Item 1. Business.

General
         Citizens Banking Corporation ("Corporation") was organized January 1,
1982. It is a multibank holding company registered under the Bank Holding
Company Act of 1956, as amended, and is incorporated in the State of Michigan.
On December 31, 1997, the Corporation directly or indirectly owned two banking
subsidiaries and five nonbanking subsidiaries and had 1978 full-time equivalent
employees. Additional information related to the subsidiaries at year-end 1997
is provided below.




====================================================================================================================

====================================================================================================================


(1)  Consolidated totals of Citizens Bank include its wholly owned nonbank 
     subsidiaries, Citizens Commercial Leasing Corporation ("CCLC"); CB 
     Financial Services, Inc.; Citizens Bank Mortgage Corporation; Citizens
     Title Services, Inc. and Lakeshore Insurance Agency, Inc. (not active).
     All of the named subsidiaries are based in Flint, Michigan except for CCLC 
     which is based in Saginaw, Michigan.

         The Corporation's subsidiary banks are full service commercial banks
offering a variety of financial services to corporate, commercial, correspondent
and individual bank customers. These services include commercial, mortgage and
consumer lending, demand and time deposits, trust services, investment services,
safe deposit facilities, and other financial products and services. The bank
subsidiaries are wholly owned by the Corporation and operate through 128 banking
offices. The offices are located along the Interstate 75 corridor within the
State of Michigan from northern suburban Detroit to the greater Grayling/Gaylord
area as well as western suburban Detroit and central and southwestern Michigan.
         On July 1, 1997, the Corporation expanded its market presence in
Michigan due to the merger with CB Financial Corporation headquartered in
Jackson, Michigan. The merger resulted in an expanded presence in the greater
Jackson/Lansing markets and in northwestern Michigan with over thirty new
Citizens branch locations. As part of the merger, Citizens issued 6,256,355
shares of its common stock in a tax free exchange for all of the outstanding
shares of CB Financial Corporation. The merger was accounted for as a pooling of
interests resulting in the restatement of all financial information presented.
         Citizens Commercial Leasing Corporation, a wholly owned nonbank
subsidiary of Citizens Bank, engages in direct lease financing of office,
medical and other equipment, and participates in high quality indirect lease
participations.
         On December 29, 1994 the State of Michigan amended the State's Banking
Code of 1969 to allow banks to engage in the insurance business and to own an
insurance agency. Although the National Bank Holding Company Act prohibits the
holding company from direct ownership of an insurance agency, banks within the
holding company may now do so. During the second quarter of 1997, Citizens Bank
established a wholly owned subsidiary, called CB Financial Services, Inc.
Through this subsidiary, the Corporation sells life insurance and annuity
products to clients subject to certain restrictions.

         In the fourth quarter of 1997, Citizens Bank established a wholly owned
subsidiary, Citizens Bank Mortgage Corporation. The new Corporation originates
new mortgage loans to be held by the subsidiary or sold to the secondary market.
The new Corporation provides residential mortgage services similar to those
previously provided by Citizens Bank. Also in the fourth quarter of 1997,
Citizen Bank established a wholly owned subsidiary, Citizens Title Services,
Inc. This new subsidiary provides title insurance to buyers and sellers of
residential and commercial mortgage properties including those occurring due to
loan refinancing.

Competition
         The financial services industry is highly competitive. The banking
subsidiaries compete with other commercial banks, many of which are subsidiaries
of other bank holding companies, for loans, deposits, trust accounts and other
business on the basis of interest rates, fees, convenience and quality of
service. They also actively compete with a variety of other financial services
organizations including savings and loan associations, finance companies,
mortgage banking companies, brokerage firms, credit unions and other
organizations. Citizens Commercial Leasing Corporation competes directly with
other leasing companies. Citizens Title Services, Inc. competes directly with
other title insurance companies.
         Loans comprise 77.3% of the Corporation's average assets and are made
in the normal course of business to individuals, partnerships, municipalities
and corporations. Credit is extended to customers within the commercial,
commercial mortgage, real estate construction, real estate mortgage, consumer
and lease financing categories. Consumer loans are primarily composed of
automobile, personal, marine, home equity and bankcard loans and represent 38.2%
of the 1997 average loan portfolio. Consumer loans originated follow strict
Corporate credit underwriting procedures. Real estate mortgage loan extensions
are primarily first liens on one to four family structures and unless insured by
a private mortgage insurance company typically have traditional loan to
appraisal ratios of 80% or less. Commercial and commercial mortgage loan
originations generally do not rely on the performance of the real estate market
to generate funds for repayment and do not represent a concentration in any one
industry or company. Additional information on the composition of the loan
portfolio and the related nonperforming assets is incorporated herein by
reference from Exhibit 13 of this document on pages 11 to 13 under the captions
"Loans" and "Nonperforming Assets".
         Mergers between and the expansion of financial institutions both within
and outside of our primary markets of Michigan and Illinois have provided
significant competitive pressure in those markets. In addition, the passage of
federal interstate banking legislation has expanded the banking market and
heightened competitive forces. The affect of this legislation is further
discussed on page 5 under the caption "Supervision and Regulation".
         On June 1, 1996, the Corporation consolidated its six Michigan
chartered banks into one bank called Citizens Bank. The consolidation further
streamlined operations and reduced certain costs however, local management was
retained and the local boards of directors were retained as "community boards".
         Other factors such as employee relations and environmental laws also
impact the Corporation's competitiveness. Presently, none of the Corporation's
employees are covered by collective bargaining agreements and the Corporation
maintains a favorable relationship with it's employees. The impact of
environmental laws is further discussed in "Item 3. Legal Proceedings" of this
document.

