Stock Option Grants
The following table sets forth grants of stock options to acquire shares of our common stock made during the year ended December 31, 2005 to the named executive officers. We do not currently have (and have not previously had) any plan pursuant to which any stock appreciation rights may be granted.
The options vested in full on February 23, 2005, the date of grant.
Potential realizable value is based on the assumption that the common stock price appreciates at the annual rate shown, compounded annually, from the date of grant until the end of the option term. The amounts have been calculated based on the assumed appreciation rates shown in the table, assuming a per share market price equal to the market price on the date of grant. The actual value, if any, the named executive officer may realize will depend on the excess of the stock price over the exercise price on the date the option is exercised, if the
executive were to sell the shares on the date of exercise, so there is no assurance that the value realized will be equal to or near the potential realizable value as calculated in this table.
