8. SHARE-BASED COMPENSATION

6 Months Ended

Jun. 30, 2012

NOTE 8: SHARE-BASED COMPENSATION

We have a share-based compensation plan, the “2003 Directors, Officers and Consultants Stock Option, Stock Warrant and Stock Award Plan” (the “Plan”). Awards of stock options and stock granted under the Plan have vesting periods of three years. Some awards of stock have performance criteria as an additional condition of vesting. Once vested, stock options may be exercised for up to five years. Share-based compensation expense related to awards is based on the fair value at the date of grant, and is recognized over the vesting periods, net of estimated forfeitures. The value of performance-based awards is recognized as expense only when it is considered probable that the performance criteria will be met.
