             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1. BASIS OF PRESENTATION AND ACCOUNTING POLICIES

The unaudited consolidated financial statements include the accounts of MBT
Financial Corp. (the "Corporation") and its subsidiary, Monroe Bank & Trust (the
"Bank"). The Bank includes the accounts of its wholly owned subsidiaries, MBT
Credit Company, Inc. and MB&T Financial Services, Inc. The Bank operates
twenty-one branches in Monroe County, Michigan and four branches in Wayne
County, Michigan. MBT Credit Company, Inc. operates a mortgage loan office in
Monroe County. The Bank's primary source of revenue is from providing loans to
customers, who are predominantly small and middle-market businesses and
middle-income individuals. The Corporation's sole business segment is community
banking.

The accounting and reporting policies of the Bank conform to practice within the
banking industry and are in accordance with accounting principles generally
accepted in the United States. 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 reporting period. Actual results could differ from those estimates.
Material estimates that are particularly susceptible to significant changes in
the near term are the determination of the allowance for loan losses and the
valuation of other real estate owned.

The accompanying unaudited consolidated financial statements of the Corporation
have been prepared in accordance with the instructions to Form 10-Q.
Accordingly, they do not include all of the information and footnotes required
by generally accepted accounting principles for complete financial statements.
However, such information reflects all adjustments (consisting of normal
recurring adjustments), which are, in the opinion of Management, necessary for
fair statement of results for the interim periods.

The significant accounting policies are as follows:

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Corporation
and its subsidiary. All material intercompany transactions and balances have
been eliminated. Certain prior period amounts have been reclassified to conform
to the current period presentation.

COMPREHENSIVE INCOME

Accounting principles generally require that revenue, expenses, gains, and
losses be included in net income. Certain changes in assets and liabilities,
however, such as unrealized gains and losses on securities available for sale,
are reported as a separate component of the equity section of the balance sheet.
Such items, along with net income, are components of comprehensive income.

BUSINESS SEGMENTS

While the Corporation'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 Corporation's
operations are considered by management to be aggregated in one reportable
segment.

STOCK-BASED COMPENSATION

The Company applies the provisions of APB Opinion No. 25, "Accounting for
Stock-Based Compensation," for all employee stock option grants and has elected
to disclose pro forma net income and earnings per share amounts as if the
fair-value based method has been applied in measuring compensation costs.

</TABLE>

Compensation expense in the pro forma disclosures is not indicative of future
amounts, as options vest over several years and additional grants are generally
made each year.

The weighted average fair value of options granted was $5.38 in 2005 and $3.84
in 2004. The fair value of each option grant is estimated on the date of grant
using the Black-Scholes option-pricing model with the following assumptions used
for grants: expected option lives of seven years for both years; expected
volatility of 20.8% in 2005 and 25.3% in 2004; and risk-free interest rates of
3.8% in 2005 and 2004.

2. EARNINGS PER SHARE

3. LOANS

The Bank grants commercial, consumer, and mortgage loans primarily to customers
in Monroe County, Michigan, southern Wayne County, Michigan, and surrounding
areas. Although the Bank has a diversified loan portfolio, a substantial portion
of its debtors' ability to honor their contracts is dependent on the automotive,
manufacturing, and real estate development economic sectors.

Loans consist of the following (000s omitted):

Loans are placed in a nonaccrual status when, in the opinion of Management, the
collection of additional interest is doubtful. All loans internally classified
by Management as nonperforming are reviewed for impairment. Allowances for loans
determined to be impaired are included in the allowance for loan losses. All
cash received on nonaccrual loans is applied to the principal balance.
Nonperforming assets consist of nonaccrual loans, loans 90 days or more past
due, restructured loans, real estate that has been acquired in full or partial
satisfaction of loan obligations or upon foreclosure, and investment securities
that are 90 days or more past due on the interest or principal payments.

</TABLE>

For each period, the provision for loan losses in the income statement results
from the combination of an estimate by Management of loan losses that occurred
during the current period and the ongoing adjustment of prior estimates of
losses occurring in prior periods.

To serve as a basis for making this provision, the Bank maintains an extensive
credit risk monitoring process that considers several factors including: current
economic conditions affecting the Bank's customers, the payment performance of
individual loans and pools of homogeneous loans, portfolio seasoning, changes in
collateral values, and detailed reviews of specific loan relationships. For
loans deemed to be impaired due to an expectation that all contractual payments
will probably not be received, impairment is measured by comparing the Bank's
recorded investment in the loan to the present value of expected cash flows
discounted at the loan's effective interest rate, or the fair value of the
collateral, or the loan's observable market price.

