Section 5 – Corporate Governance and Management

2011 Employee and Executive Incentive Compensation Plan

On May 12, 2010, the compensation committee of our board of directors established the performance goals for our 2011 fiscal year (the “2011 Performance Goals”) under our Employee and Executive Incentive Compensation Plan (the “Bonus Plan”). The 2011 Performance Goals relate to revenue and non-GAAP operating income for our 2011 fiscal year, and are divided between the first two quarters of our 2011 fiscal year and the last two quarters of our 2011 fiscal year. The non-GAAP operating income goal excludes the impact of stock-based compensation expense and is calculated after giving effect to the accrual for the bonus payouts under the Bonus Plan.

Our executive officers, including our Chief Executive Officer, but excluding our Vice President of Worldwide Sales, may be eligible to receive a semi-annual cash bonus based on our achievement of certain performance objectives. The cash target bonus levels for our executive officers, including our Chief Executive Officer, are as follows:

30% of the bonus payout is based on the achievement of the 2011 Performance Goals in the first two quarters of our 2011 fiscal year, and 70% of the bonus payout is based on the achievement of the 2011 Performance Goals in the last two quarters of our 2011 fiscal year.

We intend to initially fund our Bonus Plan for our 2011 fiscal year with respect to our executive officers, other than our Chief Executive Officer, at 66.7%. In addition, while our Chief Executive Officer is entitled under his employment agreement to receive a bonus equal to 100% of his base salary, he has voluntarily reduced his bonus rate under our Bonus Plan for our 2011 fiscal year to 85%. Notwithstanding, the compensation committee maintains discretion to provide for bonus awards under our Bonus Plan in excess of the target base salary percentages if we exceed the 2011 Performance Goals, and awards will be reduced if we do not achieve the 2011 Performance Goals. In addition, if certain minimum performance targets are not achieved, no payouts will be made under the Bonus Plan for fiscal 2011. The compensation committee may, however, approve payments of bonuses outside the Bonus Plan, regardless of whether performance targets have been achieved.

Our Vice President of Worldwide Sales does not participate in the Bonus Plan. Instead, he receives sales commission in a manner similar to the commission-based compensation program for our sales group, which he heads.

2011 Base Salaries

In addition, on May 12, 2010, the compensation committee also approved an increase in the annual base salary for certain of our executive officers, including the following “named executive officers”:
