Interest payments for this Global Security shall be computed and paid on the basis of a 360-day year of twelve 30-day months.  If any Interest Payment Date or date on which the principal of this Global Security is required to be paid is not a Business Day, then payment of principal, premium or interest 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 such Interest Payment Date or date on which the principal of this Global Security is required to be paid and, in the case of timely payment thereof, no interest shall accrue for the period from and after such Interest Payment Date or the date on which the principal of this Global Security is required to be paid.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modifications of the rights and obligations of the Company and the rights of the Security holders 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 Securities.  Any such consent or waiver by the Holder of this Global Security shall be conclusive and binding upon such Holder and upon all future Holders of this Global Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu thereof whether or not notation of such consent or waiver is made upon the Security.
As set forth in and subject to the provisions of the Indenture, no Holder of any Securities will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to such Securities, the Holders of not less than a majority in principal amount of the outstanding Securities affected by such Event of Default shall have made written request and offered reasonable indemnity to the Trustee to institute such proceeding as Trustee and the Trustee shall have failed to institute such proceeding within 60 days; provided that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of and any premium or interest on this Security on or after the respective due dates expressed here.
No reference herein to the Indenture and to provisions of this Global Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and any premium and interest on this Global Security at the times, places and rates and the coin or currency prescribed in the Indenture.
As provided in the Indenture and subject to certain limitations therein set forth, this Global Security may be transferred only as permitted by the legend hereto.
If at any time the Depositary for this Global Security notifies the Company that it is unwilling or unable to continue as Depositary for this Global Security or if at any time the Depositary for this Global Security shall no longer be eligible 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 Security.  If a successor Depositary for this Global Security is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, the Company’s election to issue this Security in global form shall no longer be effective with respect to this Global Security and the Company will execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for this Global Security, will authenticate and deliver individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of this Global Security.

In such event, the Company shall execute, and the Trustee, upon receipt of a Company Order for the authentication and delivery of individual Securities of this Series in exchange for such Global Security, shall authenticate and deliver, individual Securities of this Series of like tenor and terms in definitive form in an aggregate principal amount equal to the principal amount of such Global Security or Securities in exchange for such Global Security or Securities.
Under certain circumstances specified in the Indenture, the Depositary may be required to surrender any two or more Global Securities which have identical terms (but which may have differing Original Issue Dates) to the Trustee, and the Company shall execute and the Trustee shall authenticate and deliver to, or at the direction of, the Depositary a Global Security in principal amount equal to the aggregate principal amount of, and with all terms identical to, the Global Securities surrendered thereto and that shall indicate all Original Issue Dates and the principal amount applicable to each such Original Issue Date.
