Macatawa Bank Corporation Announces Stock Repurchase Program

Holland, Michigan, May 17, 2007 – Macatawa Bank Corp. (NASDAQ: MCBC), parent company of Macatawa Bank, today announced a stock repurchase program under which the Corporation may acquire up to $30,000,000 of its outstanding common stock.

Macatawa Bank Corporation Chairman and CEO Benj. A. Smith III said “The Board considers the Corporation’s common stock to be an attractive investment, given the price range in which it has traded recently.” Smith characterized the stock repurchase program as “part of Macatawa Bank Corporation’s ongoing efforts to enhance shareholder value and invest our resources in the most efficient manner possible.”

According to Smith, the repurchases generally will be effected through open market purchases, although he did not rule out the possibility of unsolicited negotiated transactions or other types of repurchases. Share repurchases will be funded from available cash, under existing lines of credit and additional credit arrangements to be negotiated. “The extent of the repurchase program will depend on availability of funds, market conditions, share price, trading volumes and other factors,” Smith said, “and the exact number of shares the Corporation will repurchase is not guaranteed.” The Board of Directors may modify, suspend, extend or terminate the program at any time.
