FORWARD LOOKING STATEMENTS

This annual report on Form 10-K including, without limitation, management's
discussion and analysis of financial conditions and results of operations and
other sections of the Corporation's Annual Report to Shareholders which are
incorporated by reference in this report contain forward looking statements that
are based on management's beliefs, assumptions, current expectations, estimates
and projections about the financial services industry, the economy, and about
the Corporation itself. Words such as "anticipate, " "believe," "determine,"
"estimate," "expect," "forecast," "intend," "is likely," "plan," "project,"
"opinion," variations of such terms, and similar expressions are intended to
identify such forward looking statements. The presentations and discussions of
the provision and allowance for loan losses, and determinations as to the need
for other allowances presented or incorporated by reference in this report are
inherently forward looking statements in that they involve judgments and
statements of belief as to the outcome of future events. These statements are
not guarantees of future performance and involve certain risks, uncertainties,
and assumptions that are difficult to predict with regard to timing, extent,
likelihood, and degree of occurrence. Therefore, actual results and outcomes may
materially differ from what may be expressed or forecasted in such forward
looking statements. Internal and external factors that may cause such a
difference include changes in interest rates and interest rate relationships;
demand for products and services; the degree of competition by traditional and
non-traditional competitors; changes in banking regulations; changes in tax
laws; changes in prices, levies, and assessments; the impact of technological
advances; governmental and regulatory policy changes; the outcomes of pending
and future litigation and contingencies; trends in customer behavior and
customer ability to repay loans; software failure; errors or miscalculations;
changes in accounting principles, policies and guidelines; and the vicissitudes
of the national economy. The Corporation undertakes no obligation to update,
amend or clarify forward looking statements, whether as a result of new
information, future events, or otherwise.

PART I

ITEM 1. Business.

Firstbank Corporation (the "Corporation") is a bank holding company. The
Corporation owns all of the outstanding stock of Firstbank - Alma, Firstbank
(Mount Pleasant), Firstbank - West Branch, Firstbank - Lakeview, Firstbank - St.
Johns, and Gladwin Land, Co. (a real estate appraisal company).

The Corporation's business is concentrated in a single industry segment --
commercial banking. Each subsidiary bank of the Corporation is a full-service,
community bank. The subsidiary banks offer all customary banking services,
including the acceptance of checking, savings, and time deposits, and the making
of commercial, mortgage (principally single family), home improvement,
automobile, and other consumer loans. Firstbank - Alma also offers trust
services.

Firstbank - West Branch owns 1st Armored, Incorporated (an armored car
service provider), 1st Collections, Incorporated (a collection service), 1st
Title, Incorporated (a title insurance company), and 1st Real Estate,
Incorporated (which became C.A. Hanes Realty, Incorporated as of January 2,
2001). Each of the subsidiary banks also offers securities brokerage services at
their main offices through arrangements with third party brokerage firms.

The principal sources of revenues for the Corporation and its subsidiaries
are interest and fees on loans. On a consolidated basis, interest and fees on
loans accounted for approximately 82 percent of total revenues in 2000, 78
percent of total revenues in 1999, and 76 percent of total revenues in 1998. In
addition, interest income from investment securities accounted for approximately
8 percent of total revenues on a consolidated basis in 2000, 10 percent of total
revenues on a consolidated basis in 1999, and 10.4 percent of total revenues on
a consolidated basis in 1998. No other single source of revenue accounted for 15
percent or more of the Corporation's total revenues in any of the last three
years. The Corporation has no foreign assets and no income from foreign sources.
The business of the subsidiary banks of the Corporation is not seasonal to any
material extent.

Firstbank - Alma is a Michigan state chartered bank. It and its
predecessors have operated continuously in Alma, Michigan, since 1880. Its main
office and one branch are located in Alma. Firstbank - Alma also has one full
service branch located in each of the following communities near Alma: Ashley,
Auburn, Ithaca, Merrill, Pine River Township, Riverdale, St. Charles, St. Louis,
and Vestaburg.

-1-

Firstbank (Mount Pleasant) is a Michigan state chartered bank which was
incorporated in 1894. Its main office and one branch are located in Mount
Pleasant, Michigan. Firstbank also has two full service offices in Union
Township and one full service branch located in each of the following
communities near Mount Pleasant: Clare, Shepherd and Winn.

Firstbank - West Branch is a Michigan state chartered bank which was
incorporated in 1980. Its main office and two branches are located in West
Branch, Michigan. Firstbank - West Branch also has one full service branch
located in each of the following communities near West Branch: Fairview, Hale,
Higgins Lake, Rose City, St. Helen, and West Branch Township.

Firstbank - Lakeview is a Michigan state chartered bank which was
established in 1904. Its main office and one branch are located in Lakeview, and

established in 2000. Its main office is located in downtown St. Johns. It plans
to establish its first branch office in the St. Johns area during the year 2001.

The following table shows comparative information concerning the
Corporation's subsidiary banks at December 31, 2000:

Loans 174,094 145,248 159,690 105,076 16,658


As of December 31, 2000, the Corporation and its subsidiaries employed 267
persons on a full time equivalent basis.

Banking in the Corporation's market areas and in the State of Michigan is
highly competitive. In addition to competition from other commercial banks,
banks face significant competition from nonbank financial institutions. Savings
and loan associations are able to compete aggressively with commercial banks for
deposits and loans. Credit unions and finance companies are also significant
factors in the consumer loan market. Insurance companies, investment firms, and
retailers are significant competitors for investment products. Banks compete for
deposits with a broad spectrum of other types of investments such as mutual
funds, debt securities of corporations, and debt securities of the federal
government, state governments, and their respective agencies. The principal
methods of competition for financial services are price (interest rates paid on
deposits, interest rates charged on loans, and fees charged for services) and
service (the convenience and quality of services rendered to customers).

The Corporation's subsidiary banks compete directly with other banks,
thrift institutions, credit unions and other nondepository financial
institutions in four geographic banking markets where their offices are located.
Firstbank - Alma primarily competes in Gratiot, Midland, Montcalm, and Saginaw
Counties; Firstbank (Mount Pleasant) primarily in Isabella and Clare Counties;
Firstbank - West Branch primarily in Iosco, Oscoda, Ogemaw, and Roscommon
Counties; Firstbank - Lakeview primarily in Mecosta and Montcalm Counties, and
Firstbank - St. Johns primarily in Clinton County.

Banks and bank holding companies are extensively regulated. The Corporation
is a bank holding company that is regulated by the Federal Reserve System.
Firstbank - Alma, Firstbank (Mount Pleasant), Firstbank - West Branch, Firstbank
- - Lakeview, and Firstbank - St. Johns are chartered under state law and are
supervised, examined, and regulated by the Federal Deposit Insurance Corporation
and the Division of Financial Institutions of the Michigan Office of Financial
and Insurance Services.

Laws that govern banks significantly limit their business activities in a
number of respects. Prior approval of the Federal Reserve Board, and in some
cases various other governing agencies, is required for the Corporation to
acquire control of any additional banks or branches. The business activities of
the Corporation and its subsidiaries are limited to banking and to other
activities which are determined by the Federal Reserve Board to be closely
related to banking. Transactions among the Corporation and the Corporation's
subsidiary banks are significantly restricted. In addition, bank regulations
govern the ability of the subsidiary banks to pay dividends or make other
distributions to the Corporation.

-2-

In addition to laws that affect businesses in general, banks are subject to
a number of federal and state laws and regulations which have a material impact
on their business. These include, among others, state usury laws, state laws
relating to fiduciaries, the Truth In Lending Act, the Truth in Savings Act, the
Equal Credit Opportunity Act, the Fair Credit Reporting Act, the Expedited Funds
Availability Act, the Community Reinvestment Act, the Home Mortgage Disclosure
Act, the Real Estate Settlement Procedures Act, the Bank Secrecy Act, the
Community Development and Regulatory Improvement Act, the Financial Institutions
Reform, Recovery and Enforcement Act, the FDIC Improvement Act of 1991 (the
"FDIC Improvement Act"), electronic funds transfer laws, redlining laws,
antitrust laws, environmental laws, and privacy laws.

