And this Third 1993 Supplemental Indenture further Witnesseth: That in further consideration of the premises and for the considerations aforesaid, the Company, for itself and its successors and assigns, hereby covenants and agrees to and with the Trustee, and its successor or successors in such trust, as follows: Section 8. The Original Indenture is hereby supplemented by adding immediately after Section 19N, a new Section 19O, as follows: Section 19O. The Company hereby creates a sixteenth series of bonds to be issued under and secured by this Indenture, to be designated and to be distinguished from the bonds of all other series by the title "First Mortgage Bonds, Designated Secured Medium Term Notes, 7.90% Series due June 1, 2023" (herein called bonds of the Sixteenth Series). The form of the bonds of the Sixteenth Series shall be substantially as set forth in Schedule I to the Third 1993 Supplemental Indenture. The bonds of the Sixteenth Series shall mature on the date specified in their title. Unless otherwise determined by the Company, the bonds of the Sixteenth Series shall be issued in fully registered form without coupons in denominations of $1,000 and integral multiples thereof; the principal of and premium (if any) and interest on the bonds of the Sixteenth Series shall be payable in lawful money of the United States of America; principal and premium (if any) and interest shall be payable at the office or agency of the Company in said Borough of Manhattan, The City of New York, provided that at the option of the Company interest may be mailed to registered owners of the bonds at their respective addresses that appear on the register thereof; and the rate of interest shall be the rate per annum specified in the title thereof, payable semi- annually on the first days of February and August of each year (commencing August 1, 1993) and on their maturity date. The person in whose name any bond of the Sixteenth Series is registered at the close of business on any record date (as hereinbelow defined) with respect to any regular semi-annual interest payment date (other than interest payable upon redemption) shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such bond of the Sixteenth Series upon any registration of transfer or exchange thereof (including any exchange effected as an incident to a partial redemption thereof) subsequent to the record date and prior to such interest payment date, except, if and to the extent that the Company shall default in the payment of the interest due on such interest payment date, then the registered holders of bonds of the Sixteenth Series on such record date shall have no further right to or claim in respect of such defaulted interest as such registered holders on such record date, and the persons entitled to receive payment of any defaulted interest thereafter payable or paid on any bonds of the Sixteenth Series shall be the registered holders of such bonds of the Sixteenth Series (or any bond or bonds issued, directly or after intermediate transactions, upon transfer or exchange or in substitution thereof) on the date of payment of such defaulted interest. The term "record date" as used in this Section 19O, and in the form of Bonds of the Sixteenth Series, with respect to any regular semi-annual interest payment date (other than interest payable upon redemption) shall mean the January 15 or July 15, as the case may be, next preceding such interest payment date, or, if such January 15 or July 15 is not a Business Day (as defined hereinbelow), the next preceding Business Day. The term "Business Day" with respect to any bond of the Sixteenth Series shall mean any day, other than a Saturday or Sunday, which is not a day on which banking institutions or trust companies in The City of New York, New York or the city in which is located any office or agency maintained for the payment of principal of or premium, if any, or interest on such bond of the Sixteenth Series are authorized or required by law, regulation or executive order to remain closed. Every registered bond of the Sixteenth Series shall be dated the date of authentication ("Issue Date") and shall bear interest computed on the basis of a 360-day year consisting of twelve 30-day months from its Issue Date or from the latest semi-annual interest payment date to which interest has been paid on the bonds of the Sixteenth Series preceding the Issue Date, unless such Issue Date be an interest payment date to which interest is being paid on the bonds of the Sixteenth Series, in which case it shall bear interest from its Issue Date; or unless the Issue Date be the record date for the interest payment date first following the date of original issuance of bonds of the Sixteenth Series (the "Original Issue Date") or a date prior to such record date, then from the Original Issue Date; provided, that, so long as there is no existing default in the payment of interest on said bonds, the holder of any bond authenticated by the Trustee between the record date for any regular semi-annual interest payment date and such interest payment date shall not be entitled to the payment of the interest due on such interest payment date (other than interest payable upon redemption) and shall have no claim against the Company with respect thereto; provided, further, that, if and to the extent the Company shall default in the payment of the interest due on such interest payment date, then any such bond shall bear interest from the February 1 or August 1, as the case may be, next preceding its Issue Date, to which interest has been paid or, if the Company shall be in default with respect to the interest payment date first following the Original Issue Date, then from the Original Issue Date. If any semi-annual interest payment date, redemption date, or the maturity date is not a Business Day, payment of amounts due on such