VeriSign (VRSN)

Stock Option Plans

The majority of VeriSign’s stock-based compensation expense relates to restricted stock units (“RSUs”) and stock options. Historically, stock options have been granted to broad groups of employees at most levels on a discretionary basis. In the second quarter of 2006, the Compensation Committee, in consultation with other members of the Company’s Board of Directors, resolved to grant RSUs instead of stock options to employees below the director level. Employees at or above the director level continue to be eligible to receive stock options as well as RSUs. As of December 31, 2007, a total of 33.2 million shares of common stock were reserved for issuance upon the exercise of stock options and for the future grant of stock options or awards under VeriSign’s equity incentive plans.

On May 26, 2006, the stockholders of VeriSign approved the 2006 Equity Incentive Plan (“2006 Plan”). The 2006 Plan replaces VeriSign’s 1998 Directors Plan, 1998 Equity Incentive Plan, and 2001 Stock Incentive Plan. The 2006 Plan authorizes the award of incentive stock options to employees and non-qualified stock options, restricted stock awards, restricted stock units, stock bonus awards, stock appreciation rights and performance shares to eligible employees, officers, directors, consultants, independent contractors and advisors. Options may be granted at an exercise price not less than 100% of the fair market value of VeriSign’s common stock on the date of grant. The 2006 Plan is administered by the Compensation Committee which may delegate to a committee of one or more members of VeriSign’s Board of Directors or VeriSign’s officers the ability to grant awards and take certain other actions with respect to participants who are not executive officers or non-employee directors. All options have a term of not greater than 10 years from the date of grant. Options issued generally vest 25% on the first anniversary date and ratably over the following 12 quarters. A restricted stock unit is an award covering a number of shares of VeriSign common stock that may be settled in cash or by issuance of those shares, which may consist of restricted stock. Restricted stock units generally vest in four installments with 25% of the shares vesting on each anniversary of the date of grant over 4 years. The Compensation Committee, however, may authorize grants with a different vesting schedule in the future. 27.0 million common shares were authorized and reserved for issuance under the 2006 Plan.

The 2001 Stock Incentive Plan (“2001 Plan”) was terminated upon approval of the 2006 Plan. Options to purchase common stock granted under the 2001 Plan remain outstanding and subject to the vesting and exercise terms of the original grant. The 2001 Plan authorized the award of non-qualified stock options and restricted stock awards to eligible employees, officers who are not subject to Section 16 reporting requirements, contractors and consultants. As of December 31, 2007, no restricted stock awards have been made under the 2001 Plan. Options were granted at an exercise price not less than 100% of the fair market value of VeriSign’s common stock on the date of grant. All options were granted at the discretion of the Board and have a term not greater than 10 years from the date of grant. Options issued generally vest 25% on the first anniversary date and ratably over the following 12 quarters. No further options can be granted under the 2001 Plan.

All shares that remained available for future issuance under the 1995 and 1997 Plans at the time of their termination were transferred to the 1998 Equity Incentive Plan. No further options can be granted under the 1995 and 1997 Plans. Options granted under the 1995 and 1997 Plans are subject to terms substantially similar to those described below with respect to options granted under the 1998 Equity Incentive Plan.

Stock Option Plans

As of March 31, 2006, a total of 55,179,165 shares of common stock were reserved for issuance upon the exercise of stock options and for the future grant of stock options or awards under VeriSign’s equity incentive plans.

The 1995 Stock Option Plan and the 1997 Stock Option Plan (“1995 and 1997 Plans”) were terminated concurrent with VeriSign’s initial public offering in 1998. Options to purchase common stock granted under the 1995 and 1997 Plans remain outstanding and subject to the vesting and exercise terms of the original grant. All shares that remained available for future issuance under the 1995 and 1997 Plans at the time of their termination were transferred to the 1998 Equity Incentive Plan. No further options can be granted under the 1995 and 1997 Plans. Options granted under the 1995 and 1997 Plans are subject to terms substantially similar to those described below with respect to options granted under the 1998 Equity Incentive Plan.

The 1998 Equity Incentive Plan (“1998 Plan”) authorizes the award of options, restricted stock awards, restricted stock units and stock bonuses. Options may be granted at an exercise price not less than 100% of the fair market value of VeriSign’s common stock on the date of grant for incentive stock options and 85% of the fair market value for non-qualified stock options. All options are granted at the discretion of the Board and have a term not greater than 7 years from the date of grant. Options issued generally vest 25% on the first anniversary date and ratably over the following 12 quarters. Restricted stock awards and restricted stock units entitle the recipient to receive, at VeriSign’s discretion, shares or cash upon vesting.

The 2001 Stock Incentive Plan (“2001 Plan”) authorizes the award of non-qualified stock options and restricted stock awards to eligible employees, officers who are not subject to Section 16 reporting requirements, contractors and consultants. As of December 31, 2005, no restricted stock awards have been made under the 2001 Plan. Options may be granted at an exercise price not less than the par value of VeriSign’s common stock on the date of grant. All options are granted at the discretion of the Board and have a term not greater than 10 years from the date of grant. Options issued generally vest 25% on the first anniversary date and ratably over the following 12 quarters. The 2001 Plan provides that on January 1 of each year beginning in 2002, the number of shares available for grant thereunder will automatically be increased by an amount equal to 2% of the outstanding common shares on the immediately preceding December 31.

Members of the Board who are not employees of VeriSign, or of any parent, subsidiary or affiliate of VeriSign, are eligible to participate in the 1998 Directors Plan (“Directors Plan”). The option grants under the Directors Plan are automatic and non-discretionary, and the exercise price of the options is 100% of the fair market value of the common stock on the date of the grant. Each eligible director is initially granted an option to purchase 25,000 shares on the date he or she first becomes a director (“Initial Grant”). On each anniversary of a director’s Initial Grant or most recent grant if he or she was ineligible to receive an Initial Grant, each eligible director will automatically be granted an additional option to purchase 12,500 shares of common stock if the director has served continuously as a director since the date of the Initial Grant or most recent grant. The term of the options under the Directors Plan is ten years and options vest as to 6.25% of the shares each quarter after the date of the grant, provided the optionee remains a director of VeriSign.

In connection with its acquisitions in 2005, VeriSign assumed some of the acquired companies’ stock options. Options assumed generally have terms of seven to ten years and generally vest over a four-year period.
