Stock-Based Compensation | 9. Stock-Based Compensation Under the 2003 Plan, as restated in June 2011, the Company was authorized to issue options covering up to 3,500,000 common stock shares. Effective June 1, 2011, the Company adopted the 2011 Equity Incentive Plan (the 2011 Plan). The maximum number of shares with respect to which options may be granted under the 2011 Plan is 6,000,000 shares, which is offset and reduced by options previously granted under the 2003 Plan. The option price is determined by the Board of Directors but cannot be less than the fair value of the shares at the grant date. Generally, the options vest ratably over either four or five years and expire ten years from the grant date. Both plans provide for accelerated vesting if there is a change of control, as defined in the plans.