                                   (CONTINUED)

The provision for loan losses increases the allowance for loan losses, a
valuation account which is netted against loans on the consolidated statements
of condition. As the specific customer and amount of a loan loss is confirmed by
gathering additional information, taking collateral in full or partial
settlement of the loan, bankruptcy of the borrower, etc., the loan is charged
off, reducing the allowance for loan losses. If, subsequent to a charge off, the
Bank is able to collect additional amounts from the customer or sell collateral
worth more than earlier estimated, a recovery is recorded.

6. FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET RISK

The Bank is a party to financial instruments with off-balance sheet risk in the
normal course of business to meet the financing needs of its customers. These
financial instruments include commitments to extend credit and standby letters
of credit. Those instruments involve, to varying degrees, elements of credit and
interest rate risk in excess of the amount recognized in the consolidated
statements of condition.

The Bank's exposure to credit loss in the event of nonperformance by the other
party to the financial instrument for commitments to extend credit and standby
letters of credit is represented by the contractual amount of those instruments.
The Bank uses the same credit policies in making commitments and conditional
obligations as it does for its other lending activities.

Standby letters of credit and financial guarantees written        15,929         16,449
</TABLE>

Commitments to extend credit are agreements to lend to a customer as long as
there is no violation of any condition established in the contract. Most
commercial lines of credit are secured by real estate mortgages or other
collateral, and generally have fixed expiration dates or other termination
clauses. Since the lines of credit may expire without being drawn upon, the
total committed amounts do not necessarily represent future cash requirements.
Credit card lines of credit have various established expiration dates, but are
fundable on demand. Home equity lines of credit are secured by real estate
mortgages, a majority of which have ten year expiration dates, but are fundable
on demand. The Bank evaluates each customer's creditworthiness on a case-by-case
basis. The amount of the collateral obtained, if deemed necessary by the Bank
upon extension of credit, is based on Management's credit evaluation of the
counterparty.

Standby letters of credit written are conditional commitments issued by the Bank
to guarantee the performance of a customer to a third party. Those guarantees
are primarily issued to support public and private borrowing arrangements and
other business transactions.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS

Certain statements contained herein are not based on historical facts and are
"forward-looking statements" within the meaning of Section 21A of the Securities
Exchange Act of 1934. Forward-looking statements which are based on various
assumptions (some of which are beyond the Corporation's control), may be
identified by reference to a future period or periods, or by the use of
forward-looking terminology, such as "may," "will," "believe," "expect,"
"estimate," "anticipate," "continue," or similar terms or variations on those
terms, or the negative of these terms. Actual results could differ materially
from those set forth in forward-looking statements, due to a variety of factors,
including, but not limited to, those related to the economic environment,
particularly in the market areas in which the company operates, competitive
products and pricing, fiscal and monetary policies of the U.S. Government,
changes in government regulations affecting financial institutions, including
regulatory fees and capital requirements, changes in prevailing interest rates,
acquisitions and the integration of acquired businesses, credit risk management,
asset/liability management, the financial and securities markets and the
availability of and costs associated with sources of liquidity.

The Corporation does not undertake, and specifically disclaims any obligation,
to publicly release the result of any revisions which may be made to any
forward-looking statements to reflect the occurrence of anticipated or
unanticipated events or circumstances after the date of such statements.

                               FINANCIAL CONDITION

During the first quarter of 2005, the Bank's deposits and assets decreased
slightly. The Bank is the depository for several municipalities which collect
taxes beginning in December each year. This typically results in an increase in
deposit and asset totals near year end and little or no growth in the first
quarter. Gross loans decreased $5.7 million, or 0.6%. This decrease was expected
because the loan pipeline decreased temporarily in the fourth quarter of 2004,
the bank sold a $3 million portion of a commercial account, a large commercial
relationship sought financing elsewhere, and the liquidation of $3.8 million in
non-performing loans. Investment securities increased $13.5 million or 2.7%,
which was funded by a reduction in federal funds sold.

Compared to March 31, 2004, loans, deposits, and assets increased 6.6%, 7.8%,
and 9.8%, respectively, largely due to the bank's continuing effort to expand
into the southern Wayne County, Michigan market. The Bank has four branches in
Wayne County, with deposits of $75 million and loans totaling $104 million as of
the end of the first quarter of 2005. A fifth branch is scheduled to open in
mid-May in Taylor, Michigan in a building that formerly served as a branch
location for another financial institution.

Management believes that the quality of the loan portfolio is continuing to
improve. Nonperforming assets ("NPAs") decreased $3.8 million, or 9.5% since
year end as we continue to work out the existing NPAs and improved lending
practices have resulted in a reduction of the amount of new NPAs being
identified. Most of the bank's lending is secured by real estate, which allows
us to maintain a lower ratio of Allowance for Loan Losses to NPAs compared to
other banks. Although net charge offs in the quarter were high at $2.1 million,
it includes liquidating three non-performing credits for a loss of $1.9 million.
In each of the three cases, the charge off was within the specified allocation
of the Allowance for Loan Losses, which provides support that our allowance
analysis methodology is effective.

