I, Jon W. Swets, certify that:

| | 1.     I have reviewed this annual report on Form 10-K of Macatawa Bank Corporation;
| | ------------------------------------------------------------------------------------

| | 2.     Based on my knowledge, this annual report does not contain any untrue statement
          of material fact or omit to state a material fact necessary to make the
          statements made, in light of the circumstances under which such statements were
          made, not misleading with respect to the period covered by this report;
| | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 3.     Based on my knowledge, the financial statements, and other financial information
          included in this annual report, fairly present in all material respects the
          financial condition, results of operations and cash flows of the registrant as
          of, and for, the periods presented in this annual report.
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 4.     The registrants other certifying officers and I are responsible for
          establishing and maintaining disclosure controls and procedures (as defined in
          Exchange Act Rules 13a-15(e) and 15d-15(e) and internal control over financial
          reporting (as defined in Exchange Act Rules 13a-15f and 15d-15(f)) for the
          registrant and have:
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (a)     designed such disclosure controls and procedures, or caused such
disclosure                     controls and procedures to be designed to ensure that
material information                     relating to the registrant, including its
consolidated subsidiaries, is made                     known to us by others within those
entities, particularly during the period in                     which this annual report
is being prepared;
| | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b)     designed such internal control over financial reporting, or caused such
                    internal control over financial reporting to be designed under our
supervision,                     to provide reasonable assurance regarding the
reliability of financial reporting                     and the preparation of financial
statements for external purposes in accordance                     with generally
accepted accounting principles.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (c)     evaluated the effectiveness of the registrants disclosure
controls and                     procedures and presented in this report our conclusions
about the effectiveness                     of the disclosure controls and procedures, as
of the end of the period covered                     by this report based on such
evaluation; and
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (d)     disclosed in this report any change in the registrants
internal control                     over financial reporting that occurred during the
registrants most recent                     fiscal quarter that has materially
affected, or is reasonably liked to                     materially affect, the registrants
internal control over financial                     reporting.
| | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | 5.     The registrants other certifying officers and I have disclosed, based on
          our most recent evaluation of internal control over financial reporting, to the
          registrants auditors and the audit committee of registrants board
of           directors (or persons performing the equivalent functions):
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (a)     all significant deficiencies and material weaknesses in the design or operation
                    of internal control over financial reporting which are reasonably
likely to                     adversely affect the registrants ability to record,
process, summarize and                     report financial information; and
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

| | (b)     any fraud, whether or not material, that involves management or other employees
                    who have a significant role in the registrants internal
controls.
