Interest Rate

General

A glossary is provided at the end of this term sheet which defines the capitalized words used in the following discussion about the interest rates payable and optional redemption provisions on these notes.

Fixed Rate Notes

The interest rate on these notes will be fixed. Interest will be paid March 15 and September 15, and upon maturity, redemption or repurchase. The record dates for such notes will be March 1 (for interest to be paid on March 15) and September 1 (for interest to be paid on September 15). Interest payments will be the amount of interest accrued from and including the immediately preceding interest payment date in respect of which interest has been paid or from and including the date of issue, if no interest has been paid with respect to the notes, to, but excluding, each March 15 and September 15. Interest will be computed using a 360-day year of twelve 30-day months. If any interest payment date, redemption date, or the maturity date of the notes falls on a day that is not a Business Day, any principal, premium, or interest payments will be made on the next succeeding Business Day, and no interest will accrue on the amount payable for the period from and after the interest payment date, redemption date, or the maturity date, as the case may be.

Optional Redemption

The notes will not be subject to any sinking fund. The notes will be subject to redemption at our option on any date or dates on and after December 3, 2010, in whole or from time to time in part, in increments of $1,000. The redemption price, to be calculated by us, may be determined as the greater of (i) 100% of the principal of such notes; or (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon (exclusive of interest accrued to the date of redemption) discounted to the redemption date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below) plus a make-whole spread as specified in this term sheet (the Make-Whole Call Premium); plus accrued and unpaid interest thereon to the date of redemption. Notwithstanding the foregoing, installments of interest on notes that are due and payable on interest payment dates falling on or prior to a redemption date will be payable on the interest date to the registered holders as of the close of business on the relevant record date according to the notes and the indenture.

Notes may be redeemed in whole or in part in increments of $1,000, upon no more than 60 and not less than 30 days prior notice to the note holder. If we do not redeem all the notes of a series or tranche at one time, the Trustee will select the notes to be redeemed by lot, pro rata. Unless we default in payment of the redemption price, on and after the redemption date interest will cease to accrue on the notes or portions thereof called for redemption.
