8

the manner and upon the conditions prescribed in the Indenture, upon the surrender of such bonds at the office or agency of the Company in the Borough of Manhattan, The City of New York. The Company covenants and agrees that, notwithstanding Section 2.03 of the Indenture, it will not charge any sum for or in connection with any exchange or transfer of any Senior Note Series F Bond.

     Section 2.09 Senior Note Series F Bonds as ‘Related Senior Note First Mortgage Bonds’. For purposes of Section 4.07 of the Senior Note Indenture, each Senior Note Series F Bond shall be deemed to be the “Related Senior Note First Mortgage Bond” in respect of the New Senior Notes issued concurrently therewith and referred to in the form of such Senior Note Series F Bond.

At any time a New Senior Note shall cease to be entitled to any lien, benefit or security under the Senior Note Indenture pursuant to Section 5.01(b) thereof and the Company shall have provided the Senior Note Trustee with notice thereof, the Senior Note Trustee shall surrender an equal principal amount of the Related Senior Note First Mortgage Bonds, subject to the limitations of Section 4.06 of the Senior Note Indenture, to the Company for cancellation.

The Trustee may at anytime and all times conclusively assume that the obligation of the Company to make payments with respect to the principal of and premium, if any, and interest on any Senior Note Series F Bond, so far as such payments at the time have become due, has been fully satisfied and discharged pursuant to the foregoing sentence unless and until the Trustee shall have received a written notice from the Senior Note Trustee signed by one of its officers stating (i) that timely payment of principal of, or premium or interest on, the New Senior Notes referred to above has not been made, (ii) that the Company is in arrears as to the payments required to be made by it to the Senior Note Trustee pursuant to the Senior Note Indenture, and (iii) the amount of the arrearage.

     For purposes of Section 4.07 of the Senior Note Indenture, this bond shall be deemed to be the “Related Senior Note First Mortgage Bonds” in respect of the New Senior Notes issued concurrently therewith and referred to above.

     The Mortgage contains provisions permitting the holders of not less than seventy-five per centum (75%) in principal amount of all the bonds at the time outstanding, determined and evidenced as provided in the Mortgage, or in case the rights under the Mortgage of the holders of bonds of one or more, but less than all, of the series of bonds outstanding shall be affected, the holders of not less than seventy-five per centum (75%) in principal amount of the outstanding bonds of such one or more series affected, except that if any such action would affect the bonds of two or more series, the holders of not less than seventy-five per centum (75%) in principal amount of outstanding bonds of such two or more series, which need not include seventy-five per centum (75%) in principal amount of outstanding bonds of each of such series, determined and evidenced as provided in the Mortgage, on behalf of the holders of all the bonds, to waive any past default under the Mortgage and its consequences except a completed default, as defined in the Mortgage, in respect of the payment of the principal of or interest on any bond or except a default arising from the creation of any lien ranking prior to or equal with the lien of the Mortgage on any of the mortgaged property, subject to the condition that, in case the rights of the holders of less than all of the series of bonds outstanding shall be affected, no waiver of any past default or its consequences shall be effective unless approved by the holders of not less than a majority of all the bonds at the time outstanding. The Mortgage also contains provisions permitting the Company and the Trustee, with the consent of the holders of not less than seventy-five per centum (75%) in principal amount of all the bonds at the time outstanding, determined and evidenced as provided in the Mortgage, or in case the rights under the Mortgage of the holders of bonds of one or more, but less than all, of the series of bonds outstanding shall be affected, then with the consent of the holders of not less than seventy-five per centum (75%) in principal amount of the outstanding bonds of such one or more series affected,

Any such waiver or consent by the holder of this bond (unless effectively revoked as provided in the Mortgage) shall be conclusive and binding upon such holder and upon all future holders of this bond, irrespective of whether or not any notation of such waiver or consent is made upon this bond.

     No reference herein to the Mortgage and no provision of this bond or of the Mortgage shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this bond at the time and place and at the rate and in the coin or currency herein prescribed.

     Senior Note Series F Bonds shall not be redeemed except as set forth below and except by the surrender thereof by the Senior Note Trustee to the Trustee for cancellation at a redemption price of zero upon redemption of all other series of bonds pursuant to Section 8.08 of the Mortgage. In the event the Company redeems any New Senior Notes referred to above prior to maturity in accordance with the provisions of the Senior Note Indenture, the Senior Note Trustee shall on the same date deliver to the Company this Senior Note Series F Bond for cancellation of a principal amount thereof corresponding to the New Senior Notes so redeemed, as provided in Section 4.06 of the Senior Note Indenture. Senior Note Series F Bonds are not redeemable by the operation of the improvement fund pursuant to Section 5.22 and Section 9.06 of the Indenture or otherwise or by operation of the maintenance and replacement provisions of Section 5.07 and Section 9.06 of the Indenture or otherwise or with the proceeds of released property pursuant to Section 9.06 of the Indenture or otherwise.

     The Senior Note Series F Bonds shall be immediately redeemed at a redemption price of 100% of the principal amount thereof, plus interest accrued to the redemption

date, in whole, upon a written demand for redemption by the Senior Note Trustee stating that the principal of all Senior Notes then outstanding under the Senior Note Indenture have been declared to be immediately due and payable pursuant to the provisions of the first sentence of Section 8.01(a) thereof.

     The Mortgage provides that if the Company shall deposit with the Trustee in trust for the purpose funds sufficient to pay the principal of all of the bonds of any series, or such of the bonds of any series as have been or are to be called for redemption, and premium, if any, thereon, and all interest payable on such bonds to the date on which they become due and payable, at maturity or upon redemption or otherwise, and complies with the other provisions of the Mortgage in respect thereof, then from the date of such deposit such bonds shall no longer be secured by the lien of the Mortgage.

     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 not transferable except (i) as required to effect an assignment to a successor Trustee under the Senior Note Indenture, (ii) pursuant to Section 4.03 or Section 4.06 of the Senior Note Indenture, or (iii) in compliance with a final order of a court of competent jurisdiction in connection with any bankruptcy or reorganization proceeding of the Company. This bond shall be exchangeable for other registered bonds of the same series and for the same aggregate principal amount, in the manner and upon the conditions prescribed in the Mortgage, upon the surrender of such bonds at the office or agency of the Company in the Borough of Manhattan, The City of New York. However, notwithstanding the provisions of Section 2.03 of the Mortgage, no charge shall be made upon any registration of transfer or exchange of bonds of said series. The Company and the Trustee, any paying agent and any bond registrar may deem and treat the person in whose name this bond is registered as the absolute owner hereof, whether or not this bond shall be overdue, for the purpose of receiving payment and for all other purposes and neither the Company nor the Trustee nor any paying agent nor any bond registrar shall be affected by any notice to the contrary.

     No recourse under or upon any obligation, covenant or agreement contained in the Mortgage, or in any bond or coupon thereby secured, or because of any indebtedness thereby secured, shall be had against any incorporator, or against 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 by any legal or equitable proceeding or otherwise; it being expressly agreed and understood that the Mortgage, and the obligations thereby secured, are solely corporate obligations, and that no personal liability whatever shall attach to, or be incurred by, such incorporators, stockholders, officers or directors, as such, of the Company or of any successor corporation, or any of them because of the incurring of the indebtedness thereby authorized or under or by reason of any of the obligations, covenants or agreements contained in the Mortgage or in any of the bonds or coupons thereby secured, or implied therefrom.
