at such place and to such account at a banking institution in the United States as may be designated in writing to the Paying Agent at least ten (10) Business Days prior to the date for payment by the Person entitled thereto unless proper written transfer instructions have not been received by the relevant record date, in which case such payments shall be made by check mailed to the address of such Person as such address shall appear in the Security Register.

The Indenture also contains provisions permitting Holders of specified percentages in principal amount of the Securities, on behalf of the Holders of all Securities, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.

As provided in the Indenture and subject to certain limitations therein set forth, Securities are exchangeable for a like aggregate principal amount of Securities and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

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

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary.

The Company and, by its acceptance of this Security or a beneficial interest herein, the Holder of, and any Person that acquires a beneficial interest in, this Security agree that, for United States federal, state and local tax purposes, it is intended that this Security constitute indebtedness.

This Security shall be construed and enforced in accordance with and governed by the laws of the State of New York without reference to its conflict of laws provisions (other than Section 5-1401 of the General Obligations Law).
