Notes to Consolidated Financial Statements

Note 1.     Basis of presentation
            The accompanying unaudited consolidated financial statements have
            been prepared in accordance with generally accepted accounting
            principles for interim financial information and the instructions
            for Form - 10Q and Article 9 of Regulation S-X. Accordingly, they do
            not include all of the information and notes required by generally
            accepted accounting principles for complete financial statements. In
            the opinion of management, all adjustments (consisting of normal
            recurring accruals) considered necessary for a fair presentation
            have been included. Operating results for the three months ended
            March 31, 1999 are not necessarily indicative of the results that
            may be expected for the year ended December 31, 1999.

Note 2.     Reclassifications
            Certain prior year amounts have been reclassified to conform to the
            current year financial statement presentation.

Note 3.     During the first quarter of 1998 the Corporation adopted the
            Statement of Financial Accounting Standards (SFAS) No. 130
            "Reporting Comprehensive Income". The statement requires that
            entities present items of other comprehensive income in a financial
            statement with the same prominence as other financial statements.
            This statement requires reclassification of financial statements for
            earlier periods for comparative purposes.

            The adoption for SFAS No. 130 does not effect the net income of the 
            Corporation.

Results of Operations

Table 1 summarizes selected financial data for the three months ended March 31,
1999 and 1998. As indicated earnings for the three months ended March 31, 1999
were $886,000 compared to $820,000 for the same period in 1998. Earnings have
continued to steadily increase as a result of continued strength of core banking
activities. Contributing to the 1999 results was the improvement of net interest
income and other operating income.

The banking industry uses standard performance indicators to help evaluate the
Corporation's performance. Return on average assets is one of these indicators.
For the three months ended March 31, 1999 the Corporation's return on average
assets was 1.32% compared to 1.28% for the same period in 1998. Total assets
increased approximately $5,000,000 from March 31, 1998 to $266,448,000 at March
31, 1999. Stockholders' Equity increased approximately $3,000,000 from March 31,
1998 to $30,565,000 at March 31, 1999. The increase in equity will allow the
Corporation to continue its growth strategy. Net income per share-basic was $.63
in the first three months of 1999 compared to $.59 for the same period in 1998.

Net Interest Income

Net interest income and average balances and yields on major categories of

As indicated in Table 2, during the three months ended March 31, 1999, net
interest income increased over the same period in 1998 principally due to the
reduction of rates paid on interest bearing liabilities.


<PAGE>   11

Net interest income (displayed without consideration of full tax equivalency),
average balance sheet amounts, and the corresponding yields for the three months
ended March 31, 1999 and 1998 are shown in Table 3. Net interest income for the
three months ended March 31, 1999 was 3,128,000 an increase of $40,000 over the
same period in 1998. This represents an increase of 1.3%. The primary factor
contributing to the net interest income increase is the reduction of interest
expense due to lower rates paid on savings, interest bearing DDA, and time
deposits. Also indicated in Table 3, for the three months ended March 31, 1998
net interest income was $3,088,000. This is an increase of $55,000 or 1.8% over
the same period in 1997. The increase in 1998 is also attributable to the
reduction of interest expense due to lower rates paid on interest bearing
deposits and a reduction in time deposits of $100,000 and over.

Management continually monitors the Corporation's balance sheet to insulate net
interest income from significant swings caused by interest rate volatility. If
market rates continue to change in 1999, additional corresponding changes in
funding costs will be considered to avoid any potential negative impact on net
interest income. The Corporation's policies in this regard are further discussed
in the section titled "Interest Rate Risk".

ALLOWANCE AND PROVISION FOR LOAN LOSSES

The allowance for loan losses (ALL) reflects management's judgment as to the
level considered appropriate to absorb potential losses inherent in the loan
portfolio. Fentura's subsidiary, The State Bank's, methodology in determining
the adequacy of the ALL includes a review of individual loans and off-balance
sheet arrangements, historical loss experience, current economic conditions,
portfolio trends, and other pertinent factors. Although reserves have been
allocated to various portfolio segments, the ALL is general in nature and is
available for the portfolio in its entirety. At March 31, 1999, the ALL was
$2,850,000, or 1.64% of total loans, including those loans held for sale. This
compares with $3,012,000, or 1.64%, at March 31, 1998. The decline in the ALL
balance was a result of a substantial write down on a nonperforming commercial
loan in 1998. The loss was a result of isolated circumstances and management
believes that overall asset quality remains strong.

The provision for loan losses was $195,000 for the three months ended March 31,
1999 and $156,000 for the same period in 1998. The primary reason for increasing
the provision in 1999 was to maintain the ALL balance commensurate with expected
loan growth.

