Explanation of Responses:
1. On April 12, 2010, Ms. Weili Dai was granted a performance-based restricted stock unit ("RSU") award for up to 236,518 common shares, subject to the achievement of certain performance criteria (the "Grant"). A portion of the performance criteria were met, as determined per the administrator on March 14, 2012, and 151,690 common shares will vest and be issuable on April 1, 2012, subject to Ms. Dai's continuous status as a service provider through such date. The Grant automatically expired with respect to the 84,828 common shares that did not vest.
2. The securities are jointly owned by Ms. Dai and Dr. Sehat Sutardja who are members of a "Group" for purposes of Section 13(d) of the Securities Exchange Act of 1934, as amended. Ms. Dai and Dr. Sutardja are wife and husband.
3. Ms. Dai and Dr. Sutardja are the general partners of The Sutardja Family Partners, a California family limited partnership.
