REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

May 17, 2006

Audit Committee
Macatawa Bank 401(k) Plan
Holland, Michigan

We have audited the accompanying statements of net assets available for benefits of Macatawa Bank 401(k) Plan as of December 31, 2005 and 2004, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements and supplemental schedule are the responsibility of the Plan’s management. Our responsibility is to express an opinion on these financial statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for plan benefits of the Macatawa Bank 401(k) Plan as of December 31, 2005 and 2004, and the changes in net assets available for plan benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America.

Our audits were performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The December 31, 2005 supplemental schedule of assets (held at end of year) is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. This supplemental information is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic 2005 financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic 2005 financial statements taken as a whole.

MACATAWA BANK 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS


1.       DESCRIPTION OF THE PLAN AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  The following description of the Macatawa Bank 401(k) Plan (the “Plan”) provides only general information. Additional information about the Plan agreement is contained in the Plan agreement or the Summary Plan Description.

          Description of the Plan

  General

  The Plan is a defined contribution plan covering all employees of Macatawa Bank Corporation (“Plan Sponsor” or “Corporation”) who have attained the age of 21 or older. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

  Contributions

  Participants may contribute annual compensation, as defined in the Plan, up to the maximum amount allowed by the Internal Revenue Code. Participants who have attained age 50 before the Plan year are eligible to make catch-up contributions. Participants may also contribute amounts representing distributions from other qualified defined benefit or defined contribution plans. The Plan’s Sponsor contributes an amount equal to 100% of the first 3% and 50% of the second 3% of base compensation that a participant contributes to the Plan. Participants direct the investment of contributions into various investment options offered by the Plan. The Plan currently offers 17 mutual funds and Macatawa Bank Corporation common stock as investment options for participants. Contributions are subject to certain limitations.

  Participant Accounts

  Each participant’s account is credited with the participant’s contribution, the Plan Sponsor match, and an allocation of Plan earnings. Plan earnings are allocated based on the ratio of each participant’s account balance to the total account balance. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

  Vesting

  A participant is immediately vested in employee and employer matching contributions, plus actual earnings thereon.

MACATAWA BANK 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS


  Participant Loans

  Participant loans, although not permitted by the terms of the current Plan, result from participant rollovers from predecessor plans. Loan balances are secured by the balance in the participant’s account, have interest rates ranging from 5.75% to 6.00%, and expected maturities through March 2007. Principal and interest is paid ratably through payroll deductions.

  Payment of Benefits

  On termination of service due to death, disability or retirement, a participant may elect to receive a lump-sum amount equal to the value of his or her vested account as defined by the Plan agreement. For termination of service for other reasons, a participant may receive the value of the vested interest in his or her account as a lump-sum distribution.

  On occasion, corrective distributions are made to participants in order for the Plan to comply with Internal Revenue Code contribution limits. Such corrective contributions are included as a deduction from net assets in the statements of changes in net assets available for benefits.

  Administrative Expenses

  The Plan’s administrative expenses, including salaries, accounting, legal, recordkeeping, and trust services are paid by the Plan Sponsor and qualify as party-in-interest transactions, which are exempt from prohibited transaction rules.

  Summary of Significant Accounting Policies

  Basis of Accounting

  The financial statements of the Plan are prepared under the accrual method of accounting.

  Use of Estimates

  The preparation of financial statements in conformity with generally accepted accounting principles requires the Plan’s Advisory Committee to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

MACATAWA BANK 401(k) PLAN

NOTES TO FINANCIAL STATEMENTS


  Investment Valuation and Income Recognition

  Mutual funds and corporate stock are stated at fair value, based upon quoted market prices. Money market fund investments and participant loans are reported at cost, which approximates fair value.

  Unrealized appreciation in the aggregate fair value of investments represents the change in the difference between aggregate fair value and the cost of investments, including reinvestment of earnings. The realized gain or loss on sale of investments is the difference between the proceeds received and the average costs of investments sold.

  Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

  Management fees and operating expenses charged to the Plan for investments in mutual funds are deducted from income earned on a daily basis and are not separately reflected. Consequently, management fees and operating expenses are reflected as a reduction of net appreciation in fair value of investments for such investments.

  Payment of Benefits

  Benefits are recorded when paid.

2.      INVESTMENTS

  Investments representing 5% or more of the Plan’s net assets available for benefits are as follows at December 31:

2005 2004


Mutual Funds            
   Fidelity Spartan U.S. Equity Index Fund   $ 1,544,289   $ 1,659,911

3.      PARTY-IN-INTEREST TRANSACTIONS

  Parties-in-interest are defined under Department of Labor (DOL) regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others. The Plan's investment in participant loans and Macatawa Bank Corporation common stock as of December 31, 2005 and 2004 represent party-in-interest investment transactions.

  Macatawa Bank Corporation, through its trust department, serves as trustee, custodian, and recordkeeper for the Plan. Therefore, all transactions between the Plan and Macatawa Bank constitute party-in-interest transactions. Cash dividends of $18,743 and $7,618 were paid to the Plan by Macatawa Bank Corporation during 2005 and 2004, respectively.

  The 34,977 and 21,361 shares of Macatawa Bank Corporation common stock held by the Plan as of December 31, 2005 and 2004 represent approximately 0.34% and 0.24% of the Corporation's outstanding shares as of December 31, 2005 and 2004, respectively.

4.      INCOME TAX STATUS

  The Corporation's Board of Directors adopted the Macatawa Bank Prototype 401(k) plan document. The Plan document has received an opinion letter from the Internal Revenue Service dated January 12, 2004, stating that the written form of the underlying prototype plan document is qualified under Section 401(a) of the Internal Revenue Code (the "Code") and that any employer adopting this form of the Plan will be considered to have a plan qualified under Section 401(a) of the Code. The Plan is required to operate in conformity with the Code to maintain its qualification. The Plan's administrator believes the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes the Plan is qualified and the related trust is tax exempt.

5.      PLAN TERMINATION

  Although it has not expressed any intent to do so, Macatawa Bank Corporation has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA.

6.      RISKS AND UNCERTAINTIES

  The Plan provides for investment options in various mutual funds and Macatawa Bank Corporation common stock. Investment securities are exposed to various risks, such as, interest rate, market and credit risks. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term and that such changes could materially affect participants' account balances and the amounts reported in the statements of net assets available for benefits.

7.      RECONCILIATION OF FINANCIAL STATEMENTS TO SCHEDULE H OF FORM 5500

  Refunds of excess contributions represents amounts owed to highly compensated individuals as a result of IRS nondiscrimination testing. This amount is accrued for financial statement purposes and recorded when paid in the Form 5500.

  The following is a reconciliation of net assets available for benefits reported in these financial statements to the amounts reported on Form 5500 at December 31, 2005:

Net assets available for benefits reported        
    in these financial statements   $ 12,631,780  
Refunds of excess contributions    12,363  

   
Net assets available for benefits reported on   
    the Form 5500    $ 12,644,143
