Such awards have no vesting requirements and are treated as having “vested” upon grant for purposes of our Option Exercises and Stock Vested table. Accordingly, we have determined that for purposes of calculating equity award adjustments above, the equity awards made pursuant to the Stock Bonus Plan shall be deemed to have been granted and vested in the same year

(9) Change in Pre-tax Net Income (Loss) is defined as the change in net income or (loss) before income tax provision in the current year compared to net income or (loss) for the immediately preceding year.
