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 common stock and options to purchase common stock granted under the Plan have vesting periods of three years and options are exercisable for two years once fully vested. Some awards of stock have performance criteria as an additional condition of vesting. 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. Under the Plan, the total number of options permitted is 15 percent of issued and outstanding common shares.
