ANNEX I

Capitalized terms used in this Annex I and not otherwise defined herein have the same definitions as in the Indenture referred to in the Officers’ Certificate of which this Annex I constitutes a part.

(1)                               On March 11, 2005, the Company issued $100,000,000 aggregate principal amount of a series of debt securities under the Indenture known and designated as the “57/8% Senior Debentures due 2035” (the “Prior Securities”), all of which are currently outstanding.  Pursuant to this Annex I and the Officers’ Certificate of which this Annex I constitutes a part, the Company is reopening such series of debt securities and issuing additional debt securities of such series in an aggregate principal amount of $150,000,000 (the “New Securities”) (which New Securities shall also be part of the series designated as “57/8% Senior Debentures due 2035”), such that the Prior Securities and the New Securities shall constitute a single series of debt securities under the Indenture and the New Securities shall have the same terms as the prior securities except for original issue date and date from which interest shall begin to accrue.  As used herein, the term “Securities” means the Prior Securities, the New Securities and any additional debt securities of such series which may be issued upon a reopening of such series, or any of them, as the context shall require.

(2)                               The aggregate principal amount of the New Securities of such series which may be authenticated and delivered under the Indenture is limited to $150,000,000, thereby increasing the authorized aggregate principal amount of the Securities of such series to $250,000,000, except in each case for Securities of such series authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Securities of the same series pursuant to Sections 304, 305, 306, 906 or 1107 of the Indenture.  However, such series may be reopened by the Company for the issuance of additional Securities of such series, so long as any such additional Securities have the same form and terms (other than the date of issuance and the date from which interest thereon shall begin to accrue), and carry the same right to receive accrued and unpaid interest, as the Securities of such series theretofore issued; provided, however, that, notwithstanding the foregoing, such series may not be reopened if the Company has effected defeasance or covenant defeasance with respect to the Securities of such series pursuant to Section 1402 and 1403, respectively, of the Indenture or has effected satisfaction and discharge with respect to the Securities of such series pursuant to Section 401 of the Indenture.

(3)                               The New Securities of such series are to be issuable only as Registered Securities without coupons and may, but need not, bear a corporate seal.  The New Securities of such series shall initially be issued in book-entry form and represented by one or more permanent Global Securities of such series, the initial depositary (the “Depositary”) for the Global Securities of such series shall be The Depository Trust Company and the depositary arrangements shall be those employed by whoever shall be the Depositary with respect to the Global Securities of such series from time to time.  Notwithstanding the foregoing, certificated New Securities of such series in definitive form may be issued in exchange for Global Securities of such series under the circumstances contemplated by Section 305 of the Indenture.

(4)                               The New Securities of such series shall be sold by the Company to the several underwriters named in the Purchase Agreement dated June 14, 2011, for whom Citigroup Global Markets Inc., J.P. Morgan Securities LLC and Merrill Lynch, Pierce, Fenner & Smith Incorporated are acting as representatives, at a price equal to 93.703% of the principal amount thereof plus accrued interest from and including March 15, 2011 to but excluding June 17, 2011, and the initial price to public of the New Securities of such series shall be 94.578% of the principal amount thereof plus accrued interest from and including March 15, 2011 and underwriting discounts and commissions shall be 0.875% of the principal amount of such New Securities.

(5)                               The final maturity date of the New Securities of such series on which the principal thereof is due and payable shall be March 15, 2035.

(6)                               The principal of the New Securities of such series shall bear interest at the rate of 57/8% per annum from March 15, 2011 or from the most recent date to which interest has been paid or duly provided for, payable semiannually in arrears on March 15 and September 15 (each, an “Interest Payment Date”) of each year, commencing September 15, 2011, to the Persons in whose names such Securities (or one or more Predecessor Securities) are registered at the close of business on the March 1 or September 1, respectively, immediately prior to such Interest Payment Dates (each, a “Regular Record Date”) regardless of whether such Regular Record Date is a Business Day.  Interest on the New Securities of such series will be computed on the basis of a 360-day year of twelve 30-day months.  If any principal of, or premium, if any, or interest on, any of the New Securities of such series is not paid when due, then such overdue principal and, to the extent permitted by law, such overdue premium or interest, as the case may be, shall bear interest until paid or until such payment is duly provided for at the rate of 57/8% per annum.

(24)                        Insofar as Section 801 of the Indenture is applicable to the New Securities of such series, the term “Subsidiary,” as used in Section 801(2) of the Indenture, shall have the meaning set forth in the form of New Security of such series attached as Annex II to the Officers’ Certificate of which this Annex I is a part (instead of the meaning set forth in Section 101 of the Indenture), and the term “indebtedness,” as used in Section 801(2) of the Indenture, shall be deemed to include, without limitation, “Debt” and “Secured Debt” (as such terms are defined in the form of Security of such series attached as Annex II to the Officers’ Certificate of which this Annex I is a part ).

(25)                        The provisions of Section 1011 of the Indenture shall be applicable with respect to any term, provision or condition set forth in the Additional Covenants, in addition to any term, provision and condition set forth in Sections 1004 to 1008, inclusive, of the Indenture.

(27)                        As used in the Indenture with respect to the New Securities of such series and in the certificates evidencing the Securities of such series, all references to “premium” on the New Securities of such series shall mean any amounts (other than accrued interest) payable upon the redemption of any New Securities of such series in excess of 100% of the principal amount of such Securities.
