7.75% SENIOR NOTES DUE 2016

This Note is one of a duly authorized issue of Securities of the Company issued under an Indenture, dated as of January 16, 2008 (the “ Indenture ”), between the Company and The Bank of New York Mellon Trust Company, N.A. (the “ Trustee ,” which term includes any successor trustee under the Indenture), designated as the 7.75% Senior Notes due 2016 (the “ Notes ”), limited to $312,000,000 aggregate principal amount, subject to the provisions of the Indenture. Reference is made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. All terms used in this Note set forth below which are not defined herein and which are defined in the Indenture shall have the meanings assigned to them in the Indenture.

The Indenture provides for the defeasance of the Notes and certain covenants in certain circumstances.

This Note is unsecured as to payment of principal and premium, if any, and interest, and ranks pari passu with all other unsecured senior indebtedness of the Company.

Interest payments on this Note will include interest accrued to but excluding the applicable Interest Payment Date or Maturity hereof, as the case may be. Interest payments for this Note shall be computed and paid on the basis of a 360-day year of twelve 30-day months.

In the case where the applicable Interest Payment Date or Maturity with respect hereto, as the case may be, does not fall on a Business Day, payment of principal, premium, if any, or interest otherwise payable on such day need not be made on such day, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date or at Maturity and, unless the Company defaults on such payment, no interest shall accrue with respect to such payment for the period from and after the Interest Payment Date or such Maturity, as the case may be, to the date of payment on such next succeeding Business Day. “Business Day” means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law, regulation or executive order to close in The City of New York.

The Notes will not be subject to any sinking fund and, except as provided in the Indenture or herein, will not be redeemable or repayable prior to their Stated Maturity.

The Notes are redeemable as a whole or in part, at the Company’s option at any time, at a Redemption Price equal to the greater of (i) 100 percent of the aggregate principal amount of the Notes being redeemed or (ii) the sum of the present values of the Remaining Scheduled Payments of principal and interest on the Notes being redeemed, discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 0.50% (50 basis points), plus, in each case, accrued and unpaid interest on the Notes to, but not including, the Redemption Date. The Company will, however, pay the interest installment due on any Interest Payment Date that occurs on or before a Redemption Date to the Holders as of the close of business on the Regular Record Date immediately preceding that Interest Payment Date.

“ Treasury Rate ” means, with respect to any Redemption Date, the rate per annum equal to the semiannual equivalent yield to maturity (computed as of the third business day immediately preceding that Redemption Date) of the Comparable Treasury Issue, assumi
