EXPLANATORY NOTE

          Macatawa Bank Corporation has completed its offering of shares of common stock in a rights offering and is now offering shares of its common stock in a public offering. The purchase price in the rights offering was, and the purchase price in the public offering is, $2.30 per share.

          This prospectus supplement reports the results of the rights offering, provides information about the public offering, including the number of shares the Board of Directors has determined are available for purchase in the public offering and what you must do to purchase shares of common stock allocated to you in the public offering, and updates or supplements certain information in the prospectus. Please refer to our prospectus for more information about our rights offering and the public offering.

          If you wish to purchase shares in the public offering, or if you wish to purchase more shares than have been allocated to you, please contact Jon W. Swets at jswets@macatawabank.com or (616) 494-7645 to determine if additional shares are available for purchase.

RESULTS OF THE RIGHTS OFFERING

          The rights offering expired at 5:00 p.m., Eastern Time, on June 7, 2011. In the rights offering, shareholders exercising their rights purchased a total of 4,456,186 shares of our common stock at a price of $2.30 per share, for an aggregate purchase price of approximately $10.2 million.

SHARES AVAILABLE IN THE PUBLIC OFFERING

          A total of 4,456,186 shares of our common stock are available for purchase in the public offering at a price of $2.30 per share.

          The total size of the offering, including the 4,456,186 shares sold in the rights offering and the 4,456,186 shares offered in the public offering, is 8,912,372 shares. If all 4,456,186 shares are sold in the public offering, the total gross proceeds to the Company from the rights offering and the public offering will be approximately $20.5 million.

          The original size of the offering, $41 million and 17,826,086 shares, was selected by the Board of Directors as the size required to be able to offer each existing shareholder the right to buy one share of common stock for each share of common stock owned on the record date in the rights offering at a price of $2.30 per share. The original offering size was in excess of the Company's current capital needs. The Board of Directors did not expect that all shareholders would exercise their rights to purchase shares in the rights offering and did expect that less than all shares offered would be sold in the rights offering.

          The current offering size was determined by the Board of Directors on June 16, 2011. At that time, the Board of Directors met and evaluated the following factors:

 

The successful sale of 4,456,186 shares in the rights offering, for an aggregate purchase price of approximately $10.2 million;

 

The number of written expressions of interest to participate in the public offering received to date;

 

The amount of additional capital required to comply with the Bank's consent order;

 

The amount of capital believed to be needed to fund organic growth of the Bank, provide the ability to absorb possible future losses, and meet the other capital needs of the Company and the Bank; and

 

Potential dilution to existing shareholders, including those who purchased shares in the rights offering, which could result from the sale of a larger number of shares.

          Based on these considerations, the Board of Directors selected a total offering size of $20.5 million, including the approximate $10.2 million of shares sold resulting from the successful completion of the rights offering. Accordingly, 4,456,186 additional shares are offered in the public offering.


2


          This offering size will permit the Company to allocate shares in the public offering to all potential investors who submitted a written expression of interest on or before June 7, 2011. It will also make shares available to additional interested investors who have not previously expressed an interest to participate in the public offering. If you wish to purchase shares in the public offering, but have not yet submitted to the Company a written expression of interest to participate in the public offering, please contact Jon W. Swets at jswets@macatawabank.com or (616) 494-7645.

          The Company reserves the right to allocate shares in the public offering and decline to sell shares to any potential investor in the public offering in its discretion and for any reason.

CAPITALIZATION

          The following table sets forth our consolidated capitalization as of March 31, 2011 and our pro forma consolidated capitalization after giving effect to the receipt of net proceeds from the offerings. The "Maximum Participation Scenario" includes 4,456,186 shares sold in the rights offering and assumes that all of the shares offered in the public offering are sold. The "Minimum Participation Scenario" includes 4,456,186 shares sold in the rights offering and assumes that 50% of the shares offered in the public offering are sold. We are unable to predict the actual level of participation in the public offering. There is no assurance that we will achieve the Maximum Participation Scenario.

          The following unaudited information should be read in conjunction with our unaudited consolidated financial statements for the three months ended March 31, 2011, and related notes, included in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2011, and our audited consolidated financial statements for the year ended December 31, 2010, and related notes, included in our Annual Report on Form 10-K for the year ended December 31, 2010, which reports are incorporated by reference into the prospectus.
