MERCANTILE BANK CORPORATION DECLARES
5% COMMON STOCK DIVIDEND

Grand Rapids, MI, April 11, 2007 — At a meeting held April 10, 2007, the Board of Directors of Mercantile Bank Corporation (Nasdaq: MBWM) declared a five percent stock dividend on the Corporation’s common stock. The dividend is payable on May 4, 2007 to shareholders of record as of the close of business on April 23, 2007. The stock dividend will increase shares outstanding by approximately 402,650 shares.

Gerald R. Johnson, Mercantile’s Chairman and CEO, stated, “In addition to the quarterly cash dividend we initiated in 2003, this represents the seventh annual stock dividend we declared. We believe that shareholders find both types of dividends attractive for very different reasons: stock dividends to increase overall liquidity and cash dividends to provide a current return. It is our intention to fulfill both of these objectives with our dividend strategy.”
