This bond is one of a duly authorized issue of bonds of the Company, issuable in series, and is one of a series known as its First Mortgage Bonds, of the series designated in its title, all bonds of all series issued and to be issued under and equally secured (except in so far as any sinking fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust (herein, together with any indentures supplemental thereto, called the Mortgage), dated as of October 1, 1938, executed by the Company to CENTRAL HANOVER BANK AND TRUST COMPANY (now CHEMICAL BANK), as Trustee, to which Mortgage reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee, and the terms and conditions upon which the bonds are secured.

The Company hereby creates a fiftieth 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, 6.15% Series due December 1, 2003" (herein called bonds of the 50th Series). The form of the bonds of the 50th Series shall be substantially as set forth in Schedule I to the Fifth 1993 Supplemental Indenture. Bonds of the 50th Series shall mature on the date specified in their title. Unless otherwise determined by the Company, the bonds of the 50th 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 each said bond to be payable at the office or agency of the Company in the Borough of Manhattan, The City of New York, in lawful money of the United States of America, 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 April and October of each year (commencing April 1, 1994) and on their maturity date. The person in whose name any bond of the 50th 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 50th 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 50th 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 50th Series shall be the registered holders of such bonds of the 50th 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. Interest payable upon redemption or maturity shall be payable to the person to whom the principal is paid. The term "record date" as used in this Section 20XX, and in the form of the bonds of the 50th Series, with respect to any regular semi-annual interest payment date (other than interest payable upon redemption) applicable to the bonds of the 50th Series, shall mean the March 20 next preceding an April 1 interest payment date or the September 20 next preceding an October 1 interest payment date, as the case may be, or, if such March 20 or September 20 is not a Business Day (as defined hereinbelow), the next preceding Business Day.

Every registered bond of the 50th 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 50th 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 50th 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 50th 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 (other than interest payable upon redemption) and such interest payment date shall not be entitled to the payment of the interest due on such interest payment date 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 April 1 or October 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 50th 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 50th Series.

Section 3. At any meeting of bondholders held as provided for in Article XVIII of the Original Indenture at which holders of bonds of the 50th Series are entitled to vote, all holders of bonds of the 50th 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 50th 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 50th 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 50th Series at the meeting, shall be entitled to receive notice of such meeting.

This bond is one of a duly authorized issue of bonds of the Company, issuable in series, and is one of a series known as its First Mortgage Bonds, of the series designated in its title, all bonds of all series issued and to be issued under and equally secured (except in so far as any sinking fund, established in accordance with the provisions of the Mortgage hereinafter mentioned, may afford additional security for the bonds of any particular series) by a Mortgage and Deed of Trust (herein, together with any indentures supplemental thereto, called the Mortgage), dated as of October 1, 1938, executed by the Company to CENTRAL HANOVER BANK AND TRUST COMPANY (now CHEMICAL BANK), as Trustee, to which Mortgage reference is made for a description of the property mortgaged and pledged, the nature and extent of the security, the rights of the holders of the bonds and of the Trustee in respect thereof, the duties and immunities of the Trustee, and the terms and conditions upon which the bonds are secured. With the consent of the Company and to the extent permitted by and as provided in the Mortgage, the rights and obligations of the Company and/or of the holders of the bonds and/or coupons and/or the terms and provisions of the Mortgage and/or of any instruments supplemental thereto may be modified or altered by affirmative vote, or written consent, of the holders of at least seventy-five per centum (75%) in principal amount of the bonds affected by such modification or alteration then outstanding under the Mortgage (excluding bonds disqualified from voting by reason of the Company's interest therein as provided in the Mortgage); provided that, without the consent of the holder hereof, no such modification or alteration shall permit the extension of the maturity of the principal of or interest on this bond or the reduction in the rate of interest hereon or any other modification in the terms of payment of such principal or interest or the creation of a lien on the mortgaged and pledged property ranking prior to or on a parity with the lien of the Mortgage or the deprivation of the holder of a lien upon such property or reduce the above percentage.

In the manner and upon payment, if the Company shall require it, of the charges prescribed in the Mortgage registered bonds of this series may be exchanged for a like aggregate principal amount of registered bonds of other authorized denominations of the same series, 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, or at such other office or agency of the Company as the Company may designate. No recourse shall be had for the payment of the principal of or interest on this bond against any incorporator or any past, present or future stockholder, officer or director, as such, of the Company, or any successor corporation, either directly or through the Company or any successor corporation, under any rule of law, statute or constitution or by the enforcement of any assessment or otherwise, all such liability of incorporators, stockholders, officers and directors, as such, being waived and released by the holder or owner hereof by the acceptance of this bond and being likewise waived and released by the terms of the Mortgage.
