                                IBT BANCORP, INC.
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                   (UNAUDITED)

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been
prepared in accordance with generally accepted accounting principles for interim
financial information and with the instructions to form 10-Q and Article 10 of
Regulation S-X. Accordingly, they do not include all of the information and
footnotes required by generally accepted accounting principles for complete
financial statements. In the opinion of management, all adjustments (consisting
only of normal recurring accruals) considered necessary for a fair presentation
have been included. Operating results for the three and nine month periods ended
September 30, 2006 are not necessarily indicative of the results that may be
expected for the year ending December 31, 2006. For further information, refer
to the consolidated financial statements and footnotes thereto included in the
Corporation's annual report for the year ended December 31, 2005.

All amounts other than share and per share amounts have been rounded to the
nearest thousand ($000) in this report.

NOTE 2 - IMPLEMENTATION OF NEW ACCOUNTING STANDARD

On January 1, 2006, the Corporation adopted Statement of Financial Accounting
Standards No. 123R (revised 2004), "Share-Based Payment" (SFAS No. 123R) issued
by the Financial Accounting Standards Board (FASB). This statement requires that
compensation cost relating to share-based payment transactions be recognized in
financial statements and that this cost be measured based on the fair value of
the equity instruments issued. The adoption of this standard decreased dilutive
earnings per share by $.01 and $.03 for the three month and nine month periods
ended September 30, 2006, respectively.

NOTE 3 - COMPUTATION OF EARNINGS PER SHARE

Basic earnings per share represents income available to common stockholders
divided by the weighted-average number of common shares outstanding during the
period. Diluted earnings per share reflects additional common shares that would
have been outstanding if dilutive potential common shares had been issued, as
well as any adjustments to income that would result from the assumed issuance.
Potential common shares that may be issued by the Corporation relate solely to
outstanding shares in the Corporation's Deferred Director fee plan.

Earnings per common share have been computed based on the following:



                                                  Three months ended      Nine months ended

NOTE 4 - OPERATING SEGMENTS

The Corporation's reportable segments are based on legal entities that account
for at least 10% of operating results. The accounting policies are the same as
those discussed in Note 1 to the Consolidated Financial Statements in the
Corporation's annual report for the year ended December 31, 2005. The
Corporation evaluates performance based principally on net income and asset
quality of the respective segments. Summaries of selected financial information
for the Corporation's reportable segments as of and for the three and nine month
periods ended September 30 follow:

NOTE 5 - DEFINED BENEFIT PENSION PLAN

The Corporation has a defined benefit pension plan covering substantially all of
its employees. Benefits are based on years of service and the employees' five
highest consecutive years of compensation out of the last ten years of service.
The funding policy is to contribute annually the maximum amount that can be
deducted for federal income tax purposes. Contributions are intended to provide
not only for benefits attributed to services to date but also for those expected
to be earned in the future. The Corporation used a January 1, 2006 measurement
date for this pension plan.

The components of net periodic benefit cost related to the Corporation's
administered plan for the three and nine-month period ended September 30 were as
follows:

The Corporation contributed $1,128 and $545 to the pension plan during the nine
month periods ended September 30, 2006 and 2005, respectively. The Corporation
does not expect to make additional contributions to the plan during the
remainder of 2006.

NOTE 6 - SUBSEQUENT EVENT

On October 3, 2006, The Farwell State Savings Bank (FSSB) was acquired and
merged with and into Farmers State Bank, a wholly-owned subsidiary of the
Corporation. Under the terms of the Merger Agreement, for each share of FSSB
common stock, the shareholder of FSSB received 3.0382 shares of IBT Bancorp
common stock and $29.00 in cash. The Corporation issued an aggregate of 797,475
shares of IBT common stock valued at $30,448 and paid a total of $7,612 in cash
to FSSB shareholders, resulting in total consideration of $38,060.

NOTE 7 - RECENT ACCOUNTING PRONOUNCEMENTS

In September 2006, the FASB issued SFAS No. 157, "Fair Value Measurements" (SFAS
No. 157). SFAS No. 157 establishes a common definition for fair value to be
applied to US GAAP guidance requiring use of fair value, establishes a framework
for measuring fair value, and expands disclosure about such fair value
measurements. SFAS No. 157 is effective for fiscal years beginning after
November 15, 2007. The Corporation is currently assessing the impact of SFAS No.
157 on its consolidated financial position and results of operations.

