• Full, fair, accurate, timely and understandable disclosure in documents the Company files with, or submits to, the SEC and in all public communications made by the Company;

• Compliance with applicable governmental laws, rules and regulations; and

• Prompt internal reporting to designated persons of violations of the code.

          The Code of Ethics is applicable to all directors, officers and employees of the Company. It provides standards of conduct with respect to, among other things, financial controls and reporting, use of Company assets, conflicts of interest and improper benefits, and confidentiality of customer and Company information. It also provides that violations of the Code of Ethics, complaints regarding accounting, internal control or audit matters, or concerns regarding questionable financial or accounting matters should be reported to the director of internal audit and that persons who report such matters in good faith will not be retaliated against in the terms and conditions of his or her employment.

          The Code of Ethics is filed with this report as Exhibit 14.1, and is here incorporated by reference. The Code of Ethics is also available on the Company's website, www.macatawabank.com, under the "Investor Relations - Governance Documents" section.
