Explanation of Responses:
1. Ms. Weili Dai and Dr. Sehat Sutardja are the general partners of The Sutardja Family Partners, a California family limited partnership.
2. These securities are jointly owned by Ms. Weili Dai and Dr. Sehat Sutardja who are members of a "group" for purposes Section 13(d) of the Securities Exchange Act of 1934, as amended.
3. Fully vested and exerciseable. This option is owned directly by Ms. Weili Dai and indirectly by her spouse, Dr. Sehat Sutardja.
4. Fully vested and exerciseable. Subject to the Reformation Agreement entered into between the Company and Ms. Dai, effective December 26, 2006, the effective date of this grant was changed to January 16, 2004, based upon the Company's internal review of its stock option practices. As a result, the exercise price of the grant was changed to the fair market value of the common stock of the Company on January 16, 2004, or $10.91. On May 6, 2007, 666,667 unvested options were cancelled as a result of Ms. Dai's termination of service as an executive officer of the Company. This option is owned directly by Ms. Weili Dai and indirectly by her spouse, Dr. Sehat Sutardja.