In September 2006, the FASB issued SFAS No. 158, "Employers' Accounting for
Defined Benefit Pension and Other Postretirement Plans" (SFAS No. 158). SFAS No.
158 requires that employers recognize on a prospective basis the funded status
of their defined benefit pension and other postretirement plans on their
consolidated balance sheet and recognize as a component of other comprehensive
income, net of tax, the gains or losses and prior service costs or credits that
arise during the period but are not recognized as components of net periodic
benefit cost. SFAS No. 158 also requires additional disclosures in the notes to
financial statements. SFAS No. 158 is effective for years ending after December
15, 2006. While the Corporation is currently assessing the impact of SFAS No.
158 on its consolidated financial statements for 2006, it is expected that
adoption will not impact results of operations or cash flows, but will likely
result in a decrease to net financial position by an amount that will likely not
be material to other comprehensive loss.


                                       10



In September 2006, the SEC staff issued Staff Accounting Bulletin ("SAB") 108
"Considering the Effects of Prior Year Misstatements when Quantifying
Misstatements in Current Year Financial Statements" (SAB 108). SAB 108 requires
that public companies utilize a "dual-approach" in assessing the quantitative
effects of financial misstatements. This dual approach includes both an income
statement focused assessment and a balance sheet focused assessment. The
guidance in SAB 108 must be applied to annual financial statements for fiscal
years ending after November 15, 2006. The Corporation is currently assessing the
impact of adopting SAB 108 but does not expect that it will have a material
effect on its consolidated financial position or results of operations.

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

The following is management's discussion and analysis of the major factors that
influenced IBT Bancorp's financial performance. This analysis should be read in
conjunction with the Corporation's 2005 annual report and with the unaudited
condensed consolidated financial statements and notes, as set forth on pages 3
through 10 of this report.

CRITICAL ACCOUNTING POLICIES: A summary of the Corporation's significant
accounting policies is set forth in Note 1 of the Consolidated Financial
Statements included in the Corporation's Annual Report for the year ended
December 31, 2005. Of these significant accounting policies, the Corporation
considers its policies regarding the allowance for loan losses to be its most
critical accounting policies.

The allowance for loan losses requires management's most subjective and complex
judgment. Changes in economic conditions can have a significant impact on the
allowance for loan losses and therefore the provision for loan losses and
results of operations. The Corporation has developed appropriate policies and
procedures for assessing the adequacy of the allowance for loan losses,
recognizing that this process requires a number of assumptions and estimates
with respect to its loan portfolio. The Corporation's assessments may be
impacted in future periods by changes in economic conditions, the impact of
regulatory examinations, and the discovery of information with respect to
borrowers which is not known to management at the time of the issuance of the
consolidated financial statements. For additional discussion concerning the
Corporation's allowance for loan losses and related matters, see Provision for
Loan Losses and Allowance for Loan Losses in the Corporation's 2005 Annual
Report and herein.

NET INTEREST INCOME

Net interest income equals interest income less interest expense and is the
primary source of income for IBT Bancorp. Interest income includes loan fees of
$325 and $881 in the three and nine month periods ended September 30, 2006,
respectively, as compared to $305 and $849 during the same periods in 2005. For
analytical purposes, net interest income is adjusted to a "taxable equivalent"
basis by adding the income tax savings from interest on tax-exempt loans and
securities, thus making year-to-year comparisons more meaningful.

TABLE 3 - VOLUME AND RATE VARIANCE ANALYSIS
(Dollars in Thousands)

     The following table sets forth the effect of volume and rate changes on
interest income and expense for the periods indicated. For the purpose of this
table, changes in interest due to volume and rate were determined as follows:

     Volume Variance - change in volume multiplied by the previous year's rate.

     Rate Variance - change in the fully taxable equivalent (FTE) rate
     multiplied by the prior year's volume.

     The change in interest due to both volume and rate has been allocated to
volume and rate changes in proportion to the relationship of the absolute dollar
amounts of the change in each.

