ANNEX A

ADDITIONAL TERMS

Interest Rates

     If the Calculation Agent has not given the Put Notice (as defined below), then during the period from and including October 15, 2007 to the Maturity Date (the “Fixed Rate Period”), the Notes will bear interest at a fixed rate calculated as described below (see “Reset of Interest Rate for Fixed Rate Period” below). Interest during the Fixed Rate Period will be payable semi-annually in arrears on each April 15 and October 15, commencing April 15, 2008 (each a “Fixed Rate Interest Payment Date”), to the person in whose name a Note is registered on the April 1 or October 1 (whether or not a Business Day) immediately preceding the applicable Fixed Rate Interest Payment Date. 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.

     The Calculation Agent has the right to require the Company to repurchase all (but not less than all) of the Notes on October 15, 2007 at a purchase price equal to 100% of the principal amount thereof, plus accrued but unpaid interest to but excluding October 15, 2007 (the “Redemption Price”), by delivering written notice thereof to the Company on behalf of all (but not fewer than all) holders of the Notes (the “Put Notice”). Such Put Notice shall be given no later than 9:00 a.m. (New York time) on October 9, 2007. The Calculation Agent shall give the Put Notice if the holders of a majority in principal amount of the Notes request the Calculation Agent to give the Put Notice, in which event the Put Notice shall be binding on all Noteholders; the Calculation Agent shall not give the Put Notice absent such request of the holders of a majority in principal amount of the Notes. In the event the Put Notice is timely given, the Company shall repurchase the Notes at the Redemption Price on October 15, 2007.

      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 4, 2007.
