The preferred stock is currently convertible into common stock at a conversion price of $5.94 per share of common stock (equivalent to a conversion rate of 168.3502 shares of common stock for each share of preferred stock), representing an adjustment of the initial conversion price of $7.48 per share of common stock (or initial conversion rate of 133.6898 shares of common stock for each share of preferred stock) on account of our distribution of our shares of Agere Systems Inc. to our common shareowners in connection with our spin-off of Agere Systems Inc. and is subject to further adjustments as described in the accompanying prospectus.

(3) Based on the principal amount of convertible subordinated debentures originally issuable in exchange for the preferred stock, calculated by reference to the initial liquidation preference of the preferred stock of $1,000.00 per share. The principal amount is subject to increase as a result of increases in the liquidation preference of the preferred stock to reflect the accretion of unpaid dividends.