The enactment of the Gramm-Leach-Bliley Act of 1999 (the "GLB Act")
represents a pivotal point in the history of the financial services industry.
The GLB Act sweeps away large parts of a regulatory framework that had its
origins in the Depression Era of the 1930s. Effective March 11, 2000, new
opportunities became available for banks, other depository institutions,
insurance companies and securities firms to enter into combinations that permit
a single financial services organization to offer customers a more complete
array of financial products and services. The GLB Act provides a new regulatory
framework for regulation through the "financial holding company," which will
have as its umbrella regulator the Federal Reserve Board. Functional regulation
of the financial holding company's separately regulated subsidiaries will be
conducted by their primary functional regulator. In order to qualify as a
financial holding company, a bank holding company must file an election to
become a financial holding company and each of its banks must be "well
capitalized" and "well managed." In addition, the GLB Act makes satisfactory or
above Community Reinvestment Act compliance for insured depository institutions
and their financial holding companies necessary in order for them to engage in
new financial activities. The GLB Act provides a federal right to privacy of
non-public personal information of individual customers. The Corporation and its
subsidiary banks are also subject to certain state laws that deal with the use
and distribution of non-public personal information.

The Corporation believes that the GLB Act could significantly increase
competition in its business and is evaluating the desirability of electing to
become a financial holding company. The Corporation believes that it is
qualified to elect financial holding company status but has not yet decided to
do so.

The instruments of government monetary policy, as determined by the Federal
Reserve Board, may influence the growth and distribution of bank loans,
investments, and deposits, and may also affect interest rates on loans and
deposits. These policies have a significant effect on the operating results of
banks.

Under applicable laws, regulations, and policies, the Corporation is
expected to act as a source of financial strength to each subsidiary bank and to
commit resources to support each subsidiary bank. Any insured depository
institution owned by the Corporation may be assessed for losses incurred by the
Federal Deposit Insurance Corporation (the "FDIC") in connection with assistance
provided to, or the failure of, any other insured depository institution owned
by the Corporation.

The FDIC has authority to impose special assessments on insured depository
institutions to repay FDIC borrowings from the United States Treasury or other
sources and to establish periodic assessment rates on Bank Insurance Fund
("BIF") member banks so as to maintain the BIF at the designated reserve ratio
defined in the FDIC Improvement Act. Firstbank - Alma and Firstbank (Mount
Pleasant) also hold deposits that are insured by the Savings Association
Insurance Fund ("SAIF") administered by the FDIC. Deposit insurance premiums on
those deposits are paid to the SAIF at rates applicable to that fund. The FDIC
has implemented a system of risk-based premiums for deposit insurance pursuant
to which the premiums paid by a depository institution will be based on the
perceived probability that the insurance funds will incur a loss in respect of
that institution.

Federal law allows bank holding companies to acquire banks located in any
state in the United States without regard to geographic restrictions or
reciprocity requirements imposed by state law and to establish interstate branch
networks through acquisitions of other banks. Michigan and federal law permits
both U.S. and non U.S. banks to establish branch offices in Michigan. The
Michigan Banking Code permits, in appropriate circumstances and with the
approval of the Commissioner: (i) acquisition of Michigan banks by FDIC insured
banks, savings banks, or savings and loan associations located in other states;
(ii) sale by a Michigan bank of branches to an FDIC insured bank, savings bank,
or savings and loan association located in a state in which a Michigan bank
could purchase branches of the purchasing entity; (iii) consolidation of
Michigan banks and FDIC insured banks, savings banks, or

-3-

savings and loan associations located in other states having laws permitting
such consolidation; (iv) establishment of branches in Michigan by FDIC insured
banks located in other states, the District of Columbia, or U.S. territories or
protectorates having laws permitting a Michigan bank to establish a branch in
such jurisdiction; and (v) establishment by foreign banks of branches located in
Michigan.

Risk based capital and leverage standards apply to all banks under federal
regulations. The risk-based capital ratio standards establish a systematic
analytical framework that is intended to make regulatory capital requirements
sensitive to differences in risk profiles among banking organizations, take off
balance sheet liability exposures into explicit account in assessing capital
adequacy, and minimize disincentives to hold liquid, low risk assets. Risk-based
capital ratios are determined by allocating assets and specified off-balance
sheet commitments into risk-weighting categories. Higher levels of capital are
required for categories perceived as representing greater risk.

Failure to meet minimum capital ratio standards could subject a bank to a
variety of enforcement remedies available to the federal regulatory authorities,
including restrictions on certain kinds of activities, restrictions on asset
growth, limitations on the ability to pay dividends, the issuance of a directive
to increase capital, and the termination of deposit insurance by the FDIC.
Maintaining capital at "well capitalized" levels is one condition to the
assessment of federal deposit insurance premiums at the lowest available rate.

Each of the Corporation's subsidiary banks, and the Corporation itself on a
consolidated basis, maintains capital at levels which exceed both the minimum
and well capitalized levels under currently applicable regulatory requirements.
The following table summarizes compliance with regulatory capital ratios by the
Corporation and each of its subsidiary banks at December 31, 2000.


Tier 1 Tier 1 Total
Leverage Capital Risk-based
Ratio Ratio Capital
----- ----- -------

Minimum regulatory requirement 4% 4% 8%

The nature of the business of the Corporation's subsidiaries is such that
they hold title, on a temporary or permanent basis, to a number of parcels of
real property. These include property owned for branch offices and other
business purposes as well as properties taken in or in lieu of foreclosures to
satisfy loans in default. Under current state and federal laws, present and past
owners of real property may be exposed to liability for the cost of remediation
of contamination on or originating from such properties, even though they are
wholly innocent of the actions which caused the contamination. Such liabilities
can be material and can exceed the value of the contaminated property.

Total nonperforming assets $2,645 $3,394 $2,024 $3,273 $1,187


Nonperforming assets are defined as nonaccrual loans, loans 90 days or
more past due, property from defaulted loans, and renegotiated loans.

The gross interest income that would have been recorded for the year ended
December 31, 2000, if the nonaccrual and renegotiated loans had performed in
accordance with their original terms and had been outstanding throughout the
period, or since origination if held for part of the period, was $51,730. The
amount of interest income on those loans that was included in net income for the
period was $140,614.

Loan performance is reviewed regularly by external loan review specialists, loan
officers, and senior management. When reasonable doubt exists concerning
collectibility of interest or principal, the loan is placed in nonaccrual
status. Any interest previously accrued but not collected at that time is
reversed and charged against current earnings.

At December 31, 2000, the Corporation had $18,644,000 in commercial and mortgage
loans for which payments are presently current although the borrowers are
experiencing financial difficulties. Those loans are subject to special
attention and their status is reviewed on a monthly basis.

As of December 31, 2000, there were no concentrations of loans exceeding 10
percent of total loans which are not otherwise disclosed as a category of loans
in the consolidated balance sheets of the Corporation contained in the
Corporation's Annual Report to shareholders for the year ended December 31,
2000.

PRESIDENT'S MESSAGE

TO OUR SHAREHOLDERS:

On behalf of the employees, officers, and directors of Firstbank Corporation, I
am pleased to report that we enjoyed record profits and growth during 2000,
which was a year marked by steadily rising interest rates, stock market
volatility, and further consolidation within the financial services industry. We
achieved these results by maintaining our focus on asset quality, balance sheet
growth, and customer service, while continuing to position ourselves as the
community banking alternative to regional and national providers.

