The terms and conditions set forth herein will apply to each Offered Note. Capitalized terms not defined under this heading have the meanings assigned to them in the Prospectus or the Indenture (the "Senior Note Indenture"), dated as of November 15, 1996, between the Company and The Bank of New York, as Trustee (the "Senior Note Trustee"). General The Offered Notes offered hereby will be issued under the Senior Note Indenture as supplemented by the First Supplemental Indenture, dated as of November 15, 1996, the Second Supplemental Indenture dated as of April 1, 1997, and the Third Supplemental Indenture, dated as of , (collectively, the "Supplemental Indentures"), between the Company and the Senior Note Trustee. The Offered Notes constitute a single series for purposes of the Senior Note Indenture, limited to an aggregate principal amount not to exceed $ . The Offered Notes will initially be represented by a Global Note that will be deposited with, or on behalf of, The Depository Trust Company (the "Depositary"). See "Description of Senior Notes -- Global Notes" in the accompanying Prospectus. The Offered Notes will be issuable in denominations of $1,000 and any integral multiple thereof. The Offered Notes will mature on (the "Maturity"). The Offered Notes will bear interest from and including or from and including the most recent Interest Payment Date with respect to which interest on such Offered Note (or any predecessor Offered Note) has been paid or duly provided for to, but excluding, the relevant Interest Payment Date at % per annum until the principal thereof is paid or made available for payment. The Interest Payment Dates will be and of each year, commencing . Interest will be payable to the person (which, in the case of the Global Note, shall be the Depositary) in whose name an Offered Security is registered at the close of business on or (each, a "Regular Record Date") next preceding such Interest Payment Date; provided, however, that the interest payable at Maturity will be payable to the person to whom principal shall be payable. The amount of interest payable for any period will be computed on the basis of a 360-day year of twelve 30-day months. Redemption The Offered Notes may be redeemed at any time at the option of the Company, in whole or from time to time in part, at a redemption price equal to the sum of (i) the principal amount of the Offered S-2 Notes (or portion thereof) being redeemed plus accrued interest thereon to the redemption date and (ii) the Make-Whole Amount (as defined below), if any, with respect to the Offered Notes (or portion thereof) being redeemed (the "Redemption Price"). If notice has been given as provided in the Senior Note Indenture and funds for the redemption of any Offered Notes (or any portion thereof) called for redemption shall have been made available on the redemption date referred to in such notice, such Offered Notes (or any portion thereof) will cease to bear interest on the date fixed for such redemption specified in such notice and the only right of the Holders of such Offered Notes will be to receive payment of the Redemption Price. Notice of any optional redemption of any Offered Notes (or any portion thereof) will be given to Holders at their addresses, as shown in the security register for such Offered Notes, not more than 60 nor less than 30 days prior to the date fixed for redemption. The notice of redemption will specify, among other items, the Redemption Price and the principal amount of the Offered Notes held by such Holder to be redeemed. If less than all of the Offered Notes are to be redeemed at the option of the Company, the Trustee shall select, in such manner as it shall deem fair and appropriate, such Offered Notes to be redeemed in whole or in part. As used herein: "Make-Whole Amount" means, in connection with any optional redemption of any Offered Notes, the excess, if any, of (i) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third Business Day preceding the date such notice of redemption is given) from the respective dates on which such principal and interest would have been payable if such redemption had not been made, over (ii) the aggregate principal amount of the Offered Notes being redeemed. "Reinvestment Rate" means % plus the arithmetic mean of the yields under the respective heading "Week Ending" published in the most recent Statistical Release under the caption "Treasury Constant Maturities" for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity, as of the payment date of the principal being redeemed. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of such relevant periods to the nearest month. For the purpose of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make- Whole Amount shall be used. "Statistical Release" means the statistical release designed "H.15(519)" or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities, or, if such statistical release is not published at the time of any determination under the Indenture, then such other reasonably comparable index which shall be designated by the Company. The Offered Notes will not be subject to any sinking fund. Security Upon the issuance of the Offered Notes, the Company will simultaneously issue and deliver to the Senior Note Trustee, as security for the Offered Notes, First Mortgage Bonds, Senior Note Series (the "Series First Mortgage Bonds"). The Series First Mortgage Bonds will have the same interest rate, Interest Payment Dates, Maturity and redemption provisions, and will be in the same aggregate principal amount as the Offered Notes. Subject to the provisions of the Senior Note Indenture governing disbursement of funds following an event of default, payment by the Company to the Senior Note Trustee of the principal and interest on the S-3 Series First Mortgage Bonds will be applied by the Senior Note Trustee to satisfy the Company's obligations with respect to the principal and interest on the Offered Notes. As provided in the supplemental indenture setting forth the terms of the Series First Mortgage Bonds, the Company's obligation to make payments with respect to the principal, premium, and/or interest on the Series First Mortgage Bonds shall be fully or partially, as the case may be, satisfied and discharged to the extent that, at the time that any such payment shall be due, the corresponding amount of principal, premium, if any, and/or interest then due, on the Offered Notes shall have been fully or partially paid, as the case may be, or there shall have been deposited with the Senior Note Trustee pursuant to the Senior Note Indenture trust funds sufficient under the provisions of the Senior Note Indenture to fully or partially pay the corresponding amount of principal, premium, if any, and/or interest then due on the Offered Notes. Reference is made to "Description Of Senior Notes -- Release Date" in the accompanying Prospectus for a description of the circumstances under which all or part of the Senior Note Mortgage Bonds will cease to be held by the Senior Note Trustee as security for the Senior Notes. As explained in the Prospectus, the Senior Notes will cease to be secured by the Senior Note Mortgage Bonds on the Release Date and will become unsecured general obligations of the Company. The Release Date will be the date that all First Mortgage Bonds of the Company issued and outstanding under the Mortgage, other than Senior Note Mortgage Bonds, have been retired (at, before or after the maturity thereof) through payment, redemption or otherwise.
