However, interest payable on the Maturity Date will be paid to the person to whom principal on the Note is paid. The amount of interest payable during the Fixed Rate Period will be computed and paid on the basis of a 360-day year of twelve 30-day months.

In the event the Put Notice is timely given, the Company shall repurchase the Notes at the Redemption Price on October 16, 2006.

If required by the Calculation Agent, each holder shall indicate its election to have the Calculation Agent deliver the Put Notice to the Company by delivering written notice of such election to the Calculation Agent by no later than 12:00 noon (New York time) on October 5, 2006.
