PART I

Item 1.  Business.

Chemical Financial Corporation ("Chemical" or the "Corporation") is a multibank holding company registered under the Bank Holding Company Act of 1956, as amended, and incorporated in the State of Michigan. Chemical was organized under Michigan law in August 1973, and is headquartered in Midland, Michigan. Chemical was substantially inactive until June 30, 1974, when it acquired its lead subsidiary bank, Chemical Bank and Trust Company ("CB&T"), pursuant to a reorganization in which the former shareholders of CB&T became shareholders of Chemical.

In addition to the acquisition of CB&T, the Corporation acquired eighteen community banks and thirteen branch bank offices through December 31, 2002. The Corporation has consolidated these acquisitions into three commercial bank subsidiaries. At December 31, 2002, the Corporation's three subsidiary banks were as follows: CB&T, headquartered in Midland, Michigan; Chemical Bank Shoreline, headquartered in Benton Harbor, Michigan; and Chemical Bank West, headquartered in Grand Rapids, Michigan.

The Corporation directly owns three non-bank subsidiaries: CFC Data Corp, CFC Financial Services, Inc. and CFC Title Services, Inc.

CFC Data Corp provides data processing services to two of the Corporation's subsidiary banks and to outside customers. The data processing services provided to the Corporation's subsidiaries represented 92% of total revenue of the data processing subsidiary in 2002, 90% in 2001 and 89% in 2000.

CFC Financial Services, Inc. is an insurance agency that operates under the assumed names Chemical Financial Insurance Agency (a property and casualty insurance agency) and CFC Investment Centers (a provider of mutual funds and annuity products to customers). CFC Title Services, Inc. is an issuer of title insurance to buyers and sellers of residential and commercial mortgage properties, including those occurring due to loan refinancing.

At December 31, 2002, Chemical was the fourth largest bank holding company headquartered in Michigan, measured by total assets, and together with its subsidiaries employed a total of 1,412 full-time equivalent employees.

Chemical's business is concentrated in a single industry segment - commercial banking. Chemical's subsidiaries offer a full range of commercial banking and fiduciary services. These include accepting deposits, business and personal checking

accounts, savings and individual retirement accounts, time deposit instruments, electronically accessed banking products, residential and commercial real estate financing, commercial lending, consumer financing, debit cards, safe deposit box services, automated teller machines, access to insurance and investment products, money transfer services, corporate and personal trust services and other banking services.

The principal markets for these financial services are the communities within Michigan in which Chemical's subsidiaries are located and the areas surrounding these communities. As of December 31, 2002, Chemical and its subsidiaries served these markets through 129 banking offices and 2 loan production offices across 32 counties, all in the lower peninsula of Michigan. In addition to the full service banking offices, the subsidiary banks operated 137 automated teller machines, both on and off bank premises, as of December 31, 2002.

Chemical's largest and lead subsidiary bank is CB&T. CB&T represented 46% of total deposits and 38% of total loans of Chemical and its subsidiaries on a consolidated basis as of December 31, 2002. Chemical's bank subsidiaries' largest loan category is residential real estate mortgages. At December 31, 2002, residential real estate loans totaled $648 million, or 31.2% of consolidated total loans. Residential real estate loans declined $121 million, or 15.7%, during 2002 as historically low interest rates prompted customers to choose long-term fixed interest rate residential real estate products, which Chemical generally sells in the secondary market. Chemical originated approximately $501 million of residential mortgage loans during 2002 which were sold in the secondary mortgage market, compared to $342 million and $59 million in residential mortgage loans originated and sold during 2001 and 2000, respectively. The significant increase in the origination of long-term fixed interest rate loans over the past two years was attributable to the significant decline in residential mortgage interest rates and the resulting increase in the refinancing of existing residential mortgages.

The principal sources of revenues for Chemical are interest and fees on loans, which accounted for 63% of total revenues in 2002, 64% of total revenues in 2001, and 62% of total revenues in 2000. Interest on investment securities is also a significant source of revenue, accounting for 21% of total revenues in 2002 and 2001and 24% of total revenues in 2000. Chemical has no foreign loans, assets or activities. No material part of the business of Chemical or its subsidiaries is dependent upon a single customer or very few customers.

