The Company further covenants and agrees to and with the Trustee and its successor or successors in such trust under the Mortgage, as follows:

SECTION 1.01. There shall be a series of bonds designated “2.95% Series due 2022” (herein sometimes referred to as the Thirty-Ninth Series), each of which shall also bear the descriptive title “First Mortgage Bond,” and the form thereof, which shall be established by or pursuant to a Resolution, shall contain suitable provisions with respect to the matters hereinafter in this Section specified.

(I) Bonds of the Thirty-Ninth Series shall mature on February 1, 2022 and shall be issued as fully registered bonds in the minimum denomination of two thousand dollars and, at the option of the Company, any multiple or multiples of one thousand dollars in excess thereof (the exercise of such option to be evidenced by the execution and delivery thereof).

The Company reserves the right to establish, at any time, by or pursuant to a Resolution filed with the Trustee, a form of coupon bond, and or appurtenant coupons, for the Thirty-Ninth Series and to provide for exchangeability of such coupon bonds with the bonds of the Thirty-Ninth Series issued hereunder in fully registered form and to make all appropriate provisions for such purpose.

Bonds of the Thirty-Ninth Series need not be issued at the same time and such series may be reopened at any time, without notice to or the consent of any then-existing holder or holders of any bond of the Thirty-Ninth Series, for issuances of additional bonds of the Thirty-Ninth Series in an unlimited principal amount. Any such additional bonds will have the same interest rate, maturity and other terms as those initially issued, except for payment of interest accruing prior to the original issue date of such additional bonds and, if applicable, for the first interest payment date following such original issue date.

(II) Bonds of the Thirty-Ninth Series shall bear interest at the rate of two and ninety-five hundredths per centum (2.95%) per annum payable semi-annually in arrears on February 1 and August 1 of each year (each, an “Interest Payment Date”). Bonds of the Thirty-Ninth Series shall be dated and shall accrue interest as provided in Section 2.06 of the Mortgage.

The initial Interest Payment Date is August 1, 2012. The amount of interest payable will be computed on the basis of a 360-day year consisting of twelve 30-day months. If any date on which interest is payable on any bond of the Thirty-Ninth Series is not a Business Day, then payment of the interest payable on that date will be made on the next succeeding day which is a Business Day (and without any additional interest or other payment in respect of any delay), with the same force and effect as if made on such date.

Interest payable on any bond of the Thirty-Ninth Series and punctually paid or duly provided for on any Interest Payment Date for such bond will be paid to the person in whose name the bond is registered at the close of business on the Record Date (as hereinafter specified) for such bond next preceding such Interest Payment Date; provided, however, that interest payable at maturity or upon earlier redemption will be payable to the person to whom principal shall be payable. So long as the bonds of the Thirty-Ninth Series remain in book-entry only form, the “Record Date” for each Interest Payment Date shall be the close of business on the Business Day before the applicable Interest Payment Date. If the bonds of the Thirty-Ninth Series are not in book-entry only form, the Record Date for each Interest Payment Date shall be the close of business on the 15^th calendar day of the month immediately preceding the month in which the applicable Interest Payment Date occurs (whether or not a Business Day).

“Business Day” means, for purposes of this Section (II), a day other than (i) a Saturday or a Sunday, or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

Any interest on any bond of the Thirty-Ninth Series which is payable but is not punctually paid or duly provided for, on any Interest Payment Date for such bond (herein called “Defaulted Interest”), shall forthwith cease to be payable to the registered owner on the relevant Record Date for the payment of such interest solely by virtue of such owner having been such owner; and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in subsection (i) or (ii) below:

Subject to the foregoing provisions of this Section, each bond of the Thirty-Ninth Series delivered under the Mortgage upon transfer of or in exchange for or in lieu of any other bond shall carry all rights to interest accrued and unpaid, and to accrue, which were carried by such other bond and each such bond shall bear interest from such date, that neither gain nor loss in interest shall result from such transfer, exchange or substitution.

(III) The principal of and interest and premium, if any, on each bond of the Thirty-Ninth Series shall be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in such coin or currency of the United States of America as at the time of payment is legal tender for public and private debts or in such other currency or currency unit as shall be determined by or in accordance with the Resolution filed with the Trustee.

(IV) Bonds of the Thirty-Ninth Series shall not be redeemable prior to maturity at the option of any holder or holders of such bonds. Bonds of the Thirty-Ninth Series shall be redeemable in whole or in part and at any time prior to maturity at the option of the Company. Prior to November 1, 2021, the redemption price shall include accrued and unpaid interest to the redemption date on the bonds to be redeemed, plus the greater of (a) one hundred per centum (100%) of the principal amount of bonds then Outstanding to be redeemed, or (b) the sum of the present values of the remaining scheduled payments of principal and interest thereon (not including any portion of such payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Adjusted Treasury Rate, plus 15 basis points, as calculated by an Independent Investment Banker. At any time on or after November 1, 2021, the redemption price shall include accrued and unpaid interest to the redemption date on the bonds to be redeemed, plus one hundred percent (100%) of the principal amount of bonds then Outstanding to be redeemed. The Company shall give the Trustee notice of the redemption price referred to in the second preceding sentence immediately after the calculation thereof, and the Trustee shall have no responsibility for such calculation. If the Company elects to partially redeem the bonds of the Thirty-Ninth Series, the Trustee shall select in a fair and appropriate manner the bonds of the Thirty-Ninth Series to be redeemed.

