VeriSign (VRSN)

Stock Option Acceleration

On December 29, 2005, VeriSign’s Board of Directors approved the acceleration of the vesting of unvested and “out-of-the-money” stock options that had an exercise price per share in excess of $24.99, all of which were previously granted under VeriSign’s stock option plans and that were outstanding on December 29, 2005. Options to purchase approximately 8.8 million shares of common stock or 47% of the total outstanding unvested options on December 29, 2005 were subject to the acceleration. The options accelerated included certain options previously granted to executive officers and directors of VeriSign.

The acceleration was accompanied by restrictions imposed on any shares purchased through the exercise of accelerated options. Those restrictions will prevent the sale of any such shares prior to the date such shares would have originally vested had the optionee been employed on such date (whether or not the optionee is actually an employee at that time).

The purpose of the accelerated vesting was to enable the Company to reduce compensation expense associated with these options in future periods, beginning with the first quarter of 2006, in its consolidated financial statements, pursuant to SFAS 123R. The acceleration of the vesting of these options did not result in a charge to expenses in 2005. At the time of the acceleration, VeriSign estimated that the acceleration reduced stock-based compensation expense it otherwise would have been required to record by approximately $27.7 million in 2006.
