Interest on this global Bond will be payable on the Interest Payment Date or Interest Payment Dates as specified on the face hereof and, in either case, at Maturity. Unless otherwise specified on the face hereof, payments on this global Bond with respect to any particular Interest Payment Date, redemption date or the Maturity Date will include interest accrued from and including the applicable Original Issue Date, or from and including the most recent Interest Payment Date to which interest has been paid or duly provided for, to but excluding the particular Interest Payment Date, redemption date or the Maturity Date. Interest on this global Bond will be computed and paid on the basis of a 360-day year of twelve 30-day months.

All percentages resulting from any calculation with respect to this global Bond will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point (with five one-millionths of a percentage point rounded upward) and all dollar amounts used in or resulting from any such calculation with respect to this global Bond will be rounded to the nearest cent (with one-half cent being rounded upward).

“Business Day” means, unless otherwise specified on the face hereof, any Monday, Tuesday, Wednesday, Thursday or Friday that in the City of New York, New York is not a day on which banking institutions are authorized or obligated by law or executive order to close. In any case when any Interest Payment Date, redemption date, or Maturity Date of any Bond shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of the Indenture or of the Bonds) payment of interest or principal (and premium, if any) need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on the Interest Payment Date, redemption date or at the Maturity Date, provided that no interest shall accrue for the period from and after such Interest Payment Date, redemption date or Maturity Date, as the case may be.

This global Bond is secured under the Company’s Mortgage, Security Agreement, Fixture Filing and Financing Statement between the Company and The Bank of New York Mellon Trust Company, N.A., as amended and supplemented from time to time (the “Mortgage”). Reference is made to the Mortgage for a description of the property mortgaged and pledged and the nature and extent of the security and to the Intercreditor and Collateral Trust Agreement among the Company, the Trustee and The Bank of New York Mellon Trust

Company, N.A., as collateral trustee, and the Indenture for the rights of the holders of the Bonds and of the Trustee in respect thereof. Reference is made to the Indenture and the Mortgage for the terms and conditions upon which the Bonds are secured and the circumstances under which additional bonds may be issued.

This global Bond will be subject to redemption at the option of the Company on any date in whole or from time to time in part in increments of $2,000 or integral multiples of $1,000 in excess thereof, at the redemption prices specified in an annex attached to this global Bond, plus accrued interest on the principal amount thereof to be redeemed to the redemption date, but payments due with respect to this global Bond prior to the redemption date will be paid to the Person in whose name this global Bond is registered at the close of business on the relevant Record Date specified on the face hereof, all as provided in the Indenture. The Company may exercise such option by causing the Trustee to transmit a notice of such redemption, not less than 30 nor more than 60 days prior to the redemption date, in accordance with the provisions of the Indenture. In the event of redemption of this global Bond in part only, this global Bond will be cancelled and a new global Bond representing the unredeemed portion hereof will be issued in the name of the Holder hereof. This global Bond is not subject to a sinking fund.

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 to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Bonds of all series that would be affected thereby. The Indenture also provides that the Holders of not less than a majority in principal amount of the Outstanding Bonds of all affected series may on behalf of the Holders of all Bonds of such series waive certain existing Events of Default and their consequences. Any such consent or waiver of the Holder of any Bond shall bind every future Holder of the same Bond and the Holder of every Bond issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Bond.

As set forth in, and subject to, the provisions and limitations set forth in the Indenture, the Holders of at least a majority in principal amount of the Outstanding Bonds of all series shall have any right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee.

If at any time the Depositary for this global Bond notifies the Company that it is unwilling or unable to continue as Depositary for this global Bond or if at any time the Depositary for this global Bond shall no longer be registered or in good standing under the Securities Exchange Act of 1934, as amended, or other applicable statute or regulation, the Company shall appoint a successor Depositary with respect to this global Bond. If a successor Depositary for this global Bond is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such condition, the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Bonds of this series, shall authenticate and deliver Bonds of this series in definitive form in an aggregate principal amount equal to the principal amount of this global Bond in exchange for this global Bond.

The Company may at any time and in its sole discretion and subject to the procedures of the Depositary determine that the Bonds of this series shall no longer be represented by a global Bond. In such event the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of definitive Bonds of this series, shall authenticate and deliver, Bonds of this series in definitive registered form without coupons, in any authorized denominations, in an aggregate principal amount equal to the principal amount of this global Bond, in exchange for this global Bond.

OPTIONAL REDEMPTION PROVISIONS

The Bonds will be redeemable, in whole or in part, at the Company’s option at any time or from time to time prior to maturity. Prior to January 15, 2049 (the “2049 Par Call Date”), the Bonds will be redeemable, in whole at any time or in part from time to time, at a redemption price equal to the greater of (i) 100% of the principal amount of the Bonds being redeemed and (ii) as determined by the Quotation Agent, the sum of the present values of the remaining scheduled payments of principal and interest on the Bonds being redeemed that would be due if the Maturity Date of such Bonds were the 2049 Par Call Date (not including any portion of any payments of interest accrued to, but not including, the redemption date), 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 20 basis points (the “2049 Make-Whole Amount”); plus, in either case, accrued and unpaid interest on the principal amount of the Bonds being redeemed to the redemption date.

On or after the 2049 Par Call Date, the Bonds will be redeemable at a redemption price equal to 100% of the principal amount of the Bonds being redeemed, plus accrued and unpaid interest on the principal amount of the Bonds being redeemed to the redemption date.

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Bonds to be redeemed (assuming that the Bonds matured on the 2049 Par Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Bonds.

“Independent Investment Banker” means an investment banking institution of international standing appointed by the Company.
