REVERSE OF BOND

          This Bond is one of an authorized issue of Bonds of the Company known as its “3.05% Collateral Trust Bonds due 2016”, issued and to be issued in one or more series under, and all equally and ratably secured (except as any sinking or other fund may afford additional special security for the Bonds of any particular series) by, an Indenture dated as of October 25, 2007 (as amended, supplemented and modified and in effect from time to time, the “Indenture”), executed by the Company to U.S. Bank National Association, as Trustee (herein called the “Trustee”, which term includes any successor Trustee under the Indenture), to which Indenture reference is hereby made for a description of the nature and extent of the securities and other property assigned, pledged, transferred and mortgaged thereunder the rights of the Holders of said Bonds and of the Trustee and of the Company in respect of such security, and the terms upon which said Bonds are to be authenticated and delivered.

          The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Bonds under the Indenture at any time by the Company with the consent of the Holders of not less than a majority in aggregate principal amount of the Bonds at the time Outstanding as defined in the Indenture. The Indenture also permits, without the consent of the holders of any Bonds, the parties to any Mortgage Notes pledged under the Indenture, and any Mortgages or Loan Agreements pursuant to which they were issued, to modify, alter, supplement or amend such Mortgage Notes, Mortgages and Loan Agreements, so long as thereafter such Mortgage will comply with the requirements of the Company’s standard lending practices, as such policies may be amended from time to time. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Bonds at the time Outstanding, on behalf of the Holders of all Bonds, to waive compliance by

the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Bond shall be binding upon such Holder and upon all future Holders of this Bond and of any Bond issued upon the transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such action is made upon this Bond.

          As provided in the Indenture, said Bonds are issuable in series which may vary as in said Indenture provided or permitted. This Bond is one of a series entitled 3.05% Collateral Trust Bonds due 2016.

          The Company may redeem the Bonds in whole or in part at any time, at a “make-whole” redemption price equal to the greater of (1) 100% of the principal amount being redeemed or (2) the sum of the present values of the remaining scheduled payments of the principal and interest (other than accrued interest) on the Bonds being redeemed, discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 10 basis points for the Bonds, plus in each of (1) and (2) above, accrued interest to the redemption date.

          If the Company elects to redeem less than all of the Bonds, and such Bonds are at the time represented by a global security, then the depositary will select by lot the particular interest to be redeemed. If the Company elects to redeem less than all of the Bonds, and such Bonds are not represented by a global security, the particular Bonds to be redeemed shall be selected by the Trustee from the outstanding Bonds not previously called for redemption, in a manner the Trustee deems appropriate and fair.

          Notice of any redemption will be mailed at least 30 days but not more than 60 days before the date of redemption to each holder of the Bonds to be redeemed. Unless the Company defaults in payment of the redemption price, on and after the date of redemption,

interest will cease to accrue on such Bonds or the portions called for redemption.

          If an Event of Default, as defined in the Indenture, shall occur, the principal of this Bond may become or be declared due and payable immediately, in the manner and with the effect provided in the Indenture.

          This Bond is transferable by the registered owner hereof in person or by attorney authorized in writing at the office or agency of the Company in the Borough of Manhattan, City and State of New York or any other place or places where such Bond may be paid, upon surrender of this Bond, and upon any such transfer a new Bond for the same series, for the same aggregate principal amount, will be issued to the transferee in exchange hereof.

          The Bonds of this series are issuable only as registered Bonds without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in, and subject to the provisions of, the Indenture, Bonds of this series are exchangeable for other Bonds of this series of any authorized denominations, of a like aggregate principal amount, as requested by the Holder surrendering the same.

          No service charge will be made for any such transfer or exchange, but the Company or the Trustee may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

          Prior to due presentment for transfer at any office or agency of the Company designated for such purpose, the Company, the Trustee and any agent of the Company or the Trustee may treat the person in whose name this Bond is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes whether or not this Bond be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

          No reference herein to the Indenture and no provision of this Bond or of the Indenture 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 times, place and rate, and in the coin or currency, herein prescribed.
