Summary of Option Activity Under Stock Option Plans

Stock options may be granted as incentive or nonqualified options; however, no incentive stock options have been granted to date. The exercise price of options is at least equal to the market price of the stock as of the date of grant. Options may vest over various periods but typically vest on a quarterly basis over three years. Options expire after five years, ten years or within a specified time from termination of employment, if earlier. The Company issues new shares of common stock upon the exercise of stock options.
