                               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 "Company") 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
business 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 was treated as 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 are outstanding. 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 Company 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.

Other Comprehensive Income (Loss) consists of the change in net unrealized gains
(losses) on securities available for sale, net of tax.

(EPS) for the periods indicated are as follows:

Meeting of Shareholders on April 6, 2000. The options were granted at the price
of $18.125, which was the fair market value of the Company's common stock on the
date the options were granted. The plan provides for the award of stock options,
stock, and restricted stock to directors, selected employees, and consultants.
The Board of Directors of the Company has full discretion to make awards under
the plan, up to 1,000,000 shares, or 5% of the outstanding common shares.

3. LOANS
The Bank grants commercial, consumer, and mortgage loans primarily to customers
in Monroe 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.

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 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 on-balance-sheet instruments.

Financial instruments whose contract amounts represent off-balance-sheet credit
were as follows:

Commitments to extend credit:

      Unused portion of credit card lines of credit                        30,522        29,115

Standby letters of credit and financial guarantees written                 18,960        11,834
</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, 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.

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, and real estate that
has been acquired in full or partial satisfaction of loan obligations or upon
foreclosure. The following table summarizes nonperforming assets (000's

                                         ============================
</TABLE>


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 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.

The Bank elected early adoption of SFAS 133, "Accounting for Derivative
Instruments and Hedging Activities", effective April 1, 1999. The provisions of
SFAS 133 require the Bank to recognize all derivative instruments as assets or
liabilities in its statement of condition and to report them at their fair
value. The provisions of SFAS 133 also allowed the Bank to reclassify securities
that were classified as Held to Maturity as Available for Sale or as Trading.
Upon adoption of SFAS 133, the Bank reclassified certain Held to Maturity
Obligations of States and Political Subdivisions as Available for Sale
Obligations of States and Political Subdivisions. The value of the securities
reclassified on April 1, 1999 was $7,990,185.

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

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 was treated as 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 are outstanding. 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 Company experienced a slight increase of $5.1 million in deposits since the
beginning of the year, representing a 0.6% increase. Demand Deposits decreased
$7.9 million and Savings Deposits decreased $31.7 million while Other Time
Deposits increased $45.5 million. Local loan demand has continued to be strong,
with Loans increasing $91.0 million, or 13.1% since the beginning of the year.
This loan growth has been funded through the use of borrowed funds, the increase
in deposits, and a decrease of $50.1 million in investments. During the first
quarter, the Company redeemed its Cumulative Preferred Stock, which had a par
value of $200,000.

A comparison of the income statements for the three months ended September 30,
2000 and 1999 shows that Net Interest Income increased $1,154,000, or 10%, while
Net Income increased $229,000, or 5%. The largest interest income dollar changes
were in Interest and Fees on Loans, increasing $2,708,000, or 18%, interest on
Other Securities, increasing $1,442,000, or 169%, and interest on Obligations of
U.S. Government Agencies, increasing $698,000, or 29%. Average loans outstanding
increased $84 million while the average yield on these loans increased from
8.44% to 8.96%. The average investment in Other Securities increased $63 million
while the average yield on these investments increased from 6.87% to 7.35%. The
average investment in Obligations of U.S. Government Agencies increased $31
million while the average yield on these investments increased from 6.54% to
6.99%. Average interest bearing deposits decreased from $860 million to $830
million, while at the same time the average cost of these deposits increased
from 4.36% to 4.91%. The result was an increase in Interest on Deposits of
$781,000, or 8.3%. Average borrowed funds increased from $4 million to $169

Total stockholders equity of the Company was $149,037,000 at September 30, 2000
and $139,647,000 at December 31, 1999. The ratio of equity to assets was 11.6%
and 11.5% at each period end, respectively. Federal bank regulatory agencies
have set capital adequacy standards for Total Risk Based Capital, Tier 1 Risk
Based Capital, and Capital Leverage. 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 September 30, 2000 and December 31, 1999, 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 1999.
