Optional Interest Deferral

So long as no event of default (as defined in the Preliminary Prospectus Supplement) with respect to the notes has occurred and is continuing, the Company may, at its option, defer interest payments on the notes, from time to time, for one or more Optional Deferral Periods (as defined in the Preliminary Prospectus Supplement) of up to 20 consecutive Interest Payment Periods (as defined in the Preliminary Prospectus Supplement) each, except that no such Optional Deferral Period may extend beyond the final maturity date of the notes or end on a day other than the day immediately preceding an interest payment date.

Cumulative Deferral of Interest Payment

During any Optional Deferral Period, interest on the notes will continue to accrue at the then-applicable interest rate on the notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the notes). In addition, during any Optional Deferral Period interest on the deferred interest(“compound interest”) will accrue at the then-applicable interest rate on the notes (as reset from time to time on any Reset Date occurring during such Optional Deferral Period in accordance with the terms of the notes), compounded semi-annually, to the extent permitted by applicable law.

No interest will be due or payable on the notes during an Optional Deferral Period, except upon a redemption of any notes on any redemption date during such Optional Deferral Period (in which case all accrued and unpaid interest (including, to the extent permitted by applicable law, any compound interest) on the notes to be redeemed to, but excluding, such redemption date will be due and payable on such redemption date), or unless the principal of and interest on the notes shall have been declared due and payable as the result of an event of default with respect to the notes (in which case all accrued and unpaid interest, including, to the extent permitted by applicable law, any compound interest, on the notes shall become due and payable).

Before the end of any Optional Deferral Period that is shorter than 20 consecutive Interest Payment Periods, the Company may elect, at its option, to extend such Optional Deferral Period, so long as the entire Optional Deferral Period does not exceed 20 consecutive Interest Payment Periods or extend beyond the final maturity date of the notes. The Company may also elect, at its option, to shorten the length of any Optional Deferral Period. The Company cannot begin a new Optional Deferral Period until it has paid all accrued and unpaid interest(including, without limitation and to the extent permitted by applicable law, any compound interest) on the notes from any previous Optional Deferral Period.
