EXPLANATORY NOTE

This Amendment No. 1 amends the Firstbank Corporation Quarterly Report on Form 10-Q for the quarter ended June 30, 2009, filed on August 7, 2009 (the “Original Filing”). Part II Item 4 of the Original Filing is being amended to include the results of the advisory vote on the executive compensation program. The Original Filing disclosed the results of the election of directors but inadvertently omitted the results of the advisory vote on executive compensation.

To comply with certain technical requirements of the SEC’s rules in connection with filing this amendment, we are including as exhibits current dated certifications of our principal executive officer and principal financial officer.

No other changes or updates are being made to the Original Filing. There are no changes to the financial results reported in the Original Filing.
