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 stated maturity 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 stated maturity, provided that no interest shall accrue for the period from and after such Interest Payment Date, Redemption Date or stated maturity, 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.

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 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 mail 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.

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 each 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, with respect to the Securities of such series.

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.
