Agent, subject to the maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application. The interest rate applicable during each Interest Period will be equal to LIBOR on the Interest Determination Date for such Interest Period plus 0.70%. Promptly upon such determination, the Calculation Agent will notify the Company and the Trustee, if the Trustee is not then serving as the Calculation Agent, of the interest rate for the new Interest Period. The interest rate determined by the Calculation Agent, absent manifest error, shall be binding and conclusive upon the beneficial owners and Holders of the Series 2008A Notes, the Company and the Trustee.

Upon the request of a Holder of the Series 2008A Notes, the Calculation Agent will provide to such Holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Period.

Accrued interest on a Series 2008A Note for any period shall be calculated by multiplying the principal amount of such Series 2008A Note by an accrued interest factor. The accrued interest factor shall be computed by adding the interest factor calculated for each day in the period for which accrued interest is being calculated. The interest factor (expressed as a decimal

rounded upwards if necessary) shall be computed by dividing the interest rate (expressed as a decimal rounded upwards if necessary) applicable to such date by 360.

All percentages resulting from any calculation of the interest rate on the Series 2008A Notes shall be rounded, if necessary, to the nearest one-hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards, and all dollar amounts used in or resulting from such calculation shall be rounded to the nearest cent (with one-half cent being rounded upwards).

SECTION 105. Denominations. The Series 2008A Notes may be issued in the denominations of $1,000, or any integral multiple thereof.

SECTION 106. Global Securities. The Series 2008A Notes will be 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 2008A Notes represented by one or more Global Securities will not be exchangeable for, and will not otherwise be issuable as, Series 2008A Notes in definitive form. 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 2008A 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. The rights of Holders of such Global Security shall be exercised only through the Depositary.

Subject to the procedures of the Depositary, a Global Security shall be exchangeable for Series 2008A 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, or if at any time the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, 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, in each case within 90 days after the Company receives such notice or becomes aware of such cessation, (ii) the Company in its sole discretion determines that such Global Security shall be so exchangeable, or (iii) there shall have occurred an Event of Default with respect to the Series 2008A Notes. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Series 2008A Notes registered in such names as the Depositary shall direct.

SECTION 107 Transfer. No service charge will be made for any transfer or exchange of Series 2008A Notes, but payment will be required of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection therewith.

SECTION 201. Recitals by Company. The recitals in this Third Supplemental Indenture are made by the Company only and not by the Trustee, and all of the provisions contained in the Original Indenture in respect of the rights, privileges, immunities, powers and duties of the Trustee shall be applicable in respect of Series 2008A Notes and of this Third Supplemental Indenture as fully and with like effect as if set forth herein in full.

SECTION 202. Ratification and Incorporation of Original Indenture. As heretofore supplemented and as supplemented hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture as heretofore supplemented and as supplemented by this Third Supplemental Indenture shall be read, taken and construed as one and the same instrument.

SECTION 203. Executed in Counterparts. This Third Supplemental Indenture may be simultaneously executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument.

IN WITNESS WHEREOF, each party hereto has caused this instrument to be signed in its name and behalf by its duly authorized officers, all as of the day and year first above written.