This report will highlight some of our achievements during 2000, and will
introduce you to several of the individuals who serve as directors on the boards
of our subsidiary banks. These individuals, along with all of their fellow
directors, provide unique links to our communities and customers that give us a
market advantage over our larger competitors. Their contributions to the growth
and success of our banks, our Company, and the communities we serve, are
sincerely appreciated.

Earnings. Net income for 2000 was $8,543,000 which was the highest level of
earnings ever achieved by our Company. These earnings represent $1.73 diluted
earnings per share adjusted for the 5% stock dividend paid in December 2000, a
9.50% increase over the $1.58 diluted earnings per share in 1999. These record
earnings improved our return on average equity to 13.63% from the 13.23% posted
in 1999.

Asset Quality. We maintained our focus on asset quality during 2000 realizing
that an economic downturn may occur in the near future. Net charge offs during
2000 were very low, representing only .04% of average loans. The reserve for
loan losses now exceeds $9,857,000 which represents 1.64% of total loans at year
end. Our net charge off ratio continues to compare favorably with our peer
banks. When coupled with our high quality loan portfolio, strong independent
loan review program, and sustained history of low loan losses, we believe our
reserves for potential loan losses appropriately reflect the inherent risks.

Growth. Total assets and total loans reached record levels on December 31, 2000.
Total assets increased 13% during the year to $733 million at year end. Total
loans increased to $601 million, an 18.3% increase when compared with total
loans of $508 million at year end 1999. In addition to strong growth within our
current markets, growth was stimulated by two specific initiatives within the
Company. Our newest bank subsidiary, Firstbank - St. Johns, opened in June 2000
and had over $22 million of total assets by year end, which was substantially
ahead of our initial projections. Firstbank in Mt. Pleasant continued to
emphasize the "Commercial Loan Participation" program, introduced in September
1999, through which other banks may service their large customer loan requests
in cooperation with Firstbank. Over $25 million of loans were approved through
this program during 2000. In addition to generating high quality earning assets
for our Company, this program has helped to establish and improve our
relationships with other Michigan community banks.

Expansion. In addition to establishing Firstbank - St. Johns we entered several
new lines of business during 2000 in an effort to enhance and expand our
mortgage lending business. In March of 2000 we opened 1st Title, which is a
title insurance agency providing service to customers of all five of our banks
as well as to other real estate professionals. In June we acquired Gladwin Land
Company, Inc. which provides real estate appraisal services throughout central
and northeastern Michigan. In November we formed 1st Realty, Inc., in order to
acquire a real estate agency in West Branch, and in January 2001 we merged 1st
Realty with C.A. Hanes Real Estate Company, a leading real estate agency in that
area of Michigan. These organizations all complement our core banking business,
and provide us the tools to more quickly and economically serve the needs of
customers involved in real estate transactions. We believe that our ability to
be a "one stop" source of real estate services for both our customers, and the
customers of other lenders doing business in our markets, will result in
additional fee income in the future.

Efficiency. During 2000 we continued to closely monitor all of our costs in an
effort to operate as economically as possible. A centralized purchasing function
was established, and the adoption of the "Firstbank" name and logo by each of
our bank affiliates will reduce future costs while simultaneously improving our
customer service and brand recognition.

Management. We continue to have strong management teams at each of our
subsidiaries, and the holding Company staff has been strengthened during the
year to assure the highest level of service to all of our customers. Mr. Samuel
G. Stone joined the Company in November 2000 as Vice President and Chief
Financial Officer with substantial financial experience in a regional bank
holding company. His particular knowledge in the areas of capital management,
strategic planning, and mergers and acquisitions will serve us well in the
future. Mr. David Miller, who had been serving as Senior Vice President of
Firstbank - Lakeview, was appointed Vice President of the Company in December
2000 and is now responsible for human resources, training, sales, and marketing.

Shareholder Return. During 2000 the total return to Firstbank Corporation
shareholders (including reinvestment of cash dividends) was 5.1%, bringing the
compound average annual return to 21.1% during the last five years. An
investment in the S&P 500 for that same five year period has produced a compound
average annual return of 18.3%, while the KBW 50 and NASDAQ Bank indexes (which
are composites of large bank and smaller bank results) had five year returns of
21.0% and 19.2%, respectively. Our stock price has reflected the volatility of
the stock market during the past few years, but as these returns indicate, our
total return to shareholders compares favorably to the benchmarks. Be assured
that we remain committed to increasing shareholder value, and that our focus on
growth, asset quality and earnings should result in improved valuation of our
stock over the long term.

Strategy. Our Company's fundamental strategy is that community banks which have
strong local boards and management teams, focused on growth and asset quality,
will outperform regional and national competitors, to the benefit of
shareholders, customers, communities, and employees. Continued consolidation
within the industry will present us with additional opportunities for further
expansion of our concept of community banking, and we look forward to a bright
future.

In conclusion, I would like to thank Chuck Jennings and Bob Smith for their 13
years of service as directors of our West Branch bank and Alan Stone for his
eight years of service as a director of our Alma bank. The dedication of these
individuals has been greatly appreciated. We would also like to thank Chuck
Jennings for his services as a corporate board member for the past 12 years. We
wish these gentlemen well in their retirement.

I would like to thank our dedicated and hard-working staff members. Now over 400
strong, they have made our success possible. It is the quality of our people
that allows us to provide the products and the services that retain and attract
customers to our Company. Their efforts are sincerely appreciated.

Thank you for your investment in Firstbank Corporation. We appreciate the
support and encouragement of our shareholders, and always welcome your comments
or suggestions.

Respectfully submitted,


/s/ Thomas R. Sullivan

MANAGEMENT'S DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The purpose of this section of the annual report is to provide a narrative
discussion about Firstbank Corporation's financial condition and results of
operations. Please refer to the consolidated financial statements and the
selected financial data presented in this report in addition to the following
discussion and analysis.


RESULTS OF OPERATIONS

Highlights

The Company posted record net earnings for the ninth consecutive year. Net
income of $8,543,000 exceeded 1999 results of $8,036,000 by 6.3%. For the past
five years, net income has increased at an annual compound growth rate of over
17%. The Company's results reflect continued strength of core banking activities
as opposed to the effect of nonrecurring or unusual factors. Contributing to the
record results of 2000 was an $80 million increase in earning assets.

Management believes that standard performance indicators help evaluate the
Company's performance. The Company posted a return on average assets of 1.24%,
1.32% and 1.30% for 2000, 1999 and 1998, respectively. Total average assets
increased $80 million in 2000, $47 million in 1999, and $100 million in 1998.
Return on average equity was 13.63% in 2000 compared to 13.23% and 12.98% in
1999 and 1998. Average equity increased $2 million in 2000. Basic earnings per
share were $1.76, $1.62 and $1.47 for 2000, 1999, and 1998. Diluted earnings per
share were $1.73, $1.58, and $1.41 for the same time periods. In 1999 and 2000,
the Company repurchased 180,150 and 258,319 shares of its common stock,
completing the Board authorized repurchase program. The interest cost of funding
the repurchase contributed to the decline in return on average assets in 2000.
However, the repurchase helped to maintain capital at the appropriate level and
allow growth in net income to result in increasing return on equity.

Net Interest Income

The core business of the Company is earning interest on loans and securities and
paying interest on deposits and borrowings. In successfully managing this
business, the Company has increased its net interest income by $2 million for
2000, for a 7.5% gain when compared to 1999. Net interest margin declined to
4.63% in 2000 compared to 4.92% in 1999 and 5.06% in 1998, but remains
competitive among peer performance. During 2000, the Company's loan to deposit
ratio was 104% compared to 93% in 1999 and 87% in 1998. Net end of period loans
grew $92 million or 18% during 2000.