NET INTEREST INCOME, CONTINUED

As shown in Table 1, net interest income, on a fully taxable equivalent (FTE)
basis, was $6,550 for the three months ended September 30, 2006 compared to
$6,368 for the same period in 2005, an increase of $182 or 2.86%. This increase
was primarily the result of a $74,013 or 11.39% increase in earning assets,
which was funded by a $66,355 or 12.08% increase in interest bearing
liabilities. As shown in Table 3, these changes in volume provided the
Corporation with an additional $367 of FTE net interest income. The $367
increase was offset by a decrease of 0.30% in the FTE net yield on interest
earning assets, which resulted in a $185 decrease in FTE net interest income.
This 0.30% decrease in FTE rate was a result of the average rate earned on
interest earning assets rising slower than those paid on interest bearing
liabilities.

As shown in Table 2, net interest income, on a fully taxable equivalent (FTE)
basis, was $19,380 for the nine months ended September 30, 2006 compared to
$18,848 for the same period in 2005, an increase of $532 or 2.82%. This increase
was primarily the result of a $65,089 or 10.23% increase in earning assets,
which was funded by a $55,770 or 10.33% increase in interest bearing
liabilities. As shown in Table 3, these changes in volume provided the
Corporation with an additional $1,010 of FTE net interest income. The $1,010
increase was offset by a 0.26% decrease in the FTE net yield on interest earning
assets, which resulted in a $478 decrease in FTE net interest income. This 0.26%
decrease in FTE rate was a result of the average rate earned on interest earning
assets rising slower than those paid on interest bearing liabilities.

Management expects the high level of competition for funding to continue for the
remainder of the year, which will result in further tightening of the
Corporation's interest rate margins. However, the Corporation does anticipate
that projected increases in interest earning assets will continue to be strong
enough to overshadow the tightening interest rate margins and result in
continued increases in net interest margin.

ALLOWANCE FOR LOAN LOSSES

The viability of any financial institution is ultimately determined by its
management of credit risk. Net loans outstanding represent 66.3% of the
Corporation's total assets and is the Corporation's single largest concentration
of risk. The allowance for loan losses is management's estimation of potential
future losses inherent in the existing loan portfolio. Factors used to evaluate
the loan portfolio, and thus to determine the current charge to expense, include
recent loan loss history, financial condition of borrowers, amount of
nonperforming and impaired loans, overall economic conditions, and other
factors. The following table summarizes the Corporation's charge off and
recovery activity for the nine month periods ended September 30, 2006 and 2005.

The table also compares the Corporation's allowance for loan loss as a percent
of loans and loans classified as nonperforming as a percent of outstanding loans
to its peer group. The Corporation's peer group includes 416 holding companies
with assets between $500 million and $1.0 billion.

Since September 2005, the Corporation has experienced an increase in the percent
of loans classified as nonperforming. This is mainly being caused by the
increase in nonaccrual loans. However, based on management's analysis of the
allowance for loan losses, the current allowance stills falls within the
acceptable range and therefore the allowance for loan losses is adequate as of
September 30, 2006.

Since the first quarter of 2005, the Corporation has made substantial efforts to
increase noninterest income. To help achieve this goal, management analyzed
various fees related to deposit accounts, including service charges, NSF and
overdraft fees, and ATM and debit card fees. Based on this analysis, the
Corporation made any necessary adjustments to ensure that its fee structure fell
within a range of its competitors, while at the same time making sure that the
fees remained fair to deposit customers. Management does not expect significant
changes to its deposit fee structure for the remainder of 2006.

The competitive landscape in the Michigan title insurance industry has had both
positive and negative impacts on title insurance revenues. The Corporation has
seen increased title insurance activity resulting from other title insurance
companies closing offices around the state as a result of the struggling
Michigan economy and the decrease in volume of mortgage activity. These closures
have provided the Corporation with an opportunity to take advantage of the
decreased level of competition for business. However, these same factors make
continued increases in revenues challenging. Management does anticipate that
title insurance revenues will approximate current levels for the rest of the
year.

