The following table contains a list of your outstanding option grants that are eligible for exchange.

Value of the
Option Grant Number of Restricted
Stock Units You
Will Receive in Exchange for
the Option Grant

The number of restricted stock units you will receive in exchange for participating in this offer will equal the quotient of the Option Value (as calculated on September 12, 2006) divided by $19.20 (the closing price of our stock on September 12, 2006). For each eligible option, we will divide the Option Value by $19.20. That number (rounded up to the nearest whole number) will equal the number of restricted stock units you will receive in exchange for your cancelled options.

EXAMPLE
If you exchange 500 options with an Option Value of $2,500, you will receive 131 restricted stock units ($2,500 divided by $19.20 with the result rounded up to the nearest whole share).