A critical task of management is to price assets and liabilities so that the
spread between the interest earned on assets and the interest paid on
liabilities is maximized without unacceptable risks. While interest rates on
earning assets and interest bearing liabilities are subject to market forces, in
general the Company can exert more control over deposit costs than earning asset
rates. Loan products carry either fixed rates of interest or rates tied to
market indices determined independently. The Company sets its own rates on
deposits, providing management with some flexibility in determining the timing
and proportion of rate changes for the cost of its deposits. However,
competitive forces and the need to maintain and grow deposits as a funding
source place limitations on the degree of control over deposit rates.

The following table presents a summary of net interest income for 2000, 1999,
and 1998. In 2000, the average rate realized on earning assets was 8.65%, an
increase of 28 basis points from the 1999 results of 8.37%, and a 17 basis point
reduction from the rate of 8.82% realized in 1998. In 1998, the prime rate was
reduced 25 basis points three times during the fourth quarter. Prime rate
changes in 1999 reversed the 1998 actions with three increases of 25 basis
points each during the last half of 1999. During 2000, the prime rate increased
25 basis points twice in the first quarter, another 50 basis points in the
second quarter, then was unchanged for the balance of the year. As the prime
rate decreases, management expects the yield on earning assets to decrease. At
December 31, 2000, slightly over 18% of the loan portfolio was comprised of
variable rate instruments. Those loans will reprice monthly or quarterly as
rates change. The remaining 82% of the loan portfolio is made up of fixed rate
loans that do not reprice until maturity. Of the fixed rate loans, approximately
$121 million or 23% of the loan portfolio mature within the next twelve months
and are subject to rate adjustments at maturity.

As rates decline, maturing investment securities could not be replaced with
comparable securities bearing higher yields than available a year ago, although
yields would not necessarily be lower than the yields on maturing securities.
Much of the current investment portfolio was purchased in rate environments
similar to the current rate conditions. Although management expects to lose some
yield when replacing investment securities, they do not believe that the
decrease will equate to the basis point decline seen in the prime rate.

The average rate paid on interest bearing liabilities was 4.73% in 2000 compared
to 4.12% and 4.47% in 1999 and 1998 respectively. Deposit products have
experienced increases in cost over the past year as interest rates paid grew in
response to the rise in prime rate. As the prime rate increased in 2000, deposit
rates have also climbed, but not as fast or to the extent of the changes in the
prime rate. The company has funded a portion of its loan growth with borrowings
from the Federal Home Loan Bank. Average outstanding balances increased over $38
million in 2000. While these borrowings are an economical method of funding
loans, the cost is higher than the Company's core deposit costs. The average
rate of Federal Home Loan Bank funding increased 90 basis points in 2000 to
6.37% when compared to 1999 rates of 5.47%. However, Federal Home Loan Bank
rates have begun to decrease along with decreases in the Federal Funds rates.

The 2000 rate spread of 3.92% is 33 basis points lower than 1999 results of
4.25% and a 43 basis point reduction from 4.35% in 1998. Tax equivalent net
interest income increased $1.9 million in 2000 as total average earning assets
grew $76 million. Net interest margin of 4.63% for 2000 was 29 basis points less
than the 1999 results. Although net interest margin decreased, the Company is
performing competitively among peers in this critical measurement. Decreases in
both net interest margin and rate spread are the result of rates on average
earning assets increasing 28 basis points while the average cost of interest
bearing liabilities increased 61 basis points. Average earning assets
represented 93% and 92% of total average assets in 2000 and 1999.

Provision for Loan Losses

The provision for loan losses was $736,000 in 2000 compared to $514,000 in 1999
and $1.2 million in 1998. The increases in the provision for loan losses in 2000
reflect the growth in the loan portfolio, as net charge offs and nonperforming
loans remained at very low levels. At December 31, 2000, the allowance for loan
losses as a percent of total loans was 1.64% compared to 1.83% and 2.05% at
December 31, 1999, and December 31, 1998, respectively. Net charged off loans
totaled $196,000 in 2000 compared to $245,000 in 1999 and $243,000 in 1998.
During 2000, over $628,000 of recoveries were realized contributing to the
year's strong results. Recoveries in 1999 were $554,000 and in 1998 were
$469,000. Net charged off loans as a percent of average loans were .04% in 2000
compared to .05% in 1999 and .06% in 1998. Total nonperforming assets were .46%
of ending loans at December 31, 2000, compared to .67% and .46% at the two
previous year ends. Management maintains the allowance for loan losses at a
level considered appropriate to absorb losses in the portfolio. The allowance
balance is established after considering past loan loss experience, current
economic conditions, volume, growth and composition of the portfolio,
delinquencies and other relevant factors.

Noninterest Income

After a decrease of $499,000, or 8.5%, from 1998 to 1999, total noninterest
income increased $62,000 in 2000. Service charges on deposit accounts increased
$128,000, or 8.12%, from 1999 to 2000. Climbing interest rates in 1999 and the
level of interest rates in 2000 steeply curtailed the mortgage refinancing
market. Trust fees declined $3,000 in 2000, after having increased $53,000 in
1999, as market conditions and the distribution of certain trust assets offset
growth of fees in 2000.

Other noninterest income posted gains of $255,000, or 11%, when comparing 2000
to 1999. Of this increase over $137,000 was from the recognition of market gains
and dividends on the investments underlying the balances in the deferred
compensation accounts. A comparable entry is recorded in other noninterest
expense creating no impact on total net income. Excluding these gains and
dividends, other noninterest income increased $118,000, or 5%, in 2000.

Noninterest Expense

Salary and benefit expense increased $839,000, or 8.0%, during 2000. The
increase is the result of normal salary increments and merit raises, and, in
addition, the Company opened its new full service bank in St. Johns, Michigan,
during 2000, requiring the addition of personnel. The company employed
twenty-three more full time equivalent employees at the end of 2000 than at the
same time in 1999, resulting in the additional increase in salary and employee
benefit cost.

Amortization of intangibles increased $127,000 or 21% in 2000 when compared to
1999. Additional intangible expense was incurred due to the acquisition of
Gladwin Land, Inc., by Firstbank Corporation and a subsidiary's acquisition of a
real estate brokerage company, and the assets of another real estate brokerage
firm.

Other noninterest expense decreased by 3%, or $146,000 in 2000. Management
continues to search for more efficient means of delivering services.

Federal Income Tax

The company's effective tax rates were 31%, 31% and 30% for 2000, 1999 and 1998.
The principal difference between the effective tax rates and the statutory tax
rate of 34% is the Company's investment in securities and loans which provide
income exempt from federal income tax.

FINANCIAL CONDITION

Total assets at December 31, 2000, were $733 million, exceeding the December 31,
1999, assets of $651 million by $82 million or 13%. Loans grew $93 million or
18.2% during 2000 with commercial loans leading the advance by $51 million or
22.5%. Real estate mortgages grew by $35 million, or 16.9%, while consumer loans
posted a moderate $7 million increase or 8.8%. The start up bank and
acquisitions accounted for $22 million assets at Firstbank - St. Johns, $500,000
at Gladwin Land, and $620,000 at our real estate subsidiary, now known as C.A.
Hanes Realty, Incorporated ("C.A. Hanes").

Mortgages serviced for others $238,800 $233,660 $ 5,140 2.2%

A portion of the loan growth was funded by a $14 million or 15.6% reduction in
the investment securities portfolio.

Premises and equipment increased $753,000 after recognized depreciation of
$1,394,000. Several projects contributed to this increase. During 2000, the
Company opened a new affiliate bank and purchased Gladwin Land, Incorporated.
One affiliate converted a previously purchased property into a new branch which
opened in May, 2000, and one affiliate purchased 1st Realty, Incorporated (which
later merged with C.A. Hanes).