Non-interest income increased in the three months ended March 31, 1999 as
compared to the same period in 1998, due to an increase in service charges on
deposit accounts. Overall non-interest income was $1,026,000 in the three months
ended March 31, 1999 compared to $960,000 for the same period in 1998. These
figures represent an increase of 6.9%. Table 5 provides a more detailed
breakdown of the components of non-interest income than can be found in the
income statement on page 5.

The most significant category of non-interest income is service charges on
deposit accounts. These fees were $476,000 in the three months ended March 31,
1999 compared to $415,000 for the same period of 1998. This represents an
increase of 14.7%. Growth in deposit totals, the number of accounts and certain
account activities account for the increases in fees.

Gains on the sale of mortgage loans originated by the bank and sold in the
secondary market were $52,000 in the quarter ended March 31, 1999 and $74,000 in
the same period in 1998. The decrease occurred because of a decrease in
residential mortgage refinance activity and new loan volumes.

Mortgage servicing fees were $76,000 in the three months ended March 31, 1999
compared to $94,000 in the same time period in 1998. This is a decline of
$18,000 or 19.1%. The decline is attributable to lower serviced loan balances in
1999 due to payoffs throughout 1998 and the first three months of 1999 of
serviced loans and the Corporation's retention of certain new mortgages as
opposed to selling those loans and recognizing servicing fees.

Fiduciary income increased $14,000 in the three months ended March 31, 1999
comparing to the same time period in the prior year. This 9.9% increase in fees
is attributed to growth in the assets under management within the Corporation's
Investment Trust Department.

Gains on the sale of investments were $26,000 in the first quarter of 1999.
These gains occurred from sales of investments which had lower yield potential
and longer maturities in connection with forecasts relating to yield curve
movements and the expected impact on market rates. Proceeds from these
transactions are being used to invest in other securities with stronger yields
within certain maturity horizons. In the first quarter of 1998 there were no
such transactions and accordingly there were no gains from the sale of
investments.

</TABLE>

Total non-interest expense was $2,675,000 in the three months ended March 31,
1999 compared with $2,700,000 in the same period of 1998. This is a decrease of
 .9%. This decrease occurred due to decreases in office supplies, loan and
collection, advertising, and other operating expenses.

Salary and benefit costs, Fentura's largest non-interest expense category, were
$1,328,000 in the three months ended March 31, 1999, compared with $1,239,000,
or an increase of 7.2%, for the same time period in 1998. Increased costs are
primarily a result of an increase in the number of employees and normal annual
salary increases.


<PAGE>   15

During the three months ended March 31, 1999 equipment expenses were $341,000
compared to $316,000 for the same period in 1998, an increase of 7.9%. The
increase in expense is attributable to equipment repairs, upgrades, and
maintenance.

Occupancy expenses at $193,000 increased in the three months ended March 31,
1999 comparing to the same period in 1998 by $16,000 or 9.0%. The increase is
attributable to increases in facility repairs and maintenance, utility, real
estate tax, and facility depreciation expense.

During the three months ended March 31, 1999 office supplies expense at $65,000
decreased $23,000 comparing to the $88,000 in expense for the same period in
1998. This decrease is attributable to volume decreases of regular office
supplies and preprinted forms in 1999.

Loan and collection expenses, at $60,000, were down $51,000 during the three
months ended March 31, 1999 comparing to the same time period in 1998. This
decrease is primarily attributable to decreases in home equity loan fees waived
to the customer and paid by the bank and a decrease in dealer service fees paid
in connection with indirect auto lending.

Advertising expenses were $52,000 in the quarter ended March 31, 1999 compared
to $81,000 in the same period of 1998. This is a decrease of $29,000 or 35.8%.
Media and promotional advertising expenses in connection with the Bank's 100th
anniversary in 1998 account for the variance to 1999 expense.

Other operating expenses were $629,000 in the three months ended March 31, 1999
compared to $681,000 in the same time period in 1998, a decrease of $52,000 or
7.6%. The decrease is attributable to a decrease in deposit account losses.
These losses were down in 1999 because of a loss of $75,000 on an improperly
endorsed check in January of 1998.

NONPERFORMING ASSETS

Non-performing assets include loans on which interest accruals have ceased,
loans which have been renegotiated, and real estate acquired through
foreclosure. Past due loans are loans which were delinquent 90 days or more, but
have not been placed on non-accrual status. Table 7 represents the levels of
these assets at March 31, 1999 and 1998.

