Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

Effective February 20, 2014, Firstbank Corporation amended Article II, Section 2 of its bylaws. The amended bylaws state that "the annual meeting of shareholders for election of directors and for such other business as may properly come before the meeting shall be held at such date and time as shall be determined from time to time by the Board of Directors."

Article II, Section 2 of the bylaws previously stated that "The annual meeting of shareholders for election of directors and for such other business as may properly come before the meeting, commencing with the year 1985, shall be held on the fourth Monday of April, if not a legal holiday, and if a legal holiday, then on the next business day following, at 5:00 p.m., local time, or at such other date and time as shall be determined from time to time by the Board of Directors, unless such action is taken by written consent as provided in Article II, Section 12 of these Bylaws. If the annual meeting is not held on the date designated therefor, the Board shall cause the meeting to be held as soon thereafter as convenient."

A copy of the bylaw amendment is attached as Exhibit 3.1 to this Report and is incorporated herein by reference.

At this time the Board of Directors has not set a date for the 2014 annual meeting of shareholders. The annual shareholders meeting will not be held in April as in past years. In light of the pending merger with Mercantile Bank Corporation, Firstbank Corporation does not anticipate holding an annual shareholders prior to the completion of that merger.
