ARTICLE I

7.30% Senior Notes Due 2014

SECTION 1.01. Establishment.

There is hereby established a new series of senior notes to be issued under the Indenture, to be designated as the Company’s 7.30% Senior Notes due 2014 (the “Senior Notes”).

3

There are to be authenticated and delivered Senior Notes, initially limited in aggregate principal amount of $200,000,000 and no further Senior Notes shall be authenticated and delivered except as provided by Section 2.2, 2.4, 2.6, 2.8, 2.9, 2.11, 6.12, 8.5 or 12.3 of the Original Indenture; provided, however, that the aggregate principal amount of the Senior Notes may be increased in the future, without the consent of the holders of the Senior Notes, on the same terms and with the same CUSIP and ISIN numbers as the Senior Notes. The Senior Notes shall be issued in fully registered form.

The Senior Notes shall be issued in the form of one or more Global Securities (as defined below) in substantially the form set out in Exhibit A hereto. The Depositary with respect to the Senior Notes shall be The Depository Trust Company.

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

Each Senior 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.

SECTION 1.02. 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.

“Global Security” means, with respect to any series of securities, a security authenticated and delivered under the Original Indenture executed by the Company and delivered by the Trustee to the Depositary or pursuant to the Depositary’s instruction, all in accordance with the Original Indenture, which shall be registered in the name of the Depositary or its nominee.

“Interest Payment Date” means June 15 and December 15 of each year, commencing December 15, 2004.

“Original Issue Date” means June 29, 2004.

The principal of the Senior Notes shall be due at Stated Maturity. The unpaid principal amount of the Senior Notes shall bear interest at the rate of 7.30% per year until paid or duly provided for, such interest to accrue from June 29, 2004 or from the most

4

recent Interest Payment Date to which interest has been paid or duly provided for. Interest shall be paid semi-annually in arrears on each Interest Payment Date, commencing December 15, 2004, to the Person in whose name the Senior Notes are registered on the Regular Record Date for such Interest Payment Date, provided that interest payable at the Stated Maturity of principal or on a Redemption Date 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 be paid as provided in Section 2.7 of the Original Indenture.

Payments of interest on the Senior Notes will include interest accrued to but excluding the respective Interest Payment Dates. Interest payments for the Senior Notes shall be computed and paid on the basis of a 360-day year consisting of twelve 30-day months. In the event that any date on which interest is payable on the Senior Notes is not a Business Day, then payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if made on the date the payment was originally payable.

Payment of the principal, premium, if any, and interest due at the Stated Maturity of, or on a Redemption Date for, the Senior Notes shall be made upon surrender of the Senior Notes at the Corporate Trust Office of the Trustee. The principal of and interest on the Senior 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 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 15 days prior to the date for payment by the Person entitled thereto.

SECTION 1.04. Denominations.

The Senior Notes may be issued in denominations of $1,000, or whole multiples of $1,000 in excess of $2,000.

SECTION 1.05. Global Securities.

The Senior Notes will initially be issued in the form of one or more Global Securities registered in the name of the Depositary (which initially shall be The Depository Trust Company) or its nominee.

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

A Global Security shall be exchangeable for Senior Notes registered in the names of Persons other than the Depositary or its nominee only as provided by Section 2.8 (5) of the Original Indenture. Any Global Security that is exchangeable pursuant to the preceding sentence shall be exchangeable for Senior Notes registered in such names as the Depositary shall direct.

SECTION 1.06. Transfer.

No service charge will be made for any registration of transfer or exchange of Senior 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 1.07. Defeasance.

The provisions of Sections 10.4 and 10.5 of the Original Indenture will apply to the Senior Notes.

SECTION 1.08. Redemption at the Option of the Company.

The Senior Notes will be redeemable, at the option of the Company, in whole at any time or in part from time to time (a “Redemption Date”), at a redemption price (the “Redemption Price”) equal to the greater of (i) 100% of the principal amount of the Senior Notes to be redeemed and (ii) an amount equal to the sum of the present values of the remaining scheduled payments for principal and interest on the Senior Notes to be redeemed, not including any portion of the payments of interest accrued as of such Redemption Date, discounted to such Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 50 basis points; plus in each case, accrued and unpaid interest on the Senior Notes to be redeemed to, but excluding, such Redemption Date.

“Treasury Rate” means the rate per year equal to the semi-annual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the Redemption Date.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Senior Notes 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 the Senior Notes.

“Independent Investment Banker” means Goldman, Sachs & Co. and any successor firm or, if such firm is unwilling or unable to select the Comparable Treasury Issue, an independent investment banking institution of national standing appointed by the Trustee after consultation with the Company.

“Comparable Treasury Price” means with respect to any Redemption Date for the Senior Notes (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations.

“Reference Treasury Dealer” means each of Goldman, Sachs & Co. and four other primary U.S. government securities dealers (each a “Primary Treasury Dealer”), as specified by the Company; provided that (1) if any of Goldman, Sachs & Co. or any Primary Treasury Dealer as specified by the Company shall cease to be a Primary Treasury Dealer, the Company will substitute therefore another Primary Treasury Dealer and (2) if the Company fails to select a substitute within a reasonable period of time, then the substitute will be a Primary Treasury Dealer selected by the Trustee after consultation with the Company.

“Reference Treasury Dealer Quotations” means, with respect to the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed, in each case, as a percentage of its principal amount) quoted in writing to the Trustee by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

Notwithstanding Section 12.2 of the Original Indenture, the notice of redemption with respect to the foregoing redemption need not set forth the Redemption Price but only the manner of calculation thereof.

The Company shall notify the Trustee of the Redemption Price with respect to the foregoing redemption promptly after the calculation thereof. The Trustee shall not be responsible for calculating said Redemption Price.

If less than all of the Senior Notes are to be redeemed, The Depository Trust Company, as depositary, shall determine, in accordance with its procedures, the principal amount of such senior notes held by each beneficial owner of such notes to be redeemed. The Depository Trust Company may select notes and portions of notes in amounts of $1,000 and whole multiples of $1,000 in excess of $2,000.