The increase in the cash value from corporate owned life insurance policies
relates to policies that had a carrying value of $11,337 as of September 30,
2006, and were included in other assets. These policies earned an average rate
of 3.59% and 3.49% during the nine month periods ended September 30, 2006 and
2005, respectively. Due to their preferential tax treatment, these policies have
a taxable equivalent rate of 5.43% and 5.28% as of September 30, 2006 and 2005,
respectively. These policies are placed with five different insurance companies
with an S & P rating of A- or better. The increase in income related to the
change of the cash surrender value of the policies can be attributed to both the
increases in rates and the purchase of additional policies in January 2006.

All other noninterest income includes losses on the sale of securities of $6 and
$109 which occurred in the three and nine month periods ended September 30,
2006, respectively, as compared to $2 and $0 in the same periods in 2005.
Management has determined that the additional interest income which will be
earned from the reinvestment of the proceeds of these sales will exceed the
losses recognized by approximately $25 by year end 2006.

Management is continuously analyzing noninterest expenses to determine where
expenditures can be decreased or held to modest increases. Management has been
fairly successful in stabilizing noninterest expenses as compared to the
percentage increase in total assets.

Leased employee salaries expense has increased due to normal merit increases,
and also due to the Corporation's growth in both size as well as complexity.
Management does not anticipate any significant changes in leased employee
salaries for the remainder of 2006.

Leased employee benefits have decreased substantially during the three and nine
month periods ended September 30, 2006, when compared to the same periods in
2005. This decrease is primarily attributed to the Corporation changing medical
insurance administrators. One of the benefits of the change was that the
Corporation's premium payments would be capped based on the current year's
projected claims. This cap allowed the Corporation to reduce its medical reserve
liability by $304 in the three month period ended September 30, 2006. Leased
employee benefit expenses are expected to approximate $313 a month for the rest
of 2006.

Upon completion of a new branch location for the Canadian Lakes branch of
Isabella Bank & Trust (IB&T), IB&T terminated a building lease for space that
had previously housed the Canadian Lakes employees. Pursuant to the terms of the
lease, IB&T paid $37 in one time penalties, which was included in building rent.
The Corporation anticipates that the building rent for the remainder of 2006 to
approximate the amounts paid in the first six months of the year.

Service contracts continue to increase significantly from year to year. These
increases are a result of the Corporation reinvesting in its technological
infrastructure as well as increases in fees charged by vendors. This constant
reinvestment helps the Corporation maintain a competitive edge in an ever
changing marketplace. Management does expect service contracts to remain at
current levels for the remainder of 2006 as a significant amount of annual
service contracts were renewed in June and July.

The Corporation continues to experience elevated costs associated with complying
with the Sarbanes-Oxley Act of 2002 (SOX). The costs associated with compliance
extend beyond the continued increases in SOX compliance fees and into other
areas including compensation expense. Management is continually analyzing ways
to minimize the adverse financial statement impact of SOX compliance through the
streamlining of the Corporation's loan and deposit operations. The Corporation
has also made staff changes in the internal audit department which are expected
to decrease auditing and SOX compliance fees.

All other expenses includes consulting fees, director's fees, legal fees,
postage fees, printing and supplies, title insurance expenses, as well as other
miscellaneous expenses that are not individually significant. These increases
are a result of overall increases in the cost of doing business.

Since December 2005, the Corporation has experienced strong loan growth. In the
first nine months of 2006, commercial loans have increased $26,608 and
residential real estate mortgages have increased $14,160. The increase in
commercial loans was driven by the establishment of a new business development
team at Isabella Bank and Trust. The increase in residential mortgage loans can
be attributed to various loan specials that were offered during 2006. Management
does anticipate that loan demand, particularly commercial loan demand, will
remain strong for the remainder of 2006.

The Corporation, as part of its goal to increase 2006 average assets by 8.0%
over 2005, also increased securities during the nine month period ended
September 30, 2006. To achieve this growth, however, the Corporation experienced
smaller interest margins than in the past. Management anticipates that the
security portfolio will approximate current levels for the remainder of 2006.

The Corporation, through its Banks, has established a policy that all amortized
fixed rate mortgage loans with maturities greater than 15 years will be sold.
During the nine month period ended September 30, 2006, the Corporation sold
$22,247 of mortgages as compared to $26,973 in mortgages for the same period in
2005. Management does not expect the sale of mortgages to fluctuate
significantly from current levels based on current market trends and the current
and projected interest rate environment.