Total deposits increased at the end of 2000 to $537 million, an increase of
$45.8 million, or 9%. While interest demand accounts declined a modest .5%, or
$700,000, noninterest demand deposits increased $4.5 million or 6% for a net
increase in demand deposit products of $3.8 million. Savings accounts declined
$2 million, or 2.6%, while time deposits increased $44 million, or 21%.
Securities sold under agreements to repurchase remained constant at $22 million.

Notes payable increased $45.6 million at December 31, 2000, as compared to
December 31, 1999. As loan growth has outstripped deposit growth, the Company
used Federal Home Loan Bank borrowings and reductions in investments to fund the
increase in loans. Overnight borrowings decreased $13.6 million from year end
1999 to 2000. Note J has a more complete discussion of borrowings.

Asset Quality

Management continues to follow a conservative course in the recognition of
problem loans. In most cases, when a loan reaches 90 days past due, all income
earned but not collected is deducted from current income. Loans are carried at
an amount which management believes will be collected. A balance considered not
collectible is charged against (reduction of) the allowance for loan losses. In
2000, net charged off loans were $196,000 compared to $245,000 in 1999. Net
charged off loans as a percentage of average loans were .04% and .05% in 2000
and 1999.

Nonperforming loans are defined as nonaccrual loans, loans 90 days or more past
due, and any loans where the terms have been renegotiated. Total nonperforming
loans were $2.2 million and $2.9 million at December 31, 2000 and 1999. The
investment in impaired loans was $5.8 million at December 31, 2000, compared to
$4.7 million at December 31, 1999. Please refer to Note F to the consolidated
financial statements for more information on impaired loans. Total nonaccrual
loans were $1.7 million at December 31, 2000, compared to $2.2 million at the
end of 1999.

The allowance for loan losses increased $540,000 or 5.8% during 2000. The
allowance for loan losses represents 1.64% of outstanding loans at the end of
2000 as compared to 1.83% at December 31, 1999. Management maintains the
allowance at a level which they believe adequately provides for losses inherent
in the loan portfolio. Such losses are estimated by a variety of factors,
including specific examination of certain borrowing relationships and
consideration of historical losses incurred on certain types of credits.
Management focuses on early identification of problem credits through ongoing
review by management, loan personnel and an outside loan review specialist.

LIQUIDITY AND INTEREST RATE SENSITIVITY

Asset liability management aids the Company in achieving reasonable and
predictable earnings and liquidity while maintaining a balance between interest
earning assets and interest bearing liabilities. Liquidity management involves
the ability to meet the cash flow requirements of the Company's customers. These
customers may be either borrowers needing to meet their credit needs or
depositors wanting to withdraw funds. Management of interest rate sensitivity
attempts to avoid widely varying net interest margins and to achieve consistent
net interest income through periods of changing interest rates. The net interest
margin was 4.63% in 2000 compared to 4.92% in 1999. Loan yields were 8.93% in
2000 compared to 8.75% in 1999. Deposit costs increased 31 basis points from
4.10% in 1999 to 4.41% in 2000. Notes payable increased as a funding source,
with average balances of $63,692,000 in 2000 compared to $17,777,000 in 1999. In
2000, the average cost of funds on notes payable was 6.48%, compared to 4.41% on
deposits.

An increase in deposit rates affects most rates currently paid and, therefore,
has an immediate negative impact on net interest margin. With the exception of
variable rate loans, an increase in loan rates does not affect the yield until a
new loan is made. The prime rate increased 25 basis points twice during the
first quarter of 2000 and an additional 50 basis points during the second
quarter and then remained unchanged for the last two quarters. In addition to
the increased reliance on notes payable, competition for both loans and deposits
caused margins to shrink in 2000.

The principal sources of liquidity for the Company are maturing securities,
federal funds purchased or sold, loan payments by borrowers, investment
securities, loans held for sale and deposit or deposit equivalent growth.
Securities maturing within one year at December 31, 2000, were $26.6 million
compared to $26.8 million at December 31, 1999.

The following table shows the interest sensitivity gaps for five different
intervals as of December 31, 2000:

Maturity or repricing frequency
-------------------------------
(Dollars in millions)
2 days 4 mos. 13 mos.
through through through
1 day 3 mos. 12 mos. 5 yrs. 5+ yrs.

Interest earning assets:
Loans $ 94.9 $ 67.1 $ 87.8 $291.7 $59.2
Investment securities 4.4 6.7 6.9 31.5 26.7
Other earning assets 0.8
-------
Total 100.1 73.8 94.7 323.2 85.9

Interest bearing liabilities:
Deposits 284.9 72.6 130.5 49.2
Other bearing liabilities 16.7 21.4 5.9 22.8 55.5
------ ---- ------- ------ ----
Total 301.6 94.0 136.4 72.0 55.5

Interest sensitivity gap (201.5) (20.2) (41.7) 251.2 30.4

Cumulative gap (201.5) (221.7) (263.4) (12.2) 18.2


For the one day interval, maturities of interest bearing liabilities exceed
those of interest earning assets by $201.5 million. Included in the one day
maturity classification are $284.9 million savings and checking accounts which
are contractually available to the Company's customers immediately, but in
practice, function as core deposits with considerably longer maturities. The
pattern of interest sensitive liability maturities exceeding interest sensitive
assets changes through the five year time frame resulting in a cumulative effect
of $12.2 million through five years. For the time period greater than five
years, the positive trend continues so that interest sensitive assets exceed
interest sensitive liabilities by $18.2 million.

Showing a negative gap through the five year period in a rising rate scenario,
as the Company experienced in 2000, does not necessarily result in a
corresponding decline in net interest income. In practice, the affiliate banks
are able to ameliorate the adverse impact of rising prime rates by trailing the
prime rate increases with deposit rate increases, and adjusting interest paid
rates less than the total change in the prime rate.

Interest rate sensitivity varies with different types of interest earning assets
and interest bearing liabilities. Overnight investments, on which rates change
daily, and loans tied to the prime rate differ considerably from long term
investment securities and fixed rate loans. Time deposits over $100,000 and
money market accounts are more interest sensitive than regular savings accounts.
Comparison of the repricing intervals of interest earning assets to interest
bearing liabilities is a measure of the interest sensitivity gap. Balancing this
gap is a continual challenge in a changing rate environment. The Company uses a
sophisticated computer program to perform analysis of interest rate risk, assist
with its asset liability management, and model and measure interest rate
sensitivity.

QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The Company faces market risk to the extent that both earnings and the fair
values of its financial instruments are affected by changes in interest rates.
The Company manages this risk with static GAP analysis and simulation modeling.
Throughout 2000, the results of these measurement techniques were within the
Company's policy guidelines. While the Company did begin relying more on Federal
Home Loan Bank borrowings in 2000, the Company does not believe that there has
been a material change in the nature of the Company's primary market risk
exposures, including the categories of market risk to which the Company is
exposed and the particular markets that present the primary risk of loss to the
Company, or in how those exposures were managed in 2000 as compared to 1999. As
of the date of this annual report, the Company does not know of or expect there
to be any material change in the general nature of its primary market risk
exposure in the near term.

The Company's market risk exposure is mainly comprised of its vulnerability to
interest rate risk. Prevailing interest rates and interest rate relationships in
the future will be primarily determined by market factors which are outside of
the Company's control. All information provided in response to this item
consists of forward looking statements. Reference is made to the section
captioned "Forward Looking Statements" in this annual report for a discussion of
the limitations on the Company's responsibility for such statements.

