6. Notice of Redemption. Notices of redemption shall be mailed by first class mail at least three but not more than 60 days before the Redemption Date to each Holder of 2016 Notes to be redeemed at its registered address.

7. Sinking Fund. There will be no mandatory sinking fund payment for the 2016 Notes.

8. [Deleted].

9. Denominations, Transfer, Exchange. The 2016 Notes are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000.

15. Defaults and Remedies. Events of Default are set forth in the Indenture. Subject to certain limitations in the Indenture, if an Event of Default with respect to 2016 Notes of this series occurs and is continuing, then, and in each and every such case, either the Trustee, by notice in writing to the Company, or the Holders of not less than 25% of the principal amount of the 2016 Notes then outstanding, by notice in writing to the Company and the Trustee, may, and the Trustee at the request of such Holders shall, declare due and payable, if not already due and payable, the principal of and any accrued and unpaid interest on all of the 2016 Notes of this series; and upon any such declaration all such amounts upon such 2016 Notes shall become and be immediately due and payable, anything in the Indenture or in the 2016 Notes to the contrary notwithstanding. If an Event of Default specified in clause (5) or (6) of Section 501 of the Indenture occurs with respect to the Company, then the principal of and any accrued and unpaid interest on all of the 2016 Notes shall immediately become due and payable without any declaration or other act on the part of the Trustee or any Holder. Holders may not enforce the Indenture or the 2016 Notes except as provided in the Indenture. The Trustee may require reasonable indemnity satisfactory to it before it enforces the Indenture or the 2016 Notes. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding 2016 Notes may direct the Trustee in its exercise of any trust or power.