The Corporation enjoyed a solid increase in deposits during the first nine
months of 2006. A significant portion of the deposit growth came in the form of
brokered and internet certificate of deposits. However, the increases in
deposits were not enough to fund the increases in loans and securities. To help
overcome this funding shortfall, the Corporation utilized wholesale borrowing
sources such as the Federal Home Loan Bank. Management is constantly monitoring
deposit account balances in an effort to maintain and increase the current
customer base, as deposit account rates are typically lower than those demanded
from internet and brokered deposits and wholesale borrowing sources. Management
is also performing market analyses to help ensure that the Corporation's
products remain attractive to consumers.

The Corporation observed a substantial decrease in escrow funds payable during
the first nine months of 2006. This decrease can be attributed to Internal
Revenue Code Section ( "IRC") 1031 exchange account balances being reinvested by
customers of IBT Title and Insurance Agency, Inc. ("IBT Title"). These IRC 1031
accounts allow owners of business or investment property to defer realized gains
from the sale of business or investment property if the funds are reinvested in
another property. As such, these balances can fluctuate significantly between
periods as the funds are reinvested. The Corporation does anticipate that these
1031 exchange accounts will continue to decrease through 2006 as the funds are
reinvested by IBT Title's customers.

LIQUIDITY

Liquidity management is designed to have adequate resources available to meet
depositor and borrower discretionary demands for funds. Liquidity is also
required to fund expanding operations, investment opportunities, and payment of
cash dividends. The primary sources of the Corporation's liquidity are cash,
cash equivalents, and available-for-sale investment securities.

As of September 30, 2006, cash and cash equivalents as a percentage of total
assets equaled 3.26%, versus 4.16% as of December 31, 2005. During the first
nine months of 2006, operating activities provided $1,561 of cash and financing
activities provided $46,518, while investing activities used $53,211. The
accumulated effect of the Corporation's operating, investing and financing
activities was a $5,132 decrease in cash and cash equivalents during the first
nine months of 2006.

In addition to cash and cash equivalents, investment securities available for
sale are another source of liquidity. Securities available for sale were
$193,268 as of September 30, 2006 and $183,406 as of December 31, 2005. In
addition to these primary sources of liquidity, the Corporation has the ability
to borrow in the federal funds market and at both the Federal Reserve Bank and
the Federal Home Loan Bank. The Corporation's liquidity is considered adequate
by management.

CAPITAL

The capital of the Corporation consists solely of common stock, surplus,
retained earnings, and accumulated other comprehensive loss. The overall capital
has increased $5,581 since December 31, 2005 primarily due to corporate
earnings. Accumulated other comprehensive loss decreased $473 due to unrealized
gains in available-for-sale securities during 2006.

There are no significant regulatory constraints placed on the Corporation's
capital. The Federal Reserve Board's current recommended minimum tier 1 and tier
2 capital to average assets requirement is 6.0%. The Corporation's tier 1 and
tier 2 capital to adjusted average assets, which consists of shareholders'
equity plus the allowance for loan losses less unamortized acquisition
intangibles, was 11.85% as of September 30, 2006.

The Federal Reserve Board has established a minimum risk based capital standard.
Under this standard, a framework has been established that assigns risk weights
to each category of on- and off-balance sheet items to arrive at risk adjusted
total assets. Regulatory capital is divided by the risk adjusted assets with the
resulting ratio compared to the minimum standard to determine whether a bank has
adequate capital. The minimum standard is 8%, of which at least 4% must consist
of equity capital net of goodwill. The following table sets forth the
percentages required under the Risk Based Capital guidelines and the
Corporation's ratios as of September 30, 2006:

FINANCIAL INSTRUMENTS WITH OFF-BALANCE SHEET ARRANGEMENTS

The Corporation is party to financial instruments with off-balance-sheet risk.
These instruments are entered into in the normal course of business to meet the
financing needs of its customers. These financial instruments, which include
commitments to extend credit and standby letters of credit, involve, to varying
degrees, elements of credit and interest rate risk in excess of the amounts
recognized in the consolidated balance sheets. The contract or notional amounts
of these instruments reflect the extent of involvement the Corporation has in a
particular class of financial instruments.