A comparison of the income statements for the three months ended March 31, 2005
and 2004 shows a decrease of $18,000, or 0.1% in Net Interest Income. Interest
income on loans and investments increased $2.4 million, or 12.7% and interest
expense increased $2.4 million, or 40.2%. Average loans outstanding increased
$77.2 million and the average yield on those loans increased from 6.18% to
6.42%, resulting in an increase of $1.5 million in interest and fees on loans.
The fed rate increases that began late in the second quarter of 2004 and
continued into the second quarter of 2005 had a positive impact on our income as
our loan portfolio contains approximately $300 million of variable rate, prime
indexed loans. Average investments and fed funds sold increased $57.1 million
and the yield increased from 4.29% to 4.54%. Longer term market interest rates
have not increased as much as short term rates, limiting the amount of
improvement in our fixed rate loan and investment yields.

Average deposits increased 8.5% from $1.03 billion in the first quarter of 2004
to $1.118 billion in the first quarter of 2005. At the same time the average
cost of these deposits increased from 1.26% to 1.79%. The result was a 51.9%
increase in Interest on Deposits from $3.2 million to $4.9 million. Average
borrowed funds increased from $252.4 million in the first quarter of 2004 to
$288.1 million in the first quarter of 2005, while the average cost of these
borrowings increased from 4.27% to 4.75%. This increase in the cost of the
borrowed funds was due to the increases in the fed funds rate and the repricing
of $123 million of Federal Home Loan Bank advances that are indexed to three
month LIBOR. The cost of deposits increased slightly compared to the first
quarter of 2004 as customers continued to shift funds into higher yielding,
longer term certificates of deposit and we increased our use of brokered CDs as
a source of longer term funding. Additional movement of deposits from
transaction accounts and short term certificates into long term certificates, as
well as rising market rates, is expected to cause our deposit costs to increase
in the second quarter. We may also experience an increase in the cost of
borrowed funds as higher short term rates impact our LIBOR based variable rate
FHLB borrowings.

The Provision for Loan Losses was unchanged from the first quarter of 2004 at
$600,000. Although net charge offs increased from $340,000 in 2004 to $2.1
million in 2005, our analysis indicates that the Allowance for Loan Losses is
adequate to cover the losses expected in our portfolio. We believe that the
current provision level will be sufficient to maintain the adequacy of the
allowance.

Non interest income increased 6.8%. The table below summarizes the changes in
the components of non interest income (000s omitted) for the quarters ended:

</TABLE>

Trust Income improved due to improvements in the market values of trust accounts
and increases in the fees charged. The decrease in Deposit Account Service
Charges was due to the introduction of our free checking product in the second
quarter of 2004. The introduction of this product has resulted in an increase in
non interest bearing transaction accounts and contributed to

                                      -13-

<PAGE>

the increase in Other Deposit Account Related Fees, which primarily consists of
NSF and Stop Payment fees. Origination Fees and Gains on Mortgage Loans Sold
decreased, as expected, as rates increased slightly and refinance activity
slowed down. The income from Bank Owned Life Insurance policies decreased as the
yields on the policies owned began to decline in the fourth quarter of 2004.

Salaries and Employee Benefits increased only $184,000, or 4.1%, even though the
number of full time equivalent employees increased from 386 to 404. The annual
incentive compensation is based on corporate earnings performance compared to
our goal. During the first quarter of 2005 our earnings performance was below
goal, and as a result, the amount of incentive payment accrued was $104,000
lower in 2005. Occupancy Expense increased $141,000, or 17.5%, due to the Bank's
expansion into the southern Wayne County area, the replacement of the Temperance
branch in 2004, and the acceleration of depreciation expense on a parking lot in
downtown Monroe that will become the site of the company's new headquarters.
Other Expenses increased $515,000, or 19.9% largely due to higher expenses
related to non performing assets, particularly the costs associated with legal
and collection expenses and the costs of owning and maintaining Other Real
Estate Owned. Non interest expenses were higher than we anticipated for the
quarter, and we expect them to decrease slightly. Although our efficiency ratio
increased from 46.98% in the first quarter of 2004 to 51.76% in the first
quarter of 2005, it remains better than the average for comparable banks.

As a result of the above activity, Income Before Provision for Income Taxes
decreased $638,000, or 8.6%. The Provision for Income Taxes decreased $117,000,
or 5.9%, and reflects an effective tax rate of 27.6% compared to the effective
tax rate of 26.8% in the first quarter of 2004. The increase in the cost of
funds and the decrease in tax exempt interest income caused the increase in the
effective tax rate. Net Income decreased $521,000, or 9.6% compared to the first
quarter of 2005.

