Employee Stock Ownership Plan (ESOP), Plan Description					The Compensation Committee administers the stock-based plans. The exercise price for Incentive Stock Options (ISO) cannot be less than the fair value of the stock subject to the option on the grant date (110% of such fair value in the case of ISOs granted to a stockholder who owns more than 10% of the Companys Common Stock). The exercise price of a Non-Qualified Stock Options (NQSO) shall be fixed by the Compensation Committee at whatever price the Committee may determine in good faith. Unless the Committee determines otherwise, options beginning with the 2007 Plan generally have a 4-year term with a 3-year vesting schedule.
