[1] The number of restricted stock units reflects the application of the award multiplier as described above (1.8x or 2.0x depending on the grant date of the applicable award).
[2] Share numbers reflect actual shares subject to awarded restricted stock units. As described above, under the terms of the 2004 Plan, the number of shares subject to each award reflected in this number is multiplied by either 1.8x or 2.0x (depending on the grant date of the award) to calculate the impact of the award on the share reserve under the 2004 Plan.
