                               MBT FINANCIAL CORP.
             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 operates twenty-one offices in Monroe County, Michigan and one
office in Wayne County, Michigan. 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.

At the April 6, 2000 Annual Meeting of Shareholders of Monroe Bank & Trust,
shareholders approved a proposal that resulted in the Bank reorganizing into a
one-bank holding company. The holding company formation involved merging Monroe
Bank & Trust with Monroe Interim Bank, a state chartered bank organized solely
for the purpose of this transaction. The merger of Monroe Bank & Trust and
Monroe Interim Bank, a combination of entities under common control, was treated
in a manner similar to a pooling of interests. The financial information for all
prior periods was restated in the unaudited consolidated financial statements
for MBT Financial Corp. to present the statements as if the merger had been in
effect for all periods presented.

The reorganization resulted in an exchange of the Monroe Bank & Trust common
stock for MBT Financial Corp. common stock. The exchange rate was two shares of
MBT Financial Corp. for each share of Monroe Bank & Trust. Monroe Bank & Trust
previously had 10,000,000 common shares authorized and outstanding, with a par
value of $3.125 per share. MBT Financial Corp. has 30,000,000 common shares
authorized, of which 20,000,000 were outstanding after the reorganization. The
MBT Financial Corp. common stock has no par value. Monroe Bank & Trust is now a
wholly owned subsidiary of MBT Financial Corp., a registered bank holding
company.

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.

Comprehensive Income is comprised of Net Income and Other Comprehensive Income,
which consists of the change in net unrealized gains (losses) on securities
available for sale, net of tax.


2. EARNINGS PER SHARE
The calculation of net income per common share for the quarters ended June 30 is
as follows:

Loans are placed in a nonaccrual status when, in the opinion of Management, the
collection of additional interest is doubtful. In the opinion of Management, all
impaired loans are in nonaccrual status. Allowances for these loans are included
in the allowance for loan losses. All cash received on nonaccrual loans is
applied to the principal balance. Nonperforming assets consists 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 investments securities that are 90 days or more past due on the
interest or principal payments. The following table summarizes nonperforming
assets (000's omitted):

</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 large loans and pools of homogeneous small loans, portfolio
seasoning, changes in collateral values, and detailed reviews of specific large
loan relationships. For large 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,
the fair value of the collateral, or the loan's observable market price.

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 obtain control
of 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.

Financial instruments whose contractual amounts represent off-balance sheet
credit risk were as follows (000s omitted):

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)
                                   (CONTINUED)


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, generally have fixed expiration dates or other termination clauses,
and require payment of a fee. 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 no established maturity dates,
but are payable on demand. Home equity lines of credit are secured by real
estate mortgages, have no established maturity dates, but are payable 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," "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.

The Corporation experienced a small increase of $46.6 million in deposits since
the beginning of the year, representing a 4.7% increase. Demand Deposits
decreased $8.1 million while Savings Deposits increased $63.3 million and Other
Time Deposits decreased $8.6 million. Local loan demand has begun to moderate,
with Loans increasing only $21.6 million, or 2.7% since the beginning of the
year. The increase in deposits and a decrease of $5.8 million in Federal funds
sold funded the loan growth and the increase of $32.7 million in investment
securities.

                   THREE MONTHS ENDED JUNE 30, 2001 AND 2000

A comparison of the income statements for the three months ended June 30, 2001
and 2000 shows a 7% increase in Net Interest Income. The largest interest
income dollar changes were in Interest and Fees on Loans, increasing
$1,445,000, or 8% and interest on Obligations of U.S. Government Agencies,
increasing $648,000, or 22%. The increase in Interest and Fees on Loans was the
result of an increase of $109 million, or 15% in average loans outstanding. The
average yield on these loans decreased from 8.82% to 8.34%. The increase in
interest on Obligations of U.S. Government Agencies was a result of an increase
of $39 million, or 22%, in the average investment in these securities. The
average yield on these investments was unchanged.

Average interest bearing deposits increased from $831 million to $907 million,
while at the same time the average cost of these deposits decreased from 4.66%
to 4.35%. The result was a small increase in Interest on Deposits of $217,000,
or 2%. Average borrowed funds increased from $157 million to $226 million while
the average cost of these borrowings decreased from 5.99% to 5.64%. The interest
expense related to these borrowings increased $846,000. The borrowings were
increased as the Bank expanded its leverage strategy, which utilizes Federal
Home Loan Bank advances to fund investment in loans and securities.

