Stock Appreciation Rights. The 2004 Plan authorizes the administrator to grant SARs that provide the recipient with the right to receive, upon exercise of the SAR, cash or, at the discretion of the administrator, shares of common stock or other securities, property, awards or consideration, or any combination of such. The amount that the recipient will receive upon exercise of the SAR will be based on the excess of the fair market value of one share of our common stock (or other securities or property) on the date of exercise (or, in the discretion of the administrator, at any time during a specified period before or after the date of exercise) over the grant price of the SAR, as determined by the administrator, provided that the price cannot be less than 100% of the fair market value of our common stock (or other securities or property) on the date on which the SAR is granted. SARs will become exercisable in accordance with terms and conditions as determined by the administrator. SARs may be granted in combination with an option grant or independently from an option grant.