The following tables provide information about the Company's financial
instruments that are sensitive to changes in interest rates as of December 31,
2000 and 1999. They show expected maturity date values for loans and investment
securities which were calculated without adjusting the instruments' contractual
maturity dates for expected prepayments. Maturity date values for interest
bearing core deposits were not based on estimates of the period over which the
deposits would be outstanding, but rather the opportunity for repricing. The
Company believes that repricing dates, as opposed to expected maturity dates may
be more relevant in analyzing the value of such instruments and are reported as
such in the following tables. Fair value is computed as the present value of
expected cash flows at rates in effect at the date indicated.

CAPITAL RESOURCES

The Company obtains funds for its operating expenses and dividends to
shareholders through dividends from its subsidiary banks. In general, the
subsidiary banks pay only those amounts required to meet holding company cash
requirements. No excess liquidity is accumulated at the holding company, rather
capital is maintained at the subsidiary banks to support growth.

Bank regulators have established risk based capital guidelines for banks and
bank holding companies. Minimum capital levels are established under these
guidelines. Each asset category is assigned a perceived risk weighting. Off
balance sheet items, such as loan commitments and standby letters of credit,
also require capital allocations.

As of December 31, 2000, the Company's total capital to risk weighted assets
exceeded the minimum requirement for capital adequacy purposes of 8% by 3.28%,
or $18 million, Tier 1 capital to risk weighted assets exceeded the minimum of
4% by 6.03%, or $33 million, and Tier 1 capital to average assets exceeded the
minimum of 4% by 3.77%, or $26 million. For a more complete discussion of
capital requirements, please refer to Note R to the consolidated financial
statements.

The Federal Deposit Insurance Corporation insures specified customer deposits
and assesses premium rates based on defined criteria. Insurance assessment rates
may vary from bank to bank based on the factors that measure the perceived risk
of a financial institution. One condition for maintaining the lowest risk
assessment, and therefore the lowest insurance rate, is the maintenance of
capital at the "well capitalized" level. Each of the Company's affiliate banks
has exceeded the regulatory criteria for a "well capitalized" financial
institution, and is paying the lowest assessment rate assigned by FDIC.

A certain level of capital growth is desirable to maintain a good ratio of
equity to total assets. The compound annual growth rate for total average assets
for the past five years was 15.8%. The compound annual growth rate for average
equity over the same period was 17.9%.

Management has determined one way of maintaining capital adequacy is to maintain
a reasonable rate of internal capital growth. The percentage return on average
equity times the percentage of earnings retained after dividends equals the
internal growth percentage. The following table illustrates this relationship:

2000 1999 1998
---- ---- ----

Return on Equity 13.63% 13.23% 12.98%
multiplied by
Percentage of Earnings Retained 63.27% 64.22% 65.84%
equals
Internal Capital Growth 8.63% 8.49% 8.55%

The Company has retained between 63% and 66% of its earnings from 1998 to 2000.
To maintain sufficient capital, management has determined that the rate of
internal capital growth should exceed 5% and keep pace with asset growth over
time. To achieve the goal of acceptable internal capital growth, management
intends to continue its efforts to increase the Company's return on average
equity while maintaining a reasonable cash dividend.

As an additional enhancement to capital growth, the Company offers a dividend
reinvestment program. The Firstbank Corporation Dividend Reinvestment Plan was
first offered in 1988. At December 31, 1988, 123 owners holding 209,856 shares
participated in the Plan. By the end of 2000, 1,225 owners holding 1,870,849
shares were participating in the Plan.

The Company is not aware of any recommendations by regulatory authorities at
December 31, 2000, which are likely to have a material effect on Firstbank
Corporation's liquidity, capital resources or operations.

The Company's principal sources of funds to pay cash dividends are the earnings
of and dividends paid by the subsidiary banks. Under current regulations, the
subsidiary banks are restricted in their ability to transfer funds in the form
of cash dividends, loans and advances to the Company (See Note P). As of January
1, 2001, approximately $11,646,000 of the subsidiaries' retained earnings were
available for transfer in the form of dividends to the Company without prior
regulatory approval. In addition, the subsidiaries' 2001 earnings will be
available for distributions as dividends to the Company.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE A - SIGNIFICANT ACCOUNTING POLICIES

Nature of Operations: Firstbank Corporation (the "Company") is a bank holding
company. Each subsidiary bank of the Company is a full service community bank.
The subsidiary banks offer all customary banking services, including the
acceptance of checking, savings and time deposits, and the making of commercial,
agricultural, real estate, personal, home improvement, automobile and other
installment and consumer loans. Trust services are provided throughout the
Company's service area by one of its subsidiary banks. The consolidated assets
of the Company of $733 million as of December 31, 2000, primarily represent
commercial and retail banking activity. Mortgage loans serviced for others of
$239 million and trust assets of $59 million as of December 31, 2000, are not
included in the Company's consolidated balance sheet.

Principles of Consolidation: The consolidated financial statements include the
accounts of the Company and its wholly owned subsidiaries: Firstbank - Alma;
Firstbank (Mt. Pleasant); Firstbank - West Branch; Firstbank - Lakeview; and
Firstbank - St. Johns (the "Banks"); 1st Armored, Incorporated; 1st Collections,
Incorporated; Gladwin Land Company; 1st Title, Incorporated; and 1st Realty
Incorporated; after elimination of intercompany accounts and transactions. (See
Note B regarding 1st Realty Incorporated.)

Use of Estimates: The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the reported
period. Actual results could differ from those estimates.

Certain Significant Estimates: The primary estimates incorporated into the
Company's financial statements which are susceptible to change in the near term
include the allowance for loan losses and the determination and carrying value
of certain financial instruments.

Current Vulnerability Due to Certain Concentrations: The Company's business is
concentrated in the mid-central section of the lower peninsula of Michigan.
Management is of the opinion that no concentrations exist that make the Company
vulnerable to the risk of a near term severe impact. While the loan portfolio is
diversified, the customers' ability to honor their debts is partially dependent
on the local economies. The Company's service area is primarily dependent on the
manufacturing (automotive and other), agricultural and recreational industries.
Most commercial and agricultural loans are secured by business assets, including
commercial and agricultural real estate and federal farm agency guarantees.
Generally, consumer loans are secured by various items of personal property and
mortgage loans are secured by residential real estate. The Company's funding
sources include time deposits and other deposit products which bear interest.
Periods of rising interest rates result in an increase in the cost of funds to
the Company.

Cash and Cash Equivalents: Cash and cash equivalents include cash on hand,
amounts due from banks, and short term investments which include interest
bearing deposits with banks, federal funds sold, and overnight money market fund
investments. Generally, federal funds and overnight money market funds are
purchased for a one day period. The Company reports customer loan transactions,
deposit transactions, and repurchase agreements and overnight borrowings on a
net cash flow basis.

Securities Available for Sale: Securities available for sale consist of bonds
and notes which might be sold prior to maturity due to changes in interest
rates, prepayment risks, yield and availability of alternative investments,
liquidity needs or other factors. Securities classified as available for sale
are reported at their fair value and the related unrealized holding gain or loss
(the difference between the fair value and amortized cost of the securities so
classified) is reported, net of related income tax effects, as a separate
component of shareholders' equity until realized. Gains and losses on sales are
determined using the specific identification method. Premium and discount
amortization is recognized in interest income using the level yield method over
the period to maturity.

Mortgage Banking Activities: Servicing rights are recognized as assets for
purchased rights and for the allocated value of retained servicing rights on
loans sold. Servicing rights are expensed in proportion to, and over the period
of, estimated net servicing revenues. Impairment is evaluated based on the fair
value of the rights, using groupings of the underlying loans as to interest
rates and then, secondarily, as to geographic and prepayment characteristics.
Any impairment of a grouping is reported as a valuation allowance.

Loans: Loans receivable, for which management has the intent and ability to hold
for the foreseeable future or payoff, are reported at their outstanding unpaid
principal balances net of any deferred fees or costs on originated loans, or
unamortized premiums or discounts. Loan origination fees and certain origination
costs are capitalized and recognized as an adjustment of the yield of the
related loan. Loans held for sale are reported at the lower of cost or market,
on an aggregate basis.