Non-performing loans include several delinquent single-family mortgage loans
which have sufficient equity and no expected loss. Non-accrual loans include a
large commercial loan and a residential construction mortgage loan. An agreement
has been executed that requires specific action plans, collateral pledges, and
related performance expectations for the commercial loan creating the largest
exposure for the Corporation. These loans will be closely monitored.

LIQUIDITY AND INTEREST RATE RISK MANAGEMENT

Asset/Liability management procedures are designed to assure liquidity and
reduce interest rate risks. The goal in managing interest rate risk is to
maintain a strong and relatively stable net interest margin. It is the
responsibility of the Asset/Liability Management Committee (ALCO) to set policy
guidelines and to establish short-term and long-term strategies with respect to
interest rate exposure and liquidity. ALCO, which is comprised of key members of
management, meets regularly to review Fentura's financial performance and
soundness, including interest rate risk and liquidity exposure in relation to
present and perspective markets, business conditions, and product lines.
Accordingly, the committee adopts funding and balance sheet management
strategies that are intended to determine that earnings, liquidity, and growth
rates are consistent with policy and prudent business standards.

Liquidity maintenance together with a solid capital base and strong earnings
performance are key objectives of the Corporation. The Bank's liquidity is
derived from a strong deposit base comprised of individual and business
deposits. Deposit accounts of customers in the mature market represent a
substantial portion of deposits of individuals. The Bank's deposit base plus
other funding sources (federal funds purchased, other liabilities and
shareholders' equity) provided primarily all funding needs in the first three
months of 1999 and 1998.

Primary liquidity is provided through short-term investments or borrowings
(including federal funds sold and purchased) and secondary liquidity is provided
by the investment portfolio. As of March 30, 1999 federal funds sold represented
2.9% of total assets, compared to 3.6% at March 30, 


<PAGE>   17

1998. The Corporation regularly monitors liquidity to ensure adequate cash
flows to cover unanticipated reductions in the availability of funding sources.

Interest rate risk is managed by controlling and limiting the level of earnings
volatility arising from rate movements. The Corporation regularly performs
reviews and analysis of those factors impacting interest rate risk. Factors
include maturity and re-pricing frequency of balance sheet components, impact of
rate changes on interest margin and prepayment speeds, market value impacts of
rate changes, and other issues. Both actual and projected performance is
reviewed, analyzed, and compared to policy and objectives to assure present and
future financial viability.

As indicated in the statement of cash flows, cash flows from financing
activities decreased $8,862,000 in first three months of 1999 due to the decline
of total deposits. Comparatively, in the first three months of 1998, cash flows
from financing activities decreased $1,937,000 because of decreases in time
deposits. Cash flows from investing activities were $10,606,000 during the first
three months of 1999 and $8,552,000 in the same period of 1998. The primary
reason for the increase in investing activities at the end of the first quarter
of 1999, was an increase in maturing investments comparing to the same period in
1998.

CAPITAL MANAGEMENT

Total shareholders' equity rose 10.9% to $30,565,000 at March 31, 1999 compared
with $27,552,000 at March 31, 1998. The Company's equity to asset ratio was
11.5% at March 31, 1999 and 10.5% at March 31, 1998. The increase in the amount
of capital was obtained through retained earnings and the proceeds from the
issuance of new shares. In the first three months of 1999, the Corporation
increased its cash dividends by 9.5% to $.23 per share compared with $.21 in the
same time period in 1998.

As indicated on the balance sheet on page 4, at March 31, 1998 the Company had
an unrealized gain on securities available for sale (AFS) of $3,000 compared to
an unrealized gain at March 31, 1998 of $115,000. This decrease in gain position
is attributable to market interest rates and the interest rate structures on
those securities held in the AFS portfolio.

REGULATORY CAPITAL REQUIREMENTS

Bank holding companies and their bank subsidiaries are required by banking
industry regulators to meet certain levels of capital adequacy. These are
expressed in the form of certain ratios. Capital is separated into two levels,
Tier I capital (essentially total common stockholders' equity less goodwill) and
Tier II capital (essentially the reserve for loan losses limited to 1.25% of
gross risk-weighted assets). These ratios are based on the degree of credit risk
in the Corporation's assets. All assets and off-balance sheet items such as
outstanding loan commitments are assigned risk factors to create an overall risk
weighted asset total. Capital levels are then measured as a percentage of total
risk weighted assets. The regulatory minimum for Tier I capital to risk weighted
assets is 4% and the minimum for Total capital (Tier I plus Tier II) to risk
weighted assets is 8%. The Tier I leverage ratio measures Tier I capital to
average assets and must be a minimum of 4%.