    “Adjusted Treasury Rate” means, with respect to any redemption date, the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month); or if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum 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 Adjusted Treasury Rate will be calculated on the third Business Day preceding the redemption date.

“Business Day” means, for purposes of this Section (IV), a day other than (i) a Saturday or a Sunday, or (ii) a day on which banking institutions in The City of New York are authorized or obligated by law or executive order to remain closed.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the bonds of the Thirty-Ninth Series to be redeemed that would be used, 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 such bonds (the “Remaining Life”).

“Comparable Treasury Price” means, with respect to any redemption date, (a) the average of four Reference Treasury Dealer Quotations for such redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (b) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by the Company and its successors, or if that firm is unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, 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 Independent Investment Banker at 5:00 p.m., New York City time, on the third Business Day preceding such redemption date.

(V) Each bond of the Thirty-Ninth Series may have such other terms as are not inconsistent with Section 2.03 of the Mortgage, and as may be determined by or in accordance with a Resolution filed with the Trustee.

    

(VI) At the option of the registered owner, any bonds of the Thirty-Ninth Series, upon surrender thereof for cancellation at the office or agency of the Company in the Borough of Manhattan, The City of New York, shall be exchangeable for a like aggregate principal amount of bonds of the same series and same terms of other authorized denominations.

(VII) Bonds of the Thirty-Ninth Series shall be transferable, subject to any restrictions thereon set forth in any such bond of the Thirty-Ninth Series, upon the surrender thereof for cancellation, together with a written instrument of transfer, if required by the Company, duly executed by the registered owner or by his, her or its duly authorized attorney, at the office or agency of the Company in the Borough of Manhattan, The City of New York. Upon any transfer or exchange of bonds of the Thirty-Ninth Series, the Company may make a charge therefor sufficient to reimburse it for any tax or taxes or other government charge, as provided in Section 2.08 of the Mortgage, but the Company hereby waives any right to make a charge in addition thereto for any exchange or transfer of bonds of the Thirty-Ninth Series.

(VIII) After the execution and delivery of this Twenty-Fifth Supplemental Indenture and upon compliance with the applicable provisions of the Mortgage and this Twenty-Fifth Supplemental Indenture, it is contemplated that there shall be issued bonds of the Thirty-Ninth Series in an initial aggregate principal amount of Three Hundred Fifty Million Dollars (U.S. $350,000,000).

SECTION 2.01. There shall be a series of bonds designated “4.10% Series due 2042” (herein sometimes referred to as the Fortieth Series), each of which shall also bear the descriptive title “First Mortgage Bond,” and the form thereof, which shall be established by or pursuant to a Resolution, shall contain suitable provisions with respect to the matters hereinafter in this Section specified.

(I) Bonds of the Fortieth Series shall mature on February 1, 2042 and shall be issued as fully registered bonds in the minimum denomination of two thousand dollars and, at the option of the Company, any multiple or multiples of one thousand dollars in excess thereof (the exercise of such option to be evidenced by the execution and delivery thereof).

The Company reserves the right to establish, at any time, by or pursuant to a Resolution filed with the Trustee, a form of coupon bond, and or appurtenant coupons, for the Fortieth Series and to provide for exchangeability of such coupon bonds with the bonds of the Fortieth Series issued hereunder in fully registered form and to make all appropriate provisions for such purpose.

Bonds of the Fortieth Series need not be issued at the same time and such series may be reopened at any time, without notice to or the consent of any then-existing holder or holders of any bond of the Fortieth Series, for issuances of additional bonds of the Fortieth Series in an unlimited principal amount.

(II) Bonds of the Fortieth Series shall bear interest at the rate of four and ten hundredths per centum (4.10%) per annum payable semi-annually in arrears on February 1 and August 1 of each year (each, an “Interest Payment Date”).

The initial Interest Payment Date is August 1, 2012. The amount of interest payable will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Interest payable on any bond of the Fortieth Series and punctually paid or duly provided for on any Interest Payment Date for such bond will be paid to the person in whose name the bond is registered at the close of business on the Record Date (as hereinafter specified) for such bond next preceding such Interest Payment Date; provided, however, that interest payable at maturity or upon earlier redemption will be payable to the person to whom principal shall be payable. So long as the bonds of the Fortieth Series remain in book-entry only form, the “Record Date” for each Interest Payment Date shall be the close of business on the Business Day before the applicable Interest Payment Date. If the bonds of the Fortieth Series are not in book-entry only form, the Record Date for each Interest Payment Date shall be the close of business on the 15^th calendar day of the month immediately preceding the month in which the applicable Interest Payment Date occurs (whether or not a Business Day).