Supervision and Regulation
         Citizens Banking Corporation is subject to supervision and regulation
by the Federal Reserve Board under the Bank Holding Company Act of 1956, as
amended (the "Act"). The Act requires the Corporation to provide notice or
obtain the prior approval of the Board of Governors of the Federal Reserve
System for bank and nonbank acquisitions and prescribes limitations on the
nonbanking activities of the Corporation. As a bank holding company, the
Corporation and its subsidiaries are able only to conduct the business of
banking and activities so closely related to banking or managing or controlling
banks as to be a proper incident thereto.
         The Corporation's subsidiary banks are subject to various regulatory
authorities. Citizens Bank is chartered by the State of Michigan and is subject
to supervision, regulation and examination by the Financial Institutions Bureau
of the State of Michigan as well as the Federal Reserve Board. Citizens Bank -
Illinois, N.A. is chartered under federal law and is subject to supervision,
regulation and examination by the Comptroller of the Currency. Both banks are
subject to supervision and examination by the Federal Deposit Insurance
Corporation ("FDIC"), as their deposits are insured by the FDIC to the extent
provided by the law. In addition, both banks are members of the Federal Reserve
System. The Corporation's nonbank companies are supervised and examined by the
Federal Reserve System.
         Certain regulatory matters concerning capital adequacy guidelines for
the Corporation and its banking subsidiaries, limitations on the payment of
dividends to the Corporation by its banking subsidiaries and maintenance of
minimum average reserve balances by the banking subsidiaries with the Federal
Reserve Bank are incorporated herein by reference from Exhibit 13 of this
document on pages 16 through 17 and 36 through 37 under the captions, "Liquidity
and Debt Capacity" and "Note 16. Regulatory Matters", respectively.
         The 1994 passage of the federal Riegle-Neal Interstate Banking and
Branching Efficiency Act allows states the ability to enact legislation
permitting interstate branching but have no choice in opting out of provisions
related to interstate banking. The effect of the interstate banking provisions
do not impact Michigan or neighboring states since these states have previously
passed legislation allowing bank holding companies to own bank affiliates in
multiple states. On November 29, 1995 the Michigan legislature passed Public Act
202 permitting interstate branching. This law allows a bank the ability to
establish branches outside of the State of Michigan provided that state adopts
similar legislation. However, since Citizens is headquartered in Michigan and
currently has only one subsidiary outside of the state this does not
significantly affect the Corporation. The Corporation may be impacted as states
adjacent to Michigan pass similar legislation. The impact of this is not
expected to significantly affect the Corporation's strategic plan, except to
allow potentially greater consolidation benefits if the Corporation acquires
banks outside of Michigan.
         The Financial Institutions Reform, Recovery, and Enforcement Act of
1989 ("FIRREA") adopted in August 1989 significantly affected financial
institutions. Key provisions of FIRREA provided for the acquisition of thrift
institutions by bank holding companies (previously only failing thrifts were
permitted to be acquired), increased deposit insurance assessments for insured
banks, redefined applicable capital standards for banks and thrifts, broadened
the enforcement power of federal bank regulatory agencies, and required that any
FDIC-insured depository institution be held liable for any loss incurred by the
FDIC in connection with the default of any commonly controlled FDIC-insured
depository institution or any assistance provided by the FDIC to any such
institution in danger of default.
         The Federal Deposit Insurance Corporation Improvement Act of 1991
("FDICIA"), signed into law on December 19, 1991, imposed on banks relatively
detailed standards and