The FDIC has adopted a risk-based insurance premium system based in part on a
corporation's capital adequacy. Under this system a depository institution is
classified as well capitalized, adequately capitalized, or undercapitalized
according to its regulatory capital levels. Subsequently, a financial
institution's premium levels are based on these classifications and its
regulatory supervisory rating (the higher the classification the lower the
premium). It is the Corporation's goal to maintain capital levels sufficient to
receive a designation of "well capitalized".

INTEREST RATE SENSITIVITY MANAGEMENT

Interest rate sensitivity management seeks to maximize net interest income as a
result of changing interest rates, within prudent ranges of risk. The
Corporation attempts to accomplish this objective by structuring the balance
sheet so that re-pricing opportunities exist for both assets and liabilities in
roughly equivalent amounts at approximately the same time intervals. Imbalances
in these re-pricing opportunities at any point in time constitute a bank's
interest rate sensitivity. As a matter of practice, the Bank doesn't use
derivative transactions in managing interest rate risk.

An indicator of the interest rate sensitivity structure of a financial
institution's balance sheet is the difference between rate sensitive assets and
rate sensitive liabilities, and is referred to as "GAP".

Table 9 sets forth the distribution of re-pricing of the Corporation's earning
assets and interest bearing liabilities as of March 31, 1998, the interest rate
sensitivity GAP, as defined above, the cumulative interest rate sensitivity GAP,
the interest rate sensitivity GAP ratio (i.e. interest rate sensitive assets
divided by interest rate sensitive liabilities) and the cumulative sensitivity
GAP ratio. The table also sets forth the time periods in which earning assets
and liabilities will mature or may re-price in accordance with their contractual
terms. However, the table does not necessarily indicate the impact of general
interest rate movements on the net interest margin since the re-pricing of
various categories of assets and liabilities is subject to the Corporation's
needs, competitive pressures, and the needs of the Corporation's customers. In
addition, various assets and liabilities indicated as re-pricing within the same
period may in fact re-price at different times within such period and at
different rates or indices.

IMPACT OF YEAR 2000

The Year 2000 issue is the result of computer programs which were designed to
utilize two digits rather than four digits in date fields for computer
calculations. Any computer or electronic calculation recognizing a two digit
rather than a four digit date may incur system failure or miscalculate
information when using a date after December 31, 1999 resulting in potentially
serious impairment to business operations. The Corporation began addressing the
Year 2000 issue internally in 1997 with the formation of a task force created to
identify, coordinate, manage and monitor the impact of Year 2000 related issues.
The task force consists of representatives from every functional area of the
Corporation.

The Corporation's Year 2000 Program initially focused on technology assessment
and planning, and the upgrading or renovation of internal systems. Once the
assessment and renovation phases were largely complete the task force focused on
testing or validating internal systems and the assessment of external business
risk and contingency planning.

Currently, the Corporation's Year 2000 Program is tracked against a well defined
set of goals and key dates. The Corporation has not identified any noncompliant
systems for which a solution is not available and which would impair the
business operations. All Year 2000 costs to date have not been material and are
being expensed, or capitalized if it is a system replacement, as incurred.
Anticipated future expenses are not expected to materially impair future
earnings. The Corporation anticipates that all renovation or replacement and
testing procedures will be completed by June 30, 1999. As of December 31, 1998,
substantially all core system software applications were remediated. The
majority of internal testing of these software applications was complete.
Completion of the goals as of December 31, 1998, exceeds the milestones
established by the Corporation's banking regulators.

Throughout 1999, the task force will continue to assess and create contingency
plans as they relate to internal operational risk as well as external risks
including major customer and vendor due diligence. In its normal course of
business, the Corporation manages many types of risk. Management recognizes that
the risks presented by Year 2000 are unique given the pervasive nature of the
problem and the fact that there may be a higher likelihood the Year 2000 risk
will present itself in multiple, simultaneous impacts. Because of this, the
Corporation has adjusted and will continue to adjust its risk management
processes and contingency plans to take the most probable anticipated Year 2000
effects into account. Although it is too early to predict accurately what system
failures may occur, management believes sufficient planning, communication,
coordination, and testing will mitigate potential material disruption. In this
regard, contingency plans including command centers, response teams, technology
teams, and testing are being developed. In addition to the internal and external
testing, and credit assessments, the Corporation is assessing operational and
liquidity needs to enhance contingency plans.

While the Corporation is not aware of any Year 2000 problems for which a
solution is not available, other unanticipated Year 2000 issues could arise, and
there can be no assurance that actual results will be comparable to expected
results.
