On March 17, 2014, the Board of Directors of NetSuite Inc. (the “Company”) approved an amendment to Article II, Section 2.9 of the Company’s Bylaws to adopt a majority vote standard in uncontested director elections. The new majority vote standard provides that to be elected, in an uncontested election, a director nominee must receive a majority of the votes cast such that the number of votes “for” the nominee exceeds the number of votes “against” the nominee. A plurality vote standard will be retained for the election of directors only in the event of a contested election.

The Amended and Restated Bylaws are effective March 17, 2014 and are attached as Exhibit 3.1 to this Report.

In addition to the amendment of the Company’s Bylaws, the Board also approved an amendment to the Company’s Corporate Governance Guidelines that requires any incumbent director who is not elected to the Board in an uncontested election (because the number of votes “for” the nominee does not exceed the number of votes “against” the nominee) to promptly tender his or her resignation to the Board.

The text of the Corporate Governance Guidelines amendment states:

If no stockholder has provided the Company notice of an intention to nominate one or more candidates to compete with the Board’s nominees in a director election at a stockholder meeting, or if the stockholders have withdrawn all such nominations by the date that is ten (10) calendar days in advance of the date the Company files its definitive proxy statement (regardless of whether thereafter revised or supplemented) for such meeting with the Securities and Exchange Commission (in either event, an “Uncontested Election”), then a nominee in such Uncontested Election must receive more votes cast for than against his or her election or re-election in order to be elected or re-elected to the Board. If a stockholder has provided the Company notice of an intention to nominate one or more candidates to compete with the Board’s nominees in a director election at a stockholder meeting and such stockholder has not withdrawn all such nominations by the date that is ten (10) calendar days in advance of the date the Company files its definitive proxy statement (regardless of whether thereafter revised or supplemented) for such meeting with the Securities and Exchange Commission, then the directors at such meeting shall be elected by a plurality of the votes cast at such meeting.

If an incumbent director fails to receive the required vote for re-election in an Uncontested Election, then such incumbent director shall immediately tender his or her resignation to the Board, and the Nominating and Governance Committee will act on an expedited basis to determine whether to accept such director’s resignation and will submit a recommendation for prompt consideration by the Board. The Board expects the director whose resignation is under consideration to abstain from participating in any decision regarding that resignation. The Nominating and Governance Committee and the Board may consider any factors they deem relevant in deciding whether to accept a director’s resignation. The Board’s explanation of its decision shall be promptly disclosed on a Form 8-K filed with the Securities and Exchange Commission.