The Corporation's exposure to credit loss in the event of nonperformance by the
other party to the financial instruments for commitments to extend credit and
standby letters of credit is represented by the contractual notional amount of
those instruments. The Corporation uses the same credit policies in deciding to
make these commitments as it does for extending loans to customers.

Commitments to extend credit, which totaled $86,660 at September 30, 2006, are
agreements to lend to a customer as long as there is no violation of any
condition established in the contract. Commitments generally have variable
interest rates, fixed expiration dates, or other termination clauses and may
require the payment of a fee. Since many of the commitments are expected to
expire without being drawn upon, the total commitment amounts do not necessarily
represent future cash requirements.

Standby letters of credit are conditional commitments issued by the Corporation
to guarantee the performance of a customer to a third party. Those guarantees
are primarily issued to support private borrowing arrangements, including
commercial paper, bond financing, and similar transactions. At September 30,
2006, the Corporation had a total of $1,733 in outstanding standby letters of
credit.

Generally, these commitments to extend credit and letters of credit mature
within one year. The credit risk involved in these transactions is essentially
the same as that involved in extending loans to customers. The Corporation
evaluates each customer's credit worthiness on a case-by-case basis. The amount
of collateral obtained, if deemed necessary by the Corporation upon the
extension of credit, is based on management's credit evaluation of the borrower.
Collateral held varies but may include accounts receivable, inventory, property,
plant and equipment, and other income producing commercial properties.

Isabella Bank and Trust (IB&T), a subsidiary of the Corporation, sponsors the
IBT Foundation (the "Foundation"), which is a nonprofit entity formed for the
purpose of distributing charitable donations to recipient organizations
generally located in the communities serviced by Isabella Bank and Trust. IB&T
periodically makes charitable contributions in the form of cash transfers to the
Foundation. The Foundation is administered by members of the Corporation's Board
of Directors. The assets and transactions of the Foundation are not included in
the consolidated financial statements of IBT Bancorp, Inc. The assets of the
Foundation as of September 30, 2006 were $1,358.

FORWARD LOOKING STATEMENTS

This report contains certain forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended, and Section 21E of the
Securities Exchange Act of 1934, as amended. The Corporation intends such
forward-looking statements to be covered by the safe harbor provisions for
forward-looking statements contained in the Private Securities Reform Act of
1995, and is including this statement for purposes of these safe harbor
provisions. Forward-looking statements, which are based on certain assumptions
and describe future plans, strategies and expectations of the Corporation, are
generally identifiable by use of the words "believe," "expect," "intend,"
"anticipate," "estimate," "project," or similar expressions. The Corporation's
ability to predict results or the actual effect of future plans or strategies is
inherently uncertain. Factors which could have a material adverse effect on the
operations and future prospects of the Corporation and the subsidiaries include,
but are not limited to, changes in: interest rates, general economic conditions,
legislative/regulatory changes, monetary and fiscal policies of the U.S.
Government, including policies of the U.S. Treasury and the Federal Reserve
Board, the quality or composition of the loan or investment portfolios, demand
for loan products, deposit flows, competition, demand for financial services in
the Corporation's market area, and accounting principles, policies and
guidelines. These risks and uncertainties should be considered in evaluating
forward-looking statements and undue reliance should not be placed on such
statements. Further information concerning the Corporation and its business,
including additional factors that could materially affect the Corporation's
financial results, is included in the Corporation's filings with the Securities
and Exchange Commission.

ITEM 3 - QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The Corporation's primary market risks are interest rate risk and, to a lesser
extent, liquidity risk. The Corporation has very limited foreign exchange risk
and holds no trading account assets, nor does it utilize interest rate swaps or
derivatives in the management of its interest rate risk. The Corporation does
have a significant amount of loans extended to borrowers involved in
agricultural production. Cash flow and ability to service debt of such customers
is largely dependent on growing conditions and the commodity prices for corn,
soybeans, sugar beets, milk, beef and a variety of dry beans. The Corporation
mitigates these risks by using conservative price and production yields when
calculating a borrower's available cash flow to service their debt.