Allowance for Loan Losses: The allowance for loan losses is a valuation
allowance for probable incurred credit losses. Management's determination of the
adequacy of the allowance is based on an evaluation of the portfolio, past loan
loss experience, current economic conditions, volume, growth and composition of
the loan portfolio and other relevant factors. The allowance is increased by
provisions for loan losses charged to expense and reduced by charge offs, net of
recoveries.

The valuation of loans is reviewed on an ongoing basis for impairment. A loan is
impaired when it is probable that the Company will be unable to collect all
amounts due according to the contractual terms of the loan agreement. Impaired
loans are measured based on the present value of expected cash flows discounted
at the loan's effective interest rate or, as a practical expedient, at the
loan's observable market price or at the fair value of collateral if the loan is
collateral dependent. Loans considered to be impaired are reduced to the present
value of expected future cash flows or to the fair value of collateral, by
allocating a portion of the allowance for loan losses to such loans. If these
allocations cause an increase in the allowance for loan losses, such increase is
reported as provision for loan loss.

Smaller balance homogeneous loans such as residential first mortgage loans
secured by one to four family residences, residential construction loans,
automobile, home equity and second mortgage loans are collectively evaluated for
impairment. Commercial loans and first mortgage loans secured by other
properties are evaluated individually for impairment. When credit analysis of
the borrower's operating results and financial condition indicates the
underlying ability of the borrower's business activity is not sufficient to
generate adequate cash flow to service the business' cash needs, including the
Company's loans to the borrower, the loan is evaluated for impairment. Often
this is associated with a delay or shortfall in payments of 90 days or less.
Commercial loans are rated on a scale of 1 to 8, with grades 1 to 4 being pass
grades, 5 being special attention or watch, 6 substandard, 7 doubtful and 8
loss. Loans graded 6, 7 and 8 are considered for impairment. Loans are generally
moved to nonaccrual status when 90 days or more past due. These loans are often
considered impaired. Impaired loans, or portions thereof, are charged off when
deemed uncollectible.

Premises and Equipment: Premises and equipment are stated on the basis of cost,
less accumulated depreciation. Depreciation is computed over the estimated
useful lives of the assets, primarily by accelerated methods for income tax
purposes, and by the straight line method for financial reporting purposes.

Other Real Estate: Other real estate (included as a component of other assets)
includes properties acquired through either a foreclosure proceeding or
acceptance of a deed in lieu of foreclosure and is initially recorded at fair
value at the date of foreclosure, establishing a new cost basis. These
properties are evaluated periodically and are carried at the lower of cost or
estimated fair value less estimated costs to sell.

Acquisition Intangibles: The acquisition of purchased subsidiaries and branches
has included amounts related to the value of customer deposit relationships
("core deposit intangibles") and excess of cost over estimated fair value of net
assets acquired ("goodwill"). The core deposit intangibles are amortized over
the expected lives of the acquired relationships. The goodwill is amortized
using the straight line method for periods of not less than 15 years or more
than 20 years.

Interest Income: Interest on loans is accrued over the term of the loans based
upon the principal outstanding. The carrying value of impaired loans is
periodically adjusted to reflect cash payments, revised estimates of future cash
flows and increases in the present value of expected cash flows due to the
passage of time. Cash payments representing interest income are reported as such
and other cash payments are reported as reductions in carrying value. Increases
or decreases in carrying value due to changes in estimates of future payments or
the passage of time are reported as reductions or increases in the provision for
loan losses.

Income Taxes: The Company records income tax expense based on the amount of
taxes due on its tax return plus the change in deferred taxes computed, based on
the future tax consequences of temporary differences between the carrying
amounts and tax bases of assets and liabilities, using enacted tax rates.

Earnings Per Share: Basic earnings per share is based on weighted average common
shares outstanding. Diluted earnings per share includes the dilutive effect of
additional common shares issuable under stock options. All per share amounts are
restated for stock dividends and stock splits through the date of issuance of
the financial statements.

Comprehensive Income: Comprehensive income consists of net income and unrealized
gains and losses on securities available for sale, net of tax, which is also
recognized as a separate component of equity. Accumulated other comprehensive
income consists of unrealized gains and losses on securities available for sale,
net of tax.

Reclassification: Certain 1999 and 1998 amounts have been reclassified to
conform to the 2000 presentation.

Future Accounting Changes: Beginning January 1, 2001, a new accounting standard
will require all derivatives to be recorded at fair value. Unless designated as
hedges, changes in these fair values will be recorded in the income statement.
Fair value changes involving hedges will generally be recorded by offsetting
gains and losses on the hedge and on the hedged item, even if the fair value of
the hedged item is not otherwise recorded. Adoption of this standard on January
1, 2001, did not have a material effect on the consolidated financial
statements.

Segment Information: While the Company's chief decision makers monitor the
revenue streams of various products and services, operations are managed and
financial performance is evaluated on a company wide basis. Accordingly, all of
the Company's banking operations are considered by Management to be aggregated
in one reportable operating segment.


NOTE B - ACQUISITIONS/DIVESTURES

On October 20, 2000, Firstbank Corporation, through its affiliate Firstbank -
West Branch, completed the acquisition of Real Estate One, which was re-named
1st Realty, Inc. On January 2, 2001, also through its Firstbank - West Branch
affiliate, Firstbank Corporation completed the acquisition of C.A. Hanes Real
Estate in a transaction that merged C.A. Hanes with 1st Realty, Inc. Firstbank -
West Branch maintains a 55% ownership of the new company which will do business
as C.A. Hanes Realty Inc. This real estate subsidiary complements the prior
acquisitions of Gladwin Land Company and 1st Title, Inc., and these subsidiaries
provide service to all five banks of Firstbank Corporation and position the
banks to provide the full spectrum of services related to real estate
transactions. This acquisition did not have a material effect on the Company's
consolidated financial statements.

On April 1, 1999, the Company's Firstbank - Alma subsidiary sold its insurance
agency, Niles Agency, Incorporated, to an unrelated third party. Operating
results of the Niles Agency are included in consolidated results until the date
of sale. A gain of $59,000 was recognized on the sale of the agency, and is
included in other income of the consolidated statements of income and
comprehensive income. The effect of the operation and sale of the Niles Agency
was not material to the consolidated financial statements of the Company.


NOTE C - RESTRICTIONS ON VAULT CASH AND DUE FROM BANK ACCOUNTS

The Company's subsidiary banks are required to maintain average reserve balances
in the form of cash and noninterest bearing balances due from the Federal
Reserve Bank. The average reserve balances required to be maintained at December
31, 2000 and 1999, were $2,886,000 and $2,765,000 respectively. These balances
do not earn interest.

Average interest rate 4.62% 4.05% 4.15%

Maximum outstanding at any month end $26,374 $21,519 $18,678

Securities sold under agreements to repurchase (repurchase agreements) generally
have original maturities of less than one year. Repurchase agreements are
treated as financings and the obligations to repurchase securities sold are
reflected as liabilities. Securities involved with the agreements are recorded
as assets of the Company and are primarily held in safekeeping by correspondent
banks. Repurchase agreements are offered principally to certain large deposit
customers as deposit equivalent investments.

The Company had $16,650,000 and $30,300,000 in overnight borrowings at December
31, 2000, and 1999.

The Company established a line of credit agreement with Citizens Bank, Flint,
Michigan, on May 24, 2000. This agreement allows for a revolving line of credit
up to an aggregate principal amount of $20,000,000 and has a termination date of
June 30, 2001. The collateral for this agreement consists of all outstanding
capital stock of Firstbank - West Branch, Firstbank - Alma, and Firstbank (Mt.
Pleasant).

