Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(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 first performance period were not met and the applicable shares that were subject to vesting in the first performance period were rolled over into the second performance period. The performance criteria for the second performance period were met, as determined by the Executive Compensation Committee on August 24, 2010, which will result in vesting of the option as to 80,000 common shares on September 9, 2010.
