The outstanding balance of our convertible subordinated notes is as follows (in thousands):

3.25% Notes due September 2012		March 28, September 28	$	214,955	$	214,955

Our convertible subordinated 3.25% notes due September 28, 2012 (Notes) are unsecured and subordinated in right of payment to any future senior debt. The Notes are convertible at the option of the holder at any time on or prior to maturity into shares of our common stock. The Notes have a conversion rate of 46.4727 shares per $1,000 principal amount, which is equal to a conversion price of approximately $21.52 per share. Additionally, at any time prior to maturity, if a fundamental change as defined in the Notes agreement occurs, we may be required to pay a make-whole premium on notes converted in connection therewith by increasing the applicable conversion rate.

We may redeem the Notes in whole or in part for cash at a redemption price equal to 100% of the principal amount of the Notes plus any accrued but unpaid interest if the closing price of the common stock has exceeded 150% of the conversion price for at least 20 days in any consecutive 30 day trading period.