                                       5

   6


mandated the development of additional regulations governing nearly every aspect
of the operations and management of banks, in addition to many aspects of bank
holding companies. Some of the major provisions contained in FDICIA includes
recapitalization of the Bank Insurance Fund ("BIF"), a risk-based insurance
premium assessment system, a capital-based supervision system that links
supervisory intervention to the deterioration of a bank's capital level, new
auditing and accounting and examination requirements, and mandated standards for
bank lending and operation.
         FDICIA provides the FDIC with the authority to impose assessments on
insured BIF member depository institutions to maintain the fund at the
designated reserve ratio defined in FDICIA. In response to the BIF attaining the
designated reserve ratio in 1995, FDIC assessments were effectively eliminated
in 1996 for banks meeting the requirements of supervisory risk subgroup 1.A.
"well capitalized". Both of the Corporation's subsidiaries have sufficient
capital to maintain this designation (the FDIC's highest rating). In 1998, banks
maintaining the "well capitalized" designation will again have no FDIC insurance
premium requirements except for a special assessment of 1.3 cents per 100
dollars of deposits. This special assessment resulted from the September 30,
1996 passage of Deposit Insurance Funds Act of 1996 by Congress and applies to
all commercial banks regardless of risk subgroup classification. Further
regulatory changes could impact the amount and type of assessments paid by the
Corporation's subsidiary banks.

Monetary Policy
         The monetary and fiscal policies of regulatory authorities, including
the Federal Reserve System, strongly influence the banking industry. Through
open market securities transactions, variations in the discount rate and the
establishment of reserve requirements, the Board of Governors of the Federal
Reserve System exerts considerable influence on interest rates and the supply of
money and credit. The effect of these measures on future business and earnings
of the Corporation cannot be predicted.

Environmental Matters
         The Corporation's primary exposure to environmental risk is through its
provision of trust services and its lending activities. In each instance, the
Corporation has policies and procedures in place to mitigate its environmental
risk exposures. With respect to lending activities, environmental site
assessments at the time of loan origination are mandated by the Corporation to
confirm collateral quality as to commercial real estate parcels posing higher
than normal potential for environmental impact, as determined by reference to
present and past uses of the subject property and adjacent sites. Environmental
assessments are also mandated prior to any foreclosure activity involving
non-residential real estate collateral. In the case of trust services, the
Corporation utilizes various types of environmental transaction screening to
identify actual and potential risks arising from any proposed holding of
non-residential real estate for trust accounts. Consequently the Corporation
does not anticipate any material effect on capital expenditures, earnings or the
competitive position of itself or any of its subsidiaries with regard to
compliance with federal, state or local environmental protection laws or
regulations. Additional information is provided in the "Item 3. Legal
Proceedings" section of this document.

ITEM 2. PROPERTIES.

         The Corporation's offices are located at One Citizens Banking Center,
328 South Saginaw Street, Flint, Michigan in the main office building of
Citizens Bank, its largest bank subsidiary. The Corporation's subsidiaries
operate through 131 banking offices. Of these, 40 are leased and the remaining
are owned. Rent expense on the leased properties totaled $1,889,067 in 1997. 
         The banking offices are located in various communities throughout the
State of Michigan and in the Chicago suburbs of Berwyn, Cicero and Elk Grove,
Illinois. At certain Citizens Bank locations a portion of the office buildings
are leased to tenants.
         Additional information related to the property and equipment owned or
leased by the Corporation and its subsidiaries is incorporated herein by
reference from Exhibit 13 on page 29 under the caption "Note 7. Premises and
Equipment" of this document.

ITEM 3. LEGAL PROCEEDINGS.

         The Corporation and its subsidiaries are parties to a number of
lawsuits incidental to its business. Although litigation is subject to many
uncertainties and the ultimate exposure with respect to many of these matters
cannot be ascertained, management does not believe the ultimate outcome of these
matters will have a materially adverse effect on the financial condition or the
liquidity of the Corporation.
         From time to time, certain of the Corporation's subsidiaries are
notified by applicable environmental regulatory agencies, pursuant to State or
Federal environmental statutes or regulations, that they may be potentially
responsible parties ("PRPs") for environmental contamination on or emanating
from properties currently or formerly owned. Typically, exact costs of
remediating the contamination cannot be fully determined at the time of initial
notification. While, as PRPs, these subsidiaries are potentially liable for the
costs of remediation, in most cases, a number of other PRPs have been identified
as being jointly and severally liable for remediation costs. Additionally, in
certain cases, statutory defenses to liability for remediation costs may be
asserted based on the subsidiaries' status as lending institutions that acquired
ownership of the contaminated property through foreclosure. The Corporation's
management is not presently aware of any environmental liabilities which pose a
reasonable possibility of future material impact on the Corporation or its
earnings. It is the Corporation's policy to establish and accrue appropriate
reserves for all such identified exposures during the accounting period in which
a loss is deemed to be probable and the amount is determinable.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

         No matters were submitted during the fourth quarter of 1997 to a vote
of security holders through the solicitation of proxies or otherwise.