At December 31, 2000, the Company has drawn $6,700,000 against the line of
credit at an interest rate of 8.45% which is fixed until March 1, 2001. This
borrowing was made primarily to establish the new bank in St. Johns, Michigan,
and to fund the stock repurchase program.

NOTE L - BENEFIT PLANS

The ESOP is a qualified stock bonus plan, a qualified 401(k) salary deferral
plan and a qualified employee stock ownership plan. Both employee and employer
contributions may be made to the ESOP. At year-end 2000 and 1999, there were
191,655 and 220,315 ESOP shares outstanding with a market value of $3,665,404
and $4,241,067. The Company's 2000, 1999, and 1998 matching 401(k) contributions
charged to expense were $274,000, $276,000, and $264,000 respectively. The
percent of the Company's matching contributions to the 401(k) is determined
annually by the Board of Directors.

The Board of Directors established the Firstbank Corporation Affiliated Deferred
Compensation Plan (Plan). Directors of the holding company and each affiliate
bank are eligible to participate in the Plan. In addition, key management of the
holding company and affiliate banks as designated by the Board of Directors, are
eligible to participate. The Plan is a nonqualified plan as defined by the
Internal Revenue Code. As such, all contributions are invested at the direction
of the participant and are assets of the Company. The Company recognizes a
corresponding liability to each participant. The Plan allows Directors to defer
their director fees and key management to defer a portion of their salaries into
the Plan.

NOTE M - STOCK OPTIONS

The Firstbank Corporation Stock Option Plans of 1993 and 1997 ("Plans") provide
for the grant of 295,491 and 243,101 shares of stock, respectively, in either
restricted form or under option. Options may be either incentive stock options
or nonqualified stock options. The Plan of 1993 will terminate April 26, 2003.
The 1997 Plan will terminate April 28, 2007. The Board, at its discretion, may
terminate either or both Plans prior to the Plans' termination dates.

Each option granted under the Plans may be exercised in whole or in part during
such period as is specified in the option agreement governing that option.
Options are issued with exercise prices equal to the stock's market value at
date of issuance. A nonqualified stock option may not be exercised after fifteen
years from the grant date. Incentive stock options may not be exercised after
ten years from the grant date.

The following is a summary of option transactions which occurred during 1998,
1999 and 2000:

Financial Accounting Standards No. 123, Accounting for Stock Based Compensation
(SFAS 123) establishes a fair value based method of accounting for employee
stock options. Accordingly, the following pro forma information presents net
income and earnings per share information as if SFAS 123 had been adopted. No
compensation cost was actually recognized for stock options in 2000, 1999, or
1998.

2000 1999 1998
---- ---- ----

Net income as reported $8,543,000 $8,036,000 $7,303,000
Pro forma net income $8,424,000 $7,923,000 $7,223,000

Basic earnings per share as reported $1.76 $1.62 $1.47
Pro forma basic earnings per share $1.73 $1.60 $1.45

Diluted earnings per share as reported $1.73 $1.58 $1.41
Pro forma diluted earnings per share $1.71 $1.56 $1.46

In future years, the pro forma effect under this standard is expected to
increase as additional options are granted.

The fair value of options granted during 2000, 1999, and 1998, is estimated
using the Black-Scholes model and the following weighted average information:
risk free interest rate of 5.71%, 6.28%, and 5.06%; expected life of 7 years;
expected volatility of stock price of 19.8%, 36.2%, and 33.9%; and expected
dividends of 3% per year. The fair value of the options granted in 2000, 1999,
and 1998, were $254,000, $235,000, and $207,000 respectively. For options
outstanding at December 31, 2000, the range of exercise prices was $7.36 to
$27.64 and the weighted average remaining contractual life was 6.9 years.

NOTE N - RELATED PARTY TRANSACTIONS

Loans to principal officers, directors, and their affiliates in 2000 were as
follows:

(In Thousands of Dollars)

Beginning balance $20,684
New loans 21,923
Effect of changes in related parties (102)
Repayments (17,769)
------
Ending balance $24,736
======

Deposits from principal officers, directors, and their affiliates at year end
2000 and 1999 were $10,710,000 and $8,217,000.

Directors have deferred some of their fees for future payment, including
interest. Amounts deferred are expensed, and were $61,000, $63,000, and $62,000
for 2000, 1999, and 1998.


NOTE O - FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

Some financial instruments, such as loan commitments, credit lines, letters of
credit, and overdraft protection, are issued to meet customer financing needs.
These are agreements to provide credit or to support the credit of others, as
long as conditions established in the contract are met, and usually have
expiration dates. Commitments may expire without being used. Off balance sheet
risk to credit loss exists up to the face amount of these instruments, although
material losses are not anticipated. The same credit policies are used to make
such commitments as are used for loans, including obtaining collateral at
exercise of the commitment.

Financial instruments with off-balance-sheet risk were as follows at year end:

2000 1999
---- ----
(In Thousands of Dollars)
Fixed Rate Variable Rate Fixed Rate Variable Rate

Commitments to make loans
(at market rates) $6,830 $5,057 $5,411 $3,764
Unused lines of credit and
letters of credit $10,690 $53,652 $9,026 $49,998

Commitments to make loans are generally made for periods of 60 days or less. The
fixed rate loan commitments have interest rates ranging from 6.0% to 12.0% and
maturities ranging from 15 years to 30 years.


NOTE P - CONTINGENCIES

From time to time certain claims are made against the Company and its banking
subsidiaries in the normal course of business. There were no outstanding claims
considered by management to be material at December 31, 2000.


NOTE Q - DIVIDEND LIMITATION OF SUBSIDIARIES

The subsidiary banks are restricted in their ability to pay dividends to the
Company by regulatory requirements. At December 31, 2000, approximately
$11,646,000 of the subsidiaries' retained earnings is available for transfer in
the form of dividends without prior regulatory approval.


NOTE R - CAPITAL ADEQUACY

Banks and bank holding companies are subject to regulatory capital requirements
administered by federal banking agencies. Capital adequacy guidelines and,
additionally for banks, prompt corrective action regulations involve
quantitative measures of assets, liabilities, and certain off-balance-sheet
items calculated under regulatory accounting practices. Capital amounts and
classifications are also subject to qualitative judgments by regulators. Failure
to meet capital requirements can initiate regulatory action.

Prompt corrective action regulations provide five classifications: well
capitalized, adequately capitalized, undercapitalized, significantly
undercapitalized, and critically undercapitalized, although these terms are not
used to represent overall financial condition. If adequately capitalized,
regulatory approval is required to accept brokered deposits. If
undercapitalized, capital distributions are limited, as is asset growth and
expansion, and capital restoration plans are required.

Accrued interest payable (1,977) (1,977) (1,255) (1,255)

The methods and assumptions used to estimate fair value are described as
follows.

Carrying amount is the estimated fair value for cash and cash equivalents, short
term borrowings, Federal Home Loan Bank stock, accrued interest receivable and
payable, demand deposits, short term debt, and variable rate loans or deposits
that reprice frequently and fully. Security fair values are based on market
prices or dealer quotes, and if no such information is available, on the rate
and term of the security and information about the issuer. For fixed rate loans
or deposits and for variable rate loans or deposits with infrequent repricing or
repricing limits, fair value is based on discounted cash flows using current
market rates applied to the estimated life and credit risk. Fair values for
impaired loans are estimated using discounted cash flow analysis or underlying
collateral values. Fair value of loans held for sale is based on market quotes.
Fair value of debt is based on current rates for similar financing. The fair
value of off balance sheet items is based on the current fees or cost that would
be charged to enter into or terminate such arrangements. The fair value of off
balance sheet items were not material to the consolidated financial statements
at December 31, 2000 and 1999.