The business of banking is highly competitive. In addition to competition from other commercial banks, banks face significant competition from nonbank financial institutions. Savings associations and credit unions compete aggressively with commercial banks for deposits and loans, and credit unions and finance companies are particularly significant factors in the consumer loan market. Banks compete for deposits with a broad range of other types of investments, the most significant of which over the past few years have been mutual funds and annuities. Insurance companies and investment firms are also significant competitors for customer deposits. In response to this increased competition for customers' bank deposits, the Corporation's subsidiary banks, through CFC Investment Centers, offer a broad array of mutual funds, annuity products and market securities through alliances with BankMark and FutureShare Financial Services. In addition, the trust department of CB&T offers customers a variety of investm ent products and services. The principal methods of competition for financial services are price (interest rates paid on deposits, interest rates charged on borrowings and fees charged for services) and service (convenience and quality of services rendered to customers).

Banks and bank holding companies are extensively regulated. Chemical's subsidiary banks are all chartered by the State of Michigan and supervised and regulated by the Michigan Office of Financial and Insurance Services. CB&T is the only bank subsidiary of Chemical that is a member of the Federal Reserve System and supervised, examined and regulated by the Federal Reserve System. The other two state non-member banks are supervised, examined and regulated by the Federal Deposit Insurance Corporation ("FDIC"). Deposits of all three bank subsidiaries are insured by the FDIC to the extent provided by law. Chemical has elected to be regulated by the Board of Governors of the Federal Reserve System ("Federal Reserve Board") as a financial holding company under the Bank Holding Company Act of 1956.

State banks and bank holding companies are governed by both federal and state laws that significantly limit their business activities in a number of respects. Examples of such limitations include: (1) prior approval of the Federal Reserve Board, and in some cases various other governing agencies, is required for bank holding companies to acquire control of any additional bank holding companies, banks or branches, (2) the business activities of bank holding companies and their subsidiaries are limited to banking and to other activities which are determined by the Federal Reserve Board to be closely related to banking, and (3) transactions between bank holding company subsidiary banks are significantly restricted by banking laws and regulations. Somewhat broader activities are permitted for qualifying financial holding companies, such

as Chemical, and "financial subsidiaries." Chemical currently does not have any subsidiaries that have elected to qualify as "financial subsidiaries."

Chemical is a legal entity separate and distinct from its subsidiary banks and non-bank subsidiaries. Chemical's primary source of revenues results from dividends paid to it by its subsidiaries. Federal and state banking laws and regulations limit both the extent to which Chemical's subsidiary banks can lend or otherwise supply funds to Chemical or certain of its affiliates and also place certain restrictions on the amount of dividends the subsidiary banks of Chemical may pay to Chemical.

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, minimum capital requirements, 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 USA Patriot Act, electronic funds transfer laws, redlining laws, predatory lending laws, antitrust laws, environmental laws, anti-money laundering laws and privacy laws. These laws and regulations can have a significant effect on the operating results of banks.

The Gramm-Leach-Bliley Act of 1999 ("1999 Act") largely removed the restrictions that previously prevented affiliations among banks, securities firms, and insurance companies and provides for a system of functional regulation of the financial services industry. Among other provisions, the 1999 Act:

To recharacterize itself as a financial holding company and to avail itself of the broader powers permitted for financial holding companies, a bank holding company must meet certain regulatory standards for being "well capitalized," "well-managed" and "satisfactory" in its Community Reinvestment Act compliance. The Corporation became a financial holding company in 2000.

Under Federal law, the FDIC has the authority to impose special assessments on insured depository institutions to repay FDIC borrowings from the United States Treasury or other sources, and to establish semi-annual assessment rates on Bank Insurance Fund ("BIF") member banks, so as to maintain the BIF at the designated reserve ratio defined by law. The semi-annual assessment rate of the FDIC is based upon a system of risk-based premiums for deposit insurance, pursuant to which the premiums paid by a depository institution are based on the probability that the BIF will incur a loss in respect of such institution.

The recapitalization of the Savings Association Insurance Fund ("SAIF") was accomplished through the enactment of The Deposit Insurance Funds Act of 1996 (the "Funds Act") on September 30, 1996. This legislation authorized the Financing Corporation ("FICO") to impose periodic assessments on depository institutions that are members of the BIF, in addition to institutions that are members of the SAIF. The purpose of these periodic assessments is to spread the cost of the interest payments on the outstanding FICO bonds over a larger number of institutions. Until the change in the law, only SAIF-member institutions bore the cost of funding these interest payments. FDIC premiums, which consisted exclusively of the FICO assessment, were $.5 million in each of the three years ended December 31, 2002.

