Stock Option Plan Description | The Company adopted a stock option plan in October 2003 (the 2003 Plan). Under the plan, the Company granted options to purchase 242,000 shares (split-adjusted) to employees and directors, of which, options to purchase 187,000 shares (split-adjusted) have been exercised, options to purchase 45,000 shares (split-adjusted) have been forfeited, and 10,000 remain outstanding. Under the 2003 Plan, exercised options may be issued from either authorized but unissued shares, or treasury shares.
