Explanation of Responses:
1. On June 30, 2008, Clyde Hosein was granted a performance-based option to purchase 200,000 common shares of Marvell Technology Group Ltd. (the "Company"). Performance is measured over six one-year performance periods based on the satisfaction of certain performance criteria. For the first five performance periods, 40,000 of the option shares plus any option shares that did not vest in a prior performance period will vest if the performance criteria are satisfied. In the sixth performance period, any option shares that did not vest in a prior performance period will vest if the performance criteria are satisfied. If at the end of the sixth and final performance period, any unvested performance-based stock options remain unvested as a result of not having met or exceeded the performance criteria during the final performance period then the remaining unvested options shall be cancelled.
2. The performance criteria for the third performance period was met, as determined by the Executive Compensation Committee on August 29, 2011, which will result in vesting of the option as to 40,000 common shares on September 8, 2011.
