Effective January 24, 2017, Independent Bank Corporation amended its Amended and Restated Bylaws to change the vote threshold required for the election of directors.  Previously, a plurality of the votes cast was required regardless of whether the election was contested or non-contested.  Pursuant to the amendment effected on January 24, 2017, the applicable vote threshold depends on whether the election is contested or non-contested. In a non-contested election, a majority of the votes cast is required for the election of a director and, if an incumbent director fails to receive the required majority of the votes cast, the director is required to tender his or her resignation to the Board, which will ultimately make the decision whether or not to accept or reject the resignation after receiving the recommendation of the Nominating and Corporate Governance Committee. In a contested election, the vote threshold remains a plurality of the votes cast. An election shall be considered contested if there are more nominees for election than positions on the Board of Directors to be filled by election at that meeting.