date may be made on the next succeeding Business Day, and, if such payment is made or duly provided for on such Business Day, no interest shall accrue on such amounts for the period from and after such interest payment date, redemption date, or the maturity date, as the case may be, to such Business Day. Notwithstanding the provisions of Section 14 of this Indenture, the bonds of the Sixteenth Series shall be executed on behalf of the Company by its Chairman of the Board, by its President or by one of its Vice Presidents or by one of its officers designated by the Board of Directors of the Company for such purpose, whose signature may be a facsimile, and its corporate seal shall be thereunto affixed or printed thereon and attested by its Secretary or one of its Assistant Secretaries, and the provisions of the penultimate sentence of said Section 14 shall be applicable to such bonds of the Sixteenth Series. The bonds of the Sixteenth Series shall be redeemable prior to maturity at the option of the Company in whole at any time or in part from time to time, upon not less than thirty but not more than ninety days' previous notice given by mail to the registered holders of the bonds to be so redeemed, to the addresses that shall appear upon the register thereof, all as provided in Article XII of this Indenture, and as in this section provided, and as further set forth in the form of bond contained in Schedule I to the Third 1993 Supplemental Indenture. Notwithstanding the provisions of Section 12 of this Indenture, the Company shall not be required to make transfers or exchanges of bonds of the Sixteenth Series for a period of fifteen days next preceding any interest payment date or next preceding any selection of bonds of the Sixteenth Series to be redeemed and the Company shall not be required to make transfers or exchanges of bonds of the Sixteenth Series designated for redemption in whole or in part. Registered bonds of the Sixteenth Series shall be transferable upon presentation and surrender thereof, for cancellation, at the office or agency of the Company in the Borough of Manhattan, The City of New York, and at such other office or agency of the Company as the Company may designate, by the registered holders thereof, in person or by duly authorized attorney, in the manner and upon payment, if required by the Company, of the charges prescribed in this Indenture. In the manner and upon payment, if required by the Company, of the charges prescribed in this Indenture, registered bonds of the Sixteenth Series may be exchanged for a like aggregate principal amount of registered bonds of the Sixteenth Series of other authorized denominations, upon presentation and surrender thereof, for cancellation, at the office or agency of the Company in the Borough of Manhattan, The City of New York and at such other office or agency of the Company as the Company may designate. Section 9. The Original Indenture is hereby supplemented by adding immediately after Section 21M thereof Section 21N, as follows: Section 21N. In accordance with and upon compliance with such provisions of this Indenture as shall be selected for such purpose by the officers of the Company duly authorized to take such action, $25,000,000 principal amount of the bonds of the Sixteenth Series shall forthwith be executed by the Company and delivered to the Trustee and shall be authenticated by the Trustee and delivered from time to time in accordance with the order or orders of the Company evidenced by a writing or writings signed in the name of the Company by its President or one of its Vice Presidents and its Treasurer or one of its Assistant Treasurers (without awaiting the filing or recording of the Third 1993 Supplemental Indenture except to the extent required by Section 28 of this Indenture). Section 10. At any meeting of bondholders held as provided for in Article XX of the Original Indenture at which holders of bonds of the Sixteenth Series are entitled to vote, all holders of bonds of the Sixteenth Series at the time of such meeting shall be entitled to vote thereat; provided, however, that the Trustee may, and upon request of the Company or of a majority of the bondholders of the Sixteenth Series shall, fix a day not exceeding ninety days preceding the date for which the meeting is called as a record date for the determination of holders of bonds of the Sixteenth Series entitled to notice of and to vote at such meeting and any adjournment thereof and only such registered owners who shall have been such registered owners on the date so fixed, and who are entitled to vote such bonds of the Sixteenth Series at the meeting, shall be entitled to receive notice of such meeting. Section 11. As supplemented by this Third 1993 Supplemental Indenture, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Third 1993 Supplemental Indenture shall be read, taken and construed as one and the same instrument. The bonds of the Sixteenth Series are the original debt secured by this Third 1993 Supplemental Indenture and the Original Indenture, and this Third 1993 Supplemental Indenture and the Original Indenture shall be, and be deemed to be, the original lien instrument securing the bonds of the Sixteenth Series. Nothing in this Third 1993 Supplemental Indenture contained shall, or shall be construed to, confer upon any person other than the holders of bonds issued under the Original Indenture and this Third 1993 Supplemental Indenture, the Company and the Trustee, any right to avail themselves of any benefit of any provisions of the Original Indenture or of this Third 1993 Supplemental Indenture. This Third 1993 Supplemental Indenture may be simultaneously executed in any number of counterparts, each of which when so executed shall be deemed to be an original; but such counterparts shall together constitute but one and the same instrument.