Interest rate risk ("IRR") is the exposure to the Corporation's net interest
income, its primary source of income, to changes in interest rates. IRR results
from the difference in the maturity or repricing frequency of a financial
institution's interest earning assets and its interest bearing liabilities.
Interest rate risk is the fundamental method in which financial institutions
earn income and create shareholder value. Excessive exposure to interest rate
risk could pose a significant risk to the Corporation's earnings and capital.

The Federal Reserve, the Corporation's primary Federal regulator, has adopted a
policy requiring the Board of Directors and senior management to effectively
manage the various risks that can have a material impact on the safety and
soundness of the Corporation. The risks include credit, interest rate,
liquidity, operational, and reputational. The Corporation has policies,
procedures and internal controls for measuring and managing these risks.
Specifically, the IRR policy and procedures include defining acceptable types
and terms of investments and funding sources, liquidity requirements, limits on
investments in long term assets, limiting the mismatch in repricing opportunity
of assets and liabilities, and the frequency of measuring and reporting to the
Board of Directors.

The Corporation uses several techniques to manage interest rate risk. The first
method is gap analysis. Gap analysis measures the cash flows and/or the earliest
repricing of the Corporation's interest bearing assets and liabilities. This
analysis is useful for measuring trends in the repricing characteristics of the
balance sheet. Significant assumptions are required in this process because of
the imbedded repricing options contained in assets and liabilities. A
substantial portion of the Corporation's assets are invested in loans and
investment securities. These assets have imbedded options that allow the
borrower to repay the balance prior to maturity without penalty. The amount of
prepayments is dependent upon many factors, including the interest rate of a
given loan in comparison to the current interest rates, for residential
mortgages the level of sales of used homes, and the overall availability of
credit in the market place. Generally, a decrease in interest rates will result
in an increase in the Corporation's cash flows from these assets. Investment
securities, other than those that are callable, do not have any significant
imbedded options. Saving and checking deposits may generally be withdrawn on
request without prior notice. The timing of cash flow from these deposits is
estimated based on historical experience. Time deposits have penalties which
discourage early withdrawals. Cash flows may vary based on current offering
rates, competition, customer need for deposits, and overall economic activity.

The second technique used in the management of interest rate risk is to combine
the projected cash flows and repricing characteristics generated by the gap
analysis and the interest rates associated with those cash flows and projected
future interest income. By changing the amount and timing of the cash flows and
the repricing interest rates of those cash flows, the Corporation can project
the effect of changing interest rates on its interest income.

The following table provides information about the Corporation's assets and
liabilities that are sensitive to changes in interest rates as of September 30,
2006. The Corporation has no interest rate swaps, futures contracts, or other
derivative financial options, except for derivative loan commitments, which are
not significant. The principal amounts of assets and time deposits maturing were
calculated based on the contractual maturity dates. Savings and NOW accounts are
based on management's estimate of their future cash flows.

ITEM 4 - CONTROLS AND PROCEDURES

DISCLOSURE CONTROLS AND PROCEDURES

The Corporation's management carried out an evaluation, under the supervision
and with the participation of the Principal Executive Officer and Principal
Financial Officer, of the effectiveness of the design and operation of the
Corporation's disclosure controls and procedures (as such term is defined in
Rules 13a-15(e) and 15(d)-15(e) under the Securities Exchange Act of 1934 (the
"Exchange Act")) as of September 30, 2006, pursuant to Exchange Act Rule 13a-15.
Based upon that evaluation, the Principal Executive Officer and Principal
Financial Officer concluded that the Corporation's disclosure controls and
procedures as of September 30, 2006, were effective to ensure that information
required to be disclosed by the Corporation in reports that it files or submits
under the Exchange Act is recorded, processed, summarized and reported within
the time periods specified in Securities and Exchange Commission rules and
forms.

CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING

During the most recent fiscal quarter, no change occurred in the Corporation's
internal control over financial reporting that materially affected, or is likely
to materially affect, the Corporation's internal control over financial
reporting. The Corporation is currently evaluating what changes, if any, might
be necessary in internal control arising as a result of the October 3, 2006
acquisition of the Farwell State Savings Bank.
