The Trustee

13 shall, within five (5) days after receiving such Redemption Demand, mail a copy thereof to the Company marked to indicate the date of its receipt by the Trustee. Promptly upon receipt by the Company of such copy of a Redemption Demand, the Company shall fix a date on which it will redeem the bonds of said series so demanded to be redeemed (hereinafter called the "Demand Redemption Date"). Notice of the date fixed as the Demand Redemption Date shall be mailed by the Company to the Trustee at least ten (10) days prior to such Demand Redemption Date. The date to be fixed by the Company as and for the Demand Redemption Date may be any date up to and including the earlier of (x) the 60th day after receipt by the Trustee of the Redemption Demand or (y) the maturity date of such bonds first occurring following the 20th day after the receipt by the Trustee of the Redemption Demand; provided, however, that if the Trustee shall not have received such notice fixing the Demand Redemption Date on or before the 10th day preceding the earlier of such dates, the Demand Redemption Date shall be deemed to be the earlier of such dates. The Trustee shall mail notice of the Demand Redemption Date (such notice being hereinafter called the "Demand Redemption Notice") to the Note Indenture Trustee not more than ten (10) nor less than five (5) days prior to the Demand Redemption Date. Each bond of 2006 Series A shall be redeemed by the Company on the Demand Redemption Date therefor upon surrender thereof by the Note Indenture Trustee to the Trustee at a redemption price equal to the principal amount thereof plus accrued interest thereon at the rate specified for such bond from the Initial Interest Accrual Date to the Demand Redemption Date plus an amount equal to the aggregate premium, if any, due and payable on such Demand Redemption Date on all Notes; provided, however, that in the event of a receipt by the Trustee of a notice that, pursuant to Section 602 of the Note Indenture, the Note Indenture Trustee has terminated proceedings to enforce any right under the Note Indenture, then any Redemption Demand shall thereby be rescinded by the Note Indenture Trustee, and no Demand Redemption Notice shall be given, or, if already given, shall be automatically annulled; but no such rescission or annulment shall extend to or affect any subsequent default or impair any right consequent thereon. Anything herein contained to the contrary notwithstanding, the Trustee is not authorized to take any action pursuant to a Redemption Demand and such Redemption Demand shall be of no force or effect, unless it is executed in the name of the Note Indenture Trustee by its President or one of its Vice Presidents.

This bond and all other bonds of said series are issued and to be issued under, and are all equally and ratably secured (except insofar as any sinking, amortization, improvement or analogous fund, established in accordance with the provisions of the Indenture hereinafter mentioned, may afford additional security for the bonds of any particular series and except as provided in Section 3 of Article VI of said Indenture) by an Indenture, dated as of October 1, 1924, duly executed by the Company to J.P. Morgan Trust Company, National Association, as successor Trustee, to which Indenture and all indentures supplemental thereto (including the Supplemental Indenture dated as of May 15, 2006) reference is hereby made for a description of the properties and franchises mortgaged and conveyed, the nature and extent of the security, the terms and conditions upon which the bonds are issued and under which additional bonds may be issued, and the rights of the holders of the bonds and of the Trustee in respect of such security (which Indenture and all indentures supplemental thereto, including the Supplemental Indenture dated as of May 15, 2006, are hereinafter collectively called the "Indenture").

16 As provided in the Indenture, 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 in said Indenture provided.

This bond is not assignable or transferable except as set forth under Section 405 of the Note Indenture or in the supplemental indenture relating to the

17 Notes, or, subject to compliance with applicable law, as may be involved in the course of the exercise of rights and remedies consequent upon an Event of Default under the Note Indenture. Any such transfer shall be made by the registered holder hereof, in person or by his attorney duly authorized in writing, on the books of the Company kept at its office or agency in the Borough of Manhattan, the City and State of New York, upon surrender and cancellation of this bond, and thereupon, a new registered bond of the same series of authorized denominations for a like aggregate principal amount will be issued to the transferee in exchange therefor, and this bond with others in like form may in like manner be exchanged for one or more new bonds of the same series of other authorized denominations, but of the same aggregate principal amount, all as provided and upon the terms and conditions set forth in the Indenture, and upon payment, in any event, of the charges prescribed in the Indenture. From and after the Release Date (as defined in the Note Indenture), the bonds of 2006 Series A shall be deemed fully paid, satisfied and discharged and the obligation of the Company thereunder shall be terminated. On the Release Date, the bonds of 2006 Series A shall be surrendered to and cancelled by the Trustee. The Company covenants and agrees that, prior to the Release Date, it will not take any action that would cause the outstanding principal amount of the bond of 2006 Series A to be less than the then outstanding principal amount of the Notes.