Federal law also contains a "cross-guarantee" provision that could result in insured depository institutions owned by Chemical being assessed for losses incurred by the FDIC in connection with assistance provided to, or the failure of, any other insured depository institution owned by Chemical. Under Federal Reserve Board policy, Chemical is expected to act as a source of financial strength to each subsidiary bank and to commit resources to support each subsidiary bank.

Banks are subject to the provisions of the Community Reinvestment Act of 1977 ("CRA"). Under the terms of the CRA, the appropriate federal bank regulatory agency is required, in connection with its examination of a bank, to assess such bank's record in meeting the credit needs of the community served by that bank, consistent with the safe and sound operation of the institution. The regulatory agency's assessment of the bank's record is made available to the public. Further, such assessment is required of any bank which has applied to: (1) obtain deposit insurance coverage for a newly chartered institution, (2) establish a new branch office that will accept deposits, (3) relocate an office, or (4) merge or consolidate with, or acquire the assets or assume the liabilities of, a federally regulated financial institution. In the case of a bank holding company applying for approval to acquire a bank or another bank holding company, the Federal Reserve Board will assess the CRA compliance record of each su bsidiary bank of the applicant bank holding company, and such compliance records may be the basis for denying the application.

Bank holding companies may acquire banks located in any state in the United States without regard to geographic restrictions or reciprocity requirements imposed by state law. Banks may establish interstate branch networks through acquisitions of other banks. The establishment of de novo interstate branches or the acquisition of individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) is allowed only if specifically authorized by state law.

Michigan 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 Michigan Office of Financial and Insurance Services, Division of Financial Institutions, (1) acquisition of Michigan banks by FDIC-insured banks, savings banks or savings and loan associations located in other states, (2) 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, (3) consolidation of Michigan banks and FDIC-insured banks, savings banks or savings and loan associations located in other states having laws permitting such consolidation, (4) 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 (5) es tablishment by foreign banks of branches located in Michigan.

Mergers, Acquisitions and Consolidations

The following is a summary of the business combinations completed during the three-year period ended December 31, 2002.

On September 14, 2001, the Corporation acquired Bank West Financial Corporation ("BWFC"). BWFC was the parent company of Bank West, a Michigan stock savings bank with five full-service branches and one loan production office in Kent and Ottawa counties in Michigan. The purchase added approximately $300 million in total assets, $232 million in total loans and $194 million in total deposits as of the date of acquisition, for which the Corporation paid a premium of $7.3 million.

Bank West was merged into the Corporation's existing subsidiary, Chemical Bank West. The Corporation exchanged $29.2 million in cash for all of the outstanding stock of BWFC.

On July 13, 2001, the Corporation acquired four branch banking offices from Fifth Third Bank and Old Kent Bank in Holland, Zeeland, Grand Haven and Fremont, Michigan. The purchase of the four branch banking offices added total deposits of approximately $144 million and total loans of $97 million as of the date of acquisition, for which the Corporation paid a premium of $15.3 million. The offices in Holland, Zeeland and Grand Haven are being operated as branches of Chemical Bank Shoreline, and Chemical Bank West is operating the office in Fremont.

The acquisitions of the four branches and BWFC in 2001 were accounted for by the purchase method of accounting; therefore, the financial results of these operations are included from their respective acquisition dates, with no restatement of prior period amounts.

On January 9, 2001, the Corporation merged with Shoreline Financial Corporation ("Shoreline"), a one-bank holding company headquartered in Benton Harbor, Michigan and parent company of Shoreline Bank. As of the effective date of the transaction, Shoreline had total assets of approximately $1.1 billion, total deposits of approximately $.8 billion and total loans of approximately $.8 billion. The Corporation is operating Shoreline Bank through a separate subsidiary of the Corporation, Chemical Bank Shoreline, with its headquarters in Benton Harbor. The Corporation issued approximately 8.2 million shares of common stock for all of the outstanding stock of Shoreline. The transaction was accounted for as a pooling of interests business combination and, therefore, all prior period amounts included in the consolidated financial statements were restated to include Shoreline as if it had always been part of the Corporation.

On December 31, 2000, the Corporation consolidated nine of its then ten subsidiary banks into two; Chemical Bank and Trust Company and Chemical Bank West. Chemical Bank South, headquartered in Marshall, Michigan remained a separate subsidiary until October 26, 2001 when it was consolidated into Chemical Bank Shoreline.

