AND THIS 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 1. The Original Indenture is hereby supplemented by adding immediately after Section 20 RR, a new Section 20 SS, as follows: Section 20 SS. The Company hereby creates a forty-sixth 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, 7.20% Series due February 1, 2024" (herein sometimes referred to as the "46th Series"). The form of the bonds of the 46th Series shall be substantially as set forth in Schedule I to the supplemental indenture creating the bonds of the 46th Series. Bonds of the 46th Series shall mature on the date specified in their title. Unless otherwise determined by the Company, the bonds of the 46th 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 February and August of each year (commencing February 1, 1994) and on their maturity date. The person in whose name any bond of the 46th Series is registered at the close of business on any record date (as herein below defined) with respect to any regular semi-annual interest payment date (other than interest payable upon redemption or maturity) shall be entitled to receive the interest payable on such interest payment date notwithstanding the cancellation of such bond of the 46th 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 46th 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 46th Series shall be the registered holders of such bonds of the 46th 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 20 SS, and in the form of bonds of the 46th Series, with respect to any regular semi-annual interest payment date (other than interest payable upon redemption or maturity) shall mean the January 15 next preceding a February 1 interest payment date or the July 15 next preceding an August 1 interest payment date, as the case may be, 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 46th 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 46th Series are authorized or required by law, regulation or executive order to remain closed. Every registered bond of the 46th 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 46th 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 46th 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 46th Series ("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 or maturity) 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 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 46th 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 46th Series. The bonds of the 46th 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 X 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 supplemental indenture creating the bonds of the 46th Series. In case the Company shall at any time elect to redeem all or any part of the bonds of the 46th Series it shall give notice to the effect that it has elected to redeem all or a part thereof, as the case may be, on a date therein designated, specifying in case of redemption of a part of the bonds of 46th Series the distinctive numbers of the bonds to be redeemed, and in every case stating in substance that on said date there will become and be due and payable upon each bond so to be redeemed, at the office or agency of the Company in the Borough of Manhattan, The City of New York, the redemption price thereof (or a specified portion thereof in the case of partial redemption), and that on and after such date interest thereon will cease to accrue. The Company shall not be required to make transfers or exchanges of the bonds of the 46th Series for a period of sixteen days next preceding any selection of bonds of the 46th Series to be redeemed or to make transfers or exchanges of any bonds of the 46th Series designated in whole or in part for redemption. Notwithstanding the provisions of Section 12 of this Indenture, the Company shall not be required to make transfers or exchanges of bonds of the 46th Series for a period of sixteen days next preceding any interest payment date. Registered bonds of the 46th 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 the Company shall require it, of the charges prescribed in this Indenture, registered bonds of the 46th Series may be exchanged for a like aggregate principal amount of registered bonds of the 46th 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 from time to time designate. Section 2. The Original Indenture is hereby supplemented by adding thereto the following new Article III XXX to be added after Article III WWW of the Original Indenture: ARTICLE III XXX. Initial Issuance of Bonds of the 46th Series. Section 21 XXX. 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, bonds of the 46th Series in an aggregate principal amount not exceeding $40,000,000 shall forthwith be executed by the Company and delivered to the Trustee and shall be authenticated by the Trustee and delivered to or upon the order of the Company (without awaiting the filing and recording of the supplemental indenture creating the 46th Series except to the extent required by Section 28 of this Indenture). 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 46th Series are entitled to vote, all holders of bonds of the 46th 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 46th 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 46th 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 46th Series at the meeting, shall be entitled to receive notice of such meeting. Section 4. As supplemented by this Fourth 1993 Supplemental Indenture, the Original Indenture is in all respects ratified and confirmed and the Original Indenture and this Fourth 1993 Supplemental Indenture shall be read, taken and construed as one and the same instrument. The bonds of the 46th Series are the original debt secured by this Fourth 1993 Supplemental Indenture and the Original Indenture, and this Fourth 1993 Supplemental Indenture and the Original Indenture shall be, and be deemed to be, the original lien instrument securing the bonds of the 46th Series. Nothing contained in this Fourth 1993 Supplemental Indenture shall, or shall be construed to, confer upon any person other than the owners of bonds issued under the Original Indenture and this Fourth 1993 Supplemental Indenture, the Company and the Trustee, any right to avail themselves of any benefit of any provision of the Original Indenture or of this Fourth 1993 Supplemental Indenture.

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 June 1, 1939, executed by the Company to IRVING TRUST COMPANY (now THE BANK OF NEW YORK) and FREDERICK G. HERBST, as Trustees, 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 the affirmative vote 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 hereof of a lien upon such property or reduce the above percentage. As provided in said Mortgage, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as therein provided.

The term "Business Day" means 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 interest on bonds of this series are authorized or required by law, regulation or executive order to remain closed. 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. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of principal or (subject to the provisions hereof) interest hereon and for all other purposes and the Company and the Trustee shall not be affected by any notice to the contrary. The Company shall not be required to make transfers or exchanges of bonds of this series for a period of sixteen days next preceding any interest payment date, or next preceding any selection of bonds of this series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds of this series designated for redemption in whole or in part. Any or all of the bonds of this Series may be redeemed by the Company on or after February 1, 2004, at its option, or by operation of various provisions of the Mortgage, 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 redeemed, all as provided in the Mortgage, (a) if redeemed otherwise than by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage and otherwise than by the use of proceeds of released property or the proceeds of insurance, at an amount equal to a percentage of the principal amount thereof determined as set forth in Annex A hereto under the heading "Regular Redemption Price" together in each case with accrued interest to the date fixed for redemption, or (b) if redeemed by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage or by the use of proceeds of released property or the proceeds of insurance, at an amount equal to 100% of the principal amount thereof together in each case with accrued interest to the date fixed for redemption. The principal hereof may be declared or may become due prior to the express date of the maturity hereof on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, 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, upon surrender and cancellation of this bond and upon payment, if the Company shall require it, of the transfer charges prescribed in the Mortgage, and, thereupon, a new registered bond or bonds of authorized denominations of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. 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 of 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.