                              LIQUIDITY AND CAPITAL

The Corporation has maintained sufficient liquidity to fund its loan growth and
allow for fluctuations in deposit levels. Internal sources of liquidity are
provided by the maturities of loans and securities as well as holdings of
securities Available for Sale. External sources of liquidity include a line of
credit with the Federal Home Loan Bank of Indianapolis, and the Federal funds
lines that have been established with correspondent banks.

Total stockholders' equity of the Corporation was $153.6 million at March 31,
2005 and $155.3 million at December 31, 2004. The ratio of equity to assets was
9.9% at March 31, 2005 and 10.0% at December 31, 2004. Federal bank regulatory
agencies have set capital adequacy standards for Total Risk Based Capital, Tier
1 Risk Based Capital, and Leverage Capital. These standards require banks to
maintain Leverage and Tier 1 ratios of at least 4% and a Total Capital ratio of
at least 8% to be adequately capitalized. The regulatory agencies consider a
bank to be well capitalized if its Total Risk Based Capital is at least 10% of
Risk Weighted Assets, Tier 1 Capital is at least 6% of Risk Weighted Assets, and
Leverage Capital Ratio is at least 5%.

The following table summarizes the capital ratios of the Bank:

At March 31, 2005 and December 31, 2004, the Bank was in compliance with the
capital guidelines and is considered "well-capitalized" under regulatory
standards.

Market risk for the Bank, as is typical for most banks, consists mainly of
interest rate risk and market price risk. The Bank's earnings and the economic
value of its equity are exposed to interest rate risk and market price risk, and
monitoring this risk is the responsibility of the Asset/Liability Management
Committee (ALCO) of the Bank. The Bank's market risk is monitored monthly and it
has not changed significantly since year-end 2004.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Bank faces market risk to the extent that the fair values of its financial
instruments are affected by changes in interest rates. The Bank does not face
market risk due to changes in foreign currency exchange rates, commodity prices,
or equity prices. The asset and liability management process of the Bank seeks
to monitor and manage the amount of interest rate risk. This is accomplished by
analyzing the differences in repricing opportunities for assets and liabilities,
by simulating operating results under varying interest rate scenarios, and by
estimating the change in the net present value of the Bank's assets and
liabilities due to interest rate changes.

Each month, the Asset and Liability Committee (ALCO), which includes the senior
management of the Bank, estimates the effect of interest rate changes on the
projected net interest income of the Bank. The sensitivity of the Bank's net
interest income to changes in interest rates is measured by using a computer
based simulation model to estimate the impact on earnings of a gradual increase
or decrease of 100 basis points in the prime rate. The net interest income
projections are compared to a base case projection, which assumes no changes in
interest rates.

The Bank's ALCO has established limits in the acceptable amount of interest rate
risk, as measured by the change in the Bank's projected net interest income, in
its policy. Throughout the first three months of 2005, the estimated variability
of the net interest income was within the Bank's established policy limits.

The ALCO also monitors interest rate risk by estimating the effect of changes in
interest rates on the economic value of the Bank's equity each month. The actual
economic value of the Bank's equity is first determined by subtracting the fair
value of the Bank's liabilities from the fair value of the Bank's assets. The
fair values are determined in accordance with Statement of Financial Accounting
Standards Number 107, Disclosures about Fair Value of Financial Instruments. The
Bank estimates the interest rate risk by calculating the effect of market
interest rate shocks on the economic value of its equity. For this analysis, the
Bank assumes immediate parallel shifts of plus or minus 100 and 200 basis points
in interest rates. The discount rates used to determine the present values of
the loans and deposits, as well as the prepayment rates for the loans, are based
on Management's expectations of the effect of the rate shock on the market for
loans and deposits.

The Bank's ALCO has established limits in the acceptable amount of interest rate
risk, as measured by the change in economic value of the Bank's equity, in its
policy. Throughout the first three months of 2005, the estimated variability of
the economic value of equity was within the Bank's established policy limits.

The Bank's interest rate risk, as measured by the net interest income and
economic value of equity simulations, has not changed significantly from
December 31, 2004.

ITEM 4. CONTROLS AND PROCEDURES

The Company carried out an evaluation, under the supervision and with the
participation of the Company's management, including the Company's Chief
Executive Officer and Chief Financial Officer, of the effectiveness of the
design and operation of the Company's disclosure controls

                                      -15-

<PAGE>

and procedures as of March 31, 2005, pursuant to Exchange Act Rule 13a-15. Based
upon that evaluation, the Chief Executive Officer and Chief Financial Officer
concluded that the Company's disclosure controls and procedures were effective
as of March 31, 2005, in alerting them in a timely manner to material
information relating to the Company (including its consolidated subsidiaries)
required to be included in the Company's periodic SEC filings.

There was no change in the Company's internal control over financial reporting
that occurred during the Company's fiscal quarter ended March 31, 2005, that has
materially affected, or is reasonably likely to materially affect, the Company's
internal control over financial reporting.