In conjunction with the merger with Shoreline and the internal consolidations, the Corporation recognized $9.2 million ($7.1 million on an after-tax basis) of merger and restructuring expenses during the first quarter of 2001. The term "net operating income" utilized in this report means net income before the impact of the after-tax $7.1 million of merger and restructuring expenses. Net operating income is a measure not defined under accounting principles generally accepted in the United States.

On March 24, 2000, the Corporation acquired two branch banking offices from Old Kent Bank located in Evart and Morrice, Michigan. The branches had total deposits of approximately $15 million and $10 million, respectively, as of that date, for which the Corporation paid a premium of approximately $1.7 million. The offices became branch offices of existing bank subsidiaries. The transaction was accounted for by the purchase method of accounting.

The nature of the business of Chemical's subsidiaries is such that they hold title to numerous parcels of real property. These properties are primarily owned for branch offices; however, Chemical and its subsidiaries may hold properties for other business purposes, as well as on a temporary basis for properties taken in, or in lieu of foreclosure, 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 clean up of contamination on or originating from those properties, even if they are wholly innocent of the actions that caused the contamination. These liabilities can be material and can exceed the value of the contaminated property.

The following table presents information regarding the equity compensation plans both approved and not approved by shareholders at December 31, 2002:

The 1997 plan was approved by the shareholders at the April 21, 1997 annual meeting of shareholders. At the April 20, 1992 annual meeting of shareholders, the shareholders voted to increase the authorized shares issuable under the 1987 plan by 100,000 shares and extend the plan to April 20, 1997. Key employees of the Corporation and its subsidiaries, as the Compensation Committee of the board of directors may select from time to time, are eligible to receive awards under the 1997 plan. No employee of the Corporation may receive any awards under the 1997 plan while the employee is a member

of the Compensation Committee. No new awards may be made under the 1987 plan or the Shoreline Plan. New awards for up to 418,904 shares may be made under the 1997 plan.

The plans (other than the Shoreline Plan) provide that the option price of incentive stock options awarded shall not be less than the fair market value of the Corporation's common stock on the date of grant. Historically, options granted under the plans are first exercisable from one to five years from the date of grant, at the discretion of the Compensation Committee, and expire not later than ten years and one day after the date of grant. Options granted may be designated nonqualified stock options or incentive stock options. Options granted may include stock appreciation rights that entitle the recipient to receive cash or a number of shares of common stock without payment to the Corporation that have a market value equal to the difference between the option price and the market price of the total number of shares awarded under the option at the time of exercise of the stock appreciation right. The plans provide, at the discretion of the Compensation Committee, that payment for exercise of an option ma y be made in the form of shares of the Corporation's common stock having a fair market value equal to the exercise price of the option at the time of exercise, or in cash. The plans also provide for the payment of the required tax withholding generated upon the exercise of a nonqualified stock option in the form of shares of the Corporation's common stock having a fair market value equal to the amount of the required tax withholding at the time of exercise, upon prior approval and at the discretion of the Compensation Committee. As of December 31, 2002, there were options outstanding under the Shoreline Plan for 17,884 shares of common stock with a weighted average exercise price of $19.45.

Equity compensation plans not approved by security holders consists of The Chemical Financial Corporation 2001 Stock Purchase Plan for Subsidiary and Community Bank Directors (the "Plan"), which became effective on March 25, 2002. The 1998 Stock Purchase Plan for Subsidiary Directors was terminated on March 25, 2002 and no shares were available for issuance under that plan at December 31, 2002. The Plan is designed to provide non-employee directors of the Corporation's subsidiaries and community banks, who are neither directors nor employees of the Corporation, the option of receiving their fees in the Corporation's stock. The Plan provides for a maximum of 75,000 shares of the Corporation's common stock, subject to adjustments for certain changes in the capital structure of the Corporation as defined in the Plan, to be available under the Plan. Subsidiary directors and community bank directors, who elect to participate in the Plan, may elect to contribute to the Plan fifty percent or one hundred percent of their board of director fees and/or fifty percent or one hundred percent of their director committee fees, earned as directors or community bank directors of the Corporation's subsidiaries. Contributions to the Plan are made by the Corporation's subsidiaries on behalf of each electing participant. Plan participants may terminate their participation in the Plan, at any time, by written notice of withdrawal to the Corporation. Participants will cease to be eligible to participate in the Plan when they cease to serve as directors or community bank directors of subsidiaries of the Corporation. Shares are distributed to participants annually.