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 June 1, 1939, executed by the Company to IRVING TRUST COMPANY (now THE BANK OF NEW YORK) and FREDERICK G. HERBST, as Trustees, 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 the affirmative vote 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 hereof of a lien upon such property or reduce the above percentage. As provided in said Mortgage, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as therein provided.

The interest payable on any February 1 or August 1 (other than interest payable upon redemption) will, subject to certain exceptions provided in said First 1994 Supplemental Indenture, be paid to the person in whose name this bond is registered at the close of business on the record date, which shall be 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 hereinbelow defined), the next preceding Business Day.

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. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of principal or (subject to the provisions hereof) interest hereon and for all other purposes and the Company and the Trustee shall not be affected by any notice to the contrary. The Company shall not be required to make transfers or exchanges of bonds of this series for a period of sixteen days next preceding any interest payment date, or next preceding any selection of bonds of this series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds of this series designated for redemption in whole or in part. Any or all of the bonds of this Series may be redeemed by the Company on or after March 1, 2004, at its option, or by operation of various provisions of the Mortgage, 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 redeemed, all as provided in the Mortgage, (a) if redeemed otherwise than by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage and otherwise than by the use of proceeds of released property or the proceeds of insurance, at an amount equal to a percentage of the principal amount thereof determined as set forth in Annex A hereto under the heading "Regular Redemption Price" together in each case with accrued interest to the date fixed for redemption, or (b) if redeemed by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage or by the use of proceeds of released property or the proceeds of insurance, at an amount equal to 100% of the principal amount thereof together in each case with accrued interest to the date fixed for redemption. The principal hereof may be declared or may become due prior to the express date of the maturity hereof on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, 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, upon surrender and cancellation of this bond and upon payment, if the Company shall require it, of the transfer charges prescribed in the Mortgage, and, thereupon, a new registered bond or bonds of authorized denominations of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage.

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 June 1, 1939, executed by the Company to IRVING TRUST COMPANY (now THE BANK OF NEW YORK) and FREDERICK G. HERBST, as Trustees, 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 the affirmative vote 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 hereof of a lien upon such property or reduce the above percentage. As provided in said Mortgage, said bonds may be for various principal sums and are issuable in series, which may mature at different times, may bear interest at different rates and may otherwise vary as therein provided. This bond is created by an Indenture Supplemental dated as of February 1, 1994 (the "First 1994 Supplemental Indenture"), as provided for in said Mortgage. The interest payable on any February 1 or August 1 (other than interest payable upon redemption) will, subject to certain exceptions provided in said First 1994 Supplemental Indenture, be paid to the person in whose name this bond is registered at the close of business on the record date, which shall be 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 hereinbelow defined), the next preceding Business Day. Interest payable upon redemption or maturity shall be payable to the person to whom principal is paid. The term "Business Day" means 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 interest on bonds of this series are authorized or required by law, regulation or executive order to remain closed. 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. The Company and the Trustee may deem and treat the person in whose name this bond is registered as the absolute owner hereof for the purpose of receiving payment of or on account of principal or (subject to the provisions hereof) interest hereon and for all other purposes and the Company and the Trustee shall not be affected by any notice to the contrary. The Company shall not be required to make transfers or exchanges of bonds of this series for a period of sixteen days next preceding any interest payment date, or next preceding any selection of bonds of this series to be redeemed, and the Company shall not be required to make transfers or exchanges of any bonds of this series designated for redemption in whole or in part. Any or all of the bonds of this Series may be redeemed by the Company on or after March 1, 1999, at its option, or by operation of various provisions of the Mortgage, 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 redeemed, all as provided in the Mortgage, (a) if redeemed otherwise than by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage and otherwise than by the use of proceeds of released property or the proceeds of insurance, at an amount equal to a percentage of the principal amount thereof determined as set forth in Annex A hereto under the heading "Regular Redemption Price" together in each case with accrued interest to the date fixed for redemption, or (b) if redeemed by the use or application of cash deposited pursuant to the maintenance and replacement provisions contained in Part II(a) of Section 20 of the Mortgage or by the use of proceeds of released property or the proceeds of insurance, at an amount equal to 100% of the principal amount thereof together in each case with accrued interest to the date fixed for redemption. The principal hereof may be declared or may become due prior to the express date of the maturity hereof on the conditions, in the manner and at the time set forth in the Mortgage, upon the occurrence of a completed default as in the Mortgage provided. This bond is transferable as prescribed in the Mortgage by the registered owner hereof in person, or by his duly authorized attorney, 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, upon surrender and cancellation of this bond and upon payment, if the Company shall require it, of the transfer charges prescribed in the Mortgage, and, thereupon, a new registered bond or bonds of authorized denominations of the same series for a like principal amount will be issued to the transferee in exchange herefor as provided in the Mortgage. 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 of 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. This bond shall not become valid or obligatory for any purpose until THE BANK OF NEW YORK, the Trustee under the Mortgage, or its successor thereunder, shall have signed the form of Authentication Certificate endorsed hereon.
