REPORT OF INDEPENDENT AUDITORS

Plan Administrator of
   Firstbank Corporation Amended and Restated
   401(k) and Employee Stock Ownership Plan
Alma, Michigan

We have audited the accompanying statements of net assets available for benefits of the Firstbank Corporation Amended and Restated 401(k) and Employee Stock Ownership Plan as of December 31, 2001 and 2000, and the related statement of changes in net assets available for benefits for the year ended December 31, 2001. These financial statements 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 auditing standards generally accepted in the United States of America. 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 benefits of the Plan as of December 31, 2001 and 2000, and the changes in net assets available for benefits for the year ended December 31, 2001 in conformity with accounting principles generally accepted in the United States of America.

Our audit was conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The 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. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements as a whole.

3

The schedule of assets (held at end of year) that accompanies the Plan's financial statements does not disclose the historical cost of certain non-participant directed Plan assets held by the Plan trustee. Disclosure of this information is required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.

NOTES TO FINANCIAL STATEMENTS
December 31, 2001 and 2000

NOTE 1 - DESCRIPTION OF PLAN

The following description of the Firstbank Corporation Amended and Restated 401(k) and Employee Stock Ownership Plan (the Plan) is provided for general information purposes only. Participants should refer to the Plan agreement for a more complete description of the Plan's provisions.

General: The Plan was established by the plan sponsor, Firstbank Corporation (the Company), effective January 1, 1988. Firstbank - Alma, a subsidiary bank of Firstbank Corporation, acts as trustee for the Plan assets. The Plan is a defined contribution plan which covers all employees who are at least 21 years of age and have completed 90 days of service. The Plan has two primary features: a contributory 401(k) portion based on elective contributions from participants in the Plan and Employee Stock Ownership Plan (ESOP) provisions. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions: Elective deferrals by participants under the 401(k) provisions are based on a percentage of their compensation as defined in the Plan agreement which are subject to certain limitations. The Company may, at the sole discretion of the Board of Directors, contribute to each participant's account a matching contribution which is a percentage of the participant's elective contribution for the year. For 2001 and 2000, the Company made matching contributions equal to 70% of the first 6% of the compensation deferred by each 401(k) participant subject to certain limitations as specified in the Plan agreement.

Participant Accounts: Each participant's account is credited with the participant's contributions and allocation of (a) the Company's contributions and (b) Plan earnings. Allocations are based on participant earnings or account balances, as defined. Forfeitures of employer matching contributions due to participant termination are used to reduce the employer's matching contribution. During 2001, there were forfeitures totaling $18,931. The benefit to which a participant is entitled is the aggregate of the participant's deferrals and rollovers and the vested portion of the employer matching and ESOP contributions.

Investment options: Participants may direct, on a quarterly basis, the trustee to invest their elective 401(k) contributions as well as employer matching contributions to the Plan in any of the available investment options. Participants can individually determine their investment options based on desired level of risk and return for all contributions (employer and employee) to the Plan. Participants have the option to invest their contributions (employer and employee) to purchase common stock of Firstbank Corporation. The ESOP portion of the Plan provides for allocation of shares of Firstbank Corporation common stock to certain qualifying employees as provided by the Plan agreement.

NOTE 1 - DESCRIPTION OF PLAN (Continued)

Retirement, Death and Disability: A participant is entitled to 100% of his or her account balance upon retirement, death or disability while employed.

Vesting: Participants are immediately vested in their elective contributions plus actual earnings thereon. The participants' account values attributable to the Company's contributions, inclusive of ESOP contributions, are vested according to the following schedule:

Completed Years of Service for Vesting (as defined in Plan agreement)	Vested Percentage of the Company's Contribution
1	0	%
2	0
3	25
4	50
5	75
6	100

Payment of Benefits: A participant or his or her beneficiary receives the vested portion in the participant's account in a lump-sum. A participant may receive the portion of his or her account invested in Firstbank stock as stock or in cash.

Loan Provisions: The Plan provides that participants can borrow funds against their account balances up to 50% of their vested account balance less the ESOP balance, or $50,000, whichever is less. The loans are secured by the balance in the participant's account and bear interest rates that range from 6.5% to 13.5%.

Expenses: All administrative expenses are paid by the Plan sponsor.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Investment Valuation and Income Recognition: Investments are stated at fair value. Mutual fund shares and Firstbank Corporation common stock are traded on national exchanges and are valued at the last sales price on the date of valuation. Participant loans are valued at cost which approximates fair value. The investment accounts include cash in short-term money market funds, which has been designated to be invested in the common stock or mutual funds.

Purchases and sale 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.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the plan administrator to make estimates and assumptions that affect certain reported amounts and disclosures, and actual results may differ from these estimates.

Payment of Benefits: Benefits are recorded when paid.

NOTE 3 - PLAN TERMINATION

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of plan termination, participants would become 100% vested in their employer contributions.
