Item 5.02. Departure of Directors or Certain Officers; Election of Directors;
Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
(d) On April 29, 2009, our Board of Directors increased the size of the Board of Directors from seven to eight directors and elected Dr. Paramesh Gopi as a director effective immediately. Dr. Gopi is currently our Senior Vice President and Chief Operating Officer and will succeed Kambiz Hooshmand as our President and Chief Executive Officer when he steps down in May 2009. We are not aware of any transaction requiring disclosure under Item 404(a) of Regulation S-K. Item 5.03. Amendments to Articles of Incorporation or Bylaws; Changes in Fiscal Year.
(a) On April 29, 2009, our Board of Directors amended certain provisions of our Bylaws effective immediately. The provisions in our Bylaws described below were changed as a result of the amendment.
1. Sections 2.3 and 2.4 of the Bylaws were amended to:
• Clarify the advance notice requirements and the stock ownership requirements for beneficial owners for a nomination for an election of directors by a stockholder at any annual meeting or any special meeting of stockholders at which directors are to be elected or for a proposal by a stockholder at any annual meeting;

• Change the deadlines for stockholder notice of any nomination or other business at an annual meeting of stockholders to not earlier than the 90th day and not later than the 60th day prior to the first anniversary of the preceding year's annual meeting (instead of not earlier than the 120th day and not later than the 90th day prior to such anniversary);

• Change the deadlines for stockholder notice of any nomination at a special meeting of stockholders at which directors are to be elected to not earlier than the 90th day and not later than the 60th day prior to the special meeting (instead of not earlier than the 120th day and not later than the 90th day prior to the special meeting);

• Require a stockholder proponent of a nomination or other business to disclose in the stockholder's advance notice additional information regarding ownership interest, including a description of any derivative or short positions and borrowed or loaned shares the stockholder has with respect to our common stock;

• Require a stockholder providing advance notice of a nomination or other business to update the information contained in the notice prior to the meeting; and

• Require a stockholder nominating a person for election as a director to include in the stockholder's advance notice certain biographical information about each nominee as well as a questionnaire completed by each nominee that requires the nominee to disclose any voting commitments the nominee may have with third parties and a commitment by the nominee to comply with our corporate governance standards and certain other policies and guidelines if elected.

2. Section 3.3 of the Bylaws was amended to require directors to be elected by a majority of the votes cast in any uncontested election of directors (i.e., an election in which the number of nominees does not exceed the number of directors to be elected). If the election of directors is a contested election, the nominees receiving a plurality of the votes cast will be elected. Previously all directors were elected by a plurality of the votes cast in any contested or uncontested election. In connection with the change to majority voting,
Section 2.3 of the Bylaws was amended to require stockholder nominees to make a written representation and agreement that, if elected, such person would tender prior to being nominated for re-election an irrevocable resignation that will be effective upon (i) the failure by such person to receive the required vote for re-election and (ii) the Board's acceptance of such resignation, in accordance with our Board Guidelines.
3. Sections 2.1, 2.2, 2.5, 2.7, 2.10, 3.7, 3.9, and 3.10 of the Bylaws were amended to provide expressly for electronic transmission or remote communication mechanisms.
4. Out-of-date information referencing the authorized number of directors at the time the Bylaws were first adopted was removed from Section 3.2.
