Approval of Executive Performance Incentive Plan

At the 2015 Annual General Meeting of Shareholders of Marvell Technology Group Ltd. (“Marvell”) held on June 30, 2015 (the “Annual Meeting”), the shareholders approved the Marvell Executive Performance Incentive Plan (the “Incentive Plan”). Under the Incentive Plan, annual incentive awards made to certain senior executives of Marvell will qualify for a tax deduction as “performance-based compensation” pursuant to Section 162(m) of the Internal Revenue Code of 1986, as amended (“Section 162(m)”), assuming compliance with the terms of the Incentive Plan. The Incentive Plan became effective on April 16, 2015, subject to shareholder approval at the Annual Meeting, and will be in effect until the 2020 annual general meeting of shareholders. Eligible participants in the Incentive Plan will be selected by the Executive Compensation Committee (the “Compensation Committee”) of Marvell’s Board of Directors (the “Board”); however, Marvell anticipates that all of its named executive officers will participate in the Incentive Plan. The Compensation Committee has exclusive authority to administer the Incentive Plan.

The Compensation Committee adopted the Incentive Plan on April 16, 2015, subject to shareholder approval at the Annual Meeting. A copy of the Incentive Plan is attached to this report as Exhibit 10.1. The description of the Incentive Plan contained herein is qualified in its entirety by reference to the full text of the Incentive Plan. In addition, a more detailed description of the material features of the Incentive Plan is contained in Proposal No. 3 of the Proxy Statement prepared by Marvell in preparation for the Annual Meeting and filed with the U.S. Securities and Exchange Commission on May 19, 2015 (the “Proxy Statement”) and is incorporated herein by reference.

Approval of an Amendment to Marvell’s Amended and Restated 1995 Stock Option Plan

At the Annual Meeting, the shareholders also approved an amendment to Marvell’s Amended and Restated 1995 Stock Option Plan (the “1995 Plan”) to (i) approval of the material terms of the 1995 Plan as such term is used for purposes of Section 162(m); (ii) amend the 1995 Plan to expressly allow our non-employee directors, or “outside directors,” to receive all types of awards available under the 1995 Plan in addition to stock options; and (iii) place limitations on the maximum compensation payable to an outside director.

The Board through the Compensation Committee adopted the amendment to the 1995 Plan (the “2015 Amendment”) on April 16, 2015, subject to shareholder approval at the Annual Meeting. A copy of the 1995 Plan, as amended by the 2015 Amendment, is attached to this report as Exhibit 10.2. The description of the 2015 Amendment contained herein is qualified in its entirety by reference to the full text of the 1995 Plan, as amended by the 2015 Amendment. In addition, a more detailed description of the 2015 Amendment is contained in Proposal No. 4 of the Proxy Statement and is incorporated herein by reference.

At the Annual Meeting held on June 30, 2015, shareholders voted on the matters as set forth below. Each issued common share was entitled to one vote on the proposals voted on at the meeting.

With respect to the election of each director, an “abstain” vote had the same effect as an “against” vote.