The Provision for Loan Losses decreased $600,000, or 40%. The Provision for Loan
Losses was higher in 2000 as faster loan growth necessitated an increase in the
Allowance for Loan Losses. Trust Income increased $160,000, or 19%, and Service
Charges on Deposit Accounts increased $147,000, or 28%, as a result of fee
increases implemented in the third quarter of 2000. Other


                                      -13-

Income increased $507,000, or 70%, as a result of the sale of a portion of the
Bank's credit card portfolio, which was sold at a profit of $408,000 in the
second quarter of 2001.

Salaries and Employee Benefits increased $263,000, Occupancy Expense increased
$18,000, and Other Expenses increased $317,000, compared to the second quarter
of 2000.

As a result of the above activity, Income Before Provision for Income Taxes
showed a significant increase of $1,713,000, or 23%, and the Provision for
Income Taxes increased $444,000, or 22%. Net Income increased $1,268,000, or
24%.

                    SIX MONTHS ENDED JUNE 30, 2001 AND 2000

A comparison of the income statements for the six months ended June 30, 2001
and 2000 shows a 4% increase in Net Interest Income. The largest interest
income dollar changes were in Interest and Fees on Loans, increasing
$4,067,000, or 12%, interest on Other Securities, increasing $422,000, or 9%,
and interest on Obligations of States and Political Subdivisions, decreasing
$402,000, or 10%. The increase in Interest and Fees on Loans was the result of
an increase of $118 million, or 16% in average loans outstanding. The average
yield on these loans decreased from 8.78% to 8.52%. The increase in interest on
Other Securities was the result of an increase of $24 million in the average
investment in Other Securities. The average yield on these investments
decreased from 7.31% to 7.02%. The decrease in interest on Obligation of States
and Political Subdivisions was the result of a decrease of $21 million, or 16%
in the average investment in Obligations of States and Political Subdivisions.

Average interest bearing deposits increased from $831 million to $901 million,
or 8%, while at the same time the average cost of these deposits was unchanged.
The result was an increase in Interest on Deposits of $1,557,000, or 8%. Average
borrowed funds increased from $146 million to $226 million while the average
cost of these borrowings decreased from 5.92% to 5.65%. The interest expense
related to these borrowings increased $2,034,000. The borrowings were
increased as the Bank expanded its leverage strategy, which utilizes Federal
Home Loan Bank advances to fund investment in loans and securities.

The Provision for Loan Losses increased $2.3 million, or 77% as the Allowance
for Loan Losses was increased significantly in the first quarter of 2001. The
Allowance for Loan Losses was increased $2.5 million, or 24% since December 31,
2000, in order to maintain its adequacy as the economy began showing signs of
weakening and nonperforming loans increased. The Allowance for Loan Losses is
now 1.58% of Loans, compared to 1.31% as of December 31, 2000. Nonperforming
assets, which consist of nonaccrual loans, loans 90 days past due, restructured
loans, other real estate owned, and investment securities in default, have
increased from $21.6 million at December 31, 2000 to $29.3 million at June 30,
2001. Nonaccrual loans account for $25.6 million of the nonperforming assets as
of June 30, 2001. Nonaccrual loans secured by real estate are $13.6 million, or
46% of the nonperforming assets.

Trust Income increased $320,000, or 19%, and Service Charges on Deposit
Accounts increased $288,000, or 27%, as the result of increases in the fees
charged. Other Income increased $707,000, or 54%, which is attributable to the
gain on the sale of a portion of the Bank's credit card portfolio in the second
quarter of 2001 and the Bank Owned Life Insurance (BOLI) that was purchased in
the third quarter of 2000. The gain on the sale of the portion of the credit
card portfolio was $408,000 and the amount of Other Income resulting from the
BOLI in the six months ended June 30, 2001 was $398,000.

Salaries and Employee Benefits increased $511,000, Occupancy Expense increased
$85,000, and Other Expenses increased $418,000, compared to the first six
months of 2000.

As a result of the above activity, Income Before Provision for Income Taxes
showed a small decrease of $1,073,000 or 7%, and the Provision for Income Taxes
decreased $282,000, or 7%. Net Income decreased $791,000, or 7%.

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 $159,920,000 at June 30, 2001
and $150,955,000 at December 31, 2000. The ratio of equity to assets was 11.1%
at June 30, 2001 and 10.9% at December 31, 2000. Federal bank regulatory
agencies have set capital adequacy standards for Total Risk Based Capital, Tier
1 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:

</TABLE>

At June 30, 2001 and December 31, 2000, 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 market risk is monitored monthly
and has not changed significantly since year-end 2000.
